This empirical study is to explain critical success factors for building effective regional IT cluster from the literature reviews which have some limitations, and is to suggest new key factors from the views of Regional Innovation System and Sectoral Systems of Innovation. For building successful cluster, the new key factors not only stress on regional networks, the spill-over of tacit knowledge through learning by interacting, institutions which contain regional custom, norms, established practices, culture, and characteristics from the Regional Innovation System, but also emphasize on heterogeneous agents who are interacting by each others from Sectoral Systems of Innovation. From these factors we suggest some strategies for building effective "Daegu IT Cluster" as following; making characterized IT brands which are selected and concentrated based on regional and IT sectoral characteristics, strengthening learning competence of tacit knowledge built in multiple heterogeneous agents network, establishing strong agent networks which are composed of universities, companies, institutes and government, and sharing the institution of mind-opening culture in order to correspond with environmental changes and link to other industrial clusters. By putting above strategies in force, the compatabilities of Daegu region are reinforced. Tacit knowledges spill over and the regional innovation competence are accumulated. Also IT cluster plays core role of employment in Daegu for long term. Especially, "Daegu IT Cluster" changes city's image from medium and small manufacturing city to new industrial city based on high technologies.

Landscape urbanism emerges as an alternative to the urban design theories of the past century, emphasizing landscape as an organizing principle, integrating the medium of different elements of the urban environment. However, ongoing criticism of the theory's lack of consideration for physical urban morphology has not supported the integrity of the theory. Large parks, which many proponents of the theory have referred to, possess valuable and interesting points in their design and management. This also shows the limitation of not being able to show the close physical relationship between open space and the city. In this study, the High Line project was analyzed to verify it as founded on landscape urbanism, providing that landscape urbanism drives the urban morphology on a small scale rather than a large one. This paper concludes that landscape urbanism should include small parks as one kind of study model with the small grained interaction between open spaces and the cities under this category to broaden and deepen the perspective. Also, the effort to analyze quantified and physical consequences of the theory through close observation should be followed to extract the design strategies to be applied to future projects.

Current medical delivery system in Korea has been distinguished into three types; primary medical facilities, secondary facilities, and tertiary facilities since 1989. This system prevents the waste of medical resources along with the maintenance of balance according to the medical treatment subjects. However, it is inevitable that the imbalance of the medical services among regions has been generated due to the concentration of the medical facilities on large cities. In this regard, this study attempted to evaluate the quality of the primary medical services, emphasizing accessibility and convenience targeting Jinju city, a small and medium-sized city, based on the distribution characteristics of the space. The study results show that cohesion index about the spatial distribution of the primary care facilities was 0~0.25. It conducted a correlation analysis between the location of the hospitals and users, based on the study results. Finally, it is demonstrated the correlation between the location of the hospitals and users tended to be low, while, the cohesion of the Oriental medicine clinics was high in other treatment subjects, and the accessibility to the Oriental medicine clinics was the highest because most Oriental medicine clinics were distributed to the places where users were many. However, on account that the locations of the medical facilities and users were varied in other treatment subjects except for the Oriental medicine clinics, problems were generated in terms of the accessibility. Therefore, it is judged that the preparation of the measures to improve the selection of lots in consideration of users, who use the primary medical services, is required.

The purpose of the study is to propose a policy implication of urban logistics in the Incheon metropolitan city. To attain the aim, it reviews new characteristics that Logistics Policy Fundamental Law(LPFL) published by government 2009 suggests and studies the previous papers like Logistic Fundamental Plan(LFP) of other metropolitan cities. After that it proposes a policy implication through benchmarking of urban logistics plan at Tokyo city not only located at a capital area at Japan but also including port and airport. The results are as follows. Firstly, field survey studies of the "LFP" every five years will need to keep pace with "Urban Fundamental Plan"(UFP) having designed to all cities legally every ten years. Secondly, Incheon will be required to create value-added logistics, making best use of third-party logistic companies to small-medium sized businesses along with the age of green. Thirdly, LFP needs to be performed through a mutual cooperation and adjustment among Incheon, Gyeonggi-do and Seoul and in this regions eco-friendly companies performing related logistic activities have to be followed executive and financial supports. Lastly, it will be obliged to develop a evaluation management index to understand the advancement level through a feedback system.

Medium and high-resolution optical satellites have proven their effectiveness in detecting wildfire areas. However, smoke plumes generated by wildfire scatter visible light incidents on the surface, thereby interrupting accurate monitoring of the area where wildfire occurs. Therefore, a technology to extract smoke in advance is required. Deep learning technology is expected to improve the accuracy of smoke extraction, but the lack of training datasets limits the application. However, for clouds, which have a similar property of scattering visible light, a large amount of training datasets has been accumulated. The purpose of this study is to develop a smoke extraction technique using deep learning, and the limits due to the lack of datasets were overcome by using a cloud dataset on transfer learning. To check the effectiveness of transfer learning, a small-scale smoke extraction training set was made, and the smoke extraction performance was compared before and after applying transfer learning using a public cloud dataset. As a result, not only the performance in the visible light wavelength band was enhanced but also in the near infrared (NIR) and short-wave infrared (SWIR). Through the results of this study, it is expected that the lack of datasets, which is a critical limit for using deep learning on smoke extraction, can be solved, and therefore, through the advancement of smoke extraction technology, it will be possible to present an advantage in monitoring wildfires.

