In America, a person has a 1 in 3 chance of falling each year once they reach the age of 65. When someone falls, they risk bodily injury. There are products available to help people when they fall, but they are only effective once a person reaches a point where they are at risk of falling. In order to reduce an individualâ s chance of falling as they age, preventive measures must be taken before the problems develop. With the use of digital technology, adults can be properly instructed on how to keep they bodies strong and balanced for there golden years. This thesis documents the research, conceptualization, and development of the Xcel Sleeve.

With the arrival of the digital age, faster internet speeds, and greater storage capacities in our computers, digital piracy is on the rise. Neither the illegality of piracy nor the unethical nature of doing so has stopped people from partaking in the act. Studies show that tens of billions of dollars of pirated goods are downloaded every year, yet our policies fail to solve the issue of digital copyright infringement. The biggest issues contributing to the problem are the lack of a policy that consumers take seriously in combination with some digital goods being too expensive in their current state of distribution. This thesis is aimed at taking a direct approach to reduce digital piracy from two different angles. The first angle deals with the incentive structure of society and the need for a government backed policy that has legitimacy in the view of United States citizens and the second angle is the creation of an alternative distribution model for digital software as a service based platform.

As the connectivity of home devices elevates so does the volume and sophistication of cyber attacks consistently grow. Therefore, the need for network security and availability becomes more significant. Numerous sorts of countermeasures like firewalls and router-based packet filtering have been put in place, although these alone are not enough to brace the network from unauthorised access. One of the most efficient methods of stopping network adversaries is using Intrusion Detection and Prevention Systems (IDPS). The goal of an IDPS is to stop security attacks before they can be successfully carried out. In this paper, I looked at four network attacks namely; probing, denial of service, remote to user and user to root and improved their respective Snort rules to optimize processing time and capturing capacity using regular expressions and fast pattern. Snort with improved rules captured 100% of the attacks launched to the network while without the improved rules, Snort captured between 0% to 60% of the attacks launched to the network making an improvement of 40%.

Objetivo: Analisar custo-efetividade, comparando as retinografias realizadas em pacientes diabeticos, utilizando sistema digital para captura e teletransmissao de imagens a distancia e o sistema de retinografia convencional. Metodos: Avaliacao de amostra estatisticamente representativa de 840 diabeticos, divididos em quatro grupos de 210 pacientes, com criterios de inclusao e exclusao bem definidos, assim distribuidos: A1 - retinografia digital de pacientes a distancia, A2 - retinografia convencional de pacientes distantes realizada em Porto Alegre, 131 - retinografia digital de comunidade local e 132 - retinografia convencional de comunidade local. Todos os pacientes serao avaliados com base na historia clinica, medida da acuidade visual e realizarao duas retinografias em cada olho, uma centrada na papila e outra na macula. Os grupos A1 e 131 farao retinografia digital com Camara Canon CR6-45NM ou similar e os grupos A2 e 132 com camara convencional de 50 graus marca Topcon com filme de 35mm. Os pacientes do grupo A1 serao fotografados em seu local de origem, por tecnologo treinado e as imagens transmitidas via Internet ao Centro de Leitura em Porto Alegre. Os pacientes dos grupos 131 (digital), A2 e 132 (convencional) serao fotografados em Porto Alegre. Resultados: A analise de custo da retinografia digital e 27 por cento inferior ao da retinografia convencional. Comparando custo das retinografias convencional (A2 e 132) e digital (A1 e 131) dentro de cada grupo observamos: grupo A1, reducao de custo da ordem de 9 por cento em relacao ao grupo A2; reducao de 6,5 por cento quando comparamos o grupo 131 com o grupo 132; reducao de 6 por cento no custo do grupo A1 comparado ao grupo 132 e constatamos ainda nao haver diferenca de custo entre os grupos da retinografia digital A1 e 131. Conclusao: O custo-efetividade da retinografia digital com camara nao midriatica e inferior ao da retinografia convencional, contudo esta reducao e mais evidente nos pacientes de localidades distantes, fotografados em seu local de origem. O sistema de retinografia digital, apresenta vantagens quando comparado ao sistema convencional: evita os gastos de deslocamento, facilita a aderencia ao projeto, estimula os programas preventivos de triagem e deteccao e a consequente prevencao da cegueira ocasionada pela Retinopatia Diabetica, com o onus economico e social que ela acarreta
Purpose: analise cost-effectiveness comparing color fundus pictures on diabetic patients using a digital sistem for acquiring and transmitting images and conventional color fundus pictures taken on conventional camera. Methods: Evaluation of 840 diabetic patients divided in four groups: (A1= digital imaging from patients extra-clinics setting, A2= conventional retinography performed on patients from Porto Alegre originally from another city, B1= digital imaging of patients from Porto Alegre e B2= conventional retinography performed on patients from Porto Alegre). All the patients will be evaluated with clinical history, visual acuity and color fundus pictures (50 degree Topcon conventional fundus camera) or non midryatic digital imaging (Canon CR6-45 NM). Patients from group A1 will be evaluated by te chnicians on their own town and two images will be taken from each eye with the non mydriatic camera and the images transmitted to the reading center in Porto alegre via internet. B1, A2 e B2 groups will be evaluated in Porto Alegre. Results: The cost analisis demonstrated that the cost of digital imaging is 27% lower than the color fundus pictures taken with the conventional fundus camera. The cost of conventional retinography (A2 e B2) and digital imaging (A1 e B1) each group was observed: reduction of 9% was observed when comparing group A1(digital imaging from patients outside clinical setting) and A2 (conventional retinography performed on patients from Porto Alegre originally from another city); and 6.5% cost reduction was observed when comparing groups B1(digital imaging of patients from Porto Alegre) and B2 (conventional retinography performed on patients from Porto Alegre). When comparing groups A1 and B2, a 6% cost reduction was observed and no cost benefit was found comparing groups A1 and B1. Conclusion: Cost-effectiveness of the digital imaging of ocular fundus is lower than color fundus pictures taken with conventional fundus camera, but it is more evident on patients extra clinics, specially those patients imaged on their own town. The digital system has many advantages, specially because it eliminates costs with patients displacement, helps on the compliance to treatment, stimulates programs for prevention of blindness, screening and prevention of blindness due to the diabetic retinopathy with social and economic costs.

Resumo:

Background Cardiovascular disease (CVD) risk assessment can improve outcomes, but novel methods to identify high-risk patients and deliver prevention programs are needed. Rapid Access Cardiology (RAC) services can provide rapid risk assessment but have not been evaluated in Australia. Within RAC there is the potential to also implement systems that identify high-risk patients and manage risk using novel strategies. Mobile health (mHealth) provides a unique opportunity to deliver prevention programs and may influence behaviours. There is, however, limited evidence for mHealth efficacy in primary prevention. Aims To assess the utility of RAC to identify and manage patients at high-risk of CVD, and to leverage this opportunity to provide preventative care using mHealth. Methods and results Methods used include cohort studies, data audits, secondary analyses, and a randomised controlled trial (RCT). Part 1 evaluates the role of RAC for the assessment of suspected CVD and identifies gaps in risk factor assessment. RAC for chest pain and arrhythmia safely reduced unplanned hospitalisation. Many patients had multiple uncontrolled risk factors, but gaps exist in electronic data required to quantify risk. Part 2 examines the role of mHealth to improve CVD prevention, and identifies factors associated with effective text message-based programs. Message intent significantly influenced engagement. Patients with higher baseline risk were more likely to change behaviour. Part 3 evaluates text messages for CVD primary prevention via a RCT in higher risk patients from RAC. The primary outcome (difference in the proportion with 3 uncontrolled risk factors) was not significant at 6 months. However, the intervention improved risk factor control from baseline. Conclusion The results support a novel healthcare model which utilises digital health to optimise CV risk assessment and provide continued support to patients at elevated risk extending beyond the traditional clinical interface.

Whelan, Maxine E. "Persuasive digital health technologies for lifestyle behaviour change". Thesis, Loughborough University, 2018. https://dspace.lboro.ac.uk/2134/32507.

Resumo:

