무선인터넷의 열풍이 21세기 들어 전세계 IT 시장을 뜨겁게 달구고 있다. '정보'와 '이동성'이 결합된 무선인터넷은 '유선에서 무선으로', '음성에서 데이터로' 급변하는 정보통신시장의 정점에 서서, 중국, 러시아와 서남아시아를 거쳐 유럽과 아프리카까지 연결하는 Korea발 $\ulcorner$CDMA 실크로드$\lrcorner$ 건설의 최첨병으로 성장하고 있다. 세계최초의 CDMA 상용국가 Korea가 세계최초 CDMA 2000 1X와 CDMA EVDO 등으로 그려낼 무선인터넷의 다양한 멀티미디어 서비스와 M-Commerce의 무한한 가능성이야말로 21세기의 $\ulcorner$Mobile Korea.를 이끌어 줄 미래를 위한 선택이다. 이를 위해 정보통신부는 2000.6월부터 무선인터넷 활성화 정책을 수립하여 이를 적극 추진 중에 있으며, 이에 따라 국내의 무선인터넷 시장도 1조원을 돌파하는 등 본격적인 활성화를 목전에 두고 있다.

O2O(Online-to-offline) service is the new commerce system form that mixed information search and payment of products and services from online and receipt of goods from offline. O2O commerce combine advantage of existing electronic commerce and redeem the critical point of each commerce circulation method, but earnings model is still lacking compared to development speed of O2O technology. Therefore this study drew common factor applied to O2O service to search success factor of O2O commerce on the point of view as a customer Centered by existing B2C electronic commerce, Mobile commerce, and service quality model of offline commerce included O2O commerce method. Further we suggest O2O success factor model combined new O2O success factor additionally reflecting qualitative research result based on drew O2O success service Quality factor.

The present research developed and empirically examined a theoretical model called a Mobile Channel Extension Model for consumer behavior toward mobile commerce. We proposed three antecedents: compatibility of, subjective norm regarding, and media influence regarding mobile use for communication purposes that influence the attitude toward the subjective norm and media influences of mobile use for shopping. These in turn positively influenced the consume's intention to use mobile devices for shopping. A Structural equation modeling analysis, using the data collected from a national online survey of 524 U. S. multichannel shoppers, confirmed the proposed model. The theoretical implications of these effects were discussed and managerial suggestions were made for both academicians and practitioners.

This paper is a study on what kind of effect non-verbal communication in mobil electronic commerce has on purchase intention and visual attention. For this purpose, the screen of mobile shopping mall produced arbitrarily was exposed to the experimental group and the control group. The experimental group was exposed to the screen of mobile shopping mall that expressed non-verbal communication making use of cinemagraph images and the control group was exposed to the screen of mobile shopping mall based on still images. For the study, survey research and experimental research were conducted simultaneously. Data of survey research were analyzed by MANOVA and t-test, and by using eye-tracker experimental research recorded the duration of time that the subjects stared images. The results of experiment show that in non-verbal communication the experimental group that saw cinemagraph images recorded shorter average staring time than the control group that saw ordinary images, and the cinemagraph had statistically significant effect on visual attention as well. And it was analyzed that non-verbal communication had significant effect on the purchase intention of the experimental group, but had no effect on the purchase intention of the control group. The results can be interpreted that the people who saw cinemagraphs in mobile shopping environment had spent shorter time in seeing products than the people who saw ordinary images, but still the former came to have purchase intention on the products. The results of the present study can be useful for marketers who try to sell agrifood in mobile environment.

While there have been a lots of researches focusing on the commitment to shopping site in online commerce area, few studies suggested the results on the relationships between users' characteristics including demographic and shopping characteristics and commitment to mobile shopping site. Therefore, this study investigates whether the level of mobile shopping site commitment will vary by users' characteristics such as gender, age, shopping time, and shopping scale. This study suggests, from the statistical analyses on 230 questionnaires, that there are differences in level of shopping site commitment among the respondents grouped by age, shopping time, and shopping scale except for gender. The study proposes various implications for future research on the management of shopping site commitment in mobile Internet environment.

Purpose Unlike advertising through the traditional media targeting unspecified number of people, the base of mobile environment using smartphone has expanded so that many companies can classify prospective customers according to their purpose, thereby enabling efficient targeted marketing with low cost. Design/methodology/approach This study has investigated how can marketing strategy be influenced by the price promotion type (immediate discount/delayed discount) and message framing (positive/negative) according to time pressure (low/high). Hypotheses are set through the consideration of prospect theory, endowment effect, framing effect, regulatory-focus theory, and time-pressure theory. Findings The results and interpretation of this study are as follows. First, it was found that the influence of the delayed discount on the purchase intention was larger than the immediate discount. Second, negative/loss frame messages have more influence on purchase intention than positive/profit frame messages. Third, when the price promotion type is delayed discount, the effect of the promotion message on the purchase intention when it presented by negative/loss frame is greater than the other cases. The implication of this study is that it can be used as a basic data for establishing a strategy to maximize the effectiveness of promotions effectively considering potential buyers of mobile commerce environment.

As the wireless communication technology developed, the Electric Commerce using a mobile was activated. WPKI was developed in order to guarantee the stability of the Electric Commerce but it is difficult to be ensured for the safe PKI service which is the same at the wire communication in the technical because of restriction of the mobile terminal. In this paper, we propose the authentication system for the electronic financial service which is safe and is effective in consideration of the restrictive characteristic of the mobile terminal. Moreover, the encryption algorithm for the safe electronic signature is proposed. In WPKI, this makes the cross certification of each certificate authority possible. Moreover, a stability was enhanced through the signature authentication using KCDSA and SEED algorithm.

A new secure network communication technique that has been designed for mobile wireless services, is presented in this paper. Its network services are mobile, distributed, seamless, and secure. We focus on the security of the scheme and achieve anonymity and reliability by using cryptographic techniques like blind signature and the electronic coin. The question we address in this paper is, "What is the best way to protect the privacy and anonymity of users of mobile wireless networks, especially in practical applications like e-commerce?" The new scheme is a flexible solution that answers this question. It efficiently protects user's privacy and anonymity in mobile wireless networks and supports various applications. It is employed to implement a secure e-auction as an example, in order to show its advantages in practical network applications.
