Authors: Artiukhina M.V.
Published: December 2022

The article summarizes the theoretical provisions and provides practical recommendations regarding the application of the Kanban method in the management of the preparation of student theses in a higher education institution. The conditions, advantages, principles and features of the application of flexible methodologies in the management of the preparation of student theses in a higher education institution are defined. When applying the Kanban methodology, a system of "extracting" tasks for supervisors of diploma theses is used, which is ensured by visualization of the flow of consultations provided to students, limitation of the number of unfinished tasks, and an even flow of the results of each stage of the student's work.

The Kanban methodology ensures the efficiency of the thesis management process: it contributes to a clear distribution of tasks (executors concentrate only on the current work, the amount of redundant communications decreases); transparency of all processes of the thesis; ability to monitor and control at any time; visibility; the ability to measure various elements and processes during the completion of thesis work; scaling.

Authors: Rađa Klara , Vukomanović Anja , Panjkota Krbavčić Ines
Published: December 2022

Prevalencija poremećaja hranjenja u mladih ljudi u stalnom je porastu, što dovodi u fokus ortoreksiju nervozu, osobito u razdobljima pandemije i stresa. Stoga je cilj ovog istraživanja bio utvrditi prevalenciju ortoreksije nervoze u mladih ljudi i povezati je s antropometrijskim parametrima, prehrambenim navikama i percepcijom tjelesnog izgleda. Ovo istraživanje uključivalo je 191 ispitanika u dobi od 18-24 godine, od čega je 85,9 % ženskog spola. Prikupljeni su podaci o tjelesnoj masi i visini ispitanika iz kojih je izračunat indeks tjelesne mase. Prevalencija ortoreksije nervoze procijenjena je pomoću upitnika ORTO-15, dok je upitnik PACS-R (eng. Physical Appearance Comparison Scale – Revised) korišten za procjenu tendencije usporedbe tjelesnog izgleda ispitanika s drugim osobama. Utvrđeno je da 38,2 % ispitanika ima ortoreksiju nervozu. Nije bilo statistički značajnih razlika u indeksu tjelesne mase između ispitanika s obzirom na ortoreksiju nervozu (p=0,276). Ipak, u skupini ispitanika bez utvrđene ortoreksije prevladavali su oni s adekvatnom tjelesnom masom (89,9 %), dok je među ispitanicima s utvrđenom ortoreksijom bio veći udio pothranjenih ispitanika (8,2 %) i onih s prekomjernom tjelesnom masom (15,1 %). Ispitanicima s ortoreksijom pravilna prehrana je važnija nego ispitanicima bez ortoreksije (p=0,001), dok statistički značajne razlike u samoprocjeni kvalitete prehrane nije bilo (p=0,815). Nadalje, utvrđena je statistički značajna negativna korelacija između rezultata PACS-R i ORTO-15 (p<0,01). U konačnici, postojala je statistički značajna razlika u rezultatima PACS-R između ispitanika obzirom na utvrđenu ortoreksiju (p=0,032). Ortoreksija nervoza utvrđena je kod velikog broja ispitanika. Iako su mlade osobe koje su razvile ortoreksiju nervozu uglavnom adekvatne tjelesne mase, imaju veću sklonost uspoređivati svoj fizički izgled s izgledom drugih, što upućuje na iskrivljenu percepciju vlastitog tijela. Ovime se skreće pozornost na važnost educiranja mladih osoba o pravilnoj prehrani, posebice žena, te se potvrđuje važnost interdisciplinarnog pristupa u liječenju ortoreksije nervoze, koja bi trebala uključivati i psihološkupodršku.

