This study investigates the use of Corrosion Health Monitoring (CHM) systems to detect and manage corrosion in aviation environments, with a specific focus on enclosed areas within aircraft structures. Corrosion poses significant risks to airport facilities and aircraft, and CHM systems offer real-time monitoring and data-driven approaches for proactive corrosion management. Through case studies conducted at two different test sites, the effectiveness of deploying advanced sensors was demonstrated in identifying corrosion-prone areas, optimizing maintenance schedules, and enhancing safety and structural integrity. The study highlights the variability in corrosion rates between openair and enclosed conditions, emphasizing the need for tailored prevention strategies. It also discusses the challenges of integrating CHM systems into existing maintenance practices and airport infrastructure, addressing issues such as sensor placement, data management, and regulatory compliance, and outlines future directions for R&D in this critical area. By incorporating CHM systems, the aviation industry can transition from reactive to predictive maintenance, improving the reliability and lifespan of assets while reducing costs.

Authors: NWANKWO Cosmas Anayochukwu , KANYANGALE MacDonald Isaac
Published: November 2024

The application of entrepreneurial marketing (EM) strategies to the sustainability of profit and non-profit making ventures has drawn critics from practitioners and academic domains. Many have argued that EM dimensions are designed for profit marking ventures and not for profit venture. This informed the need to examine the effect of EM on the survival of social enterprises (SEs) in Nigeria. The study selected SEs staff in Anambra State, Nigeria using a quantitative research approach. Data were collected from 387 SE staff using a structured questionnaire. Hypotheses were tested using International Business Machine Statistical Package for the Social Sciences (IBM-SPSS) and International Business Machine -Statistical Package for the Social Sciences - Analysis of Moment Structures (IBM-SPSS-AMOS) version 27 that runs exploratory and confirmatory factor analysis and structural equation modelling (SEM). The findings revealed that all the EM dimensions, except market sensing, have significant and positive effect on the survival of SEs in Nigeria. Therefore, the study concluded that EM has significant effect on the survival of SEs in Anambra State, Nigeria. The study recommended that practitioners should adopt and implement EM dimensions as the basic enablers that would sustain the existence of SEs in both Nigeria and beyond.
Youth’s Awareness about Skin Cancer, with Particular Emphasis on Melanoma
Authors: Zaborska Monika , Marek Anita , Ogonowska Weronika , Niedbał Zuzanna , Michalik-Marcinkowska Urszula
Published: November 2024

Background:
Cancer is a health problem both in Poland and around the world due to its incidence and potential mortality. Melanoma is a malignant skin tumor that originates from melanocytes. It is the most important risk associated with UV radiation. An important topic is the promotion of knowledge of it among young people from an early age to prevent skin lesions. Skin disease prevention should be discussed at subsequent stages of school education. Children and adolescents should be aware of the negative effects of UV radiation.

Objectives:
The study aimed to assess the level of knowledge and use of protection by primary and secondary school students regarding the occurrence and prevention of skin cancer, with particular emphasis on melanoma.

Material and methods:
As many as 224 young people took part in the study. An original questionnaire was used, consisting of sociodemographic questions and questions checking young people’s knowledge about skin cancer risk factors and skin disease prevention. The survey was voluntary and anonymous. To check the statistical significance of the obtained results, the significance level of p < 0.05 was adopted.

Results:
Skin problems occurred in 38.84% (N = 87) of respondents. Most of the respondents (80.36%, N = 180) do not use solariums and are aware that solariums are the main factor causing melanoma (81.70%, N = 183). As many as 78.57% (N = 176) of respondents claim that skin disease prevention has never been discussed at school and most young people (60.27%, N = 135) do not know about dermatoscopic examination. Most students (70.54%, N = 158) expressed their desire to expand their knowledge about skin diseases and their prevention.

