Since B2C EC websites not only become a valuable channel for selling goods to customers and for communicating with the potential clients, but also offer companies an important vehicle for attaining competitive advantages in the new digital economy, the design and content of website must reflect its business goals and customers' needs. However, as little empirical evidence on the effect of B2C EC website contribution of firm performance exist, the functionality of B2C EC website has been decided voluntarily from its business experience. Hence, there has been a call for a rigorous empirical studies to examine the function level of an B2C EC website application. The purpose of this study is to examine the relationship between the function level of B2C EC website and its performance considering the characteristics of B2C EC strategy as moderating variable. 125 questionnaires from internet shopping malls which sell physical goods direct to an individual end consumer were collected. The results showed that four factors(price, product recognition, reliability enhancement, and purchase confidence) affect positive effects on the performance of shopping mall, and the characteristics of B2C EC strategy can be considered as a significant moderating variable between price factor and the performance of shopping mall.

Hesperetin (3',5,7-trihydroxy 4'-methoxyflavanone) and its glycoside hesperidin (hesperetin 7-rhamnoglucoside) in oranges have been reported to possess pharmacological effects related to anti-obesity. However, hesperetin and hesperidin have not been studied on suppressive effects on appetite. This study examined that hesperetin and hesperidin can stimulate the release of cholecystokinin (CCK), one of appetite-regulating hormones, from the enteroendocrine STC-1 cells, and then examined the mechanisms involved in the CCK release. Hesperetin significantly and dose-dependently stimulated CCK secretion with an $EC_{50}$ of 0.050 mM and increased the intracellular $Ca^{2+}$ concentrations ($[Ca^{2+}]_i$) compared to the untreated control. The stimulatory effect by hesperetin was mediated via the entry of extracellular $Ca^{2+}$ and the activation of TRP channels including TRPA1. These results suggest that hesperetin can be a candidate biomolecule for the suppression of appetite and eventually for the therapeutics of obesity.

Seaweeds are large algae that grow in a saltwater or marine environment. There are over 400 species of seaweeds in the bay of Korea. Most seaweeds are divided into three groups according to their color : the green seaweeds(division Chlorophyta), the brown(Phanphyta) and the red(Rhodophyta), Seaweeds have been harvested for use as food, fertilizer, animal feed and medicines for thousands years. In the past decade, there has been increasing interest in using seaweeds for animal feedstuffs and feed supplements as their health qualities are becoming better known. In this review some perspectives on nutritional values and the role of functionality ingredients of various seaweeds will be also discussed. Ecklonia cava kjellman(EC), a perennial seaweed, is one of the main components of the marine forests along the East and South coasts of Korea. We conducted three experiments to evaluate the nutritional values of EC and the crude lectin extracted residues from EC(LEEC) and to investigate their dietary effects on productivity and immunocompetence in poultry. The crude protein content of EC was relatively low(about 10 ％) and its amino acids were poorly available. But, the results of our study suggested that EC can be used into broiler feed up to 3 ％ without any adverse effect, if its nutritional values are well evaluated prior to use. Similar results of dietary LECC up to 1.0 ％ level on egg production and egg quality have been obtained in layers. The concentrations of serum TNF-${\alpha}$ after Salmonella challenge were rapidly increased in accordance with the level of LEEC. These results indicated that LEEC can be used as a feed additives for enhancing of immunocompetence in poultry.

Tea is a pleasant, popular and safe beverage in the world. During the past decade, epidemiological studies have shown that tea catechins intake is associated with lower risk of cardiovascular disease. Tea provides a dietary source of health-promoting components to help humans reduce a wide variety of cancer risks and chronic diseases. The antioxidative activity of tea-derived catchins has been extensively studied. The antioxidant effect is a synergistic action between catechins e.g. EGCG, EGC, ECG, EC, pheophytins a and b, and other components in tea leaves, which aye more bioavailable for human body. Green tea has a Higher content of catechins than other kinds of tea. Green tea extract with hot water has high potential and more efficiency to reduce cancer risk than any other tea products or pure EGCG. Protein, iyon, and other food components may interfere with the bioavailability of ten catechins. Interaction of catechins with drug affects the cancer-preventive activity of some cancer-fighting medication. Further studies are required to determine the bioavailability of tea catechins and cancer-preventive functionality.

AS EC is expanded and activated, many message standards, EDI, XML, UDF, etc are defined and is used at various business part. But the existed translator supports only one mapping translation, for example, EDI-to-UDF, UDF-to-EDI. So many user must be introduced a new translation when new business(message standard) is beginning, To solve this problem, we propose XConverter System as registering mapping information which is able to transform to user requested format using same translator even though it is transferred any formatted message in this paper. Also, We design and implement this system which is capable to integrate with existed legacy system, including DB transformation functionality. The .XConverter System supports changing the business message format to the common user used message format. And this system easily migrates with existed legacy system because DB transform module is component. Therefore, The proposed System is more various and flexible than the other translation system that provide just one mapping transformation.

In this study, we studied the photocatalytic functionality such as deodorant, antibacterial, antistatic of polyester fabrics treated with visible-light responsive photocatalyst. According to UV/visible spectrometry result, the UV-visible peak of visible-light responsive photocatalyst was found to be red shift at 420 nm sensitive in the visible light region. Also, the deodorizing and antimicrobial performance were shown to be retained more than 99% both before washing and even after 25 times washing. According to washing durability of polyester fabrics treated with visible-light responsive photocatalyst, the reduction effects for gas such as ammonia, trimethylamine, formaldehyde and toluene after 25 times washing appeared to be retained as much as before washing. At both before washing and after 25 times washing, antistatic property showed frictional voltage of approximately 250V.
