Published: August 2022

Amorphous metallic alloys can be produced by rapid quenching from the metallic liquid at sufficient cooling rates to suppress the nucleation and growth of crystalline phases. The cooling rates required depend on the alloy constitution; generally the necessary values are in the order of 106 Ks-1[1]. There has been considerable interest in the manufacture of Fe-based metallic glasses because they possess attractive combinations of properties such as high hardness, good abrasive wear resistance together with enhanced corrosion resistance and good magnetic properties. However, in order to achieve these cooling rates in metallic alloy melts, samples less than 50 ƒÝm thick must be suddenly brought into good thermal contact with an efficient heat sink. Hence, these amorphous alloys are frequently produced in the form of ribbon or powder. An alternative approach consists to employ thermal spraying to deposit the alloys directly onto a substrate, in the form of a protective coating about 200 ƒÝm thick. In this study, FeSi powder was chosen as feedstock material. It is characterized by its good magntic properties [2- 7]. In order to control temperature and velocity of the in-flight particles during the coating deposition, on-line measurement of flame sprayed FeSi particles were performed with high-speed two-color pyrometer used especially for the spray forming process. In the same time, a wide band spectral pyrometer (LAND INFRARED) was used to monitor the coating surface temperature to ensure achieving good cooling rates. X-ray diffraction patterns show that the FeSi coatings structure present a crystalline phase and magnetic measurements indicate the soft ferromagnetic character of this last.

Published: August 2022

Plasma coating performances and lifetimes may be ruined during service conditions because of uncontrolled residual stress development within the coating. This study presents the results of a CAST3M thermomechanical numerical model which purpose is to simulate the different residual stresses development within the duplex coating-substrate during the coating built up and its comparison with the experimental results. To achieve the thermal spray process understanding all the thermal fluxes transferred to a metallic beam and surrounding temperatures were measured so as to provide the CAST3M model with precise boundary conditions, corresponding to a specific geometry. The residual stresses were experimentally determined by the in situ curvature measurement and, afterwards, by the hole drilling method. The plasma torch stand-off distance, the relative torch/substrate velocity and the substrate material were considered as the parameters of this study. The main results concern the substrate temperature and deflection during the preheating stage, the thermal energy transferred by the molten splats to the substrate together with the quenching stress and the development of thermal stress during the final cooling.

Published: August 2022

The photo catalytic TiO2 coatings on biodegradable plastic (polybutylene succinate: PBS) were prepared by using plasma splaying techniques. It is reported that there is a possibility that the performance of photo catalytic TiO2 coating may be advanced by addition of absorption ability [1]. It is also well known that the extraordinary absorption ability of HAP (hydroxyapatite) [2]. In this study, to investigate the influence of the addition of absorption ability to the coatings, not only pure anatase TiO2 powder but also two types of TiO2-HAP compound powder (TiO2- 10wt.%HAP, TiO2-30wt.%HAP) were used as thermal splay materials. The microstructure of coatings was characterized with SEM and XRD analysis, and some photo catalytic ability of coatings as a functional material was evaluated. One was the air purification performance of the coatings through the photo degradation of acetaldehyde gas, and the other was the sterilization performance to bacteria. In not only pure anatase TiO2 powder condition, but also in TiO2-10wt.%HAP and in TiO2-30wt.%HAP powder condition, the high anatase ratio which was approximately 95% were verified. In terms of decomposition ability to acetaldehyde gas, TiO2-10wt.%HAP coating was predominate to the others. This result indicates the addition of absorption ability. In terms of sterilization ability to bacteria and bacteria absorption, TiO2-HAP compound powder coatings showed a good performance.

Published: August 2022

Thermal cycle lifetimes of two thermal barrier coating (TBC) systems with the same plasma sprayed yttria-stabilized- zirconia (YSZ) topcoat but different low pressure plasma sprayed (LPPS) bond coats, conventional and cryomilled NiCrAlY feedstock powder, were studied. Thermal cycling tests consisted of 50 min at 1121C followed by 10 min air-cooling to room temperature. The coating produced with the cryomilled powder showed a 300% increase in lifetime when compared to the conventional one. Both TBCs failed as a result of delamination and spallation of the ceramic top coats. Several factors like thermally grown oxide (TGO) thickness, TGO composition, CTE mismatch, creep resistance of the NiCrAlY bond coat, and others that affected the thermal cycling life of the system, were analyzed in this work.

