The present study was conducted to evaluate the anti-inflammatory and anti-arthritic effects of fermented Achyranthes japonica (Miq.) Nakai extract (FAJE). The FAJE was effective in nitrogen oxide (NO) scavenging in RAW264.7 cells. In the case of experimental Sprague Dawley (SD) rats injected with monosodium iodoacetate (MIA), the levels of $TNF-{\alpha}$ and $IL-1{\beta}$ in blood increased in the osteoarthritis-induced group while decreasing in the group administered with FAJE. In addition, MMP-2 and MMP-9 in cartilage tissues increased in the osteoarthritis-induced group, but decreased in the group treated with FAJE. Cartilage examination indicated that the osteoarthritis-induced group exhibited cartilage erosion and cell degeneration, but in the FAJE administered group the tissue, conditions were recovered and cartilage proteoglycan was increased. Therefore, FAJE clearly showed anti-inflammatory effects and this suggests it is effective for recovery from osteoarthritis induced by MIA.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

The purpose of this study was to analyze the determinants affecting the consumer-brand relationship quality (CBRQ) in the fast food restaurant. The questionnaires were distributed to 250 students in the K University located in Masan, who were sampled by convenience-sampling method from December, 6 to 14, 2004. The 246 questionnaires were responded, and 12 unusable questionnaires were excluded, then 234 were used for the final analysis (response rate: 93.7%). SPSS (12.0) was used for the statistical analysis. The result of this study showed that the CBRQ of low monthly income group was significantly lower than that of high monthly income group (p < .05), and the CBRQ of more frequent visiting group was significantly higher than that of less frequent visiting group (p < .001). The CBRQ of group who spend less than 30 minutes on their visiting the fast food restaurant was lower than that of group who spend more than 30 minutes (p < .01). As a conclusion, the operators in the fast food restaurant should focus on the concentrated marketing strategy for the frequent-visiting customers who had a strong quality of consumer-brand relationship in order to increase sales volume, and at the same time they should try to make marketing strategy to induce the less frequent-visiting customers who had less strong consumer-brand relationship quality to their restaurants in order to strengthen quality of consumer-brand relationship, which would be resulted to lead them to their restaurant more frequently.

The differences in food consumption between highly educated, married, unemployed and employed women were analyzed by food group and common food item intake, DDS (dietary diversity score), and DVS (dietary variety score) & DVSS (dietary variety score including condiment). In food group intake, the total amount of food intake of the unemployed women (1,554.0 g) were significantly higher than those of the employed (1,477.9 g), while the amount of food from fungi and mushrooms (4.2 g), seaweeds (2.4 g), and fish and shellfish (60.5 g) of the unemployed women was significantly lower than those of the employed. And the amount of meat, poultry and their products (102.8 g), eggs (29.9 g), and animal oil and fats (4.0 g) was significantly higher than those of the employed. Moreover, the common food items of the unemployed women were ranked as eggs (29.7 g), pork (28.9 g), chicken (27.2 g), and beef (26.7 g) at 7, 8, 9, and 10, respectively. When counting the major food groups consumed, DDS=4 has the highest proportion in both groups (unemployed 47.4%, employed 49.1 %). In case of the subjects who had not consumed one particular food group in DDS=4, dairy group was the first (83%), followed by fruit, meat, and vegetables. This order is same in other DDS levels. In dietary variety score (DVS & DVSS), the average number of foods consumed per day of employed women was higher than those of the unemployed. The level of DVSS in the employed women (31.9), especially, is significantly higher than in the unemployed women (30.6). Consequently, highly educated women should pay more attention to increasing dairy intake, and they have need of various foods, over thirty foods without condiments in their diet every day. In addition, encouraging unemployed women to have a nutritionally balanced diet, and offering nutrition education and guidance, such as appropriate choices about animal foods, are needed.

Objectives: The study aims to examine the variation over roughly the past 10 years (from 2008 to 2018) in the estimated daily dietary Pb intake (Pb-D) based on the variations of daily intake amount and Pb content in respective food groups. The following factors were considered: (1) variation of estimated value of Pb-D, (2) Pb contents in each food group and (3) the most influential food group for dietary Pb intake. Methods: Estimated values of Pb-D were taken from food consumption by the food groups reported in the Korean National Health and Nutrition Survey and the Pb content of each food group as reported in 19 previous publications. Variation from 2008 to 2018 of Pb intake was calculated from daily intake amount and Pb content in each food group. Results: The survey showed that main Pb intake sources were the food groups 'meats and poultry' and 'fish and shellfish'. These food groups showed gradually increased Pb exposure from 2008 to 2018. Estimated daily Pb intake was 42.18 to 57.68 ㎍/day for men and 30.97 to 42.54 ㎍/day for women. Both men and women showed slightly increased dietary Pb intake from 2008 to 2018. The food groups 'meats and poultry' and 'fish and shellfish' proved the highest Pb intake food groups. Estimated Pb intake from 'meats and poultry' was 8.47 to 12.98 ㎍/day and that of 'fish and shellfish' was 5.63 to 10.10 ㎍/day. Conclusion: Over the past ten years, daily Pb intake has slightly increased in men and women. The food groups 'meats and poultry' and 'fish and shellfish' might be the main variation factors of Pb intake.

