Psychological adjustment in children and fencing: A descriptive research: Çocuklarda ruhsal uyum ve eskrim sporu: Betimsel bir araştırma
The aim of research is describe the psychological adjustment levels of fencing students at ages 6-11 through their parents and teachers. 42 male and 38 female fencing students participated in the research. In order to determine the psychological adjustment level of the participants, a personal information form and Hacettepe Psychological Adjustment Scale filled out by the parents and teachers. Descriptive statistics, Pearson correlation and Mann Whitney-U analysis were applied to the data set. As a result of the analyzes, it was found that there was a negative correlation between sport age and psychological maladjustment levels (p <0.05). It is thought that fencing positively affect children’s psychological adjustment level. However, there was a significant difference between parent and teacher evaluations (p <0.05). It can be mentioned that teachers see children more flawlessly and in harmony while evaluating, or that children exhibit behavioral problems in the school environment at a lower rate than in the home environment. It is thought that the obtained data can be a guide resource for longitudinal and experimental studies to be conducted on the potential of fencing sports to effect the psychological adjustment levels of children.

Özet
Araştırmanın amacı, 6-11 yaş aralığında eskrim sporu yapan çocukların nevrotik ve davranış sorun boyutları ile bunların bileşkesi olan ruhsal uyum düzeylerini, ortaya koymaktır. Araştırmaya eskrim sporu yapan 42 erkek ve 38 kız çocuk katılmıştır. Araştırmaya katılan sporcuların ruhsal uyum düzeylerini belirlemek amacıyla ebeveyn ve öğretmenlerine kişisel bilgi formu ve Hacettepe Ruhsal Uyum Ölçeği uygulanmıştır. Elde edilen veri setine, tanımlayıcı istatistikler, Pearson kolerasyon çarpımı ve Mann Whitney-U analizleri uygulanmıştır. Yapılan analizler sonucunda, spor yaşı ile ruhsal uyumsuzluk düzeyleri arasında negatif yönde orta düzeyde ilişki olduğu tespit edilmiştir (p<0,05). Eskrim sporunun çocukların ruhsal uyum düzeylerini olumlu yönde etkilediği düşünülmektedir. Bununla birlikte ebeveyn ve öğretmen değerlendirmeleri arasında ise anlamlı farklılık olduğu saptanmıştır (p<0,05). Öğretmenlerin değerlendirme yaparken çocukları daha kusursuz ve uyumlu gördükleri veya çocukların okul ortamında davranış sorunlarını ev ortamına göre daha düşük oranda sergilediklerinden söz edilebilir. Elde edilen verilerin, eskrim sporunun çocukların ruhsal uyum düzeylerini etkileme potansiyeli ile ilgili yapılacak olan boylamsal ve deneysel çalışmalara bir fikir kaynağı olabileceği düşünülmektedir
A Rare Cutaneous Adnexal Tumor: Malignant Proliferating Trichilemmal Tumor
Proliferating trichilemmal tumors (PTTs) are neoplasms derived from the outer root sheath of the hair follicle. These tumors, which commonly affect the scalp of elderly women, rarely demonstrate malignant transformation. Although invasion of the tumors into neighboring tissues and being accompanied with anaplasia and necrosis are accepted as findings of malignancy, histological features may not always be sufficient to identify these tumors. The clinical behavior of the tumor may be incompatible with its histological characteristics. Squamous-cell carcinoma should certainly be considered in differential diagnosis because of its similarity in morphological appearance with PTT. Immunostaining for CD34, P53, and Ki-67 is a useful adjuvant diagnostic method that can be used in differential diagnosis aside from morphological findings. In this study, we aimed to present the case of a 52-year-old female patient with clinicopathological features. We reported a low-grade malignant proliferating trichilemmal tumor in this patient and detected no relapse or metastasis in a 24-month period of follow-up
Design optimisation of Propeller Boss Cap Fins for enhanced propeller performance
Economic pressures and regulatory requirements have brought about a great interest in improving ship propulsion efficiency. This can be exercised by installing Energy Saving Devices (ESD) such as Propeller Boss Cap Fins (PBCF). This paper demonstrates an approach for optimising PBCF by using Computational Fluid Dynamics (CFD) analysis. The conducted Reynolds-averaged Navier-Stokes (RANS) CFD open water model tests were validated by comparison with experimental data until the simulation was deemed satisfactory within the capabilities and limitations of the model. A design and optimisation procedure was defined to analyse the impact of ESDs on propeller efficiency and then used to evaluate the influence of alternative geometric parameters and locations of the PBCF on the hub. This analysis was done at full scale using high fidelity CFD-based RANS methods. Outcomes of the study include a design and optimisation process that can be used for the analysis of other ESDs on the market. The influences of various PBCF geometry were examined with optimal solutions presented for the analysis case. Results indicated a net energy efficiency improvement of 1.3% contributing to a substantial minimisation of cost and energy consumption. A reduction in the hub vortex was also clearly identified and presented
Effect of Pterygium Surgery on Tear Osmolarity
