Soygenc, Elcin Izmir; Onur, Ozge Sahmelikoglu
Objective: Growing evidence suggests that unipolar mania (UM) may represent a distinct clinical condition rather than a subtype of bipolar disorder (BD). The present study aimed to compare the sociodemographic characteristics, clinical features, and psychosocial functioning of euthymic patients with UM or bipolar I disorder (BD-I) and healthy control subjects. Method: This cross-sectional study included euthymic patients with UM (n=58), BD-I (n=58), and healthy control subjects (n=58). Diagnoses were established according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria, and euthymia was confirmed using the Young Mania Rating Scale, Beck Depression Inventory, and Positive and Negative Syndrome Scale. Psychosocial functioning was assessed using the Functioning Assessment Short Test (FAST) in all groups and the Bipolar Disorder Functioning Scale (BDFS) in the UM and BD-I groups. Sociodemographic and clinical data were collected using a structured form. Group comparisons were conducted using appropriate parametric and nonparametric statistical analyses. Results: Both patient groups demonstrated significantly impaired psychosocial functioning compared with healthy controls across all FAST subdomains (p<0.05). On the BDFS, patients with UM showed better emotional functioning and less social withdrawal than patients with BD-I (p<0.05); however, total functioning scores did not differ significantly between groups (p>0.05). Clinically, UM was characterized by manic-predominant onset, higher rates of mood-congruent psychotic symptoms, longer episode duration, and more frequent hospitalizations. Suicidal behavior and total number of mood episodes were higher among patients with BD-I (p<0.05). In the final logistic regression model, mood-congruent psychotic symptoms during the first episode were independently associated with UM relative to BD-I, whereas a history of suicide attempts was associated with lower odds of UM (p<0.05). Conclusion: Although both groups exhibited functional impairment, patients with UM demonstrated relatively better emotional and social functioning than those with BD-I. These findings suggest that UM may be associated with a distinct functional profile, with potential implications for prognosis and treatment planning. Incorporating functional outcomes into the clinical assessment of UM may help optimize therapeutic strategies and improve long-term psychosocial outcomes.

Durmaz, Mustafa; Daloglu, Ayse
In Turkey many roofs exposed to snow loads exceeding the design snow loads are damaged or collapsed. Roof snow load specified for structural design in Turkish codes is calculated as the product of a ground snow load multiplied by the conversion factors that depend on the roof properties. In this study, the ground snow loads in Turkish codes are evaluated via statistical analysis of Turkey snow data obtained from 92 Turkish State Meteorological Service stations. The probability plot correlation coefficient test for Gumbel, lognormal and Weibull distributions are used to determine the best fit of the probability distribution considering the snow data. 50-year design ground snow loads and snow depths of the stations determined by using the selected distributions are compared to those proposed in Turkish codes. It is concluded that TS 498 is unsafe for Eastern Black Sea and Eastern Anatolia regions and Gumbel distribution used in TS 7046 does not represent half of the snow data.

Dogan, Ramazan Ozgur; Türe, Hayati; Kayikçioglu, Temel
The pectoral muscle region on MLO mammography images appears prominently similar to suspicious areas. For this reason, Computer-Aided Detection (CAD) systems remove this region to reduce false-positive rates in the mass detection process. In some cases, the pectoral muscle region is exposed to distortions due to the superposition effects caused by the mammography technique. As a result, segmentation error rates of the pectoral muscle region, whose characteristic features are deteriorated, appear. In this study, a method to identify impaired pectoral muscle regions with MobileNetV2 backboned U-Net Deep Learning method is proposed. The proposed method was tested on 84 and 201 mammography images taken from both MIAS and InBreast databases and segmented with 1.81% and 1.92% false-negative (FN) and 0.25% and 0.37% false positive (FP) rates, respectively. Particularly for distorted pectoral muscle regions, the proposed method has been shown to outperform some pioneering studies in this area.

Gul, Fatih; Efeoglu, Hasan
In this study, a direct-current reactive sputtered AliZnO/Al-based memristor device was fabricated and its resistive switching (RS) characteristics investigated. The optical and structural properties were confirmed by using UV vis spectrophotometry and x-ray diffraction, respectively. The memristive and resistive switching characteristics were determined using time dependent current voltage (I-V-t) measurements. The typical pinched hysteresis I-V loops of a memristor were observed. In addition, the device showed forming-free, uniform and bipolar RS behavior. The low electric field region exhibited ohmic conduction, while the Schottky emission (SE) was found to be the dominant conduction mechanism in the high electric field region. A weak Poole-Frenkel (PF) emission also appeared. In conclusion, it was suggested that the SE and PF mechanisms were related to the oxygen vacancies in the ZnO. (C) 2016 Elsevier Ltd.

