Authors: Zheliabov Petro Oleksandrovich , Faizullin Dmytro , Kulabukhov Anatoliy Mikhaylovich
Published: March 2023

Recently, there has been a tendency to complicate real time control algorithms, to process a large amount of information from the satellite payload (optical, radar, communication systems) directly on board and to create highly informative communication lines with both ground stations and other satellites. The conditions of outer space (vacuum, radiation) impose significant restrictions on the computing capabilities of onboard equipment, which is used as an onboard digital computer complex, and lead to a significant increasing in the cost of space components. A high-performance and relatively cheap computing cluster structure of an on-board computer based on widely available single-board minicomputers is proposed, which allows distributing the computing load among several nodes and simultaneously backing up the system. As a component of a computing cluster, it is proposed to use a computing cluster system based on COTS (Commercial off-the-shelf) components, which increases performance by several orders while reducing cost. Calculations have shown that the introduction of redundancy and distribution of computational tasks makes it possible to achieve an MTBF of about 3 years, which is quite enough for the active existence of university satellites. The proposed structure of the onboard computer complex is installed on the university satellite for remote sensing of the Earth in the visible range with controlled optical magnification, after the launch of which it is planned to confirm the reliability of the results obtained in this work. An assessment of the performance and reliability of such a cluster system is given, which has shown the possibility of implementing such a system on a university satellite for Earth remote sensing.
ПРО ВПЛИВ ФОРМИ ГАЗОВОДУ НА ВЕЛИЧИНУ АКУСТИЧНИХ НАВАНТАЖЕНЬ ПРИ СТАРТІ РАКЕТИ-НОСІЯ З ОДНИМ СОПЛОВИМ БЛОКОМ

Published: March 2023

Під час запуску ракет космічного призначення використовують газодинамічний тип старту з відкритих стартових майданчиків. Він супроводжується виникненням величезних газодинамічних і акустичних навантажень, які впливають як на ракету-носій з корисним вантажем, так і на наземні споруди в цілому. Одним із шляхів зменшення цих навантажень є застосування газоходів з газовідбивачамиі зі спеціальною формою і габаритами. Мета цієї роботи - застосуванням моделювання чисельними методами показати, як змінюються акустичні навантаження при зміні геометричних параметрів газоходу. Виконано моделювання газодинамічного старту ракети зі стартового столу, де відпрацьовані струмені газу відводяться за допомогою газоходу (рис. 1, 2). Розрахунки виконані для моменту часу, коли відстань між зрізом сопла і входом в газохід дорівнює 9400 мм. Число Маха на зрізі сопла становить 3.95, а температура - близько 1820 К. Рівень нерозрахунковості при цьому становить 0.48. В ході роботи, глибина газоходу (h) приймає значення - 5500 мм, 6500 мм, 7500 мм, при цьому кут нахилу газовідбивача (φ) становить - 61.9о, 66.6о і 70о відповідно. У даній роботі моделювання газодинамічних процесів проведено із застосуванням нестаціонарних усереднених по Рейнольдсу рівнянь Нав'є-Стокса з використанням моделі турбулентності k-ω SST. Для оцінки акустичних навантажень використані моделі широкосмугового шуму. На основі результатів розрахунків побудовані картини розподілів числа Маха, тиску, температури, рівня акустичної потужності всередині газоходу. З'ясовано, що зі збільшенням глибини газоходу акустична потужність реактивного струменя практично залишається незмінною, але зменшується рівень акустичної потужності випромінювання шуму в середовищі. Розрахунки показали, що чим менше глибина газоходу, тим вище рівень акустичної потужності середовища. Наприклад, при h = 7500мм середній рівень акустичної потужності в середовищі знаходиться в діапазоні 90 ÷ 110дБ, то при h = 5500мм він вже становить 110 ÷ 130дБ.

