The purpose of this study was to investigate the dietary-intake and that of health by mean of questionarie and interview for male and female old persons living in Seoul area. The contents of study included general aspects, physical status and health, nutrient intake, and food intake frequency. The results from the above survey are summarized as follows ; 1. The age group in the range of 60 to 79 years old was 71%, and the average number of family was 4.9. The educational level was 56% of elderly persons were elementary or middle school graduates . 42.8% of elderly persons had an average monthly income of \490,000 to 300,000. 2. The aged average height, weight, and physical index were 164.9cm, 55.8kg and 20.4 in male, 152.7cm, 46.0kg and 20.3 in female which were lower than the Korean average standard. (male; 167.0cm, 61.0kg, female; 156.0cm, 55.0kg) In the degree of health self-consciousness, percentage distribution of poor and very poor was 29% in male, 59% in female. Among the condition of disease, neuralgia was 23.8%, hypertension was 17.2%, diabetes was 5.4%. 3. Average daily calorie intake was $63.9{\sim}70.4%$ for male and $76.4{\sim}83.9%$ for female which were lower than the Recommended Dietary Allowances for Koreans. Protein intake was $42.9{\sim}57.3g$ (which was $72.8{\sim}82.6%$ RDA) for elderly person, the proportion of animal protein to total protein intake were $24.3{\sim}28.2%$($12.9{\sim}16.2g$). Iron, Vitamin $B_1$, $B_2$ Niacin intake exceeded the RDA, but the intake of Calcium, Vitamin C were far less than that of RDA. 4. In the correlations between nutritional intakes and environmental factors and health, economic living situations and educational level as the factors which might influence the condition of nutritional intake was significant(P<0.01). 5. Food intake frequency of meats, fishes, eggs, for average of $1{\sim}2$ days per week were $44.8{\sim}50.5%$, that of milk and milk products for scarecely week were 42.9.% Correlation of food intake frequency was divided three levels-good, fair, poor. Food intake frequency as the factors which might influence the condition of nutritional intake was significant(P<0.01). The results of the survey reveal that many of elderly show evidence of general nutrient intake deficiency, it requires first of all importance of nutrition to improve nutritional level through to promotion of elderly health.

Objectives : While cervical cancer is one of the leading cancers among women worldwide, there are a number of effective early detection tests available. However, the participation rates in cervical cancer screening among Korean women remain low. After the nationwide efforts in 1988 and thereafter to encourage participation in cervical cancer screening, few studies have investigated the effects of socioeconomic inequality on participation in cervical cancer screening. The purpose of this study was to investigate 1) the level of socioeconomic disparities in receiving cervical cancer screening by age group and 2) if there was an improvement in reducing these disparities between 1995 and 2001. Methods : Using data from the Korean National Health Status, Health Behavior and Belief Survey in 1995, the Korean National Health and Nutrition Examination Surveys from 1998 and 2001 (sample sizes of 2,297, 3,738, and 3,283), age-standardized participation rates were calculated according to education level, equivalized household income, and job status. Odds ratios and the relative inequality index (RII) were also calculated after controlling for age. Results : Women with lower education levels were less likely to attend the screening test, and the disparities by education level were most pronounced among women aged 60 years and older. The RIIs among women 60 years and older were 3.64, 4.46, and 8.64 in 1995, 1998, and 2001, respectively. Higher rates of participation were reported among those in the highest income category, which was more notable among the middle aged women (40s and 50s). An inconsistent trend in the rate of participation in cervical cancer screening by occupational level was found. Conclusions : Indicators of socioeconomic position seem to have varying impacts on the inequalities in the rates of participation in cervical cancer screening according to age group. These results demonstrate the need for more aggressive and age-based interventions and policy programs to eliminate the remaining inequalities.

