u-Healthcare 활성화의 필요성이 꾸준히 제시되어 왔으나, 아직까지 이해자들의 공감대를 이끌어 낼 수 있는 개념정립 및 분류체계가 미비한 실정이다. 새로운 서비스 영역인 u-Healthcare 분야 산업 발전을 위해서는 정책적 전략과 제도적 정비 등의 기반조성이 필요하며, 이에 앞서 명확한 개념 정의와 영역 범주화의 필요성이 제기되고 있다. 본 연구에서는 ubiquitous computing 속성에 대한 이해를 통해 u-Health 환경과 u-Healthcare를 정의하며, 보건의료적 접근에 의한 분류를 통해 보건의료서비스에의 적용가능 분야를 제시하고자 한다.

Ubiquitous is an information communication environment which peoples could connect on network without being conscious of the network and computer condition at anytime and anywhere. Presently, advanced technology, digital cities and eco-friendly cities using Ubiquitous technology are being focused through out the world. As recent information industry and communication technology have developed remarkably, studies on intelligent structures and structural maintenance methods by combining a general idea of connecting all objects on network by interpolating computers which is called Ubiquitous Computing, and USN(Ubiquitous Sensor Network) are being attempted. In this paper, a basic experiment on penetration of RF(Radio Frequency) sensor nodes using an experimental sample setting concrete and reinforcing bar as variables is studied to estimate the possibility of applying wireless sensor networks in structures. The spring of reinforcing bars, concrete thickness, intensity of radio frequency were set up as variables, transmitting and receiving distance were checked vertically and horizontally. Moreover, Spectrum Analyzer was used for checking the magnitude of the frequency used in order to measure the reduction of radio wave exactly. The radio wave reduction was numerically analyzed, and the influence of the wavelength was analysed as well. As a result, the penetration depth in concrete without reinforcing bars was 45cm, and in reinforced concretes which reinforcing bars placed at spacing of 5cm and 15cm, the penetration depth were 37cm and 45cm each. No influence on radio wave penetration depth were found when the spacing of reinforcing bars in the reinforced concrete structures becomes over 15cm.

조금 길게는 30여 년 전 인터넷이 탄생할 때는 아무도 오늘날과 같은 인터넷 세상을 상상하지도 못했을 것이며, 그리고 짧게는 불과 5년전 만 하더라도 지금과 같이 대부분의 사람들이 휴대 단말기를 사용하여 언제 어디서나 통화할 수 있게 되리라는 것을 거의 예측하지 못했을 것이다. 현재의 기술 추세를 감안하면 앞으로 5년, 10년 후에는 유비쿼터스(ubiquitous) 컴퓨팅 환경에 맞는 입는 컴퓨터가 우리들의 실생활에 활용될 것이다.(중략)

Construction automation based on information and communication technology(ICT) has been studied for improving productivity in the construction industry. This study investigates domestic research trends in ICT-based construction automation using text mining techniques. The results show that 'Technology to collect and analyze project progress(26%)' and 'Technology to analyze and apply the automation element of construction machinery(28%)' are the major research area. The word of 'construction information' is showed as important keywords in the area of 'Technology to collect and analyze project progress', and researches focusing on resource management, site management, information management, and real-time information monitoring have been mainly conducted. The word of 'ubiquitous' is shown as important keywords in the area of 'Technology to analyze and apply the automation element of construction machinery', and researches focusing on ubiquitous information management, ubiquitous site management, and measurement system have been mainly conducted.

This paper analyzed articles of u-City Construction Law, which has been enacted on 29th of September last year, and evaluated their appropriateness and other laws associated with u-city services for better provision of u-cities and u-city services. The enacted law established the concept of u-city in Korea and provided relating industries with construction procedures, technology developments, and standards. These efforts have substantial implications as the first stepping stone, but also raised several problems. Hence, this paper suggested that the u-City Construction Law should be amended as follows. First, The minimum size of u-cities, that is required by the law, should be decreased. Second, various kinds of incentives should be provided to the u-city project companies. Third, new organizations such as u-City commission and National or Regional Control and Management Center will be necessary. Fourth, technology standards and inter-operability among cities should be provided in the areas of the control and management centers. And Finally, more measures of and focuses on project financing issues should be made.

This research analyzes the use intention of the ubiquitous service based on the technology acceptance model (TAM). This study investigates the characteristics of the ubiquitous service like the ubiquity, personality, connectivity, and location. The major results of this study are as follows. The ubiquity, connectivity, and location had positive influences on the perceived usefulness and perceived ease of use. And, the personality had the positive influence of the perceived ease of use. The perceived usefulness and perceived ease of use had the positive effect to an attitude, and the attitude had the positive effect to an use intention.

Recently, a high strength concrete(HSC) in excess of 80 MPa is popular to use in the domestic construction field. But there is no design standard of high strength concrete. It is reason why a study about structural behaviors of thin walls is required. In this paper, the accurate Finite Element Method as a virtual test is suggested considering material properties, which are concrete and steel, and the experimental fractural model suggested by Kupfer. It is conducted the comparison evaluation of the ultimate failure loads, lateral-displacements and crack propagation patterns between the results of experimental approach, which were carried on Saheb's test for normal strength concrete and Lee's test for high strength concrete. Therefore it is suggested to use the accurate virtual simulation test method and Ubiquitous Sensor Network(USN) by Finite Element Method for Internet of Things(IoT).
