Through numerical experiment using simplified OSU-ID PBL(Oregon State University One-Dimensional Planetary Boundary Layer) model and field measurement, we studied the impacts of vegetation canopy on heat island that was one of the characteristics of local climate in urban area. It was found that if the fraction of vegetation was extended by 10 percent, the maximum air temperature and the maximum ground temperature can come down about 0.9℃, 2.3℃, respectively. Even though the field measurement was done under a little unstable atmospheric condition, the canopy air temperature was lower in the daytime, and higher at night than the air and ground temperature. This result suggests that the extention of vegetation canopy can bring about more pleasant local climate by causing the oasis, the shade and the blanket effect.

As members of the special community, salt-workers have their own terms not only in professional but also in general expressions fairly different from usual expressions. In this paper, in order to investigate the origin and the derivation processes of the terms, 799 terms majorly used in the salt-works scattered in the west coast of Korea were collected and classified in accordance with the following descriptions. 1. Terms of tools and instruments 2. Terms about the unit work or unit process 3. Terms about the structure of salt-works 4. Other terms nomenclature used in salterns. 5. Terms about geography, river, soil and tide around salt-works 6. Terms about the organization of personnel 7. Adjectives 8. Verbs (Transitive Verbs) 9. Units Further investigations on the origin, processes of derivation and effects of these special terms on adjacent communities will be carried out later.

Effects of Siljangsan(實腸散) extract on the intestinal tract were studied in isolated orgna segments in vitro. Treatment of Siljansan extract caused an decrease of the contractile response of the isolated guinea pig ileum. Generally the magnitude of decrease was related to the dose of Siljangsan extract. The relaxative response of isolated guinea pig ileum induced by Siljangsan extract was inhibited if propranolol was pretreated to the ileum segment. And contractions of isolated guinea pig ileums, induced by acetylcholine, histamine and 5-hydroxytryptamine, were inhibited on Siljangsan extract. Effects of Siljangsan extract on the serum slectrolyte were also investigated in rat in vivo. Serum-Na^+ concentration, in contrast to control group, has appeared significant value in 100mg/kg(4hr), 500mg/kg(2, 4hr) administered groups. Serum-K^+ concentration, in contrast to control group, has appeared significant value in 100mg/kg(1hr) administered group. Serum-HCO^-_3 concentration, in contrast to control group, has appeared significant value in 500mg/kg(4hr) administered group. But the effects of Siljangsan were not directly relate to regulation of water and electrolyte(Na^+, K^+, HCO^-_3) The results presented in this study suggests that the therapeutic effects of Siljangsan on the intestinal tract function might due to its action on the autonomic nervous system of intestinal tract and directly on the intestinal smooth muscle.
動物筋肉中 抽出時間에 따른 Actomyosin의 生物活性 比較

Actomyosin was extracted from skeletal muscle of Cattle, Rabbit and Hen. Biological activities were compared function of animal species in one hand and the effect of EGTA on the actomyosin. The following results were obtained 1. More than 24 hours of extraction was required for the extraction of Cattle, Rabbit and Hen actomyosin, myosin was first released during the extraction followed by actin, which upon the release, formed actomyosin thus indicating a certain difference in compactness in filamental lattice and filamental integrity. 2. In the case actomyosin, 125 micro M EGTA inhibited Mg-ATPase activity indicating a common component of troponin regardless the animal species and the duration of extraction of this substance.

The measurement of gross beta activity and the concentration of ^90Sr in the vegetables such as Brassica Campestris, Raphanus Sativus and Lactuca Sativa grown in Daejeon area was carried out during the period of April through August 1983. The observed levels of gross beta activity and the concentration of ^90Sr in the leaves of the vegetables were, on average, 189.2±51.8pCi/g-ash(2372±827pCi/㎏-fresh) and 44.4±11.5 ^90Sr pCi/g-Ca(2.5±0.5 ^90Sr pCi/g-ash or 31.6±8.6 ^90Sr pCi/㎏-fresh), respectively, while the mean level of the gross beta activity in roots was 158.6±19.4pCi/g-ash(2121±899pCi/㎏-fresh). On the basis of the ICRP recommendations, an estimative evaluation was made for the concentration of ^90Sr in the vegetables, and it was turned out to be far below the permissible level. An attempt was also made to look for any existing difference in the gross beta activities of the vegetables grown in vinyl house and in open field, taking seasonal variation of airborne radioactivity into account for normalizing the activity deposited during the course of discrepant farming period.

The subjects of this study Totally there were137 old women and man aged 65 to 80. With a view to measure psychological status of old people Psychological Health Evaluation Tool" in "Tool for Evaluation of Health of Old People in Korea' which was tested for its reliability and its feasibility and developed by LEE, YOUNG-JA (1989) for the purpose of furnishing basic data to provide objective evaluation on status of health of old people in Korea was used. The tool used for evaluating psychological health consists of 23 questions covering 'subjective feeling of well-being' of old people on their life daily living and measuring them by means of interview and scoring methods which converted subjective and qualitative factors such as attitude, sentiment and emotion etc. to objective and quantitative scores. As a method of study totally two times of dance sports recreation program with 60 minutes per meeting aiming recovery of emotional functions of old people while enjoying it were performed for the old women mentioned above and by measuring their psychological status before and after such performance was compared and analyzed. Comparison of psychological status before and after conducting such dance sports was tested by subordinate and processed by SPSS V.8.0 for window. The results analyzing data are as follows: 1. The result of testing the difference in status of feeling of content for their life of old women before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting an increase of 0.4026 in average with t=7.352. 2. The result of testing the difference in pessimistic attitude for their life of old women before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting decrease of 0.2063 in average with t=5.352. 3. The result of testing the difference in feeling of happiness before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting an increase of 0.2283 in average with t=3.539. 4. The result of testing the difference in feeling of loneliness and alienation before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting a decrease of 0.3576 in average with t=6.394. 5. The result of testing the difference in feeling of well-being of old women before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting increase of 0.7975 in average with t=6.392. 6. The result of testing the difference in feeling of status of their health of old women before and after conducting dance sports showed statistically significant difference at a level of p<0.05 level reflecting increase of 0.442 in average with t=3.294. As mentioned above conducting dance sports for old women produced sense of satisfaction, happiness and optimal sense of well-being and improvement in feeling of their health while generated decline in pessimism and feeling of loneliness and alienation. For this reason it can be said that such program contributed improvement in psychological health of old women. Through this study it was impossible to confirm that dance sports has significant meaning for old people therefore there should be continuous development and extensive application of effective programs for the purpose of popularizing result of this study.