Published: March 2023

The results of the design, development and testing of the laboratory model of the Hall Thruster ST- 22 are presented. The main attention in the development of the thruster was focused on the optimization of the magnetic field in the accelerating channel of the thruster. When choosing a constructive thruster diagram, it was proposed to use constant magnets and a non -magnetic ring in a magnetic system. The proposed constructive features of the thruster made it possible to exclude a magnetic screen from its design, which led to the simplification of the structure and reduce its mass. Laboratory tests of the ST-22 thruster were carried out when changing the discharge voltage in the range of 160-260 V, as well as with three different values of the mass flow rate of Xenon submitted to the anode - 0.4, 0.5, 0.6 mg/s. In the course of laboratory investigation of the ST-22 Hall thruster, the following characteristics were determined: current-voltage characteristics of the discharge in the acceleration channel of the thruster; the dependences of thrust and specific impulse on the mass flow rate of the working substance and the discharge voltage, as well as the value of the efficiency of the anode block of the thruster on the discharge voltage. As a result of laboratory tests, it was shown that at input power of 100 W, the discharge voltage 215 V and the working substance flow through the anode unit 0.6 mg/s, the thruster provides the thrust value of 7 mN, the discharge current of 0.47 A, a specific impulse of 950 s, and efficiency 33%. The values of the specific impulse and the thruster efficiency were given taking into account the mass flow rate of the working substance in the cathode-compensator. The thruster provides sustainable operation in the range of power consumption of 50 - 100 W and it was designed to use small spacecraft on board, which on board have appropriate electric power.
ЕКСПЕРИМЕНТАЛЬНЕ ДОСЛІДЖЕННЯ ДІАПАЗОНІВ СТАЛОЇ РОБОТИ КАТОДІВ-КОМПЕНСАТОРІВ ДЛЯ СТАЦІОНАРНИХ ПЛАЗМОВИХ ДВИГУНІВ

Published: March 2023

В умовах розвитку дослідження космосу зростають потреби до більш досконалих рухових установок космічних апаратів. Електрореактивні рухові установки (ЕРРУ) є найперспективнішими для систем орієнтації та корекції. Стаціонарний плазмовий двигун (СПД) - один з найбільш ефективних та перспективних двигунів ЕРРУ. Катод-компенсатор (далі – катод) – один з основних елементів СПД. Від катода залежить ресурс і стабільність роботи ЕРРУ. Раніше обмежувалися дослідженням роботи катода на кількох режимах. Це дозволяло визначити оптимальний режим роботи. Випробування більшій кількості режимів дадуть можливість прогнозувати характер роботи ЕРРУ з цим катодом. Також подібні газорозрядні катоди використовуються в двигунах з анодним шаром, для плазмово-іонних двигунів та як джерела плазми в іонно-плазмових технологіях. Випробувано в діодному режимі ряд безнакальних порожнистих газорозрядних високоемісійних катодів однієї моделі. Катоди випробували без кіперу, замість анодного блоку СПД до газорозрядного ланцюга підключати його імітатор. За допомогою вакуумної системи імітували умови експлуатації катода – граничний вакуум не гірший за 2∙10-5 торр. В якості робочого тіла застосовували ксенон. Для підтримки та регулювання роботи катода використовували стендові моделі системи збереження та подачі робочої речовини, системи живлення та керування. Вольтамперметрами вимірювали струм та напругу розряду. Витратомірами – масу робочої речовини, що подається на катод. Оптичним пірометром – температуру біля діафрагми катода. Отримано характеристики катодів – залежності температури і напруги від струму або витрати при встановленому четвертому параметрі. Досліджено сталість роботи катодів на одному режимі та характеристик катодів. При зниженні струму напруга зростає спочатку плавно, а потім спостерігається пік. Відзначено зміщення цього піку напруги у бік меншого струму зі збільшенням витрати. Показано, що катоди працюють найбільш стабільно на струмах, що відповідають горизонтальній частині вольт-амперної характеристики (зі сторони більших струмів від піку). Продемонстровано роботу катоду, що довго зберігався тому мав зміни емісійних властивостей поверхні матеріалу емітера.

