Increasing Teacher Competence in Cybersecurity Using the EU Security Frameworks
Статья научная
A study was undertaken to identify the missing skill and expertise of teachers and other stakeholders in the field of EU cyber security regulatory documents and frameworks. In order to increase the knowledge in this area and promote the EU security frameworks the model for the continuous building of teacher competence has been proposed and planned to be implemented in Ukraine. The proposed model will contribute towards improving the excellence of educators and academics, as well as increase competitiveness of educational programmes on cybersecurity among similar institutions in the EU countries. Various studies focused on the development of competence of the students to prepare them for the job market and build a comprehensive portfolio, education-business partnerships and collaboration. However, the issue of developing teacher expertise to achieve high quality of education remains open. We highlighted the importance of creating a cybersecurity ecosystem through the cooperation with different stakeholders and by implementing the model for continuous development of teacher competence. Before building the model the overview and analysis of different teacher professional development approaches were conducted. Analysis showed that for our goal the best suitable approach is a model that consists of two stages based on self-education and group education approaches with 7 processes inside. The study revealed that competence may be achieved through a number of activities which may be grouped under four generic categories: student and staff training, academic and business seminars, business-oriented roundtable debates, and research. The model uses as main methods of achieving a better quality of education in cybersecurity the development of new training courses and modernization of educational programs, and for raising awareness among businesses and regulatory bodies - the workshops and roundtables.

The phenomenon of product/business failure, as well as lack of environmental sustainability and learning limitations, is fast becoming a recurrent ‘disease’ for investors, designers, design sponsors and education policy makers in many developing countries with poor persuasiveness contributing a large quota to such failures. This has greatly hampered the education, poverty alleviation and developmental efforts of the governments of such societies. In a bid to curb this negative trend, children, who are major influencers in product purchase behaviours of adults, have been targeted specifically by persuasive designers, in an effort to both educate and adopt them as means of reaching the larger populace. However, most researches in current persuasive system designs are limited to the information communication/management technology or computerized environments. These systems are technology/internet-driven and many potential users, in reality, in the developing world, unlike the rest of the world is often made to believe, do not have open access to such systems. Unfortunately, the effectiveness of any persuasive system is dependent on its accessibility to its user(s). Technological backwardness (often concealed behind ostentatious self-deceptive facades) has led to the poor persuasiveness of local persuasive systems and products in the third worlds. Therefore, adopting a mixed method for establishing the factor(s) limiting the efficiency of the computer/electronic-human interaction persuasive systems (CHIPS) in South-West Nigeria (N=900), this study established the need to adopt more of the product/entity-human interaction persuasive system (PEHIPS) as an effective alternative for third world countries as, based on the study outcomes, the CHIPS proved less relatively effective in comparison to PEHIPS in rural regions. It however recommends the alternating adoption of a combination of both computerized and entity/product driven systems for the purpose of optimizing persuasive effectiveness in developing worlds.

Information Hiding Using Least Significant Bit Steganography and Cryptography
Статья научная
Steganalysis is the art of detecting the message's existence and blockading the covert communication. Various steganography techniques have been proposed in literature. The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image is replaced with data bit. As this method is vulnerable to steganalysis so as to make it more secure we encrypt the raw data before embedding it in the image. Though the encryption process increases the time complexity, but at the same time provides higher security also. This paper uses two popular techniques Rivest, Shamir, Adleman (RSA) algorithm and Diffie Hellman algorithm to encrypt the data. The result shows that the use of encryption in Steganalysis does not affect the time complexity if Diffie Hellman algorithm is used in stead of RSA algorithm.

Data security is one of the biggest concerns in cloud computing environment. Although the advantages of storing data in cloud computing environment is extremely high, there arises a problem related to data missing. CyberLiveApp (CLA) supports secure application development between multiple users, even though cloud users distinguish their vision privileges during storing of data. But CyberLiveApp failed to integrate the system with certain cloud-based computing environments on multi-server. Environmental Decision Support Systems (EDSS) move away the technical load and focus mainly on decision-making activities. EDDS does not have a secure collaborative decision-making experience on cloud services. To integrate the security level for multi-server cloud infrastructure, Information Interpretation Code on Multi-Server (IICM-S) is proposed in this paper. To ensure the information with relevance to security on cloud-based computing environments, Information Interpretation Code (IIC) algorithm is initially developed. Thus, IIC guarantee that all information pertaining to cloud is in secured condition in order to prove the trustworthiness of data. In addition, the multi-sever cloud infrastructure in IIC provides access point for secure information recovery from cloud data server. The multi-server cloud infrastructure with IIC algorithm performs the recovery task on multi-server cloud infrastructure. The Multi-server Information (MI) scheme measures the integrity level with effective data recovery process. The integrity level on multi-server cloud infrastructure is ensured using two components, verifier and verify shifter. MI scheme proficiently check integrity using these two components so that not only the data integrity is provided as well as security is ensured in all cases using IICM-S. Experiment is conducted in the Cloudsim platform on the factors such as average integration time on multi-server, security level, recovery efficiency level.

