Exploration des interactions de l’étudiant-athlète commotionné et de son réseau de soutien social pendant sa convalescence et son retour au jeu

Mémoire en recherche-sciences de l'activité physiqueLes étudiants-athlètes universitaires ayant subi une commotion cérébrale liée au sport peuvent éprouver de nombreux symptômes, y compris des implications psychosociales telles que la frustration, la colère, l'isolement, l'anxiété et la dépression. Nous savons encore peu de choses sur la façon dont le soutien social est communiqué aux étudiants-athlètes et interprété par eux. Cette étude de cas qualitative a tenté de mieux comprendre ces interactions. Nous avons étudié six cas, chacun composé d'un étudiant-athlète ayant subi une commotion cérébrale (n = 6 ; M = 21,5 ans, durée moyenne de la commotion = 9,8 mois, intervalle de 3 à 18 mois) et de 2 ou 3 membres de son réseau de soutien social (n = 16 ; M = 31 ans, intervalle de 18 à 64 ans). Chaque étudiant-athlète a participé à deux entrevues semi-structurées (M = 65min, intervalle = 34-102min) et chaque membre du réseau de soutien social a participé à un entretien (M = 36min, intervalle = 23-53min). Chaque participant a également rempli une frise chronologique pour détailler l'évolution du soutien social (reçu et fourni) tout au long du rétablissement de l'étudiant-athlète. Les données ont été analysées en utilisant les six phases de l'analyse thématique. Les résultats de cette étude montrent que les interactions des étudiants-athlètes pendant leur convalescence sont motivées par leur peur de l'isolement. De plus, les étudiants-athlètes ayant subi une commotion cérébrale interagissaient principalement avec leur home network et leur treatment network pendant la rehabilitation phase de leur convalescence. Enfin, certaines interactions des étudiants-athlètes avec d’autres individus (ex., professeures, membres de la famille) peuvent avoir un impact négatif sur leur convalescence. Cette étude fournit de nouvelles informations sur l'impact du soutien social chez les étudiants-athlètes pendant leur convalescence après une commotion cérébrale.University student-athletes who have suffered a sports-related concussion may experience many symptoms, including psychosocial implications such as frustration, anger, isolation, anxiety, and depression. We still know little about how social support is communicated to and interpreted by student-athletes. This qualitative case study attempted to better understand these interactions. We studied six cases, each consisting of a concussed student-athlete (n = 6; M = 21.5 years, mean concussion duration = 9.8 months, range 3-18 months) and 2-3 members of their social support network (n = 16; M = 31 years, range 18-64 years). Each student-athlete participated in two semi-structured interviews (M = 65min, range = 34-102min) and each member of their social support network participated in one interview (M = 36min, range = 23- 53min). Each participant also completed a timeline to detail the evolution of social support (received and provided) throughout the student-athlete's recovery. Data were analyzed using the six phases of thematic analysis. The results of this study show that student-athletes' interactions during recovery are driven by their fear of isolation. In addition, concussed studentathletes interacted primarily with their home network and treatment network during the rehabilitation phase of their recovery. Finally, some of the student-athletes' interactions with other individuals (e.g., professors, family members) may have a negative impact on their recovery. This study provides new information on the impact of social support among studentathletes during their recovery from concussion

COMPARISON ON THE EFFECTS OF DIFFERENT FIBERS ON SELF-COMPACTING CONCRETE

The project is intended to develop cost effective of Self- compacting Concrete (SCC) .Nowadays, the construction industry in Malaysia as well as in all over the world is looking for more economical construction materials. In addition, the existing of self-compacting concrete is facing brittleness problem due to their high binder (powder) content and low aggregate amount. Hence, the aim objective of this research is to investigate the effect of different fibers on properties of self-compacting concrete. The aim is supported by two sub-objectives which are to compose the effect of Copped Basalt Fiber (CBF) and Polyvinyl Alcohol Fiber (PVA) with addition of Fly ash (FA) as the filler material on compressive and tensile strength, and to investigate and compare the effect of PVA, CBF on the workability characteristic of SCC. This study can satisfy the requirements of construction standards of self-compacting concrete found in both European Federation of National Associations Representing for Concrete (EFNARC) and Japan Society of Civil Engineers (JSCE). To achieve the research objectives there are different concrete mix has been prepared in UTP concrete laboratory. Experimental work consists of 90 cubes of size 100mm3, 10 cylinders of size 100 x 200 mm2, and 10 beams of 100 x 100 x 500 mm3. The compressive strength was tested for 7days, 28days, and 56days while the splitting tensile and flexural strengths were cast only for 28-days. The concrete mix used in this experimental study formed into two groups of concrete mix. The firs group consists of 100% OPC, while the second group consists of 70% OPC and 30% Fly ash. In each of the above groups different percentage of fibers i.e. 1% and 2% was added and the characteristics of fresh and hardened concrete were investigated. The research project showed that the fibers have slight effect of the fresh properties as well as hardened properties of self-compacting concrete mix (SCC)

Méningite à Streptococcus pneumoniae sérotype 7A chez un nourrisson immunisé par deux doses du vaccin pneumococcique conjugué 13-valent: à propos d’un cas

