본 실험에서는 성장기용 조제식에 함유된 유지를 대상으로 전위차 적정법 및 뷰렛 적정법에 의한 과산화물가를 측정하고 그 측정불확도를 비교하여 산정하였다. GUM(Guide to the expression of uncertainty in measurement) 및 Draft EURACHEM/CITAC Guide의 이론에 기초하여 측정불확도를 구하였으며, 불확도 인자로서 적정액의 농도, 시료량 및 적정량 등이 작용하였다. 뷰렛적정에 의한 과산화물가 측정값과 확장불확도는 $2.05{\pm}0.17\;meq/kg$ 으로 표현되었으며, 전위차적정에 의한 경우는 $1.96{\pm}0.07\;meq/kg$ 으로 표현되었다. 적정과정에서의 측정불확도가 전체불확도의 대부분을 차지하였으며, 전위차적정법에 의한 측정불확도는 뷰렛적정법에 의한 경우보다 낮게 나타나 과산화물가가 낮은 시료의 측정시에 바람직한 측정방법으로 사료되었다.

The most critical point in the assessment of adherence to dietary guidelines is the development of a practical definition for adherence, such as a dietary pattern score. The purpose of this study was to develop the Korean Diet Score (KDS) based on the Korean Food Balance Wheel and to examine the association of KDS with various lifestyle characteristics and biochemical factors. The dietary data of 5,320 subjects from the 4th Korean National Health and Nutritional Examination Survey were used for the final analysis. The food guide was composed of six food group categories; 'grain dishes', 'fish and meat dishes', 'vegetable dishes', 'fruits', 'milk' and 'oils and sugars'. Based on the recommended serving numbers for each group, the scores measuring adherence to this food guide were calculated from the dietary information from the 24-hour dietary recall questionnaire, and then its correlation with various characteristics was assessed. KDS was significantly associated with several clinical, lifestyle and socioeconomic factors as well as diagnosed disease history. The higher quintile group of KDS showed a significantly lower level in fasting blood glucose, systolic blood pressure, triglycerides, current smoking and drinking as well as higher leisure time activity, house income and education. Furthermore, the KDS quintile group of women was inversely associated with hypertension, osteoporosis and diabetes. A higher KDS quintile was characterized with a higher intake of several critical nutrients, such as Ca, Fe and vitamins as well as a desirable nutrition balance such as the ratio of macronutrients. Our results demonstrate that KDS is a beneficial tool in assessing the adherence to a healthy diet based on the Korean dietary guidelines. We suggest that KDS could be a useful indicator for evaluating the dietary balance of the Korean population.

An investigation was conducted to evaluate the hygienic status of 33 high school foodservice systems in Yongin city by using hygiene management guide checklist, ATP bioluminescence assay and microbe inspection petrifilm (APC, coliform group, Staphylococcus aureus) of food utensils during use. The 22 hygiene management guide checklist items about facilities, personal hygiene, food control, distribution, washing and disinfection had good grade but there were some inadequate behaviors on observation. The inspection results showed their sanitary condition met the level B of the recommendation of Korea method, it means sanitary management system get settled but more practical CCP system was needed. ATP bioluminescence assay was conducted on surface of food facilities, ATP ranged 425~2,552 RLU on gloves, 541~70,251 RLU on apron, 1,596~88,490 RLU on working desk, 1,177~263,813 RLU on sterilizer grip, 715~32,814 RLU on sterilizer shelf, 114~619,725 RLU on refrigerator grip, 677~319,007 RLU on refrigerator shelf, 71~196,725 RLU on freezer grip, 1,535~233,375 RLU on freezer shelf. APC ranged $66.7{\pm}29.0CFU$ on freezer grip, $102.1{\pm}35.9CFU$ on refrigerator grip, $45.4{\pm}28.2CFU$ on heating cabinet grip, $58.8{\pm}40.4CFU$ on sterilizer grip, the number of coliform group ranged $5.6{\pm}4.9CFU$ on freezer grip, $9.1{\pm}8.7CFU$ on refrigerator grip, $1.2{\pm}1.1CFU$ on heating cabinet grip, $4.5{\pm}4.4CFU$ on sterilizer grip. S. aureus ranged $8.0{\pm}5.6CFU$ on freezer grip, $12.2{\pm}9.6CFU$ on refrigerator grip, $2.1{\pm}1.6CFU$ on heating cabinet grip, $11.6{\pm}6.4CFU$ on sterilizer grip.

