In this study, it was aimed to examine the social anxiety levels of students studying in sports and music departments. The study group consists of students (n=180) studying at the State Conservatory and Sarıkamış High School of Physical Education and Sports affiliated to Kafkas University in the 2021-2022 academic year. The general screening and causal comparison approach form the basis for the study. “Personal Information Form” and “Social Anxiety Scale” were used as data collection tools. Analysis of the data was performed with the help of Independent t-Test and One-way analysis of variance (ANOVA). As a result, it has been determined that the social anxiety levels of the students studying in sports and music departments vary according to gender, but there is no significant difference according to variables such as income level, class and department.
The present research aims to adapt the Body Understanding Measure for Pregnancy Scale (BUMPs) to Turkish, determine its psychometric properties, and examine the correlation between prenatal ...attachment and body image perception of pregnant women.
Three hundred seventy-one pregnant women were enrolled in the research. The original English version of the BUMPs was translated into Turkish using forward-backward translation logic. The scale's reliability was evaluated with item analysis, internal consistency analysis, and test-retest reliability. Turkish version of the BUMPs and Prenatal Attachment Inventory (PAI) were filled out by pregnant women. The relationship between them was evaluated by correlation analysis.
The mean week of gestation was 25.25 ± 8.26 (min: 12, max: 41). The Turkish version of the BUMPs exhibited satisfactory psychometric properties. The t-values, factor loadings, and fit indices of the scale items of the Turkish version were at an acceptable and excellent level. As a result of confirmatory factor analysis, the 18-item, three-factor construct was confirmed for the Turkish version of the scale. In the Turkish version of the scale, there are three subscales, including satisfaction with appearing pregnant, weight gain concerns, and physical burdens of pregnancy. Cronbach's alpha internal consistency coefficient of the overall scale was 0.84. A significant correlation was determined between the scores of the Turkish version of the BUMPs and the PAI (r = −0.263; p < 0.001).
The Turkish version of the BUMPs is a valid and reliable measurement tool for determining pregnant women's body image perception. Prenatal attachment increases with the increasing body image perception of pregnant women.

The fact that there are no real borders between the biosphere, atmosphere, lithosphere, and hydrosphere means that environmental pollution monitoring studies should not only include one of the ...environmental spheres. Thus, integrated environmental pollution assessment studies conducted in the biosphere, lithosphere, and atmosphere promote the “whole system” approach. In this study, the aim was to determine the pollution in the atmosphere, soil, and plants by taking advantage of the high pollution accumulation characteristics of the mosses. Prevailing wind has the potential to distribute pollutants emitted into the air throughout its path. With this regard, soil, mosses, and atmospheric deposition samples were collected in Çanakkale, Turkey, in two seasons. Concentrations of selected elements were measured by Inductively Coupled Plasma-Mass Spectrometry. The enrichment factor of the selected elements in the soil, moss, and deposition samples was calculated. The highest enrichments were found for Lead in atmospheric deposition, Arsenic in soil, and Mercury in moss samples. Cobalt and chromium accumulated more in mosses than in soil. Elevated arsenic levels found in the samples can pose a great risk for public health and agriculture. The study result showed that the elemental composition of the samples was influenced by the enhanced air plume dispersion of anthropogenic pollution sources along the Northeast-Southwest directions due to wind characteristics in the province. As expected, strong correlations were found among the moss, soil, and atmospheric deposition samples indicating the vital interactions between the environmental components.
Objectives
The aim of the study was to investigate the impact of stage‐grade of periodontitis and self‐reported signs and symptoms on oral health‐related quality of life.
Methods
The diagnosis of ...periodontitis was based on the 2017 World Workshop on the Classification of Periodontal and Peri‐Implant Diseases and Conditions. The Turkish version of Oral Health Impact Profile‐14 (OHIP‐14) was used to assess oral health‐related quality of life (OHRQoL) and the participants were requested to state their symptoms associated with periodontal diseases.
