Urban Improvement: The Making And Using Of Green Spaces In St. Petersburg (1870s-1910s)

With intensive industrialization process St. Petersburg faced with urbanization by the second half of the 19th century. Due to the transformation of the city green spaces became part of this process, so environmental as well as health care issues occurred at the center of public debates. It was then that issues related to urban green spaces occurred in the focus of public attention. They became the main topics in periodicals, as well as in special brochures and publications on urbandevelopment. Gardens and parks were perceived as an important element of the urban environment, as a significant public good, and they were crucial due to the recreational and sanitary point of view, as places necessary for residents to relax and to improve their health while walking there. As a result, green spaces have become part of the process of forming the public sphere in St. Petersburg. Ceasing to be private, they gradually offered more leisure activities for all residents of the city. However, the (re)making of green spaces in St. Petersburg was a result of a clash of interests of different actors involved – gardeners and architects, who were members of professional communities, and representatives of the city municipality. The same interest was paid by citizens whose voices are explicitly seen in periodicals. Each interest group had different vision of how urban gardens and parks should have been organized and functioned. Examining extensive body of sources that included journal and wallpaper publications and official documents of the office of city authorities I would like to analyze how different communities of experts that were involved in these transformations worked with nature in the urban environment and to focus on contested character of the emerging green public spaces.

Suggestion, Calculations, Practical Approbation of the Resonant Amplifier of the Reactive Electrical Power

The aim of the paper consists in suggestion, theoretical and experimental justification of the principal workability of the electrical power amplifier proposed scheme consisting of two sequential resonant circuits with the regulated level of the electromagnetic coupling between them. Scientific novelty is determined by the formulated aim an achievement of which is based on conclusions of the theoretical analysis and experiments fulfilled for the acting model of the proposed electrical power amplifier. The base analytical expressions for the electromagnetic processes analysis in the scheme of the suggested resonant power amplifier are got. The reliability of the found analytical dependencies was shown with help of the limit passages to the according to analogs in the authoritative special publications. As the conducted experiments have shown that resonant conditions in the circuits of the suggested electrical power amplifier are fulfilling with high strictness (the frequency discrepancies are no more than ~ 0.8 %). The discrepancies between the measurement and the calculation results are quite small and can be explained by the external electromagnetic fields influence (the fields superposition of the "output" solenoid and the coupling transformer). In whole, the got results are illustrating the real possibilities of the power multiple amplifying (~35 times) in the suggested scheme of the electromagnetic resonant converter which was based on the advancement of the Tesla transformer creator ideas.

Internationalisation as a Long-Term Strategic Project of the Post-War Renewal of the Yugoslav Archaeology (1950–1971)

Archaeology in the countries which belonged to Yugoslavia (1918–1991) was mosaic of different traditions. The development of archaeology was greatly affected by political changes in the last 150 years; all of them required significant re-contextualisation of the discipline and its practice. The renewal of archaeology after the Second World War, in the context of Socialist Yugoslavia, acted on both levels, in building-up the existing national (republican) archaeological disciplinary frameworks, and in forging ‘new’ common Yugoslav archaeology. Key role in this process played the Archaeological Society of Yugoslavia, established in 1950 as the principal coordinating scholarly organisation in the country. The Society’s immediate task was to create conditions for the cooperation of all archaeologists in the country, including the international promotion of the (new) Yugoslav archaeology. Despite having less than 100 archaeologists in the 1950s, the Society designed very ambitious program of ‘internationalisation’ (e.g. exchange of publications, participation at the international conferences, grants, invitation to foreign scholars, special publications published exclusively in foreign languages etc.) which proved highly successful in a very short time. The peak of these endeavours was participation at the 1st International Congress of Slavic Archaeology in Warsaw (1965) and organisation of the 8th Congress of the UISPP in Belgrade (1971); the event which could not be organised without intensive promotion and networking of the Yugoslav archaeologists in the international academic arena in the 1950s and 1960s.

