In this study, differences of texture image and preference for men's suit fabrics according to mechanical properties, hand and fabric information were investigated. 55 subjects evaluated texture image and preference of 12 kinds of wool blended fabrics. For statistical analysis, t-test and pearson correlation coefficients were used. The results were as follows: Most of mechanical properties effected on texture images, and bending property and shearing property were effected on tactile preference and purchasing preference. For hand, objective hand values showed correlations with subjective texture images and preferences, but THV had almost no correlations. In sensory images according to presence of fabric information, fabrics were evaluated thinner, lighter, more pliable and smooth by cognition of wool blending ratio. For sensibility images, fabrics were evaluated more refined, intellectual, dignified and less practicable after recognize of wool blending ratio. In preferences, tactile preference was increased and purchasing preference was decreased after recognize fabric information. Therefore, significant differences of texture image and preference were observed according to presence of fabric information.

LED lightings combined with IT technology can provide variable illumination environments that can be controlled by users according to their emotional need and preferences. This is one of the most beneficial functions compared with conventional lightings offering only fixed color and brightness. There is however lack of analysis data for creating practical lighting solutions satisfying user preferences in a wide range of applications from residential to commercial places. To materialize the technical advantages of user-controllable LED lightings, more observation data are required in various situations. Therefore, dissimilar emotional needs are determined in the present study for compartmental office spaces (staff lounge room, meeting room and desk job place) through subjective experiments by 45 observers. The optimum lighting conditions (CCT and illuminance) are finally obtained using Response Surface Method and relevant prediction functions are also deduced. The final outcome can be applied for making user-preferred office illumination products.

The purpose of this study was to analyze factors affecting US beef consumption intention in the future, to identify the causes of US beef import growth and to derive implications and strategies for domestic beef producers. Since the KORUS FTA was signed in 2012, US beef imports in 2017 totaled 379,064 tons, an annual increase of 3.5 percent. US beef imports have been steadily increasing due to cuts in FTA tariffs and changes in consumer preferences. The data used in this study utilized a sample of 3,290 grocery purchasers from the Korea Rural Economic Institute's 2016 Food Consumption Behavior Survey. The analytical method used the Ordered Logit Model to analyze what factors influence a consumer's subjective evaluation. As a result, the major factors affecting US beef consumption intention in the future are price, taste and safety. In particular, it has to do with the recent surge in U.S. imports of good-tasting chilled meat. Because chilled meat does not differentiate the market from Hanwoo beef produced in Korea, it is necessary to have differentiated taste and low price through cost reduction. By age and family group, people aged 30 - 40 years and single-person households are the main consumption group. As a result of this study, it is necessary to establish marketing strategies for producers such as rational pricing, safety, taste promotion, and small-scale sales to extend the demand for Hanwoo beef in the younger generation to enhance the competitiveness of the domestic beef market.

Due to the high interests of image quality by consumers, the concerned market becomes more heated. Recent digital camera development tendency shows to perform the higher image quality to meet consumers demand of quality satisfaction. However it is hard to confirm that development of objective image quality performance means positive subjective image quality preference. And also, we cannot find out the previous researches concerned on correlation between objective and subjective image quality comparison. Therefore, it is necessary to analyze the consumers preferred images based on objective image quality performance. Throughout this paper, we analyze statistical correlation between the objective and subjective image quality assessment methods by using ISO standards. In these results, we try to find attributes that enhance image quality. We suggest not only to analyze and reflect on customers' preferences, but also to pursue the high quality image performance practically. We expect the results of this paper to positively influence product development.

This study would analyze the visual expression elements, including layout, color, picture and typography in the election posters with the five main candidates of the 19th Presidential Election as the targets of the analysis. This study analyzed the candidates' images in the election posters and conducted a survey of the visual expression elements survey by the age of the voters. As a result of the analysis, Presidential Candidate Moon Jae-in felt fresh, and Yoo Seung-min like Moon had high percentages in layout and color, highlighting his clean image. Hong Jun-pyo had the most diverse preferences by age, and Ahn Cheol-soo, who showed the most unprecedented poster, too, had diverse preferences by age. Shim Sang-jung, who emphasized her familiar image, had preferences for her visual expression elements by all age groups in the following order: layout, color, picture and typography. Therefore, in order to utilize the visual expressions of the election posters, effectively, it is necessary to clarify the messages that the candidates would claim. For this purpose, objective research should continue so that they can be further developed artistically and academically through broad understanding and analysis of the voters rather than subjective expressions.

