Une perspective située pour penser l’appropriation des espaces de travail « par activités »
Authors: Lai Chiara , Ianeva Maria , Bobillier Chaumon Marc-Éric , Abitan Audrey
Published: October 2021

De plus en plus d’entreprises adoptent des formes organisationnelles flexibles, notamment à travers la mise en place d’aménagements spatiaux dits « par activités » (activity-based workspaces), qui proposent une adéquation entre l’espace et le type d’activité des travailleurs. Nous cherchons à comprendre la manière dont ces espaces et leurs caractéristiques fonctionnelles sont appropriés et intégrés dans les pratiques de leurs utilisateurs en nous appuyant sur des approches basées sur la cognition située et l’acceptation située. Notre étude s’inscrit au sein d’une filiale d’un groupe énergétique français qui a mandaté une société de conseil en immobilier pour concevoir et accompagner leur emménagement en environnement « flexible, par activités ». Notre méthodologie s’appuie sur trois journées d’observations réalisées au sein de leurs espaces de travail et de sept entretiens explicitants. Nos résultats mettent en évidence la manière dont les règles inhérentes au fonctionnement de ces espaces sont comprises et intégrées dans les pratiques des acteurs, mais aussi la manière dont ces derniers les remodèlent, les reconfigurent pour les rendre pertinentes pour leur action. Cette étude montre l’importance de fournir une compréhension plus étayée de la manière dont l’usage des espaces de travail par activités impacte et module le lien des acteurs à leur propre activité.
Activité du manager de réception à l’épreuve de la digitalisation : cas d’un projet d’accueil en mobilité dans une chaîne hôtelière internationale
Authors: Flandrin Pierre , van de Leemput Cécile , Hellemans Catherine
Published: October 2021

L’article explore l’activité du manager de proximité (MDP) dans le cadre de la digitalisation dans trois hôtels d’une chaîne hôtelière internationale. La méthodologie permet une analyse de l’activité du manager sur deux niveaux : l’activité du MDP dans son rôle de gestionnaire au quotidien en environnement digitalisé et l’activité du MDP dans l’accompagnement d’un projet pilote de digitalisation de l’accueil via le smartphone. L’analyse ergonomique montre un effet controversé des technologies avec le renforcement du cadre gestionnaire et du contrôle sur l’activité managériale. L’analyse ergonomique est également révélatrice du rôle de régulation du MDP. En contexte de changement du mode d’accueil, les résultats révèlent des tentatives d’« empowerment » du MDP pour rendre acceptable le smartphone par les réceptionnistes à travers des mises en situations destinées au développement du travail émotionnel des réceptionnistes. Ce cadre gestionnaire n’offre pas la possibilité au MDP d’être en capacité d’agir pour le développement d’un réel pouvoir d’agir des réceptionnistes avec le dispositif. Des pistes sont énoncées afin d’envisager une digitalisation source de développement de l’activité. Une d’entre elles repose sur le rapprochement des concepteurs et des usagers : managers, réceptionnistes, revenue manager autour de l’objet de la personnalisation du service. Une autre piste consiste à penser la future organisation du travail avec la technologie en amont de la conception, à travers la réalisation de simulation dynamique prenant en compte l’activité réelle à la réception.
Innovation, créativité et qualité de vie au travail : proposition et expérimentation d’un dispositif d’innovation transitionnelle
Authors: Guidou Nadège , Sarnin Philippe
Published: October 2021

