  • This study was carried out to measure the amount of daily intake on three synthetic food red colors (Amaranth: R2, Erythrosine: R3, Allura Red: R40) in foods by Korean. Analysis of three synthetic food red colors was conducted by HPLC with the foods including bread, confection, candy, alcoholic beverage, soft drink, ice cream, chocolate, and chewing gum. Recovery rates from the known concentrations of three standard food red colors which were spiked into foods were ranged from 85.1 to 100.4 (%) for each foods. Total Estimated Daily Intake (∑EDI) was from 0 to 1.632 mg/kg bw/day for each food item and from 0.512 to 7.281 mg/person/day for ages (1∼over 65 years old). The data of average food intake for each food item per person per day were obtained from the report of Korean National Nutrition Survey conducted by the Korea Ministry of Health and Welfare in 2001. Total EDI of each red colors per person per day were showed as follows; 0.742 mg/kg bw/day for R2, 0.391 mg/kg bw/day for R3 and 2.018 mg/kg bw/day for R40 as total amount respectively, and the ranges of these values were 0.5∼7.1% of FAO/WHO's Acceptable Daily Intake (ADI) values. Therefore, the amount of daily intake of three synthetic food red colors in Korea was regarded as safe.

  • Limited information is available on the acceptability of Korean MRLs(maximum residue limits) and the health risk based on the pesticide exposure by food intake. The aim of this study was to evaluate TMDI(theoretical maximum daily intake) and EDI(estimated daily intake) for Korean by using MRLs, food intake, residue data, and correction factors, and compare with ADI(acceptable daily intake) in order to estimate the health risk based on the pesticide exposure. The study was performed in three steps. In the frist step, the residual pesticides in each category of food were investigated using the pesticide residue analytical data(1995-96) from officially approved organizations and the analytical data for poultry was adopted from Korean food code method. In the second step, TMDI was estimated from MRLs and food factors, and was compared with ADI. In the third step, the effectiveness of each culinary treatment (washing, peeling, steaming, boiling, and salting) was evaluated and EDI was calculated using pesticide residue data, food factor, and correction factor by treatment. TMDI obtained from MRLs and food intake, and food intake was summed as 1,100.99 g, which was 79.1% of total consumption. The percent ratio of TMDI to ADI for 156 pesticides was mostly below 80% and only 30 pesticides exceeded the ADI. In particular, non-treated EDI from pesticide residue data and food intake was summed up to about 43 $\mu\textrm{g}$/day/capita, and the rank was procymidone(8.6 $\mu\textrm{g}$) > maleic hydrazide(8.2 $\mu\textrm{g}$) > EPN(3.7 $\mu\textrm{g}$) > deltamethrin(3.5 $\mu\textrm{g}$) > cypermethrin(3.0 $\mu\textrm{g}$). The treated EDI calculated from pesticide residue data, food intake, and correction factor by culinary treatment was summed up to 13.7 $\mu\textrm{g}$/day/captia. The percentage of ADI was TMDI(79.74%) > non-treated EDI (0.17%) > treated EDI (0.04%), and the exposure level of Korean population to whole pesticides was below the level to produce health risk. Oncogenic risk of five pesticides used in Korea whose oncogenic potency(Q*) was known were assessed from TMDI and treated EDI. Dietary oncogenic risk for Korean was estimated to be 2.0$\times$10-3 on the basis of TMDI, 8.3$\times$10-7 on the basis of treated EDI. The oncogenic risk from TMDI exceeded the risk level(1$\times$10-6) of EPA, whereas the oncogenic risk from treated EDI and real exposure level lower than that of EPA.

  • This study has been carried out to estimate mean concentration and the daily intake of 2 artificial sweeteners (aspartame and sucralose) by analyzing food samples. Total number of samples was 755 and the number of samples detected for sweeteners was 33 (detection rate was 4.4%). Contribution rate to total estimated daily intake (%) of artificial sweeteners in food categories was high in candy for aspartame and sucralose. Total Estimated Daily Intakes $({\Sigma}EDI)$ for different age groups were high in $13{\sim}19$ years old for aspartame and $7{\sim}12$ years old for sucralose. Total estimated daily intakes $({\Sigma}EDI)$ of men and women were 5.10 mg/person/day and 4.88 mg/person/day, respectively. Total estimated daily intakes $({\Sigma}EDI)$ of artificial sweeteners were shown as follows; 3.75 mg/person/day for aspartame and 1.27 mg/person/day for sucralose, respectively and assuming a body weight of 55 kg. These values were ranged from $0.15{\sim}0.17%$ of acceptable daily intake (ADI) evaluated by FAO/WHO and $1.0{\sim}21.4%$ of theoretical maximum daily intake (TMDI), and therefore, judged to be safe.

