The quality of education is primarily determined by the academician expertise, skills, abilities and competences. Poor quality of education will give bad impact to the institution.  It is very important to enhance the quality of service to ensure education system in Malaysia higher education is at par as international education standard. To achieve the international standard, the teaching quality of lecturers must be seriously taken into consideration. An appropriate method of lecturers’ evaluation should be used to measure lecturers’ performance and credibility. The purpose of this study is to improve the lecturers’ evaluation score by using Analytic Hierarchy Process (AHP). AHP is used to obtain the weightage of each criteria in lecturers’ evaluation.  The results show that teaching delivery carries the highest weightage, followed by assesment, course content and course material, lecturer’s interaction and lecturer’s commitment criteria. By implementing a new method of calculation, the overall score will be more accurate in describing the overall lecturers performance from students’ point of view.

Authors: Ahmad Nor Azizah , Mohd. Drus Sulfeeza , Abu Bakar Nur Azaliah
Published: April 2019

This article on Systematic Literature Review (SLR) provides the issues and challenges faced by organizations when adopting EA.  Firstly, a review of literature that discusses the problems and challenges was undertaken.  Methods and theories adopted were reviewed to identify the existing approach and perspective on resulting factors that influenced EA adoption.  Based on the inclusion and exclusion criteria defined in the review process, 16 articles were selected.  A total of 19 challenges and problems were identified such as EA misconceptions, overlapping organizational rules, unclear leadership as well as lack of business and IT alignment.  A sum of 15 factors from multidimensional contexts that influenced the EA adoption in the organization were also discussed, such as top management support, governance, communication as well as EA knowledge and skill.  This SLR also reflected that there were relatively little empirical studies conducted on EA adoption studies. The existing studies tend to apply single and multiple theories from the organization and management domains in one study.  By understanding such issues and challenges, risks can be reduced and avoided when introducing EA to organizations, and subsequently ease the deployment process. Thus, this article may shed light on understanding  the organizational-related factors and the underlying relationships of EA adoption. As a result, an effective adoption of EA can be facilitated in the organizations.
Light weight authentication protocol for WSN using ECC and hexagonal numbers
Authors: Toy Noel , T Senthilnathan
Published: April 2019

Wireless Sensor Network (WSN) is a spatially distributed network. It contains many numbers of distributed, self-directed, small, battery powered devices called sensor nodes or motes. In recent years the deployment of WSN in various application domains are growing in a rapid pace as with the upcoming boom of Internet of Things (IoT) and Internet of Everything (IoE). However, the effectiveness of the WSN deployment is restricted due to the constrained computation and power source. Hence, many researchers have been proposing new approaches and models to improve the efficiency of the domain specific WSN deployment procedures. Though, many research communities addressing various issues in WSN deployment, still the privacy and security of such networks are susceptible to various network attacks. Thus, it is necessary to practice different models for authentication and privacy preservation in a highly dynamic resource constrained WSN environment to realize the effectiveness and efficiency of the deployment. Hence, this paper addressing an authentication scheme that can reduce energy consumption without compromising on security and privacy. In order to provide a light weight authentication mechanism, this paper proposing an authentication mechanism for WSN deployment by combining the features of Elliptic Curve Cryptography (ECC) and Hexagonal numbers. The feature of ECC is used to reduce the key size and the effectiveness of generating hexagonal numbers is used for minimizing the energy consumption in a resource constrained WSN environment. The results of the proposed approach are evaluated with the different authentication models and the results were indicating that the proposed approach can perform better than the other approaches.

Authors: Abdullah Afrah Thamer , Ali Amer Mejbel
Published: April 2019

This paper adopted a thermal network method (TNM) based on  Motor-CAD software, and Matlab/SIMULINK, with finite element method (FEM) based on Flux2D software to perform a thermal analysis of a totally enclosed fan-cooled (TEFC), squirrel cage, three-phase induction motor. The thermal analysis is achieved based on a precise knowledge of the test motor geometry, materials, and heat sources (losses). The estimation of heat distribution inside the test motor by this three software is done successfully with a good agreement between its results. The proposed triple-software methodology for this work can be adopted from the motor designer instead of using an experimental test based on a real motor.