Objectives: The purpose of this study was to examine the associations of current body weight and body mass index (BMI) at age three and birth weight in developing chronic respiratory illness in childhood and identify possible interaction underlying its mechanism. Methods: The study was carried out with 422 children who were enrolled in a hospital-based birth cohort. Birth related anthropometric data were collected at birth. At age 3 years, the presence of respiratory symptoms was evaluated by using the Korean version of core questionnaire for wheezing and asthma from the International Study of Asthma and Allergies in Childhood (ISAAC). Physical examination was carried out to measure the child's weight and height. Results: Children in the lowest birth weight tertile (aOR = 3.97, 95% CI = 0.94-16.68) or highest BMI tertile (aOR = 3.68, 95% CI = 1.24-10.95) at three years of age were at an increased risk of chronic respiratory illness. Children who were initially in the lowest birth weight tertile but now belong in the highest weight tertile had higher risk of chronic respiratory illness compared to those who had remained in the middle tertile (OR=16.35, 95% CI=1.66-160.57). Conclusions: Children with lower birth weight or higher BMI were at an increased risk of chronic respiratory illness. In addition, children who were initially in the lowest birth weight tertile but are now in the highest weight tertile had higher risk of chronic respiratory illness compared to those who remained in the middle tertile.

C3GHi, a novel black rice variety developed by conventional breeding has more high contents of cyanidine-3-glucoside (C3G) and a more strong antioxidant than normal black rice. In this study, we investigate the antioxidative potential and anti-diabetic activity of C3GHi and extract of it for the purpose of development of functional materials or replacement meal for diabetic patients. Using in vitro antioxidative activity assay system such as DPPH radical quenching assay, superoxide anion radical scavenging assay, inhibition of lipid peroxidation and DNA breakage assay, C3GHi extract was observed to have more high antioxidative activity than normal black rice breed. The glycemic index of a freeze dried powder of C3GHi brown rice showed $43.7\pm18.8$, which belonged to low GI food (GI of 55 or less). Using in vivo diabetic model such as db/db mice model and streptozotocininduced diabetic model, C3GHi rice extract decrease blood glucose level and inhibit oxidative stress in blood. From the results, we think that the C3GHi varieties have a potential for the functional materials or ingredient of meal replacement for diabetic patients.

In order to determine the effects of strawberry powder on the baking quality of cakes, yellow layer cakes were prepared with four freeze-dried strawberry powders substitutes, at levels of 0%, 1%, 2%, 3%, 4% and 5%. Then, the physical properties, baking properties and sensory characteristics of the finished cakes were assessed. The cakes were stored for 6 days at $22^{\circ}C$ and the change in hardness during storage was evaluated. The Viscosity of the doughs, as well as the specific gravity, increased as the amount of strawberry powder in the flour increased. The volume indices of the strawberry powder cakes were less than that of control, but the other indices did not differ from those of the controls. The crust color of the strawberry cakes evidenced a reduction in L. a and b values. The crumb color also evidenced a reduction in the L and b values, but the a values increased. Sensory characteristics were evaluated by 60 students from the Dept. of Food and Biotechnology. Crust color, crumb color, moistness, softness, taste and overall acceptance were measured via a 5-scale acceptance test. The crust color of cakes containing more than 3% strawberry powders and the crumb color of all strawberry cakes evidenced lower scores than the controls. Cakes containing 5% strawberry powders were least acceptable in terms of overall characteristics. Although cakes prepared with flour containing up to 4% strawberry powder were less acceptable than the controls, general sensory scores ranged in an average${\sim}$like range. The incorporation of strawberry power into cakes was shown to increase the overall hardness.

The improved thermal stability and anti-oxidation properties of lyocell fiber were studied based on flame retardant treatment by using $Na_3PO_4$ solution. The optimized conditions of flame retardant treatment were studied on various concentrations of $Na_3PO_4$ and the mechanism was proposed through experimental results of thermal stability and anti-oxidation. The integral procedural decomposition temperature (IPDT), limiting oxygen index (LOI) and activation energy ($E_a$) increased 30, 160% respectively via flame retardant treatment. It is noted that thermal stability and anti-oxidation improved based on char and carbon layer formation by dehydrogenation and dissociation of C-C bond resulting the hindrance of oxygen and heat energy into polymer resin. The optimized conditions for efficient flame retardant property of lyocell fiber were provided using $Na_3PO_4$ solution and the mechanism was also studied based on experimental results such as initial decomposition temperature (IDT), IPDT, LOI and $E_a$.

