'Self-esteem' is defined as 'the lived status of one's individual competence and personal worthiness in dealing with the challenges of Life over Time'. High self-esteem is associated with self-confidence, effectively coping, well-being, and responsibility and it is essential for the responsible choice and determination of environments. The purposes of this study were to develop a strategy to enhance the self-esteem and to verify the effects. A new strategy, 'Cognitive Restructuring Strategy' was based on the characteristics of self-esteem and the key idea of this was to eliminate negative thoughts and to reinforce affirmative thoughts. We developed the statement to embody this strategy and applied to the experimental group. According to the results, self-esteem for the control group(155) did not changed but that for the experimental group(158) was significantly enhanced. Continuously, environmental learning instructions of 3 units were carried out on two groups. By applying the t-test, achievement-test scores for the experimental group per unit were significantly higher than those of the control group as regards the four respective goals of EE. Therefore this strategy and statement are helpful in enhancing self-esteem and it was found that 'self-esteem' is a influential factor to form environmental responsible behaviors(ERB).

A lignan derivative, (-)-(7R, 8S)-dihydrodehydrodiconiferyl alcohol (DHDA), was isolated from Kalopanax septemlobus L. and was observed to have neuritogenic activity. DHDA at 50 $\mu$M caused a marked induction of neurite outgrowth and an enhancement of nerve growth factor (NGF)-mediated neurite outgrowth from PC12 cells. However, it did not exhibit any neurotrophic action. At 50 $\mu$M, DHDA enhanced NGF-induced neurite-bearing activity. This activity was partially blocked by the mitogen-activated protein kinase (MAPK) inhibitor PD98059 and by GF109203X, a protein kinase C (PKC) inhibitor. These results suggest that DHDA can induce neurite outgrowth and enhance NGF-induced neurite outgrowth from PC12 cells by amplifying up-stream steps such as MAPK and PKC.

Purpose : This study aims to assess the impact of the emotional labor on female dental clinic employees' intention to leave, and the moderating effect of internal marketing, reducing the intention to leave and providing basic data for an effective human resources management of dental clinics. Methods : The structured self-administered questionnaires were distributed to dental hygienists, dental assistants and other employees (including administrative staff and dental coordinators, but excluding dentists) working at a dental hospital and at dental clinics in the Busan and Gyeongnam area. This study used SPSS Windows version 18.0 program (Chicago, IL, USA) to perform frequency factor, reliability, correlation, and hierarchical regression analyses were performed using SPSS. Results : First, emotional labor had a positive effect on the intention to leave. Two components of the internal marketing, communication and employee welfare system, had a significant moderating effect on the relationship between employees' emotional labor and their intention to leave, while the education/training component of the internal marketing showed no moderating effect. Conclusion : Enhancement of communication and the employee welfare system will help dental care organizations reduce their employees' emotional labor and hence employees' turnover.

Objective: Meditation can elicit trait-like changes in psychological and social styles, as well as enhancement of emotional regulatory capacity. We investigated the relation between personality traits and emotional intelligence in meditation practitioners. Methods: Seventy-two long-term practitioners of mind-body training (MBT) and 62 healthy comparative individuals participated in the study. The participants completed emotional intelligence questionnaires and the Myers-Briggs Type Indicator (MBTI). Results: The MBT group revealed higher scores on all five emotional intelligence factors than did those in the control group, such as emotional awareness and expression, empathy, emotional thinking, emotional application, and emotional regulation (all $p{\leq}0.001$). MBT practitioners also had higher scores on the intuition of perceiving function (t=-2.635, p=0.010) and on the feeling of the judging function (t=-3.340, p=0.001) of the MBTI compared with those in the control group. Only the MBT group showed a robust relationship with every factor of emotional intelligence and MBTI-defined intuitive styles, indicating that higher scores of emotional intelligence were related to higher scores for intuition. Conclusion: Emotional intelligence of meditation practitioners showed notable relationships with some features of personality trait. In-depth associations between emotional intelligence and personality traits would help to foster psychological functions in meditation practitioners.

Teacher quality is a key factor that determines quality of education. Being aware of this, the Korean government and teachers have been striving to improve teachers' professionalism. Research about the impacts of efforts to enhance teacher professionalism on students' academic achievement and course satisfaction, however, is extremely limited. This study sought to advance our understanding of the relationship between these factors by analyzing what teacher characteristics impact students' achievement and satisfaction. To this end, the study drew on the middle and high school data from 3rd to 6th year survey of the Seoul Educational Longitudinal Study. Structural equational modeling were used as the main approach. Latent profile analysis, a kind of mixture modeling analysis, were used as needed. This study found that teachers' participation in instruction enhancement activity and professional development impact students' attitude toward mathematics lessons and their perception on class atmosphere, and ultimately impact their academic achievement as well as their overall satisfaction in the course. In addition, teachers' use of EBS textbooks and videos impact 3rd grade high schoolers' academic achievement. These findings suggest that effort to improve teacher professionalism positively impact students' academic achievement and course satisfaction, although there is a difference according to the year grade. This study provides implications for education policy makers and teacher educators.

The tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) initiates the extrinsic apoptotic pathway through formation of the death-inducing signaling complex (DISC), followed by activation of effector caspases. TRAIL receptors are composed of death receptors (DR4 and DR5), decoy receptors (DcR1 and DcR2), and osteoprotegerin. Among them, only DRs activate apoptotic signaling by TRAIL. Since the levels of DR expressions are higher in cancer cells than in normal cells, TRAIL selectively activates apoptotic signaling pathway in cancer cells. However, multiple mechanisms, including down-regulation of DR expression and pro-apoptotic proteins, and up-regulation of anti-apoptotic proteins, make cancer cells TRAIL-resistant. Therefore, many researchers have investigated strategies to overcome TRAIL resistance. In this review, we focus on protein regulation in relation to extrinsic apoptotic signaling pathways via ubiquitination. The ubiquitin proteasome system (UPS) is an important process in control of protein degradation and stabilization, and regulates proliferation and apoptosis in cancer cells. The level of ubiquitination of proteins is determined by the balance of E3 ubiquitin ligases and deubiquitinases (DUBs), which determine protein stability. Regulation of the UPS may be an attractive target for enhancement of TRAIL-induced apoptosis. Our review provides insight to increasing sensitivity to TRAIL-mediated apoptosis through control of post-translational protein expression.

We present 2-dimensional continuum radiative transfer modeling for EC53. EC 53 is a Class I YSO, which was brightened at $850{\mu}m$ by a factor of 1.5. This luminosity variation was revealed by the JCMT Transient Survey. The increase in brightness is likely related to the enhanced accretion. We aim to investigate how much increase of protostellar luminosity causes the observed brightness increase at $850{\mu}m$. Thus we modeled the SED of EC 53 both in the quiescence and (small scale) outburst phases, with and without the external heating from the interstellar radiation field (ISRF). We found that the internal protostellar luminosity should increase more to fit the observed flux enhancement if the ISRF is considered in the model.

As software development technology evolves, the quality of software has increased. But software created through sophisticated technology is still defective. The developer will be aware of the defect through a bug report and the reported defect must be fixed as soon as possible for the software to function correctly. It is important to know which component of the program is related to the reported defect and should be fixed. However, even though the developer understands the developed software, the task of tracing faults is a time-consuming task and requires effort. Therefore, if there is a way for developers to support tracing faults, they could fix defects more quickly. Because fixing defects rapidly is a factor of software reliability, fault traceability is essential and an effective method is needed. Therefore, in this paper, we propose a model-based fault traceability enhancement technique by using bug report and commit information and verify the effectiveness of the proposed technique.
