Media Interaktif Virtual Reality Biota Laut Indonesia Sebagai Media Pembelajaran Untuk Usia 11-13 Tahun

Indonesia merupakan negara kepulauan yang memiliki wilayah lautan yang sangat luas serta kekayaan keindahan bawah laut. Keindahan tersebut karena adanya faktor ekosistem biota laut yang masih terjaga. Meskipun kaya akan keindahan lautnya, Indonesia juga mempunyai banyak ancaman yang bisa merusak ekosistem biota laut sehingga menimbulkan ancaman kepunahan bagi biota laut di Indonesia. Hal tersebut dikarenakan rendahnya pengetahuan dan minat masyarakat terhadap biota laut. Salah satu upaya untuk meningkatkan pemahaman dan minat terhadap biota laut adalah dengan memberikan edukasi sejak dini. Anak-anak sebagai generasi penerus bangsa merupakan agen penting dalam melestarikan biota laut dan ekosistemnya. Mengenalkan biota laut kepada anak-anak dapat dilakukan dengan memanfaatkan teknologi, salah satunya Virtual Reality (VR). Dengan adanya teknologi Virtual Reality mampu memberikan informasi secara nyata dan bisa berinteraksi langsung dengan lingkungan laut. Penelitian ini menggunakan metode penelitian kualitatif yang membahas bagaimana merancang aplikasi Virtual Reality yang sesuai untuk anak umur 11-13 tahun yang dapat mensimulasikan bawah laut sebagai aplikasi edukasi. Aplikasi dengan teknologi virtual reality ini dapat dijadikan sebagai media alternatif dalam pembelajaran tentang biota laut untuk anak-anak dan sebagai upaya pelestarian biota laut di Indonesia. Kata kunci: Aplikasi edukasi, Virtual Reality, Biota laut

Les protéines de choc thermique (heat shock proteins). I : Classification, structure, fonctions et implications dans les processus pathologiques

All living systems have evolved mechanisms to maintain homeostasis in the face of rapid environmental changes. When exposed to elevated temperatures, most of the cells activate the synthesis of a specific group of proteins called Heat Shock Proteins (Hsps). This heat shock response, under control of specific transcription factors, the Heat Shock factors (HSF), is an evolutionarily conserved mechanism, from bacteria to humans. Heat Shock Proteins are classified into families according to their molecular weight (Hsp 25, 40, 70, 90, 105). They play the role of molecular chaperones by binding and protecting other molecules (proteins, RNAs). The function of Hsp is to prevent accumulation of non-native proteins either by assisting proper folding of polypeptides or by driving them to proteosome pathway for degradation. Hsps are involved in various pathological processes that are accompanied by protein alterations such as chronic or degenerative diseases. This review describes structural and functional characteristics of the six main Hsps classes. It also focuses on their respective role in highly studied pathologies. The diversity of Hsps implications in these diseases explains that they became recently a strategic target in development of new therapeutic strategies.Tout organisme est doté de mécanismes lui permettant de résister à de brusques changements de son environnement. Exposées à une température anormalement élevée, la plupart des cellules activent l’expression d’une classe particulière de protéines appelées les protéines de choc thermique (Heat Shock Proteins, Hsps). Cette réponse cellulaire au choc thermique placée sous le contrôle de facteurs de trans-cription spécifiques, les facteurs de choc thermique (Heat shock factor, HSF) est un mécanisme conservé au travers de l’évolution depuis les bactéries jusqu’à l’homme. Les protéines de choc thermique qui sont divisées en familles désignées par leur masse moléculaire (Hsp25, 40, 70, 90, 105) font partie des molé-cules chaperons qui s’associent à d’autres molécules (protéines, ARNs) et en protègent la destinée. Le rôle des Hsp est d’empêcher l’accumulation de protéines anormales en aidant à conformer correctement les polypeptides ou en les dirigeant vers le protéosome qui les détruit. En tant que chaperons, les Hsp sont impliquées dans de nombreux processus pathologiques qui s’accompagnent d’altérations des protéines comme les maladies chroniques et dégénératives. Cette revue décrit les spécificités structurelles et fonc-tionnelles des six familles principales d'Hsp ainsi que leur intervention à différents niveaux dans les patho-logies les mieux étudiées. La multiplicité de l'implication des Hsp dans ces phénomènes pathologiques les désigne comme cibles privilégiées dans le développement de nouvelles stratégies thérapeutiques

Dilemmas in doing insider research in professional education

This article explores the dilemmas I encountered when researching social work education in England as an insider researcher who was simultaneously employed as an educator in the host institution. This was an ethnographic project deploying multiple methods and generating rich case study material which informed the student textbook Becoming a Social Worker the four-year period of the project. First, ethical dilemmas emerged around informed consent and confidentiality when conducting surveys of students and reading their portfolios. Second, professional dilemmas stemmed from the ways in which my roles as a researcher, academic tutor, social worker and former practice educator converged and collided. Third, political dilemmas pertained to the potential for the project to crystallize and convey conflicts among stakeholders in the university and community. Since the majority of research in social work education is conducted by insiders, we have a vital interest in making sense of such complexity
