This study examined the longitudinal changes of self-perceptions of own aging among middle-aged and elderly adults, using the latent growth modeling with the three waves of the "Aging and the Quality of Life of the Elderly in Korea", which sampled adults aged over 45 living in Seoul and Chuncheon. The dependent variable is attitudes toward own aging, the sub-scale of the Philadelphia Geriatric Center Morale Scale developed by Lawton (1975). The results showed that the research participants' attitudes of their own aging deteriorated over time. In addition, the lower initial status of the research participants' attitudes of their own aging was associated with being older, being non-married, living in rural areas, attaining the lower level of education, having the fewer social activities, reporting the worse subjective economic status, and reporting the worse subjective health status. The slope of the research participants' attitudes of their own aging differed by the residence areas, educational attainments, subjective economic status and subjective health status. In particular, the difference of the initial status by educational attainments grew over time. Social welfare policy and practice implications are discussed for middle-aged and elderly adults to improve attitudes toward their own aging.

PURPOSE. Prevention of xerostomia and stress is important to prolong healthy life expectancy and improve the quality of life. We aimed to investigate the effects of tongue rotation exercise for increasing salivary secretions and stabilizing salivary stress hormone levels. MATERIALS AND METHODS. Twenty four participants without subjective oral dryness were enrolled. The exercises comprised tongue rotation exercise and empty chewing. The salivary stress hormone level was measured using a Salivary Amylase Monitor. Unstimulated whole saliva volume and salivary amylase activity were measured before tongue rotation exercise or empty chewing and subsequently 5, 10, and 15 minutes after these exercises. Differences in the rates of change of unstimulated whole saliva volume and salivary amylase activity were analyzed by repeated measure analysis of variance. RESULTS. Statistically significant differences among the rates of change were not observed after empty chewing for unstimulated whole saliva volume and salivary amylase activity at the four measurement times. However, the rate of change of unstimulated whole saliva volume and salivary amylase activity were statistically significantly different among the four time points: before the tongue rotation exercise and 5, 10, and 15 minutes post-exercise (P<.05 and P<.01, respectively). CONCLUSION. Tongue rotation is effective in increasing saliva secretion, reducing stress, improving oral function, and extending healthy life expectancy.

Purpose. The purpose of this study was to survey the prevalence rate of cognitive impairments and to identify the factors influencing cognitive impairment in the elderly in rural communities of Jeju Province. Methods. 590 elderly in 6 rural communities of Jeju Province were interviewed, using a questionnaire consisting of sociodemographic characteristics, health behavior, quality of life, and MMSE-K Results. Prevalence of cognitive impairment was 33.1 % (39.1 % of females, 16.76% of males). Prevalence of dementia was 12.4% (16.3% of females, 2.87% of males). Factors related to cognitive impairment were age, sex, education, standard of living, employment status, and subjective health state. Conclusions. In community health care for the elderly, factors relating to cognitive impairment have to be considered. When planning community health care, priority should be given to the elderly; who need care but live alone; who lack social support; who have a low standard of living; who experience discomfort in the activities of daily living; who believe they are not in a good state of health; or whose life satisfaction is low.

Recently, the importance and effectiveness of neighborhood forests have been increasing in relation to the quality of life of urban residents. However, there are very few domestic studies that analyzed the correlation between visit characteristics and life satisfaction. Therefore, the study aims to understand how people use the forest for recreation and determine how visit characteristics in neighborhood forests affect individual life satisfaction(ILS). A nationwide survey (N=2,624) was conducted on visit frequency, proximity to forest, means of transportation, forest activities, and life satisfaction. To measure ILS, we used the three factors (personal, relative, collective) of COMOSWB (Concise Measure of Subjective Well-being) developed by Seo et al.(2011). The analysis shows that people usually visit the forest located within the distance of 10-30 minutes from their homes 1-2 times a month on foot for hiking/walking (forest bathing). In particular, the older visitors(over 60s) tend to visit the forest more often than the younger ones (20s). Furthermore, more frequent visitors are more likely to live near the forest. As a result of analyzing the correlation between visit characteristics and ILS by controlling demographic variables, it was found that 'visit frequency' had a positive effect on ILS, and 'proximity to the forest' did not have a statistically significant effect on ILS. In other words, residents who live near the forests are more likely to be satisfied with their lives by visiting frequently. The significance of the study is that it statistically determined that visit frequency is a key factor for ILS. Future studies should take into account the various qualitative factors of forest visit such as vegetation, quantity and types of forest, which will contribute to setting the direction for urban forest development and management.

