SPECIFIC ASPECTS AND OBJECTIVE SIGNS OF THE CRIME OF VIOLATION OF CUSTOMS LEGISLATION
Authors:   Tashkent State University of Law, Kholikov Farhod
Published: May 2023

In the article, the author describes some comments on the objective signs of the crime of violation of customs legislation. Also, according to the author’s note, in today’s developed market economy and globalization processes, no country can stay in its shell and live only at the expense of the products it produces. As long as there is a world market, there will be an international division of labor between countries, and export-import transactions for the exchange of goods. The type and quantity of such goods, of course, depends on the existing needs in a particular country. Each country is obliged to take these circumstances into account while organizing its economy. The experience of countries that try to live on the basis of a natural economy at the expense of the goods they produce shows that they are doomed to backwardness and poverty. However, in such conditions, it is of great importance that the goods entering the state territory meet the specified standards, type and quality. The importation of low-quality goods that do not meet the relevant standards into the territory of the country poses a threat not only to the health and life of the population but also to state security. For this reason, criminals who think of making less effort and more profit try to import (export) such goods into the territory of the country in different ways. Therefore, in order to prevent and combat similar situations in all countries, customs control is organized in the border areas of the country.

Published: May 2023

Osteoarthritis of the knee is a degenerative disease, usually the result of wear and tear and progressive loss of articular cartilage. Osteoarthritis is a progressive disease that can eventually lead to disability. Total knee replacement is considered an effective surgical treatment for severe degenerative osteoarthritis of the knee, to relieve pain, increase mobility, and improve quality of life in cases with excellent surgical outcomes. However, total knee replacement is associated with moderate to severe postoperative pain. Pain control remains a problem due to its subjective nature and the diversity of patients, which requires the search for new regimens and treatment methods. In recent years, the use of peripheral nerve blocks has become increasingly popular. Blockade of the adductor canal can significantly reduce opioid consumption and side effects associated with their use, which contributes to the early mobilization of operated patients. The object of the study was 138 total knee arthroplasty performed at the 6th City Clinical Hospital of Minsk in the period from 2017 to 2020.
THE INFLUENCE OF PHYSICO-PHARMACOLOGICAL EFFECTS ON THE CALCIUM CONTENT IN THE BLOOD SERUM OF EXPERIMENTAL ANIMALS
Authors:   Belarusian State Medical University, S. V. Ivashenko
Published: May 2023

The use of intraosseous dental implants allows solving many issues with partial and complete loss of teeth, restoring chewing function and improving facial aesthetics. And the rapid formation of a strong connection between the implant and the bone is the key to a successful result of the dental surgery. In this regard, it is of interest to develop a method for improving the biointegration of dental implants using magnetophoresis of medicinal substances, which significantly increases therapeutic efficacy. However, the issues of calcium content in its serum under the influence of the used therapeutic agents (surgical, physiotherapeutic, pharmacological) have not been sufficiently studied. Therefore, the purpose of this study was to determine the calcium content in the blood serum of experimental animals after the application of magnetophoresis solutions of 10% calcium gluconate and 5% retabolil. 16 rabbits of the "chinchilla" breed served as objects for fulfilling the goal of our work. The study made it possible to conclude that the magnetophoresis effects of calcium gluconate and retabolil solutions did not lead to a change in blood biochemistry and contributed to a short-term increase in the content of calcium and phosphorus in the blood serum of animals.

Published: May 2023

Abstract. Due to the complex radiative transfer process, the retrieval time of the physical retrieval algorithm is significantly increased compared with that of the statistical retrieval algorithm. The calculation of the Jacobian matrix is the most computationally intensive part of the physical retrieval algorithm. Further analysis showed that the changes in Jacobians had little effect on the performance of the physical retrieval algorithm. On the basis of the above findings, a fast physical-iterative retrieval algorithm was proposed by adaptively updating the Jacobian in keeping with the changes of the atmospheric state. The performance of the algorithm is evaluated using synthetic ground-based infrared spectra observations. The retrieval speed is significantly improved compared with the traditional physical retrieval algorithm under the condition that the parameters of the computing platform remain unchanged, with the average retrieval time reduced from 8.96 min to 3.69 min. The retrieval accuracy of the fast retrieval model is equivalent to that of the traditional algorithm, with maximum root-mean-square errors of less than 1.2 K and 1.0 g/kg for heights below 3 km for the temperature and water vapor mixing ratio (WVMR), respectively. The Jacobian updating strategy has a certain impact on the convergence of the retrieval algorithm, whose convergence rate is 98.7 %, which is lower than that of the traditional algorithm to some extent. However, reliable retrieval results can still be obtained by adjusting the convergence criteria.

