In this paper, the optical properties of the 54[W] LED module have confirmed by changing the angles of LED modules for street light applications. The angle of LED module changed from the $0[^{\circ}]$ to $60[^{\circ}]$ varying by $20[^{\circ}]$ as horizontal direction ${\ominus}_1$. Morever, the angle of LED module changed from the $0[^{\circ}]$ to $15[^{\circ}]$ varying by $5[^{\circ}]$ as vertical direction ${\ominus}_2$. As a result of simulation, the average illumination was about 17[lux] and the overall illuminance uniformity was 0.29 for a 10.39[m] long and 6[m] wide illuminance area at height of 6[m], which is acceptable for street lighting illumination in the Illuminating Engineering Society(IES) standard.

The essence of brand identity is to draw an interrelation between user and brand based on user's desire. The housing cultural center is focused on brand identity for satisfaction of user. The purpose of this study is to inquire out the expression characteristics of brand Identity in housing cultural center according to analyze previous studies and case studies. The results of this study are summarized as follows. 'Uniqueness' is directly expressed through brand name or logo or through brand colors. 'Experience' is expressed as auditive expression through stimulation using a body and providing music. 'Relationship' has provided a communication environment or created relationship with brand by leading interaction with others. 'Estheticism' has increased visual satisfactory level by aesthetically sublimating lighting direction or form. 'Functionality' is expressed by providing various programs through smooth flow plan and grafting with the latest technology. 'Non-dailiness' has affected memory territory by inducing curiosity and astonishment through space modification or new and contrasting direction. The housing cultural center needs to be planned as a space where interaction of user and brand will be initiatively activated sensationally and psychologically by pursuing user-oriented brand identity.

The purpose of this study is to analyze the characteristics of interior space in his design hotel through the analysis of Tony Chi 's work and to present the direction of the design direction of the interior space of the design hotel in the future based on the results. The results are summarized as follows. First, the characteristics of the interior space of Tony Chi are divided into visual balance, repetitive rhythm, symbolic emphasis, exaggerated scale, design harmony, and physical borderlessness. Second, the spatial composition through visual balance was consistently shown in all cases, mainly by arranging elements such as furniture and lighting symmetrically. Third, the spatial composition through repetitive rhythm did not show its characteristics at the beginning of the works, but gradually appeared as repetitive rhythm expression using bold pattern. Fourth, Toni Chi constantly expressed the space composition through symbolic emphasis during the planning of the design hotel. Fifth, the exaggerated scale was mainly used to express the architectural detail vertically according to the height of the ceiling to express a grand space and appear in many works. Sixth, Toni Chi consistently expressed the composition of space through the harmony of design of oriental and western cultures, classical and modern designs in all cases. Seventh. In order to provide curiosity induction and aesthetic experience, spatial composition through physical borderlessness was used.

The concept of sustainable development to preserve natural environment through economy in resources and energy is gradually distinguished since environmental problems as a series of air pollution and global warming take place now. Building occupies more than 1/3 of energy consumption in the whole world. Energy consumption of buildings caused a quick increase in the amount of energy use by air conditioning, which has a lot of effects on exhaustion of fossil energy as well as an increase in environmental load. Therefore, this research intends to suggest characteristics and direction for the designing of acclimatization's housing through the case study on acclimatization's housing. Acclimatization's housing is designed to reduce building load from the designing stage unlike green home or low-energy apartment. Also, factors which are commonly applied to acclimatization's housing are applied complexly by design strategic factors of Heating, Cooling and Lighting. The applied design factors make effects mutually and complexly. In addition, design strategy showed different priority by designing direction.

Lunar permanently shadowed regions (PSRs) never see direct sunlight and are illuminated only by secondary illumination - light reflected from nearby topography. The ShadowCam imaging experiment onboard the Korea Pathfinder Lunar Orbiter is acquiring images of these PSRs. We characterize and discuss the nature of secondary illumination for the Shackleton PSR from ShadowCam radiance-calibrated images. We also use modeling to understand the magnitude and direction of the secondary illumination. Results from our analysis highlight the non-homogeneous, dynamic, and complex nature of PSR secondary lighting. Knowledge of the direction of the secondary illumination is crucial for reli-able interpretation of contrasts observed in ShadowCam images. This preliminary analysis of the floor of Shackleton crater from images acquired over multiple secondary illumination conditions does not reveal indications of exposed surface ice, even though temperatures are constantly below 110K.

This paper proposes a face recognition technique that effectively combines elastic graph matching (EGM) and Fisherface algorithm. EGM as one of dynamic lint architecture uses not only face-shape but also the gray information of image, and Fisherface algorithm as a class specific method is robust about variations such as lighting direction and facial expression. In the proposed face recognition adopting the above two methods, the linear projection per node of an image graph reduces dimensionality of labeled graph vector and provides a feature space to be used effectively for the classification. In comparison with a conventional method, the proposed approach could obtain satisfactory results in the perspectives of recognition rates and speeds. Especially, we could get maximum recognition rate of 99.3% by leaving-one-out method for the experiments with the Yale Face Databases.

Nowadays, natural resource are running out and the level of the environment contamination is getting serious. To solve these problems, each country and institute tend to need many-sided researchs and developments. At this point, especially, there are many coal-mines in Jung-sun and Tae-back where are located in Kangwon province. By the way the abandoned mines cause not only local economy collapse but also environment contamination by submergence of stony mountains. The counterplan is positively inquired further examination by the government. Consequently, we hope that the recycle of polymer concrete can reduce the environment contamination, suggest the new direction of Green Design and can be switched over high added value goods. In conclusion, the recycle of polymer concrete will be valuable.

The traffic policy of a city in Korea has brought to many traffic problems by putting emphasis on the only side of mobility in the past that the personal transportation was put first in importance more than the public transportation. As the result of this policy, in the process that the traffic policy of large cities in Korea changes into accessibility, it is shown for re-lighting up the development of the public transportation to be going to be able to get many suggestions in searching for the desirable developing direction of the new means of transportation that will arrive at Korea in the future. Especially, compared with the policy of U.S.A. on the traffic plan that has concentrated on the road and the vehicle, and that of Europe that has put first in the walking and the public transportation system, it is considered as an important thing that the lesson is given to us about what is important for the desirable city development. Transportation can be divided into four; a railroad transportation. a road transportation, a marine transportation, and an aerial transportation.
