This study was carried out to obtain basic data on Korean traditional Meju collected from 18 regions (TM1~TM18) in Korea and to define and control quality. The shape of Meju was mostly rectangular and the weight was 0.84~2.04 kg. The physicochemical analysis showed: pH, 5.31~8.21; total acidity, 0.91~2.74%; moisture content, 4.79~42.16%; and soluble protein content, 41.37~23.48%. Hunter color values for L (lightness), a (redness), and b (yellowness) ranged from 39.07~67.92, 3.57~8.87, and 7.48~20.67, respectively. The amino nitrogen contents of all samples were in the range of 257.29 to 839.58 mg% and TM13 showed the highest content (839.58 mg%). Total viable cells, yeast and mold counts of Meju were 8.43~5.91 log CFU/g, 2.48~5.19 log CFU/g, and 3.42~7.48 log CFU/g, respectively. Based on the results, it is proposed that quality standards and management of Meju fermentation conditions and information about different varieties of soybeans used should be made available.

한국 남성 시신의 온몸을 연속절단하여 절단면영상을 만들었다. 절단면영상에서 구조물의 테두리를 그리면, 그 구조물을 3차원영상에서 구조물의 테두리를 그리면, 그 구조물을 3차원영상으로 만드는 등 그 활용도가 높아진다. 따라서 저자들을 다리에 이어서 팔 구조물도 구역화하기로 하였다. 왼팔의 절단면영상 628개에서 구조물 91개(피부 1개, 팔뼈 32개, 팔근육 49개, 동맥 6개 및 신경 3개)를 구역화하였다. 이 과정에서 구조물의 테두리를 이전보다 더욱 빨리 그리는 방법을 개발하였다. 포토샵에서 절단면영상을 필터링한 다음에 테두리를 빠른선택도구 등으로 그렸고, 컴버스천 소프트웨어에서 보간하여 테두리를 자동으로 만들기도 하였다. 관상구역화영상과 시상구역화영상, 연속절단면영상 둘러보기 소프트웨어, 부피 3차원영상과 표면 3차원영상을 만들어서 구조물의 테두리를 올바르게 그렸는데 확인하였다. 이 연구에서 만든 팔의 구역화영상을 절단면영상과 함께 퍼뜨리면, 다른 연구자가 팔의 3차원영상과 여러 소프트웨어를 만들 수 있으며, 나아가 의학 교육과 연구를 위해 폭 넓게 쓸 것으로 기대된다. Whole body of a Korean male cadaver was serially milled to make sectioned images. Segmentation of various anatomical structures can expand the utilization of the sectioned images such as three-dimensional(3D) reconstuction of the structures of real human. Following previous outlining of lower limb's structures, we decided to make segmented images of upper limb's structures in detail. Ninety-one structures(a skin, 32 bones, 49 muscles, 6 arteries, and 3 nerves) in the left upper limb were segmented in 628 sectioned images. While doing this, we developed more efficient technique for segmentation. To draw the outlines of various structures more quickly, sectioned images were filtered first and then outlines were drawn by 'quick selection' tool and other tools on the Photoshop. Also, outlines were automatically generated by interpolation using Combustion software. We made coronal and sagittal segmented images, browsing software of the serially sectioned images, volume 3D images, and surface 3D images for verifying segmentation. These segmented and sectioned images of the upper limb are expected to help other researchers make 3D images and various software of upper limb and to have widespread applications in both medical learning and research.

The properties of rice were studied on five rice cultivars (Ilpumbyeo, Samkwang, Goami-4, Dodamssal, and Thai rice), and employed two kinds of saccharification treatment methods (treatment : rice shape, treatment II: grinding rice shape). Thai rice showed differences in width and length when compared to other cultivars of rice, and the Goami 4 had the lowest thousand-grain weight. The Goami4 and Dodamssal each showed high contents of amylose and resistant starch, and the water absorption rate was close to maximum at 90 minutes as well as the highest level of Goami 4 at all times. The qualities of highest water-binding capacity, solubility and swelling power was most significant in Thai rice. The lowest hardness level of wet rice resulted in the lowest hydration-related characteristics. High amylose content rice, in particular, showed low sugar content and slightly increased sugar content as the saccharification process improved (treatment II). On the other hand, high amylose cultivars had the same high degree of hardness as boiled rice. From these results, the Dodamssal was found to have the lowest viscosity at all temperatures but highest viscosity during the saccharification process, suggesting it may be successfully implemented as a thickener in rice beverage processing. The purpose of this study was to attempt to provide basic data on the development of rice beverage manufacturing technology, based upon the quality characteristics related to beverage processing of rice cultivars.

This study investigated the effects of Goami 2 on the properties of Garaetteok. The moisture, crude protein, crude lipid and crude ash contents of the rice were 16.02, 5.40, 1.87 and 0.77%, respectively. The amylose contents (32.16%) and total dietary fiber contents (9.03%) were the highest in Goami 2. The water binding capacity of Goami 2 (167.84%) was higher than general rice flour. Using a rapid visco analyzer (RVA), the initial pasting temperature of Goami 2 was found to be the highest; also, the peak viscosities of Goami 2 were higher than general rice powder. To assess the effect of Goami 2 on the quality characteristics of Garaetteok, the rice-cake was made by adding various amounts of Goami 2 (0, 10, 20, 30, and 40% w/w) to rice. It was observed that higher the amount of added Goami 2, lower were the grades. In terms of the color values of Goami 2 addition, the L-values of Garaetteok were lower with increasing amount of Goami 2; addition of 40% Goami 2 had the lowest value. The textural properties (hardness) also showed that tteok containing the greater amounts of Goami 2 were considerably harder compared with the control. Sensory preference tests revealed that addition of less Goami 2 had the highest scores for appearance, color and overall acceptability, and the Goami 2 added was lower than control. Therefore, as compared to others cultivars, rice flour proved the most acceptable for the preparation of Garaetteok with cultivar rice.

The sectioned images (SIs) of the pelvis from a female cadaver are the best source of realistic threedimensional (3D) models of the female urogenital system. The purpose of this research is to present SIs and outlined images of the female pelvis with improved quality, which may be used to produce 3D models to simulate virtual dissection or surgery of the female urogenital and adjacent structures. A pelvis of Korean female cadaver which preserved buttock curve was scanned with 3T MR and CT machines. The pelvis was embedded and milled at 0.1 ㎜ intervals. All sectioned surfaces were photographed to create horizontal SIs. On the Photoshop, 73 structures were outlined in the SIs to create outlined images. Once the structures were outlined, volume and surface models of the structures could be produced. A total of 222 MRIs and 222 CTs of a female pelvis were obtained. 2,220 SIs of the pelvis were obtained (0.1 ×0.1×0.1㎣-sized voxels; 48 bits color). 222 outlined images of 73 structures were prepared at 1㎜ intervals. Once the structures were outlined, 3D volume and surface models of the structures were produced without the help of the computer programmers using MRIcro and Maya software. We have produced high quality SIs of the female pelvis accompanied by corresponding MRI and CT images. 3D volume and surface models of the female pelvic structures have been constructed. These computerized models may serve as the basis for future realistic medical simulation programs that may enhance clinical understanding of pelvic anatomy.
