Purpose: The aim of this study was to investigate the relationship between social support and quality of life (QOL) in elderly people and to examine potential cross-cultural differences. Methods: The author surveyed 82 elderly people, over the age of 65, residing in a nursing home in a Korean rural area and 73 Korean immigrants living in Houston Texas USA who were also elderly. The degree of social support was measured with 20 questions that were answered using a 5 grade scale. The quality of life was measured in 5 fields (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each scored using a 3 grade scale) with EUROQOL EQ-5D. Results: The mean score of social support was 65.43 for domestic Korean elderly people (range: 26 to 98); it was 73.43 for elderly Korean Americans (range: 26 to 100). The score was lower for domestic Koreans despite the traditional environment (p<0.05). Regarding QOL, 61% of domestic Korean elderly people complained of pain/discomfort and 47.5% appeared to have anxiety/depression, 30.5% complained of limitations in mobility, 20.7% reported limitations in usual activities, and 14.6% had limitations in basic self.care activity such as washing or dressing. A similar proportion of Korean American elderly had limitations in usual activities (19.2%) and self care activity (9.5%). But significantly fewer complained of anxiety/depression (16.5%, p<0.01) or pain/discomfort (38.3%, p<0.01). The major differences in psychological domains of QOL may be related to the degree of social support and the difference in the socio.cultural environment. Conclusion: Social support is a major determinant of QOL, especially for psychological domains, and these relationships are under the influence of the socio.cultural environment.

The beneficial effects of fruits, vegetables, and beverages on human health have been attributed to their antioxidant activities. Therefore, antioxidant activity of food products is recognized as one of the important parameters in determining their functional values. Until now, antioxidant activity has been measured by various chemical and biological methods; however, many factors confound the reliability and reproducibility of measurements of antioxidant activity of food. In vitro methods may provide a useful indication of antioxidant activity but their results may not translate to the human biological system, while in vivo tests are difficult to carry out due to the intricate processes of uptake, cellular transportation, and metabolism of individual antioxidant components. Therefore, as long as these limitations exist, our best option is to measure the antioxidant activity in food directly. This review briefly summarizes currently available methods for the measurement of antioxidant activity in food and examines their respective validity.

Objectives : This study aimed to identify the factors influencing insufficient physical activity in community-dwelling elderly individuals with dementia. Methods : Data were analyzed using a 2014 Survey of Living Conditions of Elderly Individuals. Metabolic Equivalent Task (MET) hours were calculated using self-reported weekly frequency, duration, and types of physical activities to measure the degree of physical activity. Results : Mean MET hours were $4.03{\pm}8.59$. Factors influencing insufficient physical activity included limitations in activities of daily living (ADL), lower frequency of social group participation and unsatisfactory relationships with friends or community. When demographic factors were adjusted, patients with ADL limitation had 11.2 times higher risks of insufficient physical activities than those without. Conclusions : Community-dwelling elderly with dementia performed low levels of physical activity. Further research is needed to develop strategies to encourage physical activity participation in this population.

This study was to identify various personal characteristics between those having a helper and those not having a helper for ADL and IADL performance in noninstitutionalized elders. Secondary analysis was done with the data collected in 1994 national survey of aged householders. Of the elders with ADL limitations $47.8\%$ had no helper. while $26.2\%$ of those with IADL limitations had no helper. Those elders with a helper experienced more limitations in ADL and in IADL than those with no helper. Most of the helpers were family members. whereas very few had a formal helper. Age period and subjective economic status were significantly different between the groups with a helper and with no helper for both ADL and IADL. Compared to the elders with a helper. those elders with no helper had fewer children living together. whereas they had more grandchildren. They also had more contacts with friends or neighbors. Health status. in general. was worse in those elders with a helper than those with no helper. Logistic regression analysis revealed that ADL and IADL limitations had largest influence on having an ADL helper. The odds ratios for low levels of subjective economic status were very high. As for having an IADL helper. IADL score was the most important predictor. In particular. ADL limitations had a negative effect on having an IADL helper. This finding may indicate the urgency of ADL needs. which leads to the lack of an IADL helper when both ADL and IADL limitations are present. Considering the nature of ADL. those disabled elders with low economic status need public support for their daily activities and for home visiting nursing services. There should be studies of examining the adequacy of help in satisfying basic needs for performing ADL and IADL in elders.