Este artigo analisa uma reportagem proveniente de uma das publicações especializadas mais conhecidas pelo público dos educadores: a Nova Escola. O objetivo principal é analisar como o agir docente é representado nesse texto, partindo de uma perspectiva de ensino como trabalho complexo, permeado por conflitos, prescrições e coerções (BRONCKART, 2006a; MACHADO, 2004; AMIGUES, 2004; BUENO; 2007; BUTTLER, 2009). Assim, a análise textual-discursiva empregada tem como base os pressupostos do Interacionismo Sociodiscursivo (BRONCKART, 2004, 2006a, 2006b, 2008), os quais atribuem à linguagem um papel central no estudo das representações e avaliações relacionadas ao trabalho docente, dentro e fora da esfera educacional. De modo geral, os resultados indicam que o professor, nessa reportagem, é predominantemente configurado como profissional desvinculado dos conflitos e das prescrições que permeiam o seu métier, cujas iniciativas individuais – centradas na busca por cursos, capacitações e materiais de apoio – seriam suficientes para garantir o êxito de seu trabalho.

Sustainable Supply Chain Management—A Literature Review on Emerging Economies

In recent years, the interest in sustainable supply chain management has increased significantly in both business and academic areas. This is reflected in the growing number of articles, conferences, special publications and websites devoted to the subject. Nonetheless, sustainable development in emerging economies just started gaining importance. The objective of this article is to review, from a global perspective, the existing literature regarding sustainable supply chain management (SSCM) in emerging economies. For this purpose, a systematic literature review was performed, analyzing 56 articles from the year 2010 to April 2020 from a descriptive and content approach. Subsequently, the results are presented, showing the increasing interest in SSCM, however lagging behind in emerging economies’ research versus developed ones. Findings indicate the context in developing countries plays an important role when conducting empirical or case study investigations. Additionally, the integration of the three dimensions of sustainability and how they impact supply chain performance becomes crucial to research from an emerging economy perspective. Consequently, limitations of this work are presented, and opportunities are identified for future lines of research, in particular in key supply chain functions. Finally, the conclusion confirms the need for further research from different supply chain viewpoints, such as collaboration, sustainable practices innovation, sourcing and supplier development from emerging countries’ standpoint and background.

Exploring the Barriers to Oral Health Care Perceived by Parents/ Caregivers of Children with Disabilities in Qatar

Background: The impact of dental diseases is more profound and prolonged among children with disabilities as they are reliant on their parents/caregivers for their oral health care as well as dental treatment needs as the parents/ caregivers of these challenged children assume the primary decision-making role. The potential barriers perceived by the parents/caregivers have a significant bearing on the oral health of disabled children. We aim to elicit these barriers so as to provide valuable insights towards the planning and implementation of the oral health programs. Objectives: 1. To explores the barriers to oral health care perceived by parents/caregivers of children with disabilities in Qatar. 2. To compare the perceived barriers between parents/caregivers of physically and intellectually disabled children. Methodology: A cross-sectional, descriptive, questionnaire study was carried out among parents/caregivers of children with disabilities who attended eight Special Needs Public Schools in Qatar. A Chi-square test was employed to evaluate the association of perceived barriers with the type of disability. Results: 84 parents/caregivers (89%) were not aware of the oral treatment facilities available for their challenged children. 79% reported a lack of awareness and knowledge regarding the prevention and treatment of dental diseases. 41% also perceived that the dentist would be reluctant to treat their disabled children. Conclusion: The results of this study depict the potential barriers perceived by the parents/caregivers towards oral health care of their disabled children.

Ethnography and Public Scholarship: Ethical Obligations, Tensions, and Opportunities

The article introduces the special issue, “Ethnography and Public Scholarship: Ethical Obligations, Tensions, and Opportunities.” The editors begin with a discussion of Alice Goffman’s On the Run. The popularity and influence of Goffman’s ethnography, coupled with critique and controversy, represent the promise and peril of ethnography as public scholarship. The case operates as a portal to explore at once familiar and still often unanswered methodological and ethical questions as ethnographers engage in public scholarship. After reviewing key considerations, the editors provide snapshots of the papers, papers that explore topics such as ethnography as policy-relevant research, representations of marginalized populations, compliance with regulatory agencies, protection of participants’ rights, and documentation and sharing of data. Recognizing the importance of Mills’ appeal to encourage the sociological imagination, the editors argue that, taken as a whole, the papers demonstrate complex methodological and ethical considerations as well as immense possibilities to inform and reframe social issues.

