Industrial areas are typically associated with hazardous levels of air pollution to human health and the environment. The growing number of factories in the area poses an ever-greater threat to the surrounding communities. One of the several incidents pointing to poor air quality in the industrial region is the severe air pollution incident that occurred in Pasir Gudang in June 2019 which brought adverse health impacts to nearby schoolchildren. This study intended to ascertain the role of meteorological factors and impacts on the dispersion of air pollution in the Pasir Gudang Industrial Area at the time of the occurrence. The air pollution distribution patterns were predicted using a trajectory-geospatial method, the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model and Geographic Information System to account for the impact of the monsoon by determining which areas might be hit the worst as the shifted of monsoon seasons. Based on the results, the forward-air mass trajectories showed direct influence by the wind changes in monsoon seasons (Southwest Monsoon, Northeast Monsoon, and Inter-Monsoon). The geospatial maps showed the potential areas affected by the air pollution incident were highly distributed within 1 km, associated with lower dispersion of air pollution at 1000m above ground level height. The findings can serve as a guideline for local authorities in decision-making to develop better standard operating procedure in managing future air pollution threats and to improve industrial location planning in reducing air pollution impacts on the surrounding area.

Online shoppers often have to find reference conversion by manual method, standalone systems, asking sales agents, and browsing the internet. However, these methods that did not provide fast and seamless information on size and fit, and what more by different brands. This study was conducted to identify user requirements for shoe sizing and fitting based on standard size conversion (US, UK, Euro), brand and type. A survey (n=62) was conducted with online shoppers to determine functional and non-functional requirements for the shoe size and fit recommendation mobile application. Subsequently, a mobile application was developed based on the output, followed by 15 user satisfaction tests (n=50) to assess its quality using 9 task scenarios. An interview was then conducted to obtain richer user feedback. The analysis showed more than 90% of users evaluated the application as easy to use, had a pleasant interface, had the intention of using it, would recommend it to others, and were satisfied with the overall application. The mean analysis showed a score of 4.6, which indicates that most of the participants were satisfied with the application. The interview results suggested the application to add brand recommendations and customize features for children’s shoes. These open opportunities for future work to improve the acceptance and quality of the application. Users who wish to buy shoes online could benefit from the application by finding the right fit based on foot size, shoe brand and type easily using their smartphone.

The purpose of this study is to investigate the effects of hole/holes on stress concentrations in a plate using a current industry standard software - Finite Element Analysis (FEA). Plate with hole/holes is a common engineering application such as in automobile, marine, aerospace and mechanical structures. Hole/Holes can be seen in many thin-walled mechanical and automobile structures and components. For example, hole/holes are found in residential/commercial buildings’ steel structural studs to allow plumbing installation, web or flange of steel box girders in bridges is furnished with holes to ease inspection works, electrical and heating conduits in the walls or ceilings and ribs attached to the main spar of an aeroplane’s wing are frequently come with holes. These hole/holes are one type of discontinuities within the structure (e.g. thin plate) that leads to changes in elastic stiffness and may tend to failures. Proper knowledge of stresses, strains, deflection and stress concentration (SC) are required to design any structures. In the geometry of the plate, under different loading, stress concentration rises from any abrupt change. And due to this, throughout the cross-section, the uniform stress distribution does not occur. At a point of stress concentration, as a results failures like fatigue cracking and plastic deformation commonly occur. Hence, it is very important in any engineering structural design to know about the stress concentration on plates with holes. In the present study stress concentration in a plate with a circular central hole and offset hole subjected to uniaxial loading (axial tension) is calculated using Finite Element of Analysis (FEA). Equations of SCF given by Peterson are dependent on three parameters namely, hole radius (a), distance from the bottom edge to the centre of hole (c) and distance from top edge to centre of hole (e). By varying either ‘c’ or ‘e’ or the ratio of ‘e/c’, an effort is made to study stress concentration factors for the determination of the edge effect by varying the hole to edge distance. The results show that von Mises stresses increased with increasing ‘e/c’ or ‘a/c’, which in turn increases SCF and finally leads to failure.

