Use of Jacobians for inverse kinematics of articulated robots : a study on approximate solutions
Authors:   , Demby's Uriel Jacket Tresor
Published: August 2021

In the context of articulated robotic manipulators, the Forward Kinematics (FK) is a highly non-linear function that maps joint configurations of the robot to poses of its endeffector. Furthermore, while in the most useful cases these functions are neither injective (one-to-one) nor surjective (onto), depending on the robot configuration -- i.e. the sequence of prismatic versus revolute joints, and the number of Degrees of Freedom (DoF) -- the associated Inverse Kinematics (IK) problem may be practically or even theoretically impossible to be solved analytically. Therefore, in the past decades, several approximate methods have been developed for many instances of IK problems. The approximate methods can be divided into two distinct categories: data-driven and numerical approaches. In the first case, data-driven approaches have been successfully used for small workspace domains (e.g., task-driven applications), but not fully explored for large ones, i.e. in task-independent applications where a more general IK is required. Similarly, and despite many successful implementations over the years, numerical solutions may fail if an improper matrix inverse is employed (e.g., Moore-Penrose generalized inverse). In this research, we propose a systematic, robust and accurate numerical solution for the IK problem using the Unit-Consistent (UC) and the Mixed (MX) Inverse methods to invert the Jacobians derived from the Denavit-Hartenberg (D-H) representation of the FK for any robot. As we demonstrate, this approach is robust to whether the system is underdetermined (less than 6 DoF) or overdetermined (more than 6 DoF). We compare the proposed numerical solution to data driven solutions using different robots -- with DoF varying from 3 to 7. We conclude that numerical solutions are easier to implement, faster, and more accurate than most data-driven approaches in the literature, specially for large workspaces as in task-independent applications. We particularly compared the proposed numerical approach against two data-driven approaches: Multi-Layer Perceptron (MLP) and Adaptive Neuro-Fuzzy Inference System (ANFIS), while exploring various architectures of these Neural Networks (NN): i.e. number of inputs, number of outputs, depth, and number of nodes in the hidden layers.
Enhancing network-edge connectivity and computation security in drone video analytics
Authors:   , Esquivel-Morel Alicia
Published: August 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Unmanned Aerial Vehicle (UAV) systems with high-resolution video cameras are used for many operations such as aerial imaging, search and rescue, and precision agriculture. Multi-drone systems operating in Flying Ad Hoc Networks (FANETS) are inherently insecure and require efficient and end-to-end security schemes to defend against cyber-attacks (i.e., Man-in-the-middle (MITM), Replay and Denial of Service (DoS) attacks). In this work, we propose a cloud-based, intelligent security framework viz., "DroneNet-Sec" that provides network-edge connectivity and computation security for drone video analytics to defend against common attack vectors in UAV systems. The proposed framework includes three main research thrusts: (i) a secure hybrid testbed management that synergies simulation and emulation via an open-source network simulator (NS3) and a research platform for mobile wireless networks (POWDER), (ii) an intelligent and dynamic decision algorithm based on machine learning to detect anomaly events without decreasing the performance in a real-time FANET deployment, and (iii) a web-based experiment control module that features a graphical user interface to assist experimenters in the execution/visualization of repeatable and high-scale UAV security experiments. Our performance evaluation experiments in a holistic hybrid-testbed show that our proposed security framework successfully detects anomaly events and effectively protects containerized tasks execution in drones video analytics in a light-weight manner.
Bases Biomoleculares da Oncogênese Cervical