Si les démarches dites de qualité de vie au travail (QVT), selon leur dénomination politique, sont décrites comme recherchant l’alliance entre les performances économiques et les performances sociales, elles suscitent encore nombre de réserves. En effet, pour que la QVT ne soit pas qu’un « glissement lexical » de plus dans le champ de la santé psychique au travail (Clot, 2019), il est nécessaire de se poser sérieusement la question des méthodologies à construire afin qu’elle réponde « aux problématiques socio-organisationnelles qui naissent de la vie de l’entreprise […] et non qu’elle vienne en surplomb constituer un énième projet à ajouter […] » (Levet, 2013, p. 104). Dans cette perspective, l’objectif de cet article est de présenter une méthodologie reposant sur des innovations organisationnelles générées à partir d’activités transitionnelles sources de créativité et de santé (Lhuilier & Roche, 2009 ; West & Far, 1990 ; Winnicott, 1999/1948). Ce dispositif, dit d’innovation transitionnelle, vise ainsi particulièrement à dépasser la difficulté à aller du diagnostic à la transformation durable et à accompagner les acteurs dans les épreuves à traverser. Il a été expérimenté pour la première fois dans un service de santé au travail qui devait intervenir au sein d’un institut de formation supérieur aux prises avec d’importants troubles psychosociaux. L’analyse de ses résultats a permis d’observer des transformations de l’organisation et des situations de travail et leur durabilité un an après la clôture du dispositif.
“Si on ne me fournit pas mes engins, après je peux plus rien faire moi” : les apports de l’analyse de l’activité à la compréhension des processus d’engagement et de désengagement au travail
Authors: Sandoval Amélie , Kostulski Katia
Published: October 2021

Cet article se propose de revisiter la question de l’engagement et du désengagement au travail, en étudiant ces derniers dans leurs liens avec l’activité de travail, telle qu’elle est quotidiennement menée par les professionnels en situation. Il mobilise pour ce faire différentes perspectives théoriques, issues de la psychopathologie et des cliniques du travail ; ainsi que des données issues d’une intervention en clinique de l’activité menée dans un service municipal de la propreté. En s’appuyant sur un exemple, il identifie une configuration particulière d’engagement et de désengagement au travail, ses liens avec l’activité, ainsi que ses implications subjectives et ses effets sur le travail.
Le territoire : un dispositif opératoire révélé par l’activité de travail
Authors: Cunha Liliana , Lacomblez Marianne
Published: October 2021

L’analyse de l’activité de travail permet de repenser le statut du territoire dans nos recherches. Car il n’est pas seulement le « sol » sur lequel l’histoire des activités de travail et de leurs protagonistes est tissée au quotidien : nous considérons en effet que le territoire est aussi un produit de l’activité, il est agi et reconstruit quotidiennement – l’activité intervient dans les processus de territorialisation. Cette perspective justifie que l’activité de travail prenne place dans les débats sur le vivre ensemble et sur les options de l’action publique dans l’aménagement du territoire. On interpelle dès lors les modes de participation publique, en revendiquant que les citoyens travailleurs y soient plus étroitement associés. Mais comment procéder ? Quelles traces permettent de démontrer l’apport de l’activité de travail aux processus de territorialisation ? Ces questions ont émergé au cours d’un programme de recherche – et nous les étayons ici en reprenant l’étude développée dans le secteur du transport collectif routier de passagers en milieu rural. L’analyse du territoire, telle que nous la concevons, est ainsi enrichie par le point de vue de l’activité et par les débats qui en émergent. Mais le territoire que nous révèle ici l’activité est surtout celui que ses protagonistes en font, au cours d’un processus de transformation trop souvent peu visible, sédimenté par nombre de répétitions silencieuses – jusqu’à devenir une ressource collective.
Faire milieu : penser l’espace du travail et de sa transformation
Authors: Robert Jeanne , Béguin Pascal
Published: October 2021

L’objectif de cet article est de discuter des concepts de « milieu » et de « faire milieu » au regard des enjeux de la conduite d’un projet territorialisé de revalorisation de la cueillette du tilleul dans les Baronnies provençales. Nous appréhendons le milieu comme une expression de la normativité du vivant, qui se forme par un travail de mise en correspondance de phénomènes environnementaux multiples et hétérogènes pour se maintenir en vie. Ce « faire milieu » s’exprime dans l’histoire de la cueillette du tilleul, dans les gestes du travail des négociants et des cueilleurs. Il en émerge un tissu vivant de liens qui déborde largement les limites d’un territoire administratif. Dans le cadre d’un projet de revalorisation de cette filière (qui a traversé des crises mortifères), la question soulevée est alors d’identifier comment on peut conduire un projet territorialisé de manière à faciliter et soutenir cette nécessité de tisser des liens et de créer un milieu.
Résumé de thèse. Les dynamiques d’engagement et de désengagement au travail
Authors: Sandoval Amélie
Published: October 2021

