The article examines the key constants of reengineering the modern educational cluster, associated with the processes of digital transformation of all spheres of modern socio-cultural space. The first constant is the strategic rethinking of the educational process organization and awareness of the new roles of all participants (tutors, applicants, controlling elements, etc.). The other constant involves practical re-design of the system of educational services, which consists in the reorientation from the traditional model of education functioning for society to the implementation of the educational format in the form of new projects (structural, target, business). Consequently, the purpose of the study is to highlight the attitudes relevant to the modern realities of information and technological support of education in the context of socio-economic interactions of society. The criteria for the reengineering of educational concepts and the structural organization of the educational sphere are defined. The modern world is going through a period of complete digital transformation of all spheres of public activity. The scientific intelligence notes that education is no exception in these processes, as the dependence of educational realities on information and computer technologies is now noted. The COVID-19 pandemic, for all its tragedy, was also a kind of trigger, clearly marking the new components that have become defined in the organization of the educational process. The conclusion is made that the use of digital technologies in the organization of the educational institution or in the organization of the educational process has become not an auxiliary element, but a dominant factor. Mobility, dynamism, interdisciplinarity, synergy - all these aspects are relevant for socio-economic interactions of society and should be provided by educational programs. The results of the study can be used in the reorganization processes of educational institutions and institutions. Further research requires aspects of the analysis of the foreign experience of reengineering in education, carried out taking into account digital transformations of modern sociocultural space.

The purpose of this paper is to design and implement the user motion pattern control system for the simulated vehicle. After analyzing the user motion patterns in the system, the patterns are used to control the moving direction of the simulated vehicle such as forward, backward, turn right, turn left etc. The patterns in the system around are sent to the simulated vehicle in real time. In order to execute the suggested user motion pattern control system, the Kinect is used for executing the system. The Kinect recognizes the specified user motion patterns and it transmits the data to the user motion pattern control system. There are nine kinds of the user motion patterns in the system for controlling the simulated vehicle. In addition to this, some sensors are used to detect the condition of the simulated vehicle. GPS is also used to estimate the current location of the simulated vehicle and to obtain the driving information.

7차 교육과정에서 추구하는 초등미술교육은 모든 학생이 화가가 되기를 바라는 것이 아니라 아름다움을 보고 느끼고 생활에 적용하여 보다 아름다운 생활을 가꾸어 갈 수 있는 심미적 인간을 기르고자 하는 것이다. 즉, 감상활동의 중요성이 나타나 있다고 할 수 있다. 그러나 교육현장 특히 학원가를 중심으로 감상영역 보다는 테크닉 위주의 학습이 행해지고 있는 것이 현실이며 도서 벽지의 학생들이 갤러리와 같은 물리적 공간에서 감상학습을 한다는 것은 더욱이 어렵고, 기존의 감상 자료들이 텍스트 기반으로 소수의 학생들만이 공유할 수 있다는 단점을 해결하고자 본 논문에서는 인간 감각 형태와 가장 비슷하다고 할 수 있는 웹 기반의 3차원적 학습 패턴을 기본으로 하는 갤러리 형태의 감상 학습 자료를 제공하는 시스템을 설계 및 구현하였다.

The distributed system is playing a vital role in storing and processing big data and data generation is speedily increasing from various sources every second. Hadoop has a scalable, and efficient distributed system supporting commodity hardware by combining different networks in the topographical locality. Node support in the Hadoop cluster is rapidly increasing in different versions which are facing difficulty to manage clusters. Hadoop does not provide Node management, adding and deletion node futures. Node identification in a cluster completely depends on DHCP servers which managing IP addresses, hostname based on the physical address (MAC) address of each Node. There is a scope to the hacker to theft the data using IP or Hostname and creating a disturbance in a distributed system by adding a malicious node, assigning duplicate IP. This paper proposing novel node management for the distributed system using DNA hiding and generating a unique key using a unique physical address (MAC) of each node and hostname. The proposed mechanism is providing better node management for the Hadoop cluster providing adding and deletion node mechanism by using limited computations and providing better node security from hackers. The main target of this paper is to propose an algorithm to implement Node information hiding in DNA sequences to increase and provide security to the node from hackers.