Непараметрична статистика, дозволяє робити статистичні висновки, зокрема, оцінювати характеристики розподілу і перевіряти статистичні гіпотези, без, як правило, слабо обґрунтованих припущень про те, що функція розподілу елементів вибірки входить в ту чи іншу параметричне сімейство. Наприклад, широко поширена віра в те, що статистичні дані часто підкоряються нормальному розподілу. Тим часом аналіз конкретних результатів спостережень, зокрема, похибок вимірювань, призводить завжди до одного і того ж висновку - в переважній більшості випадків реальні розподілу істотно відрізняються від нормальних. У завданнях неруйнівного контролю -непараметрична статистика є основою для дослідження і прийняття рішень про придатність або якість виробів. Незважаючи на велику кількість публікацій з конкретних питань непараметричної статистики, внутрішня структура цього наукового напрямку залишається актуальною проблемою. Некритичне використання гіпотези нормальності часто призводить до значних помилок, наприклад, при відбракування різко виділяються результатів спостережень (викидів), при статистичному контролі якості і в інших випадках. Метою дослідження класичних методів непараметричної статистики в задачах спостереження за станом об'єктів контролю якості на основі виміряних величин. Методи.

Optimisation of stabiliser usage conditions in oat milk production using response surface methodology
Authors: Akal C. , Eminoğlu G. , Özer B.
Published: March 2023

Present study aimed to optimise stabiliser concentration and swelling time of oat in the production of oat milk using response surface methodology. The effects of independent variables (stabiliser concentration, swelling time) on dependent variables (rheological and sensory properties) were studied using a central composite rotatable design of experiments. Physico-chemical properties and colour values of samples were not significantly (P > 0.05) correlated to stabiliser concentration and swelling time. While stabiliser concentration affected the consistency index (P < 0.05), swelling time had no effect on the rheological properties. The stabiliser ratio affected the sensory texture of samples (P < 0.05). The sensory scores did not increase with increasing K value, on the contrary, the samples with the highest K value had lower sensory scores (P < 0.05). Considering the K value and sensory scores, the optimum stabiliser concentration and swelling time were determined as 0.102%, and 51.2 min, respectively.

Authors: Kadhim Fahad Mohanad , Jaber Jweeg Muhsin , Yousuf Al-Kkow Rowaid Nabeel , Al-Din Tahir Muhammad Safa
Published: March 2023

The pylon is an essential part of lower limb prosthetics. It is usually made of titanium, aluminum, and steel. However, it is expensive and difficult to be available in developing countries, especially for children who suffer from amputation. Moreover, they constantly need new pylon pieces during close periods due to the growth and increase in the child's length.

Purpose

This study aims to design an adjustable pylon that can change in length to suit the increase in the length of the healthy leg of the child without the need for a new pylon and reduce the economic cost.

Design/methodology/approach

In this study, an adjustable pylon model was designed using the CAD software (Solid work) and work to manufacture the pylon from low-cost materials (carbon fiber filament) capable of bearing the amputee's weight, and manufacturing printed parts by using additive manufacturing technical (CREALITY CR20 3D printer).

Findings

The results showed that the pylon is successful in design and strength as it bears the patient's weight without any failure or buckling, and the proof that the maximum amount of stress generated is 27.8 MPa, which is far from the value of the yield stress.

Originality/value

The design of the adjustable pylon prototype offers good strength and ability to bear the patient weight, reducing the cost and time of manufacturing.
Development of reassortant influenza vaccines: classical reassortment or reverse genetics?
Authors: Kiseleva Irina V. , Rudenko Larisa G.
Published: March 2023

