  • 본 연구는 PC방의 세균 오염 실태를 조사하기 위한 목적으로 2004년 7월${\~}$12월까지 서울시내에 있는 PC방(Internet Cafe)들 중에서 34곳을 표본으로 선정하여 연구를 수행하였다. 총 세균수를 측정한 결과, 키보드에서는 $9.0{\times}10^4$ CFU/ml, 마우스에서는 $2{\times}10$ CFU/ml, 그리고 화장실 손잡이에서는 $5{\times}10^3$ CFU/ml의 세균이 검출되었다. 이는 화장실 손잡이보다 키보드와 마우스에서 세균에 대한 오염정도가 더 심한 것을 의미한다. PC방에서 항생제에 대한 내성을 지닌 7개의 균주를 분리해 내었는데, 2개의 균주는 methicillin과 erythromycin에 대한 내성을 나타내었고, 5개의 균주는 gentamicin, ampicllin, cefotaxim, chloramphenicol에 대해서 내성을 나타내었다. 이들 균주들을 동정한 결과, 2 균주는 Staphylococcus aureus로 동정되었고, 4 균주는 Actinobacillus ureae로 동정되었으며. 나머지 1개의 균주는 Pasteurella multocida로 동정되었다. Pasteurella multocida와 Actinobacillus ureae는 잠재적인 병원균으로 이전에 Pasteurella ureae로 알려졌던 Actinobacillus ureae는 인간의 상부 호흡기에 드물게 공생하는 것으로 알려졌으며, Pasteurella multocida는 많은 가축의 비인두강 안에 존재하는 평범한 정상 균총을 구성하는 세균인 것으로 알려졌다. 항생제 내성에 대한 연구 결과 Staphylococcus aureus는 erythromycin과 methicillin의 혼합제에 대해서 $100\;{\mu}g/ml$ 이상의 높은 항생제 내성을 나타내었고, Pasteurella multocida와 Actinobacillus ureae는 gentamicin, ampicillin 에 대하여 $100\;{\mu}g/ml$ 이상의 높은 항생제 내성이 있음을 알 수 있었다.

  • This study was carried out to investigate the current state of occupational health management and characteristics of employees working in small-scale-enterprises (SSE) employing less than 50 workers. Samples were chosen among the two thousands employees working in 838 factories where located in Youngdungpo-Ku, Seoul, Korea. The study results were as followed: 1. Most factories investigated in the study were manufactures (68.6%) which were established in 5 to 10 years ago (29.2%), employing less than 5 workers (72.9%) and registered in accident compensation insurance (23.0%). 2. Health screening was undertaken in 24.9% workplaces for periodic health examination and in 1.5% for special health examination. Environmental monitoring was done in 3.3% factories. Very few factories displayed Material Substance Data Sheet (MSDS) in 3.1% among the total factories. 3. Workplaces usually had their own toilets in 75.9% and washing basin in 58.6% as types of sociowelfare facilities. 4. Employees responded in the study were mostly in the range of age from 30 to 39 in 34.7%. male in 84.8%. the married in 70.3%. manual workers in 42.0%. mostly working regularly 51 hours per a week in 48.2% and earned 710.000 Won to 1.000.000 Won per month in 35.0%. Medical utilization for employees were covered by factories sponsored medical insurance in 12.7% and by provincial sponsored medical insurance in 83.4%. 5. Two point six percents of employees were suffered by diseases. The health complaints indicated were mainly digestive problems in 46.7% and hypertension in 24.4%. 6. Employees wore personal protective equipments for work such as gloves in 48.1%. safety shoes in 30.5%. ear plug in 5.5% and mask in 6.9%. Based on the results of study, we recommend that various types of occupational health management should be developed according to workplace working condition of each factory. In addition to the development of occupational health strategies. we think that it is more important to monitor and to allocate how effectively they operate each other on the basis of longitudinal continuity. Besides, we would like to insist that these all management effort should be focused on prevention of disease and occupational health education of employees.

