  • To elucidate the effect of sucrose on cell growth and anthocyanin production, 1, 3, 5, and 7% sucrose were applied to liquid MS basal medium supplemented with 0.5 mg/L BA + 0.1 and 1 mg/L 2,4-D. Higher sucrose concentration decreased the cell growth regardless of the hormonal composition. Cain in fresh weight was gradual, showing the peak at day 12 in culture, and then decreased. Anthocyanin content increased with sucrose concentration in the medium, and practically there was no difference in anthocyanin content between the two media differing in 2,4-D content. Sucrose concentration for appropriate anthocyanin production was 7%, while 5% was more suitable for increase in total anthocyanin content. At higher sucrose levels, anthocyanin content was high due to the cessation of the cell growth. Medium pH decreased at the early stage and gradually increased thereafter.

  • This study has been conducted on the nonequivalent control group Pretest-posttest design in quasi experimental basis and newly born premature infants from intensive care unit of G Medical University Hospital in Inchon Metropolitan were selected in two groups of 21 infants each. The first group for experimental and the other for control. Data has been collected form October 30, 1997 to August 29, 1998. For the experimental group tactile and kinesthetic stimulation was applied 2 times a day for 10 days(10:00~ll:00 hours in the morning and 17:00~18:00 in the afternoon). As, a weight weighing instrument, electronic indicator scale(Cas Co. korea) was used. Collected data were analyzed with the SAS program using x²-test, student t-test, repeated measures ANOVA, Pearson correlated coefficient and Stepwise multiple regression. The result were as follow. 1. As for the daily weight gain, the experimental group showed first change in weight and this group also showed higher weight in the average weight than the control group. Statistically, however. there was no significant factor between the two groups. 2. In the correlation between general characteristics and weight gain, gestation Period. apgar score, admission Period before study, N.P.O. period after birth, recovery Period to birth weight showed statistical significance negative correlation with weight gam in the experimental group than control group. 3. In the factor with affected the weight gain by general characteristics showed recovery period to birth weight and head circumference in the experimental group, control group showed recovery period to birth weight, N. P. O. period after birth. admission period before study, feeding amount, weight of study. In conclusion. the sensory stimulation in this study showed a Positive aspect through there was no statistical significance in the weight gam. Tn the correlation of general characteristics and weight gam showed statistical significance negative correlation The main factor which affected the weight gain by general characteristics showed recover period to birth weight.

  • The stability of urban railway foundation can be a problem due to the excessive settlement. The settlement at the base of railway is monitored by the installed settlement gauges. The piezometer and pore water pressure measurement device are installed to measure the variation of pore water pressure and ground water table during the continuous pullout of sheet piles which were used for the braced cut. The settlement of railway is predicted with using the computer program CAIN RDA. The input data for the numerical analysis are obtained from the field soil exploration data and soil properties. The surcharged load from landscaping over the ground surface and the weight of train are taken into account for the estimation of settlement. As a result of numerical analysis, the range of settlement for six different Sites is from 5.94 cm to 12.77 cm. Thus, the settlement level at Site 2 is occurred 12.77 cm which is higher than the allowable settlement of 10 cm.
