This paper is aimed at proposing a new approach to connecting the measurements of customer satisfaction on healthcare services with the prioritized identification of healthcare service processes to be improved. As customers' requirements for healthcare services have become too diverse and healthcare service systems have been increasingly complex, there has been growing interest in the customer-oriented evaluation of healthcare service quality and the systematic improvement of healthcare service processes. Most of the previous studies on service quality evaluation are based on SERVQUAL model. However, because of the unique characteristics and constraints inherent in healthcare service systems, it has been reported that SERVQUAL would be inadequate to be applied to healthcare service systems. As an alternative, SERVPERF has recently been widely used in the evaluation of healthcare service quality. However, there is a lack of studies on how to use the measurements of healthcare service quality systematically to improve service functions and processes. With this issue in mind, we firstly measured the customer-perceived satisfaction on the healthcare service quality from the six dimensions based on SERVPERF. Then we identified the relationships between the subjective measurements and healthcare service processes through brainstorming and expert interview. By using the relationships, we developed a customer journey map in healthcare services that visually describe the interaction between customers and healthcare service systems. The developed customer journey map would help service designers easily identify a healthcare service process that needs to be improved with priority. It is expected that the design improvement process proposed in this study would be a useful method for enhancing the quality of healthcare services.

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.

지능형 서비스 로봇(Intelligent Service Robots)이란 스스로 주변 환경을 모니터링 하고, 문제 상황 발생시 해결 방안을 마련하여 사용자에게 적절한 서비스들을 제공해 주는 로봇을 말한다. 그러나 로봇이 접할 수 있는 다양한 환경과 상황, 문제들을 미리 예측하여 필요한 모든 기능들을 내부에 포함시키기는 어렵다. 로봇 내부에는 환경에 맞는 필요한 기능들만 가지도록 하고, 필요에 따라 새로운 기능들을 증식 시켜 줄 수 있는 자가 성장 소프트웨어(Self-Growing Software)를 개발함으로써 이러한 문제점을 해결할 수 있다. 본 논문은 자가성장 소프트웨어가 외부로부터 필요 기능 수행을 위한 서브아키텍처(컴포넌트의 조합 패턴)의 획득을 브로커를 통해 수행 할 때, 기능적인 측면뿐 아니라 품질특성과 환경을 고려하여 적절한 서브아키텍처를 선택하는 방법에 관한 것이다. 사용자의 품질 요구를 고려하여 기능수행에 가장 적합한 서브아키텍처를 추론하기 위해 사용품질요구(Quality-Attributes In Use) 온톨로지를 구축하였고, 컴포넌트 조합 선택을 위해 추상화된 레벨 선택 및 구체적 레벨 선택의 2단계 선택 기법을 개발하였다 추상화된 레벨에서는 상위단계 목표를 기반으로 서브아키텍처의 특성들을 추론하고, 구체적 레벨에서는 컴포넌트 자체의 사용품질요구에 부합하는 특성들을 기반으로 실제 서브아키텍처를 검색한다. 이러한 방법을 통해 사용자의 목표나 상황에 따라 달라지는 품질 요구사항을 반영하여 서비스를 제공할 수 있다. 또한, 로봇의 기능 증식 시에 사용자의 목표에 좀 더 부합하는 기능 선택이 가능하고, 사용자의 요구와 소프트웨어 기능 표현 및 해석상의 차이를 극복할 수 있다.

As growth of the web-based applications, the requirements of the users who have been very familiar to the web-based user interfaces and customer-oriented services on the Internet would become more knowledge-intensive and higher technology involved in a more convenient and polite way of service delivery. Therefore, the service quality of information system department should be considered as a very important factor influencing success of information systems. The objective of this study is to provide the relationship between service quality of IS department and its impacts such as use, user satisfaction and job performance. For this purpose, we provide a research model for it and test it empirically for the users of the corporate portal in one of main telecommunication service providers in Korea. In result, our model with satisfiable validity and reliability shows not only importance of IS departments' service quality but also two-faced characteristics of service quality. That is, while technical competence which means with knowledge and expertise of IS department staffs is more related with user satisfaction on information systems, personal service which means the way and manner of service delivery is more related with use of it.

This study examines the preliminary license and approval facilitation standards for improvements in quality for childcare centers focusing on the number of children, building space standards, facilities and equipment, and childcare program. Data from 48 caese was collected from childcare centers nationwide in Korea through a questionnaire and building plan. The first step for starting care licensing is to work out the ages and numbers of children within four or five age ranges. The second step is to work out the number of children as small, medium, or large considering staff to child ratios and building size. The Nnext step is to make a choice about childcare service quality classification as minimum, fair, or good, considering space requirements per child for the building, the classroom and the outdoor playground. The next step is to make a choice of space organization relating to service programs, considering the sleeping and eating area, indoor play area, toilet & washing facilities, classroom layouts such as cluster type, double zone type, single zone type, and others. Also, each room and entrance, office, kitchen, storage, laundry, teacher's area, and chilldren's area, need to be checked for space requirements and performances. The last step is to arrange the childcare program with the building and site plan. In conclusion childcare service quality will get better by upgrading of license regulation especially in minimum space requirements per child, corresponding with an increase in GNP and housing area per person. This is needed for childcare licensing in order to determine the quality level of childcare service.
