This study was focused on the pork market analysis of the Philippines and the export prospect of Korean pork to the Philippines. The main results are as follows; first, the Philippines have relied on import some quantity of pork consumption every year because climate condition is unfavorable for pig raising and production technologies are undeveloped. Major exporting countries to the Philippines are Germany, Canada, Belgium, Denmark, France, Holland. Second, Korea exported pork of 2,885 tons to the Philippines from Jan. 2004 to Oct. 2004. It was 5.7% of total import pork Third, pork of skinning was 20% higher than the pork of scalding in the consumer price of pork in the Philippines. The consumer price of pork in Korean pork market was 281% in belly, 118% in loin, 106% in leg, 117% in tenderloin higher than the Philippines pork market. Fourth, the export of Korean pork to the Philippines depends on the price of Korean pork market entirely for future, but low grade part of pork and byproducts can be exported to the philippines because consumer price of pork in the Philippines is low compared to Korean pork market.

Nine Korean native cattle were purchased from a beef cattle farm. Immediatly after slaughtering and skinning, each carcass was split into left and right sides and the one half was kept as a control, the other one was electrically stimulated by using 400v stimulator for 1 min. All samples were analyzed for shear force value, ATP and biochemical changes to investigate the effect of electrical stimulation during storage at $5^{\circ}C\;and\;15^{\circ}C$. The amount of lactate of electrically stimulated (E.S.) meat showed a rapid increment compared with that of control (p<0.01). E.S. treatment caused a rapid drop of pH value. Initial pH decreased from 6.85 to 6.38 in M. semitendinosus and from 7.0 to 6.58 in Triceps brachii by E.S. treatment (p<0.01). Electrically stimulated muscle showed decrease (34.67%) in ATP to $5.74{\mu}mole/g$ from $8.78{\mu}mole/g$ of unstimulated meat. ATP of the electrically stimulated muscle stored at $15^{\circ}C$ and $5^{\circ}C$ was degraded faster than that of control until 6 hours post-mortem (p<0.05). The tenderness of meat after aging was improved significantly by electrical stimulation with lower shear force value than that of untreated meat (p<0.01).

This study was performed to evaluate the effectiveness of biological critical control points using the genetic profile of Escherichia coli isolates from pork cutting plants. Samples were collected from carcasses, equipment (knife, table, glove, transport belt, boning and skinning machine), the environment (wall and floor), and meat cuts during the cutting process from two plants. Pulsed-field gel electrophoresis (PFGE) was used to characterize the E. coli isolates. An identical genotype was detected from the carcasses, equipment, environment, and final meat cuts, and showed that the incoming carcasses, which were contaminated during transportation from slaughterhouses, were a major source of E. coli that was spread throughout processing. Also, consistent cross-contamination due to improper cleaning and disinfection procedures was another possibility. As a result, incoming carcasses and cleaning procedures should be considered critical control points in pork cutting plants, since a heating step is not used to inactivate microorganisms. Furthermore, the high rate (59.6%) of E. coli isolation indicates E. coli can be a good indicator in livestock processing plants even though it has genetic diversity.

The purpose of our research is to efficiently deform a 3D models which is composed of a triangular mesh and a skeleton. We designed a novel inverse kinematics (IK) solver that calculates the updated positions of mesh vertices with fewer computing operations. Through our user interface, one or more markers are selected on the surface of the model and their target positions are set, then the system updates the positions of surface vertices to construct a deformed model. The IK solving process for updating vertex positions includes many computations for obtaining transformations of the markers, their affecting joints, and their parent joints. Many of these computations are often redundant. We precompute those redundant terms in advance so that the 3-nested loop computation structure was improved to a 2-nested loop structure, and thus the computation time for a deformation is greatly reduced. This novel IK solver can be adopted for efficient performance in various research fields, such as handling 3D models implemented by LBS method, or object tracking without any markers.