  • This study was carried out to investigate the changes of rural residential environmemts accompanied by the rural village improvement projects. The results of this study can be a guidoline for further betterment works of rural village envirnments. This sutdy is composed of the survey of two major parts, one Is the interview of the residents and the survey of existing conditions of residential environments, and the other is a questionnaire survey of the mental image, preference and satisfaction for each village residential environments. Based on preliminary investigation, five rural villages, located In Kyungsamgun., Kyungbuk province, were selected as sutdy sites. The major results are summarized as follows; 1. In socio-cultural enveronments, the ratio of compound and non - agricultural household are increased with the modernization of rural villages. On the ocher hand, the numbers of neighbor's association are considerably decreased. This means the traditional community of korean rural villages are diminishing. 2. In physical environments, the ratio of improved western type gouses are increased In modprnized villages. And the modernization is most remarkable in the palls of fences and gardens. 3. By the result of the analysis of residfnt's environmental image and preference, the image scores of urban, formal, mdoern, etc. are showed to be high. And the preference is also high in modernized villages. But in general, the Preference for the village environment is comparatively low in all villages. This means the improvememt work should be continuous and systematic. 4. By the result of stepwise regression analysis, the variables, affecting the preference of village environment. are regularity, familiarity, amount of greenery, beauty of surrounding scenery, convenience, cleanness, etc. The R2s of the perference models were 0.4486 ∼0.9395, Which are considered to be high. 5. In the satisfaction for each residences, the toilets are mostly dis - satisfying. With the modernization of vilelages, the needs for environmental quality by residents are increased. 6. In the satisfaction for village enveironments, the satisfaction level is most low in service facilities, such as public bath, barbershop. And the satisfaction for the scenic beauty, the amenity of surrondings, and the com munity of the traditional villages, are commparatively high in conventional villges. 7. The imporvement works, based on the characteristics of each rural villages, are recommended. And the tradition of Jung - ja tree spaces and harmony with surrounding landscape of traditional villages, must be conserved with good regards.

  • To verify welfare needs, rural health and environmental factors were compared between agricultural and nonagricultural groups over the past 10 years. Based on a survey of rural life by the Rural Development Administration, whose sample included agricultural (72.8%) and nonagricultural (27.2%) groups, all factors were analyzed using SAS ( 9.3). For rural home heating, the use of oil boilers (77.2%-78.0%) decreased (53.0%-53.7%) over the same period, whereas that of electric boilers increased (21.9% and 13.5% for agricultural and nonagricultural groups, respectively). The joint water- supply increased, and the use of flush toilets (52.4% to 84.5% in the agricultural group and 64.6% to 81.4% in the nonagricultural group) and hot-water bathing was higher in the agricultural group (79% to 92.6%) than in the nonagricultural group (72.2% to 87.6%) at the p<0.001 level. Incineration accounted for the largest portion of household waste until 2006, when it was replaced by other treatment methods such as the pay-per-treatment option (44.4% and 68.3% in the agricultural and nonagricultural groups, respectively) (p<0.001). Garbage disposal in 2001 was mainly burial or animal feed, but separate collection increased in 2010 (42.2% and 64.3% in the agricultural and nonagricultural groups, respectively) (p<0.001). The self-perception of health was lower in the agricultural group than in the nonagricultural group (2.96 to 2.74 on a five-point scale in the agricultural group and 3.07 to 2.98 in the nonagricultural group). Drinking decreased less in the agricultural group (criteria: one point once a week,; 1.48 to 1.20) than in the nonagricultural group (1.13 to 0.80) at p<0.001, and a similar pattern was found for smoking (p<0.001). Health screening decreased in the last 10 years (scoring based one point/1-2 times per year,: 0.94 to 0.64 in the agricultural group and 1.08 to 0.69 in the nonagricultural group;p<0.01). These results indicate that various health and environmental factors were less favorable to farmers except for bathing in comparison to nonagricultural living in the same area. This suggests that people in agriculture are less likely to live and work in favorable environments than those outside the sector and thus indicates a need for more attention to the national health welfare system for farmers for systematic realization.

