Software Education will be implemented at elementary, middle and high schools starting in 2018. The goal of software education is to help students develop Computational thinking skills. Computational thinking is largely composed of abstraction and automation. However, the concepts related to abstraction are defined differently for each country, giving confusion to students and teachers. Therefore, in this paper several definitions of abstraction are compared and defined reasonably. And we proposed an abstraction teaching method and evaluation criteria in elementary school based on a reasonable definition. The definition of abstraction presented in this paper is expected to be able to present a solution to the problems encountered in the course of software education in the future.

Purpose This study explores the development direction of the artificial intelligence curriculum as a universal education that enhances the ability of college students to flexibly use artificial intelligence these days, where artificial intelligence education is spreading, and the educational components based on this are subdivided according to the characteristics of each major. Design/methodology/approach In order to develop the educational purpose of the subject and the detailed educational curriculum suitable for the subject of education, we first analyzed domestic and foreign prior research related to artificial intelligence liberal arts education. As the main components derived by experts, the basic concept of artificial intelligence converges to literacy to read and write for everyday problem solving, as well as problem-solving ability to manipulate real data and software. Findings The results showed that In the artificial intelligence literacy module, trends and prospects of artificial intelligence and necessary competencies were checked, and cases applied to major fields were examined. In the AI utilization and application part, basic data analysis items and content composition were composed through creative thinking, logical thinking, and intelligence. In order to design the curriculum, a software development language suitable for each major area was first selected, and AI education content areas, elements, and packages were defined and designed for each major area to meet the objectives of the subject.

Interest in AI and SW education is growing as digital literacy is emphasized in the revised elementary school curriculum for 2022. There are numerous restrictions on how pupils can enhance their digital literacy because there are only 34 class hours available for information education in elementary schools. Therefore, other subjects and information education must be blended in order to ensure class hours for AI and SW instruction. In this study, we investigated the impact of S-PUMA reading instruction on the literary imagination and computational thinking of elementary school pupils. To conduct this study, two classes of sixth graders in an elementary school were chosen and split into an experimental group and a control group. Over the course of five sessions, only the experimental group received reading instruction using the S-PUMA teaching approach. It was discovered that reading instruction with the S-PUMA teaching methodology enhanced literary imagination and computational thinking. Further study is required to identify whether the improvement in creative imagination, a component of literary imagination, is a result of the S-PUMA teaching approach or a natural result of the subject matter of the lesson.

Recently, a new theoretical and methodological approach for computational science is becoming more and more popular for analyzing and solving scientific problems in various scientific disciplines such as Computational fluid dynamics, Chemistry, Physics, Structural Dynamics, Computational Design and applied research. Computational science is a field of study concerned with constructing mathematical models and quantitative analysis techniques and using large computing resources to solve the problems which are difficult to approach in a physical experimentally. In this paper, we present R&D of EDISON open integration platform that allows anyone like professors, researchers, industrial workers, students etc to upload their advanced research result such as simulation SW to use and share based on the cyber infrastructure of supercomputer and network. EDISON platform, which consists of 3 tiers (EDISON application framework, EDISON middleware, and EDISON infra resources) provides Web portal for education and research in 5 areas (CFD, Chemistry, Physics, Structural Dynamics, Computational Design) and user service.

This paper focuses on a differentiation strategy to improve educational competitiveness of education department. The reason is that education department stand now on the brink of a precipice because of low employment rate. For this, I researched on 'employment rate' and 'curriculum nature' of educational technology department of YW university and A university, lifelong education department of S university and D university, educational psychology department of SW university which are all related to pedagogy relation department recording relatively high-employment rate. Through the date, I'd like to emphasize that competitiveness of education department depends on a differentiation strategy and that strategy must be based on the influence of education with the consideration of obligation and characterization. And we find that a influence of education can be demonstrated in two aspects : a rational scheme's side and lively culture's side. In the rational scheme aspects, diversification and specialization of curriculum content considering department characteristics and curriculum management including mentoring and sense of realism are emphasized. On the side of culture scheme, positive involvement of members, outlook on the world defined by the concepts like challenge and passion to the future, a sense of community. These discussions will be a guide role on the future researches which focuses on improving competitiveness of education department.

As the interest in Education for Sustainable Development (ESD) increases worldwide in and around UNESCO, the aids for IT equipment and the donations for educations to developing countries are being active. Through Powerpoint-based teaching and learning contents simply authored by teachers, Mischief can be used to help many children in self-driven class activities. In this paper, we developed an additional program to control mouse pointers of Mischief with image files, size, and speed factors. Then we applied them to elementary students for enhancing their interest and participation to class activities.

Wavelet scheme can be applied to the various remote sensing problems: conventional multi-resolution image analysis, compression of large image sets, fusion of heterogeneous sensor image and segmentation of features. In this study, we attempted wavelet-based filtering and its analysis. Traditionally, statistical methods and adaptive filter are used to manipulate noises in the image processing procedure. While we tried to filter random noise from optical image and radar image using Discrete Wavelet Transform (DW1) and Stationary Wavelet Transform (SW1) and compared with existing methods such as median filter and adaptive filter. In result, SWT preserved boundaries and reduced noises most effectively. If appropriate thresholds are used, wavelet filtering will be applied to detect road boundaries, buildings, cars and other complex features from high-resolution imagery in an urban environment as well as noise filtering

In this paper, we propose a simple and efficient retrieval technique using the feature value of the corner region, which is one of the shape information attributes of images. The proposed algorithm extracts the edges and corner points of the image and rearranges the feature values of the corner regions doubly, and then measures the similarity with the image in the database using the correlation of these feature values as the feature vector. The proposed algorithm is confirmed to be more robust to rotation and size change than the conventional image retrieval method using the corner point.
