This study was carried out to investigated the actual state of rice milling at local milling plants and to find out sources for elevating their milling recoveries in both quantity and quality. At 36 local milling plants located in Gyeongnam and Jeonnam , milling recoveries and head rice recoveries were measured with respect to their different milling systems and rice varieties. Then, the same samples of rice were milled by experimental milling equipments at laboratory, and the two experimental results were compared in order to determine the amount of milling recovery possibly to be increased. The results of this study are as follows ; 1. Milling recoveries of rice at local milling plants were proved to have no relationship with milling systems, and were 68.1% per ent and 72.6percent on an average with new variety and native variety, respectively. 2. The milling recoveries above stated can be elevated 4.5 percent and 2.9percent with new variety and native variety, respectively, by developing and extending technologies of manufacturing and handling rice milling machinery. 3. The head rice recovery of new variety at local milling plants has insignificant differences among milling systems, and was 54.8 percent on the average. With native variety, the recovery by friction type rice polisher was 0.9percent higher than that of friction-abrasive type polisher, and was 64.9 percent on the average. 4. The head rice recoveries of new variety and native can be elevated 5.1percent and 3.9percent, respectively, by the same stimulation above mentioned.

The purpose of this study was to establish the marketing strategy, that strengthens the brand royalty of their own in apparel industry and that can induce consumers brand switching against competitive brand. This study was classified into theoretical and experimental study. Experimental study was done, using the survey, to prove the models for consumers responses to brand switching by the theoretical study. It analyzed at last five hundred ninety-two women in the age of twenty to thirty years old who live in Seoul. Followings are the summary of the results revealed through the experimental study. First, brand switching behavior of consumers for formal dress was attributed to two extremes the inner motivation of variety seeking tendency and communication contact, complex variety seeking group, true variety seeking group, derived variety seeking group, and variety avoiding group. Second, the cognition response to marketing communication the types of brand switching shows difference in all communication variables except the service promotion of sales promotion communication. As to attitude response, it was found meaning difference in all communication variables except the sales promotion through price adjustment.

일반계 품종인 추청과 상풍, 다수계 품종인 태백과 용주를 시료로 하여 전기밥솥과 압력솥으로 취반한 쌀밥의 관능적 특성과 지질함량을 조사하였다. 전체적인 선호도는 압력솥으로 취반한 경우가 전기밥솥의 경우보다 좋았으며, 전기밥솥으로 취반한 경우, 일반계 품종이 다수계 품종보다 우수하였다. 취반 후 쌀의 유리지질 함량은 감소했고 결합지질 함량은 증가했다. 결합지질은 쌀밥의 윤기와 r=-0.69의 상관관계를 나타내었다.

Customer satisfaction level is usually measured in terms of price, qualify, customization, after-sale-service, product variety etc. Each firm sets up a distinctive production/marketing strategy to gain competitive advantage by Prioritizing the customer satisfaction measures. The market differentiation strategy directly results in supply chain performance such as lead time, inventory, customer fill rate and market share. Product proliferation desirable in customization sense often conflicts the economies of scale effect in production side. This paper focuses the relationship between product variety and market share. Specifically, we investigate how introduction of new product affects the current market share, i.e., formation of customer preference and provide some insight into the optimal range of product variety.

This study was carried out to assess the potential of SSR markers for variety identification by comparing SSR markers and morphological traits in tests of distinctiveness, uniformity, and stability (DUS) of pepper (Capsicum annuum L.) varieties. Twenty-seven SSR markers were polymorphic in 66 pepper varieties, revealing a total of 89 alleles. Average polymorphism information content (PIC) value was 0.529, ranging from 0.03 to 0.877. Cluster analysis of the band patterns separated the varieties into three groups corresponding to varietal types. Morphological trait-based clustering showed some degree of similarity to dendrogram topologies based on the SSR index. However, no significance correlation was found between the SSR and morphological data. SSR markers could be used to complement a DUS test of a candidate variety and to select complimentary varieties by pre-screening existing varieties in the context of protecting new varieties of pepper.

"Hwasan 103" is a new cold-tolerant Italian ryegrass(Lo1ium multiflorum L.) variety developed by theNational Livestock Research Institute(NLR1) in 1999. To develop a cold-tolerant variety of Italianryegrass(Lo1ium multiflorum L.), cold-tolerant clones survived under - 13 - - 14$^{\circ}$C of minimum average airtemperature(MAAT) in January were selected at Hwachun, Kwangwon Province in 1995. Five clones ofselected clones were polycrossed for seed production by NLRI, RDA in 1996."Hwasan 103" was diploid variety, green in leaf color and broad in flag leaf width. Also it hassemi-prostrate and medium growth habit in late autumn and in early spring, respectively. "Hwasan 103" wasexcellent in lodging tolerance at harvesting time. First heading date of "Hwasan 103" was 14th May, it wassimilar to that of Marshall. Expecially, "Hwasan 103" survived about 50-70% under - 10- - 12'C ofMAAT in January, so it could be cold-tolerant variety that can be safely cultivated in regions higher than -9$^{\circ}$C of MAAT in January. Compared with Marshall "Hwasan 103" showed 3% higher fresh yield (57.8MTper ha) and it showed 2% higher dry matter yield (11.OMT per ha). Higher IVDMD and TDN and lowerADF and NDF were observed in "Hwasan 103" than those of Florida 80 and Marshall in Forage quality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 103")all in Forage quality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 103")n 103&")ot;)

Low temperature stress is one of the major negative factors affecting vegetative and reproductive growth of rice. To better understand responses of rice plants to low temperature we analyzed transcriptome expression patterns in glumous flower of cold-tolerant japonica rice variety, Stejaree45, and cold-susceptible variety, HR19621-AC6 at booting stage under cold water irrigation. A total of 2,411 probes were differentially expressed by low temperature in glumous flowers of the two varieties. Some important genes involved in hormone biosynthesis showed variety-specific regulation. Expression of GA20ox3 and GA2ox, among the genes involved in GA biosynthesis, was regulated differentially in the two varieties. Among the genes involved in IAA biosynthesis, YUCCA1 and TAA1:1 showed variety-specific regulation. Among the genes involved in cytokinin biosynthsis and signaling, expression of LOG, HK1 and HK3 was significantly down-regulated only in the cold-susceptible variety. Among the genes involved in ABA biosynthesis, NSY and AAO3 were down-regulated only in the cold-tolerant variety. In general, genes involved in GA, IAA and cytokinin biosynthesis responded to cold temperature in such a way that capacity of those bioactive hormones is maintained at relatively higher levels under cold temperature in the cold-tolerant variety, which can help minimize cold stress imposed to developing reproductive organs in the cold-tolerant variety.
