BACKGROUND/OBJECTIVES: Calcium is important but deficient in diets of young adult women. This study aimed to examine if cognitive factors and eating behaviors differ according to calcium intake based on the Social Cognitive Theory. SUBJECTS/METHODS: Subjects were female college students in Seoul, Korea. Three hundred students completed the questionnaire regarding calcium intake, nutrition knowledge, outcome expectations, self-efficacy and eating behaviors. Data on 240 students were analyzed using t-test or ${\chi}^2$-test. Subjects were categorized into two groups, high calcium intake (HC, ${\geq}650mg/day$) and low calcium intake (LC, < 650 mg/day), according to recommended intakes of calcium for women aged 19-29 years. RESULTS: The LC group constituted 77.9% of total subjects. Nutrition knowledge was not different according to calcium intake. Three out of 12 outcome expectations items were significantly different between the HC and LC groups. Subjects in the HC group agreed more strongly with the practical benefits of consuming calcium-rich foods, including 'taste' (P < 0.01) and 'going well with other snacks' (P < 0.05), compared to those in the LC group. Negative expectations of 'indigestion' were stronger in the LC group than HC group (P < 0.001). Among self-efficacy items, perceived ability of 'eating dairy foods for snacks' (P < 0.001), 'eating dairy foods every day' (P < 0.01), and 'eating calcium-rich side dishes at meals' (P < 0.05) differed significantly between the HC and LC groups. Eating behaviors including more frequent consumption of dairy foods, fruits or fruit juice (P < 0.001), anchovy, seaweeds, green vegetables, protein-rich foods (P < 0.05), and less frequent consumption of sweets or soft drinks (P < 0.01) were significantly related to calcium intake. CONCLUSIONS: This study found that outcome expectations, self-efficacy in consuming calcium-rich foods, and eating behaviors are important in explaining calcium intake. Nutrition education needs to address practical benefits, reduce negative expectations of calcium-rich foods, increase self-efficacy, and modify eating behaviors contributing to calcium intake.

Purpose: This study determined the level of stress and type of coping style of spouses with high-risk pregnant women. Methods: Subjects were 102 spouses with high-risk pregnant women at 6 hospitals in Seoul and Gyeonggi province from January to August, 2009. The tools for this study were stress scale and coping scale. The data were analyzed by t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. Results: The average score of subjects stress was 2.18 and coping score was 2.46 point out of 4.00. The highest score of stress categories was 2.44 point in emotional problems and the lowest score was 1.72 in communication and support resources. The stress level was significant differences according to length of marriage, number of hospital visits, satisfaction with marriage relationship, hospitalization days and gestational age respectively. Spouses tended to use an active coping style (2.60) rather than a passive coping style (2.31). There were significant differences according to mother's age and gestational age in active coping and educational level in passive coping. Conclusion: Considering the level of stress coping style and characteristics of high-risk pregnant women's spouses, a nursing intervention should be provided to help them alleviate stress and to encourage active coping.

Roots of Astragalus membranaceus (A. membranaceus) (Astragali Radix, AR) has been used as a herbal medicine for gastrointestinal disorders in China, Korea, Japan, and other Asia countries. In this study we investigated the effects of the AR 70% ethanol extract and compounds isolated from AR on gastritis in rats and growth of human gastric cancer cells. AR 70% ethanol extract showed the potent acid-neutralizing capacities and partly cytotoxicity of Helicobacter pylori and human AGS gastric cancers cell. Astragaloside I and daucosterol, which were isolated from AR, significantly inhibited HCl/ethanol-induced gastric lesions. In addition, daucosterol increased the mucus content to almost the same as the positive control. The results of this study suggest that astragaloside I and daucosterol may be good candidates for the development of new drugs or neutraceuticals which can be used for the treatment or prevention of gastritis.

The objective of this study was to assess the metabolic profiles and diet quality in college women by their mother's diabetes mellitus status. The study subjects, all college women, were classified into two groups based on the their mother's diabetes mellitus status: the offspring group (OG) and the control group (CG). The OG exhibited significantly higher body mass indices (p < 0.01), percentages of ideal body weight (p < 0.05) and high density lipoprotein cholesterol (p < 0.05) values than the CG. Additionally, the OG showed significantly higher daily average intakes of total energy (p < 0.05). fat (p < 0.001), riboflavin (p < 0.01) and calcium (0.01) than the CG. The indices of nutritional quality of protein (p < 0.05) and Na (p < 0.05) in the CG were significantly higher than those of the OG. However. we noted no significant differences in the mean adequacy ratio between the CG and OG. Overall, our results demonstrated that this factor appears to potentially be related to the subjects' mother's diabetes status. However, CG and OG were significantly different within normal range. Furthermore, nutrient adequacy indices in the CG were not assessed well in regard to energy, riboflavin, vitamin C, and calcium. Therefore, it appears that ideal body weight and diet quality should be controlled in order to prevent diabetes and diet-related problems, both in the CG and the OG.

The rhizoma of Zingiber officinale has been used as antiemetic, expectorants, stomachache relieving drugs and digestive accelerators. From the observation of antigastritic action of the methanol extract of the rhizoma, it was fractionated with hexane, chloroform, ethyl acetate and butanol, followed by bioassay on antigastritic and antiulcerative activity. The hexane and the chloroform fraction reduced significantly HCl ethanol induced gastric lesion at the dose of 370 and 210 mg/kg, p.o., respectively. On the gastric ulceration and gastric secretion in pylorus-ligated rats, the hexane fraction decreased the volume of gastric secretion and acid output, and also increased pH at the dose of 370 mg/kg, i.d.. It showed considerable curative ratio of acetic acid induced ulcer without inhibition of indomethacin induced gastric lesion. The methanol extract showed low acute toxicity with minimum lethal dose of more than 3000 mg/kg, p.o. in mice. In conclusion, Zingiberis rhizoma exhibited antigastric and antiulcerative activity which might be attributable to inhibition of gastric secretion. It is revealed that the active component may be present in the hexane fraction.

The aim of this study was to investigate the UV-resistance of radiation-resistant bacteria isolated from the water of Han River, South Korea. The water sample was irradiated with 3 kGy gamma radiation prior to isolation. Radiation-resistant bacterial strains were isolated by standard serial dilution method on R2A and 1/10 diluted R2A agar. The resulting purely isolated 60 cultures of bacteria were analysed for UV resistance and used in further studies. Based on the comparative analyses of 16S rRNA gene sequences, the bacterial isolates were divided into 3 phyla (4 genera): the phylum Deinococcus-Thermus (the genus Deinococcus) was 61.7%, Bacteroidetes (Hymenobacter and Spirosoma) was 23.4%, and Firmicutes (Exiguobacterium) was 15%. The results suggested that twenty-nine isolates are candidates new species belonging to Deinococcus, Hymenobacter, and Spirosoma, or other new genera. Nine bacterial strains were selected among the novel candidates and the UV-resistance analysis was conducted. All the candidate bacterial strains showed high UV resistance, similar to that of D. radiodurans R1.
