Published: September 2021

Keragaman Negara Indonesia dari mulai agama, suku, ras, bahasa dan lain, membuat Indonesia menjadi Negara yang sering terjadi konflik. Salah satu pemicu konflik yang paling sering adalah sempitnya masyarakat memahami agama Islam sehingga banyak diantara mereka menjadi eskstrimisme. Untuk mengatasi semua ini, diperlukan penerapan dari nilai-nilai ukhuwwah dan Islam wasathiyah. Nilai-nilai tersebut berupa sikap saling menyayangi, toleransi, tidak berlebihan dalam bersikap, bersikap ‘adil dan selalu mengedapankan kepentingan bersama dengan cara mufakat. Penelitian ini menggunkan penelitian library research (penelitian kepustakaan) dengan mengumpulkan semua sumber-sumber dari buku jurnal dan lain-lain kemudian mengkajinya kedalam kajian tematik dengan cara menulusuri ayat-ayat yang semakna.
Robust and Repeatable Biofabrication of Bacteria-Mediated Drug Delivery Systems: Effect of Conjugation Chemistry, Assembly Process Parameters, and Nanoparticle Size
Authors: Zhan Ying , Fergusson Austin , McNally Lacey R. , Davis Richey M. , Behkam Bahareh
Published: September 2021

Bacteria-mediated drug delivery systems comprising nanotherapeutics
conjugated onto bacteria synergistically augment the efficacy of both
therapeutic modalities in cancer therapy. Nanocarriers preserve
therapeutics’ bioavailability and reduce systemic toxicity, while
bacteria selectively colonize the cancerous tissue, impart intrinsic and
immune-mediated antitumor effects, and propel nanotherapeutics
interstitially. The optimal bacteria-nanoparticle (NP) conjugates would
carry the maximal NP load with minimal motility speed hindrance for
effective interstitial distribution. Furthermore, a well-defined and
repeatable NP attachment density distribution is crucial to determining
these biohybrid systems’ efficacious dosage and robust performance.
Herein, we utilized our Nanoscale Bacteria-Enabled Autonomous Delivery
System (NanoBEADS) platform to investigate the effects of assembly
process parameters of mixing method, volume, and duration on NP
attachment density and repeatability. We also evaluated the effect of
linkage chemistry and NP size on NP attachment density, viability,
growth rate, and motility of NanoBEADS. We show that the linkage
chemistry impacts NP attachment density while the self-assembly process
parameters affect the repeatability and, to a lesser extent, attachment
density. Lastly, the attachment density affects NanoBEADS’ growth rate
and motility in an NP size-dependent manner. These findings will
contribute to the development of scalable and repeatable
bacteria-nanoparticle biohybrids for applications in drug delivery and
beyond.

The influence of active learning and submicrorepresentations on 14-year-old students’ understanding of the alkaline earth metal concepts
Authors: Wissiak-Grm Katarina , Devetak Iztok
Published: September 2021

This study aimed to examine the impact of two different approaches on students? understanding of selected chemical concepts. The first treatment group was taught by a method comprising guided active learning demonstrations, and the second treatment group was exposed to guided active learning demonstrations with explanations at the submicroscopic level. In a control group, the selected topic was taught without guided active learning demonstrations and without explanations at the submicroscopic level. The instruments used in this research included the test of logical thinking (TOLT), knowledge pre-test (KPT), two achievement tests (AT-1 and AT-2) and a questionnaire for students. One hundred and seventy-one students (average age 13.9 years) participated in the study. The results indicate that both approaches (i.e., guided active learning demonstrations and guided active learning demonstrations with explanations at submicroscopic level) are more effective than only symbolic teaching. It can be concluded from the results that students? knowledge, obtained by either method that includes guided active learning, is retained in the students? long-term memory. Some suggestions for implications for the primary science curriculum are also discussed.
Tax Avoidance and Tax Disclosures in Corporate Social Responsibility Reports in the United Kingdom
Authors: Kao Wei-Chuan , Liao Chih-Hsien
Published: September 2021

This study examines how a firm's tax disclosures in a CSR report are influenced by its tax avoidance behavior. Using a sample of public U.K. firms, our empirical analysis reveals that firms engaging in higher levels of tax avoidance are more likely to provide tax-specific disclosures in their CSR reports. In addition, the tax disclosures tend to be longer, contain more justification words, and contain more soft claims than hard information. Further cross-sectional analyses suggest that the positive association between tax avoidance and tax disclosures is attenuated when firms exhibit better CSR performance as well as stronger corporate governance. Collectively, our findings provide evidence that firms appear to legitimize their tax avoidance behavior by providing more tax disclosures in their communications with stakeholders.

