This research aims to explore the effect of participation in 'peer tutoring(learning tutoring)' program designed for low achiever students, and to provide an explanation for the improvement of related extracurricular activity. For this, firstly, the study analyzed differences between goal attainment group and non-attainment group in self-directed learning readiness, learning presence and learning transfer. Secondly, the relationships between three variables were analyzed. Based on an online survey of 154 low achievers participating in learning tutoring, two research questions were examined using t-test, correlation and hierarchical multiple regression analyses. Our findings show that firstly, the academic achievement after participating in tutoring improved more than before. Secondly, there were differences in three variables by gender and grades. Also, there were differences in three variables between two groups. Finally, there was a high positive correlation between three variables, and 71% of learning transfer was explained by self-directed learning readiness and learning presence. Based on these findings, the practical implications are discussed regarding the improvement of tutoring program.

The purpose of this study was to examine the mechanism through which youth school-based mentoring program impacts mentees' psychological and school-related outcomes such as self-esteem, self-efficacy, and attitudes toward school. The hypothetical model was assumed that mentors could improve their mentees' developmental outcomes through positive relationships with mentors as good role models and enhancement of help-seeking orientation. To investigate the mediating effect of process-related outcomes, structural equation modeling was used. The 97 adolescents were recruited through referral and random selection from middle schools in Seoul. The result showed that the effects of program participation were mediated by proximal changes in connectedness to role models and development of help-seeking orientation that, in turn, led to facilitate more positive attitudes toward school and academic activity, and improve psychological outcomes. Practice and policy implications as well as further research topics were discussed to aid the search for highly effective mentoring programs.

This paper aims at investigating the developments and challenges of Northwest Pacific Action Plan (NOWPAP), a regional cooperation mechanism to protect marine environment in Northeast Asia. As one of 16 UNEP's Regional Seas Program, NOWPAP has evolved since its inception in 1994. Based on the belief that a cooperative institution may work more efficiently to address common regional concerns on marine environment, China, Japan, Russia and South Korea have developed NOWPAP under the UNEP's leadership. NOWPAP now has its own independent secretariat, and 4 regional activity centers while expanding its partnership with other institutions. However, NOWPAP must address several challenges that it now faces for better achievement of its goals. They include consideration of unique geopolitical situation in this region, participation of North Korea, incorporation of sustainable development concept in its activities, reconsideration of equal opportunity principle for more efficient cooperation, and securing sufficient financial resources.

Reaction characteristics of simultaneous removal of SOx and NOx have been investigated in a thermogravimetric analyzer and tubular fixed bed reactor using the $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst. Sulfur removal capacity of $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst is largely enhanced above both the temperature of $450^{\circ}C$ and the loading of 6wt% due to the participation of alumina support in a sulfation reaction. The NO reduction efficiency of 8wt% $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst shows the maximum value at $370^{\circ}C$ and then decreases with the increase of reaction temperature due to the oxidation of $NH_3$ gas. The presence of sulfate on the surface of sorbent/catalyst enhances the optimum reaction temperature showing the maximum deNOx efficiency. In the simultaneous removal of SOx and NOx at $250^{\circ}C$. deNOx activity of $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst is rapidly decreased due to the formation of ammonium salts such as $NH_4HSO_4$. In the simultaneous removal reaction of SOx and NOx, the optimum temperature showing the maximum deNOx efficiency increases to $400^{\circ}C$ due to the presence of $SO_2$ gas.

The 40-hour work week system has brought positive impact on shortening working hours, eliminating long-time work, increasing leisure-time with family, etc. And this has brought about an increase in leisure-life satisfaction and happiness level. The type of leisure activities has changed from passive activities such as rest to active activities such as sports, tourism. And the 40-hour work week system has positive impact on social activities such as participation in volunteer work and, club activities. Thus all efforts need to be made to establish 40-hour work week system as soon as possible in all workplace. Firstly, 40-hour work week system needs to be introduced to every workplace with less than 5 persons, enlarge 5-day school week system into every primary and secondary school, and create conditions for positive leisure activities. Secondly, labor standards supervision and administration needs to be strengthened to eliminate long-time work over 52 hours per week, below-minimum wage work.

Objective : Questionnaires completed by occupational therapists and patients in institutions conducting a "Pilot Project of Rehabilitation Medical Institutions" were used to determine whether occupational therapy was able to establish appropriate patient support systems for return to home and community. Methods : The questionnaire was completed by 293 occupational therapists from 13 institutions conducting pilot projects and 296 patients from 8 institutions who were able to respond. Results : Although the Pilot Project of Rehabilitation Medical Institutions is being implemented to enable early return of patients to activities of daily living, the most important therapeutic goal is not efficiently applied. In addition, since the health insurance systems utilized in medical institutions are applied as in the pilot project, there is no basis for evaluation and mediation of practical daily activities and vocational rehabilitation for actual return to the community. Conclusion : Through a detailed review of the pilot project, it will be necessary to improve the quality of life through the early return of patients to social activity, and to make practical improvements to reduce unnecessary societal expenditures.

The present work was undertaken to address the role of protein disulfide isomerase 2 (Pdi2) in the mercury-tolerance of Schizosaccharomyces pombe, using the Pdi2-overexpressing recombinant plasmid pYPDI2 and the corresponding vector plasmid pRS316. When exposed to mercuric chloride, the PDI2 overepxression cells grew significantly better than the vector control cells. They revealed the lower levels of intracellular reactive oxygen species (ROS) and nitric oxide (NO), when incubated with mercuric chloride for 6 h, than the vector control cells. The PDI2 overepxression cells contained the higher levels of total glutathione (GSH) and superoxide dismutase (SOD) activity than the vector control cells, after 6 h of incubation in mercuric chloride. However, the PDI2 overepxression cells contained similar levels of glutathione peroxidase (GPx) activities, compared to those of the vector control cells. Taken together, the S. pombe Pdi2 promotes the tolerance against mercury toxicity through up-regulating total GSH and SOD and subsequently attenuating ROS and NO elevations.
