  • Objectives: The purpose of this study was to compare and analyze the results of salty taste assessment, dietary attitudes, and dietary behaviors among adult and senior women by region and by age. The results generated from this was expected to provide fundamental data for implementing a nationwide salt reduction education program. Methods: The salty taste assessment tool was applied to 4,064 subjects from 15 areas in Korea. Also, a survey of dietary attitude and dietary behavior related to salt intake was conducted for all subjects participated in this study. Results: The salty taste assessment scores by region and by age were the lowest in capital (p < 0.01) and was highest among the 70+ year age group (p < 0.01). The dietary attitude scores and dietary behavior scores showed that Gyeongsang was the highest (p < 0.001) and the capital was the lowest. The dietary attitude scores were highest at 20&30's followed by 40's and 70's group (p < 0.001). Dietary behavior scores showed that 20's~30's and 40's groups were higher than the other age groups (p < 0.001). The score of 'I like kimchi' was $3.46{\pm}0.88$, which was the highest among 10 dietary behavior questions. The score of 'I eat a lot of kimchi' was $3.30{\pm}0.90$, which was the highest among 10 dietary behavior questions related to salt intake. The scores of salty taste assessment had significant positive correlations between the scores of dietary attitude (p < 0.001), dietary behavior (p < 0.001) and self-awareness (p < 0.001). Conclusions: Based on the results of salty taste assessment, we observed a tendency that older people and regions except the capital had higher preference for salty taste. Our results suggested the necessity for a nationwide salty reduction education program tailored for regions and for different age groups.

  • The purpose of this study is to determine potential effectiveness of sourdough starter powder (made of Korean wheat flour) in the quality characteristics of bread and in the substitution effect of a dough improver in bread baking. The bread containing sourdough starter powder was considered to be most suitable for making sourdough bread. As a result, SP 10 showed the best fermentation rate and the highest volume and specific volume. In sensory testing, SP 10 was most preferable among others. According to experimental comparison between optimal addition ratio of SP 10 and other sourdough starter powder products available in Korean domestic market, SI had the highest fermentation rate, highest volume and specific volume. Analysis of texture showed that SI was soft with the lowest hardness and the highest elasticity. Sensory test showed that SI was most preferable of all, and SP 10 was more preferable than BP. It was concluded that SP 10 was not less preferable in the aspect of preference at sensory test than other products. Hence, it is expected that sourdough starter powder made of Korean wheat flour will be possibly more popular and effective in replacing some portion of dough improver of baking.

  • The purpose of this study was to compare the differences of the vocational values and the career orientation of science between middle school scientifically gifted students and non-gifted students. The subjects were 85 middle school scientifically gifted students and 139 middle school non-gifted students. For this purpose, the questionnaires about vocational values and science career orientation were administered. The results of this study were as follows: First, the vocational values between two groups were significantly different in 'diversity', 'reward', 'social recognition' and 'autonomy' among all 11 domains. 'Diversity' and 'autonomy' showed the highest scores for scientifically gifted students. On the other hand, for the non-gifted students, 'reward' and 'social recognition' showed the highest scores. Second, the grand mean of the science career orientation between two groups showed significant differences. The average of scientifically gifted students was significantly higher than that of the non-gifted students in all four sub-domains. Third, the main effect of the vocational values according to gender did not exist, but there were main effects, including diversity, reward, stability, social recognition and autonomy, between two groups. There was no interaction effect between group and gender in the vocational values. Fourth, there were interaction effects between group and gender in the science career orientation. The main effects existed in four sub-domains of science career orientation. However, according to gender, the main effect existed in the sub-domain 'job preference for science' between the male students and the female students.

