R은 강력한 분석과 가시화 기능을 제공함에 따라 빅데이터 시대에서의 기본 분석 플랫폼으로 각광받고 있음에도 불구하고 규모 확장성 미비에 따른 성능 제약이라는 단점을 가지고 있다. 이를 해결하기 위한 방법으로 RHadoop 패키지가 공개되어 있으며 이를 통해 R로 개발된 프로그램이 하둡을 통해 병렬 분산 처리가 가능한 특징이 있다. 본 논문에서는 공공데이터의 개방에 따라 인터넷을 통해 공개된 각종 보건의료 빅데이터의 분석에서 RHadoop 패키지의 활용이 얼마나 유효한 지를 검증하고자 하였다. 이를 위해 국민건강보험공단에서 제공한 2015년 진료내역정보를 이용하여 R과 RHadoop의 분석 성능을 비교 검증한 결과 RHadoop이 효과적으로 분석 성능을 개선시킬 수 있음을 입증하였다.

The Korean Long-Term Care Insurance (K-LTCI) provides financial support for long-term care service to people who need various types of assistance with daily activities. As the number of elderly people in Korea is expected to increase in the future, the demand for long-term care insurance would also increase over time. Projection of future expenditure on K-LTCI depends on the number of beneficiaries within the grading system of K-LTCI based on the test scores of applicants. This study investigated the suitability of mixture distributions to the model K-LTCI score distribution using recent empirical data on K-LTCI, provided by the National Health Insurance Service (NHIS). Based on the developed mixture models, the number of beneficiaries in each grade and its variability under the current grading system were estimated by simulation. It was observed that a mixture model is suitable for K-LTCI score distribution and may prove useful in devising a funding plan for K-LTCI benefit payment and investigating the effects of any possible revision in the K-LTCI grading system.

PURPOSE. This study aims to assess and predict lifespan of dental prostheses using newly developed Korean Association of Prosthodontics (KAP) criteria through a large-scale, multi-institutional survey. MATERIALS AND METHODS. Survey was conducted including 16 institutions. Cox proportional hazards model and principal component analysis (PCA) were used to find out relevant factors and predict life expectancy. RESULTS. 1,703 fixed and 815 removable prostheses data were collected and evaluated. Statistically significant factors in fixed prosthesis failure were plaque index and material type, with a median survival of 10 to 18 years and 14 to 20 years each. In removable prosthesis, factors were national health insurance coverage, antagonist type, and prosthesis type (complete or partial denture), with median survival of 10 to 13 years, 11 to 14 years, and 10 to 15 years each. For still-usable prostheses, PCA analysis predicted an additional 3 years in fixed and 4.8 years in removable prosthesis. CONCLUSION. Life expectancy of a prosthesis differed significantly by factors mostly controllable either by dentist or a patient. Overall life expectancy was shown to be longer than previous research.

Objective: Using the Korean Health Panel data (KHP) of 2008 and 2009, this paper analyzed the effect of antihypertension medication adherence on the changes in medical service utilization and medical expenditure in the next year. Method: Through a face-to-face interview survey, KHP has provided an extensive data on demographic characteristics, medical utilizations behavior, medical expenditure and health behaviors of the targeted households and their members since 2008. KHP is recognized as highly accurate regarding medical expenditure in that it makes the target households to record 'Health diary' whenever they use healthcare service, which could minimize their cognitive bias or memory distortion. The 2010 KHP data was based on the interview from 6,432 households and 19,697 household members. Two part model was used to explore the effects of medication adherence on medical use (logistic regression analysis) and medical expenditures (OLS). Result: Our study result demonstrated that the 74.7% of the patients who strictly adhere to their medication in both years, in 2008 and in 2009, were likely to use inpatient service in 2010. This shows the noncompliant patients were in fact use emergency service less than the compliant patients. Conclusion: Based on our analysis, this paper concludes that the high medication adherence of hypertensive patients could contribute to reduce the emergency service use. Therefore it is highly recommendable for the Korean government and the insurer, NHIS, to actively invest in developing education and promotion program to improve medication adherence among hypertensive patients.

본 연구에서는 한국과 일본의 암검진 사업의 수검율에 영향을 주는 정책적 요인에 대한 융합연구를 통해 분석하였다. 그 결과는 첫째로 국민건강보험제도의 보험자가 단일보험자일 경우 통합적인 암검진 사업이 가능하기 때문에 검진율에 영향을 미칠 것으로 분석되었다. 둘째로 암과 같은 중증질병에 걸렸을 때 예상되는 의료비 부담이 높으면 경제적 인센티브가 작동하게 되어 검진율에 영향을 미칠 것으로 분석되었다. 일본의 경우에는 건강보험에서 보장하지 않는 비급여항목이 거의 없고 본인부담상한제 등이 잘 정비되어 있어 중증질환이라도 의료비부담이 낮기 때문에 암검진의 수검율이 개선되지 않는 측면이 있다. 일본은 건강보험제도의 보장성 강화가 암검진에 대한 경제적 인센티브를 약화시키는 정책적 요인으로 작용한 것으로 나타났다.

Purposes : In February 2014, the government said that the National Health Insurance Service (NHIS) will enforce plan for reducing the financial burden from two major non-covered services including physician surcharges and private room charges, the main causes to increase uninsured, by 2017. The purpose of this study is to analyze the policy effect that performed so far by comparing out-of-pocket payment rates of policy process Methodology: This study analyzed admission medical expenses that occurred from January 2013 to March 2016 at a upper grade general hospitals in Daejeon. Number of study subjects were 134,924 and the data were analyzed with SPSS 22.0 program by using frequency, percentage, mean, standard deviation, ANOVA. The effect of two major non-payment improvement plan on out-of-pocket rates was ascertained via generalized estimating equation. Findings: Out-of-pocket payment rates was statistically significantly declined 2.7 percent than enforcement ago. Also, out-of-pocket payment, physician surcharge, the proportion of out-of-pocket payment of hospital room charge to out-of-pocket payment was statistically significantly declined. However, a further analysis of the cause of the decline in total medical costs is needed. Practical Implications: Physician surcharges and private room charges improvement policy had a positive effect on the decline of out-of-pocket payment rate. The policy of physician surcharges was very effective after the first policy enforcement but it was less effective to medical aids and near poor that was a more greater coverage than national health insurance. Since the policy has not been finalized, we have to continue a research for the successful implementation of the policy.

Purpose: The aim of this study was to determine the perceived needs and confidence of school nurses in health education at middle and high schools in Seoul, Korea. Methods: A descriptive survey questionnaire was developed by a research team to investigate the perceived needs and confidence across eight health education areas. A total of 329 school nurses at secondary schools in the metropolitan areas of Seoul participated. Descriptive statistics, the t-test, and ANOVA were conducted to analyze the data. Results: Generally high means in perceived education needs(Mean: 3.8~4.7/5) and health education confidence (Mean 3.3~4.5/5) were reported. However, there were significantly low means of health education confidence related to perceived needs in health education for all areas of health education. While injury prevention and emergency care education were the highest perceived educational needs and were also areas with high confidence of school nurses, mental health, social health, and sexual health were areas where nurses showed a significantly lower confidence. In general, nurses with a longer clinical experience and educational career had a higher confidence in injury prevention, emergency care, and mental health. Conclusions: Multi-level support, including the continuing education and proactive in-service training, for the school nurses needs to be developed to improve their teaching competency.
