Вплив цукрового діабету 2-го типу на віддалені результати хірургічного лікування катаракти
Authors: Zhaboiedov D.H. , Kyrpichnikov O.V.
Published: April 2023

Актуальність. Основною проблемою при цукровому діабеті (ЦД) є неконтрольований високий рівень глюкози в крові — гіперглікемія, яка призводить до вироблення кінцевих продуктів глікування, посилення окиснювального стресу та активації поліолового шляху утилізації глюкози, що зрештою може призвести до розвитку катаракти. Але, незважаючи на останні технічні досягнення в галузі хірургії катаракти — мінімізацію операційного розрізу, зниження часу впливу та потужності ультразвуку, дозована фізична травма ока під час операції, як і раніше, залишається провідною причиною розвитку післяопераційної неінфекційної ексудативно-запальної реакції. Матеріали та методи. Під спостереженням перебувало 165 пацієнтів (296 очей). 1-шу групу спостереження становили 80 пацієнтів (146 очей) із катарактою, хворих на ЦД 2-го типу, яким виконувалася факоемульсифікація (ФЕК) з імплантацією інтраокулярної лінзи (ІОЛ). ЦД 2-го типу у всіх пацієнтів був компенсований за даними дослідження показників вуглеводного обміну (рівень глюкози венозної плазми натще і вміст глікованого гемоглобіну). У всіх пацієнтів супутньою була легка або помірна непроліферативна діабетична ретинопатія (НПДР) відповідно до Міжнародної шкали тяжкості діабетичної ретинопатії Американської академії офтальмології (2002 рік). Групу контролю становили 85 хворих (150 очей) із віковою катарактою без супутніх захворювань, яким також виконувалася ФЕК з імплантацією ІОЛ. Результати. Після виконання ФЕК з імплантацією ІОЛ у пацієнтів із ЦД 2-го типу через 1 рік спостережень некоригована гострота зору статистично значуще нижча на 25 % (t = 7,42; p ≤ 0,01), максимально коригована гострота зору нижча на 16 % (t = 4,95; p ≤ 0,01) порівняно із пацієнтами без діабету. Частота післяопераційних ускладнень через 1 рік у середньому становила 6,83 % і була вища в 3 рази, ніж у пацієнтів без діабету (контрольна група) (χ21 рік = 3,617, p = 0,05), показник ВОТ вищий на 11 % (t = 4,08; p ≤ 0,01), середня кількість ендотеліальних клітин нижча на 4 % (t = 4,08; p ≤ 0,01), середня товщина фовеолярної зони сітківки вища на 10 % (t = 6,58; p ≤ 0,01). Частота запальних ускладнень у пацієнтів з ЦД 2-го типу в середньому становила 20,91 %, що було статистино значуще вище у 10 разів, ніж у пацієнтів контрольної групи, у яких їх частота становила 2 % (χ2 = 22,506, p < 0,001). Після виконання ФЕК з імплантацією ІОЛ при ЦД 2-го типу в 16,67 % випадків зафіксовано перехід в тяжку стадію НПДР.

Detection of Ring Structures and Their Surrounding Tectonic Pattern in South-Algeria, North-Mali and North- Niger based on Satellite Data
Authors: Theilen-Willige Barbara
Published: April 2023

This study is focused on the detection of circular features with different sizes, origins, and state of erosion as well as on their surrounding tectonic pattern based on different satellite images of Southern Algeria, Northern Mali and Northern Niger. Sentinel 2- and Landsat 8/9-images and Sentinel 1- and ALOS L-band Phased Array Synthetic Aperture Radar (PALSAR)-radar data help to identify larger ring structures and smaller circular features, most of them related to magmatic intrusions into the subsurface, but also to cosmic impacts, with varying ages and state of erosion. Some of them seem to be unknown so far as they are partly covered by aeolian sediments and become only visible on radar images. Digital Elevation Model (DEM) data and the DEM derived morphometric maps support these investigations in a GeoInformation System (GIS) embedded environment. Some of the ring structures are only visible on morphometric maps, traced by circular arrangements of slope gradients or concentric drainage patterns. The large, circular structures and the smaller circular features such as volcanic features (cinder cones, calderas, maars, impact craters) were digitized and merged in a GIS with available geologic information.