Published: August 2022

Nanostructured coatings of Al2O3 and ZrO2 (1.5% Y2O5) are produced by suspension plasma spraying, introducing the liquid feedstock internally into the central part of three converging plasma jets of a Mettech Axial III torch (Northwest Mettech Corp.). Spraying nanosized ceramic powders in a liquid carrier can yield thinner coatings with more refined microstructures than conventional plasma spraying. In-flight particle states are measured for a number of plasma conditions of varying torch current, gas flow rates and compositions (Ar, H2, N2), and related to the resulting microstructure and phase composition in the coatings, as determined by EDS, SEM and XRD. Results show that particle velocities up to 600 m/sec can be reached, yielding high impact velocities and cooling rates. Some comparison is made to previous work performed using external injection of a suspension droplet stream into a conventional dc plasma flame. At optimized conditions, dense γ-Al2O3 deposits with an average crystallite size below 30 nm are obtained at deposition efficiency above 80%, which was not previously attainable. Eutectic alumina-zirconia composite coatings with a finely layered lamellar structure are also realized. The laminates have potential advantages as thermal barrier coatings with beneficial properties arising from nano-composite components.

Authors: Said Maryam , Al Ani Mohammed Qasim Abdul Ghafoor
Published: August 2022

Cities are often divided by invisible borders, and this demarcation is man-made, with some areas featuring large infrastructure, well-maintained parks, gardens, and upscale residential areas. In contrast, other areas are characterized by severe deprivation, inadequate housing, inadequate services, poor recreation and cultural facilities, deterioration, and scarce infrastructure investment. These tangible differences come as symptoms of intangible and persistent divisions in society that distribute unequal opportunities and freedoms among the population. The research problem has shown the lack of clarity and diagnosis of urban problems that led to the emergence of the urban gap in cities). This paper focuses on breaking down the difficult edges created by the urban zoning of the city that would enhance interactions between communities and social classes through a practical study on a selected sample (Al-Hussein neighbourhood and Al-Intisar neighbourhood, Al-Muthanna, Iraq). The research concluded the importance of finding appropriate architectural and urban solutions and strategies to cross the urban inequality gap and achieve justice.

Authors: Hasibuan Ahmad Syukur
Published: August 2022

In the treatment of inflammation, there are several chemical drugs, namely steroidal and non-steroidal anti-inflammatory drugs, but because they have many side effects, anti-inflammatory drugs are developed from natural ingredients, especially plants. Plants are scientifically proven to have anti-inflammatory properties, one of which is ambarella fruit leaves because it leaves contain flavonoid secondary metabolites as anti-inflammatory compounds. The objective of this study to determine the effect of giving ambarella fruit leaves on anti-inflammatory activity in male rats induced by carrageenan. The method used in this study was paw edema, namely by induction of carrageenan 0.1 ml as an irritant on the soles of the rat's feet for 360 minutes with the parameter observed was the inhibition of edema in the feet of rats using a plethysmometer. This study was an experimental study that was divided into 5 groups, namely the control group positive (diclofenac sodium 9 mg/kgBW), negative control (Na-Cmc 0.55), and three doses tested, namely 100 mg/kgBW, 300 mg/kgBW and 500 mg/kgBW. The results of this study showed a significant difference (p<0.05) where flavonoid compounds from ambarella fruit leaves affect anti-inflammatory activity. The conclusion that the three doses is tested, namely 100 mg/kgBW, 300 mg/kgBW and 500 mg/kgBW has an anti-inflammatory effect where the more effective dose was 300 mg/kg kgBW.

Published: August 2022

Abstract: Compared with the state estimation of quadruped robots based on external sensors such as camera and lidar, the state estimation based on body sensors can provide high-frequency and stable odometer estimation. By analyzing the state estimation methods of the legged robot based on the body sensor, the invariant extended Kalman filter (IEKF) based on the body sensor is determined to conduct the state estimation analysis of the quadruped robot. Through various path tracking experiments in simulation and real environment, the influence of travel speed, travel distance and different steering angles on the position state estimation results was analyzed, and the IEKF model was optimized by compensating the angular velocity. Experiments show that within the set speed range, after adding angular velocity compensation, the position estimation accuracy error of the robot dog is well controlled and is less than 1%.
Epistemische Aspekte der Medienverbundenheit des Wissens
Authors: Przyborski Aglaja
Published: August 2022

