Purpose: The purpose of this study is to shopping medium determinants and consumer behavior differences based on the value of consumption. Methodology: The subjects of the survey were adult men and women in their 20s or older living in Korea, and 283 valid responses were obtained. A Logit model was used to identify consumption value factors and shopping medium choices. A t-test was conducted to analyze the differences between consumer behavior based on preferred shopping medium (on/offline). Results: The inclusion of community-oriented factors such as eco-friendliness and social contributions lead to higher likelihood of choosing offline shopping. In addition, consumers who value self-expression and who are price sensitive are more likely to choose online stores. Conclusions: It was found that community-oriented factors lead shoppers to choose offline shopping, and the need for self-expression lead shoppers to choose online stores.

In the 21st century numerous universities continue to have an interest in building a more sustainable campus. The concept related to sustainable development and sustainability is applied to new master plan of university or university building planning. The field of sustainable development can be conceptually broken into three constituent parts: environmental sustainability, economic sustainability and social sustainability. The realization of sustainable development will become when considered eco-friendly life of users, not only environmentally friendly technologies. This study aims to research the method of sustainable access to university building planning in Europe and Canada. First, certification and standards will focused on acquisition Green Building Certification. Then we look at trends of sustainability based on users and community through the system of prior consultation between university and users. For the desirable development of the sustainable campus, the sustainable planning of campus should be investigated with campus community, members and local residents considering the generation, the preservation, the maintenance of existing building.

This study was complied to analyze the professional agricultural techniques level and to suggest a desirable direction for the professional education system for women farmer. The research was conducted by using in-field surveys and interviews. Data was gathered by questionnaire from 147 women farmer in five specialized crop regions: strawberry, cucumber, rose, apple, and oyster mushroom. The results obtained are as follows. First, the technique levels in computer usage and electronic commerce, machinery usage, pesticide and fertilizer utilization, facility automation, and eco-agricultural cultivation were low. Second, the demand for professional education, evaluated through technique level by standard management diagnosis, was recognized. Areas of concern included: cucumber (temperature control, carbonic acid gas control, grading, funds management), strawberry (light control, soil temperature control, irrigation watering, shipping), rose (temperature control, light control, funds management, cooperated management), oyster mushroom (growth cabinet sterilizer), and apple (flower bud pinching, defloration, fruit thinning, funds management). Based on the results of this study, the following are suggestions for the planning of a professional education system for women farmer. First, it needs to address formal education in marketing, machinery usage, facilities automation, and techniques in pesticide and fertilizer utilization. Second, it needs to be a multi- level program with appropriate terminology at every level which is suitable to each age and ability of women farmer. Third, it needs a more comprehensive manual developed by need analysis of women farmer and a larger lecturer pool for professional education.

This study investigated the community structure and seasonal variation of the fish assemblages on Jangbong tidal flat, Incheon, Korea. Fish were collected monthly using a small otter trawl from November 1999 to January 2001. Thirty-six fish species were recorded, with a mean density of 185 individuals and biomass of 2,594.3 gWWt. The most abundant species by number were Johnius grypotus (23.7%), Acanthogobius hasta (17.8%), and Cynoglossus joyneri (10.7%), while the dominant species by catch weight were Acanthogobius hasta (21.2%), Sebastes schlegeli (16.2%), J. grypotus (14.0%), and C. joyneri (10.8%). Cluster analysis and non-metric multi-dimensional scaling (nMDS) were applied to assess the seasonal fluctuation in the fish assemblages. Based on the result of the cluster analysis and nMDS ordination, the faunal group could be divided into cold- and warm-water specialist groups. The cold-water specialists included A. hasta, Acanthogobius luridus, Triaenopogon barbatus, Tridentiger trigonocephalus, and Liza haematocheila. The warm-water specialists were J. grypotus, C. joyneri, S. schlegeli, and Hexagrammos otakii. In conclusion, the community structure showed a distinct seasonal trend, which seemed to be related to the seasonal fluctuations in water temperature.

Objectives: This study aims to identify self-resilience factors that drive right dietary and food safety practices in middle school students. Methods: Data was collected from 438 middle school students in Daegu using a self-administered questionnaire in December, 2013. The questionnaire consisted of 81 items with the following categories: general information, self-resilience, right dietary and food safety practices. Statistical analyses to determine frequency, average, ANOVA, factor analysis, reliability analysis, and regression analysis were performed using SPSS 21. Results: The results of factor analysis indicated that self-resilience was classified into challenge, adaptability, patience and achievement needs, and right dietary practices were sub-grouped into family meals, experience of dietary life, eco-friendly, balanced food, economy and bad food control, and food safety practices consisted of management of bacteria, hand washing and eating off a plate, safety food and food purchasing. The score of right dietary and food safety practices showed significant differences by sex, grade, and school achievement (p < 0.05). The economy factor of right dietary practices was significantly affected by the management of bacteria (p < 0.001), hand washing and eating off a plate (p < 0.001), safety food (p < 0.01), food purchasing of food safety practices (p < 0.05). The challenge factor of self-resilience significantly affected family meals, experience of dietary life, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and safety food (p < 0.05). The adaptability factor of self-resilience was associated with factors such as eco-friendly, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and food purchasing (p < 0.05). Conclusions: This study suggests that dietary education programs for middle school students could incorporate food safety practices, and self-resilience such as challenge, adaptability, patience and achievement needs to be effective.

