PRIMARY SCHOOL TEACHER IN MODERN WORLD
Authors:   Volodymyr Vynnychenko Central Ukrainian State Pedagogical University, Radul Olha
Published: October 2022

Primary school is the oldest unit in the system of education. In modern world it is the primary school teachers that make up the biggest part of the total number of teachers since the world is developing unevenly and in many developing countries only elementary stage of education is widely accessible. Due to the mass character of the primary school teacher profession the study of the position of the teacher in different countries remains a topical direction in comparative pedagogical researches. The article presents the analysis of the most widely spread parameters and characteristics of the primary school teacher in modern world, their work, peculiarities of training and further professional development. The statistics show the uneven increase of the number of primary school teachers: the biggest rise takes place in the developing countries as the result of the mass character of elementary education there. The number of teachers in the developing countries increases following the decrease of class size and the introduction of new teacher categories. A firm indicator of the primary school teacher is feminization. There are different approaches to the assessment of the teachers’ work. Working conditions differ as well, which manifests itself in the “teacher–students” coefficient ratio and the teaching workload. All this predetermines the high importance of the problem of professional training of teachers. According to the implemented reforms higher pedagogical education is generally recognized for professional development of a teacher. It is represented by different types of educational establishments. Primary education will continue to be the most massive part of the educational systems of all countries of the world - developed and developing - and therefore, among all the world's teachers, there will be the largest number of primary school teachers. Every country will always need the most primary school teachers. Accordingly, the study of the qualitative and quantitative characteristics of the primary school teacher's profession, as well as his training and professional development in different countries, will always be a relevant topic of comparative research.

The article is devoted to the problem of preparing future specialists of the State Emergency Service of Ecology for professional activity by means of information and communication technologies. The concept of "ecological culture", which is considered as a basic element of the system of environmental education, equips a person with the necessary knowledge about the peculiarities of the interaction of society and nature, the course of natural processes, the influence of anthropogenic loads on them and the adverse consequences of such influence, is considered in detail. This especially applies to civil defense specialists who, by virtue of their professional duties, must possess not only specialized knowledge and skills, but also a developed environmental culture. Ecological culture contributes to the development of an ecologically oriented strategy of life and regulates the attitude to the natural environment by moral and scientific means. The basis of the formation of ecological culture is ecological education and upbringing, therefore, precisely in the process of professional training, it is most appropriate to instill ecological culture. The formation of ecological culture should take place by involving specialists in active, creative activities. Such education should be carried out in an active form, using "direct contact" with the natural environment. Specialists should qualitatively build the educational process, select such material that will be understood by the audience and reinterpreted in a valuable way by it, which will contribute to the formation of socially valuable motives in the attitude to nature, instilling the necessary abilities and skills of interaction with the natural environment, raising the level of environmental culture in general. Summarizing what has been said, it should be said that the level of environmental culture of specialists remains low and society needs to intensify the process of forming an ecological culture by means of formal and informal environmental education and training. Environmental education is represented by a system of knowledge aimed at mastering the theory and practice of general ecology, and includes elements of geographical, socio-economic, technical and legal fields of knowledge. Environmental culture of a person is a complex psychological formation, which consists of a system of knowledge, practical abilities and skills, beliefs and learned norms of interaction with the environment. Ecological culture as a basic element of the system of environmental education equips a person with the necessary knowledge about the peculiarities of the interaction of society and nature, the course of natural processes, the influence of anthropogenic loads on them and the adverse consequences of such influence.

PROFESSIONAL PERSONALITY DEVELOPMENT AS A COMPONENT OF THE PROFESSIONAL CULTURE OF THE FUTURE TEACHER
Authors:   Volodymyr Vynnychenko Central Ukrainian State Pedagogical University, Honcharenko Ivan
Published: October 2022

