To understand the effect of midsole on the bending stiffness of footwear, bending moment is studied with various hardness and thickness of polyurethane(PU) and poly(ethyl one-co-vinylacetate)(EVA) foams which composed in footwear midsole. The initial bending moment of footwear was appeared at $19^{\circ}$ on bending angle of footwear, and this bending angle was not depend on thickness and hardness of midsole. The bending moments of footwear were also increased with increase of the hardness and thickness of misole which were composed in footwear. Increased hardness and increased thickness of foam and midsole also cause a greater bending moment of the sports shoe, respectively.

The purpose of this study was to analyze developed case of archiving on Mega Sport Event for searching effective method on a documentation of Mega Sport Event. In order to conduct this study, literature review method was using about book, thesis and data of internet homepage for exploring the stage on Mega Sports Event and case of Mega Sports Event record management. The field study was conducted about institute related to Olympic record management institution for analysing Mega Sports Event record management. The result of this study is following: Firstly, 2012London Organizing Committee of the Olympic Games's case(The People's Record Project) is useful to ex-ante event phase. Secondly, 2000Sydney Organizing Committee of the Olympic Games's case(Olympic Games Knowledge Management Project) is useful to event operation phase. Thirdly. LA84Foundation's case(Olympic Oral History Project) is useful to ex-post event. The significance of this study which came up with the study result above can be presented as follows. Based on the result of this study, it is assumed that three case for documentation about Mega Sports Event. Lastly, the result of this study was useful to Mega Sports Event record management institution. For the more, it will be conducted to study law of Mega Sport Event record management, humane and Material resource and method related to record management of the Mega Sports Event organizing committee.

Recently, intensive research efforts are world-widely forced on the development of sport shoes improving both the injury protection and the playing performance by taking kinesiology and biomechanics into consideration. However, the success of this goal depends definitely on the reliable evaluation of the dynamic responses of sport shoes and human foot, particularly the landing impact characteristics. It is because the landing impact force is a main source of unexpected injuries and influences the playing performance in court sport activities. This paper addresses the application of finite element method to the evaluation of landing impact characteristics of barefoot and several representative court sport shoes in running. In order to accurately reflect the coupling effect between human foot and shoes accurately, we construct a fully coupled three-diemensional foot-shoe FEM model which does not rely on the independent experimental data any more. Through the numerical simulation, we assessed the reliability of the numerical FEM model by comparing with the experimental results and investigated the landing impact characteristics, such as GRF, MIF, acceleration and frequency responses, of representative court sport shoes.

This paper focuses on the analysis of sports characteristics of e-Sports. For this purpose, it is important to set up a brand new concept of existing modern sports which is mainly concerned on physical activity. Therefore, In this paper, the researcher newly conceptualized e-Sports by following rapid change of the scene including media-technology, a change of an enjoyment method, the importance increase of sports environment and sports innovation. Also, the researcher tried to analyse how specific categorization of new sports concepts such as post-modern society, consumption & pleasure, homo-ludens, sporting experience, body and mind can be connected to e-Sports. As a result, e-Sports can be found in highly developed global society and consuming society. Furthermore, it can be defined as a 'brand new' concept of sports which features high level of psychological components in participation of activity.

This study is for a search for methods of development of marine leisure sports. As worldwide trend of marine leisure sports is developing rapidly and people more concern about their quality of life and leisure in Korea, the ear of marine leisure sports should be coming in Korea soon. This study is for a search for methods of development though the SWOT analysis. The results of the study are as below. First, the Strength of enlargement of the base in Korea are elation of concern of government and local governments, expanding local event of marine leisure sports with existing facilities and various programs. Second, the weakness of enlargement of the base in Korea are lack of awareness of marine leisure sports, frequent accident occurrence and lack of experts of marine leisure sports. Third, the Opportunity of enlargement of the base in Korea are more budget due to elation of concern of government and local governments and more preference of people in Korea. Fourth, the Threaten of enlargement of the base in Korea are low efficiency of high cost investment construction from government and local governments, huge fee of using facilities due to high cost investment construction and requiring treatment improvement of instructors of leisure sports facilities.

This paper is concerned with the numerical investigation of the transfer characteristics of the landing impact force exerted on court sport shoes to the sport surface condition. The reaction force occurred by the impact between court sport shoes and sport surface is absorbed by shoes to some extent, but the remaining impact force is to transfer the human body from the sole of a foot. We consider four surface conditions, asphalt, urethane, clay and wood court surfaces. For the dynamic response analysis, we construct a coupled leg-shoes FEM model and create the multi-layered composite surface model. The numerical simulations are performed by an explicit nonlinear finite element method. Through the numerical experiments, we examine the transfer characteristics of the landing impact force to the surface condition.

This research analyze the current status pertaining to the sport industry's information system and information network in Korea to propose integrated information network of sport industry construction measures with the goal of optimizing vertical and horizontal network formation, and knowledge information sharing and dissemination. To construct integrated information network of sport industry, literature examination and meeting of experts to search for measures are utilized. This paper analyze the realities of the sport industry's information system and information network in Korea to propose the following when it comes to the measures to realize sport industry's information integration. First, DB for sport industry relate information that factored in the Ontology is being developed. In other words, it is necessary to design a DB that factors in the Semantic Web. Second, once the DB relate to the sport industry that factored in the Ontology is developed, it is necessary to build RSS/Atom based active network that enables exchange of organic information among them.
