Foot and Mouth Disease Outbreak in Indonesia: Summary and Implications
Authors: Chen Rosalie , Gardiner Evangeline , Quigley Ashley
Published: December 2022

This Watching Brief details a foot-and-mouth disease (FMD) outbreak in livestock in Indonesia. The outbreak, first reported in May 2022, is causing significant socioeconomic, animal health and biosecurity concerns in a country that has been FMD-free without vaccination since 1986. Delayed index case notification, difficulties with vaccination (e.g. accessibility issues, waning vaccine immunity and lack of cross-protection), limited understanding of persistent infection in carrier animals and lengthy restocking processes all present challenges for Indonesia in containing and recovering from this FMD outbreak. Thus, despite extensive research, the disease continues to present substantial challenges for outbreak prevention, surveillance and containment, which have important implications considering the widespread global prevalence of FMD and its impact on agriculture and trade in many countries. The socioeconomic burden of the current outbreak in Indonesia on individuals, households and communities is devastating, particularly in poor and rural areas. These impacts will likely continue after the outbreak is over, highlighting the need for co-ordinated support in strengthening outbreak detection and control in FMD-affected and other vulnerable areas.

Authors: Indraszczyk Arkadiusz
Published: December 2022

European Press was a periodical coming out in the years 1951–1980, published by the Central European Federal Youth Movement (since 1959 the Central European Federalists). It was an organisation of federalists-emigrants from Central European countries who considered it necessary to establish a Central European federation. Such a federation was supposed to be a way to improve the development of Central European countries and also a method to free them from the yoke of communists. European Press was a press organ which propagated this idea. The information contained in the journal remains valid today, especially in relation to the ideological layer of European integration and its political and social foundations.
Life Changes in Family and Productive Activities among Older Adults: Focusing on Economic Activities
Authors:   Korea Gerontological Society, Choi Ji-Young
Published: December 2022

The importance of productive activities and roles in society of older adults has been recognized in the contemporary aging societies. Although existing studies have revealed that individual human capital is an important factor in the productive participation of the elderly, the influence of the family has not been systematically considered. Using data from the 2th to 6th wave of Korean Longitudinal Study of Ageing(KLoSA), this study examined the effect of the individual and family characteristics on economic activities among older adults. The results are as follows. First, as a result of analyzing all the elderly, only individual human capital characteristics had a significant effect on participation in economic activities. Second, as a result of analyzing male and female older adults separately, it was confirmed that individual characteristics and family characteristics had a significant effect on participation in economic activities. In particular, children's participation in the labor market related to the life changes of family members was an important factor influencing the economic activities of the elderly. Third, when transitioning from a state with some or all children not participating in the labor market to a state with all children participating in the labor market, it was found that male seniors are less likely to participate in economic activities while female seniors are more likely to participate in economic activities. Based on these research results, academic and policy implications were discussed.
Political wisdom of the Kajang "Ammatoa" indigenous community in South Sulawesi
Authors: Latief Iqbal , Syam Ridwan
Published: December 2022

Democracy, which is implemented in Indonesia through general elections (Elections), places the community as a whole as the holder of people's sovereignty.  This is guaranteed in the 1945 Constitution of the Republic of Indonesia (UUD).  However, the implementation of people's sovereignty is still a problem, because there is still a low understanding of the people's sovereignty that they have, especially in elections.  One component of society that also has political sovereignty is indigenous communities, especially in South Sulawesi, namely the Kajang "Ammatoa" indigenous community. Therefore, this study examines the meaning of political sovereignty in the Kajang indigenous community "Ammatoa" and the local wisdom owned and implemented in the 2019 elections, including the 2020 Regional Head Election (Pilkada) in Bulukumba Regency. The method used is descriptive qualitative, and the processed data is primary and secondary. This research begins with the identification and formulation of problems, data collection, data processing, and analysis, including data classification and reduction, drawing conclusions, and verification. The results of this study; (1) Although the Kajang indigenous community is closed, the application of democratic values has been realized for a long time and has become its main local wisdom in choosing leaders called "ammatoa" (traditional chairmen). That is, "ammatoa" is democratically elected and not because of the principle of blood or hereditary ties (traditional leadership); (2) The meaning of democracy and political wisdom, also expressed in elections and regional elections, "ammatoa" as a leader gives freedom to its citizens to choose according to their beliefs without any intervention. So, even though there are "ammatoa" children who became Caleg in the 2019 elections, they were not elected; (3) responsibility as a citizen is also evident in the high level of participation of the Kajang indigenous community in elections and regional elections, even though initially there were cultural and administrative obstacles. This proves that the Kajang indigenous community has practiced the meaning of popular sovereignty for a long time and has become a form of political wisdom. As a suggestion, it is necessary to make a follow-up study that captures the meaning of people's sovereignty in other indigenous communities as a reference in formulating inclusive election policies in Indonesia.

