Öğe The analysis of high school students' perceptions towards "environment" concept(2010) Kaya, H.; Coskun, M.; Aydin, F.This research was carried out to put forward high school students' metaphors towards environment concept. The study group of the research consisted of 136 students that attend Prof. Dr. Mumtaz Turhan Social Sciences High School in istanbul Turkey in the second term of 2009/2010 academic year. The data of the research were gathered by completing "Environment is like. because." statement. The analysis and interpretation of the data were done using the phenomenological science design and content analysis technique of qualitative research method. According to the findings of the research, high school students produced 60 valid metaphors towards "environment" concept. The metaphors mentioned were classified into seven conceptual categories (environment as the expression of pollution, beauty, life, space, importance, reflection and variation) in terms of their common features. The research results indicate that students produced more metaphors that emphasize the importance of environment followed by the metaphors that express reflection, space and beauty. In the suggestions section, it was emphasized that teachers should teach the concepts via metaphors and such applications should be carried out to different student groups, teachers, teacher candidates and parents. ©2010 Academic Journals.Öğe Central Serous Chorioretinopathy Developed Following Covid-19 Vaccine(Gazi Eye Foundation, 2023) Coskun, M.A 40-year-old male patient, an office worker, is a hospital staff. He applied with the complaint of sudden onset of blurred vision in the right eye. He stated that he had the first dose of inactivated covid vaccine (sinovac) 4 days ago in his story. In his examination, his vision was 0.5 in the right eye, 1.0 in the left eye, and his intraocular pressure was in both eyes. It was at the level of 15 mmHg. Biomicroscopically, the anterior segment looked natural. CSC was diagnosed in the FFA and OCT examinations.Treatment with oral acetazolamide (2x250 mg), topical nepafanac (4x1) was started. On the 13th day of the treatment, there was insufficient improvement in clinical findings, and oral acetazolamide was used. The dose was reduced (2x125 mg), oral epleronone (50 mg) was added. On the 70th day of the treatment, the vision in the right eye increased to full level in the control examination and it was observed that the retina returned to its normal appearance in the OCT examination. © 2023 Gazi Eye Foundation.

Groups were compared regarding age, gender, ischemia, duration of post-edema application, number of intravitreal injections. Intraocular pressures (IOP), central macular thickness (CMT) and logarithmic visual acuity (LVA) values were evaluated before injection and at months 1, 3 and 6 after injection. Statistical analyses were performed by SPSS 16.0. Results: Ischemia was present in 8 patients in group 1 and 13 patients in group 2 (p = 0.005). The mean number of injections was 2.41 ± 1.15 in group 1 and 1.66 ± 0.48 in group 2 (p = 0.007). The IOP was significantly higher at month 6 in group 1 (p = 0.018) and at month 3 in group 2 (p = 0.049). There was no statistical difference between LVA 3 and LVA 6 in group 1 (p=0.238). Among other parameters, there was significantly higher visual acuity level (p <0.05) with improvements up to 6 months. Although there was no statistical difference between LVA 1 and LVA 3 (p = 0.097) and between LVA 3 and LVA 6 (p = 0.397) in group 2, the visual acuity was progressively improved until month 6. There was statistically significant difference among other CMT values (p <0.05), although there was no statistical difference between CMT 3 and CMT 6 in Group 1 (p = 0.238). In group 2, there was no significant difference between CMT 1 and CMT 6 or CMT 3 and CMT 6 (p values 0.985, 0.414) but there were significant differences among other CMT values w (P <0.05). Conclusion: The intraocular pressure was found to be elevated in IVR group at month 6 and in IVD group at month 3. LVA remained low until month 6. While CMT was progressively decreased in the IVR group until month 6, it was decreased at month 1 followed by elevation at month 3 and further decreased at month 6 in the IVD group. © 2019 Gazi Eye Foundation.

The numerous attainments and disappointments of COVID-19 strategy comebacks provide an opportunity for reflection on the macroclimate program and advancement. The study reveals vital factors why inaction is consequential and hinder easing actions, people involvement approach, poverty multiplier effects; worldwide issues require cooperation. Regardless of these differences, the research exposed remarkable details of why climate change is a more challenging issue for public financial representatives. It necessitates fundamental and permanent renovations of the worldwide financial system. These actions prevent the epidemic, but profoundly, it works, boosted when disease alleviated. Vigorous socio-financial reformations ought to be executed immediately beforehand climate change stretches to disastrous magnitudes. Most of the adverse of climate change destruction could be so severe to human kinds in the forthcoming years, making it harder to build governmental urgency. Therefore, it is essential to emphasize that public institutes strengthened in coming back to the pandemic either scientifically or ecologically, from the grassroots to the transnational level. Communal responsiveness transmuted to promote the society backing required for lasting climate change and plaque plans. Illustrating this challenge's factual messages will organize public representatives and people for the long-standing solutions for climate change and future virus outbreaks. © 2023 by Apple Academic Press, Inc.

