When visual and auditory information is presented simultaneously, we perceive visual information dominantly over auditory information. This effect is called the visual dominance effect. This study was to examine the influence of semantic congruence of visual and auditory information on the visual dominance effect. The semantic congruence of visual and auditory information was manipulated. The results showed that the visual dominance effect obtained in error rates was not modulated by semantic congruence, whereas the effect in RT was. It is suggested that this modulation of the influence of semantic congruence on the visual dominance effect would be due to the task type.

Fuzzy cognitive map(FCM) has long been used as an effective way of constructing the human's decision making process explicitly. By taking advantage of this feature, FCM has been extensively used in providing what-if solutions to a wide variety of business decision making problems. In contrast, the goal-seeking analysis mechanism by using the FCM is rarely observed in literature, which remains a research void in the fields of FCM. In this sense, this study proposes a new type of the FCM-based goal-seeking analysis which is based on utilizing the genetic algorithm. Its main recipe lies in the fact that the what-if analysis as well as goal-seeking analysis are enabled very effectively by incorporating the genetic algorithm into the FCM-driven inference process. To prove the empirical validity of the proposed approach, valid questionnaires were gathered from a number of experts on software sales, and analyzed statistically. Results showed that the proposed approach is robust and significant.

The interest and expenditure for children is increasing than in the past because the number of nuclear family is growing, the children's space is configured independently in most homes from infancy, therefore, the market of children's furniture is expanding in spite of the reduction in the population of children. There are not many products considering age, gender, and play behavior in children's furniture market in Korea. The bed, desk, chair, and closet for children under 2 years hold a large majority of children's furniture, there are not a lot of preschool children's furniture for the children aged 4 to 7. As the children aged 4 to 7 experience physical, emotional, and cognitive growth at the same time, the space configuration and furniture choice for these children is educationally very important. Therefore, in this study, we present the importance and necessity of playable furniture to promote the physical, social, emotional, linguistic, and cognitive development of the children aged 4 to 7 among preschool children. We found the concept and basic condition of playable furniture to collect the base data for developing playable furniture and provided the basic data for the development of an ideal playable furniture by comparing and analyzing the cases of 157 items of 14 domestic playable furniture companies and 365 items of 30 overseas in aspect of play functions, forms, materials and colors.

Object : This study was designed to asses the protective effects of Kunneo tang on cognitive decline of the patients with early DAT. Method : Before administered with Kunneotang, 16 patients with early DAT were measured by auditory ERP, MMSE-K and K-DRS. During 12 months the patients with early DAT were administered with Kunneotang. After 12months the patients were measured by the same examinations again. Result : 1. The total score of MMSE-K decreased but it was not significant. 2. The total score of K-DRS increased but it was not significant. Among the five criteria(attention, memory, initiation/perseveration, construction, conceptualization), Initiation/perseveration score signifcantly decreased and there were no significant differences in the other scores. But, memory mean score had a tendency to increase. 3. The latency of ERP P300 component increased but it was not significant and the amplitude of ERP P300 component showed the significant difference. Conclusion : The results suggest that Kunneotang may have protective effects on cognitive decline in the patients with early DAT.

This study set off to explore the effect of interactive videos on developing mind mappings skills required for the common first-joint year students at Umm Al-Qura University. Towards this end, the experimental research design of a quasi-experimental of two experimental groups was adopted. The research tools consisted of an achievement test of the cognitive aspects of mind mapping skills and a product evaluation form of mind mapping skills. Results showed statistically significant differences at the significance level (α 0.05) between the mean scores of the two experimental groups who studied the educational video regardless of the type of video in the pre-post cognitive test of the mind mapping skills and the form of product evaluation. Besides, there are statistically significant differences at the significance level (0.05≥α) between the mean scores of the first experimental group who studied the conventional educational video and the mean scores of the second experimental group who studied the interactive educational video. This significant difference was in the posttest of mind mapping skills and in favor of the group who studied the interactive educational video. Nevertheless, there were no statistically significant differences at the significance level (0.05≥α) between the mean scores of the first and second experimental groups in the post-application of the product evaluation form of mind mapping skills. The researcher recommended using the interactive video in teaching courses to common first-year students. It also recommends organizing courses for the faculty members to train them on using interactive videos in their teaching.

Using Bernd H. Schmitt's experiential modules, this study investigated the effect of shopping value on recognizing the importance of customer experience. A survey was conducted with 400 adults aged in their 20s to 50s. To analyze the data, factor analysis, a reliability test, cluster analysis, and ANOVA were conducted. The results were as follows. First, the shopping values exhibited by sportswear consumers were a utilitarian shopping value and a hedonic shopping value. Through these, consumers were classified into four groups: a shopping value-oriented group, a utilitarian shopping value group, a shopping value-unconcern group, and a hedonic shopping value group. Second, the customer experience consisted of five factors: sensory experience, emotional experience, cognitive experience, behavioral experience, and relational experience. Third, a significant difference was observed in customers' perceived experiences according to shopping value type. In the shopping value-oriented group, all customer experiences were generally considered important, followed by the hedonic shopping value group and the shopping value-unconcern group, with the utilitarian shopping value group least likely to perceive customer experiences as important. In addition, cognitive and emotional experiences were rated highest among the five experiences, indicating that these were the most important store experiences among the various customer experience components.

Objective：This study is designed to get clinical guidelines for management of children with TBI by examining neuropsychiatric sequelae of TBI, determining whether the severity of TBI, type of treatment, and enviornmental factors are related to those sequelae, and defining the adequacy of public psychological tests as evaluating tools for them. Method：This is chart review of 47 children, aged 5 to 14 years, referred to a psychiatric outpatient clinic for neuropsychiatric evaluation at least 6 months after TBI. Data on the initial GCS score, associated injury, treatment type, and duration of hospital stay are obtained from medical records. EEG, MRI, intelligent test, and several psychological tests are administrated at the point of assessment. Results：1) Cognitive symptoms outnumber externalizing behavioral, emotional, and somatic symptoms, with no significant differences of frequencies of those 4 categorical symptoms between mild injury group and moderate to severe group. 2) Children treated with non-surgical method(p<0.01) complain more cognitive symptoms than the others. 3) Behavioral symptoms are related to younger age(p<0.05), and to anticonvulsant medication(p<0.05). 4) Children with associated injury complain emotional symptoms more frequently(p<0.05). 5) More somatic symptoms are presented by children with no medication(p<0.05), and with higher I.Q(p<0.05). 6) Low I.Q is correlated to low GCS score (p<0.05). Cognitive impairment is confirmed in 25 in 42 children complaining cognitive symptoms though I.Q test and BGT, whose hospital stay is longer than the others(p<0.05). 7) emotional disturbance is confirmed in 22 in 25 children showing emotional problems through psychological tests, who complain cognitive symptoms more frequently(p<0.05). Conclusion：This findings suggest that even mild TBI children need to be followed-up and treated as complaining neuropsychiatric symptoms over 6 months after injury, and shorter hospital stay is recommended for cognitive and emotional status of children, and for better evaluation of neuropsychiatric sequelae of TBI, more specific tests should be included in neuropsychological test tools.