Authors: Bettini Giordana , Saia Giorgia , Franco Piero , Valsecchi Stefano , Tognin Laura , Alexandre Enrico , Bedogni Alberto
Published: December 2022

Background: Currently, the standard design of the skin component of abdominal soft-tissue flaps recommended for head and neck reconstruction encompasses the upper and lower periumbilical region to include the maximum number of myocutaneous perforators. Yet, this flap design precludes the harvest of bilateral flaps and the use of the contralateral area in case of flap failure. Aim: We aimed at proving the long-term safety of infraumbilical abdominal free flaps in terms of abdominal wall integrity. 

Methods: Consecutive subjects who underwent reconstruction of composite cervico-facial defects with infraumbilical free flaps between 2008 - 2020 were enrolled. After surgery, patients were followed up at three-month intervals to evaluate the incidence of any complications at the donor site. 

Results: 25 patients underwent reconstruction with free flaps from the lower abdomen. A total of 35 abdominal flaps were performed; ten patients underwent bilateral flap harvest. Marginal abdominal skin necrosis occurred in 3 patients. Abdominal bulge occurred in one case; neither hernia nor abdominal wall weakness was encountered at a median follow-up of 12 months. Conclusions: The infraumbilical region is a safe donor area of free flaps for head and neck reconstruction that preserves abdominal wall firmness and provides a satisfactory cosmetic result at the donor site.

Authors: Velikanova Irina
Published: December 2022

Abstract. The article reflects the problems of stimulating the development and implementation of advanced technologies in the field of agro-industrial production in general and in flax growing in particular. The mechanism is proposed, which is based on the use of the entire complex of financial, credit, economic, investment, tax and other instruments of influence on the activation of demand for scientific and technical products with a direct mechanism of state regulation and support. Relevance. One of the problems of the development of the agro-industrial complex is the existing model of the functioning of the economy, in which there are no sufficiently effective incentives for private capital investment in the acquisition of advanced developments in agricultural and agro-industrial production. The justification and application of a financial and economic mechanism to stimulate the introduction of innovative technologies in flax production has now become simply necessary to ensure technical and technological modernization at the expense of domestic developments of research centers and private companies, which is due to the sanctions imposed against our country and the growth of international tension. The problem of finding a mechanism to stimulate the allocation of long-term funds for the acquisition of advanced technologies is becoming particularly relevant. The purpose of this study is to propose a financial and economic mechanism to stimulate the introduction of advanced technologies in the flax industry of the agro–industrial complex of Russia, the tools of which will increase the level of innovation activity of economic entities of the flax complex. Methods. In the course of the study, methods of comparative, abstract-logical, functional-cost analysis, expert evaluation were used. Results. The article proposes a financial and economic mechanism to stimulate the introduction of advanced technologies, the tools of which will significantly increase the level of innovation activity of economic entities of the flax-growing subcomplex. In addition, the use of the mechanism of interaction between development institutes (VEB) and endowment funds proposed for use in industry science creates prerequisites for expanding the financing of research developments in flax production. The scientific novelty is in the proposal and justification of a new option for the interaction of development institutions within the financial and economic mechanism for stimulating the development and implementation of innovations in the agro-industrial complex (flax industry).

