Culture Technology is the basic technology which produces cultural contents in a narrow sense. All nations do their best in order to create new contents which can form international and cultural sympathy. If a variety of contents are created by applying Korean proper cultural heritages, they will be creative and competitive internationally. Therefore, technology of original cultural restoration is an essential and crucial skill. In this paper, 'gilt bronze dragon-phoenix ring-pommeled sword', a cultural heritage of baekje age, will be restored to the original form digitally on the basis of three-dimensional shape-information processing technology and the scientifically analyzed data. First of all, data from three-dimensional scanning is revised using stuffing and smoothing methods after sampling, extracting characteristics, and align. Then, they are modeled in a curved surface with NURBS and B-Spline. Secondly, textures are edited by estimating the color of components and the quality of materials, and then they are mapped. Original form model which was made was revised and corrected by specialists' examinations. The digitally revised ring-pommeled sword was combined with information technology, and it can be used to revise damaged cultural heritages by constructing formal database of ring-pommeled sword with regard to age, area and type. It can be also used as educational contents in archaeology or preservation science and cultural contents such as movies, broadcasts, games, animations and so on.

Our goal is to verify how changes in water's hydraulic characteristics after urban regeneration stream can affect any possible transformation of its thermal environment. To that end, we analyzed changes in numerous physical characteristics the subject stream along with the meteorological factors and thermal environment affected by it. Cheonggyecheon was selected as our subject as it is a great example of successful urban regeneration stream. As for physical characteristics, we allocated Type I (0.0%) and Type II (20.2%), depending on the green coverage ratio. As for numerical characteristics, at the point of Ba in which the riffle ends, the water temperature fell by $0.2^{\circ}C$ and the flow increased from 0.7m/s to 0.9 m/s with the dissolved oxygen increasing from 0.5mg/L to 0.6mg/L. As for meteorological factors surrounding the subject stream, the temperature dropped from $1.1^{\circ}C$ to $1.4^{\circ}C$ on average and relative humidity increased from 6.6% to 8.7%. Furthermore, there was an irregular change in wind velocity. According to the result of the Wet Bulb Globe Temperature (WBGT), the change in the values of Type I and II inside and on the surface of the subject stream was negligible. The downstream temperature in Type I fell from $0.3^{\circ}C$ to $0.6^{\circ}C$ and by $0.8^{\circ}C$ in Type II. As for vertical cooling effect, the change of water level was 120cm in Type I and 140cm in Type II. As for horizontal cooling effects, the value of Type I was increased from the point of Ba where the riffle ends and the value of Type II was on a steady decline.

The present study has monitored the changes in the biodiversity of Dunchon-Dong ecological and landscape conservation area after the restoration of the wetland, identified and analyzed the threats to the ecosystem, and presented a management plan accordingly. In this area which was forests and rice paddies in the past, apartment reconstruction is currently underway, with some hinterland forests and wetlands remaining. When we look into the change in the floras, the total number of species was 193 in 2000 before the restoration, it decreased from 2004 to 2006, and as of 2019, it was 149, showing an increasing trend. The result of comparing the species that emerged before and after the restoration showed an increase in Cyperaceae herbs such as Carex maximowiczii and Carex dispalata growing in wetland areas within forests and Schoenoplectiella juncoides and Schoenoplectus tabernaemontani growing in areas within wetlands where shallow water is maintained. As a result of analyzing the change in the area ratio of each type of extant vegetation, the wetland native herbs formed the power at the highest ratio after the restoration. The change in the power of the wetland native herbs was on an increasing trend until 2007, after which it decreased much in 2010 and then gradually increased, showing values of 26.6% in 2000, 44.6% in 2002, 49.0% in 2005, 53.3% in 2007, 28.7% in 2010, and 37.3% in 2019. The cause of the decrease in 2010 was judged to be due to the vegetation management conducted to secure open water and remove organic matter in freshwater reservoirs. The amphibia which emerged from 2000 to 2019 was a total of 9 species including Hynobius leeshii, Bufo gargarizans, Kaloula borealis, and Rana uenoi. As a result of the changes in the emerging wild birds, the species diversity index before the restoration was 0.9922 in 2000, and the species diversity index after the restoration gradually increased to 1.2449 in 2005, 1.2467 in 2010, and 2.2631 in 2019. The amphibia and wild birds inhibiting in the Dunchon-Dong forest and wetland were judged to have increased through continuous wetland maintenance such as naturalized plant removal management, native plant maintenance, and open water securing management. For the ecosystem preservation management of the Dunchon-Dong ecological and landscape conservation area, it was suggested to minimize the impact of the Dunchon-Dong reconstruction project, reorganize the indiscriminate access roads adjacent to the wetland, and reorganize the main entrance to the wetland. For ecosystem restoration management, systematic restoration and ecological buffer planting were suggested to be carried out at the time of construction fence demolition.

