movement difficulties used by individual elite senior rhythmic gymnasts in their routines. In the World Cup Competitions and European Championships held in 2021, the final competition routines (N=75) of gymnasts (N=28) were examined, and body and apparatus difficulties, and the number and rate of use of the preferred side were determined. Since gymnasts participated in more than one competition, their most recent competition routines were included in the research. The data were obtained by analyzing the routines recorded during the competitions. Explanatory statistical analyses of the data were conducted by using the IBM SPSS 25.0 statistical program. In all routines, while higher rates of between 56.2% and 87% were found in the right hand when compared to the left hand in throwing and catching, higher rates were found in the hoop and ribbon apparatus in throwing with the left foot when compared to the right foot. In the right foot/leg catches, the highest rates were observed in the hoop apparatus (49.6%). Left foot usage preferences were observed at rates varying between 65.1% and 97.4% in jumps/leaps difficulties and between 58% and 71% in balance difficulties. In rotation difficulties, the use of the right foot had higher rates of between 72.6% and 80% when compared to the left foot. Gymnasts showed a tendency to use the right hand predominantly in throws and catches, the left foot in jumps/leaps and balances, and the right foot in rotations.

However, the approach to designing laboratory stands for training students and electrical personnel on the specifics of using digital protections in most cases has remained the same, which does not allow for fully realizing their potential. The purpose of the work is to improve the quality of the knowledge and practical skills received by students in the work with digital protection blocks. To achieve the goal, a specialized laboratory stand for testing digital security terminals has been developed. The stand consists of a mathematical model of the protected object, implemented in the form of a computer program and hardware, which allows real-time conversion of changes in model mode parameters into physical signals transmitted to the digital protection device. The stand provides the terminal feedback with the model, which makes it possible to study the protection behavior in the characteristic operating modes of the protected element. The protection of the "line-transformer" block using the Siprotec 4 7SJ6 Siemens terminal is considered. It is possible to calculate the protection operation parameters, configure the digital protection device, and also check the correct operation of the protections by automatically simulating normal and emergency operation modes of the protected object. The software and hardware of the stand makes it easy to expand its capabilities by adding new models of power system objects and other digital protection devices. The equipment used in the developed stand does not require significant capital investments, which makes this approach accessible to higher educational institutions.

Published: February 2023

The current development of the power industry involves various kinds of FACTS, being element of the Smart Grid and controlled by power electronics used for increasing the flexibility of electrical networks. Thus, the development and research of such devices are relevant. The study object is a controller belonging to the "Sen" family of transformers, which provides regulation of voltage and power flows in networks. The aim of the work is to study the balancing properties of booster transformer, which has an extended range and higher control accuracy in various modes. The goal was achieved during research carried out on the basis of structural simulation models. The most significant result was statement that the device under study has a pronounced per-phase balancing effect, which is preserved in various modes, including reverse ones. The main result can be consider that the proposed device, in comparison with the currently existing transformers of the "Sen" family, due to the extended range and accuracy of voltage regulation, allows using it when working, both for symmetrical and asymmetric loads. It is shown that the proposed technical solution provides ample opportunities for longitudinal-transverse phase-by-phase voltage regulation. Moreover, the deviations of parameters characterizing the quality of electricity, such as modules and voltage angles, do not go beyond the limits regulated by the requirements of the standard. The results obtained allowed us to conclude that this device can be used to solve the problem of coordinating the operation of two asymmetric systems in different operating modes.

