尹畯相,李武鉉,申尹撤,洪性贊,朴奉圭 公州大學校 産業開發硏究所 1994 産業開發硏究 Vol.2 No.-
Since the first year economic development plan, imblanced development of national territory during the economic development process has aggravated remarkable disparity between urban and rural areas. For this reason, this study introduced the development of rural market as one of the development strategies of regional economic to correct the imblance and relieve regional disparity. The purpose of this study were to look into the present situation of traditional rural market and to analyze the problems for the rural development in view of the current road situations in the rural areas and status of marketing facilities in market center and to measure the degree of rural area people's satisfaction to the rural market and to suggest the development plan of activating for rural market center. To collect data, the Yesan Gun rural market were selected and a total of 591 residents and 178 merchants were sampled as final subjects of survey. Interview and/or questionnaire method was the main method of data collection. The major findings of this study were as follows: 1) The population of Yesan Gun has decreased 2.85 persons per year from in 1984, but the number of vehicles were increased 2.85 times than in 1989. And the parking capacity of Yesan Eup was only 129 vehicles which were below of the total vehicles of Yesan Gun area (14,352). The number of Yesan area markets were 8 markets which consisted of 1 permanent market and 7 periodic markets. But as the economy has been developed, the conditions of rural markets have been changing. That is, the role of periodic market tends to be weakened with the growth of large cities, reinforcement of permanent markets, development of traffic facilities, large production, preferring high quality goods. 3) Generally, the people of Yesan Gun were attached for purchasing the necessaries of life and comodities and farming materials to ① Yesan Eup ② Seoul ③ Chonan Shi ④ Hongsung gun ⑤ Daejeon Shi. 4) The degree of community people's satisfaction to the town market presented 26.6% which meaned higher than dissatisfaction(9.5%). And the degree of people's inconvenience of accessibility to market center by transferring of bus terminal presented 64.2% which meaned higher than average. 5) The degree of people's dissatisfaction of traffic system in Yesan gun area presented followings: the road networks(61.5%), parking facility(68%), bus route(54%). 6) By the survey of merchants of Yesan gun area, on the average, it showed followings: the size of store was 6-10 pyeong(40%), the type of enterprise was retail dealer(70.9%), and purchasing place was wholesale dealer from Seoul(51.8%). 7) And they thought that Yesan town market were too small(70.8%), and the diversifying of goods was not enough(35.5%). 8) The merchants of Yesan area showed that the degree of into venience to traffic system was 72.7% and its to parking facility was 83.3%. And they complained that community administration agency have not tried to activate market(79.1%). Based on the results of this study, the following recommendation were made for activating regional economy and community market. That is, it is to strengthen the economic function in community market so as to suffice the economic and social activities for settlement area as their living space. And it is necessary to improve the interrelationship of the central functions. 1) So, the accessibility between market center and its surrounding areas must be rised. ① the enforcing preferentially to pave the bus terminal and market center to link two place. ② the running of shuttle-bus two place every regular market day. ③ the widening and connecting the road to rise accessibility between market center and its surrounding area. ④ the enforcement of parking facility around market center. ⑤ the constructing marketing centered area as intergrated body of various marketing facilities in the adjacent site is the centered area planned to achieve efficient marketing. 2) The modernization and specialization market center facilities. 3) The strengthening of drawing surrounding area people into Yesan market center. So, the following recommended: ① the development of special products market ② inducing special projects ③ the development tour and leisure course drawing industrial facilities. 4) And it needs to enforce community people's local patriotism and to support community markets by administration agency.

이재형,우엄찬,박무훈,최중경,하판봉,김영희 국립7개대학공동논문집간행위원회 2005 공업기술연구 Vol.5 No.-
A half-VDD voltage generator(VHDD) using PMOS pull-up and NMOS pull-down transistors, and each of the gate voltage is able to swing at CMOS voltage level was newly proposed. Designed with these, pull-up current was made to be proportional to (VDD-|V_(TP)|)^2 and pull-down current was made to be proportional to (VDD-|V_(TN)|)^2. Also, being turned on pull-up and pull-down transistors at the same time was prevented by using short-circuit current protection circuit. Test chips which were designed by using 0.35μm CMOS twin-well process technology were fabricated and the result of measurement was suitable for low-boltage DRAMs.

