This paper studies on the instability behaviour of the Seoul southwest baseball dome. The nonlinear Snapping phenomenon of the structure is investigated about the load mode by the design load of analysis structure and these combined loads. The initial imperfection obtains the buckling mode through the eigenvalue analysis of the tangential stiffness matrix and uses this for the nonlinear analysis. However, the buckling of members or the local buckling, and etc don't consider in the research range of this research task. Also it is limited the overall buckling phenomenon.

While many games have been published that are used with input-devices such as a mouse and keyboard, the number of games that can recognize the behavior of a human utilizing devices such as Kinect and Wii has increased. In this paper, we present the development of a baseball game that utilizes a Leap Motion Controller. A Leap Motion Controller recognizes accurately the movement of a user's fingers. Our implemented game consists of characters, a background and animation. It is a moving animated game in which the users play a game in point of view of a third person. The major feature of our game is that the game players can enjoy the game using a Leap Motion Controller.

Among lots of sabermetric statistics for baseball batters' ability, the wins above replacement (WAR) is the most popular statistic in MLB. However, there exists a difficulty applying WAR to KBO, since KBO data do not have position adjustment, league adjustment and park factor which are essential in calculating WAR. In this paper, using five statistics for both KBO and MLB qualified batters, we propose hitting ability index (HAI), an alternative sabermetric indices to represent batters' ability. Comparing HAI with WAR of MLB batters, we evaluate the validity of HAI and then applied HAI to 2015 KBO data in which HAI is analyzed statistically with respect to different teams, ages, and positions. Moreover, the linear relationship between KBO batter's HAI and their annual salary is discussed. Grouping 46 KBO batters based on confidence region of the regression model for annual salary, we also statistically investigate batter's annual salary in these groups with respect to several factors.

본 논문에서는 스포츠 경기장에 경비 로봇의 안전대책에 관하여 위험성평가를 진행하였다. 스포츠 경기장에서는 다양한 형태, 종류의 이벤트가 진행되고 있다. 안전관리를 위한 안전 요원이 반복 순찰을 진행하고 있으나 대형 규모의 경기장의 경우 안전 요원이 전체적인 안전을 확인하고 책임지기 어렵다. 또한 스포츠 경기장에서 일어나는 대부분의 사고는 군중 관련 사고이다. 사고 예방을 위해 안전 관리자의 역할을 보조하는 로봇을 활용하여 사건 및 위험 상황에 대비하는 시스템의 구축이 필요하다. 스포츠 경기장 경비 로봇 안전 운영 안전대책 도출을 위해 선행연구와 참고문헌을 바탕으로 경비 로봇의 규제 및 특성을 탐구하여 연구를 진행했으며 경기장 답사를 위해 잠실 종합운동장 야구장을 3회 실사하여 위험한 사건이 일어날 수 있는 장소를 조사 하였으며, ISO 13489-1에 적용된 PLr 트리를 통한 위험성 평가를 진행하였으며 자체 위험성 평가 시트를 제작하여 위험 정도를 도출 하였다.

The purpose of this study is to clarify the relationship between servicescape experience of visitors to professional baseball stadium, control perception on the spot, consumption emotion, and revisit intention. A total of 273 questionnaires were analyzed using SPSS 20.0 and AMOS 20.0. The validity of the data was verified through frequency analysis, reliability analysis, confirmatory factor analysis, and correlation analysis. The hypothesis was verified by structural equation model analysis. First, servicescape has a statistically significant effect on control perception. Second, the control perception in the servicescape has a significant effect on the consumption emotion. Third, servicescape effected consumption emotion. Fourth, consumption emotion had a significant influence on the revisit intention. The results of this study suggest that visitors to baseball stadiums can induce revisit intention through positive experience of servicescape. The specific discussions and implications are described in the text.

The purpose of this paper was to analyze a social discourse on the construction of a domed stadium produced in the media. In particular, the article sought to explore and interpret the political, economical, social and cultural contexts of the building of a domed stadium by looking at how media sources with newspapers as the central source of information have produced and formed social discourses regarding the construction of a domed stadium. In a concluding perspective it was confirmed that the three aspects of social discourses have been produced and formed. First, a 'approval' discourse supporting the building of a domed stadium has been produced and formed. Second, a 'opposite' discourse criticizing it has been produced and formed. Third, in the confrontation between the approval and opposition of the building of a domed stadium, a 'governance' discourse, which the construction of a domed stadium should be solved rationally through the communication and involvement of the private and governmental sectors, has been produced.
