Many online stores bring features that can build trust in their customers. More so, the number of products or content services on online stores has been increasing rapidly. Hence, personalization on online stores is considered to be an important technology to companies and customers. Recommender systems that provide favorable products and customer product reviews to users are the most commonly used features in this purpose. There are many studies to that investigated the relationship between social presence as an antecedent of trust and provision of recommender systems or customer product reviews. Many online stores have made efforts to increase perceived social presence of their customers through customer reviews, recommender systems, and analyzing associations among products. Primarily because social presence can increase customer trust or reuse intention for online stores. However, there were few studies that investigated the interactions between recommendation type, product type and provision of customer product reviews on social presence. Therefore, one of the purposes of this study is to identify the effects of personalized recommender systems and compare the role of customer reviews with product types. This study performed an experiment to see these interactions. Experimental web pages were developed with $2{\times}2$ factorial setting based on how to provide social presence to users with customer reviews and two product types such as hedonic and utilitarian. The hedonic type was a ringtone chosen from Nate.com while the utilitarian was a TOEIC study aid book selected from Yes24.com. To conduct the experiment, web based experiments were conducted for the participants who have been shopping on the online stores. Participants were a total of 240 and 30% of the participants had the chance of getting the presents. We found out that social presence increased for hedonic products when personalized recommendations were given compared to non.personalized recommendations. Although providing customer reviews for two product types did not significantly increase social presence, provision of customer product reviews for hedonic (ringtone) increased perceived social presence. Otherwise, provision of customer product reviews could not increase social presence when the systems recommend utilitarian products (TOEIC study.aid books). Therefore, it appears that the effects of increasing perceived social presence with customer reviews have a difference for product types. In short, the role of customer reviews could be different based on which product types were considered by customers when they are making a decision related to purchasing on the online stores. Additionally, there were no differences for increasing perceived social presence when providing customer reviews. Our participants might have focused on how recommendations had been provided and what products were recommended because our developed systems were providing recommendations after participants rating their preferences. Thus, the effects of customer reviews could appear more clearly if our participants had actual purchase opportunity for the recommendations. Personalized recommender systems can increase social presence of customers more than nonpersonalized recommender systems by using user preference. Online stores could find out how they can increase perceived social presence and satisfaction of their customers when customers want to find the proper products with recommender systems and customer reviews. In addition, the role of customer reviews of the personalized recommendations can be different based on types of the recommended products. Even if this study conducted two product types such as hedonic and utilitarian, the results revealed that customer reviews for hedonic increased social presence of customers more than customer reviews for utilitarian. Thus, online stores need to consider the role of providing customer reviews with highly personalized information based on their product types when they develop the personalized recommender systems.

The purpose of this study was to explore global consumer behavior with fashion products, Korean fashion products, and Korean traditional fashion products (i.e., Han-Bok). Clothing selection criteria for fashion products and Korean fashion products were included as major constructs far the comparison among global consumers based on their nationality. Other consumer behavior variables were shopping place, buying frequency, purchase experience/plan, preferred brand, purchase items, information source, purchasing usage, and the product evaluation of Hanbok. A convenience sample of 236 global consumers was selected for this study. A questionnaire was pilot tested, and the revised questionnaire was used for the interview survey. Descriptive statistics and ANOVA were used for data analysis. Various nationality were existed such as Europe, North America, Japan, China, South East Asia. The results indicated that the most important criteria for fashion buying were design, fit, and size in order. Fit, size, and color item from buying criteria were significantly different among global consumers by nationality. Country of origin was found as less important factor among global consumers. Department store was most favorable shopping place, and once a month is the most mentioned category in buying frequency. Preferred brands were Levi's, Polo, Gucci, and Prada, etc. Secondly, regarding the evaluation of Korean fashion products, textile quality was highly evaluated. Significant difference except design/style category were existed among global consumers by nationality. Thirdly, regarding the evaluation of Hanbok, the product evaluation of Hanbok highly represented as special event clothing, unique image, beautiful details and oriental beauty in order. Significant difference in good quality of textiles, oriental beauty, coordination with good colors and fabrics, beautiful details and unique style and design were existed among global consumers by nationality.

