With the advent of new order of international competition, the technology Policy of Korea has been changed from vertical one which focuses on specific technologies or selective industries to a horizontal one which supports R&D activities on a neutral basis. TIP(Technology Infrastructure Policy) is WTO free in the sense that it is Indirect method of supporting technology development and properly defined as a part of government role by OECD. Technology infrastructure is embodied in human capital, and includes also elements of physical capital and knowledge. Hence it is more differentiated than, and distinguished from conventional infrastructure. It implies a need for carefully designed strategy with the recognition of those differences. As a fundamental element of innovation and technological development, technology infrastructure should become the main focus of industrial technology Policy.

The paper empirically examines relationships among information infrastructure, competitive advantage of information technology, and corporate performance of small and medium manufacturing firms. Effects of competitive advantage of information technology on the linkage between information infrastructure and corporate performance are investigated. The fact that SME's (Small and Mediem-sized Enterprises) are having difficulties in building their own information infrastructure due to the limitation of capital investment, technology, and manpower is the main motive for the study. Research results confirm that information technology provides several traits of strategic advantages such as efficiency, threat, functionality, preemptiveness, and synergy and significantly contributes to corporate performance. But linkage between information infrastructure and competitive advantage of information technology is proved to be weak and this result suggests that systematic and effective information strategy or planning is required to deliver expected advantages of information technology from information infrastructure investments. Also control effect of competitive advantage of information technology on information infrastructure-corporate performance linkage is not strongly recognized.

The developments and implementations of the structural health monitoring (SHM) system for large infrastructures have been gradually recognized by researchers, engineers and administrative authorities in the last decades. This paper summarizes an updated review on innovations and applications in SHM for infrastructures carried out by researchers at Dalian University of Technology. Invented sensors and data acquisition system are firstly briefly described. And then, some proposed theories and methods including the sensing technology, sensor placement method, signal processing and data fusion, system identification and damage detection are discussed in details. Following those, the activities on the standardization of SHM and several case applications on specific types of structure are reviewed. Finally, existing problems and promising research efforts in the field of SHM are given.

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.

지하 30m 암반에 건설된 통신구 터널의 안전성을 검토하기 위하여 콘크리트 라이닝 두께를 지중레이다(Ground Penetrating Radar)와 충격반향기법(Impact-Echo Method)으로 추정하였다. 지중레이다에 의한 콘크리트 라이닝 단면의 연속적인 화상으로부터 라이닝 두께의 상대적인 변화를 파악하였으며, 라이닝 두께가 얇은 구간은 충격반향 기법에 의해 일정 간격으로 두께를 추정하였다. 터널 천장의 라이닝 두께는 31.85cm, 좌측 및 우측 측벽부의 라이닝 두께는 각각 32.45cm. 32.97cm로서 설계 값인 30cm와 비교적 잘 일치하는 것으로 파악되었다. 지중레이다와 충격반향기법을 조합한 본 방법은 터널 라이닝 콘크리트 두께를 추정하는데 있어서 매우 효율적이고 신뢰성 있는 방법으로 분석되었다.

Delay, cost overrun and inferior quality in public works are common in Nepal and Cambodia. Almost 90 percent of the civil construction engineers working in the industry were one-degree graduates without appropriate training. The civil engineering education had provided elemental engineering knowledge to the graduates however integrated engineering and management knowledge and skill are essential for efficient infrastructure development. ODA in developing countries had been concentrated in hard infrastructure development without improving the quality of higher education. Integrating ODA to engineering education system would help develop qualified technical manpower and appropriate technology domestically, and improve the efficiency in infrastructure development in developing countries.

This paper describes the backgrounds, motivations and recent history of structural health monitoring (SHM) developments to various types of engineering structures. Extensive applications of SHM technologies in bridges, high-rise buildings, sport avenues, offshore platforms, underground structures, dams, etc. in mainland China are summarily categorized and listed in tables. Sensors used in implementations, their deployment, damage identification strategies if applicable, preliminary monitoring achievements and experience are presented in the lists. Finally, existing problems and promising research efforts in civil SHM are discussed, highlighting challenges and future trends.

As the value and role of intellectual property increases in our knowledge-based economy, countries around the world have exerted various efforts to secure, utilize, and protect their intellectual property. The present study diagnoses the level of IP infrastructure of major OECD countries and analyzes their characteristics and impact. According to the diagnosis, the US, Switzerland, and Germany form a leading group followed by the mid-level countries of Korea, Ireland, Australia, and France, with Spain and Italy in the bottom group. In contrast to Korea's competitiveness in S&T and R&D infrastructures, its competitiveness in IP infrastructure is lower than the OECD average. This is thought to be due to Korea's IP infrastructure being hastily formed under the influence of international pressures rather than having been gradually built up by internal needs. A TFP analysis of the impact of IP infrastructure on economic growth shows IP infrastructure positively influences economic growth. Though this analysis is limited due to inability to secure sufficient data and indicators, it is a useful guide for understanding the nature and key characteristics of IP infrastructure.

The advanced infrastructure for accelerating the development of personal robots is presented. Based on this structure, effective ways for integrating the various commercial components and interfacing among them are studied. The infrastructure includes the technology such as modularization based on independent processing and standardization open to other developers. The infrastructure supports not only that each hardware component of a personal robot can be easily attached to and detached from the whole system mechanically but also that each software of the components can be functionally distributed. As a result, we developed the fully modularized personal robots mechanically, and a virtual machine for the control of these robots. In this paper the proposed infrastructure and its implementations are described.

최근 사이언스 컴퓨팅 분야에서 대용량 데이터가 발생하고 있고 컴퓨팅 자원들의 수요도 급증하고 있다. 이로 인해 클라우드 컴퓨팅 기술의 필요성이 중요시되고 있고 전 세계적으로 급속히 발전하고 있다. 천문 연구 분야에서 관측기기의 발전으로 대용량의 천문 데이터가 생산되고 있다. 이를 처리하기 위하여 다양한 클라우드 컴퓨팅 기술을 이용한 데이터 분석 환경이 요구되고 있다. 이러한 환경을 구축하기 위해서는 가상 인프라 자원을 효율적으로 관리할 수 있어야 한다. 현재 가상 인프라 자원을 관리하기 위해 오픈 소스를 개발하는 프로젝트들이 활발히 진행되고 있다. 본 논문에서는 오픈 소스인 Eucalyptus와 OpenNebula의 기능적인 측면을 크게 10가지로 분류하여 장단점을 비교 분석하였고 OpenNebula의 세 가지 특징인 중앙 집중화된 구조, live migration과 suspend/resume 기능, 커스터마이징 기능이 대용량 천문 응용 수행을 위한 환경을 구축하는데 반드시 필요하기 때문에 OpenNebula를 채택하였다. OpenNebula를 사용해 구축한 사이언스 클라우드 테스트베드는 NFS 서버의 별도 구성을 통한 성능 개선, 하이브리드 클라우드 컴퓨팅 환경 구축, B클래스 사설 네트워크 구성, GUI 기반 사이언스 클라우드 테스트베드 관리 및 모니터링 기능의 4가지 특징을 가지고 있다. 앞으로도 천문 연구자들에게 안정적인 서비스를 제공하기 위하여 관련 연구를 계속할 것이다.
