In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

Objectives: The purpose of this study was to provide hospital management diagnosis status and basic data required for the future development of hospital management diagnosis program. Methods: We conducted a questionnaire survey on administrative staff of manager level or over of medical institutions in B metropolitan city. Results: As a result of analyzing the relative influence of the needs by hospital management diagnosis indicator, the effect of financial analysis indicator, patient treatment record indicator and medical revenues indicator were high in the medical institutions with number of beds of 100 beds or over and general hospital level or over both on a hospital level and on an individual level. Conclusions: Since the existing laws or systems are centered on large major hospitals, the management environment is very unfavorable for small and medium hospitals as can be seen from the results of this study. Therefore, the government should improve the transparency and rationality of the hospital management environment in Korea through regulation and system reforms that can be applied to all medical institutions.

Purpose: The purpose of this study was to explore the influence of care stress for older patients, self-perceptions of aging, and anxiety about aging on preparation for retirement in clinical nurses. Methods: This was a cross-sectional descriptive study in which participants were 222 nurses who had at least six months of work experience and were involved in caring for older patients in the last six months at the work site. Data were collected from August to September, 2020 using an online survey questionnaire. Data were analyzed using the IBM SPSS/WIN 25.0 program. Results: The mean level of preparation for retirement in the participants was moderate (3.21 out of 5 points). Among the sub-domains of preparation for retirement, financial preparation had the lowest score. Self-perceptions of aging and aging anxiety were significant predictors for retirement preparation in nurses, accounting for 16% of the variable's total variance. Conclusion: A greater level of preparation for retirement was associated with a positive perception of aging and a decreased level of aging anxiety in the clinical nurses. Further research should focus on exploration of specific determinants of financial preparation for retirement and development of intervention strategies for improving preparation for retirement in the nursing workforce.

This study examines health and life satisfaction of the married female production workers(Mfpw). The data of 370 Mfpw in manufacturing sector in Taegu are collected by using questionares in August, 1995. Health scale measured by Todai Health Index is composed physical health and mental health. There are three satifsfaction areas-individual life satisfaction, family life satisfaction, and job satisfaction-in the overall life satisfaction scale. The findings of this study are as follows: 1) Mfpw’s total health conditions are poor. Especially physical health is worse than mental health. Physical health is influenced by age and purpose of attaining job, while mental health is influenced by purpose of attaining job. Mfpw who get the job for family financial needs have poor physical and mental health. 2) The overall life satisfaction level of Mfpw is lower than middle point : their family life satisfaction level is the heigest and their individual life satisfaction level is the lowest. Family income, purpose of attaining job and work place environment have effect on the level of overall life satisfaction. Mfpw who have the higher family income, get the job by non-economic motivations and work in good work place environment show the higher life satisfaction level.

Background: This study purposed to analyze the relationship between regional obesity rates and regional variables. Methods: Data was collected from the Korean Statistical Information Service (KOSIS) and Community Health Survey in 2012. The units of analysis were administrative districts such as city, county, and district. The dependent variable was the age-sex adjusted regional obesity rates. The independent variables were selected to represent four aspects of regions: health behaviour factor, psychological factor, socio-economic factor, and physical environment factor. Along with the traditional ordinary least square (OLS) regression analysis model, this study applied geographically weighted regression (GWR) analysis to calculate the regression coefficients for each region. Results: The OLS results showed that there were significant differences in regional obesity rates in high-risk drinking, walking, depression, and financial independence. The GWR results showed that the size of regression coefficients in independent variables was differed by regions. Conclusion: Our results can help in providing useful information for health policy makers. Regional characteristics should be considered when allocating health resources and developing health-related programs.

Purpose: The purpose of this study is to develop the curriculum model for occupational health nurse specialist in Korea. Method: Internet searching was conducted to analyze the type of master program for occupational health nurses in the U. S. To identify the importance of occupational health nurse specialist (OHNS)'s role, self-administrative questionnaire survey was done to335 occupational health nurses through postal mail and continuing education in 2003. SPSSWIN 10.0 was used for data analysis. Results: In the U. S., two main types of nurse practitioner program and nurse manager program are separately operated for occupational health nurses as master level. Under the governmental support, geographical and financial barrier can be decreased through the distance learning and the appointment of regional ERC. Most occupational health nurses recognized importantly the role of OHNS as direct care provider, educator, consultant, and manager. Conclusion: It is recommended that the job standard for OHNS needs to be developed, and regulation has to be changed for the diverse curriculum based on the need of occupational health nurses, and governmental support must be strengthened for occupational health nurses to apply more easily to the program.

