Published: August 2021

В данной статье решается задача формирования предложения продавца на электронно-торговой площадке, максимально соответствующего спросу покупателей. Рассматривается электронная торговая площадка с технологией маркетплейс, где продавцы и покупатели сообщают информацию о своих предложениях и спросе соответственно. Лингвистические переменные помогают составить качественное описание задачи. Спрос, предложение и функционально-стоимостные ограничения продавца задаются векторами параметров, заданных именно в форме таких переменных. Выбор вариантов предложения осуществляется на основе агрегирования нечетко заданных желаний и возможностей по каждой лингвистической переменной. В данной статье в качестве критерия для формирования предложения рассматривается компромисс между стремлением к максимальному соответствию обобщенному спросу покупателей и к максимальному соответствию функционально-стоимостным ограничениям продавца. В качестве оператора агрегирования используется дискретный интеграл Шоке с нечеткой мерой. Применение интеграла Шоке позволяет найти вероятность совершения сделки между продавцом и покупателями. Также используется понятие нечеткой меры, которое позволяет учитывать взаимодействие характеристических критериев товара. Вычисление плотностей нечеткой меры осуществляется с помощью экспертных методов. Проведена численная апробация формирования предложения продавца на конкретном примере. Для товара с конкретными значениями характеристических параметров вычисляется вероятность совершения сделки между продавцом и покупателями. Полученные результаты могут использоваться для автоматизации сервисов формирования предложения продавца на электронно-торговых площадках. Таким образом, продавец формирует свое предложение для достижения максимальной вероятности сделки.

Исследование решения задачи параметрической идентификации моделей распределенных динамических процессов
Authors: Матвеев Михаил Григорьевич , Сирота Екатерина Александровна
Published: August 2021

Идентификация параметров распределенных динамических систем является важной задачей технических, экономических и социальных приложений. При моделировании объектов таких приложений обычно используют уравнения многомерной авторегрессии с регрессорами, расположенными в смежных узлах пространственных координат. Очевидно, что в этом случае между регрессорами обычно существует значимая корреляционная зависимость. Возникает эффект квазимультиколлинеарности, следствием которого является завышенное значение стандартной ошибки оценок параметров авторегрессии, а также смещение получаемых оценок параметров. Среди различных методов повышения качества статистических оценок много таких, которые снижают стандартную ошибку и повышают смещение и, наоборот, среди них метод инструментальной переменной, ридж-регрессия и другие. Таким образом, наличие двух составляющих ошибки порождает необходимость поиска компромисса «смещения и разброса» хорошо известного в машинном обучении. Объектом нашего исследования являются уравнения множественной авторегрессии, полученные на основании аппроксимации однородных уравнений в частных производных с постоянными параметрами разностными уравнения со свойством консервативности. Разностная схема называется консервативной, если она сохраняет на сетке те же законы сохранения, что и в исходной дифференциальной задаче. В рамках данной работы проведен сравнительный анализ решения задачи параметрической идентификации в случае применения к ней обычного метода наименьших квадратов (МНК), ридж-регрессии и двух авторских методов понижения размерности. Сравнительный анализ применения исследуемых методов идентификации к оценке параметров показал существенную зависимость качества оценки от интенсивности помех наблюдения. При малых помехах все рассматриваемые методы успешно справляются с задачей идентификации. При увеличении интенсивности помех удовлетворительную работоспособность демонстрирует только авторский метод понижения размерности, основанный на учете свойства консервативности разностной схемы.

Published: August 2021

The objective of the study was to examine the level of strength fitness indicators of 10-year-old girls and experimentally test the effectiveness of the impact of play techniques with elements of martial arts on the dynamics of strength development.

Materials and methods. The study participants were 20 10-year-old girls who do Kyokushin Karate. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The following research methods were used to achieve the objective set: analysis of scientific and methodological literature, pedagogical testing, and methods of mathematical statistics for processing research results.

Results. There were the biggest changes in the results of the tests “Lying pull-ups” by 51.1% (p < 0.05), “Push-ups” by 34.1% (p <0.05), and “Bent arm hang” by 26.5% (p < 0.05). Somewhat smaller changes were observed in the tests “Right hand grip test” by 10.8% (p < 0.05), “Left hand grip test” by 10.5% (p <0.05), and “Sit-ups in 1 min” by 13.3% (p < 0.05). The lowest increase in the results was observed in the test “Triple jump on the right and left leg” by 6.6% (p < 0.05).

