Objectives : To evaluate the health hazards in the underground storage facilities of ginger roots. Methods : The authors reviewed the emergency rescue records from the Seosan fire department over the period Jan 1, 1996 to Aug 31, 1999. The atmospheres in 3 different underground storage locations were analyzed for $O_2,\;CO_2,\;CO,\;H_2S\;and\;NH_4$. Results : From the emergency records, we were able to identify 20 individuals that had been exposed to occupational hazards in the underground storage facilities. Among these 20 cases, 13 were due to asphyxiation (resulting in f deaths) and 7 were due to falls. In the first atmospheric tests, peformed on Feb 25, 1998, the O2 level inside the underground storage facility, located about $5{\sim}6$ meters below the surface, was 20.6% and the $CO_2$ level was about 1,000 ppm. CO, $H_2S\;and\;NH_4$ were not detected. In the second tests on Jul 6, 1999, measurements of the $O_2$ level at 3 meters below the surface in two different storage locations were 15.3 and 15.1%. And the $O_2$ levels inside the storage facilities were 12.2 and 12.1%. The $CO_2$ level was above 5,000 ppm (beyond upper limits of measurement). CO, $H_2S\;and\;NH_4$ were not detected. Conclusions : We conclude that asphyxiation in the underground storage facilities for ginger roots was not due to the presence of toxic gases such as CO, $H_2S\;and\;NH_4$, but rather the exclusion of oxygen by carbon dioxide was responsible for causing casualties. For the development of a hazard free working environment, safety education as well as improvements in storage methods are needed.

Objectives : To assess the availability of the glycophorin A (GPA) assay to detect the biological effect of ionizing radiation in workers exposed to low-doses of radiation. Methods : Information on confounding factors, such as age and cigarette smoking was obtained on 144 nuclear power plant workers and 32 hospital workers, by a self-administered questionnaire. Information on physical exposure levels was obtained from the registries of radiation exposure monitoring and control at each facility. The GPA mutant assay was performed using the BR6 method with modification by using a FACScan flow cytometer. Results : As confounders, age and cigarette smoking habits showed increasing trends with GPA variants, but these were of no statistical significance. Hospital workers showed a higher frequency of the GPA variant than nuclear power plant workers in terms of the NO variant. Significant dose-response relationships were obtained from in simple and multiple linear regression models. The slope of the regression equation for nuclear power plant workers was much smaller than that of hospital workers. These findings suggest that there may be apparent dose-rate effects. Conclusion : In population exposed to chronic low-dose radiation, the GPA assay has a potential to be used as an effective biologic marker for assessing the bone marrow cumulative exposure dose.

현대사회는 급격한 경제사회의 변화와 향락적 풍조, 가치관의 혼란 등 정신적 변화와 도덕성이 결여된 과학기술의 발달로 각종 사회병리현상과 우리생활의 안전을 위협하는 범죄는 갈수록 증가하고 있다. 또한, 공공경찰이 치안서비스를 효과적으로 공급하는데 있어서 한계에 직면하고 있는 상태에서 수익자 부담 원칙에 의한 민간경비제도를 도입하여 개인 및 집단의 안전과 보호를 위해 노력해왔으며, 각종 국제행사를 치르면서 민간경비산업은 첨단장비 및 기술을 활용한 복합적인 형태로 발전하였다. 그러나 우리나라 민간경비산업은 사회의 팽창과 더불어 국가의 공공분야 서비스 영역이 점차 확대됨에 따라 민간경비의 영역도 빠르게 확대되어가고 있으나 질적 향상은 이를 따르지 못하고 있는 것이 현실이며, 질적 향상의 근간이라고 할 수 있는 민간경비의 신임 교육에 대한 연구는 공공의 치안을 담당하고 있는 경찰, 군인 등의 교육연구에 비하여 미비한 실정이다. 따라서 본 연구에서는 민간경비원 중 비중이 가장 높은 기계경비와 시설경비 종사자의 신임 교육을 중심으로 업무현장에서 필요한 교과목과 필요성이 떨어지는 교과목 및 조사대상자의 특성에 따른 각 교과목의 활용성 차이를 분석하여 민간경비원의 신임 교육 발전에 기여하고자 한다.