Im Beitrag von Burkhard Schäffer werden „Möglichkeiten und Grenzen“ der Einbindung aktueller Medientechniken in den Forschungsprozess beleuchtet, besonders allerdings die Erweiterung einer die Dokumentarische Interpretation unterstützenden Software durch Künstliche Intelligenz (KI). In den Mittelpunkt stellt er Analogien zwischen sogenannten „Deep Learning“ Architekturen der KI und „Tiefer Interpretation“, mit der er die heuristischen Verfahrenslogiken rekonstruktiver Verfahren (Przyborski/Wohlrab-Sahr 2021) bezeichnet. Beide Formen der Transformation von Daten sind, wie Schäffer uns vor Augen führt, Operationen, die sich dem Prinzip nach explizieren lassen, aber nicht (mehr) in der konkreten zeitlichen Abfolge von Einzelschritten. Sie lassen sich daher seines Erachtens nach nicht methodisieren. Zudem beklagt er das rasche Verschwinden der Auseinandersetzung mit der epistemischen Bedeutung von Medientechnologien, nachdem sie Eingang in Forschungsroutinen gefunden haben. Beide Argumentationslinien werden kritisch diskutiert, um dabei zu zeigen, wie unterschiedliche Medientechnologien, die nicht nur konstitutiv für den Wissenschaftsbetrieb, sondern auch für den Alltag der sogenannten westlichen Gesellschaften insgesamt sind, systematisch in einen intersubjektiv überprüfbaren Forschungsprozess eingebunden werden können. Dabei spielen epistemische Überlegungen eine zentrale Rolle.
Educational research in (post-)digital spaces
Authors: Demmer Christine , Engel Juliane
Published: August 2022

Based on approaches of digital ethnography and using the work of Sofia da Silva as an example, we pose reflections on future shifts and innovations in the context of qualitative educational and biographical research: What methodological questions arise when current educational science objects are viewed from a (post-)digital perspective? We assume, among other things, that due to the interweaving of analogue and digital worlds new forms of biographization emerge, which require a theory-generating exploration of hybrid modes of experience as well as of the embedded interrelation of, for example, ‘body’, ‘education’, and ‘biography’. This could be achieved, for example, by a stronger mediation of ethnographic and biographical research approaches, or through an investigation of the connection between digital everyday practices, digitally mediated prefigurations and biographizations.

Published: August 2022

Background:

Neurofilament light is a marker of axonal degeneration, whose measurement from peripheral blood was recently made possible by new assays.

Objective:

We aimed to determine whether plasma neurofilament light chain (NfL) concentration reflects brain white matter integrity in patients with early Parkinson’s disease (PD).

Methods:

137 early PD patients and 51 healthy controls were included. Plasma NfL levels were measured using ultrasensitive single molecule array. 3T MRI including diffusion tensor imaging was acquired for voxelwise analysis of association between NfL and both fractional anisotropy (FA) and mean diffusivity (MD) in white matter tracts and subcortical nuclei.

Results:

A pattern of brain microstructural changes consistent with neurodegeneration was associated with increased plasma NfL in most of the frontal lobe and right internal capsule, with decreased FA and increased MD. The same clusters were also associated with poorer global cognition. A significant cluster in the left putamen was associated with increased NfL, with a significantly greater effect in PD than controls.

Conclusion:

Plasma NfL may be associated with brain microstructure, as measured using diffusion tensor imaging, in patients with early PD. Higher plasma NfL was associated with a frontal pattern of neurodegeneration that also correlates with cognitive performance in our cohort. This may support a future role for plasma NfL as an accessible biomarker for neurodegeneration and cognitive dysfunction in PD.
Calorie restriction causes multiple beneficial metabolic adaptations linearly related with the degree of weight loss in non-obese individuals: Results of CALERIE, a multicenter randomised controlled trial
Authors: Yang Lin , Veronese Nicola , Harper Andrew , Piccio Laura , Twigg Stephen M. , Fontana Luigi
Published: August 2022

BACKGROUND & AIMS:

Understanding the temporal association and relative power of anthropometric, body composition and energy metabolism measurements of calorie restriction (CR) in predicting metabolic and hormonal adaptations is important, given the clinical and public health implications of excess weight and adiposity.

