Phylloides tumor is very similar to giant fibroadenoma in that they have benign appearance in breast radiologic image. Fibroadenoma has no malignant potential, but phylloides tumor is locally recurrent, invasive and may occasionally metastasize. It thus appears that evaluation of the differential point of the two tumor groups by radiologic study is very important. We retrospectively compared sonographic findings of 6 cases of phylloides tumor with those of 4 cases of fibroadenoma, which proved pathologically in Yeungnam University Hospital from 1984 to 1986. The mean age of the patients were 31.8 years old(from 14 to 41 years old) in phylloides tumor and 28.8 years old (from 17 to 40 years old) in giant fibroadenoma, respectively. The viewpoints of this analysis were size, shape and contour of the masses, internal echo pattern, posterior enhancement, and especially the existence of peripheral cyst or septal band echo. We found that diffenentiation of these two tumors by sonography was difficult. But peripheral cyst was found only in phylloides tumor and septal band echo was found largely in giant fibroadenoma. Although the existence of peripheral cyst or septal band echo in the breast mass was not pathognomonic findings, we suggest that the existence of septal band echo is preferential finding to fibroadenoma, and peripheral cyst is preferential finding to phylloides tumor.

This study was conducted to estimation the selection response for growth-related traits in 31-month old of Pacific abalone, Haliotis discus hannai were born in 2008. In overall mean of surveyed traits and standard deviation showed $76.31{\pm}7.247$ mm of shell length, $49.48{\pm}5.307$ mm of shell width and $40.96{\pm}6.80$ g of total weight. The effect of sex and maturity were statistically significant in all traits include out a condition factor (p < 0.01). And In effect of sex, female were higher than male in all traits excepting condition factor, significantly. In correlation between breeding value and phenotypic value by each traits, showed rank correlation coefficient and simple correlation coefficient, which represented low positive correlation. A hopeful genetic improvement to the next generation showed 6.96 mm of shell length, 4.47 mm of shel width and 12.93 g of total weight. Therefor, It is considered that if considering properly selection intensity and selection ratio, efficient improvement could be made.

We analyzed the mammographic (n=21) findings (location, margin, shape, cluster microcalcifications, size, multiplicity) and ultrasonographic (n=12) findings (shape, border, internal echo, boundary echo, posterior echo, lateral echo, width/depth ratio) to evaluate specific radiologic findings of histopathologically proved uncommon breast cancer. The mammographic findings (n=21) are as follow; 1) single; 16, multiple; 5 2) margin (smooth; 13, irregular; 4, spiculated; 4) 3) shape (round and ovoid; 9, lobulated; 8, irregular; 4) 4) cluster micro calcifications (abscent; 20, present; 1) 5) size (1-3cm; 18, 3-5cm; 2, 5cm> ; 1) 6) location (UOQ; 13, UIQ; 4, LIQ; 3, LOQ; 1). The ultrasonographic findings (n=12) are as follow; 1) shape (round to oval; 5, lobulated; 5, irregular; 2) 2) border (smooth even; 9, rough uneven; 3) 3) internal echo (fine homogeneous; 5, coarse heterogeneous; 7) 4) boundary echo (regular fine; 4, irregular thick; 8) 5) posterior echo (enhanced; 11, no change; 1) 6) lateral echo (marked; 7, nonexistent; 5) 7) width/depth ratio (1.5> ; 1, 1.0-1.5; 7, 1.0< ; 4). Uncommon breast cancer show benign nature on mammogram, but malignant nature on ultrasonogram (especially boundary echo, internal echo, width/depth ratio).

'Anyu', a perilla (Perilla frutescens (L.) Britton) cultivar for edible seed was developed by the Department of Functional Crop Science, National Institute of Crop Science, RDA in 2008. It was originated from the cross between a pedigree of YCPL1824 as a female and SF9225-3-1 as a male parent in 1998. 'Anyu' can be characterized by purple flower color and brown grain color. 'Anyu' showed semi-dwarft type with 120 cm height, and has lodging tolerance. Maturing date of 'Anyu' was September 24, which is 15 days faster than that of 'Saeyeopsil'. The early maturity of this new cultivar showed a great advantage to various planting system with other crops. This new cultivar has high oil content (45%) and high linolenic acid in the fatty acid composition. The yield potential of 'Anyu' was about 0.9 ton/1ha in the regional yield trial.

About 250 bp ura5 gene (Orotate phosphoribosyl transferase) fragment was cloned from genomic DNA of entomopathogenic fungus Metarhizium anisopliae by using PCR method. Entire nucleotide sequences of cloned DNA fragment were determined and analysed as compared with other fungus ura5 genes. The amino acid sequence deduced from the nucleotide sequence showed 85.5% homology to ura5 protein of Trichoderma reesei. Using this 250 bp PCR fragment we have isolated full ura5 gene of M. anisopliae by genomic Southern hybridization and the isolated 4.4 kb DNA fragments were mapped by restrictional enzyme.

A new peanut variety "Pungan"(Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Functional Crop, NICS(National Institute of Crop Science), in Milyang in 2008. It was developed from the cross between the high-yielding cultivar "Saedl" and the very short stem cultivar "Satonoka". "Pungan", a Virginia palnt type, has 20 branches with long ellipseshaped large grains. The 100 grain weight was 88 g, 7 g heavier than the check variety Daekwang. This variety is more resistant to late leaf spot and web blotch compared to Daekwang, a check variety. Moreover, it is lodging resistant owing to its short stem. "Pungsan" outyielded the check variety by 16% with 4.67 MT/ha in regional yield trials.

A new peanut variety "Pungsan" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was derived from a cross between a short stem cultivar "Satonoka" and a high-yielding local cultivar "Yecheon". "Pungsan" is the Virginia plant type. It has 18 branches per plant and 40 cm of main stem height. Each pod with long-ellipse shaped large kernel has two grains with light-brown testa and 100 seed weight was 95g in the regional yield trials (RYT).

"Green King" is a new mini kiwifruit variety developed at the National Institute of Subtropical Agriculture (NISA), RDA in 2005, which was an edible fruit without peeling. This variety was selected from seeds obtained from the cross breeding between Actinidia chinensis cv. "Apple Sensation" and A. arguta in 1998. Seedling and line selections were conducted from 1999 to 2002, and characteristic trials were carried out from 2003 to 2004. The branch of "Green King" sprouts strongly and the color of leaf is slightly dark green. The shape of fruit is cylindric and the color of peel is green or yellowish green without hair. The average weight of fruit is 15.9 g. The core is small and soft, the pericarp is light green. Soluble solids concentration is $15.4^{\circ}Brix$. The fruit is sweet with slightly acid taste, containing total acid 1.3%, and the yield is higher over twice than that of A. arguta. The content of vitamin C is higher than that of A. arguta. The harvesting time is from middle October. This variety can be planted in the central and southern region of Korea.