Cette thèse porte sur l’engagement et le désengagement au travail, qu’elle propose de conceptualiser comme des dynamiques singulières et parfois paradoxales de mobilisation de soi dans l’activité, liées au contexte organisationnel et institutionnel dans lequel elles se déploient, et pouvant varier en fonction des moments, des situations et des personnes.
Les sources de l’or du décor entre Orient et Occident (ive-xiie siècles)
Authors: Neri Elisabetta
Published: October 2021

Cet article s’interroge sur la source de l’or employé dans les mosaïques à fond d’or. Plusieurs arguments historiques et techniques suggèrent l’utilisation des monnaies pour battre les feuilles d’or utilisées dans les tesselles. Non seulement la dynamique de circulation de l’or, fortement contrôlée, mais aussi les quantités relativement importantes d’or utilisée dans les décorations et les indications des recettes techniques permettent de supposer l’utilisation de l’or monétaire pour produire les feuilles d’or. L’analyse archéométrique des feuilles d’or des tesselles montre que les compositions des feuilles d’or sont comparables à celles des monnaies jusqu’au VIe siècle. À partir du VIIIe siècle on constate une diversification de l’approvisionnement.
Research Methods and Methodologies Used in Studies on Social Accounting
Authors: Tavares Maria da Conceição da Costa , Dias Alcina Portugal
Published: October 2021

Accounting as a social science considers an objective and subjective reality that must be seen and understood under the institutional context where it is developed. Thus, this chapter discusses the roles and effects of the paradigms in accounting research, in general, and social accounting research, in particular, aiming to know and understand the research lines that better define a theoretical scope of analysis for the social accounting practice. This research tries to better fit the answers to some questions about social accounting. The results argue for the importance of keeping a theoretical paradigm alive in order to foster multidimensional openness and true scholarship in accounting research and application. A multi-disciplinary appreciation with different perspectives will enrich the research in social accounting.

Authors: Pinto-Llorente Ana María
Published: October 2021

The aim of the study is to explore learners' perception of case study method within the context of a Degree in Infant Education. The research is carried out at Salamanca University during the academic year 2017-2018. In order to achieve the goal of the research, a quantitative study is employed. The sample of the research is composed of 77 learners enrolled in the compulsory subject School Organization. To operationalize the variables and collect data researchers use a questionnaire. Analyzing the results, it is highlighted that most learners emphasize the benefits of case study method to be involved in the real context of a classroom setting, and to contribute to the development of different skills such as communication, problem solving, decision-making, organizing and planning, analytical thinking, conflict resolution, negotiation, coordination, cooperation, flexibility, tolerance, and respect. They state that it is a fantastic experience to put into practice the knowledge previously acquired. This research points out how the case study method maximizes the learning experience.
Unconscious Bias Towards African American Women in the Education Workforce
Authors: Harris Deborah Carol Fields
Published: October 2021

The number of African American women who become school principals is low per national and local statistics. An unconscious bias towards African American women may have contributed to these low statistics. The process of applying for a school principal's position has not been consistent for over a century. It seems that for job openings in which the dominant culture is not African American, the likelihood of being the school principal is doubtful. Unveiling and examining these biases may lead to determining how to include more African American women in educational administration. This chapter will describe 10 African American women who encountered unconscious bias as they sought and procured public-school principalship.

