Title:	FORECASTING AUDIENCE OF MOTION PICTURES CONSIDERING COMPETITIVE ENVIRONMENT
Author:	SEONYEONG PARK, TAEGU KIM
Abstract:	Film industry is one of the most prospective cultural business sectors and attracts much of public attention. However, investment on individual film titles is notorious for its high risk level, which has raised the necessity of research on the influential factors for box office revenue. Despite of abundant extant studies, those attempts have been mostly limited to a certain kind of factors and the competitive environment is even hardly explored. In this regard, we investigate the significance and relative contribution of a wide variety of possible influential factors including distribution power and competition. In this study, we devised various new variables to reflect competition environment and categorized independent variables into several groups in order to compare their influences. Results showed that all various information reflected in four variable groups contribute to box office revenue in both estimation and forecasting. Between mathematical models, SVM models exhibit better result than linear models as expected. Regarding competition variables, the number of competitors is found to be more effective compared to their distribution power.

Title:	LEVENSHTEIN DISTANCE-BASED REGULARITY MEASUREMENT OF CIRCADIAN RHYTHM PATTERNS
Author:	TAEK LEE, HOH PETER IN
Abstract:	In this paper, we introduce an algorithm and an application for modeling user’s circadian rhythm with activity trackers, also known as smart bands (e.g., Misfit Shine or Fitbit). The proposed algorithm detects anomalies in the users circadian rhythm pattern (i.e., activity pattern of 24-hour cycle). Diurnal biorhythm data were collected using smart bands and the data were analyzed using Levenshtein distance. We evaluate the performance of the proposed algorithm to distinguish between ordinary days and abnormal days. During the experiment period, the users recorded the mood, fatigue, and event occurrence of the day, and evaluated the performance of the proposed algorithm through comparison with users recorded opinions. In the user study, the proposed method detected normal or abnormal patterns of life rhythm with 86% accuracy.

Author:	SEONG-WON KIM, YOUNGJUN LEE
Abstract:	As the importance of computing education has increased, Korea has strengthened its informatics courses in the 2015 revised national curriculum. However, there is no previous research on the newly added area of physical computing. In this study, Arduino was selected as a physical computing device to be used in school settings and developed educational program. In addition, the developed educational program was applied to high school students for 36 hours of instruction time. As a result of the application, there was no statistically significant change in the creative problem-solving ability of high school students who received the Arduino-based education. Upon investigating their opinions on Arduino-based education, the students who participated in the class said the Arduino-based education program was interesting and provided an accomplishment. However, they felt that the class was difficult because of factors such as design and debugging. Based on these results, it was confirmed that consideration of teaching-learning methods, teaching materials, and activities is necessary for high school students to teach physical computing.

Author:	SYAIFULNIZAM ABD MANAF, NORWATI MUSTAPHA, MD NASIR SULAIMAN, NOR AZURA HUSIN, M. N. SHAH ZAINUDDIN, HELMI ZULHAIDI MOHD SHAFRI
Abstract:	Coastal zones are constantly exposed to changes caused by natural processes, anthropogenic activities or both, which can precariously alter the coastal landscapes of many countries. Thus, monitoring of coastal zones is needed to provide important information about current conditions of a countrys coastal areas by examining changes that are taking place. In this respect, such monitoring can be carried out by traditional ground survey, airborne aerial photo, or remote sensing. However, the former is more effective and efficient as it can extract vital boundary information from satellite images using appropriate image analysis. Nonetheless, shoreline extraction has a number of challenges, and many methods have been proposed to improve such extraction, such as the use of machine learning methods. Thus, this study was carried out to determine the most effective ensemble voting classifier based on two different types of classifiers, comprising 11 single classifiers and 4 ensemble classifiers. Performance criteria of the classifiers were based on the overall accuracy, training time, and testing time. The analysis of the experimental data revealed several interesting results. First, for the combination of single and ensemble classifiers, ensemble classifiers with majority voting of Random Forest and Support Vector Machine RBF kernel were the most effective classifiers, attaining high overall accuracy. Second, for the combination of two single classifiers, Multilayer Perceptron and k-Nearest Neighbor attained high overall accuracy, rendering them as the most effective classifiers in this category of classifiers. Third, there were trade-offs between performance measures, as increased overall accuracy was accompanied by longer training and testing time in the performance of such classifiers as both of voting-based ensemble classifiers increased significantly

