Investigating Turkey High school Graduates’ Attitudes towards Technology

Procedia - Social and Behavioral Sciences 2015年 191卷 1416-1422页

computers have been integrated into almost all areas of our daily lives. Serious problems stem from the fact that elementary and secondary school students in general have taken none or inadequate computer classes and as such, their awareness of efficient computer usage has not been adequately addressed. During university education, students have been observed experiencing hardships using computers for research and document preparation, due to their prior use of computers having consisted mostly of accessing social media and games. The current study investigated 2013-2014 high school graduates’ attitudes regarding technology, the computer programs they used and their usage frequency, reasons for why they use the Internet and social media and their usage frequencies, and their basic computer skills at university level. The participants of the current study were students who had just entered various departments and language preparation levels at Fatih University, Istanbul, Turkey. 250 Participants were randomly selected. Data for the current study were collected through a Basic computer Skills Questionnaire, an application for determining the levels of participants’ basic computer skills. Significant benefits are foreseen for students entering universities as helpful computer users with awareness attained during elementary or secondary education. Additionally, particularly for students who prefer non-social majors, it will be very useful to have learned a programming language and an algorithm at basic levels. The Internet as a medium for potentially leading to a diverse range of problems today requires conscious users.

作者： Söylemez, Dilek Ankara University Elmadag Vocational School Department of Computer Programming Ankara 06780 Turkey

Sequence of q -Bleimann, Butzer, and Hahn operators which is based on a continuously differentiable function τ on R +, with τ 0 = 0, inf τ ' x ≥ 1, has been considered. Uniform approximation by such a sequence has been studied and degree of approximation by the operators has been obtained. Moreover, shape preserving properties of the sequence of operators have been investigated. © 2015 Dilek Söylemez.

In this paper, 2-steps software using image processing and enhancement technologies is developed to obtain a scoliosis patient's spine pattern from 2D coronal X-Ray images without manual land marking. Then, a Rule-based Fuzzy classifier is implemented on those images to classify the spine patterns using the King-Moe classification approach. © 2014 - IOS Press and the authors.

In this study, propagation prediction models based on ray tracing in coverage estimation for broadcasting systems are compared with respect to computation time and accuracy. Uniform Theory of Diffraction (UTD), Slope Diffraction (S-UTD) and Slope UTD with Convex Hull (S-UTD-CH) models are compared for computation time and propagation path loss. Moreover in this study, effects of transmitter height to relative path loss at the receiver are analyzed. S-UTD-CH model is optimum model with respect to computation time and relative path loss.

Optical character recognition(OCR) can be used in some management mechanisms of state and business world to organize documents scanned or captured by camera. Therefore, OCR is one of the subjects rapidly evolving in the recent times. This study investigates the procedure steps until character recognition. That's because, the more correctly preprocessings are applied;the better results can be obtained in character recognition. In this study, the algorithms providing the best results are determined by following the procedure stages of gray scale transformation, noise removal and image thresholding. Binarization plays an important role in character recognition. For this reason, algorithms dynamically determine thresholds are preferred for character recognition in this study. Accordingly, Otsu thresholding method was determined to give the best results in terms of both picture quality and speed. Therefore, this method was used for character recognition. Primarily, lines were determined for character separation and then letters were individually obtained.

Monte Carlo Simulation to Investigate the Cascade Transition of a Permuted Polyelectrolyte Chain

引用

Procedia computer Science 2012年 9卷 634-640页

作者： Sahin Uyaver Computer Programming Department Vocational School Istanbul Commerce University Istanbul Turkey

Using Monte Carlo simulations, the cascade transition of a single polyelectrolyte chain having permuted charge distribution is investigated. The polyelectrolyte chain is simulated at various solvent regimes. The effect of the electrostatic interaction strength is studied. The structures are analyzed with respect to the scaling laws. The effect of permuted charge distribution is investigated in comparison to the other charge distribution in the literature.

For drawing electrical wiring diagram of buildings, mostly two dimensional CAD programs are used. Drawing is done starting from the source (utility pole) to main power panel and then it is distributed towards to subpanels. Then, end points such as sockets, lighting armature, etc are defined. In this study several algorithms are developed in order to evaluate different part of drawing project. Tree structure of drawing is analyzed and all materials to be used are decided based on an algorithm. Apart from these, some of the supplies to be used in project but not shown in the drawings are also be chosen with certain criteria. These decision systems will result in efficiency of overall cost of the project. In wire drawing one of the most important point is the line drawing with reference to an object. Apart from light outlet all wires are referenced to walls. Furthermore, all supplies shown in drawings are allocated with reference to walls and with an angle to walls. In wiring diagram drawings, standard CAD programs have no ability for wire drawing with reference to walls. Besides that, suggestion and selection of the most appropriate supplies is not possible. These increase drawing time and result in very high cost calculation errors. These algorithms provide fast and correct implementation. By analyzing drawings in a tree structure on which users have minimal impact, and with automatic selection of supplies all type of calculation mistakes are minimized.

Liver is a vital organ of a body that has numerous functions. Severe malfunctioning of these functions causes a liver necrosis. The diagnosis of this necrosis is performed by a specialist who uses appropriate microscopic analysis. However, because this analysis is based on specialist's opinion, the results could be subjective and error prone. The aim of this study is to quantify the hepatic necrotic areas using computer aided algorithms and provide quantitative results that are not prone to errors. © 2012 IEEE.

Mathematical and Computational Applications 2012年第2期17卷 152-163页

Classical logic and classical set theorems are not sufficient enough when it is necessary to deal with complex decision making problems which also involve human experiences. Some researches suggest that senior management usually makes intuitive decisions in the process of selecting the candidates in political parties which brings out the need to derive a new efficient, robust and applicable method. In this study, the qualitative characteristics and their significance level which could be used for the candidate selection process in political parties are determined. The candidate selection process consisting vague inputs is analyzed by fuzzy logic methodology and a quantitative final score has been determined for the candidate. It has been shown that the model provided some realistic and promising results which could enable further studies to derive more optimized and enhanced models for similar purposes.