An important feature of influenza vaccines, which distinguishes them from other immunobiological preparations, is that they have no fixed composition. Due to the constant influenza virus antigenic variability, production facilities require timely supply with relevant vaccine strains undoable due to the lack of proper method for the convenient, rapid and uninterrupted development of vaccine strains. Among the licensed influenza vaccines, classical inactivated and live influenza vaccines hold a special place. They are based on reassortant vaccine strains obtained by crossing currently circulating influenza virus with the so-called donor strain (cold-adapted attenuation donor for live influenza vaccines or high yield donor for inactivated vaccines). Vaccine strains for licensed live attenuated influenza vaccines are reassortants with the so-called 6:2 genome formula two genes encoding hemagglutinin and neuraminidase (HA and NA) belong to the current epidemic virus, and six genes encoding internal proteins (PB2, PB1, PA, NP, M and NS) to cold-adapted master donor virus. There is a very limited number of donors of attenuation. In Russia, there are cold-adapted viruses A/Leningrad/134/17/57 (H2N2) and B/USSR/60/69; in the USA (MedImmune) there are viruses A/Ann Arbor/6/60ca (H2N2) and B/Ann Arbor/1/66ca. MedImmune produces vaccine strains using reverse genetics technique. For other countries, this approach for obtaining vaccines is limited due to the need to purchase a license from the patent holders. In Russia, genetic manipulations with strains for the seasonal live influenza vaccine are not yet allowed; reassortants for the Russian live influenza vaccine are created only by classical reassortment in embryonated chicken eggs. Vaccine candidates for the inactivated influenza vaccine are prepared by the classical reassortment method, the requirements for them are more flexible and allow to use diverse genes combinations from wild type virus and master donor virus. High-yielding viruses such as A/PR/8/34 (H1N1), A/Texas/1/77 (H3N2), B/Lee/40 and some others are used as donors of internal genes. Unfortunately, the classical reassortment method does not always allow to promptly obtain a reassortant virus with a 6:2 genome formula. This is hindered by a number of reasons, ranging from the unique properties of a certain epidemic virus ending up with the constellation of genes. The reverse genetics method based on plasmids is an alternative approach to create reassortant vaccine strains allowing to reliably and quickly obtain reassortant viruses of a set 6:2 genome formula. However, this method also has certain weaknesses. This review discusses the advantages and disadvantages of development of conventional influenza vaccine candidates by reverse genetics and classical reassortment in developing chick embryos.

Authors: GERDAN Dilara , KOÇ Caner , VATANDAŞ Mustafa
Published: March 2023

Tomato is one of the most important vegetables in the world. Presence of diseases and pests in the growing area significantly affect the choice of variety in tomato. Early-stage diagnosis plays an important role in determining whether the tomato is subject to effective and economical chemical, mechanical and biological controls, and internal and external quarantine. In this study, deep learning was used to diagnose some diseases in tomatoes. For this purpose, a novel deep CNN-based approach and some Keras models including DenseNet201, InceptionResNetV2, MobileNet, VGG16 architectures were used. Early, middle, and late stages of 18.456 images of Bacterial Spot, Early Blight, Leaf Mold, Septoria Leaf Spot, Target Spot, Mosaic Virus, Yellow Leaf Curl Virus and healthy leaves were examined. The experimental results showed that the custom CNN model produced 99.82% training accuracy. We recommend this model in terms of monitoring and diagnosing of tomato diseases. The results obtained with this study can be used in robotic spraying and harvesting operations.

The Panel Analysis of the Effects of FDI and Export on the Economic Growth of CIS Countries
Authors:   The Korea International Trade Research Institute, Atajanov Temurbek-Ulugbek Ugli , Yi Chae-Deug
Published: March 2023

Purpose – This paper aims to examine the effects of foreign direct investment (FDI) and export on the economic growth of the Commonwealth of Independent States (CIS) and, based on the research results, provide some policy implications for the government of Uzbekistan. Design/Methodology/Approach – A panel data regression model and a panel dataset covering the period 1997 to 2020 were utilized for empirical investigation. The collected data were divided into two groups by income level and two groups by period, namely before and after the global financial crisis of 2008. This paper analyzes the aforementioned groups separately and provides a summary. Pooled OLS, fixed-effects models, and random-effects models were applied through panel data, and the Hausman test and the Breusch-Pagan Lagrange Multiplier test were performed. Findings – The findings corroborate the study’s hypothesis by proving that FDI facilitates growth in the former Soviet republics. Similarly, the comprehensive findings demonstrate that export is crucial for the economic growth of CIS countries, but the fixed-effects regression results for the first country group indicate that the influence of export on economic growth is insignificant when examined separately. Research Implications – The paper recommends that the government of the Republic of Uzbekistan enhance multilateral trade agreements to improve its international trade balance and adopt an export-stimulating strategy. To encourage FDI, the government should take steps to improve the country’s investment climate.