Impact of negative life events on adolescent suicide attempts: A moderated mediation analysis
Authors: Zhao Xiuli , Feng Junguo , Chen Xiongfei , Ma Zaoming , Chen Zhongwei , Zhang Libing , Li Menghua , Wu Sanmei , Chen Xiaofei
Published: April 2023

Suicide is a major public health problem among adolescents, and negative life events (NLE) have been considered a significant risk factor for suicide attempts. However, the mediating and moderating processes underlying the relationship between NLE and suicide attempts have remained
obscure. We examined both the mediating role of depression and the moderating role of peer support underlying this relationship. The results showed that depression fully mediated the positive relationship between NLE and adolescent suicide attempts. A moderated mediation analysis further revealed
that the indirect path from NLE to suicide attempts was moderated by peer support. These findings suggest that the development of depression plays a key role in explaining why adolescents who have experienced NLE are at a greater risk of suicide attempts than those who have not. A healthy
peer support system could serve as a buffer to reduce the adverse outcomes resulting from NLE. Overall, the results may contribute to developing an integrative framework of theory and effective interventions.

With the help of high-frequency currents, hardening coatings of increased hardness are applied to the working bodies of agricultural machines. When evaluating the effectiveness of these methods, along with studying the basic physical and mechanical properties of coatings, it is necessary to know the level of residual stresses in the coatings obtained. (Research purpose) The research purpose is studying the features and evaluate the possibilities of using coercimetry as an objective and reliable method for determining the stress state of flat knives hardened by HDPE boration. (Materials and methods) Samples of 65G steel in the initial state and flat mower knives reinforced with HDPE boration were prepared for the study. Performed the work in accordance with the current GOST 58599-2019 "Technical diagnostics. Diagnostics of steel structures. Magnetic coercive method. General requirements". Bursting machines, a magnetic structroscope (coercitimeter) were used KRM-C-K2M and devices for determining hardness and microstructure. (Results and discussion) At the first stage, the expected values of the coercive force for 65G steel were calculated depending on the chemical composition. As a result of mechanical tests of 65G steel samples for tensile strength with simultaneous measurement of coercive force, experimental data were obtained for constructing calibration curves, which were used to determine stresses in hardened knife samples after HDPE boration. It was determined that the residual stresses in hardened flat knives vary from 400 to 730 megapascals. These stresses can be considered acceptable (safe), since the yield strength for 65G steel is 685-785 megapascals. (Conclusions) The method of measuring coercive force makes it possible to estimate the degree of change in residual stresses in parts hardened by HDPE boration methods.

In hop production, the main scientific problem is the low energy efficiency of hop dryers with convective heat supply and the absence of small-sized mobile continuous-flow hop dryers for farms that ensure the preservation of the consumer properties of hops at reduced operating costs. In order to reduce the operating costs of drying hops, work is being carried out aimed at clarifying the drying modes that contribute to the best preservation of consumer characteristics, and the improvement of technologies and technical means that would reduce operating costs. A new method of drying hops by ultra-high-frequency energy supply deserves attention. (Research purpose) The research purpose is revealing the effectiveness of an ultrahigh-frequency convective hop dryer of continuous-flow action by evaluating the developed structural designs of hop dryers with metal-dielectric resonators that ensure uniform drying and disinfection of freshly harvested hops and electromagnetic safety without a shielding housing at reduced operating costs in the conditions of hop farms. (Materials and methods) Carried out three-dimensional modeling of the structural designs of hop dryers in the Compass 20 program, determined the electrodynamic parameters of the ”generator-resonator“ system in CST Microwave Studio. (Results and discussion) Solved the problem of optimizing the structural design and dimensions of metal-electric resonators. It was shown that the main criteria are the correctly agreed parameters of the electrodynamic system ”generator-resonator“: the intrinsic Q-factor of the resonator, the voltage of the electric field, its uniformity of distribution, the power of the radiation flux, the volume of the resonator. The electro-dynamic parameters of 11 hop dryers with different designs of resonators were analyzed: hemispherical, semi-cylindrical, cylindrical, toroidal, prismatic, ellipsoid and others. (Conclusions) It was found that toroidal and hemispherical resonators have a maximum intrinsic Q-factor of up to 8000. It was determined during the evaluation of deviations from the average value of the intervals of variation of the criteria that hop dryers with resonators in the form of a paraboloid and hyperboloid, and semi-cylindrical, are effective.

