The object of this study was to analyze the speciality of Korean traditional waterscape and unique landscape formed with reflection of the phases of the time sat the area of Juhabru(宙合樓) in Changdeok Palace as a basic research to find the prototype of Taeaek pond at Changdeok Palace and restoration of the palace. Originally, Taeaek pond at Changdeok Palace was constructed in KingInjo(仁祖) period as a name of Yongji(龍池), later it called Taeaek pond after King Sukjong(肅宗). There is an island as a symbol of the immortal isle, and Chungseojeong(淸署亭), Taiksujae(澤水齋) and Buyongjeong(芙蓉亭) which were built to view the waterscape in Taeaek pond. Buildings were built asymmetrical balance around Taeaek pond because of the morphological character of tetragonal pond. Arrangement of this area has a definite form of axial structure. Yeolgokwan(閱古觀) Gaeyuwa(皆有窩), pavilions, bridges, islands, Osumoon(魚水門) and Juhabru are located on the north and south axis, and island and Osumoon play a role as a intersection and form an east of west axis. In this study, manual of construction for an island and pavilions is provided by analyzing transformational process of island and pavilions at Taeaek pond. Furthermore, kings and officials used to statically enjoy the view around Taeaek pond area, but dynamic fishing and boating activity happened in King Jungjo(正祖) period. These historical backgrounds have an influence on the spatial organization of Taeaek pond. For instance, bridge between Taeaek pond and island was destroyed with the increase of the importance of boating. Symbolic structure around Taeaek pond means 'fish changes to dragon' and 'both of king and officials become one'. Taiksujai, carving fish, Osumoon and Juhabru are provided as a related spatial factors.

This study is an integral exploration of Feng Shui associated with the area around the birthplace of Kang Jeungsan, a sacred site of Daesoon Jinrihoe which holds that the Supreme God descended in human form at that location (through Kang Jeungsan). Through an on-site Feng Shui survey, the main focus of the research method was to explore the Feng Shui configurations around Kang Jeungsan's birthplace especially as it pertains to the connections among geomagnetic veins which lead to the Mount Shiru area. As a method of investigation, this study explored the Feng Shui of Gaekmang-ri Village and the geomantic veins leading up to Mount Shiru. This involved examining the landforms, topography, water flow, and geomantic veins of the area to reveal the overall Feng Shui configurations. Throughout the course of that on-site survey, this study first examined Mount Duseung and Mount Bangjang, also known as Mount Yeongju (sometimes collectively known as Mount Samshin), Mount Dongjuk, Mount Mangje-bong, Mount Maebong, and Mount Shiru. Then, this study stated some of the underlying issues through a scholarly approach based on various theories such as traditional geographical texts and theories on mountain-growth and water-flow from the perspective of Feng Shui. In particular, attention was paid to theoretical aspects of the uninterrupted and undulating flow of the terrain leading to Shiru Mountain. As a result, from a Feng Shui point of view, the connected network geomantic veins in the area of Kang Jeungsan's birthplace and the feng shui features and conditions were all examined through an on-site survey. The survey results revealed that the area forms a large Feng Shui site due to the vast interconnectivity among all the mountains that extend from the Honam vein and form organic relationships with one another. This even includes Mount Samshin in Honam. Considering the geographical conditions that formed a site that enabled harmony between divine beings and humankind, the surrounding place names also provide allusions to the understanding of the birth of Kang Jeungsan as the descent of Supreme God into the human world through the historical figure, Kang Jeungsan. This area is an ideal spot with a propitious spatial arrangement in terms of its Feng Shui. Feng Shui analysis reveals the site to be a place that holds an earth energy-hub transmitting a great energy of nature that cannot be measured by human power alone.

The virgin forests on and around Sungin-bong in Ulreung-do, an island situated between the Korean peninsula and Japanese archipelago, were investigated phytosociologically. They were classified into two communities, i.e. Fagus crenata var. multinervis - Majanthemum dilatatum community and F. crenata var. multinervis - Sasa kuriensis community. The former was subdivided into several units ; Acer takesimense - Allium victorialis var. platyphyllum group, including Tsuga sieboldii - Taxus cuspidata var. tatifolia subgroup and a typical subgroup, and Acer mono var. savatieri - Rumohra standishii group, including Dystaenia takeshimana subgroup and a typical subgroup. The other was subdivided into two subunits ; Acer okamotoanum group and a typical group. It was estimated that this area was orginally covered with beech and maple dominated forest vegetation and with Machilus dominated forest or bamboo forest. However, in these days, The natural vegetation of it has been destroyed and in future, may also be disturbed gradually by human activities. Judging from the coincidence method, the structure and distribution of the forest communities was more related to altitude than to topography. The phytomass, based upon the basal area of each community to $100m^2$ showed that Acer mono var. savatieri - Rumohra standishii group ($BA=7574.1cm^2$, $P=9,882,058cm^3$) haved the largest value and Tsuga sieboldii - Taxus cuspidata var. latifolia subgroup($BA=2126.3cm^2$, $P=1,746,755cm^3$) showed the smallest value. The flora of the vascular plants collected from this area consists of 71 families, 187 genera, 243 species, 1 subspecies, 44 varieties, 6 forms and 294 taxa in total.

