The papaer reviews four theoretical acceptance sampling plans as OC(Operating Characteristics) curve based inspection, rectifying inspection, switching inspection, and continuous inspection. In addition, the study presents practical limitations of theoretical acceptance sampling by attribute and by variable. Finally, following research also recommends the sampling inspection based on production technology. However, the inspection method requires quality expertise with various experience and implicit knowledge of the field.

Generally, Fixed Quantity ordering system (Q-system) uses linear model in inventory decrease. This paper focuses on that Fixed Quantity ordering system (Q-system) is based on a continuous review system. To use a continuous review system is because of an inventory decrease ration is not constant. Therefore, this paper introduces a method to select a model which is proper to virtual data under conditions which are inconstant.

For the unconfined vapor cloud explosion accident by the continuous release of gas-liquid flow of various saturated liquids in a vessel at ground level, overpressures were estimated and analyzed with various release conditions and materials by TNT equivalency model with vapor dispersion. We found that at same release conditions, overpressure showed n-heptane > xylene > n-hexane > toluene > n-heptane > benzene, respectively and that overpressure was increased with increasing the hole diameter and the storage pressure, but it was increased with decreasing the wind speed, the interested distance, and the vessel thickness.

The paper aims to apply a model of continuous quality improvement (CQI) to Taiwan provincial Pin Ton hospital. Tools of quality control were used both total quality management (TQM) and quality control circle (QCC) in order to approach the objective of ${\ulcorner}$higher quality, higher efficiency, lower cost${\lrcorner}$. During two years, this hospital has organized thirteen QC circles that were classified three categories according to that objective: four circles work for higher quality; the other four circles work for higher efficiency; five circles for lower cost. After implementation, several results were found from two viewpoints. From viewpoint of tangibility, one of the most outcomes is to reduce labor cost from 56 persons to 28 persons of temporary employees. From viewpoint of intangibility, the result was evaluated using radar chart to compare the difference after improvement. This paper is going to report the process of CQI for the hospital management because it is a new issue in Taiwan since 1997

This study demonstrates some major traits of digital contents as information, playfulness, individuality, as satisfaction and commitment, user behavior as use intention. To make an empirical analysis the study, it is hypothesized that traits of digital contents, relationship quality, and user behavior. The major finding of this study can be summarized as follows, traits of digital contents are positively affected by satisfaction in relationship quality and use intention. Theoretical implication of this study are as follows. First, users wanted to choice only needed information. Second, users recognized digital contents as a part of life. So, user's ability is very important in this environment. According to this, business related with or interested in digital contents must have developed digital contents in variety aspect. Users must have concerned using digital contents, also.

In this study, we propose trajectory-based arrival management using CDO (Continuos Descent Operations). The operational procedures with TBO (Trajectory-Based Operations) concept were established to allow aircraft and ground system to share the trajectories with each other in real time. The proposed operational concept was validated in the air traffic control simulation environment, which consists of controller working position, pseudo pilot system, air traffic generation system, and controllers' decision support system for arrival management using CDO. Simulation results compared with actual flight data indicate that proposed concept could improve the efficiency of traffic flow management in terms of total descending time and fuel consumption. And it was confirmed that if there is a system that can share and utilize the synchronized trajectory, it can be helpful to control arrival aircraft and apply CDO concept.

In order to provide continuous Korea Augmentation Satellite System (KASS) services, the operation organization should continuously and systematically perform operations, maintenance, and technical activities. All subsystems of KASS, all Line Replacement Units (LRUs), and Software Replacement Units (SWRUs) should be operated and maintained continuously. In order to effectively manage these activities, it is necessary to develop an Operation Management Tool (OMT). For this purpose, operation management, operation organization, and operation activities were defined. The defined requirements were divided into general, function, interface, and database for OMT development, and functions and decision-making procedures consisting of site/asset/trouble/work order/schedule management were designed. The OMT developed by reflecting the site and asset information as well as the design content met predefined requirements. The OMT will be actively used in actual KASS operation and will evolve by continuously reflecting the additional requirements of operators. Through this tool, KASS will support continuous service provision.

Purpose: The purpose of this study was to explore the self management and related factors that affect the self management of diabetes between the middle aged and elderly groups. Method: This study was based by the conceptual framework of Cox's interaction model of client health behavior. The subjects were two groups; the middle aged group, 80 and the elderly group, 85 who were diabetes mellitus patients. Result: In the middle aged group, gender, education and social support were significantly correlated with self-management of diabetes mellitus. In the elderly group, gender, education, social support and the duration of diagnosis were significantly correlated with self-management of diabetes mellitus. In too middle aged group, the intrinsic motivation of diabetes mellitus patients and their understanding of diabetes were significantly correlated with self-management of diabetes mellitus. Understanding of diabetes and self perception were significantly correlated with self-management in middle aged group. In the elderly group, intrinsic motivation, understanding of diabetes and the attitude of the patients were significantly correlated with self-management Conclusion: In the middle aged group, maintaining a positive attitude of diabetes, reducing stress and continuous social support were important for improving self-management of diabetes mellitus. In the elderly group, enhancing their knowledge of diabetes, and maintaining continuous social support were important to improve self-management of diabetes mellitus.

특정 보안 기술만으로는 나날이 치밀해지는 공격을 방어할 수 없기 때문에 ISMS(Information Security Management System) 등 다양한 보안관리 모델 등이 적용되고 있지만, 너무 많은 항목에 대한 일반적인 보안관리 방안을 제시하고 있어 취약점이 높은 부분에 집중하지 못하는 단점이 있다. 최근 수년간 우리 사회에 막대한 피해를 입힌 주요 정보 및 기밀 유출 관련 사건을 분석한 결과, 공격자는 주로 이메일, 웹 서버, 휴대용 저장매체, 외주업체 직원 등 조직의 내부와 외부를 연결해주는 통로인 '인터페이스(interface)' 취약점을 이용하였음을 발견하였다. 이를 통해 우리는 보안에 투자해야 할 시간과 자원이 제한되는 현실을 고려하여 공격자가 악용할 가능성이 높은 인터페이스에 대한 현재 보안 실태를 적시한 후 관리적 기술적 물리적 측면을 융합한 보안대책을 제시하고, 해당 인터페이스에 대한 중점적이고 지속적인 관리(continuous management)를 통해 투자 비용 대비 효과적으로 조직의 실시간 보안관리를 가능하게 하는 체계를 제안하고자 한다.

6시그마는 지난 20여 년간 제조 및 서비스 등의 산업에서 프로세스 개선을 위하여 꾸준히 적용되어왔다. 그럼에도 불구하고 6시그마는 Define 단계에서 의미있는 프로젝트를 계속 발굴하기 힘들고 Control 단계에서 지속적인 측정 및 통제가 쉽지 않다는 문제가 지적되었다. 이를 해결하기 위하여 개선 프로세스의 지속적인 통제와 관리를 원활히 할 수 있는 체계가 요구되며, 비즈니스 프로세스 관리(BPM) 시스템이 효과적 대안이 될 수 있다. 본 연구에서는 프로세스 운영 및 분석에서 누적된 데이터를 중심으로 지속적 프로세스 개선을 실현하기 위한 목적으로 6시그마와 BPM의 통합 모형을 제시하고, 프로젝트 수행을 위하여 상호 데이터기반으로 프로세스를 분석, 개선, 모니터링하는 과정을 설명한다. 이를 통하여 6시그마와 BPM의 장점을 결합하여, 지속적으로 업무를 개선하고 관리함으로써 전사적인 경영성과를 극대화할 수 있을 것으로 기대한다.
