자연환경의 보전이란 현재 잔존하고 있는 자연환경을 앞으로의 오염과 파괴에서 보호할 뿐만 아니라 이미 파손된 것이라 해도 과거의 원형대로 복원시키는 노력이 포함되고 있는 것이다. 다시 말해서, 경제개발이나 생산개발에 의하여 여태까지의 자연환경이 점차 파괴 또는 오염되어 가고 있음이 사실이나 이들은 곳에 따라 그 정도에 차이가 있는 것이다. 어떻게 말하면 급속적인 지역 개발에 의하여 자연이 오염 또는 파괴되어 가고 있는 것이 현실이라 하겠다. 그러나 이것은 보다 나은 인간생활의 현상을 위하여 자연을 개조하거나 극복한다고 할 수 있으므로 이로 인한 환경파괴 때문에 지역개발을 기피하여서는 안 될 것이다.(중략)

All work related to maintenance of track has been impletemented on the basis of the measured result from EM series cars in Korea. However, since these types of cars measure only versine value of the track irregularities instead of the real ones, this method will cause the confusion to maintenance operators if commercial speed should increase. This study was showing and explaining the program developed to get the real irregularities from the versine value. Finally, the reconstruction profiles completed by two different methods were compared with artificial track irregularities to confirm the their practicality.

The purpose of this study was to seek the spatial organization and prototype landscape through literature reviews, historical evidences, and field surveys for Donggwanwangmyo(東關王廟) shrine in Seoul. The results were as follows : First, the basic layout of the main buildings in Donggwanwangmyo which is the remains influenced by China had bilateral symmetry on the central axis between the north and south. Second, the Chinese forms and features were found at Jeong-jeon and middle gate in Donggwanwangmyo, and the symbolic elements of royal authority was also found in each space of Donggwanwangmyo. Third, spatial organization was classified as the entrance and the ritual area, and the entrance area was maintained by administrators and was used as the place of ritual ceremony preparation. Fourth, the original form of Donggwanwangmyo had been damaged due to the project for making urban park in the 1970s. The most of the existing trees and shrubs which are not suitable to the shrine should be removed to recover the original landscape of Donggwanwangmyo and chui-byoung(翠屛), pond, landscape facilities also needed to be restored. Fifth, Donggwanwangmyo needed to reorganize the pious atmosphere to recover of the shrine environment, and needed to be reclassified as historical site. Finally, some criticizes that Donggwanwangmyo is the result of Toadyism, but Donggwanwangmyo can be used as the valuable tourism resource through the awareness that Donggwanwangmyo was built under the situation of Joseon Dynasty, and organization and understanding that Donggwanwangmyo is a symbolic remains for the exchange between Korea and China.

This study regards a series of achievement on Wonlim(Garden) Cultural Properties Excavation Project, led by field of landscape architecture. It will mainly describe excavation results of Gwiam(龜巖: Turtle rock) and historical value of it in terms of Nakseojae(樂書齋) restoration in Bogil-do Yun,Seondo Wonlim(Scenic Sites, No.34). Gwiam(Turtle rock) was found 14.6m apart from the north of Nakseojae, and it covered with 10~15m topsoil tilted toward Nakseojae, The size of Gwiam, which was Granite, was 360cm length, 270cm width, 95cm high. The Edge of Gwiam's North west part was of triangular shape forming Turtle head. The back of the Turtle head was form of Tortoise-shell because of wide backboard with both side groove. The southeast part of Gwiam projected was Turtle's tail. This Granite was obvious Turtle shape artificially made, and there are less likely to relocate from place to place. This Turtle-shaped Gwiam is important landmark for Nakseojae, which is one of the four spiritual creatures written in Bogildoji(甫吉島識) and Gosanyugo(孤山遺稿) by Yunwi. According to Bogildoji, it is estimated that Gwiam were on the axis with Soeunbyung(小隱屛), Nakseojae and was buried when Yiguan(Gosan's grandson) reconstructed a building. Also, it was place for enjoying the moon. But, Even after three times excavation in Nakseojae, there was no way to identify further information regarding Gwiam, so it was a matter of mystification. As a result of this study, Gwiam is laid bare to light in at least 260 years, so it is good example for boosting importance of landscape architecture field and restoring Nakseojae. Furthermore, firm base-soil was discovered in 135m high Rock Mass below, so natural ground of Nakseojae can be estimated by this basis. To be conclusion, Preservation Process for Gwiam and Estimation Space through interpretation of four spiritual creatures(四靈) in Gosan's Poetry should be continue.

The Geumran-gasa (Kasaya) and Jangsam of the monk Samyeong are historical relics and were designated as object No.29, a Buddhist costume of the Joseon Dynasty, by the National Folklore Cultural Heritage, in 1973. In 1984, after being treated for the purposes of washing and preserving the shape of the garments, the object was kept in the Temple Museum of Pyochungsa, as their holding institution. However, regular inspection conducted by the Cultural Heritage Administration in 2013 determined the need for a re-treatment. The Geumran-gasa had been originally made with 25 strips, but it had been separated into two parts and many pieces were lost. A part of the collar in the Jangsam was lost as well. Therefore, both relics needed to be restored. The re-treatment process involved pre-investigation, washing, reinforcement fabric dyeing, restoration, and fumigation. In particular, we focused on reinforcing the damaged parts and restoring the missing parts by applying advanced materials and methods in order to restore the original form as much as possible. This conservation is the result of the re-treatment of the cultural properties by replacing the old material used in past treatments and applying advanced methods under the basic principle of reversibility in conservation treatment.

In this paper, we propose an efficient algorithm for mapping a $360^{\circ}$ circular image to a planar image. The proposed algorithm consists of obtaining size of the planar image, calculating the distance between the camera and the planar image, calculating horizontal angle of camera and planar image, calculating vertical angle between camera and planar image, calculating the position of a pixel that matches pixels in a $360^{\circ}$ circular image to pixels in a planar image. Experiments were performed to evaluate the efficient algorithm for mapping the proposed $360^{\circ}$ circular image to the plane image. The reconstruction rate of the mapped plane image was confirmed 99% and the image quality of the mapped plane image was confirmed 72%. Since the results were higher than the standard values of commercial software, the effectiveness of the algorithm was confirmed.

This paper presents plans to develop cultural archetype into a cultural industry. Though, various types of cultural products are being developed, they're not very popular to consumers and has very limited market. Reason for that is, most of these products are simple replicas of cultural assets or they are focused solely on restoring the traditions without considering trend. This study was focused on patterns found on the relics from mausoleum of king Mooryung of Baek-je. Main focus was the meaning of important patterns as generalized representation of traditional and emotional value. In addition, the study was done with the idea that developing the design of cultural products should be presented in modern style while carrying the traditional value and the story telling elements. The order of developing the design should be, first, forming process based on its original form and the elements, and developing a design motive based on the story the pattern is carrying. Then develop sample products with the motive.

In recent years, we have been working on the improvement project of mercury 3-lecture type at the Geummundo lighthouse for more than 100 years. We have installed toxic mercury removal, LED light source, and dualization system for nonstop. It can be seen as an example. Circular restoration of the entire frame is performed, and the real-time status can be grasped through the installation of the double-ball bearing and the remote control system. After installation, optical measurement through Hanvit secured the optical performance of 2,000,000 cd of floating brightness of 300cd, proving the efficient possibility of introducing the domestic rotary type light source using LED light source.