Purpose. To investigate changes of dry eye test results in patients who underwent pterygium surgery. Methods. Seventy-four patients who underwent primary pterygium surgery were enrolled in this study. At the baseline, 3-, 12-, and 18-month visits, measurements of tear osmolarity, BUT, and Schirmer test were performed. The patients were divided into 2 groups: Group 1, which consisted of patients in whom pterygium did not recur, and Group 2, which consisted of patients in whom pterygium recurred after surgery. Results. The patients in Group 1 had lower tear osmolarity levels after surgery than those at baseline (all P0.05). Conclusions. Anormal tear film function associated with pterygium. Pterygium excision improved tear osmolarity and tear film function. However, tear osmolarity deteriorated again with the recurrence of pterygium
Dualism in Labor Market: The Case of the Financial Sector in Turkey
Dual labor market hypothesis developed in the 1960s asserts that labor markets consist of primary markets with good conditions in respect to earnings, promotion and working conditions and secondary markets with low yield, poor working conditions and low unionization and insurance coverage. Human capital investments yield high-yield in the primary markets with qualified jobs and yield of the human capital investments are low in secondary jobs for the reason that they require fewer qualifications. The studies to date from that period show that differences in labor market have not disappeared with the competitive operation of market mechanism as claimed by orthodox theory, but have further deepened. In this study, earnings and income differences between three groups involved in the financial markets under criteria of The Statistical Classification of Economic Activities in the European Community (NACE Rev.2) are examined within the scope of the dual labor market theory. According to Household Labor Force Survey data of 1504 financial employee data, the existence of two separate markets, which have statistically significant differences in terms of earnings, education and social security, is revealed
AN AUTOMATED COMPUTER-AIDED DETECTION (CADe) AND DIAGNOSIS (CADx) SYSTEM FOR BREAST MICROCALCIFICATIONS IN MAMMOGRAMS
ABSTRACTAn automated computer aided diagnosis system has been proposed for detection of microcalcification (MC) clusters in mammograms. The proposed system is a whole system including suspicious regions identification, MCs detection, false positive reduction and benign/malign classification. For classification of suspicious microcalcification regions, a multilayer perceptron (MLP) neural network was used with grey level co-occurrence matrix (GLCM) and statistical features. Then to decrease the false positive classification ratio, we used cascade correlation neural network (CCNN) with grey level run length matrix (GLRLM) features. In the last step, hybrid form of discriminant analysis and support vector machine (SVM) methods were used with GLRLM features for benign/malign classification of detected MC clusters. The open access Mammographic Image Analysis Society (MIAS) database was used for the study. Experimental results show that the proposed algorithm obtained 86% sensitivity, 98.3% specificity and 1.163 FPpI rates for detection an for diagnosis of breast cancer, the obtained sensitivity and specificity values are 100% and 100% respectively. Despite the vision difficulty of MC clusters, the novel system provides very satisfactory results. Furthermore, the developed system is fully automatic whole system which gives outputs as percentages and transformed assessment categories. Keywords: Mammograms, Breast cancer, Computer aided diagnosis, Cascade correlation neural network (CCNN), Grey level co-occurrence matrix (GLCM), Grey level run length matrix (GLRLM).

Functionalized graphitic carbon nitrides for environmental and sensing applications
Graphitic carbon nitride (g-C3N4) is a metal-free semiconductor that has been widely regarded as a promising candidate for sustainable energy production or storage. In recent years, g-C3N4 has become the center of attention by virtue of its impressive properties, such as being inexpensive, easily fabricable, nontoxic, highly stable, and environment friendly. Herein, the recent research developments related to g-C3N4 are outlined, which sheds light on its future prospective. Various synthetic methods and their impact on the properties of g-C3N4 are detailed, along with discussion on frequently used characterization methods. Different approaches for g-C3N4 surface functionalization, mainly categorized under covalent and noncovalent strategies, are outlined. Moreover, the processing methods of g-C3N4, such as g-C3N4-based thin films, hierarchical, and hybrid structures, are explored. Next, compared with the extensively studied energy-related applications of the modified g-C(3)N(4)s, relatively less-examined areas, such as environmental and sensing, are presented. By highlighting the strong potential of these materials and the existing research gaps, new researchers are encouraged to produce functional g-C3N4-based materials using diverse surface modification and processing routes.UK Research & Innovation (UKRI) Engineering & Physical Sciences Research Council (EPSRC) ; Royal Society-Newton Advanced Fellowship Grant ; Leverhulme Trus
