Wind holes or air holes, from which cool air blows out during the summer, but mild air comes out during the winter, have provided the phytogeographically important refugia for cryophilous or cold-loving boreal flora during the Holocene period. At present, wind holes are serving as a faraway disjunctive habitat for Pleistocene relict glacial floristic elements, and present an invaluable information to reconstruct the natural history. Present work aims to collate the nationwide distribution and relevant DB on the potential wind holes of Korea based upon media and literature sources, along with geographical informations, such as place name, topographic map, environmental geographical information, flora, monitoring data of Korea National Arboretum, and field survey data. Geographical information on sixty nine wind hole sites have compiled and analyzed on the basis of flora and presence of fossilized periglacial landforms, such as talus, block field, and block stream, and sixteen sites have thereafter carefully selected and scrutinized through field surveys. To maintain a sustainability of wind hole ecosystem, including their original landform, micro-meteorological phenomena and plant community therein as a refugia or habitat for relict plant species of Pleistocene glacial period, appropriate restrictions and preservation measures are required.

Species composition and abundance of zooplankton were investigated around Dokdo in the East/Japan Sea in autumn 1999 and spring 2000. Vertical and horizontal hauls of a bongo net ($300{\mu}m$ mesh size, 60cm diameter) were made to collect zooplankton sample. Surface temperature and salinity ranged from $24.2^{\circ}C\;to\;25.1^{\circ}C$, and from 32.9psu to 33.2psu in September 1999, respectively. In May 2000, surface temperatures were $13.9^{\circ}C\;and\;14.2^{\circ}C$ at stations of A1 and A8, and salinity was 34.5psu at both stations. Zooplankton community was dominated by copepods which comprised 61% (September) and 60% (May) of total numerical abundance, respectively. The next dominant groups were appendicularians (11%) and chaetognaths (9%) in September 1999, and other crustaceans (27%) and appendicularians (4%) in May 2000. The 15.7% (September) and 23.2% (May) of copepods were in the juvenile stage of copepodites. The most dominant copepods were Oncaea media (10.4%) and Clausocalanus sp. (8.2%) which preferred warm water in September. In contrast, cold-water copepods such as Pseudocalanus minutus (9.4%) and Metridia pacifica (8.0%) were dominant in May. The results of cluster analysis based on Bray-Curtis index showed that zooplankton community were classified into two groups which represented different water mass. The average abundance of zooplankton in September was 2.1 times higher than that in May, and species number of them in September outnumbered that in May by 29 species. Zooplankton community varied in associated with a characteristic of warm waters which affected marine ecosystem differently in the study area depending on seasons.

Increased attention has been paid to the presence of veterinary antibiotics in various environmental matrices due to their toxicological behavior in the ecosystem and development of antibiotic-resistant strains of pathogenic bacteria. In the this review, 37 target antimicrobials were selected based on annual sales of antibiotics for livestock in South Korea 2014. Also, extraction and clean-up methods for the determination of the antibiotic residues in liquid samples including water, milk, and honey were comprehensively reviewed in the literature. Solid-phase extraction (SPE) was commonly used as a pre-treatment method for the samples. Most of the analytes were extracted in acidic conditions (2.5~4.0) except for aminoglycosides, which were extracted in neutral conditions (7.0~8.0). ${\beta}-Lactams$ showed the highest recoveries in neutral pH due to their degradation characteristics in acidic media. Starta-X, Oasis HLB, and Oasis MCX were frequently applied as an SPE cartridge and Oasis HLB showed the highest recoveries for the majority of antibiotic classes. The homogenized honey and milk were extracted by mixing with acids for deproteinization. Solids and other interfering substances in the extract were eliminated by centrifugation followed by membrane filtration or SPE before injection into HPLC.

Pseudomonas fluorescens pc78 is an effective biocontrol agent for soil-borne fungal diseases. We previously constructed a P43-gfp tagged biocontrol bacteria P. fluorescens pc78-48 to investigate bacterial traits in natural ecosystem and the environmental risk of genetically modified biocontrol bacteria in tomato rhizosphere. Fluctuation of culturable bacteria profile, microbial community structure, and potential horizontal gene transfer was investigated over time after the bacteria treatment to the tomato rhizosphere. Tagged gene transfer to other organisms such as tomato plants and bacteria cultured on various media was examined by polymerase chain reaction, using gene specific primers. Transfer of chromosomally integrated P43-gfp from pc78 to other organisms was not apparent. Population and colony types of culturable bacteria were not significantly affected by the introduction of P. fluorescens pc78 or pc78-48 into tomato rhizosphere. Additionally, terminal restriction fragment length polymorphism profiles were investigated to estimate the influence on the microbial community structure in tomato rhizosphere between non-treated and pc78-48-treated samples. Interestingly, rhizosphere soil treated with strain pc78-48 exhibited a significantly different bacterial community structure compared to that of non-treated rhizosphere soil. Our results suggest that biocontrol bacteria treatment influences microbial community in tomato rhizosphere, while the chromosomally modified biocontrol bacteria may not pose any specific environmental risk in terms of gene transfer.