The purpose of this study was to evaluate the sodium-related dietary attitudes, behaviors, and nutritional knowledge in university students according to the practice of dietary guidelines for Koreans established by the Ministry of Health and Welfare, Republic of Korea. Based on the total practice score related to the dietary guidelines (PDG), we classified subjects into a "low practice of the dietary guidelines (LPDG)" group (n=94, male=43, female=51) (total score of PDG ${\leq}13$) and a "high practice of the dietary guidelines (HPDG)" group (n=56, male=32, female=24) (total score of PDG >13). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using a questionnaire. The LPDG group had more subjects who were breakfast skippers (p<0.001) compared to the HPDG group. The LPDG group (31.26) had a significantly lower score in terms of salt-related dietary attitudes compared to the HPDG group (33.77) (p=0.0042). The score for salt-related dietary attitudes was significantly higher in the HPDG (32.52) group than in the LPDG (29.91) group (p=0.0041). There was no significant difference in the total score for salt-related nutrition knowledge between the groups. The correlation analysis indicated that the dietary guidelines practice score had a positive correlation with the salt-related dietary attitude score (r=0.3593, p<0.0001) and the dietary attitude score (r=0.3443, p<0.0001) after adjustments for sex. These results show that the degree of adherence to the dietary guidelines for adults may be related to sodium-related dietary attitudes, behaviors, and nutrition knowledge.

The purpose of this study was to analyze the food-related lifestyle choices of female baby boomers and to investigate variables regarding home meal replacement (HMR) buying behaviors and future needs. This study was conducted on 358 female baby boomers 53 years of age living in Gyeonggi and near Seoul. Out of 420 distributed questionnaires, 358 were returned and used for analysis (response rate: 85.2%). As a result of cluster analysis, three groups were identified based on the food-related lifestyles : a value-seeking group, a convenience-seeking group, and a health-seeking group. Among the three groups, there were significant differences in two socio-demographic characteristics, education level (p<0.05) and regular exercise (p<0.01), and in several health- and food-related habits, type of breakfast (p<0.01), type of dinner (p<0.05), dinner details (p<0.05), frequency of eating out (p<0.05), and eating habits score (p<0.01). The health-seeking group was significantly more likely to purchase ready to cook (RTC) items (59.1%) than were the other groups (p<0.001). However, the ratio of HMR purchasing for the purpose of meal replacement (p<0.05) and an HMR purchasing frequency of more than twice a week (p<0.001) were significantly lower in the health-seeking group. Reasons for selecting HMR showed a similar tendency among groups in taste (26.2%), convenience (18.7%), price (16.9%), safety (15.3%) and type of food (14.3%). However, the satisfaction scores for hygiene and safety reported by the health-seeking group were significantly lower than those reported by the other groups. More than two-thirds of all respondents were willing to purchase HMR in the future, though there were significant differences according to group: convenience-seeking group, 73.1%, health-seeking group, 70.1%, and value-seeking group, 65.7% (p<0.05). Our results suggest that the number of baby boomers purchasing HMR products will continue to grow and baby boomers will want HMR products to be more healthy (52.0%), safe (28.5%) and delicious (13.4%). An emphasis on taste was high in the convenience-seeking group, whereas an emphasis on health was high in the health-seeking and value-seeking groups. In conclusion, this study shows various food-related lifestyles amongst female baby boomers and illustrates the need to develop HMR marketing strategies targeted to these different lifestyles.

We conducted this study to examine the effects of safflower seed granular tea containing physiologically active polyphenols on antioxidative activities and bone metabolism. Forty postmenopausal women ages 49 to 64-years were recruited from Daegu and Gyeongbuk and were randomly assigned to either a safflower tea supplement (Saf-tea) group (n=27) or a placebo group (n=13). The Saf-tea group received 20 g of safflower seed granule tea per day containing a 13% ethanol extract of defatted safflower seeds, whereas the placebo group received a similar type of tea that lacked the ethanol extract. No significant changes in nutrient intake for either the placebo or Saf-tea groups were observed before or after the study period, except vitamin A intake increased after 6 months in the Saf-tea group. Dietary phytoestrogen intakes were similar in the Saf-tea group (60.3 mg) and placebo group (52.5 mg). Significant increases in plasma genistein and enterolactone were observed in the Saf-tea group. After 6 months of supplementation, serum levels of antioxidant vitamins such as a-tocopherol and ascorbic acid increased significantly, and TBARS levels decreased in the Saf-tea group compared to the placebo group. Serum osteocalcin levels were reduced (P<0.05) in the Saf-tea group after 6 months, whereas serum osteocalcin did not change in the placebo group. Urinary deoxypyridinoline/creatinine excretion was not different between the two groups at baseline, and did not change in either group after 6 months. Bone mineral density decreased significantly in the placebo group (P<0.01) but not in the supplemented group. It was concluded that polyphenols (72 mg/day), including serotonin derivatives, in the Saf-tea had both antioxidant and potential bone protecting effects in postmenopausal women without liver toxicity.
