  • To investigate the forest structure and to suggest a basic management data of the forest in the Kumsaenggol area of Wolchulsan National Park, thirty plots were set up and surveyed. According to the analysis of classification by TWINSPAN, the community was divided into the four groups of Quercus variabilis(I), Q. acutissima(II), Pinus densiflora(III) and P. densiflora-Q. acutissima(IV). From the results of the above, it could be determined that communities I and II were in a developmental stage of the ecological succession, in which the Quercus app. community progressed from Pinus densiflora. Additionally, communities III and IV are also in a developmental stage and will be expected to show competition regarding Pinus densiflora.

  • Habitat-forming species increase spatial complexity and alter local environmental conditions, often facilitating the assembly of plants and animals. We conducted a trait-based approach to algal assemblages associated with the freshwater bryozoan, Pectinatella magnifica. Association with algae leads to the inner bodies of the bryozoans being colored green; this is frequently observed in the large rivers of South Korea. We collected the green-colored gelatinous matrices and phytoplankton from waterbodies of the two main rivers in South Korea. Algal assemblages within the colonies and in the waterbodies were compared using the three diversity indices (richness, diversity, and dominance), and the composition of functional groups (FGs) and morphologically based functional groups (MBFGs) between the colonies within and outside of P. magnifica colonies. The most dominant and common species within the colonies were Oscillatoria kawamurae and Pseudanabaena catenata, both of which were assigned to the same FG (codon S1). Of the algal assemblages within the colonies, the dominance was higher, while the richness and diversity were lower, than those in the waterbodies. There was variation in the compositions of FGs and MBFGs in the waterbodies outside the colonies. Total nitrogen and orthophosphate led to dominance, and were significant factors for the variation in FGs in the waterbodies, whereas there were no such significant factors within the colonies. This trait-based approach to the community structure of associated algae provides the status and habitat gradient of these communities, which are stable, isolated, and consistent with the overgrowth of shade-adapted tychoplanktonic cyanobacteria.

  • This study aims to classify the biotope types based on the vegetation community in built-up areas by different land use and to map the plant communities. By classifying biotopes according to a taxonomic system, the characteristics of a biological community can be well-represented. The biotope classification indexes for the target area include human behavioral factors such as land use intensity, land-use patterns and land-cover types. The type classification was divided into four hierarchic ranks starting with Biotope Class, next by Biotope Group and Biotope Type and lastly by Biotope Sub-Type. The Biotope Class was first divided into two areas: the areas improved by humans and the areas unimproved by humans. The improved areas were again divided into permeable and non-permeable regions on the Biotope Group level. In the Biotope Type level, permeable paving areas were divided into areas with wide gap pavers and those with narrow gap pavers. The differential species of each biotope type are Lindera glauca, Conyza canadensis, Mazus pumilus, Vicia tetrasperma, Crepidiastrum sonchifolium, Zoysis japonica, Potentilla supina and Festuca arundinacea. The results of this study suggest that the biotope classification methodology, using a subjective phytosociological approach, is a useful and valuable tool and the results also suggest the possibility of applying more objective and scientific methods in mapping and classifying various environments.

  • This study was carried out to classify forest vegetation structure of Mt. Gaya from April to October in 2006 using phytosociological analysis methodology of Z-M schools. One hundred study sites(quadrat) were surveyed in the area. The forest vegetation was classified into 3 community groups such as Pinus densiflora community group, Cornus controversa community group and artificial forest group. P, densiflora community group was subdivided into 4 communities such as Rhododendron schlippenbachii community. Salix gracilistyla community, Meliosma oldhamii community and P. densiflora typical community. R. schlippendbachii community was subdivided into Potentilla dickinsii group(subdivided into Carpinus coreana subgroup and Melandrynum firmum subgroup) and R. schlippenbachiitypical group. Cornus controversa community group was also subdivided into 4 communities such as Hovenia dulcis community, Quercus aliena community, Ribes maximowicianum community and C. controversa typical community. Artificial forest type indicated 3 communities such as Larix leptolepis community, Pinus rigida community and Castanea crenata community. Accordingly, the vegetation pattern of the surveyed areas were classified into 3 community groups, 11 communities, 2 groups, and 2 subgroups and the forest vegetation was classified into 13 units in total. It is also believed that C. coreana subgroup and M. oldhamii community could be a source for a significant basic data for making vegetation hierarchy and forest distribution zone in the Korean peninsula. H. dulcis community was also considered to be one of the important genetic resources; therefore, those distribution areas are required to be institutionally protected and managed in the near future.

  • In order to make plan for landscape construction by ecological methods in Yukong R & D Complex site, environmental factors and structure of plant community were investigated and analyzed around Yukong R & D Complex site of Daeduk. The result of this study were as follows: 1. In the result by the classification of TWINSPAN and ordination (DCA) techniques for analysing of plant community structure, thirty plant community structure, thirty plots were divided into four groups according to soil moisture and succession trends were seem to be from the development of subsidiary vegetation through Pinus densiflora, Quercus spp., Robinia psudoacasia community to Q. acutissima community. So this result was proposed to validity of vegetation introduction for planning of ecological landscape construction in studied site. 2. On the analysis of environmental factors by ordination techeniques, the plant community were divided by soil moisture. Soilcondition will be fertilized by introduction of broad-leaved tree and the development of succession trends from the present state of plant community to Q. acutissima community. 3. The problems of horiticultural places happened to studied site, so horiticultural places for ecological landscape construction was proposed planting techniques that were considered to soil suitability, economical efficiency, native species and wildlife. 4. If we attempt to ecological landscape designs on natural systems and use natural processes to achieve desired end-points, we are more likely to produce self-sustaining solutions.

