This paper investigates how social trust and disability identity influence subjective health, focusing on the moderating effect of social-economic status of people with disabilities. We used surveys used for the development of the social exclusion scale of people with disabilities. As a result, social trust and disability identity influence subjective health. Namely, those who have more social trust and high disability identity experience subjective good health than other people with disabilities do. Second, the relationship between disability identity and subjective health was moderated by social-economic status of people with disabilities. Namely, the relationship between disability identity and subjective health is bigger as the level of social-economic status is higher. However, the relationship between social trust and self-rated health was not moderated by social-economic status of people with disabilities. Based on these findings, we suggest policy and practice ways to promote the subjective health status of people with disabilities.

The purpose of this study was to identify the influence of grateful disposition and subjective well-being on stress coping of college students in the convergence society. The participants were 336 college students, data were analyzed using t-test, Pearson Correlation, Multiple regression. It was found that: nursing students showed higher score at grateful disposition, life satisfaction, and positive stress coping than non-nursing students. 2nd grade students's grateful disposition, and negative stress coping score were significantly higher than non-nursing students. Significant correlation were found among grateful disposition and subjective well-being on stress coping. The factors influencing stress coping were grateful disposition, and positive affect. Therefore some effective way to enhance of subjective well-being and grateful disposition through various educational curriculum and extra-curricular activities are needed.

Research on subjective well-being (SWB) has flourished in recent years. As SWB determines cognitive and motivational processes, including social comparison and cognitive dissonance, it determines how consumers make decisions, including the comparison and evaluation of alternatives. Considering that the comparison and evaluation of alternatives is related to social comparison and cognitive dissonance, the influence of SWB on the comparison and evaluation of alternatives needs to be investigated. This research aims to examine the effect of SWB on the comparison and evaluation of alternatives, especially when people acquire additional information about their chosen or non-chosen alternatives, leading to a change of absolute/relative value of alternatives. The reasonable price of an alternative as evaluated by individuals is used as a measure reflecting the perceived value of an alternative. Putting all of this together, the current study intended to investigate the influence of absolute and relative value on the reasonable price of an alternative depending on SWB. Participants were randomly assigned to one of two experiment groups (deterioration of non-chosen alternative vs. improvement of non-chosen alternative). After reading consumer report ratings of alternatives shown on monitor screens, participants chose one of the alternatives, followed by the change of the consumer report ratings (deterioration of non-chosen alternative vs. improvement of non-chosen alternative). Participants evaluated the reasonable price of their chosen alternative based on the provided price of the non-chosen alternative. Two weeks after the experiment, they were asked to answer survey questionnaire on SWB measures. A regression was performed on the reasonable price with experiment groups, mean-centered SWB, and their interaction. There was a significant simple effect of groups and SWB. More importantly, these effects were qualified by the predicted interaction of groups and SWB. To interpret this interaction further, simple slope tests were performed on the price when SWB was centered at one standard deviation above (i.e., happy people) and below (i.e., unhappy people) the mean. As predicted, happy people rated the reasonable price of the chosen alternative higher in the improvement of non-chosen alternative group than in the deterioration of non-chosen alternative group. Conversely, unhappy people showed no price difference between groups. These results show that happy people pay attention to the absolute value of the alternative, whereas unhappy people give more weight to the relative value as well as to the absolute value of a chosen alternative, indicating that unhappy people are more sensitive to the negative information of a non-chosen alternative compared to happy people. The present research expanded the existing research stream on SWB by showing the influence of SWB on the consumers' evaluation of alternatives. Furthermore, this study adds to previous research on SWB and social comparison by suggesting that unhappy people tend to be more sensitive to negative social comparison information of alternatives even when a target of social comparison is not explicitly present. Moreover, these results yield some managerial implications on how to provide product information based on SWB in order to make products more attractive among the alternatives available to consumers.

The purpose of this study is to examine that basic pension entitlement affects the subjective well-being(SWB) of the elderly. For controlling unobserved heterogeneity, we used fixed effects model for longitudinal data. The data used for this study is KLoSA from 2006 to 2016. The research results are as follows. SWB of non-basic pensioners was higher than for basic pension beneficiaries. Second, when the demographic variables were controlled, SWB of the basic pension recipients was higher then that of non-beneficiaries. Third, the factors affecting SWB were economic satisfaction, marital status, family financial support, employment status, subjective health status, daily life restrictions, gender, and age. Fourth, the effect of basic pension on SWB was positive at the lowest income quartile. The results of this study shows that the basic pension system has a positive effect on the SWB of elderly despite the low benefit level. Therefore, it is necessary to expand the basic pension system to solve poverty problems and improve the quality of life for the aged. Also, various aspects of social support for the low-income vulnerable elderly are needed. Lastly, It was suggested that the benefit level of the basic pension should be raised to have a substantial effect on the low-income class, which is a key policy subject.

