With rapidly changing multimedia environment, various artistic changes and digitalized up-to-date social infra, urban environment construction based on culture contents has been activated. The large image in front of urban building that is expressed as media-façade, increasing rapidly in a recent period, is not a new thing at all. In addition, IT technology molten in city space is testing the possibility of new media through the meeting with architecture. However, unlike its infra enlargement, the definition about media-façade is not clear so the system was constructed in a level of night lightscape or outdoor image advertisement. The purpose of this guideline is the regulation from the negative aspect rather than the possibility of various visual, artistic media expressions. Therefore, it could not show essential concept of media-façade. Moreover, most of companies or building owners focus on short-term profit and marketing effect rather than prepare various contents so they can not use constructed infra properly. After all, in many cases, they discolor the meaning of media-façade. This paper is a pilot study to grasp the current definition of media-façade to construct right guideline of media-façade. On the basis of this study, it will prepare academic definition of media-façade and construct the guideline for design evaluation.

This study suggests direction of new ordinance establishment for the future national application of Low Impact Development(LID) by analyzing current LID-related regulations of local governments, substantial agents to install and maintain a facility, through qualitative and quantitative methodologies. Four key words related to LID were derived from advisory conference and then ninety nine ordinances as the LID-related regulations were extracted to analyze. The study shows that rainwater-related ordinance passed in the middle of 2000s are being merely converted to the law on the promotion and support of water reuse. Regulations on water cycle and LID exist only in three cities nationwide(Seoul City, Suwon City and Namangju City). Interview with administrators of three cities to have LID-related regulations revealed following results. First, both rainwater and water reuse related regulations have not considered regional characteristics such as rainfall intensity, effects of impervious and merely followed guidelines by Ministry of Government Administration and Home Affairs. Second, existing ordinance is confined to specific facilities and thus cannot include the concept of LID which covers land and space utilization. Therefore, for proper application of LID, this study proposes issue of ordinance that resembles Seoul City ordinance and a new guideline that can reflect regional characteristics such as rainfall and location.

This study aims to understand causal relationship among preference factors - preferred design, design image, and design elements-to create interaction between artists and spectators, concerning eating and drinking table decoration which is produced with subjective representation chiefly by virtue of the authors' conceptualization and planning. As an experimental research , face-to-face personal interviews have been made in off-line setting through questionnaires. Acquired information from it has been analyzed, which results are as follows. As harmonious, warm, womanish design image, combination of pink-tone similar colors were preferred. As image adjectives highly related with design preference were 'harmonious and inharmonious' A design factor of 'harmonious' was combination of similar colors, while that of 'inharmonious' was association of mixed colors. It has been found that 'colors' have been an important factor among preference design factors. As above, a new concept for design can be established by using data-based information, along with suggesting a direction for preferred design in the field of eating and drinking table decoration. Furthermore, it will be possible to make a study of new preferred design through evaluation of quantitative spectators in this area. It is expected that such researches could give an opportunity to get satisfactory results from newly experimented designs using quantitative data even in a creative design area, as well as table decoration.

Some artists and scientists in physics and animation originating from research on its form of expression thanks to the rapid development of the example in the late 20th century image production technology integrating existing media feature, perform a re-creation and pop culture content has been recognized as a key factor. animation of the modern emphasis is also commercial and artistic activities as show whether the artist can not be excluded that also target audience. The audience does not want only to receive offers simply 'seeing' and 'hearing' in the animation requires a more indirect mental met. the other side, the director should lead the audience to immerse myself in work as intended mystification induce the world. where a conflict occurs between the audience and the director and The director needs to have its troubleshooting point to 'Technology of the communication'. Which is reduced to 'How will tell,' is technology communication technologies that are abbreviated representations of animation director is accessible to the audience and it is a close relationship between the psychological aspect of audience. Because, the audience is reproduced in a limited space, but he called on the board of directors and the same time the screen, the audience located at reception and the director located at provide. It is given. led force is given to the director. for this reason, The director needs to pay attention to the psychological aspect of audience this can be explained based on psychoanalytic theory. In this paper, "How can you lie to the audience and the director is the same line?" put down logic that is the animation audience under the logic that takes place visually capture phenomenon "selective attention" and sub-concept of "goal-directed selection' and 'stimulus-driven capturel' for theory of psychology. also, Induction device to elicit selective attention of the audience accordingly, let's consider whether and how they apply in animation.

