The purpose of this study was to examine the effects of the command teaching mehtod and problem solving teaching method by Mosston in achieving the serve, pass and volley skills of volleyball. The subjects of this study were 100 middle school boys and girls students divided into 4 classes. Two classes were taught volleyball skills by using the command teaching method and the others were taught by using the problem solving teaching method. All groups took experimental treatment 3 hours a week for 6 weeks. The subjects were pre-tested before they got experimental treatment. After 6 weeks of teaching the test of serve pass and volley skills applied AAHPERD(1969) were taken to the subjects. The experimentation of this study was based on based on 2(teaching method) X 2(sex) X 2(enforcement). The data analysis was practised by index of trinity dispersion. On the basis of the results compared and analyzed by the pre and post-test, the conclusions were drawn as follows. 1. In achieving the serve skills. there were significant differences between boy-groups and girl-groups but less differences between problem solving teaching method and command teaching method 2. In achieving the pass skills. problem solving teaching method was more effective, especially in boy-groups than command teaching method. 3. But. in achieving the volley skills. it showed no siginificant differences between boys and girls groups, problem solving and command teaching method

분광학적 방법에 의한 이소니트로소벤조일아세톤의 코발트(Ⅲ) 및 팔라듐(Ⅱ) 착물의 구조
吳岱燮,李萬浩,金修漢 慶北大學校 1979 論文集 Vol.27 No.-
Isonitrosobenzoylacetone is particularly interesting, as the isonitroso group has two potentially coordinating sites which can compete with the carbonyl groups in forming bonds with the metal ions. In this paper tris(isonitrosobenzoylacetonato)cobalt(III) and bis(isonitrosobenzoylacetonato) palladium(II) have been prepared, and their structures have been investigated. Spectroscopic studies lead to the conclusion that the both complexes do not contain an OH group in the chelated five-membered ring structure in which the ligand coordinates to metal through oxygen of the acetyl group and nitrogen of the isonitroso group. The coordination manner of this ligand is similar to that of isonitrosoacetylacetone obtained by Haldar et al.^(3)(4) Very weak intramolecular hydrogen bonding of the free ligand is indicated by nmr and ir spectra.

오만원,이철호 濟州大學敎 體育科學硏究所 1996 체육과학연구 Vol.2 No.-
The effect of TKD practice upon the sentiment and social manner of elementary school children was researched and the formation period of it was analyzed. To prove that the effect of TKD pratice has educationally much effective of forming the whole man it was made an object of this study that they are made up of 836 children and their 90 parents of elementary school. 4.5.6th grade among apprentices in drill halls of cheju-do was investigated and analyzed. So the following results were conculded. 1. The children and their parents think that in the change of sentiment through TKD practice. TKD practice of one year or more has more effective of improving the general standard of sentimemts of patience.brighness. self - confidence. reduction of a feeling of uneasiness, spiritual strength , control ability of feelings. concentration, etc. than that of three months below or to twelve months. 2. On the change of sociality by TKD practice all the students and their parents think that TKD practice of one year or more has more effective of improving the general standard of sociality of cooperation. sense of responsibility equality. independeuce. faithfulness, friendship, etc than that of three months below or four to twelve months. 3. On the change of manner of living by TKD practice their parents think that TKD practice of one year or more has more effective of elevating manner of living than that of three months below or four to twelve months. 4. Most of their parents agreed that they made their children practice TKD to have great confidence in themselves. By forming the above we can conclude following. For the high development of the change of sentiment, sociality, manner of living through TKD practice it is needed for children to train for more than one year. As most of the elementary school children have grown in the stream of overprotection, not feeling difficulty. they need the course of study for self - denial. including patience, staying power. Their parents make their children practice TKD to elevate spirit and have great confidence in themselves. So the apprentices from elementary school must realize that they can change their mind and behavior as better persons, developing their mind and body together only after they don't give up practicing TKD halfway but should practice TKD for more than one year with patience. And the readers of TKD should develop scientific and logical TKD practice programs, having the sense of mission that they charge themselves with part of education for the whole man in the course of school education.