The goal of the work is to expand the frequency range of operation of coplanar waveguide transmission lines as broadband high-speed superconducting protection devices against powerful ultrashort electromagnetic radiation, and to apply them in antenna devices of radio electronic systems designed to ensure the reliable operation of critical infrastructure facilities. The aim is achieved by solving the following tasks: investigating the electrophysical properties of coplanar transmission lines, in particular, capacitance, surface and wave resistance in different phase states that arise under the influence of powerful electromagnetic radiation, and determining the main factors for effective protection in a wide frequency range, designing protective devices. The most important result is the establishment of the possibility of using coplanar transmission lines as protection devices in a wide frequency range up to 100 GHz, as well as the establishment of the dependence of their main characteristics on the design parameters of the superconducting protection device. The significance of the obtained results consists of solving a complex problem of providing protection of antenna systems against powerful ultrashort radiation by establishing an analytical relationship between the electrophysical parameters of coplanar waveguide transmission lines, which are in different phase states determined by the influence of powerful electromagnetic radiation, and their design parameters. The peculiarity of the obtained results is in the clarification of the dependence of the wave resistance of the coplanar waveguide transmission lines in superconducting, mixed, and normal phase states on the change of their active component of surface resistance, determined in turn by the design characteristics of the protective device. The difference from the known works lies in obtaining relationships for determining the wave resistance of protective devices in different phase states.

Authors: Verejan Victoria , Bendelic Eugeniu , Bernic Jana
Published: February 2023

Background: Visual disturbances may result in a long-term complication after mild traumatic brain injury (mTBI) in children. These problems may affect both near work and reading, and thus affect activities of daily life and the child’s return to school activity. The purpose of the study was to assess the visual acuity disturbances and refractive status in children with persisting symptoms after mild traumatic brain injury. Material and methods: Forty-eight patients with persisting symptoms after mild traumatic brain injury and anomalies of visual acuity were included. Visual symptoms and refractive status were assessed during the eye examination. Results: Thus, in the mTBI group the visual acuity for the right eye was of 0.09-0.5 in 83.7% (40 patients), in 16.3% (8 patients) – right eye 0.6-0.8, comparing to the control group, where 62% patients had the visual acuity ranged almost in 1.0, just 14% (7 patients) ranged 0.09-0.5 and in 24% (12 patients) – 0.6-0.8. The visual acuity for the left eye in the research group was of 0.09-0.5 in 89.8% (43 patients), in 10.2% (5 patients) – for the left eye was 0.6-0.8, comparing to the control group, where 66% patients had the visual acuity ranged almost in 1.0, just 24% (12 patients) it ranged 0.09-0.5 and in 14% (5 patients) – 0.6-0.8. Conclusions: Visual acuity (VA) is affected primary after head trauma although it has big chances to get better with a vision therapy in a time period ranged between 3 and 6 months after the trauma. In most of the cases, we speak of a blurred vison in the near work and relative unclear perception at far. Autorefraction data usually will reveal a slight hyperopia with a possible astigmatic component ranged between 1D to 3D, and in 4.1%-8.2% of cases a slight myopia referring to the spherical compound and 18.4%-32.7% astigmatic compound, also ranged between 1D and 3D.

Published: February 2023

Background: Despite the progress made in the study of psoriasis and psoriatic arthritis, their early diagnosis and treatment for practicing physicians continue to be a difficult problem. Material and methods: 100 people were examined, including 70 patients with psoriatic arthritis aged between 18 and 60 years (23 men and 47 women), admitted to the rheumatology and arthrology departments of the Timofei Mosneaga Republican Clinical Hospital 2019-2022 (Favorable opinion of the Committee for Research Ethics, No 21 of 21.12.2019). The control group included 30 people with rheumatoid arthritis. Results: Ultrasound signs of damage to the joint structures were detected, such as synovitis (p=0.26), cartilage changes (p=0.433), enthesopathy (p=0.980) and tenosynovitis, statistically significant differences (p=0.800). Magnetic resonance imaging determined that fluid was the predominant symptom in frequency (n=13, 92.86%), including in the small joints of the hands (n=1, 100%) and feet (n=2, 100%). Conclusions: In large joints, the proliferation of the synovial membrane was detected in 51.67% of the joints and had predominantly high echogenicity. At small joints, synovial proliferation with predominantly low echogenicity occurred only in 6.1% of the joints.

