To improve the individual packaging method and extend the shelf life of hair tail(Trichiurus japonicus), salted an unsalted hair tail chunk (cut in 8-10cm) were packaged in laminated plastic film bag(Nylon/PE: $20{\mu}m,\;12{\times}15cm$) filled with with free-$O_2$ absorber, in vacuum, and stored at 0 and/or $5^{\circ}C$. The other samples were packaged in plastic foam trays, overwraped with oxygen permeable film(control), and stored at same temperature. Volatile basic nitrogen (VBN), trimethylamine (TMA) and viable cell counts (VCC) were progressed with increase of storage time, but thiobarbituric acid (TBA) values decreased gradually after reaching at a maximum peak in 5-15 days. Judging from 4 chemical components, VBN was the most available component in quality judgement of hair tail chunk and its upper limiting content was 29 mg%. Regression equation for shelf life prediction of hair tail chunk with sensory evalution and VBN component was determined.

In order to evaluate the nutritive value of the forage plants in South Sulawesi, Indonesia, 266 samples (61 grasses and 65 legumes grown in the dry season, 60 grasses and 80 legumes grown in the rainy season) were collected from the highland and lowland in 1998 to 2000, and were subjected to the determination of chemical composition and digestibility. The least-squares analysis of variance demonstrated that the in vitro dry matter digestibility (IVDMD) of grasses was not significantly affected by season or altitude. On the other hand, the some proximate components and cell wall components were significantly affected by season and altitude including the season${\times}$altitude interaction. For the legumes, the in vitro neutral detergent fiber digestibility (IVNDFD) and cellulose content were significantly affected by season. On the other hand, the ether extract (EE) content was significantly affected by season and altitude. The interaction of the season${\times}$altitude for IVDMD, of the year${\times}$season for some proximate components and of the year${\times}$season and the season${\times}$altitude for some cell wall components were significant. These results indicate that the forages grown at highland in dry season have a relatively high quality. The means of the total digestible nutrient (TDN) content estimated from IVDMD in grasses and in legumes were 50.3% and 57.4%, respectively, and the crude protein contents were 7.7% and 17.6%, respectively. The correlation coefficients between IVDMD and the contents of crude fiber, neutral detergent fiber and acid detergent fiber were relatively high in all of forage plants, suggesting that these components would provide an accurate prediction of digestibility or TDN content. A close relationship between IVNDFD and lignin content indicates that the lignin would be the most accurate predictor of cell wall digestibility.

The aim of this study was to compare ultrasonography with video-otoscopy for the evalution of the external ear canal and the tympanum. Fifty dogs with clinical signs ot the bilateral ear diseases were examined using otoscopy under general anesthesia. Ultrasonographic examination was performed with an 11 MHz linear-arrary probe and a 6.5MHz convex probe, with the external ear canal filled with saline. Saline functioned as a contrast media and enhanced image quality of ultrasonography. The images of 100 ears before and after the ear cleansing were obtained at otoscopy and ultrasonography. On the video-otoscopic images, the tympanic membrane was identified in 59 ears before the ear cleansing and 91 ears after cleansing. On the ultrasonography, the tympanic membrane was detected in 98 ears before the ear cleansing and in all ears after cleansing. With these results, it was concluded that ultrasonography with infusing saline into the ear canal, could be a useful diagnostic procedure to identify the tympanic membrane in otitis dogs.

Present studies were conducted to investigate the developmental stage and the location of embryos in the reproductive tract at various times after ovulation, the morphologically normal after thawing of embryos preserved in liquid nitrogen, and the survival after transferring frozen-thawed embryos. The results obtained were as follows: 1. Embryo stage and location in the reproductive tract after hCG administration. For the investigation of embryo stage and location in the reproductive tract after ovulation, rabbits were laparotomized at 24, 40, 48, 72 and 120 hrs post hCG injection, simultaneously with mating. the oviducts and uteri were flushed out with PBS medium containing 50% rabbit serum, respectively. 1) Most of embryos was remained in the oviduct within 48 hrs, with the lapse of time, embryos were started to move to uterus and shifted in uterus at 72 hrs after hCG injection. 2) The representatives of embryos stage collected at 24, 40, 48, 72 and 120 hrs were 1-cell(60.4%), 8-cell to early morula (52.3, 39.3%), late blastocyst (95.5%) stages, respectively. 2. Morphological normality and survival of the frozen-thawed embryos. For the evalution of the quality and viability on the frozen-thawed embryos, immediately after thawing, embryos were assessed by morphologically normal under a dissecting microscope, and a further test of frozen-thawed embryos was made by transferring the morphologically normal embryos to the uteri of recipient rabbit induced pseudopregnancy by the injection of hCG at the time of hCG injection in donor rabbits. 1) The propotions of embryos which a, pp.ared morphologically normal was higher when 8-cell (85.7%) and morula(90.5%) were used for freezing than when 4-cell (66.7%) and blastocyst (75.8%) were used. 2) Preganacies were observed at Day 15 after transfer of frozen-thawed 8-cell (7/13), morula (19/42) and blastocyst (3/19) but not after transfer of embryos at 4-cell stage.