The article examines the peculiarities and importance of professional self-development as a component of the professional culture of the future teacher. The professional and personal development of an individual as a specialist in his field is possible only if a person has a certain value-motivational attitude towards his professional and personal future, which ultimately translates into self-development and self-improvement. Professional and personal self-development cannot be considered without a relationship, since professional self-development is a continuation of personal development. Special attention was paid to the fact that the professional self-development of future teachers is a purposeful, self-discovery and self-projecting type of activity of a person who wants to realize himself as a professional in a certain field of employment. The basic definitions of the concepts of "development" and "self-development" are explained. The main conditions for the professional self-development of students who plan to be teachers in the future are defined and characterized, namely: a positive attitude towards the profession of a teacher and the implementation of pedagogical activities; professionally important qualities and motives of professional activity, as well as the student's internal desire for professional self-development; knowledge, skills, skills of professional self-development, which act as means of self-development. An important factor in the professional self-development of a future teacher is the educational environment. Because this environment is a flexible, open, sometimes conflicting and critical structure that "lives" in constant dynamics, which as a result provokes and stimulates a person to professional self-development. It is stated that professional self-development of future pedagogues and teachers is a purposeful activity of the individual, which includes aspects of self-knowledge and self-projection to improve one's activity and profession in the educational institution and realize oneself as a professional and specialist.
Emergent online discourses and the (re)framing of women’s identity
Authors: Mpofu Sibongile
Published: October 2022

The advent of social media communication platforms, specifically blogs as sites of politicalengagement, means that they now constitute the key carriers of democratic public discourse.Previously marginalised groups such as women can now deliberate, interpret and re-frame theirown narratives and identities. This article examines how Zimbabwean women are using blogsto resist and subvert women’s ascribed identities, improve the political, economic and culturalrepresentations of women, and enhance women’s participation in politics. Using feminist criticaltheory, the article describes how women-owned content from selected Zimbabwean blogsframes women’s political, economic and cultural identities, and how women producing their ownmessages are improving women’s representation in society. Data obtained through qualitativecontent analysis of blog posts reveal that, as sites of agency, blogs offer possibilities for reframingand re-presenting women’s political and cultural identities. Blogs act as sites for thesubversion of ascribed identities that continue to position women as second-class citizens. Thearticle concludes that digital media, particularly blogs, can be used as sites of resistance to powerby bringing to the fore counter narratives that have been obscured from mainstream discourse,and at the same time affording women direct influence over their public image.

Published: October 2022

Nigerian women face patriarchal subjugation and intimidation both politically, economically andsocially, just like most women in all parts of Africa. But this scenario seems to be different in thesocial media landscape, where young Nigerian women are not only making waves but are callingthe shots as well. This study is aimed at critically assessing the Nigerian blogosphere in order toascertain how five female bloggers, namely Linda Ikeji, Uche Pedro, Stella Dimoko Korkus, TosinAjibade and Judith Emike Audu-Foght, have impacted positively on the lives of women. The studyreviewed relevant literature and also analysed what women-related contents each of the fivebloggers post in their various blogs. Apart from the study of the contents of the blogs, interviewswere employed in collecting relevant data from the bloggers. These two approaches helped inanswering the research questions which guided the study. The paper concludes that throughblogging, the identities of Nigerian women have been positively impacted on in various ways likein the building of portfolios, sharing of knowledge, self-expression and building of professionalnetworks. The study recommends that since the mainstream media have failed to give voices toAfrican women, it is high time women take it upon themselves and better their identities throughthe opportunities offered by the internet.

Authors: Hadzik Robert , Pietrzak Marta , Kosson Dariusz
Published: October 2022

Aim: The present paper attempts to find the risk factors for hypotension suffered by patients in the postoperative period taking into account the following aspects: gender, type of anaesthesia, ASA score, type of surgery, and time after surgery when it is likely to be at its lowest.
Material and methods: The main method used in the study was to analyze the medical records regarding patient data in the perioperative period. Patients had their mean arterial pressure (MAP) measured and documented in the Intensive Care Chart. Information on the type of surgery and choice of anesthesia was obtained from the Anaesthesia Records. Eighty patients participated in the study.
Results: There was no clear correlation between the gender of the patients and the decrease in blood pressure. Hypotonia occurred in the 8th hour after surgery in both men and women in the study group. It was observed that in subjects under 80 years of age, hypotonia occurs mainly in the 8th hour after the procedure, while in older subjects – after 12 hours following surgery. The type of procedure affects the occurrence of hypotonia. In patients undergoing general and epidural anaesthesia, the highest decreases in mean arterial pressure values were observed 8 hours after surgery compared to other methods of anaesthesia. The ASA classification proved useful in predicting the incidence of hypotonia; in Class 4 patients, it was pronounced and persisted for 12 hours after surgery.
Conclusions: It cannot be conclusively stated which factors most influence the occurrence of hypotension in patients after surgery.

