What Drives the Increase of Health Care Expenditures for the Elderly?
( Siyeon Ju ),( Jieun Song ),( Kyoungsun Park ) 한양대학교 경제연구소 2021 JOURNAL OF ECONOMIC RESEARCH Vol.26 No.3
This paper examines the driving forces behind the recent increase in health care expenditures (HCE) for elders, using the Korea mandatory health insurance data over 2004-2018 together with the Korean Health Panel (6-12<sup>th</sup> waves). Our findings are two-fold. First, decomposing the total HCE into three factors, a demographic factor (the number of the elderly) and two non-demographic ones (the frequency of health care utilization and the price of medical treatments), we find that their relative contribution to the annual HCE increase accounts for 38.5%, 22.0%, and 39.5%, respectively. Second, from our two-part regression of time-to-death and age on the HCE growth, we find that proximity to death is a key force even after controlling for aging, morbidity, and income. These two results jointly imply that the HCE growth for the elderly has been accelerated by rising health care price and intensifying treatment particularly near to one’s end-of-life as well as the population aging.

The Effect of Social Capital on Medical Care Use by the Elderly : The Concept of Health Congruence
주시연(Siyeon Ju),임재영(Jae-Young Lim) 한국자료분석학회 2018 Journal of the Korean Data Analysis Society Vol.20 No.1
It is widely known that the medical cost for the elderly severely threatens the stability of national health insurance system. We investigated the impact of social capital on the medical care use by the elderly. The concept of health congruence, the conformity between objective and subjective health status, was used as a mediator affected by the social capital, and determines the medical use of the elderly in turn. Respondents from HAPS (Hallym ageing panel study) data were separated into healthy and unhealthy group by their objective health status, and subdivided into congruent (good and poor health realist) and incongruent (good health pessimist and poor health optimist) group by whether their health congruence had been achieved. After controlling for socioeconomic, health-related, and supplier-related variables, health congruence turned out to influence the efficiency of medical care use regardless of the health status, and social capital improves healthy elderly’s health congruence, which prevents unnecessary visit to medical institutions. Nevertheless, we should thoroughly take the level of social capital and features of subject into consideration before adopting social capital as a policy instrument aimed for the elderly.

Time constraint is one of the most important disadvantages for care-givers within households since care-giving is time-intensive work. Less freedom of care-givers due to time constraints at present may also lead to less freedom in the future since time-use at present may be the basis for capability in the future. In this context, this study will examine the time metrics of care-giving within the Korean households from the perspective of freedom. It will try to answer, first, who give care to the family members in need of care, and secondly how caregivers spend time in terms of care-giving and other activities of daily life such as work, and leisure. This study will approach to these questions from the viewpoint of human capability, and will use data from the Korean Time-use Survey in 2004. This paper argues that care-givers are faced with ‘care-trap’ which gives care-givers not only time disadvantage at present but also constraints on capability accumulation for the future. Regarding female care-givers, those who spend more time on care do more housekeeping work. This further reduces their opportunity freedom.

Four-Neutrino Analysis of 1.5<i></i>km Baseline Reactor Antineutrino Oscillations
Kang, Sin Kyu,Kim, Yeong-Duk,Ko, Young-Ju,Siyeon, Kim Hindawi Limited 2013 Advances in high energy physics Vol.2013 No.-
<P>The masses of sterile neutrinos are not yet known, and depending on the orders of magnitudes, their existence may explain reactor anomalies or the spectral shape of reactor neutrino events at 1.5 km baseline detector. Here, we present four-neutrino analysis of the results announced by RENO and Daya Bay, which performed the definitive measurements of<SUB>θ13</SUB>based on the disappearance of reactor antineutrinos at km order baselines. Our results using 3 + 1 scheme include the exclusion curve ofΔm412versus<SUB>θ14</SUB>and the adjustment of<SUB>θ13</SUB>due to correlation with<SUB>θ14</SUB>. The value of<SUB>θ13</SUB>obtained by RENO and Daya Bay with a three-neutrino oscillation analysis is included in the1σinterval of<SUB>θ13</SUB>allowed by our four-neutrino analysis.</P>

직접시공 확대의 영향 분석 및 직접시공의무제도 적용을 위한 대응방안 제언
이미성,김시연,유일한,한주연,손정욱,Lee, Meesung,Kim, Siyeon,Yu, Ilhan,Han, Ju-yeon,Son, JeongWook 한국건설관리학회 2021 한국건설관리학회 논문집 Vol.22 No.6
As the construction production system is reorganized as part of the construction industry innovation plan, direct construction is expanding. According to this trend, this study analyzed the impact and problems of the expansion of direct construction through the position of the construction industry and a study of foreign cases. In addition, by diagnosing the impact of the measures to expand direct construction from various aspects, countermeasures were suggested to suitably apply the direct construction mandatory system. Also, for each alternative, effects and problems were evaluated through interviews with experts in policy/administrative and architecture fields. The alternatives for expanding and improving the efficiency of the direct construction mandatory system derived from this study are four items: granting the discretion of the client, differentiation by scale of construction, utilization of construction guarantee system, and introduction of flexible working group leader system. As a result of the expert interview, all of them were evaluated to have a positive impact directly and indirectly on the expansion of direct construction. This study contributes literature to the application of the direct construction mandatory system by examining the current status of direct construction, and suggests a direction for expanding direct construction through deduction of alternatives for applying the direct construction mandatory system and expert evaluation. 건설산업 혁신방안의 일환으로 건설생산체계가 개편됨에 따라 직접시공이 확대되고 있는 추세이다. 본 연구는 이러한 추세에 따라 직접시공 확대의 영향 및 문제점을 건축관련 업계의 입장과 외국 사례 조사를 통하여 분석하고 직접시공 확대 조치에 따른 영향을 다양한 측면에서 진단하여 직접시공의무제도를 바람직하게 적용하기 위한 대응방안을 제언하였다. 또한, 각 대안에 대하여 정책/행정 및 건축 분야 전문가 인터뷰를 통하여 효과 및 문제점을 평가하였다. 본 연구에서 도출된 직접시공의무제도 확대 및 효율화를 위한 대응방안은 발주자의 재량권 부여, 공사규모에 따른 차별화, 건설보증시스템 활용, 탄력적 작업반장제 도입의 4가지로, 전문가 인터뷰 결과 모두 직접시공 확대에 직간접적으로 긍정적 영향을 줄 것으로 평가되었다. 본 연구는 직접시공 현황을 조사하여 직접시공의무제도 적용에 있어 기초자료를 제공하며 또한 적절한 직접시공의무제도 적용을 위한 대응방안 도출과 이에 대한 전문가 평가를 통하여 직접시공 확대를 위한 방향을 제시함으로써 결과적으로 합리적 직접시공의무제도 운영을 통한 건설기업과 현장의 생산성 향상 및 효율화에 기여할 것으로 기대된다.
