The objective of this study is to come up with the opportunity to give a profound thought to the traditional and authoritaive practice of corporal punishment in terms of the behavioual attiudes of instructors and players toward the punishment inflicted on players in the course of sports activites, psychological and sentimental change and problems with the viewpoint twoard the matter at hand. As a consequence, the following have been brought up. (1) The change of point of view twoard corporal punishment is in urgent need so as to strike the balance between player's right and instructor's authority. (2) The methods of corporal punishment in the context of sports training for the purpose of physical and mental fortification should be devised. (3) In case of inevitable punishment, see to it that the body parts that can undergo less impact such as hips are chosen, and that you make the player understand why you are obliged to take such acts lest the player should experience mental shock. (4) The instructions on a humanitarian basis need carrying out through the removal of traditional value or prejudice that corporal punishment proves to be of help to the improvement of players' sports skills. Besides, the effectiveness should be checked out. (5) The instructors who inflicted corporal punishment on players came up regretting about their behaviors. Given the remarks, instructors must come up with more flexible, positive and productive methods. For instance, the instructors ought to try love, encourage and support their players, putting their team into unity. Furthermore, instructors need to realize their generosity results in players'. In conclusion, the anachronistic, authoritative point of view of sports instructors toward corporal punishment is required to change given the current social trened to avoic violence and the demand for players' rights.

The purpose of this study is to clarify the self-evaluation method of physical education classes by students. Some efficient instruments for the synthetic evaluation have already been developed. However, the reliable instrument for the self-evaluation seems to be missing. Therefore, we intended to develop a convenient and effective instrument for self-evaluation of physical education class which can be used in each teaching unit. The subjects were 426 students from 4 senior high schools. Factor analysis, multiple regression, and oneway ANOVAis used to estimate relationship between each variables. These results were as follows ; 1) The self-evaluation factors exist three factors representing dimensions of self-evaluation ; motivation of learning, cooperation, and outcome of learning. 2) When the self-evaluation factor scores are compared for differences in each senior high schools, mean scores differ significantly for all. 3) When the self-evaluation factors are compared for the result of practical teaching, three factor scores showed significant and positive relationships with those of the comprehensive evaluation items concerning good or effective instruction. Thus, the factors were interpreted as effective standards for self-evaluation.

JMX기반 클러스터에서의 효율적 스케줄링

李基哲,蔡熙星 弘益大學校 科學技術硏究所 2004 科學技術硏究論文集 Vol.15 No.-

With new Java technologies like J2ME, J2EE, JMX, Jini and JDMK, the necessity of integrating existing Java-based system functionalities arose. Moreover, with the advances of the technologies related to application servers, the use of EJB technology based application servers increased rapidly. Recently, the demand of supporting on-line multimedia contents which have multiple terabytes size data increases. To address this problem, a clustering technology which interconnects multiple computers with moderate price range has been proposed as an alternative to a single, high performance high price server. In this paper, through experiments, the adaptive characteristic and load balancing effects are presented. Our scheduling scheme has been experimented and compared with conventional methods. The experiments show promising results, opening the possibility of using clustered Java-based systems for general purposes. Our system proves to adapt to various situations and balance its load effectively.
