In terms of both quality of rural lifestyle and cultural awareness, the importance of community facility is being emphasized. Nevertheless, by occasion of graying, population outflow and revenue loss, rural society faces the erosion of community. For these reasons, government is promotion an community space construction project on rural areas which is lack of community facilities. Whereas the projects are just one off thing not include upkeeping, so lots of functional overlapping community facilities are formed in same place. In this study has classified rural community facility remodeling element and designed rural community facility evaluation system of each elements. In order to implement of purpose, it has categorized community remodeling index in rural area by literature analysis and site survey. For setting remodeling rating system, this study analysed preceding research data and conducted a Delphi survey of 30 experts. As a result, this study deducted 29 categories of community remodeling index and 21 categorizes of remodeling rating clause. Taking this result, this study progressed case study on seonheul-ri in Jeju. Implications, limitations and future research directions are presented. It would be groundwork for remodeling system development in rural community facility.

Solid wastes are among the most pressing environmental and resource concerns in Korea. The Korean government has been implementing various management alternatives to reduce the production of solid wastes and recover valuable resources from them. Refuse-derived fuel (RDF) manufacturing facilities are one of projects that aim at recovering energy from solid wastes. This study used the emergy evaluation procedure to assess the feasibility of an RDF manufacturing facility in Wonju, Korea. By converting 10,442.6 tons of combustible solid wastes into 5,801 tons of solid fuel in 2007, this facility prevented the loss of useful resources with an emergy quantity of 3.70 × 1019 sej/yr. This amounted to a potential worth of 7.04 billion emW/yr. Total emergy input required to produce 5,801 tons of RDF was 5.91 × 1019 sej/ yr with an emvalue of 11.3 billion emW/yr. The Wonju RDF manufacturing facility contributed more to the Korean economy beyond its investment cost as revealed by the emergy yield ratio of 2.67. Direct emergy benefits and costs of the RDF facility were calculated as 1.20 × 1010 emW/yr and 3.31 × 109 emW/yr, respectively, resulting in the net emergy benefit/cost ratio of 2.62. This indicates that the RDF facility was a feasible option for managing solid wastes for the city of Wonju in Korea. This study demonstrated the usefulness of the emergy concept and methodology in evaluating management alternatives for solid wastes in Korea.

Emission characteristics of gaseous odor compounds emitted from the charcoal manufacturing process were investigated, and evaluated the odor removal efficiency of odor control devices. It was found that the measured odor dilution ratio of emission gases ranged from 10,000 to 44,814, which exceed largely the emission standard in the stack. Methylmercaptan, trimethylamine, hydrogen sulfide, acetaldehyde were turned out as major odor compounds of the charcoal manufacturing process. It was revealed that the odor removal ratio of odor control devices were very low due to the its improper maintenance and wrong design.