Published: March 2023

Purpose – The main purpose of this paper is to explore the national application of international law in the field of trade based on the possibilities and implications of law changes applied to trade between Korea and Europe. Design/Methodology/Approach – To analyze the possibilities and implications of law changes applied to trade between Korea and Europe, the paper focuses on the connectivity between international and national law based on literature research and legal texts. Specifically, it proposes a relationship between changes in the international community and international law on Korea-Europe trade based on the Korea- EU FTA and global challenges ahead of Korea and Europe. Findings – Since the European Union began to raise interest in Asia in the 1990s, relations between Korea and Europe have also developed rapidly. In particular, Korea and Europe have maintained close economic relations with the signing of the Korea-EU FTA in 2011, and discussions on international cooperation and the domestic application of international law have continued in the process. In this respect, the recent spread of international norms, including trade and sustainable development emphasized by the European Union, and the various global issues currently occurring, also have a significant impact on Korea-Europe relations and trade. Research Implications – The national application of international law centered on the Korea-EU FTA in establishing new cooperation between Korea and Europe in the future is likely to be revised, and new changes in the areas of a future Korea-EU FTA and international cooperation, such as well as recent global issues such as Brexit, the COVID-19 pandemic, and the Russia-Ukraine War.

In addition, by providing accurate information on luxury brands to stimulate intellectual curiosity and imagination, it is necessary to implement a brand strategy that induces strong attachment to the brand, and strengthens brand love.
A Thematic Review of Studies on Specific Learning Disabilities in Science Education
Authors: YAMAN Havva
Published: March 2023

As part of science education/science courses, students with special needs can develop their skills such as observing the events occurring in nature, making predictions and inferences. Given the characteristics of students with specific learning disabilities, it is crucial to reveal the developments of specific learning disabilities in science education to see the overall effect(s) of the teaching methods, techniques and others. The current study aims to thematically review the studies on specific learning disabilities within the scope of science education from the year 2009 to 2021. Considering the 2009-2021 date range and the criteria for specific learning disabilities in science education, a total of 43 studies were obtained from the relevant databases. The Thematic Content Analysis method was preferred. The studies were examined by considering the parameters of "distribution by years, aim, method, sample group, data collection tools, results, and recommendation". The results indicate that a limited number of studies were conducted on specific learning disabilities in science education and the researchers generally focused on elementary school students’ academic achievement and conceptual understanding levels employing quantitative methods. The results of the present study suggest carrying out studies in which in-depth analysis may be done selecting different sample groups (such as pre-service science teachers) for specific learning disabilities in science education and these may be conducted on the social and behavioral difficulties (loneliness, isolation and alike.) faced by students with specific learning disabilities in science education.

The integration of history of science (HOS) into science teaching plays a crucial role to address many shortcomings of traditional science teaching in middle schools, due to its close relationship to the nature of science (NOS) and to its ability to reveal the interconnectedness of science to other disciplines. The purpose of this study is to improve seventh grade students’ course engagement and motivation and their understanding of scientific concepts within the unit of “Force and Motion” through the use of history of science-based stories. The study was conducted according to an action research approach. Five stories based on the history of science were developed and administered by one of the researchers in their 7th grade science class. The iterative reflective practice took place over seven weeks with 15 students who met twice a week for two consecutive forty-minute sessions. Throughout this process, researcher journals, semi-structured interviews and a survey were employed for data collection. Teaching with history of science-based stories was found to be effective for students’ understanding of concepts related to “force and motion.” The results of the study were also positive with respect to the students’ engagement and motivation. Based on the findings, it is suggested that the nature of science should be addressed explicitly through stories in future research.

The purpose of this study was to provide a comprehensive understanding of Vocational School students’ experiences of learning English at a state university in Türkiye. After the application of a pre-survey which aimed to reveal the background of the students, four students took part in an interview about their English learning experiences in Vocational School. Interviews were also conducted with two instructors to obtain information about their perspectives of the Vocational School students’ English language learning motivation and process. Observations were also carried out in the real language classrooms. In data analysis categorical aggregation is used in order to have patterns in the qualitative data. The study unearthed the challenges that the students experienced in language learning process which were insufficient English background of students, their lack of motivation to general education, disregard to English education, and feeling of inferiority accompanied with low self-esteem. Furthermore, physical problems (students who are full or part-time workers), discontinuity in curriculum and limited lesson hours were also among the problems. The study implicated that information transmission which is still prevalent in lessons should be supported with other methods of teaching, the students need consciousness raising in terms of the place of English in their work life and some improvements are needed in the English curriculum.
НЕКОТОРЫЕ ПРОБЛЕМЫ НАРУШЕНИЯ АВТОРСКИХ ПРАВ В СЕТИ ИНТЕРНЕТ
Authors: КИРАКОСЯН Анна Эдуардовна
Published: March 2023

