Title:	MIRRORED VEDIC VERTICALLY AND CROSSWISE MULTIPLICATION TECHNIQUE (MVVCMT): LONG INTEGER MULTIPLICATION ALGORITHM
Author:	EVON M. O. ABU-TAIEH, PHD
Abstract:	The paper presents Mirrored Vedic Vertically and Crosswise Multiplication Technique (MVVCMT) which is an algorithm based on Vedic Vertically and Crosswise Multiplication Technique. Vedic Vertically and Crosswise Multiplication Technique is an ancient Indian technique used to shorten the process of mental multiplication especially for big numbers. In India, the multiplication technique is still taught to kids to enhance their skills in mental multiplication. The proposed algorithm in this research was inspired by this ancient yet practical, easy to understand and apply multiplication technique. Vedic Vertically and Crosswise Multiplication Technique was rediscovered in 1965 by Swami Bharati Krishna Tirthaji in his book Vedic Mathematics. The proposed algorithm runs with only 100 multiplications rather than n2 based number of multiplications. In this paper, the first section explains the Vedic Vertically and Crosswise Multiplication Technique with and example and algorithm. Then the paper presents a hands-on example to show the simplicity of the original technique. Next, the paper presents the proposed algorithm name "Mirrored Vedic Vertically and Crosswise Multiplication Technique" which is dubbed (MVVCMT).

Title:	USERS ENGAGEMENT SUCCESS FACTORS IN INFORMATION SYSTEMS DEVELOPMENT
Author:	GHASSAN A. O. ABUSAMHADANA, NUR FAZIDAH ELIAS
Abstract:	Business organisations need to implement information systems (IS) mainly for keeping track of and managing its business activities, from planning to product delivery. In the last four decades, the information systems recorded low rates of success. Many IS projects, especially in the public sector, fail as a result of poor user engagement in the information systems development process. Engaging user in any information systems development process is claimed to contribute to the success of IS projects. Some studies have indicated that two factors which are user participation and user involvement can lead to successful user engagement in the information systems development. However, there is still no common understanding for measuring and validating the effect of these two factors. This paper discusses the importance of these two factors as the critical success factors for engaging users in the information systems development. The importance of these two factors was determined through the content review technique and mapping activity of eleven sub-factors identified from the literature. A-priori model for user engagement success will be presented at the end of this paper.

Title:	IMPROVED SELF-ORGANIZING MAPS BASED ON DISTANCE TRAVELLED BY NEURONS
Author:	HICHAM OMARA, MOHAMED LAZAAR, YOUNESS TABII
Abstract:	The Self-Organizing Map (SOM) is a commonly algorithm used for visualizing and classification of datasets, due to its ability to project high-dimensional data in a lower dimension. However, certain topological constraints of the SOM are fixed before the learning phase; the appropriate number of neurons has a major influence on the classification accuracy. Many researchers have tried to deal with this problem. This paper presents a novel approach to improve SOM based on distance travelled by each neuron. This approach is testing on two different databases of breast cancer. The model will classify the input vectors into two classes of cancer type (benign and malignant); the result obtained shows amelioration compared to classical SOM; up to 2% of improvement in classification accuracy is observed. We can conclude that our approach seems an efficient method in medical applications and especially for the cancer classification.

Title:	RESOURCE OPTIMIZED KERNEL SUPPORT VECTOR FOR SCALABLE AND RELIABLE MULTIPATH MULTICAST ROUTING IN MANET
Author:	M.SASEEKALA, DR.P.KAMALAKANNAN
Abstract:	Mobile ad hoc network (MANET) is a wireless ad hoc network where the mobile nodes are moved randomly. Due to the random movement of nodes, optimal resource utilization plays a vital role in multipath multicast routing. Each node itself acts as a router however it takes limited battery capacity, memory and processing power, varying channel conditions, less stability, bandwidth and scalability. Therefore, the lack of bandwidth and energy of the mobile nodes makes it more difficult to find the optimal route path. In order to attain optimal routing in MANET, Resource Optimized Kernel Support Vector (ROKSV) technique is introduced. The ROKSV technique improves multipath multicast routing by utilizing the optimal resources. Initially, the resources namely energy and bandwidth of the node is measured to attain scalable routing. After that, Optimized kernel support vector is applied to classify the node with optimal resource utilization for routing. Then the multipath is discovered between source and destination with the selected mobile nodes. The data packets are transmitted through the discovered route path. Finally, route path maintenance is carried out to achieve more reliability. The simulation is carried out to analyze the performance of proposed ROKSV technique with the parameters such as energy consumption, bandwidth, packet delivery ratio and delay.

Title:	FAST SPATIAL AND TEMPORAL CORRELATION-BASED REFERENCE PICTURE SELECTION
Author:	YONGTAE KIM, JAE-GON KIM, HAECHUL CHOI
Abstract:	Multiple reference pictures and variable prediction block sizes in motion estimation/compensation (ME/MC) adopted in video coding standards such as H.264/AVC and H.265/HEVC achieve high coding efficiency, but these tools require heavy encoding complexity. This paper introduces a reference picture selection method based on the spatial correlation between neighboring coded blocks and the temporal correlation between the reference pictures of a reference picture list. This method can reduce the number of reference picture to be searched in ME process. This reduction provides competitive performance with reduced computational complexity. Experimental results show that the proposed method reduces encoding run-time by 47%, with a negligible degradation of coding efficiency.

