The aims of this study were to identify (a) the social network contact frequency of the elderly with children, relatives, and friends; (b) the impact of contact frequency (face-to-face/non-face-to-face) on life satisfaction of the elderly; and (c) the moderating effect of digital capabilities of the elderly on the relationship between social contact frequency and life satisfaction. Data were obtained from the National Survey of Older Koreans 2020. The sample comprised 6,119 adults aged 65+ who were in single or couple households. The principal findings were as follows. First, couple households, higher levels of education, and better health status increased life satisfaction of the elderly. Second, the higher the frequency of face-to-face contact with children and the higher the frequency of non-face-to-face contact with friends, the more positive the effect on life satisfaction of the elderly. Third, the interaction effect of the digital capabilities of the elderly differed according to children, relatives and friends. There was a significant and positive moderating effect on the relationship between life satisfaction and the frequency of face-to-face/non-face-to-face contact with children and the frequency of face-to-face contact with relatives. Conversely, there was a significant negative effect on the relationship between life satisfaction and the frequency of face-to-face/non-face-to-face contact with friends. By examining the impact of non-face-to-face contact on life satisfaction of the elderly in the era of digital transformation, the findings have significance in that they provide basic data to support policies and education programs aimed at improving the digital capabilities of the elderly.

Background: As South Korea is becoming an aged society very rapidly, the increase in osteoarthritis prevalence raises various public health issues in this country. This study aimed to explore the socio-demographic factors associated with osteoarthritis in the current Korean elderlies. Methods: Using the National Survey of Korean Elderly data (2014, 2017), we analyzed 20,326 elderlies (males, 8,248; females, 12,078) and conducted multivariate logistic regression analyses by sex. The dependent variable is whether a participant was diagnosed with osteoarthritis or not. Independent variables of interest is socio-demographic factors such as age, marital status, household type, residential area, household income, religion, the longest job, the number of close relatives, the number of close friends, and survey year. Control variables are various health behavioral factors and disease-related factors. Results: Prevalence of osteoarthritis was 19.2% in male elderlies and 47.0% in female elderlies. According to the results of the multivariate logistic regression adjusted for all studied control variables, the odds ratio (OR) for having osteoarthritis of under-elementary school graduates (their counterpart was college graduate group) was 1.81 (95% confidence interval [CI], 1.29-2.52) in males and 1.67 (95% CI, 1.12-2.47) in females. The OR of those having a job in agriculture & forestry fishery as their longest job (their counterpart was those who had never participated in labor force during their lifetime) was 5.07 (95% CI, 1.46-17.58) in males and 1.49 (95% CI, 1.27-1.74) in females. In males, the second-low quartile group in household yearly income (their counterpart was the highest quartile group) had the OR of 1.22 (95% CI, 0.98-1.53). In females, the OR of those having a religion of Buddhism (their counterpart was those having no religion) was 1.20 (95% CI, 1.07-1.35) and the OR of those who had no relatives (their counterpart was those having more than 3 close relatives) was 1.31 (95% CI, 1.10-1.56). Conclusion: This study found that in Korean elderlies, education, the longest job, household income, religion, and the number of close relatives are associated with their suffering from osteoarthritis. Further study and designing appropriate interventions are needed to alleviate current and future individual and socioeconomic burdens of osteoarthritis in an aged society like South Korea.

For linear operators between Banach algebras "spectral boundedness" is derived from ordinary boundedness by substituting spectral radius for norm. The interplay between this concept and some of its near relatives is conspicuous in a result of Curto and Mathieu.

This study attempted to investigate the effect of housemaker's interest in dietary life on the knowledge of cooking principles and cooking methods, and on the daily meal management. Housemakers whose age ranged from 20 to 50 were surveyed in their residence. The results of this study were as follows. First, the level of interest in dietary life was positively related with ages, education and income levels. Moreover, housemaker who did not work or did not take care of relatives had higher level of interest in dietary life than those who did. Second, most housemakers bought foods and prepared a meal by themselves. The average time spent in preparing meals was 2 to 3 hours, and the number of side dishes cooked per day expect for the main dish was 5.46 percent of the total respondents ate out more than once a month for a 'family tie'. Third, there was no relation between the knowledge of cooking principle and the variables such as ages, education and income levels. Fourth, the level of the knowledge of cooking method about Korean traditional dishes was positively related with ages, education and income levels. In addition, housemakers who did not work or did not take care of relatives had less knowledge of Korean traditional dishes than those who did. Finally, the interest in dietary life was significantly correlated with the knowledge of cooking principle and cooking method of Korean traditional dishes.