Çevik, Sibel; Çakmak, Recep; Altas, Ismail Hakk
The integration of renewable energy sources to the electrical grid leads to some issues in the grid because of intermittent and variable characteristics of renewable energy sources such as wind and solar. It has been predicted that the solar based electricity production will has highest annual increase rate among the other renewable sources. Due to the intermittent and volatile nature of the solar energy in an electricity grid where photovoltaic systems are intensive, load planning is essential. Therefore, day ahead solar radiation forecasting will contribute to the load planning studies. Artificial neural networks are one of the methods that are applied frequently and successfully in forecasting studies. In this study, a cause effect based artificial neural network (ANN) has been designed and performed for day ahead hourly solar radiation forecasting in Trabzon province. A similar day selection algorithm has been utilized to get more accurate forecasting by the ANN. The designed ANN has been trained and tested in MATLAB simulation environment without using ready codes of MATLAB ANN toolbox. The obtained results reveal that the designed ANN forecasts the solar radiation with acceptable error for a place such as Trabzon which has rainy and cloudy weather conditions.

Sipahi, Ferkan; Sadiklar, M. Burhan
The Late Cretaceous volcanic rocks around Zigana Mountain (Gumushane) in the eastern Black Sea metallogenic province in NE Turkey show intensive hydrothermal alteration but less weathering alteration. The basement of the study area is formed by Late Cretaceous basalt, andesite and their pyroclastics. These rocks are overlain by dacitic rocks of the same age, namely Dacite-I and Dacite-II. These volcanic rocks are bimodal in character and have developed in a volcanic arc environment. The volcanic rocks in the study area have been altered to the sericite/illite-chlorite facieses, and contain sericite/illite, chlorite, quartz, carbonate minerals (ankerite and calcite), iron-oxide, and rare kaolinite, smectite and epidote as the products of alteration. Sericitization/illitization is the most common type of hydrothermal alteration associated with these volcanics, and chloritization is the most common alteration type after illitization; pyritisation is seen in all volcanics, and is the most common in dacites. In some fields limonitisation is occasionally present. Epidotization is rare, and especially seen in basalt and andesite. Isocon analysis was undertaken to estimate the mass gains and losses of the Zigana Volcanics as a result of hydrothermal alteration. In general terms, the results shows that, basalt and andesite have 2-61% mass gain, Dacite-I 71% mass gain and 42 % mass loss, and Dacite-II 44% mass gain and 32% mass loss. Namely, both mass gain and mass loss occurred in the volcanics during the hydrothermal alteration of the parent materials. From less altered rock to highly altered rock there was an increase in illite-chlorite-kaolinite whereas there was a decrease in carbonate minerals. In the volcanics, fluids which cause sericitization and chloritization did not increase metals like Cu, Pb and Zn and, in fact, it can be said that these fluids are poor in point of these metals. This also shows that the metals developed under different hydrothermal conditions.

Qaddom, Mahmoud; Mohamed, Ali Abdelwahed Abdelhameed
Modern technology has become an auxiliary source in teaching languages and developing language basic skills: listening, speaking, reading and writing. Consequently, teachers, especially in the field of teaching Arabic to non-Arabic speakers, can not skip these technological methodsor ignore them in teaching and exercising language skills. The present research discusses the role of social media in teaching Arabic to non-Arabic speakers in Turkish public universities. Unlike previous studies which addressed the use of modern technology as a secondary consern in teaching arabic to non-native speakers, this research is one of the few studies thatbasically addresses this issue in this field. This study is dedicated to the study of the social media and its role in teaching Arabic to non-Arabic speakers in Turkish universities. It seeks to answer the following questions: What is the reality of the use of social media in teaching Arabic in Turkish universities? What is the effectiveness of the use of social media in the development of language skills among students of Turkish universities? What are the pros and cons of using social media sites in learning Arabic from the perspective of students and faculty teaching members in Turkish universities? We came into the following conclusions:All means of social media with all available channels contribute directly to the teaching of the Arabic language skills as well as overcoming a lot of mistakes committed by both teachers and learners of non-Arabic speakers.

Bas, Mustafa; Aydin, Elif
The study was carried out on a total of 260 secondary education students, 135 (51.9%) female and 125 (48.1%) male. As data collection tools in research, the Personal Information Form, the Physical Education Predisposition Scale and the Responsibility to Learn Scale were used. Considering the relationship between students' predispositions to physical education and their level of responsibility for learning, it was found that there was a positive significant relationship between the responsibility and the attitude and self-efficacy. Following the regression analysis a positive relationship between the students' level of responsibility for learning and their attitude and self-efficacy was found. In this context, it can be stated that as the students' levels of responsibility for learning increase, their level of predisposition to physical education also increases. The equation for students' levels of responsibility for learning to predict their predisposition to physical education is significant.
