This study intended to empirically verify the effect of message framing, cognitive need for closure, and type of fashion products on purchasing attitude of PB fashion products in discount stores. The design consisted of three-mixed design of 2(POP(Point of Purchase)message framing: benefit message vs. loss message) ${\times}2$(cognitive need for closure: high vs. low) ${\times}2$(PB fashion product type: utilitarian vs. hedonic). Survey of this study was conducted on 330 men and women in 20~50's in Seoul and Gyeong-gi, and a total of 287 data were analyzed. Data were analyzed with SPSS 18.0 program, and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First, it was identified that the framing type of POP message of discount store, cognitive need for closure, and PB fashion product type had significant effect on preference and purchase intention. Secondly, it was identified that consumers with both high and low cognitive need for closure had high preference level and purchase intention when they encountered the benefit message framing than the loss message framing. Thirdly, the benefit message framing was more effective than the loss message framing for hedonic PB fashion products in discount stores, but utilitarian PB fashion products did not get affected by the message framing. Fourthly, it was identified that groups with both high and low cognitive need for closure preferred hedonic PB fashion products. Lastly, it was verified that benefit message framing POP advertisement on a group with high cognitive need for closure was effective for Hedonic PB fashion products in discount stores, and utilitarian PB fashion products showed no difference in purchase intention according to the POP message framing type and cognitive need for closure.

Purpose: Parkinson's disease (PD) has a high incidence of psychiatric comorbidity, specifically depression and anxiety. This study examined the effectiveness of group cognitive behavioral therapy (CBT) in treating depression and anxiety. Methods: The study included 42 participants, aged between 52 and 77 years, who were diagnosed with idiopathic Parkinson's disease (IPD) and reported suffering from depression and anxiety. Patients were attending a department of outpatient neurology at D University Schools of Medicine in B Metropolitan city. A structured telephone-administered cognitive behavioral therapy was conducted for eight weeks. A repeated measure ANOVA was used to analyze results at pretest, post-test, and four weeks follow up. Results: According to service method, there were significant differences between the two groups in depression, anxiety and stigma was significant difference between time (p<.05). Analysis of the interaction between time and service method revealed significant differences in depression and anxiety (p<.05). Conclusion: The results suggest that telephone-administered cognitive behavioral therapy may be effective and may provide opportunity to adapt to individual needs for treating depression and anxiety in patients with Parkinson's disease.

본 연구는 지구과학 탐구활동에서 그룹의 상호작용 양식에 따라 학생들의 반성적 탐구는 어떤 특징을 보이는지를 알아보고, 수업의 3가지 맥락들은 반성적 탐구활동에서 어떻게 관련되는지를 알아봄으로써 학생들의 반성적 탐구의 실제를 이해하고 반성적 탐구를 촉진하기 위한 탐구활동 수업의 시사점을 얻고자 하였다. 이를 위해 고등학교 1학년 1개 학급을 선정해서 본 연구에서 개발한 반성적 탐구활동수업을 실시하고 수업을 녹화 전사해서 언어행동분석틀과 수업상황의 3가지 맥락으로 분석하였다. 사전 검사를 통해 알아낸 학습자 특성을 기초로 그룹을 나누어 수업을 실시하였으며 면담을 실시하여 수업분석에 참고하였다. 반성적 탐구활동수업에서 그룹 상호작용양식에 따른 반성적 탐구의 차이는 조화적 상호작용양식을 보이는 그룹에서는 전개와 정리단계에서 자료와 과제맥락이 연결된 반성적 탐구가 자주 나타난 반면, 대립적 상호작용양식 그룹에서는 자료맥락과 연결된 반성적 탐구가 아주 드물고 반성적 탐구척도 값도 2 배 이상 낮게 나타났다. 즉 조화적 그룹이 양적으로 더 많은 반성적 탐구진술을 했으며 자료맥락과 과제맥락을 연결하는 더 의미 있는 반성적 탐구를 했다는 것을 알 수 있었다. 탐구능력과 인지양식에 있어서 이질그룹은 정의적 측면에서 대립적 상호작용양식을 보여 반성적 탐구에 가장 부정적인 영향을 끼쳤고, 인지양식과 탐구능력 모두에서 동질그룹은 조화적 상호작용양식을 보여 반성적 탐구에 긍정적인 영향을 주었다는 것을 알 수 있었다. 이러한 결과로부터 반성적 탐구활동을 촉진시키기 위한 그룹조직의 시사점을 얻을 수 있었다.

