This study investigates the effect of types of usual source of care on medication adherence among the elderly. Using the Korea Health Panel Survey in 2017, this study includes 3,623 elderly people 65 years of age or older taking prescription drugs for treatment of chronic diseases. The type of usual source of care was considered in three aspects: whether having a usual source of care or not, whether having a regular site only or having a regular site and doctor, size of the regular site. The types of usual source of care are heavily associated with medication adherence. Compared to those who have no usual source of care, those who have a regular site only are 1.4 times, and have both regular site and doctor are 1.8 times more likely to comply with the medication guidelines, respectively. The finding shows usual source of care has a positive effect in improving medication adherence of the elderly. The results can provide an evidence for policies for effective management of chronic diseases and efficient use of medical resources.

Purposes: Diabetes is a metabolic disorder that requires continuous care in order to prevent complications, as it can impose a critical burden on families and society due to various complications, including terminal renal failure, non-traumatic lower extremity amputation, and adult blindness. The usual sources of care are "specified private clinics, public health centers, or other facilities to visit when ill or when health-related advice is needed". These usual sources of care offer preventative services, have a high overall satisfaction rate in terms of public health care, and decrease the inpatient rates and medical costs of medical aid recipients. This study analyzed the current status of diabetic patients over 20 years of age based on their possession of a usual source of care, and the effects of this possession on the frequency of their medical service usage and its costs. Methodology: Based on data from the 7th Korea Health Panel, a Tobit analysis was used to analyze the different factors that can affect the frequency of medical service usage and its costs for diabetic patients with and without a usual source of care. Findings: The medical costs of diabetic patients with a usual source of care decreased in terms of inpatient, and the outpatient visits and inpatient costs of the group with a usual source of care in the form of a mainly-visiting doctor decreased more than those of the group with a mainly-visiting medical institution only. Practical Implications: Having a usual source of care can increase the treatment continuity, leading to reduced inpatient, and having a mainly-visiting doctor as the usual source of care further increases the treatment continuity. Based on these results, a new policy is needed to increase and strengthen diabetic patients? possession of a usual source of care.

Purpose: The purpose of the study was to investigate and compare the usual source of healthcare and frequent visits to emergency departments. Methods: The study subjects were 7,252 individuals with chronic diseases who filled out the questionnaire of the 2013 Korea Health Panel Survey. Data were analyzed using chi-square test and logistic regression. Results: Compared to having a public health center or clinic as a usual source of healthcare, it is 1.341 times more likely for a chronic disease patient to visit an emergency department if the hospital is her/his usual source of healthcare, while it is 1.656 times more likely for the patient to visit a general/tertiary hospital. Conclusion: It is important to investigate visits at the emergency department requiring primary care for diseases.

Objectives: This study was conducted to analyze the dental care utilization patterns and related factors of the rural residents. Methods: The data collected by interview and self-administered questionnaire survey of 524 peoples of Seongju county in Gyeongsanbuk-do. The summarized results are as follows. Results: The rate of persons who experienced the oral disease was 52.5% during 1 year and it was at most in the age group of 40-49. The rate of persons who had experienced the oral disease were investigated according to general characteristics, perception of oral health, being of regular treatment facility. Therefore the rate of persons who had experienced the oral disease was significantly higher the younger peoples, worse oral health status and being of the regular treatment source than the other groups. During 1 year period, 64.0% of the cases had treated the perceived oral disease, 36.0% did no action at all during last year. Among respondents, 49.4% had treated their oral disease at dental clinics, 8.0% had treated at community health center or subcenter and remains did not treated at all. The results of logistic regression analysis suggested that statistically significant factors in dental health care utilization were educational level, degree of pain, oral health status and regular treatment facility. Therefore the dental health care utilization rate was higher at groups with the high educational level, serious pain, better oral health status and being of the regular treatment source than other groups. 45.5% of the rural residents did not treat their oral disease immediately due to the no identified need, limitation of time(19.2%), economic limitation(19.2%), and geographical limitation(9.0%). Conclusions: In consideration of above findings, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically.