Title:	ENERGY-EFFICIENT QOE-AWARE DESKTOP DELIVERY SCHEME FOR DESKTOP AS A SERVICE IN MOBILE CLOUD COMPUTING
Author:	XUAN-QUI PHAM, CHOONG SEON HONG, EUI-NAM HUH
Abstract:	Recently, mobile cloud computing has emerged as the state-of-the-art mobile service provisioning. As one of cloud computing service categories, Desktop as a Service (DaaS) enables mobile users to access their virtual desktop in the cloud with any DaaS clients, such as smartphones, tablets. A desktop delivery protocol is responsible for providing the communication channels through the network between the DaaS client and the DaaS platform in order to deliver display updates and other interaction information. There are many challenges in developing a desktop delivery protocol. In order to guarantee the Quality of Experience (QoE) of users, the protocol needs to maintain display quality when processing many different service requirements. On the other hand, due to the limited capacity of the battery of mobile devices, the protocol should be energy-efficient in the procedure of delivering DaaS. To address these challenges, in this paper, we propose a desktop delivery scheme that takes into account both QoE and energy consumption on mobile devices. Our scheme reasonably uses VNC module and MJPEG module of the hybrid remote display protocol (HRDP) to deliver display updates. The experimental results demonstrate that the proposed scheme can provide good display quality of different kinds of service to mobile clients with low energy consumption.

Title:	MOVING OBJECT DETECTION USING CELL BAESED OPTICAL FLOW FOR STATIC AND DYNAMIC SCENES
Author:	HYOJIN LIM, YEONGYU CHOI, CUONG NGUYEN KHAC, HO-YOUL JUNG
Abstract:	In this paper, we propose a moving object detection method which can give warning to drivers and then help to prevent possible traffic accidents. The proposed method is designed to detect moving objects in both situations when host vehicle is stopping (static scene) and when it is slowly driving (dynamic scene). These situations occur alternately in parking lots. The proposed moving object detection method consists mainly of optical flow estimation, background modeling and clustering steps. Amplitude of motion vector is calculated from optical flow technique and used for background modeling. In order to apply effectively background subtraction to motion vectors, we propose a cell based background modeling which accumulates the amplitudes of every vector within a cell and up-dates adaptive threshold value to classify the given vectors into foreground and background. Four different optical flow estimation techniques are considered. Various cell sizes including 1X1, 4X4, 10X10 and 40X40 are applied. The simulations on four kinds of dynamic scenes and three static scenes show that the proposed method achieves good enough moving object detection performances.

Title:	A RELATIVE EVALUATION OF AESTHETIC VALUE FOR CONTEMPORARY ABSTRACT ART CREATED BY COMPUTER CREATIVITY
Author:	EUN-MI LEE, MI-KYUNG JOO
Abstract:	Research of Computational Creativity is one of the most challenging fields in artificial intelligence of computer systems. Contemporary artists have been created various kinds of visual art based on artificial intelligence such as neural networks, machine learning and so on. However, there is a controversy about whether the artwork created by Computational Creativity has significant aesthetic value against artworks created by humans. In this paper, we evaluate aesthetic value of contemporary abstract artworks created by computer program that Versteeg developed based on neural networks. We relatively analyze the aesthetic value of Computational Creativity against the aesthetic value of human creativity. We conduct experiments with people that 10 pairs of paintings are presented that one is created by Versteegs program and the other is painted by an artist of middle standing. The experimental results show that the relative aesthetic value of artworks created by the computer program is slightly lower than those of artists of middle standing. Also, similar to human artists, we found that Computer Creativity can create masterpiece or failure. As the results created by a human artist fluctuates, Computer Creativity also may create various level of artworks in the view of aesthetic value. Since Computational Creativity research in visual art is in the very early stage, creating artwork by Computational Creativity has potentials to be improved and to surpass humans creativity.