The platform concept has been used for business operations in various forms: product platforms, transaction platforms and industry platforms. All these platforms have common characteristics of having 'core' that is reused frequently and 'peripherals' that are less reusable and changed often. Companies use platforms to enable efficient development and creation of product family, transactions and innovation. These platforms provide new opportunities for many small and medium-sized companies (SMEs) by bringing changes to traditional industrial structures focused on the products rather than platforms. The service robotics industry in South Korea is mainly composed of technology-intensive SMEs due to its small market size. Although these SMEs succeed in developing technologies, they have difficulties creating and expanding markets to sell products. Thus, this study addresses the characteristics and problems of the South Korean service robotics industry and analyses how ROBOPRINT, one of the SMEs in the service robotics industry, successfully creates and continuously expands the service robot market by adopting platform concept. The results indicate that ROBOPRINT has been applying two types of platforms: product and transaction platforms. First, ROBOPRINT created art robots that were apartment mural service robots. Rather than selling art robots, the company developed various robots such as painting robots, building exterior wall-cleaning robots by reusing the core technology of the robots. The company also developed various robots according to the buyers request. In addition, the company used the robots to directly provide apartment mural services for customers. This mural service has been extended into various areas, not only in apartments but also in soundproof walls, underground passages, and retaining walls. Besides, ROBOPRINT added new services continuously by developing technologies such as virtual reality. Second, ROBOPRINT mediated mural service buyers and mural designers. This platform reduced buyers' workload, which necessitates requesting mural services to ROBOPRINT and searching for mural designers. For designers, this opened up new opportunities to participate in the mural business. The platform attracted both mural buyers and designers who were scattered before. Finally, ROBOPRINT seeks to expand the platform's scope to outside company. To share internally reused ROBOPRINT's technology with other companies, the company participated in Daegu city's 'New Technology Platform Industry'. Furthermore, ROBOPRINT is trying to share the service platform by leasing robots to other companies. This allows external agents to develop technologies and provide services by reusing resources from ROBOPRINT. This study contributes to existing theories by showing that SMEs continuously create and expand markets by building various platforms. Moreover, it provides useful implications for practitioners by describing the firm's specific platform-building strategy.

Daejeon City has strived to support the SMEs to innovate technologies based on the capabilities of research and development of the Daedeok Innopolis. It is widely known that technological innovation is the key strategy of Small medium enterprises(SME) to survive and succeed in a market. This study aims to analyze the type and determinants of SME technological innovation in Daejeon. Even though most of firms are the small enterprises which employ less than 10 workers in Daejeon, the number of technology-oriented company per capita in Daejeon is highest in South Korea. The type of technological innovation is divided between product innovation and process innovation. The literature insists that technology-oriented small firm tends to implement product innovation rather than process innovation. SMEs in Daejeon also provided more output from product innovation than process innovation. The empirical analysis provided the results that the determinants of SME's technological innovation depends on its type. The scale of firm, R&D investment, and R&D employees positively influence product innovation of SMEs in Daejeon. However, the impact of R&D employees is not significant on innovating the existing product. Process innovation is positively affected by R&D investment and firm age. The study provides the policy implications to business supporting programs of Daejeon government. The business supporting policy of Daejeon government should focus on supporting each type of technological innovation to promote technological innovation by SME and consider strategies that focus on R&D investment and manpower support.

Limited studies examined Medical Aid recipients' perception for amount of medical use. This study aimed to identify self-perception(optimal, under and overutilization) for amount, and real amount of medical use, and to determine factors associated with the perception. Subjects were 2,489 Medical Aid recipients among top 2% overusers in 2005. 200 case managers(CM) managing them conducted survey. CM interviewed them using 2005 medical claiming data from the Health Insurance Review & Assessment Service and structured questionnaire. Despite of overusers, perception of overutilization was only 26.9% and 23.6% in Class I and Class II, and that of underutilization was 21.4% and 18.7% respectively. In Class I, monthly total outpatient cost per capita of overutilization perception in 2006 was 206 thousand won higher than 150 thousand won of optimal utilization. Amounts of outpatient visit-days and prescribed cases of overutilization perception were higher than those of optimal and underutilization(p <0.0001). In Class II, overutilization perception had more prescribed cases(p 0.004). After adjustment of confounding factors including age and sex, the associated factors(odds ratio) with overutilization perception were hypertension(1.25), arthritis(1.32), depression(1.66), visit of multi medical institutions(3.09), and those of the underutilization were female(1.34), disabled(1.27), no family support(1.49), living in medium and small city(1.48), experience of unabled-visit to medical institution(2.54), frequent visit-recommendation from physician (1.36). In conclusion, education and consult are needed for subjects to improve the reasonable decision of medical use, and the self-care ability to manage diseases and symptoms. We suggest reinforcing the alternative service in community instead of costly medical institution.
