This study was conducted to empirically analyze the effect of life behavior and socio-environmental satisfaction on life satisfaction of the elderly with or without hearing loss. To this end, 3,071 elderly people of 「the Survey on the Actual Condition of the Elderly」 in 2020 were set as the subjects. After controlling for their demographic variables, the multiple regression model showed that the elderly with hearing loss had different factors of life behavior and socio-environment satisfaction that affected their life satisfaction compared to those without. As a result, the sub-factors of life behavior in the elderly with hearing loss, such as economic activities, social group activities, the use of the center, and the sub-factors of social environment satisfaction, such as family satisfaction and environmental satisfaction, had a positive (+) effect on life satisfaction. Especially, the elderly with hearing loss had more limitations in both the area of living behavior and the area of social environment satisfaction than the elderly without hearing loss. Therefore, in order to improve the life satisfaction of the elderly with hearing loss, it is suggested that the government and local governments should simultaneously supplement welfare policies and facilities for the elderly with hearing loss.

This study is on the elderly people's use and experience of pet robots (companion robots). Applying companion robots for the elderly's daily lives can enhance their quality of life. Leisure is main activity of the elderly who are out of work. Therefore, the quality and diversity of leisure can affect the quality of their life. Companion Robots could provide them with more advanced and interesting experiences. Around the world, population aging becomes one of the most important trends in each country. The social and economic burden of aging is serious challenge on sustainability of the world, including S. Korea. The authors examine use of Companion Robots for elderly (from 50 years old to 90 years old). In this experiment, the authors study and measure many factors including system quality, interface quality, displeasure, enjoyment, willingness to reuse, perception on new technology. In regression analysis, intimacy(t=-2.006, p<.05) is significant factor on displeasure of Companion Robot. In another regression, displeasure of Companion Robot (independent variable) is significant factor on enjoyment(t=-3.327, p<.01) and willingness to reuse(t=-2.636, p<.01). Therefore, when elderly one feels less displeasure of Companion Robot, he/she feels more enjoyment and willingness to reuse. As a result, the elderly who don't familiar to new technology could improve quality of life and leisure activity by using companion robot.

Intercomparisons between four kinds of data have been done to estimate the accuracy of satellite observations and model reanalysis for middle and lower tropospheric thermal state over regional oceans. The data include the Microwave Sounding Units (MSU) Channel 2 (Ch2) brightness temperatures of NOAA satellites and the vertically weighted corresponding temperature of ECMWF GCM (1980-93). The satellite data for midtropospheric temperatures are MSU2 (1980-98) in nadir direction and SC2 (1980-97) in multiple scans, and for lower tropospheric temperature SC2R (1980-97). MSU2 was derived in this study while SC2 and SC2R were described in Spencer and Christy (1992a, 1992b). Temporal correlations between the above data were high (r${\ge}$0.90) in the middle and high latitudes, but low(r${\sim}$0.65) over the low latitude and more convective regions. Their values with SC2R which included the noises due to hydrometeors and surface emission were conspicuously low. The reanalysis shows higher correlation with SC2 than with MSU2 partially because of the hydrometeors screening. SC2R in monthly climatological anomalies was more sensitive to surface thermal condition in northern hemisphere than MSU2 or SC2. The first EOF mode for the monthly mean data of MSU and ECMWF shows annual cycle over most regions except the tropics. The mode in MSU2 over the Pacific suggests the east-west dipole due to the Walker circulation, but this tendency is not clear in other data. In the first and second modes for the Ch2 anomalies over most regions, the MSU and ECMWF data commonly indicate interannual variability due to El Ni${\tilde{n}$o and La Ni${\tilde{n}$a. The substantial disagreement between observations and model reanalysis occurs over the equatorial upwelling region of the western Pacific, suggesting uncertainties in the model parameterization of atmosphere-ocean interaction.

