최근에 개정된 중 저준위 방사성폐기물 인도규정에서는 폐기물시설운영자는 처분 전 방사성폐기물이 인도규정에 적합함을 보장하기 위한 계획을 수립하여 운영할 것을 요구하고 있다. 앞으로 건설될 방사성폐기물 처분시설에서 방사성폐기물 인수 시에 충족되어야할 방사성폐기물인수기준이 수립될 것이며, 이 인수기준에는 물리화학적 및 방사선학적 특성규명, 물리화학적인 제한사항, 금지품목, 포장, 인식표, 라벨, 문서요건 등을 규정할 것으로 예상된다. 이들 규정을 준수하기 위하여 방사성폐기물 발생자는 방사성폐기물이 폐기물 인수기준에 만족하는지를 확인하는 폐기물 인증프로그램을 수행하여 방사성폐기물이 그 기준에 만족하는지 확인하여야 하며, 방사성폐기물에 대한 모든 인증서류를 폐기물 처분시설에 제출할 책임이 있다. 본 방사성폐기물 인증프로그램계획은 한국원자력연구소에서 발생되는 방사성폐기물의 인증프로그램에 대한 예비프로그램으로서 개발된 것이며 앞으로 처분장의 인수요건이 구체적으로 확립될 때까지 수정 보완되어야 한다.

원자력을 이용하는 시설 및 그와 관련한 연구개발실험실로부터 각종 화학폐수가 다량으로 발생되고 있으며 이들 폐수를 화학폐수 전용처리시설로 처리하고 있으나 최종 건조 케이크내에 함유된 우라늄의 농도가 규제면제농도인 10 Bq/g을 약간 초과하므로서 방사성폐기물로 분류하여 별도로 저장하고 있다. 화학폐수 처리후 침전된 슬러지내의 우라늄 농도를 분석한 결과 우라늄이 용액상이 아닌 침전물상에 존재함을 알았으며, 이들 우라늄을 침전물로부터 용액상으로 용해하기 위하여 강질산으로 용해시켰다. 그 결과 대부분의 우라늄이 슬러지의 침전물로부터 용액상으로 용출되었으며, 용해후 얻어진 슬러지 산용해액에 대해 IRN-77과 비드형으로 새로 제조한 다이포실 수지를 실 폐액처리에 적용하기 위한 흡착실험을 수행하였다. IRN-77과 다이포실 비드를 단독, 혼합 또는 단계적으로 사용한 결과, 80%이상의 우라늄 흡착효율을 얻기 위해서는 산용해액과 동등량 또는 그 이상의 다량의 수지가 소요되었다. 한편 침전 슬러지를 압착하여 부피가 더욱 축소된 탈수케이크를 산용해한 결과, 탈수케이크 대 질산의 비율이 3:2에서 우라늄의 함량을 최대 11 mg/L을 얻었으며 슬러지 용해시보다 적은 양으로 산용해가 가능하였다. 탈수 케이크 산용해액의 방사능 농도는 6.97E-01 Bq/ml 로서 기존의 자연증발처리시설에서 처리가 가능한 수준이었으며, 건조케이크의 비방사능은 11.2 Bq/g로서 최종 폐기물로 발생될 폐증발천의 비방사능이 4.3 Bq/g으로 평가되어 우라늄 동위원소의 규제면제치인 10 Bq/g 미만이므로 자체처분이 가능한 수준이었다. 결론적으로 화학폐수를 처리한 후 부피가 최소화된 탈수케이크에서 우라늄을 산용해시키고 최종 산용해액은 기존의 자연증발시설로 증발처리하면 방사성 건조케이크의 발생 없이 또한 자연증발천도 자체처분이 가능한 최적의 방안을 도출하였다.

Anthocyanin in blackish purple rice is composed of cyanidin, peonidin, malvidin, pelargonidin and delphinidin flavylium ion and their glucosides, which shows antioxidant activity similar to a-tocoperol. It has been demonstrated that cyanidin-3-glucoside(C3G) of anthocyanin has a high-potency antioxidant activity, and is a prominent in anticancer and antithrombotic activity. In analysis of content of anthocyanin from the genetic source of blackish purple rice, the level of C3G was approximately 80% of total contents of anthocyanins, and showed the highest content in Heugjinjubyeo, of which contains an amount of 500 mg by weight of 100g brown rice in comparison that most of varieties has less than 50mg by weight of 100g brown rice. We found that C3G pigment in blackish purple rice was considerably affected by cultural season, cultivation area, ripening temperature, and weather condition, etc. as well as genetic properties. In cross combination between Heugjinjubyeo and Suwon425, intermediate parent F9 generation which was three times higher or more in C3G content than that of Heugjinjubyeo was bred, of which it contained an amount of 1678 mg by weight of 100g brown rice, and we called it 'C3GHi' Rice. And, we found that the C3GHi rice was more excellent than that of the existing Heugjinjubyeo in anticancer and antithrombotic activity. Methanol extract from Heugjinjubyeo was fractionated by organic solvents in order of n-hexane, CH2Cl2 and n-BuOH, and then oryzafuran, quercetin, vanillic acid and protocatechuic acid and their structures from the n-BuOH fraction were ascertained. Oryzafuran of these compounds was a natural compound found firstly in nature. Quercetin and protocatechuic acid besides new compound oryzafuran showed excellent antioxidant ability to vitamin C. These results suggest that blackish purple rice has very high value as a source of various functional food as well as staple food.

해체비용 산정은 원자력시설에 대한 해체 설계 및 계획 수립하는 데 중요한 기술이다. 해체비용 산정은 해체활동 단계와 해체시설의 구성요소에 맞게 해체작업을 분류하여 계산을 해야 한다. 본 논문에서는 원자력연구시설 해체비용 산정 기술로 이용하기 위하여 해체비용항목 및 그룹의 구성요소와 해체대상물에 대한 작업시간 계산의 기준이 되는 단위비용 인자 구성요소를 도출함으로써 해체비용 산정에 필요한 기본 구조를 완성하였다. 또한 주요 해체활동 및 작업에 대한 비용 산정 시 구성요소에 대한 고려사항을 살펴보았다. 향후, 이러한 기법을 이용하여 원자력연구시설에 대한 해체비용 산정 및 평가 방법론을 확립하는데 기본 기술로 활용할 예정이다.

Leaflet number of soybean controlled by Lf2 locus is the important trait in photosynthesis and plant type. The objective of this research was to identity molecular markers linked to the lf2 locus. A total of 115F2 plants were derived from a cross between normal three-leaflet type Sinpaldalkong (Lf2Lf2) and seven-leaflet mutant type T255 (lf2lf2). All leaflet counts of parents and F2 individual plants were made in the field on fully expanded leaves on the main stem when terminal growth of the main stem had ceased. One-thousand 10-mer oligonucleotide RAPD primers and 664 SSR primers were used. The segregation ratios of 3 : 1 were observed in the F2 population and the Chi-square values strongly suggested that the seven-leaflet was controlled by a single recessive gene. A genetic map was constructed from the 15 segregating markers (9 RAPDs, 5 SSRs, 1 lf2 locus). OPAD03 and OPAI13 RAPD markers were linked to the lf2 locus that controlled seven-leaflet type at a distance of 20.5 and 23.5 cM, respectively. Molecular markers identified in this study linked with lf2 locus will be helpful to locate lf2 locus on the public soybean molecular linkage map and would be useful for tagging the lf2 locus that controls seven-leaflet trait.