Although a considerable amount of research has been focused on how building information modeling (BIM) helps improve sustainable construction, BIM(6D) model validation and efficient data analysis methods are still lacking. This study aims to provide the more effective research method and analytical method. The Greenjiansville Sunshine analysis software Sun2020 and daylight analysis software Dali2020 were used for 6D modeling and simulation and real simulation of a building outside the daylight range and time. The daylight coefficients, outdoor visual field observation rate, and daylight quality were calculated for the rooms inside the building. The results show that single the daylight statistics and analysis color map can not accurately analyze whether the actual daylighting meets the demand, but combined with Power BI comprehensive analysis can get fast and accurate results. This paper provides important guidance for building researchers and practitioners to better align BIM development with green building development in the future.

Published: March 2023

Este trabajo se propuso estudiar el nivel de conocimientos sobre el Trastorno del Espectro del Autismo (TEA) que poseen 51 maestros. Se empleó el Autism Knowledge Questionnarie (AKQ) como instrumento para evaluar el conocimiento sobre el TEA. Se obtuvo que un 5.9 %, 47.1 % y 47.1 % de los participantes presentaron, respectivamente, un nivel de conocimiento débil, aceptable y bueno. Las carencias de conocimiento se asociaron con la comorbilidad, las características del TEA y los efectos de la medicación. Los resultados de los ANOVAS evidenciaron que las puntuaciones medias en el AKQ no difirieron significativamente en función del género, la formación universitaria, los años de experiencia docente y el tipo de centro. Respecto al perfil profesional actual, los maestros de Educación Especial o Audición y Lenguaje obtuvieron medias significativamente más elevadas que los maestros de Educación Primaria (d = 6.41). Del mismo modo, aquellos profesionales que habían tenido contacto con personas con TEA presentaban un nivel de conocimiento considerablemente más alto que los que no (d = 7.62). En conclusión, es necesaria una reconceptualización de la formación docente donde prime el contacto con el alumnado con TEA para enriquecer su conocimiento y, así, llevar a cabo una Educación Inclusiva.

A simple routing algorithm to improve vehicle safety on a road network has been proposed. If the road network is represented by a graph with edges and nodes, it is sufficient to mark edges with highest incidence (top 800) of severe Traffic Accidents (TA) by adding to the attribute of the edge some penalty and the routing algorithm (Dijkstra or Bellman-Ford) will try to avoid these edges automatically. To estimate safety gain, a Relative Risk Ratio RRR = (TAs along route which avoids TA hotspots/TAs along original route) introduced in [1] was used. Computer simulation was performed for Moscow, Russian Federation. It is shown that for the same start and end points of the route, an average RRR gets smaller by 9...31 % depending on original route length. It is also shown that the cost for improving vehicle safety is an increase in the route length (by 6...11 %) and an increase in the number of nodes in the route (by 6...28 %).

The article presents an approach to modelling traffic flows based on the intelligent analysis of unmanned ground vehicles (UGVs) dynamics within of which a novel decision-making system on maneuvering for agent-UGVs is designed. The proposed system uses clustering methods for an estimation of a traffic congestion density on alternative routes of the digital road network (DRN) to detour problem areas and minimisе risks of traffic accidents appearing. For the first time, the spatial dynamics of interacting UGVs is modelled with complex schemes for constructing the DRNs, including multiple intersecting ring, straight and diagonal sections that form various alternative routes for road users. The de­veloped model is implemented with the supercomputer agent-based modelling framework FLAME GPU. An algorithm for the behaviour of UGVs during the formation of traffic congestions has been developed, in particular, it provides an effective splitting of traffic flows by increasing the probability of choosing less pressed alternative routes for UGVs. As a result of numerical experiments, the following important regularity was obtained: an increase in the share of UGVs in the DRN using intelligent maneuvering based on cluster analysis of traffic flows with a controlled radius of an agent personal space provides a decrease in the total density of traffic congestion and contributes to a decrease in accidents.

