The objective of this paper is to analyze the effect of the defense quality certification system on the military user's dissatisfaction. In this paper, an empirical research is performed to compare the effectiveness of ISO 9000 : 2000 and Korea Defense Quality Certification system 0050-9000. The research result shows that (1) the Defense Quality system is better than ISO 9000 : 2000 to reduce the military user's dissatisfaction level. (2) the Quality Assurance types 4, 5 have more user's dissatisfaction than types 2, 3. (3) small and medium sized companies have more user's dissatisfaction than large companies.

ISO 140-1 recommends installing diffusing elements in the room if there are large variations of the sound pressure level caused by strong standing wave. Also it requires that reverberation time should not be long or short. In accordance to this regulation, we adjusted the reverberation time in the range of $1{\sim}2$ sec by using 4 types of diffusing elements. This paper demonstrates how to balance the reverberation time in the range of $1{\sim}2$ sec by using several types of diffusing elements.

국가GIS가 주요 정보인프라 역할을 수행하기 위해서는 구축되는 공간정보에 대한 표준화가 필수적이다. 본 연구에서는 국가GIS 표준화 내용에 어떤 것이 있으며 어떠한 방향으로 추진되어야 하는지를 외국사례 분석을 통해 살펴보았다. 미국, 호주, 일본, 영국 4개국의 국가GIS 표준화와 ISO/TC211, OGC의 표준화를 분석한 결과 첫째, 국가GIS 표준화는 지리정보 표준과 지리정보 서비스 표준의 두 방향으로 추진되어야 하며 둘째, ISO/TC211 프로파일을 통해 국가GIS 표준을 개발하는 것이 바람직하며 셋째, 지리정보 어의(語義) 정의를 개체-관계의 데이터 내용으로 표현해야 하며 넷째, 지리정보 서비스 표준 연구에 적극적인 관심을 가져야 할 것으로 나타났다.

The purpose of this study is to analyze the effectiveness of process approach for business performance of a company certified with ISO 9000 : 2000 quality management system. The result of this empirical research were identified as follows. Documentation and an intelligence process appeared with a preference matter in an influence to reach to a business performance of a company through the organization which established a process approach. It reveals that the process approach of quality management system might affect positively for customer satisfaction, product qualify, financial results and cost reduction.

Recently classroom monitoring is becoming important since the lecture is being held in the classroom and academic institutions are interested in the quality assurance. Some institutions have adopted ISO 9000 systems and constructed monitoring system through measurement, analysis and improvement. In this study quality assurance problems in academic institutions and the requirements of ISO 9001:2000 will be briefly discussed. Next we will investigate how to monitor the lecture in the classroom(in-class) using statistical process control techniques such as control charts. Then case study will be given to illustrate the technique to use appropriate statistics. Finally how to monitor the learning process during in-class and after-class will be proposed.

국제표준화기구 ISO와 ITU-T에서는 ID 관리 기술 관련 표준화를 리드하는 연구그룹을 운용하여 이 분야의 표준화를 주도하고 있다. ID 관리 기술의 표준화를 ISO가 먼저 시작하였으나 현재는 ITU-T가 보다 더 다양한 분야에서 폭넓게 표준 개발을 진행하고 있다. 현재 ID 관리 기술은 기존의 ID 관리 시스템들 간의 상호호환성을 제공하려는 기술에 초점이 맞추어 개발되고 있고 사용자의 개인정보를 공유할 시에는 사용자 중심의 프라이버시 기술을 제공하는 방향으로 진행되고 있다. 본 논문에서는 현재 ISO 및 ITU-T에서 이미 표준화된 ID 관리 관련 국제표준들과 개발 중에 있는 표준초안들에 대해 간단히 소개하고, 기타 다른 표준화 기구들의 동향을 파악하여 향후 추진방향을 제시하고자 한다.

In this paper, a CMOS complementary bridge rectifier for driving RFID transponder chips is presented. The proposed RFID CMOS complementary bridge rectifier is designed with two NMOSs at the input, which are configured by cross-connected gate structures, and two PMOSs and two NMOSs at the output, which are configured by diode-connected MOS structures. Output characteristics of the proposed rectifier are analyzed with the high frequency small-signal equivalent circuit and verified with SPICE for RFID operating frequencies of 13.56 MHz HF for ISO 18000-3, 915MHz UHF for ISO 18000-6, and 2.45 GHz microwave for ISO 18000-4. Simulation results show well-rectified and high enough DC output voltages for driving the low power microchip in the RFID transponder for the frequency range from HF to microwave. DC output voltages are dropped by only around 0.7 V from the input peak-to-peak voltages.

Installation damage of 3 types of geogrids were evaluated with compaction condition. This experimental test was in accordance with ENV ISO 10722-1. Tensile strength of geogrids were decreased with number of cyclic compaction loading without regard to kind of filled material and it was seen that strength decrease tendency showed the dependence on geogrid type. Woven and warp-knitted type geogrids showed the bigger decrease of tensile strength than welded type geogrids.

This paper considers supplier selection process for e-business & ISO 9001 quality management system environments. Determining suitable suppliers in the electronic commerce has become a key strategic consideration. However, the nature of these decisions is usually complex and unstructured. In this paper, a Quality Estimated Supplier Selection (QESS) model is proposed to deal with the supplier selection problems in the e-business(Business to Business: B to B). In the supplier selection, quality management factors will be considered for the first time, and then price, and delivery etc. In the first level, we deal with the quality management factors such as quality management audit, product test, engineering man-power, capability index and training time etc., based on the five point scale. In the second level, a QESS model determines the final solution by considering factors such as price, production lead-time and delivery time.

In this work, standardization trends related carbon nanotubes and international standardization activities in the ISO/TC229 and IEC/TC113 were introduced. The movement toward development of carbon nanotube standard began in the nanotechnology council under the IEEE in 2005. KATS has also run the carbon nanotube standardization committee to support commercialization of product containing carbon nanotube through standards since 2004. The Korean Standards such as KSD2711, 2712, 2717 were established.
