Objectives : This study aims to investigate the correlation between the characteristics of personality on MMPI scale, and the siblings relation, number of current family living with, gender and age of the Oriental Medical University students. Methods : For this study, we carried out the MMPI profiling and gathered information regarding the sibling relation of the subjects. We studied the correlation between the two measures, and the correlation between MMPI scales and the subjects' gender and age. Results : 1. The group without siblings had higher STY figures then the groups with siblings. 2. There was no significant differences in MMPI profiles among the only child group, first-born group, second-born group, and third-born group. 3. The married group showed higher Pd, Pt, Sc, BDL figures than the unmarried group. 4. As the number of family members currently living with increased, the BDL and STY figures decreased. 5. The male group had higher Hs, Hy, Pa, Ma, NAR, BDL, ANT, CPS, PAR, and SZD figures, while the female group had higher D, Pd, Mf, Pt, HST, PAG, and DEP figures. 6. As the subjects' age increased, the figure of Hs, D, Pt, Sc, Si, AVD, and SZD increased, while the HST figure decreased. Conclusions : By the above results, we can assume that the sibling relations and the order one is born in the family does not affect one's personality much in grown-ups; whereas the gender and age affect the personality.

The principal objective of this study was to assess the nutritional status and dietary quality in low-income elderly individuals residing at home (LH) or in health care facilities (LHCF) with dietitian. This study was conducted via anthropometric measurements, questionnaire interviews, and dietary surveys using a 24 hr recall method with 120 low-income elderly individuals (LHCF=46, LH=74). The average ages of the LH and LHCF group were 76.3 years and 78.6 years, respectively. The LH group evidenced a significantly higher frequency of skipping meals than the LHCF group. The average energy intakes of the LHCF and LH group were 1921.0 kcal and 1443.9 kcal, with a significant difference (p<0.001). Most of the nutrient intake and intake rates for recommended intake were significantly higher among the LHCF group as compared with the LH group. The LHCF group showed significantly higher values for the nutrient adequacy ratio (NAR), the mean adequacy ratio (MAR), nutrient density (ND), and the index of nutritional quality (INQ) by dietary qualitative estimation than in the LH group. The Korean diet diversity scores (KDDS) were 3.66 for LH group and 4.93 for the LHCF group, thus were significantly higher in the LHCF group than in the LH group. The results of the present study demonstrate that the LH group appeared to experience more dietary problems than the LHCF group. It was suggested that nutritional education is needed for low-income elderly individuals living at home, in order for them to learn proper dietary management. This can be achieved via educational programs in social welfare institutions, incentives toward employment as a dietitian, and implementation of community-based support.

This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.

Two near-isogenic lines with dark and pale green leaves, derived from the F$\_$7/ generation of wxl26 cross were compared on photosynthetic capacity, growth parameters, grain yield and yield-related characters. Dark green-leaved lines contained much greater content of chlorophyll a and b than pale green-leaved ones, but chlorophyll a to b ratio showed no difference between them. The photosynthetic nte per unit leaf area was higher in dark green-leaved lines than in pale green-leaved ones in the flag leaves at heading stage, but that per unit chlorophyll content showed reversed result. The crop growth rate from transplanting to heading was consistantly higher in the dark green-leaved lines, resulting from their greater net assimilation rate. Dark green-leaved lines produced greater number of panicles and spikelets per hill, out yielding pale green-leaved lines, but ripened grain ratio and 1000-grain weight showed no differences between those lines.

Background: Flavonoids are natural polyphenols found widely in citrus fruit and peel that possess anti-adipogenic effects. On the other hand, the detailed mechanisms for the antiadipogenic effects of flavonoids are unclear. Objectives: The present study observed the anti-adipogenic effects of five major citrus flavonoids, including hesperidin (HES), narirutin (NAR), nobiletin (NOB), sinensetin (SIN), and tangeretin (TAN), on AMP-activated protein kinase (AMPK) activation in palmitate (PA)-treated HepG2 cells. Methods: The intracellular lipid accumulation and triglyceride (TG) contents were quantified by Oil-red O staining and TG assay, respectively. The glucose uptake was assessed using 2-[N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-d-glucose (2-NBDG) assay. The levels of AMPK, acetyl-CoA carboxylase (ACC), and glycogen synthase kinase 3 beta (GSK3β) phosphorylation, and levels of sterol regulatory element-binding protein 2 (SREBP-2) and 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) expression were analyzed by Western blot analysis. The potential interaction between the flavonoids and the γ-subunit of AMPK was investigated by molecular docking analysis. Results: The flavonoid treatment reduced both intracellular lipid accumulation and TG content in PA-treated HepG2 cells significantly. In addition, the flavonoids showed increased 2-NBDG uptake in an insulin-independent manner in PA-treated HepG2 cells. The flavonoids increased the AMPK, ACC, and GSK3β phosphorylation levels and decreased the SREBP-2 and HMGCR expression levels in PA-treated HepG2 cells. Molecular docking analysis showed that the flavonoids bind to the CBS domains in the regulatory γ-subunit of AMPK with high binding affinities and could serve as potential AMPK activators. Conclusion: The overall results suggest that the anti-adipogenic effect of flavonoids on PA-treated HepG2 cells results from the activation of AMPK by flavonoids.

To study the comparison of aboveground biomass of paulownia coreana Uyeki of 6-year-old, located in Seongju of non-attacked forest and Ulsan of damaged forest by the air pollution were selected. Ten sample trees in Seongju district and seven trees in Ulsan selected taking account of DBH were measured for 16 trees in total within a $10{\times}10m$ experimental plot. The diagram of oven-dry weight distribution of stem, branch and needle for each 1m segment was constructed. The logarithmic regression equations between dry weight of each component and the two-variables, DBH and tree height, combined term were presented. IF the estimations are extended to a hectare area stand, it contains 47.49 tons of aboveground biomass in Seongju district and 19.05 tons of it in Ulsan. The annual net productions were 11.64 tons of above 2.29 kg/kg/yr in Ulsan and the efficiency of leaf to produce stem was 2.99kg/kg/yr in Seongju and 0.83kg/kg/yr in Ulsan.

