Abstract:
The International Association for the Study of Pain, IASP, has long proven that pain and its effects on the child can lead to pathological reactions that lead to behavioral changes in the form of functional and vegetative disorders, emotional responses such as loss of skills, sleep disturbance, or child's irritability, enuresis and others.There are currently a number of pain assessment scales for children of all ages that include many different parameters (cardiovascular and respiratory systems, changes in behavior, autonomic reactions in the form of changes in the function of the eyes, skin color, etc.) using a quantitative estimate to evaluate those signs.In the practice of a pediatrician and a family doctor, it is important to choose from a range of pain scales that are simple and accessible to all healthcare providers and other caregivers.We compared scales that are used most often and are recommended by the medical community. As well as investigating their use in practice, FLACC conducted a study of children with organic lesions of the central nervous system that had episodes of acute pain. Because this scale, in combination with the definition of autonomous regulation parameters, allows you to objectively assess the degree of pain experienced by the patient.KeyWords: рain, pain assessment, pain relief, pain scales, paliative medicine, pediatrics. Особливості застосування шкали оцінки болю в педіатріїГончар М. О., Уриваєва М. К., Кузнецова Д. О., Ткачук Л. М.Міжнародна асоціація з вивчення болю IASP давно довела, що біль та його вплив на дитину можуть призводити до появи патологічних реакцій, які ведуть до змін поведінки у вигляді появи функціональних та вегетативних розладів, емоційних відповідей, таких як втрата навичок, що сформовані, порушення сну або дратівливість дитини, енурез та інші. Доведено, що нездатність до локалізації болю у дітей раннього віку у клініці може мати системну відповідь у вигляді порушення компенсаторних систем, що швидко виснажуються.Наразі існує ціла низка шкал оцінки болю у дітей різного віку, які включають багато різноманітних параметрів (функціонування серцево-судинної та дихальної систем, зміна поведінки дитини, вегетативні реакції у вигляді змін функції очей, кольору шкіри тощо), використовуючи кількісний підрахунок для оцінки тих чи інших ознак.В практиці лікаря-педіатра та сімейного лікаря важливим є вибір з ряду шкал оцінки болю саме тих, що будуть простими й доступними для всіх медичних працівників та інших осіб, що доглядають за дитиною.Ми порівняли шкали, які використовуються найчастіше та рекомендуються медичним суспільством. А також дослідили їх застосування на практиці, за допомогою шкали FLACC провели дослідження дітей з органічними ураженнями центральної нервової системи, що мали епізоди гострого болю. Бо саме ця шкала в поєднанні з визначенням параметрів автономної регуляції, дає змогу найбільш об’єктивно оцінити ступень болю, що відчуває пацієнт.Резюме.

Abstract:
RÉSUMÉCette étude pilote a examiné les changements dans l’activité physique et la fonction chez les personnes âgées se déplaçant de logements communautaires aux maisons de retraite. L’activité physique a été évaluée en utilisant un Actigraph (GT3X +) moniteur d’activité; l’activité physique par type a été rapportée avec le questionnaire CHAMPS de l’activité. La fonction physique a été évaluée en utilisant le Test de Fitness Senior. L’activité physique totale, objectivement contrôlée, a diminué après la transition (p = 0,02). Rapports d’activité physique par type ont indiqué que seules les activités de la vie quotidienne ont diminué (p <0,01), bien que l’exercice intentionnel s’est augmenté (p <0,03) avec la transition. L’endurance et la force sont également améliorés (p <0,05 et p <0,04). Résultats du projet pilote indiquent que des avantages physiques possibles profitent de la vie de la retraite, bien que les efforts visant à réduire le temps sédentaire sont nécessaires.

Abstract:
RÉSUMÉLe but de l’Étude longitudinale canadienne sur le vieillissement (ÉLCV) est de recruter 50 000 participants âgés de 45 à 85 ans et de les suivre pendant 20 ans. Les processus d’échantillonnage et de recrutement pour une étude de cette envergure représentent d’importants défis. Statistique Canada a été approché pour collaborer avec l’ÉLCV dans le but de déterminer si l’Enquête sur la santé dans les collectivités canadiennes (ESCC) pourrait être utilisée comme véhicule de recrutement pour l’ÉLCV. Dans cette étude pilote réalisée en 2004, il a été déterminé que 63,8 pour cent et 75,8 pour cent des répondants accepteraient de partager leurs coordonnées et leurs réponses à l’ESCC avec l’ÉLCV, respectivement. Les réticences les plus souvent rapportées étaient reliées à la confidentialité, le manque d’intérêt et le niveau d’engagement demandé. Cette étude pilote a permis d’identifier quelques défis reliés à l’utilisation de l’ESCC comme véhicule de recrutement pour l’ÉLCV.

Abstract:
Objectif : La fatigue et les troubles cognitifs qui se manifestent après un cancer sont des effets indésirables qui, souvent, perdurent après les traitements et nuisent à la qualité de vie. L’étude vise à évaluer la faisabilité du neurofeedback et ses effets sur le fonctionnement cognitif et la fatigue des survivants du cancer, particulièrement la faisabilité des stratégies de recrutement, du protocole de recherche et des mesures de résultats. Devis : L’étude pilote de faisabilité est construite selon un devis avec groupe témoin mis sur liste d’attente pendant une période de 10 semaines. Les participantes servaient elles-mêmes de groupe témoin. Elles ont suivi deux séances de neurofeedback par semaine, pendant 10 semaines. Participants : L’échantillon était composé de survivantes du cancer du sein vivant à Kingston, en Ontario (n=16). Méthodologie : Les résultats ont été évalués à l’aide d’échelles d’autoévaluation validées, ainsi que par des tests neurobiologiques avant, pendant et après le traitement par neurofeedback. Résultats : La faisabilité du protocole de neurofeedback a été confirmée : la procédure s’accompagne d’une diminution significative des troubles cognitifs, de la fatigue, des troubles du sommeil et des symptômes psychologiques. Implications pour les services psychosociaux : Le neurofeedback pourrait se poser en thérapie complémentaire efficace et non invasive pour traiter les troubles cognitifs qui surviennent chez les survivantes du cancer du sein après les traitements.

