The article examines one of the urgent problems of preschool education at the present stage - the problem of introducing an interactive technology of interaction between teachers of a preschool organization and parents of pupils. Some approaches to the problem of organizing interaction between the family and the kindergarten are analyzed as a scientific field that requires a serious revision of traditional approaches as outdated, not meeting the actual needs of the time. It is emphasized that interaction is a prerequisite for the successful development and socialization of children. Two traditionally established educational institutions: social and family education - today especially need to combine their efforts in order to create a single educational space. Purpose of the research: to study the pedagogical conditions of teaching teachers the technology of interactive interaction with the parents of pupils. Research methods: theoretical analysis of scientific research, conversation, survey, pedagogical experiment to test the developed system of methodological measures aimed at teaching teachers the technology of interactive interaction with families of pupils (business games, workshops, trainings, discussions). According to the results achieved, the authors came to the conclusion about the effectiveness of the developed system of methodological measures, which makes it possible to successfully implement the training of teachers of preschool educational organizations in the technology of interactive interaction with the families of pupils. The authors focus on the need to use the technology of interactive interaction as the most productive way of communication, increasing the interest and activity of parents in discussing issues of education and training.

Published: April 2021

The effective use of financial resources that ensure the work of any organization largely determines the results of economic activities. It follows from this that the key point in the functioning of the company is taking care of finances. In modern market conditions, organizations have acquired the independence of running and managing the economy, bear full economic responsibility for their decisions, and also manage the results of labor and resources. In this case, the financial success and well-being of the organization depends entirely on the effectiveness of the analysis of the financial condition. For a reliable analysis of bankruptcy, it is necessary to choose an assessment methodology that is suitable for the activities of the organization. This is the main problem of analysis: a large number of different ways create difficulties for diagnosing enterprise problems. When using standard approaches, the number of exceptions in the interpretation of the analysis results increases, and this causes an increase in the set of methods for analyzing the financial condition of an enterprise. With all this, a large number of different coefficients does not always improve the quality of the analysis, but often complicates its interpretation.

Background: Lack of postoperative acute pain management is associated with increased morbidity, longer recovery time, more opioid use and subsequently increased health care costs. There is increasing evidence that Virtual Reality (VR) is effective in the reduction of acute pain. Alternative methods to reduce postoperative pain and multimodal analgesia are necessary for acute postoperative pain management and to reduce opioid use and their adverse effects. The aim of this study is to explore the effect of VR on pain in the postoperative period after elective gynecological surgery. Methods and Design: The study concerns a non-blinded, single center, randomized controlled trial. Eligible women fulfilling the inclusion criteria and receive elective gynecological surgery in the Zuyderland Medical Center will be randomized for participation. The study population will be randomly divided into the intervention group (VR-group) or the standard care- group. The intervention group can choose for an immersive guided relaxation VR experience or an interactive VR experience during the pre- and postoperative period additional to the usual standard care. The participants randomized to the standard caregroup will receive only the usual standard care pre-and postoperative. The primary outcome is postoperative pain measured on a Numeric Rating Scale (NRS). A total of 30 patients have to be included in each group. This means that a total of 60 women will have to be included in this study. Secondary outcomes are; evaluating pre-and postoperative anxiety, pain catastrophizing, analgesic use, length of hospital stay between both groups and to explore tolerability, feasibility and satisfaction of VR use. Discussion: This study will provide insight as to whether in women who receive gynecological surgery, VR is an effective method to reduce postoperative pain and subsequently opioid use.

A series of novel metal organic frameworks with lanthanide double-layer-based inorganic subnetworks (KGF-3) was synthesized assisted by machine learning. Pure KGF-3 was difficult to isolate in the initial screening experiments. The synthetic conditions were successfully optimized by extracting the dominant factors for KGF-3 synthesis using two machine-learning techniques. Cluster analysis was used to classify the obtained PXRD patterns of the products and to decide automatically whether the experiments were successful or had failed. Decision tree analysis was used to visualize the experimental results, with the factors that mainly affected the synthetic reproducibility being extracted. The water adsorption isotherm revealed that KGF-3 possesses unique hydrophilic pores, and impedance measurements demonstrated good proton conductivities (σ = 5.2 × 10−4 S cm−1 for KGF-3(Y)) at a high temperature (363 K) and high relative humidity (95%).
Two, three, or not to be? Elucidating Multiple Bonding in d6 Pseudotetrahedral Oxo and Imide Complexes
Authors: Gardner Joel , Schneider Joseph , Anderson John
Published: April 2021

