  • During the investigation of Korean indigenous fungi from Seoul, three genera-Fuscoporia, Porostereum, and Trametopsis, and four species-Fuscoporia senex, Phlebia acerina, Porostereum spadiceum, and Trametopsis cervina were found. Their morphological characteristics were examined and their identification was confirmed by molecular analysis based on internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA region sequences. These fungi are new to Korea and registered here with descriptions.

  • Arthrinium (Ascomycota, Apiosporaceae) is a major marine fungal genus. Three Arthrinium species were reported previously, but not fully described. We isolated the two species A. arundinis and A. saccharicola from Sargassum sp. brown algae in Jeju Island, Korea. These species have not been previously reported in Korea. We described these species in detail and performed a phylogenetic analysis based on the nucleotide sequences of the EF1-${\alpha}$ and ${\beta}$-tubulin genes.

  • Microbially induced calcium carbonate precipitation (CCP) is a long-standing but re-emerging environmental engineering process for production of self-healing concrete, bioremediation, and long-term storage of CO2. CCP-capable bacteria, two Bacillus strains (JH3 and JH7) and one Sporosarcina strain (HYO08), were isolated from two samples of concrete and characterized phylogenetically. Calcium carbonate crystals precipitated by the three strains were morphologically distinct according to field emission scanning electron microscopy. Energy dispersive X-ray spectrometry mapping confirmed biomineralization via extracellular calcium carbonate production. The three strains differed in their physiological characteristics: growth at alkali pH and high NaCl concentrations, and urease activity. Sporosarcina sp. HYO08 and Bacillus sp. JH7 were more alkali- and halotolerant, respectively. Analysis of the community from the same concrete samples using barcoded pyrosequencing revealed that the relative abundance of Bacillus and Sporosarcina species was low, which indicated low culturability of other dominant bacteria. This study suggests that calcium carbonate crystals with different properties can be produced by various CCP-capable strains, and other novel isolates await discovery.

  • This study aimed to investigate the dilapidated Fine View Square located in the city of Gangneung and analyze problems for building it into a sustainable space under an effective management plan. Further to creating an ecological base for restoring the natural circulation, a restorative method for the damaged area, a spatial assignment by the UNESCO's Man and Biosphere Programme (MAB), and an urban ecological park, we not only wanted to provide an environment that is citizen friendly, but also a practical and realizable project to connect with the various methods and programs mentioned above, while utilizing the Ministry of the Environment 's ecosystem conservation fund. In conclusion, we found that it would be possible to contribute to building an urban ecological park the Ministry of Environment proposed while restoring the lost natural circulation in Gyodong Square in the city of Gangneung and ecological soundness of the city along with the reduced heat island effect and the increased biological diversity and Ecological Soundness.

  • Current subway station's office employee must perform safety management tasks by monitoring the various safety management systems. But these monitoring systems are limited in effective situational awareness and response to a state of emergency immediately. It is necessary to develop an integrated safety management system display. In this study, we developed subway station safety management system's (CCTV, fire detection & alarm system, screen door control equipment) integrated prototype display with ecological interface design framework and evaluated prototype display interface's usability with GOMS model. The result was that the ecological interface's performance was better than existing safety management system's interface.
