Authors: YEMENİCİ Aliye İlkay , KARAKAŞ YILDIRIM Özge
Published: December 2023

With online learning being on the agenda again in higher education, university students had different views about the online learning process. While some students evaluated this process as an advantage, others expressed the difficulties of the process. There are reasons, such as students' ability to organize their learning processes and being aware of their capacities under these different views. It was observed that students possessing such skills implement various strategies during the learning process and adapt it to their needs. Self-regulation is a prerequisite for a successful learning process and emphasizes the learner's autonomy and personal preferences. Self-regulation skills have become more noteworthy, especially in the online learning process, where students become passive recipients. While students who have developed self-regulation skills in the online learning process are successful, students who do not have this skill are more disadvantaged. Therefore, in this process, we come across two opposite groups, those who turn online learning into an advantage and those who cannot manage this process. This study aimed to assess the self-regulated learning skills of pre-service Turkish teachers who underwent online learning. This study was designed according to the descriptive survey method and was limited to 1st, 2nd, 3rd, and 4th-grade students in the Department of Turkish Language Teaching. In this study, Online Self-Regulated Learning Scale used developed by Barnard et al. (2008) and adopted into Turkish by Samsa Yetik (2011). The obtained data were analyzed with the IBM SPSS Statistics 25 program. This study found that pre-service teachers' online self-regulation skills differed depending on their previous experience with distance education. Significant differences were found in different sub-dimensions of pre-service teachers' online self-regulation skills based on synchronous or asynchronous attendance in distance education courses.

SİNOP AYANCIK YENİKONAK (OTMANLI) KÖYÜ’NDE GELENEKSEL KIRSAL MİMARİ II
Authors: BAYRAKTAR Mehmet Sami
Published: December 2023

Öz

Sinop İli Ayancık İlçesi’ne bağlı Yenikonak Bucağı’nın Merkez Köyü olan Otmanlı, Ayancık’ın 10 km güneyinde yer alır. Köyde halen konut, ahır - ağıl - samanlık, odunluk, ambar, fırın, çeşme, kuyu, menfez, atölye kümes ve çardak olmak üzere 13 tür geleneksel kırsal yapı bulunmaktadır. Evler ve ev altı kesiminde bulunan ahır - ağıl – samanlıklar ilk makelenin, bunların dışında kalanlar bu çalışmanın konusunu oluşturmaktadır. Yakın bölge ve Karadeniz Bölgesi ağırlıklı bir değerlendirme yapılarak yapı türlerinin karakteristik özellikleri ve geleneksel kırsal mimarideki yerleri konusunda analizler yapılmaya çalışılmıştır. Çalışma, Sinop yöresi geleneksel kırsal mimarisinin belgelenip değerlendirmesine katkı sağlayacaktır. Çalışma alanında bulunan yapıları konu alan bilimsel bir çalışma bulunmamaktadır.

Köy sakinlerinin verdiği bilgilere ve yapıların mimari özelliklerine bakılarak en eski yapıların 17. yüzyıla tarihlediğimiz Meydan Çeşmesi ile 18. yüzyıla tarihlediğimiz 1 Numaralı Fırın olabileceğini düşünmekteyiz. Diğer yapılar 19. yüzyıl ile 20. yüzyıl ortalarına kadar geçen dönemde yapılmış olmalıdır.

Otmanlı Köyü’ndeki geleneksel kırsal yapılar, köy ölçeğinde zamanla biriken halk mimarlığı kültürün bir yansımasıdır. Yapım sistemi bakımından incelenen yapılarda üç ayrı tip ile karşılaşılır. Kâgir yığma, ahşap karkas ve ahşap yığma (çantı). Tipler, çoğu kez aynı yapıda farklı kesimlerde karma şekilde uygulanmıştır. Ancak ahşap yığma ve ahşap karkas, kâgir (Otmanlı’da taş kâgir) sisteme göre çok daha baskındır.

