The objective of this study is to find out phytosociological characteristics of Quercus acutissima dominant forest in Anseong city. A total of 39 phytosociological relevés were sampled. 4 syntaxa were classified to use the Z.-M. School's methodology. Species compositions in which this study adopted were Oplismenus undulatifolius-Quercus acutissima community(typicum subcommunity, phytolacca americana subcommunity), Quercus acutissima community, Pinus densiflora-Quercus acutissima community. All syntaxa were distributed in a high proportion of synanthropophyte where lower-slopes with low elevations and inclinations. Oplismenus undulatifolius-Quercus acutissima community was mainly distributed in the west side of Anseong city where high intensity and frequency of human impacts was experienced. While in the east where most of the areas are covered mountains, Quercus acutissima community and Pinus densiflora-Quercus acutissima community were distributed. As a results, phytolacca americana subcommunity belong to Oplismenus undulatifolius-Quercus acutissima community is sytaxon that reflects change in species composition of Quercus acutissma dominant forest due to the continuous landuse changes in Anseong city.

This study investigated 62 nested quadrat plots of Jinaksan to identify community classification and changes of the vegetation by using the phytosocial method and analyzed importance values. Vegetation types were classified into 8 communities: Quercus mongolica community, Q. variableis community, Q. aliena community, Pinus densiflora, Q. acutissima, Zelkova serrata, Carpinis laxiflora, and C. tschonoskii. The significance value was highest in Q. mongolica (62.75) followed by P. densiflora (55.16), Q. variabilis community (25.03), Z. serrata (22.17), Q. aliena (18.30), Prunus serrulata var. pubescens (16.86), C. laxiflora (13.25), Q. acutissima (10.72), C. tschonoskii (10.08), Q. serrata (8.02), Fraxinus sieboldiana (6.93), Acer pseudosieboldianum (6.73), and Styrax obassis (5.73). Quercus mongolica displayed a stable distribution pattern, presenting a reverse J-shaped curve from the diameter at breast height (DBH) analysis, and it was judged that current state would be maintained for a certain period. In addition, P. densiflora is expected to dominate for the time being and Quercus species are expected to gradually decrease.

As quality of life improves recently, people began to pay more attention to outdoor environment and outdoor activities. In case of the U.S.A., community garden is utilized as space for plant cultivation and horticulture activities and the space is also used for complex activities such as education, play, leisure and rest. At the same time, such diverse activities are linked with creating social and economic wealth, thus creating sustainable values in the community. This study targets to identify the social and economic effects of community garden. For this purpose, the study analyzes the detailed cases of community gardens in the U.S. and analyzed the contents of the study based on the theory of social capital. In case of Korea, community gardens are operated in the form of urbane farming and parks in most cases but it is desirable in terms of contribution to the community and sustainability to manage the community gardens with space characteristics and programs that set up communities by gathering many residents in the community. It is necessary to approach the matter of community garden comprehensively and to set up comprehensive and complex plans to form community gardens. This study is expected to function as an important base for such purpose.

This study analyzed the factors affecting urban residents' expectations and participation in community gardens to present basic data of guidelines for community garden management. Urban citizens valued the necessity of community gardens overall, especially residents with outdoor gardens. The experience of private gardens was important in perceiving the need for community gardens, which are public spaces. The creation of community gardens had high expectations for social aspects such as improving quality of life, health promotion, and community revitalization. In particular, residents living in individual housing have high expectations for revitalization of the community, and community gardens can be a mediator for forming and maintaining local communities. Through this, the citizens' perception on the role and function of the garden as a community space could be examined. Expectations for quality of life, health promotion, and community revitalization are factors affecting the necessity of community garden. Participation was high in the creation and management of the community garden, and the necessity of community gardens, expectation for community revitalization, and expectation for environmental purification are factors that affect participation in the management of community gardens. The amount of donations that the residents are willing to pay for community garden management was KRW 75,222 /year on average. Overall, residents with higher need for community gardens and higher social expectation showed higher participation. Urban citizens have high expectations for community gardens, and they perceive the importance of social aspects more than personal aspects such as community revitalization and quality of life. As a strategy for increasing community involvement, it is necessary to set up the processes, determine participants' composition and roles, and establish a system to promote participation. Considering welfare aspects such as community revitalization and improvement of residents' quality of life, motivation and administrative support for participation in the creation and management of community gardens will serve as important factors.