Conclusions. The level of the girls’ strength fitness at the initial stage of the pedagogical experiment conforms to age norms. Most of them are at the average – 40% and above average – 23.6% levels. The remainder of indicators was distributed between the high – 13.6%, below average – 14.3%, and low – 8.6% levels. A comprehensive control of the 10-year-old girls’ strength fitness after the formative experiment showed statistically significant changes in almost all indicators in the experimental group, which used play techniques with elements of martial arts in the following load mode: 5 games, 2 repetitions with rest intervals of 40 s (p < 0.001).

Published: August 2021

The article identifies diagnostic markers and performance-specific features of young people’s anticipation depending on their age and gender. The social and psychological analysis of their life strategies and anticipation orientations in the conditions of changes was carried out. The sample was differentiated according to the indicators of the leading anticipation constructs and predictors under life changes. The sociopsychological nature of young people’s social well-being was substantiated: the phenomenon of social well-being, its components, indicators, factors of formation were described; the empirical research project on young people’s social well-being was developed and the research was implemented; and correlations between social well-being and anticipation were determined; the referents determining young people’s social well-being were revealed. Mutual relations between an individual’s social well-being and anticipation are supported by patterns that depend on his/her age, gender, general anticipation capacity and individual characteristics (spatial, temporal, personal-situational). In addition, anticipation is developed actively stepby-step. In particular, in adolescence, the ability to anticipate is improved due to qualitative improvement of thinking, as an indirect and generalized reflection of reality; intensive development of those mental qualities that are specific to anticipation, such as: seeing of prospects, taking into account the probabilistic future, proving of made forecast. At the early adulthood, there is the mutual influence of the general anticipation ability and health, reflection during anticipation improves considerable. Anticipation at the middle adulthood is often associated with well-being, which is a sign of psychological health (emotional stability, low anxiety and impulsivity, etc.). In addition, there is a strong link between anticipation and positive well-being at the middle adulthood.
Gender differences were revealed for correlations determined between well-being and different anticipatory abilities. Significant correlations between well-being and different anticipatory abilities revealed for women were more numerous and stronger than that of men. The mutual relations among young people’s anticipatory abilities at different levels (personalsituational, spatial and chrono-rhythmic) and the the components of their well-being were determined.

Published: August 2021

BACKGROUND: Computer-aided design and three-dimensional printing have been used in various clinical and fundamental medicine fields, especially in surgery. For example, in the preoperative period, the correspondence of printed products to the anatomy can play an important role in evaluating pathological changes and correction methods. However, determining dimensional deviations of printed models involves ethical and technical difficulties associated with defining a reference and taking many measurements, respectively. Therefore, we propose to use a geometric object with known dimensions as a reference and estimate linear deviations using the Iterative Closest Point algorithm for each of the vertices of the prototyped polygonal mesh.
AIMS: To evaluate the geometric deviations associated with creation of bone-like physical objects from computed tomography data using computer-aided design and additive manufacturing.
MATERIALS AND METHODS: The source object was created using the FreeCAD application; Blender and Meshmixer software was used for polygon meshes correction and transformation. The 3D printing was carried out on an Ender-3 printer with copper-impregnated polylactide plastic BFCopper. Scanning was performed using a 128-slice tomograph Philips Ingenuity CT. A series of tomographic images were processed in 3DSlicer software to create virtual models by semiautomatic segmentation with threshold values of 500 HU, 0 HU, 500 HU, 750 HU, and manual segmentation. Reproduced and reference polygon meshes were compared using the Iterative Closest Point algorithm in CloudCompare software.
RESULTS: The volume of reproduced models exceeded the volume of respective reference models by 1%27%. The average point cloud linear deviation values of reproduced models from the reference ones were 0.030.41 mm. A significant correlation between integral sums of linear deviations and changes in the volume of reproduced models was shown using Spearman's rank correlation coefficient ( = 0.83; temp = 5.27, p=0.05).
CONCLUSION: The geometry of the reproduced object changes inevitably, while the linear deviations depend more on the chosen segmentation method than on the overall size of the model or its structures. The manual segmentation method can lead to greater linear deviations, though it saves all the necessary anatomical structures.
A Protective dsRNA is Crucial for Optimum RNAi Gene Silencing in Chilo partellus
Authors: Adeyinka Olawale Samuel
Published: August 2021