In this study we investigated the factors determining people's decision on whether to subscribe to private health insurance, on how many private health insurances they subscribe to and the average amount of monthly payment from subscribers of private health insurances. For analysis, logistic regression analysis and multiple linear regression analysis were conducted on the sample of 8,167 people using 2008 Korean Longitudinal Study of Ageing(KLoSA) data. From the analysis, whether to enroll in private health insurance is found to be greatly influenced by population and socioeconomic factors as well as regular exercise, smoking, cognitive function scores, subjective health status, hospitalization, the number of outpatient services, free primary health screenings benefits. We also found that number of private health insurances purchased is affected by age, household income, subjective health status, drinking, free primary health screenings benefits and that the average amount of monthly payment for private health insurances purchased is influenced by age, marriage status, economic activities status, subjective sense of hierarchy, household income, drinking, hospitalization. This study is expected to contribute to show the healthy role of private health insurance so that the desirable direction in expansion of health security policy in Korea can be explored further.

The problems of unemployment have been recognized as male problems even though the female unemployment problems are as significant as those of men since IMF. The women who have experienced insecure employment and lower wage than men in the labor market are having more serious economic difficulties after being unemployed. Especially economic problems of the unemployed female headed families are anticipated to be tremendous because the female heads do not have spouses who can act as a buffer seeking or beginning to work to reduce economic hardship. The purpose of this paper is to compare living conditions and utilization of the unemployment programs between male and female heads of the family who are unemployed and discouraged workers. It will examine the functionalism, human capital theory, and feminist perspectives on the cause of female unemployment in order to help understanding of their living situations after being unemployed. Then, it will compare the socio-demographic characteristics, their economic activities before being unemployed, their living conditions and changes in family life after being unemployed, their efforts to overcome unemployment and utilization of various government unemployment programs. It used the national data of National Unemployment Survey of Korean Institute of Health and Social Affairs conducted in 1998 and analyzed 283 female and 1,528 male family heads who are unemployed and discouraged workers. It reveals that the female family heads experienced lower economic status in the labor market before being unemployed, are having more serious economic hardship because of it, utilize more of the government programs such as public work and public assistance than the male family heads but less of the public loans for the unemployed. It recommends expansion of public work and public assistance, more vigorous advertisement of various unemployment programs, and active training of job creation technique for female family heads.

This study was conducted to analyze the dietary lifestyle of local Chinese consumers and to classify dietary characteristics according to their dietary lifestyle factors and dietary behaviors. This investigation was conducted for 1 month from 1 January 2017 targeting 300 adult males and females living in China using the online survey company surveymonkey. Four factors relating to dietary lifestyle were identified, gourmet factor, healthy factor, convenience factor and economic factor, and these were grouped into 4 clusters according to their dietary lifestyle factor scores. Group 1, the gourmet economy group, showed a high percentage of living alone and a high frequency of eating out, but a relatively low percentage of three regular meals per day. Their dietary lifestyle was sensitive to gourmet factors and economic factors, but less sensitive to health and convenience factors. Group 2, the wide interest group, contained a high percentage of individuals in their 30s, as well as more highly educated individuals and a higher income than other groups. Because their dietary lifestyle scores tended to be higher than those of other groups, they sought a variety of new foods and gourmet meals for enjoyment of dining and life, as well as well-being food materials and foods related to health. Group 3, the health economic group, constituted a family-type consumer group with lower income level than the other groups. Members of this group were seeking health food and natural food in their dietary lifestyle and tended to pursue a high economic profit ratio when purchasing food. Finally, group 4 showed a relatively higher percentage of women over 30 and individuals with a college level or higher education than the other groups. This group was more interested in health and taste than price and convenience, and showed the highest LOHAS orientation among middle aged Chinese women. Moreover, members of this group directly utilized their knowledge regarding nutrition in real life.

The purpose of this study is to identify the link that affects depression, a negative mental health problem for permanent rented apartment tenants, and to provide policy and practical support for reducing depression at the community level. To this end, 1,920 households of permanent rental apartment residents in K Metropolitan City were used in the survey. The results are as follows. First, more than half of the subjects surveyed 51.1% were found to have depressive symptoms. Second, among the demographic variables, the gender, age, single-person households, and social security benefits have a positive effect on depression. On the other hand, age squared and participation in economic activities were identified as factors to reduce depression. Third, among the residential community variables, the consideration for neighbors and their willingness to participate in the community were identified as factors to reduce depression. Fourth, physical health difficulties and mental health difficulties among the health status variables were identified as the determinants of depression. Based on the results of the study, the methods for intervention and follow-up studies to reduce depression in permanent rental apartment residents were discussed.

