Soil respiration has been recognized as a key factor of the change of organic matter and fertility due to the carbon and nitrogen mineralization. In this study, we evaluated the effect of soil respiration on the light fraction-C and inorganic N content depending on temperature in soil applied with organic matter. Soil respiration was calculated by using total CO2 flux released from soil applied with 2 Mg ha-1 of rice straw compost and rye for 8 weeks incubation at 15, 25, 35°C under incubation test. After incubation test, light fraction and inorganic N content were investigated. Rye application dramatically increased soil respiration with increasing temperature. Q10 value of rye application was 1.69, which was higher 27% than that of rice straw compost application. Light-C and NO3-N contents were negatively correlated to soil respiration. Light-C in rye application more decreased than that in rice straw compost with temperature levels. These results indicate that temperature sensitivity of soil respiration could affect soil organic mater content and N availability in soil due to carbon availability. Also, light fraction would be useful indicator to evaluate decomposition rate of organic matter in soil under a short-term test.

Carcinoma of the urachus, which is a rare entity with poor prognosis, had proved difficult to diagnose radiographically. Since urachal carcinomas develop primarily in or outside the blader, with invasion of the mucous membrane occuring later, the tumor is likely evade dtection until it is too late. However, with the advent of computed tomography, the anatomical relationship of a mass to the bladder can be better demonstarted and the diagnosis suggested. The purpose of this presentation is to describe a case of the urachal carcinoma and to show the usefulness of CT in the diagnosis and follow up.

등속성 측정(isokinetic dynamometry)은 1960년대 후반부터 엘리트 선수의 근력과 파워를 측정하기 위하여 이용되기 시작하였으며 이 후 단일 근육군의 역동적인 근기능을 조사하기 위한 운동생리학적 연구의 표준도구로 정착되었다. 등속성 측정은 각속도, 위치, 동작 범위, 수축 방향, 움직임의 연속성 등에 대한 다양한 조건에서 수행될 수 있으며, 이를 통하여 다양한 측정 변인의 추출이 가능하다. 따라서 등속성 측정을 단일하고 일반적인 검사방법으로 여기는 것은 정확하지 않다. 특정 조건에서 등속성 측정방법의 타당도와 신뢰도가 입증되었다고 해서 모든 등속성 측정이 신뢰도가 높고 타당하다고 말할 수 없다. 같은 이유로 특별한 등속성 장비나 적용에 대한 제한적인 증거를 등속성 측정의 총체적인 유용성에 반하는 증거로 여겨서도 아니 될 것이다. 등속성 측정의 타당도와 신뢰도는 평가 상황에 따라 다양하게 고려될 수 있다. 본고에서는 근력 평가도구로서 등속성 측정의 주요 측면에 대하여 고찰한 Wrigley와 Strauss(2000)의 논의를 바탕으로 등속성 근력 측정의 목적과 이와 관련된 등속성 측정의 타당도와 신뢰도에 대하여 살펴보고자 한다.

Correct and accurate inference depends on an appropriate experimental design and a proper statistical model. Most of data in many sports science studies multilevel structures, but the structures have been ignored in data analysis. The purpose of this study was to introduce multilevel data analysis and to explore the possible applications to the study of physical education and sports science. The multilevel data analysis have two important principles. The first is that observational and experimental units should be distinguished and taken into consideration in analyzing multilevel data. This can eliminate the problems of the classical statistical model like ANOVA or regression analysis. And the second is to build to an analysis based on the data structure. The major advantages of the multilevel data analysis in analyzing multilevel data include improving the estimation of individual performance, modeling cross-level effects, and partitioning variance-covariance components(Bryk & Raudenbush, 1992). Furthermore, the multilevel data analysis can be used to assess the change, such as studying the structure of individual growth and estimating important statistical and psychometric properties of collections of growth trajectories, discovering correlates of initial states and change rates, and testing hypotheses about the effects of one or more experimental treatments on growth curves. Through reviewing prior studies in related to multilevel data analysis, improving inference in small samples, testing cross-level effects, partitioning variance-covariance components, meta-analytical study, and assessing the change of physical fitness or human performance have been proposed as the possible applications for physical education and sports science. In conclusion, for more valid inference in sports science study using the hierarchical data, multilevel data analysis and the possible applications should be considered.

Elementary physical educators frequently employ performance observation as their primary assessment strategy. The purpose of this study was to determine the minimal conditions of observation needed to obtain generalizable results across observers, trials, and subjects for the balancing on a balance beam, cartwheel on a mat, forward rolling on a vaulting horse, and circling on a bar. Ten sixth grade male students were rated on three trials by 3 observers. The results were as follows; 1) Two observers and five trials are needed for evaluating the balancing on a balance beam (.81). 2) One observer and two trials are required for the cartwheel on a mat (.82). 3) One observer and three trials are required for the forward rolling on a vaulting horse (.83). 4) One observer and two trials are required for the circling on a bar.

Sports Talent Identification and Selection in Korea
고병구 국민체육진흥공단 한국스포츠정책과학원 2014 International Journal of Applied Sports Sciences Vol.26 No.2
The purpose of this study is to review how Korea Institute of Sport Science (KISS) had carried out sports talent identification and selection for enhancing athletic performance over the last three decades. In the 1980s, KISS had to prepare for the 1986 Asian Games and the 1988 Olympic Games. So, KISS developed test items for sports talent identification for various sports and had identified 4,359 sports talents over 30 sport events. Moreover, KISS developed the standards for elite athlete and had selected talented athletes using them. In the 1990s after the two big sports events, KISS established Talented Athlete Selection Center and constructed the foundation of elite athlete recruitment system. In the 2000s, Korea had suffered a lot of difficulties in recruiting new athletes because of government’s birth control policy effect and economic affluence. So, KISS developed an innovative sports talent identification program and had searched about 500 talented children every year. And KISS developed a new talented athlete selection program and had selected 1,682 talented athletes during 2000s. These new sports talent identification and selection programs are flourishing until now and would be the best sources of national team members in the future.
