The purpose of this study was to estimate the effect of serving sizes on dish wastes, nutrient intake, and diet satisfaction for reduction of dish waste products. The dish waste, energy and protein intake, and satisfaction scores before and after dining were compared in 44 subjects fed various serving sizes(100%, 90%, 80% of standard size) of 10 frequently consumed Korean dishes. The result are as follows: 1. Average age, height, and weight of 44 subjects were 30.5, 174.0cm, and 68.1kg in men and 26.2, 164.2cm, and 53.5kg in women, respectively. 2. There was a significant difference in the dish waste rate of 10 Korean dishes to serving sizes. The range of dish waste rates of 10 Korean dishes was 13.14-33.04%. 3. The average energy intake from 10 Korean dishes in which 100% of the standard serving size was served was lower than Korean RDA. Protein intakes from Sulungtang, Yukgaejang, Deunjang-ggigae, and Bibimpab with 100% servins size, Soondubi-ggigae 90% servins size, and Galbitang, Bulgogi-bakpan, Sangsungui-bakpan, Bakpan 80% of standard serving size were higher than Korean RDA. 4. The satisfaction score before dining on Sulungtang, Bulgogi-bakpan, Sangsungui-bakpan decreased with decreasing serving size. However, there was no significant difference in satisfaction score after dining to serving size. These findings indicate that dish waste rate and diet satisfaction of 10 these Korean dishes are fixed and energy intake is insufficient. Therefore, for reduction of food waste and reasonable serving size of dishes evaluated in this study, there should be more studies about Korean menu development with decreasing serving size and increasing energy density.

Purpose : This study aimed to present normative data and cut-off points for older Korean adults completing the Montreal Cognitive Assessment - Korean (MoCA-K), which is used as a screening test for mild cognitive impairment in Korea. Methods : A total of 195 healthy adults ≥60 years were recruited. All participants completed the MoCA-K and the Korean - Mini-Mental State Examination (MMSE-K) to assess their cognitive function. Participants were divided into six groups based on their age: 60-64 years, 65~69 years, 70~74 years, 75~79 years, 80~84 years, and 85~89 years. Results : The results revealed that MoCA-K score decreased significantly with age (mean score ± standard deviation [SD]; 27.63±2.80 in subjects aged 60~64 years; 27.00±2.39 in subjects aged 65~69 years; 24.94±2.96 in subjects aged 70~74 years; 24.74±3.37 in subjects aged 75~79 years; 22.59±4.72 in subjects aged 80~84 years; and 18.83±5.38 in subjects aged 85~89 years; p<.001). Additionally, MoCA-K score also increased significantly with educational level (mean score±standard deviation [SD]; 19.95±4.78 in no formal education group; 24.95±2.22 in elementary school graduated group; 26.35±2.72 in middle school graduated group; 28.32±1.36 in high school graduated group; and 28.50±1.51 in more than college graduated group; p<.001). The optimal cut-off points were 24/25 for 60~69 years old group, 21/22 for 70~79 years old group, 17/18 for 80~84 years old group, and 13/14 for 85~89 years old group. The optimal cut-off points were 15/16 for individuals who were illiterate, 22/23 for individuals with 6 years of education, 22/24 for individuals with 9 years of education, and 26/27 for individuals with 12 or more years of education. Conclusions : This study presents normative data and cut-off points for the MoCA-K in older Korean adults. This data will facilitate more accurate detection and follow-up of the risk of mild cognitive impairment in this population, taking into consideration age and education. Future studies are required that should focus on the cut-off score on the level of education according to age.

This study was carried out to find the relationship between the eating disorder associated with BMI(body mass index) and nutrition knowledge by surveying 476 middle school girl students in Won Ju, Gang-Won Province, South Korea. BMI is a standard suggested for oriental people and it was differentiated into the underweight, the normal weight and the overweight. To determine the eating disorder, EAT-26(Eating Attitude Test-26) was used and in order to find out the level of nutrition knowledge DGE (Deutsche Gesellschaft fur Ernahrung) was used after some modifications and supplementations. And the results are as follows; 1) Out of the students surveyed, 22% are in underweight group, 64% are in normal weight group and just 12% are in overweight group. Except the students in underweight group, most of the surveyed students wish to lower the weight below normal weight. 2) Relationship was found between BMI and EAT-26 score that is related with eating disorder behavior, Total score was higher in overweight group than in underweight and normal weight group (P<0.001). When the score for individual question about eating disorder is considered in detail, the score for the questions preoccupied with the weight reduction was higher in overweight group than in underweight and normal weight group(P<0.001). For the questions about bulimia there was no difference according to BMI, however, for the questions about restraining food intake the score was high in overweight group(P<0.001). 3) The score of nutrition knowledge in line with BMI was different. It was found that the total score and the score for the questions about fat, calorie requirement, and calorie content in food were different. The total score showed the highest in overweight group in comparison with the ones in underweight and normal weight group. (P<0.05). Out of maccronutrient like carbohydrate, fat and protein, only the fat showed significant difference according to BMI and it was lower in overweight group than in underweight and normal weight group.(P<0.05) Out of the questions about calorie requirement, significant difference was found in the score for the questions about calorie requirement and calorie content in food. It was lower in overweight group than in underweight and normal weight group (p<0.05).

Objective : To compare the predictive power of International Classification of Diseases 10th Edition(ICD-10) based International Classification of Diseases based Injury Severity Score(ICISS) with Trauma and Injury Severity Score(TRISS) and International Classification of Diseases 9th Edition Clinical Modification(ICD-9CM) based ICISS in the injury severity measure. Methods : ICD-10 version of Survival Risk Ratios(SRRs) was derived from 47,750 trauma patients from 35 Emergency Centers for 1 year. The predictive power of TRISS, the ICD-9CM based ICISS and ICD-10 based ICISS were compared in a group of 367 severely injured patients admitted to two university hospitals. The predictive power was compared by using the measures of discrimination(disparity, sensitivity, specificity, misclassification rates, and ROC curve analysis) and calibration(Hosmer-Lemeshow goodness-of-fit statistics), all calculated by logistic regression procedure. Results : ICD-10 based ICISS showed a lower performance than TRISS and ICD-9CM based ICISS. When age and Revised Trauma Score(RTS) were incorporated into the survival probability model, however, ICD-10 based ICISS full model showed a similar predictive power compared with TRISS and ICD-9CM based ICISS full model. ICD-10 based ICISS had some disadvantages in predicting outcomes among patients with intracranial injuries. However, such weakness was largely compensated by incorporating age and RTS in the model. Conclusions : The ICISS methodology can be extended to ICD-10 horizon as a standard injury severity measure in the place of TRISS, especially when age and RTS were incorporated in the model. In patients with intracranial injuries, the predictive power of ICD-10 based ICISS was relatively low because of differences in the classifying system between ICD-10 and ICD-9CM.
