This paper deals with the design process of the footbridge over the branch between Singil and Yoido. For the design of a resonable and beautiful footbridge, it is required to consider technical methods and artistic geometry. The design approach to this footbridge is related with both the field of science and art, therefore from starting the process is made in cooperation with engineers and architects. It results in not only reasonable but economical structural master piece to close the gap between a technology-oriented tendency and a artistic inclination toward structural design.

This paper describes a prototype expert system to aid operation in rod consolidation process. The knowledgebase is composed of three database groups and 60 rules with production, and object oriented techniques that correlates database groups. The expert system is designed to track the transitions of nuclear materials through the operation areas of the rod consolidation process, to diagnose current status in any operating conditions, normal and off-normal, and to advise operators to properly recover off-normality. The expert system can give efficient management of nuclear material accountability and process operation in the rod consolidation.

Animals possess a highly sophisticated mechanism of storing energy in adipose tissue inside their bodies. However, in humans it has been clarified that adipocyte (fat cell), which composes the body fat (adipose) tissues, development and the extent of subsequent fat accumulation are closely associated with the occurrence and advancement of various common diseases (e.g., type-2 diabetes, coronary artery disease, and hypertension) resulting from obesity. Recent exciting progress in clinical and biochemical studies of adipocytes has rapidly clarified the functions of adipocytes and adipose tissue. Interesting findings are the function of white adipocytes as "secreting cells" and the molecular mechanism undelying adipocyte differentiation at the transcriptional level in relation to nuclear receptors. Consequently, the adipose tissue is being targeted for the prevention or treatment of many common diseases. In this review, I will focus on recent information on characteristics of adipocytes and the relationship between obesity and common obesity-related diseases. diseases.

The paper presents the EBORD (Extended Benchmark for Object-Relational Databases) benchmark, which is an extension of the BORD benchmark for object-relational databases. The EBORD benchmark is developed to evaluate the database common functions that should be supported in modern database systems. Besides the 36 test queries already defined in the BORD benchmark, totally 22 test queries in five categories are newly defined in order to measure the index-relevant performance issues and database import capabilities. The EBORD benchmark also features scalability, use of a synthesized database, and a query-oriented evaluation. In order to show the feasibility of the proposed benchmark, we implement it with two commercial database systems. The experimental results and analyses are also reported.

In this paper, we design and implement a XML management system based on OODBMS that supports structured information retrieval of XML documents. We also propose an object oriented modeling to store and fetch XML documents, to manage image data, and to support versioning for the XML document management system(XMS). The XMS consists of a repository manager that maintains the interfaces for external application programs, a XML instance storage manager that stores XML documents in the database, a XML instance manager that fetches XML documents stored in the database, a XML index manager that creates index for the structure information and the contents of documents, and a query processor that processes various queries.

The demands on hospital facilities are increasing because of the higher living standard and the advanced medical technology. The user-oriented concept of LDR/P(Labor, Delivery, Recovery/Postpartum), which reflects the current demand, were proposed in the delivery center and was recently introduced to Korea. This study aims to represent the data base for architectural planning and the design of the LDR/P in delivery center reflecting the domestic situation. The case study was performed to investigate the change of space and to consider the architectural characteristics of LDR system in delivery center.

With the development of industrial technology an amount of information has sharply increased and an information-oriented society had come. This information environment changed the function of library. Today's public library not only save and record the information but also encourages residents to use information and culture activities such as lifelong education. As the library plays a variety role, it has become an multiplex space. Added new function, various space has formed and each space requires their own interior images that fits it's character. Here this study is to research new changed library's characteristic in interior image through five library's on-the-spot survey.

Web services are the core technology for changing from traditional web to SOA(Service Oriented Architecture) based Web. It is time to adapt the web services to Mobile Devices such as PDA, smart phone and so on. Specially Korea has an efficient mobile environments that is based on CDMA. That is suitable for evaluating the web services in mobile environments. This paper explains a framework of mobile web services based on intermediaries. Intermediaries support various enhanced functionality for mobile environments.

Digital Multimedia Broadcasting (DMB) and Internet Protocol Television (IPTV) are now in commercial service, tearing down the traditional boundaries between the telecommunications and broadcasting sectors. These latest developments also hold important implications for research projects in related areas. Both telecommunications and broadcasting being fields with a strong service orientation, market demand should be the primary consideration when selecting research and development (R&D) projects in these areas. This study presents a process for selecting converged telecommunications-broadcasting technology development projects from a demand-oriented perspective, using criteria that are based on projected future demand characteristics. Aimed at increasing the efficiency of the R&D project selection process in telecommunications and broadcasting convergence, this study can point out new directions in R&D management in this field.

본 논문에서는 위치기반 서비스에서 도로 네트워크 상을 움직이는 객체들의 현재 위치를 효율적으로 갱신하는 색인기법을 제안한다. 효율적인 시공간 질의 처리를 위하여 도로를 적절하게 분할하여 색인하게 된다. 기존의 도로 분할 방식은 연결정보를 포함하지 않기 때문에 객체가 현재의 도로 영역을 벗어났을 때 색인구조를 처음부터 검색해야 하는 단점이 있다. 제안하는 기법은 도로를 분할할 때 교차점을 포함하도록 분할하여 연결 정보가 유지되도록 한다. 이로 인해 제안하는 알고리즘은 객체가 색인된 현재의 도로 영역을 벗어났을 때 연결 정보와 NN(Nearest Neighbor) 검색 기법을 이용하여 벗어난 도로를 바로 찾아갈 수 있으므로 향상된 갱신 성능을 보인다.
