The objective of this study is to investigate what factors influence a major role in building trust on Internet shopping mall and to examine whether these factors on trust have differences between Korean and Chinese users. Based on relevant literature review, this study posits six factors of transaction security, perceived reputation, Perceived size, interactivity, propensity of trust, and familiarity as key determinants of trust in internet shopping mall. Analysis of 470 responses(Korean: 320 users, Chinese: 150 users) of survey questionnaire indicates the following; First, in terms of the relationship between influencing factors and the trust, five factors of transaction security, perceived reputation, perceived size, interactivity, and propensity to trust have a significant positive effects on the trust. Second, the differences between Korean and Chinese users are transaction security, perceived size, and familiarity. In conclusions, we suggested the factors to create user trust in internet shopping mall. Also we suggested differences in the determinant factors between Korean and Chinese users, and discussed some policies to build the trust in each user types.

A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.

The objective of this study is to investigate factors influencing trust on internet shopping mall and to examine whether these factors on trust have differences between Korean and Chinese users. Based on the literature reviews, this study employs six factors in two groups of influencing factors, web-site characteristics and individual characteristics as key determinants of trust in internet shopping mall. Analysis of 470 responses (Korean: 320 users, Chinese: 150 users) of survey questionnaire indicates the following: In terms of the relationship between web-site characteristics factors and the trust, the results showed clear differences between Korean and Chinese samples. For the Korean samples, transaction security and interactivity were the only significant influencing factors. For the Chinese samples, perceived reputation and perceived size were the only significant factors. In terms of individual characteristics factors, the influencing factors were found identical for the samples. Both propensity to trust and familiarity were significant factors in both Korean and Chinese samples. Based on the findings, managerial implications are discussed in building user trust in internet shopping mall in Korean and Chinese market.

우리가 현재 구사하고 있는 단어의 70% 이상이 한자로 되어 있는 만큼 무엇보다도 정확한 의미 전달을 위해 한자 교육의 필요성은 날로 높아져 가고 있다. 최근에는 단순히 한자의 독음만이 아닌 한자를 정확히 쓰는 것에 대한 관심이 높아지고 있으며, 이에 따른 서적들과 인터넷을 이용한 콘텐츠들이 개발되어지고 있다. 그러나 현재 웹을 이용하여 개발되어진 한자 교육을 위한 콘텐츠들은 대부분 한자의 독음과 해석만을 중심으로 구성되어 있다. 또한 한자 쓰기에 대해서는 한자를 출력해서 연습할 수 있도록 하는 학습지형태로 제공하고 있다. 따라서 한자 쓰기에 대한 비중이 많이 미약하다. 이에 본 논문에서는 웹 기반의 한자 쓰기 시스템을 설계하고자 한다. 이를 통해 사용자는 마우스를 이용하여 직접 한자를 써 보고, 그에 따른 학습 진도를 관리할 수 있다. 또한 이 시스템은 웹을 이용하여 인터넷이 연결된 어느 곳에서든지 사용할 수 있는 시스템을 제공하는데 그 목적이 있다.

본 연구에서는 모바일 인터넷 서비스를 중심으로 사용자들의 인구통계적 특성에 따라 선호하는 콘텐츠 유형이 달라지는가를 규명하고자 하였다. 또한, 이러한 모바일 인터넷 서비스 사용자의 특성과 선호하는 콘텐츠 유형간의 관련성이 국가에 따라 차이가 존재하는가를 파악하고자 하였다. 이러한 연구목적을 달성하기 위하여, 본 연구에서는 대가설 2개와 세부가설 8개의 연구가설을 설정하였으며 한국과 중국의 휴대폰 사용자들을 대상으로 설문지를 의뢰하여 최종적으로 505부의 표본을 대상으로 통계분석을 실시하였다. 분석 결과, 본 연구에서 설정한 모바일 인터넷 서비스사용자의 특성에 따라 선호하는 콘텐츠 유형은 달라질 것이다라는 연구가설과 모바일 인터넷 서비스 사용자의 특성과 선호하는 콘텐츠 유형간의 관련성은 국가에 따라 달라질 것이다라는 연구가설이 부분적으로 채택되고 있음을 확인할 수 있었다.

