Öğretmen Eğitiminde Vignette Tekniği ve Uygulamaları

Stories that have been used frequently in many studies in social sciences, including educational research, are categorized in four different types as follows: case studies, case stories, scenarios, and vignettes. In literature, the vignette has been frequently used incorrectly or interchangeably with other types of stories. The purpose of this study is to describe what vignette is as a technique, phases of creating a vignette, educational benefits and limitations of vignettes by using various examples of vignettes in order to guide researchers in the field of teacher education. In particular, the benefits of vignette technique as a data collection tool, instructional and assessment approaches, and how vignette technique has been integrated with technology in teacher education studies are discussed based on the findings of pertinent literature during the last decadeEğitim araştırmalarını da içine alan sosyal bilimler alanında yapılan çalışmaların birçoğunda sıkça kullanılmakta olan hikâyeler; örnek olay çalışması, örnek olay hikâyesi, senaryo ve vignette olmak üzere dört farklı formda ele alınmaktadır. Literatürde vignette tekniği diğer hikâye formları ile sıkça karıştırılmakta, bazı çalışmalarda ise bu terimler birbirlerinin yerine kullanılmaktadır. Bu çalışmanın amacı, vignettenin diğer hikâye formlarından ayrılan özelliklerini ortaya koyan çeşitli örnekler sunarak, vignette tekniğini öğretmen eğitimi üzerine çalışan araştırmacılara tanıtmak, oluşturulma basamaklarını, eğitimsel faydaları ve sınırlılıklarını ortaya koymaktır. Özellikle öğretmen eğitimi araştırmalarında son 10 yıldan beri vignette tekniğinin; veri toplama aracı, öğretim ve değerlendirme yaklaşımı olarak nasıl kullanıldığı ve teknoloji ile nasıl ilişkilendirildiği, ilgili literatür bulgularına dayalı tartışılmıştır

O EFEITO DO TREINO DE IMAGINAÇÃO MOTORA NO SUCESSO DO SERVIÇO DE TÊNIS

In this study, it was aimed to reveal the effect of motor imagination training on the hit of the service in the tennis game. 32 male tennis players between the ages of 18-25 participated in the study in the field of tennis in Kayseri. After the first measurements of age, height, body weight and Dewitt-Dugan service and ITN Service test of the athletes, control (n=16) and experimental (n=16) groups were separated by random method. While 8-week technical training was applied to both groups, technical and imagination trainings were applied to the experimental group. At the end of eight weeks, the final test values were taken. The obtained data were analyzed in the IBM-SPSS 25 for Windows package program. In the analysis, the data showed normal distribution. Descriptive statistics were shown with arithmetic mean and standard deviation. As a statistical comparison test, analysis of variance was applied in repeated measurements to see the main effects and the changes in the data with significant interaction over time. In order to reveal the change of the groups over time in the variables whose group time interaction was significant, the Bonfferroni test was applied and the group and time changes were compared. The significance level was taken as p <0.05. In the comparisons between the experimental and control groups; According to the results of analysis of variance in repeated measurements of Dewitt-Dugan service test, no statistically significant difference was found in group main effect, time main effect and group time interaction (p>0.05). According to the results of analysis of variance in repeated measurements in ITN service test measurements, no statistical difference was found in the group main effect (F=0.208, p=0.655, η2=0.015), while the time main effect (F=26.034, p<0.001, η2=0.465) and group time interaction A significant difference was found (F=12.305, p=0.001, η2=0.291). As a result, it can be said that 8-week motor imagination training is effective in more complex motor skills such as the ITN s test, while there is no difference in the tests that do not include complex skills such as Dewitt-Dugan.En este estudio, se pretendía revelar el efecto del entrenamiento de la imaginación motriz en el golpeo del saque en el juego de tenis. Veinticinco tenistas varones de entre 32 y 18 años participaron en el estudio realizado en un centro de tenis de Kayseri. Tras las mediciones iniciales de edad, altura, peso corporal, test de saque Dewitt-Dugan y test de saque ITN, se dividieron aleatoriamente los grupos de control (n=16) y experimental (n=16). Ambos grupos recibieron formación técnica durante 8 semanas, mientras que el grupo experimental recibió formación técnica y de imaginación. Al final de las ocho semanas, se tomaron los valores postest. Los datos obtenidos se analizaron en el programa IBM-SPSS 25 para Windows. En el análisis, los datos mostraron una distribución normal. Los estadísticos descriptivos se mostraron mediante la media aritmética y la desviación estándar. Como prueba estadística de comparación, se aplicó el análisis de varianza de medidas repetidas para ver los efectos principales y los cambios en los datos con interacción significativa a lo largo del tiempo. Para las variables con interacción significativa grupo-tiempo, se aplicó la prueba de Bonfferroni para revelar los cambios de los grupos a lo largo del tiempo y se compararon los cambios de grupo y tiempo. El nivel de significación se tomó como p < 0,05. En las comparaciones entre los grupos experimental y de control, no se encontraron diferencias estadísticamente significativas en el efecto principal del grupo, el efecto principal del tiempo y la interacción grupo-tiempo según los resultados del análisis de varianza en medidas repetidas de la prueba de servicio de Dewitt-Dugan (p>0,05). Según los resultados del análisis de varianza en medidas repetidas de la prueba de servicio de ITN, no se encontraron diferencias estadísticamente significativas en el efecto principal de grupo (F=0,208, p=0,655, η2=0,015), el efecto principal de tiempo (F=26,034, p<0,001, η2=0,465) y la interacción grupo-tiempo (F=12,305, p=0,001, η2=0,291). Como resultado, puede decirse que el entrenamiento de la imaginación motriz de 8 semanas es eficaz en las habilidades motoras más complejas, como la prueba ITN, mientras que no hay diferencias en las pruebas que no incluyen habilidades complejas, como la prueba Dewitt-Dugan.Neste estudo, objetivou-se revelar o efeito do treino da imaginação motora no golpe do saque no jogo de tênis. 32 tenistas do sexo masculino com idades entre 18 e 25 anos participaram do estudo no campo de tênis em Kayseri.

