Purpose: Recently, various accidents and incidents occurred in our school environment, making it necessary to enhance teachers' competency in school safety management. To this end, this study was conducted to analyze the needs of teachers related to school safety management competency development. Methods: For this purpose, the existing teacher's task analysis related to school safety management was revised and surveys were conducted to measure teachers' present level, expectative level and importance of the items based on the task analysis. To analyze the data, Borich Needs Assessment and The Locus for Focus Model were used. Results: In the t-test between the teachers' present level and expectative level about school safety management, all 39 tasks were related (p<.001). The priorities in developing teachers' competency in school safety management were found to be the 6 tasks listed below: 'To deal with each type of accident,' 'To implement CPR and defibrillator,' 'To use fire extinguishers and fire hydrants,' 'To use descending life lines,' 'To give first aid,' and 'To cope with elevator accidents.' Conclusion: By utilizing the results of the teacher's competency and need assesment as components, teachers' training programs can be made more applicable to the school setting. In addition, more experience-based programs should be considered when designing teachers' training programs in order to apply the priority found from the teacher's need assessment.

If the participants in construction site safety management perform their duties in accordance with the provisions of the Industrial Safety and Health Act, the burden on safety managers would be minimal. However, the lack of specific work guidelines for each participating entity and the greater responsibility of the safety and health general manager than the management supervisor have resulted in safety managers' workload being increased due to the problem of management supervisors' neglect of safety management. In this study, we conducted a survey of the safety manager's duties and related documents during the construction project initiation, early stages, ongoing work, and disaster occurrence/investigation, and conducted interviews to improve and enhance the division of duties.

In order to improve the safety performance oi construction projects, effective and corporative safety management program between head office and job site must be implemented. And its performance must be measured and analyzed for the identification of the problems in the safety management area. This study proposes a previous evaluation model of safety performance for the large construction firm in order to enhance their safety level. The fundamental data for proposed model is based on the past research(Son 2002), which is structured of evaluation criteria. weighted factor. statistical evaluation formula. The model would help the firm management in identifying the weak areas of safety performance in terms of the degree performing certain safety tasks. It is expected that the model could contribute to achieving the "zero accident" level.ot; level.

The purpose of this study was to investigate the status of school nutrition education and changes in perception of nutrition teacher's job in order to determine the need for redesign to achieve their ideal job. The questionnaire was distributed to 1,550 nutrition teachers, and a total of 1,487 usable data were collected with a 96% response rate from August to December 2015. Statistical data analysis was completed by using SPSS/Win 21.0 for descriptive analysis. The results were as follows: 45.5% of nutrition teachers periodically implemented nutrition education classes, and 32.7% of responses used creative activity times for nutrition and dietary life education. Various topics were taught such as strategies to improve dietary habits, choice of healthy foods and nutrition labeling, nutrition information, food safety, and environmental problems, etc. Current performance ratios of nutrition teacher's duties and tasks were as follows: nutrition operation 31.3%, foodservice hygiene and safety 28.0%, nutrition management 22.7%, nutrition and dietary life education and counselling 11.6%, and professional development 6.4%. Opinions about ideal job performance of nutrition teachers were investigated to determine needs for job redesign. Two in nutrition management duty tasks and four foodservice management duties duty tasks were reduced. On the other hand, another two nutrition management duty tasks and three nutrition and dietary life education and counselling tasks were increased compared to current job performance.

A survey was conducted on safety and health managers to analyze what change have occurred in the safety health management system of companies since the enforcement of the Serious Accidents Punishment Act. As a result, it was confirmed that most of the safety and health budgets increased, and most of the safety and health organization operations and safety and health tasks were strengthened. However, further research is needed to see if this has a practical effect on worker safety and reduction of serious accidents, and realistic measures are needed to allow safety and health managers to focus on practical helpful tasks rather than formal ones. In addition, it was confirmed that active support from business owners or management managers and strengthening education on the Serious Accidents Punishment Act were needed through cross-analysis between the education of the Serious Accidents Punishment Act and positive change in safety and health.

LPG refueling include a lot of risk done by human beings, dealing with highly combustible gas, so, during the refueling, the leakage initiated by human errors can result in a catastrophic accident. Therefore, this research tried to show what kind of tasks would include the high probability of the human errors and what should be considered for effective safety management in the LPG refueling. At first, 4 typical cases were taken through surveying various accident cases, and then a prototype of the refueling task was presented. And each task was analysed by FTA and ETA. The results showed that overpressure occupies 64.64% of the major reasons for gas leakage, and its probability was approximately 6.62E-06. Among the tasks, gas leakage resulted from mal-assembly of lorry hoses had the highest rate, and human errors related to opening and closing valves of pipe lines were most frequent. Also, the effects of confirming tasks were analyzed quantitatively.

An efficient measurement and evaluation system for hand tool tasks will provide a practical solution to the problem of designing and evaluating manual tool tasks in the workplace. Few studies on the biomechanical analysis of hand postures and tool handling tasks exist because of the lack of appropriate measurement techniques for hand force. A measurement system for the finger forces and joint angles for analysis of manual tool handling tasks was developed in this study. The measurement system consists of a force sensing glove made from twelve Force Sensitive Resistors and an angle-measuring glove (Cyberglove$\^$TM/, Virtual technologies) with eighteen joint angle sensors. A biomechanical model of the hand using the data from the measurement system was also developed. Systems of computerized procedures were implemented integrating the hand posture measurement system, biomechanical analysis system, and the task analysis system for manual tool handling tasks. The measurement system was useful in providing the hand force data needed for an existing task analysis system used in CTD risk evaluation. It is expected that the hand posture measurement developed in this study will provide an, efficient and cost-effective solution to task analysis of manual tool handling tasks. These tasks are becoming increasingly important areas of occupational health and safety of the country.

This study aims to compare six observational methods for assessing arm- and hand-intensive tasks, based on literature review. The comparison was conducted in viewpoints of body regions, force/external load, motion repetition, other factors including static posture, coupling, duration/break, pace, temperature, precision task, and final risk or exposure level. The number of risk factors assessed was more, and assessment procedure was more complex than the observational methods for assessing whole-body postural loads such as Ovako Working Posture Analysis System(OWAS), Rapid Upper Limb Assessment(RULA), and Rapid Entire Body Assessment(REBA). Due to these, the intra- and inter-reliabilities were not high. A past study showed that while Hand Arm Risk Assessment Method(HARM) identified the smallest proportion of the work tasks as high risk, Strain Index(SI) and Quick Exposure Check(QEC) hand/wrist were the most rigorous with classifying most work tasks as high risk. This study showed that depending on the observational technique compared, the evaluation factors, risk or exposure level, and evaluation results were different, making it necessary to select a technique appropriate for the characteristics of the work being assessed.