RNAi technology is currently employed as an alternate control measure for agricultural pests. However, the variability of RNAi efficiency in insect pests limits the extensive usage of this technology and demands identifying the best target gene for effective RNAi. Four different bacterially-expressed dsRNA and purified dsRNAs coated on artificial diet were fed to the larvae. The transcripts expression was analyzed at 5 days and 15 days post-exposure to various dsRNAs. In the larvae fed on bacterially-expressed dsRNA, knockdown percentages were 80 and 57% knockdown in Acetylcholinesterase transcript, 40 and 60% gene knockdown in Arginine kinase, 74 and 73% knockdown in Chymotrypsin, and 80 and 20% reduction in V-ATPase transcript expression. Overall, the mRNA knockdown percentages in the targeted genes were more pronounced at 5 days of exposure to bacterially-expressed crude dsRNA than 15 days of exposure. However, most purified dsRNAs rarely induce any significant knockdown except dsARG, which reduced the arginine kinase transcript by 40%. Our findings suggest that for optimum RNAi in C. partellus, the dsRNA must be protected from direct access with nucleases. © 2021 Friends Science Publishers

Authors: Wu Zhi Hua
Published: August 2021

This study aimed to screen myxobacteria strains with strong activity against Phytophthora infestans and to study its secondary metabolites. Myxobacteria were isolatedfrom a soil sample using the rabbit feces as bait. A strain inhibitive to P. infestanswas identified by morphological observation and 16S rRNA sequence analysis. The fermentation parameters were optimized through a combination of univariate analysis and orthogonal optimization. The stability and antimicrobialactivities of the secondary metabolites were determined using the filter paper method, and the effects on the development of the potato late blight and its pathogen were determined using the in vitroleaf method. The myxobacteria B25-I-1 isolated from a soil sample showed strong activity against P. infestansand was identified as Myxococcus xanthus. The optimal fermentation conditions of M. xanthusB25-I-1 were as follows: inoculum size of 10%, shaking at 180 rmin-1, incubation temperature of 32°C, and incubation time of 8 days. The secondary metabolites were highly tolerant to high temperature, treatment with protease K, andultraviolet and natural lights. Besides P. infestans, the secondary metabolites also showed variant antagonistic effects againstEscherichia coli,Staphylococcus aureus,Bacillus subtilis,Saccharomyces cerevisiae,Fusarium oxysporum, Rhizoctonia solani, and Sclerotinia sclerotiorum. The results of the potato late blight control on potato leaves indicated that the secondary metabolites could significantly inhibit the infection of detached potato leaves caused by P. infestansand caused no damage to the leaves of different varieties of potatoes by themselves. This study provides basic data for the the development of a biopesticide against potato late blight.© 2021 Friends Science Publishers
Improved Cold Tolerance is Associated with Altered Cell Wall Composition in Pre-Planted Tobacco
Authors: Fang Ming
Published: August 2021

Tobacco seedlings produced by floating system are susceptible to cold injury. This problem can be solved by pre-planting technique. However, little is known about the mechanism underlying the improved cold tolerance in pre-planting tobacco. To investigate it, the cytological features of the leaf and root cells from floating and pre-planting tobacco were studied. Obvious cold injury and rupture of cell membrane system were observed in the cells from floating tobacco under cold stress conditions but very little in the cells from pre-planting tobacco. The cell wall in cells from pre-planting tobacco was thicker than in floating tobacco before cold stress. The cell wall was higher in cellulose and pectin contents in pre-planting tobacco than in floating tobacco before and after cold stress. These results suggest that pre-planting technique facilitates the accumulation of cell wall compositions-cellulose and pectin in pre-planting plants to prevent the cold injury, and possibly attenuates the negative effect of flooding stress on cell wall composition. © 2021 Friends Science Publishers
SIX6 Shows High Divergence in Fusarium oxysporum f. sp. cubense TR4
Authors: Farah Nadya
Published: August 2021

