Purpose: The purpose of this study was to investigate the nutritional support, gastric residual volume, and nutritional status of the intensive care unit (ICU) patients on enteral feeding. Methods: A descriptive longitudinal design was used to collect 5 day data on enteral nutrition of 52 ICU patients in an university hospital. Nutritional support was calculated with actual caloric intake compared to individual caloric requirement. Residual volumes were measured prior to routine feedings, and the serum albumin levels and the total lymphocyte counts were checked to evaluate nutritional status. The data were analyzed using one group repeated measures ANOVA, paired t-test, and Spearman's bivariate correlation analysis. Results: The subjects received their first enteral feeding on the $5.75^{th}$ day of ICU admission. The mean nutritional support rate was 49.1% of the requirement, however prescription rate and support rate were increased as time goes by. Gastric residual volumes were less than 10 cc in 95% cases. A significant negative correlation was found between nutritional support and nutritional status. Conclusion: The nutritional support for ICU patient was low compared to the requirement, and their nutritional status was worse than at the time of ICU admission. Further studies are necessary to develop nursing interventions for improving nutritional support for ICU patients.

Purpose: The purpose of this study was to evaluate preoperative nutritional status in elderly patients with orthopedic surgery and identify related factors for malnutrition risk. Methods: This study enrolled 337 patient's medical record who underwent orthopedic surgery in hospital between January and December 2015. Data was collected retrospectively. Nutritional status was evaluated by using the Nutritional Risk Screening 2002. Multivariable logistic regression analysis was used to identify independent related factors for malnutrition risk. Results: Malnutrition risk developed in 58 patients (17.2%). Logistic regression analysis identified low physical activity, visual impairment, depression, sleep disorder, low serum calcium level, and low serum albumin level as related factors. Conclusion: Orthopedic surgery in elderly patients was associated with high risk of preoperative malnutrition. The results of this study suggest that evaluating the nutritional status and related factors should be done with preoperative status of elderly patients. At the same time, interventions for nutritional care should be adjusted to meet the nutritional needs of individuals and decrease the risk of malnutrition.

In the assessment of the biosafety of genetically modified (GM) crops, a comparative approach to identifying similarities and differences between transgenic and non-transgenic crops is helpful in identifying potential safety and nutritional issues. In this study, we aimed to compare the nutritional composition of a protopanaxadiol-enhanced genetically modified rice (PPD GM rice) with its non-transgenic counterpart. The nutritional profile of PPD GM rice was assessed against that of the parental rice cultivar 'Dongjin' to ascertain nutritional equivalence. No differences were observed between PPD GM and Non-GM rice cultivar in proximate analysis, mineral content, and amino acid composition. Although significant differences were observed in crude fat, crude protein, total dietary fiber, and some minerals between PPD GM rice and Dongjin, these variances fell within the range suggested by common cultivars (Anmi and Nipponbare) and Organization for Economic Cooperation and Development (OECD) data. Similarly, while some amino acids showed significant differences, these metabolites did not deviate from the OECD range. Principal component analysis (PCA) was conducted using the nutritional analysis data of PPD GM rice and Dongjin. The results revealed that PPD GM rice and Dongjin were grouped according to their respective cultivation years. This suggests that the variability in the nutritional composition of PPD GM rice tends to resemble that of the parental rice cultivar 'Dongjin' rather than being solely attributed to genetic modification. Overall, our findings indicate that the nutritional composition of PPD GM rice is substantially equivalent to that of its non-transgenic counterpart.

Objectives: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. Methods: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. Results: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. Conclusions: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.

