Background: This study aimed to explore factors associated with the non-use of beneficiaries of long-term care insurance services for the elderly in Jeollanam-do Province by analyzing a dataset obtained from National Health Insurance Service. Methods: The study sample consists of 1,663 individuals who were evaluated as eligible for long-term care insurance services in Je-ollanam-do Province during the period of July 1, 2008 through June 30, 2009. As a dependent variable, the non-use of the service was defined as one when a beneficiary had used it once or more times during one year after he or she was evaluated as eligible and as zero otherwise. A proportion analysis was conducted to describe characteristics of study sample. Chi-square tests were used to compare general characteristics between beneficiaries who had used the services and those who had not used them. Multiple lo-gistic regressions were performed by three models including additional sets of explanatory variables such as socio-demographic characteristics, health conditions, and economic status. Results: Main results are summarized as follows. The proportion of beneficiaries who had not used the service was 14.5% of all ben-eficiaries. According to the results from the model using all explanatory variables, the factors associated with the non-use of the ser-vices were residence location, dwelling place, type of desired service, level of care needs, and instrumental activities of daily life limi-tations. Conclusion: In particular, regarding the type of desired service, the cash benefit showed a high likelihood of the non-use of the ser-vice; it had an odds ratio (OR) of 50.212 (95% confidence interval [CI], 24.00-105.04) compared with home service. In case of dwelling place, a hospital showed also a high likelihood of the non-use with an OR of 20.71 (95% CI, 10.12-42.44) compared with home.
깊이 기반 3차원 영상 렌더링에서 투명한 스플랫을 사용한 가시성 기법
서모영(Mo Young Suh),정우남(Woo Nam Chung),한탁돈(Tack Don Han) 한국정보과학회 2005 한국정보과학회 학술발표논문집 Vol.32 No.2
본 논문에서는 투명한 스플랫을 사용한 깊이 기반의 3차원 이미지(Depth image based 3D rendered image) 렌더링에서의 가시성 기법을 제시한다. 이는 기존의 두 개의 패스로 이루어지는 가시성 기법을 z-버퍼 알고리즘과 변화된 McMillan’ s 알고리즘을 사용하여 하나의 패스로 구성함으로써 성능을 향상시켰다. 또한 스플랫의 순서에 따라 올바르지 않은 기준설정으로 인해 발생하는 화질의 문제점을 McMillan’ s 알고리즘을 수정함으로써 해결하였다.
Hierarchical Processing Architecture with Dynamically Allocated Nodes for 3D Graphics Shader
하상원(Sang-Won Ha),정우남(Woo-Nam Chung),한탁돈(Tack-Don Han) 한국정보과학회 2008 한국정보과학회 학술발표논문집 Vol.35 No.2
Flexible programmability has become the key issue in polygon-based rasterization on 3D graphics hardware in endowing realism to the final image displayed. Yet, data parallelism must also be exploited in order to ensure performance at interactive rate. In this paper, a new hierarchical architecture based on both MIMD and SIMD, otherwise known as heterogeneous chip multiprocessing, is presented along with dynamically allocated nodes to provide load balancing in 3D graphics, physics simulation, and general-purpose programming.
