Rhubarb is the well-known and frequently used herbal medicine for the treatment of constipation, inflammation, and cancer. As described in the Korea and Chinese Pharmacopoeia, rhubarb consists of the roots and rhizomes of Rheum palmatum, R. officinale, and R. tanguticum. However, the pharmacological differences among rhubarb have not been scientifically established. In the present study, we investigated and compared the inhibitory effects of 70% ethanolic extracts from R. palmatum (RPE), R. officinale (ROE), R. nobile (RNE), and R. franzenbachii (RFE) on the production of inflammatory mediators, nitric oxide (NO), prostaglandin E2 (PGE2), interlukin-1beta (IL-1β), and tumor necrosis factor-alpha (TNF-α) in RAW 264.7 macrophage cells. ROE, RNE, and RFE significantly inhibited the release of NO, PGE2, IL-1β, and TNF-α. RPE significantly reduced the release of IL-1β, but not NO, PGE2, and TNF-α. Overall, RFE was found to inhibit the release of PGE2 and IL-1β, to a far greater degree than RPE, ROE, and RNE. Our results indicate that RFE possess the strongest anti-inflammatory activity among 4 tested rhubarb.

시마네현 다케시마문제연구회에서 나온 다케시마문제에 관한 조 사연구 최종보고서(2007.3)와 일본 외무성의 ｢竹島 다케시마 문제를 이해하기 위한 10가지 포인트｣(2008.3.8) 팸플릿의 경우 독도영 유권에 대해 ‘17세기 고유영토설’을 내세우고 있다. 본고는 이에 대한 비판을 제기하기 위해 공도정책이란 용어 대신에 수토정책이란 용어를 사용하자는 주장과 함께 일본의 17세기 고유영토설을 불식하기 위해 향후 수토정책에서 어떤 논리를 보강해야 할 것인가를 살펴 보고자 한 것이다. 일본의 17세기 고유영토설을 주장하는 울릉도로 건너갈 때의 정박 장이나 어채지로 이용하여 늦어도 17세기 중엽에는 독도의 영유 권을 확립했고, 17세기말 울릉도 도항을 금지했지만, 독도 도항은 금지하지 않았다고 한다. 그런 주장이 성립되기 위해서는 한일 양쪽의 자료에서 일본 어부들이 전적으로 독도를 목표로 하여 어로활동을 했다는 자료를 제시하지 않으면 안된다. 독도에서의 어 로활동은 울릉도를 근거지로 하여 이루어졌다. 일본 어부들은‘독도’만을 대상으로 해서 항해하지 않았다. 안용복 사건이후 울릉도와 독도에 들어온 사람들은 국제법 위반자들이었다. 그들은 1883 년 개척령에 의해 일본으로 소개되었다. 임진왜란 이후 1882년 이전까지 조선인들이 울릉도에 들어가 살았고, 그것을 거점으로 하여 독도에까지 어로활동을 하였음을 입증하는 자료를 발굴하여야 한다. 수토정책의 경우 일본으로 하여금 울릉도·독도가 우리 땅임을 인식시키고자 하는 정책을 부각시켜야 하고, 그것을 공도정책이라고 해서는 안된다. 또 수토정책 의 대상에는 울릉도 뿐만 아니라 독도도 포함되었음을 드러내주어야만 한다. 지금까지의 자료 가운데 울릉도에서 독도를 보았다는 자료는 제시되고 있지만 독도에 들어가 어로활동을 한 자료, 그리고 수토관이 독도를 심찰한 자료는 아직 발굴하지 못하고 있다. 이에 관한 자료 발굴에 초점을 두어야만 한다.

　A new kidney bean cultivar, “wanghyeob 2”was developed for edible pod kidney bean adaptable to Korean cultivation at the National Institute of Crop Science in 2005. “wanghyeob 2”was selected from a cross between KLG50073 and KLG50072. It has determinate growth habit, white flower, yellow pod color, oval shape of crossed section of pod at the harvesting time for edible pod. It has white seed coat and middle seed size (20.4 grams per 100 seeds). The average yield of edible pod of “wanghyeob 2”was 22.43 M/T per hectare in the yield trials which was carried out at the green house in spring and autumn in 2005. This yield level was 11 percent higher than that of the check cultivar “angnangkong 1”

A new kidney bean cultivar, “wanghyeob 1”was developed at the National Institute of Crop Science in 2005. “wanghyeob 1”was selected from a cross between KLG50064 and KLG50073. It has determinate growth habit, white flower, yellow pod color, oval shape of crossed section of pod at the harvesting time for edible pod, white seed coat and middle seed size (21.7 grams per 100 seeds). The average yield of edible pod of “wanghyeob 1”was 23.55 M/T per hectare in the yield trials which was carried out at the green house in spring and autumn in 2005. This yield level was 4 percent higher than that of the check cultivar “angnangkong 1”

‘oamibyeo’ a mid-late maturing ecotype with high amylose content in kernels, was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station(NYAES) in 2000 and released in 2001. This variety was derived from the three way cross of Milyang 95//Kimcheonaengmi/2*Ilpumbyeo (in 1992 summer) through the pedigree breeding method and designated as ‘ilyang 168’in 1997. The heading date of ‘oamibyeo’was Aug. 18 in ordinary season with culm length of 85 cm. However, ‘oamibyeo’showed susceptible to bacterial leaf blight, stripe virus and leaf blast disease. The amylose content of ‘oamibyeo’in milled rice kernels is about 26.7% with translucent and clear in chalkness. Thus, ‘oamibyeo’is expected to be used as a source grain for rice noodle industries. The milled rice yield potential of ‘oamibyeo’is about 5.38 MT/ha in local adaptability test of three years and it would be adaptable to Yeongnam plain of Korea.

Consumer"s concerns over beef safety are increasing according to resuming U. S. beef import And a few beef producers have converted into organic beef recently. This organic beef must have taste, nutrition and safety that consumers dem and for. Korean organic beef should be gone on sale at the shop under direct management of producer"s organizations or the special shop for Environmentally friendly products. So they should win consumers" confidence for beef safety and transparency in producing and marketing process.

Poncirus trifoliata Rafinesque has been used as the immature fruit of the trifoliate orange tree. This study was carried out to investigate the quality change of Poncirus trifoliata Rafinesque depending on packing materials (vacuum packing, PP (polypropylene) packing, gunny sack packing), storage places and storage periods up to 12 months. The change of loss on drying content, content of poncirin were measured during the 12 months. As a result, the loss on drying content was decreased rapidly in gunny sack packing after storage of 12 months at room temperature. The content of poncirin was decreased generally according to storage conditions and its average loss percent was 38.8%.
