Social entrepreneurship, as a private form of business, is a growing phenomenon for Russia and requires additional analysis and study The social entrepreneurship in the agricultural sector of the economy at the national level is developing at a low pace and is still on a par with non-profit organizations and small and medium-sized businesses. In this regard, we can highlight the problems of its definition, representativeness and scaling Social entrepreneurship for the agricultural sector is not only an effective tool, but also represents an additional mechanism to state regulation. For the functioning of social entrepreneurship, it is necessary to ensure the economic and legal conditions for its conduct. Here, the issues of combining market and state regulators for the agro-industrial complex come to the fore. Assessing the effectiveness of the regulators makes it possible to draw a number of conclusions about the driving force for the development of social entrepreneurship in the agri-food sector. In order to achieve concrete results from the Institute of Social Entrepreneurship in the agri-food sphere, it is necessary to form a unified concept for the development of social business at the level of the regulatory framework, increase the state’s participation in financing social projects at the initial stages, and improve promotion and information tools. According to the results of the study, social entrepreneurs for the agricultural sector have the greatest difficulties with recruiting and creating conditions for novice entrepreneurs.

. In order to find reserves for optimizing production and management activities, the authors consider the possibility of reducing the costs of the enterprise by increasing the efficiency of the harvesting and transport complex, which is achieved by optimizing its composition. The essence of optimization is to organize the operation of equipment without downtime. In the article, the authors have proposed various mathematical dependencies for any agricultural organizations in order to select different types of vehicles, determining the required amount of these funds in the absence of the required number of basic cars. To substantiate the transport support, the values of the following indicators obtained as a result of time-lapse observation were taken: “vehicle waiting time” and “vehicle loading time” - for forage harvesters; “loading waiting time”, “vehicle loading time” - for vehicles. The necessary calculations were performed and the optimal composition of the harvesting and transport complex for the specified conditions was determined. The described methodology can be used in relation to various agricultural crops.
Introducing modern technologies to increase the economic efficiency of cocoa production in Africa
Authors:   Centre for Transition Economy Studies, Institute for African Studies of the Russian Academy of Sciences, Moscow, Russia, Gavrilova Nina G.
Published: January 2023

Global cocoa production has undergone significant changes over the past 60 years. The global volume of cultivation of this crop has grown significantly. The leading manufacturing countries in the industry have also switched their positions over the time. African countries, such as Ghana, Nigeria, Ivory Coast and Cameroon have significantly improved their results. At the same time, Ivory Coast steadily occupies the first place in this top for more than 40 years. To analyze the performance, two African states were selected – the first (Ivory Coast) and last (Cameroon) of the top ten. As a result, it was found that farmers in both countries have similar problems, regardless of the amount of cocoa produced. Almost all difficulties are associated with problems of maintaining tall cocoa trees due to difficult access, which significantly reduces the already unsatisfactory productivity of the sector. Another important problem in the selected African countries is the jobless youth employment; as young people don’t want put their life to work in backward agriculture. Despite the nominal increase of production volumes, the cocoa industry is undergoing a crisis, as its development follows an extensive path. Since cocoa is an indispensable product used in many fields, intensification plays a crucial role in the industry development. Therefore manufacturers have begun to use modern digital developments including hardware and software solutions more often. One of the decisions is to implement unmanned aerial vehicles (UAVs) in the cocoa industry to collect and process information (quality assessment of cocoa trees, terrain mapping, etc.), as well as to take care of cocoa trees (for example, for the precise application of chemical protection against pests and diseases). The article demonstrates the use of UAVs on the example of the cocoa sectors of Ivory Coast and Cameroon. Today, the latest technologies are still in the development and testing phase, so their large-scale application has not been implemented yet. However it is clear that innovations developed for the cocoa industry will not only increase production efficiency but also may attract young professionals to the sector. It is expected that these developments can be subsequently applied on a wider scale and will be used not only in the cocoa industry but in many other fields.