Published: September 2021

This paper presents the case of a 13-year-old female patient, operated in 2015 for left temporoparietal hydatid cyst and reoperated in 2016 for recurrence of the cerebral hydatid cyst. At admission, his GCS scores were E3V4M5. Neurological examination revealed a hemilatéral motor deficit estimated at 3/5 on right side without sensitive trouble. The CT scan showed a large left temporal cystic formation with an infected appearance associated with 4 cystic formations with calcified walls exerting a mass effect on the adjacent parechyma and the homolateral lateral ventricle responsible for a triventricular hydrocephalus. No primary focus was found in the lungs, liver, or other organs. In this article, we will discuss the management of complications related to hydatid cysts. Cerebral hydatid cyst is a rare condition, affecting mainly children. The diagnosis of cerebral hydatid cyst must be evoked in endemic countries in front of a symptomatology of intra-cranial hypertension.

Authors: Obrubov SA , Markelova SV
Published: September 2021

The growth of eye disease incidence in the juvenile population amidst increasing visual load, which, among other factors, results from the use of electronic devices (ED), outlines the search for effective preventive measures, geared towards preservation of health of young people. The study was aimed to assess the impact of life activity upon exposure to digital environment on the organ of sight in schoolchildren and college students. The study was carried out in 2017-2020 at Dolgoprudny gymnasium and Pirogov Russian National Research Medical University. A total of 805 schoolchildren and college students underwent ophthalmologic examination. Accommodative response was registered with Speedy-K Ver. MF-1 autorefractor keratometer (Japan). A standardized questionnaire, tailored by the authors to meet the requirements of the study, was used to assess the regime for the use of ED by students. Inclusion criteria: schoolchild, college student, ophthalmologic examination data and submitted informed consent available, correctly completed questionnaire. Statistical processing was performed using the Statistica 13.0 software. All students were the ED owners. Only 9.9% of primary school students, 2.7% of secondary school students, 1.9% of senior secondary school students, and 0.9% of college students did not use ED every day. Significant negative correlation was revealed between the students’ vision acuity and the daily total time of using the ED, as well as the duration of the ED continuous use (р≤0.05). Accommodation weakness was detected in 88.76% of students with early stage of myopia; accommodative response close to normal was less common (11.24%). The increase in daily total time of using the ED by 2 hours and more results in higher prevalence of functional vision problems (p≤0.05), and the trend of increasing the number of high myopia cases. The data obtained define the need of improving the students’ hygiene training starting from the preschool age.

Management Accounting Practices (MAPs) usage among Small and Medium-sized Enterprises (SMEs) and their implications are examined in this paper. 291 sets of questionnaires were dispersed and six interviews were conducted to gather the data. The usage frequency of individual practices and thematic analysis are deliberated, and the results denote the comparatively low MAPs usage rates among Jordanian SMEs as opposed to those in developed countries. Nonetheless, the reported rates in Jordan are comparable to those in developing countries. Among SMEs, MAPs significantly allow product cost information determination, planning and controlling, and detection of problems. Shortcomings of the traditional system, previous experiments of large companies, and external factors, are considered as the main reasons that motivated SMEs to use MAPs. Insufficient experience, lack of financial resources, and the high costs associated with implementing MAPs are the most crucial reasons that forced SMEs to neglect to use a lot of MAPs. The present study enriches the knowledge of MAPs in the context of SMEs. Also, the significance of MAPs among SME managers is highlighted. Equally, this study should stimulate additional scrutiny and analysis of MAPs amongst SMEs.

