도복 백미와 무도복 백미로부터 쌀 단백질을 추출하고 쌀 단백질과 curdlan 또는 κ-carrageenan을 일정 비율(3:0, 2:1, 1.5:1.5, 1:2, 0:3)로 혼합하여 복합 필름을 제조한 후 물리적 성질을 비교하였다. 쌀 단백질/curdlan 복합 필름의 경우 인장강도는 curdlan의 혼합비율이 증가할수록 증가하였고, 신장율은 혼합비율이 1.5:1.5일 때 가장 큰 것으로 나타났으며, 수증기투과도는 curdlan의 혼합비율이 증가할수록 감소하는 경향을 보였지만 감소폭은 크지 않았다. 도복미와 무도복미 사이에 물리적 성질의 유의차는 없었다. 쌀 단백질/κ-carrageenan 복합 필름의 경우 인장강도는 κ-carrageenan의 혼합비율이 증가할수록 증가하였고, 신장율은 감소하였다. 수증기투과도는 일정한 경향을 보이지 않았다. 또한 도복미와 무도복미로 제조한 쌀 단백질 복합 필름의 물리적 성질사이에 유의차는 없었다. This study was performed to extract rice protein from milled rice that is either lodged or unlodged, in order to prepare composite films by mixing the protein with curdlan or κ-carrageenan (3:0, 2:1, 1.5:1.5, 1:2, 0:3), and to compare the physical properties of the films. In the case of rice protein/curdlan composite films, tensile strengths increased with increasing curdlan content but water vapor permeabilities decreased, while, elongations showed a maximum at a mixing ratio of 1.5:1.5. In the case of rice protein/κ-carrageenan composite films, tensile strengths increased with increasing κ-carrageenan content but elongations decreased, while water vapor permeabilities showed no tendency. Overall, there were no significant differences in the physical properties of composite films between lodged rice and unlodged rice.

A series of 3,4-dihydro-3-oxo-2H-1,2,4-benzothiadiazine-l,l,dioxides with cytotoxic activity against human solid tumors is described. Synthesized compounds showed mild but broad spectrum cytotoxicity in vitro. The lipophilic substituents like alkyl, alkoxy and chloro on benzene ring increased the activity. Also hydrophobic group on 3 or 4 position of benzothiadiazine was important for the activity

Objectives : The purpose of this study is to investigate necessity of overtime hospital business hours and patient's visiting time preferences. Methods : The study was composed of 117 children's protectors who visited the pediatrics department in Kyunghee university oriental medicine hospital between on April 14th and on July 4th in 2008. Results and Conclusions : 1. Question for asking the preference of weekdays regular consultation hours 27% of preschool children preferred time around 11 am to 12 pm, each 32% of school aged children preferred time around 3:30 to 4:30 pm, 4:30 to 5:30 pm. 2. Question for 'Have you ever experienced inconvenience for regular consultation hours' 41% of them said 'Yes', and 59% said 'No'. 3. School aged children more experienced inconvenience for regular consultation hours than preschool children, and more likely to come at overtime hospital business hours. 4. Question for 'If the hospital extends the business hours for holidays and weekdays and Saturdays, would you prefer to come at that time?' 88% of them answered 'Yes'. 5. Question for asking the preference time on weekdays, 35% of them preferred 6:30 to 7:00 p.m. 6. Question for asking the preference time on Saturdays, 44% of them preferred 1:30 to 2:30 p.m. 7. Question for 'Do you willing to pay extra charges if you visit in non office hours?' 66% were willing to pay, 24% of them said "no", 'the other opinion' is 10%.