Published: August 2021

A incidência e a mortalidade de câncer cervical têm diminuído, em parte pelo diagnóstico precoce e tratamento de lesões precursoras do câncer cervical. Neste trabalho são apresentadas as bases para a compreensão da oncogênese cervical. Diversos estudos demonstraram que o maior risco para desenvolver câncer de colo uterino é a não realização de exames citopatológicos, rotineiramente. O ciclo celular é controlado por genes supressores e estimuladores da proliferação celular. Quando ocorrem mutações, proto-oncogenes tornam-se oncogenes, que são carcinogênicos e causam multiplicação celular excessiva. Os genes supressores, em contraste, contribuem para o desenvolvimento de câncer quando são inativados por mutações. A perda da ação de genes supressores funcionais pode levar a célula ao crescimento inadequado. O ciclo celular também pode ser alterado pela ação de vírus, entre eles o HPV (human papiloma virus), de especial interesse na oncogênese cervical. Os tipos HPV 16 e 18 são os de maior interesse, freqüentemente associados a câncer cervical e anal. O mecanismo pelo qual os tipos de HPV transformam as células ainda não é completamente compreendido. O conhecimento das bases moleculares que estão envolvidas na oncogênese cervical tem sido possível devido a utilização de técnicas avançadas de biologia molecular. Algumas destas técnicas permitem identificar grupos de HPV de alto ou baixo risco (captura híbrida) ou identificação de tipos virais específicos (PCR). São técnicas de fácil utilização em laboratórios equipados, embora ainda com custo elevado.

Published: August 2021

Os autores documentam cinco casos de pacientes femininas portadoras de câncer de mama com disseminação ocular. Na série, quatro pacientes já apresentavam doença sistêmica no momento da comprovação de metástase ocular, enquanto uma apresentou lesão orbitária como manifestação inicial de tumor mamário não identificado previamente. A idade na época do diagnóstico de carcinoma de mama variou de 36 a 48 anos. O intervalo entre o diagnóstico de câncer de mama e o surgimento dos sinais e sintomas oculares variou de zero a 128 meses, com média de 60 meses. O intervalo entre o diagnóstico e a recidiva da doença variou de 13 a 132 meses e entre esta e o óbito variou de 4 a 50 meses. Neste estudo duas pacientes receberam quimioterapia; e as demais, a associação de quimioterapia e radioterapia. É importante assinalar que duas mulheres desenvolveram metástases oculares em vigência de quimioterapia. Embora a sensibilidade da metástase à radioterapia esteja bem documentada em vários estudos, há poucas publicações que comprovam a eficácia da quimioterapia.

MANAGEMENT OF INNOVATION PROCESSES AT THE ENTERPRISE
Authors: Gorobynskaya Marianna
Published: August 2021

The concept of the development of innovative activities of modern production is relevant, since innovations determine the competitiveness of companies, industries and entire countries in world markets and become new sources of economic growth based on knowledge. The low activity of the use of innovations at domestic enterprises testifies to the insufficient effectiveness of measures aimed at preserving and developing their scientific and technological potential. The technological backwardness of Ukraine from highly developed countries largely depends on the prevalence of mainly closed models of innovation, which do not contribute to the formation and development of a modern innovative environment. The effectiveness of high-tech production is determined, first of all, by the rationale for making decisions on the use of various models of innovative projects while maintaining intellectual property rights and reducing the likelihood of possible risks. The characteristics of the evolution of existing models of innovation management allowed us to analyze the features of their manifestation and substantiate the need to introduce models of the new sixth generation into the domestic economy using world experience. The transition of enterprises and firms to open forms of innovative development involves the involvement of partners, research centers and other structures in order to implement new scientific ideas. And cooperation between domestic and foreign innovative enterprises makes it possible to actively exchange knowledge, experience and competencies. When introducing open innovation models, the following prerequisites must be met: adherence to the principle of openness and expanding cooperation with external partners, scientific institutions, suppliers and consumers; analysis, as well as the choice of an array of various innovations that exist outside the enterprise and are of great value to it; combining «external» and «internal» knowledge into a more complex combination of new concepts and competencies, allowing you to create the latest business systems and models. The considered advantages of open innovation models and numerous examples of their active dissemination in world practice make it possible to name and formulate the main ways and possibilities of creating a modern domestic innovation system.
INVESTMENT AND INTELLECTUAL PROPERTY IN ENTREPRENEURSHIP
Authors: Konstantynova Tetyana , Savchenko Tetyana
Published: August 2021

