This study was carried out to evaluate the possibility of citron seed as industrial resource by analyzing chemical properties and the antioxidant activity. Crude lipid content of citron seed was $35.29{\pm}0.18%$. Total mineral content in citron seed was 1171.64 mg/100g and the potassium content ($637.99{\pm}5.38mg/100g$) was the highest. The contents of total phenols and flavonoids in citrus seed were $24.44{\pm}1.10mg/100g$ and $2.27{\pm}0.18mg/100g$, respectively. The electron donating ability using DPPH, hydroxy radical scavenging activity and SOD-like activity were increased significantly by increased the sample concentration in the reaction mixture. The nitrite scavenging ability was dependent on pH of reaction mixture and sample concentration. It was higher activity at pH 1.2 than pH 4.2. During the storage of soybean oil, the peroxide and acid values of the oil were significantly increased regardless of addition of citron extract. But antioxidant activity of soybean oil added with ethanol extract from citron seed was superior to that of control (sample with no addition) at 16 days of storage.

A new sprout-soybean cultivar, "Sohwang" was developed at the National Institute of Crop Science (NICS) in 2008. "Sohwang" was selected from a cross between Pungsan and Pungsan/Nattosan. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 58 were carried out from 2004 to 2008. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, yellow seed coat, Yellow hilum, lanceolate leaflet shape and small seed size (8.5 grams per 100 seeds). The maturity date of "Sohwang" is 10 days earlier than the check variety, "Pungsan". It has a good seed quality for soybean-sprout. The soybean-sprouts grown from "Sohwang" have high isoflavone ($3,041{\mu}g/g$)contents. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N), and other most troublesome soybean diseases which are bacterial pustule and black root rot. Especially, "Sohwang" has useful characteristics, such as lodging and shattering resistance. The average yield of "Sohwang" was 2.69 ton per hectare in the carried out for three years from 2006 to 2008 regional yield trials(RYT) for double cropping.

The drum-type hill-drop unit, an important working device of the plastic -film-covered hill planter, can finish filling and separating seed precisely, perforating film and holing , and its seeding depth and spacing are stability . The unit is applied to hole seed many crops, for example, cotton, corn , soybean, etc. The drum-type hill-drop unit(DHU) , the key work unit to the plastic film-covered planter, mainly consists of distributor box , seeding parts, hole forming unit and drum , It can be operated to accomplish seeds distributing, hole forming , plastic film perforating . Moreover , its inner cavity can be used as seed box.

There is much evidence suggesting that compounds present in soybean can prevent cancer in many different organ systems. Especially, soybean is one of the most important source of dietary saponins, which have been considered as possible anticarcinogens to inhibit tumor development and major active components contributing to the cholesterol-towering effect. Also they were reported to inhibit of the infectivity of the AIDS virus (HIV) and the Epstein-Barr virus. The biological activity of saponins depend on their specific chemical structures. Various types of triterpenoid saponins are present in soy-bean seeds. Among them, group B soyasaponis were found as the primary soyasaponins present in soybean, and th e 2, 3-dihydro-2, 5-dihydroxy-6- methyl-4H-pyran-4-one(DDMP)-conjugated soyasaponin $\alpha\textrm{g}$, $\beta\textrm{g}$, and $\beta$ a were the genuine group B saponins, which have health benefits. On the other hand, group A saponins are responsible for the undesirable bitter and astringent taste in soybean. The variation of saponin composition in soybean seeds is explained by different combinations of 9 alleles of 4 gene loci that control the utilization of soyasapogenol glycosides as substrates. The mode of inheritance of saponin types is explained by a combination of co-dominant, dominant and recessive acting genes. The funtion of theses genes is variety-specific and organ specific. Therefore distribution of various saponins types was different according to seed tissues. Soyasaponin $\beta\textrm{g}$ was detected in both parts whereas $\alpha\textrm{g}$ and $\beta$ a was detected only in hypocotyls and cotyledons, respectively. Soyasaponins ${\gamma}$g and $\gamma\textrm{g}$ were minor saponin constituents in soybean. In case group A saponins were mostly detected in hypocotyls. Also, the total soyasaponin contents varied among different soy-bean varieties and concentrations in the cultivated soy-beans were 2-fold lower than in the wild soybeans. But the contents of soyasaponin were not so influenced by environmental effects. The composition and concentration of soyasaponins were different among the soy products (soybean flour, soycurd, tempeh, soymilk, etc.) depending on the processing conditions.
