Purpose: Importance of patient satisfaction related to patient-centeredness has been emphasized, and it is known to have effect on various health outcomes including health resource utilization. However, the effect of patient satisfaction has been discussed mostly in terms of hospital marketing in Korea. This study aims to examine the effect of patient satisfaction in patient-physician communication on healthcare utilization in a nationally representative adult population of South Korea. Method: Patient satisfaction with physician communication is assessed using 4 items in the 2011 Korea Health Panel Survey. Generalized linear regression analysis is conducted using 9,325 adults' healthcare utilization in 2012. Findings: Adjusting for the socio-demographic, economic factors, individual health status, health behaviors and healthcare utilization in 2011, more satisfied individuals, more likely to utilize the outpatient service, especially in clinical setting. Practical Implications: The study findings suggests that in context of South Korea healthcare system such as insufficient medical consultation time and the absence of health delivery system, patient satisfaction as a subjective healthcare quality indicator would have effect on the individual's outpatient visit. This study contributes to stimulate patient satisfaction research and discussion in South Korea to further explore its relationship with potential and various health related outcomes. Further implications of the study are discussed.

In order to estimate the utilization pattern of a rural health subcenter, and to identify the recognition for it among the inhabitants in Kogsung district, a questionnaire survey was carried out for objects of 708 population. The results observed were as follows; 1. The annual utilization rate of a rural health subcenter for a basic health service unit was 27.5 per 100 persons, and annual mean visiting times was 1.43 times. 2. The most frequent disease by, annual health subcenter utilization illness was respiratory disease(26.5%), and the next was musculoskeletal disease(23.9%), gastrointestinal disease(15.9%) by order. 3. Favorite reasons for community health subcenter utilization were lower medical cost(23.4%), near distance from living place(20.7%) and lower disease severity(19.5%) by order. But disfavorite reasons for it were non effective treatment(26.2%), insufficient equipment(25.4%) and absence of specialist(17.4%) by order. 4. Insufficient items about community health subcenter utilization were restriction of treatment limit(47.1%), lower reliance(22.4%) and not punctral(21.8%) by order. 5. The results of logistic regression analysis suggested that statistically significant factors in health subcenter utilization were age, educational level and the nearest medical facility class. 6. There was no difference between recognition for a community health subcenter's work and actual utilizing service, and desirable works for it were disease preventing service, disease control of elderly and sanitation control by order. These results suggested that to increase the utilization of rural health subcenter and to promote the accessibility of rural residents to primary health care, there must be considered public relation about health subcenter, expansion of health equipment and recognition about access time.

Objective: The aim of this study was to clone the mRNA sequence of the Acyl-CoA dehydrogenase long chain (ACADL) gene of goats and explore the effect of ACADL on the differentiation of subcutaneous fat cells on this basis. Methods: We obtained the ACADL gene of goats by cloning and used quantitative real-time polymerase chain reaction (qPCR) to detect the ACADL expression patterns of different goat tissues and subcutaneous fat cells at different lipid induction stages. In addition, we transfect intramuscular and subcutaneous adipocytes separately by constructing overexpressed ACADL vectors and synthesizing Si-ACADL; finally, we observed the changes in oil red stained cell levels under the microscope, and qPCR detected changes in mRNA levels. Results: The results showed goat ACADL gene expressed in sebum fat. During adipocyte differentiation, ACADL gradually increased from 0 to 24 h of culture, and decreased. Overexpression of ACADL promoted differentiation of subcutaneous adipocytes in goat and inhibited their differentiation after interference. Conclusion: So, we infer ACADL may have an important role in positive regulating the differentiation process in goat subcutaneous adipocytes. This study will provide basic data for further study of the role of ACADL in goat subcutaneous adipocyte differentiation and lays the foundation for final elucidating of its molecular mechanisms in regulating subcutaneous fat deposition in goats.
