This study was conducted to investigate the dietary intake, anthropometric data, and association between two factors and main food sources contributing macronutrients for overweight and obese females. Subjects were 85 adult females (overweight : 28, obese 57) where mean age was 38.7y. The results are summarized as follows. Mean fat percent, BMI, obesity rate were 29.3, 23.9 and 15.1%, respectively for overweight women and 32.7, 28.3, 36.4%, respectively for obese women. There were significant differences for most of the anthropometric data between groups. Fat percent for all subjects was significantly correlated with weight, waist circumference, hip circumference, mid arm circumference or skinfold thickness for the triceps, subscapular and suprailiac (p < 0.001). The parameter which showed the highest correlation coefficient (r=0.6156) with fat Percentage was the waist to hip ratio. Any significant differences were not found in dietary intake of nutrients or in diet composition between groups. The mean energy intake was 2090.1kcal (104% of RDA) for overweight women and 2113.0kcal (106% of RDA) for obese women. PFC ratio for overweight was 17 : 24 : 59 and 18 : 23 : 58 for obese subjects, which can be regarded as higher fat and lower carbohydrate percentages compared to recommended PFC ratio (15 20 65) .4) Fat intake was positively correlated (r : 0.2301, p < 0.05) with the triceps skinfold thickness, protein intake was also positively correlated with waist circumference (r=0.2668, p < 0.05) or fat weight(r: 0.2406, p < 0.05) .5) The main food items that contributed to energy intake for overweight or obese subjects were similar (rice, pork, bread, grapes, barley) except com oil in overweight or instant noodle for obese group. The subjects in this study were taking less energy from rice and more energy from pork and bread than women from 98 National Health and Nutrition Survey. Because there were no significant differences of dietary data between overweight and obese group, further investigation considering basal metabolic rate or activity would be needed.

This study was undertaken to examine the effect of ethanol on $Na^+ -dependent$ phosphate $(Na^+-P_i)$ uptake in opossum kidney (OK) cells, an established renal proximal tubular cell line. Ethanol inhibited ^Na^+-dependent$ component of phosphate uptake in a dose-dependent manner with $I_{50}$ of 8.4%, but it did not affect $Na^+-independent$ component. Similarly, ethanol inhibited $Na^+-dependent$ uptakes of glucose and amino acids (AIB, glycine, alanine, and leucine). Microsomal $Na^+-K^+-ATPase$ activity was not significantly altered when cells were treated with 8% ethanol. Kinetic analysis showed that ethanol increased $K_m$ without a change in $V_{max}$ of $Na^+-P_i$ uptake. Inhibitory effect of n-alcohols on $Na^+-P_i$ uptake was dependent on the length of the hydrocarbon chain, and it resulted from the binding of one molecule of alcohol, as indicated by the Hill coefficient (n) of 0.8-1.04. Catalase significantly prevented the inhibition, but superoxide dismutase and hydroxyl radical scavengers did not alter the ethanol effect. A potent antioxidant DPPD and iron chelators did not prevent the inhibition. Pyrazole, an inhibitor of alcohol dehydrogenase, did not attenuate ethanol-induced inhibition of $Na^+-P_i$ uptake, but it prevented ethanol-induced cell death. These results suggest that ethanol may inhibit $Na^+-P_i$ uptake through a direct action on the carrier protein, although the transport system is affected by alterations in the lipid environment of the membrane.

The purpose of this survey was to investigate the nutrient and food intake and food habits of the aged Jeju island. The survey was conducted to 102 persons, 50 persons aged 65 to 74 years and 52 persons aged 75 years over from July 5 to 25, 1981. The result obtained was summarized as follows; 1. Average nutrient intake per day Calorie intake was 1408 ㎉(which was 64% of RDA) for male and was 1343 ㎉ (84%) for female aged 65 to 74 years. For male aged 75 years over calorie intake was 1316㎉ (60%) and for female was 1292㎉ (81%). According to the intake of calorie, the ratio of carbohydrate, protein, fat, were average 74.8%, 15.1%, 10.1%. Protein intake was insufficient quantiatively, but the proportion of animal protein to total protein intake were 26.1 to 33.5%. Other nutrient intake, such as Ca, vitamin A and C were lower than the recommended dietary allowance. 2. Food intake In per capita food consumption were 69.1g to 744.7g and average 320.1g of cereal (125.1g of rice and 160.5g of barley) and 63.9g of fishes. Total food consumption and vegetables were diminished by older age. 3. Correlation assessment The correlation coefficient between residental stus lived with family, high activity, good health, and nutrient intake were significant (P<0.05). Poor teeth had influence on less nutrient intake, but was not significant. 4. Food preferences Food liked over 70% of subjects were persimmon, fishes, leef, tomato, and boiled rice with barley, etc. owing to tender food, economical reasons, seasonal influence, and food habits. Food disliked over 20% of subjects were instant noodle, small sardin, boiled rice, and ice-crea, etc. The majority of subjects had never had the processing food, such as ham, sausage, butter and margarine, etc.