Secreted fungal effector proteins and their host targets are good examples to understand the mechanism of host-pathogen co-evolution with genes involved in the interaction undergoing positive selection. SIX genes (secreted in xylem) are obtained via horizontal transfer and can be found within the formae speciales of Fusarium oxysporum. SIX6 and SIX9 of F. oxysporum f. spp. cubense (Foc) are predicted to play a role as effectors. However, their involvement in the pathogenicity of Foc in banana plants has not been determined yet. In the susceptible banana cultivar, we found that the SIX6 and SIX9 genes of Foc TR4 were highly expressed in roots, but not in corms or leaves. The host, however, expressed the pathogenesis-related (PR) genes, PR-1 and PR-3, in corms earlier than in the roots. Phylogenetic analysis on SIX6 and SIX9 genes of F. oxysporum has revealed the separation of SIX6 and SIX9 of Foc from other formae speciales. This leads to detecting genes under positive selection using the ratio nonsynonymous to synonymous substitution rates (Ka/Ks). SIX6 of Foc showed an increase in diversity, but insufficient to drive positive selection. Conversely, SIX9 of Foc showed no divergence in the dN/dS ratio distribution, indicating purifying selection. © 2021 Friends Science Publishers
First Report on Molecular Diagnosis and Phylogenetic Analysis of Hepatozoon canis in Naturally Infected Domesticated and Stray Dogs from Jhang, Pakistan
Authors: Abbas Mazhar
Published: August 2021

Canine diseases, particularly caused by tick-borne hepatozoons are responsible for high morbidity and mortality and are the reason for attracting significant focus. The current study was aimed to survey the occurrence of H. canis in domesticated and stray dogs of Jhang city (Punjab) with its molecular identification. For this, blood samples from 300 dogs (n=200 domesticated; n=100 stray) were collected and assayed through PCR for the detection of H. canis supported by sequencing analysis. The results demonstrated, 15.66% (47/300) of samples positive for H. canis. A significantly (P<0.05) higher occurrence of H. canis was observed in stray dogs (27%) than domesticated dogs (10%). Evaluation of the various risk factors showed that the age, sex, breed, dog category (domestic or stray), body coat, environmental settings (rural or urban) and ectoparasitic infestation were significantly (P < 0.05) associated with the occurrence of infection. The phylogenetic analysis of the PCR confirmed specimens revealed a very close homology of the detected strains with the ones diagnosed earlier in China and Malta. It was concluded that present moderate prevalence of H. canis among the dog populations in the area of Jhang may rise with stray dogs being most vulnerable hosts and potential source of vectors spread. © 2021 Friends Science Publishers
Effects of Combined or Along VFA, pH, Lipopolysaccharide and Histamine on the Rumen Epithelial Permeability of Dairy Goats In Vitro
Authors: Sun YY
Published: August 2021

This study investigated whether concurrent presence of lipopolysaccharide (LPS) and histamine (HIS) have the potential to increase permeability of the ruminal epithelium at physiological pH and acidotic ruminal pH. Nine 2.5-year-old female lactating Saanen dairy goats (42.79 ± 5.61 kg of BW; Mean ± SD) were used as a ruminant model. ruminal epithelium of goats were collected and mounted in Ussing chambers on their mucosal side in different gradient buffer solutions (pH 7.4, 5.5 and 5.2) containing LPS (0, 30 and 60 KEU·mL-1) or HIS (0, 0.5 and 10 ng·mL-1). The rumen epithelial electrophysiological indexes, such as short-circuit (Isc), tissue conductance (Gt) and the permeability of marker molecules of different sizes (horseradish peroxidase, HRP and fluorescein 5(6)-isothiocyanate, FITC) from the mucosal to the serosal side, were measured. Both Isc and Gt were increased, accompanied by enhanced flux of FITC, with a decrease of mucosal pH (P < 0.05). The addition of LPS at mucosal pH 5.2 significantly increased Isc, Gt and FITC flux rates and decreased potential difference (PD) (P < 0.05). Additionally, the concurrent presence of LPS and HIS at both physiological and acidotic ruminal pH also significantly increased the permeability of ruminal epithelium asevidenced by increasing Isc, Gt and FITC flux rates and decreasing PD. In summary, our results have shown that concurrent presence of LPS 60 KEU‧mL-1 and HIS 10 ng‧mL-1 at mucosal pH 5.5 can increase the permeability of ruminal epithelium. The combination of low pH and both high LPS and HIS may increase vulnerability to aggravated rumen epithelial barrier dysfunction. © 2021 Friends Science Publishers
Growth and Development of Soybean Plants with the Pat Gene under different Glufosinate Rates
Authors: Mundt Tamara Thaís
Published: August 2021