This study examines the relationships between stress and eating habits of adolescents based on the assumption that adolescents require large amounts of nutrients and that eating habits affect their physical development, academic achievement, and emotional development. For this purpose, 213 adolescents in Gangwondo, Korea, were surveyed. Many studies have reported that stress causes changes in eating habits and affects health status. Based on the dietary action guide scores according to stress categories, eating instant foods less was significant (p<0.001), eating fast foods less was significant (p<0.05), and have soft drinks less was significant (p<0.001). The results suggest the importance of balanced nutrition based on the formation of right dietary habits for adolescents. Good nutrition can be determined through right knowledge of nutrition and dietary habits, and right dietary habits can improve health and physical development as well as mental and emotional stability. The analysis did not compare other regions, and therefore any generalization of the results should be made with caution. However, the results offer important insights into stress among adolescents for their effective counseling.

The supplementation of livestock feed with animal protein is a present cause for public concern, and plant protein shortages have become increasingly prominent in China. This conflict may be resolved by fully utilizing currently available sources of plant protein. We estimated the rumen degradability and the small intestinal digestibility of the amino acids (AA) in rapeseed meal (RSM), soybean meal (SBM), sunflower seed meal (SFM) and sesame meal (SSM) using the mobile nylon bag method to determine the absorbable AA content of these protein supplements as a guide towards dietary formulations for the dairy industry. Overall, this study aimed to utilize protein supplements effectively to guide dietary formulations to increase milk yield and save plant protein resources. To this end, we studied four cows with a permanent rumen fistula and duodenal T-shape fistula in a $4{\times}4$ Latin square experimental design. The results showed that the total small intestine absorbable amino acids and small intestine absorbable essential amino acids were higher in the SBM (26.34% and 13.11% dry matter [DM], respectively) than in the SFM (13.97% and 6.89% DM, respectively). The small intestine absorbable Lys contents of the SFM, SSM, RSM and SBM were 0.86%, 0.88%, 1.43%, and 2.12% (DM basis), respectively, and the absorbable Met contents of these meals were 0.28%, 1.03%, 0.52%, and 0.47% (DM basis), respectively. Among the examined food sources, the milk protein score of the SBM (0.181) was highest followed by those of the RSM (0.136), SSM (0.108) and SFM (0.106). The absorbable amino acid contents of the protein supplements accurately reflected protein availability, which is an important indicator of the balance of feed formulation. Therefore, a database detailing the absorbable AA should be established.

Food protein-induced enterocolitis syndrome (FPIES) is an under-recognized non-IgE-mediated gastrointestinal food allergy. The diagnosis of FPIES is based on clinical history, sequential symptoms and the timing, after excluding other possible causes. It is definitively diagnosed by an oral food challenge test. Unfortunately, the diagnosis of FPIES is frequently delayed because of non-specific symptoms and insufficient definitive diagnostic biomarkers. FPIES is not well recognized by clinicians; the affected infants are often mismanaged as having viral gastroenteritis, food poisoning, sepsis, or a surgical disease. Familiarity with the clinical features of FPIES and awareness of the indexes of suspicion for FPIES are important to diagnose FPIES. Understanding the recently defined clinical terms and types of FPIES is mandatory to suspect and correctly diagnose FPIES. The aim of this review is to provide a case-driven presentation as a guide of how to recognize the clinical features of FPIES to improve diagnosis and management of patients with FPIES.
