The emergence of ubiquitous autonomic computing and network environment will change the service architecture information system which will be a new application area in SCM/logistics systems. In this study we surveyed the technical trend map of ubiquitous and its application in SCM/logistics support system design. We described the evolutional model of ubiquitous computing community for SCM/logistics system. It is consisted of three view points; self-growing, autonomic, and context-aware, which will allow the decision makers to be benefited from web and mobile technology and are useful for proactive SCM/logistics support system. Finally, we suggested a cooperative research planning for the development ubiquitous system between the government research center, university, and industry research activities.

Construction CALS has contributed much to the improvement of construction management. Recently, the ubiquitous technology brings another opportunities for expanding tile business horizon in construction. The government policies to upgrade the information technologies in Korean offer an environment in which practical application of ubiquitous becomes more practical. To maintain the level of competitiveness, construction companies need to pay attention to the chance of ubiquitous technologies. This paper introduces the research movement in the construction industry in an attempt to find out the feasibility of ubiquitous technologies such as RFID, USN, etc. The construction process, which is executed in the natural environment, will benefit from the state-of-are information technologies in terms of improved communication interface.

We build middleware architecture with J2EE and LiveGraph to process different ubiquitous healthcare application's data and process that data into useful information, which can play a most important role in decision making in ubiquitous Healthcare System. Application developers mostly rely on third party middleware, tools and libraries (i.e., webservers, distributed middleware such as CORBA, etc.) to respond the emerging trends of their target domain. With this middleware we tried to enhance the efficiency of application by decrease their memory uses, data processing and decision making on another web module which is independent of each application. For middleware system, we proposed an algorithm by which we can find some important conclusion about different health status likewise ECG, Accelerometer. etc., which can be used in various data processing and determine the current health status. In this paper we also analyze some different low level and high level middleware technology which were used to build different kind middleware likewise CAMUS, MiLAN and try to find the best solution in the form of middleware for Ubiquitous Healthcare Information System.

유비쿼터스 사회의 도래에 따라 교육의 패러다임도 변화되고 있다. 유비쿼터스 환경의 u-러닝에서는 휴대폰, PDA, PMP, UMPC, TPC 등의 모바일 기기가 중요한 학습도구가 될 것이다. 특히, 유비쿼터스 사회의 핵심 기술인 RFID를 모바일 기기와 함께 교수-학습에 활용한다면 의미있는 학습이 되기에 충분하다. 본 연구에서는 RFID를 교수-학습에 적용하기 위한 방안으로 RFID-card, RFID-book, RFID-label, RFID-test의 네 가지를 제시하였으며, RFID-label의 방법을 실제 교수-학습에 적용하고 그 가능성과 효과성을 탐색하였다. 그 결과 RFID의 교수-학습 적용에 대한 긍정적인 효과와 가능성을 얻었다. 하지만 RFID를 교수-학습에 적용함에 있어서 기술적으로 부족한 점이 나타났으며, RFID의 교수-학습 적용을 위한 모델의 지속적인 연구의 필요성이 제기되었다.

Ubiquitous technology(UT)의 발전과 더불어 특성 산업에 가시적인 적용 성과가 나타남으로써, 전통적인 제조업에서도 ubiquitous 환경 구현 및 제조기술(MT: Manufacturing Technology)과의 융합을 통한 제조혁신의 필요성이 대두되고 있다. 따라서, 본 연구에서는 ubiquitous factory 구현을 위한 체계적인 서비스 개발을 위해서, factory에 적용할 수 있는 특정 서비스 platform 개발을 목적으로 한다. 이를 위해, 서비스 개발 platform과 관련된 연구와 ubiquitous 서비스 개발 방법론 등을 분석하여 factory 현장에 바로 적용할 수 있는 platform을 개발하였다. 개발된 platform을 검증하기 위해 사례분석을 통해 연관분석을 실시함으로써 본 연구의 타당성을 검토하였다. 본 연구에서 개발된 platform은 ubiquitous factory를 구현하는데 활용될 예정이며, 향후 적용을 통한 개선사항을 도출하여 제조혁신을 위한 방법론으로 정립할 예정이다.

In ubiquitous computing environments, users want to receive the robot services regardless of various physical status or devices such as time, place, various sensors, and high-performance servers. Thus, the ubiquitous service robots have to provide users with automated services according to situational information that they properly recognize. Beyond these problems, robot software has to establish a foundation to support the functions with the network infrastructure that are not able to be solved by a single independent resource. On the basis of a robot middleware that is capable of minimizing dependencies among hierarchy structures, the robot software also has to provide execution environment to control the flow of robot application services. In this paper, we propose a layered architecture to provide users with automated services through ubiquitous robots. The proposed architecture is based on CAWL (Context-Aware Workflow Language) and RSEL (Robot Services Execution Language). CAWL easily represents the flow of robot services from user application service levels, and RSEL is able to support the composition and reusability of robot services through abstraction of robot device services. In our experiments, we applied the proposed architecture to an example of "booth guide robot service".

The object of this paper is to describe the ubiquitous computing technologies for ship, which is produced and assembled by many steel blocks. It includes the testing of a 2.4GHz wireless communications platforms and radio-frequency identification technology with the blocks disturbing the wireless communication. The power line communication that is established in a ship already is also experimented for some data transfer. Also, possible application areas of the ubiquitous computing technology to ships are discussed. At last, the test bed copied from an actual vessel was installed and data acquisition tests were established using wire and wireless communication. In this paper, we implemented some ubiquitous computing technologies in the test bed simulating a ship environment and investigated the basic characteristics of ubiquitous computing technologies.

유비쿼터스 도시는 도시건설산업과 유비쿼터스 정보기술의 융합에 의해 이루어진다. 도시건설산업은 도시의 물리적 공간을 건설하는 분야로 점점 공용화, 통합화, 융합화 될 것이다. 지하시설물은 공동구를 활용하여 공용화하고, 지상시설물은 통합화가 가능한 시설들부터 통합화한 후 센서통신망이 발전하면 융합화시켜 지능화시킨다. 정보기술은 전산화를 지나 정보화를 이루었고, 유비쿼터스 정보화로 발전되고 있다. 이 논문은 유비쿼터스도시의 건설등에 관한 법률이 시행됨에 따라 도시공간과 유비쿼터스 기술의 융합화 방향을 설정하기 위한 논문이다.

Ubiquitous computing is an emerging technic for various areas such as public, private (individual), military, industrial, medical sectors. The applications of ubiquitous computing are expected to be prevailed from home to office. Unfortunately, it is not effective to apply existing system/software development methodologies into this emerging ubiquitous computing applications. In this paper, MBASE (Model-Based system Architecting and Software Engineering) is applied as a development method of ubiquitous computing applications. The advantage of MBASE is to identify mismatches of product, process, property, and success models and resolve them in developing the ubiquitous computing applications. A SmartView, a ubiquitous computing application, is presented as a case study o f MBASE.
