In Kenya during the last one decade, public and private sectors have invested a lot of resources in computer based Information and Communication Technologies (ICT) to improve the quality of education in schools. The main objective has been to integrate ICT in the delivery of curriculum in order to improve the quality of teaching-learning and to produce ICT literate workforce. The computer based technologies are used in management, pedagogy, and communication. This paper presents results from a study that was conducted in Nairobi County in Kenya to determine the key factors in the integration of computer based ICT in teaching-learning in pre-primary and lower primary schools. Results had revealed that the use of computer based ICT in teaching-learning by both pre-primary and lower primary schools was influenced by accessibility of resources, capacity to use the technology, availability of time, and provision of technical support.

Multiple U-typed production lines are increasingly accepted in modern manufacturing system for the flexibility to adjust to changes in demand. This paper considers multiple U line balancing with the objective of minimizing cycle time considering of moving time of workforce given the number of workstation. Like the traditional line balancing problem this problem is NP-hard. In this paper, we show how genetic algorithm can be used to solve multiple U line balancing. For this, an encoding and a decoding method suitable to the problem are presented. Proper genetic operators are also employed. Extensive computational experiments are carried out to show the performance of the proposed algorithm. The computational results show that the algorithm is promising in solution quality.

Since the competitive environment, it has become common for firms to reduce its workforce to diminish operating cost. Accordingly, job insecurity among employees has been increasing. Previous works on job insecurity have not paid adequate attention to the influence of job insecurity on safety behavior. The current paper investigates the impact of job insecurity on safety behavior and its intermediating mechanisms. In specific, this paper delves into the mediating effect of job stress, as well as the moderating effect of servant leadership in the association between job insecurity and job stress. The results demonstrated that that job insecurity has a positive (+) influence on job stress, which has a negative (-) influence on safety behavior. Moreover, job stress mediated the association between job insecurity and safety behavior. Furthermore, servant leadership moderated the job insecurity-safety behavior link.

The construction industry is an integral part of any nation's economy, whether measured by dollar volume or workforce size. In spite of its strong influence, there has been very little specifically aimed at evaluating the current industry performance. This research investigates the macroeconomic performance of the construction industry by accounting for crucial performance affecting factors such as labor productivity and gross margin. A clustering analysis, followed by a series of statistical analyses, yielded a notable finding that labor productivity is the most important factor that affects industry's profitability. The results of the analysis also revealed that the states with the strongest labor productivity show the highest level of profitability in terms of gross margin. This study should be of value to decision-makers when plotting a roadmap for future growth and rendering a strategic business decision.

The research question in this study was to see whether there were similarities and differences in HR practices of IT-based companies in Korea. Interviews with 12 HR executives and a survey of 51 IT-based companies showed that there were IT industry-specific HR practices, but no group differences except one. The only one difference between two groups (small- and medium-sized firms versus multinational corporations) indicated that the latter was better positioned in various HR practices. Four HR themes emerged from analyses of interviews and a survey data: business environment, workforce management, HR practices, and HR for competitive advantage. The fact that none from large companies was found to have female HR executive calls for an in-depth study of what is occurring and what could be done to better the workplace in terms of diversity. A large-scale study using diverse methods in the future will produce more meaningful findings on HR practices in IT-based firms in Korea.

This research endeavors to explore the enhancement of workforce economic efficiency through the application of nanotechnology, focusing on its economic implications. The findings of this investigation reveal that in recent years, surging global population growth and escalating demands for products and services have led to excessive resource consumption, resulting in adverse environmental consequences and altering environmental conditions-a phenomenon referred to as the economic growth dilemma. Entrepreneurs and economic stakeholders have begun to recognize the importance of sustainable development and the integration of environmental considerations into the production of goods and services. Within this context, knowledge-based economies have emerged as a driving force for sustainable business practices, particularly in the realm of nanotechnology. The integration of nanotechnology across various industries, including pharmaceuticals, agriculture, environmental management, and the chemical and petroleum sectors, as well as energy distribution, has yielded remarkable results. Consequently, this research aims to investigate the application and integration of nanotechnology in environmentally friendly silver nanoparticle production within select industries. Subsequently, it will examine the far-reaching implications of nanotechnology on economic growth and sustainable development.

Almost accidents in construction sites are occurred by unsafe work conditions and failure making safe environment. As recent construction projects become more complex, various and diversified, So the potential of construction-related accidents is increased as well. Comparing the frequency of construction-related accidents in large-sized construction sites, small-sized construction sites are more vulnerable because of lack of workforce and less effective technology system. Furthermore, the absence of safety committee, poor financial condition leads to lack of safety education, installation of safety facilities, and provision of individual protective equipment, which indicates difficulties handling even basic safety management. Therefore, in order to lower the hazard rate at small-Sized construction sites, it is necessary to proceed with more structural and thorough actions for preventing accidents. In other words, it is necessary to analyze the causes of the accidents at small-sized construction sites, set criteria for safety management, and suggest safety management items according to work classification by evaluating the relative importance of the items.

In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.

산업보안관리사는 현재 민간자격이지만 향후 국가자격화 되어 현장에서 적절하게 활용 가능한 인력인지 여부에 대하여 국가적으로 공신력이 부여될 필요가 있다. 공신력 확보를 위한 운용방안 중 고려할 수 있는 것이 등급제이다. 현재와 같이 단일등급제로 운용할 경우 양적 확산에 초점을 두게 될 가능성이 있다. 따라서 질적 혁신 차원에서 산업보안관리사의 등급제도 활용도를 장기적인 관점에서 검토하여 등급을 구분할 필요가 있다. 한편, 산업보안 현장 실무자의 산업보안관리사 자격시험에 응시할 수 있는 요건, 산업보안 실무연수 과정 이수, 민간자격을 이미 취득한 인력의 경우 국가자격 승계문제도 중요한 고려 사항중 하나이다. 산업보안관리사제도가 활성화 되기 위해서는 국가자격화를 통한 공신력 확보뿐만 아니라 산업보안관리사의 인력의 수요창출이 필요하다. 현재 증가하는 산업기술유출에 대한 우려에도 불구하고 우리기업 등의 보안관리체계의 미비 등 산업보안대응 역량이 상당히 취약한 실정임을 고려할 때, 산업기술 보호에 특화된 산업보안관리체계에 대한 인증을 기존의 정보보호관리체계인증과 별개로 도입할 필요성이 있다. 산업보안 관리체제 인증제도와 산업보안관리사 자격제도가 연동될 때 국가핵심기술 등을 다루는 기업체, 연구기관 등의 산업보안이 실질적으로 이루어져 시너지 효과가 발생할 것이다.