Purpose: The purpose of this study was to help the numerous health care workers who participate in the rehabilitation of stroke patients by understanding how limitations on the activities of stroke patients affect the health-related quality of life and depression. Methods: We investigated 527 stroke patients from the Korean's National Health and Nutrition Examination Survey (KNHANES, 2013-2018). The subjects were divided into two categories: with and without activity limitation. A medical doctor's diagnosis of depression and the EQ-5D, which measures life satisfaction connected to health, were the study's factors. Based on their level of activity limitation, the individuals' depression and health-related quality of life were compared. The odds ratios relating to activity limitation's relationships with depression and stroke patients' quality of life were computed using logistic regression analysis. Results: The diagnosis of depression in subjects with activity limitation was 16.0%, while in those with no limitation on activity it was 5.6%, and the EQ-5D index was 0.67±0.02, 0.85±0.01. For every item on the EQ-5D, there existed a significant difference in the odds ratio. Furthermore, when comparing depression with activity limitation to non-activity limitation, the odds ratio was 4.09 (2.12-7.788). Conclusion: Limitation of activities of stroke patients significantly reduces the health-related quality of life and increase the probability of depression. Therefore, treatment of stroke patients should be approached taking into consideration their psychological condition. It is also deemed necessary to have a systematic and continuous rehabilitation program.

Seaweeds are a potential source of minerals, essential amino acids, fatty acids, proteins, and various bioactive compounds such as antioxidants. The higher water content of seaweeds reduces the shelf life and this requires the appropriate drying method. The drying conditions play a major role in the conservation of nutrient composition in dried seaweeds. In recent years, the seaweed industry has used many different drying methods with advantages and limitations. Hybrid hot-water Goodle dryer (HHGD) which is a special dryer mixed with hot-water and a Korean traditional heating system (Goodlejang) might be a solution to avoid these limitations. The present study evaluated the effect of drying conditions in HHGD on nutrient composition and bioactivities of brown seaweeds. Moreover, freeze-dryer (FD) and HHGD were employed in this study to compare the dried outputs obtained from four brown seaweed species. The present study aims to evaluate the effect of the hybrid hot-water Goodle drying method (HHGDM) on the nutritional composition and antioxidant activity of dried seaweeds. AOAC standard methods were used to analyze the proximate composition of dried samples and their 70% ethanol extract. The intracellular and extracellular antioxidant activities were evaluated using Vero cells and electron spin resonance (ESR) spectrometer respectively. High performance liquid chromatography, apoptotic body formation, and in-vivo experiments were used for further confirmation of the quality of dried output. The proximate composition results obtained from drying in HHGD and FD did not exhibit any significant difference. Moreover, the seaweed extracts from the dried seaweeds by HHGD and FD dryings were also not different and both significantly down-regulated in-vivo and in-vitro oxidative stress. Furthermore, the high performance liquid chromatography results revealed that the two dryers did not make the major peaks different in the chromatograms. Freeze-drying method (FDM) provides elevated quality for dried output, but there are limitations such as high cost and low capacity. The results from a novel HHGD did not provide any significant difference with the results in FD and expressed a potential to avoid the limitations in FD. Overall, these findings solidified the applicability of HHGD over FD.

Horticultural therapy, as a kind of complementary alternative therapies using nature as a medium, is an intervention method that can be applied to various subjects by utilizing horticultural activities that anyone can enjoy as a leisure activity. This research defined the resilience of individuals as a personal characteristic, and examined differences in the intervention effect of horticultural activities depending on the level of resilience. The results obtained in this study can be utilized in planning a horticultural activity program and setting the purpose and goals of horticultural activity programs. The subjects of this study were divided into the high resilience experimental group (Group A), the low resilience experimental Group (Group C), the high resilience control group (Group B), and the low resilience control group (Group D). The experiment was conducted in the campus of G University from September to November 2017, and the experimental group participated in the program once per week, a total of 10 sessions. The Korean version of the Connor-Davidson Resilience Scale, autonomic nervous assessment, and the interpersonal relationship change scale were carried out as pre- and post-assessment. Statistical analysis was performed using a non-parametric test. Group A showed statistically significant positive changes in relaxation of physical tension and stability. In conclusion, those with high resilience showed the higher intervention effects of horticultural activities on physical relaxation and stability than those with low resilience. However, there were some possible limitations in this study. Since the number of subjects was small and subjects were limited to college students, it is impossible to generalize the results of this study. Therefore, it is necessary to conduct follow-up studies to address and overcome these limitations.
