Published: March 2023

Azalea absolute oil is used in the highest quality perfumery liquids production, although because of muddying of perfumery product during the storage process and sediment separation, its wide usage was hold up. In spite of fact that Azalea absolute oil production started long time ago the influence of absolute oil receiving technology regime’s separate factors on the absolute oil productivity and quality was not investigated. The technological regime of receiving absolute oil from Azalea concrete was investigated in details. As a result it was established that concrete should be processed with 96% ethyl alcohol (solute) during 6 hours, the subsequent waxes – during 4 hours, and the alcoholic solutions obtained during the processing of concrete and waxes should be kept for 2 hours at minus 12-150C. It is necessary to coupage and concentrate the alcohol solutions obtained during the processing of concrete and waxes to 10% absolute oil content and delay for 20 days and nights. After a delay, the concentrated solution should be filtered and the solvent transferred. The established technological regime lets an absolute oil to be free from sediment (triterpene alcohols), their existence in perfumery liquids caused muddying and separation of amorphous sediments.

Tea is one of the most consumed beverages, second only to water worldwide. It stands out for its taste, aroma, and other benefits. Tea contains large amounts of phenolic substances with high antioxidant properties. Tsalenjikha green tea was selected for the experimental study. Three types of extracts were chosen: deionized water, ethanol and a mixture of ethanol and water (1:1 ratio). The total phenolic content was determined by the Folin-Chocalteu reagent and antioxidant activity by the FRAP method. The results indicate a high polyphenolic index in ethanol and water-ethanol extract. After that, two types of beverages were made by high antioxidant extracts and alcohol with strength 40O. The ratio was 1:4. After mixing, the antioxidant activity was determined in the prepared beverage and the observation of quantitative change continued for a week. Additionally, green tea extract gave different organoleptic properties to Vodka: changed color, aroma and taste according to the extracts.

Published: March 2023

The role of developed infrastructure in the formation of financial centers is discussed in the article. Cities that have become financial centers differ from others in several main criteria. One of the most important of them is the availability of the appropriate infrastructure. This requires large-scale and high-quality construction of communication and transport systems, administrative buildings, residential houses, hotels, health care facilities, education, recreation, entertainment and other public facilities, as well as numerous specialized financial, stock exchange and banking institutions. In this direction, the city of Istanbul is currently developing very strongly, and after the completion of the construction project of one of the largest financial centers in the world, it is going to compete with the financial centers of New York and London. Despite the incredibly rapid development of the financial centers of Asia and the Middle East, they are still undisputed leaders. The financial center of Chicago is distinguished by a developed infrastructure, which has maintained leading positions in the world for more than a century in the conditions of the greatest competition. In addition, it is necessary to note that a unique construction and architectural project, implemented in Chicago at the end of the 19th century, started the introduction of completely new technologies that are successfully used in the field of construction even today.

Published: March 2023

Azalea plant belongs to the Rhododendron family (Ericaceae), which includes approximately 130 species, about 20 of which are found in the Far East, Siberia and the Caucasus. It is a perennial plant and is distributed in the Northern Hemisphere, the mountains of East Asia and North America. Large massifs of the Azalea plant are found in the wild in Georgia, Ukraine and the Krasnodar Krai (Russian Federation). Plants of this species are rich in various natural compounds: flavonoids, tannins, pigments, toxins, triterpenoids, essential oils and others. The Azalea plant is investigated in order to receive the absolute oil and concrete from its flowers. The influence of solvent, time of flower gathering and flowers crowns components (stems, bowls) on concrete and absolute oil outcome and quality are investigated. According to the research, Azalea extraction is advised to be conducted with petrol in room temperature conditions (18-230C); Azalea flowers should be gathered in the first part of a day during the beginning of blooming period and massive blooming; Azalea flowers should be processed with the stems and bowls – entire raceme. The concrete yield from Azalea flowers in average is 0,33%, and absolute oil yield from concrete in average – 64,5%. The Azalea flower’s concrete organoleptic and physic-chemical properties are studied and it is established that concrete quality indexes totally satisfy concrete demands. Research results were taken into account while working out the Azalea flower processing technology.
Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter
Authors: Me Si Phu , Ravanji Mohammad Hasan , Zarif Mansour Milad , Zabihi Sasan , Bahrani Behrooz
Published: March 2023

