Among various life-time sports, the boxing-aerobic as aerobic exercise which unites the boxing with the aerobic has been recently attracted public attention due to usefulness and effectiveness. Naturally, the boxing-aerobic enables all over the body to equally train and each body part light and flexible as well as participants to be on a effective diet. The purpose of this study is to look into minutely life satisfaction according to health promoting life styles of participants in boxing-aerobic among life-time sports as well as offers fundamental information for self-control and life quality improvement of boxing-aerobic participants. Specially, it aims to identify differences in health promoting life styles in accordance with demographic characteristics of participants in boxing-aerobic. In order to accomplish the purpose, a convenient sample of 130 boxing-aerobic participants was selected, and the questionnaire for life styles test used for this study was made out by Seo,Yeon-Ok(1994). The background variables of the study were demographic characteristics such as age, education, average income, marriage, career to participate, blood type and religion. Through the analysis of established hypothesis and collected data, it is concluded that the higher monthly average income, the higher health promoting life styles.

This study was intended to provide the suggestion for marketing plan to enhance the revisit to the golf course through the influencers on the intention to revisit by making the research model with influencers on the golf course visitors's intention to revisit such as satisfaction, loyalty and image as independent variables. For this purpose, it attempted to conduct frequency analysis and factor analysis of items and conduct the cronbach's α test to confirm whether the combination of attributes had internal consistency. The explanatory power of the overall items was presented through the cumulative explanatory power(Cumulative variance ratio) and the detailed analysis of the research hypotheses was conducted. As a result, the following findings were obtained. Correlation analysis was conducted to analyze the significant relationship between golf course visitors' satisfaction, loyalty and image and intention to revisit. Fourth, multiple regression analysis was conducted to identify the relationship between golf course visitors' satisfaction, loyalty and image and intention to revisit. Based on the study results, this study attempted to present the following suggestions. Therefore, it is necessary to provide the optimal facility, provide golf course visitors with the service quality they wasn't through market research and make an integrative preparation for diversified and differentiated programs, employee and operation management and pricing. And to consider the plan to enhance the intention to revisit by analyzing golf course visitors' satisfaction. image and loyalty regularly. Also, It is necessary to attempt the CRM that can make practical use of database(DB) of information on customers's trivial matters. And it is necessary to consider the effective positioning plan that adjust or emphasize the existing market through evaluation on and comparison with competitors.

The purpose of this study was to analyze the effects of energy drink intake before exercise on cortisol and serotonin of elite Taekwondo athletes as elite athletes have a lot of stresses due to burden for matches and weight loss. A total of 18 male Taekwondo athletes (9 athletes for non-intake group and 9 athletes for intake group) had 90-minutes training 6 times a week for 8 weeks. To analyze the difference between the 2 groups before and after the intake, two-way ANOVA with repeated measure was performed. When looking at the change of cortisol, the main effect of time (p<.001) and interaction between time and group (p<.05) were shown. A statistical significant difference was shown before and after the intake in the groups with and without energy drink intake (p<.05). In terms of the change of serotonin, no statistically significant difference was found, but the serotonin was increased after intake of energy drink in the group with energy drink intake. The intake of energy drink 60 minutes before exercise is thought to help decrease stresses generated in training as it improves secretion of serotonin and cortisol of elite athletes who have high intensity training. However, caffeine increase vital level to offset the decreased effect of cortisol generated by exercise effect.

The purpose of this study is to investigate the effect of 10-week Nordic walking on blood lipids, growth hormone, and IGF-1 of obese adolescents. The subjects of the study were a total of 21 male obese adolescents whose body fat percentage is 30% or more, including exercise group (9 subjects) and control group (12 subjects). With the collected data, the mean and standard deviation for variables related to blood lipids and growth hormone were calculated. To test the difference between groups, two-way ANOVA was conducted by repeated measurement. When analyzing the result of the study, triglyceride and low-density lipoprotein cholesterol did not show significant differences between groups and times, but showed significant differences in the interaction between time and group (p<.05). The growth hormone did not show significant difference between groups and times, but showed a significant difference in the interaction between time and group (p<.05). In terms of IGF-1, s tatistically s ignificant differences was found between groups and times (p<.01), and a statistically significant difference was also found in the interaction between time and group (p<.05). Therefore, it was found that Nordic walking had positive effects on blood lipids, growth hormone, and IGF-1 of obese adolescents. Nordic walking should be highly recommended for resolving obesity of men and women of all ages in the future.