Authors: Nurul Khotimah Wijayanti , Suciati Nanik , Anggita Tiara
Published: April 2019

Sign Language Recognition System (SLRS) is a system to recognise sign language and then translate them into text. This system can be developed by using a sensor-based technique. Some studies have implemented various feature extraction and classification methods to recognise sign language in the different country. However, their systems were user dependent (the accuracy was high when the trained and the tested user were the same people, but it was getting worse when the tested user was different to the trained user). Therefore in this study, we proposed a feature extraction method which is invariant to a user. We used the distance between two users’ skeleton instead of using the users’ skeleton positions because the skeleton distance is independent to the user posture. Finally, forty-five features were extracted in this proposed method. Further, we classified the features by using a classification method that is suitable with sign language gestures characteristic (time-dependent sequence data). The classification method is Dynamic Time Wrapping. For the experiment, we used twenty Indonesian sign languages from different semantic groups (greetings, questions, pronouns, places, family and others) and different gesture characteristic (static gesture and dynamic gesture). Then the system was tested by a different user with the user who did the training. The result was promising, this proposed method produced high accuracy, reach 91% which shows that this proposed method is user independent.

Authors: Bala Mishra Deepti , Abhinna Acharya Arup , Mishra Rajashree
Published: April 2019

Software testing is very time consuming, labor-intensive and complex process. It is found that 50% of the resources of the software development are consumed for testing. Testing can be done in two different ways such as manual testing and automatic testing. Automatic testing can overcomes the limitations of manual testing by decreasing the cost and time of testing process. Path testing is the strongest coverage criteria among all white box testing techniques as it can detect about 65% of defects present in a SUT. With the help of path testing, the test cases are created and executed for all possible paths which results in 100% statement coverage and 100% branch coverage .This paper presents a systematic review of test data generation and optimization for path testing using Evolutionary Algorithms (EAs). Different EAs like GA, PSO, ACO, and ABCO based methods has been already proposed for automatic test case generation and optimization to achieve maximum path coverage.
Effects of Test Level Discrimination and Difficulty on Answer-Copying Indices
Authors: Sunbul Onder , Yormaz Seha
Published: April 2019

In this study Type I Error and the power rates of ω and GBT (generalized binomial test) indices were investigated for several nominal alpha levels and for 40 and 80-item test lengths with 10,000-examinee sample size under several test level restrictions. As a result, Type I error rates of both indices were found to be below the acceptable nominal alpha levels.  The power study showed that average test difficulty was very effective for power (true detection) rates of indices. Clear patterns were observed for the increase of test difficulty in favor of both ω and GBT power rate. Contrary to expectations; average test discrimination was not as effective as average test difficulty. The results of the interaction effects of item discrimination and difficulty showed that for the cases whose b parameters were lower than 0 with weak discrimination, indices had weak power for both ω and GBT. In addition, for the cases whose b parameter levels were below zero with high discrimination indices, the power performance of both answer-copying indices were very weak. Results for test length showed that with the increase of test length the power rate of both ω and GBT tended to increase. Also, ω performed slightly better than GBT or very close to GBT for 80-item test length however, ω performed better than GBT in terms of power rate for the cases with 40-item test length

