Park, Sangjung ; Koh, Chan ;
Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 47~58
This study selects political and military decision factors of Participatory Government's Wartime Operational Control(OPCON) Transition and analyzes, both quantitatively and qualitatively, the effects and relations between those factors. Previous research utilizing the Analytic Hierarchy Process(AHP) selected their decision factors based on academic data and field experience, requiring more objective analysis of the factors. For this study, we conducted a survey among security subject matter experts(SME) both online and offline. The results show that OPCON transition's decision factors were to 'recover military sovereignty', 'set the conditions for peaceful reunification' and 'improve ROK image through enhancing national power' which differs little from the previous AHP method studies. It also showed that 'recover military sovereignty' and 'set the conditions for peaceful reunification' had no relationship to each other and that the key factor that decided the OPCON Transition was actually 'recover military sovereignty' which represents the interest of the liberal party in ROK. This study finds its meaning by analyzing the decision factors of Participartory Government's OPCON Transition thorugh Delphi and DEMATEL method.

The evolution of cloud computing service over the recent years is potentially one of the major advances in information and communication technology. However, if cloud computing service is to achieve its potential, there needs to be a clear understanding of the various issues such as service security, performance and availability and so on, both from the perspectives of the providers and the consumers of the cloud service. As more and more information on individuals, companies and public sectors are placed in the cloud service, concerns are beginning to grow about just how safe and reliable an environment it is. In order to overcome these situations, the Korea cloud service certification system and U.S. FedRAMP were performed in each country. This paper aims at comparing and analyzing between Korean cloud service certification systems and U.S. FedRAMP and describing the difference between them. Eventually, we propose the improvement strategy of Korea cloud service certification systems based on the comparison results between them.

Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 87~92
In the early 2012, European Union proposed new legal framework, including the right to be forgotten, for the protection of personal data. The new Proposal articulates kind of sweeping new privacy right and there has been debates on its potential threat to free speech in the digital age. While the situation is similar in Korea, I want to introduce the right to be forgotten in the Proposal. Then, I will analyze current legal system in Korea regarding the new privacy right and suggest some guidelines in searching direction for the coming legislation with respect to the right to be forgotten. The right to be forgotten should not have been promulgated without considering fully its effect on the free speech, especially in the society where the voice toward direct democracy or movement toward participation of the citizen, mainly through cyber space or Social Network Services, has risen much higher in Korea. Especially, the new right seems not to cover the control of data subject on a third party where the third party expressing his opinion by posting himself other's personal data on his blog or others.

Information system operation principles were recently established in order to provide high quality service and efficient operation audit of IT outsourcing. Operation managements are done based on these principles. Therefore, information operating management process, which refers to itself, is established. Information system operation audit requires a constant audit regularly, which is different from construction/development audit that is done only once. As operating management process changes, operation audit guidelines should be updated and improved. Therefore, this paper proposes IT outsourcing operation audit model with IT outsourcing achievement management as a focus. IT service domain was referred in order to propose information system operation audit model and check lists, which are based on IT outsourcing operation managements such as planning, making strategies, contract, service, and management. The deduced audit model and check lists verified suitability of the proposed model by experts' survey.

Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 197~202
Block Train Services(BTS) are actively studied in many countries for higher productivity and eco-friendly systems of inland freight distribution. However it is difficult for an ordinary student or researcher to approach for understanding and studying BTS because rail transport is operated monopolistically by Korea government and most freight information in each company belongs to its business secret due to the industrial characteristics. For such reasons, the study aimed to develop a BTS simulation model that it supports understanding and strategic decision required for BT operation. To build the result, expert depth-interviews were conducted with analysis of relative references through the domestic representative BT operating company K. The simulator refers to the Busan NewPort-Uiwang section and functionally, it supports scenario generation and analysis on BT operation. It makes a contribution to study a new type's technological application for learning and strategic analysis of BTS.

