본 논문에서는 TMN개념을 도입하여 관리 망의 물리구조를 설계하는 것을 목표로 하였다. 통신망의 종합적인 관리를 위한 관리 망의 구조를 계층적으로 분석하여 하위계층에 해당하는 물리계층의 구조를 설계하였다. 특히 TMN개념을 이용하였을 때의 물리구조에 기본이 되는 TMN-DCN을 설계의 대상으로 하였고 신속한 관리정보의 송·수신으로 망 관리의 효율을 높일 수 있는 설계방법을 제안하고 설계를 실시하였다. 결과적으로 물리구조를 구성하는 총 링크설치 비용이 어느 정도(4.8-7.1%, 정도)증가 하지만 관리정보를 가장 빠르게 전송(약 5.0 %)할 수 있었다.

According to critics and architects, non-linear structure is not only an organic form of space, but also a form of space detached from modem style. Accordingly, non-linear structure can be accepted as an alternative to what has remained unsolved by deconstructionist. However, they are criticized for not clarifying the interdependent relationship between non-linearity of space and cognitive structure of human being. They ended up remaining the hypothesis just an intuitive and abstract one. This research began on the basis that their hypothesis is hard to be objectified, and it needs further inquiry. The purpose of this thesis is to explore how the redundant factors constitute non-linear structures of digital media centered space design. Geometric compositions of space structure were analyzed to define what types of redundant factors are contrived in the process of visual information. This study about the visual form, researching the Information Theory, and then offer a quantitative analysis that makes those more objective. Space structure and geometric composition were analyzed to define what types of redundancy are contrived in the process of visual information. In particular, I put higher theoretical emphasis on what characteristics are ensued in the process of structuring spaces than any other subjects. Followings are the conclusion of analysis. First, as a result of examining, we can assume that NOX' space structure is not a chaotic form, but has an operating the form of its own. Second, in case of curvilinear, the structure was found redundancy on mid deviation ratio and discontinuous circular fabric. Although most of their structures appeared complex with a higher coherent constant, they were found to be stable factors because of the low deviation ratio between systems. The amount of surplus information was stable structure as well.

본 논문은 유통정보 네트워크 활성화 방안에 대하여 효율적인 NDB(Network Data Base)을 설계하였다. NDB(Network Data Base)의 구조는 논리 구조, 격납 구조, 물리 구조로 형성되어 데이터는 하나의 레코드로서 표현되고 데이터들 간의 관계는 링크로서 표현되었다. 또한 데이터베이스의 논리적 구조를 표현한 자료 구조도(Data Structure Diagram:DSD)가 계층 모델로 나타내었다. 각 노드는 레코드 타입을 나타내었고, 타입들을 연결하는 방향을 지닌 링크, 논리적인 격납 형태로 구성되어 데이터베이스를 설계하는데 물리 매체상 서로 연관성 있게 설계되어 자료의 검색과 억세스 효율에 큰 영향을 미쳤다. 또한 설계된 시스템에 네트워크를 형성하고, 네트워크 표준화를 위해 OSI 환경하에서 POS(Point Of Sale)시스템을 이용하여 효율적인 유통 정보 네트워크를 활성화시켰다.

This study presents a database quality evaluation framework. As a way to build a framework, this study expands data quality management to include data transformation processes as well as data. Further, an information structure graph is applied to represent data transformations processes. An information structure graph is absed on a relational database scheme. Thus, data transformation processes may be stored in a relational database. This kind of integration of data transformation metadata with technical metadata eases evaluation of database qualities and their causes.

An information structure of large size hypermedia application is usually hierarchical, and the sibling nodes in this structure have same or similar tags and contents. a word "개그" that means the common set of sibling nodes in the hierarchical information structure is used in this paper. It proposes a design method that divides form and content from nodes and it proposes HTML page generation algorithm from forms and contents. This method has reusability of form, maintainability of documents and reduction of cost for authoring.

The split ground structure for microstrip structure can be used to protect analog/RF signal from SSN interference of digital circuits on PCB with common ground. However, the split ground structure gives rise to undesired emissions that may interfere with nearby circuitry due to the ground discontinuity. In this paper, we have proposed the modified structure, Dumbbell shaped SGS and the method to reduce the radiation by adding the lumped resistor on the proposed Dumbbell shaped SGS.

Weber Local Descriptor (WLD) is a stable and effective feature extraction algorithm, which is based on Weber's Law. It calculates the differential excitation information and direction information, and then integrates them to get the feature information of the image. However, WLD only considers the center pixel and its contrast with its surrounding pixels when calculating the differential excitation information. As a result, the illumination variation is relatively sensitive, and the selection of the neighbor area is rather small. This may make the whole information is divided into small pieces, thus, it is difficult to be recognized. In order to overcome this problem, this paper proposes Weber Symmetrical Local Graph Structure (WSLGS), which constructs the graph structure based on the $5{\times}5$ neighborhood. Then the information obtained is regarded as the differential excitation information. Finally, we demonstrate the effectiveness of our proposed method on the database of ORL, JAFFE and our own built database, high-definition infrared faces. The experimental results show that WSLGS provides higher recognition rate and shorter image processing time compared with traditional algorithms.

The drawing information takes the most essential part of construction information. The management of construction information through drawing information facilitates input, output and search process, thus helping maximize the usage of construction information by effectively sharing construction experience and drawing information. This paper shows how construction information can effectively used to increase the productivity of the construction process as a whole. Construction information was extracted and classified by the elements of building which are the basic and very end components of building, to accumulate information of each construction phase. Based on the result, the Element Breakdown Structure(EBS) was developed for the practical usage of construction information integration.

The 1995 Informatization Promotion Act was passed to advance the national quality of life and to develop national economy by promoting informatization, forming the ground of telecommunication industry, and realizing the advancement of telecommunication infrastructure. This article was written to review whether this act's purpose was being achieved by Korean government. Even if Korean informatization policy implemetation structure is strongly centralized around the Ministry of Information and Communication, Information policies are formulated and implemented among agencies. To explain this phenomenon, I suggested the following factors : (1) The Korean government's lack of informatization experiences, (2) The political abuse of information policy, (3) the conceptual rigidity on the structure of information superhighway, (4) the absence of the basic principles for electronic government, (5) the uniformed regional informatization.

Recently, e-business has very much attention in the management fields because it is expected to fundamentally change the way many business compete. Business that don't understand the changes and that can't change their operating model in time will be at a disadvantage. Information technology infrastructure and its management are key components of e-business The purpose of this study was to investigate the effects of information technology infrastructure and its management to the type of information systems used and the use of e-business. A total of 56 Korean firms responded to the survey instrument. There was indirect effect to the use of e-business from the information technology structure via communication capacity and direct effect from management type. The study also found that firms with less centralized forms of information technology were more frequent users of e-business, Firms that have more freedom in information technology decision making tended to be users of the new technology and take advantage opportunities that exits on the information technology.
