This study investigates the physical properties and manufacturing method of shape memory fabric for emotional garment made by polypropylene. For this purpose, polypropylene(PP) POY and SDY were texturized using low temperature and constant length heat treatment texturing technologies, respectively. The shape memory fabrics made using these texturized PP yarns were woven with two kinds of PET and PTT shape memory yarns on the air-jet loom and the various physical properties of four kinds of shape memory fabrics were measured and discussed. The tenacity and breaking strain of PP texturized yarns treated by low temperature and constant length heat treatment showed high weaving efficiency and the wet thermal shrinkage of PP textured yarns was shown less than 1.5%, dry thermal shrinkage was ranged between 3% and 5%, which means thermal stability compared to the PTT textured yarn with high thermal shrinkage, 5~8%. The shape memory characteristics of PP shape memory fabrics measured by Toray method showed five grade as same value as PTT shape memory fabric. The heat keeping property of the PP shape memory fabric showed 56% higher value than that of PTT shape memory fabric. The water repellency of PP shape memory fabric measured by spray method showed five grade as same value as PTT shape memory fabric treated with water repellent agent. Especially, shape memory properties of PP shape memory fabric measured by 3-D image and camera measurement methods showed similar characteristics to the PTT shape memory fabric.

Recent studies on emotion as memory,and effects of emotion on memory were reviewied. The main issues discussed were : memory of emotional events,relation between implicit memory and emotion, and the effect of emotion on autobigraphical memory. The theoretical possibility and implications that emotion is not stored as some lower level node information in semantic network but as some higher level and inclusive information were descussed.

In this study, memory for emotional words was compared between extraverts and introverts, employing signal detection analysis to distinguish differences in discriminative memory and response bias. Subjects were presented with a study list of emotional words in an encoding session, followed by a recognition session. Effects of task difficulty were examined by varying the nature of the encoding task and the intervals between study and test. For an easy task, with a retention interval of 5 minutes (Study I), introverts exhibited better memory (i.e., higher d') than extraverts, particularly for low-frequency words, and response biases did not differ between these two groups. For a difficult task, with a one-month retention period (Study II), performance was poor overall, and only high-frequency words were remembered; also extraverts adopted a more liberal criterion for 'old' responses (i.e., more hits and more false alarms) for positive emotional-valence words. These results suggest that as task difficulty drives down performance, effects of internal control processes become more apparent, revealing differences in response biases for positive words between extraverts and introverts. These results show that extraversion can distort memory performance for words, depending on their emotional valence.

사람들은 같은 상황에서도 감정적 경험에 따라 다르게 반응한다. 상황에 따른 감정을 나타내고자 하는 인공감정에 대한 많은 연구가 이루어지고 있지만, 기존의 인공감정들은 같은 상황에서 같은 반응을 하도록 설계되었다. 하지만 현재 느끼는 감정이 과거에 경험했던 감정적 경험에 영향을 받기 때문에 같은 상황에서 다른 반응을 유발한다. 본 논문은 감정적 경험을 기억해서 현재의 감정에 영향을 주는 메커니즘을 제안한다. 감정적 기억은 연관성이 있는 기억끼리 연상되는데 이 과정은 SOM의 연관성이 있는 것끼리 뭉치면서 스스로 학습하는 자기조직화의 특성과 유사하다. 이러한 유사점을 이응해서 감정적 경험을 기억하는 과정을 설계했다. 제안된 방법을 가위바위보로 승자가 패자를 뿅망치로 때리는 게임에 적용하여 같은 상황에서도 감정적 경험에 의해 다르게 반응하는 모습을 나타낸다. 게임을 진행하면서 가위바위보 승패에 따라 분노, 공포, 쾌락 등의 감정을 경험하게 되는데 이러한 감정적 경험이 SOM을 이용한 감정기억메커니즘에 의해 기억된다. 그 결과 감정적 경험에 대한 기억이 가위바위보에 이겼을 때의 느끼는 감정에 영향을 주어 현재 느끼는 감정 상태에 따라 뿅망치 파워가 달라지도록 했다.

Objective: The aim of this study is to investigate the quantitative effects of various emotions and retention periods on the color vividness of visual memory. Background: Although numerous studies have focused on the effects of emotions on memory such as visual detail and vividness of emotional events compared to neutral events, the relationship between emotion and visual memory is ambiguous yet. Furthermore, there were few studies on the effect of emotion on vividness of visual memory. Method: A total of 68 subjects were participated in serial experiments proceed on online and the experiments had two phases: recognition phase and reproduction phase. The 15 photographs were used as visual stimuli and all experiments were conducted over the internet(experiment website) and the results were collected on the web database. Results: The retention period, sleep-arousal emotion and subjective saturation of visual stimuli had a significant effect on the color vividness of visual memory. Conclusion: The results suggested that the color of visual stimulus might be more vividly remembered when it is arousing, the subjective saturation is higher and the retention period is longer. Application: The findings of this study may help clarify the relationship between human emotions and visual memory.