Published: December 2022

School meals should encourage a varied and diverse diet, since children may eat up to three meals at school per day. The aim of this study was to assess food variety and dietary diversity among primary school children regarding the number and type of school meals. Dietary records for three non-consecutive days were used to estimate the food variety score (FVS) and dietary diversity score (DDS) of 195 children (52.3% boys) aged 8-9 years from schools in the city of Zagreb. For analysis, children were divided into 5 groups according to the number and type of school meals consumed: non-consumers (23.1%), breakfast consumers (30.3%), lunch consumers (5.6%), breakfast and lunch consumers (13.3%), and breakfast, lunch and snack consumers (27.7%). The children had an average FVS of 14.3 (12.6 - 16.7) and DDS of 5.7 (5.0 - 6.0). The food group with the highest frequency of consumption was starchy staple (99.9% of children), while legumes, seeds, and nuts were consumed least frequently (15.4%). The number and type of school meals were moderately correlated (r = 0.313, p < 0.001) with FVS and weakly (r = 0.230, p = 0.02) with DDS. In addition, children who ate breakfast and lunch or breakfast, lunch, and snack from school meals had significantly higher FVS (p < 0.001) and DDS (p = 0.027) compared to children who ate fewer school meals or ate no school meal. Children (50%) who ate breakfast, lunch, and snacks from school meals were more likely (p = 0.022) to consume dark green leafy vegetables. The number of school meals may affect the food variety and dietary diversity, with children who eat more school meals having better quality. However, the values obtained by the index suggest that both parents and school food services should provide more varied meals in terms of different foods and food groups.
Molekularni mehanizmi i morfološka obilježja autofagije
Authors: Murati Teuta , Drenški Martina , Miletić Marina , Kmetić Ivana
Published: December 2022

Autofagija je evolucijski dobro očuvan katabolički proces koji se događa u svim eukariotskim stanicama, a u kojem stanica razgradnjom oštećenih makromolekula i organela, između ostalog, osigurava hranjive tvari i energiju za održavanje vitalnih funkcija. Radi održavanja homeostaze, autofagija se na bazalnoj razini odvija neprestano u gotovo svim stanicama. Različiti fiziološki podražaji (oštećenja organela, nakupljanja proteinskih agregata, hipoksija, oksidacijski stres, upala i dr.) induciraju proces autofagije. Ipak, dokazano je da su nedostatak nutrijenata i energetski stres najsnažniji regulatori procesa autofagije. Pokretanjem autofagije stanice se „brane“ recikliranjem hranjivih sastojaka i/ili razgradnjom oštećenih organela. Uslijed prekomjerne eliminacije organela i citoplazmatskog sadržaja, prekomjerne mitofagije (selektivne razgradnje mitohondrija) i posljedičnog nedostatka energije, aktivacija autofagije može rezultirati i staničnom smrću (tzv. stanična smrt ovisna o autofagiji). Istraživanja su ukazala na važnost autofagije u očuvanju zdravlja kod bakterijskih i virusnih infekcija, karcinoma, neurodegenerativnih, metaboličkih i upalnih bolesti. Pojam autofagije najčešće se odnosi na najviše istražen oblik autofagije - makroautofagiju. Osim o tom obliku autofagije, u ovom preglednom radu dan je uvid u mehanizme i obilježja mikroautofagije i autofagije posredovane šaperonom (CMA).

Pencils of Frégier Conics
Authors: Odehnal Boris
Published: December 2022

For each point P on a conic c, the involution of right angles at P induces an elliptic involution on c whose center F is called the Frégier point of P. Replacing the right angles at P between assigned pairs of lines with an arbitrary angle phi yields a projective mapping of lines in the pencil about P, and thus, on c. The lines joining corresponding points on c do no longer pass through a single point and envelop a conic f which can be seen as the generalization of the Frégier point and shall be called a generalized Frégier conic. By varying the angle, we obtain a pencil of generalized Frégier conics which is a pencil of the third kind. We shall study the thus defined conics and discover, among other objects, general Poncelet triangle families.

