초창기의 어려웠던 환경을 극복하면서 이제 점차 내실을 기하며 발전하는 우리나라 의료보험제도는 그간 의료시혜의 광대란 측면에서 복지제도의 굵직한 자취를 남겨놓은데 그 의의를 찾을 수 있겠다. 그러나 보다 많은 수혜자, 견실한 보험재정의 유지, 의료기관의 발전이란 측면에서 모두 진립시켜 나가기에는 계속적인 제도상의 연구가 뒷받침되어야 하리라 본다. 본 고는 우리나라 의료보험 제도중에서 특히 의료비지불제도에 관심을 갖고 선진외국의 의료비제도를 고찰하고 비교하므로써 우리나라 진료비 심사 및 지불제도에 관한 이해를 도모하고자 게재하는바이다

겨울철만 되면 전국 관공서나 방송에서 화재위험 및 예방에 대해서 강조한다. 그만큼 겨울에는 난방을 위해서 가정, 사무실 공장 등 난방용품을 많이 사용해서 화재위험이 높아지기 때문이다. 특히 비용이 적고 사용이 간편하다는 장점 때문에 전기히터, 전기 장판과 같은 전기를 이용하는 난방용품의 사용이 급증한다. 이렇게 겨울철에 많이 사용하고 있는 전기를 안전하게 사용하는 방법은 무엇일까? 또한, 콘센트에는 전기기기 몇 개나 연결하여 사용할 수 있는 걸까? 이번 호에는 전기안전 및 콘센튿 사용에 관한 화재안전에 대하여 일아보고자 한다.

This paper is concerned with the statistical analysis and development of stochastic models for the demand for life insurance policy loans. For these, firstly the characteristics of the regression trend, periodicity and dependence of the monthly demand for life insurance policy loans are investigated by a statistical analysis of the monthly demand data for the years 1999 through 2008. Secondly, the causal relationships between the demand for life insurance policy loans and the economic variables including unemployment rate and inflation rate for the period are investigated. The results show that inflation rate is main factor influencing policy loan demands. The overall evidence, however, failed to establish unidirectional causality relationships between the demand series and the other variables under study. Finally, based on these, univariate time series model and transfer function model where the demand series is related to one input series are derived, respectively, for the prediction of the demand for life insurance policy loans. A statistical procedure for using the model to predict the demand for life insurance policy loans is also proposed.

The competition among insurance companies has become increasingly intense driven by the recent changes in financial environment. In this study, we (i) categorize the quality of life insurance services into the core service, relational services, and additional services, (ii) assess the impact of each service on repurchase intension, and (iii) investigate if customer satisfaction has a mediating effect. The research subjects are 215 life insurance customers who were selected from an online survey respondent population. Based on the analysis we performed by utilizing the SPSS 18.0, we concluded that (i) maintaining service of the core services, internal relationship of service personnel and insurance salesmen of the relational service and additional services have a positive impact on repurchase intention and (ii) In the relationships between repurchase intentions, the customer satisfaction is fully mediated by maintaining service and insurance salesman and partially mediated by additional service. The results of this study can be meaningful for both industry and academia, because these results can be utilized as useful evidence in understanding selection behavior of life insurance customers and deriving various strategies in business environment.

Japanese state has continuously tried to adapt itself to the social demands coming from rapidly greying population. Japanese government introduced the new social insurance system of elderly care, i.e. Long term Care Insurance with epoch-making changes in the Japanese welfare system. The most important aspects of the new system can be summarised as follows: 1) social insurance system of obligatory entry with paying premiums and co-payment 2) emphasis on the customer choice, competition, flexibility, free-market, relaxation of the regulation. This characteristics brought unexpected results of the emergence of ethnicity-centred contents of welfare services. As a selling point in freemarket and as a countermeasures against expected ethnic disadvantages, the Korean ethnic organisations brought the ethnic elements resulting in the diversified Japanese welfare services.

The purpose of this study was to review literature about private health insurance (PHI) schemes for Korean older adults published in Korea and abroad from 2015 to 2019, and to present the implications of the study and provide an overview of PHI utilization by Korean older adults. Nineteen quantitative academic research papers were selected and analyzed with respect to presentation time, research purpose, data source, and study design. Old age, low income, low education, and chronic disease were found to hinder enrollment in PHI schemes. Although the relationship between PHI and medical usage was not consistent, it was positively related to health outcomes such as subjective health status and health-related quality of life. Therefore, for PHI to fulfill the role of providing supplementary medical care for older adults with high medical demands, a national improvement policy should be developed to address the barriers that prevent older adults adopting PHI schemes, and empirical studies related to medical usages by and the health outcomes of older adults should be conducted in order to generate a basis for the use of PHI.

Predicting insurance claims is a key task for insurance companies to manage risks and maintain financial stability. Accurate insurance claim predictions enable insurers to set appropriate premiums, reduce unexpected losses, and improve the quality of customer service. This study aims to enhance the performance of insurance claim prediction models by applying ensemble learning techniques. The predictive performance of models such as Random Forest, Gradient Boosting Machine (GBM), XGBoost, Stacking, and the proposed Dynamic Weighted Ensemble (DWE) model were compared and analyzed. Model performance was evaluated using Mean Absolute Error (MAE), Mean Squared Error (MSE), and the Coefficient of Determination (R²). Experimental results showed that the DWE model outperformed others in terms of evaluation metrics, achieving optimal predictive performance by combining the prediction results of Random Forest, XGBoost, LR, and LightGBM. This study demonstrates that ensemble learning techniques are effective in improving the accuracy of insurance claim predictions and suggests the potential utilization of AI-based predictive models in the insurance industry.

In the financial industry, the decision tree algorithm has been widely used for classification analysis. In this case one of the major difficulties is that there are so many explanatory variables to be considered for modeling. So we do need to find effective method for reducing the number of explanatory variables under condition that the modeling results are not affected seriously. In this research, we try to compare the various variable reducing methods and to find the best method based on the modeling accuracy for the tree algorithm. We applied the methods on the pension insurance of a insurance company for getting empirical results. As a result, we found that selecting variables by using the sensitivity analysis of neural network method is the most effective method for reducing the number of variables while keeping the accuracy.

The aim of this study is to investigate the awareness and perception of pediatric dentists regarding dental health insurance (DHI) system in Korea. Online surveys were sent to the members of the Korean Academy of Pediatric Dentistry (KAPD), and the responses were collected. The survey, consisting of 41 questions, was subdivided into 'general background of the respondents', 'the awareness on national health insurance (NHI) and DHI', 'the awareness on DHI pertaining to pediatric dentistry', 'issues that need improvement on DHI pertaining to pediatric dentistry', 'DHI claims', and 'the roles of KAPD in DHI'. In total, 302 responded, with a response rate of 28.9%. Excluding 2 questionnaires with insufficient answers, a total of 300 survey results were analyzed. According to the analysis, pediatric dentists thought that the coverage of DHI was not as sufficient compared to that of NHI, but were expecting its scope to broaden in the future. The satisfaction rate was higher in pit and fissure sealant and composite resin filling than in caries-detecting quantitative light-induced fluorescence. Pediatric dentists considered permanent tooth composite resin filling (65.7%) needed an increase in insurance copayment, while topical fluoride application (74.7%) to require insurance coverage. DHI claims were generally handled by dental hygienists and/or nursing assistants. Approximately half of the respondents answered that they have had experiences on appealing for insurance denials. Lastly, pediatric dentists generally had a positive attitude towards providing information for the DHI. This study is expected to be used as a sound dataset for the DHI policy development concerning pediatric dentistry.
