Refractive and Binocular Vision Status and Associated Asthenopia among Clinical Microscopists
Authors: Kaiti R. , Shrestha J. B. , Dev M. K. , Pradhan A. 
Published: April 2023

Background Clinical microscopists are at a greater risk of developing binocular vision anomalies and asthenopia.
Objective To assess the refractive and binocular vision status and to explore the association between the presence of asthenopic symptoms and microscopy work among clinical microscopists working at medical laboratory department.
Method This cross-sectional study involved 37 clinical microscopists working at medical laboratory department of Dhulikhel Hospital, Nepal. The study was conducted from January to December 2013. Only those participants who had been using microscope for at least a year were enrolled in this study. Each participant underwent distance visual acuity (VA) assessment, refractions, and orthoptic evaluation, including measurement of distance and near phoria, near point of convergence (NPC), near point of accommodation (NPA), positive fusional vergence (PFV), adduction, and calculation of accommodation convergence/accommodation (AC/A) ratio. The tear test was also carried out in each subject. Information about use of glasses, microscopy work (duration, and time spent per day in microscope), and visual symptoms associated with the use of microscope such as eye strain, headache, double vision, and near vision were collected.
Result The mean age of the clinical microscopists was 29 ± 5.7 years. The prevalence of refractive error was 56.76% and the mean spherical equivalent (SE) refractive error was -0.77 ± 0.86 D. Refractive error had neither correlation with microscopy work and asthenopic symptoms associated with it, and nor with binocular vision parameters- NPC, AA and AC/A ratio. However, there was a positive association between asthenopic symptoms and microscopy work. There was statistically significant difference between symptomatic and asymptomatic subjects for binocular vision parameters, including NPC, AA and positive fusional vergence (PFV) for near.
Conclusion Microscopy work has an impact on near binocular vision. Asthenopic symptoms bear a positive association with microscopy work. Refractive error has no significant correlation with either microscopy works or associated asthenopic symptoms.

PREPARATION OF FUTURE CHEMISTRY TEACHERS FOR THE USE OF WEB TECHNOLOGIES FOR VISUAL MODEL TEACHING OF STUDENTS
Authors: Kochubei Elena 
Published: April 2023

The article examines approaches to training future chemistry teachers to use web technologies for visual modeling of students, which are proposed to be used in the methodology of teaching chemistry to students to explain physico-chemical phenomena that are quite difficult to understand, in which verbal description becomes ineffective. The tasks that orient the consideration of visualization in the process of teaching chemistry in connection with the web-technology of learning in the direction of optimal consideration of psychological and neurophysiological regularities of perception, thinking and memory are revealed. The specifics and main content components of visual-model teaching of chemistry as a factor of the integral pedagogical process of the professional training of the future teacher are determined. It is proposed for the future chemistry teacher to form such a competence as a mutual transition from a non-verbal sign-symbolic record of a chemical object (concepts, formulas, laws, etc.) to a verbal (adequate) description.The specifics of the educational activity for the development of chemical knowledge and the specifics of the process of receiving information and its development by students are revealed. The need to optimize the volume of perception and information flow, the significance of the content of information through a certain sign system, and the use of its coding means has been established. The conditions for the optimal transmission of educational information, the importance of web-technologies of learning are revealed: a clear statement of the purpose of communicating new material; justification of the form and means of its communication; assessment of the ability to perceive information regarding its volume, content accessibility; didactic and psychological preparation of students to perceive information in order to transform it into knowledge.

