This is a study on the construction of the Heungcheon-Temple. The results are follows. 1) The Heungcheon-Temple was anticipated to be the Jeongneung. However, when completed, the Heungcheon-Temple was symbolized Buddhism; moreover, there was a stupa enshrined sarira. The stupa was a land mark in Hanyang. While king Sejong repaired the stupa, it disappeared during the regin of King Jungjong. Before it disappeared the stupa signified a Buddhist event and a rite of good fortune. 2) The stupa was constructed using a double-frame, and there was a stone-stupa in an octagonal multi-layer temple. This single location consisted of a sarira space and a worship space. 3) Buddhist Relic(Sarira) worship was to witness holiness and therefore reics could be moved according to need. It appeared as though Buddhist Relic worship occurred in Southeast Asia. 4) The Heungcheon-Temple stupa was considered a new and superior architectural-symbol to comfort people and recognize the new order of Ming and neo-Confucianism. Therefore, the stupa was a good alternative to politics, religion, and external relations during the early Joseon era.

Nowadays the issue of environmental pollution and ecological destruction is not a simple issue but an important issue to be continuously considered. It is deemed that a study for recycled new materials is immediately required and this study is to analyze features and processing methods of new materials which can be used to interior space. We found the recycled new materials used for space through researching various web sits. And then we analyzed what the base materials are and classified that base materials are whether natural or artificial of the recycled materials. We classified processing methods of the recycled new materials after researching general processing methods. The result of this study would be an important material to the research and development of new finishing materials with consideration of environment and to the research for a guideline of applicable new materials. The results of this study are as follows : First, we could classify widely 2 categories into natural material and artificial material and then 10 subcategories into metal, glass, wood, rubber, stone, plastic, leather or fabric, ceramic, concrete and so on, and analyzed that which material is mostly used and whether it is single material or multiple material. In order to analyze the feature of processing method. Second, we could classify into 4 categories such as junction, surface process, molding, and insert, and found out which processing method is applied based on objects of research. Third, as an analysis result of the recycled new material feature, in order to develop various new materials, it is required to study on combination and application of 2 materials or more rather than single material. Four, as a analysis result of the processing method feature, I would like to suggest that development and application of various processing methods are required. Especially, it is necessary to grope for a way to develop new functional materials for interior space through a systemic research and analysis of processing method of other fields. Furthermore, a way to reuse recycled new materials should be considered in a stage of selection and application of processing method.

Prime Minister Kim tart-song is said to have built this cave temple in the tenth year of the reign of King Kyongdok-wang(742-765) of Unified Shilla(751). The numerous stone Buddhist images in the grotto represent the best Buddhist figure of the Unified Shilla period and of all Korea. The Sokkuram Grotto is composed of the main hall, entrance to the main chamber and antechamber in space. The main hall beyond the small antechamber is round and the ceilling is domed. Within the rotunda sits a majestic Buddha(Amitabha), 3.48m in height and 2.6m in width, carved in granite and facing east. Surrounding the main Seated Buddha are eleven-headed Avalokitesvara Bodhisattva, Manjusri Bodhisattva and the other three Buddhist images, Ten disciples, Buddhist figures in the ten Niches in relief. An eleven-headed Avalokltesvara Bodhisattva of boundless mercy is sculptured on the wall behind the main Seated Buddha. Further guarding the Buddha are ten standing Arhans of the Disciples of Buddha. Next, two Devas. one on each side, stand guard. Two Bodhisattvas are the saints who are next to the Seated Buddha in importance, also one on each side. And, There are ten niches around the dome. They contain seven seated Bodhisattvas and one Vimalakirti(the name of a famous lay disciple of the Buddha). Two niches are empty. Consequently, there are total thirty-eight Buddhist images in the Sokkuram cave temple. The Buddhist images have been reguarded as masterpieces of Buddhist art and Shilla culture of Unified Shilla in the eightth century. The Buddhist images are represented very dear, elegance and beauty of detail skill

