The purpose of this study is to investigate evaluation and improvement of long-term care hospitals for changing long-term care hospitals fee system. Data were collected from 104 CEOs in nationwide long-term care hospitals using structured self-administered questionnaires during August 17 to 31, 2009. Major results of the empirical analysis are as follows; first, to change fixed sum medical fee per day caused to decline the level of geriatric service in 87% of CEOs. Second, 79% of CEOs were dissatisfied with changing fixed sum medical fee per day, and 47% of them were dissatisfied with graded fee for doctor and nurse management. Finally, they suggested that to specialize and to differentiate of long-term care hospitals will drive to improve long-term care hospitals function and to measure workforce based on rate of filled vacancies will increase efficiency and productivity of doctor and nurse management.

The pipe with a long-neck flange is widely used in power plants, chemical plants, and shipbuilding companies. New the pipe with a long-neck flange is manufactured by welding a thick flange to a pipe. But this long-neck flange pipe has some deflects in the welding region such as unfitting and local thermal fatigue, which weaken the strength around the neck of the flange. Moreover, after welding the flange, the contacting surfaces of the flange have to be machined flat. So, that is uneconomical. Therefore, to solve the above problems of the long-neck flange pipe, a new process, which has no defects around the flange neck, is required. In this study, three forming processes are suggested to get an enhanced long-neck flange. First suggested process consists of conical terming and flange forming. Second and third suggested processes consist of the bulging of a long pipe locally heated by induction coils and the flange forming. The differences between second and third suggestions are the thickness and local heating area of the pipe. That is, the thickness of the initial pipe of third suggestion is larger than that of the final product, and the local heating area is smaller than that of second suggestion. These three suggestions fur forming a long-neck flange are simulated by FE analyses with a commercial cede DEFORM 2D. Especially, the theoretical result of FE analysis on the first suggestion fur forming a long-neck flange is verified by the experiment with aluminum 6063 pipes. From the theoretical and experimental results, it is concluded that three suggested processes are very useful in order to manufacture the pipe with a long-neck flange without any deflects.

Background: This study examined patient and hospital factors related to long-stay admissions in long-term care hospitals (LTCHs) among older people in Korea. Methods: We analyzed health insurance claims data, entitlement data, and institutional administrative data from the National Health Insurance Service databases between 2010 and 2012. At the patient level, we compared characteristics of patients staying in LTCHs for over 180 days (the long-stay group) with those staying in LTCHs for less than 90 days during a calendar year. At the hospital level, we examined the general characteristics and staffing levels of the top 10% of hospitals with the highest proportion of patients whose length of stay (LOS) was 180+ days (the hospitals with long-stay patients) and compared them with the top 10% of hospitals with the highest proportions of patients whose LOS was less than 90 days (hospitals with shorter-stay patients). Results: The long-stay group accounted for about 40% of all LTCH patients. People in the group were more likely to be women, aged 80+, living alone, and experiencing more than two health conditions. Compared to the hospitals with shorter-stay patients, those with long-stay patients were more likely to be occupied by patients with behavior problems and/or impaired cognition, owned by corporate or local governments, have more beds and a longer period of operation, and deliver services with lower staffing levels. Conclusion: This study found long-stay older people in LTCHs and those in LTCHs with high proportions of long-stay older patients had several distinct characteristics compared to their counterparts designated in this study. Patient and hospital characteristics need to be considered in policies aiming to resolve long-stay admissions problems in LTCHs.

The purpose of this study was to analyze the level of the cognitive function and activities of daily living of the beneficiary older adults at home based on Korean Long-term Care Insurance System. A cross-sectional descriptive survey was conducted from November 2010 to May 2011, the final respondents were 1,026 beneficiary older adults taking home visit care covered in Korean long-term care insurance system. The questionnaire included general characteristics of subjects, cognitive function, ADL(Activity of daily living). The data was analyzed using the SPSS 20.0 version. There was significant difference in cognitive function and ADL between 1st Grade, 2nd Grade and 3rd Grade of long-term care classification. The correlated factors of cognitive function were ADL, long-term care grade, disability of arm and leg, limitation of joint, bed sore and tube feeding. The correlated factors of ADL were cognitive function, long-term care grade, disability of arm and leg, bed sore and tube feeding. This study suggests that cognitive functions have to be mainly considered in long-term care grade. It is necessary to make an effort to develop long-term care grade in Korean long-term care insurance system an cognitive function improvement program for the beneficiary older adults. Above all things government will be seriously contemplating of revise contents for long-term care grade to provide quality of care for the older adults.