BACKGROUND. Unhealthy lifestyle behaviours such as physical inactivity are global risk factors for chronic disease. Despite this, a substantial proportion of the UK population fail to achieve the recommended levels of physical activity. This may partly be because the health messages presently disseminated are not sufficiently potent to evoke behaviour change. There has been an exponential growth in the availability of digital health technologies within the consumer marketplace. This influx of technology has allowed people to self-monitor a plethora of health indices, such as their physical activity, in real-time. However, changing movement behaviours is difficult and often predicated on the assumption that individuals are willing to change their lifestyles today to reduce the risk of developing disease years or even decades later. One approach that may help overcome this challenge is to present physiological feedback in parallel with physical activity feedback. In combination, this approach may help people to observe the acute health benefits of being more physically active and subsequently translate that insight into a more physically active lifestyle. AIMS. Study One aimed to review existing studies employing fMRI to examine neurological responses to health messages pertaining to physical activity, sedentary behaviour, smoking, diet and alcohol consumption to assess the capacity for fMRI to assist in evaluating health behaviours. Study Two aimed to use fMRI to evaluate physical activity, sedentary behaviour and glucose feedback obtained through wearable digital health technologies and to explore associations between activated brain regions and subsequent changes in behaviour. Study Three aimed to explore engagement of people at risk of type 2 diabetes using digital health technologies to monitor physical activity and glucose levels. METHODS. Study One was a systematic review of published studies investigating health messages relating to physical activity, sedentary behaviour, diet, smoking or alcohol consumption using fMRI. Study Two asked adults aged 30-60 years to undergo fMRI whilst presented personalised feedback on their physical activity, sedentary behaviour and glucose levels, following a 14-day wear protocol of an accelerometer, inclinometer and flash glucose monitor. Study Three was a six-week, three-armed randomised feasibility trial for individuals at moderate-to-high risk of developing type 2 diabetes. The study used commercially available wearable physical activity (Fitbit Charge 2) and flash glucose (Freestyle Libre) technologies. Group 1 were offered glucose feedback for 4 weeks followed by glucose plus physical activity feedback for 2 weeks (G4GPA2). Group 2 were offered physical activity feedback for 4 weeks followed by glucose plus physical activity feedback for 2 weeks (PA4GPA2). Group 3 were offered glucose plus physical activity feedback for six weeks (GPA6). The primary outcome for the study was engagement, measured objectively by time spent on the Fitbit app, LibreLink app (companion app for the Freestyle Libre) as well as the frequency of scanning the Freestyle Libre and syncing the Fitbit. RESULTS. For Study One, 18 studies were included in the systematic review and of those, 15 examined neurological responses to smoking related health messages. The remaining three studies examined health messages about diet (k=2) and physical activity (k=1). Areas of the prefrontal cortex and amygdala were most commonly activated with increased activation of the ventromedial prefrontal cortex predicting subsequent behaviour (e.g. smoking cessation). Study Two identified that presenting people with personalised feedback relating to interstitial glucose levels resulted in significantly more brain activation when compared with feedback on personalised movement behaviours (P < .001). Activations within regions of the prefrontal cortex were significantly greater for glucose feedback compared with feedback on personalised movement behaviours. Activation in the subgyral area was correlated with moderate-to-vigorous physical activity at follow-up (r=.392, P=.043). In Study Three, time spent on the LibreLink app significantly reduced for G4GPA2 and GPA6 (week 1: 20.2±20 versus week 6: 9.4±14.6min/day, p=.007) and significantly fewer glucose scans were recorded (week 1: 9.2±5.1 versus week 6: 5.9±3.4 scans/day, p=.016). Similarly, Fitbit app usage significantly reduced (week 1: 7.1±3.8 versus week 6: 3.8±2.9min/day p=.003). The number of Fitbit syncs did not change significantly (week 1: 6.9±7.8 versus week 6: 6.5±10.2 syncs/day, p=.752). CONCLUSIONS. Study One highlighted the fact that thus far the field has focused on examining neurological responses to health messages using fMRI for smoking with important knowledge gaps in the neurological evaluation of health messages for other lifestyle behaviours. The prefrontal cortex and amygdala were most commonly activated in response to health messages. Using fMRI, Study Two was able to contribute to the knowledge gaps identified in Study One, with personalised glucose feedback resulting in a greater neurological response than personalised feedback on physical activity and sedentary behaviour. From this, Study Three found that individuals at risk of developing type 2 diabetes were able to engage with digital health technologies offering real-time feedback on behaviour and physiology, with engagement diminishing over time. Overall, this thesis demonstrates the potential for digital health technologies to play a key role in feedback paradigms relating to chronic disease prevention.

Resumo:

Variability affects the performance and power of a circuit. Along with static variations, dynamic variations, which occur during chip operation, necessitate a safety margin. The safety margin makes it difficult to meet the target performance within a limited power budget. This research explores methodologies to minimize the safety margin, thereby improving the energy efficiency of a system. The safety margin can be reduced by either minimizing the variation or adapting to the variation. This research explores three different methods to compensate for variations efficiently. First, post-silicon tuning methods for minimizing variations in 3D ICs are presented. Design methodologies to apply adaptive voltage scaling and adaptive body biasing to 3D ICs and the associated circuit techniques are explored. Second, non-design-intrusive circuit techniques are proposed for adaptation to dynamic variations. This work includes adaptive clock modulation and bias-voltage generation techniques. Third, design-intrusive methods to eliminate the safety margin are proposed. The proposed methodologies can prevent timing-errors in advance with a minimized performance penalty. As a result, the methods presented in this thesis minimize static variations and adapt to dynamic variations, thereby, enabling robust low-power operation of digital systems.

Background: O câncer de colo uterino é um grande problema de saúde pública no Brasil e no mundo. Atinge cerca de meio milhão de mulheres, sendo que 50 % destas morrem. Os métodos visuais, alternativos á citologia e viáveis para países em desenvolvimento, têm sido avaliados mais intensamente na última década. Objetivos: Avaliar o desempenho da Fotografia Cervical Digital (FCD) na detecção do câncer do colo de útero e de suas lesões precursoras. Métodos: 176 mulheres foram avaliadas pelos métodos de Inspeção Visual com ácido acético (VIA), Inspeção Visual com lugol (VILI), Fotografia Cervical Digital com ácido acético (FCDA) e Fotografia Cervical Digital com lugol (FCDL). Destas, 36 foram classificadas pela histologia. Resultados: A concordância entre avaliadores observou valores de Kappa: Fotografia Cervical Digital com ácido acético, K=0,441, e Fotografia Cervical Digital com lugol, K=0,533. A concordância entre as inspeções a olho nu e as fotografias cervicais digitais após a utilização de ácido acético no colo uterino, K=0,559, e a concordância após a utilização da solução de lugol, K=0,507, considerada como concordância moderada em ambos os casos. Das 36 pacientes com avaliações histológicas, 20 dos 25 casos positivos foram corretamente avaliados tanto pela FCDA, como pela FCDL, demonstrando resultados similares aos descritos anteriormente. Conclusão: A FCD é um método promissor para o rastreamento do câncer de colo de útero e suas lesões precursoras, para países em desenvolvimento.
Background: Uterine cervix cancer is a major public health problem in Brazil and in the world. It affects half a million women with a death rate of 50%. The visual, alternative methods to cytology, considered viable for developing countries, are being assessed more intensively in the last decade. Objective: To evaluate the performance of Cervical Digital Photography (CDP) in detecting cervical cancer and its precursory lesions. Methods: A total of 176 women were evaluated by the following methods: Visual Inspection with Acetic Acid (VIA), Visual Inspection with Lugol’s Iodine (VILI), Cervical Digital Photography with Acetic Acid (CDPA) and Cervical Digital Photography with Lugol’s Iodine (CDPL). Among these, 36 were classified by histology. Results: The correlation between evaluators observed Kappa values: Cervical Digital Photography with acetic acid, K = 0.441, and Cervical Digital Photography with Lugol's Iodine, K = 0.533. The correlation between the naked eye and cervical digital photography inspection after using acetic acid in the uterine cervix, K = 0.559, and the correlation after using Lugol's Iodine solution, K = 0.507, were regarded as moderate in both cases. Of the 36 patients with histological evaluation, 20 of the 25 positive cases were correctly assessed both by the CDPA as well as by CDPL, showing similar results than those described previously. Conclusion: CDP is considered a more promising method for screening the uterine cervix cancer and its precursory lesions in developing countries.

Previous research suggests student paramedics are among the professionals at highest risk of post-traumatic stress disorder (PTSD). However, little research has been conducted examining duty-related post-traumatic stress symptoms (PTSS) and clinical levels of PTSD in this poplulation. The current study of 36 student paramedics undertaking university or job-based training is the first longitudinal investigation of PTSS and PTSD in this group.

Educational Psychology
Ph.D.
School safety is one of the most important issues facing administrators, teachers, and parents. Several risk factors have been identified as antecedents to aggression including poor social skills, difficulty dealing with anger and frustration, and inadequate problem solving abilities. No Child Left Behind requires all schools receiving Title IV funds to implement research based violence interventions. Second Step, an internationally recognized violence prevention curriculum published by Committee for Children was implemented in an urban elementary school with 66 African American students in grades 3 through 5 for 9 weeks. This study employed a randomized control group design with two treatment conditions; Second Step instruction and Second Step instruction with digital role-playing, an adaptation of digital storytelling, to increase program effectiveness and intensify student motivation. The School Social Behavior Scales-2 (Merrell, 2002) was used to assess differences in aggression and prosocial skills. MANOVA indicated significant differences for grade only. Older students had higher prosocial behavior scores and younger students had lower scores on the program's content assessment. Results indicated that the Second Step curriculum did not affect behavior. Although the benefits of teaching students to respond empathetically to others, solve problems, and control anger have been documented in the literature, the use of Second Step to accomplish these goals has not been supported.

Dans une société de plus en plus numérisée où les outils et les réseaux sociaux numériques sont largement utilisés par les jeunesses populaires, des « paniques morales » trouvent un nouveau terrain d’application. Naïveté, dangerosité, addiction aux écrans, analphabétisme technologique, recherche de buzz par les bagarres filmées, provocation, obésité : autant de représentations refoulées qui se réactivent. Cette thèse interroge le rapport au numérique des jeunesses populaires et des professionnels socio-éducatifs qui les accompagnent. Réalisée dans un territoire sensible en Île de France, par le biais d’une démarche ethnographique (physique et virtuelle), elle est le fruit de trois ans de travail de terrain (2019-2022) effectués auprès d’une trentaine des professionnels de la Prévention Spécialisée et d’une soixantaine de jeunes, âgés de 12 à 23 ans, accompagnés par des éducatrices et éducateurs de rue. Nous analysons les représentations de ces professionnels sur les pratiques numériques des jeunes, en particulier sur les réseaux sociaux numériques, et les confrontons aux usages numériques de ces derniers. Dans un premier temps, nous faisons le constat de la prégnance dans le secteur d’une vision négative sur les pratiques numériques des jeunes, relevant d’un phénomène que nous qualifions de « panique numérique ». Dans un second temps, nous interrogeons cette « panique numérique » en retraçant la vie numérique des jeunes. Nous montrons que les « jeunesses populaires » utilisent les réseaux sociaux numériques principalement pour s’épanouir et entretenir des liens d’amitié, même si leurs pratiques s’inscrivent dans des rapports sociaux situés. Enfin, nous explorons les différentes pratiques numériques d’un certain nombre de professionnels qui, rejetant la « panique numérique », s’investissent dans l’univers juvénile digital. Les nouvelles sociabilités numériques sont ici vécues comme une « épreuve » qui les invite à actualiser leurs méthodes d’accompagnement et à développer ce que nous appelons une « relation éducative numérisée ». Cette thèse vise à faire la démonstration que les discours traditionnellement pessimistes à l’égard des jeunesses populaires, qui s’ancrent dans une inquiétude envers toute nouvelle pratique culturelle, rejaillissent sur les modes de prise en charge éducative
In an increasingly digitalized society where digital tools and social networks are widely used by popular youth, “moral panics” find a new field of application. Naivety, dangerousness, screen addiction, technological illiteracy, search for buzz through filmed fights, provocation, obesity: as many repressed representations which are being reactivated. This thesis questions the relationship between digital technology and young people in situations of social vulnerability and the socio-educational professionals who accompany them. Carried out in a sensitive territory in Île de France*, through an ethnographic approach (physical and virtual), this thesis is the result of three years of field work (2019-2022) carried out with around thirty professionals in the field of Specialized Prevention and around sixty young people, aged 12 to 23, accompanied by street educators. We analyse the representations of these professionals on the digital practices of young people, in particular regarding digital social networks, and confront them with the digital uses of the former. Firstly, we note the prevalence, in the sector, of negative vision of the digital practices of young people, relating to a phenomenon that we describe as “digital panic”. Secondly, we question this “digital panic” by retracing the digital lives of young people. We underline that “popular online youth” use digital social networks to flourish, develop a cultural practice and above all maintain friendships, even if their digital practices are part of situated social relationships. Finally, we explore the different digital practices of a certain number of professionals who, rejecting “digital panic”, are investing in the juvenile digital world. The new digital sociabilities are experienced here as a “digital test” which invites them to update their guidance methods and to develop what we call a “digitalized educational relationship”. This thesis aims to demonstrate that traditionally pessimistic discourses towards working-class youth, which are rooted in a concern towards any new cultural practice, reflect on the methods of educational support for their digital practices

