The objectives of this study is to analyze the curriculum based on the hypothesis of bodyguarding related department and to research the differences of the amongthree groups of public bodyguarding, private bodyguarding and bodyguarding professors with its significance in order to establish the development of direction in education curriculum for bodyguarding related departments at university level,For this purpose, this study categorized the sample group into three kind and surveyed them, Those are public bodyguarding members, private bodyguarding member, and the professors and 121 samples were selected in those three with the help of self-admistrated method, which is one of the sampling methods, First, among the current bodyguarding related theoretical disciplines significant differences among groups was presented by the evaluations on bodyguarding science, traffic safety management, fire extinguishing, secretary science, administration, psychology, sports education, sport physiology, jurisprudence and philosophy, which showed differences among groups through the multiple comparison, But there was no significant difference among the means of the groups concerned with the other curriculum, We could know that more curriculum is needed to facilitate the private bodyguarding in disciplines and system of the current theory in this study. For it is predicted the demand for the private bodyguarding will increase continuously in the future. for which we should prepare. Thus it is required to increase the theoretical curriculum of the private bodyguarding. That is. the models of curriculum like introduction to machinary guarding. introduction to communication. computer theory and so on are required to be established. In addition to that. it must be noticed that the current private bodyguarding is not guaranteed by the legitimate institution. But the private bodyguarding is related to the police service. thus the curriculum of jurisprudence and police science should be studied together.

Firemen are directly exposed to various harmful chemicals, physical factors and mental stress during rescue and fire-fighting. In fire extinguishing, unstable posture, poisonous gas, dust, high temperature and heavy equipments are possible hazardous factors. The alertness for emergency, shift work, job strain and stress are also possibly hazardous. Therefore, this study aimed to investigate the prevalence of musculo-skeletal symptoms and job stress and to determine risk factors in firemen. This study was carried out in a group of 226 firemen in Busan City, Korea. Standardized Nordic Questionnaire was used to investigate the prevalence of musculo-skeletal symptoms and Psycho-social Well-being Index (abbreviated PWI) was used to investigate the prevalence of job stress. General and occupational characteristics were included education, marital status, alcohol and smoking history, working duration, and work shift system. Body mass index (BMI) scores were calculated by physical examination including height and weight. Concerning musculo-skeletal complaints, the commonest site was neck, and shoulder, lower back, upper back were the next. Complaint site above one area of body was about 80%. From multiple logistic regression analysis, working duration was significant variable in musculo-skeletal symptoms. Odds ratio were 15.4 in working duration. About 16.8% was high risk stress group. From multiple logistic regression analysis, shift work and alcohol drinking were significant variables in PWI scores. Odds ratios were 2.25 in shift work. Accordingly, interventions are needed for health promotion of long term and shift worker.

본 논문에서는 최근 사용이 증가하고 있는 몰드변압기의 난연성을 확인하기 위해 연소시험을 하였다. 먼저 지하철 변전소의 몰드변압기 설치현황과 호선 및 제작사별로 정류기용변압기와 고압배전용 변압기의 장애현황에 대하여 조사하였다. 다음으로 수평가열로내에 실제 몰드변압기의 고압 권선부를 설치하고, KSF 2257(건축구조 부분의 내화시험방법 : 1993)의 표준 가열 온도 곡선에 의해 가열하였다. 몰드변압기의 연소특성을 파악한 결과, KSF 2257 연소시험곡선에 의한 완전연소까지는 78분이 소요되었으며, 착화후 수평로 가열을 중지한 후 화염의 진행상황을 확인한 바 화염의 진행이 되지 않았으며, 자기소화특성을 나타냄으로써 몰드변압기의 난연성 및 자체 소화성을 확인할 수 있었다. 본 연구 결과 몰드변압기의 사고는 단락 및 과부하 등에 화재사고 보다는 몰드내 다른원인에 의해 사고 진전이 확대됨을 확인할 수 있었다.
