Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherpy seems a logical choice for cancer chemotherapy. The Mitomycin C(MMC) adsorbed by the activated charcoal particles(CH) is relatively released when the drug concentration surrounding the carbon particles becomes low in the peritoneum of the peritoneal cavity. For the intraperitoneal chemotherapy on the advanced gastric adenocarcnoma, mitomycin C adsorbed on activated carbon particles was administered in the peritoneal cavity just before abdominal wall closure. The closed drainage tubes were inserted in the peritoneal cavity and clamped for tuo hours after completion of operation. MMC concentrations were serially measured in peritoneal fluid, plasma and urine at 2hour, 48 hour, 72 hour and 168 hour following its administration in order to study the efficacy of the MMC-CH as a drug delivery system. There were minimal toxicities in born marrow, liver, and gastrointestinal system after intraperitoneal MMC-CH administration. The data of this study suggested that MMC-CH may have a somewhat more beneficial effect than surgery alone when administered in optimal dose and schedules, but the MMC concentration of the peritoneal fluid was not sufficient to eradicate remnant cancer cells, and effective duration of maintenance was only below 24 hours in the peritoneal fluid and plasma.

The movement lifting up and supporting the object with arm in sports or daily life can bring about the several disease or injure to a joint, bone and muscle for great weight, as you overuse your power. Therefore it is a important study to find out the mechanical structure and principle of arm's movement. Because human's body is different from another object. It is not simple. So biomechanist make clear relation with the power and movement by modelizing each segment of body into a rigid body and by substituting direct kinetics problem for indirect kinetics problem. This study developed the kinetical modeling of right arm's segment at lifting up and down of dumbbell by using korean's data. It is useful to foresee finding out the power and moment in sports movement or daily activity of arm

Finding human faces automatically in a scene is a difficult yet significant problem. This paper proposes a method for detecting face regions from a complex background, and describes the experimental results. We perform face location based on the observation that human faces are characterized by their color information and texture features as follows. Firstly we construct a face chromatic histogram in hue and saturation chromatic space. Secondly we use the chromatic histogram to detect skin pixels from the input image. Thirdly a face texture model is constructed by calculating inertia, inverse difference and correlation of facial images. Finally the locations of the face region are determined by face texture features.
