Analysis of Long Time Series of Summer Surface Urban Heat Island under the Missing-Filled Satellite Data Scenario
Authors: Luo Jiamin , Yao Yuan , Yin Qiuyan
Published: November 2023

Surface urban heat islands (SUHIs) are mostly an urban ecological issue. There is a growing demand for the quantification of the SUHI effect, and for its optimization to mitigate the increasing possible hazards caused by SUHI. Satellite-derived land surface temperature (LST) is an important indicator for quantifying SUHIs with frequent coverage. Current LST data with high spatiotemporal resolution is still lacking due to no single satellite sensor that can resolve the trade-off between spatial and temporal resolutions and this greatly limits its applications. To address this issue, we propose a multiscale geographically weighted regression (MGWR) coupling the comprehensive, flexible, spatiotemporal data fusion (CFSDAF) method to generate a high-spatiotemporal-resolution LST dataset. We then analyzed the SUHI intensity (SUHII) in Chengdu City, a typical cloudy and rainy city in China, from 2002 to 2022. Finally, we selected thirteen potential driving factors of SUHIs and analyzed the relation between these thirteen influential drivers and SUHIIs. Results show that: (1) an MGWR outperforms classic methods for downscaling LST, namely geographically weighted regression (GWR) and thermal image sharpening (TsHARP); (2) compared to classic spatiotemporal fusion methods, our method produces more accurate predicted LST images (R2, RMSE, AAD values were in the range of 0.8103 to 0.9476, 1.0601 to 1.4974, 0.8455 to 1.3380); (3) the average summer daytime SUHII increased form 2.08 °C (suburban area as 50% of the urban area) and 2.32 °C (suburban area as 100% of the urban area) in 2002 to 4.93 °C and 5.07 °C, respectively, in 2022 over Chengdu City; and (4) the anthropogenic activity drivers have a higher relative influence on SUHII than other drivers. Therefore, anthropogenic activity driving factors should be considered with CO2 emissions and land use changes for urban planning to mitigate the SUHI effect.

Published: November 2023

Effective response strategies to earthquake disasters are crucial for disaster management in smart cities. However, in regions where earthquakes do not occur frequently, model construction may be difficult due to a lack of training data. To address this issue, there is a need for technology that can generate earthquake scenarios for response training at any location. We proposed a model for generating earthquake scenarios using an auxiliary classifier Generative Adversarial Network (AC-GAN)-based data synthesis. The proposed ACGAN model generates various earthquake scenarios by incorporating an auxiliary classifier learning process into the discriminator of GAN. Our results at borehole sensors showed that the seismic data generated by the proposed model had similar characteristics to actual data. To further validate our results, we compared the generated IM (such as PGA, PGV, and SA) with Ground Motion Prediction Equations (GMPE). Furthermore, we evaluated the potential of using the generated scenarios for earthquake early warning training. The proposed model and algorithm have significant potential in advancing seismic analysis and detection management systems, and also contribute to disaster management.
PC-ILP: A Fast and Intuitive Method to Place Electric Vehicle Charging Stations in Smart Cities
Authors: Bose Mehul , Dutta Bivas Ranjan , Shrivastava Nivedita , Sarangi Smruti R.
Published: November 2023

The widespread use of electric vehicles necessitates meticulous planning for the placement of charging stations (CSs) in already crowded cities so that they can efficiently meet the charging demand while adhering to various real-world constraints such as the total budget, queuing time, electrical regulations, etc. Many classical and metaheuristic-based approaches provide good solutions, but they are not intuitive, and they do not scale well for large cities and complex constraints. Many classical solution techniques often require prohibitive amounts of memory and their solutions are not easily explainable. We analyzed the layouts of the 50 most populous cities of the world and observed that any city can be represented as a composition of five basic primitive shapes (stretched to different extents). Based on this insight, we use results from classical topology to design a new charging station placement algorithm. The first step is a topological clustering algorithm to partition a large city into small clusters and then use precomputed solutions for each basic shape to arrive at a solution for each cluster. These cluster-level solutions are very intuitive and explainable. Then, the next step is to combine the small solutions to arrive at a full solution to the problem. Here, we use a surrogate function and repair-based technique to fix any resultant constraint violations (after all the solutions are combined). The third step is optional, where we show that the second step can be extended to incorporate complex constraints and secondary objective functions. Along with creating a full software suite, we perform an extensive evaluation of the top 50 cities and demonstrate that our method is not only 30 times faster but its solution quality is also 36.62% better than the gold standard in this area—an integer linear programming (ILP) approach with a practical timeout limit.
The Impact of Local Government Environmental Target Constraints on the Performance of Heavy Pollution Industries
Authors: Xu Hong , Lin Kai , Qiu Lei
Published: November 2023

