Kim, Kyung-Hee ; Park, Tae-Jun ; Jang, Woo-Jung ;
Journal of Digital Convergence, volume 10, issue 5, 2012, Pages 7~17
This paper identifies the determinants of adoption and diffusion of e-government services, and examines the causal relationship among the variables of adoption behavior. The main findings, based upon survey responses from service users, are as follows: first, both the value of service and the socially influencing factor have the positive effect to the intention of utilizing services. Second, the socially influencing factor has the indirect effect to the intention of utilizing services, because it positively affects the value of service. The interaction factors, however, do not directly affect the intention of utilizing services. These interaction factors indirectly affect the intention of utilizing services through the path which increases the value of service, and its effect is larger than the socially influencing factor.

An Exploratory Study of the Relationship between Smart Learning and Smart Work: The Use of Personal Laptops by Graduate Students in a Smart Campus Environment
Kim, Young-Woo ;
Journal of Digital Convergence, volume 10, issue 5, 2012, Pages 27~35
The importance of smart learning (SL) has been emphasized in schools. Additionally, the significance of smart work (SW) in improving business performance has gained much attention among industries. From theoretical, technological, and environmental perspectives, SL and SW are somewhat similar. Therefore, a case study was performed to find a way to link SL and SW, and a linking model was proposed for this purpose. Because laptops are considered a pivotal element in the technological aspect of SL, graduate students' use of personal laptops in classes (Bring Your Own Laptop, BYOL) was investigated. The results showed that the students reacted positively to the idea of using personal laptops in class and that they expected to learn IT skills more effectively this way. They listed being able to study even after class and the easy accessibility of relevant data as the strengths of BYOL. However, they cited the heaviness of the laptops and occasional loss of focus during classes as the weaknesses of BYOL. Thus, this study showed the possibility of that students who experience SL can perform better in an SW situation. Therefore, if a policy is enacted that allows students to efficiently use laptops, a greater number of educational achievements will be attained on smart campuses and, subsequently, a greater number of smart workers will be produced.

On June 29th, 2010, a cross-straits "Economic and Cooperation Framework Agreement" (ECFA) is signed between China and Taiwan. This pact seems to be the greatest step forward on cooperation between the two sides, reflecting China-Taiwan thaw. As these countries are especially economically interdependent, great economic incomes and security benefits are expected for both sides after cooperation. this development of enlightened cooperation between China and Taiwan, gives many implications for Korea, the two divided countries. Recently, relation between north and south Korea is developing in an entirely different situation compared to the former Kim Dae-Jung or Roh Moo-hyun administrations. But exchange between north and south Korea has not been stopped, though reduced. This reflects the necessity of exchange of the north and the south, and this means that making preparation for the efficient conduct of exchange is needed. So in this study, we consider the China-Taiwan exchange and cooperation development carefully as a model for exchange and cooperation of the north and south Korea, and sought realizable ways to exchange and cooperate between the north and south Korea, which is also a win-win strategy for northeast Asia.

Journal of Digital Convergence, volume 10, issue 5, 2012, Pages 89~103
This paper analyzed the effect of learning motivation and conation(endurance, effort) on the consultant' entrepreneurship(innovativeness, proactiveness, risk- taking) and competencies(ability, knowledge, attitude), and the mediating effect of the entrepreneurship on the consultant's competencies. The result shows that the learning motivation and conation have a positive impact on the partial factors of the consultant's entrepreneurship(innovativeness, proactiveness) and competencies(ability, knowledge), but not impact on the risk- taking and the attitude. Innovativeness and proactiveness have an positive impact on the consultant's competencies, but not the risk-taking. Innovation and proactiveness fully mediated the effect of learning motivation on the ability, and partially mediated on the knowledge. The effect of learning conation on the ability and knowledge was partially mediated by the innovation, not by the proactiveness. This study shows that the management of the learning motivation and conation, the education of entrepreneurship(innovativeness, proactiveness) are very important for the cultivating the consultant' competencies.

Journal of Digital Convergence, volume 10, issue 5, 2012, Pages 215~222
A smart phone has functions of both telephone and computer. The wide spread use of smart phones has sharply increased the demand for mobile commerce. The smart phone based mobile services are available anytime, anywhere. In commercial transactions, a digital signature scheme is used to make legally binding signature to prove both integrity of commercial document and verification of the signer. Smart phones are more risky compared with personal computers on the problems of how to protect privacy information. It's also easy to let proxy user to authenticate instead of the smart phone owner. In existing password or token based schemes, the ID is not physically bound to the owner. Thus, those schemes can not solve the problem of proxy authentication. To utilize the smart phone as the platform of mobile commerce, a study on the new type of authentication scheme is needed where the scheme should provide protocol to get legally binding signature and not to authenticate proxy user. In this paper, we create the mobile ID by using both the USIM and voice template of the smart phone owner. We also design and implement the user authentication scheme based on the mobile ID.

Journal of Digital Convergence, volume 10, issue 5, 2012, Pages 251~266
Location Information is an information about a place where an individual exists or had existed. As smart phones are popularized, location information becomes more than simple information about the place. As a result, services using an individual's location information became the trend. However, problems arising from discharging Private Information can damage an individual, because it causes financial and economic loss but also detects individual's location and route directly. In realities, the guide that regulates Location Based Service for administering Private Location Information is insufficient. Therefore, this paper proposes check items, which contain standards of judicial action, financial loss ratings, importance of Private Location Information, and criticality of check lists, during the Private Location Information audit at the level of analysis, design, and management of the Information System, in order to prevent the infringement and disclosure of the Private Location Information. Moreover, the proposed check items were verified for its suitability by the professionals' survey.