Published: February 2023

Background: Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. The patient who does not respond to the empiric antisecretory treatment, with alarming symptoms, or referred to surgery should undergo an esophagogastroduodenoscopy (EGD). Material and methods: This was a retrospective and descriptive study of patients with GERD admitted for antireflux laparoscopic surgery from 2012 to 2019. All endoscopic data were analyzed with the following variables: age, gender, reflux esophagitis and its severity, esophageal ulcers and strictures, Shatzky’s ring, Barrett’s esophagus (BE), incompetence of the esogastric junction; hiatal hernia. Results: A total of 152 patients were included in the study. The age of the patients ranged from 19 to 76 years, averaging 52 years. Among them, 97 (63.8%) were women and 55 (35.38%) men. A wide variety of endoscopic features has been found: non-erosive GERD (6.57%); reflux esophagitis (Savary-Miller) – I (21.05%), II (44.07%), III (23.68%); esophageal ulcer (1.31%), BE (1.97%). The majority of patients present axial hiatal hernia (92.76%) corresponding to Hill grade IV incompetence of the flap valve. Hill grade III was present in 4.6% of cases, grade II – 2.63%. Conclusions: The patients with GERD may have a wide range of endoscopic features (from normal to esophagitis, hiatal hernia, strictures and EB). Considering the multitude of data provided by endoscopic examination in patients with GERD, it can be certainly stated that EGD is one of the most important investigations in these patients, and is mandatory in those selected for surgical treatment.
Comparative analysis of imaging investigations in the diagnosis of retroperitoneal tumors
Authors: Schiopu Victor , Scerbatiuc-Condur Corina , Ghidirim Nicolae
Published: February 2023

Background: Primary retroperitoneal tumors (PRT) are a group of extremely heterogeneous soft tissue tumors that grow in the retroperitoneal space and have no organic affiliation. Tumors usually become symptomatically late and cause secondary symptoms or become palpable once they have become significantly large. Preoperative diagnosis of PRT is essential for assessing subsequent treatment tactics, planning the approach and volume of surgery, by detecting the structural component, relationships with adjacent anatomical structures and the degree of invasion. Material and methods: Complex prospective and retrospective analysis of clinical, anamnestic and imaging data of 118 patients with primary and nonprimary retroperitoneal tumors, investigated and treated at the Institute of Oncology of the Republic of Moldova during 2015-2020. Results: To determine the primary PRT diagnosis for the clinician, it is primordial to rule out the organic or secondary nature of the tumor. Thus, the patients were examined by: abdominal USG – 118 patients (100%), abdominal and small pelvic contrast-enhanced CT – 118 patients (100%), MRI – 3 patients (2.5%), videoesogastroduodenoscopy – 32 patients (27.1%), videocolonoscopy – 31 patients (26.3%), irigography – 4 patients (3.4%), urography – 29 patients (24.6%). Conclusions: Contrast-enhanced CT provides more accurate data than USG. The image obtained at the USG examination is flat, therefore the dimensional measurements of the tumor are not always performed on the longest tumor axis, especially in the case of polylobulated or giant tumors, while the tomographic examination techniques allow the three-dimensional reconstruction of the tumor with more accurate assessment of the tumor size.
Overview on possible causes of COVID-19
Authors: Draguta Ilarion
Published: February 2023

Background: The infection with the new coronavirus SARS-CoV-2 has caused a large number of cases of disease and death worldwide. Identifying the source of COVID-19 is an important issue though still unresolved. The analysis of the literature on highlighting possible sources of the SARS-CoV-2 virus was carried out. Conclusions: The COVID-19 pandemic is occurring on the underlying imminent global ecological catastrophe as a result of the anthropogenic activity. Therefore, it can be stated that Homo Sapiens in the context of the interaction with the biosphere is a maladaptive species. According to the literature, the species’ adaptive responses to environmental changes are due to endogenous retroviruses. The latter act as evolutionary factors. Possible pandemic COVID-19 is not a separate epidemic process caused by the penetration of a new virus into human populations, but rather is one of the manifestations of a more complex natural phenomenon – an evolutionary process under the guise of an infectious one. In terms of evolution, COVID-19 plays the role of a biosphere factor that seeks to help a relatively new species to adapt to the general conditions of survival in a symbiotic relationship with other living organisms.

