Pressure and thermal effects on Rayleigh fibre-optic strain measurement for soil–structure interaction
Authors: Eichhorn Geoffrey N. , Haigh Stuart K.
Published: June 2024

Optical strain sensing for structural health monitoring is sometimes deployed for field and laboratory study of civil structures. Rayleigh backscatter devices (ROFDR) are presented for use with geotechnical centrifuge research since they offer distributed sensing capabilities, and through this study are shown to have negligible interference from external pressure effects. A comparison between a single channel and multi-channel fibre optic rotary joint (FORJ) is presented in the context of transmitting optical strain data across a rotating interface. The orthogonal pressure effects of a free-floating fibre under isotropic pressure was <0.32 με/kPa and that the pressure effect on a fibre bonded to a metal surface was below the detection limit of the instrument, 1 με, for an applied pressure of 60 kPa. The ROFDR system showed highly repeatable measurement of a constant temperature reading in a water bath experiment. The system is stable to ±10 microstrain within 2-sigma for a >12 h constant temperature test. An example case of a pipeline buried in a slope experiencing a landslide is presented using fiber pairs to capture pipe stress / strain. Geotechnical centrifuge modelling in a 1 m drum was carried out using a multi-channel FORJ coupled with an ROFDR system.

Background: The estimation of the foetal age at death is challenging in many ways. Therefore, determining foetal maturity is frequently a more plausible solution to the dilemma of foetal viability. In an endeavor to create a maturity spectrum, this research aims at the pattern of major sites of ossification in the foetal hand and foot bones. Materials and Methods: The onset of main ossification centers in hand and foot bones was examined in 48 foetuses between 8 weeks and 9 months gestational age. Larger foetuses of 6 to 9 months of gestation (31.0 to 45.0 CMS CH lengths) were analyzed by roentgenography and by clearing procedure. Smaller foetuses of 20 to 205 mm CR length were cleared in potassium hydroxide, stained with Alizarin Red‑S, and examined for the appearance of ossification centers in the bones of the hand and foot. Results: In this investigation, the centers were first formed in the hand bones before the foot bones, on the right side before the left, and in females before males. Ossification spreads from the radial to the ulnar side of the hand and from the tibial to the fibular side of the foot. Conclusion: Relying on both size‑related and maturity‑related information will only boost the chance of getting close to genuine age when attempting to determine the age of foetal remains. Consequently, it is advised to use as much information as possible rather than taking a simple strategy, such as depending just on body size. KEYWORDS: Alizarin Red‑S, clearing, defatting, dehydration, KOH, ossification.

Design of Sulfur Resistant Cobalt Catalysts by Boron Promotion: Atomic Scale Insights
Authors: Kızılkaya Ali Can
Published: June 2024

The effect of boron promotion on atomic sulfur formation by hydrogen sulfide dissociation on Co(111), flat surfaces of cobalt nanoparticles, was investigated using Density Functional Theory calculations. The results show that on clean Co(111), hydrogen sulfide dissociation proceeds fast due to low activation barriers, yielding atomic sulfur on the cobalt surfaces. Boron promotion hinders the dissociation of hydrogen sulfide due to increased activation barriers. Furthermore, boron prevents the interaction of sulfur compounds with cobalt surface atoms, as these poisons bind on boron. The findings indicate that boron is an effective promoter that can be used to design sulfur resistant cobalt catalysts.

Determining the group of resource-oriented regions in the methodology of strategizing
Authors: Gerelishin R. I.
Published: June 2024

Regions with significant natural resource potential play an important role in ensuring the energy and economic security of the Russian Federation. To maximize the effect of using resource potential, scientifically based and methodologically correct regional strategies must be developed. For these purposes, it is necessary to develop a concept for a strategy for the regional development of resource regions, for which it is proposed to use the strategizing methodology of a foreign member of the Russian Academy of Sciences, Professor V.L. Kvint. One of the first tasks when developing a concept is to identify a group of resource-oriented regions. To achieve this goal, the author’s definition of resource-oriented regions has been prepared, and based on an analysis of foreign and domestic practices, an algorithm for calculating the level of resource orientation has been proposed, based on 3 indicators: the share of mining in the gross regional product, the share of mining in the structure of regional employment and the degree of industry concentration. It is shown that for calculations using the proposed algorithm in terms of industry concentration, not only the Herfindahl–Hirmschan index can be used, but also the Shannon index, which is logically opposite to it, adapted for economic research.