Title:	A NEW IMAGE CODE RECOGNIZABLE AT A DISTANCE
Author:	HYEON YEONG CHOI, WON-KEE HONG, JAEPIL KO
Abstract:	The IoT(Internet of Things) technology basically requires identifying things that emit their identities The RFID (Radio-Frequency Identification) and Beacon technology are widely used as well as Image Code such as Bar-code and the QR code. The QR code has strenth in terms of cost since it can be cheaply printed. However, the QR code can only be used to recognize very close things. In this paper, we propose a new sign board that having a recognizable image code at a distance. An additional design issue is to provide a room for human recognizable contents. Our solution is to place code blocks on the boundary region of a rectangle shaped sign board. To dispose the code blocks on the boundary, we propose a line-shaped code. Then, we have tailored the design of the code by considering recognition performance. As a result of these consideration, we finally designed easy-recognizable 4-bit code blocks, 16 blocks. By adding the corner block to the designed code blocks, we created an 8-byte prototype for the boundary code. We also privide the method to detect the boundary code in a given input image. In our experimental results, the proposed sign board achieves 100% identification performance for given input images where the size of the sign board is 1/12 of the size of the image and the shooting angle is 60 degrees or less.

Title:	E-COMMERCE STRATEGY USING BY SUNK COST AND MARKET ENTRY STRATEGY ON BRAND EXTENSION IN THE ERA OF COMSUMPTION POLARIZATION
Author:	JUNSIK KWAK
Abstract:	The size of E-commerce and M-commerce is increasing day by day in the era of consumption polarization. As online commerce evolves, consumers have the opportunity to conveniently compare, analyze and shop more products. As competition intensifies, the likelihood of success for new products is decreasing, and companies are forced to consider brand extension strategies that leverage existing brands' reputations. Companies are using a "line extension" strategy to name existing brand name for new products in the same category, or a "category extension" strategy to name existing brand name (hereinafter “parent brand”) for new products in other categories. In the case of new products launched in other product category, similarity with parent brand is very important. On the other hand, when making decisions, people are influenced by the time and effort invested in the past, not the future benefits and costs. Sunk cost effect is the great tendency to continue past decisions regardless of changes in circumstances due to the time, effort, and money invested in the past. In this study, we examined whether the consumer’s evaluation of the extended product in online depends on sunk cost, similarity, and market entry strategy when the category extension is performed. As a result, the three way interaction effect of sunk cost, similarity and market entry strategy was significant in the purchase intention. Specifically, in the case of low similarity, the probability of purchasing the extended brand was high only in the condition of the sunk cost and acquisition of the related company. On the other hand, when the similarity is high, the probability of purchasing the extended brand was high only in the condition of the sunk cost and internal R&D. In the case of low similarity for new product success probability, it is found that there is the highest purchase intention with sunk cost and acquisition of the related company. However, in case of high similarity, there is no significant difference in success probability with conditions. This result suggests practical implications that it is effective to use different communication strategy depending on similarity, sunk cost, market entry strategy when launching extended brand.

Title:	A STUDY ON ADVANCED RAM ALERT GENERATION ALGORITHM USING AIRCRAFT NAVIGATIONAL INFORMATION
Author:	Seoung-Hyeon Lee
Abstract:	The next-generation air traffic control system has advanced in a way that directs safely as many aircraft as possible in the limited airspace to meet rapidly increasing demands for air traffic. PBN is a navigation method recently released by ICAO to combine RNAV and RNP. As airspace capacity increased owing to the relaxation of the aircraft separation standards and the shortest routes between fixed points (or waypoints) that aircraft pass through were connected, the general flight distance and time have been reduced. PBN requires accuracy in the measurement of aircraft positions and flight route calculation for effective air traffic control. ADS-B sensor is a core component of PBN. ADS-B sensor data generated based on the GPS, the accurate information on the aircraft include a like position, altitude and direction, the generated data and transmits to the ground. In the existing air traffic control system, the position of the aircraft, which is measured by PSR has a lot of errors. Therefore, it has allowed a significant error rate in distance measurement and RAM centered on the aircraft to use the position of the aircraft. Fusion track data to be used in the next-generation air traffic control system utilizes the track data that combines PSR track and ADS-B sensor data, it can calculate the accurate position of the aircraft. In this paper, I proposed the accurate aircraft the distance measuring method and applying the measured result in the RAM using the fusion data track. First, for accurate position measurement and monitoring of aircraft on an allocated route, a virtual aircraft position on a route is mapped in reference to rectangular coordinates with straight lines and aircraft position. Second, the distance between two points is calculated by means of a Vincenty formula algorithm, and the calculation result is utilized for aircraft conformance monitoring. When the method proposed in this paper is applied, it is possible to reduce the separation gap of an aircraft for more accurate aircraft position measurement, and a safe navigation of aircraft as much as possible in the limited airspace is guaranteed. Also proposed a method for secure transmitting aircraft safety information to a controller or an external system using a physical unidirectional transmission method.