Authors: Izgar Gokhan , Akturk Ahmet Oguz
Published: April 2019

The purpose of this study is to investigate the relationship between peer assessment and instructor assessment and make a comparison with views of preservice teachers. Since qualitative and quantitative methods were used together in the study, it was grounded on the mixed method approach. The quantitative data in this study, in which 27 preservice teachers participated on a voluntary basis, were obtained from scoring rubric whereas qualitative data were obtained from a semi-structured interview form prepared by the researchers. Statistical analyses were conducted to analyze the quantitative data collected within the scope of the study, whereas Pearson Product-Moment Correlation Coefficient was used to analyze the relationship between instructor assessment and peer assessment, and paired samples t test was used to determine the differences between pairwise groups. The qualitative data, on the other hand, were analyzed using the content analysis technique. As a result of the analysis, it was seen that there was a positive and significant correlation between instructor assessment and peer assessment. When the preservice teachers’ views were examined, those views rose to prominence stating that making assessments contributed to learning; they grew aware of imperfect knowledge; questioning and critical thinking improved, and fair assessment skills developed. This was interpreted to mean that preservice teachers could distinguish between adequate and inadequate work. However, when the preservice teachers’ views concerning their assessments by their peers were examined, the view attracted attention stating that friendship relations and personal problems affected assessment negatively and therefore peers gave low scores. At this point, when the mean scores were examined, it was seen that mean peer scores were higher than instructor mean scores. This was interpreted to mean that some preservice teachers did not have confidence in their peers.

Authors: Guce Ivee Kalalo
Published: April 2019

The study investigated the influence of journal writing on the senior high school students’ attitude toward mathematics. A mixed-method approach, particularly the convergent parallel design, was used in this study. Using Scale on Attitude Toward Mathematics (SATM) (Guce & Talens, 2013), the students’ attitude toward the subject was measured in four subscales—liking or disliking mathematics, tendency to engage in or avoid mathematical activities, belief that one is good or bad in mathematics and belief that mathematics is useful or useless. Using focus group discussion, the insights of the students on journal writing as a mathematics class activity were gathered. Results using quantitative data revealed positive significant differences in the attitude of the respondents in terms of (i) liking mathematics and (ii) having the tendency to engage in mathematical activities. This aligned with the result in the focus group discussion which suggested that students perceive journal writing as a helpful tool for them to enjoy mathematics and engage in it. The activity, thus, may be regarded as a means to improve students’ attitude toward mathematics.

Published: April 2019

Democracy, a lifestyle as much as it is a form of government, begins to be learned in the family. The youth observe and acquire the democratic attitudes of their parents. The task of passing it on to the new generations and helping them acquire democratic values is the mission of schools, namely teachers. It is a commonly known fact that developmental level of countries shows parallelism with the democratic attitudes of individuals. It is important to understand the democratic perceptions and attitudes of teachers who are responsible for positioning democratic structure and thus raising the democratic level of countries. For this reason, the research aims to examine the democratic perceptions and attitudes of music teacher candidates in terms of some variables. Data collected using the democratic attitude scale were analyzed using t-test, Kruskal-Wallis H test, and Spearman’s correlation coefficient. Results showed that attitude scores did not change according to gender, level of parents’ education or the year students were in. Scale scores were negatively correlated with the amount of parents’ income. There was no correlation between the students’ GPAs and the scale scores. Music teaching requires a democratic environment intrinsically; therefore, the democratic perceptions and attitudes of the music teacher candidates who will carry out the music lessons in which they should maintain the democratic environment must be determined. As aforementioned notions suggest, this study is of the essence since the results will shed light on the academic staff in the institutions that train music teachers.

Under the quantitative part, meta-analysis has been used so that 159 studies consist of articles and dissertations about cynicism being done within Turkey have been reached throughout literature. With further enquiries, it was found that 16 of them include the relationship between organizational justice and cynicism. Considering inclusion criteria, eight studies which include necessary data for the relationship between organizational justice and cynicism were put into meta-analysis step. However, in the qualitative part, the research was designed through phenomenological research design in which 17 teachers, chosen in terms of maximum-variation sampling strategy, were interviewed via a semi-structured interviewing form. The results revealed that teachers' perceptions for organization justice have a strong but negative effect on their likelihood to experience cynicism while it was also found that publication type is not a proper moderator on effect size. On the other hand, within the qualitative analysis, it was found that teachers develop negative beliefs against school, managers and teachers; experience feelings such as anger, distrust, sadness, hatred and alienation and thus criticize school and managers, behave recklessly and opponent as a result of unfair practices.

