Within FATİH Project, it's aimed to use information technology more effectively in learning environments and targeted to make technological infrastructure improvements in schools. For this process information technology teachers play a key role. Thus, Information Technologies (IT) pre-service teachers' computer self-efficiency perceptions were examined. In the study, a survey model was used and the sample included 200 Computer Education and Instructional Technologies (CEIT) students in two different universities. Relationships between the perceptions of computer self-efficacy of CEIT students and variables such as gender, graduated high school type, place of department preference, grade level and university type were examined by using computer self-efficacy scale that was developed by Orhan ve Akkoyunlu (2003). As a result, it's indicated that; Male pre-service teachers have higher computer self-efficacy perceptions than female pre-service teachers, Pre-service teachers ...

Web technology is changing rapidly every day and the Internet has become a lifestyle for people all over the world. It is obvious that the life style of societies is in a process of change, as new habits are acquired. Even though Internet use is one of the new social habits, it is one of the most important factors that induce this change as regards the convenience it brings to communication and other areas. The widespread use of Internet implies the idea that it can also be more widely used for educational purpose. Since chemistry teachers have a very important function in education, the determination of teachers ’ attitude towards Internet use is also important. In the literature it is possible to see many studies on teacher candidates ’ at-titude towards Internet use; however studies on appointed teachers ’ attitude are not very common. In our study, which aims to determine the attitude of appointed chemistry teachers according to different vari-ables, we used the Internet use att...

Knowledge networks can be defined as social networks that enable the transfer of the knowledge, which is defined as the intellectual product formed as a result of the work of human intelligence, to be transferred to any other means of communication. A knowledge network represents a large number of people, resources and relationships between them, to create the highest value, primarily to accumulate and use knowledge through the process of generating and transmitting knowledge. General structure of knowledge networks; it consists of three basic stages: gathering, organizing and disseminating knowledge. The first step, knowledge collection, institutions and organizations to enter the network structure of the knowledge that is present. The organizing phase is the structuring of irregular and unstructured knowledge in the network structure according to certain standards and recording them regularly in the structure. Knowledge dissemination can be expressed as the transfer of organized k...

Ad-hoc networks are temporary networks, which use wireless media that consists of interconnected nodes without a common network infrastructure using wireless media for immediate and dedicated network solutions. Ad-hoc networks are much vulnerable against the threats compared to the traditional networks due to its nature of lacking of a central control mechanism and the individual attitude of each node. In this study, the security threats and the routing protocols defined for ad hoc networks are investigated and the findings are evaluated. The aim of the study is to reach a generalized conclusion on the existing routing protocols in ad-hoc networks by evaluating the advantages and disadvantages of these protocols. In this paper, it is shown that the routing and security protocols to be used in ad-hoc networks should be designed by providing a resistance, robustness and high energy efficiency in order to overcome security treats aiming for confidentiality, integrity and accessibility....

The widespread use of internet implies the idea that it can also be more widely used for educational purposes. In this respect, since physics teachers have a very important function in education, to determine physics teachers’ attitudes towards internet use is also important. In the literature it is possible to see many studies on teacher candidates’ attitude towards internet use; “however studies on appointed teachers’ attitude are not very common. In our study, which aims to determine the attitude of appointed teachers according to different variables, we used the Internet Use Attitude Scale. For the teachers that took part in the study the attitude towards internet use was analyzed and interpreted according to the variables of gender, years on the job, type of school at which they are teaching, and duration of their weekly internet use. It was seen that a vast majority of the teachers have personal computers, they connect to internet at home and have positive attitude towards int...

Software development processes, in general, focus on organizing the order of the phases to develop the intended software product within time and cost constraints. However, the vulnerabilities of the software projects released to the market indicate the need of a security oriented software development process along with providing the time and cost criteria. Moreover, to our best knowledge, there exist some studies stating that the security activities in conventional software development contribute to the effectiveness in providing the security. However, if the agile software development processes are reviewed, it can be seen that principles of agile and security do not match at some points. At this point, the model of Trustworthy Scrum (TS) comes to prominence by enabling the security activities to cooperate with the agile methods and to work in Scrum framework. In this study, a statistical analysis related to the feasibility of the Trustworthy Scrum model was conducted in order to a...

