The purpose of this study was to examine consumers' behaviors toward ready-to-eat foods and to develop ready-to-eat food market segmentation in Korea. The food-related lifestyle and purchase behaviors of ready-to-eat foods were evaluated using 410 ready-to-eat food consumers in the Republic of Korea. Four factors were extracted by exploratory factor analysis (health-orientation, taste-orientation, convenience-orientation, and tradition-orientation) to explain the ready-to eat food consumers' food-related lifestyles. The results of cluster analysis indicated that "tradition seekers" and "convenience seekers" should be regarded as the target segments. Chi-square tests and t-tests of the subdivided groups showed there were significant differences across marital status, education level, family type, eating-out expenditure, place of purchase, and reason for purchase. In conclusion, the tradition seekers consumed more ready-to-eat foods from discount marts or specialty stores and ate them between meals more often than the convenience seekers. In contrast, the convenience seekers purchased more ready-to-eat foods at convenience stores and ate them as meals more often than the tradition seekers. These findings suggest that ready-to-eat food market segmentation based on food-related lifestyles can be applied to develop proper marketing strategies.

The purpose of this study was to compare the sensory effects of different culinary methods such as electric pan cooking and charcoal roasting on gamma irradiated ready-to-eat chicken at 10 kGy. Evlauation of sensory properties were measured by estimating the organoleptic characteristics and physicochemical properties (TBARS, hardness and color different matters). The results showed that gamma irradiation after charcoal-roasting could more effectively moderate the decrease of sensory qualities and reduce off-flavor of ready-to-eat chicken than gamma irradiation after following electric pan cooking. These results suggest that gamma irradiation after charcoal broiling can be an effective culinary method for the preparation of ready-to-eat chicken.

This study was executed in order to analyze the purchasing practices, preferences, and satisfaction of consumers purchasing ready-to-eat foods. The study was executed from the $20\;May{\sim}30\;June$ 2007 in the Daegu and Gyeongsangbuk-do area. Questionnaires were distributed among 480 people. Of these, 410 questionnaires were collected and applied to a statistical analysis. Statistical analyses were conducted using the SPSS package program (version 14.0 for windows). The results of the statistical analyses were as follows. 42.4% males and 57.6% females participated in this study. The biggest motivation behind the purchase of ready-to-eat foods was convenience, 51.0%. The most common venues where these foods were purchased were supermarkets or discount marts, 67.6%. The ratio of substituting ready-to-eat foods for meals was 70.5%. The consumption practices of ready-to-eat foods of the consumers according to purchase place illustrated significant differences in the average expense per person each time (p<0.01), co-consumer (p<0.001), and age (p<0.05). The purchase preference was high with kimbaps (73.4%), hamburgers (29.8%), sushis (29.0%), and sandwiches (27.9%). Unmarried individuals showed a significantly higher overall liking and satisfaction for ready-to-eat foods than married individuals (p<0.001). Individuals living without a family was significantly higher overall liking and satisfaction than individuals living with a family (p<0.05). Individuals who spent an average of 10,000 won per time showed a significantly higher overall liking and satisfaction than those who spent below 10,000 won per time (p<0.05). In the presence of a friend as a co-consumer of ready-to-eat foods, satisfaction was significantly high (p<0.01). Consumers who purchased ready-to-eat foods at meal times, showed a significantly higher overall liking, compared to those who purchased such food products in between meal times (p<0.01). The preference and satisfaction degree of the consumer must be reflected by product development, quality improvement and marketing plan establishment.

This study was designed to investigate the mechanism of the synergistic anticancer effect of Astragalus membranaceus (AM) and Adenophora triphylla var. japonica (AT) in H1299 human lung carcinoma cells. A combined treatment of ethanol extract of AM (EAM) and AT (EAT) explosively increased the reactive oxygen species (ROS) generation in H1299 cells compared to the single treatment of each of them. Co-treatment of N-acetyl-L-cysteine (NAC) with EAM and EAT markedly enhanced the cell viability and suppressed apoptosis in H1299 cells, suggesting that ROS generation contributed to the anticancer effect of EAM and EAT. Interestingly, the combined treatment of EAM and EAT down-regulated p-AKT in H1299 cells, which was abrogated by NAC treatment. These results clearly indicated that ROS generation mediated the inactivation of AKT. Co-treatment of LY294002 with EAM and EAT significantly reduced the cell viability at a concentration which EAM and EAT didn't show any cytotoxicity. In addition, the recovery of cell viability by co-treatment of NAC with EAM and EAT was quite reversed by LY294002 treatment, which confirmed that the inactivation of AKT played a pivotal role in ROS-mediated apoptosis. Taken together, our results demonstrated that the synergistic anticancer effect of EAM and EAT was mediated by ROS generation and inactivation of AKT. We provide a valuable preclinical data for the development of more effective combination of AM and AT to treat lung cancer.