The knowledge-intensive enterprises have a fundamental role in the world economy. To stay competitive, businesses need to constantly create new knowledge. The businesses have certain advantages over large corporate structures: they are able to respond quickly to the changing market demand, they are flexible in organizational terms and often have the effective internal communications. As a result, small businesses can more easily incorporate the new working methods and processes into their operations and therefore be innovative. The purpose of intellectual property law is to stimulate the innovation. In summary, the accumulation of physical capital alone will not be sufficient to support development in a new economy and new global competition. Enterprises must achieve a higher trajectory of technological capabilities and competitiveness. Such a qualitative transformation should be based on the formation of knowledge that is driven by innovation, driven by shared connections and supported by lifelong learning. The main purpose of the study is to analyze the state of investment in innovation in enterprises in Ukraine and the protection of intellectual property rights. Intellectual property (IP) systems can be crucial in helping new businesses transform their innovation potential and creativity into market value and competitiveness. Intellectual property rights (IPR) allow innovative entrepreneurs to protect their inventions. They can also perform many other functions, such as signalling current and future value to investors, competitors and partners, accessing knowledge markets and networks, and preventing competitors from patenting related inventions. However, IP systems can also hinder the development of entrepreneurial ideas and hinder the dissemination of knowledge and innovation. Firm-level evidence suggests a positive correlation between patenting and new business growth, access to venture capital, and survival. The data show a huge increase in patent applications over the last decade, which differs significantly in the share of young patent firms in different countries.
SCHEME FOR ASSESSING THE NEED FOR MARKETING TESTING MARKET PROSPECTS COMMODITY INNOVATIONS IN THE PRACTICAL ACTIVITIES OF ENTERPRISES IN THE OLD INDUSTRIAL REGIONS OF UKRAINE
Authors: Nagornyi Yeugene , Cherednyk Inna , Berezova Svitlana
Published: August 2021

The innovative activity of industrial enterprises to create commodity innovations must end with their successful commercialization. Success in this case involves compensation for all costs incurred for their creation and introduction to the market, and also improving the image and reputation of the company in the eyes of consumers and other economic counterparties. But, quite often, in practice, the situation is different: commodity innovations in the market fail, the company incurs losses, and his image and reputation suffer. This is due to the manifestation of various reasons, and one of the main in this list – absence of marketing tests of market prospects of product innovations. Unfortunately, the domestic industrial sector seldom assesses market prospects of the developed commodity innovations by means of marketing testing; because of we have negative consequences at the stage of commercialization. That’s why this research is devoted to the need to introduce marketing testing of market prospects of product innovations.
The article presents indicators that determine the need for marketing testing of market prospects for product innovations in the practice of innovative industrial enterprises. These indicators include: efficiency of innovative activity of the enterprise; projected success of product innovations in the market; analysis of the implementation of the plan for the sale of product innovations over the past few periods; the level of consideration of the needs and demands of consumers when designing product innovations; the level of novelty and competitiveness of product innovations; the magnitude of innovation risk; the presence of technical miscalculations in the design of product innovations; level of consumer loyalty, etc. These indicators are formed on the basis of generalization of a number of scientific sources on this issue, and on the results of research on the successful implementation of domestic innovation projects for the development of product innovations. The study developed a scheme for assessing the need to decide on the transition to a marketing model for the development of product innovations, which includes the procedure of marketing testing of their market prospects at the stages of the innovation cycle. In general, the introduction of marketing testing at the stages of the innovation cycle provides a fundamental opportunity for an industrial enterprise to make an informed decision about the readiness of its product innovations for commercialization by using their market prospects. The analysis is a future development for the implementation of organizational and economic testing mechanism in the practical activities of domestic innovative enterprises.
TНЕ INFLUENCE OF DEMOGRAPHIC PROCESSES ON ECONOMIC SECURITY OF SUMY REGION
Authors: Vesperis Svitlana , Samus Hanna , Scherbina Olha
Published: August 2021