정성윤,박영태,김무찬,최석철,성희경,김재영,김태운,이원재,JEONG Seong-Youn,PARK Young-Tae,KIM Mu-Chan,CHOI Seok-Cheol,SEONG Hee-Kyung,KIM Jai-Young,KIM Tae-Un,LEE Won-Jae 한국수산과학회 2000 한국수산과학회지 Vol.33 No.4
적조생물을 살조시키는 해양세균 Microcorcus sp. LG-5가 생산하는 세포외 분비 살조물질의 최적 생성조건, 살조물질의 특성과 한외여과 분획별 살조활성 및 해양생물에 미치는 영향을 조사함으로서 자연생태 조화형, 환경 친화적 적조방제 기술개발의 기초 자료를 제공하고자 연구한 결과를 요약하면 다음과 같다. Micrococcus sp. LG-5의 살조물질 생성 최적온도는 $20{\~}30^{\circ}C$로 살조활성이 $100{\%}$였으며, 살조물질 생성 최적 pH는 7.0, 최저 염농도는 $3.0{\%}$였다. 또한 세포외 분비 살조물질의 $IC_(50)$ 값은 $0.482{\%}$였다. 세포외 분비 살조물질의 열 안정성을 실험한 결과, 열처리한 배양여과액 $1{\%}$ 첨가시 12시간 후에 $31.4{\%}$, 24시간 후 $79.7{\%}$, 36시간 후 $94.6{\%}$의 살조활성을 보였고 $5{\%}, 10{\%}$의 경우 각자 36시간, 24시간 후에 $100{\%}$ 살조되었으며, 열처리하지 않은 배양여과액을 넣었을 때와 비교해볼 때 살조력에 유의한 차이는 없었다. 이와 같이 Micrococcus sp. LG-5가 생산, 분비하는 살조물질은 열에 안정한 내열성 물질로 판단된다. 또한 대사산물의 pH 안정성은 $pH 6.0{\~}8.0$에서 거의 $100{\%}$의 살조활성을 보였으며 $pH 5.0{\~}10.0$에서 살조활성이 $85{\%}$ 이상으로 나타나 살조물질은 약산성과 알카리에서 살조활성이 안정하였다. 또한 한외여과의 결과, 분자량 $>10,000, 10,000{\~}1,000, <1,000$의 3개의 분획 모두 살조활성이 있었으며, 각 분획 모두 열에 대단히 안정하였다. 각 분획별 $IC_(50)$ 값은 분자량 1,000 이상에서 강한 살조활성이 나타났으며 분자량 1,000 이하에서는 상대적으로 낮은 살조활성을 보였다. Micrococcus sp. LG-5가 해양세균에 미치는 영향은 E. faecalis, E. coli, K. pneumoniae 및 V. alginolyticus에 대해서는 항균력을 보였으나, P. aeruginosa, P. fluorescens, S. typhi, S. aureus, V. cholerae 및 V parahaemolyticus에 대해서는 전혀 항균력을 보이지 않았다. 그리고 적조생물에 미치는 영향은 A. tamarense, E. gymnastica, G. catenatum, G. niikimotoi, G. sanguineum, G. impudicum, H. triquetra, H akashiwo, P. micans와 Pyramimonas sp.에 대해서는 살조활성을 보였으나 Chlamydomonas sp., C. closterium, P. mininum, P. triestimum, Pseudonitzschia sp.와 S. trochoidea에 대해서는 살조활성을 보이지 않았다. 즉, 적조생물에 따라 살조활성이 다양하게 나타나 종 특이성이 낮았다. 먹이생물에 미치는 영향은 1 galbana를 제외하고 실험한 모든 먹이생물에 별다른 영향이 없거나 오히려 성장을 촉진시켰고, 또한 살조세균 배양여과액을 넙치 사육수에 $10{\%}$까지 투여하였을 때 양식 넙치에 미치는 유해한 생리학적 영향은 없었다. 이상의 연구 결과 살조세균 Micrococcus sp. LG-5의 배양여과액은 조사된 적조생물을 제외한 해양세균, 치${\cdot}$자어의 먹이생물 및 양식 넙치에 유해한 영향은 미치지 않을 것으로 판단된다. An algicidal bacterium, Micrococcus sp. LG-5 against the harmful dinoflagellate, Cochlodinium polykrikoides was isolated. The optimal conditions for the highest algicidal activity of bacterial culture filtrate showed in the range of $20{\~}30^{\circ}C$, at pH 7.0 and $3.0{\%}$ of NaCl concentration. In addition, $IC_(50)(mean of 50{\%} inhibitory concentration)$ of the culture filtrate against C. polykrikoides after incubation of 5 days was $0.482{\%}$. To investigate heat and pH stability of the culture filtrate of Micrococcus sp. LG-5, the culture filtrate ($pore size, 0.1 {\mu}m$) was heated to $121^{\circ}C for 15 min$ and adjusted pH from 2.0 to 10.0. There were no significant changes in algicidal activity by heat treatment and the pH change between pH from 5.0 to 10.0. The algicidal substances produced from Micrococcus