The AS 9100 aerospace standard has become the aerospace quality management system standard agreed to, instead of ISO 9001 and MIL-Q-9858A by international aerospace manufacturing companies. In this paper correlative requirements of each of the standards are compared and analyzed. Then the evolutionary concept and its direction is proposed as a guide to participate in the preparation and establishment of current aerospace quality management systems. This study is applicable to the future as well as present aerospace manufacturing activities throughout the world.

IEC 60300 series, the international standards on reliability management system are newly developed and introduced rapidly worldwide. In order to meet this fast-changing situation, it is necessary to apply them to the Korean industries effectively. It includes the establishment of the infrastructure such as documentation of Korean Standards, introduction of test equipments and test manuals, accreditation of the certification bodies and training of the specialists etc. IEC 60300 is upgraded management system of the ISO 9000 and ISO 14000. In this regard, the Korean companies which were certified with the ISO 9000 or 14000 should endeavor to find new strategies and methods to be certified with IEC 60300. This paper introduces a Quantitative method of estimating the level of the reliability management system by applying the MIR(Maturity Index on Reliability) technique. This enables the estimation of the operation level of the system and can upgrade the maturity level of it.

The production, processing, sale and service of food materials are not subject to attainment via a single country. In accordance with internationalization of the world, issues related to food safety have emerged as critical international concerns and they are closely associated with the health and interest of domestic consumers, producers, manufacturers, and distributors. As a third party certification standards, ISO 22000 is in progress International Organization for Standardization(ISO) and the Draft International Standard(DIS) has already been presented on December 2004. The purpose of this study is to analyze the international standards, guidelines and legislation in regard of Food Safety Management System(FSMS) including ISO 9001, Hazard Analysis Critical Control Point(HACCP) and Product Liability(PL) so as to present Korean-model Food Safety Management System requirements and system establishment model.

With the development of indexing and retrieval techniques and the trends of information retrieval environment becoming more and more user-friendly, existing guideline for international thesaurus establishment standards and basic term relations currently used in thesaurus have become to longer adequate. The purpose of this study is to present solutions to expanding term relations which will fit new information retrieval environment. This report views standards for ISO 2788 and ANSI/NISO Z 39.19, and compares and analyzes 20 thesaurus basis term relations currently used both at home and abroad(14 overseas and 6 in Korea) to find out problems and limitations. Based on findings of the study, this report suggests how to expand thesaurus basic term relations to accomodate changes in information retrieval environment.

To operate UAV in the civil airspace, the airworthiness of UAV system have to be proven by the civil certification system. However, it is difficult for UAV to be certified by the existing certification system because the existing certification system has been developed for the manned aircraft. So, many civil aviation authorities and research institutes are studying developing airworthiness standards for UAV certification. To develop an airworthiness standards for UAV, the airworthiness level of safety have to be established based on UAV categorization. I would like to introduce an quantitative methods for establishing airworthiness level of safety of UAV based on UAV categorization and example of Smart UAV.

In evaluating sound performance of building, it is important to carry on tests and evaluations based upon residential sound performances. Korean Standards include test methods on sound performance, but don't include any code on evaluation methods. Therefore, evaluation methods from Japan or ISO have been used for evaluating sound performance in domestic so far. In this study, every regulation from ISO, JIS, ASTM, especially for airborne sound insulation against building and building element, is analyzed in order to apply to establishment of Korean Standards on a sound performance evaluation method in buildings.

This paper describes a design and implementation of the DFR(Document Filing and Retrieval) system. one of applications of DOAM(Distributed Office Application Model) which is the international standard in ISO(International Standards Organization). On the basis of the international standard, the DFR system is implemented on SUN workstation and PC/386 with C language, and its implementation is verified by tracing the association descriptor and primitives of service elements when its operation is tested between client and server. The result of this study shows that the DFR system can be implemented on the basis of the international standard, and makes a contribution toward the establishment of functional standards for the DFR system.

Offices and other multipurpose buildings commonly have suspended ceilings installed over room dividing wall. But Korean Standards don't include any code on test methods and test facility of the suspended ceiling system. Therefore, test methods and test facility from ISO or ASTM have been used for evaluating sound performance in domestic so far. In this study, every regulation from ISO, ASTM, especially for airborne sound insulation against suspended ceiling system, is analyzed in order to apply to establishment of Korean Standards on test methods and test facility of suspended ceiling system and materials.

Measurement of Co-60 gamma rays has been made for establishment of exposure standard and analyze it's overall uncertainties. Exposure rate determined by the charge mode method using vibrating reed amplifier with cylinderical type cavity chamber. The values of a variety of physical constants and the correction factors are evaluated. The resulting exposure rate is 690.81 R/h at the distance of 1m from the source and the related uncertainties is ${\pm}0.8%$
