In the country, already a 400 species and some Interchanges of different Section of Industry have been organized and a number of related industry come to a 4000 species. But in the present, Interchanges of different Section of Industry stay at a form of a friendly society as yet. In this study, we will be helpful to activity of Interchanges of different Section of Industry by concretely suggestion of the utility operation method of Interchanges of different Section of Industry in the many-sided point.

본 연구는 미경산돈의 첫 발정과 종부시 품종에 따른 체중, 연령, 체장, 체고, 흉위, 등지방 두께, estradiol-l7β, cortisol 그리고 progesterone 농도에 미치는 영향을 조사하여 앞으로 돼지 번식능력 향상을 위한 기초자료를 제공하고자 실시하였다. 본 연구에 공시된 듀록, 랜드레이스, 요크셔 미경산돈은 충남축산위생 연구소 산하 축산시험장에서 2000년부터 2002년까지 생산한 자돈을 선발하고 육성하여 이용하였다 미경산돈의 첫 발정과 종부시 듀록종이 랜드레이스종이나 요크셔종 보다 체중이 더 무거웠고 연령이 많았으며, 흉위도 컸다. 첫 발정과 종부시 체장은 품종간에 차이가 없었고, 체고는 듀록종과 요크셔종이 랜드레이스종에 비하여 높았다. 첫 발정시 등지방 두께는 요크셔종, 듀록종 그리고 랜드레이스종 순으로 얇았으며, 첫 종부시에는 차이가 없었다. 미경산돈의 첫발정시 혈청 estradiol-l7β의 농도는 랜드레이스종이 45.0 pg/ml로 요크셔종의 27.4pg/ml 이나 듀록종의 21.8 pg/ml 보다 높았으나 첫 종부시에는 18.5-31.9 pg/ml로 품종간에 차이가 없었다. 혈청 cortisol의 농도는 첫 발정과 종부시 듀록종이 랜드레이스종이나 요크셔종에 비하여 높게 나타나 품종간에 차이를 나타내었다. 혈청 progesterone의 농도는 첫 발정과 종부시 품종간에 차이가 없었다.

We studied electrochemical characteristics of Langmuir-Blodgett(LB) films by using cyclic voltammetry with a three-electrode system. An Ag/AgCl as a reference electrode, a platinum wire as a counter electrode and LB film-coated indium tin oxide(ITO) as a working electrode were used to study electrochemical characteristics at a various concentration of NaClO4 solution. LB films were reduced from initial potential to -1350 mV, continuously oxidized to l650mV and returned to the initial point. The scan rate was l00mV/s. The monolayer surface morphology of the LB film have been measured by Atomic Force Microscope(AFM). As a result, We comfirmed that the microscopic properties of LB film by AFM showed the good orientation of momolayer molecules and the thickness of monolayer was 3.5-4.lnm. The cyclic voltammograms(CV) of the ITO-coated glass showed the peak potentials for the reduction-oxidation reation. LB films of 4-octyl-4'-(5-carboxypentamethyleneoxy) azobenzene(8A5H) / L-α-phosphayidyl choline, dilauroyl(DLPC) seemed to be irreversible process caused by only the oxidation current from the cyclic voltammogram. The current of oxidatation increased at cyclic voltammogram by increasing 8A5H density in LB films. The diffusivity(D) of LB films increased with increasing of a 8A5H amount and was inversely proportional to the concentration of NaClO4 solution.

This study was carried on the oxidative stability and the real practice possibilities in cooking of fat replacer MCT. Nowadays, it was known that fats and oils had become causes for cardiac disease, obesity and cancer, so the new materials were needed for fat substitute that has less fat contents and low calories. The food industry concerned about fats and oils had been researched and developed new and various kinds of substitute fats. MCT(medium chain triglycerides) is one of the fat based fat substitutes used as fat replacers. The POV of com germ oil(CO), soybean oil(SO), shortening(ST), butter(BT), their blended oil with MCT 10-50%(w/w), and MCT were determined and oxidative stability by POV was compared MCT with those of them. MCT has shown higher oxidative stability than CO, SO, ST, BT, so oxidative stabilities in all kinds of blended oils become higher and higher by the increased substitution ratios. In case of bread, the volume of bread prepared with MCT(MCT bread) substituted for ST at 10-40% level(w/w) were increased a little comparing to that made of shortening(ST bread). But degree of gelatinization of MCT bread were a little lower than ST bread, at the substitute ratio above 40%, the degree of gelatinization were reduced greatly. These phenomena were sustained in 9 stored days. While baking losses of MCT breads were almost same as ST bread until 30% substitute ratio, and the appearances of MCT breads were similar to ST bread until 40% substitute ratio. Also rheological properties and color(Lab) of MCT breads had shown no different significantly from ST bread until 20% substitute ratio, but by the results of sensory evaluation, overall acceptance including appearance, color, flavor, taste, texture of MCT breads were recognized almost same as ST bread by panel until 40% substitute ratio. Depends on the above results, we can suggest that 30-40% of MCT will substitute for shortening in making bread in order to reduce fat and calories intake amounts.

