Modern view of the problem: the influence of obesity as a key component of metabolic syndrome on the development and progression of endometrial cancer
Authors: Pavlov A. Yu. , Dzidzariya A. G. , Kalinchenko S. Yu. , Muravyeva P. V.
Published: July 2024

Unlike many other malignancies, the incidence and mortality of endometrial cancer continues to rise. This unfortunate trend is in no small part the result of the worldwide obesity epidemic, which is caused by reduced physical activity, poor diet and chronic stress. Currently, more than 50 % of endometrial cancer cases are associated with obesity, which is recognized as an independent risk factor for the development of this disease. Adipose tissue is not only the main place of storage of excess energy, but also a full-fledged endocrine organ that affects the metabolism, immune response and production of biologically active substances involved in cell growth and differentiation, angiogenesis, apoptosis and carcinogenesis. In this review, we assess the impact of obesity as a key component of metabolic syndrome on the development and progression of endometrial cancer. There are several mechanisms by which obesity enlarges the risk of endometrial cancer, including increased endogenous sex steroid hormones, hyperglycemia, insulin resistance, adipokine secretion, and chronic inflammation.

   The purpose of this review is to analyze publications, reflecting the already known aspects of the biological effect of obesity, as well as new data from recent years.

Published: July 2024

In Colombia, several wetlands have experienced significant changes in the water mirror, either by natural or anthropogenic processes; most of these wetlands show eutrophication, a fact that is evidenced by the uncontrolled proliferation of algae, herbaceous and sedges, making them vulnerable to phenomena such as global warming. This study focuses on the Torca - Guaymaral wetland located in the extreme north of the city of Bogotá (Colombia), which is currently affected by the rapid spread of hydromorphic vegetation. This aquatic ecosystem is habitat for countless species, while at the same time providing multiple benefits to society as an urban wetland. The analysis of the study area was performed based on vegetation and humidity in comparison with the data yielded by the NDVI and NDWI indices in the years 2014 and 2023 in the months of January and February, respectively. The wetland maps are made using ArcGIS software to process Landsat 8-9 satellite images, with a cloud cover range below 60 % and downloaded from the USGS EarthExplorer platform. The results indicate the decrease of wetlands in the Torca-Guaymaral by 7.3 %, while the scarcity of vegetation increased by 12 %, it was observed that dense vegetation decreased by 3 % and moderate vegetation by 9.24 %.

Authors: Salari Estefanía , Franicevic Vladimir
Published: July 2024

The purpose of this study is to verify whether integrated information is being disclosed comprehensively in accordance with IIRC guidelines and whether this choice is subject to the influence of other variables, such as sector of activity, experience in preparing reports and the length of the reports. To carry out this analysis, a sample was examined consisting of 61 integrated reports prepared voluntarily by companies in South America that were available in the IIRC database as of April 1, 2022. Using a quantitative methodology, the main findings have been that the reports issued by the South American companies analyzed generally satisfy the content proposed by the IIRC (average level 61.68), however, some contents are not addressed in their entirety, so there are still aspects to strengthen and actions to improve . At the same time, it is highlighted that the level of content of the reports is linked to the sector of activity; companies in the financial sector have greater chances of having a higher level of information than those belonging to other sectors.

Por otra parte, se revisaron las principales políticas educativas dirigidas a reducir las desigualdades en las oportunidades educativas, algunas de las cuales se analizan en las experiencias recopiladas a través de entrevistas a diferentes actores educativos a lo largo del territorio, que dieron cuenta de los esfuerzos por transformar la educación en contextos altamente desiguales.
Derecho agrario: evolución, consolidación y perspectivas sobre la paz en Colombia
Authors: Bernal Ramírez Edwin Jesith , Rodríguez Beltrán William Ricardo , Panadero Dueñez Miguel Ángel
Published: July 2024

