Definitions and Paradigms of European Security
Authors:   Institute of Europe of Russian Academy Sciences, Sindeev Alexey
Published: July 2021

Modern political activity develops on the basis of disclosure and partial correction of previously developed algorithms and approaches, which significantly increases the practical significance of the historical and political science methodology, with the help of which it is possible to identify the content, directions of evolution, the prospects for changing traditional models and phenomena. The article attempts to study the essence of the security phenomenon in the context of currently emerging paradigms. The working hypothesis was the assumption that the transformational processes of the 1970’s, which subsequently experienced a «security swing», their elements, system hierarchy and logic of representation continue to persist in the current Western model, since multi-factor and successful transformations slow down change. As a result of the study, disparities in the substantive definition of security goals, contradictions between political goals and processes were revealed, a working hypothesis was confirmed, and problems that require further study, including through the expansion of the empirical base, were outlined. The article is written mainly on the materials of the three «White Papers» of the Bundeswehr. It is controversial in nature, but already at this stage of the study has a practical value, reflected in four recommendation-prognostic conclusions.

Published: July 2021

In arthroscopic shoulder surgery, general anesthesia (GA) is the common method of anesthesia. Recently, the combined usage of interscalene brachial plexus block with general anesthesia (ISB/GA) was reported to have a lower incidence of adverse side effects than GA alone. However, to date, no study has compared stress and inflammatory responses between these two methods. Since stress and inflammatory responses are critical on intraoperative management and postoperative recovery, we integrated the laboratory and clinical methods and compared the stress and inflammatory factors, such as epinephrine, norepinephrine, glucose, lactate, inflammatory factors tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), as well as the clinical outcomes to determine whether ISB/GA provides an advantage on stress and inflammatory inhibition. Data showed that ISB/GA resulted in significantly lower epinephrine, norepinephrine, and glucose levels perioperatively. Six hours after operation, the TNF-α and IL-6 levels were also significantly lower in the ISB/GA group. ISB/GA patients had lower blood pressure, a more stable heart rate, lower visual analog scale score, and less opioid consumption during and after surgery. Our results indicate that ISB/GA is a better choice for arthroscopic shoulder surgery, owing to less stress and inflammatory responses during and after operation, which provides better clinical outcomes. Therefore, we recommend ISB/GA as a preferred anesthesia method for arthroscopic shoulder surgery.

Higher education is used to nurture advanced specialized training; however, nurturing innovative and practical ability is hard to put into practice. In experimental teaching, hands-on activities are offered to promote studentsâ€™ practical ability, leading to better-specialized training. This study aims to explore studentsâ€™ engagement, communication and collaborative skills, as well as learning outcomes by integrating hologram experiments into a university course. Eight university students participated in this study for 3-weeks. Hologram theory was taught in the first week, while in the second and third weeks, the students performed experiments. Pre- and post-test data were collected using questionnaires during the first and last week, respectively. Besides, in-depth interviews were conducted. The findings revealed that students were able to interact with each other, which promoted their engagement in experimenting. Moreover, teammates were able to communicate and collaborate effectively, which led to higher achievement in their learning outcomes. Despite the benefits reported, opportunities and challenges were identified for teachers and students to be aware of during hologram experiments to help them develop creative skills and develop an understanding of holography concepts.

