The last few years have been a boom time for the online gaming industry. Internet-based online games have made an increasingly popular form of entertainment. The gaming industry estimates that online gaming players reach over 26 million in 2002. The rapid development of online game-contents and related information technology shall increase the size of industry and have a profound impact on many ways of our living and sociaty. This paper develops the exploratory LISREL model for identifying the factors attecting the players' loyalty for some specific brand of online games. The concept of flow, word of mouth, feedback, challenge, social norms, and online community activities, etc, are all introduced into the model, as the independent variables affecting the loyalty directly and indirectly. Based on data collected from online questionnaire survey, the validity of the model has been tested and interesting conclusions have been developed concerning the relationships between the loyalty, flow, word of mouth and other set of independent vareables. It is hoped that this result might provide the useful guidelines for developing the successful online game contents.

Online design education, started with the establishment of cyber universities in Korea in 2001, has been operated with the development of online classes for various subjects until present and is predicted to be expanded both quantitatively and qualitatively as the concept of remote education is gradually generalized along with the growth of cyber universities and the development of digital technologies. However, regardless of such quantitative growth and possibility of development, the current online design classes are operating curriculum that is not much different from that of design department at the existing offline universities, while the concepts and roles of design and designer are changing according to the stream of digital times. Moreover, although complex elements are required to be considered since online design education is influenced by digital technological trend as being a form in which digital technology, contents, and design are all combined and advantages and features of online are required to be reflected to the maximum, the reality is different from what has been expected due to many circumstances. Online design education needs to be changed in accordance with the stream of digital times and new online design curriculum suitable for the current of future digital times and online environment are required to be developed and prepared at this moment. Accordingly, this research aims to look into the concepts and roles of design and designer changing in accordance with the stream of digital times by researching the existing literatures as well as the advantages and features of online class and to analyze the current state of curriculum of digital design and related departments at cyber universities in Korea to suggest an improvement direction of curriculum of online design class suitable for the future digital times.

The tourism industry has attained remarkable growth, and the need for professional Tourism English education has increased. Universities of online education can offer an environment for education to both job applicants and laymen who are interested in Tourism English. Tourism English belongs to English for Specific Purposes, which reflects the needs of specific area. The aim of this study is to propose improvements in classes design for online Tourism English instruction. The results of a needs analysis conducted on 160 Korean online university students suggest that online Tourism English class should be different from a traditional classroom-based one in regards to aims, contents, and methods. Online Tourism English class should not only focus on English for specific purposes, but also include more generalized topics. This comes as a result of the diverse backgrounds of online students. The results suggest that extralinguistic elements, such as culture and etiquette differences among English-speaking countries, become more interesting when introduced using pictures, videos, animations, etc. Additionally, SMS or emails can be utilized to raise students' motivation for online Tourism English class.

Real-time multimedia streaming over the Internet is rapidly increasing with the popularity of user-created contents, Web 2.0 trends, and P2P (peer-to-peer) delivery support. While many homes today are broadband-enabled, the quality of experience (QoE) of a user is still limited due to frequent interruption of media playout. The vulnerability of TCP (transmission control protocol), the popular transport-layer protocol for streaming in practice, to the packet losses, retransmissions, and timeouts makes it hard to deliver a timely and persistent flow of packets for online multimedia contents. This paper presents TCP-real-time online multimedia environment (ROME), a novel transport-layer framework that allows the establishment and coordination of multiple many-to-one TCP connections. Between one client with multiple home addresses and multiple co-located or distributed servers, TCP-ROME increases the total throughput by aggregating the resources of multiple TCP connections. It also overcomes the bandwidth fluctuations of network bottlenecks by dynamically coordinating the streams of contents from multiple servers and by adapting the streaming rate of all connections to match the bandwidth requirement of the target video.

In this paper, we propose a transformation scheme used to analyze online gaming traffic properties and develop a traffic model. We analyze the packet size and the inter departure time distributions of a popular first-person shooter game (Left 4 Dead) and a massively multiplayer online role-playing game (World of Warcraft) in order to compare them to the existing scheme. Recent online gaming traffic is erratically distributed, so it is very difficult to analyze. Therefore, our research focuses on a transformation scheme to obtain new smooth patterns from a messy dataset. It extracts relatively heavy-weighted density data and then transforms them into a corresponding dataset domain to obtain a simplified graph. We compare the analytical model histogram, the chi-square statistic, and the quantile-quantile plot of the proposed scheme to an existing scheme. The results show that the proposed scheme demonstrates a good fit in all parts. The chi-square statistic of our scheme for the Left 4 Dead packet size distribution is less than one ninth of the existing one when dealing with erratic traffic.