The purpose of this study was to examine the relationship between social networks and perceived self-competence. The subject were 350 third and sixth graders selected from a public elementary school in Seoul. The children were administered the Pattison Psychosocial Network Inventory and The Self Perception Profile for Children. Three major questions are addressed; l)age changes 2)sex differences, and 3) the relation between the characteristics of social networks and self-perceived competence. Data were analyzed by pearson's product moment correlation, one-way ANOVA. Proportion measures were also used since they had allowed for the observation of relationship between two subsets of people within given categories(e.g.,the number of relatives divided by the number of relatives plus nonrelatives). The effects of age and sex of child on the number and daily contact with kin, nankin, peers, adults, males, and females were found. Sixth graders had a larger number of adults than third graders. While children had a greater number of adults than peers, they had more contact with peers than with adults in their network. It was found that boys had greater number of people in their network than girls. And boys had a larger number of and more contact with males, and girls had a larger number of more contact with females. The structure of childrens' social networks structure were correlated with perceived self-competence.

The purpose of this study was to explore college students' expectations on post-college housing and sources of finance to afford housing costs; and perception of housing cost burden. Between May 28, 2012, and June 17, 2012, a questionnaire survey was conducted to undergraduate students in university-A located in non-capital region and 465 useable responses were collected. Major findings are as follows: (1) About 60% of respondents expected to live apart from their parents or relatives within two years from college graduation; (2) Majority of respondents who expected to live apart from their parents or relatives expected to rent housing units and compact non-traditional housing types such as studio units; (3) Major source of finance the respondents expected to afford post-college housing costs was financial supports from their parents and families; (4) Housing cost burden were perceived to have influence even on job decision and respondents with lower parents' income perceived housing cost burden more influential; and (5) In spite of respondents' low financial independence to afford post-college housing costs, finding housing units in areas with relatively lower housing costs seemed not to be an important consideration when choosing post-college housing.

Introgression from genetically modified plants (GMPs) may be dependent on the genetic similarity to wild relative plants. In Korea, many wild plant species are botanically related to the cultivated plants that have a potential to be genetically transformed. The controversy for hazards of GMPs is continuing because the studies on gene flow or introgression are little. Based on the systematic criteria, we have surveyed Korean wild plant species that showed the similarity to cultivating crops. The consideration for feasibility of genetic pollution (introgression of transgene) is necessary for the successful accomplishment in the practical use of GMPs. Although the detrimental effects of GMPs on wild relatives have not been clearly verified, Korean wild plant species related to crop plant (potential GMP) have to be investigated with respect to the introgression. Korean flora consists of ca. 5,500 species. Among them, 1,448 species are classified as weed species (966 native, 325 naturalized, and 167 escaped ones), which is vulnerable to GMPs in term of introgression. We suggested the principal Korean wild plants related to major crops that might be affected by GMPs via introgression. The investigated species herein are selected based on the morphological and phenological relationship. It is necessary to verify the genetic relationship between cultivated plants and wild relatives sing more precise molecular techniques, which provide the information of likelihood for the introgression of transgene.

This study investigated whether social and psychological factors were related to nutritional status of the elderly. Food habits, social contacts and psychological the test score were collected from 86 institutionalized elderly women aged 65-96 in Chon-buk area. Social health status was measured by score of social contacts with others. Depression, self-esteem and locus of control were measured to evaluate psychological health status by using Zung DSI(Depression Status Intentory), Rosenberg SES(Self-esteem scale) and Rotter's vs external control, respectively. Social contacts of the total subjects were lowered, and in the group of over 85, contacts with relatives were significantly decreased compare to under 85 years of age groups. Psychological health status such as depression and self-esteem were also lowered, but locus of control showed internal control that indicates positive attitude to eating behavior. Most of the nutrients intake were positively correlated to self-esteem scores(p<0.05), but not to nutritional risk index score. Intake of vitamin C was related to social health status as well as psychological health status. Increasing the number of contact with relatives, intakes of carbohydrates, fiber, vit B1, vit C, Ca and P were elevated(p<0.05). As the score of self-esteem increased, intakes of fiber, Fe, vit B1, niacin, vit C, and vit A were increased. It is suggested that social activity and health education programs will be needed to improve the nutritional status of the institutionalized elderly.
