A hybrid image processing system which automatically distinguished lean tissues in the image of a complex beef cut surface and generated the lean tissue contour has been developed. Because of the in homegeneous distribution and fuzzy pattern of fat and lean tissue on the beef cut, conventional image segmentation and contour generation algorithm suffer from a heavy computing requirement, algorithm complexity and poor robustness. The proposed system utilizes an artificial neural network enhance the robustness of processing. The system is composed of pre-network , network and post-network processing stages. At the pre-network stage, gray level images of beef cuts were segmented and resized to be adequate to the network input. Features such as fat and bone were enhanced and the enhanced input image was converted tot he grid pattern image, whose grid was formed as 4 X4 pixel size. at the network stage, the normalized gray value of each grid image was taken as the network input. Th pre-trained network generated the grid image output of the isolated lean tissue. A training scheme of the network and the separating performance were presented and analyzed. The developed hybrid system showed the feasibility of the human like robust object segmentation and contour generation for the complex , fuzzy and irregular image.

Many secreted proteins have disulfide bonds that are important for their structure and function. Protein disulfide isomerase (PDI, EC 5.3.1.4.), an enzyme that catalyzes the formation and rearrangement of thiol/disulfide exchange reactions, is a resident of the endoplasmic reticulum (ER). The subcellular localization and its function as catalyst of disulfide bond formation in the biosynthesis of secretory and cell membrane proteins suggest that PDI plays a key role in the secretory pathway. We have isolated a cDNA encoding protein disulfide isomerase from Bombyx mori(bPDI). It has been characterized under ER stress conditions (dominantly induced by calcium ionophore A23187, tunicamycin and DTT), which is known to cause an accumulation of unfolded proteins in the ER. Furthermore, It has also been examined for tissue distribution(pronounced at the fat body), hormonal regulation (juvenile hormone, insulin and juvenile +transferrin; however, it is not effected by transferrin alone), and the effect of exogenous bacteria (peak at 16 h after infection) on the bPDI mRNA expression. The results suggest that bPDI is a member of the ER stress protein group, and it may play an important role in exogenous bacterial infection in fat body, and that homones regulate its expression.

We conducted this study to analyze the effectiveness of a treatment called 12-week therapeutic recreation dance movement (TRDM) to elderly people in terms of health care and recovery. Forty two elderly people were participated in this study and divided into two groups with healthy (twelve) and unhealthy (thirty). After TRDM treatment, the muscular power was increased in both groups without statistical significance within and between groups. The flexibility, agility and balance were slightly increased in both groups. Although the elevation of muscular endurance was not significant between groups, it was statistically meaningful within groups. The results of body composition comparison did not reveal meaningful difference within and between groups. However, the amount of fat in serum and fat distribution percentages ware decreased in both groups. Both group appeared to be increased muscle mass. The level of body water was decreased in healthy group and increased in unhealthy group. Unhealthy group appeared to be decreased level of T-C, TG and LDL-C. In contrast, the unhealthy group revealed the increased level of HDL-C. These results demonstrate the effect of TRDM to elderly people. This effectiveness can be adapted for the protection and treatment of geriatics-related adult diseases such as diabetes, hypertension and hyperlipidemia.

The purpose of this study was to compare the growth development between age-matched 51 postmenarcheal girls (mean age 153.1$\pm$5.8 month) who were rapidly maturing and 51 premenarcheal girls (mean age 153.1$\pm$5.7 month) who were slowly maturing. Anthropometirc measurements were taken for height, body weight, body fat(%), waist and hip circumferences of subjects. These measurements of menarcheal girls were significantly higher than those of nonmenarcheal girls. There was no significant difference in BMI distribution between two groups. However, 43.2% and 20.0% respectively in the menarcheal and nonmenarcheal girls had body fat levels of 30% or above. There were significant differences in the anthropometric measurements during past 4 years from 3rd grade elementary school to present. The greatest difference between the two groups were the amount and the rate of increased height and body weight from age 9 to 10. Among menarcheal girls, height, body weight, BMI, and Röhrer index were positively related to the onset of menarche. Distinctively, there was a stronger relationship between age at menarche and anthropometric measurements when the girls were 5th grade elementary school children. These findings support that during childhood and puberty, obese girls grow faster and have earlier menarche. Furthermore, the importance of prevention of obesity was recognized in order to accelerate growth of height among the girls by delaying the age of menarche.