Published: February 2023

Background: The dysfunction of the temporomandibular joint (TMJ) becomes a significant and serious problem for modern society. TMJ disorder is the pathology of the stomatognathic system that is encountered more and more often every year, because the etiology is different and the pathogenesis is not well investigated. This disease is the result of the action of many factors that are constantly related to each other and over time can intensify and aggravate each other. A large number of studies have been done, articles and scientific papers have been published on the subject to establish the degree of prevalence and severity of this disease. Every year there are more and more patients with this pathology, which would mean that an effective solution in solving this problem has not yet been found and the topic remains relevant to this day. Insufficient knowledge of the mechanisms of this disease is one of the main reasons for the ineffectiveness of the treatment methods used. The objective of the work was to identify the clinical relevance of temporomandibular joint diseases. Conclusions: TMJ dysfunction is a topic that does not lose its relevance, because it is still a problem to identify the causes of pathologies of the TMJ and their treatment. TMJ pathology can be caused by various factors, the identification of this problem should be approached with all seriousness, taking into account all diagnostic methods and a high-quality anamnesis taken from the patient.

Published: February 2023

Circadian rhythm disorders (CRD) result from modern lifestyles characterized by long exposure time to blue light, shift-work, chronic stress and night-time social activities. The disruption of circadian rhythms represents an individual risk factor in the development of various diseases, including neurodegenerative ones. Simultaneously, the demographic ageing is associated with the rising incidence of neurodegenerative diseases (ND), the cognitive decline becoming a societal problem. Thus, this literature review’s purpose is to outline the interconnexion between CRD – ND – cognitive disruptions from a pathophysiological angle based on the example of Parkinson disease. The final objective of the study is to depict what are the prophylactic measures against brain and cognitive reserve’s decline caused by CRD in order to enhance life quality by lowering the DALY index.

Published: February 2023

The circadian rhythm is an endogenous process that has a periodicity of approximately 24 hours and stimulates the anticipation of repeated and regular events that occur daily, enabling the regulation of most major physiological systems in humans and animals. Thus, studies have shown that disruption of circadian rhythm and sleep is a frequent cause of a series of pathologies for the general population, including pregnant women and their fetus. The purpose of this article is to review the literature on the relationship between circadian rhythm and sleep disorders in pregnant women and the influence on the development of the fetus, as well as the future developing adult. Pregnancy is a critical period in which the systems of organs of a new human body are developing, and any disturbance in the environment in which the fetus grows can lead to developmental disorders that alter the metabolic and physiological functions of the fetus. Thus, maintaining an undisturbed circadian rhythm, including during pregnancy, protects the health of both the mother and the child, reducing the susceptibility to the development of certain postnatal diseases later in life.
AUTONOMÍAS ANTISISTÉMICAS. DIÁLOGO ENTRE LA TEORÍA ANARQUISTA Y LA AUTONOMÍA INDÍGENA EN AMÉRICA LATINA
Authors: Makaran Gaya
Published: February 2023

El objetivo del presente ensayo es poner en diálogo los aportes de la teoría anarquista y proyectos autonómicos indígenas que venimos investigando en los últimos años, con la finalidad de enriquecer el debate sobre la autonomía en América Latina. En este sentido, propo-nemos entender la autonomía en su sentido antisistémico, claramente influenciado por la escuela libertaria del pensamiento, enfoque que nos guiará en este escrito y que será un punto de partida para nuestras re-flexiones y la columna vertebral de nuestra argumentación. Nuestro pro-pósito es pensar la autonomía como horizonte de deseo y como práctica concreta, tanto en su dimensión individual como colectiva, entendida como camino hacia la emancipación social. De ahí destacaremos sus potencialidades antiestatales y anticapitalistas, al mismo tiempo que antiautoritarias y antijerárquicas.
GENEALOGÍA DEL ESTADO Y EL DERECHO A DECIDIR
Authors: Flores Juan
Published: February 2023

