"The Act on Ubiquitous City Construction and etc." stipulates the regulations on the planning, construction and management of the u-City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet u-City requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new IT infrastructure construction process of the u-City in reality. It is also to supply with the each step framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the u-City IT infra construction guide line v1.0, purpose of the establishment of comprehensive IT infrastructure construction process.

Infrastructure asset management is a methodology for programming infrastructure capital investments and adjusting infrastructure service provision to fulfil established performance, considering the life-cycle perspective of infrastructure. In this study, the methodologies for infrastructure asset management system implemented in sewer management system, bridge management system, pavement and highway management system, and embankment dam management system are described with focus on the system in U.S. As the major methodology to support the decision-making for asset mangers to better allocate the limited funds to the area needing it the most. various demand forecasting methodologies used in wastewater, water, transportation, electricity, and construction are also introduced for their applicability towards infrastructure asset management.

The purpose of this study is to examine which factors are encouraging SMEs to participate in uTradeHub(focused on the uTrade search service) in terms of product characteristics and sourcing patterns. The three factors encouraging Trade e-Marketplaces are identified in this study. First, internal factors include the support of top management, mature of IT infrastructure. Second, external factors include the pressure of industry, industry competition, dependence of trading partners. Third perception factors are perceived Usefulness, perceived easy of use. The empirical analysis had the following results. First, it reveals that support of top management, mature of IT infrastructure, industry competition have significant influence upon uTrade Search Services. On the other hand, pressure of industry, dependence of trading partners, Perceived relative benefits are not significant variable of the participation in uTrade Search Services. Second, the factors affecting the participation in uTrade Search Services are differentiated in terms of product characteristics and sourcing patterns. And the support of top management, mature of IT infrastructure, Perceived relative benefits are emphasized very important factors affecting the participation of uTrade Search Services in SMEs. The industry competition is recognized as more important factor in horizontal market in which Spot sourcing just like Operating products is trading. On the other hands, the dependence of trading partners are significant factor in vertical market in which Systemic sourcing just like Manufacturing products is trading.

This paper discusses cases of infrastructure asset management in the U.S., Canada, and Australia and investigates infrastructure management in Korea in order to set the direction for the asset management improvement. The definitions of infrastructure asset management from various entities are introduced and implementation framework and organizational structures are described. The investigation on Korean public asset management practices finds the strong and weak points and defines the requirements and considerations to further improve the current practices. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

This study analyzes the development of technological infrastructure(TI) and technological infrastructure policy(TIP) to enhance the technological capabilities of small and mid-sized manufacturing enterprises(SMEs) in the U.S. and Korea in terms of the technological system(TS) concept, which is composed of technological infrastructure, industrial organization, and institutional infrastructure. In order to analyze the internal dynamics of the system, such as incentive mechanisms, the interaction among economic actors, and the policy implementation process, we compare the MEP(Manufacturing Extension Partnership) system of the U.S. and the Joong-Jin-Gong system of Korea. Among many similarities, contrasts, and insights from each country's effort to construct TI and TS, the main findings are as follows. (1) Both the MEP system and the Joong-Jin-Cong system are TI-led or government-led type TS. However, the nation-wide picture is different: in the U.S., most TSs including the MEP system., are classified as TI-led type; in Korea, many TI-assisted or private sector-led TSs have been developed since the early 1960s. (2) the MEP system, as a representative case of the U.S., is less stable than the Joong-Jin-Gong system of Korea in terms of financing and political cycle. (3) The MEP system is a more complex and cooperative network than the Joong-Jin-Gong system. NIST, as a critical mass, generates the system, bridges various institutions, and influences the development of the system by providing funding. (4) Regarding TI components, TSs in both countries focus on utilizing off-the-shelf technologies rather than advanced technologies. However, the direction of movement is different: in the U.S., TSs have come to emphasize existing technologies to counterbalance an innovation system that has been highly focused toward new technologies; in Korea, TSs have been moving from focusing on a higher diffusion rate of imported process technologies to stressing new technology development. (5) Personnel and staffing, embodying technological capability, is an important concern in both countries. But the human capital infrastructure of the U.S. system is more efficient and industry-oriented than that of the Korean system due to a more flexible labor market. (6) While the U.S. has a strong tradition of state and local autonomy in constructing TI and TS to fit SMEs's specific need, Korea has a centralized and bureaucratically-led policy implementation process.

