e스포츠 유형별 게임몰입과 게임중독이 체육활동 관여도에 미치는 영향
박병일(Byung Il Park),조환우(Hwan Woo Cho) 한국사회체육학회 2009 한국사회체육학회지 Vol.0 No.37
This study was to analyze sport activity involvement effects of the online game flow and addiction according to the e-sports type and provide an overview of the solution that the e-sport`s problems related to join in the Korean Amateur Athletic Association, and negative point of view about violence and addiction at the online e-sports game. The subject of this study were 599 middle school students, high school students and undergraduates in Seoul, Gyeonggi area. The sample divided into sport type e-sports and non-sport type e-sports groups and compared to online game flow, online game addiction and sport activity involvement. To analyze materials reliability and correlation analysis, EFA, CFA and SEM were used as statistic analysis techniques. Results of this study were as following. First, online game flow of the whole sample has positive influence on sport activity involvement and online game addiction however, online game addiction has negative influence on sport activity involvement. Second, online game flow of the sport type e-sports group has positive influence on sport activity involvement, but online game addiction has negative influence on sport activity involvement. the online game flow has not influence on addiction. Third, online game flow of the non-sport type e-sports group has positive influence on sport activity involvement and online game addiction. The online game addiction has not influence on sport activity involvement. The results show that participants in the sport type e-sports more related to sport activity involvement than non-sport type. Accordingly, e-sports organization have to invigorate sport type e-sports.

Thick-to-Thin 형 변후경계를 가지는 겹판스프링용 SPC5A 강의 피로균열성장 거동에 관한 실험해석
이환우,이갑래,조진연 경남대학교 신소재연구소 1992 論文集 Vol.2 No.-
본 연구에서는 차량용 겹판 스프링의 소재로 쓰이는 SPS5A강의 변후재에 대한 피로실험을 통해 피로성장 특성을 파악 하였으며, 변후재의 응력강도계수를 실험적으로 구할 수 있는 방법을 제시하였다. thick-to-thin형 변후재에 대한 피로수명 Cycle수는 균후재보다 작으며, 변후경계 근방에서는 어느정도의 균열성장둔화 현상을 보였다. 그러나, Thick-to-thin형 변후재의 변후경계 근방에서의 균열성장감소현상이 나타나지 않는 임계 변후형상비가 존재함을 볼 수 있다. This thesis showed the characteristic fatigue crack growth in the SPS5A steel plate with the thick -to- thin type discontinuous thickness interface, and determined the stress intensity factor of discontinuous thickness plate by the fatigue test results. The fatigue life cycles of thick -to-thin type discontinuous thickness plate are shorter than the uniform thickness plate, but fatigue crack growth rate(da/dN) is decreasing at the nearby discontinuous thickness interface. Also we shall know the critical thickness ratio which does not have the dereasing phenomenon at the nearby discontinuous thickness interface from experimental results.
