  • 본 연구는 노인과 여대생의 건강 상태를 비교하여 노화가 일어날수록 변화되는 신체 및 식습관 변화 등을 알아보고, 좀 더 효과적인 노인 건강 증진 및 그에 대한 기초 자료를 제공하고자 실시하였다. 본 연구의 여자 노인 평균 연령은 $78.64{\pm}7.30$세였으며, 신장과 체중은 각각 $147.07{\pm}5.72$ cm, $50.47{\pm}7.44$ kg으로 한국인 체위 기준치에 비해 3.93 cm 더 작았으나, 체중은 0.27kg 정도 높게 조사되었다. 체질량 지수는 노인이 $22.83{\pm}6.11\;kg/m^2$, 여대생이 $20.23{\pm}2.13\;kg/m^2$로 노인의 체질량 지수가 높았지만, 정상 범위($18.5\;kg/m^2{\leq}$BMI < 24.9kg/$m^2$)에 속하였다. 여자 노인의 경우, 아침식사를 여대생에 비해 챙겨 먹는 경우가 많았지만, 의치 등을 사용하고, 음식을 씹는데 어려움을 겪고 있어, 국물 위주의 식사를 하는 경우가 많았고, 식사시간도 10분 이내로 짧았다. 대부분의 여자 노인들이 한가지 이상의 질병을 앓고 있는 것으로 조사되었으며, 고혈압이 25%로 가장 많은 비율을 차지하였다. 운동 여부를 묻는 질문에는 여자 노인은 52.2%, 여대생은 47.8%가 운동을 한다고 답하였다. 운동의 횟수를 보면, 여자 노인은 35명 중 일주일에 평균 1~2번 정도 하는 경우가 74.3%나 되었다. 전체 조사 대상자의 1회 운동시 평균 운동 시간은 30분 이내가 가장 많은 비율(40.3%)을 차지하였고, 전체 조사 대상자가 가장 즐겨하는 운동의 종류로는 가벼운 운동(걷기, 체조 등)이 73.1%였으며, 그 다음으로 중정도의 운동(자전거, 헬스, 조깅 등)은 19.4%였다. 여대생의 경우에는 강도가 높은 운동(탁구, 수영, 테니스 등)을 하는 비율도 7.5%나 되었다. 여자 노인은 여대생에 비해 흡연과 음주율은 낮았지만, 몇몇의 노인의 경우 흡연과 음주를 장기간에 걸쳐한 것으로 조사되었다. 혈액 성상 중 여자 노인은 적혈구수, hemoglobin, hematocrit, MCV 등이 여대생에 비해 유의하게 낮았으나, MCH와 MCHC 수치는 오히려 여자 노인이 각각 $31.27{\pm}3.79$ pg (p<0.09)과 $33.96{\pm}1.11$ g/dL(p<0.05)로 여대생의 수치에 비해 높았다. 중성지방 수치는 여대생($79.71{\pm}40.96$ mg/dL)에 비해 여자 노인($127.89{\pm}51.25$ mg/dL)에서 수치가 유의하게 높았으며(p<0.05), LDL-cholesterol 수치도 여자 노인이 $120.51{\pm}32.88$ mg/dL, 여대생이 $103.78{\pm}22.94$ mg/dL로 나타나 여자 노인에서 유의하게 높은 수치를 보였다(p<0.05). 그러나 총 콜레스테롤과 HDL-cholesterol의 수치는 여자 노인에 비해 여대생에서 높은 수치를 보였다(p<0.05). 혈청내 vitamin C의 함량은 여자 노인이 $3.01{\pm}2.94\;{\mu}g/mL$, 여대생이 $4.96{\pm}4.89\;{\mu}g/mL$로 여대생의 수치가 유의하게 높았다(p<0.05). 본 연구 결과, 노인의 경우 노화가 진행될수록 몸의 기능의 쇠퇴로 인해 정상적인 생활을 하는 것이 많이 불편한 것으로 조사되었으며, 식습관 및 건강 상태 등이 급격히 변화 하고, 혈액내 중성지방, LDL-cholesterol 수치가 급격히 높아졌다. 또한 노인에게 있어서 노화를 지연시켜 주며, 항산화 역할을 하는 vitamin C와 HDL-cholesterol 수치가 낮아지는 것을 알 수 있었다. 따라서 노인들이 건강한 삶을 영위할 수 있는 실질적인 식생활 전반의 개선과 건강 증진을 위한 영양교육 강화의 필요성 및 노인 건강 상태에 알맞은 체계적인 식사 관리 프로그램이 요구됨을 알 수 있었다. 또한 자신의 건강 상태를 올바르게 판단하여 자신에게 맞는 식생활 계획을 세우는 것이 필요하다고 사료된다.

