The Korean online gaming industry has seen rapid growth since the boom of information technology (IT) related industries, especially Internet and PC-bang or local area network (LAN) use, throughout the country. Online games are real-time games in which two or more players meet, compete, and cooperate in the same game space using the same communication network. Even though the growth rates of IT-related industries have recently slowed, the growth of the online gaming industry has increased, and Korean firms are expanding their businesses to countries all over the world. However, the online gaming industry is becoming an oligopoly, in which 4-5 leading companies occupy most online gaming markets. This situation presents a disadvantage to the Korean online gaming industry, since online players usually seek a diversity of online gaming contents and high quality online game services. Therefore, small- and medium-sized game developers must survive in this market by upgrading the quality of their online gaming services in an effort to provide differentiated goods and services in monopolistic competition markets. However, most venture companies in the online game industry, whether new or previously existing, are not able to obtain adequate financing. The objective of this paper is to examine the management environment for medium- and small-sized game developers in the Korean online gaming industry. By introducing the case of Grigon Entertainment, we try to identify the source of difficulty obtaining external financing for Korean venture firms in the online gaming industry.

The task network which is formed of different individuals can be recognized as a social network. Therefore, the way to communicate with people inside or outside the network has considerable influence on their outcome. Moreover, the position on which a member stands in a network shows the different effects of the information systems supporting communication with others. In this paper, it is to be studied how personal CMC (computer-mediated communication) tools affect the mission that those who work for a network perform through diverse task networks. Especially, we focused on synchronicity of CMC. On this score, the perspective of Media Synchronicity Theory was taken that had been suggested by criticizing Media Richness Theory. It is the objective, from this perspective, to find which characteristics of networks make the value of IT supporting synchronicity high. In the research trends of social networks, there have been two traditional perspectives to explain the effect of network: embeddedness and diversity ones. These differ from the aspect which type of social network can provide much more economic benefits. As similar studies have been reported by various researchers, these are also divided into the bonding and bridging views which are based on internal and external tie, respectively, Size, density, and centrality were measured as the characteristics of personal task networks. Size means the level of relationship between members. It is the total number of other colleagues who work with a specific member for a certain project. It means, the larger the size of task network, the more the number of coworkers who interact each other through the job. Density is the ratio of the number of relationships arranged actually to the total number of available ones. In an ego-centered network, it is defined as the ratio of the number of relationship made really to the total number of possible ones between members who are actually involved each other. The higher the level of density, the larger the number of projects on which the members collaborate. Centrality means that his/her position is on the exact center of whole network. There are several methods to measure it. In this research, betweenness centrality was adopted among them. It is measured by the position on which one member stands between others in a network. The determinant to raise its level is the shortest geodesic that represents the shortest distance between members. Centrality also indicates the level of role as a broker among others. To verify the hypotheses, we interviewed and surveyed a group of employees of a nationwide financial organization in which a groupware system is used. They were questioned about two CMC applications: MSN with a higher level of synchronicity and email with a lower one. As a result, the larger the size of his/her own task network, the smaller its density and the higher the level of his/her centrality, the higher the level of the effect using the task network with CMC tools. Above all, this positive effect is verified to be much more produced while using CMC applications with higher-level synchronicity. Among the a variety of situations under which the use of CMC gives more benefits, this research is considered as one of rare cases regarding the characteristics of task network as moderators by focusing ITs for the operation of his/her own task network. It is another contribution of this research to prove empirically that the values of information system depend on the social, or comparative, characteristic of time. Though the same amount of time is shared, the social characteristics of users change its value. In addition, it is significant to examine empirically that the ITs with higher-level synchronicity have the positive effect on productivity. Many businesses are worried about the negative effect of synchronous ITs, for their employees are likely to use them for personal social activities. However. this research can help to dismiss the concern against CMC tools.

지능형 교통체계(Intelligent Transport Systems: 이하 ITS)의 제반서비스는 사용자가 요구하는 다양한 형태의 동적교통정보의 제공가능성이 전제되어야 한다. 이는 많은 데이터 및 정보들이 수집, 가공단계를 거쳐 최종 정보이용자에게 효율적으로 전달되어짐을 의미하며 이를 위해 GIS기반의 공간데이터베이스를 사용하게 된다. 현재 국내외에서 교통관련시스템에서 사용되는 공간데이터베이스는 시스템의 목적에 따라 상이한 설계와 내용을 가지고 있다. 이는 시스템간에 공간상의 위치정보를 공유함에 있어서 시스템에 맞는 적절한 변환과정을 거쳐야만 한다. 특히 실시간으로 정보의 공유가 필요한 경우는 더 큰 문제를 노정하고 있다. 본 연구에서는 ITS서비스에서 사용되는 공간위치정보-동적위치정보, 정적위치정보-를 시스템간에 실시간으로 공유하기 위해 ITS Map Datum (기본이 되는 지형데이터)과 위치참조기법을 개발하고 실제 적용을 위한 한가지의 프로파일을 제안하였다. 또한 제안된 프로파일과 지리정보 소프트웨어를 이용하여 서로 다른 공간데이터베이스상에서도 교통 정보가 제공되어지고 더 나아가 공유되어질 수 있는 가능성을 평가하였다.
