Impact of Covid-19 on Domestic Violence in South Asia
No full textDomestic violence, rooted in patriarchy and conservatism, significantly increased during the COVID-19 pandemic, presenting a challenge to gender justice. This study examines the pandemic's impact on domestic violence in Pakistan, Bangladesh, India, Nepal, and Sri Lanka, using an exploratory mixed-methods approach. In-depth interviews (IDIs) and key informant interviews (KIIs) with practitioners and experts, alongside a web-based survey with field-level practitioners and community members, revealed that domestic violence surged during the pandemic. Factors such as mobility restrictions, loss of livelihoods, and prolonged presence of men at home exacerbated violence against women and young girls. Additionally, increased household chores, school closures, and the absence of recreational activities led to heightened aggression. The findings highlight that domestic violence was a widespread issue across social classes in South Asia, reflecting the pandemic's deep impact on socio-economic and familial dynamics, with women and children bearing the brunt of this crisis
Socio-Cultural Determinants of Child Marriages and Teenage Pregnancies among Adolescent Girls and Young Women: A Case Study of District Sanghar and Karachi
No full textChild marriages and early age
pregnancy are an alarming issue
among adolescent girls and young females in South
Asian region. This research was carried out to
understand the knowledge, attitude, and practices
towards child marriages and early age pregnancies.
For this purpose an exploratory research design was
employed and data was gathered through using
qualitative and quantitative research techniques. The
research found that the respondents were lacking
authentic knowledge about sexual and reproductive
health rights. Most of the respondents were having
access to public and private health service providers
and this channel can be a source for the quality
information about sexual and reproduce health and
rights. An integrated approach through combing all
the channels and stakeholders of the society can be
vital for the desired social change to counter child
marriages and early age pregnancies
Control data separation and its implications on backhaul networks
No full textFuture cellular systems need to cope with a huge amount of data and diverse service requirements in a flexible, sustainable, green and efficient way with minimal signalling overhead. This calls for network densification, a short length wireless link, efficient and proactive control signalling and the ability to switch off the power consuming devices when they are not in use. In this direction, the conventional alwayson service and worst-case design approach has been identified as the main source of inefficiency, and a paradigm shift towards adaptive and on-demand systems is seen as a promising solution. However, the conventional radio access network (RAN) architecture limits the achievable gains due to the tight coupling between network and data access points, which in turn imposes strict coverage and signalling requirements irrespective of the spatio-temporal service demand, channel conditions or mobility profiles
Resilience and cleaner production in industry 4.0: role of supply chain mapping and visibility
No full textIndustry 4.0 makes the business processes more autonomous, automated, and intelligent. Supply chain mapping can be a steppingstone to adopt the developments of Industry 4.0. Despite its profound significance in Industry 4.0 driven supply chain management, it has been hardly discussed in the research literature. Against this backdrop, the objective of this study is to test the impact of supply chain mapping on a firm's supply chain visibility and resilience. Data were collected from 154 Electrical & Electronics sector Malaysian firms through a close-ended questionnaire. The study employed structural equation modeling to analyze the hypothesized relationships. A significant momentous effect of supply chain mapping was found on the supply chain visibility and supply chain resilience. Further, the study also found a significant mediating role of supply chain visibility in the association between SC mapping and supply chain resilience. The findings of the study strongly suggest firms adopt a supply chain mapping strategy to improve supply chain visibility and supply chain resilience. Findings also suggest maintaining closer ties with key suppliers in order to increase SC visibility
Cognizance of Color Blindness in University-Girls-Hostel Residents
No full textThe main purpose of the study was awareness about color blindness, its causes and impact on health in university-girls-hostel residents. Eighty students joined in this study. All the students of Bahauddin Zakariya University Multan Khadija hall girl’s hostel were involved in that study in which they were asked about color blindness it provides answers like is color blindness a viral infection or a bacterial disease, metabolic disease. Any one of you your family and friends have ever suffered from this disease? How can we treat it with the use of medicines or surgery? It is shifted genetically or by blood transfusion contact. Which they were asked about color blindness disease type and it’s diagnose and how it can be controlled either by surgery or medicines or no need of its treatment and how it spreads and family friends history of this disease. A survey was done by the awareness about color blindness its reasons and effect on health. A survey was done by the awareness about color blindness its reasons and effect on health. The statistical analysis was done by using MS word. Above study showed that majority of students said that AIDS is a bacterial disease rather than fungal disease. 67.5% of students claimed it as a bacterial disease but 36.25% said that it is not a genetically transferred disease. 53.75% of students had this disease
Docking Study of Altered Nelfinavir & Indinavir with Protease of Human Immunodeficiency Virus
No full textNelfinavir and Indinavir are protease inhibitors that function against HIV-1 (HIV-1). Protease inhibitors act by preventing HIV's protease enzyme from functioning. Infectious HIV-1 protease enzyme is proteolytic enzyme in nature that transforms virus causing polyprotein precursors into particular functional proteins. Nelfinavir and Indinavir bind to the protease's active site and prevent it from working. This inhibitor prevents the breaking of virus causing polyproteins, preventing the growth of immature and the non-infectious virus causing particles. However, protease inhibitors are always utilized with at least two further drugs which are anti-HIV drugs. Using the pubchem database from NCBI, we used docking techniques to find the structures of Indinavir and nelfinavir. Then used ds4.1 to modify it then open in auto dock or pay mole to see their attachment after docking with protein

The college of medicine at King Khalid University has acknowledged this trend and embarked on reviewing its curriculum.
Objectives: To evaluate the undergraduate medical curriculum using SPICES model of curriculum evaluation as a tool with the view to plan and shape future curriculum reforms at the college of medicine, King Khalid University.
Methodology: A questionnaire-based survey was conducted eliciting the responses of faculty members and the departmental chairmen regarding the practice of student centred, integrated and non-traditional teaching methods as well as a separate questionnaire for the quality of problem-based learning in practice. The compiled responses from all the respective departments were statistically analysed subsequently.
Results: An average of 43.5% of student-centred learning (SCL), 41% of Integrated teaching (IT) and 19% of Non-traditional teaching (NTT) is being employed in different departments of the college of medicine.
Conclusion: The results suggest that the college of medicine is currently carrying out traditional teacher centred, discipline based and information-oriented teaching along with small chunks of student centred, integrated and problem-based teaching methods. Although the problem-based learning is proportionately very small in practice but in general, its quality is better in the clinical departments as compared to the basic sciences departments.