The majority of inverter-based resources (IBRs) currently operate as grid-following inverters (GFLIs). These inverters exhibit certain stability issues when integrated in low-strength areas of the grid. To enhance the grid strength in a GFLI-dominant area, virtual synchronous generators (VSGs) are installed. If the VSG and the GFLI are investigated as a paralleled system, despite the benefits brought by the VSG, in some cases, the transient angle instability process, caused by a voltage sag, is accelerated. Therefore, this paper studies the transient angle stability of a paralleled VSG-GFLI system via investigating the voltage at a common bus between the two IBRs. Subsequently, a stable region of the voltage angles of the two IBRs is determined. Based on this region, the stability margin of the paralleled system can be determined and used to quantitatively evaluate the system stability. Moreover, a control loop is proposed to improve the transient stability of the paralleled system. The proposed controller can adaptively reduce the VSG power set-point to avoid a complete failure of the VSG even when no stable equilibrium point exists during a voltage sag. The stability investigation and performance evaluation of the proposed method are conducted in PSCAD/EMTDC and experimentally validated.
Automatic detection of Feature Envy and Data Class code smells using machine learning
Authors: Škipina Milica , Slivka Jelena , Luburić Nikola , Kovačević Aleksandar
Published: March 2023

 A code smell is a surface indication that usually corresponds to a deeper problem in the system. Detecting and removing code smells is crucial for sustainable software development. However, manual detection can be daunting and time-consuming. Machine learning (ML) is a promising approach towards the automation of code smell detection. The first ML-based methods were classifiers trained on feature vectors comprising software metrics extracted by off-the-shelf tools. Determining the optimal set of metrics is a complex problem that requires both ML and software engineering expertise. Recently source code embedding models emerged as a viable feature-inferring alternative. However, their potential is yet to be fully explored. To that aim, we compare state-of-the-art source code embedding models (CuBERT and CodeT5) with the models trained on metrics returned by the CK Tool and RepositoryMiner tools. We focus on detecting the Data Class and Feature Envy code smells within a large-scale, manually labeled, publicly available dataset. After extensive experiments (51 test/train splits), we found that source code embedding models have comparable performances with software metrics, a that they indeed can capture important characteristics of the source code. We discuss our findings in detail in the paper.
CBDC bridging between Hyperledger Fabric and permissioned EVM-based blockchains
Authors: Augusto André , Belchior Rafael , Vasconcelos André , Kocsis Imre , László Gönczy , Correia Miguel
Published: March 2023

The last few years have seen a steep increase in blockchain interoperability research. Most solutions connect public blockchains; hence, the main cross-chain use case is token transfer. By-design platform transparency, tamper-resistance, and auditability make blockchains an infrastructure candidate for Central Bank Digital Currencies (CBDCs), but bridging CBDCs is an important missing piece in general. In this paper, we leverage an asset transfer protocol, ODAP/SATP, to define an extendable and dependable blockchain interoperability middleware that can bridge CBDC from Hyperledger Fabric to EVM-based permissioned blockchains. The key interoperation enabler in the solution is a shared asset definition enforced by both sides of the bridge, accompanied by a mapping between Fabric Identities and Ethereum addresses for Identity management. We implement our design for the CBDC use case utilizing Hyperledger Cactus. Through a preliminary performance evaluation, we show that the underlying ledgers heavily influence the latency of the solution, not the bridging components.
Multi-harmonic modulation in a fiber-optic gyroscope
Authors: Miranda Martin , Kozuma Mikio
Published: March 2023

Optimizing the bias modulation of a fiber-optic gyroscope is crucial to improving its precision. In this study, we propose and demonstrate the use of multiple harmonics of sinusoidal modulation as an intermediate alternative to the widely used modulation methods: sinusoidal and square-wave modulation. We show that this alternative integrates the advantages of each modulation method by providing a smooth modulation that produces a clean, spike-free output and a satisfactory signal-to-noise ratio. By using three harmonics of modulation in combination with a high frequency to reduce thermal phase noise, we obtained an angular random walk of 5.2(2) μdeg/√h and a bias instability of ∼10 μdeg/h.

