Item Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeğinin Türkçe Uyarlaması: Geçerlilik ve Güvenilirlik Çalışması(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2018) Avcı, Ummuhan; Ersoy, Halil; 0000-0001-7007-1478; 0000-0003-1598-7656Bu araştırmanın amacı Law, Lee ve Yu 2010 tarafından geliştirilen Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeği’ni Türkçe’ye uyarlamaktır. Bu amaçla geçerlik ve güvenirlik analizlerini yapmak üzere altı faktör bireysel tutum ve beklenti, zorlayıcı amaçlar, belirgin hedefler, ödül ve takdir, ceza, sosyal baskı ve rekabet ve 19 maddeden oluşan altılı Likert tipindeki ölçek, özel bir üniversitede okuyan 312 mühendislik fakültesi öğrencisine uygulanmıştır. Doğrulayıcı faktör analizi sonuçları incelendiğinde, ölçeğin altı faktörden oluştuğu doğrulanmış ve ölçeğin uyum iyiliği indislerinin yeterli düzeyde olduğu görülmüştür. Ölçeğin güvenilirliği Cronbach alfa iç tutarlılık katsayısı ile değerlendirilmiştir. Cronbach alfa katsayısının ölçeğin tamamında 0.90 olduğu ve faktörler bazında 0.71 ile 0.83 arasında değiştiği görülmüştür. Bu sonuçlar ölçeğin, bilgisayar programlama derslerinde öğrenme motivasyonunun ölçülmesinde geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir. The aim of this study is to adapt the Learning Motivation in Computer Programming Courses Scale developed by Law, Lee ve Yu 2010 to Turkish. In order to determine its validity and reliability, the scale consisting of 19 six-point Likert-type items within six factors individual attitude and expectation, challenging goals, clear direction, reward and recognition, punishment and social pressure and competition was applied to 312 engineering faculty students at a private university. When the results of the confirmatory factor analysis were examined, it was confirmed that the scale had six factors, and the goodness of fit indices are at an acceptable degree. The reliability of the scale was assessed by the Cronbach alpha internal consistency coefficient. The Cronbach’s alpha coefficiencies were found to be 0.90 for the whole scale and between 0.71 and 0.83 for the factors. These results show that scale is a valid and reliable measuring tool for learning motivation in computer programming coursesItem Yükseköğretimde Uzaktan Eğitim Uygulamalarının İncelenmesi: Türkiye Örneği(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2017) Cabi, Emine; Ersoy, Halil; 0000-0002-7488-0309; 0000-0003-1598-7656Bu çalışma 2010 yılından 2016 yılına kadar, Türkiye yükseköğretiminde uzaktan eğitim çalışmalarının sayısal veriler ışığında incelenmesini amaçlamaktadır. 2010 ile 2016 yılları arasındaki yükseköğretimdeki öğrenci sayıları, uzaktan eğitim veren ön lisans, lisans ve yüksek lisans programlarına yerleşen öğrenci sayıları ve mevcut program sayılarının dağılımları incelenmiştir. Ön lisans ve lisans seviyesinde 20102015 arası uzaktan eğitimde öğrenim gören öğrenci sayılarına ulaşılabilirken, yüksek lisans seviyesinde sadece 2014-2015 ve 2015-2016 eğitim-öğretim dönemlerindeki program ve öğrenci sayılarına ulaşılabilmiştir. Ayrıca çalışmada genel ve programlara yerleşen öğrenci sayılarının yıllara göre değişimleri de incelenmiştir. Yapılan çalışma durum çalışması olduğundan mevcut durumu boylamsal olarak ortaya koymaktadır. Bu bağlamda, yeni açılması düşünülen uzaktan eğitim programlarının yapılandırılması çalışmalarında katkısı olabileceği düşünülmektedir. This study aims to investigate distance education implementations in higher education of Turkey from 2010 to 2016 by numeric data. For this purpose, the numbers and distribution of students at vocational schools, undergraduate and graduate level programs being executed totally in distance education method were analyzed. While it was possible to reach to the numbers of distant students at vocational schools and undergraduate levels between 2010 and 2015, only 2014-2015 and 2015-2016 years’ data were been able to obtained at graduate level. Moreover, the change in the numbers of distant students by years was investigated. Hence it is a case study, it portrays the existing situation longitudinally. In this context, it is believed that the study will contribute to the actions targeting to open new distance education programsItem The role of PET-CT in the evaluation of the response of the vertebra metastases in stereotactic radiosurgery(2019) Ozdemir, Yurday; Torun, Nese; Topkan, Erkan; 0000-0001-8120-7123; AAG-5629-2021; AAG-2213-2021Purpose: The aim of this study was to evaluate the role of positron emission tomography in assessing the response of stereotactic radiosurgery (SRS) for vertebral metastases(VM). Materials and Methods: Patients who received 16 