In this paper, we propose deep convolutional neural network(CNN) with bottleneck structure which improves the performance of earthquake classification. In order to address all possible forms of earthquakes including micro-earthquakes and artificial-earthquakes as well as large earthquakes, we need a representation and classifier that can effectively discriminate seismic waveforms in adverse conditions. In particular, to robustly classify seismic waveforms even in low snr, a deep CNN with 1x1 convolution bottleneck structure is proposed in raw seismic waveforms. The representative experimental results show that the proposed method is effective for noisy seismic waveforms and outperforms the previous state-of-the art methods on domestic earthquake database.

This study emphasizes users' participation, a living-transforming visuality, as users have appeared to be a central element of landscape design but ignored before. Also this study tries to propose meaning of extended visuality in contemporary landscape design on the basis of visual criticism on simple perception-and contemplations convention-based landscape design. For these purposes, this study reviews characteristics of visual changes appeared in modern reductionist paintings. In other words, arts can be interpreted in polysemous ways through bodies' experience. Deconstructive concepts derived from the theoretical reviews can be categorized into three including the participation of the users' bodies from a contemplative point of view, textuality and intertextuality, and experiences from works. Those concepts were used to criticize the previous discourse on landscape designs and to analyze various issues in the theories, themes and techniques in contemporary landscape design. The significance of the expanded visuality in contemporary landscape design is that it brings the users' voluntary participation. This structure can serve as a tool to obtain the users' perceptive effects. At the same time, it can be regarded as a process of establishing the relationships between the users and the works. Thus emphasis is placed not only on the influences of the effects structure of the works themselves, but also on the many different dimensions related to the users' bodies. It implies that the meaning of design is not determined by the designer but a product resulted from the voluntary relationships between users and works. These findings lead to ambiguous distinctions between arts everyday life, and eventually to the end of the concepts of formative dichotomous aesthetics and their effectiveness. Finding of this study call for not only redefining the space where landscape design is created and communicated, but also reconsidering the concepts of landscape design and its ontological meanings.

The use of colors plays an important role in the field of space design. The selection of proper colors influences on people who use space by making the most of the psychological and physical functions of colors. Especially, the medical space is relatively more important than other indoor spaces in the selection of colors. The medical space has to be something to do with diversity and functions, and at the same time with stability and quietude, as well as the space with general convenient facilities. Color is not only related to the expression but also to the distinction of things and the existence. It also functions as a visual language. Human beings depend heavily on the function of color as a visual language. According to previous studies, human beings depend on color by 80% of the whole range of eyesight. Thus, color is an important factor in recognizing things and space. For example, in hospital, it Is very important to apply proper colors to various medical treatment spaces for the sake of patients' rest and healing. Various colors which do not consider the function of patients' rest and healing may make the space confusing against the change of space and structure. It is also important to apply colors to the change of space and structure. Another key point that I would like to make is that color has visual, direct and physical influence on the human body. For example, the color red with long wavelength serves to regulate body temperature. Research on the color scheme for hospitals should consider both physical and psychological factors. That is why the research should be carried out in depth through continuous clinical demonstration. The present research aims to outline color planning.

Inspection and shape measurement of three-dimensional objects are widely needed in industries for quality monitoring and control. A number of visual or optical technologies have been successfully applied to measure three-dimensional surfaces. However, those conventional visual or optical methods have inherent shortcomings such as occlusion and variant surface reflection. X-ray vision system can be a good solution to these conventional problems, since we can extract the volume information including both the surface geometry and the inner structure of any objects. In the x-ray system, the surface condition of an object, whether it is lambertian or specular, does not affect the inherent characteristics of its x-ray images. In this paper, we propose a three-dimensional x-ray imaging method to reconstruct a three dimensional structure of an object out of two dimensional x-ray image sets. To achieve this by the proposed method, two or more x-ray images projected from different views are needed. Once these images are acquired, the simultaneous algebraic reconstruction technique(SART) is usually utilized. Since the existing SART algorithms have several shortcomings such as low performance in convergence and different convergence within the reconstruction volume of interest, an advanced SART algorithm named as USART(uniform SART) is proposed to avoid such shortcomings and improve the reconstruction performance. Because, each voxel within the volume is equally weighted to update instantaneous value of its internal density, it can achieve uniform convergence property of the reconstructed volume. The algorithm is simulated on various shapes of objects such as a pyramid, a hemisphere and a BGA model. Based on simulation results the performance of the proposed method is compared with that of the conventional SART method.