Authors:   Qatar University, Qatar, Mohd Idris Aftab , A. A. Ousama ,   Qatar University, Qatar
Published: September 2021

This study aimed to examine the relationship between board structure and firm performance measured by return on equity (ROE) and return on asset (ROA). 42 firms listed on the Qatar Stock Exchange (QSE) in 2018 were examined, using regression analysis. The study found that gender diversity (i.e., female directors on the board) had a positive significant relationship with firm performance in both measures, i.e., ROE and ROA. In addition, only board meeting and non-executive directors had significant relationships with firm performance measured by ROA. The findings of the study have some practical implications for some stakeholders, such as listed companies in Qatar and the Qatar Financial Market Authority. The Qatari listed companies will be able to understand the impact of board structure and the complementary benefits that may affect firm performance and thus strengthen the function of their boards. The Qatar Financial Market Authority will be able to understand the current practices of the corporate governance (CG) code; its strengths and weakness. Hence, it will be able to improve the code in order to overcome the weaknesses and strengthen good practices. Keywords: corporate governance, board independence, gender diversity, nationality diversity, firm performance
The Stalinist Past in Contemporary Russian TV Serials: Reconfigurations of Memory
Authors: Sukovata Viktoriya
Published: September 2021

The two main issues that continue to be in the focus of hot public discussions in Russian society are the Great Patriotic War (the German–Soviet war of 1941–1945, as part of World War II) and the tragedy of Stalinism. While the Great Patriotic War was widely reflected in Soviet literature and cinema, the Stalinist issue was seldom represented in Soviet art. In the 1980s and 1990s, there was a period when Soviet and post-Soviet art contributed much to the debates on the Soviet past, and several significant anti-Stalinist films and literary works were created. Since the early 2000s, the cultural situation in Russian society has changed and nostalgia of the Soviet past has spread in the mass consciousness. The purpose of this research is to analyze how the Stalinist past is reconstructed in public memory in contemporary cinema narratives. We arrive at the conclusion that since the 2000s, public interest has drifted from images of war heroism to ordinary people’ lives under Stalin; the contemporary public interest is not the war heroes and famous victims of repressions, but the everydayness of ordinary Soviet citizens who tried to build their private lives, careers, friendships, and family relations under the conditions of pressure from the authorities, spreading fear in the society, shortage of goods, and loss of loved ones. We concentrate on several representative Russian TV serials, such as “Liquidation” (2007), “Maryina Roscha” (2012), and “Leningrad, 46” (2014–2015), because all of them are devoted to the first year of the Soviet peaceful life in different Soviet cities, such as Odessa, Moscow, and Leningrad.

Intention to Use Self-Service Technology Based on Basic Human Needs
Authors: Widyarini Lydia Ari
Published: September 2021

In the context of technology developing in the society, Self-service technologies (SSTs) are becoming increasingly popular in retailing contexts, public service, banking, ticketing, parking, tourism, etc. Previous theories of SST adoption have largely ignored the basic human needs, such as competence, autonomy and relatedness that drive customer motivation and the use of SSTs in Indonesia. We address this theoretical gap and examine self-determination theory (SDT) to the Self Service Technology in general. Based on the argument proposed by SDT, self-determined motivation is hypothesized to mediate the relationships between autonomy, competence, and perceived anonymity, and the intention to use SSTs. Data collected from respondents form a structural equation model and support these hypotheses.

This research shows that there is relation autonomy and competence to self determination and adoption intention to SSTs. There is no good relation anonymity to self determination and adoption intention to SSTs. There is relation Self Determination to adoption intention to SSTs. Self Determination mediate relationship of autonomy and competence on adoption intention, but Self Determination is not good mediation relationship of perceived anonymity on adoption intention to SSTs.

