Authors:   Mykolayiv National Agrarian University, Mykolaiv, Ukraine, Kim Nataliia
Published: October 2021

The purpose of the article is to study the patterns of evaluation of quality indicators of the technological process on a sizeless scale. The quality of production depends on the quality of technological processes, namely - many factors of technological, technical and organizational nature. The technological process is the basis of any production process, is the most important part of it, associated with the processing of raw materials and its transformation into finished products. Product quality is the most important indicator of companies seeking to develop and succeed in competition among other manufacturers. This issue is especially relevant for Ukrainian companies seeking to be competitive in the European and world markets. To manage the quality of the object often have to use statistical methods of evaluation and management, where, as basic information you need to know not the law of distribution of quality in its units, and know the law of distribution of their assessments on a sizeless scale, therefore, research related to determining the patterns of distribution of assessments of quality indicators of the technological process on a sizeless scale. Knowing the law of distribution of unit quality indicators of the object of qualimetry and knowing the dependence with their estimates on a sizeless scale, it is possible to solve practical problems to determine the probability of getting estimates of quality indicators in a given interval. The solution of such problems is relevant in determining the risks of the processes of quality management systems, or determining the reliability of the technological process and other indicators. As a result of the study, the main conditions for the quantity and quality of statistical information were identified. It is shown that the correctness and efficiency of solving practical problems, using statistical methods of quality assessment, is determined by the amount of information about the functioning of the technological process, which can be divided into conservative and operational. Conservative information includes knowledge of the distribution law and finding effective statistical estimates of its parameters, and operational - the sample size.

The article briefly describes the processes carried out during the operation of the gas hydrate accumulator (GHA) at the automobile gas-filling compressor station (AGCS): formation of natural gas hydrates, their accumulation and storage, and melting with the release of natural gas at high-pressure р = 25MPa, sufficient for full refueling gas cylinders. The circuit-constructive solution of filling with compressed natural gas in AGCS-GHA is offered, and the principle of its work is described in a good example. It is shown that during AGCS-GHA operation with four compression stages and ACG compressed gas accumulators, the gas from GHA to ASG moves in the connecting pipeline at adiabatic conditions at subcritical speed, i.e., below the speed of sound, because the pressure ratio рASG / рGHA coefficient is more critical. Calculations performed for these conditions by thermodynamic equations of gas flow in the subcritical mode of motion, without losses, showed that the velocity in a pipe with a diameter of d = 15 mm has a value of w = 793 m / s. This will ensure a specific gas supply from GHA to ASG at the level of m = 0.178 kg / s. It is proposed to use the coefficient efficiency of refueling to characterize the energy efficiency of refueling vehicles with compressed natural gas in AGCS-GHA. According to the results of calculations, it is evident that the energy efficiency of refueling vehicles with compressed natural gas in AGCS-GHA is 6% higher than in traditional AGCS at the same conditions: the corresponding values of coefficient refueling efficiency = 0.47 and = 0.41. The article also illustrates that in the process of melting gas hydrates in GHA at a temperature of t = 26-28 0C, one can get compressed natural gas at a pressure of р = 30-35 MPa, which will use AGCS-GHA without additional compressor equipment for refueling mobile gas stations (PAGZ), in which the optimal values of the maximum pressure are in the range of 32-35 MPa.

The paper aimed at assessing the scenarios for transport systems sustainable development under car-oriented society. As SUMP supposes limitation in private cars usage, we focused within this study on assessing the direct and indirect effects due to sustainable measures deployment in a case of car-based mobility. Also, we proposed a new option to determine the number of cars origin from the transport zones using GIS-based data. To achieve the major aims of this study we conducted the experimental research on urban mobility when people tend to use the private cars instead of public transit. The simulation has been conducted with PTV Visum software. Brovary city has been chosen as a case study to reveal the advantages and disadvantages of the car-oriented mobility. We developed two alternative scenarios considering the total ban for entering the city center by the private cars and soft conditions when the cars can cross the city center but with speed restriction. Besides that, both scenarios supposed the changes in traffic organization, namely the revers movement introduction. As the results we revealed the reduction in travel times for both scenarios, but the average travel distance has increased for scenario with ban for entering the city center by the cars. As for the second scenario with soft restrictions it allowed to reduce the travel time, travel distance and increase the traffic speed. But the indirect effect reflected by the CO2 emissions reduction has not changed significantly. Based on these results we can state that sustainable measures in a case of car-oriented mobility can provide only the direct effect for car users. The indirect effect remains quite low allowing to conclude that sustainable development should be grounded on TOD and non-motorized modes.

