Investing in a machinery park is a crucial decision process for businesses, as it requires significant resources and subsequently affects all production activities. Proper utilization of machinery improves production processes, increases efficiency and reliability, and enables flexibility and effectiveness in manufacturing. This process, which requires experience and knowledge, encompasses multiple criteria and involves various departments. This research aims to solve the printing machine selection problem using fuzzy multi-criteria decision-making methods, for an investment in a newspaper printing facility. Fuzzy AHP is employed to determine the importance weights of criteria, while fuzzy EDAS is used to evaluate alternatives based on criteria. The criteria considered in the study, based on expert opinions and literature review, are as follows: cost, efficiency, and flexibility. Four different printing machines that are deemed suitable for the process and feasible for purchase are selected as machine alternatives. The decision-making group consists of the printing manager, business development manager, technical manager, and electrical and mechanical maintenance engineers. Sensitivity analysis results conducted to assess the impact of linguistic expression variations on the analysis outcomes demonstrate a high level of validity in the research. [ABSTRACT FROM AUTHOR]

The aim of this research is to investigate the musical interest level of the students taking education in varied Departments of the Universities. General survey model has been used as research design. The study group of the research consists of 105 (61 female, 44 male) spring term students taking education in a state university taking place in Western Black Sea region. ‘Interest Level Scale’ developed by Okay, Gençel Ataman and Kırtak Ad was used in order to evaluate the relevance level of students taking education in varied departments. The obtained data was analysed via Mann-Whitney U and Kruskal Wallis H tests. Research findings showed that there is statistical significance among the musical interest level of the students taking education in medical, mechanical engineering and department of Turkish language and literature students. Further, while there is no statistical significance among the students in terms of age and grade, there is a statistical significance in terms of gender and high school types. [ABSTRACT FROM AUTHOR]

Islamic civilizations paid a great importance to mechanical engineering applications in the field of military technology. Pre-Anatolian and especially Ottoman pamphlets contain a rich collection of archery terminology. This issue sank into oblivion, however, during the Medieval Anatolian era, despite the array of publications in the anterior and posterior periods. On this account, the narrative and drawings of medieval engineers such as İbn Erenboğa and Tarsusî have survived. Through these enginerring treatises, we became accustomed to the terminoloy of throwing machine such as arrade, carh, zemberek. In İbn Bîbî's Selcukname, arrade, carh and zemberek are often mentioned. The Carh known as crossbow in western literature and kavs-al rijl in Arab literature, is a weapon belonging to the category of the sort of swaddle bow. It was used as a synonym to zemberek. In the arrow treatises of the Mamluk period used by the cavalry, it was called kavs-ar-rikab. However, it seems that this roller (capstan) type of the carh is not suitable for cavalry. In actual fact, the carh, as a type of crossbow, is a different weapon from the mounted 'tension spring' one. Arrade is a type of catapult weapon that usually throws stone balls. Arrade that could throw stones over a long distance was of different types as attested by the expression Mancınık-ı endâz, Arrâde-i endâz or Neft-i endâz found in the Mübareksah's military treatise. The information we have about the barbs of these machines is very limited. Especially for the Islamic period, this issue remains completely unknown. It is understood that some of the barbs (temren) uncovered by excavations dating from the period of Anatolian Seljuks belong to these weapons. This paper will discuss the specificities of these weapon and of their discovered in the medieval ruins as Samsat and Kubad-abad. [ABSTRACT FROM AUTHOR]