Gy or 18 Gy SRS with no history of vertebral compression fracture, proven histologies except small-cell lung carcinoma and hematologic malignancies which are known as radio sensitive tumors, available pre- and post SRS PET images were included. All vertebral segments were categorized according to spinal instability neoplastic score in terms of stability and PET Response Criteria in Solid Tumors (PERCIST) criteria was utilized for treatment response. Results: Seventy-five patients with 119 VS (101 single, 9 double VS) received SRS. Breast cancer (66.7%) was the commonest pathology. Most patients (70.6%) had SINS 06.The local control was achieved in 87.4% VS with a 1-year local relapse -free survival rate of 92.5%. The median PET-CT time for the first SRS response assessment was 3-months (range:1-3.5 months) and there were only 4 (3.3%)local relapses in contrast to the positive responses in the remainders (30.3% complete, 43.7% partial responses and 22.7% stabil disease). While there were 11 local relapses in the last PET-CT response, no patient experienced any relapse complete response was achieved in the first PET-CT.Complete response in the first PET-CT was correlated with positive response in the last PET CT also. Conclusion: First PET-CT response after SRS seems to be valuable in anticipation of both the final vertebral response status and planning of alternative interventions for non-responders.Item Turkish Thoracic Society Consensus Report: Interpretation of Spirometry(2019) Ulubay, Gaye; Dilektasli, Asli Gorek; Borekci, Sermin; Yildiz, Oznur; Kiyan, Esen; Gemicioglu, Bilun; Saryal, Sevgi; 0000-0003-2478-9985; 30664428; AAB-5064-2021Currently, the criteria for applying and evaluating spirometer measurements have been defined by American and European Respiratory Societies. Several pulmonary function test laboratories in Turkey as well as in the world use these standards. However, different interpretation results are observed in different pulmonary function test laboratories. This report is prepared to provide a basis for a standardized asssessment in our pulmonary function test in our country.Item Evaluation of Blood Culture Practices: Use of System (Epicenter) Data(2019) Basustaoglu, Ahmet; Suzuk Yildiz, Serap; Mumcuoglu, Ipek; Karahan, Zeynep Ceren; Ogunc, Dilara; Kaleli, Ilknur; Kursun, Senol; Evren, Ebru; Ozhak, Baysal Betil; Demir, Melek; Murray, Patrick; 30683035Sepsis is a serious clinical problem and estimated to be responsible for 18 million annual deaths worldwide. Therefore, the use and the rapid processing of blood cultures are important for the transition from empiric therapy to directed therapy. The aim of this study was to assess the best blood culture practices in Turkey. We have examined the collection practices and techniques at four different hospitals, and a total of 165.443 blood culture bottles were evaluated (2013-2015). At the preanalytical phase most of the data which were important and which could support hospital quality systems/practices were not entered into the HIS and EpiCenter system. At the analytical phase loading of the bottles and removal of positive bottles primarily occurred between 6:00 and 9:00 AM but the positivity rate of the bottles showed a homogeneous distribution throughout the day. In other words, there were significant delays at processing positive blood culture bottles related to laboratory workers. The effect of education regarding best practices, transition from single bottle to two bottle cultures was successful in all hospitals. Single bottle usage decreased below 10% in all hospitals. Significantly more positive cultures were detected at multiple cultures when compared with the single bottle collection practice. In retrospective patient records, it was seen that all the laboratories reported the results of Gram staining to the clinics. However, these data were not recorded to the Epicenter. The contamination rates of Ankara Numune Hospital and Akdeniz University Faculty of Medicine Hospital are 6.2% and 5.4% respectively, contamination rates were not reported in other hospitals. The most common isolates detected in blood cultures were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, Staphylococcus aureus, and Acinetobacter baumannii. The mean time for the detection of these organisms were less than 20 hours in the aerobic bottle and anaerobic bottles. A total of 79.6% of facultative anaerobic isolates were detected in both bottles; 9.8% were detected only in the aerobic bottles; 10.6% of the isolates were detected only in the anaerobic bottles. As a result, the educational efforts in Turkey have met with success for transition from collecting