Dogal Afetler ve Cevre Dergisi , 2016, DOI: 10.21324/dacd.11236
Abstract: In Turkey settlement units enlarged, developed and spread within time due to increasing population and other developments. Starting from the declaration of Turkish Republic, work immigration occurred to Kocaeli province (Izmit city) together with developing industry and trade and accordingly the population of the city increased. One of the most important problems of the city, population of which rapidly increases since 1950's is accommodation. The accommodation problem was tried to be solved by residents built by state and private sector but residential building problem gained a new dimension after the Marmara earthquake in year 1999. New areas of settlement were determined in Izmit city by the studies initiated after 1999 earthquake. The development of these settlement areas accelerated after 2000's. The urban conversion applications in recent years have also been a triggering effect for the development of settlement areas. Together with the construction of new settlement areas, cross sectional area and population of these areas increased and various problems appeared such as environmental, infrastructure and superstructure problems. Noise, air pollution, domestic wastes and visual pollution constitute the important problems in new settlement areas. Under the scope of this study, reasons of population increase and formation of new settlement areas in Izmit city, Yahyakaptan neighbourhood will be presented, findings about environmental effect of new settlement area on the neighbourhood will be submitted by comparing resident typologies and resident usage requirement and finally solid waste amount according to increasing settlements and population in the region will be examined from environmental engineering point of view, according to TUIK (Turkish Statistics Institution) annual waste amount calculation methods and solutions will be suggested for domestic waste problem.

Kazm Demirarslan, Halil Ak?nc?
Dogal Afetler ve Cevre Dergisi , 2016, DOI: 10.21324/dacd.29373
Abstract: Factors like unplanned urbanization, transportation and industry in Eastern Black Sea cause significant adverse effects in this region. One of these effects is the air pollution. Air pollution reduces the life quality in cities and also it brings about many health problems. Especially, in winter, fossil fuels are used for the purpose of commercial heating and these fuels cause serious air pollution in the region. One of the important sources which may lead to air pollution in research area is coastal road of Black Sea. This road extends from borderline of Georgia to western Black Sea Region of Turkey and is an important route for transportation. The effects and dispersions of PM10 pollutant in the provinces of Artvin, Bayburt, Giresun, Gümü?hane, Ordu, Rize and Trabzon located along the Eastern Black Sea Region were investigated using maps generated by Geographic Information Systems (GIS). Data related to air quality was obtained from the hourly measurements of the stations used by the Ministry Environment and Urban Planning between 2010 and 2015. According to the study results, it was determined that, in specified date range, the concentrations of PM10 were high; in all seasons for Trabzon and Gümü?hane, in the summer, autumn and winter seasons for Bayburt and especially in the autumn for Ordu.