Authors: Inthiran Anushia
Published: October 2021

Many health organizations use Facebook as a platform to engage with users. This has resulted in many research studies conducted on this platform. One popular type of research study is to characterize posts and measure user engagement levels . In this study, 100 post on the Mental Health Foundation of New Zealand Facebook page was analyzed this purpose. A mixed method approach was used. Quantitative descriptive statistics was used to analyze levels of engagement whilst qualitative content analysis was used to characterize posts into themes. Preliminary results indicate most posts fit in the awareness theme followed by the campaign theme. High levels of user engagements was observed for posts related to the awareness and others theme. Results of this study makes the suggestion for the implementation of intervention type awareness posts. A recommendation is also to made that the awareness posts promote mental health education and communication. This research study adds new knowledge to the area of posts characterization and user engagement levels on a mental health Facebook page.
Spatio-temporal modelling of tick life-stage count data with spatially varying coefficients
Authors: Lephoto Thabo , Mwambi Henry , Bodhlyera Oliver , Gaff Holly
Published: October 2021

There is a vast amount of geo-referenced data in many fields of study including ecological studies. Geo-referencing is usually by point referencing; that is, latitudes and longitudes or by areal referencing, which includes districts, counties, states, provinces and other administrative units. The availability of large geo-referenced datasets for modelling has necessitated the development and application of spatial statistical methods. However, spatial varying coefficients models exploring the abundance of tick counts remain limited. In this study we used data that was collected and prepared by researchers in the Department of Biological Sciences from the Old Dominion University, Virginia, USA. We modelled tick life-stage counts and abundance variability from 12 sampling locations, with 5 different habitats (numbered 1-5), three habitat types; namely: woods, edges and grass; collected monthly from May 2009 through December 2018. Spatio-temporal Poisson and spatio-temporal negative binomial (NB) count data models were fitted to the data and compared using the deviance information criteria (DIC). The NB model outperformed the Poisson models with all its DIC values being smaller than those of the Poisson model. Results showed that the covariates varied spatially across counties. There was a decreasing time (in years) effect over the study period. However, even though the time effect was decreasing over the study period, space-time interaction effects were seen to be increasing over time in York County.
An interpretation of Cueva de la Huachizca, Santa Clara del Cobre, Michoacan, Mexico
Authors: Campos Cinthia , Punzo-Díaz Jose , Delgado Veronica , Goguitchaichvili Avto , Morales Juan
Published: October 2021

Cueva de la Huachizca is located in the humid forests of the Municipio of Santa Clara del Cobre, Michoacán. During the Postclassic period (1300−1520 ad), Santa Clara del Cobre was a part of the Tarascan Señorio. Ethnographic accounts describe the use of Cueva de la Huachizca as a place of refuge during the Cristero Rebellion (1921−1926). Recent investigations suggest a long history of use including graffiti and inscriptions from the 1800s–1900s and a rock art panel. The panel consists of pecked petroglyphs depicting a man facing an eagle, above a spiral motif. Stylistic analysis of the panel suggests that the rock art was created during pre-Hispanic times, likely by the Postclassic Tarascans. As observed in several regions of Mesoamerica, for the Tarascans, caves were also liminal spaces and had an important role in Postclassic Tarascan cosmology. A ceramic resinera, a pine resin pot, an eagle’s feather, and charcoal were also recovered. The resinera age was estimated by researchers at Archaeomagnetic Services, Geophysics Institute at the National Autonomous University of México-Campus Morelia, Michoacán to between 1921 and 1980. Ethnographic and ethnohistoric accounts describe caves as houses of fertility and rain deities, an idea that while slightly transformed, has survived over 500 years of colonization, and remains in the communities’ social memories. These findings demonstrate the cave’s significance among the descendent communities and Cueva de la Huachizca as an important sacred site.

The paper presents data on the creation of a tungsten target, protected from corrosion under irradiation with a power of up to 100 kW. A protective coating of tantalum with a thickness of 250 μm was deposited on the surface of tungsten plates 66x66 mm, thickness 10; 6; 4; 3 mm. The coating has a solid-phase compound over the entire surface of tungsten and is hermetic. This was achieved by CVD (chemical vapor deposition) tantalum deposition in a vacuum of 2.66•10-2 Pa on a plate surface heated to ~ 1700 K using the thermal dissociation reaction of tantalum pentachloride vapor. Such tungsten plates, equipped with tantalum coatings with desired properties, were used in the Neutron Source installation of the NSC KIPT.

