Authors: Öztürk Fatmanur , Taşpınar Şener Zehra
Published: October 2024

The aim of this study is to reveal the suggestions of middle school mathematics teachers and preservice mathematics teachers that can both correct errors in students’ incorrect solutions and contribute to the advancement of students who have provided correct solutions. The study is based on the case study method. Initially, six problems related to proportional reasoning were posed to middle school students in a public school, and the solutions obtained from the students were classified according to their proportional reasoning strategies. These solutions were then examined by the students' mathematics teachers and by preservice mathematics teachers. Two questions were asked to mathematics teachers and preservice mathematics teachers during these examinations. After the examination, interviews were conducted to discuss the suggestions made to (1) correct the errors in incorrect solutions and (2) advance the proportional reasoning skills of students who obtained correct solutions. The findings indicate that both mathematics teachers and preservice mathematics teachers were adequate in providing suggestions to correct errors in students’ incorrect solutions. However, it was also found that both groups had difficulties in making suggestions to further the advancement of students who provided correct solutions.
The Ukraine in KRU (Kazakhstan, Russia and Ukraine): prospects for the Ukrainian grain economy (Ukraina w KRU (Kazachstan, Rosja i Ukraina): perspektywy ukraińskiej gospodarki zbożowej)
Authors: H. Meyers Wiliam , Goychuk Kateryna
Published: October 2024

Do czasu suszy, jaka nawiedziła Rosję w 2010 roku, udział eksportu zbóż z Kazachstanu, Rosji i Ukrainy (KRU) w światowym handlu zbożem wykazywał stały wzrost. W latach 2008/2009 oraz 2009/2010 kraje te razem eksportowały średnio 36,5 mln ton pszenicy rocznie, co stanowiło ponad 26% światowego eksportu pszenicy w tych dwóch latach. Była to ilość przewyższająca poziom eksportu każdego z pozostałych dużych dostawców pszenicy – USA, Kanady, UE-27 oraz Australii. Z uwagi na rosnącą rolę sektorów zbożowych w regionie KRU istotne jest dowiedzenie się czegoś więcej o roli Ukrainy w zachowaniach rynku globalnego. W niniejszej pracy koncentrujemy się na specyficznych cechach rolnictwa ukraińskiego, jego rosnącej integracji z rynkami światowymi oraz potencjalnej roli w przyszłych wydarzeniach na rynku zbożowym.
Szanse i zagrożenia rozwoju grup producentów rolnych
Authors: Kutkowska Barbara , Antosz Iwona
Published: October 2024

Łączenie się rolników w grupy producenckie jest koniecznością w sytuacji postępującego wzrostu konkurencji na rynkach rolnych. Dzięki integracji producenci mogą uzyskać ekonomiczne korzyści skali i ograniczać koszty wytwarzania produktów rolniczych. Po integracji Polski z UE proces zakładania nowych grup zdynamizował się. Impulsem była możliwość uzyskania dofinansowania z budżetu UE. Pomimo stale wzrastającej liczby grup producenckich, jest ich niewiele, zwłaszcza w relacji do liczby gospodarstw rolniczych w kraju. Na podstawie badań przeprowadzonych wśród członków i liderów grup producentów rolnych działających w woj. dolnośląskim dokonano próby zdefiniowania barier i możliwości rozwojowych tej formy współdziałania rolników. Rolnicy dostrzegają korzyści współpracy, głównie poprzez wspólne pokonywanie barier rynkowych, szansę widzą w dalszym finansowaniu z budżetu unijnego. Podstawową barierą są problemy mentalnościowe, a także słaba kondycja ekonomiczna gospodarstw, również zbyt małe zaangażowanie władz lokalnych w działalność grup oraz problemy administracyjne.