The geometry of such quadrilateral is almost as rich as the geometry of a triangle, so there are lot of associated points, lines and conics. Hereby, the study was performed in the rectangular coordinates, symmetrically on all four sides of the quadrilateral with four parameters a, b, c, d. In this paper we will study the properties of some points, lines and circles associated to the quadrilateral. All these properties are well known, but here they are all proved by the same method. During this process, still some new results have appeared.
Problem solution analysis on finding the velocity distribution for laminar flow of a non-linear viscous flushing fluid in the annular space of a well
Authors: Nikitin Vasiliy
Published: December 2022

Modern drilling fluids are non-linear viscous media with an initial shear stress. In classical scientific works on hydromechanical modeling of drilling fluids motion in pipes and annular channels the Shvedov – Bingham approximation and Ostwald – de Waale power-law model were used, which did not fully account for behavior of technological fluids in a wide range of shear rates. This article presents a numerical solution for a mathematical model of drilling fluid motion of the three-parameter Herschel – Bulkley rheological model in the annular space of the well. The Herschel – Bulkley model in the rheological equation takes into account the presence of initial shear stress and a tendency for viscosity to change with shear rate, which distinguishes it from the Ostwald – de Waale and Shvedov – Bingham models. The target function in solving the equation of motion is the velocity distribution in the radial direction of the upward flow of the flushing fluid. The analysis of obtained solution is based on the theory of velocity profile influence on quality of cuttings removal during wellbore cleaning. Due to peculiarities of mathematical statement of the task, which supposes necessity of differential equation of motion solution, Wolfram Mathematica computational software has been used as a calculation tool. The analysis of numerical solution allowed to draw conclusions about the possibility of its application in evaluation of velocity profile when drilling fluid moves in annular space of the well. The possibility for application of modified excess coefficient as a relative quantitative parameter for evaluation of velocity profile uniformity was substantiated.

Published: December 2022

The article presents a theoretical and experimental substantiation of the method of directional unloading of the reservoir in fields with low-permeability reservoirs. The relevance of the article is due to the reduction of hydrocarbon resources in modern conditions and the need to create new efficient environmentally friendly technologies to develop hydrocarbon deposits with hard-to-recover reserves, primarily with low-permeability reservoirs. The results of a theoretical study of the stress-strain state in the vicinity of a well, both cased and open, are presented. They are necessary to develop programs for laboratory testing of core specimens from the studied fields. A technique for physical modelling of deformation processes in the bottomhole zone with a decrease in pressure at the well bottom in a true triaxial loading unit is described in order to determine the parameters of the process impact on the formation reservoir, leading to an increase in well productivity. The method was applied to the conditions of the low-permeability reservoir at the Verkhneviluchanskoye oil and gas condensate field in the southwest of the Republic of Sakha (Yakutia). Expe-rimental studies were carried out on a unique scientific unit for true triaxial loading, created at the IPMech RAS, the Triaxial Independent Loading Test System. The directional unloading method was adapted for the studied field, the process parameters of successful application of the method were determined: the bottomhole design, the drawdown values necessary to increase the permeability of the bottomhole formation zone.

Authors: Yuwanto Mahmud Ady
Published: December 2022

Background: the nurse scheduling problem (NSP) is a serious and complex challenge in the medical industry. Effective, efficient, and high-quality services must be carried out by nurses in hospitals.Purpose: the goal of the systematic review was to find out how nurses have a positive impact on shift schedules on professional nurses in hospitals.Methods: employed the PRISMA approach. Electronic search engines from Proquest, Science Direct, and Ebsco were used to locate pertinent publications. Only English-language publications released between January 1, 2019 and December 31, 2021, had an inpatient hospital focus.Results: after identifying 265 references initially, duplicates were eliminated, and then authors from 6 pertinent papers were chosen. Overall, nurses reported that 12-hour shifts had a favorable impact on retention, including "the ability to retain experienced staff." Most nurses are flexible, don't get too tired, and will respond to patient requests like "better handoff" and "improvement of morale", Conclusion: Given that shift nurses are supposed to work about 37 hours per week and that 12-hour shifts are popular (i.e., three shifts of 12-hours). Nurse managers may think about taking action to assist nurses in reducing potential job stress brought on by the need to work shifts in order to maintain patient care. More investigation is required.

