The title compound prefers enol tautomeric form in solid state as to X-ray, IR and UV-Vis spectra results. Also, using the TD-DFT method, the electronic absorption spectra of the title compound was computed in both the gas phase and ethanol solvent. The calculated results support that the enol form is more stable than keto form. The molecular geometry from the X-ray single-crystal determination of the title compound in the ground state was compared at the B3LYP and B3PW91 levels of the density functional method (DFT) with the 6-311 + G(d,p) basis set. The harmonic vibrational frequencies of the title compound were calculated using the B3LYP and B3PW91 methods with the 6-311G+(d,p) basis set. The calculated results were compared with the experimental determination results of the compound. The potential energy surface scans about important torsion angels were performed by B3LYP/6-311 + G(d,p) level of theory for the title compound. The energetic behaviors of the title compound in the solvent media were also examined using the B3LYP and B3PW91 methods with the 6-311 + G(d,p) basis set applying the Onsager and the polarizable continuum model (PCM). Besides, the molecular electrostatic potential map (MEP), frontier molecular orbitals (FMO) analysis and thermodynamic properties for the title compound were obtained with the same levels of theory. The nonlinear optical properties (NLO) of the title compound were performed in the solvent media using the B3LYP and B3PW91 methods with the 6-311 + G(d,p) level using the PCM model.

Bu çalışmada, eğitim ihtiyaç analizlerinin yetkinliklere dayandırılarak yapılması gerekliliği savunulmuştur. Bu durumu incelemek amacıyla, 116 kişiden geri dönen 21 soruluk bir anket uygulanmıştır. Anket sonuçları, çoğunluğun eğitim ihtiyacı analizi yaptığını ve bu uygulamayı da yetkinlikler bazında değerlendirdiği görüşünü ispatlamıştır. Araştırma aynı zamanda, kişilerin iş tanımlarını yerine getirmek üzere gerekli yetkinlik düzeylerine sahip olduklarını ve iş tanımları kapsamında gerekli mesleki/ teknik eğitimleri aldıklarını da ortaya koymuştur. Ancak eğitim planlaması konusunda herkese eşit fırsat sağlanması konusunda belli bir miktarda inançsızlık tespit edilmekle birlikte, üst düzey çalışan kesiminin öncelik sırası olduğu görüşü de ortaya çıkmıştır. Bu durum, eğitim ihtiyaç analizi uygulaması içindeki bazı sistem aksaklıklarına işaret etmektedir.

Symbolic Reflections Of The Soul In Nuri Bilge Ceylan's Cinema: Representation Of Trees And Quest For Meaning
No full textİnsanın en kadim dostu olan ağaç, dünya kültürlerinde ortak unsurlardan biridir. Eski
insanlar ağaçları, toprak altından gökyüzüne ulaşan boyu, uzun yaşamı ve yüceliği
nedeniyle Tanrı ile bağ kurmaya aracı olabilecek yüce bir varlık olarak düşünmüşlerdir.
Hayat ağacı kavramı, bütün inanç sistemlerinde yer almıştır. Efsanelere, mitolojilere
konu olan ağaç; doğaldır ki sanatta da yer bulmuştur. Edebiyattan resme, şiirden
felsefeye; fotoğraftan sinemaya, ağaç ya doğrudan ya da metaforik olarak anlam
katmanları oluşturmuştur. Türk sinemasının önemli isimlerinden olan fotoğraf kökenli
sinemacı, auteur yönetmen Nuri Bilge Ceylan filmlerinde doğaya ve doğanın
karakterlerle olan ilişkisine önem vermiştir. Yönetmen, anlatım dilini güçlendiren bir
öğe olarak da özellikle ağaç görselini kullanmayı tercih etmektedir. Ağaç, doğanın
döngüsü, hayatın geçiciliği ve aynı zamanda insanların içsel yolculuklarını temsil
etmektedir. Ceylan’ın filmlerinde yansıtmak istediği derin melankoli, yalnızlık ve
boşluk hissi; boş yollar, kar yağışı ve ağaç temasıyla örülmüştür. Mevsim geçişleri ve
dolayısıyla zamanın geçişi çoğu sahnede ağacın temsiliyeti ile görülmektedir. Onun
sinemasında ağaçların temsili ve anlamı, sadece görsel bir motif olarak kalmaz; aynı
zamanda anlatısını destekleyen ve güçlendiren bir unsurdur. Bu eksende çalışmanın
amacı, Ceylan’ın görsel anlatıda sıklıkla kullandığı motiflerden biri olan ağaçların
sinemasındaki yerini ve anlamını analiz etmek ve metaforik olarak kullanımını
irdelemektir. Bunun için konuyla ilişkili doküman incelemesi, film taraması ve
betimsel analiz tekniği birlikte kullanılmıştır. Bu yöntemlerin birlikte kullanılmasının
çalışmanın metodolojisi açısından uygun olacağı düşünülmektedir. Dolayısıyla
çalışma, sinema ve sanat alanındaki ilgili araştırmalara yeni bir bakış açısı sunarak,
Ceylan sinemasının özgün ve etkileyici yönlerini daha iyi anlamamıza katkı
sağlayacağı düşünülmektedir.The tree, which is humanity's most ancient companion, is a common element in world
cultures. Ancient peoples considered trees to be noble entities capable of connecting
with the divine due to their towering height reaching from the ground to the sky, long
lifespan, and grandeur. The concept of the tree of life has appeared in all belief systems.
Trees, which are subjects of legends and mythology, naturally found their place in art.
From literature to painting, poetry to philosophy, from photography to cinema, trees
have created layers of meaning either directly or metaphorically. Nuri Bilge Ceylan, a
auteur director in Turkish cinema and a filmmaker with a background in photography,
has emphasized the relationship between nature and characters in his films. The director
particularly prefers to use the visual imagery of trees as a storytelling device, which
strengthens the narrative language. Trees symbolize the cycle of nature, the transience
of life, and simultaneously represent the inner journeys of individuals. The profound
melancholy, loneliness, and sense of emptiness that Ceylan aims to reflect in his films
are woven with themes of empty roads, snowfall, and the motif of trees. The transitions
of seasons and hence the passage of time are often depicted through the representation
of trees in many scenes. In his cinema, the representation and significance of trees go
beyond being merely visual motifs; they are elements that support and reinforce the
narrative. In this context, the aim of this study is to analyze the place and meaning of
trees in Ceylan’s cinema, one of the motifs frequently used in his visual narrative, and
to examine their metaphorical use. For this purpose, document analysis, film scanning,
and descriptive analysis techniques related to the subject have been used together. It is
believed that the combination of these methods is appropriate for the methodology of
the study. Therefore, the study is expected to offer a new perspective on relevant
research in cinema and art, contributing to a better understanding of the unique and
impactful aspects of Ceylan’s cinema