Late transition metal oxo and imide complexes play an important role in the catalytic functionalization and activation of small molecules. An emerging theme in this area over the past few decades has been the use of lower-coordination numbers, and pseudo-tetrahedral geometries in particular, to stabilize what would otherwise be highly reactive species. However, the bonding structure in d6 oxo and imide complexes in this geometry is ambiguous. These species are typically depicted with a triple bond, however recent experimental evidence suggests significant empirical differences between these complexes and other triply bonded complexes with lower d-counts. Here we use a suite of computational orbital localization methods and electron density analyses to probe the bonding structure of isoelectronic d6 Co(III) oxo and imide complexes. These analyses suggest that a triple bond description is inaccurate due to a dramatically weakened σ interaction. While the exact bond order in these cases is necessarily dependent on the model used, several metrics suggest that the strength of the metal–O/N bond is most similar to other formally doubly bonded complexes.
A New Imaginary Term in the 2nd Order Nonlinear Susceptibility from Charged Interfaces

Published: April 2021

Non-resonant second harmonic generation phase and amplitude measurements obtained from the silica:water interface at varying pH and 0.5 M ionic strength point to the existence of a nonlinear susceptibility term, which we call , that is associated with a 90° phase shift. Including this contribution in a model for the total effective second-order nonlinear susceptibility produces reasonable point estimates for interfacial potentials and second-order nonlinear susceptibilities when . A model without this term and containing only traditional and terms cannot recapitulate the experimental data. The new model also provides a demonstrated utility for distinguishing apparent differences in the second-order nonlinear susceptibility when the electrolyte is NaCl vs MgSO4, pointing to the possibility of using HD-SHG to investigate ion-specificity in interfacial processes.

Published: April 2021

This study was aimed to isolate the endophytic bacteria and fungi from the fruit and root of Musa Paradisiaca, commonly called as Nendran banana cultivar in the southern Indian state of Kerala. Endophytes are microbes living in plant tissue without harming the plants rather existing as potential beneficial organisms. Musa paradisiaca is a less explored variety of banana cultivar which possess anti-disease potential apart from nutritional quality. The total number of twelve root and fruit associated endophytes were isolated. The fruit associated endophytes were seven with four bacterial isolates and three fungal isolates. The number of root-associated endophytes were five with three bacterial isolates and two fungal isolates. The morphological characterisation of both root and fruit endophytes were performed by Gram staining for bacteria and lacto-phenol cotton blue staining for fungi. The bacterial colony examination of the fruit associated culture revealed a specific pink strain with an inhibitory zone proving antibacterial activity which was further investigated through agar well diffusion test.  The strain exhibited potential antibacterial activity against five human clinical pathogens. A significant zone of inhibition was observed against Bacillus subtilis  (22 mm), Escherichia coli (21 mm), Klebsiella pneumonia  and Pseudomonas aeruginosa (18 mm) which confirmed the potential antibacterial property of the fruit endophytic strain.

Children living in rural areas are prone to nutritional deficiencies. Low-income levels impact people’s purchasing power so that the intake of most nutrients comes from plant-based foods and consumes less animal food. Nutritional intake greatly affects the development of children’s cognitive function. Brain-derived neurotrophic factor (BDNF) is a group of neurotrophins that contribute greatly to the learning process and memory. This study aims to analyze the relationship between levels of BDNF with the level of intelligence in elementary school children in rural areas of Seluma Regency. This was a cross-sectional study involving 70 elementary school children aged 9-12 years were taken by multi-stage random sampling, who came from 5 districts of Seluma Regency. Blood was collected for measurement of BDNF levels, and stool samples were examined to detect intestinal parasites. The data on respondent characteristics were derived from questionnaires.  Data analysis were done by using the chi-square test. The results of BDNF measurements found 31 children (44.3%) had BDNF levels below the average (<3342.95ng / mL). The results of measuring intelligence level found that 54 children (77.1%) had a level of intelligence below the average. Chi-Square test results obtained p = 0.012 with a PR value of 7.538. There was a significant  association between the BDNF level and intelligence level in elementary school students in the rural area. Elementary school children in rural areas with BDNF levels below the average risk of 7.538 times have below-average intelligence levels.
Silver i-motifs and their antibacterial activity
Authors:   , Bratt Jessica
Published: April 2021

