본 연구는 인도네시아 그데 빨랑오 국립공원의 생태관광 활성화 방안에 관한 것이다. 인도네시아는 한국의 10대 교역대상국 중의 하나이면서 열대우림을 보유하고 있어서 생태관광자원이 풍부한 나라이다. 특히 자바섬 서쪽에 있는 군웅 그데 빨랑오 국립공원(Gunung Gede Pangrango National Park)은 유네스코가 세계생물권보전지역으로 지정할 만큼 생물다양성이 풍부한 곳이다. 이러한 장점 때문에 세계 각지에서 연구, 교육, 등산, 캠핑을 위해 다양한 탐방객이 군웅 그데 빨랑오 국립공원을 찾고 있다. 그러나 인도네시아는 탐방객을 위한 편의시설이 다른 나라에 비해 부족하고 탐방프로그램도 불충분한 상태다. 생태관광을 활성화시키기 위해서는 탐방시설의 물리적 개선과 다양한 탐방프로그램의 운영, 그리고 지역주민의 참여와 소득증대사업이 이루어져야만 한다. 본 연구는 군웅 그데 빨랑오 국립공원의 생태관광 현황 및 문제점을 분석하여 환경 친화적인 국립공원 관리와 생태탐방 시설의 개선계획을 수립하는데 있다. 이 연구는 이러한 제안이 한국과 인도네시아 사이의 실질적인 환경협력을 증진시킬 것으로 기대한다.

Natural disturbances and human development can cause habitat fragmentation. Plant and wildlife can become isolated, and habitat fragmentation and shrinkage have been recognized as a key issue facing the conservation of biological diversity. However, eco-corridors can alleviate the problem by providing linkages between isolated patches. The purpose of this study is to plan the eco-corridor for connecting urban forest via the urban stream with low cost and to restore the ecosystem. The results were as follows (1) Falco subbuteo, and Dryocopus martius inhabit in the study site. They are protected species designated by Korean Ministry of Environment. Thus the study site should be preserved as urban wildlife habitat species biodiversity (2) If the biodiversity of the study site is maintained properly, the eco-corridor can be constructed with low cost.

The diversity of spider communities was investigated in the pine forest of Pinus densiflora in Songri-san, where chemical pesticides had been applied to control pine gall midge (Thecodiplosis japonensis). Spider communities were surveyed in four areas: a pesticide-untreated natural forest (area A), a forest with vinyl-covered ground surface (area B), an aldicarb-treated forest (area C) and a forest treated with a systemic pesticide (phosphamidon) (area D). A total of 74 spider species from 17 families were collected from the four survey areas. There were 54 species from 15 families in area A, 27 species from 12 families in area B, 29 species from 9 families in area C and 34 species from 9 families in area D, respectively. The species diversity of spider communities was highest in pesticide-untreated area A, and much lower in the other three areas. The monthly species diversity of spider communities was highest in May and lowest in January. The similarity of the spider communities was highest in areas B and D. The monthly similarity of the spider communities was highest in November and February. The dominant species was Clubiona jucunda (12.71%, N=304 individuals). According to our results, the application of aldicarb and phosphamidon dramatically decreased spider diversity and the number of individuals in the forests. Thus, the application of these two pesticides to natural forests should be restricted, or alternative pesticides need to be developed. Our results also indicated that application of the pesticides should be avoided in May and June when high spider diversity is expected.

Small and large dams are installed in the course of a stream for maintaining the water level of the stream or obtaining agricultural water. Currently about 18,000 of them are installed in Korea to supply water. However, the environmental problems of small dams are well known : the interruption of stream eco-corridors, deterioration of water quality in the upper reaches of the small dam, changes in the habitats of riparian organisms, damages to the stream scenery. In a very few of these small dams artificial eco-corridors like fishways are installed, but the number is very minimal.Accordingly, to efficiently restore stream eco-corridors by removing these small dams, it will be necessary to closely examine physical impacts, such as changes in the riverbed and changes in the shape of the stream caused by the removal, chemical impacts, such as changes in water quality, and transport and accumulation of contaminated sediments and biological impacts, such as changes in the habitats of organisms, and develop related technologies in advance, and have these technologies verified through demonstration application in the sites. In this study, we analyzed the physical, chemical and ecological impacts of the removal of the above-mentioned small dams, and conducted a research on the demonstration small dam removal project for a spot investigation. As a result, the small dam removal will restore the eco-corridor, there by improving the habitat of fishes and crustaceans. The number of major underwater organisms inhabiting the Gokreungcheon, such as Korean spotted sleepers, Chinese minnows, Microphysogobio yaluensis, Abbottina rivularis, stone morokos, striped shinners, long-nosed barbels, and Chinese mitten crabs, is expected to increase, and the food chain in the ecosystem will improve so that species diversity will improve as well.

