The construction and management of the royal garden and landscape were the most significant project in Choson Dynasty. The kind of the royal garden and landscape were the rear garden of the palace, the groves of the royal shrine and orchard, etc. As the important project of the country, these constructions were controlled by the administrative system without division into the fields of engineering, building and landscaping. The purpose of this study is to investigate the administrative system. In particular, this study is focused on the construction and management of the royal garden and landscape in Hanyang from the 18th century to the late 19th century. This study is based on the analysis of historic documents and a survey of the relics. The results were summarized as follows : 1) The administrative system of the construction and management of the royal garden and landscape was composed of the government offices under Industry Board as a permanent organization - Yongjosa, Santaeksa, Chunchonsa, Songonggam, Changwonso - and Togam as a temporary organization. In addition to these organizations, there were Revenue Board, Ceremony Board, Military Board, which served as supporting organizations. The control of the construction and management of the royal garden and landscape was held by decision makers, executors of works and management. 2) The general process of the construction and management of the royal garden and landscape included Sangji and Kyuho다 as the first step; In case of buildings and facilities, according to former examples and drawings, the most of the planning and design was already fixed. In the case of landscape, those things aimed at construction according to the existing lie of the land. The works in the 2nd step; This process was divided into the construction of facilities and planting. In case of construction of facilities, those works were done by Togam and Songonggam. The high cost works were carried out through Togam and normal repairing works were completed by Songonggam. In case of planting, those works were carried out through Chunchonsa and the military. The management in the 3rd step; This process was done by two parts like the process of works. In case of facilities, management was done 효 the officers of Pongshim. In case of groves of newly - planted trees, this management was done by Tongsanbyonlgam and Tongsanjik who served cultivation and harvest of fruit trees as an expert.

This experiment was carried out to investigate the possiblity of harvest of the fruits of tomato and the tubers of potato by the graft cultivation in winter, simultaneously. One hundred percentage of the grafted explant between tomato and potato were survived. The yield of tuber was 2.178kg/10a in the grafted explant an d 687 kg/10a in potato. And the yield of fruits was 4,512kg/10a in grafted explant and 4,840 kg/10a in tomato and was decreased by 7% in grafted explant compared with common tomato, whereas brix of fruits was higer in the former than the latter.

본 기사에서는 기존 구조물의 구조를 변경하여 사용하는 경우 구조물 축소모형시험과 수치해석을 이용하여 안전도를 합리적으로 평가하는 절차에 관하여 지하철 정차장 구조물을 예로하여 살펴보았다. 구조물의 안전도를 평가하기 위한 구조물 축소모형 시험에서는 원형구조물의 실제 거동을 나타내는 모형의 제작이 가장 중요한 사항이다. 이를 위해서 적절한 상사율을 가지는 구조재료의 선정, 합리적인 경계조건의 설정, 실제하중을 고려한 재하방법 등을 결정하여야 한다. 구조재료의 선정과 모형의 축소율은 모형구조의 거동이 탄성범위 내인가 또는 극한거동인가에 따라 결정되는 것이 일반적이다. 안전도 평가를 위한 모형구조물의 제작과정에서는 원형구조물 거동을 수치해석을 통하여 예측하는 과정이 필요하며 이러한 사전해석(pre-analysis)을 통하여 구조물의 개략적인 거동과 측정항목을 정하며, 또한 합리적인 재하방법을 결정하게 된다. 모형구조물에 대한 재하시험을 통하여 원형구조물의 거동을 상사비를 적용하여 바로 예측할 수 있으나 재하하시험후 측정된 사항에 대하여는 모형구조물에 대한 사후해석(post-analysis)를 수행하여 측정값과 비교 검토하여 거동의 일치성을 입증하는 것이 일반적이다. 이런 과정을 거쳐 검증된 수치해석모델을 이용하여 실험에서 고려하지 않은 여러가지 하중조건에 수치적으로 검토할 수 있으며, 이를 이용하여 안전도검토와 적절한 대책을 수립할 수 있게 된다. 사전해석-모형시험-사후해석의 절차에 따른 구조물의 모형실험의 사례는 미국과 유럽에서 찾아볼 수 있으며 이를 통하여 수치해석기법의 발전이 이루어지고 있다. 현재까지 우리나라에서는 구조물 모형실험에 관련된 연구가 활발하지 못한 편이며, 상대적으로 경험이 적게 축적되어 있는 실정이다. 그러나 수치해석기법의 발전과 실제구조물의 안전도를 합리적으로 파악하기 위해서는 구조물모형 실험이 필수적이며 앞으로 연구가 활발히 이루어져야 할 분야로 사료된다.leic acid와 palmitic acid가 주요 지방산이었으나 싸리버섯은 중성지질에서 oleic acid의 함량이 높았다.n the part of special landscape management area, it is necessary to introduce landscape impact assessment system to more effective landscape management.ch served as supporting organizations.