A Study on the Factors Affecting Diffusion of Open Source Software
Kwon, Moon Ju ; Park, Seong-Taek ; Kim, Tae Ung ;
Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 225~234
OSS(Open source software) pursues the freedom to have access to open source and offers several advantages, over the proprietary software, to enterprises. Based upon Rogers(1995)' innovation-diffusion process, we assume that attributes of innovations includes five characteristics of innovations: relative advantage, compatibility, complexity, trialability, and observability, and that firms' perceptions of these characteristics predict the rate of adoption of OSS. To test this hypothesis, we presents a survey result from 201 companies and institutions concerning the use of OSS. Statistical analysis shows that adoption is highly correlated with each of those characteristics of innovations, but the regression analysis indicates that only compatibility and observability have effects on the adoption of OSS. This implies that intrinsic value of OSS is important, but unless the appropriate service package for improving IT environment is provided, it is not easy to change the perspective of corporate customers more favorable toward OSS use. As a conclusion, the academic and practical implications are also discussed.

Causal Relation Analysis of the Motivation and Benefits Factors Affecting Customers' Purchase Intention of Counterfeit Goods
Yu, Seung Yeob ;
Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 287~293
The present paper attempts to account for customers' purchase intention of counterfeit goods. Based on some previous analyses, we have set up a structured model for analysis with a hope to identify the relationship between benefits from using counterfeit goods and motivational factors to purchase them. It is found, first of all, that motivation for ostentation significantly influences personal benefits from using the counterfeit goods. Second, we also find that motivation for satisfaction does not exert any direct influence on the factors of benefits, though it affects decisions to purchase. Third, motivation for practicability has significant influence on personal and, more strongly, on economic benefits. Fourth, quality has significant influence on both personal and economic benefits. Again, this factor is also more closely related with economic benefits than with personal ones. We hope that we will be able to provide practical tips for those who design and plan public service advertisements that intend to reduce purchasing of counterfeit products.

Park, Seong-Taek ; Kim, Young-Ki ;
Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 315~321
Since technological innovation is such an important factor that it can determine a company's economic growth and competitive enhancement, all the companies make lots of investments and efforts for technological innovation. As outcomes of technological innovation, there are patents, trademark and copyrights, etc. and they are mostly approved as a legal right called 'Intellectual Property Right'. To activate such an intellectual property right, financing techniques are needed for enterprises to raise funds through collaterals, such as technological and intellectual patents. In reality, however, any IP-related financial system is not really activated due to the lack of surety-related regulations in Korea. Thus, on the premise that it is important to carry out an objective and reliable valuation on IP as a collateral for the activation of IP finance, this study intends to investigate various different methods of patent valuation needed for IP finance.

Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 323~329
This study examines the anchoring effect and the adjustment process of two variables(verbal information, cognition load) with snack products. In the results of this study, 1) we found the anchoring effect because the respondents predicted more the number of real units(goraebap) on the packaging painted 25 units than 5 ones. 2) We confirmed the moderating effect of verbal information. The difference of the number of real units predicted between the two packaging was decreased when the visual information was in company with verbal information. And 3) the moderating effect of cognitive load appeared because the more cognitive load was, the less the difference of the number of real units predicted was. This study has shown that we can reduce the errors and biases by adjusting the information frame or the cognitive load. This research provides a theoretical-practical implications to the marketing staffs like packaging designers as well as scholars to study consumer psychology.

Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 343~349
Usage control models are the new breed of access control models that allow description of comprehensive policies for usage of protected content. In this paradigm, decisions regarding access to objects are not limited to request time only. It is coupled with the usage of the protected objects and becomes a continuous process carried out in parallel to the usage. The realization of usage control has been a long standing research problem to overcome the issue of loss of control in secure document dissemination. With the emergence of cloud computing, documents are stored in the cloud, the document viewers and editors themselves reside in the cloud and are accessed from thin clients such as browsers. We note that such scenarios provide an ideal opportunity for the realization of usage control for securing the usage of documents based on the stakeholders' policies. In this paper, we proposed Multimedia Content Management (MCM) for a better realization multimedia content in the cloud based applications. We designed a robust architecture to provide fine-grained control over usage of protected objects through the use of emerging cloud computing paradigm. We present the design principles for this realization and discuss our proposed architecture.