single bottle blood culture sets to two bottle blood cultures. However, further efforts are needed to increase the number of blood culture sets collected during a 24 hour's period. In addition, errors at the preanalytical, analytical and postanalytical periods (taking samples, loading bottles into the system and processing positive blood cultures) should be eliminated.Item An optimization for milling operation of Kevlar fiber-epoxy composite material using factorial design and goal programming methods(2019) Ic, Yusuf Tansel; Elaldi, Faruk; Kececi, Baris; Uzun, Gozde Onder; Limoncuoglu, Nur; Aksoy, Irem; 0000-0003-0592-6868; 0000-0002-2730-5993; AAI-1081-2020; AAG-5060-2019; F-1639-2011; AAC-4793-2019Kevlar fiber-epoxy composite material is extensively used in manufacturing areas because of the advantages of composite material's characteristics. It is usually processed by traditional machining methods but the drawbacks for determination of optimum cutting parameters might cause some material deformations during machining process. In this study, the cutting parameters are concurrently optimized by using the integrated 2k factorial design and goal programming methods for minimum delamination and minimum surface roughness of Kevlar fiber-epoxy composite and the best machining parameters have been obtained for the material. The results were compared with the results of the multi-criteria decision-based Taguchi methods.Item Clinical Features of Patients with Allergic Rhinitis and Evaluation of Adenoid Hypertrophy as a Comorbidity(2019) Sancakli, Ozlem; Belverenli, H.Objective: The nasal cavity is anatomically and functionally communicates with eyes, paranasal sinuses, nasopharynx, middle ear and lower airways. Therefore, comorbid diseases such as asthma, chronic sinusitis, adenoid hypertrophy allergic conjunctivitis are common in patients with allergic rhinitis. In our study, we aimed to evaluate the frequency of comorbid diseases, clinical features of patients who referred to our outpatient clinic with allergic rhinitis. Method: The study included children aged between 3-17 years who were diagnosed with moderate to severe allergic rhinitis between September 2015 and March 2016 in our pediatric allergy outpatient clinic. Patient files were retrospectively reviewed; comorbid diseases, family history, eosinophil percentage, total IgE level and allergy test results and the number of drugs used were recorded. In the first month of the treatment, visual analog scale was used to score the symptoms. P< 0.05 was considered significant in the statistical analysis. Results: A total of 106 patients (33 female, 73 male) with respective median ages of 7.25 and 5.13 years [range: 3.0-17.0, years] were included in the study. In 84.9% of our patients, skin test was positive, and in 69.8% of the patients the symptoms persisted for more than 2 years. The most common comorbid diseases were asthma (52.8%) and adenoid hypertrophy (30.2%). In our study, the incidence of adenoid hypertrophy was higher and total IgE levels were lower in the skin test-negative group (p=0.019, p=0.027). Conclusion: In our study, the most common comorbid diseases in patients with allergic rhinitis were asthma and adenoid hypertrophy, and in the skin test-negative group adenoid hypertrophy was more frequent.Item The Necessity of Sector Carrying Capacity in Multinational Companies' FDI Location Choice(2019) Baskici, Cigdem; Ercil, Yavuz; AAI-6607-2020The aim of this study is to define the carrying capacity as a new criterion in multinational companies' foreign direct investment (FDI) location choice. The validity of such a definition requires the existence of a causal relationship between FDI and the number of companies at the investment location. As carrying capacity is a function of the sector population, FDI refers to the decisions of foreign investors regarding location choice. With this in mind, the company numbers and FDI data used belonging to 34 sub-sectors of Agriculture, Industry and Services sectors in Turkey between the years of 2006-2016 were analyzed. The Granger causality test was applied to investigate the causal relationship between the company numbers and FDI. As a result of the findings, a causality relationship between the number of companies and FDI was determined in 29 of the 34 sub-sectors. A causality relationship could not be found in 2 sub-sectors. Analysis was not possible in the remaining 3 sub-sectors because of a lack of data. The results show that carrying capacity can be used as decision criterion in multinational companies' FDI location choice. In addition to this main result of the study, predictions for the investment decision