It is shown that in the course of the experiments, the wearable oculointerface had a lower average recognition error than the remote oculography interface, however, due to the design features, it is less convenient for the end user.
Folk prayer as a part of stereotypic behavior in Persian linguistic culture
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, SOPILNIAK S.
Published: March 2023

The speech genre of prayer as a component of stereotypical behavior of Persian linguistic culture bearers on the basis of Persian folk omens and superstitions is considered. The historiography of stereotypes, in particular communicative-behavioral stereotypes in modern linguistics, is briefly presented. The concept of speech genre is characterized. According to M. Bakhtin's definition, any human communication is based on certain speech genres, which are often stereotyped. Since the speech genre is the most important category of discourse, the classification of discourses by I. S. Shevchenko and O. I. Morozova is represented. Researchers distinguish the following subtypes of discourse within the socio-situational parameter: political, administrative, legal, military, religious, medical, business, advertising, pedagogical, sports, scientific, electronic (Internet discourse), and media varieties. Ritual type of discourse, which is relevant within the scope of the study, was also added to this typology. The speech genre of Persian folk prayer, verbalized by the words "do'ā" / "verd", is described, since it is folk, not traditional religious prayer in the context of Persian folk omens and superstitions to be a component of stereotypic behavior of Iranians and to perform primarily psychological, phatic and suggestive functions. It is determined that folk prayer in Persian linguistic culture functions not only as an act of saying a certain text to the God or the saints, but also as a talisman or amulet. Traditionally, such talismans are made in the form of texts or sayings from the Qur'an, written on a piece of paper, leather, cloth or metal. People attach these to clothing or simply carry with themselves. The central element of Persian folk prayer is a request. It has been found that there is a number of stereotypes in Persian linguo-mentality associated with images of prayer, which in turn affect the behavior of native speakers in different life circumstances. Analysis of Persian omens and superstitions on the basis of modern fiction has indicated that prayer is associated primarily with the need for protection, satisfaction of needs and hope in the minds of Iranians. It is noted that the appeal of native speakers of the Persian language and culture to folk prayer in certain situations is accompanied by a number of stereotypic ritual and semiotic actions, which demonstrates a combination of religious and magical aspects in their minds. It is stated that the specificity of the Persian speech genre of prayer is in the fact it simultaneously belongs to two types of discourse – religious and ritual.
Overview of the formation and development of Chinese language literature in Thailand
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, VECHORYNSKA T.
Published: March 2023

The Thai-Chinese literature represents more than century-old experience of Chinese immigrants in Thailand recorded in literary works. It is the embodiment of life's vocations, dreams and thoughts of Chinese immigrants, as well as an important symbol of the struggle for Chinese cultural identity. In modern Thailand, the native language of ethnic Chinese is Thai. For the Thai population, Chinese is the second foreign language to learn while English is the first. In the realities of the lack of permanent cultural ties and a stable language environment, Chinese-language writings in Thailand are unique and special in their subject matter and issues. Given the fact that studies of Overseas Chinese literature of the twentieth and twenty-first centuries in the world are mostly focused on literary works in North America, the study of Chinese-language literature in Southeast Asia, in particular Thai-Chinese literature, receives less attention. The oeuvre and achievements of this literature have not yet received a proper deep and detailed scientific understanding and assessment of the aesthetic features and uniqueness of this literary phenomenon. And this is the reason why the study of modern Thai-Chinese literature is of great importance. This paper is of an overview character and is devoted to the formation and development of Thai Chinese-language literature from the early twentieth century to the present. Particular attention has been paid to the challenges and obstacles that have accompanied the development of Chinese-language writing in Thailand throughout history. Readers are also invited to get acquainted with the Ukrainian translation of the short story by the Thai writer of Chinese origin Nian Lamei "Girl with a floral garland".