Conclusions:
Due to the limited knowledge of children and adolescents about skin cancers, including melanoma, as well as the common disregard among this group of preventive measures related to the broadly understood prevention of their development, further theoretical education and promotion of healthy behaviors that reduce the risk of the disease are necessary.
DETERMINANTS IN MODELLING EARLY SCHOOL DROPOUT
Authors: Cibu Bianca-Raluca , Delcea Camelia , Domenteanu Adrian
Published: November 2024

Recognizing the importance of continuity in education, it was deemed necessary to carry out a study whose main objective is to identify the factors that lead to the intention to drop out in order to formulate effective strategies to combat this phenomenon. Early school dropout has negative consequences both for individual development and for social and economic progress. Therefore, this paper aims to contribute to the understanding and prevention of this phenomenon through a rigorous analysis of its determinants. In this context, eight relevant dependent variables have been identified in the literature that are believed to play a significant role in the intention to drop out of school. These variables include factors such as school absenteeism, alcohol or substance abuse, attitude, awareness, family, family supervision, school environment and school rules. The analysis used in the study examines these significant variables through structural equation modeling (SEM). SmartPLS software was used to conduct this analysis, which allows the use of Partial Least Squares SEM (PLS-SEM) and Bootstrapping modeling techniques. The data used for this research was collected using a well-structured questionnaire consisting of 28 questions aimed at capturing students' perceptions and experiences of school and the factors that might contribute to their intention to drop out of school. A total of 669 respondents completed the questionnaire, providing a solid database for analysis.
ARE THERE 'HYGIENE-MOTIVATION' FACTORS IN THE CHOICE OF INDIA AS A TOURIST DESTINATION? A STRUCTURAL EQUATION MODELING APPROACH
Authors: Diaconescu Vlad
Published: November 2024

This study examines the role of motivational factors in the selection of India as a travel destination, using Herzberg’s two-factor theory of motivation (Hygiene-Motivation model) as a theoretical foundation. By examining how stereotypes about India influence tourists' decision making, this study categorises motivational factors into hygiene and motivation categories and examines their influence on destination choice. A survey conducted at the Romanian Tourism Fair in February 2019 with 729 participants forms the basis for this analysis. Structural equation modelling (SEM) was applied to assess the relationships between these factors. The study reveals two main types of factors that influence tourists: Hygiene factors (e.g. accessibility, comfort, food and overall quality of services) and motivational factors (e.g. cultural richness, scenic beauty and local traditions). The study shows that stereotypes about India play a crucial role in shaping tourists’ priorities — those who have negative stereotypes are more likely to focus on hygiene factors, such as ensuring that basic service expectations are met. In addition, while motivational factors still play an important role, elements such as natural beauty and cultural experiences take centre stage in the travel decision.
THE ROLE OF SPECIAL EVENTS IN TOURISM

Published: November 2024

Event tourism is a particular form of tourism which, in order to attract visitors, requires the holding of special events. It is considered a subcategory of general tourism and differs from it by its characteristics, having a component of uniqueness (exclusivity), a component of fixed duration (depending on the duration of the event), a component of geographical concentration (the specific location of the event), but also a permanent and temporary economic impact (large influx of visitors). In this paper, the impact of three special events is analysed, each event in a different location, more precisely we analysed a mountain location (Băile Tușnad, Harghita County), a seaside location (Costinești, Constanta County) and an urban metropolis (Cluj-Napoca), all in Romania, in parallel we analysed an event outside the country (music festival in Belgium). The presentation and analysis of the figures from these four different locations leads us to conclusions and comparative interpretations. The study ends with the presentation of the conclusions and some suggestions in this direction of tourism, in our opinion to paint a real picture of this phenomenon, a successful tourism that requires a concentrated effort of all the actors involved, more precisely, the decision makers, entrepreneurs and tourists. The impact of special events on a local community is captured by figures that answer the two research questions: "Is there a relationship between a special event and the number of tourists?"; "Does a special event perceived as an economic accelerator also have negative aspects?"
Fuegos Fautos

Published: November 2024

No hay nada más fugaz que un comentario periodístico. Los medios electrónicos han agravado esa circunstancia porque es inevitable referirse en ellos a la actualidad más inmediata y notoria, de la manera más corta y precisa posible. El impacto de esas palabras es inversamente proporcional a su permanencia.

Hay sin embargo todavía un espacio para los análisis más mesurados y profundos. Sin alejarse de los hechos del presente es bueno referirse a los temas eternos de la cultura, la historia, la economía y la política. Las notas de este libro, escritas en los últimos tres años en El País de Cali y en Las2orillas de Bogotá, que generosamente me han acogido, publicadas por el Programa Editorial de la Universidad del Valle, mi casa de tantos años, tienen la pretensión de esa permanencia, que en todo caso es muy corta. Las he organizado por temas y en orden cronológico, bajo un nombre evocador: fuegos fautos.