유비쿼터스 도시(u-City)의 구축과 관련한 연구에 많은 관심을 집중되고 있지만, 여전히 많은 연구가 도시건설과 관련된 건축 측면과 기반 ICT 기술의 구현 측면으로 서로 개별적으로 다루어 지고 있다. u-City에는 다양한 서비스와 기술요소들이 혼재하기 때문에, 이러한 개별적인 접근은 효과적인 u-City의 구현을 어렵게 만드는 원인이 된다. 특히, u-City의 다양한 구성요소들이 지속적으로 변화하고 확장된다는 점에서 u-City 인프라에 대한 종합적인 연구가 더욱 다양한 측면에서 체계적으로 진행될 필요가 있다. 본 연구에서는 기존의 u-방재 참조 인프라에서 개념적으로 제시한 WBEM/CIM 표준과 그리드 모니터링 아키텍처(GMA)의 결합을 더욱 구체화하여 모델링 함으로써 WBEM/CIM 개발 도구를 활용하여 구현이 가능하도록 하였다. 기존의 u-City 인프라에 대한 연구가 여전히 추상적인 상태에 머물러 있는 현실에서, u-City 통합 인프라 모델을 구체화하여 구현에 더욱 다가선 모델을 제시했다는 점에서 향후 u-City 인프라에 대한 다른 연구에도 많은 참고가 될 수 있을 것이다.

유비쿼터스 컨버전스 산업의 가능성을 확인하기 위한 시험대로서 u-City에 대한 관심이 지속적으로 커져가고 있는 시점에서, u-City의 대표적인 서비스 및 응용 분야로서 u-방재에 대한 연구도 서서히 확대되어가고 있다. u-City의 다른 영역과 마찬가지로 u-방재 서비스의 원활한 제공을 위해서는 기존에 분산되어 운영되고 있는 다양한 u-City 서비스 및 하부 인프라가 종합적으로 연계될 수 있는 방법이 매우 중요하다. 본 연구에서는 분산자원관리 분야에서 널리 활용되고 있는 CIM/WBEM 표준과 대용량 모니터링 데이터의 취득 및 활용에 적절한 모델로 인정되고 있는 GMA를 결합하여 u-방재 서비스 및 모니터링 아키텍처의 설계에 적용하는 방안을 제시하고자 한다. 향후 u-City 서비스 인프라의 표준화 및 확장성에 대한 요구가 더욱 커져갈 것으로 예상된다는 점에서, 본 연구에서 제시하는 통합 인프라 모델은 기존에 구축되어 있는 분산자원들과 지속적으로 추가될 것으로 예상되는 신규 서비스들의 효과적인 통합 모델로써 활용될 수 있을 것이다.

Ubiquitous tourism information systems are more and more required to provide cultural contents comprising material heritage, performing art, folk tradition, handicraft or customs of everyday life, along with traditional tourist information about hotel facilities and infrastructure. This study attempts to investigate the effect of tourists' hotel preference attributes in terms of their satisfaction with ubiquitous tourism service. In so doing, 145 questionnaires were used to analyze the satisfaction of u-tourism service and the hotel preference attributes through the field survey. The questionnaires were collected from hotel employees who had experienced the ubiquitous tourism service. It is found that some of hotel-preference attributes positively influence u-tourism satisfaction but not all of them did. Service and differentiation attributes had an impact to u-tour and u-hotel function. And beverage attributes, to u-tour function, and convenience attributes, to u-hotel function. These findings mean that the hotel built u-tourism infrastructure gain a competitive advantage than the otherwise hotel.
