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.

Purpose: According to Lazarus & Folkman (1984), appraising a stressor as a threat is associated with negative psychological and physical adjustment, whereas appraising a stressor as a challenge is positive psychological and physical adjustment. This study examined how cognitive appraisal of PTCA(heart disease threat and treatment appraisal) related to the cardiac risk reduction behaviors(smoking cessation, low salt and low cholesterol diet, regular exercise and stress management) 6 weeks following discharge. Method: Data were collected from 50 subjects with successful primary PTCA. Result: Heart disease threat was negative related to treatment appraisal (r=-0.240, p=0.046). Psychological well-being was negative related to heart disease threat (r=-0.317, p=0.012) and positive related to treatment appraisal(r=0.402, p=0.002). The cardiac risk reduction behaviors score was negative related to heart disease threat(r= -0.296, p=0.018) and positive related to treatment appraisal(r=-0.291, p=0.020). Conclusion: More negative appraisal was related to lower the cardiac risk reduction behaviors score. But more positive appraisal was related to higher the cardiac risk reduction behaviors score. So, there is a need to develop the cognitive-behavioral intevention that increase the coping strategy to replace with positive appraisal.

Purpose: This study was done to test structural equation modeling of health-related quality of life (QOL) of men with obstructive sleep apnea in order to identify parameters affecting QOL and provide guidelines for interventions and strategies to improve QOL in these patients. Methods: Model construction was based on 'The conceptual model of patient outcome in health-related QOL' by Wilson and Cleary, using the variables; age, physiological factors, social support, cognitive appraisal, symptoms and QOL. Participants were 201 adult male patients recruited at a tertiary university hospital in Seoul. Data were collected via questionnaires, polysomnography, and clinical records. Results: Age and symptoms directly influenced QOL. Social support and cognitive appraisal about sleep did not have a direct influence on QOL, but indirectly affected it via symptoms. QOL was lower in patients who were younger and had more severe symptoms. Symptoms were more severe for patients with lower social support and more dysfunctional cognitive appraisal. When social support was lower, cognitive appraisal was more dysfunctional. Conclusion: These results suggest it is necessary to not only manage symptoms, but also apply interventions to increase social support and cognitive appraisal about sleep in order to increase QOL in patients with obstructive sleep apnea.

This study explores the types of epistemic emotions that elementary-school students experience in science classes and the cognitive appraisal factors that affect these emotions. Thirty-two fourth-grade students of an elementary school in Gyeonggi-do, South Korea, participated in 20 science periods and wrote emotional diaries at the end of each class. In addition, the researcher conducted follow-up interviews to investigate the types of cognitive appraisal factors that caused the students to experience specific epistemic emotions that were recorded in their emotional diaries. The emotional diaries and interview data were analyzed using the constant comparative method of qualitative analysis. As a result, it was found that students experienced various positive and negative epistemic emotions. In addition, the cognitive appraisal factors experienced by the students were categorized into curriculum knowledge, experimental materials, experimental content, students, teachers, themselves, and integrated factors. We discussed that students' epistemic emotions are constructed cognitively and socially and that students inevitably experience negative epistemic emotions during science classes.

There have been great deal of studies on adult stress but comprehensive studies on adolescent stress are not sufficient. Because adolescents have different developmental tasks from adult's, and because they spend most of their time in a structured environment such as school, the research on adolescent stress is necessary. So, this study empirically investigated the types of stress and coping which students experience and their coping mechanisms in a stressful situation. In this study, perceived social support was considered as stuructural variable, and cognitive appraisal as a process variable, while existing researches tried to explain the coping mechanism only from the viewpoint of structure, or hypothesized the structure variable in the process term. The relation ships between cognitive appraisal and perceived social support on coping behavior were evaluated. Survey on 519 high school students in Seoul showed that cogitive appraisal was a structural variable which varied across the types of stress, and that perceived social support was a structure variable which was independent of the type of stress. Cognitive appraisal was related more to the qualitative process of stress appraisal than coping behavior, and perceived social support was an important structure which influenced both the appraisal process and coping behavior.