Abstract:
RÉSUMÉLes procédures diagnostiques cliniques standards sont souvent inappropriées et fréquemment non applicables dans des études basées sur la population; pourtant, vérifier le statut précis d’une maladie est essentiel. Nous avons fait une revue systématique pour identifier des algorithmes, des critères, et des outils utilisés pour identifier 17 maladies chroniques, et avons fait la praticabilité de développer des algorithmes pour l’ÉLCV. Des 29 616 citations examinées, 668 papiers ont rencontré tous les critères d’inclusion. Nous avons déterminé que l’information incluse dans un algorithme de maladie différera selon le type de condition. Le diagnostic de quelques conditions symptomatiques, telles l’arthrose et l’arthrite, exigera la justification par des critères cliniques (par exemple, rayons X, mesure de densité osseuse) tandis que d’autres conditions, telles la dépression, se baseront seulement sur les dires des individus. Les conditions asymptomatiques, telles l’hypertension, sont plus difficiles à vérifier par les dires des individus et exigeront des mesures physiologiques additionnelles (par exemple, tension artérielle) et des mesures de laboratoire (par exemple, glucose). Cette étude pilote a identifié les outils nécessaires pour développer des algorithmes d’évaluation de diagnostic.

"Combining Crop Modeling with Remote Sensing Data Using a Particle Filtering Technique to Produce Real-Time Forecasts of Winter Wheat Yields under Uncertain Boundary Conditions." Remote Sensing 14, no. 6 (March 11, 2022): 1360. http://dx.doi.org/10.3390/rs14061360.
Abstract:
Within-season crop yield forecasting at national and regional levels is crucial to ensure food security. Yet, forecasting is a challenge because of incomplete knowledge about the heterogeneity of factors determining crop growth, above all management and cultivars. This motivates us to propose a method for early forecasting of winter wheat yields in low-information systems regarding crop management and cultivars, and uncertain weather condition. The study was performed in two contrasting regions in southwest Germany, Kraichgau and Swabian Jura. We used in-season green leaf area index (LAI) as a proxy for end-of-season grain yield. We applied PILOTE, a simple and computationally inexpensive semi-empirical radiative transfer model to produce yield forecasts and assimilated LAI data measured in-situ and sensed by satellites (Landsat and Sentinel-2). To assimilate the LAI data into the PILOTE model, we used the particle filtering method. Both weather and sowing data were treated as random variables, acknowledging principal sources of uncertainties to yield forecasting. As such, we used the stochastic weather generator MarkSim® GCM to produce an ensemble of uncertain meteorological boundary conditions until the end of the season. Sowing dates were assumed normally distributed. To evaluate the performance of the data assimilation scheme, we set up the PILOTE model without data assimilation, treating weather data and sowing dates as random variables (baseline Monte Carlo simulation). Data assimilation increased the accuracy and precision of LAI simulation. Increasing the number of assimilation times decreased the mean absolute error (MAE) of LAI prediction from satellite data by ~1 to 0.2 m2/m2. Yield prediction was improved by data assimilation as compared to the baseline Monte Carlo simulation in both regions. Yield prediction by assimilating satellite-derived LAI showed similar statistics as assimilating the LAI data measured in-situ. The error in yield prediction by assimilating satellite-derived LAI was 7% in Kraichgau and 4% in Swabian Jura, whereas the yield prediction error by Monte Carlo simulation was 10 percent in both regions. Overall, we conclude that assimilating even noisy LAI data before anthesis substantially improves forecasting of winter wheat grain yield by reducing prediction errors caused by uncertainties in weather data, incomplete knowledge about management, and model calibration uncertainty.

Ducarroz, Simon. "Le tabagisme et le risque de cancers liés au tabac chez les migrants en Europe." Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE1029/document.
Abstract:
Les migrations internationales augmentent et l'Europe ne fait pas exception avec plus de 10% de la population de l'Union Européenne en 2014. Une question importante est le tabagisme des immigrés qui pourrait entraîner des risques de maladies liées au tabac différents de ceux des natifs des pays hôtes. Pourtant, on ne connait que très peu l'usage du tabac, qui est une cause évitable de cancer, et les maladies liées au tabac chez les immigrés en Europe. L'objectif général de cette thèse était d'étudier l'usage du tabac et le risque de cancers liés au tabac chez les immigrés. Les objectifs spécifiques étaient de : enquêter sur le tabagisme et ses déterminants chez les immigrés en France (étude pilote TOBAMIG), comparer l'incidence des cancers liés au tabac entre les immigrés et les natifs au Danemark, mettre ces résultats en contexte avec les connaissances actuelles, et suggérer un design d'étude sur le tabagisme et le risque de cancer lié chez les immigrés en France. L'étude pilote TOBAMIG a collecté des informations sur l'usage du tabac dans un échantillon d'immigrés, représentatif pour la plupart des caractéristiques démographiques. Avec des modifications, les résultats indiquent la faisabilité d'une étude à grande échelle en France. Au Danemark, le taux d'incidence des cancers liés au tabac chez les immigrés était inférieur à celui des natifs ; cependant, de grandes disparités ont été observées par site cancéreux et pays d'origine, suggérant en outre un rôle du tabagisme dans les pays d'origine des immigrés. Enfin, deux designs d'étude sont proposés, qui varient en fonction de la quantité d'information recherchée, afin de mieux comprendre le tabagisme des immigrésInternational migration is increasing and Europe is no exception with immigrants accounting for more than 10% of the total European Union population in 2014. One pressing issue is tobacco use in immigrants as they may use tobacco differently from the natives of the hostcountry and this could result in differing tobacco‐related cancers (TRC) risks compared to those in the natives. However very little is known about tobacco use, a major avoidable cancer cause, and TRC in immigrants in Europe. The overall objective of this thesis was to investigate tobacco use and risk of TRC in immigrants. The aims were to: explore tobacco use and its determinants in immigrants in France (TOBAMIG pilot study), compare the burden of TRC between immigrants and natives in Denmark, put these results into context with current knowledge, and give guidance on how to set up a study on tobacco use and cancer risk in immigrants in France using the experience from the TOBAMIG pilot study. In the TOBAMIG pilot study information on tobacco use and its determinants was collected from a mixed sample of immigrants, suggesting a large‐scale study was in principle feasible, but modifications from the TOBAMiG approach were to be made. In Denmark, the overall TRC rate in immigrants was lower than that of the natives; however, large differences were observed by cancer‐site and by country of origin, suggesting that among other factors the smoking patterns from the immigrant’s country of origin have a primary role in the burden of TRC. Finally, with regard to a large‐scale study in France, two study designs are proposed, depending on the quantity of information sought, to better understand tobacco use in immigrants and risk of TRC

