High prices, overfishing, and contamination have limited the availability of natural caviar as a food product. We attempted to apply encapsulation by calcium-alginate gel membranes to caviar analog preparation in an effort to produce a high-quality replacement for natural caviar. Physical conditions of stirring speed $(X_1,\;rpm)$ and gelation time $(X_2,\;min)$ as the independent variables for gelation were optimized by response surface methodology. Sphericity $(Y_1,\;%)$, diameter $(Y_2,\;mm)$, membrane thickness $(Y_3,\;mm)$, rupture strength $(Y_4,\;g)$, and rupturing deformation $(Y_5,\;mm)$ were used as the dependent variables to compare characteristics of the capsules for caviar analogs with natural caviar. The values of the independent variables as evaluated by multiple response optimization were $X_1=-0.1271 (278 rpm) and $X_2=0.4436$ (12.2 min), respectively. Predicted values of the four dependent variables were $Y_1=97.7%,\;Y_2=2.97mm,\;Y_4=1,465g,\;and\;Y_5=1.15mm$. Membrane thickness $(Y_3)$ was eliminated from the dependent variables for multiple response optimization because it could not be measured with an image analyzer. The experimental values prepared under the optimal conditions for verification nearly coincided with the predicted values and satisfied the conditions of natural caviar.

This study was intended to present basic materials for the direction of product planning and marketing strategy to increase the market share of men's underwear. For this purpose, it attempted to classify the groups according to the benefit of pursuing men's underwear and analyze the differences in purchase behavior among the segmented groups. The specific purposes of the study were to investigate the purchase behavior of men's underwear, to segment the consumers into groups according to underwear benefits sought, to investigate the differences in purchase behavior among the groups, and to investigate the differences in demographics among the groups. The questionnaire was distributed to men aged the 20s to the 40s living in Seoul. A total of 297 questionnaires were used for the final analysis. As a result, the following findings were obtained. It was found that 84.8% of the respondents showed there was no favorite underwear brand. They showed the favorite color of translucent color, the favorite style of trunk and brief, the favorite post-processing of silver nano, deo processing, and the favorite material of charcoal. In purchasing men's underwear, the respondents showed a preference for simple image, and the discount store as the place of purchase. The results also showed that there were four groups of underwear benefits sought: sex appeal/individuality, comfort, practicality, and fashion/brand groups. In regard to the group differences, there were significant differences in underwear purchase motives, underwear preferences, store selection criteria, and demographics.

The purpose of the study is to determine how consumers perceive certification marks for agricultural products. The study examined three agricultural product certifications, such as the certification of environment-friendly agricultural products, Good Agricultural Procuts (GAP) certification mark, and United States Department of Agriculture (USDA) certification mark. A survey was utilized for data collection from adults over the age of 19 in November, 2013. A total of 390 questionnaires were distributed, and 300 of those were obtained for an analysis of the study. The results were as follows. First, consumers' awareness of, image of, and credibility on the agricultural products with the certification marks were not significantly different among the three certification marks except consumers' awareness. Second, consumers' purchase intentions for and willingness to pay for the agricultural products with the certification marks were not significantly different among the three certification marks. Third, these variables were not significantly different between buying group and non-buying group except consumers' awareness. Lastly, buying group and non-buying group were significantly different only in gender and marital status. The findings offer implications to the food and food service industry regarding consumers' purchase of certified agricultural products. Further, the study enforces the roles of food industry for environment.

This thesis suggested that the 'customized' marketing would be a new strategy in terms of a marketing in the digital media age under the circumstances where a form of marketing was evolving in accordance with the convergence of digital media. Because of the media environment due to an 'individualization', the strategy would meet an individual demand of a consumer in a rapidly changing environment. The best marketing to capture a 'customer's heart' is not a brand that first entered the market, but the one that is first settled in a customer's heart. If a differentiated interactive marketing strategy is equipped, it is possible to capture a completely new market space ad create a profit over several years. In the aspect of an effect of a digital marketing, first, a concept relating to an interaction between a consumer and a producer is important. Secondly, the important one is an empathy marketing which is an emotional marketing through a brand image beyond a product. Thirdly, the author studied an orally transmitted marketing effect through digital media.