This research is motivated by the increasing competitiveness potential of private Islamic elementary schools in Indonesia. Competition in the education sector is characterized by the relevance of community needs, oriented to modernity with the principle of mutual justice, and substance oriented in harmony with global cooperation and competition. Educational competitiveness requires leadership support in improving and developing the quality of education (Waruwu et al., 2022). However, little is known about the support of visionary leadership and improving the quality of school competitiveness. This study aims to explore the support of visionary leadership and the quality of education on the competitiveness of schools. This study uses descriptive quantitative research methods to determine the average of each variable and continues with the correlational method. The instrument was a closed questionnaire distributed to 59 Islamic elementary schools in East Jakarta. The respondents are teachers and parents who are members of the school committee management team. A total of 481 respondents consisted of 222 teachers and 259 representatives of parents. The results showed that visionary leadership support, quality improvement, and school competitiveness were in the high category at private Islamic elementary schools in East Jakarta, Indonesia. All variables partially have a significant effect on school competitiveness. This study recommends that principals and stakeholders are committed to continuously improving schools’ quality to match global competitiveness. Therefore, visionary leadership skills are needed so that school principals are able to think far ahead and are global so that challenges can be faced and competition can be conquered.

Motivational Optimism and Short-Term Investment Efficiency
Authors: Li Meng , Markov Stanimir , Shu Susan
Published: April 2023

We explore whether managers’ strong desire for good performance distorts their expectations and, consequently, corporate investment efficiency. We find that managers overweight favorable information and underweight unfavorable information, resulting in optimistic earnings guidance. We construct an ex ante measure of optimism and show that greater optimism is associated with a lower inventory investment efficiency: Managers overinvest in inventory, resulting in lower inventory turnover and increased incidence and severity of inventory writedowns. We also find motivational optimism influences firms’ financial reporting and is associated with an increased incidence of financial misreporting. Our results are consistent with the psychology theory of motivated reasoning, which emphasizes the distortive effects of preferences on beliefs and judgments.

Cox-Lognormal Model to Assess Longevity in Curraleiro Pé Duro Cattle Breed from the Semiarid Region of Brazil
Authors: Soares Keliny Martins de Melo Sousa
Published: April 2023

Cattle of the Curraleiro Pé Duro breed are characterized as very docile and exceptionally rustic animals. They are animals gradually adapted to low quality native pastures, drought conditions, high temperatures and other adverse factors, resulting in the formation of bovine herds adapted and resistant to the unfavorable conditions of the Brazilian hinterland. In this context, the objective of this work was to use the survival analysis methodology with a Cox-lognormal proportional hazards model, to assess the stayability in the herd, considering the failure as the inactivity of the bovine being caused by death or sale, using information from 102 Curraleiro Pé Duro cattle born in the period from 2005 to 2014 in an experimental field of Embrapa Meio-Norte located in São João do Piauí. The Cox-lognormal proportional hazards model considered, among the analyzed covariates, the season of birth, sex and weight at 365 days as significant. There was a predominance of birth in the dry season (July to December). It was observed that the cattle that longer remained in the herd were born in the dry season, were male and weighed less than 95 kg at 365 days, justified by the absence of parasites, availability of pasture for the mother during the pregnancy period, carcass evaluation, sale, slaughter and reproduction. The Cox-lognormal proportional hazards model proved to be adequate in the adjustment of the statistical model to estimate the stayability in the herd, with censorship related to the inactivity of the Curraleiro Pé Duro breed.