La presente obra estudia las reformas agrarias en Colombia desde el periodo 1936 a 2016, con el propósito de comprender las diversas dificultades y retos que enfrenta el sector agrario en el país. A su vez, analiza el componente agrario en el acuerdo suscrito en la Habana, entre el Gobierno de Colombia y las FARC, el cual ha implicado notables cambios en las políticas públicas, así como la creación de nuevas entidades estatales que sirvan como instrumento para la implementación de puntos centrales del acuerdo de paz, como el catastro integral y multipropósito, los Programas de Desarrollo con Enfoque Territorial (PDET) y los planes nacionales para la reforma rural integral. Por otra parte, el libro destaca el papel del campesinado en la lucha de sus derechos territoriales y el rol de las víctimas de despojo o abandono forzado de tierras en el marco de la justicia de transición establecido en la Ley 1448 de 2011, toda vez que es en el sector rural donde se ha exacerbado el conflicto armado interno y aún persiste en los territorios. En efecto, lamentablemente, en la actualidad han ocurrido asesinatos contra lideres sociales y reclamantes de tierras. Adicionalmente, se cuestiona la preponderancia que ha tenido, históricamente, en el ordenamiento jurídico, el derecho de propiedad respecto a otras formas de relacionamiento con la tierra, y se proponen elementos para una reforma rural que garantice efectivamente el acceso justo y democrático a la tierra, la salvaguarda de la soberanía alimentaria y la lucha contra la pobreza rural.

DEVELOPMENT AND SUPPORT OF A SUSTAINABLE: MARKETING PROVISION OF ENTERING STRATEGIES ON INTERNATIONAL MARKETS OF CHINESE COMPANIES: A CASE OF BYD AUTO
Authors: Hrinchenko Y. L.
Published: July 2024

The formation of powerful companies in the People's Republic of China that possess their own technologies and are able to offer a competitive product on global markets necessitated the formation of integral strategies for entering these markets. The implementation of such strategies requires an effective marketing strategy, one of the key elements of which is the formation of a sustainable brand.
Chinese manufacturers have traditionally relied on price advantages to gain a foothold in new markets, but this approach has proved ineffective in the case of high-tech products such as electric cars. Despite large investments, most companies from the PRC have not succeeded in forming a successful brand, so a study of the experience of the BYD AUTO company, which in a short time turned into the world's number one manufacturer of electric cars, reveals the conditions for implementing a successful international expansion strategy. The main challenge faced by the BYD AUTO company was the formation of a sustainable brand that would play a leading role in the promotion of products to international markets. Achieving this goal is facilitated by two key aspects of BYD AUTO's international marketing strategy: firstly, it is the brand's focus on the combination of technological advantages and social responsibility in the form of promoting solutions for transport with environmentally friendly electric motors, and secondly, the coordination of all elements of the marketing policy and orientation around them set of consumer requirements for the company's products and services.
Like most Chinese companies, BYD AUTO implemented a step-by-step strategy for entering foreign markets, adapting to the specifics of local markets. The main competitive advantages were the low price of the product and the involvement of a wide partner network from local companies through the financing of joint investment projects. To reorient the strategy to create a sustainable international brand, it is necessary to focus the brand on the company's key values, synchronize this positioning with the expansion of the product range, standardize the service and reconcile it not only to the field of sales, but also to further operation, intensify electronic sales channels, build an adaptive communication system with clients, which is able to maintain communication on a global level.

Published: July 2024

The study is devoted to the application of the method of surface hardening by friction Object of study - the process of surface hardening by friction.Subject of study - samples of 65G steel the method allows achieving high values of hardness, strength and wear resistance of materials in a short time and at much lower cost compared to other processing methods. The aim and objectives of the study are to investigate the nature of surface hardening of steel samples by friction. To achieve this goal, the following tasks are envisaged: manufacturing samples from 65G steel in the form of plates, preliminary heat treatment of samples  for their maximum thermal hardening, hardening of the surface of samples by friction, analysis of the microstructure and microhardness of each sample, comparison of the microstructure, microhardness and depth of hardening of these samples, conclusions on the  influence of processing factors on the  hardening result. Based on the  experimental data obtained, we  constructed graphs of microhardness  changes in the cross-section of the samples and studied the  microstructures. It can be seen that after friction treatment, a layer with a modified structure is formed in the surface of the samples. The  microhardness of the surface is significantly higher (approximately 2 times) than the microhardness of the main part in the samples. Metallographic analysis has shown that the layer formed in the samples has a martensitic structure characterized by a higher degree of dispersion and  microhardness compared to the martensitic structure obtained during the previous heat treatment. Changes in the microstructure and microhardness of the samples that were surface hardened using different processing modes were compared. Certain differences in the  characteristics of their hardened «white» layers were found. It is also shown that the hardened «white» layer  is located along the entire length of the surface in the samples and is  continuous and homogeneous.
DECISION-MAKING SUPPORT TECHNOLOGIES IN THE FORMATION OF QUALITY MANAGEMENT SYSTEMS AT VEHICLE REPAIR ENTERPRISES
Authors: Voloshin Dmytro , Voloshyna Liudmyla , Pleskach Oleksandr
Published: July 2024

