This study examined the potential of export items in Malaysia by investigating the awareness and preference for Korean food products. A high potential product list developed from the literature, included reports about the food export status in Korea and Malaysian food trends. An online survey was carried out with 600 consumers in Malaysia. With 435 valid responses, the average awareness of the Korean food products was 3.13, and the preference was 3.48 on a 5-point scale. The awareness and preference of Korean food products were higher in the 20s-30s group than in the older groups. In particular, the Muslim group had a higher awareness for 'ramyon' than the other groups, and the Buddhist group had a higher preference for 'ginseng beverage' than the other groups. The most well-known and preferred products were ramyon, hot noodles, kimchi, biscuits, fruits & vegetable beverage, and sauce (with Korean traditional sauce)'. Based on these results, the marketing implications of the study findings are discussed.

The purpose of this study is to empirically investigate consumers' clothes shopping orientation factors and perceived risk factors affecting the purchase intention for fashion products in social commerce. For this study, questionnaires were given to 500 adults in their 20s~30s who had experience of using social commerce related to general products or services. To analyze the results of this study, we conducted descriptive analysis, factor analysis, reliability analysis, a chi-square independence test, and hierarchical regression analysis using SPSS 18.0. The results were as follows. First, social commerce users'clothes shopping orientations were classified into the pursuit of pleasure, brand, fashion innovation, trend, and utility, and the perceived risks were classified into the risks related to products, consumer service, loss of purchase opportunity, confidence in the web site, economy, and security. Second, clothes shopping orientation factors and perceived risk factors had a somewhat significant influence on the purchase intention for fashion products. Third, there was a significant difference between sexes regarding the influences of the clothes shopping orientation factors and perceived risk factors for the purchase intention of fashion products. Finally, this study aims to provide useful information for fashion companies to enable them to establish specific strategies that can influence consumers'purchase behaviors through social commerce.

This study examined the service quality attributes of the CVS (Convenient Store) packed meal products by applying the Kano model. The main survey was conducted by a research company using an online survey in the form of a self-administered questionnaire. The 499 samples were limited to customers who had experienced CVS packed meal products within the last months. A total of 14 service quality attributes of the CVS premium packed meal products were categorized as four attractive qualities, one must-be quality, three one-dimensional qualities and six indifferent qualities. According to the Better and Worse quotient designed by Timko, 'coupon and sales promotion event', 'healthy menu configuration', and 'balanced nutrition' had higher levels of the Better coefficient. On the other hand, 'hygiene and cleanliness', 'the delicious food', and 'fresh ingredients' showed a higher Worse coefficient. The results also suggest that each service quality attribute is not a single dimension but a complex attribute. As a result, this research suggests that marketing practitioners should immediately identify consumer's changing perception of quality to attract new customers and prevent existing customers from leaving in the CVS premium packed meal products segment.

The objectives of this study were: (1) to identify differences in consumer attitudes and intentions to recycle fashion products using three types of recycling (including resale, reform, and donation), and (2) to examine the moderating effects of consumer prosocialness on the relationships between attitude and intention for each type of fashion product recycling. Men and women aged 20 years and over were recruited from a marketing research firm panel. Participants completed an online questionnaire incorporating measures for attitudes and intentions to resale, reform, and donate fashion products, prosocialness, frequency of purchasing fashion products, monthly amount of spending on fashion products, and demographic information. Data from 224 participants were analyzed using SPSS 25.0 and PROCESS macro. The results demonstrated that consumers had significantly different attitudes and intentions depending on type of fashion product recycling. Consumers had more positive attitudes toward donation compared to resale and reform types of recycling. Consumer intentions toward resale and donation were significantly higher than their intention to reform. Furthermore, this study confirmed that the attitude-intention gap in fashion product recycling can be explained by individual prosocialness. The moderating effects of prosocialness on the associations between attitude and intention to recycle were significant. The implications of increasing consumers' behavior intention to recycle fashion products was discussed and future research suggestions are provided.

The self-driving roller conveyor system, which transports target products by controlling multiple rollers with a motor, is a logistics system suitable for branching and joining logistics and controlling the alignment of target products, and its utilization is increasing, especially in the food manufacturing process. In this paper, we build a simulation environment using Unity software based on 3D graphic modeling of a self-driving roller conveyor system. In a situation where target products are supplied irregularly in terms of time, a method is proposed that can align products to maintain constant spacing by controlling the rollers. Simulation results show that effective alignment of products is possible by controlling the motor that drives the roller based on sensor data of the product position.