Esas pálidas y fugaces llamaradas que brotan en la medianoche de los pantanos, solo visibles para un afortunado, insistente o pérfido observador, pero con una energía no exenta de misterio.
Public control in Antarctica: towards a problem statement
Authors: Maksimov Aleksandr Alekseevich , SCHegolev Igor'  Borisovich , Savchenko Marina  Stanislavovna
Published: November 2024

This article is devoted to the analysis of modern problems related to the possibility and necessity of organizing and implementing public control in Antarctica. The territory of Antarctica currently does not belong to any of the states of the planet, however, a number of countries, represented by their representatives (including military personnel), carry out their activities on the territory of this continent, which creates or may pose a threat to the environmental security of this region of the world. The norms of international law have consolidated the institution of observers, who are sent by States that are parties to the Antarctic Treaty of 06/23/1961. However, the civil society of the countries participating in this Treaty, other international and interstate agreements on Antarctica, for example, the Commission for the Conservation of Antarctic Marine Living Resources, as well as the Convention on the Conservation of Antarctic Marine Living Resources, in fact, is excluded from monitoring the activities, acts and decisions of both these international organizations and public authorities national States authorized to explore Antarctica and participate in international relations in this area. In the course of scientific research, a number of scientific methods were used, including: formal-logical; comparative-legal; historical-legal; statistical; sociological; method of analyzing specific legal situations. In this regard, the authors of the article analyzed international legislation on Antarctica, the mechanism of its development, conservation of natural resources, demilitarization, etc. The paper substantiates the need for the organization and control of civil society over the activities, acts and decisions of international governmental organizations, as well as public authorities of national states authorized to develop Antarctica and participate in international relations in this field. The authors formalized and analyzed the main problems that hinder the implementation of this control in this area. The article develops and substantiates a system of measures to resolve these problems, including by making appropriate changes and additions to the norms of international law, as well as national legislation on public control.
Effective Solutions for Moving Objects in Acceleration Functions and Their Reflections Using Goen's Distance Formula
Authors: Goenawan Stephanus Ivan
Published: November 2024

Goen's distance formula effectively calculates the distance from acceleration, which has a pattern as a symmetric function of time changes. In Goen's distance formula, where the acceleration function against time has a symmetric pattern, it can be solved simply by performing a total integral and multiplying it by half of the total time. Symmetric acceleration functions can be constructed by combining certain functions with their reflections. In this study, the method of proving Goen's distance formula is carried out mathematically using single and double-level average integrals of symmetric functions. The advantage of Goen's distance formula compared to the conventional distance formula is that in finding the distance traveled by an object moving with a symmetric acceleration function, it will be more effective because it is sufficient to perform an integral once compared to having to do two integrals as done in the conventional method.

ТРАНСКРАНИАЛЬНАЯ МАГНИТОТЕРАПИЯ В ЛЕЧЕНИИ ПСИХИЧЕСКИХ ЗАБОЛЕВАНИЙ
Authors: О.Л. Кирюхин , Л.Б. Кирюхина , Е.О. Мартынова , О.М. Урясьев
Published: November 2024

Транскраниальная магнитная стимуляция (ТМС) относится к неинвазивным методам стимуляции мозга, обладающий уникальными возможностями как для исследования, так и для модуляции нейронных систем и связанных с ними когнитивных и поведенческих функций у пациентов с психическими расстройствами. В качестве инструмента обследования современная ТМС может использоваться в сочетании с электроэнцефалографией (ТМС-ЭЭГ) для прямого, объективного и неинвазивного выявления активности определенной области коры, включая процессы возбуждения, торможения, реактивности и волновую активность, независимо от сознательного препятствования пациента. Ключевая роль ТМС в оценке и модулировании нейронных дисфункций и связанных с ними клинических и когнитивных нарушений, у пациентов, страдающих психическими расстройствами, становится все более очевидной в последние годы, когда уровень современной аппаратуры достиг высокого технического уровня. Магнитотерапию с диагностической и лечебной целью стали применять при лечении шизофрении и расстройств настроения. Созданы протоколы магнитотерапии обсессивно-компульсивных расстройств, депрессий и посттравматического стрессового расстройства. Технически, воздействие магнитного поля как правило нацелено на определенные области коры головного мозга, модулируя нейронные цепи и улучшая симптомы и аномальное поведение у лиц с психопатологией. Эффективность каждого из методов подтверждена в рандомизированных исследованиях и имеет высокий уровень доказательности. Диагностические возможности ТМС позволяют регистрировать обратную связь в процессе терапии и разрабатывать более эффективные персонализированные вмешательства для лиц с психическими расстройствами.

