School illumination with full volume of light and adequate brightness is designed to help students better focus on their education and produce an optimum atmosphere where students can apply their utmost to learning. This paper presents study on actual illumination environment of schools in order to figure out illumination problems. Furthermore, it attempts to suggest an optimum design for schoolroom illumination through computer simulation. We try to attain qualitative improvement effect in school illumination under the illuminaion plan which is based on illumination maintenance and uniformity ratio that K.S. illumination standard sets.

The aim of this study was to investigate the effect of ethanol extract of Fagopyrum escuentum(FE) on the melanogenesis. To determine whether ethanol extract of FE suppress melanin synthesis in cellular level, B16F10 melanoma cells were cultured in the presence of different concentrations of FE ethanol extract. In the present study, the author examined the effects of FE ethanol extract on cell proliferation, melanin contents, tyrosinase activity. Cell proliferation was slightly increased by treatment with ethanol extract of FE (25-200 ㎍/ml). The ethanol extract of FE effectively suppressed melanin contents at a dose of 100 ㎍/ml. It was observed that the color of cell pellets was totally whitened compared with the control. The ethanol extract of FE inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis. These results suggest that the ethanol extract of FE exerts its depigmenting effects through the suppression of tyrosinase activity. And it may be a potent depigmetation agent in hyperpigmentation condition.

We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.

The purpose of this experimental study is to study whether Onkyungtang is effective or not on preventing 24 rats were divided into 4 groups, administered physiological saline after sham operation group(sham-op. group), administered physiological saline after avariectomy group(control group), administered Onkyungtang 0.1g/100 g and gellatin 0.04g/l00g after ovariectomy group(sample A), administered Onkyungtang 0.025 g/l00 g and gellatin 0.01 g/l00g after ovariecfomy(sample B). The body weight, utetus weight, esrradiol, asteocalcin, traveculae area and iNOS area in distal ponion femur. 1. The medicine controls weight gains due to ovariosteresis 2 . Amount of estradiol in sera is not increased. 3. Due to not to be inmased quantity of ostwcalcin in sera, it is not function of osteoblast to be flourishing. 4. According to survey with a microscope, trwecdae area is remarkably increased. Thus, a group to be provided a higher degree of density increase more bony density. 5. The iNOS somewhat strongly showed with osteoblmt and osteoid tissue to all ovariosteresis groups compared to sham operation groups. As the above mentioned results, it is believed that Onkyungtatang is effective to preventing ostecpxosis.

The purpose of this study is to elucidate the effects of regular swimming exercise on blood lipoprotein metabolism and leptin. In this study, swimming(HRmax 50-75%, 60min/day, 5day/week) was performed and 18 were participated for study during 16 weeks. They were divided into two groups, one group as experimental group(n=9) and the other as control group(n=9). A measured factors were TC, TG, HDL-C, LDL-C and leptin.. All data were expressed as mean± standard deviation by using spss package program(win 9.0), one way anova and independent t-test was used to analyze the difference of exercise duration(0week, 8week, 12week, 16week) between groups. For all statistics performed statistical significance was set at p<.05. After exercise intervention, TC, TG, HDL-C, LDL-C and leptin were found to have more significant effects in the experimental group than control group. This results indicated regular swimming exercise training is beneficial to prevent and treat cardiovascular disease and obesity.
