Purpose: The purpose of this study was to investigate the current state and trends of factors influencing the quality of life in low- income elders living at home. Methods: To carry out this study we established the patient, intervention, comparison, outcomes (PICO) strategy, reviewed 241 published documents from both national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria alone. The quality of selected references was assessed using 15 questions. Two reviewers independently examined titles and abstracts and assessed whether each met the predefined inclusion and exclusion criteria. Results: The following factors were significantly associated with quality of life in low- income elders: (1) demographic factors such as number of children, income, and age; (2) health - related factors such as joint exercise capacity, activities of daily living/instrumental activities of daily living, health perception, health promotion behavior, and depression; and (3) socio environmental factors such as family support, community-based service program, leisure activity, and the number of neighborhoods involved. Conclusion: The results of our study provide a definite basis for the development of a policy strategy to improve the quality of life in elders with low income and we hence strongly recommend that any strategy to improve the quality of life in low-income elders be based on the results of our study.

Purpose: This study was aimed to identify the factors related to the health related quality of life (HRQoL) in elderly women. Method: This study used data from cross-sectional surveys conducted for the 2005 National Health and Nutrition Survey, which was performed by using a face to face interview method. Data was analyzed by ANOVA, t-test, logistic regression and multiple regression using the SPSS program. Demographic characteristics, subject health state, activity limitation, K-ADL, K-IADL, EQ-5D were included in the study instruments. Result: The mean HRQoL index in the subjects was 0.68 $\pm$ 0.25. The significant predictors of the HRQoL were health status, activity limitation, activities of daily living (ADL), instrumental activities of daily living (IADL) and income. The factors accounted for 41.0% of variance in the health related quality of life of female elderly. Conclusion: These results may contribute to development of nursing strategy to improve health related quality of life. The health related quality of life program for the elderly should be planned based on results of the study.

Salmonella is a common zoonotic and foodborne pathogen that causes high morbidity and mortality in developing countries. In this study, we established and validated a polymerase spiral reaction (PSR) assay which targeted the conserved invasion gene (invA) of Salmonella by SYBR Green I indicator methods. Subsequently, assays for determination of the optimal conditions for optimal specificity and sensitivity of PSR were performed. We performed comprehensive evaluations using loop-mediated isothermal amplification (LAMP) and real-time PCR. A total number of 532 samples of daily food were analyzed by PSR. Twenty-seven bacterial strains were tested in the specificity assay, from which positive results were obtained only for 14-Salmonella strains. However, none of the 13 non-Salmonella strains was amplified. Similarly with LAMP and real-time PCR, the detection limit of the PSR assay was 50 CFU/ml. The PSR method was also successfully applied to evaluate the contamination with Salmonella in 532 samples of daily food, corroborating traditional culture method data. The novel PSR method is simple, sensitive, and rapid and provides new insights into the prevention and detection of foodborne diseases.

The goal of this study was to investigate how daily experiences of schoolwork and leisure activities explained cultural differences in levels of adolescent depression. A combined sample of 58 high school seniors in Korea and 62 high school seniors in the United States reported time use patterns and affect states in daily activities and levels of depression. The time use pattern in daily independent study during class hours and in active leisure activities significantly explained cultural differences in levels of depression. Affect states in all schoolwork activities and passive leisure activities also significantly explained cultural differences in levels of depression. These findings suggest that Korean adolescents' experience of 'exam hell', particularly the lack of active leisure activities and more negative emotional experiences of daily activities are partly responsible for their higher depression relative to American counterparts.

Since the global positioning system (GPS) has been included in mobile devices (e.g., for car navigation, in smartphones, and in smart watches), the impact of personal GPS log data on daily life has been unprecedented. For example, such log data have been used to solve public problems, such as mass transit traffic patterns, finding optimum travelers' routes, and determining prospective business zones. However, a real-time analysis technique for GPS log data has been unattainable due to theoretical limitations. We introduced a machine learning model in order to resolve the limitation. In this paper presents a new, three-stage real-time prediction model for a person's daily route activity. In the first stage, a machine learning-based clustering algorithm is adopted for place detection. The training data set was a personal GPS tracking history. In the second stage, prediction of a new person's transient mode is studied. In the third stage, to represent the person's activity on those daily routes, inference rules are applied.