Title:	THE SHORTEST PATH FROM SHORTEST DISTANCE ON A POLYGON MESH
Author:	JINHYUNG CHOI, BO ZHANG, KYOUNGSU OH
Abstract:	We can use a Dijkstra algorithm to calculate shortest paths on a polygon mesh. However, if the number of vertices of a polygon mesh is large, the efficiency of conventional path searching method that using Dijkstra algorithm is low. In order to solve this problem, this paper proposes a method to search shortest distance and path by using the A* algorithm. According to an experiment with the bunny model with 2,503 vertices, the efficiency of searching the shortest path is improved approximately 80% than conventional methods.

Title:	EFFICIENT CONGESTION CONTROL TECHNIQUES FOR RANDOM ACCESS OF MTC DEVICES IN OFDMA SYSTEMS
Author:	JUNG-HYUN KIM, SOON-BAE JI, CHEOLWOO YOU
Abstract:	This paper introduces how to support machine-to-machine (M2M) terminals that send a small data on 3rd generation partnership project (3GPP) long term evolution-advanced (LTE-A) system. Especially, we con-sider the lack of random access channel (RACH) and rapidly increasing average latency for both cellular users and countless M2M devices that also are known as machine type communications (MTC) devices. To resolve the overload on physical random access channel (PRACH), this paper studies how to group numerous MTC devices. We also propose a two-way design of efficient congestion control techniques with adaptive access probability and back-off index according to user-defined types. We can expect to improve the average latency by giving fair access opportunity to cellular users, although they have a disadvantage of access compared to MTC users. The simulations have been done under various assumptions for the validation of proposals. Our proposals can alleviate overload over PRACH as well as the average latency for cellular and M2M users through simulations.

Author:	LEE JAEYEONG, SHIN SUNWOO, KIM CHONGMAN
Abstract:	Unmanned ground vehicle like robot is one of the most effective weapon systems based on leading edge technology in the modern warfare. However, its efficiency is still a difficult question to answer. Especially, measuring the effectiveness of unmanned ground vehicle quantitatively needs a particular simulation framework to handle many different rule based agent modeling procedure. In this paper, we propose a new simulation framework for how to measure the operational effectiveness of unmanned ground vehicle in a small unit combat scenario. The framework is processed with following three phases. At first, we consider all relational factors for input and output variables in communication network environment of all platforms. Secondly, build a simulation model and select a measure of effectiveness based on purpose of the system performance. Thirdly, execute a simulation model and produce MOE in order to do output analysis.

Title:	A STUDY ON THE IMPROVEMENT OF RECENT ON-LINE MEDICAL ADVERTISEMENT
Author:	YOUNG JU JEUN , HYUN WOO KIM
Abstract:	The recent medical advertisement format is gradually expanding online as well as offline. In addition, after the Supreme Court ruling that the pre-censorship of medical advertisement was unconstitutional last year, medical advertisement by on-line are continuously increasing, and medical consumers are expected to suffer from false advertising. Medical advertisements of medical institutions can provide accurate and correct information to medical consumers to make the choice of medical consumers wisely, and there is a net function of improving the quality of medical services through healthy competition among medical institutions. However, the increase in medical advertising has the dysfunctions that can cause infringement of consumer choice right and unfair and excessive competition due to the increase of medical service price, increase of advertising cost, damage of consumers due to false or exaggerated advertisement. Since medical care is closely related to the lives of the people, it requires stronger ethics, compliance and publicity than general advertising. And it is urgent to take measures to minimize the damage of the increasing number of on-line medical advertisements. The purpose of this study is to investigate the status of medical advertisements and compare the regulations of foreign countries with the on-line medical advertisements among the medical advertisements.

