유방암 발생률이 해마다 증가하여 그에 따라 유방 종양을 진단하는 검사인 조직검사의 횟수도 같이 증가하고 있다. 조직검사는 침습적 검사로써 환자들의 불안감과 감염, 출혈 등의 부작용이 발생하고 있다. 본 연구에서는 유방 병변 환자를 대상으로 회색조 초음파와 탄성초음파검사 모두 실시한 69명을 대상으로 회색조 초음파는 BI-RADS Category에 따라 분류하고, 탄성초음파검사는 횡파의 전파 속도를 환산하여 나타낸 kPa값을 Color overlay pattern으로 분류하였다. 민감도와 특이도의 합이 가장 높은 최적의 Cut-off value는 54.70 kPa로 나타났다. Color overlay pattern에서 Dark Blue 42명, Light blue ~ Red 27명으로 분류된 결과와 BI-RADS Category 분류 결과인 양성 40명, 악성 29명으로 분류된 결과가 유사하다. 따라서 Color overlay pattern에서 Dark Blue에 분류될 경우에는 양성, Light blue ~ Red에 분류될 경우에는 악성으로 의심할 수 있을 것으로 판단된다. 결론적으로 유방 탄성초음파는 무분별한 유방 조직검사의 횟수를 줄이고 양성종양과 악성종양을 구분하는데 획기적인 역할을 할 것으로 사료된다.

Color is one of the most important attributes determining the purchase of food products by consumers. Therefore, the purpose of this study was to identify consumer color preferences for songpyun, a traditional Korean rice cake, by a consumer acceptance test and using coated Pantone color chips. Color evaluation tools for the study were developed accordingly. From the results, the songpyun sample designated as product E was given the highest color acceptability score, and was 'slightly liked' (p<0.05). The color of product E was 'very pale red-purple'. All the evaluated pink-color songpyun products were based on this red-purple hue, however, they had differences in tone. The consumer panel favored a pale tone over a bright tone. The color concept for traditional songpyun within the pink color category was identified as 'very pale red-purple', using coated Pantone color chips. This result for the conceptual color preference was consistent with that of the consumer color acceptance test. Thus, color chips could be an effective tool when applied for color standardization in traditional foods production. From the overall results, it seems consumers are perceiving color trends and are willing to adapt to such changes in food applications.

This study comparatively analyzed the images and preference of lighting space using the emotion-based technique in order to effectively use it in clothing shops and fashion marketing. In terms of color temperature for light sources, 2,800K of lamp color, 6,500K of daylight color and 4,200K of white color were used. For the assessment, sensory evaluation technique was used. Then, the study found the followings: In terms of the image of lighting space by light source, different images were observed by light source with significant difference by the evaluation category. For factor analysis by the evaluation category, 7 factors were extracted. Among them, evaluation on lighting space was influenced by the following three images: modern space, elegant space and classical space. In particular, the modern space comprised of the following adjectives had the biggest effect on the assessment of the image of lighting space ('refreshing,' 'transparent,' 'bluish,' 'bright' and 'non-classical') (primary evaluation 30.13%). According to assessment on the preference of lighting space, the respondents' most favorite lighting space was 4,200K while their least favorable one was 6,500K in terms of color temperature. In terms of preference by the image of lighting space, they didn't like 'non-elegant' and 'non-beige' images even though they had the images of modern space. Therefore, it was confirmed that beige and elegant space images have an effect on the preference of lighting space.

