폴리스티렌과 싸이클로헥산 용액으로부터 제조된 멤브레인의 미세구조 형성에 미치는 coarsening의 효과를 주사전자현미경(SEM)을 이용하여 연구하였다. 고분자 용액의 열 분석은 DSC를 이용하여 행하여졌으며 demixing peak의 개시 온도로부터 binodal 곡선이 결정되었다. 열적으로 유도된 상 분리(TIPS) 공정과 freeze drying 기법을 이용하여 제조된 고분자 막의 미세 구조는 coarsening 시간과 quench 경로에 의해 큰 영향을 받음이 확인되었다. Spinodal decomposition이 상 분리 기구인 경우에는 멤브레인의 미세구조가 서로 잘 연결되고 거의 일정한 cell 크기를 갖게 되며, 용매를 제거하기 이전에 상 분리 시간을 증가시킴으로써 멤브레인의 pore 크기를 증가시킬 수 있음이 판명되었다. 또한 멤브레인의 cell 또는 pore 크기 증가는 coarsening time과 quench depth에 크게 의존함이 확인되었다. 본 연구에서는 특히 고분자 용액의 농도가 이로부터 제조되는 고분자 막의 구조에 미치는 역할을 규명하였다.

This study aims at classifying and analyzing the vegetation structure of Castanopsis sieboldii forest, one of the evergreen broad-leaved forests found under the warm-temperate climate of Korea. It is also compared with the ones of the Castanopsis sieboldii forest in Japan where most similar such forest of Korea, to find unique vegetation structures of the only Korean forest. Vegetation structure of Korean Castanopsis sieboldii forest was divided into two units at the level of community units both of Ardisia japonica-Castanopsis sieboldii community and Ardisio-Castanopsietum sieboldii association. The association carries similar type with the vegetation system of Japan, but any subunits differentiated with the Japan were found vary much. Hierarchical cluster analysis brings in similar result with the analysis on the vegetation structure as well.

A new deep red colored standard rose (Rosa hybrida Hort.) cultivar, `Best Red' was developed at the Jeollanamdo Agricultural Research and Extention Services (JARES). Seedling and line selection were conducted in 2003 and its characteristics were examined three times from 2004 to 2006. 'Best Red' which was obtained by cross between 'Vital' and 'Cardinal'. It shows a red group color (RHS No. 46C), medium fragrance, and standard flower with good harmony between ray floret and flower center. The upper stem is moderate curved. The average yield during 2004-2006 was 111 stems/m2. Its vase life was 10 days. This cultivar was registered as a commercial cultivar in 2007. It is suitable for greenhouses in all regions in Korea and will be released to farmers in 2009.

A new pale pink colored standard rose (Rosa hybrida Hort.) cultivar, 'Fine Pink' was developed at the Jeollanamdo Agricultural Research and Extention Services (JARES). Seedling and line selection were conducted in 2003 and its characteristics were examined three times from 2004 to 2006. 'Fine Pink' was obtained by crosse between 'Nobless' and 'Yvessaaintlaurent'. It shows a red group color (RHS No. 56C), very weak fragrance, and standard flower with good harmony between ray floret and flower center. It has a characteristic of straight stem. The average yield during 2004-2006 was 113 stems/m2. It has 10 days vase life and resistance to powdery mildew. This cultivar was registered as a commercial cultivar in 2007. It is suitable for greenhouse in all regions in Korea and will be released to farmers in 2009.

A new light pink colored standard rose (Rosa hybrida Hort.) cultivar, 'Top Pink' was developed by the cross between 'Nobless' and 'Belami' at the Jeollanamdo Agricultural Research and Extention Services (JARES) through seedling and line selection in 2003, and characteristic evaluation during 2004-2006. 'Top Pink' shows a Red group color (RHS No. 49A), strong fragrance, and standard flower with good harmony between ray florlet and flower center, and straight stem. The yield was 131 stems/m2 averaged over three years (2004-2007). It showed 10 days vase life and was resistant to powdery mildew. This cultivar was registered as a commercial cultivar in 2007. It can be cultured in greenhouses in Korea and will be released to farmers in 2009.

A new dark pink colored standard rose (Rosa hybrida Hort.) cultivar, 'Global Pink' was developed by the cross between 'Nobless' and `Belami' at the Jeollanamdo Agricultural Research and Extention Services (JARES) through seedling and line selection in 2003 and characteristic evaluations during 2004~2006. 'Global Pink' showed Red purple group color (RHS No. 65B), very weak fragrance, and standard flower with good harmony between ray florlet and flower center. Its yield was 134 stems/m2 averaged over three years (2004-2007). It showed 10 days vase life and was resistant to powdery mildew. This cultivar was registered as a commercial cultivar in 2007. It can be cultured in greenhouses in Korea and will be released to the farmers in 2009.

A new white colored spray rose (Rosa hybrida Hort.) cultivar Danmi was developed at the Jeollanamdo AgriculturalResearch and Extention Services (JARES) after seedling and line selection in 2002, and its characteristics were examined twicefrom 2004 to 2005

Effects of acute anoxia on carbohydrate hydrolytic enzyme activities and free amino acid contents in malt were examined. Malts were prepared with barley grains germinated for 7 days which contained the highest levels of amylolytic and(1-3,1-4)-β -glucanase activities. α -Amylase and β -amylase activities in malts were not significantly affected by anoxia for 5 or 10 h.(1-3,1-4)-β -Glucanase activity, however, decreased about 7 to 10% by anoxia for 5 or 10 h. Alanine and ~gamma -aminobutyric acid content changed drastically. Alanine contents in malts increased by 2.2- and 2-fold, and ~gamma -aminobutyric acid contents by 1.4- and 1.9-fold under anoxia for 5 and 10 h, respectively.