In recent years, the strategy of creating a safely functioning and efficient transport complex of Ukraine integrated into the  world transport network has been fixed. Therefore, the creation of a progressive system of product quality management in the  conditions of car repair enterprises is considered an urgent scientific and technical task. The quality management system is a management subsystem of an industrial enterprise. Modern production systems are based on TQM principles and widely use  ISO 9001 certification. At the same time, certification is based on independent third-party audits (a conformity assessment  organization). The wide spread of the standard is based on the fact that it contains generalized  requirements (principles) for the  organization of product quality control, which can be used at enterprises that differ significantly both in terms of specialization  and the scale of production (depots or car repair plants). But this is the «bottleneck» of the standard – the lack of  consideration  of specialized production conditions makes it impossible to compensate for critical factors affecting the final quality of products. Currently, the accepted approaches to quality assessment do not fully take into account the factors that affect the final quality  of products. In order to put all market participants - railway operators, manufacturers, rolling stock repairers and suppliers in  mutually beneficial conditions, a single International Railway Industry Standard ISO / TS 22163 International Railway Industry  Standart (IRIS) was developed.For the effective use of tools for ensuring the quality of rail car repair, it is considered necessary to use modern management  decision support systems. They will allow real-time monitoring of production processes. It is possible to use the method of  fuzzy sets to improve the quality management systems of wagon repairs based on the development of separate control  algorithms with decision tables. In order to meet the requirements of international quality standards, it is necessary to significantly modernize management approaches based on the creation of progressive decision support systems.
AN EXPERIMENTAL STUDY OF THE EFFECT OF AN ADDITIONAL TANK ON THE DEFORMATION OF THE PNEUMATIC SPRING OF HIGH-SPEED RAILWAY ROLLING STOCK
Authors: Kuzyshyn A. , Kovalchuk V.
Published: July 2024

The use of a pneumatic spring suspension system in the second stage of spring suspension of high-speed rolling stock is an  integral component of ensuring its permissible dynamic indicators and traffic safety indicators. This work is aimed at  researching the deformation characteristics of the rubber-cord shell of the pneumatic spring in the vertical and horizontal  directions, taking into account manometric pressure, external load and an auxiliary reservoir. To achieve the goal, a  methodology for experimental studies of pneumatic spring deformation was developed using a test rig with an assembled  pneumatic spring suspension system, power and measuring equipment. Deformations of the rubber-cord sheath were  measured by analog sensors of linear displacements using an analog-to-digital converter and special software. It was  established that the effect of the auxiliary reservoir on the amount of vertical deformation of the lower part of the rubber-cord  shell does not exceed 3.46 %, which allows us to conclude that the auxiliary reservoir of the pneumatic spring suspension  system has a negligible effect on the vertical deformations of the lower part of the rubber-cord shell of the pneumatic spring. The dependences of the deformation of the rubber-cord shell of the pneumatic spring in the horizontal direction on the value of the manometric pressure when the auxiliary reservoir is connected and disconnected are obtained. It was established that in  the range of manometric pressure changes of 1.0÷2.5 atm the presence or absence of an auxiliary reservoir has little effect on  the amount of deformation of the rubber-cord sheath in the horizontal direction. However, at a pressure of more than 2.5 atm,  closing the tap to the auxiliary reservoir leads to significantly greater deformation of the rubber cord shell compared to the  deformation when the tap is open and the auxiliary reservoir is turned on. The obtained results regarding the deformation  characteristics of the rubber-cord shell of the pneumatic spring will allow us to proceed to the  study of the dynamic  characteristics of the pneumatic spring, which are necessary when establishing safe conditions for the operation of modern  high-speed rolling stock at the stage of its design.