An approach to determining the efficiency of the operation in transport systems, which is a measure of compliance with the actual result of operations desired, and therefore is a measure of guarantee or probability that the service life of the transport service will be no less than necessary. The algorithm of its definition is given and the functions of distribution of result of operation are graphically represented, schemes of estimation of probabilistic guarantee are shown. The list of requirements which the indicator of efficiency and forms of its measurement should satisfy is considered. It was found that in the study of the effectiveness of operations is a common indicator of the average result, which is used in cases where the purpose of the operation is expressed by a numerical variable. It was found that an important property of the indicator of the average result is its additivity, and the increase in the quantitative indicator of periodicity leads to a decrease in the quality of the transport system and failure to fulfill the property of additivity. It is proposed as a result of the operation to increase the reliability of the transport system to assume that the period of its trouble-free operation was not less than the period of time of active operation of this system. The principles of using the scattering characteristic of a real result relative to the required value or mathematical expectation as an indicator of efficiency under the conditions of describing the result by a random variable are given. A graphical illustration of the matching functions with respect to the scattering indices of the result is given. It is found that the period of trouble-free operation of the transport system and the period of time of active work can be random, ie the desired result in these conditions is described by a random variable, which is usually the minimum required result. Forms of efficiency indicators and compliance functions are given. It was found that the performance indicator for these situations includes partial indicators. With any strategy of the opponent and the fixed strategy of the decision-maker, the efficiency of the operation will be less than the mathematical expectation of the correspondence function. Thus, the mathematical expectation of the correspondence function is the lower limit of the average value of the correspondence function of the actual result of the operation required for the decision maker.

The article considers the problems of distributed computing and possible ways to solve them. With the beginning of the development of computer networks and the advent of the Internet, a large number of remote services have appeared that offer their available computing resources. On the one hand, as a result of such cooperation, it is possible to solve the problem of insufficiency of own hardware resources, but, on the other hand, there are a number of problems, namely: lack of standards and algorithms of development and modeling as the main means of building distributed computing systems; lack of universal and convenient application development tools; technical problems and limitations, which are determined by the currently existing technical solutions for the construction of data processing systems with relatively high performance; small number and narrow focus of tasks that could generate income and require a comprehensive solution. One of the main problems with distributed computing is the slow development of high-speed network equipment that could compete with internal connections. Increasing the data transfer rate using outdated technologies is impossible for a number of technological and physical reasons. Research in the field of development of new data transmission protocols and their optimization is carried out, but the final decision does not yet exist When organizing calculations related to data processing, an important issue is the rational distribution of data in terms of effective problem solving. Ordinary users do not do this, because most often they use ready-made solutions for their tasks. Even when creating new distributed systems by professional programmers, the specifics of application areas are not fully taken into account. That is, the created software products do not provide the ability to adapt to specific tasks of users, although work in this direction has significantly intensified. The solution to the problems of universality of the application of distributed computing lies in the creation of methods for software development and the creation of generalized solutions that would be universal and suitable for use in various fields of research.

The aim of the study. By introducing strong oxidizers to the electrolyte form anode layers on the surface of aluminum with increased mechanical characteristics. To determine the effect of the duration of the formation of an anode layer to change its properties. Hard anodizing was performed at a temperature of –4...0C for 60 min. A 20% aqueous solution of H2SO4 was used as the base electrolyte. During anodizing, the current density was 5 A/dm2. To determine the effect of strong oxidants on the characteristics of the anode layers (oxide), 30 were added to the electrolyte; 50; 70 and 100 г/лof hydrogen peroxide (H2O2). In some cases, it was purged with an ozone-air mixture at a rate of 5 mgmin/l of ozone. It was found that the oxide layer (Al2O3H2O) during hard anodizing on aluminium alloys forms not only oxygen ions, which are formed by the decomposition of water, but also neutral oxygen atoms, which are formed by the decomposition of hydrogen peroxide and ozone. It was found that hydrogen peroxide, as well as blowing the electrolyte with an air-ozone mixture increase the thickness and microhardness of the anodized layer by 50% due to the reduction of the number of water molecules in alumina by half. Hydrogen peroxide and ozone apparently also reduce the thickness of the barrier layer of the coating, through which oxygen and aluminium ions penetrate and which, when combined, form an oxide layer. Conclusions. 1. It has been established that aluminum anodizing for 60 minutes. provides an increase in its properties. Changing the composition of the electrolyte contributes to the growth of microhardness in 1.2 ... 1.7 times. The resistance of abrasive wear increases with the content of different amounts of applications in the electrolyte and the maximum is at 30 g / l H2O2. Blowing the base electrolyte ozone provides an increase in the microhardness of the layer from 380 to 510 HV. The higher loss of mass for higher microhardness is caused by an increase in porosity of coatings. 2. It is determined that an increase in the anodization time in the baseline electrolyte to 120 and 180 minutes contributes to the growth of microhardness to 640 HV compared to an anodized layer for 60 minutes. Loss of mass in the study of abrasive wear is less than 3-4 times with longer anodation than at 60 minutes in the baseline electrolyte.

