There is a common misbelief that female gamers prefers simple cute easy games so that they are incompetent if higher skill level is required or disqualified to be a winning party member in MMORPG. This pink game theories are the results of video game analysis done in US and Europe way before online games and mobile games become popular thus. there are many evidences that such misconceptions do not hold anymore. However, researches on gender game culture and gender preferences have not been seriously conducted since 2007 in Korea. Thus, in this paper, we surveyed 88 male and 151 female gamers from their late teens to 30s and found a gap between behavior and perception due to serious gender stereotypes. Gender differences are still found in several areas, but the degree of differences were weakened or in different direction from 2007. The game design to attract female gamers should understand such gender gaming culture and gender difference.

Steel encased composite columns have been used for buildings and piers of bridges. Since the column section for the pier is relatively larger than that of building columns, economical steel ratio needs to be investigated for the required performance. Composite action between concrete and embedded steel sections can be obtained by bond and friction. However, the behavior of the column depends on the load introduction mechanism. Compression can be applied to concrete section, steel section and composite section. In this paper, experiments on shear strength of the steel encased composite column were performed to study the effect of confinement by transverse reinforcements, mechanical interlock by holes, and shear connectors. Bond strength obtained from the tests showed considerably higher value than the design value. Confinement, mechanical interlock and stud connectors Increased the shear strength and these values can be used effectively to obtain composite action of Steel Reinforced Concrete(SRC) columns.

In an RFID network consisting of a single reader and many tags, a framed and slotted ALOHA, which provides a number of slots for the tags to respond, was introduced for arbitrating a collision among tags' responses. In a framed and slotted ALOHA, the number of slots in each frame should be optimized to attain the maximal efficiency in tag cognizance. While such an optimization necessitates the knowledge about the number of tags, the reader hardly knows it. In this paper, we propose a tag cognizance scheme based on framed and slotted ALOHA, which is characterized by directly taking a Bayes action on the number of slots without estimating the number of tags separately. Specifically, a Bayes action is yielded by solving a decision problem which incorporates the prior distribution the number of tags, the observation on the number of slots in which no tag responds and the loss function reflecting the cognizance rate. Also, a Bayes action in each frame is supported by an evolution of prior distribution for the number of tags. From the simulation results, we observe that the pair of evolving prior distribution and Bayes action forms a robust scheme which attains a certain level of cognizance rate in spite of a high discrepancy between the Due and initially believed numbers of tags. Also, the proposed scheme is confirmed to be able to achieve higher cognizance completion probability than a scheme using classical estimate of the number of tags separately.

This study has verified the process of helping actors recognize their sexual problems linked to sexual violence cases through early sexual experience history, and exploring and insighting the stuck feelings of sexual violence actors through psychodrama, which focuses on expressing behavior and emotions. The research questions were divided into sexual violence cases and perceptions of actors, actual insights through psychodrama, and dealt with past biblical history related to actors' events and events, exploration of childhood trauma, and insights and changes in emotions through psychodrama. The results from the study are as follows. First, they showed low self-understanding levels and frequent use of defense mechanisms against sexual violence cases in an environment related to cases involving sexual offenders, and were aware of the problematic factors affecting the cases in the course of their daily lives, but did not take them seriously. Second, there were many distorted masculinity and adult sites related to participants' biblical experience history. In the early experience of sexual activity, it was often viewed as a sexual object rather than an emotional exchange with a lover, and the contents of the initial Bible experience were linked to actual sexual violence cases committed by participants. Third, childhood trauma of participants through psychodrama led to rapidly changing family circumstances and abuse by fathers. Fourth, the actual content of emotions represented by anger in the early stages of psychodrama is meaningful in that it revealed the process of sadness, pain, regret and longing for a departing mother leading to objective insight into emotions through the catharsis process.

The purpose of this study is to provide a basis for the sustainability of cooperatives, To provide theoretical support for healthy development and academic research. The purpose of this study is to improve people's understanding of cooperatives (farmer professional cooperatives) in China. First of all, we analyze the background and concept of the introduction of cooperatives and the use of the latest advance research in China and South Korea; Secondly, we propose the status of Chinese cooperatives and the growth process of the legal system; Thirdly, we focus on the law and system of Chinese farmer professional cooperatives. Therefore, this study proposes the following four enlightenments : First, China should continue to improve and improve its legal systems, such as the tax assistance legal system, financial preferential legal system, and technical assistance legal system. Secondly, it is necessary to strengthen government supervision of cooperatives, improve the internal system of farmer cooperatives, improve the financing policies of farmer cooperatives, grasp the relationship between development and regulation, and form a development model centered on farmers. Third, the development of farmer cooperatives must be integrated with the local culture. Fourth, we must strengthen the training of cooperative members and strive to improve the level of management and self-innovation.

This paper compares the underpricing of IPOs listed on KOSADQ with that of IPOs listed on KSE. When we consider the last day of upper price limit of IPOs, IPOs on KSE show higher initial excess return than IPOs on KOSDAQ. And AR2 which is the abnormal return based on the stock price of the last day recording upper limit after listing, IPOs on KOSDAQ exhibit larger abnormal return than IPOs on KSE. Our study also reports that the long-term performance of IPOs in two markets does not show any difference. That is, IPOs of both markets under performed in the long-run. The wealth relatives of IPOs are a little higher than market portfolio. We explored the reasons of the underpricing of IPOs in both markets through the multiple regression analysis. The business history is examined asstatistically significant variable to explain the underpricing.

The student's pre-questions (pre-class questions related to the learning contents) not only provide the teacher a gauge of the interest and level of the student, but also provide a useful means of providing clues to proceed with the teaching-learning process. The purpose of this study is to develop an analytical framework for effectively analyzing students' pre-questions and to analyze students' pre-questions related to elementary science learning unit of the 2009 revised curriculum by applying this framework. The developed framework is composed of three major categories: knowledge type, extended type, and curious type, each of which is then subdivided into several sub-categories. Using the developed analysis framework, 914 pre-questions from the students presented in the $5^{th}$ and $6^{th}$ grades of elementary science in the 2009 revised curriculum were analyzed, and the types of questions distributed by grade. The percentage of questions by type was also different. Based on the results of this study, students' needs for learning can be grasped through the pre-questions analysis framework and reflected in the teaching-learning process, and student-centered learning contents and methods could be presented. It is expected to make a meaningful contribution to the analysis framework.

The purpose of this study is to verify the effects of team trust and cooperative behavior on the food-service employees' perceived service performance as well as the moderating effects of team competency and other department support in the relationship among the team trust, cooperative behavior, and service performance of food-service employees. We conducted a survey of 1,080 food-service employees working in 8 hotels and 4 food-service stores located in Seoul, Gyeonggi, Song-do, Gyeongju, and Busan, and 841 food-service employees were employed for statistical analysis except unreliable responses. As a result of a SEM (structural equation modeling) analysis to confirm hypotheses, it was found that team trust (leader trust and co-worker trust) had a positive effect on the cooperative behavior. In addition, the cooperative behavior had a positive influence on the food-service employees' perceived service performance. Also found was the moderating effect of other department support in the relationship between the cooperative behavior and food-service employees' perceived service performance. Based on the research findings, we discussed its academic and practical implications, and suggestions on the future research.
