This study was to investigate basic level of physical activity test that reflects activity of daily living(ADL) for institutionalized elderly women. The subjects were 105 elderly women over than 65 years living in long-term care facilities located in Daejeon and Chungnam. The measured eight items related to ADL were tested and the data was analyzed by descriptive statistics, one-way ANOVA, factors analysis and correlation. The results were statistically significant differences. Among eight test items, two factors(muscle strength and mobility) were extracted by principal component factor analysis(PCA). The two factors are appropriate domains for assessment of basic physical activity of institutionalized elderly women. By using Pearson's correlation, between two factors and age, the first principal component scores were significantly decreased with age increasing. Degradation of ADL must be prevented for institutionalized elderly women through maintain muscle strength and mobility.

As apartment buildings defect lawsuits become socioeconomic problems, an objective basis system for the term of warranty liability of reinforced concrete constructions is urgent. This study was carried out as a basic study for developing a basis system for the term of warranty liability. To do this, defect data actual collected in apartment complexes were collected and analyzed. As the result of checking the cumulative rate of defect occurrence in reinforced concrete construction by year, the point of time of reaching the 90% level was the 5th years, which was similar with the provision of the Apartment Building Management Act. However, the current Supreme Court precedent has decided that the term of warranty liability for the main structural parts in reinforced concrete construction shall be 10 years and the dispute is expected to continue in the future in the defect lawsuit.

As same time of starting on the Korean Long-term Care Insurance System, the government developed a program to train new qualification of long-term care workers. The number of enrolled long-term care workers are 950,000 persons in 2010. Mostly they are working in home based care work places such as home visit care centers and home visit bathing centers covered insurance. The purpose of this study is to understand the difference of task performance requirement according to long-term care workers' responsibilities which divided into home visiting care and home visiting bathing. The comparison analysis was conducted to task performance requirement in basic management, safety management, administration management, practical services. Key result was found that task performance requirement of long-term care workers whose responsibilities are home visiting care were more higher than the home visiting bathing. Finally, To improve quality of home visiting care and home visiting bathing, it is necessary to provide the fields based continuing education and reflect new reimburse system.

Objectives: In order to cope with the quality and the substantiality issues in long-term care for the elderly, we should have a wider view of long-term system components based on the understanding of health care organizations, management services, support for care providers and beneficiaries, education of the workforce, and management of finance and resources. Methods: For resolving the issues raised and offering guidance in the area of long-term care, we reviewed 20 reports and documents of the government and government-related institutions using the Internet home pages of the Australian government and the related organizations in the health care sector. These organizations are undergoing a huge system reform to implement consumer-directed care since 2015, in the areas of service, resources, finances, organization, and management. Results and conclusions: The study outcomes can have some implications for the long-term care system in Korea based on the differences in the service components. The results can provide basic information for improving the long-term care service, and can have several other implications for long-term care in Korea.

We would like to develop a short-term model to predict the time-related concentration of ozone whose reaction mechanism is complex. The paper targets Seoul where an ozone alert system has recently been employed. In order to develop a short-term prediction model for ozone, we suggested the Ozone Peak Indicator(OPI), an equivalent of the potential daily maximum ozone concentration, with precursors being the only limiting factor, and we calculated the Ozone Peak Indicarot as OPI={$rac{(O_3)_{max}cdot(H_{eH})_{max}(Rad)_{max}$ to preclude the influence of mixing height and solar radiation on the daily maximum ozone concentration. The OPI on the day of the prediction is to be calcultated by using the relation between OPI and the initial value of precursors. The basic prediction formula for time-related ozone concentration was established as $O_3(1)={(OPI)cdot Rad(t-2)H_{eH}}$, using the OPI, solar radiation two hours before prediction and mixing height. We developed, along with the basic formula for predicting photochemical oxidants, "SEOM"(Seoul Empirical Oxidants Model), a Fortran program that helps predict solar radiation and mixing height needed in the prediction of ozone pollution. When this model was applied to Seoul and an analysis of the correlation between the observed and the predicted ozone concentrations was made through SEOM, there appeared a very high correlation, with a coefficient of 0.815. SEOM can be described as a short-term prediction model for ozone concentration in large cities that takes into account the initial values of precursors, and changes in solar radiation and mixing height. SEOM can reflect the local characteristics of a particular and region can yield relatively good prediction results by a simple data input process.t process.

