Purpose: The purpose of the study was to evaluate the accuracy of two different fluid intake measurement methods (fluid only vs. all dietary intake) in measuring fluid balance compared to body weight change among patients with cancers. Methods: A total of 60 cancer patients in an urban cancer center in South Korea participated in the study. Adult patients who were over 18 years old; having 24-hour I&O order; and taking either normal regular diet or soft blend diet were included. Demographic information and disease related information were also gathered. The data were analyzed using SPSS 18.0 program. Results: Measuring 'fluid only' for oral intake was a more accurate measure than measuring 'all dietary intake' (p=.026 vs. p=.094). Both methods had positive correlations with the amount of weight change (r=.329, p=.010; r=.303, p=.019). Measuring body weight was a more accurate and efficient way of evaluating the fluid balance than 24 hour cumulative I&O. Conclusion: Developing clinical manual for selecting proper patients who needs fluid balance monitoring is imperative. Administering weight check and/or 24 hour cumulative I&O should be considered thoroughly based on solid nursing evidence in future.

The purpose of this survey is to investigate the nutritional status and dietary intake of gastrectomized cancer patients in Asan Medical Center. The subjects were 98 patients, who underwent a gastrectomy due to gastric cancer and were admitted to the General Surgery Department during March 2007 to December 2007. We examined general characteristics (sex, age, clinicopathological stage, type of operation), anthropometric data (height, weight change), biochemical data (red blood cell RBC, hemoglobin HGB, hematocrit HCT, mean corpuscular volume MCV, total lymphocyte count TLC, albumin, total cholesterol), dietary intake and dietary intake related symptoms. Weight loss of gastrectomized patients was $9.0{\pm}4.3$% from preillness weight to visiting out-patient department (OPD) weight. Biochemical data (RBC, HGB, HCT, MCV, TLC, albumin, total cholesterol) significantly deteriorated after gastrectomy. However, outpatient visits were all restored to the normal range. Postoperative energy intake was $785.0{\pm}164.2$ kcal, which corresponds to $41.6{\pm}9.6$% of daily energy requirement. The cause of poor oral intake is mostly fear, abdominal pain and abdominal discomfort. Therefore, to control pre-or post-operative weight change in the future requires, focusing on the body weight to maintain a normal or usual nutrition by interventions and increased caloric intake during hospitalization for the development of nutrient-dense meals. In addition, as the main reason of the lack of intake of meals after the gastrectomy was fear, the patients should be actively encouraged to consider the importance of eating proper meals.

Background: In South Korea, as an aged society, an understanding of dementia and its risk factors is important from clinical and healthcare policy perspectives. Relationship between cognitive impairment and body weight or weight changes have been reported, but these were contradictory. We have evaluated the association between weight changes and cognitive decline using national level longitudinal data. Methods: Data from the Korean Longitudinal Study of Ageing from 2006 to 2012 were used. Association between weight changes and decline in cognitive function as measured by K-MMSE (the Korean version of the Mini-mental state examination) score was assessed by multivariate logistic regression. Weight changes were calculated from 1st wave and 3rd wave survey data, and classified into five groups as stable, increases, decreases of >10%, or 5%-10%. Results: About 37% of the total participants (n=4,512) were 65 years or older. These participants made up the largest proportion of the groups with weight change exceeding 10%. Multivariate logistic regression analyses revealed that weight changes exceeding 10% (10% increase vs stable, adjusted OR [aOR] 1.47, 95% confidence interval (CI) 1.11-1.95; 10% decrease vs stable, aOR 1.44, 95% CI 1.11-1.88) were significant predictive factors for decline in cognitive function. In subgroup analyses, the association between weight changes and cognitive decline was significant in males aged over 65 years and in normal BMI groups. Conclusion: Weight changes, both increases and decreases exceeding 10% of baseline, were significantly associated with declines in cognitive function among older adults in South Korea.

This study was performed to evaluate the effects of Quibitang in the chronic mild stress(CMS) model of depression in rats. Chronic exposure to mild unpredictable stress was found to depress the consumption of sucrose solution in rats for 8 weeks. These CMS-treated rats were stratified into Quibitang gruop and saline group. And control rats were also stratified into Quibitang group and saline group. The change of the consumption of sucrose solution and the body weight were measured, and open field test, elevated startle response and plus maze test were performed, to investigate the anti-depression effect of Quibitang. The results were as follows: 1. The consumption of sucrose solution was significantly reversed in Quibitang-treated group at 9th, 11th, 12th week, but there was no significant change at 10th week 2. CMS schedule decreased body weight. CMS-treated groups showed decrease of body weight after 5 weeks. After 10 weeks, Quibitang group showed lower body weight than saline group in CMS-treated groups 3. In open field test, Quibitang group showed significant difference of locomotion, latency. 4. In elevated startIe test, Quibitang group showed no significant change of startle response. 5. In plus maze test, Quibitang group showed no significant change of plus maze-time and plus maze-error.