Information Literacy and its Application in Nursing Education
Статья научная
Information literacy has been embedded by the university into the first year nursing curriculum. Embedding this literacy will not necessarily ensure the nursing graduates will apply this skill to the provision of high quality evidence-based health care. For this to happen information literacy skills gained in the classroom must contribute to sound decision making based on best practice evidence. This paper discusses the findings of a three phases research project designed to (i) determine the information literacy skills, confidence and problem solving abilities of students entering the university’s Bachelor of Nursing Program; (ii) determine if information literacy skills, confidence and problem solving abilities improve as a result of embedding information literacy instruction into a nursing course; and iii) ascertain whether there are any differences in information literacy skills, confidence and problem solving abilities based on the students demographic information. Data were collected in two sequential semesters using a questionnaire administered to the students. The response rates in semester one and two were 45 and 56 per cent respectively. Student confidence and awareness regarding information literacy is positively affected by learning experiences from semester one to semester two. Students indicated that they need both specific and regular instruction to adequately retain learning. Overall the study suggests that embedding information literacy instruction into the first year, first semester nursing program is beneficial. By the second semester the information literacy confidence and awareness of students increased as a result of intra-curricular instruction, however, problem solving skills need to be improved.

Integrating Apple iPads into University Computing Courses
Статья научная
The use of mobile devices is becoming increasingly common in both society and in the K-12 environment. Products such as the Apple iPad and the Microsoft Surface, among others, have matured to a point where university faculty are striving to integrate this increasingly ubiquitous technology into the classroom and the curriculum. This paper represents a case study examining one attempt to integrate the use of tablets into five university-level computing courses during the 2015-2016 academic year. The author used a set of iPads and accompanying classroom technology (e.g. Apple TV, keyboards) in an attempt to engage students and build their problem-solving and collaborative skills. Student feedback suggests that students were engaged, and the results for the iPad's impact on problem-solving and collaborative skills improved over the course of the year. A number of challenges were observed, including inadequate student knowledge of tablets, wireless connectivity issues, student resistance to the group learning afforded by the iPads, and keeping the tablets charged and clean. Future plans for the study intend to address the challenges uncovered, using student and instructor feedback as an impetus for future development. This paper serves as an experiential report designed to inform other faculty who may be looking into similar projects.

Integration Colour and Texture Features for Content-based Image Retrieval
Статья научная
Content-Based Image Retrieval offers an automatic way to extract visual image contents such as colour, texture, and shape so-called extracted features. Due to growing volume of digital images, Content-Based Image Retrieval is emerged to store and retrieved images from large scale databases. However, Content-Based Image Retrieval faces a challenge of meaning “Semantic gap” between machine and human conceptual. How to reduce this gap between colour and/or texture features that represent an object in the image? It is still the challenge that basically related to the effectiveness of image representation by extracted features and similarity measures between a query image features and database image features. Hence, different visual features have been proposed such as Gary Level Co-occurrence Matrix (GLCM), Local Binary Pattern (LBP), and Discrete Wavelet Transform (DWT) texture features that are extracted from gray-scale images. This paper presents an unsupervised algorithm that exploits data and score-level fusion to address the semantic gap. The algorithm first extracts mentioned features from colour images in HSV and YCbCr colour spaces to increase the effectiveness of image representation by integrating texture and colour visual information in terms of data-level fusion. Resulted similarity retrieval values are then fused in three versions of score-level fusion, summing values without weights, fixed, and adaptive weights using linear regression to raise relevant images in a ranked retrieved images list. WANG standard colour images are used to implement the algorithm. Rates of achievement in image retrievals are enhanced at both levels.

The implementation of the concept of building an information society implies a widespread introduction of IT in all areas of modern society, including in the field of science. Here, the further progressive development and deepening of scientific research and connections presuppose a special role of e-science. E-science is closely connected with the innovative potential of IT, including the Internet technologies, the Internet of things, cyber-physical systems, which provide the means and solutions to the problems associated with the collection of scientific data, their storage, processing, and transmission. The integration of cyber-physical systems is accompanied by the exponential growth of scientific data that require professional management, analysis for the acquisition of new knowledge and the qualitative development of science. In the framework of e-science, cloud technologies are now widely used, which represent a centralized infrastructure with its inherent characteristic that is associated with an increase in the number of connected devices and the generation of scientific data. This ultimately leads to a conflict of resources, an increase in processing delay, losses, and the adoption of ineffective decisions. The article is devoted to the analysis of the current state and problems of integration of cyber-physical systems in the environment of e-science and ways to effectively solve key problems. The environment of e-science is considered in the context of a smart city. It presents the possibilities of using the cloud, fog, dew computing, and blockchain technologies, as well as a technological solution for decentralized processing of scientific data.

