CSR(Corporate Social Responsibility), as company's survival strategy, recently has an increasing importance in the world and becomes a global trend as a requisite of improving national competitiveness. That is because advanced countries hurry to standardize the CSR so that it can give systematic complementary methods to the right and reverse function due to many emerging multinational corporations and trade increase between nations. This study is the basic study to expand the CSR awareness of online game development company resulting from this problem. Yet the CSR-related discussions in Korea is still in its infancy even in the general companies. But online game industry has overseas export possibility, especially high profit in another country. The complete preparation is the key to the rise and fall of online game, furthermore related companies.

Domestic On-line game market becomes keen competition gradually. So, work which advance into the new market is very important work which it takes future of Korean on-line industry. Recently, Chinese on-line game population is soaring by development of on-line infrastructure and elevation of the Intern et speed. Also, growth of China economy improved purchasing power. So, international market is desiring China market. Because China on-line game market has High potential energy, no one is opposed to truth that China market's advance gives opportunity of great success. So, this China market's charm advanced many domestic companies to China market. Also, many domestic companies are preparing for China advance. However, we did not understand perfectly circumstance of China market, and advanced impatiently without thorough preparation. So, occasion that the latest domestic companies fail greatly is increasing. Finally, we can know that China market's advance is difficulty. Therefore, we must analyze circumstance of China game market systematically, and do thoroughpreparation and preparatory audit that is enough with wider visual field. So, we must think investment about the future more than that think in a short time profit.

The purpose of this study is to explore what causes medical college students to play games they will play and use them as academic foundation material. And lay a complex foundation for game addicts. To achieve this objective, an approach was taken as a method of exploratory case study. The participants in the study were recruited by their consent at the R meeting of the College of Medicine. Data collection was collected through a one-on-one interview with FGI. The data analysis was read repeatedly and classified into semantic units to derive the essential meaning. The study produced two essential topics and seven revealed topics. It is 'my job to play games' and 'know the importance of discrimination.'According to the analysis, the game behavior played by medical students was able to quit due to the self-efficacy experienced during the course of growth. When one's expectations were met and self-strengthened, one could see that self-control was possible through self-efficacy. It suggested that measures for sound game culture and complex strategy should be explored and measures to improve self-efficacy should be explored.

최근 온라인 경매나 오픈 마켓 같은 온라인 전자상거래가 활발히 이루어지고 있다. 더불어 사용자가 PDA와 같은 단말기를 휴대하고 이동하는 동안 전자상거래가 이루어질 가능성이 높아지고 있다. 이러한 상황에서 온라인 전자상거래의 구매자와 판매자를 대신해서 협상을 수행하고 매매를 성사시키는 에이전트에 대한 연구가 시도되고 있다. 이를 확장하여 지능형 에이전트를 휴대형단말기에 적용함으로써, 모바일 환경에서 구매자와 판매자간의 전자상거래를 대행하는 협상 에이전트의 필요성이 부각되고 있다. 본 연구에서는 모바일 전자상거래환경에서 에이전트가 협상에 대한 합리적인 판단할 수 있도록 게임이론을 사용하여 모델화 하였고, 휴대형단말기가 블루투스를 통해 인근에 있는 상점을 탐색 및 블루투스 네트워크를 구성하도록 하였다. 또한, 사용자가 협상 항목을 단계적으로 변경할 수 있는 전략을 사용할 수 있게 하였으며, 이를 평가함수를 사용하여 협상해서 최종 거래 결정은 자동 또는 수동으로 성사되게 하였다. 기존 협상 모델은 가격과 배송 방법 같은 협상 항목에 대해 가중치만을 변경하여 만족도를 판단함으로써, 실질적인 항목의 변화는 없고 초기에 설정된 협상 항목이 변경되지 않는 문제점이 있었다. 본 연구에서는 다단계 전략을 사용하여 단계마다 사용자의 요구 사항을 변경시킬 수 있기 때문에, 초기에 설정한 협상 항목의 값이 단계별로 변경될 수 있어 사용자의 의도가 협상에 실질적으로 반영되는 효과가 있다. 더불어 오프라인 전자상거래에서는 구매자가 직접 상점을 방문하여 상품을 검색하고 협상하였다. 그러나, 본 연구에서는 이동중인 사용자의 인근에 위치한 상점 에이전트로부터 상품 정보를 받는다. 그 후에 에이전트가 구매 협상을 하기 때문에 사용자가 이동 중에 상가에 직접 들어가지 않고도 상품을 검색 및 협상 할 수 있는 장점이 있다. 본 논문에서는 제안한 모바일 쇼핑 에이전트를 구현하고, 협상 과정과 결과를 비교하여 모델의 타당성과 성능을 평가한다.