Drobne gospodarstwa w rolnictwie polskim. Próba definicji i charakterystyki
Authors: Dzun Włodzimierz
Published: October 2024

W artykule podjęto próbę zdefiniowania drobnych gospodarstw rolnych w polskim rolnictwie, określenia ich liczebności oraz dokonania charakterystyki pod kątem realizacji celów rolnictwa zrównoważonego. Przyjmując, że są to gospodarstwa bardzo małe obszarowo (do 5 ha) i bardzo małe ekonomicznie (do 4 SO), stwierdzono, że takich gospodarstw w polskim rolnictwie w 2010 roku było ponad 1,4 mln i stanowiły one 63% ogółu gospodarstw osób fizycznych. Liczba tych gospodarstw znacząco się zmniejsza, ale ich udział pozostaje wciąż bardzo duży. Analiza tej zbiorowości wykazała, że z punktu widzenia zrównoważonego rozwoju zdecydowana większość tych gospodarstw nie spełnia podstawowego wymogu, jakim jest wnoszenie, adekwatnego do posiadanego obszaru użytków rolnych i pozostałych środków produkcji, wkładu w zaspokojenie potrzeb żywnościowych społeczeństwa. W gospodarstwach tych widoczna jest tendencja do obniżania się i tak już niskiego poziomu produkcji roślinnej i wycofywania się z produkcji zwierzęcej. W rezultacie zapewniają one coraz mniej rzeczywistych miejsc pracy, a dochody z produkcji rolniczej w budżetach gospodarstw powiązanych z takimi gospodarstwami stanowią coraz mniejszy udział. Poza tym charakteryzują się one bardzo niskim poziomem środowiskowego zrównoważenia. Przede wszystkim nie realizują tak ważnego zadania, jakim jest utrzymanie potencjału produkcyjnego gleb. Analiza tych gospodarstw wyraźnie wskazuje na konieczność bardzo ostrożnego ich wspomagania ze strony państwa. Pomoc ta powinna się wiązać z jasno sprecyzowanymi obowiązkami produkcyjnymi i pozaprodukcyjnymi, i nie powinna hamować ewolucji gospodarstw rodzinnych w kierunku poprawy ich struktury obszarowej i produkcyjno-ekonomicznej.
Land policy in Ukraine and its impact on technical efficiency
Authors: Murowa Olga
Published: October 2024

This study investigates the impact of land policy on the technical efficiency (TE) of the Ukrainian crop sector for the year 2010. Two approaches are used to estimate TE scores: stochastic frontier analysis (SFA) and data envelopment analysis (DEA). Regions with high TE are examined in terms of land policies. Current analysis shows that overall, lease of land by all types of agricultural enterprises contributes to the increase of TE and lease of land by farming enterprises decreases efficiency. Comparison of current TE scores with TE scores estimated sixteen years ago shows differences in regional progress but the overall increase of TE in Ukraine.

Authors: Podgórski Bogdan , Świętochowski Leszek
Published: October 2024

W artykule podjęto próbę przedstawienia dotychczasowych działań ANR w zakresie realizacji zadań ustawowych, w tym problematyki rozdysponowania nieruchomości. Od początku działalności ANR trwale rozdzieliła 2,9 mln ha, w tym 2,3 mln ha poprzez sprzedaż, która jest dominującą formą rozdysponowania. Przedmiotem tego typu działalności jest również infrastruktura przejęta wraz z majątkiem PGR, w tym mieszkania byłych pracowników. Pozostające 1,8 mln ha podlega dalszym procesom prywatyzacji. Dzierżawa gruntów zmniejsza się co roku o ponad 100 tys. ha w wyniku rozwiązywania umów dzierżawy i wyłączania z nich części gruntów. Analizę przeprowadzono na podstawie danych pochodzących głównie z raportów z działalności Agencji Nieruchomości Rolnych, opracowań wewnętrznych i dostępnej literatury przedmiotu. Zaprezentowane wyniki świadczą o dużym zaangażowaniu ANR w prywatyzację oraz wielu złożonych procesach, które towarzyszą trwałemu rozdysponowaniu nieruchomości po 20 latach jej funkcjonowania.

