Classification and Labelling system of Chemicals is a very important element for management of chemical safety. Classification and labelling system of Chemicals is very different among countries. This becomes a barrier for transportation of chemicals across counties. Recently, several international organizations (OECD,UNEP,ILO etc.) endeavor to harmonize classification and labelling of chemicals. In this study, we analyze classification and labelling system of chemical described in several regulations of our country, and examine acivities of IOMC(Inter-Organization Programme for the Sound Management of Chemicals)for harmonization of classification and labelling of chemicals. The Toxic Chemical Control Law, the Fire Services Law and the Industrial Safety and Health Law are the major regulation of management of chemical safety. Classification and labelling systems of chemical vary among several regulations. Particularly, labelling system of chemicals in transport vehicles are not appropriate in response to chemical accident. We suggest that task force team consisted with inter-administrative branches is needed to harmonize classification and labelling of chemicals, and recommend the introduction of UN number in labelling systems of chemicals in transport vehicles.

中等學校 學生들의 學校保健 敎育實態

박종식,박종안 순천향대학교 1993 논문집 Vol.16 No.3

도시와 농촌 학생들의 학교보건 교육에 관한 실태를 파악하기 위하여 연구자의 농촌소재 근무교와 근교에 있는 청주시내 중학교 3학년 학생을 대상으로 ① 건강에 대한 일반사항 ② 건강을 저해하는 요인 ③ 건강의 유지 증진 형태 ④ 건강의 이상유무 조치 등의 학교보건 실태조사를 실시한 결과 다음과 같이 요약된다. 1. 건강에 대한 일반사항으로 학생들은 평소 자신의 건강에 대해 상당히 관심이 있는 것으로 나타났고, 보건 교육은 도시 학생 전체의 39.6%와 농촌학생 전체의 47.8%가 TV나 신문, 잡지에서 배우고 특히, 농촌 학생의 경우는 26.5%가 학교에서 수업시간에 배운 것으로 학교 보건교육의 부족함이 나타나 대중매체에 중요함을 재인식하여 정선된 국민건강 교육 Program 개발에 최선을 다 할 것이며 위생관념은 농촌이 도시보다 2배이상 낮고 교실의 청결 및 환기 장치도 농촌이 좋지 않아 농촌학교의 각종 시설 및 처리장치 설치를 서둘러야겠다. 2. 건강을 저해하는 요인중 정신적 건강의 저해 요인의 경우 도시학생 61.2%와 농촌학생 46.1%가 진학과 성적문제이고, 특히 남학생보다 여학생이 더욱 높게 나타났다. 불규칙한 생활을 하는 학생도 도시 학생 50.3%, 농촌 학생 52.7%로 농촌 학생이 많으므로 학교교육을 정상화하고 학생들로 하여금 적성과 성적에 맞는 학과 및 진로를 스스로 결정 할 수 있도록 상담에 철저를 기하고 적절한 Sports, 건전한 여가 선용 등으로 심신을 건전하게 하여 건강장애의 예방과 치료에 최선을 다하여야 한다. 3. 농촌학생의 56.8%가 기본생화 습관중 불규직한 생활을 하는 것으로 나타나 도시 학생보다 농촌 학생의 기본 생활 습관 지도가 더욱 요구된다. 도시 학생 전체의 37.4%와 농촌 학생 전체의 45.8%가 충분한 휴식과 수면으로 건강을 유지한다고 했고, 하루에 운동을 하고 있는 시간은 농촌 학생 79.9% 도시 학생 83.9%가 30분 정도라고 했다. 건강의 필요성에 대해서는 도시 학생 38.0%는 피로를 쉽게 느끼기 때문이라고 답한 반면, 농촌 학생이 43.1%로는 아팠던 경험이 있기 때문이라고 반응을 나타내고 있다. 