El cálculo de las estructuras de soporte para señalizaciones viales se realiza mediante la norma AASHTO con la cual se realiza fundamentalmente el chequeo a Fatiga, pero con ella no se llegan a conocer las tensiones von Mises, las tensiones tangenciales ni los desplazamientos en cualquier punto de la estructura. En el presente trabajo se determinan las cargas actuantes, así como sus combinaciones más críticas para el análisis. Se realiza el cálculo analítico a través de los métodos y las normas establecidas para ello y se confecciona un modelo de elementos finitos cuya simulación numérica complementa los resultados obtenidos por las normas.

RESUMEN

En la actual sociedad de la información y del conocimiento se observa cómo la proliferación y el auge de los dispositivos móviles, hacen surgir nuevos modelos de aprendizaje que reformulan las metodologías didácticas, organizativas, y de formación de los currículos, para innovar en educación (Moreno Martínez, Leiva Olivencia, & Matas Terrón, 2016). Los estudios que identifican las tecnologías emergentes que podrían impactar en el aprendizaje, la enseñanza y la investigación, prevén el aumento del uso y la incorporación de dispositivos y aplicaciones móviles en las aulas (Reig, 2013; Reig & Vílchez, 2013). Destaca el aprendizaje basado en juegos o gamificación, que permite desarrollar procesos de enseñanza-aprendizaje que facilitan la cohesión, la integración y la motivación, potenciando la creatividad del alumnado. Crear juegos entretenidos motivará al alumnado para que participe de forma activa en clase, fomentará una sana competencia entre los jugadores, y hará del aprendizaje algo más divertido (Aleksić-Maslać, Rašić, & Vranešić, 2018). Utilizando Kahoot en dispositivos móviles como soporte para las clases de Dirección de Operaciones del Grado en Administración y Dirección de Empresas de la Universidad de Cádiz, se consiguió motivar al alumnado y, aun existiendo otros factores determinantes, mejorar sus resultados de evaluación.

 

ABSTRACT

In today's information and knowledge society, the proliferation and rise of mobile devices has led to the emergence of new learning models that reformulate didactic, organizational and curricular training methodologies in order to innovate in education (Moreno Martínez, Leiva Olivencia, & Matas Terrón, 2016). Studies that identify emerging technologies that could impact learning, teaching and research, foresee increased use and incorporation of mobile devices and applications in classrooms (Reig, 2013; Reig & Vílchez, 2013). Learning based on games or gamification stands out, which allows the development of teaching-learning processes that facilitate cohesion, integration and motivation, boosting students' creativity. Creating entertaining games will motivate students to participate actively in class, encourage healthy competition between players, and make learning more fun (Aleksić-Maslać, Rašić, & Vranešić, 2018). Using Kahootin mobile devices as support for the classes of Operations Management of the Degree in Business Administration and Management of the University of Cadiz, it was possible to motivate the students and, although there are other determining factors, to improve their evaluation results.

Published: October 2021

A necessidade de redução do tempo e dos custos de geração de um projeto faz com que a indústria utilize métodos de simulação numérica para o desenvolvimento de produtos. O objetivo deste trabalho é avaliar quais os modelos e métodos de solução são mais adequados e eficientes na simulação da conformação de chapas pelo MEF, através de modificações dos parâmetros de simulação, tais como: técnica de integração no tempo, velocidade de análise e refino de malha. Para tanto, é simulado o ensaio de estiramento de chapas finas proposto pela Universidade do Estado de Ohio e o embutimento de uma lata de atum. Nas simulações é utilizado o código ABAQUS. Observa-se, que o método implícito dinâmico possuir uma melhor precisão nos resultados simulados, quando comparados com os resultados experimentais e apresenta um elevado custo computacional. Em virtude de tal fato, o método explícito dinâmico apresenta uma melhor relação custo/benefício. Conclui-se que avelocidade imposta ao modelo, apresenta uma grande influência na acurácia dos resultados. Observa-se que mesmo para níveis de velocidade muito baixos a relação energia cinética/energia de deformação é superior a 5%. Outro aspecto que apresenta elevadainfluência na precisão dos resultados é o refino da malha da chapa.

