Research on unused energy continues due to the limits of fossil fuel and the destruction of the environment. Therefore this study was performed as follows. The collectable amount of exhausted heat for an air-conditioning was calculated by the subway thermal environment prediction program. And the electric power needed by conventional heat source equipment was compared with one by unused heat source equipment when the exhausted heat was used by heat pump in heating and hot water supply. The results are summarized as follows 1. Forced ventilation should be conducted to keep optimal temperature in the subway tunnel in summer as well as in winter. According to the simulation, the temperature in tunnel was higher than that on the ground in summer when the forced ventilation was conducted only in the winter. 2. Ventilating time should be calculated out to the optimal condition for not only the saving power of the ventilation fan but reusing exhausted heat. By the simulation, it is certain that the exhausted heat should be eliminated in air-conditioning time. 3. The use of the exhausted heat source heat pump could save 8% of electric power per hour in comparison with existing heat pump. This was based on a present heat generation and traffic for ventilating time of general air-conditioning, but could be different by ventilating time. 4. As the traffic increases up to 1.5 or 2 times, electric power consumption of the conventional heat pump increases to 11% or 13.5% per mean hour in comparison with that of the exhausted heat source heat pump, though all-day ventilation.

In order to achieve such an objective, the following factors will be closely examined. Firstly, the difference between the participation in domestic sports and the satisfaction levels of leisure is to be discussed according to the demographic characteristics. Secondly, the difference between the satisfaction levels of leisure is to be discussed according to the participation level of university students in domestic sports. Thirdly, the relationship between the participation level of university students in domestic sports and the levels of leisure is to be clearly discussed. According to that, this research focuses mainly on teams formed by male and female undergraduates from the four-year universities located in Chuncheon-city, Kangwon-do. Using a method of simple random sampling, a total of 150 students have been selected as sample groups for those who participate in sports-related clubs and domestic physical programs. Also, a total of 150 students, with the same method of selection as before, have been selected as sample groups for those who do not participate in domestic sports. As a result, a total of 300 students have been selected as sample groups. The instruments of gathering information for this research include the leisure satisfaction scale(LSS) developed by Beard and Ragheb(1980) and adapted by Lee, Jong-kil(1992). The levels of confidence and propriety for this research have been verified by questionnaires prepared by the instruments. The level of confidence for the questionnaires has shown a result of Cronbach α = .689~.894, regarded as being extremely high. Methods of correlation, one-way ANOVA and t-test have been used with SPSS Windows 10.0 Version, in order to investigate the relationship between university students' participation in domestic sports and satisfaction levels of leisure. For the post-examination, a method of Scheffe' test has been used at a significant level of 5%. The following results have been obtained from the analysis of gathered information according to the objective of this research. Firstly, among the special demographic factors of university students who participate in domestic sports, there are significant differences for the satisfaction levels among grades, household profits, health levels and credits. However, there is no significant difference between genders. Secondly, the university students who participate in domestic sports show high levels of leisure satisfaction, compared to those who do not. Thirdly, the participation level of university students in domestic sports contributes to the level of leisure satisfaction.

Spiders are easily distinguished from all other creatures by behavior of making webs. Among the web building spiders which depend largely on their webs to predation, Atypidae, four species in Korea, uses the purse web which is the most primitive one than other spider`s web in Korea. To analyze the chemical properties of the purse web, 30 ㎎ of Atypus coreanus` web was collected in Joan-myun, Namyangjoo-city, Kyunggi-do. As a result, the purse web of Atypus coreanus mostly consists of Glycine (5.3%), Glutamic acid (8. 26%) and Alanine (14. 17%). Especially the web of Atypus coreanus has more proportion of serine (9.28%), which plays an important role in intricacy, than that of orb webs used by Nephila clavata(4.84%) and Araneus ventricosus(4.84%).

김보혜,손흥규,이종갑 大韓小兒齒科學會 1992 大韓小兒齒科學會誌 Vol.19 No.2

Discoloration of teeth, especially maxillary incisor, that appears in various types and severties causes a major problem in esthetic aspect. The attributing factors can be classified into extrinsic and intrinsic factors : chewing tabacco, coffee, and tea are some example of the former, and intake of tetracycline, fluorosis, pulpal necrosis, iatrogenic agents, systemic condition, genetic factors, and aging process are, the latter. Treatment of a discolored vital tooth include full crown restoration, direct or indirect venner restoration, vital bleaching, and so on. Several vital bleaching techniques have been developed since Capple first introduced a bleaching case using oxalic acid in 1877. Nowadays, the technique that utilizes both hydrogen peroxide and bleaching light is most preferred. The pulpal effect of vital bleaching medicaments and lights have been controversal, but it has been also noted that 98℉~141℉, 30~35% hydrogen peroxide causes only mild reversible inflammation. In these cases, 12 and 10-year-old sisters showed generalized brown discoloration of teeth. Their primary dentitions were normal color, and there were no history of discolored teeth. The exact cause could not be found, but tooth color was improved by vital bleaching of four times. For the better esthetic results, combination therapy of repeated bleaching and veneering restoration is recommended.

Aluminum-doped amorphous silicon carbide films were prepared by RF co-sputtering of SiC and Al-doped Sic. Auger electron spectroscopy(AES) and X-ray photoelectron spectroscopy(XPS) were used to determine composition of the resultant films. XPS results showed that concentration of aluminum around 1.0 atm % was achieved. Electrical conductivity was measured for a temperature range of 150 to 400K and subjected to Mott analysis. Conductivity of Al-doped a-SiC films was about five orders of magnitude higher that that of undoped films. Optical gap derived from the Tauc plot was 1.19 eV for Al-doped unhydrogenated film and 1.55 eV for hydrogenated film.

Constructing a building requires a legal building permit. A building process which is being done near or inside a Cultural properties protection zone is also controlled by The Cultural Properties Protection Law. The Cultural Properties Protection Law designates the Cultural Properties Protection zone, and it is separately authorized from a use district named by the Act on Planning and Use of National Territory. In this case, the construction of a building must meet the requirements of the Building Act and the Act on Planning and Use of National Territory, as well as the conditions of the Cultural Properties Protection Law in omnibus. That is, the construction must not cause any inconvenience to the protection of a property. The Cultural Properties Protection Law also requires an obligatory discussion with the head of Cultural Heritage Administration, as it establishes a restricted area. Furthermore, the law prevents constructing buildings at the place in which we find a Cultural heritage before or during the building process. This research is to study the relation of the building permits and the protection of cultural heritage by the Cultural Properties Protection Law on the whole.