Programmering inkluderar vanligtvis användningen av en dator och en textredigerare, men ändå avslutas programmeringskurser vid högskolor och universitet ofta med traditionella skriftliga tentor för att bedöma studenternas förvärvade praktiska kunskaper. Denna traditionella examineringsmetod begränsar komplexiteten i programmeringsproblem och kan leda till oavsiktliga subjektiva bedömningar. Tidigare studier om datorbaserade programmeringstentor som efterliknar verkliga programmeringsförhållanden tyder på att bedömningen av studenternas förvärvade kunskaper kan effektiviseras samtidigt som både betygs- och administrationsprocesser förenklas. Vi använder Bunges generella vetenskapliga metod och fallstudiemetodik för att utveckla ett system för datorbaserade programmeringstentor som kan implementeras på KTH Kista. Våra resultat tyder på att programmeringstentor kan utföras säkert på studenternas egna datorer genom att starta datorn i en begränsad förkonfigurerad systemmiljö med blockerad internetåtkomst från ett USBminne. Parat med den öppna lärplattformen Moodle kan tentorna administreras elektroniskt och utformas med automatiska rättningssprocesser. För att hjälpa tentavakter utvecklade vi även ett observationsverktyg som kan upptäcka om den begränsade systemmiljön kringgås. Trots uteblivna verkliga tester av systemet på grund av omständigheterna orsakade av den pågående pandemin, drar vi, med stöd av tidigare studier, slutsatsen att vår föreslagna lösning för datorbaserade programmeringstentor kan förbättra kvaliteten och effektiviteten av programmeringskurser och deras examinationsprocesser.
Programming usually includes the use of a computer and a text editor, yet programming courses given at institutions of higher education often conclude with traditional written exams to assess the students’ acquired practical knowledge. This traditional examination method restricts the complexity of programming problems and may result in unintentional subjective assessments. Previous research on computer-based programming exams that mimic real programming conditions suggest that the assessment of the students’ acquired knowledge can be made more efficient while also simplifying both grading and administration processes. We use Bunge’s general scientific method and case study methodology to develop a system for computer-based programming exams that can be implemented at KTH Kista. Our results suggest that programming exams can be safely performed on the students’ own computers by booting the computer into a restricted preconfigured system environment with blocked Internet access from a usb flash drive. Paired with the open-source learning management system Moodle, the exams can be administered electronically and designed with automatic grading processes. To help exam invigilators we also developed an observation tool that can detect if the restricted system environment is circumvented. Despite the lack of real tests of the system due to the circumstances caused by the ongoing pandemic, we conclude, with the support of previous studies, that our proposed solution for computer-based programming exams can improve the quality and efficiency of programming courses and their examination processes.

Although a multitude of preventative programs have been utilised worldwide to modify cardiovascular risk factors, none have included internet based interventions. Study 1 aimed to compare internet based (n = 21), face-to-face (n = 27), and combined (n = 21) treatment groups with a naturally occurring control group (n = 24) on physiological, psychological, and lifestyle risk variables for cardiovascular disease across 6-months, and to determine if there were relationships between changes in the psychological and physiological variables over time. Results indicated that the internet based group had significantly greater social reciprocity than the face-to-face group. Significant time effects were noted for heart rate, stress, depression, anxiety, reciprocity, anger expression-out, anger expression-in, anger control-out, and anger control-in. Results also demonstrated that increases in reciprocity and anxiety, and decreases in anger expression-out, were related to increases in heart rate. "In contrast, less anger suppression was a significant predictor of greater systolic blood pressure. However, there were no significant results for group, time, or predictive value for the other psychological, physiological, and lifestyle risk variables. A follow-up study examined the effects of unstructured (n = 13) and highly structured (n =14) internet based programs on physiological, psychological, and lifestyle risk variables for coronary heart disease over 6-months. It also investigated if there were relationships between changes in the psychological and physiological variables over time. Participants stages of change were assessed in relation to psychological and lifestyle risk variables. Results showed that the unstructured group scored significantly higher on anger-expression-out than the highly structured group and that the unstructured groups alcohol usage significantly reduced over time. The remaining psychological, physiological and lifestyle risk variables did not produce significant group, time, or predictive changes. The stage of change results indicated no significant group or time effects. Results indicated that greater angry reaction scores were predictive of higher heart rate and increased stress scores were predictive of higher diastolic blood pressure. The critical psychological variables predictive of poorer cardiovascular functioning should be targeted in future interventions.

While today's police forces are decreasing in number and their resources are limited, population is at the same time increasing. This means that other types of efforts and strategies are needed to fight crime. There are different strategies to do this, one of which is called community policing that involves proactive cooperation between citizens and the police to deal with the problems. Traditionally, community policing meant that a local police in the neighbourhood called for physical meetings, where citizens and police together raised problems and discussed solutions to these. With today's limited resources, there is little possibilities for the police to execute this kind of physical collaboration and meetings. On the other hand, another meeting place has been added (the one online) and an alternative way to implement community policing may be online. With digital channels for this purpose, there may also be an opportunity to reach groups of citizens that the police have not reached before, but in order to do so, it requires work and a use of these digital channels in the right way according to community policing. The purpose of this paper is to investigate what challenges and requirements that needs to be taken into consideration when implementing community policing with the support of digital communication channels. For this purpose, qualitative research in the form of literature studies and semi-structured interviews were conducted. Findings show there are a lot of challenges and requirements to consider and there are guidelines in the analysis and discussion section, to help begin to implement this way of working. The practical implications for this thesis may help police improving their relationships with citizens in vulnerable areas to be able to cooperate according to community policing to make these areas a better and safer place to live.

Ein gesundes Alter(n) ist sowohl auf individueller Ebene als auch auf gesellschaftlicher Ebene von großer Relevanz. So wächst die Bedeutung von Prävention und Gesundheitsförderung bis ins hohe Alter – einerseits, um die Autonomie, Selbstbestimmtheit, soziale Teilhabe und Lebensqualität des älteren Menschen aufrecht zu erhalten und andererseits, um den durch den demografischen Wandel bedingten gesundheitspolitischen Herausforderungen begegnen zu können. Dabei weist der gesundheitliche Status im Alter neben hoher Vulnerabilität eine Vielzahl an Ressourcen und somit Ansatzpunkte für präventive und gesundheitsförderliche Interventionen auf. Technische Innovationen bieten hier ein wachsendes Potenzial, um Maßnahmen dieser Art zu stützen. Zur Erschließung des neuartigen Themenfeldes werden die Ergebnisse dreier Einzeluntersuchungen berichtet, in welchen sowohl qualitative als auch quantitative Methoden angewandt werden. Mit Hilfe der Durchführung von Expertinneninterviews werden Bedarf und Potenzial innovativer Technik in Prävention und Gesundheitsförderung für Ältere und erste Anforderungen an eine solche Technik erfasst. Eine innovative Möglichkeit zur Umsetzung präventiver und gesundheitsförderlicher Interventionen bieten digitale Bewegungsspiele. So werden darauffolgend im Rahmen einer quasi-experimentellen Kohortenstudie gesundheitsbezogene Veränderungen durch das Spielen sog. Serious Games im Setting (teil-)stationäres Pflegewohnen evaluiert. Die Ergebnisse zeigen erste gesundheitsförderliche Tendenzen. Innerhalb einer Fokusgruppe werden abschließend drei digitale Bewegungsspielsysteme unter Beachtung zielgruppenspezifischer Bedarfe bewertet und notwendige Ressourcen für den erfolgreichen Einsatz im Anwendungskontext erarbeitet. Um die neugewonnenen Erkenntnisse in nachhaltiger Form nutzbar zu machen, werden diese in einem Anforderungskatalog für die erfolgreiche Implementierung eines digitalen Bewegungsspiels im Kontext der Pflege zusammengefasst.
Being healthy in old age and aging healthily is of great relevance at both the individual and societal level. Thus, the importance of prevention and health promotion even in an old age is growing - on the one hand, to maintain the autonomy, self-determination, social participation and quality of life of the elderly and, on the other hand, to be able to meet the health policy challenges caused by demographic change. Health in old age is not only highly vulnerable but also offers a multitude of resources and starting points for preventive and health-promoting interventions. Technical innovations offer a growing potential to support measures of this kind. In order to open up this new field of research, the results of three individual studies are reported, in which both qualitative and quantitative methods are applied. By conducting expert interviews, the need and potential of innovative technology in prevention and health promotion for the elderly as well as first requirements for such a technology are identified. Digital exercise games offer an innovative possibility for the implementation of preventive and health-promoting interventions. Subsequently, health-related changes caused by playing digital exercise games, so-called serious games, in the setting of nursing care are evaluated within the framework of a quasi-experimental cohort study. The results show first health-promoting tendencies through playing serious games. Last, three digital exercise game systems will be evaluated in a focus group on the basis of the needs of the target group. Additionally, the necessary resources for successful use of such systems in a real application context are developed in a participatory way. In order to make the newly gained knowledge usable in a way that is sustainable and relevant for practical use, it is then summarized in a catalogue of requirements for the successful implementation of a digital exercise game in the nursing environment.

