Korea is facing one of the fastest aging population problems in the world due to the extension of life expectancy and low birth rates due to economic development and the development of health care. It has become difficult to take care of elderly people in need of long-term care at home, and social problems such as dementia and the increase in stroke cases are serious problems. The government is enacting and implementing the Long-Term Care Insurance Act for the purpose of improving the quality of life for senior citizens subject to long-term care and alleviating the burden of family support in order to solve such social structure and problems for senior citizens. However, as a result of the implementation of the long-term care insurance system for the elderly, the privatization of the facilities and the disorder are causing widespread requests for public accountability of the services and the enhancement of the quality of the facilities. In addition, various arrangements are needed for the production of low-wage medical care workers, tasks for quality improvement, problems regarding financing methods, and so on. In order to maintain and develop the long-term care insurance system for the elderly, the government will consider seeking ways to improve the legal and institutional aspects according to changes in the social environment of the age, as well as seeking mental and psychological measures for the stabilization of old life as well as physical health.

Objectives: The purpose of the study is to investigate the awareness toward use and service contents of long term care for the elderly. Methods: A self-reported questionnaire was completed by 296 adults from August 13 to October 20, 2014. The questionnaire consisted of general characteristics of the subjects, awareness toward long term care insurance for the elderly, awareness toward long term oral health care services, use of long term care service and use intention for the long term care insurance. Data were analyzed by SPSS 18.0 program. Results: Those who were aware of the long term care insurance accounted for 55.4 percent. Approximately 50 percent of the respondents recognized long term care service items, home visit care, home visit bathing, and home visit nursing. Most of the respondents had information of long term care services by way of mass media and direct contact. Only 13.4 percent of the respondents were aware of the oral health service in the long term care insurance. The subjects were aware of denture cleaning, oral cleaning and oral health education out of oral health service in order; and oral health services that needed to be offered were denture cleaning, oral health education and professional toothbrushing. They reported that dental hygienists were the most important manpower that offered the efficient oral health care services. They answered that professional manpower and financial support are required for oral health services. The positive thinking to long term care insurance accounted for 89.2 percent and 91.3 percent had use intention for oral health services. Conclusions: Many elderly people have mastication or dysphagic problems due to systemic diseases. Therefore, it is necessary to announce the long term care insurance and long term care services for the elderly people.

Government came to enforce long-term care insurance system in preparation for the rapid aging society. Whether this system is successful or not depends on the professionalism of long-term care-givers who are professional population in charge of care service. Currently in the early stage of enforcement, such problems as a race cutting fee resulted from numerical increase of educational facilities, insolvent operation, degradation of education level resulted from unprofessional instructor, are pointed out. As a mean of manpower-training on long-term care insurance system, this study is to research public-private-university network model of the Academy of Continuing Education attached to Ko Sin University which is the case of Yong Do Gu Busan city. Networking between the vision and development strategy of Yong Do Gu on continuing education city, education system on community manpower-training supported by Ko Sin University, and service field of welfare for the elderly can not only contribute to the professionalism of long-term care-givers but also play an ideal role in manpower-utilization and arrangement of community. Through this networking, high quality of education level and circumstance, using the existing infra, manpower-training and utilization for continuing education of Yong Do Gu can be accomplished. Additionally, the connection with facilities related with welfare for the elderly can contribute to professionalism and accountability of manpower-networking.

Korean government is preparing the long-term care financing and delivery system in order to cope with rapid population aging. The system should be designed to provide demented patients with an appropriate services that the patients want to take, and considered to be necessary for them. In this regard, this study aims to analyse empirically a relationship between the types of long-term care services that demented patients wanted to take and they actually received during 2004. The caregivers of 609 dementia patients, who were randomly selected in a manner of proportional allocation from a nationwide claim database of the Korean National Health Insurance Corporation, were interviewed in September, 2005. Independent variables include socio-demographic characteristics, Activities of Daily Living(ADL) and Instrumental Activities of Daily Living(IADL). To explore the correspondence of the types of long-term care services that demented patients wanted to take and that they actually received, and its affecting factors, we conducted chi-square test and logistic regression analysis. Main findings are as follows. First, while only 20% of study subjects wanted home services as a long-term care services, those who wanted to use the long-term care facilities and general hospital were 37%, 43% respectively. Second, the correspondence rate was just 38% on average, and extremely low in the demented patients who wanted to use long-term care facilities. Third, the demented patients who resided in urban areas and received relatively high level of education showed high correspondence rate. Fourth, the high ADL score was closely related to low correspondence rate.