Because the educational significance of reading activities for growing children is so great, the importance of reading cannot be overemphasized. While the reading volume of elementary school students in Korea is very high, as they go up to middle school, the reading volume falls rapidly. This study examined a more effective way to resolve this middle school reduction in reading volume. Middle school freshmen were surveyed on their reading habits and preferences in the sixth grade of elementary school, after which the groups were divided into two groups based on their averages; groups with high/low reading habits and groups with high/low reading preferences). Participants also wrote reading reports for six weeks, kept a record of the days of the week they read for more than 20 minutes, and noted down the time they read in minutes. It was found that 75% of participants did not read one book a week when in the sixth grade of elementary school and it was confirmed that reading many books and liking to read were elements that had different dimensions. For example, about 35% of the participants said they liked books but rarely read them. It was also confirmed that the reading habits formed in elementary school were a strong variable that affected the number of days that and the reading time of middle school students rather than the reading preferences formed in elementary school. This study concluded that a subjective attitude toward reading and actually reading were completely different problems, which suggested that 'habits' could have a greater influence than 'preferences' when performing tasks to achieve goals.

This study was to evaluate the taste of the wine assessment gap analysis to compare the taste of the wine intended for college student wine consumers and wine experts. Research analysis was carried out frequency analysis to the strength of the wine taste a difference in the intensity of the consistency review and wine for the wine flavor between the two groups. According to result, red wine, bitter and salty taste was perceived higher. For white wines are perceived sweetness of wine was sour and higher consumer groups. Body was found that wine experts perceive higher. The Second difficulty is when college student wine consumers selected wine got another show to the lack of information, lack of expertise, price, taste, the combination of food. Another wine on difficult points during the wine expert wine recommendations wine selection, price, prejudices then guest it showed a preference and communication, considering that the customer's budget, customer preferences, taste and aroma, the combination of the food and the customer response was configured. Although the criteria have different tastes for wine through college student wine consumers if future studies presented by symbolic reference to the wine tasting, can be self-objectification of subjective criteria subjective wine experts are wine consumers to take advantage of these data.

Quantitative evaluation of the sense of smell is done by the olfactory event-related potential (OERP) test. OERP consists of N1, P1, N2, P2, and P3, of which N1 and P1 latency are known to be affected by the concentration of odor stimuli associated with the pre-sensory phase and P2 and P3 are the stages at which odors are perceived and are known to change by subjective evaluation of the stimulus. The purpose of this study was to clarify the correlation between the expression of OERP and the subjective evaluation of the object on the fragrance stimulus using various fragrances. Therefore, the study examined the relative waveform power ratio, preference for each scent stimulus, and finally the amplitude and latency change of the components of OERP, N1 and P2. In contrast, it was found that the late P2 response waveform was an effective aroma stimulus recognition waveform in OERP compared to the initial response waveforms.

One of the main functions of packaging is promoting the products. Competitive markets demand that products appeal more to consumers in many perspectives. Other than its original purpose, which is protection, packaging has been tasked with implementing the emotional appeal of a product through unique shapes, textures, and visual designs. Understanding emotional appeals to consumer is a potential marketing strategy so that research have been done about techniques to visualize the design and print the specific textures. Especially, paper-like films are known as eco-friendly or emotional design and they are able to protect the products from oxygen or water vapor better than papers. In this study, paper-like films, which is printed with inks to have rougher surfaces, are analysed in terms of roughness, friction, imaging and sensory evaluation of subjective softness from consumers. Also, the prediction model was established with the correlation of the measured results and sensory panel test (SPT) of consumer preferences by touch. The results showed that the prediction of subjective texture preference was contributed by 63.9% for surface roughness and 36.1% for friction profile parameters. It confirmed that surface roughness characteristics should be prioritized to improve tactile preference for paper-like films.
