Effects of Public Health Service Impartiality on Subjective Health Happiness: Mediated Effect of Public Health Service Quality / 보건행정학회지

BACKGROUND: The purpose of this study is to analyze the effect of impartiality in providing public health services on subjective health happiness and the mediated effects of public health service quality. Based on this, this study intends to present policy implications to improve public health services. METHODS: The research method is multiple linear regression analysis. The analysis of the mediating effects is performed by Baron & Kenny's test, Sobel-Goodman's test, and Bootstrap. RESULTS: The impartiality of public health services and the quality of public health services are shown to have a statistically significant effect on subjective health happiness. Quality of public health service appears to be mediating the relationship between impartiality in providing public health care and subjective health happiness. CONCLUSION: To promote people's subjective health happiness, it is necessary to secure impartiality in providing public health services in the first place and improve the quality of public health services.

Development of Optical Molecular Imaging System for the Acquisition of Bioluminescence Signals from Small Animals / 핵의학분자영상

PURPOSE: Optical imaging is providing great advance and improvement in genetic and molecular imaging of animals and humans. Optical imaging system consists of optical imaging devices, which carry out major function for monitoring, tracing, and imaging in most of molecular in-vivo researches. In bio-luminescent imaging, small animals containing luciferase gene locally irradiate light, and emitted photons transmitted through skin of the small animals are imaged by using a high sensitive charged coupled device (CCD) camera. In this paper, we introduced optical imaging system for the image acquisition of bio-luminescent signals emitted from small animals. MATERIALS AND METHODS: In the system, Nikon lens and four LED light sources were mounted at the inside of a dark box. A cooled CCD camera equipped with a control module was used. RESULTS: We tested the performance of the optical imaging system using effendorf tube and light emitting bacteria which injected intravenously into CT26 tumor bearing nude mouse. The performance of implemented optical imaging system for bio-luminescence imaging was demonstrated and the feasibility of the system in small animal imaging application was proved. CONCLUSION: We anticipate this system could be a useful tool for the molecular imaging of small animals adaptable for various experimental conditions in future.
