BOM(Bill of Materials) is a list or description of raw materials, parts and assemblies that define a product. Although it is very important for maintenance information system of urban transit, it has problems that the size of database, inaccuracy and the flexibility which is measured as the number of updating records in accordance with added new product or engineering change. To solve these, we divide BOM to a master BOM and various function BOM constructed from the master BOM. That is the component based BOM management system, which is mutually independent and integrated efficiently using component technology. Consequently, after defining the component based master BOM, it is easy to manage the data structure, even restruct, in case there is a need for change of environment or data.

This study examines whether expenditures in information technology (IT) are associated with increases in Tobin's q ratios, a measure of management performance, in the banking industry. The association between IT expenditures and Tobin's q ratios is different, depending upon the banks' size (national vs regional) and strategic orientation (wholesale vs retail), in the Korean commercial banks for the period studied 1990-1996, For national commercial banks which have more clients and electronic banking systems than regional banks, IT expenditures appear to increase Tobin's q ratios. This may indicate that IT is linked to the ability to achieve economies of scale or network effects when large banks use IT as a strategic tool. The association between IT expenditures and management performance measures is also positive and statistically significant for retail-oriented banks. This research makes two important practical contributions with respect to financial reform. First, the evidence suggested that Korean commercial banks need to apply IT strategy in conjunction with restructuring strategy to be a super-bank and, hence, reap substantial competitive advantage from IT applications. Second, since the government recently encouraged commercial banks to increase credit loans as a means of financial reform, most banks tend to focus on retail banking. IT used in the retail banking sector contributes to improve management performance as the evidence suggested.

This study is aimed to improve future-oriented curriculum by investigating the satisfaction of students from beauty art-related departments on their curriculum and major courses and proposing their basic direction and improvement plan. For this, a survey was conducted against students from beauty art-related departments in Busan (5 junior colleges and 1 four-year university). The following results were obtained: First, according to a correlation analysis on major questionnaire items on the curriculum in beauty art-related departments, statistical significance was observed in 'curriculum development', 'facility and administrative & financial supports', 'instructor/teacher activities', 'educational evaluation activities', 'academia-industry cooperation activities' and 'output evaluation'. In terms of educational satisfaction, statistical significance was observed in all positive relations. Second, according to regression analysis on the evaluation of curriculum output factors in beauty art-related departments, output factor levels were high as 'academia-industry cooperation activities', 'age', 'teacher/instructor activities', curriculum requirement analysis' and 'curriculum development' were high. In overall, relatively good results (69.0%) were observed. A further study needs to be performed for improvement of satisfaction of students majoring in beauty art on their curriculum in educating students from beauty art-related departments by applying their educational evaluation to optimum standards.

Smartwork is future-oriented work-environment to bring swift business transaction and convenient for users. In domestic and foreign various countries, It's already prompting introduction of smartwork. Users process work to access frequently from the outside in smartwork that's a similar client/server environment to existing Cloud Computing environment. Necessary of user authentication is increasing to be solvable to security vulnerability because there is possibility that malware flows in and leaks company's confidential information by unauthorized users especially in smartwork environment. Therefore we propose User Authentication scheme based face recognition is applicable to smartwork environment to analyze established User Authentication scheme. environment.

With the understandings on users' needs and behaviors of university institutional repositories, the purpose of this study is to investigate the user behaviors and to provide some suggestions to improve the university institutional repository. To achieve the purpose of this study, a questionnaires survey was conducted with users in three university institutional repositories including KOSAS, S-Space and DSpace@INHA. Based on the results of the survey analyses, possible improvement areas and suggestions were made such as users' recognition, access point, searching environment, and utilization of university institutional repository.

As scholarly information environment rapidly changes, library consortia for electronic journal licensing come to require strategies to better address service needs of member institutions as well as to take parts in more progressive initiatives. This study aims to develop a more future-oriented and progressive business model for electronic journal licensing consortia. The model is based on three pillars: strategies for responding to immediate needs; long-term strategies for leading change; and organizational infrastructure.

As interactivity is becoming one of the key success factors in today's digital communication environment, increasing emphasis is being placed on technologies for user-oriented emotion expression. We aim for development of enabling technologies for creation of emotional characters who can express personalized emotions in real-time. In this paper, we conduct a survey on domestic and international researches and case studies for emotional characters with a focus on facial expression. The survey result is believed to have its meaning as a guideline for future research direction.

The temperature dependence of electrical conductivities and thermoelectric power of $I_2$-doped poly(1,4-penylene vinylene-co-2,5-dimethoxy-1,4-phenylene vinylene)s [poly(PV-co-DMPV)] and poly(1,4-phenylene vinylene-co-2,5-thienylene vinylene)s [poly(PV-co-TV)] were studied. The former copolymers were also doped with $FeCl_3$. All the samples used were in thin film forms. The temperature dependence of electrical conductivity implies that the variable range hopping conduction mechanism applises to these systems. The activation energy for the electrical conduction in dimethoxy-phenylene vinylene (DMPV) copolymers ranged from about 7 to 30 meV depending on the polymer composition and the nature of the dopant. It was significantly higher for $I_2$-doped thienylene vinylene (TV) copolymers, namely 90-200 meV. The values of the room temperature thermoelectric power were $30-70{\mu}V/K$ for DMPV copolymer and $100-800{\mu}V/K$ for TV copolymers. Anisotropy in the electrical conductivities was also studied for oriented films obtained by uniaxial stretching of the precursor polymer films.

Based on the rapid development of IT technology and deployment of the Internet through high speed networks, network environments have been changed from office oriented environment based on business industries and public institution even to the interconnection to digital electronics in the home network. Home network based applications are very diverse and the remote monitoring and control areas have been studied. In this paper, we present the design and implementation of real time remote video monitoring system which provide the moving pictures on the web page through the Internet using JMFI. In addition, we present the design of remote light control system based on Zigbee.
