A NOVEL USER PROFILE-BASED FUZZY APPROACH FOR EVALUATING TRUST IN SEMANTIC WEB
Authors: ASHTARI SOMAYEH , DANESH MALIHE , Shirgahi Hossein
Published: June 2019

ABSTRACT: As a developed World Wide Web architecture, the Semantic Web collects traditional web contents with a formal and understandable semantic using a machine. The main purpose of the Semantic Web is to increase automation, web information processing, and improve interactions and collaboration among information systems. The subject of trust is one of the main challenges in the semantic web. Since different tools and individuals exist in the semantic web, a certain measure of trust in an entity cannot be used and a central system is responsible for data collection and estimating the reliability. In this study, a fuzzy system is used to evaluate the trust measure in the semantic web. For this purpose, the user profile data including a list of pages, user sessions, and visited pages in each session, and the time of page viewings are used as semantic parameters. After determining the general framework of trust in the semantic web, the effectiveness of the above mentioned semantic parameters on the trust measure is investigated and effective parameters are used for evaluation in the fuzzy system. The experiment results show that the proposed fuzzy method with a mean absolute error of 2.5% and an average precision of 97.5% could achieve the right value of trust in the semantic web. ABSTRAK:  Sebagai senibina World Wide Web, Semantik Web mengumpul kandungan web tradisional bersama semantik formal dan mudah difahami menggunakan mesin. Tujuan utama Semantik Web adalah bagi meningkatkan automasi, pemprosesan maklumat web, dan meningkatkan interaksi dan kerjasama antara sistem maklumat. Kepercayaan adalah salah satu cabaran utama dalam web semantik. Disebabkan perbezaan alatan dan pelbagai individu wujud dalam web semantik, langkah tertentu sebagai entiti dipercayai tidak dapat digunakan dan sistem pusat adalah bertanggungjawab bagi pengumpulan data dan kebolehpercayaan anggaran. Dalam kajian ini, sistem rawak telah digunakan bagi menilai tahap kepercayaan dalam web semantik. Bagi tujuan ini, data profil pengguna termasuk senarai halaman, sesi pengguna, dan halaman yang dikunjungi dalam setiap sesi, dan masa paparan halaman telah digunakan sebagai parameter semantik. Selepas menentukan rangka umum kepercayaan dalam web semantik, keberkesanan parameter semantik yang dinyatakan di atas pada ukuran kepercayaan telah disiasat dan parameter yang berkesan telah digunakan bagi penilaian sistem rawak. Keputusan eksperimen menunjukkan bahawa kaedah rawak yang dicadangkan dengan ralat mutlak purata sebanyak 2.5% dan ketepatan purata sebanyak 97.5% dapat mencapai nilai kepercayaan yang benar dalam web semantik.

Authors: Fadhil Hayder , Hussam Saif , Sadoon Yasseen
Published: June 2019

Our system proposes a wheelchair controlled by head gestures for people with quadriplegia paralysis (QP) or for those suffering from amputation of their hands and legs during the war in Iraq. The wheelchair design has an intelligent control that works with the movement of a patient‘s head in order to enable the patient to drive the wheelchair in the desired direction. The system consists of two main parts. The first is the transmitter in which sensing signals are transmitted to the second part and it consists of a 3-axes accelerometer (ADXL-345), a 433 MHz RF wireless receiver transmitter module, and Arduino UNO. The ADXL-345 sensor is placed in front of a hat that the patient wears. The system detects the direction of the patient's head movement then sends appropriate instructions to the wheelchair’s control part (receiving part). The receiving part is the wheelchair control system that consists of a 433 MHz RF wireless receiver transmitter module and an Arduino UNO. The Arduino processes the signals coming from the first part and moves the wheelchair accordingly in the desired direction. The research also provides an obstacle avoidance system with a range of 50 cm that prevents the wheelchair from colliding with objects. The head movement angles have been selected to be 40, 35 degree for vertical and horizontal movement respectively so that the QP patient feels comfortable to tilt his head in all directions and control the wheelchair easily. The system provides a very effective performance and accuracy.