Authors: Low Mei Peng , Memon Mumtaz Ali
Published: December 2022

BACKGROUND: Amid the mounting COVID-19 situation, we take up the opportunity to examine micro-level CSR practices as an internal strategic approach for employees’ engagement to assist organizational resiliency. Past research had documented the Matthew effects of engaged employees and the fatal threat of disengaged employees. However, little is known to the precise outcome of job engagement and organizational engagement. OBJECTIVE: This study endeavors to offer comprehensive findings on job engagement and organizational engagement through the antecedent of micro-level CSR practices. Additionally, job engagement was modelled as the mediator between micro-level CSR practices and organizational engagement. Stakeholder Theory, Social Exchange Theory and Engagement Theory guided the development of the hypotheses. METHODS: Quantitative judgmental sampling technique was employed to reach out to the targeted respondents. A total of 336 responses was collected for statistical analysis facilitated by partial least squares structural equation modeling (PLS-SEM) approach. RESULTS: The study revealed that employees’ involvement and working environment are positively influencing job engagement and organizational engagement while the others micro-level CSR practices demonstrated mixed results. Also, job engagement was found to mediate the relationships between the four dimensions of micro-level CSR practices (i.e., employees’ involvement, employees’ empowerment, work-life balance and working environment) and organizational engagement. CONCLUSIONS: Micro-level CSR practices positively affecting job engagement and organizational engagement with different degree of influences. Organizations could consider implementing micro-level CSR practices for enhanced job engagement and organizational engagement to ease the challenging moment during uncertainty.
A probability of detection model for a sensor-based monitoring method against local wall thinning
Authors: Song Haicheng , Yusa Noritaka
Published: December 2022

In this study, a multivariable probability of detection (POD) model is developed to quantify the detection capability of a low frequency electromagnetic (LFEM) testing method with permanently installed sensors to monitor the thinning of pipe walls. Numerical simulations are utilized to predict the signal response by modeling LFEM testing against local wall thinning with different profiles. By probabilistically calibrating the simulated signal response with a limited number of experimental samples, signal response distributions due to various flaw profiles are inferred. Subsequently, a model is developed using Monte Carlo simulation to determine the distribution of the signal response affected by sensor placement and to calculate the POD. The resultant POD contours reflect the effect of multiple flaw parameters and sensor placement on the detection capability of the LFEM testing method.
Efficiency improvement of a high-speed permanent magnet excited synchronous machine by the use of spot-welding as lamination packaging technology
Authors: Ukwungwu David , Leuning Nora , Hameyer Kay
Published: December 2022

In this paper, an efficiency improvement of a high-speed permanent magnet excited synchronous machine (PMSM) by the use of spot-welding as lamination packaging technology is realized. Welding, interlocking, clinching and gluing are typical technologies to manufacture electrical steel stacks of electrical machines. However, these processes deteriorate the magnetic properties of the steel sheets, thereby decreasing the overall efficiency of the machine. Variations of line-welding (six, eight, twelve, thirty two and forty) line welds and spot-welding procedure is performed and analyzed. A semi-physical iron loss separation approach is used to extract the IEM iron loss model (Eggers et al., IEEE Transactions on Magnetics48(11) (2012), 3021–3024). These parameters are utilized during the finite element simulation to calculate the effective iron loss (efficiency) of the machine while using each joining procedure. A low speed, high-speed and WLTC-c3 driving cycle is exemplarily used to analyze the effects of each procedure on the machine efficiency at the different operating conditions.

