The purpose of this study was to investigate the effect of Isotonic Training and Isotonic isometric complex Training to Knee joint Isokinetic muscle function in the high-school Taekwondo athlete. This subjects were randomly divided into two groups; a Isotonic Training group (n=7) Isotonic isometric complex Training group (n=7), Taekwondo athletes share each, 12 weeks between executes a motion. peak torque, H/Q ratio, bilateral muscular ratio muscular endurance of knee joint measured. For this study, two-way ANOVA with repeated measure were used. The result of this study presents between groups was not plain difference expressed. H/Q ratio, bilateral muscular ratio, muscular endurance was plain difference expressed after 12 weeks point of time (p>0.05) and peak torque was plain difference expressed (p<0.05). Conclusion each group did not appear all but one (peak torque), but point of view exercise was effect H/Q ratio, bilateral muscular ratio, muscular endurance, peak torque plain difference expressed.

With the fast development of complex science, lots of social networks are studied. We know that the social network is widely applied in analyzing issues in human culture, economics and web sciences. Recently we witness that some researchers began to compare the social network constructed from fiction literatures(literature social network) and the real social network obtained from practice. But we point that previous approaches for literature social network have some drawbacks since they completely depend on the biographical dictionary constructed for a designated literature. So since the previous approach focus on the few important characters and peoples around them, we can not understand the global structure of all characters appeared in the literature at least once. We propose one method to extract all characters appeared in the literature and how to make the social network from that information. Also we newly propose K-critical network by applying frequency of the named characters and the strength of relationship among all textual characters. Our experiment shows that the K-critical measure could be one crucial quantitative measure to compute the relationship strength among characters appeared in the object literature.

사용자 적응형 추천 시스템의 목적은 사용자의 선호도와 행동 정보 등을 분석, 분류하여 그를 바탕으로 각 사용자가 필요로 하거나 선호 할 만한 서비스를 사용자에게 추천하여 사용자 편리성을 높이는 것이다. 그러나 기존의 추천 시스템은 새로운 사용자의 등장이나 새로운 서비스의 등장 시 분석에 많은 시간을 필요로 하거나, 과특성화와 희귀성이라는 특성으로 인한 추천 서비스 단순화 등의 문제점을 안고 있다. 본 논문에서는 새로운 사용자 등장 시 결정 트리를 이용한 분류로 분석시간을 줄이고, 새로운 아이템의 등장 시 분석시간의 감소와 다양한 사용자 중심적인 추천을 위해 대리자를 이용한 사용자 군집화와 추천을 수행하는 새로운 모델을 제시한다. 또한 제안된 모델을 분석하여 위의 문제점들이 어떻게 해결되는지 설명한다.

Less has been written about the PCL than the ACL. There has, however, been an increasing amount of the interest in the PCL recently. Surgical reconstructions using grafts are often performed. However, these procesures often fail to provide long-term stability and function. Graft attachment sites are critical determinants of success in the PCL reconstruction. The clinical literature contains conflicting recommendations for graft attachment sites. We present a review of the isometry of the PCL.

The paper analyzes the effects of the emergence of Fintech on the banking and savings banking industries in Korea. From the analysis, we find that net interest margin decreases and credit supply increases with the advent of Fintech in the banking industry. Similarly, in the savings banking industry, a profitability index decreases. This is interpreted as the result of reduced monopoly power and increased efficiency in the industries, inducing an increase in overall consumer benefits. Individual financial institutions may, however, experience difficulties such as reduced profitability and increased Fintech investment costs.

1970년대 초 석유파동과 자원 민족주의의 대두와 더불어 지구상의 석유매장량의 한계성이 더욱 더 인식되었고, 석탄자원도 가용성이 오래 지속되지는 못할 것으로 알려져 에너지의 안전성이 세계각국의 중대한 과제로 등장할 때 제2차 석유위기가 도래하였다. 따라서 인류의 생존을 위한 에너지원은 태양에너지와 원자력 에너지로 귀착되었고, 또한 원자력에너지의 문제점과 한계상황으로 인해 태양에너지의 이용이야말로 무한량, 무공해라는 점에서 인류의 영원한 생존을 위한 에너지원으로 등장하였다. 범국민적인 에너지 소비절약운동을 전개하고 있는 우리나라에서도 앞으로 에너지 수요는 급격히 증가할 것이고, 에너지 절약은 우리가 숙명적으로 극복해야할 중요과제로 남아있어, 본지에서는 효과적인 에너지절약 방법의 하나로 등장한 태양열 에너지에 대해 몇회에 걸쳐 알아보도록 한다.

지난 2008년 12월말 정보보호 시스템에 대한 보안성 평가의 소요시간과 비용을 절감하기 위한 정책이 등장하면서 이에 대한 기사들이 등장했다. 보안성 평가과정에 있어 비용과 시간 절감은 정보보호 업계로서는 반가울 수밖에 없는 일. 그렇다면 실제 그 과정과 성과는 어떠했을까.

This paper explores the inter-ethnic conflicts between Blocks and Hispanics focusing on the emergent Hispanic ethnictity that reveals situational character in the US contexts. In the US census categories, major groups are indetified by race and ethnicity in which the Hispanic orgin is a category based on their common language while diverse in nationality. The census defined Hispanic category extends conveniently to acquiesce Affirmative Action and other government resource distribution. Internally, Hispanics have established numerous organizations to coalesce and assure their interests. The achieved dual language program and jurisdictional revision to represent language minority work as leverages to their cohesiveness. Under diminishing public resources and welfare payment, it is more difficult sharing burdens than benefits between minority groups. Block are not comfortable with the benefits Hispanics receive form the civil rights achievement without having had to struggle for it. The ethnic conflicts of the have-nots have become a new ethnic phenomenon attributable to the emergent Hispanic ethnicity.

In this paper, we propose and describe the system to visualize the story of contents such as movies and novels. Character-net is applied as story model in order to visualize story. However, it is the form to be accumulated for total movie story, though it can depict the relationship between characters. We have developed the system that analyzes and shows the variation of Character-net and characters' tendency in order to represent story variation depending on movie progression. This system is composed by two windows that can play and analyze sequential Character-nets by time, and can analyze time variant graph of characters' degree centrality. First window has a function that supports to find important story points like the scenes that main characters appear or meet firstly. Second window supports a function that track each character's tendency or a variation of his tendency through analyzing in-degree graph and out-degree. This paper describes the proposed system and discusses additional requirements.
