Objectives: This study identified how personal characteristics, healthy behavior and social capital might influence on physical activity of adults. Methods: This study used data from the health survey of a city of Korea. We surveyed 1,000 adults sampled by stratified sampling methods from 67,889 households. Outcome variable was the stage of physical activity which was broken into 5 categories. Sociodemographic factors, healthy behavior, self-rated health status and social capital were used as control variables. Sociodemographic factors included age, sex, educational status, economic status measured by deprivation score, residential period within survey city. Social capital was measured by Integrated Questionnaire for the Measurement of Social Capital (SC-IQ). This study used chi-square test and ordered logistic regression models to examine the associations between independent variables and physical activity. Variables were added to the regression model in three groups using a hierarchical approach. Results: Physical activity was significantly more likely to become active if they have higher educational status, healthier behavior. Among the six dimensions of SC-IQ, only "groups and networks" that is structural dimensions of social capital and "trust and solidarity" that is cognitive dimensions of social capital were significantly related to physical activity of adults. We found that a person having higher density of membership and having larger size of networks showed the high possibility of active physical activity. A person having high solidarity was significantly associated with physical activity, but general trust was inversely related to physical activity. Output dimensions of social capital did not show significant relationship to physical activity. Conclusion: We found that social capital is useful concept to explain health behaviors like physical activity. However we must consider social, cultural and political context of the study to evaluate the effect of social capital to health status and health determinants and to capture the exact meaning of relationship between them. We suggest further researches to refine the concept of social capital and to explain the relationship of social capital to diverse health determinants.

The purpose of this study is to make an empirical analysis of the influencing factors of consumer purchase intention of ginseng products, one of the specialties of jilin province in china, on the basis of expanding the theoretical model of planned action at the level of perceived value, so as to better grasp consumer purchase behavior of ginseng products. In this study, a questionnaire survey was conducted among ginseng product consumers living in jilin, and 360 valid samples were statistically analyzed using SPSS 23.0.The analysis results show that behavioral attitude, subjective norms, cognitive behavior control, price value, emotional value and social value have considerable influence on consumers' intention to buy ginseng products, and the influence of perceived value is significantly greater than the three factors of planned action theory. Moreover, the functional value has little influence on consumers' intention to buy ginseng products.

Objective: The purpose of this paper is to introduce a task complexity model combining task design aspects and complexity dimensions and to explain an approach to identifying and organizing task complexity factors based on the model. Background: Task complexity is a critical concept in describing and predicting human performance in complex systems such as nuclear power plants(NPPs). In order to understand the nature of task complexity, task complexity factors need to be identified and organized in a systematic manner. Although several methods have been suggested for identifying and organizing task complexity factors, it is rare to find an analytical approach based on a theoretically sound model. Method: This study regarded a task as a system to be designed. Three levels of design ion, which are functional, behavioral, and structural level of a task, characterize the design aspects of a task. The behavioral aspect is further classified into five cognitive processing activity types(information collection, information analysis, decision and action selection, action implementation, and action feedback). The complexity dimensions describe a task complexity from different perspectives that are size, variety, and order/organization. Combining the design aspects and complexity dimensions of a task, we developed a model from which meaningful task complexity factors can be identified and organized in an analytic way. Results: A model consisting of two facets, each of which is respectively concerned with design aspects and complexity dimensions, were proposed. Additionally, twenty-one task complexity factors were identified and organized based on the model. Conclusion: The model and approach introduced in this paper can be effectively used for examining human performance and human-system interface design issues in NPPs. Application: The model and approach introduced in this paper could be used for several human factors problems, including task allocation and design of information aiding, in NPPs and extended to other types of complex systems such as air traffic control systems as well.

Objectives : Alteration of hippocampus was demonstrated in the maternal social separation(MSS) pups, separated from dams on postnatal day(pnd) 14 and placed alone. Therefore, to understand the molecular events involved in the MSS, we have initiated a search for gene profiles that are up or down-regulated in the hippocampus of MSS pups. Methods : Analysis of cDNA microarray was performed by using total RNA extracted from the hippocampus of control and MSS pups on pnd 17. Also, passive-avoidance test was demonstrated on pnd 35. Results : Up-regulation of Nedd4a was observed in the hippocampus of MSS pups. Also, MSS rats showed less elongation of latency in passive avoidance test. Conclusion : We suggest that environmental effects of MSS may be altered the neural and/or glial differentiation and synapse formation-related genes which may lead cognitive alterations in MSS rats.