Designing and Building Secure Electronic Medical Record Application by Applying AES-256 and RSA Digital Signature

Medical records consist of health data that must be kept confidential and is regulated in Indonesian law. Until now the implementation of electronic medical records in Indonesia has not been clearly regulated in a law, while Regulation of the Minister of Health of the Republic of Indonesia state that medical records must be made in writing, complete, and clearly or electronically. In view of this, another approach than the regulation is needed to be able to meet the confidentiality of the data in the regulation, in electronic form. In this study, an electronic medical record application was designed and built that can meet the requirements of the legislation. The application encrypts patient’s health data stored on medical records using the AES-256 algorithm for data confidentiality. The use of AES-256 has been standardized based on the Federal Information Processing Standards Publication 197 and RSA Digital Signature digital signature because it has been standardized based on Federal Information Processing Standards Publication 186-4 and NIST Special Publication 800-89. The proposed application have been made have passed security testing using 6 testcase based on the reference paper.

Feminismos y género en los Estudios Internacionales

En las últimas décadas, el rol específico de las mujeres en las relaciones internacionales ha recibido más atención y las teorías feministas han ganado terreno en el debate intelectual, lo que ha contribuido a una sensibilización general hacia la incorporación del análisis de la categoría de género en la disciplina de las Relaciones Internacionales. De hecho, uno de los rasgos característicos de la disciplina había sido la invisibilización de las estructuras de género que impactan a hombres y mujeres de forma distinta. Sin embargo, con la irrupción del llamado “cuarto debate” se abrió una nueva oportunidad para pensar lo internacional desde miradas más críticas e inclusivas. El impacto de los estudios feministas tuvo lugar a finales de la década de 1980 con una publicación especial sobre género en la revista académica Millennium: Journal of International Studies. De gran relevancia en la actualidad son las teorías producidas fuera de los centros hegemónicos y que cuestionan tanto las teorías clásicas como el sistema de género occidental por encubrir un proyecto etnocéntrico. En efecto, las teóricas post y decoloniales pretenden desestabilizar los discursos hegemónicos sobre una supuesta experiencia universal de las mujeres. En este sentido, el objetivo central del presente artículo es realizar una revisión bibliográfica sobre las principales escuelas feministas, así como sistematizar la pluralidad de teorías y de prácticas feministas que han tenido lugar en el devenir de los estudios internacionales. De esta forma, tras una breve introducción sobre el surgimiento de los enfoques feministas en la disciplina, el presente estudio realiza un análisis de las aportaciones de las principales escuelas feministas: el feminismo liberal, el feminismo del punto de vista, el feminismo constructivista, el feminismo posmodernista, el feminismo postcolonial, el feminismo decolonial, la teoría queer y el enfoque sobre las masculinidades. A través del examen de estas diferentes corrientes teóricas, se analizará su impacto en la disciplina de las Relaciones Internacionales, evidenciando los cambios epistemológicos, metodológicos y ontológicos presentes en las diferentes escuelas. Las teorías feministas en las Relaciones Internacionales deben ser abordadas, pues, de manera multidimensional, en el sentido de reconocer las diferencias y elementos comunes respecto a las experiencias de las mujeres, hombres y disidentes sexuales desde diferentes latitudes.

An efficient novel color image encryption algorithm based on 3D Lü chaotic dynamical system and SHA-512

In this paper, an efficient novel dual permutation–substitution structure-based color image encryption algorithm is proposed. Initially, the Secure Hash Algorithm-512 (SHA-512) is applied to the input image to generate the initial values for the Lü system dynamically. In the first stage of permutation, inter-color-component pixel shuffling is carried out with a circular pixel-swapping mechanism. In the second stage, intra-color-component pixel shuffling is executed, based on pseudorandom positions generated by the Lü chaotic system. Pixel values are changed in the substitution stage, based on float-valued chaotic sequences generated by the Lü system. The performance of the proposed algorithm is evaluated with metrics such as key space, key sensitivity, histograms, correlation coefficients (vertical, horizontal and diagonal), information entropy, number of pixel changes rate (NPCR), unified average changing intensity (UACI), peak signal-to-noise ratio (PSNR), mean absolute error (MAE), contrast analysis, encryption time and the National Institute of Standards and Technology Special Publication 800-22 (NIST SP 800-22) statistical test. The experimental results obtained and performance assessment show that the proposed scheme has produced good results.

Legal Information in Special Education: Accuracy with Transparency

ABSTRACT This article presents a tool for systematic consideration of the accuracy of the legal contents of publications in special education. The tool is a two-dimensional grid with one axis having three overall levels relative to legal requirements and the other axis having the three perspectives symbolized by the courtroom roles of pro-parent, impartial, and pro-district representatives. The purpose is to facilitate authors‘ self-reflecting awareness and readers’ assessment of the legal accuracy of special education publications, including careful consideration of the interrelated issue of transparency. Finally, this tool is intended as the starting, rather than ending, point of such systematic reflection, including the addition of other significant dimensions, such as legal expertise, for ultimate improvement of the legal literacy of professionals and parents in special education.

