Handmade hydrated lime has been used for preservation and repair of architectural heritage in Korea. However, the effect of the amount of water used for slaking quicklime on the physical and chemical properties of the hydrated lime, which is the result of the slaking process, has not been clearly understood. In this study, particle size distribution, chemical composition and crystalline phases of the hydrated lime are investigated by varying the amount of water used for the slaking. In addition, temperature history during the slaking process is examined. For this, various experiments, such as laser diffraction analysis, X-ray fluorescence, X-ray diffraction, thermogravimetric analysis, and temperature recording using a thermocouple, were performed. When the quicklime came into contact with water, its temperature reached $100^{\circ}C$ within 10 min due to sudden exothermic reaction of calcium oxide, and this temperature was maintained for about 30 min. The water to lime ratio influenced the cooling rate during the slaking process; that is, the more water was used, the longer it took to reach an ambient temperature. The amount of water for the slaking did not have a noticeable effect on the contents of major components of the hydrated lime such as calcium hydroxide and calcium carbonate, but when slaked with more amount of water, average particle size of the lime tended to decrease. The experimental results in this study can be used as references for developing guidelines on the safety or appropriate amount of water in the lime slaking process.

This study derived the design aspects by carrying out the case study of Neunggok prehistoric remains park, Ansansingil historic park and Yongjuk historic park to which are taken measures to preserve undesignated cultural heritages after studying the related laws & regulations and the systems as the design conditions of historic park preserving buried cultural heritages. The results of the study are as follows. First, according to the laws & regulations related to the historical parks, the historic sites should be preserved and utilized at the same time and can have history-related facility spaces, squares, rest spaces, exercise spaces, education & culture space, and convenience spaces. Second, by the space organization and the circulation system emphasizing only the preservation of buried cultural heritages, the feature-preservation space and the functional space are separated and due to not accepting the usage behavior considering peripheral land use, the effectiveness of the historical park was low. Third, the passive feature-preservation methods such as the preservation of the exposed site in architectural methods, the reproduction of the dugout hut, and the planting Royal azaleas or displaying stone after covering up the location of the pit dwellings with soil and the usage mainly for viewing have weakened the identity of the historical park. Fourth, the fence preventing users' access interferes experiencing the features, and the vertical structure protecting the upper part of the exposed features has overwhelmed the landscape of the historical parks. Fifth, it was difficult to figure out the feature space only by the texts mainly on terminologies and the excavation photographs presented on the information signs which introduce the buried cultural heritages.

In this research the issues of record management of national archives in Korea are classified into four categories: 1) improving the status of the Central Archives of Korea, 2) constructing a new national archives, 3) revising the law on the record management, 4) creating qualifications for a professional administrator for Archivist. 1) In order to strengthen the function of the Central Archives of Korea, it is very urgent to create a systematic mechanism in which the Central Archives oversees and administers public archives(documents) collected from all the public institutions not only under the Administration but also the legislature and the judicial authorities. 2) This paper suggests that a new National Archives should be a symbolic building representing Korea as archives. Considering the fact that Presidents archives will be a part of this new National Archives, it also suggests that artistic and decorative pieces which embody Korea's representative archives or people should be included in the building. The budget for these should be supplied by the government. 3) This paper looks at the matter of revising the law on Record Management in two respects: (1)strengthening the function of the Central Archives of Korea, (2)making it obligatory to produce archives not open to the public, or making a protection clause for secret archives. This paper proposes that the Central Archives of Korea will be able to collect all the public archives from all the public institutions, and to oversee and administer them by revising the 5th and 6th clauses of the current law on the record management. It also proposes that some laws which make it obligatory to produce archives for documents not open to the public, and which protect those secrecy. 4) Regarding the qualifications for a professional administrator for the record management, this paper suggests lowering the qualification a little to the bachelor's degree of the record management. Also it suggests taking into consideration the persons in charge of the record management in public institutions and acknowledging their qualifications after a certain period of training at the Central Archives of Korea or something like that. In addition, it classifies the ranks of the professional administrators according to their qualifications.

