Fifty of 2nd year students of a high school in Gwang Ju, Chonnam were subjected to test of subjective fatigue syndrome and to test of objective fatigue syndrome Flicker Value during The period from Sep.1. 1980, to oct, 25, 1980, and following results were obtained. 1. The hightest frequency in each pnysical(A:41.0%) the next in mental(B:13.6%) and the lowest in sensory neurotic(C:35.0%) syndrome was obserbed in the group of 7 the period 2. The hightest frequency of subjective fatique syndrome was observed on the item of "feel tired on limbs" in group A (29.4%) and "feel thirst" in group C (23.0%) and "difficult to concentrate of thinking" in group B (7.0%) 3. In the period greatest Variation of F1icker Va1ue in the test of objective fatigue syndrome was observed aften 7tn period(3.7 cycle/sec) 4. In age group the Variation of Flicker Value was shown 2.9 (Cycle/sec) and the hightest frequency of subjective fatique syndrome was observed in the group of 16 years-ge. 5. In the distance of attending school the hightest frequency of Variation (3.8 Cycle/see) of Flicker Value and of subjective fatigue syndrome was observed in group "1Km" and the lowest was observed n group "5Km" 6. By the mean of thsir attending school the hightest frequency of Variation (3.6 Cycle/sec) of Flicker Value and of subjective fatigue syndrome was observed in the group Who go to school on foot. 7. By the time required in attending school the hightest frequency of Variation (3.7 Cycle/sec) of Flicker Value was observed in the group Who take "10 minutes" and the hightest frequency of subjective fatigue syndrome in the group Who take "20 minutes" Suggestion 1. The emotional rest of Students needs after physical traing. 2. The physical education must be considered not to be practiced after lunch 3. The time required and the means of attending school of the students Who go to school in a short distance must be observed more carefully.

대학실험실 안전관리 현황 및 안전사고 분석을 통한 예방 효과 제고
강주혁 인천대학교 공학대학원 2022 국내석사
본 연구에서는 서울 소재 OO대학의 2016년부터 2020년의 실험실 사고사례 192건을 전수 분석하여 연구 실험 등에 의한 사고의 유형을 일반화하고 전반적인 안전 사고 발생의 경향성을 도출하였다. 또한, 분석 결과와 실험실 안전사고에 대응한 기존의 정책 방향을 비교하여 안전 사고 예방 조치의 적정성을 판단하고자 하였다. 현재까지 실험실 안전관리는 실험실 안전관리 정책에 따른 일정한 분류 기준과 가이드라인에 의하여 일괄적으로 수행되었지만, 본 연구와 같이 실험실 안전사고 분석 결과에 기반한 귀납적인 정책 수립이 가능할 것으로 판단된다. 나아가, 실험실 사고 특징을 고려한 세분화된 실험실 안전사고 관리 방안을 수립한다면 실험실 사고예방에 기여할 수 있을 것으로 생각한다. 지난 5년 동안의 국내 최대 연구 대학의 연구실 안전사고 192건을 유형화하여 분석한 결과, 중점 관리 부문을 도출하였으며, 주요한 사고 예방 활동을 분석한 결과 다음과 같은 정책 개선 방향을 제안할 수 있었다. 다양한 연구 활동 분야 중 화학분야의 “안전수칙 미준수와 누출”, 그리고 “취급부주의에 의한 접촉사고”, “화학 실험에 의한 누출사고와 이에 의한 화상 사고”가 중점 관리해야 할 실험실 사고 유형으로 나타났다. 따라서, 본 유형에 속하는 연구실의 책임자는 「연구실 사전유해인자위험분석 실시에 관한 지침」에 따라 연구실 안전현황 분석, 연구개발 활동별 유해인자 위험분석, 연구실 안전계획, 비상조치계획 등을 수립하여 연구 활동 종사자들이 충분히 인지 할 수 있도록 조치하여야 할 것이다. 또한, 모든 연구실의 연구 활동 종사자를 대상으로 한 교육 프로그램을 전공, 실험 유형 등에 따라 다양화하고, 특히 화학실험의 안전수칙, 취급방법, 누출 등과 관련된 교육을 중심으로 유사 계열의 연구실 사고 예방 교육을 증대하여 사고 발생을 억제해야 할 것이다. 마지막으로, 연구실 정기 점검을 통해 연구실의 모든 유해인자와 위험요소의 분석 및 평가를 실시하고, 연구 시설에 대한 결함 유무를 점검 후 그 결과에 따라 연구실 등급을 부여하고 등급별 개선조치 사항을 이행하여야 할 것이다. 이번 연구는 대학 연구실에서 발생된 안전사고의 결과를 분석하여 대학에서 실시하고 있는 연구실 안전관리 제도와 안전사고 예방 효과를 실증적으로 검증한 의의가 있었다. 더불어, 주기적인 결과 보고와 정보 공유를 위한 내부 활동 강화의 필요성을 확인한 계기가 되었다. In this study, 192 accident cases from 2016 to 2020 in university laboratory were completely investigated to generalize the types of accidents caused by research experiments and derive the overall tendency of occurrence of safety accidents. In addition, the analysis results were compared with the existing policy directions with a view to judging the appropriateness of accident-prevention measures in lab. Laboratory safety management has been performed uniformly according to certain classification standards and guidelines based on laboratory safety management policies so far, but it can be possible to reestablish more effective policies based on the results of analysis of laboratory safety accidents. Furthermore, if subdivided safety accident management plans considering the characteristics of laboratory accidents are established, it can greatly contribute to the prevention of laboratory accidents. By analyzing laboratory accidents of the largest research university in Seoul, the types of priority management were derived, and major accident prevention activities were analyzed so that following policy improvement directions could be proposed. Among the fields of research activities, “non-compliance with safety rules and leakage”, “contact injury due to careless handling”, and “leakage accident due to chemical experiments and burn accidents” in the chemical field were identified as the types of laboratory accidents that must be intensively managed. Therefore, the persons responsible for these types of laboratories should carry out the analysis of the present condition of laboratory, the analysis of the risk of harmful factors by research activities. Moreover, they should establish laboratory safety plans, emergency action plans according to the 「Guidelines Regarding the Implementation of Prior Analysis of the Risk of Harmful Factors of Laboratories 」and make sure that those who engage in research activities sufficiently recognize these plans. Education programs for those who engage in research activities should be diversified according to their majors and experiments types. In particular, education on the prevention of accidents in similar laboratories should be expanded to suppress the occurrence of accidents by focusing on education related to safety rules, handling methods, and leakage of chemical experiments. Finally, all harmful factors and risk elements of laboratories should be analyzed and evaluated through regular inspections of laboratories. And research facilities should be inspected to see if there are any defects to assign laboratory safety grades so that improvement measures by grade should be taken. This study was meaningful in that it analyzed the results of accidents that occurred in university laboratories to verify the safety management systems being implemented by universities. The result of this study shows that periodic reporting of results and strengthening internal activities for information sharing are essentially needed to prevent accidents in university.
