Biodegradation of the endocrine-disrupting chemical di-n-butyl phthalate (DBP) was investigated using a bacterium, Pseudomonas fluorescens B-1, isolated from mangrove sediment. The effects of temperature, pH, salinity, and oxygen availability on DBP degradation were studied. Degradation of DBP was monitored by solid-phase extraction using reversed-phase HPLC and UV detection. The major metabolites of DBP degradation were identified as mono-n-butyl phthalate and phthalic acid by gas chromatography-mass spectrometry (GC-MS) and a pathway of degradation was proposed. Degradation by P. fluorescens B-1 conformed to first-order kinetics. Degradation of DBP was also tested in seawater by inoculating P. fluorescens B-1, and complete degradation of an initial concentration of $100{\mu}g/l$ was achieved in 144 h. These results suggest that DBP is readily degraded by bacteria in natural environments.

The meaning of fengshui was another cultural ecological environment in the pre-modern in Korea. Village residents made interrelations with village natural environment by the medium of the geomantic landscape. The functions of cultural ecology through the village fengshui are as follows: the spatial location, the population inflow, the regulation of the community's production or construction or land-use, the adjustment of the environmental carrying capacity, the environmental management, the forming of the collective environmental perception and attitude. Village fengshui is a cultural adaptation strategy to the local environment for the village residents. Fengshui can be evaluated as a traditional cultural ecological way and knowledge system for keeping sustainable village environment in East Asia.

The purpose of this study is to research the characteristics of literature related to environmentally friendly for a village-focused green index. In order to make an assessment, keywords relating to green architecture were selected: environmental friendliness, ecology, sustainable, Noksaek (Green in Korean), green, and environmentally friendly. In addition, three keywords defining the scope of space were also selected: building, village, and city. Quantitative changes and contents of articles containing the keywords were analyzed. The result is as follows. First, 'sustainable' and 'ecology' were the terms most frequently used as parts of subjects and titles, respectively. Second, the studies relating to green architecture focused on villages mostly examine the actual conditions of the villages; criteria for environmental friendliness, analyses and evaluation of the environmentally friendly features of the village; and ways to establish a green, ecological, and sustainable village. Finally, when it came to establishing a village-focused green index, the environment, resources, and energy are shown to be very important elements. In addition, the term 'ecology' in a green index is shown to be significant for the management of the natural environment.

The landscape setting of a habitat strongly influences the distribution, abundance, and species composition of waterfowl. Thus, habitat assessment is very important to understand the habitat characteristics that sustain waterfowl assemblages. In this study, we hypothesized that the excessive use of artificial materials when new wetlands are constructed negatively influences wintering waterfowl. To test this hypothesis, we measured environmental factors, assessed habitat, and investigated waterfowl at 13 artificial wetlands in the Nakdong River Basin. There were greater numbers of waterfowl species and individuals in artificial wetlands with high habitat assessment scores. In contrast, environmental factors did not affect waterfowl distribution. In particular, features of natural habitats, such as macrophytes and sandbars, and the surrounding land-use patterns were important factors for sustaining waterfowl assemblages in each created wetland. Our results show that promoting naturalness in wetlands and surrounding areas would increase the species diversity and abundance of waterfowl. Further, complex habitats, such as wetlands and some terrestrial habitats, support both aquatic and terrestrial species because mixed habitats feature a larger array of food sources than more limited habitats do.

This study analyzed jackets by Alexander McQueen that have always pleased customers with traditional tailoring via every season's collection. This study categorized and then analyzed jackets by components such as silhouette, jacket length, collar, lapel, sleeve, shoulder line, and closure methods. To achieve the research goal, the study referred to photographs of 501 jackets introduced in signature brand collections by Alexander McQueen between 1996 and 2010. The analysis results on McQueen's jackets with the general components of the clothes indicated that the frequency of traditional tailoring components (such as lapels, tight sleeves, natural shoulder lines, and a button closing method) was higher than the frequency of designs of dramatic, deconstructive patterns examined by previously-conducted research. This shows that Alexander McQueen was cognizant to the responsibilities as a tailor and the basics of tailoring when developing jacket designs. This study also confirmed how McQueen enjoyed adding exaggerated jacket design components by making various use of details that emphasize drastic shapes like the hourglass silhouette, wing collar (that covers the shoulders), peaked lapel collar, kimono sleeve, bell sleeve, crescent shoulder, and pagoda shoulder.

