By combining with Gabor filter, Local Binary Pattern algorithm(LBP) and k-Nearest Neighbor algorithm(KNN) are facial emotional features extracted and recognized. Meanwhile, facial emotional features put influence on robot's emotion state, which is described in AVS emotion space. Then the optimization of smart home environment on the cognitive emotional model is specially analyzed using simulated annealing algorithm(SA). Finally, transition probability from any emotional state to a state of basic emotions is obtained based on the cognitive reappraisal strategy and Euclidean distance. The simulation and experiment have tested and verified the effective in reducing negative emotional state.展开更多

Patients and Methods: The study employed a qualitative design from May to October of 2010, in a private university hospitals outpatient gnecologic oncology clinic in Ankara, Turkey. Content analysis with an inductive approach had been used to analyze 32 interviews that served as the data base for this study. Interview form that focused on what gynecologic cancer women felt to living with a colostomy. Results: Findings also reveal that gynecologic cancer patients with colostomy experience many uneasy feelings that affect their emotional state. The content analysis resulted in the development of two thematic units. The first we described as “To experience the consequences of stoma as a gynecologic cancer patients”. The second was “suffering experienced-being challenged the consequences of the stoma”, and the third was “promote self management-normalization of the new condition”. For the psychological support, family and friends’ support has been mentioned as the most important part that can release their anxiety. Conclusions: We concluded that a having stoma was difficult for the women. The emotional state of the women when they get colostomy was typically characterized by fear, and worry about their current process. Body image, self-esteem, social activity, sexuality were the aspects that most affected the patients. Nurses have very important role within holistic approach and empathetic interaction, for determining major problem areas.展开更多

We compared the change in the emotional state of 270 participants, using the Japanese version of the Positive and Negative Affect Schedule (PANAS), before and after the intervention. The intervention conditions included: verbal description of one’s positive future on a worksheet (the language description condition), and imagining one’s positive future (the imagery condition). The results of the experiment showed that after the intervention, the scores of the imagery group on the positive and negative affect scales of the PANAS were significantly higher and lower, respectively, than those of the language description group. We also found that the amount of change in the scores of the positive and negative affect scales of the PANAS was significantly larger in the imagery group as compared to the language description group. These results indicate that interventions involving the imagining of one’s future via the time machine question of the solution-focused approach have a more direct impact on emotional states than interventions using a language description. This suggests that mental imagery plays an important role in interventions carried out within the framework of the solution-focused approach.展开更多