Широкий диапазон применения установок УФ-обеззараживания в различных режимах предъявляет требования к системам УФ-обеззараживания в общем, и к УФ лампе, как к ключевому элементу всей системы, в частности. Производителям УФ-оборудования необходимо учитывать, что доза УФ-излучения должна быть достаточной для инактивации патогенных микроорганизмов с учетом условий обеззараживаемой среды, например, таких как температура и пропускание воды на длине волны 254 нм. Наш опыт эксплуатации установок собственного производства показывает, что при низких температурах обеззараживаемой воды порядка +2 ■■4°С, а также в случаях относительно высокой температуры обрабатываемой воды +30^+35°С (например, сточные воды, технологические оборотные воды пищевых производств и т.п) интенсивность излучения падает, а равно с этим и УФ-доза, на которую рассчитанная УФ-установка, исходя из паспортных данных на УФ-лампы. Нами предложен новый состав амальгамы для УФ лампы низкого давления и проведена серия экспериментов с существующими на сегодняшний день аналогами. В результате было выявлено уменьшение, по сравнению с существующими лампами, падения интенсивности в крайних диапазонах температур.
Ладовая формульность в песнях эвенков Якутии
Authors: Л.И. Кардашевская
Published: November 2024

Статья посвящена проблеме формульных напевов в регинальной традиции, а именно рассмотрению ладовых закономерностей в песнях эвенков Якутии. Материалом для исследования послужили песенные традиции эвенков трех локусов Якутии (Алданского, Олёкминского, Оленёкского районов (улусов)). В статье отмечаются преобладающие ладовые структуры, выявляются интервальные соотношения между ладовыми опорами в эвенкийских лирических песнях, колыбельных и обрядовых напевах. При сравнительном изучении напевов установлены особенности, характерные для определенных локальных групп: песни алданских, олёкминских эвенков основаны на ангемитонном тетрахорде в объеме чистой квинты с интервальной структурой 3–2–2; песни оленёкских эвенков основаны на дихордовых (в объеме секунды либо терции) либо трихордовых ладах в объеме терции с интервальной структурой 2–2; в напевах алданских и олёкминских эвенков отмечается ладоопорный комплекс из трех устоев, состоящих в малотерцовом и большетерцовом интервальном соотношении (реже двух устоев, находящихся в квинтовом соотношении).

This article is devoted to the problem of formulaic melodies in a regional tradition, in this case, to modal patterns in the songs of the Evenki of Yakutia. It examines Evenki song traditions of three areas of Yakutia (the Aldan, Olekminsky, and Oleneksky districts [ulusy]). The article notes the predominant harmonic structures and reveals the interval relationships among them in Evenk lyrical songs, lullabies and ritual melodies. A comparative study of the melodies reveals features characteristic of certain local groups: the songs of the Aldan and Olekminsky Evenki are based on an angemythonic tetrachord in the volume of pure quinta with the interval structure 3–2–2; the songs of the Olenek Evenki are based are on a dichord (in the volume of second or tertia) or on trichordal harmonies in the volume of tertia with the interval structure 2–2; in the melodies of the Aldan and Olekminsky Evenki, there is a harmonic complex of three abutments consisting of a small-thumb and a large-thumb interval ratio (less often, two abutments in a fifth ratio).
Специфические приемы интонирования в песенной традиции дэгэрэҥ у северных саха
Authors: В.Е. Дьяконова , Н.Н. Варламова
Published: November 2024

Северные саха — уроженцы арктических и субарктических улусов (районов) Республики Саха (Якутия). Их ближайшими соседями являются коренные малочисленные народы Севера эвены и эвенки. В статье речь идет о разновидностях напевов в стиле дэгэрэҥ со специфическими типами фонации, бытовавших в традиционной песенной культуре северных саха. К ним относятся напевы с гортанными хрипами хабарҕа ырыата, нёбное пение таҥалай ырыата, пение в нос мурун ырыата и гнусавое пение хоҥсуо ырыа. В отличие от напевов с подобными типами фонаций, бытовавших в Центральной Якутии, напевам северных саха присуща обрядовая функция. Для напевов в манере таҥалай ырыата, хабарҕа ырыата, хоҥсуо ырыа характерно наличие тембровых преамбул со специфическими призвуками на вдох и выдох. Отличительной чертой манеры пения в нос мурун ырыата является интонирование всего напева в назализованной (носовой) звукоподаче. Статья основана на полевых материалах авторов, записанных в 2014 и 2024 гг. в Абыйском и Верхоянском улусах Якутии, полевых материалах Ю. И. Шейкина и научной литературе. Впервые сделано обобщение сведений о разновидностях напевов в стиле дэгэрэҥ со специфическими типами фонации Центральной и Северной Якутии, проведен сравнительный анализ песен северных саха со специфической манерой исполнения по типу интонирования и жанровой специфике, приводятся нотировки ранее неизученных песен, уточняется термин мурун ырыата.