The world is plagued by difficult problems such as ecological degradation and resource depletion. This study utilizes data from 664 Shanghai and Shenzhen A-share listed enterprises in the heavy pollution industry from 2007 to 2019; this paper constructs a two-way fixed effects panel model and a mediated effect model to test the relevant effects of local government environmental target constraints (LGETCs) on the performance of heavy pollution enterprises (HPEs). The main findings are as follows: First, LGETCs significantly inhibit the short-term performance of HPEs. Second, LGETCs have a heterogeneous impact on the short-term performance of HPEs based on regional, industry, and firm ownership differences. This sentence suggests that local environmental targets can exert a restraining effect on the short-term performance of heavily polluting companies by influencing factors such as financial constraints, agency costs, and levels of technological innovation. In this context, financial constraints and agency costs act as mediating factors, while corporate technological innovation and green technological innovation act as masking factors in this relationship. The sentence appears to suggest that local environmental targets can indirectly have a positive impact on the long-term performance of heavily polluting companies through innovative incentives. Furthermore, the research in this article provides theoretical support for local government efforts to address deteriorating ecological environments and expedite energy conservation and emission reduction in heavily polluting companies.
The Uptake of Rare Trace Elements by Perennial Ryegrass (Lolium perenne L.)
Authors: Jensen Hayley , Lehto Niklas , Almond Peter , Gaw Sally , Robinson Brett
Published: November 2023

Technological development has increased the use of chemical elements that have hitherto received scant scientific attention as environmental contaminants. Successful management of these rare trace elements (RTEs) requires elucidation of their mobility in the soil–plant system. We aimed to determine the capacity of Lolium perenne (a common pasture species) to tolerate and accumulate the RTEs Be, Ga, In, La, Ce, Nd, and Gd in a fluvial recent soil. Cadmium was used as a reference as a well-studied contaminant that is relatively mobile in the soil–plant system. Soil was spiked with 2.5–283 mg kg−1 of RTE or Cd salts, representing five, 10, 20, and 40 times their background concentrations in soil. For Be, Ce, In, and La, there was no growth reduction, even at the highest soil concentrations (76, 1132, 10.2, and 874 mg kg−1, respectively), which resulted in foliar concentrations of 7.1, 12, 0.11, and 50 mg kg−1, respectively. The maximum no-biomass reduction foliar concentrations for Cd, Gd, Nd, and Ga were 0.061, 0.1, 7.1, and 11 mg kg−1, respectively. Bioaccumulation coefficients ranged from 0.0030–0.95, and increased Ce < In < Nd ≅ Gd < La ≅ Be ≅ Ga < Cd. Beryllium and La were the RTEs most at risk of entering the food chain via L. perenne, as their toxicity thresholds were not reached in the ranges tested, and the bioaccumulation coefficient (plant/soil concentration quotient) trends indicated that uptake would continue to increase at higher soil concentrations. In contrast, In and Ce were the elements least likely to enter the food chain. Further research should repeat the experiments in different soil types or with different plant species to test the robustness of the findings.

