Under the influence of the Fourth Industrial Revolution, there is a emphasis on capacity building based on computational thinking to foster talent for future. In Korea, SW education has been mandatory since 2018. Since 2017, research has been conducted on the definition of SW education capability and the development of diagnostic tools. At this time, the diagnostic tool for middle school has been revised and supplemented once in 2018 and is used so far. In response to the request from the field to expand the information diagnostic test for middle school to elementary school and high school, it began as one of the 2019 study on the effectiveness of SW leading schools. In this study, we develop a diagnostic tool for elementary and high school based on the diagnostic tool for middle school. Expert validity verification and preliminary inspections are carried out. Preliminary examinations will analyze the reliability, discrimination, and difficulty of the questions, and look forward to seeing the potential as a testing tool in the future.

The purpose of this study is to identify the perceptions of SW education among elementary, middle and high school students, parents, and teachers, and to identify the variables that influence the perception of SW education. For this study, a total of 50 elementary schools, 14 middle schools, and 8 high schools were selected from the stratified sampling method, and an online survey was conducted for students, parents, and teachers. According to the results, the questionnaires of 2,231 students, 615 parents, and 173 teachers were analyzed. According to the results of the study, students, parents, and teachers who had experienced SW leading schools had a high awareness of SW education, and school-level students showed higher recognition in the order of elementary, middle, and high school. As a result of analyzing the difference of perception according to the characteristics of the study subjects, the students were more aware of the fact that male students, students who participated in SW-related club activities, students who participated in SW-related competitions, higher class times of the desired. In the case of parents, the parents of male students, parents who taught SW-related educational activities outside the school, and the parents with high hopes had high awareness. In the case of teachers, the higher the educational experience of SW, the higher the students' perception of the desired time of 2 hours. As a result of analyzing the influence of the characteristics of the subjects on the perception through the multiple regression analysis, the students 'and parents' awareness and the degree of hemming on the SW-related education were found to have a positive effect. In addition, teacher awareness and SW education career were found to have a positive effect.

This paper aims at analyzing SW club acitivities on the science core high school using information disclosure. Targeting 103 schools across the nation science core high schools, the factors influencing the SW Club was analyzed. And science core high school education plans, business plans and management reports were analyzed in SW club activities. It was the most influencing on the SW club in Creative-Experiential activities organization of computer courses. So computer curriculum reform is urgently needed. SW extra subject activities and funding was having a positive effect. Tuition reimbursement rates was having a negative effect. But academic achievement did not significantly affect. Therefore as many students as possible should be able to assist the SW extra subject activities. And it is required Programs and budget support that reflect the characteristics of local and school. Also, as science core high schools have STEAM education, science, mathematics and technology home economics teachers etc were leading the SW club activities by fusing the their curriculum and SW education. As these activities are consistent with the purpose of SW education, research should be more active autonomic consisting of various teachers.

This study analyzes elementary school teachers' perception of Artificial Intelligence, educational effect, and necessity in education. To analyze teachers' perceptions, we developed questionnaires with expert advice. We collected questionnaires for 151 elementary school teachers. The collected data were analyzed by t-test and one-way ANOVA. As a result, AI' perceptions of female teachers were lower than those of male teachers and the necessity of education was less. Teachers with experience in leading schools recognized that AI education would help to improve creativity. Teachers who have a lot of teaching experience, many experience in SW education, the experience in SW education have a high interest in AI and understand the relevance of the subject. We expect that this study will help the direction of SW education.

The purpose of this study is to analyze the perception of elementary and secondary parents on 'Informatics' education to solve the various social problems that can occur due to the application of mandatory 'Informatics' subject and find the stable public education settlement plans. For this purpose, we conducted and analysis of questionnaire survey on 'Informatics' education for parents of elementary and secondary students who participating the SW education camp in K university. The major results of this study are as follows. Firstly, both of elementary and secondary parents show high interest in the SW education policy of the government, but they are showing distrust about the timeliness of the actual SW education policy and the support of elementary and secondary education. Secondly, both of the elementary and secondary parents showed high awareness of the necessity and importance of 'Informatics' education and they recognized that 'Informatics' education should be done in high school. Thirdly, parents of elementary and secondary school students perceive that there is not enough time for 'Informatics' education and both of elementary and secondary parents to secure teachers with professional competence as a leading factor for stable settlement of 'Informatics' education in public education field. In this study, we suggested the stable settlement plans in public education field based on the analysis results.

Colon cancer is one of the most common malignancies in the western world and the second leading cause of cancer death in Korea. Epidemiology studies have shown a reduced incidence of colon cancer among populations consuming a large quantity of ${\omega}3$-polyunsaturated fatty acids (${\omega}3$-PUFA) of marine origin. Recently, it has been found that ${\omega}3$-PUFA has an antineoplastic effect in several cancers. This study was designed to investigate the mechanism of the anti-invasive effect of ${\omega}3$-PUFA in colon cancer. ${\omega}3$-PUFA, docosahexaenoic acids (DHA) and eicosapentaenoic acid (EPA) treatment resulted in a dose-dependent inhibition of cell growth in SW480 human colon cancer cells. In contrast, arachidonic acid (AA), a ${\omega}6$-PUFA, exhibited no significant effect. This action likely involves apoptosis, given that DHA treatment increased apoptotic cells in TUNEL assay. Moreover, invasiveness of SW480 cells was inhibited following treatment of DHA in a dose-dependent manner; in contrast, AA had no effect. The levels of MMP-9 and MMP-2 mRNA decreased after DHA pretreatment. MMP-9 and MMP-2 promoter activities were also inhibited by DHA treatment. The levels of NF-kB and p-IkB protein were down-regulated by DHA pretreatment in a dose dependent manner. In addition, DHA inhibited NF-kB promoter reporter activities. These findings suggest that ${\omega}3$-PUFA may inhibit cancer cell invasion by inhibition of MMPs via reduction of NF-kB in colon cancer. In conclusion, ${\omega}3$-PUFA could be used for chemoprevention and treatment of human colon cancer.

$A{\beta}_{40}$ peptides form oligomers that later aggregate into a plaque, which is deemed to be a leading cause of Alzheimer's Disease. Its non-crystalline morphology has limited an understanding of comprehensive structural study. In this research, computational biomolecular simulations were performed in the following order: solvent and ion addition in a box, energy minimization of protein, equilibration, and periodic boundary condition disaggregation of a monomer from fibril. The result founded the two-fold model is 25% more stable in the simulation environment, and the steric zippers held on most tightly until 220 ps of simulation. The study supports the previous findings that two-fold aggregate $A{\beta}_{40}$ is more stable at 310 K and discusses further how much contribution steric-zipper and hydrogen bonding are making.

In this paper, the information education plan of the Ministry of Education and offices of education was analyzed in relation to the construction of the AI convergence education room. And based on this, an appropriate construction direction was suggested. For research, AI convergence education room construction plan, budget amount per school and etc were analyzed in the information education plan of the Ministry of Education, KERIS, KOFAC, and the plan of leading schools for AI education. Although the Ministry of Education is making various efforts to promote SW education and artificial intelligence convergence education, it is found that the number is far insufficient compared to the number of elementary, middle and high schools. Efforts to expand the information education room at the government level are continuously required, and in order to utilize the developed artificial intelligence convergence education room, it is necessary to provide abundant teaching and learning examples for the construction space model. In addition, school-level planning and execution must be followed so that the constructed space can be used appropriately, and management and maintenance plans for equipment are required.
