Non-verbal communication is important in human interaction. It provides a layer of information that complements the message being transmitted. This type of information is not limited to human speakers. In human-robot communication, increasing the animacy of the robotic agent-by using non-verbal cues-can aid the expression of abstract concepts such as emotions. Considering the physical limitations of artificial agents, robots can use light and movement to express equivalent emotional feedback. This study analyzes the effects of LED and motion animation of a spherical robot on the emotion being expressed by the robot. A within-subjects experiment was conducted at the University of Tsukuba where participants were asked to rate 28 video samples of a robot interacting with a person. The robot displayed different motions with and without light animations. The results indicated that adding LED animations changes the emotional impression of the robot for valence, arousal, and dominance dimensions. Furthermore, people associated various situations according to the robot's behavior. These stimuli can be used to modulate the intensity of the emotion being expressed and enhance the interaction experience. This paper facilitates the possibility of designing more affective robots in the future, using simple feedback.

Objectives: Although aggressive behavior in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) has previously shown correlations with hyperactivity/impulsivity, few studies have examined its association with inattention or the effect of working memory on aggressive behavior. This study aimed to assess the relationship between inattention and aggressive behavior and the effect of working memory on the relationship between inattention and aggressive behavior in children and adolescents with ADHD. Methods: Thirty-one children and 26 adolescents with ADHD were retrospectively investigated. The subjects completed the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV), the Korean Child Behavior Checklist (K-CBCL), and the Korean Children's Depression Inventory (CDI). Results: Inattention was positively correlated with aggressive behavior in children and adolescents with ADHD and working memory showed an insignificant correlation. However, working memory had a significant moderating effect on aggressive behavior by interacting with inattention. The moderating effect of working memory manifested when the working memory index score on the K-WISC-IV was 73.5 points or higher, and it had a significant effect on aggressive behavior. Conclusion: This study shows that the severity of inattention and hyperactivity/impulsivity should be addressed to provide appropriate treatment to children and adolescents with ADHD who exhibit aggressive behavior.

The purpose of this research is to scrutinize what are characteristics of client-identified significant events and interactional process in Gestalt therapy using the therapeutic media. The subjects of the study were 4 participants. To this purpose, a audio-taped session and a intensive interview were conducted to examine. The collected data for this study were analyzed by Comprehensive Process Analysis. The audio-taped session and interview data were first transcribed and then analyzed for client-identified significant events. A total of 74 pairs of conversations were analyzed to derive the interactional process within the significant event case. In conclusion, it was found that the interactional process of significant events in the Gestalt therapy contributed to the change of the client by interacting with the therapeutic media. 5 major themes of interaction with the therapeutic madia appeared. The 5 major themes are allowance, identification, recognition, acceptance and prospective. Finally, the significance and limitations of the study were clarified and suggested for further study.

Objective : Peroxisome proliferator-activated receptor (PPAR)-gamma, a transcription factor in adipocyte differentiation, has important effects on insulin sensitivity, atherosclerosis, endothelial cell function and inflammation. Through these effects, PPAR-gamma2 might be involved with type 2 diabetes and vascular disease, including diabetic complications. Recently, it has been reported that the C161T polymorphism in the exon 6 of PPAR-gamma is associated with type 2 diabetes interacting with uncoupling protein 2 (UCP2) gene, and is associated with acute myocardial infarction. We studied the association of this polymorphism with type 2 diabetes and its complications, such as retinopathy, ischemic stroke, nephropathy and neuropathy in Korean non-diabetic and type 2 diabetic populations. Methods : Three hundred and thirty eight type 2 diabetic patients (retinopathy: 64, ischemic stroke: 67, nephropathy: 39 and neuropathy: 76) and 152 healthy matched control subjects were evaluated. The PPAR-gamma C161T polymorphism was analyzed by PCR-RFLP. Results : PPAR-gamma C161T genotype and allele frequency did not show significant differences between type 2 diabetic patients and healthy controls (T allele: 17.0 vs. 14.5, OR= 1.21, P=0.3188). In the analysis for diabetic complications, T allele in diabetic nephropathy was significantly higher than controls (P=0.0358). T allele in the ischemic stroke patients was also higher than healthy controls, although it had no significance (P=0.1375). Conclusions : These results suggest that the C161T polymorphism of the PPAR-gamma gene might be associated with diabetic nephropathy in type 2 diabetes.

