Purpose: This study empirically investigates the utilization and expenditure of health care and long-term care at the last year of life for long-term care beneficiaries in Korea. Methods: This study used National Health Insurance and Long-term Care Insurance claims data of 271,474 LTCI beneficiaries, who died from July 2008 to December 2012. Their cause of death, place of death, health care costs, and the provision of aggressive care were analyzed. Results: Cardio-vascular disease(29.8%) and cancer(15.3%) were reported as their major cause of death, and hospital(64.4%), home(22.0%), social care facility(9.2%) were analyzed as the place of death. 99.3% of subjects used both health care and long-term care during the last 1 year of life. The average survival period were 516.2 days after they were LTCI beneficiaries. The health care expenditure gradually increased near the death, and the last month were three times more rather than the first month. Furthermore, 31.8% experienced some aggressive cares(CPR, blood transfusion, hemo-dialysis, etc.) at the last month of life. Conclusion: The results of this study suggest that it is important to develop the end of life care policies(for example, hospice, advanced care directives) for the LTCI beneficiaries. They might contribute to the improvement of quality of life and the reduction of health care expenditure of the elderly at the end-of-life.

Purpose: This study was done to examine good death awareness, attitudes toward advance directives (ADs), and preference for care near the end-of-life (PCEOL) of hospitalized elders in long-term care hospitals. Relevant characteristics were investigated as well as correlation of the variables. Methods: This descriptive research study involved 161 hospitalized elderly patients in long-term care hospitals. A self-report questionnaire was used to measure Good Death Scale, ADs Survey, PCEOL Scale, and general characteristics. Collected data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation with SPSS/WIN 23.0. Results: In terms of good death awareness, a significant difference was observed; in according to age (F=3.35, p=.037), payer of treatment costs (F=3.98, p=.021), mobility (F=3.97, p=.021), heard discussion about ADs (t=-3.89, p<.001), and willing to complete ADs (t=2.12, p=.036). As far as attitudes toward ADs, the participants presented significant difference depending on religion (t=2.38, p=.018), average monthly income (F=3.91, p=.022), duration of hospital admission (F=5.33, p=.006), person to discuss ADs (t=-2.76, p=.006). On PCEOL, there was a significant difference, depending on religion (t=-3.59, p<.001) and perceived health status (F=3.93, p=.022). Finally, as for how the variables were related to each other, good death awareness and attitudes toward ADs had a weak positive correlation with PCEOL. Conclusion: To help seniors staying in nursing homes face a good death and enjoy autonomy, there should be educational and support systems that reflect each individual's sociodemographic characteristics so that the seniors can choose what kind of care they want to receive near the end-of-life.

This paper is concerned with investigating the asymptotic behavior of end effects for a generalized heat conduction problem with an added dissipation term defined on a three-dimensional semi-infinite cylinder. With homogeneous Dirichlet conditions on the lateral surface of the cylinder it is shown that solutions either grow exponentially or decay exponentially in the distance from the finite end of the cylinder. In particular, to render decay estimate explicit, we pattern after the analysis of Payne and Song [13, 15]. The continuous dependence effect of perturbing the equations parameters is also investigated.

The term ‘High Speed Machining’has been used for many years to describe end milling with small diameter tools at high rotational speeds, typically 10,000 - 100,000 rpm. The process was applied in the aerospace industry fur the machining of light alloys, notably aluminium. In recent you, however, the mold and die industry has begun to use the technology for the production of components, including those manufactured from hardened tool steels. And the end mill is an important tool in the milling process. A typical examples for the end mill is the milling of pocket and slot in which a lot of material is removed from the workpiece. Therefore the proper selection of cutting parameter fur end milling is one of the important factors affecting the cutting cost. The one of the advantages of HSM is cutting thin-walled part of light alloy like Al(thinkness about 0.1mm). In this paper, firstly, we study characteristics of HSM, and then, we choose the optimal parameters(cutting forces) to cut thin-walled Al part by experiment.

