ВПРОВАДЖЕННЯ SMART-ТЕХНОЛОГІЙ У ПРАКТИКУ ПІДГОТОВКИ МАЙБУТНІХ ВИКЛАДАЧІВ МЕДИЧНОГО ЗАКЛАДУ ВИЩОЇ ОСВІТИ
Authors: Кліщ Ірина
Published: July 2021

Статтю присвячено актуальній проблемі впровадження Smart-технологій у практику підготовки майбутніх викладачів медичних ЗВО. Під поняттям “Smart-технології” розуміємо інформаційні технології, спрямовані на розвиток компетентностей учасників освітнього процесу, необхідних для успішної діяльності в умовах цифрового суспільства.

Досліджено, що тенденції переходу до Smart-технологій формують і нові вимоги до підготовки майбутніх викладачів: передбачають не подачу “готових” знань, а створення умов для придбання молоддю власного досвіду і навичок. Тобто за концепцією Smart-навчання функцією викладача стає не трансляція готових істин, а якісна навігація контентом. Smart-технології дають змогу проводити динамічні презентації, демонструвати документи, сторінки Інтернету або відео на інтерактивному екрані, що сприяє підвищенню інтересу та поліпшенню концентрації уваги студентів і, як результат – кращому засвоєнню навчального матеріалу.

У статті здійснено аналіз відображення у науковому дискурсі української педагогічної компаративістики концептуальних засад (методологічних підходів, мети, принципів тощо) іншомовної освіти в зарубіжних країнах. Для репрезентативного вивчення цієї проблеми методом головного масиву охоплено близько 70 дисертацій і 20 монографій, а вибірковим методом – майже 100 статей. Принципи іншомовної освіти визначено як вихідні базові положення, що проєктують її функціонування у зарубіжжі. Визначено три домінуючі підходи українських учених до тлумачення принципів іншомовної освіти. Перший – формалістичний, коли вони ототожнюються із загальними принципами розвитку системи освіти України або досліджуваної країни. Другий підхід полягає в ототожненні принципів іншомовної освіти з принципами навчання іноземних мов; третій – передбачає їхнє визначення на основі основоположних міжнародних і європейських нормативних документів та національних державних нормативно-правових.

Among the major changes that have occurred in the tourist sector in recent years, of particular note has been the constant emergence of new products that seek to satisfy the needs of tourists demanding new kinds of consumer experiences. A good example of this is agritourism, in which the tourist participates in the typical activities of a working farm. This study focuses on a recent variant of this type of tourism, known as vegetable tourism (or holeriturismo in Spanish). Specifically, an assessment is undertaken of a pioneering project in Spain on an agricultural park: the Parc Agrari del Baix Llobregat (Barcelona). Based on the information obtained from a survey conducted in the Park itself, the degree of visitor satisfaction with the various activities they experience is analysed. Using non-parametric statistical methods, the study seeks to determine whether the visitors’ socio-demographic profile and their knowledge of the concept of vegetable tourism have a significant impact on their assessments.

Published: July 2021

The modern literature extensively considers the process of technological innovations and the results of the activities of market-oriented organizations. However, there are no studies of the process of technological innovations and the results of socio-technological enterprises that are formed to create social value through the use of technologies. The paper presents a conceptual model of how the investments of socio-technological enterprises in technological innovations implemented in the process of innovation implementation affect their market and social strategic orientation. The author considers these investments in innovations at four levels of analysis: founders, innovations, organization, and the external environment. The presented model and proposals promote and enrich the current literary sources regarding the factors that affect the balance of the strategic orientation of socio-technological enterprises between the social and market orientation.

Published: July 2021

The advent of digital social media in China has altered our understanding of who sets the policy agenda and forms public opinion. Using text mining analysis of more than 74,000 Weibo user comments (over 4 million words) on 6 years' worth of The People's Daily media coverage, this study investigates social media interactions on family planning policy issues between the state-run news media and individual users in China. Our analysis demonstrates that Weibo postings about the topic by government-run news networks and comments by the general public are affecting each other, but also presenting partially reverse or bottom-up agenda-setting effects. Through latent dirichlet allocation (LDA) modeling, we identified major latent topic sets (women's right to work, family culture/tradition, law/regulation, and social welfare/wellbeing) and found that Weibo users' main concerns on China's family planning have changed over time. We also found that gender differences affect the topics of commenters.

