Recently, calligraphy has become popular because people focused on emotion. The strokes, dots, swoops, cracks and shading are the calligraphy factors for expressing various emotions such as joy, anger, sorrow, and delight. However, the emotion which is expressed by cracks and shading can be destroyed in the digital work when the calligraphy is used for a variety sizes of prints. Professionals work with high-resolution images which are obtained through the scanner, however normal users should work with low-resolution images taken with the smart phone for calligraphy image editing. We propose a raster image scaling method focused on calligraphy that maintains the emotion with cracks and shading, when normal users use the low-resolution calligraphy images in the digital work. The method recolors aliasing boundary of enlarged rasterized image. When recolored by our method, our method decreases aliasing by using the image gradient method, vivify calligraphy images, and maintains the emotion in cracks and shading by using the alpha value.

In this paper, we propose the smart management technique of applications using fuzzy logic in wireless sensor networks. We consider the intelligent action compared to the classical action that can only be controlled by on and off. The vagueness depends on the places of the sensor nodes, human's character and emotion. In order to control them with the smartness, the proposed technique considers the better performance of applications in wireless sensor networks. We performed the simulations and implementations on sensor nodes and checked out our ideas. The simulation results show that the proposed technique is more reasonable than the classical approach.

The era of the fourth industrial revolution, which will bring about a great wave of change in the 21st century, is the age of super-connection that links humans to humans, objects to objects, and humans to objects. In the smart city and the smart space which are evolving further, emotional engineering is a field of interdisciplinary researches that still attract attention with the development of technology. This paper proposes an emotional object prototype as a possibility of emotional interaction in the relation between human and object. By suggesting emotional objects that produce color changes and movements through the emotional interactions between humans and objects against the current social issue-loneliness of modern people, we have approached the influence of our lives in the relation with objects. It is expected that emotional objects that are approached from the fundamental view will be able to be in our lives as a viable cultural intermediary in our future living space.

In this study, we implemented the emotional light controlling system by using the wheel interface built in the smart-watch devices. Most previous light controlling systems have been adopted the direct switches or smart-phone applications for presenting individual emotion in lighting systems. However, in order to control color properties, these studies have some complicated user-interfaces in systems and limitation to present various color spectrums. Therefore, we need to user-friendly interfaces and functions for controlling properties of the lightning systems such as color, tone, color temperature, brightness, and saturation in detail with the wheel interface built in the smart-watch devices. The system proposed in the study is given to choose the user's selecting the emotional status information for providing the emotional lights. The selectable emotional status such as "stable", "surprise", "tired", "angry", etc. can be among 11 kinds of emotional states. In addition, the designed system processed the user's information such as user's emotional status information, local time, location information.

The kit consists of MP3 Player, remote controller module and ear phone, and are easy to assemble and dismantle. And usability evaluation about MP3 smart Clothing which was developed in this study contains e-textile keypad and a kit. For making the MP3 Smart clothing, e-textile signal line and keypad was developed and a metal connection ring also was manufactured to adhere closely e-textile signal line to keypad. The last products are two kinds of MP3 smart clothing, jacket style of MP3-YSJ(Yonsei Smart Jacket) and safari style of MP3-YSS(Yonsei Smart Safari). Then usability evaluation conducted two times about MP3 smart clothing developed. Usability evaluation is classified by a module evaluation and an item evaluation. The module evaluation measured external appearance, material, a music controller, an ear phone(or a mini speaker) and connector. The item evaluation measured social acceptance, feeling of wearing, utility, easiness of maintenance and safety. The module evaluation described totally positive results in the first usability evaluation about MP3-YSJ 1.0 and MP3-YSS 1.0. The item evaluation shows a lower score in the social acceptance, especially the easiness of connector maintenance and the social acceptance of music-controller in MP3-YSJ 1.0 and MP3-YSS 1.0. The second usability evaluation conducted with improved products by the first usability test results. Results from second item evaluation indicated needs to improve the easiness of connector & music-controller maintenance and the social acceptance of music-controller in MP3-YSJ 2.0. In MP3-YSS 2.0, the easiness of material management and the social acceptance of music controller & connector needed to improvement. In particular, users felt inconvenience in the social acceptance because of e-textile keypad arrangement. To outweigh this disadvantage, further study is needed about keypad interface of the music controller.

The rapid spread of smart devices initiated by the launch of iPhone and the development of state-of-the-art communication technology have opened up a new chapter for today's age, accelerating a paradigm shift. It is defined as 'the smart era' that is characterized by a DNA of mobile. The meaning of the term 'smart' depends on in which field it is used and who uses it, but the term is basically based on 'human being,' namely people. Accordingly, people should take the initiative in this smart era, and what only people can do will become more important for that reason. In addition, there will be a drastic progress in today's technology, which is expected to make human life more convenient and to even make it possible to read human sentiment and emotion. Such social changes have affected education as well, and the education sector is making preparations for the introduction of 'smart education,' as there is a consensus that an absolutely new paradigm shift is mandatory. Smart education is not merely to introduce smart devices, ICT technology and SNS in education. New competent people are required in globalization age, and smart education is to attempt a new education to nurture new competent people. In this study, 4C (that were creativity, collaboration, contents and curation) were suggested as the key factors of smart education, and in which direction smart education should be led in our country was discussed.

Since the domestic introduction of iPhone in 2009, use of smartphones rapidly increased and many tasks, previously performed by various devices, are now performed by smartphones. In this process the importance of reading little text using small smartphone screen has become highly significant. This research tested how display factors of smartphone (pixel density, sub-pixel structure, luminance) and environmental factor (illumination) affect legibility related discomfort in text reading. The results indicated that legibility related discomfort is largely affected by pixel density, where people experience inconvenience when the pixel density becomes lower than 300 PPI. Illumination has limited effect on legibility related discomfort. Participants reported more legibility related discomfort when stimulus presented in various levels of illumination rather than single illumination level. Sub-pixel structure and luminance did not affected legibility related discomfort. Based on the results we suggest lower limit resolution of smart devices (smartphones, tablet computers) of different sizes for text legibility.
