Most of cultural area which people enjoy and consume is kitsch culture, though the culture is barely acknowledged. In this multimedia era, people create, publish and enjoy contents of 'webtoon(web+cartoon)', which is relatively faster and more convenient to enjoy comparing to published cartoon. Contrarily to its physical growth, the webtoon shows difficulty in advancing with other genres, is full of irritative factors and contents, and has tough time to become more sophisticated one. This study derived characteristics of kitsch in webtoon, suggested the way of webtoon as an art by analyzing conditions and usage motivation of webtoon. The conditions of kitsch are uniformity of mass consumption, popular vein, catharsis, vicarious satisfaction, immediate feedback-requiring image flood, and reproduction of techniques. The usage motivations of webtoon are studied as pursuit of information, entertainment, relaxation, socialization, convenience, and effectiveness. Usage motivation factors in webtoon and kitsch culture are almost identical. Contrary to its past of being underestimated and vulgarly considered, kitsch is acknowledged as an 'kitsch art'. By studying the process of becoming an art, the study has its purpose to suggest the experimental and developing way to make webtoon be acknowledged as 'webtoon art'.

게임에서는 장애물이 가로 막고 있을 때 길 찾기 알고리즘이 요구된다. Path Finding Method 는 길과 장애물을 고려하여 목적지까지의 경로를 찾는 방법을 말한다. A^* 알고리즘은 이런 복잡한 미로 찾기에 최적화된 Path Finding 알고리즘이다. 하지만, 모바일 같은 저비용 기기에서 A^* 알고리즘을 사용하기엔 단순한 지형에서도 연산 부하가 발생할 수 있다. 본 논문에서는 가상의 공간에서 Grid를 구축하여, 통행이 가능한 곳과 불가능한 곳을 나누어 최종 지점에 도달할 수 있도록 하는 방식을 제안한다. 본 논문에서 제시한 Path Finding Method 는 최종 지점이 막다른 길인 경우 가장 가까운 이동 가능한 경로로 길을 안내하도록 설계하여 예외 상황에 대처했다. 대표적인 길 찾기 알고리즘인 Dijkstra 알고리즘은 최소 비용을 고려해서 최단으로 가는 거리를 비교하여 길을 나타낼 수 있다. 하지만, Dijkstra 알고리즘 경우 비용이 양수가 아닌 음수의 경우 무한 루프에 빠지는 등 결과 값이 제대로 나오지 않을 수 있다. 본 논문에서 제안한 Path Finding Method 는 최소 비용을 노드별로 비교하는 방식이 아닌 초기 비용을 알 수 없는 분야에 쉽게 사용할 수 있다. 본 논문에서는 제안한 Path Finding Method 를 적용하여 Web 게임을 제작하는 것에 성공하였다. 향후, Path Finding Method 결과에 위치 정렬 알고리즘을 적용하여, 중복된 지역을 가는 확률을 최소화하면서 정리된 Path 가 돌출되도록 연구할 예정이다. 본 논문의 Path Finding Method 은 게임 개발 분야에 적극 기여되길 바란다.

As web technology and educational environments are in rapid progress, web-based cooperative learning systems have gained a lot of interests. Recently some studies have attempted to combine a learning system and simple games that enable learners to actively participate and have high interests in learning. These studies are based on TGT model, a cooperative learning model using games, and mostly remain system design levels. A few implemented systems have many problems because they focus only on pure TGT model. To solve these problems, this paper builds a extended TGT model and a new web-based cooperative learning system using this new model. The extended part contains ideas such as expert learning from Jigsaw II model, improvement scores from STAD model and making game problems by learners. A system using pure TGT model and a suggested system are implemented and used by two classes of middle school students to evaluate our system. The experimental results show that our system outperforms the other system.

This study aims to examine the realistic self-esteem of adolescents and perception of adolescents toward avatar in an attempt to understand basic aspects of their distinctive lifestyle fundamentally relative to the cyber culture on the web, given that the adolescent which is significant in forming self-esteem period plays an important role in the psychological aspect of adolescents. As for method of research, this study analyzed the self-esteem of users, their preference for avatar, and the perception toward avatar, in order to understand their psychological and social maturity. The result of study indicated that the increased self-esteem in reality among the adolescents led to the increased preference for avatar relative to the cyber culture on the web, which in turn increased the recognition of others' avatars. Those findings suggest that adolescents tend to assign self-esteem to avatar as great as themselves. Thus, it may be important to help adolescents form their self identity from the perspective psychological maturity, so that a sound and healthy web culture can be formed depending on the formation and level of self-esteem among adolescents.

As Internet usage widely grows, online content services such as newspaper, magazine, music, game and movie are provided with a fee-based subscription. Many content services providers consider charging a usage fee into its service provisions as one of the Internet business models for increasing revenue. There are customer resistances to adopting the fee-based service provision on the Web. Previous research in information systems (IS)has focused on the analysis of adoption of information technology or systems in the individual ororganization level. No principle research has been carried out on the user adoption behavior of online content services provisions. As users actively access content services on the Web, it needs to explore user adoption behavior in different settings. Many IS researcher have employedquantitative approaches, even though they deal with the process of user behavior regarding the information technology or system. In this study, we attempt to discover how customers adopt the fee-based provision of online content services by employing grounded theory, one of the principal qualitative research methods.

Past clustering researches are focused on extraction of keyword for word similarity grouping. However, too many candidates to compare and compute bring high complexity, low speed and low accuracy. To overcome these weaknesses, this paper proposed a topical web document clustering model using not only keyword but also named entities such as person name, organization, location, and so on. By several experiments, we prove effects of our model compared with traditional model based on only keyword and analyze how different effects show according to characteristics of document collection.

Recent days intellectual systems using reinforcement learning are being researched at various fields of game and web searching applications. A good training models are called to be fitted with trainning data and also classified with new records accurately. A overfitted model with training data may possibly bring the unfavored fallacy of hasty generalization. But it would be unavoidable in actual world. The entropy and mutation model are suggested to reduce the overfitting problems on this paper. It explains variation of entropy and artificial development of entropy in datamining, which can tell development of mutation to survive in nature world. Periodical generation of maximum entropy are introduced in this paper to reduce overfitting. Maximum entropy model can be considered as a periodical generalization in intensified process of intellectual web searching.
