With the increasing demand for improving the quality of life of the people, the need for resident-friendly use and management of rivers is increasing. This study develops an indicator that can measure the performance of the multi-faceted function of the river that the general population can appraise, and in particular, the subjective satisfaction of residents. Based on related prior studies and case analysis, a draft indicator system covering maintenance of river facilities for flood control, water use, environment protection, and water-friendly use functions was established. Through a factor analysis adopting PCA extraction method and VARIMAX rotation method and survey, a performance indicator system consisting of three areas, six detailed areas, and 24 items is drawn. Also, the developed indicators are applied to national and local rivers in Daejeon to suggest implications through comparative analysis.

Energy saving strategy for public housing is given a sizable portion in Land and Housing corporation. From this reason, the consumer's characteristics and energy consciousness of public housing dweller was derived from field survey for compare with sale housing residents characteristics. Utilities fees (e.g. gas and electric) for public housing residents was about 50 percent of sales housing dweller, but real energy consumption was accounting for 70% of sales housing residents in electric consumption. Among the respondents for public housing dweller up to 80 percentile of end-user comment that they have less demanding utilities fees. Given the major energy saving strategies, such as install EMS, make a teaching tool for children, sale housing residents is more proactive approach to participant energy saving strategies than public housing residents.

With mobile computing, wireless sensor network and sensor technologies, ubiquitous computing services are being realized and could satisfy the feasibility of ubiquitous healthcare to everyone. This u-Healthcare service can improve life quality of human since medical service can be provided to anyone, anytime, and anywhere. To confirm the vision of u-Healthcare service, we've implemented a healthcare system for heart disease patient which is composed of two components. Front-end collects various signals such as temperature, blood pressure, SpO2, and electrocardiogram, etc. As a backend, medical information server accumulates sensing data and performs back-end processing. To simply transfer these sensing values to a medical team may be too trivial. So, we've designed a model based on context awareness for more improved medical service which is based on artificial neural network. Through rigid experiments, we could confirm that the proposed system can provide improved medical service.

Background and objectives: One-person households are the fastest growing family type in Korea. They bring social concerns such as weakened social integration, increasing poverty and social isolation. They are not homogeneous but heterogeneous groups depending on their socio-demographic characteristics including generation. This study compared the life satisfaction level as well as factors affecting it among the three one-person household generations Methods: The 13th wave of the Korea Welfare Panel dataset with 1,187 respondents was utilized. For data analysis Chi-square test, analysis of variance and hierarchical regression analysis were employed. Generations are divided into three, namely young adult (20-39), the middle-aged (40-64) and the elderly (65 and over). Result: The life satisfaction level was highest among the young adult one-person household generation, followed by the middle-aged and the elderly generation. The common factors affecting life satisfaction of the three generations were physical as well as mental health, including self-esteem and depression. However, there were more factors different from generation to generation. As for the young adult, age, religion, and smoking were significant. As for the middle aged and the elderly, gender (male) and income were significant. Additionally, age, home-ownership and drinking were significant to the elderly generation. Conclusions: As there are differences as well as similarities among the three generations, policies for one-person households need to be devised considering these findings. For all generations, both physical and mental health policies are needed. For young adult strengthening social relations, providing decent jobs, and promoting anti-smoking policy are major agenda, and for the middle-aged and the elderly, assisting in social capital accumulation (for male), providing stable jobs and diverse leisure activities, and securing income. Additionally, for the elderly, expanding the social security system and housing support are needed.

This study covers the effectiveness of SNS utilization education for the elderly. Participants in the study conducted in-depth interviews with trainees currently participating in education and mentors of the same age who are working as assistive instructors. The study deals with whether SNS utilization education, which is considered difficult, can be a more valid class when an elderly person of the same age becomes a mentor and teaches a class. The results of the study said that it was a fun and rewarding education after using SNS for the elderly, free from fear of difficult devices due to the friendly consideration and empathy of the same age. If a mentor of the same age is used for education on SNS for the elderly, SNS education, which has been considered difficult and burdensome for the elderly, is expected to be activated with more flexible education.

It is important to prevent progression of mild cognitive impairment (MCI) to Alzheimer's disease or other dementia. This study was conducted to investigate cognitive-based intervention and its effectiveness for the older patients with MCI through systematic review. Data search was conducted in September 2020, using the Korea Research Information Service (Riss) and KoreaMed. After selection of literatures according to the predefined inclusion criteria, a total of 12 articles were included. It is revealed that the cognitive-based intervention for the older adults with MCI was found to have a positive effect on the various factors including cognitive function, depression, physical health status, quality of life, and communication. However, it is difficult to draw a definite conclusion due to the various intervention strategies and instruments used. Thus, based on the results of this study, we suggest more studies to verify the effectiveness of such programs.

Objective : The aim of this study was to investigate the prevalence of anxiety symptoms and its association with psychological factors in patients with hypertension. Methods : The Participants included 124 patients with hypertension. Anxiety symptoms were evaluated by the Hospital Anxiety and Depression Scale. Socio-demographics, perceived stress, state-trait anger, life satisfaction, and ego resiliency were assessed. Stepwise multiple regression analyses were carried out to examine the impact of perceived stress, state-trait anger, and life satisfaction on anxiety symptoms. In addition, moderated regression analysis was performed to explore the moderating effect of ego resiliency between perceived stress and anxiety symptoms. Results : A total of 17 subjects (13.7%) were identified as having anxiety symptoms. Higher perceived stress and state-trait anger, and lower life satisfaction were found to be significant correlates of anxiety symptoms. In the final model, higher levels of perceived stress (β=0.378, p<0.001) and trait anger (β=0.320, p<0.001) were related to higher levels of anxiety symptoms, while a higher level of life satisfaction (β=-0.166, p=0.025) was associated with a lower level of anxiety symptoms. Further, ego resiliency buffered the negative effect of perceived stress on anxiety symptoms. Conclusion : This study demonstrated the prevalence of anxiety symptoms and associated psychological factors among patients with hypertension. Our findings suggest that improving life satisfaction and ego-resiliency as well as controlling stress and anger may be important in the management of anxiety symptoms in patients with hypertension.

This study predicts the economic activity level of the elderly in Korea using various machine learning methods. While the previous studies mainly focused on testing the relationship between the economic activity level and the life satisfaction or the social security system, this study aims at the accurate prediction on the economic activity level of the elderly using various machine learning methods and the forecast combination. Dependent variables such as the activity rate, employment rate, etc and independent variables such as the income, average wage, etc compose the dataset in this study. Five different machine learning methods and two forecast combinations are applied to the given dataset. The prediction performances of the machine learning method and the forecast combination varied across the dependent variables and prediction intervals, but it was found that the forecast combination was relatively superior to other methods in terms of the stability of prediction. This study has significance in that it accurately predicted the economic activity level of the elderly and achieved the stability of the prediction, raising practicality from a policy perspective.

This study exploratoryly examines the effect of time poverty experienced by tourists on the quality of tourism due to the recent rapid change in the tourism service system. Due to various reasons, the process of consuming considerable time and energy of the mind along with anxiety, tension, and anxiety caused by the sense of time poverty experienced by tourists occurs. As a result, time poverty comes and the quality of tourism decreases. On the other hand, the factor of trust in the change of the tourism service system is also an important axis for satisfaction, but if a problem occurs in efficiency related to time, satisfaction with the tourism service may decrease. From this point of view, this study conducted a literature review focusing on the fact that time poverty due to changes in the tourism service system reduces the satisfaction of tourists and even affects the quality of tourism. Through this, various implications were provided for the government's policy to support workers' leave.
