An Investigation on the areas and locations of sunlight patches in patient rooms

Tanrıöver, Sezin
Explored in this study were the patterns of direct sunlight received by differentlyoriented patient rooms in healthcare facilities. Desktop Radiance 1.02® software was used to simulate conditions in a typical double patient room. The area and locations of sunlight patches on room surfaces were considered as analog indicators for the investigation. The setting was defined as Ankara, Turkey. Seven orientations and 3 positions of standard-size window openings were studied in different combinations at solstices and equinoxes, from sunrise to sunset on an hourly basis for comparison. Data compiled were statistically analyzed and results for various combinations of orientation and opening position recorded. All these showed that there was no difference in the total amount of direct sunlight received between rooms with different orientations but there was, with different opening positions. Orientation created a difference in the amount of direct sunlight when the room surfaces were studied separately. Rooms with right and left-shifted openings received direct sunlight mostly on walls while those with centered openings received direct sunlight mostly on floor surfaces. Results suggested there were sufficient grounds for further investigation focusing on decisions related to the design of patient rooms, such as layout (e.g., the location of beds) and to choice of surfacing materials, colors and textures.


A Genetic algorithm for healthcare facility location problem
İşbilir, Melike; Bayındır, Zeynep Pelin; İyigün, Cem; Department of Industrial Engineering (2016)
In this study, we consider the problem of locating emergency healthcare facilities in urban areas. Upon emergency occurrence, patients are directed to any one of the emergency centers with a likelihood that depends on the travel time. Moreover, the survival, that represents the severity of the consequences of the emergency situation, is also probabilistic and is a function of the travel time. A mathematical model is constructed under the objective of maximizing expected number of survivors while determining...
Understanding the perception towards using mHealth applications in practice: Physicians' perspective
Sezgin, Emre; Özkan Yıldırım, Sevgi; Yıldırım, İbrahim Soner (2018-03-01)
The objective of this study was to investigate physicians' perceptions to use mobile health applications in practice, and to identify influencing factors to use the technology. An mHealth technology acceptance model was proposed (M-TAM), and a cross-sectional survey was implemented using structured questionnaire to collect data. Online tools were used for inviting participants (physicians) and data collection from Turkey. The data was analyzed using Confirmatory Factor Analysis (CFA) and Structural Equation...
Investigation of surface structure and biocompatibility of chitosan-coated zirconia and alumina dental abutments

Background: For long-term success of dental implants, it is essential to maintain the health of the surrounding soft tissue barrier, which protects the bone-implant interface from the microorganisms. Although implants based on titanium and its alloys still dominate the dental implant market, alumina (Al2O3) and zirconia (ZrO2) implant systems are widely used in the area. However, they provide smooth and bioinert surfaces in the transmucosal region, which poorly integrate with the surrounding tissues.
An analysis of the maincritical factors that affect the acceptance of technology in hospital management systems
Peker, Can; Özkan Yıldırım, Sevgi; Department of Information Systems (2010)
The purpose of this study is to develop a methodology by extending the Technology Acceptance Model (Davis, 1989) in order to contribute the acceptance of Hospital Management Systems in hospitals. The study also aims to extend the TAM by adding external variables. Thereby the relationships between perceived usefulness, perceived ease of use and external TAM factors and how these relationships will affect the behavioral intention to use the technology will be determined. In this study quantitative research me...
A Survey to Determine Security and Privacy Measures Needed for Genetic Information Exchange in Personal Health Records
Özkan, Özlem; Arsev Umur, Aydınoğlu; Aydın Son, Yeşim (2015-06-19)
In this study, our main focus was to understand necessities of a Personal Health Records (PHR) System for managing individuals’ health and genetic information. Recently the outcomes of Human Genome Project have begun to transform the clinic practice but still there is very limited number of studies in the area of genetic information exchange. Especially, the management of genetic information in the electronic environment and concerns about its security and privacy requires further research at national and i...