Authors: Wu Heng , Zhao Fangzhou , Wang Xiongfei
Published: March 2023

Impedance-based method has been increasingly adopted to assess the stability of inverter-based resources (IBRs). To get a better view of the state-of-art and challenges for implementing the impedance-based dynamic analysis, a survey with general/specific questions has been initiated by IEEE Task Force on Frequency-Domain Modeling and Dynamic Analysis of HVDC and FACTS. The feedbacks are collected from universities, national labs, transmission system operators (TSOs), power plant developers, as well as IBR vendors. It is interesting to note that while many common understandings have been established in practices, certain gaps still exist among different stakeholders. This article intends to bridge this gap by sharing a summary of the survey, including questionnaires, responses from different stakeholders, and the analysis of survey results. The challenges for different stakeholders using impedance-based method are identified, which hopefully shed a light on the future research work.

Normalizing Flow based Uncertainty Estimation for Deep Regression Analysis
Authors: Zhang Baobing , Sui Wanxin , Huang Zhengwen , Li Maozhen
Published: March 2023

Uncertainty estimation is a critical component of building safe and reliable machine learning models. Accurate estimation of uncertainties is essential for identifying and mitigating potential risks and ensuring that machine learning systems operate reliably in real-world scenarios. Various approaches, such as ensemble and Bayesian neural networks have been developed by sampling probability predictions from submodels, which is computatinally expensive. Currently, these methods are unable to clearly define the boundary between in distribution (ID) and out-of-distribution (OOD) data. To fill up this research gap, this paper presents a normalizing flow based framework to directly predict parameters of prior distributions over the probability with a neural network, which is capable of effectively distinguishing ID and OOD data for regression problems. The posterior distributions learned by the proposed model accurately model uncertainties for OOD data from ID data without requiring OOD data at training time. This approach has shown promising results in a number of applications, including image depth estimation and image adversarial attacks.
Photons distributing as waves --- New mystery of double slit experiment
Authors: peng hui
Published: March 2023

The classical interpretation of Young’s double slit experiment is that, before and after passing through the diaphragm of the double slit, the light behaves as waves. Feynman called the double slit experiment “the only mystery [of quantum mechanics]. We have shown for the first time that in the classical wave experiments: (1) Particle patterns, which are non-interference patterns indicating the particle nature of light, are near the diaphragm, and Interference patterns are near the screen; (2) Particle patterns evolve to Transition patterns that are also non-interference patterns, and, finally, evolve to Interference patterns; (3) Postulates of lens for utilizing lens in wave experiments.

The Roots of Maxwell’s A Dynamical Theory of the Electromagnetic Field
Authors: Pelosi Giuseppe , Selleri Stefano
Published: March 2023

The formulation of Maxwell’s equations completely defines the connection between the electric field and the magnetic field, definitively unifying electricity and magnetism and at the same time providing a theoretical synthesis of all the experimental phenomena connected to these areas. In his revolutionary 1864 memoir where J.C. Maxwell presented his equations, he cites a handful of scientists, which were at the basis of his Theory. This book, in its first part, presents an insight on all these latter scientists, reconstructing the scientific network behind Maxwell’s unification and, in the second part, focuses on the Italians in such a network: Ottaviano Fabrizio Mossotti and Riccardo Felici, with a further insight on the connections between Maxwell and Italy and, in particular, Tuscany.

