  • 본 연구에서는 연령증가에 따라 운전에 필요한 신체적, 인지적 능력의 변화가 어떻게 나타나는지 설문을 통해 분석하고, 이것이 교통안전 시설물(신호기, 노면표시, 도로표지판)의 필요성 및 적정성을 평가하는 것과 어떤 관계가 있는 지 살펴보고자 하였다. 이를 위해 20세 이상 운전면허 소지자를 대상으로 5개 권역, 500명을 대상으로 설문조사를 실시하여 이를 분석하였다. 운전능력에 대한 자기평가 점수는 종합적 능력, 개별능력(시력, 청력, 색채식별 등) 모두 연령이 증가함에 따라 점수가 낮아지는 것으로 분석되었다. 특히 시력은 연령증가에 따른 감소폭이 크고, 절대적인 평균점수가 다른 항목에 비하여 낮게 나타났다. 시력의 경우 타 신체적, 인지적 능력에 비해 운전 중 기능의 저하에 따른 체감도가 크기 때문인 것으로 판단된다. 설문결과에 따른 분류분석을 통해서는 신체적, 인지적 기능의 저하가 시작되는 연령이 기존의 고령운전자로 판단하는 65세 보다 낮은 48세로 분석되었다. 이것은 연령증가에 따른 기능 저하로 인한 영향을 받는 운전자가 그렇지 않은 운전자보다 더 많다는 것을 의미한다. 또한 시설물에 대한 필요성 인식에 대한 평가 역시 운전능력에서 차이를 나타내는 연령대에서 인식의 차이가 있을 것으로 분석되었다.

  • The knowledge base on emotional information is one of the key elements in the implementation of emotion retrieval systems for contents design of Mobile devices. This study proposed a new approach to the knowledge base implementation by automatically extracting color components from full-color images. In this study, the validity of the proposed method was empirically tested. Database was developed using 100 interior images as visual stimuli and a total of 48 subjects participated in the experiment. In order to test the reliability of the proposed 'emotional information knowledge base', firstly 'recall ratio' that refers to frequencies of correct images from the retrieved images was derived. Secondly, correlation Analysis was performed to compare the ratings by the subjects to what the system calculated. Finally, the rating comparison was used to run a paired-sample t-test. The analysis demonstrated satisfactory recall ration of 62.1%. Also, a significant positive correlation (p<.01) was observed from all the emotion keywords. The paired Sample t-test found that all the emotion keywords except "casual" retrieved the images in the order from more relevant to less relevant images and the difference was statistically significant (t(9)=5.528, p<.05). Findings of this study support that the proposed 'emotional information knowledge base' established only with color information automatically extracted from images can be effectively used for such visual stimuli search tasks as commercial interior images.

  • This study investigated the consumption tendency and awareness of paprika in order to expand and promote the consumption of Capsicum annuum L. The research investigated the relationship of preference and loyalty based on emotional response of paprika according to the semantic differential scale. The survey was conducted from January to February 2022 using a random sampling method targeting 155 general people, and a total of 142 questionnaires were analyzed excluding 13 wrong answers. The nine items on the awareness of paprika showed to be consisted of three factors such as 'Food taste', 'Usability', and 'Economics' by factor analysis. Regarding to the awareness of paprika the positive answer that 'I think paprika is good for health' among the nine questions was the highest at 92.3%. In the preference aspect of shape, blocky type had the highest preference for the shape of paprika, followed by mini and conical types in order of preference (p < 0.001). As for color preference, yellow paprika was the most preferred, followed by orange, red, and green, showing statistical significance. The emotional response of paprika by paprika image showed a statistically significant difference in the four colors. The words such as 'bright', 'clean', and 'spirited' appeared as representative emotional vocabulary for paprika. Multiple regression analysis was performed to examine the effect of paprika on the three factors of awareness, preference, and loyalty due to the quality of life. As a result, the higher the paprika preference and quality of life, and the higher the taste and availability factors, the higher the paprika awareness and loyalty. As the variable that has the most influence on the loyalty of the survey respondents, preference was found to have the highest explanatory power at 43%. From these results, it was judged as a very important factor in the survey on the shape and color preference of paprika. Therefore, the recent increase in awareness that paprika is good for health is thought to act as a positive factor in revitalizing the domestic market and increasing consumption of paprika in the future. Also, among the three types of paprika, the yellow blunt type showed the highest preference. Therefore, in order to produce and promote this type of paprika, it is also important to increase the cultivation to suit the purchasing propensity of consumers.

  • Due to the development of modern society, desire for residence is not merely for the purpose of habitation. It's also used to represent the joy of living, the resident's emotional expressions, and social status. In order to express such desires, one of the most important factors used to portray them visually is the usage of color. When apartments are constructed, model houses are created to show potential tenants a sample house. The color scheme of those sample houses have been changed in accordance to the transition in the eras. Since 2000, construction companies have created their own apartment brand in order to create their own signature image. To achieve this signature image, one can alter the surface level and use other materials, and colors. I have researched the usage of colors out of the above. The criteria that need to be fulfilled to be a subject for my research are in the top 5 construction companies of the year 2010, within the metropolitan area, and open after 2009. As the result, all construction companies used colors Y and YR. An as accent colors on props such furniture and curtains, they used colors P, PB, and R. They were differences in color tones in each construction company and as the square footage increase, they used color contrasts. Hillstate and Raemian used darker shades in the larger houses. But the color tones YR and Y were used in all houses regardless of their size. E-world, Xi, and Prugio showed differences in shade and tone of colors regardless of size but rather depending on the locations of the apartments.

  • Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices.

  • Color, an important visual cue, can cross-modally affect odor association and odor quality identification Here, this research investigates aspects of the cross-modal associations between color and fragrance in greater depth, delving into the topic of whether the degree-of-association of fragrances with hue and tone of colors varies systematically. For 33 color stimuli (10 hues, 3 tones, and 3 achromatic colors), 67 subjects judged the degree-of-association of four typical fragrance families (fresh, floral, oriental, and woody) on a 7-point scale. The statistical analysis showed that fragrance associations of the all families had characteristic distributions across ten hues of the color stimuli. The cross-modal relationship between color tone (especially, lightness attribute) and fragrance association appeared to be dimensional (e.g. a positive linear relationship between the floral family and the lightness). More specifically, as colors became warmer and brighter, the associated floral scents were stronger, while the woody scents was less associated. Brighter or more vivid cool colors were associated with stronger fresh scents. These findings confirm the systematic existence of synthetic interactions between vision and olfaction in perfumery.

  • This study is intended to formulate the issues through the status analysis and image evaluation for each street on the basis of colors for the outdoor advertisements for part of street side in the oldest downtown for its construction year. Analysing the business type of the street side, it displays the identity of the fashion business area and the color status shown on the outdoor advertisement did not consider the harmony on the other business type and building improvements that it displays chaotic street views in overall. Status of color for the outdoor advertisement compared and analyzed for each street-side to be analyzed with high color contrast with the building structure and outdoor advertisements than the Street B side where there are many businesses of fashion sundries and fashion clothes to form more complicated street scenery visually for the Street A side. The color combination principle of building structure and outdoor advertisement was shown to be the factor for the contrasting unity and diversity. In order not to stimulate this visual confusion, the colors of outdoor advertisement has to be applied on the basis of the color guideline based on the color combination principle of outdoor advertisement and building structure to have the aesthetic harmony overall. As a result of analysis using the KJ method, the present image of the old downtown area was shown with the adjective vocabularies of "complicated", "out-dated", "chaotic", "disorganized", "dirty", "suffocating", and "unilateral", and its image to strive for would be in a total of 6 adjective vocabularies of "well-arranged", "young", "dynamic", "sophisticated", "personable" and "neat", and it has presented the basic foundation of color guideline of outdoor advertisement fit for its image.

  • The objectives of this study were to find the relationship between the olfactory sense such as perfume and sense of sight and how it affects the sensibility based on the fact that ,senses are compound feeling from detective parts of human body. First, to build the emotional rate stale we selected the 19 pairs of adjective from the previous studies that overlaps smell, color, and clothes and added one pairs of related clause. Then each pair was divided into 7 level of emotional stage. In the experiment by the selected 15 man and woman from the visual design major student of Hong-ick Univ each student was given floral, jasmin, lavender, papaya and asked them to pick one color from I.R.I Hue & Tone chart for each smell. Then, analyzed the emotional rating of selected color for given smell. The emotional structure of smell and color consists five parts; 'Esthetics', 'Romance', 'Character', 'Intensity', 'Nature', There were significant differences in frequencies of selected colors for each given smell and gender difference also affected the color selected. Average value of emotional rating scale of smell and color was ,similar to the results from previous studies on relationship between smell and emotion.

  • The Hahn double 15 hue test is used for social and vacational aptitude test to separate strongly and mildly affected subjects among the colour vision defective persons, detected using colour vision test. However, the assessment of colour vision defect type and severity is based on the hue confusions which are represented diagrammatically on Hahn double 15 hue score sheet, this qualitative assessment of the test results have not provide a numerical score suitable for methematical analysis. This paper presented a new proposal for quantitatively scoring the Hahn double 15 hue test based on those hue confusions made by the subject. With this program large numbers of double 15 hue test results can be processed easily and rapidly, and program helps to compare the severity of specific type colour vision defect and monitor acquired colour vision defect which has various disease process, continuously.

  • To investigate Fusarium mycotoxin contamination in rice samples from rice processing complexes (RPCs), paddy rice and rice-milling products such as husks, brown rice, blue-tinged rice, broken rice, rice bran, discolored rice, and polished rice were collected from nationwide in 2012. Three hundred seventy one samples of rice and its by-products were analyzed for three trichothethenes including nivalenol (NIV), deoxynivalenol (DON), and zearalenone (ZEA) by LC/MS. Discolored rice samples were found to have the highest contamination of DON, NIV or ZEA, followed by broken rice. Polished rice samples were largely free from mycotoxins, except three samples which were contaminated with NIV or DON at safety level. The rice byproduct samples were contaminated at higher level and frequencies than polished rice samples.
