Kim, Hee-Kyung ; Kim, Dug-Mo ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 1~9
The digital signal is terminated on Dec.31, 2012. But most of the analog cable subscribers are faced with the difficult reception of the digital because the government has defined the terrestrial broadcast as digital transition obligation operators. It is estimated that half analog of the total pay-TV subscriber that is approximately 10million households that are directly receiving terrestrial signal must hold the digital TV or DtoA convertor to transit digital. But cable system subscriber should buy Set-top box that are expensive and pay the expensive rates. The cast of analog cable subscribers has been classified as a group that can cause the most damage after digital switch. This study investigate the problem, and cause, solution of the analog cable subscribers that are placed in the blind spots of the digital switch.

Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 11~21
Though adolescents have the skillful ability to use internet and use it extensively, they have experienced sexually less than adults and are hard to have the right viewpoint toward sexuality. Because of these adolescents' characteristics, internet pornography cause them serious troubles with their sexual behavior. Based on the viewpoint, this research explores structural relationship among their sexual orientations, exposure to internet pornography, the sexual drive and behavior with PLS path modeling analysis. In result, androcentric and pornography-friendly sexual orientation have an influence on the exposure to internet pornography, in turn, the exposure to internet pornography affect the sexual drive and behavior directly and sexual behavior indirectly mediated by the drive. The significance of this research is to identify fact that sexual orientations, reconceptionalized from previous researches's dependent variables, predict the exposure to internet pro-pornographic and is to identify a popular myth indirectly that the exposure to internet pornography stimulates sexual drive to cause behavior, in turn leads to sex crimes finally.
A Study on Sex Offenders Registration and Notification Act of the U.S.
Lim, Hee ; Park, Ho Jung ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 23~42
Congress enacted the sex offender registration and notification act in order to prevent sexual offenses and protect public safety in the U.S.. Namely, in 2006, the Jacob Wetterling Act and Megan's Law were integrated into the Adam Walsh Child Protection and Safety Act as a comprehensive sex offender supervision and management scheme. The AWA aims to eliminate loopholes and gaps formed by inconsistent state laws and statutes as well as to provide the federal standards for sex offender registration and notification. However, the AWA contains over-inclusive sex offender registration requirements and punishments. For this reason, the implementation of the AWA may cause problems for states, sex offenders, and citizens, both as taxpayers and as beneficiaries of the AWA. Therefore, the AWA that does not differentiate between violent and non-violent offenders should be reformed to allow law enforcement officials to focus on sex offenders convicted of violent and heinous crimes. That is, the AWA should not apply to sex offenders who are not dangerous, not likely to recidivate, and who committed non-violent crimes. In addition, because the AWA requires juvenile offenders to registrate on public notification forums, it may result in a greater risk to community safety and potential risk of reoffense. Accordingly, juvenile offenders convicted of non-violent sex offenses and not likely to recidivate will be provided appropriate treatments to be rehabilitated as members of community.

Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 91~101
The purpose of this study is to empirically verify the relationship between supply chain flexibility(process flexibility and logistics flexibility) and competitive advantage strategy(cost, quality, lead time). To accomplish these purposes, the relationships among supply chain flexibility(process, logistics), competitive advantage strategy(cost, quality, lead time) were modeled based on the studies conducted in the various areas. In order to collect the related data the questionaries of 500 were distributed to the employees working at the manufacturing industry in the area of Gumi. The collected data were analyzed with SPSS 18.0 for Windows. This study used the statistical techniques such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, multi regression analysis. The results of the study show that process flexibility had positively significant effect on low cost strategy and high quality strategy and logistic flexibility have positively significant effect on delivery speed strategy. However, it was found that process flexibility did not have the significant effect on delivery speed strategy, and the logistic flexibility did not have the significant effect on low cost and high quality strategy. Thus, it is expected that each enterprise can maximize corporate strategies by applying different flexibility strategy depending on the competitive advantage strategy.
A Study of improving reliability on prediction model by analyzing method Big data
Song, Min-Gu ; Kim, Sun-Bae ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 103~112
Traditional method of establishing prediction model is usually using formal data stored in Data Base. However, nowadays advent of "smart" era brought by ground-breaking development of communication system makes informal data to dominate overall data, such 80% in total. Therefore, conventional method using formal data as establishing predicting model would be untrustworthy means in present. In other words, it is indispensible to make prediction model credible including informal data(SNS, image, video) and semi-formal data(log data). In this study, we increase credibility of predicting model adapting Bigdata method and comparing reliability of conventional measurement to real-data.

Lee, Seo-Joon ; Lee, Tae-Ro ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 159~167
Development of infusion pumps enabled injecting medical substances continuously and automatically to patients in hospitals. However, in cases when patients encountered emergent situations when moving to other areas, no clear measures were taken. The problem is that even the lightest error in injecting medical substances could be critical to the patient. That is why we proposes a remote infusion monitoring system using wireless network and RFID technology in this paper. When a problem occurs in the infusion pump, the medical personnel are informed of their patients' emergent situation and location information via wireless network so not only can they swiftly and accurately provide medical services but also can prevent safety accidents due to infusion pumps.

An Evaluation of an Information Sharing Workflow Using Data Provenance Semantics
Lee, Choon Yeul ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 175~185
For effective information sharing, data provenance semantics need to be managed effectively. Based on a scheme to represent data provenance semantics, we propose a model to calculate information sharing costs. Information sharing costs are derived from probabilities of type I and type II errors that occur in organizational information sharing, costs related to these errors, and information sharing distances between organizational units which are determined by information sharing workflows. We apply the model to various types of information sharing workflows including departmental information systems, hierarchical information systems, a hub and a stand-alone system. The calculated information sharing costs show that the hub with data standardization is best in information sharing; however without standardization its information sharing cost deteriorates to that of a departmental information system. And, any information sharing workflow is better than a stand-alone system. It is proved that the model is useful in analyzing effectiveness of information sharing workflows and their characteristics.

The process for adjustive media as design method with feedback
Cho, Hyun-Seung ;
Journal of Digital Convergence, volume 11, issue 6, 2013, Pages 311~317
Most of the existing interactive arts or entertainment systems consist of the following three steps: 1. the system's prompting the action of the participant, 2. action of the participant, and 3. response of the system. They do not presuppose these successive processes are performed continuously and repeatedly, and they are designed to express the concept of the work in each interaction. The opposite approach is to transmit the concept of the work in a continuous and repeated experience. The authors propose "Adjustive Media" as a type of work based on this approach. Adjustive Media has a spiral model with feedback. When participants experience the work repeatedly, they can recognize the difference of results between each interaction, and they can under- stand more closely the intent of the designer. This paper will propose 3 design processes for Adjustive Media as design method, and will introduce the prototypes of Adjustive Media.