The article analyzes the impact of demographic processes on the economic security of Sumy region. The main characteristics of economic security of the region are highlighted. It is noted that the population of the country is a kind of foundation through which all types of national security, including economic, have their practical application. The following demographic characteristics of the population are analyzed, such as birth rate, death rate, sex and age structure, quantity, migration, which determine the available labor potential of the region and significantly affect the formation of economic security in the region.
The negative tendency of reduction of the available population of the region is established. The sex composition of the population is insignificantly, but women predominate. The natural increase in the population of the region is a negative indicator, which indicates a decrease in the population of the region. Negative dynamics is characteristic of the marriage rate. Divorce is growing in the region. All this indicates the decline of the institution of the family, which in turn will affect the birth rate. With regard to migration growth (reduction) in general, it should be noted that this indicator is also negative, so the number of arrivals is less than the number of departures. But the exception is interstate migration, which is characterized by positive dynamics for the region. The region is dominated by the working age population, which is positive for economic security. At the same time, the share of people of retirement age is greater than children.
In order to solve demographic problems and improve the economic security of the region, measures should be implemented at the regional level (except national ones) to increase the birth rate, support the development of medical institutions to reduce mortality, which will increase natural population growth. Considerable attention should be paid to the development of the production sphere and the sphere of services in order to reduce migration flows from the region and provide available labor resources with jobs, taking into account the gender and age structure. It is necessary to improve the socio-economic living conditions of the population, which will stimulate the migration flow of the population. These events will contribute to the stable and gradual development of the demographic component of economic security of Sumy region.

The strongest link: libraries and linked data
Authors: Byrne Gillian , Goddard Lisa
Published: August 2021

Since 1999 the W3C has been working on a set of Semantic Web standards that have the potential to revolutionize web search. Also known as Linked Data, the Machine‐Readable Web, the Web of Data, or Web3.0, the Semantic Web relies on highly structured metadata that allow computers to understand the relationships between objects. Semantic web standards are complex, and difficult to conceptualize, but they offer solutions to many of the issues that plague libraries, including precise web search, authority control, classification, data portability, and disambiguation. This article will outline some of the benefits that linked data could have for libraries, will discuss some of the non‐technical obstacles that we face in moving forward, and will finally offer suggestions for practical ways in which libraries can participate in the development of the semantic web.

Associations de migrants et coopération internationale. Agriculture et développement durable au Sénégal
Authors: Maggi Jenny , Sarr Dame
Published: August 2021

Depuis la crise alimentaire mondiale, les associations de migrants sénégalais s’engagent en faveur du développement agricole des localités d’origine, en impulsant grâce à leurs projets une dynamique transnationale caractérisée par la circulation de biens, d’innovations et de compétences entre espaces d’accueil et d’origine. Dans cet ouvrage, l’attention est focalisée sur l’analyse d’une série de projets associatifs initiés par des migrants sénégalais établis dans trois pays européens, la France, la Suisse et l’Italie. Ces pays se différencient en termes de politiques visant à soutenir et à reconnaître les associations de migrants dans leur rôle d’acteurs de la coopération. La comparaison se révèle significative pour comprendre si les facteurs propres à chaque contexte d’accueil ont un impact sur les dynamiques associatives et sur les caractéristiques des projets en termes de développement agricole durable. Une telle analyse s’avère instructive aussi pour d’autres pays d’accueil et d’origine des migrants. Elle permet d’avancer des considérations qui visent à enrichir le débat actuel sur les liens entre migration et développement, qui a lieu du global au local auprès de chercheurs, d’organismes internationaux, d’acteurs étatiques et d’organisations de la société civile-ONG, ainsi que d’associations de migrants/diasporas. Jenny Maggi est chargée de cours et collaboratrice scientifique à l’Institut de recherches sociologiques (IRS), Département de Sociologie de l’Université de Genève. Ses recherches récentes portent sur les migrations transnationales, les liens entre migration et développement, la citoyenneté ainsi que sur l’analyse des politiques publiques. Dame Sarr, collaborateur de projet, a été associé à une série d’études sur les migrations transnationales sénégalaises à l’Institut de recherches sociologiques (IRS), Département de Sociologie de l’Université de Genève, et à l’Organisation internationale pour les migrations (OIM).
The Literature-Enactment-Process
Authors: Poeckl Christina V.
Published: August 2021

