The activity was conducted in Bekele-Girisa of Dugda district. The objectives were to demonstrate forage production from lablab under sown in maize and to evaluate the lablab-maize intercropping practices with farmers participation. Accordingly, Farmers' Research and Extension Groups (FREGs) with 18 members were established at Bekele Girisa kebele. Four trial farmers were selected from each FREGs for forage production based on the criteria including interest of the farmers in producing forage on their land, farmer having enough land for forage production and who have milking cows. BH-540 maize variety was intercropped with Lablab purpureus on plot a size of 32*32m2. Pure- stands of maize with similar plot size was also established for comparison. Lablab purpureus was intercropped in maize at two weeks period after maize planting. Farmers were used as replication with participatory approach. The results revealed that the total biomass (Stover + lablab) and maize grain yields were significantly different (P<0.05) among the practices at Dugda site. Even though statistically not significant (P>0.05) between the two practices, there was total biomass and maize grain yield increment in lablab under-sown in maize than pure stand of maize. Similarly, crude protein content of the maize Stover under sown with lablab was improved. Farmers were also very interested for forage production from lablab intercropping in maize as compared to sole maize production practice. Therefore, it is recommended to extend the forage production strategy such as lablab intercropping in maize to enhance the production of high biomass of forage with good quality.

Phosphorus (P) limitation in acidic tropical paddy soils is thought to be contributed by the affinity of iron oxides and hydroxides for phosphorus. However, the addition of labile carbon (C) compounds appears to be stimulated iron (Fe) reduction which can release occluded P through Fe cycling. The aim of this study was to investigate the phosphorous mobilization triggered by labile C coupled to iron (Fe) cycling during flooding anaerobic conditions in two P limited paddy soils. Two concentrations (low and high) of equal mixture of glucose and oxalate were added to soil microcosms and they were incubated for one month under flooded condition. During the 30-day experiment, replicate microcosms were destructively harvested for five times and measured total Fe, Fe II, available P and pH. It was found that labile C addition significantly increased total Fe and Fe II in soil solution at early incubation period although the changes were not significant in soil. Available P in soil was not increased and steady throughout the incubation period because the added labile C may not be enough to enhance the P solubilization or available P was dissolved in soil water which we did not measure in this experiment. High amount of labile C addition significantly decreased pH at the start of incubation. pH and available P are negatively correlated at day 7 which is compatible with decreased pH can increase available P. Our results suggest that reducing conditions coupled with labile carbon inputs can stimulate iron reduction and corresponding decreased pH which can triggered soil phosphorus mobilization in P limited paddy soils.

Banana propagation is dependent on propagation by tissue culture for industrial purposes. Due to lack of native endophytes in tissue culture plantlets, reintroduction of beneficial microorganisms to tissue culture plantlets become popular as a useful foundation for improving the level of establishment, increasing plant growth parameters, protecting the plantlets against pest and diseases and overall performance for field plantation. In the present study, rhizospheric and endophytic four bacterial species (Pseudomonas fluorescens, Bacillus putida, Bacillus pumilus, Bacillus amyloliquefaciens were isolated from different parts of healthy banana plants such as root, leaf and pseudostem. Banana tissue culture plantlets were cultured for root formation stage on MS medium and used as host for artificial inoculation. Then, bacterial inoculation was carried out with tissue culture plantlets both in vitro and ex vitro conditions. All banana plantlets used for this experiment were successfully acclimatized and survived in the greenhouse. The experiment consisted of three treatments: (1) bacterial inoculum with in vitro rooted plantlets for 2 weeks (2) bacterial inoculum with ex vitro (hardening) plantlets (3) control with sterilized distilled water. Among these treatments, in vitro inoculation affected significantly increased plant height, number of leaves and plant girth for all data collection times with the highest increment indices: (24.0, 7.0, and 7.3). Ex vitro inoculation showed the second highest increment indices: (22.0, 6.9 and 6.3) for plant height, number of leaves and plant girth, respectively. The lowest number of plant growth parameters were observed in control treatment for all four data collection time (19.0, 6.2, and 6.0). According to the results, application of mixtures of bacterial inoculum was effective for enhanced plant growth parameters of tissue culture banana plantlets under greenhouse condition. In addition, two weeks artificial inoculation during in vitro plantlets stage was found the most suitable method for application of microbes with tissue culture banana plantlets which can promote the microbial rhizosphere of banana prior to field plantation.

