  • This research is primarily intended to propose a new concept for aggregate control of impervious coverage using remote sensing and GIS. An empirical study for a case study site was conducted to demonstrate how a standard remote sensing and GIS technology can be used to assist in implementing the aggregate control for impervious coverage as intermediary between decision makers and scientists. Guidelines for a replicable methodology are presented to provide a strong theoretical basis for the standardization of factors involved in the aggregate control; the meaningful definition of land mosaic in terms of pervious areas, classification of pervious intensity, change detection for pervious areas. Detailed visual maps (e.g. estimation of impervious surface allowable) can be generated over large areas quickly and easily to increase the scientific and objective decision-making for the aggregate control. It is anticipated that this research output could be used as a valuable reference to confirm the potential of remote sensing and GIS in the aggregate control for impervious coverage.

  • An estimation of surface roughness value is a very important and difficult issue in grinding process. The definition of the D.A.R.F(Dimensionless Average Roughness Factor) has been made including the absolute average and tile standard deviation that are the parameters of the AE(Acoustic Emission) sign. The theoretical equation of the surface roughness applying the D.A.R.F has been derived from the regressive analysis and specified with respect to the availability through the experimental approach on the machine.

  • Substernal goiter may be defined as any thyroid enlargement that has 50 to 100 % of its mass inferior to the thoracic inlet. Ectopic substernal goiters are rare, and most substernal gaiters arise from cervical thyroid gland. Fifteen to fifty percent of these patients are asymptomatic. Symptoms, when present, are usually the result of tracheal or esophageal compression. Symptoms are often positional. Standard chest roentgenograms are often diagnostic, but computed tomographic or radioactive iodine scans may be helpful. In symptomatic patients or those in whom explorations are undertaken for diagnostic purpose or exclude carcinoma, surgical removal is indicated. Although cervical thyroids with substernal extension may be safely and successfully removed through a cervical incision, primary substernal goiters by definition derive their blood supply from within the thorax and are better approached by splitting the sternum or through a posterolateral thoracotomy. Recently we experienced a child fist sized secondary posterior mediastinal goiter in 55-year old female. The mass was completely removed through right posterolateral thoracotomy without any complications. The postoperative courses were uneventful.

  • In this study, by using the natural language processing of the field of artificial intelligence, automated index was performed. And then, the Natural Language Processing Interface for knowledge representation(NALPI) has been developed. Furthermore, the DEsign KnOwledge DataBase(DEKODB) has been also developed, which is designed to interlock the knowledge base. The DEKODB processes both the documented design-data, like a concrete standard specification, and the design knowledge from an expert. The DEKODB is also simulates the design space of structures accordance with the production rule, and thus it is determined that DEKODB can be used as a engine to retrieve new knowledge and to implement knowledge base that is necessary to the development of automatic design system. The application field of the system, which has been developed in this study, can be expanded by supplement of the design knowledge at DEKODB and developing dictionaries for foreign languages. Furthermore, the perfect automation at the data accumulation and development of the automatic rule generator should benefit the unified design automation.

  • 이 기종 시스템들간의 교환을 목적으로 사용되는 SGML(Standard Generalized Markup Language)문서는 논리적인 구조를 나타내는 구조를 나타내는 DTD(Document Type Definition )가 필요하다. 이러한 SGML DTD을 모델링하기 위해 기존에 여러 가지 방법이 제안되어 왔는데, 본 연구에서는 SGML DTD를 UML (Unified Modeling Language)클래스 다이어그램이 객체 모델로 사상시키는 알고리즘과 데이터 베이스 스키마 형태로 나타내기 위한 형식 모델을 제안한다. 본 연구에서 제안한 사상 규칙들과 알고리즘을 이용하면 SGML DTD을 보다 자연스럽게 객체지향 모델링하므로 데이터베이스 스키마로 변환이 용이하며, 형식모델을 데이터베이스 스키마 형태를 정의하므로 객체지향적인 문서 처리와 검색을 위한 효율적인 환경을 제공하게 된다.

  • In the rapidly changing field of Management Information Systems, the definition and educational programs must be continually reevaluated and revised. A study was conducted to find a way to which the modeling principle is applied for redefining the identity of Management Information Systems as an independent academic field and to develop a plausible MIS curriculum based on the modeling principle. Previous researches on the MIS frameworks, knowledge and technology requirements for IS professionals, and standard MIS curriculums were reviewed thoroughly. For this study, the Kantian cognitive model was adopted as a basis of modeling principle. The result shows that modeling ability has been the core competence of IS people in the field of MIS. The applicability of a modeling principle is also verified in establishing the identity of MIS and developing a normative MIS curriculum. For the MIS field to thrive as an independent academic field and research discipline, it is believed to be imperative for the discipline to have a unique educational goals distinguished from both other management areas, and sub-fields of computer science.

  • 본 논문은 XSD(XML Schema Definition)기반의 XML 문서를 웹, 엑셀 환경에서 다양한 관점으로 볼 수 있도록 템플릿 서비스를 제공하기 위한 시스템이다. 템플릿 서비스는 데이터스킨 서버에서 스킨을 통하여 서비스되며, XML 문서를 다양한 문서로 변환할 수 있도록 한다. 예로 XML 문서를 HTML로 변경하는 경우 XSLT(Extensible Style Language Transformation) 를 사용할 수 있고, 엑셀 문서로 변환할 경우 엑셀 템플릿을 만들어 스킨으로 제공할 수 있다. 스킨은 다양한 방법으로 구현될 수 있으며, XML 문서에서 사용자가 원하는 문서로 만들기 위한 미들웨어 역할을 한다. 사용자는 데이터스킨 변환 서버에 접속하여 가지고 있는 XML 정보들을 차트, 그래프, 수식 등으로 쉽게 변환할 수 있을 뿐만 아니라 OWC(Office Web Component)로 쉽고 빠르게 문서를 변환 할 수 있도록 한다.

  • This article focuses on integrating institutional mediation systems, especially the analysis of the leading ADR operation. Mediation is a process in which an impartial third party, a mediator, facilitates the resolution of a dispute by promoting voluntary agreements by the parties to the dispute. A mediator facilitates communications, promotes understanding, focuses the parties on their interests, and seeks agreement. These standards give meaning to this definition of mediation. Standard mediation clauses are construed as broadly as possible, and mediation is compelled unless it may be said with positive assurance that the mediation process is not susceptible to an interpretation that covers the asserted dispute. Performing the conflicts check early in the process helps in eliminating any awkwardness or delays caused by making disclosures after mediation commences. Mediator impartiality is central to the mediation process. A mediator should mediate only those matters in which she or he can remain impartial and evenhanded. If at any time the mediator is unable to conduct the process in an impartial manner, the mediator is obligated to withdraw.
