Problem Statement: Regardless of the significant increase in the use of digital libraries during the Covid-19 pandemic, distribution of its publications has not been mapped as a form of scientific communication. Purpose: Therefore, this research aims to describe and map the information on digital libraries during the pandemic on international publications Scopus indexed. Method: The bibliometric assessment method was used to collect data from 66 publications on the Scopus database. The writer simultaneously used search keywords such as “Digital Library,” “Electronic Library,” and “Covid-19” to determine the publications from January 2020-June 2021. Results: The result showed that 23 (34.8%) out of 66 publications had high relevance to digital libraries during the pandemic, while 74% are scientific journal articles. The country with the largest contribution is the USA, while the largest publisher with only 35% open publications is Emerald. Meanwhile, the central topics in this research map include “Pandemic”, “Covid”, “Library”, and “Services”. Conclusion: The distribution of publications as a form of academic communication has not intertwined, as indicated by the absence of linkage between each author, thereby creating a high potential for studies and publications related to this topic. In addition to increasing the digital literacy of librarians and users, the transformation to high-tech virtual and digital services also stands as an adaptation effort.

As informações armazenadas nos sistemas corporativos são, geralmente, desconhecidas pela maioria dos membros de uma organização. Muitas vezes a informação necessária está disponível, mas as pessoas não sabem como acessá-la e nem da sua existência. Diante desta incógnita, tratou-se a seguinte questão: como identificar as informações de uma organização a partir dos seus sistemas de informação? Para resolvê-la, realizou-se uma pesquisa qualitativa, metodológica e documental, visando definir um mapa das informações armazenadas em sistemas de informação corporativos da Embrapa. Para a construção do mapa, definiu-se um processo para sistematizar o mapeamento das informações. O processo baseou-se em conceitos da arquitetura da informação, de representação por meio de metadados, de classificação das informações e de correlação com os processos de negócio da empresa. A aplicação do processo proposto foi feita em três sistemas corporativos da Embrapa. Foram analisados sessenta e três relatórios para a construção do mapa de informação. Foi possível responder às seguintes questões: quais informações estão duplicadas na organização e onde elas estão; quais relatórios têm excesso de informações; quem pode ter acesso a determinada informação; quais são os processos de negócios apoiados por determinado sistema de informação. Concluiu-se que apenas a consulta disponível em sistemas informatizados não é suficiente para ter acesso à informação. A construção de um mapa de informações permite facilitar a localização e o acesso às informações armazenadas nos diversos sistemas corporativos. Information stored in computer systems are, generally, unknown by most of the members of an organization. Frequently, information needed is available, but people do not know how to access it and about its existence. Having that issue in mind, the following question was posed: how to identify an organization information in its information systems? To answer it, a qualitative, methodological and documental research was carried out to define a map of the information stored in the corporate information systems of Embrapa (Brazilian Agricultural Research Corporation). To build the map, a process to systemize the mapping of information was created. The process was based on information architecture concepts, metadata representation, classification of information and relationship with the enterprise business process. The proposed process was applied in three corporate systems of Embrapa. To create the information mapping, sixty three reports were analyzed. Using the map some answers could be answered to improve the decisions, such as: "what information are duplicated in the organization and where are they?"; "which reports have much information?"; "who can access some information?"; "which are the business processes supported by an information system?" It can be concluded that queries available on information systems are not enough to have access to information. An information map facilitates localization and access to the information stored on different corporate systems.

