EXPERIENCE IN USING DISTANCE LEARNING TOOLS IN PROFESSIONAL DEVELOPMENT PEDAGOGICAL CORPS
The article presents and describes a tool for the professional development of teachers. Special attention is paid to the subject-methodical section, the implementation of which since 2020 has been taking place in an online form with the use of distance educational technologies. The article describes and presents the concepts of «e-learning» and «distance learning technologies,» and briefly presents the history of the development of distance education in the world. The article contains a description of the advantages of distance learning, as well as an analysis of the difficulties experienced by students of training courses and seminars, and advanced training of distance courses. In the post-industrial world, one of the main qualification requirements is professional mobility, determined by readiness for continuous retraining and advanced training. The education system, designed to ensure the increase of human capital, and increase the efficiency and competitiveness of the economy, should, first of all, prepare people for life in rapidly changing conditions. Therefore, the system itself must keep up with the changes taking place. The main challenge of 2020 was the emergency transfer of the educational process to a remote form using e-learning technologies. The education system did not have time to «group up» and prepare. The implementation of educational programs in a remote format required careful coordination of pedagogical activities and thoughtful administration of the process. The crisis exposed serious substantive and organizational problems in the industry and identified professional-pedagogical difficulties in the field of ICT competence: both at the level of the general user and the level of the general pedagogical component. The pedagogical community has an objective need to master new competencies. We can assume that the current situation will inevitably entail changes in the standards of training and retraining, as well as the emergence of new training programs
Bit-Serial Multiplier for FPGA Applications
A Field-Programmable Gate Array (FPGA) implementation of a multiplier topology can provide a considerable increase in computation performance and cost benefit as compared to other approaches, particularly for large bit widths ( e.g., for multiplication of large-bit numbers). A lack of sufficient input/output (I/O) ports on the FPGA for a particular bit width can be remedied by implementing large-bit number multiplications in a bit-serial fashion. The bit-serial multiplier topologies described herein can provide a relatively small footprint as compared to other approaches. An FPGA-implemented bit-serial multiplier can improve operation of a computing system, for example, by offloading binary multiplication operations from a general-purpose processor

A review of levosimendan in the treatment of heart failure
Heart failure is a relatively important public health problem due to its increasing incidence, poor prognosis, and frequent need of re-hospitalization. Intravenous positive inotropic agents play an important role in treating acute decompensation of patients with heart failure due to left ventricular systolic dysfunction. Although frequently used, the inotropic agents β-adrenergic agonists and phosphodiesterase inhibitors seem effective for improving symptoms in the short term; it has been shown that they increase morbidity and mortality by elevating intracellular cyclic adenosine monophosphate (cAMP) and calcium levels. Levosimendan is a new positive inotropic agent having ATP-dependent potassium-channel-opening and calcium-sensitizing effects. In studies on its effects without increasing intracellular calcium concentrations and on its effects that depend on available intracellular calcium levels, it has been shown to have favorable characteristics different from those of current inotropic agents, which exert their effects by increasing calcium concentrations. This study aims to review other important studies about levosimendan by revealing the underlying mechanisms of its activity, efficiency, and safety
Impact of marbling art therapy activities on the anxiety levels of psychiatric patients
Purpose: Study was conducted to explore the impact of marbling art therapy on the anxiety levels of patients with schizophrenia and bipolar disorder.Methods: Data for the study were at a university hospital and in the psychiatric service,polyclinic of a State Hospital with 34 patients diagnosed with schizophrenia and 34 patients diagnosed with bipolar disorder. Investigations were carried out with study groups and a control group.Findings:Following marbling, it was found that there were significant decreases in the PANSS negative, in the positive, general psychopathology in terms of the scores of the group of schizophrenia patients and in the BAI scores of patients with bipolar disorder.There was no significant difference in the BAI scores of the control group.Clinical relevance:The study showed that the method of marbling therapy led to improvements in the negative and positive symptoms of schizophrenic patients and in both patient groups, it contributed to decreasing levels of anxiety
Edge detection of aerial images using artificial bee colony algorithm
