Assuming that EEG(electroencephalogram), which is generated by a nonlinear electrical of billions of neurons in the brain, has chaotic characteristics, it is confirmend by frequency spectrum analysis, log frequency spectrum analysis, correlation dimension analysis and Lyapunov exponents analysis. Some chaotic characteristics are related to the degree of brain activity. The slope of log frequency spectrum increases and the correlation dimension decreasess with respect to the activities, while the largest Lyapunov exponent has only a rough correlation.

PURPOSE: Many studies have reported the improvement of cognition through physical activity among subject with dementia. This study aimed to whether the current studies supports that physical activity intervention is efficacious on cognitive performance in subject with dementia. METHODS: Two independent reviewers searched National assembly library, RISS, KISS (2005-2015) using the concepts of dementia, exercise, and physical activity. We included randomized controlled trials that examined the efficacy of physical activity in subject with dementia. A meta-analysis was performed to estimate the effect sizes cognition with CMA (Comprehensive Meta-Analysis, version 2.2.064) soft-ware program. Nine randomized controlled trials were included, providing data from 133 individuals and excluding those failing to criteria of this study. RESULTS: The meta-analysis showed that physical activity intervention had a rather small effect sizes of 0.36 (95% confidence interval 0.14-0.59) on cognition performance in subject with dementia. Outcome measurement were MMSE-K (Mini-mental state examination Korean version) and LOCTA (Loewenstein Occupational Therapy Cognitive Assessment). We found heterogeneous among studies and there was difference between the studies (Q = 19.63, d(f)=12, $I^2= 38.88$). CONCLUSION: The present analysis suggests that physical activity interventions have the low effect sizes on cognition performance in subject with dementia Further studies will be required to develop the various programs for improving the cognitive performance in subject with dementia.

The purpose of this study is to determine the suitable illuminance model of an urban neighborhood park. To this end, 1 dependent variable and 11 independent variables were set, and multiple regression analysis was applied to find correlation between variables and the model. The results of this study are as follows; 1) Among 11 independent variables abstracted to study suitable illuminance model of an urban neighborhood park, as a result of analysis on correlation between suitable illuminance of a dependent variable and activity space by using dummy variables, activity type and illuminance by spaces the suitable illuminance required for an urban neighborhood park was much influenced by activity type, and the fact that the activity was not limited to a specific space. 2) As a result of multiple regression analysis, independent variables influencing the suitable illuminance model of an urban neighborhood park were activity space, illuminance by spaces, seated activity, standing activity, and sporting activity. And, for relative contribution of independent variables to suitable illuminance, activity with sporting showed an importance 22 times higher than seated activity. When the central square(Sp_1) of activity spaces was set to reference category using dummy variables, it showed a contribution 52 times higher than sorting space(Sp_7) and the central square as the most important variable. 3) It was analyzed that suitable illuminance of an urban neighborhood part was most influenced by sporting activity but the relative contribution of a sporting space where activity with sporting occurs was least in view of the function of the space. Very high illuminance is required to accept high activity, and if illuminance at a certain space becomes too high, it may influence the illuminance of other spaces, and may consequently have a negative effect on the suitable illuminance of an urban neighborhood park. The results of this study were mainly for teenagers and young adults in their twenties, so further concrete studies which consider gender and a wider age range are needed in the future. Based on subsequent study, suitable illuminance by spaces shall be suggested.

The study aims at investigating the causal relationships among leisure expenditures, leisure activity participation and leisure satisfaction of adult consumers. Data were collected from 415 adult consumers in Ulsan. ANOVA, multiple regression, and path analysis were used for the statistical analysis. The results indicated that marital status, household income and subject's attitude toward leisure had significant impacts on leisure expenditures, while their satisfaction with financial status, household income, leisure plan, their attitudes toward leisure and personal acquaintanceship significantly affected leisure activity participation. To leisure satisfaction, their satisfaction with financial status, the attitudes toward leisure, leisure expenditures and leisure activity participation were positively related, and leisure plan was negatively related. The results of path analysis showed that marital status, household income, the satisfaction with financial status, their attitude toward leisure, leisure plan, personal acquaintanceship, leisure expenditures, and leisure activity participation had direct or indirect effects on leisure satisfaction.

The information obtained from the analysis of respiratory muscle elecromyographic (EMG) activities provides a mean for studying muscular activity in relation to the ventilatory process. Thus, in order to comprehend the airflow pattern and its brain control, signal processing is required to characterize respiratory muscle activity. This paper presents a computerized method for the analysis of the electrical activity of the respiratory muscles of premature lambs, and focuses upon the automatic determination of respiratory timing points such as onset and cessation points of the burst activity. Based on experimental results, reliable timing points can be obtained using the proposed methodology.

