Authors:Pınar KORKMAZ Abstract: Financial failure has been seen as the most critical threat to companies, investors and lenders for many years. With the impact of globalization in recent years, as well as the reflection of technological advances and financial conditions, it is seen that national and international sectors are rapidly differentiating and progressing. This difference and progress brings to the forefront the prediction of financial failures, mostly for companies. In this study, the concept of financial failure, types of financial failure, measures that can be taken to prevent financial failure, methods used to predict financial failure, financial technology, financial technology process, financial technology players and Borsa Istanbul concepts are explained conceptually.In the study, it is aimed to predict the failures of companies with financial data using logistic regression method. Ratios were created by collecting data from 27 technology companies traded in Borsa Istanbul. Unsuccessful companies were identified with 2021 data and financial data for the last three years. The data of the companies were primarily created according to 3-month periods, but as only the annual data of some companies for the years 2018 and 2019 could be accessed, it was decided to use annual data. The ratios determined for the years 2018, 2019 and 2020 were used as independent variables. When the ratios with missing data were removed, analysis was performed with 60 different ratios. Fixed Assets/Tangible Equity, Net Debt/EBITDA(Annual) and Total Debt/Equity ratios in predicting the financial failure of companies 3 years in advance, EBITDA/Growth (Annual) and Short Term Debt/Total Debt ratios in predicting 2 years in advance and 1 year in advance, Return on Equity/ROE and Short Term Debt/Growth ratios were found to be successful..

Authors:Behzat Gökçen DEMİR; Ali Koray ÖZDOĞAN, Akın AKBULUT Abstract: Mining has been an important acvitiy field for the development of humanity throughout the historical process from past to present. Mining activities carried out in Anatolian lands have a unique and special place in history. Today, mines and mining are still at the forefront in many areas of our lives. Although feldspar minerals are one of the most abundant mineral groups in the earth’s crust, the number of source rocks in which feldspar is obtained/produced commercially/economically is limited. Türkiye’s increasing export volume in recent years have made positive contributions to the export of the mining sector. This positive contribution can be considered as one of the factors that increase the export figures of feldspar mining, which is one of the important sub-branches of mining, in terms of quantity and value. Türkiye has taken the first place in world feldspar production in recent years. The provinces where feldspar minerals are economically important reserve regions and mining fields are mainly Aydın, Muğla and Bilecik. In this study, it is aimed to make a general assessment of feldspar mining and to provide information on the basic points. PubDate: Sat, 31 Dec 2022 00:00:00 +030
Authors:Ender ÇELİK; Vedat SAVAŞ Abstract: The aim of this study is to determine the optimal shape and clearance of the web openings in order to both increase the carrying capacity and decrease the weight of classic perforated beams by using evolutionary topological optimization technique. The effects of the optimal shape and web openings has been obtained by the application of the evolutionary topological optimization through finite elements method, and then the obtained optimal beam has been compared with widely used perforated beams in the market by using stress and displacement analysis. The designed beam was seemed to have more advantages then the widely used ones in industry with a less weight and higher carrying capacity. With the topology optimization, the usual classic perforated beams’ geometry has been changed and stiffness was improved. PubDate: Sat, 31 Dec 2022 00:00:00 +030
Authors:Kimia BELADİ Abstract: Nowadays, reducing energy consumption and coexistence with natural and climatic conditions in the region has become one of the most prominent architectural goals. As a result of the growing population and crisis created by rising energy demand, managing energy consumption patterns has become an essential component of sustainability. By recognizing Iran’s culture, customs, traditions, and climates, traditional Iranian architectures designed and built the constructions with the least use of non-renewable energy. Besides, simple and logical methods had provided the most use of renewable energy. As a result, this study explores the optimization of energy consumption in the housing sector through current native pattern designing in hot and dry regions, with a specific emphasis on the relevance of energy savings. The case study of this research is Lariha house. Its Building design style will examine such as wall thickness, placement, the height of internal structures, etc, and the elements used plants, porches, wind flow, etc., which directly influences optimizing energy usage.

