Despite the popularity of e-commerce, the understanding of preferred product types for information searches and purchase on the internet are not sufficient. This paper studies the effect of risk perception on information search behavior through online only, offline only, and on-offline together. Specially, this study classifies product types into search goods, experience goods, and credence goods. The study attempts to determine how the relationship between the perceived risk and the information search is influenced by the product knowledge level. The results show that the higher the risk perceptions about experience goods and credence goods, the more the consumer searches information through online and offline together when the consumer's knowledge level is low. When the consumer's knowledge level is high, however, the higher the risk perception regarding search goods, the more the consumer searches information through online only.

Online games are not only tools for enjoyment, they are also the linking pins connecting between the online and the offline worlds. The effects affecting other domains can be termed 'spillover'. With the process behaving as forward and reverse spillovers, there are interaction effects on online and offline behavior. However, there is little research dealing with the spillover effects from the offline to the online domain. This study concentrates on the individual behavior of online garners centering on offline dependence. With the purpose of finding the factors affecting both flow and immersion, I am interested in the moderator effect of offline dependence influencing both flow and immersion from social interaction. A research model is developed and a survey research is conducted from one of universities in Korea. The results show that flow is strongly influenced by skills, challenge, and social interaction, but immersion is only influenced by skills and social interaction and not challenge. The findings reveal that the moderating effect of offline dependence affects only the relationship from social interaction to the immersion on the lower offline dependence group.

Signcryption is a cryptographic primitive which offers authentication and confidentiality simultaneously with a cost lower than signing and encrypting the message independently. We propose a new cryptographic notion called Identity-based online/offline signcryption. The notion of online/offline scheme can be divided into two phases, the first phase is performed offline prior to the arrival of a message to be signed or encrypted and the second phase is performed online phase after knowing the message and the public key of recipient. The Online phase does not require any heavy computations such as pairings or exponents. It is particularly suitable for power-constrained devices such as smart cards. In this paper, we propose ID-based signcryption scheme and ID-based online/offline signcryption scheme where the confidentiality and authenticity are simultaneously required to enable a secure and trustable communication environment. To our best knowledge, this is the first ID-based online/offline signcryption scheme that can be proven secure in the standard model.

It becomes common thing that many customers buy the goods through the online shopping mall as internet grows very fast. The information cascades that happen when a person imitates the other's acts also it occurs in online. Many people buy the goods referring on other people's purchasing experiences and such cases are spreading more and more. Through numerous existing researches, the researches in association with this issue have been studied on the information cascades effect on offline or online separately. The research of comparing the information cascades effects from the offline word of mouth (WOM) and the online review has not studied yet. On that reason this study shows that the online review induces the information cascades. We also compared the effects with information cascades effects from traditional offline word of mouth. In result of this study, the following points have been concluded. Firstly, we examined that information cascades was occurred through both the online review and offline word of mouth. Secondly, the information cascades effect through the online review is greater than through the offline words of mouth. It means the company has to understand the importance of the online review and manage it. Thirdly, the information cascades effects are occurred differently in accordance with the goods brands. Therefore a company has to know whether its products is superior to the competitor's one or not.

The Amazon Go was the catalyst of O4O era. O4O is an advanced business model from O2O, which is the integration of offline service to online, especially through smart phone network. We also find the O2O strategy of digital contents companies such as Kakao and Line. This study examined the relation between online character experience and offline purchasing intention on related character products. The SEM was designed on the former study that based on the theory of user experience and brand attitude. The result of this study shows that the users' online experience have influence on the purchasing intention of offline related products and there exist the mediating routes of satisfaction of user experience, brand preference and brand reliability. There are no statistical support to the relation between satisfaction of user experience and purchasing intention. These points illustrate what marketers better to focus on transmedia strategies.

This paper concerns developing a real time on-line light facility management system using internet and building a database system for control box and street light. Also, we designed the system to minimize the disparity with the conventional management system by referring to an old management ledger format. Thus, the proposed method may enable the system manager to administer the light facility efficiently and to reduce manpower and maintenance cost.

온라인 교육은 오프라인 교육의 한 가지 방식의 교수방법에서 탈피하여 테크놀로지를 이용하여 교육의 효과를 높일 수 있는 구체적인 대안이 될 것이라고 예측되었다. 하지만 최근 들어, 사람이 아닌 PC와 의사소통을 해야 하기 때문에 집중력을 확보하기가 어렵고 인간미가 없다는 점등의 문제가 지적되고 있다. 이 문제점을 해결하기 위해서 교수자들은 온라인 환경이 갖는 장점과 오프라인 환경이 갖는 장점을 혼합한 통합교육을 시도하고 있다. 본 본문에서는 학습자들의 학업성취도와 수업만족도를 높이기 위해 온라인 수업과 오프라인 교실수업을 혼합한 통합교육에 멘토링 기능을 추가하여 학습모델 설계 및 학습 지원 시스템을 설계하였다.

This research was conducted in order to know how influential the acknowledgment of factors such as the quality of educational contents and the conducting of off-line lectures is in terms of effective learning for leaners. Based on the satisfaction-importance model of the multi-attribute attitude model, this study would like to clarify the degree to which the quality of on-line contents of on-line education and the simultaneous conducting of off-line lectures influences one's learning attitude. On-line contents satisfaction will evaluated through the three categories: audio lectures, video lecture and WEI lectures, which make up the quality of on-line contents. We would also like to do a survey on the transformation of learning attitudes when on-line and off-line lectures were conducted simultaneously.

In the 21st century, Internet information has a huge impact on citizens' participation in public policy process and trust in government. If the quality of Internet information is more positively perceived, the impact will be greater. In order to identify that causal relation, we construct the elements which make up the quality of Internet information and then analyze the impact of that quality on citizens' participation in public policy process and trust in government. First, positive perception about the quality of Internet information increases online participation and decreases offline participation in public policy process. Second, online participation activates offline participation significantly. Third, offline participation has a negative impact on trust in government. In sum, the quality of Internet information activates online participation, which, in turn, contributes a lot to an increase in offline participation and eventually weakens trust in government. On the other hand, the improved quality of Internet information weakens offline participation in public policy process and could contribute to the improvement of trust in government.
