  • To study the plant community structure of Chayang-chon area from Jangsudae to Hangyeryung in Soraksan National Park, 62 plots(each size 100m$^2$) were set up and surveyed. Six communities(Pinus densiflora - Populus caximowiczii community, P. densiflora community, P. densiflora - Deciduous broad-leaved tree community, Quercus mongolica community, Q. mongolica - Carpinus cordata community, C. cordata - Deciduous broad- leaved tree community) were classified by DCA ordination techniques. Q. mongolica community, Q. mongolica - C. cordata and C. cordata - Deciduous broad-leaved tree community were distrivuted over altitude 755m, and the others were distributed below there. In the community over altitude 755m, the succession that Q. mongolica community changed to C. cordata community have proceeded partly and otherwise C. cordata community and Deciduous broad-leaved tree community have been competing with each other. In the community with distribytion range from 500m to 560, high, P. densiflora community would change deciduous broad-leaved tree community forward.

  • A comparative study on the minimal areas and the community structures in pine IPinus densiflora) and oak (Quercus mongolica) frests was carried out. Basic tools used in the present study were species diversity and classical ayntaxonomy (Z.-M. School) of the phytocoenosis. Total 120 nest-quadrats in 40 stands situated at the syngeographical region of the Lindero-Quercion mongolicae were investigated. Each stand was classified on the basis of species combination, and species abundance was computed with net contribution degree (NCD). Composition ratio of plant-from and rate of actual species diversity (ASD) to syntaxa were computed for better interpretation of the minimal areas. Four syntaxa were structured: Saso-Quercetum mongolicae, Viola albida-Quercus mongolica community, Carex hummilis-Pinus densiflora community and Juniperus rigida-Pinus densiflora community. Their minimal areas were determined as 305, 196, 169, and 81 ㎡, respectively. Aconsistent regularity between species composition ratio and community structure in the multi-layered plant community was hardly found. The minimal areas increased linearly with increasing rate of ASD, and a phytocoenosis developed by diverse arboreta in the understory and shrub-layer should be investigated with larger sampling sizes.

  • As the living standard of citizens are improving and the demand for the quality of life is increasing, the demand for the facilities of welfare and convenience for varied ages rises. Besides, our residential environment is faced with the need for changing into the environment of integrated function of living, which holds health, leisure, culture, education, welfare, etc. Considering the present reality requiring the augment of welfare facilities due to our aging society, community integrated facilities are needed, which can contain welfare service for home-living citizens within residential circle and can accept diverse needs of residents. Accordingly, the study began in order to suggest a better direction for community integrated facilities' plan that considers all age brackets for aging society. The study is to figure out way of thinking what community space of 3 age cluster middle-age in the 30s~40s, preparatory senior citizen in the 50s and old age brackets in the 60s~70s. As methods for attaining the aim of this study, surveys of documents and questionnaire survey were simultaneously used. The result of the study, investigating the importance of a community among the members in the residential complex, showed that all the age groups have highly perceived its importance. All the age groups responded that leisure are important to the elderly. It indicates that importance of their social relations are within the residential environment and it proves that there is lack of facilities for leisure activities of residents in apartment house.

  • Small park in the community is a public asset that is commonly used by the residents daily and performs an important role to activate the community. The purpose of this study is to draw a small park plan through community participation. In concrete, this study tries to find out the demand of the residents about their small park plan, observe the changes in their demand in the process of debate and analyze the effect of the residents' participation. Small group workshop method was adopted in the study and three groups were set up and surveys were made in two stages. Two dimensional pictogram cards and three dimensional digital park formation tools were used. The results of workshop study indicated as follows: Firstly, residents wanted to have community farming garden, green house and flower garden to grow plants, natural walls and safe resting facilities. Secondly, individual and diverse opinions presented at first could be converted to common opinions through mutual exchanges of opinions in the process of debates. Thirdly, digital park formation program functioned well as an effective visual tool to draw the attention and quick responses of the residents and to reach an agreement. It is expected that the results of this study show the effectiveness of residents' participation tools in the process of drawing agreements in the community society that requires the residents' demands and agreement and this study will be usefully utilized in planning community spaces with residents' participation hereafter.