Title:	PLATFORM MODEL COMPOSITION FRAMEWORK FOR THE DEVELOPMENT OF REAL-TIME CONTROL SYSTEMS
Author:	SANGSOO PARK
Abstract:	Recent trend imposes stringent requirements on the design of embedded systems, differentiating them from general-purpose computer systems such as power consumption, timeliness, reliability, etc. Traditional platform models based on a single view of the underlying support software and hardware are not adequate for modeling all of the interference between the run-time tasks, resources, and services within a system caused by their behaviors and properties. This is mainly due to the fact that application software is tightly tuned to a particular platform, or it is designed and developed to be platform-specific. To overcome this limitation, a platform modeling framework for model-based software development is proposed by identifying the ranges of acceptable platform properties for application software and by specifying the models of computation with respect to the nonfunctional constraints on the underlying execution platform. Specifically, the focus is a multicore-based compositional platform model with fault tolerance for the developed framework. As a case study, a multicore real-time scheduling algorithm is applied to the framework, and the simulation results demonstrate the efficacy of the usability of the framework for supporting fault tolerance. Our proposed approach outperforms by 8.5% even for very heavy loaded system compared to the existing method.

Title:	YESWEB: A CONCISE WEB DEVELOPMENT FRAMEWORK BASED ON HASKELL
Author:	XIAO LIU, YEONEO KIM, SUGWOO BYUN, GYUN WOO
Abstract:	This paper presents YesWeb, an improved framework of Yesod. Yesod is a well-known web-development framework written in Haskell. However, the syntax of it is somewhat verbose and not familiar to those who are not accustomed in functional programming. In contrast with Yesod, YesWeb allows the user to create a web system in a more concise way with a familiar programming syntax. Further, YesWeb takes the full advantage of the many-core architectures to get high performance of parallel computing. Still, Ye-sWeb does not lose the advantages of valuable Haskell features including the type-safety, the modularity, and the parallelism and concurrency. To demonstrate the effectiveness of YesWeb, we have developed a blog application using YesWeb. The result shows that the performance of YesWeb is proportional to the number of cores until the workload saturated.

Title:	DESIGN IMPROVEMENT FOR A DIGITAL MANIPULATIVE BLOCK SET, LIBLO THROUGH USABILITY TESTING
Author:	SEUNGYEON CHOI, BIENIL JEON, JAE WAN PARK
Abstract:	Today, ICT is being embedded in everyday objects intended for use with various products and services. In education, digital manipulative blocks are educational tools resulting from the convergence with ICT. However, current blocks are not suitable to create various kinetic forms, so new digital operation blocks are needed to create various kinetic forms. Liblo is a set of digital manipulative block with built-in ICT. We are developing the Liblo as a long term project. In previous studies, we designed and developed the first prototype of Liblo. This research aims to improve our Liblo design based on design feedback from usability tests. In this paper, we present how to apply the usability testing in order to improve the Liblo design and finally propose newly re-designed Liblo. Currently, we are developing the newly re-designed Liblo. In further research, we will provide developmental experiences of the new Liblo and how to evaluate it. This study contributes to designers or/and developers who are developing digital manipulative block sets by guiding Liblo through the design improvement process.

Title:	AN APPROACH TO IMPROVING THE SCALABILITY OF PARALLEL HASKELL PROGRAMS
Author:	HWAMOK KIM, JOOWON BYUN, SUGWOO BYUN, GYUN WOO
Abstract:	Though the performance of computer hardware is increasing owing to the many-core architectures, the software counterpart is lack of the proportional throughput. In this situation, functional languages can be one of the alternatives to promote the performance of parallel programs since those languages have an inherent parallelism in evaluating pure expressions without side-effects. Specifically, Haskell is notably popular in parallel programming because it provides easy-to-use parallel constructs based on monads. However, the scalability of parallel programs in Haskell tends to fluctuate as the number of cores is getting increased. The garbage collector is suspected to be the source of this fluctuation because it affects on both the space and the time for the execution of programs. This paper justifies this conjecture using the specific tuning tool, namely GC-Tune. We have tuned the behavior of the garbage collector in the executions of three large-scale parallel programs: the K-means, a maximal independent set, and plagiarism detection programs. As a result, the scalabilities of the programs have been improved by 38%, 21%, and 7%, respec-tively; the fluctuation ranges are also narrowed down by 45%, 30%, and 58%, respectively, compared to the original execution of the programs without any tuning. This result implies that GC-tuning can be an effective method to promote the scalability of parallel Haskell programs. In results, the execution time of parallel programs can also be much accurately estimated.