  • This paper mainly focuses on the Korean Folk Village and Beijing Si-He-Yuan, according to the color theory of hue, value and chroma of Munsell color system to demonstrates the similarities and differences of the traditional upper-class housing between South Korea and China. As the neighboring countries sharing very similar culture and philosophy which owe to the continual communications between China and Korea in the history. The Obangsaek which is derived from the thought of five-elements profoundly and deeply impact on the color selection of traditional housing in both countries. According to the quantitative analysis of photographs, it was found that: 1. The commonly used colors in Korea are Y, YR and neutral color, but in China, people usually used R and GY, especially the high chroma red in Beijing Si-He-Yuan was used as a symbolic color. 2. The chroma preference of traditional housing reveals that people in China used to apply the polychrome and various brightness, on the contrary, the color of low chroma and high lightness were used to be applied in Korea which can give the sense of simplicity and tranquility. 3. Red, one of the Obangsaek affects the color characteristic of Beijing Si-He-Yuan critically but scarcely impact on the color characteristic of Korean Folk Village.

  • Background: The aim of this work was the comparison between the carcass and the meat ewes of the regional Traditional market and the Islamic religious (Halal) market. Methods: Thirty and 20 at the end of career traditional market and Halal market ewes were slaughtered following the EC (European Council, 2009) animal welfare guidelines. Live weight of ewes was taken and dressing percentage of carcasses was calculated. On every carcass zoometric measurement and the evaluation trough the EU grid rules were performed. On the Musculus longissimus thoracis of 12 Traditional market carcasses and 11 Halal market carcasses the physical-chemical and nutritional analysis were performed. Consumer tests for liking meat ewe were performed in order to find consumer's preference level for Traditional and Halal markets ewe meat. Considering as fixed factor the ewe meat market (Traditional and Halal), results were submitted to oneway Analysis of Variance (ANOVA) and to Principal Component Analysis (PCA). Results: The Halal market ewes have shown lower dressing percentages ($42.91{\pm}0.82$ vs $46.42{\pm}0.69$) and lower conformation score ($4.5{\pm}0.5$ vs $7.8{\pm}0.4$). The Halal market meat showed higher cooking loss in oven ($37.83{\pm}1.20$ vs $32.03{\pm}1.15%$), lesser Chroma value ($18.63{\pm}0.70$ vs $21.84{\pm}0.67$), and lesser Hue angle value ($0.26{\pm}0.02$ vs $0.34{\pm}0.02$). This product had also lower fat percentage ($4.2{\pm}0.4$ vs $7.09{\pm}0.4$). The traditional market meat had higher percentage in monounsatured fatty acids (MUFA) ($43.84{\pm}1.05$ vs $38.22{\pm}1.10$), while the Halal market meat had higher percentage in ${\omega}3$ poliunsatured fatty acids (PUFA) ($5.04{\pm}0.42$ vs $3.60{\pm}0.40$). The consumer test showed as the ewe meat was appreciate by the consumers. Conclusions: Both meat typologies have shown good nutritional characteristics. The traditional market meat had higher MUFA composition, and a better MUFA/satured fatty acids (SFA) ratio, while the Halal market meat had higher PUFA composition. These results were also supported by the PCA. The consumers preferred the traditional market meat.

  • The present study aimed to understand the taste of literati appearing in the Korean-Chinese garden by comparing "Yanghwasorok(養花小錄)" and "Zhangwuzhi(長物志)", which are one of the representative gardens in Korea and China. The main subject of comparison is plants; the research results are as follows. First, Gang Hui-an stated that the ultimate purpose of growing and appreciating the gardening plants is the completion of oneself, while Wen Zhen-heng(文震亨) used gardening plants as a means to practice a life of reclusiveness(隱逸). Second, Gang Hui-an claimed that growing plants is human's cultivation of virtue on the basis of Confucian view's gaining knowledge by the study of things(格物致知), whereas Wen Zhen-heng realized the taste of 'elegance(雅趣)' through form of plants or planting method. Third, although plant preference of literati of both countries is similar in many parts, there is a slight difference for putting gardening plants in pots and appreciating them. For example, even for selecting or placing pots, simplicity and lightness are characteristically reflected from Gang Hui-an while splendor and refinedness are characteristically shown from Wen Zhen-heng. Moreover, in light of the taste of appreciation of literati of the Song Dynasty(宋代), which is a sample of literati spirit, Gang Hui-an inherited the inner world of the spirit whereas Wen Zhen-heng expressed 'literati-ness' in visual images.