In this study, elementary and high school students’ information and computer security awareness levels were investigated. Information and Computer Security Awareness Scale was developed by the researcher and it was applied to 2447 students in the schools in center of Kahramanmaras City, towns, small towns and villages of Kahramanmaras province. For data analysis the statistical analysis program was used. Consequently it was found that students have sufficient awareness level in terms of ethical issues. However, they have low awareness levels in terms of issues that require knowledge about rules. It can be deduced that information and computer security awareness education and related activities are insufficient. If these courses’ hours can be increased, students’ information and computer security awareness can be enhanced and negative effects of internet can be controlled.

Natural language is one of the most fundamental features that distinguish people from other living things and enable people to communicate each other. Language is a tool that enables people to express their feelings and thoughts and to transfers cultures through generations. Texts and audio are examples of natural language in daily life. In the natural language, many words disappear in time, on the other hand new words are derived. Therefore, while the process of natural language processing (NLP) is complex even for human, it is difficult to process in computer system. The area of linguistics examines how people use language. NLP, which requires the collaboration of linguists and computer scientists, plays an important role in human computer interaction. Studies in NLP have increased with the use of artificial intelligence technologies in the field of linguistics. With the deep learning methods which are one of the artificial intelligence study areas, platforms close to natural lang...

An initial design for a power circuit of a new plasma system is proposed and implemented in MatLab code. The plasma device is a torus and requires an excitement of wires, which are wrapped around the torus for a toroidal field and a poloidal field coil placed at the outer part of the device. This poloidal coil structure ignites an electrical field inside the chamber and that yields to a circular magnetic field inside the plasma. The proposed electrical design for this poloidal field equipment has some components including the alternating current unit and the direct current one. The circuit first uses an ac-dc converter, in order to transfer the ac grid to the dc one. Then it uses a switching scheme and a discharge circuit. The operation voltages for the poloidal field are estimated to be 1 kV, respectively. It has been proven that the designed system can produce an almost dc current with 66 V fluctuation, which is under the limit of 6%, considering the high voltage of 1kV.

Instructional models form based on the needs. To satisfy the needs specific targeted instructions are presented. Teaching how a vehicle is used, is an example for specific targeted courses. This study suggests and defines a new concept namely “integrated instructional material”. Integrated structures are applications and structures which contain integration for a specific purpose in a system approach. Accordingly, integrated instructional material is an assistant system for instruction. In other words, it is a supportive tool for teaching subjects of different disciplines as a whole by integrating them. 33 Preservice teachers, enrolled engineering class of Pedagogical Formation Education at a Faculty of Education of a state university in the Mediterranean Region of Turkey, performed the development process of integrated instructional material in the context of Instructional Technology and Material Design course. Data were collected through observation notes, open ended questionnaires, and clinical interviews. Content analysis was used in order to analyze data.

The Hadoop framework uses the MapReduce programming paradigm to process big data by distributing data across a cluster and aggregating. MapReduce is one of the methods used to process big data hosted on large clusters. In this method, jobs are processed by dividing into small pieces and distributing over nodes. Parameters such as distributing method over nodes, the number of jobs held in a parallel fashion, and the number of nodes in the cluster affect the execution time of jobs. The aim of this paper is to determine how the numbers of nodes, maps, and reduces affect the performance of the Hadoop framework in a cloud environment. For this purpose, tests were carried out on a Hadoop cluster with 10 nodes hosted in a cloud environment by running PiEstimator, Grep, Teragen, and Terasort benchmarking tools on it. These benchmarking tools available under the Hadoop framework are classified as CPU-intensive and CPU-light applications as a result of tests. In CPU-light applications, increasing the numbers of nodes, maps, and reduces does not improve the efficiency of these applications; they even cause an increase in time spent on jobs by using system resources unnecessarily. Therefore, in CPU-light applications, selecting the numbers of nodes, maps, and reduces as minimum is found as the optimization of time spent on a process. In CPU-intensive applications, according to the phase that small job pieces is processed, it is found that selecting the number of maps or reduces equal to total number of CPUs on a cluster is the optimization of time spent on a process.

