Published: September 2022

The task of language education involves the development of competent speakers who will apply the acquired theoretical knowledge in language and communication activities. The practical implementation of oral and written speech of learners includes the study of syntactic units, their construction and functioning. The article clarifies different approaches to the study of syntax, among which three most important ones are identified, which predominate in characterizing the features and properties of the system of syntactic units (formal-syntactic, semantic-syntactic, or semantic and communicative, or functional). A number of modern ones (computer, cognitive) have been singled out, which contribute to the analysis of other natural possibilities of syntactic phenomena and their functioning. The emphasis is placed on the unity of communicative organization of syntactic constructions with structural and semantic features. The linguists’ views on the combination of aspects through the establishment of interconnection and interaction (logical-grammatical, structural-semantic, functional-pragmatic) are demonstrated. In addition to a number of principal approaches to the study of the syntactic structure of a language, the main ones are specified and substantiated, aimed at improving the level of learners’ knowledge. Gaining practical experience by the learners provides pragmatic, which contributes to the formation of skills to convincingly express their position. It is emphasized that logical, communicative and cognitive approaches are integral to studying syntax, as they are able to enhance the development of competent speakers who are able to communicate in different life situations.

The current state of development of labour potential of Ukraine requires the formation of new innovative approaches to vocational training retraining and advanced training of adults the features of which are to ensure compliance between the demand of ship-owners for employment of seafarers and their skills to work in the maritime labour market based on the use of information and communication technologies (ICT) on board modern ships. In connection with this approach, we note that the content of the system of vocational training retraining and advanced training of adults of maritime profile involves creating conditions for theoretical and practical mastery of didactic features of the educational process by those involved in it, namely teaching and instructional composition of the educational institution. The authors of the article reveal the essence of the concept of adult student of the maritime educational institution which means a person who has some education in maritime professions, practical experience and experience on board ships of the sea and river fleet, learns to solve their life and social problems and achieving specific career growth, expects to master professional competencies during training, seeks to be competitive in the maritime labour market. This category of future command staff is most in demand in the maritime labour market because it has undergone initial practical training on seagoing vessels in the ranks of privates and has gained experience in the ship's crew. The educational process with this category of students requires the teaching staff to improve the quality of education taking into account the professional experience and demand of students, equipping the material and technical base with modern training equipment in combination with ICT, providing methodological support of the educational process using innovative learning technologies. Vocational education of adults in higher education institutions should be considered as a specific pedagogical system the functioning of which is determined by the creation of its pedagogical environment.

Authors:   National Akademy of Pedagogical Sciences of Ukraine, Zhurian Viktoriia
Published: September 2022

The proposed article notes that the situation of the global environmental crisis requires understanding of the latest approaches to the analysis of the interaction between nature and society on the basis of the formation of a certain environmental competence. The study also reveals the basic concepts of environmental education, such as environmental literacy, environmental awareness, environmental thinking, environmental competence and culture. The relationship between the environmental competence and culture is revealed. It is determined that the main goal of environmental education is the development of the ecological culture of an individual, which, in accordance with the competence-based approach, is based, firstly, on the improvement of the relevant competencies of future specialists. At the same time, in a narrower, practice-oriented connotation, environmental competence is understood as a set of personal qualities that determine the ability of maritime industry specialists to make adequate decisions in a specific environmental situation. In a broader sense, ecological competence is considered as a component of the ecological culture of the individual, reflecting the relationship of a person with the surrounding socio-natural environment. In the proposed study, the features of the components of the environmental competence of shipmasters are analyzed, the specifics associated with the peculiarities of professional activities, international conventions, etc. are highlighted. Based on the theory of the competency-based approach, features of professional activities, specific properties of environmental competence, the study proposes a structure of the environmental competence of future shipmasters, which includes 5 components: axiological (value-motivational); cognitive (possession of environmental knowledge, environmental thinking, etc.); activity-behavioral (practical-technological); emotional-volitional (introspection of personality traits, emotional reactions); regulatory (ownership of the regulatory framework). Prospects for further research lie within the scope of the formation of the environmental competence in future shipmasters based on the psychological and pedagogical conditions of training