This study was carried out four times on 2005 and 2006, respectively May and October to understand the bird community and habitat using condition in the Daegu Bulnogoboon Jayeon Madang (DBJM). In this study, 34 species and 332 individuals were observed. The dominant species were Passer montanus 22.0%, Pica pica 18.1%, Hypsipetes amaurotis 6.02% and Sinosuthora webbiana 5.72%, and the species diversity was 2.797. With migration, the highest number and percentage to the lowest was residents 61.7%, summer visitors 26.5% and winter visitors 11.8%. Among 24 species which bred(check or possibility) in the DBJM, canopy was 50.0%, hole was 37.5% and bush was 12.5% in their nesting guilds. In foraging guilds in breeding season was canopy was 58.1%, water was 19.3% and bush was 16.1%, and in non-breeding season, canopy was 54.8%, water 22.6% and bush 19.3%. For the habitats of the birds in the DBJM, wetlands including reservoir area were used by herons, ducks and Hirundo rustica, grassland area was used by Sinosuthora webbiana, buntings and Passer montanus, and forest area was used by Streptopelia orientalis, woodpeckers, Hypsipetes amaurotis and tits. The number of species and individuals of birds observed in the DBJM was higher than other urban parks. We suggest that this was attributed to various man-made habitats such as wetland with reservoir, grassland and forest area constructed in the DBJM.

It is not clear to assume the history of dyeing by persimmon juice without an early knowledge of an accurate record. However, the beginning of persimmon dyeing in Korea is estimated to be around the $13^th$-$14^th$ century, even though there are no supporting records. On the other hand, there are definite records of persimmon dyeing in Japan from around the 17th century. Persimmon juice was originally used for fishing tools in both Korea and Japan, but upon entering the Modern Era it eventually transfigured into a dye for fabric. In Korea, persimmon-dyed fabrics were used for traditional clothing until it also became a popular choice for modern clothes in the 1990s. In Japan, persimmon juice was originally used for varnishing surfaces of household items, but it recently became a material for arts, crafts, and even apparels. The main difference between persimmon dyeing of the two countries is the presence and absence of the fermentation process. In Korea, persimmons are picked and water is immediately added to its juice to produce the dye. In contrast, Japan produces a fermented persimmon dye. As a result, in Korea the dye can not be preserved for long periods, whilst in Japan it is matured in the storage for 2-3 years. Today's pursuit of eco-friendliness and wellness has prompted an inclination towards natural material clothes. Therefore, it is necessary for both countries to push scientific research into improving the storage methods and colorfastness of persimmon-dyed products for the increase of use consumption in other areas of persimmon and arrowroot dyed fabrics, and the development of environment friendly materials.

Abandoned paddy field provides an excellent opportunity to improve the species diversity and habitat quality. Ecological characteristic on the changing of plant communities at different seral stages is a major basis data for ecological restoration. In this study, we investigated changes of the species composition and community indices on the plant community associated with abandonment of cultivated rice paddies. The ecological stability of the habitat was evaluated by using eco-floristic characters(Di; Disturbance index, AUI; Actual urbanization index). Survey sites were grouped into six stages(stageI (${\leq}3years$), stageII(3-5years), stageIII(5-7years), stageIV(7-10years), stageV(10-15years), stageVI(${\geq}20years$). Vegetation investigation was done from May 2009 to October 2012 and carried out phytosociological approach. The total flora were summarized as 176 taxa including 58 families, 127 genera, 157 species, 3 subspecies, 15 varieties and 1 forms. At each of successional stages, 64 taxa in stage I, 34 taxa in stage II, 84 taxa in stage III, 83 taxa in stage IV, 92 taxa in stage V, 23 taxa in stage VI were identified. Of the occurrence plants, the species with the highest r-NCD value were Alopecurus aequalis, Juncus effuusus var. decipiens, Persicaria thunbergii, Artemisia princeps, Salix koreensis and Alnus japonica at each stages. Herbaceous annual plants were dominated in the early stage, but its r-NCD value declined in the middle stage and the late stage. On the other hand, herbaceous perennial plants and Persicaria thunbergii, annual hydrophytes, increases in the middle stage. Woody plant and herbaceous plant which appeared in the forest edge increases in the late stage. Community indices correlate with successional stages. Richness and diversity index increase along the successional gradient. But dominance index decrease along the successional gradient. Evenness index was correlated with lower. In the ecological stability analysis of the habitat that evaluated by eco-floristic characters, stage I was the most unstable habitat. And the stability of the habitat has improved according to the successional stage.

We described a spatial distribution pattern and floral diversity on the Paspalum distichum community occurring at the ecological parks of Hwamyeong, Daejeo, Samnak, and Maekdo in the Nakdong river estuary. A total distribution area of P. distichum community was $303,462.6m^2$. Its largest area was found in Samnak eco-park ($185,910.1m^2$). The most richness of knotgrass patches in each ecological park was determined Maekdo eco-park (87). Cover class level-5 shows the largest area ($260,663.2m^2$). A total of 73 taxa (34 families, 55 genus, 65 species, and 8 varieties) were listed up on the P. distichum community. A welldeveloped population of knotgrass was found predominantly at sites linked into human impacts at the riverine floodplain, the stream courses flowing through the parks, and the man-made channels and wetlands. Finally we proposed an ecological management strategy for knotgrass population in the study area.