We analyzed data from the combined 2008~2009 Korean National Health and Nutrition Examination Survey (KNHANES) to compare the health factors related to menopausal stages in 45~60 year old Korean women. In this study, we classified the subjects into a premenopausal group (n = 439) and a postmenopausal group (n = 683). In the postmenopausal group, age was higher (p < 0.001), monthly income (p < 0.01) and education levels (p < 0.001) were significantly lower than in the premenopausal group. Body fat % and waist circumferences were also higher in the postmenopausal group than in the premenopausal group. The serum glucose (p < 0.05), total cholesterol (p < 0.001), LDL-cholesterol (p < 0.001), triglyceride (p < 0.001), GOT (p < 0.001), GPT (p < 0.001) in the postmenopausal group were higher than in the premenopausal group. The postmenopausal group showed a significantly lower quality of life compared to the premenopausal group (p < 0.01). With regard to dietary quality, nutrient adequacy ratio (NAR) of vitamin A, vitamin $B_1$, vitamin $B_2$ and niacin in the postmenopausal group were significantly lower than in the premenopausal group. The levels of glucose, total cholesterol, LDL-cholesterol, and triglyceride showed a significantly positive correlation with age, waist circumferences, body fat % and BMI. The 45~60 year old Korean women in this study showed high levels of obesity and serum lipids. Also, intakes of the vitamins and minerals of the women did not meet the level of Dietary reference intakes for Koreans. Therefore, nutritional risk may be high in the women, especially in postmenopausal women. In order to prevent the health risk, women's health care including the quality of the meal should be considered.

It is known that Korean pregnant women take iron supplements at a higher than the recommended level. This study was designed to provide data on current iron intake levels both from food sources and supplement to better guide iron supplement use during pregnancy. We also explored associations of iron supplement intake levels with various sociocultural factors and pregnancy outcomes. Dietary intakes of 510 pregnant women were assessed by a validated 102-item food frequency questionnaire, and information on types and amounts of nutritional supplement intakes were also attained. While dietary intake levels of most nutrients exceeded the KDRIs (Korea Dietary Reference Intakes: EAR: Estimated Average Requirements), folate fell short of the KDRIs. A total of 428 women (83.9%) reported to take iron supplement. The pregnant women were divided into the three groups (group I: Fe supplement intake ${\le}$ EAR, group II: EAR < Fe supplement intake ${\le}$ 3 times of EAR, group III: 3 times of EAR < Fe supplement intake). The mean dietary intake of iron was 24% of the total iron intake for pregnant women. Iron intake from food was not significantly different among I, II, and III. In case of iron intake from supplements, the most frequent dose (34.1%) was 90-100 mg/day, and the mean iron supplement intake was 362% of the EAR. The study findings showed that those with higher levels of iron supplements had better meal quality measured by NAR (Nutrient Adequacy Ratio) and INQ (Index of Nutrient Quality). In addition iron supplement intake levels were significantly related to age (20s: 66.5 ${\pm}$ 38.6 mg/day, 30s: 77.3 ${\pm}$ 47.8 mg/day, p < 0.0116) and experience of childbirth (1st pregnancy: 70.9 ${\pm}$ 41.2 mg/day, 2nd pregnancy: 64.5 ${\pm}$ 39.5 mg/day, ${\ge}$ 3rd pregnancy: 94.4 ${\pm}$ 63.8 mg/day, p < 0.005). However, no significant difference was found between iron supplement intake levels and various pregnancy outcomes including birth weight, birth height, gestational age, weight gain during pregnancy, and jaundice. It is worrisome that iron intake by supplement use greatly exceeded the EAR, suggesting the need of appropriate guidelines for iron supplement intake during pregnancy. Thus iron overdose from supplements in pregnancy should be considered as a serious condition.

We investigated the gene expression patterns and the mechanisms of action of the apoptotic response by microarray analysis of human keratinocyte HaCaT cells treated with ginsenoside Rb1, a saponin of Panax ginseng C. A. Meyer. Genes related to apoptosis, the G2/M transition of the mitotic cell cycle, cell division, mitotic nuclear division, and intracellular protein transport were 2-fold up-regulated in HaCaT cells treated with the ginsenoside Rb1, whereas genes related to DNA repair, regeneration fission, and extracellular matrix organization were 2-fold down-regulated. Apoptosis signaling may be mediated by FAS and PLA2G4A, and pathway analysis indicated that STAT3 might be an upstream regulator of these genes. The activity of FAS and PLA2G4A was verified by qPCR, which showed that FAS was increased about 2-fold in HaCaT cells treated with $10{\mu}g/ml$ of ginsenoside Rb1 for 24 hr, PLA2G4A was increased about twice after 6 hours, and gene expression was increased more than 2-fold after 24 hr. Knockdown of STAT3 with siRNA decreased FAS expression and increased PLA2G4A expression but only FAS was passed from the upstream regulator STAT3. These results indicate that STAT3, which is an upstream regulator, induces apoptosis via FAS during treatment with ginsenoside Rb1.

Marine deposite soil was studied to evaluate morohological changes of paddy rice under subdrainage control. The content of organic and inorganic mate rial were low at high temperature in the mid-summer. This soil lacked air and accumulated more H$_2$ S. Thus rice root was rotted with high infection of virus and insect and yield was relatively low.
