AslSabuncu, Filiz Sunar
Dogal Afetler ve Cevre Dergisi , 2017, DOI: 10.21324/dacd.271091
Abstract: Earthquakes are the most destructive natural disasters, causing massive loss of life, infrastructure damages and serious financial losses. Earthquake-induced building damage detection is a very important step after earthquakes since such buildings pose a risk for cities. The recent advances in digital photogrammetry/remote sensing technology and satellite sensor/camera systems have inspired to emerge new and different research areas and applications. With the development of digital camera technology since 1950's, it has become possible to produce orthophotos with high spatial resolution and positional accuracy. These orthophotos are used successfully in the extraction of the details and the thematic classification. Depending on the high spatial image resolutions, the use of object-based approach has gained importance and has become widespread rather than the traditional pixel-based approach in the thematic classification. The town of Erci? in Van province, situated in the eastern part of Turkey, was selected for the study. In this region, an earthquake with moment magnitude (Mw) of 7.2 was occurred at 10:41 UTC (13:41 local time) on October 23th, 2011. In this study, the orthophotos produced from the aerial photographs taken one day after the earthquake by the General Command of Mapping for the purpose of damage detection. In the post-earthquake ortophotos, 2 different types of sites were selected as the study areas. As an initial step, segmentation process was carried out by selecting the most suitable parameters for the classification of both homogenous and heterogeneous areas. In the segmentation phase, the multi-resolution algorithm was utilized. After doing different trials, the most suitable shape factor and compactness values were considered. In the next step, two different classification approaches, namely “supervised” and “unsupervised”, used within the object based image classification were applied and their classification accuracies were compared.

Abstract: Objective: The aim of this study was to investigate the importance of the clinical experience on the reliability of the GOSLON Yardstick. Design: Comparative-measures study. Material: 3D images of the study models of children with complete unilateral cleft lip and palate (n: 119) at an average age of 9 years were included to the study. All subjects had their cleft lip and palate repaired in many hospitals by different surgeons, but no alveolar graft or any orthodontic treatment was performed. Method: Digital views of the models were used by Orthomodel software program. 3D images of the study models were scored by two groups of raters (Group I: 10 experienced orthodontists, Group II: 10 post-graduate orthodontic stu-dents) after careful perusal of published literature concerning GOSLON scoring and examining dental models samples. Main outcome measures: Statistics of intra- and inter-rater agreement. Results: Intra-rater agreement measurements of the two groups were high and high inter-rater agreement was also found between the two groups. Conclusion: Based on the results of this study clinical orthodontic experience does not affect significantly the reliability of the GOSLON Yardstick when all the raters trained before scoring.

Data collected in two-dimensional projections give planar images of object at each projection angle. To obtain information along the depth of the object, tomographic images are reconstructed using these projections. There are basically two approaches to solve the problem of reconstruction: analytical and iterative, each one presenting its own advantages and limitations. This paper provides a detailed introduction and comparison to four analytical image reconstruction methods including Fourier transformation, simple back-projection, back-projection filtering and filtered back-projection.

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.47A004

Lake Uluabat, having an international significance and subject to the Ramsar Convention, is fed by the basin of Mustafakemalpasa Stream which runs through fertile lands utilized for livestock breeding and agriculture. In this study, total amount of nitrogen (TN) and phosphorus (TP) loads of non-point pollutants (agriculture, livestock breeding, vegetation, surface runoff and small settlements) was calculated. It was found out that most intensive pollution load stemmed from livestock breeding which causes dispersion of 13653.57 tons·year-1 of TN and 3224.45 tons·year-1 of TP into the Lake Uluabat. Additionally, seasonal changes in concentration of TN and TP were observed during the period of 2008-2009 in Lake Uluabat. It was concluded that the rise of agricultural activities in summer months was the reason underlying the increase in pollution during the months in question.

AIDS is one of the medical professional’s or young person ventures in third world countries like Iran. The growth of AIDS victims in the recent years has made a lot of global worries about cure process and other related issues to HIV problems in these countries. One of the effective groups in the study of AIDS patients is nurses who are in direct contact with patients. Our investigation led to study two variables “consciousness” and “vision” of nurses working in Imam Khomeini hospital of Tehran University of Medical Sciences. Based on the results we achieved that nurses have a low medium degree in the variables studied which is as a result of poor and low effective trainings. In addition to this as a consequence of wrong culture in Iran about AIDS patients or even people in contact with them, nurses have been in a great pressure as they might be in danger of disease transmission. This negative trend has caused a great anxiety about the real condition of AID patients in Iran and their cure process.

The Effects of Food Irradiation on Nutrition and Health

Pakistan Journal of Social Sciences , 2012,
Abstract: Food irradiation is the process of exposing food to ionizing radiation at different doses in order to disinfest, sterilize, or preserve food. Administered hygienically at low doses, it extends shelf life and delays the ripening or sprouting of fruits and vegetables. At higher doses, it eliminates insects, moulds, bacteria and other potentially harmful micro-organisms that cause spoilage in foods. In today s increasingly densely populated world, where half of the global population lives in near-starvation conditions, the provision of sufficient and safe food is a high priority concern. Irradiation is a safe and effective method of food preservation used in many countries around the world. The present study examines the effects of the fast-growing irradiation technology on nutrition and health.

Abstract: The overriding view seeks solutions for environmental problems mostly in the positive sciences (natural sciences, engineering), not in the social processes that, indeed, the main cause of the problems. This understanding dominates especially in the ‘emerging economy’ countries, such as Turkey. However, the real solutions for environmental problems can be found at the intersection of positive science and social science disciplines. The main goal of the article is determine how environment and its problems should be deal with in the disciplines, as city planning, that also have practice, and scrutinize that environment concept has social science dimension as much as positive science dimension. Secondly, to open up discussion how environment concept is perceived in the developing countries. To reach the goals, first, I will examine environmental discourses in order to understand the environment concept in social sciences, than I will elaborate the dimensions and the meaning of the environment concept for the developing countries through environmental discourses. evre ile ilgili sorunlar n ele al n nda hakim olan dü ünce, fen bilimleri er evesinde geli tirilen zümlere ncelik verir, sorunlar n ortaya k n n as l nedeni olan sosyal dü ünce ve sistemi zümün bir par as olarak g rmez.

Music Perception as a Topic of Cognitive Psychology = Bili sel Psikolojinin Bir Konusu Olarak Müzik Alg s
Dogus University Journal , 2007,
Abstract: Music perception has a long and distinguished history as a topic of psychological research because music requires a mental activity in humans. As a complex human activity, music perception is naturally an area of interest especially to cognitive psychology. Cognitive studies suggest that listener’s experience of a particular musical sequence is driven and at the same time constrained by the sounds registered by auditory mechanisms but also processed by available mental resources. This assumption indicates that researchers must take into account certain inherent limitations and capabilities of the listener. The main purpose of this paper is to discuss possible cognitive processes underlying music perception. The steps taken towards this purpose will be describing the structure of music and discussing the way that this structure is perceived by human cognition.