This study is to examine the effect of swimming exercise on the expression of c-fos, c-jun protein in rat hippocampus. 4-weeks aged rats and 16-weeks aged rats were used in experimental materials. All of two groups were classified into control and swimming exercise group. Swimming exercise was practiced for an hour a day. The results were got as follows after practical application in 1 day, 3days, 7 days. The expression of c-fos, c-jun protein was increased in all of the two experimental groups significantly in 1 day, 3days, 7 days. It was increased gradually in order of after 1 day, 3days, 7 days. There seems to be the effect of swimming exercise increasing the expression of c-fos, c-jun protein in hippocampus. Therefore swimming exercise can improve cognitive function such as learning and memory and prevent through activating immediate - early gene by swimming exercise. And it seems to have the positive effect on growth and recovery of nerve.

The purpose of this study was to examine the effects of physical activity using visual stimulation smart devices on the athletic performance and attention - The conclusion is as follows. The physical activity using visual stimulation smart device was applied to the infant. The pre - and post - experiment results showed that the infants of the experimental group were higher than those of the control group. Specifically, the ability of the infant to participate in physical activity using the visual stimulation smart device was improved by sit-up bending and centering ability. Also, physical activity using visual stimulation smart device helped to improve attention of infants. In other words, it was confirmed that information and communication technology (ICT) and physical activity affect both physical and cognitive development of infants. Therefore, in order to improve the athletic ability and concentration of children more effectively, it is possible to maximize the educational effect by teaching the contents using various contents that can motivate the infant rather than the same teaching method.

This research extends a general theory of human cognition to an applied domain of piloting skills. We examined how fast and accurately pilots achieve and maintain situation awareness in flight by measuring their consistency judgment between a written statement describing a flight situation and a cockpit display showing a current state of an aircraft. The goal of this research is to determine whether situation awareness is influenced by expertise level as a Auction of two different kinds of flight situation variables. It was revealed that flight situation variables representing relations between flight elements had an effect on situation awareness. Working memory was found to play a critical role in integrating a variety of flight information form multiple sources. It was also revealed that flight situation variables representing the contents of flight elements had influence on situation awareness in flight. These results were explained in a theoretical framework of a construction-integration model to reveal the cognitive processes underlying situation awareness in flight.

Objectives : The purpose of this study was to compare two subtypes of attention-deficit hyperactivity disorder (ADHD) and controls in their attention using ADHD diagnostic system (ADS), a kind of continuous performance test. Methods : Subjects of this study were 8 children with ADHD-predominantly inattentive type, 28 children with ADHD-combined type and 20 control children. Ages ranged from 5 to 14 years. The Korean Educational Development Institute version of the Wechsler Intelligence Scale for Children (KEDI-WISC) and the ADS were administered to all subjects to provide measures of intelligence and attention. Results : Significant differences were found in the ADS variables for the three groups. When compared with controls, the ADHD-predominantly inattentive type children scored significantly higher on the omission error at middle stage and later stage and ADHD-combined type children scored significantly higher on the omission error and reaction time at later stage. When compared with the other two groups, the ADHD-combined type children scored significantly higher on the commission error at all three stages. Conclusion : Our results suggest that the two subtypes of ADHD have different features in attention deficit. And there was a possibility that commission error is available variable to show cognitive characteristics of ADHD-combined type than any other ADS variables. Further studies are needed to evaluate this finding.

Objectives: The purpose of this study is to evaluate the program theory of a lifestyle intervention program for the prevention and treatment of metabolic syndrome. Methods: The program evaluated is a tailored intervention for multiple health behavior associated with metabolic syndrome which is informed by theoretical constructs from the Intervention Mapping and Transtheoretical model. The program components include one-to-one health counseling, a self-management handbook, and a health diary. To evaluate program impact theory we examined the logic of program goals and objectives, intervention methods and strategies, and the theoretical constructs of program materials through document review and matrix building. Results: This evaluation has found that the intervention program applied social cognitive theory constructs to design intervention methods and strategies in addition to the Transtheoretical model: self-monitoring for goal setting and monitoring skill, outcome expectation for the benefits of health behavior change, and interaction with environment for observational learning through modeling. While the intervention addresses multiple determinants and behaviors, it is limited to an individual level and lacks social and environmental approaches. Following the Transtheoretical framework, the contents of the intervention materials were developed utilizing consciousness raising as a main strategy for earlier stages of change, and counterconditioning and stimulus control for later stages of change. Conclusion: Program theory evaluation can be a process of enhancing program validity. It would also be necessary for providing basis for efficient program implementation. When comparisons of program theory between similar programs are possible, program theory and validity will be strengthened when comparisons of program theories between similar programs are possible.