Motivasi belajar peserta didik cenderung rendah. Hal ini disebabkan karena siswa menganggap bahwa pembelajaran matematika adalah pelajaran yang sulit dan membosankan. Kenyataan dilapangan menunjukkan bahwa tidak semua guru mengetahui tingkat motivasi belajar siswa, sehingg guru cenderung telat untuk memberikan penanganan. Salah satu upaya yang dapat dilakukan yakni dengan mengembangkan sebuah instrument penilaian motivasi belajar matematika dengan tujuan untuk mengembangkan instrumen motivasi belajar matematika untuk siswa kelas V Sekolah Dasar dan mengetahui validitas serta reliabilitas instrumen motivasi belajar matematika. Penelitian ini tergolong kedalam jenis penelitian pengembangan yang dikembangkan dengan menggunakan model 4D yaitu define, design, develop & disseminate. Subjek yang terlibat dalam penelitian ini yakni 2 orang dosen dan 2 orang guru sekolah dasar. Analisis validitas instrument menggunakan rumus CVR dan CVI. Uji reliabiltas menggunakan rumus Alpha Cronbach. Berdasarkan hasil analisis diketahui bahwa terdapat 6 butir soal yang memiliki nilai CVR=0,50 yang dinyatakan tidak valid atau perlu revisi, dan 42 butir soal dinyatakan valid. Hasil uji validitas instrument menunjukkan bahwa CVI = 0,94 dinyatakan istimewa dan reliabilitas instrument ini adalah 0,960 dengan kategori sangat tinggi. Sehingga dapat dikatakan bahwa instrument penelitian motivasi belajar matematika siswa berada dalam kategori valid dan layak untuk dikembangkan.
Comparative analysis of the principles of Civil Procedural Law and Ecclesiastical Procedural Law in Romania
Authors:   “Valahia” University, Târgoviște, Santi Cosmin
Published: April 2023

Principles represent general rules, basic concepts, which serve to underpin and prepare the legal framework for the development of a complex trial or synthesize a social and juridical experience, thereby assuring a balance and a relation between the rights and the obligations of a person and of society as a whole. The principles of civil procedural law manifest themselves in the form of basic juridical concepts. These determine the forms and methods of juridical regulation of procedures for examining and resolving litigation brought before the civil courts. The fundamental canonical principles of Orthodoxy are comprised, on the one hand, of the universal constitution of the Church, mirrored in the collection of holy canons, and on the other hand, of the Church’s long and constant practice and tradition, become canon law custom. These principles consist both of natural and, especially, supernatural revelation, in the form of the truths of faith included in the Holy Scriptures and the Holy Tradition and in the objective conditions of the natural life of society. Both the general principles of civil law and those of canon law represent the solid basis of the general system of law, a structure on which the whole juridical architecture is built, meant to assure not only correct and coherent legislation, but also a balanced and transparent justice, via a unitary and consistent judicial practice or jurisprudence.
Directorio de Amazon: una representación de mujeres por sobre la media y un compromiso de negocio plenamente sostenible
Authors: Castillo Osvaldo Jorge
Published: April 2023

Los excelentes indicadores que viene reflejando últimamente la empresa Amazon se deben en gran medida, a la convergencia de un acertado liderazgo su modelo de negocio –mayoritariamente basado en el ecommerce– y unido a lo anterior, oportunidades globales excepcionales para la empresa debidas , a la pandemia del COVID-19. Ahora bien, debemos destacar la fortaleza de su Directorio, poco mencionada y eclipsada tal vez, por la figura carismática de su ahoraex-CEO y fundador, Jeff Besos. Al respecto, hace años que en su estructura se viene incorporando presencia de mujeres, llegando al 45 % en el año 2020, lo que la ubica muy por encima de la media de los Estados Unidos que fue del 28,2% para ese mismo año. Además de sus logros económico-financieros ha sido los dos últimos años la segunda empresa más importante de EE UU Entre otros retos, se ha comprometido públicamente en el año 2019lograr la neutralidad en emisiones de carbono para 2040, 10 años antes de lo establecido en el Acuerdo de París. Si bien los datos no demuestran que exista relación de causalidad entre el porcentaje de mujeres en su Directorio y el desempeño excelente, sí podemos afirmar que la representación equilibrada de mujeres en su Directorio es una fortaleza que a las claras mejora su reputación –reflejada en sus indicadores económico-financieros y en su compromiso de negocio plenamente sostenible–.

The study aims to determine the types of edible wild plants and fruits consumed in the culinary cultures of Yozgat and Sivas, their ethnobotanical characteristics, and the areas and forms of their uses. In the research, document analysis and semi-structured interviews were used as data collection techniques, and descriptive analysis was used as the data analysis method. The categories obtained as a result of the interview findings and the literature review consist of the areas of the uses of edible wild plants and fruits in the kitchen, their use patterns, their relationship with health, and the methods of cultivating and preserving edible wild plants and fruits. Research findings indicate that the tradition of using edible wild plants and fruits is still alive in Yozgat and Sivas.
La diferencia ontológica según las maneras del ser en la ontología-fundamental
Authors: Ivanoff-Sabogal Christian
Published: April 2023