Introduction. Requirements for the quality of information about the trajectory of moving objects provided by sensor networks are increasingly becoming more stringent. For Information and Data Processing Centers (DPC) at control and management command posts, the issue of information mapping and forming the true trajectories of moving objects in the area of intersection of network detection zones is of particular importance. The use of conventional approaches to solving this problem involves issues related to ensuring the efficient provision of users with complete and reliable information about trajectories in real time. In this article, wee propose a new approach to solving this problem using data mining theory, in particular, the methods of data clustering theory. Based on an analysis of the process of processing radar data in a DPC and its similarity with that of data clustering, we synthesized an algorithm for processing the trajectories of moving objects. The algorithm was verified by modelling and experimental research.Aim. To develop a generalized scheme for processing object trajectories (TP) in a DPC and to synthesized a TP algorithm using the methods of data clustering theory.Materials and methods. Data Clustering theory, Systems Engineering theory, Radar Data processing theory (RD), methods of mathematical modelling and experimental research.Results. Based on an analysis of the essence of radar data processing (RD) in a DPC and its similarity with the process of data clustering, an algorithm for processing the trajectories of moving objects was synthesized and verified by modelling and experimental research. A generalized scheme for processing the trajectories of moving objects in a DPC and a TP algorithm for a DPC were synthesized.Conclusions. An algorithm for processing object trajectories was proposed based on a new approach of data clustering theory. A generalized scheme and an algorithm for processing object trajectories (TP) in a DPC were suggested. These developments can be effectively applied in various models, e.g. centralized, hierarchical and decentralized. The synthesized algorithm can provide output information about the true identified trajectories in terms of various indicators of data processing systems (DPS).

The recent use of geographic information systems (GIS) to visualize large historical datasets are particularly useful to History instructors who seek real-world platforms that support an open-ended investigation of past societies. The University of Toronto’s DECIMA Project (Digitally Encoded Census and Information Mapping Archive) presents an open-access platform through which anyone can explore census material collected in early modern Florence. This article explores how senior undergraduate students used the DECIMA Project to construct research-based learning assignments that they developed independently. A rubric assessed the resulting student work in order to evaluate several cognitive abilities that students employed during their method design, data analysis, and the contextualization of conclusions. The assignment also drew on central History disciplinary concepts (articulating a question, constructing an argument, evaluating sources, and discerning challenges to the narrative), while introducing students to 'real Florentines.'

This paper is the initial discussion of a larger project Tattoo and Information, exploring tattoos as an information and communication phenomenon from multicultural perspectives and various use purposes. The overall purpose of the project is to provide insight into information seeking and experience in the context of tattoos to identify information literacy, visual literacy and cultural literacy skills as well as communications skills necessary for a successful tattoo experience in Aotearoa New Zealand. In this paper, we present findings from the literature review accompanied by preliminary insights from four interviews. The findings reflect thematic areas of research focusing on tattoos and gaps that exist. We used interviews to capture what topics emerge from tattoo narratives and whether they align with topics and gaps identified in the literature review. Based on the findings, we identify areas for future research.

This paper presents a method for the transparent, robust, and highly capacitive watermarking of video signals using an information mapper. The proposed architecture is based on the use of deep neural networks to embed the watermark in the luminance channel in the YUV color space. An information mapper was used to enable the transformation of a multi-bit binary signature of varying capacitance reflecting the entropy measure of the system into a watermark embedded in the signal frame. To confirm the effectiveness of the method, tests were carried out for video frames with a resolution of 256 × 256 pixels, with a watermark capacity of 4 to 16,384 bits. Transparency metrics (SSIM and PSNR) and a robustness metric—the bit error rate (BER)—were used to assess the performance of the algorithms.

Recently, the concept of spatial and direction modulation (SDM) has been developed to reap the advantages of both spatial modulation (SM) and directional modulation (DM). On the one hand, DM ensures the transmission security at the expected direction. On the other hand, the structure of SM-aided distributed receivers can enhance the security even if the eavesdropper is located in the same direction as the legitimate receiver. However, the above advantages are achieved based on the assumption that the eavesdropper is not equipped with distributed receivers. On the other hand, the information security can no longer be guaranteed when the eavesdropper is also equipped with distributed receivers. To alleviate this problem, we considered a joint design of SDM and covert information mapping (CIM) in order to conceive of a more robust structure of CIM-SDM. Furthermore, both the detection performances at the eavesdropper and the legitimate user were quantified through theoretical derivation. In general, both the analysis and simulation results supported that the proposed CIM-SDM structure provides more robust secure performance compared to the original SDM, even if the extreme condition of distributed receivers at the eavesdropper is considered, at the cost of moderate performance loss at the legitimate user.