Title:	HOW IMPLEMENTATION LEVEL OF PL RESPONSE SYSTEM AFFECTS ON CUSTOMERS BUYING INTENTION
Author:	JUNHYEOK SEO, SUNGMIN BAE
Abstract:	In the meantime, Korea has only produced and sold product that were proven safe through various certification systems before market introduction. The safety of these products are being managed through market inspection systems after the products are supplied in the market, through constant safety inspections and recall of defective products. However, in spite of the safety management policies of government agencies and corporations, the damage caused by the distribution of unsecured products constantly occurs and the people are not completely free from the anxiety of the product accidents. Therefore, it is necessary to introduce an evaluation system that regularly checks and improves the level of the company's product liability (PL) response activities. This study used SPSS to analyze exploratory factors and reliability and AMOS to confirm a hypothesis through exploratory factor and path analysis. We found out that only the strategy and technology of companies have significant effects on a consumer's perception and utilization intention, among the detailed implementation plans of PL response system presented in previous research. In addition, consumers' perceptions have a significant effect on consumers' intention to use, and consumers' perception and utilization intention have a significant effect on the purchase intention of a product.

Title:	THE USE OF MOODLE TO ENRICH FLIPPED LEARNING FOR ENGLISH AS A FOREIGN LANGUAGE EDUCATION
Author:	KYEONG-OUK JEONG
Abstract:	The paradigm of education has been changed around the globe because of the recent development of smart technology. Thanks to these changes, various web-based course management systems or instructional approaches have been integrated into classroom learning and teaching in order to inspire the study of digital native young generation. This study investigates university students learning experiences in using Moodle as the online learning management system which is intended to facilitate flipped learning procedures within the context of English as a foreign language (EFL). Moodle is a web-based learning management system with pedagogical approaches based on constructivism, which emphasizes the roles of shared learning communities, learner-centeredness, and social interaction in the learning context. Flipped learning has been introduced as an effective instructional method which can supplement conventional teacher-centered instruction and help to promote learner-centered learning milieu in language classrooms. Along with the use of Moodle as the learning management system, adopting flipped learning as an effective instructional strategy can accomplish the pedagogical paradigm of constructivism. This paper examines a variety of issues about adopting Moodle as an online learning management system and implementing flipped learning in EFL education. This study also scrutinizes how integrating Moodle into flipped classrooms has improved students English language learning and classroom interaction.

Title:	EMOTIONAL MOTION PROTOTYPING FOR A SOCIAL ROBOT UTILIZING A DELTA ROBOT
Author:	BIENIL JEON, JAE WAN PARK
Abstract:	Today, a variety of social robots capable of interacting and communicating with humans has begun to emerge. Existing social robots mainly utilize a voice and/or a small screen for emotionally interacting with humans despite many possibilities of physically expressing emotional motion. Thus, this research aims to build methods for emotional motion prototyping and create a prototype of a social robot based on the kinematics of the Delta robot. For this research, literature related to emotional motions of social robots and humans is explored, and emotional motions of humans is categorized based on six basic human emotions in order to analyze existing social robots. Moreover, through analyzing the cases, we propose methods for emotional motion prototyping. Based on these, a prototype of a social robot is developed based on the kinematics of a Delta robot and is tested. In this paper, we present ways to create emotional motions of social robots and experimental experience of a prototype of a Delta-robot-based social robot. Further work in this research is to develop an actual social robot based on the prototype.