Nowadays, Innovation is known as an essential component of competitiveness, classified in different types in literature. For instance, on one hand it is classified based on OECD as product, process, marketing and organizational innovations and on the other hand as incremental, competence developing, market developing and radical ones based on the degree of internal and external newness. Also, innovation models have changed from “simple linear” to “networking interactions” and concepts such as ‘open innovation’ and ‘innovation network’ have become important to both academic and market society due to intensive global competition. Therefore, this paper tried to empirically study and analyze the types of innovation based on OECD regarding to other classification based on the degree of internal and external newness in a networking interaction. Thus, in order to empirically explore the relations between these two classifications, we used the data of last three years (2008-2011) of 50 companies from the network Pardis Technology Park (PTP) in Iran as a case study. The results showed that most of the innovations as product, marketing and organizational were new to the market. Also marketing and process innovations were more related to radical and incremental innovation respectively and less organizational innovations were incremental.

Indonesia is geographically located in the disaster vulnerable area and frequently hit by various disasters such as earthquake, flood, etc. So that Indonesian people aware that the disaster information system is very important. Thus, the development of information and communication technology application is needed for disaster management. For this purpose, this paper proposes on the development of online disaster information system based on location based service (LBS) technology by using short message service (SMS) gateway and global positioning system (GPS). Then,the web-based prototype of online disaster information system is designed and developed as the media to provide information of location and situation of the disaster area. Furthermore, a user interface is also designed and developed to transmit input data as the location information using manual SMS and automatically using smartphone based on SMS/GPS. The research method used in this research is a spiral method that begins with conceptual design, prototype development, application test, and evaluation. The results of this research are the web-based information system and the implemented user interface application (we called ASIKonLBS) for Android based smartphone. The online mapping of input data from smartphone to the web-based system has been tested. It shows that the disaster location information can be mapped to Google Maps timely and accurately that can be accessed using the Internet connection. The evaluation to mapping delay time shows that it is lower than the refresh time of the web-based system. Therefore, the proposed online system can be categorized as a real-time system.
Proxy-Protected Proxy Multi-Signature Based on Elliptic Curve

Published: April 2019

In this work, we propose a proxy-protected proxy multi-signature scheme based on EllipticCurve Digital Signature Algorithm (ECDSA), which aims at providing data authenticity,integrity, and non-repudiation to satisfy the basic properties of partial delegation proxy signaturedescribed by Mambo et al. as well as strong proxy signature properties defined byLee et. al. The proposed signing/verifying scheme combines the advantages of proxyprotectedsignature and multi-signature scheme. The security of the proposed schemes isbased on the difficulty of breaking the elliptic curve discrete logarithm problem (ECDLP).The scheme proposed is faster and secure than the multi-signature based on factoring ordiscrete logarithm problem (DLP). The final multi-signature of a message can be verifiedindividually for each signer or collectively for a subgroup or entire group as well. Finally,the proposed proxy-protected proxy multi-signature schemes can be used in E-commerceand E-government application, which can be implemented using low power and small processingdevices.

Published: April 2019

The article reports on our work in conducting performance measurement for the management of Information Technology (IT) by applying the Balanced Scorecard (BSC) at Mulawarman University, Samarinda, East Kalimantan, Indonesia. The results of this study are then used to propose a hybrid framework that applies both BSC and a artificial intelligence (AI) techniques in order to measure the performance of IT governance generally. This article also examines BSC’s abilities and its flexibility compared to other methods in measuring the performance of IT governance. The proposed hybrid framework is expected to yield a management that produces a scorecard measures that are more rigorous, accurate and consistent with the objectives and organizational strategies in non-profit organizations, especially educational ones.