Intelligent Controller for Synchronization New Three Dimensional Chaotic System
Статья научная
One of the most important phenomena of some systems is chaos which is caused by nonlinear dynamics. In this paper, the new 3 dimensional chaotic system is first investigated and then utilized an intelligent controller based on brain emotional learning (BELBIC), this new chaotic system is synchronized. The BELBIC consists of reward signal which accepts positive values. Improper selection of the parameters causes an improper behavior which may cause serious problems such as instability of the system. It is needed to optimize these parameters. Genetic Algorithm (GA), Cuckoo Optimization Algorithm (COA), Particle Swarm Optimization Algorithm (PSO) and Imperialist Competitive Algorithm (ICA) are used to compute the optimal parameters for the reward signal of BELBIC. These algorithms can select appropriate and optimal values for the parameters. These minimize the Cost Function, so the optimal values for the parameters will be founded. Selected cost function is defined to minimizing the least square errors. Cost function enforces the system errors to decay to zero rapidly. Numerical simulation will show that this method much better, faster and more effective than previous methods can be new 3D chaotic system mode to bring synchronized.

Nowadays with improvement in computer science, distributed systems have attracted remarkable attention and increasingly becoming an indispensable factor in our life. Massive-scale data processing, weather forecasting, industrial control systems, medical science, multi-tire architectures in enterprise applications, and aerospace to name but a few are the cases in point that distributed systems play a notable role. Inter-Process Communication or in a short form, IPC is specified as the heart of all distributed systems, therefore they are not formed without IPC. Numerous methods concerning IPC have been proposed so far that are utilized in diverse circumstances. According to the physical location of communication processes in applications, IPC could be established among either multiple processes on the same computer or several computers across a network. From the communication pattern’s perspective, these IPCs can be classified into two broad groups namely, shared memory and message passing. Although, it is not true to say when processes are performed on the same computer definitely employ shared memory to communicate if processes are executed on the different systems they inevitably communicate through message passing. By way of illustration, pipes use message passing patterns to make a connection between various processes but all of the processes are carried out on the same system. The aim of this research is to depict a categorization of the some IPC methods, give a brief description of them, and assess their performance in terms of transferring rate by sending multiple files in different sizes between client and server. As we expected, socket as the basic IPC, since it does not perform extra operations on the input data to be sent had a desirable performance compared to others. Although, to achieve some of the capabilities, like eliminating platform dependencies and asynchronous communication, it needs to add additional layers that make poor performance.

The increasing growth of internet and e-commerce had bartered the customer’s purchasing feature and service providers’ service policies. Moreover, there is no other criterion for quality of service (QoS) on the online network. Here the paper’s objective is to employ the importance of QoS to measure the utility quality of monetary enterprise on internet (e.g., Facebook (FB)). In this paper, the Weighted Sum method and Weighted Product method (WSM and WPM) are implemented using FB for their promotion and advertisement and then utilized the intuitionistic fuzzy value for the measuring of the QoS. The proposed methods are generally based on IF-aggregation operators and criterion weights. To calculate criterion weight, new intuitionistic fuzzy divergence is developed. Additionally, the IF-TOPSIS (technique for order preference by similarity to ideal) algorithm is also applied to check the validity of the result. This research examine not only the dimensions of QoS that users on FB liked and major brands are ‘preferred by’ by them, and which results as the most highly ranked features.

Investigating the redundancy effect in the learning of C++ computer programming using screencasting
Статья научная
The purpose of this study is to investigate whether does the redundancy principle occurs or not in the learning of C++ computer programming using screencasting. This principle was discovered by Mayer’s Cognitive Theory of Multimedia Learning (CTML) and stated that students learn better from graphics, and narrations than from graphics, narrations and on-screen text. There were mix outcomes pertaining to this principle, and the result might be due to the various topics learn by the students. Therefore, the subject introduction to C++ computer programming was chosen in this study to determine whether the redundancy principle occurs or not in the learning of C++ computer programming using screencasting. A true experimental pre-test and post-test research design was conducted, and sample were 65 first-year undergraduate students (aged 19-22). Samples were chosen based on the criteria that they have never attended any formal computer programming course prior to the study and were randomly assigned to two types of learning modes. The first group received the screencasting and narration (SN) mode whereas the second group received the screencasting, text, and narration (STN) mode. Results showed that the SN mode students outperformed the STN mode students in the post-test.

Investigation of Participation and Quality of Online Interaction
Статья научная
Advances in computer mediated communication technologies have sparked and continue to facilitate the proliferation of online courses, degree programs, and educational institutions. Leading the way with these advances has been the use of asynchronous discussion forums. However merely setting up a discussion forum does not always ensure quality participation and interaction. The way the course is managed has an impact on the participation as well. This paper compares the difference in course management over four study periods and discusses the resulting consequences on the participation and achievement of the students. This paper also investigates the quality of interaction as perceived by fully online students. The main benefits of this research are that it provides a guideline regarding what course management factors can make the difference in online participation in fully online courses, and how the quality of interaction can be designed.