are presented in the light of the analyses along with evaluations of the carrying capacity of the Agriculture, Industrial and Services sectors.Item Interior Design Approach As Part of Passive Fire Safety Measures - Evaluation of the Re-Used Historical Bandabuliya Building Evacuation System(2019) Bilge, BetulThe risks that emerge during an emergency and disasters as well as the damages caused by such risks adversely affect human lives, the buildings they live in and the interiors of such buildings. Emergency and disaster management system is a holistic process. Within this process, the Interior Architects' command in the flow of management system is significant in terms of being acquainted with when to step in and at what point of the system flow to play a part. The risks that are revealed as a result of management activities and the requirements produced afterwards designate the necessity for taking and implementing measures beforehand. At this point, how important the indoor arrangements and planning are in terms of loss of lives and safety during and after an incident rises distinctively to the surface, apart from the structural arrangements intended for prevention and mitigation. The system built should demonstrate not attenuating but strengthening and supporting approaches in terms of a secure design. A safe architecture that has been established in line with legal requirements and regulations is an integral part of a system that cannot be abstracted from interior space. In the study, Interior Space Design Approaches as Part of "Passive Safety Measures"which area part of the emergency management system have been characterised. The system setup discussed pursuant to fire threat has identified the fundamental approach criteria in terms of a secure indoor evacuation. The purposed design system relation has been assessed on the historical Famagusta- Bandabuliya Building that has been refunctioned.Item 2019 Turkish Hypertension Consensus Report(2019) Aydogdu, Sinan; Guler, Kerim; Bayram, Fahri; Altun, Bulent; Derici, Ulver; Abaci, Adnan; Tukek, Tufan; Sabuncu, Tevfik; Arici, Mustafa; Erdem, Yunus; Ozin, Bulent; Sahin, Ibrahim; Erturk, Sehsuvar; Bittigen, Atilla; Tokgozoglu, Lale; 31483311The Turkish Hypertension Consensus Report was prepared for the first time in 2015 to adapt the European and American international guidelines to our clinical practice and to create a practical report that could be a basic reference for all physicians dealing with hypertensive patients. This report, which was prepared by a committee with representation from 5 leading hypertension associations, has been accepted and is widely used. New clinical studies in hypertension literature and updated international guidelines since 2015 have demanded an update of the Turkish Hypertension Consensus Report as well. In this updated 2019 report, blood pressure levels were classified as Normal, Elevated, Stage 1, and Stage 2 hypertension. A new section was added for secondary hypertension. It was specified that drug treatment may be initiated with any 1 or a combination of 4 groups of drugs (diuretics, calcium channel blockers, angiotensin-converting enzyme [ACE] inhibitors, and angiotensin receptor blockers [ARBs]), except a combination of an ACE inhibitor and an ARB. It was emphasized that beta-blockers may be a first choice for hypertension treatment in diseases such as atrial fibrillation, heart failure, and coronary artery disease. The initial recommendation for hypertension treatment is a combination therapy in patients with a blood pressure level >= 150/90 mmHg. Target blood pressure values were redefined according to age and the presence of comorbidities. The hypertension treatment algorithm was renewed; it is proposed that drug therapy can also be initiated with a risk-based approach for the group with an elevated blood pressure (systolic blood pressure: 120-139 mmHg, diastolic blood pressure: 80-89 mmHg). The threshold clinic systolic blood pressure level was reduced from 160 mmHg to >= 150 mmHg for the initiation of drug therapy in individuals 80 years of age or more. The section on the treatment of special groups has now been expanded to include pregnancy and lactation. As in the previous report, in this update, practical recommendations for the most common cases seen in the clinic were the goal, rather than a comprehensive report that addresses all aspects of hypertension. This report has evidence-based recommendations for most patients; however, it should be kept in mind that there may be differences from 1 patient to another and that physicians should take an individualized approach according to a good clinical evaluation.