Desigualdades en calidad de vida de los adultos mayores bolivianos. La educación un factor clave
Authors: Coa Clemente Ramiro , Loza Cruz Patricia
Published: October 2024

Esta investigación tiene como objetivo analizar las desigualdades en calidad de vida de los adultos mayores bolivianos a partir de un índice de calidad de vida. Con base en un conjunto de indicadores generados con datos de la encuesta de hogares realizada por el Instituto Nacional de Estadística en el año 2021, indicadores enmarcados en la propuesta teórica-metodológica del Centro Latinoamericano y Caribeño de Demografía, y con el uso de la técnica de componentes principales, se construyó un índice de calidad de vida en la vejez. El índice refleja notables desigualdades en calidad de vida de los adultos mayores. La calidad de vida para el quintil superior es más del doble que para el quintil inferior, disminuye a medida que incrementa su edad, aumenta cuando incrementa su ingreso y sube notablemente cuando aumenta la educación del adulto mayor. El análisis causal revela que la educación del adulto mayor lograda cuando era relativamente joven tiene un impacto muy importante para la calidad de vida en su vejez, mucho más que el de su ingreso, por lo que mayor nivel de educación viabiliza mejor calidad de vida en la vejez. Se recomienda que las políticas y programas orientadas a mejorar la calidad de vida en la vejez deban tomar en cuenta estas desigualdades y que en futuros estudios sobre el tema se obtenga información sobre autopercepción de la calidad de vida.

Bovinos para carne: ¿realmente los queremos tan dóciles?
Authors: Gonzalez Ana Clara , Ferrari Héctor Ricardo
Published: October 2024

En la ganadería de carne, los bovinos muy temerosos o agresivos son indeseables y, en consecuencia, rechazados sobre todo por cuestiones productivas y de seguridad laboral. Aparentemente, está instaurado el supuesto de que cuanto más dócil, mejor es el animal. El presente artículo pone en tela de juicio el hecho de contar con ganado extremadamente dócil en cualquier contexto productivo y ofrece una mirada crítica en torno al temperamento como atributo funcional al sistema de producción de tipo pastoril. En condiciones agroecológicas semejantes al ambiente ancestral de la especie, el fenotipo intermedio en docilidad contribuiría a una mayor aptitud biológica. Asimismo, se invoca al bienestar animal como criterio a contemplar en el mejoramiento genético.

Authors: Benitez Ralph Andrei A. , Acula Donata D. , Bondoc Anton Oliver M. , Hizon Angelo Louis L. , Santos Aaron Joseph D.
Published: October 2024

Misinterpreted medical prescriptions had led to casualties due to the illegible cursive handwriting of medical practitioners. Many studies focused on this problem. However, the accuracy was unsatisfactory and needed improvement. The study evaluated the performance of the Canny edge detection with other preprocessing methods, including RGB to Grayscale Conversion, Binarization, and Inversion, which was used to process the images of cursive handwritten medical prescriptions using Alexnet Convolutional Recurrent Neural Network (ACoRNN). The CRNN model developed by previous researchers was used as the basis for comparison, and the researchers created a faster and more accurate model. The best combination of preprocessing methods for ACoRNN was with RGB to Grayscale Conversion, Binarization, Canny edge detection, and Inversion. The researchers’ model had faster preprocessing and testing time and achieved 90.76% average accuracy through five trials.

Given the current rate of urbanization, municipalities in most Nigerian cities have struggled with the collection, transportation, and disposal of solid waste. This is due to waste generation, both residential and commercial, occurring in a dispersed manner across homes, buildings, streets, parks, and even vacant spaces within communities. This manuscript aims to evaluate the state of municipal solid waste management in Ibadan, household solid waste storage practices, and the locations of solid waste storage containers (skip points) in relation to accessibility and health risks to the community, in accordance with Nigerian National Solid Waste Management Standards and other pertinent international standards. A structured questionnaire was distributed to 21 micro and small firms and 250 homes in each of the three local government areas of the metropolis, with descriptive statistics used to interpret the data. According to the study results, inadequate Municipal Solid Waste Management (MSWM) service delivery in the Ibadan metropolitan area can be attributed to several issues, including a lack of institutional coordination among urban planners. The study’s conclusions indicate that the state of MSWM in the sampled areas is either inadequate or has poor spatial coverage and container utilization. Lastly, the study primarily suggests that these measures can reduce problems associated with MSWM by encouraging public-private partnerships, fostering effective institutional coordination with urban planner consultants in MSWM and skip-point location, and motivating the community to adopt integrated sustainable Solid Waste Management (SWM) strategies.