The spread of antibiotic resistance and the emergence of multi-drug resistant bacteria is a major threat to public health. This study investigated a unique cytosine rich DNA structure, the i-Motif to deliver soluble Ag+ as a novel antimicrobial agent (AgiMs). AgiMs were evaluated in vitro against P. aeruginosa and A. baumannii strains. AgiMs displayed significant antibacterial activity against both P. aeruginosa and A. baumannii (median MIC: 0.875 µM and 0.75 µM, respectively) by rapid, bactericidal and concentration-dependent effect. Low concentrations of AgiMs showed efficacy against PAO1 20-h biofilms, resulting in 57% reduction in biomass (5 x MIC). A single dose of AgiMs extended survival of G. Mellonella larvae, with the therapeutic benefit paralleled in the reduction of internal bacterial load. Synergistic interactions were observed with the combination of AgiMs and tobramycin, a common antibiotic used to treat P. aeruginosa infections; indicating the potential for AgiMs to reinstate the potency of current antibiotics. This silver-based agent might be an alternative to the failing antibiotic regimes for MDR resistant infections. Further in vitro and in vivo studies are warranted to confirm the therapeutic potential.
Numerical modelling of dynamic resistance in high-temperature superconducting coated-conductor wires
Authors: Ainslie MD , Bumby Christopher , Jiang Zhenan , Toyomoto R , Amemiya N
Published: April 2021

The use of superconducting wire within AC power systems is complicated by the dissipative interactions that occur when a superconductor is exposed to an alternating current and/or magnetic field, giving rise to a superconducting AC loss caused by the motion of vortices within the superconducting material. When a superconductor is exposed to an alternating field whilst carrying a constant DC transport current, a DC electrical resistance can be observed, commonly referred to as ‘dynamic resistance.’ Dynamic resistance is relevant to many potential hightemperature superconducting (HTS) applications and has been identified as critical to understanding the operating mechanism of HTS flux pump devices. In this paper, a 2D numerical model based on the finite-element method and implementing the H-formulation is used to calculate the dynamic resistance and total AC loss in a coated-conductor HTS wire carrying an arbitrary DC transport current and exposed to background AC magnetic fields up to 100 mT. The measured angular dependence of the superconducting properties of the wire are used as input data, and the model is validated using experimental data for magnetic fields perpendicular to the plane of the wire, as well as at angles of 30° and 60° to this axis. The model is used to obtain insights into the characteristics of such dynamic resistance, including its relationship with the applied current and field, the wire’s superconducting properties, the threshold field above which dynamic resistance is generated and the flux-flow resistance that arises when the total driven transport current exceeds the field-dependent critical current, Ic(B), of the wire. It is shown that the dynamic resistance can be mostly determined by the perpendicular field component with subtle differences determined by the angular dependence of the superconducting properties of the wire. The dynamic resistance in parallel fields is essentially negligible until Jc is exceeded and flux-flow resistance occurs.
Investigating changes in land cover in high-density settlement areas by protected scenario
Authors: YAKUP Ahmet Emir , AYAZLI İsmail Ercüment
Published: April 2021

Uncontrolled urban growth is one of the most prominent problems in modern urbanism and planning. Rapid urbanization and population growth cause changes in land cover. In addition, determining the effects of these changes is essential in terms of sustainable urban management policies. Urban growth is a complex, dynamic structure that initiates changes in land cover. For this reason, simulation models are used extensively in planning studies. In this study, land cover simulation of the Sancaktepe district in Istanbul was carried out with the SLEUTH model based on cellular automata (CA). The study aims to identify the damage caused by uncontrolled urbanization. In this context, a scenario was created based on the assumption that forests will be protected based on the changes in land cover that occurred between 1961-2014. The data used in the model were generated from cadastral maps on a parcel basis. For this purpose, four-period data sets (1961-1992-2001-2014) were prepared between 1961-2014. According to the simulation results, 82% of agricultural land, 2% of forest land and 84% of open land will probably be converted into residential use. According to the results, it has been determined that almost all of the open and agricultural land in the towns of Pasakoy and Samandira in the district of Sancaktepe have been converted into residential areas. According to the prediction that the changes in current land cover will continue, no change is expected in forests, while it has been determined that the potential to transform agricultural land and open land into settlement areas is quite high.

