Pełny tekst źródłaVarje år dör många nyfödda barn i hjärtproblem, sepsis och nekrotiserande enterokolit. Att ställadiagnos innan kliniska symptom är uppenbara är fortfarande mycket svårt, trots effektiv övervakningoch screening inom intensivvården. Med hjälp av kontinuerlig hjärtövervakning med hjälp HeROsystemetkan kan risken för sepsis beräknas. Förekomsten av särskilda förändringar i barnets andningsmönster (apné, bradykardi och desaturation - ABD) kan användas som en tidig fysiomarkörför sepsis och fungerar därför som en varningssignal. I nyligen presenterade studier har detta visatsminska dödligheten på neontalavdelningar. Dessa ABD-händelser har fram till nu upptäckts genomenkel tröskelnivåbedömning. Baserat på hjärt- och andningsövervakningsdata och kunskap om tidigarepatienter, vill vi förbättra detta system för tidiga varningssignaler genom att använda maskininlärningsalgoritmer. Analys av högfrekvensdata och biomarkörer kvarstår att göra, men ävenbaserat på lågfrekvensdata kunde vi uppnå en specificitet på 70% och en sensitivitet på 65%. Dennarapport sammanfattar den teoretiska bakgrunden till analysmetoden och diskuterar praktiska frågorsom identiferats under arbetets gång.

Pełny tekst źródłaYellow warning signs are an important and abundant type of traffic control device. Improving warning signs could be a cost-effective countermeasure at hazardous locations, especially rural locations where approximately 61% of the Nation's traffic fatalities occur. The use of fluorescent yellow sheeting in place of standard yellow sheeting provides a method to increase the conspicuity of the traffic sign while conforming to the guidelines specified by the Manual of Uniform Traffic Control Devices. The 3M Corporation, and later other companies, developed a long-lasting fluorescent yellow retroreflective sign. Although the properties of the fluorescent yellow sheeting indicate that the conspicuity of the signs is much higher, the increased conspicuity ultimately must prompt a change in motorist behavior for highway safety to be improved. Therefore, the purpose was this research was to evaluate the effectiveness of fluorescent yellow warning signs in improving highway safety at hazardous locations. A before and after study used surrogate measures to evaluate the safety effectiveness of replacing existing yellow warning signs (engineer or high intensity grade) with fluorescent yellow warning signs (diamond grade) at seven hazardous locations. The results of this effort indicate that fluorescent yellow warning signs increased the safety at four of the seven sites by providing a more conspicuous warning to motorists. However, since surrogate measures were used, the actual collision savings are unknown.

Pełny tekst źródłaBackground: Modified Early Warning Score, MEWS, is a scoring system (0-17 points) for assessment of patients’ vital signs. The function of MEWS is to detect deteriating patients at an early stage, and being able to put in adequate treatment before their physical condition worsens. The benefits from using MEWS on oncology patients have so far been researched to small extent. A study from 2012 indicates that MEWS is not an effective tool for detecting deteriation in oncology patients. Objective: To research if oncology patients have scores 0-17 on MEWS measurements the week before they are deceased. The writers also intend to research which certain parameters within MEWS caused higher overall scores, and lastly whether there are any differences in scores between men and women. Methods: A retrospective review of medical records was performed on a total of 104 MEWS measurements belonging to 70 deceased patients. Results: The main results show an average MEWS of 2,99 points during the last week of the patients’ lives. Respiratory rate was the variable within MEWS to cause elevated scores (≥1) most often. The average MEWS increased from 3,13 points the seventh day before death to 8 points the last day before death, but due to the low frequency of measurements from the last day of the patients’ lives, it is not possible to make any assumptions based on these results. Furthermore, the initial loss of patients meeting the inclusion criteria was substantial due to low prevalence of registered MEWS. Conclusion: The results indicate that MEWS is not used on oncology patients to a great extent. It is not, however, possible to determine whether MEWS is a relevant assessment tool in care of oncology patients, and further research is therefore needed.

Pełny tekst źródłaBackground: Early recognition of serious clinical deterioration is of great importance for minimizing suffering and serious adverse events. For early recognition, several physiological track and trigger systems have been developed, among them the early warning scores. These have been implemented in many places across the world but there is uncertainty about adherence to these systems. Aim: The aim of this study was to investigate adherence to Early warning score-systems and to evaluate what factors affect this adherence. Method: The study was conducted as a literature review including 14 articles with quantitative, qualitative and mixed-methods approaches. Searches were made in the PubMed, CINAHL and Web of Science databases. Content-analysis was used to identify themes. Results: Adherence seems higher to observations than to clinical responses. The main factors affecting adherence are the clinical experience of nurses, collaboration between professions, staffing, miscalculation, documentation and reporting. Conclusion: Adherence to EWS is lacking in many ways and several causes for this have been accounted for. Factors affecting adherence was the clinical experience of nurses, cooperation between professions, staffing, miscalculation, documentation and reporting.