Devido ao grande volume de dados que são gerados pelas Empresas que utilizam Sistemas de Informação, é fundamental o papel do Banco de Dados (BD). Geralmente os dados precisam ser acessados a todo instante, logo, a disponibilidade dos resultados nem sempre são satisfatórias. Nesse contexto, entra a questão do desempenho ao se obter informações de um BD e como otimizá-las. Muitos problemas de performance não estão relacionados a infraestrutura, sistemas operacionais ou mesmo ao hardware. Pode-se encontrar problemas de perda de performance dentro do próprio BD, sendo a consulta a principal causadora desses problemas. Ajustar e otimizar uma consulta e o próprio BD tornam-se fatores importantes, podendo-se ter um ganho de performance aceitável, visto que cada consulta é tratada de forma diferente, dependendo do Sistema Gerenciador de Banco de Dados (SGBD). Este artigo avalia como melhorar o desempenho de consultas Transact-Structured Query Language (T-SQL) em um ambiente Microsoft SQL Server 2005, sugerindo possíveis alterações que possam levar a um ganho de performance considerável.

Authors: Vasconcelos Daniela V. , Gomes Anderson
Published: October 2021

Buscando pesquisar processos alternativos para o tratamento de efluentes, este trabalho estudou a aplicação de um processo oxidativo avan- çado, POA, (H2 O2 /UV), para o tratamento de um efluente originado de lavagens de carros para fins de reúso com o objetivo de reduzir o valor inicial de cor aparente, turbidez, condutividade, demanda química de oxigênio (DQO), óleos e graxas, amônia, sólidos suspensos, dissolvidos, surfactantes, verificando se a qualidade final da água para que ela possa ser reutilizada nas lavagens. Soluções do efluente foram submetidas ao tratamento proposto, utilizando-se um reator comercial com lâmpada de luz ultravioleta com volume útil de 350mL. Foram estudadas diferentes concentrações de peróxido de hidrogênio em diferentes pH’s. Pelos resultados obtidos no presente estudo, observou-se que o POA H2 O2 /UV é um processo de tratamento que pode ser aplicado no tratamento do efluente das lavagens de carros em postos de combustíveis.
Avaliação da Adequação do Almoço de uma Unidade de Alimentação e Nutrição (UAN) ao Programa de Alimentação do Trabalhador (PAT) Evaluation of Lunch Adequation in a Feeding and Nutrition Unit (FNU) to the Worker Feeding Program (WFP)
Authors: Mattos Priscila Fonte
Published: October 2021

Em uma Unidade de Alimentação e Nutrição, a alimentação adequada é fundamental para a promoção da saúde do trabalhador e para o bom desempenho de suas funções. O Programa de Alimentação do Trabalhador – PAT foi criado para melhorar a qualidade de vida dos trabalhadores, ou seja, melhorar as condições nutricionais através da alimentação adequada. Foi publicada a Portaria n° 66, de 25 de agosto de 2006, que alterou os parâmetros nutricionais do PAT. Segundo essa portaria, as refeições principais como almoço, jantar e ceia devem conter de 600 a 800 kcal, podendo haver um acréscimo de 20% (400 kcal) em relação ao Valor Energético Total de 2000 kcal. Essas mudanças nos parâmetros do PAT foram resultados de  varios estudos que demonstraram que o programa não cumpria adequadamente seus objetivos de promover a saúde do trabalhador e a educação nutricional, sendo encontrados altos percentuais de aumento de peso e doenças crônicas não transmissíveis como a hipertensão em trabalhadores cobertos pelo PAT. O presente estudo avaliou a cardápio de cinco dias de uma UAN com o objetivo de verificar se as calorias diárias, assim como macronutrientes e NDPcal%, estavam de acordo com o PAT.  Concluiu-se que  as calorias diárias e macronutrientes pesquisados no cardápio realizado da UAN estavam em desacordo com os Parâmetros do PAT, estando de acordo somente o percentual protéico de um dia da semana e o NDPcal% de todos os dias analisados. Isso mostra que o cardápio do almoço da UAN ao invés de promover a qualidade de vida do trabalhador, pode piorar, fazendo com que há um aumento de peso dos trabalhadores e também aumento do risco de doenças crônicas não transmissíveis.