In view of the technical development requirements of digital agriculture and the requirement of operation parameter regulation in the operation process of grain harvester. An on-board grain mass flow monitoring system based on pressure sensor was developed. The mathematical model of grain mass and grain flow pressure was established, which realized the real-time measurement, display, and storage of grain dry/wet quality information during the operation of grain harvester. An indoor bench test was carried out with the independently developed grain flow monitoring test bench. The results showed that the output error of the grain mass flow monitoring system was less than 4.25% under the conditions of indoor bench test, which meets the accuracy requirements of grain flow monitoring and provides the decision basis for variable seeding and variable fertilization.
Prediction of COVID-19 Confirmed Cases after Vaccination: Based on Statistical and Deep Learning Models
Authors: Kim Meejoung
Published: April 2021

In this paper, we analyze and predict the number of daily confirmed cases of coronavirus (COVID-19) based on two statistical models and a deep learning (DL) model; the autoregressive integrated moving average (ARIMA), the generalized autoregressive conditional heteroscedasticity (GARCH), and the stacked long short-term memory deep neural network (LSTM DNN). We find the orders of the statistical models by the autocorrelation function and the partial autocorrelation function, and the hyperparameters of the DL model, such as the numbers of LSTM cells and blocks of a cell, by the exhaustive search. Ten datasets are used in the experiment; nine countries and the world datasets, from Dec. 31, 2019, to Feb. 22, 2021, provided by the WHO. We investigate the effects of data size and vaccination on performance. Numerical results show that performance depends on the used data's dates and vaccination. It also shows that the prediction by the LSTM DNN is better than those of the two statistical models. Based on the experimental results, the percentage improvements of LSTM DNN are up to 88.54% (86.63%) and 90.15% (87.74%) compared to ARIMA and GARCH, respectively, in mean absolute error (root mean squared error). While the performances of ARIMA and GARCH are varying according to the datasets. The obtained results may provide a criterion for the performance ranges and prediction accuracy of the COVID-19 daily confirmed cases.Doi: 10.28991/SciMedJ-2021-0302-7 Full Text: PDF

Material and Methods: We performed a registry of patients with laboratory-confirmed SARS-CoV-2 infection who developed acute telogen effluvium and actively sought medical care at the Hair Unit of Dermatology Center of CUF Descobertas Hospital, from March 2020 to October 2020. Patient demographics, the month of SARS-CoV-2 infection diagnosis, COVID-19 associated symptoms, latency of telogen effluvium, duration of hair loss, and associated scalp symptoms were recorded.

Results: Twenty-seven patients recently diagnosed with SARS-CoV-2 infection presented with acute telogen effluvium. Of them, 5 (18.5%) patients mentioned trichodynia. The median time of latency of increased hair loss since SARS-CoV-2 infection diagnosis was 10 weeks. In a third of cases (n=9, 33.3%), hair loss occurred early (with a latency period of 3 weeks or less). The resolution of telogen effluvium was documented in 16 (59%) cases with a median duration of hair loss of 24.5 days. The most common symptoms of COVID-19 were fever (n=17, 63%), ageusia (n=8, 30%), cough (n=6, 22%), myalgia (n=5, 18.5%), anosmia (n=4, 15%), and thoracalgia (n=3, 11%). Four patients (15%) with SARS- -CoV-2 infection were asymptomatic for COVID-19.

Discussion: Acute telogen effluvium corresponds to a delayed consequence of an abnormal shift in the hair cycle from anagen to telogen, which is responsible for premature hair shedding, occurring approximately two to three months after a triggering event. Viral illnesses and febrile states are known causes. Regarding SARS-CoV-2 infection, we hypothesize that viral cytopathic effects and inflammatory or immune responses may affect hair follicles and explain hair loss and trichodynia.

