Recently, unmanned terminals (kiosks) have greatly increased their scope of use by allowing orders or payments to be made efficiently while replacing existing manpower. With the acceleration of digital transformation, the rate of kiosk installations has soared, making it an important task to help all age groups easily use kiosks. In this study, based on the function of the game engine and Hand Tracking technology, we developed content that can conduct kiosk education in a virtual world. The goal of this content is to help users unfamiliar with kiosks confidently cope with real-world situations by experiencing visual and auditory stress caused by waiting guests in virtual reality. To this end, two VR contents were developed. One is a simple kiosk experience content, and the other is specialized content that causes visual and auditory stress. The experiment was divided into two groups: one group experienced general VR content, while the other group experienced specialized VR content. After the experience, both groups proceeded to place orders in an actual store. Survey results showed that 85% of the experimental group and 95% of the control group were satisfied with the training. This confirms that the specialized experience described in this paper is effective for kiosk education.

Software productivity doesn't satisfy the need of service of software users and software quality isn't improved. Moreover, we still have difficulty in software maintenance. As a plan to counteract solving this crisis, the technology that is called CBSE or Componentware is introduced. Componet Based Software Architecture, one of the technologies associated with CBSE, as a structural description of system, describes both the components composed system of and interaction among these components. Software Architecture provides the technology and the methodology of composition among components in the field of CBSE. is accepted one of core technologies. In this thesis, we analyse information necessary for component specification and then proposed that component specificaton activities using formal specification language Z which is verified with the ability of analysis and logicality. The proposed activities are composed of 9 tasks. By presenting specific 11 products, it is also proposed that component specification activities which is the base of CBSD(ComponentBased Software Development) for reusing.

Although computer technology has a great potential for improving mathematics learning practice, it rarely used in mathematics classroom. The purpose of this study is to suggest the future direction for research in mathematics computer technology. First, there has to be a research on mathematics curriculum that take computer technology into account. Second, research on teaching sequence for certain content area is needed. Because computer technology would change the order of teaching sequence. Third, how students would learn with computer technology? how do they acquire knowledge and make sense of it? Fourth, how could we assess the learning with computer technology? Most of all, because teachers play a key role to succeed in educational reform, they have to be familiar with computer technology and software to introduce it into mathematics learning and to use it properly.

The purpose of this study are (1) to analysis the Paradigm’s changes in Educational Technology, (2) to examine its practice in Home Economics Education (H.E.E.), especially the researches about CAI in H.E.E. and (3) to propose the ideal practice of Educational Technology in H.E.E. As results, the paradigms of Educational Technology have been changed from media-centered to human-centered, and from objectivism(behaviorism and cognitivism) to constructivism. Related on Educational Technology, there have been six conceptual distortions or confusions in H.E.E. The Analyzed seven previous works on CAI in H.E.E. show the traditions of the Objectivism. And suggestions for ideal practice of Educational Technology in H.E.E. are presented.

우리의 교육은 다양한 매체의 등장과 기술의 발달로 인해 이러닝, 모바일 러닝, 소셜 러닝, 스마트 러닝에 이르기까지 다양한 방식으로 발전 하고 있다. 빠르게 변화하는 교육환경 속에서 우리가 지금 해야 하는 것은 기술의 발전이 가져다준 미래지향적인 교육 패러다임의 방향을 알고, 교육 현장에 적용하는 것이다. 스마트 시대에 적합한 학습환경을 마련하기 위해서는 이러닝의 주요 학습 환경 구성요소인 학습관리시스템(LMS: Learning Management Systems)의 변화가 매우 중요한 역할을 담당한다. 국내 외 이러닝 분야의 표준은 빠르게 신규 버전이 개발되고 새로운 영역의 표준들이 등장하고 있다. 본 논문에서는 디지털 콘텐츠 및 출판의 융합모델에 대한 표준으로 급부상중인 IMS의 Common Cartridge를 기반으로 하는 수준별 오답분석 시스템을 설계하였다.

빅데이터의 중요성이 부각되고 있는 빅데이터의 시대에 교육서비스시장은 스마트 교육이라는 새로운 변화에 따라 많은 변화가 일어나고 있다. 자기 주도적이며 개인화되고 쌍방향커뮤니케이션 등의 특징을 가진 스마트러닝 환경에서는 LMS와 LCMS의 역할이 점점 중요해지고 있다. 현재 콘텐츠의 중요성이 부각되는 정보홍수 시대이므로 LCMS가 해야 할 역할이 크다. 그러나 아직까지는 교육서비스에서 빅데이터의 아키텍쳐와 대용량 데이터 처리 기술을 활용하고 있는 사례는 그다지 많지 않다. 이에 본 논문에서는 빅데이터 기술을 활용한 LCMS에 대해 분석하고 새로운 방안을 제시하고자 한다.

Confronted with serious problems in nurturing IT engineers such as a mismatch in supply and demand of IT workers, shortage of globally competitive IT professionals, and insufficient education and training of university graduates, the Ministry of Information and Communication has decided to adopt a new approach in national IT engineering education, based on supply chain management (SCM) in manufacturing. SCM weighs improving competitiveness of the supply chain as a whole via a long-term commitment to supply chain relationships and a cooperative, integrated approach to business processes. These benefits of SCM are believed to provide useful insight into a more effective IT education and industry orientation. On the basis of the SCM literature, a framework for industry-oriented practical IT higher education is designed, and then applied in the field of computer-software engineering in Korea.

Artificial intelligence clouds help to efficiently develop the autonomous things integrating artificial intelligence technologies and control technologies by sharing the learned models and providing the execution environments. The existing autonomous things development technologies only take into account for the accuracy of artificial intelligence models at the cost of the increment of the complexity of the models including the raise up of the number of the hidden layers and the kernels, and they consequently require a large amount of computation. Since resource-constrained computing environments, could not provide sufficient computing resources for the complex models, they make the autonomous things violate time criticality. In this paper, we propose a digital twin software development framework that selects artificial intelligence models optimized for the computing environments. The proposed framework uses a load estimation DNN model to select the optimal model for the specific computing environments by predicting the load of the artificial intelligence models with digital twin data so that the proposed framework develops the control software. The proposed load estimation DNN model shows up to 20% of error rate compared to the formula-based load estimation scheme by means of the representative CNN models based experiments.
