The smart grid, a new open platform, is a core application for facilitating a creative economy in the era of the Internet of Things (IoT). Advanced Metering Infrastructure (AMI) is one of the components of the smart grid and a two-way communications infrastructure between the main utility operator and customer. The smart meter records consumption of electrical energy and communicates that information back to the utility for monitoring and billing. This paper investigates the impact of a cybersecurity attack on the smart meter. We analyze the cost to the smart grid in the case of a smart meter attack by authorized users based on a high risk scenario from NESCOR. Our findings could be used by policy makers and utility operators to create investment decision-making models for smart grid security.

This research aims to analyze humorous images expressed in 2D graphics fashion illustrations and to propose application of 2D graphics in humorous images for fashion illustrations to suggest a more creative and relevant fashion illustration for contemporary culture. The result of this research were as follows: First, theories on reaction of humor can be classified into Incongruity theory, Superiority theory and Arousal and Relief theory. Humor in visual arts are classified in Visual Parody, Visual Pun, Visual Paradox and Visual Satire. Second, Visual Pun, Visual Parody, and Visual Satire are used for visualizing fashion illustration, and the foundations for many humor images were simple-colored, imaginative, and unreal settings. And it was also found out that the physical proportion of the models generally was 1(head):7(entire body), 1:8, 1:15 and the models were usually laughing and smiling. Tone was usually pastel and vivid, and posture was usually standing-position or sitting-position. Third, based on such results, fashion illustration works of humor image using 2D graphics were created. To concretize the humor image, 'gift' as a concept was chosen. Humor alleviates the tension and stress. It also brings laughter and pleasure to people's lives. Therefore humor image will be an effective way of expanding creativity in modern fashion illustration.

Since the 20th century, there has been a growing interest in the new concept of fractals, a combination of mathematics and art, and the attempt to study the creative spatial aspects of the concept is being made. The purpose of this research is to examine artistic characteristics of fractal dimension and then analyze the types of fractal dimensions expressed in the fashion. Previous literature on fractals and dimension, and visual data on art and fashion collected over the Internet were used for analysis. Fractal dimension refers to the spatial concept of structural dimension of geometrical self-similarity. An analysis of the types of fractals seen in fashion revealed spatial expansion, the repetition in continual figures, superposition accordant to different sizes, and shades of different shapes. The aesthetic characteristics of fractal dimension appearing in fashions were examined based on analyses of fractal dimension types; the inherent characteristics of self-similarity, superimposition, and atypicality were found. Results obtained from this study are expected to be used as basic materials for the application of the design of fractal dimension into various perspectives of fashion.

This study is focusing on typicalized character make-up of TV Drama characters. The purpose of this study is to analyze the interconnections of its images and impressiology concretely, and then reflect on an application approach of impressiology. The aim of make-up lies in not only helping actors to visualize their own external qualities, appropriate the quality of a play, but also audience and spectators to be immersed in the concrete fact of i character person. Impressiology will be a data to give the understanding and sympathy of make-up work. I would like to utilize character make-up based on impressiology for creative and effective make-up techniques, and make it a typicalized character. Also I will examine the horizon of a new make-up technique through character development according to the demandes of the times. As a result of this study, we find that expression method of characteristic character generalized representatively is the common quality of impressiologistc image. Also we see that such a impressioiogistic image is useful for the fundamental basis of character expression method.

We propose a mechanism for monitoring load in quality of service (QoS)-enabled wireless networks and show how it can be used for network management as well as for dynamic pricing. Mobile network traffic, especially video, has grown exponentially over the last few years and it is anticipated that this trend will continue into the future. Driving factors include the availability of new affordable, smart devices, such as smart-phones and tablets, together with the expectation of high quality user experience for video as one would obtain at home. Although new technologies such as long term evolution (LTE) are expected to help satisfy this demand, the fact is that several other mechanisms will be needed to manage overload and congestion in the network. Therefore, the efficient management of the expected huge data traffic demands is critical if operators are to maintain acceptable service quality while making a profit. In the current work, we address this issue by first investigating how the network load can be accurately monitored and then we show how this load metric can then be used to provide creative pricing plans. In addition, we describe its applications to features like traffic offloading and user satisfaction tracking.

New business The e-book industry is creating a convergence of ICT and printing culture. Even so, the system changes is not great in Korea. Global market players are going to creating a membership or community-type business model to take advantage of the terminal, platform, network, but the creative content production in Korea is limited. Since the discussion is limited to such devices or network services most, we suggest the possibility of modeling a multi-faceted. And the development of technology and services platform content is also important as a strategic approach to the development of the e-book industry. Most of all, we propose the application of content, technologies and services are developed.

Technological development are now encouraging new concepts in various fields of design, including material applications. Metal can be considered as the major material that represents modern design and technology since the industrial revolution. The objective of this study was to understand characteristics of metal as design material and various application methods in interior design. This study first examined basic qualities of metal and its history used in architectural design. Secondly, based on three qualities of metal such as physical, chemical, and mechanical the authors have analyzed projects built within recent 10 years regarding aspects of metal qualities, treatments. As results projects that uses a combination of two or more qualities and treatment seem to have a more interesting affects in interior space. Moreover, each affects are related to these four design keyword: visual distortion, de-materialization, hi-technology, and time-concept. The framework developed is hopes to be used as a basic design guideline, where metal is considered not just as a mere interior finish material but as a major creative source and inspiration in interior design.

Identification and discrimination the mathematical giftedness must be based on it's definition and factors. So, there must be considered not only IQ or high ability in mathematical problem solving, but also mathematical creativity and mathematical task commitment. Furthermore, we must relate our ideas with the programs to develop each student's hidden potential not to settle only. This study is focused on the discrimination of the recipients who would like to enter the elementary school level mathematical gifted education program. To fulfill this purpose, I considered the criteria, principles, methods, tools and their application. In this study, I considered three kinds of testing tools. The first was KEDI - WISC personal IQ test, the second is mathematical problem solving ability written test(1st type), and the third was mathematical creativity test(2nd type) which were giving out divergent products. The number of the participant of these tests were 95(5-6 grade). According to the test, students who had ever a prize in the level of national mathematical contest got more statistically significant higher scores on 1st and 2nd type than who had ever not, but they were not prominent on the phases of attitude, creative ability or interest and willing to study from the information of the behavior characteristics test. Using creativity test together with the behavior characteristics test will be more effective and lessen the possibility of exclusion the superior.

The purpose of this study is to explore the possibility of changing students' learning styles and preferred teaching styles after applying the flipped learning method to engineering education. In order to achieve the purpose of this study, literature review and survey study were conducted. The subject of application of the flipped learning method is the 'Creative Problem Solving Methodology' class, which is one of the specialized liberal arts subjects operated for students of the college of engineering at D university in Gyeonggi-do. For the survey study, a tool adapted to the domestic conditions of Kolb's learning style test tool and Felder & Silverman's preferred teaching style test tool was used. In addition, pre- and post-tests were conducted to measure changes in the learning styles and preferred teaching styles. As a result of applying the flipped learning method for one semester, the learning style showed a tendency to change from an accommodative to a divergent learner. In addition, in the case of the preferred teaching styles, it was confirmed that there were statistically significant changes in the organization and the area of participation. Based on these findings, a proposal for a follow-up study was presented.