Abstract. Black carbon (BC), the most efficient atmospheric aerosol for absorbing light in the visible spectrum, exerts a warming effect on a region undergoing unprecedented climatic changes. Here, BC is studied indirectly using filter-based methods to ascertain aerosol light absorption parameters. We investigated long-term changes using a harmonised 21-year data set of light absorption measurements, in conjunction with air mass source analysis. The measurements were performed at Zeppelin Observatory (ZEP), Svalbard, from 2002 to 2022. We report a statistically significant (s.s.) decreasing long-term trend for the light absorption coefficient, measured at the site for the entirety of the data set. However, the last 7 years, 2016–2022, showed a slightly increasing s.s. trend for the haze season. In addition, we observed an increasing trend in the single scattering albedo from 2002 to 2022. Five distinct source regions were identified; the trends involving air masses from the five regions showed decreasing absorption coefficients, except for the air masses influenced by emissions from Eurasia. We show that the changes in the occurrences of each transport pathway cannot explain the reductions in the absorption coefficient observed at the Zeppelin station; an increase in contributions of air masses from more marine regions, with lower absorption coefficients, is compensated by the influence from high-emission regions. Along with aerosol optical properties, we also show an increasing trend in accumulated surface precipitation experienced by air masses en route to the Zeppelin Observatory. We argue that rainfall, as a sink of aerosol, plays a role in the long-term trends in the absorption coefficient, explaining approximately a quarter of the overall trend. A decreasing trend in the scavenging ratio further suggests an increase in the aerosol removal processes. We note that there is an increasing potential influence from active forest fires, particularly in the last few summers (i.e. 2015–2022). Active fires have been shown to have a significant impact on the mean seasonal absorption coefficient especially during northern hemispheric summer. However, no noticeable alteration in annual long-term trends can be observed.

Abstract. We present analyses of a 12-year time series of continuous atmospheric measurements of O2 and CO2 at the Weybourne Atmospheric Observatory in the United Kingdom. These measurements are combined into the term Atmospheric Potential Oxygen (APO), a tracer that is conservative with respect to terrestrial biosphere processes. The CO2, O2 and APO datasets discussed are hourly averages between May 2010 and December 2021. We include details of our measurement system and calibration procedures, and describe the main long-term and seasonal features of the time series. The 2-minute repeatability of the measurement system is approximately ±3 per meg for O2 and approximately ±0.005 ppm for CO2. The time series shows average long-term trends of 2.40 ppm yr-1 (2.38 to 2.42) for CO2, -24.0 per meg yr-1 for O2 (-24.3 to -23.8) and -11.4 per meg yr-1 (-11.7 to -11.3) for APO, over the 12-year period. The average seasonal cycle peak-to-peak amplitudes are 16 ppm for CO2, 134 per meg for O2, and 68 per meg for APO. The diurnal cycles of CO2 and O2 vary considerably between seasons. The datasets are publicly available at https://doi.org/10.18160/Z0GF-MCWH (Adcock et al., 2023) and have many current and potential scientific applications in constraining carbon cycle processes, such as investigating air-sea exchange of CO2 and O2, and top-down quantification of fossil fuel CO2.

Published: May 2023

Abstract. Land surface models (LSMs) use the atmospheric grid as their basic spatial decomposition because their main objective is to provide the lower boundary conditions to the atmosphere. Lateral water flows at the surface on the other hand require a much higher spatial discretization as they are
closely linked to topographic details. We propose here a methodology to automatically tile the atmospheric grid into hydrological coherent units
which are connected through a graph. As water is transported on sub-grids of the LSM, land variables can easily be transferred to the routing
network and advected if needed. This is demonstrated here for temperature. The quality of the river networks generated, as represented by the
connected hydrological transfer units, are compared to the original data in order to quantify the degradation introduced by the discretization
method. The conditions the sub-grid elements impose on the time step of the water transport scheme are evaluated, and a methodology is proposed to
find an optimal value. Finally the scheme is applied in an off-line version of the ORCHIDEE (Organising Carbon and Hydrology In Dynamic Ecosystems) LSM over Europe to show that realistic river discharge
and temperatures are predicted over the major catchments of the region. The simulated solutions are largely independent of the atmospheric grid used
thanks to the proposed sub-grid approach.
CROSS-LANGUAGE TRANSFER LEARNING USING VISUAL INFORMATION FOR AUTOMATIC SIGN GESTURE RECOGNITION