The Northern Sakha, whose nearest neighbors are the Evens and Evenki, indigenous small-population peoples of the North, are natives of the Arctic and Subarctic uluses (districts) of the Republic of Sakha (Yakutia). This article deals with the varieties of “degeren” style chants with specific types of phonation that exist in the traditional song culture of the Northern Sakha people. These include chants with guttural wheezes (khabargha yryata), palatal singing (tangalai yryata), nasal singing (murun yryata) and twangy singing (khongsuo yrya). Unlike chants with similar types of phonation in central Yakutia, the northern Sakha chants are characterized by a ceremonial function. Chants in the manner of tangalai yryata, khabarga yryata and khongsuo yrya have special timbre preambles with specific sounds of inhalation and exhalation. A distinctive feature of the manner of murun yryata is the intonation of the whole chant in a nasalized manner. The article is based on the authors’ field materials recorded in 2014 and 2024 in the Abyisky and Verkhoyanskiy uluses of Yakutia; field materials collected by Yu. I. Sheykin; and the existing secondary literature. It attempts to draw conclusions on the varieties of degeren-style songs with specific types of phonation that appear in central and northern Yakutia. Further, it juxtaposes an analysis of Northern Sakha songs with their manner of performance in terms of intonation type and genre specificity; notations of previously unstudied songs are given, and the term “murun yryata” is clarified.
Бурятская колыбельная неверной жены и ее сибирско-тюркские параллели
Authors: А.С. Дылгырова , О.В. Новикова
Published: November 2024

Статья посвящена бурятским колыбельным, которые являются частью шуточного нарратива о жене, предупреждающей любовника, что муж вернулся домой и посещать ее не следует. По экспедиционным и опубликованным материалам устанавливается ареал бытования этого нарратива у бурят. Нотированные примеры колыбельных неверной жены, записанные от девяти исполнителей и публикуемые впервые, свидетельствуют, с одной стороны, о включенности их в бурятскую колыбельную традицию, а с другой — об особенностях, отличающих именно этот вид укачиваний. Устанавливается, что основным маркером колыбельных неверной жены становится поэтический текст, сообщающий о том, что отец семейства дома и его охотничье снаряжение, конь и собака на своих местах. Показательно, что данный сюжет был зафиксирован также у тувинцев, тоджинцев и хакасов-сагайцев. Наряду с несомненными чертами общности, обнаруживаемыми между бурятским и тюркскими этническими вариантами сюжета, у каждого из рассматриваемых этносов текст шуточного нарратива приобрел специфические национальные черты, а самое главное — его поющаяся часть полностью вписывается в местные колыбельные традиции. Это, вероятно, свидетельствует о давности бытования данного нарратива, распространившегося в период интенсивных контактов тюркских и монгольских народов на территории Сибири.

This article is devoted to Buryat lullabies which belong to a comic narrative about a wife who warns her lover that her husband has returned home and that he should not come visit. It establishes the area in which these lullabies circulate, based on expeditionary and published materials. Examples of lullabies with musical notes about an unfaithful wife, recorded from nine performers are published here for the first time. They indicate their inclusion in the Buryat lullaby tradition, on the one hand, and on the other, display the features that distinguish this type of lullaby. The main marker of these lullabies are lyrics that report the location of the father of the family’s house and of the equipment for hunting, horse and dog, in and around the dwelling. It is significant that this plot was also recorded among Tuvans, Tod-Zhins and Khakass-Sagays. Along with the definite features in common among the Buryat and Turkic variants of the plot, the text of the comic narrative also exhibits specific national features in each of the ethnic groups under consideration; most importantly, the parts that are sung fully correspond to local lullaby traditions. This probably indicates that this narrative is ancient and spread during a period of close contact between Siberian Turkic and Mongol peoples.
Колыбельные песни айнов
Authors: Н.А. Мамчева
Published: November 2024

