  • 민수용 항공기 산업에서는 해당 제품의 성능이 우수 하더라도 항공기의 항행 안전성을 확보하기 위하여 필요한 안전성 요구사항에 대한 적합성을 인정을 받지 못하면 법적으로 항공기에 사용 될 수 없는 특성이 있다 [1]. 이와 같이 다양하게 적용되어 지고 있는 항공 전자장비의 항행 안전성을 위하여 민간용 항공기에는 기술표준품 인증 제도를 시행하고 있다. KTSO-C113은 항공기용 다목적 전자식 디스플레이의 기술표준품을 인증하는 최소성능표준을 포함하고 있다. 기술 표준품 형식승인은 설계 및 제조에 대한 승인을 의미하여 항공기 장착하여 사용하기 위해서는 별도의 승인이 필요하다. 본 논문을 통하여 항공기용 다목적 디스플레이의 기술 표준품 형식승인 제도 및 인증 요구조건을 소개하고 적합성 입증을 위한 인증 사례를 제시한다.

  • In this paper, we consider various international and local standards and applied ontology concepts which are used in Semantic Web, to make more structured test methods/procedure. Based on the ontology concept, we classify test method as three categories (i.e., conformance test, interoperability test and performance test), and make test structures for each category. We believe that this research provides test methods which reflect various standards as well as the guidelines for users to construct RFID device software more structurally.

  • This study aims to find out sector effects with the appraisal of building energy systems of urban ecosystem considering cost effects and environmental constraints condition such as climatic change factors including $CO_2$ gas which are not dealt in the institutional boundary as components standards and performance standards on energy performance of each part of a building applied on heavy energy spending buildings at present. The results of the appraisal of building energy systems shows that the existing building energy systems are not enough to fulfil the environmental condition under the environmental constraints supposing QELROs(Quantified Emission Limitation and Reduction Objectives) of carbon-dioxide exhaust. Henceforth, it is needed to fulfill the environmental criteria required by the Climatic Change Agreement for improving the adiabatic performance of each part of a building and active using of the solar energy.

  • The physical performance of high-strength concrete deteriorates when exposed to high temperatures such as fire. In particular, in the case of ultra-high-strength concrete, there is a high possibility of explosion due to internal water pressure and thermal expansion due to the tight internal structure. In this paper, a fire resistance certification test was conducted for field application of ultra-high-strength fire-resistant concrete, and the fire resistance performance (temperature rise of main rebar) was compared according to the structural concrete cover thickness. As a result, when the covering thickness was 40 mm, three structures did not meet the certification standards, and when the covering thickness was 50 mm, all structures met the fire resistance certification standards.

  • The objectives of this study is to classify evacuation types, derive the characteristics of 4 types, develop and discover evacuation routes within the performance hall space, and present the statistical classification results of the evacuation classification model by classification type. To achieve this purpose, the characteristics of each evacuation type's four types are applied through a network reliability analysis method and utilized for institutional improvement and policy. This study applies for the building law, evacuation and relief safety standards when establishing a performance hall safety management plan, and reflects it in safety-related laws, safety standards, and policy systems. Statistical data by evacuation type were analyzed, and measurement characteristics were compared and analyzed by evacuation types. Evaluate the morphological similarity and reliability of evacuation types according to door width and passage length and propose the install position of evacuation guidance sign boards. The results of this study are expected to be used as basic data to provide operation strategies for safety facility evacuation information sign boards according to evacuation route classification types when taking a safety management plan. The operation strategy for the evacuation sign boards installation that integrates employee guidance and safety training is applied to the performance hall safety management plan. It will contribute to establishing an operational strategy for performance space safety when constructing performance facilities in the future.

  • Establishment of the Quantum Hall Resistance(QHR) Standard as national resistance standard using a room temperature DCC resistance bridge is described. A simple method are used to obtain the current dependence and error of 10: 1 ratio of the bridge instead of the method using a cryogenic resistance bridge. Measurement uncertainty of the system is estimated as $0.14{\times}10^{-6}$ and it is confirmed that the QHR standard is agreed well with the QHR of other NMIs using the cryogenic resistance bridge within the uncertainty, More improvement about performance of the QHR device and 10: 1 ratio accuracy is still under progress.

  • This thesis introduce the organization system and office regulation of standardization administrative organization for the change of times, also suggest improvement plan for its effective management. The main improvement plan refer to the standardization administrative organization\`s work, this thesis suggest, 1. Readjustment of national standardization system and effective reorganization for standards information organization. 2. For industrial standards system, the korea industrial standards should be maintained uniform system, So decentralized korea industrial standard at government ,must be unified and maintained to unique policy for its effective improvement. 3. To strengthen with international standards organization, a institutional device, budget funds, and expert should be backed up. 4. For training and education of expert, Refer to the performance of one\`s duty, the proper expert should be chosen and posted. Also, systematic training and education system for expert must be developed, So they can be on duty continuously, Finally, this thesis suggest that the necessity of systematic and unique policy must be established for high position at international area. Since the limitation of data, the future research will be performed for budget funds and personnel setup.

  • The mass measurement of solid density standards using weight exchanger is described. KRISS(Korea Research Institute od Standards and Science) has several solid density standards. Their mass have been measured manually only using a mass comparator(Mettler, 1kg - 0.01mg). However, the uncertaity of the manual mass measurement is up to 300 microgarm much more than 32 microgram of advanced NMIS(National Metrology Institutes) for 1 kg silicon sphere which is primary density standards due to an eccentric error and buoyancy correction error. The new system with a weight exchanger is designed and built to improve the measurement accuracy. It comprises a weight exchager, a mass comparator, air density instruments, and application program for automatic measurement. It is evaluated by measuring several elements in an air tight chamber to verify the performance of it.