Authors: Corrales-Gutierrez Isabel , Gomez-Baya Diego , Leon-Larios Fatima , Medero-Canela Rocío , Marchei Emilia , Mendoza-Berjano Ramon , García-Algar Óscar
Published: November 2023

(1) Background: Alcohol consumption during pregnancy is a major concern, particularly in Europe and North America. Its prevalence has so far been under-researched. In most studies, the determination of this consumption may be underestimated, as it is based on the information obtained from questionnaires rather than from biomarkers, which will provide a much more reliable approach. The main objective of this study was to compare the prevalence of consumption during pregnancy as assessed by a questionnaire and a hair biomarker. (2) Method: A cross-sectional study with a random sample of 425 pregnant women treated in public hospital consultations in Seville (Spain) and in the 20th week of their pregnancy, orally interviewed using an elaborated ad hoc questionnaire that evaluated variables of sociodemographic, obstetric, and alcohol consumption. Furthermore, the ethyl glucuronide metabolite (EtG) was tested on a hair sample in 252 pregnant women who agreed to facilitate it. Once the data obtained through the questionnaire and hair test were analyzed, the level of metabolites and self-reported alcohol consumption were compared. (3) Results: The prevalence of self-reported alcohol consumption (questionnaire) was 20.7%, and the real consumption (metabolite analysis) was 20.2%. In 16.8% of pregnant women who declared not consuming alcohol during their pregnancy, noticeable consumption was detected according to the metabolite test. No relevant level of variability in estimated alcohol consumption was detected in the biomarker with respect to the sociodemographic and obstetric variables studied. (4) Conclusions: The prevalence of alcohol consumption during pregnancy obtained through both questionnaires and metabolite analyses was similar and high. There is no association between consumption and sociodemographic factors in this sample. The determination of consumption through biomarkers allows for a more accurate approximation of the prevalence of consumption than estimated through questionnaires. Larger sample-sized studies are needed to determine consumption patterns and thus guide the adoption of more precise policies fostering abstinence from alcohol consumption since the preconception period.

Published: November 2023

The educational and play-related activities of children proceed mainly indoors in a kindergarten. High concentrations of indoor PM2.5 and CO2 have been linked to various harmful effects on children, considerably impacting their educational outcomes in kindergarten. In this study, we explore different scenarios involving the operation of mechanical ventilation systems and air purifiers in kindergartens. Using numerical models to analyze indoor CO2 and PM2.5 concentration, we aim to optimize strategies that effectively reduce these harmful pollutants. We found that the amount of ventilation required to maintain good air quality, per child, was approximately 20.4 m3/h. However, we also found that as the amount of ventilation increased, so did the concentration of indoor PM2.5; we found that this issue can be resolved using a high-grade filter (i.e., a MERV 13 grade filter with a collection efficiency of 75%). This study provides a scientific basis for reducing PM2.5 concentrations in kindergartens, while keeping CO2 levels low.

Published: November 2023

Human parvovirus B19 (B19V) has a wide clinical spectrum, ranging from an asymptomatic infection to a life threatening one. During pregnancy, it can lead to fetal loss and hydrops fetalis. This retrospective study examined the incidence rates of B19V in Israel, analyzing anonymized electronic medical records of 2.7 million individuals between January 2015 and September 2023. A generalized linear model with a Poisson distribution was fit to the data, adjusting for potential confounders. A marked increase in B19V was observed in 2023, with an adjusted incidence rate ratio (IRR) of 6.6 (95% CI 6.33–6.89) when comparing 2023 to previous years. When specifically comparing 2023 to COVID-19 years (2020–2022), adjusted IRR climbs to 9.21 (8.66–9.80). Moreover, in 2023, previously existing seasonality has largely disappeared. High SES characterized most infected individuals with a marked discrepancy in social sectors; the Arab population was significantly less likely to be found B19V positive, even when adjusting for SES. Most infections occurred in school-aged children (6–11 years old). Pregnant women experienced the most significant rise in B19V, with an adjusted IRR of 11.47 (9.44–13.97) in 2023 compared to previous years; most cases were diagnosed in the first trimester. This study demonstrates that Israel is currently experiencing the largest and longest reported outbreak of B19V to date. Policymakers should consider setting screening policies in place, at least for populations at risk, while specifically studying and potentially targeting low socioeconomic populations and specific social sectors to avoid health inequalities.

