The Samrangjin Caldera, a trapdoor-type, formed by the voluminous eruption of the silicic ash-flows of the Samrangjin Tuff which is above 630m thick at the northern inside of the caldera and thinnerly 80m at the southern inside. The caldera volcanism eviscerated the magma chamber by a series of explosive eruptions during which silicic magma was ejected to form the Samrangjin Tuff. The explosive eruptions began with phreatoplinian eruption, progressed through small plinian eruption and transmitted with ash-flow eruption. During the ash-flow eruption, contemporaneous collapse of the roof of the chamber resulted in the formation of the Samrangjin caldera, a subcircular depression subsiding above 550m deep. During postcaldera volcanism after the collapse, flow-banded rhyolite was emplaced as cental plug along the central vent and ring dikes along the caldera margins. Subsequently rhyodacite porphyry and dacite porphyry were emplaced along the inner side of the ring dike. After their emplacement, residual magma was emplaced as a hornblende biotite granite stock into the southwestern caldera margin. In the northeastern part, the eastern dikes were cut final intrusions of granodioritic to granitic composition along the fault zone of $^{\circ}$W trend.

It has been studied that aminoacetonitrile was associated with the inhibition of collagen fiber, argyrophilic fiber and oxytalan fiber synthesis. This experiment was performed, by the basic knowledge of above mentioned study, to study on the biological effect of aminoacetonitrile to the developing periodontal ligament in Sprague Dawley rat. twenty two of female rats weighing about 200gm were gestated. In 7 days after gestation, the experimental rats were injected aminoacetonitrile 7 times intraperitoneally. After parturition, delivered fJtuses were divided into 4 groups and each group was sacrificed to 1 day, 7 days, 14 days, and 21 days after delivery, schematically. All the fetuses were observed on their periodontal ligament by histological and histo chemical methods. To study on the components of periodontal ligament fiber in these experimental study van Gieson, Masson's trichrom, argyrophilic fiber, oxytalan fiber, methyl green pyronin and periodic acid-Shiff staining were performed. Results were as follows; 1) Retardation of functional orientation in periodontal ligament collagen fiber was observed in 1 day fetuses hut this appearance was diminished gradually and recovered in normal condition in 7 days fetuses. 2) Distribution of argyrophilic fiber in 1 day fetuses was oriented delicately and loosely but volume of this fiber was gradually thickened and distributed densely. 3) Oxytalan fiber was oriented dendritic ally and contradictorily in 14 days fetuses but their orientation was changed into oblique form in middle portion of roof and their numbers were increased gradually. 4) Pyronin-philic stain of fibroblast was gradually deepened in 7 days fetuses and this finding also suggested to the depreciation of collagen synthesis in this specimen. 5) PAS positive line was observed continuousely at the portion of cervical to the middle root surface.

The Sydney Opera House is built on a peninsula of rock that juts out into Sydney Harbor. The site was once a landing place for ships. Utzon, Architect, designed the theatres for the Opera House to fit the shape. The two theatres were placed side by side so that they both had extensive harbor views. The Sydney Opera House is designed the foyers to take full advantage of these sights. Because the building would be seen from all sides, even from above, it was to be a piece of sculpture. The outside was as important as the inside. The audience enters from behind the stage and walks around to the foyers overlooking the harbour. The wing and backstage areas are small because of the way the foyers wrap around the theatre. The stage is made up of large platform lifts which provide the vertical movement for changing scenery. The sets come up from the workshops below stage. The flytower fits under the largest roof shell and doesn't break the skyline. The important elements are the podium, the shells and the reminders. The podium, the huge monolithic concrete structure, contains hundreds of rooms and nearly all the technical equipment. The podium is clad with pink granite slabs and seen from the water. This design eliminated a maze of fire escape stairs and, at the same time, gave people a wonderful view of the harbour. The egg shell is remarkably strong and express the form as the symbol of the site.