ABSTRAK: Sistem ini bergantung kepada kerusi roda yang dikawal menggunakan isyarat kepala untuk mereka yang lumpuh kuadriplegia (QP) ataupun mereka yang dipotong tangan dan kaki semasa perang di Iraq. Ia merupakan reka bentuk pintar pada kerusi roda dan pesakit boleh mengawal pergerakan mereka dengan isyarat pada kepala. Sistem ini terdiri daripada dua bahagian utama iaitu yang pertama merupakan pemancar yang menghantar isyarat gerakan ke bahagian kedua dan ianya terdiri daripada 3 axis accelerometer (ADXL-345), modul penerima isyarat pemancar tanpa wayar 433 MHz RF dan Arduino UNO. Sensor ADXL-345 ini diletakkan di bahagian depan topi yang dipakai oleh pesakit. Sistem ini mengesan arah gerakan kepala pesakit dan kemudiannya arahan dihantar ke bahagian pengendali kerusi roda (bahagian penerimaan isyarat). Bahagian ini merupakan sistem pengendalian kerusi roda yang terdiri daripada modul pemancar penerimaan tanpa wayar 433 MHz RF dan Arduino UNO. Arduino memproses isyarat yang datang dari bahagian pertama bagi menggerakkan kerusi roda ke arah yang dikehendaki. Kajian ini turut menyediakan sistem mengelak halangan pada jarak 50 cm bagi menjauhi kerusi roda daripada melanggar objek. Sudut gerakan kepala telah dipilih pada 40, 35 darjah bagi gerakan menegak dan mendatar masing-masing, supaya pesakit QP merasa selesa bagi mengerakkan kepalanya ke semua arah dan mengawal kerusi roda dengan mudah. Sistem ini juga sangat cekap dan tepat dalam mengawal arah.

Authors: Saptari Asep Yusup , Hendriatiningsih S. , Bagaskara Dony , Apriani Levana
Published: June 2019

Building asset management is a system for organizing building assets in order to provide information to support decision making. One part of asset management is the inventory of building assets. Asset inventory can be done based on Building Information Modelling (BIM). BIM is one of the approaches to look at the building as a large unified database that can provide different information. The research case is theinventory of local government assets, especially state university assets because in Indonesia, state university assets belong to local government assets. The first step of local government asset inventory is to do three-dimensional modelling using a terrestrial laser scanner (TLS) assisted by Autodesk Revit. A textual database is created which contains the location code and item code on the asset referring to the Regulation of theMinister of the Home Affairs Number 108 Year 2016 on the Classification and Codification of Regional Property. The database is directly integrated with the threedimensional model of the building. By doing these two things, there will be a building asset management process that is integrated with BIM and can be used to plan assetdevelopment. ABSTRAK: Pengurusan aset bangunan adalah sistem untuk menganjurkan aset bangunan untuk memberikan maklumat untuk menyokong pengambilan keputusan. Satu bahagian pengurusan aset adalah inventori aset bangunan. Penyediaan aset boleh dilakukan berdasarkan Pemodelan Maklumat Bangunan (BIM). BIM adalah salah satu pendekatan untuk melihat bangunan sebagai pangkalan data bersatu yang besar yang dapat memberikan maklumat yang berbeza. Kes penyelidikan adalah untuk inventori aset kerajaan tempatan, terutamanya aset universiti negeri, kerana di Indonesia, aset universiti negeri adalah milik aset pemerintah daerah. Langkah pertama inventori aset kerajaan tempatan adalah melakukan pemodelan tiga dimensi menggunakan pengimbas laser bumi (TLS) yang dibantu oleh Autodesk Revit. Pangkalan data teks dicipta yangmengandungi kod lokasi dan kod item aset yang merujuk kepada Peraturan Menteri Dalam Negeri Nombor 108 Tahun 2016 tentang Klasifikasi dan Pengkodifikasi Harta Daerah.

Published: June 2019

ABSTRACT: The prediction of accurate traffic information such as speed, travel time, and congestion state is a very important task in many Intelligent Transportations Systems (ITS) applications. However, the dynamic changes in traffic conditions make this task harder. In fact, the type of road, such as the freeways and the highways in urban regions, can influence the driving speeds and the congestion state of the corresponding road. In this paper, we present a NNs-based model to predict the congestion state in roads. Our model handles new inputs and distinguishes the dynamic traffic patterns in two different types of roads: highways and freeways. The model has been tested using a big GPS database gathered from vehicles circulating in Tunisia. The NNs-based model has shown their capabilities of detecting the nonlinearity of dynamic changes and different patterns of roads compared to other nonparametric techniques from the literature.