The study was conducted at Adami Tulu and Dugda districts of Oromia regional state, Ethiopia to determine the optimum level of seeding ratio and planting time of cowpea under maize for optimum forage biomass production and maize grain yield. Combinations of four levels of cowpea seeding ratios and four different cowpea planting dates were laid out in a randomized complete block design in factorial arrangement with three replications. The levels of seeding ratios were 100%, 75%, 50%, 25%, 0% (sole maize) for the two districts. The four planting dates for cowpea were simultaneously planting with maize, 10 days after maize planting (DAMP), 20 DAMP and 30 DAMP. The results indicated that increasing seeding ratio of cowpea from 25% to the highest level (100%) resulted in significantly increased cowpea forage biomass yield. Time of cowpea planting in maize also influenced the plant height and biomass yield of cowpea. The highest forage biomass yield was recorded from simultaneously planting of the two crops. On the other hand, seeding ratio of cowpea has significantly influenced the grain yield of maize. It was also indicated that the time of cowpea planting in maize have significantly affected the grain yield of maize with simultaneously planting resulting in the lowest grain yield. The total LER in most of the intercropping system was more than one showing that intercropping of forage legumes with maize is more advantageous than sole cropping of maize. The optimum forage legume biomass yield (1.78 t/ha) was obtained from the combination of seeding ratio of 75% with 10 DAMP without significantly (p>0.05) reducing the grain yield of maize. Hence this combination was recommended for production of cowpea forage and maize grain from intercropping of the two crops in the study areas. From these results, it can be concluded that additional forage can be produced by intercropping cowpea with maize at their appropriate seeding ratio and planting time with a little or no sacrifice in maize grain yield. Moreover, it is important to further demonstrate and promote the recommended maize-cowpea intercropping practices for the end users of the study areas and similar agro-ecologies.

„Zamknięty świat samobójstwa” – opowiadanie Fiodora Dostojewskiego Potulna
Authors:   University of Silesia, Michalska-Suchanek Mirosława
Published: May 2022

Apart from inherently associated with Fyodor Dostoyevsky ‘calculated’ egoistic, fatalistic and escapist suicides became one of the major themes in the writer’s work. The article attempts to analyze the image of the title character of the story titled Potulna, which combines the features of both types of suicidal death. The starting point for the analysis is the writer’s belief that the suicide is situated in the center of the “suicidogenic space”, understood as the whole of dynamically growing circumstances and conditions that, extended in time, determine the final solution. The true meaning of suicide is constituted through the process of cognition, and the final act itself is the tragic culmination of a tangle of interrelated factors.

Culture in Poland is the „ground” and all highest values are grounded in it, which was testified by a number of historical events. First of all, it is over one hundred and twenty years of geographical and political non-existence the Poles endured thanks to the highest culture, thanks to the works of the world’s greatest poets. Polish Poets are the greatest of the greatest and – therefore – completely untranslatable, which means – peculiar and national. They are extremly important for us, Poles, and urgently needed, indispensable. At the same time, Polish poetry has always bordered on self- -destruction. The Holy Trinity „God, Honor, Homeland” demanded from poetry to be a victim (Polish Romanticism). Let’s wish her another hundred years!
Environmental-Friendly and Non-Toxic TBSI as an Alternative for MOR Accelerator
Authors: Rethan Kiru , Sanjaya Amitha , Patabendige Chami N. K.
Published: May 2022