Dogal Afetler ve Cevre Dergisi , 2016, DOI: 10.21324/dacd.91087
Abstract: Air pollution occurs more particularly in areas where there are an intense and unplanned urbanization. Because of the pollution, air quality is reduced and the pollution causes the various health problems. In this study, sulphurdioxide (SO2) concentration distributions has been examined in The Eastern Black Sea region where decreasing air quality because of the non-planned urbanization and topographical reasons. Fossil fuels used for heating especially in the winter season lead to air pollution dramatically. The Black Sea Coast could be one of the major sources of the air pollution in the study area. In this study, the effects and distributions of SO2 polluter on air quality is investigated by produced maps with the help of geographical information systems in the area of Eastern Black Sea zone that has Artvin, Bayburt, Giresun, Gumushane, Ordu, Rize, and Trabzon cities.The related data of air quality, measurement stations which are belonging to The Ministry of Environment and Urbanization, have been used to measure hourly data between 2011-2016 years. The outcomes of this study, the means of SO2 concentrations ranking is found in spring seasons, Ordu > Giresun > Trabzon > Gumushane > Rize > Bayburt > Artvin, in summer seasons, Trabzon > Giresun > Rize > Ordu > Artvin > Bayburt, in fall seasons, Trabzon > Ordu > Gumushane > Giresun > Bayburt > Artvin > Rize, in winter seasons, Ordu > Trabzon > Gumushane > Giresun > Bayburt > Artvin > Rize.
Evaluating Dispersion of Residential CO and NOx Emissions with the Help of Different Models in K?rfez District, Kocaeli Province
Kazm Demirarslan, ?enay ?etin Do?ruparmak
Dogal Afetler ve Cevre Dergisi , 2015, DOI: 10.21324/dacd.55055
Abstract: This study was conducted to investigate the dispersion of spatial source CO and NOx emissions with the help of different models in Korfez District, Kocaeli Province. Emissions from residential areas were chosen as the spatial source in the region and residents were divided into four different sections. The residential area is 5.31 km2 and natural gas, fuel-oil, wood, and coal are used as heating fuels in this district. With the help of the obtained data, emission rates were calculated using the mass-based emission factors of U.S. Environmental Protection Agency. These ratios were divided into residential areas and data were obtained in g/s.m2 and these data were entered to AERMOD, ISCST-3 and CALPUFF VIEW programs for the purpose of modelling. As a result of the modelling study, daily and annual dispersion maps were obtained. When the maps were examined, with AERMOD, the daily maximum concentrations of CO and NO were estimated to be 651,27 μg/m3, 18,29 μg/m3 while the annual concentrations were found as 128,47 μg/m3 and 2,90 μg/m3, respectively. The obtained daily maximum CO and NOx values with the help of ISCST-3 program were as 290,29 μg/m3 and 11,77 μg/m3 and the maximum annual values were as 86,48 μg/m3 and 1,95 μg/m3, respectively. The values of CO and NOx emissions obtained with the help of CALPUFF modelling program were as 692,67 μg/m3 and 15,64 μg/m3 , respectively, on daily basis and as 124,08 μg/m3 and 4,53 μg/m3 respectively, on annual basis. While there seemed to be a similarity in all three programs for CO when considering dispersion directions on the distribution maps, it was pointed out that the concentrations dispersed in the direction of east and west of Korfez district on AERMOD and CALPUFF maps as this dispersion was towards to the west of the county on ISCST-3 map. On NOx distribution maps, the residential areas of Korfez district were observed as the locations of density for NOx. The concentration propagation directions were same for all three programs particularly for annual dispersions maps and the concentration levels at receiver points in these directions were also determined as equal.
Biomaterials and Tissue Engineering for Regenerative Repair of Articular Cartilage Defects
Kazm Tur
Turkish Journal of Rheumatology , 2009,
Abstract: Articular cartilage defects heal very poorly and lead to degenerative arthritis. Existing medications cannot promote healing process; cartilage defects eventually require surgical replacements with autografts. As there is not enough source of articular cartilage that can be donated for autografting, materials that promote cartilage regeneration are important in both research and clinical applications. Tissue engineering involves cell growth on biomaterial scaffolds in vitro. These cells are then injected into cartilage defects for biological in vivo regeneration of the cartilage tissue. This review aims first to provide a brief introduction to the types of materials in medicine (biomaterials), to their roles in treatment of diseases, and to design factors and general requirements of biomaterials. Then, it attempts to sum up the recent advances in engineering articular cartilage; one of the most challenging area of study in biomaterials based tissue engineering, as an example to the research on regenerative solutions to musculoskeletal problems with an emphasis on the biomaterials that have been developed as scaffolds for cartilage tissue engineering. The definitive goal on cartilage regeneration is to develop a system using biomimetic approach to produce cartilage tissue that mimics native tissue properties, provides rapid restoration of tissue function, and is clinically translatable. This is obviously an ambitious goal; however, significant progress have been made in recent years; and further advances in materials design and technology will pave the way for creating significantly custom-made cellular environment for cartilage regeneration.