This study was conducted to evaluate the subjective ideas about the determinants of quality in ambulatory care unit among outpatients and medical staff of a university hospital, and to compare the differences of the ideas, between patients themselves and hospital staff. A self-administered questionnaire survey was conducted covering 799 outpatients and 190 hospital staff in March, 1998. The questionnaire included general characteristics and 26 determinants of ambulatory care quality. The following are summaries of the findings: 1. Both of outpatients and hospital staff perceived, "Physician's knowledge" as the most important determinant of medical care quality. 2. In respect of 7 determinants related to physician's knowledge and skill, both outpatients and hospital staff perceived "physician's knowledge and skill" as important determinants. The scores of determinants such as, "Not doing unnecessary examinations", and "Assignment of adequate number of patients and duty schedule for the physician" were significantly different between outpatients and hospital staff. 3. In respect of 4 determinants related to doctor-patient relationship, both outpatients and hospital staff perceived "attention to patient's complaints" as the most important determinant. The scores related to the determinants such as "kindness of physician" and "explanation of treatment outcome" were significantly different between outpatients and hospital staff. 4. Among the amenities related determinants, "Modern facilities and equipments" were perceived as the most important determinant in both group. 5. In respect of 8 determinants related to non-financial accommodation, outpatients perceived, "Waiting hours for treatment" as the most important determinant, and hospital staff perceived, "Kindness of hospital staff". 6. In respect of 4 determinants related to financial accommodation, outpatients perceived, "Fare account of medical cost" as the most important determinant, and hospital staff perceived, "Increasing reimbursements". Further comprehensive research should be made on the evaluation of perceptions of medical care quality, both of outpatient and inpatient care, among patients and hospital staff. So good quality in medical care will be achieved based on clients' needs.

Purpose: This study was aimed to examine the financial effect of 2-tiered copayment system on annual expenditure of pharmacy benefit in the National Health Insurance (NHI) of Korea, focusing on oral antidiabetic medications. Methods: 284 oral antidiabetic products with 14 different active single ingredients listed in the National Formulary of NHI (August 2009) were assigned to tier 1 or tier 2 according to the selected criteria. 10 different combinations of coinsurance rates were selected to estimate the changes in drug expenditure cost of NHI. Results: The annual drug cost was estimated based on the drug price per unit listed in the National Formulary and the used amount of products in 2009 from the IMS Health data of Korea. In the combinations of coinsurance rate of 20% for tier 1 and 40% for tier 2, the total annual drug cost was estimated to be reduced by 1.3% in the case of no change of generic and original drug consumptions, and to be reduced by 4.3% in the case of 10% increased generic drug consumptions. Conclusion: The tiered copayment system with optimal coinsurance rates appears to be a potential strategy to reduce the financial burden of NHI in Korea by promoting the use of generic products.

The purpose of this study is to find the determinant variables to make profitability in regional public hospitals. The data come from financial statements and annual reports of 34 regional public hospitals for five years (from year 2003 to year 2007). The T or F-test and hierarchical multiple regression analysis are used. The dependant variables are the profitability indicators, ordinary income to total asset and operating margin to gross revenue, and the independent variables are general characteristics, diagnosis and treatment patterns, financial and public benefits. The findings of this study are summarized as follows. First, Variables affecting the profitability indexes revealed from DEA results is the bed occupancy rate, number of hospitalized patients to outpatients, ratio of first medical examination for outpatients, number of daily patients per medical specialist, labor cost per patient and managerial expenses per patient. Second, the ordinary income to total asset representing the asset usage performance is affected by the average hospitalized days, bed occupancy rate, labor cost per patient and ratio of patients with medical insurance coverage. Third, the operating martin to gross revenue obtained from the actual operations of hospitals has its significance with the bed occupancy rate, number of hospitalized patients to outpatients, managerial expenses per patient and public benefit indicator. This study has some restriction not to use pannel data analysis, although it used data for five years. Accordingly, various additional studies should be done to supplement such problems.
