최근 급격한 인터넷의 발전은 검색 서비스로 인해 주도되었다고 해도 과언이 아닐 것이다. 방대한 정보의 바다 인터넷을 통해 정보를 얻으려 해본 적이 있다면 어떤 검색엔진을 사용하여야 할지 어떤 검색어를 사용하여야 할지 한 번쯤은 고민 해 보았을 것이다. 이러한 이유로 많은 사람들이 메타 검색엔진이라는 것을 이용하게 된다. 그러나 이러한 메타 검색엔진도 자체내의 여러 가지 정보 처리로 인한 느린 결과 처리의 문제점이 있다. 본 논문에서는 인터넷의 정보검색을 하는 사용자의 특성을 고려한 정보 검색 서비스를 제공해 주는 시스템을 설계 구현하여 본다. It is needless to say that information search service leads explosive growth Internet. When you have a experience to get information what you search in Internet, puzzled about what kind of search engine and search keyword should select. Thus many people want to use Meta-search engine. But Meta-search engine has some problem. one of problem is that meta-search engine manages information which is obtained by several search engine. Thus meta-search engine has some severe performance degradation. In this paper we designed and implemented information search service system for the purpose of using internet to get information search result.

The objectives of present study is to investigate genetic damage of radiation in mammalian male germ cell and to establish available screening method for determining genetic hazard by radiation. Several methods were employed to measure the genetic damage of radiation as follows: Sperm head counts, frequency occurrence of sperm with abnormal head shape, fertility, activity of LDH-X, and the induction of unscheduled DNA synthesis (U.D.S.) in male mouse were performed with the passing of time after irradiation by making use of the sequence of event that occurs during spermatogenesis. Sperm head counts and activity of LDH-X in testes were gradually reduced by increased radiation dose and with the passing of the time after irradiation. Frequency occurrence of sperm with abnormal head shape, sterile period, and the induction of unscheduled DNA synthesis were increased by increased radiation dose. It is suggested that since germ cell is a direct reflection of genetic complement, the use of male germ cell is rapid and convenient method for measuring genetic damage by radiation.

The High-Technology Park can lead various regional developments through the level-up of industrial structure by settling technology intensive industry resulting from the investment toward high-technology industry. The purpose of study is to seek for ways of the revitalization of High-Technology Park as new methods for regional development. Study site is the High-Technology Park in Chonju City which is currently building up. Study purpose is performed through survey and analysis of actual situation. At first, theoretical study and examples of internal and external high-technology park are conducted, and then methods for revitalization of it are suggested through the outline of development, the research of the related policies and the questionnaire to experts. The results on this study are as follows, 1. To revitalize the high-technology park through inducing companies, establishing Enterprise Introduction Committee, which guides the policy and financing support of government and cooperative activities of government and public, is one of very efficient ideas. 2. To overcome the current poor sale in lots and to make the high-technology companies be rapidly set up, which is the most important thing for the revitalization of high-technology park, the current method to sell in lots may be changed into renting them. 3. To actively induce companies, the foundation of research institutes or supporting organization is urgent. Especially, in case of High-Technology Park in Chonju City, Techno-Park or Venture Enterprise Site is adequate type. 4. To revitalize High-Technology Park in Chonju City, the technological cooperation among related enterprises and the cooperative systems among industrial, academic, and governmental organizations as ways to promote the technology are needed. 5. To improve the effectiveness of promoting technology, those institutes or organizations are indispensable. Therefore, first of all, the Incubator of High-Technology Human Resource is right one for Chonju City.

This study was conducted to investigate the relationships between yearly variations of climatic factors and yearly variations of productivity in red pepper. In addition, correlation coefficients among the yield and yield components were estimated. The data of yield and yield components were collected from the statistical Year Book of Gurye province, Research Report of Gurye Extension Station of Rural Development Administration, and farmers for ten years from 1987 to 1996. The meteorological data gathered at the Sunchon Weather Station for the same period were used to find out the relationships between climatic factor and productivity. Yearly variation of the precipitation in September with coefficients of variation(C.V.) of 84.71, but the variation of the mean temperature in May and June were relatively small. Yield and fruit diameter were large with coefficients of variation(C.V.) of 15.63, 18.09%, but the variation of fruit length and fruit weight were small with 6.27%, 10.42% respectively. Correlation coefficients between duration of sunshine of Aug. and yield, yield components are negative significant at the level of 5, 1%, respectively. Duration of sunshine of Aug. would be used as a predictive variable for the estimation of yield and flowering data. Simple linear regression equations by the least square method are estimated for flowering data (Y_1) and the duration of sunshine of Aug.(X) as Y_1=-580.5527+21.6301X(R_2=0.4761), and for yield (Y_2) and the duration of sunshine of Aug.(X) as Y=-76.0402+1.0705×(R_2=0.5131)

농촌진흥청 목포시험장에서 1998년까지 시험한 대마의 재배법 재선 연구중에서 앞으로 실시해야 할 생력기계화 직파재배의 기초가 될 몇가지 시험성적을 정리하였던 바 그 결과를 요약하면 다음과 같다. 1. 남부지방에서의 대마 직파재배의 파종적기는 3월 15일이었다. 2. 적정재식밀도는 휴폭 40cm×주간 5cm가 가장 적당하였다. 3. 직파재배의 시비수준에 대한 반응은 적합하였고 퇴비는 10a당 1,000㎏이 가장 좋았다. Experiments were conducted to reduce the labor and production cost by using the machine in hemp. The results are as follows: The recommendable sowing date and planting space seemed to be Mar. 15 and 40×5cm, respectively. The optimal fertilizer level were with compost of 1,000㎏/10a. The ratio of peeled fiber yield and fiber yield was the highest in the sowing date of Mar. 15, planting space of 40×5cm and fertilizer level of

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

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)
