A inclusão não se restringe apenas ao contexto escolar, é uma questão que abrange o âmbito político e social. O presente trabalho investigou como professores de Ciências Naturais da rede pública do único colégio de um município do extremo sul da Bahia trabalhavam os conteúdos biológicos para alunos com deficiência. A pesquisa tem abordagem qualitativa e utilizou como instrumento de coleta de dados o questionário misto, aplicado a sete professores de Ciências que se encaixavam nos critérios de inclusão do estudo A metodologia de análise de dados utilizada foi a análise de conteúdo. Foi possível analisar as relações entre as concepções de educação inclusiva e as atividades e metodologias adotadas pelos docentes pesquisados. A maioria dos participantes da pesquisa afirmou ter tido discussões sobre inclusão ao longo de sua formação inicial e continuada. No entanto, evidenciaram que ainda há muita dificuldade, especialmente no que se refere às especificidades relacionadas ao ensino de Ciências. Para os docentes pesquisados, trabalhar temáticas envolvendo a inclusão é necessário, pois a teoria articulada à prática possibilita reestruturar as ações pedagógicas. Assim, é possível observar que há lacunas relacionadas ao ensino inclusivo que precisam ser superadas. Para tanto, são necessárias a ampliação das discussões e outras pesquisas nesse âmbito.

Abstract Inclusion is not restricted to the school context, it is an issue that covers the political and social scope. The present work investigated how teachers of Natural Sciences from the public network of the only school in a city in the extreme south of Bahia worked with the biological content with students with disabilities. The research has a qualitative approach and used as a data collection instrument the mixed questionnaire, applied to seven Science teachers who fit the inclusion criteria of the study. The data analysis methodology used was content analysis. It was possible to analyze the relationships between the concepts of inclusive education and the activities and methodologies adopted by the surveyed teachers. Most research participants stated that they had discussions about inclusion throughout their initial and continuing training. However, they showed that there is still a lot of difficulty, especially with regard to the specificities related to Science teaching. For the teachers surveyed, working on themes involving inclusion is necessary, as theory articulated with practice makes it possible to restructure pedagogical actions. Thus, it is possible to observe that there are gaps related to inclusive education that need to be overcome. Therefore, it is necessary to expand discussions and other research in this scope.

Wheat in the world and in Turkey to be essential nutrients to maintain the leading status in the still, as a result, it is widely cultivated. Therefore, it is important to increase the genetic and physiological diversity in wheat. Mutation breeding is an effective method for increasing genetic diversity in cultivated plants. The aim of this study is the identification of different duration [control (10 min), 1 h, 2 h and 3 h] effects and concentrations [0 (control), 0.5, 1, 1.5 and 2 mM] of sodium azide (NaN3) mutagen in germination and seedling growth on wheat (Kırik cultivar) and determine the optimum doses of sodium azit which can be used in breeding programs. This study was conducted in 4 replicates according to the completely randomized factorial design. Some germination and seedling characters were investigated in this study. The results showed that except the germination percentage application of sodium azide in different concentrations and duration were significantly affected all considering traits. We believe that increase concentration and duration treatment of SA leads to decreases germination rate index and germination vigor index despite that means time to germination also was increased. Likewise, seedling growth characters significantly were affected by NaN3 application concentration and duration. Also based on the value of LD50 2 h treatment + 1 mM concentration was determined for the optimum dose of the applied root and shoot length.

Scrophularia fatmae Kandemir & İlhan and Scrophularia erzincanica R.R. Mill (Scrophulariaceae) are endemic species to Erzincan/ Turkiye. IUCN categories in S. erzincanica and S. fatmae are EN and CR. In the present study, we investigated levels of genetic variation and genetic structure of three populations of S. erzincanica, and two populations of S. fatmae in Erzincan using ISSR markers. For this aim, 10 primers amplified 116 total bands, with 104 (89.6 %) being polymorphic, from five populations composed of 75 individuals. The UPGMA cluster analysis demonstrated a significant correlation between genetic variations and geographic distances. The distribution area and population size of S. fatmae, which has adapted to the alpine region, is smaller. In addition, S. fatmae has a higher tendency to self-pollination. S. erzincanica has a larger population. The number of effective pollinators in S. erzincanica and S. fatmae are three and one, respectively. With the contribution of these reasons, when we compare S. fatmae and S. erzincanica species according to the results of the research, it is seen that genetic diversity is higher in S. erzincanica. The genetic data obtained as a result of present study may be used in the development of conservation strategies for other rare and endangered plant species, in addition to S. erzincanica and S. fatmae species.

