  • Focused electron beams with high energy acceleration are versatile probes. Focused electron beams can be used for high-resolution imaging and multi-mode nanofabrication, in combination with, molecular precursor delivery, in an electron microscopy environment. A high degree of control with atomic-to-microscale resolution, a focused electron beam allows for precise engineering of a graphene-based field-effect transistor (FET). In this study, the effect of electron irradiation on a graphene FET was systematically investigated. A separate evaluation of the electron beam induced transport properties at the graphene channel and the graphene-metal contacts was conducted. This provided on-demand strategies for tuning transfer characteristics of graphene FETs by focused electron beam irradiation.

  • An iterative focused wave generation method is developed and implemented in a local analytic based Navier-Stokes solver. This wave generation method is designed to reproduce the target focused wave by matching the target amplitude spectrum and phase angle. A 4-waves decomposition scheme is utilized to obtain the linearised component of the output wave. A model test studying the interaction between different focused waves and a fixed cylinder is selected as the target for the wave generation approach. The numerical wave elevations and dynamic pressure on the cylinder are compared with the experimental measurement and other state-of-the-art numerical methods' results. The overall results prove that the iterative adjustment method is able to optimize the focused wave generated by a CFD approach.

  • 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.

  • Objective: This study investigates the main effects and interaction effects of mother's reactions to young children's negative emotions on the children's problem behaviors. Methods: A total of 346 mothers with toddlers completed questionnaires, the data were analyzed using Pearson's correlation coefficient and multiple regression. Results: First, mothers' supportive response to young children's negative emotions, including expressive encouragement, emotion-focused reactions, and problem-focused reactions, showed negative relations with the children's internal and external problem behaviors. Mothers' unsupportive response to children's negative emotions, including distress reactions, minimization reactions, and punitive reactions, showed positive relations with the children's internal and external problem behaviors. Second, an interactive effect was observed. For external problem behavior, mothers' lower distress reactions accompanied by higher emotion-focused reactions, lower punitive reactions accompanied by higher emotion-focused reactions, lower distress reactions accompanied by higher problem-focused reactions, and lower punitive reactions accompanied by higher problem-focused reactions all decreased children′s problem behavior. However, for internal problem behavior, only mothers' lower distress reactions accompanied by higher emotion-focused reaction decreased children′s problem behavior. Conclusion/Implication: The main interaction effect on mothers' reaction to young children's negative emotional expression shows that preventive intervention is needed to address problem behavior.

  • This study focused on the relationship between ego- resilience and stress coping styles of male and female adolescents. The study also tried to identify differences in stress coping styles based on sexual differences and the level of ego- resilience in adolescents. Ego-resilience showed a positive correlation to problem-focused and social support seeking coping styles and a negative correlation to emotion-focused coping style for both male and female adolescents. Canonical Correlation analysis revealed that self-confidence among four sub-domains of ego-resilience made the most outstanding contributions in predicting stress coping styles of female adolescents. The self-confident female adolescents tended to use the problem-focused coping style. For male adolescents, the optimistic attitude among four sub-domains of ego-resilience was the most significant factor in predicting emotion-focused coping style. Female adolescents tended to use more varied coping strategies than male adolescents in stressful situations. The group of adolescents who had a higher level of ego-resilience reported more problem-focused and social support- seeking coping styles in stressful situations. Conversely the group of adolescents with lower level of ego-resilience tended to use emotion-focused coping strategy. The results of this study have important implications for theory, research, and practice. Development of ego-resilience in adolescents based on sexual differences was an important task for their effective coping strategies.

  • Purpose: This study was done to analyze the effect of supervisor-focused impression management behavior of the airline cabin crew on perceived customer empathy. It focused on verifying dual meanings of the crew's emotional expression divided into surface acting and deep acting. Research design, data and methodology: The survey was conducted on cabin crews of two major Korean airlines. The reliability and validity of each variable used in the questionnaire were verified. Then, each hypothesis was analyzed through multiple regression analysis. Results: Firstly, the crew's supervisor-focused impression management behavior had a significant effect only on surface acting of the crew's emotional labor behavior. Among the crew's supervisor-focused IM behaviors, verbal IM behavior had a greater influence on surface acting than non-verbal IM behavior. Secondly, there was no relationship between the crew's supervisor-focused IM behavior and the crew's deep acting. Thirdly, the crew's emotional labor behavior (surface acting & deep acting) had a significant effect on perceived customer empathy. Fourth, the crew's deep acting had a greater influence on perceived customer empathy than surface acting. Conclusions: Cabin crews receive double evaluation from their immediate supervisors and customers. As a result, it was confirmed that the crew's supervisor-focused IM behavior, the crew's emotional labor behavior, and perceived customer empathy were connected process.