Published: November 2023

In the wake of increasingly frequent bushfires emerging as a threat to wildlife worldwide, koalas have notably been the most rescued species in Australia. However, our understanding of burns and their severity in koalas is limited; hence, this study investigated the histopathological features and depth of burns in koala skin, as well as the presence of smoke-induced respiratory tract damage. In four bushfire-affected koalas that had been euthanised on welfare grounds, skin burns in various body regions were scored based on clinical appearance as superficial, partial thickness, or full thickness. Histological sections of affected regions of skin were assessed as Grades I–IV and showed that furred regions on the ear margins and dorsum were histologically more severe, at Grade III, compared with the clinical score. There was a similar finding for footpad burns, which were the most common body region affected. In the respiratory tract, pulmonary oedema and congestion were evident in all koalas. Overall, the results highlight that cutaneous burn lesions on furred and palmar/plantar surfaces can have higher severity based on the burn depth than is clinically apparent. Therefore, there is a need to consider this when developing treatment plans and establishing prognosis for burnt koalas at triage, as well as that a high likelihood of pulmonary oedema exists.

Published: November 2023

Canine atopic dermatitis (cAD) is a common and distressing skin condition in dogs, affecting up to 30% of the canine population. It not only impacts their quality of life but also that of their owners. Like human atopic dermatitis (hAD), cAD has a complex pathogenesis, including genetic and environmental factors. Current treatments focus on managing clinical signs, but they can be costly and have limitations. This article emphasizes the importance of preventing cAD from developing in the first place. Understanding the role of the skin’s protective barrier is crucial, as its dysfunction plays a vital role in both hAD and cAD. hAD prevention studies have shown promising results in enhancing the skin barrier, but more research is needed to support more robust conclusions. While hAD primary prevention is currently a focal point of intensive investigation in human medicine, research on cAD primary prevention remains under-researched and almost non-existent. Pioneering effective prevention strategies for cAD holds immense potential to enhance the quality of life for both dogs and their owners. Additionally, it bears the promise of a translational impact on human research. Hence, further exploration of this crucial topic is not only relevant but also timely and imperative, warranting support and encouragement.

The method used in this study is a normative juridical approach, the data obtained were analyzed qualitatively juridically by taking into account the hierarchy of provisions. current regulation. The results of this study indicate that people have rights to themselves and can determine what is best for their bodies, including vaccines. The covid 19 pandemic that hit Indonesia affected various sectors, from the health sector to the economy. The government as a representative of the state in protecting all levels of society takes the necessary steps to tackle the spread of covid 19 by making decisions to limit community activities and also decisions to provide vaccines to the community and require vaccines for people who have been designated as the target recipients of the covid 19 vaccine. Article 5 paragraph (3) of Law No. 36 of 2009 concerning Health states that the public as vaccine recipients have autonomous rights over themselves. However, during a pandemic, the government may oblige to vaccinate people who have been designated as the target recipients of the covid 19 vaccine based on Article 13A paragraph (2) of Presidential Regulation of the Republic of Indonesia Number 14 of 2021 concerning Amendments to Presidential Regulation Number 99 of 2020 concerning Vaccine Procurement and Implementation of Vaccination in the Context of Combating the Covid 19 Pandemic.
TORSION OF LOWER BELT OF CRANE SECONDARY TRUSS
Authors: Markina Yu.
Published: November 2023

The lower belt of the crane secondary truss, along which the crane moves, is made of a thin-walled box profile. The largest local concentrated crane forces applied with eccentricity to the lower belt of truss made of thin-walled welded box cause its restrained torsion. The calculation method of the crane secondary truss does not consider the inclusion in the work of the lower belt for torsion and horizontal bending of the webs. A beam with a span equal to the span of the crane secondary truss is taken as the design scheme of the lower belt along which the crane moves. In fact, the work of the belt during torsion is different from the work of the beam.

The objectives of the work are to assess the impact on the operation of the lower belt during torsion of the webs and the upper belt and to clarify the methodology for calculating the lower belt. The study of the influence of webs on the angular malleability and torque of the lower belt has been carried out. Various ratios of the stiffness of the belt and the entire crane secondary truss are considered. The design scheme of the belt for the calculation of torsion is proposed – a beam angular elastic supports at the points of junction of the webs. The formula for determining the stiffness of elastic supports has been adopted. The error in determining the bending moments in the lower belt according to the proposed method relative to the results of numerical calculation of the rod design scheme of the entire crane secondary truss does not exceed 2%. The stresses in the lower belt, considering the torsion component, are analytically determined. The results were verified numerically using shell finite elements and a full-scale examination.