  • The Purpose of this study is to analyze the investigation of consumer's consciousness for Han-Ok construction of community facilities in an apartment housing. The contents of this study were largely composed of two parts; First was about concept and type of 'New Han-Ok type' public building. Second was about consciousness for Han-Ok construction of community facilities in an apartment housing. The result to this study is as following: 1) the concept of 'New Han-Ok type' public building should not only be defined in terms of cultural property or Han-Ok experience facilities but daily life and practical community. 2) the consciousness for Han-Ok construction of community facilities in an apartment housing was recognized affirmatively more than 75.9%. 3) the strengths of 'New Han-Ok type' public building was as following: daycare centers & small libraries & management office-use of eco materials, senior centers-traditional maintenance, community center-ease of daylight and ventilation. 4) Weaknesses of 'New Han-Ok type' public building was as following: daycare centers-security problem, senior centers-inconvenience of space, community facilities-inconvenience of facilities, small libraries-lack of storage space, management office-inconvenience of moving line. The conscious research for 'New Han-Ok type' public building should succeed for vitalizing for Han-Ok.

  • Allyl isothiocyanate (AITC), as a fumigant, plays an important role in soil control of nematodes, soil-borne pathogens, and weeds, but its effects on soil microorganisms are unclear. In this study, the effects of AITC on microbial diversity and community composition of Capsicum annuum L. soil were investigated through Illumina high-throughput sequencing. The results showed that microbial diversity and community structure were significantly influenced by AITC. AITC reduced the diversity of soil bacteria, stimulated the diversity of the soil fungal community, and significantly changed the structure of fungal community. AITC decreased the relative abundance of dominant bacteria Planctomycetes, Acinetobacter, Pseudodeganella, and RB41, but increased that of Lysobacter, Sphingomonas, Pseudomonas, Luteimonas, Pseudoxanthomonas, and Bacillus at the genera level, while for fungi, Trichoderma, Neurospora, and Lasiodiplodia decreased significantly and Aspergillus, Cladosporium, Fusarium, Penicillium, and Saccharomyces were higher than the control. The correlation analysis suggested cellulase had a significant correlation with fungal operational taxonomic units and there was a significant correlation between cellulase and fungal diversity, while catalase, cellulose, sucrase, and urease were the major contributors in the shift of the community structure. Our results will provide useful information for the use of AITC in the assessment of environmental and ecological security.

  • This article explores how to incorporate the topic of the global environmental crisis called the "anthropocene" into archives studies and connect it to ecological practical reasons. In order to encourage discussion of archival studies, which puts the environmental crisis at a kind of archive constant value, this study seeks to examine the possibility of a quality shift in archival studies based on ecology. This article aims to go beyond the pragmatism of preparing improvements to eco-friendly record management, which is recently claimed by the "Green Archive" in Western archival studies. It calls for a new concept called 'ecological archive', which theoretically combines a more archives-based and ecological paradigm, and its epistemological transformation. Specifically, the ecological approach of archives is first discovered in the discussion of archival studies and at the same time, through the "ecological turn" of archives emphasized by recent anthropocene discourses, the concept of "ecological archive" emphasized by this article is embodied. This study uses 'ecological archive' as a universal and theoretical framework for archives as a basic concept for building ecological 'living' archives. In other words, for the construction of ecological archives, we reinterpret and extend so-called democratic values for archives, i.e., post-custodianship, community archives, and archives of emotions. Finally, the records of foot-and-mouth disease killing burial sites, an important site and example of the anthropocene tragedy, exemplifies the methodology of the actual application of ecological living archives. The case analysis aims to seek a new qualitative shift in record management that adapts to global ecological transformation, while also emphasizing the documentation by archival activism in ecological field practices jointly organized by archivists and citizens.

  • While a concept on biotop or the urgency of its classification systems have been under discussion recently, this study aims to examine outdoor biotop classification systems for environment-friendly community. To this end, the feasibility of creating a biotop in the community and application elements were generated and biotops were classified and categorized. Then, elements that can be applied in consideration of traditional Korean techniques were generated and biotop classification systems and specific components in residential areas were reviewed. As for the result of this study, based on a preliminary draft prepared through literature review, considerations for biotop classification systems were taken into account. Then, based on classification criteria for biotop formats, biotop functions and biotop types, a second-tier classification system was developed. Criteria for biotop formats included surfaces, lines and points while criteria for biotop functions were large cores, small bases, corridors, stepping stones and ecological islands. Criteria for habitat types were divided to include natural forest, developed green areas, lacustrine wetland, palustrine wetland, shrubs, grasslands, linear habitats, vacant plots and practical green areas, which were sub-categorized. As for the biotop classification system, macro-classification divided biotops into three types-space, line and point-based on biotop formats. Meso-classification had five groups and micro-classification had 21 groups based on habitat types. Future studies should focus on the ecological features of each biotop categories generated in this study and their creation and management techniques to find many practical methods to create, protect and manage outdoor biotop for environment-friendly community.
