  • In spite of the rapid development of the public network, the variety of network-based developments currently raises numerous risks factors regarding copyright violation, the prohibition and distribution of digital media utilization, safe communication, and network security. Among these problems, multimedia data tend to increase in the distributed network environment. Hence, most image information has been transmitted in the form of digitalization. Therefore, the need for multimedia contents protection must be addressed. This paper is focused on possible solutions for multimedia contents security in the public network in order to prevent data modification by non-owners and to ensure safe communication in the distributed network environment. Accordingly, the Orthogonal Forward Wavelet Transform-based Scalable Digital Watermarking technique is proposed in this paper.

  • The ongoing COVID-19 pandemic once again demonstrated how crucial it is to have unlimited access to scientific information. At the same time, the economic disparities that the pandemic revealed and aggravated made us realize that many of us cannot afford access to expert knowledge. While the international community is speculating about possible outcomes of the crisis, one can be said for sure, the pandemic accelerated many inevitable changes that would otherwise happen at a slower pace including increasing digitalization of the society and the expanding role of open data in the life of the academic community.

  • In this paper, the power system automation based on CAN communication protocol is introduced. Along with digitalization of electrical device, the various on-line services such as remote control, remote monitoring, remote parameter setting, fault data recording and remote diagnostic have been realized and become available. Therefore, it is necessary for those electrical devices to have real-time and reliable communication protocols. Author proposes DNPC(Distributed Network Protocol with CAN) which is proper to the power system SCADA (Supervisory Control And Data Acquisition) and DCS (Distributed Control System). The physical and datalink layer of DNPC protocol consists of the CAN2.0B which has the real-time characteristics and powerful error control scheme. As the transport and application layer, DNP3.0 is adopted because of its flexibility and compatible feature. Using the DNPC protocol, the power system automation is realized.

  • 중국의 고대 문자인 "갑골문" 상형문자를 디지털과 결합시켜 대중화 시키는 것도 매우 의미 있는 일이라 사료된다. 표의문자 (表意文字) 인 중국 문자는 표음 문자 (表音文字) 인 한글과는 다르게, 보여 지는 시각효과가 크고 또 그 이미지화된 자료를 가지고 의미를 상고해 내는 작업을 함에 있어서 디지털의 기술을 빌려 쓴다면, 앞으로 중문학계는 물론이고 더 나아가 인문학계와 융합하는 문제는 시간문제라는 생각이 든다. 고대(상형) 문자를 컴퓨터과학, 즉 디지털과 결합시킨다는 것은 e-learing 의 기술적인 도입과 결합과도 상관이 있을 것 같은데, 앞으로 디지털 시대를 맞아하여 인문학과 자연과학과의 결합이 절실해 지리라 본다. 이를 위하여 e-learning 과 디지털 교육이 시급하며, 상형문자(표의문자)의 데이터베이스 구축 및 자료화 작업은 교육에 있어서도 매우 유용할 것이라 사료된다.

  • U-City 서비스로 대표되는 첨단 공간서비스는 그동안 10여년의 많은 노력과 예산투자의 결과로 가시화된 국토정보화(National Digitalization)의 결실로서 평가될 수 있다. U-City서비스는 정보통신기술을 근간으로 하고 있으나 현실공간의 지능화 측면에서 그 개념상 공간정보와 또 그것을 기반으로 국토공간을 분석하고 활용하기 위한 국토 공간계획과 긴밀한 연계관계를 갖지 않을 수 없다. 그러나 아직까지 U-City서비스는 기존의 공간정보 및 공간계획과 명확한 상호관계 설정 및 각 분야간 계획, 구축 및 관리간 연계가 미흡한 실정에 있다. 따라서 본 연구의 주요 목적은 디지털융합시대의 국토 유비쿼터스화라고 하는 큰 명제하에 U-City서비스가 국토 공간정보 및 공간계획과 상호 유기적 연계관계를 가지고 발전할 수 있도록 하기 위한 디지털융합공간(Digital Convergence Space)의 신개념을 제안하고 그 구현을 위한 제도적 정비방안을 제시하는데 있다.

