The organizations that adopted ISO 9000:1994 have upgraded to ISO 9001:2000 family through transition period by December, 2003. This paper focuses on the implementation of ISO 9001:2000 QMS in Busan and Kyungnam provinces where most machinery and metal manufacturing companies are located. Based on the questionnaire survey, we calculate ordinal association measures of requirements questions, perform factor analysis, and test three hypotheses to ascertain if there is any difference in implementing ISO 9001:2000 QMS. Results show that a professional manager-CEO maintains QMS general requirements(4.1), work environment(6.4), measurement analysis and improvement general(8.1), and monitoring and measurement(8.2) better than an owner-CEO. In addition, it has been found that customer focus(5.2) and improvement(8.5) are well maintained in companies by internal developmental reasons, and infrastructure(6.3) and purchasing(7.4) are well maintained by companies with long term implementation.

In this study, high-density plasma etching characteristics of ITO(indium tin oxide) films used for transparent electrodes in display devices have been investigated. The etch characteristics of ITO as a function of $Ar/CH_4$ gas mixtures were analyzed using QMS(quadrupole mass spectrometry), OES(optical emission spectroscopy), and ESP(electrostatic probe). ITO etch rates were increased with the addition of moderate amount of $CH_4$ to Ar due to the increased chemical reaction between $CH_3$ or H and ITO in addition to the physical sputtering of ITO by Ar ion bombardment. However, the addition of excess amount of $CH_4$ decreased the ITO etch rates possibly due to the increased polymer formation on the ITO surface. Also, the measurement data obtained by QMS and OES suggested that $CH_3$ radicals are more activity involved in the etching of ITO compared to H radicals.

Today's dynamic competitiveness requires an organization to improve its performance measurement and management. Quality Management Systems (QMS) abound, the main ones being: ISO series, Malcolm Baldridge National Quality Award (MBNQA), European Forum for Quality Management (EFQM), Six Sigma Business Scorecard and the Balanced Scorecard. Based on the literature, the IPMMM (Integrated Performance Measurement and Management Model) identified 7 key synthesized factors: leadership, strategy management and policy, customer and market, learning and growth, partnership and resources, internal processes and business results that are employed to investigate the key performance indicators of a car assembler using the Delphi methodology. In the 2 rounds of Delphi panels consisting of 20 senior management personnel, the $1^{st}$ round of 198 indicators in the IPMMM yielded 90 indicators. The $2^{nd}$ round yielded 43 performance indicators with 18 rated as critical based on the % assigned in the $1^{st}$ and $2^{nd}$ priority rating of "very important factor" and "key performance indicator" that must be ranked high on both of the priorities. The very critical indicators appeared to be: defect percentage and first time capability (tie in $1^{st}$ place) and revenue, goal setting, customer satisfaction index, on-time delivery, brand image, return on investment, Claim Occurrence Ratio, and debt being ranked from $3^{rd}$ to $10^{th}$. It can be surmised that an organization can identify and develop an appropriate set of performance indicators through the Delphi methodology and implement and manage them based on the Balanced Scorecard.

우리나라 건설공사의 품질관리체계는 관련법에 근거한 규정의 조합과 시공자가 구축한 ISO/KS A 9001에 의한 품질경영 시스템의 운용에 의한 방법의 혼합형이다. 이 두 가지의 품질확보체계는 상호 보완적이며 통합된 체계로 운영되어야 하나, 시공자의 품질경영시스템을 활용하지 못하고 법에서 정한 기준과 방법, 절차 등의 규정에 따라 모든 공사에 있어서 일상화된 품질관리업무가 수행되고 있다. 이러한 현상은 ISO규격이 도입된 이래 지난 10여 년간 계속된 문제점으로 개선이 요구되고 있다. 품질관리의 철저를 목표로 고객 만족을 위한 예방적 품질관리사고를 정착하는 일은 건설산업의 당면과제이다. 이에 본 논문에서는 건설현장 의 실무자를 대상으로 품질관리 관련 의식에 관한 설문조사를 실시하였으며 그 결과를 토대로 건설공사 품질관리 체계의 운용에 대한 만족도를 정리하고, 나아가 향후의 개선방안에 대한 논점을 제시하고자 한다.

The performance measurement of construction firms is considered as a competitive advantage to develop and improve their performance to have place in the market and stay able to face the continuous challenge. Egyptian construction firms (ECF) started recently to adopt quality management system (QMS) as a way to develop and improve their performance as previous studies showed. However, measuring that performance to include all the firm's aspects in a competitive way is a crucial process for the ECF's culture. The research is trying to indicate the role of the QMS implementation in measuring performance (MP) through developing a model for measuring performance on the organization level, and explore its impact on the organization that adopt quality management system. This model is based on specific elements and their related indicators which have been derived from national approaches and models of measuring performance (benchmarking, quality awards and six sigma).Elements determination and the status of their real practice has been investigated through a questionnaire to a representative sample of ECF. This model determines the performance level (PL) of the organization that measured by a mean of a point system. Weights of the elements in the point system considered both the elements' importance in the international models and its real practice in the Egyptian construction firms. So, the final outcome of the model reveals the level of firm performance that helps the firm to identify the weak points against the strong ones, Confirm the priorities and identify new opportunities for developing, and Check the position of the company in the market among the others. Another questionnaire has been developed to be distributed on a group of Experts on measuring performance for the purpose of model validation. The majority of surveyed experts agreed that the proposed model can be applied effectively.

사중극 질량분석기(Quadrupole Mass Spectrometer, QMS) 이온전류의 안정성은 진공공정 가스를 모니터링 하는데 중요한 요소 중 하나이다. 진공챔버에 질소가스를 주입하여 압력을 일정하게 유지하면서 시간에 따른 이온전류의 변화를 모니터링 하였다. 진공챔버는 측정하기 전에 잡음신호를 줄이기 위해 ${\sim}3{\times}10^{-9}\;Torr$ 까지 배기하였고, 두개의 이온소스를 측정했다; 하나는 오염된 것으로 갈색 또는 검은색을 띄고 있고 다른 하나는 새 것이다. 질소 압력 $1{\times}10^{-5}\;Torr$에서, 오염된 이온소스의 이온 전류는 시간이 지남에 따라 더 빨리 감소했다. 대략 5.5 시간이 지난 후, 감소율은 새 것이 ${\sim}46%$이고 오염된 것은 ${\sim}84%$였다. 필라멘트 재질이 이온 전류감소에 미치는 영향을 관찰하기 위해서 텅스텐 선의 반을 산화이트륨($Y_2O_3$)으로 코팅하여 필라멘트를 제작하였다. 유사한 이온전류 감소현상이 재질이 다른 두 필라멘트에서 나타났는데 이것은 필라멘트 재질에 의한 온도의 변화 즉 baking 효과로는 이온전류 감소의 원인을 개선할 수 없다는 것을 의미한다. 전반적으로 이온전류의 감소율은 필라멘트 재질보다 이온소스의 오염과 더 밀접하게 관계되어 있다.