The purpose of this study is to consider the characteristics of fashion paradigm on contemporary fashion in pursuit of social change towards 'slowness'. As for the research methodology, literature survey has been undertaken. The results of this study can be summarized as followings. First, eco-friendly ethics towards sustainability is in taking action. The concept of 'cradle-to-cradle' is realized through reuse, recycle, organic material, and no use of chemical. Second, local diversity is revolving quality and longevity. Good quality of fashion made by artisans and specificity in local area is to be kept last. Third, people are recast in roles from simple consumers to self-made producers of their clothes. Users of clothes are more active and skilled role in practice of handmade, reform, DIY, and open-source design. In Conclusion, the fashion paradigm of 'slowness' is about designing, producing, consuming and living better to combine ideas for sense of nature's time, culture's time and people's time.

Off-flavor materials (geosmin and 2-methylisoborneol (2-MIB)) produced by microorganisms, such as, cyanobacteria and actinomycetes, cause freshwater use problems worldwide. Due to unpleasant taste and odor, these microorganisms have raised issues especially in drinking water resources. Recently, there has been increasing concern about 2-MIB and causal cyanobacteria, namely, Pseudanabaena, in Korea. However, material production and ecological dynamics remain largely unexplored. This study reviewed the distribution of Pseudanabaena, its species diversity, and the research trend of molecular ecology related to 2-MIB production in Korea. Based on published literature, we found that seven species of Pseudanabaena which include P. mucicola, P. limnetica, P. redekei, P. catenata, P. galeata, P. yagii, and P. cinerea appeared to occur in a variety of Korean water systems. All of these Pseudanabaena species were found in the North-Han River system (Lakes Soyang, Chuncheon, Uiam, and Paldang). Some of these species were also detected in other watersheds, but the precise species diversity was not identified. Species belonging to the Pseudanabaena genus are hard to classify through general microscopic alpha taxonomy, due to their very small cell size and similar morphological characters. Moreover, the potential of 2-MIB production cannot be detected by microscopic observation. Combining molecular ecological techniques, such as, environmental genomic materials (eDNA, eRNA) analyses to conventional methods could be useful to better understand the off-flavor material production and dynamics, thereby providing more efficient management strategies of freshwater systems.

Purpose: This study is designed to grasp how consumers' beliefs about the lunch box attributes such as healthiness, diversity, price, hygiene, and package eco-friendliness affect consumers' perceived value and purchasing behavior. Research design, data, and methodology: The data were collected from 615 respondents composed of men and women aged 20 to 59 who purchased lunch box products and were sampled using the quota sampling method. An online survey was conducted. The data were analyzed using the measurement model and structural equation model assessment with SPSS 24 and SmartPLS 4.0. Results: First, healthiness, diversity, hygiene, and the price had a significant positive effect on the perceived functional value of consumers, but package eco-friendliness did not significantly affect functional value. On the other hand, healthiness, diversity, price, and package eco-friendliness were found to have a positive impact on consumers' perceived emotional value, but hygiene was found to have no significant effect on emotional value. It was found that functional and emotional values significantly positively affected repurchase intention. Conclusions: This study confirmed that consumers' belief in the product attributes of franchise lunch boxes influenced consumers' perceived value, which thus formed the attitude of consumers and showed a relationship that affects repurchase intention. At the end of this paper, the managerial implications for the franchise lunch box brand, the limitations of this study, and future research directions were presented.