  • This study is to evaluate the drought-related bigdata characteristics published from South Korean by developing crawler. The 5 years (2013 ~ 2017) drought-related posted articles were collected from Korean internet search engine 'NAVER' which contains 13 main and 81 local daily newspapers. During the 5 years period, total 40,219 news articles including 'drought' word were found using crawler. To filter the homonyms liken drought to soccer goal drought in sports, money drought economics, and policy drought in politics often used in South Korea, the quality control was processed and 47.8 % articles were filtered. After, the 20,999 (52.2 %) drought news articles of this study were classified into four categories of water deficit (WD), water security and support (WSS), economic damage and impact (EDI), and environmental and sanitation impact (ESI) with 27, 15, 13, and 18 drought-related keywords in each category. The WD, WSS, EDI, and ESI occupied 41.4 %, 34.5 %, 14.8 %, and 9.3 % respectively. The drought articles were mostly posted in June 2015 and June 2017 with 22.7 % (15,097) and 15.9 % (10,619) respectively. The drought news articles were spatiotemporally compared with SPI (Standardized Precipitation Index) and RDI (Reservoir Drought Index) were calculated. They were classified into administration boundaries of 8 main cities and 9 provinces in South Korea because the drought response works based on local government unit. The space-time clustering between news articles (WD, WSS, EDI, and ESI) and indices (SPI and RDI) were tried how much they have correlation each other. The spatiotemporal clusters detection was applied using SaTScan software (Kulldorff, 2015). The retrospective and prospective cluster analyses were conducted for past and present time to understand how much they are intensive in clusters. The news articles of WD, WSS and EDI had strong clusters in provinces, and ESI in cities.

  • Recently, RFID(Radio Frequency Identification) application technology is the core of ubiquitous technology. this research examines the factors for adopting the RFID application technology together with factors for adopting the related information system such as ERP, SCM, EDI by researching relevant literature. this research attempts to derive the factors for adopting RFID application technology by using the Delphi Method. The factors for adopting the information technology of the above-mentioned three areas totaled 116 adoption factors. Based on these 116 adoption factors, the factors for adopting RFID application technology were to be derived. A total of 27 adoption factors were derived in the first Delphi investigation. Of the total 27 adoption factors, final 9 adoption factors could be derived by conducting frequency analysis and relative importance analysis. In other words, 9 adoption factors that were derived last were found to be the cost related to tag, relationship with customer firms, compatibility of technology, information technology-based structure, trust and coordination between business firms, intensity of competition within the industry, the standardization of RFID technology, the top management's support and participation degree of client companies. When business firms try to adopt RFID application technology afterwards, concrete and close examination from this point of view was found to be necessary.

  • In Korean, nine tar colors are permitted in foods. This study assessed these compounds in the favorite food items of children found near elementary schools. A total of 439 items categorized under six food types were included in the analysis. The most frequently detected tar colors were tartrazine (Y4), Brilliant Blue FCF (Y5), Allura Red, and Sunset Yellow FCF, respectively. One or a mixture of two tar colors were commonly found in products such as gums, ice bars, soft drinks, and cereals. However, most often, combinations of two or three tar colors were detected. The levels of tar colors in candies, chocolates, gums, ice bars, cereals, and soft drinks were 0.11-1169.58 mg/kg, 0.73-468.02 mg/kg, 0.10-602.46 mg/kg, 0.25-162.32 mg/kg, 0.11-753.68 mg/kg, and 0.21-69.45 mg/kg, respectively. Tar color levels were higher in chocolates and gums than in soft drinks and ice bars. And Y4 and Y5 were detected at the highest levels. For ages 7-12, the total estimated daily intake (${\sum}EDI$) of each tar color ranged from 0.004 to 1.017 mg/day/person. These values were 0.02-5.98% of the FAO/WHO's acceptable daily intake (ADI).

  • The purpose of this study is the establishment of scientific processes for making food safety policies. Thus, we investigated pesticide residue level of the agricultural commodities from market, and performed risk assessment. Fifteen agricultural items are chosen based on the frequency of Korean consumption. The samples were collected from 9 cities where populations are more than one million. Total 283 active ingredients were monitoring ( total sample number =232). Single-analysis of target pesticides was for three kinds of possible growth regulators and the multicomponent analysis was for 280 kinds of pesticides, a total of 283 species were selected to perform the pesticide residues. Before monitoring the analytes, the improvements of the analytical methods were done by method validations under the CODEX analytical method development guidelines and can produce metrics that represent the international standards applied in accordance with the guidelines. In addition to residual pesticides detected during monitoring we compare the ADI to EDI values using detected result and dietary consumption data which is extracted from annual market basket survey. The 163 samples were non-detected in the total 232 samples so it means that every agricultural commodity will residual pesticides-free in 70.3%. The detected residual pesticides showed for a total of 69 cases (29.7%). Two of samples violate Korean MRL (0.9%). The ratio of EDI compared to ADI resulted in only from 0.00087 to 0.902%. In result, we can assume that all detected residual pesticides are very safe level and current policies of Korean pesticides control may be working.

  • This study evaluated the potential human health risk on the basis of the level of bioaccumulation and EDI (Estimated Daily Intake) of microcystin-LR, one of hepatotoxic, in organs, including liver, muscle, viscera and gill, of fish from Lake Yeongeheon and Lake Daecheong when the cyanobacterial water-blooms broke out. The result has confirmed that Carassius cuvieri from Lake Yeongcheon contains higher level of microcystin-LR in its organs including liver. In Lake Daecheong, omnivorous Hemibarbus labeo and phytoplanktivorous Carassius cuvieri have shown high microcystin-LR level on average, especially higher for viscera, and Carassius cuvieri has appeared to contain higher level of microcystin-LR in the liver and the gill compared with other species. As a result of comparison between EDI of microcystin-LR from each organs and TDI (Tolerable Daily Intake) of WHO (Chorus and Bartram, 1999) to evaluate human health risk, the EDI levels from Carassius cuvieri's organs except museles have exceeded TDI level at the both lakes. Consequently, the study has proved that microcystin was bioaccumulated in the various parts of fish, and it can be ingested by human resulting in risking human health. Continuous monitoring and reducing consumption of fish, especially Carassius cuvieri, during the cyanobacterial water-blooming period will be needed to protect human health.
