Recently the information system introduction and the application which use the computer are increasing. The efficient operation of information system helps corporations to improve productivity, customer service and corporate competitive power. SaaS(Software as a Service), which is the developed type of outsourcing in the area of information technology, is to use standardized and packaged application by hosting from the outside of enterprise. SaaS is not developed yet as much as people's interest about that in the initial stage, but its related technology and service capacity are accumulated after repeated trial and error, and it's ready to activate the industry. In the area of information system, studies on the measurement of service quality were followed. But there is little study on service quality measurement in the field of SaaS(Software as a Service). The purpose of this study was to divides the SaaS with e-SERVQUAL and it consider the relationship with the perceived recognition and the usage intention. According to this, variables of traditional research were rejected because SaaS is not developed yet in Korea. But information had a strong effect on perceived recognition. Therefore, business related with in SaaS must have provided a correct information about various applications.

In general, service failure occurs inevitably and the customers who experienced the greater dissatisfaction have the higher expectations of service recovery. However, most of the previous studies have focused on the evaluation and risk factors of pre-service quality. Thus, this study is contrary to the numerous previous studies and focus on the effectiveness of mobile application advertisement users' perceived perception on service recovery after service fails. A research model presented in this study is based on the Equity Theory and deeply evaluated the effectiveness of Distributive Justice, Interactional Justice, and Authenticity Relevance on Service Recovery. The survey of this study was conducted among 286 users who have experienced a services recovery of mobile application advertising. As a result, among all the factors of users of mobile application advertising, Distributive Justice, Interactive Justice, and Relevance have a positive impact to Satisfaction. In addition, Distributive Justice, Authenticity and Satisfaction also have a positive impact to Trust. Ultimately, Satisfaction and Trust have a positive impact to Service Recovery. The results of this study are expected as a reference for presenting a new business model for mobile application advertising industry, reducing business risk and enriching the related researches.

현재의 인터넷은 Best-Effort 서비스만을 지원한다. 그러나 지난 몇 년 동안 인터넷 환경의 지속적인 발전으로 인해 Best-Effort 서비스의 한계를 넘어선 새로운 형태의 Application들이 등장하게 되었고, 이러한 Application들은 end-to-end간에 QoS(Quality of Services)보장 및 보안을 요구한다. 본 논문에서는 IETF에서 제안한 QoS 보장 기술중 하나인 Differentiated Services를 이용하여 end-to-end 간의 QoS보장 및 IP Security 적용한 가상사설망(VPN) 구현방안에 관해 연구하였다.

활용 중심의 기록관리 환경에서 효율적인 기록정보서비스를 제공하는 것은 매우 중요해졌으며 더 나아가 제공하는 서비스의 품질에 대한 중요성도 증가하였다. 본 연구는 품질관리기법인 품질기능전개(QFD)를 국가기록원 기록정보서비스에 적용하여 그 개선방안을 제안하기 위한 사전 연구로, 국가기록원에서 제공하고 있는 기록정보서비스의 품질 차원을 분석, 구체적인 이용자 요구사항 항목을 도출하였다. 이를 통해 국가기록원 기록정보서비스 특성이 반영된 이용자 요구사항 설문지를 개발하였으며, QFD를 적용한 선행연구를 토대로 QFD 적용모형을 설계하였다. 본 연구에서 제안한 QFD 적용모형을 기반으로 QFD를 단계적으로 수행함에 따라 도출되는 결과는 HoQ로 표현될 수 있으며 이는 서비스 설계 시 기초자료로 활용할 수 있다.

본 연구는 레스토랑 산업에 널리 적용할 수 있는 외식 서비스 품질 측정을 위한 다문항 척도를 개발하였다. 척도 개발을 위해 Kelly Repertory Grid 방법을 이용하여 중요하게 생각하는 레스토랑 품질 속성을 파악한 후 전문가 토론을 수차례 거쳐 유사 중복 항목을 통합하고, 핵심 차원별 주요 속성을 도출하였다. 척도 정제를 위해 신뢰도 분석과 탐색적 요인 분석을 실시하였으며, 이후 각 구성 개념에 대한 중복성 여부를 확인하기 위하여 3차 확인 요인 분석을 실시하였다. 본 연구에서는 Brady & Cronin(2001)이 제안한 위계적 서비스 품질 모형을 바탕으로 외식 서비스 품질 척도를 개발하였다. 본 연구의 위계적 외식 서비스 품질 모형은 외식 서비스 품질 차원 및 측정 요인을 물리적 환경 품질, 상호 작용 품질, 음식 품질이라는 핵심 차원으로 설명함으로써 요인간의 중복성 완화, 결과와 과정 품질의 균형적 고려, 세 가지 핵심 차원별 관리포인트 명확화, 위계적 모형에 의한 핵심 차원과 하위 차원의 구분 등 이론적 기여 측면에서 뿐만 아니라 관리적 시사점 도출 측면에서도 우위성을 갖는다고 할 수 있다.

