Sadik, Ramin
During World War I, fierce clashes took place between the Ottomans and Russia on the Caucasus Front. The Ottoman state, whose army in the region was not fully prepared for the war, was heavily wounded in the Sarikamis Operation and then could not adequately defend against Russian attacks. Consequently, the conflicts in the east ended in defeat for the Ottomans. Especially after the Russians took control of Erzurum in 1916, they intensified their military operations directly to the west, south and east coast of the Black Sea. Having taken Erzurum, the Russian Caucasus Army command devised a plan to capture Trabzon, a strategically located city that played a key role in equipping the Ottoman III Army in the east. In fact, if the Russian army captured Trabzon, it would be able to supply its troops in the east with arms, ammunition and food more quickly. In this sense, Trabzon was very important for the Russians. Consequently, after the occupation of Erzurum, the Russian armies moved towards Bayburt and Gumushhane via Askale on the one hand, and towards Trabzon with both navy and land forces in the eastern Black Sea region on the other. In late March 1916, attacks on Trabzon intensified, culminating in the occupation of the city on April 18, 1916. In this study, the process of the occupation of Trabzon is written in the context of Russian sources. The main difference of this study from the previous ones is that it was prepared by analyzing the information provided in the Russian archival documents and press of the period, as well as in Russian-language sources in general. Therefore, the archival records of the correspondence of Russian commanders with their headquarters during the occupation of Trabzon and the day-to-day news of newspapers and magazines about the war constituted the basis of the originality of the article.

Dayi, Rumeysa bakir
While Nietzsche is a 19th century German philosopher, man of letters, musician, linguist and cultural critic, one of the most well-known names in the field of modern Arabic literature is the man of letters, painter, poet and philosopher Cibran Khalil Cibran. Bringing literature and philosophy together, Cibrans writing life is divided into three phases. The first period in which he deals with social issues is the second stage, which includes doubt and rebellion, and the third stage, where he reaches the maturation of the mind and moves to more peaceful thoughts. In the second phase, when Cibran adopted Nietzsche and identified himself with his thoughts, he wrote his work called The Prophet. The work called The Prophet is very similar to Zarathustra, Thus Spoke, in terms of subject and thought. In study, the German philosopher Friedrich Wilhelm Nietzsche, who wrote critical articles on religion, morality, culture, philosophy and science, and his work titled Also Sprach Zarathustra, titled Thus Spoke Zarathustra, and Cibran Khalil Cibran, the most important face of Immigrant literature, which started a great era in modern Arabic literature. Cibrans Ermis, original printed as The Prophet, will be compared in terms of the aforementioned similarities and differences.

Azili, Kenan
As many world languages, Turkic also has simple suffixes in terms of structure, as well as complex suffixes with controversial origins. Although some of these suffixes have been systematized and bound to certain rules, the emergence of some suffixes still remains a mystery. Old Uyghur, which is one of the historical periods of the Turkic language, has such an undeciphered suffix. The compound suffix of +DXrtI has been evaluated by some researchers to date; however, no definite conclusion has been reached regarding its origin and function. For this purpose, various structures in Altaic languages will be examined and a connection will be made between this suffix and the 'extraordinary' examples seen in Old Uyghur.

Arí, Yilmaz Onur; Izgí, Fatma
Bosnia and Herzegovina's transition from socialism to capitalism has led to fundamental changes in the country's economic structure, with unemployment, FDI, economic growth, and information technologies becoming critical factors in this process. Information and Communication Technology (ICT) and Foreign Direct Investment (FDI) can promote economic growth and generate employment, helping to tackle unemployment through various channels. Bosnia and Herzegovina has been facing long-term unemployment for years. Thus, this study uses an Autoregressive Distributed Lag (ARDL) bounds testing approach and structural break technique to explore the impact of FDI, ICT, and growth on unemployment in Bosnia and Herzegovina for the period 1997-2022. The research findings indicate that FDI has a negative impact on unemployment in the long run. On the other hand, ICT has a positive impact on unemployment in the long run. Moreover, empirical findings demonstrated that there is a negative and significant relationship between growth and unemployment in the long run. This implies the validity of Okun's Law for Bosnia and Herzegovina. Furthermore, the study brings forth a crucial insight that the impacts of FDI on unemployment are not uniform and differ significantly based on the type of FDI inflows.

