Design courses in online education: Vocational school students’ opinions on design lessons in the online education process: Online eğitimde tasarım dersleri: Meslek yüksekokulu öğrencilerinin online eğitim sürecindeki tasarım derslerine ilişkin görüşleri

Çalışmanın problemini pandemi döneminde online gerçekleştirilen tasarım derslerinin etkinlik ve verimliliğinin sorgulanması oluşturmaktadır. Meslek yüksekokulu tasarım odaklı bölümlerde öğrenim gören öğrencilerin, alanlarında çok önemli ve yadsınamaz yere sahip olan tasarım derslerinin online eğitim sürecindeki durumu hakkındaki görüşlerini belirlemeyi amaçlayan çalışmanın katılımcılarını Eskişehir Teknik Üniversitesi Porsuk Meslek Yüksekokulu’nda 2020-2021 Güz ve Bahar Döneminde Masaüstü Yayıncılık dersini alan, daha önce de tasarım odaklı dersler aldığı bilinen Basım ve Yayım Teknolojileri Programı ile Grafik Tasarımı Programı öğrencileri oluşturmaktadır. Çalışma, mevcut durumun betimlendiği ve yarı yapılandırılmış görüşme yöntemi ile verilerin değerlendirildiği nitel durum çalışması olarak modellenmiştir. Veriler, 2020-2021 eğitim öğretim yılı bahar dönemi sonunda gerçekleştirilen yarı yapılandırılmış görüşme verilerinden oluşmaktadır. Elde edilen veriler Nvivo12 programı aracılığıyla tematik analiz şeklinde gerçekleştirilmiştir. Bu bağlamda “Online eğitimde teorik ve uygulamalı derslerin işlenişine ilişkin görüşler” ve “Online eğitimde gerçekleştirilen uygulamalı tasarım derslerine ilişkin görüşler” şeklinde iki ana temaya ulaşılmış ve değerlendirilmiştir. Çalışmada, literatürde yer alan ve farklı örneklem grupları ile yapılan diğer çalışmaların sonuçlarıyla paralel şekilde önlisans öğrencilerinde de sosyalleşme, motivasyon ve konsantrasyon eksikliği, malzeme temini, teknolojik yetersizlikler, donanım eksikliği konuları öne çıkan değerlendirmeler arasında yer almaktadır. Bununla birlikte farklı olarak önlisans öğrencilerinin istihdam edilebilirliği için çok önemli bir kazanım olan deneyim eksikliği yönündeki değerlendirmeler öne çıkmaktadır.

The study aims to determine the opinions of students studying in design-oriented departments of Vocational school about the state of design courses, which have a very important and undeniable place in their field, in the online education process. Students who were studying at Eskişehir Technical University Porsuk Vocational School, including Printing and Publishing Technology Program, Graphic Design Program, who have studied Desktop Publishing in the fall and Spring period of 2020-2021 and have studied design-oriented courses before. The study is modelled as a qualitative case study in which the current situation is described, and the data are evaluated using a semi-structured interview method. The data consists of semi-structured interview data conducted at the end of the spring semester of the 2020-2021 academic year. The data obtained were carried out in the form of thematic analysis through the program of Nvivo 12. In this context, two main themes were reached and evaluated as” Opinions on the processing of theoretical and applied courses in online education” and “Opinions on applied design courses conducted in online education". As a result of the study, in parallel with the results of other studies in the literature and conducted with different sample groups, the issues of socialization, lack of motivation and concentration, material supply, technological inadequacies, and lack of equipment in associate degree students are among the prominent evaluations. However, on the other hand, evaluations in the direction of "lack of experience", which is a very important gain for the employability of associate degree students, come to the fore.

       تهدف هذه الورقة إلى تحديد أفضل طرق تقدير المعلمات لمعاملات توزيع كامبل من النوع الأول تحت نظام الرقابة من النوع الثاني. لهذا الغرض، تم الاخذ في الحسبان إجراءات تقدير المعلمات الكلاسيكية و معلم بايسون. كما تم استخدام تقديرات الاحتمالية القصوى لإجراء تقدير المعلمة الكلاسيكي. كذلك تم اشتقاق التوزيعات المقاربة لهذه المقدرات. والتي ليس من الممكن الحصول على حلول صريحة لمقدرات بايسون. ولذلك ، تم أخذ تقنيات سلسلة ماركوف و مونت كارلو ولندلي في الاعتبار لتقدير المعلمات غير المعروفة. في تحليل بايسون ، من المهم جدًا تحديد تركيبة مناسبة من التوزيعات السابقة ودالة الخسارة. ولهذا، تم استخدام توزيعين مختلفين سابقين. أيضًا ، تم التحقق من تقديرات بايسون فيما يتعلق بالمعلمات ذات الأهمية في ظل وظائف الخسارة المختلفة. وتم اُستخدام خوارزمية جبز لأخذ العينات لإنشاء فترات بايسون ذات مصداقية. بعد ذلك ، تتم مقارنة كفاءات مقدرات الاحتمالية القصوى بمقدرات بايز من خلال دراسة محاكاة مونت كارلو واسعة النطاق. لقد ثبت أن مقدر بايسون أكثر كفاءة بكثير من مقدر الاحتمالية القصوى. أخيرًا ، تم أيضًا تقديم مثال واقعي لأغراض التطبيق.This paper aims to decide the best parameter estimation methods for the parameters of the Gumbel type-I distribution under the type-II censorship scheme. For this purpose, classical and Bayesian parameter estimation procedures are considered. The maximum likelihood estimators are used for the classical parameter estimation procedure. The asymptotic distributions of these estimators are also derived. It is not possible to obtain explicit solutions of Bayesian estimators. Therefore, Markov Chain Monte Carlo, and Lindley techniques are taken into account to estimate the unknown parameters. In Bayesian analysis, it is very important to determine an appropriate combination of a prior distribution and a loss function. Therefore, two different prior distributions are used. Also, the Bayesian estimators concerning the parameters of interest under various loss functions are investigated. The Gibbs sampling algorithm is used to construct the Bayesian credible intervals. Then, the efficiencies of the maximum likelihood estimators are compared with Bayesian estimators via an extensive Monte Carlo simulation study. It has been shown that the Bayesian estimators are considerably more efficient than the maximum likelihood estimators. Finally, a real-life example is also presented for application purposes

