This study was carried out to understand the immigration period, climatic conditions for mass immigration and bionomical characters ofthe brown pLanthopper(BPH) in Hae NamThe results are as follows ; (1) The Periods of first immigraion and mass immigration of BPH , were from the late June to early JuLy and from earlyto mid JuLy in HaeNam, that were faster about 15-30days than in inland of ChonnanThe climatic factors that related closely to mass immigration wereas follows ; temp.: $20{\;}~{\;}25^{\circ}C$, humidity : 86 ~ 95 % , wind direcion : SW, wind velocity: 1.0 ~ 2.9gm/sec. (2)The population of immigranted BPH was in the field much more overthe mountain near coast than other places . Biotype composition showed that biotype I was on the decrease and biotype II, III were on the increase (3)The bionomical characters were variable, for climatic conditions,that egg stage, nymphal stage and adult stafe of immigranted BPHwere 9-12days, 13-16days and 12-36days respectively, that hatchability(%) and emergence rate ( % ) were higher than 80%. The adult Longevity in female and macropterous BPH showed Longerthan that of male and brachypterous respectively. (4) The distance of nymphs and brachypterous adults move by walking was within 16cm over the water surface, by hopping was within 20cm horizontally.

We investigate the spatial distribution of highly conductive layer using the one-dimensional inversions of the new magnetotelluric (MT) measurements obtained at the mid-mountain (400 ~ 900 m in elevation) western area of Jeju Island and the previous MT data over Jeju Island, Korea. The conductive layer indicates the sedimentary layer comprised of Seoguipo Fomation and U Formation. There is a definite positive correlation between the top of conductive layer and the earth surface in elevation. On the contrary, the bottom of conductive layer has a negative correlation with the surface elevation. In other words, the conductive layer has a shape of convex lens, which is thickest in the central part. The basement beneath the conductive layer could be concave in the central part of Jeju Island. A kriging considering the correlation between the layer boundary and the surface elevation provides a reliable geoelectric structure model of Jeju Island. However, further studies, i.e. three-dimensional modeling and interpretation integrated with other geophysical or logging data, are required to reveal the possible presence of three-dimensional conductive body near the subsurface vent of Mt. Halla and the causes of the bias in the depths of layer estimated from MT and core log data.

Cheongpyeongsa Temple was originally built in the early years of Goryeo Dynasty, but its current structural framework was made by the Lord Jinrakgong Lee Ja Hyeon(1061-1125) of the middle Goryeo period based on the Zen thought after he began living in the Cheongpyeong mountain around the temple in 1089. The purpose of this study is to conceptualize, based on old documents, historical changes of the appearance and survival of man-made structures with in the Zen garden formed and developed after Lee Ja Hyeon laid the foundation for Munsuwon Zen garden. Among the eight, outside-the-temple hermitages built at the time of Lee Ja Hyeon's Munsuwon Zen garden, only three hermitages, which are Sik-am, Gyeonseong-am, Yangshin-am had been remaining thanks to restoration and repair until late Joseon Dynasty and preserved as symbolic hermitages. Also, the Yeongji Pond built at the time of Lee Ja Hyeon still remains as precious landscape relics which is meaningful as a genuine Goryeo-period pond. The nine pine trees said to be planted by Lee Ja Hyeon remained until middle 1800s through their descendant trees. When the Buddhist monk Bowoo Daesa(1509-1565)changed the name to Cheongpyeongsa Temple in middle Joseon based on the Munsuwon Zen garden built by Lee Ja Hyeon and greatly expanded it, he newly built and expanded all buildings inside the temple except for Neunginjeon(main temple building), resulting in the present temple structure. In addition, by greatly enhancing the level of scenery by reconstructing Yeongji Pond outside the temple area and transplanting garden plants from the royal court, he made Cheongpyeongsa Temple the most prosperous Zen garden in its history. But after the mid-1800s, which is late Joseon period, Cheongpyeongsa Temple failed to thrive further and began to decline, and so currently most buildings of the Zen garden have disappeared except for some parts of the temple and other facilities are neglected.