METHODS:

Anthropometric (body weight, BMI, waist circumference), body composition (body fat and lean mass by DXA), energy metabolism (leptin and total daily energy intake by doubly labelled water [DLW]) markers and an extensive assessment of cardiometabolic, inflammatory and hormonal risk factors were obtained in 191, 21–50 year old non-obese (BMI 22·0–27·9 kg/m2) women and men, who participated in the 2-yr CALERIE randomized clinical trial. Pairwise correlations for each adiposity and energy metabolism measure were calculated against each other and against each metabolic parameter. In addition, spline and linear regression models were developed to determine a threshold effect of adiposity and energy metabolism measures to trigger changes in metabolic parameters.

RESULTS:

Among the progressively more sophisticated measures of adiposity, body weight is the variable that is most strongly correlated with cardiometabolic and inflammatory outcomes during CR-induced weight loss in young and middle-aged non-obese men and women. Waist circumference and DXA body fat are not superior to body weight or BMI in detecting these biological modifications. We did not find a specific threshold in weight loss to be exceeded for changes in metabolic and inflammatory adaptations to occur. Even small reductions in body weight cause a significant decline in serum T3 levels, a predictor of post-CR weight regain.

CONCLUSIONS:

Calorie restriction with adequate nutrition causes multiple beneficial cardiometabolic and hormonal adaptations that are linearly related with the degree of weight loss in non-obese individuals. Once a baseline has been established, tracking changes in body weight is sufficient to monitor improvements in metabolic health.

Published: August 2022

The need for reusable, interoperable, and interlinked linguistic resources in Natural Language Processing downstream tasks has been proved by the increasing efforts to develop standards and metadata suitable to represent several layers of information. Nevertheless, despite these efforts, the achievement of full compatibility for metadata in linguistic resource production is still far from being reached. Access to resources observing these standards is hindered either by (i) lack of or incomplete information, (ii) inconsistent ways of coding their metadata, and (iii) lack of maintenance. In this paper, we offer a quantitative and qualitative analysis of descriptive metadata and resources availability of two main metadata repositories: LOD Cloud and Annohub. Furthermore, we introduce a metadata enrichment, which aims at improving resource information, and a metadata alignment to META-SHARE ontology, suitable for easing the accessibility and interoperability of such resources.

Published: August 2022

The legal politics of applying Islamic criminal law (al-jinâ'iyyah) to national law is still debatable. This is because many factors encourage Indonesian Muslims to feel that Islamic criminal law is very appropriate to apply considering that positive criminal law (KUHP) has not been able to complete a sense of security and justice for the community, especially the victims. This writing aims to explain how the ideal form of transformation of Islamic criminal law to national law is intended so that Islamic criminal law can be accepted by all groups or is universal and does not conflict with the goals of the state in the state constitution as a preventive effort against criminal crimes. This research uses normative juridical research with historical, philosophical and hermeneutic approaches. The results of this paper reveal that Islamic criminal law has been enforced although not in its entirety due to assumptions that view Islamic law as a rigid law, inhumane law and cruel law, so there needs to be socialization to the community that Islamic criminal law is present as an alternative law in create legal guarantees and certainty.Keywords: Legal Politics; Transformation; al-ahkâm al-jinâ'iyyah. AbstrakPolitik hukum penerapan hukum pidana Islam (al-jinâ’iyyah) terhadap hukum nasional masih bersifat debatable.

Background and Aim: This study aimed to investigate the relationship between congenital heart disease found in fetal echocardiography with high nuchal translucency (NT) size found in fetal ultrasound in mothers referring to Hazrat Masoumeh Hospital, Qom City, Iran, in 2019. Materials and Methods: In this analytical study, information on all pregnant women who underwent ultrasound screening in the first trimester of pregnancy and their NT size was determined. Also, information obtained from fetal echocardiographic results, which were then subjected to fetal echocardiography, was extracted from the files. Then, the relationship between cardiovascular abnormalities with NT size and variables such as birth, weight, gestational age, and gender in these mothers were entered into a checklist and examined. Finally, the relationship between congenital heart disease and NT size was investigated using the t-test. Results: The Mean±SD NT size of 152 neonates without cardiovascular disease was 1.67±0.3 mm, and the Mean±SD size was 1.86±0.5 mm in 40 neonates with cardiovascular disease. Also, a statistically significant relationship was found between NT size and cardiovascular disease in neonates (P=0.00). There was also a statistically significant relationship was not found between neonatal gender (P=0.71), maternal age (P=0.88), as well as between number of pregnancies (P=0.26), NT size (P=0.76), type of pregnancy (P=0.63), gestational age (P=0.4), and NT size on ultrasound.