Mekân düzeni bağlamında evlerde olduğu gibi her yapı türünde birbirine benzer bir tipleşmeden söz edilebilir. Ahır – ağıllar – samanlıklar aynı çatı altında bütünleşik karakterli yapılardır. Doğu Karadeniz Bölgesinde serender adıyla bilinen yapıların yalın benzerleri olan ambarlar, direklik ile bunun üstünde yer alan ambar katından oluşan iki katlı yapılardır. İkiz ve tek fırın şeklinde görülen fırınlar; kare mekânlı ve kubbeli ana yapı ile bunun önündeki sundurmadan oluşmaktadır. Çeşmeler; ilki avlu duvarına yaslı, salma lüleli, art arda sıralı uzun yalaklı, diğeri depolu meydan çeşmesi olmak üzere iki tiptir. Etkileyici çatı, kütle, malzeme-teknik ve figürlü bezeme unsurlarıyla köyün en dikkat çeken yapısı olan Meydan Çeşmesi, taşra ölçeğinde özenli ve gösterişli bir örnektir. Demirci atölyesi, kuyu ve menfezler son derece yalın yapılardır.

Otmanlı Köyü geleneksel yapılarının, yapım sistemi, plan, malzeme-teknik, mimari eleman ve süsleme özellikleri, Orta Karadeniz Bölgesinin kırsal yapı karakterini yansıtmaktadır. İncelenen yapıların yakın benzerleri Sinop ve komşu illerde de görülmektedir. “Destek kavila” ayrıntısıyla ayrıca dikkat çeken say taşlı çatı kaplaması, araştırma alanının en özgün mimari unsurudur.

Published: December 2023

Yaklaşık beş asır boyunca Osmanlı Devleti’nin hâkimiyeti altında kalan Balkanlar, Türk halk kültürünün önemli araştırma sahalarından birisidir. Orhan Gazi’nin oğlu Süleyman Paşa’nın 1354 yılında Gelibolu yarımadasını fethetmesiyle beraber Osmanlı Devleti’nin Balkan coğrafyasında hâkimiyeti ve devamında fetihleri başlamıştır. Osmanlı Devleti’nde Balkanlar, Rumeli eyaleti olarak adlandırılmaktadır. Balkanlar, Türkiye’nin bir kısmıyla beraber Bulgaristan, Yunanistan, Hırvatistan, Sırbistan, Bosna Hersek, Makedonya, Arnavutluk, Romanya, Karadağ ve Kosova’yı içine alan önemli bir geçiş güzergâhı ve yerleşim alanıdır. Osmanlı Devleti hâkimiyeti boyunca Balkanlar’ı hemen hemen her alanda etkilemiştir. Fetih sürecinden sonra bölgeye yerleşen Türkler ve Balkan halkları arasında çeşitli etkileşimlerle beraber ortak bir Türk halk kültürü ortaya çıkmıştır. Bu kültürün önemli motiflerinden biri de Alp-Gazi tipinin yansımalarından biri olan “kesik baş” motifidir. Anadolu ve Balkanlar Türk folklorunda “kesik baş” motifini çeşitli türlerde görmek mümkündür. Anadolu’nun ve Balkanlar’ın Türkleştirilmesi ve İslam’ın yayılması amacıyla bölgeye hareket eden alp-erenlerin, savaş esnasında başlarının düşman tarafından kesildiği, başlarını ellerine alıp savaşa devam ettikleri rivayet edilmektedir. Anadolu ve Balkanlar’ın hemen hemen her alanında kesik başlı türbeye rivayetlerde rastlamak mümkündür. Bu çalışmada Anadolu ve Balkan coğrafyasında kesik baş motifine sahip olan evliya ve yatırlar tespit edilmiş, bu evliyaların efsane ve rivayetleri aktarılmıştır. Çalışma alanını Adana, Niğde, Ankara, Hatay, Erzurum, Isparta, Sinop, Elazığ, Konya, Kars, Muğla, Gümülcine (Yunanistan), Mitroviça (Kosova), Prizren (Kosova), İskaça (Romanya) , Adakale (Romanya), Şumnu (Bulgaristan) ve Manastır (Makedonya) şehirlerinde tespit edilen türbeler oluşturmaktadır. Çalışma, literatür taraması ve saha çalışması ile elde edilen bulguların aktarılması olarak sınırlandırılmıştır.
In Search of an Anti-Ageing Drug or the History of Gravidan Therapy in the USSR
Authors: Fando Roman A.
Published: December 2023