— Ad-hoc networks are temporary networks, which use wireless media that consists of interconnected nodes
without a common network infrastructure using wireless media for immediate and dedicated network solutions. Ad-hoc
networks are much vulnerable against the threats compared to the traditional networks due to its nature of lacking of a
central control mechanism and the individual attitude of each node. In this study, the security threats and the routing
protocols defined for ad hoc networks are investigated and the findings are evaluated. The aim of the study is to reach a
generalized conclusion on the existing routing protocols in ad-hoc networks by evaluating the advantages and
disadvantages of these protocols. In this paper, it is shown that the routing and security protocols to be used in ad-hoc
networks should be designed by providing a resistance, robustness and high energy efficiency in order to overcome
security treats aiming for confidentiality, integrity and accessibility. The balance between resistance to threats, high
energy efficiency and robustness should be carefully considered and implemented in an autonomous way by weighting
each of them for a specific task.

Machine translation is a computational linguistics sub-field that studies translation methods and the
use of software to translate text between natural languages. Although machine translation is not as
accurate as human translation in terms of syntactic, semantic accuracy criteria, the usage of improved
methods has lead to obtaininig comparatively acceptable results. In recent years, self-learning
methods with statistical analysis of big data are being developed. The current development in machine
translation among Turkish languages has moved towards rule-based methods. However, one of
today’s leading methods, Statistical Machine Translation, is being poorly applied. For this purpose,
in this work N-GRAM based and Phrase based Statistical Machine Translation methods were applied
between Kyrgyz and Turkish languages, using limited training data. For both methods, the translation
quality was evaluated with BLEU scoring algorithm. According to test results, both applied methods,
provided translations with poor translation quality, 0.1 (one hundredths) on average. In most cases,
no translations obtained, or human translation incompatible results were observed. In order to reach
higher translation qualities, various suggestions were proposed.

65% of data in web compose of images. For this reason, elements of these images such as, quality, accessibility and size have great importance in digital world. Many studies related to image formats have been conducted in order to increase speed of transmission or installation as in limited mobile networks. Today’s most image formats used in web still use old compression formats. Thus, compression algorithms, which can provide high-level of image quality for lossy and losseless image without image distortion, has been
developed. This study focused on saving digital image data formats on web space and compression features of raster images. Particularly, JPEG and PNG digital image formats
compression algorithms and WebP algorithm which was developed by Google Inc. were compared in terms of SSIM quality index and size. Comparison was done by using encoded web images and results were presented.
As a result, when compared to the other digital image formats in web, WebP digital image format indicated better results in smaller file sizes and it provided close, similar and better
image quality.

Günümüzde verimliliğin artırılması, is akıslarının hızlandırılması, çalısanlar ve diğer kurumlarla daha hızlı iletisim kurulabilmesi, günlük yasantımızı kolaylastırması gibi birçok sebepten dolayı bilisim sistemleri hızla yaygınlasmaktadır. Bilisim teknolojilerindeki gelismeler sonucunda, merkezi yapılar yerlerini, dağıtık mimarilere, internet ve ağlar üzerinden erisilebilen elektronik uygulamalara bırakmıstır. Web uygulamaları, uzaktan erisimler, çevrimiçi sistemler, bilgisayar ağları, internet gibi elektronik bilgi altyapılarının kullanımının artması sonucunda ekavramlar (e-ticaret, e-öğrenme, e-rezervasyon, e-sınav, e-okul, e-banka, e-devlet vb.) günlük yasantımızın bir parçası haline gelmistir. Bilisim ortamlarının kullanımının artması ve yaygınlasmasına paralel olarak güvenlik tehditleri ve riskleri aynı oranda artmıstır. Teknik güvenlik önlemlerinin gelismesine rağmen bilisim sistemlerine karsı yapılan saldırıların sayısının artması ve bilgi sistemleri üzerinde yüksek derecede etki yapan hasarlar olusturması, teknik yöntemlerin bilgi güvenliğinin sağlanmasında yetersiz olduğunu göstermektedir. Bilgi güvenliğinin sağlanabilmesi için teknik önlemlerin yanında, idari önlemler (kurallar, cezalar, yaptırımlar vb), standartlar (ISO 27001,Ortak Kriterler vb) ve insan faktörü göz önüne alındığında bilgi güvenliği karmasık çözümler içeren ve yönetilmesi zorunlu hale gelen bir süreç halini almıstır. Bu çalısmada bilgi güvenliği yasayan bir süreç olarak ele alınmıs ve yönetilebilirlik gerekliliği ortaya konarak, bir bilgi güvenliği yönetim modeli gelistirilmistir.

