This article is devoted to the study of the process of formation of the digital generation in a distance learning environment. With the introduction of quarantine due to the spread of COVID-19, opponents of digital technologies were forced to turn to relevant resources, while supporters identified new opportunities for the development of didactics and education in general. The irreversibility of the former educational reality became apparent and only the scale of the vision of potential change by interested and disinterested groups differed. Using a comprehensive approach, the authors consider the issues related to the direct and indirect impact of distance learning on children and young people born after the beginning of the XXI century. The article reveals the prerequisites and implications of distance education for the interaction of participants in the educational process. IC technologies during the educational process in the primary grades, in addition to identifying the student's learning deficit, should provide the transmission of non-verbal signals, which are important for children of this age. At the same time in the secondary school IR-technologies are designed to replace frontal learning during the assimilation of knowledge and at the same time not to worsen the quality of the educational process. Formation of students in the HEI takes place in the political science format, constant discussion of problem situations, so the task of introducing IC technology in this process is the accurate transfer of the content of the discussions. Individualization and autonomization of the educational process, its dependence on the results of the choice of educational content, and the use of pedagogical management tools change the philosophy of education for children and youth. The authors conclude that the formation of a digital generation, characterized by an increased level of digital literacy of children and youth, the possession of a certain level of digital capacity requires the use of strategies aimed at optimizing the learning process in a digital educational environment.

This paper proposes the new adaptive protection algorithm for inverse-time overcurrent relays (OCRs) to ensure their proper operating time and protective coordination. The application of the proposed algorithm requires digital protection relays with microcontroller and memory. The operating parameters of digital OCRs are adjusted based on the available data whenever system conditions (system with distributed generation (DG)) vary. Moreover, it can reduce the calculation time required to determine the operating parameters for achieving its purpose. To verify its effectiveness, several case studies are performed in time-domain simulation. The results show that the proposed adaptive protection algorithm can keep the proper operating time and provide the protective coordination time interval with fast response.

We studied the methods to utilize vehicle-based mobile mapping system for field investigation work of digital map generation process. Map layers which should be checked by field investigation were analyzed to find the possibility of being checked with data from vehicle-based mobile mapping system. Also new process for digital map generation were suggested to adopt field investigation by vehicle-based mobile mapping system. We performed field investigation work on the Kangneung area by vehicle-based mobile mapping on a trial bases and compared the results with a results from usual field investigation method.

Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

HSDPA(High Speed Downlink Packet Access) service has begun nationwide network service since the year 2007 and will be leading technology in mobile service technologies in domestic. But the ARPU(Average Revenue Per Use) from HSDPA has not increased, despite of increasing in subscribers with HSDPA service. It's important to understand why the incresing subscriber with hsdp didn't cause the increasing of its usage. The purpose of this study is to examine factors affecting the intention to adopt and to use HSDPA which refer to the new 3.5 generation communication service, and we are to analyze the relation between the two intentions based on previous studies about technology acceptance.

Digital surface model generation from IKONOS stereo imagery is a new challenge in photogrammetric community, especially when the satellite company does not provide the raw data as well as their ancillary ephemeris data. In this paper we utilized an estimated relief displacement azimuth and the nominal collection elevation data included in the metadata file to correct the relief displacement of GCPs, together with a linear transformation for geometric modeling of IKONOS imagery. Space intersection is performed by the trigonometric intersection assuming a parallel projection of IKONOS imagery due to its small FOV and frame size. In the experiment, less than 2-meters of RMSE in orbit modeling is achieved denoting the potential positioning accuracy of the IKONOS stereo imagery.

이 연구는 초고속 인터넷 환경에서 세계 최고 수준의 디지털 네이티브(digital native)세대를 형성하고 있는 한국적 현실에서 이들의 미디어 이용행태에 대한 종합적인 이해를 위해 시작됐으며, 미디어 동시이용행태에 대한 한국적 디지털 네이티브의 속성을 파악하고자 했다. 이를 위해 2015년도 <한국미디어패널> 데이터를 기반으로 디지털 네이티브 세대에 해당하는 10대 청소년들의 시간대에 따른 공간적 속성과 이용매체, 동시이용 형태 등에 대해 다중대응분석을 실시하였다. 연구결과 한국의 디지털 네이티브 세대라고 할 수 있는 10대 청소년의 경우, 시간적, 공간적 매체이용은 매우 균질한 형태를 띠고 있으며, 미디어 동시이용비율도 제한된 형태로 나타났다. 이 연구는 추후 다양한 세대 간 비교 연구를 통해 보다 총체적인 미디어 이용행태연구의 필요성을 제기하고 있다.

디지털 사이니지(Digital Signage)란 길가나 점포, 공공시설 등에 표시되어 있는 포스터나 안내표시, 간판 등 기존의 하드웨어 매체가 아닌 디지털 디스플레이를 통해 각종 콘텐츠와 메시지를 제공하는 옥외 미디어를 말한다. 최근 LCD, LED 등을 기반으로 하는 지능형 디지털 영상장치의 급속한 발전으로 디지털 사이니지(Digital Signage)는 보편화되고 있으며, 기존의 단방향 광고 매체가 아닌 쌍방향 의사소통이 가능한 특징으로 인해 디지털 사이니지에 대한 수요 및 시장은 급속한 성장을 보이고 있다. 디지털 광고시장은 전반적인 글로벌 경기침체에도 불구하고 지속적인 성장세를 보일것으로 전망하고 있으며, 융합(Convergence)미디어 관점에서도 간판이 디지털화됨에 따라 정보와 예술, 콘텐츠, 기업 마케팅 니즈가 결합되면서 점차 TV 등 기존 매체광고를 대체하는 새로운 수단으로서의 역할을 수행할 것으로 예상하고 있다.

Funology is a compound word with fun and technology which means the products or activity carrying fun and technology at the same time. This is one of the key words that can explain the culture of post-digital generation amongst the post-digital age. The purpose of this study was to provide the creative ideas to develop the fashion designs showing funology concept for the 21st century. As a background of funology trend, general ideas about the post-digital age and the post-digital generation were reviewed. First, funology designs among the industrial products and the funology concepts in the advertisement were examined. And the ways of expression and the meanings of funology fashion designs were extracted by analyzing funology fashion between 2000 S/S and 2008 F/W. The external expression ways of funology fashion in the post-digital age were as follows: parody of popular images, inharmony by the exaggeration or transformation, trompe l'oeil, mixture of the styles shown in the children's wear and the objects of children, patterns with childlike or animation characters, and the graffiti art. The internal meanings contained in the funology fashion were 1) fantasm showing surrealistic funology that was based on the people's pursue of fantasy free from the everyday's severe routine 2) memorism showing nostalgic funology that was based on the pursue of vanishing fear of reality and going back to the childhood. To sum up, fashions showing funology were expressed in various ways in the post-digital age. This will provide the great inspirations for creating the new coming fashions and efficient healing contents for the cold-hearted emotions of nowaday's people.