The pat gene confers tolerance to glufosinate in transgenic soybean plants; however, some aspects of the selectivity of this herbicide need to be better elucidated. This study aimed to evaluate the development of soybean plants with the pat gene under the application of different glufosinate rates. The experiment was conducted in a greenhouse and included seven different glufosinate rates of and two soybean cultivars (LL0291 and LL0767) with the pat gene, with four replications in a completely randomized design. Glufosinate was applied at the V4 stage (4 nodes on the main stem with fully developed leaves beginning with the unifoliolate nodes) of soybean, and the variables analyzed were: soybean injury, chlorophyll index, plant height, dry and fresh matter of shoots and roots, wet nodules, dry nodules, and total number of nodules. It was found that for both cultivars, the maximum recommended glufosinate rate of 700 g of active ingredient (ai) ha-1 was safe, rates above 1,250 g ai ha-1 may interfere with development, especially biomass accumulation, and, in general, cultivar LL0291 exhibited more injuries than cultivar LL0767. The glufosinate-tolerant soybean (with pat gene) is a great option for farmers, but care should be taken with respect to rates above the maximum recommended in the package insert, so that there is no damage to soybean. © 2021 Friends Science Publishers
Antidiabetic, Antibacterial and Antioxidant Potential of Bioactive Peptides Extracted from the Germinated Seeds of Poncirus trifoliata
Authors: Mehmood Tahir
Published: August 2021

The seeds proteins are converted into the peptides during the germination through peptidases. These bioactive peptides are fractionated through the enzymes. The bioactive peptides are reported with the number of therapeutic effects like antioxidant, antibacterial, antidiabetic, anti-cancerous and antihypertensive etc. Synthetic drugs have number of adverse effects along with the therapeutic effects, but natural sources are safer and free from this problem. In the present research, Poncirus trifoliata seedling peptides extracts were used to determine antibacterial, antioxidant and anti-diabetic activities. The peptides extract showed substantial growth of inhibition against pathogenic strains including Escherichia coli, Staphylococcus aureus and Bacillus subtilis having the superior effect as compared to amoxicillin antibiotic as a standard drug. The IC50 value of P. trifoliata seeds peptides extract was 32.91 μg mL-1 as compared with standard (IC50) value 25.52 μg mL-1 of ascorbic acid showed good potential as antioxidant activity. The extracted germinated seeds peptides showed considerable antidiabetic activity in controlling the blood glucose level of alloxan induced diabetic rabbits to compare with standard drugs like glibenclamide. Thus, this study confirmed the antibacterial, antioxidant and antidiabetic effects of P. trifoliata seeds peptides is significantly higher as compared to pure drugs. Therefore, further complete separation and detailed investigation study is needed to isolate target peptides and revealed mechanism of action of bioactive peptides and formulation as a drug to replace the synthetics drugs with safe one. © 2021 Friends Science Publishers
Morphological and Molecular-Biological Changes in the Coronary Arteries after Stenting
Authors: Todorov S. S. , Deribas V. J. , Kazmin A. S. , Todorov (jr.) S. S.
Published: August 2021

This review addresses morphological changes in coronary arteries following stenting, which result from damage to the vascular wall. These changes include 1) formation of a thrombus in the site of intimal injury; 2) inflammation; 3) proliferation and migration of smooth muscle cells; 4) formation of extracellular matrix. Each of these pathological processes has specific morpho-biological features. The review shows the role of von Willebrand factor in development of early thrombosis after intimal injury, which provokes activation of the inflammatory response followed by proliferation of smooth muscle cell that synthetize the extracellular matrix. These cellular and intercellular changes are based on overexpression of TGF-β1 protein, which facilitates modulation of various types of smooth muscle cells, including contractile and secretory ones. Issues of fine regulation of cellular and intercellular interactions by apoptosis, activation of mTOR signaling molecules, and microRNA are still understudied. Dynamic changes in drug-coated stents during development of neoatherosclerosis and late thrombosis remain not elucidated. Current reports show that initial mechanisms triggering pathological regenerative and hyperplastic processes that result in coronary restenosis in the area of implanted stents may form early (first hours or days) after stenting. Most studies were performed on experimental rather than on autopsy material, which does not allow fully unbiased interpretation of obtained data. Studying dynamics of morphological and molecular changes in coronary arteries after stenting, including on autopsy material, will allow one to express an opinion on the risk of postoperative thrombosis and restenosis.

