Problem solving by homework assignment is a process of practicing what were discussed in classrooms and thus is considered as an essential part of learning procedure in engineering education. We introduced the concept of cooperative learning, Student Teams-Achievement Division(STAD), to improve the students' learning efficiency by in-class problem solving. The instructor explained fundamental concepts, and lecture materials were handed out to compensate for the time of in-class team activity. Brief tests were given after every chapter, and team-based additional credits were given for the improvement comparing the average of previous tests of each student. This attempt of modified STAD was evaluated to have brought about a significant improvement in students' academic achievement, in addition to activating classroom atmosphere.

Brassinosteroids (BRs) are a special class of plant steroid hormones that are essential for normal growth and development. Part of confusion is whether BRs are unique to plants, because they have overlapping physiological roles with other better-studied hormones and with physiological responses caused by light. In systems designed to assay for cytokinins, the effects of BRs vary. We measured hypocotyl length for testing the ability of brassinolide (BL) to rescue double mutant between det2 and the photoreceptor null mutant phytochrome B (phyB). PHYB involved in controlling hypocotyl elongation in increased concentration of BL whereas phyBdet2 double mutant just partially rescue to phyB in white and red light indicated the involvement of BRs in PHYB regulated cell elongation. BRs regulated hypocotyl growth was delayed by BAP, a cytokinin treatment but inhibitory effects of BAPs on hypocotyl growth was slightly recovered by BL. The result indicated that the mode of action of BR and cytokinin is independent or sequential in the downstream light-regulated response control on hypocotyl elongation and also light modulated the action of BR and cytokinin in some extent.

Dendritic cells play a very important role in the immune response as antigen-presenting cells that are critical for initiating both innate and acquired immunity. They recognize, process and present foreign antigens to other key immune cells to trigger and regulate the immune response. The ability to activate these dendritic cells can be used as a treatment for various immune diseases. Maqui berry has been reported to have anticancer, antibacterial and anti-inflammatory properties. However, its effect on the activity of dendritic cells has not been studied. In this study, we investigated the efficacy of maqui berry extract in modulating dendritic cell activity. Treatment of dendritic cells with maqui berry extract induced the costimulatory molecules CD80, CD86, and MHC class I and II in a concentration-dependent manner. Furthermore, the antigen-presenting capacity of dendritic cells was inhibited, which confirms their ability to present antigens, and the production of Interleukin (IL)-12, which is important for dendritic cell activity, was increased. These results indicated that Maqui berry extract activates dendritic cells maturation by inducing the production of co-stimulatory molecules and IL-12. These results suggest that maqui berry extract may act as an effective adjuvant to enhance dendritic cell-based immune responses.

Purpose: The purpose of this study was to examine the applicability of a flipped learning course in Women's Health Nursing for nursing students. Methods: A total of 200 senior nursing students participated in flipped learning class of pregnancy, delivery and postpartum area, which included team-based learning and self-reflection for 8 weeks. One group pre-post test design was adopted and the changes in learning motivation and satisfaction were examined. In addition, reflective journals of the students were analyzed by making a qualitative content analysis. Results: Students showed a significant increase in score of learning motivation in the posttest (t=-4.47, p<.001). They had a mean of 3.90 in learning satisfaction out of possible five points. As a result of content analysis, three themes were selected: 'Improved attitude toward active learning', 'Burden caused by excessive workload', and 'Valuing to the team-based activity' To be specific, six sub-themes were selected, with three positive and three negative categories: 'improved class attention and understanding', 'positive class participation by preparing lessons in advance', 'peer interactions through discussion', 'A lot of time and effort consuming', 'stress caused by the burden of preparing lessons', and 'difficulties in cooperative activities'. Conclusion: This study supports and confirms that the flipped learning can be a creative instructional model of positive teaching-learning strategy in clinical nursing courses to enhance students' learning motivation.

Flipped learning is a pedagogic model in which the typical lecture and homework elements of a course are reversed. Short video lectures or e-learning contents or other learning materials are viewed by students at home before the in-class session, while students are mainly carried out diverse active learning activities such as the discussions, exercises, team projects and so on in class time. Recently flipped learning has been emerging as an effective teaching-learning method that can train the 21st century talents who can create creative values based on fusion competencies. Based on the experience in applying the flipped learning to the database class that is an elective course of the school of computer engineering through three semesters, this paper proposes a flipped learning model consists of 7 steps in detail. Also, this paper analyzes the effects and weak points of the flipped learning and proposes several things for the successful flipped learning application.