Widespread use of internet reveals the idea that it can also be more widely used for educational purposes. In this respect, teachers have a very important function in education and the determination of teachers’ attitude towards internet using is also important. In the literature although it is possible to see many studies on pre-service teachers’ attitude towards internet use, studies identifying the attitude regarding in-service teachers’ internet using are not very common. In our study, which aims to determine the attitude of in-service teachers according to various variables, the Internet Usage Attitude Scale developed by Tavşancıl and Keser (2002) was used. The participant teachers’ attitudes towards internet using was analyzed and interpreted according to the variables of gender and duration of their weekly internet using. It was seen that a vast majority of the teachers have personal computers, connect to internet at home and have positive attitude concerning internet use. In addition to this it was concluded that female teachers have more positive attitude than male teachers regarding internet use in social interaction and communication.

Web technology is changing rapidly every day and the Internet has become a lifestyle for people all over the world. It is obvious that the life style of societies is in a process of change, as new habits are acquired. Even though Internet use is one of the new social habits, it is one of the most important factors that induce this change as regards the convenience it brings to communication and other areas. The widespread use of Internet implies the idea that it can also be more widely used for educational purpose. Since chemistry teachers have a very important function in education, the determination of teachers’ attitude towards Internet use is also important. In the literature it is possible to see many studies on teacher candidates’ attitude towards Internet use; however studies on appointed teachers’ attitude are not very common.

It is identified that one of the greatest threats against security in the next coming ten years will be cold cyber wars against information systems between countries. National information systems utilize the information technology infrastructure of enterprises in order to satisfy personal or enterprise needs. In the past years, attacks were taking place with no discrimination of targets, however in the recent years; attacks are organized, deliberate and pointed towards national information systems. Personal and enterprise level information security must be established in order to avoid information security threats that try to hamper or even destroy national information security, cause tangible and intangible damages on individuals and enterprises. In order to reduce the impact of such cyber threats to minimum at the national level, there are necessary critical enterprise and personal security precautions to be taken. The establishment of the enterprise and personal information security which form the stages of establishing national information security at highest level and development of a national security policy are among the first things that need to be done. In this paper, the strategic national information systems are identified, then personal and enterprise information security that are important stages in providing security for national information systems are described. The necessary security tests and the importance of education and awareness are discussed in the following section. Finally, evaluations have been performed on national information security and proposals have been put forward.

In this study, the awareness levels of elementary and high school students’ information and computer security were tried to reveal. A developed information and computer security scale was conducted to 2447 students from the center of Kahramanmaraş City, towns, small towns and villages of Kahramanmaraş. The data were assessed by using statistical analysis program.
About awareness of information and computer security both positive and negative findings were obtained. Basely, it was found that while students have sufficient awareness level in terms of ethical issues, they have low awareness level in terms of issues that required rules and knowledge. This situation reveals the idea that education and activities of awareness of information and computer security seem insufficient.

Tunus’ta 2010 Aralık ayında başlayıp, 2011’in başlarında yükselen, hızla Orta Doğu ve Kuzey Afrika ülkelerine
yayılan ve etkileri hala devam etmekte olan halk hareketlerine Arap Baharı adı verilmektedir. Otoriter yönetimlere
karşı özgürlük ve demokrasi talepleriyle ortaya çıkan harekette, bilgi ve iletişim teknolojilerinin etkin rol oynadığı
yaygın olarak kabul edilmektedir. Bu teknolojilerin kullanımının oynadığı rolün abartıldığını iddia eden görüşler de
vardır.
Bu çalışmada Arap Baharı’nda yaşanan sosyal aktivizmin, yerel sosyokültürel değişim ve küresel ağ toplumunun
etkileri olmak üzere iki temel dinamiğe sahip olduğu öne sürülmektedir. Bu iki dinamiğin izi sürülürken, konunun
bileşenleri, “sokak siyaseti” ve “ağ toplumu” kavramları eşliğinde ve birbiriyle ilişkisi üzerinden tartışılmaktadır. Bu
ilişki yeni aktivizmi yaratmıştır. Çalışmada yeni aktivizm, bölgedeki yeni sosyal aktörlerin, kültürel olarak devralmış