This work proposes a model for the application of cartographic and geographic information mapping methods to systematize environmental monitoring data. In particular, based on the results of sampling and study of biological material (roach, Rutilus rutilus (Cyprinidae, Cypriniformes)) from the Angara River system, we obtained an array of information this could be processed and organized on its basis by means of a cartographic presentation of research materials on the state of the environment of water bodies in the Irkutsk region.

The Global Islamic Calendar doesn't yet exist because it cannot be applied in some Muslim countries in the world. The criteria for Global Islamic Calendar still debated because it’s difficult to apply throughout the world. The development of information technology encouraged astronomers to digitize the site-based global Islamic calendar. Some websites that we have researched have not yet used the integrated calendar criteria set in Turkey Congress 2016. Therefore it is necessary to maping a website that presents a global Islamic calendar so that it can be used as a reference recommendation for Muslim community.

Este artigo apresenta, sob o ponto de vista do Design da Informação, uma análise comparativa a partir da representação gráfica de um projeto de pesquisa através do mapeamento de informação de Robert Horn (1993) e das ferramentas gráficas de Yvonne Hansen (1999). O objetivo deste artigo é comparar a representação de um projeto de pesquisa a partir do estudo das ferramentas propostas por estes autores. A metodologia adotada se baseia na pesquisa bibliográfica como principal procedimento técnico e a partir desta prática se propõe a analisar comparativamente as duas ferramentas trabalhadas. Como resultados, notou-se que o mapeamento de informação de Horn não é eficiente na fase inicial do estudo do problema, mas é útil quando é necessário organizar as informações; e que as ferramentas gráficas de Hansen podem ser usadas no processo inicial de especificação de um problema porque são eficientes na clarificação de ideias e compreensão de conceitos.

Resumen El propósito del presente estudio consiste en caracterizar el material bibliográfico que se ha generado en el escenario mundial sobre la identidad ambiental. Como delimitación temporal se tomaron los últimos 18 años de producción académica presente en bases de datos de alto impacto, a partir del mapeamiento informacional bibliográfico. Para cumplir con este objetivo, se parte de la formulación de dos preguntas de investigación: ¿cuál es la producción científica (artículos) relacionada con investigaciones sobre identidad ambiental?, ¿a qué campos o áreas pertenecen las investigaciones sobre identidad ambiental y qué categorías emergen? Los resultados muestran que más del 50 % de la literatura sobre identidad ambiental se concentra en dos países (Estados Unidos y Reino Unido) y que en el análisis emergen ocho campos o áreas de conocimiento en los que la identidad ambiental supone un sentido de conexión con la naturaleza, lo cual involucra habilidades, actitudes y valores que emergen en la relación con los otros. Abstract The purpose of this study is to characterize the literature that is being built on the world stage on environmental identity, taking as a timeline the academic production of the last 18 years in high impact databases. To fulfill this objective, we start with the formulation of two research questions: What is the scientific production (articles) related to research on environmental identity? What fields or areas have addressed research on environmental identity and what categories emerge? The results show that more than 50% of the literature on environmental identity is concentrated in two countries (the United States and the United Kingdom) and that in the analysis there are eight fields and/or areas of knowledge where environmental identity implies a sense of connection with nature, which involves skills, attitudes and values that emerge in the relationship with others.

Acquisition of accurate archaeological heritage data is fundamental for the prospective steps of architectural conservation process. As of today, digital data capturing technologies such as image-based and range-based systems are rapidly becoming prevalent and generating digital surface representations of the object(s) in the form of three-dimensional point clouds. Point clouds assist heritage experts to carry out heritage analysis in digital forms, in particular to conduct condition assessment based on orthophotos of archaeological assets. In this paper, we introduce an integrated strategy by using Terrestrial Laser Scanning (TLS) and photogrammetry for the scope of obtaining orthophotos as basis for analyzing geometric, texture and color information of archaeological remains. Such a combination allows overcoming insufficiencies especially in terms of color due to the high natural light exposure. To remedy such visual obstacles, this paper demonstrates results to generate maximum visual data coverage of an archaeological heritage asset for the conservation process.&nbsp