According to the results of the online academic conference "Waka poetry around the world: Viewing reception and transformation of Japanese culture through multilingual translation", an analysis of the Ukrainian translation of the 469th waka poem from the poetic anthology "Kokin Wakashū" (the Collection of Japanese Poetry Ancient and Modern) by I. P. Bondarenko was carried out. It is this translation that is the subject of the presented study. The goal, which was to reveal the peculiarities of the Ukrainian version of the mentioned poem, was achieved due to its comparison with Chinese, English, French, German, Hungarian, Italian, and Spanish translations. It was found that the Ukrainian translation of the waka poem No. 469 from the anthology "Kokin Wakashū" is characterized by common features that are typical for a number of translations into European languages. In particular, the syllabic structure of the original (a waka poem is composed of 5-7-5-7-7 syllables) has not been preserved in the Ukrainian translation, as well as in the other translations, and these translations themselves are written in five lines. Such common features also include lexical-semantic transformations caused by the difficulties of translating Japanese realia into European languages. For example, such nominations from the original work as "hototogisu" and "ayame" in many multilingual translation versions, including the studied Ukrainian one, are translated with the help of the words "cuckoo" and "iris", respectively, instead of their exact analogues – "lesser cuckoo" and "iris sanguinea". At the same time, there are foreign language versions with observance of the original syllabic verse and an accurate translation of the mentioned realia. Along with the common features, some features that make the translation of the 469th waka verse into Ukrainian unique were also revealed. Among those the translation of the original "satsuki" (the fifth month according to the old calendar and approximately June according to the modern one) as the season of the growth of herbs through the Ukrainian equivalent to "May" (the fifth month according to the modern calendar) literally meaning the "month of herbs", as well as the combination of the first and the second part of the poem through an emotional connection can be named.
MULTIPLANNING OF THE METHOD OF THE INTERLINGUAL COMPARATIVE ANALYSIS OF THE RELATED / UNRELATED LANGUAGES
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Korbozerova Nina
Published: March 2023

In the era of globalization and the expansion of language contacts, the interest of linguists in typological studies of related and unrelated languages is growing, which allows to reveal and clarify the national picture of the world in any language. In the field of comparative research, linguistics of the 21st century is characterized by the differentiation of the directions. When conducting a comparative analysis of languages, scientists use the following basic methods that have become traditional: comparative-historical, comparative, typological, contrastive. Recently, the latest research methods have been added to them, thanks to which the comparison of languages turns into a deeper, brighter and multifaceted one. First of all, it concerns areal typology and taxonomic typology. Comparative-historical linguistics studies genetically related languages in a diachronic aspect. In the 19th century, this direction is associated with the names of F. Bopp, J. Grimm, R. Raskov, A. Meillet, and F. Dietz. The goal of research in comparative-historical linguistics is the reconstruction of ancient platforms common to all related languages. In this direction, the indisputable achievement of the Romanistic school of F. Dietz is the discovery of Romano-Latin archetypes. The kinship of the languages of the world is established according to the main feature of their common origin, which makes it possible to classify languages into families/subfamilies, branches, groups and directly into languages. At the same time, accidental coincidences and lexical borrowings are not taken into account. A language family is a basic language structure, according to which closely related and distantly related languages are defined. Languages that make up one language family have common features, are the result of one language that historically preceded them, and belong to the group of related languages. This gives rise to the concept of the genealogical tree of languages and the concept of linguistic divergence. Related languages are considered variants of one continuous language tradition, different in time and space. An example is the Indo-European family of languages that share a common language, or proto-language (Indo-European). Within related languages, subgroups are distinguished, which include languageы that are closest in origin (for example, Spanish and Italian languages). In turn, languages that belong to different groups of the same family are distantly related (eg, Ukrainian and Spanish). The group of unrelated languages consists of languages that originate from different protolanguages and belong to different language families. Linguistic, or comparative, typology arose within the framework of comparative-typological linguistics and is associated with the names of A. Schlegel, A. Schleicher, V. Humboldt. Thanks to the research of representatives of the school of linguistic typology, the question of the type of language was first raised and resolved.