  • The purpose of this study was to investigate self-perception of health and body image, blood lipid profiles and nutrient intake of adolescents. The subjects were 686 adolescent boys (379 middle school students, 307 high school students) and 613 adolescent girls (272 middle school students, 341 high school students) in Incheon. This cross-sectional survey was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for triglyceride, total cholesterol and LDL- and HDL-cholesterol. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. Average age, height and weight of male middle school students were 13.8 years, 163.5cm, 56.0kg and those of male high school students were 16.5 years, 171.7cm, 64.3kg. In female, average age, height and weight of middle school students were 13.7 years, 157.1cm, 51.5kg and those of high school students were 16.6 years, 159.7cm, 56.8kg. Female middle school students perceived their health status significantly better compared to female high school students (p < 0.001). Female high school students perceived themselves significantly fatter compared to female middle school students (p < 0.05). Average TG level of female middle school students was significantly higher compared to female high school students (p < 0.01). Nutrient intakes of the male and female students except phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of male and female students were under the 65% of the Korean RDA. Therefore, proper nutrition education is required for Korean adolescents to encourage desirable food habits and maintain nutritional lipids status. (J Community Nutrition 5(1) : 3∼12, 2003)

  • Our previous studies showed that kisspeptin-10 (Kp-10) injected in vivo can markedly increase lipid anabolism in liver of quails. In order to investigate the direct effect of Kp-10 on lipid metabolism of hepatocytes in birds, cells were separated from embryos livers and cultured in vitro with 0, 100 and 1,000 nM Kp-10, respectively. The results showed that after 24 h treatment, cells viability was not affected by 100 nM Kp-10, but showed a mild decrease with 1,000 nM Kp-10 compared to the control cells. Based on the results of the cell viability, 100 nM dosage of Kp-10 was selected for the further study and analysis. Compared with control cells, total cholesterol (Tch) contents in 100 nM treated cells were increased by 51.23%, but did not reach statistical significance, while the level of triglyceride (TG), high density of lipoprotein-cholesterol (HDL-C) and low density of lipoprotein-cholesterol (LDL-C) were significantly increased. Real-time PCR results showed that ApoVLDL-II mRNA expression had a tendency to increase, genes including sterol regulatory element-binding protein-1 (SREBP-1), acetyl coenzyme A carboxylase ${\alpha}$ ($ACC{\alpha}$), carnitine palmitoyltransferase 1 (CPT1), 3-hydroxyl-3-methylglutaryl-coenzyme A reductases (HMGCR) and stearyl coenzyme A dehydrogenase-1 (SCD1) mRNA in hepatocytes were significantly down-regulated by 100 nM Kp-10. However, contrary to its gene expression, SREBP-1 protein expression was significantly up-regulated by 100 nM Kp-10. Some of the significant correlations in mRNA expression were found between genes encoding hepatic factors or enzymes involved in lipid metabolism in liver of birds. These results indicate that Kp-10 stimulates lipid synthesis directly in primary cultured hepatocytes of chickens.

  • The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n=371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P<0.05) and with serum triglyceride (TG) levels in women (P<0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P<0.05) and serum TGs (P<0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults.