The purpose of this study was to determine the reliability and validity of the fear-avoidance beliefs questionnaire (FABQ) in assessing Korean patients with low back pain. We performed translation and cross-cultural adaptation of the questionnaire and enrolled 52 patients (18 males and 34 females) with low back pain. The subjects completed a standardized self-administered questionnaire that included the FABQ assessment along with evaluations for the visual analogue scale (VAS), Oswestry disability index (ODI), self-rating anxiety scale (SAS), and Beck depression inventory-Korean version (K-BDI). The reliability of the obtained data was determined by evaluating the internal consistency on the basis of the intraclass correlation coefficient (ICC) and the Cronbach's alpha values, while the validity of the data was examined by correlating the FABQ scores to the VAS, ODI, SAS, and K-BDI scores. The translated versions of the FABQ showed good test-retest reliability: ICC (3, 1)=.90 (FABQ for physical activity) and .97 (FABQ for work) these values were statistically significant (p<.01). The Cronbach's alpha value for FABQ was .90 (p<.01). FABQ moderately correlated with pain, disability, anxiety, and depression (p<.01). The results of this study indicate that the Korean version of the FABQ is a reliable and valid instrument for measuring fear-avoidance beliefs in Korean patients with low back pain.

Pressing demands of economic competitiveness, the need for large-scale deployment, minimizing the need of human intervention, and experience from the past events and incidents at operating reactors have guided the evolution and innovations in reactor technologies. Indian innovative reactor 'AHWR' is a pressure-tube type natural circulation based boiling water reactor that is designed to meet such requirements, which essentially reflect the needs of next generation reactors. The reactor employs various passive features to prevent and mitigate accidental conditions, like a slightly negative void reactivity coefficient, passive poison injection to scram the reactor in event of failure of the wired shutdown systems, a large elevated pool of water as a heat sink inside the containment, passive decay heat removal based on natural circulation and passive valves, passive ECC injection, etc. It is designed to meet the fundamental safety requirements of safe shutdown, safe decay heat removal and confinement of activity with no impact in public domain, and hence, no need for emergency planning under all conceivable scenarios. This paper examines the role of the various passive safety systems in prevention and mitigation of severe plant conditions that may arise in event of multiple failures. For the purpose of demonstration of the effectiveness of its passive features, postulated scenarios on the lines of three major severe accidents in the history of nuclear power reactors are considered, namely; the Three Mile Island (TMI), Chernobyl and Fukushima accidents. Severe plant conditions along the lines of these scenarios are postulated to the extent conceivable in the reactor under consideration and analyzed using best estimate system thermal-hydraulics code RELAP5/Mod3.2. It is found that the various passive systems incorporated enable the reactor to tolerate the postulated accident conditions without causing severe plant conditions and core degradation.

Recombinant interferon alpha-2a is an active formula for the treatment of various cancer cells like malignant melanoma and a variety of virus infection diseases like acute or chronic hepatitis. The bioassay system based on the measurement of virus inhibitory activity by interferon has been used for interferon analysis with low repeatability. Here, we developed the HPLC assay to measure reproducibly interferon alpha-2a protein content which is replaceable to the reported bioassay. This method separated interferon alpha-2a from its oxidized forms and human serum albumin used as excipients. The regression coefficient using interferon alpha-2a EP CRS is more than 0.9 in the range from 5 ${\mu}g/ml$ to 200 ${\mu}g/ml$. The recovery result in the range from 15 ${\mu}g/ml$ to 60 ${\mu}g/ml$ is $97{\sim}104%$ and the precision is $0.2{\sim}1.7%$. The interferon alpha contents of 5 products are about 30 ${\mu}g/ml$.