AIM: To evaluate the clinical application value of the artificial intelligence assisted pathologic myopia (PM-AI) diagnosis model based on deep learning.
METHODS: A total of 1156 readable color fundus photographs were collected and annotated based on the diagnostic criteria of Meta-pathologic myopia (PM) (2015). The PM-AI system and four eye doctors (retinal specialists 1 and 2, and ophthalmologists 1 and 2) independently evaluated the color fundus photographs to determine whether they were indicative of PM or not and the presence of myopic choroidal neovascularization (mCNV). The performance of identification for PM and mCNV by the PM-AI system and the eye doctors was compared and evaluated via the relevant statistical analysis.
RESULTS: For PM identification, the sensitivity of the PM-AI system was 98.17%, which was comparable to specialist 1 (P=0.307), but was higher than specialist 2 and ophthalmologists 1 and 2 (P<0.001). The specificity of the PM-AI system was 93.06%, which was lower than specialists 1 and 2, but was higher than ophthalmologists 1 and 2. The PM-AI system showed the Kappa value of 0.904, while the Kappa values of specialists 1, 2 and ophthalmologists 1, 2 were 0.968, 0.916, 0.772 and 0.730, respectively. For mCNV identification, the AI system showed the sensitivity of 84.06%, which was comparable to specialists 1, 2 and ophthalmologist 2 (P>0.05), and was higher than ophthalmologist 1. The specificity of the PM-AI system was 95.31%, which was lower than specialists 1 and 2, but higher than ophthalmologists 1 and 2. The PM-AI system gave the Kappa value of 0.624, while the Kappa values of specialists 1, 2 and ophthalmologists 1 and 2 were 0.864, 0.732, 0.304 and 0.238, respectively.
CONCLUSION: In comparison to the senior ophthalmologists, the PM-AI system based on deep learning exhibits excellent performance in PM and mCNV identification. The effectiveness of PM-AI system is an auxiliary diagnosis tool for clinical screening of PM and mCNV.

AIM: To determine the one-year outcomes of resveratrol oral supplement in patients suffering from wet age-related macular degeneration (AMD).
METHODS: Fifty naïve and previously untreated patients suffering from wet AMD, were randomly assigned in two subgroups of 25 patients each. All the participants were treated with 3 monthly intravitreal injections of 2.0 mg aflibercept (IAIs) followed by injections “according to need”, while in one group the patients also received daily two tablets of resveratrol oral supplement. Prior to treatment initiation, a complete ophthalmological examination, including best corrected visual acuity (BCVA) and contrast sensitivity evaluation, optical coherence tomography (OCT) scans, fundus autofluorescence (FAF), fluorescein angiography, indocyanine green angiography, and OCT angiography (OCTA), was performed to every participant, while all of them completed the Hospital Anxiety and Depression Scale (HADS) questionnaire, in order to assess their quality of life (QoL) status. The patients were assessed monthly for 1y with FAF, and OCT or OCTA; the main endpoints were the number IAIs, the changes in BCVA, in contrast sensitivity, and in patients' QoL status.
RESULTS: No significant differences were present between the groups regarding the baseline demographic and clinical data. Over the 12-month period, a similar number of IAIs was applied in both groups (4.52±1.00 vs 4.28±0.90, P=0.38), while the rest of the clinical data also did not differ significantly after the completion of the study period. However, for HADS Depression (11.88±2.51 vs 8.28±1.54, P<0.001) and HADS Anxiety (11.92±2.52 vs 7.76±1.51, P<0.001) questionnaires values, the score was significantly better in patients who received resveratrol supplements. Moreover, a statistically significant difference was detected in the mean change from baseline values of contrast sensitivity (0.17±0.19 vs 0.35±0.24, P=0.005), HADS Depression (0.08±1.38 vs -3.88±1.48, P<0.001), and HADS Anxiety (0.36±1.98 vs -5.12±2.70, P<0.001) scores, in favour of the patients treated with resveratrol supplements.
CONCLUSION: The resveratrol oral supplement is a complementary treatment in cases of wet AMD, highlighting its effectiveness in improving patients' QoL status.