Güven, Ahmet Zeki; Yilmaz Karaca, Meryem; Banaz, Emrullah
The present study explores Turkish learners' approaches toward digital writing and how digital writing contributes to their language learning. For this purpose, we recruited 21 international students from 16 countries, 10 males and 11 females, who attended B2C1 -level Turkish language classes at the Akdeniz University Turkish Language Teaching Center in the 2021-2022 academic year. We recorded and transcribed the data collected through face-to-face interviews with a semi -structured interview form consisting of 6 questions. The data were then coded to generate themes, and the findings were grounded on the interpretation of these themes. Accordingly, the results uncovered that all participants engage in digital writing and mostly utilize WhatsApp, Instagram, Telegram, YouTube, and Twitter as digital writing platforms. Moreover, they were found to usually mind proper spelling and punctuation and tend to use the T9 typing system in digital writing in Turkish. We also discovered that participants find auto -correction useful and sometimes misspell vowels, consonants, and longer words/consecutive suffixes due to differences between spoken and written languages. They particularly thought that digital writing contribute to their learning of Turkish. Overall, we comprehensively discussed the findings and raised some recommendations for future research.

The subject of the research was determined as the place and importance of folk dances in Turkish folklore. The aim of the research is to reveal the place and importance of folk dances and music, which are among the phenomena in Turkish folklore, in Turkish folklore. The method of the research is a descriptive study and the current situation was tried to be revealed by examining the scientific sources obtained through the scanning method. The importance of the research is considered important in terms of revealing the place and importance of folk dances and music, which are an important element of Turkish culture and civilization, in folklore. Folklore and culture are related to each other due to their similar nature. It constitutes traditional products (customs, traditions, language, religion, oral and written and architectural art, sports, literature, etc.) belonging to the national and spiritual elements of a society with a cultural history in a certain period. Folklore, on the other hand, is a science that researches, examines and compiles the cultural products produced in the past by delving into unknown historical depths to which society and which period they belong. Folk dances are also a culture-art phenomenon within folklore. Folk dances, which are among the Turkish folkloric elements, carry the cultural phenomena that the Turkish nation has revealed throughout its five thousand years of life, from its emergence on the stage of history to the present day. Turks have existed in many different geographies in the world and as a result, Turkish folklore has revealed the products of a very rich cultural accumulation. Among these products, folk dances have an important place. Folk dances are distributed in different types according to regions in Turkey. This distribution has brought great diversity to folk dances and contributed to Turkish folklore. As a result, folk dances, as an intangible cultural heritage, contribute to Turkish folklore by showing their presence in Turkey's geography with different types and diversity qualities, especially the rich accumulation that the Turks have acquired from the time period when they appeared on the stage of history until today. In this direction, the research tried to reveal the place and importance of folk dances in Turkish folklore, taking into account the contributions of our folk dances in Turkish folklore.

There has been an increasing interest in biocatalysts over the past few decades in order to obtain high efficiency, high yield, and environmentally benign procedures aiming at the manufacture of pharmacologically relevant chemicals. Lactic Acid Bacteria (LAB), a microbial group, can be employed as biocatalysts while performing asymmetric reduction of prochiral ketones. In this study, Leuconostoc mesenteroides N6 was used for the asymmetric bioreduction 1-indanone. And then, a novel and innovative face-centered design-based multi-objective optimization model was used to optimize experimental conditions. Also, the experimental design factors were defined as agitation speed, incubation period, pH, and temperature for optimization to acquire the maximum enantiomeric excess (ee) and conversion rate (cr) values. When using the face-centered design-based multi-objective optimization model, the optimum culture conditions corresponded to 96.34 and 99.42%, ee and cr responses, respectively, were pH = 5.87, incubation temperature = 35 °C, incubation period = 50.88 h, and agitation speed = 152.60 rpm. Notably, the validation experiment under the optimum model conditions confirmed the model results. This study demonstrated the importance of the optimization and the efficiency of the face-centered design-based multi-objective model.

Turan, Muhittin; Adiyaman, Gokhan
A new type of functionally graded material (FGM) with material properties varying in two or three directions is needed to obtain materials with better mechanical properties and high-temperature resistance for use in the military, aerospace, automotive, and engineering structures. Considering the porosity that occurs during the production of these materials, it has become necessary to examine the free vibration and buckling behaviors. Therefore, this study investigated free vibration and buckling analysis of porous two-directional functionally graded (2D FG) beams subject to various boundary conditions. A high-order finite element based on parabolic shear deformation theory (PSDT) is proposed to solve this problem. Three types of porosity distributions were used in the study (FGP-1, FGP-2, and FGP-3). The governing equations are derived from Lagrange’s principle. The material change in the beam volume in both directions is defined by a power-law rule. The dimensionless fundamental frequencies and critical buckling loads are obtained for various boundary conditions, gradation exponents (px, pz), porosity coefficient (e), porosity distribution, and slenderness (L/h). The numerical results obtained with the proposed higher-order finite element are compatible with the literature.