The purpose of the work is to study of options for thermal modernization of enclosing structures with a justification of the optimal composition of energy-saving measures to achieve maximum energy efficiency of buildings. Ukraine's energy balance shows that more than 30% of the total energy is consumed by the residential sector, of which up to 80% goes to heating. This is due to the low level of energy efficiency of the enclosing structures of residential buildings, as well as the unsatisfactory technical condition of utilities, due to physical wear and tear and obsolescence. The peculiarities of the influence of the type of thermal insulation materials and their characteristics on the thermal and energy performance of the building are investigated. It was found that the increase in the density of insulation affects the thermal resistance of walls in different ways - the density of mineral wool and extruded polystyrene have the opposite effect of foamed polystyrene, ie insulation of mineral wool or extruded polystyrene should be chosen with the lowest density Element-by-element analysis of the components of enclosing structures proved that their impact differs significantly, in the case of separate implementation of measures can reduce heat consumption by 0.07… 23%, and the priority is to modernize the walls of building facades (provided that the glazing ratio K ≤ 0 , 25). Measures of complex thermal modernization of enclosing structures are substantiated by the method of expert assessments according to technical-energy, financial and ecological criteria. Calculations confirm that the complex thermal modernization will reduce the value of specific energy consumption and specific greenhouse gas emissions by 1.5 times, specific heat consumption - by 1.9 times, increase the energy efficiency class of the building from G to D. It is shown that the normative values of heat transfer resistances of external enclosing structures will provide only the class D energy efficiency of the building. It is not possible to achieve the recommended class "C" and higher by further increasing the thermal resistance of the enclosing structures - it is necessary to modernize the engineering systems of the building.
Concrete Corrosion of the Above-water Part of the Oil Trap in the Water Management of Oil-and-gas Facilities
Authors:   Kharkiv National University of Civil Engineering and Architecture, Sierohlazov Volodymyr
Published: December 2022

The purpose of the work is to identify the type and kinetic indicators of concrete corrosion of the surface part of the oil trap in the water management of oil-and-gas facilities. Biogenic sulfuric acid concrete corrosion is a constant risk for water management facilities, in which hydrogen sulfide and its derivatives are present in the operating environment. Based on the analysis of the cycle of the oil production enterprise, the above processes are inherent in the water management of oil-and-gas facilities. The presence of hydrogen sulfide in water operating environments indicates a very high probability of the development of biogenic sulfuric acid aggression in the above-water moistened part of the structure - the influence of sulfuric acid produced by thion bacteria. An attractive environment for the accumulation of hydrogen sulfide by microbiological sulfate reduction is reservoir water at oil production sites, especially at water management sites where long-term sedimentation occurs. About 80% of losses from corrosion of oil industry equipment are associated with the activity of sulfate-reducing bacteria. In the experimental studies, concrete samples were studied, which were taken from the upper surface of the oil traps at the studied oil production facility located in the Dnipro-Donetsk depression. The results of a chemical study of concrete samples (decrease in pH, accumulation of sulfur compounds, and leaching of calcium compounds) indicated that the concrete is affected by biogenic sulfuric acid aggression. The experimentally determined dynamics of calcium compounds in the studied concrete samples indicated its leaching by aggressive sulfuric acid: the lower the pH of concrete, the lower the concentration of total calcium and the higher the concentration of mobile calcium. Based on data determined using a concrete corrosionmeter, the rate of microbiological corrosion of concrete was calculated - up to 0.08 mm/year, and the depth of diffusion of biogenic acids - up to 1.9 mm. The calculated average annual concentration of hydrogen sulfide in the atmosphere affecting concrete was 3.4 - 5.4 mg/m3, which exceeds the MPC of the working zone in the oil and gas industry.

The purpose of the work is the theoretical substantiation of the operating modes of the parts of a typical parallelogram mechanism, the determination of the magnitude of the initial deformations and the optimal operating modes of the parts made of polymer-composite materials. Changes in the geometric dimensions of parts of the sowing section under the influence of loads during operation are considered. Determination of the load acting in the tribo couplings of the sowing section of the "Turbosem II 19-60" complex. The mathematical model for determining radial, angular displacements and the magnitude of deformations due to design features and loads on movable couplings is substantiated. The methodology for determining the maximum and minimum compensation of installation deformations for parts made of polymer-composite materials is proposed. Experimental studies have established that the rate of wear (0.003 g/h) of PCM parts has a linear dependence on working life, which allows predicting the resource of tribo couplers. Taking into account the geometric dimensions of the PCM part and the limit value of the gap in the tribo-coupling, it is possible to determine the resource of the moving tribo-coupling with high probability. The obtained linear function of the dependence of the amount of wear on the working life is valid for the material UPA-6-30, under the condition of a linear sliding speed of up to 0.1 m/s and a load on the tribo coupler up to 600 N. Experimental studies have determined the optimal values of the load value - 250 N and the gap - 300 μm in the tribo coupling "polymer composite - steel". The obtained results can be used in the modernization of existing or development of new designs of sowing sections.