ABSTRAK: Ramalan maklumat trafik yang tepat seperti kelajuan, masa perjalanan dan keadaan kesesakan adalah tugas yang sangat penting dalam banyak aplikasi Sistem Pengangkutan Pintar (ITS). Walau bagaimanapun, perubahan keadaan lalu lintas yang dinamik menjadikan tugas ini menjadi lebih sukar. Malah, jenis jalan raya, seperti jalan raya dan lebuh raya di kawasan bandar, boleh mempengaruhi kelajuan memandu dan keadaan kesesakan jalan yang sama. Dalam makalah ini, kami membentangkan model berasaskan NN untuk meramalkan keadaan kesesakan di jalan raya. Model kami mengendalikan input baru dan membezakan corak trafik dinamik dalam dua jenis jalan raya yang lebuh raya dan jalan raya. Model ini telah diuji menggunakan pangkalan data GPS yang besar yang dikumpulkan dari kenderaan yang beredar di Tunisia. Model berasaskan NNs telah menunjukkan keupayaan mereka untuk mengesan ketiadaan perubahan dinamik dan pola jalan yang berbeza berbanding dengan teknik nonparametrik yang lain dari kesusasteraan.

Jan Hornat: Transatlantic Democracy Assistance. Promoting Different Models of Democracy.
Authors: Bílková Veronika
Published: June 2019

The approaches of EU institutions and the US to democracy assistanceoften vary quite significantly as both actors choose different means andtactics. The nuances in the understandings of democracy on the part of theEU and the US lead to their promotion of models of democratic governancethat are often quite divergent and, in some respects, clashing.

This book examines the sources of this divergence and by focusing on therole of the actors’ "democratic identity" it aims to explain the observationthat both actors use divergent strategies and instruments to fosterdemocratic governance in third countries. Taking a constructivist view, itdemonstrates that the history, expectations and experiences withdemocracy of each actor significantly inform their respective definition ofdemocracy and thus the model of democracy they promote abroad.

This book will be of key interest to scholars, students and practitioners indemocracy promotion, democratization, political theory, EU and US foreignpolicy and assistance, and identity research.

Authors: Rajvanshi Dr. Rahul , Kothari Dr. Farzana , Dighe Dr. Milind , Patel Dr. Jhalak
Published: June 2019

Background: Voluntary donors normally tolerate blood donation very well, but, occasionally, adverse reactions of variable severity may occur during or at the end of the collection. The occurrence of adverse reactions to blood donation significantly hampers donor retention and negatively impacts on the universal availability of adequate numbers of blood donor units. 

Objective: To analyze the spectrum and prevalence of adverse reactions in blood donors in a tertiary care hospital-based blood bank in SSG Hospital, Vadodara. 

Materials and Methods: The details of blood donors who presented for donation from January 2107 to April 2019 period were retrieved from the departmental archives for analysis. These included type of donor, type and frequency of adverse reactions to blood donation.

Results: The prevalence of adverse reactions to blood donation was (315/35027) 0.9%; this occurred more frequently in first time donors compared to repeat blood donors. Presyncopal reactions were the most frequent adverse reaction encountered among the donors 52.38% (165/315).

Conclusion: Presyncopal reactions are common adverse reactions in our blood donor set; this has implications on transfusion safety and blood donor retention.

Keywords: Presyncopal reactions, adverse donor reactions, blood donor

Choice of Confounding in the 2k Factorial Design in 2b Blocks
Authors: C. Eze Francis
Published: June 2019

In 2k complete factorial experiment, the experiment must be carried out in a completely randomized design. When the numbers of factors increase, the number of treatment combinations increase and it is not possible to accommodate all these treatment combinations in one homogeneous block. In this case, confounding in more than one incomplete block becomes necessary. In this paper, we considered the choice of confounding when k > 2. Our findings show that the choice of confounding depends on the number of factors, the number of blocks and their sizes. When two more interactions are to be confounded, their product module 2 should be considered and thereafter, a linear combination equation should be used in allocating the treatment effects in the principal block. Other contents in other blocks are generated by multiplication module 2 of the effects not in the principal block. Partial confounding is recommended for the interactions that cannot be confounded.