This paper aims to analyze the characteristics of the contemporary Chinese fashion market and the competitiveness of Korean fashion brands in China. Fashion professionals experienced in both the Korean and Chinese fashion markets participated to investigate the Shanghai market and consumers. The results of in-depth interviews show that Shanghai is the most favorable city among Tier 1 cities for Korean fashion brands planning on entering into the Chinese market. Shanghai consumers are open to international brands and highly prefer newness in fashion. Contemporary menswear was selected as a potentially big market due to the increase of unique, young, upper-middle-class male consumers. The Korean fashion brands' strength is that they are capable of satisfying Shanghai consumers with excellent product planning and sensory design capabilities. Their disadvantage is that their brand recognition is weaker than that of global and international brands, and their ability to localize to the Chinese market is weak. The opportunity comes is from the Korean Wave, which is a positive for Korea's products and has good geographical access. The threat is that the Shanghai market is fiercely competitive; having access to many worldwide brands, and the competitiveness of Chinese brands is on the rise. To enter the Shanghai market, creative design ability, trendy product development, skill, and appropriate PR methods such as using Korean culture contents would be required to satisfy the young, powerful consumers in Shanghai.

Background: Rice bran is a by-product of the rice-milling process, which remains largely underutilized; however, efficient processing treatments may improve its feeding value for chickens. This is of great economic and environmental importance, as this can lower the production costs, and offer an opportunity for valorization of a low-quality agricultural by-product, to a high-value feed source. Methods: This experiment was conducted to study the effect of extruded rice bran on performance and phosphorous (P) bioavailability in broiler chickens. In a completely randomized design, 200 seven-day-old broilers (Cobb 500) were allotted to five treatments with five replicates per treatment and 8 chicks per replicate, and fed with their respective diet during the starter (8 to 21 days) and grower (22 to 42 days) periods. Diets were a basal corn-soybean based diet (T1), or diets containing 20 % rice bran (T2), 30 % rice bran (T3), 20 % extruded rice bran (T4), or 30 % extruded rice bran (T5). Results: Birds feeding on T4 and T5 diets had a higher body weight gain and lower feed-to-gain ratio compared to those feeding on T2 and T3 diets (p < 0.05). Birds receiving diets containing extruded rice bran had higher total P availability and tibia ash content, as compared with those receiving diets containing un-extruded rice bran (p < 0.05). Relative weight of the pancreas was higher in birds receiving T2 and T3 diets. Conclusions: The results confirmed the beneficial effect of extrusion treatment of rice bran on performance and P availability in broilers. Up to 30 % extruded rice bran may be included in the broiler diet without apparent adverse effects on the performance.

Packaging of shopping bag is a 'silent salesman' which plays an important role in marketing communication due to the increase of self-service outlets and changing lifestyles of customers. Retail shopping bags, which are defined as bags provided by retailers to customer as a means of transporting merchandise, are a type of secondary packaging. This study explored the effect of a fashion product's shopping bag types in sense of shopping value, customers' response, attitude toward advertising, and purchase intention. Data was analyzed by factor analysis, frequency analysis, correlation, structural equation modeling using SPSS 18.0 and AMOS 18.0. The results of this study were as follows. Consumers' responses about shopping bags show that there are some differences between consumers who have either hedonic or utilitarian shopping value. Hedonic shopping value influences on consumers' response as unique, interesting, and attention; however utilitarian value affects prestige in addition to those four significant factors. Therefore, this study shows that consumer response is different in accordance with shopping value. Thus, using the various types of shopping bags can be influenced on effective advertising. It will also great effect on marketing activity with lower cost. The significant result from this study has proven that the shopping bag is correlates to the definition of pop art today because it can offer an opportunity to look at, play with and buy sophisticated visual stimulus. Therefore, retail and brands have to concern about shopping bag considering their decisive role in the apparel market.