В статье рассматриваются колыбельные песни айнов — аборигенов Дальнего Востока. Работа написана на основе анализа отечественной, зарубежной научной литературы и авторских нотных расшифровок. В научный оборот вводятся новые факты о песенном фольклоре айнов. В центре внимания находятся закономерности, связанные с музыкой и текстами колыбельных песен, которые до сих пор не рассматривались в отечественном и зарубежном музыкознании. Айны относятся к народам «колыбельной цивилизации», их духовная культура имеет мифологическую основу. Специфика музыкальной культуры обусловлена ее тесной связью с особенностями мировосприятия народа. В текстах колыбельных песен используются магические мотивы, ощущается тесная связь с мифологическими представлениями этноса. Впервые в отечественном музыкознании детально исследуются характерные черты айнских колыбельных песен в области тембра, звуковысотности, лада, метроритма, композиции. Близкие контакты айнов с различными этносами обусловили взаимопроникновение их культур, что нашло непосредственное отражение в сходстве колыбельных песен айнов и нивхов, уйльта (ороков) — народов, с которыми происходили наиболее частые контакты.

This article examines the lullabies of the Ainu, an aboriginal people of the Far East. It is based on an analysis of the author’s musical transcriptions as well as domestic and foreign secondary literature and introduces new facts about the song folklore of the Ainu. Focus is on patterns associated with the music and lyrics of lullabies, which have not yet been considered in scholarship. The Ainu belong to the peoples of a “cradle civilization” whose spiritual culture is based in mythology. Their musical culture is closely connected with the peculiarities of their worldview. The texts of lullabies use magical motifs and have a close connection to Ainu mythological ideas. For the first time in Russian musicology, the characteristic features of Ainu lullabies in the field of timbre, pitch, mode, meter, rhythm, and composition are analyzed in detail. Close contacts of the Ainu with various ethnic groups, especially the Nivkhs and Uilta (Oroks), led to the interpenetration of their cultures, directly reflected in the similarity of their lullabies.

Glioblastoma is a major unmet clinical need characterized by striking inter- and intra-tumoral heterogeneity and a population of glioblastoma stem cells (GSCs), conferring aggressiveness and therapy resistance. GSCs communicate through a network of tumor–tumor connections (TTCs), including nanotubes and microtubes, promoting tumor progression. However, very little is known about the mechanisms underlying TTC formation and overall GSC morphology. As GSCs closely resemble neural progenitor cells during neurodevelopment, we hypothesized that GSCs’ morphological features affect tumor progression. We identified GSC morphology as a new layer of tumoral heterogeneity with important consequences on GSC proliferation. Strikingly, we showed that the neurodevelopmental morphoregulator ADD3 is sufficient and necessary for maintaining proper GSC morphology, TTC abundance, cell cycle progression, and chemoresistance, as well as required for cell survival. Remarkably, both the effects on cell morphology and proliferation depend on the stability of actin cytoskeleton. Hence, cell morphology and its regulators play a key role in tumor progression by mediating cell–cell communication. We thus propose that GSC morphological heterogeneity holds the potential to identify new therapeutic targets and diagnostic markers.
Event Analysis: Application in Social Forecasting
Authors: Korenkova T. V. , Artamonov A. A. , Ulizko M. S.
Published: November 2024

Monitoring the interrelationships between social events and phenomena and forecasting the dynamics of their changes are necessary in the conditions of instability of the modern world. There are many separate methods of analysis for social forecasting, however, for this research, the method of event analysis has been chosen, which is insufficiently considered in the scientific literature within the framework of this task, but has high potential. The purpose of the article is to adapt the event analysis methodology for its use as a social forecasting tool. The main data for the study was collected from the Russian information and news resource in the period 2020-2023. Based on the classical methodology of event analysis, the classifiers presented in this paper in the form of social spheres are defined in the research. As part of the analytical comparison stage, a graph analysis was carried out (graphs of relationships between categories were constructed, central nodes-categories were identified); time series analysis was performed (segmentation of time series by the PELT algorithm, clustering of time series by the k-means algorithm); key terms for press events were defined. The final product is an analytical dashboard with filters, statistics and interactive graphs. The analytical dashboard makes it possible to compare data in a static and dynamic state, to draw conclusions about the past and future states of objects of social forecasting. The main result of the research is the event analysis methodology developed by the author, which can be used for a comprehensive analysis of news streams, adapted to the necessary categories representing a certain entity or sphere, and applied in various social organizations or monitoring services.
Solutions to Teaching Reform Challenges of Elective Courses under the Background of New Liberal Arts: Taking International Trade in Services Course as an Example
Authors: Yu Huiqian
Published: November 2024