Abstract:
On assiste à un phénomène de transition épidémiologique dans les zones tropicales avec l’émergence des affections cardiovasculaires induites par l’athérosclérose. L'objectif de cette thèse était de contribuer à une meilleure connaissance de l’épidémiologie des facteurs de risque cardiovasculaire en population tropicale, en particulier au Bénin. Une analyse des prévalences des facteurs de risque cardiovasculaire en population générale au Bénin a été menée à partir de la base de données de l’enquête nationale STEPS. Une revue systématique des cohortes cardiovasculaires conduites en population générale en Afrique subsaharienne (ASS) a été réalisée. La méthodologie de la cohorte TAHES (Tanvè health study) a été élaborée ; une étude pilote a été mise en place. Les travaux montrent des fréquences relativement élevées de plusieurs facteurs de risque cardiovasculaire au Bénin et des différences suivant les milieux de résidence. Par ailleurs, ils soulignent la rareté des études de cohortes sur les maladies cardiovasculaires en ASS. Les résultats préliminaires de la cohorte TAHES pilote confortent l’idée de la faisabilité d’une étude plus largeAn epidemiological transition is observed in tropical areas with the growing of cardiovascular atherosclerosis diseases. The objective of this thesis was to contribute to a better knowledge of the epidemiology of cardiovascular risk factors in tropical area, particularly in Benin. An analysis of prevalence of cardiovascular risk factors in general population was led from Benin national STEPS survey. A systematic review of cardiovascular prospective cohort studies in sub-Saharan Africa (SSA) was conducted. Methodology of TAHES (Tanvè health study) cohort was described; a pilot study was implemented. These data show high frequencies of several cardiovascular risk factors in Benin; differences between urban and rural areas were observed. They underline the rarity of cardiovascular cohort studies in ASS. Besides, they support the hypothesis of cardiovascular cohort feasibility in general population in Benin

Farfal, Hervé. "Promotion de l’activité physique chez l’adolescent : interventions chez des jeunes obèses et des jeunes issus de familles socio économiquement défavorisées." Thesis, Pau, 2017. http://www.theses.fr/2017PAUU3028/document.
Abstract:
Cette thèse est basée sur le constat du manque d’activité physique (AP) chez les adolescents : environ 80% de cette tranche d’âge n’atteint pas les 60min quotidiennes recommandées. Cette situation aux conséquences sanitaires importantes, impacte davantage les jeunes les plus vulnérables comme les adolescents obèses et ceux issus de familles de position sociale et économique défavorisée. Deux études visant à promouvoir l’AP auprès de ces publics ont été menées : des mesures objectives de l’AP avant, pendant et après des interventions ont été réalisées dans deux contextes de prise en charge différents. L’objectif de la première étude était de tester la faisabilité et l’impact d’un programme d’AP à destination d’adolescents issus de milieux défavorisés en impliquant également un de leur parent. 18 parents et 22 adolescents ont participé au programme 1 parent – 1 ado. Il comportait deux fois deux heures d’AP par semaine pendant onze semaines pour chacun des groupes participants. Les niveaux d’AP ainsi que plusieurs paramètres anthropométriques, physiologiques et psychologiques ont été recueillis. Tous les participants ont suivi les onze semaines d’intervention. Les analyses ont montré que le seuil de 60 min d’AP quotidienne était atteint, uniquement pendant la durée du programme pour les adolescents. Celui de 30 min pour les parents l’était à tous les temps de mesures. Des analyses complémentaires ont révélé 1) des effets de la prise en charge sur l’AP modulés par l'âge chez les adolescents et par l'assiduité chez les parents, 2) une diminution de l’amotivation pour les adolescents les plus assidus et 3) une augmentation du bien-être pour les adolescents. Les résultats de cette étude pilote ont mis en évidence la faisabilité et l'efficacité d'un tel programme qui pourrait maintenant être déployé sous la forme d'un essai randomisé incluant un groupe contrôle.L’objectif de la deuxième étude était de tester les effets d’une prise en charge pluridisciplinaire de 10 mois sur l’indice de masse corporelle (IMC) et les niveaux d’AP d’adolescents obèses (21 garçons et 41 filles âgés de 14 ans avec un IMC de 33 kg/m²) dans un centre de Soins de Suite et de Réadaptation (SSR). Le rôle modulateur du climat parental et de la motivation de l’adolescent sur l’efficacité de la prise en charge a été évalué. Les résultats indiquent un effet positif de la prise en charge avec une diminution de l’IMC et une augmentation de l’AP au cours de la cure et quatre mois après. De type curvilinéaire, la perte de poids est forte en début de cure puis se stabilise à la fin. Le climat parental semble jouer un rôle facilitateur lors de cette amélioration, notamment par le père, lorsqu’il est perçu comme étant plus chaleureux, plus impliqué et soutenant davantage l’autonomie. Ces programmes de promotion de l’AP génèrent des résultats prometteurs sur les niveaux d’AP des adolescents. Cependant, l’étude des déterminants du maintien des changements obtenus pendant les interventions doit être poursuivieThis thesis is based on the observation of the lack of physical activity (PA) in adolescents: approximately 80% of this age group does not reach the recommended daily 60 minutes. This situation and its important health consequences, has a greater impact on the most vulnerable young people, such as obese adolescents and those from socioeconomically disadvantaged families. Two studies aiming at promoting PA to these audiences were conducted: objective measures of PA before, during and after interventions were performed in two different PA program settings.The goal of the first study was to test the feasibility and the impact of a PA program for adolescents from disadvantaged backgrounds. For each adolescent, one of their parents was also involved. Thus, 18 parents and 22 adolescents participated in the “1 parent - 1 adolescent” program. Two hours of PA twice a week during eleven weeks were proposed for each of the participating groups. PA levels and several anthropometric, physiological and psychological parameters were collected. All participants followed the eleven weeks of intervention. The analyzes showed that the daily 60-min AP threshold was reached only during the program for adolescents. The daily 30 min for parents was reached at all measurements times of. Additional analyzes revealed 1) that program efficacy on PA level was modulated by age for adolescents and by attendance rate for parents, 2) a decreased of amotivation for the most assiduous adolescents, and 3) an increase in well-being for adolescents. The results of this pilot study highlighted the feasibility and effectiveness of such a program, which could now be deployed in the form of a randomized trial including a control group.The goal of the second study was to test the effects of 10-month multidisciplinary residential weight reduction program on body mass index (BMI) and PA levels of obese adolescents (21 boys and 41 girls aged 14 years with a BMI of 33 kg / m²). The modulating role of parental climate and motivation of the adolescent on the effectiveness of the care was evaluated. The results indicated a positive effect of the program with a decrease in BMI and an increase in PA during the course of treatment and four months after. With a curvilinear shape, the weight loss was strong at the beginning of the cure and then stabilized at the end. The parental climate seemed to play a facilitating role in this improvement, especially by the father, when he was perceived as being warmer, more involved and more supportive of autonomy. These PA promotion programs generate promising results on adolescent PA levels. However, the study of the determinants of the maintenance of changes during interventions must be continued