Authors: AKGÜN Mine , KAMACI Hayrünnisa Aydan
Published: July 2021

In this study, the effects of the structural parameters forming automobile seat cover fabrics on the comfort properties (such as water vapor permeability, air permeability and thermal resistance properties of fabrics) that may affect the vehicle usage performance of the person were examined. The seat cover fabrics used in the experimental study had not undergone any special finishing processes and it was aimed to evaluate the direct (without any special treatment) effect of the basic structural parameters that make up the fabric. Thus, it was considered that the fabrics used in the seat covers during the usage or after the treatments such as seat cleaning would create an important design input in terms of the breathability of the seat cover fabric and its sustainability throughout the lifetime of the car. As a results of this research, it was observed that thickness, weight per unit area and weave structure of seat cover woven fabrics have an important effect on the water vapor permeability, air permeability and thermal resistivity properties of the fabrics.

Published: July 2021

Kingpin parts are the critical product for heavy vehicles and are generally made of 20MnCr5 steel. A kingpin is a heavy metal cylindrical pin that is located underneath the front end of the trailer. The kingpin is the mechanism on the trailer that locks it to a road tractor. The parts in this study have undergone to case hardening heat treatment after the rough machining operation. During the operation in the assembly line, cracks have been shown on the parts surface. In this study, kingpin parts are examined with Scanning Electron Microscopy (SEM) analysis, hardness and %C potential analysis in order to determine the potential causes of crack formations. It is shown that, heat treatment of the parts is not homogeneously distributed and therefore fractures occur. The exact outcome of the fracture could not be determined. Under the scanning electron microscope, it becomes clear that it is a crack. There are no signs of hydrogen embrittlement. With the present structure, it is to be expected that even a low dynamic load can lead to breakage. As a result, investigations suggest that the parts have exposed to incorrect heat treatment parameters.
High Voltage Gain Multi-port Bidirectional DC-DC Converter with an Effective Multi-loop Control Strategy for PV/Battery Integrated Systems
Authors: SAVRUN Murat Mustafa , ATAY Alihan
Published: July 2021

This study proposes a novel isolated bidirectional multiport converter (MPC) based on a switched-capacitor converter and a half-bridge converter with an effective control scheme for photovoltaic (PV) powered and battery buffered systems. The proposed power electronics converter interface integrates the converters to which the ports are connected with a battery coupled common dc busbar and high frequency transformer (HFT). Thus, the three-port converter is formed without any need for an additional converter to regulate battery power flow. In addition, to transfer power from a low voltage PV energy unit to the battery and load, a single switch DC-DC converter with high voltage gain is proposed. The power flow between the ports is controlled by an effective multi-loop control scheme that is able to perform a smooth transition between the loops. In order to validate the viability and effectiveness of the proposed MPC, a 3 kW proof-of-concept model has been developed with a 3 kW PV and 220 V 12 Ah battery. The performance of the proposed converter has been analyzed for different case studies, including dynamic operating and loading conditions.

Синтезирован и охарактеризован летучий комплекс иридия [Ir(cod)Cp] (Cp — циклопента­диенил, cod — 1,5-циклооктадиен). С помощью метода термогравиметрии показано, что вещество переходит в газовую фазу в одну ступень, без заметного разложения. Методом РСА расшифрована структура [Ir(cod)Cp]. Анализ поверхности Хиршфельда, а также распределения электронной плотности и ее топологии в рамках теории AIM показал наличие множества межмолекулярных контактов, из которых наиболее сильными являются C(Cp)⋯H(Cp), Ir⋯H(Cp), H(cod)⋯H(cod). Наличие данных контактов в кристаллической структуре соединения приводит к более высоким температурам плавления и перехода в газовую фазу по сравнению с таковыми у аналогичного комплекса с метилзамещенным циклопентадиенилом. Расчеты энергии решетки и результаты термогравиметрического анализа для комплекса [Ir(cod)Cp], хорошо соотносятся с аналогичными данными для β-дикетонатных комплексов [Ir(cod)L] и позволяют предположить наличие корреляции между величинами энергии решетки и температурами плавления и 50 % потери массы.
Penyaluran Kredit dan Tingkat Likuiditas: Bukti Empiris pada Bank Umum di Indonesia
Authors: Bhoka Arnoldus Hesron , Yuniarti Sari , Burhan Mohammad
Published: July 2021