The calculations showed that the group of resource-oriented regions can include the Nenets, Yamalo–Nenets, Khanty–Mansiysk and Chukotka Autonomous Districts, the Republic of Sakha (Yakutia), as well as the Magadan and Sakhalin regions – these regions best meet the proposed definition of a resource-oriented region and can become the basis for developing the concept of a regional development strategy.
СООТНОШЕНИЕ ХРИСТИАНСТВА И КУЛЬТУРЫ В РЕЛИГИОЗНО-ФИЛОСОФСКИХ И ТЕОЛОГИЧЕСКИХ УЧЕНИЯХ XX СТОЛЕТИЯ
Authors: Положенкова Елена Юрьевна
Published: June 2024

Целью данной статьи является культурфилософская рефлексия соотношения христианства и культуры в теологических и религиозно-философских учениях XX столетия (на примере учений С. Н. Булгакова, В. В. Зеньковского, Ж. Маритена, П. Тиллиха).
Методология. Авторы статьи исходят из признания двух противоположных методологических подходов, сложившихся в философской и религиозной мысли, к проблеме соотношения христианства и культуры: антиномистического, в котором религия и культура противопоставляются друг другу, и холистического, в котором выявляются их внутренние взаимосвязи и черты подобия.
Результаты. Было раскрыто, что вышеназванные мыслители исходят из признания глубокой связи христианства и культуры, рассматривая христианскую религию в качестве основания, духовного средоточия подлинной культуры, задающего ей высокое трансцендентное смысложизненное содержание. Общей чертой всех рассмотренных культурфилософских учений является понимание современного состояния культуры как глубокого кризиса, трагического противостояния религиозной и секулярной культур. Было выявлено, что характер интерпретации связей христианства и культуры, а также этиология кризисного состояния последней в рассмотренных культурфилософских учениях в значительной степени обусловлены конфессиональной спецификой (православной, католической, протестантской) мировоззрения их авторов.
Перспективы исследования. Проведённое исследование и его результаты могут способствовать нахождению путей преодоления современного глобального цивилизационного и ценностного кризиса, а также разработке теоретической модели православной культуры.
ЦИФРОВОЙ ПЕРЕХОД ЮЖНОРОССИЙСКИХ РЕГИОНОВ К ИМПОРТОЗАМЕЩЕНИЮ: УЧЕТ АСИММЕТРИИ ОТРАСЛЕЙ ВЫСОКИХ ТЕХНОЛОГИЙ
Authors: Волков Виталий Александрович
Published: June 2024