Environmental Impact and Decompsition of Polycyclic Aromatic Hydrocarbons (PAHs) in Urban Soils: Challenges and Future Directions
Authors: Emre Mehmet , Rubiyatno  , Tongco Jovale Vincent , Permana Rega
Published: October 2024

The rapid pace of urbanization and development has led to an increasing global concern over polycyclic aromatic hydrocarbons (PAHs) due to their persistent and widespread presence in the environment, posing significant threats to ecosystems and human health. PAHs originate from both natural and human-made sources and can be categorized based on their origin into pyrogenic, petrogenic, and biogenic products. Upon entering the environment, PAHs undergo various chemical and biological transformations, and their movement occurs through processes such as air-to-soil and soil-to-air transport. Composting, a green and cost-effective technology, offers a promising solution for PAH remediation. This process, which includes mesophilic, thermophilic, cooling, and maturing stages, can yield compost that is useful as fertilizer and soil amendment in agriculture. The success of composting depends on factors such as substrate bioavailability, oxygen levels, nutrient supply, and environmental conditions. While composting has shown effectiveness in reducing PAH levels, it is not without challenges, including the risk of weed infestation, greenhouse gas emissions, and odor pollution. The main obstacles in PAH remediation today are the limited bioaccessibility of PAHs and the insufficient focus on the formation of oxygenated PAHs during the process. Future research should address these challenges, particularly by improving PAH bioaccessibility and mitigating issues related to odor and greenhouse gas emissions.

Authors: Necira Abdelouahab , Salhi Souheil , Salhi Ahmed , Naimi Djemai , Abujarad Saleh
Published: October 2024

The optimal reactive power dispatch (ORPD) challenge is crucial for ensuring the efficient and reliable operation of power systems, hinging on the effective coordination of multiple devices.As a result, solving the ORPD problem involves tackling a complex nonlinear optimization challenge that demands advanced computational algorithms to determine the optimal solution. This article introduces an enhanced version of the modified algorithm, called L-E-SSA, which is inspired by the coordinated movement of a swarm led by a single member (salp swarm algorithm SSA), incorporating Levy Flight elitism, to effectively solve the ORPD problem. This study aims to reduce power losses (Ploss) and total voltage deviation (TVD) by optimizing the control variables. Numerical simulations are carried out on IEEE (30-bus)  and IEEE (118-bus)  power systems. To evaluate the performance and effectiveness of the modified algorithm (L-E-SSA). The results indicate that the L-E-SSA algorithm delivered strong performance and secured a competitive ranking through statistical analysis. Simulations demonstrate that the proposed method has the potential to be a highly effective solution for the ORPD problem.
Optimal control design for power system stabilizer using a novel crow search algorithm dynamic approach
Authors: Salhi Souheil , Necira Abdelouahab , Salhi Ahmed , Benkhetta Djemoui , Naimi Djemai
Published: October 2024

This paper proposes the first application of a novel improved metaheuristic optimization technique, dynamic crow search algorithm (DCSA) to find the optimal design of the power system stabilizer (PSS). Using the novel DCSA adaptive approach provides a global search capability as well as fastness and effectiveness to get the PSS best parameters under the search space constraints and local optimums. Moreover, PSS parameters has a crucial effect on power system stability that is a major nowadays engineering concern, where its best parameters could make a difference by damping small-signal stability oscillations effectively and in the smallest amount of time if they are obtained through a robust algorithm. As a result, PSS will prevent large types of instabilities which could reach up to some generation stations shedding.  The novel proposed algorithm is for first time used and tested under different power system instabilities scenarios by using single-machine infinity bus model over multiple operating conditions to damp out perturbation signals effectively by means of getting optimal PSS design parameters, where Integral absolute error (IAE) performance index is used as an objective function to be minimized. Additionally, results obtained by the proposed approach are compared with those obtained by other methods. It is observed that the proposed method has better convergence characteristics and robustness compared to the original version and other comparison methods. It is revealed that the proposed adaptive method is able to improve the power system stability dynamics and damp out perturbation oscillations successfully.