This paper examines the effect of bank lending on liquidity. We use the loan-to-deposit ratio as a proxy for liquidity and total loan as a proxy for bank lending. We also consider the measurement of liquidity with non-performing loans (NPL) and return on assets (ROA) as control variables. The sample used is the banks listed on the Indonesia Stock Exchange as many as 42 banks with a total of 184 observations from unbalanced panel data. The analysis used is panel data regression (generalized least squares) with random effects as the best estimation model. We find bank lending to have a positive effect on liquidity, especially for banks that go public. We argue that banks avoid bankruptcy by increasing the proportion of reserves to absorb risk. The results support the “risk absorption” hypothesis (Berger Bouwman, 2009). We also find that return on assets (ROA) has a significant effect on liquidity, but non-performing loans (NPL) have no significant effect on liquidity, proving that banks has managed their reserves by absorbing risk properly.

Introduction: Few studies are available to appreciate the broad spectrum of dive-related injuries (DI), which are not limited to decompression illness (DCI) and fatalities. Studies supporting injury-management efficacy from early recognition to first-aid, final treatment and outcome are also lacking. This study aims at making an epidemiologic inventory of DI among French scuba divers. Methods: This online, retrospective, cross-sectional survey analyzed self-reported symptoms, context of occurrence, initial response and outcome. The relationships between symptoms and diver characteristics were assessed and severity scores created from the reports. Results: A total of 799 divers responded, of whose questionnaires 784 were sufficiently complete to be analyzed. Approximately one-third (35%) of respondents had never experienced a DI. DCI-like symptoms represent a small fraction of DIs, the most commonly reported being ear barotrauma. Self-reported symptom rates decreased with increasing age and male sex. The ranking dive leader was the primary care provider in 58% of reports and 32% of injured divers never sought help. Management decisions (first aid and/or hyperbaric oxygen treatment) were related to the severity score. Complete resolution was achieved in 84 (74%) of 114 DCI cases, whilst mild (n = 22, 19%) and severe (n = 8, 7%) residual symptoms were reported. One in 10 divers who did not seek treatment for symptoms believed to be related to DCI declared some residual symptoms. Conclusion: Based on these results, diving injury rates may be higher than previously reported. However, the most frequent symptoms appear to be of only a modest nature.

Aim. The aim of the study was to differentiate the endotypes in allergic rhinitis by key allergy markers in a mixed group of patients.

Material and Methods. The study comprised a total of 48 patients, men and women, aged 18-60 years suffering from three endotypes of allergic rhinitis including the classic, local, and dual allergic rhinitis. The standard diagnostics of allergic rhinitis included taking a history of allergies, family history of allergic disease, video rhinoscopy, serum total IgE level assessment, allergy skin tests to house dust mite and pollen allergens, and study of eosinophilic inflammation parameters (eosinophil cationic protein, interleukin-5 (IL5), and eosinophil counts in blood and nasal secretion).

Results. Based on total IgE level, the general group of patients was divided to two subgroups: subgroup 1 comprised patients with high IgE level (n = 22); subgroup 2 comprised patients with low IgE level (n = 26). Most of patients in these groups had contradictory results of allergy skin tests i.e. positive allergy skin test results in case of high IgE level (group 1) and vice versa. Cluster analysis-based exminations of general group allowed to categorize three subgroups of patients: patients with classic allergic rhinitis (n = 22), local allergic rhinitis (n = 22), and dual allergic rhinitis (n = 4). Besides, an increased rate of anxiety disorder was found in patients with local allergic rhinitis (p < 0.001).

Conclusion. The obtained data showed promise for a new research trend in studying allergic rhinitis endotypes, namely: investigation of neuroimmune relationships in allergic tolerance disruption in the presence of this pathology.

Sex education should be given from an early age to prevent sexual harassment. Giving sex education to children is an effort to provide information about the function of the private parts. It makes them aware of sex and sexuality and the importance of taking them as privacy. It is also an opportunity to instill moral values and ethics. This community service employed a Service-Learning approach by utilizing adapted learning methods as well as adequate facilitators. In this program, sex education is given to grade 1 (as an early introduction) and grade 6 students (as they are approaching pre-puberty) at a primary school with material related to everyday life. This program ran for two weeks and received a satisfying response from the students and the school stakeholders. The result shows that the students understood the material very well. In addition, there is a reasonably positive behavior change in the students' awareness to take care of themselves in association with their classmates, especially those related to their private parts.
