Methoxy polyethylene glycol-epoetin beta (MPG-EPO), a continuous erythropoietin receptor activator, is a new erythropoiesis-stimulating agent with a long half-life. The purpose of this prospective study is to assess the effects of once-monthly subcutaneous MPG-EPO on hematological responses and nutritional status in peritoneal dialysis patients. Forty four patients undergoing stable peritoneal dialysis were enrolled into the study. Darbepoetin alfa therapy, in peritoneal dialysis patients, was converted to the monthly administration of subcutaneous MPG-EPO for 6 months. The starting dose of MPG-EPO was based on the previous weekly dose of darbepoetin alfa. The dose adjustments were performed to maintain the hemoglobin (Hb) levels in a target range of 10.5-11.0 g/dL. If the Hb levels exceeded 11.0 g/dL, MPG-EPO was temporarily interrupted for 1 month. The mean Hb levels were stable with the values of $9.5{\pm}1.1$ g/dL at baseline, and $10.4{\pm}0.9$ g/dL at the 6th month after conversion. The mean differences in the changes of Hb levels between the baseline and the 6th month were $0.9{\pm}1.4$ g/dL, which was statistically significant. However, the mean differences of iron, transferrin saturation and ferritin concentrations were not significant. It did not show significant differences in the changes of the nutritional parameters. These results suggest that the once-monthly subcutaneous administration of MPG-EPO for 6 months effectively maintains the Hb levels and nutritional status in peritoneal dialysis patients. Taken together, the once-monthly subcutaneous administration of MPG-EPO was practical and might improve the clinical compliance for the management of renal anemia in peritoneal dialysis patients.

For the purpose of developing 'Web-Based Nutritional Education Program', this study analyzed nutritional problems of junior/senior high school students and set appropriate instructional goals for nutritional education program. Survey questionnaires were distributed from October 21,2002 to October 26, 2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9％ of the total questionnaires distributed. According to the survey results, three student groups (male and female students at junior high schools and female students at senior high schools) had lower than an ideal body weight. In case of their Basal Metabolic Indices (BMI), the female students and junior high school students showed a tendency to be underweight, while the other three student groups were within the normal range. The result of the survey showed that all four groups of students showed a deficiency in nutrient intake of calories, calcium and thiamin when compared with Korean RDA. Particularly, in the case of the female students at senior high schools, the deficiency of iron intake was a problem. The survey about food attitudes and food habits of the students showed that the senior high school students had more problems when compared with their junior high school counterparts (p < .001). Therefore, the instructional goals of nutritional education program were set as follows: 1) To improve the level of understanding and the perception of junior and senior high school students about the importance of a dietary lifestyle. 2) To change food attitudes and nutritional knowledge related to individual dietary 1ifestyle, so as to maintain good health through the enhancement of the students' physical activities. We found out that it is critically important to factor in the existing problems of food attitudes and food habits, as well as nutrient intake among junior and senor high school students when setting objectives for nutritional education programs.

The purpose of this study is to examine the nutrition knowledge, characteristics related to, nutrient intakes, anthropometrics, biochemical indices of university female students by major (food and nutrition versus physical science). Data were taken from 120 university female students (60 from each major) and the results follows. The mean age of the subjects was 19.6 years old. Most of subjects responded that they were healthy; subjects majoring in physical science scored higher in regular exercise (p < 0.01) and were more satisfied with their own body figures (p < 0.01), compared with the counterparts. The total nutrition knowledge score was $81.01{\pm}12.3$ for food and nutrition majors and $72.5{\pm}15.2$ points for physical science majors. (p < 0.01) The percentages of body fat were significantly higher in the food and nutrition students than the counterparts. (p < 0.001) The result of biochemical analysis showed that both groups were in normal range. But there was some statistically significant difference between groups in GTP, HDL-cholesterol and ALP levels. It suggests that regular exercise might have a positive effect on the body. This study showed that although both groups had different knowledge of nutrition, there was not much difference in the intakes of nutrients. But especially, the intakes of calcium and iron were quite low in both groups. Subjects majoring in Physical science had more lipid intake, but they had lower body fat. This suggests that regular exercise in this group might have effects on the percentages of body fat. In future study, nutrition education might be planned to increase nutrition knowledge and to connect nutrition knowledge to eating behaviors and to promote health to regular exercise. Also, the desire and the social perception for pursuing alean body figure and being underweight should be changed for optimal health.