AIM: To explore the effect of orthokeratology (OK) fitting on retinal vessel density in low to moderate myopia adolescents by using optical coherence tomography angiography.
METHODS: Children aged 10 to 14y with a cycloplegic spherical equivalent refraction of −0.50 diopter (D) to −5.00 D and astigmatism with more than −1.50 D were recruited. The enrolled adolescents were divided into OK group and spectacle group. During regular follow-up, adolescents were measured respectively at pre-wear, 1, 3, and 6mo after treatment. The follow-up included uncorrected distance visual acuity (UDVA), axial length (AL), superficial capillary plexus density (SCPD), deep capillary plexus density (DCPD), central retinal thickness (CRT), foveal avascular zone area (FAZ-A), foveal avascular zone perimeter (FAZ-P) and foveal vessel density in a 300-µm-wide region around foveal avascular zone (FD-300). The collected data were analyzed using statistical methods.
RESULTS: By one month, SCPD significantly increased in the fovea and superior retina, and DCPD significantly increased inferiorly in OK group compared to spectacle group (P<0.05). By three months, there were significant increases in SCPD in the fovea and inferior retina, and DCPD in the parafovea, superior, and inferior retina in OK group (P<0.05), while the increase in SCPD and DCPD in the fovea were observed by six months (P<0.05). The FD-300 significantly increased at every follow-up in OK group compared to spectacle group (P<0.05). No significant differences in the CRT, FAZ-A and FAZ-P and FD-300 were observed between two groups (P>0.05). OK group showed a significant improvement in UDVA after wearing OK, compared to spectacle group (P<0.01), while the AL did not show a significant difference between two groups (P>0.05).
CONCLUSION: Short-term OK worn can increase local retinal vessel density in adolescents with low-to-moderate myopia.

Published: August 2023

AIM: To investigate the prevalence of color vision deficiency (CVD) among college students and their quality of life (QoL) in a Chinese college.
METHODS: This cross-sectional study was performed in Sichuan University in Chengdu, China. The questionnaire containing participants' demographic data, as well as CVD related QoL was distributed to students who were screened as CVD [by Color Vision Examination Plates (Version 6)] in 2022 freshman entrance examination. Color blindness QoL (CBQoL) and utility analysis were used to evaluate the QoL of CVD students.
RESULTS: There were 381 of 17 303 (2.20%) students screened as CVD, including 368 (4.11%) males and 13 (0.16%) females. A total of 317 students completed the questionnaire, the response rate was 83.20%. Only 166 participants (52.3%) knew they have CVD before the physical examination for college entrance examination, while a total of 145 participants (45.74%) hoped to be diagnosed earlier. The medians of CBQoL score and utility were 5.85 (range 2.2-6) and 1 (range 0-1), respectively. The proportions of students whose QoL is affected by CVD were 67.63% (211/312) and 42.27% (134/317) measured by CBQoL and utility analysis respectively.
CONCLUSION: The prevalence of CVD in males is much higher than that in females. The time when CVD students first became aware of their CVD is relatively late. The QoL of the study population is quite high, while a large proportion of students' QoL are affected by CVD. It is suggested that as a congenital defect, CVD screening in China should be earlier, and appropriate guidance and support are needed for CVD patients to help them better adapt to life, study, and work.