The purpose of this study was to examine the spatial and visual arrangement characteristics of Imsil Yi Ung-jae's old house's spatial and visual aspects in order to discover the value of landscape and traditional house garden. The results of this study are as follows. Dongchon-village in Dundeok-ri, where old house is located, is a typical form of with "Back to the mountain and facing the water(背山臨水)", and is located in the north of the three streams of water, forming a Jeonchaghugwan(前窄後寬). Dongchon Village, which has a traditional scenic spot between Danguidae(丹丘臺) and Samgyeseokmun(三溪石門), is understood to be the main street of Nojeokbong Peak and Gyegwanbong Peak, which is Ansan(案山), where the "A centipede flying in the sky(飛天蜈蚣形)". Yi Ung-jae's old house is the oldest existing high-priced house in the North Jeolla region and the closing price of a royal family of the Joseon Dynasty, which was arranged by Chunseongjeong(春城正), Yi Dam-son(李聃孫) in the mid-16C. The Japanese Invasion of Korea in 1592 and Japanese colonial era, the loyalty of the gate quarters, the filial piety of the gate quarters, and the faithfulness of the tablet(扁額) and Juryeons(柱聯) are enough to contribute to the rise of the value of a physical house. The men's quarters(Sarangchae), which are placed on a high-pocket or a layout without going against the sloping terrain, have the effect of making the distance as far as possible, enhancing its dignity and hierarchy as a royal building. In addition, the entrance to the main quarters(Anchae) through the four pillar gates(四柱門), the extensive support and the appropriation of the Chaewon(vegetable garden), and the official base for the Anchae are very unique compared to the general nobility. However, in the context of the postwar relationship, the shrine seeks to realize Confucian ideals while harmonizing with nature by arranging wide sponsorships around it. On the other hand, it is confirmed that there was a pond in the form of a circle in a square(方池圓島型) with a relatively large area, which is now disturbed and damaged. Written by the high priced planting species are sponsored pine trees, hackberry, persimmon trees, Japanese apricot flower, Ohmomiji, and plum tree in the side garden, as well as cotyledon trees in the outside garden. However, although flower bed(花階), which is built on the stone axis, is a place that clearly shows the expensive garden, it seems to have lost the texture of the plant due to the extremely high variety of species and the splendor that does not match the plant landscape of the flower world. Yi Ung-jae's old house is highly valuable as it is a portrait house of a prince of the blood in the mid-Joseon Dynasty. Based on these findings, this study proposed a plan to improve the management of high prices that could be met.

The conclusion of this research after analyzing and interpreting the landscape structure and meaning of Yeongsajeongpalkyung (永思亭八景) that appears in Yeongsajeongpalyeongsi(永思亭八詠詩) of Cheonggye(靑溪) Yang, Dae-bak(梁大樸, 1544~1592) and through document studies, poetry and painting analysis and interpretation, and site investigation, is as follows. Yeongsajeong and its nearby lands are the area of "Yeongsa", where the builder, Ahn, Jeon(安?, 1518~1571) worshipped towards the grave of ancestors, and Yeongsajeongpalkyung oversees a family burial ground in Namwon, centering around Yeongsajeong such as Yocheon, Geumseokgyo and Cheonggyedong, and Sunjagang River and Mountain Jiri, which are the foot hold and key points of advantageous scenic views in Namwon. Yeongsajeongpalkyung, unlike general Jeongjapalkyung, shows a panoramic bird's-eye structure overseeing the landscape and scenery of the Yocheon area and Sunjagang River, in addition to Yeongsajeong, while show in a transition of location, a multi-view structure and time. The trace of visual unity with Sosangpalkyung of China can be seen in many places in Yeongsajeongpalkyung, which seems to be a transitional feature of composing poems regarding Palgyeong during the mid-Joseon dynasty, which pursues harmony with the local landscape of the Namwon area. The 'Changsongchwijuk(蒼松翠竹)' appearing in each of the first and second scenic views of Palgyeong and Yeongsajeongpalyeong can be understood as an incarnation of Yang, Dae-bak, the author of Palyeongsi or Ahn, Jeon, the builder of Yeongsajeong. On the other hand, as a result of interpreting the yin-yang features of poetic diction and picture elements appearing in the subtitle of Yeongsajeongpalyeong, Palyeongsi seems mostly full of yin-like elements and Palgyeongdo. Moreover, as a result of comparing and analyzing the acts expressed in and acts described in Yeongsajeongpalyeong, based on the fact that the reis almost no common ground between the two media except for Soongangmowoo, the third scenic view, the formal similarity between the two media can be acknowledged, however, it is difficult to discover any substantive 'integrity of poetry and painting'.

Forest resources utilization and variable disturbance history have been affected the rarity and conservation value of forest relict trees, which served as habitat for forest biodiversity, important carbon stock and cultural role include human and natural history in South Korea. This study was conducted to establish the baseline data for forest resources conservation by clarifying species diversity, spatial distribution and ecological characteristics (individual and habitat) of forest relict trees (DBH > 300 cm) based on the data getting from mountain trail, high resolution aerial photos and field professionals and field survey. As results, 54 taxa (18 family 32 genus 48 species 1 subspecies 3 variety and 2 form) as about 22% of tree species in Korea was identified in the field. 837 individuals of forest relict trees were observed and the majority of the trees was in Pinaceae, deciduous Fagaceae and Rosaceae, which families are abundant in population diversity. High elevation area was important to relict trees as mean altitudinal distribution was 1,200 m a.s.l as likely affected by human activity gradients and mid-steep slope and North aspect was important environment for the trees remain. Many individuals exhibited 'damage larger branch' (55.6%) and consequent relatively lower mean canopy coverages (below 80%). Synthetically, present diversity and abundance of relict forest trees in South Korea were the result of complex process among climate variation, local weather and biological factors and the trees of big and old were estimated to important forest biodiversity elements. In the future, clarifying the role and function of relict trees in forest ecosystem, in- and ex- situ programmes for important trees and habitat, and activities for building the background of conservation policy such as "Guideline for identifying and measurement of forest relict trees".