Authors: Karpyak Mariya O. , Herman Lyudmyla T. , Kostyshyna Anna I.
Published: March 2023

Human potential is the defining strategic resource of any state and the nation’s greatest wealth. Today, it is the basis for the growth of the state’s capacity both in the domestic and international markets and, in general, the basis for the socio-economic progress of society. The importance of human potential as the highest value of society requires awareness of the need for its preservation, rational use, and effective reproduction, which is the key to the harmonious development of socio-economic systems. Since the problem of the development of human potential has long been the subject of discussions by many leading domestic and foreign researchers and today, there is no single approach to the interpretation of this category, it is appropriate to consider the results of major scientific studies related to this issue. The available interpretations of the “human potential” category are extremely diverse but usually, they take into account two aspects: the resource component of human potential - a set of certain resources that can be used to achieve certain goals and the presence of certain circumstances and opportunities. Thus, the content of the category of human potential and the process of evolution of this concept in the plane of scientific research are investigated in the article as a result of the analysis of the major scientific studies related to this issue. The article substantiates that this concept is broader than the category of labor resources or human capital and, as a result, includes the latter. The problems of preservation and development of human potential as the main strategic resource of the state and the greatest wealth of the nation are outlined. The author’s interpretation of the content of the human potential category, as well as the concept of human potential capitalization, is argued. The main approaches to the formation of the structure of human potential are considered, and the vision of its main components is proposed based on the experience of leading scientists-researchers.

Sustainable soil stabilization: the use of waste materials to improve the engineering properties of soft soils
Authors: Chmielewska Iwona , Gosk Wojciech
Published: March 2023

One of the biggest challenges of recent civil engineering is the need to make it sustainable by implementing environmentally friendly and cost-effective solutions. The search for new materials and technologies is an important and current issue also in the strengthening of soft soils. In the soft soil stabilization process, conventional materials (cement and lime) are being replaced by waste materials, such as stone slurry waste, spent coffee grounds, rice husk ash, crushed waste concrete and glass, natural fibers, sawdust, waste tire rubber and plastic waste materials. Appropriate waste admixture content contributes to soil reinforcement by reducing compressibility and increasing maximum density and shear strength. The application of waste as an admixture is an economically and ecologically beneficial method of soil improvement. It eliminates the cost of materials and helps to reduce the problem of waste disposal, which is sometimes very expensive and problematic. The study aims to analyze the effect of waste materials on improving the physical and mechanical properties of soils based on the research results presented in the literature.

TRADITIONS OF COMEDY “GEORGE DANDIN, OR THE FOUGLED HUSBAND” BY J.-B. MOLIERE IN THE DRAMATURGY OF A.P. CHEKHOV
Authors:   Ural State Pedagogical University, Kubasov A. V.
Published: March 2023

The article reveals the archetypal image of a simpleton. One of its variations is the type of the deceived husband. He is most fully represented in Molière’s comedy Georges Dandin, or the Confounded Husband . The expression from the comedy “Tu l’as voulu, George Dandin, Tu l’as voulu” (“You yourself wanted it, Georges Dandin, you yourself wanted it”) has become a phraseological unit. The Russified image of Molière’s confounded husband is paired and presupposes the presence of a spouse. In Chekhov’s dictionary, the concepts of “wife” and “spouse” are not identical. The most adequate representation of the confounded husband is presented in the writer’s vaudevilles. In large plays, an ambivalent combination of dramatic intonation with a comic beginning is found.

formación histórica de Quito
Authors: Zhingre Raúl
Published: March 2023

En muchas cosas, Quito resulta frágil, obscura y desconocida, sobre todo cuando se trata del origen indígena en su escala preinca. No obstante, en otros campos es evidente su influencia en lo que hoy es América Latina, por ejemplo, cuando se transformó en eje del Imperio del Tahuantinsuyo. Para los incas, Quito era un centro de articulación interregional. Este rol continuó con los españoles, que fundaron aquí una urbe colonial en 1534. Y a principios del siglo XIX se fundó Ecuador y se estableció a Quito como su capital.Así, Quito es plural, milenaria y multiétnica, siendo esto su formación histórica.