금속원자 반응기를 사용하여 몰리브덴 금속증기와 1,3-butadiene 유도체를 반응시켜서 (${\eta}^4$-CH$_2$CRCR'CH$_2$)$_3$Mo(R, R'= H 또는 CH$_3$)를 합성하였으며, 이 때 생성된 유기금속화합물에 대한 1,3-butadiene 유도체의 메틸치환기 효과에 대하여 논의하였다. 그리고 몰리브덴 금속증기와 다른 몇 가지 알카디엔화합물을 반응시켜서 유기금속화합물이 형성됨을 확인하였으며 이들은 공기 중의 실온에서 쉽게 분해 되었다. 또한 (${\eta}^4$-CH$_2$CCH$_3$CCH$_3$CH$_2$)$_3$Mo와 일산화탄소를 반응시켜서 (C$_6$H$_{10}$)$_2$(CO)$_3$Mo를 합성하였으며 이 화합물의 금속-리간드 결합에 관하여 논하였다. Various tris (${\eta}^4$-diene) molybdenums were easily synthesized by the reaction of various 1,3-dienes and molybdenum metal vapors by using metal atom reactor. The methyl substituent effect of the tris (${\eta}^4$-diene) molybdenum produced were discussed. And some alkadiene-molybdenum complexes which were easily decomposed in the air at room temperature were also formed.(C$_6$H$_{10}$)$_2$(CO)$_3$Mo were synthesized and its molybdenum-diene bond type were discussed.

원자력 해체시설 특성관리 시스템을 위한 CBD 프로세스의 적용 방안

조운형,박승국,최윤동,문제권,Cho, Woonhyoung,Park, Seungkook,Choi, Yundong,Moon, Jeikwon 한국정보과학회 소프트웨어공학 소사이어티 2012 소프트웨어공학회지 Vol.25 No.1

원자력 시설 해체 사업은 해체 시 방사성 물질이 발생하기 때문에 시설 해체에 있어서 일반적인 해체 공법을 사용하기 어렵다. 그렇기 때문에 원자력 시설의 해체 계획을 수립하는데 해체 대상시설의 성격을 조사하고 파악하는 것이 매우 중요하며 해체 대상 원자력 시설의 특성 자료 조사는 해체 폐기물의 양을 예측하고 해체 사업의 비용 산정에 크게 활용이 된다. 한국원자력연구원에서는 이를 목적으로 해체사업 대상 시설의 특성자료를 관리하는 시스템 DEFACS(Decommissioning Facility Characterization DB System)을 개발하였다. 그러나 원자력 시설 해체에는 시간이 오래 걸리기 때문에 부득이하게 해체 사업 중에 시스템을 개발하였고 이는 지속적인 요구사항의 변경이 발생하는 원인이 되었다. 이러한 이유로 개발에 있어서 일반적인 개발 프로세스를 적용키 어려웠던 바, 본 논문에서는 개발 중 요구사항 변경에 대한 효율적인 대응을 하기 위하여 기존의 CBD(Compoenent Based Development) 프로세스를 CD(Component Development)와 CBSD(Component Based Software Development)로 구분하여 변경사항에 대한 핸들링을 하나의 컴포넌트로 다루고 컴포넌트 별로 CBD를 재적용하여 재귀적으로 프로세스를 핸들링한다. 이로써 컴포넌트 변경에 대한 전체 시스템의 변경점을 최소화하고 컴포넌트와 프로세스의 독립성을 강화함으로써 요구사항 변경으로 인한 프로세스의 중지를 최소화 하였다. Characteristic of decommissioning target facility investigate and understand is very important. because radioactive materials occurs in the decommissioning and dismantling, so it is difficult to use a general dismantling method. Decommissioning nuclear facilities, the characteristics of the target of research to predict the amount of decommissioning waste, decommission projects costing is largely utilized. For this purpose, we developed DEFACS(Decommissioning Facility Characterization DB System) that manage characteristic of decommissioning target facility. But nuclear facility decommissioning takes long time. so we inevitably developed system during decommissioning works, it occurs many system changes. For this reason, it is difficult to apply general development process, so we take CBD process that divide CD(Component Development) and CBSD(Component Based Software Development) for handling change of requirement. it make Component of the overall system for changes to minimize changes by strengthening the independence of components and processes due to changes in requirements were to minimize stopping of the process.