In the solid tyre rubber industry, most accelerators can produce n-nitrosamines as a by-product during the vulcanization process. As many n-nitrosamines are carcinogenic, they are highly regulated in final rubber articles and during manufacturing process.  2-(Morpholinothio benzothiazole (MOR) is the primary accelerator used in vulcanizing systems. It produces nitrogen toxic gases (nitrogen oxide and amine gas) which are carcinogenic. In this research MOR was successfully replaced with N-tert-butyl-2-benzothiazole sulfenimide (TBSI) accelerator which has no carcinogenic effect. The main objective of this research is to maintain its original properties while replacing MOR with TBSI accelerator.  This study was conducted and test samples were made of bonding rubber compound that is used to make the bonding layer of tyres which is the common part in all type of solid tyres. Physical-mechanical and bonding properties were analyzed for MOR and TBSI added bonding compound samples. Tensile, hardness, density and rheological using Oscillating die rheometer properties were also measured to maintain the quality of the tyre. The property change of bond layer can affects the other tyre layers. So, it can lead to failure of curing process or failure in performance of the tyre during the applications. The TBSI curing characteristics are closer to MOR sample. However other physical properties like hardness and density of TBSI samples were bit lower but they were in the required level as a bonding layer compound. Substitution of MOR by ‘safe TBSI’ compounds are still active as accelerators, but do not form carcinogenic gases.

Sargassum is a genus of brown seaweed rich in bioactive compounds such as fucoidan which has various health promoting properties including anti-cancer activity, anti-viral activity, and anti-inflammatory activity. This study examines the potential to develop herbal tea using Sargassum cristaefolium and Sargassum crassifolium Seaweeds were collected from the southern coastal area of Sri Lanka and identified using a morphological key. Each seaweed type was thoroughly cleaned, blanched, and dehydrated either by oven-drying (40 ℃ for 48 h) or freeze-drying technique and separately ground to a coarse powder, which resulted in four treatments as oven-dried S. cristaefolium and S. crassifolium, and freeze-dried S. cristaefolium and S. crassifolium. Dried Sargassum powders were analyzed separately for moisture content, total phenolics (Folin-ciocalteu method), total flavonoids (Aluminum chloride method), and radical scavenging activity (DPPH method), total carotenoids, and fucoidan content (spectrophotometric method). Freeze-dried Sargassum powder samples gave significantly higher total phenolic content (P<0.05) compared to oven-dried Sargassum powder. Total phenolics content of S. crassifolium and S. cristaefolium were 0.73± 0.12 and 1.27± 0.32 mg gallic acid equivalents/g dry weight, respectively. Total flavonoid contents were not significantly different among the S. cristaefolium and S. crassifolium seaweed powder considering oven drying and freeze-drying method. Freeze-dried Sargassum powders gave significantly higher radical scavenging activity (P<0.05) than oven-dried Sargassum powders. Radical Scavenging activities of freeze-dried S.crassifolium and S.cristaefolium powders were 34.6%± 1.87 and 46.83±8.30%, respectively. Oven-dried Sargassum powders gave significantly higher total carotenoid content (P0.05) than freeze-dried powders. Total carotenoid content of S.crassifolium was 1.88± 0.002 µg/g dry weight while it was 1.86± 0.089 µg/g dry weight for S.cristaefolium. Freeze-dried Sargassum powders gave higher fucoidan content than oven-dried powders however there were no significant differences in the fucoidan content considering the four treatments and their tea liquors. Fucoidan content of the freeze-dried S.crassifolium seaweed powder was 30.74± 6.36 mg/200 mL, while that of S.cristaefolium was 30.0± 4.09 mg/200 mL. A 5 g weighed tea bag was brewed in 200 mL distilled water for 20 min for the preparation of herbal tea. The highest overall acceptability was taken from the oven-dried S.cristaefolium tea from the sensory evaluation. Results revealed that Sargassum powders can be successfully used as herbal tea with functional properties.