Authors: Avatkov Vladimir Alekseevich , Kasianenko Aleksandr Vladimirovich
Published: September 2021

The research subject is the peculiarities of modern political-military relations in the South Caucasus in the context of the Iran-Russia-Turkey Triangle. The author considers political-military relations in the region through the prism of national interests of regional actors, such as Russia, Turkey, and Iran; analyzes military and technical cooperation in the South Caucasus based on the example of Armenia and Azerbaijan; studies military expenditure of the countries of the region and military budgets of Armenia and Azerbaijan, which are one of the hotbeds of tension and conflicts of interests of Russia, Turkey and Iran. The scientific novelty of the research consists in the systematization of ideas about the modern state of political-military relations in the South Caucasus in terms of the regional actors’ influence on the regional security system. Based on the documents, facts and research works, the author formulates a conclusion about the condition and the prospects of development of modern political-military relations in the South Caucasus in the context of the Iran-Russia-Turkey Triangle. The success of Turkey in terms of strengthening its positions in the South Caucasus against the background of rising competition in the region is undoubtable. Turkey has managed not only to position itself as a strong regional actor, which is able to indirectly influence regional disputes settlement, but also to promote the military triumph of Azerbaijan, its key ally in the region. It will result in further extension of export of Turkish weapons to Azerbaijan, and deeper cooperation between these two countries in other spheres. It concerns Russia and Iran, which are interested in maintaining the balance of powers in the region.

Authors: Ali Barham H. , Saeed Brwa A. , Hussein Twana A.
Published: September 2021

This paper develops the state-space representation (SSR) in the field of seismic analysis of the building structures. Dynamic analysis of multi-degree-of-freedom structures involves the solution of second-order linear differential equations which they represent the equation of motion of the structure. In this paper, a SSR was formulated to replace differential equation with two coupled first-order linear differential equations. The objectives of this study are as follows: (i) To implement the SSR as a powerful tool in dynamic analysis of frame structures and (ii) to conduct a linear time history analysis for large structures subjected to ground acceleration and the seismic responses of the building were studied as well. The analysis was based on the assumption that the system is elastic linear time-invariant system and material nonlinearity is not considered. The 1940 El-Centro earthquake time history record has been used in the study. There are many effective traditional methods which can be used for carrying out linear dynamic analysis of the structures, however, this paper introduces a state-space model as an alternative approach to perform this analysis. The advantage of this method, it works properly with MATLAB software, gives explicit result for time-invariant systems, applied to multi-input and multi-output control systems, solve the equation of motion for complicated dynamic problems.

Authors: Hadi Dlawar M. , Ahmed Farman M.
Published: September 2021

This study aims to explore the sensitivity of hotel stock prices to national and transnational terrorist incidents that occur at the world’s top five tourist destinations. Event study analysis and the generalized sign test are the estimation techniques used in this study. Overall, hotel stocks were found to react differently to terrorist activities. U.S. hotel stocks were the most affected, and French hotel stocks were the least affected by domestic terrorist attacks. However, U.K. hotel stocks were the most influenced and Thai hotel stocks were the least influenced by transnational terrorist incidents. Based on the overall findings, several diversification, hedging, and speculation strategies are proposed for mitigating the effects of these influences to financial market stakeholders and hotel managers. This study recommends further studies to be conducted including various sectors to reveal how different sectors react to terrorist activities.

Authors: Ahmed Omer K. , Daoud Raid W. , Ali Al-Mallah Ruaa H.
Published: September 2021

A numerical study is achieved on a new shape of temperature saver solar collector using an artificial neural network. The storage collector is a triangle face and a right triangle pyramid for the volumetric shape. It is obtained by cutting a cube from one upper corner at 45°, down to the opposite hypotenuse of the base of the cube. The numerical study was carried out using the computational fluid dynamics code (ANSYS-Fluent) software with natural convection phenomenon in the pyramid enclosure. Elman backpropagation network is used for his ability to find the nearest solution with the smallest error rate. The network consists of three layers, each of different corresponding weights. The results show that the temperature and velocity distributions throughout the operating period were obtained. The influence of introducing an internal partition inside the triangular storage collector was investigated. Also the optimum geometry and location for this partition were obtained. The enhancement was best at y = 0.25 m, whereas the height of triangular collector was 0.5 m. The hourly system performance was evaluated for all test conditions. The performance of the NN to train a model for this work was 0.000207, while the error of the calculation was 1×10-2 as average.