Pełny tekst źródłaABSTRACT Background: Patients with surgical conditions are complex, since many patients have various medical diagnoses besides their surgical condition. Apart from complicating care and treatment, this makes it difficult to detect deterioration in the patient's condition. In order to assess the patient's condition, objective and easily measurable parameters are preferably used. A scoring system, the Modified Ear ly Waming Score, MEWS, was developed in the early 1990s and based on some ofthe patient's vital functions: respiratory rate, heart rate, systolic blood pressure, body temperature, alertness/awareness and urine output. The result varies between 0 and 17, with 0 demonstrating normal vital functions. Objective: To describe the distribution of MEWS scores for emergency patients with surgical condi tions in two surgical wards at a university hospital in Sweden, and to examine what actions had been taken based on the MEWS scores. Methods: A retrospective review was performed on MEWS measurements and medical records for 94 patients. Results: In total, 229 MEWS measurements had been performed, ofwhich 76 were taken on arrival at the ward, and the remaining 153 <luring the continued hospitalization. The number ofMEWS measurements per patient ranged from 1 to 31. Nineteen actions, based on MEWS scores, related the nursing professions were found, with the administration of painkillers and repeated checks ofthe pa tient's vital functions, being the two most common. Twenty-two medical procedures, based on MEWS scores, were identified, where sampling for bacterial cultures or prescribing extra intravenous fluid were the most frequent. No patient was transferred toa higher level of care because of their MEWS score. Conclusion: MEWS measurements were performed in 85% of the patients and the median result was 1 of maximum 17. Different actions, related the nursing or medical profession, were taken at a me dian result of 4. No patient was transferred toa higher level of care. The most common actions were administration of painkillers, repeated checks ofthe patient's vital functions, sampling for bacterial cultures and prescribing extra intravenous fluid

Pełny tekst źródłaSAMMANFATTNING Syftet med studien var att undersöka om bedömningsinstrumentet Pediatric Early Warning Score, PEWS, är till användning och vägledning på barnavdelning med avseende att upptäcka försämring av barns vitalparametrar. För detta användes en beskrivande kvantitativ design med kvalitativa inslag. Metod: Ett studiespecifikt enkätformulär gick ut till 86 personer (undersköterskor, sjuksköterskor och läkare på två pediatriska vårdavdelningar). Av dessa besvarades 36 enkäter. Resultat: Av 36 svarande ansåg 25 att man snabbare upptäckte försämring av vitalparametrarna hos barnet. Många ansåg att de fick snabbare gensvar från jourläkare genom att uppge en bedömningssiffra över barnets hälsotillstånd. Slutsats: Med hjälp av bedömningsinstrumentet PEWS upplevde personalen att en upptäckt av försämring av barnets vitalparametrar gjordes tidigare, samt att gensvar från jourläkare erhölls snabbare. Personalen upplevde en ökad trygghet i sitt arbete då man hade ett arbetsredskap till hjälp.

Pełny tekst źródłaA study on the graphic presentation of information content and comprehensibility of warning signs in packages of toys commercialized in the Ludovicense market considering the Cultural Ergonomics. This research was conducted in the city of São Luís-MA with the goal of identifying graphics and informational aspects of the verbal warnings signs and identify the degree of responsiveness of the pictorials warning signs. For this we divided the research into three phases. In phase 1, we analyzed a sample of 612 warning signs printed on toy packages represented in verbal and pictorial modes divided into seven (7) classification of toys, collected between June and August 2013. It is considered graphic and informational variables in the analytical study: model of the Graphic Variables Presentation proposed by Mijksenaar (1997); guidelines proposed by Wogalter et al. (2002); and INMETRO (2005) variables. In phase 2 and 3 we selected and tested 12 pictorials with potential buyers of toys. From the results obtained is possible to affirm that, in general, the warning signs, that are in verbally mode, are in accordance with the literature and standards recommended and that the degree of understandability of the pictorial warning signs are, in mostly, above the level recommended by ISO 9186. Nevertheless, it is noteworthy that in 10 of the 25 variables (graphics and informational levels) most of the warnings has shortcomings and, these, consequently, may cause damage / injury to the indirect consumer, the children.
Estudo sobre a apresentação gráfica, de conteúdo informacional e de compreensibilidade de sinais de advertência em embalagens de brinquedos comercializados no mercado ludovicense considerando a Ergonomia Cultural. Esta pesquisa foi desenvolvida na cidade de São Luís-MA com o objetivo de identificar os aspectos gráficos e informacionais dos sinais de advertências verbais e identificar o grau de compreensibilidade dos sinais de advertência pictóricos. Para tanto dividiu-se a pesquisa em três fases. Na fase 1, analisou-se uma amostra constituída por 612 sinais de advertência impressos em embalagens de brinquedos representados nos modos verbal e pictórico distribuídos em 7 (sete) classificações de brinquedos, coletados entre os meses de junho a agosto de 2013. Consideraram-se as variáveis gráficas e informacionais no estudo analítico: modelo das Variáveis da Apresentação Gráfica proposto por Mijksenaar (1997); as diretrizes propostas por Wogalter et al. (2002); e as variáveis Inmetro (2005). Na fase 2 e 3 selecionaram-se e testaram-se 12 advertências pictóricas com potenciais compradores de brinquedos. A partir dos resultados obtidos é possível afirmar que, de maneira geral, os sinais de advertência no modo verbal estão em conformidade com o que a literatura e a norma recomenda e que o grau de compreensibilidade dos sinais e advertência no modo pictórico estão, em sua maioria, acima do grau recomendado pela ISO 9186. Contudo, ressalta-se que em 10 das 25 variáveis analisadas (níveis gráficos e informacionais) a maioria das advertências apresentou deficiências e, estas, consequentemente, podem provocar em danos/prejuízos para o consumidor indireto, as crianças.

