The Youth Olympic Games(YOG) is an international multi-sport event first held in Singapore from August 14 to August 26, 2010. The idea for such an event was introduced by International Olympic Committee(IOC). The Federation of International Gymnastics(2009) designed the Code of Points and regulates for junior gymnastics at this time. The purpose of this study was to give crucial information and adapt to coaches and junior gymnasts at the time of changing code rapidly. For this study, The eight finalists rings exercise at the 1st Youth Olympic Games was recorded using a digital camcoder. The exercise contents analysis of rings was carried out by an experienced international judge using Code of Points(FIG, 2009). The C elements in various difficulties were performed the highest frequency. The elements group I was the most frequently performed in overall difficulties. Moreover, All the gymnasts performed the elements of the Jonasson and Yamawaki in Group I. Therefore, junior gymnasts need to consider Jonasson and Yamawaki elements correctly in elements group I. The 1st ranked ROU(132) gymnast performed high difficulty value for his routine with the highest E score(9.050). The average of D score were 5.125. In the E scores, 8th USA(140) gymnast received the lowest E score of 8.15, 5th MGL(127) gymnasts received the fewer E score of 8.475. Coaches and junior gymnasts should try to increase D score above 5.125 by higher swing elements in Group I and II as well, decrease deduction of elements in exercise contents.

The purpose of this study is to analyze the success and failure of the movie made by the original game by comparing the box office environment of the movie made by the original game and to derive the necessary elements to make a good original movie. The specific analytical content studied the specific successes and failure factors of the remake of the game with , , and . Analyzes of the research show that the audience can be divided into game fan and non - game fans, and how to reflect the expectation on both sides of the movie is an important factor in making the movie. Also, games of different styles and genres from other themes can not be created in the same way as remixing movies, but flexible diversity and management are needed. Unconditional scenarios of games or game switching of movies can not be popular among the public, and it is very important to analyze specific target audiences.

In this study, by both qualitative and quantitative measurement on the purpose of deriving the sensitive amusement factor. I consider the fear of horror games as "the amused fear" and analyze it, which is based on the play theory by Roger Caillois. On the basis of this, I classified the amusement fear in horror games into the 4 factors. I conducted some positive tests through the player's response in order to verify them. The test is conducted measuring the heart rate of each experimenter by cardiometer while they are playing horror games. By analyzing the video data, I gave a name to the point that the amusement fear factors are expected to influence psychologically and physiologically as the fear point. At this point, I examined if the measured heart rate makes the outstanding difference or not, when compared average heart rate with experimenter's heart rate. In addition, I also examined if there is a statistical correlation of heart rate by attaching player's subjective data through the questionnaire. Consequently, it was statistically turned out that the experimenter's heart rate which is measured rose dramatically than usual, and that there are close correlations among subjective data. I also found out that the amusement fear factor at the relevant point plays a major role in experimenter's psychological and physiological response. In this study, I could prove the horror factor as a meaning of amusement factor using both theoretical method and positive method establishing a standard set that is helpful for further production and planning of the game.

The purpose of this study is basic data for developing baseball uniform in the future by carrying out a survey of amateur baseball players on the wearing pattern of uniform and inconvenient details. To do this study, a survey targeting 307 male social baseball players in their 20s to 40s was conducted, and a preliminary survey through interview with designers, MDs and patternmakers had also been carried out and analyzed prior to the main one. The result shows that armpit and back patches get wet with perspiration the most, and patches around knees are likely to be worn out because of frequent sliding. Thus, they are dissatisfied with poor protective function the most and need quilted pads around knees. Answers for a question on injuries during games indicates that shoulder injuries due to pitching or batting and abrasion owing to sliding are most common and knee injuries are also frequent. As for the wearing satisfaction of uniform, they want elasticity and breathability of textile to be improved; they are not satisfied with its design and fit because they think top and bottoms are much too long and uncomfortable; they often find dirt inside of the uniform during games. Besides, they find it very difficult to remove dirt from the uniform even after washing. There has been a growing population of amateur baseball players over recent years, so this study would help develop functionally improved uniform and be used for developing uniform for professional baseball players.

The traditional theories of games are based on an assumption that the payoffs have a single dimension. In reality, any alternative is likely to imply more than one payoff. This paper deals with the game against nature with vector payoffs. The purpose of this paper is to develop methods for finding the practical optimal strategy in the game against nature with vector payoffs. Under the assumption that a prior probability over the stats of nature is given, this paper shows that a practical optimal strategy in this game can be obtained by applying a entropy method in order to assess the payoff weight and by employing the concept of compromise solutions in order to reduce the non-dominated solutions. When subjective payoff weights are unknown as well as known, these methods can be used. A numerical example is given.

In this paper, we would like to test whether the hit at a particular bat has a dependency with the hitting results at the previous bats in professional baseball games. For this purpose, we used the 2011 Korean Baseball League data. We find out that the hitting percentage at a particular bat has no dependency with the hit at the previous bat, after reviewing the conditional probability of hit at each bat and the lift. From the independence test of hits at consecutive bats, and hit at a particular bat with no hits at previous bats, we can conclude that hits at particular bats are not dependent on the hits at previous bats in most cases. Hence, we can safely conclude that a hit at a particular bat is statistically independent from the hits at the previous bats.

Purpose: The purpose of this study is to find which variables among impulsiveness, aggression, and emotional intelligence can predict the game addiction of elementary school students best. Method: We conducted the present study during the period from April 15, 2004 through June 5, 2004. The subjects of this study were elementary school students chosen from three elementary schools in the Daejeon area. The subjects were selected randomly from 4th, 5th, and 6th graders in those schools. The number of subjects selected was 601. The measurement tools used were the general information questionnaire, computer game addiction scales, impulsiveness scales. aggression scales, and emotional intelligence scales. The data was analyzed using the SPSS statistics program. Results: The mean score of the students was 49.94 on the computer game addiction scale. 56.17 on the impulsiveness scale, 141.19 on the aggression scale, while the mean score of the students on the emotional intelligence scale was 162.78. Various factors were significantly different in the levels of computer game addiction: grade (F=7.343. p=.000). sex (t=6.352. p=.000), school record (F=4.263. p=.004), parents' computer use (F=4.097. p= .008), history of playing games (F=10.739. p=.000), frequency of playing games (F=61.254. p=.000). and number of computer game titles (F=61.673. p= .004). The computer game addiction had significant correlations with impulsiveness (r= .401. p=.000), aggression (r=.612. p=.000). and emotional intelligence (r=.536, p=.000). All three factors of impulsiveness, aggression, and emotional intelligence affected the level of game addiction. Among these factors. the aggression affected the level of addiction the most. Conclusion: These results will help the development of a systematic program for the prevention and treatment of computer game addiction by clarifying the effects of the computer game addiction upon the elementary school students' impulsiveness, aggression, and emotional intelligence.