The purpose of this study is to investigate the basic historical characteristics and its modern trend of Torajan traditional housing architecture in Sulawesi Province, Indonesia. The Toraja culture belongs to the cosmological culture with Cosmos centric characteristics. A traditional house, being called 'tongkonan' in Toraja region, is more than just a structure, representing the symbol of family identity and tradition. The Torajan architecture is a combination of the myth and cosmos, also regional conditions. With a short description of the general conditions and spiritual values of the Toraja, this paper explains the space-composition, the stylistic characteristics, the ornamental elements, construction, and its modern trend, etc. In general, it is raised on stilts several metres high, with a dramatically boat-shaped roof. Village layout varies according to size. The houses are arranged in a row, side by side, with their front gables facing north. Each house stands opposite its own rice-barn. The houses with their oblong ground-plans, built on piles set on stones. The interior is divided into three or four rooms, having few window. The houses are embellished with carving and paintings, and the facades display engraved and painted geometric and figural designs. The most frequent motif is the buffalo head, ranging from the realistic to the highly stylized. The Torajan traditional housing have experienced radical changes during the Modern period. In spite of the popularity of new modern house-styles, the traditional architectural style is often now constructed as an icon of Toraja identity. This paper will be helpful for understanding regional diversity of the traditional housing in Southeast Asia.

We propose a new building detection and description algorithm for Lidar data and photogrammetric imagery using color segmentation, line segments matching, perceptual grouping. Our algorithm consists of two steps. In the first step, from the initial building regions extracted from Lidar data and the color segmentation results from the photogrammetric imagery, we extract coarse building boundaries based on the Lidar results with split and merge technique from aerial imagery. In the secondstep, we extract precise building boundaries based on coarse building boundaries and edges from aerial imagery using line segments matching and perceptual grouping. The contribution of this algorithm is that color information in photogrammetric imagery is used to complement collapsed building boundaries obtained by Lidar. Moreover, linearity of the edges and construction of closed roof form are used to reflect the characteristic of man-made object. Experimental results on multisensor data demonstrate that the proposed algorithm produces more accurate and reliable results than Lidar sensor.

In the city of Asia like Seoul and Tokyo, aggregate power is poured into the city making which is suitable in new age. Large-scale re-development is active in various places as the present condition, As for the various East Asian cities, high-level utilization conversion of the land and high conversion of the building are advanced. As for these realities, the re-development is advanced in the situation that has not been clarified enough though it is true that green of the city has decreased. This research was aimed at the clarifying the allocation of greenery when proceeding with town planning projects by quantifying the possibility of allocating greenery in the form of rooftop landscaping in redeveloped areas. Moreover, the distribution of the green in the re-development region was calculated and the coexistence level of green space was calculated, The realities of a desirable green were clarified in the spectacle by understanding a sight and spatial continuousness in the green. In order to clarify the potentiality of roof greenery revaluating, the research was conducted by analyzing from aerial photographs, in Tokyo and Seoul, And the flow of the research was conducted by selection of research object area, taking pictures, acquisition of the aerial photography, rearrangement the data and the analysis. As a result, I was able to prepare a land vegetation coverage classification chart and obtain data pertaining to the level of urban and green tract of land for the researched cities of Tokyo and Seoul. By analyzing this data, we were able to indicate patterns of greenery unable to be obtained through data from ratio of vegetation coverage and ascertain the effectiveness of rooftop landscaping.

In the past, the rooftop was a place where a water tank was to be installed, and a space of secretion and concealment such as a warehouse exposed in the air. It was because it was judged to hinder the beauty of a city as a whole without having any functional value per se. However, the roof portion is increasingly being utilized for a space such as a cafe, a pub, and a lounge as the rooftop is highly recognized as a place for leisure activities other than an idle space in modern times. Nonetheless, there are no detailed ordinances and criteria corresponding to such circumstances. For example, in case of the rooftop space, the building code applied to the rooftop space is a legal system when the rooftop was an idle space in the past though people have now accessed more increasingly to the rooftop than in the past. This study investigated the definition on the rooftop space evolved in accordance with the change of the rooftop space and the related legal system in Korea, and conducted a survey for the purpose of performing the field investigation for the analysis of physical status in 117 spaces that form the rooftop space in the rooftop of small-scale commercial facilities with 2 stories through 4 stories in Korea and analyze the recognition of users and analyzing the recognition of users. We analyzed the problems in the rooftop space through analysis of derived data, and suggested improvement plans.
