The aim of this study was to study the functions and roles of Green Community Rediscovery Center (GCRC) in terms of community integration, to design GCRC with various types of green roofs, and to investigate the possibility of applying a renewable energy system (e.g., PV) to the building greenery systems. The four major functional modules for GCRC were suggested: implementation of ecopark and community gardens with environmental education programs, implementation of green housing model with education programs, Discover Science Center, and implementation of green business model with education programs. Three major functions of the center are also presented in terms of design: 1) functions of community gardens; 2) establishment of a green business model, community composting system and an urban farming system; and 3) roles of community gardens in social interactions within GCRC. GCRC provides residents with the opportunities of community gardens, urban farming based on a successful recycling system, as well as a green business model and environmental education programs near their homes. The air temperature of the green roof (utilizing Sedum sarmentosum as a cover plant) was approximately $3^{\circ}C$ lower than that of the non-green roof, indicating a potential efficiency increase in PV systems for GCRC. It was concluded that the GCRC suggested would enhance the neighborhood satisfaction, improve the quality of life and contribute to social integration and community regeneration.

To investigate the antimicrobial activity on bacteria causing a respiration disease and antioxidant effects of water extracts from 12 kinds of wild edible vegetables, we extracted the water extracts for 72 h in $7^{\circ}C$ using distilled water as solvent. The water extracts except Ixeris dentate and Allium monanthum had high concentrations of phenol compounds and flavonoids. Liguraia fischeri specially had the highest level on total phenol compounds and flavonoids with 205 ${\mu}g/mL$ and 98. 86 ${\mu}g/mL$, respectively. The each 0.05% extracts of Sedum sarmentosum and Liguraia fischeri had high effect on the DPPH radical scavenging activity among wild edible vegetables and the most extracts promoted antioxidant activity with increasing concentration of extract. The catalase activity of Erysimum aurantiacum and Aralia elata showed more than 150 units per g of fresh tissue. The effect of antimicrobial activity on water extracts showed characteristic activity. Only Staphylococcus aureus KCTC 1928 and Corynebacterium diptheriae KCTC 3075 were inhibited cell growth on the other hands, the remainder of bacteria was not inhibited cell growth. Nevertheless, the extracts of wild edible vegetables had specific concentration as MIC for antimicrobial activity respectively. In case of the extract of Aster scaber, Erysimum aurantiacum, and Allium monanthum had over 30% antimicrobial activity on the bacteria causing a respiration disease. In results, the wild edible vegetables include high concentrations of total phenol compounds and flavonoids that give a good antioxidant activity and antimicrobial activity. Therefore the wild edible vegetables are functional food for anti-aging and physiological activation.

The present study represents the screening of the protective effects of herbal methanolic extracts from Baekdu mountain against tacrine-induced cytotoxicity in HepG2 cells. Tacrine is an acetylcholinesterase inhibitor, and used for the treatment of Alzheimer's disease. However, administration of tacrine for the treatment of Alzheimer's disease results in a reversible hepatotoxicity in 30-50% of patients, consequently limiting clinical use. Therefore, studies for natural products with protective effect on the tacrine-induced hepatotoxicity would be valuable as providing potential therapeutic use. 109 plant sources were collected in Baekdu mountain, and extracted with methanol. These extracts had been screened the protective effects against tacrine-induced cytotoxicity in HepG2 cells at the 100 and 300 ${\mu}g/ml$. Of these, ten methanolic extracts, roots of Ampelosis japonica, aerial parts of Berberis amurensis, aerial parts of Sedum aizoon, aerial parts of Lespedeza tomentosa, aerial parts of Lespedeza juncea, aerial parts of Hypenricum ascyron, stem barks of Syringa reticulata, fruits of Gleditsia japonica, aerial parts of Chamaenerion angustifolium, branches of Ginkgo biloba, showed significant protective effects against tacrine-induced cytotoxicity in HepG2 cells.
