  • The heterofermentative Leuconostoc mesenteroides, which is propagated from the initial to the intermediate stage of Kimchi fermentation, produces organic acids and carbon dioxide to impart refreshment, weak acid taste to Kimchi. But owing to lactic acid production by the homofermentative Lactobacillus Plantarum, Kimchi finally reaches its acidified state. So, Leu. mesenteroides was isolated from Kimchi and identified and was improved by mutation for carbon dioxide production at low pH, and for the high total acceptability. We tested with a wild-type strain K-1 and its improved mutant strain M-10 of Leu. mesenteroides. The wild-type strain K-1 could grow in pH 4.2 at 30$\circ$C or 20$\circ$C, and in pH 5.0 at 10$\circ$C. But the mutant strain M-10 could grow in pH 3.3 at 10$\circ$C. In the respect of total acceptability, mutant strain M-10 inoculated Kimchi was ever better than any others. Mutant M-10 inoculated Kimchi prolonged the optimum ripening period of Kimchi up to two times as compared with the control group.

  • This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuza pyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.

  • The purpose of this study was to investigate the perception and preference for Korean Kimchi in Singapore. A questionnaire was answered by both male 236(43.0%) and female 313(57.0%) college students residing in Singapore. The results were as follows : the nationality of Kimchi as Korean was given by 86.9% of the participants, and 48.7% had eaten Kimchi. For their perceptions on Kimchi, the highest answer at a mean of 3.95 was 'Kimchi is a good side dish with cooked rice'. It was significantly different than 'Kimchi is delicious'(M=3.14, p<.05). In the evaluation of different kinds of Kimchi, taste was highest for anchovy dachi Kimchi(M=5.50) on the fourth day of fermentations, and overall acceptability was also highest for the anchovy dachi Kimchi(M=6.18) on the fourth day(p<.001). In the sensory evaluation by Kimchi use, the best taste was in the order of Kimchi Salad(M=6.10), Kimchi Bacon Roll(M=6.00) and Kimchi Croquette(M=5.67), and the order for overall acceptability was Kimchi Salad(M=6.10), Kimchi Bacon Roll(M=6.00) and Kimchi Croquette(M=5.92).

  • Objectives: It has been found that health promotion interventions are effective to decrease morbidity among older people. The acceptability of interventions are, however, still troublesome for achievement of efficacy of health promotion interventions. The current study examines the effects of age identity and attitude toward aging on the use of health promotion programs among older people. Methods: Data from the Survey of Living Conditions of Korean Older Persons were used. Logistic regression models were tested using a nationally representative sample of 9,461 community-dwelling older individuals who are 65 years old and over. Results: Older individuals who have younger age identity and more negative attitude toward aging were less likely to use health promotion programs, after adjusting the effects of other predisposing, enabling, and need factors such as demographic characteristics and personal health characteristics. Conclusions: Strategies for mitigating the possible effects of age identity and attitude toward aging on the acceptability of health promotion programs are also discussed.

  • It is generally known that children's development of 'gender schema' and 'gender role stereotype' has a positive relationship with the notion of 'gender role preference'. This study analyzed an unusual case focusing on the role playing of two brothers'. The elder brother, Hyoung-Gyoo, always preferred to take the female role, and he had a preference for feminine names like "Cordelia" whilst engaging in role playing situations. The brothers can be said to have crossed the border into the realm of intersexual role playing. The results revealed Hyoung-Gyoo's clear discrepancy between gender-related perceptions and reality, and showed his younger sibling Je-Gyoo's high level of acceptance towards his brother's extraordinary gender role preference. The results of this study can serve as a useful reference point for detailing unusual development from early childhood regarding 'opposite-gender-role seeking' characteristics.

  • From the point of breeding view for our future, 20 Korean varieties of red pepper for the contents of capsaicinoids, free amino acids, free fatty acids and organic acids with powder product and eating qualities were chosen, and the sensory properties of their water and ethanol extract were compared in order to investigate the influence of the composition of test components on sensory acceptability of Korean red pepper. The composition of taste components in red pepper powder varied wildly depending on the varieties; total capsaicinoids content variety from 0.029 to $0.913\%$, free sugar 8.45 to $20.2\%$, and organic acid 4.58 to $19.54\%$. Capsaicinoid contents especially dihydrocapsaicin content, were highly correlated with pungent taste of the methanol extract of red pepper power, but did not show significant relationship to the overall sensory acceptability. However, the components analyzed here and eating and processing qualities include high variations and future breeding sources.

  • Social commerce has a large impact on the emergence of the concept of society and individual lives that is recognized as one of the most important business areas in the Internet environment. A marketing agency, Trend Monitor (http://www.trendmonitor.co.kr), conducted a survey on social commerce usage and satisfaction level; subsequently, we used survey result data from 221 adult males and females for our research sample. Data analyses were conducted by reliability test, confirmatory factor analysis, t -test or one-way analysis of variance, and structural equation model (SEM) with IMB SPSS ver. 21.0 and ver. AMOS ver. 21.0. This study focused on multi-dimensional consumer innovativeness and found three elements of acceptability, competence, and distribution. Empirical verification through SEM presented data that suggests the three consumer innovativeness factors have a direct positive effect on social commerce that causes factors to indirectly affect satisfaction levels. This study indicated that the main consumption patterns in modern society take advantage of social commerce and satisfaction by improving a market economy to promote restoration. First, this study considers consumer innovativeness to have three factors. Secondly, research results help to understand relations between consumer innovativeness, use and satisfaction with social commerce that can help the social commerce industry establish effective market strategies through consumer innovativeness. The conclusion discusses implications for academic research and marketing strategies.