The effect of diet on the fluctuations of human gut microbiota
Authors: Binh Nguyen Thi Thanh
Published: June 2019

It was previously thought that the establishment of the gut microbiota was completed within the first two years of life, and this community maintains fairly stable throughout the adult lifetime thereafter. However, recent evidence shows that the gut microbiota composition is constantly changing in the gut environment and is heavily influenced by diet. The individual differences responding to diets would root on the fluctuations of gut microbiota if dietary fluctuations affect the composition of gut microbiota so significantly.
Research and Indigenous Librarianship in Canada
Authors: Lee Deborah
Published: June 2019

This thought piece provides helpful information about ethical research practices related to research involving Indigenous peoples so that academic librarians (both Indigenous and non-Indigenous) are better informed about the complex issues that exist and arise in such endeavours. Woven throughout the paper are guidance and strategies to avoid causing harm when doing research with Indigenous peoples and communities, such as misrepresenting Indigenous peoples, cultures, and epistemologies. A brief account of the legacy of a long history of unethical research practices conducted by Western researchers who extracted Indigenous knowledge speaks to why Indigenous peoples do not trust academic research projects. Researchers need to question their own motives when they consider conducting research with Indigenous peoples and to respect that we want to be involved in our own solutions and in research that utilizes Indigenous values, with the goal that “nothing [is done] about us without us.” Key to building relationships and finding success in the research undertaken are an in-depth understanding of Indigenous protocols, values, and ways of knowing, as well as evidence of the researcher making a long-term commitment to the research and the community. Further, such an understanding provides an access point for librarians to contribute to the decolonization of library services while supporting Indigenous researchers.
Do Boards Determine Integrated Reporting in Nigerian Listed Oil and Gas Firms?
Authors: Orshi Teryima , Dandago Kabiru Isa , Isa Rehanet
Published: June 2019

Purpose: Integrated reporting is a process founded on integrated thinking, with the aim of issuing periodic integrated reports by firms about value creation over time. This study investigates the effect of board attributes (independence, diligence, and size) on the quality of integrated reporting of Nigerian listed oil and gas firms.
Design/Methodology: Panel data are obtained from annual reports of a purposive sample of 10 out of the 12 listed Oil and Gas firms in Nigeria from 2013 to 2017. These are analyzed using multiple regression techniques, via STATA 13.0 software.
Results: Based on the analysis conducted, findings show that the board independence and board size have a significant and positive effect, while board diligence has an insignificant and positive effect on the quality of integrated reporting, proxied by integrated reporting disclosure score (IRDSCORE). This outcome implies that having the optimum mix of members on the board influences the extent of integrated disclosures of listed oil and gas firms in Nigeria.
Practical Implications: Global corporate reporting is currently driving towards integrated thinking, incorporating financial, governance, social and environmental issues to promote long-term value creation. As a third world nation, the adoption of integrated reports is voluntary in Nigeria. However, considering the information needs of all stakeholders and appointing qualified persons on the board by shareholders, and formulating enabling policies in this direction by regulatory agencies would drive corporate reporting to be more integrative to drive long-term value maximization.

Authors: Fang Shyang-Chyuan
Published: June 2019

With the rapid rise of global temperatures and the negative effects of greenhouse gases, the destruction of natural resources and unlimited development is rapidly endangering the earth. The inefficient use of meat-based agriculture has contributed to contemporary concerns about environmental degradation and global food inequality. Therefore, the research attempted to establish a theoretical model to predict and explain the effects of health risks on vegetarian behavioral intention under climate change. The research investigated the vegetarian behavioral intention of university students derived from environmental perception, environmental attitude, and health risk perception. The research involved six universities in Taiwan, with a total of about 25,000 university students. A total of 1050 replies was received from the questionnaires, were carefully revised and all items were confirmed. Structural equation modeling (SEM) and Smart PLS data analysis were used to find the applicability of the survey data and the research model. The results showed that personality traits, health risk perception, and environmental value positively influence vegetarian behavioral intention. The model facilitated the evaluation of the variables related to environmental responsibility and behavior and could serve as a reference for policy decision-makers and teaching staff in terms of sustainable education.
Keywords: climate change, environmental attitude, environmental perception, healthy risk perception, vegetarian diet.

This research follows the previous study examining the effect of chemistry education on students’ perception and understanding to the nature of chemistry (NoC) as well as their attitudes towards it as a school subject. Grade 9 students (N = 282) at the end of their compulsory schooling were given a set of open-ended questions focused on their understanding to NoC, perception of chemistry topics’ importance, topics the students found interesting and their evaluation of chemistry as a school subject. The answers were analysed using the open coding approach. It is possible to conclude most of the students do not have a clear idea about the nature of chemistry. Students assess chemistry as a school subject in the middle of the 5 point Likert scale. The results of this research offer the background for a more complex analysis of effects influencing students’s conception of chemistry and its subject matter. Keywords: chemistry education, education effectiveness, interest in science, students’ attitudes.