In this paper, human action recognition using pyramid histograms of oriented gradients and collaborative multi-task learning is proposed. First, we accumulate global activities and construct motion history image (MHI) for both RGB and depth channels respectively to encode the dynamics of one action in different modalities, and then different action descriptors are extracted from depth and RGB MHI to represent global textual and structural characteristics of these actions. Specially, average value in hierarchical block, GIST and pyramid histograms of oriented gradients descriptors are employed to represent human motion. To demonstrate the superiority of the proposed method, we evaluate them by KNN, SVM with linear and RBF kernels, SRC and CRC models on DHA dataset, the well-known dataset for human action recognition. Large scale experimental results show our descriptors are robust, stable and efficient, and outperform the state-of-the-art methods. In addition, we investigate the performance of our descriptors further by combining these descriptors on DHA dataset, and observe that the performances of combined descriptors are much better than just using only sole descriptor. With multimodal features, we also propose a collaborative multi-task learning method for model learning and inference based on transfer learning theory. The main contributions lie in four aspects: 1) the proposed encoding the scheme can filter the stationary part of human body and reduce noise interference; 2) different kind of features and models are assessed, and the neighbor gradients information and pyramid layers are very helpful for representing these actions; 3) The proposed model can fuse the features from different modalities regardless of the sensor types, the ranges of the value, and the dimensions of different features; 4) The latent common knowledge among different modalities can be discovered by transfer learning to boost the performance.

As the competition of 21 cyber universities in Korea has been on a continual increase, they are focusing on improving the quality of the e-learning education in cyber universities. In this study, we intended to derive the failure factors of the previous chatting system in the 2010s and the success factors from previous studies. Next, we identified priorities among five factors(Reliability, UI Convenience, Usability, Network effect, Operational policy) using AHP and the practical ways to implement the chatting service. We applied the chatting system to all the curriculums of S cyber university. Our study finds that the chat service affects the satisfaction of education. Finally, we propose the utilization plan to improve the e-learning education of cyber university through the findings of this research.

The article notes that one of the reasons for the crisis in education was the sharp discrepancy between the emerging new forms and content and the model of macro-management that has developed over the decades. The level of management of the educational system did not emerge as a specific activity characterized by its own mechanisms and processes, just as qualified carriers of this activity - professionals - managers - did not appear. At the same time, there is practically no theoretical and methodological model of the macrolevel of education management, that is, management of the educational system as an integral structure.

글로벌 시대의 요구에 부응하기 위해 교육 분야에서도 글로벌 교육에 대한 필요성과 중요성이 급증하고 있다. 하지만 보는 관점에 따라 글로벌 교육의 정의와 모델에 대한 합의가 아직 명확하지 않고 글로벌 교육 과정에서의 고비용성, 저효과성, 지속성 결여 등으로 인해 실제 글로벌 교육의 성과는 예상보다 기대에 미치지 못하고 있다. 더구나 예비 교원의 글로벌 능력을 함양하기 위한 글로벌 교육에 관한 연구는 거의 이루지지지 않고 있다. 본 연구는 예비 교원의 글로벌 교육을 중심으로 IT 융합 접근 방법을 연구하였다. 본 연구에서는 우선 국내에서 시행되고 있는 글로벌 교원 양성을 위한 글로벌 교육 프로그램을 비교 분석하였다. 또한, 글로벌 교육에서의 제약 사항들을 해결할 수 있는 IT 융합 교육 시스템을 연구하여 구체적인 IT 융합 글로벌 교육 방법들을 알아보았다. 특히 빅데이터 분석 기술을 기반으로 복수학위나 교환학생 프로그램에 도움을 줄 수 있는 글로벌 교육과정 이수 추천 시스템을 제시하였다.