  • Recently, various efforts have been tried in the construction industry to improve productivity by applying the fourth industrial revolution technology. Among the various technologies, researches for the automation and digitization of earthworks are being carried out steadily. As the interest in the benefits of digitalization of the earthwork field has increased, there have been more cases of technology development and application for digitalization of the earthwork field. However, there is not enough case study to present the analysis results of application cases. The purpose of this study is to verify the feasibility of applying the digitization technology of the earthwork in actual worksite. In order to digitize the worksite terrain, it is required the process of field measurement, measurement data registration, earthwork information input, and analysis cell generation. Particularly, it is possible to achieve information-enabled digitization rather than digitalizing only the shape through the input of the earthwork information and the analysis cell generation. By using the digital information of the earthwork field, it is possible to visually recognize the change of the earthwork field, so that it is expected to enhance the worker 's understanding and to be highly applicable to the management work. It is expected that the digital technology of earthwork site will be able to know the precise amount of volume change of the earthwork numerically, and it will be highly applicable to construction management.

  • Informatization of early childhood education in the EU occurs in the context of the use of ICT as a means of sharing experiences, practices in the education and training of preschool children, communication, both at the national level and locally - within educational institutions, as a means of document management, search, data processing and information for the management of early childhood educational institutions, and planning activities for these institutions. This article aims to identify the features of the informatization of early childhood education in EU countries. Results. The countries of the EU have different levels of workload on the staff of early childhood education institutions, which is caused by different numbers of preschoolers and workforce. The greatest load on the staff in France due to a large number of preschoolers, which, despite the reduction, remained the highest among all the countries. By comparison, Poland's significant workload is mitigated by the size of its workforce. With almost equal numbers of staff in Poland and Germany, the countries differ significantly in the number of preschoolers. The countries also have different funding mechanisms for early childhood education, which determines the potential for digitalization. In France, total spending on early childhood education has grown the least (by 11 % between 2012 and 2018), in Poland by 51 %, in the Czech Republic by 44 %, and in Germany by 49%. In France, 100 % is funded by the government, in Poland 78 % is funded by the government, in the Czech Republic and Germany 87 % and 85 % respectively is funded by the government. The results of the survey of teachers' training in the use of ICTs and the level of specialists' readiness to use them in their studies indicate a mismatch between education and the practice of using technology. At the same time, given the high level of professional training of teachers in the use of technology in education, a low level of practice of ICT use in teaching preschool children was revealed. Teachers require professional development of ICT skills.

  • The use of the Internet has become commonplace for billions of people on the planet. The rapid development of technology, in particular, mobile gadgets, has provided access to communication anywhere, anytime. At the same time, there are growing concerns about the behavior of people on the Internet, in particular, towards each other and social groups in general. This raises the issue of human rights in today's information society. In this study, we focused on human rights such as the right to privacy, confidentiality, freedom of expression, the right to be forgotten, etc. We point to some differences in this regard, in particular between the EU, etc. In addition, we describe the latest legal regulation in this aspect in European countries. Such methods as systemic, factual, formal and legal, to show the factors of formation and development of human rights in the context of digitalization were used. The authors indicate which of them deserve the most attention due to their prevalence and relevance. Thus, we concluded that the technological development of social communications has laid the groundwork for a legal settlement of privacy and opinion issues on the Internet. Simultaneously, jurisdictions address issues on every aspect of human rights on the Internet, based on previous norms, case law, and principles of law. It is concluded that human rights legislation on the Internet will continue to be actively developed to ensure a balance of private and public interests, safe online access and unimpeded access to it.

  • In the current context of digitalization of education, the use of modern methods and techniques of data analysis and processing in order to improve students' school results has a very important role. In our paper, we aimed to perform a comparative study of the classification performances of AdaBoost, SVM, Naive Bayes, Neural Network and kNN algorithms to classify the results obtained at the Baccalaureate by students from a college in Suceava, during 2012-2019. To evaluate the results we used the metrics: AUC, CA, F1, Precision and Recall. The AdaBoost algorithm achieves incredible performance for classifying the results into two categories: promoted / rejected. Next in terms of performance is Naive Bayes with a score of 0.999 for the AUC metric. The Neural Network and kNN algorithms obtain scores of 0.998 and 0.996 for AUC, respectively. SVM shows poorer performance with the score 0.987 for AUC. With the help of the HeatMap and DataTable visualization tools we identified possible correlations between classification results and some characteristics of data.