The objective of this study is to analyze the types and current status of development projects that underwent environment assessment in recent three years and provide basic data to encourage environment-friendly development projects in the future. This study was conducted by analyzing the pre-environment review reports and environment impact statements of development projects that took place in Gyeonggi province. Key findings are as follows. First, a total of 2,465 development projects spanning $173km^2$ were undertaken in Gyeonggi province in recent three years. This is equivalent to three times of the area of Anyang city. Second, types of development projects were in the order of factories and industrial parks, road construction, town (housing estates) development, sports facilities and waste treatment facilities. Public projects accounted for about 30%, while private investment projects represented 70%, indicating that private sector projects were as twice as high. The findings of this study show that the development density of Gyeonggi-do should be examined as a whole in order to develop a comprehensive, long-term plan and harmonize conservation and development systematically in Gyeonggi-do in a holistic perspective.

This study identifies the basic personality types of subjects who use the healing garden and investigates their plants-preference. The purpose of the study is to provide a basic information about planting plan, considered as a main parts of healing garden. Survey results are stated as follows: First, the order of preference of instinct type tree is Prunus yedoensis, zelkova serrata, Phyllostachys Bambusoides. On the other hands, the order of preference of feeling and thinking type is Prunus yedoensis, zelkova serrata, Metasequoia glyptostroboides. Second, the order of preference of instinct type of flowers is Rosa hybrida, Hibiscus syriacus, Forsythia koreana. However, the preference of emotional type is the order of Rosa hybrida, cosmos bipinnatus, Helianthus annuus and the preference of accident type is the order of Rosa hybrida, Hibiscus syriacus, Helianthus annuus. Third, for the color preferences, instinct type prefer yellow color, feeling type and thinking type prefer red color. Lastly, when people view plants, most personality types are interested in flower firstly, and secondly type of tree and scent. In other words, we can assume that people are interested in the flowers, most noticeable in plants. This study will enhance the effectiveness of the healing garden by providing relevant information regarding healing garden planting plan. Future research should consider to widen the range of target of investigation in order to perform additional comparison analysis.

The objective of this study is to estimate the cost and benefits of street trees for their planting types, specifically, single row, single row+bottom, double row, double row+bottom. Different planting types are compared and analyzed by using Net Present Value (NPV) and benefit-cost ratio (BCR). Existing data are collected from the literature reviews for the use of meta-analysis method for estimating cost and benefit. The elements for analyzing costs are management and planting costs, and benefits are air purification, energy saving and landscape view. The discount rate is applied at a minimum of 3% and a maximum of 5.5%. The unit used in this calculation is km/year. The result shows that the net benefit is highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR is the highest in double row, followed by single row, double row+bottom, and single row+bottom. The BCR reaches the break-even point from 9 to 17 years depending on the planting types.

For this paper, a study targeting 9 forest patches in Dangjin to suggest for the wild birds, was conducted. The correlation between the emergence of wild birds and the forest vegetation was analyzed, and the patterns of forest vegetation for the improvement of species diversity were suggested by classifying wild birds and foraging guild by the type of forest vegetation. As for the characteristics of the wild birds emerged, more species and bigger population appeared in the vegetation type of mixed stand forest where the natural deciduous broadleaf trees and evergreen needleleaf trees coexisted in the large scale vegetation area. Thus, it was known that the advent of summer migratory birds and resident birds were affected the most by forest patches and vegetation types. As for foraging guild, the larger the forest paches the more the species and the population of the wild birds inhabiting in shrubs and bushes.

The purpose of this study is to reconstruct the wooden frame structure of Buddhist temple, Kumdang in Youngamsaji which assumed to be built in the 9th century of Unified Silla Dynasty. The remaining site of Kumdang in Youngamsaji is investigated thoroughly with a particular attention to bay size and column distribution. The five ancient Buddhist temples which were built in the same period also have the same frame type as Youngamsaji Kumdang. These five ancient Buddhist temples and Kumdang in Youngamsaji are meticulously investigated in terms of their bay sizes and measuring modules. The framework schema is devised as a conceptual tool to conjecture wooden frame structures of Buddhist temple. A theoretical differentiation between frame type and frame structure is attempted to formulated a wooden frame structure as a stepping-stone for the reconstruction of traditional wooden building. The wooden frame structure of 9C Kumdang in Youngamsaji mainly follows the oldest Korean wooden pavilion, Muryangsujeon in Busuk temple, with a hip and gable roof. The wooden frame structure of 9C Kumdang in Youngamsaji is reconstructed through 3D computer modeling to such an extent that every wooden components of the structure can be 3D printed. The reconstruction also takes reference from the Cai-Fen system in Yingzao Fashi.
