Book Part Gender Representation in New Media Through Global Calendar Photographs(IGI Global, 2021) Karabacak,Z.I.; Özgen,Ö.New media that enables access to more people is a preferred platform by Lavazza for bringing together consumers from all around the world within the framework of coffee culture by means of photography. Lavazza calendar photos (1993-2012) have been analysed using Dyer's non-verbal communication means and lines of appeal under the following headings: "Sexually Highlighted Female Body in Lavazza Calendar Photos, ″ "Different Sexual Orientations as Secondary Emphasis of Lavazza Calendar Photos, ″ "Idealized Body Look of Models of Lavazza Calendars, ″ "Roles of Women and Men in Family in Lavazza Calendar Photos, ″ "Queens and Superheroines in Lavazza Calendars, ″ "Widespread Representation of White Race in Lavazza Calendar Photos, ″ "Italian Cities and Italian Local and National Items in Lavazza Calendars, ″ "Signs of Different Geography, Culture and Life Styles in Lavazza Calendar Photos, ″ and "Lines of Appeal in Lavazza Calendar Photos.'' According to the findings, both non-verbal means of communication in terms of gender and lines of appeal in Lavazza calendar photos in new media have changed over the years. © 2021, IGI Global.Article Citation - WoS: 6Citation - Scopus: 6Modification of Poly(methyl Methacrylate) Surfaces With Oxygen, Nitrogen and Argon Plasma(Amer Scientific Publishers, 2014-06-01) Ozgen, Ozge; Özgen, Özge; Hasirci, Nesrin; Özgen, Özge; Physics Group; Physics GroupPoly(methyl methacrylate) (PMMA) is a strong and lightweight material used in wide range of areas changing from lenses to medical and dental devices. In this study, PMMA samples were modified by oxygen, nitrogen and argon plasma with application of 100 watts 13.56 MHz radio frequency (RF) discharge for different periods (5 min, 15 min and 30 min) and the effects of plasma parameters on surface chemistry, hydrophilicity, surface free energy and topography were examined. XPS analysis showed formation of free carbonyl and carbonate groups by oxygen plasma, carboxylic acid and free carbonyl by argon plasma, and imine, primary amine, amide and nitrozo functional groups by nitrogen plasma treatments. For all cases plasma treatment created more hydrophilic surfaces with lower water contact angles than that of pristine PMMA. Also, plasma caused an increase in the surface free energy and its' polar components determined by Geometric Mean, Harmonic Mean, and Acid-Base approaches. AFM results showed increasing roughness parallel to the duration of plasma. As a result, each plasma treatment caused different functionalities and physical topographies on PMMA surfaces and different functionalities can be used for further developments such as binding specific active molecules to design biosensors or medical devices.Book Part Gender Representation in New Media Through Global Calendar Photographs(IGI Global, 2022) Karabacak,Z.I.; Özgen,O.New media that enables access to more people is a preferred platform by Lavazza for bringing together consumers from all around the world within the framework of coffee culture by means of photography.

SFE and contact angle results varied depending on the plasma parameters. Oxygen plasma treatment (100 W-30 min) enhanced the hydrophilicity of PMMA surface as shown by decreasing the water contact angle from 70 degrees to 26 degrees. XPS analysis showed the change in the amounts of the present functionalities as well as formation of new groups as free carbonyl and carbonate groups. The roughness of the surface increased considerably from similar to 2 nm to similar to 75 nm after 100 W-30 min oxygen plasma treatment. ESR analysis indicated the introduction of peroxy radicals by oxygen plasma treatment, and the intensity of the radicals increased with increasing the applied power. Significant decrease in radical concentration was observed especially for the samples treated with higher powers when the samples were kept under the atmospheric conditions. As a conclusion, RF plasma, causes changes in the chemical and physical properties of the materials depending on the applied parameters, and can be used for the creation of specific groups or radicals to link or immobilize active molecules onto the surface of a material.

These interactions determine how the body elements accept the material. Thus, depending on the specific application area of the biomaterial, it is necessary to understand cell-material, tissue-material, and blood-material interactions in order to optimize the properties of the material. The response of the host organism to biomaterials at macroscopic, cellular, and molecular levels is especially related with the properties of the surface of the material as that is the part that first comes in contact and reacts. In implants, tissue engineering scaffolds, and many other biomedical fields, surface engineering of the biomaterial, especially of polymeric biomaterials, is often required, and the surface is modified physically and/or chemically. This demand is either in the direction of no cell adhesion, as in the case of stents, or in the opposite direction to promote cell adhesion and proliferation, as in tissue engineering applications. This chapter focuses on the principles and practices of surface engineering techniques applied to biomedical polymers and aims to provide an insight to the reader about the field. The physical, chemical, biological, and radiation techniques are discussed as well as some specific modifications to enhance the surface biocompatibility, blood compatibility, and antibacterial properties in an attempt to create a sophisticated, functional surface for specific biointeractions. © 2013 Wiley-VCH Verlag GmbH & Co.

Therefore, the study first draws a framework of the political consumer, political consumerism, and the effects of political consumerism. Then it investigates the link between the internet and social media use and the aforementioned concepts. In other words, the purpose of the study is to analyze the extent to which internet and social media use and increase the likelihood of engaging in political consumerism through the method of a case study. As a method of sampling, quota sampling method was chosen. The in-depth interviews were performed in a semistructured form to maintain the coherence and details. The results of this study and similar studies are thought to be beneficial for improving the quality of life for consumers, corporations, and governments related to agenda setting and policy making. © 2022, IGI Global.Book Part Political Consumerism and Social Networking Usage: a Case Study(IGI Global, 2021) Ozgen,O.; Sukuroglu,V.K.; Akar,B.The main purpose of the study is to reveal the relations between the internet and social media usage and the basic motives behind the actions and engagements of political consumers departing from the thoughts and individual experiences of scholars.