Technologies for the implementation of the model for the formation of intercultural competence of medical students in foreign language classes
Authors:   Petro Mohyla Black Sea National University, Strelchuk Yana
Published: September 2022

One of the most important tasks of a higher medical school at the moment is the preparation of a highly qualified specialist who meets all the requirements of the labor market, that is, demonstrates not only high professional skills, but also a readiness for productive activity in an intercultural environment. The study of the work of Ukrainian universities and the analysis of pedagogical literature show the inadequacy of methodological support for the process of forming intercultural competence of students of a medical university. There is a contradiction between the growing volume of information and the crisis of didactic methods of training specialists, which requires a shift in emphasis to modern technologies of vocational training. The need to change the priorities of professional training of specialists towards the development of creative thinking and mastering by students the tools for managing their own educational activities becomes obvious. In this article the author presents a system of effective teaching technologies for the successful implementation of a model for the formation of intercultural competence of medical students in foreign language classes. The system includes the following: discussion technologies (development of students' critical thinking, the formation of their culture of communication in various situations of professional and everyday communication in an intercultural environment); game technologies (simulation model of real professional activity, aimed at the formation and consolidation of professional skills and abilities); problem technologies (modeling a problem situation without risk for participants, searching for a systematic approach to solving the problem); design technologies (independent creative work, development of presentation skills and protection of products of their own activities).
Information and intellectual systems in modern management
Authors:   “Odessa Maritime Academy”, Zhytomyrska Tetiana
Published: September 2022

The evolution of information technologies andsystems is increasingly determined by their intellectualization. Intelligent information technologies are one of the most promising and rapidly developing scientific and applied areas of informatics. The goals of intelligent information technologies are to expand the range of tasks solved with the help of computers, especially in poorly structured subject areas, and to increase the level of intellectual information support of a modern specialist, in particular, a specialist in the field of management. The proposed study deals with the use of modern intelligent information technologies in management. Namely, the use of intelligent information systems. The functions of artificial intelligence that can be used in the development of an intelligent system are disclosed. The main essence of this concept is analyzed. The role of intelligent systems in many areas is shown. The main tasks of these systems are determined. The questions of the development and the effect of the application of intelligent information technologies in solving management problems in the conditions of uncertainty and dynamism of the environment for the functioning of organizations are revealed. It is noted that in management, data analysis includes procedures for describing, diagnosing, forecasting, decision-making and control. The paper notes that, despite significant advances in the field of artificial intelligence, there is still a certain gap between technical developments, artificial intelligence software and the possibilities of their wider practical application, in particular in management. On the example of organization management, the advantages of using artificial intelligence systems for solving both various subject tasks and managing an integrated system of an organization as a whole are especially clearly visible. Thus, the intelligent system can constructively perform decision support functions at more constructive levels. The main difference between intelligent decision support systems and information and reference systems is that a mandatory element of functioning is the formation of recommendations or draft decisions.

Published: September 2022

The article focuses on the importance and relevance of actualizing the problem of improving the professional culture of research and teaching staff in the contemporary context. It is emphasized that the profession provides a certain set of necessary personal qualities, which being integrated into the structure of an individual, create a certain level of the professional culture. The specificity of the professional culture is determined mainly by the uniqueness of the activity, a wide range of functions, competencies entrusted to the specialist. In a broad sense, the culture of professional activities is defined as a certain level of performance of one's duties. The emphasis is laid on socially significant motives (needs, interests, values, views); compliance of psychophysical personality traits with the requirements of professional activities; the degree of development of mental processes of a personality (thinking, memory, emotions, feelings, will); completeness and depth of acquired psychological and pedagogical and special knowledge, skills, abilities, i.e. acquired experience; social activities. The importance of pedagogical values is highlighted: values – goals and values - motives; values – knowledge; technological values; values – properties; values – relationships. The functions of the pedagogical culture are emphasized: the function of transmitting the social experience; regulatory, which adjusts the behavior of a teacher, as well as the quality indicators of a teacher in the process of transmitting the social experience; symbolic; axiological; creative features. Three groups of contradictions of the formation and development of professional and pedagogical culture of a teacher are considered: sociocultural, general pedagogical and individual creative. Socio-cultural contradictions are resolved through the search for the ways to overcome the crisis of pedagogical culture. General pedagogical contradictions reflect the peculiarities of the educational process in higher education, the nature of pedagogical interaction between teachers and students. Teachers associate the identification and elimination of individual and creative contradictions with the creative self-actualization of the teacher's personality in the process of pedagogical activities.

