Abstract

Background. With increasing competition in the labor market, students must possess not only academic knowledge but also the practical skills and emotional readiness to transition into professional environments. Purpose. This study aims to evaluate the effectiveness of a career guidance program in improving students’ job readiness, focusing on key factors such as self-efficacy, communication skills, and career decision-making abilities. Method. A quantitative research design was employed, using pre- and post-surveys to assess the program’s impact on a sample of 300 high school students. The data were analyzed using descriptive statistics and paired sample t-tests. Results. The results indicate a significant improvement in students’ job readiness after participating in the career guidance program. The most notable gains were observed in self-confidence, the ability to make informed career decisions, and the development of job-search skills. Conclusion. The study concludes that career guidance programs are highly effective in equipping students with the necessary skills and mindset to succeed in the job market. Schools and educational institutions should prioritize the implementation of such programs to better prepare students for future employment opportunities.

Abstract

The Covid-19 pandemic has caused significant disruptions in daily life, leading to various mental health challenges, particularly among students. Sleep quality and depression are closely related, with poor sleep often contributing to higher levels of depression. During the pandemic, changes in daily routines, increased stress, and social isolation have likely affected both sleep patterns and mental health. This study aims to investigate the relationship between sleep quality and depression levels in students during the Covid-19 pandemic period. A cross-sectional design was employed, with 300 university students completing an online survey. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and depression levels were measured with the Patient Health Questionnaire-9 (PHQ-9). The results indicated that students reporting poor sleep quality had significantly higher depression scores compared to those with better sleep quality. A negative correlation was found between sleep quality and depression levels, with poorer sleep associated with higher depression severity. The study concludes that poor sleep quality is a significant predictor of increased depression in students during the pandemic. These findings emphasize the need for interventions targeting sleep improvement as part of mental health support for students during and beyond the Covid-19 crisis.

Abstract

The growing complexity of fluid simulations in computational science necessitates the use of high-performance computing (HPC) systems. Efficient processing is critical for handling large datasets and complex algorithms, particularly in fields such as aerospace, meteorology, and biomedical engineering. Existing parallel processing methods often face limitations in scalability and resource utilization. This research aims to optimize parallel processing systems for high-performance computing applications in fluid simulations. The study focuses on enhancing computational efficiency and reducing execution time while maintaining accuracy in simulations. A multi-faceted approach was employed, combining algorithmic improvements with architectural enhancements. The research involved implementing advanced parallelization techniques, such as domain decomposition and load balancing, on a cluster of HPC nodes. Performance metrics were collected to evaluate the impact of these optimizations on simulation speed and resource utilization. The optimized system demonstrated a significant reduction in execution time, achieving up to a 60% improvement compared to baseline performance. Enhanced load balancing techniques resulted in more efficient resource distribution, leading to improved overall system performance. Accuracy of the fluid simulations remained consistent with previous results, validating the effectiveness of the optimizations. The study concludes that optimizing parallel processing systems significantly enhances the efficiency of fluid simulations in HPC environments. The findings provide valuable insights for researchers and practitioners seeking to improve computational performance in complex simulations. Future work should explore further optimizations and the integration of emerging technologies to continue advancing the capabilities of fluid simulation in high-performance computing

Abstract

The interest in learning among elementary school students is a critical factor in shaping their academic success and lifelong learning attitudes. However, traditional teaching methods often fail to engage students, leading to a decline in their enthusiasm for learning. This study aims to develop a creative curriculum designed to cultivate elementary school students’ interest in learning by incorporating interactive and student-centered learning activities. The research employs a mixed-methods approach, combining qualitative data from classroom observations and interviews with teachers and students, along with quantitative data from pre- and post-intervention surveys measuring student engagement and interest in learning. The findings suggest that the implementation of a creative curriculum significantly increased students’ interest in learning across various subjects, with noticeable improvements in student participation, curiosity, and motivation. Teachers also reported higher levels of engagement and enthusiasm during lessons. This study concludes that a creative curriculum can effectively enhance students’ interest in learning by fostering a more dynamic, interactive, and personalized learning environment. The implications of this research highlight the importance of adopting innovative teaching strategies to ensure that students develop a lasting interest in their education.

Abstract

The shift to remote work has introduced significant challenges for leaders, particularly in balancing the need for organizational efficiency with the well-being of employees. The paradox of remote leadership lies in the difficulty of mitigating employee burnout Tan, Ewhile enhancing organizational citizenship behavior (OCB) through effective leadership. This study explores the relationship between digital transformational leadership, employee burnout, and OCB in remote work environments. The primary aim of this research is to investigate how digital transformational leadership can reduce employee burnout and promote OCB in remote work settings. A mixed-methods approach was employed, combining quantitative surveys and qualitative interviews. The survey assessed employee burnout, OCB, and perceptions of digital leadership, while interviews provided deeper insights into employee experiences. The findings reveal that digital transformational leadership significantly reduces burnout and enhances OCB. Employees who reported higher levels of leadership support and empowerment in virtual environments experienced lower burnout levels and higher engagement in extra-role behaviors. The study emphasizes the importance of digital leadership practices in fostering a healthy, motivated, and productive remote workforce. In conclusion, digital transformational leadership is essential for navigating the remote leadership paradox.

Abstract

The Komodo dragon (Varanus komodoensis), the largest living lizard, plays a crucial role in its ecosystem. Understanding its gut microbiota is essential for assessing its digestive efficiency and immune function, yet little is known about the microbial communities within its gastrointestinal system. This study aimed to analyze the gut microbiota of wild and captive Komodo dragons using metagenomic sequencing and to explore its role in digestion and immunity. Fecal and gut content samples were collected from 12 wild and 10 captive Komodo dragons. High-throughput sequencing of the 16S rRNA gene was used to characterize the microbial diversity. The results revealed significant differences in microbiota composition between wild and captive individuals, with wild dragons displaying higher microbial diversity. Dominant phyla in wild Komodo dragons included Firmicutes and Bacteroidetes, while Escherichia and Klebsiella were more prevalent in captive individuals. Additionally, microbial diversity was positively correlated with immune-related gene expression, suggesting that the microbiota plays a role in immune modulation. These findings highlight the importance of diet and environmental factors in shaping the gut microbiota, with implications for conservation and breeding programs. Further research should focus on functional profiling and exploring other microbial groups to fully understand the microbiome's impact on health