Published: November 2023

The presented article describes the technology of topological optimization. The main methods of topological optimization are also described: ESO/BESO; SIMP-method; ESO-Simp-method; Level-Set-method. Each of the methods has its advantages, but they have common disadvantages, namely: the problem of the "chessboard" and the dependence on grid partitioning. Topological optimization allows you to reduce the weight of the product, while maintaining the strength characteristics. Based on the product obtained after optimization, its production technologies were considered. These include traditional technologies (casting, stamping, milling, etc.) and additive manufacturing technologies. Software with topological optimization functionality was presented and described. These are mainly commercial CAD/CAE systems (OptiStruct, Simulia Tosca, ANSYS and MSC Nastran). The main industries that use the method of topological optimization are the aerospace industry, mechanical engineering, medicine, robotics and others. In this paper, we consider the process of reducing the weight of a robotic cell trolley using the SIMP (Solid Isotropic Material with Penalization) method, on which a robotic arm is attached. The functionality of the CAD/CAM/CAE-system NX from Siemens PLM Software was used for the topological optimization of the robotic cell trolley. Generalizing conclusions are made that topological optimization makes it possible to obtain geometric shapes of a product with a minimum mass while maintaining strength and rigidity.

En el contexto de la asignatura de Ciencia e Ingeniería de los Materiales (CIM), común para todos los grados de ingeniería de la rama industrial de la Escuela Técnica Superior de Ingeniería de Algeciras (ETSIA), se comparan indicadores de calidad tras aplicar dos aproximaciones de evaluación continua: una más tradicional mediante exámenes escritos de bloques temáticos, y otra mediante una metodología docente con el objetivo de que los alumnos sean los responsables de la asimilación del conocimiento. En esta nueva metodología, el 100% de la evaluación es en forma de evaluación continua. Parte de esta evaluación es en forma de pruebas de progreso, donde cada tema lo han tenido que aplicar a un caso práctico, para el cuál se les daba una semana para resolverlo. Otra peculiaridad de esta segunda aproximación de evaluación continua es que la entrega de la prueba se realiza en distintos formatos: modelos CAD, hojas de cálculo, vídeos, exposiciones, etc. Con esta metodología se persigue hacer al alumnado responsable de su propio proceso de aprendizaje, siendo parte activa del mismo. De forma generalizada se puede concluir que el sistema de evaluación continua mejora, además de las calificaciones obtenidas en la asignatura, el rendimiento posterior de los alumnos y su actitud hacia el aprendizaje autónomo.
ВЗАЄМОЗВ’ЯЗОК ГЕНДЕРНИХ ТА КЛІНІКО-ПСИХОЛОГІЧНИХ ОСОБЛИВОСТЕЙ НЕВРОТИЧНО ХВОРИХ
Authors: Абсалямова Лариса , Чернець Богдан
Published: November 2023

Актуальність дослідження. Наразі у психологічній літературі відсутні систематизовані уявлення щодо психологічних особливостей оцінки хворими на невротичні розлади якості свого життя, що, у свою чергу, підкреслює необхідність проведення спеціального комплексного психодіагностичного дослідження, спрямованого на аналіз оцінки якості життя.

Мета. Стаття присвячена викладу матеріалів експериментального дослідження взаємозв’язку гендерних та клініко-психологічних особливостей хворих на невроз.

Результати. Показано, що якість життя після лікування чоловіки з невротичними розладами оцінили вище, аніж жінки, у сфері особистих вірувань, духовних і релігійних переконань, у сфері фінансових ресурсів, і сфері задоволеності своєю зовнішністю і образом тіла. В той же час жінки з невротичними розладами навіть після лікування не змогли оцінити якість свого життєвого функціонування ні в одній сфері вище, аніж чоловіки.