The purpose of this study was to evaluate the nutrient intake, diversity and prevalence of diseases according to noodle consumption using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2010. Korean adults (>20) were classified into two groups, noodle group (NG) and non-noodle group (NNG). NG was found to have higher intakes of protein, calcium, iron, sodium, potassium, and niacin. The DVS and DDS according to noodle consumption were found to be 21.76 and 3.51 for NG, and 18.56 and 3.40 for NNG, this result was thought to show that the diet of NG was more satisfactory than that of NNG in terms of dietary diversity. In the bone mass of entire subjects, NG showed higher figures in the femoral neck and lumbar spine than NNG. For bone mineral density, NG exhibited higher figures in the femoral neck, and for T-scores, the values of NG was significantly higher in the femoral neck than those of NNG. However, the prevalence of osteoporosis of NG and NNG was 11.6% and 9.5%. The prevalence of osteopenia of NG and NNG was 43.0% and 51.7%. Thus, these results showed that overall bone health of NG was better than that of NNG. Dietary balance and quality were also more satisfactory in NG. These results showed that noodle consumption may have an impact on the prevalence of chronic diseases.

This study was to evaluate the effectiveness of nutritional counseling for farmers by using computer- based program to estimate pre - and post - knowledge and attitude changes. The desirable change of both knowledge and attitude focused on improving food Intake and early easing of body complaints. 311 agricultural workers in Korea were chosen for this experiment. The score was compared by 2 methods. In the first method, the scores were calculated from nutrient intake quantity and indices. In the second method, the difference of pre and post test of nutritional counseling by count of correct answers of foods and food preparation attitudes was measured according to different body complaints status. Major farming type was rice-planting(39%). The consciousness of health status of the subjects of less than 50 years old was good(42%), but it was only 20% in over 50 years' group. Female farmers felt uncomfortable in body complaints. Their body complaints were 2 times more than the male farmers, particularly, in over 50 years group. Nutrient intakes were lower in male based on the KRDA, except for vitamin C, niacin, and phosphate. Female farmers' nutrient intake was adequate based on the KRDA, but was low in vitamin A, pyridoxin, and iron. From the scores of knowledge and attitude by pre and post tests, counseling was efficient In nutritional education of all age groups, especially the older ones. The effect of counseling by farming type showed that the real agricultural workers had more increased score In the post test. This results Indicated that counseling about food, nutrition. and health to these workers was always effective. Therefore nutritional counseling and education program should be developed for different kinds of health and nutrition. It would be conducted to promote food behavior and improve nutritional and health status of farmers.

Recently, Korea had virtually reached an FTA deal with China on November 10, 2014 after the 14 rounds of negotiation during past two and half years. The two countries agreed to the FTA's 22 chapters, including products, services, investment, e-commerce, finance, communication, and other trade issues, but rice and several sensitive agricultural and fisheries products were excluded from the deal. Korea and China will remove their import tariffs on more than 90 percent of all products and more than 85 percent of imports by value within 20 years once the FTA is implemented. This paper intends to analyze the impacts of Korea-China FTA on the major industries in Daegu-Gyeongbuk region. Considering the statistics on the bilateral trade between China and Daegu-Gyeongbuk region, import tariff rates of the two countries, trade specialization indices of the major industries, and the package of Korea-China FTA deal, this study investigated the sectoral effects of Korea-China FTA on the four main industries, textiles, electrical-electronics, machinery and auto parts, and steel and iron industries in that region.

This study was performed in order to identify nutritional factors affecting on skin sebum content with 131 female university undergraduates in 2003. We measured the sebum contents of 4 facial spots to classify their skin types. Daily energy and nutrient intakes of the subjects were not deficient except in calcium and iron, which were 466.2 mg (66.6% RDA) and 8.5 mg (53.4% RDA) relatively. We observed no significant difference of energy and nutrient intakes among the 3 skin types. But significantly higher consumption of grains and slightly higher frequencies of several food groups (excepting starches) were shown in oily skin types, so they might have higher nutrient intakes. Serum indices and food preferences mostly revealed no difference among the 3 skin types. But in the oily skin type, serum phosphorus levels were significantly lower than others, suggesting phosphorus-rich food consumption like soft drinks and pains could lead to a dry skin type rather than an oily one. Also in the oily skin type, sweet taste preference was slightly tower than others; more-over, sweet intake was lower samely significantly. There was mostly no significant relationship between facial sebum contents and nutrient intakes, dietary behavior, food frequency and food preference except in some factors. Animal protein intake showed a significant negative relationship toward facial sebum content. On the other hand, in normal skin type, Fishes consumed was slightly higher than others, so that higher animal protein consumption presumably leads to normal skin type. Frequency of fried food and bacon and preference of fried foods showed slightly negative relationships toward facial sebum content. Regular meal times showed significantly increased facial sebum content.