В развивающимся мире цифровых технологий появляются новые тенденции в контексте правовой охраны результатов интеллектуальной деятельности в интернете. Эволюция современных цифровых технологий диктует необходимость нового взгляда на механизм регулирования и защиты авторский прав в интернете. Создание и распространение незаконных копий произведений в виртуальной среде создают неблагоприятные условия для развития сферы медиаиндустрии, в значительной степени лишая правообладателей получения дохода от использования произведений.

В статье анализируется роль системы правовых норм, регулирующих авторско-правовые отношения в сфере создания произведений и реализации прав на результаты творческого труда в медиапространстве. Всеобщая компьютеризация, развитие компьютерных технологий, произошедшая в последние десятилетия цифровая революция все больше актуализируют роль медиаиндустрии и обусловливают необходимость создания прочного правового фундамента защиты авторских прав в глобальной сети Интернет.

Примечательно, что технологии, которые в настоящее время вызывают вопросы в законодательстве об авторском праве, связаны с такими признаками оцифрованного произведения, как легкость копирования, простота распространения и доступность хранения произведения, выраженного в электронной форме. Указанные свойства оцифрованного произведения создают почву для многочисленных нарушений авторских прав в интернете, наиболее распространенными из которых выступают плагиат и нелегальное распространение произведения, размещенного в интернете.

Автор выявила основные проблемы, связанные с несанкционированным использованием авторско-правового контента в информационно-телекоммуникационной сети, выделила наиболее распространенные цифровые правонарушения, имеющие место в сфере медиа и указала на необходимость создания оптимальных нормативных конструкций авторского права, нацеленных на прогрессивное развитие медиаиндустрии.

Автор исследует риски использования систем искусственного интеллекта в роботизированной/цифровой журналистике. Цели исследования — выявление типичных ошибок, влияющих на конечный результат, выдаваемый пользователям, а также вероятность привлечения к ответственности средств массовой информации и других лиц за распространение заведомо ложной информации при использовании в работе систем на основе искусственного интеллекта. Автор, анализируя последние изменения в законодательстве Российской Федерации и предлагаемые к принятию подзаконные акты, показывает тренд на усиление ответственности за распространение заведомо ложной информации. С учетом позиций российских и зарубежных исследователей автор выявляет тенденции развития цифровой журналистики в мире. На примере мнений исследователей искусственного интеллекта в журналистике показывает дуалистический подход к использованию его в средствах массовой информации. В статье приведены примеры использования ведущими средствами массовой информации систем искусственного интеллекта. Описаны характерные ошибки, допущенные системами искусственного интеллекта, использованными в журналистике. Анализируя законодательство Российской Федерации, автор определяет правовое положение искусственного интеллекта в действующем законодательстве и устанавливает круг лиц, ответственных за результаты работы искусственного интеллекта, выявляет некоторые пробелы в законодательстве, связанные с привлечением к ответственности за распространение заведомо ложной информации, показывает риски, возникающие при использовании систем искусственного интеллекта в цифровой журналистике. Автор делает умозаключение о необходимости человеческого контроля за использованием искусственного интеллекта в цифровой журналистике и необходимости устранения пробелов в законодательстве.