The aim of this research was to analyze the differences for the oral health status of the elderly people living in the long-term care facilities and the non-resident elderly. The study was conducted on 469 elderly people of the same age, gender and basic living conditions. Elderly residing in long-term care facilities had higher dental caries prevalence(p=0.019), DT(p=0.001), and MT(p=0.047) than non-resident elderly, and had lower FT(p<0.001) than non-resident elderly. The elderly living in facilities were 1.93 times more likely to be caries than non-residents, and 0.73 times more likely to have a filled tooth. The probability of denture use was 0.15 times for the maxillary and 0.13 times for the mandibular. The probability of denture needs was 5.61 times for the maxillary and 5.65 times for the mandibular. All of these results showed significant differences. As a result of this, it can be used as basic data for establishing oral health policy for oral health promotion of the elderly living in Long-term care facilities.

Cases of lawsuit and conflict are increasing because of defects in apartments in use after the completion of construction. Further, with changes in the consciousness of residents and in the social environment, many residents are showing interest in defect-related lawsuits. However, the term of warranty liability defined in the current law is not practically appropriate, and the verification of the determination of the term of warranty liability is insufficient. Against this background, this research aims to evaluate the appropriateness of defect repair periods by examining the actual defect condition of the finishing work among the various defects related to apartments. Collected performance data are analyzed by statistical techniques by considering the defect occurrence rate per construction type and the construction year of the finishing work in apartment construction. The analysis results will be used as basic data for evaluating the appropriateness of the standards for the term finishing works warranty liability.

The exchange rate is considered a tool improving the volume of exports and reducing imports. This paper aims to determine the impact of the exchange rate on exports and imports between Vietnam and the United States in the context of the trade war. The research uses Autoregressive Distributed Lag (ARDL) and Nonlinear Autoregressive Distributed Lag (NARDL) Model in the time-series data from 2010:1 to 2020:9. The ARDL's results support that real exchange rate impact on export and import volumes, but less than the trade war. The trade war helps trade balance increase 0.35%, while the exchange rate increases trade balance 0.191% when the Vietnamese currency devalues 1% in the long run. In the short term, the real exchange rate makes the trade balance decrease. Therefore, the J curve exists between Vietnam and the U.S. The NARDL expresses that the exchange rate is asymmetric both in the short term and the long term. The findings of this study point to two important elements. Firstly, the exchange rate plays a minor role in exports and imports. Secondly, trade war plays a vital role in increasing exports and imports volume between two countries, and the J curve exists between the two countries.

The thermal behavior of an arrayed-waveguide grating made of a silica/polymer hybrid waveguide was examined. We experimentally confirmed that the hybrid waveguide is effective to decrease the temperature and polarization dependence of the center wavelength owing to the negative thermo-optic coefficient of the refractive index and extremely low baking temperature of the polymer cladding. However, the detachment of the polymer cladding from the silica core, which took place either during a repeated heat cycle test or during long-term storage in atmosphere, was a serious problem for practical use.

Purpose: This study was to analyze the factors that affect the service relationship of long term care workers for the elderly and to provide basic resource for the successful connection of long term care services. Methods: 259 subjects who were engaged in long term care units completed a self-administered questionnaire that measured the extent of service linkage among one another. The Cronbach's ${\alpha}$ score determined the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Multiple regression analysis was conducted to investigate the influence of the known factors on the service linkage. Results: Acceptance and participation negatively influenced on the service linkage. Reliance, comprehension, recognition on service, and frequent contact with others positively activated the service linkage of long term care workers. Conclusion: The establishments of systemic training courses providing education that emphasizes reliability and recognizes other services, including work environment to contact easily are needed to improve the service-linkage of long-term care workers for the elderly.
