The physico-chemical and environmental factors of stoneworks were examined from March 2009 to October 2010, and aerial algae living on 24 stoneworks in Korea were identified. Fifty aerial algae were found in 24 stoneworks. Of the 50 taxa, 30 taxa were cyanophytes, 16 taxa were bacillariophytes, 3 taxa were chlorophytes, and 1 taxon was a xanthophyte. Nine species, including Aphanocapsa rivularis, which is known to only live in aquatic conditions, inhabited both aquatic and aerial environments. Synechococcus aeruginosus, Scytonema coactile var. thermalis, S. coactile var. minor, Stigonema ocellatum f. ocellatum, and Oscillatoria boryana were newly recorded in Korea. As a result of a correlation analysis between algae and the physico-chemical and ecological environmental factors, the taxa were divided into the bryophyte group, the humidity group, and the dry group. Although the bryophyte group was included within the humidity group, it was separated from the dry group. Taxa in the bryophyte group including Nostoc commune which was distributed in more humid areas than those in the humidity group. However, dry group taxa including Chroococcus pallidus were distributed in lower humidity than that of the two other groups. Correlations among other environmental factors were tested to identify other factors that could substitute for humidity and light intensity. As a result, tree distance, water distance, and plant coverage were replaceable environmental factors.

It is well known that the salt in stoneworks impact on damage of stone by various methods. Various kind of salt is detected in high content in the black surface layer of stone monuments and it is required about origin and roles of salts on blackening to considerate. In this study have been investigated the characteristics of salt in the black crust of sandstone and limestone which used in historical monuments in Berlin, Germany. Salt was analyzed for cation by Atomic Absorption and Atomic Emission Spectroscopy and for anion by ion Chromatograph. The representative ions are $Ca^{2+}\;and\;SO_4^{-2}$ in all samples and the most obvious combinations was proved in calcium sulfate by statistical methods. Because gypsum was detected by X-ray diffraction analyses in the black crusts, this calcium sulfate was confirmed by 2 hydrate type. The probable origin of Ca is air particle in atmosphere around sandstone and calcite in mother rock in limestone, and that of S is polluted air and mortar which used as conservation works.

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.

Korea's stone buildings are varied in their types such as stone pagodas, stone lanterns, stone bridges, stoneworks, etc. These account for more than 30% over the entire cultural properties, but research achievements are lacking compared to wooden buildings. Accordingly, this study aims to identify the shape, role and transition of Tapgu, which had been used to set up boundary at a stone pagoda, one of the stone buildings. The 20th stone pagodas, which have relative accuracy in its forming year, have been studied around national treasure or treasure between 7th century and 9th century. There are a lot of different opinions about the role and meaning of Tapgu, and at this writer's option, Tapgu is defined as follows: First, each structure plays a different role. A structure to pass the load in the upper part to the ground can be seen as a stair or a pedestal, but a structure to form double foundations can be considered as Tapgu. Second, Tapgu can be used to divide areas with stones or stepping stones. As a result, the shape, role and transition of Tapgu is as follows: Firstly, when it comes to its shape, Tapgu includes flagstone type, belt type, double foundation type, compound type. Flagstone type had been used to set up boundary at stone pagodas by using foundation stone, belt type by keeping apart from stone pagodas, and double foundation stone by installing dual foundation stones. Secondly, Tapgu is considered to set up boundary in the case of flagstone and plate stone, and acts like a structure which can prevent surrounding area of stone pagoda from coming up while being stuck around stone pagodas. Belt type was installed only for the purpose of forming boundary. At the bottom, double foundation stone had been used to pass the load in the upper part to the ground in the same way as the foundation stone in the upper part, and the boundaries were set varying the size. Thirdly, when it comes to the transition of Tapgu, flagstone type of boundary stone had been installed in the 7th century, and belt type of boundary stone had been mainly installed in the 8th century. And double foundation stone had been installed in the 9th century. Comprehensively, flagstone type and belt type had been made around the 7th and 8th century when Tapgu was regarded important and stone pagoda started to be built. At the turn to the 9th century, the role of Tapgu had been increasingly losing in the construction of stone pagoda, and foundation stone started to appear.

