This study was performed to provide basic physiological activities data to predict the usefulness of olive leaves as a food material. Total flavonoid and total phenol contents of 80% ethanol extract of olive leaf were 5.81% and 14.8%, respectively. Total flavonoid and total phenol contents were markedly higher in butanol and ethyl acetate fractions than in hexane, chloroform, and water fractions (p〈0.05). Oleuropein in olive leaf was the major phenolic compound. The oleuropein contents of 80% ethanol extract, butanol and ethyl acetate fractions of olive leaf were 102.11±0.02, 173.35±0.03 and 152.71±0.03㎎/100g, respectively. The 80% ethanol extract, butanol and ethyl acetate fractions of olive leaf showed a growth inhibitory effect to Bacillus cereus, Staphylococcus aureus, Escherichia coli, and Salmonella enteritidis, whereas antimicrobial activities of hexane and chloroform fractions were not observed. The inhibitory activity to ACE was determined to be very weekly positive in 80% ethanol extract and all fractions of olive leaf. The nitrite-scavenging ability of 80% ethanol extract, butanol and ethyl acetate fractions of olive leaf were 72.8%, 76.0% and 75.4%, respectively. Significant evidence was detected that the butanol and ethyl acetate fractions showed higher activity than that of hexane, chloroform, and water fractions(p〈0.05).

千玉煥,崔道熙 건국대학교 1976 學術誌 Vol.20 No.1

The subject of National Ethics has been lectured at a college for 6 years so far since the establishment of the subject in 1970. Although there have been several studies on education of this subject so far, most of such studies were made on how to teach the subject. The major purpose of this study is to fulfill effects of the education of this subject in future by measuring views of the value of current college students and effect of the education which were given to them. The questionaires were given to 3,000 college students of 15 colleges and universities all over the country, and 2,259 replies were collected. The contents of the questionaires consist of six parts : human understanding, value, nation democracy, criticism on communism and the method of education. 92.8% of the college students think that human has special feature, that is, reason, which discriminates from other animal in human understanding. This shows that most of the college students have traditional and classic understanding on human being. In view of value, they show comparatively great cliffs between actual life and ideal thinking. That is, there is considerable distance between actual conduct and decision on good or bad. In the investigation on this field, approximately 70% of the students indicated approbation on the view of traditional value and 15% of the students have modern scientific view which has been cultivated recently in this country. In view on nation, 37% of the students have optimastic views and 16% have pessmistic view; the students who are proud of traditions and culture of the native country are 23% and 16% of the students feel shame, and it seems that optimistic view has gradually been increased in the view on national progress. In connection with democracy, some of the students acknowledge the principle of democracy as ideal, but 72% of the students are agreeable for the necessity of the revised democracy in Korea according to the realistic situation. In criticism on communism, the students who oppose to the communism without any reservation were 37% and 58% acknowledge the theory of communism favorable but oppose it only because of the communist system is not desirable. This shows that much more emphasis should be given on theoretical criticism in future education. Regarding method of education, two kinds of method, types of lecture and seminar, have been applied, but 78% of the students request for the type of seminar instead of the lecture type for the educational method of National Ethics.