Han, Hyun-Soo ; Moon, Tae-Eun ;
Journal of Digital Convergence, volume 10, issue 11, 2012, Pages 403~418
In this paper, we attempted to theorize the synergy effect between the value creating attributes for digital convergence model in the service industry. Our investigation is based upon contingency fit theory to understand the strategic fit for the two inherent value attributes of fixed and mobile value, as well as resolving fundamental limitations of service processes. Empirical validation of the derived research model is analyzed using hierarchical regression method. The results indicate that the relative advantage of each value creating attributes are strongly associated with the characteristics of domain service industries, and compatibility is critical to user adoption of convergent service model. Moreover, the less significant statistical impact of the synergy between mobile and fixed value attributes and others implies that each value attribute uniquely contributes to particular IT convergence model, which thereby offers critical insight that focusing the convergent value in conjunction with specific application domain is the most appealing managerial focus. The findings provide useful insight for the further research in IT based industry convergent business model areas.

Objectives: The purpose of this study was to determine whether the sacrooccipital category II blocking technique may improve abdominal muscle endurance and alleviate shoulder pain caused by pelvic tilting. Methods: A total of 50 subjects diagnosed with category II sacroiliac joint instability and lower back pain were randomly assigned to the control or treatment group. The sacrooccipital technique category II blocking procedure (2-min duration) was performed 3 times a week until the category II indicator of joint instability had subsided. The control subjects were subjected to a sham procedure of equal duration and frequency. We assessed abdominal muscle endurance using the partial curl-up test and shoulder pain using a visual analogue scale, before and immediately after the intervention and 2 weeks after the intervention. Results: On two-way analysis of variance with repeated measures on time factor, significant treatment and interaction effects on muscle endurance were found. A significant interaction effect, but not treatment effect, was found for shoulder pain. Post hoc test showed that the shoulder pain was reduced immediately after intervention (treated group) and 2weeks (control and treated group) after the intervention as compared to before the intervention. Conclusions: This study suggests that sacrooccipital category II blocking can be used to alleviate shoulder pain caused by pelvic instability. The mechanisms behind the long-term benefits may include an increase in abdominal muscle endurance.

"Information", which is circulated in society by information technology development represented by computer, has brought innovation not only to physical civilization, but also deep into our daily lives. This is to say that information has brought fundamental change to its form of existence, and value system through being faster regarding the circulation and the way of management being diverse. As time goes by, this kind of change would stimulate more changes to be made as the development of scientific civilization. Therefore, informatization is one of the important characteristic that defines modern society's essence, but on the other side, information has been taken advantage of that temperament and abused in a lot of different ways. "The Law Regarding Computer Network Diffusion Expansion and Usage Promotion"(1986), as a counterplan of informatization is our nation's first Act about informatization, which enacts national policy and system about this issue. Since then, many laws has been enacted down to "Private Information Protection Act"(2011), forming a comprehensive system. The basic background of these laws are based upon the premise that even if the place where the information is managed is virtual space, rules that are considered valid in the real world should be basically applied in the virtual space. Therefore, the violation of the law in the real world is also considered the violation in the virtual space. This direction of current law regarding information is shared with both the theories and the reality. However, current law system and notion are based upon the premise that the law regards material objects, thus the characteristic of the information, which is "Immaterial Being" is not reflected. Also, the management and approach to this issue is allopathic, exposing many problems. Thus, this paper examines the way of protecting information stipulated in the current law, contemplates its protection scope and limitation, and seeks the direction of the improvement, based on the critical mind explained above.
