Background: The purpose of this study is to investigate family caregivers' opinions about out-of-pocket payment for long-term care (LTC) facilities, and find the differences in the opinions for family caregivers of all different levels of income. Methods: We used the data of the study on out-of-pocket payment in national long-term care insurance, including 1,552 family caregivers with the elderly in long-term care facilities. Results: The average out-of-pocket payment per month was 511,635 Korean won and distributed from 230,750 to 1,365,570 Korean won. The amount of out-of-pocket payment might be affected by not co-payment but the cost of non-covered service. There were differences in them for family caregivers of all different levels of income. Opinions were surveyed about 5 issues. By levels of income, there were differences in their opinions about 3 issues, the financial burden on LTC, the necessity of reducing out-of-pocket payments, and to be willing to pay more for a high quality service. But there were not different opinions about the interruption of LTC service and staying with LTC facilities. Conclusion: These findings suggest that the range of out-of-pocket payment for LTC facility is wide and it can be a burden to lower income group. It should be to prepare the policies to ease the financial burden and support the appropriate LTC use.

Purpose: The purpose of this manuscript is to discuss the need for use of evidence based practice (EBP) in LTC, the current use of evidence in long term care facilities and what we know about adoption of the use of EBP in LTC. Methods: Literature review and reporting of findings from the M-TRAIN study that was a quasi-experimental design to test the effectiveness of an intervention to increase the use of EBPs for urinary incontinence and pain in 48 LTC facilities. Results: Barriers to adopting EBPs include lack of available time, lack of access to current research literature, limited critical appraisal skills, excessive literature to review, non-receptive organizational culture, limited resources, and limited decision-making authority of staff to implement change. Strategies to promote adoption of EBP include the commitment of management; the culture of the home; leadership; staff knowledge, time, and reward; and facility size, complexity, the extent that members are involved outside the facility, NH chain membership, and high level of private pay residents. Findings from the M-TRAIN add, stability of nurse leader and congruency between the leaders perception of their leadership and the staff's perception of the leadership. Conclusion: There is clear evidence of the need and the benefits to residents of LTC and to the health care system yet adoption of EBP continues to be slow and sporadic. There is also evidence for the process of establishing best evidence and many resources to find the available EBPs. The urgent need now is finding ways to best get the EBPs implemented in LTC. There is growing evidence about best methods to do this but continued research is needed. Clearly, residents in LTC deserve the best care possible and EBPs represent an important vehicle by which to do this.

The purpose of this study was to investigate the effect of calcium hydroxide and glass ionomer cement fillings on the levels of $LTB_4$ and $LTC_4$ in experimentally inflamed rat dental pulp. The dental pulp in the mandibular incisor of wistar rat was irritated by cutting a 5mm deep hole in the dentin with a twist drill bur of 0.5mm diameter, without cooling. The cavities were filled with calcium hydroxide(light-cured) and glass ionomer cement(light cured). The untreated pulp served as control tissue specimen. After cavity preparations, the rat with or without various treatment were sacrificed in various time by decapitation. The dental pulp tissue were carefully removed and the concentrations of $LTB_4$ and $LTC_4$ were determined by radioimmunoassay. And pulps were examined histologically to observe inflammatory feature. The result were obtained as follows : 1. The inflammatory features of pulps were observed microscopically in all experimental groups. And degree of inflammation was decreased with time. 2. The concentrations of $LTB_4$ and $LTC_4$ for all experimental groups were significantly higher than those for control group 6 hours after cavity preparation(p<0.05). 3. The group filled with calcium hydroxide was the lowest, and the group filled with glass ionomer cement, the group of irritation in that order showed increased concentrations of $LTB_4$ and $LTC_4$ 6 hours after cavity preparation. In the concentrations of $LTB_4$, significant differences among 3 groups were noted(p<0.05). 4. The group filled with calcium hydroxide was the lowest, and the group filled with glass ionomer cement, the group of irritation in that order showed increased concentrations of $LTB_4$ and $LTC_4$ 24 hours after cavity preparation. And there were statistically significant difference in concentrations of $LTB_4$ between the group of irritation and the group filled with calcium hydroxide(p<0.05). 5. The group filled with calcium hydroxide was the lowest, and the group filled with glass ionomer cement, the group of irritation in that order showed increased concentrations of $LTB_4$ and $LTC_4$ 48 hours after cavity preparation. But no statistically difference was found (p>0.05). 6. The concentrations of $LTB_4$ and $LTC_4$ in all experimental groups were highest level at 6 hour after experiment and decreased as time progresses(correlation coefficient>0.8).