Edge detection techniques are the one of the best popular and significant implementation areas of the image processing. Moreover, image processing is very widely used in so many fields. Therefore, lots of methods are used in the development and the developed studies provide a variety of solutions to problems of computer vision systems. In many studies, metaheuristic algorithms have been used for obtaining better results. In this paper, aerial images are used for edge information extraction by using Artificial Bee Colony (ABC) Optimization Algorithm. Procedures were performed on gray scale aerial images which are taken from RADIUS/DARPA-IU Fort Hood database. Initially bee colony size was specified according to sizes of images. Then a threshold value was set for each image, which related with images’ standard deviation of gray scale values. After the bees were distributed, fitness values and probability values were computed according to gray scale value. While appropriate pixels were specified, the other ones were being abandoned and labeled as banned pixels therefore bees never located on these pixels again. So the edges were found without the need to examine all pixels in the image. Our improved method’s results are compared with other results found in the literature according to detection error and similarity calculations’. All the experimental results show that ABC can be used for obtaining edge information from images.Publisher's Versio
Study of health care providers and attitudes against homosexual, bisexual individuals
The present study was carried out in order to examine the attitudes of health care providers and of homosexual and bisexual individuals towards gays.The study, which was contemplated as descriptive and a correlation research, was carried out with 294 individuals who applied to the Lambda and Kaos GL Associations, and 261 health care providers employed at the Bülent Ecevit Üniversitesi Uygulama ve Araştırma Hastanesi (Bülent Ecevit University Application and Research Hospital).The study was carried out between October 2010 and February 2011. The data were collected through “Homosexuality Attitudes Scale”, “The Attitudes Towards Lesbians and Gay Men Scale” via “Socio-demographical Information Form Addressed Towards LGBTT Individuals” and “Socio-demographical Information Form Addressed Towards Health Providers Employed at the Hospital”. It was determined that married health providers; those thinking homosexuality/bisexuality is a disease or a disorder (p=0,002); and those who do not have a homosexual/bisexual member in their families (p=0.022) tend to be more homophobic; it was also observed that, married LGBTT individuals (p=0.036); LGBTT individuals working in the public sector, are self-employed or business owners (p=0.00); and LGBTT individuals who are “always” timid of being homosexual/bisexual (p=0.00), tend to be more homophobic.We found that not knowing any homosexual individuals, being married and thinking that homosexuality is a disease were effective in the development of negative attitudes towards LGBTT individuals

Comparison of growth, carcass and meat quality characteristics of triploid and diploid Black Sea trout (Salmo trutta labrax) under laboratory conditions
This study compared the growth performance of triploid and diploid Black Sea trout (Salmo trutta labrax) during their fry (initial weight 0.21 - 0.21 g), fingerling (1.97 - 2.08 g) and juvenile (52.15 - 57.81 g) stages. The carcass ratio, gonadosomatic index (GSI), hepatosomatic index (HSI), proximate, and fatty acid composition for the juvenile fish were also investigated. The results evinced no metabolic advantage resulting from triploidy before sexual maturation of Black Sea trout as the triploid growth was equal to diploid siblings. The juvenile triploid Black Sea trout grew faster than diploid having significantly higher weight gain, length increment, thermal growth coefficient, specific growth rate, and lower feed conversion ratio. The GSI values tended to increase over time in diploid and their significantly lower values were observed in triploid in the last three months of the trial. The HSI of triploids was significantly higher than diploid siblings. Triploid had significantly higher fat contents, and possessed higher levels of saturated and monounsaturated fatty acids than diploid. Diploid had higher polyunsaturated fatty acids than triploid siblings. These findings indicate the potential for superior triploid growth with better carcass ratio suggesting a great benefit of induced triploidy in Black Sea trout culture
The Potential of Solar Air Heating in the Turkish Industrial Sector
Transpired solar collector (TSC) systems are simple solutions for the preheating of ventilation air with solar energy. Their performance is a function of several environmental factors, so the climatic conditions of the location play an important role. In this paper, the effect of different climatic zones on the thermal performance of the TSC is investigated. To exclude other sources of influence, the same reference industrial building is examined in four Turkish locations (Antalya, Istanbul, Ankara and Sivas) representing different climatic conditions. RETScreen simulation is carried out for all four regions to obtain the drop of conventional heating requirement in case absorber azimuth of 0°, 45° and 90°. To illustrate the performance, temperature rise, heating energy savings and annual solar fraction are presented. Generally, it can be stated that a location with cold climate and high solar radiation at the same time benefits most from the use of a TSC system. A mathematical correlation has been found showing the solar fraction's dependence on solar radiation and heating degree days. Finally, simulation results have been compared to a set of measurement data from an industrial building's TSC system near Istanbul
