Recently, the size of Large Space has been gradually enlarged, according to the development of technology, and because they're used not only for indoor events, but also for various outdoor sports, for example, baseball or soccer. Therefore, there are more demands for developing indoor environment control technology to establish indoor thermal-environment which is proper for different events held in Large Space. This study aims at offering some basic data which can be referred to as the construction guide for the full-scaled construction of Large Space in Korea by arranging the matters to be attended to in designing, and controlling technologies for efficient Large Space design.

In this paper, the performance design and analysis for an Interior Permanent-Magnet Synchronous Motor (IPMSM) that will be used as a traction motor in the e-4WD system of hybrid SUV(Sports Utility Vehicle) and RV(Recreational Vehicle), are investigated using finite element method. In order to improve the accuracy of design, the tolerances of parts and assemblies as well as the material properties of permanent magnet, stator, rotor and winding etc. are considered under the conditions similar to real driving state of motor. Both no load performance test and maximum load performance test, in which real driving state and cooling condition have been considered, are also implemented via proto sample build to verify the validity of motor's performance design.

Soccer is one of the popular sports globally, and South Korea is no exception; the professional domestic soccer tournament has been held in South Korea since 1983. The national soccer team in South Korea has shown outstanding performances, hosting the 2002 World Cup and achieving a bronze medal at the London 2012 Olympic Games and second place at the 2019 U-20 World Cup. In addition, one of the South Korean soccer players, Heung-min Son, has played a remarkable role in the English Premier League. Like other global soccer clubs, South Korean domestic soccer clubs create and manage their own YouTube channel to interact with fans and keep them updated. In this study, we explore how and why Seoul E-Land Football Club (SEFC) utilizes its YouTube channel. SEFC is distinctive in that they are playing at the second division, their home ground is based in Seoul, and they are sponsored by a company run on Christian values. We analyze one of the soccer club's YouTube channels multi-dimensionally and discover the roles of YouTube.

현재는 온라인을 통해 개인이 직접 방송을 제작하는 형태의 1인 방송이 가능한 시대이다. 스마트폰을 이용하였을 경우 방송할 만한 충분한 환경이 마련되지 않아도 비교적 간단하게 중계 시스템을 구성할 수 있다. 본 논문에서는 최근 하나의 문화이자 대중 스포츠로 자리 잡은 E-스포츠의 게임 유저들이 스마트폰을 활용해 게임에 쉽게 참여할 수 있는 중계 시스템 구현을 제안한다.

최근, e-스포츠, e-게임을 포함하는 e-레저를 위한 새로운 콘텐츠가 요구되고 있다. 이러한 요구로 사람을 추적 대상으로 하는 e-레저용 모바일 AR 연구가 진행되고 있다. e-레저 모바일 AR은 실외환경에서 사용되기 때문에, 원거리에서의 추적 성능이 중요하다. 그러나, snow, snapchat 등과 같은 기존 모바일 AR은 원거리에서 추적 성능이 낮은 단점이 있다. 따라서, 본 논문에서는 실외환경에서의 e-레저 모바일 AR을 제안한다. 제안된 e-레저 모바일 AR은 색상 마커 및 인체비를 이용하여 실외환경(원거리)에서 머리의 위치를 추적하고, 추적된 위치에 가상의 객체를 증강한다. 제안된 e-레저 모바일 AR의 성능은 추적 성능 및 연산 시간의 측정 실험을 통해 검토되었다.

본 연구는 이용과 충족 이론을 적용하여 e스포츠 직접관람자의 관람동기, 관람만족, 행동의도의 주요 변수 간 관계를 실증 분석하였다. 탐색적 요인분석 결과 기존의 주요 관람만족 동기 중 8개의 스포츠동기, 3개의 팬동기와 한 개의 관람촉진 동기가 e스포츠의 직접관람동기로 확인되었다. 그리고 직접관람자의 관람동기 중 오락, 팀애착, 경기기술, 선수매력, 심미성 동기요인은 관람만족에 유의미한 영향을 미치고, 행동의도에는 사회교류와 오락요인이 영향을 미친다는 것을 확인하였다.

본연구는슬관절과견관절의초기재활과정에서관절운동범위와스트레칭, 그리고유산소성운동프로그램에대한논문이다. 만약관절이손상후장기간동안고정된다면관절이굳어지고 근육은위축이 될것이다. 그러므로본 프로그램은다양한운동기술을포함하고있다. 즉관절의경직을예방하기위한운동범위확보와근육의이완을위한스트레칭, 심폐기능의감소를예방하기위한심혈관훈련(수영, 상체자전거, 고정식자전거)을포함하고있다. 초기재활과정에서는임상운동전문가와환자사이의상호관계를형성하는것이매우중요하다. 또한임상운동전문가는환자의통증과운동적응도, 체력수준, 프로그램의진행등에관해스포츠의학전문의와상의하는것이권장된다.

The purpose of this study was to assess the metabolic profile and nutrient intake data in Korean adolescents according to exercise regularity using the forth Korean National Health and Nutrition Examination Survey from 2008 data. A total of 834 Korean adolescents (440 boys, 394 girls) aged 12 to 18 years were classified into exercising male (EM), non-exercising male (NM), exercising female (EF), and non-exercising female (NF) groups. EM exhibited significantly higher weight (P<0.001), waist circumference (WC) (P<0.01) and body mass index (EMI) (P<0.001) than NM. EF showed significantly greater height (P<0.01), weight (P<0.001), we (P<0.001), and BMI (P<0.001) than NF. Although ratios of macronutrient intake were within the appropriate range in all groups, energy, riboflavin, vitamin e and calcium were assessed as in adequate by the nutritional adequacy ratio (NAR) in all groups. Moreover, EF and NF had inadequate intake of vitamin A and iron according to NAR, respectively. There were significant correlations between height and NAR protein (r=0.249, P<0.001), and mean adequacy ratio (MAR) (r=0.177, P<0.01), and between weight and NAR protein (r=0.180, P<0.01), and MAR(r=0.136, P<0.05) in EM. On the other hand, there were significant correlations between weight and NAR protein (r=0.270, P<0.01), we and NAR protein (r=0.271, P<0.01), and BMI and NAR protein (r=0.326, P<0.01) in NM. There were significant correlations height and NAR Fe (r=0.153, P<0.05) in EF. However, there were no significant correlations between metabolic factors and nutritional adequacy in NF. Although we noted no significant differences in MAR between the groups, the exercising groups showed higher MAR values than the non-exercising groups. Therefore, practicing of ideal dietary behaviors appears to be induced through physical activity and regular exercise in Korean adolescents.