This paper aims to clarify the historical background and the architectural purpose of the buildings in NakSunJae area to the original state. Through the investigation, the clarified facts are as follows. 1. The relation with the buildings for the Crown Prince in the ChangDok Palace By constructing buildings in the NakSunJae area, the spatial conception of the Royal Palace was changed, that is, buildings for the Crown Prince in the ChangDok Palace disappeared and they became to belong to the ChangGyeong Palace. Moreover, by constructing the NakSunJae and its attached buildings, the area for the Crown Prince shifted to use as a private area for the king. 2. The date and the purpose of the construction The NakSunJae area is consisted of three compounds of building: NakSunJae, SukBokHun and SooKangJae. The NakSunJae was constructed for the king HunChong's private occupancy in 1847 and the SukBokHun for a residence of a royal concubine Kim, in 1847. The SooKangJae was originally built in 1785 in the SooKang Palace where the ex-king took up as his residence after abdicate the throne. Later on, it was repaired as the residence of the Queen SoonWon, king HunChong's grandmother, in commemoration for the 60th anniversary of her birth in 1848. 3. Architectural features of the NakSunJae area at the time of construction First, as the NakSunJae area is surrounded by quite high hills in northeast and by low hills in southwest, it is naturally distinguished from its surroundings and gives a cosy feeling. Second, the NakSunJae area shows very untrammeled style of arrangement in general, because it was constructed as a private occupancy for the king. other buildings are arranged in the latticing orderly, nonetheless, they are free by themselves from a strict form and make themselves an area full of variety. Third, the buildings in the NakSunJae area have a characteristic of naivety of common people's houses, because they were not an official but private place for the king, his concubine and his grandmother. Forth, the ornaments in the NakSunJae area are variously, elegantly and harmoniously patterned with the meaning of good luck. Fifth, back garden in the NakSunJae area was made by taking advantage of sloping hills. The back garden is beautifully configurated by arranging various constituent elements of pavilions, tiered flower beds, chimneys, decorated walls, small doors between walls, stoneworks and trees.

The purpose of this study is to investigate conservation and management methods of the Joseon Royal Tombs under the Eastern District Management Office. Through the literature survey, we understood the process of change of Joseon royal tombs, and through field surveys and interviews, we understood the status of the interior and the surrounding area. In this process, topography, land use and flow of human traffic, architecture and stone objects, water system, historical forests, and facilities were set as the main evaluation indicators. Urbanization has damaged the original terrains of Royal Tombs as national roads, buildings and facilities have constructed in the inner and outer area of Joseon Royal Tombs. Construction of underground passage, land purchase, relocation and demolition of the buildings are required for the conservation of the Royal Tombs area, and then it is necessary to recover the original terrain. In the case of land use and pathways, there are many disconnection of the original ritual circulation, they should be maintained to remind the sacred atmosphere of the royal tomb. And It is necessary to collect accurate information on the lost buildings and stoneworks through literature survey and excavation investigation, and that investigations should be lead to the exposure or restoration of the ruins. Historical forests require periodic and ongoing monitoring and management, and it is necessary to establish new entrance area and appropriate facilities following the long-Term conservation and management plan. These plans should be classified into short, medium and long-Term projects according to urgency and securing financial resources with a long perspective to implement continuous and systematic projects.

The purpose of this study is to investigate conservation and management methods of the Joseon Royal Tombs in the Middle District. Urbanization has damaged many of the original terrains as many buildings and facilities have entered the inner and outer area of Joseon Royal Tombs. Land purchase, relocation and demolition of the building are required for the recovery of the Royal Tombs area, and then it is necessary to recover the original terrain. In the case of land use and pathways, there were many land use which harmed the sacred atmosphere of the area, and many disconnection of the ritual circulation, they should be maintained to remind the sacred atmosphere of the royal tomb. The water system should be changed to natural type canal, and it is necessary to collect accurate information on the lost buildings and stoneworks through literature survey and excavation investigation, and then lead to the exposure or restoration of the ruins. Historical forests require periodic and ongoing monitoring and management, and it is necessary to establish a historical and cultural museum that can provide to visitors information about Joseon Royal Tombs. These works should be classified into short, medium and long-term projects with a long perspective to implement continuous and systematic projects.

The agriculture of Korea was begun in the neolithic era partly and generalized around 4,000 B.C. Discovery of acorn and stoneworks used in agriculture in neolithic era in 8,000 B.C to 6,000 B.C suggests that prehistoric ancestors of Korean night use acorn, hazel-nuts, and haws, etc. as foods. Cultivation of chestnuts, peaches, plums, pears, and japanese apricots was found in Mahan, the tribal states, and in the period of three kingdoms and Balhae dynasty too. In the period of Koryo, pears, plums, japanese apricots, pine nuts, apricots, grapes, jujubes, gingko nuts, oranges, and citrons were cultivated and used in diet. Sejongsilrokjiriji(1454), a geography of the early chosun, and Sinjungtonggukyojisungnam(1492) show that they cultivated almost all fruits we are now cultivating such as hazel-nuts, haws, nutmeg nut, and so on. Loquats seem to be brought in the early chosun era and figs around 16th century. Pecans, sweet cherries were brought around 1,900 and recently tropical fruits like kiwis were brought in and used in a large scale. In addition, Some fruits were used in medical treatments. Fruits increase the pleasure of the diet and sometimes they are used as a measure of a standard of living. Fruits have been improved and used for a long time, their status in our diet will be maintained resolutly.
