Purpose: The present study purposed to compare the hand washing effect of 7.5% powidone-iodine, which is used in the operation room of C university hospital in Seoul, with that of Ethyl alcohol-CHG mixture recommended by the US Association of Operating Room Nurses (2002) and to adopt a more effective hand disinfectant. Method: In a quasi-experimental design, 48 medical staff who participated in operations during the period from November 2004 to February 2005 had hand washing using the two kinds of hand disinfectants: 7.5% povidone-iodine and the ethyl alcohol-CHG mixture. Their palms were swabbed and cultured just after hand washing and again after taking dff sterile gloves after the operation. The number of colonies from the two occasions were counted and compared. Result: The number of general bacillus increased significantly in the group using 7.5% povidone-iodine compared to that in the group using the ethyl alcohol-CHG mixture. The number of general bacillus increased signficantly in doctors compared to that in nurses. The factors affecting the increase of the number of general bacillus were disinfectants and medical personnel. The number of general bacillus was expected to increase 9.41 times with 7.5% povidone-iodine than with the ethyl alcohol-CHG mixture and 14.87 times in doctors than in nurses. Conclusion: This study shows that the ethyl alcogol-CHG mixture has a stronger hand disinfection effect than 7.5% povidone iodine. Thus we need to change the hand disinfectant used in operating rooms as soon as possible in order to minimize the infection of wounds resulting from operations.

The number and distribution of the retinal ganglion cells in the 1-week-old and 7-week-old ducks were determined from whole flat mounted preparations stained with methylene blue and thionin. The results were summarized as follows. 1. In the 1-week-old and 7-week-old ducks, the areas of the retinas were 269.4㎟ and 357.2㎟, respectively, and the total cell numbers 1,742,800 and 1,808,800, respectively. 2. The ganglion cells based upon soma diameter were classified into 3 groups such as small (below 10㎛), medium (10-20㎛) and large (above 20㎛) ganglion cells. In 1-week-old duck, the relative frequencies of these 3 groups were 91.0%, 8.5% and 0.5%, respectively, and in 7-week-old duck, 83.7% 14.7% and 1.6%, respectively. 3. Area centralis was located at the distance of 1.6mm (1-week-old) and 2.0mm(7-week-old) nasal side from the anterior tip of the pecten. The number of ganglion cells in the area centralis was 11,000 cells/㎟ (1-week-old) and 12,000 cells/㎟ (7-week-old). 4. There was a gradual decrease in density of retinal ganglion cells extending from area centralis to the periphery of retina. 5. The density of the large (above 20㎛) ganglion cells was higher in the peripheral regions than in the center of retina. Higher densities were noted in the superior-temporal region in 7-week-old duck, and in the nasal region in 1-week-old duck than in the other regions. 6. The direction of the beak tip is approximately 30° in 1-week-old and 26° in 7-week-old duck from the angle of the pecten.

