Objective: The aim of this study is to present a solution to problems in the services provided by the general hospitals by creating a user-centric environment through analyzing the User Journey Map and the User Context. Background: The rapid growth in aging population and the monopolization of superior medical staffs by the general hospitals increased demand for the general hospitals in Korea. But, often services provided by the general hospitals are provider-centric and low quality. Method: This study examines problems in the services provided by the general hospitals by analyzing the User Journey Map through stakeholder interviews(contextual interviews) and on-site observation. Based on the contextual analysis of the user(i.e. the patient), this study proposes new and improved user-centric services to be provided by the general hospitals. Results: Ten new user-centric services proposed by this study are: (1) "Booklet on Success Story", (2) "FAQs by Doctor", (3) "Designated Nurse", (4) "Patient Interview Record Card", (5) "Close relationship between doctor & patient", (6) "Thank You Notice Board", (7) "Step by Step", (8) "Green Cap", (9) "Patient Kit", (10) "RFID Direction Display System". Conclusion: The service design for the general hospitals proposed by this study is an important case-study on improving the environment of the general hospitals from provider(medical staffs)-centric to user(patents and its family)-centric. Application: This study is expected to be used in various areas to improve existing system(products and/or services) to be more user-centric.

The purpose of this study was to assess the user's satisfaction of health care service in public health centers in Busan. The study respondents were 212, those who visited health centers for health care service. Data were collected in July 2002 by using SERVQUAL(comprehensive service quality measurement scale) and 3 open questions for more details about service satisfaction and the needs for health care service. SERVQUAL has 5 dimensions； tangibles, reliability, responsiveness, assurance and empathy. The results were as follows ： 1. The users reported more satisfaction at 'just service cost', 'convenient service procedure' and 'clean physical environment' at SERVQUAL. Among them the highest rated item was 'service cost'. And the less satisfaction items were 'understanding and individual concerns about service users', 'medical equipment' and 'health center facilities'. 2. There were no statistical differences by general characteristics except for the kind of services rendered. Those who visited for physical examinations and laboratory tests reported lower satisfaction than any other groups. 3. At the open questions, the respondents expressed that they were satisfied with the low service cost, kindness of employee and clean environment. But they criticized the old facilities and worn medical equipment, in addition to the less than kind attitudes. These strengths and weaknesses of health center's service could be applied for planning of customer­centered health care service.

Efforts to build metaverse platform services and expand profit structure are developing in a more realistic direction. The metaverse, which has been centered on 'creation and economy' and 'discovery', will evolve into an 'experience' metaverse, creating tangible business effects where satisfaction with the user experience leads directly to purchase. In this paper, the condition of the avatar used as a medium of economic activity between the metaverse platformer and the user and the business utilization plan were sought. In addition, a new 'metaverse business model' was proposed based on 'experience, discovery, creation and economy', and in particular, it was intended to lay the foundation for the experience metaverse to further develop in the form of 'business experience'. In addition, a survey was conducted on the 'application of metaverse service and avatar' targeting the MZ generation, the main customer base of the current metaverse service. In order to provide a service that satisfies the user, it was concluded that the appearance of the avatar needs to be changed according to the purpose and function. Accordingly, we propose an 'selective switch mode' that can change the avatar's appearance at the desired timing according to the 'experience' and 'purchase purpose' of each metaverse service area. In addition, by strategically utilizing the 'Digilog' psychology, we believe that it will be possible to promote the influx of new users while increasing the loyalty of existing users to the platform. Through the establishment of 'avatar purchase system' by 'selective switch mode' and 'avatar decorating system' by 'digilog' strategy, the experience metaverse, which has been focused on 'digital twin experience' so far, is As it develops into 'business experience', it is expected that the user experience can be further satisfied.

Free viewpoint video (FVV) service is an immersive media service that allows a user to watch it from a desired location or viewpoint. It is composed of various forms according to the direction of the viewpoint of the provided video, and includes zoom in/out in the service. As consumers' demand for active watching is increasing, the importance of FVV services is expected to grow gradually. However, additional considerations are needed to seamlessly stream FVV service. FVV includes a plurality of videos, video changes may occur frequently due to movement of the viewpoint. Frequent occurrence of video switching or re-request another video can cause service delay and it also can lower user's quality of service (QoS). In this case, we assumed that if a video showing an object that the user wants to watch is selected and provided, it is highly likely to meet the needs of the viewer. In particular, it is important to provide an object-oriented FVV service when zooming in. When video zooming in in the usual way, it cannot be guaranteed to zoom in around the object. Zoom function does not consider about video viewing. It only considers the viewing screen size and it crop the video view as fixed screen location. To solve this problem, we propose a zoom in/out method of object-centered dynamic adaptive streaming of FVV in this paper. Through the method proposed in this paper, users can enjoy the optimal video service because they are provided with the desired object-based video.

This study intended to analyze whether the system of voucher system, which was introduced as a policy tool to expand social services, was dependent or evolving through the research methodology of historical institutionalism. The voucher system is being introduced to emphasize the user's focus in the existing supplier-centered service provision system, but problems with the existing system have been found so far. We found that despite the shift in welfare paradigm from the remaining welfare supply to universal welfare in the past, the company was partially following the existing supplier-centered social service system. However, We found that new instruments for establishing legal systems and the path evolution factors are now being developed and matured within the voucher system. In other words, it was possible to predict that the voucher system would become more positive and mature in the future through logical changes in the system. Based on the results of the analysis of the voucher system, policy suggestions for policy values and objectives that were initially oriented toward the system were presented.

Web casting has become an important opportunity to apply the user-centered concept to broadcasting because it provides real-time interactive service through time and space. It is also necessary to have a new understanding about user who is not a passive viewer any more but an active user. The amount and quality of contents are also important, but usability is a competitive factor as well as the fundamental customer services that have user best experience at the site. Nevertheless most of web casting sites show the low level of usability. In this study we had a comparative evaluation among these sites, MBC, KBS and SBS, which are the representative broadcasting systems. The tests were carried out as heuristic evaluation and usability testing. We analyzed causes and problems of web usability for customer satisfaction and reliability exaltation, and expected the basic knowledge of developing and improving sites.