Цель исследования — концептуальное и эмпирическое обоснование определяющей роли цифровой трансформации отраслей высоких технологий промышленного сектора регионов Юга России в формировании кратко- и долгосрочных сценариев их социально-экономического развития в рамках концептов информатизации, цифровизации и циркулярности с учетом высокой дифференциации этих территорий по экономическому, промышленному, инновационному и цифровому потенциалам.
Методологическая база исследования представляет собой конвергенцию ряда общесистемных теорий и концепций (системности, комплексности, сбалансированности, точек роста, инноватизации, цифровизации), а также импортозамещения, циркулярности, перехода к экономике предложения от экономики спроса, соответствия гипотезе взаимоувязанного и взаимосопряженного развития производственной и ресурсной экосистем региона. В процессе реализации задач и цели исследования использовался ресурсно-нормативный подход, сравнительный метод, динамический анализ.
Результаты исследования. В процессе исследования научно обосновано, что проводимая в настоящее время государственная политика структурного реформирования промышленности по модели импортозамещения с ключевой ролью высокотехнологичных отраслей определяется небывалым по масштабу запросом отечественной экономики в росте объемов производства высококонкурентной отечественной продукции, способной замещать существенно сократившийся импорт и повышать экспортный потенциал страны. Это согласуется с концепцией постепенного перехода от экономики спроса к экономике предложения. В статье обосновано, что «экономика предложения» (так современную российскую экономику характеризует Президент России В. В. Путин) детерминирует широкомасштабное развитие инновационного потенциала в отраслях высоких технологий обрабатывающих производств, а также не только освоение (внедрение), но и разработку прорывных (и подрывных) технологий, создание новых промышленных производств и отраслей, прежде всего в сферах, где имеется потенциал импортозамещения. В современной прикладной науке содержится обоснование того, что решение этих важнейших задач возможно исключительно на базе рационального распределения и использования эндогенных ресурсов (условие резильентности экономической системы) и в соответствии с гипотезой взаимоувязанного и взаимосопряженного развития производственной и ресурсной экосистем региона (гипотеза модели замкнутого цикла). В соответствии с этим автором предложена модель механизма последовательного цифрового перехода южнороссийских регионов к импортозамещению в индустриальной сфере с учетом существующей асимметрии отраслей высоких технологий.
Перспективы исследования заключаются в верификации разработанного механизма на примере регионов Юга России, а также научном обосновании возможности его тиражирования на другие регионы страны.

Published: June 2024

Background. Individuals with mild intellectual disability (ID) often encounter challenges in physical functioning, impacting their overall well-being and quality of life. Traditional exercise programs may not always be accessible or effective for this population due to various barriers. Adapted yoga programs have emerged as a promising alternative, offering tailored interventions to address the unique needs of individuals with ID.
Objectives. The study aimed to close this gap by examining the effect of a structured, modified yoga programme on factors related to physical functioning.
Materials and methods. A total of 40 students with mild ID, aged between 11 and 15 years, were selected from Special Schools in Coimbatore, Tamil Nadu. A quasi-experimental design was used in this study. The participants were divided into an experimental group undergoing an 8-week adapted yoga program and a control group maintaining regular activities. Physical function parameters were assessed using standardized tests measuring cardiorespiratory endurance, muscular strength and endurance, flexibility, body composition, and balance. The adapted yoga program, conducted by qualified instructors, comprised 8 weeks of sessions, 5 days a week, each lasting 45 to 60 minutes. Statistical analyses confirmed the normal distribution of data and employed paired sample t-tests to assess pre- and post-test differences, with SPSS version 20.0 used for analysis, setting the significance level at 0.05.
Results. After undergoing 8 weeks of adapted yoga training, the results showed a significant improvement in the upper body strength (P < 0.04), lower body strength (P < 0.001), core strength (P < 0.002), flexibility (P < 0.00), and static balance (P < 0.00). However, there was no significant difference in body fat and cardiorespiratory endurance between adapted yoga training.
Conclusions. This study highlights the potential of adapted yoga programs as an intervention for improving physical functioning in students with mild ID. These findings indicate that the implementation of adapted yoga can be a valuable and accessible intervention for enhancing physical functioning in this population.

Eceabat İlçesindeki Tarihi Cami Kitabeleri ve Hazirelerde Mevcut Osmanlı Mezar Taşlarına Dair Bazı Tespitler
Authors: Sabah İsmail
Published: June 2024