El mantenimiento preventivo de un auto es un procedimiento que permite su correcto funcionamiento, la conservación de su valor y, a la larga, evitar incurrir en mayores gastos. Para realizar este tipo de mantenimiento, en principio se debe tomar en cuenta el kilometraje del auto el cual influye en el tipo de reposiciones a efectuar. Cada 5000 km, deben cambiar el lubricante, filtro de aceite y filtro de aire ; y cada 10,000 km, se realizan las mismas reposiciones y se incluye el cambio de bujías. Muchos conductores no realizan el mantenimiento periódico de su auto lo que les genera mayores gastos y desperfectos que ponen en riesgo no solo al vehículo sino la propia vida del conductor. Utilizando la herramienta Experiment Board se validó que la no realización del mantenimiento de autos representa un verdadero problema para sus propietarios y que una de sus principales causantes es la falta de tiempo de los conductores. Mediante el trabajo de investigación se evaluó la viabilidad de prestar el servicio de mantenimiento de autos express en la comodidad del lugar en el que se encuentre el conductor. El modelo de negocio resultó atractivo porque puso a disposición de los conductores a mecánicos especializados, productos originales y un horario de atención extendido con solo utilizar un aplicativo móvil interactivo. Las herramientas tecnológicas facilitaron el desarrollo de la idea y disminuyeron la necesidad de contar con activos fijos tangibles que retrasan el proceso.
Preventive car maintenance is a procedure that allows its correct functioning, the conservation of its value and, in the long run, avoiding higher expenses. In order to perform this type of maintenance, the mileage of the car must be taken into account first which influences on the type of replacements to be made. Every 5 000 km, lubricant, oil filter and air filter should be changed; and every 10 000 km, the same replacements should be made including spark plugs. Many drivers do not perform the periodic maintenance of their car generating higher expenses and damages that, not only puts vehicles at risk, but also the own drivers life. Using the Experiment Board tool, it was proved that the non-performance of car maintenance represents a real problem for its owners and that one of its main causes is the driver’s lack of time. Through research work, the feasibility of providing the express car maintenance service was evaluated in the comfort of the place where the driver is located. This business model was attractive since it made specialized car mechanics available to drivers, original products and an extended business hours by only using an interactive mobile application. The technological tools facilitated the development of the idea and decreased the need to have tangible fixed assets that delayed the process.

La capacité de l’assurance à produire et distribuer les risques et les responsabilités s’appuie sur l’exploitation de multiples sources de données. La masse d’information produite à l’ère numérique peut être mobilisée pour reconfigurer les relations entre assureurs et assurés. L’assurance comportementale, basée sur la captation et la valorisation de traces laissées par les comportements quotidiens des assurés, en constitue un cas frappant et politiquement clivant, alors même que ces produits sont mal connus. Sur la base d’une enquête qualitative et du déploiement d’une sociologie économique de l’information, cette recherche met en lumière l’origine et le fonctionnement concret de l’assurance comportementale. Elle expose le contexte d’émergence de ces produits ainsi que les modalités de leur conception et de leur mise en œuvre. Si l’exercice de formes de pouvoir par l’assurance est aussi ancien que l’institution elle-même, il apparaît que les modalités de cet exercice par l’assurance comportementale sont inédites. Sur la base de théories de l’économie comportementale et de la mise en place d’un circuit informationnel appuyé par les objets connectés, les porteurs de l’assurance comportementale ambitionnent de conduire numériquement les conduites quotidiennes des assurés, et de se positionner comme chefs d’orchestre de l’alignement des intérêts individuels, entrepreneuriaux et sociétaux. L’assurance comportementale s’apparente ainsi à une tentative inachevée de mise en place d’une gouvernementalité algorithmique
The Insurance’s ability to shape and distribute risks and responsibilities relies on the exploitation of multiple sources of data. The large amount of information produced in the digital era can be mobilized in order to reconfigure the relationship between the insurers and the insureds. Behavioral insurance, which builds on the tracking and valuation of the insured’s daily behavioral data, constitutes a striking and politically sensitive case, even though it is a poorly documented phenomenon. Building on a qualitative investigation and the deployment of an economic sociology of information, this research sheds light on the origins and the concrete functioning of behavioral insurance. The research shows the context of emergence of these products and the ways these are designed and implemented. If the wield of power by insurance is as old as the institution itself, it appears that the forms of this wielding are unprecedented. On the basis of behavioral economics theories and the shaping of an informational pipelines built on the uses of tracking devices, the promoters of behavioral insurance attempt to digitally conduct insured’s daily conducts, and to act as conductors of the alignment of individual, entrepreneurial and societal interests. Behavioral insurance is an uncompleted attempt of shaping an algorithmic governmentality

Critical evaluation of the actions involved in conservation practice reveals that the limitations of traditional approaches for examination and treatment influence decision-making and affect the artefacts’ interpretation and display. Such problems demonstrate the technological needs and underlie the research aims for the development of scientific conservation and practice. This research evaluates the application of digital technology in conservation of antiquities and works of art by proposing alternative digital methodologies for examination, restoration and conservation documentation. Its value is demonstrated by case studies, covering a broad range of artefacts types and a variety of materials. The key elements of the proposed methodology are the following: • Development and application of computational imaging, computer vision and digitization techniques for enhanced examination and visual analysis • Graphical 3d modelling and physical 3d reproduction for interventive treatment • Workflows for digital and conventional conservation documentation This thesis addresses to what extent 3D technologies contribute to conservation objectives, defined as the balance of preservation, investigation and display, considering also the ethical and theoretical aspects.

Digital dermatitis (DD) is a painful skin condition currently considered to be the leading cause of infectious lameness in dairy cattle. The overall objective of this project was to investigate novel and existing methods of detecting DD to be used by farmers and researchers to monitor the disease, and to investigate the impact of farmers’ prevention and treatment strategies on disease prevalence. Visual inspection of lesions in the parlour was found to be a practical and reliable method for detecting and classifying DD. In addition, thermography was identified as a potential tool for the detection of cattle foot disorders. Validating such methods for detecting DD is important because locomotion scoring alone was not found to be sufficiently sensitive to identify cows with DD. In a further study a novel ethogram approach validated several specific behaviours associated with DD. A telephone survey was carried out to establish the nature and scope of management strategies farmers use to control DD. The two main strategies identified in the survey were 1) whole herd footbathing and 2) an individual treatment approach. A one year observational study on fifteen farms used the inspection method developed in the parlour to investigate the impact these two approaches had on disease prevalence. It was found that as herd size increased, footbathing became far less effective in maintaining a low prevalence than treating cows individually. Farmers use a variety of methods in an attempt to control DD on their farms, with different levels of emphasis placed on the priority and regularity of prevention and treatment. An outcome of this study is a DD monitoring approach farmers can use, to routinely assess the effectiveness of prevention and treatment strategies. In addition, results indicate that as herd size and disease prevalence increase, individual treatment is imperative for therapeutic resolution of DD.

A ocorrência de arborescências em água (water tree) ou elétrica (electrical tree) é apontada como o principal fenômeno de degradação em isolações sólidas de cabos de distribuição de energia elétrica. A evolução destas arborescências pode levar a camada de isolação à ruptura dielétrica e, como conseqüência, à falha destes equipamentos, com a interrupção do fornecimento de energia elétrica. O entendimento deste fenômeno é necessário para desenvolver métodos de análise e prevenção da ruptura de materiais isolantes. Este trabalho mostra a aplicação da técnica contraste de fase por raios X como metodologia para o estudo das arborescências formadas em materiais isolantes de borracha de propileno etileno (EPR) e polietileno reticulado (XLPE).
The water tree or electrical tree occurrence is identified as the main phenomena in the degradation in solid isolations of the electric energy distribution cables. The water tree evolution can lead to dielectric breakdown of the isolation layer and, consequently, to the failure this equipment and the interruption of the electric energy supply. The understanding this phenomenon is necessary for the development analysis methods and to prevent collapse in the polymeric insulation. This work demonstrates the application of X-ray phase contrast technique as a methodology for the study of the water tree and electrical tree in Ethylene propylene rubber (EPR) and crosslinked polyethylene (XLPE).

Texto completo da fonte

Resumo:

Tout mouvement humain présente une variabilité inter- et intra-individuelle. Cette variabilité du mouvement (VM) concerne les trajectoires, les coordinations, les forces motrices et les activations musculaires. Pourtant, à ce jour, la VM est quasiment ignorée en conception de postes de travail et il n’existe pas d’outil permettant de la simuler. L’objectif de ces travaux a donc été de développer unhumain virtuel (HV) permettant de simuler les effets d’une source de VM (la fatigue musculaire) sur une tâche de référence (mouvement répétitif de pointage). Un contrôleur d’HV a été développé. Basé sur le modèle de fatigue de Xia et Frey-Law, il implémente des commandes conçues pour simuler certains effets de la fatigue (limitation des efforts, transfert de l’activité motrice, réduction des performances de suivi de trajectoire). L’actionnement de l’HV est calculé par optimisation quadratique à l’aide d’un moteur physiquede simulation dynamique. Des données de mouvement ont été analysées pour identifier la VM induite par la fatigue lors de l’activité de pointage, et valider les commandes d’HV proposées. Une campagne de mesures a été menée en laboratoire. Une analyse en composantes principales (ACP) des données cinématiques a permis d’identifier les degrés de liberté impliqués dans la VM et détecter les transitions d’adaptation du mouvement à la fatigue. Le démonstrateur d’HV restitue certaines caractéristiques de la VM observée.Des améliorations de l’HV sont proposées, mais celui-ci permet déjà de sensibiliser les concepteurs à l’intégration de la VM dans la démarche de prévention dès les premières phases de conception de postes de travail
Every human movement presents an inter- and intra-individual variability. This variability of movement (MV) affects trajectories, coordinations, motor forces as well as muscular activations. However, to date, MV is almost ignored in the workstations design and there is no means to simulate it. The objective of this work was therefore to develop a virtual human (VH) to simulate the effects of one source of VM (muscle fatigue) on a reference task (a repetitive pointing task). A VH controller has been developed. Based on Xia and Frey-Law muscle fatigue model by, it implements controls designed to simulate some effects of muscle fatigue (exertion limitation, transfer of motor activity, reduction of trajectory tracking performance). The actuation of the VH is calculated by quadratic optimization using a dynamic simulation physics engine. Movement data was analyzed to identify fatigue-induced MV during the pointing activity, and to validate the proposed VH controls. An laboratory experiment has been carried out. Principal component analysis (PCA) of kinematic data identified the degrees of freedom involved in the VM and detected transitions of movement patterns with fatigue. This VH demonstrator simulates some characteristics of the MV observed. Improvements of the HV are proposed, however it can already be used to make designers more aware of effects of the VM in occupational risks prevention from the first steps of workstations design

