The authors surveyed the clinical study of 17cases of scaphoid fractures from March 1989 to September 1994 with minimal I year follow up at Department of Orthopedic Surgery, Lee-Rha general Hospital. The following conclusions were obtained through clinical survey. l. Of all l 7 cases, they were l3 males and 4 females; Among the 13 males, 10 cases were aged between 20 and 39 years. forming 56.8% of all. 2. All 17 cases were treated by open reduction. Unions were obtained at average l l.5 weeks in 7 cases treated with Herbert screw fixation and l 2 weeks in l 0 cases treated with K-wire fixation. 3. Two of ten K-wire treated cases resulted in delayed union, one of seven Herbert screw treated cases resulted in delayed union. 4. Unions were obtained at average 20 weeks in 3 cases of delayed union. We concluded that open reduction and K-wire fixation were recomanded for the compatible treatment method of displaced waist fracture of scaphoid.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)

This study attempts to analysis the present situation of farm management and the related industriesin order to present the suitable industries for promoting the farmers' income in mountain area. This study is based on the survey data obtained from 30 sample mountain vellages in 10 Guns located in central, wetern and northen Kyeougnam Province, where lots of mountain vellages are scattered here and there. Major findings obtained from the analysis are summarized as follows: 1) Area of cultivated land in mountian villages was generally smaller than that in plain vellages. BUt major finding of thes tudy indicated that the standard of living in the study area depended upon not only the size of cultivated land but also the skills of management to understand exavtly the regional and togographical situaltion, to utilize the developmental resources effectively, and to diversify income sources. This means that upbringing of competent Saemaul leaders is very important for promoting the income of mountain villages. 2) Various crops were being planted in a samll scale inmountain area. And those crops except rice adn barley were planted for self-sufficiency. Therefore, it is desired to select and cultivate intensively the kinds of crops which are regionally adn topographically suitable for maximizing farm inceomes of subsistant farmers. 3) The survey found out that in mountain area the farming of extensive fruits like chestnuts, persimmons, etc. is more favorable than that of intensive fruits like apples, pears, etc. 4) Because of topographical inappropriateness and lack of fertile cultivates land in mountain area, mowt vegetables, except onions in a few regions, were growing in a small scales for self-sufficiency. And the future of the vegetable cultivationin mountain area is also gloomy. 5) Since various grasses are abundantly growing in the wild in mountain area, the mountain villages are suitable for raising the herbivorous animals. Therefore it is recommeded to encourage raising the herbivorous animals, especially cattle, as one of the major income sources in mountain area. 6) It is true that sericulture has greartly contributed to the economic growth in mountain area with aboundant land suitable for mulberry trees. Recenly sericulture has, however, been shrinking due to the barriers of silk exportation. Without the barriers of silk exportation, sericulture will still play an important role on providing one of the major sources tom mountain villages. 7) The miscellaneous trees in most forest around the mountain villages were growing planlessly. Those parts of the forest are needed to be renewed by planting the useful, endurable, and regionally and topographically suitable kinds of trees.

李吉雨,金泳祥 홍익대학교 산업기술연구소 1996 産業技術 Vol.6 No.-

In recent years machining turns to flexible manufacturing. Industry in machining requires to increase machining productivity and to reduce costs. To adapt this trend it is necessary to optimize machining condition Even though many researches in this are introduced various way to set the optimal condition, still there are not enough. Therefore this research was done to select the optimal cutting condition for industry, and to develope the computer program to select the optimal cutting condition automatically. Also, this program was applied to many companies, and compare costs per minute. The results of this research will contribute to increase machining productivity of various companies with the automatic selection of optimal cutting condition.

이 연구는 1993년도에 우리나라의 연간 슬러지발생량이 약 3500만m³에 이르고 있으며, 이들 대부분이 매립되고 있다. 그러나 매립부지의 확보가 점점 어려워 지고 있으며 아울러 매립처분비용도 상승하고 있기 때문에 oil화, 퇴비화등으로 재자원화 하는 방법과 소각후의 소각회를 유효이용하는 방법 등이 연구 개발되고 실용화되고 있다. 슬러지의 oil화는 현재 연구단계에 있으나 앞으로 슬러지의 유효이용기술로서, 가장 좋은 방법이 되리라 기대되고 있다. 그러나 소각후의 소각회의 이용방법은 현재 일본등에서는 실용화 되어 건설자재 등으로 다양하게 이용하고 있다. 우리나라에서도 서울시 등을 비롯한 대도시에서는 하수처리장에서 발생하는 슬러지를 소각한 후에 소각회를 건설 자제용으로서 지자체의 공사에는 반드시 사용하도록 하는 제도를 만든다면 유효이용방법으로 충분한 타당성이 있을 것이다. 이때 소각방법으로는 용융소각방법이 보다 효과적일 것이다. With increasing sewage and wastewater sludge, it has become difficult to dispose the sludge by landfilling and ocean dumping. To solve this problem, efforts have been made to delelop sewage and wastewater sludge utilization technologies in many advanced countries. Some technologies have already been developed; conversion of sludge to compost and fuel, producing artificial light-weight aggregate from ashes. This paper describes the technical status of sludge utilization technologies.

We can save the moving time for taking part in meeting through the remote conferencing system. We can quickly make a decision by using video conferencing system in real-time. In this paper, we designed an prototype model of multimedia conferencing system that contained the CSCW concept. The designed system is composed of audio server, video server, and document server, and they formulate audio subsystem, video subsystem, and document subsystem respectively. The result of this paper can provide base technology of implementing conferencing system, which may be enough to develop multimedia conferencing system for using voices, still images, full motion images in communication protocol.