Variations in the allocation of university resources, teachers’ course selection preferences and teaching commitment levels, as well as students’ course preferences and assessment requirements, create subjective differences. These differences, compounded by the demands of the new liberal arts reform, place significant challenges and pressure on elective course instructors. To meet these demands, elective course teachers should enhance their teaching methods and explore new instructional models. The International Trade in Services course, for instance, has implemented six areas of curriculum reform, enriching the practice of elective course improvement.
The 9th Victor de Mello lecture: reflections and speculations
Authors: Hight David William
Published: November 2024

The paper reviews the published literature on some aspects of fabric and particle behaviour
in cohesionless soils. It uses insights from Discrete Element Modelling and Microcomputed
Tomography to speculate on reasons for the difference in behaviour observed between
moist tamped and sedimented sands at the same global void ratio and stress state. It is
suggested that inhomogeneities in the form of macrovoids in moist tamped samples trigger
localisation, collapse and the development of a local scale chain reaction. It questions
whether a similar sequence applies at the field scale and whether expansive partial drainage
influences the rate of propagation of the chain reaction. The paper offers reasons why the
use of critical state based on moist tamped samples to assess the stability of tailings, may
not be the best approach, and suggests that identifying instability lines for sedimented
samples at appropriate void ratios and principal stress directions, may be preferable. Critical
state reflects behaviour at large strains where initial and evolving inhomogeneities affect
identification of relevant void ratios; instability lines reflect behaviour at small strains
where inhomogeneities probably initiate collapse. The paper emphasises the importance
of spatial variations in local void ratios in loose material, the importance of anisotropy of
collapse potential and of load-controlled rather that strain-controlled shearing.

This innovative study addresses critical flood prediction needs in Bor County, South Sudan, utilizing machine learning to develop an intelligent forecasting model. The research integrates diverse analytical techniques, including land use analysis and rainfall calculations, with a decade of weather data to understand complex hydrological dynamics. This research employs machine learning classifiers such as Support Vector Machines, Decision Trees, and Neural Networks. Findings reveal promising results, with the Linear SVM classifier achieving 87.5% prediction accuracy for raw data and 100% accuracy for high-velocity flooding events. The Naive Bayes classifier matched this performance, while Artificial Neural Networks showed a slight advantage in runoff estimation. The study's novelty lies in its holistic approach, combining machine learning with advanced visualization tools and geographic information systems. This creates a dynamic, real-time forecasting system bridging sophisticated analysis and practical flood management strategies. Focusing on model interpretability and multi-scale forecasting enhances its value to policymakers and disaster management authorities. This research significantly advances the application of AI to flood prediction and disaster management in offering future studies on humanitarian challenges. By enhancing early warning capabilities, this system substantially reduces flood-related losses and transforms disaster preparedness in vulnerable regions worldwide, potentially saving lives and mitigating economic impacts. Doi: 10.28991/CEJ-2024-010-10-010 Full Text: PDF
Comparative Evaluation of Compressive Strength in Earth Blocks Enhanced with Natural Fibers

Published: November 2024

Portland cement is a key component in the production of concrete blocks; however, its production has an extensive carbon footprint that contributes towards climate change. In addition, the availability of aggregates is also often challenging and, as such, leads to production delays of concrete blocks, which ultimately causes delays in the completion of construction projects and constant price increases. The price increase of construction materials such as concrete blocks tends to affect the quality of houses being constructed in rural communities of the Pacific Island Countries (PICs), and this calls for the development of a low-cost alternative to ensure housing quality is not compromised. This project is being carried out to develop earth blocks as an environmentally friendly and sustainable substitute for concrete blocks that are widely used in the construction industry. Coir (derived from coconut fibers) and bamboo fibers were incorporated into these blocks as reinforcement materials, aiming to achieve the same level of strength required for use in construction. Additional adhesion of the earth block was provided by the usage of cement. The earth blocks were cured for 7, 14, and 28 days, after which they were subjected to various tests, including a compressive strength test, water absorption test followed by wet compressive strength test to compare its performance to ensure it has sufficient strength for it to be introduced into the market as a more eco-friendly, low-carbon-emission, and cost-effective construction material. The maximum compressive strength obtained during the test was 3.24 MPa. Following a comprehensive analysis of the data attained, the composition of 15% cement and 0.75% bamboo fiber emerges as the most ideal choice for creating marketable earth blocks. This composition strikes a balance between providing adequate strength and ensuring minimal reduction in overall strength when the blocks are exposed to wet conditions. Doi: 10.28991/CEJ-2024-010-10-013 Full Text: PDF
Influence of Integral Crystalline Waterproofing on Concrete Properties: Dosage Impact and Microstructural Analysis