The article is devoted to the history of discovery, experimental testing and practical implementation of the gravidan therapy, a method for the treatment of various diseases, introduced by the doctor named A. A. Zamkov. The method was based on the administration of gravidan, a preparation obtained from pregnant women’s urine. The inventor of this miracle drug promulgated a novel medical approach, based on the rehabilitation of the whole organism rather than of its poorly functioning individual organs. According to Zamkov, gravidan contained a complex of various hormones and bioactive substances, invigorated, aided in speedy recovery, and possessed a rejuvenating action. In 1930, after the publication of experiments with gravidan, conducted at the Institute of Experimental Biology, Zamkov was criticized by his scientific colleagues in the Izvestiya newspaper. Soon both he and his wife, the sculptress V. I. Mukhina, were arrested for their attempt to illegally escape abroad, sentenced with seizure of property, and sent into exile to Voronezh. At the time, Zamkov’s influential patients in Moscow joined in a campaign for his return to the capital. In 1932, he created the Laboratory of Urogravidan Therapy that was in 1933 reorganized into a scientific research institute. In 1938, after the Third Moscow Trial, where, inter alia, several physicians were accused of the deaths of a number of prominent figures in the Soviet Union, the USSR People’s Commissariat for Health Care dissolved the Institute of Urogravidan Therapy. The experiments with gravidan were prohibited but Zamkov and, after his death, Mukhina appealed to different authorities to permit production and therapeutic use of gravidan. In the end, it never came into widespread use in medical practice, as a rigorous testing of its effectiveness yielded the results that dispelled the myth of the omnipotent drug.
The Description of Forest Fires in the Works of the Scientists Who Travelled the Russian Empire in the 18th – 19th Centuries
Authors: Tugov Kirill
Published: December 2023

Over many centuries forest fires destroyed forests on a large scale. Historically, Russia possessed and still possesses the largest forest area in the world, twice as large as that of its nearest rival, Brazil. With such vast wooded areas, Russia has encountered the problem of forest fires many a time. Russian archives store numerous documents concerned with this natural occurrence, mostly the accounts and reports prepared by public servants (forest rangers, inspectors, etc.). In the times of the Russian empire, the mentions of forest fires could be also found in the periodicals, forest management manuals prepared by arboriculturists, legal acts, and even in the paintings. The works of the travelers and explorers, based on the expedition materials, notes and observations, hold a special place among the sources concerned with forest fires. The participants in the 18th – 19th century geographic expeditions had themselves witnessed this natural disaster and captured their experiences on paper. With the vast geography of travels and expeditions, the information contained in these works allows to reconstruct the overall picture of the situation with forest fires in the Russian Empire.

Legal analytics in the focus of interdisciplinarity. Review of the XXV International Scientific and Practical Forum “Legaltechnetics” on the topic “Legal analytics: intellectual technologies of legal activity”
Authors: Baranov Vladimir M.
Published: December 2023