The rise of K-Pop in the latecomer environment is unusual. There is little research on K-Pop from the catch-up perspective though it would yield some insight into a strategic direction of creative industries in the latecomer environment. Thus, this study aims to compare the firm capability, market development, and product strategy of K-Pop firms with ones of manufacturing firms during the catch-up period. It reveals first that K-Pop firms developed project execution capability to carry out discrete projects effectively by adopting in-house (vertical) system in music production and increasing the size of firms. Second, they pursued global market and utilized the window of opportunities based on a proven music genre. Third, K-Pop firms pursued the incremental innovation in the product development. Since these characteristics have many similarities with the catch-up strategy in the manufacturing sector, Korean catch-up experience could provide valuable insight into the development of creative industries in Korea.

Since the introduction of carbonated drinks in the 1950s, 'cola' and 'cider'along with orange juice, the dominator of the juice market, have been two main streams of the Korean beverage market. This market pattern has caused the following effects; a. Economical loss due to the import of foreign brands - royalty payments to x company. b. Loss of opportunity to develop a domestic beverage market. c. Inflow of an unfiltered foreign culture. This study shows a change in the Korean beverage market. In the 1980s. consumers' tastes started to change as a trend of developing beverages using traditional Korean ingredients started to begin. On the basis of this change, I would like to discuss the desirable path in developing beverages using traditional ingredients. 'Traditional ingredients'refers to the ingredients that the Korean people have enjoyed within the course of their life, whether it be via food or beverage. These ingredients have been chosen by our people as first rate for centuries. How to modernize and develop these work-in-progress products is the desirable direction for the development of drinks using traditional Korean ingredients. This study also shows various examples of how Korean traditional ingredients and the Western scientific civilization can fuse together to develop a modern and value-added product. One project in particular, created a method of producing a beverage using rice a simple traditional ingredient, marking it a hit product. Through this example, I present the desirable direction of how to develop a modernized drink using traditional ingredients that can change both the consumers' current value on the Korean beverage market as well as create a new pattern of consumer tastes.

The rapid growth of e-commerce has made both companies and customers face a new situation. Whereas companies have become to be harder to survive due to more and more competitions, the opportunity for customers to choose among more and more products has increased. So, the recommender systems that recommend suitable products to the customer have an important position in E-commerce. This research introduces collaborative filtering based recommender system which helps customers find the products they would like to purchase by producing a list of top-N recommended products. The suggested methodology is based on decision tree, product taxonomy, and association rule mining. Decision tree is used to select target customers, who have high possibility of purchasing recommended products. We applied the recommender system to a Korean department store. The methodology is evaluated with the analysis of a real department store case and is compared with other methodologies.

Hydrolysis of biomass for the production of fermentable sugar can be improved by the addition of surfactants. In pulp and paper mills, lignin, which is a by-product of the pulping process, can be utilized as a fine chemical. In the hydrolysis process, lignin is one of the major inhibitors of the enzymatic breakdown cellulose into sugar monomer. Therefore, the conversion of lignin into a biosurfactant offers the opportunity to solve the waste problem and improve hydrolysis efficiency. In this study, lignin derivatives, a biosurfactant, was applied to enzymatic hydrolysis of various lignocellulosic biomass. This Biosurfactant can be prepared by reacting lignin with a hydrophilic polymer such as polyethylene glycol diglycidylethers (PEDGE). In this study, the effect of biosurfactants on the enzymatic hydrolysis of pretreated sweet sorghum bagasse (SSB), oil palm empty fruit bunch, and sugarcane trash with different lignin contents was investigated. The results show that lignin derivatives improve the enzymatic hydrolysis of the pretreated biomass with low lignin content, however, it has less influence on the enzymatic hydrolysis of other pretreated biomass with lignin content higher than 10% (w/w). The use of biosurfactant on SSB kraft pulp can increase the sugar yield from 45.57% to 81.49%.