학생 건강증진 뿐 아니라 밝고 건전한 학교생활에 있어 전인적 인간 완성에 길잡이가 되므로 학교 당국은 학생의 여가, 정서활동에 보다 치밀한 계획과 교육이 요망된다. 4. 종합건강진단을 받는 이유로 도시 학생 전체의 10.7%와 농촌 학생의 전체 7.8%가 스스로 건강상태를 알아 보려고 했으며 , 학생들이 병적 증상 느꼈을때, 도시학생 2.0%와 농촌학생 1.2%가 양호교사와 상담한다고 반응을 보여 학교 보건 교육에 허술함을 나타내고 있다. 학생들은 병적 증상을 느끼면 20%정도는 "스스로 판단하여 약을 사먹는다".고 한다. 이것은 약품오용 또는 남용의 위험이 우려되고 있으며 약의 오 ·남용으로 부터 안전하게 보호될 수 있도록 보다 철저한 지도가 요구되고 법적인 제도 마련이 기습하다. 도시학교는 100%로 양호교사가 배치되어 있고 농촌학교는 全無한 것으로 나타난 바, 사회, 문화, 교통등 모든 면에서 불리한 농촌학교에 양호교사를 먼저 배치토록 하여 학생과 교사의 건강은 물론 지역사회의 보건 사업에도 이바지 할 수 있도록 하여야 하겠다. Researcher studied thd different aspects of school health education through thd third year students of the middle school in Cheong-ju city and a county. The results are as follows : 1. Generally, most of the students are much interested in thier own health, 39% of urban and 47.8% of rural students received healtheducation throuhg TV., newspapers, and magazine. Especically, 26.5% of rural students received the education ar school insufficiently. Therefore, we must recognize the importance of mass communication, develop and sipply standard health education program. 2. Among the factors interfering the general health, the mental health is important. Factors interfering mental health were problems of procceeding to a higher schol and school rcords in 61.2% of urban students and 46.1% of rural students. Therefore, we must normalize school education, conusel students to help them to decide their courses that are proper for their apptitudes and records, and do our best in proventing and abolishing health interfering factors through proper sports and leisures. 3. 56.8% of rural students have irregular basic living customs, so they need more health education than urban students. 37.4% of urban and 45.8% of rural students keep in enough rest and sleep. 83.9% of urban and 79.9% of rural students do exercise for half an hour a day. 30.0% of urban students think of neccessity of health when they were sick. 4. On the reason for health checking, 10.7% of urban and 7.8% students do this to know their own health condition. When they are sick, 2.0% of urban and 1.2% rural students counsel to nurse teachers. This means a lack of school health education. There is no school in the urban without nurse teachers, on the other hand, many schools in the rural are without nurse teachers. Therefore, first of all, education authorities must dispose nurse teachers in the rural school in order to contribute to community health and students health as well.