Cette thèse s’articule autour de la conception d’un outil de prévention numérique face aux inondations. Notre travail suit deux objectifs : déterminer les leviers psychologiques permettant d’améliorer l’acceptabilité sociale a priori de l’outil, et évaluer l’efficacité de l’outil une fois sa conception avancée. Nous répondons à ces objectifs grâce à trois études. Dans la première, nous utilisons la Théorie des Buts Cadres afin de déterminer quelle grande motivation est la plus importante – au regard des perceptions du risque et de contrôle – pour améliorer l’acceptabilité de l’application. Nos résultats nous indiquent que la motivation Normative, centrée sur les aspects collectifs, est la plus efficace afin d’amener les individus vers l’outil. De plus, la perception du risque reste un bon prédicteur de l’acceptabilité de l’outil. Ensuite, dans l’objectif de pouvoir mesurer spécifiquement la perception de contrôle des inondations des individus, nous avons procédé à la validation d’une adaptation de l’échelle des Sphères de Contrôle. Nos analyses montrent une structure factorielle correcte en trois facteurs : Contrôle des inondations, Contrôle personnel, Nature contrôlable. Nous pouvons ainsi l’utiliser dans notre dernière étude portant sur l’évaluation de l’outil numérique. Nous mesurons au cours d’une étude pré/post en trois temps (avant – après – 2 semaines après) l’effet de l’outil sur les perceptions du risque et de contrôle des participants. Nous comparons aussi l’outil à une vidéo sur le risque climatique servant de groupe contrôle. Nos résultats indiquent que les connaissances et la perception de contrôle des inondations augmente plus que le groupe contrôle après l’utilisation de l’outil. Cependant, notre étude semble très couteuse, ce qui a pu biaiser nos autres résultats.Cette thèse a permis de comprendre que la Théorie des Buts Cadres – qui n’avait jamais été utilisée dans le champ des risques – peut être un bon prédicteur de l’acceptabilité lorsqu’elle est accompagné de la perception des risques. Ce travail a permis la réalisation d’un encart spécifique au sein de l’outil afin de renforcer leur motivation à utiliser ce dernier. Nous avons également montré que l’outil pouvait améliorer les connaissances des individus ainsi que leurs perceptions des comportements à mettre en place en prévention d’une inondation
This thesis focuses on the design of a digital flood prevention tool. Our work has two objectives: to determine the psychological levers that can be used to improve the tool's a priori social acceptability, and to evaluate the tool's effectiveness once it has been designed. We are meeting these objectives through three studies. In the first, we use Goal Frame Theory to determine which major motivation is the most important - with regard to perceptions of risk and control - for improving the acceptability of the application. Our results show that normative motivation, which focuses on collective aspects, is the most effective in getting individuals to use the tool. Furthermore, the perception of risk remains a good predictor of the tool's acceptability. Next, with the aim of being able to specifically measure individuals' perception of flood control, we validated an adaptation of the Spheres of Control scale. Our analyses show a correct factor structure in three factors: Flood Control, Personal Control, Controllable Nature. We can therefore use it in our latest study on the evaluation of the digital tool. In a three-stage pre/post study (before - after - 2 weeks after), we measure the effect of the tool on participants' perceptions of risk and control. We also compared the tool with a video on climate risk used as a control group. Our results indicate that participants' knowledge and perception of flood control increased more than the control group after using the tool. However, our study appears to be very expensive, which may have biased our other results.This thesis enabled us to understand that Framework Goal Theory - which had never been used in the field of risk - can be a good predictor of acceptability when accompanied by risk perception. This work led to the creation of a specific insert within the tool to reinforce their motivation to use it. We also showed that the tool could improve people's knowledge and perceptions of the behaviours they should adopt to prevent flooding

Resumo:

Background – Inertia describes a state whereby companies develop slower relative the pace of change experienced by their environment, something most organizations experience at least once in their lifetime. Being in the state of inertia and consequently failing to adapt to change cause new businesses to replace old ones. Therefore, it is important for firms to be dynamic, which enables them to quickly recognize opportunities and threats. A way for companies to answer to these changes is to possess dynamic capabilities, which is found to be a solution for inertia. Digital innovation has played a key role in the evolution of dynamic environments. In order for companies to adapt to changing environments, the need for digital adaptation is becoming increasingly crucial. As a result, digital and social platforms have rapidly emerged throughout society, forcing companies to act to avoid stagnating in their development. Purpose - This thesis aims to analyze how the utilization of Facebook as a dynamic capability can prevent inertia through the microscope of the Dynamic Capability Framework. Method - Empirical data was collected through an interview study with employees at strategy and digital media consultancy firms. The participants possess extensive knowledge in the field of strategic implementation of social media. Primary data was gathered through semi-structured interviews and was analyzed in relation to the reviewed theory within inertia, dynamic capabilities, and digital innovation, by a thematic analysis. Findings - The findings of this thesis indicate that by dynamically utilizing Facebook, companies can extensively explore markets. This allows companies to continuously align existing resources by adapting and acting on identified trends within markets. Since these are actions within the Dynamic Capability Framework, a conclusion can be drawn that the usage of Facebook can be a dynamic capability. The usage of Facebook can therefore prevent organizations from entering the state of inertia. The findings further show that in order for the utilization of Facebook to be a dynamic capability, companies must possess extensive user skills and competencies. This research adds to the existing theory of digital media and business development by examining the usage of the social media platform, Facebook, through the lens of the Dynamic Capability Framework.

Dissertação apresentada para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Ciências da Informação e Documentação – Área de Especialização em Arquivística
Esta dissertação tem como objeto de estudo o arquivo da rádio da RTP. Partindo da caracterização organizacional em que o arquivo está inserido, uma empresa de comunicação social onde os conteúdos produzidos são recursos económicos, patrimoniais e culturais, é referida a importância que o seu acervo possui para o património sonoro português e as atuais práticas de preservação. Assim, partindo da questão “Que desafios se colocam na preservação a longo prazo do acervo sonoro do Arquivo da Rádio da RTP?”, procurou-se responder a diversas hipóteses de investigação que englobam os seguintes objetivos: identificar os problemas de preservação dos vários suportes sonoros em formato analógico e digital, destacando os riscos que o acervo enfrenta em termos de obsolescência tanto dos suportes como dos equipamentos; indicar propostas de boas práticas para a conservação preventiva do acervo; indicar estratégias futuras para a preservação do acervo a nível da preservação digital. Devido à diversidade de suportes existentes no acervo do arquivo da rádio, este estudo centrou-se em quatro suportes: os discos de laca de nitrocelulose, as bobines, os DAT e os discos óticos. Para além da sua representatividade no acervo, esta escolha procura analisar duas realidades tecnológicas distintas, o formato analógico e o formato digital. Recorrendo à observação sistemática dos suportes, estes foram analisados segundo parâmetros uniformes: características técnicas, causas de deterioração e problemas de preservação, condições de armazenamento, obsolescência e acesso aos suportes. A recolha e análise dos dados permitiu conhecer os diversos problemas de preservação que afetam a longevidade dos suportes e colocam em causa o seu acesso futuro. Foi possível identificar problemas distintos para cada tipo de suporte e outros que são transversais, como é o caso da obsolescência. Este problema por si só coloca em risco o acesso à informação armazenada nos vários suportes que, conjugada com a questão da falta de equipamentos capazes de os reproduzir e o conhecimento humano necessário para os utilizar, demonstram os riscos que podem advir da dependência tecnológica no acesso à informação. Para colmatar os diversos problemas de preservação do arquivo da rádio, são referidos um conjunto de boas práticas a implementar em dois domínios distintos. No domínio da conservação preventiva são indicados alguns conselhos no que diz respeito às condições ambientais, à limpeza e higienização, ao acondicionamento e ao armazenamento, tanto dos suportes, como dos espaços. A preservação digital é outro domínio em análise, com a identificação de um conjunto de critérios a ter em conta para a construção e implementação de uma política de preservação digital no arquivo da rádio.

Resumo:

At today's manufacturers, reactive maintenance mostly takes place instead of prevention. At the same time, maintenance is seen as a necessary evil and many companies have no direct strategies or goals for maintenance. In today's maintenance, Industry 4.0 with digitalisation has begun research in and new methods and ideas are produced for more efficient maintenance. The purpose of this study is: To increase the knowledge of how manufacturers can understand and develop a strategy to achieve preventive maintenance and at the same time find essential elements for maintenance digitalisation. Through a literature study, the existing research in prevention and digitalisation in maintenance was studied. To supplement, a single-case study was also conducted that included interviews from a manufacturing company that has reactive maintenance. Two focus groups were also conducted, one on the case company but also on another manufacturing company to compare the answers to the theory. The study shows that there are several root causes that cause manufacturers to remain in reactive efforts in maintenance and it can be difficult to get out. This creates expensive costs for the manufacturer and stress for the maintenance operators. To get out and move towards more prevention, it is important to start with the basics, which is to have a strategy that has been jointly agreed within the organisation. Therefore, it is also important with training and choosing the right kind of maintenance depending on the machine and complexity. The last research question is more complex and it turned out that there are factors in digitalisation where manufacturing companies with reactive maintenance develop and use. By understanding the causes and seeing elements to deal with preventive maintenance, manufacturers can practically use the study to achieve their maintenance goals. Regarding digitization, it is a step further and try to see if it is practical to implement at a company with reactive maintenance. The study only covered information about a specific machine that is the base for generalisation within the case company factory plant. At the same time, the study focused only on the step between reactive and preventive maintenance in order to delimit the theoretical part.

