Rosalyn Gunobgunob-Mirasol
Reading is an indispensable tool in the academic world. Most, if not all, activities in varied collegiate courses entail the act of reading. There are many contributing factors that affect one’s ability to read and comprehend text materials effectively. Two of the many factors are the reader’s vocabulary size and their reading motivation. This study examined the relationship of the vocabulary size, reading strategies and the reading comprehension performance of college learners in a comprehensive university in the Philippines. A correlational analysis was employed to ascertain the relationship between the scores in the reading comprehension component of the course and the vocabulary levels tests by Nation [1]. The findings of this study hope to provide useful insights into the prediction of college learners’ reading performance and the teaching of vocabulary in the ESL context as well as the integration of learners’ reading motivation in the curriculum.

Organizational justice and cynicism: a mixed method study at schools

10.11591/ijere.v8i1.18296
Hüseyin Akar , O. Tayyar Çelik
This study aimed to investigate the relationship between organizational justice and cynicism at school organizations. Thus, explanatory sequential research design, in which both qualitative and quantitative methods are used, has been used. 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.

Current sensorless vector controlled induction motor drive

10.11591/ijra.v8i1.pp52-67
Vimlesh Verma
This paper presents a current sensorless vector controlled induction motor drive with only speed sensor present in the system. The same performance as that of normal vector control drives (which uses two current and one speed sensor) is achieved with the proposed current sensorless drive. Such an approach is suitable for applications, where speed sensor cannot be eliminated. Thus, elimination of current sensor results in reduction of cost, increases reliability, reduced size and noise immunity. A new current estimation algorithm is proposed in this paper. The current estimation algorithm, estimates the current in two phase stationary reference frame. The proposed current estimation technique can also be used as a fault tolerant algorithm for normal vector controlled drives in case of current sensor failures. The performance of the current sensorless drive using the proposed current estimation technique is verified through MATLAB/SIMULINK. Extensive simulation results are presented to confirm the effectiveness of the algorithm. The algorithm is also experimentally validated with the laboratory developed prototype and the results are presented. The prototype is built around a dSPACE 1104 controller board.

Development of alcohol triggered vehicle engine lock system

10.11591/ijra.v8i1.pp68-76
Ighalo Joshua , Uzairue Stanley , Ochonogor Charles , Amaize Peter , Kennedy Okokpujie
Drunk driving is a very dangerous behavior caused as a result of excessive consumption of alcohol therefore causing distortion in the thought pattern of its victims with a large percentage being drivers of vehicles of all forms. Most of the traffic accidents recorded in recent years are related to drunk driving. Solutions have been proposed, devices developed, all to the sole aim which is to reduce traffic accidents due to drunk driving but none has been quite cable of impairing the driver’s ability to drive. To this end, we model and design an alcohol triggered vehicle engine lock system. This project’s ability to impair the driver’s ability to drive makes it stand out from previous methods or devices developed to reduce road accidents due to drunk driving. The entire system is based on a microcontroller that is used to set an alcohol limit/ threshold which when reached or crossed upon sensing of alcohol in the air by the alcohol sensor, would trigger the buzzer alarm and warning LED of the circuit to alert the driver that his/her blood alcohol concentration at that moment in time wouldn’t be safe for driving. At this point the system automatically locks the ignition system of the vehicle within which it is embedded while an LCD displays information for the driver’s visuals incase the driver’s sight isn’t also impaired while in the drunk state. This project is a prototype to what is proposed with the vehicle’s engine system represented with a DC motor and its ignition system represented with a push button. The overall work was implemented with a constructed work, tested working and perfectly functional.

The mobile applications (apps) development has been gaining popularity for the past few years. Some mobile apps have been failing in its popularity because of the unattractive user interface and bad interaction with the apps. This was proven by previous researchers who have stated that the interaction between a user of mobile application and a graphical user interface could lead to some misunderstandings, errors and frustration from an inability to achieve a goal and could lead to failure of the mobile application. Most of the mobile application developers have been facing proper graphical user interface design recently. There is a noticeable lack of studies and research in the area of mobile application design compared to web application user interface (UI) design. Therefore, this research was done to evaluate the different gender on the mobile shopping application using eye-tracking technology. This research had proposed guidelines based on gender for mobile shopping application. These proposed guidelines can be preferred in the designing process of a mobile shopping application as it could provide a better user interaction and would prevent failure in its popularity by providing fast and user friendly interface.

The aim of this paper is to study and identify various threshold values for two prevalently used edge detection techniques, which are Sobel and Canny. The purpose is to determine which value gives an accurate result for identifying a leukemic cell. Moreover, evaluating suitability of edge detectors is also essential as feature extraction of cell depends greatly on image segmentation (edge detection). Firstly, an image of M7 subtype of Acute Myelocytic Leukemia (AML) is selected due to its diagnosing which were found lacking. Next, apply noise filters for the best of image quality. Thus by comparing image with no filter, median and average filters, useful information can be acquired. Each edge detectors is fixed with threshold value of 0-0.5 but for Cann edge detection the value can increase until 0.9. From the research, it is found that Canny edge with no filter and a threshold value of 0.7 gives a clearer image with less noise reduction.