Recent color plans in school buildings are made by experts through public offerings for prizes for designs etc in relatively many cases. But it is necessary to review if such color plans are actually well conform to students' emotions and what trend the color plans made as such have. Therefore, this study examined and analyzed the exterior colors of the school buildings planned by public offerings for prizes for designs and reviewed the result comparing to the color preferences of students that had already been studied to figure out the differences between existing theories and the realities. And it was examined what differences were existing in the trends of color plans and color images examined between each of school levels. The result of the study compared to theories is as follows. First, when the color distributions were reviewed for each school level, it could be confirmed that the overall distributions moved from Y category to B category and whereas warm colors were more widely distributed and the number of colors were greater compared to cold colors in case of elementary schools, the distributions of warm colors gradually decreased as school level moves to high schools. Second, the color use distributions of elementary school students were revealed to be more diversified than middle and high school students and also the number of colors used was 9.5 in average in elementary school and middle schools and high schools were similar to each other with average 5.86 colors in middle schools and 6.33 colors in high schools showing a little differences in color use distributions among school levels of elementary schools, middle schools and high schools. Third, in case of elementary schools, except main colors, both of subsidiary colors and emphasizing colors had the distributions of warm colors of R, YR, Y categories and cold colors of B, PB categories and this is also consistent with the results of existing research results indicating that low grade students prefor for warm colors and high grade students prefer for cold colors. Fourth, in case of middle schools and high schools, although the distributions of warm colors decreased, the distributions of warm colors and cold colors were revealed to be similar. This is considered to be consistent with the existing research results indicating that girl students prefer for warm colors even if their ages go up. Fifth, as for the images of main colors, subsidiary colors and emphasizing colors resulted from the comparisons by solid color Image Scales and adjective Image Scales, first, in case of main colors, natural images or clear images appeared the most in all of elementary schools, middle schools and high schools indicating that basically calmness is emphasized with soft images rather than hard images and static images rather than dynamic images. Also, in case of subsidiary colors or emphasizing colors, cheerful images or splendid images are also seen to decrease as school level goes from elementary schools to high schools in adjective Image Scales and this is considered to reflect the color sentiment differences between children and juveniles based on ages.

As a designer, Rei Kawakubo had become one of the most influential woman of the 20th century. Comme des Garçons, which means "like boys"-what women in the early 1980s were least supposed to be-expressed criticism of the prevailing social construct of women and, importantly, of the very concept of fashion. The press had a field day with the so-called post Hiroshima look, with its aesthetic of destruction, poverty, and hunger and with its depressing mood engendered by the use of the color black. This research divided the change of design transition on Kawakubo's fashion by the three categories. The first category was experimental pattern, the second category was esthetics of omission and the third category was innovation of body consciousness. The costume messages through these design works of Kawakubo could summarize 5 items, punk sprit, beyond sex, reality, proposal of new body consciousness and representation of black.

This study evaluated the effect of freezing rate on the quality characteristics of pork loin to establish an objective standard for rapid freezing. To generate various freezing rates, three air flow rates (0, 1.5, and 3.0 m/s) were applied under three freezing temperatures (-20℃, -30℃, and -40℃). Based on the results, freezing rates ranged from 0.26-1.42 cm/h and were graded by three categories, i.e, slow (category I, >0.4 cm/h), intermediate (category II, 0.6-0.7 cm/h) and rapid freezing (category III, >0.96 cm/h). Both temperature and the air flow rate influenced the freezing rate, and the freezing rate affected the ice crystal size and shear force in pork loin. However, the air flow rate did not affect thawing loss, drip loss or the color of pork loins. In the comparison of freezing rates, pork belonging to category II did not show a clear difference in quality parameters from pork in category I. Furthermore, pork in category III showed fresh meat-like qualities, and the quality characteristics were clearly distinct from those of category I. Although the current standard for rapid freezing rate is 0.5 cm/h, this study suggested that 0.96 cm/h is the lowest freezing rate for achieving meat quality distinguishable from that achieved with conventional freezing, and further increasing the freezing rate did not provide advantages from an energy consumption perspective.

This study researched about gender color preference as basic data for color application of fashion shop Facade. A HUE TONE system from V(vivid) to DK(dark) was used based on 10 colors of the IRI-120 color chart, color preference according to gender was investigated through a survey on males and females of over teenage years, and it was analyzed and presented as a color matching chart. And it was suggested as a color guideline through comprehensive analysis. Few definitions can be given through the results of this study. First, the preference degree according to gender was similar but different senses were shown visually even though the same adjective expressive vocabulary of a color image was suggested. This means there is an unchanging basic conservative disposition that males and females do not have and therefore they infer different ideas according to various environments and factors. Second, females showed more sensitive response to colors than males in the gender color preference result, which confirmed the deviation of each color group that is characteristically preferred according to a category. Third, high preferred color matches according to gender were shown for each vocabulary in various senses such as similar color matching, complementary color matching, separation color matching, and accent color matching. A universal empirical theory by general sensibility was obtained as the purpose of this study. This study suggested securement of a color design planning as basic data and the extent of usability by quantitatively showing the order of priority through the survey and analysis. Thus, the results of this study will be a great help as basic data for invigoration and commercialization of a color planning for designers and users.
