The incidence of Sexually Transmitted Disease has risen despite the progress in its diagnosis and treatment methods. For the effective control programs of S.T.D it should be required medical and social approaches. This survey was conducted in Young Dung Po and Sung Buk areas from June, 1986 to September, 1986. The 1185 prostitutes were studies in order to determine the prevalences of sexually transmitted disease. The results were as follows: 1. The average age of prostitutes was $24.0\pm3.9$ years. The age group of 21-25 years old was the highest level of about $70.3\%$. 2. The positive rate on non Gonococcal urethites was $9.1\%$ at Sung Buk area and $15.3\%$ at Young Dung Po area. 3. The positive rate of Neisseria Gonorrhoeae on culture of TM media was $6.4\%$ or total level and incidence ratio of Neisseria Gonorrhoeae: Non Gonococcal urethritis was 1: 1.7. 4. The positive rate of PPNG was occupied about $26.3\%$ among the total NG positive case. 5. The positive rate of VDRL Slide Test was $2.9\%$, and antibody Titer level of 1:2 was $38.8\%$. it was the highest of all Titer distribution.

The survey was conducted on the actual conditions of species, the facilities, a establishment of regulation concerning laboratory animals and the related problems on users and suppliers of laboratory animals in Korea. The questionnaires were sent to 430 and received from 107$(24.9\%)$ places. The results obtained were as follows : 1. Experimental animals used at the 107 places were 21 species: mouse(90\;places,\;84.1\%)$, rat $(61,\;57.0\%)$, rabbit$(76,\;71.0\%)$, guineapig$(42,\; 39.3\%)$ etc. 2. The main organizations using laboratory animals were university $46(43.0\%)$, institute $32(29.9\%)$ and pharmaceutical company $27(25.2\%)$ etc. 3. Most the laboratory animal facilities in Korea have been conventional system without environmental controls, but a few places have been recently established barrier system. 4. To get a good experimental result, a regular genetic and microbiological monitoring of laboratory animals should be done. 5. It was required that a educational facilities and a quality test agency for laboratory animals should be established. 6. It was also required that a regulation for breeding and using of laboratory animals should 'be enacted.

본 연구는 충남지역 전체 행정 구역인 14개 시 군에 소재하는 초 중 고 급식학교를 골고루 포함시켜 305교를 편의 추출하고 각 학교에 근무하는 조리원 1명씩을 무작위 추출해 총 305명의 조리원을 대상으로 자기기입식에 의한 설문조사를 실시하였다. 본 연구는 학교급식 조리원의 학교급식 관련 위생지식 및 학교급식위생관리지침서 3차 개정에 준한 HACCP 수행도를 조사해 학교급식 위생수준 향상을 위한 기초자료로 제공하는 데에 목적을 두었다. 연구 결과 조리원의 학교급식 관련 위생지식 수준이 높을 때 HACCP 수행도가 높아 조리원의 위생지식 수준이 HACCP 수행도에 중요한 영향을 미치는 요인으로 파악되었다. 그러나 초 중 고 중에서 초등학교로 갈수록 조리원의 위생지식 수준은 높으나 초등학교에서 일부 항목의 HACCP 수행도가 낮았는데, 이는 본 연구 대상 초등학교가 중학교와 고등학교에 비해 면단위 농촌형 소규모 학교가 많아 HACCP 수행에 필요한 인력과 시설 설비 기구를 적정하게 보유하지 못하고 있기 때문으로 여겨진다. 따라서 소규모 학교에 대한 인적 물적 자원의 지원이 이루어질 필요가 있었다. 그리고 고등학교에서 조리원의 HACCP 수행도가 낮은 것은 이들의 HACCP 위생교육 횟수 부족에 따른 위생지식 수준이 낮은 점과 관련이 있으므로, 고등학교 조리원에게 1일 3식의 과다한 업무 속에서 짧은 시간 내에 취약 항목인 조리 전후 식재료나 음식의 취급 및 보관 등에 관한 위생교육을 자주 실시할 수 있도록 돕는 교육자료를 개발해 제공할 필요가 있었다. 중학교의 경우 조리원의 위생지식 수준과 HACCP 수행도가 높으며 학교급식 HACCP 관련 시설 설비 기구를 잘 갖추고 있어서 양호하였다. 그러나 본 연구는 충남지역 초 중 고에 근무하는 조리원을 대상으로 조사한 결과이어서 표집이 제한되어 있으므로, 연구 결과를 일반화하기에는 제한점을 가지고 있다. 앞으로 학교급식에서 지속적으로 문제가 되고 있는 위생관리에 관한 현장연구가 활발히 이루어지고 이 결과를 반영한 위생교육이 활성화됨으로써 학교급식 조리원의 위생지식 수준과 현장실천도를 높여 학교급식 품질을 향샹시켜 나가야 할 것으로 생각된다.

