We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea, using the following 5 inspections items: "putting into warehouse (A)", "prevention of cross-contamination (B)", "storage management (C)", "temperature control (D)", and "management of records and documents (E)", We included 20 detailed items. The results of distribution for frequency by five major inspection items showed that "(E)" was the highest, the next "(D)", "(C)"; and "(B)" was the lowest. In the correlation of inspection scores between total scores, "(B)" and "(C)" were highly related to the total score, therefore, the higher score of "(B)" or "(C)", the higher for the total score. In details of inspection items, "the management of cross-contamination upon taking product out of the warehouse" had the lowest score with a mean, of $2.67{\pm}1.80$, and also ranked as first of the 20 items.

In the case of precise safety inspection and precise safety diagnosis of a building, a condition evaluation must be conducted to determine the safety grade. Since 2004, an evaluation method using fuzzy theory has been introduced for quantitative condition evaluation,and the relationship and importance of reinforced concrete members using fuzzy theory have been applied. Generally, fuzzy theory is a method used to deal with ambiguous expressions with unclear correlations, but at the time of development, it seems that it was developed by applying fuzzy theory as an alternative in a situation where inspection and diagnosis result data were insufficient. Therefore, it is necessary to verify the relationship and importance of evaluation items derived based on the current fuzzy theory using actual inspection and diagnosis result data.In this study, the correlation between the evaluation items was derived by using the results of 19 precision safety inspections and 9 precision safety inspections and the performance score function formula, and using this, a reasonable durability score calculation formula of the member was presented.

As buildings become higher and larger, the possibility of accident also increases, and recurrent accidents and serious accidents are also increasing. However, it is not possible to control all the hazardous activities in construction site. Therefore, hazardous activities with higher possibility should be identified and prioritized in advance so engineers and managers can control the activities in safe manner. For this purpose, this research adopts FMEA technique, which has been widely utilized in manufacturing industry. In order to apply FMEA technique in construction safety management, the process of construction work is divided into sub-processes or activities. Then FMEA technique is applied to quantitatively analyze the importance of each activity from the safety perspective.

For advanced construction safety, there frequently are repeated accident. Most of them are serious disasters which are continually concerned. But technical method of Safety organizations for construction project is still short, simple and unscientific. We suggest FMEA(Failure Mode and Effect Analysis) process on the safety management. The purpose of study is an establishment of safety system focused on scientific method by selecting priority unit and by figuring importance.

1996년부터 유럽연합을 중심으로 전자파내성(Electromagnetic immunity; 흔히 군사규격에서는 전자파감응성(electromagnetic susceptibility)이라 함) 규제가 본격적으로 시작될 전망이다. 이러한 전자 파내성 규제는 우리가 과거 '80년대 초에 경험했던 전자파방출(electromagnetic emission; 흔히 electro- magnetic interference 라고도 표현한다) 규제에 비해 규제주파수가 대폭 확장됨(9KHz - 1GHz .rarw. 50/60 Hz - 40 GHz)은 물론, 규제항목도 크게 늘어나기(2개 항목 .rarw. 11개 항목)때문에 본격 규제가 시작되면 우리 산업체에 큰 피해를 초래할 것으로 우려된다. 특히 "복사 전자기장에 대한 전자파내성 요구사항"은 일부 전자파내성 측정항목을 포함하고 있던 안전규 격 등에서도 다루고 있지 않던 것으로서 우리에게는 매우 생소한 항목이다. 이 항목은 과거 미국의 군사 규격등에서 요구했던 항목인데, 앞으로 각국의 상용규격에도 대폭 추가될 것으로 보인다. 이러한 규제는 우리의 생활환경에서 결코 빼놓고 생각할 수 없는, 동시에 가장 큰 전자파장해원인 의도적 복사로서의 방 송신호 및 각종 무선통신 신호에 대해 전기, 전자기기가 전자파내성을 갖고, 성능저하나 오동작을 유발하 지 않아야 함을 요구하는 것이다. 이러한 항목의 평가를 위해서는 대형 시험환경(EMS chamber)과 표준 전자기장 발생장치(signal genera- tors + high power amplifiers), 그리고 오동작 모니터링 장치(monitorring equipments) 등이 필요하기 때 문에 평가시스템 구성에 막대한 비용이 소요된다. 따라서 시스템 구성에 매우 신중을 기해야 하며, 관련 국제표준화규격을 사전에 철저히 이해하여 관련 시험검사를 위한 투자계획을 수립하는 것이 바람직하다. 본 고에서는 복사 전자기장에 대한 대표적인 국제표준화규격을 소개하고, 나아가서 그러한 항목의 평가 시스템의 설계 및 구현에 대해서 설명할 것이다.

The purpose of this study was to examine safety accidents related to school foodservice, working and operating environments of school foodservice, status and awareness of safety education, educational needs, and information on qualitative improvement of school foodservice. The subjects in this study were 234 cooks in charge of cooking at elementary and secondary schools in Chungbuk. A survey was conducted from July 30 to August 8, 2012, and among 202 questionnaires gathered, 194 completed questionnaires were analyzed. Statistical analyses were performed on data utilizing the SPSS version 19.0. The main results of this study were as follows: 44.3% of workers experienced safety accidents. The most frequent safety accident was 'once' (60.5%), and most safety accidents took place between June and August (31.4%). The time at which most safety accidents happened was between 8 and 11 am. Most safety accidents happened during cooking (52.3%) and while using a soup pot or frying pot (52.4%). The most common accidents were 'burns', 'wrist and arm pain', and 'slips and falls'. Respondents who experienced safety accidents replied that 57.6% of employees dealt with injuries at their own expense, and only 35.3% utilized industrial accident insurance. In terms of the operating environment, the score for 'offering information and application' was highest (3.76 points), whereas that for 'security of budget' was lowest (1.77 points). As for accident education, employees received safety education approximately 3.45 times and 5.10 hours per year. Improving the working environment of school foodservice cooks requires administrative and financial support. Furthermore, educational materials and guidelines based on the working environment and safety accident status of school foodservice cooks are required in order to minimize potential risk factors and control safety accidents in school foodservice.

This study was performed to develop an analytical method in specified wastes for preventing the environmental pollution from hazardous wastes. Few analytical methods were developed using the waste standard reference materials of sludge, waste oil, bottom ash, etc. which contain As, CN, Cd, Cr, Cu, Pb, and Hg compounds. The pre-treatment method was considered by whether or not the synchronous analysis is possible. Waste samples obtained from the 34 representative facilities, which are emitting the hazardous substances, were analyzed.

This paper reports on three Delphi surveys based on draft evaluation items with the aim of deriving evaluation items prior to developing a BF certification index for school facilities in order to make the index safe and convenient. To this end, problems were formulated using content analysis and follow-up evaluation of existing BF certification indicators. Draft BF certification evaluation items for school facilities were proposed. The adequacy of each evaluation item was verified using a Delphi survey. Experts and working-level groups, such as university professors, architects, public officials, certification agencies, and organizations for disabled persons, provided feedback for all evaluation items for school facility BF, which was incorporated in the final evaluation items. As a result of the Delphi surveys, in addition to the existing 8 evaluation items, a total of 75 evaluation items were proposed as maintenance items, 12 as improvement review items, and 15 as new evaluation items.