Authors: Chen Xiaoyu , Leng Yonggang , Sun Fei , Su Xukun , Sun Shuailing , Xu Junjie
Published: December 2022

A novel Triple-magnet Magnetic Dynamic Vibration Absorber (TMDVA) with Eddy Current Damping (ECD) and Coulomb damping is proposed in this paper. A multi-storey structure is selected as the vibration reduction object. First, the equivalent dynamics model of the TMDVA multi-storey structure vibration reduction system is established. Then the nonlinear magnetic force model is built according to the magnetizing current theory. Next, an ECD accurate calculation model is developed and derived based on Faraday’s law of electromagnetic induction. Because of the model, the ECD coefficient can be designed and adjusted arbitrarily. The full text indicates that adjusting the ECD coefficient properly can not only improve the vibration reduction effect of the TMDVA, but also reduce the sensitivity of the vibration reduction effect to the excitation amplitude as well as enhance the broadband vibration reduction performance and the robustness of the TMDVA. With its simple structure, the TMDVA is easy to be implemented and miniaturized. And the low frequency vibration reduction effect of the TMDVA is better than other existing magnetic dynamic vibration absorbers. Taken together, the TMDVA has potential application value in passive vibration reduction of engineering structures.
A novel grounding mode for enhancing current rating of AC submarine cables
Authors: Cai Runze , Yang Shiyou
Published: December 2022

Due to the deficiency in using the cross-bonded grounding mode, a large circulating current is usually induced in the metal sheaths and armors, reducing the permissible current rating of submarine cables. To address this issue, this paper proposes a novel grounding mode to suppress these circulating currents and enhance the permissible current rating within the voltage limits of metal sheaths and armors. To achieve the best performance of the novel grounding mode, the optimal grounding impedances are given. Theoretical analyses indicate that for general submarine cables, the novel grounding mode can suppress the circulating currents within the voltage limits compared with the two-ends grounding mode, and can reduce the short-circuit terminal voltage of metal sheaths and armors compared with the non-interlinked version of the proposed mode. The numerical results further validate the better comprehensive performances of the novel grounding mode in reducing the power loss and short-circuit overvoltage.
Research on electronic nose for compound malodor recognition combined with artificial neural network and linear discriminant analysis
Authors: Liu Weiling , Liu Ping , Han Furong , Xiao Yanjun
Published: December 2022

The foul odor of foul gas has many harmful effects on the environment and human health. In order to accurately assess this impact, it is necessary to identify specific malodorous components and levels. In order to meet the qualitative and quantitative identification of the components of malodorous gas, an electronic nose system is developed in this paper. Both principal component analysis (PCA) and linear discriminant analysis (LDA) were used to reduce the dimensionality of the collected data. The reduced-dimensional data are combined with a support vector machine (SVM) and backpropagation (BP) neural network for classification and recognition to compare the recognition results. Regarding qualitative recognition, this paper selects the method of LDA combined with the BP neural network after comparison. Experiments show that the qualitative recognition rate of this method in this study can reach 100%, and the amount of data after LDA dimensionality reduction is small, which speeds up the pattern speed of recognition. Regarding quantitative identification, this paper proposes a prediction experiment through Partial least squares (PLS) and BP neural networks. The experiment shows that the average relative error of the trained BP network is within 6%. Finally, the experiment of quantitative analysis of malodorous compound gas by this system shows that the maximum relative error of this method is only 4.238%. This system has higher accuracy and faster recognition speed than traditional methods.

Published: December 2022

Design knowledge is critical to creating ideas in the conceptual design stage of product development for innovation. Fragmentary design data, massive multidisciplinary knowledge call for the development of a novel knowledge acquisition approach for conceptual product design. This study proposes a Design Knowledge Graph-aided (DKG-aided) conceptual product design approach for knowledge acquisition and design process improvement. The DKG framework uses a deep-learning algorithm to discover design-related knowledge from massive fragmentary data and constructs a knowledge graph for conceptual product design. The joint entity and relation extraction model is proposed to automatically extract design knowledge from massive unstructured data. The feasibility and high accuracy of the proposed design knowledge extraction model were demonstrated with experimental comparisons and the validation of the DKG in the case study of conceptual product design inspired by massive real data of porcelain.

Background:

Cognitive behavioral therapy (CBT) reduces anxiety symptoms in patients with Parkinson’s disease (PD).