A total of 156 primary school students participated in the research in Ankara BILSEM schools in 2010-2011 academic year. As data gathering tool "Environment Attitude Scale" developed by Atasoy (2005) was used in the study in the form of survey model. In data analysis phase, frequency, percentage, arithmetic mean, t test and one way variance analysis (ANOVA) were used. According to the results of the study, gifted students have positive attitudes towards environment. Another result indicated that gifted students' attitudes towards environment showed significant differences according to "gender" and "class level" variants. ©2011 Academic Journals.Öğe Gifted students' opinions about "earthquake": A qualitative study(2011) Aydin, F.; Coskun, M.This study was carried out to put forth gifted students' perspectives towards "earthquake" concept. A total of 156 primary school students participated in the research in Ankara BLSEM schools in 2010- 2011 academic year. The data of the research was gathered by completing "The earthquake means., or I consider earthquake as." statement. In the analysis and interpretation of the data, content analysis technique was used. As a result, the majority of the gifted students stated earthquake as: "quakes due to the movements of earth crust", "destruction", "loss of property and life", "natural disaster", "death" and "calamity". According to the results of the research, the following suggestions were offered: 1) developing and spreading natural hazards education at gifted students' institutions should be handled seriously. 2) Educational programs should be prepared in order to build environmental conscious via social communicational tools. 3) Gifted students should be given opportunities in the projects towards educational programs in relation with earthquakes, in other words, natural hazards. © 2011 Academic Journals.Öğe Observation of the students' "earthquake" perceptions by means of phenomenographic analysis (primary education 7th grade - Turkey)(2010) Aydin, F.; Coskun, M.The purpose of this research is to define and explain how 7th grade students' in Turkey perceive "earthquake" concept using phenomenographic research methods. The research group of the study is comprised of 553 7th grade students in four cities (Ankara, Adana, Antalya and Karabük) in Turkey. The data of the research was gathered by students' completing "I think earthquake means...", "In my opinion earthquake is...". statement. After phenomenographic analysis "7 different earthquake definition categories" were determined. 22.6% of the 7th grade primary school students in Turkey who contributed the research defined the earthquake as "destruction of the buildings and death of people", 19.7% "shakes related to the movements of the earth crust and fult line", 19.5% "natural disaster", 13.8% "swinging of the ground", 11.6% "a natural disaster whose effects increases as a result of people's unconscious and insensible acts" and 10.7% as "a disaster whose defects can be reduced by taking the necessary precautions". © 2010 Academic Journals.Öğe Using Google Earth Engine Machine Learning Algorithms, Soil Variable Effects on Soil Organic Carbon in Karabük Province/Turkiye: Using Google Earth Engine Machine Learning Algorithms(King Saud University, 2024) Coskun, M.; Coskun, S.; Dündar, Ö.; Sarsici, N.The study area is Karabük province, and the research topic is to examine the influence of soil-related variables on soil organic carbon in Karabük province. The aim of the study is to determine the relationship between digital soil mapping and the correlation analysis of soil variables that affect the carbon stock stored by the soil. In the study, data from SoilGrids was gathered using Google Earth Engine (GEE) machine learning methods. The JavaScript coding language was used to generate maps of SoilGrids data in GEE. These spatial data were processed using Geographic Information Systems software, and multiple linear regression analysis was performed using the “IBM SPSS 20.0? program. Clay, sand, silt, pH (in water), organic carbon density, mass density, coarse fractions, cation exchange capacity (CEC), and nitrogen were considered as soil variables. According to the results obtained, the pH of the surface soils (0–5 cm) of the study area was 58–7: clay g/kg; 104–400 g/kg; sand; 214–460; silt; 331–510 g/kg; organic carbon density: 380–562 dg/dm3; nitrogen density: 2 920–7 683 cg/kg; mass density: 93.00–136.00 g/kg; coarse particles: 55–239 (Per10000); CEC: 215–348 mmol/kg; and SOC values varied between 286–374 dg/kg. Soil organic carbon (SOC) stock amounts varied between 286 and 374 dg/kg in surface (0–5 cm) soils. As a consequence of the studies, it was revealed that nitrogen had the strongest link with SOC, whereas clay had the lowest relationship. © 2024 The Authors