This project promotes reading literature for students through a new approach termed the Literature-Enactment-Process (LEP) where students can gain access to and comprehend narratives and associated topics of inquiry through a range of phases, with drama-based conventions as a pivotal point. As a pedagogical tool, these performative strategies are embedded in a larger approach that combines individual and collaborative comprehension processes. The LEP seeks to explore literature interactively, in that the student’s individual views, the perceptions of others, and the text details are equally taken into account. Teaching literature should not remain restricted to correctly answering interpretative questions. If teachers demand only one “right” interpretation, learners are deprived of the enrichment and multiple meanings texts can generate. Students must be motivated to think and learn for themselves and for a world which is constantly changing, often to the detriment of our natural environment. For this purpose, the Literature and Ecology (LITECO) workshop was designed to fuse the study of literature and ecological learning using and exemplifying the LEP. At the University of Graz, the Literature-Enactment-Process was tested with current and future teachers as well as language arts students and positively evaluated as an interdisciplinary teaching approach for the (foreign) language classroom in secondary education.
Meine neue Lehrerstimme
Authors: Merkle Lena Katrin
Published: August 2021

Die Stimme einer Lehrperson ist ein zentrales pädagogisches Instrument. Fremdsprachenlehrende sind – zumindest im klassischen Unterricht – zudem Sprachvorbilder im kommunikativen und auch ästhetischen Sinne. Jede Stimme hat einen individuellen Klang, der plastizierbar ist und zielgerichtet eingesetzt werden kann, um ein konstruktives Lernklima zu schaffen. In diesem Beitrag wird ein Seminarmodul für auszubildende DaF-Lehrende vorgestellt, das auf performativ-ästhetischen Arbeitsansätzen basiert. Die Arbeitsform des chorischen Sprechens fand bisher vor allem in der muttersprachlichen und fremdsprachlichen Schulbildung zur Stärkung sprachlich-ästhetischer und persönlichkeitsbildender Kompetenzen Anwendung. Mit ähnlicher Zielsetzung soll im vorliegenden Beitrag aufgezeigt werden, dass der persönliche stimmliche Ausdruck, unter Einbezug des Körperlichen, ein ernstzunehmendes Arbeitsfeld in der fremdsprachlichen Lehrer:innenbildung ist.

Published: August 2021

Technical literacy is a component of professional competence of the pre-service technology teacher. However, the course content of technical disciplines in the pedagogical universities of Ukraine is not consistent with the content knowledge subsequently used in teaching practice of a technology teacher. Also, there is a need in general technical literacy of the students, yet it is developed only in its engineering design aspect. In the paper, it was proved that for the general technical literacy of pre-service technology teachers the basic concepts are the following technical phenomena: motion transmission, changes in kinematic parameters of motion, changes in force parameters of motion. Natural and scientific foundations of the machine drives were used as the basic topic-specific knowledge. It was hypothesized that effectiveness of teaching technical literacy to children would raise if the narrative about the technical phenomena is included in the content of the “Utility machinery” course for the pre-service technology teachers. The pedagogical experiment was performed in the Vinnytsia Mykhailo Kotsiubynskyi State Pedagogical University (Ukraine). It included ascertaining, formative, and control stages. At the ascertaining stage of the pedagogical experiment, the students’ readiness level to study technical phenomena was determined. At the formative stage, the students’ readiness to develop children’s technical literacy was measured. At the control stage, students’ readiness level to develop technical literacy was estimated in experimental and control groups. Theoretical value of the results is in substantiating technical topic-specific content knowledge as necessary for the pre-service technology teachers. Practical significance of the results is in implementation of the narratives about technical phenomena in the learning practice of the students of pedagogical university.