More and more researchers and practitioners in the field of e-commerce are paying attentions to the retention of online customers. However, only a few researches can be addressed in the context of internet shopping mall repurchase intention. This study aims at investigating and delineating the important characteristic factors which affect consumers' repurchase intentions by conducting an empirical analysis. In order to fulfill this purpose effectively, a comprehensive review of previous studies regarding information system success model was performed in order to render a stronger theoretical foundation for our study. Finally, based on the DeLone and McLean (2003) IS success model, information quality, system quality, service quality, customer satisfaction and repurchase intention were employed as five constructs in the research model and hypotheses on mutual relationships between these constructs were established accordingly. Structural equation modeling was employed to analyze the data collected from 204 internet shopping mall consumers in China. Our theoretical model exhibited a good fit with the observed data. The empirical results showed particularly strong support for the effects of information quality, service quality and user satisfaction. The findings of this research contributed to the extension of repurchase intention study in the context of Internet shopping malls. Our research also offered implications for practitioners in regards to devising internet shopping malls so as to increase consumers' repurchase intention to use these services.

This paper focuses on the simplified receiver design for multi-user circular block oversampled filter bank (CB-OSFB) uplink systems. Through application of discrete Fourier transform (DFT), the special banded structure and circular properties of the modulation matrix in the frequency domain of each user are derived. By exploiting the newly derived properties, a simplified zero-forcing (ZF) receiver is proposed for multi-user CB-OSFB uplink systems in the multipath channels. In the proposed receiver, the matrix inversion operation of the large dimension multi-user equivalent channel matrix is transformed into DFTs and smaller size matrix inversion operations. Simulation is given to show that the proposed ZF receiver can dramatically reduce the computational complexity while with almost the same symbol error rate as that of the traditional ZF receiver.

우리가 현재 사용하고 있는 단어의 70% 이상이 한자로 구성되어 있는 만큼 정확한 의미 전달을 위해 한자 교육의 필요성이 높아지고 있다. 또한 최근에는 단순히 한자의 독음과 뜻 뿐 만이 아니라 정확한 획순에 의해 올바로 한자를 쓰는 것에 대한 관심이 높아지고 있다. 이에 사용자의 학습 편의성을 제공하기 위한 서적들과 인터넷을 이용한 콘텐츠들이 개발되어지고 있다. 그러나 인터넷을 이용한 대부분의 콘텐츠들은 단순한 독음과 뜻만을 제시하고 학습하는 곳에 초점이 맞춰져 있다. 또한 서적들은 획순에 의한 한자 쓰기 학습을 적용하고 있으나 획일적인 반복만을 강조함으로써 학습효과가 높지 못하다. 따라서 본 논문에서는 웹을 통하여 인터넷상의 사용자가 언제 어디서나 자기 주도적 학습을 가능토록 하며, 한자의 독음 및 뜻과 함께 필순에 의한 쓰기 기능을 제공하는 콘텐츠를 구현하였다. 이를 통하여 사용자 중심의 자기 주도적 학습에 의한 학습 상황 관리 및 한자 학습에 있어서 정확한 읽기와 쓰기를 이해함으로써 학습 효과의 효율성을 높일 수 있다.

China has the largest number of the user of web 2.0 such as messengers and blogs, as of 2008 year. Chinese Internet digital market will grow from $85 billion in 2007 to $264 billion in 2015. The importance of Chinese Internet business is increasing, because of its size and growth potential. This research is focused on following two questions. First, what are the major characteristics of social networking services in China? In order to find out the answer about this question, the case study on Tencent QQ and Sina Poco, the most representative social networking services company in China, was done. And the reason of the use of social networking services, their contents, and the attitude toward the paid service were identified. Second, what are the major factors influencing the use of social networking services in China. User participation, network effect, usefulness, and system quality were inferred as the factors influencing the use. These factors were based on motivation theory, technology acceptance model, and the related research papers. This research model was proved by data analysis using Partial Least Square. As results, the use of social networking services was influenced by usefulness, network effect, user participation, and system quality. But social influence was not significant of the use of social networking services.