Authors: Muhammed Rozhan A. , Omer Huner K.
Published: September 2021

Fast dissolving oral film is a new emerging solid dosage form in which it consists of thin strips administered orally and dissolved in mouth within the seconds. The study is purposed to use water soluble polymers to provide rapid film disintegration as the films are hydrated in mouth and to find the best polymer type and its concentration to formulate the drug. Initially, placebo films were prepared using solvent casting method then two formulations from the prepared placebo films were selected to formulate imipramine. The excipients were dissolved in water then the drug solution was prepared by dissolving 150 mg of drug in 5 ml of water then mixed with the excipients and they were mixed gently and casted in disposable Petri dishes and left for 24 h in oven to provide film dryness. Then, the films removed from Petri dish and cut to 2 cm × 2 cm small strips. Then, the tests were performed. Successful films were prepared by 45% hydroxypropyl methyl cellulose (HPMC) and 50% sodium carboxymethyl cellulose (NaCMC). The films were smooth, easily removed from Petri dish without tearing and homogenous. The thin films were mechanically stable that they could be handled without breaking due to their good folding endurance which was more than 400. The pH of the films was accepted since they were around saliva pH (5.3–6.9). The films disintegration time was <60 min since water-soluble polymers were used and this property provided rapid drug release from the formulation in which it was 15–20 min for both of the drug-containing films, while dissolution time for the imipramine conventional tablet was about 60 min. Imipramine can be formulated as a new dosage form (fast dissolving film) using 45% HPMC and 50% NaCMC as polymer using solvent casting method to ease the drug administration for psychotic and pediatric patients since no water is required for this solid dosage for administration.

Authors: Ahmed Medhat Frzand K.
Published: September 2021

Field study works have been carried out to investigate the diffusion rate of oily wastewater on clayey soils and measuring the degree of contamination with chemical components for both horizontal and vertical directions. Three pits have been prepared for this work with 30 cm in diameter and 50 cm in depth, which are lying on a straight line and 100 cm clear distance between them. Three, 30 cm diameter plastic pipes were fixed inside the pits having the length of 50 cm, 150 cm, and 200 cm, respectively, to study the effect of the height of the spilled oily wastewater on the rate of diffusion. The pipes filled with oily wastewater separately, the diffusion rate with time has been recorded. The results showed that the vertical diffusion rate of the oily wastewater was increased with the increase of the height, while the longitudinal diffusion rate recorded lower values. The same observation has been noted for the degree of soil contamination.
Тува как лимитрофная зона: язык, религия и идентификация населения

В статье Тува рассматривается как лимитрофная зона — территория, которая находится между цивилизациями, испытывает их влияние в разных аспектах социокультурной жизни населения, не входит полностью ни в одно цивилизационное поле, а остается в пограничном положении. Это становится очевидным, если анализировать разные сферы социокультурной жизни региона. С одной стороны, Тува много веков развивалась как часть территории Внутренней (или Центральной) Азии кочевников, шаманистов, буддистов. С другой стороны, она уже два века также является и частью российской цивилизации. В жизни населения в разных аспектах доминируют разные цивилизационные влияния, что приводит к тяготению Тувы в разных вопросах к разным цивилизационным общностям.

В данной статье на обширном библиографическом материале, а также данных авторских эмпирических исследований рассмотрены цивилизационные влияния в сфере языков, распространенных у тувинцев — большинства населения республики, а также их религиозная приверженность и самоидентификация. В каждой из тем анализ включает историческую ретроспекцию, которая позволяет увидеть исторический выбор тувинцев в том или ином вопросе, появление того или иного фактора, его особенности.

Отмечается, что в сфере языка у тувинцев некоторое время существовал ограниченный тувинско-монгольский билингвизм, который затем сменился тувинско-русским и имеет тенденцию к постепенной смене с поколениями к изменению на русско-тувинский. Российское цивилизационное влияние в сфере языка увеличивается. Тем не менее также увеличивается влияние тибето-буддийской цивилизационной общности, частью которой считают себя тувинцы-буддисты. Влияние китайской цивилизации минимально, в отличие от тех политических последствий, к которым привела политика китайской империи. Родство с монгольской культурой у тувинцев есть, но оно ограничивается различиями языковых семей народов. Религиозные предпочтения тувинцев в свою очередь отчуждают их от других тюрков мира, большинство из которых приверженцы ислама. Эти и другие факторы также поддерживают чувство особой тувинской этнической идентичности населения.

