  • Background: Fish and fishery products (FFPs) unintentionally contaminated with various environmental pollutants are major exposure pathways for humans. To protect human health from the consumption of contaminated FFPs, it is essential to develop a systematic tool for evaluating exposure and risks. Objectives: To regularly, accurately, and quickly evaluate adverse health outcomes due to FFPs contamination, we developed an automated dietary exposure and risk assessment system called HERA (the Human Exposure and Risk Assessment system for chemicals in FFPs). The aim of this study was to develop an overall architecture design and demonstrate the major features of the HERA system. Methods: For the HERA system, the architecture framework consisted of multi-layer stacks from infrastructure to fish exposure and risk assessment layers. To compile different contamination levels and types of seafood consumption datasets, the data models were designed for the classification codes of FFP items, contaminants, and health-based guidance values (HBGVs). A systematic data pipeline for summarizing exposure factors was constructed through down-scaling and preprocessing the 24-hour dietary recalls raw dataset from the Korea National Health and Nutrition Examination Survey (KNAHES). Results: According to the designed data models for the classification codes, we standardized 167 seafood items and 2,741 contaminants. Subsequently, we implemented two major functional workflows: 1) preparation and 2) main process. The HERA system was developed to enable risk assessors to accumulate the concentration databases sustainably and estimate exposure levels for several populations linked to seafood consumption data in KNAHES in a user-friendly manner and in a local PC environment. Conclusions: The HERA system will support policy-makers in making risk management decisions based on a nation-wide risk assessment for FFPs.

  • Elder people in Korea was affecting the nutritional status by following factors : low energy intakes, low food diversity, and poor quality of nutrition. Management a nutrition education program was planned to change the elder's nutrition knowledge and improve their nutritional status. There are seven kinds of indicator - knowledge for health questionnaire (before and after education) - we have investigated elderly nutrition education group in Su-Jung ku, Sung-Nam city. The items of surveyed was general characteristics and anthropometric measurement of the elder people, their mini dietary assessment index score, nutritional risk, nutrition knowledge test, and it's valuation comparisons between the before and after every education we did. According to the results of mini dietary assessment index score, the mean was 22.7 at the maximum 30 points and $94.2\%$ of respondents got more than nomal group. The nutritional risk score was the highest in 'high risk' group. Also the results of nutrition knowlede test showed that the mean increase $35.1\%$ of respondents. Therefore, significant improvement results showed by nutrition education programs in elders. These results suggests that the educating nutrition programs fur elder's encouraging eating behavior themselves and changing their knowledge in nutrition.

  • Objectives: This study was performed to verify the validity and judgment criteria setting of a health status assessment tool based on dietary patterns for middle-aged women. Methods: A total of 474 middle-aged women who visited the Comprehensive Medical Examination Center at Hanmaeum Hospital in Changwon were enrolled (IRB 2013-0005). The validity was verified using clinical indicators for the diagnosis of metabolic syndrome (MS), and it was used to set the criteria for the tool. A logistic regression analysis was performed for validation. The area under-receiver operation (AUC), sensitivity, specificity, and Youden Index were calculated through ROC curve analysis. Statistical analysis was performed by SPSS 21, and p value <0.05 was considered to be statistically significant. Results: The mean score of the group with no MS (73.3 points) was significantly higher compared to the group with MS (65.7 points) (p<0.001). An analysis of the association between the tool scores and risk of MS showed a 0.15-fold reduction in the risk of MS every time the tool's score increased by one point. As the result of the ROC curve analysis, the assessment reference point was set to 71 points, indicating 77.0% sensitivity and 61.0% specificity. Risk of MS was significantly higher in the group with a score of less than 71.0 than a group with more than 71 points (OR=5.28, p<0.001). Conclusions: This study was the first attempt to develop a health status assessment tool based on the dietary patterns for middle-aged women, and this tool has proven its usefulness as an MS assessment tool through the application of middle-aged women in the field of health screening.