The jubilee XXV International Scientific and Practical Forum “Legaltechnetics” has opened a new chapter in the understanding of significant technical and legal phenomena, providing leading representatives of legal science and practice with an opportunity for effective cooperation. For the first time in a quarter of a century, the attention of researchers was drawn to the understanding of legal analytics, doctrinal theoretical and sectoral approaches to its essence, specificity and significance. During the discussion, extraordinary assessments and creative proposals were made, which are of fundamental importance for the long-term construction of a system of knowledge about legal analytics, in relation to legal science, practice and educational activities. Comprehension of a wide range of types and forms of legal analytics associated with modern technologies of doctrinal analysis of legal information, educational technologies, law enforcement activities, criticism of legislation, the problem of legislative imbalance allowed us to come to the conclusion about the integrity and significance of this phenomenon. The actualization of the consideration of doctrinal and practical aspects of legal analytics is based on the permanent growth of the volume and systemic complication of national legislation, the legitimization of the life of society, the demand for interdisciplinary knowledge, the emergence of new socially significant spheres of activity of citizens, the need for lawyers-specialists of a new formation. A deep, multi-level analysis of theoretical, sectoral, applied, technical and legal aspects of legal analytics is designed to create a basic basis for the formation of dominant provisions on the understanding, essence, functioning of this phenomenon, which will not only make it possible to take the next step in the development of technical and legal knowledge, but also significantly enrich the law-making, legal interpretation, legal realization activities with effective tools, it will make positive adjustments to the process of training legal researchers and legal practitioners.

ASYMPTOTIC BEHAVIOR OF Pω(Y0, Y1,±∞)-SOLUTIONS OF THE SECOND ORDER DIFFERENTIAL EQUATIONS WITH THE PRODUCT OF DIFFERENT TYPES OF NONLINEARITIES FROM AN UNKNOWN FUNCTION AND ITS FIRST DERIVATIVE
Authors: Chepok O.
Published: December 2023

The task of establishing the conditions of existence, as well as finding asymptotic images of solutions of differential equations, which contain nonlinearities of various types in the righthand side, is one of the most important tasks of the qualitative theory of differential equations. In this work, second-order differential equations, which contain in the right part the product of a regularly varying nonlinearity from an unknown function and a rapidly varying nonlinearity from the derivative of an unknown function when the corresponding arguments are directed to zero or infinity, are considered. Necessary and sufficient conditions for the existence of slowly varying P!(Y0; Y1;±∞) solutions of such equations have been obtained. Asymptotic representations of such solutions and their first-order derivatives have also been obtained. When additional conditions are imposed on the coefficients of the characteristic equation of the corresponding equivalent system of quasi-linear differential equations, it is established that there is
a one-parameter family of such P!(Y0; Y1;±∞)-solutions to the equation. Similar results were obtained earlier when considering second-order equations, which contain on the right-hand side the product of a rapidly varying function from an unknown function and a properly varying function from the derivative of an unknown function when the arguments go to zero or infinity. Results for the equation, considered in this paper, are new.

Published: December 2023

Aflatoxins are a family of poisonous, mutagenic, and carcinogenic mycotoxins that contaminate a wide range of foods and agricultural goods. Aspergillus species, such as Aspergillus flavus, and Aspergillus parasiticus are the most common producers. Aflatoxin generation can occur at any point of the food chain, including pre-harvest, drying, storage, transit, processing, and handling, if conditions are favourable for fungus to create toxins. It is classified into six main types which are Aflatoxin B1, Aflatoxin B2, Aflatoxin G1, Aflatoxin G2, Aflatoxin M1 and Aflatoxin M2. In Nigeria, Aspergillus species that produces aflatoxin has been isolated from agricultural products such as cereals, spices, locally fermented food, oil-seeds, and animal products. Aflatoxin contamination is high due to poor storage of food crops and lack of awareness of aflatoxins contamination among farmers, marketers and the consumers of these goods. Locally fermented foods such as ogiri, ugba, ogi-baba, and iru have been said to be contaminated by aflatoxin. Preventive measures should be carried out by the policy-making bodies to create awareness and sustain ongoing measures to effectively manage aflatoxin contamination in Nigeria so as to reduce the health risk of aflatoxins on the people and economy of the country.

