    Clinical Development of Quinone-Based Drugs
    (Elsevier, 2024) Altuner, E.E.; Issa, G.; Ozalp, V.C.; Aldemir, O.; Torlak, Y.; Dar, U.A.
    This chapter provides a detailed explanation of the clinical investigations, pharmacological effects, and characteristics of quinone and quinone derivatives, along with references to pertinent sources. Although quinones have an oxygen group in their structure, they are quickly oxidized and interact with reactive oxygen species. This demonstrates how quinones work as drugs. Quinones and their derivatives are used as medications to treat a wide range of diseases, including cancer, lung, kidney, brain, and tumor disorders. Each of the following has effects on a different area of health; lapochols, anthraquinones, naphthoquinone and its derivatives, and other wide range of quinone derivatives are thoroughly explored in this chapter. © 2025 Elsevier Inc.

    Comparative Analysis Of Patch Antennas With Rectangular Slots For Laminate And Wearable Materials At 5g Networks
    (Institute of Electrical and Electronics Engineers Inc., 2024) Hakanoglu, B.G.; Agaya, E.; Gulmez, G.; Yalinsu, S.
    In this study, new multi-band patch antenna design models are proposed for use in 5G networks. The purpose of the designs is to open rectangular slots on rectangular shaped patch antennas and bring them to the desired operating conditions with parametric analyzes. The designs were carried out by following the same procedure steps using five different dielectric laminate substrate materials, such as RO3003, RT6006, FR4, RO3203, RO6010, and one denim fabric base material. The antennas were compared in terms of return loss, gain and radiation characteristics. Except for the antenna designed with RO3203 at certain values of rectangular slots, radiation at multiple frequencies was obtained at 5G frequencies. With the proposed method, improvement was observed for return loss and bandwidth characteristics in the RO3203 based antenna. This study will be a resource for antenna researchers by revealing the responses of different substrate materials to the same design method for 5G bands in patch antennas. © 2024 IEEE.

    Need for a Software Development Methodology for Research-Based Software Projects
    (Institute of Electrical and Electronics Engineers Inc., 2018) Cereci,I.; Karakaya,Z.
    Software development is mostly carried by a group of individuals. Software development methodologies are heavily utilized to organize these individuals and keep track of the entire software development process. Although previously proposed software development methodologies meet the needs of the industry and the firms, they are not usually suitable for research-based software projects that are carried by universities and individual researchers. In this paper, we aim to show the necessity of a new software development methodology for research-based problems carried by universities. The literature review will show the differences between industry and university software projects from certain aspects. These findings will be supported by the authors own research on the area. This qualitative research involves collecting data through interviews and applying Grounded Theory to better understand the development process. © 2018 IEEE.

    Characterization of Satellite Transponder Impairments Based on Simulations with Test Data
    (Ieee, 2015) Ulubey, Orhan; Gulgonul, Senol; Kara, Ali
    A satellite transponder simulator based on actual test data of TURKSAT 3A satellite has been developed to analyze degradation in multicarrier scenarios. Communication impairment sources through a transponder are explained in conjunction with a methodology defined to characterize total degradation resulting from them. Several transponder utilization scenarios are studied with respect to total degradation and optimum operation conditions are demonstrated.

    Supply chain resilience in the tourism and hospitality industry: A comprehensive examination of driving and restraining forces
    (Elsevier Sci Ltd, 2024) Erol, Ismail; Oztel, Ahmet; Dogru, Tarik; Peker, Iskender; Neuhofer, Irem Onder; Benli, Tolga
    Supply chain disruptions and a lack of resilient supply chains have adverse impact on the global economy. Particularly, complex nature of the tourism and hospitality industry makes it even more susceptible to failure when supply chain resiliency is rather low or does not exist. However, despite its significance, a comprehensive and systematic examination of building resilience in tourism and hospitality supply chains (THSCs) is lacking in the extant literature. The purpose of this study is to develop a comprehensive framework that outlines the driving and restraining forces for building resilient THSCs. The decision framework proposed in this study integrates rough interval valued neutrosophic (RIVN) force field theory of change with RIVN-ISM-MICMAC methodology. The results showed that the restraining forces, such as lack of effective regulations and incentives and effective organizational and supply chain policies are the primary factors that constrain improving resilience in THSCs. Theoretical and practical implications are discussed.

    HOW TO WRITE POETICALLY
    (Iated-int Assoc Technology Education A& development, 2012) Tekin, Kugu; Selimoglu, Zeynep Rana
    The importance of the role of writing in second language acquisition is indisputable. Compared to other skills, such as reading, listening and speaking, writing has a unique place, for it is a creative and productive stage of second language learning. It has been observed that almost every student has difficulty in writing. Students struggle to write even a solitary sentence let alone a well organized, coherent and accurate essay, which is a prerequisite for English Preparatory School students and for freshman students of English Language and Literature departments. The aim of this paper is to show how supposedly "boring" writing courses can be made attractive, enjoyable and at the same time productive to students. To this end, we provide our students with an atmosphere wherein creativity, enjoyment and above all, learning can take place. Our chosen medium in the construction of such a learning environment is poetry. The paper consists of two sections: the first is the theory section, which is about the function of literature. This section also includes a number of poetry definitions and the advantages of using poetry in writing courses. The second section focuses on practical activities to demonstrate how poetry can be applied to improve students' writing skills. The second section proceeds in three subsections entitled "pre-writing", "writing" and "post-writing". The overall aim of these activities is to integrate the two receptive language skills, reading and listening, and the two productive skills, writing and speaking. In conclusion, this paper is an attempt to turn a negatively perceived writing class into a student-friendly activity.

    The Dark Side of Proactive Behaviors and Blind Spot Management
    (Springer Science+Business Media, 2025) Uwizeye, J.; Tuzlukaya, S.E.; Asbas, C.
    Proactive behavior, which should be anticipatory and agentic, can be defined as actions focused on certain behaviors aimed at improving job performance, career success, and employee well-being. Even if organizational citizenship behaviors have been frequently characterized as proactive behaviors, this is not true under every condition, as they may be either reactive or passive. Although proactive behavior among employees has been widely studied because of the importance that organizations place on improving performance and effectiveness, the potential and possible negative outcomes of such behavior have often been ignored. Examining and discovering the potential negative implications of proactive behaviors and formulating strategies to manage blind spots are vital for developing a general understanding of proactive behaviors for both employees and firms. The intention of this study is to conduct a literature review on proactive behaviors by focusing on the dark side and blind spots of proactive behaviors. This chapter also explains various forms of proactive behaviors and theories that can effectively describe the negative outcomes of such behaviors and discusses the detrimental effects of proactive behaviors on both employees and organizations. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