Background: Alcohol intoxication is among the leading and preventable causes of death, disability, and injury in numerous societies. Ethanol and methanol are the most commonly used types of alcohol. Increasing nurses’ awareness about the difference between intoxication with these two alcohol types will prevent the occurrence of dangerous and deadly complications of intoxication. We investigated the awareness of the nurses respecting the difference between acute methanol and ethanol intoxication in clinical manifestations, diagnosis, and treatment. Methods: A cross-sectional study was performed in 2020 on the emergency nurses from two educational hospitals. A total of 100 nurses participated in this study. The data collection tool was a researcher-made questionnaire, including demographic characteristics and questions concerning the identification and differentiation of acute methanol from ethanol intoxication. Moreover, the obtained data were analyzed using SPSS v. 20 at the significance level of P<0.05. Results: The present research results suggested that 21% of the examined nurses had a low level of awareness (<7) and 79% had a moderate level of awareness (8-13). The mean score of awareness was measured as 8.71 (range: 2-12). Nurses’ awareness was not related to age, gender, the duration of working experience, and educational level (P>0.05). Conclusion: The awareness of nurses regarding alcohol poisoning is moderate. Due to the importance of differentiating ethanol from methanol toxicity, considering the outcomes of the patients, nurses’ awareness should be increased.

Published: October 2021

Os pressupostos de sustentação teórica do Hapkido encontram-se intimamente ligados às influências dos povos orientais vizinhos, especialmente da Índia e da China. O objetivo geral deste artigo é apresentar um sucinto histórico desta arte marcial coreana e de seus fundadores. Já os objetivos específicos consistem em ressaltar a importância das técnicas marciais na contemporaneidade e a sua contribuição no desenvolvimento do potencial humano. A metodologia aplicada deu-se por meio de uma revisão sistemática de autores do tema no Brasil, na Coreia e nos Estados Unidos. Os resultados mostraram que as opressões que o povo coreano sofreu ao longo de sua história foram os principais motivos pelos quais esta arte marcial foi estruturada de forma bem-organizada e completa. O Hapkido provou a sua relevância no crescimento de grandes nações, na formação de treinadores e na preparação de lutadores e combatentes das Forças Armadas ao promover e desenvolver a disciplina, a ordem e a interação social. Conclui-se, portanto, que é preciso uma avaliação técnico-científica vinculando esta arte marcial diretamente à filosofia, psicologia, educação física e medicina do esporte, com aplicações práticas para a sociedade e para as comunidades especializadas em todo os continentes, principalmente aos profissionais de Educação Física que poderão valer-se deste conjunto de técnicas como modelo de treinamento para seus alunos.

Uma alimentação saudável, uma boa prática alimentar ou ainda, a ingestão de alimentos adequados em quantidade e qualidade suficientes para suprir as necessidades nutricionais, são essenciais para todos os cidadãos. O alimento deve permitir o crescimento e o desenvolvimento adequado do ser humano, sem exceder a capacidade funcional orgânica de seu sistema cardiovascular, digestório e renal. Tal prática possibilita a prevenção de várias doenças na infância e na vida adulta futura, entre as quais as deficiências nutricionais, as doenças crônicas, o sobrepeso e a obesidade. Diante desses fatores, em função das consequências do fechamento das escolas e encerramento de diversas ações solidárias governamentais provocadas pela pandemia da COVID-19, houve um aumento da fome e a desnutrição em inúmeros lares brasileiros. Sendo as comunidades localizadas nas periferias dos grandes centros as mais afetadas, tendo em vista, serem considerados os bairros/cidades dormitórios, onde habitam um alto percentual de trabalhadores que perderam seus empregos. Este trabalho objetivou relatar a ação realizada de agosto a dezembro de 2020 na comunidade de Guadalajara, Paudalho/PE, através do qual foi realizada distribuição de sopas em locais estratégicos. Após identificação e local para a realização do projeto, foi realizado um pré-cadastro, através do qual se identificava quantos membros da família habitavam na mesma residência, sendo esta informação crucial para que fosse definido o quantitativo de sopa a ser distribuída a cada semana. Ao longo do projeto foi possível atender, semanalmente, em média 100 beneficiados, majoritariamente mulheres, que se dirigiam ao local de distribuição para receber a refeição, O estudo revela a necessidade urgente de maior investimento em políticas públicas que possam reduzir a fome e a má nutrição no país, bem como minimizar a pobreza extrema.