Notas preliminares de uma crítica feminista aos programas de transferência direta de renda: o caso do Bolsa Família no Brasil
Authors: Gomes Simone da Silva Ribeiro
Published: October 2021

Nos últimos anos, os programas de “luta contra a pobreza” e transferência direta de renda estão presentes na maioria dos países latino-americanos. A partir do primeiro ano de governo do presidente Lula (2003), o Brasil enfatiza essa forma de política social, ao unificar diferentes modelos de transferência do governo anterior (1995-2002) em um só programa: o Bolsa Família. O presente artigo busca expor a crítica da regulação da pobreza e o impacto das condicionalidades referentes a esta lógica de intervenção na reprodução social de um grupo específico. A relação entre o Estado e as mulheres – responsáveis únicas pelo sustento financeiro de suas casas e, majoritariamente, as maiores beneficiárias destes programas - é caracterizada por atravessamentos em termos de classe social, gênero e raça. Ao apresentar a perspectiva feminista, este artigo procura abrir uma série de questões ao analisar como as condicionalidades impostas pelo Programa Bolsa Família tendem a naturalizar o papel reprodutivo das mulheres na sociedade brasileira, limitando seu espaço de agenciamento e emancipação.

O presente estudo apresenta como objetivo correlacionar a realidade pedagógica da Educação Física Escolar com o desenvolvimento de modalidades esportivas individuais, aqui especificamente se tratando do Atletismo, da Ginástica Artística, do Tênis e das Lutas. Foram realizadas reflexões em dimensões específicas destas modalidades, como os conteúdos a serem trabalhados, o rendimento em competições, as possibilidades de inserção dos esportes individuais no cotidiano das aulas de Educação Física e a relação entre a prática sistematizada de modalidades esportivas com a vida acadêmica dos alunos. Para a realização do estudo, empregou-se a pesquisa bibliográfica como metodologia, e utilizou-se o método descritivo da bibliografia com o objetivo de expor as opiniões de autores voltados para a pesquisa relacionada a esportes individuais e o cotidiano das aulas de Educação Física em ambiente escolar. O esporte de maneira geral constitui-se em um valioso conteúdo das aulas de Educação Física em função das inúmeras possibilidades de ações associadas ao mesmo. Entretanto, torna-se necessária a percepção de que ele deve ser apresentado aos alunos não apenas como uma gama de movimentos repetitivos e condicionados, mas como um caminho para o desenvolvimento social, cognitivo, motor e afetivo dos seus praticantes, respeitando sempre a faixa etária em que eles se encontram.

The purpose of this study was to examine the effect of adding different levels of black cumin seed (BCS) to the compound feed on performance, serum criteria, and reproductive hormones in male Japanese quails (Coturnix coturnix Japonica). 80 male Japanese quails (Coturnix coturnix Japonica) at the age of 21 days were used in the study. The trial was carried out with 5 repetitions in 4 treatment groups (20 subgroups with 4 animals in each cage) and completed in 3 weeks. The treatment groups were as follows: Group A (the control group fed with basal feed, 0%); Group B (the group fed with basal feed + 0,5% black cumin seed); Group C (the group fed with basal feed + 1,0 % black cumin seed); and Group D (the group fed with basal feed + 2,0% black cumin seed). In the study, it was found that the addition of black cumin seed to the rations of male quails had no significant effect on their performance, testicular characteristics, serum parameters, and reproductive hormones. However, it was also found that the addition of 0,5% BCS caused an increase in the ratio of testicular weight to live weight, and the serum FSH levels tended to decrease with the addition of BCS; so there is a need for more studies on this subject.