The purpose of this study was to examine the structural relationships between attributes, satisfaction, and behavioral intention of rural tourism activity. For this study, an onsite survey was conducted to tourists of 35 rural tourism farms. A total of 408 samples were collected for the analysis. The SPSS 20.0 and AMOS 18.0 statistical package were used for frequency, reliability, exploratory factor, confirmatory factor, and path analysis. Through exploratory factor analysis, four dimensions of rural tourism activity attribute were identified from 20 variables: 'human resource', 'activity', 'rural culture', and 'facility and environment'. The results of structural equation modelling indicate that 'human resource', 'activity', 'rural culture' had positive effect on behavioral intention. Through the results, agritourism farm operators will be able to develop effective marketing strategy and management skill.

Pick-up/delivery of consumer goods to offices, shops, and restaurants in order to support urban lives is one of the most vital activities in a city. With economic growth and technological innovation, a greater variety of goods have come to be supplied, and pick-up/delivery of consumer goods has become more complex. Efficient urban goods movement in Central Business District(CBD} starts with an efficient system for loading/unloading, and pick-up/delivery activities. Loading/unloading activity may be carried out on-street, or on especially designated space inside or outside buildings. Therefore, purpose of this study is to clarity the efficient urban goods movement in CBD(also called the pick-up/delivery activity) from the three different types of loading/unloading facilities. For this purpose, the differences in loading/unloading and truck-trip activity time of each loading/unloading facility was compared by performing the simulation analysis.

PURPOSE: This study is a data analysis study to determine the physical health problems and reasons for disabilities and activity limitation rates that limit daily life and social activities among the elderly population aged 75 or older in Korea. METHODS: This study data was extracted from the raw data of the 7th National Health and Welfare Survey (2016-2018). The subjects of this study were 1,995 elderly people (823 men, 1,172 women) aged 75 years or older. The collected data were analyzed using frequency analysis and logistic regression analysis. RESULTS: From 2016 to 2018, the activity limitation rate among the elderly population aged 75 or older in Korea was 20.6% for men, 24.6% for women, and 23.1% overall. The three major diseases with the highest frequency of activity limitations were back and neck problems (36.5%), arthritis and rheumatism (28.7%), and knee and leg pain (14.7%). Activity limitation due to old age was found to be 13.1%, making it the fourth most frequent reason. The rate of activity limitations due to mental retardation and obesity was found to be 0%. The three major activity limitation rates were significantly related to gender. CONCLUSION: The main diseases causing activity limitations among the elderly population aged 75 or older in Korea were back and neck problems, arthritis and rheumatism, and musculoskeletal diseases such as knee and leg pain. Therefore, it is believed that it can be used as basis data for reducing the activity limitation rate of the elderly population in the aging era.

This study was done to research the relationship between State-Trait Anxiety and Sexual activity of pregnant women. The subjects for this study were 200 pregnant women from 2 hospitals located in a urban area. The data was collected through questionnaires which was developed by Spielberger, from to, 1982. The content of the questionnaire consist of following 2 categories of Anxiety and Sexual activity; (1) State Anxiety, (2) Trait Anxiety and (3) Sexual activity included sexual drive, number of sexual intercourse, and length of sexual intercourse. Analysis of data was done by use percentage, T-test, x$^2$-test, ANOVA and pearson correlation coefficiency. The findings of this study are as follows: 1. The mean score of state Anxiety and Trait Anxiety of respondents were 43.06, 44.19, therefore Trait Anxiety was higher than state Anxiety. 2. A significant state Anxiety and Trait Anxiety were not found among general characteristics with age, education level and religion 3. In the analysis of correlation among state Anxiety, Trait anxiety and Sexual activity, the Trait Anxiety was positively correlated with the State Anxiety. (r=.3877, p=.000) It was support the fact that the higher level of Trait anxiety, the greater was the State anxiety. 4. And the state anxiety was negatively correlated with number of sexual intercourse. (r=-1518, p=.016) Therefore, the higher the state anxiety, the lower sexual activity. Or the lower sexual activity, the higher the State Anxiety. 5. Also, in the analysis of factors affecting sexual activity, only the variable of age showed a significant correlation to number of sexual intercounse. That is the younger, the higher number of sexual intercounse. (r=. -. 1380, p=.026).
