Sawmilling industry remained a high risk with the average 4.73% of industrial accidents in 2010-2012 that was eight times that of general manufacturing. Sawmilling industry had 200 industrial accidents victim in average. Manufacturing process in sawmill industry contained dangerous machinery such as conveyors, roller, saw ( band saw, circular saw) etc. It may be effective to figure out the type of industrial accidents occurred in the past and extend risk assessment which can predict hazard such as near miss when implementing exposure or potential dangers in sawmill industry. This study conducted research on the actual condition on the place of industrial accident occurrence, detailed work and contact object when injured, and injured part targeting 643 businesses which had industrial accidents in 2010-2012. As the results, RPN of general sawmill industry was the highest 'ganglip saw' with 36,157. RPN of the following order were 'moving truck' with 25,454, 'special machining operations' with 22,283. Also, probability of general sawmill industry was a lots within 1 year, while risk appeared a lots within 5 years. So, risk assessment shall be needed to emphasis on accident prevention of sawmill industry. And additional work will be needed on the risk assessment in hazard prevention work of supervisors.

This paper is written following an analysis of occurrence trend of industrial disaster in manufacturing industry. One of major reason of industrial accident is unsafe action caused by lack of work supervision. so we have surveyed the understanding level of supervisors for industrial safety and their education of industrial safety which is forced by industrial law. We have got the result that the supervisor's education is necessary to prevent industrial disaster but it's not fit for their own workplace for various reasons from the survey and analysis. I would like to suggest effective solutions. The institute of education should train that they can execute safety and health works themselves by classification of the industrial category, company scale and located region. Also, government should endow supervisors with authority and responsibility for the activation of education system. Finally, government should support the expense of education to medium and small-sized enterprises especially, and they should be interested in the attendance and execution of education. They will achieve the goal to prevent industrial disasters in manufacturing industry through the enforcement of effective supervisor system as per the remark mentioned above.

This study is purposed to research the present status and outcomes of adaption of science teacher system in elementary school. The subjects of this study are science teachers, schoolmasters, science supervisors, and 3rd$\~$6th grade students in western office of board of education, Gwangju Metropolitan city. It was found that there are 264 teachers who teach one subject and only two of them were science teachers. In elementary schools, most classroom teachers didn't want to be science teachers and schoolmasters or science supervisors could not afford to adapt science teacher system. After applying science teacher system to 3$\~$6th grade students during one school year, many students were improved in academic achievement and inquiring ability, and they have increased of interest and participation in science activities. This means that science class by science teacher is more effective than that by classroom teacher. Therefore, science teacher system should enlarge to science class in elementary school.

Background: The purpose of this study was to identify the influence of workers' perceived workload, accident experiences, supervisors' safety leadership, and an organization's safety climate on the cognitive and emotional risk perception. Methods: Six hundred and twenty employees in a variety of manufacturing organizations were asked to complete to a questionnaire. Among them, a total of 376 employees provided valid data for analysis. To test the hypothesis, correlation analysis and hierarchical regression analysis were used. Statistical analyses were conducted using IBM SPSS program, version 23. Results: The results indicated that workload and accident experiences have a positive influence and safety leadership and safety climate have a negative influence on the cognitive and emotional risk perception. Workload, safety leadership, and the safety climate influence perceived risk more than accident experience, especially for the emotional risk perception. Conclusion: These results indicated that multilevel factors (organization, group, and individual) play a critical role in predicting individual risk perceptions. Based on these results, therefore, to reduce risk perception related with unsafe behaviors and accidents, organizations need to conduct a variety of safety programs that enhance their safety climate beyond simple safety-related education and training. Simultaneously, it needs to seek ways to promote supervisors' safety leadership behaviors (e.g., site visits, feedback, safety communication, etc.). In addition, it is necessary to adjust work speed and amount and allocate task considering employees' skill and ability to reduce the workload for reducing risk perception.

In the knowledge development of online assessment in learning management systems (LMSs), many assessments are evaluated weekly in the summer training course for undergraduate students in the Faculty of Computing and Information Technology at King Abdul-Aziz University in Saudi Arabia. The number of performance assessments in the summer training course reaches 15 weeks. Many of them, however, are sent or done informally or through unreliable ways and cannot be verified by third parties. Therefore, applying the concept of digital transformation is essential. This research study reported herein used the action design research (ADR) method to build a new information technology system that could assist in the digital transformation. An electronic platform was designed, developed, implemented, and evaluated using the ADR method so that the main people involved in the summer training process (i.e., students, academic supervisors, and administrators) would have a high level of satisfaction with it. The study was conducted on 452 students, 105 academic supervisors, and 15 administrative staff and was conducted during the summer semester of 2020. All the training processes were digitally transformed and automated to control and raise the level and reliability of the training. All involved people were satisfied, thus, shifting the process to be in a digital form assist in achieving the high-level goal.

Chemical accidents are increasing day by day as the industry develops. To prevent such chemical accidents, Korea enacted the Chemicals Control Act. Through these laws, systematic management of chemical substances began. There are various positions in the companies. hazardous chemical supervisors, equipment and technical human, operators and employees. Chemicals-related education for each position should be provided. As a result of the survey, hazardous chemical supervisors and equipment and technical human liked the overall content of the Chemicals Control Act and the education subject on safety management standards for facilities. Conversely, the operators liked the course on how to wear personal protective equipment. The employees preferred subjects such as classification of chemical substances and prevention of chemical accidents. Currently, various modular textbooks are widely available. Rather than general education, it is necessary to select and provide customized subjects that are preferred and interested according to the position. Then it will be more effective in understanding harzardous chemical substances and in preventing chemical accidents.

The impact of supervisory communication apprehension (SCA) on subordinates' job performance was investigated in this study. We also examined the impact of task-related uncertainty in mediating the relationship between SCA and subordinate work performance, as well as the role of information-seeking behavior in moderating the relationship between task-related uncertainty and subordinate job performance. A sample of subordinates and their supervisors from public and private sector enterprises in Pakistan were used in the study. The concept of communication apprehension is not limited to a single organization or industry, and the conditions suggest that apprehensive supervisors are likely to exist in different organizations and industries in Pakistan, including banks, telecommunications, and development sector organizations. Company directors and leaders of human resources departments were contacted to reach out to possible respondents. SmartPLS software was used to evaluate the data using a structural equation modeling technique which is commonly used in explanatory studies (Atta et al., 2021). We found evidence to support ideas predicting the association between SCA and subordinate job performance, as well as the mediating role of task-related ambiguity in the relationship. Furthermore, the findings show that information-seeking activity has a moderating effect on the link between task-related ambiguity and subordinate job performance. This is one of the first studies to look at major mediating and moderating mechanisms in the link between SCA and subordinate job performance.

This study focuses on safety behavior among research workers and investigates the factors influencing their safety behavior. The selected variables for examining their impact on researchers' safety behavior are safety leadership, safety climate, and safety motivation. Surveys were conducted to analyze the structural equation modeling among these variables. The results indicate that the safety leadership of research supervisors positively influences the creation of a safety climate in research laboratories. Additionally, the safety climate positively impacts research workers' safety motivation and behavior. Therefore, to enhance the safety behavior of research workers, it is necessary to strengthen safety leadership education to improve the safety leadership of laboratory supervisors. The laboratory can enhance its safety climate by implementing management policies and safety regulations, fostering communication among members, and providing safety education.