This study evaluated the priority of port development in Korea using game theory. First of all, the study selected residents, users and local governments as the subject of port development and measured total evaluation value with the AHP method. In addition, considering complaint level depending on comprehensive evaluation results and selected alternatives in case of affiliation between evaluating subjects, the study proposed a minimizing evaluation method. Also, compensation depending on the selected alternatives was quantified, with compensation strategy being presented. The findings of this study revealed that Busan port should be taken into consideration first for the port development in Korea, as an environmentally friendly port.

The purpose of this study was to explore relationships between preschooler's aggression and social skills, maternal management strategies of peer relations and parenting behaviors and preschoolers' internet-game addictive inclination. Participants included seventy-seven (77) 5 to 6-year-old preschoolers (44 boys, 33 girls) and their mothers. The Aggressive Behavior Scale (Lee & Choi, 2001), the Social Skill Rating Scale (Suh, 2004), the Maternal Parenting Behaviors Scale (Rhu & Lee, 2007) and the Parental Involvement Checklist (Park, 2001) were used in this study. The Internet Game Addiction Scale (Korea Agency for Digital Opportunity and Promotion, 2006) was used to identify higher and lower addictive level of internet-game inclination. Collected data were analyzed by descriptive statistics and t-test. Major findings revealed that preschooler's social skills, maternal management strategies of peer relations and parenting behaviors showed a predictable correlation to preschooler's internet-game addictive inclination.

The purpose of this study is to identify key factors of Co-opetition through examining the environmental and structural changes in the ports industry and suggest a few Co-opetition strategies for enhancing our ports capabilities in the long-term. In recent years, the trend toward market liberalization and globalization in ports industry has made rapid progress and it made the competition fiercer. To survive in this rapid changes, the ports have traditionally pursed a competitive strategy. However, an alternative strategy replacing the traditional strategy was introduced: namely, 'Co-opetition' a buzzword combining competition and co operation. Policy proposals this study suggests are the construction of a database regarding costs and benefits of ports for more effective analysis and improving the competitive power of a shipping company operating national flag carriers for achieving the purpose of Co-opetition and adoption of selection and concentration strategy for increasing the possibility of Co-opetition success.

This paper proposed the strategy learning method by means of the fusion of Back-Propagation neural network and Q learning algorithm for two-person, deterministic janggi board game. The learning process is accomplished simply through the playing each other. The system consists of two parts of move generator and search kernel. The one consists of move generator generating the moves on the board, the other consists of back-propagation and Q learning plus $\alpha$$\beta$ search algorithm in an attempt to learn the evaluation function. while temporal difference learns the discrepancy between the adjacent rewards, Q learning acquires the optimal policies even when there is no prior knowledge of effects of its moves on the environment through the learning of the evaluation function for the augmented rewards. Depended on the evaluation function through lots of games through the learning procedure it proved that the percentage won is linearly proportional to the portion of learning in general.

The purpose of this study is to analyse the cases of the posed problems while the mathematically gifted students are playing the NIM game. The findings of a qualitative case study have led to the conclusions as follows. Most of all mathematically gifted students in the elementary school are not intend to suggest the solutions of the posed problem unless the teacher or the 'problem is requested. But a higher level of promising children were changing each data components of a problem in a consistent way and restructuring the problems while controlling their cognitive process. This is compared to that a relatively lower level of promising children tends to modify one or two data components instantly without trying to look at the whole structure. And we gave 2 suggestions to teach the mathematically gifted students in the problem posing.
