This study investigated the comprehension of the occupational safety policy direction by job characteristics of the safety managers at 211 workplace selected under the Occupational Safety and Health Act. As for the characteristics of the subjects' firms, there was difference in their perception on the occupational safety policy direction by their region, type, scale, and the existence of labor union. Regarding the job characteristics of the subjects, there was difference in the comprehension of the occupational safety policy direction by their age, experience and department. This study suggests that the government policy as well as the awareness about safety by management and safety managers need to be changed by analyzing the comprehension of occupational safety policy direction by the job characteristics of corporate occupational safety managers.

고용노동부 산업재해분석 자료에 의하면 최근 5년간 (2006년～2010년)의 총 재해자 수(사망자수) 472,329명(11,662명), 경제적 직접손실액 16,814,806백만원, 경제적 손실 추 정액(직·간접) 84,074, 030백만원으로 인적·물적 손실이 크다는 것을 알 수 있다. 본 연구에는 산업안전보건법상의 안전관리자 선임된 사업장 211개소 대상으로 안전 관리자의 직무특성에 따른 산업안전정책방향 이해도에 관한 조사를 하였다. 연구대상 자의 기업체의 특성을 보면 지역별, 업종별, 규모별, 노조설립 여부에 따라 산업안전정 책방향에 대한 인식도 차이가 있는 것으로 나타났으며, 연구대상자의 직무특성을 보면 연령, 경력, 근무부서에 따라서도 산업안전정책방향에 대한 이해도 차이가 있다는 것 을 알 수 있었다. 본 연구에서는 기업체 산업안전관라자 직무특성에 따른 산업안전정책방향 이해도 분석을 통해 정부의 정책변화, 경영자·안전관리자의 안전의식 변화가 필요할 것으로 사료된다.

In this study, actual status of safety management for the objects of 173 university, government research institution, and corporate affiliated research center was carried out through questionnaires. For unexpected accident status according to kinds, scale, and types of laboratories, frequency analysis using cross analysis and multiple replies analysis was used. The result of this study is judged to be used for laboratory safety education prevention programs, laboratory environment improvement, investment or improvement of laboratories through the actual safety management status of laboratories such as vulnerable works for generation of unexpected sudden accidents according to kind, scale, and type of laboratories, period of occurrence, prevention education, necessity for preliminary test, and cause of laboratory accidents.

In this study, with the objects of 173 institutions of university and research institutions, investigation was carried out through visit investigation ar d questionnaire investigation. Frequency and severity of occurrences was acquired mainly through universities and research institutions which have reported occurrences of accidents to the Ministry of Education, Science, and Technology. Quantitative danger evaluation was conducted through frequency and strength of occurrences. Case study was carried out by selecting bio science laboratory of university and as the result of this study, degree of danger among the inspection objects of bio science laboratories, laboratory work place was evaluated as the most dangerous with the scores of 155.00 and as the result of average danger level, compression gas cylinder was evaluated as the most dangerous with the scores of 6.4000.

Recently, there are many research of musculoskeletal disorders in manufacturing industry because of increasing interest of that disorders, but the research is still lacking in the small business and service industry. So we researched relationship between working characteristics and subjective symptoms associated with musculoskeletal disorders by get information of 145 hairdresser about working hour, work record, position and working pattern. The results of this research show that there are many musculoskeletal disorders of hairdressers' neck, shoulder, arm, knee and also close relationship between working characteristics and subjective symptoms associated with musculoskeletal disorders. Besides, some parts of subjective symptoms have an effect on other parts of body. This information contributes to future reference and a precautionary measure about musculoskeletal disorders for hairdressers.

This study will contribute to using information and a precautionary measure about musculoskeletal disorders for hairdressers.