Authors:Ramazan KAZAN Abstract: Blockchain technology is attracting attention from academies, industries, governments all over the world. Expectations of increased potential have led to extensive exploration of the use of this technology in various application platforms. Today, blockchain is considered to be a technological breakthrough that touches all areas of social life, and is expected to lead to very significant changes, especially in a few application areas. In the study; A certification diploma verification system has been developed using the decentralized, open-source blockchain platform. Thanks to the integration of blockchain technology with the document verification system, the centrality in the control mechanism can be eliminated and user initiative can be eliminated. In addition, the task of verifying documents in existing systems is a time-consuming process. Treatment can take up to several months, depending on the provider's response. Thanks to the blockchain, employers or institutions that want to verify documents will be able to perform their transactions without spending time and money. PubDate: Sat, 31 Dec 2022 00:00:00 +030
Authors:Adil MASSMAR Abstract: Pharmaceutical systems are care settings characterized by the wide range of activities and scenarios with which they would be challenged. This causes interactions that result in unexpected scenarios associated with a variety of dangers such as variations in demand, risks associated with supplier relationships, and so on…. As a result, risk management appears to be a major issue for decision-makers. Today supply chain management needs to be dynamic and responsive to create added value, and mitigates these risks by using flexibility strategies to respond to change while remaining competitive. The goal of this research is to look into the supply and demand strategies used by pharmaceutical companies to respond to disruptions and avoid medicine interruptions for consumers. In this thesis the supply chain risk management strategies are basically connected to an empirical study done in 32 Moroccan pharmaceutical enterprises. Following that, the participants’ responses were based on a questionnaire structured through the literature seeks to bring more detailed information about these strategies. Accordingly, the results showed that Moroccan pharmaceutical firms focus on some crucial activities such as supplier selection, flexible control, supplier control, vendor verification, and inventory management to account for supply and demand risk.Empirical studies in the field of pharmaceutical risk management are rare. Thus, the goal of this work is address the scarcity of empirical studies in this field by outlining several key risk management strategies used by pharmaceutical supply chain laboratories in the context of Morocco which are putting more resources into these vital strategies. Most of the supply and demand techniques of these firms are found to be proactive . PubDate: Sat, 31 Dec 2022 00:00:00 +030
Authors:Özgür KALENDER; Bahadır UÇAN Abstract: Especially with the increasingly interactive media productions in recent years, the use of the term interaction has increased to a great extent. In the light of these developments, an increase is observed in the use of terms such as multimedia, hypermedia, combined media, information highway, and digitalization. All these terms can be examined as the structure of an interactive media design produced, as well as under the interaction of design with the user. With the CD-ROM technology developed in the early 1980s, the designers, who had the opportunity to transfer data to more areas, increased their full-motion video game production that transformed passive viewers into active users. Developed by Nintendo in 1974, Wild Gunman is the first example of the development of such games. In particular, full-motion video games that adopt the concept of choose your own adventure, create a personal experience thanks to the one-to-one interaction with the users. This publication was created by Özgür Kalender, prepared under the consultancy of Assoc. Dr. Bahadır Uçan. It is derived from his thesis titled “Study of Full Motion Video Games: User Interface and Narrative Examples”, Yıldız Technical University Interactive Media Design Master's Program and it is designed to provide a general explanation of the interaction elements of full-motion video games that interact with the user and have the feature of choose your own adventure.

Authors:Yasemin Hazel YILDIRIM; Ali Osman KURUŞCU Abstract: Historical buildings, which have been exposed to natural and artificial factors for centuries, cause many damages over time due to these effects. These damages; it changes according to the place where it occurs, its form and the general characteristics of the building and causes damage, collapse and destruction of the structures. Especially in the protection and intervention phase, these damage forms need to be interpreted correctly. Unconscious and incorrect repair and strengthening methods can cause serious problems in buildings. Therefore, within the scope of this study, the repair and improvement methods applied in historical buildings were examined and in this context, the mistakes made in the repair and strengthening methods applied in exemplary historical buildings from the world were explained. In this research, it is aimed to show that the causes of damage should be determined while intervening damage, and should be done many analyzes, experiments and tests that the structural reinforcement and repair methods preferred by many disciplines working together.

Authors:Sohayla ALY Abstract: Sentiment analysis is considered the process to extract the overall expression, opinions, or feelings from reviews about something such as products, services, or movies. Pre-processing is considered a crucial phase in sentiment analysis for text mining because it allows us to analyze the reviews according to their intended meaning by removing all of the appendages which are the words that do not affect the semantics of sentences. And therefore, the number of features will decrease and thus accuracy will increase. Accordingly, we have decided to evaluate our experiment in identifying the best influencing technique of pre-processing for several features by making a comparison between the features and by combining them together to reach the best result based on the feature number for each pre-processing technique and classification accuracy. this comparison was done by using three algorithms for classification SVM, NB, and DT after applying tools for feature selection and feature extraction with three techniques for tokenization. We concluded that there are some of these techniques that have a negative effect like lemmatization and the part of them is not due to any difference, other, which a little part, have an effect PubDate: Sat, 31 Dec 2022 00:00:00 +030
