  • Phytic acid content of 6 varieties of Korean barley ranged from 0.94 to 1.17%. Polishing of barleys greatly reduced the level of phytic acid. Cooking and autoclaving had little effect on phytic acid reduction, while ultrasonic treatment removed 57% of the phytic acid content. Germination decreased barley phytic acid 24% and increased phytase activity 9-fold. Phytase purified by ammonium sulfate precipitation, gel filtration and DEAE-cellulose chromatography showed an optimum pH of 5.0 and an optimum temperature of $40^{\circ}C$.

  • E. coli (K-12 W1485) was grown in M9 minimal medium containing ginseng saponin (10-3%-2%) and found that the cells grew most rapidly in the presence of 10-1% saponin. The cells, harvested at the early exponential phase, were transferred to the minimal medium containing 10-1% saponin plus 14C-labelled saponin (0.03 ${\mu}$Ci) and the incubation was continued at 37$^{\circ}C$ for 20 minutes and the cells were fractionated into the outermembrane, innermembrane and cytosol fraction. Radioactivity data showed that the most radioactivity was detected in the innermembrane. The activity of succinate dehydrogenase of the cells grown in the above saponin medium was significantly higher than that of the cells grown in ordinary minimal medium. No significant difference of the glucose 6-phosphate dehydrogenase activity was observed between the two groups. It was also found that the saponin stimulated glucose uptake and biosynthisis of lipids and proteins of the cells. Incorporation of 14C-leucine into the protein fraction of the cell was also accelerated.

  • The human scale of the interior space of a korean traditional residence is normally user-friendly. And this aspect is reinterpreted and implemented in the modern structure. While our conscious awareness has become greatly westernized through the east-west exchanges, the interior of the traditional Korean residence has always reflected the people and their daily lives of the time. In this study, an attempt has been made to identify the aesthetic characteristics of the inner space elements through the analysis of visual perception inside a Korean traditional upper class residence, kangreung Sunkyojang, designated as the 5th Cultural Information Material with regards to the inherent philosophy and human scale that influenced the emotions of the Korean people. The different parts of the interior space of Anchae, and the Symmetrical of Formal, Balance of the walls give a sense of calmness, and the ornaments are used to give gaiety. The ceiling of Yeolwhadang hall give an energetic feeling and pillare are used to enhance spaciousness. In Whalejeong, by making use of similar and continuous lines, the light and darkness was controlled and the link with nature has been emphasized. Different decorations used reflect scholarly spirit.

  • The influence of water temperature (WT) on air temperature (AT) in the eastern and western coastal regions of the Korean peninsula in the winter was investigated using historical data from the Korean Meteorological Agency (KMA) and the National Institute of Fisheries Science (NIFS), focusing on the relationship between AT and WT. The data analysis shows that, during winter, the AT is generally higher by +1.9 to $+2.7^{\circ}C$ at Kangreung ($37.2^{\circ}N$) in the eastern region than at Inchon ($37.4^{\circ}N$) in the western region, i.e., the AT in the eastern region of the Korean Peninsula tends to be higher overall than that in the western region when similar latitudes are compared. On the other hand, in the winters of 1977-2006, the WT at Sokcho was higher by $+0.8^{\circ}C$ (January) to $+2.3^{\circ}C$ (March) than that at Sochungdo, directly resulting in increased AT ($+1.22^{\circ}C$) at Sokcho. This study suggests that higher AT in the eastern region during winter is caused by the influence of water flow, such as the East Korean Warm Current in the East/Japan Sea.

  • This study was designed to compare the education needs in LBW infant's mother at discharge and after one month at home for development of the educational program. The subjects of this study consisted of 61 mothers of LBW infant's at discharge and 51 mothers of LBW infant's after one month at home. They were selected by convenience from 3 general hospitals and 1 pediatric hospital in Seoul, Kangreung and Inchon. The data were collected during the period from January, 5 to March, 15, 2000. The Education Needs for LBW infant Care was measured by Questionnaire that has developed by researchers. The data were analized by descriptive statistics, non-paired t-test & ANOVA using SAS. The results of this study were as follows: 1) The educational need, of the mothers of LBW infant at discharge were higher than the mothers of LBW infant after one month at home(t=8.72, p=.00). 2) There were significant associations between the educational needs of the mothers of LBW infant after one month at home and numbers of children(F=3.61, p=0.03). 3) There were significant associations of the educational needs between the mothers of LBW infant at discharge and the mothers of LBW infant after one month at home in categories and items. (1) There were significant associations by categories such as Infant care(t=8.34, p=.00), feeding(t=6.71, p=.00), unusual behavior (t=6.54, p=.00). Management disorder (t=8.67, p=.00), attachment between parents and infant(t=5.19, p=.00) and environment (t=6.14, p=.00). (2) There were two items that represented the highest educational needs in all items. That were "How about we can do when infant has a breathing disorder" and "How about we can do when infant has a seizure". These two items included Management of disorder category. In Conclusion, when the nurse teaching the method of infant care to mother, educational contents must be included about Management of disorder emphatically.

  • Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

  • This study presents results of surveys conducted Seoul and Kangreung public health center using structured questionnaire developed by researchers to identify factors that were relevant to the method of feeding. To compare the infant's development between the breast-fed infants and formula-fed infants, infant's height, weight, triceps skinfold during 1month and 4months were cheked. The results were as follows : 1. At postpartum, 59.1% infants had formula feeding, while 22.6% had breast feeding. At 1 month old, 49.6% infants had formula feeding, 27.8% had breast feeding. At 4 months old, 60.9% infants had formula feeding, while 26.1% had breast feeding. 2. 'Lack of breast milk' was the predominant reason for formula feeding. 3. The sujects didn't enough eat not only rice and seaweed soup but also any other specific foods during breast feeding period. 4. Factors that affected the method of feeding were the patterns of delivery, mother's height & weight, first baby feeding type(at post partum), infant sex, mother's age, preparation of breast feeding, first baby feeding type, regular clinic visit (at 4months old). 5. The birth weight and height were correlated with mother's weight and height. 6. There were no significant different on infant's weight, height, triceps skinfold between breast-fed infants and formula-fed infants.