Висновки. У пацієнтів з невротичними розладами обох статей в процесі терапії відбувається редукція психопатологічної симптоматики, зменшується її тяжкість, різноманітність симптомів і у зв’язку з цим знижується рівень дистресу, викликаного соматичним і психологічним неблагополуччям. В якості основних психотерапевтичних завдань при лікуванні пацієнтів із невротичними розладами повинні виступати: корекція ірраціональних вимог відносно себе, а також ірраціональних установок катастрофізації, з метою формування адекватнішого ставлення до себе і до оточуючих.. Рекомендується також закріплення конструктивних механізмів копінгу, таких як «Планування вирішення проблеми», «Пошук соціальної підтримки» і «Прийняття відповідальності» і зниження частоти використання неконструктивних форм поведінки, зокрема «Уникнення». Психотерапевтичними мішенями повинні виступати основні компоненти стосунків особистості: когнітивний, емоційний і поведінковий, а психотерапевтична дія в цілому повинна сприяти розширенню сфери самосвідомості, поліпшенню самопізнання, набуттю навичок конструктивнішої поведінки і саморегуляції.. Результати виявлення взаємозв'язків клініко-психологічних показників і рівня якості життя хворих дозволять визначати і контролювати ефективність проведеної психотерапії.
АДАПТИВНІ СТРАТЕГІЇ ОРГАНІЗАЦІЇ НАВЧАЛЬНОЇ ДІЯЛЬНОСТІ СТУДЕНТІВ ЗВО
Authors: Кузікова Світлана , Щербак Тетяна
Published: November 2023

У статті подано результати теоретико-емпіричного дослідження стратегій поведінки студентів ЗВО в різних ситуаціях навчальної діяльності; проаналізовано ефективність використання копінгів у ситуаціях академічного стресу, визначено рівень прокрастинації студентів з різними домінуючими копінг-стратегіями.

Мета дослідження. Визначити адаптивні стратегії організації навчальної діяльності студентів ЗВО в залежності від прокрастинації та рівня оптимізму.

Вибірка і методи дослідження. Дослідження проводилося серед 66 студентів 2-4 курсів (середній вік респондентів 20,8 років) Сумського державного педагогічного університету ім. А. С. Макаренка. Діагностичний інструментарій складали наступні методики: «Тест на визначення рівня оптимізму Л. М. Рудіної» (на основі «Attributional style questionnare» М. Е. Селігмана), «Копінг-тест Лазаруса» (адаптований Т. Л. Крюковою, Є. В. Куфтяк, М. С. Замишляєвим) та «Шкала загальної прокрастинації Tuckman» (адаптація Т. Л. Крюкової).

Результати. З’ясовано, що найбільш вираженими стратегіями поведінки осіб із низьким рівнем прокрастинації є позитивна переоцінка та планування. За результатом аналізу теоретичних джерел встановлено, що найчастіше за значущістю для прокрастинатора емоційний компонент домінує над когнітивним (відкладають справи через тривожність та негативні емоційні переживання, а не через нездатність спланувати свій час і ресурси). Застосувавши кореляційний аналіз rs Спiрмена, значущих зв’язків між рівнем оптимізму досліджуваного та вираженістю копінгу «позитивна переоцінка» виявлено не було. Гіпотезу про кореляцію між оптимізмом та низьким рівнем прокрастинації студентів не верифіковано.

Висновки та перспективи. Схильність особистості до позитивної інтерпретації подій та оптимістичних очікувань впливає на підвищення адаптивності та стресостійкості, зменшує вірогідність деструктивних та дезадаптивних стратегій поведінки. Позитивна переоцінка впливає на характер інтерпретації людиною ситуацій, причин подій та умов об'єктивної реальності, сприяє пошуку нових рішень і можливостей; є впливовою на характер очікувань, що постає важливим фактором впливу на рівень прокрастинації і зменшує вірогідність пасивних уникаючих копінгів, сприяє вибору активних копінг-стратегій та збереженню продуктивної діяльності. Недостатня вираженість та різноманітність арсеналу стратегій поведінки є фактором зниження можливостей до адаптації та ефективної діяльності особистості при перебуванні під впливом стресогенних факторів, і, як наслідок, веде до підвищення прокрастинації.

Дані, отримані при емпіричному дослідженні, можуть слугувати для подальшого вивчення питань впливу явища оптимізму на продуктивність діяльності та його зв’язків із стратегіями поведінки особи у стресових ситуаціях. Результати щодо ефективності певних копінг-стратегій для зниження рівня академічної прокрастинації можуть стати основою для розробки рекомендацій щодо підвищення якості навчальної діяльності студентів.

