This study was carried out to find out characteristics and contamination status of the urban-forest soils. Both topsoil (0-20 cm) and subsoil (40-60 cm) samples were collected from Namsan, Changdeok-palace, Seongjusan and Odaesan (control). The samples were analyzed for physicochemical properties, heavy metal (Cd, Cu, Pb, Zn) and anion $(NO_3\;^-,\;SO_4\;^{2-})$ contents. Soil pH of Odaesan was the highest followed by Namsan, Changdeok-palace and Seongjusan. The anion concentrations of the soil samples were in the order of Namsan, Seongjusan > Changdeok-palace > Odaesan. The relationships between soil pH and the anion concentrations showed highly significant negative correlation, which indicated acidification of soil due to air pollutants such as $NO_3\;^-$ and $SO_4\;^{2-}$ was going on. The heavy metal contents of the soils of urban-forest were higher than those of control. Heavy metal contents in the topsoil were higher than those in the subsoil. Since urban-forest soils were quite vulnerable to acidification and heavy metal accumulation due to chronic exposure to air pollutants such as automobile exhaust, a comprehensive countermeasure not to deteriorate urban-forest ecology must be prepared in the near future.

We have increasing number of new ponds planned and designed in traditional styles. However, many of the stoneworks at the edges of those new ponds are not the characteristics of our traditional ponds. This study is aiming at surveying and analysing the building techniques of Korean traditional water edges built with stones, by investigating selected ponds in royal palace gardens. This study was conducted through field investigation and literature reviews. Nine ponds from Gyongbok Palace, Changdeok Palace, and Changgyong Palace, which have many well-preserved ponds of various styles, were surveyed. First of all, the building materials (stones), or the kinds and sizes of stones used for the edges of ponds were surveyed. Secondly, construction methods, or the height and techniques of buildings stone walls were surveyed. Major findings were, first, the edges of most ponds constructed with granite Jangdaeseok, usually 120cm-140cm long, and 30cm-40cm thick. The only exceptions were those ponds which seemed to have been influenced by Japanese style. Second, typical pond ages were up-right vertical walls. Granite jangdaeseoks were piled-up 2 stories or up to six stories. Exceptions were Bandoji Pond and Chundangji Pond which had been constructed during latest period(King 'Ghojong' period). Third, heith of stone walls were between 60cm and 220cm. The depth of ponds were about 150cm or less, and the rest of the edge wall height was freeboard. Though the results of this study was not made by precise investigation and actual measurement, they could be fundamental information and data for the traditional styles of the Chosun dynasty Palace. It is believed that continuous researches on this matter will result in important and fundamental data of the establishment of traditional water edges.

Weoldae -which we can find inside Joseon palaces- is usually erected in front of important structures including the Main Hall(Jeongjeon, 正殿). There is no clear definition of its nature that we can find in official law codes or dynastic ritual manuals, and such records do not specify what kind of rules should be observed in creating them either. In illustrations of palaces such as and , Weoldae can be seen at structures such as the Main "Jeongjeon" Hall(正殿), Royal office(Pyeonjeon, 便殿), Royal Quarters(Jeongchim, 正寢), Queen's bedroom(Chimjeon, 寢殿), Quarters of the Crown Prince(Dong'gung, 東宮), and other structures. All these structures equipped with a Weoldae were related to special figures inside the royal family such as the king, the queen, the crown prince, and the crown-prince' son. These figures were literally above the law, and as such their treatment could not be defined by law. And these spaces were where they worked or rested while they lived, and where their posthumous tablets(Shinju, 神主) or portraits(Eojin, 御眞) were enshrined after they died. (When such spaces were used for latter purposes, they were designated either as 'Honjeon[魂殿, chamber of the tablet]' or 'Jinjeon[眞殿, hall of portrait']). Joseon was a Confucian dynasty with a strict social stratification system, and the palace structures reflected such atmosphere as well. We can see that structures described with Weoldae in and were structures which were more important than others that did not have a Weoldae. Among structures with Weoldae, the place which hosted most of the dynastic rituals was the Main Hall. In this Main Hall, the King swore an oath himself, passed the incense(香) himself during memorial services, and observed honoring ceremonies[Manbae-rye(望拜禮)] at the "Hwangdan"(皇壇) altar which was built to commemorate the three Ming Emperors. The so-called "Two Palaces[兩闕]" of Joseon shared a unique relationship in terms of their own Weoldae units and the rituals that were held there. In the early half of the Joseon dynasty period, Gyeongbok-gung(景福宮) and Dong'gweol(東闕) constituted the "Two palaces," but after the war with the Japanese in the 1590s during which the Gyeongbok-gung palace was incinerated, Dong'gweol and Seogweol(西闕) came to newly form the "Two palaces" instead. Meanwhile, Changdeok-gung(昌德宮) became the main palace[法宮], replacing the previous one which had been Gyeongbok-gung. In general, when a king moved to another palace, the ancestral tablets in the Honjeon chamber or the portrait in the Jinjeon hall would accompany him as well. Their presence would be established within the new palace. But king Yeongjo was an exception from that practice. Even after he moved to the Gyeong'hi-gung(慶熙宮) palace, he continued to pay visit to the Jinjeon Hall at Changdeok-gung. While he was positioned inside Gyeong'hi-gung, he did not manage the palace with Gyeonghi-gung as its sole center. He tried to manage other palaces like Changdeok-gung and Chang'gyeong-gung(昌慶宮) as well, and as organically as possible.

