Recently, number of elementary school students in the rural area have decreased due to move of population to the diminishment of birth population, the generation of idle facilities and even the trend of abolition of school presented problems. This paper was a study of the use plans and generation pattern of idle facilities in present school. And the targeted schools of this study were elementary schools located at Hae-Nam Province in Chun-Nam. The results are as follows : 1) While the number of the elementary school is continuosuly decreased up to now since 1980, the number of branch schools and closed schools is increasing and while general class is decreased continuously, multiple classes are increasing and so the utilization of idle facilities will be continued. 2) The utilization of idle facilities is most frequent in the use of school curriculm(67%), followed by the use of club activities and welfare facilities, but the use by residents is minimum. In the problems in using idle facilities, the lack of finance is most(68%), followed by the lack of illustrative data and technical problems and in the effects of using idle facilities, extra curriculum activities are best and followed by the use of local community and school curriculum. 3) In the most required facilities in using idle facilities, gymnasium and service area are highest and followed by laboratory, learning data room and library and in the common facilities with local residents, swimming pool is most frequent and followed by library.

In this study, velocity and temperature profiles are calculated on the apartment complex at Dunsan area in Taejon using FLUENT code based on computational fluid dynamics (CFD). Input weather conditions which maximum atmospheric is 38.6℃, wind speed is 1.7m/sec, wind direction is west-south-west and maximum wall of apartment is 58.0℃ in summer are used to calculate the results. The simulation results are as follow ; First. velocity vectors at vertical cross section of apartment complex are influenced by the thermal buoyancy force in hot wall of apartment due to weak wind speed in the case of wind direction : west-south-west, south-west, west. Second, temperature profiles at vertical cross section of apartment complex are strongly influenced by the wind direction. Atmospheric temperature in wide area is higher 1℃ in south-west wind direction than west wind direction. Calculation results show that island in enormous apartment complex in summer. Third, temperature profiles at horizontal cross section of apartment complex present wider and more definite high temperature area than at vertical cross section of apartment complex according to wind direction. This consequence shows the effect of convective heat transfer in the rear heated wall of apartment is dominant by solar radiation. Fourth, It is necessary that an arrangement of apartments with a view of wind direction and distance of each apartments to reduce heat island in apartment and industrial factory complex in the condition of same apartment direction and area capacity. And an arrangement of apartments considering wind direction is able to enhance convective heat transfer between heated wall and wind.

沈英燮,金起星,趙台淳 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.1

In this experiment, the effect of ranitidine which is histamine H_2-recepter antagonist, were studied in aspect of the relationship between acetylcholine and histamine in isolated duodenum strips of guinea-pig. At the same time, the effect of the inhibition on the acethylcholinesterase activity in human serum were examined and the experimental results was summerized as following. 1) Ranitidine showed the synergistic effect with acetylcholine in the isolated duodenum strip and this effect was blocked by atropine. However, both physostigmine and DFP induced the synergistic effect with ranitidine. 2) Ranitidine potentiated the contractability of DMPP while a little effect on the contraction response due to pilocarpine, serotonin, tetragastrin and PGF_2α in the isolated duodenum strip. 3) Clonidine showed the inhibitory effect of histamine and acetylcholine contraction response of the strip but ranitidine and cimetidine showed no effects on this preparation. 4) ID_50 of ranitidine and cimetidine on serum acetylcholinesterase was 4 x 10 exp(-4)M and 9 x 10 exp(-3)M, respectively. From the above results it was suggusted that ranitidine might have cholinergic effect in guinea-pig duodenum strips and this effect partially might be due to the cholinesterase inhibition.