ASELSAN'IN BÜYÜME VE KARLILIĞINA İLİŞKİN BOX-JENKİNS YÖNTEMİ İLE BİR ÖNGÖRÜ ÇALIŞMASI

Yapılan bu çalışmada, savunma sanayi sektörünün en başarılı firmalarından biri olan ASELSAN’nın bazı ekonomik verilerini (özsermaye kârlılığı- aktif kârlılık- özsermaye büyüme ve aktif büyüme) kullanarak uygun modeller kurmak, kurulan bu modellerle de gelecek dönemler için öngörülerde bulunmak amaçlanmıştır. Adı geçen firmadan elde edilen veriler, Box-Jenkins yöntemi yardımı ile analiz edilmiş ve öngörüler yapılmıştır. İlgili firmanın 1996-2018 yıllarını kapsayan 3’er aylık ekonomik verileri kullanılarak gerekli analizler yapılmış, uygun Box-Jenkins modelleri elde edilmiş ve bu modeller yardımıyla da 2019-2020 yıllarına ait 3’er aylık 8 dönem için öngörüler yapılmıştır. Yapılan öngörülere göre, gelecek dönemlerde ASELSAN’ın özsermaye karlılığı değerlerinin önce azalma, daha sonra çok hafif yükselme eğilimi göstereceği, aktif karlılık değerlerinin ise azalma eğilimi içerisinde olacağı anlaşılmaktadır. Yine özsermaye büyüme değerlerinin önce hafif bir dalgalanma gösterip daha sonra azalma eğiliminde olacağı, aktif büyüme değerlerinin ise önce hafif bir yükselme gösterip daha sonra azalarak ortalama civarında seyretme eğiliminde olacağı tespit edilmiştir

Ekosistem Hizmetleri ve Mekânsal Planlama İlişkisinin Peyzaj Planlama Çerçevesinde Değerlendirilmesi

Ekosistem yaklaşımı, doğanın korunmasını ve sürdürülebilir kullanımını teşvik etmekte, doğal kaynakların ve kültürel çeşitliliğe sahip insanların ekosistemlerin ayrılmaz bir parçası olduğunu kabul etmektedir. Bu yüzden; ekosistemlerin işleyişi ve hizmetlerinin anlaşılması önemlidir. Ekosistem hizmetleri, insanların ekosistemlerden sağladığı katkı veya faydalardır. Bu hizmetleri değerlendirmek için yapılan çalışmalar 1970’lerden bu yana giderek artmaktadır. Doğanın korunması, doğal kaynak yönetimi ve mekânsal planlama sürecine ekolojik değerlerin dahil edilmesi konusunda ekosistem hizmetleri yaklaşımı ekolojik, sosyal ve ekonomik değerlendirmeler sağlamaktadır.  Günümüzde, mekânsal planlarda, doğa koruma ve doğal kaynak yönetimi stratejilerinde yer verilen “çevre” ve “gelişme” kavramları arasında mutlak bir denge sağlanamadığı görülmektedir. Bu durum Türkiye’nin de taraf olduğu, Avrupa Peyzaj Sözleşmesi’nde; peyzajların korunması, yönetimi ve planlaması hususlarında yerel ve bölgesel çalışmaların yürütülmesi şeklinde de vurgulanmaktadır [5].  Ekosistem hizmetleri yaklaşımıyla mekânsal planlara ekolojik süreçleri dahil etmek mümkündür. Bu hizmetlerin belirlenmesi, haritalandırılması ve plan kararlarında yer verilmesi ile peyzajların korunması ve geliştirilmesi sağlanabilmektedir. Çalışmada, ekosistem hizmetlerinin ve sınıflarının kavramsal olarak anlaşılması ulusal / uluslararası literatür çerçevesinde ortaya konularak mekânsal planlama süreci, peyzaj planlama ve ekosistem hizmetlerinin ilişkisi, mekânsal planlar ve peyzaj planları ile ekosistem hizmetlerinin bütünleştirilmesi üzerinde durulmuştur. Ekosistem hizmetlerinin doğal kaynakların sürdürülebilir kullanımında bir planlama aracı olması gerekliliği vurgulanmaktadır. Sonuç olarak Türkiye’ de mekânsal planlama sürecinde ekosistem hizmetlerinin kullanımına ilişkin bazı öneriler getirilmiştir