A developed transport system is an important condition for the social and economic growth of the state, maintaining the competitiveness of the national economy and high standards of the quality of life of the country's population. Numerous scientific works have analyzed both the essence of the transport system and individual components of the latter - railway, road, water, pipeline, and air transport. The article analyzes the state and problems of the development of the transport sector, indicators of freight and passenger traffic on road transport. The transport industry of Ukraine is studied through the prism of fulfilling the social function of the state. The set of advantages of road transport in the social sphere is substantiated, in particular: actual social, socio-economic, ecologically oriented technical-technological, regulatory and legal advantages. Ways to reveal the potential in the transport industry of Ukraine are proposed. Considerable attention is paid to approaches to management and administration in improving the social function of the transport industry of Ukraine. It is proposed to improve the transport industry by modernizing public management mechanisms for supporting the domestic road transport industry. Targeted programs for the development of the transport system ensure technologically balanced and ecologically oriented development of both the industry and the state as a whole. The future of the Ukrainian state and the well-being of its citizens depend on the efficiency and development of the transport system.

Aluminum alloys are widely used in industry. Recently, they are used as a replacement for steel for the manufacture of pulleys, gears, columns of hydraulic rotary transmissions of grabs, etc. This reduces the weight of the parts and reduces carbon emissions into the atmosphere. However, aluminum alloys have low abrasive wear resistance, so their use is possible with coatings on the surface. High-speed gas flame spraying (HVOF) was carried out on the equipment (Diamond Jet Hybrid gun). Arc coatings with a thickness of 500 µm were applied using FMI metallizer and FMI-2 powder wire (Cr6Al6B3Fe-base). PEO (oxido ceramic) coatings were synthesized on D16T aluminum alloy in an electrolyte of 3 g/l KOH + 2 g/l liquid glass (sodium silicate) with a pulsed current at a frequency of 50 Hz, with the ratio of the densities of the cathode and anode currents Jc/Ja+15/15 A /dm2. The duration of the PEO process is 60 min. The open porosity of the coatings was determined by the method of hydrostatic weighing. The phase composition of the surface layers was studied using a DRON-3.0 diffractometer. HVOF (VC) and PEO coatings have been found to have 3 to 4 times higher wear resistance than high carbon hardened steel 100Cr6 and 2 times higher than galvanic chromium coatings, but have high energy consumption. Two methods have the lowest energy consumption: electric arc spraying of coatings and hard anodizing. At the same time, the wear resistance of such coatings is significantly lower than that of coatings obtained by the PEO and HVOF (VC) methods. For the restoration of worn parts, the most appropriate methods are HVOF (VC) and electric arc spraying, as they allow applying thick coatings up to 5 mm. Conclusions: It was established that the studied HVOF (VC), PEO, EDP and hard anodized coatings significantly increase the abrasive wear resistance of aluminum alloy parts. HVOF (VC) and electric arc spraying methods can be used to protect new and worn parts from wear. PEO and hard anodizing methods can be used to protect against wear on new parts only. The use of these methods increases the wear resistance of parts made of aluminum alloys to the level of steel and allows replacing steel and cast iron with aluminum alloys with coatings, reducing the weight of parts and carbon emissions into the atmosphere.

The analysis of the state of development and use of machine learning algorithmic models in road transport logistics systems has been carried out. The expediency of application of machine learning algorithmic model for predicting fuel consumption by vehicles during the grain crops delivery from agricultural enterprises to the grain elevator has been substantiated. The reggression machine learning algorithmic models: DT (Decision Tree) model and the RF (Random Forest) model for forecasting fuel consumption by vehicles is selected. On the basis of historical data of the enterprise that transports grain crops from agricultural enterprises to the elevator, forecasting of fuel consumption by vehicles with the use proposed models has been carried out. The resulting prediction of vehicle fuel consumption with the use the RF random forest model, as opposed to the values of individual decision trees, has a lower ability to retraining and greater flexibility to the limit of vehicle fuel consumption decisions. Evaluation of the specified models for forecasting fuel consumption by vehicles during the grain crops delivery from agricultural enterprises to the grain elevator has been performed according the following criteria: mean absolute error (MAE), root mean square error (RMSE), Total time and Training time. It has been determined that the best prediction of fuel consumption by vehicles during the grain crops delivery from agricultural enterprises to the grain elevator is performed by the RF random forest model, which provides a relative error of the obtained results of 4.6% with a standard deviation of ±0.1 and a total machine learning time of 4.8s. The obtained results of the researches can be used for the selection of the most efficient means of transport for executing orders of the grain crops delivery from agricultural enterprises to the elevator.