Published: January 2023

A conceptual modernized model of route planning during the voyage cycle of a sea vessel has been developed. It differs from the existing change in the method of planning the transition by trajectory points, taking into account the manoeuvrability characteristics, the water area for manoeuvring and the introduction of the stage "Risk Analyzer". Planning by the method of advanced content model and presentation of results by the summarized matrix of trajectory points (TP), after risk analysis, allows you to develop measures to manage the level of risks and maintain them at an acceptable level. As a result of accident studies in the areas of the Bug-Dnieper-Lyman Canal and Kherson Sea Canal and comparison with the Turkish Straits, it was found that navigation risk factors are the same – grounding, collisions in the canal, onslaught or other vessels, ice cases, technical reasons (failure of the main engine). Therefore, measures for voyage planning and preparation for navigational risk management will be the same for any region. The algorithm of planning by the method of the advanced content model allows the establishment of the cause of navigation risk and assumes the use of data for the vessel’s condition in real time. To reduce the risk of stranding, high-precision planning of trajectory points, automatic control of the amount of lateral displacement and the introduction of the correct reserve of water depth under the keel. Continuous automatic control of the bandwidth, by calculating the abscissa of the pole of rotation, prevents landing on the shoal and collision with the wall of the canal, fairway or ship at the berth. Keywords: vessel’s manoeuvrability characteristics, route planning by trajectory points, summarized matrix of voyage coordinates, navigational risks analyzer, acceptable risk management.

Authors: Konon V. , Savchuk V.
Published: January 2023

The given study focuses on the issue of marine fire safety systems as well as their improvement on container vessels. Modern technologies and a fresh look at the problem may significantly improve the methods and equipment for efficient and early reaction to hazardous situations’ development and/or their full prevention. In connection with the increase in the carrying capacity of container ships, the problem of the safe transportation of containers, and particularly the transportation of IMDG cargo, becomes more relevant. Therefore, in order to combine the advantages of existing fire protection systems with new perspectives in this regard, the concept of thermographic tools application was proposed, particularly for cargo carried under the deck. In the course of the work, the cargo state observations using a thermal camera were demonstrated. The preliminary effectiveness of the concept was evaluated, highlighting the importance of proper equipment calibration for more accurate results. To conduct an experimental assessment within the framework of the task, it was decided to use the simulation modelling methodology with the help of the designated integrated development environment (IDE) and C# programming language capabilities. The developed model gives an opportunity for further research in the field, describing the algorithm for processing the obtained data in order to comply with the framework of the main task. As such an algorithm, the use of a multilayer perceptron is proposed. Keywords: thermal imager, infrared thermography, fire safety, container transportation, neural networks, simulation modelling.
PROSPECTS FOR MODERN MARITIME EDUCATION AND TRAINING PRACTICES IN TERMS OF DISTANCE LEARNING
Authors:   National university ", Konon N. ,   Odessa maritime academy"
Published: January 2023

This paper considers the problem of maritime education and training of navigators in the context of modern distance learning conditions. The constant expansion of the world fleet in order to maintain productivity at a high level entails increased requirements for the qualifications and training of seafarers. In particular, for a correct assessment of the situation, the necessary condition is a combination of deep knowledge of the equipment operation and its practical significance, with proper bridge team management. According to statistics from open sources, the predominant cause of accidents sets on operators' actions or decisions. Thus, the technical skills and behavioural aspects of the navigation team have to be reviewed from an educational perspective. Concurrently, training efficiency can be increased by taking into account the limiting factors of the present day, which decrease the performance of classic methods of education. Curriculum priorities should be based on maritime accident data, and training methods should use modern technical means, expanding the boundaries of existing practices. On the other hand, in order to ensure complex preparation for navigational operations, it is useful to carry out training sessions with all parties involved. In addition, attention should be paid not only to the qualifications of merchant ships crews but also to the appropriate training of pilots and tug captains, since ignorance of the causes of loss of tug controllability and stability by any party may lead to an accident. Existing papers on classical and innovative tools and equipment used in MET (Maritime Education and Training) were analyzed, including the use of VR in the maritime education sector. A complex study of the problem includes a preliminary analysis of accidents, a review of modern methods used in MET, their limitations, and observations of educational practice at the National University “Odessa Maritime Academy”, including a questionnaire. The paper proposes possible prospects for the development and quality improvement of maritime education for navigators from the perspective of modern reality.

STUDY OF SEAKEEPING PERFORMANCE OF FISHING VESSELS WITH THE HELP OF CFD METHODS
Authors:   National university ", Pechenyuk A. ,   Odessa maritime academy"
Published: January 2023

