This paper compares a cross-cultural and gender differences and similarities about consumer ethical perceptions and behaviors, and ethical ideologies between Korean and the US college students. It also examines the relationships between consumers' ethical perceptions and behaviors, and the relationships between consumer ethics and ethical ideologies. This research provides some evidence that supports the premise that consumer ethics is influenced to an extent by consumers' nationality and gender. The differences are not universal, however, and could perhaps be described as situational. The American college consumers were found to be more idealistic and relativistic than the Korean college consumers. But the differences were minor. The American male college consumers were found to be more idealistic than the American female college consumers. The ethical consumer groups were found to be more idealistic and less relativistic than were the unethical consumer groups. Perceptions were positively related to behaviors in the consumer ethics. But the magnitude of impacts is different between the nations and in the dimensions of consumer ethics.
청소년소비자의 외모와 능력에 대한 만족과 평가 및 자아 존중감
서정희,백재화,김효철 울산대학교 2004 생활과학논문집 Vol.5 No.2
이 논문은 울산광역시에 소재 중·고등학교에 다니는 청소년 소비자가 자신의 외모와 능력에 대하여 얼마나 만족하고 있으며, 자신과 다른 사람이 어떻게 평가하고 있는지, 그리고 자신의 외모와 능력에 대한 만족도와 자신과 타인의 평가 및 자아존중감이 어떠한 상관관계를 가지고 있는지 알아보았다. 외모에 대한 만족도는 체중과 신장에 따라 의미 있는 차이를 보였고, 외모에 대한 자신의 평가는 체중, 신장, 용돈 및 아버지의 직업에 따라 의미있는 차이를 보였다. 외모에 대한 타인의 평가는 신장, 용돈 및 월평균가계소득에 따라 의미 있는 차이를 보였다. 능력에 대한 만족도는 체중과 아버지의 교육수준에 따라 의미 있는 차이를 보였고, 능력에 대한 자신의 평가는 신장, 월평균 가계소득 및 아버지의 교육수준에 따라 의미 있는 차이를 보였다. 능력에 대한 타인의 평가는 신장, 월평균 가계소득 및 어머니의 교육수준에 따라 의미 있는 차이를 보였다. 외모와 능력에 대한 만족도, 자신과 타인의 평가 및 자아 존중감간에는 모두 의미 있는 양의 상관관계가 나타났다. The objectives of this research were to investigate the level of appearance satisfaction, competency evaluation of respondents and others, and self esteem, the correlation of appearance satisfaction, competency evaluation of respondents and others, and self esteem. There were significant differences in the level of appearance satisfaction according to sex, weights and father's education. There were significant differences in the level of appearance evaluation of respondents according to sex, weights, allowance, and father's occupations. There were significant differences in the level of appearance evaluation of others according to heights, allowance, and monthly household income. There were significant differences in the level of competency satisfaction according to sex, weights and father's education. There were significant differences in the level of competency evaluation of respondents according to sex, weights, monthly household income and father's education. There were significant differences in the level of competency evaluation of others according to sex, heights, monthly household income and mother's education. appearance satisfaction, competency evaluation of respondents and others, and self esteem were positively correlated.
Antioxidant and Anti-inflammatory Activities of Butanol Extract of Melaleuca leucadendron L.
서정희,윤정미 한국식품영양과학회 2012 Preventive Nutrition and Food Science Vol.17 No.1
Melaleuca leucadendron L. has been used as a tranquilizing, sedating, evil-dispelling and pain-relieving agent. We examined the effects of M. leucadendron L. extracts on oxidative stress and inflammation. M. leucadendron L. was extracted with methanol (MeOH) and then fractionated with chloroform (CHCl3) and butanol (BuOH). Antioxidant activity of the MeOH extract and BuOH fraction were higher than that of both α-tocopherol and butyrated hydroxytoluene (BHT). Total phenol content in the extracts of M. leucadendron L., especially the BuOH fraction, well correlated with the antioxidant activity. The anti-inflammatory activity of BuOH extracts were investigated by lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production, and cyclooxygenase-2 (COX-2) expression in RAW 264.7 macrophages. The BuOH fraction significantly inhibited LPS-induced NO and PGE2 production. Furthermore, BuOH extract of M. leucadendron L. inhibited the expression of COX-2 and iNOS protein without an appreciable cytotoxic effect on RAW264.7 cells. The extract of M. leucadendron L. also suppressed the phosphorylation of inhibitor κBα (IκBα) and its degradation associated with nuclear factor-κB (NF-κB) activation. Furthermore, BuOH fraction inhibited LPS-induced NF-κB transcriptional activity in a dose-dependent manner. These results suggested that M. leucadendron L. could be useful as a natural antioxidant and anti-inflammatory resource.