In Honam province, the cultural prototype are largely unknown to the people, also the research on this subject are scarce, the artistic excellence, somewhat under evaluated, both in our country and internationally. It is imperative that we develop the modern design using this prototype. thereby apply it to many areas of cultural products. We should extend the dimension not only to the local festival but also to the mass production resulting in the commercial gains. The Unjusa Buddha festival for promoting the public relation would be greatly benefited by using the concept of the temple, the local prototype, by which we expect to create a ingenious textile design pattern, coinciding with the main purpose of this study. The ancient material around Unjusa come to be the subject of our textile design by way of selecting the most remarkable ones of heritage among the materials of Unjusa. In the long run, the harmonious contrast of both traditional and modern image were sought in this study. Designed patterns were edited using Adobe Photoshop CS3, a multi-purpose graphic program and were simulated in the towel for visual presentation. The design is of two kinds, the one is of the free style using combinations of reclining Buddha, stone Buddha, stone pagoda, and geometric patterns freely not to be standardized. The other one is mixing of lotus pattern, reclining Buddha, and geometric patterns. These designs were applied delicately on the towel, necktie and handkerchief, and the various colors were suggested by the 6 color ways. The brilliance of our traditional cultural property should be noted by these designs and I hope that this study would be a help to develop our cultural prototype and make a product of using the outstanding heritage.

We present and discuss the Tropopause Folding Turbulence Detection (TFTD) algorithm for the Korean Communication, Ocean, Meteorological Satellite (COMS) which is originally developed for the Tropopause Folding Turbulence Product (TFTP) from the Geostationary Operational Environmental Satellite (GOES)-R. The TFTD algorithm assumes that the tropopause folding is linked to the Clear Air Turbulence (CAT), and thereby the tropopause folding areas are detected from the rapid spatial gradients of the upper tropospheric specific humidity. The Layer Averaged Specific Humidity (LASH) is used to represent the upper tropospheric specific humidity calculated using COMS $6.7{\mu}m$ water vapor channel and ERA-interim reanalysis temperature at 300, 400, and 500 hPa. The comparison of LASH with the numerical model specific humidity shows a strong negative correlation of 80% or more. We apply the single threshold, which is determined from sensitivity analysis, for cloud-clearing to overcome strong gradient of LASH at the edge of clouds. The tropopause break lines are detected from the location of strong LASH-gradient using the Canny edge detection based on the image processing technique. The tropopause folding area is defined by expanding the break lines by 2-degree positive gradient direction. The validations of COMS TFTD is performed with Pilot Reports (PIREPs) filtered out Convective Induced Turbulence (CIT) from Dec 2013 to Nov 2014 over the South Korea. The score test shows 0.49 PODy (Probability of Detection 'Yes') and 0.64 PODn (Probability of Detection 'No'). Low POD results from various kinds of CAT reported from PIREPs and the characteristics of high sensitivity in edge detection algorithm.

This study is to develop cultural products based on 'Jeju Choga', which means the traditional houses in Jeju. For the product development, old literature review, field surveys, and consumer surveys were employed. Through old literatures and field surveys, the unique and visual characteristics of Jeju Choga were confirmed: A thatched roof with lattice pattern, a side wall and fences with porous stones, a 'Jungnang' serving as a gate, and a 'Pungchai' preventing strong sola radiation and 'Ollai' meaning a narrow street in front of the Choga. As a results of consumer survey conducted before the development of products, consumers highly recognized and associated Jeju Choga as Jeju representative image. The six basic patterns of Jeju Choga were drawn and eight textile designs were created through the repeated arrangements of the basic patterns. Using the created textile designs and digital printing method, the eleven new fabrics with the patterns of Jeju Choga were developed. The various kinds of ten bags and tow wallets made with the new fabrics. As a result of consumer evaluation for the twelve products made in this study, the scores of preference and purchase intention were above the average work for the most products of them. In particular, the preference and purchase intention of the square shoulder bag, the big-size shopper bag, and the small-size cross bag were very positively evaluated. Therefore, it is confirmed that Jeju Choga could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.