Authors: Ozgeyik Mehmet , Ozgeyik Mufide Okay
Published: August 2021

Aim    Mortality prediction is very important for more effective treatment of patients with acute coronary syndrome. Hematological and lipid parameters have been used for this purpose, as this approach is non-invasive and cost effective. In this study, our aim was to evaluate which parameter predicts mortality most accurately.Material and Methods    Data of 554 patients with at least one total coronary artery occlusion were collected retrospectively. Receiver operating characteristic curves were used to determine the optimal cut-off points of Neu / HDL, Neu / Lym, Mono / HDL, Trig / HDL, HDL / LDL, Plt / Lym and Lym / HDL according to long-term cardiovascular survival. Median follow-up time was 520 days, and 30 patients died.Results    The mean age was 60.96±0.50 yrs. The area under the curve (AUC) for Neu / HDL was 0.830 (p<0.001, 95 % confidence interval [CI]: 0.753 to 0.908). The cut-off point was 0.269, with a sensitivity of 74.2 % and a specificity of 74.2 %. The AUC for Neu / Lym was 0.688 (p<0.001, 95 % CI: 0.586 to 0.790). The cut-off point was 5.322, with a sensitivity of 67.7 % and a specificity of 67.1 %. The Neu / HDL (hazard ratio, HR [confidence interval, CI]: 0.202 [0.075–0.545], p=0.002) and Neu / Lym (0.306 [0.120–0.777], p=0.013) were associated with increased risk of death according to multivariate Cox regression analysis.Conclusions    Neu / HDL offers a better long-term mortality prediction than Neu / Lym, Mono / HDL, Trig / HDL, HDL / LDL, Plt / Lym, or Lym / HDL after treatment of total coronary artery occlusion.

Published: August 2021

Background: Laparoscopic surgery is dominating in the field of hernia. The search for the ideal prosthetic biomaterial has been a longstanding issue with debate over simple versus composite biomaterial and lightweight versus heavyweight meshes. This study was done to evaluate the early outcome of lightweight mesh in laparoscopic totally extraperitoneal (TEP) repair.Methods: This prospective observational study was done for a period of 16 months. On the basis of selection criteria patient underwent laparoscopic TEP repair using light weight mesh, early outcomes were evaluated in terms of immediate postoperative pain (analysed via visual analog scale) and chronic groin pain (analysed by visual analogue scale and graded according to Cunningham), patients were also evaluated for operation time, intraoperative bleeding, seroma, stiffness or numbness around groin, or any other complications.Results: There was no intraoperative bleeding among any of the patients. Immediate post-operative pain assessed by visual analogue scale 20% scored one in the visual analogue scale in post-operative day 1. None of the patients were having any complications (like stiffness or numbness in groin or thigh and any other complication) during post-surgery follow up. Only one patient reported mild chronic groin pain at the end of 3 months after surgery.Conclusions: The short term results of laparoscopic TEP repair for inguinal hernia using light weight mesh are quite encouraging. We can conclude that light weigh mesh is fulfilling important role in successful hernia repair as it is associated with very less morbidity.
Two-Sided Market Power in Firm-to-Firm Trade
Authors: Alviarez Vanessa , Fioretti Michele , Kikkawa Ken , Morlacco Monica
Published: August 2021

Firms in global value chains (GVCs) are granular and exert bargaining power over the terms of trade. We show that these features are crucial to understanding the well-established variation in prices and pass-through across importers and exporters. We develop a novel theory of prices in GVCs, which tractably nests a wide range of bilateral concentration and bargaining power configurations. We test and evaluate the models predictions using a novel dataset merging transaction-level U.S. import data with balance sheet data for both U.S. importers and foreign exporters. Our pricing framework enhances traditional frameworks in the literature in accurately predicting price changes following a tariff shock. The results shed light on the role of firms in determining the tariff pass-through onto import prices.