The feeding ecology of endangered Cottus hangiongensis was studied in the Hosan stream from September 2006 to August 2007 by collecting them seasonally. The stomach contents of C. hangiongensis consisted mainly of aquatic insects and Nematoda, small fish, fish eggs, snails (Semisulcospira libertina), and small stones were also observed. The main aquatic insects in the order of relative importance were Diptera, Trichoptera, Ephemeroptera and Plecoptera. The most important prey items were Chironomidae sp.1 and Hydropsyche kozhantschikovi. Change in the main prey organisms by season were Trichoptera in the spring and the summer, Diptera in the autumn, and Plecoptera in the winter by ratio of dry weight.

The cultivated lands in metropolitan, such as Seoul, are quasi-natural areas that have been disturbed continuously by human being and is in needs to be preserved and to be managed than to get more crop production in the light of nature experience for civilians through conservation of biodiversity and landscape diversity. However, the cultivated lands in urban areas have decreased rapidly, being changed into developmental areas in its land use. This study is to review change of land use as time change of the cultivated lands in Seoul and to draw the landscape ecological characteristics and structure in the cultivated land after their analysis on the basis of biotope type map in Seoul. The ultimate goal of this study is for development of prototype to enhance biodiversity in urban drypaddy culture area on the results of these analyses.

This study is intended to evaluate the value of functional aspect from the viewpoint of habitat. The indicators that are used in biotope evaluations are various, but most of them use the criteria to evaluate the naturality. This evaluation method cannot appropriately reflect the functional characteristics coming from relation to the surrounding biotope. In this study, the connectivity, cohesion and diversity between individual biotope are quantitatively measured by a landscape index. It is hard to draw the functional value of individual biotopes because the landscape index related to connectivity, cohesion and diversity comes from a landscape having a number of biotopes. The concept of contribution was used to overcome this limitation. The concept of contribution is to quantify how much each individual biotope contributes to the connectivity, cohesion, and diversity in a certain range of landscape by deriving the amount of change in the landscape index according to the presence or absence of each individual biotope. In order to understand the characteristics of evaluation results in functional aspect, this research has done a comparative analysis of the previous research findings in the same target area. According to the result of the research, individual biotopes such as artificial forests, fragmented natural forests, and small planting sites were highly rated.

This study makes an attempt to appraise how much successful both (Ham-Pyung) Butterfly Festival and (Mu-Ju) Firefly Festival are in the view point of ecology-friendly effects, and based on this appraisal, searches for desirable and developmental directions of other eco-festivals. The empirical analysis of the study shows that even if the Butterfly Festival turns out to be more famous than the Firefly Festival, the latter is confirmed to be more eco-friendly than the former. The fact that the latter is more eco-friendly seems to be due to the fact that the subject matter, that is the theme, of the festival is the fireflies which are not only natural monuments but also peculiar in-site-resources specific to Mu-Ju. This fact suggests that the other eco-festivals, newly emerging ones in particular, need to find and designate in-site-resources inherent in their regions as the theme, as far as possible.

In this review, we aimed to synthesize the current knowledge on the observed and projected effects of climate change on the ecosystems of Korea (i.e., the Republic of Korea (ROK) or South Korea), as well as the main causes of vulnerability and options for adaptation in these ecosystems based on a range of ecological and biogeographical data. To this end, we compiled a set of peer-reviewed papers published since 2014. We found that publication of climate-related studies on plants has decreased in the field of plant phenology and physiology, whereas such publication has rapidly increased in plant and animal community ecology, reflecting the range shifts and abundance change that are occurring under climate change. Plant phenology studies showed that climate change has increased growing seasons by advancing the timing of flowering and budburst while delaying the timing of leafing out. Community ecology studies indicated that the future ranges of cold-adapted plants and animals could shrink or shift toward northern and high-elevation areas, whereas the ranges of warm-adapted organisms could expand and/or shift toward the areas that the aforementioned cold-adapted biota previously occupied. This review provides useful information and new insights that will improve understanding of climate change effects on the ecosystems of Korea. Moreover, it will serve as a reference for policy-makers seeking to establish future sectoral adaptation options for protection against climate change.