This research modified the checklist used in the universities in USA, England and Korea considering the current situation of Korea, and conducted case studies upon each section of appointed chemical laboratories based on 4M criteria, which stands for Machine, Media, Man and Management. The purpose of the studies is to assess how dangerous the laboratories are and to contribute to prevention of accidentsin the laboratories as well as reducing loss of lives and property. The result of this research found out the harmful and hazardous factors based on the 4M-type checklist and predicted the dangerousness as it multiplies possible frequency by intensity. Protective equipment, safety facilities in laboratories, emergency exit and compressed gas cylinder are found to be more dangerous, so the result shows that it is desirable to improve ventilation, safety facilities and circumstances of the laboratory through the investment.

본 연구는 캘리포니아 내 고속도로망을 대상으로 지진발생 후 교통흐름의 변화를 평가하는 기법에 대하여 이루어졌으며, 고속도로망 상에 위치한 교량의 손상정도가 평가기법의 가장 기본적인 요소로 사용되었다. 본 연구에 사용된 교량의 지진취약도는 PGA 또는 PGV의 함수로 나타내어졌고, 1994년 Northridge 지진과 일련의 시나리오 지진에 대하여 교통망 손상 평가를 수행하였다. 또한 교량 보수 및 보강 후 교통망에 대한 피해정도를 정량화하기 위해 확률모델을 개발하였으며, 그 피해정도는 시간(Drivers Delay)으로 나타내었다. 본 연구가 캘리포니아를 대상으로 이루어져 국내적용 및 활용가능성에 대해서는 후속 연구가 뒤따라야 할 것으로 사료된다.

Objectives: The aim of this study is to determine prevalence and related factors of musculoskeletal symptoms in electronics assembly line workers. Method: A questionnaire survey was performed on 350 workers in In-chon city. The questionnaire consisted of questions on the general characteristics, work duration, working hours, hobby activity hours, housekeeping activity hours and standardized descriptions of NOISH on musculoskeletal symptoms. Result: Complaint rates of musculoskeletal symptoms by anatomical site were as follows: shoulder, 67% : neck, 40.4% : waist, 28.7% : wrist and hand, 27.1% : foot and leg, 14.4% : arm and elbow, 11.2%. Significantly higher prevalence of shoulder musculoskeletal symptom was found women than men, married than unmarried, less than 1hours housekeeping activity than over 1hours housekeeping activity. Multiple logistic regression analysis identified gender, marital status and housekeeping activity as the main affecting factors for shoulder musculoskeletal symptoms. Conclusions: The most prevalence of musculoskeletal symptoms was shoulder site. It was higher in married women and over 1hours housekeeping activity in a day. It is recommended that married women should be reduce housekeeping activity time.

북방산개구리의 산란특성 및 발생과정을 연구하기 위하여 1998년 2월 중순에서 3월말까지 경기도, 경상북도, 강원도를 중심으로 남한의 전지역을 대상으로 표본을 채집하였다. 북방산개구리의 산란시기는 2월말에서 3월말사이에 주로 이루어지며, 산란장소는 정수지와 유수지를 모두 선택하나 유수지에 산란하는 경우 알의 형태는 뭉쳐진 불규칙한 공 모양으로 돌이나 수초와 같은 기질에 부착하며, 정수지의 경우 타원형의 계란모양을 이루고 기질에 부착하지 않는다. 발생과정

붉나무에서 오배자면충의 오배자 형성 기작과 오배자면충의 발육 및 붉나무 잎 부위별 오배자 형성수를 조사한 결과, 오배자면충의 간모 출현에 의한 충영(오배자)형성 시기는 6월 중순이었으며 간모는 미성숙된 입엽의 뒷면에 정착기생한 뒤 반대방향으로 융기하여 충영을 형성하였다. 오배자는 9월 중순부터 급격히 발육하였으며 면충의 밀도가 많음에 따라 오배자의 무게도 무거웠다. 붉나무에서 오배자면충의 충영 형성 부위는 정엽에서 가까울수록 많았으며 복엽상에서는 익엽이 95.8%를 차지하였다.