Along with the social progress, the warning label often most can transmit the important news, because its direct representative superior pass life and death security problem, therefore warning label it symbolized that the internal graph size, will affect the human regarding the indication significance identification strength. This research is for the purpose of discussing the warning label design regarding to receive trying regarding to recognize the insight and magnanimity and vision of achievements other intuition response influence, as well as visual related consciousness principle basic concept whether to have the relatedness, arrives at the mark effect by the visual consciousness, explains and the indication mark manifestation related vision viewpoint, and take will do with the indication character correlation''s constitution question as the future life indicates improvement and the revision the design and manufactures reference of the new indication. As to the visual psychological phenomenon, the list the situation creates consciousness transmission time from many special sentiments the identification detention, urges this kind of phenomenon the reason to be possible to divide into three points: (1) identical indication under the different color, has the different impression; (2) identical indication under the different shape, has the different impression; (3) identical indication under different laying aside position, also will have the different impression. An experiment minute two stage, of first stage adopts the questionnaire way, whether lets subjective reply oneself by chance the measuring basis identification of ability of warning label own state of health as well as some question influential experiment. The second stage main goal lies in the discussion to change measuring to 20 kind of revisions the warning label software of the program design to produce by Visual Basic by the stochastic demonstration the warning label to determine identification of strength subconscious whether to have the difference. This research was measured that the object by the school in the student primarily, was measured the population is 38, and will choose of warning label the improvement from now on four different type (CNS, ISO to have the caution inscription, the ISO non-caution inscription, CNS& ISO) carries on test of the reaction time as well as the intuition reply, the test result besides must understand that answers option of as well as according to He Zhong the measuring reply based on the judgment option also has presents the place, discovered by way of the statistical result, CNS has of warning signal the outer edge not to have of warning signal reaction time the outer edge also to be shorter than, ISO in has the caution inscription the clear clear graphical representation significance which must come compared to the non-caution inscription, but the total reaction time also has high Reliability. Therefore test of the warning label, based on the safety factor consideration, the warning label should design the simple easy to understand way to cause clarity of the it discernment warning label, therefore, of principle of design the warning label, is worth discussing thoroughly, the interesting graphic language will represent the specific thought that transmits gives the user, enables the user to break through the language culture cognition the barrier, carries on the non-barrier the idea to transmit and to have correct, the specific judgment and the motion, achieves the fast identification and the safe goal.

This study established the tourism security alarm sign system and discussed the relationship between the attentions and preferences toward the tourism security alarm signs of people, by the physiological mode (eye tracking) and psychological model (preferences and cognitive behaviors). It applied the law of comparative judgment to discuss the preferences of the tourism security alarm sign system and used an eye tracker to develop the attentions of the tourism security alarm signs. There are two stages in this study: it applied the law of comparative judgment (LCJ) to analysis the beauty, the conspicuousness and the appropriateness of preferred alarm signs of the stop and warning signs in the first stage. We arranged 12 different warning signs and stop signs in 66 groups and 28 groups by paired comparisons. Convenience sampling method was applied to select the surveyed students. We made them stare into the paired photos (in 15 seconds) and finish the survey to arrange the rank of preferences by the law of comparative judgment. The second stage, we selected 23 persons as the experiment subjects. We screened the suitable signs by the study of the first stage and recorded the eye tracking information of subjects by an eye tracker. We also performed a survey to figure out the visual behavior of signs by understanding their attention behaviors. We collected 359 valid samples in the first stage (the effective response rate was 82.1%). The result revealed interesting signs are the most beautiful, and the second one are the standing signs for participants. The participants also identified the conspicuous and simple-designing signs are more suitable in tourism attractions. According to above, we could know that most familiar style for participants is the traditional stop sign. We collected the following results from the second stage by eye tracking analysis: (1) In warning signs, the interesting and cute signs are preferred as the most beautiful and conspicuous signs, and the standing form is preferred as the most suitable form to communicate the messages; in stop signs, the simple-designing and bright color signs are the most conspicuous and most supported signs by general people. (2) Most people who have seen the signs are willing to obey the restrictions. And people also identify with that everyone should aware the potential risks in their tourisms. It should be a common sense. (3) Most people support that there is essential to set alarm signs. (4) People usually depend on the alarm signs in tourism attractions, and the signs could arouse people''s alertness. (5) Recreational behaviors effect some specific topics, especially in these five options: doing outdoor recreational behaviors or not, doing adventure activities or not, having a habit of tourism or not, notifying the warning or stop signs and the effect of sign''s integrity toward stop signs.