Objectives : This study aims to analyze the tasks, recognition and obstacles in operation of school dental clinics and to examine opinions on installation, operation and prerequisites for toothbrushing facilities. Methods : It conducted a survey t o the persons in charge at 378 school dental clinics in Korea and total 127 sheets, excluding incompletely answered data, were used for analysis by using SPSS 18.0. Results : Two regular dental hygienists visit school dental clinics 2-3 times per week and work 4-6 hours per week on average. Their tasks include oral health education, toothbrushing instruction, oral examination, sending school newsletters, and dental sealants. The obstacles of operation include excessive workload other than the work for the school dental clinic, lack of dentists, and lack of cooperation of principals and teachers in school. The persons in charge think that the chief task of the school dental clinic is the continuous oral health management, and it effectively affects students' oral health improvement. Most of them were for the installation of toothbrushing facilities. They said that it will be effective in students having an adequate toothbrushing habit and their toothbrushing rate increasing higher. They thought that if the school dental clinic is changed to toothbrushing facilities, it will improve students' oral health management. The prerequisites for toothbrushing facilities are the support of manpower in charge, principal's support, and development of operational programs. Conclusions : The most effective function of school dental clinics is constant oral health management. However, when public health doctors are reduced and dental sealants get included in health insurance, the budget of local government will decrease and then it will eventually reduce the work of school dental clinics. Therefore, it is needed to enhance support for school dental clinics or install a toothbrushing facilities rather than a school dental clinic.

Children's play facilities have changed over a decade from the traditional play facilities in the front yard to the new type of commercial play facilities which install more exciting and enjoyable facilities, such as Kids Park. The more diversified in the type of facilities, the more difficult in the safety management by the existing system. The 'Safety Management System of Children's Play Facilities' of MOSPA(Ministry of Security and Public Administration) has provided the safety information uni-directly by government sector to the private communities. Recently, multi-directional information sharing methods, such as community mapping are adopted actively in the social activities which have common purpose for making the better community by information sharing with government and private sector. On the purpose of citizen's participation for safe play facilities and preventing accidents, this study investigated the status of child accidents and safety standards, especially focused on the children's play facilities. And the way for sharing safety information among the communities with the GIS mapping skills is suggested in the respect of more easily monitoring and practically inputting the comments on the status of management of play facilities by real users based on their experiences. It is expected that more activities from the private sector would participate to the safety management of children's play facilities by realizing the suggested system.

본 연구는 창원시 도시지역을 대상으로 도시공간을 고려한 야간시간대의 도시열섬특성을 파악하기 위해 1:1,000 축척의 토지이용도 및 토지피복도와 DTM, 그리고 ASTER 위성영상에서 추출된 야간시간대의 지표온도자료를 활용하였다. 분석결과에 따르면, 야간시간대는 건물이 밀집되어있는 단독주거지역이 상업지역이나 공공시설지역보다 열섬강도가 높았고, 이것은 에너지소비에 의한 인공열 방출이 열섬형성에 많은 영향을 미치기 때문으로 판단된다. 또한 이러한 점 때문에 공업지역에서는 건물은 가동시간에 따라 온도차이가 매우 크게 나타났다. 한편, 도시녹지지역과 하천지역은 도시열섬을 완화하는 냉각효과가 있는 것으로 확인되었으며, 열섬강도가 높은 지역에 녹지 및 수변공간의 조성으로 열섬강도를 낮출 필요가 있을 것으로 판단된다. 이상과 같은 결과는 야간시간대의 도시열섬을 완화하는데 있어 개발계획 수립시 효율적인 공간활용을 위해 기초자료로 이용될 것으로 사료된다.

The purpose of this study was to propose HACCP system implementation properly and to secure the food safety of school foodservices in Pohang city since the proper facilities and equipment should be key factors in food safety and production. So this study was designed to evaluate existing equipment in food production area, receiving and dining area, and employee facilities. Questionnaire was mailed to 107 school foodservice dietitians in Pohang area and 97 were responded (90.7% response rate). Approximately sixty percent of foodservices were not available separate receiving or polluted area, fifty one percent were installed screen door for insecticidal and temperature and humidity control, and these environmental conditions were hard to keep kitchen dry and sanitary condition. Usually public schools were better equipped than private schools. Forty three percent of school foodservice had initial use of non-foodservice, opened before 1994, and thirty three percent of elementary school foodservice. Among employee facilities, hand washing sanitation stand was prepared seventy nine percent (78.9%) of school foodservices. Dietitians chose outworn equipment and facilities (30.9%), difficulties of maintaining standard temperature and humidity for foodservice (20.6%), lacking separate receiving or polluted area (13.4%), indirect contamination of water hoss (10.3%), and lacking employee facilities (10.3%) as critical points to correct in school foodservice. Therefore governmental regulating agencies must review and approval of plans prior to new construction or extensive remodeling of school foodservice facilities. In addition to these requirement, plan must be set-up step by step to implement HACCP system properly.