Conclusion: Our case series presents the first comprehensive collection of patients with acute telogen effluvium following SARS-CoV-2 infection. Interestingly, in a third of our cases, telogen effluvium developed within the first 3 weeks of SARS-CoV-2 infection. Based on these data, we propose that this finding should be considered in COVID-19, especially at the convalescent phase.

Published: April 2021

The reconstruction of nasal skin defects is a challenge even for an experienced dermatological surgeon. When the defect is too large or complex to be corrected with simpler flaps, interpolated flaps are a good option, but they usually require two surgeries. Tunneled interpolated flaps were developed to allow the reconstruction of complex defects in only one surgical procedure. In nasal reconstruction, the main tunneled flaps are the paramedian forehead and the melolabial flaps. This review will focus on these two flaps: description of the technique, applications, advantages and disadvantages.

Published: April 2021

Cholinergic urticaria is a relatively common condition defined by itching, redness and whealing induced by exercise and passive warming. In turn, acquired idiopathic generalized anhidrosis is a rare disorder of unknown pathogenesis, characterized by an impairment in total body sweating despite exposure to heat or exercise. We report two cases of this extremely rare association of cholinergic urticaria and acquired generalized hypohidrosis, and briefly review current knowledge with regard to classification, ethiopathogenesis and therapeutic options.

Ризики та процедури впровадження в громадах системи управління якістю фізкультурно-спортивних послуг
Authors: Dorofieieva Tetiana
Published: April 2021

Актуальність. Проблема якості фізкультурно-спортивних послуг (ФСП) усе ще залишається поза увагою науковців, хоча напряму впливає на поширення послуг й ефект від їх споживання різними категоріями населення країни. Причому як населення міст, у частині з яких вже створено прийнятні умови для здійснення цих послуг, так і населення сіл. Мета дослідження – розкрити ризики та особливості впровадження системи управління якістю (СУЯ) фізкультурно-спортивних послуг. Методи дослідження. Використано методи теоре- тичного дослідження, як-от: вивчення літератури, абстрагування, аналіз і синтез, індукція й дедукція, ідеалі- зація та узагальнення, а також SWOT-аналіз. Результати дослідження та ключові висновки. Європейський досвід засвідчує: ефективність управління та якість послуг, що надаються населенню, у т. ч. фізкультурно- спортивних, можна забезпечити шляхом упровадження систем управління якістю (СУЯ). Тож умовою є ефективна діяльність відповідних організацій на основі міжнародних стандартів ISO серії 9000. Упровадження органом публічного управління вимог ISO 9001 сприяє позитивним змінам, які відчутні як для фахівців, котрі надають послуги, так і для споживачів цих послуг. Проведений SWOT-аналіз упровадження СУЯ у сфері фізичної культури й спорту в сільській місцевості, а саме в об’єднаних територіальних громадах дав змогу узагальнити таке. Чинники, які несуть ризики та перешкоди у впровадженні СУЯ щодо ФСП, можна об’єднати в такі групи: кадри, фінанси, матеріально-спортивна база, організаційна діяльність, фізкультурно-спортивний актив, населення громад і стандарти надання ФСП. Розкрито особливості розробки й процедури впровадження системи управління якістю фізкультурно-спортивних послуг органами публічної влади на основі стандартів. Доведено, що подані та обґрунтовані загальні вимоги й застереження мають бути взяті до уваги та застосовані в процесі безпосередньої підготовки системи стандартів управління фізичною культурою й спортом в умовах об’єднаних територіальних громад.