Pełny tekst źródłaObjective: To increase knowledge about risk-taking behaviours as risk factors and potential warning signs for suicide in adults. Engaging in risky behaviour is an identified warning sign for suicide in adolescents, however has not yet been well researched in adults. Method: An anonymous sample of 713 Internet users (77.1% female; 78.5% Caucasian aged from 18 to 71) completed a 20-30 minute anonymous online survey measuring five domains of risk perceptions and behaviours using The Domain-Specific Risk-Taking (Adult) Scale (DOSPERT; see Appendix B). The Suicide Behaviours Questionnaire – Revised (SBQ-R; see Appendix C) was used to group participants as suicide-risk or non-suicidal. 401 participants were identified as suicide-risk. Analyses investigated group differences in risk perceptions and behaviours in suicide-risk and non-suicidal participants. Risk behaviour differences were also examined for participants who scored highly on an SBQ-R item relating to future suicidal intent, in order to identify potential proximal warning signs. Results: Behavioural and/or perceptual differences were found between suicide-risk and non-suicidal participants across all risk five domains. Potential proximal warning signs included engaging in extra-marital affairs, driving a car without a seatbelt and walking home alone at night in an unsafe area. Conclusions: The implications of these findings are far-reaching in terms of their clinical utility; clinicians and gatekeepers can be alerted to a new range of risk factors and warning signs to indicate a distal or proximal suicide risk. Definite differences were found in risk behaviours between suicide-risk and non-suicidal adults, indicating that risk-taking is important risk factor for suicide beyond adolescence.

The topic is very important. Static identification is vulnerable to environmental factors while dynamic identification can reduce it but with a slow speed. This study proposes a system based on dynamic image processing. The system first detect whether there is a speed limitation sign. Once the sign has been detected, the system will lock the sign and take a series of images. Then, the system performs image processing to avoid noise interference. Then the system uses Google Maintained Tesseract-OCR Identification System to recognize. Each image will be count the repetition rate and the highest one will be selected. The recognition rate is about 85% in average under the condition that when the car speed is about 60~70 kilometers and a good weather. Though the recognition rate is not so high, however, for the assistance of the drivers, the system is feasible enough.

People are living longer because of advances in medical and health technology, and elderly population gradually increased. With the effects of low birth rate, the number of elderly living in long-term care institutions was gradually increased. However, the number of nurses in institutions is fixed, so how to use information technology to assist them to monitor the vital signs of the elderly is a worth discussing topic. Furthermore, it is lack to set the earninig warning range of the elderly’s vital signs that meet their personal situation, and there are few papers using the control charts in the research of the earninig warning range of the individual patients’ vital signs. Therefore, this study used the univariate and multivariate control chart techniques for long-term care patients to look for a variety of the warning range of their vital signs, and proposed the earning warning methods for the individual patient’s vital signs. This study proposed the whole and individual health interval for the four vital signs such as temperature, pulse, respiration and blood pressure in the univariate analysis. The whole interval is divided into normal human interval and the subjective long-term care elderly’s interval. And the individual interval is divided into personal interval and statistical process control (SPC) interval. The normal human intervals are referenced from the literatures. The subjective long-term care elderly’s intervals are set by adjusting the normal human intervals in accordance with the average of the experimental samples. The personal interval is set by looking for a suit one from the individual's averages plus or minus a few standard deviations. The last SPC interval is set by using SPC software to calculate the individual values and moving range to find the individual healthy interval. According to the four healthy intervals described above, this study sets three alarm interval colors of red (R), yellow (Y) and green (G) in accordance with the severity. In the multivariate analysis, this study used the Hotelling T2 control chart method to consider three vital signs such as body temperature, pulse and blood pressure at the same time. This study sets the multivariate early warning by using the upper limit identified from the Hotelling T2 control chart and the orange (O) warning light is truned on when the observed value exceeds the upper limit. In practical operation, this study suggests the automated sliding warning interval that uses the concept of the time window to calculate the next warning intervals. When the system is moinitoring the patients’ vital signs, it will fine-tune the warning intervals automaticly and dynamicly. So adjusting the personal health interval automaticly and dynamically can be better to meet the demand of setting the intervals according to the patient's condition, and it can also reduce the nurses’ workload. In the future, we can use the artificial neural networks or other data mining techniques to analyze the impact of age, gender and disease for vital signs to find out some groups, and then use our early warning method to find more suitable intervals of these different groups.