ortaya çıkan hareket biçimi olarak değerlendirilmektedir.
yayılan ve etkileri hala devam etmekte olan halk hareketlerine Arap Baharı adı verilmektedir. Otoriter yönetimlere
karşı özgürlük ve demokrasi talepleriyle ortaya çıkan harekette, bilgi ve iletişim teknolojilerinin etkin rol oynadığı
yaygın olarak kabul edilmektedir. Bu teknolojilerin kullanımının oynadığı rolün abartıldığını iddia eden görüşler de
vardır.
Bu çalışmada Arap Baharı’nda yaşanan sosyal aktivizmin, yerel sosyokültürel değişim ve küresel ağ toplumunun
etkileri olmak üzere iki temel dinamiğe sahip olduğu öne sürülmektedir. Bu iki dinamiğin izi sürülürken, konunun
bileşenleri, “sokak siyaseti” ve “ağ toplumu” kavramları eşliğinde ve birbiriyle ilişkisi üzerinden tartışılmaktadır. Bu
ilişki yeni aktivizmi yaratmıştır. Çalışmada yeni aktivizm, bölgedeki yeni sosyal aktörlerin, kültürel olarak devralmış
oldukları eski “sokak siyaseti” geleneğini yeni çağın yeni araçlarını kullanarak icra etmeleri/sürdürmeleri sonucunda
ortaya çıkan hareket biçimi olarak değerlendirilmektedir.

Gelişen teknoloji ve Internet kullanımının yaygınlaşmasıyla günlük hayatımızdaki hemen hemen tüm işler sanal ortama taşınmıştır. Bu gelişim çerçevesinde eğitim alanında da çeşitli uygulamalar yapılmaktadır. Eğitimde bilgisayardan çok farklı amaçlar için yararlanılabilir. Öğretim, üretim, iletişim amaçlı kullanmak bunlardan bazılarıdır.

Eğitimde verimliliği etkileyen en önemli etkenlerden birisi öğretmendir. Toplumun değerlerinin korunması, sürdürülmesi ve yeni değerlerin kazandırılmasında öğretmen en önemli öğedir. Eğitim fakültelerinde okuyan ve geleceğin öğretmenleri olacak olan öğrencilerin öğretmenlik mesleğini sevmeleri, mesleklerini başarıyla yürütebilmeleri için bir ön koşuldur (Tanel, Şengören ve Tanel). Bu çalışmada bilişim teknolojileri ve ilköğretim matematik öğretmeni adaylarının öğretmenlik mesleğine yönelik tutumlarının ne düzeyde olduğu araştırılmıştır. Tarama yönteminin kullanıldığı araştırmada veri toplama aracı olarak Tanel, Şengören ve Tanel (2007) tarafından geliştirilen “Öğretmenlik Mesleğine Bakış Açısı Tutum Ölçeği” kullanılmıştır. Araştırma ile öğrencilerin öğretmenlik mesleğine yönelik tutumlarına bakıldığında cinsiyet değişkenine göre kız öğrenciler lehine anlamlı bir ilişki tespit edilmiştir. Üniversite değişkenine göre Kahramanmaraş Sütçüimam Üniversitesi ile İnönü Üniversitesi öğrencileri arasında Kahramanmaraş Sütçüimam Üniversitesi öğrencileri lehine anlamlı bir ilişki olduğu görülmüştür. Anne öğrenim durumu değişkenine göre annesi ilkokul ve ortaokul mezunu olanlar arasında ilkokul lehine; ortaokul ve lise mezunu olanlar arasında lise lehine bir ilişki bulunmuştur. Öğrenim gördükleri bölümü isteyerek seçen öğrencilerle isteyerek seçmeyen öğrenciler arasında bölümü isteyerek seçenler lehine anlamlı bir ilişki bulunmuştur. Mezun olunca öğretmenlik yapmak isteyip istemeyen öğrenciler arasında mezun olunca öğretmenlik mesleği yapmak isteyen öğrenciler lehine bir ilişki bulunmuştur.
