E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.

The purpose of this study is to develop and implement an alternative elementary science curriculum to enhance creative problem solving abilities. The curriculum consisting of three main elements was developed. The three elements are content knowledge, process knowledge and creative thinking skills. The curriculum was validated by more than 10 science educators, scientists, and curriculum specialists. In order to implement the curriculum, three lessons for 5th grade were developed and taught by a problem-based-learning(PBL) method in an experimental group during the second semester. For the comparison group the ordinary lesson based on the 6th national science curriculum was taught by the same science teacher during the same period. Performance assessment was developed and used for the pre and post test. Two-way ANOVA, and T-test were used to check whether there are any significant differences between the gains of scores(pre-post test) of the two groups. The results of the test showed that the experimental group increased significantly in the total creative thinking problem solving skills, but the comparision group did not.

Recently, Co-working that is a new trend of working and Co-working Space that create Co-working are increasing rapidly around the centers to support start-up such as one-person creative companies. However, the business centers located outside Seoul are not enough to recognize knowledge and skill for operating Co-working Space. Therefore, this study selects the big research issue which is "The recognition and case of co-working & application to co-working space" and the small research issue that is "Co-working Space operation activities" for qualitative research by using in-depth interview to managers of one-person creative company business centers. As a result, on the perspective of the big research issues, they understood Co-working concept, but the Co-working case was made by manager's effort without voluntary participation of the users. Co-working Space is important to recognize as a space for interaction and exchange information but was used only as a sharing space. And on the perspective of the small research issues, 'Space & Interior', 'Alliance and Partnership' and 'Community and Communication' show low awareness and activities. So, we suggest improvement plans through the case of best practices. This study is valuable, it could be a help to adapt and improve to Co-working Space in one-person creative company business center for creation of performance by Co-working.

Schisandra chinensis is a traditional herbal medicine that is widely spread in Korea, Japan, and China. The fruits of S. chinensis Bailon, known as omija in Korea, have traditionally been used for the treatment of coughs, fatigues, and insomnia. Up to now, there have been several reports for the identification of major lignan compounds and their quantitation in S. chinensis extracts. To the best of our knowledge, however, there is no report on the analysis of lignans in omija wine and omija cheong (sugared omija or omija sugar syrup). In the present study, seven dibenzocyclooctadiene lignans (gomisin A, gomisin B, gomisin C, gomisin N, schisandrin, deoxyschisandrin, and wuweizisu C) in omija wine and omija cheong were analyzed and quantitated using liquid chromatography-tandem mass spectrometry. Among seven lignans, pharmacologically active gomisin A, schisandrin, and deoxyschisandrin, which are major components in fruits of S. chinensis, were the most abundant lignans in omija wine and cheong. The content of lignan in omija wine was in the order: schisandrin > gomisin A > deoxyschisandrin > gomisin N > gomisin B > gomisin C > wuweizisu C. The concentration of deoxyschisandrin and gomisin N in omija wine was approximately 2.0- and 6.0-fold higher than for omija cheong. Additionally, this study provided a systematic identification of lignans in omija wine and cheong and indicated that the omija wine and cheong might be of value for their dietary application.

In this study, a problem-centered learning based STEAM field experience learning program was developed and the effects of applying it were investigated. The program was composed of 8 sessions by using problem-centered learning education method and integrating STEAM elements between disciplines. The contents of program are as follow. In the step of sharing problems and making a problem-solving plan, they understood the various examples and meanings of endangered species, explored the project activities, and made an inquiry plan. In the search and re-exploration phase, a smart device was used to investigate the appearance, habitat environment and cause of extinction for Clithon retropictus, and a site inquiry plan was established for each group. Then, they moved to the field to explore brackish-headed gallops and discuss ways to protect endangered species. In the step of creating a solution, a web-based report was produced as the final product using smart devices based on the results of the inquiry. In the presentation and evaluation stage, the produced web-based report was used to present each group, conduct mutual evaluation, and organize project activities. The developed program was applied to 6th grade 29 students enrolled in the J University Gifted Education Center. In order to find out the effectiveness of the program, tests of science process skill, creative problem-solving ability, and scientific attitude were conducted before and after of program learning, and the results were statistically analyzed by t-test. In addition, a STEAM program satisfaction test was conducted after project in order to find out the satisfaction of the class. As a result of application of the program, the results were significantly improved in openness, criticism, and creativity among the sub-factors of creative problem-solving ability and scientific attitude. Satisfaction with the STEAM program was also high, but no significant result was found in science process skill. Therefore, the program of this study could be influenced on improvement of creative problem-solving ability and scientific attitude of gifted students in elementary science.

The purpose of this study is to investigate the effect of chemistry program based on metacognitive learning strategies using realistic contents on prospective teachers' creative thinking skills and science core competencies, and their perception. In particular, it was intended to further improve the effectiveness of the program by introducing a strategy to strengthen metacognition. Participants were classified into the experimental group subject to the newly developed chemistry curriculum and traditional group subject to general programs that exclude realistic contents and metacognitive strategies. Both groups were surveyed before and after the application of the program to measure the degree of change in metacognitive competencies, creative thinking competencies, and science core competencies. It also analyzed the impact of metacognitive competencies and science core competencies on creativity thinking competencies. As a result of the study, relevance and rationality among sub-factors of metacognitive competencies and creative thinking competencies of the experimental group were improved, and all sub-factors except for scientific participation and lifelong learning ability among science core competencies were significantly improved. In addition, it was found that metacognitive knowledge among metacognitive competencies, scientific inquiry ability and scientific thinking ability among science core competencies affect creative thinking competencies. Through the results, it was suggested that realistic content that incorporates metacognitive learning strategies is needed to improve creative thinking competencies, and learning models and programs that can utilize them are needed.