  • 에폭시 경화계에서 말단 관능기가 같은 선형아민 경화제의 주쇄에 포함된 에틸기에 결합된 질소원자 개수가 반응특성 및 열적, 기계적특성에 미치는 영향을 알아보기 위하여, 빈용 에폭시수지인 DCEBF (diglycidyl ether of bisphenol F)를 DETA (diethylenetriamine), TETA (triethylenetetraamine) 그리고 TEPA (tetraethylenepentaamine)와 1:1 당량비로 경화하였다. 이 연구에서 DGEBF/아민계에서 경화제 주쇄의 질소원자 거수에 의하여 반응특성 및 열적성질, 기계적특성에 중대하게 영향을 미쳤다. 즉, 주쇄의 질소원자 개수가 작을수록 반응열이 많고 최대발열온도가 낮아졌다. 경화물의 경우 밀도와 최대반응전환률은 주쇄의 질소원자 개수와는 큰 관계가 없으나, 굴곡탄성률과 인장탄성률은 주쇄의 질소원자 개수가 작을 수록 크다. 그 외의 열안정성, 부피수축률(%), 유리전이온도, 인장강도, 굴곡강도는 주쇄의 질소원자 개수와는 일견 무관한 불규칙한 경향을 보인다. 이는 최대반응전환률(%)의 차이가 이러한 특성에 영향을 미치는 것을 나타낸다.

  • New types of protocols have been recently in development, all based on an absorbed dose-to-water with the aim of improving the accuracy of measurements of absorbed dose to water. IAEA TRS-277, the air-kerma standard-based present protocol, and IAEA TRS-398 and AAPM TG-51, the absorbed dose-to-water standard-based new one, were studied and compared theoretically and experimentally for photon beams of 6, 10, and 15 MV. NE 2571 and 3 Farmer types of ionization chambers in widely commercial use were used to determine an absorbed dose to water at the reference depth in water. Two different kinds of calibration factors were given respectively for every chamber calibrated in $\^$60/CO gamma ray beams from a Korean Secondary Standard Dosimetry Laboratory (KFDA). This work shows that there is around 1 % of difference of absorbed doses measured between two different types of calibration systems owing to different physical parameters and reference conditions used. We hope this work to help form the basis on development of new type of protocol in Korea.

  • Purpose: The purpose of this study was to examine the effects of a 12 week walking program on the risk factors associated with metabolic syndrome in older people in rural areas. Method: A total of 31 people among the people who live within the area served by E County Community Health Practice were observed from December 5, 2006 to February 23, 2007. This group included 18 people who were identified as having metabolic syndrome on the basis of the Asia-Pacific fatness basic standard (the experimental group) and a control group of 13 people who did not have metabolic syndrome. Results: The results of the study are as follows: In the experimental group, there was no significant difference in body composition between pre and post measurement. The small change in values that were observed in the experimental group did not reach statistical significance. However, body composition values in the control group increased. In the experimental group, there were significant differences in waist circumference, blood pressure, HDL-C, and fasting blood sugar between pre and post measurement. But there were no changes in the control group. There was no difference in TG in either group. As to changes in risk-factors related metabolic syndrome after the 12 week walking program, the number of risk-factors were effectively reduced in the experimental group, but not in the control group. Conclusion: According to the present study, a 12 week walking program led to significant improvement in body weight, BMI as the factors composing the body and in waist circumference, HDL-C, blood pressure, and fasting blood sugar as risk-factors related to metabolic syndrome in older people in rural areas.

