방사성핵종의 특성, 섭취형태 그리고 내부피폭 감시주기는 작업자의 방사성핵종 섭취량 및 내부피폭선량 평가 결과에 중요한 영향을 줄 수 있다. 따라서 방사성핵종이 흡입섭취 될 경우 섭취형태(급성 또는 만성) 및 내부피폭 감시주기에 따른 섭취량 평가 오차를 계산하였다. 섭취 핵종으로는 /I(Type F), Cs(Type F), U(Type M, Type S)를 고려하였고, 방사능입자크기(AMAD)는 1 와 5 를 고려하였다. 섭취형태에 따라 평가된 섭취량의 상대오차는 방사성핵종, 흡수형태 그리고 내부피폭 감시주기에 따라 달랐으나, 입자크기에 의한 영향은 거의 없었다. 섭취형태 가정에 따른 섭취량 평가 오차를 10% 미만으로 줄일 수 있는 내부피폭 최대감시주기는 /I(Type F)에 대해 60일, Cs(Type F)에 대해 180일, U(Type M)에 대해 90일, 그리고 U(Type S)에 대해 360일로 나타났다.

Lipoxygenase is responsible for the beany flavor and soybean kunitz trypsin inhibitor protein is responsible for the inferior nutritional quality of unheated or incompletely heated soybean meal. Anthocyanins from black soybean seed coat are known to have many pharmaceutical effect. The object of this study is to select black soybean genotype with absence of lipoxygenase-2,3 (Lx1Lx1lx2lx2lx3lx3) and small seed size. Two cultivars (“Seomoktae” and "Gaechuck#1") were used. "Seomoktae" cultivar has the traits of small seed size, black seed coat, green cotyledon and lipoxygenase protein. "Gaechuck#1" has the traits of big seed size, black seed coat, green cotyledon and lipoxygenase free protein. In the F2 population, the several plants with small seed size and lipoxygenase free protein were selected. In F3 and F4 generation, seed size and lipoxygenase protein was comfirmed from the bulked seed harvested at field. The F5 seeds with small seed size and Lx1Lx1lx2llx2lx3lx3 genotype were planted in the field. Several agronomic traits were evaluated. The lines with appropriate agronomic traits were selected.

The soybean cyst nematode (Heterodera glycines Inchinoe; SCN) is a devastating pest of soybean and is responsible for significant losses in yield. The use of resistant cultivars is the effective method to reduce or eliminate SCN damage. The objective of this research is to identify AFLP markers linked to the SCN resistant genes. Bulked genomic DNA was made from resistant and susceptible genotypes to SCN and a total of 19 primer combinations were used. About 31 fragments were detected per primer combination. The banding patterns were readily distinguished in resistant and susceptible bulked genotypes. Polymorphic fragments were detected between resistant and susceptible bulked genotypes in the primer combination of CGT/GGC, CAG/GTG and CTC/GAG. In primer combinations of CGT/GGC and CAG/GTG, bulked resistant genotype produced a polymorphic bands. However, in primer of CTC/GAG, bulked susceptible genotype produced a polymorphic fragments. Three AFLP markers identified as a polymorphic fragments between bulked genomic DNA were mapped in 85 F2 population. Among them, only two markers, CGT/GGC and CTC/GAG, was linked and was mapped. Broad application of AFLP marker would be possible for improving resistant cultivars to SCN.

Narcotic drugs generally refer to serious and habitual hidden rash such as opium, heroin, methyphetamin, nabinol, cocaine, and so forth. At present, narcotic drugs are spread unchecked and are causing a big social problem. So many countries and narcotists are making every effort to set up a barricade against narcotic drugs. And there is a limit suitable treatment for them. Thus Tuo Yin Tang Jiang is developed. As indicated by Chinese letters, Tuo Yin Tang Jiang(TYTJ) is a crude drug. It is a traditional chinese medicine developed by the study done from June in 1998 to June in 1999 that Hubeisheng was entrusted with by People's Republic of China. This study is a treatise on etiology and syntomatology of narcotism. TYTJ is a medicine which is in accord with Pharmacopeia of the People's Republic of Chinal) in order to remove from the body the toxic materials resulting from narcotic drugs such as opium and heroin. According to the standard diagnosis on narcotism, 105 cases are studied and treated at the Rehabilitation Center attached to Enshi Autonomous Region Hospital in Hubeisheng. 105 cases are divided into 2 groups by double-blind method. One is the experimental group which has 56 cases. The other is the control group which has 49 ones.13 cases among 105 cases are addicted by intravenously injections. 9 cases are by oral takings. It took 10 days for this experiment to be performed. Two groups didn't show a striking individual variation based on the age, gender, period of taking drugs, withdrawal symptoms, complication, and state of health. The experimental group had a higher effect of treatment than the control group had. TYTJ treats diseases effectively and has no side effect, irrespective of the serious or slight addiction to opium and morphine.

Soybean [Glycine max (L.) Merr.] seed weight is a important trait in cultivar development. Objective of this study was to identify and confirm quantitative trait loci (QTLs) for seed weight variation in the F2 and F2:3 generations. QTLs for seed weight were identified in F2 and F2:3 generations using interval mapping (MapMaker/QTL) and single-factor analysis of variance (ANOVA). In the F2 plant generation (i.e., F3 seed), three markers, OPL9a, OPM7a, and OPAC12 were significantly (P<0.01) associated with seed weight QTLs. In the F2:3 plant row generation (i.e., F4 seed), five markers, OPA9a, OPG19, OPL9b, OPP11, and Sat_085 were significantly (P<0.01) associated with seed weight QTLs. Two markers, OPL9a and OPL9b were significantly (P<0.05) associated with seed weight QTLs in both generations. Two QTLs on USDA soybean linkage group C1 and R were identified in both F2 and F2:3 generations using interval mapping. The linkage group C1 QTL explained 16% of the variation in seed weight in both generations, and the linkage group R QTL explained 39% and 41% of the variation for F2 and F2:3 generation, respectively. The linkage group C2 QTL identified in F2:3 generation explained 14.9% of variation. Linkage groups C1, C2 and R had previously been identified as harbouring seed size QTLs. The consistency of QTLs across generations and populations indicates that marker-assisted selection is possible in a soybean breeding program.

Molecular markers are useful to confirm the hybridity of F1 plant derived from cross of two homozygous parents with similar morphological traits. RAPD markers were used to test F1 hybrid plant obtained from cross of two homozygous soybean (Glycine max) parents. Fl plant for cross I was made from the mating of Hobbit87 (female) and L63-1889 (male) and Fl plant for cross II was obtained from the mating of H1053 (female) and L63-1889 (male). Selfing plant per each cross was also obtained. Among 20 Operon primers used, OPA04 and OPA09 show polymorphism between cross I and II parent. Band in size 1Kb of OPA04 and 2.1Kb of OPA09 primer was polymorphic band. This fragment identified Fl hybrid plant and selfing plant in cross I and II. Female parent Hobbit87 in cross I and H1053 in cross II has no this fragment (recessive allele). However, male parent L63-1889 and Fl hybrid plant in cross I and II has this size of polymorphic band (dominant allele). This indicated that Fl hybrid and selfing plants were detected by RAPD marker before phenotypic marker would be used to identify Fl hybridity. Amplification products of selfing plant for cross I and II were completely same to the those of female parent. When mature, flower color of Fl hybrid plant in cross I and II was purple and flower color of selfing plant in cross I and II was white. Purple flower is dominant trait. Fl hybridity was successfully detected at very early growth stage using RAPD marker. Therefore, RAPD marker can be used broadly to confirm Fl hybridity in many crops.