Action Prediction in Humans and Robots

Efficient action prediction is of central importance for the fluent workflow between humans and equally so for human-robot interaction. To achieve prediction, actions can be encoded by a series of events, where every event corresponds to a change in a (static or dynamic) relation between some of the objects in a scene. Manipulation actions and others can be uniquely encoded this way and only, on average, less than 60% of the time series has to pass until an action can be predicted. Using a virtual reality setup and testing ten different manipulation actions, here we show that in most cases humans predict actions at the same event as the algorithm. In addition, we perform an in-depth analysis about the temporal gain resulting from such predictions when chaining actions and show in some robotic experiments that the percentage gain for humans and robots is approximately equal. Thus, if robots use this algorithm then their prediction-moments will be compatible to those of their human interaction partners, which should much benefit natural human-robot collaboration

Valor predictivo de los test preoperatorios para estimar la intubación difícil en pacientes sometidos a la laringoscopia directa para la cirugía de oído, nariz y garganta

ResumenJustificación y objetivosEl valor predictivo de los test preoperatorios para estimar la intubación difícil puede ser diferente en afecciones laríngeas. Se hizo una revisión de las historias clínicas de los pacientes sometidos a laringoscopia directa y una investigación del valor predictivo de los exámenes preoperatorios para estimar la intubación difícil.MétodosSelección de historias clínicas de los períodos preoperatorio e intraoperatorio y del sistema informatizado del hospital.ResultadosSe evaluaron 2.611 pacientes. En un 7,4% se detectaron intubaciones difíciles. Las intubaciones difíciles fueron constatadas en pacientes con una puntuación de Mallampati (escala de Mallampati [EM]) clase 4 (50%); clasificación de Cormack-Lehane grado 4 (95,7%); conocimiento previo de la vía aérea difícil (86,2%); restricción de la amplitud de movimientos del cuello (amplitud de movimientos cervical) (75,8%); distancia tiromentoniana corta (81,6%); y masa en las cuerdas vocales (849,5%) (p<0,0001). La EM tuvo una sensibilidad baja, mientras que la amplitud de movimientos cervical, tuvo la presencia de masa en las cuerdas vocales, distancia tiromentoniana corta y EM con un valor predictivo positivo relativamente mayor. La incidencia de intubaciones difíciles se incrementó 6.159 y 1.736 veces en cada nivel de aumento de los grados de la clasificación de Cormack-Lehane y de la clase de la EM, respectivamente. Cuando todos los test fueron considerados en su conjunto, la intubación difícil pudo ser clasificada con exactitud en un 96,3% de los casos.ConclusiónLos resultados de los test que prevén intubaciones difíciles en casos con laringoscopia directa coincidieron claramente con los resultados previstos en la literatura para las poblaciones de pacientes en general. Las diferencias en algunos resultados de los test, cuando se les comparó con los de la población en general, pueden ser debidas a las condiciones patológicas subyacentes de la laringe en las poblaciones de pacientes con intubación difícil.AbstractBackground and objectivesPredictive value of preoperative tests in estimating difficult intubation may differ in the laryngeal pathologies. Patients who had undergone direct laryngoscopy were reviewed, and predictive value of preoperative tests in estimating difficult intubation was investigated.MethodsPreoperative, and intraoperative anesthesia record forms, and computerized system of the hospital were screened.ResultsA total of 2.611 patients were assessed. In 7.4% of the patients, difficult intubations were detected. Difficult intubations were encountered in some of the patients with Mallampati scoring (MS) system class 4 (50%), Cormack–Lehane classification grade 4 (95.7%), previous knowledge of difficult airway (86.2%), restricted neck movements (cervical range of motion) (75.8%), short thyromental distance (81.6%), vocal cord mass (849.5%) as indicated in parentheses (P<.0001). MS had a low sensitivity, while restricted cervical range of motion, presence of a vocal cord mass, short thyromental distance, and MS each had a relatively higher positive predictive value. Incidence of difficult intubations increased 6.159 and 1.736-fold with each level of increase in Cormack–Lehane classification grade and MS class, respectively. When all tests were considered in combination difficult intubation could be classified accurately in 96.3% of the cases.ConclusionTest results predicting difficult intubations in cases with direct laryngoscopy had observedly overlapped with the results provided in the literature for the patient populations in general. Differences in some test results when compared with those of the general population might stem from the concomitant underlying laryngeal pathological conditions in patient populations with difficult intubation

