DBPs and T&O(taste-and-odor) compounds in drinking water is one of main source to deteriorate water quality. So, these compounds can cause adverse health effects and result in many consumer complaints aesthetically. This experiments carried out to investigate the effect of boiling water on DBPs and T&O compounds in the tap water. THMs and TCM concentration were reduced by 91.3%, 88.9% after 5 min of boiling, respectively. It is certainly, resulted from volatilization of TCM. TCAA concentration decreased when the water was boiled, too. By contrast, the concentration of DCAA was increased with duration time from boiling-point. The reduction of TCAA from the boiled water can be attributed to chemical transformation like decarboxylation. T&O compounds such as geosmin and 2-MIB was effectively removed by boiling of water, resulting in the removal efficiency of 97.1%, 94.4% after 5 min of boiling, respectively.

This study was carried out to investigate the physicochemical characteristics with the elapsed time of $1\~10$ minutes after adding green tea leaves in the tap water. The results are summarized as follows: 1. $UV_{254}$ measurement increased sharply in direct opposition to increasing conductivity slowly. It is expected that the water soluble organic matters were better extracted than minerals. 2. Residual chlorine decay coefficients evaluated by assuming first-order reaction was increased in proportion to adding weights of green tea leaves. 3. In DBP formation experiments, residual chlorine decreased when reaction time was elapsed. whereas DBPs such as HAAs and THMs increased with the passing of time. From these results, it was showed that residual chlorine decay was related with the formation of DBPs. Therefore, use of boiled tap water in preparation of green tea is suggested if the residual chlorine in the tap water is high.

The purpose of this research is to discover correlation of the relationship of university Taekwondo coaches and athletes with athletes’ satisfaction and commitment on the team. The subject of this study is 422 Taekwondo players participated in University Taekwondo Championship in April and May of 2012, hosted by Korea University Taekwondo Federation. Data has been analyzed with SPSS program(17.0 version). Such analyses include exploratory factor analysis, frequency analysis, Pearson’s correlation analysis, and multiple regression analysis. As a result, first, the relationship between university Taekwondo coaches and athletes had meaningful correlation on the commitment to the team, especially on affective commitment among other elements of the team element. Second, the relationship between university Taekwondo coaches and athletes also had meaningful effect on athletes’ satisfaction. It showed that the human relationship was more influential on exercise satisfaction and negative satisfaction than on life satisfaction. Third, the attention and commitment that university Taekwondo coaches paid had meaningful effect on athletes’ satisfaction. It showed that such commitment presented more correlation to life satisfaction part. Good relationship with university Taekwondo coaches allow players to be more committed to the team, which gives greater satisfaction to athletes and brings the improvement of their performance. Thus, Taekwondo instructors in the university team should not put their effort only on the way to improve players’ Taekwondo skills. They should also endeavor to build up emotional relationship that respects and sympathize athletes.

Cytogenetic and hematological analysis was performed in peripheral blood obtained from pigs bred in the high background radiation areas (HBRA) (Cheongwon-gun and Boeun-gun) and a control area. The frequencies of gamma-ray induced micronuclei (MN) in the cytokinesis-blocked (CB) lymphocytes at several doses were measured in three pigs. An estimated dose of radiation was calculated by a best fitting linear-quadratic model based on the radiation-induced MN formation from the swine lymphocytes exposed in vitro to radiation over the range from 0 mGy to 1,969 mGy. The measurements performed after irradiation showed dose-related increases in the MN frequency in each donors. The results were analyzed using a linear-quadratic model with a line of best fit of $y=0.0005404D^2+0.04237D+0.00833$ [y = number of MN/cytokinesis-blocked (CB) cells and D = irradiation dose in Gy]. MN rates per 1,000 CB lymphocytes of pig from the HBRA (Cheongwon-gun, Boeun-gun) and the control area were $6.70{\pm}2.36$, $9.00{\pm}3.50$ and $11.00{\pm}2.98$, respectively. The MN frequencies of CB lymphocytes from pigs bred in three areas means that the values are within the background variation in this experiment. The MN frequencies and hematological values were similar regardless of whether the pigs were bred in the HBRA or the control area.

비앙키 우주론에 대한 Wheeler-DeWitt 방정식의 디랙 평방근을 구하였다. 제 1 형과 제 9 형의 비앙키 시공간에 대하여, ``시간`` t의 역할을 하는 변수 α의 l계 미분으로 구성되는 파동방정식이 얻어졌다. 이 방정식은 양의 값을 가지는 확률밀도와 이에 따르는 보존류를 준다. The Dirac-Square-Root formulation of the Wheeler-DeWitt equation for the Bianchi Universe is presented. The wave equations which are linear in time-like variable α are obtained for the Bianchi type-I and IX spacetime using purely geometrical coordinates. These equations give the conserved current with positive-definite probability density.

김창모(Changmo Kim),하인숙(Insuk Ha),이상복(angBock Lee) 한국방사선학회 2013 한국방사선학회 논문지 Vol.7 No.3
우리나라는 태권도의 종주국임에도 불구하고 신체활동량과 그에 따른 에너지 소모량에 대한 기초연구가 미흡하며 이에 대한 연구가 시급한 상태이다. 본 연구에서는 센서(SenseWear?? PRO₂ Armband)를 이용하여 태권도의 신체활동량을 획득하였고, Inbody 520을 통하여 체성분 데이터를 획득 하였으며, CT로 하체부위(허벅지)를 스캔하여 허벅지 근육면적 데이터를 추출하였다. 획득된 데이터를 이용하여 허벅지 둘레와 근육면적의 상관관계, 허벅지 근육면적과 분당 에너지 소모량의 상관관계를 분석하였다. 분석결과 실험자 8명의 평균 허벅지 근육면적은 132.79cm²였으며, 무릎뼈(Pattela) 위 20cm의 평균 허벅지 전체 면적은 178.79 cm²이었다. 실험자들의 허벅지 둘레와 근육면적은 상관관계가 있는 것으로 나타났다. 실험자들의 평균 분당 에너지 소모량은 6.94 칼로리였으며, 허벅지 근육면적과 평균 분당 에너지 소모량도 상관관계가 있는 것으로 나타났다. Despite the suzerain of Korea Taekwondo physical activity and a corresponding lack of basic research on energy consumption and the status of this research is urgent. In this study, the sensor (SenseWear?? PRO2 Armband), using physical activity were obtained in Taekwondo, and body composition data were obtained by Inbody 520, We were thigh scan using CT scanner and thigh muscle area by CT scan data were acquired. Result of analysis, average thigh muscle area of experimenter 8 people was 132.79 cm², Of 20 cm above the patella thigh was a 178.79 cm². Thigh circumference and muscle area showed that the correlation. The average energy consumption per minute was 6.94 calories, and thigh muscle area and average energy consumption per minute also showed that correlation.
