In 2008, a review was made to analyze the effect of the certification of ISO 9001 quality management system in the almost same methods used for a similar review in 2001. Based on the two reviews, this research is to compare and contrast the changes made in between. The results show that the overall satisfaction for the certification has increased over 7 years, along with other beneficial changes, such as decreased cost and increased productivity. However, there has been no significant change in the establishment of the quality management system and in the level of customer satisfaction. ISO 9001 quality management system construction appears which effects variously on the all enterprises management, therefore this is very important strategy for preparing the keen enterprises competition.

Purpose: The purpose of this paper is to design an integrated informatization system that can manage quality & KPI by integrating management systems in the aerospace and defense industry, and study the effect on KPI when applied to related companies. Methods: The 7 management systems required for integration in the AS&D industry were studied, and an empirical analysis was conducted for H company in South Korea for the application of e-QMS integrated informatization & KPI system based on security environment and open quality. Results: The results of this study were analyzed to have an effect on the improvement of customer satisfaction and the positive improvement of quality failure cost in the aerospace and defense industry. And it was analyzed that it works to continuously comply with ethical management and environmental laws and prevent safety accidents. Conclusion: The greatest significance of this study is that it attempted to build an e-QMS integrated system in the aerospace and defense industry. Considering that the case of integrated management system and integrated operation of KPI in related industries has not been introduced in the existing literature, the results of this study will be shared as a meaningful preceding study in the era of digital quality information. In addition, the fact that the open-quality quality innovation methodology emphasizing measurement(M), tracking(T), and connection(C) was actually applied in an AS&D company and its effectiveness was objectively proven. It is expected that it will be a good paper for follow-up research.

In this study, BST thin films were etched with inductively coupled $CF_4/(Cl_2+Ar)$ plasmas. The etch characteristics of BST thin films as a function of $CF_4/(Cl_2+Ar)$ gas mixtures were analyzed using quadrupole mass spectrometry (QMS) and optical emission spectroscopy (OES). The maximum etch rate of the BST thin films was 53.6 nm/min because small addition of $CF_4$ to the $Cl_2/Ar$ mixture increased chemical effect. The optimum condition appears to be under a 10 % $CF_4/(Cl_2+Ar)$ gas mixture in the present work.

In this study, PST thin films were etched with inductively coupled $Cl_2/(Cl_2+Ar)$ plasmas. The etch characteristics of PST thin films as a function of $Cl_2/(Cl_2+Ar)$ gasmixtures were analyzed by using quadrupole mass spectrometer (QMS). Systematic studies were carried out as a function of the etching parameters, including the RF power and the working pressure. The maximum PST film etch rate is 56.2 nm/min, because a small addition of $Cl_2$ to the $Cl_2/Ar$ mixture increased the chemical effect. It was proposed that sputter etching is the dominant etching mechanism while the contribution of chemical reaction is relatively low due to low volatility of etching products.

This study examines the effects of ISO 9001:2000 Quality Management System(QMS). Before accrediting it, it is affected by the top management leadership and corporate culture. After finishing the accreditation, some companies form quality culture, but some companies do not. That affects the corporate performance. If quality culture forms, companies performance will be good. But if not, companies performance will be bad. The accreditation of ISO QMS is not the end goal for the companies but forming the quality culture will enhance the corporate performance.

The long term stability of ion current of QMS has been one of key parameters for monitoring gas process in vacuum. The time dependence of ionic current was monitored while the pressure of nitrogen gas was kept at a fixed pressure by introducing the gas into vacuum chamber. The chamber was evacuated to ${\sim}3{\times}10^{-9}\;Torr$ to reduce background signals before the measurement. Two ion sources were tested; one had brownish or black color due to gas contamination and the other one was new, i.e. cleaner. At a nitrogen pressure of $1{\times}10^{-5}\;Torr$, the ionic currents measured by the contaminated ion source decreased faster with time. The decrease rate was respectively ${\sim}46%$ for cleaner one and ${\sim}84%$ for contaminated one after ${\sim}5.5%$ hours. In order to test the effect of filament material on the ion current decrease, we fabricated a tungsten(W) filament which consisted of two parts; one half was made of W and the other was coated with yttria. The similar decrease of ionic currents were shown for the two types of filaments, indicating that slight change of temperature of filament due to material difference i.e. baking effect could not improve the origin of ionic current decrease. Overall the decreasing rate of ionic current is more closely associated with contaminated ion source of QMS rather than its filament materials.

The objective of this research is to analyze the effects of quality management system constructed by ISO 9001 certificates through BSC perspectives. Evaluation of quality management system based on BSC framework can consider short-term financial performance as well as nonfinancial performance characteristics, which will derive future financial results. This results show that QMS has an indirect effect on business performance through quality performance and customer satisfaction, which are internal business process and customer perspective, rather than have direct effects on financial performance. Finally we suggest implications of this study and future research direction.
