We developed a polymer pouch using PVP that is water soluble in the precedent study. Yet melt viscosity was so low that it was not possible to produce hemispheric type which is essential for mass production, therefore we used another material to make the polymer pouch. It enabled to figure out a water-soluble transition and mechanic physical property of PEG that is newly chosen, and to blend the PEG with LLDPE and TALC followed by result. So, we could implement an evaluating property on blended proportion. It is important to find out a proper blending ratio throughout an experiment since its property is different or varied followed by each proportion as a water soluble character is conflict to a solid character. With the blending technique we were able to produce the polymer pouch enhanced for a tensile force and an impact intensity maintaining a water soluble character. We could identify a ground solidity effect of the polymer pouch as a result of a direct shear test using the product developed.

Omija (Schizandra chinensis Baillon) has five lignans such as schizandrin, gomisin A, gomisin N, gomisin C and schizandrin C. Its major constituent, schizandrin, has a deterrent effect on nephrotoxicity of cisplatin, blood sugar and an ulcer of the stomach. In this study, we have investigated optimized extraction condition to make high functional beverage by quantifying schizandrin and measuring of browning index. Browning index was used as an index of color deterioration of anthocyanin. Browning index was decreased according to increment in extraction temperature and ethanol concentration. The optimum extraction time, extraction temperature and alcohol concentration levels were 3 hrs, $46^{\circ}C$ and 24% alcohol for high schizandrin concentration and desired browing index.

The influence of tourists on the retail market in Korea continues to grow, and China has become the largest outbound-spending nation in the world. Korea's retail industry must comprehend the sophisticated consumption behavior of Chinese tourists. Hence, we explored how the experiential value of shopping in Korea affected Chinese tourists' satisfaction levels regarding stores and products. Findings from this study suggest entertainment and escapism mediate the effect of experiential value on consumer attitudes toward products and stores. This research was conducted with Chinese female tourists who shopped in Korea during their latest visit to this country. CFA and SEM were implemented using AMOS 20.0. The analysis of survey data produced interesting results. Visual appeal, crowding, and service excellence had positive impacts on entertainment, and they had a positive influence on both store satisfaction and product satisfaction. Regarding escapism, crowding and economic benefits had positive impacts, whereas visual appeal and service excellence had no effects. Results showed that escapism had a negative influence on attitudes toward both products and stores. To be clear, escapism refers to the status of absorption by which consumers are highly occupied with pleasant feelings, therefore, shopping when the motive of escapism is high is likely to be less rational and more impulsive. In this study, the diverse roles of different emotions associated with entertainment and escapism in the context of tourism shopping were identified. The findings provide practical implications for developing retail strategies and highlight the importance of the experiential values of shopping for tourists.

Fiber-reinforced composite laminates have high specific stiffness and strength and are expected to be useful for weight reduction in weight-sensitive industries, such as automotive and aerospace. However, designing composite laminates is often dependent on designer's experience and intuition because of difficulties in determining the number of plies and stacking sequence, which tends to lead to over-design. In this study, optimal design of composite laminates was performed to minimize weight, while withstanding the given load. Based on the enumeration method, all combinations of stacking sequence satisfying the design guideline for composite laminates were considered. Composite laminates were discretized into panels. Optimal number of plies and stacking sequence for each panel were determined considering local load on each panel and contiguity across adjacent panels. Failure index from Tsai-Wu criteria was optimized for strength and buckling analysis was performed for compressive load. Stacking angles of 0, ±45 and 90° were used.

Modern consumers expect the goods which is sewed more sensitive and emotional satisfaction. It is necessary to apply the knowledge of sensibility analysis to the design of car. The design of wheel for car is regarded as important because consumers want to have unique cars and spend on decorating their cars. This study is to understand the image of consumer's idea about the design of wheel for far through the sensibility analysis that is understood from a part of new design way. According to consumers'needs and emotion, the images of 'harmonious', 'fresh' and 'strong' are representative for the design of wheel for car. The wheel of spoke type stands for the image of 'harmonious', the wheel of mesh type for the image of 'fresh' and the wheel of dish type for the image of 'strong'. Therefore, the emotional image that consumers have of the product is extracted by the sensibility Analysis. In turn, the suggestion of a design direction that satisfies the consumers is possible.