The result can be summarized as follows. First, the following periodically changing characteristics were examined:roof form(gambrel/hipped-flat-gable), structure of roof and wall(wood-framed-cement masonry-RC-Light iron framed), roof material(thatched-tiled-slate-cement/steel sheet-asphalt/sandwich panel/mortar water-proofing), wall material(clay plaster/lime plastered-dressing tile/bricks-painting on the cement plastering-native stone dressing/siding/tile), fence material(masonry of stone and cement bricks), and courtyard materials(clay and concrete). Secondly, the regionally changing characteristics of those elements, rural housing structure, roof form, roof structure material, wall finishing material, fence and courtyard material in the outer space, differed according to the location of rural housing, i.e.north, middle, south region. The changing characteristics of both the roof structure and wall structure are similar to those of the three regions.

About 17% of historical properties in Korea were made of stones and most of them are exposed to weathering, as such that discoloring, cracking, and shattering occur from physical, chemical, mechanical, and biological effects due to outdoor placement. Proper treatments for conservation are necessary to prevent the weathering damage and to retain the original shape of stones. MMA, an acrylic monomer having low viscosity can be impregnated deep inside stones by consecutive compression and decompression process in a pressurized vessel. After the polymerization of MMA impregnate, the space inside of the stone was filled with PMMA. It is expected that water repellent and weather resistant properties will be improved because of the improved bonding of constituent materials in stones. In this study, moisture absorption, chemical resistance, and mechanical property of two domestic granites were examined after treating them with MMA for the purpose of determining the conservation value of this method that was possibly useful to the conservation of stone cultural assets.

In order to provide a scientific foundation for herb application in landscape, the photographs were taken from the herb landscape in urban green space and sightseeing garden. The questionnaire-based survey was also applied to analyze the cognitive situation of herb. Most investigators love herb, but have a low level of herb; Interviewees' consideration of herb function lie in ornamental, healthcare and medical treatment; The bulk of the visitors think herb landscape is insufficient; Investigators' preferences for herb application forms are landscape edging and combining with stone. We also probe into the optimum allocation form combining herb with landscape elements. When we combine herb with landscape water or landscape architecture, artistic conception and reasonable plant allocation should be considered; When we combine herb with landscape path or garden ornament, reasonable plant disposition and appearance and practical collocation should be thought over; When we combine herb with flower-border, richly colored landscape and reasonable plant allocation should be deliberated on.

We study tidal disruption and subsequent mass fallback process for stars approaching supermassive black holes on bound orbits, by performing three dimensional Smoothed Particle Hydrodynamics simulations with a pseudo-Newtonian potential. We find that the mass fallback rate decays with the expected -5/3 power of time for parabolic orbits, albeit with a slight deviation due to the self-gravity of the stellar debris. For eccentric orbits, however, there is a critical value of the orbital eccentricity, significantly below which all of the stellar debris is bound to the supermassive black hole. All the mass therefore falls back to the supermassive black hole in a much shorter time than in the standard, parabolic case. The resultant mass fallback rate considerably exceeds the Eddington accretion rate and substantially differs from the -5/3 power of time. We also show that general relativistic precession is crucial for accretion disk formation via circularization of stellar debris from stars on moderately eccentric orbits.

Stone introduced extremally disconnected spaces as the image of complete Boolean algebras under his famous duality between Bool and ZComp and they turn out to be projective objects in various categories of Hausdorff spaces and completely regular ones are exactly those X with Dedekind complete C(X, ). In the pointfree setting, extremally disconnected frame (= De Morgan frame) are those with De Morgan condition. In this paper, we investigate a historical aspect of De Morgan frame together with that of De Morgan.

In this paper, an improved method of hand detecting and hand gesture recognition is proposed, it can be applied in different illumination condition and complex background. We use Adaptive Skin Threshold (AST) to detect the areas of hand. Then the result of hand detection is used to hand recognition through the improved HMM algorithm. At last, we design a simple program using the result of hand recognition for recognizing "stone, scissors, cloth" these three kinds of hand gesture. Experimental results had proved that the hand and gesture can be detected and recognized with high average recognition rate (92.41%) and better than some other methods such as syntactical analysis, neural based approach by using our approach.