Gelibolu Yarımadası, Osmanlı Türklerinin burayı ele geçirmesiyle birlikte Türk nüfusun iskân edildiği ve günümüze kadar kesintisiz varlık gösterdiği bir coğrafyadır. Aynı zamanda Çanakkale Boğazı ile Ege Denizi arasında yer alması nedeniyle stratejik bir öneme sahiptir. Türklerin bölgeye yerleşmesi ile beraber Türk-İslam kültürüne ait yapılar inşa edilmeye başlamıştır. Cami, tekke, çeşme ve şadırvan yapıları bunlar arasındadır. Bu yapılardan bazıları ise varlığını korumuştur. Ancak günümüzde kimisi kullanılmakla beraber kimisi zamanla yıkılmış durumdadır.
Gelibolu Yarımadası’nın uç noktasını teşkil eden Eceabat İlçesi ve köyleri, Osmanlı dönemine ait mezar taşı ve kitabeler açısından zengin sayılabilecek durumdadır. Bu konuda Eceabat ilçesi ve köylerinde yapmış olduğumuz çalışmada Osmanlı dönemine ait 829 mezar taşı ve 67 kitabe tespit edilmiştir (Sabah, 2019: 11). Ancak 2019’dan günümüze kadar geçen süre zarfında Çanakkale Savaşları Gelibolu Tarihi Alan Başkanlığı’nın (ÇATAB) yürüttüğü faaliyetler neticesinde bu sayıya yenileri eklenmiştir. Fakat bunlar ilgili araştırmanın gerçekleştiği dönemde çeşitli sebeplerle (toprak altında bulunması gibi) tespit edilemediğinden eser içerisinde yer almamıştır. Mevcudiyeti sonradan tespit edilen bu eserlerden makale kapsamında kalanlara ise yeri geldikçe değinilmiştir.
Bu araştırmada Eceabat ilçe sınırlarında bulunan mevcut tarihi cami kitabeleri ve hazireleri incelenmiş olup söz konusu kitabe metinleri üzerine bazı tespit ve değerlendirmelerde bulunulmuştur. İnceleme kapsamına alınan camiler; Eceabat Merkez Camii, Kilitbahir Köyü Cahidî Sultan Cami ve Haziresi, Kilitbahir Köyü Tabip Hasan Camii, Kilitbahir Köyü Kırklar Camii, Bigalı Köyü Camii ve Çeşmeleri, Beşyol Köyü Camii ve Haziresi ile Yalova Köyü Camii ve Haziresidir.

Published: June 2024

El objetivo de este trabajo fue determinar las asociaciones entre la actividad física y comportamiento sedentario mediante variables sociales en estudiantes de cuatro instituciones educativas de Antioquia, Colombia. Se diseñó un estudio transversal con 1957 estudiantes entre 9 y 20 años. Los datos se recogieron mediante una encuesta virtual. Los resultados muestran que una mayor edad, un grado escolar superior y un nivel socioeconómico alto aumentan los comportamientos sedentarios; en contraste, el apoyo de los padres y el nivel socioeconómico alto aumentan la actividad física. También se determinó que los hombres son físicamente más activos que las mujeres. La actividad física se asocia con comportamiento sedentario, nivel socioeconómico, edad y sexo. El comportamiento sedentario se asocia con edad, apoyo de padres, nivel socioeconómico, actividad física y edad.

La COVID-19 es una enfermedad infecciosa multiorgánica que provoca un estado inflamatorio grave y altamente catabólico. Las personas adultas mayores en condición de fragilidad y que ya cuentan con enfermedades subyacentes son más susceptibles a presentarla y desarrollan síntomas graves, lo cual supondría limitaciones o discapacidades a largo plazo. En este artículo se describen los desafíos asociados a la rehabilitación de pacientes adultos mayores pos-COVID-19, por un lado, mediante el análisis de las secuelas físicas y psicológicas observadas a largo plazo, y por el otro, a través de la revisión de varios enfoques de rehabilitación propuestos por expertos. Se efectuó la búsqueda de información científica en el motor de búsqueda PubMed aplicando el criterio de los autores para la selección de contenido relevante. El principal desafío de la rehabilitación integral del adulto mayor pos-COVID-19 es la aplicación de un enfoque multidisciplinario que incluya la evaluación temprana del paciente a fin de prevenir problemas de salud derivados de las multicomorbilidades y de la situación de dependencia, fragilidad y vulnerabilidad propia de estos pacientes. Este enfoque debe incluir, además de la rehabilitación física y cardiopulmonar precoz, apoyo psicológico, de manera que se promueva la independencia del adulto mayor y mejore su calidad de vida en la sociedad.

