The government of Gyeongbuk in Korea increased the financial input in the agricultural sector by 43% from 2008 through 2012. However, the productivity of the agricultural sector in Gyeongbuk rose only about 3.6% during the same period. This study evaluated the agricultural competitiveness of each city or county in Gyeongbuk using six evaluation indices (scale, productivity, finance input, location quotient, technical education, and total) and investigated the relationship between the indices and total values of agricultural productions. The results show that Sangju, Gyeongju, Andong, Uiseong, and Seongju have high competitiveness for the scale index. For the productivity index, Gimcheon, Mungyeong, Ulleung, Yeongju, and Seongju were highly evaluated. For the location quotient index, Yeongcheon, Uiseong, Cheongdo, Seongju, and Sangju have high competitiveness. Uiseong, Yeongdeok, Cheongsong, Gunwi, and Yeongyang were highly evaluated for the agricultural finance input index. For the agricultural technical education index, Chilgok, Sangju, Mungyeong, Uiseong, and Gyeongju have high competitiveness. Finally, Sangju, Euiseong, Yeongcheon, Gyeongju, and Andong were highly evaluated for the total competitive index, while Yeongdeok, Yeongyang, Goryeong, Uljin, and Cheongsong have a low competitiveness for the total competitive index. This study also found that out of five indices, scale, location quotient, and technical education indices have a positive and statistically significant effect on the total values of agricultural production. However, we did not find any statistically significant effect of the productivity and finance input indices on the total values of agricultural production. Hence, we can conclude that the government should focus their agricultural policy on scale, location quotient and education to improve total agricultural production.

Also, 2,3,7,8-T4CDF is not detected in soil on Yeungju and Sangju. PCDDs and PCDFs in Yeungju soil are 1.957 pg/g and 0.294 pg/g, respectively. Total of dioxins in Yeungju soil are 2.251 pg/g. PCDDs and PCDFs in Sangju soil are 1.220 pg/g and 0.420 pg/g, respectively. Total of dioxins in Sangju soil are 1.640 pg/g. PCDDs and PCDFs in Yeungju soil are 0.0049 pg WHO-TEQ/g and 0.0123 pg WHO-TEQ/g, respectively. Total of dioxins with PCDDs and PCDFs in Yeungju soil are 0.0172 pg WHO-TEQ/g. PCDDs and PCDFs in Sangju soil are 0.0065 pg WHO-TEQ/g and 0.0213 pg WHO-TEQ/g, respectively. Total of dioxins with PCDDs and PCDFs in Sangju soil are 0.0278 pg WHO-TEQ/g. Amount for pg/g concentration unit of PCDDs is higher than amount of PCDFs in soil. But, WHO-TEQ of PCDFs is higher than WHO-TEQ of PCDDs in soil.

뽕나무 열매(오디)를 이용하여 천연항산화제를 개발할 목적으로 오디로부터 페놀성 물질을 추출하여 항산화 활성을 측정하였다. 페놀성 물질의 추출은 60$\%$ ethanol을 사용하여추출하는 것이 수율이 가장 좋았으며, rutin과 isoquercetrin의함량이 높았다. 추출된 오디 추출물의 ABTS radical decolorization과 antioxidant protection factor(PF)를 살펴 본 결과 ABTS는 80 추출물이 약 98$\%$의 억제율로 최고의 저해율을 나타내었고, PF는 60$\%$ 추출물에서 1.25로 가장 높은 protection factor를 나타내었다. DPPH에 대한 전자공여능은 60$\%$ 에탄올 추출물이 물 추출물이나 다른 농도의 ethanol추출물의 전자공여능 보다 우수하였다. 활성산소 중 지방산화를 일으키는데 주요한 역할을 하는 hydroxyl radical에 대한 각 추출물들의 영향은 60$\%$ 에탄을 추출물이 다른 추출물에 비하여낮은 TBARS 값을 나타내었다. 이상의 결과로 볼 때 오디로부터 추출한 페놀성 물질은 천연 항산화 물질로 활용할 수있을 것으로 생각되었다.

Three year-old peony (Paeonia. lactiflora Pall. cv. Taebaek) was cultivated in green-house at Jan. 15, Feb. 15, or Mar. 15, respectively. The mean of temperature during the forcing cultivation was higher (air; $1.0{\sim}11.1^{\circ}C$, soil; $1.1{\sim}7.4^{\circ}C$) than that of open-field condition. From sprouting to flowering in peony cultivated at Jan. 15 was about 54 days, which is shorted the cut flower periods (ca. 26 days) compared with the open-field cultivation. However, earlier forcing cultivars were very susceptible to pathogens such as powdery mildew or gray mold. The yield in green house was also lower than in the open-field cultivation. The content of bioactive compounds such as paeoniflorin and albiflorin in green-house cultivars was similar that of open-field cultivars. These results showed the forcing cultivation time of peony at Feb. 15 in green-house was most desirable for commercialization.