Die Anwendung von Deep Learning in der manuellen Montage birgt großes Potenzial, Montagezeiten zu reduzieren und Montagefehler zu vermeiden. Indem der Montageablauf mithilfe einer Kamera erfasst und die aufgezeichneten Bilder durch einen Objekterkennungsalgorithmus analysiert werden, lassen sich Position, Lage und Art der montierten Bauteile bestimmen. Daraus lassen sich wiederum Informationen über Arbeitsschritte, Montagefehler oder den aktuellen Zustand des Produkts ableiten, sodass die Mitarbeiter bei der Montage durch entsprechende Anweisungen unterstützt werden können. Es stellt sich jedoch die Frage, inwieweit gegenwärtige Produkte für den Einsatz von Deep Learning geeignet sind. Nur wenn die zu montierenden Bauteile sicher erkannt werden, ist der Einsatz in der manuellen Montage sinnvoll. Bestehende Gestaltungsrichtlinien adressieren diesen Aspekt bislang nicht. Im Forschungsprojekt wurde daher untersucht, welche Eigenschaften Produkte aufweisen sollten, um eine optimale Objekterkennung zu ermöglichen. Dazu wurden Hypothesen zu positiven und negativen Bauteileigenschaften hinsichtlich der Erkennungsgenauigkeit formuliert und in praktischen Versuchen überprüft. Dabei konnte gezeigt werden, dass alle untersuchten Objekte durch den eingesetzten Objekterkennungsalgorithmus sehr gut detektiert werden. Aus den vorliegenden Forschungsergebnissen lassen sich daher keine Einschränkungen in der Produktgestaltung ableiten.
Ausarbeitungsleitfaden für Nutzerstudien zur Evaluation von XR-Interfaces in der Produktentwicklung
Authors: Harlan Jakob , Schleich Benjamin , Wartzack Sandro
Published: September 2021

Technologien der erweiterten Realität (extended reality, XR) finden im gesamten Produktentwicklungsprozess Anwendung. Insbesondere Systeme zur aktiven Erzeugung und Veränderung digitaler Produktdaten bieten noch viel Potential. Die Erforschung und Entwicklung dieser immersiven Interfaces beruht maßgeblich auf der Evaluation durch Nutzerstudien, denn nur so kann die Einsatztauglichkeit der Mensch-Maschine-Schnittstellen seriös beurteilt und verglichen werden. Bei der Konzeptionierung und Durchführung dieser Nutzerstudien gibt es viel zu beachten. In dieser Arbeit wird ein Leitfaden für das Design von Evaluationen von XR Interfaces für die Produktentwicklung präsentiert. Zu Beginn müssen die Fragestellungen festgelegt werden, welche die Studie beantworten soll. Ausgehend von diesen müssen die zu testenden Versuchsbedingungen, die gestellten Aufgaben, die aufgenommen Metriken, die gewählten Probanden und der geplante Ablauf festgelegt werden. Zusätzlich zu der allgemeinen Darlegung wird das Vorgehen anhand eines Fallbeispiels angewandt. Die Gestaltung einer Nutzerstudie zur Evaluation der Usability und Eignung eines neuartigen Virtual Reality Interfaces zur natürlichen Gestaltung von Vorentwürfen wird vorgestellt.

In der vorliegenden Arbeit wird ein Maschinenkonzept präsentiert, welches für die Additive Fertigung von großvolumigen Titanbauteilen speziell entwickelt wurdet. Hierbei wird mit den Direct-Energy_Deposition Verfahren das Bauteil in einer separaten Inertgasatmosphäre erzeugt. Zur Führung der Prozesstechnik soll erstmals ein Roboter verwendet werden, der ebenfalls in dieser Atmosphäre verbaut ist. Dieser ist allerdings schwierigen Bedingungen ausgesetzt, da die Spannungsfestigkeit sowie die Isolationsschwelle in Argon im Vergleich zu Luft drastisch reduziert sind.
İslam İşbirliği Teşkilatı, Sosyal Politikalar ve COVID-19
Authors: Taşçı Faruk
Published: September 2021