Robots evolve from tools to information media since they generates information by interacting with human. As studies on robot-aided education are still in a starting phase, attempts need to be made to use robots for educational purposes and to investigate the effects of the use. It was showed that robot-aided learning was friendlier than other media assisted learning, and especially effective for motivating children. We developed the prototype robot Jenny that can help teachers as a educational media in class(i.e. as a T.A. robot, it can present robot contents on its chest to screen and explain about it when teacher asks). is a schoolmate for 5th or 6th grade children or an elder schoolmate for the rest. We performed the field trial at an elementary school. We carried out 9 classes for three subjects(english, korean, music) with -students in $4th{\sim}5th$ grade. They thought Jenny who was 13 years old as an elder schoolmate in 6th grade. Also, a significant difference was found in the interest and concentration of experimental groups from controlled groups.

Purpose: This study was done to examine the correlations between personality type and job satisfaction of nurses. Methods: Subjects included three hundred twelve nurses ages from 21 to 55. The Myers-Briggs Type Indicator(MBTI) was administered to determine the personality types of the nurses(n=312). A job satisfaction survey including a demographic and career questionnaire was also used. Data were analyzed using ANOVA. Results: The mean score fur job satisfaction was 113.68 out of 205. The result showed that there was no statistically significant correlation between job satisfaction and information gathering functions, S: Sensing, N: Intuition (t=.667, p=.499), T; Thinking, F; Feeling (t=.822, p=.412). The results, however, indicated that style for gaining energy(I: Introversion, E: Extroversion)(t=2.008, p=.046) and life dealing style(J : Judgement, P : Perception)(t=2.290, p=.023) were significantly correlated with job satisfaction. The extrovert focuses on the outside and get energy through interacting with people and doing things. Judgement type is described as organized, decisive, and orderly. Conclusion: Nurses in the extrovert and judgement types were more satisfied with their Jobs than those in the introvert and perceptive type. Other results support that educational level, marital status, job characteristics, clinical experiences, motivation for nursing, and night duty were correlated with job satisfaction.

In this paper, we address the challenging computer vision problem of obtaining a reliable facial expression analysis from a naturally interacting person. We propose a system that combines a 3D generic face model, 3D head tracking, and 2D tracker to track facial landmarks and recognize expressions. First, we extract facial landmarks from a neutral frontal face, and then we deform a 3D generic face to fit the input face. Next, we use our real-time 3D head tracking module to track a person's head in 3D and predict facial landmark positions in 2D using the projection from the updated 3D face model. Finally, we use tracked 2D landmarks to update the 3D landmarks. This integrated tracking loop enables efficient tracking of the non-rigid parts of a face in the presence of large 3D head motion. We conducted experiments for facial expression recognition using both framebased and sequence-based approaches. Our method provides a 75.9% recognition rate in 8 subjects with 7 key expressions. Our approach provides a considerable step forward toward new applications including human-computer interactions, behavioral science, robotics, and game applications.

The purpose of this study is to investigate the difference in advertising effect of visual rhetoric type of Facebook ads depending on the user sensitivity and level of empathy. The experiment was designed as a between-subjects factorial design (visual rhetoric type) × 2 (brand sensitivity) × 2 (level of empathic understanding). The results of the experiment performed to analyze the strategies of Facebook ads for ads effectiveness can be summarized as follows: a three-way interaction effect for persuasive effects was found among the type of visual rhetoric, brand sensitivity, and empathic understanding for both types of visual rhetoric. Breaking down it by type of rhetoric, no interacting effect was observed between brand sensitivity and empathic understanding levels for the visual simile ads in most of the dependent variables. For the visual metaphor ads, however, the brand sensitivity and empathic understanding levels were found to have interaction effect in all dependent variables.

The purpose of this study was to analyze pre-service teachers' perceptions and change on the images about young children. The subjects of this study were 31 students in the early childhood department at a university. It was a longitudinal study conducted for four years. The data regarding the images that students had about young children were collected by having them answer a question. The question was "Young children are... Because of..." Subjects were asked to answer that question when they were freshmen and then, to answer the same question when they were seniors in order to see the change. A content analysis and frequency were conducted. The study of the results could be summarized as follows. Firstly, from their first year to senior year, the images that pre-service teachers perceived such as, vibrant active beings and beings with various characteristics" did not change. However, the images such as "being who was capable of interacting with environments" had changed. And the new image which viewed a child as a being who should be respected emerged. Secondly, the factors that influenced the image changes were based on the experience of working as assistant teachers at an early childhood setting, and practicum. Therefore, a systematic work on assistant teachers should be done and a concept about child-center education should be built.