The Wooden Gamsil with Inscription of "Botajeon" in the collection of the Dongguk University Museum was made in imitation of the wooden architecture style of the late Joseon period. The Gamsil had suffered exfoliation in the pigment and loss of components and thus underwent conservation treatment. Prior to the conservation treatment, the damage was classified by type and form, scientific analysis was carried out on the fiber and the species of wood, and portable X-ray fluorescence (P-XRF) analysis was conducted for the pigment component analysis. According to the analyses, Korea Pine(Soft pine) was used for most parts of the Gamsil, Manchurian walnut (Jugalns spp.) was used for the signboard, and the fiber used was identified as rice straw (Oryza sativa). The P-XRF identified white lead and zinc oxide in the white pigment, red lead in the red pigment, ultramarine blue in the blue pigment, and emerald green in the green pigment. For the conservation treatment, contaminants attached to the gamsil were removed by both dry and wet cleaning, detached parts were reattached in their original places, and lost parts were restored.

This study induced ecological and cultural regeneration factors which can be introduced in island regions. And then, survey on recognition on importance was carried out with experts group. First of all, based on status and development trend of islands, farming and fishing village, ecological and marine city, eco-cultural regeneration factors fit to islands area were induced. Ecological regeneration factors were classified to land use, transportation system, buildings, and resources cycle. While cultural regeneration factors were classified to preservation, making tourism resources, and base facilities. This study compared recognition on importance by field such as occupation and major field. One-way ANOVA was used. As a result, this study compared recognition on importance about eco-cultural regeneration factors in island regions and suggested future direction.

As international criteria and standards are required in the fields of design and construction, landscape performance must also be considered not only for the value of the landscape but also for providing quality assurance and sustainability. Given the lack of research on landscape performance, the present research was purposed to analyze the importance of potential assessment categories and items using an analytical network process. A list of assessment items, which is composed of 20 items and 6 categories, was derived through a literature review and a preliminary survey of 11 landscape professionals. An ANP model was established and a survey was conducted among 30 landscape practitioners to determine the weight of priorities considering the criteria. The results of ANP showed that the categories of site selection, preservation and health, and convenience had high priorities while materials had the lowest importance score. For the assessment items, a monitoring plan was the highest importance, followed by cultural/ historic preservation, management cost reduction, and natural ground areas. Despite the difficulties in quantifying landscape achievements, most respondents agreed that there needs to be an evaluation system for landscape performance in order to assure the quality and sustainability of landscape development. More research and discussion are needed to develop an assessment system for landscape performance that is applicable to Korean context.

The Old Town of Daejeon has significantly gone down due to population decrease and vacancy of buildings. To resolve these problems, it is necessary to develop revitalization measures with unique features, but it is also important to use historical and cultural resources from a certain point for the regeneration of local community. The Old Town of Daejeon has a number of industrial structures and architectural heritages that give character to the spaces, but most of them are being impoverished without any use although they have universal value. This study examined the standards to evaluate the importance and value of modern industrial heritages as historical resources that contributed to the development of local community and discussed case studies to review the value and use of industrial heritages that laid the foundation of Daejeon's development as a modern city to address the needs for urban regeneration through preservation and use of modern industrial heritages. Also, the limitations of administrative efforts were identified and the solutions were sought to address the needs to gather efforts with local government offices and the private sector. In conclusion, this study suggests an active and open policies to use cultural heritages through the use of modern industrial heritages for the revitalization of local communities based on the study of policies for the communication of urban users and community cultural spaces, preservation of landscapes including industrial heritages, and preservation in connection to social organizations and social companies, and that it is necessary to provide policies followed by efforts, i.e., to arbitrate the owners.

This study was designed to suggest a landscape agreement in order to effectively preserve historical and cultural landscapes at this point of time when many landscape agreements are being concluded for landscape management, to analyze landscape management methods according to the problems of comprehensive and widespread landscape agreements and landscape types and to generalize landscape agreement contents. To begin, sustainable and practical landscape management plans that local people can themselves participate and carry out were proposed, based on historical and cultural landscape preservation guidelines extracted from the consideration of domestic and foreign cases about landscape management by citizen autonomy and participation. The guidelines considered what regional residents would follow by themselves, as well as what should be considered with regard to the accessibility and symbolism of a building's appearance and external spaces designed with the motif of historical and cultural landscapes. The guidelines also pay attention to the maintenance management of outdoor advertisements and facilities in order to maintain a pedestrian-friendly street environment which pursues designs in harmony with the existing historical and cultural landscapes. In addition, the recommended guidelines that are considered less important,are restricting the sizes of buildings, encouraging maintenance management of the details and external spaces to hide building facilities and block them from being exposed and including information about the use of nature-friendly materials, and the management of neon signs in the landscapes and lighting time during the night. These results demonstrate that local residents need to improve the landscapes and change their consciousness by themselves to maintain the historical and cultural landscapes with a sense of tradition.
