Purposes: The objective of this study is to analyze service design process of dental clinic preventive service by using 'Double Diamond Design Process' which is user-centered for improving dental clinic management efficiency. Methodology: We examine case study that dental clinic preventive service of local dental clinic. Following the double diamond design four steps(①discover, ②define, ③develop, ④deliver), we use suitable analytic tools in each steps. In discover step, we perform observation and desk research. Next, in define step, affinity diagram, user persona, and user journey map are performed. We then make service blueprint in develop step. Finally, in deliver step, virtual scenario and confirm some outputs which are based on results of former steps are suggested. Findings: As a result of this study, waiting and consulting phases turn out that these phases are in the most trouble than others. Users(patients) have lots of complain and dissatisfaction in these phases. These touch-points will have to be modified Practical Implication: After checking this study result, it could suggest improvement schemes. To apply these, we try to make some scenarios, and finally realize some outputs. Service design has arisen to strengthen the competitiveness by reflecting user's experience and needs. Especially, service design is not typical, it is so flexible that can apply to various situation and objects. We hope that result of this study is made good use for dental clinics in need.

근래에 들어 제품개발에 있어 사용자를 최우선에 놓아 디자인하려는 사용자 중심 디자인에 대한 연구가 활발해지면서 사용자 관찰법(user observation), 사용성 평가(usability testing) 등과 간은 다양한 방법이 활용되고 있다. 하지만 이러한 방법들은 아직 사용자 중심 디자인 을 위해 효과적으로 활용되기 어려운 실정이다. 이에 대한 이유는 여러 가지를 들 수 있으 나 우선 이들 방법의 활용시, 특히 수집된 데이터의 분석과 저장시 소요되는 많은 불필요한 노력과 시간이다. 다음으로 이들 각 방법들은 제품개발의 어떤 특정 단계만의 활용을 위해 개발되었기 때문에 전체적 개발 프로세스의 관점에서 상호 유기적으로 잘 연결되지 못한다는 문제가 있게 된다. 이에 본 연구는 제품개발 전 과정에 걸쳐 활용될 수 있는 사용자 중심 디자인 방법을 살펴보고 이들에 적용될 수 있는 통합적 컴퓨터 지원 시스템을 개발하는 것을 그 목적으로 하고 있다. 제품개발 프로세스를 사용자의 니즈 분석단계, 인터렉션 디자인을 위한 아이디어 도출단계, 컨셉의 개발단계, 제품의 사용성 평가단계로 나누고 이들 각단계 에 요구되는 각 방법들의 특성을 파악하여 컴퓨터 응용방법의 기본 프레임웍을 제시한다.

In this paper, we present a signal analysis workstation in which the user can scrutinize and quantify biological signals, observe the effects of various signal processing algorithms on them, and eventually get some interpretation of clinical use. Within the system, the user can also access all the information in the central data base, such as patient personal information, biological signal information, and insert his interpretation results obtained into the data base after his careful observation. The software system is designed in an object-oriented paradigm, and written in C++ as a window-based application program.

This study examined user experiences of motion-based games. Focusing on the playing experiences, in-depth interviews and survey were conducted on seven families with various family members detailing the gameplay. These qualitative methods were conducted interpretive way such as a month-long participant observation. As a result, the game Sensible meantime, the results were excluded from the game with the older generation of women and the elderly, leading to game culture game is trying to communicate was confirmed.

주거환경의 변화는 주거공간을 구성하고 있는 제품을 더 이상 독립된 구조가 아닌 서로 네트워크로 연결된 하나의 제품 및 서비스로 인식될 필요성을 나타내고 있다. 따라서, 제품 및 서비스 컨셉 도출을 위한 사용자 조사 단계에서 사용자의 행위 관찰 시, 관찰의 범위가 기존의 개별 제품을 사용하는 환경 중심에서 전체 제품을 사용하는 환경으로 확장 될 필요가 있다. 본 연구에서는 주거공간에서 제품 사용의 관찰범위를 개별제품사용환경과 전체제품사용환경으로 분류하여 각각의 관찰범위에서의 사용자 행위 분석 데이터가 어떠한 차이를 갖는지 관찰법(Ethnography)을 이용한 사례연구를 통해 비교 분석하였다. 본 연구의 결과는 추후 주거환경을 구성하는 제품 및 서비스 개발 시 목적에 적합한 관찰범위를 선택하는데 있어 도움이 될 것이며, 기반이 되는 자료로 활용될 수 있을 것이다.

