  • International marriage is composed over 10% among total marriage in Korea. Korea is changing rapidly to the multi-cultural society. The researches need to inquire into what the state of 'ethnic communities of the immigrant wives as the minorities' is and how the immigrant wives build and develop the ethnic networks longitudinally. At the beginning, this study tried to know what kinds of social networks the immigrant wives use for the process of being married and for the adjusting to marriage and Korean culture. For the purposes of this study FGI and the interviews were applied for the immigrant wives and the specialist groups in metropolitan city DaeGu. 18 interviewees from Vietnam, China, Philippine, etc.. were collected by the snow-ball sampling. The social networks of the immigrant wives in DaeGu were mainly private, but were deterritorialized and reterritorialized actively. They managed the close relationship with their family members of motherland, and had the networks sticky with relatives, friends, and other immigrant wives from the same countries. Even though they acquired the Korean nationality, they have the transnational identities. But the internet environment of Korea can contribute to activate the social networks for the ethnic communities of the immigrant wives.

  • Global environmental changes have the capacity to make dramatic alterations to floral and faunal composition, and elucidation of the mechanism is important for predicting its outcomes. Studies on global climate change have traditionally focused on statistical summaries within relatively wide scales of spatial and temporal changes, and less attention has been paid to variability in microclimates across spatial and temporal scales. Microclimate is a suite of climatic conditions measured in local areas near the earth's surface. Environmental variables in microclimatic scale can be critical for the ecology of organisms inhabiting there. Here we examine the effect of spatial and temporal changes in microclimates on those of carabid beetle communities in Hyangnobong, Korea. We found that climatic variables and the patterns of annual changes in carabid beetle communities differed among sites even within the single mountain system. Our results indicate the importance of temporal survey of communities at local scales, which is expected to reveal an additional fraction of variation in communities and underlying processes that has been overlooked in studies of global community patterns and changes.

  • This paper examined the impacts of the regional developments and dwellers behavior on the Seacoast. Seacoast features a variety of landforms which are created by the action of waves and tidal flows. The coastal landforms are found mainly in the interface between land and sea. Although erosional landforms constitute prominent landscape features as sea stack, sea arch, and rock cliff do, it is nonetheless the depositional features such as beaches, tidal flats, offshore bars, deltas, sanddunes, and coastal plains that have various ramifications for human communities. Among these, beaches and coastal sanddunes are special in that their formation is attributable to the combined action of waves, tidal flows, and winds. The main line of discussion in this dissertation is concerned with the transformation of group of beaches sanddunes along the coastline of Chungcheong-Namdo Province. To some extent, the erosion of coastal dunes has been a global phenomenon. The degradation process occurs most actively when the spring tides attack beaches, berms, and foredunes. Also involved in the transformation of coastal dunes are factors of human agency. The extent, speed, and pattern of their morphological changes are a function of land-use pattern. The reclamation of swale and the exploitation of sands as construction material and silica sand, for example, ruin the feature of coastal dunes.

  • BACKGROUND: Antibiotics used in animal husbandry for disease prevention and treatment have resulted in the rapid progression of antibiotic resistant bacteria which can be introduced into the environment through livestock feces/manure, disseminating antibiotic resistant genes (ARGs). In this study, fecal samples were collected from the livestock farms located in Jeju Island to investigate the relationship between microbial communities and ARGs. METHODS AND RESULTS: Illumina MiSeq sequencing was applied to characterize microbial communities within each fecal sample. Using quantitative PCR (qPCR), ten ARGs encoding tetracycline resistance (tetB, tetM), sulfonamide resistance (sul1, sul2), fluoroquinolone resistance (qnrD, qnrS), fluoroquinolone and aminoglycoside resistance (aac(6')-Ib), beta-lactam resistance (blaTEM, blaCTX-M), macrolide resistance (ermC), a class 1 integronsintegrase gene (intI1), and a class 2 integrons-integrase gene (intI2) were quantified. The results showed that Firmicutes and Bacteroidetes were dominant in human, cow, horse, and pig groups, while Firmicutes and Actinobacteria were dominant in chicken group. Among ARGs, tetM was detected with the highest number of copies, followed by sul1 and sul2. Most of the genera belonging to Firmicutes showed positive correlations with ARGs and integron genes. There were 97, 34, 31, 25, and 22 genera in chicken, cow, pig, human, and horse respectively which showed positive correlations with ARGs and integron genes. In network analysis, we identified diversity of microbial communities which correlated with ARGs and integron genes. CONCLUSION(S): In this study, antibiotic resistance patterns in human and livestock fecal samples were identified. The abundance of ARGs and integron genes detected in the samples were associated with the amount of antibiotics commonly used for human and livestocks. We found diverse microbial communities associated with antibiotics resistance genes in different hosts, suggesting that antibiotics resistance can disseminate across environments through various routes. Identifying the routes of ARG dissemination in the environment would be the first step to overcome the challenge of antibiotic resistance in the future.