The purpose of this study is to investigate the planning of the community spaces for sustainable apartment complex under the aging society. For this, it is needed to identify the practical meaning of community spaces for elderly residents. In many cases, existing apartments' community spaces have been designed without considering the elderly. In order to develop successful environment for aging society, it is necessary for us to precisely review how elderly residents are changing their needs. Survey and depth-interview methods were used for data collection of this study. This study was performed in the five subject apartments located in Haeundae new town, Busan. In planning of community spaces for sustainable apartment complex in the aging society, 1) The population of the elderly in apartment complex has been increased with progress of the aging society, and it has been necessary to enlarge and consider the aging-friendly community space. 2) When the community space is located in a good accessibility, visual openness, multipurpose composition and the center of complex, it was investigated that the degree of its usage was high. 3) Common apartment complex for the elderly was deficient, and the composition and the layout of community spaces were needed, which included sports facility, spaces for leisure culture and study. This study could be utilized as basic data for designing community spaces in apartments from the perspective of sustainable community.

Inorganic matters originated from stone quarries and manufacturing plants could alter the ecological characteristics of adjacent aquatic systems, especially the structure and function of benthic macroinvertebrate community. In such situation, the locality of stone quarry and the quantity of inorganic matters would be important factors that determined the disturbing strength to the benthic macroinvertebrate community. Locality patterns of stone quarries were classified into 3 types in relation to the stream ecosystem; stream-proximity, upstream-inclusion and tributary-inclusion type. In the result of species:abundance analysis, stone quarry B (upstream-inclusion type) showed geometric distribution, while others showed broken-stick distribution pattern. The benthic macroinvertebrate communities closer to stone quarries showed smaller species numbers and standing crops among all types of stone quarries. However the values of species evenness index were not seriously different between controls and directly affected sites. These results indicated that the effect of inorganic disturbance would differ from those of organic pollution that induced the highly dominant state occupied by tolerant species. Number of occurred species, standing crops, community indices and biotic indices indicated that the community of upstream-inclusion type was the most seriously damaged from the inorganic disturbance, and the community would be very simple and unstable. Tributary-inclusion stone quarry heavily damaged to tributary system in biologically, but influence to the main stream seemed to be depended on the scale of main stream. Among 3 types of stone quarry localities, stream-proximity type induced the least damages to benthic macroinvertebrate community, though the degrees of damage were different along with distances between stream and stone quarry.

This study was conducted to analyze the breeding bird community by using guild concept in Mt. Baekwoon Research Forest of Seoul National University. Bird Community was studied by line transect method during the breeding seasons of birds in 1982 and its results were compared and analyzed with the Park et al. Work in 1993. Guilds were characterized by nesting and foraging sites as follows: nesting guild - (H) hole, (C) canopy, (B) bush, (E) edge; and foraging guild - (o) outside, (c) canopy, (b) bush. Bush-nesting guilds such as Tricolor Flycatcher (Ficedula zanthopygia), Blue-and-White Flycatcher (Cyanoptila cyanomelana), Stonechat (Saxicola torquata), Bush Warbler (cettia diphone) and Skylark (Alauda arvensis) had disappeared after ten years. Outside-foraging guilds such as Common Buzzard (Buteo buteo), sparrow Hawk (Accipiter nisus) and Carrion Crow (Corvus corone) also were not observed. There was a sharp decrease of species richness of bush-nesting guild, canopy-foraging guild and bush-foraging guild compared to ten years ago. These decreases indicate that forest environment of this area has been changed for the ten years, and guild concept in this study can be used usefully to elucidate the change of bird community according to the change in forest environment.