Authors: Kartimi K. , Gloria R. Y. , Anugrah I. R.
Published: July 2021

The COVID-19 outbreak has made many countries decide to close schools to prevent the spread, including Indonesia. This leads to online distance learning. Furthermore, online distance learning is carried out by teachers suddenly without prior preparation. Therefore, the teachers' Technological, Pedagogical, Content Knowledge (TPACK), and attitude to conduct online distance learning are crucial. Thus, this study intends to identify chemistry teachers’ TPACK and attitude in online distance learning during the COVID-19 outbreak. Purposed-design survey method was used with 109 participants in Java, Indonesia. The data were collected using online questionnaires then analyzed quantitatively using factor analysis and qualitatively based on the teachers’ response to online distance learning during the COVID-19. The questionnaire used consisted of 36 close-ended statements with a Likert scale and 10 open-ended questions to find out challenges and opportunities for implementing chemistry online distance learning. The results show that the teachers try to adapt their way of teaching and assessment by using various technology platforms for online distance learning. The attitude and TPACK of the teachers tend to be positive in responding to online distance learning even though some senior teachers have a negative tendency to the aspects of attitude and technological knowledge. It can be implied that training in the use of various technologies, and enhancement of chemistry teachers’ TPACK skills are needed to produce better online distance learning. These results are expected to provide an overview of the challenges and opportunities of online distance learning in chemistry during or beyond the COVID-19 outbreak.

Published: July 2021

STEM teaching approach has attracted the attention of science educators as a panacea in addressing the deteriorating interest in STEM learning. However, the impact of STEM teaching approach on students’ achievement is scarcely discussed. Thus, this study aimed to explore the impact of integrating Science and Engineering teaching approach on the achievement of students. This meta-analysis was conducted systematically on articles published between January 2000 to January 2020 which were retrieved from five databases (EBSCOhost, Emerald, Scopus, Web of Science and ERIC).  Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were applied to ensure a rigorous selection of the desired research articles. The data were then assessed using two online statistical effect size calculators. A total of 14 effect sizes were calculated. The overall mean effect size obtained was of high effect (es=2.61).  The Engineering Design Process (EDP)(es=3.26, high effect) was the most effective teaching approach in enhancing students’ understanding, as opposed to design-based learning.   An implication of the study is that EDP should be the basis for other teaching approaches in SE. Solving and creating tasks encourage application of concepts that then lead to enhancement of achievement.

One Step Closer to Understanding Motivation in Scientific Education: The Incorporation of Science Textbooks as a Predictor, Together with Motivational Climate and Basic Psychological Needs
Authors: Romero R. , De las Heras MÂª. A. , SÃ¡enz-LÃ³pez P. , FernÃ¡ndez Ozcorta E. J.
Published: July 2021

Studentsâ€™ increasing lack of interest in science has led to a disturbing situation that compels us to continue researching educational motivation, in this line, and within the framework provided by self-determination and achievement goal theories. The great importance of this variable can be attributed to its relevance in classes and its competence-related nature, which in principle makes it a motivating resource, as is the case with science textbooks. In particular, this study provides an in-depth understanding of motivation using various motivational predictors, while incorporating the motivational competence relevance of science books. One thousand students between the ages of 10 and 14 years participated. The research instrument used was a questionnaire consisting of 4 scales that measured the motivational competence relevance of science books, the task-oriented motivational climate, the basic psychological need for competence and the intrinsic motivation. Data were analyzed using correlation analysis and a structural equations model. The results showed that, among other aspects, motivation is influenced by competence, while competence is influenced by the task climate and the motivational competence relevance of science books. These findings suggest that in order to increase studentsâ€™ intrinsic motivation, teachers must create a task-oriented climate, emphasize the value that student should attribute to science books from a motivational competence perspective, and satisfy the need for competence.

Some results concerning localization property of generalized Herz, Herz-type Besov spaces and Herz-type Triebel-Lizorkin spaces
Authors: Djeriou A. , Heraiz R.
Published: July 2021