Title:	IMPLEMENTATION OF AN EXPERT SYSTEM FOR FUNDAMENTAL-COSMETICS RECOMMENDATIONS USING PROLOG
Author:	Ye-Jin Kim, Kang-Hee Lee
Abstract:	Nowadays, regardless of sex or age, significant attention is paid to personal appearance, resulting in the ever-increasing spending in the beauty and fashion markets. Especially, great-looking skin is a foremost desire; however, there are various components, forms, and functionalities, and these are diversifying further. The recommended product depends on the user's skin condition, weather exposure, age, and sensitivity. Therefore, this paper proposes an expert system that recommends the most suitable fundamental cosmetics for the user, which is the very first touch point between the cosmetics seller and the user. Accordingly, the advantages of the rule-based expert system and the logic-based language PROLOG are exploited. The system first receives inputs from the user, and then the inference engine makes a suggestion for its recommendation of the fundamental cosmetics that result in the user's satisfaction.

Title:	REVISING PROGRAMS INTERNAL DOCUMENTATION FOR DEVELOPERS SUSTAINING
Author:	NOUH ALHINDAWI, ZIAD SARAIREH, OMAR MEQDADI, OBAIDA M. AL-HAZAIMEH, MOHAMMAD SUBHI AL-BATAH
Abstract:	In software engineering, the developers in order to recognize which ingredients or fragments of any software code that put into practice a definite functionality, they utilize Information Retrieval (IR) methods to mechanically spot the code that implement them. The main contribution of this paper is to study and examine the effects of skipping some textual information, namely, the internal documentations from being integrated when performing source code indexing for locating changes process purposes. In this paper, we performed two experiments over three open systems namely Qt, HippoDraw, and KOFFICE. The first experiment is done with counting the internal documentations when preprocessing the software code for locating changes process, while the other one is when skipping it. We used the standard IR measurements, Recall and Precision, and we computed the Wilcoxon signed-rank test to compare and evaluate the results. The experiments results demonstrate that not all internal documentations should be always considered in the process of locating changes. Cases in point, for the Qt system, the results show that the internal documentations improved the results of locating changes while for HippoDraw and KOFFIC systems, the internal documentations negatively impacted it.

Title:	THE ASSESSMENT OF INFORMATION SYSTEM EFFECTIVENESS IN E-LEARNING, E-COMMERCE AND E-GOVERNMENT CONTEXTS: A CRITICAL REVIEW OF THE LITERATURE
Author:	KAMAL MOHAMMED ALHENDAWI, AHMAD SUHAIMI BAHARUDIN
Abstract:	The assessment of the effectiveness of the Web Information Systems (WIS) is increasingly needed as it significantly contributes to the organizations at organizational and individual levels. Also, in terms of assessment, many recent IS research indicated a literature gap in the conceptualization and completeness of the variables of Delone and Mclean models. For this reason, this study focuses on the critical review of the IS literature, and specially keeps attention on the concept WIS effectiveness at the individual level where the effectiveness is conceptualized in terms of users performance skills. With the emergency of Internet technology, considering the interaction design quality as a determinant of success is highly important. Therefore, this study explores the impact of IS on the employee competencies. A new theoretical framework is also developed to cover the incompleteness problem in the quality factors side by adding a new factor namely interaction design quality. Since this study discusses WIS effectiveness in terms of user professional and interpersonal skills, it is expected that this study would contribute to the empirical studies in the fields of information system management and human resources development.

Title:	PERFORMANCE IMPROVEMENT OF SPEED CONTROL FOR INDUCTION MOTOR BY USING INTELLIGENT OPTIMIZATION TECHNIQUE
Author:	ALI NASSER HUSSAIN, AYMEN KADHIM MOHAISEN
Abstract:	Induction motor is considered as one of the most motors that has many uses in the industrial applications in which requires rapid response and high accuracy of control for wide ranges of speed. In this paper, Field Oriented Control (FOC) method was utilized to achieve high performance of control by separating stator current into two components to control the torque and field, along with Space Vector Pulse Width Modulation (SVPWM) technique to reduce the harmonic of the output signal from the inverter and the best use of the DC voltage. The aim of this paper is to enhance the speed response during incurring of the motor for a sudden change of load torque or reference speed. The PSO technique was used to find the best parameters of the control unit in both the voltage and current controllers of the FOC system in order to improve the motor speed response using two objective functions of MAE and ME. The simulation results of PSO-PI controllers demonstrate the superiority over the trial and error PI controllers for enhancing steady state error, rise time and settling time.
