The purpose of this study is to provide basic information to develop a game strategy plan of a team in a future by identifying the patterns of attack and pass of national men's professional volleyball teams and extracting core key words related with volleyball game performance to evaluate game performance using 'social network analysis' and 'text mining'. As for the analysis result of 'social network analysis' with the whole data, group '0' (6 players) and group '1' (11 players) were partitioned. A point of view the degree centrality and betweenness centrality in 'social network analysis' results, we can know that the group '1' more active game performance than the group '0'. The significant result for two group (win and loss) obtained by 'text mining' according to two groups ('0' and '1') obtained by 'social network analysis' showed significant difference (p-value: 0.001). As for clustering of each network, group '0' had the tendency to score points through set player D and E. In group '1', the player K had the tendency to fail if he attack through 'dig'; players C and D have a good performance through 'set' play.

While the 7th national education curriculum is gradually proceeding, science education tries various teaching-learning method for integration in science education. The first purpose of this study is to investigate Earth Systems Education(ESE), which is approaching method to integrate science education, especially in its focus on planet Earth. Also, the second purpose is to know what the reactions of students are obtained after 'The Global Climate Game' in ESE active learning program is applied to the field. The results of this study are as follows; ESE is to propose the integrated approaching method of searching for natures and ESE teaching-learning method is to try to overcome fixed conventional teaching-learning method focus on the text book, and practical application of ESE teaching-learning method is that we can develope the student-emphasized instructional program through the discussional cooperation-teaming models, role-play instructional models. In this study, 'The Global Climate Game' found that was suitable of understanding about relating of atmosphere, hydrosphere, lithosphere and biosphere composing Earth System. Reaction of most students for ESE was showed a positive change of aspect affective region and ESE active learning program is more efficient to improve schoolwork achivement and students positive attitude toward science subject than conventional teaching-learning method. Thus if ESE active learning program is applied for a long time, the general positive attitude of students concerning science will be increased, and then the students is expected to extend the ability of application of science in their life.

Research on purchase intention had showed remarkable progress in contributing to the theory of consumer behavior. Despite the popularity of academic discussions on various issues influencing purchase intention, the mediating role of brand recall and brand attitude on purchase intention, in particular advergames, has not yet been well explored, especially in developing economies such as Malaysia. Furthermore, the influence of self-brand congruity, entertainment and brand placement acceptance as antecedents to brand recall and brand attitude are expected to add value to the brand recall, brand attitude and purchase intention relationships. This paper aims to investigate the impact of the mediating role of brand recall and brand attitude on purchase intention in advergames among Malaysian gamers. The antecedents towards brand recall and brand attitude are also examined to measure their influence on purchase intention. A total of 350 Malaysian gamers were interviewed through online survey in this study. The results showed that brand recall and brand attitude mediate the relationship between self-brand congruity, entertainment and brand placement acceptance with purchase intention. Also, entertainment and brand placement acceptance were found to have a significant relationship with brand recall. As expected, brand recall and brand attitude showed a positive relationship with consumer purchase intention in advergames. It was found that self-brand congruity has a significant influence on brand attitude and purchase intention. When users see the brand which matches with them, they tend to act positively toward the brand exposed in the game. This is consistent with Escalas and Bettman (2005) who suggested that the greater the congruity, the more positive the consumer's attitude toward the brand in question. This leads to game usage and purchase (Davis and Lang, 2013). In the advergaming context, the entertainment value in advergames is very important to determine the level of enjoyment and pleasure experienced by gamers during game-playing. Therefore, the more entertaining the ads, the more it will be remembered and the greater the positive behavior of the consumer towards the advergames - this ultimately stimulates their intention to purchase the brand. This study shows the effect of brand placement on brand recall and brand attitude and also purchase intention. Brand placements might not work in games due to the interactivity involved in game-playing as people could be distracted from noticing the brand placements (Yang et al., 2006). However, the significant influence of brand placements found in this study may provide major promise for advertisers. Game players may or may not explicitly remember the brands they see in the games, but these placements may influence their brand recall and brand attitude and could therefore influence later decisions (Yang et al., 2006). In this study, it was found that self-brand congruity was not significantly related with brand recall. The reason for this could be attributed to the fact that this study examined gamers who are highly involved in the interactive medium of games which force them to focus on game play rather than advertisements; the level of recognition to remember the brand exposed in the game is low and contributes to the "mismatch" between the gamers and the said brand. The present study contributes to the existing literature of the antecedents of brand recall and brand attitude in advergames. This study contributes to the role of brand recall and brand attitude as mediators in purchase behavior theory. Academically, the relationship between brand recall and brand attitude is well known in advergaming research, but their impact as important mediators on purchase intention add new understanding in the interactive communication literature. Their mediating role may provide new insights on how they facilitate the effects of self-brand congruity, entertainment and brand placement on purchase intention. Besides that, the studies on the influence of self-brand congruity on brand recall and brand attitude and also consumer intention to purchase had not well-investigated in advergames. This study contributes to fill those gaps in advergames literature. For practitioners, this study could suggest the use of illustrative or demonstrative placements of new products to help customers remember new brands, and the use of associative placements for existing products to increase consumers' purchase intention (Ho et al., 2011). To advertisers, this study may provide useful information to improve their current advertising strategies in games, for instance, by considering game players' congruity, entertainment value and brand placement factors.