Published: May 2022

Study Design: Retrospective case-control study.Purpose: To reduce unnecessary absolute bed rest (ABR), this study sought to determine the optimal aimed length of ABR in older patients getting conservative treatment for osteoporotic vertebral fractures (OVFs).Overview of Literature: OVFs are quite common in elderly patients. ABR is a vital part of conservative treatment for OVFs, although the length of ABR may increase patient. No recommendations regarding how long ABR should last.Methods: This study was conducted in 134 patients with OVFs initially treated conservatively. The patients were split into two groups: 3-day and 7-day ABR. From the time of injury to 1, 4, and 12 weeks after injury, compression rate (CR) and local kyphotic angle (LKA) were assessed and compared between the two groups. Any complications such as pneumonia, deep vein thrombosis, delirium, and urinary tract infection known to be related to ABR were examined based on the electronic medical record.Results: Forty-four patients underwent ABR for 3 days and 90 underwent ABR for 7 days. There was no significant difference in CR and LKA between the two groups at the time of injury versus 1, 4, and 12 weeks after injury. The patients were divided into two groups: those who received a 3-day ABR and those who received a 7-day ABR. CR and LKA were measured and compared between the two groups from the time of damage to 1, 4, and 12 weeks after injury. The ABR-related complication rate was 43.4% in the 7-day ABR group and 22.7% in 3-day ABR group (p=0.02). The duration of hospital stay was significantly shorter in the 3-day ABR group (12.8 days) than in the 7-day group (16 days) (p=0.01).Conclusions: Considering radiological outcomes, prognosis, complications, patient convenience, and economic impact, a 3-day ABR period is appropriate for the conservative treatment of OVFs.

Published: May 2022

Study Design: This cross-sectional study was conducted in a single hospital.Purpose: To clarify the relationship between lower limb pain intensity and dynamic lumbopelvic-hip alignment in patients with lumbar spinal canal stenosis (LSS), using a three-dimensional (3D) motion analysis system.Overview of Literature: Although it is well known that leg symptoms have a close relationship with posture in patients with LSS, the relationship under dynamic conditions, such as gait, remain unclear.Methods: Thirty patients with LSS scheduled for spine surgery participated in this study. Lower limb pain was assessed using the Visual Analog Scale (VAS), and the patients were divided into two groups based on the mean scores (patients with scores above and below the mean were classified as the high-VAS and low-VAS groups, respectively). The kinematics of the spine, pelvis, and hip joints during gait were then measured using a 3D motion analysis system. Student paired t -tests were used to compare the angles of the spine, pelvis, and hip during gait between the two groups.Results: Compared to those in the low-VAS group, the spine was significantly extended and bent toward the more painful lower limb side, and the pelvis was significantly anteriorly tilted among individuals in the high-VAS group.Conclusions: Patients with LSS experiencing severe pain in their lower limb tend to keep the spine in a more extended position, bend laterally toward the painful side, and have an anteriorly tilted pelvic posture. The dynamic spinal and pelvic alignment was closely related to the intensity of the lower limb pain.
Reciprocal Changes in the Whole-Body Following Realignment Surgery in Adult Spinal Deformity
Authors: Lee Jae-Koo , Hyun Seung-Jae , Kim Ki-Jeong
Published: May 2022

The idea of the global balance of spine stems from Jean Dubousset, who first introduced the concept of cone of economy. Through the compensatory mechanisms, the human body maintains an upright posture and horizontal gaze in the setting of the spinal malalignment. Compensation takes place not only in the mobile spine segments, but also in the pelvis and lower extremities. Patients with a malalignment exhibit compensatory changes in the cervical hyper-lordosis, posterior pelvic shift, knee/ankle flexion, hip extension, and the pelvic retroversion. The advent of whole-body stereo radiography has yielded an improved understanding of global changes among the patients. Deformity-induced compensatory changes in the sagittal alignment could be resolved reciprocally after the surgical correction of the malalignment. Thoracolumbar realignment surgery restores the pathologic compensatory changes in the unfused spinal segments, pelvis, and the lower extremities. Similarly, reciprocal changes in the thoracolumbar spine may harmonize global sagittal alignment after the cervical reconstruction. This study reviews the compensatory mechanisms and reciprocal changes in global sagittal alignment caused by the surgical correction and highlights, the factors that should be considered while assessing a patient’s compensatory status.