In these days the floor vibration is beginning to make its appearance of the environmental dispute in apartment building. Standard floor system are suggested for the settlement of this issue by government. The sound of floor impact sound is needed to secure comfortable quality in housing. Also, it is required an accurate analysis and a proper evaluation for floor vibration. Refine model is necessary for the floor system of housing to analyze accurately the floor vibration. But this refine model is not efficient because it is required so much running time for vibration analysis and it is difficult of modeling of standard floor slab. In this paper, new modeling methods of standard floor slab are proposed for the accurate rigidity evaluation. By using the new modeling method, the accurate vibration response can be obtained and can accurately evaluate the rigidity of standard floor system with resilient materials. Therefore the proposed modeling method is of practical use for vibration analysis of floor system of apartment building.

This study was performed to compare the changes of quality in citron(Citrus junos Sieb) juice between sampleII stored at 5$^{\circ}C$ for 1 year after extraction and sampleI made from raw citrons by the belt-pressing extraction method. Compared with sampleI, the soluble solid of sampleII was decreased more than 1$^{\circ}$brix, and the moisture increased 3%. The acidity reduced from 5.83 to 5.23 at the pH rose from 2.68 to 2.84. Although it decreased more than 50% in vitamin C and over 20~30% in amino acid, the changes of the other proximate components, amino nitrogen and free sugar content were very little at the range 0.1~1.0%. Volatile compounds in citron juices between sampleI and II were analyzed by GC and GC-MS. Sample I and II showed about 70 of volatile compounds. But only 13 compounds were identified by mass spectrometer. Major volatile compounds were aromatic compounds of limonene, terpinene, terpineol and terpinolene. Amounts of volatile compounds in citron juices depended on the storage period. The recovery of volatile compounds of citron juices, reduced 30~50% after storage for 1 year and the trace component disappeared during storage. The sensory characteristics including color, aroma, taste and overall acceptability and sugar recipe were not significantly.

Pork cutlets containing ginseng powder 1% + ginseng distillate 1%(P1/D1), ginseng powder 2%(P2), ginseng powder 1.5% + ginseng distillate 1.5%(P1.5/D1.5) and ginseng powder 3%(P3) were manufactured and compared with the control(no ginseng powder and distillates) in meat quality, sensory evaluation and flavor intensity. The L values were significantly lower and a values were significantly higher for pork cutlets containing ginseng additives as compared to the control. The pork cutlets containing ginseng powder and distillates were higher in hardness only at the beginning stage, but no significant differences in springness, cohesiveness and chewiness among the treatments were observed during storage at -20$^{\circ}C$ for 8 weeks. Flavor analysis indicated that spathulenol, panasinsanol, neointermedol and ginsenol were responsible for ginseng flavor. The sensory panels detected most intense ginseng flavor and taste for pork cutlet which contained combination mixtures of ginseng powder 1.5% and distillate 1.5%. In conclusion, sensory panels evaluated that ginseng distillates produced intense ginseng flavor and enhanced ginseng flavor when used as mixtures with ginseng powder. Therefore, ginseng distillates can be used as a natural antioxidant and flavor enhancer in pork products.

The pysicochemical and bacteriological properties of yogurts made by single or mixed cultures of L. bulgaricus FRI025 and S. thermophilus CHI were investigated. L. bulgaricus FRI025 which was isolated from raw milk was selected as starter culture among 22 strains of lactic culture by measuring viscosity, flavor, growth and acid production ability. The acid production and number of viable cell were increased by using L. bulgaricus FRI025 and S. thermophilus CHI together in ratio of apporximately 1:1. The pH, titratable acidity, viable cell number and viscosity of yogurt were 4.08, 1.14%, $2.5{\times}10^{10}/ml$ and 2100 cp after 9 hours incubation at $40^{\circ}C$, respectively. The pH and viable cell number were decreased on the other hand titratable acidity and viscosity were increased after 7 days of storage at $4^{\circ}C$. The changes of quality did not show significantly after storage. The selected starter was much higher than commercial yogurt starter in the acid production and growth of starter. The yogurt nanufactured with selected starter was better than with commercial yogurt in sensory evalution such as taste, texture, flavor and overall acceptability.
