Client(patient) satisfaction has been used for a variety of purposes in different settings, yet, those receiving home care services have been the focus of few satisfaction studies. Satisfaction is considered an indicator of quality of care and is also being used to assess the performance of home care providers and home health care delivery at multiple levels. The aim of this study was to develop the tool for evaluating client satisfaction in several aspects with home care service while maintaining or achieving acceptable reliability and validity. Firstly, Client Satisfaction Instrument made preliminary of 43 items composed basic 6 criteria and 7 indicators, based on a review of literature, quality improvement and client satisfaction findings in home care. Secondly, there were consisted in two expert panel groups who were made in professionals of research and practice in home care field. The tool was modified to 6 criteria and 7 indicators, 25 items after reviewing by two expert panel groups. The content validity index of the tool was above 0.8 and the results of internal consistency was more than 0.8 in all items. Finally. The Client Satisfaction Instrument in Home Care Service was made up 6 criteria such as client satisfaction of nurses's instruction of home care educational need. knowledge/technique/attitude of homecare nurses's performance. interpersonal relationship and emotional support of nurse. easiness of homecare accessibility, continuity of homecare service. overall efficacy of homecare use, 7 indicators. and 25 items. The results of evaluating client satisfaction will be able to contribute in quality improvement and service marketing in home care.

In the field of computing service, there is a copernican revolution indebted to development of network & computer technology. Computer system, which is set to mainframe in the 1960's, is advancing torwards to the paradigm of server based computing, so-called thin-client. In thin-client computing, network is the platform which is responsible for transfer of application, so that client execute application installed on server. It is also possible that each system share the computing resource connected with network. In this parer, we suggest component & distributed computing technology as a measn for the implementation of thin-client architecture hence, make the best use of COM(Component Object Model and PYRO(PYthon Remote Objects). We talk about the concept and mechanism of thin-client at the beginning, and propose the design of network architecture for the implementation thin-client.

How to transfer spatial data from server to client in wireless broadcasting environment is shown as following: A server arranges data information that client wants and transfers data by one-dimensional array for broadcasting cycle. Client listens data transferred by the server and returns resulted value only to server. Recently number of users using location-based services is increasing alongside number of objects, and data volume is changing into large amount. Large volume of data in wireless broadcasting environment may increase query time of client. Therefore, we propose Client based Data Scheduling (CDS) for efficient data scheduling in wireless broadcasting environment. CDS divides map and then calculates total sum of objects for each grid by considering number of objects and data size within divided grids. It carries out data scheduling by applying hot-cold method considering total data size of objects for each grid and number of client. It's proved that CDS reduces average query processing time for client compared to existing method.

Credit cards are more convenient than cash of heavy. Therefore, credit cards are used widely in on_line (internet) and off_line in nowadays. To use credit cards on internet is commonly secure because client identification based security card and authentication certificate. However, to use in off_line as like shop, store, department, restaurant is unsecure because of irregular accident. As client identification is not used in off_line use of credit cards, the irregular use of counterfeit, stolen and lost card have been increasing in number recently. Therefore, client identification is urgently necessary for secure card using in off_line. And the method of client identification must be simple, don't take long time, convenient for client, card affiliate and card company. In this paper, we study a reform measure of the structure and transaction process for the safety improvement of a credit cards. And we propose several authentication method of short-and long-term for client identification. In the proposal, the client authentication method by OTP application of smart-phone is efficient nowadays.

To improve the security of OAuth 2.0 access token transportation and satisfy the challenge of resources constraint caused by the bearer token access mechanism of the OAuth 2.0, we proposed an extensional client authentication scheme that is based on the Proof-of-Possession (PoP) token mechanism. By improving the integrity of PoP token, we bind a PoP key of a public/private key pair to the PoP token. The authorization server and the resource server can authenticate the identity of the client by verifying whether the client has the possession of the PoP token. If the client can prove that it has a PoP key that matches the PoP token, then the identity of the client can be authenticated. This experimental evaluation can confirm that this scheme effectively dealing with the issue of client identity authentication and reduce resources consumption.

From the perspective of the client, the value of information for use in facility management is very low at the point of use. This is because the facility owner, who is a non-professional, cannot accurately request necessary information from the perspective of long-term facility life cycle management. The purpose of this study is to define the information necessary for facility management and to analyze the project operation method to procur this information to the client using BIM. To this end, this study analyzed the role of client and contractor, project delivery process, standards, and submissions in the BIM-based procurement area through USACE Air Force Hospital project case analysis. As a result of the analysis, if the client, who is the subject of facility operation, defines in advance the type and input method of necessary information in the operation stage, the client can receive the BIM optimized for operation from the contractor. The results of this study can be used to establish standards for receiving information necessary for establishment of procurement process and facility management of public institutions considering BIM introduction.

Client requirements is a concept with increasing interest in relation to several outcomes of companies, and in particular, in the event of apartment project that takes large share in the domestic construction industry, diverse angle of survey is performed to discover the client requirements and reflect them to the project to improve the quality. For this purpose, it is required to learn the client requirements and apply it in the apartment project, and the QFD (Quality Function Deployment) linked ROQ (Return On Quality) is a technique used in the manufacturing that surveys the client requirements to improve the customer satisfaction, and apply it to the quality improvement program to improve the profitability in this process. In this study, through the application of the ROQ process, the plan to improve the apartment quality management is presented. For this purpose, the consumer interview survey, FGI (focus group interview) survey and the client requirements are analyzed, and thereafter, through the interview with the specialist, the quality improvement program that enables the application to the product development of new apartment product is established. Through this process, the new apartment quality management improvement plan is presented.

본 연구에서는 Web 환경에서 분산객체 기술인 CORBA(Common Object Request Broker Architecture)를 이용하여 Java Applet으로 구현되는 의료영상회의 시스템의 Web Client를 설계 구현하였다. 플랫폼(platform)에 독립적이고, 다양한 개발 언어를 지원하는 CORBA를 기반으로 한 이 의료영상회의 시스템은 시스템의 개발, 확장성 및 유지 보수 측면에서 아주 뛰어나다. 또한 객체 지향언어이면서 다양한 플랫폼에 구애를 받지 않는(Architecture Neutral) Java 언어를 이용하여 Web 환경에서 쉽게 실행 가능한 Applet으로 의료영상회의를 할 수 있는 Web Client를 설계 구현하였으므로 Web 브라우저를 이용할 수 있는 환경이라면 손쉽게 이용할 수 있는 장점을 가진다.

최근, 인터넷 사용자가 급증하면서 빠른 서비스에 대한 문제가 큰 관심이 되고있다. 특히 데이터베이스 시스템에서 저장 삭세 수정 등은 사용자에게 긴 대기시간을 요구할 수도 있기 때문에 사용자의 불평을 야기할 수 있다. 이 논문에서는 3-티어 방식에서 요즘 많이 사용되는 application server의 cache에 대해서 말하고자 한다. 기존 application server는 데이터를 application server cache에 저장하여 같은 데이터를 서비스할 경우 server의 cache를 사용하지만 이 논문에서 제안하는 것은 접속된 client를 관리하여 각각의 client에 cache를 만들고 application server나 또는 데이터베이스 server가 서비스를 하지 못할 경우는 가장 최근의 데이터를 가지고 있는 client를 찾아 client cache에 있는 데이터를 서비스 하자는 것이다.