Static electricity is the introductory chapter to electricity in all high school and university Physics textbooks. The interpretations of static electricity phenomena are not obvious, even in higher education. This research was conducted to identify the major difficulties which pre-service primary teachers encounter in explaining static electricity. They conducted electrostatic experiments focused on different types of electricity, in the context of an Introductory Physics Laboratory Course. The data were collected through the reports they wrote at the end of the course. The qualitative content analysis method was used in order to analyze the data. The sample, which was a convenient one, consisted of 200 pre-service primary teachers, 170 females and 30 males. The analysis showed that pre-service primary teachers have considerable difficulty conceptualizing the microscopic processes – more specifically, charging by induction – that explain these phenomena. The different roles electrons play in conductors and insulators seemed to pose difficulties for pre-service primary teachers. The findings implied an emphasis on microscopic models during macroscopic experimental processes. This could help pre-service primary teachers to understand the role of electrons in conductors and insulators and the different mechanisms involved in different types of charging.
Keywords: conceptual difficulties, content analysis, static electricity.

Geography learning is meaningless if it is not followed by the development of students' spatial thinking ability. Research aimed to 1) determine the effect of earthcomm learning and conventional learning on geography learning outcomes, 2) find out the effect of spatial thinking ability on geography learning outcomes, 3) find out the interaction between the application of earthcomm learning and spatial thinking ability on geography learning outcomes. Research used a quasi-experimental non-equivalent control group design. The research sample was taken from three high schools in Malang City, Indonesia. Geography learning outcomes data were obtained from paper-based test and spatial thinking ability data obtained from spatial thinking test instruments. Data were analyzed using Two Way ANOVA test using SPSS devices. The results of the research, 1) there is an effect of the application of learning to students’ geography learning outcomes, 2) there is an influence of the ability of spatial thinking on geography learning outcomes, 3) there is no interaction between the application of learning and spatial thinking on geography learning outcomes. Efforts to improve learning outcomes and spatial thinking ability are needed by students to face the challenges of global competition. Keywords: Earthcomm learning model, geography learning, geography learning outcome, quasi experimental, spatial thinking ability.

The aim of this research was to explore research trends and issues in Education for Sustainable Development (ESD) in South Korea. To accomplish this, we conducted an analysis of 222 peer-reviewed journal papers related to ESD in South Korea. The research concentrated on identifying four characteristics of ESD research: 1) key publication features, 2) the research topics described, 3) the research design employed, and 4) the types of sample/subjects. The results showed that the initial ESD research began in South Korea in 2005, and the number of the journal papers has increased since 2010. Regarding research topics, more research has been conducted on establishing conceptual or theoretical foundations related to ESD. Moreover, teachers’ attitudes or perceptions and program development associated with sustainable development were studied in depth. There were similar ratios of the theoretical research, quantitative research, and qualitative research regarding research design but mixed methods studies indicating the least ratio. Content analysis was the most prevalent analysis technique for quantitative/mixed ESD research. Regarding data sources or participants, the most common data source was the literature. Several research suggestions were made for assessing ESD programs and in-service teachers’ ESD professional development.
Keywords: ESD, South Korea, science education, technology education, research trends.

Studies of correlations between students’ beliefs and various aspects of student learning become one of the fastest growing research areas in the field of education and psychology. The aim of the current research was to analyze the correlations between learning environments, students' beliefs, and self-regulation in learning physics through structural equation modeling (SEM). There were 1010 students from the existing five public high schools in Jambi city, Indonesia, participating in the research. Three self-report questionnaires including (1) WIHIC, (2) CLASS, and (3) MSLQ were used to collect the research data. The data analysis showed that students’ beliefs were significantly and positively correlated with multiple dimension of self-regulation in learning physics (critical thinking and peer learning); while the dimension of sense-making and problem-solving ability significantly related to the affective component of self-regulation (test anxiety). However, the dimension of students’ beliefs did not have any significant effect on all of the self-regulation components. Additionally, learning environment dimensions were significantly related to students’ beliefs about physics on the dimension of conceptual connection and related to all of the self-regulation dimensions. Keywords: learning environment, self-regulation, students' beliefs, structural equation modeling.