Seakeeping performance is quite important for certain ship types. Fishing vessels often operate in areas with frequent storms, and sometimes it is necessary to continue fishing despite the worsening sea state. The development of hull forms providing good seakeeping performance of fishing vessels is the problem of current interest in ship design. The conventional approach to seakeeping studies is testing models in ship model basins. However, it is time-consuming and expensive, especially when many hull form variants are studied. For this reason, computer calculations based on the theory of ship motions and strip theory were developed and introduced. Today the more advanced methods of computational fluid dynamics (CFD) can be applied to the problem. The study of ship motions with the help of Reynolds-averaged Navier-Stokes (RANS) CFD method is considered in this paper. A suggested numerical model implies the generation of waves through initial and boundary conditions, which express fully developed waves with preset parameters. An object of research is the seagoing trawler with an overall length of 44.6 m. Three versions of hull form are used in simulations. All versions have similar transom afterbodies, but different forebodies: one similar to Axe Bow, a bulbous bow and one similar to X-bow. Ship movement with headings 180° and 150° at speed of 3.5 knots was studied to reveal differences in added resistance and ship motions. While added resistance and characteristics of heaving and pitching have shown no clear advantages among the considered shapes of forebodies, the version similar to X-bow has demonstrated a significant decrease in rolling at heading 150°. The results of the study have shown that the suggested numerical setup in combination with the CFD methods described can be used for quite realistic simulations of ship behaviour in rough seas. Keywords: seakeeping simulations, seakeeping of fishing vessels, CFD for ship design, improved seakeeping performance, simulation of ship motions.

Authors: Thatsanasuwan Natthaphon , Duangjai Acharaporn , Suttirak Pannatat , Phanthurat Naritsara
Published: January 2023

Background:Pasta is the world’s favourite food, except among those with celiac disease and other gluten sensitivities. Jackfruit seeds are a good source of nutrients and are gluten-free. Replacing wheat flour with jackfruit seeds in pasta represents a potential alternative food for those with gluten sensitivities. This investigation examined the impact of replacing wheat flour with jackfruit seeds on the proximate composition and sensory assessment of gluten-free fresh pasta (fettuccine). Methods:The pasta was prepared by replacing wheat flour with jackfruit seeds and adding 10% (percentage of rice flour [PJS] 10%), 15% (PJS 15%) or 20% (PJS 20%). The proximate composition and sensory attributes of the pastas were evaluated. Results:The proximate composition of pasta was significantly improved (p < 0.05) when the amount of jackfruit seeds added to the pasta was increased. Results showed decreased in energy (152-174 kcal/100g) and carbohydrate (8.2-14.8%), however increased in crude fiber (0.4–0.9%) and ash (1.9–4.7%). The results of a sensory characteristic evaluation with a nine-point hedonic scale showed that pasta made from 100% wheat flour was acceptable to the participants, and the gluten-free fresh pasta was not significantly different. The gluten-free pasta’s colour and texture changed as a result of adding rice flour and replacing the wheat flour with jackfruit seeds. The addition of jackfruit seeds resulted in a reduction in the flavour, cohesiveness, taste, and colour characteristics compared to wheat flour pasta. The pasta that substituted jackfruit seeds and added 15% rice flour scored highly on the sensory analysis. Conclusion:This study showed that fresh gluten-free pasta made from jackfruit seeds can be a tasty and nutritious substitute for regular pasta, with promising potential for food variety, notably for those with celiac disease.Clinical trial registration: TCTR20220325001Keywords:Gluten-free, jackfruit seed, just-about-right, nutrition, pasta

Published: January 2023

Several researches have been evaluating the use of nitrogen fertilization as a way to attenuate the effects of salinity in different cultures. However, plant responses to nitrogen fertilization under saline stress conditions are quite complex and many divergent results are still found in the literature. In some studies, the application of nitrogen attenuates the effects of salinity only under low salinity conditions, in others no significant interaction between salinity and nitrogen is observed and in some it is possible to observe some attenuating effect of nitrogen in plants under saline stress. In this context, this review discusses the possibility of nitrogen fertilization to attenuate the effects of irrigation water salinity in maize.

Published: January 2023

ABSTRACTObjective: To determine the quality of life among SARS-CoV-2 (COVID-19) positive patients with anosmia using the Short Version Questionnaire of Olfactory Disorders - Negative Statements translated in Filipino (sQOD-NS Ph).

Methods:

Design: Cross-Sectional Study

Setting: Tertiary Government Training Hospital

Participants: SARS-CoV-2 (COVID-19) RT-PCR positive patients aged 18 years old and above with COVID-19 symptoms and anosmia in a tertiary government hospital who consulted from March 2020 to August 2021 answered the short version of sQOD-NS Ph.

Results: Out of 108 participants with positive SARS-CoV-2 (COVID-19) RT-PCR test, 72 (66%) presented with anosmia, and sQOD-NS Ph scores ranged from 1 to 21 with a mean of 14.78. Thirty two (44%) encountered problems in eating while 21 (29%) had feelings of isolation due to loss of smell. There was an inverse correlation of -0.478 between recovery time of olfaction and QoL score, hence the longer the recovery time, the lower the QoL score, while the shorter the recovery time, the higher the QoL score (p < .0001).

