Purposes of this study were to explore the process of experience that science teachers go through when participating in peer coaching meetings to improve teaching ability and to find out factors that affect each process of experience. The data were collected through recording of peer coaching meetings, videotapes of science class, and interviews. All the data were analyzed after transcription. The results of the study showed that even though Teacher K broke the ice and formed consensus among the peers by developing Content Representation (CoRe) at the beginning of the meetings, he became self-defensive rather than receptive of peers' opinions on the recorded class at the discussion session. But as the peer coaching went on, he realized that peer coaching was not about evaluation but rather on improving his teaching ability. In turn, he was able to look at his teaching in a more objective point of view and accepted suggestions from peer coaching discussion. The self-reflection of Teacher K acted as the key factor in the efforts to improve his teaching ability. He sought the concrete alternatives through the class analysis with fellow teachers and showed major changes in his teaching practice from the language habits, pronunciation, and speed of his speech to the interaction with students and class design. However, there was little change in knowledge of curriculum and assessment due to his strong orientation to improve students' grades as an academic high school teacher. Likewise, it was found that while peer coaching exert a strong influence on instructional methods and strategies of Teacher K, his strong orientation to improve students' grades hinders a balanced development of subcomponents of PCK.

This study sought to investigate the effects of cooperative learning emphasizing interactions on science-gifted elementary students' scientific creativity. Thirty-four science-gifted elementary students were divided into an experimental class and a comparison class to compare their creativity scores quantitatively. The experimental class participated in cooperative learning emphasizing interactions, and the comparison class participated in whole class interactions. For qualitative analysis, the small group discussions were audiotaped and transcribed. The results of the study are as follows. First, cooperative learning emphasizing interactions had a positive educational effect on usefulness, which is one of the essential elements of scientific creativity. Second, as the cooperative learning progressed, the interaction between the small group members improved qualitatively. Third, the factors hindering the effectiveness of cooperative learning included negative task-unrelated statements from some of the small group members and the following operational statements to correct them. Based on these results, this study proposed some suggestions for effective cooperative learning emphasizing interactions.

Grey literature is a non-Public data only for nonprofit users. Some of the major grey literatures are technical report, Proceeding, and thesis. For their Promptitude, these sources are core of research and development. According to a research on the academic qualify. grey literatures have higher usage rates than books-articles excluded. Also, the usage of foreign grey literature by librarians of research organization was investigated. The result was that over 90 percent of the researchers were demanding the original text of the foreign grey literature. In addition, librarians pointed out that the time-consuming problem and the lack of published information was a hindrance to using grey literature. For the centralized management of grey literature. they wanted an alliance structure.

Secondary school science teachers' preception on inquiry learning was investigated by using questionnaires. According to these results, science teachers, who are participants of the current Korea National Science Curriculum, responded that raising the 'interest in science' was the most important objective of science education, and using practical scientific subject matters in class will do such. More than 72% of science teachers have used reconstructed materials. When reconstructed textbook contents were used, teachers through that the most important object is the 'acquirement of scientific knowledge'. Most science teachers perceived inquiry leaning as a student centered open investigation. Among factors that disturb inquiry leaning, critical ones were 'entrance examination', 'lake of teaching-leaning materials', 'little understanding of inquiry leaning', and 'lake of student's will to inquiry'.