Published: May 2023

Abstract. Automatic sign gesture recognition (GR) plays a critical role in facilitating communication between hearing-impaired individuals and the rest of society. However, recognizing sign gestures accurately and efficiently remains a challenging task due to the diversity of sign languages (SLs) and their limited availability of labeled data. This scientific paper proposes a new approach to improving the accuracy of automatic sign GR using cross-language transfer learning with visual information. Two large-scale multimodal SL corpora are utilized as the basic SLs for this study: the Ankara University Turkish Sign Language Dataset (AUTSL) and the Thesaurus Russian Sign Language (TheRusLan). Experimental studies were conducted, resulting in an accuracy of 93.33% for 18 different gestures, including the Russian target SL gestures. This result exceeds the previous state-of-the-art accuracy by 2.19%, demonstrating the effectiveness of the proposed approach. The study highlights the potential of the proposed approach to enhance the accuracy and robustness of machine SL translation, improve the naturalness of human-computer interaction, and facilitate the social adaptation of people with hearing impairments. This paper proposes a promising direction for future research to explore the application of the proposed approach to other SLs and to investigate the impact of individual and cultural differences on GR.

Abstract. Data from the Copernicus project are proving to be fundamental in so many areas of spatial governance, and in particular in the context of safeguarding the cultural and natural heritage. This is mainly due to their dissemination mode, which allows them to be used by a countless number of institutions and organizations. With regard to their use in order to create effective supervised-training AI (Artificial Intelligence) classifiers (useful for continuous land-use monitoring), their low resolution could be a problem in terms of accuracy or in any case during the training process. This process which could be very costly (large training sets and high-end hardware required). In this paper, a methodology is tested that creates an AI classifier from high-resolution training data, Remote Sensing Image Classification Benchmark (RSI-CB128) and using Self-Normalising Neural Networks (SNNs). The efficiency of the Neural Network is, however, measured with a test dataset constructed with Raster Sentinel-2. In other words, the aim is to assess the goodness of an AI classifier on Sentinel-2 images built from Rasters generated by high-resolution sensors. Therefore, there seem to be clear advantages over the classification methodologies in use today.

Published: May 2023

Abstract. This paper contains a description of computational experiments on the application of elastic maps to the analysis of time-varying volumes of textual information. Elastic maps are considered as a tool to provide analytical work with textual information and large information arrays of data. This paper presents the results of numerical experiments on the study of data volumes consisting of frequencies of joint use of words from different parts of speech, for instance “noun + verb” or “adjective + noun”. We consider text collections in Russian for experiments. Previously, static information arrays were mostly considered. It is for them methods of data analysis and methods of visual analytics were developed. Nevertheless, data comes in all the time in various areas of human activity. And in practice it is necessary to know how the cluster picture of multidimensional data volume changes over time. The paper describes the numerical experiments for real time-varying multidimensional data sets. Such experiments allows to analyze the evolution of cluster structure for multidimensional data and to trace the evolution for separate cluster.

Authors: Wade Carol Henderson , Wilkens Christian , Sonnert Gerhard , Sadler Philip
Published: May 2023

Although the secondary-tertiary transition has been investigated in mathematics education research with different focuses and theoretical approaches, it remains a major issue for students in the transition. With success in a science, technology, engineering, or mathematics (STEM) major at stake, we investigated a novel approach to support the transition from secondary precalculus or calculus to tertiary calculus. Using the Four Component Instructional Design (4C/ID) model and empirical data from the United States (US) nationally representative FICSMath project, we mapped instructional experiences of students in the transition to theoretical components of the 4C/ID model. From exploratory factor analysis (n=6,140), we found six factors that mapped to the 4C/ID model components and created the new Secondary Precalculus Calculus (SPC) 4C/ID model. In this model, the Learning Task Component represents tasks to engage learners in meaningful problem solving; the Support Component grounds instruction in reasoning and understanding; the Procedure Component integrates group work and graphing calculators to connect concepts to procedures; and the Part-Task Component represents instruction to develop automaticity. The SPC 4C/ID model presents a unique support for precalculus and calculus teachers in the quest of teaching for learning and transfer of learning across the transition.

