  • This study carried out the investigation about the actual conditions of the management, disaster analysis and safety awareness on excavator in one of construction equipment and tried to make it's preventive measures. To achieve this, first of all, the accident of the internal Construction Industry process Investigation and Analysis, and then analyze an cause of accident based on it. Next, For the conditions of safety management conduct a survey to Investigation and Analysis and Propose preventive measures. The results of this study can be summarized as follows. 1st, Status of safety awareness and management of construction equipment tend to seek quickly and easily for the interests of sight. 2nd, Half the precincts of the equipment is causing major disaster. 3rd, The risk of excavator operation's indicators and drivers is so much potential. 4th, The preventive measures are needed for strengthening safety education, professional legal education, changes in safety awareness, the development of prevention system.

  • 떡은 수분활성도, pH, 보관온도 등이 미생물 증식에 적합하고 구입 후 별도 조리과정 없이 그대로 섭취하는 식품으로 미생물학적 안전문제를 자주 야기하고 있다. 본 연구는 국내 유통 떡에 문제시되는 미생물학적 위해요인을 제조공정별로 파악하고 그 위생관리 개선방안을 도출하고자 하였다. 3가지 떡 (시루떡, 가래떡, 경단)을 선정하여 원료, 제조공정 및 제조환경에 대한 미생물 오염도 분석을 실시하였다. 8가지 원재료의 오염도 분석결과 일반세균 2.5~4.5, 대장균군 ND~1.9, 진균수 1.2~2.1, B. cereus 1.0~2.1 log CFU/g수준으로 검출되었으며 E. coli, S. aureus, C. perfringens는 검출되지 않았다. 떡의 제조공정별 오염도 분석결과 원료의 불림 분쇄 공정에서 일반세균, 대장균군, 진균, B. cereus의 오염도가 증가하나 증자 후 감소하여 완제품에서 일반세균은 2.2~3.7, 대장균군 ND~1.8 log CFU/g 수준으로 나타났다. 제조환경의 미생물학적 오염도 분석결과 전처리실의 쌀분쇄기, 냉각수조, 펀칭기 등의 설비에서 오염수준이 높게 나타났으며, 전처리실 작업자의 개인 위생이 미흡한 것으로 나타났다. 작업장 공기 오염도 분석결과 청결구역 3곳에서 일반세균 34~46, 대장균군 2.5~7.0, 진균수 14~30 $CFU/plate{\cdot}5min$ 검출되어 권장 낙하세균기준을 초과하는 것으로 나타났다. 본 연구결과 떡의 원재료 및 완제품의 미생물학적 오염수준은 안전하나 제조환경의 오염도는 문제시되는 것으로 나타나 제품의 교차오염 가능성을 내포하고 있는 것으로 사료된다. 따라서 제조 설비 및 표면시설에 대한 체계적인 세척 및 소독을 실시하여 미생물학적 위해를 감소하고 작업자 위생 관리 교육 프로그램을 선행하여 작업자 개인의 위생 수준 향상, 작업장 내 공기중의 미생물 관리가 함께 이루어지도록 하는 것이 필요한 것으로 여겨진다.

  • The purpose of this thesis is to provide the framework of the health education curriculum on a school level which should be accomplishe in futrue and farthermore to establish the health education as a independent and regular course. The relation among the status in quo and the satisfaction degree of health education, the degree of the knowledge about health, the degree of the understanding of the health education and the degree of requirement for the health education curriculum has been analyzed in this paper. The research has been carried out through the questionnaire forms distributed to the girl students and the instructors at a few general senior high school and vocational senior high schools in Seoul, and the consequences are as follows : 1. As to the degree of understanding of the health education, it has been indicated that the health education should be performed one or two hours a week from the elementary school for all the boy and girl students by the experts trained in the departments concerned with health. 2. Concerning the degree of requirement for health education curriculum, the high school girl students have shown the need for first aid, sex education, environmental health, drinking, smoking, drug abuse, maternal and child health, industrial health, safety health, mental health, growth & development, epidemiology, the old health in the order named. On the other hand, the instructors have shown the need for drinking, smoking, drug abuse, sex education, maternal and child health, public health and industrial health also in the order named. The items having low degree of requirement are biostatistics, community health and health administration in case of the gril students and biostatistics, health administration and health economics in case of the instructors. 3. The status in quo and the satisfaction degree of the health education has proved higher in senior high school curriculums than in junior high school curriculums, and the most instructive course about health has turned out to be gymnastics in junior high school and the training course in senior high school respectively. 4. As to the degree of understanding of the health education in case of the girl students, the significance has been found between the health condition and the time for performing the health education, the monthly income and the objects for the health education, and the school records and the school hours per week. The significance has been shown only in regard to the school records in case of the degree of requriement for the health education curriculum. 5. The degree of requirement for the health education in case of the instructors has shown the significance between the teching career and the need for the health education. In addition, the degree of requirement for the health education curriculum has indicated significance with regard to sex and age. 6. The degress of the understanding of the health education according to the degree of knowledge about health and the degree of requirement for the health educatio curriculum have been all turned out to be statistically significant. 8. Among the factors which have an influence on the degree of the understanding of the health education, the recognition of the relation between the health course and the training course has significatly influenced the selection of the health education instructors. In additon, the understanding of the need for the health eduation has significantly influenced the objects for the instructors and the school hours, and the understanding of the need for establishing the health education course has significatly influenced the time for performing the health education.