Published: December 2023

The sharia life insurance program has two ways of managing funds, namely involving a savings element and not involving a savings element. Programs that do not involve a savings element do not have a clear division of tabarru’ funds that must be paid participant so it is the company's job to calculate it . In calculating the percentage of tabarru' funds used method Cost of Insurance (COI) . The COI method is method for calculating tabarru’ funds  with using several parameters, namely mortality tables , investment value , management fees and discount factors . In this research, we will discuss how to obtain tabarru' funds using the 2019 Indonesian mortality table and the 2019 Indonesian mortality table with the Gompertz mortality law, Makeham mortality law and De Moivre mortality law. with method Cost of Insurance . Based on the case illustration, the results show that the tabarru' funds that must be paid by participants are directly proportional to the participant's age, management fees and insurance money, but inversely proportional to the investment value. Tabarru' funds will be greater if using the De Moivre mortality table so this can be a consideration for the company while the Makeham mortality table can be a consideration for participants.
On the Conditions for the Introducing Distance Learning in Russian Universities
Authors: Borovskikh A. V.
Published: December 2023

Modern computer and Internet technologies make it possible not only to transfer educational materials to digital media, but also to implement in a remote format various teaching methods,  diagnostics,  individualization  of  educational  interests  and  trajectories,  and  much  more. In addition, modern technologies in this area allow us to do what was simply impossible within the framework of the conventional education system. But the issue of a reasonable measure of the use of these technologies and the adequate setting and implementation of tasks in this direction requires special work. The article presents the results of this kind of work carried out on the basis of a program-project approach. Although the work was carried out within the framework of the assignment of  the  FEMU  to  classical  universities  for  mathematical  education,  the  specifics  of  universities  and mathematical education were not significant. The assignment was to determine the readiness of the mathematical faculties of universities for the systematic use of distance learning through an expert survey  of  FEMU  members.  The  relevance  of  the  question  of  the  timeliness  of  the  introducing  distance learning in a particular situation, on the one hand, and the problematic nature of this issue, due to the lack of proper systemic, logical grounds for its solution, prompted the author to apply his own method, which is conceptually different from the numerous surveys and “experiences” available in literature. The application of this method (“double inversion of position” or, in other words, “double negation”: intent   – objections  – withdrawal of objections), made it possible to formulate three principal lists. The first contains an explicitly formulated framework in which the introducing distance learning makes sense; the second and third represent the research and development program necessary for the implementation of distance learning. And already on the basis of the first list, related to the current situation, a survey of experts was conducted, which made it possible to formulate the main conclusions on the problem under discussion. The results obtained fix a logical necessity that does not depend on private opinions or specific features of the situation.
Do “Top” Universities the Best in Everything? How the Status and the Size of Russian Universities Correlate to Student Engagement
Authors: Maloshonok N. G.
Published: December 2023

The characteristics of the university that issued the higher education diploma are an important signal for the employer, indicating the quality of the graduate’s training. However, it remains unknown to what extent top Russian universities really differ in the quality of the educational process from other universities, and do not simply use their ability to admit the most talented and motivated students. This paper attempts to answer this question using student engagement indicators, which are considered worldwide as a valid tool for assessing the quality of higher education. The article aims to examine the relationship between student engagement and two institutional characteristics of universities (a special status and the size of the university) by employing survey data on 16,143 students studying at 401 Russian universities. The results demonstrate that students studying at federal, national research and flagship universities have comparatively lower class engagement and social engagement compared to students from universities without special status. In addition, students at institutions with a size between 1,000 and 3,500 students were the most engaged in class activities and, at the same time, disengaged, while a size of less than 1,000 students  was  negatively  associated  with  disengagement.  The  results  obtained,  on  the  one  hand, require  further  research  into  the  relationship  between  institutional  characteristics  and  student engagement. On the other hand, they indicate the need to increase the weight of indicators of the quality  of  the  educational  process  in  universities  in  government  excellence  initiatives  aimed  at identifying leading universities and supporting them, as well as the importance of developing valid indicators of the quality of the educational process that can be used as a criterion in such government competitions.