Beta-glucan attenuates cerebral ischemia/reperfusion-induced neuronal injury in a C57BL/J6 mouse model

Beta-glucans (βg), that have many useful effects on human health, are natural polysaccharides. Our aim in this study was to determine useful effect of βg against oxidative and neuronal damage caused by global cerebral ischemia/reperfusion (IR) in stroke imitated mice via surgical operation. A total of 40 mice divided into four equal groups randomly. The group 1 (sham operated) was kept as control. Bilateral carotid arteries of subjects in group 2 (I/R) and group 4 (I/ R + βg) were clipped for 15 min, and the mice in group 4 (I/R + βg) were treated with βg (50 mg/kg/day), while the mice in group 2 (I/R) were treated with only vehicle for 10 days. The mice of group 3 (βg) were treated with βg for 10 days without carotid occlusion. Global cerebral I/R significantly increased oxidative stress and decreased members of antioxidant defense system. In addition, I/R caused histopathological damage in the brain tissue. However, βg treatment ameliorated both oxidative and histopathological effects of I/R. Our present study showed that βg treatment significantly ameliorated oxidative and histological damage in the brain tissue caused by cerebral I/R. Therefore, βg treatment can be used as supportive care for ischemic stroke patients

Bicycle Tourism in Konya Tourism Perspective And A Study On Its Effect On Marketing Konya Tourism As A Destination By Using PEST Analysis

Tourism is an important sector that its importance has globally been being understood day by day and has continuously been received quite much investment. It is obvious that it became an area of vital activity for Turkey and Konya in near past. The target of this study is to reveal the potential, its execution area and its contribution of bicycle tourism on Konya tourism. It has been considered that bicycle tourism, a new model of sustainability and diversification, will make a great contribution in city culture and Konya tourism in progress of time. To popularize using bicycle will prevent the young from harmful habits (smoking, alcohol, drug addiction etc.), and it will contribute in solving some serious and basic problems nowadays like obesity and stress, environment, traffic, public transportation and improving tourism and promoting Konya tourism by bringing touristic values into forefront. It has been considered that local administration’s efforts to improve the substructure for sportive activities in Konya having suitable topographic features for using bicycle deserve admiration. In this context, the bicycle routes and tourism subjects around Konya will have the opportunity of being promoted divergently by dealing Konya tourism potential and considering this potential having different presentation via bicycle tourism. Another inference about bicycle tourism is that it will strengthen and contribute in social networking and interaction among different social stratums as a result of using bicycle as an integrative tool for society

Vitamin D status in the first-trimester: effects of Vitamin D deficiency on pregnancy outcomes

Objective: To assess serum levels of 25-hydroxyvitamin D [25(OH)D] in the first trimester and to determine the factors affecting deficiency levels and its association with pregnancy outcomes.Methods: Serum 25(OH)D concentrations were measured at 11-14 weeks’ gestation in 229 singleton pregnancies using liquid chromatography-tandem mass spectrometry.Results: The median serum 25(OH)D concentration was 10.8 ng/mL and 45.9% of women had severe vitamin D deficiency with concentrations of &lt;10 ng/mL. Logistic regression analysis revealed that covered dressing style, lack of multivitamin intake, season of blood sampling (November-April) were factors associated with 25(OH)D deficiency. There was a negative correlation between 25(OH)D levels and gestational age at sampling. Low 25(OH)D levels were not associated with adverse pregnancy outcomes. Higher rate of cesarean section (CS) was noted in women with 25(OH)D ≥10 ng/mL compared to those with 25(OH)D &lt; 10mg/ml ( p= 0.01).Conclusion: A high prevalence of vitamin D deficiency was observed in early pregnancy which was related to dress code, use of multi-vitamins and season at sampling. Low 25(OH)D levels were not related with adverse pregnancy outcomes. Women with severe vitamin D deficiency were more likely to deliver vaginally.Keywords: 25-hydroxyvitamin D; pregnancy outcome; vitamin D deficienc