The purpose of this study was to understand the effects a mother's degree of obesity has on her daughter's obesity index, psychological well-being index, and nutrient intakes. The daughters, as study subjects, were classified into two groups according to their mother's body mass index (BMI): an obese group [BMI>25 kg/m$^2$, mother obesity group (MOG)] and a normal weight group [BMI<25 kg/m$^2$, mother normal weight group (MNG)]. The daughters in MOG showed significantly higher percent ideal body weight values than the daughters in MNG (p<0.001). MOG and MNG had significantly different psychological well-being index scores in terms of being classified into a highly stressed group (p<0.001), potentially stressed group (p<0.05), and healthy group (p<0.001). Intakes of daily energy, protein, fat, thiamin, riboflavin, niacin, phosphorus, and iron were also significantly different (p<0.001) between MOG and MNG. In particular, the vitamin A and C intakes of the MNG daughters were significantly higher than those of the MOG daughters (p<0.001). Overall, the results showed that a mother's level of obesity was essentially related to her daughter's obesity index, psychological well-being index score, and nutrient intakes. Therefore, it seems necessary for mothers to maintain an ideal body weight to prevent obesity and diet related problems in their daughters.

We studied the effects of intake of the steamed bean powder(SB) and chungkukjang powder(CK) on blood parameters such as glucose, albumin, GOT, GPT, hematocrit, hemoglobin, total-/HDL-/LDL-cholesterol and triglyceride, and blood antioxidant nutrients such as retinol, tocopherols and carotenes in 26 college women. There were 2 groups, one group had 13 participants who consumed 30g SP and second group (13 participants) consumed 30g CK daily for 4 weeks. The study compared before with after SP/CK intake. The average age of the participants was 22.1 years, there were no significant differences between the two groups in terms of all parameters before the study. The energy intake showed no significant differences between before and after SP/CK intake. C(carbohydrate) propotion was reduced, and P(protein) and F(fat) ratio were increased after 4 week intake of SP/CK. Indices of nutritional quality(INQ) of protein(p<0.01), iron(p<0.05), zinc(p<0.05), vitamin C(p<0.05) were significantly increased after SP intake, and those of protein(p<0.05) and zinc also increased after CK intake. There were no significant differences in TG, total-/HDL-/LDL-cholesterol before and after SP/CK intake. The CK intake group showed the reduction only in retinol level in blood(p<0.05). Some students reported the improvement of the constipation and the regularity of the bowel elemination, and some students experienced the prolongation effects on one's monthly days after SP/CK intake. In this study, we could see the effect of improvement in some nutrients intake, but no effect in blood parameters by SP/CK intake for 4 weeks. That reason might be that the participants were healthy young women, or the trail period was not enough long to change.

This study was performed to estimate the effect of alphacalcidol supplementation or nutrition education on the nutrient intakes, bone mineral density and bone markers in continuous ambulatory peritoneal dialysis (CAPD) patients. The 90 CAPD subjects were randomly assigned to 3 groups (alphacalcidol group: AG, nutrition education group: NG, and control group: CG). Alphacalcidol supplementation($0.5{\mu}g/day$) was carried out for 8 months. Nutrition counseling was performed according to the patient s individual question for the first 6 months and scheduled nutrition education with individual counseling was carried out for the last 2 months. In baseline data. there were no significant differences in age, sex, family number, education years and monthly income except the NG showed significantly less duration of CAPD (p< 0.05) compared to other two groups. After intervention all three groups showed tendency of lower intakes. NG revealed less decrease in protein, especially in animal protein calcium from Ca-P binder, dietary calcium, dietary iron and niacin. NG showed significantly more increase in dry weight (p<0.05) and AG in waist circumference (p<0.001) after intervention. The groups did not show significant differences in the changes of biochemical indices related to bone metabolism. NG revealed more increase in trochanter BMD(p < 0.05) compared to other two groups. It seems that nutrition education is more effective in preventing deterioration or improving the bone and general nutrition status.