Vitellogenin was purified from the haemolymph of female pupae during egg formation of Bombyx mori using DEAE-cellulose column and its quantitative change in various organs with age ws examined by electrophoresis and immunodiffusion. Vitellogenin is distributed in the haemolymph, fat body, and over the egg maturation and especially maintainsa constant level in the haemolymph until just before emergence, indicating that vitellogenin in released into the haemolymph at the same amount as it is taken up by oocytes during pupal period. Immunologically vitellogenin was confirmed to be in the fat body until 7 days after pupation and to undergo a drastic decline thereafter. Also, the interaction of anti-ovary proteins with haemolymph proteins showed at least 3 homogeneous proteins, indicating that other proteins as well as vitellogenin are involved in egg formation.

The object of this study was to investigate the difference in physical and sensory properties of various premium ice creams. The physical properties of the various ice creams were compared by manufacturing brand. The water contents of the samples differed, with BR having the highest value at 60.5%, followed by NT and CS at 57.8% and 56.9%, respectively. The higher the water content, the lower Brix and milk fat contents in all samples. The density of the samples showed almost similar values in all samples (p>0.05). The viscosity of each ice cream had no effect on the water content in any of the brands. Before melting of the ice cream, the total color difference was dependent on the lightness, especially in the vanilla ice cream, owing to the reflection of light on the surface of the ice crystals. The CS product melted the fastest. In the sensory test, CS obtained a significantly higher sweetness intensity score but a lower score for color intensity, probably due to the smaller difference in total color, by which consumers might consider the color of CS as less intense. From this study, the cold chain system for ice cream distribution might be important to decide the physical properties although the concentration of milk fat is key factor in premium ice cream.

We have investigated the feasibility study, especially for optimal TR, to obtain 3-D MR neurographic imaging (neurograms or nervography) which shows the distribution of peripheral nerve fibers at the human forearm using 4.7 T magnet. To peform a successful formation of MR neurographic imaging, nerve signal should be separated from the other signal comes from surrounding muscle or fat, because nerves are usually embeded in muscle or fat. Generally, it is well known that nerve has shoter T1 value than that of muscle. Thus, repetition time was optimized to maximize the signal intensity defference between the muscel and nerve. We have also used spin-echo(SE) sequence with long echo time($60{\sim}90\;msec$) to enhance the different signal intensity between muscles and pheriperal nerves base on the fact that muscle tissue has longer T2 relaxation lime than that or nerve.

The purpose of this study was to classify female students' somatotypes, to investigate the relationship between five somatotypes obtained from anthropometric measurements and to examine the relationship between the spinal deformity and somatotypes. The subjects for anthropometric measurements were 844 female middle and high school students. The data were analyzed by cluster analysis, correspondence analysis, Duncan test, and T-test. The results were as follows. Cluster analysis on the factors extracted from directly measured items classified subjects into five types (middle height and a little slim type (39.6%), low height and a little slim type (13.1%), middle height and a little fat type (18.0%), tall and very fat type (7.7%), and very tall and standard type (21.6%). In examining the relationship between the normal people and those of the spinal deformity, the normal showed higher mean value in almost all the items of the girth, the depth, and the length. High school students had more spinal deformity in number than middle school students. The degree of deformity was higher in the right spinal deformity than in the left spinal deformity as the age increased. In terms of the distribution of the spinal deformity classified by the somatotype, Type 1 (middle height and a little slim type) and Type 5 (very tall and standard type) appeared the highest.
