‘금촌조생’ 품종은 농촌진흥청 원예연구소 나주배연구소에서 1971년 ‘금촌추’의 품질을 개선하기 위해 당도가 높고 육질이 유연한 ‘단배’를 교배하여 1982년 1차 선발되었고, 1997년부터 5년 간 지역적응시험을 거쳐 2001년 최종 선발 및 품종보호출원 되었다. 수세는 비교적 강하고, 수자는 반개장성이다. 꽃가루가 풍부하며, 주요 재배품종과 교배친화성을 보인다. 또한 흑반병에 대하여 강한 포장저항성을 나타내었다. 숙기는 재배중인 ‘원황’ 품종보다 약 5일 정도 늦은 9월 3일로 추석에 출하하기 알맞은 품종이다. 과형은 ‘금촌추’와 같은 도원추형이고, 과피색은 황갈색이다. 과중은 593g이고, 당도는 13.2Bx이다. 육질은 유연하며 과즙이 풍부하고, 석세포가 없어 식미가 매우 우수하다. 그러나 과육선숙형 품종으로 원예적 수확기에도 과피에 녹색이 남지만, 완숙과가 되면 황갈색으로 착색된다. 상온저장 기간은 20일 정도로 다른 조생종에 비해 저장력은 좋은 편이다. ‘Geumchonjosaeng’ pear cultivar (Pyrus pyrifolia var. culta Nakai) originated from the cross between ‘Imamuraaki’ and ‘Danbae’ to improve the fruit quality of ‘Imamuraaki’ cultivar in 1971 at Naju Pear Research Institute of National Horticultural Research Institute (NHRI), Rural Development Administration (RDA). It was preliminarily selected in 1982 and named in 2001. The tree habit shows vigorous growth and upright spreading. It carries abundant pollen grains and shows cross compatibility with leading cultivars. Also it shows high resistance to black leaf spot (Alternaria kikuchiana) in the field condition. Optimum harvest time is around Sep. 3, which is 5 days later than that of ‘Wonwhang’, and it could satisfy consumer’s demand for high quality pear fruit in “Chuseok”. The obovate fruit shape resembles maternal parent, ‘Imamuraaki’ and skin color is green yellowish brown at normal harvesting time and gradually turned to yellowish brown at full ripennig state. Fruit weighs about 593 g, and the soluble solid content is 13.5 ˚Bx. The flesh is very soft and juicy and, rendering good eating quality. Shelf life is about 20 days under the ambient temperature, and it is a relatively long period as compare with other early season cultivars.

Though the pride of creating the regime by a region may offset the past material and economic alienation, the direction of national policy by new regime toward democratization directs to exterminate the regional emotion which is the absolute obstacle of national unity and reunify the South and North Koreas. Therefore this study investigates the cause of regional conflicts and regional emotion between west and east regions and examines the actual necessity of sports for the social unity before seeking the methods to exterminate the regional emotion with sports First, it grasps the type and cause of regional conflicts by examining and researching the existing research theses and literatures, carries out the questionnaire with the content, Can sports exterminate the regional emotion, with the university students in Pusan-Kyungnam region and Kwangju-Chonnam region and then obtains the following conclusions with the possibility to exterminate the regional emotion by sports. 1. The types of typical conflicts in Korea are labor-management conflict, income classes conflict, sexual conflict, generation conflict and regional conflict and the most serious social problem among these is the regional conflict. 2. The regional emotion means that the regional consciousness which is hope and desire for local community and a kind of condensed social energy shown in the relation to other regions are expressed to the people of other regions in exclusive and unfair way. 3. The use of sports can be the effective means to exterminate. In this case, the sports game of regular exchange type between amateurs not by pros can double its effects.

Concentrated solution was prepared for a sol-gel process of BaTiO₃. Barium hydroxide and Ti-isopropoxide were used as the raw materials with methanol and isopropanol as solvents. Dense ferroelectric polycrystalline BaTiO₃thin films with the perovskite structure were fabricated by spin coating of the prepared concentrated solution on a few substrates. From XRD investigation, it was confirmed that tetragonal phase of polycrystalline BaTiO₃powders are formed after heat treatment above 550℃ in air and grain-oriented BaTiO₃thin films are obtained by coating of 0.06M concentrated solution on the substrates. It was observed that surfaces of thin films deposited on the substrates by our methods were formed crack-free and uniformly. The thickness of thin film which depends the concentration of the solution was 400∼900Å for 1 time coating, which was confirmed by SEM analysis. Ceramics and thin films show dielectric constant of 4600 (at 1㎑) and capacitance 300∼800㎊ (at 1㎑) at room temperature, respectively.