The development of new magnetic fluorescent materials is of great significance for identification and criminal investigation. Since the photosensitive elements used in conventional cameras have exhibited the highest quantum efficiency in the range of 500–700 nm, lanthanide-based upconversion nanoparticles (UCNPs) with main emission peaks at 507–533 nm, 533–568 nm and 637–683 nm are suitable for constructing magnetic fluorescent materials. In this work, we demonstrate a type of magnetic upconversion nanoparticle (MUCNP) of NaGdF4:Yb,Er-Fe3O4 by a ligand-linked method. After optimizing the reaction parameters, the composite particles possess remarkable magnetic properties and upconversion fluorescence intensity and achieve high contrast for latent fingerprint recognition on various substrates. The combination of upconversion luminescence and magnetism contributes to good fingerprint recognition sensitivity and universality.

Published: May 2023

An optimization algorithm for a robotic technological complex for laser cutting is proposed, while restrictions

are imposed on the angles in the joints of the robot and restrictions that take into account the orientation

of the cutting technological tool. The developed algorithm also makes it possible to minimize the scope of the robot's

movements when forming the laser's trajectory. The effectiveness of the proposed approach is evidenced by the

results of testing in the environment of computer simulation of robotic technological complexes on the example

of a robotic manipulator FANUC M-710iC/50 with 6 degrees of freedom.

Amaç: Bu araştırma bir üniversite hastanesinde çalışan hemşirelerin hastane infeksiyonlarını önlemede izolasyon bilgi ve uyum düzeylerini belirlemeyi amaçlayan tanımlayıcı bir araştırmadır. Gereç ve Yöntemler: Araştırma üniversite hastanesinin dahili ve cerrahi kliniklerinde en az bir yıldır çalışmakta olan gönüllü 220 hemşire ile gerçekleştirildi. Veriler Şubat 2021-Nisan 2021 tarihleri arasında anket yöntemi ile elde edildi. Verilerin toplanmasında araştırmacı tarafından oluşturulan anket formu ve Tayran tarafından geliştirilen “İzolasyon Önlemlerine Uyum” ölçeği kullanıldı. Verilerin analizinde IBM SPSS 24 programı kullanıldı.

Bulgular: Katılımcıların yaş ortalamasının 31,56±8,80 olduğu ve %84,1’inin kadın olduğu saptandı. Çalışmada hastane infeksiyonu ve izolasyon bilgi puanı ortalaması 60.00±16.33; İzolasyon önlemlerine uyum ölçek puan ortalaması 68.04±6.59 olarak bulundu. Cinsiyet ve medeni durumun izolasyon önlemlerine uyumu etkilediği; medeni durum, eğitim düzeyi, çalışma yılı ve çalışılan birimin bilgi puanlarını etkilediği belirlendi. İzolasyon bilgi puanı ile izolasyon uyum ölçek puanı arasında herhangi bir korelasyon bulunamadı. Katılımcıların en çok hastanın ve hekimlerin izolasyon önlemlerine uymamaları ve malzeme eksikliği konularında sorun yaşadıkları belirlendi.

Sonuç: Sonuç olarak hemşirelerin hastane infeksiyonu ve izolasyon bilgi puanının düşük, izolasyon önlemlerine uyumlarının orta derecede olduğu görüldü. Cerrahi birimlerde çalışan hemşirelerin izolasyon uygularken daha fazla sorun yaşadıkları ve en fazla problemin ise hasta ve hekimlerin izolasyon önlemlerine uymamasından kaynaklandığı bulundu. Hizmet içi eğitimlerde uygun tekniklerin kullanılması ve denetimlerin arttırılması, hasta ve hekimlerin izolasyon önlemlerine uymama nedenlerinin araştırmalar yapılması önerilmektedir.

Published: May 2023

Objective: This study aims to determine the effect of planned educatıon made on the web envıronment for fathers wıth preterm chıldren on the perceptıon of the role of fathers and care skılls
Methods: This research, planned in a quasi-experimental type, involved 30 study-30 control groups of fathers. The data were collected web-based using the Introductory fact sheet, marriage fit scale, fatherhood role perception scale, and successful test for prematurely born baby care. In the analysis of the data, descriptive statistics, chi-square, t-test in independent groups, and analysis of variance were used in repeated measurements.
Results: The mean age of fathers was 29.46±4.52 for working group fathers and 31.6±4.78 for control group fathers. After web-based education, it was found that the average score for marital compliance was higher in working group fathers than fathers in the control group. It was determined that the perceptions of the fatherhood role were high after education, especially among fathers in the study group. Positive perceptions of fatherhood role from the lower dimensions of the scale and perceptions of fatherhood role in child sexuality were found to be high in the lower dimension of the scoring average, and negative perceptions of fatherhood role were low in the lower dimension score average.
Conclusion: According to our research results, the web-based education-oriented initiative was found to be effective in fathers' marital harmony, fatherhood role perception, and success tests. This study is a good indicator that an innovative approach can be effective in education. It is recommended that this topic be examined in a qualitative dimension with different research designs with more widely attended samples.

