Scholastic Performance Among Senior High School Students In Distance Learning During The Covid-19 Pandemic
Get PDFThis study essentially made use of a descriptive-correlation design where it attempted to measure the Scholastic performance of Senior High School students in distance learning through a virtual set-up. A descriptive survey was used to describe the profile of the respondents in terms of age, sex, birth order of siblings in the family, parents' highest educational attainment, parents’ occupation, family monthly income, and gadget/s used in online learning. A test of correlation was conducted to analyze the Home Environment, Parental Educational background, Socioeconomic status, Teacher factor, Technology resources, and Learning. The name of the program is “Future Ready, Future Smart,” commonly known as the FRFS Program, wherein the students learn by using the Study Guides (modules) and Video Lectures provided to them by their learning facilitator. In order to ensure the bridging of the learning gaps, Good Samaritan Colleges-Senior High School also requires the students to attend their Virtual Classes. Considering the results, fifty-nine percent (59%) of the respondents belong to the eighteen (18) to nineteen (19) age bracket. This age group represents those students in Senior High School or those in Grades 11 and 12, which belongs to Generation Z. Sixty-four percent (64%) of the respondents represented Female students. Females are known to mature faster than males as they undergo puberty and finish it earlier. Also, they usually spend more time doing homework than boys. Forty-six (46%) students are firstborns. Firstborns are expected to lead and take care of their siblings so they are usually responsible and reliable. Fifty-seven percent (57%) of the parents of the respondents are college graduates. By reaching a higher level of education, the parents can guide their children in their studies and be examples/role models in attaining their goals in life. Fifty-six percent (56%) of the parents of the respondents have a various occupation, such as government and private company employees, farmers, policemen, welders, lawyers, and drivers. This shows that their parents came from all walks of life. A family of thirty-eight percent (38%) of the respondents earn twenty-five thousand pesos (P25,000) and above per month. These families may be classified as middle-income class families. Forty-nine percent (49%) of the respondents use laptops in their online classes; Laptop, although generally more expensive, is more convenient to use in online classes. Being able to provide a better gadget to be used in their children’s online studies may be attributed to the parents having an occupation.It just shows that there is a significant relationship between the Parents’ Highest Educational Attainment and the Academic Performance of the respondents for School Year 2020-2021 only; and between the Learning Style and the Academic Performance of the respondents for School Year 2019-2020 only. The rest has no significant relationship with the Academic Performance of the respondents for School Year 2019-2020, School Year 2020-2021, and School Year 2021-2022
Behaviour Of Anopheles Gambiae S.L. To Different Concentrations Of Insecticide, Kingasani District, Kimbanseke Commune, City Of Kinshasa, Dr Congo
Get PDFThe results of these investigations reveal that the waste management and environmental sanitation system in place in the Commune of Kimbanseke and specifically in the Quartier Kingasani is inefficient and consequently has health and environmental weaknesses, which would mean it is not environmentally friendly.This is due to a number of variables, including poor use of LLINs and insecticides, insalubrity, the absence of a genuine environmental management policy, mesological education, entomological surveillance and ongoing public awareness-raising.The study of the resistance of Anopheles vectors of malaria subjected to different concentrations of insecticides in the Quartier de Kingasani, Commune de Kimbanseke, city of Kinshasa in DR Congo consisted firstly of a larval prospection and localization of larval sites, obtaining adults after rearing in the insectarium, which allowed the realization of sensitivity tests in order to observe the behavior of Anopheles facing different concentrations of insecticides and to highlight the rate of resistance.Among the five insecticides exposed to Anopheles, these mosquitoes were highly sensitive to three insecticides (Alpha cypermethrin 0.5%, bendiocarb 0.1% and deltamethrin 0.05%), but showed resistance to two insecticides (Permethrin 0.75% and pirimiphos methyl 0.1%).Thus, it is clear that the misuse of LLINs and a variety of insecticides from unknown sources, sold to markets could be the main cause of the increased resistance of Culicidae and sometimes other arthropods of medical interest in the Kingasani micro ecosystem
Etude Théorique De L’Influence De L’Induction Magnétique Sur La Résistivité Electrique D’un Conducteur
Get PDFRésumé— Cet article est dédié à l’étude théorique de l’influence de l’induction magnétique sur la résistivité électrique d’un matériau. Le calcul étant fait en supposant que la température du milieu magnétisé est dans une gamme de 273 à 300K, une gamme où l’effet de la température est supposée négligeable sur l’évolution de la résistivité [5,6,7]. Le résultat de notre calcul théorique montre que l’omniprésence de soumission d’une induction magnétique et d’un champ électrique à un matériau modifie légèrement sa résistivité électrique. Ainsi la résistivité obtenue est baptisée par résistivité électromagnétique ou bien par magnéto – résistivité