The article presents a method to determine an amount of alunite in alunite ore and technological samples by alternative method. The essence of the method is that the alunite mineral in the ore is heated to the temperature of complete decomposition (800-8500C) and the degree of alunitation of the ore for the total mass loss, based on the amount of aluminum oxide and sulfur trioxide. The method was compared with other available methods (thermal, chemical, X-ray phase). The advantage of the method is that more than one sample is analyzed at a time, the analysis is completed in a short time, no preliminary preparations are made, nor chemical reagents are used. Alunite ore consists of alunite and non-alunite (kaolinite, hematite, quartz). Since the mass loss during the heating of the ore is mainly caused by the decomposition of alunite, a mathematical relationship of a%=2.34ωloss was found between the loss and the degree of alunitation. According to the degree of alunitation, for the aluminum oxide and sulfur trioxide in the ore, the expressions ω(Al2O3)=0.8775⋅ωloss, ω(SO3)=0.6888∙ωloss were obtained. Chemical, derivotographic methods of analysis experimentally confirmed the adequacy of these equations. It was established that in order to completely decompose the ore, it is necessary to heat it at 8500C for half an hour and at 8000C for an hour

This paper presents the results of studies of the anti-seize properties of (2,2-dimethyl-4-methylene1,3-dioxolane-allyl and benzyl)disulfides synthesized on the basis of 2,2-dimethyl-4-chloromethyl-1,3- dioxolane, sodium disulfide and allyl and benzyl chlorides, respectively, in the composition of transmission oils. The synthesized compounds are new compounds not previously described in the literature, the structure of which has been proven by studying their physicochemical properties, elemental composition, and IR spectroscopy. It revealed that the synthesized compounds in terms of extreme pressure efficiency are significantly superior to transmission oil MS-20, as well as bis(2,2-dimethyl-4-methyl-1,3- dioxolane)disulfide, previously synthesized by the authors of this article and a typical extreme pressure additive ethylene-bis-isopropylxanthate (LZ-23k). It found that the replacement of one of the 1,3-diocosolane fragment in bis(2,2-dimethyl-4-methylene-1,3-dioxolane) disulfide with allyl or benzyl radicals leads to an improvement in anti-seize properties due to their better adsorption on metal surfaces of rubbing parts.

Authors:   El Colegio de la Frontera Norte, Toudert Djamel
Published: September 2022

The availability of Internet at home is one of the most important steps to enjoy the benefits that come from its use. In this sense, knowing the weight implied by the availability or lack of the network becomes strategic in the design of policies and actions to intensify the socio-territorial penetration of the Internet and the empowerment of its users. The aim of this research was to develop a function for predicting Internet availability in households, based on microdata from the 2020 population and housing census conducted by the National Institute of Statistics and Geography (INEGI). This type of prediction, in addition to clarifying the socio-territorial conditions involved in the physical availability of the Internet in homes contribute to the structuring of an intervention context for the public and private factors of digital disengagement. In methodological terms, the prediction function is based on a random sample of 11 000 census interviewees, divided into two groups of equal consistency: the first has Internet at home and the does not. To generate the prediction, a linear discriminant function was used and valued by a score function. The quality of the prediction was estimated through an internal evaluation with Bootsrap (75% of the sample) and an external one (25% of the sample), both of which were complemented with an analysis of the ROC curve and LIFT graph. The resulting function exhibits a sensitivity of 76.9%, a specificity of 20.5% and a discriminant capacity of 86.7% in a 95% confidence interval. With these efficiency parameters, the found function becomes a possible effective prediction tool for both reflection and action against the digital divide in its initial stage.