Redystrybucja dochodów w świecie nierówności
Authors: Krajewska Anna , Krajewski Piotr , Piłat Katarzyna
Published: August 2023

Przez wiele lat w dyskusjach nad przemianami w polskiej gospodarce skupiano się przede wszystkim na wzroście gospodarczym a relatywnie mało uwagi przywiązywano do rosnącego zróżnicowania dochodów. Wzrost zainteresowania w światowej literaturze problemem nierówności oraz zwiększenie zróżnicowania dochodów w Polsce skłaniają jednak do zwrócenia uwagi na sposoby przeciwdziałania temu zjawisku na tle doświadczeń innych krajów Unii Europejskiej. Z tego względu w monografii dokonano analizy nierówności dochodowych w Unii Europejskiej, ze szczególnym uwzględnieniem gospodarki polskiej, a także ukazano mechanizmy, poprzez które redystrybucja wpływa na obniżenie nierówności dochodowych we współczesnych gospodarkach. Z przeprowadzonych w monografii analiz wynika, że redystrybucja dochodów odbywająca się poprzez kształtowanie podatków i wydatków publicznych może stanowić skuteczne narzędzie niwelowania nierówności dochodowych w krajach Unii Europejskiej. Na podstawie dokonanych porównań międzynarodowych zaobserwować przy tym można, że instrumenty te w niejednakowym stopniu wykorzystywane były w różnych modelach polityki społecznej. W szczególności, przeprowadzone analizy wskazują, że podatki w niewystarczającym stopniu oddziałują na redystrybucję dochodów w Polsce. W celu skuteczniejszego niwelowania nierówności dochodowych w gospodarce polskiej wskazana jest zatem znaczna reforma systemu podatkowego, obejmująca m.in. wzrost udziału wpływów z podatków dochodowych i majątkowych w dochodach budżetowych, czy ujednolicenie zasad dotyczących stosowania progresji w ramach opodatkowania dochodów.
Characterizing the risk and impacts of tropical cyclones on banana production in the Philippines
Authors:   Instituto de Ecología y Biodiversidad: CL, Ortiz Andrea Monica ,   Manila Observatory: Quezon City, PH
Published: August 2023

The Philippines is one of the world’s largest producers of banana. The Philippines is also vulnerable to climate change and tropical cyclones (TCs), which caused over 236 billion Philippine Pesos worth of losses and damages to agriculture between 1990-2013. TCs can have impacts on banana, which is sensitive to strong winds and flooding. However, banana remains under-studied in the context of food security, climate change, and variability. Here, the physical risk of banana production to TCs by characterizing the hazard, exposure, and physical sensitivity of suitable cropland to TCs. Data on TCs, banana production and prices, and the costs of damages from TCs were also analyzed to provide a picture of TC impacts. The analysis shows that there are different levels of risk to cropland from TCs, and it is higher in Luzon and Eastern Visayas which are exposed to more, and more intense TCs. Mindanao currently has a low calculated physical risk to TCs, although because of the concentration of banana production in Central and Southeastern Mindanao, there may be more exposed, and thus vulnerable, cropland. Linear statistical relationships are poor between banana production and TCs, although recent experience from Typhoons Pablo and Odette (TC Bopha and Rai, 2012 and 2021) give evidence to the significant losses and damages from TC on banana production in Mindanao. Because TCs are projected to potentially become more intense, with more variability and uncertainty from climate change, more research is needed, given the banana’s importance in the Philippines.
El problemático lugar de la animalidad en la filosofía de Ortega
Authors: Alonso Marcos
Published: August 2023

El presente artículo aborda un problema de gran actualidad en la filosofía contemporánea: la comprensión del ser animal y sus relaciones con el ser humano. En concreto, se analizará el tratamiento de esta cuestión por parte del filósofo español Ortega y Gasset, uno de los primeros autores en convertir este asunto en un tema específico y recurrente de su reflexión. Se mostrará cómo la filosofía de Ortega arriba a este problema, qué influjos intelectuales marcan su aproximación al animal, y qué lugar ocupa en el contexto de su propuesta filosófica. Concluiremos que, al igual que gran parte de los autores más relevantes del siglo XX, el pensamiento de Ortega está enormemente marcado por sus consideraciones sobre el animal; y que estas ideas todavía pueden ser provechosas a la hora de estudiar estos importantes problemas relacionados con el estatuto y significación de la condición animal.
Propiedades y antecedentes gnoseológicos del gnosticismo moderno y contemporáneo. Un análisis crítico desde el pensamiento de Eric Voegelin
Authors: Buzeta Undurraga Sebastián
Published: August 2023

