The purpose of this study was 1) to find out the dimensions of consumers motive of variety seeking and variety seeking behavior toward clothing products, 2) to examine the relationship between above variables, and 3) to classify consumer group according to their motive and behavior of variety seeking, and to compare the groups characteristics in terms of the fashion interests and clothing purchase behavior. The data were obtained from 913 female university students, career women, and housewives using questionnaire. Consumers appeared to have the motive of variety seeking in clothing products, and the motive was composed of four factors. Consumers would show variety seeking behavior in clothing products. And the behavior was composed of three factors. Positive relationship existed between the motive and the behavior of variety seeking, while, the 4 factors of variety motive influenced differently on the different factors of variety seeking behavior. Subjects were classified into four groups according to their motive of variety seeking and variety seeking behavior. A significant differences were found among the 4 groups in fashion interests as well as quantity of purchase, frequency of purchase to clothing products.

The objective of this study was to know prospect and present state of new variety breeding of Forage and Grassland in South Korea. The industry of forage in Korea is going up to expend through utilization of good quality forage, Italian ryegrass, forage corn and oat rather than rice straw. Especially, since 2007, Italian ryegrass(IRG) had been very important major winter forage crop in South Korea and developed 13 varieties including very early maturity variety (three varieties), early maturity variety (three varieties), medium maturity variety (one variety) and late maturity variety (six varieties). But the disadvantage of Italian ryegrass was weak winter hardness and drought but has good advantage of forage nutritive value, high-yielding and high sugar content, and like livestock as like hanwoo, dairy cattle, goat so on. The Ko-variety (Korea developed variety) of Italian ryegrass has high cold-tolerant and adaptability more than any other country developed variety, and expend to cultivation area from southern area (below Daejeon) to middle-northern area (upper Han river). Although the cultivation area of Italian ryegrass of South Korea was 21,700 ha in 2007, right now, that of Italian ryegrass is about 123,600ha due to expend cultivation area and know famer to good forage crop and have a various maturity varieties (very early, early, medium, late) according to local situation (before-crop harvesting stage or double cropping system). The seed market of Italian ryegrass in South Korea becoming extended to around 100 million Korean won and seed export get nearer to foreign country. We are going to develop of new variety for stress tolerant and high yield and quality forage variety, good adaptability to the Korean environmental conditions including reclaimed area, make self-sufficiency system for forage seed (Italian ryegrass), export our seed to foreign countries.

Selection of oat variety according to cultivation period is an important to increase productivity of forage crop. To investigate the growth characters and dry matter productivity of oats according to cultivation period, early-maturing oat(EM0) and medium-maturing oat(MM0) variety were sown in spring and autumn at central district of Korea. When oats were cultivated in spring, MMO variety was longer 8 cm in leaf length and wider 5 mm in leaf width than 25 cm and 12 mm of EM0 variety, rexpectively. but in autumn, those were not different between maturities of oat varieties. Plant length of MMO variety was longer 7 cm than that of EM0 Variety in spring cultivation, but in autumn, plant length of EM0 variety was longer 14 cm than that of MMO variety. Heading dates were 20th to 22th May in EM0 variety, and 30th May to 10th June in MMO variety in spring cultivation, and ear of EM0 variety emerged 30th Oct. to loth Nov. but that of MMO variety did not emerge at harvesting day in autumn cultivation. In Spring cultivation, dry matter(DM) yield of EM0 variety was 7,349 kg/ha that was less 56% than 11,466 kg/ha of MMO variety, but In Autumn, was more 15% than 6,575 kg/ha of MMO variety. In conclusion, selection of oat variety in spring and autumn cultivation can be different with cropping system of forage crop, and this trial is suggesting that oat variety could be sown MMO variety in spring and EM0 variety in autumn at central district of Korea.

The structure and properties of silk polymers (fibroin and sericin) can be satisfactorily controlled by choosing a suitable silkworm variety and, hence, this parameter (i.e., silkworm variety) has attracted increasing attention. A previous study reported that the crystallinity of white colored silkworm cocoons depends on the silkworm variety. In the present study, sixteen yellow colored silkworm variety cocoons were produced and their molecular conformation and crystallinity were investigated. The conformation of the silkworm cocoons varied with the silkworm variety. Most cocoons exhibited ${\beta}$-sheet conformation, although random coil and ${\beta}$-sheet conformations co-existed in some cocoons (e.g., 21 and D90). The crystallinity of the silkworm cocoons varied with the silkworm variety and the measurement position of the cocoon (i.e., outer surface or inner surface). However, the difference in the crystallinity indices of the outer and inner surfaces comprising the cocoons varied with the silkworm variety, but was <2% for all cocoons, except for MAL.

국내 화훼류 육성품종의 미국 출원에 대한 안내 및 미국 육성 품종의 국내 출원 시 품종보호심사에 활용하는 자료로 제공하고자 미국의 식물신품종보호제도와 식물특허에 대한 운영실태를 조사하였다. 미국은 신품종 대상에 따라 종자번식 품종과 괴경식물은 식물신품종보호법으로, 무성번식품종은 식물특허로 구별되어 보호를 받게 된다. 품종보호나 특허를 받기위한 조건은 신규성, 구별성, 균일성, 안정성이며, 과수나 묘목의 품종보호 보호기간은 25년이고 나머지 대상의 품종보호와 식물특허의 보호기간은 20년이다. 식물신품종보호와 식물특허의 심사 모두 재배심사나 현지심사를 하지 않고 출원인이 제출한 서류만으로 심사를 한다. 화훼류 출원은 영양체번식 품종의 식물특허 출원이 대부분이고 종자번식 품종의 품종보호 비율은 낮으며, 전체 식물특허 출원 중 화훼류가 87%를 차지하며, 자국과 외국간 출원 품종수에는 큰 차이가 없다.