Актуальність дослідження. Проблема психологічної готовності батьків дітей дошкільного віку в тому числі з особливими освітніми потребами набуває високої значущості та впливає на ефективність реалізації інклюзивної освіти сьогодення.

Мета дослідження. Теоретичний аналіз психологічної готовності батьків дітей дошкільного віку до інклюзивної освіти та здійснення емпіричного дослідження.

Результати і висновки. Проведене нами емпіричне дослідження, надало можливість зробити висновок, що у респондентів недостатньо сформовано когнітивний компонент психологічної готовності. Батьки здебільшого не знають, що таке інклюзивна освіта, у них майже відсутні уявлення про сутність та зміст інклюзивної освіти. Емоційний та мотиваційний компоненти готовності батьків дітей дошкільного віку мають свої особливості для респондентів обох груп. Для батьків дітей з ООП, мотивуючими факторами є рівноцінне ставлення до їх дітей, почуття повноцінності дитини та позитивний вплив на соціалізацію в суспільство. В той же час у батьків дітей з нормальним психофізичним розвитком виявлені побоювання у міжособистісних стосунках між дітьми, між дітьми та вихователями, недостатність уваги з боку педагогів до їх дітей та зниження пізнавального інтересу. Можемо стверджувати, що батьки не готові до виховання і навчання дітей в інклюзивній групі закладу дошкільної освіти. Все вищезазначене свідчить про те, що необхідно формувати психологічну готовність батьків дітей дошкільного віку до інклюзивної освіти.

Published: November 2023

This study examines the impact of sukuk issued by participation banks and the state on economic growth in Türkiye. In this direction, econometric analysis was conducted between 2013Q1-2022Q4 using Johansen cointegration and VECM Granger causality tests. Our findings show that sukuk issuance and economic growth move together in the long run. Subsequently, according to the long-term coefficient results, the effect of sukuk issued by participation banks on economic growth was found to be positive and significant, while the sukuk issued by the state did not have a significant effect on economic growth. In addition, according to the Granger causality test results, it was determined that there is a one-way causality relationship from GDP to participation banks’ sukuk issuance. Our results show that the issuance of sukuk both contributes to and benefits from economic growth.

The demand for more efficient energy storage devices with a sustainable approach has turned supercapacitors into a great alternative in applications where high instantaneous power is required. Above all, those based on manganese oxides are attracting attention for their low cost, durability, and relatively high specific capacitance. However, it is known that MnO2 with a pyrolusite structure (β-MnO2) has a poor performance. This work studies this material electrochemically before and after thermally incorporating potassium cations at 800 °C. For the present work, commercial MnO2 and MnO2 doped with potassium ions (K-MnO2) were used as active material for the electrodes of commercial supercapacitors. It was verified that the commercial material is β-MnO2 and that the thermally doped material is predominantly manganese oxide with a cryptomelane structure (α-KxMnO2). Cyclic voltammetry measurements were performed at different scanning rates, to elucidate the electrochemical response of the materials. The results corresponding to K-MnO2 present a higher current compared to commercial MnO2, this implies that this electrode has a higher specific capacitance, which can be attributed to a greater potassium ion insertion/extraction capacity. However, at high scanning speeds, its behavior shows that it is pseudocapacitive.

Microbial fuel cells are electrochemical devices that use microorganisms as catalysts to produce electricity. Oxygen is the most used electron acceptor in the cathodic reaction of these systems, due to its abundance in the environment and high redox potential; however, the slow kinetics in oxygen reduction constitutes a limitation. Platinum (Pt) is the most widely used catalyst to accelerate the oxygen reduction reaction, but its high cost makes its use on a large scale impossible. In this study, the performance of manganese dioxide (MnO2) as a cathodic catalyst in an H-type microbial fuel cell was examined. The MnO2 layer on the carbon fiber surface was deposited by simply immersing the carbon in an aqueous KMnO4 solution. The microbial fuel cell was characterized by polarization and power curves. A maximum power peak of 6.09 mW/m2 was obtained with a current density of 22 mA/m2, showing that MnO2 can be a low-cost alternative to be used as catalytic material in the cathode of these devices.