Como procedimentos metodológicos, utilizou-se cinco etapas. A primeira consistiu em uma Revisão Bibliográfica, com levantamento na literatura na Ciência da Informação, com conceitos ligados à Gestão do Conhecimento, às Tecnologias de Informação na Sociedade do Conhecimento, a Mapas Conceituais, ao Ciclo de Vida dos Dados, à caracterização do ambiente de pesquisa, à Unidade de Recursos Humanos e ao Sistema Integrado de Gestão Unidade de Recursos Humanos do Centro Paula Souza, a qual pôde-se compreender aspectos relevantes à pesquisa e ao ambiente organizacional escolhido em verificar a gestão, a mediação e o uso da informação. Na segunda etapa, adotou-se como método o Estudo de Caso único, tendo como Universo de Pesquisa a Etec Antonio Devisate, situada em Marília, estado de São Paulo. Como sujeitos teve-se a Diretoria de Serviços Administrativa e a Direção. Os Referenciados foram os docentes. Como instrumentos para coleta de dados, optou-se pela utilização de entrevistas estruturadas, questionários e o acesso às informações disponíveis na plataforma online. Na terceira etapa, utilizou-se a triangulação como técnica de análise dos dados, no tratamento da pesquisa qualiquantitativa. Foram avaliadas as formações de 22 docentes da instituição, do eixo Gestão e Negócios, que resultou no mapeamento das informações tratadas por meio de tabelas e do Modelo Conceitual perfazendo a quarta e quinta etapas. Mediante as análises efetuadas, pôde-se verificar com êxito os dados obtidos com a construção do modelo conceitual da pesquisa, com temas articulados e requeridos ao perfil e à formação técnica profissional do Centro Paula Souza, tendo a formação contínua docente como papel relevante na sociedade do conhecimento. Concluiu-se, portanto, que os estudos voltados à Ciência da Informação no contexto educacional podem colaborar com o fortalecimento e crescimento da equipe de trabalho em um ambiente organizacional. The present research has as general objective the elaboration of a conceptual model of the competences of the continuous formation of the teachers of the Technical School Antonio Devisate, maintained by the State Center of Technological Education Paula Souza, with the use of an online data platform called Integrated System Management of the Human Resources Unit. As methodological procedures, five stages were used. The first consisted of a Bibliographic Review, with a survey of the literature in Information Science, with concepts related to Knowledge Management, Information Technologies in the Knowledge Society, Concept Maps, the Data Life Cycle, the characterization of the research, the Human Resources Unit and the Integrated Management System Human Resources Unit of the Paula Souza Center, which could understand aspects relevant to the research and the organizational environment chosen to verify the management, mediation and use of information. In the second stage, the single case study method was adopted, with Etec Antonio Devisate, located in Marília, state of São Paulo, as the Research Universe. As subjects there was the Administrative Services Directorate and the Direction. The Referees were the teachers. As instruments for data collection, it was decided to use structured interviews, questionnaires and access to information available on the online platform. In the third stage, triangulation was used as a data analysis technique, in the treatment of qualitative and quantitative research. The training of 22 faculty members of the institution, of the Management and Business axis, was evaluated, which resulted in the mapping of the information treated through tables and the Conceptual Model, comprising the fourth and fifth stages. Through the analyzes carried out, it was possible to verify successfully the data obtained with the construction of the conceptual model of the research, with articulated and required themes to the profile and to the professional technical training of the Paula Souza Center, with the continuous teacher training as a relevant role in society of knowledge. It was concluded, therefore, that studies focused on Information Science in the educational context can collaborate with the strengthening and growth of the work team in an organizational environment.

As a widely recognized policy language of access control, the eXtensible Access Control Markup Language (XACML) is widely used with its fine-grained and easy-to-read. With the application of XACML, researchers find that the XACML based policy evaluation and policy management methods can no longer meet the current large-scale requests for efficient access and dynamic management requirements. To improve the performance of policy evaluation based on XACML, we propose a policy evaluation method based on the matching tree to search policy efficiently and avoid the extra consumption of invalid policy participation. Furthermore, we propose a policy dynamic management method based on the matching tree to reduce the scale of the policy to be disabled for management, by adding locks in the tree node and the information mapping table. Through theoretical derivation and the factors that may affect its evaluation performance, we verify the improvement of evaluation efficiency. The simulation also shows the improvement of the evaluation engine based on the matching tree compared with OuenAz.