Los desenlaces negativos en la residencia medicoquirúrgica, como el agotamiento, el estrés patológico, el abandono de la especialización, entre otros, se han afrontado desde la modificación del entorno laboral y educativo del estudiante con el fin de mejorar su desempeño durante la formación. No obstante, ante la baja efectividad de las estrategias utilizadas en educación médica y en aras de modificar la perspectiva del problema y ofrecer soluciones complementarias, se han incorporado estrategias basadas en la psicología positiva. De esta manera, los recursos personales del estudiante hacen parte de estas alternativas de creciente investigación, pues su optimización posibilita un nivel superior de interacción con su ambiente de aprendizaje, así como de control sobre su rendimiento académico y laboral. El ‘moldeamiento del trabajo’ se apoya en la teoría de demandas y recursos laborales. En este artículo se efectúa un análisis crítico y reflexivo acerca de los recursos personales y el papel favorable que estos cumplen en la regulación del trabajo, el aprendizaje y el bienestar del residente como parte de una propuesta hacia una nueva mirada al problema del desempeño laboral durante el proceso de formación académica de posgrado.
Degradation of industrial dyes with white rot fungi
Authors: Quintero Juan , Cardona Mariana , Osorio Juliana
Published: June 2024

White rot fungi have shown a great potential for degrading recalcitrant chemicals compounds as PAHs, explosives, pesticides, dyes, etc. This capacity is due mainly to an extracellular enzymatic complex that they use naturally in lignin degradation of wood. This work evaluated seven strains in function of its decoloration capacity of Orange II dye and industrail dyes Cibacrón® red, Erionyl® red, Terasil® blue y Erionyl® turquoise in semisolid and liquid mediums. Phanerochaete chrysosporium and Phanerochaete sordida showed high decoloration capacity, with a 98% for Orange II and between 82-86% for industrial dyes in liquid medium. In semisolid medium all dyes were totally eliminated. The growh fungi in each degrading tretatment of Orange II showed a diauxic performance, in the first step of fungi growth , they showed partial adsorption of orange II in biomass, posterior liberation in stationary step and finally total degradation in medium.
Study and characterization of bricks from a historical bridge in Buga (Valle del Cauca)
Authors: Galindo Jorge , Paredes Jairo , Muñoz Andrés
Published: June 2024

In Colombia, bricklaying is constituted as a very significant construction technique present in historical buildings. However, with changes in their use, which generally implied increased dynamic loads, strong environmental variations, increased pollution, and the presence of different living organisms – among other factors – in recent years have apparently accelerated the deterioration of the materials conforming them (brick and lime mortar), in many occasions making it necessary to determine their physical and mechanical properties along with their chemical and mineralogical composition to diagnose the real state of the structure. This article explores the appropriate routines for such characterization to permit their future application in restoration processes of historical buildings. From the case study involving the masonry brick arch bridge constructed in the city of Buga (Valle del Cauca) during the second half of the 19th century, we will establish how mechanical analysis of the bricks allows having reference patterns of its resistance behavior; simultaneously, mineralogical characterization permits identifying the composition and firing temperature of the bricks originally used in the construction.

“AI Will Be the Beating Heart of the City”: Connectivity and/as Care in The Line
Authors: Kopitz Linda
Published: June 2024