In the development of the cultural and creative industry, popular cultural and creative attractions are reviewed for integrating local architecture, history, and culture into products to promote local economy and culture. We conducted a field investigation at the Xiaojia ancient house in Jiadong Township, Pingtung County, and found that there was a cultural cognitive gap between local cultural and creative products and consumers, which was a dilemma in promoting the development of the local cultural and creative industry. Through the design thinking of cultural and creative products, the spirit of Hakka culture can be delivered and expanded into local specialty products. In the design of cultural and creative products, we used the KJ method to analyze, summarize, and extract the most representative architectural features as the source of design elements. At the same time, combined with the principles of design semiotics, deep cultural symbols were integrated into the product design of the pen holder with richer local spiritual meaning. The traditional and modern elements of the Xiao family’s ancient house were combined to design a multi-functional cultural and creative pen holder. It brought a unique cultural experience and promoted the local cultural and creative industries and the Hakka culture of Xiaojia Ancient House to develop related culture and tourism. Semiotics and the KJ method in theory and practice were useful in product design and programming to develop local cultural and creative products. In the future, we apply this design method to different cultures and cross-domains to achieve wider research and application.

We investigated the light shift of Ramsey coherent population trapping (CPT) resonance by drive current modulation (DCM), which can be realized with low power consumption in a small system, to improve the performance of a CPT atomic clock. The light shift makes the greatest contribution to the degradation of long-term frequency stability of a CPT atomic clock. We also devised digitizer-based DCM to reduce the uncertainty in the frequency of light shift due to wavelength variation at the time of observation. The results show that light shift with DCM is reduced compared with cw excitation and is consistent with theoretical calculations. The estimated frequency uncertainty of the light shift due to wavelength variation using the proposed method is 2.1 × 10−13, which is approximately 165 times better than that of the conventional method without a digitizer, thus demonstrating the effectiveness of the proposed method for future small atomic clocks.

We describe a portable 32-antenna coherent passive radar system. The system was developed with space domain awareness in mind, but can be used for aircraft and nearer objects. We describe the physical and signal processing architecture and the results of a system test using VHF-band broadcast transmitters as illuminators. Using a combination of phased-array beamforming and delay/Doppler tracking, the flight path of a small training aircraft was tracked with high accuracy in excellent agreement with public flightpath data.

In this paper, there is a novel model based on ensemble learning for predicting phishing websites. The overall design is a combination of three individual machine-learning models with the help of the uni-variate feature selection model for detecting phishing and non-phishing URLs. The proposed model can minimize the error rate and provide improved accuracy with a short execution time. As compared with other traditional models, this model has higher performance metrics for detecting phishing websites compared with traditional machine learning and deep learning models.  
Cross Talking TDC
Authors: Xiang Li
Published: November 2023

A pulse stretching Time to Digital Converter (TDC) exploits the crosstalk effect on FPGA routing tracks is proposed. The principle idea is to superpose an induction voltage on the rising edge to lower its logic high toggling point while maintaining the falling edge intact. Thanks to the constant back induction voltage on the coupled transmission line, logic pulses can be stretched in a consistent manner.

The focus of this cross-talking TDC is to ameliorate the delay variations caused by temperature changes in conventional TDC designs. Theoretical analysis of temperature stabilities on pass-transistors, track buffers and metal wires is presented. Mathematical models are derived to compare their respective delay changes. Detailed calculations are performed using an α power law based transition delay model with device parameters extracted from both the 0.18µm TSMC process and the 22nm FinFET process according to previous articles. The impact of error accumulation on series connected transistor lines are emphasized, which is compared with the temperature response of an interconnect crosstalk, where only femtosecond scale impact is expected. Meanwhile, the resolution manipulation capability, the time synchronization design and a noise filtering circuit are discussed.

Experiments were conducted at different temperatures on commercial devices. During tests, the single shot precision, the effective resolution, and the non-linearity performance have all reached state-of-the-art. Noting that, 80fs resolution was observed. Most importantly, improvement on temperature stability is confirmed.
