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.

본 연구는 미성숙, 성숙 단계의 돼지 난포란이 유리화 동결에 의한 동결보존이 가능한지를 조사 하고자 실시하였다. 난포란은 세포질 내 지방구를 분극시키기 위해 원심분리를 실시하였고, 미세조작기를 이용하여 지방구를 제거하였다. 돼지 난포란을 CB 처리하여 원심분리 후 지방구를 제거한 지방제거구(Delipated), CB 처리 후 원심분리만 하여 지방구를 분극시킨 원심분리구(Centrifuged), 아무처리도 하지 않은 대조구(Control)를 EM grid

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.

국내산 ‘하파’외 4품종과 일본산 ‘Kaneko외 9품종을 2000년 8월 2일에 일반농가포장에 파종하였다. 국내산과 일본산 비교 재배하여 이 지역에 가장 적합하고 우수한 품질의 당근 품종을 선발하기 위하여 실험을 수행하였다. 초장, 엽수 및 엽중은 국내산인 경우 고정종인 ‘중앙’이 각각 60.7 cm, 9.3매, 72.9 g로 가장 우수하였고 교배종에서는 ‘부러운’이 각각 60.3 cm, 8.9매, 65.42으로 가장 우수하였다. 국내산중 근경, 근장 및 근중은 교배종, 고정종 모두에서 ‘비바리’가 52mm, 15.7cm, 275 g으로 우수하였으며 일본산인 경우 교배종은 ‘Sei’이 56 mm, 14.6 cm, 319 g으로 양호하였고 고정종은 ‘Tokai’가 가장 우수하였다. 상품수량은 국·내산에서 ‘하파’(5,472 kg/10a), 일본산은 ‘Kaneko’(5,736 kg/10a)가 가장 높았고 그 외의 품종들은 국내외산 모두 비슷한 경향을 보였다 열근의 발생율은 ‘부러운’이 15%정도로 높았고 고정종인 ‘중앙’이 10% 정도였다. 기근 발생율은 ‘Hidomi’가 9%로 가장 높았고 ‘Sei’과 ‘Tokai’순으로 각각 2%, 6%로 나타내었다. 이로 미루어 볼 때 당근의 주요 상품성을 결정하는 기근과 열근의 발생율은 국내산보다 일본산이 높아 앞으로 재배법을 좀 더 개발하면 국내산 품종이 더 제주지역의 재배에 유리할 것으로 기대되었다.

Methyl glycoside oleic acid polyester was successfully prepared from methyl glycosides and methyl oleate by emulsion interesterification in the presence of methyl fructoside oleic acid polyester as an emulsifier. Emulsion interesterification process was optimized to obtain 98% yield of methyl glycoside polyester within 3~5hr at temperatures as relatively low as 90~150℃ and 20~200mmHg pressure with a five-fold molar ratio of oleic acid methyl ester to methyl glycoside in the presence of 2(w/w)% potassium carbonate and 2O(v/v)% methyl fructoside polyester based on oleic acid methyl ester.
