This study predicted consumer approach/avoidance behavior through consumer emotional experiences and examined the moderating effect of perceived surprises in the context of digital signage in store environments. A self-administered questionnaire consisted of consumer emotional experience (e.g., pleasure, arousal, and dominance), approach-avoidance behavior and perceived surprise by digital signage. A total of 278 usable responses were obtained from consumers who experienced digital signage at fashion retail stores. The findings support the Mehrabian-Russell model in the context of digital signage. Approach behavior was predicted by pleasure and arousal emotional experience, while avoidance behavior was predicted by dominance. The moderating effect of perceived surprise was also indicated in the effect of emotional experience on approach or avoidance behavior. In the high level of perceived surprise, pleasure and arousal had significant effects on approach behavior, whereas dominance had significant effect on avoidance behavior. This study discussed theoretical and managerial implications for creating emotional experiences and developing strategic store management by utilizing new digital technology within the fashion retail environments.

In order to navigate the mobile robots safely in unknown environments, many researches have been studied to devise navigational algorithms for the mobile robots. In this paper, we propose a navigational algorithm that consists of an obstacle-avoidance behavior module, a goal-approach behavior module and a radial basis function network(RBFN) supervisor. In the obstacle-avoidance behavior module and goal-approach behavior module, the fuzzy-artificial immune networks are used to select a proper steering angle which makes the autonomous mobile robot(AMR) avoid obstacles and approach the given goal. The RBFN supervisor is employed to combine the obstacle-avoidance behavior and goal-approach behavior for reliable and smooth motion. The outputs of the RBFN are proper combinational weights for the behavior modules and velocity to steer the AMR appropriately. Some simulations and experiments have been conducted to confirm the validity of the proposed navigational algorithm.

현재 터치스크린은 핸드폰, 태블릿 PC 등 다양한 디바이스에 활용되고 있으며, 사람들은 터치스크린을 통해 다양한 동작과 시각적 경험을 하게 되었다. 본 연구에서는 터치스크린이 제공하는 동작, 시각적 경험이 기존 행동-태도의 연합으로 인해 사람들에게 어떤 영향을 미칠 수 있을지 알아보고자 하였다. 선행 연구들은 특정 행동이 사람들의 태도에 영향을 미친다고 주장하였고, 특히 접근-회피 행동은 다양한 방면에서 사람들이 사회적, 개인적으로 기존에 가지고 있던 태도에 영향을 주는 것으로 알려져 있다. 터치스크린에서의 동작은 접근-회피 경험을 가능하게 하므로 이 행동이 사람들의 태도에 어떤 영향을 미치는지 살펴볼 필요가 있다. 실험1에서는 터치스크린에서의 드래그 동작과 접근-회피 행동을 연합시킨 후, 제품에 대한 선호도와 구매의향을 살펴보았다. 그 결과, 접근 드래그를 했던 제품이 회피 드래그를 했던 제품보다 선호도와 구매의향 모두 높은 것으로 나타났다. 실험2에서는 행동을 배제한 접근-회피의 시각적 경험만을 제공하였을 때도 동일한 효과가 발생하는지 살펴보고자 하였다. 그 결과, 시각적으로 접근했던 제품이 회피했던 제품보다 선호도와 구매의향 모두 동일하게 높은 것으로 드러났다. 터치스크린에서의 팔의 움직임(실험1)과 접근-회피 경험의 지각(실험2)이 사람들의 제품에 대한 태도에 영향을 준다는 것을 알 수 있었다. 이는 모바일 혹은 온라인 쇼핑 상황에서 터치스크린 인터페이스 디자인 설계에 사람들의 행동과 지각이 중요하게 고려되어야 할 요소임을 제시한다.

팬데믹으로 인해 생활의 중심이 집으로 이동함에 따라 집을 다양한 활동에 최적화된 공간으로 만들어줄 수 있는 가정용 로봇의 개발이 활발하다. 이 연구는 로봇이 작업을 수행하는 상황에 따라 피드백을 하기 위한 접근 또는 회피 움직임이 사용자 경험에 미치는 효과를 확인하고자 하였다. 작업 수행 상황과 움직임 조건에 따라 6가지 시나리오를 구성하여, 각 조건에 따른 호감도, 인지된 지능, 친밀감, 부정적 태도, 행동 예측가능성을 측정하였다. 실험 결과, 작업 수행 상황에서는 인지된 지능과 친밀감, 행동 예측가능성에서 주효과가 나타났고, 움직임 조건에서는 호감도, 인지된 지능, 친밀감에서 주효과가 나타났다. 상호작용 효과는 호감도와 인지된 지능에서만 나타났다. 결론적으로 로봇의 움직임에도 접근-회피 경험을 적용할 수 있고, 회피에 따른 부정적 효과를 확인할 수 있었다.