This study aims to explain the current upheaval in marriage that many young Korean men and women postpone or deny their marriage. In order to explain the delayed marriage, we need to understand the taste by which men and women choose their partners, the opportunity by which they find their ideational half in reality, and the context in which these values and opportunities of marriages intersect. This study examines the way in which the value and opportunities of marriage among Korean men and women have intersected differently in the changing economic conditions. Using KLIPS(Korea Labor Income Panel Survey, 1998-2002), differential effects of education and occupational status on marital time according to marriage cohort and gender are analyzed. Results find that the opportunity of marriage among men turns out to have been stratified significantly according to their educational achievement and labor status since the 1990s. For women, education and economic activities are likely to influence marriage decision in a discordant way; during the period of 1990-997, highly educated women are more likely than their counterparts to be married earlier while there is no significant difference according to economic activities. This implies that status homogamy has been intensified since the 1990s and many women with high motivation for social status are able to achieve a vicarious social status through marriage in a prosperous economy. For women married after 1998, however, the educational effect is insignificant but economic activity contributes to delaying marriage. This suggests that under the economic restructuring since the late 1990s, the constraint of opportunities finding decent jobs particularly for men results in the contingent change in women's perception about family roles and economic activities by reducing their expectation to achieve a vicarious status through marriage, but increasing their motive for their own economic activities.

Objectives: This study was to examine those life style factors which could affect the changes of health status indices such as ADL and IADL of the Elderly living in rural community. Methods: The subjects of the study were 1,295 elderly people of age over 65 years living in Gyungbook Sung-Ju area selected by random sampling for one month at October 1996. After 4 years, the follow-up study in those subjects were performed, ADL, IADL and general characteristics were measured. Those subjects who had shown high functional health status in first investigation were measured as how their health were changed in relation with their general characteristics and life styles in second investigation. Results: The factor analysis were performed in life style questions, and 6 factors composed of 15 questions of all were selected as the indices of life style. For ADL level, logistic regression analysis, age and educational level in men, and age and economic status in women had significant relation with health status change. Among life style factors, diet factor in men and diet factor, social activity factor in women were found to be significantly related. For IADL level, simple analysis showed that age in men and age, education level in women among general characteristics had related with health status change. Among life style factors, diet factor, stress relieving factor were related in women when general characteristics were also controlled diet factor, stress relieving factor were related in women. Conclusions: In order to prevent functional health status altering in the elderly, it is recommended that the intervention which could promote healthy life styles such as good diet habit, active social participation, and pertinent stress relieving should be considered.

The purpose of this study is to examine major factors that affect patterns of living arrangements of older Korean noncitizens in the United States using the 1990 8% Public Use Microdata Sample(PUMS). In order to do so, I analyzed the effects of four factors including acculturation(English proficiency and Age at migration), economic circumstances(Personal Income and Supplemental Security Income: SSI receipt), health status(Mobility and Personal care limitation), and the ethnic community. The results show that acculturation and economic circumstances play an important role in determining the patterns of living arrangements among older Korean aliens, whereas the health status and the ethnic community do not show consistent effects. Regardless of marital status, the impact of age at migration is positively associated with solitary living of older Korean noncitizens, though, the effect of English proficiency show the opposite direction in accordance with marital status. That is, among nonmarried elders, those who cannot speak English are more likely to live alone. The case is reverse for married elders. The impact of economic feasibility is also positively associated with independent living arrangements. Those who receive SSI are much more likely to live apart from family, and elders whose annual personal income between $5,001 and $10,000 have the greatest propensity of solitary living-a large proportion of their income source is SSI. Individuals who receive SSI are also qualified to collect Medicaid, food stamps, rent subsidies, and other welfare benefits. In a sense, the economic feasibility provided by welfare benefits is the key determinant of independent living of older Korean noncitizens. Therefore, the recent welfare reform which denies legal aliens welfare benefits such as SSI and food stamps will severly affect the present living arrangements of older Korean aliens, and give economic burden to their family member The findings also show that there are significant differences within the elderly Korean Americans in terms of demographics, income, fertility, health status, and patterns of living arrangements by U.S. citizenship status. In particular, after controlling for age at migration as a proxy for acculturation, there is a statistically significant variation in living arrangements between elderly Korean noncitizens and naturalized citizens. For both theoretical and methodological reasons, future research on minority aging needs to investigate the concept of U.S. citizenship status for its impact on patterns of living arrangements among the minority elderly.