Panax ginseng root has been widely used as an important drug for thousands years in China, Korea and Japan. The main effective components of ginseng have been believed to be saponins. However, ginseng cultivation is very difficult and needs many years for growth. It has already been shown that Panax ginseng callus produces a considerable amount of the same kinds of saponins as in intact plants. Various culture conditions were examined for increased production of ginseng saponins by cell culture. The saponin contents and the growth rates in two cell lines of ginseng callus were compared in static and suspension cultures, rotary and reciprocal shaking cultures. It was shown that the growth rate in rotary shaking cultures of D5-B2K-B2K callus was the highest and ginseng saponin production was most effective in reciprocal cultures of D5-B2K-B2K callus. The saponin content per fresh weight of the culture was 1.03 times higher than that of the fresh ginseng root.

Isolation and identification of algal lytic bacteria were carried out. Nine strains of algal lytic bacteria were isolated by the double-layer method using Anabaena flos-aquae as a sole nutrient. The isolate, AFK-13, showing the highest algal lytic activity was identified as Sinorhizobium kostiense based on the l6S rDNA sequence. The algal lytic experiments of the culture supernatants of AFK-13 demonstrated that the bacterial cell growth reached a maximum at 36-h culture, but the supernatant of 72-h culture exhibited the highest activity. Components among the extracellular products in the crude enzyme of the supernatant from S. kostiense AFK-13 culture were responsible for degradation of cell walls of Anabaena flos-aquae. Algal lytic assay tests of the culture supernatants suggest that the main substances for algal lytic activity could be proteinaceous. The activity of glucosidase was observed highly by polysaccharolytic analysis using the crude enzyme from S. kostiense AFK-13, whereas activities of galactosidase, mannosidase, rhamnosidase, and arabinosidase were also detected in low levels. The molecular weights (MW) of ${\alpha}-\;and\;{\beta}$-glucosidases were estimated to be approximately 50-100 kDa by the ultrafiltration method.

Kou Woan Lao is an oriental-style dairy product, which is coagulated by milk-clotting enzyme from the culture filtrate of lao-chao. The product appears smooth, sweet, slightly wine flavour, and the flavour differs from yogurt. The aim of this study was to search for the optimum model to shorten the period of manufacture, and to improve the quality of Kou Woan Lao. A response surface design was used for studying the effects of addition of carrageenan, locust bean gum, and culture filtrate from lao-chao on the curd firmness, viscosity, and syneresis. Results indicated that the best rheological property, preservative quality and acceptability of Kou Woan Lao could be obtained by the combination of 0.22% carrageenan, 0.21 % locust bean gum and 12% culture filtrate from lao-chao. The curd firmness, viscosity and syneresis of resultant product were 29.3 g, 21,347.7 cps, and 8.92%, respectively and the microstructure of the curd revealed a relatively complete three-dimensional spider web-like structure.

A glucose-limited “pH-stat” continuous culture study of Lactobacillus bulgaricus NLS-4 in an anaerobic condition showed the marked effects of environmental pH on end products, fermentation blances and bioenergetic aspects of the organism. Lactic acid was the major end product of fermentation with minor products, such as acetic acid, formic acid and ethanol throughout the pH range tested. In acidic conditions below pH 6.5, a typi-cal pattern of homofermentation was revealed whereas in alkaline conditions, the metabolic pattern was changed from homofermentation to heterofermentation and led to acquire much energy. This metabolic change was likely due to the pH-dependent lactate dehydrogenase activity. Molar growth yields (Yglc=35.5-44.4) and YATP, $18.5\pm2.5$ in average which was 80％ higher than the value ever postulated seemed to be accounted for less requirement of maintenance energy of the organism in the culture conditions.

Improving public awareness of wood is crucial for expanding the use of wood and establishing a wood culture. In this study, the environment and trends of the public's wood utilization were analyzed using a questionnaire survey and online text mining at a time when eco-friendly practices are gaining popularity. As a result of reducing climatic and environmental concerns and its positive physical and psychological effects, the use of wood is predicted to rise in areas intimately connected to everyday living, such as wood furniture, wooden structures, and interior materials. Nonetheless, there was a negative awareness that wood was expensive, difficult to maintain, and associated with deforestation. The correlations between wood-related search terms on major Korean portal sites were analyzed and categorized into five groups: Wooden architecture, cultural education, woodworking, wood industry, and wood policy. As a building material, wood was seen as more traditional and friendly than reinforced concrete and stone. Eighty-six percent of respondents expected to utilize wood as a building material in the future, regardless of whether the wood is domestically produced or imported. Sixty-five percent responded favorably about the effects of wood on the health of wooden home inhabitants. It is believed that both active publicity and quantifiable value analysis of human and environmental friendliness are required to increase pro-environment awareness of wood utilization.
