Fuel cell systems are a completely different form of electricity source that has been used so far and is an aggregation of multiple technologies with multidisciplinary features that can be operated safely only when gas and electrical safety are being considered. Since fuel cells generate through electrochemical reactions there are difficulties in ensuring electricity safety, power quality assessment, effective control and reliability standards for system faults using conventional inspection techniques and even though they are necessary as a primary means for reduction of CO2 owing to the Climate Convention, electrical safety assessment and measures are required for the prevention of faults in residential facilities. Although small-scaled distributed power supplies can be utilized as important means of peak control and energy management measures, research is required for observing the effects on the system and the development of inspection technology to ensure stable operation, and the electrical safety of residential fuel cell systems need to be assessed and the problems derived for establishing electrical safety standards. From the year 2002, Japan has established laws on technical safety standards and development and rules on the product specifications and standards for the industrialization of hydrogen fuel cells. Also, a lot of effort have been made for the commercialization of fuel cells by building one-stop certification services. Internationally, the IEC TC 105 has established international standards based on fuel cells. In order to protect the national interest, the country should be able to respond accordingly meet global standards. In fact, in Korea, to comply with the international trend, Korea Energy Management Corporation is establishing a certified agenda for fuel cells and Korean Agency for Technology and Standards is enacting technical standards for fuel cells. The current terms of fuel cells are that research has been focused more on the quality and performance of manufactured products rather than stable power operation and maintenance over time. In this paper, by considering the household fuel cell as a power device, the safety standards of the fuel cell system for a reliable operation with the existing power system is being proposed.

"Detailed Nondisclosure Standards" of an institution include subject information and rationale that should not be disclosed by the institution. According to the Information Disclosure Act, such standards must be established in consideration of the nature of work, and continuous implementation is required. However, studies that reviewed the purpose and role of "Detailed Nondisclosure Standards" or the status of public institutions' development and operation of such standards were insufficient despite such standards being an indispensable tool in practice and a major device to protect the people's right to know. Therefore, this study introduces the strategies of the public institution and the research team to develop detailed standards for nondisclosure through the case of institution A. This will be of practical help to public institutions that intend to develop detailed nondisclosure standards in the future based on communication between institution A and the research team and sharing details during the project process.

Due to the distribution structure of domestic temporary equipment, quality control of temporary equipment is essential because more than 80% of temporary equipment is repeated and reused. Due to this importance, the Ministry of Land, Infrastructure and Transport has proposed quality management standards for temporary equipment for 10types of temporary equipments, including steel pipe support, but the overall quality of temporary eqipment cannot be confirmed because the quality is managed through sampling quality tests. In addition, although quality control standards exist for temporary material rental company, practical utilization was investigated and analyzed to be very low as they are mainly presented based on qualitative inspection standards by visual inspection. Therefore, the purpose of this study is to develop individual temporary material/quality/delivery management standards (Guides) for temporary equipment rental company to preemptively secure the quality of temporary equipment before bringing them into the construction site. If the standards developed through this study are applied to domestic temporary equipment rental companies, it is expected that high-quality temporary equipment with secured quality will be brought into the construction site as the quality of temporary equipment quality of domestic medium and small temporary equipment rental companies is improved safety accidents related to temporary structures.

Purpose: The purpose of this study is to provide basic data for a more reasonable health teacher placement policy sending teachers to more appropriate sites, by analyzing the change process of the health teacher placement standards and the problems caused by an unreasonable placement policy. Methods: This study mainly analyzed relevant research data and existing studies focusing on a literature analysis. Results: To date, the placement policy for health teachers has changed, going through expansion, reduction, and retrogression, since its establishment. The standard, placing health teachers only in elementary schools with more than 18 classes, was created in 1952. Despite the expansion of the role of health teachers and the revision of the school health law in 2007, this standard has been applied to date without modification. In the meantime, there have been many problems caused by inappropriate placement of health teachers. It was difficult for health teachers in large schools to carry out proper health education; and, in many schools, passive health management, such as first aid, health tests, and student health management, was mainly executed rather than active health management. Students in small schools were not even given an opportunity to receive health education and health management owing to the absence of health teachers. Also, compared to teachers teaching other subjects, health teachers have had very unfair placement standards. Conclusion: The placement policy for health teachers, which has been applied to the present, has never reflected social change, the increase of student health issues, and the demand from the school area. Although the role of health teachers expanded with the execution of health education, the current placement standards for health teachers are very unreasonable. Accordingly, it is necessary to review the health teacher placement policy in a reasonable manner and to revise the standards considering the reality.

The purposes of the study were to examine food purchasing management practices and to assess dietitians' awareness on food quality standards, use of food purchasing guidelines(food quality guidelines, supplier selection criteria), and organizational collaboration related to purchasing at school food service. A total of 400 dietitians working at elementary schools in Kyunggi Province were surveyed and 247 responses were returned. Excluding responses with significant missing data, 240 responses(60%) were used for data analysis. Compared to the previous reports, competitive bidding and shorter contract periods were preferred for purchasing food supplies. A dietitian, school staff, and food service staff participated in receiving and inspection together at 58.4% of the schools. An average score of the dietitians' awareness on the food quality standards was 3.28 based on a 5-point scale(1:strongly disagree, 5:strongly agree). Their awareness scores for the quality standards related to the genetically modified organism foods, organic foods, and pesticide residues were the lowest. The awareness scores increased significantly with their age(p<.001). In general, the food purchasing guidelines were used well at the schools ; the usage levels of the food quality guidelines and supplier selection criteria were significantly different by length of operation(p<.05) and dietitians' age(p<.05), respectively. The dietitians' perception score of the organizational collaboration related to purchasing was rated 3.46 and differed significantly by dietitians' educational background(p<.05). For improving food procurement management, standardized food quality and purchasing criteria need to be developed. As the demands on high quality food supplies increase for school food service, the dietitians should improve their knowledges on the food quality standards and implement effective and creative purchasing methods.