Title:	EMOTIONAL LIGHTING SYSTEM ABLE TO EMOTION REASONING USING FUZZY INFERENCE
Author:	BO-RAM KIM, DONG KEUN KIM
Abstract:	Recently, the development of emotional lighting technology has been attracting attention for its potential uses in various fields. This reflects the increasing awareness of and interest in the psychological and emotional states of people, and aligns with the increase in demanding for emotional-friendly products. In previous works focusing on emotional lighting, emotions were inferred by measuring the biometric signals of subjects using separate devices or genetic algorithms. However, these methods are unsuitable for mobile devices because of the complexity of both the measurement process and the inference of emotion. To solve this problem, a smart emotional lighting control system which infers emotions through fuzzy reasoning using heart rate and RR interval is proposed below. Experimental results yielded an average 90.67% accuracy in performance estimation for this fuzzy reasoning system. These results indicate that the proposed method has the potential to provide appropriate lighting through reasoning drawing directly from users’ emotions, and is expected to be of future use in various fields.

Title:	DEVELOPING PROBLEM-SOLVING AND CRITICAL THINKING ABILITY WITH THE USE OF CROWDSOURCING IN UNIVERSITY WRITING INSTRUCTION
Author:	HWA-SEON KIM, KYEONG-OUK JEONG
Abstract:	In the recent trends, writing education has been transformed from teacher-centered to learner-centered education, and has shifted from theory-oriented writing education to writing education as the problem-solving strategy. Under the paradigm shift in writing education, it has become essential to integrate new technology that can help students actively engage in the writing process or help them realize writing as collaborative learning experience. Among diverse innovative instructional procedures, crowdsourcing can be integrated into writing education, which strives to develop students’ ability for problem-solving and critical thinking through the use of collaborative learning and collective intelligence. This paper tries to incorporate new technological strategies into writing education at two levels. The first level is to design classroom writing activities for online collaborative learning through the use of the online authoring tool. The second level is to develop classroom activities for the students to engage in producing their own writing textbook materials with the utilization of crowdsourcing as collective intelligence into the writing course. In this study, a prototypical instructional model is proposed for the classroom implementation of crowdsourcing into writing education. This study also scrutinizes the responses and attitudes of the participants about their learning experiences of engaging in the writing tasks via crowdsourcing as collective intelligence and Google document as an interactive course platform.

Title:	IOT MULTITASKING: DEVELOPMENT OF HYBRID EXECUTION SERVICE ORIENTED ARCHITECTURE (HESOA) TO REDUCE RESPONSE TIME FOR IOT APPLICATION
Author:	POONAM GUPTA, K V V SATYANARAYAN, D D SHAH
Abstract:	IoT solutions are formulated and accomplished to cope with distinct challenges influenced by domain-specific necessities, thus not considering issues of visibility, scalability, interoperability along with use-case independence. Consequently, they can be less principled, the vendor focused and barely replicable as any generalized design available. The conventional SOA model address the architecture design issue, as core issue with conventional SOA is, it does not look into whether existing application platforms can provide the solutions to help with the implementation of IoT as a generalized approach for numerous tasks. To upgrade the framework of existing IoT options, present research developed new hybrid execution service oriented architecture model as a “middleware” which identifies new principles for developing IoT architectures and supporting the interoperation of IoT solutions. In this particular work, we seek to fill this gap and additionally we suggest an architectural strategy in line with SOA that targets the reasoning behind to come up with the development of new Internet of Things ibroker, and every sensing gadget is believed being a service using a single interface as an option to traditional single-use case designs. By this new framework, we accomplished modularization, powerful resource reuse, a boost in efficiency, loosely recourse coupling. In summary, this paper focuses on multi-tasking of systematic execution of request and response with development of architecture called “Hybrid Execution Service Oriented Architecture” (HESOA).

Title:	CONVERTING OF AN XML SCHEMA TO AN OWL ONTOLOGY USING A CANONICAL DATA MODEL
Author:	ADIL JOUNAIDI, MOHAMED BAHAJ
Abstract:	The eXtensible Markup Language (XML) has known since its beginnings an undeniable success. Defined since its origins as a meta-language facilitating the development of specialized tags Languages, nowadays, many documents benefit from the XML frame. But even if this language is strongly used in the web as a way of data exchange between applications, it still lacks the capacity of defining the web resources and the system that uses them, and also the capacity of expressing the knowledge provided by XML documents. It’s these lacks that proposes the Web Ontology Language (OWL) proposes to fill. In fact, OWL is a language for ontologies representation in the context of Semantic Web (SW). It’s in this context that we’re obliged to come up with a solution that allows migration to the SW in order to follow the WEB evolution. Among the suggested solutions, our approach is based on the Canonical Data Model (CDM) through the implementation of a set of rules allowing the transformation of an XML schema’s definition (XSD) to an OWL ontology. This mapping will transform not only the nodes of an XML file, but also the relationships between these nodes in order to maintain the same structure.