  • Effects of garlic powder supplementation on blood lipid profile and antioxidant system were investigated in rats with and without swimming exercise. Sprague-Dawley rats of four experimental groups were fed for 4 weeks diets containing $15\%$ beef tallow and $1\%$ cholesterol; control without garlic and exercise, Go with $2\%$ garlic alone, Ex with exercise alone, GoEx with $2\%$ garlic and exercise. Rats were trained 40 min a days a days a week. Group Ex and GoEx showed significant lowering in body weight gain and fat accumulation. In Go, Ex and GoEx, plasm TG and LDL-C were lower and HDL-C was higher, although not significantly, compared to levels in control. Total cholesterol was significantly reduced in group Go, and Ex and GoEx were lower than control. The total/HDL cholesterol ratio was also found to be significantly different, decreasing the ratios in Go, Ex and GoEx. The hepatic TBARS increased significantly in group Ex $(51.7{\pm}3.43nM/g\;liver)$, while TBARS in Go and GoEx were low $(35.68{\pm}3.61,\;39.30{\pm}5.55nM/g\;liver)$ and similar to control's one. The activity of hepatic SOD in Go and GoEx tended higher than control and Ex without garlic. The hepatic catalase showed significantly the highest activity in Go. Activity of GSH-px was significantly low in Ex with $0.14{\pm}0.03$ unit/mg protein, and control, Go and GoEx had higher activities of $0.23{\pm}0.08,\;0.20{\pm}0.07,\;0.22{\pm}0.01\;unit/mg$ protein, respectively. Lower activities of antioxidant enzymes in Ex are likely to associated with the highest level of TBARS. It seems that a decrease in TBARS in GoEx relative to Ex was related to the increase in GSHpx and SOD with garlic supplemented, which led to compensate the oxidative stress from exercise. The results suggests that exercise or garlic supplement exerts blood lipid attenuating effect. In adition, garlic supplementation could strengthen the antioxidant potential against exercise-induced oxidants, partly by modulating oxidant enzyme activity. These effects of garlic may make it a beneficial agent on CVD.

  • LSM powder material for an oxygen-electrode(anode) of High Temperature Steam Electrolysis (RISE) was synthesized by a Modified-Glycine nitrate process(GNP). Amount of nitric acid and its concentration was varied to find out an appropriate composition for the oxygen-electrode(anode). In order to optimize the amount of Glycine used as an oxidant of self-combustion process, the ratio of Glycine to Anion was varied. $La_{0.8}Sr_{0.2}MnO_3$, $La_{0.5}Sr_{0.5}MnO_3$, and $La_{0.2}Sr_{0.8}MnO_3$ were synthesized in this study. Those LSM were dried for overnight to remove moisture from the material at $110^{\circ}C$ and were calcined 2 hours at $650^{\circ}C$ and were sintered in a furnace for 5 hours at $1400^{\circ}C$. Their structures, surface morphologies, surface areas, and weight changes were investigated with XRD, SEM, BET, and TG/DTA. The best perovskite phase for the oxygen-electrode of HTSE was obtained with $La_{0.8}Sr_{0.2}MnO_3$ formula in which 100 ml of 3M nitric acid was used in the preparation of its formula. The optimized ratio of Glycine to Anion was 2.

  • Objectives: The purpose of this study is to identify prevalence and related factors of the elderly, who took health examination, with metabolic syndrome. Methods: The health examination and lifestyle survey were performed for 21,512 adults at 60 years of age or older who took health examination in H health promotion center during January-March 2009. Results: The prevalence of metabolic syndrome for the subject was 24.0%. Of the subject with metabolic syndrome, the prevalence of the diseases was obesity 60%, abdominal obesity 78.5%, hypertension 82.6%, dyslipidemia 89.7% and diabetes 51.9%. In comparison of the relationship between metabolic syndrome and other diseases, the male subject with metabolic syndrome were significantly higher in BMI, waist circumference, systolic/diastolic blood pressure, hemoglobin, AST, ALT, $\gamma$-GTP, TG, AC glucose, creatinine than normal male(p<0.001). In comparison of the relationship between metabolic syndrome and lifestyle, more drinking frequency and amount in male and more drinking frequency in female were associated with increased risk of metabolic syndrome(p<0.01). Regardless of exercise intensity, practice of exercise contributed to reduce the risk of metabolic syndrome(p<0.01). Conclusion: In conclusion, TLC program, focused on lifestyle behaviors which is strongly associated with the prevalence of metabolic syndrome, should be developed for the improvement of life quality in the elderly with metabolic syndrome.