애플리케이션 아웃소싱의 새로운 형태로 등장하고 있는 ASP 모델은 정보시스템을 자체적으로 개발하여 운영할 인력과 전문성이 부족한 중소기업에 적합하다. 그러나 ASP 모델에 대한 연구는 부족한 실정이다. 서비스품질은 ASP 핵심성공요인 가운데 하나로 거론되고 있지만 아직 ASP 서비스 품질을 측정하기 위한 타당한 도구가 개발되지 않고 있다. 따라서 본 연구에서는 마케팅 분야에서 서비스품질을 측정하기 위한 도구로 개발된 SERVQUAL을 응용하여 ASP 서비스 품질 측정 모델을 개발하여 실증분석을 수행하였다. 본 연구의 표본은 "소기업 네트워크화 사업"에 참여하고 있는 소기업 가운데 무작위로 300개 기업을 선정하여 방문조사를 통해 240개의 설문지를 수거했다. 그리고 이러한 조사자료를 분석한 결과 신뢰성과 유형성은 다른 어떤 서비스품질 구성요인보다도 사용자 개인성과 및 만족도에 유의한 영향을 미치는 것으로 나타났다.

In this paper the authors presents a new method, named FR-SERVQUAL, of evaluating perceived service quality in Public Sectors, using triangle fuzzy numbers and semantic differential scale. By conventional quantification methods, it is not easy to express the notion of a linguistic variables and customers' subjective judgements. In contrast to the conventional PZB methods which express the customers' perception of quality as a function of gap between the expected and perceived service, this paper suggests to use the ratio of the two. Through an application example, this paper shows that the current FR-SERVQUAL approach provides a more realistic way of measuring service quality compared to existing methods.

Recently, the number of smartphone users has skyrocketed because of a plenty of useful services that smartphone applications provide. In the Information Systems (IS) literature, however, there has been little understanding about the effects of the service quality of smatphone applications on user satisfaction and loyalty. Thereby, this study examined 1) the effects of the service quality of smartphone applications on users beliefs, perceived usefulness and easiness and 2) the effects of the user beliefs as mediating variables on users' attitude, satisfaction, and loyalty. A survey was conducted and SEM was employed to analyze the data. The results showed that the service quality of smartphone applications affect users' attitude, satisfaction, and loyalty through the mediating variables.

The increase in the number of smartphone users has recently been steep, which started to offer companies and individuals more opportunities to enter into a new business field. Furthermore, the smartphone applications have become one of the hottest topics inside and outside the mobile industry. Still the market is in its infancy and intention to pay of charged application of most smartphone users is relatively low. However, rate of charged application in appstore is expected to be increase steadily for some years to come. In this perspective, it is important to consider the smartphone mobile application. Research on smartphone application is still in its early stage. Thus, the purpose of this study is to find what are the effective factors on user satisfaction and intention to pay of mobile application. Based on information system success model, we proposed system quality(stability, usability, security), information quality(timeliness, accuracy, enjoyment) and service quality(reactivity, reliability, empathy) as factors to effect on user satisfaction in mobile application. The results showed that stability, usability, timeliness, accuracy, enjoyment, reactivity and empathy affected significantly user satisfaction. The relationship among satisfaction and intention to pay of mobile application was significantly supported. The implications of the findings is that firms and individual developers of mobile application should focus on customer retention through enhancing satisfaction and quality.

Achieving situation awareness is especially challenging for real-time data stream applications because they i) operate on continuous unbounded streams of data, and ii) have inherent realtime requirements. In this paper we showed how formal data stream modeling and analysis can be used to better understand stream behavior, evaluate query costs, and improve application performance. We used MEDAL, a formal specification language based on Petri nets, to model the data stream queries and the quality-of-service management mechanisms of RT-STREAM, a prototype system for data stream management. MEDAL's ability to combine query logic and data admission control in one model allows us to design a single comprehensive model of the system. This model can be used to perform a large set of analyses to help improve the application's performance and quality of service.
