무엇이 사용자를 실감나게 하는가? 본 연구에서는 3D 디스플페이(3D Display)를 대하는 사용자의 관점이 지각된 사실성을 통해 사용자 실재감에 미치는 영향을 검증하고자 한다. 공간인지 개념을 3D 디스플레이(3D Display)를 대하는 사용자 관점에 도입하여, 사용자가 자기중심적(Egocentric), 환경중심적(Allocentric)인 관점을 가지고 디스플레이를 바라볼 때의 사용자 실재감에 대해 연구하고자 한다. 연구 방법으로는 1차 연구에서 정성 조사를 실시하였다. 유희/실용 서비스의 6개의 영역에서 사용자가 3D 디스플레이(3D Display)와 상호 작용하는 행태를 관찰 및 인터뷰 과정을 거쳐 Grounded Theory를 통해 이론적 모형을 구축하였다. 2차 연구에서 연구 모형을 설문을 통해 검증하였다. 결과적으로 1차 연구에서는 사용자 실재감에 영향을 미치는 3D 디스플레이(3D Display)의 시스템 요인 10개를 도출하였으며, 2차 연구를 통해 사용자 실재감에 대한 3D 디스플레이(3D Display) 모형을 구축 및 검증하였다. What make users feel real? In this study, we testify the impact of user's spatial perspective to achieve presence in 3D display. By introducing the concept of spatial cognition to the users' perspective toward 3D display, we suggest that the presence can be varied according to the self-centered (Egocentric) perspective and environment-centered (Allocentric) perspective. In Study 1, Qualitative research methods conducted. A theoretical model was constructed through Grounded Theory and by investigating in 6 hedonic and utilitarian services, observing interactions with 3D Display and users. In Study 2, the model was verified through the survey. As a result of Study 1, we revealed 10 system features of 3D Display which affects users' presence, and in Study 2, we constructed and testified a model for users' presence in 3D display.

Public health system and public health practice have changed over the past decades as the result of social and epidemiologic changes. New public health concept emphasizes leadership, strategical thinking, systematic planning and effective performance to identify and solve complex health problem In Korea, the role of Health Center has been expanded rapidly. However there is strong suspicion that Health Center can achieve their mission. This paper aims at understanding what is the needed functions of Health Center and which of its aspects needs improvement. The main results of this study are summarizes as follows. District Health Law does not address the core functions of Health Center. The staffs of Health Center have difficulties in prioritizing their services. The recent attempt to restructure Health Center and change delivery pattern of public health services ended with only limited success. To effectively confront threats to the public's health, the three major function of Health Center must be ${\circled}1$ modifying individual behavior and lifestyle, ${\circled}2$ improving social and economic conditions, and ${\circled}3$ reforming health policies. Better results do not come from setting new functions only; they come from understanding and improving the processes that will then leads to better outcome. We recommend that policy-makers focus economic evaluation of public health programs, building and spreading of the scientific evidence of programs, linkage of public health research and public health program. The criteria of delegation of public health service to private sector is urgently needed. Making community health information data available on a routine basis to providers, managers and researchers of public health services helps promote the efficiency of the overall operation of public health system.