Miłość i odpowiedzialność – wzajemne związki i zależności w perspektywie pedagogicznej
Authors: Maj Adam
Published: August 2021

Przedmiotem analizy jest relacja miłości i odpowiedzialności, ujęta w aspekcie aksjologii pedagogicznej. Fundamentem i źródłem obu wartości jest natura osoby ludzkiej. Miłość i odpowiedzialność, różniąc się między sobą, mają wspólne elementy w zakresie przedmiotu oddziaływania (Bóg, człowiek), treści (dobro), są podobne w dynamice rozwoju, stopniowalności i mają dialogiczny charakter. Zarazem występują w określonych zależnościach: ontycznych (miłość nie istnieje bez odpowiedzialności) i rozwojowych (dojrzałość miłości jest wprost proporcjonalna do rozwoju odpowiedzialności). Związki i zależności między obu wartościami implikują konieczność równoczesnego i umiejętnego wychowania do miłości i odpowiedzialności, które w dużym stopniu decydują o integralnym rozwoju wychowanka, jego człowieczeństwa i dojrzałości. Jest to istotne zadanie dla wychowawcy, którego działalność powinna cechować miłość i odpowiedzialność wychowawcza.

Rola przebaczenia według nauczycieli szkół średnich – czy uważają, że testowanie i ocena uczniów wiążą się z przebaczeniem?

Podczas gdy przebaczanie uznaje się za istotną wartość, ocena uczniów prowadzona z użyciem standardowych metod testowania jest rozwiązaniem bezlitosnym. Celem tego opracowania było zbadanie kwestii, jak nauczyciele postrzegają związek między testowaniem a przebaczeniem? Trzydziestu jeden nauczycieli szkół średnich poproszono o odpowiedzi na cztery pytania, po przedstawieniu im konkretnej definicji przebaczenia, sugerującej, że przebaczenie oznacza pozwolenie ludziom i uczniom na popełnianie błędów bez osądzania, dopóki nie zaczną robić tego, co należy. Odpowiedzi respondentów nagrano, przepisano i przeanalizowano. Po przeanalizowaniu zawartości uzyskano dziesięć kategorii. Niektóre z nich wskazują, że istnieje napięcie pomiędzy (a) uczuciami nauczycieli wobec uczniów i ich chęcią wspierania i pomagania im, a (b) formalnymi, odgórnymi wymaganiami systemu szkolnictwa. Badani nauczyciele wskazywali również na rolę istnienia granic wybaczania uczniom ich przewinień.

A capacidade das Instituições de Ensino Superior (IES) adotarem políticas e dinâmicas promotoras de interculturalidade para a inclusão dos estudantes apresenta-se como um desafio face aos relatos de vivências de exclusão académica dos participantes deste estudo. Foi objetivo deste estudo compreender a experiência vivida pelos participantes, na academia, como fenómeno de inclusão/exclusão. Relativamente aos métodos, trata-se de um estudo qualitativo, fenomenológico-interpretativo, com recurso à entrevista fenomenológica. Participaram trinta e um elementos da comunidade académica (estudantes, docentes e não docentes) de uma IES de Portugal, de abril a julho de 2019. A análise dos dados emergentes foi qualitativa e realizada com ajuda do software Nvivo12. Este estudo insere-se num projeto mais amplo intitulado “Práticas inclusivas no Ensino Superior: O desafio de construir comunidade”, autorizado pela Comissão de Ética da Instituição onde se realizou o estudo. Quanto aos Resultados, das categorias emergentes destacamos a Experiência e significado de inclusão, com destaque para a “Indiscriminação”, “Igualdade e equidade” e “Integração na comunidade”; as Barreiras à inclusão na instituição, com ênfase nas “Barreiras Arquitetónicas”, na “Desarticulação hierárquica institucional, “dificuldades linguísticas” e, ainda, a categoria Sentimentos vivenciados em experiências de exclusão, enfatizados pelos participantes, como a “desvalorização”, a “solidão” e a “tristeza”. Em conclusão, os participantes consideram que os principais desafios institucionais à inclusão e interculturalidade se centram no derrubar as barreiras arquitetónicas e linguísticas, de forma a que os edifícios tenham acessos adequados à mobilidade, que garantam a sua integração e minimizem sentimentos de desvalorização, solidão e tristeza.

