The objective of this study is to find the optimal cooking condition of rice for the cold chain as home meal replace-ment (HMR) products. Two types of rice varieties were cooked either on an electric rice cooker (ERC) or a super-heated steamer (SHS) with different concentrations of beef bone broth added before cooking. Cooked rice wasstored at 5oC for 3 days and the quality was analyzed by moisture content, color, reducing sugar content, textureprofile, and sensory evaluation. The results indicate that retrogradation of cooked rice prepared using SHS can bereduced during cold storage by the addition of beef bone broth. Also, the addition of more than 40% of beef bonebroth caused a deterioration in the quality of the cooked rice, and it appears that the addition of 10-20% of bonebroth is optimal for the overall quality of the cooked rice during cold storage.

In this study the effect of rice type and cooking methods on the quality of cooked rice during cold storage wereinvestigated to develop home meal replacement (HMR) products. The chemical and physical properties and sensoryquality of rice were studied by rice type (Oh-dae-mi, Baek-jin-ju S., and Indica) and cooking methods (electric ricecooker and super heated steamer). Cooked rice was stored at 5oC for 3 days and the moisture content, color, reduc-ing sugar content, texture profile, and sensory evaluation were analyzed. The results show that rice type Baek-jin-ju S. has the highest moisture content and that color and textural properties are maintained during storage. Ricecooked with an electric rice cooker has higher moisture content and better color properties; however, rice cookedwith a super heated steamer shows higher reduced sugar content with a softer texture. The selection of Baek-jin-juS. and cooking with a super heated steamer have a positive effect on the quality of rice during cold storage.

KWNP의 특정 손상에 대한 회복 효과에 대한 과학적인 접근을 하기 위해서 본 연구를 수행하였다. 실험은 STZ를 복강 주사하여 당뇨를 유발, 220mg dL-1 이상인 실험동물을 이용하여 수행되었으며 방사선 전신 조사 실험군과 KWNP 처리군 간의 각 항목 분석치를 비교, 분석하였다. 실험 5주간의 체중증가율은 방사선 처리군과 당뇨군 모두 대조군에 비하여 낮게 나타났으며 특히 당뇨군에서는 통계적으로 유의적으로 낮았다. 정소와 비장, 또 당뇨

세포에 미치는 염화수은(II)과 이온화 방사선의 영향과 수은 처리 전 후 방사선 조사 시 그 상호 작용에 관해 알아보고자 본 연구를 수행하였다. 염화수은(II)의 독성정도를 알아보기 위하여 사람의 자궁암 세포에 농도별로 염화수은(II)을 처리하였다. 세포의 생존율은 3가지 농도(1,0. 1,0. 0.01 μM)모두에서 유의하게 감소하였으며 이미 0.1 μM에서 약 73%의 생존율이 감소하는 것으로 나타났다. 염화수은(II)과 방
