The purpose of this study was to analyze the weight transfer patterns under the different golf swing types which are full swing control swing and putting stroke. Two women golfers participated in this study, one(165cm, 94.3kg)being classified as a low-handicap(LH)player, the other(165cm, 54.5kg) being classified as a high-handicap(HH) player. Both players are right-handed. Two force plates(Kistler, 9286AA) were synchronized with a motion capture system(Qualisys ProReflex MCU240). Anteriorposterior, mediolateral, and vertical forces were used as an indicator of the pattern of swing. Four discrete positions which are address, top of backswing impact, and finish were identified as an event and three phases which are backswing downswing, and follow-through between he events were also identified. The results showed that, at impact, the total force was 1.24BW ring the full swing 1.17BW during the control stroke, 1.00BW during the putting stroke. Depending on the golf swing types, the differences are existed. At impact, the distribution of forces is different with a low-handicap(LH) player and a high-handicap(HH) player. A LH player has 26% in right foot and 74% in left foot during the full swing 49% in right foot and 51% in left foot during the control swing 49% in right foot and 51% in left foot during the putting stroke. A HH, on the other hand, has 74% in right foot and 26% in left foot during the full swing 62% in right foot and 38% in left foot during the control swing 54% in right foot and 46% in left foot during the putting stroke. From address to top of backswing the amount of vertical forces are changed 43:57(right foot: left foot) to 76:24 during the full swing 47:53(right foot: left foot) to 75:25 during the control swing 50:50(right foot: left foot) to 54:46 during the putting stroke. The biggest weight transfer pattern took place in full swing and the control swing is next, and the putting stroke is the final.

In the present analysis, the buckling behavior of smart beams integrated into racket frames for enhancing player control was examined by numerical solutions and sinusoidal shear deformation theory. The smart beam under consideration is subjected to an external voltage in the thickness direction. The integration of this smart material into the structure of the racket should optimize performance, improving the racket's stability and responsiveness during play. In this, an accurate representation of complex shear effects is made by using a sinusoidal shear deformation theory, while the solution of the resulting governing equations is made by numerical methods. The critical buckling loads and the characteristics of deformation obtained through the analysis provide insight into some design parameters controlling and influencing stability. Obtained results are validated with other published works. The length and thickness of the beam, elastic medium, boundary condition, and influence of external voltages have been represented for buckling load in the structure. These results will help in designing smart racket frames using smart beams to provide more precision and control for the players in an intelligent way.

본 연구는 모바일 RPG에서 게임 시스템으로 삽입된 자동전투 기능의 플레이어 욕망 충족 양상을 살펴보고자 한다. 이를 위해 먼저 자동전투의 유형을 활성화 시점과 플레이어 개입 정도를 기준으로 '부분적 자동전투'와 '완전 자동전투'로 분류한다. 이후 유형별 플레이 양상을 도출하여, 플레이어의 욕망의 대상을 라캉(Lacan)의 욕망이론을 바탕으로 살펴보았다. 이를 통해 부분적 자동전투에서 플레이어는 완벽한 조작을 통해 더욱 높은 단계를 공략하고 싶은 욕망을 가지고 있었으며, 욕망의 대상은 전투지의 난이도가 된다. 반면 완전 자동전투에서의 플레이어는 게임의 규칙을 완벽하게 이해하고, 전투지 공략 이후 획득할 수 있는 보상을 통해 더욱 강력한 캐릭터를 가지고 싶은 욕망을 가진다. 플레이어가 욕망의 대상을 획득하고 나면 그것이 허상이었다는 것을 알게 되고 새로운 욕망의 대상을 찾아 추구하게 된다. 이 과정에서 자동전투는 욕망의 대상을 획득하려는 주체의 적극적인 행위로서 사용된다.

The method of operating a game could determine the psychological distance between the player and the game character, and thus, in the Virtual Reality, players' control methodologies are important to enhance their immersion. This study has the objective of examining the difference in games according to the method of operation based on the player's movements. This study researched the effect of the method of operating movement conforming to the movement of the character and the physical operation of the body on forming game experiences for the player. The result of performing an experiment increased reality for the game player through a controller in the shape of the actual control, to increase focus in the game. As so, game play through movements, including actual movements by the player displayed to enhance game satisfaction. In the part of media remediation field, Game can be defined as media which has their own unique hypermediacy. Especially, in the motion based game, players' movement mediates players and the game, therefore, players' movement could make players' experience augmented or immediate in accordance with the characteristics of movements. Even though sports and dances genres of motion-based games are common, RPG or adventure genres are rare. It can be explained that the characteristics of the action have been explained in the immediacy. In a game of fantasy, which is difficult to experience in real-life situations, the nature of the player's motion can increase the immersion of the game, which can contribute to utilization of players' motion and experience design in the various genres and suggestion of grounds theory. In addition, through this study, it is able to design motion-based games of various genres.

On the website r/NYYankees, a sub-forum ("subreddit") of Reddit is devoted to the Major League Baseball team New York Yankees, with its predominantly male users showing their appreciation for baseball heroes by expressing erotic desires towards the players. When a player performs well, the subreddit is filled with admiration of desires to become the player's intimate lover-explicitly expressed by "male" fans. This paper explains the phenomenon of young male fans' desire for the now-lost model of traditional masculinity of domination and control, displayed in the context of baseball players' dominant performances. The discrepancy between a fan's non-homosexual real-world self and his homoerotic language on the subreddit is explained using the "performative fandom" theory, developed by Osborne and Coombs borrowing Butler's notion of performativity. This paper suggests how this desire for traditional masculinity serves as recognition to the collapse of masculinity in the modern American society.

Cognitive Radio network (CR) is a promising paradigm that helps the unlicensed user (Secondary User) to analyse the spectrum and coordinate the spectrum access to support the creation of common control channel (CCC). The cooperation of secondary users and broadcasting between them is done through transmitting messages in CCC. In case, if the control channels may get jammed and it may directly degrade the network's performance and under such scenario jammers will devastate the control channels. Hopping sequences may be one of the predominant approaches and it may be used to fight against this problem to confront jammer. The jamming attack can be alleviated using one of the game modelling approach and in this proposed scheme stochastic games has been analysed with more single users to provide the flexible control channels against intrusive attacks by mentioning the states of each player, strategies ,actions and players reward. The proposed work uses a modern player action and better strategic view on game theoretic modelling is stochastic game theory has been taken in to consideration and applied to prevent the jamming attack in CR network. The selection of decision is based on Q learning approach to mitigate the jamming nodes using the optimal MDP decision process
