Background: This study aims to analyze the impact of levels of health care coverage on the trajectory of self-rated health, comparing the near-poor which tends to be excluded in traditional health care systems with the upper middle class. Methods: The study participants were 3,687 people who sincerely responded questions regarding health care expenditures, unmet medical needs, and self-rated health in the Korea Health Panel data in 2009-2012. Results: The higher health care expenditures and the presence of unmet medical needs were significantly associated with the lower level of self-rated health. However, both factors did not significantly predict the steeper decline in the self-rated health. The results from multiple group analyses showed that health care expenditures and unmet medical needs had greater impact on the near-poor compared to their higher income counterparts. Conclusion: Public health care coverages need to be enhanced as well as reducing health care expenditures and unmet medical needs.

In this paper, to estimate the location of underwater robots using RF (Radio Frequency) sensor was examined whether the possibility of application in the underwater environment. Typically, RF sensors which used in network communication can estimate distance between each nodes by using RSSI(Received Signal Strength Indicator) method. As a result, it is one of the methods as a localization system for robots. RF signal generate large noise in the air due to random obstacles and thermal conditions, hence it can occur large errors. But in the underwater environment, RF generate small noise relative to the air environment, although its signal power reduce seriously by extending both sensors distance. Despite of the defect, a precise short distance localization and limited area localization can be adaptable. In underwater environment, available detecting length will be limited, but the attenuation of specific distance has very uniformity characteristics. In this paper, we examine the characteristics and verify the possibility as a short distance underwater localization system with various experiments.

보훈의료 대상자는 다른 보험가입자에 비해 고령인구 비율이 높으며 70세 이상이 전체의 60.2%를 차지하고 있다. 이에 정부는 보훈의료비 예산을 지속적으로 증액하고 있으나, 참전보훈 대상자의 급감, 중장기복무 제대자의 증가 등으로 보훈의료비의 예측정확도가 떨어지고 있다. 본연구의 목적은 보훈예산의 효율적 운영과 장기예측을 위해 보훈의료 대상자별 의료이용 특성을 반영한 의료비 산정체계를 개발하는 것이다. 연구방법으로는 추세분석모형, 이동평균모형, 기하 평균모형을 사용하였고, 보훈의료비 예산총액모형과 연인원, 진료단가의 세부항목으로 구성된 추계모형을 개발하였다. 추계모형의 예측정확도는 평균절대오차율(MAPE)로 판별하였고, 그 중 정확도가 가장 높은 모형을 산정체계로 선정하였다. 자료는 2007∼2018년 국가보훈처의 보훈의료비 예결산 자료를 이용하였다. 분석결과, 시계열자료를 토대로 분석한 추세분석모형의 예측정확 도가 가장 높게 나타났고, 기하평균모형과 이동평균모형은 상대적으로 낮게 나타났다. 이러한 결과는 보훈의료비 지원제도와 대상자 구분 정책의 큰 변동, 지불제도의 특성 때문에 나타난 것으로 판단되므로 안정적인 보훈의료비 지원제도와 감면제도의 확립, 기존의 행위별수가제에서 총액제로 지불제도를 변경하는 제도개선방안을 제안하였다. The veterans are considered to have the highest elderly population among the health insurances in South Korea. The government continues to increase the veterans medical expense budget. However, the forecasting accuracy of veterans medical expenses is declining due to an abrupt decrease in the number of war related veterans and an increase in the number of long-term service veterans. The purpose of this study is to develop a medical expense estimation system that reflects the special characteristics of the veterans. Trend analysis model, moving average model, and geometric average model were used as forecasting models. Estimation methods for each budget item were developed by applying the total amount estimation and component estimation. The estimation accuracy was calculated by mean absolute percentage error. The model with the highest accuracy was selected as the calculation system. As a result, the trend analysis model showed the highest estimation accuracy. Factors that decrease the forecast accuracy include the frequent changes in the veterans’ medical expense system, patients classification policy, and payment system. This study suggests to establish a stable system of veterans’ medical expenses and to change the payment system from fee-for service to global budget system to improve veterans’ medical expenses estimation accuracy.

비정규직 근로자는 경제, 주거, 건강, 사회관계, 노동 등 다양한 측면에서 배제를 경험하게 되는데, 기존의 선행연구들은 다차원적 사회적 배제와 건강과의 관계를 실증적으로 살펴보지는 못하였다. 따라서 본 연구는 비정규직 근로자의 다차원적 사회적 배제가 그들의 건강에 미치는 영향을 주관적 건강과 우울상태에 초점을 두고 살펴보았다. 본 연구는 2006년부터 2016년까지 한국복지패널에 포함된 정규직과 비정규직 근로자 2,585명을 대상으로 비정규직 여부와 다차원적 사회적 배제가 비정규직 근로자의 주관적 건강과 우울상태의 변화에 미치는 영향을 종단적으로 검증하였다. 분석결과 비정규직 근로자의 주관적 건강상태는 시간의 흐름에 따라 큰 변화가 없고, 우울상태는 초기에 비해서 완화되는 형태로 변한다는 것을 알 수 있었다. 다음으로, 정규직에 비해 비정규직 근로자의 초기 주관적 건강과 우울상태나 나쁘나, 그 차이가 시간의 경과에 따라 다소 감소하는 경향을 보였다. 마지막으로 다차원적 사회적 배제가 포함된 분석모형에서는 미충족의료와 직업에 대한 만족도가 비정규직 근로자의 주관적 건강의 초기값에 영향을 미치는 것으로 나타났다. 우울의 경우 경제생활, 주거환경, 가족관계, 직업만족도, 건강보험미납 그리고 미충족의료가 초기값에 영향을 미치는 것으로 나타났다. 하지만 다차원적 사회적 배제 변수들은 주관적 건강과 우울상태의 변화율에는 큰 영향을 미치지는 못하였다. 이상의 내용을 토대로 비정규직 근로자의 건강을 위한 다차원적 사회적 배제의 완화방안에 대하여 논의하였다. Atypical worker have been excluded in many ways from economy, housing, health, social relations, and labor opportunities. However, few studies have empirically tested the relationship between multidimensional social exclusions and health. In this respect, this study aims to identify the relationship between multidimensional social exclusions and atypical worker`s health, focusing on their self-rated health and depressive symptoms. In particular, this study longitudinally examine the impact of employment status and multidimensional social exclusions on self-rated health and depressive symptoms. The data contains a total of 2,585 typical and atypical workers drawn from the Korean Welfare Pane l(2006 - 2016). Among the findings of the data analysis is that atypical workers` self-rated health has not changed to a significant extent, while their depressive symptoms have substantially decreased over time. In addition, initial gaps in self-rated health and depressive symptoms between typical and atypical workers tend to slowly decline over time. Finally, results from the model including multidimensional social exclusions presented that unmet health care needs and job satisfaction significantly predicted self-rated health in baseline. For the intercept of depressive symptoms, economic satisfaction, housing, family relations, job satisfaction, unpaid health insurance and unmet health care needs were significant predictors. However, multidimensional social exclusions did not significantly predict the rate of changes in self-rated health and depressive symptoms. Based on these findings, this paper discussed how to reduce the impact of multidimensional exclusions for better health of atypical workers.