장진환,차옥선 漢陽大學校 韓國生活科學硏究所 1992 韓國 生活 科學 硏究 Vol.- No.10

As commercial Band stockings are one of the high-demanded feminine clothes and agree on the consumer's wearing aim to express the beautiful legs. This study examined on stocking-wearing and a physical ability with three subjects of more or less different sizes to contribute to improving quality by studying the elements which spoil the external appearance in wearing stockings in consideration of the adaptation rate of human body. The results are as follows. Because stockings were circular in shape their elongation in static pose depended on the shape of subjects' legs, and each elongation of the samples was against of the size : Multi > Support > Mono. In the variation of stockings in active, the order of bandloosement on the femoral region : Multi > Support > Mono and subject A < subject C < subject B. And in transformation rate of knee's motion the order of that was Mono > Multi > support, while in Mono and Multi the order was subject B < subject A < subject C and in support stockings that was subject A < subject B < sujbect C. In the transformation rate of ankle's motion, the orders were Multi < Support < Mono and subject A < subject B < subject C. The stocking-crossing in repeated action revealed fewer in the curse direction than in the wale. The orders of course direction-crossing were Mono > Multi > Support and subject A > subject B > subject C. The orders of wale direction crossing were subject B > subject A > subject C on the knees and subject A > subject B > subject C and Mono > Multi > Support on the front of ankles-the crossing on the front of ankles was lower than one on the back of ankles. The elongation of stockings was higher in the course direction than in the wale and the order of that was usually welt < leg < band, but the orders were Multi > Support > Mono on the legs and Mono > Support > Multi on the band. The rate of elastic recovery of elongation was higher in the wale direction than in the course and the order of each sample was Support > Mono > Multi. The orders of the Snag rate were Support(4.5grade) < Mono(2grade) < Multi(1.5grade) in normal state, and Support(5 grade) < Mono. Multi(4 grade) in double stretch. Finally the loosement, crossing, Snag and so on which spoil the external appearance depend on size and materials of the stockings. Therefore, my opinion is that the range of consumers'selecting stocking-size must be wide and varied, and the studies must be achieved about the shape and each elongation of stockings and the elastic recovery.

The aim of this study was to evaluate the effect of various polymerization techniques on the microleakage of compomer restorations. Fifty extracted human premolar and molar were used and randomly divided into 5 groups. After cavity preparation, compomer (F2000) was filled according to the manufacturer's directions. All groups, except group 5, were filled using an incremental technique. Group 1was polymerized for 40 seconds at a continuous 485mW/㎠ with a VIP (Bisco, USA) light cure unit. Group 2 was polymerized for 20 seconds at a continuous 345mW/㎠ and then for 20 seconds at 645mW/㎠ with the VIP light cure unit. Group 3 was polymerized at 400mW/㎠, gradually increased to 50mW/㎠ per 10 seconds until 550mW/㎠ was reached; total 40 seconds with a Spectrum 800 (Dentsply Caulk, USA) light cure unit. Group 4 was polymerized for for 3 seconds using an incremental technique with a Flipo (LOKKi, France) light cure unit. Group 5 was polymerized for 3 seconds using a bulk fill technique with the Flipo light cure unit. The specimens were embedded with acrylic resin, and were sectioned with diamond saws in a mesiodistal direction along the longitudinal axis of the tooth so as to pass through the center of the restoration, and three surfaces (occlusal, pulpal, and gingival) were examined with SEM. The results were as follows; 1. Group 5 showed a significantly larger gaps compared to other groups on the gingival, occlusal, and pulpal walls. 2. All groups except group 5 had no statistically significant gap on the gingival, occlusal, and pulpal walls. 3. There was no significant correlation between the amount of enamel on the gingival and occlusal walls and polymerization shrinkage.

This study aims at understanding the trend of researches carried out on the subject of rooftop afforestation. The issue of rooftop afforestation is receiving attention as one of the plans to secure green zones in urban area. While the actual execution of rooftop afforestation in Korea in only in the initial state, thus in not activated, studies on this subject have been actively carried out particularly in terms of the methods of rooftop afforestation. Recently, studies are being actively performed on the creation and effect of rooftop afforestation. However, these studies tend to focus on specific areas. This leads to the necessity to approach the issue of rooftop afforestation with a wider perspective. Therefore, in the study, the previous studies on rooftop afforestation carried out both in and outside the country are categorized as the study on the methods, effect and activation plans of rooftop afforestation, thus are examined to understand the recent trend in the study of rooftop afforestation. The results indicate that domestic studies. which was centered on the methods to promote rooftop afforestation. have been expanding into the study on the methods to establish eco-habit at on rooftop as well as on the environmental and economic effect rooftop afforestation.
