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.

In order to efficiently detect community structure in complex networks, community detection algorithms can be designed from the perspective of node similarity. However, the appropriate parameters should be chosen to achieve community division, furthermore, these existing algorithms based on the similarity of common neighbors have low discrimination between node pairs. To solve the above problems, a noval community detection algorithm using closeness similarity based on common neighbor node clustering entropy is proposed, shorted as CSCDA. Firstly, to improve detection accuracy, common neighbors and clustering coefficient are combined in the form of entropy, then a new closeness similarity measure is proposed. Through the designed similarity measure, the closeness similar node set of each node can be further accurately identified. Secondly, to reduce the randomness of the community detection result, based on the closeness similar node set, the node leadership is used to determine the most closeness similar first-order neighbor node for merging to create the initial communities. Thirdly, for the difficult problem of parameter selection in existing algorithms, the merging of two levels is used to iteratively detect the final communities with the idea of modularity optimization. Finally, experiments show that the normalized mutual information values are increased by an average of 8.06% and 5.94% on two scales of synthetic networks and real-world networks with real communities, and modularity is increased by an average of 0.80% on the real-world networks without real communities.

The purpose of this study is to look at the elementary school teachers' practical experiences of change and knowledges in promotion of Education for Sustainable Development(ESD) process with Community of Practice(CoP) of teachers and Biographical Approach. ESD project of 'S' elementary school was started by Principal's recognition of further and that was practiced with a common theme over the course through various experiences in educational field with teachers' involvement and finally came to the changes in teachers' personal life and lifelong cognition. Through Community of Practice teachers could look the concept of ESD to a wide field of view and tried various activities in the classroom with students and also, as a further, were able to equip new professional competency with skills. Through the process of learning and experience teachers accepted the ESD philosophy as the engine of life and experienced that their long-term recognition was extended to the whole personal life and the global community.

In recent years, many research revealed plant-insect interactions are becoming unstable because of climate change, human activities and grazing effect. In this work, it is aimed to disclose that how climate of two different years is influencing on insect community at certain locality in Mongolia. The data on the insect community are collected, covering full flowering season from June to August in 2014 and 2015. In order to include all species of insects in Udleg Station, data was collected in three different sites. One of them was around edge of forest, another one was in ungrazed area or inside the fence that has been kept for more than 9 years and last one was in grazed area. Weather was a perceptible difference during two year's study. This climate differences significantly influenced on the insect community. In 2014, overall 305 insect species were recorded, in which 124 insect species in order of Diptera, 44 in Lepidoptera, 33 in Coleoptera, 31 in Hemiptera, and 73 in Hymenoptera were determined. But in 2015, these number of species noticeably decreased, and total 150 insect species were recorded, in which 58 in Diptera, 26 in Lepidoptera, 13 in Coleoptera, 12 in Hemiptera, and 41 in Hymenoptera were determined.

Depending on the mode of nutrition exploitation, major fungal guilds are distinguished as ectomycorrhizal and saprotrophic fungi. It is generally known that diverse environmental factors influence fungal communities; however, it is unclear how fungal communities respond differently to environment factors depend on fungal guilds. In this study, we investigated basidiomycetes communities associated with Quercus mongolica using 454 pyrosequencing. We attempted to detect guild pattern (ectomycorrhizal or saprotrophic fungal communities) by comparing the influence of geography and source (root and surrounding soil). A total of 515 mOTUs were detected from root (321) and soil (394) of Q. mongolica at three sites of Mt. Jeombong in Inje County. We found that patterns of diversity and community structure were different depending on the guilds. In terms of alpha diversity, only ectomycorrhizal fungi showed significant differences between sources. In terms of community structure, however, geography significantly influenced the ectomycorrhizal community, while source appeared to have a greater influence on the saprotrophic community. Therefore, a guildbased view will help to elucidates novel features of the relationship between environmental factors and fungal communities.

The idea that a school could take a role of educating each community personnel as well as students and the school building could be a center in a community is discussed in this paper. Also, as rental housings being included in the community and placed near school buildings, school facilities can be shared and cover the shortage of social welfare facilities. Thus urban social facilities including schools, social and cultural facilities, and rental housings should be planned as a bundled scheme. The objective of this Paper is to find the suitability of building a complex of school, gymnasium, cultural facilities, welfare facilities in school sites, and building rental housing in public building sites, such as cultural facilities and welfare facilities, gymnasium sites in the City of Pyeong Teak. It is found that this assumption can be proved when building a public school of 6 to 7 story or a rental apartment with a floor area ratio of 150% - 200%.