Objectives: This study analyzed the education participation reasons and deterrents of dietitians who work in welfare facilities for the elderly. Methods: The survey was completed by 144 dietitians working at welfare facilities for the elderly in Korea. The survey was conducted in October, 2018, both on-line and off-line, based on the demographic characteristics, work status on welfare facilities for the elderly, Participation Reasons Scale (PRS) and Deterrents to Participation Scale (DPS-G). The data were analyzed using frequency analysis, descriptive analysis, factor analysis, reliability analysis, regressive analysis using SPSS ver. 25.0. Results: The reason for participation were divided into three factors: 'Responsibility of professional and self-development ($5.76{\pm}1.04$)', 'Job stability and personal benefits ($4.98{\pm}1.28$)', and 'Interaction and development of professional competencies ($5.85{\pm}1.00$)'. 'Interaction and development of professional competencies' was the highest motivation factor. Also, the deterrents for participation were divided into four factors: 'Dispositional barrier ($2.70{\pm}1.29$)', 'Dissatisfaction of education usability ($3.39{\pm}1.38$)', 'Institutional barrier ($4.21{\pm}1.45$)', and 'Situational barrier ($2.36{\pm}1.30$)'. 'Institutional barrier' showed the highest deterrents factor. In addition, 'Responsibility of professional and self-development' and 'Interaction and development of professional competencies' were negative attributes for 'Dispositional barrier' (p<0.001). Conclusions: These results provide basic data to promote participation in education and contribute to the improvement of their job ability and education capacity of the food and nutrition management of welfare facilities for the elderly.

In an offline system, the bank does not participate in payments. As a result, it is difficult to make the refund spendable. Due to this, current offline systems do not provide spendable refunds. In these systems, a check consists of two parts: a spendable part and a refund part. A client uses the spendable part during the payment phase, and uses the refund part to get the refund for the remainder of the check. Therefore, a client cannot reuse the remaining and must always refund it. Moreover, the relationship between the spent amount and the refund amount can be used to guess which check the client used when the client refunds the remaining. To remedy these problems, we propose a new offline system which allow clients to reuse the remaining values of the check. This system provides unlinkability of the payments made by using a single check. It also provides mechanisms to detect and identify clients who perform misconduct such as double spending and over spending. The required overall computational cost to withdraw, spend and refund a check in our system is lower than using several checks in other offline systems.

This study examines how path dependency of working poor labor market segmented from the primary and the secondary labor market affects employment and quality of employment of working poor. It Further examines how path dependency makes working poor to remain in the labor market and makes it difficult for them to escape from a vicious poverty cycle. Data is based on the $3{\sim}7th$ Korea Labor and Income Panel Study(KLIPS). Markov's transition probability and discrete-time hazard analysis are used for analysis. This study finds that Korea labor market is divided into three parts; the primary labor market, the secondary labor market and the working poor labor market. The proportion of employed poor has been reduced, but the proportion of non economically-active working poor has been increased and has become the main group among the working poor. This shows that labor demand of working poor is fundamentally lacking and there are structural barriers that block working poor's employment itself. The regression analysis shows that the longer working poor labor market participation is, the lower poverty-exit rate. This is an evidence of vicious poverty cycle that the poor have little chance to exit from working poor labor market, once they step into it. Therefore, the longer their participation in poor labor market, the more likely they would move only within the closed working poor labor market. Consequently, it is necessary to fundamentally reform labor market structure and to alleviate negative perception and discrimination about the poor labor while activating labor demand.

Among a variety of environmental stresses heat, cold, chilling, high salt, drought, and so on exposed to plants, drought stress has been reported as a crucial factor to adversely affect the growth and productivity of plants. Therefore, to understand the mechanism for the drought stress signal transduction pathway in plants is more helpful to develop useful crops that display the enhanced tolerance against drought stress, and to expand crop growing areas. The signal transduction pathway for the drought stress in plants is largely categorized into two types; ABA-dependent pathway and ABA-independent pathway. It has been reported that two transcription factors, AREB/ABF and DREB2, play predominant roles in ABA-dependent and ABA-independent pathways, respectively. In addition to transcriptional regulation mediated by AREB/ABF and DREB2 transcription factors, post-translational modification (such as phosphorylation and ubiquitination) and epigenetic control are importantly involved in the signal transduction for drought stress. In this paper, we review current understanding of signal transduction pathway on drought stress in plants, especially focusing on the biological roles of a variety of signaling components related to drought stress response. Further understanding the mechanism of drought resistance in plants through this review will be useful to establish theoretical basis for developing drought tolerant crops in the future.