This study was performed to analyze the microbiological hazards of ready-to eat sandwiches and to evaluate the effect of implementing a hazard analysis and critical control points (HACCP) for quality improvement of ready-to-eat sandwiches. In total, 174 samples were examined for the microbiological hazard analysis. About 37.4% of the samples had an aerobic plate count ${\geq}$6 log CFU/g, and the numbers of coliforms exceeded 3 log CFU/g in 82.2% of the samples. Additionally, Staphylococcus aureus, E. coli, and Salmonella spp. were detected in 10.3%, 4.6%, 1.1% of sandwiches, respectively. In contrast, E. coli O157:H7, and Listeria monocytogenes were not detected in any of the samples. The results of the microbiological verification after implementing a HACCP throughout the production process indicated that S. aureus, E. coli, Salmonella spp., E. coli O157:H7, and L. monocytogenes were not detected in any of the samples. Consequently, implementing a HACCP is effective for quality improvement of ready-to-eat sandwiches.

Purpose: This study aimed to identify factors-both infant-related and maternal-associated with pressure to eat as a feeding practice among mothers with infants. Methods: This study used a cross-sectional design and included 163 mothers of infants aged 2~12 months. Of the 180 self-reported questionnaires that were distributed, 163 (91%) were included in the data analysis. Multiple regression analysis was used to identify the factors associated with pressure to eat as a feeding practice among the mothers. Results: Infant's temperament (β=-.17, p=.035), mother's body mass index (β=-.16, p=.048), and concern about the infant being underweight (β=.30, p=.001) were associated with pressure to eat as a feeding practice among mothers. The explanatory power of these variables in the predictive model was 19.2%. Conclusion: Educational programs should be developed for improving mother's awareness of cues from infants with difficult temperament. In addition, educational interventions regarding the correct evaluation of infant's weight are needed to relieve mother's concern about their infant's being underweight. These interventions might be helpful to reduce the prevalence of pressure to eat as a feeding practice among mothers with infants.

Metabolic syndrome, including obesity, glucose intolerance and elevated blood pressure, is related to type 2 diabetes and cardiovascular disease. Previous studies have reported the anti-oxidative, anti-inflammatory and anti-diabetic effects of purple corn extract. We investigated the efficacy of purple corn extract (PC) against high-fat diet (HFD)-induced obesity and glucose intolerance, and examined the underlying mechanisms by analyzing expression of proteins and genes involved in glucose regulation and macrophage infiltration. C57BL/6 mice were fed with normal chow diet (ND), or HFD treated with distilled water (DW, control) or PC, for 10 weeks. Although body weights were similar in the HFD-fed groups, we observed a decrease in the liver and epididymal adipose tissue (EAT) weights, and enhanced glucose tolerance test (GTT) results in the PC group, as compared with DW group. Liver showed increased Akt phosphorylation in the PC-treated mice; however, no changes were observed in the EAT, for all groups. In PC-treated mice, decreased macrophage infiltration was seen in the EAT, with a reduced expression of macrophage marker genes. Finally, proinflammatory cytokine gene expressions were decreased by PC in the EAT, and a modest trend for downregulation was observed in the liver. Hence, we conclude that PC may decrease glucose intolerance by increasing the phosphorylation of Akt and reducing the macrophage infiltration into the EAT.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

The anti-cancer effects of Astragalus membranaceus (AM) and Adenophora triphylla var. japonica (AT) have been described. Each of their effects mainly focused on the immunopotentiating and apoptosis inducing-ability in several cancer cell lines. Although the combination of AM and AT is occasionally used in Chinese medicine to treat lung cancers, their synergistic effect has not been proved yet. This study was designed to verify whether AM combined with AT exhibits a synergistic anti-cancer effect in H1299 human lung carcinoma cells. The ethanol extracts of AM (EAM) and AT (EAT) showed only slight cytotoxicity in H1299 cells when treated alone. However, the combination of EAM and EAT markedly suppressed the cell growth measured by MTT assay and trypan blue counting assay. In addition, co-treatment of EAM with EAT significantly reduced the colony-forming ability compared with single treatment of EAM or EAT in H1299 cells. We demonstrated that the synergistic effect of AM and AT was related with apoptosis induction proved by an accumulation of chromatin condensation, annexin V-positive cells, sub-G1 phase population, and cleaved-PARP expression, which were not observed by single treatment of EAM or EAT. In conclusion, the combination of EAM and EAT exhibited superior anti-cancer activity in H1299 cells than single treatment of EAM or EAT. We suggest that EAM combined with EAT might be a novel therapeutic option for lung cancer patients, and provide a reference for the development of more effective combination of Chinese herbs to treat lung cancer.