Prohibitive and warning signs are two major traffic signs used to introduce traffic information to drivers. Because prohibitive traffic signs provide prohibitive information by negatively presented concept and warning traffic signs provide warning information by symbol in the triangular frame, the effect of prohibitive and warning traffic signs design on users'' subjective preference and visual performance deserves to be discussed further. This study includes two experiments. A preference-rating test was held in stage I of experiment I to investigate the prohibitive traffic signs effects of sign-type (twelve types) and slash-type (a slash over the symbol, a slash under the symbol, a partial slash, and a translucent slash) on the subjects’ subjective preference. Analysis of results showed that subjects showed the worst preference on signs with translucent slash and partial slash. Additionally for sign 1, sign 2, sign 7, sign 8 and sign 9, subjects performed no significant different preference on signs with over slash and under slash. However for sign 3, sign 4, sign 11 and sign 12, subjects showed significantly better preference on signs with under slash than signs with over slash, and subjects showed no significantly different preference on signs with over slash, translucent slash, and partial slash for sign 5 and sign 10. A driving simulating experiment was developed in stage II of experiment I to evaluate the prohibitive traffic signs effects of sign-type, slash-type, age (a young group, a middle-aged group, and an elderly group), illuminance conditions (daylight and dusk) and driving velocity (40 and 60 km/hr) on the subjects’ visual performance. Analysis of results showed that sign type, slash type, illuminance conditions, and driving velocity were all significant factors for the subjects’ visual performance. Subjects performed better visual performance when the pictorials of traffic signs were simple, clear and when its slash did not cover the major pictorial features of signs. Subjects performed the best visual performance for signs with partial slash; then under slash and translucent slash, and performed the worst visual performance for signs with over slash. Generally, young and middle-aged groups performed significantly better visual performance than the elderly group. The visual performance of young and middle-aged groups was significantly better than the elderly group for sign 4, sign 5, sign 6, sign 9, sign 10, sign 11 and sign 12. However for sign 1, sign 2, sign 3, sign 7 and sign 8, young group performed the best visual performance; then middle-aged group, and the elderly group performed the worst visual performance. Regarding the illuminance condition of driving, subjects performed better visual performance in daylight. The preference-rating test was also held in stage I of experiment II to investigate the warning traffic signs effects of sign-type (twelve types) and the symbol size (10%, 15%, 20%, and 25% of the sign area) on the subjects’ subjective preference. Analysis of results showed that the symbol size was a significant factor for the subjects’ preference. The 20% symbol size was the most significantly preferred signs; then 25% and 15%, and the 10 % symbol size was the worst preferred signs design. The driving simulating experiment was also held in stage II of experiment II to evaluate the warning traffic signs effects of sign-type, the symbol size, age (a young group, a middle-aged group, and an elderly group), illuminance conditions (daylight and dusk) and driving velocity (40 and 60 km/hr) on the subjects’ visual performance. Analysis of results showed that sign type, the symbol size, illuminance conditions, and driving velocity were all significant factors for the subjects’ visual performance. Subjects performed better visual performance when the symbols of traffic signs were simple, clear and with appropriate interval between the symbol and the triangular frame. Generally, young and middle-aged groups performed better visual performance than the elderly group. Additionally, young and middle-age groups performed the best visual performance on signs with 20% and 25% symbol sizes; then 15% symbol size, and performed the most visual performance on signs with 10% symbol size. However, elderly group showed the best visual performance on signs with 20% symbol size; then 25% and 15% symbol sizes; and performed the worst visual performance on signs with 10% symbol size. Regarding the illuminance condition of driving, subjects performed better visual performance in daylight.

Recently there has been much attention paid to financial crises of a company. Therefore, we look at the relationship between the financial situation of the company before the crisis and the probability of a financial crisis occurring. The financial situation included financial positioning, profit and cash flow prior to the financial crisis. This paper continues the research of Tsai(2016), it uses visualization software to analyze financial information from a company’s financial statements. The usability of the data mining analysis was put into chart form. Furthermore, verifies the results feasibility of using financial indicators to notify the company of potential problems. The results of data mining and financial indicators were used to generate the data and use cases used in this paper. Tableau was used to visualize the financial warning indicators chart, which will be given to experts to determine the applicability of the chart and the feasibility of using the defined financial indicators. The same chart serves as the feedback mechanism for the results gathered from data mining. Utilizing a questionnaire and the chart to determine whether the usability of the financial indicators and the results from data mining and also the feedback mechanism. Using the results of the questionnaire we can verify the thresholds of the domain-driven data mining decision tree. We can check if it is applicable to the electronics and traditional industry. The visualization chart can be used to support the data analysis and the feasibility of the feedback mechanism. The study concludes that only using a single financial indicator cannot fully warn companies of potential financial crisis. Using a combination of financial indicators on a dashboard, the visual analytics chart can be used to compare the financial indicators to determine if a company might have a financial crisis. The design of the warning threshold and the explanation of the financial indicators can affect the user’s configuration of the dashboard which may affect the results of the feedback mechanism.

