The purpose of this study was to investigate the consumption and perception on the effect of cooked rice mixed with multi-grain (CR-MG). Reason for like and dislike, intake frequency and variables related with the satisfaction of CR-MG were also investigated. The data for the analysis was collected from 315 adults who were residing at Seoul${\cdot}$Kyeonggi and Kangwon area and analyzed by the SPSS 11.0 program. The result showed that 84.8% of the respondents consumed CR-MG, showing significant difference by gender and occupation (p<0.05). It also revealed that they consumed it knowing their effect, showing significant difference by all general characteristics except for resident area and BMI, respectively. Kind of multi-grain (MG) mixed with cooked rice was high in the order of SoRiTae (80.1%) > brown rice (73.4%) > black rice (72.7%) > waxy rice (61.0%), respectively. As for the mixing type of MG, 61.4% of the respondents preferred non-mixed product rather than pre-mixed product. 2 or 3 kinds were preferred numbers of MG mixed with rice, showing significant difference by age (p<0.001) and marital status(p<0.05), respectively. 59.9% of the respondents answered 'high nutritive value more than polished rice' as the major reason for like, whereas 31.3% answered 'greatly rough more than polished rice' as that for dislike, respectively. By the use of multiple regression analysis, it revealed that health was the most significant variable which affect the satisfaction of CR-MG. From these results, it was suggested that in view of the high consumption and intention to continue the intake of CR-MG, following studies should be conducted to improve the preference of CR-MG.

This study focused on health risk assessment via multi-routes of As exposure to establish a target cleanup level (TCL) in abandoned mines. Soil, ground water, and rice samples were collected near ten abandoned mines in November 2009. The As contaminations measured in all samples were used for determining the probabilistic health risk by Monte-Carlo simulation techniques. The human exposure to As compound was attributed to ground water ingestion. Cancer risk probability (R) via ground water and rice intake exceeded the acceptable risk range of $10^{-6}{\sim}10^{-4}$ in all selected mines. In particular, the MB mine showed the higher R value than other mines. The non-carcinogenic effects, estimated by comparing the average As exposure with corresponding reference dose were determined by hazard quotient (HQ) values, which were less than 1.0 via ground water and rice intake in SD, NS, and MB mines. This implied that the non-carcinogenic toxic effects, due to this exposure pathway had a greater possibility to occur than those in other mines. Besides, hazard index (HI) values, representing overall toxic effects by summed the HQ values were also greater than 1.0 in SD, NS, JA, and IA mines. This revealed that non-carcinogenic toxic effects were generally occurred. The As contaminants in all selected mines exceeded the TCL values for target cancer risk ($10^{-6}$) through ground water ingestion and rice intake. However, the As level in soil was greater than TCL value for target cancer risk via inadvertent soil ingestion pathway, except for KK mine. In TCL values for target hazard quotient (THQ), the As contaminants in soil did not exceed such TCL value. On the contrary, the As levels in ground water and polished rice in SD, NS, IA, and MB mines were also beyond the TCL values via ground water and rice intake. This study concluded that the health risks through ground water and rice intake were greater than those though soil inadvertent ingestion and dermal contact. In addition, it suggests that the abandoned mines to exceed the risk-based TCL values are carefully necessary to monitor for soil remediation.

국내산 변질미와 저장 중 미곡에 발생하는 곰팡이로는 Aspergillus 속이 가장 많이 관찰되었으며, 분리한 곰팡이들의 일부는 아플라톡신 생성능을 보유하고 있었다. 대부분의 미곡시료에서는 Fusarium, Aspergillus, Penicillium, Alternaria 속 등의 다양한 곰팡이가 발생했으나 시료 내 아플라톡신 발생이나 오염수준은 허용기준치 이하로 미미한 반면 Fusarium 독소인 데옥시니발레놀, 니발레놀, 제랄레논, 푸모니신 등의 발생은 빈번하였다. 미곡종합처리장의 벼와 가공부산물의 경우, 곰팡이 및 곰팡이독소의 발생수준이 가공단계를 거칠수록 감소하여 백미에서 가장 낮았다. 현재, 벼의 가공부산물을 포함한 국내산 미곡의 경우, 아플라톡신 보다 Fusarium 곰팡이독소에 대한 안전관리가 더욱 필요한 것으로 판단된다.