This study aims to evaluate associations between the immunochromatographic rapid test technique and Trichomonas vaginalis (TV) infection in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in Taiwan. All patients received post-prostate massage urine (VB3) Trichomonas rapid tests. The demographic characteristics and urogenital symptoms of CP/CPPS were recorded. Routine urinalysis of VB3 was also performed, and laboratory examination results of semen were recorded if available. A total of 29 patients with TV infection and 109 without TV infection were enrolled, which reflected that the prevalence in patients with TV infection was approximately 21%. Patients with TV infection displayed a significantly higher frequency of suprapubic/lower abdominal pain (p = 0.034), semen leukocyte > 5/high-power field (HPF) (p = 0.020), and an inflammatory type (category IIIA) (p = 0.005) than patients without TV infection. A higher prevalence of TV infection was found in patients with category IIIA (47.37%). No significant difference was found in the symptom duration and other clinical symptoms. In conclusion, the high prevalence of TV infection was revealed in CP/CPPS patients using the VB3 rapid Trichomonas test, especially in CP/CPPS patients with category IIIA. Thus, rapid TV testing might be vital for CP/CPPS patients in the hospital.

Lack of understanding regarding halal label certification in a start-up business within the Nahdlatul Ulama University Surabaya is an obstacle in implementing halal product guarantees for a product or service. If further researched, halal certification on a product, especially in a start-up, will affect customer satisfaction and increase the profits of a business. Therefore, this community service activity aims to provide literacy and training about a halal certification to increase customer satisfaction in the Unusa Student Start-Up business. This community service activity targets 26 students of Nahdlatul Ulama University Surabaya who have a start-up business. The method used is lecture and question and answer. Meanwhile, the evaluation of activities is carried out by distributing questionnaires regarding knowledge related to halal certification and customer satisfaction, which is then analyzed using Paired Sample Test. The results obtained are a significant increase in knowledge (p-value 0.000). This is evidenced by the average knowledge score before training of 3.83 to 5.42 after training. After this training, students hope to get further assistance related to halal certification in start-up businesses
GLOBALIZATION AND PROBLEMS OF LINGUISTIC DIVERSITY

Globalization modernizes developed national languages, but accelerates the decline of «small» languages. The number of the latter is decreasing dangerously, and at an increasingly rapid pace. Оf the current 7,000 languages, the vast majority will not survive to the end of the 21st century. 150–200 languages (2–3% of the total) have a secure future. Among other things, languages fall into decay because they do not fulfil all the functions a standard language should fulfil. They are displaced from significant spheres of communication by more powerful languages. The less a language serves the socially significant spheres, the less often it is used, the faster it depreciates and decays. The traditional parameters of language vitality (number of speakers, the presence of writing and state status, standardization, areas of use, economic power) are now joined by another one — the presence of the language in the computer environment, its digital equipment. According to this criterion, languages are divided into three groups: 1) languages that have made the digital leap; 2) languages that have shown digital potential; 3) languages that have not overcome the digital threshold. Hence, their prospects in the 21st are evident. The greatest hopes for the preservation of the linguistic diversity are associated with the progress of machine translation technology. In the future, it will assume the function of an international language: enabling written and oral interaction of everyone with everyone without the need to know each other’s language. Improved machine translation is not only a convenience for speakers, but also a way to support multilingualism, a chance to preserve the numerous national languages. It can be expected that thanks to machine translation, the competition of languages for spheres of use will sharply weaken, instead their co-evolution will begin, that is, parallel, conflict-free development.
