The results that research industrial competitive power of about two hundreds frames manufactures were as follows. First, It's researched that frames industry of Daegu will be worse and worse, and 79 percent of inquiry manufactures in export and 58 percent of them in the domestic demand prospects to be worse. Second, it is analyzed that the commercial profits in 2004 was more decreased to 16.5 percent than 2002. Therefore it is studied that they will be diminished to 5---- comparing with last year by a fall in the exchange rate of the won dollar, in the export unit cost and a raise of raw material price. Third, it is researched that most competitive countries of Daegu glasses manufactures is China and the mext county is japan, ltuly and hik. Fourth, It is studied that average price of glasses of Daegu during last three years(2002~2004) was more disadvantageous than China and Hong Kong, but was more profitable than Italy and Japan by the examination that when Korea is 100, China is 82, Hong Kong 89, Italy 112, Japan 114. Fifth, It is investigated that the average of production cost in Daegu is more disadvantageous than that of China and Hong Kong but is more profitable that of Italy and Japan by the study that when average production cost of Korea is 100, that of China is 78 and that of Hong Kong 89, that of Italy 114. Sixth, It is studied that the Average personal expense of Daegu is much more disadvantageous than that of China and more profitable than Japan and Italy by the analysis that when Korea is 100, China is 74, Hong Kong 98, Japan 112, Italy 113. Seventh, It is analyzed that technique, quality, design of Daegu are more advantageous than those of China, are equal with those of Hong Kong. Eighth, It is studied that Daegu still lags behind more four and five years than developed countries and goes more oheod four years than developing countries.

Purpose : We performed the study to evaluate the value of the follow-up echocardiogram performed 6 months to 1 year after the onset of Kawasaki disease(KD), as recommended by American Heart Association(AHA) guidelines, when echocardiograms in the convalescent period were normal. Methods : Patients were selected from 147 cases diagnosed with KD at Pusan Paik hospital from January 2000 to October 2003. A total of 45 KD patients belonged to AHA risk level I and II were performed follow-up echocardiography. The patient's medical records and echocardiogram were reviewed. Additionally, we sought the opinion of pediatric cardiologists on the subject by means of a multiple-choice survey. Results : 37 children were belonged to AHA risk level I and the remaining 8 patients were belonged to risk level II. Of these 45 children, none were noted to have abnormalities on later follow-up echocardiogram. In the results of questionnaire, 37 percent of the participants advocate no follow-up after convalescent period for risk level I, and 33.3 percent favor periodic follow-up with echocardiography for risk level II up to one year. But there were no consensus about the diagnostic criteria of coronary abnormalities and how to follow-up these patients. Conclusion : All children with KD should have an echocardiogram at present and a follow-up study 6 to 8 weeks after the onset of fever. However, additional echocardiographies are not justified if the 6- to 8-week follow-up echocardiogram is normal. We would recommend that the more reasonable diagnostic criteria for coronary abnormalities and the Korean guidelines for long-term cardiovascular management and follow-up of KD need to be established.

Purpose : A human milk bank collects, processes, eliminates, and stores breast milk from donors and provides breast milk to those in need. The authors hereby present the experiences and the objective lessons obtained through operating a nationwide human milk bank over a period of 2 years. Methods : The characteristics of the donors and the recipients and the amounts of breast milk donated, processed, and received at the East-West Neo Medical Center Human Milk Bank were investigated from August 2007 to August 2009. Results : The donor pool consisted of 131 first-time donors and 39 repeat donors who made 341 and 127 donations, respectively. Seventy-nine percent of the donors resided in the Seoul-Kyunggi area, and 60% of the donors were in their 30s. Most information and motivation came from the Internet (66%) or television (14%). A total of 2,736 L of breast milk was collected, and 1,979 L were processed. The cumulative number of recipients was 160 preterm or full-term infants and 21 adults, each group receiving the breast milk 337 and 41 times, respectively. In total, infants received 1,663 L and adults received 179 L. Conclusion : Through the present study, the role and importance of a human milk bank in collecting, pasteurizing, and storing surplus breast milk in through sanitary, medically proven methods and providing this breast milk to recipients could be appreciated and reevaluated. The authors believe that a national support system is necessary to expand this practice to a nationwide scale.

Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency disease which is characterized by high serum IgE levels, eczema, and recurrent infections. Herein we present the case of a patient with HIES associated with STAT3 gene ($stat3$) mutation. A 16 year-old girl was admitted to our hospital due to hemoptysis caused by pneumonia with bronchiectasis. She had a history of recurrent skin and respiratory tract infections, such as pneumonia caused by MRSA (methicillin-resistant $Staphylococcus$ $aureus$) and $Pseudomonas$ $aeruginosa$. On physical examination, a broad round shaped nose, oral thrush, and chronic eczematous skin rash over her whole body were found. Laboratory data showed an elevated eosinophil count ($750/{\mu}L$) and total IgE level (5,001 U/mL). The patient's National Institutes of Health (NIH) score for HIES was 44. Direct sequencing of the STAT3 gene revealed that the patient was heterozygous for a missense mutation in the DNA binding domain of the STAT3 protein (c.1144C>T, p. Arg382Trp). HIES should be suspected in patients with recurrent infections and can be confirmed by clinical scoring and genetic analysis.

The aim of the present study was to investigate the effect of combined extract of safflower seed with herbs on the improvement of blood glucose, lipid peroxides, lipids in the plasma and liver of strpetozotocin-induced diabetic rats. Rats in the experimental group were orally administered with combined extract of safflower seed (100 mg, 200 mg/kg B.W.) with herbs (Ophiopogon japonicus Ker-Gaqler, Glycyrrhiza uralensis Fisch, Mori Folium, Poria cocos, Rehmannia glutinosa, Eriobtrya japonica, Aralia continentalis Kitagawa, Zizyphus jujuba var, Cornus officinalis, Paeonia suffruticosa, Trichosanthes kirilowii Maxim and Schizandra chinensis Baill) for 4 weeks. Body weight gain and food efficiency ratio were significantly lower in diabetic groups than those of control group. These were no protective effect of the supplementation of combined extract of safflower seed with herbs. Concentration of blood glucose was significantly higher in the diabetic groups than those in the control group. Blood glucose concentration was remarkably lower supplementation of combined extract of safflower seed (200 mg/kg B.W.) with herbs. There was no significant difference of plasma lipid peroxides among experimental groups, while liver lipid peroxides of diabetic group was significantly higher in control group. But supplementation of combined extract of safflower seed with herbs was induced markedly lower in liver lipid peroxides in diabetic rats. Diabetic groups had markedly higher levels in triglycerides, LDL-cholesterol and atherogenic index, while had lower HDL-cholesterol level. Triglyceride levels of plasma and liver were significantly lower with combined extract of safflower seed with herbs. But total cholesterol, phospholipid and free fatty acid were no differing significantly among experimental groups.

To assess trans fatty acids (tFAs) intake of middle school students in Busan, behavior of having meals and 3 day's food record were surveyed in 800 subjects. 35.3% of subjects responded to twice a day in frequency of snack intake. Preferred snack items were ice cream (68.6%) and milk (57.0%). Subjects of dining out preferred jajangmyon (54.6%), seasoned chicken (50.5%), fried chicken (35-3%) in order when dined out. Mean daily tFAs intake of subjects was 1.68$\pm$0.04 g. Mean daily intake level of girls was 1.89$\pm$0.06 g which was significantly higher than that of boys, 1.40 $\pm$ 0.05 g (p<0.001). Naturally derived tFAs intake was 1.04$\pm$0.03 g which corresponded to 62.1% of total tFAs intake per day and industrially derived tFAs intake was 0.64 $\pm$ 0.02 g, 37.9% of total tFAs intake per day. Calorie percentage of tFAs was 0.8% and fat percentage of tFAs was 3.16%. The level of tFAs intake showed a significant difference with monthly allowance (p<0.05) and frequency of snack intake (p<0.001) in girls, which was not the case in boys. The main sources of tFAs were milk and dairy products (34.3%), bakeries (18.3%), and fish and meat products (16.2%), in order. From above results, we can conclude that tFAs intake of middle school student is not as much as that of Western teenagers. However, exact estimation of tFAs intake requires database of tFAs in broad range of processed foods commonly consumed in Korea.