Results
One hundred and sixty‐six patients were included in the study with a mean age of 46.54 ± 9.24 years. The participants with Stage IV and Grade C periodontitis had the highest total OHIP‐14 scores (median 20.00 min.‐max, 3.00–35.00 and median 18.50 (min.‐max, 0.00–36.00; respectively). The OHIP‐14 scores (mean ± SD) were significantly associated with the symptoms of bleeding gums (13.64 ± 9.39), sore gums (18.00 ± 10.47), swollen gums (17.42 ± 10.91), bad breath (15.82 ± 9.44), loose teeth (20.00 ± 8.66) and drifting teeth (24.56 ± 8.46).
Conclusions
This study demonstrates a significant association between OHRQoL and periodontitis. Stage‐grade of periodontitis and its symptoms were associated with poor quality of life.
This paper presents the preliminary results of a numerical study for noise prediction of a benchmark propeller in open water/uniform flow conditions. The experimental benchmark test data for the ...research vessel, “The Princess Royal”, were used for validation purposes. The numerical analyses were implemented by using a viscous solver based on the finite volume method while the experimental data were obtained from model tests conducted at the Genova University Cavitation Tunnel. The main aim of the study is to predict propeller hydro-acoustic performance under cavitating conditions. The hydrodynamic flow field was solved using a RANS (Reynolds-averaged Navier-Stokes) solver. The Schnerr-Sauer cavitation model based on a reduced Rayleigh-Plesset equation together with a VOF approach was used to model sheet cavitation on the propeller blades. The computed hydrodynamic characteristics and sheet cavity patterns were shown to be in good agreement with the Genoa experimental data, thus providing a firm basis for cavitating noise predictions. The hydro-acoustic performance of the model propeller was predicted by using a hybrid method. In the noise simulations, RANS equations were equipped with a porous FW-H (Ffowcs Williams-Hawkings) formulation. The different propeller operational conditions were simulated using this hybrid method. The numerical results were also validated with the experimental data for the propeller hydro-acoustic performance. Whereas such validations showed promising results by means of overall noise spectrum with the benchmark test cases in the low-frequency range, the numerical prediction overestimated the 1st BPF values (around 20 dB) in five loading conditions. Besides, in some loading conditions, especially between 200 and 800 Hz, the difference between numerical predictions and the experiment was found around 5–10 dB.
•The first numerical underwater radiated noise results of benchmark propeller are presented.•RANS based acoustic analogy method can be used to predict the underwater radiated noise in the low-frequency region.•The numerical hydroacoustic results are quite good agreement with the experiment in the low-frequency region.•RANS method can be used as a reliable tool for the sheet cavitation modelling.
This paper presents the investigation of propeller-rudder-hull interaction by using Computational Fluid Dynamics (CFD), and Experimental Fluid Dynamics (EFD) approaches including the propeller's ...performance in cavitating conditions, particularly the effect of the tip vortex cavitation on the interaction phenomenon. The investigation was focused on the recently generated benchmark test data for the research catamaran, The Princess Royal, and its scaled model which was tested for cavitation and noise investigations in the large circulating water channel of CNR-INM, Italy within the scope of the European collaborative project. The propeller-rudder-hull interaction of a 1/3.4 scaled model of this vessel was simulated by using the commercial CFD software, STAR-CCM+, which implemented the Schnerr–Sauer cavitation model for the cavitation effect. Large Eddy Simulations (LES) was used for a better resolution of high velocity and pressure gradients to model the tip vortex cavitation. A new adaptive meshing technique using a Mesh Adoption Refinement Approach for Cavitation Simulations (MARCS) was applied for more effective modelling of the tip vortex cavitation during the propeller-rudder-hull interaction. The results of the CFD simulations were compared with the EFD data, particularly for the cavitation dynamics.

The purpose of this comprehensive research is to observe the impact of scintillator crystal type on entire detection process. For this aim, MCNPX (version 2.6.0) is used for designing of a physical ...plastic scintillation detector available in our laboratory. The modelled detector structure is validated using previous studies in the literature. Next, different types of plastic scintillation crystals were assessed in the same geometry. Several fundamental detector properties are determined for six different plastic scintillation crystals. Additionally, the deposited energy quantities were computed using the MCNPX code. Although six scintillation crystals have comparable compositions, the findings clearly indicate that the crystal composed of PVT 80% + PPO 20% has superior counting and detecting characteristics when compared to the other crystals investigated. Moreover, it is observed that the highest deposited energy amount, which is a result of the highest collision number in the crystal volume, corresponds to a PVT 80% + PPO 20% crystal. Despite the fact that plastic detector crystals have similar chemical structures, this study found that performing advanced Monte Carlo simulations on the detection discrepancies within the structures can aid in the development of the most effective spectroscopy procedures by ensuring maximum efficiency prior to and during use.
