This research was carried out to keep a sharp look-out on changes of estimated unit power and material in landscape architectural construction in Korea from 1962 to 2007 and to suggest basic information for its desirable direction in the near future. The research results are as follows. At first, work classification of estimated unit power and material landscape architectural construction was included under the earth work and in 1974 it had the name which was called landscape architectural process with earth works, and in 1984 the estimated unit power and material of landscape architectural construction was separated from the earth work but it was still under name of estimated unit manpower and material of the engineering construction. In 1972 the estimated unit power and material began with a 'planting' and a 'pruning' and still consists of 7 work classification total: 'sodding and herbaceous sowing', 'digging out', 'planting', 'digging round the root', 'keeping and management', 'rubble masonry' and 'planting for protection of rocks split section'. The processes consist of 29 sub-processes in total. The lawn construction was mainly established in the 1960s, the planting construction in the 1970s, the keeping and management in the 1980s, split section protection in the 1990s along with new technology with keeping management in the 2000s. On the basis of these research results, the process to be added in the near future could be related to new material and new technology and the process might be much more subdivided.

The persons in charge of management request diagnosis and prescription to tree hospitals in order to get consultation about the problems like blight that occur in landscape tree management. This study aims to analyze what the main problems and questions raised by landscape gardeners are and those concerned in landscape tree management. This is done by investigating landscape tree-related questions and answers uploaded on the online consultation boards of the plant diagnostic centers approved in Korea including the Seoul National University Plant Clinic, the Chungbuk National University Plant Hospital, and the Kangwon Diagnostic Center. As a result, those concerned in landscape occupied the most as 81.4% among the questioners. However, only 11.5% did explain the plant management history or surrounding environment, which is essential for landscape tree diagnosis when asking questions. This shows that those concerned in landscape lack basic knowledge or interest about plant diagnosis. Among 263 questions about landscape trees, questions about physiological damage included 94 cases that were the most taking up 35.8%. Moreover, the next were damage by insects and damage by disease in order. It is thought that due to the characteristics of physiological problems that occur by various sorts of stress and with no signs, they tend to request diagnosis or prescription the most. The most frequent reasons for physiological damage are water stress and temperature stress. About damage by disease, there exist many types of diseases, and there are many complex damages accompanied by physiological causes. About damage by insects, the most common include damage by moths. In consideration of this result, universities or technician training centers should provide education for landscape tree management so that landscape technicians and students can acquire essential knowledge and information about landscape tree management and increase their interest in it. In particular, it is necessary to provide profound learning opportunities for plant physiology, and the technicians should make efforts themselves. In addition, it is needed to build organizations to which they can ask technical questions about landscape planting and management in order to understand landscape industry in general and the actual status of landscape planting technique and the actual field. Moreover, to elevate systemicity and expertise in the area of landscape tree management not yet equipped with the foundation, it is needed to cultivate the technicians intensively and conduct research by those concerned both in academic and industrial circles.

하구담수호는 하천의 출구점이 해양과 만나는 곳에 방조제를 건설하고 이를 통해 형성되는 인공호수이다. 출구점에 위치한 지리적 특성은 많은 수자원을 확보할 수 있지만 유역에서 발생하는 모든 유입량 및 오염물질이 유입되어 홍수위험 및 수질악화가 문제점으로 제시되고 있다. 담수호의 관리수위는 배수갑문 운영에 기초가 되는 수위로 용수공급, 홍수위험도를 고려하여 산정한다. 하지만 기후변화로 인해 가뭄, 홍수의 위험성이 커지고 있으며, 이를 고려하여 관리수위의 산정이 필요하다. 로버스트 의사결정 기법은 기후변화의 불확실성 하에서의 정책 결정을 위해 제시된 개념으로 불확실한 미래상황에 대하여 최적이 아닌 여러상황의 준수한 결과를 보이는 방법을 선정해 예상치 못한 상황에도 대비할 수 있는 것을 목적으로 한다. 본 연구에서는 담수호의 관리수위 산정을 위해 로버스트 의사결정 기법을 적용하였다. 관리수위 산정을 위해 미래 기후변화 시나리오는 CanESM5 GCM의 SSP1, 2, 3, 5 시나리오를 이용하였으며 담수호 관리수위는 기존 관리수위를 포함한 5개의 관리수위를 모의하였다. 각 시나리오에 따른 유입량, 호소수위 및 호소수질 변화를 모의하기위해 유역모형 HSPF와 호소모형인 EFDC-WASP 모형을 연계하여 활용하였다. 로버스트 의사결정 기법에 성능인자로는 신뢰도기반 이수, 치수, 수질지표를 활용하였으며, 결정인자으로 후회도를 활용하였다. 후회도는 로버스트의사 결정에서 널리 쓰이는 결정인자로 가장 좋은 성능인자와 그 대안의 성능인자의 차이를 의미한다. 최종적으로 최소의 최대 후회도를 갖는 시나리오를 1순위로 선정하였다.

국제화 시대에 대비한 조경수 생산기술개발은 어떠한 방향으로 이루어질 것인가? 조경수를 연구하고 있는 본인에게도 어려운 질문 중에 하나이다. 무엇보다도 국내의 조경수 생산기술 및 유통체계가 구축되지 않아 총체적인 문제점을 지니고 있기 때문이다. 이에 따라 현시점에서 국제화 시대에 대비하는 것이 우선적으로 나무의 수형, 비배관리, 수종선택이 필요하다.

Under the Korea Building Act, anyone planning to build a building or buildings on a site over $200m^2$ must plant plants over a specific area. In large scale development this rule is adhered to well, but such is not the case in small scale development. Therefore, special attention must be given to small scale development. Thus, the purpose of this research is to analyze the current situation and practice of planting at small scale development sites in Seoul, and then suggest policies for improving them. In this study using the data covering Seongbuk-Gu and Gangnam-Gu, which was surveyed in 2002, the current situation and practice of planting at small scale development sites was analyzed. After a questionnaire survey was conducted with government officers and building owners, the same analysis was made. Then the policies for improvement were extracted. The results are as follows: 1. In superordinate planning stage, because the minimum standards are too low, those must be strengthened. Any district plan does not control planting in private building lots. This requests active application of planting in private building lots as a design control measure in district planning. 2. In the building design stage, there are no guidelines. The obligation of building set-back between adjacent buildings by the Korean Building Act produces mass shaded and inferior planting beds. The act also is blocking landscape architects' participation in small scale development. And wall installations deteriorate the streetscape and growth of plants with shading. Therefore guidelines must be made. 3. In each stage of the building permit, the permit for building completion, and maintenance the Korean Building Act is blocking landscape architects' participation in small scale development, so the planting plan is completely handled by nonprofessional persons. Therefore, the act should be amended in order to make way for landscape architects' participation in each stage of the small scale development process.