Abstract:
Les enjeux de santé publique auxquels nos systèmes de santé et éducatif ont à faire face nécessitent des transformations qui passent notamment par le développement d’interventions en santé des populations (actions, programmes, organisations, politiques). Ces interventions sont généralement considérées comme complexes. La complexité est un enjeu majeur pour l’évaluation des interventions. Si les devis expérimentaux sont les références pour la recherche clinique, leur contrôle des facteurs contextuels pour renforcer la validité interne des études, obère la validité externe de ces recherches. Il convient d’aller au-delà de ces designs centrés sur l’efficacité, afin de comprendre les mécanismes et processus de l’intervention. Cette approche doit permettre d’examiner la mise en oeuvre et les conditions de routinisation, de transférabilité et de mise à l’échelle de l’intervention, dans le monde réel. Dans cette perspective, Chen a proposé un changement de paradigme en développant le modèle de la validité intégrative. Dans une approche ascendante, celui-ci reconnait 3 types de validité : la validité interne, la validité externe et la validité viable. La validité viable s’intéresse à l’intégration des interventions dans le système dans lequel elle vise à être déployées, hors d’un contexte de recherche. La validité viable correspond à la perception des parties prenantes quant à savoir si une intervention est utile, appropriée, faisable, abordable, adaptée et évaluable, dans le monde réel (Chen, 2010). Cette thèse s’intéressait à la pertinence de l’approche ascendante pour les interventions en santé des populations et au concept de viabilité : Quelle est la place de la viabilité dans le développement et l’évaluation d’interventions complexes en santé des populations ? En quoi l’étude de la viabilité est un préalable pour envisager la pérennisation, le transfert et la mise à l’échelle de l’intervention ? Quels sont les critères (et dimensions) à considérer pour analyser la viabilité ? L’objectif était d’analyser la viabilité d’interventions innovantes à partir du vécu de l’intervention par les parties prenantes. Une stratégie d’étude de cas multiples, mobilisant des méthodes qualitatives, suivant plusieurs niveaux d’analyse imbriqués a été choisie. Les trois cas ont été sélectionnés au regard de points de similitudes (ex : intervention dans le champ de la petite enfance) et de contrastes. Les résultats étaient en convergence avec les postulats de Chen quant à la pertinence d’adopter une approche ascendante en recherche et de s’intéresser à la validité viable. Elle proposait de décrire la viabilité comme le potentiel d’une intervention innovante : (i) à s’intégrer dans les projets, programmes, organisations, politiques existantes afin de former un tout cohérent en termes d’objectif, de missions des parties prenantes, de leviers d’interventions et de moyens ; et (ii) à faire sens pour les parties prenantes de l’intervention dans le monde réel. Ce « faire sens » dépendait de l’adéquation entre la perception des parties prenantes de l’intervention innovante et du système dans lequel elles évoluent. Les résultats ont permis d’éprouver les critères de viabilité tels que mis à jour par Chen en 2023 et de les décliner en dimensions. Ils ont mis en avant l’interdépendance de la perception de ces critères par les parties prenantes qu’ils soient liés à la nature ou à la faisabilité de l’intervention. En outre la viabilité est située : il s’agissait de s’intéresser aux conditions de viabilité plus que de proposer une vision binaire de la viabilité. Différents déterminants de la viabilité ont été identifiés : les composantes du changement organisationnel et les niveaux de l’approche socio-écologique. Finalement, cette thèse a permis d’interroger la définition d’une intervention probante sous le prisme de la viabilité. Des recherches complémentaires sont en cours pour interroger le concept dans une perspective interdisciplinairePublic health challenges facing our healthcare and education systems call for transformations that include the development of population health interventions (actions, programs, organizations, policies). These interventions are generally considered to be complex. Complexity is a major issue for the evaluation of interventions. While experimental designs are the gold standard for clinical research, their control of contextual factors to reinforce the internal validity of studies obviates the external validity of such research. It's essential to go beyond these efficacy-focused designs, in order to understand the mechanisms and processes of the intervention. This approach should make it possible to examine the implementation and conditions of routinization, transferability and scaling-up of the intervention, in the real world. To this end, Chen proposed a paradigm shift by developing the integrative validity model. This bottom-up approach recognizes 3 types of validity: internal validity, external validity and viable validity. Viable validity concerns the integration of interventions into the system in which they are to be deployed, outside a research context. Viable validity corresponds to stakeholders' perception of whether an intervention is useful, suitable, practical, affordable and evaluable, in the real world (Chen, 2010). This PhD explored the relevance of the bottom-up approach to population health interventions and the concept of viability: What is the place of viability in the development and evaluation of complex population health interventions? In what way is the study of viability a prerequisite for considering the sustainability, transfer and scaling-up of interventions? What criteria (and dimensions) should be considered when analyzing viability? The aim was to analyze the viability of innovative interventions based on stakeholders' experience of the intervention. A multiple-case study strategy, mobilizing qualitative methods and following several interlocking levels of analysis, was chosen. The three cases were selected on the basis of similarities (e.g.: intervention in the field of early childhood) and contrasts. The results converged with Chen's postulates on the relevance of adopting a bottom-up approach to research and focusing on viable validity. They suggested describing viability as the potential of an innovative intervention: (i) to integrate with existing projects, programs, organizations and policies to form a coherent whole in terms of objective, stakeholder missions, intervention levers and inputs; and (ii) to make sense to the intervention's stakeholders in the real world. This "making sense" depended on the fit between the stakeholders' perception of the innovative intervention and the system in which they are evolving. The results made it possible to test the viability criteria as updated by Chen in 2023 and to decline them into dimensions. They highlighted the interdependence of stakeholders' perceptions of these criteria, whether related to the substance or feasibility of the intervention. Moreover, viability is situated: the aim was to focus on the conditions of viability rather than to propose a binary vision of viability. Various determinants of viability were identified: the components of organizational change, the interlocking levels of the socio-ecological approach. Finally, this research questioned the definition of a evidence-based intervention through the prism of viability. Further research is underway to examine the concept from an interdisciplinary perspective

