The purpose of this study is to determine how a Taekwondo player's athletic satisfaction affects his/her psychological health and overall personal happiness. A questionnaire survey was carried out on a sample group of 200 students attending colleges located in Seoul and Gyeonggi Province. Then, 23 questionaries deemed not trustworthy were eliminated, leaving 178 questionaries for analysis. The questionnaire, which contained total 128 questions, showed the confidence level falling between .5241 and .8945 (Cronbach's alpha). The study, which relied on frequency analysis, t-test, One-way ANOVA, and Scheffe test, produced the following results. First, athletic satisfaction showed a statistically significant difference (5% range) depending on sex, school year or athletic experience. Second, psychological health resulted in a statistically significant difference (5% range) depending on sex or athletic experience while no difference was noticed regarding school year. Third, happiness in life showed a statistically significant difference (5% range) depending on sex or school year while no difference was noticed with regard to athletic experience.

Common buckwheat has the sporophytic self-incompatibility mechanism and that’s why it has the ability to cross pollinate between two plants with different styles (thepin type and thrum type). The S supergene is thought to govern self-incompatibility, flower morphology and pollen size in buckwheat. Already, we have produced self-compatible buckwheat lines by an interspecific hybridization between Fagopyrum esculentum and F. homotropicum by embryo culture. The pollen size of F1 plants produced by a cross between a pin type plant and the self-compatible plant was similar to that of the self-compatible lines and segregated together with flower morphology without exception. The pollen tubes of the self-compatible plants were compatible with styles of the pin plants but incompatible with the styles of thrum plants. But, the pollen tubes of thrum flowers were compatible with the styles of self-compatible plants. Also, the pollen tubes of pin flowers were incompatible with the styles of self-compatible plants. Already, from these results, we have reported a tentative genotype for heterostyle and homostyle flower types. Homomorphism was controlled by a single allele Sh, while the pin/thrum-complex gene was governed by a single genetic locus S, with two alleles, S and s, which control Ss (thrum-type) as well as the ss (pin-type), respectively. Corresponding represents the case of a single locus S with three alleles, Sh, S and s, and the phenotypes, homomorphic, pin and thrum. It can be characterized by relationship of dominance, S>Sh>s. Using the two self-fertile lines, one is considered as the long-homostyle flowers and the other is considered as the short homostyle flowers. If the short-homostyle trait had arisen by recombination in the S supergene, its genotype would be considered to be GIs ip a/GIs ip a. The pollen tubes of the short-homostylous plant should be compatible with the styles of thrum plants. Also, the pollen tubes of short-homostylous plants should be incompatible with the style of long-homostylous plants, and the reciprocal cross also should be incompatible, because the genotype of long homostyle is gis Ip PA/gis Ip PA. Furthermore, the flower morphology of F1plants produced by the cross between cross and short homostyle flowers should be thrum or short homostyle and only short-homostylous plants should be produced by the cross between pin and short homostyle flowers. However, the compatibility or incompatibility of short homostyle flower was not clarified. So, we need to clarify the compatibility or incompatibility of the style of short homostyle flowers for the next step.

목적 : 1992년 이후 국내에 유입, 확인되는 V. cholerae 균은 현격한 증가 추세를 보이고 있으며, 1995년도 국내 집단 발생 콜레라의 역학적 양상이 종래의 경우와 상이한 바 있어 최근의 콜레라균 유입상황과 국내 역학적 특성을 정리하여 향후의 방역 대책에 참고로 하기 위하여 본 연구를 시행하였다. 방법 : 국내 유입 V. cholerae 균은 세균학적 방법에 의해 1986-1995년 사이에 확인된 균주를 대상으로 분석하였고, 국내 집단발생 콜레라는 1995년도에 내국인 거주자에게서 진성 콜레라 환자로 구명된 환자를 대상으로 역학적 양상을 살펴보았다. 결과 : 국내 유입 V. cholerae균은 1992년 이후 1995년 사이에 계절과 무관하게 뚜렷한 증가 추세를 보였다. 1995년도 콜레라 국내 집단 발생의 역학적 양상은 초발 환자가 인지되면서 단기간 사이에 지역적 연고가 없는 다양한 지역에서 콜레라 환자 발생이 확인되었다. 환자 발생 지역 내에서는 비교적 소규모 환자 발생에 그쳤고 진성 콜레라 환자로 확인된 환자 중 사망자는 없었으며 남성에서 여성보다 발병율이 높았다. 결론 : V.cholerae O1균의 국내 유입이 최근 현격히 증가되었고, 1994년에는 V. cholerae O139균의 국내유입이 처음으로 확인되었다. 콜레라 환자의 국내 집단 발생 위험은 1992년 이후 증가되었으며 1995년도의 집단 환자 발생은 지역적 연고가 없는 다양한 지역에서 비교적 단기간에 사망자 없이 소규모의 환자 발생양상을 보였다. Background: Imported Vibrio cholerae strains have increasingly been found since 1992 and the pattern of recent cholera epidemic outbreak in Korea showed a little difference from that of former epidemic outbreak. Methods: We had collected suspected V. cholerae isolates from Quarantine Stations or Public Health Laboratories, which were identified as V. cholerae O1 or O139. Epide miological analysis was made on the base of field surveys. Results: During the period from 1986 through 1995, 138 V. cholerae strains were imported. Nearly 85.5% of the strains (118 strains) were imported within recent 4 years from 1992 to 1995. One hundred and twenty-eight strains were E1 Tor-Ogawa type V. cholerae O1, 6 strains were V. cholerae O139 and 4 strains were E1 Tor-Inaba type V. cholerae O1. Of 138 strains, 71 strains were isolated from the airplane toilet swab and 67 strains from the passengers who entered into Korea after international travel. From 1993 to 1995, 101 strains were imported from the Southeast Asian countries; including Thailand(65), Indonesia(17), Philippines(10), Hongkong(6) Singapore(2) and Vietnam(1). During the cholera epidemic in 1995, 68 patients with V. cholerae O1 (E1 Tor-Ogawa) were found. Oneset of the index-case occurred on August 26th and the last on September 13th. Geographically it occurred in Incheon city(25), Chungcheongnam do(25), Kangwon do(6), Kyungsangbuck do(5), Kyunggi do(4), Daejeon city(2) and Pusan city(1). Of total 68 cases, 39 were male. Cases were found in all age groups, but it was more common in elderly groups. During the epidemic, E1 Tor-Ogawa type V. cholerae O1 strains were also isolated from the coastal sea water of Kanghwa kun where the epidemic outbreak occurred. Conclusions: In Korea, the imported V. cholerae O1 and V. cholerae O139 strains have increasingly been found without seasonal variation since 1992. Cholera epidemic outbreak in 1995, occurred simultaneously at many different local areas within a short period without mortality.

Nowadays apartments in korea should be concerned about air change rate 0.7/h and installing sprinkler system according to a building equipment standard and the Fire Service Law at same time. To use this ceiling plenum ventilation system in a dwelling as part of a residential and commercial complex have to choose the pipe diameter of the air supplying outlet and branch duct as 150㎜ and CAV(constant air volume single duct system) or a mixed supply system. If the ceiling height is low or it is used in a public apartment supply duct next to the total heat exchanger and each room increases effective area of the air supplying outlet. Then the mixed supply system should be used.
