  • Peroxide values (PV) of fat from fallow up formula were determined using redox-potentiometric titration method and standard method, which is based on KI oxidation by hydroperoxides and volumetric titration of liberated iodine, and their uncertainties were compared. Uncertainty sources in measurement, such as sample weight, sodium thiosulfate concentration, and titer, were identified and used as parameters for combined standard uncertainty based on Guide to the expression of uncertainty in measurement and Draft EURACHEM/CITAC Guide. Analytical results and combined standard uncertainties of peroxide values (PV) determined by standard burette and potentiometric titrations were $2.05{\pm}0.17\;and\;1.96{\pm}0.07\;meq/kg$, respectively, suggesting potentiometric titration method is suitable for determining PV of fat with low PV, because uncertainty of PV determination obtained by potentiometric titration was lower than that obtained by burette titration.

  • 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.

  • 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.

  • Recently, as competition in the food industry intensifies, restaurants offering unusual foods are increasing. However, the information provided by the menu is limited to the ingredients and prices of the foods, which does not help the guests choose the menu. In order to solve this problem, this paper proposes a food menu guidance system using augmented reality technology. The proposed system combines augmented reality technology and video content to provide information about food on the menu as a video. Therefore, it provides more realistic and vibrant images than the existing menu board provides food information in a simple image format. In addition, the proposed system is expected to be applied to tourist attractions, museums and galleries as a new type of guidance system beyond the limitations of text and image-oriented brochures.

  • 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.