STATISTICAL INFERENCE FOR GEOMETRIC PROCESS WITH THE GENERALIZED RAYLEIGH DISTRIBUTION

In the present paper, statistical inference problem is considered for the geometric process (GP) by assuming the distribution of the first arrival time is generalized Rayleigh with the parameters $\alpha$ and $\lambda$. We use the maximum likelihood method for obtaining the ratio parameter of the GP and distributional parameters of the generalized Rayleigh distribution. By a series of Monte-Carlo simulations evaluated through the different samples of sizes small, moderate and large, we also compare the estimation performances of the maximum likelihood estimators with the other estimators available in the literature such as modified moment, modified L-moment, and modified least squares. Furthermore, we present two real-life dataset analyzes to show the modeling behavior of GP with generalized Rayleigh distribution

Potential of cottonseed oil as fish oil replacer in European Sea Bass feed formulation

Triplicate groups of 20 European sea bass (35 g) were fed five diets in which the added lipid was 100% fish oil (FO), 40% (CSO40), 60% (CSO60), 80% (CSO80) and 100% (CSO100) refined cottonseed oil (CSO), for a period of 120 days. Overall fish growth, feed conversion ratio and protein utilization were unaffected by dietary treatment, but hepatosomatic and visceral fat indexes increased with increasing dietary CSO. Fillet fatty acid composition of total lipids reflected the fatty acids in the test diets. The monounsaturated fatty acids were significantly higher in fillet of fish fed diet FO, CSO40 and CSO60 compared to other treatments while saturated and polyunsaturated fatty acids (PUFA) were not affected by the dietary treatment. Some fatty acids (18:0, 18:1n-9, 20:5n-3 and 22:6n-3) were present in higher concentration in fillet lipid than in the CSO100 dietary lipid indicating accumulation in fillet relative to test diets. Retention of n-3 LC-PUFA within the fillet was increasingly inefficient among fish fed increasing levels of FO. Thus, this study suggests that CSO can be considered as a relatively effective substitute for fish oil in European sea bass (35 g) in terms of growth performances and feed efficiency as far as fish meal is present in the diet

Ankara bölgesi pliyosen-pleyistosen paleosollerinin (Palaotopraklarının) paleoiklim modellemesi

TÜBİTAK ÇAYDAG01.12.201

Ankara civarı (Beypazarı-Çayırhan) miyosen yaşlı gölsel-karasal çökellerin devirsel sedimantoloji, sekans stratigrafisi, ve sedimanter jeokimya yöntemleri ile yüksek çözünürlükte incelenmesi