Conclusion: Majority of COVID-19 patients with anosmia had mild or negligible impairment, while a small percentage had impaired quality of life. The low percentage may be due to high number of patients who may have recovered their sense of smell along the course of the disease.

Authors: Demchenko V. , Demchenko O.
Published: January 2023

For the preparation and during the execution of the work, experimental and theoretical studies were carried out on the influence of the state of the rolling surface profile of the wheelset on the level of interaction forces between the elements of the rail track and rolling stock in operation on the railways of Ukraine. Approaches to modeling the influence of the rolling surface profile of wheelsets on the stability of the wheelset movement and force interaction with the rail track were further developed. Experimental studies of the wear of the rolling surface of wheelsets of rolling stock were carried out, the intensity of their wear depending on the mileage of the locomotive was investigated. Studies of the influence of technical characteristics of hardness in the interaction of rail and wheel and their impact on the service life on the railways of Ukraine are analyzed. After the beginning of operation of wheelsets with increased hardness value, the optimal ratio of hardness of rail and wheel steel was violated. From various sources on the interaction of rails and wheels it is known that the best wear resistance in a friction pair is shown by metals with approximately the same hardness. Based on the data obtained, their analysis was carried out with the development of recommendations for further operation.

Published: January 2023

The article analyzes the impact of the environment on the load-bearing metal structures of passenger cars using the example of special-purpose cars based on the results of technical diagnostics in order to extend the service life.According to the results of the analysis, it was determined that despite the initial high characteristics of the load-bearing elements and the body shell, the very design of the passenger car body creates favorable conditions for the development of corrosion of the internal surfaces of the load-bearing elements. The analysis of the obtained results showed that the main operational damage to body elements can be divided into mechanical and corrosion. despite the initial high characteristics of the load-bearing elements of the structure and the shell of the body, the very design of the body of the passenger car creates favorable conditions for the development of the process of corrosion of the internal surfaces of the loadbearing elements. The bodies of wagons built in 1982-1990, which came for repair from most railways, were examined. For a long time, the author analyzed the technical condition of the bodies of passenger cars, technical diagnostics in order to extend the service life. Corrosion damage to the body of the passenger car was detected: the floor of the body, the belt of the lower lining, through-corrosion of the lining of the side walls). It was established that the rate of corrosion destruction increases from zero in the initial period of operation, when the protective properties of the anti-corrosion coating are effective, to 0,8 mm per year. Such a high intensity is explained by the specifics of the body design and the conditions of its operation.

The need for experimental validation of structural solutions concerning the frame of long-base flat wagon and assessment of the accuracy of theoretical calculations by carrying out resource cyclic fatigue tests based on the results of the recent studies analysis in the research of the strength of long-base flat wagons, was established. The methodology for carrying out resource cyclic fatigue tests of a long-base flat wagon is presented. The results of theoretical studies on determining the strength of a long-base flat wagon are described. The results of experimental studies of endurance cyclic fatigue tests of the frame of a long-wheelbase flat wagon before and after structural improvement are shown. Structural changes and improvements of the frame of the long-base flat wagon at the stage of experimental endurance cyclic fatigue tests are presented. The place of initiation and development of a crack in the structure of the frame of a long-base flat wagon is shown. Based on the results of the research, the actual strength of the elements of the wagon structure was determined and the design of the long-base flat wagon was chosen in order to prevent fatigue failure and ensure the required operational safety. The need to improve the evaluation methods of fatigue strength of welded joints of the long-wheelbase flat wagons frames at the design stage has been proven. The content of the article will contribute to the construction of new models of long-base flat wagons for mainline railway and the modernization of existing models, as well as to increase their strength and service life while in operation.
DEVELOPMENT OF THE PRINCIPLES OF BASALT FIBER MODIFICATION WITH THE PURPOSE OF INCREASING THE EFFICIENCY OF ITS APPLICATION IN TRANSPORT CONSTRUCTION
Authors: Doroshenko O.
Published: January 2023

The article examines the experimental and theoretical justification of the use of basalt fiber, as a promising material, with the help of which it is possible to obtain a new class of building materials. As a result, it was established that an increase in temperature contributes to an increase in alkali resistance of the fiber. The mass loss during aging in an alkaline solution after 28 days is about 5%, while the initial fiber loses more than 30% of the fiber mass during this time. A further increase in the temperature of isothermal aging is not effective due to a decrease in alkali resistance of the fibers and economic impracticability. To explain the processes occurring in the structure of the fiber during its heat treatment, X-ray images and spectra of the original and heat-treated fiber were obtained. In the process of heat treatment from 300 to 500 0С, the processes of defect healing, changes in the chemical composition and surface structure of the fibers occur as a result of Fe+2 → Fe+3 oxidation and the formation of iron oxide tetrahedra [FeO4]Na with the attraction of alkaline cations to the surface of the fibers. The expediency of thermal treatment of basalt fiber at a temperature of 500 0C is substantiated, which leads to compaction of the fiber structure and contributes to increasing its alkali resistance, which is confirmed by the morphostructural features of the surface of heat-treated basalt fiber aged in cement mortar.