Objective:

The objective of this study was to identify changes in functional connectivity in the brain after CBT for anxiety in patients with PD.

Methods:

Thirty-five patients with PD and clinically significant anxiety were randomized over two groups: CBT plus clinical monitoring (10 CBT sessions) or clinical monitoring only (CMO). Changes in severity of anxiety symptoms were assessed with the Parkinson Anxiety Scale (PAS). Resting-state functional brain MRI was performed at baseline and after the intervention. Functional networks were extracted by an Independent Component Analysis (ICA). Functional connectivity (FC) changes between structures involved in the PD-related anxiety circuits, such as the fear circuit (involving limbic, frontal, and cingulate structures) and the cortico-striato-thalamo-cortical limbic circuit, and both within and between functional networks were compared between groups and regressed with anxiety symptoms changes.

Results:

Compared to CMO, CBT reduced the FC between the right thalamus and the bilateral orbitofrontal cortices and increased the striato-frontal FC. CBT also increased the fronto-parietal FC within the central executive network (CEN) and between the CEN and the salience network. After CBT, improvement of PAS-score was associated with an increased striato-cingulate and parieto-temporal FC, and a decreased FC within the default-mode network and between the dorsal attentional network and the language network.

Conclusion:

CBT in PD-patients improves anxiety symptoms and is associated with functional changes reversing the imbalance between PD-related anxiety circuits and reinforcing cognitive control on emotional processing.

Published: December 2022

Knowledge Graphs are currently created using an assortment of techniques and tools: ad hoc code in a programming language, database export scripts, OpenRefine transformations, mapping languages, etc. Focusing on the latter, the wide variety of use cases, data peculiarities, and potential uses has had a substantial impact in how mappings have been created, extended, and applied. As a result, a large number of languages and their associated tools have been created. In this paper, we present the Conceptual Mapping ontology, that is designed to represent the features and characteristics of existing declarative mapping languages to construct Knowledge Graphs. This ontology is built upon the requirements extracted from experts experience, a thorough analysis of the features and capabilities of current mapping languages presented as a comparative framework; and the languages’ limitations discussed by the community and denoted as Mapping Challenges. The ontology is evaluated to ensure that it meets these requirements and has no inconsistencies, pitfalls or modelling errors, and is publicly available online along with its documentation and related resources.

Authors: Hanafy Sara , Colantonio Angela , Mollayeva Tatyana , Munce Sarah , Lindsay Sally
Published: December 2022

BACKGROUND: Traumatic brain injury (TBI) impacts an individual’s workforce involvement post-injury. Support services and workplace accommodations that can help with work re-integration post-TBI may differ based on a person’s sex and gender. The added impact of COVID-19 remains under-explored. OBJECTIVE: We aimed to investigate the support services and workplace accommodation needs and the impact of COVID-19 on work and mental health for persons with TBI, considering sex and gender. METHODS: A cross-sectional online survey was distributed. Descriptive and regression analyses were applied to uncover sex and gender differences, along with content analysis for open-ended responses. RESULTS: Thirty-two persons with TBI (62% women, 38% men) participated. Physiotherapy, occupational therapy, and counselling services were indicated as the most needed services by women and men. Modified hours/days and modified/different duties were the most needed workplace accommodations. Mental challenges impacting well-being was a highlighted concern for both men and women. Women scored poorer on the daily activity domain of the Quality of Life after Brain Injury – Overall Scale (p = 0.02). Assistance with daily activities was highlighted by women for a successful transition to work, including housekeeping and caregiving. Men were more likely than women to experience change in employment status because of COVID-19 (p = 0.02). Further, a higher percentage of men expressed concern about the inability to pay for living accommodations, losing their job, and not having future job prospects. CONCLUSION: Findings reveal important differences between men and women when transitioning to work post-TBI and emphasize the need for sex and gender considerations.

