In the consumer products industry, it has been highly desirable to develop objective test methods to replace subjective evaluation methods. In developing an objective test method, subjective evaluation data should be on a linear scale. According to Thurstone's theory of comparative judgment, a%-preference from a paired-comparison test can be converted to a linear-scale value. The required number (N) of paired-comparison tests increases dramatically as the number of products increases. This problem should be solved by classifying the total products into several subgroups consisting of 3-4 products in each group. By doing so, it can not only significantly reduce the number of required paired-comparison tests, but it can also obtain more reliable, reproducible data.

More government's policy supports than current are necessary time first of all because Korea game industry is growing vigorously centering around On-line game and Mobile-game. Korea Government is progressing game industry promotion policies actively, and these may accelerate developed speed of Korea game industry in the near future. But, we are time that feedback of government's game industrial policies is necessary now through comparison with game industry policy of Northeast Asia area game Industry policy of area. Therefore, In this paper we did study improvement assignment of Korea game industrial policy through comparison with Game industrial policies of the Korea, China and Japan.

The study investigated the effects of SNS usage on 20s and 30s female SNS users' internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders based on objectification theory and social comparison theory. The study examined differences on SNS usage and body image variables between high and low groups of SNS envy and self-compassion. Social Network Service (SNS) is used as a contemporary marketing tool for brands and companies. It also influences the body image of female SNS users. The survey used an online survey company for female SNS users in their 20s and 30s to analyze the effect of SNS usage. The results showed that SNS usage significantly impacted the internalization of a thin body, body surveillance and appearance upper comparison. The internalization of thin body also had a significant impact on body surveillance and appearance upper comparison. Appearance upper comparison positively affected body dissatisfaction and eating disorders. Finally, the group with higher SNS envy showed higher SNS usage, internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders. The group with higher self-compassion showed opposite results. This study provided a theoretical expansion for a SNS and female body image study with objectification theory and social comparison theory. It also suggests positive SNS marketing strategies use for brands. Lastly, this study emphasized the importance of the proper use of SNS to protect the body image of SNS users.

SNS (social networking service) plays an important role in delivering information regarding fashion brands and providing a space for communication between fashion retailers and SNS users, as well as between users. This study primarily focuses on exploring the relationships among the motivation of SNS users and social comparison, clothing purchasing behaviors and the difference in the relationships according to individual characteristics. An online survey was conducted on Chinese female consumers in their 20's and 30's who had experience in fashion SNS. A total of 297 women completed online survey. The results of the study revealed that: (1) consumers who have stronger motivation of information seeking and interpersonal communication through fashion SNS reached more active upward comparison and peer comparison accordingly; (2) upward comparison had a significant effect on conspicuous consumption and bandwagon, while peer comparison had no significant effect; and (3) the self-esteem of fashion SNS users significantly moderated the effect of social comparison on conspicuous consumption and conformity consumption. This study contributed to expanding the knowledge on the relationships among the motivations of SNS users and social comparison, and shed light on Chinese SNS users' characteristics and purchasing behaviors in the fashion SNS context. This study also provides vital implications to fashion brands and retailers.

The purpose of this study is to learn the current perception of Total Smart Mirror Display devised with IoT, focused on Hair beauty industry. In detail, this study is to analyze domestic and foreign precedented case studies and conditions of Smart Mirror in beauty industry, and to learn, through survey, the real condition of use of Hair Smart Mirror, which is devised and applied according to the actual state of our country. First, the mean comparison for Total Smart Mirror by gender showed that Function1, Technology 2 and 3 had differences. Second, the mean comparison each by age, external design, function, marketing and technologies showed that Function 4, Marketing 1 to 3, Technology 1 and 3 had differences.

This paper is an inquiry into the patterns of technological innovation of bio - industry in Korea in comparison with the worldwide patterns. In another words, this study wants to check whether the patterns of technological innovation of bio - industry in Korea differ front those in advanced countries or not. The comparison is based on the theory of science - based industry asserted by Seol (2001) and Cho (2001). There are no specific difference in the patterns of technological innovation such as science - based innovation, capitalization of science, industries leading by scientific fields, the importance of venture firms for commercialization, high level of R&D expense to sales. Also the order of fields by size is similar to worldwide patterns. But the size of microbiology is bigger than that of worldwide patterns. The strength in microbiology may be the country specific features of Korea, like platform technology of Germany.

In this paper presents comparison of performance of flexible solar cells construction applied to curtain walls. The proposed paper compares power generation for curtain walls of various shapes using flexible PV. Through the comparison of performance, the power generation was compared by installing various types of flexible PV on the air layer of double windows. By comparing the measured power generation, it is possible to find an optimal flexible PV shape that can be applied to a curtain wall. Flexible PV installation was divided into diagonal, S and W shapes. As a result of comparison, the amount of power generation when there was no flexure of flexible PV was large. Also, as the angle with the light source increased, the power generation decreased. Therefore, it is necessary to study the structure which can fix the PV more than the flexible PV and to be able to direct the sun without distortion.

Electron beam-induced crosslinking of polycaprolactone (PCL) films containing various crosslinking agents (CAs) was investigated in this study. PCL films containing various CAs prepared by a solution casting method were irradiated by electron beams at various absorption doses and the irradiated PCL films were investigated in terms of their crosslinking degree, thermal and mechanical properties, and biodegradability. Based on the results of the crosslinking degree measurement, triallyl isocyanurate was found to be most effective for the electron-beam induced crosslinking of PCL films. The results of the UTM, DMA, and TMA revealed that the thermal and mechanical properties of the crosslinked PCL films were greatly improved in comparison to those of the pure PCL. The results of the enzymatic degradation test revealed that the biodegradability of the crosslinked PCL films was reduced in comparison to that of the pure PCL.
