This study aims to collect and systematize indicators for each stage of digital transformation at the infrastructure level to accurately diagnose the current status of digital transformation in Korea and to serve as a reference for establishing a balanced digital strategy. In order to establish a framework for digital transformation of infrastructure, 19 indicators in three categories(tangible/intangible, data) were identified across three stages of digital transformation: computerization, digitization, and digital transformation, and 19 indicators in three categories were identified to study the changes in digital infrastructure. The main findings are: First, the digital transformation of infrastructure is at a high level, moving from digitization to digital transformation. Second, the scope of digital transformation policies is expanding as digital transformation is triggered, and additional policies on inclusion and social disparities should be prepared. It is also important to improve the regulatory environment, which is relatively undervalued. Third, as data becomes more important, it is important to develop indicators and measurements to strengthen digital competitiveness in terms of data infrastructure. This study is an exploratory study of the existing indicators, which can be used to conduct specialized research on the differences in the level of digital transformation by industry, sector, company size, age, gender, region, and group, and to study indicators for the expansion of digital transformation to social and industrial sectors. The expected effect is to deepen the process of understanding the interaction between each indicator, so that future digital transformation policies can be organized and promoted, and policy outcomes can be predicted and responded to in advance.

This study began with an assumption that virtual museum exhibitions will continue to be created in the future and more knowledge is required about designing effective virtual exhibit designs. This study explored the relationship between virtual exhibitions and visitor's opinions following the viewing of the virtual exhibit in order to determine the components of a well-constructed virtual exhibit design. To address the research problem, this study explored two aspects of virtual exhibit design: 1) what are the components of a well-constructed virtual exhibit, 2) how does viewing the virtual exhibit change visitors' opinions about both physical and virtual museum experiences. The methodology of the study employed surveys, interviews and observations as instruments of data collection. Twenty-five participants were given a survey prior to their viewing of the on-line exhibit, then they were given the opportunity to view the web-site and finally surveyed regarding their opinions. From the 25 participants, six were selected for observation to record behavior exhibited while they viewed the site. In addition, five were interviewed for a better understanding of their responses to various aspects of the virtual exhibit experiences. Data from the surveys was tabulated for descriptive percentages in order to identify numerical patterns of relationship. Observation data was analyzed for simple frequencies in categories of responses and interview data was tape recorded and transcribed into text files. Based on study results, recommendations were made for the future role of interior design in virtual space that stands independent from a physical building and resides only on the Internet.

The Media Law including Newspaper Law, Broadcasting Law and Internet Multimedia Law has been reformed in 2009. The main purpose of the reform was to allow media firms to gain a global competitive edge by opening doors to more investments that were nonexistent due to regulatory barriers. Also it aimed to contribute to an increase of employment in the media industry. This paper analyzes the impact that the Media Law reform of 2009 had on many media/contents company's future value by tracking abnormal returns gained during the period of the reform. The analysis with the capital market data of fifteen firms over a one-year period provided evidence that the new law has had an effect on the related firms' future value; however, the impact was shown to not be as significant in the long-term. This study has the significance in that it showed that the impact of the reform was not overall to the industry but given to the limited number of media company and confirmed the relatively strong effect of the unexpected events.

To develop the new network, the future network architecture is studied. Since the mobile devices are also advanced, they need for the mobility protocols. The one of the protocols, Fast handovers for proxy MIPv6(PFMIPv6) has studied by the Internet Engineering Task Force(IETF). Since PFMIPv6 adopts the entities and the concepts of fast handovers for MIPv6(FMIPv6) in proxy MIPv6(PMIPv6), it reduces the packet loss. Although the conventional scheme has proposed that it cooperated with an Authentication, Authorization and Accounting (AAA) infrastructure for authentication of a mobile node in PFMIPv6, it has the drawbacks such as high signaling cost and long handover latency. To reduce the signaling cost and the handover latency, we propose an enhanced authentication scheme in Fast handover for Proxy MIPv6. The proposed scheme reduces the handover latency and the signaling cost because the registration procedure and the authentication procedure are simultaneously performed. We also compare the proposed scheme with the conventional scheme in terms of the signaling cost and the handover latency.

Induced from government policy to boost regional economic competitiveness, regional informatization forming e-community has been the subject included in the various regional informatization master plans in Korea. However, few cases are reported for its successful implementation mainly due to the lack of profitable business model to encourage investment. On the other hand, most efforts to build smart apartments, part of the home networking in a broad sense, has been pursued from the different directions. Telecommunication giant such as Korea Telecom tries to find new source of revenue exploiting enhanced broad band technology. Also, construction companies started constructing housing complexes equipped with built-in high speed network infrastructure as a means to differentiation to other competitors. The contents providing community portal has become mandatory in the sense of bearing the cost from customer side who are willing to adopt those services for new smart house. Our research motivation stems from exploring critical value aspects of realizing the profitability of this emerging new business model, that is, industry convergence model. In this paper, mainly from the survey results of the Korean smart apartment complexes, we reported recent home networking services development in Korea, and value propositions from the business model perspective. Merged business model components of telecommunications, construction, and internet contents are analyzed to provide the insights for future directions.

Purpose: The purpose of this study is to develop a day care center model focused on public health institutions for the elderly residing in their homes. Method: Research design for this study was a mult-level research, which consisted of a related literature review, an Internet search for knowledge of the current situation at home and abroad, on-site interviews, questionnaires collected from a sample of residents in a rural area, and a key-informants approach. Results: 1) The subjects of service - Generalized service should be provided to the elderly, 65 years and older, regardless of their assets. 2) The contents of service - Providing pre-health oriented and post-social welfare service that can integrate and satisfy a wide variety of public health and welfare needs of the elderly would strengthen the health care service of a day care center for the elderly. 3) Delivery system - Basic-level local self-governments should become a central operating body, and establishing a properly adjusted delivery system to a rural area after considering the efficiency and the access of vulnerable rural areas is needed based on modification of 'a Special Law for Agricultural and Fishery Areas' (rural public health center>rural health sub-center ${\rightarrow}$ unified health sub-center ${\rightarrow}$ public health hospital (public health center) ${\rightarrow}$ public welfare office). 4) Facility - Public health facilities such as public health centers and sub-centers should be located in areas that can easily access the facilities. 5) Funding - For day care center for the elderly in local self-government, the central government should modify a relevant implementation of subsidy in and provide some facilities and service regardless of the degree of self reliance of local self-government. 6) Human resources - It is needed to guarantee the period of workers of a day care center for the elderly, at least 3 to 5 years, with considering their specialty on aged care and avoiding circulation based positions. Furthermore, appropriate specially trained personnel such as medical workers and social workers should be placed to take care of both health service and welfare through strengthening of 'rules of law of elderly welfare,' Conclusion: future research is needed to test the model through a demonstration study using a model which may be developed in the future and to standardize the appraisal criteria of people hoping to enter a day care center for the elderly.