Background: Performing cognitive tasks and muscular fatigue have been shown to increase muscle activity of the lower extremity during quiet standing. A common intervention to reduce muscular fatigue is to provide a softer shoe-surface interface. However, little is known regarding how muscle activity is affected by softer shoe-surface interfaces during static standing. The purpose of this study was to assess lower extremity muscular activity during erect standing on three different standing surfaces, before and after an acute workload and during cognitive tasks. Methods: Surface electromyography was collected on ankle dorsiflexors and plantarflexors, and knee flexors and extensors of fifteen male participants. Dependent electromyography variables of mean, peak, root mean square, and cocontraction index were calculated and analyzed with a $2{\times}2{\times}3$ within-subject repeated measures analysis of variance. Results: Pre-workload muscle activity did not differ between surfaces and cognitive task conditions. However, greater muscle activity during post-workload balance assessment was found, specifically during the cognitive task. Cognitive task errors did not differ between surface and workload. Conclusions: The cognitive task after workload increased lower extremity muscular activity compared to quite standing, irrespective of the surface condition, suggesting an increased demand was placed on the postural control system as the result of both fatigue and cognitive task.

Mental workload has a improtant place in modern work environment such as human-computer interaction. Designing man-machine system requires knowledge and evaluation of the human cognitive process which controls information flow during our works. Many studies estimate reaction time as a index of menatal workload. This paper investigates what reflacts the workload of human information handling when the informations grow its degree. Experiment result introuce the memory time that explain the information-load more sensitive than react time. And react time shows learning effect but memory time does'nt show that effect So it can be concluded that cognitive learning or work schema needs more time to achieve dexterity than motor skill.

The purpose of this study was to investigate the personal traits of children's characteristics as well as those of mothers' on the children's maladjustment behaviors. The study subjects were 345 preschooler-mother pairs. Results revealed that boys exhibited more maladjustment behaviors than girls, as expected. The results of a three way ANOVA analyses indicated that the multiple interactive factors of the children's temperament, cognitive outcomes, and parenting attitudes significantly affected the children's maladjustment behaviors. This trend was only representative across the sample of boys. In this study, the interaction effects of negative parenting attitudes and the children's lower levels of cognitive development on the children's maladjustment capacity were accentuated among boys with temperamental vulnerability.

Emotion interaction between human and robot is an important element for natural interaction especially for service robot. We propose a hybrid emotion generation architecture and detailed design of reactive process in the architecture based on insight about human emotion system. Reactive emotion generation is to increase task performance and believability of the service robot. Experiment result shows that it seems possible for the reactive process to function for those purposes, and reciprocal interaction between different layers is important for proper functioning of robot's emotion generation system.

Purpose: The purpose of this study was to explore the concept of Mother-Child Interaction (MCI). Methods: The concept analysis method described by Walker & Avant (2005) was used. Results: The attributes of MCI were as follows; 1) MCI involves positive or negative affective and verbal communication. 2) MCI involves mother, child, and dyadic activity. 3) MCI involves sensitivity, responsiveness, and child developmental stimulation. 4) MCI is reciprocal, goal-oriented partnership process. The antecedents of MCI are need for goal attainment, relationship, and child development (cognitive, physical, emotional, and social). The consequences of MCI are goal attainment, promotion of mother-child relationship, and promotion of child development. Conclusion: MCI is a reciprocal, goal-oriented partnership process and is an important concept in child development and health. Appropriate instruments to operationalize the concept need to be developed.