Authors: Kırkıç Kamil Arif , Uludağ Feriha
Published: August 2021

Achievement in a course mostly depends on the students' characteristics and how teachers make their courses effective for their students' learning. Although different characteristics of teachers and students can affect learning outcomes, new approaches like STEM may cause new characteristics which affect students’ achievement as STEM attitudes. This study examines the correlation between secondary school students' STEM attitudes and their achievement in the Technology and Design Course (T & DC). A correlational survey model was applied in the study. A total of 400 students studying in the seventh and eighth grades constitute the sample of the study. A personal data form and STEM attitude test were utilized to collect data. Pearson Correlation Analysis and Regression Analysis techniques were used in the data analysis process. As a result of the analysis, it was found a positive and significant correlation between students' Technology and Design Course achievement and STEM attitudes. Students' attitudes to STEM predict their achievement in the Technology and Design Course by 5.1%. Students developing positive STEM attitudes can further enhance achievement in the (T&DC), which enables students to acquire the necessary design skills to produce technology in the future.

Authors: Gurkan Gokhan , Erdogan Mumin Alper , Yigitturk Gurkan , Erbas Oytun
Published: August 2021

Objective : Peripheral nerve injuries occur mostly as a result of mechanical trauma. Due to the microvascular deterioration in peripheral nerve damage, it becomes challenging to remove free oxygen radicals. Gallic acid is a powerful antioxidant with anti-inflammatory effects and a free radical scavenger. The purpose of the study is to show that gallic acid contributes to the restorative effect in mechanical nerve damage, considering its antioxidant and anti-inflammatory effects.Methods : Thirty male Sprague Dawley albino mature rats were included in the study. Ten of them constituted the control group, 10 out of 20 rats for which sciatic nerve damage was caused, constituted the saline group, and 10 formed the gallic acid group. Post-treatment motor functions, histological, immunohistochemical, and biochemical parameters of the rats were evaluated.Results : Compared to the surgery+saline group, lower compound muscle action potential (CMAP) latency, higher CMAP amplitude, and higher inclined plane test values were found in the surgery+gallic acid group. Similarly, a higher nerve growth factor (NGF) percentage, a higher number of axons, and a lower percentage of fibrosis scores were observed in the surgery+gallic acid group. Finally, lower tissue malondialdehyde (MDA) and higher heat shock protein-70 (HSP-70) values were determined in the surgery+gallic acid group.Conclusion : Gallic acid positively affects peripheral nerve injury healing due to its anti-inflammatory and antioxidant effects. It has been thought that gallic acid can be used as a supportive treatment in peripheral nerve damage.

Kata penatalayanan (stewardship) adalah terjemahan dari kata Yunani Oikonomia. Kata ini dalam bahasa Yunani adalah kata majemuk, yang terdiri dari dua kata: oikos artinya rumah dan nomos artinya hukum. Karena itu menurut Kantonen (1956:2) kata oikonomia secara literal berarti hukum berhubungan dengan rumah, “the management of house or of household affairs” yang berarti suatu sistem pengaturan pelayanan atas suatu rumah atau dalam bidang kehidupan tertentu.Orang percaya (baca: gereja) sebagai pelayan memiliki panggilan dan tanggung jawab untuk mengurus (manage) setiap segi kehidupan di “rumah” (dunia) milik Tuhan ini agar menjadi semakin baik, indah, nyaman, tertib dan damai. Salah satu segi kehidupan yang menjadi tanggungjawab orang percaya (gereja) adalah segi pendidikan.Metode penulisan ini menggunakan kajian pustaka yang relevan dengan tugas panggilan gereja terhadap pendidikan. Tujuan penulisan ini adalah untuk membantu gereja (baik sebagai lembaga/institusi maupun sebagai individu/ person) untuk merumuskan dan mewujudkan tugas panggilannya dalam bidang pendidikan dengan perencanaan yang matang, pengorganisasian yang rapi dan pelaksanaan yang baik.