Published: August 2022

Background and Aim: The novel coronavirus 2019 (COVID-19) disease is a global pandemic with different presentations ranging from mild respiratory problems to severe septic shock. Previous studies have established the association between acute stroke and COVID-19. Herein, we describe the characteristics of patients with stroke during the COVID-19 pandemic. Materials and Methods: In this cross-sectional study, all patients with acute stroke referred to Bouali Hospital were enrolled from March to June 2020. The patients were categorized into two groups with and without COVID-19. Then, the demographic and clinical characteristics of stroke patients in both groups were evaluated. Eventually, SPSS software, version 22 was used to analyze the data. Results: A total of 61 patients with acute stroke were identified, of which 22 patients were positive for COVID-19. Except for the in-hospital mortality (P=0.07) and type of hemorrhagic transformation (P=0.02), we did not find a significant difference in the demographic and clinical characteristics of patients in both groups. The majority of patients with COVID-19 were severely symptomatic. However, the severity of chest CT involvement was significantly correlated with the mean modified Rankin scale (P=0.05). Conclusion: In this study, we revealed that acute stroke affected COVID-19 patients with traditional stroke risk factors at an age typically seen in non-COVID populations, which mainly constitute cryptogenic acute ischemic stroke. We also noted a higher in-hospital mortality rate in patients with COVID-19-associated stroke, which reflects a worse outcome of COVID-19. These results highlight the possible hypercoagulopathy state associated with COVID-19, which predisposes patients to develop stroke.

Background and Aim: Arsenic is an environmental pollutant that can damage tissue by producing free radicals. However, regular aerobic exercise is essential in enhancing antioxidant defense and resistance to oxidative stress. This study aimed to evaluate the effect of aerobic exercise on reduced glutathione (GSH) and oxidized glutathione (GSSG) and aortic endothelial cells of of heart tissue in rats exposed to arsenic. Materials and Methods: In this experimental study, 24 male Wistar rats with a weight ranged 220-240 g and a mean age of 6-8 weeks were divided into 3 groups of 8: healthy control, toxic control, and toxic aerobic exercise. Rats receiving arsenic were prescribed 25 ppm arsenic daily in oral water for 8 weeks. The exercise program consisted of 8 weeks of aerobic exercise, five sessions per week with an intensity of 75%-80% of maximum oxygen consumption. Eventually, 24 hours after the last exercise session, the rats were anesthetized and killed, and the target tissue was removed for examination. The Kolmogorov-Smirnov statistical test and one-way analysis of variance with Tukey post hoc test were used to analyze the findings in SPSS software, version 22 (P≥0.05). Results: Exposure to arsenic significantly reduced GSH and GSSG levels in heart tissue and aortic endothelial cells (P≥0.05). In contrast, aerobic exercise increased GSH and GSSG levels in heart tissue and aortic endothelial cells in arsenic-poisoned rats (P≥0.05). Conclusion: Aerobic exercise effectively reduces oxidative stress and increases antioxidant defense against arsenic toxicity in heart disorders.

У статті розглянуто особливості професійно-педагогічного становлення вчителя початкової ланки освіти на сучасному етапі розвитку освіти. Проаналізовано сучасні вимоги до професійної підготовки вчителів початкової ланки освіти, етапи становлення вчителя початкових класів, формування професійних компетентностей; уточнено зміст понять «професіоналізм», «педагогічна майстерність», «професійний розвиток», «професійна орієнтація і адаптація». Проблема визначення становлення та розвитку професійної педагогічної підготовки вчителів початкової школи актуальна, оскільки у процесі підготовки педагогічних кадрів нової генерації акцентується на розкритті особливостей етапів становлення та розвитку професійно-педагогічної освіти в Україні. Проаналізовано підходи вчених до визначення розвитку та становлення професійно-педагогічної підготовки вчителів початкової школи в Україні. Уточнено: адаптація вчителів до професійної діяльності являє собою складний динамічний тривалий процес систематичного занурення педагога в професію, що передбачає формування професійних знань, умінь, професійно важливих якостей, необхідних для подальшого розвитку; педагогічна майстерність − це вищий рівень педагогічної діяльності і прояв творчої активності особистості педагога, тобто, комплекс якостей особистості, який забезпечує самоорганізацію високого рівня професійної діяльності; професійний розвиток педагога полягає не тільки у зростанні і вдосконаленні професійних якостей особистості, але і руйнуванні і професійних деструкціях, які характеризуються змінами психологічної структури особистості в процесі педагогічної діяльності. З’ясовано, що на етапі становлення вчителя початкових класів професійна активність поступово стабілізується, рівень її прояву індивідуалізується залежно від психологічних особливостей.