Estamos cientes de que há um grande abismo entre as ideias e a realidade, especialmente no campo da educação, onde teorias muitas vezes se chocam com a prática cotidiana das escolas e das políticas públicas. Reconhecendo essa distância, buscamos, por meio de uma pesquisa bibliográfica (Gil, 1999) e qualitativa (Minayo, 2016), mas principalmente de caráter compreensivo (Weber, 2019), analisar as contribuições de Paulo Freire como educador e gestor. A proposta é ir além de suas teorias pedagógicas e explorar como suas ideias, forjadas no campo da educação popular, foram colocadas em prática quando Freire assumiu o cargo de Secretário de Educação da cidade de São Paulo, entre os anos de 1989 e 1991. Durante esse período, Freire foi desafiado a adaptar suas concepções libertadoras de educação a um contexto institucional e burocrático, onde o impacto de suas ideias foram limitadas pelas estruturas de poder vigentes. Assim, o foco deste estudo é investigar de que forma ele conseguiu traduzir suas reflexões teóricas em ações práticas dentro de uma grande rede pública de ensino, e quais foram os resultados dessas intervenções no âmbito das escolas populares não apenas no Brasil, mas também em outras partes da América Latina. Diante disso, formulamos a seguinte indagação: Como a atuação de Paulo Freire como Secretário de Educação da cidade de São Paulo, entre 1989 e 1991, transformou suas ideias educacionais em práticas de gestão que impactaram as escolas públicas populares na América Latina? Teoricamente, utilizamos os trabalhos de Gadotti (2000), Lima (2002) e Antunéz (2008). Desse modo, realizamos uma análise comparativa, confrontando o discurso freiriano com suas realizações administrativas. Nesse processo, destacamos os sensos e dissensos que emergiram de sua gestão: sensos, no sentido de consenso e adesão às suas propostas por parte de alguns setores educacionais, e dissensos, no que se refere às resistências enfrentadas e aos desafios impostos por uma estrutura educacional já estabelecida. Freire, um defensor da educação como prática da liberdade, encontrou um ambiente no qual precisou negociar seus ideais, adaptar-se à realidade e lidar com as tensões entre a inovação pedagógica e os limites da política institucional.

The effects of weather alteration are generally cited as one of the most significant challenges facing conservation efforts. Recent research indicates that it is feasible to identify the consequences of a changing climate on biological systems. Environment change is a worldwide problem that requires quick attention. The topic of environmental change and how to adapt to it has been the topic of several studies. More efficient and effective variation and extenuation measures are needed, but only if new approaches are developed to investigate the intricacies of environmental change. In recent years, Deep Learning (DL) approaches have become more popular across a variety of industries, environmental change included. It is to examine the most widely used DL techniques for combating and familiarising to environmental change. The second goal is to classify the greatest widely-studied mitigation and adaptation measures across all locations, but especially in urban regions using DL techniques. According to the results, the most widely used DL approach is also the most effective in mitigating and adapting to environmental changes. Furthermore, geo-engineering and land surface temperature studies have employed DL algorithms more than any others in the field of environment change mitigation and reworking. The weather, including its temperature, humidity, clouds, and wind speed, are all potential contributors. This work analyses the major impacts of the local environment and climate on these characteristics. The study uses Indian state Haryana's local weather data (from January 1, 2012, to December 31, 2022). In the result, shows that this section’s highest winds speed are around 9 Km/h in the month of June.

Published: October 2024

We introduce data structures and algorithms to count numerical inaccuracies arising from usage of floating numbers described in IEEE 754. Here we describe how to estimate precision for some collection of functions most commonly used for array manipulations and training of neural networks. For highly optimized functions like matrix multiplication, we provide a fast estimation of precision and some hint how the estimation can be strengthened.