Lightweight Dynamic Group Rekeying for Low-Power Wireless Networks in IIoT

In this article, a novel pseudorandom key chaining (PRKC) algorithm is introduced and evaluated. This lightweight symmetric scheme enables a transmission-triggered time variation of group keys in low-power wireless networks during broadcasting or multicasting. The proposed algorithm uses pseudorandom (PR) sequences, generated at the physical (PHY) layer of radio transceivers during a communication session, to symmetrically refresh the encryption keys on both sides of a communication link. This solution is scalable and suitable for large networks of nodes with limited resources in an Industrial Internet-of-Things (IIoT) environment. The strength of generated keys was tested with the use of the National Institute of Standards and Technology Special Publication 800-22 (NIST SP 800-22) statistical suit. No binary patterns that may indicate a vulnerability were detected. The randomness of generated key sequences was further analyzed with the use of strange attractors approach which demonstrated that these sequences are robust against attacks, such as spoofing or intelligent brute forcing. To assess the real-time delay and computational overhead of the algorithm, it was implemented on a Raspberry Pi board. The results demonstrated that the PRKC algorithm runs over 60% faster and requires over 40% less CPU effort per round than the conventional hashing-based schemes. In addition, it does not require any communication overhead and transmission energy.

This study is to evaluate the training time and training-frequency between korea, Japan, USA and Swiss in student swimmers. All trainers and student swimmers participated Self-Management Questionnaires about training contents (season vs. off season, training time, training frequency) and data was collected. Another case in foreign countries (Japan, USA and Swiss) were collected from web-site of national swimming association, special students swimming boos and publication. The training frequency and training time in korean swimmers are 5~7times/week, 25 ± 2.7hour/week for elementary students, 5~7times/week, 30 ± 6.5hour/week for middle school students and 6~7times/week, 41.7 ± 17hour/week for high school students. The training frequency and training time in Japan swimmers are 2~3times/week, 2~3hour/week for elementary students, 3times/week, 9hour/week for middle school students and 6times/week, 15hour/week for high school students. The training frequency and training time in USA swimmers are 3times/week, 1.8hour/week for elementary students and 3times/week, 2.3hour/week for middle school students and 5times/week, 5~7hour/week for high school students. The training frequency and training time in Swiss swimmers are 3~4times/week, 3~4hour/week for elementary students, 3-8times/week, 4.5~12hour/week for meddle school students and 3~8times/week, 4.5~12hour/week for high school students. Korean student swimmers have at least 5 times higher training-time and at least 2 times more higher training-frequency in all subject groups. Especially, the question about reducing the training times, 40.1% korean students and 39.2% trainer gave a negative answer. Student swimmers are not miniatures of adult athletes. Because their minds are not only quantitative, but also qualitatively different as compare to adult. They must be trained with great care and the trainers must provide more professional and individual training program to student swimmers. In particular, individual training programs should be selected for the progress of training effects.

ARTISTIC AND AESTHETIC COMPETENCIES DEVELOPMENT: TRAINING TEACHERS USING DECORATIVE AND APPLIED ARTS

As Ukrainian national system of education is coming into being, aiming to promote development of personal competences on the basis of culture, art, and folk traditions of the Ukrainian people, introducing the spiritual heritage to the young generation, the problem of developing artistic and aesthetic competencies of the future teachers by means of decorative and applied arts becomes topical. The didactic value of the arts, as well as their limitless potential for competencies development are well recognized. This urged us to develop an artistic and aesthetic competencies training technique for the future teachers with the use of decorative and applied arts. The aim of the study is to test experimentally the effectiveness of this technique. The theoretical methods used are: analysis of psychological, pedagogical, methodological and specialized publications, of educational documentation; analysis, synthesis, abstraction, and systematization of data, comparative analysis of dissertations. Empirical methods are: questionnaire survey, observation, testing, independent peer review, analysis of students’ practical results to determine criteria, indicators and levels of artistic and aesthetic competencies development; pedagogical experiment. Also used is the mathematical statistics method to analyze and determine effectiveness of the technique.