X-ray optics with good focusing ability and high spectral resolution are required in X-ray spectroscopy for the diagnosis of high temperature and density plasmas. In our study, a novel X-ray spectrometer is developed to provide the ability to record spectra with excellent focusing performance and high energy resolution. It is accomplished by using a continuously conical crystal (CCC) that is formed by circles with different curvatures. In this paper, we present the foundational work of the design and development of continuously conical crystal spectrometer (CCCS) along with initial results obtained with a titanium (Ti) target as the object source. First, the spectrometer based on such a continuously conical crystal is used to measure X-ray spectra on Ti target X-ray Tube device. The spectral resolution (λ/Δλ) is around 615 with the source size of 1 mm. Then, we test the capability of the spectrometer on Xingguang-III Laser Facility with Ti target. He-like and Li-like Ti lines are recorded based on which the spectrometer performance is evaluated. The experiment result shows that the spectrometer provides a high spectral resolving power up to 1000, while acquiring a one-dimensional image of the source.

acute pesticide poisoning is a global health problem. According to the WHO, poisoningby chemicals, including chemical plant protection products, is a leading non-communicable disease.Violation of the rules for working with pesticides leads to the occurrence of occupational diseasesamong workers. Therefore, compliance with pesticide regulations and the use of personal protective equipment is a very important preventive measure. The purpose of our work: to predict the occur-rence of acute toxic effects in workers who treat berry and melon crops with pesticides. Research materials and methods: to assess the probability of acute toxic effects among workers who deal withactive substances and preparations based on them. We calculated three indicators: the coefficient of possible inhalation poisoning (DSanPiN 8.8.1.002-98), the selectivity of pesticides by inhalation pes-ticides and the selectivity of pesticides under dermal exposure according to the method of Sergeeva S.G. Results: according to the “Hygienic classification of pesticides by degree of danger” DSanPiN8.8.1.002-98 all tested active substances belong to the 4th class of danger according to the coefficientof possible inhalation poisoning, which was less than 0,5. The coefficient of selectivity of the actionof pesticides during inhalation exposure to active substances was in the range of 7,41 – 1000,0. For cyprodinil, phenhexamid, azoxystrobin, pyraclostrobin, copper chloride, pendimethalin, S-me-tolachlor, glyphosate, and abamectin, it was less than 100, indicating their relatively low selectivity of action. Other studied active substances had a high selectivity of action, since this coefficient was more than 100. It was established that all studied drugs have sufficient selectivity of action when in-haled. The coefficient of selectivity for dermal exposure was more than 100 for all the studied active substances, except for S-metolachlor and glyphosate. Preparations Trinol, VG, Signum, VG, RidomilGold R 161 WG, VG, Stomp Aqua, SK, Dual Gold 960 EC, KE, Herbolex v.r. have low selectivityof action when entering through the skin, all other pesticides have sufficient selectivity of action. Theobtained data indicate that all the active substances under study are not dangerous (hazard class 4),according to DSanPiN 8.8.1.002-98. Therefore, when working with these substances you need tofollow hygienic regulations.
Protection sociale contributive, revenu transitoire et accès aux services sociaux de base en République Démocratique du Congo, cas des retraités affiliés à la Caisse Nationale de Sécurité Sociale

Cet article étudie la relation existante entre protection sociale contributive, revenu transitoire et accès aux services sociaux de base en République Démocratique du Congo, cas des retraités affiliés à la Caisse Nationale de Sécurité Sociale. L'étude utilise la technique des moindres carrés ordinaires (MCO). Les tests usuels ont conclu que le modèle estimé est bon, puisque les hypothèses de moindres carrés ordinaires ont été minutieusement respectées.

Les résultats du modèle retenu indiquent que : (i) les revenus disponibles de ménages ainsi que la pension de retraite ne couvrent pas totalement les dépenses de consommation, bien que les deux coefficients sont positifs, (ii) les revenus générés par les AGR ne couvrent pas totalement les dépenses de consommation, et présente un signe négatif, (iii) la taille de ménage n’impacte pas les dépenses de consommation, bien que le coefficient est positif. Cela peut être expliqué par des prestations sociales modiques, incomplètes, réduites en termes de couverture.