Production and perception of English consonants by Yemeni EFL learners
Authors: Bin Hadjah Najah Ahmed , Hamzah Mohd Hilmi
Published: March 2023

Many previous studies on the perception-production correlation focused mainly on transcriptions and native English speaker evaluations for production accuracy assessments; only a few included acoustic measurements. The purpose of this study is to examine the production and perception of six English consonants by Yemeni EFL learners of English using an acoustic measurement of L2 production in order to better understand the link between production and perception. It has three objectives: (1) To investigate the extent to which word position influences the accuracy of Yemeni EFL learners’ production of the target consonants, (2) to examine the extent to which word position affects their perception, and (3) to examine the relationship between the overall production and perception of the investigated sounds. A quantitative research method was employed to collect data from six Yemeni EFL postgraduate students from Universiti Utara Malaysia (UUM). In the production tasks, the speakers were asked to produce seventy-two words with the target consonants three times in isolation (Experiment 1) and the other three times in a carrier sentence (Experiment 2). The researchers recorded the speakers’ productions with an iPhone and later evaluated them acoustically via Praat. In the perception test, an AXB experiment was conducted. The stimuli were read by a native male speaker of Australian English. The findings showed that word position significantly affected the production, yet not the perception of the target sounds. Moreover, an insignificant positive moderate correlation was revealed between the overall production and perception of the target consonants. Results have implications for L2 speech and pronunciation instruction and learning. Teachers may focus more on specific sound environments that lead learners to struggle while producing/perceiving particular English sounds.

SİYASİ İLETİŞİM SÜRECİNDE AFİŞ TASARIMI VE GÖRSEL PROPAGANDA
Authors: Duydu Merve
Published: March 2023

Hedef kitleyi belli bir amaç doğrultusunda yönlendirirken tutum ve davranışlarını bir ideoloji etrafında şekillendirmenin en kolay yolu propaganda sanatını etkili şekilde kullanmaktan geçmektedir. Geçmişten günümüze iknanın en önemli araçlarından olan propaganda birçok tür ve tekniğin içinde faydalı olabilecek her türlü aracı kullanmaktan çekinmez. Günümüzde daha çok siyasal iletişimde zemin bulan propaganda faaliyetleri savaş dönemlerin de adeta silah olarak kullanılmıştır. Görsel iletişim yönü kuvvetli olan sanat dallarının kalabalığa ulaşmadaki etkisi, devletleri siyasi sarsılma dönemlerinde sanatsal propaganda faaliyetlerine yönlendirmiştir. Siyasi sarsılma dönemlerinde gerekli olan maddi ve psikolojik destek almada görsel sanatların uyarıcı gücüne başvurulmuştur. Bireylerden ziyade kitleleri hedef alan ve bunu yaparken kitle iletişim araçlarının görsel gücünden yaralanan propagandanın temel aktörlerinden biri afiştir. Bireylerin görsel hafızalarını tetikte tutan afişler kamusal alanları donatması bakımından hedef kitlesiyle zorunlu e sürekli bir beraberlik içerisindedir. Maddi kültürün aktif elemanlarından olan afişler toplumsal düzene katkı sağladığı gibi gerekli durumlarda bu düzeni eleştirerek değiştirmeye de çalışmaktadır. Afişin üretim ve dağıtım aşamasında ucuz olması ve diğer görsel iletişim araçlarına göre daha fazla kitleye ulaşabilmesi onun diğer iletişim araçlarına göre daha fazla tercih edilmesini sağlamaktadır. Toplum ile kültürel alışverişte olan afişler üretildiği dönemlerin, sosyolojik ve politik düşünce yapılarını yansıtmaktadır. Afiş tasarlandığı ülkenin kültürel ve sosyal özelliklerini yansıtan canlı ve estetik bir göstergedir. Topluma bilgi aktarmanın yanında estetik değeri de iyi olan afiş tasarımları mesaj iletmede oldukça etkin bir unsurdur. Bu açıdan değerlendirildiğinde: sanatın siyasi iletişim gücünü arttırdığını kavrayan devlet otoriteleri özellikle I. ve II. Dünya savaşı dönemlerinde kullandıkları afişlerle bir nevi propaganda yarışına girmişlerdir. Savaşın gerekli olduğuna halkı inandırmak ve orduya katılımı artırmak için kullanılan afişlerle hem kitlesel haberleşme sağlanmış hem de siyasi sarsılma dönemlerinin halk üzerindeki kabul süreci kolaylaştırılmaya çalışılmıştır. Bu çalışmada; siyasi kırılma dönemlerinde kullanılan afiş çalışmalarının siyasi iletişimdeki rolü incelenerek siyaset-propaganda ve sanat arasında ki bağlantı analiz edilmeye çalışılacaktır.
SİNEMA VE MİTOLOJİ İLİŞKİSİ ÇERÇEVESİNDE ALEV ALMIŞ BİR GENÇ KIZIN PORTRESİ FİLMİNİN ANALİZİ
Authors: Çöm Şenol
Published: March 2023

