The time to market and productivity of embedded system needs a quality measurement process management of embedded software. But, defect management without preemptive analysis or prediction is not useful for quality measurement process management. This subject is focused on the defect that is one of the most important attributes of software measure in the process. Defining of defect attribute and quality measurement process management is according to understanding of embedded sw characteristics and defect data. So, this study contributes to propose the good method of the quantitative based on defect management in the test phase of sw lifecycle.

In this paper, we propose video quality control system(VQCS) which can control video service quality through the monitoring of end-to-end available bandwidth for video streaming service like IPTV in NGN convergence network. Various multimedia services such as video, voice and gaming service can be provided by IPTV, and these services require large amounts of bandwidth. At this time, video quality degradation like video jerkiness, block distortion and blurring is caused when network available bandwidth is insufficient. Available bandwidth monitoring method is need to stably control video streaming quality. So, we periodically calculate the amount of the packets in link and measure available bandwidth by using total length field in IP header at terminal. Scalability extractor in network selects suitable video streaming data rate based on available bandwidth and transports video streaming with adaptive data rate to prevent video quality deterioration.

Today, as the number of applicants for admission decreases, competition among universities is deepening in Korea. Especially, the existence of local universities has led to intense competition to increase the enrollment rate of new students and reduce dropout rate. To survive in this competition, local universities are making various efforts; however, the primary problem is improving their educational service quality. In this study, we have developed a device to measure educational service quality which can be applied to the field of higher education, and factors that determine educational service quality are dragged through this device. In addition, this research identifies which statistically significant factors play a part in overall satisfaction and word of mouth effect, and interprets 29 quality attributes using importance-satisfaction transformed index.

취업박람회에서 참관객에게 제공되고 있는 박람회의 서비스품질, 가치, 그리고 만족 등의 이론적 배경을 바탕으로 인과관계를 나타내는 구조적 관계를 분석하였다. 개최 도시의 지각된 품질 요인은 정보의 확신성, 인적서비스, 접근성, 물리적 환경 그리고 관광매력성의 총 5개의 요인으로 총 16개의 항목을 Likert 5점 척도로 측정하였으며, 변수들의 집중 타당도와 판별 타당도를 확보하였다. 분석결과 관광매력성, 물리적환경, 인적서비스, 정보의 확신성 순으로 취업박람회 참가자의 지각된 가치에 영향을 미치는 것으로 나타났다. 이러한 연구결과는 박람회 주최자가 사용자 관점에서 좀 더 효율적으로 행사를 준비함과 동시에 참가 업체의 보다 나은 서비스 지원으로 기업의 가치인식 제고에도 기여할 것으로 기대된다.

This research was conducted to measure the satisfaction level of users and the service quality of specialized libraries in the digital environment. 289 users of 24 government-funded institutes were divided into humanity/social science area and science/technology area for comparison. Using seven hypotheses, the tests were conducted between three independent variables, service quality, space quality, and information quality and one dependent variable, user satisfaction. It was concluded that the competence and quality of the librarian, library homepage, and quality of information are most critical for user satisfaction. Suggestions are made: an improvement in the service quality and specialization of the librarian's skills, a need for librarian's courtesy education, a provision of differentiated and specialized quality of information, an easy access to the library homepage, and supports on the contents and information search.

This paper developes a multiple-item scale instrument (called SHIPQUAL which is designed to measure the quality of shipping industry. The procedures of developing instrument were followed by recommendations on the developing measures of marketing constructs. We divided shipping service quality into 4 demensions (reliability, conformability, timely/completness, safety) by empirical study. These demensions and scales were varified through the assessment of reliability and validity. Finally, we suggested potential applications of the scale into the shipping industry.

The present method of measuring QoE (Quality of Experience) was to measure the whole block from the server that provides service to the terminal that the client gets the service. In this way, it was possible to simply determine whether the quality of QoE was good or not, and when the quality of QoE became bad, there was no way of presenting solutions. Also, as QoE metrics are numerous, there has been no strict regulation on how to use. This study analyzed QoE metrics in the viewpoints of network and clients, subdivided the whole service into three phases including one from the server providing the service to the router, another from the router to the terminal getting the service, and the third from the service router to the client router, and presented QoE metric frames appropriate for each phase. Through this, in the KOREN-CERNET environment, this study designed and embodied QoE network and demonstrated stability of QoE network, reduction in client complaint settlement time, and content adjustment effect according to the network change.

This paper examined the relationships of service quality with customer satisfaction, and investigated the effects of trust and commitment. Data were collected from 242 people at hotel located in Taegu city. LISREL provided satisfactory model-fits in measurement model and structural equation model. The empirical results indicated that first, service quality takes strong effect on customer satisfaction and trust but not on commitment. Second, trust and commitment are importantly influenced by customer satisfaction. Third, service quality was found to indirectly contribute to trust and commitment. Finally, customer satisfaction is effective mediators linking service quality to trust and commitment.

We propose that service qualities (tangibility, assurance, responsiveness, empathy, reliability) affect customer satisfaction of instant messenger service, customer satisfactions do customer loyalty. As moderating factors of the relationship between customer satisfaction and customer loyalty, switching costs are suggested. To accomplish the object of this study data are collected from instant messenger user by survey research. We analyse the research model using structural equation model and moderated multiple regression. The result are as follows: (1) tangibility and responsiveness affect customer satisfaction. (2) customer satisfaction affects customer loyalty. (3) switching costs moderated the relationship between customer satisfaction and customer loyalty.