There is still no approved pharmacotherapy for metabolic (dysfunction) associated fatty liver disease (MAFLD). Although dietary and lifestyle modifications for weight loss remain the mainstay for ...disease management, the association between macro- and micronutrients and fibrosis stage in patients with MAFLD remains unclear. This study was undertaken to address this issue.
This is a retrospective analysis of prospectively collected data from patients in whom MAFLD was diagnosed with vibration controlled transient elastography. Steatosis was defined by a controlled attenuation parameter ≥238 dB/m, whereas a liver stiffness measurement ≥11 kPa was considered to indicate advanced fibrosis.
The study sample consisted of 106 patients with MAFLD (mean age 49 ± 10 years, 52 men and 54 women). Among the different micro- and macronutrients tested, only the dietary intake of cholesterol and saturated fatty acid (SFA) was independently associated with the presence of advanced fibrosis.
Our findings suggest that cholesterol/SFA-restricted dietary regimens - as exemplified by the traditional Mediterranean diet - may reduce the risk of advanced fibrosis in patients with MAFLD.
Bu çalışmada subasar ormanlarda odun hammaddesi üretim faaliyetleri, bazı teknik ve çevresel yönlerden incelenmiştir. Çalışma alanı olarak Hendek Orman İşletme Müdürlüğü’ne bağlı Süleymaniye Orman ...İşletme Şefliği’nde bulunan subasar ormanlar seçilmiştir. Çalışma alanında kesim, bölmeden çıkarma ve uzak nakliyat işleri teknik ve çevresel yönlerden incelenmiştir. Çalışma sonucunda; üretim zamanının, su basması nedeniyle kısıtlı olduğu, az miktarda yağışlı dönemde dahi üretime engel olacak seviyede suyun toprak yüzeyinde bulunduğu ve hatta ağaç damgalama dönemi olan Ocak-Nisan ayları arasında suyun 1-1,5 m yükseldiği belirtilmiştir. Ayrıca kesim ve bölmeden çıkarma işlemini gerçekleştirebilmek için alanda büz yerleştirerek drenajın yapıldığı gözlemlenmiştir. Sahada toplam 32 sefer bölmeden çıkarma işlemi incelenmiştir. İnceleme sonucunda, arazi eğiminin düz ya da düze yakın olması ve piyasa talepleri nedeniyle üretim metodu olarak bütün gövde metodu kullanıldığı belirlenmiştir. Çalışma alanında su basması ortalama 50 cm seviyesinde tespit edilmiştir. Subasar ormanlarda en önemli problemin toprak yüzeyinde biriken ve yükselen suyun olduğu tespit edilmiştir. Bu tür alanların toprak tipi genelde balçıklı olduğundan, bölmeden çıkarma için zemine daha iyi tutunan geniş lastikli traktörler kullanılmalıdır.
In this study, wood raw material production in forested wetlands was investigated from some technical and environmental aspects. Forested wetlands in the Süleymaniye Forestry Operations Directorate, which is affiliated with the Hendek Forestry Management Directorate, were chosen as the study area. In the study area, logging works were examined. In the results of the study, it has been determined that the production time is limited due to flooding and that there is water on the soil surface at a level that will prevent production even in a small amount of rainy period. It was even stated that the water rose 1-1.5 m between January and April, which is the tree marking period. In addition, it was observed that drainage was made in the area in order to perform the logging process. A total of 32 extractions were examined in the field. As a result of the examination, it was determined that the slope of the land was flat or almost flat and that the whole stem logging method was used as the production method due to market demands. In the study area, the flooding was determined at an average level of 50 cm. It has been determined that the most important problem in forested wetlands is the water accumulating and rising on the soil surface. Since the soil type of such areas is generally loamy, tractors with wide tires should be used for extraction from the compartment.