Suicide is an important public health issue in Taiwan. In 2016, suicide death rate in the males is about 2.1 times that of the females (Ministry of Health and Welfare, 2016). Compared to other occupations, Army consists of mainly males and it is characterized by hierarchy, obedience, and mobilization of duties which all make soldiers a high-pressure population. Therefore, the soldier's suicide issues and prevention strategies need to be concerned more seriously.Previous literature revealed that most suicide victims scarcely seek professional help for their suicidal ideation before action. However, in one week to ten days before the attempts of self-injury, more than half of all suicidal individuals conveyed significantly relevant verbal, nonverbal or behavioral messages to nearby persons. If these aforementioned clues can be recognized, the potential suicide victims can be identified for intervention.To reduce suicide risk, regardless of rank level in military personnel, everyone is anticipated to have the ability to detect suicide warning signs and help potential suicide victims. The purpose of this study was to investigate the effects of a suicide-awareness program to enhance military personnel’s awareness of suicide warning signs. The study is a randomized control trial. In the interest of convenience, the researcher sampled a total of 144 military personnel from two army battalions in Eastern Taiwan. The study period lasted from May to June 2017. After singed inform consent provided, the participants were randomly assigned to an experimental group or control group.All participants were asked to complete questionnaires (including the “Awareness of Suicide Warning signs Questionnaire” and the “Demographic Data” Questionnaire) before taking the education session. These questionnaires provided demographic data and information about military personnel’s pre-training awareness of suicide warning signs and their responses while encountering a potentially suicidal individual. After filling in the questionnaires, all participants underwent the educational intervention. Both groups attended the 30-min regular mental health education. At the end of the regular mental health course, the control group was asked to complete the same questionnaires again. The experimental group continued to receive the 90-min suicide-awareness program and complete the same questionnaires again afterwards. Data were collected in May to June 2017, providing a total of 139 valid questionnaires. We used the SPSS for Windows (version 22.0) statistical software to analyze the data. The result showed that: 1. At the pretest, 139 participants were only aware of 15 items (47%) of the 32 items of suicidal warning signs, and only 33% of 139 participants presented that they would suggest seeking professional help if encountering a potentially suicidal individual.2. The results of the pre-test showed that the mean scores on awareness of suicide warning signs were not affected by demographic variables. However, those participants who believed there will be signs before committing suicide did exhibit a better awareness.3.After the intervention, the mean scores of experimental group on awareness of suicide warning signs increased from 4.04 to 4.44,( p<0.05).The experimental group was aware of 29 items (91%) of the 32 items of suicidal warning signs. Moreover, the number of those who would suggest their colleague seek professional help in the experimental group increased from 26 at pre-training to 46 at post-training (p<0.05).In contrast, statistical analyses showed that the difference in control group on the mean scores of awareness of suicide warning signs and their responses if encountering a potentially suicidal individual were not statistically significant. It shows that the placement of the suicide awareness program can enhance the military personnel’s ability to be aware of suicide warning signs and then further strengthen their willingness in referral. Therefore, in order to facilitate the effectiveness of suicide prevention in the military, it is recommended to incorporate the 90-minute suicide awareness program implemented in this study into the routine mental health education program.

In today’s turbulent financial markets, fraud and corporate scandals have become increasing common. New technologies have made it much more difficult for individual investors to detect and safeguard themselves from these increasingly complex scams. Over the past ten years corporate governance principles have been tested, and the weaknesses found in ethical values have made it even more important to be exceedingly aware of the inner workings of corporations. Much research has been done analyzing these companies and their leadership to find the reasons behind the perpetrated fraud. With the help of archival data we can find ways to alert the individual investor, making him more aware of the possibility that accounting figures that seem ‘too good to be true’ – may actually be false. In this paper we examine the internal and external causes of fraud in order to discover methods of early detection and prevention.

Accidents are a leading cause of death to preschool children in Taiwan. There are thousands of children unfortunately killed or injured because of fire every year worldwide (Peden et al., 2008). According to the statistics, about two events monthly that children play with fire because of neglect and lack of safety education in Taiwan. Accidents are a constant threat to the lives of children, because preschool children are accident prone, this study targets on preschool children ages form 4 to 6 and their recognition of warning signs. This study consists of two surveys. The expressions of warning signs survey attempted to explore how preschool children use drawings to express the image of “do not play with fire”. The cognitions of warning signs survey used a questionnaire to determine children’s understanding of warning signs; and interview method was conducted with the subjects to verify the extent of their comprehension. In the expressions of warning signs, the results Among the expressions of “do not play with fire,” a “scene of fire” was mostly drew by the 4 and 6-year-old children, who mainly portrayed scenarios depicting the harms caused by playing with fire; “do not play with fire” was used by the 5-year-old children, who mainly used images to express the concept. In terms of the visual representation of “do not play with fire,” the 6-year-old children tended to use symbol representation, mainly the cross; the 5-year-old children tended to use action representation, mainly the palm. In the cognitions of warning signs, the results reveal that preschool children’s understanding of warning pictograms is tightly linked with their life experience and age. Most of the preschool children were able to recognize palm and triangle frame images, and “red” color as indicating warning. The differences among 4 and 5-year-olds children recognized “palm” the most as a prohibit sign, whereas 6-year-olds children recognized “cross” the most. Using simple and concrete images are able to inform children of possible injury, which effectively achieves the educational goals of these images. Therefore, based on the results of these investigations, which suggests that while designing and educating of children warning signs in the future, it should take the results of this study as reference.