Este trabajo pretende realizar una genealogía1 del Estado y el derecho a decidir, buscando unir la teoría, con la observación participante del autor en la defensa de los derechos indígenas. El Estado es un instrumento de control que actúa contracorriente a un sistema de autodeterminación de los pueblos indígenas que ha existido durante siglos. No solo es posible un Estado pluricultural, sino que existe, y el trabajo es lograr su reconocimiento en los hechos y en el derecho, a través de la redefinición de cómo se ejecuta la soberanía que reside en el pueblo. Discutir quién tiene derecho a decidir sobre quién, y el derecho de autodeterminación, es un tema de importancia trascendental en la actual crisis social, ambiental, económica, de salud y civilizatoria que estamos viviendo.
AUTONOMÍA Y PLURALISMO JURÍDICO EN LAS COMUNIDADES INDÍGENAS. UNA REFLEXIÓN DESDE LOS DERECHOS HUMANOS Y EL NUEVO CONSTITUCIONALISMO LATINOAMERICANO
Authors: Salcedo Juan
Published: February 2023

En el presente artículo se aborda el reconocimiento a la autonomía, a la libre determinación, el pluralismo jurídico y los derechos humanos de las comunidades indígenas desde el Neo-Constitucionalismo en México. Se ofrece un análisis que visibiliza la desarticulación existente entre la institucionalización de estos derechos desde el paradigma monista del Estado Constitucional de Derecho y la praxis de los procesos históricos, vivenciales e identitarios que se gestan desde el interior de las comunidades indígenas. En este sentido, se abordan los movimientos sociales indígenas como mecanismos que se articulan desde abajo, desde las propias comunidades en aras de construir procesos que constituyen exigencias, resistencias y luchas frente a las estructuras sistemáticas del Estado Constitucional de Derecho, en busca del reconocimiento institucional y materialización efectiva de la libre determinación, la autonomía, el pluralismo jurídico y sus derechos humanos desde la alteridad, la Otredad y la diversidad poblacional, logrando, así, la unión de una nación pluriversal, lo cual se pretende lograr desde las pautas del Nuevo Constitucionalismo Latinoamericano, mismas que son abordadas en el desarrollo del presente artículo.
LIBRE DETERMINACIÓN Y MEGAPROYECTOS: EL CONSEJO REGIONAL INDÍGENA Y POPULAR DE XPUJIL (CRIPX) FRENTE AL TREN MAYA
Authors: Bachelot Bianca
Published: February 2023

El presente texto parte del argumento de que, en México, la lucha por la libre determinación de los pueblos se realiza en el marco de movimientos sociales que se organizan, entre otros, debido a los conflictos socioambientales generados por las políticas públicas impulsadas por los gobiernos de corte neo desarrollistas. En ese sentido, se analizan los campos de interacción entre el estado y las organizaciones indígenas y la correlación de fuerzas entre el paradigma del neo desarrollo versus el horizonte político de la libre determinación, a partir del caso concreto de la lucha que está llevando el Consejo Regional Indígena y Popular de Xpujil (CRIPX) en contra del Tren Maya, bajo la bandera de la libre determinación. Para ello, se estudiaron varios ejes de confrontación en torno a la consulta previa, libre e informada, así como las estrategias y perspectivas para la construcción de la libre determinación a nivel local, nacional y latinoamericano.
EN LOS BORDES DE LA POLÍTICA: SUJETO Y HORIZONTES POLÍTICOS EN LA DEFENSA DEL TERRITORIO EN EL ISTMO DE TEHUANTEPEC, UN PUENTE PARA ENTENDER LAS RESISTENCIAS ANTE LOS MEGA- PROYECTOS DE LA “CUARTA TRANSFORMACIÓN”
Authors: Tripp Jorge
Published: February 2023

