Objectives: The objective of this paper was to estimate a South Korean's lifetime dental expenditures for periodontitis. Methods: For our study, we collected data from the Korea Health Panel Survey (KHPS), from 2010 to 2016. The outpatient dental care data of 1,919,608 samples of periodontitis were extracted using R version 3.0 and estimations of lifetime dental expenditures for them were generated using Excel. Results: Over 50% of the lifetime dental expenditure of South Koreans was spent for periodontitis, and incurred after the age of 40. The results showed that an estimate of average per capita lifetime dental expenditure for men (approximately 13 million won) was greater than that for women (approximately 8.8 million won) for periodontitis. Conclusions: Efficient methods for the prevention and management of periodontitis are necessary, and a new paradigm of health care system is required to reduce dental expenditure through its prevention.

There is a growing need to understand how local, farm household, and elementary units are responding to changes in agricultural conditions due to increased internal and external agrarian conditions and increased uncertainty in agricultural management due to increasing FTA and climate change. Therefore, we analyze dynamics of changes through more detailed and precise gathering of information related to agricultural products and DB, and by analyzing the satisfaction level of the first year panel survey by constructing a producer panel for utilization in agricultural research and policy. A total of 500 farmers in the producer panel who mainly grow rice, garlic, onion, strawberry, apple were collected through questionnaires. The actual analysis used data from a total of 393 farm households, including 82 farms of rice, 51 farms of apple, 100 farms of garlic, 88 farms of onion and 72 farmhouses of strawberry. The distribution by age was similar to the distribution of rural ages in Korea, with 2.8% under 30s, 17.6% in 40s, 32.4% in 50s, 37.5% in 60s and 9.7% in 70s. Panel happiness and rural life satisfaction were examined using the 7 - point Likert scale and the analysis method was one - way ANOVA. The results showed that the happiness of garlic and strawberry cultivator was significantly higher than that of rice and onion cultivator. However, the satisfaction of rural life did not show any difference among the cultivars. As a result of difference verification about Agricultural Outlook and Crop-specific Outlook after 5 years, there was no difference between the crops in terms of prospects for Korean agriculture after five years, but a survey of industrial prospects for crops after five years showed that the rice growers have a significantly negative outlook compared to garlic, onion and strawberry growers, and garlic and onion growers have a more positive outlook than rice and apple growers As a result of verifying whether there is a difference in ages between the agricultural prospects and the industrial prospects by crops after 5 years, there was no difference between the ages of prospects for Korean agriculture after 5 years, However, in the survey on industrial prospects by crops after 5 years, 40s were more positive than 60s.

본 논문에서는 패널조사에서 발생하는 웨이브 무응답을 대체하는 방법을 고찰하였다. 패널조사에서는 이전 조사 데이터를 무응답 대체에 활용할 수 있기 때문에 이러한 성질을 이용하면 횡단면 무응답 대체보다 더 효과적인 웨이브 무응답 대체법을 찾을 수 있다. 먼저 웨이브 무응답 대체를 사용하는 해외의 주요 패널조사를 살펴보고, 웨이브 무응답 대체방법 중 종단면 회귀대체법, 이월대체법, 최근방 회귀대체법, 그리고 행렬대체법을 고찰하였다. 그리고 웨이브 무응답 대체법의 성능을 비교하기 위하여 한국복지패널 데이터를 대상으로 모의실험을 실시하였다. 성능을 비교하기 위하여 평균대체, 회귀대체, 비대체, 최근방 대체, 핫덱 대체를 고려하였고 성능평가 지표로는 예측 정확성 지표와 추정 정확성 지표를 이용하였다. 모의실험 결과 비대체, 행렬대체는 두 지표 모두 우수했고, 회귀대체, 종단면 회귀대체, 이월대체는 예측 정확성은 우수한 반면 추정 정확성은 다소 떨어졌으며, 반대로 최근방 회귀대체, 최근방 대체, 핫덱 대체는 예측 정확성은 떨어지나 추정 정확성은 높은 것으로 나타났다. 마지막으로 평균 대체는 두 지표 모두 좋지 않았다.