Artificial intelligence will be “the beating heart” (Bell, 2022, para. 1) of the linear smart city The Line in Saudi Arabia, one of the most expensive and expansive urban living projects of our times—and crucial in the larger vision of a post-oil future for Saudi Arabia. Exemplary of the complex relationship between past and future in constructing alternative urban imaginaries, the promotional material of The Line highlights technology as the best—and apparently only—solution to “maintain, continue, and repair our ‘world’ so that we can live in it as well as possible” (Tronto & Fisher, 1990, p. 40), while at the same time imagining artificial intelligence itself as a living and “organic” presence in the urban. Following David Pinder’s understanding of cities as always both imagined and real, immaterial and material, this article draws on care as a critical lens to explore the construction of The Line in answer to Nick Dunn’s provoking question: “So can imagining the future change it?” (Dunn, 2018, p. 376). Tracing “care in a manufactured landscape” (Mattern, 2021, p. 144) here highlights the entanglement between technology and sustainability, between organic metaphors and artificial environments, between virtual connection and material exhaustion. Critically examining the promise embedded in contemporary architectural projects to deliver “new and imaginative solutions” (NEOM, 2022e) for the physical, psychological, and environmental exhaustion of urban life, this article proposes an understanding of connectivity and care as increasingly entangled—and argues that the urban vision put forward in The Line, ultimately, hinges on care as connectivity rather than caring interconnections, networked logics rather than networks of belonging.

Оne of the most commonly used fluorine‑18 labeled prostate-specific membrane antigen (PSMA) ligands in positron emission tomography combined with computed tomography (PET/CT) is [18F]PSMA‑1007. In comparison to other clinically available PSMA radioligands characterized by renal clearance, [18F]PSMA‑1007 exhibits predominantly hepatobiliary excretion. It allows a better assessment of the pelvic area in patients with prostate cancer (PCa). Nevertheless, in our clinical practice, we routinely observed a notably high [ 18F]PSMA‑1007 uptake in the urinary bladder. The underlying reasons for this phenomenon remain inadequately explored.

Purpose of the study. The purpose of this study was to assess the impact of preliminary hydration of patients on [18F]PSMA‑1007 uptake in the urinary bladder.

Materials and methods. Prospective, multicenter, randomized controlled study included 180 patients with PCa who underwent [18F]PSMA‑1007 PET/CT. Scans were performed using three different PET/CT-systems: GE Discovery IQ Gen 2 (USA), Siemens Biograph 64 mCT and Biograph 64 TruePoint (Germany). All patients were divided into two groups: the group with hydration (n = 95, 53 %), which included the subgroups of patients with oral (n = 76, 80 %) and intravenous (n = 19, 20 %) routes of hydration, and the control group with no hydration (n = 85, 47 %). [18F]PSMA‑1007 uptake in the urinary bladder was quantified using SUVmean (Mean Standardized Uptake value), measured within a spherical VOI with a fixed volume of 2.5 cm3 delineating the bladder boundaries. Additionally, the TBRmean (Mean Target-to-Background Ratio), reflecting the ratio between urinary bladder and right gluteal muscles SUVmean.

Results. SUVmean and TBRmean in urinary bladder were significantly lower (p < 0,001) in the group with hydration compared to the control group, with the following values: 1.3 [0.8; 2.0] versus 4.5 [2.7; 8.5] for SUVmean and 4.0 [2.3; 6.3] versus 13.0 [7.7; 24.0] for TBRmean. There was no significant differences in SUVmean and TBRmean between the subgroups with oral and intravenous routes of hydration (p = 0.95 for SUVmean, p = 0.49 for TBRmean). Additionally, comparatively lower interquartile range (IQR) values for both SUVmean and TBRmean in the group with hydration were noted: 1.2 versus 5.8 for SUVmean, 4.0 versus 16.3 for TBRmean.

Numerical and experimental methods are used to solve a multidisciplinary problem on determining the stress state of a steel shell of revolution under mechanical loading and thermal effect with allowance for its contact with a hydrogen-containing medium. The study uses a well-developed mathematical tool for solving heat conduction problems in order to solve the problem of hydrogen diffusion into metal. The effective stresses and their invariants are determined by solving the nonlinear boundary value problem of thermoplasticity of a thick-walled shell of revolution in a three-dimensional formulation. The study takes into account the experimentally found effect of changes in the mechanical properties of steel affected by hydrogen. The correctness of the proposed method and the performed calculations is quantitatively estimated by comparison with a well-known problem having an analytical solution. The paper shows that it is possible and necessary to take into account the change in mechanical properties when determining the stress state of steel structures operating in contact with a hydrogen-containing medium.