Abstract:
Mestrado em MicrobiologiaO HPV é o vírus sexualmente transmissível mais comum em todo o mundo, tendo uma forte relação causal com o cancro do colo do útero. A infeção por HPV é a causa necessária, mas não suficiente do cancro do colo do útero, em todo o mundo. Países em desenvolvimento têm maior taxa de infeção por HPV e cancros relacionados sendo que a prevalência da infeção por HPV global varia por país, região dentro do mesmo país e subgrupo da população sendo que os genótipos de HPV podem apresentar diferentes distribuições de acordo com a região geográfica. Mulheres africanas são desproporcionalmente afetadas com HPV e têm uma maior taxa de morbidade de cancro do colo do útero. Devido à falta de conhecimento sobre o HPV, são necessários rastreios, medidas preventivas relacionadas com cancros do colo do útero, programas de tratamento, acompanhamento posterior e imunização com vacinas contra o HPV. O objetivo deste trabalho foi determinar a prevalência da infeção por HPV e caracterizar a frequência dos vários genótipos de HPV numa população de mulheres angolanas, usando a Polymerase Chain Reaction (PCR), Restriction Fragment Length Polymorphism (RFLP) e realizar uma revisão sistemática sobre a prevalência e distribuição genotípica de HPV no continente africano. Os resultados mostram que a prevalência de HPV em mulheres angolanas foi 20,9% (14/67), que foi muito baixa em comparação com outros países da África Central. Os genótipos mais prevalentes foram HPV-61 (35.7%), HPV-16 (14.3%), HPV-33, -56, -58a, -58b, -70c, -72, -84 (7,1%). Também se verificou que dentro de regiões geográficas africanas podemos esperar diferentes taxas de eficácia resultantes de uma vacinação das populações utilizando as vacinas atualmente existentes. Em conclusão, este estudo fornece as primeiras estimativas da prevalência de HPV e sua distribuição entre as mulheres angolanas, demonstra que a epidemiologia da infeção por HPV em Angola é diferente de outras regiões do mundo. Sendo que vacinação específica para cada área geográfica é necessária, para evitar doenças relacionadas com o cancro do colo do útero e outras doenças relacionadas com o HPV. Os diferentes dados observados entre nosso estudo e os estudos utilizados para comparar os resultados podem refletir a diferenças na distribuição dos tipos HPV em diferentes populações ou podem ser por causa de diferenças entre a sensibilidade dos métodos utilizados.
Worldwide HPV is the most common sexually transmitted virus that has a strong causal relationship with cervical cancer (CC). Persistent HPV infection is the necessary but non-sufficient cause of CC worldwide. Developing countries have the highest burden of HPV infection and related cancers and the prevalence of HPV infection overall varies by country, region within country, population subgroup and HPV genotypes may exhibit differing distributions according to geographic region. African women are disproportionately impacted with HPV and have a higher rate of morbidity of cervical cancer. Due to lack of knowledge about HPV, smears and cervical cancer-related preventive measures, treatment adherence and follow-up and immunization programs of HPV vaccines are needed. The aim of this work was determine the prevalence of HPV infection and characterize the frequency of multiple HPV genotypes in Angola using Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) and to perform a systematic review on the prevalence and genotypic distribution of HPV in the African continent. The results show that HPV prevalence in Angolan women was 20.9% (14/67) which was very low compared with other countries of Central Africa. The most prevalent genotypes were HPV-61(35.7%), HPV-16(14.3%), HPV-33, 56, 58ª, 58b, 70c, 72, 84 (7.1%). It also shows that within African geographic regions we may expect different rates of efficacy resulting from a putative vaccination of populations using the currently existing vaccines. In conclusion, this study provides the first estimates of the prevalence of HPV and distribution among women from Angola and demonstrates that the epidemiology of HPV infection in Angola is different from that of other world regions. Specific area vaccinations are needed to prevent cervical cancer and the other HPV- related diseases. The observed different data between our study and the studies used to compare the results might reflect true differences in the distribution of HPV types in different populations or might be because of differences in the sensitivity of the methods used.

