Abstract:The major ten odorous compounds have been analyzed from four swine facilities in Jeju Island, in order to investigate the emission characteristics and odor contribution by different ventilation systems and manure treating types. From the study, the concentrations of NH 3 and TMA were high at the enclosed ventilation and scraper type facilities in winter season, and the sulfur compounds (H 2 S, CH 3 SH, DMS, DMDS) as well as volatile fatty acids (PA, n-BA, n-VA, iso-VA) showed high concentrations at the enclosed ventilation type facilities during winter season. The concentrations of nitrogen and sulfur compounds were high at slurry manure treat facilities. However, the volatile fatty acids (VFA) were relatively high in the scraper type swine facilities.The odor quotients of n-BA were high at four swine facilities, therefore the volatile fatty might be considered as the major odor causing compounds. Moreover the sum of odor quotient (SOQ) was high at the enclosed ventilation and scraper type facilities, and the odor contributions by volatile fatty acids were high in all swine facilities.

-We examined plants that were used as temple food in Jeju from May 2011 to January 2012. Thirty-six temples participated in the study, and there were 58 questionnaire respondents. Fifty-seven taxa were used as temple food, which belonged to 27 families, 51 genera, 55 species, and two varieties. The most commonly used family-based taxa were eight species of Compositae, six species of Cruciferae, and four species of Umbelliferae. Ten species of woody plants and 25 species of Jeju native plants were also used as temple food. The most useful part was the leaf, followed by the root, leaflet, and fruit. A patent search showed that most of the surveyed plants were covered by intellectual property rights. Forty-eight species had food-related patents, 34 species had cosmetics-related patents, and 38 species had medicine-related patents. The purchase and procurement of Jeju temple food plants usually depended on the market or plant cultivation rather than the use of the plants. Gathering of wild herbs for temple food has been performed on a limited basis. Therefore, collecting traditional knowledge for the use of Jeju plant resources should be conducted under different conditions rather than through a temple-related study.