The results of the study of the effectiveness of the search algorithm for selecting the maximum power from solar panels by a  step-up pulse semiconductor converter in the conditions of dynamic changes in illumination are presented. An analysis of the  mathematical model of solar panels was carried out, which determines the volt-ampere characteristics and power  characteristics of the solar panel as a function of its voltage. A search algorithm for determining the mode of operation of the semiconductor  converter, which ensures the mode of maximum power selection from solar panels, has been developed. This algorithm can be applied to various types of converters, in which the value of the input current depends on the filling  factor of pulse-width modulation. In the Matlab software, a corresponding simulation model of the DC-DC boost converter,  which selects the power of solar panels at different levels of solar radiation, was  developed, with the help of which the  efficiency of the developed algorithm was determined. In the course of the simulation, it was determined that the developed  algorithm provides a fairly high efficiency of solar panel power extraction, which is a fairly high indicator compared to the  described algorithms. It was determined that the dynamic properties of the semiconductor converter, which takes power from  solar panels, directly affects the time of transition to the mode of taking maximum power. During the first switch-on, the output  to the point of maximum power is about 1.2 seconds, in further  operation, the transition occurs almost instantaneously for a  time that corresponds to the time constant of the converter. Given that the processes of changing the level of sunlight take  minutes, this time is acceptable.

Authors: Bhagwan Bhavin , Pillay Manesh , Schutte Clara-Maria , Masenge Andries , Kakaza Mandisa
Published: July 2024

Background: Cerebral venous thrombosis (CVT) is an uncommon disorder accounting for approximately 1% of strokes worldwide There is a paucity of data regarding the association between an elevated factor VIII level and cerebral venous thrombosis (CVT).

Methods: From June 2015 to January 2022, patients with confirmed CVT on neuroimaging were identified at two public hospitals in South Africa. Their clinical presentation, radiological characteristics of thrombosis, and risk factors for CVT were analysed. Age-, sex-, and HIV status-matched controls were recruited. Factor VIII levels were analysed in patients with CVT and in controls.

Results: The study included 26 patients with CVT and 52 controls. The mean age was 40.3 and 41.4 years for the patients and controls, respectively. In the study group, 73% were females. An elevated factor VIII level (>150 IU/dL) was the most common risk factor, identified in 61.5% (16/26) of patients with CVT. The mean factor VIII level was significantly higher in patients with CVT compared to controls (200.1 vs 156.9, p = 0.017). An elevated factor VIII level (>200 IU/dL) increased the risk of CVT four-fold (age- and sex-adjusted OR: 4.437, 95% CI: 1.435–13.723, p = 0.009).

Conclusions: An elevated factor VIII level is a common risk factor for CVT; hence, investigation thereof should be included in the aetiological work-up. This study suggests that a higher cut-off value for factor VIII level increases the strength of the association with CVT.

Background: Papillomatosis is a skin condition that is distinguished by benign proliferative tumors with a complicated etiology and epithelial proliferation. There is a need to perform a more thorough study on bovine papillomavirus and identify the virological properties of the agent in detail since a definitive treatment approach against this infection has not yet been completely identified and the suggested treatment outcomes differ. Methods: Samples were collected from warts developing on the teats of 500 cattle raised for milk production in Burdur Center and its districts. The samples were defrosted in order to extract DNA and the Dneasy Blood and Tissue Kit was used for the extraction procedure. By using a PCR assay, wart sample extracts were examined for 13 different BPV types (excluding BPV Type 7). For BPV type-specific primers, a protocol was utilized. Amplification products were demonstrated using agarose gel electrophoresis. Result: In the PCR test of 500 wart samples, BPV types (type 1-type 13) were detected in 378 (75.6%). In the general distribution of BPV types (single or mixed types) in teat warts, BPV-2 (n=85; 22.49%), BPV-8 (n=45; 11.90%), BPV-9 (n=48; 12.70%) and BPV-10 (n=52; 13.76%) were determined to be more common. In the study; it was determined that three different combined treatments provided 100% regression or complete recovery in warts developing on the teat of cattle. In conclusion; one of these three treatment combinations may be preferred for teat wart lesions in cattle.