목 적 : 하청노동을 이용한 노동 유연화 전략은 근로자들의 고용을 불안정시키고, 근로자들의 삶에 부정적 영향을 미치고 있다. 따라서 이 연구는 하청업체 근로자들의 고용현황을 조사하고, 기존의 업체중심의 건강평가의 문제점을 지적하고자 하였다. 또한 하청업체 근로자들의 건강평가의 현재적 의미와 사회적 배제의 특성을 알아보고자 하였다. 방 법 : 모기업과 하청업체 근로자들의 건강수준을 비교하기 위하여, 정기건강진단(일반, 특수)과 채용건강진단 자료를 이용하고자 하였다. 건강진단에서 누락된 비정규직을 포괄하기 위하여 SF-36을 이용하여 건강설문조사를 시행하였다.결 과 : 조선업 하청업체 근로자들의 고용기간은 짧고, 빈번한 노동이동 현상을 보였다. 3년간 건강진단 수검 현황을 통해 살펴볼 때, 1998년 수검자중 2000년까지 연속해서 검진 받은 수검자는 40.3%였다. 건강진단 결과 유소견자 규모를 통해 모기업과 하청업체간의 건강수준을 비교해 보았다. 모기업은 일반질병 요관찰자와 질병자를 포함한 유소견자가 1,011명으로 약 10 %의 유소견율을 보이고 있고, 질병자의 경우 596명으로 유병률이 5 %를 상회하고 있다. 반면 하청업체의 경우 1,967명의 수검자중 유소견자가 115명으로 6 %의 유소견율을 보이고있고, 질병자는 82명으로 4 %의 유병률을 보이고있다 채용건강진단을 받은 수검자는 6,260명 이었으며, 이 중 유소견자 수는 2,373명으로 전체 수검자의 37.9 %를 차지하였다. 건강설문지의 경우는 전체 건강수준의 총합은 하청보다 원청 근로자가 높았고 통계적으로 유의하였다. 결 론' 정기건강검진 결과는 하청근로자들이 고용형태에 따라 검진을 받지 못한 경우가 많아, 건강 근로자 효과로 표현될 가능성이 있다. 따라서 채용건강진단 결과는 다른 측면에서 하청업체 근로자들의 건강수준의 현실적 반영이라고 할 수 있다. 향후 하청업체 근로자들의 건강문제를 감시하고 개선하려면 기존의 업체 중심의 접근으로는 하청 근로자의 건강문제를 제대로 다룰 수 없고, 업종과 지역을 동시에 고려하여 접근할 필요가 있다. 또한 단기 고용 근로자 및 비정규직 근로자를 사회보장의 확충과 모기업의 연대책임 강화 및 기업복지 차원에서 포괄하는 방안이 모색되어야 하겠다. Objectives : The strategy for the labor flexibility through subcontracted labor have brought a negative effect on the lives of the workers, such as the increase of the unstable employment. This study was conducted to analyze the relationship between the employment of subcontracted firms and the health status of them, and to find out some problems which have been caused in the process of health evaluation and the characteristics of social exclusion. Methods : We reviewed the periodical health examination and preemployment health examination in order to compare health status of the subcontracted workers with those of the parent firm workers. The SF-36 questionnaire was administered to assess the self-perceived health status. Results : The result shows that compared to the working duration of the parent firm workers, those of the subcontracted workers were shorter, and the job transfer rate was higher. In the periodical health examination, the prevalence of occupational and general disease was higher in the parent firm(10%) than in the subcontracted firms(6%). Preemployment health examination plays an important role in worker's health manage- ment. Among 6,260 workers who received preemployment health examination, the prevalence of disease was 37.9%. Mean scores of health status measured by SF-36 were lower in the subcontracted firm than in the parent firm. Conclusions : Due to social exclusion of the subcontracted workers from the periodical health examination, there is a possibility that the periodical health examination have the healthy worker effect. These results suggests that the preemployment health examination could be a more appropriate indicator which is able to assess the health status of the subcontracted workers than the periodical health examination.

Rural of Koreas has rapidly changed through the process of industrialization and urbanization. During past 30 years, development differences between urban and rural, metroplitan area and area derived from a highly economic growth, bring about dual specialization that deepens overpopulation and sparsity. Therefore, with a new concern about rural, necessity of rural development policy that developes a settlement and life area for settlement for ensuing stablized settlement and living activity of rural people, has been drived step by step. For rural welfare establishment that is settled and good hereafter, this study aims at attempting a theoretical approach about the way of development for rural settlement as a new rural development strategy through examination of today's rural reality, under assumption that rural people must be able to obtain stable jobs and to be pleasant without leaving rural area, and rural settlement to be able to enjoy urban advantages must be realized. Therefore, items that must be obtained basically rural area to be a human settlement space are equipment connected with a dwelling house, production, consumption, job relaxation, infrastructure connected with transportation or communication network and environment. By the way, the best function of a human settlement space makes a basic pleasant settlement area to be in the middle of that. Then rationalization of land use must be realized as being a best condition for human life around space of a dewelling house. Besides, spacial accessibility about all equipment of inhabitants must be easy. That is, economic distance, social distance and cultural distance as well as spacial distance must be included. Also, those spacial functions must be realized on a basis of suitable enironment for a human settlement life. At the same tiem, the upper area must be connected with the lower area as the system of spacial settlement in settlement space. But truely, as rural people can't satisfy with services of the surrounding rural areas, they desire better city or metroplitan. The these problems bring about inequality between urban and rural. Therefore, here are urgent reasons that must be done rearing of rural central town and rural integrated development of unit area. So, these dys, to correct maldistribution of land use and inequality of settlement space that Korean society faces on, new strategies of rural integrated development for lift area for settlement than gives the meaning. That rural areas become like a place for human settlement life will be able to be chosen in the view of humanism. The say of thinking of rural residents(Jukans-myun, Anseong-gun, Kyeonggi-do) was surveyed in order to develop new rural settlement planning. From the data collected in this survey, rural life-style, view on traditional rural life, agriculture, farming, agri-policy, social attitude, and degree of satifaction of rural life, etc, were analyzed. Firstly, most of rural residents interviewed in this survey have the opinion of not leaving their home village if living conditions improved to a reasonable level in the near future. In decision-making process of village affairs, they want to participate actively and equally. Secondly, in spite of their acceptance of agriculture as a vital sector destined to national security, most of them think that framing should be little of promise. Thirdly, they have the negative attitude to urban-oriented social valued and also to the agricultural policy, while seeking consolation through human and traditional viewing of rural life style. Therefore, in the development of new rural settlement model, idea-making should be directed to the betterment of communal value of village life, stability of rural economy, rationalization of rural life style and enhancement of rural-type happiness.

