A color image requires at least three color channels to obtain the full color image. However the image sensor obtains only the intensity of the brightness, that is, three image sensors are required for every pixel to capture the full color image. Since the image sensor is quiet expensive, most of digital still cameras adopt single image sensor array with color filter array (CFA) to reduce the size and the cost. Since the image obtained using single sensor array has only one color component per pixel, we need to reconstruct the missing two color components to obtain the full color image. We call this process as color filter interpolation or demosaicking. In this paper, demosaicking algorithm composed of two large step is proposed. Proposed algorithm is combined with several different algorithms such as Edge-directed demosaicking, Second-order gradients as correction terms, Smooth hue transition Interpolation, etc. The simulation results show that the proposed algorithm performs much better than the state-of-the-art demosaicking algorithms in terms of both subjective and objective qualities.

With advancements in augmented reality technology, attempts to apply it in various fields have increased. With advancements in information technology and a growth in the number of Korean learners in Korea and abroad, there is a growing demand for state-of-the-art Korean learning contents. Because the Korean learning contents developed using augmented reality have been found insufficient, this paper investigates ways to develop better contents. This paper proposes ways to develop learning contents that can increase learners' interest in learning and lead to academic achievement, because the methods of education in Korea are limited to textbook learning and learning through the media. Because of the structure of fairytales and the educational lessons that can be learned from them, Korean learning contents are developed using fairytales. Additionally, Korean contents are designed to implement augmented reality technology, and learners need only have computers, webcams, and markers to make use of it. In consideration of Korean learners who do not have access to augmented reality technology, this paper clarifies that there should be a harmony between existing and new Korean learning contents. On the basis of this study, further studies on Korean education exploring the role of augmented reality should be conducted so that Korean learning contents that use diverse types of augmented reality technology can be will developed.

Due to recent rapid deployment of Internet streaming service and digital broadcasting service, the issue of how to efficiently support streaming workload in so called "Internet Home Appliance" receives prime interests from industry as well as academia. The underlying dilemma is that it may not be feasible to put cutting edge CPU, boards, disks and other peripherals into that type of device. The primary reason is its cost. Usually, Internet Home Appliances has its dedicated usage, e.g. Internet Radio, and thus it does not require high-end CPU nor high-end Va subsystem. The same reasoning applies to I/O subsystem. In Internet Home Appliances dedicated to handle compressed moving picture, it is not equipped with high end SCSI disk with fast rotational speed. Thus, it is mandatory to devise elaborate software algorithm to exploit the available hardware resources and maximize the efficiency of the system. This paper presents our experiences in the design and implementation of a new multimedia file system which can efficiently deliver the required disk bandwidth for a periodic I/O workload. We have implemented the file system on the Linux operating system, and examined itsperformance under streaming I/O workload. The results of the study show that the proposed file system exhibits superior performance than the Linux Ext2 file system under streaming I/O workload. The result of this work not only contribute to advance the state f art file system technology for multimedia streaming but also put forth the software which is readily available and can be deployed. deployed.

Walter Benjamin's unique concept of the aura is mainly presented in his three essays, Little History of Photography(1931), The Work of Art in the Age of Mechanical Reproduction(1935-1939), and On Some Motifs in Baudelaire(1939), whereas the studies on this concept are principally conducted on the basis of the first two essays. But considering Benjamin elaborated the concept through Baudelaire studies, the aura needs to be reexamined on the axis of "On Some Motifs in Baudelaire". He approached Baudelaire studies in one of the essential items for The Arcades Project at first. These studies acquired a new prospect soon after he mapped out these studies for an independent book in 1938. His Baudelaire studies come to fruition in On Some Motifs in Baudelaire, written one year after The Paris of the Second Empire in Baudelaire(1938). For Benjamin, Baudelaire is not only a poet who sharply testified to the age of the decay of aura, but also the one who elaborated new poetic motifs such as the metropolis, the crowd: the poet searched for his poems in the crowd of the metropolis, by accepting as poetic nourishment all sorts of experiences of the impact of daily occurrunces in Paris. In On Some Motifs in Baudelaire, the aura is defined as the response of a gaze, that is, the capability to gaze on something. It is principally a poetic capacity to give the capability of opening the eyes to an animal, or even to an inanimate object. If a gaze is responded by the other for which the gaze is placed upon, we experience the other's own aura. The media of the mechanical reproduction (such as the photography, the film) give rise to the decay of aura, because the expectation of returning one's gaze becomes frustrated from the outset.

