In this paper, we studied on the effective structure of an e-Learning Korean Support System for foreigner based on computer systems which is to obey the rules of IMS/AICC International Standard regulations based on LCMS and SCORM. The most important task on this study is to support the function of self-study module through the review of the analysis and results of Korean learning and learning customs. We studied the effective PMS detail modules as well as the Standard Competency Module Management System, which related to LMS/LCMS, Learning an Individual Competency Management System, Competency Registry/Repository System, Knowledge Management System based on Community Competency Module, Education e-survey System and Module learning Support Service System. We suggested one of standard Effective Model of learning Korean Support System which is adopted in a various techniques for foreigner.

Beginning in the 2007-2008 season, the men's pro-basketball league changed a foreigner selection method by introducing a draft system which leads to a tryout from the free agency system. Also in the same season, the woman's pro-basketball league changed its system from one that permitted foreign players to one that doesn't allow foreign player participation. The reason for this change is thought to be financial problems. However this institutional change brings about the reduction in the quality of basketball and it will affect spectators in a negative way. The empirical study attempted to analyze the effects which follows an institutional change in Korean men's pro-basketball. The research showed that the men's pro-basketball league wasn't affected at all due to foreigner selection method by a draft system that led to a tryout from the free agency system.

This paper presents a scheme that generates a caption file by extracting a Closed Caption stream from DTV signal. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be supported by an enforcing law in all broadcasting services in 2008. In this paper, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file (SAMI and SRT) using the extracted caption data and time information. Experimental results verify the feasibility of a generated caption file using a PC-based media player which is widely used in multimedia service.

본 연구의 목적은 배구경기의 스파이크 동작에서 시간, 거리, 속도, 각도요인 등 제반 운동학적 변인들을 분석하여 스파이크의 과학적 훈련이나 지도에 유용한 정보를 제공하는데 있다. 대상자는 2008-2009 V-리그에 출전한 남자 용병선수 4명이다. 두 대의 고속비디오카메라를 사용했으며 3차원 동작분석 법으로 분석한 결과를 토대로 한 결론은 다음과 같다. 도약스텝의 소요시간은 .33초였으며, 안젤코 선수는 다른 선수들보다 발구름 시간을 조금 더 길게했다. 현재 공격력에서 더 상위에 있는 안젤코와 앤더슨은 전체 스파이크 동작구간의 거리를 4m 이내로 비교적 짧게 했다. 신체중심이 최저에 이른 순간은 도약스텝에서 지지하고 있는 오른발을 왼발이 통과하는 시점이었으며, 신체중심의 최대 높이는 2.30m로 임팩트 직전에 나타났다. 신체중심의 수평속도는 도약스텝의 초반부에 4.19m/s로 가장 높았으며, 도약 직전 앞발의 지지기에 최저치에 도달하는 것으로 나타났다. 신체중심의 수직속도는 도약구간에 오른발의 접지 후 최저치에 이르렀으며, 앞발의 이지 후 최대 속도에 이르는 것으로 나타났다. 타점은 3.22m, 볼속도는 최대 28.18m/s로 나타났다.