In this paper, based on generalized Herz-type function spaces $\dot{K}_{q}^{p}(\theta)$ were introduced by Y. Komori and K. Matsuoka in 2009, we define Herz-type Besov spaces $\dot{K}_{q}^{p}B_{\beta }^{s}(\theta)$ and Herz-type Triebel-Lizorkin spaces $\dot{K}_{q}^{p}F_{\beta }^{s}(\theta)$, which cover the Besov spaces and the Triebel-Lizorkin spaces in the homogeneous case, where $\theta=\left\{\theta(k)\right\} _{k\in\mathbb{Z}}$ is a sequence of non-negative numbers $\theta(k)$ such that \begin{equation*} C^{-1}2^{\delta (k-j)}\leq \frac{\theta(k)}{\theta(j)} \leq C2^{\alpha (k-j)},\quad k>j, \end{equation*} for some $C\geq 1$ ($\alpha$ and $\delta $ are numbers in $\mathbb{R}$). Further, under the condition mentioned above on ${\theta }$, we prove that $\dot{K}_{q}^{p}\left({\theta }\right)$ and $\dot{K}_{q}^{p}B_{\beta }^{s}\left({\theta }\right)$ are localizable in the $\ell _{q}$-norm for $p=q$, and $\dot{K}_{q}^{p}F_{\beta }^{s}\left({\theta }\right)$ is localizable in the $\ell _{q}$-norm, i.e. there exists $\varphi \in \mathcal{D}({\mathbb{R}}^{n})$ satisfying $\sum_{k\in \mathbb{Z}^{n}}\varphi \left( x-k\right) =1$, for any $x\in \mathbb{R}^{n}$, such that \begin{equation*} \left\Vert f|E\right\Vert \approx \Big(\underset{k\in \mathbb{Z}^{n}}{\sum }\left\Vert \varphi (\cdot-k)\cdot f|E\right\Vert ^{q}\Big)^{1/q}. \end{equation*} Results presented in this paper improve and generalize some known corresponding results in some function spaces.

Detailed clinical assessment of the central nervous system involvement in SARS-CoV-2 infection is relevant due to the low specificity of neurological manifestations, the complexity of evaluation of patient complaints, reduced awareness of the existing spectrum of neurological manifestations of COVID-19, as well as low yield of the neurological imaging.

The aim. To reveal the patterns of central nervous system involvement in COVID-19 and its pathogenesis based on clinical data.

Among more than 200 primary literature sources from various databases (Scopus, Web of Science, RSCI, etc.), 80 sources were selected for evaluation, of them 72 were published in the recent years (2016-2020). The criteria for exclusion of sources were low relevance and outdated information.

The clinical manifestations of central nervous system involvement in COVID-19 include smell (5-98% of cases) and taste disorders (6-89%), dysphonia (28%), dysphagia (19%), consciousness disorders (3-53%), headache (0-70%), dizziness (0-20%), and, in less than 3% of cases, visual impairment, hearing impairment, ataxia, seizures, stroke. Analysis of the literature data revealed the following significant mechanisms of the effects of highly contagious coronaviruses (including SARS-CoV-2) on the central nervous system: neurodegeneration (including cytokine- induced); cerebral thrombosis and thromboembolism; damage to the neurovascular unit; immune-mediated damage of nervous tissue, resulting in infection and allergy-induced demyelination.

The neurological signs and symptoms seen in COVID-19 such as headache, dizziness, impaired smell and taste, altered level of consciousness, bulbar disorders (dysphagia, dysphonia) have been examined. Accordingly, we discussed the possible routes of SARS-CoV-2 entry into the central nervous system and the mechanisms of nervous tissue damage.

Based on the literature analysis, a high frequency and variability of central nervous system manifestations of COVID-19 were revealed, and an important role of vascular brain damage and neurodegeneration in the pathogenesis of COVID-19 was highlighted.

Authors: Wang Jian , Zhang Hui , Jiang Huashan , Pan Lin
Published: July 2021

Permeability is one of the key parameters in reservoir property studies. The existing well log interpretation models could not predict the permeability accurately due to the complexity and ambiguity of well logging curves, and the prediction results may demonstrate significant contradictions with the production data. Based on the comprehensive analysis of cores, well logs, laboratory tests, and thin section observations, we take the first member of Liushagang Formation (L1) in Weizhou 11-1N Oil Field as the target, and select median grain size, porosity, and resistivity to establish a multiple nonlinear regression interpretation model of permeability. The accuracy and applicability of this model is validated by the laboratory test data and oil production performance. This permeability interpretation model is easy and practical to operate. Furthermore, it bridges the geological characteristics and the production performance.

