The purpose of this study is to improve interaction with the construction subject by analyzing the contents and contents of users' involvement in landscaping works. For this purpose, this study selected the Gwanggyo Residential Land Development District Public Landscape Project in Suwon, Gyeonggi Province. For four years before and after the completion, the opinions of tenants were used as research data. Both qualitative and quantitative analyses of 412 complaints received by the project implementation office and local government were conducted. As a result, first, the main purpose of suggesting opinions was 'demanding and expressing complaints', and there were many 'parks' and 'rivers'. In terms of content, "quality" was the most pointed out, but many kinds of trees, such as tree planting, ecological river construction, and pavement construction were also mentioned. Second, the extraction of key words from content analysis was the most common method. Followed by 'additional foodstuff' and 'moving to the toilet and management building'. Much of the point of view about dead wood has continued to be conspicuous in the process of waiting to be dealt with at the time of transplanting. Third, the validity of the contents of the complaints was evaluated as a five - point scale. Therefore, the opinions raised were unreasonable, but overall, there were more complaints with certain objectivity.

To understand the status of ferns' distribution of Gwangneung forest, flora survey was done during the period of April 2003 to November 2005. The results obtained from this study were as follows: Ferns identified and surveyed were 46 taxa including 9 families 17 genera 43 species 3 varieties were recorded in Gwangneung Forest. Hemicryrtophyte (H) was the most common dormancy from recorded in surveyed area. Epiphyte (E) and Hydatophyte (HH) were calculated as 4.3%, 2.2%, respectively and they were the lower value compared to those of other dormancy form. Consequently, $H-R_{3}-D_{1}-t$ was recorded as the most common life-form of ferns in Gwangneung Forest. Pteridophyta-Quotient (Ptph.-Q.) was calculated as 1.28 and it was the higher value compared to those of other neighboring mountains.

Mammals in Korea have been studied in various fields such as animal science, veterinary medicine, laboratory animal science, ecology, and genetics. As the importance of biodiversity has been emphasized recently, conservation and management of mammals have attracted much public attention. However, in spite of such an increase in scientific research and public interest, it is still difficult to find a report or summary to grasp the trend of mammalian research in Korea. The purpose of this study is to provide the basic data for future plans of the detailed research area and the related policies by grasping the research trends of mammals in Korea. Using text-ming and co-word analysis, we analyzed 392 mammalian research papers published in Korean national journals as of 2015. Our results showed that the number of mammalian research papers published in Korea has gradually increased and that the research target species have also become increasingly diverse. The major research areas identified through text-mining and co-word analysis are (1) evolution/phylogenetics/genetics, (2) environmental science/ecology, (3) embryology/reproductive biology/cell biology, (4) veterinary medicine related to parasites, (5) parasitology related to rodents, (6) bacteriology/virology, (7) anatomy/cell biology/laboratory animal science, (8) veterinary science related to morphology and anatomy, (9) animal science, (10) marine mammalogy, and (11) Chiroptera (bat) research. Environmental science/ecology has been the most active field among the 11 research areas in recent times, and the proportion of research has increased sharply compared to the past. Environmental science/ecology is the core of biodiversity conservation, and as the importance of biodiversity has been emphasized in recent years, researchers' interest in mammal ecology appears to have increased. We expect that the results of this study will be useful for future research plan and related policies on mammals in Korea.

Carpinus laxiflora communities are known as the climax forest community of the temperate zone of Korea. There are three Carpinus laxiflora communities in Seoul. The purpose of this research is to analyze the characteristics of Carpinus laxiflora communities of Seoul and supply basic data for establishing of a management plan. The research sites are Sahmyook University, Mountain Dobong and Jinkwandong. This study considers investigation and the analysis of communities structure, soil characteristics and the growth increment of trees. As the result of study, we could know that the growth increment of the Carpinus laxiflora trees of Seoul is decreasing recently because of soil acidification and so on. Also the vegetation disturbance is increasing because of naturalized plant. Oak wilt disease has appeared in the oak forest around Sahmyook University that is the largest Carpinus laxiflora communities area in Seoul. For that reason the open gap was appeared in forest, and the spread of naturalized plants has been increasing in the gap. Furthermore, the Carpinus laxiflora trees are affected by the Platypus koryoensis which is a kind of oak wilt disease. And so, Unless there is a specific management plan, the survival of Carpinus laxiflora communities are uncertain in Seoul. Therefore the management plan of Carpinus laxiflora communities is necessary such as precise investigation, annual monitoring, etc. For the conservation of the Carpinus laxiflora communities, it is necessary to establish the management plan of the biodiversity for Seoul area.