Abstract:
Thesis advisor: Thomas M. CreaChild sexual abuse is a major public health problem in the United States, but identifying risk, especially in young children with suspicion of abuse, poses many challenges. The aim of this study is to understand how clinicians judge the possible presence of sexual abuse in children where serious suspicion exists but without substantiated abuse. This study used data from randomly selected sexual abuse and trauma evaluations of preschool and school-aged children presenting to Boston Children’s Hospital (BCH) Outpatient Child Protection Program between 2000-2007 (N=100) to examine the association between child and family risk factors and level of clinician concern regarding likelihood of child sexual abuse. Multi-nomial logistic regression analysis was used to examine the relationship between child and family risk factors and level of clinician concern regarding suspicion of abuse, moderated by child’s gender and age. Results indicated that a child’s disclosure and trauma presentation were the key factors that clinicians considered within the higher level of clinician concern regarding likelihood of sexual abuse. Implications for future research and clinical practice include attention to methodology research to assist with the development and validation of assessments for evaluation of risk in complex cases of suspicion of sexual abuse that can be offered in clinical setting, without sole reliance on the child’s ability to disclose in order to access help. Additionally, it is essential that research focuses on the development of clinical models to help with clinical decision making protocols in ambiguous cases of sexual abuse with children who may not be in a position to disclose, but serious concerns have been raised, with focus on increasing their safety. The findings in this research strongly suggest that it is essential to continue to focus on assisting children who present with suspicion of sexual abuse in complex cases that do not fit neatly into our current forensic and child protective services systems. This is especially necessary with the most vulnerable children where disclosure is unlikely, but clinical evaluations can yield recommendations that maximize efforts at increasing safety, child mental health, and family cohesion, and build on strengths while simultaneously accounting for risks

Abstract:
This study was a pilot investigation of the initial validity of a newly developed behaviour-screening instrument for early intervention service providers. Group Special Education, Early Intervention (GSE/EI) (2005) adapted the Canterbury Behaviour Screening Protocol (CBSP) from a widely used behaviour-screening instrument the Early Screening Project. The CBSP consisted of 49 items in 2 checklists. GSE/EI identified 10 early childhood centres with a total roll of 712 to participate in the study. Staff were asked to categorise children's problem behaviours as either withdrawn/isolated or aggressive/oppositional, using profiles provided. Next, they were asked to nominate 2 children in each category, and an additional 2 children in either category, and to rank them from most concerning to least concerning. Centres identified 25 children in the withdrawn/isolated category, and 28 children in the aggressive/oppositional category. Staff completed checklists for children with parent/carer consent, which were scored according to preset protocols. Scores on the CBSP were assigned risk values ranging from "extreme" to "no risk". The estimated prevalence of "high" to "extreme" behaviour problems was 7.2% based on CBSP protocols and teacher nominations. The level of agreement between teacher rank and CBSP score was 79%, and this determined the initial specificity. Next, independent observations of the behaviour of the nominated children were conducted during free play periods at the centres by an observer blind to the children's nominated category, teacher ranking or checklist score. Risk levels were assigned based on the observation scores, using a cut-off value of 37% time spent in problem behaviour for girls and 40% for boys. There was agreement in terms of teacher rank and observation scores, (categorised into either "no risk" and "at/high/extreme risk) for 65% for children in the withdrawn/isolated category, and 75% for children in the aggressive/oppositional category. The level of agreement between the CBSP score and the observations (categorised into either "no risk" or "at/high/extreme" risk) was 40% for children in the withdrawn/isolated category, and 46% for children in the aggressive/oppositional category. Using the cut-off values, a prevalence estimate for high risk or extreme risk for behaviour disorders, based on independent observation of children, was 3.2%. Centre staff completing a feedback form determined the social validity of the CBSP. Although responses were generally favourable, a number of suggestions were also made to improve the procedure. Despite limitations in the design of the draft, the CBSP shows promise for a first step in a screening procedure designed to screen New Zealand early childhood centres for children who may be at risk for developing behaviour and/or social emotional problems. The independent observation may also be useful as a second step, prior to extensive eligibility assessment. A number of suggestions were made for future drafts such as addressing the limitations specified, conducting the CBSP with a greater number of children, and determining the concurrent validity, and test-retest reliability.

Abstract:
Bakgrund.Ländryggssmärta förekommer hos piloter och kan eventuellt vara en anledning till framtida långtidssjukskrivningar. Möjliga påverkande faktorer är antal yrkesverksamma år och träningsvanor. Det finns få antal studier gjorda på kommersiellt flygande piloter. Syfte.Att kartlägga förekomsten av ländryggssmärta hos piloter inom kommersiell luftfart samt undersöka risken för långtidssjukskrivning. Vidare kartlägga skillnader i förekomst av ländryggssmärta hos piloter som arbetat <10 respektive >10 år samt att undersöka sambandet mellan ländryggssmärta och självskattad träningsvana. Metod.En tvärsnittsstudie genomfördes med webbenkät. Enkäten bestod av ett antal inledande egendesignade frågor och därefter följde Örebroformuläret kortversion av Steven Linton. Resultat.Antalet deltagare i studien var 73 respondenter vilket motsvarar en svarsfrekvens på 30 %. Totalt 57.5 % av de 73 respondenterna angav sig ha ländryggssmärta, av dessa hade majoriteten besvärats av smärtan i över ett år. Resultaten visade på att de piloter som hade ländryggssmärta inte hade en ökad risk för långtidssjukskrivning men att det fanns en skillnad i förekomst av ländryggssmärta hos de som arbetat över respektive under tio år (p=0.017). Korrelationen mellan träningsvanor och förekomst av ländryggssmärta var inte statistiskt signifikanta (r=0.03), (p=0.80). Konklusion.Prevalensen av ospecifik ländryggssmärta hos kommersiellt flygande piloter var hög och föreföll att öka med antalet yrkesverksamma år. Ytterligare forskning behöver undersöka vilka faktorer som bidrar till den höga förekomsten av ospecifik ländryggssmärta.Background.Low back pain is common among commercial flying pilots and may possibly be a reason for future long- term sick leave. Possible influencing factors are the number of working years and exercise habits. There are few studies researching commercial flying pilots. Purpose.To describe the prevalence of low back pain among commercial flying pilots and to investigate the risk of long- term sick leave. Furthermore, identify differences in the incidence of low back pain among pilots who has worked <10 compared to >10 years, as well as to investigate the correlation between low back pain and self-assessed exercise habits. Method.A cross-sectional study was conducted with a web survey. The survey initially consisted of self-designed questions followed by “Örebroformuläret kortversion” by Steven Linton. Results.The study contained 73 respondents, which corresponded to a response rate of 30%. A total of 57.5% of the 73 respondents indicated that they had low back pain, of which the majority had been suffering for over a year. The results showed that the pilots who had low back pain had no risk of long-term sick leave. There was a difference in the incidence of low back pain in those who worked over compared to under ten years (p=0.017). The correlation between exercise habits and the incidence of low back pain was not statistically significant (r=0.03), (p=0.08). Conclusion.The prevalence of nonspecific low back pain in commercial flying pilots was high and seemed to increase with the number of working years. Further research needs to investigate which factors contribute to the high incidence of nonspecific low back pain.