Dünyada iki milyara yaklaşan Müslüman nüfusu ve Müslümanları temsilen kurulmuş olan İslam İşbirliği Teşkilatı (İİT) adıyla bir yapılanma bulunmaktadır. Dünyadaki savaşlar, çatışmalar, doğal afetler ve terör olayları çoğunlukla İslam ülkelerinde görülmektedir. Bunların sonucu olarak da İslam ülkelerinde yoksulluk, açlık ve susuzluk başta olmak üzere birçok ekonomik ve sosyal sorunlar baş göstermektedir. Olağanüstü dönemler söz konusu olduğunda (örneğin COVID-19 salgını) da sorunlar daha bariz bir görüntü vermektedir. Bu sorunlarla mücadele kapsamında sosyal politikalar önemli bir enstrümandır. İİT bünyesinde “yardımcı organlar, bağlı organlar, uzmanlaşmış organlar ve daimî komiteler” bulunmaktadır. Bunlar arasında bazıları sosyal politika ile ilişkilidir ve bu ilişkinin somut örneği COVID-19 döneminde belli destekler şeklinde görülebilmektedir. İİT yardımcı organlarından İslam Dayanışma Fonu (ISF) ve Vakfı, uzmanlaşmış organlarından İslam İşbirliği Teşkilatı Ekonomik ve Ticari İşbirliği Daimi Komitesi (İSEDAK) bünyelerinde sosyal politikalar ve COVID-19 adımları söz konusudur. Bu İİT alt organları eliyle yürütülen çalışmalar birbirlerinden kopuktur ve bir standart söz konusu değildir. Dolayısıyla yapılan çalışmalar ve üretilen politikalar nitelikli olmaktan uzaktır. Bu nedenle İİT bünyesinde Sosyal Politikalar Daimî Komitesi adı altında malî yapısı zekâtlarla desteklenen ve veritabanı sistemi güçlü olan bir yapılanma ihdas edilmelidir
АНТИПЛОСКА ЗАДАЧА ДЛЯ ОДНОМІРНОГО П’ЄЗОЕЛЕКТРИЧНОГО КВАЗІКРИСТАЛА З МІЖФАЗНОЮ ТРІЩИНОЮ

Розглянуто тунельну тріщину вздовж межі розділу двох зчеплених одновимірних п’єзоелектричних квазікристалічних півпросторів. Досліджуються провідні електричні умови на берегах тріщини. Вважається, що розташування атомів є періодичним у площині, перпендикулярній фронту тріщини та квазіперіодичним у напрямі фронту, причому остання вісь співпадає з напрямком поляризації матеріалів. Рівномірно розподілені антиплоскі фононні та фазонні зсувні напруження та електричне поле в площині, перпендикулярній фронту тріщини, задані на нескінченності. Побудовані матрично-векторні представлення для фононних та фазонних напружень та електричного поля, а також для похідних від стрибка фононних та фазонних переміщень та електричного зміщення через вектор-функцію, голоморфну у всій комплексній площині, за винятком області тріщин. Задовольняючи з використанням цих представлень умовам на берегах тріщини, формулюється задача лінійного спряження Рімана-Гільберта з відповідними умовами на нескінченності та будується аналітичний розв’язок цієї задачі. Аналізуючи цей розв’язок, отримали аналітичні вирази для фононних та фазоних напружень та стрибків переміщень уздовж межі поділу матеріалів. Показано, що отриманий розв’язок має осцилюючу кореневу сингулярність біля вершин тріщини. Важливо, що ця особливість не призводить до взаємного проникнення берегів тріщини, як у плоскому випадку. До того ж області осцилляції є дуже малими, тому отримані розв’язки є прийнятними для практичного використання. Чисельний аналіз проведений для комбінації різних квазікристалічних з’єднань. Результати отримані для фононних та фазонних компонент пружно-деформівного стану вздовж межі поділу матеріалів і представлені в графічній формі. Зроблені висновки стосовно зміни фононних та фазонних характеристик на межі поділу матеріалів залежно від зовнішніх навантажень та геометричних факторів.