Актуальність. В усьому світі відзначається підвищена цікавленість до проблеми розумової відсталості в різних аспектах. Роль фізичної терапії розумово відсталих дітей полягає в корекції рухової сфери, у підвищенні рівня здоров’я й фізичної підготовленості, у позитивному впливі на психоемоційний стан. Мета дослідження – проаналізувати вплив засобів фізичної терапії на морфофункціональний стан та дрібну моторику хлопчиків 7– 8 років із легкою формою розумової відсталості. Матеріал і методи дослідження. У дослідженні, за пого- дженням батьків, узяли участь вісім хлопчиків віком 7–8 років із діагнозом за МКХ-10 – дебільність, F70 – легка розумова відсталість. Під час дослідження використовувались теоретичні методи дослідження, клінічний огляд, анкетування, опитування, антропометричні методи, функціональні методи, діагностика рухових функцій. Результати дослідження. За час експерименту, який тривав вісім місяців, показники фізичного розвитку й функціонального стану хлопчиків 7–8 років зазнали позитивних змін. Порівняльний аналіз показників розвитку дрібної моторики хлопчиків після експерименту показав значне покращення результатів тестування. Так, під час виконання тесту «Скласти мозаїку» різниця в показниках до й після проведення експерименту становила 2 бали, при <0,001; «Розкладання» та «Застібування ґудзиків» поліпшилося на 1,5 бали при p<0,001; «Шнуру- вання» і «Знайти квасолину» на 1,75 бала, при p<0,001; «Лови кульку» – на 1,25 бала при p=0,001; «Пересипання» – на 1 бал, при p=0,008; «Конструювання з паличок» – на 1,88 бала, при p<0,001. Висновки. Запропонована програма фізичної терапії позитивно вплинула на фізичний розвиток, стан серцево-судинної, дихальної систем і розвиток дрібної моторики хлопчиків 7–8 років із розумовою відсталістю легкої форми, що вказує на можливість їх розвитку при своєчасній спеціально спрямованій корекції.

Behçet Hastalığı ile İnterlökin-4 gen (VNTR) Polimorfizmi Arasındaki İlişkinin Araştırılması
Authors: KOCAAĞA Ayça , ÇAKMAK GENÇ Güneş , KARAKAŞ ÇELİK Sevim , HAZİNEDAR Emel , DURSUN Ahmet
Published: April 2021

Amaç: Behçet hastalığı (BH); mukokutanöz bulguların ön planda olduğu deri, göz, eklemler,

gastrointestinal ve merkezi sinir sisteminin çeşitli inflamatuar lezyonları ile karakterize sistemik

bir vaskülittir. Sitokinlerin BH patogenezinde önemli rolleri olduğu ve sitokin üretiminin genetik

polimorfizmlerden etkilenebileceği bilindiğinden bu çalışmada IL-4gen (değişken sayılı ardışık tekrarlar-

VNTR) polimorfizmi ile BH arasındaki ilişkinin araştırılması amaçlanmıştır.

Gereç ve Yöntemler: Bu çalışmaya ‘Uluslararası Behçet Hastalığı Çalışma Grubu’ tanı kriterlerine

göre tanı almış 74 Behçet hastası ve 100 sağlıklı kontrol dahil edilmiştir. IL-4 geni VNTR (rs79071878)

polimorfizmi spesifik primerler kullanılarak PZR-RFLP (polimeraz zincir reaksiyonu sınırlama fragman

uzunluğu polimorfizmi) yöntemi ile genotiplenmiştir. Behçet hastaları ve kontrol grupları IL-4 gen VNTR

polimorfizmi açısından genotip ve alel dağılımlarına göre analiz edilmiştir. Ayrıca hastalar bazı klinik

bulgularına göre genotip ve alel dağılımlarına göre karşılaştırılmıştır.

Bulgular: IL-4 geni VNTR (rs79071878) polimorfizmi genotip ve alel dağılımları açısından Behçet hastaları

ve sağlıklı kontroller arasında istatistiksel olarak anlamlı bir fark bulunamamıştır(sırasıyla p=0.332

ve p=0.445). Hastalar bazı klinik özelliklerine göre gruplandırıldığında daIL-4 geni VNTR polimorfizmi

açısından gruplar arasında istatistiksel olarak anlamlı bir fark gözlenmemiştir. Gastrointestinal sistem

(GİS) tutulumu olan hastalarda P2P2 genotip frekansının GİS tutulumu olmayan hastalara göre daha

yüksek olduğu ancak bu farkın istatistiksel açıdan anlamlı olmadığı tespit edilmiştir (%90,0 ve %68,8;

p=0.052).

Sonuç: Bulgularımız IL-4 geni VNTR polimorfizminin BH gelişimi ve klinik bulguları ile ilişkili olmadığını

göstermiştir. Behçet hastalığı ve IL-4 geni ile ilgili sınırlı araştırmalar olması nedeniyle bu çalışma

literatüre önemli bir katkı sağlayacaktır.