Both direct and indirect courses are studied in this research to study the effect of fathers' daily stress, child-rearing involvement and marital conflict on children's emotional intelligence. The participants were 281 parents of children aged between 3 to 5 attending 9 kindergartens in Seoul and the Gyeonggi-do, Jeolla-do, and Gyeongsang-do areas. The data was collected by the questionnaire method. Collected data for the study was analyzed using the Structural Equation Model with the AMOS 16.0 program. The main points of this research are as follows: First, the direct course of fathers' daily stress did not appear to have a significant effect on children's emotional intelligence. Second, fathers' daily stress has an indirect effect on children's emotional intelligence through marital conflict. That is, the higher level of stress in the father's daily life, the deeper marital conflict that is found. And the deeper the marital conflict that exists, the lower child's emotional intelligence that is shown. Third, the direct course of the fathers' child-rearing involvement did not appear to have a significant effect on children's emotional intelligence. Fourth, the father's child-rearing involvement has an indirect effect on children's emotional intelligence through marital conflict. That is, marital conflict decreases as the father becomes more involved in child rearing. In addition, the lower level of marital conflict that exists, the higher child's emotional intelligence.

Purpose : In this study, we applied a computerized cognitive rehabilitation program (CoTras-C) for children with cerebral palsy. Research was conducted to investigate the impact of upper limb function, sensory function, and activities of daily living. Methods : The study period lasted 10 weeks from October 2019 to December 2019. The study subjects were 12 subjects according to the selection criteria, and a computerized cognitive rehabilitation program (CoTras-C) was conducted twice a week for 30 minutes before and after the application of basic occupational therapy. Results : As a result of the computerized cognitive rehabilitation program, scores of upper limb function (QUEST), sensory function (SSP-2), and daily life activity (WeeFIM) were significantly improved (p>.05). From the result of examining the motor area, improvement in fine-motor function and protective extension through touch pad or controller operation was found. It also showed improvement in activities of daily living including motor and activities of daily living including social cognition. In the sensory function evaluation, it was not significant in movement sensitivity. Significant differences were shown in the items excluding olfactory/taste sensitivity. Conclusion : The application of the computerized cognitive rehabilitation program (CoTras-C) showed significant results in upper limb function, sensory function, and daily life activities of children with brain lesions. Based on these results, future studies need to generalize the study by expanding the age or population of children with brain lesions, or by expanding the diversity of diseases and environments.

Purpose: This study was conducted to provide occupational performance evaluated by stroke patients themselves as an intervention according to the periods of its outbreak and examine the effects of it on their activities of daily living and life quality by using the Canadian Occupational Performance Measure (COPM). Method: The subjects of this research were divided into nine persons for the experimental group receiving the client-centered occupational therapy intervention and another nine for the control group getting the conventional occupational therapy intervention. And the intervention was performed for 30 minutes, three times a week, for total eight weeks. The level of activities of daily living was evaluated by the Functional Independence Measure (FIM), and life quality was tested by using SS-QOL. Results: First, about the difference of change in the FIM points of the two groups, there was statistically significant difference in Mauchly's sphericity verification (p<.05). Second, about the difference of change in the SS-QOL points of the two groups, there was statistically significant difference in Mauchly's sphericity verification (p<.05). Third, regarding the coefficient of difference in the change of FIM and SS-QOL points according to the two groups, there existed statistically significant correlation in all the evaluations of before, in the middle of, and after the FIM points and also before, in the middle of, and after the SS-QOL points (p<.05). Conclusion: With the findings of this research, we can see that the client-centered occupational therapy training group shows more improved activities of daily living and life quality than the conventional occupational therapy training group. Therefore, it is expected that the client-centered occupational therapy training will be applied usefully to clinical situations as an intervention to improve stroke patients' activities of daily living as well as life quality.