Itinerary books (itineraria) of the Vysotskys’ printing house

The study gives a new outlook on the activities of the first Tyumen printing house, which was founded by K. N. Vysotsky in 1869 and existed until 1909. The scientific novelty of the research is due to the following: 1) book publishing is considered as part of the media revolution carried out by K. N. Vysotsky thanks to the opening of the first photography studio (1866), lithography studio (1867), printing house (1869), and a newspaper publishing news and advertisements (1879) in a provincial Siberian town; 2) publishing activities of K. N. Vysotsky and L. K. Vysotskaya are linked with the history of Siberian steam navigation in the 1870–1890s. The purpose of the article is to characterize Russian dorozhniki - itinerary books as a special type of publications in the Vysotskys’ printing house, to identify their diversity and role in the activities of steamship companies, in particular the Kurbatov and Ignatov Partnership. A bibliological analysis based on the structural-typological method within the context and system approaches allows a new interpretation of the role and place of the Vysotskys’ printing house in the history of Siberian book culture. The author comes to the conclusions that about 20% of the repertoire (11 of 56 books) of the Vysotskys’ printing house are books about steamboats and rivers. They represent a semantic unity, a unique series structured by space (more than 3000 km along West Siberian rivers from Tyumen to Tomsk) and the idea of industrialization and cultural development of new lands. The structural dominance of the series belongs to a special publication type: dorozhnik (an itinerary book), the purpose of which was to indicate the distance between settlements and to serve as a travel guide on Siberian rivers. Publication of such books, which are known to exist since the ancient Rome, testifies to the high print culture of the Vysotskys publishers. These books are very diverse: brief guidebooks coexisted with lithographic cartographic editions and advertising catalogs in the genre of history writing and ethnographic travel essays. The significance of the itinerary books published by the Vysotskys lies in the cultural brand they formed for Tyumen as a town and the birthplace of all navigation along West Siberian rivers.

Leveraging Big Data and Analytics to Improve Food, Energy, and Water System Sustainability.

With the world population projected to grow significantly over the next few decades, and in the presence of additional stress caused by climate change and urbanization, securing the essential resources of food, energy, and water is one of the most pressing challenges that the world faces today. There is an increasing priority placed by the United Nations (UN) and US federal agencies on efforts to ensure the security of these critical resources, understand their interactions, and address common underlying challenges. At the heart of the technological challenge is data science applied to environmental data. The aim of this special publication is the focus on big data science for food, energy, and water systems (FEWSs). We describe a research methodology to frame in the FEWS context, including decision tools to aid policy makers and non-governmental organizations (NGOs) to tackle specific UN Sustainable Development Goals (SDGs). Through this exercise, we aim to improve the “supply chain” of FEWS research, from gathering and analyzing data to decision tools supporting policy makers in addressing FEWS issues in specific contexts. We discuss prior research in each of the segments to highlight shortcomings as well as future research directions.

The state of integration of ukrainian orthopedic studies in the world science

The involvement of Ukrainian clinical scientists in the field of orthopedics and traumatology in world of medicine is an urgent problem, as evidenced by the level of reflection of domestic research in international specialized publications. Objective: to determine the features of scientific activity of Ukrainian orthopedic and traumatology surgeons based on the analysis of quantitative indicators as Scimago Journal & Country Rank, Scopus and Web of Science.Methods: the Hirsch index (h-index, Scopus) of 92 doctors of medical sciences in the specialty «Traumatology and Orthopedics», selected from the «Scientists of Ukraine» database (V. I. Vernadsky National Library), was evaluated. The number of publications of these researchers in foreign journals in general (according to the Scimago Journal & Country Rank) was analyzed. We also estimated the dependence on the quartile of the journal (Web of Science) in the specialty Orthopedics and Sports Medicine from 2014 to 2018.Results: for the studied period of time (2017–2018), the publication activity of Ukrainian doctors was increased in the specialty Orthopedics and Sports Medicine. So, in 2017, Ukraine took the 69th place (Scimago Journal & Country Rank) in terms of the number of publications in the ranking of countries of the world, and in 2018 — already 62nd. More than half of the identified works were published in the journals of the fourth quartile, and only a quarter of the first. The citation index of the most orthopedic traumatology surgeons remains low, which can be explained by the choice of a journal for publication with a low impact factor or a small number of published works indexed by Scopus and Web of Science.Conclusions: it is necessary to introduce Evidence-based medicine research standards into everyday practice. This determines the importance of teaching our native scientists how to plan and conduct research study, analyze and prepare for printing the results.