음질 평가에는 주관적 음질 평가법과 객관적 음질 평가법이 있는데, 주관적 음질 평가법은 사람이 직접 듣고 평가하므로 실제 체감 음질을 나타낸다. 그러나 많은 사람들에 의하여 직접 평가되므로 비용과 시간이 많이 소모되는 단점이 있다. 객관적 음질 평가법은 수학적인 계산에 의하여 원음과 왜곡음의 유사성을 비교하는 것으로 빠르고 비용이 적게 되나 실제 체감 음질과는 거리과 있다. 본 논문에서는 객관적 음질 평가 척도로 BCF(Bark Coherence Function)을 제안한다. BCF는 심리 음향 영역에서 코히어런스 함수를 정의한 것으로 기존의 객관적 음질 평가법에 비하여 주관적 음질과 상관관계가 높고 계산량이 적다. CDMA 이동 전화 시스템의 음성 데이터와 회기분석 결과, BCF가 ITU-T 표준안의 PSQM(Perceptual Speech Quality Measure)와 MNB(Measuring Normalizing Block)에 비하여 높은 상관관계를 갖음을 입증하였다.

In H.264 as the newest video standard, 9 modes are used in order to predict the signal values of a block composed with several pixels by intra prediction. From these process, H.264 can bring high compression ratio in the encoded signal but the use of total 9 modes can give the inefficiency of the increase of the complexity induced by the amount of operation processing or the number of searching which is applied to compare adjacent pixels. This paper proposes a simplification method of prediction mode for the intra-picture coding by considering subjective interest region. There are certain region being interested within a picture of the video sequence. This region requires better subjective picture quality than the other regions. The proposed method increases the simplification of prediction mode by providing just essential modes of total 9 modes for less interest regions compared with the interest region. It is possible to get the additional 11%$\sim$15% simplification of the prediction mode by the proposed method, compared with the conventional method which simplifies the prediction mode for all of the picture by using the prediction characteristics only.

This study is to investigate the influence of leisure experience type and self-efficacy, on subjective well-being in ski resort. The study is to examine the moderating role of leasure experience type (ski related experience and non ski related experience) between self-efficacy and subjective well-being. Further, the relationship between subjective well-being and recommendation intention was investigated. As a result, self-efficacy significantly influenced on subjective well-being (satisfaction of leisure, positive affect). Respondents who are high self-efficacy group have higher subjective well-being (satisfaction of leisure, positive affect) than one who are low self-efficacy group in the ski related leasure experience scenarios. In the non ski related leasure experience scenarios, however, respondents who are low self-efficacy group have higher subjective well-being (satisfaction of leisure, positive affect). Besides, subjective well-being (satisfaction of leisure, positive affect) plays a mediating role between self-efficacy and recommendation intention.

This study intends to verify the poverty characteristics of the rural elderly households so as to provide more specific data for the intervention of social welfare in the improvement of quality of life of the rural elderly. According to my study of the absolute poverty ratio, the poverty gap, the relative poverty ratio, the subjective poverty ratio, the subjective economic level and the life satisfaction level of the rural elderly households in comparison with those of the other groups, the conclusion is as follows: First, the total living cost of the rural elderly households is rather low with the food cost taking about 30% of the total living cost. Second, in terms of the poverty ratio based on socio-demographic characteristics, higher poverty ratio show among women, older people and households of fewer members. Third, 82.2% of the rural elderly households living with an income below the minimum living cost is found around the poverty line. Fourth, the rural elderly households show a comparatively higher poverty ratio than the other groups in the absolute and relative poverty, but lower economic strain than other groups in the subjective poverty ratio and life satisfaction level. In short, the rural elderly households' poverty level is generally high and therefore need ways of active economic supports, while a political approach to the subjective needs of the regional and intergenerational groups is also required.

This study examines the effects of social network support types on the subjective satisfaction of life for elderly people focused on the impact of voluntary and present oriented social network type represented by hobby club vs. non voluntary and past oriented social network type for example alumni association in Korean society respectively. According to the advanced studies figured out by preceding researchers, most of social networks had a good and positive effects on the elderly people's subjective satisfaction of life. However, this study tried to classify the social networks by type such as starting time to make relationship among members and voluntary or non voluntary for participation to the networks. As a result of this study, voluntary and present oriented social network represented by hobby club has a very positive relationship with Korean elderly people's subjective satisfaction of life while non voluntary and past oriented social network as alumni association has no relationship with elderly people's subjective satisfaction of life. Therefore, government policies and budget should be concentrated on encouraging or supporting voluntary and present oriented social networks such as hobby club, voluntary agency etc. rather than non voluntary and past oriented social networks so as to maximize the effect for increasing Korean elderly people's subjective satisfaction of life.

The purpose of this research is to analyzed the Korean adolescents' weight control behaviors by BMI(Body Mass Index) and body shape perception. The data of this study abtained 73,238 adolescents, aged 12-18years from the '2010 6th Korea Youth Risk Behavior web-based Survey. The data were analyzed by frequency, percentile, chi-square test, Binominal Logistic Regression analysis. The results of this research were as following. First, the answer to question about adolescents' body shape perception is high in "normal" and "a little fat", but the result of BMI show that the most of them are in "underweight". Second, the female students tends to perceive themselves obese than male students do. Third, the female student try to lose weight but male student try to gain weight. Also the higher BMI is, the more the student have tendency to try to lose their weight. In conclusion, BSP leds directly weight control behavior, so in order to reduce unnecessary weight loss or improper methods weight control behavior. It is important to educate the students to have a sound perception about body shape.