Interlayer defects in structural components made of composite materials are caused by the imperfection of the manufacturing process, complex interactions of the constituents, and the effect of impact loads. The presence of these defects decreases the strength of such components and severely affects residual strength. The paper presents a numerical and experimental study of the behavior of a composite material plate with a variable layup angle under impact loading. Impactor velocities before and after multilayer plate perforation, as well as the dimensions of delamination-type defects, are determined experimentally. The Ansys LS-DYNA software in double precision mode is used to simulate the failure of composite plates under impact loading. It has been found that a significant contribution to the decrease in the impact energy is made by the delamination dimensions depending on the layup angle in the stack. The delamination area is related to the residual velocity of the impactor; namely, the larger the delamination area, the greater the decrease in the impactor velocity.

BACKGROUND: Despite the retentive relevance of preeclampsia (PE) among the main causes of maternal morbidity and mortality, its etiology remains unclear. Despite gaps in its pathophysiology, highly effective methods of prognosis, prevention, and treatment are still not devised yet. In recent years, the use of microRNA molecules that epigenetically control the expression of target genes at the post-transcriptional level received great interest as are they of key importance in the proliferation, differentiation, invasion, migration, and apoptosis of trophoblast cells and regulation of angiogenesis, immune response, and other processes during pregnancy
AIM: This study aimed to investigate the epigenetic mechanisms of PE development based on the evaluation of the expression of pathogenetically significant microRNAs in women’s blood plasma.
MATERIALS AND METHODS: The study included 62 female patients divided into the main study group (n=42 with PE) and the control group (n = 20 healthy women with uncomplicated pregnancy, childbirth, and post-natal period). All patients have undergone general clinical, laboratory, and instrumental examinations. The expression levels of 15 microRNAs in the blood plasma were evaluated using a quantitative real-time polymerase chain reaction. DIANA miRPath v. 3.0 was used to evaluate the effect of differentially expressed microRNAs on the functioning of signaling pathways. Statistical data analyses were performed using Statistica 6.0.
RESULTS: Multidirectional changes in the expression levels of 13 of 15 plasma microRNAs were found in the PE group compared with the control group; however, the expression levels of the following eight microRNAs decreased significantly: hsa-miR-146a-5p (p=0.011), hsa-miR-181a-5p (p=0.015), hsa-miR-210-3p (p=0.031), hsa-miR-517a-3p (p=0.004), hsa-miR-517c-3p (p=0.007), hsa-miR-574-3p (p=0.048), hsa-miR-574-5p (p=0.003), and hsa-miR-1304-5p (p=0.001). The expression levels of hsa-miR-20a-5p (FC=0.39; p=0.049) and hsa-miR-143-3p (FC=0.71, p=0.05) significantly decreased in pregnant women with PE and symptoms of fetal growth retardation (FGR) compared with the subgroup without FGR. No significant differences in the expression level of the analyzed microRNAs were found between the subgroups with moderate and severe PE and early and late PE. The functional evaluation of differentially expressed microRNAs among women with PE, considering the identification of their potential target genes, revealed the dysregulation of 40 signaling pathways and biological processes in which these molecules are involved.
CONCLUSION: PE progresses alongside significant epigenetic changes accompanied by changes in the microRNA expression profile, which are associated with cardiovascular and cerebrovascular diseases and placental disorders. The detected differentially expressed microRNAs may be potential diagnostic markers of PE.

