Master Thesis Development of Reinforced Pmma Sheets for Office Furnitures and a New Junction Detail Proposal(Izmir Institute of Technology, 2006) Özçiftçi, Sibel; Ergül, EmreNowadays life styles are changing and more modern than before, for that reason peoples furniture desires are different. In this modern world; furniture using gain a meaning and play important role than before, it defines peopele.s social status and their posion in this life. Design criteria are changing and improving everyday because of this designers use different equipments for their desingns. Glass production which is diffucult to take a shape hence plastic meterials were common after World War II. Modern views and their strength transperent materials satisfied designers desires. After gained environment conclousness same plastics which are non recyling products were gave up to use. Light and high strength plastic which is a recyling material PMMA is very common to use PMMA as known as a brand which name is plexiglass in Turkey. Also this plastic materials have very effective features than others.. İn this study, transparent sheets, glass and PMMA which are used furniture production were studied. As a designer approach different examples and combine details are given.Combine details which are used furniture production were researched and PMMA panel's strength,variety and flexibility were suggested as an beneficial metarial. After the performance, for the office furnitures, there had been a suggestion on a material that brings positive reaction for its endurance, variation and elasticity to the PMMA plate which is more frequently preferred compared with glass. In the suggested material, putting galvanized matting string between the two PMMA plates resulted in stronger and more elasticity characteristics,compared to the standart PMMA plate. After the compose of the material, it had been put through durability test.As a result the material's bending durability had been calculated, too.Master Thesis Assessment of Lighting Performance of Pvc and Pmma Materials in Office Spaces in Terms of Visual Comfort(Izmir Institute of Technology, 2006) Öztürk, Müge; Ergül, EmreThis research tests the plastic materials which can provide properly diffused illumination level and have smooth transmittance performance. Among these materials, two of them, PVC (polyvinylchloride) and PMMA (polymethylmethacrylate) sheets are evaluated, compared with each other and application possibilities. Besides, one of most important evaluation criteria for efficient lighting in office spaces; transmission property of these materials is empirically tested in laboratory in the scope of this study. One of these, PMMA is produced on commercial purpose in Turkey and used with its well known name; Plexiglas and the other one; Barrisol is an officially registered trademark of PVC translucent strech sample used in test. This study is gathered by means of searching lighting literature, rather restricting the data about two specific plastic based materials used in offices and experimenting the transmission characteristics of plexiglas and Barrisol. Scientifically; transmitting and diffusing of a material are unattached properties and rather concerned with chemistry. But there is a measured certainity that Plexiglas has %92 and Barrisol %73 percentage of transmission value. The results of test also supports that; transmission percentage of plexiglas sample is higher than Barrisol. It is reached to the conclusion that; when light directly comes down on a workplane whithout being regularly dispersed, it will tire viewer.s eyes and deteriorate visual comfort, negatively affecting productivity in offices.
