전주시 외곽의 농촌지역(행정구역상 동)을 대상으로 4계절에 걸쳐 도시고형폐기물의 발생량과 물리적 특성을 연구하였다. 도시고형폐기물의 특성을 평가하기 위해 2개 지점을 선정하였다. 본 연구에서 얻어진 결과는 다음과 같다. 조사지역의 도시고형폐기물의 발생량은 0.597kg/cap./d로 전주시의 0.907kg/cap./d에 비해 낮은 값을 나타내었다. 조사지역의 도시고형폐기물중 가연분은 63.8~64.3%의 범위를 차지하고 있었다. 가연성 폐기물의 물리적 성상은 음식물, 채소류, 종이류, 나무류 등으로 구성되어 있으며 이중 음식물이 차지하는 비율은 46%로 나타났다. 재활용성 폐기물은 16.5~19.5%로 조사되어 전주시의 배출량과 거의 유사한 값으로 나타났다. This study was carried out to investigate the generation rate and physical properties of Municipal solid wastes(MSWs) during 4 seasons in agricultural village in Chunju city. The Number of sampling sites for the estimation of the characteristics of MSWs is 2 in agricultural village in Chonju city. As a results, generation rate of MSWs was 0.597kg/cap./d on the weight basis. This was Less than that of Chonju city, which was average 0.907kg/cap./d. The composition of food waste was 39~46%, and combustible wastes was 63.8%~64.3%. Most of combustible wastes are composed food, paper, wood, other wastes. Recycle waste of MSWs was 16.5~19.5%, which was similar to Chonju city.

The aim of this study was to compare the antioxidant activities and functional contents of Korean conventional and Chinese seed gingers from the Jeollabuk-do Wanju and Chungcheongnam-do Seosan regions. Ginger samples were subjected to steaming treatments for different durations (2-8 h) at 121℃ using an autoclave. The antioxidant activity was evaluated by measuring total polyphenol and flavonoid contents and ABTS and DPPH radical scavenging activities, while functional ingredient contents were analyzed for gingerols and shogaols. The results showed that Wanju conventional seed ginger (WO-2) had the highest total polyphenol (85.24 mg GAE/g) and flavonoid (98.14 RE/100 g) contents, surpassing that of the control in all steamed groups at 6 h. ABTS radical scavenging activity showed a strong correlation with total polyphenol and flavonoid contents. The control groups indicated that Korean conventional seed ginger had 1.0-1.3 times higher gingerol contents compared to Chinese seed ginger. Furthermore, the content of shogaols, considered major functional ingredients, increased significantly with longer steaming durations, reaching the highest content (1,793 mg/kg) at 8 h, which was 1.0-1.8 times higher in Korean conventional seed ginger than that in Chinese seed ginger. These experiments provide valuable data supporting the excellence of Korean conventional seed ginger in the future.