  • In the past, strong social bands, which had spontaneous communities, existed in Korean traditional society. However, while it's developing through industrialization; monolithic apartment houses were introduced which causes less interaction between neighbors. With the growing attention to the higher living quality, various schemes to revitalize the community spirits have been groped, including to improve in hardhearted neighborhood relationships and to cope with the dreariness in the city. With the development of the internet and the spread of 'digital home', the communities in cyber space have been especially revitalized since the information-oriented society. In a move to strengthen the communities in apartment complexes, this study tries to find the revitalization scheme for virtual communities in apartment complexes by analyzing the contents of its web sites and understanding the world of virtual community. These are compared and analyzed. The related virtual communities ("cafe" or "blogs") are also analyzed. The results are as follows. 1) There are some differences among the contents provided by apartment virtual community developing companies, still, it could be categorized into four types; "apartment complex introduction and management information" "community revitalization" "living guide" "individual services" 2) The contents provided by self-organized communities of residents neither require additional charge nor special membership for information while the formation is not systematized. 3) In the comparison of apartment virtual community developing companies with residents self-organized communities, "apartment complex introduction and management information" on freeboard, notice, request and Q&A, and "community revitalization" on communication board are both provided throughout the web sites. 4) The contents provided by apartment virtual community developing companies makes the information available in a wide range with managers, on the other hand, self-organized communities emphasize on showing attachment and concern of residents and requiring communications between neighborhoods.

  • Purpose: This study is to identify the implications and improvement solutions to plan the local community spaces bringing empty homes back into use that fit for regional characteristics, by analyzing the Empty Home Utilization Project implemented in Nam-gu, Incheon. Methods: Among 20 homes sponsored by the Project, five homes being currently operated were analyzed in depth, and features of exterior and interior spaces, and operational characteristics of the subject homes having been renovated through the project sponsorship were examined. Results: A plan is being established to systematically manage deserted or empty homes by assigning classification to each home in Nam-gu, Incheon and they are being utilized as a community space, a place of business or a cultural art space. Most of the physical improvements only included minor repairs such as redoing interior finish, as no major renovation was implemented including layout change and wall removing. Absence of major changes including improvement of house structure resulted in problems regarding accessibility and safety. Also, there was a limit to utilize the spaces only with support on physical improvement cost for empty homes, and it was identified that positive support for renovation should be conducted in accordance with its uses for the purpose. Implications: To complete the Empty Home Utilization Project successfully, it is most critical to reflect the resident opinions and demands, and discover local operators. Furthermore, for sustainable operation of local community space, additional plans for support would be required including financial support and training local leaders, consulting support for operation, encouraging community participation, and connecting with neighbor community.

  • This study investigated the actual vegetation and plant community structure of Geumsun valley and Weonjeok valley of Naejangsan(Mt.) National Park to provide the data for park management. As a result of analysis of actual vegetation, Quercus variabilis community(47.3%) and Quercus serrata community(17.0%) are widely distributed but Carpinus tschonoskii community(7.5%) and Zelkova serrata community(6.9%) are distributed in valley forests. Plant communities were divided into 6 communities of Fraxinus mandshurica, Carpinus tschonoskii, Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata, Zelkova serrata, deciduous broad-leaved mixture(Zelkova serrata-Lindera erythrocarpa-Acer palmatum), and Lindera erythrocarpa-Cornus walteri according to the analysis of TWINSPAN of classification using 20 plots($400m^2$). Geumseon valley is composed of boulder stone area of average slope $20^{\circ}$, and there were distributed Fraxinus mandshurica community of 86 years old, Carpinus tschonoskii community in age from 56 to 79, and Carpinus tschonoskii-Platycarya strobilacea-Zelkova serrata community in age from 48 to 71. Weonjeok valley is composed of boulder stone area of average slope $11^{\circ}$, and there were distributed Zelkova serrata community in age from 52 to 71, deciduous broad-leaved mixture community in age from 49 to 70, and Lindera erythrocarpa-Cornus walteri community in age from 43 to 51. Ecological succession of each community was predicted to maintain same state. The Shannon's species diversity showed from 0.8220(Fraxinus mandshurica community) to 1.3850(Carpinus tschonoskii community) per unit area of $400m^2$.

  • Purpose: This study, using the International Classification for Nursing Practice, aimed to identify the phenomenon of family nursing care, and the factors affecting it, for high-risk and frail older persons who have a significant need for home healthcare services. Methods: This study was conducted using secondary data collected by students who interviewed 93 healthcare subjects in a health center. The data was used to analyze the general characteristics, health-related characteristics, and confirmed problems of family nursing phenomena of the subjects. Independant t-test, Pearson correlation coefficient, and multiple linear regression were used for the data analysis. Results: The mean age of the subjects was 82.4±6.3 years. The most common problem of the family nursing phenomenon were unhealthy lifestyle, disturbance in family communication, and lack of family interaction in the community. People with greater family nursing phenomenon problems reported a higher degree of frailty and depression, lower quality of life and self-rated health. The factors that influence the family nursing phenomenon of frail older persons are the problems of mobility and hearing. Conclusion: Physical and psychological problems associated with aging can cause not only personal, but family functional problems as well. Therefore, a comprehensive family-oriented support program is required.
