The objective of research was to determine the concentration of honey in sperm dilution for improving hatching rate of egg and survival of nile tilapia larvae (Oreochromis niloticus).The number of fish used was five pairs broodstock. Dilution substance was NaCl and honey. Observations were conducted on spermatozoa motility, fertility and egg hatching rate. Experimental design used was complete randomized design. Sperm dilution substance was prepare by disolving honey (0 mL; 0,60 mL; 0,65 mL dan 0,70 mL) in 100 mL; 99,40 mL; 99,35 mL and 99,30 mL NaCl respectively. Each dilution was homogenized using aerator for 15 minutes. Fertilization was done 12 hours after ovulation. Egg hatching rate was observed after ovulation. Research results showed the use of honey had significant effet on egg hatching rate, but not on larval survival. Treatment D (0,70 mL honey in 99,30 mL NaCl) had the highest hatching rate (77.33%). Dilution ratio 1:60 was the best indicated by spermatozoa motility 96.66%, fertility 71.65, hatching rate 70% and larval survival 81.67% Keywords : honey, egg hatching rate, larval survival, Oroechromnis niloticus

Absolute Growth, hemolymp osmolality, oxygen consumption, and basal energy of Litopenaeus vannamei postlarvae were investigated. After post larval stage, PL-20, the postlarvae were acclimatized from sea water (25 ppt) to low salinity water (2 ppt) over 96 h. Treatments consisted of different concentration of K+added to distilled water. Four different levels of K+ (0, 30, 60, and 90 ppm) were utilized. Ten shrimp were placed in triplicate 40-L glasses aquarium. Results from the 42-day K+ growth trial indicated significant differences (P< 0.05) in absolute growth, hemolymp osmolality, oxygen comsumption, and basal energy. The values in treatment A was significantly higher than than those under the other four treatments. The results suggest treatment C were the optimum K+ level for culture vaname postlarvae in low salinity water. Keywords : Litopenaeus vannamei, oxygen comsumption, hemolymp

Métodos: Estudio de casos y controles en 180 personas con síndrome metabólico (casos) y 180 que no presentaban síndrome metabólico (controles). Se realizó una encuesta en la que se le preguntaba a las personas su edad, género, tipo de dieta, antecedentes patológicos familiares, síndrome metabólico y colecistectomía. Resultados: De los 360 sujetos, respecto a colecistectomía, se encontró que 162 (51.3%) no fueron colecistectomizados y no presentaban síndrome metabólico; 154 (48.7%) colecistectomizados sí presentaron síndrome metabólico, no se encontró una relación significativa, pero sí se le puede atribuir calidad de riesgo para hacer síndrome; sin embargo, la litiasis biliar sí se constituye en un factor de riesgo. El Género masculino fue el que presentó mayor número de casos de síndrome metabólico, estos fueron 111 (52.1%), por otro lado, fueron los mayores de 35 años 139 (47.1%) los que tenían síndrome metabólico. Al considerar la dieta se encuentra una relación significativa (p= 0), pero en función del nivel de consumo de grasas.

Understanding social and cultural aspects of teachers’ digital competencies
Authors: Engen Bård Ketil 
Published: July 2019

Many European governments, including Norway, have ambitious educational policies regarding digitalisation. Many businesses and policymakers pay great attention to the use of digital technologies in education in order to meet the future demands for a competent and qualified workforce. Among researchers and policymakers, there is a general consensus that the professional teacher is a key figure for the successful implementation of digital technologies in schools. Many expectations have been placed upon professional teachers regarding the implementation and use of digital technologies. The professional teacher is, to a certain degree, supposed to independently decide how digital technologies should be used in the classroom. This paper discusses what the concept of a ‘professional digitally competent teacher’ may mean in the context of schools. It also argues the need for a greater understanding of professional digital competence, one which takes into consideration various social and cultural aspects with regard to technology, schools and the teaching profession. In unpacking the social and cultural conditions for implementing technology in a professional teaching context, I will draw on concepts from the constructivist understanding of technology, namely, the ‘domestication of technology’.Muchos gobiernos europeos, incluido el de Noruega, tienen políticas educativas ambiciosas en materia de digitalización. Muchas empresas y responsables políticos prestan gran atención al uso de las tecnologías digitales en la educación para satisfacer la futura demanda de una mano de obra competente y cualificada. Entre los investigadores y los legisladores, existe un consenso general al considerar a los docentes profesionales como una figura clave para la aplicación con éxito de las TIC en la escuela, en lo referente a su implementación y su uso, y se han depositado muchas expectativas en ellos. Se supone que el docente profesional debe, hasta cierto punto, decidir de manera autónoma cómo se han de utilizar estas tecnologías digitales en el aula. Este artículo analiza lo que puede significar el concepto de «docente profesional digitalmente competente» en el contexto de la escuela. También argumenta sobre la necesidad de una mejor interpretación de la competencia digital profesional, que tenga en cuenta diversos aspectos sociales y culturales en relación con la tecnología, las escuelas y la profesión docente. Al analizar las condiciones sociales y culturales para implementar la tecnología en un contexto de enseñanza profesional, nos basaremos en el enfoque constructivista de la tecnología, en concreto, la «domesticación de la tecnología».
Demande d’asile des femmes étrangères : la femme est-elle l’égal des hommes ?
Authors: Mestre Claire 
Published: July 2019

Les consultations transculturelles accueillent de plus en plus de femmes fuyant les multiples violences dont elles ont été les victimes dans leur pays : elles subissent notamment des violences sexuelles accumulées dans le cadre de leur vie familiale, ou bien comme représailles de la part d’agents d’Etats dictatoriaux. L’approche psychothérapeutique permet de leur redonner la parole afin qu’elles puissent se reconstruire. Cependant, ces violences sont mal reconnues par la convention de Genève. Le concept de Françoise Héritier : « la valence différentielle des sexes » permet de comprendre comment les violences faites aux femmes est une question profondément politique. Le concept de « butoir de la pensée » permet d’enclencher la réflexion du comment cette différence homme/femme est brandie et utilisée. Néanmoins, malgré les luttes féministes permettant d’améliorer la protection internationale qui devrait être universelle, il n’en demeure pas moins que des inégalités demeurent dans l’appréhension de l’injustice faite aux femmes devant les violences sexuelles ; l’incompréhension perdure face à la lutte contre l’oppression que constitue l’acte de migrer.
