온라인 저지는 학습자가 제출한 소스의 컴파일과 실행, 문제 해결 여부에 대한 즉각적인 교정적 피드백을 제공하며 평가의 정확성과 신뢰성을 확보할 수 있지만, 대부분의 온라인 저지가 텍스트형 언어 만을 제공하고 있어 학습자의 수준에 따른 언어 선택이 어렵다. 본 연구에서는 온라인 저지용 블록형 언어를 개발하여 고등학교 수업에 적용하고, 블록형 언어 집단과 텍스트형 언어 집단 간 자기효능감의 차이를 확인하였다. 검정 결과, 블록형 언어 집단은 텍스트형 언어 집단 보다 '혐오경험극복 능력기대'가 더 높았고, 텍스트형 언어 집단은 사전-사후 검사에서 '활동시작 능력기대'와 '활동지속 능력기대'가 유의하게 감소된 것을 확인하였다. 이는 블록형 언어의 경우 차후 프로그래밍 활동에 대한 효능감에 효과가 있으며, 텍스트형 언어는 활동의 시작 단계와 진행 단계에서 학생의 자기효능감이 저하되지 않도록 하는 교수·학습 및 평가 방법을 강구해야 한다는 점을 함의한다. 본 연구는 고교 프로그래밍 수업에서 블록형 언어와 텍스트형 언어의 적용과 관련하여 자기 효능감 증진을 위한 교수·학습 설계의 기초를 제공한다는 점에서 의미가 있다.

Given the recent pace of development and expansion of Artificial Intelligence (AI) technology, the influence and ripple effects of AI technology on the whole of our lives will be very large and spread rapidly. The National Artificial Intelligence R&D Strategy, published in 2019, emphasizes the importance of artificial intelligence education for K-12 students. It also mentions STEM education, AI convergence curriculum, and budget for supporting the development of teaching materials and tools. However, it is necessary to create a new type of curriculum at a time when artificial intelligence curriculum has never existed before. With many attempts and discussions going very fast in all countries on almost the same starting line. Also, there is no suitable professor for K-12 students, and it is difficult to make K-12 students understand the concept of AI. In particular, it is difficult to teach elementary school students through professional programming in AI education. It is also difficult to learn tools that can teach AI concepts. In this paper, we propose an educational model for elementary school students to improve their understanding of AI through play or experience. This an experiential education model that combineds exploratory learning and discovery learning using multi-intelligence and the PLAY teaching-learning model to undertand the importance of data training or data required for AI education. This educational model is designed to learn how a computer that knows only binary numbers through UA recognizes images. Through code.org, students were trained to learn AI robots and configured to understand data bias like play. In addition, by learning images directly on a computer through TeachableMachine, a tool capable of supervised learning, to understand the concept of dataset, learning process, and accuracy, and proposed the process of AI inference.

This study is designed to grope for logical methods in the decision-making process of human beings such as creation and analysis. With this in mind, the paper worked with a process where the designers of a design team gather and analyze their opinions in a design process to decide on the HVAC system of buildings. The paper introduced the fuzzy theory, or one of the methods to quantitatively describe language values with ambiguous features, suggesting a method to determine the judgement and suggestion values of the HVAC designers with the characteristics of language variables as the values of design factors greatly influencing the HVAC system. As a result, the paper tested the possibility of the fuzzy system as a logical method to gather the judgement of HVAC designers in a stage of HVAC type selection exerting a great influence on the experience and judgement of the designers and having powerful linguistic features and to determine an appropriate HVAC type which can satisfy the suggested values of related design factors.

For Internet service providers (ISPs), there are three common types of interconnection agreements : private peering, public peering and transit. One of the most important problems for a single ISP is to determine which other ISPs to interconnect with, and under which agreements. The problem can be then to find a set of private peering providers, transit providers and Internet exchanges (IXs) when the following input data are assumed to be given : a set of BGP addresses with traffic demands, and a set of potential service providers (Private peering/transit providers and IXs) with routing information, cost functions and capacities. The objective is to minimize the total interconnection cost. We show that the problem is NP-hard, give a mixed-integer programming model, and propose a heuristic algorithm. Computational experience with a set of test instances shows the remarkable performance of the proposed algorithm of rapidly generating near-optimal solutions.

This paper introduces a clustering for Central Control System in New Distribution Automation System. There are three primary benefits to use clustering: improved availability, easier manageability and more cost-effective scalability. Availability: Clustering can automatically detect the failure of an application or server and quickly restart it on a surviving server. Clients only experience a momentary pause in service. Manageability: Clustering lets administrators quickly inspect the status of all cluster resources and easily move workload around onto different servers within a cluster. Scalability: Applications can use the Clustering services through the MSCS Application Programming Interface(API) to do dynamic load balancing and scale across multiple servers within a cluster.