As the interest in the positive quality of life is increasing throughout the world, the number of people who are suffering from negative sentiments, such as depression, anxiety, or stress, is increasing, as well. Especially, the adolescence period is the period of transition from childhood to adulthood and accompanies significant changes in terms of the body and mind alike. The purpose of this study is to examine the negative sentiment of the juveniles, caused by the stress they experience in their social and personal domains and the distress tolerance that can protect the inner feelings of them at the same time, to understand how they are related to the subjective well-being of the juveniles. For this study, the researcher employed the data from 362 high school students from the high schools located in Seoul and Gyeonggi area, which were analyzed using the statistics suites SPSS 22.0 and AMOS 22.0. According to the findings of this study, first, the depression and anxiety of the adolescent population showed a significant relationship for each variable with regard to the distress tolerance and the subjective well-being. Especially, the negative correlation with the subjective well-being was highly significant. Second, the depression and anxiety of the juveniles turned out to influence the distress tolerance and subjective well-being of them in a negative manner. In both distress tolerance and subjective well-being, the influence of anxiety was higher than that of depression. Third, in the relationship between depression, anxiety, and subjective well-being, the distress tolerance turned out to have a mediating effect. Such results of this study provided the basic data for suggesting the strategies to promote the perceived psychological well-being and help the juveniles who are under stress.

This study aims to examine the impact of decline in quality of life on perceived fairness and support for real estate deregulation. The rise of dissatisfaction due to the deterioration in the quality of life can increase the blame for the unfairness of the external social system, which may boost support for government-led market regulation to correct such unfairness. This impact of perceived fairness on quality of life furthermore could be more pronounced when the prospect of upward social mobility is pessimistic. That is, when people expect that they are more likely to be the socially underprivileged who are to be more vulnerable to the fallout from the unfair operation of social system, the possibility of associating the deterioration in quality of life and the decrease in perceived fairness could be more pronounced. To test these predictions, this study used the dataset comprising a total of 6,300 survey responses and substantiated such predictions. Overall, these results not only offer an opportunity to take a more detailed look at the underlying causes of the recent rise of the issue of fairness, but also contribute to broadening the understanding of how individual support for government's deregulation of real estate varies as a function of perceived fairness and prospect of upward social mobility.

Today, the use of a vacuum cleaner gave us the higher quality of life than past time, but sometimes made us w1comfortable in the house because of the specific noise that is annoying. So we need to study how sound absorbtion materials affect sound power level and sound quality with sound metrics. In this paper, we will measure and calculate sound power level for vacuum cleaner and analyze characteristics of the noise for 10 Signals according to materials positioned in vacuum cleaner. The multiple regression analysis can estimate the nonlinear characteristics of relation between subjective evaluation and sound metrics. So we will develop sound quality index for vacuum sound.

The purpose of this study was to examine the changes of emotion experiences in old age and confirm the effects of emotional characteristics on the subjective well-being in old age by the longitudinal study. This longitudinal study started from 2003 and every two year we performed panel study. We analysed the data from old participants who participated tree-times(2003, 2005, 2007)and over 65 year-old. Finally, 844 old participants(male, 340; female, 504)' data were analysed. The elderly experienced more positive emotions than negatives and these results represented affective optimization. We performed mixed ANOVA method and confirmed significant change of emotion experiences during 6 years. Positive emotion experiences and negative emotion experiences were decreased as they get older. We also examined the effects of emotional experiences on the subjective well-being. In results, emotion experiences were more effective than the demographic variables for maintaining subjective well-being in old age. Decreasing negative emotion experiences and increasing positive emotion experiences can keep happy life up in old age. The importance of the quality of emotional life in old age and the necessity of longitudinal study of aging were discussed.

In modern society, people live in an environment with artificial or natural noise. Especially, the sound that corresponds to the artificial noise makes the noise itself and affects each other because many people live and work in the city. Sounds are generated by the activities and causes of various people, such as construction sites, aircraft, production machinery, or road traffic. These sounds are essential elements in human life and are recognized and judged by human auditory organs. Noise is a sound that you do not want to hear by subjective evaluation, and it is a loud sound that gives hearing damage or a sound that causes physical and mental harm. In this study, we introduce the method of stimulating the human hearing by finger vibration and explain the advantages of the proposed method in various kinds of a noise environment. And how to improve the sound quality to improve efficiency. In this paper, we propose a method to prevent the loss of hearing loss and the transmission of sound information based on proper signal to noise ratio when using portable IT equipment in various noise environments.

Social networking service (SNS), which is based on the "six degree separation" theory, has gained its popularity in recent years. SNS creates a new way for maintaining relationship and sharing information over the virtual space. As a major branch, campus SNS provides a new platform for student to study as well as build and maintain inter-personal relationships. The highly realness of personal information and relatively strong group cohesion of campus SNS has turned it into an inevitable tool in students' daily life. The rapid growth of SNS in campus is creating huge academic and commercial benefits. However, little comprehensive research reveals what are determinant factors in driving students' intention to participate in campus SNS. In this paper, we conceptualize the participation of campus SNS as a social behavior and evaluate the impact made by social factors such as subjective norms and identity, as well as the impact of perceived reality and playfulness through an extended technology acceptance model.