중세 한국의 Sticksports에 대한 새로운 이해 I : 궁중 Sports로서의 Golfsports에 대하여
배영호,오만원,정구철 濟州大學敎 體育科學硏究所 1995 체육과학연구 Vol.1 No.-
To attempt new understanding of the traditional sports played from ancester, present study was focused on the entity of TAGU sticksports played by korean king's palace in the medieval times. Sticksports called Kyukgu, Tagu or Bonghee in the korean king's palace, as it's characteristic and traits, were very similar with present golf sports. And these sticksportdgolfsportts) were very prevalanced in the Korean Royal family from the beginning of the medieval times in this investigation results. Sticksports like Polo, these sports are seem to be introduced into the Korean Royal family from China in 12-13 century. As a results of investigation on the origin of golfsports controversy, the origin place of golfsports is not England or European country, but Asian country. The reasons are as follows ; 1) The origin times of golfsports was known generally from the beginning of the 13 century, but golfsports called Chui-Wan or Tagu(Bonghee) were played already in 11 century in East Asian countries. 2) In contrast of golfsports characteristics to "Soule a la Crosse" of Europe with "Chui-Wan" or "Tagu(Bonghee)" of East Asia, Chui-Wan or Tagu is advanced in 'Spielgedanke' and sports style of present golf than those of Soule a la Crosse of Europe. 3) Crosse, Golf, kolf, Golfen and kolben mean only stick, but Chui-Wan, Tagu(Bonghee) mean not only stick but also striking the ball by stick.

This study was carried out to determine the attachment parts and rates on the host fish and the successive stages of the glochidial encystment. A scanning electron microscope observation of the glochidia, the larvae of freshwater brivalve, Anodonta arcaeformis flavotincta, on the host fish, Carassius auratus, was conducted. The attachment rates on the host fish were 30.1%, 22.3% on the pectoral, the caudal, and the pelvic and anal fin, respectively. Glochidia, once attached to the host, have become encysted within 27 hours. The glochidia in fish tissues have sloughed between 13 days and 15 days when the water temperature was 16℃ in laboratory. During encystment, the epithelial cells of the host fish migrated actively toward the attached glochidia and covered them. In the encystment process, the encysted tissues in the host have become loose in seven days and exposured a pat of the glochidium in eight days after infection. No changes of the glochidial size have found before attachment and after sloughing.

홍경천의 천연 보존료로서의이용성을 검토하기 위하여 각종 용매로 홍경천 추출물을 제조하고 극성에 따라 순차분획, silica-gel chromatography, thin-layer chromatography, high perfomance liquid chromatography의 분리과정을 거쳐 순수 분리된 각 물질을 GC/MS(EI) spectrum, ¹H-NMR spectrum, ¹³C-NMR spectrum을 이용하여 항균물질을 동정하여 다음과 같은 결과를 얻었다. 홍경천에 대해 acetone, ethyl acetate, ethanol, methanol, chloroform, water의 각 용매로 추출한 결과 항균성분의 추출 용매로는 methanol이 가장 우수하였다. 홍경천 methanol 추출물을 n-hexane, chloroform, ethyl ether, ethyl acetate, n-butyl alcohol로 분획한 결과 ethyl acetate와 n-butyl alcohol 분획에서 우수한 항균력을 나타내었다. 홍경천 methanol 추출물은 그람양성 4균주와 그람음성 4균주에 대해 고체 배지의 경우 대체로 500 μg/mL에서 최소저해를 나타냈으며, 액체배지의 경우 100 μg/mL 내외에서 최소저해를 나타내었다.] Silica gel column chromatography에서 용매의 배율을 높여가며 용출한 결과 chloroform : methanol(8:2, v/v)의 비율에서 항균력이 가장 높게 나타났다. 분리된 항균성분을 silica-gel TLC plate에 용매의 비율을 높여가며 전개시켜 chloroform : methanol(9:1, v/v)에서 9개의 물질군을 얻을 수 있었으며, 그 중 항균력이 확인된 3개의 물질군을 HPLC와 NMR spectrum을 분석한 결과 gallic acid, (-)-epicatechin 및 kaempferol로 동정되었다. gallic acid, (-)-epicatechin 및 kaempferol의 항균물질 각각의 최소저해농도는 Staphylococcus aureus와 Listeria monocytogenes에 대해 gallic acid와 kaempferol 이 500 μg/mL, (-)-epicatechin이 100 μg/mL에서 저해를 나타내었다. The antimicrobial substances from Rhodiola sachalinensis were extracted, isolated and identified. The highest level of antimicrobial activity and its yield were obtained in methanol extract. The minimum inhibition concentrations of the methanol extract were 500 μg/mL on agar plate and 100 μg/mL in broth media for four gram positive and four gram negative microbials. The methanol extract was fractionated by n-hexane, chloroform, ethyl ether, ethyl acetate, and butanol, orderly. The separate was developed on the TLC plate with different solvent system ratio of chloroform and methanol. Nine substances were isolated from chloroform and methanol mixture(9:1, v/v). Among them, three isolates showed antimicrobial activity. Three substances separated by HPLC were identified by GC/MS(EI) spectrum and ^(1)H, ^(13)C-NMR spcetrum. They were gallic acid, (-)-epicatechin and kaempferol. The antimicrobial activites of each substances were shown gallic acid, (-)-epicatechin, kaempferol, orderly.