FEATURES OF THE DEVELOPMENT OF MUSICAL HEARING IN THE ORCHESTRA TRAINING OF A PLAYER OF WIND INSTRUMENTS
Authors: Palazhenko Oleg , Vytkalov Serhii , Tsyulyupa Stepan 
Published: April 2023

The article presents and characterizes the most important approaches to the development of the musical ear of brass musicians in the process of their orchestral training. Professional training for the development of musical hearing among brass performers in institutions of higher education of the artistic direction will be effective and purposeful, provided that the musician observes continuous and thorough auditory self-control, which will ultimately help the performer to coordinate and direct the work of the entire performing apparatus as a whole. Professional mastery of musical ear is a key element of musical perception by a brass musician, figurative and emotional thinking that is synthesized on the basis of the perception of musical language, and therefore becomes the main basis for revealing the composerʼs idea by the performer and the embodiment and transmission of a musical image filled with a wide variety of artistic content. Possession of absolute hearing gives the musician-performer certain advantages, because he can accurately imagine the pitch of each sound before its real sound begins. Practice shows that it is quite possible to fully master the art of playing an instrument if you have good relative hearing. It is only necessary that the musical ear of the performer is sufficiently subtle and flexible, capable of constant development and improvement in the process of communication with the instrument and music. In the process of purposeful development of auditory abilities, the performer must quickly master the ability to perceive music in a complex way ‒ to simultaneously listen to the pitch of the melodic line, its intonation development, timbre coloring, rhythm, harmony, character of presentation. Without this skill, the performer will not be able to fulfill his main task ‒ to understand and reveal the artistic content of the music being performed.

THE MODEL OF FOREIGN LANGUAGE COMPETENCE FORMATION OF FUTURE ENERGY ENGINEERS
Authors: Horbatiuk Roman , Bilan Nataliia 
Published: April 2023

The paper presents the model of the formation of future energy engineers’ foreign language competence, which conditionally reproduces the process of step-by-step learning of a foreign language for professional purposes and the development of practical knowledge and skills of receptive and productive types of linguistic activity under specifically created conditions due to the use of a range of specially selected didactic and methodological toolkit of informational, audiovisual and visual type focusing on project learning technologies. Based on the results of the research, its main components were determined and analyzed, and their inverse relationship and interaction were substantiated too. It was established that the developed model belongs to the structural and functional group. It was found that the structure of the model is determined by a complex of interconnected and complementary elements, which are combined into four blocks: motivational-target (goal, task, social order), didactic-methodological (approaches and principles of learning), content-processual (stages of foreign language training, pedagogical conditions, methods, technologies, forms, means of education), evaluation-resultative (components, levels), formation of foreign language competence, result). The functionality of the model is characterized by a set of properties that reveal its ability to perform a number of functions, in particular: educational, organizational, technological, managerial, cognitive, developmental, communicative, competent, controlling. The model design of foreign language competence formation for the future energy engineers was carried out taking into account the specifics of the professional training of higher education graduates specializing in the field of knowledge 14 Electrical engineering and the specifics of their future professional activities. It has been determined that the implementation of the suggested structural and functional model into the educational process of students’ foreign language learning results in the formation of a foreign language competence of would-be specialists in the field of power engineering, who are able to perform all the types of engineering activity using the relevant metalanguage in their professional environment.
Keywords: model, structural and functional model, formation, foreign language training, foreign language, foreign language competence, future energy engineers, higher education applicants, education environment, knowledge.

Gendered Power Struggles beyond the Male-Female Dichotomy
Authors: Lokot Michelle 
Published: April 2023

Abstract
Analysis of gendered power struggles often describes men's use of power over women. In some academic research, as well as analysis by development and humanitarian agencies who seek to promote gender equality, power may be framed narrowly. Such analysis may neglect how family relationships are shaped not only by gender but also by intersections between gender and age. This article is based on feminist ethnographic research among Syrian refugees in Jordan as well as interviews with humanitarian workers. It uses accounts of power struggles between Syrian mothers-in-law and daughters-in-law to illustrate how family dynamics shift as women advance in age. The paper complicates assumptions about men's power, arguing that policy-makers and gender practitioners should also consider how older women use power.