Abstract:
In application, ADS-33E-PRF provides the means to effectively predict rotorcraft handling qualities via validated criteria and demonstrate actual handling qualities in flight test using mission task elements (MTE). With decades of successful outcomes achieved by integrated industry and government test teams, international users, and researchers, this approach provides an effective means to evaluate handling qualities of advanced rotorcraft designs. The requirement for at least three test pilot evaluators of each MTE expands the flight hours required for test and hence increases costs. To reduce flight hours required, while maintaining process effectiveness, the Naval Air Warfare Center Aircraft Division (NAWCAD) is interested in better understanding the relationship between pilot workload and assigned handling qualities ratings such that predictive tools, if proven effective, can reduce this burden. To meet this challenge, Systems Technology, Inc. (STI), Charles River Analytics, Inc. (CRA), Mitchell Aerospace Research, and Advanced Brain Monitoring, Inc. joined with NAWCAD to explore through piloted simulation the relationship between physiological measures of pilot workload and assigned pilot ratings as experienced test pilots conducted handling qualities evaluations using three exemplar MTEs. This paper describes the piloted simulation study and summarizes initial results.

Abstract:
This work presents the results of a piloted flight simulator campaign aimed at measuring biomechanical performance indicators - upper limbs motion and electromiography of main muscle bundles - of pilots performing complex, realistic tasks. Ship deck landings performed by a single pilot, flying several helicopter configurations with sea conditions of increasing intensity have been considered. The analysis of the results shows an increase in muscular activity in relation with the increase in task difficulty, in agreement with subjective ratings (Bedford workload scale). The study provided useful indications to improve the corresponding biomechanical simulations, as well as to characterize pilot performance during specific tasks.

Abstract:
With the move towards fly-by-wire flight control systems for rotorcraft, pilot inceptors are no longer physically connected to the mechanical hardware of the aircraft. This has allowed the move to smaller, lighter, side-mounted controllers, which typically lack a mechanical connection between the pilots' inceptors. Such controllers can be electronically linked using active inceptors, however this adds cost and weight over passive inceptors. The objective of the work presented in this paper is to assess the impact of linked versus unlinked cyclics on Army helicopter aircrew coordination. To do this, a piloted simulation was conducted in the NASA Ames Vertical Motion Simulator using both Mission Task Element type maneuvers, as well as more operationally relevant mission vignettes. The simulator was configured with two side-by-side pilot stations with sidestick controllers which could be configured to operate in either a linked or unlinked configuration. During each task, a control transfer from the pilot flying to the pilot not-flying was either forced or induced, and subsequently the pilots were asked to answer a series of questions and rating scales related to predictability, awareness, and acceptance. Results of the study showed that in all cases, pilots preferred the linked cyclic controller configuration, which received better predictability, awareness, and acceptance ratings. In addition, the linked cyclic controller configuration had shorter-duration simultaneous input events (both pilots moving their inceptors to control the aircraft at the same time) compared to the unlinked cyclic controller configuration.

Abstract:
Adaptive learning capabilities based on Artificial Intelligence (AI) can provide learners with a personalized learning path. It is a capability that customizes the trainee’s learning experience to their identified learning style and preference while providing the quickest route through the pilot training program. To accomplish this, every training program should be integrated to provide context and relevance and improve performance by generating insights on the performance of learners or cohorts and the efficacy of associated content. The aviation industry seeks novel methods for pilot training that are more efficient. Competency-Based Training and Assessment (CBTA) is a method that proposes an assessment process that helps understand how a flight crew may be able to manage both foreseen and unforeseen incidents and uses this data to help the crew achieve a higher level of efficiency.With a centralized data capture process centered on the pilot’s information, a pilot profile can be created to provide personalized training and advanced insight into the pilot’s learning experience. New technologies like Virtual Reality (VR) training combined with biometric data like eye-tracking and facial tracking can be a powerful platform to obtain the required data. Describing the communication competency from a training perspective, an AI – VR training environment (Simulated Air Traffic Control Environment - SATCE) would allow the pilots to improve their communication skills, enable pilots to ask questions with a specifically trained Generative Pre-Trained (GPT) model, and receive a validated answer. The Purdue case study focuses on the cognitive aspects of flight training using emerging technologies. This research aims to improve training effectiveness by incorporating immersive technologies in aviation training. Dynamic real-time visualization, automatic human profile assessment, and training system adaption technologies can potentially improve flight training’s overall efficacy and efficiency. This digitization process includes various immersive virtual technologies and synthetic learning environments. By using these technologies, all persons participating in flight training will obtain a complete insight into the participants’ performance cognitive limitations, ultimately optimizing the training lifecycle.

It is a capability that customizes the trainee's learning experience to their identified learning preference while providing the quickest route through the pilot training program. To accomplish this, the training design and process is supported by cognitive theories, providing a succession of contextualized recommendations based on the training program goals and learner performance. The aviation industry seeks novel methods for pilot training that are more efficient. Competency-Based Training and Assessment (CBTA) is a method that proposes an assessment process to help understand how a flight crew manages both foreseen and unforeseen incidents, and uses this data to help the crew achieve a higher level of efficiency and performance. By training pilots in a virtual environment, instructors introduce evidence-based scenarios testing the pilot's performance while collecting relevant data. Biometric data allows for accurate training and assessment of pilot behaviors and performance parameters in competencies like, but not limited to, application of procedures, proper use of automation, manual flying, communication, workload management, situation awareness, decision making, and resilience. Considering communication competencies from a training perspective, AI (Virtual Reality - Simulated Air Traffic Control Environment; VR-SATCE) would allow pilots to improve their communication skills, enable pilots to ask questions with a specifically trained Generative Pre-Trained Transformer (GPT) model, and receive a validated answer. The virtual instructor updates the training scenarios in real-time and corrects the trainees instantly during the training session – in the same or better and safer way an experienced Type Rating Instructor would. Moreover, the same AI crewmember – a virtual instructor – can also function as an uncooperative co-pilot, which will enhance the student's training in managing difficult situations when lacking support from team members. The Purdue School of Aviation and Transportation Technology (SATT) case study focuses on the cognitive aspects of flight training using immersive technologies. This research aims to improve training effectiveness by incorporating immersive technologies in aviation training. Dynamic real-time visualization, automatic human (pilot) profile assessment, and adaptive training system technologies can potentially improve flight training's overall efficacy and efficiency. By using these technologies, all persons participating in flight training will obtain comprehensive insight into the participants' performance and cognitive limitations, ultimately optimizing the training lifecycle.

