With the recent trends of electronic commerce moving from B2C to B2B, Collaborative Product Commerce (CPC) is widely adopted as a part of B2B in the virtual collaborative environment. This paper proposes an integrated CPC framework supporting collaborative works between businesses by sharing product data and collaborative process between global enterprises and their customers, who are related to product life cycle, and integrating application systems in order to realize a true B2B electronic commerce. To integrate into a loosely coupled structure, various web service technologies such as XML, SOAP, WSDL and UDDI are utilized as its fundamentals and on that basis, a CPC integration framework is implemented through the Internet to support real-time operation providing interoperability among all the different applications operated on various platforms which have been developed using different languages and adopted by different companies.

This study is carried out to understand application type and change of learning space and to find out actual situation of management in open planned elementary schools. The twelve elementary schools were selected based on case studies and fundamental data of the agencies performing basic plan, the actual situation of management was studied by interviews of principals and teachers. By the results, open planned elementary schools have been notably reduced after the year of 2004 and corridor expending type was broadly chosen as a plane type for open space. It was also shown that learning space was transformed to the independent type integrating open space to the unit classroom in most part of twelve cases. In addition, whole sliding doors fixed in open classrooms by some Provincial Office of Education didn't need certain physical shut-offs, and it was considered as one of useful alternatives to manage open space.

This paper presents a geometric machining simulation algorithm to enhance the reliability and user-friendliness of a comprehensive computer aided process planning (CAPP) system by verifying generated NC data. In order to represent the complex machining geometry with high accuracy, the proposed algorithm is developed based on a boundary representative (B-rep) solid modelling kernel. Solid models are used to represent the part geometry. tool swept volume and material removal volume by Boolean unite and subtract operations. By integrating a machining simulation procedure into the CAPP system, the systematic analysis of the tool path can be implemented synthetically. To demonstrate and check the validity of suggested system, a simple example of simulation is represented and the result is discussed.

The most profound technologies are those that disappear. Silicon-based information technology, in contrast, is far from having become part of the environment. The idea of integrating computers seamlessly into the world at large runs counter to a number of present-day trends. Ubiquitous computing is not just aiming nomad multimedia. Rather, this computing environment lets us free to use computers without thinking and so to focus beyond them on new goals. In that context, Mom is such a fundamental membrane through which humans can interact with the environment. An embodied interaction paradigm, based on Mom, is investigated. Mom, space. sensing/perception, ubiquitous computing, and interactive technology are some of the key ideas to explore.

Collaborative product commerce (CPC) is a newly emerging technology to support inter-enterprise collaboration through the product life-cycle. From the IT point of view, CPC is software technology to integrate product, process and resources of different enterprises using Web technologies. In this paper, we introduce a CPC framework for integrating product information across enterprises, which being developed as a part of the CPC project by ETRI. The product metadata represented by XML schema, which is compatible with ISO STEP PDM Schema standard, is presented to semantically and schematically integrate distributed product information. The web services technologies are discussed to support the interoperability of application systems related to the product development, such as CAD and PDM, where most of these applications run in a distributed environment. Finally, we implement the frame-work to integrate distributed product information.

Since the response reduction effect on over 200-meter-tall resulting from the seismic isolation system is smaller in general than low-rise and mid-rise buildings, mid-story isolated buildings are considered to reduce the response in the upper part above the isolation story, however, in many cases, the acceleration response just below the isolation story is likely to be the largest. This paper presents the structural design schemes, the design of the main structural frames, and the constructions of a 230-meter-tall super high-rise building with mid-story isolation mechanism integrated in Roppongi, Tokyo. Moreover, this paper shows how the architectural and structural design for integrating a mid-story isolation system in a super high-rise building has been conducted and what solutions have been derived in this project. The realization of this building indicates new possibilities for mid-story isolation design for super high-rise buildings.

Most of dredged soil generating millions of tons per year is treated as a waste disposing in ocean or landfill except some part of recycling. The purpose of this study is to present the prerequisite for the use of dredged soil as a resource and analyse economic and environmental values of the recycling of dredged soil. The analysis of the economic and environmental value of recycling of dredged soil as a resource showed that several trillion won of budget can be saved in construction of disposal area or landfill and that loss of about 50 million tons of aggregates from deforestation can be restored by supplyment of dredged soil preserving a mountain as big as the Namsan(Mt.) every year. In order to utilize dredged soil in more diverse areas as high value of resource, the related domestic laws are needed to be readjusted integrating laws spreaded in different government departments and a special law is prepared and enacted.

Recent linguistic researches have brought into focus the relations between prosodic structures and syntactic, semantic or phonological structures. Most of them prove that prosodic information is available for understanding syntactic, semantic and discourse structures. But this result has not been integrated yet into recent Korean speech recognition or understanding systems. This study, as a part of integrating prosodic information into the speech recognition system, proposes an automatic detection technique of Korean accentual phrase boundaries by using one-stage DP, and the normalized pitch pattern. For making the normalized pitch pattern, this study proposes a method of modified normalization for Korean spoken language. For the experiment, this study employs 192 sentential speech data of 12 men's voice spoken in standard Korean, in which 720 accentual phrases are included, and 74.4% of the accentual phrase boundaries are correctly detected while 14.7% are the false detection rate.

웹 상에서의 다양한 멀티미디어 지원에 있어 이들 미디어들은 서로 분리되어 있으며 정교한 프로그래밍 작업 없이는 다른 요소들과 상호작용하지 못했다. 1998년 6월 발표된 SMIL1.0은 다양한 멀티미디어들간의 상호작용을 가능하게 하였다. 지금까지의 웹기반 멀티미디어 동기화를 위해서는 DHTML이나 Plug-In 등의 부가적인 방법이 사용되어 왔으나 본 논문에서는 SMIL Timing과 Style Sheet 언어를 이용하여 내용중심 마크업 언어에서의 구현이 용이한 멀티미디어 동기화 표현의 방법을 제시하고 그 특징을 살펴본다. 그리고 이를 실험하기 위하여 마크업 언어의 하나인 HTML에 제안된 방법을 적용하였으며 자바언어의 쓰레드 기술과 JMF 기술을 이용하여 시간적으로 미디어간의 동기화가 지원되는 브라우저를 설계 및 구현한다.

Car navigation system is one of the most important applications in telematics. A newest trend of car navigation system is using real video captured by camera equipped on the vehicle, because video can overcome the semantic gap between map and real world. In this paper, we suggest a visual car navigation system that visually represents navigation information or route guidance. It can improve drivers' understanding about real world by capturing real-time video and displaying navigation information overlaid on it. Main services of the visual car navigation system are graphical turn guidance and lane change guidance. We suggest the system architecture that implements the services by integrating conventional route finding and guidance, computer vision functions, and augmented reality display functions. What we designed as a core part of the system is visual navigation controller, which controls other modules and dynamically determines visual representation methods of navigation information according to a determination rule based on current location and driving circumstances. We briefly show the implementation of system.