La presencia gnóstica denunciada por Voegelin a finales del siglo pasado y que ha visto su expresión más fiel en las ideologías contemporáneas, ha ido mutando a diversas manifestaciones denunciadas por teóricos contemporáneos, no solo por su naturaleza inmanente, sino por su misma inconsistencia gnoseológica. Así, el presente artículo tiene por objeto profundizar en torno a las propiedades o características fundamentales del gnosticismo moderno y contemporáneo, así como en sus antecedentes gnoseológicos. Para llevar a cabo esta labor nos centraremos en un análisis crítico, primero en las características del pensamiento gnóstico, fundamentalmente a partir de las ideas de Voegelin, para luego analizar sus antecedentes ubicados en el pensamiento teológico de Joaquín de Fiore y del nominalismo de Guillermo de Occam.

The paper is devoted to the study of formation of the amplitude-frequency spectrum of the current of the contact network feeders during the transition process. On the basis of the field measurements carried out at the AC operating traction substations of the Far Eastern Railway, the analysis of the harmonic components of the current was performed. Full-scale measurements were carried out by a measuring and computing complex having a discrete Fourier transform function in its software. The study of changes in the amplitudes of the harmonic components of the current and their increments at short time intervals was carried out, on the basis of which their numerical characteristics are calculated. The distinctive features of formation of harmonic current spectra in the short-circuit mode and with a sharp increase in the load of the traction network are revealed. It is proposed to use the identified features of the harmonic composition of the current as an identifier of emergency and normal modes of operation of the traction network, which will improve its protection in the future.

The article proposes an approach to the analysis of the strategy of «Russian Railways» holding to attract and increase the interest of customers of transport services based on a model of game theory, namely, a hierarchical bimatric game. Here the holding company acts as the first player, cargo owners - the second one. It is proposed to model the behavior (strategies) of consumers taking into account their differentiation. The statistical analysis of cargo owners based on up-to-date data, forecast and comparative analysis of the potential response of consumers to possible decisions of the holding on implementation of strategies were conducted. It is shown that the significant development of transport and logistics services is the most preferable strategy, since it allows differentiating the company’s business lines and obtaining the additional source of income without significant increase in traffic volumes.

Or positive results in reducing the number of failures of electric traction engines, predictive diagnostics in operation is proposed. The development of malfunctions in electric traction engines directly affects the registration of analog signal values by on-board equipment. Some distinctive criteria have been identified by which the technical condition of electric traction engines can be assessed. The previously developed algorithm for searching for electrical damage has been improved. The presence of a difference in armature current between adjacent bogies and pairs of the same type of electric traction engines is pointed out, the dependence between a serviceable and faulty electric traction engine in the form of discrepancy in correlation coefficients is revealed. All the revealed conditions are added to the algorithm for determining the technical condition, the processes of which are built on the KNIME intelligent analysis platform. The process of determining the technical condition with the output of the result on the serviceability / malfunction of the electric traction engine is modeled. A pair of electric traction motors with a potential malfunction is also identified. The relative modeling error, which is at an average level, allows us to partially solve the problem of occurrence of failures of electric traction engines during operation. The application of the model along with the existing methods improves the quality of predictive diagnostics of modern locomotive equipment.

This paper is devoted to analytical methods for solving shallow water equations which simulate water flows when a tsunami comes ashore in the two-dimensional case. The currents are considered near the edge boundary, which for the two-dimensional model is the point of intersection of the water surface with the shore. In order to do this, the system of equations is rewritten in a polar coordinate system with a center at the corner point of the edge boundary. Then the independent variable and unknown function switch roles. An alternative is proved for the resulting system: the motion of the edge boundary is determined from the solutions of a nonlinear system of partial differential equations, or at the edge boundary the derivative of an unknown function is equal to infinity. In order to construct a solution, a power series is compiled, the coefficients of which are solutions of ordinary differential equations. The existence and uniqueness theorem of a solution constructed as a series with analytical boundary conditions is substantiated.