Anaerobic bacterial infections are a broad group of conditions ranging from superficial skin infections to deeply embedded necrotic soft tissue infection. It has been observed that amongst all the microorganisms causing soft tissue infection, as many as 70% of anaerobic bacteria are unquestionably related to mortality in fulminant infections. Such infections are most commonly caused by an open wound that is insufficiently disinfected, or through the wound coming into contact with soil or human or animal faeces. This is particularly the case for wounds resulting from traffic accidents and injuries sustained in agriculture. In 80-95% of cases, the bacteria Clostridium perfringens is responsible for the appearance of gas gangrene manifested by sharp pain and crepitus in the wound area, as well as disseminated intravascular coagulation and septic shock. Due to time-consuming diagnosis and delays in obtaining the results of bacteriological tests, identifying the condition and commencing treatment relies mainly on a paramedic’s knowledge and experience. Improving the body of knowledge on soft tissue infection and awareness of the potential risks can affect the patient’s prognosis.

Novel Algorithm for Nonlinear Distortion Reduction Based on Clipping and Compressive Sensing in OFDM/OQAM System
Authors: Vaigandla Karthik Kumar , .Benita J
Published: October 2022

Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) signal has high peak-to-average power ratio (PAPR) problem. It not only affects the distortion in High Power Amplifier (HPA) but also results in bit error ratio (BER) degradation. In this paper an improved algorithm based on Clipping and Compressed Sensing (CS) is proposed. The transmitter uses clipping to reduce the PAPR and, the receiver uses an improved inverse model, to reduce the nonlinear distortion introduced by HPA and CS cancels the signal distortion introduced by clipping. Simulation results show that the proposed method not only significantly reduces the PAPR of OFDM/OQAM signals, but also effectively improves the BER performance of the system.

Authors: Rao S. Srinivasa , Reddy K. Chenna Keshava , Chand S. Ravi
Published: October 2022

Ensuring the reliable and energy efficient data routing in Wireless Sensor Networks (WSNs) is still remains one of the challenging and demanding tasks due to its dynamic architecture. For this purpose, the different types of routing methodologies and security schemes have been developed in the conventional works. However, it faced the problems related to increased network overhead, high cost consumption, reduced Quality of Service (QoS), and inefficient bandwidth utilization. The main contribution of this work is to implement an optimization based secured routing methodology for establishing an energy efficient data communication in WSNs. For clustering the nodes, the parameters such as residual energy, trust score, and mobility have been considered, which also helps to simplify the networking operations. Moreover, the outliers in the network are detected with the help of Spatial Temporal Fuzzy Inference System technique, which generates the set of inference rules based on the distance, energy, and mobility measures. Also, the Crow-Whale Optimized Secured Robin Routing (CWOSRR) is used to enable the data transmission in the network through the optimized path, which avoids the loss of information. During the simulation analysis, the results of the proposed technique is validated and compared by using various performance measures.

Published: October 2022

Temperature and charging time are critical parameters during charging period of a battery as temperature rise affects battery life. In a particular charging method, setting high current minimizes charging time but raises temperature. In this study attention is given to multistage constant current charging approach to shorten charging time while maintaining battery temperature below preset range. Battery charging characteristics of various methods are studied, and their performance is compared. The proposed multistage charging method is compared with constant current constant voltage and traditional multistage charging method. The experimental results obtained show that, the proposed method reduces the charging time by 42.22 % and 9.3 % as compared to the constant current constant voltage and conventional multistage charging method respectively, while limiting the rise in battery's temperature to 5°C above room temperature. Further in the proposed method, battery temperature is reduced by 20% as compared to the conventional multistage method.

Published: October 2022

High-quality electrical energy is the most needed thing for standard living. We use power electronics converters for the conversion of different forms of electrical energy and we use them for producing quality power output. We use semiconductor devices as switches in the process of conversion of DC-DC, AC-DC, AC-AC, and DC-AC according to the requirement of the system. In this paper, an attempt is made to analyze the quality of output power from a multilevel inverter which is used in the conversion of DC supply to AC output voltage. Production of quality power by optimizing the multilevel inverter switching using Whale Optimization Algorithm helps the proposed inverter topology to perform well. The suggested topology and the optimization technique will help in harvesting multiple renewable energy sources with improved quality of power. Different DC sources of different voltage levels could be connected in input and the resultant AC output has less ripple content as per the IEEE standard. A detailed comparison has been made to show the superiority of the proposed algorithm.