Published: July 2021

Polish-Ukrainian interstate relations covering the period beginning with the presidency of A. Duda and followed by the victory of the radical-right political party «Law and Justice» in the parliamentary elections have been analyzed. The main attention is focused on the key trends of their development and the factors affecting them. The consequences to the relations between the two countries of the emphasis that official Warsaw makes on issues of the common past, mainly Volyn tragedy, the interpretation of which on Ukrainian and Polish sides are far from identical, have been found out. The attention is drawn to the adoption of the law «On the legal status and honoring the memory of the fighters for Ukraine’s independence in the twentieth century» by the Verkhovna Rada of Ukraine (April 9, 2015), wich caused an active discussion on the part of the official Warsaw, as well as to the similarly met in Ukraine resolution of the Sejm «On establishing the 11 of July the Memorial Day of Poles, the victims of genocide committed by the UPA» (22 July 2016). The provocations on both sides of the border organized by the interested in worsening of the relations between Warsaw and Kyiv have been highlighted. However, іt has been proven that despite the tensions caused by the often highprofile steps of the Polish and Ukrainian authorities, the strategic partnership between the two countries remains relevant. And while the first official visit of President A. Duda t to Ukraine took place only in December of 2015, the fact is, that the presence of the Polish head of state at the ceremony in Kyiv on the occasion of the 25th anniversary of Ukraine’s independence on August the 24th of 2016 only six months after the election is an eloquent testimony of the importance of cooperation with Ukraine for the official Warsaw. Precisely then the presidents of the neighboring states signed a Joint Declaration on Strategic Partnership.
Transformation of Positions of the Political Parties of the Federal Republic of Germany Towards Eastern European Policy (2005-2017)
Authors:   the Institute of History of Ukraine, the National Academy of Sciences of Ukraine, Kharlan Hanna
Published: July 2021

The article researches conceptual approaches of the German political parties regarding the prospects of interaction with the Eastern European states in 2005-2017. Positions of political forces of the Federal Republic of Germany are characterized by the degree of impact of one or another party to the course of political life. The priorities in the Eastern European policy of the six main parties (CDU/CSU, SPD, FDP, “Alliance 90/The Greens”, “Left”, “Alternative for Germany”) during the reign of the second “grand” Christian-liberal coalition, and the third “grand” coalition led by Federal Chancellor A. Merkel are analysed. Almost all political forces stood for Germany’s active participation in the process of European integration. Instead, there were significant differences in the issue of relations between Germany and the Eastern European states and prospects of their joining the European Union. The CDU/CSU position was based on solving traditional problems of maximum security in Europe. The SPD strategy was based on the fact that Russia, as well as during the confrontation between blocks in the Cold War, should be the nucleus of the East European policy of the FRG. The views of the FDP in general are in line with the positions of the CDU / CSU. The “Alliance 90/The Greens” stressed the need for a pan-European security system and the further implementation of the European Neighbourhood Policy. The rhetoric of the “Left” and the representatives of the “Alternative for Germany” party was plainly pro-Russian. The author concludes that the Revolution of Dignity, the signing of the Association Agreement, the annexation of Crimea and the war in the East of Ukraine have shown the need for a revision of orientations in the Eastern European politics and the development of fundamentally new forms of interaction between Germany and the Eastern European states. To a certain extent, this trend has been reflected in the program documents and polemics on the eve of the Bundestag 2017 elections.