This study draws the following conclusions about the nature garden culture with crane that is a dynamic landscaping factor introduced into nature garden by analyzing the literatures on cranes written and landscapes painted in Chosun Dynasty. First, crane symbolizes such Buddhist, Taoist and Confucius media as appearance of Buddha, desire for Taoist hermit world and long life, and a solitary's life of proud loneliness. It has been recorded that crane was raised from the Three Nations Era till the Japanese occupation and Confucius scholars in Chosun Dynasty opened shows concerning crane or formed literature groups enjoying poems of it, and often using crane as their denial of going into government service. Second, in order to introduce crane to nature garden, people caught wild crane and made a fence and some kind of pond for their growth. In addition, crane was strictly managed by appointed slaves and they trained crane for dancing and then tended to allow a crane to play on the yard in terms of abstract meaning or got two cranes free in consideration of their ecology. Third, for more appreciation of crane and the expression of some symbolism matching for it, both plum and pine, which mean a solitary's life and long life respectively, were planted in nature garden. And, Confucius scholars in Chosun Dynasty also enjoyed their refined tastes with appreciation, napping, reading and playing the harp, accompanied by crane. As aforementioned, Confucius scholars in Chosun Dynasty did not only draw the meaning symbolized by cranes and write poems about such symbolic meaning, but also positively introduce crane into nature garden as a dynamic landscaping factor, so that they enjoyed synesthetic senses including looks, motions and sounds of cranes for their refined tastes.

Old-growth and giant tree is a nonrenewable resource with great value. The purpose of this study is to provide scientific and reasonable evaluations for the preservation and management of the old-growth and giant tree. Until now the research of old-growth and giant tree's value evaluation and authoritative index is so insufficient and imperfection. Combining with the particularity of the old-growth and giant tree, this study analyzed the main value factors of the old-growth and giant tree and objectively selected the evaluation indicators. According to the actual situation value appraisal model of the old-growth and giant tree was builded. The main value factors can be divided into economic value, cultural history, growing place, tree state, tree form, tree vigor, protection level, growth environment, tree species, tree canopy, and so on. The evaluate indicators can be selected and the indicators' weight can be calculate using analytic hierarchy process methods(AHP). Based on economic value and indicators' weight, tree's total value can be revealed. After calculation and analysis, Gyeongju Gyerim Zelkova serrata's value evaluation results is 491,503,300 won. The research results of this study can provide scientific basis and reference to the old-growth and giant trees' value appraisal and loss compensation, and arouse people's environmental awareness.

To provide the basic information for preservation and reasonable management plan of Abies koreana population, vegetation structure and growing condition by altitude were analyzed. Six sites($400m^2$) were set up along the Georim valley in Mt. Jiri from 1,000m to 1,500m. The importance value of A. koreana in tree layer was the highest at 1,400m(site V) and 1,500m(site VI), and that of Quercus mongolica in the other site was high. In subtree layer, the importance value of A. koreana was the highest at site VI which located at 1,500m above the level of the sea. In DBH distribution, A. koreana population distributed evenly at all DBH class(below 10cm, 11-20cm, 21-30cm, above 31cm). Since 2000, the amount of tree-ring growth of A. koreana at site I, II, III, IV, V, and VI were 1.002, 0.996, 1.752, 1.850, 1.198, 0.984 mm/yr, which has decreased slowly in time for 2000, except site III.

This study was conducted to provide on a basic information for maintenance of roadside trees and identify the links between environmental pollution and tree damages (Ginkgo biloba, Platanus occidentalis) in Daejeon City by analyzing photosynthetic characteristics, water use efficiency, chlorophyll fluorescence and chlorophyll contents by the regions and plants. The investigations were conducted at Chungnam national university(CNU) considered as the least air-polluted area compared to other study sites, Daedeok science town(DS) which a new road with little traffic recently was built around, Daehwa industry complex(DIC) and Daejeon station(DS) which an old road with heavy is located around. The photosynthetic capacity of the two species were highest in CNU and lowest in the DS. However the water use efficiency was highest on the contrary to the photosynthetic capacity in DS. Chlorophyll fluorescence and chlorophyll contents were highest in CNU and lowest in DS as the photosynthetic capacity. On all of the test, Ginkgo biloba shows the more favorable physiological responses than Platanus occidentalis.
