Abstract:

Occupational Health and Safety (OHS) is a major concern in vital sectors such as the energy sector, especially in countries where law enforcement and safety practices are still developing. This study aims to evaluate the effectiveness of the Occupational Health and Safety Management System (OHSMS) implemented at the General Electricity Company of Libya (GECOL), in light of international standards and global best practices. The research adopted a quantitative and qualitative analytical methodology by analyzing secondary data related to injuries and accidents during the period (2012-2014), in addition to analyzing a field questionnaire that included a sample of workers. The results showed a significant weakness in the application of occupational health and safety management systems, as the percentage of injuries resulting from safety instruction violations reached 36% in 2012, 20% in 2013, and 27% in 2014. The study also revealed the absence of effective supervision, lack of training, and insufficient personal protective equipment. The study concludes with the necessity of adopting an Integrated Occupational Health and Safety Strategy that includes planning, implementation, review, and continuous improvement, emphasizing the importance of training, awareness, and the presence of effective supervisory systems such as ISO 45001. It is important for the company to implement a specific occupational health and safety system, which may be designed by the company or based on international systems.

Abstract

In recent years, we have observed a widespread deficiency in essential nutrients, most notably vitamin D, B12, and calcium, across all age groups. This has led to an increase in chronic diseases and mortality rates among adults. Consequently, we have investigated the causes of these deficiencies and sought to develop preventative, therapeutic, and awareness-raising strategies to mitigate this phenomenon and reduce the prevalence of these nutrient deficiencies among adults. The results showed that vitamin D deficiency was the most common (~58.1%) in both sexes, specifically (56.25 %) in males and (59.26%) in females. This was followed by calcium deficiency (48.96%) in males and (54.81%) in females, and vitamin B12 deficiency (16.5%) in males and (11.01%) in females. This study involved collecting random samples of vitamin D, B12, and calcium test results from routine health records of medical laboratories in Gharyan and its suburbs for 704 adults aged between 40 and 80 years, and estimating the prevalence of these vitamin deficiencies. A general paper questionnaire was administered to 100 adults to identify their financial and social status, the most common chronic diseases they suffer from, the types of vitamins they are deficient in, and the methods used to treat this deficiency, 55% of participants reported using dietary supplements. Then we selected 7 adults who had a severe vitamin deficiency under study, and we carried out therapeutic and nutritional interventions and introduced a separate dietary regimen consisting of dried figs and olive oil. These cases were followed up for a period of 3 to 4 months, and the rate of increase in these vitamins and the percentage of all cases were recorded. We found that the greatest improvement was observed in the case that relied on the use of dried figs and olive oil. The results showed a significant increase in both vitamin D and B12 levels. We also noted that the elevated iron stores (ferritin) in the blood results were associated with increased vitamin D levels. In addition, most cases that relied on supplements, injections, or tablets showed a significant increase in vitamin D levels.

This paper analyzes a power system of three regions, each independently responsible for meeting its daily load demands. The regions are interconnected via transmission tie lines, allowing maximum power capacity (MW) transfer in both directions. This study investigates the operation of the power system under different load conditions and examines the possible effects of power transfer limits on the reliability and efficiency of electricity supply across the regions. The research evaluates the optimal operation of generation units within each region while considering the constraints imposed by the transmission tie lines. It indicates that increasing the capacity of transmission tie lines would greatly improve power transfer between regions. Our findings discover that strategic coordination between the regions significantly enhances the system efficiency, reduces generation costs, and minimizes the risk of load shedding during periods of high demand. Additionally, the paper analyzes the effects of different load demands and transmission capacities on system performance, highlighting the advantages of regional interconnections in enhancing energy resilience. The research also investigates the optimal unit commitment for the total load for the same daily load curve by using the quad program. Quadratic Programming allows a full quadratic cost function for each variable together with linear equality and inequality constraints, as well as lower and upper bound limits on the variables.

This study investigated the challenges encountered by English majors at the University of Gharyan when dealing with metaphorical expressions. Such expressions are often embedded within culture-bound concepts, providing nuanced meanings specific to particular linguistic communities. Consequently, the research aimed to identify the strategies employed by Libyan students in translating metaphors from English into Arabic. This was achieved by using a translation test comprising fifteen (15) purposively selected metaphors. The test was given to a sample of forty (40) fourth-year students at the Department of English language, Faculty of Arts and Science, Mazda. The subsequent, data analysis followed a mixed-methods approach, integrating qualitative statistical measures(percentage and frequencies) with a qualitative linguistic analysis based on Newmark's (1988) theoretical framework for metaphor translation. The findings reveal that while students perform well when translating culturally familiar metaphors or those with direct equivalents, significant difficulties arise with abstract and culture-bound expressions. The study concludes that transitional failures are primarily driven by a lack of cultural competence and an over-reliance on semantic fidelity at the expense of communicative resonance. Based on these results, it is recommended that explicit metaphor translation strategies and comparative cultural studies be integrated into the EFL curriculum to bridge the gap between linguistic proficiency and metaphorical competence. Furthermore, the study advocates for enhanced translation training through specialized sessions design to foster a more conducive learning environment.
