This study is the first model to apply the concept of media engagement to a political campaign by which the voters` mind toward the supporting political candidates, are read. Thus it provides the theoretical and practical implications to the political campaign, and eventually contributes to the development of democracy. For these objectives, the total of 729 people who have the right to vote were telephone surveyed using the peoplemeter, CATI program in the 18th Presidential Election (12 areas including Seoul) of Dec. 19th 2012, and Re and By-election of April 24th 2013. Research question is to examine how the 5 attributes of the media engagement (interest, immersion, relevance, satisfaction and participation), play a role as the moderating variables in cross-correlation, socio-economic status and media properties. The result shows that of the five properties of media engagement, the relevant factor is the important parameter of mediating variable to the causal relationship. The media usage (TV, SNS, print media), socio-economic status (gender, age, income, marriage and area), involvement and the Presidential Election, and Re and By-election are also effective in the five attributes of media engagement. These results suggest that the a study model can measure the campaign effectiveness. This study will contribute significantly to the development of politics, election, media, advertising, and public relations area as well as to promote interdisciplinary research.

DOI : 10.14400/JDC.2014.12.5.45
This study takes the position that present after-school classes affect the development of children`s sociality and self-esteem, and aims at comparing, analyzing and grasping the differences in sociality and self-esteem of the children who attend after-school classes and those of the children who don`t. First, when the differences of sociality were analyzed between the children going to after-school classes and those who weren`t, it was revealed that those who attended after-school classes had rather lower level of sociality than those who didn`t, but there were no statistically meaningful differences. Second, when the differences of self-esteem in regard to whether children took after-school classes or not were examined, those who were taking after-school classes were analyzed to have lower self-esteem than those who weren`t. The study results showed that the children who went to after-school classes had lower sociality and self-esteem compared to those who didn`t. Taking this fact into consideration, different ways should be found to improve their sociality and self-esteem. In addition, programs need to be developed and introduced so that after-school classes can not only fulfill their original purposes of protecting and guiding children, but also continuously elevate and maintain children`s sociality and self-esteem.

Journal of Digital Convergence, volume 12, issue 5, 2014, Pages 57~68
DOI : 10.14400/JDC.2014.12.5.57
This article analyses frame transition of personal information leakage in Korea from 1984 to 2014. In order to investigate the transition, we have collected newspaper article`s titles. This study adopts classification, text network analysis(by co-occurrence symmetric matrix), and clustering techniques as part of social network analysis. Moreover, we apply definition of centrality in network in order to reveal the main frame formed in each of four periods. As a result, accessibility of personal information is extended from public sector to private sector. The boundary of personal information leakage is expanded to overseas. Therefore it is urgent to institutionalize the protection of personal information from a global perspective.

This study deals with the digital policy proposal through the path modeling study on the effect of the strength of weak ties & emotional perception leading to the user`s satisfaction, WOM between game users, and the verification on the effect of the emotional real name SNS on the social network game`s diffusion. Researcher confirmed that the effect of the strength of weak ties & emotional perception led to the user`s satisfaction, WOM of SNG. Even though weak tie, researchers estimate that the users emotionally interact with the real name relation effect of SNS. And effective factors for WOM are not a tie relationship or emotional interactivity of weak tie antecedently but user`s satisfaction. As a result, though antecedent factors (weak tie & interactivity) had a positive effect as real name SNS, eventually powerful factor of making buzz was the SNG user`s satisfaction. Thus researchers expect the practical policy proposition for government & corporation, which means SNG service providers more carefully manage the service satisfaction for WOM with SNG user`s experience.

In general, at the relationship between claim and obligation if debtor does not fulfill its obligations arbitrarily the creditor can claim to debtor such as lawsuit. It means, despite the debtor ordered payment through the judgment, if debtor disobey that judgment, compulsory execution can be performed by the force of the country. In the end, fulfillment of obligation is enforced by national authorities in principle. However, exceptionally, even it established as a valid debt, if debtors fulfill themselves, they may not be protected from the national authorities. That is the natural obligation. The natural obligation originated from the Roman law which enforces strict type legal system and it is exceptional phenomenon in modern civil law which is made up as that all the bonds are likely to recourse. Therefore, in Korean theory acknowledge that debt is natural obligation and there is no exception. However, there are still controversy about the presence and occurrence of natural obligation. So, in this paper, want to review about its extent and effect including the concept of natural obligation.