직업성 질환에 관련된 다양한 진료를 체계적으로 수집하고 관리하여 직업성질환의 예방 목적으로 이를 활용하고 자하는 노력이 우리나라에서도 이제 다양한 방법으로 시도되고 있다. 최근의 자료 시스템의 구축과 관리 방법의 향상은 새로운 직업성 잘환감시방법을 개발하게 하여 직업성질환과 손상을 예 방하는데 크게 기여하고 있다. 우리나라에서도 기존의 산업보건사업의 성과를 계승하면서, 외국의 직업성질환 감시의 여러 경험을 비판적으로 수용하여 한국적인 직업성질환 감시 모델을 구축해야 할 것으로 생각된다. 자발적인 지역차원의 직업성질환 감시체계들이 틀을 잡아가고 있는 이 시점에서 본격적으로 직업성질환 감시체계 수립을 위한 전략과 구체적 방법론을 마련하고 공유하여야 할 필요가 있다. 이를 위하여 우리나라의 직업성질환 감시체계를 구축하는데 기초가 될 수 있는 직업성질환 감시체계의 계획과 관리에 대한 내용을 정리하였다. 이러한 감시체계를 우리나라에 정립하려는 노력들의 일환으로 최근 직업성질환감시연구회의 결성 및 각 지역의 직업성질환 감시체계의 운영 등이 조금씩 결실을 맺어가고 있어 간략히 소개하면 다음과 같다.첫째, 최근에 인천, 천안, 대전, 여천, 구미 등에서 지역단위의 직업성질환 감시체계를 구축하고 있고 한국산업안전공단에서는 특수건강진단과 작업환경측정 자료를 전산화하여 이를 직업성질환 감시에 사용하는 전국단위의 감시체계와 천식, 근골격계질환, 피부질환 등 질환별 감시체계 등이 시도되고 있다.둘째, 이러한 움직임은 과거에 비하여 한층 발전된 양상이고 바람직하지만 이제는 국가적 차원에서 직업성질환 감시체계를 어떻게 설정하고 조율할 지를 고민하고 계획하여야 할 때이다. 즉 한국산업안전공단과 지역단위 직업성질환 감시체계들의 역할분담과 상호 정보의 교류 등이 정리되어야 이를 바탕으로 유기적인 국가 직업성질환 감시체계가 구축될 수 있다.셋째, 이를 위하여서는 직업성질환 감시체계 구축의 방법론을 서로 교류하고 공유할 필요가 있으며 나아가서는 이를 표준화하여 기본적인 자료의 교류가 원활하게 이루어질 수 있도록 하여야 한다. 이러한 역할은 최근에 결성된 직업성질환감시연구회와 산업안전보건연구원, 그리고 대한산업의학회, 산업간호학회, 산업위생학회 등이 협력하여 학술적인 작업과 함께 실무적인 지침을 만들어나가도록 하는 것이 바람직할 것이다.

Zeolites were synthesized from fly ash and used as catalysts for pyrolysis of polypropylene(PP) Zeolite synthesis was carried out by fusion methods employing three different NaOH/Fly ash rations in weight The catalytic performance of the fly ash-derived zeolite pyrolysis products. The properties of the fly ash-derived zeolites were characterized by XRD, SEM, BET, NH_3-TPD. It was found that the optimum NaOH/fly ash weight ratio was 1.2 in terms of the simulated boiling point distribution. The catalytic perfomance of the fly ash-derived zeolite was significantly improved by ion exchanging of zeolite from Na from(FAZ) to H from(HFAZ) The boiling point distributions of liquid pyrolysis products obtained over HFAZ were significantly lower than that obtained zeolite.