With the rapid development of artificial intelligence and the Internet of Things technology, the demand for concealment of data and information is increasingly strong, and information hiding technology plays a key role in information security. At present, there are some problems in the generative steganography mechanism based on deep learning, such as low quality of generative steganography and weak anti-steganographic analysis ability. In view of the above problem, this paper proposes a Realness-DCGAN based information hiding mechanism, this mechanism will secret information mapping division and the noise vector generator, according to the noise generated vector containing the secret image by using fidelity distribution as a standard of judging output, constraint generator to generate a higher quality of the secret image, finally using an extractor to extract the secret information. Experiments show that compared with the traditional steganography mechanism based on deep learning, the information hiding mechanism proposed in this paper by embedding RealnessGAN into the traditional DCGAN can significantly improve the quality of generated images containing secrets, and improve the accuracy and security of information extraction.

Hand-tracking has been advertised as a natural means to engage with a virtual environment that also enhances the feeling of presence in and lowers the barriers to entry to virtual reality. We seek to explore combining hand-tracking with voice input (which is then processed with automatic speech recognition) for a novel multimodal experience. Thus, we created Let's Go There, which explores this joint-input method for four functions in virtual reality environments: positioning, object identification, information mapping, and disambiguation. This combination may serve as a more intuitive means for users to communicate and navigate in virtual environments. We expect there to be multiple potential applications of this multimodal form of interaction across numerous domains including training, education, teamwork, and games. Let's Go There, the system described in this paper, was first accepted at CUI 2020, however we also believe there is value in showcasing it at MobileHCI.

Heritage recording has received much attention and benefits from recent developments in the field of range and imaging sensors. While these methods have often been viewed as two different methodologies, data integration can achieve different products, which are not always found in a single technique. Data integration in this paper can be divided into two levels: laser scanner data aided by photogrammetry and photogrammetry aided by scanner data. At the first level, superior radiometric information, mobility and accessibility of imagery can be actively used to add texture information and allow for new possibilities in terms of data interpretation and completeness of complex site documentation. In the second level, true orthophoto is generated based on laser data, the results are rectified images with a uniform scale representing all objects at their planimetric position. The proposed approaches enable flexible data fusion and allow images to be taken at an optimum time and position for radiometric information. Data fusion usually involves serious distortions in the form of a double mapping of occluded objects that affect the product quality. In order to enhance the efficiency of visibility analysis in complex structures, a proposed visibility algorithm is implemented into the developed methods of texture mapping and true orthophoto generation. The algorithm filters occluded areas based on a patch processing using a grid square unit set around the projected vertices. The depth of the mapped triangular vertices within the patch neighborhood is calculated to assign the visible one. In this contribution, experimental results from different historical sites in Jordan are presented as a validation of the proposed algorithms. Algorithms show satisfactory performance in terms of completeness and correctness of occlusion detection and spectral information mapping. The results indicate that hybrid methods could be used efficiently in the representation of heritage structures.

With the increasing requirements of power supply quality and operation economy of the microgrid in smart grid field, real-time energy scheduling methods that highly rely on the cyber system are inevitable supports for the optimal operation of microgrids. As a typical cyber-physical system, the disturbance and failure on the cyber side may make the performance of microgrids deviate from the expected ones. To quantify the degree to which these cyber contingencies influence the microgrid system, we propose a novel quantification and analytical framework. In this framework, the cyber system of a centrally controlled microgrid is abstracted consisting of information conversion, transmission and routing forward, as well as fusion and calculation. On this basis, the general information flow is modeled through information mapping between measured state and control command. Furthermore, an equivalent model for a cyber-physical microgrid system is formulated by integrating information mapping model into the state transition of physical microgrid. With this equivalent model, a unified impact analytical procedure is presented to accurately quantify the physical impact of multi-cyber-contingencies in both economy and reliability aspects. Numerical simulations on a microgrid validate the reasonableness and effectiveness of the proposed method.

