In this paper, we introduce extended problems of Tower of Hanoi (ToH) and propose a novel visualization method to express a state space of ToH. As for the extended problems, we introduce multi-peg ToH, multi-stack ToH, and regular state ToH. The novel visualization method in this paper is a natural extension of Hanoi graph visualization. In the proposed method, we assign one Cartesian coordinate point per each disk to provide an unified visualization that the marks on a link and the changes of a state should correspond with a peg position of a disk. Compared with Hanoi graph, the generated graph by the proposed method is isomorphic if we remove links of forbidden move, which indicates that our method is a generalization of Hanoi graph and thus is more expressive. To help the understanding of the readers, we show the generated graphs by our method when the number of disks is 2 and 3.

Domain Analysis is an activity to identify commonalities and variabilities which similar application areas in order to reuse analyzed information easily in new software construction. Most of domain analysis output is represented by various diagrams without common standard, and its manual reuses result in low reusability. Domain analysis language can be used to represent domain analysis information and make it possible to automate reuse and test the specifications. In this paper we designed and implemented a processor to reuse domain analysis information represented by domain analysis language and applied our approach to a rental domain and got new specification instances. In addition, we compared reuse of a data flow diagramming tool with reuse of a domain information processor and found combining and found combining of each approach can increase the reusability of both.

Cartoons exhibit contents and images and deliver them to readers by repeating frames. Frames embody the cross sectional factors of space-time, and the repetition of frames makes those cross sectional factors into a continuous flow. The gutter, which exists between frames, takes the role to make the continuous flow link smoothly, and at the beginning stage of the gutter, the operating of the gutter was usually passive by the frame meanings. However, the gutter is not just a medium for linking the frames, but is an efficient participation device for creating new expression methods of cartoon organization. By producing new directing methods for cartoon organization, the distinctive functions of the gutter have been kept alive with cartoon history. The distinctive functions of the gutter can be divided largely into transition function, reminiscence function, speech balloon function, pen function, and decorative function. And those functions perform actively as direct expression method of the gutter. When those functional methods are expressed by the author's intention and the frequency of them is generalized according to described contents, using each author's individual differences can suggest direction for new directing organization of cartoons.

The growth of Web comics is very noticeable in Korean comic market as the 21st century is entered. In amongst these1 trends, the scroll comics had established it self as one of the main stream form for expression, outside the form of the traditional published comics, so it is providing a new visual experience for the readers. The scroll method uses the large vertical space that is uncomparable to the column compartment of the printed comics, and its uses of animation-like techniques, innovative partitioning, flob styles and narration partition positioning, the limitless canvas and the scroll bar of the web page, is leading the digital comic age. However, it is still very uncertain whether the 'scroll comics' will still be valid in the age of Web2.0. It is concerning that even though there are limitless potential in the realms of digital and web, the web comics seem to be bound to one particular medium, 'scroll'. In this report, the form of expression in the scroll centered web comics will be analyzed, and based on this, the future evolution of digital comics shall be investigated.

This study aims to analyze typographic expressions used in recent fashion trends from the perspective of conceptual art and thus identify a variety of meanings. Towards this end, theoretical considerations were made vis-à-vis the main concepts of research, such as typography and conceptual art, and the ready-made, documentation, intervention and language, which are the expressive features of conceptual art, were applied to fashion typography as analytical frameworks. The results are as follows. The ready-made appears in a way that borrows or transforms the visual identity of other brands, and documentation is utilized in a way that lays tautological or contradictory texts together. Intervention arises, while leading to more complex layers of meaning when borrowing the visual identity of the brand, which is conceptually irrelevant. The language is expressed as statements about contemporary social issues, such as environmental protection, ethical consumption and gender problems. Based on the findings of this study, it can be confirmed that in fashion design, typography serves as an effective marketing tool and a medium of social statements. Moreover, it can expand into the possibility of generating new meanings as a novel way of visual expression.

In this study, we contemplated types, essence, characteristics of text data which is material for visual expression of text visualization part of data visualization research and also analysed the multidirectional means of expressive approach for it. Studies of text visualization are spread dramastically under the influence of computer development, open data, wide use of visualization tools, etc. For these reasons, text visualization works have been creating as art works or output of research through various inter-discipline convergent research with engineering, art, humanities, sociology, etc. Nevertheless the theoretical studies on text data itself and its visualization, and also systematic analysis of its approach are rarely made. Data is target of understanding and interpretation, and it has infinite information and possibility with process and approach for it. Considering the attainable status of data in future human society, text visualization which is convergent academic field of study starting with understanding and interpretation of data needs further methodological research and theoretical accumulate.

Existing art, media art, accompanied by a new path of awareness and perception instrumentalized by the human body, creating a new way to watch the interaction is proposed. Western art way to create visual images of the point cloud that represented a form that is similar to the Pointage. This traditional painting techniques using digital technology means reconfiguration. In this paper, a new appreciation of fusion of aesthetic elements and digital technology, making the point cloud in the form of video. And this holographic film projection of the spectator, and gestures to interact with the video content is presented. A Process of making contents is intent planning, content creation, content production point cloud in the form of image, 3D gestures for interaction design process, go through the process of holographic film projection. Visual and experiential content of memory recall process takes place in the consciousness of the people expressed. Complete the process of memory recall, uncertain memories, memories materialized, recalled. Uncertain remember the vague shapes of the point cloud in the form of an image represented by the image. As embodied memories through the act of interaction to manipulate images recall is complete.

A series of images whose sized and resolutions differ by a constant factor are called an image pyramid. Because the images at high levels are small, large object can be detected on high levels of the pyramid at low cost, But in this way, the boundaries of objects are not accurately localized. Therefore the pyramid algorithms extracte the objects by segmentation the constructed image using bottom-up method and description it in an original resolution using inverse bottom-up method. In this paper, we can project an object down to the next lower level of the pyramid and apply to the boundary adjustment algorithm at that level to localize it more precisely. We repeat the process at successively lower levels. In this paper, we present a method of boundary adjustment using an image pyramid to obtain optimal boundary. The performance of the proposed algorithm is compared to those of the conventional method in term of subjective quality of object boundary.

Network services, such as teleconferencing, remote diagnostics and education, and CSCW require multicasting. Multicast routing methods can be divided into two categories. One is the shortest path tree method and the other is the minimal Steiner tree method. The latter has an advantage over the former in that only one Steiner tree is needed for a group. However, finding a minimal Steiner tree is an NP-complete problem and it is necessary to find an efficient heuristic algorithm. In this paper, we present an evolutionary optimization method for finding minimal Steiner trees without sacrificing too much computational efforts. In particular, we describe a tree-based genetic encoding scheme which is in sharp constast with binary string representations usually adopted in convetional genetic algorithms. Experiments have been performed to show that the presented method can find optimal Steiner trees for given vetwork configurations. Comparitivie studies have shown that the evolutionary method finds on average a better solution than other conventional heustric algorithms.

The purpose of this study is to improve the interoperability of IFC for the basic data such as the size of member section, length, thickness, reference location, and eccentricity of the structural members. For this, the method to represent the basic data of structural member is proposed. In the proposed method, the most important criteria is the way that engineers recognize and treat the basic data of structural members. Then, in this study, an IFC file is generated based on the proposed method for a simple RC building composed of members and it is examined that the correct basic data can be derived from the IFC file in the way that engineers do in practice. From the results of the examination, the proposed method is expected to improve the interoperability of IFC for the basic data.
