This paper is interested in analyzing the CSFs of 3 different kinds of on-line digital products. They are on-line digital products of (1) transaction, (2) relations, and (3) interests. This study first tried to define the on-line digital products based in the above three categories and then to find the factors that might effect the customer acceptability in each product groups. Independent variables used in this study are characters of products, characters of users, and system environments. This paper that on-line survey has been conducted for the study's specialty and the collected resource was analyzed by using the SPSS 10.0K statistics package. Using multiple regression, this study finds that major factors effecting the user acceptability of each group are different from one another. For example, system environment variables such as speediness, system performance effects the customer acceptability of digital products of Interest(game, avartar, etc). Much more then that of products of relations(information service, etc). Therefore empirical findings are suggested in the conclusion.

We study incentive structures of public developers and land owners in the process of public expropriations using a sequential game model. In the model, we show that there is an incentive for the public developer to give more compensation than just compensation that are defined by law. Also the model shows that there is an incentive for the land owners to revolt strategically against the public expropriation. Then an ideal authority delegation model is introduced to resolve the problems, where an independent appraiser determines the compensation for the expropriation. In the real world, improving the independence of appraisal process is critical to make the system closer to the ideal authority delegation model. So this paper concludes by making a few policy suggestions to improve the current appraisal system.

This study is to focuses on users' attitudes toward augmented reality games. Based on the Technology Acceptance Model (TAM) and Flow theory, continuous usage intention was set as a dependent variable, and immersion was set as a mediating variable. As independent variables, spatial presence, perceived interactivity, perceived pleasure, and sickness were set. Besides, this study strived to compare and analyze Korean and Chinese Data. The results of this study were as follows. First of all, Korean users significantly affected spatial presence, perceived pleasure, and immersion. Spatial presence and perceived pleasure had also mediated effects on continuous usage intention through immersion. However, perceived interactivity and sickness did not affect immersion and even no mediating effect to continuous usage intention. In the case of Chinese users, spatial presence, perceived interactivity, and perceived pleasure were grouped into one variable. This variable influenced immersion and also had mediated effect on continuous usage intention. However, sickness, like Korean users, did not affect the set path. This study had implications for analyzing user perspective using immersion, a significant variable in previous research. In addition, this study found similarities and characteristics through a comparative analysis between Korean and Chinese users indirectly.

In this paper, I had tried to analyze the relationship between the time assigned for computer usage and weakening eyesight. First of all, students classified by gender, school year, eyesight, and wearing glasses along demographic characters took part in a poll, and The questionnaire included questions about computer time, factors of weakening eyesight, and purpose of computer use. The finding in this analysis composed of a cross-tabulations between annual eyesight change and the factors to change their eyesight is that 63.6 % of 165 students participated in this survey weakened their eyesight within a year. To show a correlation between computer usage duration and worsening eyesight in this paper, regression analysis indicated weakened vision by computer usage duration per day and week instead of a year. In addition, according to the analysis between computer usage duration and weakened vision for the people who wear glasses or not trough Independent-Samples T test, weakened vision was shown in computer usage duration per day and week, but not shown in the duration by the year. Therefore, weakening vision was also worse for the people who didn't wear glasses than the others. This study indicated 24..5% of teenagers had poor eyesight by using their computer. According to the frequency analysis on purposes of computer usage, the biggest purpose accounting for 36.4% of the total was the computer usage as a game consol, and the computer as a learning tool was the next biggest purpose at 32.1%. This paper showed the correlation between computer usage time and a factor of weakened eyesight through an analysis of the factor. Therefore, schoolchildren's parents should be more interested in their computer usage.

One result of the trend towards globalization is an increased number of projects that focus on natural language processing. Automatic speech recognition (ASR) technologies, for example, hold great promise in facilitating global communications and collaborations. Unfortunately, to date, most research projects focus on single widely spoken languages. Therefore, the cost to adapt a particular ASR tool for use with other languages is often prohibitive. This work takes a more general approach. We propose an International Phoneticizing Engine (IPE) that interprets input files supplied in our Phonetic Language Identity (PLI) format to build a dictionary. IPE is language independent and rule based. It operates by decomposing the dictionary creation process into a set of well-defined steps. These steps reduce rule conflicts, allow for rule creation by people without linguistics training, and optimize run-time efficiency. Dictionaries created by the IPE can be used with the speech recognition system. IPE defines an easy-to-use systematic approach that can obtained 92.55% for the recognition rate of Korean speech and 89.93% for English.

Animation-related films and game industries have been expanding their markets rapidly responding to sharply increasing public demand. The production processes of major studios are getting more and more specialized and detailed. Therefore, they feel burden to manage and maintain as the HR and physical sizes are getting greater. So, independent studios which perform partial processes of the works are increasing over North America and Europe. Specialized studios build previous functions and related business models. They are expanding their areas. Therefore, this study targeted studios specialized in digital concept art in free production step. The characteristics of such studios were analyzed. To this end, first definitions of digital concept art concepts and functional & artistic features of entire production, and their application to business were deliberated through documents and online. Based on the results, the features of 'concept art service', 'self-brand business/ communication', and 'education service' were drawn. Second, based on it, targeting three con cept art studios such as Atomhawk (UK), FengZhu Design (Singapore), and Studio Gage (Korea), case research was done. Comparative analysis for the cases was conducted. It turned out that concept art studio s lead new market demand through active business strategies such as related contents development, marketing, etc. based on specialization. This research is significant to understand global trend of newly establishing specialized studios market and suggest reference data to improve prospective domestic specialized studios competitiveness.

This paper examines the composition and the content of media art which is an art education subject in a national curriculum of Australia; and discusses implications for Korean education curriculums. Media covered by Media Art subject in Australia are the multi types of general media including TV, movie, video, newspaper, radio, video game, the internet, and mobile media; and their contents. The purpose of ACARA's media art education curriculum is to improve creative use, knowledge, understanding, and technology of communication techniques for multiple purposes and the audiences. Through the Media Art subject, both the students and the community are able to participate in the actual communications with the rich culture surrounding them and to develop the knowledge and understanding of the 5 core concepts of language, technology, system, audience and re-creation while testing the culture. The implication of this study is as the following. ACARA's media art education curriculum has been developed as an independent educational program and has a special significance within Australian education curriculums. Although ACARA's media art education curriculum is formed as an independent subject, it is suggested within the curriculum to instruct in close connection with other subjects upon execution. Its organization and elaborateness in curriculum composition are very effective in terms of the teacher's teaching-learning design and as well as the evaluation. This seems to show a good model of leading media literacy curriculum. ACARA's media art education curriculum can be a great reference in introducing media literacy to Korean national education curriculums.

In recent years, mobile phone market is saturated in number of user term. Associated service providers struggle to provide various mobile services such as Internet, e-commerce, game, music etc. to increase ARPU (average revenue per user) instead. In this study we explore the factors which affect price tabs of mobile communication. As a conceptual foundation, this study introduces user factors-users' propensity to use mobile phones-as independent variables and mobile service functions as mediating variables. The research model was phones-as independent variables and mobile service functions as mediating variables. The research model was tested with data from Web-based survey of 1,500 mobile users and analyzed by structural equation modeling (SEM). Our results suggest that user factors impact the usage of mobile service functions and mobile service functions for information and convenience are positively related to price tabs of mobile communication. Implications for mobile service providers and policy makers are discussed.
