In this paper, we have studied about the ubiquitous service map for the effective u-City service providing. Through the research, we are going to propose the fact that it can be implemented ubiquitous services according to city characteristics. The proposed research could make it possible to be an intelligent decision making system by city characteristics. Also, nation, local government, companies can be assigned their appropriate load according to the proposed system for the effective u-City services.

The ubiquitous environment is to support people in their everyday life in an inconspicuous and unobtrusive way. This environment requires information such as the person, his/her preferences, and habits which is available in the ubiquitous system. In this paper, we propose the context aware system that can provide the tailored information service for user in ubiquitous computing environment. Our system architecture is divided into 4 domain models such as context awareness, presentation, interface and inference domain. Each domain model can perform some predefined tasks independently. And we suggest the hybrid algorithm combined with fuzzy and Bayesian method in order to reason what is the suitable information for user. We show the possibility for the real application through applying the system to the TGA (Tour Guide Assistant) for Kyoungju historical site.

표준 웹 환경의 확산으로 HTML5를 기반으로 웹 저작을 지원하는 많은 WYSIWYG HTML5 저작도구들이 등장하고 있다. 그러나 대부분의 WYSIWYG HTML5 저작도구는 컴포넌트 이벤트에 대한 기본적인 함수 작성 기능만 제공 할 뿐 컴포넌트 제어를 위한 코드 어시스트 기능을 제공하지 않고 있다. 본 논문에서는 이클립스 JSDT(JavaScript Development Tools) 코드 어시스트개념에 대해 기술하고, 이를 기반으로 WYSIWYG HTML5 저작도구에서 제공하는 컴포넌트 제어를 위해 코드 어시스트 가능을 구현하였다. 이로 인하여 WYSIWYG HTML5 저작도구에서 제공하는 컴포넌트에 대한 사용자들의 접근성과 개발 생산성 증대가 기대된다.

HTML5의 표준 웹 환경 확산과 스마트폰 점유율 상승과 더불어 다양한 디바이스에서도 동일한 화면을 제공하는 반응형 웹이 부각되고 있다. 반응형 웹을 적용하는 사이트가 지속적으로 증가하고 있으며, 특정 분야에 치중되지 않고 다양한 분야에서 활용되고 있다. 본 논문에서는 반응형 웹 디자인을 위한 주요 기법들에 대해 기술하고, 이를 기반으로 WYSIWYG HTML5 저작도구에서 컨텐츠별 페이지 레이아웃 설계 없이 태블릿과 모바일 페이지를 자동으로 생성할 수 있는 사용자 직관적인 반응형 레이아웃을 설계하였다.

데스크탑, 태블릿, 스마트폰등 다양한 인터넷 접근방법과 크롬, 사파리, 파이어폭스등 다양한 브라우저가 사용됨에 따라 이런 여러 가지 인터넷 환경에 대응하기 위해 W3C에서는 HTML5를 권고하고 있으며 이에 따른 표준화를 진행하고 있다. 전 세계적으로 HTML5로의 전환을 빠르게 확산시키려는 움직임을 보이고 있으나 선도 기업을 제외한 공공기관 및 민간 기업에서는 전문 인력 부족, 학습 비용 투자 등 여러 가지 문제로 인해 전환속도가 미흡한 실정이다. 본 논문에서는 HTML5에 대한 국내외 표준화 및 시장현황에 대해 기술하고, 이를 기반으로 WYSIWYG HTML5 저작도구를 설계하였다.

Nowadays, the importance of safety monitoring for facilities is increasing. Therefore, the introduction of ubiquitous technology to replace the existing manually-operated methods is required. In this study, a web-based GIS system that provides monitoring information of bridges in real-time for the application of a bridge management system through the use of ubiquitous technology is constructed. Particular attention is given to the effective interconnection of bridge monitoring information and bridge management system and, through a ubiquitous environment, how to connect this with the UFID and the GIS-based bridge management system (BMS) operated by the Ministry of Construction and Transportation. In addition, data expression methods are also suggested that state the detailed locations and attributes of structures in bridge management by using GIS.

The ubiquitous computing environment could provide better service to users by adapting to changing contexts. In this paper, we developed a context adaptation system, which enables an ubiquitous program to adapt to different contexts, following its adaptation rules. Using this system, programmers can develop ubiquitous programs suitable for changing contexts, by describing the context adaptation policy. The context adaptation engine of this system fits the ubiquitous program to the current context based on the context adaptation rules. This system was implemented using JCAF, context-aware programing framework based on java. A simulator is also provided to simulate ubiquitous programs by changing contexts.

System management application system is one of the most interesting fields in Ubiquitous Sensor Networks. It conforms to the property of Ubiquitous Sensor Networks very well, and it is the closest application for commercial use. We have two kinds of system management technology, such as the one which is accessed by web browser at anytime, anywhere and another one which is for local accessed system. In this paper, our purpose is implementation of system management application system which provides Mesh Sensor Networks topology with IP based agent platform and system management server. Furthermore we introduce the functions used for our recent implementation and propose several future issues about system management application system.

Ubiquitous information technology creates new space connected to electronic and physical space and makes new life pattern come true. Although it is expected that ubiquitous technology will lead significant changes on various life fields, relevant studies on its market needs, customer needs in social and cultural context and its necessity at organizational level have been passively carried out. What is worse, IT technology application scheme in railway field has not fully established since railway field's technology development is mainly focused on hardware compared with road and air traffic. In order to apply ubiquitous technology to railway field, therefore, it is required to identify ubiquitous technology functions which applicable to railway field and to establish ubiquitous rail system implementation scheme for end users. In this paper, we suggested implementation scheme for u-Rail which sorts railway industry by its components in order to implement service centered ubiquitous technology to each railway industry field.

The ubiquitous computing environment is widely expanded in almost all industries such as transportation. physical distribution, manufacturing, communication, tourist industry, financial business, and so on. But the construction industry is not well applied yet. Thus this study investigate the ubiquitous computing environment and propose a way for applying this technology to the construction industry. To achieve this aim, this study consider about a instrumentation management of retaining wall system in earthmoving operations, and suggest the ubiquitous system configuration to measure the variance of retaining wall. Through this system, the efficiency of the instrumentation management of retaining wall will be improved.