We see many images every day, some of these images are stored in memory, and the majority are immersed in the unconscious world. Visual elements are seen by personal attention or by visual or biological attention factors. Specific and clear discovery of this visual attention has not yet been made. However, there is an interesting discussion of this visual attention in the fields of interior, design, visual perception, advertising, and psychology. Advertising photographers are expected to produce what their work will have on viewers and consumers. However, the adjustment of subject, exposure, color, or post-production, which could have a visual effect on the consumer, was determined only by the photographer's senses rather than the experimental verification. The advertisement photographs provide a specific image related to the object to be advertised and deliver a certain message. Therefore, it is necessary to understand the effect of the image in a certain visual way. According to previous studies, there are two major factors that affect the visual impression of the viewer. One is the factor depending on the type and content of the subject and the other is the factor about the density and color of the subject. The purpose of this study is to investigate the meaningful changes in the visual perception depending on the shape, content, color and tone of the subject, which can be called the main subject, And to analyze the effects of I will study some implications of visual elements through various analyzes.

This study examined whether there are differences in the empathic ability and emotional intelligence by college students' counseling course-taking experience and major. The research subjects were 313 college students, and an independent sample t-test, one-way ANOVA, and Duncan post-hoc test were conducted for hypothesis testing. A difference in empathic ability was observed according to the students' sex, major, and counseling course-taking experience. A difference in emotional intelligence according to their sex and counseling course-taking experience was noted. Empathic ability was higher in females than in males, higher in the school of social sciences than in the school of science and technology, and higher in those who had counseling education than in those who did not. Emotional intelligence was higher in women than in men, and higher in students who had counseling education than in those who did not. Consequently, the effectiveness of counseling education was confirmed. On the other hand, a limitation of theoretical education was found in that there was no difference in emotional intelligence according to the major. Although empathic ability can be improved by education, the current curriculum has not improved it. This study has significance that it emphasizes the need for supplementing the curriculum, like practice or utilizing art media.

How does a Convergence program affect the mathematics creativity and convergence talent of fifth grade student in elementary school? The subjects in this study were 16 students in fifth-grade class in elementary school located in Songpa-gu, Seoul. A Convergence program was developed using the integrated unit design process chose the concept of congruence and symmetryas its topic. The developed program consisted of a total 12 class activities plan, lesson plans for 5 activities. Mathematics creativity test, a test on affective domain related with convergence talent measurement were carried out before and after the application of the developed program so as to analyze the its effects. In addition, students' satisfaction for the developed program was investigated by a questionnaire. The results of this study were as follows: First, A convergence program should be developed using the integrated unit design process to avoid focusing on the content of any one subject area. The program for teaching of congruence and symmetry should be considered students' learning style and their preferences for media. Second, the convergence program improved the students' mathematical creativity and convergence talent. Among the sub-factors of mathematical creativity, originality was especially improved by this program. Students thought that the program is good for their creativity. Plus, this program use two subject class, Math and Art, so student do not think about one subject but focus on topic 'congruence and symmetry'. It help students to develop their convergence talent.

On Kawara's works are not only artworks but are also his personal daily records. He produced many artworks whose theme centered on his everyday life, a plan that he had precisely made. He selected several specific themes from his daily life: when and where he met someone, what he read, and where he traveled. Kawara constantly recorded his daily life using various types of unconventional medium: maps, postcards, and telegrams. Although he was occupied with recording his everyday life, he was also active in forming public opinions on various issues through social media. Kawara's works, which exhibit a distinctive characteristic of himself, could be classified as individual records because it includes an individual's daily life and selected issues. His artworks express concern for or expose the irrationality of his society, which encourages ordinary people to let their voices be heard and take part in public affairs. Thus, his works function not just as art but also as precious historical records.