2020년까지 전 세계 수송에너지의 수요가 현재의 2배까지 증가할 것으로 예상되면서 석유 자원의 안정적 공급이 어려워지기 이전에 이를 대체할 수 있는 에너지원 개발이 시급하다. 이러한 노력의 일환으로 최근 들어 대두되고 있는 가스화용융 기술은 석탄 폐기물 등으로부터 합성가스를 생산하는 고청정 고효율 기술이다. 여기에서 생산되는 합성가스는 천연가스를 대체하여 전기 및 화학원료를 생산하기 위한 원료로 이용 가능하다. 폐기물로부터 가스화용융기술을 통하여 생산되는 합성가스로부터 DME(dimethyl ether)를 생산할 수 있다. 가스화용융기술로부터 생산되는 합성가스는 자체의 일산화탄소와 수소의 조성비가 DME를 합성하는데 적당하다고 알려져 있다. DME는 에너지원의 다원화와 대기오염 물질의 저감, 지구온난화 대응 등과 아울러 제 4세대 수송 연료로 부각되고 있다. DME를 합성하는 방법은 합성가스로부터 메탄올의 합성 단계를 거친 후 DME를 합성하는 간접법과 단일단계의 반응에서 합성가스로부터 직접적으로 DME를 합성하는 직접법이 있다. 현재는 화학 평형적 측면 경제적 측면에서 이점을 가지고 있는 직접법에 관한 연구가 활발히 이루어지고 있다. DME 직접합성법에서는 메탄올 합성 촉매와 메탄올 탈수촉매의 물리적 혼합에 의한 혼성촉매가 주로 이용되고 있는 것으로 알려져 있다 본 연구에서는 일산화탄소와 수소로 이루어진 합성 가스로부터 직접 DME를 생산할 수 있는 직접 합성 공정에 적용 가능한 고효율 촉매 기술을 개발하기 위해 상용촉매의 스크린 테스트를 수행하였다. 상용촉매로는 sud-chemi사에서 메탄을 합성 촉매와 탈수촉매를 각각 구입하였으며, 이들 촉매를 원하는 조성비로 물리적으로 혼합한 다음 반응온도 ($250-290^{\circ}C$) 압력 (30-50 atm), $H_2$/CO 몰비 (0.5-2.0) 등의 다양한 반응조건 하에서 스크린 테스트를 수행하였다.대장조영영상을 얻을 수 있어 대장암의 위치에 관한 정보를 삼차원적으로 제공하므로 대장암의 성상을 정확히 알 수 있는데 도움을 주었다.요인은 없는 것으로 사료된다. 이 중 2예의 CT에서 선상 혹은망상형의 음영을 보였다. 결론: 유방암 환자의 방사선 치료 후 CT 소견은 방사선 치료의 방법에 따라 폐첨부 혹은 폐의전면 흉막하 부위에 선상 혹은 망상형의 음영으로서 방사선 폐렴 혹은 섬유화 소견이다. CT는 단순 흉부 촬영보다 이상 소견의 발견이 쉽다.이러한 소견은 후에 합병될 수 있는 다른 폐질환의 감별 진단에 도움이 될 것으로 보인다.moembolization via the radial artery approach were involved in this study.

Purpose : Many studies showed that having a usual source of care improved the efficient access of healthcare service. However in Korea there have been few studies on the usual source of care. So this study aims to find whether having a usual source of care affect the medical utilization and expense. Methodology/Approach : We used the Korean Health Panel data in 2012, 2013 to examine the change of utilization and expenses in ambulatory care affected by having a usual source of care. We selected 1,215 hypertension patients without usual source of care in 2012 and performed linear regression analysis to identify the difference between treatment group(with usual source of care in 2013) and control group(without usual source of care in 2013). Then we performed analysis again separated by the age group. Findings : Among study population, 711(58.5%) reported that they have a usual source of care in 2013. Treatment group reported 1.85 less increase in outpatient visits and 69,234 won less increase in expense than control group with weak significance(visit ${\beta}$ -1.85 p-value 0.0807, expense ${\beta}$ -69,234 p-value 0.0541). People under the age of 65 showed significant change in outpatient visits for tertiary hospital (visit ${\beta}$ -0.78 p-value 0.0154, expense ${\beta}$ -91,462 p-value 0.0168). The analysis which focused outpatient for mild disease showed similar trend. Practical Implications : This study supports the positive effect of having usual source of care which decrease inefficient outpatient utilization. Promoting physician-patient relationships is important for efficiency of healthcare service.

Background: This study examined the effect of having a usual source of care on the degree of patient-centered communication among persons with disability. The role of the usual source of care has been emphasized to improve patient experience, especially for patients with complex health conditions. Methods: This study used the 2017-2018 Korean Health Panel data, and the final study observations were 22,475 (20,806 people without disability and 1,669 people with disability). We applied generalized estimating equation model to show the effect of having a usual source of care on patient-centered communication, and subgroup analysis considering the types and severity of disabilities. Results: Persons who have disabilities, compared with ones without it, significantly had more usual sources of care (32.4% vs. 24.6%). By type of disability, persons with mental (51.4%), internal organ (43.8%), visual (37%), and physical disabilities (31.6%) had more usual sources of care than hearing/speech (26.6%), and developmental disabilities (18.6%). The average score of patient-centered communication was higher among who had a usual sources of care (3.2 vs. 2.7), and the regression analysis showed that having a usual sources of care was positively associated with higher patient-centered communication score (𝛽=0.476, p<0.05). However, the positive effects of usual sources of care was not observed among persons with severe hearing/speech, developmental, and mental disabilities. Conclusion: This study showed that role of patient-centered communication was limited in persons with severe hearing/speech disabilities, developmental, and mental disabilities. The education programs and supports are needed to improve communication skills between medical staff and persons with specific types of disabilities.

Background: Population aging is a serious problem in Korea. And we have experienced a rapid increase in the health expenditures of the elderly. The purpose of this paper is to analyze the effect of having a usual source of care (USC) for the elderly. Methods: This study used the Korea Health Panel Survey data of 2012, 2013, 2016, 2017, and 2018. The sample was the person who answered the USC questions among the elderly. The panel logit model was used to analyze the determinants of having USC and the panel simultaneous equation model was used to analyze the effect of having USC among the elderly on the medical expenses, medical utilization, and subjective health status. Results: The estimation result shows that age, income, marriage, and so forth turn out to be the factors of having USC. Having the clinic level USC is estimated to reduce the health care utilization and the health expenditure and to improve the subjective health status. Conclusion: It is expected that the result of our analysis will provide evidence for encouraging having USC.