A Note on Exact Closed-Form Solutions for Lamb’s Problem with an Arbitrary Poisson’s Ratio
Authors: Hu Shaoqian , Jiang Xiaohuan
Published: June 2024

Lamb’s Problem, a cornerstone in theoretical seismology, investigates the displacement of an elastic half-space due to surficial or buried point sources. Although the exact closed-form solution for surface displacements from surficial sources is well established, the solutions for buried sources in the 3D case have remained limited, either confined to integral forms or applicable only for certain Poisson’s ratios. This study addresses this gap by generalizing the existing closed-form solutions to accommodate Poisson’s ratio for buried sources. Our solutions are expressed in terms of elementary algebraic expressions, elliptic integrals, and Gauss hypergeometric functions. The derived solution is validated by numerical tests. With the newly derived solution, we also explore the properties of the leaking mode, which stems from the complex conjugate roots of the Rayleigh equation.
A Systematic Literature Review on Civic Engagement
Authors:   The Korea Association of Yeolin Education, Park Jinseo , Hong Ah-Jeong
Published: June 2024

Civic engagement activities are driven by policy expectations and utilities that focus citizen participation with the idea that they will lead to better outcomes. Depending on the level of direct participation, citizens can be categorized from dutiful to engaged citizens. Measures of citizenship, such as fostering a sense of ownership and active social participation, will ensure the sustainability of future societies and have a positive impact on democratic governance and economic development. A systematic review research method was applied to collect and characterize the literature on civic engagement measurement tools from 1994, when social capital research began to emphasize the importance of civic engagement, to the present. The results showed that civic engagement has expanded along with the changing roles and capacities of citizens required by society at large. Measurement analyses revealed that most instruments have very low levels of validity and reliability. When measuring civic engagement among adults who are active in their communities, there is a need to use instruments with a stronger measurement basis. There is a need to develop a civic engagement instrument that reflects the changing concept of citizenship and the nature of civic engagement and has good reliability and validity evidence.

Published: June 2024

This study sought to examine longitudinally how parental support affects career maturity through children's self-concept. For this purpose, data from the 3rd to 7th years of the KELS 2013 of the Korean Educational Development Institute were used. Descriptive statistics and a multivariate latent growth model were analyzed using five years of longitudinal data from 5,200 students nationwide from the first year of middle school to the second year of high school. As a result, first, parental support, children's self-concept, and career maturity showed a decreasing trend over time. Second, parental support at an early point in time had a positive effect on the children's self-concept and career maturity, and the children's initial self-concept had a positive effect on the initial career maturity. Additionally, changes in parental support had a significant positive effect on changes in children's self-concept. Meanwhile, changes in parental support appeared to be slowing down as they have a negative impact on changes in children's career maturity. Through this, it was confirmed that parental support is an important variable that determines a children's self-concept by influencing the children's self-concept from the beginning to the pattern of change. In addition, the higher the initial parental support, the higher the children's initial career maturity. However, changes in parental support showed a negative relationship with changes in career maturity, so the increase slowed. Based on this, it was suggested that follow-up research was needed to establish institutional alternatives to narrow the gap in students' self-concept and career maturity caused by differences in parental support in the educational field and, lastly, to identify the characteristics of each variable.

Published: June 2024

Although the introduction of modular curriculum is being discussed rapidly in university education, there is a lack of in-depth discussion on the awareness and demands of Microdegrees by learners.In this study, we attempted to provide implications for Microdegree curriculum design through a survey of college students' perceptions of Microdegrees. A survey was conducted separately between non-engineering and engineering majors on topics such as awareness of Microdegrees and willingness to participate in Microdegrees by type, and the results were analyzed. As a result of the analysis, many students responded that they did not know much about Microdegrees,while many students responded that Microdegree werea necessary system. Compared to non-engineering students (M=3.92), engineering students (M=4.11) thought it was an opportunity to improve their capabilities in their area of interest, and they also thought it would be helpful in career development. In a survey on the intention to participate in Microdegrees by type, the intention for ‘Company-linked Microdegree’ was the highest, regardless of whether it was a non-engineering or engineering field. This suggests that it is important for universities to discover Microdegrees that can demonstrate practical capabilities through close industry-academic linkages. In order for Microdegrees, which are limited to 12 credits, to be operated effectively and attractively, classesneed to be carefully designed. Microdegreesshould be operated as an effective curriculum for university education, reflecting learner awareness and some concerns about Microdegrees.