신호교차로에서의 효율적인 교통운영을 위해서는 비보호좌회전의 활성화가 필요하며 이를 위해서는 비보호좌회전이 허용되는 신호교차로에서의 교통운영의 정확한 분석이 가능해야한다. 본연구에서는 국내신호교차로에서의 운전자의 행태에 기초하여 USHCM의 비보호 좌회전 분석에서 요구되는 $g_f$, $g_q$, $P_L$, 의 현실적인 값을 산정하기 위한 모형이 제안되었으며 이에 기초하여 비보호좌회전 보정계수 및 용량분석 기법을 제시하였다. 본 연구의 결과는 다음과 같다. 첫째, 공용차로를 가진 비보호좌회전 신호교차로에서 주기당 좌회전교통량(LTC)이 5대까지의 범위에서 G(녹색신호시간)와 LTC를 변수로 한 $g_f$모형이 개발되었다. 둘째, $v_{olc}$와 $qr_o$를 변수로 한 $g_q$모형이 개발되었으며 제안된 모형에 의한 $g_q$값이 진주 및 광주에서의 현장관측치와 거의 일치함을 볼 수 있었다. 셋째, 1994 USHCM의 $P_L$모형이 LTC가 증가할수록 $P_L$값이 감소하는 비현실적인 모형의 구조를 가지므로 현실적인 모형의 구축을 위해 국내 현장자료에 기초하여 LTC를 변수로하여 $P_L$산정을 위한 단순화된 모형이 개발되었다. 넷째, 대향교통류를 통해 좌회전할 수 있는 유효녹색시간의 부분의 $g_u$를 산정하여 비보호좌회전 포화교통류율($S_{LT}$)에 주기 대 $g_u$의 비를 곱한 비보호좌회전 용량산정식이 제안되었다.

Purpose: This is a comparative study using secondary data from the Korean national long term care (LTC) insurance. Methods: Visiting nursing (VN) service users (n=666) and non-users (n=4,375) were extracted and compared in terms of medical expenditures, length of hospitalization, and annual number of ambulatory care visits to investigate effects of VN services in LTC. Results: Total health care expenditures were compared between the two groups and it was found that VN service users spent about $ 1700 than non-users for their medical costs between 2009 and 2011. The average length of in-hospital stay for VN service users was 19.4 days shorter than that of non-users. However, using VN services did not significantly influence the annual number of ambulatory care visits. Conclusion: The study has found that VN services are effective ways of providing community-based LTC services. We recommend LTC policy makers to further utilize VN services to deliver cost effective health care services.

Purpose: The purpose of this study was to explore the barriers and solution of providing long-term care (LTC) services at home for the beneficiaries with mild dementia. Methods: The data were collected by interviewing three focus groups consisting of 10 home-visit nurses and analyzed through the analytic process by Morgan and Krueger. Results: The barriers of providing LTC services for clients were identified as follows: inadequateness of the current LTC model for elderly individuals with mild dementia and inappropriateness of the personal environment for home care. The solutions for these barriers were suggested as follows: building up a safe environment for home care and maintaining an appropriate standard utilization plan of LTC service. Conclusion: The current service model for the beneficiaries with mild dementia should be modified in order to provide comprehensive long-term care services based on their complex needs.

Purpose: This study aims to provide basic data for the development of measures and promoting home health nursing by examining the current status and trends in home health nursing for long-term care (LTC) insurance beneficiaries. Methods: Secondary data, including annual LTC insurance statistics reports for 2010-2017 and LTC manpower data, were used to compute current status and trends in the provision of home health nursing. Results: Beneficiaries of home health nursing under LTC insurance, insurance-covered costs for home health nursing, home health nursing provider, and home health nursing providing institution only accounted for 3% of all insurance-covered home care services, and were on a consistent decline since 2010. In particular, vulnerable rural regions with high proportion of individuals had poor infrastructure in terms of home health nursing institutions and manpower, but had a higher home health nursing utilization rate compared to urban regions. Conclusion: In addition to measures to support home health nursing service beneficiaries, policy measures are needed to support home health nursing service personnel and institutions. Furthermore, programs to cultivate the expertise of home health nurses and improve quality of home health nursing services should be developed in order to promote home health nursing utilization in vulnerable rural regions.

Integrated performance test of Chemical and Volume Control System (CVCS) was successfully performed in 1994. However, an extensive effort to correct hardware and software problems in the letdown line was required mainly due to the lack of adequate simulation code to predict the test accurately. Although the LTC computer code was used during the YGN 3'||'&'||'4 NSSS design process, the code can not satisfactorily predict the test due to its insufficient letdown line modeling. This study developed a numerical model to simulate the letdown test by modifying the current LTC code, and then verified the model by comparing with the test data. The comparison shows that the modified LTC computer code can predict the transient behavior of letdown system tests very well. Especially, the model was verified to be able to predict the "Stiction" phenomena which caused instantaneous fluctuations in the letdown backpressure and flowrate. Therefore, it is concluded that the modified LTC computer code with the ability of calculating the "Stiction" phenomena wi11 be very useful for future plant desist and test predictions.predictions.