Purpose: The purpose of this study was to understand the nurses' experiences of end of life care of older adults with dementia living in long-term care hospitals and geriatric care facilities. Methods: The participants were nine nurses. Open in-depth interviews were used to collect data from June, 2016 to November, 2016. Colaizzi's phenomenological approach was used to analyze the data. Results: Three categories were identified. The nurses' reported experiences of end of life care of older adults with dementia were 'warm care with living together', 'care for family', and the 'self-reflection and responsibility as a nurse'. There were ten clusters of themes and 24 themes. The participants stated that the end of life care of older adults with dementia were individualized holistic care with dignity, being in older adults with dementia and family, and responsibility as a professional. Nurses reported the need for dementia hospice care. Conclusion: These results could be considered in planning nursing intervention for hospice care. The findings support the need for educational strategies and programs to improve end of life care among older adults with dementia.

Despite improvement in respiratory care, including use of low pressure and high volume cuffed tubes, tracheal stenosis remains a serious complication after a long-term tracheal intubation and tracheostomy. In such patients, tracheal resection and primary anastomosis is still considered ideal therapeutic modality. Between 1989 and 1997, we performed tracheal resections with end-to-end anastomosis on 14 patients with no operative mortality and some morbidity. Tracheal stenosis was caused by tracheostomy in nine patients, by endotracheal intubation in three patients and by thyroid carcinoma in two patients. The length of stenosis was various from 2cm to 4.5cm. All patient underwent segmental tracheal resection and primary anastomosis(14 patients) and additional procedures were cricoid cartilage reconstruction(2 patients), suprahyoid laryngeal release(3patients), carinal release technique(2 patients) and arytenoidectomy(2 patients). We have nine complications: granulona at anastomosis site in four patients, vocal cord palsy in two patients and restenosis, pneumonia, skin necrosis in each of those patients. The granuloma was removed by bronchoscopic forceps(4 patients). Vocal cord palsy was treated by arytenoidectorny(2 patients), restenosis by T-tube insertion, pneumonia by antibiotics and skin necrosis was treated by skin graft. We reviews our expenence of clinical features of tracheal stenosis and surgical treatment by tracheal one-to-end anastomosis with additional procedures to avoid postoperative complications for sucessful results.

A geochemical approach to the long-term safety of waste disposal is discussed in connection with the significance of actinides, which shall deliver the major radioactivity inventory subsequent to the relatively short-term decay of fission products. Every power reactor generates transuranic (TRU) elements: plutonium and minor actinides (Np, Am, Cm), which consist chiefly of long-lived nuclides emitting alpha radiation. The amount of TRU actinides generated in a fuel life period is found to be relatively small (about 1 wt% or less in spent fuel) but their radioactivity persists many hundred thousands years. Geological confinement of waste containing TRU actinides demands, as a result, fundamental knowledge on the geochemical behavior of actinides in the repository environment for a long period of time. Appraisal of the scientific progress in this subject area is the main objective of the present paper. Following the introductory discussion on natural radioactivities, the nuclear fuel cycle is briefly brought up with reference to actinide generation and waste disposal. As the long-term disposal safety concerns inevitably with actinides, the significance of the aquatic actinide chemistry is summarized in two parts: the fundamental properties relevant to their aquatic behavior and the geochemical reactions in nanoscopic scale. The constrained space of writing allows discussion on some examples only, for which topics of the primary concern are selected, e.g. apparent solubility and colloid generation, colloid-facilitated migration, notable speciation of such processes, etc. Discussion is summed up to end with how to make a geochemical approach available for the long-term disposal safety of nuclear waste or for the performance assessment (PA) as known generally.

Purpose: This study aimed to investigate possible ways to expand the services of home-visit nursing through a review of the progress, achievements, and obstacles of home-visit nursing; a pilot project of an integrated home-service; the application of the Omaha System; as well as a case analysis of providing home-visit nursing services. Method: An integrated review was conducted using various source materials, including laws, previous studies, and a case analysis. Results: In case analysis of providing visiting nursing service, rehabilitation nursing, end-of-life nursing, and dementia care showed high nursing needs. It was necessary that the various home visit nursing services in the intervention area of the Omaha System, administrative services, case management, and center operation activities were all included in the payment systems of long-term care insurance. Conclusion: In the future, home visit nursing services of long-term care insurance should be reborn in the form of a center for integrated case management in the community, which would set long-term goals until the time of a client's death and encompass the realm of human rights for health, quality of daily life, and a dignity of life.