Crossing – is a place of crisscrossing, fitting closely or branching of roads at one level the limit of that are imaginary lines between beginning of rounding of edges of travel part each of roads. It is the critical place of road net from the point of view of carrying capacity of transport, level of service and safety, especially in case of location with near railway ways. The successful planning or reconstruction of crossing must answer all aims of mobility and safety, and also possibilities of improvement of public space. The article is devoted to the study of safe driving conditions of the intersection with nearby railway tracks for the city of Dubno, Ukraine. At the investigated intersection, from the point of view of the traffic safety organization, the following traffic situations are observed: difficult exit; non-observance of the turning trajectory of vehicles due to the overall characteristics of the transport or the selection of an insufficient trajectory for changing the direction of movement; selection of insufficient rounding radius for right turn; the difficulty of making a left turn at a prohibited railway crossing signal. With the increase in the duration of the prohibited traffic light signal, there is an increase in the number of vehicles, especially cargo vehicles, the total length of which can reach more than 200 meters. The width of the road is not enough to overtake vehicles. In order to simulate different conditions of crossing the intersection and make the necessary decision, the composition and intensity of traffic flows were studied. The study of traffic flows was carried out in the period from August 15 to 21, 2022. A simulation model of the road situation was built and the actual conditions for safe passage of an intersection with nearby railway tracks were, and practical recommendations were given to improve the organization of road traffic. It has been established that in order to increase the safety of passing through an intersection with nearby railway tracks for the city of Dubno, based on the conducted research and simulation modeling, it is necessary to provide an additional traffic lane for vehicles to make a left; a pedestrian crossing through the intersection; increase the width of the traffic lane.

The problem of ensuring the safety of movement on the Cherkasy region roads is being studied. The need to improve transportation safety and study the factors affecting it arose with the development of market-based methods of transport management, changes in the structure and management system of the transport industry of Ukraine. Such qualitative changes have led to the development in this field of new models, methods, methodologies of transportation safety management capable of comprehensively solving the problems of transportation organization, their legal, financial, and information support. In order to identify methods of improving road safety in the region, an in-depth analysis of the state of accidents in the territory of the General Directorate of the National Police in Cherkasy Region was conducted by types, causes, days of the week, time of traffic accidents, number of victims, number of dead, etc. Dangerous sections of highways were identified and an experimental study was conducted to identify the causes of traffic accidents. In the course of the experimental study, measurements were made that allow to calculate the speed of vehicles that, violating traffic rules, were overtaking on sections of highways with blind turns. From the obtained results, it can be concluded that the main causes of traffic accidents are the violation of traffic rules, which is caused by the difference in traffic speeds in the flow and the unconscious attitude of drivers to the corresponding traffic situation. As a result of the conducted research, recommendations were provided for optimizing the organization of traffic on dangerous sections of highways. Namely, it is proposed to use the methodology of experimental research on other dangerous sections of the country's highways and to install dynamic traffic signs that will allow regulating the maximum permissible speed depending on the selected factors on the relevant sections, thereby reducing the speed difference in the flow of traffic and punishing violators for exceeding the speed limit. In addition, a very important element of improving safety on the country's highways is the dissemination of information programs on compliance with traffic rules among the country's youth. The proposed method is recommended to be used to reduce the number of road accidents, and accordingly, to reduce the number of victims of road accidents in the territory of Ukraine.

The article considers the problem of increasing the reliability of machines and the efficiency of their use when transporting agricultural products. Increasing the reliability of machines at agro-industrial production enterprises is considered on the basis of improving the strategy of their technical maintenance and repair. At the same time, logistic service methods are used to provide the fleet of cars with the necessary spare parts. The theoretical justification of the formation of the composition of spare parts at the enterprise, its limitations and the supply system is given. It is noted that in the processes of providing the necessary spare parts, the logistics center takes control. The main factors affecting the efficiency of spare parts supply organization have been identified. On the basis of the cost function, optimal management based on logistic models is considered. Comparative analysis proved the advantage of the developed system of technical maintenance and repair along with the existing planned preventive system. This is, first of all, an increase in the probability of trouble-free operation and the availability ratio of KamAZ vehicles and mobile agricultural and mobile agricultural machinery of the John Deere family.