  • This study aims to find the association between community scales and perceived community family-friendliness among parents with young children. Communities were identified into three groups: metropolitan, small and medium-sized cities and rural, according to the degree of urbanization. The data were drawn from a sample of 1,038 parents who had at least one pre-school child. The data were analyzed by frequencies, means, GIS, ANOVA, and multiple regressions. This study compared the level of community family-friendliness both at the 'dong' and 'si' levels after controlling for the individual and household characteristics of the respondents. The findings of this study are as follows. First, after controlling for individual and household factors, the level of perceived community family-friendliness differed by the community scales. The parents in the small and medium-sized cities had higher scores on community family-friendliness than their counterparts in metropolitan communities. And parents in rural communities received had lower scores in community family-friendliness than those in metropolitan communities. The results also showed similar patterns for the 'dong' and 'si' models. While job and housing type were associated with the perceived family-friendliness of the community, other characteristics such as sex, age, educational level, monthly household income and home ownership were not.

  • This study was carried out to investigate vegetation of Rhododendron mucronulatum habitat in Mt. Biseul to recommend basic information for synecological characteristics and management methods. The survey was carried out from May to July, 2011 and totally 46 vegetation data including 42 families 93 genera 108 species 16 varieties and 5 forma were collected and analyzed. Among the investigated 129 taxa, the numbers of rare plant resources were summarized as 19 taxa; The rare plants designated by Korea Forest Service, the specific plants by floristic region and the endemic plants were listed as 3 taxa, 15 taxa and 4 taxa, respectively. Rhododendron mucronulatum habitat of Mt. Biseul was classified into 3 plant communities (Carex lanceolata-Rhododendron mucronulatum community, Potentilla dickinsii-Selaginella rossii community, Carex lanceolata-Quercus mongolica community). Carex lanceolata-Rhododendron mucronulatum community was subdivided into Tripterygium regelii subunit and Miscanthus sinensis for. purpurascens subunit by human interference degree. And synecology, syndynamics, synchorology of these plant communities were identified, and Site-species ordination analysis by Principal Coordinate Analysis (PCoA) reflected that human impact, soil moisture condition were main ecological factors determining the distribution pattern of classified plant communities. Therefore these plant communities correspond to quite distinctive 4 habitat types : unstable-dry type=Miscanthus sinensis for. purpurascens subunit, unstable-moderate type=Tripterygium regelii subunit, stable-dry type=Potentilla dickinsii-Selaginella rossii community, stable-moderate type=Carex lanceolata-Quercus mongolica community. Finally, through the vegetational diagnosis, proper management methods such as a limit on the access of visitors, planting of native woody plants after removing unwanted vines or grass were suggested.

  • This thesis explores the relationship between self-construal and online communication pattern. The Internet has changed human-to human communication. This study was to analyze how the self-construal was appeared and what relationship self-construal had with several variables: the motivation of the on-line community member, the on-line community's character, the communication behavior, the level of relationship between on-line community members- in on-line communities. The data was collected through the on-line survey research(N=79) and off-line survey research(N=255). The results lead us to conclude that the self-construals in on-line communities reflect two factors, which is similar to the off-line community. Nevertheless, self-construals in on-line communities are more complicated. In addition, uniqueness of self-construals which is the tendency to express the self and think connection with others critical is the important factor in on-line communities' communication. It is also central that the impact of self-construals on communication behavior is significant. I think this study was a small touch to explore cyber communication applying to self-consturals. And I hope this small touch would spread out and help to understand human communication as well as cyber communication.

  • A common belief is that human milk is sterile. However, the development of culture-independent molecular methods, especially Next Generation Sequencing, has revealed that human milk harbors diverse and rich bacterial communities. Although studies aimed at characterizing the microbiota of human milk have produced different findings, Staphylococcus and Streptococcus are presumed to be normal members of the microbiota. Factors that influence variation in the microbiota are unclear; however, the postpartum time, route of delivery, maternal obesity, and health status may be influential. The origin of the microbiota is a hotly debated topic. Human milk bacteria are thought to be introduced through bacterial exposure of the mammary duct during breast feeding and/or the entero-mammary pathway from the maternal gastrointestinal tract. Although the exact mechanism related to the entero-mammary pathway is unknown, it is presumed that bacteria penetrate the intestinal epithelium and then migrate to the mammary gland, dendritic cells, and macrophages. In this review, various relevant studies are introduced.
