This study examined and analyzed the intake pattern, purpose and motivation of nutritional supplements(vitamin, mineral, omega3, amino acid, ginseng and oriental medicine) of elite golf players according to their group, education level and career to provide players, parents and instructors with essential preventive resources of side effects by overdose without prior knowledge. Total 174 golf players including 43 professionals and 131 amateur players were specifically analyzed to achieve the goal of the study. Revised questionnaire, based on Chad et al.(1999), Sundgot-Borgen(2003) and Cheon Yoon Seok (2008) initially intended for national players in each country, was used to figure out the status of intake patterns of nutritional supplements of golf players. With SPSS 18.0 program, the collected resources had a cross analysis to examine intake status, purpose and motivation, and multiple response analysis was performed to find out the type of multiple intake by types of supplements. The results are as follows. First, professional players, high school players, long careered players and female players had taken nutritional supplements more frequency than amateur players, college players, short careered players and male players. Second, regarding intakes types of elite golf players by groups, amateur players preferred vitamin, oriental medicine, omega3, mineral and ginseng while professionals preferred vitamin, omega3, oriental medicine, ginseng, amino acid and mineral from a highest to lowest order. Regarding intake types by educational levels, high school players preferred vitamin, oriental medicine, omega and mineral while college students and adults preferred vitamin, omega3, oriental medicine, mineral and amino acid. Regarding intake types by career, players with less than 3 years career preferred vitamin, oriental medicine, omega3, mineral and amino acid, while players with more than 3 years career preferred vitamin, omega3, oriental medicine, ginseng, mineral and amino acid. Regarding intake type by sex, male players preferred vitamin, oriental medicine, omega3, ginseng, mineral and amino acid, while female players preferred vitamin, oriental medicine, omega3, mineral, ginseng and amino acid. Third, the purpose of intake by groups, education level, career and sex was mainly to recover from fatigue rather than to improve muscle strength. Fourth, regarding motivation and recommendation of taking nutritional supplements by groups, professionals took them by the recommendation of parents, themselves, coaches, friends and others, while amateur took them by the recommendation of parents, themselves, coaches and friends). By educational level, high school players took them by the recommendation of parents, themselves, coaches and friends, while college and adult players took them by the recommendation of parents, themselves, coaches, friends and others). By career, players with less than 3 years career took them by the recommendation of parents, themselves, coaches and friends, while players with more than 3 years career took them by the recommendation of parents, themselves, coaches, friends and others). By sex, male players took them by the recommendation of parents, themselves, coaches, friends, and others, while female players took them by the recommendation of parents, themselves, coaches, and friends). The result shows that elite golf players used to take nutritional supplements most frequently by the recommendation of parents.

본 연구에서는 감마선으로 유도된 돌연변이체들에서 공통으로 발현되는 방사선 관련 유전자들의 발현을 연구하기 위하여, B. lentimorbus WJ5의 방사선 유도 돌연변이체에서 발현되는 유전자를 DNA microarray로 동시에 탐색하였다. DNA microarray는 B. lentimorbus WJ5 genome을 무작위로 절단하여 2,000단편으로 구성하였으며, 감마선 (^(60)Co)으로 유도된 7돌연변이체의 발현을 정량적으로 관찰하였다. 클러스터 분석결과 발현된 408 유전자 중 27개가 감마선 유도 돌연변이체 모두에서 유의하게 발현이 증가되었다. 특히, 복구(mutL, mutM)에너지 대사 (acsA, sdhB, p하, yhjB, citB), protease(npr), 산화자극에 대한 환원 (HMM)관련 유전자들이 동시에 증가되었다. 이는 감마선 유도 돌연변이체들에서 자발적인 직/간접 복구 관련 유전자의 발현 증가는 방사선 노출 직후 보이는 stress response와는 다른 현상임을 나타내는 것으로 생각된다. To study the radiation related gene expression in mutants of Bacillus lentimorbus WJ5 induced by gamm radiation, the simultaneous gene expression was analyzed by DNA microarray. We constructed DNA chips including two thousand randomly digested genome spots of B. lentimorbus WJ5 and compared its quantitative aspect with seven mutants induced by gamma radiation (^(60)Co). From the cluster analysis of gene expression pattern, totally 408 genes were expressed and 27 genes were significantly upregulated by the gamma radiation in all mutants. Especially, genes involved in repair (mutL, mutM), energy metabolism (acsA, sdhB, pgk, yhjB, citB), protease (npr), and reduction response to oxidative stress (HMM) were simultaneously upregulated. It seems that the induction of the direct and/or indirect repair related genes in mutants induced by gamma radiation could be remarkably different from the adaptive responses against acute exposure to radiation.