Todas los días, el periodista debe enfrentarse con apariciones de la Virgen en el fondo de una taza de café, enormes anacondas que se tragan entero a un fornido tolimense de 22 años, una mujer de barrio miserable que leyó entre las escamas de un sábalo el número ganador de la lotería o con , cualquier otro hecho de una realidad inverosímil que, como dijo Gabriel García Márquez en su discurso de aceptación del Premio Nobel de Literatura, "vive con nosotros y determina cada instante de nuestras incontables muertes cotidianas".

Air merupakan komponen penting dalam kehidupan, namun masih banyak orang yang masih kurang peduli terhadap penggunaan air dalam keseharian.  Penggunaan air di dalam rumah tangga selama ini masih sangat sulit untuk dilakukan pengelolaan dalam penggunaan air secara efektif. Untuk menangani masalah tersebut, tentunya diperlukan sistem kendali yang dapat memantau dan mengendalikan keluaran debit air yang berlangsung secara real time dan terprogram demi meningkatkan efektifitas penggunaan air. Penelitian ini mengembangkan sistem Home Water Flow Monitoring (HEROIG) berbasis Internet of Things (IoT). Perangkat keras yang digunakan sebagai mikrokontroler dari sistem ini adalah  NodeMCU. Sensor water flow digunakan sebagai sensing hasil debit air dan motor servo sebagai kendali aktuator utama pada sistem ini. Sistem ini dirancang dengan menggunakan kontrol PID untuk menghasilkan keluaran debit air sesuai dengan keinginan pengguna. Pengujian sistem kontrol PID ini dilakukan dengan menggunakan beberapa percobaan masukan nilai parameter Kp, Ki dan Kd. Dari hasil percobaan yang menghasilkan nilai paling baik ketika Kp = 1, Ki = 1 dan Kd = 0,5.  Dari hasil perancangan yang diperoleh, dilakukan juga pengujian terhadap masing-masing nilai set point untuk menghasilkan keluaran debit air sesuai inputan pengguna. Hasil tersebut menunjukkan masih terdapat kondisi overshoot dan memiliki nilai eror <14%.

The Reflection of the Adoption of IFRS 17 “Insurance Contracts” on the Procedures for Auditing Insurance Contracts in the Iraqi Environment
Authors: Al-Mohammadi Mohammed Falah , Al-Mashhdani Bushra N. Abdullah
Published: October 2021

IFRS 17 aims to provide a unified basis for accounting for all types of insurance contracts, including reinsurance contracts, in a manner that benefits both investors and insurance companies and enhances the ability of the financial statements of insurance companies for comparison between companies listed in financial markets around the world. According to this standard, insurance contracts are accounted for on the basis of the Asset-Liability Approach and the use of fair values that the standard requires updating regularly in order to provide more useful information to the users of financial statements, as a result of the failure of reporting requirements for insurance contracts in the Iraqi environment to provide adequate and honestly representative information about the result of the activity and the financial position as a result of the failure of the requirements of the unified accounting system for banks and insurance companies with regard to providing appropriate bases for recognition, measurement, presentation and disclosure of insurance contracts compared to IFRS 17. Consequently, the insurance contracts audit program prepared by the Federal Board of supreme audit is insufficient and lacks the necessary procedures, also, this program includes audit procedures for insurance companies only and does not include companies that deal in contracts of an insurance nature, as well as the absence of an integrated program or guide approved by private auditing companies and offices in the Iraqi environment for the purpose of auditing these contracts, which requires a statement of the importance of adopting the International Financial Reporting Standard IFRS 17 and its reflection on the audit procedures that auditors must adopt when auditing insurance contracts. The two researchers relied on the opinions of a sample of academics and professionals specialized in this field by preparing a questionnaire that focused on the importance of adopting IFRS 17 and the reflection of adoption on the procedures for auditing these contracts in the Iraqi environment. The most prominent finding of the research is the need to adopt IFRS 17 because it provides clear and specific guidelines that help provide more useful information to users of financial statements in companies that deal in insurance contracts, as well as the impact of adopting this standard on the insurance contract audit procedures approved by the Federal Board of supreme audit and private auditing companies and offices in the Iraqi environment