Yildiz, Aysun Yurdunuseven; Öztekin, Sebahat
Today, the most preferred materials used in food packaging are non-degradable petroleum-based plastic polymer materials due to their high barrier and mechanical properties. These polymer materials are not sustainable due to limited petroleum resources. These non-biodegradable materials pose a serious problem for the environment and affect the entire ecosystem. In recent years, as an alternative to traditional materials for food packaging, the demand for the development of environmentally friendly packaging materials has increased in order to reduce and/or limit the negative impact on the environment. The increasing interest in environmental issues and human health has led to the investigation of possible matrices for bio-packaging in the field of food packaging. In this context, there is an increasing interest in the utilization of fruit and vegetable wastes such as peels, pips, seeds, and leaves. Fruit and vegetables are among the most widely consumed products worldwide, and their waste is the most abundant food waste. These wastes, which are released after fruit and vegetable processing and contain valuable components, can cause environmental pollution if not managed properly. The management of this large amount of waste is difficult, and it is usually either disposed of in water sources and open storage areas or used as feed or compost. However, these wastes have the potential to be used as raw materials for the development of value-added products. Due to their abundant availability and biodegradability, these wastes can solve the major problems associated with conventional plastics used for food packaging and improve sustainable development and life cycles. A more sustainable and greener world can be targeted with these biodegradable materials. This chapter focuses on the conversion of fruit and vegetable waste into environmentally friendly food packaging systems. The chapter emphasizes the advantages and disadvantages of using fruit and vegetable waste as food packaging material and its potential applications. In this context, all mentioned aspects have been comprehensively reviewed, taking into account the literature reported in the last five years. Before processing fruit and vegetable wastes into packaging materials, some steps, such as extraction and purification, are necessary. Materials derived from these wastes have the potential to be used in food packaging with various advantages, such as non-toxicity, biodegradability, and abundant availability. However, there is also a great debate about the applications of these food packaging materials. Further research is needed to improve the barrier and mechanical properties of packaging materials derived from fruit and vegetable waste. Most bioplastics do not meet the basic requirements of food packaging in terms of barrier and mechanical properties, and various modifications are needed to improve their properties. Therefore, future studies should focus on the necessary research to improve the barrier and mechanical properties of materials derived from these wastes. Finally, the legal framework for the large-scale use of these biomaterials derived from fruit and vegetable wastes in food packaging is insufficient, and this may affect the commercialization and consumer acceptance of the products.

Carbas, Serdar; Artar, Musa
In this paper, a creative design methodology is exhibited to attain seismic design optimization of steel frames that are equipped with double diagonal braces on which Pall friction dampers (PFDs) are mounted. The PFDs supply highest seismic energy dissipation to a structure for restricting destructive structural responds. Hence, the PFDs provide elastic movement to the steel frames to avoid the damaging consequence of an earthquake. To achieve this, the seismic energy dissipation over PFDs mounted on double diagonal brace members are tried to be maximized in this study. The Kobe earthquake record is used for conducting nonlinear dynamic time-history analyses to acquire structural responses of the steel frames. The Jaya algorithm (JA) that is a gradient- and parameter-free metaheuristic optimization technique is selected as an optimizer. The design algorithm encoded in MATLAB is integrated with SAP2000 structural analysis program through inbuilt open application programming interface (OAPI) functions to achieve simultaneous structural seismic responses. In proposed design methodology, firstly the optimal designs of steel frame structures without implementing double diagonal friction dampers are accomplished under effect of seismic loading exposed to structural design constraints of stress, displacement, drift, and geometric taken from AISC-ASD structural specifications. Then, the double diagonal friction dampers are implemented in the optimally sized frames to determine optimum yield strengths which are frictional slip loads. Hereby, the JA makes certain the dissipated seismic energy as maximum by checking the yield strength between the frame stories. In the end, it is verified that the PFD mounted double diagonal friction dampers provide maximum seismic energy dissipation throughout the steel frame structures for optimal sizing.