El artículo aborda la correspondencia entre praxis, sujeto en lucha y construcción de horizontes emancipatorios desde la experiencia del movimiento en defensa del territorio en la planicie oaxaqueña del Istmo de Tehuantepec, y la rela-ción que éste guarda ante los planes de expansión territorial del capital en la región por medio de los megaproyectos, operados bajo el gobierno de la “Cuarta Transfor-mación”. Para tal objetivo, se parte de la capacidad de insubordinación y confron-tación en la praxis del sujeto regional articulado istmeño, en oposición a su posición subordinada dentro del estado mexicano y las vías de participación política a que está constreñido. Con ello, se intenta tender un puente analítico –desde la perspec-tiva de los sujetos en lucha– con otras experiencias de luchas socioterritoriales en México, en el contexto de la llegada de un gobierno que se confiere un matiz alterna-tivo al de los que lo precedieron.

REGULATION DRIVEN (UN) ETHICAL BUSINESS PRACTICES OF SMALL OWNER MANAGED ENTERPRISES
Authors: Wei Wang , Talib Ameen
Published: February 2023

Governments use laws and regulations to point business behavior in what they perceive to be beneficial directions. Ethics implicitly regulates areas and details of behavior that lie beyond governmental control. Business ethics applies to all aspects of business conduct and is relevant to the conduct of individuals and entire organizations. These ethics originate from individuals, organizational statements or from the legal system. This paper argues that certain business regulations may drive Small-Owner-Managed-Enterprises (SOME) to engage in unethical business practices. This is not ‘beneficial direction’ for society. This paper is part of a wider research on issues and challenges facing SMEs and in particular SOME, and deals with only a small part of the current regulatory framework in Singapore.

There were flaws in sensitivity of scopes,meaning, importance and equity to all. Since performance contract is a freely negotiated tool, government should lay agood foundation and not hurried up process leading to confusion. Performance contracting is directed to all public civilservice as a reform agenda for better service delivery. Whereas the high ranking servants may welcome the idea ofmeasuring performance the lower cadre might feel exposed hence resist. Performance appraisals evaluate strengths andweakness against the criteria set upon organizations goal and therefore are worthy. Challenges in grading structure andnegotiation committee can be addressed by agreed targets. Further, in all stages communication should remain open andeliminate any ambiguities to build trust. Fair and firm government instructions with proper standards against whichresults can be measured, will lead head teachers giving key areas for good results establishment. Good leadership byhead teachers will influence teachers to willingly and enthusiastically append signatures in performance appraisals.

Authors: Abdalla Rezgalla
Published: February 2023

Although many studies have explored the shift to stakeholder corporate governance in western countries, so far there has been a lack of study, which explores whether corporate Malaysia has shifted to stakeholder corporate governance. 

Therefore, the main objective of this study is to explore whether corporate Malaysia has shifted to stakeholder corporate governance. Based on 15 interviews with board members of Malaysian listed companies, the analysis of this study was conducted, using thematic analysis through NVivo version 10. Finally, the interpretive approach was adopted as the main worldview of the study. 

The findings indicated that the practices of board members have shifted to stakeholder corporate governance primarily shareholders, employees, customers and the community. Several factors emerged as determinants of stakeholder corporate governance such as sustainability, values and ethics, corporate attributes, and individual attributes. 

This study, implicates that, current corporate governance theories such as agency theory and stakeholder theory are inadequate to explain the actual behaviors of board members regarding the practices of stakeholder corporate governance. Therefore, this study proposes a practical theory regarding stakeholder corporate governance based on the actual behaviors of board members.