The article presents the results of the development of a methodological approach to determining the components of the efficiency of the modernization of rolling stock using the example of the exploitation of bushing units with new generation bearings. Factors affecting the amount of additional capital costs for the modernization of electric trains with improved bushing units are analyzed. It is shown that additional capital investments arise due to the costs of research and development works, which are associated with the modernization of electric trains, as well as the costs of purchasing and equipping an electric train with new-generation bushing units instead of basic ones. It is proposed to adapt the calculation of the annual operating costs for the operation of the electric train to the conditions of the specific route served by it and to the existing system of maintaining the rolling stock in a technically sound condition. At the same time, the calculation of operational indicators of the use of the electric train on the route was performed. The influence of electric train modernization on the change in the annual operating costs of the suburban rail transport economy is analyzed. The average annual savings in operating costs for the repair and maintenance of the new generation of bogie assemblies per one electric train of the EPL9t series and the discounted economic effect of modernization for the remaining period of operation of the electric train were determined. It was established that the payback period for additional capital investments does not exceed 5.5 years. The proposed scientific and practical procedure for determining the components of efficiency allows to scientifically justify the feasibility of modernizing electric trains with new-generation bogies, taking into account the remaining period of their operation.
La gran deuda vigente de Ecuador: el caso Sarayaku
Authors: Veintimilla Quezada Silvia , Chacón Coronado Mary Elizabeth
Published: January 2023

El caso del pueblo Kichwa Sarayaku vs. Ecuador es uno de los más icónicos y reivindicatorios del Sistema Interamericano de Derechos Humanos en relación al reconocimiento de la vulneración de los derechos colectivos, específicamente el derecho a la consulta previa, libre e informada a los pueblos y comunidades indígenas sobre actividades que pongan en riesgo su vida o territorio. En este sentido el objeto de la presente investigación es exponer los motivos contextuales y jurídicos que llevaron a esta contienda internacional, para aportar en el debate jurídico que se desenvuelve en torno al incompleto cumplimiento de la sentencia emitida por la Corte Interamericana de Derechos Humanos (Corte IDH) reconociendo la responsabilidad internacional del Estado ecuatoriano. Para ello se ha desarrollado un análisis histórico-político sobre los antecedentes del caso para abordar con perspectiva crítica los puntos resolutivos de la sentencia emitida por la Corte IDH, que diez años después de su emisión no han sido ejecutados.Las dinámicas políticas, ideológicas y de preponderancia económica han dejado de lado elementos inherentes a la característica plurinacionalidad del Estado ecuatoriano, como la cosmovisión de los pueblos indígenas o la naturaleza como garantía de vida. La Corte Constitucional tiene la importante responsabilidad de establecer un precedente sobre la aplicación de estándares internacionales sobre protección de derechos humanos, que empresas petroleras como CGC no cumplieron.
Paridad de género y democracia: la integración de los Concejos Municipales
Authors: León Loza Mateo Javier
Published: January 2023

La paridad de género se considera el mecanismo jurídico de mayor importancia en defensa de la participación y representación política equitativa entre hombres y mujeres para la constitución de organismos públicos y decisorios de forma proporcional. El presente artículo se centra en el análisis de la incursión e impacto de la paridad de género en la legislación ecuatoriana y su repercusión en la estructuración de los organismos legislativos cantonales. Bajo una metodología cualitativa sobre el análisis y revisión documental se adopta el método inductivo, al describirse todos los fundamentos que sostienen el precepto de la paridad, como participación y representación política, igualdad formal, material y no discriminación, equidad y democracia. Se constata que la normativa jurídica defiende el ejercicio del sistema electoral bajo el principio de paridad de género, que configura el desarrollo de los diferentes procesos electorales con criterios de paridad, equidad, alternabilidad y secuencialidad que garantizan inclusión.Los concejos municipales son organismos legislativos cantonales que necesitan estar conformados por hombres y mujeres que representen a la población, para que en conjunto atiendan las necesidades e intereses de la sociedad; cuestión que se encuentra alejada de la realidad, ya que pese a la exigencia legal paritaria estos no se integran equitativamente, provocando una subrepresentación femenina y un debilitamiento democrático.