Authors: Yusuf Muhammad , Mardan Mardan , Nahdhiyah Nahdhiyah , Marjumi Kamaluddin Nurdin
Published: August 2021

From a sociohistorical-anthropological perspective, the existence of an elite class with a class of people is known in the Qur’an. This research elaborates the verses of the Qur’an about elite society in social order. The existence of an elite society and its role in human civilization is the main concern in this study. Through the thematic interpretation method, typology and the role of elite society are explained. The terms prophet, apostle, malik, and al-mala’ refer to the elite.  Prophets and messengers are elite groups based on revelation, malik based on political power relations. The term al-mala’ is part of an elite society divided into three groups, namely al-mala’, which opposes the apostles, al-mala’, which does not oppose the da’wah of the apostles, and al-mala’ which has a hypocritical character. Da’wah and education carry the regeneration mission for the birth of new elites who are partners in the benefit. As for the opponents of da’wah and the elite who are hypocritical in character, they must be anticipated so as not to cause chaos, crisis, and crime.

Intelligence is often used as a benchmark to predict someone's success in the future. Therefore, intelligence is also often used as a reason for someone to label individuals who do not have the abilities that others want. Students of education as prospective educators in the future have a fairly central role in providing understanding about the intelligence that students have to parents, senior teachers, and students themselves. Before becoming an educator, education students are expected to have a good concept of intelligence so that the understanding given can be done precisely. This study aims to reveal the concepts of intelligence subjective to the students of prospective educators from the Javanese and Madurese tribes. The study used a qualitative research approach with a case study model that emphasized the exploration of a system that intertwined with each other. The results showed that education students who originated from Javanese and Madura tribe have a very diverse concept of intelligence. Despite the diverse concept of intelligence, the concept of the student intelligence of both tribes has a relation that complements each other. Students of both tribes also have the view that each individual has different intelligence. Therefore, most of the students from both tribes have been in line with Howard Gardner's multiple intelligences theory. The findings in this study are that interpersonal intelligence is considered to be the most prominent by the Madurese people, because the ability to connect and connect with others is very high.
The quest for a successful book-to-series adaptation in the times of SVOD — using the examples of “The Handmaid’s Tale and Alias Grace” by Margaret Atwood
Authors: Szydełko Joanna
Published: August 2021

A fascinating factor of so-called mass culture is the ability to adapt to society and its needs. The same pattern seems to be followed by the film industry, as it has been influenced by other branches of entertainment, television included. These are SVODs (Streaming Video on Demand platforms), which offer a growing number of screen adaptations of literary works. The following paper aims to analyse some criteria upon which book-to-series adaptations might be regarded as successful, using examples from The Handmaid’s Tale and Alias Grace.Produced respectively by Hulu and CBC, both based on books by the Canadian female writer Margaret Atwood, the analysed shows confirm that the audience is more inclined to watch (and read) an intertextual production that often reflects and comments on contemporary political and social reality.
From Frankfurt’s distraction of perception to the effect of decentration in the network
Authors: Lipiński Kamil
Published: August 2021

The article retraces the epistemological debates occurring in mass communication, from the problem of dispersed perception in the Frankfurt School to accelerated decentration in the theory of immaterial labour. The analysis covers, first of all, the theses of the Frankfurt School representatives concerning the disappearance of aura and distraction as a starting point for theoretical reflection on the problem of perception dispersion and, subsequently, the abolition of face-to-face communication in the decentralized internet. The purpose of following Hans Belting’s concept of “the presence of the absent places image” is to outline the tendency for acceleration and progressive decentration associated with the spatio-temporal compression and the flow of information posing a threat to material co-presence.

Published: August 2021

AbstractBackground: Puerperal post Sectio Caesarea was the period of physical and psychological drain, especially with HIV (Human Immunodeficiency Virus) as complication. In general, health workers still discriminate against HIV patients, as well as post-sectio mothers with HIV. This situation add to the psychological burden and increases the risk of depression during the puerperium. Midwife’s perception in caring for post-Section mothers with HIV is needed to produce attitudes and behaviours in supporting care. This study aims to describe the perception of midwives in providing care to post-sectio patients with HIV. Method: This study used a qualitative approach in two HIV referral hospitals in Surabaya with different class types. Participants in this study were determined by purposive sampling, consisting of 6 participants and 4 triangulation participants. Researcher conducted in-depth interview and closed observation with instruments such as recorders, observation sheets and the researchers themselves. Data processing and analysis is carried out by data reduction, data presentation and conclusions. Result: Participants in Hospital ‘A’ did not provide different services to post SC patients with HIV while still applying universal precautions. Participants in Hospital ‘B’ think that special treatment is needed by applying exaggerated universal precautions. Conclusion: Midwives keep trying to provide comprehensive care although there are differences in perception.