High-risk alcohol consumption remains a primary public health concern for students on college campuses. In response to this concern the National Advisory Council of the National Institute on Alcohol Abuse and Alcoholism created a task force to identify and recommend strategies to aid college administrators in implementing effective alcohol programming at their institutions. While most administrators report being aware of these recommendations, many have not successfully implemented empirically supported interventions on their campuses. One significant barrier is the cost and difficulty of training and hiring skilled staff to implement these interventions. Of the strategies identified as effective, challenging alcohol expectancies is the only strategy validated for group administration with college students and has significant potential to address this remaining barrier. However, current expectancy-based interventions still require highly trained expert facilitators for implementation. The present study aimed to convert the previously validated Expectancy Challenge Alcohol Literacy Curriculum (ECALC) into a digital format amenable to non-expert facilitation. The resulting digital ECALC was implemented in 48 class sections of a first year student course in a group randomized trial. It was hypothesized that receiving the digital ECALC would result in significant changes in alcohol expectancies and subsequent changes in alcohol use and related harms. Analyses revealed significant changes in both positive and negative expectancies following the digital ECALC, however no significant changes in alcohol consumption or alcohol-related harms were observed at a 30 day follow-up. Exploratory subgroup analyses revealed significant differences between experimental and control groups on average and peak drinks per sitting for classes receiving the digital ECALC during the fall semester only. Semester specific variables, environmental context, and social influence variables may have contributed to the lack of behavioral changes in the overall sample following observed expectancy changes. This study represents an important development in expectancy-based interventions for college students as the digital format removed the need for an expert facilitator and maintained significant changes in expectancies. Future studies should focus on replication of these expectancy changes and on demonstrating subsequent changes in alcohol use and related harms. The present study also represents the first evaluation of a group-administered expectancy intervention to report on intra-class correlations which will aid future researchers in designing sufficiently powered studies going forward.

Digital diseases worries livestock industry and arouse interest in extensionists because of the economic losses and difficult control. Losses come from decrease in productive and reproductive performance and, in some cases, the premature culling of high value breeding animals. Besides these, lameness causes negative impact on animal welfare. Digital diseases assume different characteristics in distinct production systems, requiring specific solutions that fits each farms condition. Innovative treatments have been discussed, but are not always economically viable, however, in last years in Veterinary Medicine has increased the interest on the possibility of applying cell therapy in the treatment of diseases related to the locomotor systems, including digital diseases. In the equine, it has been studied its use in the repair of tendineous, articular and osseous lesions, and the perspective of application in other important diseases like laminitis. Considering the importance of digital diseases, especially laminitis, for cattle, cell therapy can represent an additional option for treatment. This study evaluated the development of digital lesions in cattle intensively managed and its response to the treatment with bone marrow mononuclear cells. Were used 15 animals, male, cross-bred (Bos taurus X Bos indicus), healthy, aging about 12 months and with average weight of151,6 ± 24,65 kg, divided in two groups (GT, n=7, GC, n=8). The study was developed in three stages divided in evaluation moments. On first stage, on second month of confinement, after adjustment of management over concrete floor and feeding of corn silage and concentrate, hooves were trimmed and started evaluation of digital disease wich extended to the tenth month. At this time, were observed digital lesions that developed in the period, their influence over behavior and was conducted radiographic examinations trying to establish relationship between external and internal lesions of digits. After ten months of study all animals had its hooves trimmed and all digital lesions, in decorrence of management, were surgically treated. At this time, started last stage in wich animals received cell therapy. To obtain material needed for the protocol, were harvested samples of bone marrow from animals belonging to treatment group (GT). After this, mononuclear cells were isolated and samples were injected at jugular vein. In the protocol for bone marrow harvest and isolation of mononuclear cells was used Ficoll-Paque. On animals from control group (GC), their lesions were treated during hoof trimming, but all anials were evaluated at twelfth month. To certify the effect of cell therapy, besides clinical examination, identification of possible recidivance or new lesions, were done histological examination for occurrence of hyperemia, hemorrhages or edema on dermis, presence of white blood cells inside or outside vessels and necrosis of basal cells from epidermis, and radiographic examination. On direct inspection were observed expressive occurrence of digital lesions like heel horn erosion, haematoma and erosions of sole and white line disease, however with no difference between groups. Major changes in behavior observed along time were decrease in eating time and increase in times lying down and in leisure. Radiographic evaluation didn´t show signs of distal phalanx rotation suggesting external alterations may not be related to internal alterations. Protocols for bone marrow aspiration and for cell isolation using Ficoll-Paque were effective, resulting in obtainance of mononuclear cells with satisfatory viability. But, since it wasn´t observed significative differences between groups related to digital lesions, histological and radiographical examinations, the reoccurrence and appearance of new lesions after cell therapy cannot be related to this treatment, because seem to be more related to management conditions. It can be concluded that applying of bone marrow derived mononuclear cells at jugular vein didn´t show benefits as auxiliary treatment of digital lesions in cattle. The control of risk factors and site of cell application seem to explain the apparent failure of the therapeutic protocol used.
As doenças digitais causam preocupação ao setor produtivo e despertam grande interesse nos técnicos ligados à bovinocultura em função do impacto econômico e do difícil controle. Os prejuízos decorrem de queda no desempenho produtivo, reprodutivo, tratamento oneroso e em alguns casos descarte prematuro de animais de alto mérito genético. Além disso, ameaçam seriamente o bem estar animal. Essas doenças assumem características distintas nos diversos sistemas de produção, o que em alguns casos demandam soluções específicas e tratamentos que atendam a realidade do criatório. Tratamentos inovadores têm sido discutidos, mas nem sempre são viáveis economicamente. Contudo, nos últimos anos, na Medicina Veterinária cresce o interesse na possibilidade de se empregar a terapia celular, que poderia ser aplicada como auxiliar no tratamento de várias enfermidades do aparelho locomotor, incluindo as enfermidades digitais. Em equinos, já se tem investigado seu emprego no reparo de lesões tendíneas, articulares e ósseas, havendo ainda a perspectiva de aplicação em outras doenças importantes como a laminite. Portanto, considerando a importância que as doenças digitais, em especial a laminite, assumem na espécie bovina, a terapia celular pode representar uma ferramenta adicional no tratamento. Esta pesquisa objetivou avaliar o desenvolvimento de lesões digitais em bovinos manejados intensivamente e sua resposta ao tratamento com células mononucleares da medula óssea. Foram empregados 15 bovinos machos, mestiços (Bos taurus X Bos indicus), hígidos com idade inicial aproximada de 12 meses e peso corporal médio de 151,6 ± 24,65 kg, alocados em dois grupos (Grupo tratamento, GT, n=7; Grupo controle, GC, n=8). O estudo foi desenvolvido em três etapas divididos em momentos de avaliação. Na primeira etapa, no 2o mês de confinamento após ajustar o manejo em piso de concreto e a alimentação a base de silagem de milho e concentrado, realizou-se ajuste nas medidas digitais dos animais e iniciou-se o acompanhamento para avaliar a ocorrência de doenças digitais, que se estendeu até o décimo mês. Nesse período, foram realizadas avaliações para diagnosticar as enfermidades que eventualmente surgissem. Estudou-se a influência delas sobre o comportamento diário dos bovinos e procedeu-se a análise macroscópica das lesões digitais e a avaliação radiográfica para se tentar estabelecer uma relação entre as lesões externas e internas dos dígitos. Após dez meses de confinamento, todos os animais tiveram as medidas digitais novamente ajustadas e as enfermidades digitais que surgiram na etapa anterior, em decorrência do manejo, foram tratadas cirurgicamente. Nesse momento iniciou-se a ultima etapa na qual os animais receberam a terapia celular. Para se obter o material necessário que o protocolo exigia colheu-se medula óssea dos bovinos pertencentes ao grupo tratamento (GT), na sequência, as células mononucleares foram isoladas e uma amostra destas foram aplicadas pela veia jugular em cada animal. No protocolo de colheita da medula óssea e isolamento celular empregou-se o Ficoll-Paque®. O grupo controle (GC) foi apenas submetido ao tratamento das lesões e tiveram as medidas dos cascos ajustadas, mas os bovinos de ambos os grupos foram reavaliados ao final do 12o mês do estudo. Para certificar o efeito da terapia celular, além do exame clínico, identificação de possível recrudescimento ou surgimento de novas lesões, realizou-se exame radiográfico, avaliação histológica da região coronária para avaliar presença de hiperemia, hemorragia ou edema da derme, presença de células brancas dentro ou fora dos vasos e necrose de células basais da epiderme. Na avaliação macroscópica foi observada ocorrência expressiva de lesões digitais como erosão de talão, hematoma e erosão de sola e lesão de linha branca, porém, sem diferenças entre grupos. As principais alterações de comportamento observadas ao longo das avaliações foram a redução no tempo de alimentação e aumento nos tempos em ócio e em decúbito, mas, sem diferenças entre grupos tratamento e controle. A avaliação radiográfica não mostrou ter ocorrido a rotação da falange distal indicando que as lesões externas podem não ter relação com as alterações internas. Os resultados obtidos indicam que o protocolo de aspiração de medula óssea e de isolamento celular usando Ficoll-Paque® foi eficaz, resultando na obtenção de células mononucleares com rendimento e viabilidade satisfatórios. Mas, como não foram observadas diferenças significativas entre grupos, tanto com relação as enfermidades como em relação aos resultados histológicos e radiográficos as recidivas ou o aparecimento de novas lesões após a terapia celular não podem ser imputadas a esse tratamento, pois parecem ter relação com o manejo. Conclui-se que a aplicação de células mononucleares da medula óssea pela veia jugular não apresentou benefícios no tratamento auxiliar de lesões digitais em bovinos, sendo que aspectos relacionados ao controle dos fatores de risco e local de aplicação das células parecem explicar a aparente falta de sucesso do protocolo terapêutico empregado.