Study Design: Cross-sectional study.Purpose: To report the prevalence and relationship of developmental cervical and lumbar spinal stenosis (DCSS and DLSS) with the bone parameters of the skull and extremities.Overview of Literature: DCSS and DLSS are found occasionally in daily practice. DCSS and DLSS can cause compressive myelopathy, radiculopathy, and cauda equina syndrome; however, data on their prevalence and correlation with skull and skeletal extremity profiles is scarce.Methods: A cross-sectional measurement study of 293 whole-body dried-bone samples was conducted. We measured the anteroposterior (AP) and transverse diameter of the fourth to sixth cervical vertebrae (C4–C6) and third to fifth lumbar vertebrae (L3–L5). Stenosis of the cervical spine and lumbar spine was defined as an AP diameter of <12 mm and <13 mm, respectively. We also measured the skull circumference, the AP and transverse diameters of the foramen magnum, the inner and outer inter distances between the left and right orbital bones, the humerus length, and the femoral length. Kruskal-Wallis and post hoc analyses were used in the statistical analyses.Results: The age was 22–93 years. DCSS was found in 59 (20.1%) and DLSS in 28 (9.6%). Twelve samples had both DCSS and DLSS (development spinal stenosis, DSS). When compared to the “no spinal stenosis sample,” DSS (−), DCSS and DSS had a significantly smaller skull circumference, the transverse diameter of the foramen magnum, and inner and outer distance between the orbital bone (p<0.05). There was no significant difference in humeral length, femoral length, or AP diameter of the foramen magnum.Conclusions: DCSS was correlated with a small skull, a small transverse diameter of the foramen magnum, and a small orbital bone. A small skull was strongly associated with a small cervical canal. DLSS, on the other hand, was unrelated to either a small cervical canal or a small skull.

Published: May 2022

From the Nineteen Eighties to the present, Pakistan's mounting debts have been the subject of debate and consideration by policy makers and economists. Unfortunately, foreign debt is one of the biggest significant issues which downsize Pakistan’s Economy. This study aimed to investigate the effects of external debt restructuring on the country's economic system. The objective was to study the various factors that affect Pakistan's economy, such as external debt, growth,saving, and foreign direct investment. Annual panel data was taken from the World Bank and used to manipulate the results. External debt is the main factor that harms the country's structured variable GDP, economic condition and growth as well. It has been concluded that Pakistan should consider debt forgiveness and invite foreign direct investment. Although exports are beneficial to the country's economy, they should be lifted to increase its financial system. The adverse effects of external debt on the boom are very apparent now a days.

Published: May 2022

BACKGROUND

Although an anterior cranial fossa dural arteriovenous fistula (ACFdAVF) is thought to have a fistula on the dura near the olfactory groove, the detailed angioarchitecture remains unreported.

OBSERVATIONS

In case 1, a 65-year-old man was found to have an asymptomatic ACFAVF. His computed tomography angiography (CTA)-maximum intensity projection (MIP) showed the shunt point in the crista galli (CG), with the intradural drainer penetrating the destroyed bone of the CG. In case 2, a 78-year-old man had a past history of intracerebral hemorrhage and was found to have an ACFAVF. The rotational angiography (RA)-MIP showed the intraosseous fistula in the CG with the drainer passing through a tiny bone defect of the CG. In case 3, a 35-year-old man was investigated for epilepsy. The RA-MIP showed an osseous arteriovenous fistula (AVF) in the anterior cranial base, with the drainer penetrating the skull osteolytic site. In case 4, a 73-year-old woman was found to have an asymptomatic ACFAVF. Her RA-MIP showed the osseous AVF with the drainer penetrating the CG with bone erosion.