Plasmonic nanotechnology for photothermal applications – an evaluation
Authors: Indhu A R , Keerthana L , Dharmalingam Gnanaprakash
Published: March 2023

The application of plasmonic nanoparticles is motivated by the phenomenon of surface plasmon resonance. Owing to the tunability of optothermal properties and enhanced stability, these nanostructures show a wide range of applications in optical sensors, steam generation, water desalination, thermal energy storage, and biomedical applications such as photothermal (PT) therapy. The PT effect, that is, the conversion of absorbed light to heat by these particles, has led to thriving research regarding the utilization of plasmonic nanoparticles for a myriad of applications. The design of conventional nanomaterials for PT conversion has focussed predominantly on the manipulation of photon absorption through bandgap engineering, doping, incorporation, and modification of suitable matrix materials. Plasmonic nanomaterials offer an alternative and attractive approach in this regard, through the flexibility in the excitation of surface plasmons. Specific advantages are the considerable improved bandwidth of the absorption, a higher efficiency of photon absorption, facile tuning, as well as flexibility in the synthesis of plasmonic nanomaterials. This review of plasmonic PT (PPT) research begins with a theoretical discussion on the plasmonic properties of nanoparticles by means of the quasi-static approximation, Mie theory, Gans theory, generic simulations on common plasmonic material morphologies, and the evaluation processes of PT performance. Further, a variety of nanomaterials and material classes that have potential for PPT conversion are elucidated, such as plasmonic metals, bimetals, and metal–metal oxide nanocomposites. A detailed investigation of the essential, but often ignored, concept of thermal, chemical, and aggregation stability of nanoparticles is another part of this review. The challenges that remain, as well as prospective directions and chemistries, regarding nanomaterials for PT conversion are pondered on in the final section of the article, taking into account the specific requirements from different applications.

Published: March 2023

Internet of Things is a highly applicable technology due to its versatility in areas such as agronomy, health applications, and industry. Besides, portability makes these devices affordable. IoT development boards communicate through Wi-Fi transmitted messages via the Internet, depending on the inner workings of the IoT development board, energy consumption can vary in such transmission. Furthermore, this consumption could change if the board is powered by different power supplies and the quantity of Wi-Fi transmitted messages. This paper provides a methodology to acquire an energy profile when sending data (byte) using Message Queue Telemetry Transport (MQTT) protocol on DEVKIT V1 NodeMCU-32 (ESP32) development board. Three different power supplies were used for the board, a 3.7 LiPo Battery, 5v usb Power bank and 9V NiMh rechargeable battery. The higher current consumption obtained was using a 3.7 battery, followed by 5v and the lowest current consumption was when using 9v. However, results demonstrate that when using the 9v power supply the energy consumption is two times higher than using 3.7v. Therefore, the best voltage source for transmission and energy consumption using a NodeMCU-32 development board will be 3.7 volts.

This study focuses on the effects of Korean writing instruction in the context of an English-medium instruction (EMI) policy. It specifically investigates the changes of students’ motivation and self-efficacy through a semester-long learning and participation in the class. The dataset consisted of questionnaire responses about writing motivation, self-efficacy, and perceptions of English- and Korean-medium instruction (KMI) by college students learning Korean writing. Surveys were conducted at the beginning and end of two semesters. The analyses indicate that writing motivation (both extrinsic and intrinsic) and self-efficacy statistically significantly increased after the writing course. While positive correlations between intrinsic and extrinsic motivation, intrinsic motivation and self-efficacy, and extrinsic motivation and Korean-medium instruction were found at the beginning of each semester, post-class data additionally showed a negative correlation between KMI and EMI. These results are discussed to highlight the contribution of Korean writing instruction in the context of EMI to increased student perception of KMI as well as their writing motivation and self-efficacy.
A Study of Educational Methods for Determining the Topic of Academic Writing for Foreign Students: Through the Expansion of the KWL Model
Authors:   Korean Association for Literacy, Jang Chaerin
Published: March 2023