  • This study was performed to estimate the daily water consumption for watering livestock and home use, and to organize the water systems in the rural districts of Korea. For these purposes, 560 farms and other 40 urban families were randomly chosen and investigated about their water systems and daily water consumption seasonally from July 20 to August 31, 1973, and other 82 livestock raisers' useful data for watering livestock helped the study to assess the consumption of livestock water and compare it to that of general farms which bred some domestic animals as their sidelines. The results of data showed that the daily consumption of water was varied with the difference of districts and seasons in which the investigations were conducted. The results were summarized as follows. 1. The mean consumption of water for home use was varied with the range of 30.2-48.7 lit./day in summer and 22.4-45.2 lit./day per a person, respectively, in the rural districts, which showed that the water consumption in summer was more than in autumn. 2. The mean consumption of livestock water in the general farms approached to about 15.8-37.1 lit./day per cattle, 3.87-16.45 lit./day per a pig, and 0.19-1.03 lit./day per chicken, but it was slightly reduced in autumn; 10.89-37.09 lit./day per cattle, 3.87-12.63 lit./day per a pig, and 0.06-0.94 lit./day per chicken. The ratio of livestock water consumption to home use amounted to the range of 10-25%. 3. The mean consumption of livestock water used at the livestock raisers amounted to 134 lit./day per dairy cow, 67.4 lit./day per cattle, 43.29 lit./day per a horse, 13.24 lit./day per a pig, 0.438 lit./day per a layer, and 0.177 lit./day per a broiler, which showed that the daily water consumption for larger livestock was about two times as much as the farms, but it was approximately of the same for small ones. 4. The factors affecting the amount of water consumption for home use were statistically analyzed to find the kind of water sources and the class of water systems by the factorial arrangement method to the fundamental experimental unit, Suwon area of 100 of families, in which the former was very significant while the latter was significant. However, the standard of living and their interactions were not significant. 5. Almost 83.24% of the sampled farms used some kinds of wells as their water sources, of which 32.06% was of hard water, and of which 11.l% or 2.6% contained much of iron or organice materials, respectively, examining them by a simple technique of sensibility, 6. The resulting chart of the farm water systems was summarized as Fig. IV-6. Observating the safe distance from contamination sources, the ratio of 42.4% of sampled farms whose water sources were wells, confronted highly to the danger of contamination to their water sources. And other dangerous sources of contamination such as toilets, stalls, and compost heaps were situated nearly to the water sources, and most of them were able to make their spoiled water infiltrated into the ground. Thereafter, it was recommended to develop some protecting methods and to install some suitable faculties to clean water.

  • The schools in the survey consisted of 61 schools where foodservice was managed by themselves and 49 schools where it was done cooperatively. According to the style managed, the urban style was 42 schools, the rural style was 46, and the island style was 22. With regard to the amount for each student that parents have to pay. it was 745 won at schools managed by themselves and 616 won at schools managed cooperatively. The budgeted amount was 75 won at schools managed by themselves and 97 won at schools managed cooperatively. The result showed that parents at schools managed for themselves paid much more for the cost of food and management. The mean area of kitchens was 31 pyong (102 sq. meters) in environment of cooking utilities, and management was done wherever they were needed. The budgeted amount was supplied from the Educational Office and parents. In the situation of utilities and instruments for cooking, the places to wash hands and flush toilets, which were regarded as sanitary facilities were insufficient. The rates of containing measuring instruments and thermometers for cooking were also insufficient. The list to be considered in the management of menu was concentrated on raising acceptance of students served, based on the order of the tastes of students served, the quantity of the cost, nutrition needed, and then facilities. The replies that leftover food was thrown away after meals were numerous and the rate of leftover food was reflected on the menu. In purchase and management, the rate of food needed to be purchased was calculated through experience. A private contract was chosen to purchase food. The frequency of purchasing food was usually once a day, which would nutritists examined food, concentrating on the order of quality, number, and price. In the management of operation, a schedule for making food was seldom formed, referring to it only at the time needed. All the food was made in a day but some special foods were made the day before they would be required. It shows the situation was thought to be the most important. Guidance for sanitation was carried out once a month and the content of the guidance was about the sanitary treatment of food. With regard to degree of satisfaction with the management of meal service, all the dietitian at schools managed for themselves and cooperatively were somewhat satisfied with all the questions about the budgeted amount of food, and management, the management of purchase, operation, and sanitation. However, they were not satisfied with the environment of facilities.