This study was conducted to investigate the supplementary effects of Suwon 464 developed by Rural Development Administration, which has over two times of dietary fiber content compared with normal rice (Ilpum), on lipid metabolism in diabetic mice. We supplied 5 kinds of experimental diets (com starch diet as a control (CO), Ilpum polished rice diet (IP), Ilpum brown rice diet (IB), polished rice diet (SP) and brown rice diet (SB) of Suwon 464) to diabetic mice for 8 weeks, after analyzing dietary fiber contents of 5 experimental diets. Diet intake, body weight, organ weights, and lipids levels of serum, liver and feces were measured. The dietary fiber contents in CO, IP, IB, SP, and SB diets were 1.0, 1.2, l.4, 1.4, and 2.0% respectively. Body weight and liver and epididymal fat pad weights were lower in SB group than the other groups though there was no significant difference in diet intake among experimental groups. The concentrations of serum triglyceride was lower in SP and SB groups than CO and IP groups. The levels of hepatic total lipid and total cholesterol were significantly lower in SP and SB groups than CO group, and the level of hepatic triglyceride was lower in IB, SP and SB groups than CO group. The levels of total lipid and triglyceride excreted in feces were higher in IB, SP and SB, and the level of total cholesterol in feces was higher in SP and SB groups than CO group. These results suggested that the high dietary fiber rice (Suwon 464) decrease the triglyceride or total cholesterol concentrations of serum and liver by increasing of fecal lipid excretion in diabetic mice.

To assess the relationship between Cd fraction in paddy soils and Cd in polished rice, soils and rice were analyzed at the 3 Cd contaminated paddy fields near closed mines. Major Cd fractions of A field were organically bound (62.6%) and Fe-Mn oxide bound (25.3%) forms. In case of B field, major Cd fractions of B1 field were carbonate bound (46.3%) and Fe-Mn oxide bound (31.6%) form whereas B2 field were residual (54.3%) and carbonate bound (21.8%) form, respectively. It showed a huge difference of Cd fraction each other. 0.1M HCl extractable Cd in soil was positively correlated with Cd in rice. Specially, the ratios of 0.1M HCl extractable Cd against total Cd content in soils were 13.7%, 2.6%, and 0.45% in A, B1, and B2 fields, respectively. These ratio were largely affected with Cd uptake to rice grain. Also, exchangable, Fe-Mn oxide bound, and carbonate bound form, which are partially bioavailable Cd fraction to the plant, were positively correlated with Cd in rice while organically bound and residual form was not correlated. Multiple regression equation was developed with Rice Cd = -0.02861 + 0.07456 FR 1(exchangeable) + 0.00252 FR 2(carbonate bound) + 0.001075 FR 3(Fe Mn oxide bound) - 0.00095 FR 4(organically bound) - 0.00348 FR 5(residual) ($R^2=0.7893^{***}$) considering Cd fraction in soils.

The objective of this study was to evaluate the nutritive value of polished rice (PR) vs unpolished rice (UPR) as a potential feedstuff for sheep in order to use as a replacer to corn in sheep diet, and as well as to present the application in the formulation of cattle diet. Six corriedale ewe were randomly assigned to each treatment. UPR and PR were provided as a dietary treatment together with timothy grass as a basal diet in a crossover design for two period with 15-d duration for each period. The ratio of experimental and basal feeds were 33.3% and 66.7%, respectively. The differences in the total digestible nutrient (TDN) contents between sheep and cattle was determined according to the references. The number of data collected sheep and cattle was 9 and 17, respectively. The PR showed higher nutrients digestibility than UPR. Similarly, higher TDN content was observed PR than UPR (p < 0.05). As a result, the replacement of corn in the formulate feed with UPR and PR feed rice could be possible with the ratio of 91.2% and 100.0%, respectively. The result of comparation the TDN contents of UPR and PR in sheep and cattle, the PR has no difference in the nutritive value which suggests the applicability of the results of sheep to cattle. On the other hand, UPR has known to have different nutritive value between sheep and cattle, so caution should be taken when preparing formula feeds for cattle.