본 논문은 사업체패널조사 1차 년도(2005년)부터 6차 년도(2015년)까지의 자료 중 노동자 대표조직, 즉 노동조합이나 노사협의회가 존재하는 사업체를 대상으로 패널 고정효과 모형을 활용하여 경영참여 수준과 사업체의 경제적 성과 간의 관계를 검증해보았다. 분석결과 전기의 경영참여 수준이 높아질수록 일정 수준까지는 당기의 1인당 부가가치(생산성) 및 1인당 인건비(임금)가 상승하다가 그 이후 하락하는 역U자형의 패턴을 확인할 수 있었다. 이는 큰 틀에서 볼 때, 노동자 대표조직의 경영참여 동학에 관한 논리를 제공한 Freeman과 Lazear(1995)의 이론적 예측과 부합하는 결과이다. 이러한 실증분석 결과는 현재 한국의 평균적인 경영참여 수준이 매우 낮으므로, 향후 경영참여의 수준을 지금보다 다소 향상시키더라도 노사공동의 지대, 즉 생산성(1인당 부가가치)을 향상시키는 경제적 성과를 낳을 수 있다는 정책적 함의를 제공해준다.

Objective : In order to understand the scale of medicinal expenditure in the Korean medicine, an analysis has been made of Korean National Health Account and statistic archives used to estimate the Korean National Health Account and also of such archives as are contributory to learn the scale of total health expenditures in the Korean medicine. Method : From the Korean National Health Account archives, an analysis has been made of National health insurance statistic annual reports, National health insurance non-payment items, Korean Economic Census (The Service Industy Survey), and Korea Health Panel data. Moreover, in order to know the sales of overall Korean medicine clinics, relevant data have been utilized and cited from investigations into National tax statistics, Korean medicine medical institutions and Korean medicines used, and current states of medicinal herbs and Korean medicine industry. Results : It is found that the average scale of each section of the medical expenditures archives in the Korean medicine in 2012 was KRW 3.5638 billion and that the average medical expenditures in the Korean medicine derived from Total Health Expenditure, The Service Industy Survey, National tax statistic, and Korean medicine industry are approximately KRW 3.3901, 3.4796, 3.7218 and 3.9634 billion. And the average expenditures derived from National health insurance patients and Korea Health Panel data are 2.5162 and 2.2292 billion won and those from the users and consumers of Korean medicines and herbs are 5.6,461 billion won. In order to verify the appropriateness of estimated medical expenditures in the Korean medicine included in the archives, an analysis has been made of uninsured costs which come from the aggregate sales amount surveyed minus health insurance treatment expenditures and it is found that the ratio of insured costs against total health expenditures in 2006 was 50.67% and 41.92% in 2012 and that the ratio based on National tax statistics and The Service Industy Survey was 52.19% and 49.28% in 2006 and 50.54% and 50.64% in 2012 and that the ratio of uninsured costs against Korean medicines and herbs and Korean medicine industry was 37.5% and 58.27% in 2013. Conclusion : It calls for the improvement of the accuracy of an investigation into Total Health Expenditure which comprise the actual conditions of health insurance and Korea Health Panel, the development of statistic schemes for understanding and classifying medical expenditures of all the Korean medicine medicinal institutions like medicinal clinics, and enhanced methods for independent panels to comprehensively collect and analyze the number of sampled Korean medicine medical institutions.

Objective: To investigate the relationship between the perception of cancer risk and likelihood of having undergone cancer screening. Materials and Methods: We used data from the Korean Health Panel Survey from December 2011 onward. Of 3,390 patients who visited a hospital during the previous year, we included data from 2,466 individuals; 924 samples were excluded due to missing data. Logistic regression analysis and the chi square test were used to investigate the association between perceived cancer risk and the likelihood of having undergone cancer screening. Results: For patients who perceived their risk of developing cancer during the next 10 years to be 30-40%, the odds ratio was increased 1.65 fold (95%CI: 1.223, 2.234) compared with those who perceived their risk to be almost zero. Although the difference was not statistically significant, perceiving cancer risk as either extremely low or extremely high appears to be associated with a reduced likelihood of having undergone cancer screening, resulting in an inverted U-shaped relationship. Conclusions: Physicians and researchers should be aware of the importance of the affective component of risk perception. Policies addressing the influence of cancer risk perception should be implemented in South Korea and worldwide.