Background: We hypothesized that if a fluoroscopic image of the lumbar sympathetic ganglion block (LSGB) showed the spread patterns of contrast at both the L2/3 and L4/5 disc areas, then this would demonstrate a more profound blockade effect because the spread patterns are close to sympathetic ganglia. In addition, we compared the effects of LSGB and transforaminal epidural steroid injection (TFESI) for the patients suffering with spinal stenosis. Methods: Eighty patients were divided into two groups (Group S: the patients treated with TFESI, Group L: the patients treated with LSGB). The patients of group L were classified into three groups (groups A, B and, C) according to their contrast spread pattern. The preblock and postblock temperature difference between the ipsilateral and contralateral great toe ($DT^{pre}$, $DT^{post}$, $^{\circ}C$), and the DTnet were calculated as follows. $DT^{net}$ = $DT^{post}$ - $DT^{pre}$. Results: Both group showed a significant reduction of the visual analogue score (VAS) and the Oswestry disability index (ODI) score. Only the patients of group L showed a significant increase of their walking distance (WD). Group A showed the most significant changes in the $DT^{post}$ ($6.1{\pm}1.2^{\circ}C$, P = 0.021), and the DTnet ($6.0{\pm}1.0^{\circ}C$, p = 0.023), as compared to group C. Conclusions: LSGB showed a similar effect on the VAS, and ODI, and a significant effect, on WD, compared with TFESI. Group A showed a significant sympatholytic effect, as compared to group C.

Purpose: This study aimed to determine the effects of a 12-week metabolic syndrome BeHaS (Be Happy and Strong) program in elderly people with metabolic syndrome living alone, based on a community-based participatory research (CBPR). Methods: A nonequivalent control group pre-posttest design was used, and the participants were 43 elderly people living alone (experimental group 24, control group 19). The experimental group received a one-hour program per week and two individual health consultations during 12 weeks. The control group received two sessions about the metabolic syndrome and two individual health consultations. The effects of health behavior, blood pressure, blood sugar levels, abdominal circumference, triglycerides, and self-esteem were evaluated. The data were analyzed using the independent t-test and Mann-Whitney U test. Results: The health behavior with respect to the metabolic syndrome in the experimental group increased significantly (t = - 3.19, p = .002). Both diastolic blood pressure and abdominal circumference decreased in the experimental group (t = 2.00, p = .028 and t = 3.91, p < .001). No significant differences were observed between the groups in systolic blood pressure, fasting blood sugar levels, triglycerides, and self-esteem. Conclusion: The 12-week metabolic syndrome BeHaS program using community resources improves the health of elderly people with metabolic syndrome living alone. Based on these findings, further studies on the effectiveness of the metabolic syndrome BeHaS program and the experiences of those who participated in the CBPR are warranted.

To evaluate the skin aging inhibition effect of fermented Reynoutria elliptica, skin aging model was produced by the irradiation of UVB to hairless mice for 5 weeks. The skin erythema index for the positive control (PC), not fermented Reynoutria elliptica extract (NFR), and fermented Reynoutria elliptica extract (FR-500, 1000, 2000) groups were lower than that of the control group. However, both lipid and water capacity for the PC and FR groups were higher than those of the control group. Collagen fibers in dermis of the FR groups were almost intact with a regular arrangement which were similar to the normal (NO) group. Also, relatively much less number of mast cells and inflammatory cells were found in FR groups. The skin TBARS contents and XO activity in the FR group were significantly lower than the control group. The activities of GSH, SOD and CAT for the FR groups were significant higher than the control group. Therefore, fermented Reynoutria elliptica extract can be practically useful for the prevention or improvement of skin aging in terms of health promotion and beauty for the people.