  • Human exposure to volatile compounds in tap water can occur from inhalation and dermal absorption as well as direct ingestion. The relative contribution to total human exposure from these pathways has been considered to be important especially for VOC's (volatile organic compounds). In an attempt to reduce the uncertainty of the risk assessment, it has been suggested that the exposure assessment process could be significantly improved by adopting Monte-Carlo simulation. However, there is no actual data in Korea for each exposure parameter to determine the level of exposure, and the distributional pattern. Therefore, we surveyed water use patterns and behavior related to multi-route exposure to VOC's in household tap water in Korea, and compared these values to the those in western countries. In the first survey, we calculated daily water intake using data from a sample of 1322 persons of several cities in Korea. In the second survey, we obtained questionnaire data on exposure time for showering, bathing and household activities, and tap water intake from 851households in Korea. In the last survey, we measured the exposure parameters (exposure time, water use rate etc.) related to showers, baths, toilets, dish washing, washing and cooking, and tap water intake was surveyed. Also, the subjects were measured their body weight, height and tidal volume, etc. A diary, a flow meter and a measuring cup were used to measure these values as precisely as possible. Average daily water intake was ranged 0.79-1.71 L/day for adults in three surveys. Tap water intake measured by log-sheet during one week in third survey was 1.26 (average), 1.98 L/day (90 percentlie), respectively. These results were comparable with results from EPA (1.4, 2L/day). The average amount of water used by housewives in the third survey was 515.0 $\pm$ 564.6L/day. In usual activity, the amount of water used in the bathroom, the laundry and the kitchen was 140.0 $\pm$ 538.9, 148.0 $\pm$ 174.5, 229.3 $\pm$ 205.4 L/day, respectively. Exposure parameters such as water intake rate, exposure duration, body weight, inhalation rates in surveyed data of Korean people differed from those published from western countries. This could be attributed to variations in lifestyle, dietary habits and physiological characteristics.

  • The number of the disabled is increasing every year. Growing interest in social welfare, but still the disabled person in places is restricted on the activities are due to obstacles. This study proposes an improvement direction through an research and analysis of installation status of convenient facilities in social welfare halls was planned after that the law of increase of convenience for the disabled person is enforced in 1998. This study analyzed nine social welfare halls of seoul including Yongsan-gu(GW), Guro-gu(GD, HW), Yeongdeungpo-gu(SG), Seodaemun-gu(SD), Dobong-gu(DB), Nowon-gu(NS), Seongbuk-gu(WG) and Dongdaemun-gu(JG). The evaluation criteria for the installation of convenient facilities for the disabled person in each social welfare hall based on the law of increase of convenience for the disabled person, and referred to other data. Also, review the criteria for the installation of convenient facilities, and grasp the present situation through the survey of convenient facilities in social welfare halls, and provides the installation standards of convenient facilities. The result are as followings. There were many problems to be improved in approach of the intermediate space, parking lot, entrance of the inside space and corridor that must be installed for the convenience of the disabled. In the intermediate space, the slope of the ramp, curb, induction handle etc. for a safety must be installed. Parking spaces for the disabled must be located closest to the main entrance, an induction marker or the handle, and the attachment of a directional sign etc. must be improved. In the inside space, it is convenient for the disabled person use to install an automatic door and swing door simultaneously at the main entrance. And, the height of the door handle, an induction block, a braille display panels of the appropriate height in the entrance, a braille display in start and end of the stairs handle, the handle of the side wall, the stairs to prevent slippage etc. must be improved in the corridors. The case of the sanitation which is a recommendation item is equipped formally with disabled toilets are difficult to use. Information and other convenience facilities for the disabled person in all the social welfare halls were not considered.