Perkembangan ilmu hukum tidak dapat dipisahkan dengan putusan hakim. Bahkan putusan hakim menjadi motor penggerak dinamika diskursus hukum. Tidak jarang, putusan-putusan hakim ramai untuk dibahas, didiskusikan bahkan untuk dikritisi sehingga menjadi episentrum pembaruan hukum. Adagium judgc made law yang menjadi ciri sistem hukum anglosaxon atau hakim sebagai kreator hukum (legal creator) telah melegitimasi nalar bahwa hakimlah yang berhak untuk membuat hukum, bukan raja atau penguasa karena dengan berhukum kepada sesuatu yang sudah tertulis ternyata belum mampu mendatangkan keadilan akibat proses distorsi antara idealita dan realita. Aliran filsafat realisme hukum membongkar keraguan itu semua dengan menempatkan empirisme dan pragmatisme putusan hakim sebagai jawaban akan ketidakadilan.

This virtual instrumentation system based on Arduino and LabVIEW aims to detect the water level using a water level sensor. The water level sensor used to measure the water level is the Funduino type. This sensor and the buzzer module are connected to the Arduino Uno to transmit data to LabVIEW. When the water has reached a certain height, this sensor will detect the water level. When the water has reached the set point, this sensor will sound a buzzer as a sign that the water is full. Based on the experimental results, it is found that the tension value affects the volume of the experiment site. Where the greater the volume used will produce a large voltage, and vice versa. Furthermore, the graph results obtained that are still away from the linearity of a regression function with a value of y = 0.0079x + 1.8561 and R² = 0.4298.

ABSTRACTAlthough reading aloud is an old teaching strategy, its relevance has been vouched by research from time to time. The present study aimed to critically review experts' opinions and results of previous research on the definition and characteristics of reading aloud and its benefits for young children in the EFL contexts by employing George’s (2008) model of literature review. The review revealed that the teacher plays the most crucial role in reading aloud, acting as the bridge between the text and the student's comprehension. A good design of reading aloud demands the teacher’s competence in choosing the text to meet the students’ interest and level; planning the tempo of the reading and the pauses to pose questions and comments; and making connections with the text and the children. Reading aloud benefits children’s English regarding their vocabulary, pronunciation, comprehension, listening skills, reading skills, speaking skills, communicative skills, and motivation, literacy, and critical thinking skills. These results imply that reading aloud is still relevant to be implemented nowadays because of the benefits it brings to children’s English. ABSTRAKMeski sering dianggap metode lama, membaca nyaring memberi banyak manfaat. Artikel ini bertujuan untuk melakukan kajian kritis terhadap pendapat ahli dan penelitian terdahulu mengenai pengertian, ciri khas, serta manfaat membaca nyaring, dengan mengikuti model penelitian kajian pustaka George (2008). Diungkapkan bahwa guru menjadi penentu kesuksesan kegiatan membaca nyaring sebagai jembatan yang menghubungkan siswa dengan teks yang dibaca. Kegiatan membaca nyaring bergantung pada kemampuan guru untuk memilih teks yang sesuai dengan minat dan kemampuan siswa, serta merancang proses pembacaan terkait tempo dan penempatan jeda untuk memberi komentar, bertanya, maupun membuat kaitan-kaitan antara teks dan siswa. Ahli dan penelitian terdahulu berpendapat bahwa kegiatan membaca nyaring berkontribusi secara positif terhadap siswa terkait pembentukan kosakata, pelafalan, pemahaman, keterampilan mendengar, membaca, berbicara, dan berkomunikasi, serta motivasi, literasi, dan kemampuan berpikir kritis berkomunikasi mereka. Jadi, membaca nyaring sangat relevan diimmplementasikan pada jaman sekarang karena kegiatan ini sangat positif untuk perkembangan Bahasa Inggris siswa.

Kokosanolide A (1), from the seeds of Lansium domesticum Corr. cv Kokossan, has been shown strong cytotoxic activities (IC50 = 8.62 μg/mL) against MCF-7 breast cancer cells. The aim of this work was to study the molecular interactions of kokosanolide A and kokosanolide C with the Estrogen Receptor α (ERα) using computer-aided drug design approaches. Molecular docking using Autodock Vina (open-source software PyRx 0.8) was employed to explore the modes of binding of kokosanolide A (1) and kokosanolide C (2) with ERα. Compounds 1 and 2 showed strong bond-free energy (-8.8 kcal/mol and -8.7 kcal/mol) to ERα. These two compounds have a molecular mechanism to inhibit ERα in breast cancer cells.