sp. LG-5 were mainly detected in the fraction of $10,000{\~}1,000$ MWCO (molecular weight cut-off). The culture filtrate of Micrococous sp. LG-5 showed antimicrobial activity against Enterococcus faecalis, Escheiichia coli, Uebsiella pneunioniae and Vibrio altinolyticus, but did not show against Pseudomonas aeminosa, P. Buorescens, Salmonella typhi, Staphylococcus aureus, V. cholerae and V parahaemolyicus. The culture filtrate of Micrococcus sp. LG-5 was examined against 16 phytoplankton species and showed the algicidal activity against Ajexandzium tuarense, Eutreptiella Drnnastin, Gymnodinium catenatum, G. mikimotoi, G. sanguineum, eyodinium impuaicum, Heterocapsa triquetra, Heterosipa akashiwo, Prorocentrum micans and Pyraminonas sp.. However no algicidal effects of Micrococcus sp. LG-5 were observed against Chlamydomonas sp., Cylindrotheoa closterium, P. mininum, P. triestimum, Pseudonieschia sp. and Sczipuiella trochoidea. On the other hand, algicidal activity on the tested marinelivefood was not detected except for Isochrysis galbana. In addition, physiological responses of cultured olive flounder (Paralichthys oliraceus) exposed to $1 and 10{\%}$ of the culture filtrate of Micrococcus sp. LG-5 were measured. There were no clear changes in AST, GGT, creatinine, urea, total cholesterol, total protein, albumine, $Mg^(+2), Ca^(+2), Na^+, K^+, and Cl^-$. These results indicate that olive flounders were not affected when they were exposed to the culture filtrate of Micrococcus sp. LG-5.

Cloning and Characterization of Two Distinct CD3 Genes from Olive Flounder Paralichthys olivaceus
Kim, Mu-Chan,Park, Chan-Il The Korean Society of Fisheries and Aquatic Scienc 2005 Fisheries and Aquatic Sciences Vol.8 No.2
Two distinct CD3 homologue genes, $CD3\gamma/\delta\;and\;CD\varepsilon$, were isolated from a olive flounder leukocyte cDNA library and a BAC library. $CD3\gamma/\delta$ consisted of 961 bp encoding 178 amino acid residues, and $CD3\varepsilon$ consisted of 1006 bp encoding 164 amino acid residues. When compared with other known CD3 peptide sequences, the most conserved region of the two olive flounder CD3 chain peptides are the cytoplasmic domain and the least conserved are the extracellular domain. A phylogenetic analysis based on the deduced amino acid sequence grouped the two olive flounder CD3 sequences with $CD3\varepsilon$ and $CD3\gamma/\delta$, respectively. The olive flounder CD3 cluster (consisting of $CD3\varepsilon\;and\;CD3\gamma/\delta$) spans only 10.4 kb. The $CD3\varepsilon\;and\;CD3\gamma/\delta$ genes are oppositely transcribed only 3.8 kb apart. Both olive flounder CD3 genes have five exons. The two olive flounder CD3 genes were predominantly expressed in PBLs, kidney, spleen, and gills.