Published: November 2024

The present research study aims to investigate the properties and performance of concrete containing an integral crystalline waterproofing (ICW) admixture, added at an optimal dosage to resist water without compromising structural integrity. To achieve this, an experimental program was conducted on specimens with ICW dosage variations ranging from 0 to 4.8 kg/m2. The impact on water absorption, pulse velocity, and microstructural characteristics was tested and analyzed using XRF and EDS techniques. The findings reveal that increasing the dosage decreases water absorption by approximately 43% at maximum dosage compared with the control. A 41% increase in pulse velocity indicates a denser concrete matrix. The principle of optimization is highlighted, as an overdose of ICW generates a non-structural crystalline gel at the bottom of the specimens. The optimum dosage range for ICW to improve water resistance without adverse effects on structural performance was determined to be 3.2 to 4.0 kg/m2. This research introduces a novel approach by evaluating the comprehensive performance of concrete in relation to ICW dosage, providing valuable insights into the practical application of ICW admixture to enhance concrete quality and durability. Doi: 10.28991/CEJ-2024-010-10-02 Full Text: PDF

Published: November 2024

Recognizing material waste as a significant global concern has influenced both the environment and the construction industry. The utilization of ceramic waste as a recycled material in construction projects has gained attention as an effective and sustainable approach to address environmental issues. This study examines the use of waste ceramic tile powder (WCTP) as a supplementary material in cement mortars to decrease the amount of cement required. WCTP was used in place of cement at percentages of 5%, 10%, and 20%. Four different mix designs were created and tested for the study, yielding a total of 48 specimens. Numerous investigations were carried out, including flow table evaluations, measures of dry density, assessments of compressive and flexural strengths, X-ray diffraction, and SEM-EDX testing. The objective of these investigations was to evaluate the specimens' mechanical and physical characteristics as a whole. The findings showed that using ceramic powder in place of some cement might enhance the properties of the mortar. The compressive and flexural strengths of the mortar were notably impacted by replacing 10% of the cement content with ceramic powder. The inclusion of ceramic powder significantly enhanced the mortar's microstructure interface, according to SEM-EDX studies. In the end, the utilization of ceramic powder was found to have a substantial positive impact on the environment by reducing waste. Doi: 10.28991/CEJ-2024-010-10-03 Full Text: PDF

Published: November 2024

Enhancing the interface shear strength is crucial in the capacity and design of several geotechnical structures when subjected to static loading. The efficiency of these structures can be enhanced by utilizing innovative designs that allow the mobilization of higher interface shear resistance with bio-inspired-engineered or structured (rough) surfaces when compared to conventional smooth or random rough surfaces of the same geometry (i.e., soil-foundation contact area). Bio-inspired-engineered surfaces used in this study are developed after surfaces with snakeskin-inspired and engineered rough designs that maximize the interface shear resistance in cohesionless and cohesive soils. The frictional behavior and resistance of the bio-inspired-engineered surfaces were experimentally evaluated utilizing a modified interface direct shear apparatus on three locally available sand specimens. Results from tests on smooth surfaces against three different sands mobilized almost the same resistance and soil contraction. The results indicate a behavior significantly influenced by the shape and arrangement of the surface features, accompanied by larger resistance and volume dilation. A parametric study on the characteristics of the structured elements on three sands revealed the isolated impact of elements arrangement, shape, and roughness on the maximum attainable interface strength. The surface element characteristic ratio is found to control the load-transfer mechanism between sand and bio-inspired-engineered structured surfaces. Doi: 10.28991/CEJ-2024-010-10-06 Full Text: PDF