혈중납이 흰쥐의 Microsomal Cytochrome P-450 Monooxygenase 활성도에 미치는 영향

박기현,장성근,윤영안,김기웅,박종안 순천향대학교 1993 논문집 Vol.16 No.3

In rats treated with lead nitrate and/or red ginseng extract mixture we observed a change in the level of hepatic cytochrome P-450 and electron transport system for P-450 dependent reaction, and content of Zincprotoporphyrin(ZPP) and Hemoglobin(Hb) in whole blood. The content of cytochrome P-450 and ?? , and the activity of ECHEase, AHHase and NADPH-cytochrome C(p-450) reductase were slowly decreased according to the dosage of lead nitrate. On the other hand, the activity of ?? reductase was increased according to the dosage of lead nitrate, but in case of treatment with red ginseng mixture, this enzyme activity was slightly decreased. In whole blood, the content of hemoglobin and ZPP were not shown any critival change but lead content increased according to dosage of lead nitrate. These results suggest that content and activity of cytochrome P-450-dependent monoxygenase may be dependent on specificity of substrates, and the acute exposure of lead nitrate and red ginseng extract mixture was not affected any biological significance.

손부순,염윤기,이종화,장봉기,박종안 순천향대학교 기초과학연구소 1998 순천향자연과학연구 논문집 Vol.4 No.2

This study was conducted to estimate the water pollution load, water quantity and quality of inflow stream, status of water pollution and reduction of eutrophication in the Song-ak lake in Asan city. Inflow of branch to Song-ak lake has three streams, one is Eu-gok stream which has the most width of inflow area and another is Dong-hwa stream and the other is Ma-gok stream. The sampling numbers for water quality are 30 points from the sediment of bottom in the Song-ak lake from June, 1997 to ay, 1998. Water quality had been tested for water temperature, pH, dissolved oxygen(DO), chemical oxygen demand(COD), suspended solid(SS), total nitrogen(T-N), total phosphorus(T-P), colony numbers of E. coli, chlorophyll-α. The total nitrogen, total phosphorus and heavy metals(Fe, Pb, Cd) were analyzed by the migration test of the sediment. The results were as follows; The rate of water pollution by the livestock wastewater of the total water pollution load for BOD, SS, T-N and T-P were 59.8%, 82.9%, 56.1% and 90.6%, respectively. Mean daily inflow was 25,369m3. Quantity of inflow was highest at Eu-gok stream. The mean levels of pH, DO, COD, SS, T-N, and colony numbers of E. coli of the inflow water were 7.52, 10.25mg/ℓ, 2.12 mg/ℓ, 3.03 mg/ℓ, 2.25 mg/ℓ, 0.11 mg/ℓ and 1,795/100㎖, respectively. The worst inflow water quality was observed at Dong-hwa stream. The mean levels of pH, DO, COD, SS, T-N, T-P, T-N/T-P and colony numbers of E. coli at Song-ak lake were 8.06, 9.32mg/ℓ, 6.83 mg/ℓ, 4.78 mg/ℓ, 1.66 mg/ℓ, 0.115 mg/ℓ, 20.75 and 64/100㎖, respectively. these are higher than class IV by environmental water quality standards for lake. Mean level of trophic state index was 59.4. The mean levels of T-N, T-P, Fe and Pb by migration test of sediment at Song-ak lake were 259.7ppm, 10.546ppm, 1,704ppm and 8.54ppm, respectively. As the water pollution was mainly caused by livestock waste, the strategy for the reduction of eutrophication of the Song-ak lake should be concentrated on the control of the livestock waste.

低溫灰化法에 의한 중금속 분석

박종안 순천향대학교 1986 논문집 Vol.9 No.2

This research was conducted to investigate the optimal conditions of low temperature ashing apparatus, modified electric furnace, to solve the difficult problems frequently occurring in the analysis of heavy metals in various samples. The results were as follows: 1. Analyzed values of the samples pre-treated by low temperature ashing apparatus obtained more accurate results than those obtained by wet analytical method. The coefficient of variation of analyzed values were 2.7% by low temperature ashing method and 7.4% by wet analytical method. 2. The optimal electric power(W) was 200-300 and oxygen flow rate(ml/min) was about one-third of each maximum electric power in values. 3. Ashing time was shortest at the optimal conditions and it took longer with the increased amount of samples. 4. Low temperature ashing method gave better recovery yield rate for Cd, Cu, Pb or Zn than muffle furnace ashing method. Muffle furnace ashing method using high temperature of 550℃ gave the yield as low as below 50% for Zn, Pb or Cd. It was suggested that the latter be not adequate for analysis of Zn, Pb or Cd, in the samples.

장봉기,이종화,박종범,민준호,박종안 순천향대학교 기초과학연구소 1997 순천향자연과학연구 논문집 Vol.3 No.2

The object of this study is to survey water quality of reservoirsin in Asan city. We also suggest some countmeasures for environmental preservation toward sustainable urban development of Asan city. We analyze water qualities (pH, DO, COD, SS, T-P, T-N and Chlorophyll-a) of reservoirs. The level of water quality of small reservoirs is in the range of level Ⅳ-Ⅴ higher than the level Ⅲ established by the Ministry of Environment. Especially, water quality of Sinchang, Youngin and Shinchung reservoirs is worser than that of other reservoirs. Water quality of Asan and Sapkyo lake is the range of level Ⅳ-Ⅴ. As the levels of T-P and T-N are level Ⅳ and level Ⅴ, respectively, eutrophication might be progressed. Reservoirs in Asan city were already serious polluted by inflow of wastewater from residents, animal husbandries and industries. Recently, Metropolitan Area Development Planning(MADP) for Asan bay-area was suggested by the Ministry of Construction. According to this plan, industrialization and urbanization of Asan area will rapidly progress. If sewage and wastewater treatment facilitiesare not provided, water quality of reservoirs in Asan city will be worse. In order to prevent of environment pollution, first, the impact of industrialization and urbanization of Asan area on the environment should be considered at the beginning of MADP. Second, total effluent regulation of water pollution, air pollution and soil wastes, based on the self-purification of the Asan city environment, should be enforced.
