Access to public facilities such as substations, dams and railway facilities is strictly controlled, and unmanned surveillance equipment has been introduced and operated recently due to the development of IT technology and the government's cost reduction policy. However, if an unmanned surveillance system is broken, surveillance space, information leakage caused by intruders, and damage to facilities may occur. Also, it is necessary to check periodical visit by the manager in order to check the surveillance facilities, which causes additional management costs. In order to solve this problem, we designed a system to check the operation status of the unmanned monitoring facility in real time, attempt to recover automatically when a problem occurs, and notify the administrator of the problem. The designed system consists of an NVR that receives and judges information such as image, sound, and lighting condition, and a control device that detects and restores the state of the unmanned monitoring facility. The system proposed in this paper is expected to contribute to the improvement of the economic efficiency due to the minimization of surveillance space due to the failure of the unmanned monitoring facility and the reduction of the inspection cost.

Tunnel sections on the expressway are different from rest of sections on the expressway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Thus, this study tried to find out qualitative factors affecting speed reduction in tunnel sections based on questionnaire surveys and its analysis in tunnel sections selected by taking consideration of diverse conditions. Analysis showed that factors concerning tunnel configuration (lane width, shoulder width, and tunnel length) related to very long tunnels increasingly popular recently had some effects on reduced speed inside of tunnels. It appeared that visual environment such as visibility of tunnel entrance had an impact in speed reduction and vehicle speed tended to change according to lighting illumination level inside of tunnels. It is expected that continual investment would be made in technological development related to expressway tunnel design and service improvement based on this study.

It can gain both the electric energy production and disperse of light at the same time if DSSC is applied in the building as window system. It means to help facade design and to be used in lighting, heating, cooling energy directly by applicating DSSC BIPV window that is possible to daylighting and materialization of color. For this, optical characteristics analysis that is basic step must take precedence. So, basic databases of DSSC are builded and optical performances according to the double and triple glazing are evaluated by analyzing spectral data of various colored DSSC. As a result, Green(4) has the highest visible transmittance that is 28.8%, and Blue(3) has the lowest that is 0.3%. And, in case of optical performance of Green(4) depending on the incidence angle, SHGC and Tsol are decreased sharply from more than $60^{\circ}C$. Finally, It is judged that Red(4), Green(1), (4), Blue(4) are suitable for application in office building because visible transmittance is high and solar heat gain coefficient is low relatively in spite of composing to double and triple glazing.

The purpose of this study is to find out the characteristics of landscape details in representing symbolic images in memorials on the themes of war, tragedy, and the democratization movement. In considering the characteristics of memorial landscapes, the researcher divided the characteristics of landscape details into 3 analysis categories. They are the symbolic application of landscape elements, the embodiment of landscape details, and the organization of landscape details to represent symbolic images, for example, memory, mourning, reflection, healing, glory, and identity. Among details in 24 memorials designed in or after 1970. 133 symbolic details were selected including 64 items in Korea. The analysis revealed that among 30 elements used by designers for memorialization, walls, ponds, sculptures were used more often than other elements in representing the meaning of mourning, reflection, and healing that are the basic function of memorial. In regard to detail form, the designers used basic shapes like circles, squares and rectangles, horizontal and vertical lines to heighten the symbolic effect of shapes in confined form. Stone and water utilized from nature were also used as main materials because of their materiality meaning of death, eternity, life, and healing. The techniques of using lighting, fire, and sound were introduced to make details more effective. Details were organized in harmony and repetition to represent the flew of time and space in symbolic images. The study identified the following characteristics of memorial landscapes in Korea that were different from other country first, in designing memorials, most designers in Korea have been more focused on the organization of space than the details in memorials, and so, they have been neglecting to deliver symbolic image through detail design, while depending mainly on the introduction of art works. Lastly, because they introduced traditional elements which have little relation with the symbolic image needed, there have been many details which inaccurately represent symbolic meanings.

In San Francisco, two new museums were recently built in 1995 and 2005. The one is San Francisco Museum of Modern Art designed by Mario Botta and the other is De Young Museum designed by Jacques Herzog & Pierre de Meuron. The urban settings for the museums are compared with each other and theories of the architects are evolved on different branches in the modernist trends. The theories and settings are followed by the representation in the forms, facades, interior spaces and towers. SFMOMA is located on the SoMa area, which was recently developed into a cultural urban core with Moscone Center and Buena Yerba Garden. De Young Museum was rebuilt in the old museum site in the Golden Gate Park. The one is on the context of urban artefacts and the other on the context of natural artefacts. To Botta, the museum in today's city plays a role analogous to that of the cathedral of yesterday. It is a place of common encounter and confrontation. The volume of SFMOMA which is geometrical and symmetric with double pylons. The frontality on the street and public green open space and the axiality of SFMOMA runs through the Buena Yerba Garden over Buena Yerba Center for the Arts are reminded us of an urban core with a religious monument and a city square. The staircase with grandiose design in the atrium seems to work as an altar with lighting from skylight above enhancing the liturgical ambiance. De Young Museum is shaped in a rectangle with long narrow courtyards. Three bands of volumes are juxtaposed and the nature flows into the museum corridors and galleries. The tower is distorted so as to be aligned to the street grids of the surrounding area. The copper panel of De Young Museum and natural context evoke modern concept of "machine in the garden". The two museums from different pedigrees of Modern Architecture are now major landmarks of SF and urban expressions for the 21st century.

The audience of the performing arts enacted on the stage appreciate acting of the characters in a play to understand its plot, identify with the characters, and comprehend the message and subject matters of the play. Stage make-up in particular should assist audience in comprehending the story without overpowering or distracting the script. Stage make-up is a crucial means to visualize occupation, class, personality, and age of the characters. Thus it is an essential means in producing a high quality performance. The aim of the study is to examine character-emphasis make-up for a play by reviewing theories on the concepts and methods of the stage make-up. The methodology of the study was to analyze character make-up of the adopted play The Madwoman of Chaillot (La Folle de Chaillot) translated from the original French, as a case study. The technique and features of the character make-up of the play were examined, and functions of each factor of the character make-up depending on a role were also examined. The results of the study are as follows. The stage make-up for creating and expressing a distinctive personality of the characters in a play must integrate environmental factors external to a performance such as lighting and scale of a venue. Moreover the stage make-up must adopt and reconstruct internal factors of the play such as interpretation of the original work, subject matters, interpretation of the script, character analysis based on the discussion with a director, and design setting.