Онлайн навчання набуває актуальності, а система викладання потребує перегляду, адже використання інноваційних методів і технологій дає більший спектр можливостей урізноманітнити діяльність студентів у процесі вивчення мови. Доступність інформації до різних джерел, ресурсів та інструкцій в Інтернеті розширює коло можливих засобів для ефективного навчання. Використання англійської мови як інструменту надає певні переваги фахівцям у їхньому конкурентному середовищі. Метою статті є узагальнити інформацію про інноваційні методи і технології в освітньому середовищі, з’ясувати їхні особливості і потенційні переваги. Процес вивчення мови побудований таким чином, що студент стає головним у процесі навчання. Викладач спрямовує енергію, завдання, враховує особливості цілей, навичок і задач, які має опанувати студент у кінці. Вивчення англійської мови і досягнення високого рівня у володінні мовою є істотним чинником для подальшого розвитку студента як особистості, вдосконалення навичок, набуття кваліфікації фахівця високого рівня. Навчання студентів із застосуванням інноваційних технологій дає можливість опанувати навички самостійного і критичного мислення, самостійно використовувати доступ до інформації англійською мовою, орієнтуватися в просторі міжкультурної взаємодії. Використання Інтернету збагачує можливості викладача і надає доступ до додатків та онлайн ресурсів для урізноманітнення освітнього процесу і доповнення заняття матеріалами з автентичних джерел. Сучасні періодичні видання мають онлайн версії та безкоштовні матеріали як для викладачів, так і для студентів. Інноваційні засоби допомагають долати психологічні бар’єри, досягти успішної взаємодії. Використовуючи онлайн джерела, студент має навчитись самостійно користуватися тим, що може почути і побачити в англомовному просторі, аналізуючи повідомлення і критично сприймаючи його.

Зосереджено увагу, що суспільству необхідні високоосвічені спеціалісти, здатні самостійно приймати кваліфіковані рішення, прогнозувати наслідки власних дій, готових до толерантного співробітництва, мобільні, динамічні, здатні до самоосвіти, спроможні не лише жити в громадянському суспільстві, але й активно створювати його. Відмічено, що провідниками соціальної політики держави виступають органи соціального захисту населення і від них, у значній мірі, залежить реалізація законів і нормативних правових актів, різного роду соціальних програм, пов'язаних із повсякденним життям і турботами багатьох людей. Обумовлено, що тільки кваліфікований, компетентний фахівець може прийняти усі виклики сьогодення і забезпечити ефективне виконання усіх завдань, що стоять перед сферою соціального захисту населення. Забезпечити підготовку такого фахівця у закладі вищої освіти можна на основі компетентнісного підходу. У зв'язку з цим важливим є формування інформатичних компетенцій та застосування інформаційно-комунікаційних технологій у підготовці майбутніх спеціалістів із різних напрямків соціального захисту населення. За результатами отриманого досвіду підготовки фахівців у закладі вищої освіти маємо змогу визначити інформатичні компетенції, якими повинен володіти майбутній фахівець сфери соціального захисту населення: створення ділових документів (листів, резюме, заяв, наказів, розпоряджень тощо) засобами текстового редактора; створення та використання активних шаблонів документів; застосування електронних таблиць для створення спеціалізованих калькуляторів і проведення обчислень, а також для візуалізації числових даних; планування робочого часу; створення презентацій; користування службами та сервісами мережі Інтернет; робота з таблицями, графіками, діаграмами (створення, аналіз); компетенція мови запитів та пошуку інформації в мережі Інтернет; робота з спеціалізованими інформаційно-пошуковими системами, базами даних та знань; застосування експертних систем; використання офісної оргтехніки (сканер, ксерокс, факс). Зроблено висновок про те, що набуття інформатичних компетенцій під час навчання у закладі вищої освіти здатне сприяти формуванню кваліфікованого фахівця відповідного рівня і профілю, конкурентноздатного на ринку праці.