Christia vespertilionis (L. f.) Bakh. f. has been widely known in treating various contagious diseases. This plant is popular among
researchers and locals to have anti-inflammatory, and anti-cancer properties. There are two types of C. vespertilionis which is green
and red type. The green C. vespertilionis was extensively studied by many researchers and known by the public as a cure to the cancer.
This study was carried out to identify major phytochemicals and optimise extraction method of green C. vespertilionis leaves in
different extraction techniques (maceration and Soxhlet extraction) and solvents (methanol and ethanol) through GC-MS analysis.
The green C. vespertilionis leaves extract was tested using Gas Chromatography Mass Spectrophotometer (GC-MS). The components were identified by comparing National Institute of Standards and Technology (NIST). Based on four samples which are green C. vespertilionis leaves using maceration of methanol (GMM), maceration of ethanol (GME), Soxhlet of methanol (GSM) and Soxhlet of ethanol (GSE), seventy phytochemical compounds were identified. Thirteen major phytochemical compounds (> 4 % of peak area) are acetic acid, butyl ester; 1-Butanol, 3-methyl-, acetate; 1,3-Diisobutyrin, trimethylsilyl; .alpha.-d-Mannofuranoside, methyl; 1-
Tetradecene; 1-Hexadecene; 1-Octadecene; Hexanoic acid, 3-oxo-, ethyl ester; 4-O-Methylmannose; n-Hexadecanoic acid; Phytol;
9,12,15-Octadecatrienoic acid, (Z,Z,Z)- and Squalene. Only ten out of thirteen compounds were reported to have biological activities.
Among those samples, GMM and GSM were the most effective using correlation coefficient analysis between peak area (%) versus
real time (min) with significant difference at P < 0.001.

Diabetes mellitus is a disease that is increasing globally and is a group of metabolic disorder, characterized by polyuria, polyphagia
and polydypsia. By maintaining glycemic index levels in individuals diet aids in prevention of diabetes. Rice, millets and legumes are
considered to be one of the staple food and play a vital role in human diet. In our study the glycemic index of varieties of rice, millets
and legumes were determined in-vitro. Consumption of foods with high glycemic index is hypothesized to contribute to insulin
resistance, which is associated with increased risk of diabetes mellitus, obesity and cardiovascular disease. It was seen that the
legumes possess low glycemic index with comparison to rice and millets. Hence, it can be concluded that legumes are particularly
good for preventing and managing diabetes.

Type II diabetes mellitus is a common global hormonal disorder. Inhibition of dipeptidyl peptidase – 4 by dipeptidyl peptidase – 4
inhibitors enhances hormonal activity of incretins, like GLP – 1, GIP, GRP, stimulates insulin release and reduces glucagon secretion,
finally producing anti-hyperglycaemic activity in diabetic patients. A clinical pharmacological study of the prevalent prescription
patterns of metformin, sitagliptin and gemigliptin among the early moderate grade new type II diabetes mellitus patients in global
multi-centre tertiary care hospitals. 100 new early moderate grade type II diabetes mellitus patients, were prescribed oral metformin
500 mg once daily, sitagliptin 25 mg once daily or gemigliptin 25 mg once daily for 3 months, in monotherapy, or in combination
therapy, or in a mixed regimen of monotherapy and combination therapy. The safety and efficacy assessments, with blood sugar and
HbA1c levels and urine examination, at subsequent intervals and follow-up, were recorded and analysed. The number of prescriptions
for each drug was recorded, and the respective prescription rates were statistically analysed in percentages. Metformin was most
commonly prescribed (80 prescriptions, 80%), followed by sitagliptin (16 prescriptions, 16%), and gemigliptin (4 prescriptions, 4%). Prescription frequency of metformin was followed by sitagliptin and then by gemigliptin.
