As the microelectronics technology is developed, new types d smart intelligent produce are being emerged. OSD user interface is one of the critical factor in this kind of product, especially brown goods and information devices, as it is responsible for input and output function. OSD is being treated as accompaniment to hardware in spite of its importance, and therefore is developed from only simple and separate usability testing based on performance measurement. This study propose a usability evaluation method of OSD based on subjective preference to support existing usability testing. The purpose of this analysis is to make dear what is important factor and how its preference level is from the user's viewpoint. The various attributes of OSD are clarified from user's questionaire and interview, and orthogonal array is generated with specifed factor levels.

This study analyzed the failure cases of new products for relative benefits among various factors related to the characteristics of innovation, which is an important factor in the consumer persuasion process among Rogers (1995)'s innovation diffusion theory. This is because relative profits are the most influential factor in consumers' intention to adopt among the characteristics of various innovative products (Holak and Lenmann, 1990). As a result of analyzing the failure cases of new products of six companies, these products lacked relative profits for existing products in common. Relative profits are factors that are measured in the economic sense or are measured by social advantages, convenience, and satisfaction, and are the most important factors compared to other factors such as suitability, complexity, observability, and applicability. In the end, it was found that relative profits compared to existing products are an important success factor in persuading consumers of new products.

The purpose of this study was to determine the optimum Platycodon grandiflorum root concentrate (PGRC, $65^{\circ}Brix$), fermented P. grandiflorum root extract by Lactobacillus plantarum (FPGRE, $2^{\circ}Brix$), and cactus Chounnyouncho extract (Cactus-E, $2^{\circ}Brix$) for preparation of PGRC stick product with FPGRE using response surface methodology (RSM). The experimental conditions were designed according to a central composite design with 20 experimental points, including three replicates for three independent variables such as amount of PGRC (8~12 g), FPGRE (0~20 g), and Cactus-E (0~20 g). The experimental data for the sensory evaluation and functional properties based on antioxidant activity and antimicrobial activity were fitted with the quadratic model, and accuracy of equations was analyzed by ANOVA. For the responses, sensory and functional properties showed significant correlation with contents of three independent variables. The results indicate that addition of PGRC contributed to increased bitterness and acridity based on the sensory test and antimicrobial activity, addition of FPGRE contributed to increased antioxidant activity and antimicrobial activity, and addition of Cactus-E contributed to increased fluidity based on the sensory test, antioxidant activity, and antimicrobial activity. Based on the results of RSM, the optimum formulation of PGRC stick product was calculated as PGRC 8.456 g, FPGRE 20.00 g, and Cactus-Ex 20.00 g with minimal bitterness and acridity, as well as optimized fluidity, antioxidant activity, and antimicrobial activity.

The terminals of e-Book(electronic Book) are classified into two types which consist of special-purpose terminal equipment and general-purpose terminal equipment. Although the terminal products inr the two types have had a strong race in the e-Book market each other, both enterprises and consumers want the two type to remain persistently with competition in good faith. Therefore, it is necessary for each type camps to find blue ocean by establishing differentiation strategies of each type. In this paper, we designed the research model that independent variables consist of hardware quality and software quality, dependent variable is user satisfaction, moderator variable is the terminal type. Through the research model, we investigated factors having a influence on the user satisfaction of the e-Book terminal that consists of hardware and software. In particular, we investigated if the degree of the influence is different between the two types. As a result, we got conclusions as followings. First, the quality of hardware and software in the terminal had significant influences on the user satisfaction. Second, the degree which the hardware quality has influenced user satisfaction was not different between the two types, but the degree which the software quality has influence on user satisfaction was different between the two types. As a implication of this result, we found that special-purpose terminal provider need to establish a strategies for raising the quality of e-Book viewer to provide different product from general-purpose terminal.

The purpose of this study was to develop an effective marketing strategy for socks made of paper mulberry fiber, a new natural fiber, by understanding consumers' concerns and perception about the product and its quality in several dimensions. The first survey determined their perception of the products' image before using it. The second survey gauged consumer satisfaction with product quality after a two-week home-use test. Factor analysis using Cronbach's a and ANOVA analysis were performed for statistical analysis. In conclusion, consumer image perceptions of socks of mulberry fiber were classified into four categories -'practicality', 'wellbeing', 'high-quality' and 'traditionality'. The survey revealed differences between men's and women's perception of the 'practicality' and 'high-quality' factors. The women recognized a mulberry fiber sock as being more practical but of lower quality than did the men. And the quality satisfaction of the product was classified into four factor 'durability', 'suitability, 'wearability' and 'care-easiness'. In the case of 'suitability', men were more satisfied with the product than the women and in 'suitability' and 'wearability', a group of over 40' year-old consumers was more satisfied. The analysis of a relationship between image perception and satisfaction showed that a consumer group that perceived this product to have more 'practicality', 'high-quality' and 'well-being' was also more satisfied with the product. However, the 'traditionality' factor was unrelated to consumer satisfaction.

The Internet of Things (IoT) is characterized as the market where various companies compete for the same consumers. Thus, there are differences in functions and performance provided by the main business area and other characteristics of the service providers. This paper investigates whether satisfaction with the service provided depends on the characteristics of the operator by using sentiment analysis of comments. To achieve this goal, word importance analysis and sensitivity analysis are conducted on 34,310 reviews of 41 applications registered in the Google Play. The review analysis was conducted at various levels, including TD-IDF (Term frequency-inverse document frequency) value of keywords, service sectors, the origin of providers, and domestic/foreign providers. The results show that users' overall assessment of IoT services was found to be low, and smart homes received relatively high reviews compared to other services, and manufacturing-based and overseas providers received relatively higher evaluations than others.