In the recent era of NewSpace, unlike high-reliability satellites of the past, low-reliability satellites are being developed and mass-produced at a lower cost to launch constellations satellites. To achieve cost-effective cluster satellite development, satellite users and developers need to assess the feasibility of maintaining mission performance over the expected lifespan when cluster satellites are launched. Plans for replacements due to random failures should also be established to maintain performance. This study proposed a method for assessing system reliability and availability to maintain mission performance and establish replacement strategies for Earth observation constellation satellites. In this study, a constellation reliability and availability model considering mission performance required for a satellite constellation, situations of satellite backup, and additional ground backups was established. The reliability model was structured based on the concept of a k-out-of-n system and the availability model used a Markov chain model. Based on the proposed reliability model, the minimum number of satellites required to meet mission requirements was defined and satellites needed in orbit during the required mission period to satisfy mission reliability were calculated. This research also analyzed the number of spare satellites in orbit and on the ground required to meet the desired availability during required service period through availability analysis.

The purpose of this study was to review the government's policy on the enhancement of sports facilities for community residents regarding the lack of knowledge surrounding the infrastructure of sports facilities. The government has invested approximately 2.4 trillion won to establish 220 community sports centers, 385 billion won for 194 multi-purpose indoor centers, and 1.3 trillion won for rebuilding 1,870 school outdoor fields. On the other hand, there are problems with the link between the crumb rubber infill on sports fields and cancer, a lack of availability of indoor sports centers, and an increased federal budget deficit. It is the responsibility of government to plan and construct outdoor fields that are large enough to accommodate all people and allow them to play activities. In addition, the guidelines should ensure that the indoor space required for physical activities at each teaching station is large enough to accommodate all students in the class and handle two classes. The government should suggest the federal government guidelines based on a good understanding of the concept of infrastructure in sports facilities. The government also should make efforts to reduce the regulatory powers and provide the community with an autonomous right to plan and construct sports facilities.

A study of the effects of dynamic pile-soil-structure interactions on the response of super- structures, supported by group piles, are presented in this paper. The dynamic impedance functions of single pile generated by soil-pile interactions are obtained and compared among others using the methods proposed by Novak, Gazetas, and Kuhlemeyer, and using the equivalent cantilever method. Group pile effects are also considered by the following approaches : neglecting interaction effects : group efficiency ratio concept : static interaction approach . and dynamic interaction approach. The responses of a nuclear containment structure are obtained by using the elastic half-space analysis, based on the impedance functions mentioned above. Main conclusions drawn from this study are as follows : 1. The numerical results of the impedance functions calculated by each method were quite different : the Novak's was the smallest, and the Kuhlemeyer's the highest. Considering group effects, similar values in each approach were obtained for the stiffness : the difference was very big for the damping. 2. The top displacement of the structure was reduced by 20% or more by pile installations. However, the base shear force, the base moment, and the resonance frequency were increased by more than two times due to stiffening effect of the ground by pile installations. 3. Whether frequency dependant impedence functions or frequency independant functions were used, the responses of the structure were not so much affected by the choice of the impedance functions. 4. The reduction effect of the top displacement increased with the increase of the maximum ground acceleration.

A number of true triaxial tests on rock samples have been conducted since the late 1960 and their results strongly suggest that the intermediate principal stress has a considerable effect on rock strength. Based on these experimental evidence, various 3-D rock failure criteria accounting for the effect of the intermediate principal stress have been proposed. Most of the 3-D failure criteria, however, are focused on the phenomenological description of the rock strength from the true triaxial tests, so that the associated strength parameters have little physical meaning. In order to confirm the likelihood that the intermediate principal stress dependency of rock strength is related to the presence of weak planes and their distribution to the preferred orientation, true triaxial tests are simulated with the transversely isotropic rock model. The conventional Mohr-Coulomb criterion is extended to its anisotropic version by incorporating the concept of microstructure tensor. With the anisotropic Mohr-Coulomb criterion, the critical plane approach is applied to calculate the strength of the transversely isotropic rock model and the orientation of the fracture plane. This investigation hints that the spatial distribution of microstructural planes with respect to the principal stress triad is closely related to the intermediate principal stress dependency of rock strength.