Chloride penetration is among the main causes of corrosion initiation in reinforced concrete (RC) structures producing premature degradations. Weather and exposure conditions directly affect chloride ingress mechanisms and therefore the operational service life and safety of RC structures. Consequently, comprehensive chloride ingress models are useful tools to estimate corrosion initiation risks and minimize maintenance costs for RC structures placed under chloride-contaminated environments. This paper first presents a coupled thermo-hydro-chemical model for predicting chloride penetration into concrete that accounts for realistic weather conditions. This complete numerical model takes into account multiple factors affecting chloride ingress such as diffusion, convection, chloride binding, ionic interaction, and concrete aging. Since the complete model could be computationally expensive for long-term assessment, this study also proposes model simplifications in order to reduce the computational cost. Long-term chloride assessments of complete and reduced models are compared for three locations in France (Brest, Strasbourg and Nice) characterized by different weather and exposure conditions (tidal zone, de-icing salts and salt spray). The comparative study indicates that the reduced model is computationally efficient and accurate for long-term chloride ingress modeling in comparison to the complete one. Given that long-term assessment requires larger climate databases, this research also studies how climate models may affect chloride ingress assessment. The results indicate that the selection of climate models as well as the considered training periods introduce significant errors for mid- and long- term chloride ingress assessment.

Background: This study aimed to identify patterns of elderly patients who transferred from long-term care hospitals to emergency rooms and provide the evidence of emergency medical systems to prepare for a super-aged society. Methods: The data source was the National Emergency Department Information System database from January 2014 to December 2019 in Korea. We performed a cross-sectional study among elderly patients (≥65 years) who transferred from a long-term care hospital to an emergency room. Trend analysis was conducted by year. Results: We identified 225,765 elderly patients who were transferred from long-term care hospitals to emergency rooms between January 1, 2014 and December 31, 2019. The proportion of the study population and their mean age were recently increased (p<0.001, respectively). The proportion of elderly patients being re-transferred (p=0.049) and the patients re-transferred to long-term care hospitals is significantly increased (p=0.005). Conclusion: The establishment of efficient emergency medical services for an aging society is important. It is necessary to develop a healthcare network with the government, long-term care hospitals, and medical institutions in the community suitable for preventing disease deterioration.

The use of fiber-reinforced polymer (FRP) reinforcing bars in concrete structures has been increased as an alternative of steel reinforcement which has shown greater vulnerability to corrosion problem. However, the long-term performance of concrete members with FRP reinforcement is still questioned in comparison to the used of steel reinforcement. This study presents the results of an experimental study on the long-term behaviors of GFRP (glass fiber reinforced polymer) bar reinforced concrete beams after exposed to accelerated aging in an environmental chamber with temperature of $46^{\circ}C$ ($115^{\circ}F$) and 80% of relative humidity up to 300 days. The objectives of this research was to compare strength degradation and change of ductility between GFRP reinforced concrete beams and steel reinforcement beams after accelerated aging. Two types (wrapped and sand-coated surface) of GFRP bars and steel were reinforced. in concrete beams. Test results show that the failure modes of GFRP bar reinforced concrete beams are very similar with traditional RC beams, and the change of load-carrying capacity of steel reinforcing concrete beam is greater than that of GFRP bar reinforcing concrete beam under the accelerated aging. Test result also shows that the use of GFRP reinforcing in concrete could be introduced more brittle failure than that of steel reinforcing for practical application. The deformability factor up to compression failures indicates no significant variation before and after exposure of accelerated aging.

Polymeric composite insulators have been in use for outdoor insulation. However, our knowledge about their long-term performance in an outdoor environment is still very limited. Especially, these insulators are subjected to the environmental stress such as ultraviolet radiation, electrical stress, mechanical load, etc.. Hence, in this paper, we simulated the factors having influence on aging of polymer insulators using the combined aging test chamber. In order to evaluate an aging characteristics with time, we measured leakage current on these insulators to make out the degree of aging.

In order to improve the reliability of XLPE cables, it is necessary to find the useful diagnostic parameter according to long term aging. This paper described the change of partial discharge(PD) phase Properties of XLPE cable insulation with branch type electrical tree degradation. for long term aging. To understand the PD Properties with $\phi$ -q-n distributed shape of XLPE insulation, specimens were prepared by 22.9㎸ distribution cable and made in a type of block(16${\times}$16${\times}$3[mm]). Ogura needles having tip radius of l0${\mu}{\textrm}{m}$ were inserted into each block pieces. The measuring system was consisted of PD detector, digitizer for digital conversion, VXI system for signal processing. The PD properties of the specimens were measured from initiation of tree to breakdown and their characteristics were analyzed. We analyzed the relationship between electrical properties(PD Quantity, PD initiation angle, PD extinction angle, PD occurrence angle : (PD extinction angle - PD initiation angle)) and the normalized aging rate. We found PD parameter, PD initiation angle and occurrence angle, which are a useful diagnostic parameter in estimating the branch type electrical tree for XLPE insulation condition.