The method of survey was adopted in this study, focusing on 1010 students with 3rd, 4th, 5th, and 6th grades in elementary school in four South cities/counties as the object. It was aimed at the discussion of objects’ recognition of campus’s public safety, the awareness percentage of existing safety warning signs and the level of confusion on these signs, so that as the basis of the evaluation on the place to be set up “safety sign board” and that of the improvement of safety warning signs. This study was conducted in three steps. Firstly, the methods of Likert-type scales and Match were adopted to investigate the danger factor across the campus, to evaluate the awareness percentage on safety warning signs, and to analyze the confusion matrix. In the second step, by referring to the existing books of the icon design, the principles of a set of icon design was categorized and integrated. Then, the awareness percentage which were less than 67% standard value from ISO suggested and high confusion signs were re-designed, and I used the Preference method to evaluate the preference of signs. Finally, the Match method was adopted again for evaluating the awareness percentage and analyzing confusion matrix. The result showed: 1. The activity space on campus which is dangerous for children can be divided into five levels. They are laboratories, classrooms and corridors, kitchen and the associated facilities, each entrance on campus, and sport equipment area, while the danger factors which cause accidents more easily are stumble by protruding objects, slip, hit head by short buildings, hit body by falling objects, and converging attack hands. 2. In the first step with 15 safety warning signs, there are ten signs which awareness percentage are beyond 67% standard value ISO suggested, and there are five ones without reaching the standard value. In addition, even some signs are beyond 67% standard value, but in the meantime there is the occurrence of confusion. 3. The signs which have been re-designed and evaluated by Preference method were beyond 67% standard value ISO suggested in the evaluation of second time match method. Compare to the first time one, the overall awareness percentage (89.8%) were obviously different (p<.001).Upon the results stated above, I suggest that, in the future, when each elementary school plan on designing safety warning signs, the meaning, recognition, and the design of the signs should be suitable for the elementary school students’ personal factor. I hope, when joining the activities on campus, the students can learn more about the information the signs attempt to deliver. Thus when recognition and activity combines together, safety will come afterward.

This research differs from the previous ones in several ways. I use 15 financial variables and 8 non-financial variables to build up financial crisis forecasting model. Through two-phase models, I use Logit model to analyze their forecasting capabilities of these financial and non-financial variables first, and then use the D-Score model to evaluate the D scores of the delisting companies. Research sample period covers form 2004 to 2009, and I apply to 52 delisting companies. Comparing the D-score of the delisting companies with those of the normal companies, the D-Score model is used to demonstrate factors that can be used to predict the probabilities of delisting in the coming years. The results of this study show that the financial factors such as Debt ratio, Quick ratio, Operating Profit ratio, EPS, Operating Free Cash Flows; and the non-financial factors such as Director Ownership ratio, Director Pledge ratio, Change of Managing Director, President and Accounting Supervisors, have explanatory power for the delisting events. Using the D-Score model, the average score of the delisting companies is 6.94, which is higher than that of the normal companies, indicating that these financial and non-financial variables can be used to forecast which companies will go bankruptcy in the future. Applying this model to 2007-2009 delisting companies, the D-Score is 6.58, (which is well above the benchmark the models predict). Thus I believe that the Logit and the D-Score model are effective for forecasting whether companies will delist or not.

Pełny tekst źródłaIn dieser Studie wurde die intraoperativ durchgeführte Hirnstammaudiometrie (BAEP) sowie die intraoperative direkte Ableitung der cochleären Nervenfunktion bei 162 Patienten analysiert, um die kritischen Zeichen für einen postoperativen Hörverlust nach transtemporaler Akustikusneurinomoperation zu identifizieren. Eine logistische Regressionsanalyse wurde durchgeführt, um herauszufinden, wie viel diese Zeichen zur Prädiktion eines postoperativen Hörverlustes beitragen. Die signifikanten Warnzeichen für einen postoperativen Hörverlust können vom kritischsten zum am wenigsten kritischen wie folgt angeordnet werden: 1. permanenter intraoperativer Verlust der Welle V, 2. permanenter intraoperativer Verlust der Welle V in Kombination mit einer dreischrittigen Erhöhung der Stimulusintensität und 3. dreischrittige Erhöhung der Stimulusintensität, um eine klare Reaktion zu erhalten. Die Sensitivität und Spezifität jedes oben genannten signifikanten intraoperativen BAEP-Zeichens wurde berechnet. Der permanente intraoperative Verlust der Welle V war das spezifischste Zeichen. Diedreischrittige Erhöhung der Stimulusintensität, um eine klare Reaktion zu erhalten hatte die höchste Sensitivität. Die dreischrittige Anhebung der Stimulusintensität, um klare Reaktionen zu erhalten, stellt somit ein effektives Warnzeichen für eine mögliche intraoperative Schädigung des Nervus cochlearis dar. Dies kann genutzt werden, um den Chirurgen frühzeitig, d.h. vor dem Auftreten eines permanenten intraoperativen Verlustes der Welle V, zu alarmieren. In Bezug auf die direkte Ableitung der cochleären Nervenfunktion wurde es fest gestellt , dass je höher die intraoperativen Schwellen der direkten Ableitung der cochleären Nervenfunktion sind, desto höher ist die Häufigkeit des postoperativen Hörverlusts. Die intraoperative direkte Ableitung der cochleären Nervenfunktion hat eine Sensitivität von 77,42% und eine Spezifität von 55,56% bei einem optimalen Grenzwert > 57,5 dBnHL. Schlussfolgend lässt sich sagen, dass die intraoperativen BAEPs und die direkte Ableitung der cochleären Nervenfunktion eine wichtige Rolle bei derVorhersage des postoperativen Hörverlusts bei Patientenwährend der Resektion eines Akustikusneurinoms spielen