Background: In 2008, Korea implemented a new type of social insurance known as "long-term care insurance". We examined the association between ownership of long-term care facilities and the incidence of pressure ulcers after the implementation of "long-term care insurance". This study is a population-based retrospective cohort study from 2006 to 2013. Methods: We used medical claims data from the Korean National Health Insurance Corporate Elderly Cohort Database from 2006 to 2013. These data comprise a nationally representative sample. To avoid confounders, only patients admitted to one long-term care facility and who stayed for >70% of the follow-up time were included; as a result, 3,107 individuals were enrolled. The main independent variable was the operating entity of the long-term care facility (local government, corporate bodies, and private for-profit owners), and the dependent variable was the 1-year incidence of pressure-ulcers. Survival analysis (Cox proportional hazard model) was used as an analysis method. Results: Compared to patients admitted to local government long-term care facilities, patients admitted to private long-term care facilities had a significantly higher 1-year risk of pressure ulcers (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.29-2.91); the risk was especially high among patients who were cognitively dependent (HR, 2.34; 95% CI, 1.25-4.37). Conclusion: Patients admitted to private for-profit long-term care facilities were more likely to have pressure ulcers compared to those in local government and corporate body long-term care facilities. Appropriate assessment tools and publicly available information, as well as more restricted legal requirements, are needed to improve the care quality and outcomes of patients in long-term care facilities.

Before introducing the national long-term care insurance in 2008, the want for long term care service has to be estimated and analysed. This study estimates the demand and analyses what determines the want of long term care service. This study investigated data of 3f6 elderlies, that was collected by age stratified random sampling. The elderies resided in Onyang 4 - dong (urban area) and Dogo-myun (rural area) In the city of Asan. The researchers visited the elderlies and their care giver, and assessed their demand for the long term care service and examined physical, mental, socio-economic status by the assessment tools for Korean Long-Term Care System. $64\%$ of the those who are entitled to be served refuse the long term care service. $26.7\%$ of them wants for home care service and $7.9\%$ want facility care service. It is estimated that the want of home care service are three or four times as much as that of facility care service. The demand for long term care service is 5.155 times higher for those who live in rural area (p=0.000), 3.040 times higher for those who do not have spouse(p=0.057), and 3.356 times higher for the people who is in medicaid than medical insurance(p=0.029). However, income(p=0.782), means(p=0.614), living alone(p=0.223), number of family to live with (p=0.341) and age of the elderly(p=0.420) are not related with the demand of long term care service. The assessment tools for Korean Long-Term Care System for need evaluation of the long term care service can reflect the demand well.(p=0.024) If medical care will cover $80\%$ of total cost, the willingness to pay of the out of pocket money of the people with medical insurance is 67,400 Korean Won(66.77 US$) for the home care service and 182,500 Korean Won(180.78 US$) for the facility care service. There is possibility that long term care demand is still small after Introducing the long term care Insurance due to the care given by family members. When developing service delivery system of long term care insurance, rural area has to be given more consideration than urban area because of the higher demand. The people who do not have spouse or are in medicaid have to be given special consideration as well.

Purpose: The purpose of this study was to identify and compare the differences on perceived health status, Activities of Daily Livings (ADL), social support, and residential satisfaction between long-term care hospitals and nursing homes. Methods: Data was collected through questionnaires and interviews conducted from March 29 to April 22, 2011. The subjects were 66 old adults in 3 long-term care hospitals and 53 old adults in 6 nursing homes. Data were analyzed by Pearson's correlation analysis and t-tests. Results: ADL and subjective health status in nursing homes were worse than those in long-term hospitals, but it was not statistically significant (p>.05). Old adults in nursing homes received more emotional support from other residents and staff, and received more instrumental support from staff than those in long-term care hospitals (p<.001). The mean scores of resident satisfaction in long-term care hospitals and nursing homes were 3.53 ($SD={\pm}0.36$) and 3.97 ($SD={\pm}0.44$), respectively. Resident satisfaction in nursing homes significantly was higher than long-term care hospitals (p<.001). Conclusion: Health care personnels in long-term care hospitals should enhance resident satisfaction and social support and need to coordinate long-stay patients with nursing homes.
