  • In this paper, we introduce Quality of Service(QoS) analytic model of a distributed system that decentralizes the process nodes performing each task and communicates through a network for cooperation. The model advances a service reliability model of Dai et a1.(2003) by means of considering the processing time. The service is assumed to be provided by a centralized heterogeneous distributed system which is composed of some subsystems managed by a control center. The QoS is defined as the probability that a service is provided successfully in an allowed time, we consider the hardware/software reliability and the processing time which include program execution time, data transfer time. We derive the processing time distribution for a required service through convolution of corresponding probability density function. An application example is used to explain the procedure of computing quality of service.

  • ISO/IEC 9000에 의하면 품질이란 사용 시 사용자 요구사항을 만족시키는 제품이나 서비스의 특성을 종합한 개념으로 정의하고 있다. 웹애플리케이션의 시큐어코딩은 안정성과 함께 정보시스템 서비스 품질을 결정짓는 요소 중의 하나이다. 시큐어코딩을 달성하기 위해서는 품질을 기반으로 하는 설계 모델이 필요하다. 그 이유는 보안도 하나의 품질 속성으로서 비 기능적 요구사항의 범위에 속하기 때문이다. 웹애플리케이션 품질평가체계 설계를 위해서는 품질의 정의를 기초로 품질속성, 품질요구사항, 품질측정 시나리오가 정의되고 설정되어야 한다. 이를 위해 IEEE 1061 품질모델을 참조한 웹애플리케이션 품질모델 관리체계를 개발한다. 웹 애플리케이션 아키텍쳐 설계는 시큐어코딩 품질모델 체계, 웹어플리케이션 이해관계자 관심 도출, 아키텍처 동인 결정, 품질속성 도출, 보안품질 요구사항 설정, 웹어플리케이션 아키텍처기술서 작성, 보안 프레임워크 설계 순서로 구성된다.

  • The subject of this study is user experience analysis for OTT mobile app services. Application service quality was quantitatively measured by utilizing KS-eSQI evaluation model from a service quality perspective. The purpose of this analysis is to analyze how service reuse and other people's intention to recommend services are affected by service quality. In addition, further analysis of user experience will qualitatively look at what efforts are needed to improve OTT service quality and provide a user-friendly environment. According to the survey, the higher the level of KS-eSQI service quality, the higher the reuse of OTT services and recommendation of others. In particular, the dimensions of primary services and unexpected additional services had a higher impact on customer loyalty and recommendation of others than in other industries. Moreover, the following three implications were found to improve app services from a customer experience perspective. First, images and video thumbnails that highlight the strength of the content they provide should be actively utilized. Second, it is necessary to provide service companies with evidence for data-based work recommendations. Third, it should provide a viewing environment in which users can respond more intelligently to the various situations and conditions when they actually watch.