LESSSONS

All patients were diagnosed with anterior cranial fossa osseous AVF rather than dAVF, with bone erosion in the CG. These findings should be noted at the time of diagnosis and treatment.
Introduction to Qualitative Evidence Synthesis as a Methodology
Authors: Costa King
Published: May 2022

The outbreak of COVID-19 has disrupted research methods just as it had to all other sectors of education across the globe. Many institutions and organisations, including researchers sought to find ways to deal with research while observing the requirement for remote interactions. While many options have been implemented, the use of systematic reviews, and in particular, Qualitative Evidence Synthesis (QES) have not been explored. QES, as a research method, offers a high level of evidence through the synthesis of primary qualitative studies, using established and endorsed critical appraisal methods such as PRISMA Workflow charts or COREQ, CASP (the latter is commonly used in QES), and many more that are suitable based on the nature of the study design. The other beneficial quality of QES is the ability to preserve research, use and embellish primary research and provide formidable networks among researchers. This presentation was first presented at a workshop organized by the National Center for Research Methods and the University of Manchester (UK) in October 2021 and later on at the 6th World Conference on Qualitative Research (Spain) in January 2022.
Effect of arbuscular mycorrhiza fungi on the growth, nutrient uptake, root infectivity and soil colonisation of rough lemon (Citrus jambhiri) seedlings
Authors: INNSPUB International Network For Natural Sciences , Chebet DK
Published: May 2022

The effect of Arbuscular mycorrhiza (AM) fungi on growth, nutrient uptake and root infectivity was determined in Rough Lemon (Citrus jambhiri) seedlings raised under four phosphorus regimes in sand culture and also in sand/nitrosol sterile and unsterile conditions. Inoculation with AM fungi increased the plant height, leaf number and stem girth in relation to un-inoculated seedlings grown under equivalent P concentrations. An increase in plant height, leaf number and stem girth also occurred in both inoculated sterile and un-sterile sand/nitrosol media in relation to un-inoculated sterile and unsterile media. Arbuscular mycorrhiza also increased the leaf area and the root, leaf and stem fresh and dry weights and also caused an increase in the uptake of phosphorus and potassium in the leaf tissues. It also favoured mycorrhizal infectivity of roots and increased the root absorptive surface area. This study indicates that AM fungi improves the capacity of tropical fruit to absorb and utilize plant nutrients possibly by increasing the effective root surface area from which available form of nutrients are absorbed and also by increasing access of roots by bridging the depletion zones. Inoculating seedlings with arbuscular mycorrhizal fungi helps to alleviate the adverse effects of global warming and climate change. As a low cost technology, arbuscular mycorrhizal inoculation is recommended as part of the regular practise for incorporating into nursery media used for tropical fruit seedling propagation.

Economic analog of Heisenberg uncertainly principle and financial crisis
Authors: Soloviev V. N. , Romanenko Y. V.
Published: May 2022

The Heisenberg uncertainty principle is one of the cornerstones of quantum mechanics. The modern version of the uncertainty principle, deals not with the precision of a measurement and the disturbance it introduces, but with the intrinsic uncertainty any quantum state must possess, regardless of what measurement is performed. Recently, the study of uncertainty relations in general has been a topic of growing interest, specifically in the setting of quantum information and quantum cryptography, where it is fundamental to the security of certain protocols. The aim of this study is to analyze the concepts and fundamental physical constants in terms of achievements of modern theoretical physics, they search for adequate and useful analogues in the socio-economic phenomena and processes, and their possible use in early warning of adverse crisis in financial markets. The instability of global financial systems depending on ordinary and natural disturbances in modern markets and highly undesirable financial crises are the evidence of methodological crisis in modelling, predicting and interpretation of current socio-economic conditions.

Authors: Демиденко Г. Г.
Published: May 2022

У статті розглянуто специфіку втілення у фразеології рис національного характеру українців. Звернено увагу на особливості стійких зворотів, пов’язаних з невербальною взаємодією лінгвоносіїв. Обґрунтовано думку, що сталі вислови з паралінгвальним компонентом дають змогу осягнути національний спосіб світосприйняття, комунікативний досвід народу, стереотипи поведінки; зокрема акцентовано на їх культурній детермінованості на східнослов’янському мовному тлі.