이 연구는 일본 중서부 지방에서 1996년 겨울철에 발생한 뇌우의 관측 자료를 분석한 것이다. 관측기간 중 35 회의 뇌우가 발생하였으며 발생된 뇌 방전 수는 4426개였다. 관측된 뇌 방전 수를 뇌 방전 종별로 구분하여 그 발생비율을 구하였고, 뇌 방전의 종류와 기압배치와의 관계도 분석하였다. 그 결과 구름 뇌 방전의 비율은 약 78%이었으며, 양극성 낙뢰가 42.3%로 나타났다. 동계의 낙뢰활동은 미약하나 0∼5시에 가장 강하였다. 또한, 낙뢰는 북서 계절풍이 강한 경우에 활발하게 발생되고 있음을 알 수 있었다. 다중뇌와 다지점 낙뢰의 분석결과 평균 다중도는 1.4이고, 평균 다지점 낙뢰는 1.2로 나타났다.

This study is to analyze spatial structure of Eupchi(邑治) on Chungchong province with Chungchong-do regional maps(忠淸道地方地圖) and Eupjis(邑治) being compiled in the late Chosun dynasty. According to the analysis of it in this study, we make conclusions a follows; 1. Gunhyeon(郡縣) which had been Eupseong(邑城) on Changchong-do in Chosun dynasty was 13 provinces, and the construction of Eupseong was the coast Eupseong built for the purpose of defense and military Eusaeong built at Byeongyeong(兵營) and Geojin(巨鎭). And a measure used in the construction of a castle was Pobaekcheok(布帛尺) used to survey a frontier defence in Chosun dynasty, also Jucheok(周尺) or Yeongjocheok(營造尺) could be assumed to be wide use at that time. 2. Eupchi of Chungchong-do Gungyeon was almost disposed to the south direction. also had been Jinsan(鎭山) safeguarding it. With relation to Jwahyang(坐向) and Jinsan, its Jinsan and Myeongdang-cheon(明堂川) match each other in location of Eupchi, as it get Jinsan sat, and take main river in front of it. And provincial government office to be the center of a Eupchi is organized into Gaeksa(客舍), Dongheon(東軒), Naea(內衙), Hyangcheong(鄕廳), and practical business facilities, Jakcheong(作聽) or Jangcheong etc, the others is composed for the use of support of those. 3. In most Eupchi in Chougchong province, the layout Sajikdan(社稷壇) and Yeodan(?壇) was gone with a principle as they were disposed in the west and the north with Eupchi province. Jangsi(場市) of Eupchi was opened in front of government office of Gaeksa, and the Gunhyeon which had Eupseong was established in the inside and outside of Eupseong.

Fatty polyamide that gives softness, lubrication and bulky property and alkyl imidazoline that gives durable softness and antistatic property were synthesized. then, an O/W-type durable softener (DSN) was prepared by the emulsion of the synthesized fatty polyamide and alkyl imidazoline. Emulsion stability of the DSN was good, and the mixed HLB value was 11.2. From the measurement of softness, lubrication, antistatic property, bending resistance, and color fastness, it was proved that the prepared DSN was a good durable softener for nylon.

Recently there have been growing disputes between neighboring local governments over jurisdictional rights or property rights of ocean resources in Korean coastal waters. The reasons for the disputes come mainly from the increasing interests by local governments that begin to see the oceans as the source of resources and wealth. The maritime dispute is more complicated and sticky than the inland ones, and requires not only socio-economical but political approach, therefore sometimes demanding a plenty of time and endeavor. Also coastal states that have suffered from maritime boundary problems have different issues under the different environment and historical background. For Korea, as the maritime boundary issue has very recently soared to the surface, though it was latent for the period as long as 20 years, we have just taken steps toward an institutional approach on it, seemingly more to go to reach an agreeable resolutions to the disputes. This paper highlighted the issues surrounding the maritime boundary on the sea surrounding Korean peninsular after addressing the current situation of the boundary disputes. It will help explore and assess the possible solutions to the boundary conflicts over the lateral boundary between local governments.