The purpose of this study is to assess pre-service elementary teacher's conceptions of environmental issues. 141 pre-service elementary teachers from local college participated in this study. We discovered that most of participants understood the possibility of technological abuse that could lead to environmental destruction. They also well understood the crisis of the Earth's ecosystem. Nevertheless, it seemed most of participants were not ready to take action to save ti. In addition, they also showed stereo-typically biased opinions about science, technology and their relationship with environmental issues. It appeared to come from media-oriented environmental education. Since pre-service teacher's conceptions could directly effect future education, it is necessary to establish a more systematic educational system for environmental education, for both pre-service teachers and students.

This study analyzed the characteristics of vegan fashion produced by H&M and ZARA with respect to materials, design, development, production, and marketing to create social value. The results of this study are significant because they can be used as a reference to develop a vegan fashion market. Regarding the research method, this study assessed the concept and status of veganism through a literature review and examined vegan fashion case studies by analyzing official websites and media content. The study's scope covers the period from 2005, when H&M was the first SPA brand to create a vegan product line, until 2019. The characteristics of Global SPA's vegan fashion were as follows. Regarding materials, alternative materials were developed and an expanded use of organic materials was implemented. Regarding design, development was achieved through design collaboration and upcycling. In terms of production, an animal welfare policy was adopted and a sustainable supply chain was established. Marketing employed a campaign aimed at encouraging increased consumer participation. The findings regarding the social value of H&M and Zara's vegan fashion were as follows. First, a cyclical economy was realized through circular recycling in the entire process of resource selection, production, and waste disposal. Second, because product consumption indicated the importance of ethical consumption and sustainable consumer participation, corporate financial activities were created based on shared values to accomplish the social outcome. Third, collaborations with luxury brands or vegan fashion designers built a collaborative ecosystem in which vegan fashions were released and consumer participation campaigns were implemented.

A palustrine wetland is a type of a wetland that prevails in Korea as well as an ecosystem that provides various ecological functions and has affluent biodiversity. This study was conducted to understand the characteristics of vegetation in a palustrine wetland by analyzing a life form and naturalized plants, in order to present the maintenance and utilization plan of a small wetland. A total of 249 taxa including 76 families, 188 generics, 209 species, 38 varieties and 2 forma were found at six investigated wetlands. As a result of the appearance ratio analysis, Therophytes (37.8%) with 94 taxa and Hemicryptophytes (31.3%) with 78 taxa were in order of life form, and Gramineae (14.1 %) with 35 taxa and Compositae (11.2 %) with 28 taxa were in order of family level. These were deemed representative vegetation in a palustrine wetland. Equosetum arvense, Phragmites communis, Commelina communis, Persicaria thunbergii, Arenaria serpyllifolia, Stellaria media, Erigeron annuus, Erigeron canadensis and Artemisia princeps var, orientalis were found continuously for a period of investigation in all sites. Equosetum arvense, Phragmites communis and Persicaria thunbergii were species with high appearance frequency. Especially, Persicaria thunbergii was construed high in a cover ratio in May as it develop first among Hydrophytes and form a canopy sooner than anything else. We found that a degree of naturalization and an urbanization index appear comparatively high in Yeongok-ri, Cheonan, Gangjang-ri, Asan and Yodang-ri, Hwasung, which is construed due to artificial interference, such as fanning, fishing, swimming and green-tour program. These results would be used to utilize in restoring a deserted and damaged wetland and to provide fundamental data in creating a wetland as follows.

As OTT services become popular worldwide, content IP expansion strategy has an important position in the platform media industry ecosystem where new content is constantly distributed. In particular, the method in which a successful narrative expands the elements constituting a specific world, that is, the Universe, is effective in reducing risk factors in content IP expansion and expanding content franchises. This study intends to examine how Marvel's cinematic Universe (MCU) is strategically performing content IP expansion while borrowing the multiverse concept and replicating and reproducing it by itself through narrative analysis of . As a result, the multiverse can reproduce an incomplete state by repeating the completed event, which can exist as another self-fulfilling content. At the same time, it can be an effective content IP expansion strategy in that each story can be produced because a single character can exist in multiple under the multiverse.

In recently, thanks to the development of computer and internet, and reinforcement of digital media literacy of ordinary people, many users of comics and animations recombine contents into various ways, including UCCs. In a glance, it seems these outputs violates the copyrights of contents. But in reality, they helps the growth of the ecosystem of contents market, with increase of contents users. The reason of these reproductions inclines the characteristics of animation media. Animation, which are constituted by plastic symbols, auditory symbols, and narrative symbols, and Comic, which supports stories of Animations, affects as 'Imaginary signifier'. These signifiers helps users of contents to dismantle and reassemble stories. These aspects are seen in doujin culture, animation soundtrack fandom, and voice actor fandom. But In this article, we will concentrate into cosplay culture. Cosplay culture shows more active appearances than another fandoms. In especially, cosplay stage and daily cafe show more active reproductions of characters and communications. However, they are done by youth fans, which has not enough financial abilities: therefore, events are not sustainable and discontinued. And they have another limits, like lack of opportunity of performance. In the reality of Korean society, which needs of community making by community member, and hybrid culture, comics and animation productions in Korea are in need of access positively and encourage reproductions of active receivers of animations.