Професійна спрямованість фундаменталізації інформатичної освіти
Authors: Поліщук Олександр Павлович , Теплицький Ілля Олександрович , Семеріков Сергій Олексійович
Published: May 2022

За В. Д. Шадриковим, професійна спрямованість формується у мотиваційній сфері та являє собою «систему мотивів, що спонукають професіонала до виконання професійних завдань та задач професійного розвитку. В якості мотивів виступають потреби, інтереси, установки, переконання, ідеали та інші психологічні утворення людини. Головна їх особливість полягає в тому, що вони ... реалізуються в процесі виконання професійної діяльності чи розв’язування задач професійного розвитку».
Застосування методів машинного навчання у навчанні моделювання майбутніх учителів хімії
Authors: Семеріков С. О.
Published: May 2022

Починаючи з 2018-2019 н. р., для магістрантів з додатковою спеціальністю «Інформатика» уведено навчальну дисципліну «Чисельні методи та моделювання», спрямованої на формування у студентів системи теоретичних знань з основ апарату чисельних методів і практичних навичок їх використання для розробки та дослідження математичних моделей. Одним із провідних завдань дисципліни є надання комплексу знань, необхідних для розуміння проблем, які виникають під час побудови та при використанні сучасних інтелектуальних систем, та ознайомлення студентів з основними принципами нейромережевого моделювання: – загальними характеристиками біологічних та штучних нейронів; – штучною нейронною мережею Хебба, класичним та модифікованими перцептронами; – видами функцій активації, що набули поширення в штучних нейронних мережах; – технологією проектування одношарових та багатошарових штучних нейронних мереж; – алгоритмами навчання нейронних мереж. Вказані питання в останні десятиріччя розглядаються у межах машинного навчання (Machine Learning) – розділу штучного інтелекту, що розглядає методи побудови алгоритмів та на їх основі програм, здатних «навчатися» шляхом подання емпіричних даних (прецедентів або спостережень), в яких виявляються закономірності, та на їх основі будуються моделі, що надають можливість у подальшому прогнозувати певні характеристики для нових об’єктів. На жаль, класичний (і найбільш популярний у світі) курс машинного навчання Е. Ина (Andrew Ng), розміщений на платформі Coursera, зорієнтований насамперед на студентів-початковців інформатичних спеціальностей – це надає можливість пропонувати його для самостійного опрацювання, але не розв’язує основну проблему: надання змістовних моделей, що відображають специфіку основної спеціальності – хімія.

It is demonstrated that one of the conditions for successful scientific and pedagogical work is exchanging of methodical materials, including with using of augmented reality. We propose to classify approaches of placing methodical materials on closed, open and open-moderated types. One of the important benefits of a closed type is the high quality of the methodical material, but it’s limited by amount of material and the lack of exchange opportunities that are problems, and there are no open-moderated resources in the Ukrainian language. The aim of this article is to analyze approaches of systematization of methodical material with using of augmented reality and recommend using of STEMUA for systematization of them. It is shown that STEMUA allows teachers to develop methodical material and place it on this platform. The platform automatically organizes methodical material in the database. Consequently, the platform is satisfying the methodical needs of Ukrainian teachers for material with using of complementary reality in the teaching. It is recommended for teachers and methodists to provide development and methodical materials with using of augmented reality and add them to the platform database.

Роль образного мислення в процесі формування історичних знань учнів. Від фактів до понять
Authors: Комаров Володимир Олексійович
Published: May 2022

Доведено, що одним із ефективних засобів активізації історичної уяви учнів є твори художньої літератури. Використання відповідних уривків може до певної міри компенсувати брак інших видів наочності. Але, як свідчить практика навчання, найбільш вагомих результатів у навчанні історії можна досягти за умови комбінації різноманітних видів наочності.