Radar remote sensing is appropriate for rice monitoring because the areas where this crop is cultivated are often cloudy and rainy. Especially, Synthetic Aperture Radar (SAR) can acquire remote sensing information with a high temporal resolution in tropical and subtropical regions due to its all-weather capability. This paper analyzes the relationships between backscattering coefficients of rice measured by RADARSAT-2 SAR and growth parameters during a rice growth period. And we applied the relationships to crop monitoring of paddy rice in North Korea. As a result, plant height and Leaf Area Index (LAI) increased until Day Of Year (DOY) 234 and then decreased, while fresh weight and dry weight increased until DOY 253. Correlation coefficients revealed that Horizontal transmit and Horizontal receive polarization (HH)-polarization backscattering coefficients were correlated highly with plant height (r=0.95), fresh weight (r=0.92), vegetation water content (r=0.91), LAI (r=0.90), and dry weight (r=0.89). Based on the observed relationships between backscattering coefficients and variables of cultivation, prediction equations were developed using the HH-polarization backscattering coefficients. Concerning the evaluation for the applicability of the LAI distribution from RADARSAT-2, the LAI statistic was evaluated in comparison with LAI distribution from RapidEye image. And LAI distributions in Pyongyang were presented to show spatial variability for unaccessible areas.

This study was done to investigate whether dietary fats differing in their fatty acid compositions change hepatic mitochondrial lipid composition and thereby change adenine nucleotide translocase activity. Male Sprague-Dawley rats were fed 5 different wxperimental diets for 6 weeks, which were different in their fatty acid compositions. The dietary fats were beef tallow(BT), olive oil(OO), corn oil(CO), perilla oil(PO) and sardine oil(SO) as a source of saturated fatty acid, oleic acid, n-6 linoleic acid, n-3 $\alpha$-linolenic acid and n-3 eiocosapentaenoic acid+docosahexaenoic acid respectively. Body weight of PO group was significantly higher than that of either BT or SO group. This increase in body weight of PO group was due to the increase of food intake. Although there was no difference in liver weight, % liver weight per body weight of SO group was significantly higher than BT and OO groups. Analysis of mitochondrial lipid composition showed that dietary oils differing their fatty acid compositions altered mitochondrial fatty acid patterns, especially n-6/n-3 ratio, cholesterol/phospholipid ratio and phopsholipid composition. The n-6/n-3 ratio was highest in CO group but lowest in SO group whereas the ratio of Chol/PL was highest in SO group but lowest in CO group. Such changes in mitochondrial lipids did not lead to a significant alteration in the activities of adenine nucleotide translocase, which is embedded in mitochodrial inner membrane.

Purpose: The purpose of this study was to examine test-retest reliability and criterion-related validity of a trunk stability robot when measuring the weight-bearing symmetry static sitting and standing in stroke patients. Methods: For 27 stroke patients, weight-bearing symmetry was assessed twice, 7 days apart. The intraclass correlation coefficient (ICC2,1) and minimal detectable change (MDC) were used to examine the level of agreement between test and retest. The criterion-related validity of weight -bearing symmetry was demonstrated by Spearman correlation of modified Barthel index (MBI), the sit to stand test (STS), the timed up & go Test (TUG), and the function in sitting test (FIST). Results: the test-retest agreements were excellent for the weight-bearing symmetry of static sitting (ICC2,1: 0.90) and standing (ICC2,1: 0.89). It all showed that the acceptable MDC for the weight-bearing symmetry of static sitting and standing was 0.11 and 0.16, respectively (highest possible score<20 %), indicating that the measures had a small and acceptable degree of measurement error. The weight-bearing symmetry of static sitting was significantly correlated with the TUG(r=-0.45) and FIST(r=0.46)(p<0.05); the weight-bearing symmetry of static standing was also significantly correlated with MBI (r=0.65), TUG (r=-0.67), FIST (r=0.61)(p<0.01), and STS (r=-0.47)(p<0.05). Conclusion: The weight-bearing symmetry of static sitting and standing assessed by the trunk stability robot showed highly sufficient test-retest agreement and mild-to-moderate validity. It could also be useful for clinicians and researchers to evaluate balance performance and monitor functional change in stroke patients.