Purpose: The purpose of this study was to evaluate the nutritional status of elderly Korean women and to investigate related factors. Methods: A total of 100 elderly women attending a local elderly welfare center were recruited for study. Evaluation criteria included demographics, clinical status, nutritional status (using a mini-nutritional assessment), food intake, and nutritional bioparameters, including homocysteine, transferrin, prealbumin and lymphocyte levels, and their antioxidant power status. Results: Among the test group, 83% of the subjects were classified as undernourished, and they often had hyperlipidemia and a lower intake of fiber ($p$ <.05, respectively) and vegetables than normal subjects. In a correlation analysis, their nutritional status was associated with abdominal circumference, the Korean Geriatric Depression Scale score and the Enriched Social Support Inventory score. Nutritional bioparameters and antioxidant power were associated with age among undernourished subjects. Old age, the prevalence of hyperlipidemia, and poor social support significantly increased the risk of undernutrition. Poor social support, the prevalence of diabetes mellitus and depression significantly increased the risk of nutritional deficiency after controlling for age, educational and economic variables. Conclusion: More strategies to increase social support in the Korean female elderly population may improve their nutritional status.

Purpose: The aim of this study was to evaluate the quality characteristics of rice nutritional bars prepared by adding Chinese artichoke (CA) powder to the rice powder. Methods: CA rice nutritional bars were prepared with various levels of CA powder (0%, 5%, 10%, 15%, and 20%) and designated as CA0 (without CA powder), CA5, CA10, CA15, and CA20, respectively. The total phenolic content, DPPH free radical scavenging activity, moisture content, pH, baking loss rate, leavening rate, volume, color, texture analysis, and sensory evaluations of rice nutritional bars were performed. Results: The total phenolic content and DPPH free radical scavenging activity exhibited an increase with increase in the substitute amount of CA powder. The results showed that the pH of rice nutritional bars decreased in all sample groups as the content of CA powder increased. The volume of the sample group with CA powder was higher than that of CA0. As the content of CA powder increased, lightness of the rice nutritional bars crumbs decreased while redness and yellowness increased. The texture analysis of rice nutritional bars showed that hardness, gumminess, and chewiness were the highest in CA0 while springiness and cohesiveness were the lowest in CA0. With respect to characteristic intensity rating, the taste, flavor, and softness of rice nutritional bars increased with increasing amounts of CA powder. In terms of consumer acceptability, CA15 and CA20 received the highest scores with respect to texture. Conclusion: Therefore, the results of this study indicate that replacing 15% of the rice powder with CA led to an efficient enhancement in the antioxidant and nutritional values of rice nutritional bars as well as the sensory quality.

This study deals with the conditions of nutritional intake of the urban elderly (age sixty years and older). This study analysis is based on factors that are influenced on the prevalent conditions of dietary-intake of the urban elderly either it be for better ment of health or desire. The method of this research was based on the interview-survey with questinaire in the Seoul area. In comparison to the surveys taken of the rural society and the urban slum elderly the urban elderly standard nutritional requirements was higher. Of the standard nutritional requrieemtns the twomen's nutrition intake was higher than of the men. But still the problem of malnutrition existed in the urban elderly both men and women at the probability nutritional deficienty rate higher than 30%. The food intake frequency factors which might influence the condition of nutritional intake was significant more than condition of eating. Another important factors of the conditions of nutritioal intake of the urban elderly are one's self-consciousness of health and degree of one's will change . In healthy case of the aged, their will was almost maintained and hand -grip strength was high when they had regular meal with their family . For elderl with the lower academic career and the one with more satisfactory to his meal, their wills didn't change before or after retirement. The objectiveness of this survey is to convince the elderly that the problems of nutritional deficiency can only be solved by reeducation and to improve their nutritional diet to have the enjoyments of a healtheir elderly life.

Our study aims to assess life satisfaction and evaluate its relationship with depression, nutritional status and cognitive function among the elderly. This study is a pathway analysis study using 9089 elderly people and was conducted as a supplemental analysis using the data from the 2017 Korean Elderly Examination Survey. As a result, depression, nutritional status, cognitive function and life satisfaction showed significant correlation. Nutritional status(.46, p=.007), and cognitive function(-.27, p=.014) were directly affected by depression. Both nutritional status(.08, p=.009) and cognitive function(-.03, p=.010) had effect on life satisfaction but life satisfaction was mediated by nutritional status and cognitive function in affecting to life satisfaction. It suggests that nursing intervention is needed for nutritional status and cognitive function for life satisfaction of the elderly.
