The purpose of this study was to investigate the flora of Mt. Bongrae in Busan from February 2004 to May 2005. The flora in the surveyed area were identified 291 taxa that belonged to 82 families, 201 genera, 251 species, 35 varieties, and 5 forms. Among them, evergreen broad trees were identified 21 taxa, naturalized plants 30 taxa, especial plants decided by Ministry of Environment 24 taxa. By the vegetation of each slope, in northeast slope, it was dominated such as Pinus thunbergii community, Chamaecyparis obtusa community, Amorhpa fruticosa community, Trachelospermum asiaticum var. intermedium-Hedera rhombea community, north-northeast slope, it was distributed both Pinus thunbergii community and board-leaved tree community. In the southwest slope of coast site, it was presented plantation plants, according to altitude distributed such as natural vegetation, evergreen broad trees, warm-temperate plants. In southeast slope, it was to represent secondary vegetation such as Alnus firma community as a forest fire. Underside was mainly to search herbs such as naturalized plants and cruciferous family as a vegetable garden. In northwest slope, it was searched trees such as Pinus thunbergii community, Lindera obtusiloba, Styrax japonca, Prunus sargentii, Aralia elata, Zanthoxylum piperitum, Akebia quinata and herb layer such as Osmunda japonica, Allium thunbergii, Liriope platyphylla, Corydalis ochotensis, Scilla scilloides, Viola orientalis. Around the top, it was distributed such as Rhododendron mucronulatum-Rhododendron schlippenbachii community, Carpinus coreana, Viburnum erosum, Sorbus alnifolia.

Gangwon Provincial Office, which is Historical Landmark No. 439, existed from 1395 to 1895. It played a significant role of provincial administration. Gangwon Provincial Office was rebuilt in the $17^{th}$ Century when governors' additional job system began. It had 50 buildings and 670 sections. During the Japanese colonial era and the Korean War, most of the buildings were demolished, and in 2005 partially restored. Currently, after the old Wonju City Post Office was demolished, the back garden facilities of the Provincial Office are being restored. The back garden of Gangwon Provincial Office was completely destroyed when the Japanese army base at Wonju made it a playing field during the Japanese colonial era. After demolishing the old post office in the back garden, excavation and investigation were made. A pond and building relics were found, but they were too damaged to be restored. However, this thesis found that there were Bongraekak, Yeongjusa(Kwanpungkak), Cheyako, Joojeong Rainbow Bridge after studying literature and paintings. There were also Hwansunjeong and Bangjangdae outside the pond. The names of the back garden and how they were made are related to hsien. In the pond, they made 3 islands signifying Mt. Samshin(immortal world) in the legend and built pavilions on that. The pavilions of the back garden were named Bongrae, Yeongju, and Bangjang, and the titles of other pavilions also had the names of hsien. The back garden of Gangwon Provincial Office was made like an immortal world, befitting its role of governing Mt. Bongrae(Mt. Geumgang.) The governors of Gangwon Province often went to the back garden and enjoyed becoming a hsien. They regarded themselves as the owners of Bongrae, i.e., the immortal world. Gangwon Provincial Office has a unique historical significance because it implemented an immortal world, making use of the characteristic of Gangwon Province.

We have developed a wide-field imaging camera system, called WICZO, to monitor light of the night sky over extended period. Such monitoring is necessary for studying the morphology of interplanetary dust cloud and also the time and spatial variations of airglow emission. The system consists of an electric cooler a CCD camera with $60\%$ quantum efficiency at 500nm, and a fish-eye lens with $180^{\circ}$ field of view. Wide field imaging is highly desired in light of the night sky observations in general, because the zodiacal light and the airglow emission extend over the entire sky. This paper illustrates the design of WICZO, reports the result of its laboratory performance test, and presents the first night sky image, which was taken, under collaboration with Byulmaro Observatory, on top of Mt. Bongrae at Yongweol in January, 2004.