L'objectif principal de ce travail de thèse est de discuter de la place de la tablette tactile dans un dispositif d'enseignement adapté et ciblé auprès d'enfants détectés à risque de difficultés ultérieures en lecture. Pour répondre à cet objectif et après avoir étayé notre propos avec les résultats de la littérature scientifique, deux axes sont présentés. Un axe expérimental, composé de trois études, nous a permis de mesurer l’impact d’un entrainement spécifique intensif et individuel, via la tablette tactile, sur les performances en identification de mots écrits d’élèves de GSM et de CP faibles (pré)lecteurs. Plus précisément, les résultats du suivi longitudinal des élèves susmentionnés à court et moyen termes semblent aller en faveur d’une amélioration de la conscience phonologique et du traitement grapho-syllabique. Le second axe s’attachait à mettre en lumière l’importance des critères ergonomiques de développement de deux applications ludo-éducatives. Les résultats des évaluations subjectives permettent d’identifier les points nécessitant un travail supplémentaire, ces points pouvant entraver le traitement d’informations cruciales pour l’apprentissage de la lecture
The main objective of this thesis work is to discuss the place of the touch-screen tablet in an adapted and targeted teaching system with children detected at risk of subsequent difficulties in reading. To meet this objective, we have presented two main axes, based on the results of the scientific literature. An experimental axis, made up of three studies, allowed us to measure the impact of a specific intensive and individual training, via the touch-screen tablet, on the performances in written words identification of poor (pre)readers in Kindergarten and First Grade. More precisely, the results of the longitudinal follow-up of the aforementioned students seem to be in favor of an improvement of the phonological awareness and the grapho-syllabic treatment. The second axis aims to highlight the importance of ergonomic criteria for the development of two edutainment apps. The results of the subjective evaluations identify points that requiring additional work, which may hinder the processing of crucial information for the learning of reading

Introducción: La sociedad de la información plantea nuevas formas de vida, trabajo e interrelaciones, exigiendo un constante esfuerzo de Alfabetización Digital. Los Objetivos de Desarrollo de la Declaración del Milenio (United Nations, 2000), promueven la utilización de las tecnologías de información y comunicaciones (TIC) para facilitar el acceso a los conocimientos médicos, fortalecer la investigación y la prevención en salud. En 1993, la Fundación Open Society Institute (OIS) promueve Open Access Initiative (OAI) al objeto de crear sistemas que permiten acceso libre y gratuito a la información científica bajo el compromiso de respeto y fines éticos de utilización, garantizando la calidad de los contenidos sin obligatoriedad de cesión del copyrigth de los artículos. En 2004 Budapest Open Access Initiative (BOAI) desarrolla Directory of Open Accesss Journals (DOAJ) y surgen otras plataformas Open Access (OA). Objetivo: Conocer y analizar el impacto de la OAI sobre la producción científica en Ciencias de la Salud (CS). Método: Descripción y análisis crítico del proceso y principales herramientas OA. Desarrollar herramientas que faciliten el acceso y la difusión del conocimiento en CS generado en España. Estudiar la integración de herramientas 2.0 en revistas OA y de acceso restringido. Resultados: OAI constituye una herramienta importante para la difusión y acceso al conocimiento científico, favoreciendo el incremento de la calidad, visibilidad y prestigio de las publicaciones. SciElo ha permitido incrementar el índice de inmediatez y el Factor de Impacto (IF) de sus revistas, además, SciELO España e IBECS han supuesto un fuerte empuje de visibilidad nacional e internacional de las publicaciones de ciencias de la salud españolas, este último, al utilizar MeSH-DeCS como herramienta de búsqueda al igual que las bases de datos bibliográficas internacionales MEDLINE y LILACS. Conclusiones: Las principales plataformas OA (DOAJ, PLoS, PUBMED, BioMed Central y SciELO) dan acceso a un importante número de publicaciones con IF-ISI reconocido y permiten incrementar su índice de inmediatez y su IF-ISI. Gran parte de publicaciones OA incorporan alguna herramienta 2.0. La sociedad de la información puede ayudar a incrementar el nivel de desarrollo de muchos países en vías de desarrollo pero también puede incrementar la brecha digital en países que no tienen fácil acceso a las TIC. La necesidad constante de alfabetización digital por parte del individuo, supone el riesgo de nuevo de analfabetización de una parte de la población general y de la comunidad científica que se pueda quedar al margen de la integración.

O estudo foi realizado em 12 propriedades, sendo que em todas foi realizado o estudo epidemiológico e em nove o estudo epidemiológico e exame clínico dos animais. Nos centros de manejo foram observados fatores favoráveis a traumatismos nos dígitos dos bovinos, como piso das seringas calçado com pedras, troncos com exposição de ferragens e rampas dos embarcadores com pisos de pedras pontiagudas, além da falta de manutenção e erros estruturais. Em todas as fazendas observou-se um manejo inadequado dos animais. Em 91,7% das fazendas (11/12) havia piquetes com presença de troncos de árvores e 66,7% (8/12) apresentavam áreas de relevo inclinado com presença de pedras; em 16,7% (2/12) das fazendas havia áreas de brejo com áreas alagadas. A sodomia foi relatada em todas as propriedades. Nenhuma fazenda adotava medidas profiláticas relacionadas às afecções podais. Foram examinados 498 bovinos entre fêmeas e machos. Os membros pélvicos foram mais acometidos, tanto nas fêmeas quanto nos machos. Foram diagnosticadas 629 lesões nas fêmeas, sendo as mais frequentes pododermatite séptica, deformações ungulares, pododermatite da sobreunha e dermatite digital. Nos machos diagnosticou-se 285 lesões e as mais frequentes foram pododermatite séptica, deformações ungulares e erosão de talão. Conclui-se que erros de manejo associados às condições inadequadas das instalações foram fatores que contribuíram para a ocorrência de enfermidades podais em bovinos de corte nas fazendas estudadas; as características ambientais favoreceram o desenvolvimento das lesões; as associações de lesões foram mais prevalentes do que as simples, sendo diagnosticadas em animais em todas as fazendas estudadas; o diagnóstico precoce a campo não é realizado, o que contribuiu para aumentar a gravidade e a diversificação das afecções podais diagnosticadas.
The epidemiological study was conducted in 12 properties with the history of foot diseases occurrence and the clinical examination of the affected animals for the diagnosis of foot diseases was performed only in nine of these properties. It was found on the management centers multiple risk factors for digits injuries, as syringes floors paved with rocks, working chutes with iron fittings exposure, loading ramps covered by sharp stones and the lack of maintenance and structural errors. In every farm there was an inappropriate handling of animals. In 91.7% of farms (11/12) there were pickets with trunks of trees and 66.7% (8/12) had areas of sloping relief with stones. Moreover, 16.7% (2/12) of the farms had marsh areas and wetlands. Sodomy was reported in all properties. None of the farms adopted preventive measures related to foot problems. 498 cattle between males and females were examined. The hind limbs were the most affected both in females and in males. 629 lesions were diagnosed in females. The septic pododermatitis was the most common, followed by claw deformities, pododermatitis in the paradigits and digital dermatitis. Between the examined males 285 injuries were diagnosed and the most common were septic pododermatitis, claw deformities and heel erosion. It was concluded that management errors associated with inadequate facilities were factors that contributed to the occurrence of foot diseases in beef cattle in the studied farms. The environmental characteristics favored the development of lesions; combined injuries were more prevalent than the simple ones, being diagnosed in animals in all studied farms; and the early diagnosis was not carried out in the field, which helped to increase the severity and the diversification of the diagnosed foot problems.

Idag finns det inte tillräckligt underhåll på de 15 svamp- och bakterietankar som finns på AstraZenecas vattenreningsverk i Gärtuna, Södertälje. Företaget använder sig av avhjälpande underhåll där de väntar på att tankarna ska gå sönder för att sedan laga dem. Reningsverket vill skapa en underhållsstrategi på tankarna genom att ta reda på om livslängden kan förlängas eller om, och i så fall när, utrustningen behöver renoveras, uppgraderas eller bytas ut. I litteraturstudier undersöktes underhållsstrategier, vattenreningsverk och olika tillståndskontroller. Besök gjordes för att få en bättre uppfattning om hur arbetet på vattenreningsverket ser ut idag. Intervjuer hölls med chefen för vattenreningsverket, en erfaren drifttekniker samt två externa företag som jobbar med underhåll. I resultatet framgår information om vilka fel som uppstått, vilka åtgärder som vidtagits samt vad det kostat. Det framgår även hur underhåll kan ske med olika externa parter och kostnader för detta. Två olika tillståndskontroller, digital röntgenskanning och penetrantprovning föreslås för att upptäcka fel på tankarna. Efter analys av resultatet har slutsatser om en ny underhållsstrategi kunnat dras. Rekommendationer om hur den kan implementeras och lämpligt intervall har tagits fram. AstraZeneca föreslås gå från ett avhjälpande till ett schemalagt tillståndsbaserat underhåll, där tillståndskontroller utförs var tredje, fjärde eller femte år beroende på personalens bedömning och de rekommenderas också att använda sig av externa resurser när det kommer till tvättning och tillståndskontroller av tankarna. Avhjälpande underhåll är omöjligt att planera och kommer med vår lösning att minimeras. Schemalagt tillståndsbaserat underhåll som vi rekommenderar kommer resultera i en mycket enklare planering och oväntade kostnader likväl som oväntade stopptider kommer undvikas. Regelbundet underhåll kommer troligtvis resultera i att tankarnas livslängd ökar vilket bidrar till en bättre hållbarhet och man slipper köpa in nya tankar.
Today, there is not enough maintenance on the 15 fungal and bacterial tanks found at AstraZeneca's wastewater treatment plant in Gärtuna, Södertälje. The company uses a maintenance strategy where they wait for the tanks to fail and then fix them. The treatment plant wants to create a maintenance strategy for the tanks by finding out if the life span can be extended or if, and if so, when the equipment needs to be renovated, upgraded, or replaced. With literature studies maintenance strategies, wastewater treatment plants and various condition investigations, were analysed. The visits were made to get a better idea of how the work at the wastewater treatment plant looks like today. Interviews were held with the head of the water treatment plant, an experienced operating technician and two external companies working on maintenance. The result shows information about what errors occurred, what measures were taken and what it cost. It also shows how maintenance can be done with various external sources and costs for this. Two different condition investigations, digital x-ray scanning and penetrant testing are suggested to detect errors in the tanks. After analysing the results, conclusions about a new maintenance strategy could be drawn. Recommendations on how it can be implemented, and an appropriate interval have been developed. AstraZeneca should go from corrective to scheduled condition-based maintenance, where condition investigations are performed every three, four or five years depending on the staff's assessment and they could make use of external sources when it comes to washing and condition investigations of the tanks. Corrective maintenance is impossible to plan and our solution will minimize this. Scheduled condition-based maintenance that we recommend will result in a much simpler planning where unexpected costs as well as unexpected downtime will be avoided. Regular maintenance will probably result in an increase in the service life of the tanks, which contributes to better durability and they will not have to buy new tanks.