Emotion directly affects consumer buying behavior. This study examines Chinese consumers' emotion elicitation process toward a U.S. apparel brand in the Chinese market. Employing a cognitive appraisal theory, this study proposed and tested a conceptual model incorporating three factors of consumer global orientation as antecedents of consumer emotion and purchase intention as a consequence of emotion. Among the ten proposed hypotheses, eight were supported. Of the three antecedents of consumer emotion, exposure to global mass media and cultural openness positively increased Chinese consumers' appraisals of a U.S. apparel brand. Unlike these two antecedents, the effects of exposure to mass migration on consumer appraisals were found to be non significant. The relationships between appraisal dimensions and positive emotion were all supported. Finally, this study confirmed that positive emotions increased Chinese consumers' purchase intentions of a U.S. apparel brand. Theoretical and managerial implications were discussed based on the findings.

This study would review how important to define emotional intelligence could be in measuring individual differences in emotional experience. For this purpose, the definitions of emotion, built by psychological theorists, would first reviewed, in connection to the newly developed techniques in the area of emotional engineering. Comparing peripheral theories of emotion and cognitive appraisal theories, the multi-facets of emotional experience would be illustrated and it would discussed what these facets mean to predict emotional health of individuals.

Purpose: The objectives for this study were to identify the factors that correlate with appraisal of illness and to explore what variables are predictive of cancer patients primary caregivers' cognitive appraisal for stress. Method: The subjects were selected by convenient sampling and 130 caregivers who completed a questionnaire. Measures used in this study included the Family Inventory of Resources for Management, Social Support Index, Family Crisis Oriented Personal Evaluation Scales and Family Coping Coherence Index. Pearson correlation was used to identify the relationship among factors and multiple regression was used to determine the individual and cumulative effect of potential predictors on the caregivers' appraisal. Results: Patient's level of activity, severity of the disease, quality of relation between patient and caregiver, caregiver's subjective health status, economic status, family resources and coping were significantly correlated. Among the variables, coping, family resources, economic status and quality of relation between caregiver and patient predicted 49.2 percent of the variance in appraisal of caregivers' stress condition. Conclusion: These findings suggest that coping mechanisms and family resources are important for positive appraisal. Nurses should provide adequate nursing care for the primary caregiver about professional care information and supportive counseling.

Objective: This study is to review three representative psychological perspectives that explain scientific construct of emotion, that are the discrete emotion model, appraisal model, and dimensional model. Background: To develop emotion sensitive interface is the fusion area of emotion and scientific technology, it is necessary to have a balanced mixture of both the scientific theory of emotion and practical engineering technology. Extensional theories of the emotional structure can provide engineers with relevant knowledge in functional application of the systems. Method: To achieve this purpose, firstly, literature review on the basic emotion model and the circuit model of discrete emotion model as well as representative theories was done. Secondly, review on the classical and modern theories of the appraisal model emphasizing cognitive appraisal in emotion provoking events was conducted. Lastly, a review on dimensional theories describing emotion by dimensions and representative theories was conducted. Results: The paper compared the three models based on the prime points of the each model. In addition, this paper also made a comment on a need for a comprehensive model an alternative to each model, which is componential model by Scherer(2001) describing numerous emotional aspects. Conclusion: However, this review suggests a need for an evolved comprehensive model taking consideration of social context effect and discrete neural circuit while pinpointing the limitation of componential model. Application: Insight obtained by extensive scientific research in human emotion can be valuable in development of emotion sensitive interface and emotion recognition technology.

The purpose of this research is to find relationships between safeguards' personality traits and stress coping behaviors. The findings then could provide data to adapt safeguards to their duties. For that, personality traits such as sociability, stability and stress coping behaviors and the effects were investigated. In addition, cognitive aspects which were known to influence stress coping behaviors were appraised. The findings of this research are as follows, First, regarding personality traits and stress coping behaviors, the unstable and unsocial group used the emotion-focused coping style more than the stable and social group. The two groups didn't show any significant differences in the problem-focused coping style. The A-type group used both the problem-focused style and the emotion-focused style more than the B-type group. The common characteristic of the unstable, the unsociable and the A-type groups was the heavy use of avoidance behaviors of the emotion-focused coping style. Second, In the correlation between the personal traits and the stress coping effects regarding adaptability, the stability influenced stress coping effects. Third, regarding the personality traits, the coping styles and the coping effects, A-type group showed high correlation with the sociability but not with the stability. The problem-focused coping style showed high correlation with the emotion-focused style. Fourth, the cognitive appraisal on the stress causes influenced the stress coping styles but not the stress coping effects. Fifth, the cognitive appraisal on the same stress causes didn't show any significant differences among the personality traits.