The use of bio-concrete is increasing in the present day context and researchers are working on strength and durability characteristics of concrete using bacteria species which have shown calcite precipitation. Three different species of bacteria namely P. Fluorescence, B. Pumilis and B. Subliis that have calcite precipitation properties have been investigated in this study. The investigations were carried first on cement mortar (CM) cubes using these three bacteria species suspension of 20%; 40% and 60% having colony forming units P. Fluorescence (108 CFU/ml), B. Pumilis (106 CFU/ml) and B. Subtilis (108 CFU/ml) respectively. The 40% suspension in all the three cases has shown increased compressive strength as compared to 20% and 60%. The compressive strength measured showed increase (CS) of 18%; 12% for P. Fluorescence; B. Subtilis and decrease of 35% with B. Pumilis respectively. B. Subtilis with optimized 40% suspension having CFU 10x108/ml showed 4.32% ; 5.56%; and 3.81% increase in CS of CC cubes with 3 days; 7 days and 28 days respectively and 5.92% overall increase in CS of CC cubes as compared to the 3 days CS of control cube.

Introduction: Mechanical jaundice (MJ) or bile duct blockage occurs when the bile ducts' patency is impaired, and the bile flow has stopped. One of the main pathogenetic factors developing complications with MJ is immune system imbalance, particularly its phagocytic link. The purpose of the study was to understand neutrophils' functional activity dependence with different blood bilirubin levels in men with mechanical jaundice.
Methods: Forty-seven middle-aged men with mechanical jaundice were divided into three groups depending on the bilirubin levels in their blood: less than 60 μmol/L (n = 10), 60 – 200 μmol/L (n = 20), and more than 200 μmol/L (n = 17). The control group consisted of 50 practically healthy men of the same age. The neutrophils' functional state was assessed using the methods of spontaneous and induced luminol-dependent chemiluminescence of neutrophils.
Results: In the group of patients with mechanical jaundice and a bilirubin level of less than 60 μmol/L, there was an increase in the values of T max spontaneous by 96%, I max spontaneous by 44.81%, S spontaneous by 224.6%, T max induced by 19.9%, I max induced by 13.5%, and S induced by 140.3%. In the group with bilirubin levels from 60 – 200 μmol/L, there was an increase in the values of T max spontaneous by 86.8%, I max spontaneous at 47.7%, S spontaneous at 204.6%, I max induced at 28.3%, S induced at 445%, and activation index at 70%. The group with bilirubin levels more than 200 μmol/L showed an increase in the level of T max spontaneous by 85.9%, I max spontaneous by 53.4%, S spontaneous by 927.3%, I max induced by 28.6%, S induced by 1045%, and activation index by 92.3% compared with the control values. The intergroup differences were found in S spontaneous levels, which were higher in the group with more than 200 μmol/L bilirubin levels compared with the 60 – 200 μmol/L group and less than the 60 μmol/L groups by 216.9% and 237.3% respectively.
Conclusion: The revealed changes characterize the functional activity of neutrophils' increase with an increase in the bilirubin levels in patients with mechanical jaundice.

This study aims to describe the implementation of integrated quality strategic management of Islamic education perspective. The method used in this research is a literature study by collecting (material materials) sourced from various books, journals, and other sources. The results of the study indicate that the application of strategic management of integrated quality of Islamic education perspective is that the existence of Islamic educational institutions will be advanced and qualified if the management system implements TQM which in its operation is full of the concept of ihsan as a whole. The implementation of TQM must of course be preceded by quality planning or ihsan planning. The planning is actually an application of intentions or something to be realized and desired. Then this quality planning is broken down in benchmarking. Benchmarking is an activity to set standards, both processes and results to be achieved within a certain period. For practical purposes, the standard is reflected from the existing reality.
