The purpose of this study was to investigate the effect of routine jogging exercise on cardiorespiratory function and blood lipid and urine components change in 40 year's Korean men. The subjects consisted of 20 middle-aged routine jogging group participated 30~40 min at 70% of the heart rate max 3-4 days per week 1 year more and 20 control group. The results of this study were as follows; 1. The HR rest was decreased and HR max was increased by routine jogging group while no significance existed. Vo_(2) max was significantly increased in routine jogging grouP(p<0.05) while SBP and DBP were not changed. 2. Fat% was not significantly decreased in jogging group. 3. pH in urine showed no change among the jogging group, but the control group showed a slight change from 5.0 to 7.2. For the control group, specific gravity (S.G.) was 1.018 at rest, 1.029 after exercise, for the jogging group specific gravity was 0.1818 at rest, 1.022 after exercise. 4. The protein change was negative for all subjects but two of them was trace after exercise. The change of glucose, bilirubin, urobilinogen, and ketone body was also normal for all subjects before and after exercise. This result indicate that routine jogging exercise decreases the risk of degenerative disease. 40 year's middle-aged man must improve theircardiorespiratory function to protect and recover degenerative disease.

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.

Wie Seung-Hee,Shanklin Carol W. The Korean Society of Community Nutrition 2006 Journal of community nutrition Vol.8 No.1

This retrospective study was designed to evaluate the nutrient contributions of the five meal components of school lunch menus planned for elementary students in two school districts (District A and B) in the Midwestern state of the United States. The 4-week cycle menu was planned for two time periods (Period 1 and Period 2) following guidelines for NuMenus and general menu planning principles. Menu components of planned and served menus for two time periods were analyzed using $Nutri-Kids^{TM}$. No significant differences in the nutrient content of between Periods 1 and 2 were found for District A. District B served significantly more vitamin A and total fat in Period 1 and significantly more calories, iron, vitamin A, protein, and total fat in Period 2 than was planned. The major nutrients provided by the entree component included protein, calories, cholesterol, total fat, saturated fat, and sodium. Milk was an important source of calcium and provided approximately one-third of the total protein and vitamin A in the meal. The vegetable/fruit component was the major source of vitamins A and C. The grain/bread component provided approximately 20% of the carbohydrates among five meal components. The miscellaneous component affected the sodium and fat content of the menus. Menu planners can use the results of this study to enhance their knowledge of the nutrient contributions of each meal component and as inputs for planning menus that meet children's nutritional requirements.

Preferences of U.S. consumers for setting quality factors of Bibimbap

Seo, Sang-Hee,Kim, Eun-Mi,Kwock, Chang-Keun,Wie, Seung-Hee Korean Society of Food Culture 2012 韓國食生活文化學會誌 Vol.27 No.1

The purpose of this study was to identify U.S. consumers' preferences for Bibimbap and to determine whether or not Bibimbap can be adopted into the American palate. A total of 214 people tasted a controlled amount of Bibimbap and Gochujang sauce (red chili pepper sauce) and then completed a preference test. Bibimbap was highly rated overall in the areas of appearance, color, smell, and taste. Gochujang sauce was also well-accepted in terms of taste and spiciness. Most of the participants disliked the seaweed and shiitake mushrooms, which means that Bibimbap can improve its garnish taste and aroma by removing them. Further, a more watery sauce was served as foreigners are not familiar with mixing food culture. Therefore, by offering diverse ingredient options, the acceptance of traditional Bibimbap can be increased in the U.S.

Improving Solubility through Carboxymethylation of Different-sized Endosperm, Bran, and Husk Rice Powders

Kyeong Ok Choi,Seung Cheol Yang,Dong Eun Kim,Wie-Soo Kang,Malshick Shin,Yoon-Hee Choi,Sanghoon Ko 한국식품과학회 2009 Food Science and Biotechnology Vol.18 No.6

The surfaces of different-sized endosperm, bran, and husk rice powders were modified using carboxymethylation. Carboxymethylation was carried out using aqueous alkalization and neutralization. After the carboxymethylation process, the centrifuged products were milled and classified by size: particles passed through sieves of 45, 106, and 300-㎛ width. The effect of carboxymethylation on physical properties such as solubility and dispersibility of endosperm, bran, and husk particles were studied. Overall, carboxymethylation increased solubility of the particles, while size reduction increased dispersibility. In particular, carboxymethylation created good aqueous suspensions by minimizing interparticle agglomeration. Our results show that the combination of size reduction and carboxymethylation improves solubility and dispersibility, resulting in better stability of the suspension. This study may be helpful for expanding the use of rice and its byproducts as ingredients in a variety of food and beverage applications.

