  • Viral diseases, especially Barley yellow mosaic virus (BaYMV) and Barley mild mosaic virus (BaMMV) have been most serious in barley fields. In this study, we investigated the effect of different level of resistance to viral diseases on the plant growth and yield in malting barley. In diagnosis of virus infection, BaYMV and BaMMV were detected in 'Doosan 29' (susceptible), however, 'Jinyangbori' (moderate susceptible) and 'Hopumbori' (moderate) was infected by only BaYMV. Plant height was restrained about 8~29% in overwintered plant regeneration stage depending on the resistant of each cultivar. The culm length damaged also to 9~12% by BaYMV infection. The tiller numbers reduced to 10~14% in overwintering season, however, the head numbers in harvest season more decreased to 26~33%. Heading date was delayed to 3~3 days by the infection. In examination of yield components, 1,000 kernel weight and $\ell$ weight reduced according to culrivar's resistant degrees to 4.0~6.4% and 1.0~4.2%, respectively. The yield of abortive grain was doubled in BaYMV infection comparing to non-infested field. Three varieties tested in the non-infected field over two years were not significantly different for yield potential with ranges of 509kg~632kg/10a. However, significant yield reduction was observed in 'Saessalbori' and 'Baegdong' with ranges of 77~177kg/10a as compared to 'Hopumbori' (467 kg/10a) when tested in the virus-infected field. Yield potentials of these cultivars reduced by 26~43%, respectively, in the virus-infected field as compared to those in the non-infected field.

  • Freshwater fish fauna and community structure were surveyed through 21 lakes in the Yeungnam area including Gyeongsangbukdo and Gyeongsangnamdo provinces, Korean Peninsula from April 2008 to October 2009. Among 21 lakes, 16 lakes belong to the Nakdong River and 5 are independent drainages. From the present study, 61 species (44 genera, 15 families) were collected including 32 cyprinid species (52.5%), 6 cobitid species (9.8%) and so on. The dominant and subdominant species in aspect of the number of individuals were Hypomesus nipponensis (26.6%) and Squalidus gracilis majimae (14.8%), respectively. On the other hand, in aspect of in biomass, dominant and subdominant species were Lepomis macrochirus (19.8%) and Cyprinus carpio (14.7%), respectively. Among 61 examined species, there were found 20 Korean endemic species and 2 Korean endangered species (Pseudobagrus brevicorpus and Pungitius kaibarae). P. brevicorpus was found in Yongyeonji and Yeongcheonho, and P. kaibarae in Yongyeonji. In addition, 5 exotic species were identified such as Cyprinus carpio nudus (leather carp), Carassius cuvieri, Hypophthalmichthys molitrix, Lepomis macrochirus and Micropterus salmoides. Interestingly, a bluegill L. machrochirus appeared dominant or subdominant species in 5 of 21 examined lakes. Five species introduced from the other rivers in Korean Peninsula were additionally described. In the present study, it was first reported that Micropercops swinhonis inhabits in the Nakdong river basin. The fish species diversity, evenness and dominant indices were examined, and a dendrogram based on similarity indices of inhabiting species among the 21 examined lakes was constructed and discussed.

The findings are as follows. The effects of sommelier service quality on positive emotions were respectively significant in specialty factor(${\beta}$=.257, p<0.001), reliability factor(${\beta}$=.314, p<0.001), and responsiveness factor(${\beta}$=.387, p<0.001). And the effect on negative emotions was significant in specialty factor(${\beta}$=-.178, p<0.05). Meanwhile, the result of the effect on the revisit factor of sommelier service quality was significant in reliability factor(${\beta}$=.286, p<0.001). And the effects of customers' emotional response on revisit factor were significant in positive emotion factor(${\beta}$=.350, p<0.001) and negative emotion factor(${\beta}$=-.195, p<0.01) respectively. As the emotional responses based on sommelier service quality had a great impact on customers' revisit intention according to positive or negative emotions, it is necessary for food service industry operators to improve customer satisfaction with consolidating the factors to give customers positive emotions which eventually can lead them to revisit wine restaurants.

  • The quality characteristics of three non-genetically modified (GM) LRS soybean cultivars free of LOX 1, 2 and 3, such as Jinyang, Hayoung and Daebok, were compared to the characteristics of Taekwang, a soybean with LOX 1, 2 and 3 and general contents of raffinose and stachyose. Taekwang was used as a control soybean. The weights of 100 for Taekwang and Hayoung soybeans were significantly higher than those of the other samples. The crude-protein contents of the Jinyang and Hayoung soybeans were significantly higher than the crude-protein content of the Taekwang soybeans. Similar tofu yields were observed in the Taekwang, Hayoung and Daebok soybeans. The highest tofu yield was observed in the Hayoung soybeans. The isoflavone contents of the soybeans and tofu were 1.4-1.6 times and 1.8-3.4 times higher than the contents of the control soybeans, respectively. The total phenol contents of the Hayoung and Daebok soybeans were significantly higher than the contents of the control soybeans. Additionally, the total phenol and flavonoid contents were significantly higher in the tofu made from the LRS cultivars than in the tofu made from the control cultivar. The antioxidant activities of the Taekwang soybeans were higher than the antioxidant activities of the LRS-cultivar soybeans. However, the antioxidant activities of tofu made from the LRS cultivars were significantly higher than the antioxidant activities of tofu made from the control cultivar. The results suggested that the soybeans of the LRS cultivars were suitable for tofu products. The Hayoung cultivar may be the most suitable due to its higher crude protein and isoflavone contents and its significant antioxidant activity.

  • The anchovy, Engraulis japonica, were prepared with two different saltconcentration of 20%, 10% which was added 2, 5, 8 and 10 % of grind garlic(LSA 1, 2, 3, 4) and garlic juice(LSB 1, 2, 3, 4), respectively. The changes of such factor during fermentation of anchovy as general composition, salt concentration, titrable acidity and sensory evolution were analyzed. In addition, chewiness, taste, garlic flavor and off-flavor wastested it's results were belived that the more garlic amounts added the more rotten smell has been disappeared. In the view of sensory perception. sample of 90 days fermentation is supposed as the best period of fermentation. The contents of moisture and crude fat decreased while, those of ash and crude protein were changes little during fermentation of low salted anchovy. Titrable acidity decreased in all experiment groups during anchovy fermentation, its contents at 30 days fermentation were ranged between 1.4~ 1.8g/100g, but it dramatically decreased to 0.6~l.1g/100g at 90 days fermentation.