This study infers the origin and production period of the , which is in the Onyang folk museum, through analysis and interpretation of the Haeju Palgyeong and exploration of the landscapes and traditions contained in the painting. The first collection of landscapes to Haeju was identified as Haeju Palgyeong by Ku Sa-meng (1531-1604). Yoo Man-ju, writing in 1782, referred to it as Go-palgyeong in 『Heumyeong』 while Haeju Palgyeong was defined as Geum-palgyeong (今八景), which is the Haeju Palgyeong in the earliest period confirmed by literature. is 'Boating on the Nam river (南江泛舟)', 'Lotus viewing at Buyongdang (芙蓉賞蓮)', 'Foot washing at Gwangseokcheon (廣石濯足)', 'Seokbyul at Haeunkyo (泣川送客)', 'Fishing at Haeunjeong (東亭釣魚)' and 'Sea view at Namsan( 南山望海)', and the final two contain a picture that contains 'Viewing the moon at Yeonghaeru (瀛海玩月)' and 'Writing contest and Archery at Baeklimjeong (栢林觀德)' The Suyang Chaemi(首陽採薇), Shingwang-jeoljeol (神光霽雪), and Jiseong falls (池城瀑布) of Gopalgyeong, which were excluded from Haeju Palgyeong, are all landscapes unfolding as a grand site of Suyangsan Mountain. is a result of the reorganization of Seunggyeong centered on Eupchi (邑治), away from the Suyangsan area. It has emerged as a seunggyeong of Haeju. The elaborateness of trying to contain the detailed prizes representing Haeju, such as the specialty sake of Haeju, is revealed. Most of the landscapes depicted in are historic and outstanding spots in Haemok, but the scenes of life related to daily life are properly arranged. In addition, Foot washing (濯足), Fishing(釣魚), Doing laundry (漂母), Lotus viewing (賞蓮), Sending guests (送客), Drinking (飮酒), sea viewing (望海), Moon viewing (玩月), Archery (射藝), Poetry (詩作), Drinking tea (飮茶), and Dancing (歌舞) are of various styles. Compared with the Gopalgyeongs, Haeju Palgyeong did not take into account the distribution of landscapes in the four seasons, and the small-sized view was also broken. When considering the time of the construction of Haeunjeong and the deterioration of Yeonghhoeru, it is believed that was produced in the early- to mid-18th century. is considered to be a painting that contributed to strengthening the sense of intimacy with the local people and promoting the pride of Haeju by showing the representative scenery of Haeju, such as scenic spots and customs, away from the ideal utopia.

Ssangsanjae was created in the mid-1800s, It is located at Jiri Mountain to the north and the Seomjin River to the south. This garden has not changed much even though it has passed through the sixth generation since its creation, so it still retains the features of a private garden in the late Joseon Dynasty. This study focused on the changing landscape of Ssangsanjae as a historical garden; through field surveys, interviews and analysis of builder's collection, boards and couplets. Ssangsanjae is largely classified into inner and outer gardens, and the inner is divided into an entry space, a residential space, and a backyard. The backyard consists of Seodangchae, it's garden, Gyeongamdang, and swimming pool, and is connected to the Sado Reservoir area, which is the outer garden. The distinct vegetation landscape of Ssangsanjae are a 13,000m² bamboo and green tea field, Peony(Paeonia suffruticosa Andr. and Paeonia lactiflora var. trichocarpa(Bunge) Stern) planted on both sides of the road that crosses the lawn, the view through a frame(額景) shown by the twisted branches of Camellia and Evergreen spindletree, and a fence made of Trifolia Orange(Poncirus trifoliata) and Bamboo. Ssangsanjae stands out for its spatial composition and arrangement in consideration of the topography and native vegetation. The main building was named by the descendants based on the predecessor's Aho(pseudonym), and it is the philosophical view of the predecessors who tried to cultivate the younger students without going up on the road. The standing stone and white boundary stone built by Mr. Oh Ju Seok are Ssangsanjae's unique gardening facilities. The stone chairs, and swimming pool which were created by the current owner for the convenience of families and visitors also make a distinctive landscape. Ssangsanjae, for residents, was a place for living, exchanging friendships, training himself and seculusion, for children was a place for learning, but now is 'the private garden' where many people can heal themselves. Over the 200 years, the landscape of Ssangsanjae's inner and outer gardens experienced large and small changes. As such, it is necessary to recognize the historical gardens with changing properties as a living heritage. This study is significant in that, as the first study to approach Ssangsanjae in the view of landscape research, it provides basic data on Ssangsanjae as a destination of garden tourism.