[ $Entr{\acute{e}}e$ ] Popularity Affects Nutrient Intake among School-Aged Children Eating School Breakfasts

An Min-Y.,Shanklin Carol W.,Wie Seung-Hee The Korean Society of Community Nutrition 2006 Journal of community nutrition Vol.8 No.2

The purposes of this study were to investigate the effects of the popularity of menu items in nutrient consumption of school-aged children participating in a School Breakfast Program. The weighed plate waste method was used to determine the nutrient intake of students. The nutrient intake was evaluated based on the popularity of the menu item, gender, and grades. The average intakes of all nutrients except energy, fiber, and sodium were well within the goals. Actual nutrient intake varied based upon the popularity of $entr{\acute{e}}es$ and the popularity of menu items was a main effect in nutrient content of meals. When the most popular $entr{\acute{e}}es$ were served, school-aged children's energy intake and School Breakfast Program participation rate increased. Saturated fat and sodium intakes also were higher than the goal when the most popular $entr{\acute{e}}es$ were served. The significant main effect was grades for total fat (p < 0.05) and calcium (p < 0.05), which was qualified by the two-way interaction between gender and grades for saturated fat (p < 0.05), protein (p<0.1), iron (p<0.01), vitamin C (p<0.01) and carbohydrates (p<0.001). Gender itself was not a significant main effect. Based on the findings, the suggestions for educating school-aged children on more healthful breakfast food choices and reformulating recipes for the popular $entr{\acute{e}}es$ are made.

능동 탭은 BVI 소음 저감을 위한 능동제어 기술 중 하나이며, 이를 이용한 소음 저감효과에 대한 해석은 기술 개발에 있어서 매우 중요한 과정의 하나이다. 능동 탭의 소음저감 성능 분석을 위하여 모델 로터시스템에 대한 구조 설계를 수행하고 CFD 해석을 통해 에어포일 공력 데이터를 생성하였으며, 이를 이용하여 통합해석 프로그램인 CAMRAD Ⅱ 모델을 구성하였다. 하강 비행 상태에서 능동 탭을 HHC 방법으로 작동할 경우 로터에서 발생되는 공력 하중을 CAMRAD Ⅱ를 이용하여 계산하고, 이에 따른 BVI 소음 변화를 자체 소음해석 프로그램으로 계산하였다. 능동 탭의 작동 길이 및 제어 위상의 변화에 따른 소음해석 결과 최대 -3.3㏈의 BVI 소음 저감 효과를 얻을 수 있었다. Active tab is one of the promising technology for the BVI (blade-vortex interaction) noise reduction, and analysis of noise reduction performance is very important phase of the technology development. For the purpose of analysing the performance of noise reduction using active tab, CAMRAD Ⅱ model for a model-scale rotor system was constructed utilizing structural design result and airfoil aerodynamic data generated by CFD (computational fluid dynamics) calculation. HHC strategy was applied to descent flight condition and air-load was calculated by CAMRAD Ⅱ then variations of BVI noise was calculated by in-house program. Calculation result with respect to tab length and control phase changes showed BVI noise could be reduced by -3.3㏈.

<P><B>Purpose</B></P><P>Bacteremia is a major infectious complication associated with mortality in liver transplant recipients. The causative organisms and clinical courses differ between medical centers due to variations in regional bacterial epidemiology and posttransplant care. Further, living donors in Korea contribute to 83% of liver transplants, and individualized data are required to improve survival rates.</P><P><B>Patients and Methods</B></P><P>We retrospectively analyzed 104 subjects who had undergone living-donor liver transplant from 2005 to 2007.</P><P><B>Results</B></P><P>Among the 144 consecutive living-donor liver transplant recipients, 24% (34/144) developed bacteremia, 32% (46/144) developed non-bacteremic infections, and 44% (64/144) did not develop any infectious complications. Forty episodes of bacteremia occurred in 34 recipients. The major sources of bacteremia were intravascular catheter (30%; 12/40), biliary tract (30%; 12/40), and abdomen (22.5%; 9/40). Gram-positive cocci were more common (57.5%; 23/40) than Gram-negative rods (32.5 %; 13/40) and fungi (10%; 4/40). The data revealed that the following factors were significantly different between the bacteremia, non-bacteremic infection, and no infection groups: age (<I>p</I> = 0.024), posttransplant hemodialysis (<I>p</I> = 0.002), ICU stay (<I>p</I> = 0.012), posttransplant hospitalization (<I>p</I> < 0.0001), and duration of catheterization (<I>p</I> < 0.0001). The risk factors for bacteremia were older than 55 years (odds ratio, 6.1; <I>p</I> = 0.003), catheterization for more than 22 days (odds ratio, 4.0; <I>p</I> = 0.009), UNOS class IIA (odds ratio, 6.6; <I>p</I> = 0.039), and posttransplant hemodialysis (odds ratio, 23.1; <I>p</I> = 0.001). One-year survival rates in the bacteremic, non-bacteremic infection, and no infection groups were 73.2%, 91.3%, and 93.5%, respectively.</P><P><B>Conclusion</B></P><P>Early catheter removal and preservation of renal function should focus for improving survival after transplant.</P>