Rapid economic development and increase of energy consumption in east Asia including China, Korea and Japan has arisen a concern in air pollution problems in local and regional scale. Specially, China is accomplishing a success in continuous economic growth, while increasing energy consumption has caused a load to air quality because major energy source is coal which is relatively unfavorable in terms of air pollution. In this article, discussions have been given with the purpose of gaining some insight into the situation of air pollutant sources, air quality in China and transboundary transport of air pollutants in this area. Very limited information has caused insufficient survey, however, regional cooperation in environmental conservation may hopefully improve the air quality in this area.

A survey on the school foodservice was conducted from 693 middle school students to examine their degree of satisfaction on foodservice with the object to enhance the quality of school foodservice in Gwangiu and Chonnam area. The degree of satisfaction with school foodservice ranked high in taste, temperature and service categories. There were notable differences in the satisfaction level by the gender of the students. Male students ranked higher than female students in taste, temperature and the sanitary condition of food containers. According to grades, first grade students ranked the highest in satisfaction of food selection, temperature, services and cafeteria. Regarding the amount of left-overs, soup and pot-stew were the greatest followed by side dishes. Reasons for leftover food were listed as being tasteless, having no appetite, or large serving size.

It has been referred as a problem that heat source/sink is distance from heat demand area in using unused energy. To solve the distance problem in using unused energy, the water from city water system like tap water, rain water, waste water used as unused energy. To survey the potential of the water of city water system, it is developed that the calculation method of the potential using unit method. The amount of theoretical unused energy and energy saving in the Osaka City, Japan were estimated by using that method.

Indoor carbon monoxide (CO) concentration and personal CO exposures were measured Asan where CO poisoning from twenty coal usage briquette as a domestic fuel to cook and space heating. Twenty-five were houses selected from the Asan area for the survey conducted in February 1997. Newly developed passive CO samplers were placed in the kitchen and living room for the indoor concentration measurement and were worn by homemakers for personal exposure monitoring. The daily average of indoor CO concentration was 16ppm in the kitchen and 10ppm in the living room. The indoor concentration and personal exposures to CO were different in types of the space heating system. House ventilating methods and socioeconomic conditions were also important factors in determining the indoor and personal CO level in Asan.

Flora and standing crops of the periphyton communities were examined at five sites in the mountainous streams of the Dam of Peace, Korea, from June to November 2003. The attached algal communities comprised totally 76 taxa belong to the 5 classes. In species composition, diatoms and green algae overwhelmingly dominated the periphyton communities although their standing crops were low. During the survey period, major dominant species were Navicula gregaria and Nav. pupla var. capitata, as 11.7% and 8.9% of total standing crop, respectively. Other subdominant species were Scenedesmus ecornis and Spirogyra weberii in green algae, Cymbella affinis, Cymbella minuta. Fragilaria capucina, Melosira varians, Naw. cryptocephala, Nav. exigua var. capitata, Nav. gregaria, Nit. sublineuris in diatom. In the seasonal appearances, S. ecornis and Oscillatoria nigra were occurred in summer, C. affinis and F. capucina in autumn, and N. sublinearis, and species Spirogyra weberii in winter, respectively.

The concentration of ozone in 5 major cities in Korea( Seoul, Pusan, Taegu, Kwangjoo, Incheon ) has been shown increasing trend after 1984, while decreasing trend in Hsan. According to the data from 12 monitoring stations in 9 cities of metropolitan area from January 1994 to August 1994, ozone concentration exceeded short term standard 99 times and 87%(861imes) of those was occurred during July and Augusta while the maximum ozone concentration was appeared mainly between 14: 00 and 17: 00 daily. As the result of epidemiological survey, main substances which irritate eyes were identified to be PAN and formaldehyde rather than ozone while ozone was identified to be reachable to deep part of respiratory system main target organ of ozone.
