The interrelation between abusive game designers and players are revealed and considered as one of the game arts by Miguel Sicart. This study is based on the frame analysis of Ervin Goffman. The player centered game design, in the case of a digital game, is penetrated into the frame, and player's experience and game frame at the same level can be assumed as positive down-keying. Conversely, confusion of the game is experienced by the players and perceptions about the games are required. The term of Miguel Sicart, generated the abusive game design in the view of the game art, considers both common game and design of the game, respectively. Nevertheless, the abusive game design refreshes the reflections of players in a game and presents possibilities of bridging the designs of standard games through the techniques and devices.

The study is conducted to investigate the prevalence of a yips phenomenon in high school baseball players and provide the basis of its origin and an effective treatment intervention. Therefore, we survey 320 high school baseball players registered at Korea Baseball Association, excluding poorly answered 30 questionnaires. Utilizing PASW 20.0, the analysis of yips experiences and a coping method is carried out with descriptive statistics and ratio analysis. The results from the process above are as follows. The ratio of high school baseball players who experience yips reaches 64%, which is significantly high; experiencing yips, they have both physical and psychological problems; although they would have psychological trainings, few of them work, which implies that the discussion on yips prevention and coping methods for high school baseball players is imperative.

The purposes of this study to provide quantitative data in necessary to advance techniques kinematic analysis of Cucarachas which is an action of Rumba. Then, this study is performed on 5 female players who have won within the third prize at a national athletic meeting. When whole foot reached to floor, Displacement of right-left hip joint (until $E1{\sim}E3$ average moved 15.15cm)is found at right-left direction since the hip joint is turned to right back. On the other side, large displacement is shown because Rumba Cucaracha Movement is expressed by maximum shift of hip joint to right and left direction. Displacement of right hip joint(E3$57.40{\pm}7.46$) is found in front and in rear direction since hip joint is moved in rear and in front to turn the hip joint. It may be stated that this is ideal displacement expressed by movement of whole body with artistic poise and presentation because role of hip joint is very important in technical and artistic side. Angle of right shoulder joint E2($105.44{\pm}9.64$) is got wider. It may be stated that player shifts up and abduct elbow joint to right since center of gravity of player is exceedingly shifted to right in this motion of Cucarachas. On the other hand, since this motion is abducted right elbow and shrunk external abdominal oblique to him center of body to left front of hip joint, the angle becomes narrow. It is shown that angle of knee in right knee joint E4($75.44{\pm}2.61$) is large since right leg and hip joint is turned by foot using reaction of ground and so center of body is shifted to left. Large angle of ankle E4($134.40{\pm}10.50$) in Cucaracha Movement is shown by the action of twist force using narrow part of foot and compression force against ground with adduction speed of arm. The various kinematic analyses associated with motions of dance sport have not been sufficiently peformed so far, and thus a number of research projects for dance sport should be proposed and performed to be continuous.

Although the history of the game of Go is more than 2,500 years, the theoretical studies of Go are still insufficient. In recent years a lot of studies using Artificial Intelligent(AI) have been conducted, but they do not provide the prominent theoretical reality. We applied Principal Component Analysis(PCA) to the professional Go openings, which are the early stage in Go, to analyze them especially focused on the Go game records of the professional 9-dan player Lee Sedol who is the world's top professional Go player. The results showed that among the 361 eigenvectors the 48 most significant eigenvectors capture most of the variance (99.9%) and the 30 most significant eigenvectors enable to possess 90.5 percent of the total variance. This result would be expected to considerably contribute to pattern recognition research of the professional Go openings in the near future.

The objective of the study is to develop a variety of different indices based upon the detailed data obtained through the computer input/analysis program developed recently. Through this new program, all the activities of players can be recorded on a real time basis and they can be analyzed statistically with different types of outputs. Therefore in this research, with the help of the database program, we will develop the indices for teamwork, goal making ability, offense/defense ability, individual player's contribution to the game, and various game related performances.

디지털 방송 서비스가 보편화되면서 MPEG-2, DVB 및 ATSC Transport Stream의 사용이 확산되고 있다. 수신된 방송 Transport Stream(TS)은 TS 그대로 이용하거나 Program Stream(PS)로 변환한 후 저장하여 이용한다. DVD같은 디지털 저장매체에는 PS가 사용되므로 디지털 방송을 수신하여 이를 DVD나 DVD-RAM과 같은 저장 매체에 저장하려면 TS를 저장용 Stream인 PS로 변환하여 저장하여야 DVD Player와 같은 매체 재생기에서 이를 이용할 수 있다. 본 논문에서는 TS를 PS로 변환하고 변환된 TS와 PS를 분석하여 얻어진 변환 및 변환 후의 여러 결과들을 비교 분석하여 보여준다.

본 논문에서는 3차원 영상의 생성 원리와 3차원 영상 모드 그리고 기존의 3차원 영상 재생 장치를 분석하였다. 3차원 영상 모드에는 interlace page-flipping, sync-doubling 모드가 있으며, LCD(Liquid Crystal Display) shutter glasses를 이용한 3차원 영상 재생 장치의 동작 원리 및 파형을 분석하였고 현 재생 장치의 장. 단점을 논하였다 이 장비는 심한 flicker를 유발하였고, 완전한 3차원 입체 영상의 효과를 얻을 수 없었다. 마지막으로 LCD 모니터용 3차원 영상 재생 장치의 필요성과 향후 연구 방향을 제시하였다.

Knowing what factors into a player's ability to affect the outcome of a sports game is crucial. This knowledge helps determine the relative degree of contribution by each team member as well as sets appropriate annual salaries. This study uses statistical analysis to investigate how much the outcome of a professional baseball game is influenced by the records of individual players. We used the Lotte Giants' data on 252 games played between 2007 and 2008 that included environmental data(home or away games and opponents) as well as pitchers' and batters' data. Using a SAS Enterprise Miner, we performed a logistic regression analysis and decision tree analysis on the data. The results obtained through the two analytic methods are compared and discussed.

Cluster analysis is one of the useful methods to find out number of groups and member’s belongings. With the rapid development of computer application in statistics, variety of new methods in clustering analysis were studied such as EM algorism and Self organization maps. The goals of cluster analysis is finding the number of groupings that are meaningful to me. If data are analyzed perfectly with cluster analysis, we can get the same results from discernment analysis.

A Precise actuator in the pick-up of a DVDR/P(Digital Video Disk Recorder/Player) is required to control position accurately. Therefore, in order to develop a reliable actuator, dynamic characteristics of each part in an actuator should be examined closely. This paper presents systematic design process of an actuator using various analysis methods to confirm fundamental capability and solve performance problems related to dynamic characteristics of an actuator beforehand. Particularly, sensitivity analysis is presented through the program using mass moment of inertia and general equations of rigid body. Through the result of sensitivity analysis, important inferiority causes of actuator are selected and reduced. In the end, dynamic characteristics of manufactured actuators are improved considerably.