  • It is very important to screen the elderly for nutritional risk, because nutritional status is a critical factor to maintain their health. Some nutrition checklists used in Korea for the elderly are from other countries. Reliability of those checklist in Korea is not studied enough. This survey was done for the elderly over 65-years-old who live in Hong-cheon, An-dong, Dam-yang and Yeon-gi in Korea (subject; summer: 146, winter: 145) to study the reliability of DETERMINE checklist which is adopted widely in Korea. Using the score of DETERMINE checklist, the elderly were divided as high, middle and low risk groups. For nutritional assessment for those elderly, dietary assessment using 24 recall, anthropometry, biochemical assessment and health condition were used. Results for the checklist showed that percentage below EAR for energy intake and protein intake in winter were higher in the high risk group than other groups. The intakes of phosphorus and iron and most vitamins were below the DRI. The percentage of subjects with intake below DRI was highest in the high risk group. Sensitivity, specificity, and positive predictive values using the DETERMINE were calculated using 6 point as a cut-off point. Subjects were divided into two groups by MAR (MAR < 0.75:undernutrition, MAR < 0.75 : normal). Sensitivity recorded 49.4% and 34.3%, specificity did 61.9% and 65.4 and Positive predictive value did 62.1% and 46.0% each for summer and winter. Results of screening using DETERMINE Checklist were not matched with dietary assessment but not with anthropometric and biochemical measurement. In conclusion DETERMINE 'Checklist' is shown be a good screening tool for finding out risk groups for dietary intake in the elderly, It needs to verify reliability and validity through large-scale survey.

  • Residue monitoring of propiconazole (PCZ) in cabbage, shallot, and spinach was conducted under multi-trial greenhouse conditions. This study aimed to understand the fate of the applied fungicide in these vegetables. Furthermore, the associated health risk of PCZ in leafy vegetables was assessed through dietary risk assessment. Commercially available PCZ (22% suspension concentrate) was administered thrice according to the OECD fungicide application interval guideline. The plant samples were extracted using a slightly modified QuEChERS technique and analyzed using gas chromatography-tandem mass spectrometry. The average PCZ recovery was between 84.5% and 117.6%, with a <5% coefficient of variance. The dissipation of PCZ residue in cabbage, shallot, and spinach after 14 days was 96%, 90%, and 99%, respectively, with half-lives of <5 days. Meanwhile, dietary risk assessments of PCZ residues in the studied vegetables using the risk quotient (RQ) were significant < 100 (RQ < 100). Thus, the population groups considered in this study were not at substantial risk from consuming leafy vegetables sprayed with PCZ following critical, good agricultural practices.

  • The influence of nutrition during early life on physical growth as well as mental development has been thoroughly discussed in the literature. The physical dimensions of the body are greatly influenced by nutrition, particularly during the period of rapid growth in early childhood. Nutritional status affects every pediatric patient's response toillness. Good nutrition is important for achieving normal growth and development. It is indicated that permanent impairment of the central nervous system may result from dietary restriction of imbalance during certain periods of life. If children under 3 years of age show a good nutritional status, it may be assumed that they are well nourished. Several common diseases of children such as iron deficiency, chronic constipation and atopic dermatitis are known food related diseases. Patients with chronic illness and those at risk of malnutrition should have detailed nutritional assessments done. Components of a complete nutritional assessment include a medical history, nutritional history including dietary intake, physical examination, anthropometrics (weight, length or stature, head circumference, midarm circumference, and triceps skinfold thickness), pubertal staging, skeletal maturity staging, and biochemical tests of nutritional status. The use of age, gender, and disease-specific growth charts is essential in assessing nutritional status and monitoring nutrition interventions. Nutrition assessment and dietary counseling is helpful for the cure of disease, and moreover, the prevention of illness.

  • With the diversification and internationalization of the food industry and the increased focus on health from a majority of consumers, food safety policies are being implemented based on scientific evidence. Risk analysis represents the most useful scientific approach for making food safety decisions. Total diet study (TDS) is often used as a risk assessment tool to evaluate exposure to hazardous elements. Many countries perform TDSs to screen for chemicals in foods and analyze exposure trends to hazardous elements. TDSs differ from traditional food monitoring in two major aspects: chemicals are analyzed in food in the form in which it will be consumed and it is cost-effective in analyzing composite samples after processing multiple ingredients together. In Korea, TDSs have been conducted to estimate dietary intakes of heavy metals, pesticides, mycotoxins, persistent organic pollutants, and processing contaminants. TDSs need to be carried out periodically to ensure food safety.