Mitoloji, insanın yaratılışından başlayarak onun doğa ve toplumla kurduğu ilişkiyi çok katmanlı ve alegorik olarak kuran oldukça önemli bir olgudur. Toplumların benliklerini oluşturan ve hayatı daha iyi anlamalarında onlara ilham olan mitolojik hikâyeler müzik, tiyatro, edebiyat ve sinema gibi sanatın farklı dallarında karşılık bulmuştur. Sinema mitleri tekrardan yaratmakla birlikte yeni mitler oluşturarak da anlatılmak isteneni yani ifade etme şeklini güçlendirmektedir. Aslında bu haliyle sinema toplumları etkisi altına alarak onların düşünme şekillerini yansıtmaktadır. Burada her ikisini benzer kılan en önemli unsur hayal ve gerçeğin adeta bir aradaymışçasına algılanmasıdır. Bu yüzden sinema, yaşamımızda mitolojinin tekrardan şekil alarak karşımıza çıkan bir başka yanıdır. Aynı mitoslar gibi sinemanın insan yaşamını değiştirici ve dönüştürücü unsurları bulunmaktadır. Bu çalışmada yönetmen Celine Sciamma’nın Alev Almış Bir Genç Kızın Portesi (ing. Portrait of a Lady on Fire) örneğinden hareketle Orpheus mitinin karakterler üzerinden nasıl yeniden yorumlandığı ve Orpheus'a olan bakışın kadın gözünden belirlenimini ortaya koymak amaçlanmıştır. Bu doğrultuda çalışmada felsefi eleştiri ve betimsel analiz yönteminden yararlanılmıştır. Film üzerinde yapılan analiz sonucunda Orpheus ve Eurydice gibi güçlü mitolojik öykülerle filmin arasında bir ilişkinin var olduğu, mitoloji ve sinema ilişkisinin metinlerarası olarak günümüz sinema öykülerine uzandığı sonucuna varılmıştır.

XVIII. Yüzyıl Şairi Tulûî ve Bağdatlı Rûhî nin Terkîb-bendine Naziresi
Authors: KOLUNSAĞ İbrahim
Published: March 2023

Bu makalenin çıkış noktası, İstanbul Üniversitesi Nadir Eserler Kütüphanesinde kayıtlı bir yazma eserdir. Kütüphane kataloğunda, Divan ve Mecmua-i Eş’âr başlıklarıyla iki bölüm olarak kaydedilen ve müellifinin XVI. yüzyıl şairlerinden İbrahim Tulûî olduğu belirtilen bu yazma, aslında XVIII. yüzyıl şairi olduğu anlaşılan başka bir Tulûî’nin eseridir. Üzerindeki karalamalar ve düzeltmelerle müellif hattı bir divan taslağı / müsveddesi görünümündeki bu eserde çoğunluğu oluşturan Tulûî’ye ait gazeller yanında şairle ilgili kişisel kayıtlar, farklı şairlerin şiirlerinden oluşan mecmua niteliğinde bir bölüm ve şairin Bağdatlı Rûhî’nin terkîb-bendine yazdığı bir naziresi mevcuttur. Hem bilinmeyen bir XVIII. yüzyıl şairini ve eserini tanıtmak hem de Rûhî’nin şiirine yazılmış nazirelere bir yenisini daha eklemek amacıyla bu makalede Tulûî’nin hayatı ve edebî kişiliği hakkında eserinden elde edilen veriler sıralanmış, naziresi şekil ve muhteva yönüyle incelenerek yayımlanmıştır. Genelde şiirlerinden ve özelde terkîb-bendinden hareketle yapılan değerlendirmelerde Tulûî’nin kendi üslubunu bulma çabasındaki bir şair olduğu, terkîb-bendinin de “usta şair izinde yazılmış bir nazire” seviyesinde olduğu sonucu vurgulanmış, ekinde ilgili nazirenin dijital görüntüleri verilerek makale tamamlanmıştır.