In this paper, a novel method that utilizes the information of coding unit (CU) from source video to accelerate the downscale transcoding process for High Efficiency Video Coding (HEVC) is proposed. Specifically, the CU depth and prediction mode information are first extracted into matrices in block level according to the decoded source video. Then we use the matrices to predict CU depth and prediction mode at CU level in the target video. Finally, some effective rules are introduced to determine CU partition and prediction mode based on the prediction. Our approach supports the spatial downscale transcoding with any spatial resolution downscaling ratio. Experiments show that the proposed method can achieve an average time reduction of 59.3% compared to the reference HEVC encoder, with a relatively small Bjontegaard Delta Bit rate (BDBR) increment on average. Moreover, our approach is also competitive compared to the state-of-the-art spatial resolution downscale transcoding methods for HEVC.

The information of the analytical account which characterizing a state and enterprise activity results for the check period on the top level is defined. The relationship between the analytical accounting and the characteristics of the enterprise as an object of management is established. Functional dependencies which characterizing the interaction of the DSS audit variables are formalized. The rules and properties of sets mappings correspondence of numerical values of variables are defined as a preliminary stage of data preparation for audit. Based on the obtained results, the essence of the generalized-multiple information mapping technique in the DSS of the audit is formulated. The application of this technique will allow: to reduce the volume of analyzed multidimensional data or actual verification at lower levels by allocating equivalent subsets at the upper levels; use the results of a polyalternative analysis on a set of characteristics of data sets for preparing decision-making with polyalternative criteria for assessing the equivalence of sets in IT multi-level DSS audit; determine the reason for the lack of data equivalence, through the definition of functional relationships, the implementation of which does not correspond to the properties of mappings.

This paper reports an investigation and assessment of the digital information, provided via multiple channels, for the 2015 World Exposition (Expo) in Milan. Using emerging theoretical constructs in cross-channel information architecture as a lens, the researchers examined aspects of the digital information ecology that supported the Exposition event. This study focused, firstly, on how well information and its structure maintain a coherence that is useful and meaningful to its target audience across various technologies and platforms. Secondly, it attended to the means and mechanisms for moving from one information artefact to another and it comments on the ease with which global audiences traversed the multiple channels that formed the information environment of Expo 2015.

Background Prior studies of clinical trial planning indicate that it is crucial to search and screen recruitment sites before starting to enroll participants. However, currently there is no systematic method developed to support clinical investigators to search candidate recruitment sites according to their interested clinical trial factors. Objective In this study, we aim at developing a new approach to integrating the location data of over one million heterogeneous recruitment sites that are stored in clinical trial documents. The integrated recruitment location data can be searched and visualized using a map-based information retrieval method. The method enables systematic search and analysis of recruitment sites across a large amount of clinical trials. Methods The location data of more than 1.4 million recruitment sites of over 183,000 clinical trials was normalized and integrated using a geocoding method. The integrated data can be used to support geographic information retrieval of recruitment sites. Additionally, the information of over 6000 clinical trial target disease conditions and close to 4000 interventions was also integrated into the system and linked to the recruitment locations. Such data integration enabled the construction of a novel map-based query system. The system will allow clinical investigators to search and visualize candidate recruitment sites for clinical trials based on target conditions and interventions. Results The evaluation results showed that the coverage of the geographic location mapping for the 1.4 million recruitment sites was 99.8%. The evaluation of 200 randomly retrieved recruitment sites showed that the correctness of geographic information mapping was 96.5%. The recruitment intensities of the top 30 countries were also retrieved and analyzed. The data analysis results indicated that the recruitment intensity varied significantly across different countries and geographic areas. Conclusion This study contributed a new data processing framework to extract and integrate the location data of heterogeneous recruitment sites from clinical trial documents. The developed system can support effective retrieval and analysis of potential recruitment sites using target clinical trial factors.