Cause majeure de morbidité et mortalité, les méningites à pneumocoque (PNO) représentent un fléau mondial. Au Maroc, le vaccin conjugué 13-valent contre le pneumocoque (PCV13) a été introduit dans le Programme National de Vaccination en octobre 2010 selon le calendrier 2 + 1 et remplacé par le PCV10 en juillet 2012, selon le même calendrier. Malgré le recours au PCV13, essentiel dans la lutte contre les maladies pneumococciques, l'émergence de nouveaux sérotypes non vaccinaux entrainent toujours des méningites chez l'enfant et engendrent de lourdes séquelles. Nous rapportons le cas d'une méningite causée par Streptococcus pneumoniae sérotype 7A chez un nourrisson immunisé avec 2 doses de PCV13. La particularité de cette observation réside dans une méningite à PNO sérotype 7A, non contenu dans le PCV13, chez un nourrisson vacciné par 2 doses du PCV13. Les auteurs insistent sur la nécessité et l'importance d'un observatoire PNO et d'une large étude épidémiologique afin de déterminer les sérotypes en circulation au Maroc depuis l'introduction du PCV13 puis PCV10

Validation of the Turkish Version of the Problem Areas in Diabetes Scale

The Problem Areas in Diabetes (PAID) scale is a widely used self-report measure that can facilitate detection of diabetes-specific emotional distress in clinical practice. The aim of this study was to assess the factor structure and validity of the Turkish version of the PAID. A validation study was conducted among 154 patients with insulin-naïve type 2 diabetes. Participants completed the PAID, Centre for Epidemiological Studies Depression Scale (CES-D), Insulin Treatment Appraisal Scale (ITAS), and World Health Organization-Five Well-Being Index (WHO-5) questionnaires. Exploratory factor analyses yielded a 2-factor structure, identifying a 15-item “diabetes distress” factor and a 5-item “support-related issues” factor. The total PAID-score and the two dimensions were associated with higher levels of depression and poor emotional well-being. In the present study, the Turkish version of the PAID had satisfactory psychometric properties, however, the factorial structure was found to differ from factor solutions from other countries

A Survey on Energy Optimization Techniques in UAV-Based Cellular Networks: From Conventional to Machine Learning Approaches

Wireless communication networks have been witnessing an unprecedented demand due to the increasing number of connected devices and emerging bandwidth-hungry applications. Albeit many competent technologies for capacity enhancement purposes, such as millimeter wave communications and network densification, there is still room and need for further capacity enhancement in wireless communication networks, especially for the cases of unusual people gatherings, such as sport competitions, musical concerts, etc. Unmanned aerial vehicles (UAVs) have been identified as one of the promising options to enhance the capacity due to their easy implementation, pop up fashion operation, and cost-effective nature. The main idea is to deploy base stations on UAVs and operate them as flying base stations, thereby bringing additional capacity to where it is needed. However, because the UAVs mostly have limited energy storage, their energy consumption must be optimized to increase flight time. In this survey, we investigate different energy optimization techniques with a top-level classification in terms of the optimization algorithm employed; conventional and machine learning (ML). Such classification helps understand the state of the art and the current trend in terms of methodology. In this regard, various optimization techniques are identified from the related literature, and they are presented under the above mentioned classes of employed optimization methods. In addition, for the purpose of completeness, we include a brief tutorial on the optimization methods and power supply and charging mechanisms of UAVs. Moreover, novel concepts, such as reflective intelligent surfaces and landing spot optimization, are also covered to capture the latest trend in the literature.Comment: 41 pages, 5 Figures, 6 Tables.

Testing the effectiveness of a mindfulness-based intervention to reduce emotional distress in outpatients with diabetes (DiaMind): design of a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Approximately 20-40% of outpatients with diabetes experience elevated levels of emotional distress, varying from disease-specific distress to general symptoms of anxiety and depression. The patient's emotional well-being is related to other unfavorable outcomes, like reduced quality of life, sub-optimal self-care, impaired glycemic control, higher risk of complications, and increased mortality rates. The purpose of this study is to test the effectiveness of a new diabetes-specific, mindfulness-based psychological intervention. First, with regard to reducing emotional distress; second, with respect to improving quality of life, dispositional mindfulness, and self-esteem of patients with diabetes; third, with regard to self-care and clinical outcomes; finally, a potential effect modification by clinical and personality characteristics will be explored.</p> <p>Methods/Design</p> <p>The Diabetes and Mindfulness study (DiaMind) is a randomized controlled trial. Patients with diabetes with low levels of emotional well-being will be recruited from outpatient diabetes clinics. Eligible patients will be randomized to an intervention group or a wait-list control group. The intervention group will receive the mindfulness program immediately, while the control group will receive the program eight months later. The primary outcome is emotional distress (anxiety, stress, depressive symptoms), for which data will be collected at baseline, four weeks, post intervention, and after six months follow-up. In addition, self-report data will be collected on quality of life, dispositional mindfulness, self-esteem, self-care, and personality, while complications and glycemic control will be assessed from medical files and blood pressure will be measured. Group differences will be analyzed with repeated measures analysis of covariance.</p> <p>The study is supported by grants from the Dutch Diabetes Research Foundation and Tilburg University and has been approved by a medical ethics committee.</p> <p>Discussion</p> <p>It is hypothesized that emotional well-being, quality of life, dispositional mindfulness, self-esteem, self-care, and blood pressure will improve significantly more in the mindfulness group compared to the control group. Results of this study can contribute to a better care for patients with diabetes with lowered levels of emotional well-being. It is expected that the first results will become available in 2012.</p> <p>Trial registration</p> <p>Dutch Trial Register <a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2145">NTR2145</a>.</p