For a few people's leisure, the natural environment have being deteriorated ceaseless. The plan of the Chungchongpuk Province and the Yungdong District in Chungchongpuk-do which drive foreword the sport and leasure complex designed to construct ski slopes, golf course, and resort hotel in 6,000,000 $m^2$ of natural ecosystem around the Mulhan Valley at Mulhan-ri Sangchon-myon Yungdong-kun Chung-chcngbuk-do by Dongsin Leisure have concerned decrease on biological diversity serious. This study carried out by census Amphibia and Reptilia fauna in the Mulhan Valley to expect the impact of animal diversity by construction of leasure complex and to call attention to understand that impact. 8 species in 5 Families of 2 Orders in Amphibia and 5 species in 2 Families of 1 Order in Reptilia were observed in the Mulhan Valley during June 24, 1994 to June 25, 1994 which showed to be similar to the Natural Park in Korea. 4 of 8 species in Amphibia(Hynobius leechii, Onychodactylus fischeri, Bufo bufo gargarizans, and Rana dybowskii) and 3 of 5 species in Reptilia(Eluphe rufodorsata, Dinodon rufodonatum rufodonatum, and Agkistrodon saxatilus) were revealed the Special Wild Animal recorded by the Ministry of Environment in 1993. Therefore, the Minjujisan seems to have highly reason to conservation by these animal diversity. Around the Minjujisan province was significant connecting the Taebaek Mountains and the Sobaek Mountains on biogeographically with Dokyusan National Park. The plan of Leasure complex in the Mulhan Valley should be cancel in consideration of destruction around the Dokyusan National Park severely by the Muju Resort, Ski slopes, etc. The Minjujisan must be conserve to the Zone of Natural Environment on Amphibia and Reptilia diversity and animal migration route.

물체의 3차원적인 정보를 복원하는 일은 그 정보의 일련된 이용에 있어서 중요한 문제이다. 이를 위해 여러가지 방법들이 연구되고 있으며, 그 중 shape from focus(SFF) 방법은 영상의 초점이 맞는 렌즈의 위치를 찾아내어 렌즈 공식에 의해 초점이 맞는 부분의 거리 정보를 구할 수 있다. 기존의 이 방법은 초점이 맞았는지의 정도를 계산하기 위한 focus measure 값들을 카메라의 광학축에 수직인 단순한 평면으로 가정하여 그 합이 최대가 되는 위치를 찾아내었다. 이를 개선하기 위해서 focused image surface(FIS) 개념이 연구되었고 그로 인해 더욱 나아진 결과를 얻었다. 물체의 FIS는 카메라 렌즈에 의해 초점이 맞게된 물체의 점들의 집합으로 이루어진 공간상의 면이다. 기하광학에 의해 물체의 모양과 FIS 상이에는 일대일 대응 관계가 있고 FIS의 형태를 구하는것이 결국은 물체의 모양을 복원하는것이다. FIS 개념을 처음 적용할 때는 물체의 모양이 부분적으로 영상 탐지기(image detector)와 같은 평면으로 가정하여 3차원 공간상에서 가능한 모든 방향의 평면에 대한 focus measure를 구하여 그 값이 최대가 되는 렌즈의 위치를 구하였다. 그러나 이러한 방법은 focus measure의 합이 정사각형의 윈도우에서 계산되기 때문에 곡면으로 이루어진 실제 물체에서는 오차르 ㄹ가지게 된다. 본 논문에서는 이와는 달이 평면이 아닌 곡면에 대한 focus measure의 합이 최대가 되는 렌즈의 위치를 구하여 이전의 방법들 보다 정확한 복원이 가능함을 보인다.

The Paekrogdam summit crater area, Mt. Halla, Jeju Island, Korea, composed of Paekrogdam trachyte, Paekrogdam trachybasalt, and Manseidongsan conglomerate in ascending order. Joint systems show concentric and radial patterns around the summit crate wall. The Paekrogdam crater is a summit crater lake which erupted the tuffs, scorias and lava flows of Paekrogdam trachybasalt after the emplaceent of Paekrogdam trachyte dome. SiO$_2$ contents of mafic and felsic lavas are respectively, 48.0∼53.7 wt.％ and 60.7∼67.4 wt.%, reflecting bimodal volcanism. And lavas with SiO$_2$ between 53.7 wt.% and 60.7 wt.％ are not found. According to TAS diagram and K$_2$O-Na$_2$O diagram, the volcanic rocks belong to the normal alkaline rock series of alkali basalt-trachybasalt-basaltic trachyandesite and trachyte association. Oxide vs. MgO diagrams represent that the mafic lavas fractionated with crystallization of olivine, clinopyroxene, magnetite and ilmenite and felsic trachyte of plagioclase and apatite. The characteristics of trace elements and REEs shows that primary magma for the trachybasalt magma would have been derived from partial melting of garnet peridotite mantle. In the discrimination diagrams, the volcanic rocks are plotted at the region of within plate basalt (WPB).