Volleyball has become one of the world's most popular participatory sports in recent years. There are many dynamic skills and movements needed to play the game. As a result, many acute and overuse injuries to the shoulder may occur. This article addresses the common injuries and rehabilitation recommendations for the shoulder injuries in the volleyball players. The glenohumeral instability, primary or secondary impingement, internal impingement, labral injuries, and suprascapular nerve lesions are common problems in volleyball players. A basic knowledge of the biomechanics and volleyball maneuvers (blocking, serving, and spiking) can help in the development of appropriate trainging and reha- bilitation protocols. Special emphasis must be placed on the knowledge of muscular patterns involved in serving and spiking, because they typically require a strenuous unilateral action of the dominant shoulder. It is therefore impera- tive to include adequate stretching and muscular training programme for the prevention, as well as for therapy, of shoulder pain in volleyball players.

In discrete red and black, you can stake any amount s in your possession, but the value of s takes positive integer value. Suppose your goal is N and your current fortune is f, with 0＜f＜N. You win back your stake and as much more with probability p and lose your stake with probability, q = 1-p. In this study, we consider optimum strategies for this game with the value of p greater than $\frac{1}{2}$ where the player has the advantage over the house. The optimum strategy at any f when p>$\frac{1}{2}$ is to play timidly, which is to bet 1 all the time. This is called as Timid1 strategy. In this paper, we perform the simulation study to show that the Timid1 strategy is optimum in discrete red and black when p＞\frac{1}{2}.

This study is a non-structured developmental art-therapy case study having done 134 times of total treatments for a 12 years old girl, having extremely poor verbal communication ability and sociality comparing to her ability in perception and motion. I presumed the cause of this gap between perceptibility and the communication ability was a problem related to self-consciousness. To cure the problem, I provided treatment programs designed to use material which can create a stable and reliable environment and can give body experiences such as painting and play-dough. As the treatment programs progressed, I found she had changed gradually to lead the game by herself and to express her favorite colors and shapes. Also she became to be able to express her experience as a simple word and to response short answers for questions.

In discrete red and black, you can stake any amount s in your possession, but the value of s takes positive integer value. Suppose your goal is N and your current fortune is ${\Large\;f},\;with\;O<{\Large\;f}. You win back your stake and as much more with probability p and lose your stake with probability, q=1-p. In this study, we consider optimum strategies for this game with the value of p less than ${\frac{1}{2}}$ where the house has the advantage over the player. It is shown that the optimum strategy at any ${\Large\;f}$ is the DBold strategy which is to play boldly in discrete red and black when $p<{\frac{1}{2}}$. And then, we perform the simulation study to show that this strategy, which is to bet as much as you can, is optimal in discrete case.