TÜBİTAK ÇAYDAG01.08.2009Bu projede Çayırhan, Davutoğlan, Beypazarı ve Ayaş civarları çalışılmış ve bu bölgelerin civarlarında yüzlek veren Çayırhan, Akpınar ve kısmen Kirmir Formasyonları içerisinde birbirini tamamlayan 7 değişik stratigrafik ölçülmüştür. Ölçülen detay stratigrafi kesitlerinde sedimantolojik, (mikrofasiyes ve sedimanter yapı analizi), jeokimyasal (ana ve iz elementler), XRD, duraylı izotop analizleri (δ13C ve δ18O) ve Sr izotop analizleri yapılmıştır. Ayrıca, devirsel stratigrafi, sekans stratigrafisi ve Fischer eğrisi uygulamaları da yapılmıştır. Elde edilen sonuçlar göl seviyesi değişimlerinin iklimsel etkili olduğunu ve küresel Miyosen iklim değişimleri ile paralellik gösterdiği tespit edilmiştir. Küçük ölçekli (Milankovitch devirleri) ve büyük ölçekli iklim değişikliklerinin varlığı sediman diziliminde farklı devirsellikler olarak gözlenmiş ve küçük ölçekli iklim değişikliklerinin havzayı denetleyen tektonik olaylardan etkilenmediklerini tespit edilmiştir. Yapılan sedimantolojik, devirsel stratigrafik, kil mineralojisi, palionolojik analizlere göre ölçülü istiflerin alt kısmında koyu renkli çamurtaşları, haki çamurtaşları, kireçtaşı ve jips ardalanmalarından oluşan devirler ıslak ve kuru iklim ardalanmalarını temsil etmektedir. Çayırhan istifin üst kısmında ise kırmızı ve yeşil çamurtaşlarının ve stramatolitik kireçtaşı/marn ile ardalanmalarının yine küçük ölçekte ıslak ve kuru iklim ardalanmalarını farklı litolojiler ile yansıttıkları tespit edilmiştir. Fakat büyük ölçekte bakıldığı zaman birbirini destekleyen tüm analiz bulguları sayesinde ve hatta duraylı izotop analizleri desteği ile de kesinleşen Üst Miyosen soğuk ve nemli iklimini ve takip eden Sıcak ve kurak iklim değişimlerini görmek mümkün olmaktadır. Havzayı denetleyen tektonik olayların iklim değişimine etkisi büyük ölçekte dolaylı olabileceği ortaya çıkmıştır. Havza kenarlarından yapılan gözlemlere göre havzadaki sediman gelimini kontrol eden yükselmiş ana kayaların farklılıkları yakın kısımlarda farklı tipte devirlerin oluşmasına sebep olmuştur. Buna rağmen küçük ölçekli iklim etkili devirsel çökellerin kayıtları tespit edilmiştir. Tektonik etkiler ile yükselen havzanın kapanması durumunda bile devirsellikler devam etmiştir.In this Project, Çayırhan, Davutoğlan, Beypazarı and Ayaş regions have been studied and 7 different stratigraphic sections have been measured within Çayırhan Formation, Akpınar Limestone and partially Kirmir Formation cropping out around these areas. Sedimentological (microfacies and sedimantary structures), geochemical (main and trace elements), XRD, stable isotpoe analysis (δ13C and δ18O) and Sr isotope analysis have been carried out along the measured stratigraphic sections. In addition to these, cyclostratigraphic, sequence stratigraphic and Fischer Plot analysis have been applied. It has been found that lake level fluctuations are climate controlled and paralel with Global Miocene climate changes. Small-scale (Milankovitch cycles) and large-scale climate changes have been recorded as different cyclic variations within sediments and it has been found that small-scale climate changes were not effected from tectonic events controlling the basin. Sedimentolocial, cyclostratigraphic, clay mineralocial, palynological analysis displayed that cycles composed of alternation of dark mudstones, dark grey-green coloured mudstones, limestones and gypsums represent wet and dry climate changes at the lower part of the measured section. At the upper part of the Çayırhan measured section, it has been determined that alternation of red and gren coloured mudstones, stromatolitic limestones/marls alro represents wet and dry climate changes with different lithologic expression. For the large-scale changes, it is possible to see cold and wet climate and followed by dry and hot climate changes of Late Miocene in this basin by the results of the all analysis supporting each other and even with the support of stable isotope analysis. It has been detected that large-scale climate changes could probably indirectly effected by tectonic events controlling the basin. In the basin margins, different basement rocks exposed controlling the sediment influx into the basin could caused formation of the different cycles. However, climate-induced small-scale cycles have been recorded without tectonic distruption even in the period of closing of the basin

Neurobrucellosis with transient ischemic attack, vasculopathic changes, intracerebral granulomas and basal ganglia infarction: a case report

<p>Abstract</p> <p>Introduction</p> <p>Central nervous system involvement is a rare but serious manifestation of brucellosis. We present an unusual case of neurobrucellosis with transient ischemic attack, intracerebral vasculopathy granulomas, seizures, and paralysis of sixth and seventh cranial nerves.</p> <p>Case presentation</p> <p>A 17-year-old Caucasian man presented with nausea and vomiting, headache, double vision and he gave a history of weakness in the left arm, speech disturbance and imbalance. Physical examination revealed fever, doubtful neck stiffness and left abducens nerve paralysis. An analysis of his cerebrospinal fluid showed a pleocytosis (lymphocytes, 90%), high protein and low glucose levels. He developed generalized tonic-clonic seizures, facial paralysis and left hemiparesis. Cranial magnetic resonance imaging demonstrated intracerebral vasculitis, basal ganglia infarction and granulomas, mimicking the central nervous system involvement of tuberculosis. On the 31st day of his admission, neurobrucellosis was diagnosed with immunoglobulin M and immunoglobulin G positivity by standard tube agglutination test and enzyme-linked immunosorbent assay in both serum and cerebrospinal fluid samples (the tests had been negative until that day). He was treated successfully with trimethoprim and sulfamethoxazole, doxycyline and rifampicin for six months.</p> <p>Conclusions</p> <p>Our patient illustrates the importance of suspecting brucellosis as a cause of meningoencephalitis, even if cultures and serological tests are negative at the beginning of the disease. As a result, in patients who have a history of residence or travel to endemic areas, neurobrucellosis should be considered in the differential diagnosis of any neurologic symptoms. If initial tests fail, repetition of these tests at appropriate intervals along with complementary investigations are indicated.</p