As part of the work, the technical condition of innovative gondola rail cars built in 2015-2021 was analyzed in comparison with gondola rail cars on trolleys with the axial load of 23.5 t/axle. When evaluating the railway car efficiency, the number of railway car uncouplings in the current and planned types of repairs during the overhaul period was taken as a basis. It is shown that a significant proportion of gondola rail cars uncouplings in the current repair is due to damage. In total, the damage rate of innovative railcars is 42% higher than for standard railcars. Based on the analysis, the conclusion is made about imperfection of the current system of accounting for the operational work of railcars. The existing simplified accounting system for mileage and service life does not allow to identify the cause-and-effect relationship of occurrence of malfunctions.

Two-dimensional mesoporous materials (2DMMs) refer to thin two-dimensional (2D) nanosheets with randomly dispersed or ordered mesopores, which can combine the advantages of 2D materials and mesoporous materials while overcoming their inherent drawbacks, leading to enhanced application performance. A self-assembly strategy has been recognized as a promising manufacturing method for 2DMMs with customized performance. Over the past decades, encouraging progress has been made in the development of 2DMMs via the self-assembly strategy with a variety of compositions, morphologies, mesoporous structures, and pore sizes. Here, we provide a comprehensive review on recent progress in the fabrication of 2DMMs through this strategy, focusing on the synthesis methods, including molecular self-assembly methods, single micelle assembly methods, multi-templates methods, surface-limited co-assembly methods, and template-free methods. In addition, we set out the challenges faced by 2DMMs in future research and point out potential development directions.

This study aims to examine dividend policies for companies listed on the Indonesia Stock Exchange during the 2018-2022 period. Agency theory argues that dividend policy can reduce agency costs and reduce agency conflicts. The percentage of institutional ownership is used as a proxy for agency costs and can be used as a mechanism for lowering agency conflict. The total sample is 44 companies listed on the IDX. The estimation uses the pooling data method and 3SLS. This research develops a simultaneous system econometric model. This study argues that high institutional ownership leads to higher agency conflict, as management and institutions collaborate to prioritize their interests over other shareholders. Conversely, low institutional ownership leads to disputes between management, low institutional, and public shareholders. The entrenchment argument predicts higher conflict in high institutional ownership, while the convergence argument predicts common agency conflict in common institutional ownership.

Authors: Siemers Kyle M. , Klein Abigail K. , Baack Michelle L.
Published: August 2023

Polycystic ovary syndrome (PCOS) is a complex, but relatively common endocrine disorder associated with chronic anovulation, hyperandrogenism, and micro-polycystic ovaries [1]. In addition to reduced fertility, people with PCOS have a higher risk of obesity, insulin resistance, and metabolic disease [1], all comorbidities that are associated with mitochondrial dysfunction. This review summarizes human and animal data that report mitochondrial dysfunction and metabolic dysregulation in PCOS to better understand how mitochondria impact reproductive organ pathophysiology. This in-depth review considers all the elements regulating mitochondrial quantity and quality, from mitochondrial biogenesis under transcriptional regulation of both the nuclear and the mitochondrial genome, to the ultrastructural and functional complexes that regulate cellular metabolism and reactive oxygen species production, to dynamics which regulate subcellular interactions that are key to mitochondrial quality control. When any of these mitochondrial functions are disrupted the energetic equilibrium within the cell changes, cell processes can fail, and cell death can occur. If this process is ongoing, it affects tissue and organ function to cause disease. The objective of this review is to consolidate and classify a broad number of PCOS studies to understand how various mitochondrial processes impact reproductive organs including the ovary (oocyte and granulosa cell), uterus, placenta, and circulation to cause reproductive pathophysiology. A secondary objective is to uncover the potential role of mitochondria in transgenerational transmission of PCOS and metabolic disorders.