Transport protocols in IEEE 802.11 multihop wireless networks (MHWN) face performance degradation problem due to wireless medium characteristics and multihop nature which induce several types of packet loss including collision, random channel errors and route failures. The common approach to address this problem is that thetransport protocol should exploit the MAC information in order to regulate efficiently the source rate in MHWNs. In this paper, we propose to use twoMAC metrics: the Medium Access Delay used to detectthe network contention level, and the Average Transmission Time used to estimate the effective packet sending rate by which the network will not be overloaded. The novel rate control mechanism based on these two metrics is called MAC Metric based Rate Control (MMRC) and is expected to provide better performance than similar rate control mechanisms interms of fairness, packet loss rate and delay in MHWNs

This paper proposes a new watermarking algorithm that is an improvement of the public key robust watermarking algorithm for color images of R.Munir. In this new algorithm, the public key is areal sequence chosen according to a normal distribution with mean = 0 and variance = 1, and the secret key is a random permutation in subsets of the public key. The theoretical analysis and experimental results show that the proposed algorithm is more robust than R.Munir algorithm while quality of watermarked images is the same.

The crime fiction genre is one of many clichés, including isolated locations, technology struggles, law enforcement errors, red herrings, and more. These clichés interact with various class, gender, language, and religious identities that influence how investigations evolve and how the genre is received by its audience. Tana French’s The Secret Place (2014) and Oyinkan Braithwaite’s My Sister, the Serial Killer (2018) all interact with these genre conventions through isolated boarding schools and mansions on hilltops, law enforcement errors, investigative dynamic duos, and more, but the most significant of genre conventions is their consideration of the scapegoat and its functionality. In this essay, a scapegoat is a character knowingly forced to endure the blame and punishment for another’s actions. While these pieces follow genre conventions in the presence of a scapegoat, each piece of literature juggles red herrings and the class-based scapegoats in new lights. These pieces transcend the genre by forcefully calling out the class-based scapegoat, considering the perspective of the scapegoat, and vindicating the scapegoat. This essay will investigate the role of the scapegoat within The Secret Place and My Sister, the Serial Killer within the context of literary crime fiction genre conventions with Frantz Fanon’s Wretched of the Earth (1961) as a framework to examine the significance of class, race, and violence in the decolonization of literary crime fiction. Tana French and Oyinkan Braithwaite transcend genre conventions established by wealthy, white English authors such as Agatha Christie by confronting contemporary issues through their consideration of the class-based scapegoat. This confrontational transcendence utilizes scapegoats to call out the marginalization and oppression of diverse populations by privileged individuals and subsequently replace the traditionally privileged individuals with the previously marginalized people.

Authors: Calle Marcelo , López Valeria , Rivera María 
Published: April 2023

El crecimiento tecnológico y la necesidad de acceder a información rápidamente ha provocado que la demanda por empresas que brinden un servicio de internet ágil y eficiente incremente, provocando incertidumbre en estas empresas por ser mejores que la competencia y retener al consumidor. El desarrollo metodológico se llevó a cabo por medio de una investigación descriptiva con enfoque cuantitativo. Se recolectó 402 datos en la Provincia del Azuay. Para el análisis de resultados se realizó regresiones lineales simples y compuestas que permitieron analizar la influencia sobre la intención de cambiarse de proveedor. Los hallazgos encontrados evidencian que la percepción de riesgo de la empresa incide de manera positiva en los consumidores al querer cambiarse de proveedor, mientras que la percepción de la calidad de marca no tiene significancia sobre su intención de compra; sin embargo, cuando éstas se evalúan en conjunto, su impacto sobre la intención de compra es positiva.
Palabras clave: Calidad, empresa, Intención de compra, percepción, riesgo.
AbstractTechnological growth and the need to access information quickly have caused the demand for companies that provide agile and efficient Internet service to increase, causing uncertainty in these companies for being better than the competition and retaining the consumer. The methodological development was carried out through a descriptive investigation with a quantitative approach. Four hundred two data were collected in the Province of Azuay. For the analysis of results, simple and compound linear regressions were carried out, which allowed us to analyze the influence on the intention to change providers. The findings show that the company’s risk perception positively affects consumers when they want to change suppliers, while the perception of brand quality has no significance on their purchase intention; however, when they are evaluated together, their impact on purchase intention is positive.
