우리나라의 과학기술은 선진국 수준에 이르고 있지만, 이를 뒷받침하는 표준/규격 분야는 그 수준에 못 미치고 있다. 이를 극복하기 위해서 본 연구에서는 미국 규격체계의 발전 동향과 우리나라의 국가표준(KS, KlCS) 및 국내민간 규격체계에 대해서 살펴보았다. 이를 바탕으로 국내 국방 표준/규격 체계의 현 실태를 분석하고 3가지 측면에서 개선방안을 제시하였다. 첫째, 국방표준 분류체계 분야에서는 국방 분야에서 표준, 규격, 핸드북을 명확하게 정의하고 국방 표준과 국방 핸드북의 제정대상을 식별하였다. 둘째, 국방표준 제정절차 분야에서는 민간주도(상향식)형의 표준/규격 제정절차를 제시하였고, 마지막으로 '국방규격작성 표준지침' 분야에서는 국방 표준, 규격, 핸드북의 표기법 및 현재 도면번호 체계의 한계를 극복할 수 있는 개선안을 제시하였다.

Risk Based Oversight is a way of performing oversight, where planning is driven by the combination of risk profile and safety performance. Risk Based Oversight enables prioritization and allocation of State's safety management resources commensurate with the safety risk profile of each service provider. This paper presents the concept of Risk Based Oversight and applies it to the current Korean aviation safety oversight process. In particular, this study presents a method for generating operating profiles, one of the key concepts of Risk Based Oversight. Operations Specifications of Part 121 Airlines can generate operating profiles. In this study, a practical study was conducted to generate the operating profile and scoped DCTs using Part 121 Airlines's Operations Specifications.

Determination of operational dimensions and tolerances is complex if there exist inconsistencies between operational and design specifications. Dimension and tolerance charts (D&T charts) have been used to establish the relationships among operational dimensions in complex machining. This chart proves that individual operations can be harmonized when they are interconnected. However, it is hard to generate the chart manually. Because operational dimensions and tolerances must meet the design specifications, the dimensions and tolerances of interconnected operations have to be verified serially for economical operations. In this paper, the chart is automatically generated from the interconnected operations. More importantly, all operational dimensions and tolerances displayed in the chart have been verified by using LP to meet the design specifications. Finally, the chart is converted to an operational routing sheet that contains a detailed process plan along with cutting speed, feed rate, and operational references based on material hardness, surface finish, and tool nose radius.

본 연구에서는 외국의 국방표준화 정보관리 발전동향을 살펴보고 우리나라 현 실태를 분석한 후 민수-국방분야에 공통 적용가능한 규격/표준 공통 분류목록의 제정과 이를 바탕으로 한 표준화 정보기반 통합DB의 구축 및 국방표준화 정보체계의 구축방안을 제시하였다. 규격/표준 공통 분류목록은 국방규격과 한국산업표준의 그룹핑을 통해 표준화 대상식별에 관한 보다 효과적인 방법을 제시하였으며, 표준화 정보기반 통합DB 구축을 통해 규격/표준과 다양한 정보들과의 상호참조 기반을 제공하였고, 표준화 정보체계를 통해 민수-국방분야 전반에 걸친 규격/표준정보 활용의 토대를 제시하였다.

OGC(Open GIS Consortium)는 웹 GIS 환경의 상호 온용을 제공하기 위해, 웹 매핑 테스트 베드를 통한 맵서버와 GML 명세를 정의함으로써 새로운 웹 매핑 기술을 제안하고 있다. 이 환경에서 맵서버는 다양한 데이타 서버들의 지리정보를 GML로 변환하여 클라이언트에게 제공하고, 클라이언트는 전송받은 GML 데이타를 웹 브라우저에 출력한다. 이러한 웹 매핑 테스트베드는 웹 GIS 환경에 분산 저장된 GIS 정보의 발견, 접근, 통합 및 출력 방법은 제공하지만 GIS에서 필수적인 공간연산을 수행하는 방법은 제공하지 않는다. 본 논문은 웹 환경의 다양한 데이타 서버들로부터 중첩되어 전송된 GML 데이타에 대한 공간연산을 수행하는 방법을 제시한다. 이를 위해 W3C에서 XML 문서의 분석을 위해 제시한 DOM과 OGC에서 개방형 GIS 시스템의 구현을 위해 제시한 OpenGIS 단순 피처(Simple Features) 명세를 기반으로, 웹 GIS 환경에서 GML 데이타에 대한 공간연산을 지원하는 GDOM(Geographic Document Object Model)을 설계하고 구현한다. 그리고 웹 매핑 테스트베드 환경에서 클라이언트가 GDOM을 이용하여 공간연산을 수행하는 과정 및 결과를 보인다.

This paper describes a cell programming environment that deals with problems associated with programming Flexible Manufacturing Cells(FMCs). The environment consists of the cell programming editor and the automatic generation module. In the cell programming editor, cell programmers can develop cell programs using task level description set which supports task-oriented specifications for manipulation cell activities. This approach to cell programming reduces the amount of details that cell programmers need to consider and allows them to concentrate on the most important aspects of the task at hand. The automatic generation module is used to transform task specifications into executable programs used by cell constituents. This module is based on efficient algorithm and expert systems which can be used for optimal path planning of robot operations and optimal machining parameters of machine tool operations. The development tool in designing the environment is an object-oriented approach which provides a simple to use and intuitive user interface, and allows for an easy development of object models associated with the environment.

Limiting conditions for operations (LCOs) are evaluated dynamically using the tool of system dynamics. The LCOs de-fine the allowed outage times (AOTs) and the actions to be taken if the repair cannot be completed within the AOT. System dynamics has been developed to analyze the dynamic reliability of a complicated system. System dynamics using Vensim software have been applied to LCOs assessment for an example system, the auxiliary feed water system of a reference nuclear power plant. Analysis results of both full power operation and shutdown operation have been compared for a measure of core damage frequency. The framework developed in this study has been shown to be very flexible in that it can be applied to assess LCOs quantitatively under any operational context of the TS in FSAR.

This paper describer a design expert system which determines the design values of shadow mask using Case-Based Reasoning. In Case-Based Reasoning, it is important to both retrieve similar cases and adapt the cases to meet the design specifications exactly. Especially, the difficulty in automating the adaptation process will prevent the designers from using the design expert systems efficiently and easily. This paper explains knowledge-based design support systems for shadow mask through neural network-based case adaptation. Specifically, we developed 1) representing design knowledge and 2) adaptive case-based reasoning method using RBFN (Radial Basis Function Network).

A mixted integer non-linear programming model which has the object function as minimizing building costs, and constraints with the functions for carrying capacity and service level of queueing time is developed. By using the proposed model, the most adequate on a building and the most economical elevator's specifications could be determined by sequential search method like complex method.