Multicast has communication mechanism that is able to transfer voice, video for only the specific user group. As compared to unicast, multicast is more susceptive to attack such as masquerading, malicious replay, denial of service, repudiation and traffic observation, because of the multicast has much more communication links than unicast communication. Multicast-specific security threats can affect not only a group's receivers, but a potentially large proportion of the internet. In this paper, we proposed the multicast security model that is able to secure multi-group communication in CBT(Core Based Tree), which is multicast routing. And designed the multicast key distribution protocol that can offer authentication, user privacy using core (be does as Authentication Server) in the proposed model.

This study researched that the remodeling was executed desirably in the side of deweller's household to the subject of ten apartment housings located in Gwang-ju, Jun-nam province. The study method was used the field study method and used in parallel with participant observation. As a result of the study, first, the problems of remodeling enforcement process are brought about standardized design, bad construction and the difficulty of solution in the defect occurrence. Second, By that request of the household is not reflected, the room except bedroom and the bathroom of inner room are low practical use degree. And wash space, garden space, assistant space of kitchen work were becoming hindrance factor of the residing environment because the use is irrational.

Purpose: This study is to derive the behavioral characteristics of the users appear in the outpatient department of psychiatry. Methods: By referencing John Zeisel's Tools for environment-behavior research, observation of user behavior and expert interviews as a method of the study has been carried out. Results: The results of this study are as follows. First, adjacent placement among children, youth and regular the outpatient department of psychiatry is necessary and easy access to internal medicine department and family medicine department is required in order to allow cooperated treatments. Secondly, depending on the characteristics of the outpatient department of psychiatry treatment, adjustment of space requirement or the change of kinds of necessary space is required. Third, considering the psychological and behavioral characteristics of mental illness and guardians, various search for the environment that can support this. Implications: This study is a basic research for space improvement and evaluation of the outpatient department of psychiatry, and need to be followed by further study using various perspectives and methods.

The study aims to find out the changing aspects of contemporary Korean libraries so called public in terms of their spatial configuration. In so doing, it analysed 14 recently built libraries by investigation of user's behavior. Interview and observation were conducted as a method of investigation. The method of analysis was based on statistics by mapping spatial data. As the result, it could be said that most users have a clear goal in Korea. In some libraries, the distinct characteristics of behavior show that users visit other functional rooms including functional rooms for the purpose. It could be said that the configuration of space in recently public libraries become more public as a place. In view of domestic affairs, in terms of users need, the reading room for personal study have features of the most private room and a static activity. so that the reading room separate from the other functional rooms in floor, but it adjoin other functional rooms in the horizontal configuration. so its location make offset a role of functional rooms can be interactive with each other, except reading room.

교수학습 사이트는 교과 교육 지원이라는 특성상 그 서비스 개선에 있어서 사용자 중심적 디자인이 특히 요구된다. 기존 웹사이트 개선 연구는 단순히 웹사이트와 사용자 간의 인터랙션에서 발생하는 문제점에 초점을 맞추어 왔는데 사용자의 근본적인 니즈를 발견하고 만족시키기 위해서는 웹사이트 사용 정황의 이해라는 보다 확대된 개념에서의 접근이 필요하다. 따라서 본 연구에서는 웹사이트의 문제점 발견 및 사용자의 근본적 니즈 파악을 위하여 오프라인과 온라인 환경에 걸친 사용자 경험 관찰 프로세스를 기획하고 교수학습 사이트 서비스 개선을 위해 이를 적용하였다. 사이트 비지팅(Site Visiting), 비디오 에쓰노그라피(Video Ethnography), 사용자 다이어리 및 셀프카메라(User diary and Self camera), 그리고 인터뷰 기법이 현장 조사에서 이용되었으며 원격 사용성 평가 소프트웨어를 활용한 사용성 평가 및 카드소팅 테스트가 온라인 환경에서 진행되었다. 관찰 후 분석을 통해 교수학습 사이트의 새로운 컨텐츠 및 서비스 방향을 도출할 수 있었으며 웹사이트 사용자 경험 관찰 방법론 정립에의 가능성을 제시하였다.