 D’où les ménages des retraités doivent recourir probablement à l'emprunt afin de faire face à leur consommation, et, solutions hors marchés comme le transfert entre ménages, une solidarité pouvant permettre à certains ménages de survivre.

CAN ASSESSMENT BE A MOTIVATIONAL FACTOR IN FOREIGN LANGUAGE LEARNING?
Authors: Sovhar Oksana , Sovhar Hanna , Antoniv Iryna
Published: December 2022

Тhe article considers the influence of assessment of students’ foreign language communicative competence on their motivation to master a foreign language. The authors of the article analyzed modern forms of assessment used to increase students’ motivation while learning a foreign language; compared the opinions of teachers and students on effective types of assessment of foreign language communicative competence; identified strategies which proved effective to motivate students to study foreign language on a regular basis. The purpose of the study was to examine possible causal connections between introduction of high level formative assessment and motivation of students to study foreign languages. It has been established that while employing high level formative assessment teacher takes into account diiferent level of students’ language proficiency, directs their efforts in mastering a Vjforeign language and provodes positive feedback. Such assessment is meant to be a process aimed to provide information that teachers can utilize to tailor instruction in order to meet students’ needs so that students can progress more in their learning. Here teachers have important tasks of establishing rapport and collaboration with students thus making them aware of their learning achievememts based on comprehensible criteria and objectives as well as delivering constructive feedback while assessing and evaluating. It is also essential to create an atmosphere in which students will be active participants of learning, not afraid of making mistakes and taking responsibilities for their successes and failures. The results of the study confirmed the research hypothesis that higher level formative assessment serves to enhance students’ motivation to learn a foreign language and has a significant impact on the development of foreign language communicative competence.

Strengthening the position of the Ukrainian state in the international arena, recognition of its role in maintaining global security and stability, deepening its integration into the Euro-Atlantic and world community raises to a new level the need to train highly qualified specialist translators, whose professional competencies would meet the requirements of modernity and the growing needs of our country. In the short term, due to the involvement of foreign governments, international organizations and private companies in the post-war reconstruction of Ukraine, the number of our international contacts at at all levels will increase rapidly. This means that that future specialists will not only have to search for and correctly use common equivalents of English place names, atroponyms, ergonyms, but also often reproduce them themselves, or rather create Ukrainian equivalents for specific English-language cultural realities, and vice versa. Thus, the expansion of international cooperation in economic, political, military, security cultural, educational, environmental and many other spheres of life, necessitates the creation of new modern textbooks and translation manuals. Such is the peer-reviewed textbook by D. P. Borys "Onomastic Aspects of Translation: Theory and Practice".
Granular cell ameloblastoma: A rare and unique variant
Authors: Sukumaran Renu , Somanathan Thara , Sen Anitha
Published: December 2022

Ameloblastoma is a slow-growing and locally invasive epithelial odontogenic tumor of the jaw that runs a benign course in most cases. Granular cell ameloblastoma is a rare subtype of ameloblastoma, showing the granular transformation of its cytoplasm. It is considered as an aggressive variant of ameloblastoma. Herein, we report the case of a 34-year-old male patient who presented with a swelling in the left cheek for a 1-year duration with a recent rapid increase in size. Examination showed a 4 × 3 cm growth involving the left buccal mucosa and retromolar area. Imaging studies showed expansile lytic lesion mandible. Biopsy revealed neoplasm with odontogenic epithelial islands showing peripheral palisading of tall columnar cells with reversal of polarity and the center of the islands showing stellate reticulum-like cells which were markedly replaced by granular cells. Granular cells can appear in various odontogenic and non- odontogenic tumors. When there is extensive granular cell change in ameloblastoma, it should be differentiated from other oral lesions with granular cells including granular cell odontogenic tumor, granular cell tumor, and congenital epulis.Herein we report the case of a 34-year-old male patient presented with swelling left cheek of one-year duration with recent rapid increase in size.
