Data science is a discipline comprised of the academic fields of statistics, computer science, information technology, and domain knowledge. It analyzes data and derives meaningful results using complex technologies. Data science, along with artificial intelligence, is a core technology of the 4th industrial revolution; consequently, universities and companies worldwide are actively developing programs to develop data scientists who require high levels of expertise. In line with this undertaking, the field of elementary education has recognized the importance of data science education and so various studies have been conducted to develop curricula designed to help students understand how to use data. This paper proposes a curriculum for the purpose of educating elementary school teachers who are mostly non-majors in the computer field about data science. Satisfaction analysis was conducted based on questionnaires collected from students to analyze the effectiveness of the data science education proposed in this paper.

Based on the theory of local-world network, the composition self-similarity (CSS) of network traffic is presented for the first time in this paper for the study of DoS detection. We propose the concept of composition distribution graph and design the relative operations. The $(R/S)^d$ algorithm is designed for calculating the Hurst parameter. Based on composition distribution graph and Kullback Leibler (KL) divergence, we propose the composition self-similarity anomaly detection (CSSD) method for the detection of DoS attacks. We evaluate the effectiveness of the proposed method. Compared to other entropy based anomaly detection methods, our method is more accurate and with higher sensitivity in the detection of DoS attacks.

본 논문에서는 현재 웹의 주요한 기술로 부각되고 있는 액티브 서버페이지와 동적 웹 기술을 이용한 가상교육 시스템 구현에 대해서 다룬다. 이 시스템은 사용자로부터 프로그램 소스를 보호할 수 있고 또한 인터넷 서버에서 실행되는 액티브 서버 기술을 동적 웹 기술과 접목하여 사용자를 인지, 구별하고 사용자의 정보에 적합한 웹 페이지를 구성할 수 있다. 또한 가상교육시스템은 학년, 학과, 수강신청 정보에 따라서 적합한 사용자 환경을 구성하여 주고 수업진도에 따라 교안 및 정보를 제공할 수 있다. 이렇게 구성함으로써 시스템의 접속 사용자에 관련된 적합한 정보를 제공하여 사용자가 원하는 교육서비스를 받을 수 있게 한다.Abstract In this paper, we present our implementation of cyber education system using Dynamic Web and Active Server Pages, key technologies of the current web. This system is composed of web pages fitted to user information, which is collected and differentiated by both Active Server Technology running at server and protecting program source and Dynamic Web Technology. This system provides information and teaching content according to the progress of a course and user environments based on information such as a school year, a department and credit request information. Therefore login users can receive education services by providing adequate information related to them.

The purpose of this paper was to develop an instructional design model and checklist for AI education. Literature review was conducted to derive the structure of the instructional design model. And delphi survey was conducted twice to revise and improve the elements & items of the instructional design model and checklist and to confirm the content validity of both instructional design model and the checklist. As a result, an instructional design model consisting of three main steps(Analysis - Design & Development - Implementation & Evaluation) was suggested with a detail checklist which explained what teachers need to do in each step of this instructional development model when they prepare AI education using this instructional design model. Limitations and suggestions for further studies were presented at the end of this paper.

The purpose of this study was to develop an educational app that informs parents of elementary students with correct information on pesticide residue based on their awareness and information needs on pesticide residue. A survey was conducted from 918 parents living in 8 different districts of Korea. The results of the survey indicated that a majority of parents felt uncomfortable with pesticide residue and wanted to have the proper information regarding it. Based on the above results, an app named 'Perfect Conquest of Pesticide Residue' consisting of 5 main menus of 'Pesticide residue, Is it safe?', 'Safe management of pesticide residue', 'Perfect removal of pesticide residue on fruits and vegetables through washing', 'Shopping without anxiety', 'Playground' and their own sub-menus was developed. When the app was applied to 30 parents using smart phones, a majority of them were satisfied with the contents of detailed information and fun activities. Therefore, this app could be utilized as an effective educational tool for the parents of elementary students by allowing them to have proper awareness on pesticide residue. Furthermore, more apps could be developed on other food risk factors to promote safe dietary life.

This study, with teachers form elementary schools in Chungju-si as its subjects, has investigated influence of school forest on satisfaction with school greenspace and environmental education. It has reached the following conclusions. As for recognition of and satisfaction of school greenspace there were meaningful differences between teachers form school forest model schools and ones from common schools, which was thought to be due to positive effects of school forest movement. It appeared that environmental education was carried out through audio-visual materials once a week in most schools. On the other hand, as for class places, 'classroom in parallel with outdoor class' and 'classroom education' appeared to be carried out most frequently in the case of school forest model schools, and 'classroom education' in the case of common schools. However, considering the fact that 'field learning' the most important element in environmental education, appeared to be carried out least frequently in both of the groups, which suggests that we should improve it for future through introduction of various field-experience learning programs. As a result of the survey of satisfaction with environmental education, some meaningful differences were recognized between school forest schools and common schools, and 'presence or absence of field learning spaces' was the most frequently answered reason for 'satisfied' and 'unsatisfied'. Thus, 'schools' and related institutions' enthusiastic efforts are needed for providing field-experience spaces where children can directly access to and explore into nature.

This study aimed to investigate the effect of ladder-climbing exercise training on neurobiological markers in the hippocampus of mice with type 2 diabetes (T2DM). Twenty-one C57BL/6 male mice were randomly assigned to the non-diabetic control (NDC, n = 7), diabetic control (DC, n = 7), and diabetic training (DT, n = 7) groups. The DT group performed ladder-climbing training (LCT) five times a week for eight weeks. We measured the levels of hippocampal neurobiological markers (catalase [CAT], brain-derived neurotrophic factor [BDNF], nerve growth factor [NGF], amyloid-beta [Aβ], tau, and CC motif chemokine ligand 11 [CCL11]). The BDNF levels were significantly higher in the DT group than in the DC group (p < 0.05). The Aβ and CCL11 levels were significantly higher in the DC group than in the NDC and DT groups (p < 0.05). The tau levels were significantly higher in the DC group than in the NDC group (p < 0.05). However, there was no significant difference in CAT and NGF levels among the groups (p > 0.05). These results suggest that while T2DM could induce neurodegeneration, LCT may be effective in alleviating neurodegeneration caused by T2DM.

Around the world, public access to information plays a crucial role in improving lives and facilitating development. People, technology, and information, which also represent common themes of i-Schools, are deemed relevant in adapting to these global challenges. The main purpose of this research is to identify the orientation of curriculums in LIS Schools in South Korea toward technology, information, and people for graduate schools of library and information science. This research also correlates the directions of the schools with the UN 2030 Agenda. Using the Wilson model, this study examines the orientation of courses offered. The result of classification and content analysis revealed that courses offered are leaning towards technology and information content. Courses reviewed in the light of developing knowledge and skills of information professionals to facilitate the fulfillment of global goals can make libraries more responsive to the changing times.