In recent decades, the prospect of using a biomarker strategy for early personalized diagnosis of cardiovascular pathologies has been actively explored. The use of new markers appears promising, and the search for an “ideal” marker is actively ongoing, which will make it possible to understand various mechanisms of cardiovascular diseases. In recent years, scientists have actively focused on studying the role of neuregulin-1 as a laboratory biological marker in cardiac pathology. Neuregulins belong to a superfamily of epidermal growth factors that are synthesized by the vascular endothelium in response to ischemia, adrenergic stimulation, and oxidative stress.
Several studies have shown the potentially important diagnostic and prognostic value of assessing neuregulin-1 as a biological marker. Thus, further scientific and clinical studies will demonstrate the possibility of using this marker as an additional laboratory tool for diagnosing, risk stratifying, and predicting cardiovascular events in patients with cardiovascular pathology. The therapeutic effect of recombinant neuregulin-1 on reducing morbidity and mortality in patients with cardiac disorders require more detailed assessments.

Authors: Semiletova Vera A. , Gubina Olga I. , Kozlova Angelina D. , Popov Maxim V.
Published: March 2023

BACKGROUND: Aromatherapy is one of the simplest and most effective methods of influencing the functional state of a person. It is applicable both for therapeutic purposes in adults and children, and for restoring the psychoemotional and physical state of a person, which requires a detailed study of the psychophysiological mechanisms of the impact of individual aroma oils on the patient. Moreover, a wide choice of oils allows you to determine the necessary spectrum of action of a particular smell, and the activation of the olfactory sensory system causes a number of physiological reactions and affects the body in a complex way.
AIM: To study the human heart rate variability under the influence of aromatherapy with sweet orange and pine oils.
MATERIALS AND METHODS: The aromatherapy session was conducted for 25 minutes. Before and after the aroma session, the simple visual-motor reaction (sVMR) of the subjects was determined and the heart rate was recorded on the VNS-Micro hardware-software complex (Neurosoft, Russia) in lead II, at rest, sitting, for 5 minutes. Statistical processing of the obtained data was carried out using Excel and IBM SSPS Statistics 26 programs.
RESULTS: Maximal RR intervals after rest were significantly higher than at rest before rest. The net regulatory effect (SDNN) increased significantly. The activity of the autonomous regulation circuit (RMSSD), the total wave power (TP), the power of the low-frequency component of the spectrum (LF), the power of the high-frequency component of the spectrum (HF) increased significantly. The centralization index (IC) increased after the rest.
Under the influence of the smell of pine, changes in heart rate variability and spectral power are insignificant. Significant changes in the power of the HF component of the spectrum were observed under the influence of the smell of orange it significantly decreased. The centralization index (IC) has increased.
After the aroma sessions with pine and orange oil, the time of the subjects' MTMR and their error increased, after the aroma session with pine oil, the error increased to a greater extent. Aromatherapy with sweet orange and pine oils eliminated the significant changes in the parameters of heart rate variability of the subjects, which were observed after a 25-minute rest in the control group.
CONCLUSION: After rest, the activity of the sympathetic nervous system decreased, the activity of the autonomous regulation circuit increased, the influence of the vagus and the influence of subcortical and cortical centers of regulation increased. Aroma session with oils of pine or sweet orange reduces the effectiveness of the sVMR of the subjects, while a 25-minute inhalation of pine aroma oil reduces the effectiveness of the sVMR to a greater extent.

Este artículo es producto de la investigación que se origina ante la necesidad de crear herramientas para fortalecer la participación democrática; que incide directamente en la falta de control del ejercicio del poder por parte de la ciudadanía, así como en la vulneración de Derechos; quizá por la falta de conocimiento ciudadano sobre los Derechos Constitucionales. Las consecuencias de dicha debilidad se asocian con desigualdad social, corrupción y violencia. Como propuesta emerge el alfabetismo jurídico, que desde su labor pedagógica y sentido práctico fortaleció la participación democrática y el control social. La investigación presenta el estudio, los hallazgos y los resultados. La metodología fue cualitativa desde el paradigma de la investigación acción participativa, con etapas holísticas de las pesquisas analíticas, desde la observación, sistematización y análisis; en varias localidades de Bogotá, con una muestra poblacional de 50 personas líderes y lideresas de las comunidades, previamente seleccionadas. De la literatura se incorporaron elementos pedagógicos mediante un diálogo de saberes. El trabajo coincidió con el aislamiento preventivo en pandemia del COVID-19, lo que exigió un escenario virtual de intervención y participación con la comunidad. Por último, uno de los impactos de la experiencia fue la exaltación de la necesidad de un compromiso institucional con la educación de la ciudadanía en aspectos constitucionales y en Derechos Humanos, donde la comunidad se comprometió a replicar los conocimientos, para incidir eficazmente en la transformación hacia una sociedad que conoce y practica sus Derechos.