This study was carried out with a focus on the factor on the periodical space organization of Daebodan (大報壇: the altar of great recompense) in Changdeok Palace, which is significant in terms of political history in the late Chosun Dynasty, and consider the factors in the formation of the structural system through historical records and drawings. Daebodan has the ideology of righteousness to the Ming Dynasty which the hierarchy of the Joseon Dynasty. who felt the crisis of the domination order, imposed as a solution after the Manchu war of 1636. In addition, Daebodan was built by complex factors that entailed the self-esteem of the 'Joseon Centralism Ideology (朝鮮中華)' and the desire of the sacrificial rituals for Heaven that were imminent to the kings of Joseon. Superficially, Daebodan has the spatial organization of the Sajik (社稷) Altar and the placement of an annex building, but had the applied placement due to limited topography and access to the backyard. Furthermore, the lateral structure of Daebodan multiply accepted various factors of the nine step's stairs, the hight of five cheok (尺), the circumstance of two floors that were showed in the altar and platform with small fences and an imperial order including the internal form of Hwangjangbang (黃帳房). Moreover, the name of the alter came from 'the Jiaote Sheng Book of Rites(禮記 郊特牲)' representing 'the suburban sacrifice ritual for Heaven (郊天)', and it was built by not only combining the system of the Sajik Altar in the Joseon Dynasty and China but also avoiding 'excessive etiquette (僭禮).' The point is a remarkable feature shown by the structural system of Daebodan. Thus, it is considered that the 'Notion of Confucian-Cultural Succession (中華繼承意識)' and the desire of the sacrificial rituals for Heaven were expressed by the structure and form of altar. This study examined the process of the creation, expansion, decline and disposal of Daebodan in a chronological order, and found that the ruling ideology of the governing elite by the political and cultural background of the era at each transitional point was reflected in the spatial formation of the altar. On the other hand, as a result of performing a field survey to find the location in accordance with Daebodan in drawing materials, there remains items such as worked stones from Daebodan, precast pavers and fragments of proof tile discovered in the surrounding of tora vine (Actinidia arguta) which is a natural monument of Changdeok Palace. As such, verification through future excavation and investigation is required.

It is identified that an initial person who built of 'Seoul Gyedong Modernized Hanok(former Min Hyeong-gi house)' used as 'Bukchon Culture Center' in present, was not Min Hyeong-gi, but his wife, Yu Jin-gyeong, and she built it when 8 years went on after his death(1879~1973), and the construction year was at the gate of Chuseok in 1921. Yu Jin-gyeong was Head Family's Eldest Daughter-in-law in family of Yeo Heung-min who was an influential person at the late Joseon Dynasty and was widow who had only son for 3 generations. And she built this house and moved to gain daughter and live futher grandchilds together in law in new nest. It is arranged that an annex surrounds with main building as the central figure. And this house emulates Yeonkeong-dang in backyard of the Changdeok Palace for 'preservation of main building' and Chim-bang-ga-toe applied on a bedroom in a palace is applied around nobleman family's the main room. It is rare case and expresses that a palace factor is borrowed. Yu Jin-gyeong's house is that a tradition Hanok is adjusted closely in city and central and basing mode as 'protective bedding' and building concept as 'a noble and protective architecture' is realized. So it has a character that development of Hangrang architecture is appeared and Head Family's Eldest Daughter-in-law widow of modern upper class had a special benefit. As well as, a meaning that it is experimental house based on tradition and is build of Hanok with housekeeping as the central figure for appear a form which has minimal Hangrang for housekeeping in yangban family of modern city, can be found.

The influence of small urban parks(green ratio is 100%) on the temperature pattern over the urban and its surrounding area was examined by analyzing the case of in and around Changkyeong palace, Changdeok plalace and Jongmyo, Jongro-gu, Seoul. The pattern of temperature over urban parks and their surrounding built-up area was analyzed from September to November 2000, measuring maximum and minimum temperatures with fixed sensors(maximum and minimum thermometer)and real-time temperature depends largely on both the land-use type and the distance from the park border. In the case of maximum temperature, the lowest value appeared on the green area within parks and the highest value on the built-up area far from the green area. The maximum temperature difference between parks and built-up areas was up to $7.3^{\circ}C$. In the built-up area, the maximum temperature of commercial areas was higher than residential areas. In the night time, not only land-use type but also topography is important for the spatial distributlon of temperature because of the cold airflow from adjacet hills. The horizontal temperature profile by mobile measurement is also related to land-use type and to the distance from the park borders. There is a magnitude of $1^{\circ}C$ temperture difference over a distance of 200m and $3~4^{\circ}C$ over a distance of 400m from the park borders.