It is often ignored to recognize early signs of sudden cardiac arrest and risk factors of clinical deterioration, when rapid assessment and resuscitation of critical conditions in in-hospital or out-of-hospital may need to be carried out. The study aim was to investigate the relationship and outcomes of cardiac arrest, early warning signs and cardiopulmonary resuscitation in hospital inpatients. The is a retrospective chart review study by reviewing clinical data of patients who experienced sudden cardiac arrest and cardiopulmonary resuscitation. The patients’ medical records in hospital data bank dated from January 2013 to December 2014 were collected from a large mental hospital in southern Taiwan. The data were analyzed by applying SAS 9.4 full version. A total of 310 patients met entry criteria. Results showed that demographic variables such as age and sex were not significantly correlated with success in first aid management. Internal Medicine had more cases of cardiac arrest, although it did not reach statistically significant difference. The past history of diseases such as heart failure, respiratory failure and cancers was shown to be non- statistically significant correlated for first aid management. Initial respiration changes when emergency occurs and success in first aid management were statistically significant correlated. Early warning signs such as temperature, heart rates, pulse rates, systolic pressure, diastolic pressure, blood oxygen saturation and pain scores showed significant differences over time. A number of results were found: (1). patients had significant changes in respiratory rates (P =0.01), blood oxygen saturation (P =0.01) and pain scores (P =0.002) within first monitored one hour of the warning signs. (2). Significant changes in temperature (P=0.008), respiratory rates (P =0.001), pulse rates (P =0.03) and blood oxygen saturation (P =0.01) in the monitored second hour of the warning signs. (3). Significant changes in blood oxygen saturation (P =0.03) in the monitored third hour of the warning signs. (4). Significant changes in respiratory rates (P =0.03) in the monitored fourth hour of the warning signs. (5). Changes of heart rates (P =0.036), respiratory rates (P =0.013), pulse rates (P =0.029), and systolic pressure (P=0.005) were all reached statistical significance in the monitored fifth hour of the warning signs. A total of 266 inpatients showed first monitored rhythm as ventricular flutter (VF) and pulseless ventricular tachycardia (VT). Twenty-six patients (9.8%) received prompt defibrillation. Three inpatients’ defibrillation (1.1%) after the appearance of VT/VF is within three minutes. A rate of survival from cardiac arrest was associated with VT and VF to 31 inpatients (11.7%) There are a total of 39 inpatients (14.5%) who signed do not resuscitate (DNR) or removed life support system in 269 pulseless and no heartbeat deaths after first aid management. Reasons of cessation of CPR include patients with a hopeless prognosis (N=89, 28.7%), death (N=50, 16.1%), family signed DNR after first aid management (N=39, 12.6%), requests from family to end CPR (N=17, 5.5%), and return of spontaneous circulation after first aid management (N=149, 41.6%). The study also found that early warning signs and prompt defibrillation is beneficial to rate of survival. Hopefully, this study could help to improve the assessments of in-hospital cardiac arrest and early warning signs in order to decrease the incidences of cardiac arrest of inpatients, increase the success of cardiopulmonary resuscitation and inpatients’ survival rates, and decrease the physiological and psychological impacts and admission days.

"Computer-aided National Early Warning Score to predict the risk of sepsis following emergency medical admission to hospital: a model development and external validation study". 2019. http://hdl.handle.net/10454/17028.
Pełny tekst źródłaBackground: In English hospitals, the patient’s vital signs are monitored and summarised into a National Early Warning Score (NEWS). NEWS is more accurate than the quick sepsis related organ failure assessment (qSOFA) score at identifying patients with sepsis. We investigate the extent to which the accuracy of the NEWS is enhanced by developing computer-aided NEWS (cNEWS) models. We compared three cNEWS models (M0=NEWS alone; M1=M0 + age + sex; M2=M1 + subcomponents of NEWS + diastolic blood pressure) to predict the risk of sepsis. Methods: All adult emergency medical admissions discharged over 24-months from two acute hospitals (YH–York Hospital for model development; NH–Northern Lincolnshire and Goole Hospital for external model validation). We used a validated Canadian method for defining sepsis from administrative hospital data. Findings: The prevalence of sepsis was lower in YH (4.5%=1596/35807) than NH (8.5%=2983/35161). The c-statistic increased across models (YH: M0: 0.705, M1:0.763, M2:0.777; NH:M0: 0.708, M1:0.777, M2:0.791). At NEWS 5+, sensitivity increased (YH: 47.24% vs 50.56% vs 52.69%; NH: 37.91% vs 43.35% vs 48.07%)., the positive likelihood ratio increased (YH: 2.77 vs 2.99 vs 3.06; NH: 3.18 vs 3.32 vs 3.45) and the positive predictive value increased (YH: 11.44% vs 12.24% vs 12.49%; NH: 22.75% vs 23.55% vs 24.21%). Interpretation: From the three cNEWS models, Model M2 is the most accurate. Since it places no additional data collection burden on clinicians and can be automated, it may now be carefully introduced and evaluated in hospitals with sufficient informatics infrastructure.