Abstract:
This paper describes the development and implementation of newly designed helicopter ship deck landing control modes and their evaluation in a piloted simulation study. The ship deck landing modes are embedded in a model following controller architecture. The employed control design is a complete model-following control system which imposes the desired command model dynamics on the controlled helicopter. Different command types combined with various hold functions are implemented to make the task easier for the pilots. Three basic command types and three advanced command types, one without ship communication and two with ship communication, are implemented. A piloted simulation study was performed in a simulator to evaluate and compare the implemented control modes within a complete maritime scenario design. The evaluation of control modes is based on the success of helicopter ship deck landings which is assessed by a quantitative as well as a qualitative assessment. Simulation results demonstrate that the advanced command types improved the task performance as well as reduced the pilot workload extensively in comparison to the basic command types.

Abstract:
Accurate knowledge management is vital for an organization to perform well. Managing explicit knowledge is relatively easy but managing tacit (implicit) knowledge is not. Effective transfer of tacit knowledge from experts to novices in an organization is therefore essential. Maritime pilotage is a safety-critical operation in which pilots use their expertise to guide vessels in specific waters. The purpose of this study is to improve the Pilot Training Programme (PTP) run by the Swedish Maritime Administration (SMA). The aim of this study is to evaluate and describe the prevailing methods of transferring tacit knowledge during the PTP. This study includes 20 maritime pilots and covers a complete PTP. A qualitative mixed-methods approach was used, based on activity theory and including observations, interviews, questionnaires, and document analyses. The results showed that tacit knowledge transfer during the PTP occurs during situated learning, such as apprenticeships, hands-on learning and communities of work. However, the transfer methods are not sufficiently documented from a didactic perspective.

"Method for Predicting Multi-Axis Task Performance and Handling Qualities Rating for a Coaxial-Compound and Tiltrotor Rotorcraft with Validating Data." In Vertical Flight Society 79th Annual Forum & Technology Display. The Vertical Flight Society, 2023. http://dx.doi.org/10.4050/f-0079-2023-18069.
Abstract:
The Cooper-Harper scale provides a structured approach for assessing handling qualities. It ties performance and relative pilot workload to the Handling Qualities Rating (HQR) of a task such that neither one, in isolation, is used to assess handling qualities. Prior work demonstrated that the Spare Capacity OPerator Estimator (SCOPE), whose elements derive from tracking error and pilot control motion, could predict HQR and performance for a single-axis task by applying a model of pilot control and an objective function driving pilot behavior to establish reference workload associated with Level 1 and Level 2 handling qualities. Level 1 workload is generated using elementary vehicle dynamics for executing the task. Level 2 workload is generated using vehicle dynamics that are degraded to produce a response coinciding with the adequate performance criteria. This method of workload calibration avoids using training data collected from pilots. The work presented in this paper extends SCOPE's single-axis predictive capabilities to multi-axis coupled control using the same perceptual principles used in SCOPE, where individual stimuli are perceived collectively as the product of their logarithms. SCOPE's predictive performance and HQR estimates were tested using data from a high-fidelity piloted simulation study for a variety of evaluation tasks using two representative Future Vertical Lift rotorcraft configurations (a lift offset coaxial helicopter with a pusher propeller and a tiltrotor). The SCOPE derived estimates compared favorably with the pilot performance and ratings from the simulation study.

Abstract:
The benefits of developing objective measures of handling qualities, more specifically pilot workload, are of great interest to the United States Navy. Several lines of research have been initiated to that end with this study focusing on inceptor activity. Potential pilot inceptor workload metrics were applied to a data set consisting of ten pilots conducting simulated approach and hover tasks to a DDG-class ship. Piloted handling qualities ratings were recorded for the tasks. Workload variation was induced by using different aircraft response types, varying degrees of ship motion, and the presence/absence of cueing. Using only pilot inceptor state data, potential workload metrics were evaluated and correlations with handling qualities ratings were examined. Methods to apply traditionally single-axis metrics to multi-axis tasks were explored, inconclusively. Predictive ability of the simple metrics improved by breaking tasks into pseudo-time invariant sub-tasks. A multi-axis metric from past research was shown to correlate best with workload ratings, but several more traditional workload measures show promise and correlation may improve if applied to a scale other than Cooper-Harper. A novel approach of treating the multi-axis problem as a metric itself is introduced and data presented to support adoption as a workload discriminator in and of itself.

Abstract:
Mobile Bay is a large estuary located in the southwest corner of Alabama, which connects to the Gulf of Mexico. Mobile Harbor contains the only port in the state that supports ocean-going vessels. Some of the larger vessels calling on the port experience transit delays and limited cargo capacity, so a study was conducted by the US Army Corps of Engineers, Mobile District (CESAM), and the Alabama State Port Authority to investigate channel improvements. In 2017, the US Army Engineer Research and Development Center (ERDC) assisted CESAM in screening proposed deepening and widening alternatives in Mobile Bay by completing a Feasibility Level Ship Simulation (FLSS) study using the ERDC Ship/Tow Simulator. These lower-resolution databases from the FLSS study were used as a foundation to complete a more robust navigation study in 2020 to test the proposed modifications to Mobile Harbor. During this study, three main areas were focused on: a bend easing, a passing lane, and a turning basin. Testing of the proposed design was evaluated over the course of 2 weeks with eight pilots. Assessment of the proposed modifications was accomplished through analysis of ship simulations completed by experienced local pilots, discussions, track plots, run sheets, and final pilot surveys.