Prevalence of Keratoconus and Keratoconus Suspect among a sample of Iraqi Children with Refractive Errors: A Cross-Sectional Study
Authors: Rashak Aseel Sabr , Abdulateef Nadia Abdulazeez , Abdulkareem Suzan
Published: October 2024

Background: Keratoconus (KC) is a chronic, bilateral, non-inflammatory degenerative condition with severe consequences. Objective: To assess the prevalence of KC and Keratoconus Suspect (KCS) in a pediatric population with astigmatic error ≥1 diopter (D) and non-axial myopia. Methods: Between March and October 2022, a cross-sectional study was done with a group of 6–18-year-old kids with an astigmatic error of ≥1 D or non-axial myopia who went to the pediatric ophthalmology clinic at Ibn Al-Haitham Teaching Eye Hospital in Baghdad, Iraq, for regular checkups. All patients got a thorough eye examination and corneal imaging using the Corneal Tomography System (CSO) Sirius equipment and Scheimpflug technology. Results: The majority of patients were females aged 110–14 years (55%). The frequencies of KC and SKC were 13.5 and 119.6%, respectively. The proportion of KC was substantially higher for those above the age of 14. Patients with KC exhibited considerably larger cylinder and axis measurements. Participants with inferior cones and an asymmetric Bow Tie exhibited greater rates of KC (51.2% and 29.4%, respectively). Except for Pachy-Thin and corneal volume mean values, all other metrics were considerably greater in KC and KCS patients than in control patients. Conclusions: The high prevalence of KC and KCS emphasizes the importance of this issue and the necessity for a systematic strategy for screening in pediatric age groups with refractive error.
Elements of Higher Mathematics: Learning Mathematics through Numbers
Authors: Keune Frans
Published: October 2024

This is a textbook for beginning mathematics students. Knowledge of school mathematics is not presumed: it starts with the basics of counting. The underlying idea is that the best way to learn mathematics is by doing mathematics. For beginning students it is sometimes a problem to assume when looking for proof. For the exercises in this textbook, this situation does not occur: except for the introductory part all is built on Peano's axioms for the natural numbers, using the language of set theory only. The book starts explaining the way mathematics works: the use of intuitive set theory and the relation between language and mathematical entities. The common thread in the book is the construction of the number system all the way from the natural numbers, via the rationals and the reals to the complex numbers. For the student, the advantages of this approach are: One learns concepts which are fundamental for all of mathematics. The common thread offers a natural way for the introduction of these concepts. It helps to stay motivated during the course. One learns to think like a mathematician. One obtains insight into the way mathematics is built from simple ideas. It helps to decide whether one is fitted for a mathematics study. For the interested reader also the other possible completions of the rationals - the p-adic numbers - are constructed. The book contains more than just the construction of the number system: there is also attention for its use, especially in combinatorics, number theory and cryptography, leaving mathematical analysis to the many textbooks for analysis and calculus courses.
Dinanath grass (Pennisetum pedicellatum L.) in association with six popular tree species of western Orissa
Authors: Mohapatra Subash
Published: October 2024

An experiment on silvipastoral system was conducted for three consecutive years (1996 to 1998) in slightly slopy, red lateritic culturable wasteland. Six popular tree species (viz. Eucalyptus tereticornis, Acacia auriculiformis, Acacia nilotica, Dalbergia sissoo, Samanea saman, and Albizia lebbeck) differed significantly on growth of plant height (PH), and Girth at shoulder height (GSH). Eucalyptus tereticornis showed maximum growth of PH and GSH followed by Acacia auriculiformis. Fodder yield of Dinanath grass in two cuts was highest under the tree canopy of Dalbergia sissoo followed by Samanea saman and lowest in the interspaces of Eucalyptus tereticornis.

Authors: Liu Jiaqi , Zhang Yincheng , Qian Weiyu
Published: October 2024

Abstract. Our study try to address the challenge of accurately identifying depression and suicidal ideation on social media platforms by introducing an enhanced novel methodology for unsupervised feature selection and label correction. Utilizing advanced word embedding models like BERT and the Universal Sentence Encoder, we transform textual content into dense numerical vectors that capture the nuanced emotional context of online discussions. Our approach enhances these embeddings with a deep neural network (DNN) to extract distinctive features, reducing the dimensionality of the data through Principal Component Analysis (PCA). For label correction, we employ clustering techniques including OPTICS, K-medoids, and hierarchical clustering, which are robust against noisy data points. We then train classifiers using CNN, DNN, logistic regression, and random forest algorithms, evaluated with metrics such as accuracy, precision, recall, F1 score, and AUC. This methodology improves the accuracy of classifying depressive and suicidal sentiments to some extent, assisting to utilize the vast data available on social media to advance mental health diagnostics and interventions.
