Background: Few studies have examined the performance of the public long-term care insurance (LTCI) from the perspective of geographic equity. This study investigated regional variations and associated factors in the supply and utilization of nursing home care within and also between Japan and Korea. Methods: A comparative dataset was developed by extracting data from 2013-2015 LTCI statistics yearbooks and Organization for Economic Cooperation and Development regional statistics, as well as other comparable data in Japan and Korea. The unit of analysis was the prefecture in Japan and the province in Korea. We computed variation indices and conducted regression analyses for regional variations within each country and decomposition analyses to examine the variations between the countries. Results: The overall regional supply and use of nursing home care were higher in Japan, but the regional variations in Korea were larger than in Japan. In both countries, the nursing home supply was negatively associated with the proportion of older people with independent living. Nursing home use was also negatively associated with the supply of hospital beds and home care agencies in Korea; the relationship was the opposite in Japan, however. The country-based differences were more likely to be explained by differences in the distributions of the variables included in the analytical model than country-specific characteristics. Conclusion: Regional-level nursing home supply and use were unequal in both countries, and the contributing factors were not the same. Policy efforts are needed to advance regional equality in long-term care (LTC) and collaboration between health and LTC institutions for frail older people, especially in Korea.

The purpose of this study is to develop the PTC Heater element for early fuel evaporator in Multi point injection system in order to reduce the harmful exhaust gas at the cold start stage. In order to do this, we fabricated three type of PTC Heater element, the Curie temperature of which were 80℃, l20℃, 180℃ and then checked the electrical property. The resistances of the three type of PTC Heater element, the Curie temperature of which were 80℃, 120℃, 18 0℃ were 3.12Ω, 10.7Ω, 3.85Ω and their resistance increase ratio were 4.07 order, 4.23 order, 4.43 order, respectively.

The purpose of this study is to evaluation the fuel evaporntion by the injection of the fuel to the high tempernture surface heated of PTC Heater for early fuel evaporntion at the cold start stage in gasoline engine. In order to do this, we checked electrical control injection system and then made the experimental equipment so that tested the performance of PTC Heater. The injection angle for MPIS was 24˚and the avernge droplet diameter was 300㎛. The heater will be installed 70mm below the injector, so that the area of the heated zone should be wider than that of a circle with 30mm diameter. During the heating experiments of the injected fuel, the best condition for efficient evaporntion was drawn, that is, Curie temperature of 180˚C and the impinging angle of 90˚.

We studied the acquistion of basic data through the purchase of the Early Fuel Evaporator PTC Heater by Texas Instrument in order to manufacture teclmology of PTC Heater for Early Fuel Evaporator in multi point injection system. In order to do this, we investigated to the outward shape of the PTC Heater for Early Fuel Evaporation in multi point injection and then to the size, electrical properties, microstructural characterstics, chemical analysis for the PTC Heater element which was pulled out from PTC Heater for Early Fuel Evaporation.
노인의 실내 유해물질 노출관련 행태와 건강의 관계: 가구행태를 중심으로

급격한 노령화에 따라 우리나라 노인가구의 형태가 빠르게 변화하고 있으며, 특히 독거노인 가구를 포함한 노인 단독가구가 주요한 가구형태로 자리잡고 있다. 가구형태가 한국 노인 건강에 미치는 영향에 대한 연구는 많으나 실내 물리적 환경에 주목한, 학술 지에 발표된 연구는 매우 적다. 이 연구의 목적은 노인들의 가구형태와 실내 유해물질 노출관련 건강행태의 양상을 살펴보고 가구형태와 실내 유해물질 노출관련 행태 및 건강의 관계를 살펴보는 것이다. 분석 대상은 국립환경과학원의 노령환경코호트 II 1차년도 자료 중 60세 이상의 지역사회에 거주하는 735명이다. 연구 결과, 독거노인은 자녀동거 노인에 비해 우울감을 경험할 가능성이 높았다. 실내 유해물질 노출 양상을 보여주는 변수인 겨울철 환기 시간과 유해 난방연료의 사용은 우울감과 유의한 상관성을 보였다. 또한, 다변량 회귀분석에서 가구형태의 효과를 보정한 후에도 실내 유해물질 노출과 우울감은 유의한 양의 상관관계가 있었다. 이 연구의 결과는 우리나라의 가구형태와 가족가치관이 변화하였으나 전통적인 가구형태에 내재되어 있는 가족 간의 유대관계는 노인의 건강에 중요한 보호요인으로 작용함을 시사한다. 또한 노인의 실내 유해물질 노출관련 행태가 구형태에 따라 달라져 건강영향으로 나타날 수 있어, 노인건강증진에 있어 실내환경과 건강에 대한 보다 심층적인 추후 연구가 필요하다. The change in the Korean population structure over time have resulted in an increasing proportion of the elderly, which led to changes in living arrangements. It is widely known that the living arrangements of the elderly affect health outcomes, but the pathways of how this association occurs are still unclear. The purpose of this study is to examine the effects of older Koreans` living arrangements on their environmental exposures and health outcomes. This study supposed that living arrangements of older Koreans contribute to environmental exposure related behavior and health outcomes. Higher environmental exposures level was associated with lower self-rated health and higher depressive symptom. The relationship between living arrangements and health outcomes in consideration of indoor environmental exposures presented elderlies living alone showed lower health outcomes than those living with child. While considering for living arrangements, higher environmental exposures level were associated with lower self-rated health and higher depressive symptom. This study showed the social support factors underlying in traditional living arrangement significantly affected the health status of the elderly. The social support underlying in traditional living arrangement was significantly associated with indoor environmental exposure related behavior and health outcomes.
