Nondestructive methods such as ultrasonic and magnetic resonance imaging systems have many advantages but still much expensive. And they do not give exact color information and may miss some details. If it is allowed to destruct a biological object to obtain interior and exterior informations, 3D image visualization model from a series of sliced sectional images gives more useful information with relatively low cost. In this paper, a PC based automatic 3D visualization system is presented. The system is composed of three modules. The first module is the handling and image acquisition module. The handling module feeds and slices a cylindrical shape paraffin, which holds a biological object inside the paraffin. And the paraffin is kept being solid by cooling while being handled. The image acquisition modulo captures the sectional image of the object merged into the paraffin consecutively. The second one is the system control and interface module, which controls actuators for feeding, slicing, and image capturing. And the last one is the image processing and visualization module, which processes a series of acquired sectional images and generates a 3D volumetric model. To verify the condition for the uniform slicing, normal directional forces of the cutting edge according to the various cutting angles were measured using a strain gauge and the amount of the sliced chips were weighed and analyzed. Once the 3D model was constructed on the computer, user could manipulate it with various transformation methods such as translation, rotation, and scaling including arbitrary sectional view.

Multispectral scanner data collected by LANDSAT-1 over the mid West Sea of Korea were analyzed and interpreted for delineation of coastal features and turbidity distribution patterns during different portions of the tidal cycle. Imagery from two successful LANDSAT-1 overpasses of the area in October 1972 and in October 1973 had been used to prepare schematic maps of coastal features and turbidity distributions. Color composite imagery of LANDSAT MSS 4, 5 and 7 gave the best representation of shorelines, coastlines and tidal flats. MSS 5 imagery was most effective in differentiating relative turbidity levels through density slicing techniques. Referring to the tidal power development of Garolim Bay, the basin area measurements assuming dyke construction at the bay entrance, have been carried out on the coastal reature maps comiled from LANDSAT imagery, and those results were correlated with existing data. General areal patterns of surface turbidity distribution in the study area revealed close similarity with bathymetry of the area. Synoptic circulation patterns were also well discriminated from the LANDSAT imagery using the suspended sediment as a tracer.

Blanching시간, chemical dipping, 냉동방법 및 저장기간이 냉동양송이의 texture, 색깔 및 수율에 미치는 영향을 연구한 결과는 다음과 같다. Whole mushroom의 경우 5분간 blanching한 것은 1-2분간 blanching한 것 보다 shear press값이 현저히 높았으며, 저장기간이 연장됨에 따라 shear press값이 매우 유의성 있게 증가했다. 그러나 냉동방법은 texture에 유의성 있는 영향을 주지 않았다. Sliced mushroom의 경우 blanching시간이 길어짐에 따라 shear press 값이 증가하기는 하나 유의성은 없었으며, 저장기간이 연장됨에 따라 texture가 현저히 tough 해짐을 알 수 있었다. 그리고 시료의 texture를 관능적으로 측정한 결과는 대체적으로 shear press 결과와 유사한 경향을 보였다. Chemical dipping 방법은 blanching 시간을 짧게하여 냉동양송이의 수율을 높히면서 저장중 색깔의 변화를 방지하는데 효과적이었으며, 특히 whole mushroom의 수율은 상당히 증진시킬 수 있었다. Sliced mushroom의 경우는 blanching time을 2분이하로 단축시키면 rotary slicer로 절단작업을 할 때 조직이 부스러져 생기는 중량손실이 증가하므로 2분 또는 그 이상의 blanching time이 필요했다.

Ultrasonic and magnetic resonance imaging systems are used to visualize the interior states of biological objects. These nondestructive methods have many advantages but too much expensive. And they do not give exact color information and may miss some details. If it is allowed to destruct some biological objects to get the interior and exterior information, constructing 3D image from the series of the sliced sectional images gives more useful information with relatively low cost. In this paper, PC based automatic 3D model generator was developed. The system was composed of three modules. One is the object handling and image acquisition module, which feeds and slices objects sequentially and maintains the paraffin cool to be in solid state and captures the sectional image consecutively. The second is the system control and interface module, which controls actuators for feeding, slicing, and image capturing. And the last is the image processing and visualization module, which processes a series of acquired sectional images and generates 3D graphic model. The handling module was composed of the gripper, which grasps and feeds the object and the cutting device, which cuts the object by moving cutting edge forward and backward. Sliced sectional images were acquired and saved in the form of bitmap file. The 3D model was generated to obtain the volumetric information using these 2D sectional image files after being segmented from the background paraffin. Once 3-D model was constructed on the computer, user could manipulate it with various transformation methods such as translation, rotation, scaling including arbitrary sectional view.

The aim of this study was to determine the best processing conditions for producing of dried lean pork as a ready-to-serve product without using large-scale machines. Lean pork sausage was produced using 1.27% sodium chloride, 0.075% sodium polyphosphate, 0.06% sodium ascorbate, 0.075% sodium pyrophosphate, 0.009% sodium nitrite, 0.009% dextrin, 0.11% sodium glutamate and 1.4% spice mixture. The most appropriate slice thickness for drying was examined by slicing the sausage at a 0.5, 1 and 2 cm thickness. The drying temperatures were determined by drying the sausage slices at 35, 48 and $68^{\circ}$. The total drying period was for 12 hr, In order to examine the ability of this process to sterilize the pork, the raw meat materials were inoculated with Escherichia coli (E. coli). The optimal conditions for producing lean pork sausages were a 2 cm slice thickness and drying temperature of $68^{\circ}C$ for 12 hr, The moisture content water activity, color, hardness and pH were measured in the dried product. The product had a moisture content of 47.5% and a water activity of 0.93. There was a 47.7% percentage reduction in moisture. The dried product tested negative for E. coli even though the raw meat materials been inoculated with E. coli.