Demir, Ibrahim;Mavi, Kazm;
Brazilian Archives of Biology and Technology , 2008, DOI: 10.1590/S1516-89132008000500004
Abstract: germination percentage, seedling fresh weight and sensitivity index of the pepper (capsicum annuum l. cv. sera demre) seed lots harvested 50, 60 and 70 days after the anthesis (daa) in 2001 and 2002 were determined under the salt (nacl) and osmotic (peg) stresses at the same water potentials of -0.3, -0.6 and -0.9 mpa. the objective was to study whether the germination and seedling growth were inhibited by the salt toxicity or osmotic effect during the development. the higher the salt and osmotic stress concentrations the lower was the germination percentage and seedling fresh weight. the seed germination was higher and sensitivity index were lower in nacl than in peg at the same water potential and harvest in both the years. they were able to germinate at all the concentrations of nacl but at -0.9 mpa of peg, none of the seeds of any harvest germinated in both the years. the seeds harvested 70 daa showed the highest germination and seedling weight in all the nacl and peg concentrations in both the years. results showed that the inhibition of the germination at the same water potential of nacl and peg resulted from the osmotic effect rather than the salt toxicity. moreover, the seeds harvested 70 daa appeared to be more tolerant to the salt and osmotic water stress conditions than the other two lots.

Beytulhikme : An International Journal of Philosophy , 2012,
Abstract: When both religious or theological background in Spinoza’s own thought and philosophical or theological background in his writings is not ignored, just then it can be a matter of understanding and perception him healthily. Spinoza is one of the most controversial philosophers in terms of religious, theological and philosophical understanding in the history of philosophy, and as long as to be read and perceived correctly his work Theological-Political Treatise, there will go away lots of misunderstanding attributed to him. Here in this paper, we will point out the significant points to take into account on reading and understanding of the aforementioned treligious and philosophical work which to contribute to understanding of Spinoza’s philosophy entirely in truest and health.

Erkan Tabancal?,Kazm ?elik
International Journal of Human Sciences , 2013,
Abstract: In this research, the relationship between academic self-efficacy beliefs and teachers' sense of efficacy were investigated for teacher candidate. The research is a descriptive study in relational screening model. Two separate instruments were used to collect data: the Academic Self-efficacy Scale to measure academic self-efficacy, and Teacher Self-efficacy Scale to measure the self-efficacy perceptions of teacher candidate. Mann Whitney U and Kruskal Wallis tests were conducted since the data were not normally distributed. The study group was comprised of 250 teacher candidate. The result of the study indicated that academic self-efficacy beliefs and teachers' sense of teacher candidates were quite high. Additionally it was found out that teacher candidates who had higher level of academic self-efficacy beliefs (comparing to teacher candidates who had moderate or lower level of academic self-efficacy) practiced better in each dimension of Teacher's Self-Efficacy Belief Scale (except for academic development). There wasn't a significant difference according to neither gender nor having a job or not. But there was a significant difference in the dimension of effective learning and teaching process according to teacher candidates' majors of study in favour of Social Sciences. Besides there was a significant difference in the dimension of creating positive classroom environment and academic self-efficacy in terms of their ages in favor of 20 year-old and below.

Dogal Afetler ve Cevre Dergisi , 2016, DOI: 10.21324/dacd.84380
Abstract: Earthquake is a significant natural incident which harms the people by affecting the housing settlements, in which they live in, developed by the cultures of the societies. The accurate planning of the housing spaces and building them seismically safe decreases these harms of the earthquakes. Nonetheless, the household goods that we use inside affect the internal space planning because of their habitual use and thus also affect the building, and the people and household goods inside during the earthquake. When the damages occurred in Turkey and Japan are examined, which are both located on the significant seismic zones, it is observed that demolition, damage, and injuries are encountered more in Turkey. Learning to live with the earthquakes and designing earthquake resistant buildings have become a lifestyle in Japan. Undoubtedly, the effects of the traditional Japanese lifestyle on the contemporary internal design of the houses exist within this concept. With this purpose, in this paper, traditional and contemporary internal space habitual uses of Japan, which is accepted to solve its earthquake problems as regards to design, and Turkey, which has encountered great sufferings due to the earthquakes, are examined; and their differences and similarities were compared according to the non-structural earthquake hazards. Thus, a righteous solution according to the disaster management was aimed to be achieved in the study.