This research was done to study and analyze the effects of job satisfaction and organizational commitment of judo directors. Also, to see what kind of characteristics show according to demographic properties. Furthermore, develop a academic basis for enhancing the quality of welfare, improving the effectiveness of teaching and strengthening organizational potency of judo instructors. In order to meet the purpose of this study, 192 subjects were analyzed. These subjects were chosen from private gyms, school judo teams and corporate judo teams having a minimum of 3 years experience in judo coaching.『Minnesota Satisfaction Questionnaire: MSQ』co-developed by Weiss, Dawis, England & Lofguist(1967) and 'three-component model of organizational commitment(emotional commitment, preserved commitment, normative commitment)' made by Meyer & Allen(1997) were customized to use as a tools to gather data. The retrieved data was computed by a statistical program called SPSS window 12.0 and was statistically analyzed by the purpose of the research. A one-way ANOVA was performed to verify the differences in job satisfaction and organizational commitment with age, education, pay among judo directors. Also, to compare the differences, Scheffe's method was used. Multiple recurrence analysis has been used to figure judo instructors' job satisfaction and causal relationship of organizational commitment. From the obtained research results a conclusion has been made based upon a few significant theoretical factors. First, noticeable difference in internal content was shown statistically, regarding the age of the judo director compared to the duty satisfaction. Second, appreciable variance in both factors, internal and external content, was shown statistically between judo directors experience in coaching and their job satisfaction. Third, noticeable variance was statistically spotted in the comparison between emotional commitment and experience of judo instructors. Forth, a statistical difference was noticeable in the pay of judo directors matching with internal content in job satisfaction.

토양과 지하수에서 pendimethalin의 지속성은 환경에 해로운 영향을 미친다. 경남 마산에서 분리한 pendimethalin분해 균주는 API CHB50 kit 시험, FAME 분석, 그리고 165 rDNA 염기서열분석 결과로 Bacillus sp. MS202로 잠정적으로 동정하였다. TLC, GC, 그리고 GC-MS 분석에 의해 Bacillus sp. MS202가 pendimethalin의 -NO₂를 -NH₂로 환원시킨다는 것을 알 수 있었다. 이는 일반적으로 알려진 호기성 미생물에 의한 pendimethalin 분해가 탈알킬화가 우선한다는 보고와 상반되는 새로운 결과이다. The persistence of pendimethalin in soil and ground water has an injurious effect on ecosystem. Pendimethalin-degrading bacterium was isolated from Masan, Gyeongnam province and temporarily identified as Bacillus sp. MS202 by the analysis of API CHB50, kit, FAME, and 16S rDNA sequence. From the analysis of pendimethalin metabolite using TLC, GC, and GC-MS, we found that the degradation of pendimethalin by Bacillus sp. MS202 did not result in the dealkylated form, but the formation of the reduced compound, 6-amino-2-nitro-N(1-ethylpropyl)-3,4-xylidine or 2-amino-6-nitro-N(1-ethylpropyl)-3,4-xylidine.

Generally alloplastic matrials such as collagen compound and liquid silicone injection. or autologous fat injection have been used for correction of surface irregularity. But, except for autologous fat injection, the other methods have been proved to be not effective or even dangerous. Then with the explosion in the popularity of liposuction, the autologous fat injection has been applied to variable clinical uses for contouring of the soft tissue irregularities. The author performed main operations with fat injection as ancillary procedure in 16 patients from 1993 to 1996, and long term follow-ups were reported. The lesions treated most frequently were cheeks, and others were thighs, legs, nasolabial folds and upper eyelids in order of frequency. The donor sites were lower abdomen, thigh, buttock and cheek. Our method of fat injection was used as an ancillary procedure for improving post-operative results in variable cases (craniofacial microsomia, fibrous dysplasia, asymmetry of leg, etc). And the important technical points in our method for reducing the absorption of fat after injection were atraumatic liposuction, multilayered dispersed injection, and 20% overcorrection. We obtained satisfactory aethetic results without major complications.

The purpose of this study is to examine the effects of the application of experimental practices, descriptive tests, and research papers among the performance assessments on the students' accomplishment, their scientific research abilities and their attitudes to science in high schools. Two classes among the first grade ones were selected and assigned to the control group and the experimental group respectively. T-analysis of pre-test showed that the two groups have the same quality(p>.05). The questionnaire made by the Korean Educational Development Institute(KEDI) was used. Its reliability is .689. The experimental process was evaluated on the basis of the criterion table and reports. T-tes and ANOVA were enforced with the SPSS/WIN(ver10.0) for the purpose of analyzing the mean difference between the two groups. The results of this study are as follows. First, though the application of the performance assessments showed that there were little significant differences between the scientific research abilities of the experimental group with the experimental practice and those of the control group(p>.05), and the results of the pre-test and the post-test on the experimental group revealed that there were significant effects on improving the students' scientific research abilities(p<.05). Second, the result of the test using ANOVA at each research course factor showed that there was no significant difference at most research course factors that there were significant differences between the two groups in expanding the scientific research abilities of classification and measurement(p<.05). Finally, the results of the pre-test and the post-test by application of the performance assessments showed that they had significant effects on changing the students' attitude to science subject positively(p<.05). In addition, the results of the pre-testing and the post-testing on the sub-factors of the attitude related to science showed that there were significant changes in the concept of 'self-consciousness' and the attitude to learning(p<.05). In conclusion, the application of the performance assessments has positive effects on improving the high school students' scholastic achievement, scientific research abilities, and attitudes to related to science. Consequently, science teachers should be willing to use various performance assessments in the class.