The competitiveness in today`s global market forces many companies to develop families of products to provide enough variety for the marketplace. The challenge when designing a product family is in resolving the tradeoff between product commonality and distinctiveness. Simultaneously it is necessary to consider environmental performance to design a product family as well as to shorten lead-times, improve quality and reduce costs. This paper proposes a metaheuristic algorithm based redesign methodology for green product family considering environmental performance. The proposed method uses a genetic algorithm as metaheuristic algorithm and green product family index (GPFI) to support green product family design. In addition, it provides the redesign methodology such as product family level and component level. A case study used table lamps as an product family`s example shows the verification and effectiveness of the proposed method.

Management consulting by a bank is expected to have a win-win relationship to the mutual development of the banks and client firms. Previous studies also claimed that consulting had a positive impact on the competitiveness and business performance of the firms. Nevertheless, few empirical studies were found to analyze the relationship and explain the result whether consulting had really enhanced the competitiveness and performance of the businesses after consulting. The present paper has empirically analyzed the impact of a management consulting by a bank on the business performance of the client firms and on the contribution to the bank. In terms of client firms, the financial results of the client companies such as stability, profitability and growth potential were compared before and after the consulting; in terms of the bank, the changes in the last three-month average outstanding of deposits and loans were measured and verified in order to measure the contribution of the client firms to bank. A significant effect was confirmed in this study of the consulting on the client firms` the debt ratio-an item of financial stability and sales growth-an item of the growth potential.

The purpose of this present study is to empirically analyze the variables affecting socio-economic performance of social enterprises. For this purpose of 107 enterprises, located in Seoul, was performed under the hypothesis that the authentication properties (authentication type, authentication year) of social enterprises will affect the socio-economic performance. The analysis showed that first; authentication type among the characteristics of social enterprises showed significant effects on the social performance. Second, authentication year among the characteristics of social enterprises showed significant effects on the economic performances. In addition, since the job-creating type showed higher social performance, it would be desirable to raise the certification rate of this type in the future. The analysis implied that longer the years of accreditation, the greater positive effects on the socio-economic performance of social enterprises was shown. Therefore, the present study suggest the need to diversify support policies according to the number of authentication years in order to secure sustainability by maximizing the socio-economic performance of social enterprise because the monolithic support is not very effective for continued growth and self-reliance of social enterprises.

The study considers the meaning of the composite images created when users capture present images over past images tagged location data in using the mobile augmented reality technology. The composite image through the location-based augmented reality technology is the result of matching the same location data between present images users are capturing and past images captured already. It is the new composite images that contain two different narratives-current and past in the same space and in real-time. We developed the mobile application implemented augmented reality technology and analysed the process that users create multi-layered narrative in the middle of capturing present image through augmented reality module. In addition, through the comparison with similar studies and applications of the augmented reality, we found that the key to give the multi-narrative in the composite images is the user`s participation to put its personal intentions in real-time capturing process. In further development, we`ll be able to utilize the application in order that users easily create multi-layered narrative composite image using cultural and personal records.

Recent advancement of USN technology has lent itself to the evolving communication technology for implantable devices in the field of medical service. The wireless transmission section for communication between implantable medical devices and patients is a cause of concern over invasion of privacy, resulting from external attackers` hacking and thus leakage of private medical information. In addition, any attempt to manipulate patients` medical information could end up in serious medical issues. The present study proposes an authentication protocol safe against intruders` attacks when RFID/USN technology is applied to implantable medical devices. Being safe against spoofing, information exposure and eavesdropping attacks, the proposed protocol is based on hash-function operation and adopts session keys and random numbers to prevent re-encryption. This paper verifies the security of the proposed protocol using the formal verification tool, Casper/FDR.

With 105 students conducted self-answering survey. It was conducted from June 12 to June 13 of the year 2013. Analysis has been conducted into 5-point scale in every parts of health promoting behavior, 4-point scale in self-efficacy. As a result of the study, after health education, the increasing level of the score was bigger than general university students in preceding research before education; from this, we could interpret that the peers who live together lead positive competition. For before-and-after affects of education, after-education score increased statistically significantly higher from before-education score for both freshmen and other students on every item of the survey. Especially, self-efficacy and stress management, which are the lower level of health promoting behavior, have shown statistic significance of health education. When comparing freshmen and other students, the item that showed significant difference was `self-efficacy,` and for both before and after health education, other students had higher score than freshmen. Based on the result of the analysis, for those who live together with group of people such as in-dorm students, group education is preferred to personal education; in addition, when selecting health education recipients, better achievement of education will be expected by primarily educating students who have lower level of self-efficacy and stress, especially freshmen who have lower self-efficacy level than other students in university.
