This research aimed to determine how a combined yoga and tea meditation program would affect the happiness of adolescents. The investigation was conducted over a total of 11 sessions held twice a week with 15 female middle-school students. Each session lasted 90 min and comprised preparation for 5 min, Hatha yoga for 50 min, tea meditation for 15 min, the expression of feelings for 15 min, and 5 min were allocated to finishing the program and announcing the next session time. A t-test was performed before and after the program to analyze the effects of the program. A goodness of fit test, which is related to the improvement of happiness, was done through a path analysis. As a result, we were able to determine meaningful changes in the t-test scores of happiness, stress, and quality of life. The scores of mindfulness, physical self-concept, and self efficiency changed positively, but meaningful changes were not shown. To derive a final conclusion, we verified the mediator effect with respect to happiness through a structural model. Consequently, physical self-concept was activated as a promoter for improving self-efficiency and mindfulness. Mindfulness was the key factor that improved the happiness of the adolescent subjects.

The purpose of this study was to investigate characteristics of teenagers' perceptions to bullies according to the classification types of Q-methodology. The results of the analysis were classified in 5 types. Type 1, which was the type geared foward solution, showed that they expressed a strong attitude of sympathy and protection towards the victim. However, they had harbored rage and hostile feelings against the assaulter. For example, when they witnessed the bully in action, they positively intervened in the situation. Type 2, which was the observer type, showed that they thought the victims were to blame for their misfortune. Also, when a friend who was left out in the cold by his classmates, they were just watched without showing any special interest. Type 3, which was the type of conflict, indicated that they believed that the both the victim and the assaulter should have responsibility. In contrast to the previous type, they had sympathy for the friend who was left out in the cold by his classmates, they had the dual feeling that intended to use the bully under the situation with his friend. Type 4, which was the type of assenting, indicated that they assumed an indifferent attitude to the situation, while they implied assenting to the situation of the friend who had a bad relationship with them. Type 5, which was the negative type, showed that they had the negative view to the situation of bully itself so that they did not recognize the bully as the method of revenge for whatever reason. The results of the study showed that the bully increased the factor of stress to school life of the victim or assaulter, even in the subjective position. The perception of the bully should change according to the characteristics of the types of people and it is necessary to study how to cope with the situations.

Emotional expression is universal and emotional state impacts important areas in our life. Until now, analyzing the acquired EEG signals under circumstances caused by invoked feelings and efforts to define their emotional state have been made mainly by psychologists based on the results. But, recently emotion-related information was released by research results that it is possible to identify mental activity through measuring and analyzing the brain EEG signals. So, this study has compared and analyzed emotional expressions of human by using brain waves. To get EEG difference for a particular emotion, we showed specific subject images to the people for changing emotions that peace, joy, sadness and stress, etc. After measured EEG signals were converged into frequence domain by FFT signal process, we have showed EEG changes in emotion as a result of the performance analyzing each respective power spectrum of delta, theta, alpha, beta and gamma waves.

This study deals with a counseling case in which a mother requested counseling due to the problems of her daughter, who suffers from multiple tic disorder. The participants of this study included five family members (grandmother, father, mother and two female children) and a total of 23 sessions were held from September 2006 to December 2007. Additional counseling ($24^{th}$ counseling session) was conducted on April 1st, 2009. The data was based on recorded transcripts and notes from 24 family therapy sessions. The study used a constant comparative analysis, which uses matrix and network display as an analysis method suggested by Miles&Huberman(1994). The characteristics of the family of origin and the indifference of the husband had caused the wife stress. The couple had frequent conflicts due to dysfunctional communication methods, a clash of values, sexual dissatisfaction, and a lack of communication. This marital conflict became the primary factor of the daughter's multiple tic disorder. Intervention of the family therapist resulted in the setting of treatment goals based on MRI's communication theory and Bowen's family systems theory in order to solve the problem of the daughter's multiple tic disorder. Also, the therapist's intervention techniques included exploring experiences with the family of origin, shedding light on the multigenerational transmission process, exploring dysfunctional attempts at solutions, the therapist's self-disclosure, providing similar cases, dealing with resistance, and suggesting a new communication method. To solve the problem, the therapist helped the family separate the daughter spatially from her parents. Therefore, the therapist's intervention helped reduce the daughter's tics and improve relationships among the family.

In this research, recombinant human cytotoxic T-lymphocyte antigen 4-immunoglobulin (hCTLA4Ig) was produced by transgenic rice cells. RAmy3D promoter was used for overcome the limitation of low expression level in transgenic plant cells, and the secretion of target protein was accomplished by signal peptide. However, the RAmy3D promoter system which can be induced only by sugar starvation causes the decrease of cell viability. As a result, cell death promotes the release of protease which degrades the target proteins. The protein stability and productivity can be significantly influenced by proteolysis activity. Therefore, development of new strategies are necessary for the in situ recovery of target proteins from cell culture media. In this study, in situ recovery was performed by various strategies. Direct addition of Protein A resin with nylon bag leads to cell death by increased shear stress and decrease in production of hCTLA4Ig by protease. Medium exchange through modified flask could recover hCTLA4Ig with high cell viability and low protease activity, on the other hand, the productivity was lower than that of control. When in situ recovery was conducted at day 7 after induction in air-lift bioreactor, 1.94-fold of hCTLA4Ig could be recovered compared to control culture without in situ recovery. Consequently, in situ recovery of hCTLA4Ig from transgenic rice cell culture could enhance productivity significantly and prevent degradation of target proteins effectively.

Solid oxide fuel cells (SOFCs) are among one of the promising technologies for efficient and clean energy. SOFCs offer several advantages over other types of fuel cells under relatively high temperatures (600℃ to 800℃). However, the thermal behavior of SOFC stacks at high operating temperatures is a serious issue in SOFC development because it can be associated with detrimental thermal stresses on the life span of the stacks. The thermal behavior of SOFC stacks can be influenced by operating or material properties. Therefore, this work aims to investigate the effects of the thermal conductivity of each component (anode, cathode, and electrolyte) on the thermal behavior of samarium-doped ceria-based SOFCs at intermediate temperatures. Computational fluid dynamics is used to simulate SOFC operation at 600℃. The temperature distributions and gradients of a single cell at 0.7 V under different thermal conductivity values are analyzed and discussed to determine their relationship. Simulations reveal that the influence of thermal conductivity is more remarkable for the anode and electrolyte than for the cathode. Increasing the thermal conductivity of the anode by 50% results in a 23% drop in the maximum thermal gradients. The results for the electrolyte are subtle, with a ~67% reduction in thermal conductivity that only results in an 8% reduction in the maximum temperature gradient. The effect of thermal conductivity on temperature gradient is important because it can be used to predict thermal stress generation.
