In this article, we propose a typology of industry convergences which encourages to invent new types of products and services through combining technologies across industries and identifying success factors of convergence industries which were resulted by industry convergences. In detail, the proposed typology of industry convergences is analyzed based on three viewpoints such as academic areas that provide the knowledge of convergence technologies, industry structures for the existing markets, and user experiences used for improving user friendliness. Such viewpoints can not only be considered as the sources for convergence industries but also be closely related with success factors of convergence industries. Based on the typology and the success factors of convergence industries, we suggest the implications about policies for the domestic industry convergence. It is expected that the results of this article can be widely applied to further activate industry convergences to overcome the recent global economic downturn.

With the contunuing trends towards an information based society, telecommunications services are becoming an integral part of social activities. So, emphasis on ISDN is growing rapidly and placed on supporting integrated services delivery of different levels to the end user. The end user’s perception of an integraged services delivery(in particular, ISDN services) should reflect three interrelated capabilities, ISDN access capabilities and ISDN network capabilities. For turning the ISDN concept of above capabilities into reality, we have implemented the experimental system on user-network interfaces, which are three kinds of implementations in user access arrangements, namely basic access, intermediate rate multiplexed access and primary rate multiplexed access. Through these implementations, NTE(Network Terminating Equipment) is used for single basic access [2B+D], IMUX (Intermediate rate Multiplexer) for 4 basic accesses [4X(2B+D)] and PMUX(Primary rate Multiplexer) for [10/12 X (2B+D)]. This paper describes the outlines of system features on user access equipments, system architectures of testbed and experiment result of each access arrangements.

In this study, an empirical research based on survey has been performed to study the influence of user expectation to user satisfaction of commercial and open source DBMSs. According to the survey results, word-of-mouth and past experiences influence significantly to user expectation, and price influences to user expectation only for commercial DBMS users. The results show that the expectancy disconfirmation influences significantly to user satisfaction. Expectation and satisfaction levels of commercial DBMS users are higher significantly than those of open source DBMS users. However, expectancy disconfirmation of open source DBMS users is higher than that of commercial DBMS users.

With the recent expansion of the commerce ecosystem, a large number of user evaluations have been produced. Accordingly, attempts to create business insights using user evaluation data have been actively made. However, since user evaluation can change after the user experiences the product, it is difficult to say that the analysis based only on reviews immediately after purchase fully reflects the user's evaluation of the product. Moreover, studies conducted so far on user evaluation have overlooked the fact that the length of time a user has used a product can affect the user's product evaluation. Therefore, in this study, we build a model that predicts the direction of change in the user's rating after use from the user's rating and reviews immediately after purchase. In particular, the proposed model reflects the product's period of use in predicting the change direction of the star rating. However, since the posterior information on the duration of product use cannot be used as input in the inference process, we propose a structure that utilizes information about the product's period of use using an auxiliary classifier. As a result of an experiment using 599,889 user evaluation data collected from the shopping platform 'N' company, we confirmed that the proposed model performed better than the existing model in terms of accuracy.

최근 한국에서 만화/애니메이션 시장 성장과 향유계층의 증대로 더 많은 사람들이 문화콘텐츠의 수동적 수용에서 나아가 적극적으로 재생산하는 단계에 이르고 있다. 유저들의 손에 의해 만들어지는 파생 콘텐츠, 2차창작은 오리지널 콘텐츠의 외연을 더욱 확대시키고 이러한 요소가 원작에 재흡수되어 콘텐츠 시장을 더욱 풍성하게 만드는 선순환 구조를 이룬다. 이러한 관점에서 특성화된 지역축제로서의 만화축제는 만화/애니메이션을 적극적으로 수용하고 있는 사람들을 통해 더욱 활성화될 수 있는 가능성이 존재하고 있으나, 다른 지역문화축제에서와 마찬가지로 만화축제에서도 적극적 참여자로 분류되는 이들의 사용자경험이 축제의 의사결정 과정에서 적극적으로 반영되고 있지 못하다는 한계가 존재하고 있다. 코스프레는 만화/애니메이션을 재생산하여 즐기는 방식의 하나이다. 만화, 애니메이션, 혹은 영화 속의 캐릭터를 옷과, 메이크업, 머리모양, 소품 등을 이용해 표현하고 이러한 모습을 타인에게 보여줌으로서 자신은 물론 관객에게도 즐거움을 주는 놀이 문화이다. 이러한 코스프레 참가자는 이제 각종 만화 축제와 게임쇼를 돋보이게 하는 뺄 수 없는 요소가 되어가고 있다. 부천 국제 만화축제 역시 코스프레를 축제 구성 콘텐츠로서 채용하고 있으며 이를 통한 행사의 홍보 역시 전개해 나가고 있다. 하지만 부천 국제 만화축제에서의 코스프레는 다른 만화 축제와 구분되는 여러가지 특징을 지니고 있으며 이는 코스플레이어들에게 부천국제만화축제를 다른 축제와는 이질적인 존재로 받아들이는 요인이 되고 있다. 본 연구에서는 2013년과 2014년 부천국제만화축제에 참가한 코스어들의 경험을 문화기술지적 방법으로 인터뷰와 참여관찰을 통해 조사했다. 조사 결과, 코스어들은 만화축제 내부에서의 참여 범위가 제한되었으며, 축제 활동을 통해 비교적 부정적인 경험을 구축하고 있었다. 이러한 문제에 대한 대안으로 본 연구는 객체화되고 있는 적극적 참여자들이 가진 사용자경험을 축제에 보다 지속적으로 반영할 방법론 구축의 필요성을 제기하고자 한다.

In recent times, education facilities for children have focused on the importance of the "living environment" of children. This is because children have a more sensitive response than adults in their lives. All of the field activities, body movement, and play they go through in their living environment exhibit a great educational effect while promoting their emotional, physical, and mental development; therefore, these are the main priority factors in planning an education facility for children. A space may be deemed to be created by the relationship between objects and the people who perceive them. Also, space cognition may be defined to be made of the perception of a space, integration with experience, and restructuring. Physical factors and visual factors, which are the basic factors composing a space, either play their roles as independent variables in a space or form a relationship through a combination between the factors; thereby, diverse types of space experiences may be created. Space experience may be realized through the "movements" of a user, and a user selectively experiences a space through his/her voluntary movements, while experiencing the space against their will through flexible movements. In particular, space experience through movements has an effect on children in terms of making them feel like having daily exploration, and it also has a positive effect on education. A movement space in which "movements" appear most strongly in an education facility for children connects various nearby spaces, and it also portrays a transfer role. Furthermore, in this space, a variety of space changes can be found; thereby, children are able to have diverse selective space experiences.

The growth of Internet usage even accelerated by the spread of high-speed Internet access network such as ADSI is affecting our socioeconomic activities and culture in a great way. Korea is recently reported to be the number one high-speed Internet network subscription per 100 people in the world. In a way to reflect this situation, we collect a moderate size of sample proportional to the population of each region across country and investigate what factors might explain the level of user's dissatisfaction with respect to Internet service they have been receiving. The results indicate that the set of gender, age, Internet usage, service kinds, incoming e-mails, and e-shopping is significantly influencing user's dissatisfaction, in that dissatisfaction is measured in 11 perspectives. In particular, user's age, gender, and e-shopping experiences are considered to be mostly explainable.
