MPEG-4 provides high compression rate and uses object-oriented method to describe components of its structure, which has currently risen as the core technique in multimedia service fields. Our research objective is to provide object manager to MPEG-4 system in order that effective multimedia service could be available by supporting powerful interaction and adapting to various networks and terminals. Through the object manger, priorities are given to objects of a scene tree and the objects having higher priorities are first rendered according to the terminal capability. It also manages synchronization and update of the scene tree and object informations caused by user interactions.

The first national QC Circle Convention sponsored by Industry Advancement Administration in 1975 was the beginning of employees group activity from a national point of view. Subsequently some events such as the firs Nationwide Factory Seamaul activity small Group Convention, which was supervised by the ministry of Trading and Industry and Factory Seamaulundong promotion Center, paved the way for proliferation of the group activity through all kinds of manufacturing. Although since November 1982 these two conventions has been united, many problems have been disclosed that are against the basic principles more or less. Worker's group activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. In practice, however, many groups are so typical and so impetuous of the material effect that it is worried to be inclined to outform rather than contents. To prevent this point it is recommended that worker's group activity be promoted continuously and on the basis of the original principle of small group activity to obtain practical and rich results, and systematically to be more effective and active considering the managerial environment and the intellectual level of the consisting members.

e-Business 환경이 다양화되고 활성화되면서, 전자적으로 교환되는 문서의 종류와 형태가 다양해지고 있다. 다양한 문서 형태를 지원해야 하는 요구사항이 대두되고 이를 충족하기 위해 하나 이상의 문서 변환 시스템을 도입하여 사용하고 있다. 기존의 문서 변환 시스템은 하나 또는 두 가지의 문서 형태만을 지원함으로 인해, 동시에 다양한 문서 형태를 지원할 수 없는 단점이 존재하였다. 또한 단일 형태의 문서 변환만을 지원하고 있어 문서 형태별 변환 기능을 지원할 수 없고 파싱된 문서 요소와 비즈니스 로직이 혼합되어 순차적으로 처리됨으로써, 처리가 완료되기 전까지 하나의 트랜잭션으로 처리되고 있다. 변환 절차가 하나의 트랜잭션 내에서 처리됨으로 인해 정보의 재사용성이나 효율적으로 시스템 자원을 사용할 수 없었다. 이러한 문제를 해결하기 위해 본 논문에서는 문서 형태별 비즈니스 로직을 포함하는 전자문서변환 시스템을 도메인 모델방식 개념을 기반으로 설계, 구현함으로써 개선 가능한 시스템을 제안하고자 한다. 본 논문은 제안 시스템을 통해 기능별로 모듈화가 가능하게 되고 트랜잭션도 단계별로 분리하여, 처리 복잡성을 해결할 뿐 아니라, SOA(Service Oriented Architecture)기반의 진보된 개념을 쉽게 적용 가능한 확장성을 갖추는데 그 의의가 있다.

The several wearable devices are not able to communicate through cable due to its portability. The wireless communication method is used because of its good communication quality and group action features when the several wearable devices communicate with each other. In this paper, we proposed the group decision algorithm for grouping display of the several wearable devices. It means that recognize as a group member after measuring distance in the wireless communication environment. The result of experience showed that the group-type display of several wearable devices method overcome the limit of the display of single wearable device.

This study is to examine whether elementary science textbooks in Korea and Singapore are applicable to flipped learning. By comparative study we sought to identifying appropriate features of science textbooks for learner-centered teaching. We analyzed text pages on the unit of 'Working of electricity' in Korean elementary science textbook for sixth grade and three chapters of 'Electric circuits, Using electricity, Conductors of electricity' in Singaporean elementary textbook, 'Science : My pals are here!'. We designed evaluating frameworks for science textbooks based on the four pillars of flipped learning. and applied it to 10 elementary teachers evaluate two textbooks. They evaluated textbooks with Likert Scale items and wrote detailed statements and exemplars about their choices. We analyzed the teachers' evaluative descriptions inductively and chose commonly mentioned characteristics. Based on the analysis, we got to the conclusion about specific features of two elementary science textbooks in terms of flexible environment, learning culture, intentional contents, and teachers' expertises. Implications for improving science textbooks towards flipped learning and learner-centered teaching through comparative study were discussed.

The main purpose of the present study are as follows: First, through the extensive literature review, we tried to find out environmental changes in the management thoughts. Second, as we found a new paradigm on valuation-oriented management thoughts, we argued that cost/management accounting information should play key roles in creating values. Third, we pointed out that when firms used only financial performance measurements, problems could take places. Finally, especially to promote the organizational effectiveness and efficiency, we stressed that firms should use the balanced scorecard approach in performance measurements of its own organizations and personnels.

Elementary education is the most fundamental education phase to cultivate a minimum natural quality for basic people life. Because elementary school is a very important step to be a base of lifelong education, it has to lead students to develop a capability of information utilization and rear the ability of self-leading study. Accordingly the elementary school library must be made and managed to cope with a new environment of education and information, as well as it must be a appropriate facilities for the contents of the 7th course of study : The aim of the 7th course of study is to rear the autonomous and creative Korean who lead the age of globalization and information-oriented. It is an ideal that the school library has a separate building for itself as the general information center but it is not easy to do in our conditions. Accordingly when it Is located in a school house, it has to be at the center within easy access of other related rooms such as a classroom and school house. Therefor making a plan and designing a school building, the school library has to be considered preferentially as a main facilities in order to make a school to accept the future.

Retail space itself could be one of the marketing strategies, through creating space, and communicating brand identity. Especially for innovative products, such as mobile technology products, store is not just to sell products but to provide experiences so that users can fudge usefulness of products and reduce uncertainties to adopt the products. The purpose of this study is to investigate how environmental features and physical artifacts contribute to promote experiences of innovative products in stores and how physical environment help to establish brand identity. For this study, site visits, observation, and literature review were conducted. For case studies, three retail spaces (Apple, Iriver, Sony) and one service space(TTL) were selected. Compared to the service space, three retail spaces have more transparent and open store front design characteristics. For the experiences of shoppers, products displayed in a radial shape, round shape, column shape, and around peripherals of the stores. A service oriented space, TTL zone is differentiated from three retail spaces in terms of layout, store front design, and experience areas. Compared to the traditional stores selling innovative products, the case stores showed more warm atmosphere using various shape, wood materials, lighting fixtures and furniture.

This paper deals with the design of the manufacturing information system which is able to respond rapidly to various requirements of customers in make-to-order environment. The system is required to maintain a consistent flow of information from the start to the end. For this, we adopt an approach based on Information Engineering (IE) methodology, which consists of four stages: planning, analysis, basic design, and detail design. The first is a planing stage which establishes a project goal and organizes a project team. In the second stage, current activities are analyzed and problems are defined. The basic design is accomplished in the third stage, where a project scope is defined and an overall feature of the new system is presented. And then, in the last stage, the operation plan of each subsystem is drawn up in detail and all subsystems are integrated. This study applies the methodology to the case of H company and focuses on designing forms which are easy-to-write, easy-to-understand, and field-oriented. These forms are interrelated and can be used for systematic analysis and design. By applying them to the system design, we have obtained effect of reducing cost and time.