This study was carried out to find the prototype of the rear garden in Changdeok Palace during King Jungjo's reign through Gang Sehwang's "Record of Strolling with King in the Forbidden Garden", and the site of this study included the whole areas of Ongnyucheon(玉流川), Mansongjeong(萬松亭), Mangchunjeong(望春亭), Jondeokjeong(尊德亭), Pyemwoosa and Taichungmun(太淸門). The characteristics of the area of Ongnyucheon described in Record of Strolling with King in the Forbidden Garden was the shape of Wiyiam expressed three-dimensional mountain such as the fence surrounding Soyojeong(逍遙亭) and the painting techniques of Fu Pi' ts'un and pond in front of Taegeukjeong(太極亭). The pond in front of Taegeukjeong(which was described by Gang Sewhang) is also identified in Donggwoldo(東闕圖) and this study judged that the pond was removed during the maintenance process of Ongnyucheon, where was scheduled as the place of entertainment when Chinggyong-Yesik(稱慶禮式: Royal court rites) was held to celebrate the 40th anniversary of King Gojong's reign. The characteristics of the whole area of Mangchunjeong where was the attraction point for flower viewing in the forbidden garden was surrounded by the sculptured fence, and Mangchunjeong which was hexagonal structure was located in the inside of the structure on both sides of the main building. The cornerstone was carved with white jade. Also a corridor assumed as Chunhyanggak(天香閣) was adjacent to Mangchunjeong. Gang Sehwang confirmed the space organization appeared in Donggwoldo by describing the attached building of Pyemwoosa, Taichungmun, and surrounding fence in detail.

This study focused on the constructional concepts, landscape design techniques and changes made of the Sandan(山壇) area in the rear garden of Changdeokgung Palace based on the spatial organization of the zone. The results of this study are as below. Constructional layers that have been maintained throughout the centuries from King Injo(仁祖), King Sukjong(肅宗), King Sunjo(純祖), the Japanese colonial period to the present, were found in the Sandan area. The Sandan area, which was developed with the establishment of Chuiseungjeong(取勝亭) during the ruling of King Injo(仁祖), was created as a resting place for the King, and its usage continued until King Sukjong(肅宗) built Nakminjeong(樂民亭). However, the whole area was reorganized to host ritual ceremonies, where ancestral rites were performed for the mountain gods, after Sandan and Baekunsa(白雲社) were built during King Gojong's reign, before the drawing of 'Painting of Eastern Palaces(東闕圖).' The architectural component used then appears to have been designed to serve ancestral ritual formalities for the god of land, or to satisfy the religious desires of the royal family not fulfilled by Confucian courtesy. These are characteristics that define the Sandan area. Meanwhile, the analysis of the ground plan of the Changdeokgung Palace revealed that the Sandan had been maintained until the Japanese colonial era, but was removed sometime after liberation. The area underwent extensive reform in the early 1970s, when the whole area was developed into a tourist destination called Bingcheon(氷泉). Then, a new road that runs through Bingcheon was laid, and the present condition reflects the construction result of the time. An interview with a person who had taken part in the repair work in the 1970s confirmed that the construction work at the time had the goal of establishing two drainage systems for drinking water and copied the Okryuchon(玉流川) well.

State-designated rain gauge pedestals, including a rain gauge support, were installed in front of the "Imunwon" at Changdeok Palace, made from various rock types. Some of those pedestals provide exact information on their production dates. These rain gauge pedestals are highly valuable as scientific instruments; however, there has been insufficient scientific research carried out on them. Therefore, precise analysis and conservative consideration are required. As a result of petrographic character analysis, the Changdeokgung rain gauge pedestal has been classified as marble. Furthermore, comparison of the results of P-XRF analysis with GSJ reference samples (JLs-1, JDo-1) has determined it to be dolomitic marble. Applying the same analysis to other state-designated rain gauge pedestals, it was presumed that the rain gauge supports at Gyeongsand-do Provincial Office and Gwansanggam were each made from aplite, pinkish medium-to-coarse biotite granite. Results confirmed that only the Changdeokgung rain gauge pedestal was made from marble. Marble is viewed as having an identity specificity rooted in a certain historical background. According to the tendency towards stone figures being made from marble, especially dolomitic marble, it is necessary to further studies whether particular rocks were used to make royal stone figures in Joseon Dynasty.

In this work, scientific and systematic analysis was conducted for finding out the methods and techniques of ancient ink stick making. Analysis the ancient ink stick on ancient documents and wooden writing as letter or painting, we concluded as followings. From the analysis of ancient wood by dendrochronology, wood was cut at 1899, which provided the information on the year of ink stick's made on writing on ancient wood. Single particle size for soot of ancient ink stick was 107 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, compared to 38 to 86 nm on the letter on ancient 12 paper document. Aggregate particle size was 370 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, but 206 to 318 nm for aggregate particle size on 12 paper documents. There was similar pattern between single particle size and aggregate particle size of soot, which might provide the information of raw material for ancient ink. From infra-red and Raman spectroscopic analysis of sheet of writing on paper or wood, there was severe interference from background material (paper or wood). From Raman spectroscopic analysis of ancient ink carefully separated from ancient wood, spectrum pattern was closer to ink stick made by the soot from pine burning.