The Fourth Industrial Revolution has differentiated technologies such as artificial intelligence, IoT(Internet of things), big data, and mobile. As the civilization develops more and more, humanity enjoy the cultural activities more than economic activity for the food and shelter. The platform structure based on the advanced information technology of the present will expand the cultural contents area in a variety of ways. Cultural contents respond sensitively to changes in consumer and will be useful experiences of human activities. Therefore, it should be noted again that the contents industry should not be limited to the discussion of the application of the fourth technology, but should be produced with emphasis on useful experiences of human being. In other words, the discussion of human activities around cultural contents should be focused on how to apply beyond the use of fourth industrial technology. Therefore, it is necessary to analyze the basis of the successful storytelling of the planning stage to connect the fourth industrial technology and human useful experience as a method for developing cultural contents, and to build and propose a model as a strategic method. This study analyzes domestic and foreign cases made by using big data among the visual contents which show continuous increase of consumption among culture industry field, and draws success factors and limit points. Next, we extract what is the successful matching factor that influenced consumer 's consciousness, and find out that the structure of culture prototype has been applied in the long history of mankind, and presents it as a storytelling model. Through the above research, this study aims to present a new interpretation and creative activity of cultural contents by presenting a storytelling model as a methodology for connecting creative knowledge, away from the general interpretation of social phenomenon applied with big data.

자연은 끊임없이 신비한 산물들을 대량생산해내는 만물의 공장이며, 그 산물들은 끊임없이 변화하고 있다. 또한 자연은 인간이 살아가는 환경을 둘러싼 미적 아이디어를 끊임없이 제공한다. 그러므로 인간은 자연을 대상으로 시각적 관찰을 통해 표현하고자 하는 자연스런 충동에 따른 조형을 추구하게 된다. 자연에 대해 인간이 얻을 수 있는 미적 체험은 그 대상에 대하여 시각적으로 연구할 때, 연상에 따른 형상들을 의식적으로 떠올릴 수 있게 해주는 미학적 변형의 원천인 것이다. 수없이 변화된 자연물과 마찬가지로 의식적으로 경험되는 인 공의 산업 생산물은 자연물과 구조적, 형태적 질을 공유하며 조형적 균형을 위한 의미를 갖게 된다. 자연을 관찰하여 질서나 원리를 통해 디자인에 적용시키고자한 시도는 바우하우스 이후 디자인의 한 방법으로서 부분적으로 실천되어 왔지만, 자연에 대한 연구과정이 서로 분산된 영역에서 진행되어왔다. 최근에 이르러서 이러한 연구는 관련 분야간에 복합되는 입장에서 매우 중요시되고 있다. 따라서 자연유기체의 다양한 범주들을 본 연구에서는 단지 부분적으로 제품디자인 측면에서 고찰하지만, 종합적으로 디자인학적 조형성과 자연유기체의 조형학적 접근은 기본적으로 중요한 것이라 생각하여 본 소고에서 고찰해 보고자 한다.

Icon conveys symbolic information which they have become ubiquitous as main element of GUI. However, users often cannot intuitively understand its functional meanings. Icon has to be designed for users to easily understand functional meanings. In order to evaluate icon, the spreading activation model can be used to effectively understand the process of information retrieval. In asymmetric spreading activation model is that in the two nodes the degree of spreading activation is different according to direction. Thus, asymmetric spreading activation theory was performed evaluating the strength of association when users see visual image to associate their verbal meaning (visual image - verbal meaning pair) and users see verbal meaning to associate their visual image (verbal meaning - visual image pair). According to the direction, this study hypothesizes that the well-designed icons have symmetric relationship rather than asymmetric relationship between the two pairs. The strength of association is measured through the reaction time and the accuracy rate. In performing SAT (spreading activation test), the ten icons were selected as word processing software icons. After first SAT, newly designed icons were developed based on Korean mental model, and second SAT was conducted using them. The results showed that the accuracy rate of newly designed icon has been improved. Also there is significant difference of reaction time between current icons and newly designed icons. Well-designed icon is confirmed that the strength of association relationship arises symmetrically rather than asymmetrically between the two pairs. User centered icons could be designed by improving the strength of association between the two pairs. Asymmetric SAT evaluates the strength of the association between the visual image and the verbal meanings to contribute to the development of icon which it related to human's association structure.