This study identified the impact of augmented reality advertising on attitude toward advertising and memory according to the type of presence and flow level. The presence (cognitive, emotional, media) and flow level (high vs. low) of the augmented reality(AR) advertising were set as independent variables and analyzed by Two-Way MANOVA. As a result of the research, first, the augmented reality advertising attitude was positive when the emotional presence and flow level were high. Second, when the flow level is high, the ARM such as product attribute information increases, but when the flow level is low, the evaluation-oriented GRM increases. Third, emotional presence increases GRM when the flow level is high, but ARM increases when the flow level is low. Fourth, the memory effect was low regardless of the flow level. In the future research, it would be desirable to produce augmented reality advertisements through virtual brands in the generalization of research.

This study was performed to phenomenologically look into residential behaviors from the standpoint of human housing environment experiences, rather than physical environment, aiming to examine the emotional implication of housing environment by finding human mental motives included in memorable adolescent experiences into housing environment. In this study, an analysis on an environment life story was used to describe both the behaviors and spaces of significantly memorable experiences into housing environment. In addition, this study was carried out by analysing the emotional implication of descriptions selected from respondents' answers. A questionnaire survey was performed by questioning the students of D university about their significantly memorable adolescent experience in housing environment from the 4th to 15th of June 2007. Statistic date was analysed using the SPSS 14.0 Program.

It is known that gamma-band activity (GBA) and phase synchrony (GBPS) are induced by emotional visual stimuli. However, the characteristics of GBA and GBPS according to different emotional states have not been identified. The purpose of this study is to investigate the changes in gamma-band neuronal synchronization induced by positive and negative emotional visual stimuli using electroencephalograms (EEGs). Thirteen healthy male subjects have participated in the experiment. The induced spectral power in gamma-band was the highest for negative stimuli, and the lowest for neutral stimuli in 300-2,000 ms after the stimulus onset. The inter-regional phase synchronization in gamma-band was increased in 500-2,000 ms, mainly between the bilateral frontal regions and the parieto-occipital regions. Larger number of significant connections were found by negative stimuli compared to positive ones. Judging from temporal and spatial characteristics of the gamma-band activity and phase synchrony increases, the results may imply that affective visual stimuli cause stronger memory encoding than non-emotional stimuli, and this effect is more significant for negative emotional stimuli than positive ones.

The purpose of this study is to investigate the prevalence of children's somatic symptoms and the relationships among parent and child variables such as parenting attitude, children's anxiety, emotional expressiveness and somatic symptoms. The subjects were 523 6th grade students in four elementary schools located in Seoul, Busan and Daejeon. All subjects were tested with the Korean version of Children's Somatization Inventory (K-CSI), Parental Rearing Attitude Inventory, State-Trait Anxiety for Children (STAIC), and The Emotional Expressiveness Questionnaire. The collected data were analyzed by the frequency and percentage of somatic symptoms the children had experienced during the last 2 weeks; Pearson's correlation and multiple regression were used for the selected data of 10 somatic symptoms which were experienced by over 10% of the children. The results are summarized as follows: First, abdominal pain, headache, dizziness, and memory failure, in that order, were experienced in over 20% of the children. Second, children's somatic symptoms had significant relations with mothers' and fathers' loving-denial attitudes and their anxiety and emotional expressiveness. Third, children's somatic symptoms were influenced by their anxiety and emotional expressiveness, but not by parenting attitude.

The interaction of emotion is an important factor in Human-Robot Interaction(HRI). This requires a contextual appraisal of emotion extracting the emotional information according to the events happened from past to present. In this paper an emotion appraisal system based on the cognitive context is presented. Firstly, a conventional emotion appraisal model is simplified to model a contextual emotion appraisal which defines the types of emotion appraisal, the target of the emotion induced from analyzing emotional verbs, and the transition of emotions in the context. We employ a language based cognitive system and its sentential memory and object descriptor to define the type and target of emotion and to evaluate the emotion varying with the process of time with the a priori emotional evaluation of targets. In a experimentation, we simulate the proposed emotion appraisal system with a scenario and show the feasibility of the system to HRI.
