We are facing the new revolutionary age which industrialism and capitalism have been disappearing at tile transition period of civilization. This revolution means the internet, a communication system that is free from the limits of time and space through the establishment of global network. This research aims at finding how the structure of museums and galleries are designed and expressed in the cyber world. It is also intended to analyse factors of their composition.

As the smartphone and mobile environment develop, the time and space constraints for individual work performance are disappearing. Companies can reduce costs and expand their business quickly through cloud computing. As the use of various cloud expands, the boundaries of users, data, and applications are disappearing. Traditional security approaches based on boundaries (Perimeter) are losing their utility in the cloud environment. This paper describes the limitations of existing network access control (NAC) in a cloud environment and suggests network security technology that complements it. The study explains the SDP and combines SDP(Software Defined Perimeter) to overcome the limitations of NAC, while at the same time explaining its role as a new framework for supporting the cloud environment. The new framework proposed in this paper suggests a software-based network security solution that supports physical and software parts, providing identity-based access control, encrypted segment management, and dynamic policy management, not IP-based.

The materials on the development of modern architecture in Korea are being collected and organized in a systemic fashion. However, this is not the case with the materials relative to interior design. They are gradually disappearing or being lost. In particular, no serious attempt has yet been made to determine the characteristics and historic value of the interior design of the modern bank buildings. The purpose of this study is to trace the disappearing legacy of the interior design of modern bank buildings by learning the inner space arrangements of these buildings and the characteristics of modern interior design in order to determine the historic significance of modern commercial interior design. Banks of relatively large scale were selected for the purpose of this study. They consisted of: Chosun Bank(1911) and its Andong, Wonsan and Cheongjin branches; Chosun Shiksan Banks and its Busan, Daegu and Pyongyang branches; the Busan branch of the 18 Bank; Dongil Bank, Chosun Savings Bank(1935) and their branches. The study focused on the space arrangements and design characteristics of these banks. Although they aimed at modernization in designingtheir interior spaces, the modern bank buildings were not representative of any particular style of interior design. While western style designs were prevalent, eclectic designs incorporating many different styles existed. The characteristics of the interior design of banks of the time included installation of such decorations and use of high quality construction materials for interior and exterior expressing the wealth as to create an aura of credibility for the banks, while the floor arrangements were relatively stereotyped and simplified.

We suggest a novel approach to the tracking of multiple moving objects in image sequence. The tracking of multiple moving objects include some complex problems(crossing (occluding), entering, disappearing, joining, and dividing) for objects identifying. Our method can settle these problems by optimization of a penalty function and movement prediction. It is executable in .eat time processing (more than 30 ㎐) because it is computed by only location data.

At least 15% of the C polykrikoides cells that precipitated to the bottom layer either by the addition of loess or no addition survived for 1 week at all growth phases, rather than disappearing immediately after precipitating. However, no live cells were observed after 20 days, regardless of phase or loess addition. In the exponential phase, the number of C polykrikoides cells increased to >2886 cells/ml after loess was added. However, in the stationary phase, the number of cells did not increase until 18 days. In the exponential phase, those C polykrikoides that survived precipitation caused by scattering loess on cultures did not appear to have the ability to cause red tides again because of the short red tide periods in the field, long lag time after loess addition, and low survival rate after loess addition.

Current city that we live in exist many modern architecture have historical meaning and high value. This modern architecture is disappearing because study - definite thesis of concept, division of the time - of preservation wasn't advanced fully and we have the feeling of being victimzed for Japanese imperialism, in addition to lack of recognition for cultural treasure value. These days, a growing number of people tend to focus on preservation and uses of cultural properties including mordern architectures. Therefore, this study aims to figure out constructive uses of mordern architectures by purposing analysis and preservation methods with a selected architectures which deserve to be conserved.

This paper investigates the effects of the existing sealing methods, such as the conventional atmospheric-pressure sealing method and vacuum sealing, on temporal bright-image sticking. To produce a residual image caused by temporal brightimage sticking, the entire region of a 42-in panel with an Xe-(11%)-He(35%) gas mixture was abruptly changed to a full-white background image after displaying a square-type image at peak luminance for about 60s. From the monitoring of the difference in the display luminance, infrared emission, color temperature, and disappearing time between the cells with and without temporal bright-image sticking, it was observed that the vacuum sealing method contributes to the reduction of temporal bright-image sticking.

The temporal dark- and bright-image sticking phenomena were examined relative to the He contents under 11% Xe content in the 50-in HD and FHD AC-PDPs with a ternary gas mixture (Xe-He-Ne). To compare the temporal dark- and bright-image sticking phenomena under various He contents, the differences in the disappearing time, display luminance, perceived luminance, infrared emission, color coordinate, color temperature, and discharge current before and after discharge were measured under 0, 35, 50, and 70% He contents. It was found that temporal dark- and bright-image sticking were reduced in proportion to the increase in He %. Thus, a high He content contributes to the reduction of temporal dark- and bright-image sticking.

Minimizing the residual impurity level on the MgO layer is the key factor for reducing temporal dark image sticking on bright screen. In this paper, to reduce the residual impurity level on the MgO layer of 50-in. full-HD ac-PDP with He (35%) - Xe (11%) contents, RF-plasma treatments on the MgO layer are adopted under various gases for plasma treatment. As a result of monitoring the difference in the display luminance between the before and after 5-min. sustain discharge with a square-type image at peak luminance, the Ar and Ar>$O_2$ plasma treatments can reduce the temporal dark image sticking on the bright screen in an ac-PDP.