Este documento corresponde a la segunda parte del Tercer Consenso Argentino sobre el manejo de los trastornos bipolares, enfocada en sintetizar la evidencia actualizada sobre los abordajes terapéuticos de esta patología en los pacientes adultos. Siguiendo la metodología descripta en la primera parte del Consenso, el panel de expertos realizó una exhaustiva revisión de la bibliografía y, como consecuencia de un posterior debate sobre la información disponible, se generó esta sección A del segundo documento que abarca el tratamiento integral de las personas adultas que padecen este trastorno. Durante la etapa de debate y discusión de estas guías, se decidió incorporar algunos puntos que estimamos serán de gran utilidad para el equipo interdisciplinario encargado del manejo de pacientes con trastornos bipolares. En tal sentido, en la sección A de la segunda parte de este documento, se podrán encontrar las recomendaciones generales para el uso de las guías de tratamiento, los niveles de evidencia disponibles para sustentar las recomendaciones, las consideraciones generales del tratamiento de los trastornos bipolares, el fenómeno de pseudorresistencia y adherencia al tratamiento, las consideraciones generales sobre el abordaje psicológico, así como el tratamiento a largo plazo de los trastornos bipolares.
Cuando los procedimientos judiciales facilitan el abandono. Nuevas formas de Ghosting
Authors: Delucchi Gustavo A.
Published: May 2023

El ghosting (fantasmeo o desaparición) se estableció como una forma de terminación de relaciones breves y sin compromiso. Consiste simplemente en cortar todo tipo de comunicación y no dar señales de vida de forma abrupta. Por otro lado, los informes psicológicos en los tribunales de familia, habitualmente se limitan a transcribir los dichos de las partes entrevistadas, sin efectuar ningún otro acto profesional que no sea el mero relato. Esto, sumado al no seguimiento de los procedimientos de la ley, terminan facilitando el cese abrupto no de relaciones cortas, sino parejas de larga data, o hasta inclusive matrimonios, mediante exclusiones de hogares o imposición de perímetros de exclusión, con las innumerables consecuencias para la persona ghosteada y la familia. Se intenta advertir, sobre la necesidad de la realización de verdaderos informes periciales, que ayuden a los magistrados a mejorar la toma de decisiones, que no faciliten la finalización abrupta de relaciones familiares de larga data.
Diversidad de la comunidad de macroinvertebrados acuáticos en el río juan lópez, atlántida (Honduras ) en época seca

Published: May 2023

Durante la época seca del año 2016, en el río Juan López en El Porvenir (Atlántida), se evaluó la diversidad de la comunidad de macroinvertebrados acuáticos en un transecto de la cuenca baja me- diante índices ecológicos, algunos parámetros fisicoquímicos y la composición del sustrato en el fondo del río. Se extrajeron muestras compuestas de sedimentos en 5 sitios con ayuda de una draga y se cuantificaron e identificaron. Fueron encontrados un total de 9.457 ind.m-2 pertenecientes a la comu- nidad de macroinvertebrados distribuidos en 4 phylum, 9 clases, 19 órdenes y 27 familias. El sitio del río más próximo a la zona costera presentó la mayor densidad de organismos en todas las categorías taxonómicas. El phylum arthropoda representó el 75.94 % de abundancia relativa, la clase insecta el 34.46 % de abundancia relativa, orden diptera con 34.30 % de abundancia relativa y la familia Chiro- nomidae con 35.35 %. El contenido de partículas finas en el sedimento es alto en general y las texturas que predominan en las secciones de sedimento evaluadas fueron entre limoso y franco limoso, pro- bablemente, debido a procesos de erosión y sedimentación en la cuenca provocados por la actividad agrícola. Los organismos identificados con mayor presencia son los más resistentes y oportunistas ante estos procesos. En los sitios con menor contenido de materia orgánica y mayor contenido de partículas finas, tuvieron menores diferencias en diversidad (H') y diversidad máxima (Hmax).