Effects of maltogenic amylase on textural properties of dough and quality characteristics of white pan bread were investigated. White pan bread was prepared with four different levels of maltogenic amylase contents (M-1: 0.048 U/g, M-2: 0.060 U/g, M-3: 0.072 U/g, M-4: 0.084 U/g). The setback by amylograph for the control was $480.0{\pm}12.25$ Brabender Unit (B.U.) while M-4 showed the a setback of $215.0{\pm}5.00B.U.$ The absorption, mixing tolerance index, and stability by farinogram were not significantly different (P>0.05) for across all treatments. The area under the curve (135 min) by extensogram was higher than all samples. The texture profile analysis results showed that there was significant decreasing in hardness for the maltogenic amylase infused bread (P<0.05). M-3 and M-4 showed higher springiness and cohesiveness but lower hardness than control over 1 to 3 days, indicating possibly extended shelf-life. Imaging scan showed that air cell size less than $0.4mm^2$ for the control and M-4 were at rates of 94.90% and 95.70%, respectively. For sensory evaluation, M-3 and M-4 showed higher intensities than the control for taste, flavor, texture, mouthfeel, and moistness quality. These results imply that the quality of white pan bread could be improved by adding maltogenic amylase without the use of chemical additives.

The aim of this study was to investigate the physicochemical characteristics of commercial Mukeunji product along with its sensory properties. Six different types of commercial Mukeunji products were purchased through an on-line market, and each product had a different fermentation period. General commercial Baechu Kimchi was compared with commercial Mukeunji products in order to standardize quality properties of Mukeunji. As a result, commercial Mukeunji showed a lower pH value (pH 3.96, mean value) than commercial Baechu Kimchi (pH 5.92), whereas commercial Mukeunji samples showed higher acidity and salinity. Color values (L, a, and b) of commercial Mukeunji decreased as the storage period increased. Hardness and thickness of commercial Mukeunji showed a lower range compared to Baechu Kimchi. The reducing sugar content decreased as the storage period of commercial Mukeunji increased. Acetic, lactic, and succinic acids were detected in commercial Mukeunji samples, whereas citric acid and malic acid were additionally detected in Baechu Kimchi. Commercial Mukeunji samples showed lower contents of acetic and succinic acid and higher content of lactic acid than Baechu Kimchi. Commercial Mukeunji samples showed a significant difference in all descriptive sensory attributes except for bitterness. Overall intensity, sourness, moldy odor, redness, sour smell, saltiness, and carbonated taste increased as the storage period increased, whereas cabbage flavor, crispiness, sweetness, firmness, and savory taste decreased as the storage period increased.

In order to develop new immuno-stimulating ingredients from mature leaves of green tea, crude polysaccharides were isolated from pectinase digests of tea leaves (green tea enzyme digestion, GTE-0), after which their immuno-stimulating activities and chemical properties were examined. GTE-0 mainly contained neutral sugars (54.9%) such as glucose (14.2%), arabinose (12.2%), rhamnose (11.1%), and galacturonic acid (45.1%), which are characteristic of pectic polysaccharides. The anti-complementary activity of GTE-0 was similar to that of polysaccharide K (used as positive control). Number of morphologically activated macrophages was significantly increased in the GTE-0-treated group. GTE-0 significantly augmented $H_2O_2$ and reactive oxygen species production by murine peritoneal macrophage cells in a dose-dependent manner, whereas production of nitric oxide showed the highest activity at a dose of $100{\mu}g/mL$ among all tested concentrations. Murine peritoneal macrophages stimulated with GTE-0 showed enhanced production of various cytokines such as interleukin (IL)-6, IL-12, and tumor necrosis factors-${\alpha}$ in a dose-dependent manner. Further, GTE-0 induced higher phagocytic activity in a dose-dependent manner. In ex vivo assay for cytolytic activity of murine peritoneal macrophages, GTE-0-treated group showed significantly higher activity compared to the untreated group at an effector-to-target cell ratio of 20. The above results lead us to conclude that polysaccharides from leaves of green tea have a potent immuno-stimulating effect on murine peritoneal macrophage cells.