This study explored the effects of self efficacy, classroom contextual characteristics and help-avoidance attitudes on academic help-seeking behavior. Participants were 210 4th grade students. Data were analyzed by Pearson's correlation coefficient and multiple regression analysis through the SPSSWIN 12.0. Results showed that students' self efficacy, perception of teacher behavior and goal orientations were positively related to help-seeking behaviors. Help-avoidance attitudes were negatively related to help-seeking behaviors. Cognitive efficacy and social-emotional efficacy facilitated help-seeking behaviors. Help-seeking behaviors were influenced by teacher's supportive help and expectation. Mastery goal orientations and performance-approach goal orientations promoted help-seeking behaviors but performance-avoidance goal orientations impeded help-seeking behaviors. Autonomous intention attitudes expedited help-seeking behaviors but intention based on ability diminished help-seeking behaviors.

The purpose of this study was to identify the patterns of coping with marital conflict and child-rearing stress among mothers of young children. The participants were 166 mothers of children who were between 3 years and 7 years of age, living in the North Kyongsang Province. Paired t-test, ANOVA, Scheffe' test, Pearson's correlation and partial correlation analyses were conducted for this study. The results of this study were as follows. (1) In those situations where the participants experienced marital conflict and child-rearing stress, they were more likely to use an avoidance coping strategy than an approach coping strategy. (2) Among the mothers who were experiencing marital conflict or child-rearing stress, the group that suffered a higher level of stress was more likely to employ an avoidance coping strategy. However, there were no differences in the approach coping behavior by the level of stress. (3) When the level of marital conflict and child-rearing stress were controlled, approach coping behavior with marital conflict was still moderately correlated with approach coping behavior with child-rearing stress.

This study explored the participant roles and the cross-sectional and longitudinal relationships between interpersonal behavior characteristics and bullying/victimization. The subjects were 4th and 5th grade children and instruments were the Participant Roles Scale, Self-Report Coping Scale, Teenage Inventory of Social Skills, and Social Anxiety/Avoidance. They were contacted again one year later. In the distribution of participant roles at Time 1, defender of the victim was highest, then outsider; at Time 2 outsider was the highest and then defender. There was a tendency of gender difference in distribution of participant roles only at Time 1. Males were more in the group of reinforcer; females were more in the group of defender and victim. There were high positive correlations among bully/reinforcer/assistant scores. In the concurrent view, children who used approach coping strategies and showed higher social skills were more likely to be defender. Children who had lower social skills and higher social anxiety and social avoidance were more likely to be victim. In the longitudinal view, children who had developed higher social skills were more likely to be defender. Children who had employed less approach coping strategies and had showed lower social skills and higher social avoidance were more likely to be victim.

The navigation algorithms enable autonomous mobile robots to reach given target points without collision against obstacles. To achieve safe navigations in unknown environments, this paper presents an effective navigation algorithm for the autonomous mobile robots with ultrasonic sensors. The proposed navigation algorithm consists of an obstacle-avoidance behavior, a target-reaching behavior and a fuzzy-based decision maker. In the obstacle-avoidance behavior and the target-reaching behavior, artificial immune networks are used to select a proper steering angle, make the autonomous mobile robot avoid obstacles and approach a given target point. The fuzzy-based decision maker combines the steering angles from the target-reaching behavior and the obstacle-avoidance behavior in order to steer the autonomous mobile robot appropriately. Simulational and experimental results show that the proposed navigation algorithm is very effective in unknown environments.

This study explored concurrent and prospective relationships of the coping strategies of 4th and 6th grade children in peer conflict focusing on bullying, victim, and prosocial behavior. Instruments were the Self-Report Coping Scale and the Peer Relations Questionnaire. Concurrent results of Study I showed children using more avoidance and fewer approach strategies were more likely to bullies or victims; and children using fewer avoidance and more approach coping strategies were more likely to be prosocial children. Externalizing best explained bullies and victims; seeking social support best explained prosocial children. Prospective results of Study II showed children using more externalizing and fewer problem solving were more likely to be bullies; and children employing internalizing and externalizing were more likely to be victims; and children using more seeking social support were more likely to be prosocial children. It was also found that externalizing at Time I best predicted bullies, internalizing best predicted victims, and seeking social support best predicted prosocial children.