Digital microfluidic biochips (DMFBs) play an important role in the healthcare industry due to its advantages such as low-cost, portability, and efficiency. According to the recent market report, the growth of biochips market is twice than before. However, as the enormous business opportunities grow, piracy attacks, which are exploited by unscrupulous people to gain illegal profits, become a severe threat to DMFBs. To prevent piracy attacks, the conventional approach uses secret keys to perform authentication. Nevertheless, DMFBs only consist of electrodes to control the operations of droplets, and there are no memories and logic gates integrated on it to store secret keys. This makes designing secure defenses of DMFBs against piracy attacks more dicult. Thus, in this thesis, we propose the first authentication method for piracy prevention of DMFBs based on a novel Physical Unclonable Function (PUF). The proposed PUF utilizes the inherent variation of electrodes on DMFBs to generate secret keys, so it does not require memory. Experimental results demonstrate the feasibility of our proposed PUF. Finally, we analyze the security of the proposed method against piracy attacks.

Counterfeit is one of the major crimes in financial market. The objective of this project was to develop a bill-counterfeit prevention (BCP) algorithm used in multi-function peripherals (MFPs) that automatically detects reproduction of U.S. banknotes. Our BCP algorithm includes: (1) complex background removal; (2) banknote location identification; (3) orientation correction; (4) area measurement; (5) front/back identification; (6) treasury seal analysis; (7) upside/down correction; (8) signature analysis; and (9) currency value analysis. To test our BCP algorithm, a database of 132 digital images with various amounts, i.e., $1, $5, $10, $20, $50, and $100, of U.S. banknotes were collected. In this preliminary study, our technique has achieved a detection rate of 78.3% in U.S. banknotes. In summary, our technique can be potentially used in detecting banknote reproduction such that extra enforcement measures (e.g., no scanning or printing, watermark & tracing system, etc.) can be achieved. Future investigation will also include hardware implementation adopting the BCP algorithm used in MFP copiers, scanners and/or printers.

Many investigations focus on the topics of global survey of software, industry competitive forces and economic profit to look into the digital piracy issue. In this thesis, the situational piracy prevention perspective is applied to find out in five different prevention strategies and the role of social sanction and self sanction affect individual digital piracy decision making process. Furthermore, the social sanction is proposed from five situational piracy prevention strategies: (1) increase the effort, (2) increase the risks, (3) reduce the rewards, (4) reduce provocations, (5) remove excuses. This study took the college students in Taiwan as the research objects, totally 1699 valid samples are used for analysis using structural equation modeling (SEM).The results shows that the awareness of the dilemma may positively impact the judgment toward digital piracy, and both situational awareness, and situational projection awareness may negatively impact the judgment toward digital piracy. Moral self efficacy may negatively impact the piracy intention in five different scenarios. Individual digital piracy decision making is influenced by five different kinds of social sanctions, especially in the social sanction of increase the effort, increase the risks, and reduce provocations may negatively impact the piracy intention.These findings have implications for both research and practices.

A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity to interfere with radio frequency systems and services. The apparatus requires only digital logic devices, rather than the analog devices required for frequency- or phase-modulated spread spectrum clock generators. The method provides the opportunity to synchronously demodulate the clock, thus restoring the original narrow band clock signal where required. The apparatus was implemented in a programmable gate array using 20 MHz and 33.33 MHz fundamental clocks. Measurements of the resulting electronic spectra and clock jitter are reported.

According to the fire case statistics within the last decade, building fire occupies the major ones; and among them, the independent residential fires ranks the no. 1. Taking 2016 as the example, independent residential fire can be accounted to be 43.2%, with 58% of death for 98 as the highest casualties. Housing complexes always have janitors, who can inform the fire units once if with fire alarms or with fastest proper treatment right away. However, there’s no such arrangement of personnel for independent houses; which means the fire alarm function nothing if without capable adults in the house for the appropriate method. According to statistics, approximately half of death by fire occurs among residents in independent houses; later recognition of the fire, sick persons, young children, and aged residents, are the major victims. In addition, the loss of property caused by fire is another high cost of society. General function of fire alarm is triggered by alarm speaker (horn); shortage of judgment, physical strength, or other specified conditions during alarm, the function still doesn’t work but generates casualties by life or property. Considering above mentioned, corresponding strategies by integrating Internet of Things (IOT) and fire alarm is recommended; which exchanges the speakers to GSM module for scenario controlled by Arduino for announcing the fire through phone-voice message with higher possibility to rescue those unable persons during the fire, and the direct and accurate notice to the fire rescue unit staffs. Research results confirm the efficacy on contacting the relevant personnel with alert for making up the shortages of fire alarm for independent houses. This research only constructs one main function of the basic system, which suggest the mobile phone APP with connection to digital disaster prevention system with related settings directly, ex. setting up related people, no. of contacts, or even linkage to security system or direct notice to police and fire units for perfect system as well as security of lives and properties. Keywords: Digital Disaster Prevention, Fire Alarm, IOT, GSM

Purpose: The purpose of this paper is to identify the factors influencing the citizens of India to prevent cybercrimes in the proposed Smart Cities of India. Design/methodology/approach: A conceptual model has been developed for identifying factors preventing cybercrimes. The conceptual model was validated empirically with a sample size of 315 participants from India. Data were analyzed using structural equation modeling with SPSS and AMOS softwares. Findings: The study reveals that the “awareness of cybercrimes” significantly influences the actual usage of technology to prevent cybercrimes in Smart Cities of India. The study reveals that government initiative (GI) and legal awareness are less influential in spreading of the awareness of cybercrimes (AOC) to the citizens of the proposed smart cities. Research limitations/implications: The conceptual model utilizes two constructs from the technology adoption model, namely, perceived usefulness and ease of use. The study employs other factors such as social media, word of mouth, GIs, legal awareness and organizations constituting entities spreading awareness from different related literature works. Thereby, a comprehensive theoretical conceptual model has been proposed which helps to identify the factors that may help in preventing cybercrimes. Practical implications: This study provides an insight to the policy maker to understand several factors influencing the AOC of the citizens of the proposed Smart Cities of India for the prevention of cybercrimes. Originality/value: There are few existing studies analyzing the effect of AOC to mitigate cybercrimes. Thus, this study offers a novel contribution.

Resumo:

This thesis describes the design of a baseband digital predistortion architecture for radio frequency (RF) amplifier linearization. Existing amplifier linearization techniques are first examined. The nonlinearity of an amplifier can be characterized as amplitude-to-amplitude distortion and amplitude-to-phase distortion. The distortion can be corrected by providing a predistorted driver signal (both in amplitude and phase) to the amplifier. This counteracts the nonlinearity of the amplifier so that the overall system is more linear. A pipelined predistortion architecture is designed to allow fast processing speed, and is capable of providing linearization for a bandwidth of 25 Mhz. The simulation results show significant improvement in amplifier's performance using predistortion technique. The system bandwidth versus cost is examined by using commercially available components.

This study aims to investigate the effects of different instruction strategies and learning styles on sixth-graders’ learning performance, learning motivation and learning satisfaction toward earthquake disaster prevention learning. There are 113 sixth-graders participated in the experimental activity during the three-week experiment, with a total of 240 minutes. This study employed a quasi-experimental research design. The independent variables are “instruction strategy”, including reflective instruction and expert modeling, and “learning styles”, including concrete experience and abstract conceptualization. The dependent variables are “learning performance of earthquake disaster prevention learning”, “learning motivation toward earthquake disaster prevention learning” and “learning satisfaction toward earthquake disaster prevention learning”. The results revealed that (a) inquiry-based digital gaming significantly facilitated learners’ performance progress of earthquake disaster prevention learning; the abstract conceptualization learners in the reflective instruction group had significantly better learning progress and concepts applying progress of earthquake disaster prevention learning than those who were in the expert modeling group, (b) inquiry-based digital gaming had positive impacts on learning motivation of earthquake disaster prevention learning; the learners of the reflective instruction group held significantly more positive impacts on performance goal than those who were in the expert modeling group, and the learners of the expert modeling group held significantly better positive impacts on active learning strategies than those who were in the reflective instruction group, and (c) inquiry-based digital gaming had positive impacts on learners’ satisfaction toward the earthquake disaster prevention learning.

Taiwan is located in a high-risk area of natural disasters. Due to climate change, the frequency and intensity of natural disasters have increased. How to prevent and mitigate disasters has become one of the important issues for the country to achieve sustainable development goals. However, Taiwan has not in-tegrated digital learning web pages of various disaster prevention knowledge. In contrast, those advanced countries that are much more vulnerable to natural disasters, located in the Pacific Rim seismic zone, like Japan, the United States, Canada, New Zealand, Australia, etc., have applied information technology and multimedia to integrate the knowledge of disaster prevention, response, recov-ery and reconstruction in order to achieve the goals like instant sharing and in-teraction of disaster information, digital learning, historical materials collection, disaster prevention, and disaster reduction. Based on the four functions, exhibition, collection, education, and research, advocated by traditional museums, the study refers high quality disaster preven-tion web pages of developed countries located in the Pacific Rim seismic zone and attempts to plan a systematic digital museum prototype of natural disaster prevention knowledge and education to bridge the gap of the integration of digi-tal disaster prevention education. The planned disaster prevention digital mu-seum prototype contains four major networks: disaster prevention knowledge learning, disaster prevention community, and rehabilitation and reconstruction learning. Due to an overwhelming lack of study data in Taiwan, therefore, it has be-come the first study to explore the topic of building natural disaster prevention digital museums. This study uses the methods of document analysis, case studies, and expert interviews. Based on the results, the study offers suggestions for building a disaster prevention museum prototype in the future.