Background: Weed infestation is a primary cause of reduced yields, with estimated losses ranging from 10-70% due to crop-weed competition in Indian mustard. Therefore, it is essential to implement effective weed control measures to optimize the crop's yield potential. A combination of herbicides with manual, culturaland mechanical approaches is desirable to achieve optimal weed control. Therefore, a field experiment was carried out to evaluate the effect of integrated weed management on the productivity and profitability of Indian mustard. Methods: The experiment was conducted at the Agronomy Main Research Farm, College of Agriculture, Orissa University of Agriculture and Technology (OUAT), Bhubaneswar during rabi season of 2021-22 and 2022-23. It consisted of eight treatments in a randomized block design (RBD) with three replications. Result: Pendimethalin 0.75 kg ha-1 fb straw mulch 5 t ha-1 controlled the mixed flora of weeds which resulted in the lowest weed density, weed dry weight, weed index and highest weed control efficiency which resulted in the highest grain yield and stover yield of mustard. Pre-emergence application of pendimethalin 0.75 kg ha-1 fb straw mulch 5 t ha-1 registered the highest benefit-cost ratio.

Background: The fusarium wilt disease of chickpea leaves is a common illness that leads to economic problems for farmers due decreased crop yield. Early disease detection and the implementation of suitable precautions can help to increase the yield of chickpeas. This study offers an improved method for Fusarium wilt disease prediction based on severity level using a convolutional neural learning algorithm. Methods: The Convolutional Neural Network (CNN) model is utilized in this work to identify leaf disease due to wilting. The dataset contains 4,339 images of chickpea leaves that were obtained from Kaggle. After preprocessing, the data is sent into the network model for training. The model shows acceptable classification and accuracy metrics. Result: Deep learning methods are very useful tools for tracking leaf diseases at their early stages and can help farmers with the use of controlling methods. The proposed work looks for changes in the shape and color of chickpea leaves in order to predict severe fusarium disease. Training and validation accuracies show a balanced trade-off by giving satisfactory outcomes. The model shows an overall accuracy of 74.79%. The confusion matrix and classification parameters increase the model’s performance.

Published: July 2024

The Supreme Court has ruled that in contested divorce cases, women are entitled to receive nafkah iddah, mut'ah, and nafkah madhiyah, provided they do not act nusyuz. However, this provision is not being effectively implemented. This study examines the fulfilment of women's rights post-contested divorce in the Malang Regency Religious Court. The goal is to identify shortcomings in implementing these regulations and propose solutions for more effective enforcement. The research employs an empirical-juridical method, using secondary data from interviews and documentation with key personnel at the Malang District Religious Court. The qualitative analysis refers to Soekanto's theory. The Findings indicate that the fulfilment of women's rights in contested divorces at the Malang Regency Religious Court is ineffective. The law is clear and understandable, and officers, judges, and staff are accountable. Furthermore, the Malang District Religious Court provides sufficient infrastructure and support. However, the unmet factors—community awareness and cultural attitudes—pose significant barriers. Low legal awareness and compliance, coupled with cultural tendencies in Malang District to avoid legal processes and seek quick resolutions, hinder effective implementation. Addressing these issues is crucial for the regulations to achieve their intended impact on women's rights post-divorce.

The conception of a democratic rule of law in Indonesia has implications for the social and law order as a protection for the citizens. The protections guarantee the rights and responsibilities of every person regulated or protected by a democratic state. Either of the rights protected by the constitutions of Indonesia is guaranteed in obtaining and conveying information. As a profession, it is a part of journalistic activities, both professional and citizen journalism, as a constitutionally inherent right. The problem encountered is protection for citizen journalism, which is not regulated as protection for journalists in the legal system of the press. This research employed a qualitative model with a normative juridical approach to conceptualise the laws with facts and phenomena of journalistic activities. The analysis aims to assert that every person has a constitutional right to obtain and convey information like a professional journalist. A law is responsible for citizen journalism based on the law system of the press and code of ethics, which places citizen journalism products as a part of the news on press channels or press companies as the objects of the media that publish information. The concept of the principles of citizen journalism is related by maqashid shariah in Islam, which includes al-ahkam al-khamsah, namely religious protection (hifz al-din), protection of the soul (hifz al-nafs), protection of offspring (hifz al-nasl), protection of ideas/thoughts (hifz al-'aql), and protection of property (hifz al-mal).