Bulgular: Çocuk Beden Koordinasyonu testinde öğrencilerin almış oldukları puanlar değerlendirildiğinde çalışma grubundaki öğrencilerin performanslarının kontrol grubuna kıyasla anlamlı düzeyde farklılık gösterdiği tespit edilmiştir (p < 0,05). Bu farklılık, hem erkek hem de kız öğrencilerde gözlemlenmiştir. Çalışma grubunda yer alan erkek öğrencilerin genel toplam puanlarında belirgin bir artış kaydedilmiş olup, son test sonuçlarına göre çalışma grubundaki erkek öğrencilerin puan ortalaması 203,90±30,17 olarak ölçülmüştür. Buna karşın, kontrol grubundaki erkek öğrencilerin son test puan ortalaması 141,40±43,79 olarak belirlenmiştir. Bu sonuç, çalışma grubu erkek öğrencilerinin koordinasyon düzeylerinde önemli bir iyileşme olduğunu göstermektedir. Benzer şekilde, çalışma grubundaki kız öğrencilerin toplam puanlarında da dikkat çekici bir artış görülmüştür. Çalışma grubundaki kız öğrencilerin son test puan ortalaması 188,00±25,39 iken, kontrol grubundaki kız öğrencilerin puan ortalaması 162,50±22,70 olarak hesaplanmıştır. Bu bulgu, kız öğrencilerde de çalışma grubunun uygulamalarının koordinasyon becerilerini geliştirme açısından etkili olduğunu göstermektedir. Genel olarak, Çocuk Beden Koordinasyonu testi toplam puanları açısından, çalışma grubu ile kontrol grubu arasında istatistiksel olarak anlamlı bir farklılık olduğu ortaya çıkmıştır (p < 0,05). Elde edilen sonuçlar, çalışma grubunda uygulanan yöntemlerin çocukların koordinasyon becerilerini geliştirmede etkili olduğunu ve bu etkinin hem erkek hem de kız öğrencilerde anlamlı düzeyde iyileşme sağladığını göstermektedir. Sonuç: Fiziksel Etkinlik Kartları ile yapılan temel hareket becerisi uygulamalarının, 7-10 yaş aralığındaki ilkokul öğrencilerinin beden koordinasyonunu geliştirmede etkili olduğu ve bu etkinin çalışma grubu lehine anlamlı bir fark sağladığı sonucuna ulaşılmıştır (p < 0,05).Objective: The effect of 8 weeks of basic movement skills on children's body coordination was examined. Material and Method: A total of 40 students, 20 girls and 20 boys between the ages of 7-10, participated in the study voluntarily. The Child Body Coordination motor skill test was applied to measure the motor development levels of the children whose first anthropometric measurements were made. IBM SPSS 22 package program was used in the statistical evaluations of the data. During the 8-week period, the study group students (10 girls-10 boys) had one hour of training with the Yellow Cards section of the Physical Activity Cards two days a week (Tuesday-Friday). The data was evaluated by taking the post-test data at the end of 8 weeks. Results: When the scores of the students in the Child Body Coordination test were evaluated, it was determined that the performances of the students in the study group were significantly different compared to the control group (p < 0.05). This difference was observed in both male and female students. A significant increase was recorded in the total scores of the male students in the study group, and according to the post-test results, the average score of the male students in the study group was measured as 203.90±30.17. In contrast, the post-test average score of the male students in the control group was determined as 141.40±43.79. This result shows that there was a significant improvement in the coordination levels of the male students in the study group. Similarly, a remarkable increase was also observed in the total scores of the female students in the study group. While the post-test average score of the female students in the study group was 188.00±25.39, the average score of the female students in the control group was calculated as 162.50±22.70. This finding shows that the practices of the study group were effective in developing coordination skills in female students as well. In general, it was revealed that there was a statistically significant difference between the study group and the control group in terms of the total scores of the Child Body Coordination test (p < 0.05). The results obtained show that the methods applied in the study group were effective in developing the coordination skills of children and that this effect provided significant improvement in both male and female students. Conclusion: It was concluded that the basic movement skill practices performed with Physical Activity Cards were effective in developing the body coordination of primary school students between the ages of 7-10 and that this effect provided a significant difference in favor of the study group (p < 0.05)