Esta investigación aborda el tema de la diferencia ontológica desde la perspectiva de las maneras del ser (ser-cómo), uno de los momentos constitutivos de la idea complejo-unitaria del ser. Tema y perspectiva se complementan recíprocamente. Primero, la diferencia ontológica posibilita evidenciar el fenómeno óntico de las maneras de ser del ente y el ontológico de las maneras del ser. Segundo, ambas maneras proveen una palpable visualización sobre los términos de la diferencia ontológica, desbrozando el terreno para distinguir al ser, no sólo del ente, sino de la entidad, la cual está determinada unilateralmente por el ser-dado-delante (Vorhandenheit) en sentido amplísimo.
Voltaire lector de Castel de Saint‒Pierre
Authors: Ratto Adrián
Published: April 2023

Es un lugar común considerar a Voltaire como un crítico de  Castel de Saint‒Pierre y uno de los principales responsables de la recepción de su imagen como la de un  promotor de ideas impracticables, en particular su proyecto de paz permanente entre las naciones. El objetivo de este artículo es mostrar que, en cualquier caso, la interpretación que hace de los escritos del abate es menos simple de lo que se puede pensar en un primer momento. El trabajo busca poner de relieve los desplazamientos y torsiones que la figura de éste sufre en los escritos del filósofo francés, especialmente a partir de los años 50’, momento en el que revaloriza algunos aspectos de su obra. Por otra parte, el texto arroja algunas luces acerca de lo que podría considerarse el proyecto de paz del propio Voltaire.
Finite Length Triple Estimation Algorithm and its Application to Gyroscope MEMS Noise Identification
Authors: Macias Michal , Sierociuk Dominik
Published: April 2023

The noises associated with MEMS measurements can significantly impact their accuracy. The noises characterised by random walk and bias instability errors strictly depend on temperature effects that are difficult to specify during direct measurements. Therefore, the paper aims to estimate the fractional noise dynamics of the stationary MEMS gyroscope based on finite length triple estimation algorithm (FLTEA). The paper deals with the state, order and parameter estimation of fractional order noises originating from the MEMS gyroscope, being part of the popular Inertial Measurement Unit denoted as SparkFun MPU9250. The noise measurements from x, y and z gyroscope axes are identified using a modified triple estimation algorithm (TEA) with finite approximation length. The TEA allows a simultaneous estimation of the state, order and parameter of fractional order systems. Moreover, as it is well-known that the number of samples in fractional difference approximations plays a key role, we try to show the influence of applying the TEA with various approximation length constraints on final estimation results. The validation of finite length TEA in the noise estimation process coming from MEMS gyroscope has been conducted for implementation length reduction achieving 50% of samples needed to estimate the noise with no implementation losses. Additionally, the capabilities of modified TEA in the analysis of fractional constant and variable order systems are confirmed in several numerical examples.
Optimisation of ultrasonic-assisted extraction and biological activity of total flavonoids from leaves of Murrayae exotica using response surface methodology
Authors: Wen Yao , Liu Manchun , Mai Xueying
Published: April 2023

Murrayae exotica is a traditional Chinese medicine widely grown in southeast China. A Box–Behnken design of response surface methodology was employed to further optimise ultrasonic-assisted extraction conditions for M. exotica leaves total flavonoids (MELTF). The results showed that the optimised extraction conditions were an ultrasonic power of 240 W, an ultrasonic temperature of 60 °C, a solvent concentration of 76%, an ultrasonic time of 55 min and a liquid–solid ratio of 22 mL · g−1. Under these conditions, 8.59 ± 0.34 mg · g−1 was achieved as the mean experimental value of extraction yield, which amounts to 2.56 times that of ethanol leaching extraction. As compared to MELTF, MELTF after purification (MELPTF) had a higher purity of 9.96%, which was nearly nine times higher than that of MELTF (1.26%). As compared to MELTF, MELPTF had higher α-glucosidase and α-amylase inhibitory activities as well as DPPH· and ABTS·+ scavenging activities with IC50 values of 0.021, 0.094, 0.245 and 0.113 mg · mL−1, which are 1.33, 2.12, 3.17 and 1.78 times higher than those of MELTF (0.028, 0.199, 0.777 and 0.201 mg · mL−1). The study thus demonstrates the eligibility of MELPTF to be considered as a multifunctional bioactive ingredient having potential applications in anti-hyperglycaemic pharmaceutical formulation and as an antioxidant in functional foods.