This study aimed to propose an educational method for determining the topic of academic writing for foreign students using the KWL(Know-Want-Learn) model. To this end, an expanded model called KWLC(Know-Want-Learn-Compare) was presented by analyzing the subject-determining teaching method and previous relevant studies. The proposed model was applied to three classes of college writing in the spring and fall semesters of 2022, and the results were analyzed through case studies. The results were as follows. First, the KWLC model made reading and writing easier through critical thinking. Second, the contents written in stage C played a decisive role in deriving the topic. Third, through stage C, thinking developed in the direction of paying attention not only to the “gap in knowledge” and “gap in thinking” but also to the “gap in objects,” enabling the reader to develop an extended theme beyond the subject of the given text. Fourth, KWLC was helpful in deriving specific and creative themes. It is expected that the KWLC instructional model of this study can be actively used to help the student realize the subject from their own perspective through critical and integrative thinking.

A Study on the Relationship between ‘Other-Me’ and Educational Relationships: Focusing on the philosophy of Lévinas and Ricoeur
Authors:   Korean Association for Literacy, Chun Chongyoon
Published: March 2023

The research methodology adopted in this article is to replace the educational relationship between teacher and student with ethical relationships between others and me. This stems from the view that ethical relationships are more fundamental than educational relationships. First, my relationship with others is based on a personal and collective ethical perspective. From this ethics, moral and ethical subjects can establish their own views on others and the world. Second, this ethical and philosophical relationship is useful in educational practice, especially teacher-student educational relationships. Therefore, the contribution of this study is twofold. It is the aspect of comparative analysis of Lévinas and Ricoeur’s philosophy of ‘others-me’ and the aspect of attempting philosophical reconciliation between ethical and educational relations. The goal of this study was to derive and propose a new educational relationship through an in-depth examination of ethical relationships. As a result, the education of others based on Lévinas’ philosophy and the education of mutual recognition based on Ricoeur’s philosophy were proposed. First, in the pedagogy of others, three themes were emphasized. 1° Double asymmetry of teacher-student relationship, 2° Relationship of domination and subjugation. 3° Pedagogy of the other as possibility education. Through these three elements, the characteristics of Lévinas’ pedagogy were discussed. Second, the pedagogy of mutual recognition also dealt with three topics. 1° Self-affirmation and the teacher-student educational relationship. 2° Caring and teacher-student educational relationships. 3° Mutual Recognition and Educational Relationships. These three themes are elements that represent Ricoeur’s pedagogy.
Research on the possibility of aesthetic communication in Platon’s Symposium
Authors:   Korean Association for Literacy, Kang Ji Eun
Published: March 2023

This study tried to analyze Plato’s 『Symposium』 as ‘aesthetic communication’. In fact, it goes without saying that most of Plato’s writings consist of dialogue, and that the form of discussion itself is communication. In communication studies, there is an example where Plato was studied as a pioneer of communication. Michael Deuce, Mary Brown, 『Plato’s Shadow』, Communication Books, 2012. However, the research is a communication study from the level of rhetoric. However, there are few examples of philosophical analysis of the dialogue form and content of texts in Plato’s studies so far. Not all Plato’s texts have a correlation between dialogue form and content. However, at least as far as 『Symposium』, dialogue and content have a close correlation. The author tried to approach it with the concept of ‘aesthetic communication’. The idea of aesthetic communication, which started from Kant’s aesthetics, is based on ‘common sense’. All human beings feel and admire beauty through the operation of reason and imagination in front of a beautiful object. However, the wonder and wonder of this beauty wants to share it with the people around it through the medium of ‘common sense’, and they actually do share to form a community. Hannah Arendt, who inherited this common sense of Kant as her own philosophy, develops Kantian aesthetics into a political philosophy. The author tried to read Kant's mechanism of aesthetic communication in Plato’s 『Symposium』. Plato cannot be Kant. However, in Plato’s 『Symposium』, both the personal eros of ancient Greek society, aphrodisia (sexual pleasure), and the political life, the eros of truth, are embodied. According to the author’s analysis, the communication of 『Symposium』 has the same historical tradition as Kant’s aesthetic communication about beauty. Therefore, in this study, I tried to analyze what conditions Plato’s 『Symposium』 have as an aesthetic communication and to reveal the possible reasons.
