We introduce a rotating-gantry-based x-ray micro-tomography system to be used for small animal imaging studies. It has the zoom-in imaging capability for high resolution imaging of a local region inside the animal subject without any contrast anomalies arising from truncation of the projection data. With the sliding mechanism mounted on the rotating gantry holding the x-ray source and the x-ray detector, we can control the magnification ratio of the x-ray projection data. By combining the projection data from the large field of view (FOV) scan of the whole animal subject and the projection data from the small FOV scan of the region of interest, we can obtain artifact-free zoomed-in images of the region of interest. For the acquisition of x-ray projection data, we use a $1248{\times}1248$ flat-panel x-ray detector with the pixel pitch of 100 mm. It has been experimentally found that the developed system has the spatial resolution of up to 121p/mm when the highest magnification ratio of 5:1 is applied to the zoom-in imaging. We present some in vivo rat femur images to demonstrate utility of the developed system for small animal imaging.

In order to strengthen assurance of National Health Insurance, co-payment should be reduced. This can happen with collaborative efforts of patients, medical institutes, and government altogether at the same time. This research applied Dutton(1986)'s medical service research model with high R-square, and analyzed 2008 Korea Health Panel Data (Beta Version 1), that was examined by Korea Institute for Health and Social Affairs and National Health Insurance, in order to figure out influential variables on co-payment. In result of Multiple Linear Regression Analysis, R-square was 46.7%, the older the age, the patients who had surgery, the longer days of hospital treatment are, the higher gross income of a household is, the more hospitalized in upper grade general hospitals, and the more upper grade rooms and selecting a doctor are used. The results have statistical significance. When conducting research applying medical service research model, there is a need to apply Dutton(1986)'s medical service research model with high R-square. In order to strengthen assurance of National Health Insurance, first conditions should be that patients are hospitalized in upper grade general hospital, and at the same time, are patients who had surgery with long stay of hospitalization. In addition, if proven that patients used upper grade rooms and selecting a doctor due to lack of regular treatment and rooms, for certain number of days of such hospitalization, it is suggested to be provided with health care insurance in upper grade rooms and selecting a doctor in calculating co-payment limit.

Since the inauguration of the medical insurance system in 1977, the increasing medical expenses which can be menace to tile finance of the medical insurance system, have become major concern in the medical insurance field In Korea. This study focuses on the determinants of the medical expenses in the health insurance in Korea and analyzes the impact of these factors on the increase in the medical expenses. The empirical work is done using the pooled cross-section and time-series data of the medical insurance for the self-employeds and the industrial workers from the year 1995 to 1997. The result of this study shows that the main determinants of the medical expenses in the health insurance are the ratio of the population of the aged to the total population, the frequency of the utilization, number of doctors per capita and the regime changes. Although the increasing trend in the medical expenses seems to be unavoidable, we probably need to add some efficiency to the medical expenses by suppressing the supply and the utilization of the unnecessary medical services. The fee-for-service reimbursement system of today can't suppress the supply of the unnecessary medical services effectively. So we need to convert the present fee-for-service system into DRG's which is known to reduce the medical costs. The increase in the medical expenses comes from a lot of factors. Therefore, we should develop more systematic and comprehensive measures to control the soaring medical expenses in consideration of the various factors such as demand, supply, and the organizational side of the medical system.

Objectives : This study aimed to analyze the structure and the trend of utilization and expenditure for Korean Medicine (KM) in Korea. Methods : Data were drawn from the 2008-2013 annual Korea Health Panel (Version 1.2.2), a national representative sample. We combined the data of household members with the data of outpatient KM service use. The volume of KM use was estimated based on the frequency of use and co-payment. Results : The KM utilization rate slightly increased in recent years, and it is presumed to be resulted from the increase of elderly population. Most KM outpatient visits were being concentrated in treating musculoskeletal diseases, and the procedures used frequently were acupuncture, moxibustion, cupping, and physical therapy. The imbalance of KM use between lower income group and higher income group was deepening. Conclusions : To expand restricted disease areas KM covered, the more herbal prescriptions should be insured and the insured form of herbal medicines need to be diversified.

Purposes: This study aims to investigate the changes in the length of stay and medical expenses by the impact of the admission decided by patients or their family. Methodology: The analysis was conducted using data from elder patients aged 65 or older who have used admission services more than once from year 6(2012) to year 12(2017) of the Korean Medical Panel Data(KOWEPS). The statistical analysis was performed through the Chi-square test, mean difference analysis, and generalized estimation equation analysis. Findings: Compared to the patients who used admission services decided by doctors, those who used admission services decided by patients or their family had a longer length of stay and a lower daily medical expense. Practical Implications: Inappropriate admission decided by patients or their family can increase the risk of hospital-acquired infections, impairing the health of elderly patients, and has a negative impact on the efficiency of health resources. Therefore, it is necessary to prevent and properly manage inappropriate admission decided by patients or their family

Introduction: Previous studies on occupational health focussed predominately on the occurrence of occupational diseases. Relatively few studies have measured how employment is associated with the use of healthcare services. This study investigates the association between employment and the extent and range of healthcare use, such as medical expenditures, of women in South Korea. Methods: We analyze data of the Korean Health Panel, an ongoing longitudinal national representative survey, from 2008 to 2017, to identify the status of economic activity of women by year and age group. We estimate the association between female employment status and medical expenditures by using random effect panel Tobit models. Furthermore, we investigate the association between employment status and the range of healthcare services in biomedicine and traditional Korean medicine (KM) by conducting conditional fixed-effects logistic regression analyses. Results: For women aged between 25 and 65 in 2017, the majority of them were employed or self-employed. (The proportion of employment of self-employment equals 64.80%). In addition, working women spent 11.6% less on healthcare than nonworking women, and self-employment lowered the healthcare expenditure by 13.1%. Neither work nor the type of work is related to the types and range of healthcare service use. Being employed or self-employed is negatively associated with women's expenditure on healthcare. Conclusions: The findings show that employment is associated with less spending on healthcare. They imply that employment has a positive impact on women's health.

Background: The purpose of this study was to examine the impact of the regional characteristics on the accessibility of emergency care and the impact of emergency medical accessibility on the patients' prognosis and the emergency medical expenditure. Methods: This study used the 13th beta version 1.6 annual data of Korea Health Panel and the statistics from the Korean Statistical Information Service. The sample included 8,119 patients who visited the emergency centers between year 2013 and 2017. The arrival time, which indicated medical access, was used as dependent variable for multi-level analysis. For ordinal logistic regression and multiple regression, the arrival time was used as independent variable while patients' prognosis and emergency medical expenditure were used as dependent variables. Results: The results for the multi-level analysis in both the individual and regional variables showed that as the number of emergency medical institutions per 100 km² area increased, the time required to reach emergency centers significantly decreased. Ordinal logistic regression and multiple regression results showed that as the arrival time increased, the patients' prognosis significantly worsened and the emergency medical expenses significantly increased. Conclusion: In conclusion, the access to emergency care was affected by regional characteristics and affected patient outcomes and emergency medical expenditure.