Authors: Лурье А.Ж.
Published: March 2023

В качестве главного результата школьного образования выделяется готовность учащегося к самообразованию, самоконтролю и самоуправлению. Приводятся результаты исследований, доказывающие, что ключевым фактором, вызывающим стресс, в образовательном процессе являются оценки и сравнение результатов обучающихся между собой. Цель проводимой нами работы – создание нового бесстрессового способа оценивания достижений учащихся – трехмерной рейтинговой системы, ориентированной на развитие самоконтроля и самоуправления. Делается вывод об эффективности участия учащихся в оценивании, предоставления им права выбора уровня обучения, последовательного суммирования оценок ученика по каждому модулю предметов, его достижений в исследовательской деятельности, а также во внеучебной творческой деятельности, включая самоуправление.

The main result of school education is the student’s readiness for self-education, self-control and self-government. The results of studies are presented proving that the key factor causing stress in the educational process is the assessment and comparison of the results of students with each other. The purpose of our work is to create a new stress-free way to assess students’ achievements – a three-dimensional rating system focused on the development of self-control and self-government. The conclusion is made about the eff ectiveness of students’ participation in assessment, giving them the right to choose the level of education, sequentially summing up the student’s grades for each module of subjects, his achievements in research activities, as well as in extracurricular creative activities, including self-government.

Published: March 2023

In type 2 diabetes mellitus, lipid profile is often found in the form of high-density lipoprotein (HDL) decrease. TNFa and IL-6 are proinflammatory cytokines that are elevated in the blood in many patients with diabetes mellitus. Turmeric is one of the natural ingredients that has anti-cholesterol and anti-inflammatory effects through the work of its active substance, curcumin. This study aimed to evaluate the effect of turmeric extract combined with metformin on HDL, TNFa, and IL-6 levels in diabetic rats. Twenty-four Wistar rats were injected intraperitoneally with streptozotocin and niacinamide. The diabetic rats then were divided into four groups; control group, metformin group, turmeric group, and combination group. The dose of metformin and turmeric which were given, respectively, 45mg/KgBW/day and 200 mg/KgBW/day. While the combo group was given half dose of each. Blood serum was taken to examine the HDL, IL-6, and TNFa levels. The levels of HDL, IL-6, TNFa on diabetic rats that received the combination of metformin and turmeric extract (p0.05) were the best among of all the groups. This means that the combination of metformin and turmeric is better in increasing HDL, reducing IL-6, and TNFa levels better than metformin or turmeric extract alone.

Authors: PN Savitha , Potluri Nikitha
Published: March 2023

Comparison of two surface sealants on surface roughness and color stability of a commercially available denture base material.

Metallic discs were invested in a denture flask using dental stone to prepare a mold space. The denture base polymer and monomer were mixed in a ratio of 3:1 by volume and processed to form disc disc-shaped specimen. All the samples were finished, polished and checked for surface roughness. Sealants were applied on denture base material and cured using light-curing unit. All the 120 samples were divided into Group I(n=60) – Lucitone 199 and Optiglaze, and Group II(n=60) – Lucitone 199 and Easy Glaze. All the specimens were further subdivided into three groups based on the solution they were immersed i.e, coffee (n=20), tea (n=20), and distilled water (n=20). The specimens were checked for surface roughness and color stability for one week, one month, two months, three months, and four months. Samples were checked for surface roughness using optical profilometer and colour change using a spectrophotometer.

The surface roughness of all the samples was within the normal range and tea-stained higher compared to coffee samples for color stability.

The study concluded that Optiglaze is a better sealant compared to Easy Glaze with better properties like less surface roughness and good color stability of commercially available denture base materials. All groups had surface roughness less than the plaque accumulation threshold (0.20 µm). Beverages affected color stability of commercially available denture base materials after the application of two different surface sealants.
