To investigate the effects of packaging method and storage condition on meat quality, a total of eight pork loins were selected from a commercial meat plant at 24 hr postmortem. The loins were cut to 2.5㎝ thick steaks and were randomly assigned to the five treatment combination; vacuum packaging and submersion in chilled salt water(SCSW)(T1), non-vacuum packaging and submersion in chilled salt water (T2), vacuum packaging and storage in conventional refrigerator(SCR)(T3), non-vacuum packaging and storage in conventional refrigerator(T4), and wrap packaging and storage in conventional refrigerator(TS). All samples were stored at 0℃ for 20 days to measure color of meat(CIE L*, a*. b*), pH, drip loss, purge loss %, lipid oxidation (TBARS; thiobarbituric acid reactive substances) and total plate counts (TPC). CIE L* and b* value of SCSW(T1, 2) samples were significantly(P$lt;0.05) lower than SCR samples when they were measured at storage 20 days. The sample of SCSW(T1, 2) showed significantly(P$lt;0.05) lower pH than those of SCR(T3, 4, 5) during storage. The sample of SCSW(T1, 2) showed significantly(P$lt;0.05) higher Drip loss than those of SCR(T3, 4, 5) during 5 days storage. T2 showed the lowest purge loss % whereas T3 remarked the highest purge loss %. The samples of SCSW showed significantly(P$lt;0.05) lower TBARS than those of SCR during storage. TPC was samples of SCSW(T1, 2) showed significantly(P$lt;0.05) lower than other treatments. These results suggested that NVP(non-vacuum packaging) and SCSW could reduce purge loss and discoloration, and extend shelf-life of pork loin.

플라즈마 용사에 의한 ZrO2 (8wt% Y2O3) 코팅층의 미세조직과 마르텐사이트 상변태에 관한 연구

허성강,나형용,이주동,홍경태 대한금속재료학회(대한금속학회) 1992 대한금속·재료학회지 Vol.30 No.12

The microstructures and effect of the residual stresses on the stress induced martensitic transformation in plasma-sprayed ZrO₂(8wt% Y₂O₃) coatings were discussed in this study. Acoustic counts and hardness decreased with an increase of compressive axial(or radial) residual stress since martensitic transformation was repressed. The critical stress for inducing phase transformation increased and was influenced greatly by the residual stress as the deposition rate decreased. This is because stress intensification decreases as well with decreasing the deposition rate. Transformable equilibrium tetragonal phase precipitated only at bundaries, which are believed to have small cooling rates due to a collision between solid/liquid interfaces, and was transformed readily by applied stress. It was revealed that the critical stress depended not on the effective stress of Von mises criterion but on the residual stress(σ_(xy) σ_y or σ_z). This implies that martensitic transformation occurs predominently at these boundaries.

In order to evaluate the effect of vaccinantion for hog-cholera virus, sera were collected from each 20 piglet out of 26-32 days old before vaccination, and then from the 14th and 28th day post-vaccination(PV) with LOM live virus vaccine at the J and C swine ranches in the suburbs of Chonju. Monoclonal antibody(MAb) against ALD strain of hog cholera virus(HCV) and goal antimouse FITC-conjugates were employed in indirect immunofluorescence(IF) test for the titration of HCV and neuralization IF test for serum neutralization(SN)-Ab-titers against HCV. SN-Ab-titers(M±S.D.) were <2±0 in all piglets before vaccination at the both swine ranches. Whereas SN-Ab-titers of the J and C swine ranches were 111.2±115.08 and 144±121.7 at the 14th day PV and were 361.6±279.6 and 723.2±966.2 at the 28th day PV, respectively. Compared with Duncan's test, SN-Ab-titers were not significantl difference between the H and C swine ranches of the 14th day PV, but were significantly difference at the 28th day PV (P<0.0009). Therefore, SN-Ab-titers were significantly difference between the 14th and 28th day at the J or C ranches, respectively(P<0.0007, P<0.0114). Excepting SN-Ab-titer was1:16 in one piglet of the 14th day PV at the J swine ranch, defensible levels of SN-Ab-titers could be detected in all piglets PV of the both swine ranches. It is suggested that varied dffect of vaccination against HCV may be depended by feed and mangement, enviroment, sanitary conditions, breed and pedigree or vaccination program, etc.

To investigate the effects of conjugated linoleic acid added diet feeding on CLA accumulation and quality characteristics of port meat. The CLA used to add in diet was chemically synthesized by alkaline isomerization method with com oil. Pigs were divided into 5 treatment groups(4 pigs/group) and subjected to one of five treatment diets(0, 1.25% CLA for 2 weeks, 2.5% CLA for 2 weeks, 1.25% CLA for 4 weeks and 2.5% CLA for 4 weeks, CLA diets; total fed diets) before slaughter. Pork loin were collected from the animals(110㎏ body weight) slaughtering at the commercial slaughter house. Pork loin meat were aerobic packaged and then stored during 2, 5, 8, 11 and 14 days at 4℃. Samples were analyzed for shear force value, texture, TBARS, fatty acid composition, cholestreol and CLA content. CLA treatment groups showed significantly(p<0.05) higher shear force value compared to those of control group at 11, 14 days of cold storage. All treatments were decreased significantly as the storage period passed. There was a not significantly difference in texture between control and CLA treatment groups. All CLA treatment groups showed significantly(p<0.05) lower TBARS value than the control. TBARS value was increased significantly during storage in all treatment. CLA treatment groups showed significantly(p<0.05) lower cholesterol content compared to those of control group. As dietary CLA was increased in feed, the content of CLA was increased, but the control was almost not detected. The contents of CLA were not significantly changed during chilled storage for 14 days. In the change of fatty acid composition, the contents of oleic, linoleic and arachidonic were decreased by dietary CLA-supplementation, whereas the increase level of CLA-supplementation resulted in the higher palmitic and stearic acid. In all results, CLA could be accumulated in pork meat and its antioxidant capability had been indicated. It was suggested that dietary CLA-supplementation could be produced high quality pork.

It is hard to collect sufficient speech data for training a speaker-dependent (SD) model from the same speaker. In contrast, to trains a speaker-independent (SI) model need not collect a large amount of speech data per speaker but from many speakers. Speaker-adaptation (SA) is an additional training technique from SI model by a small amount of adaptation speech. It has proved to be a powerful tool for achieving good recognition performance without the high cost of SD training. In this study, a speaker adaptation algorithm (MAPE) which trains it by every utterance sequentially without hand-labelling is introduces. The hand-labelling is performed automatically by Concatenation training and Viterbi-segmentation. The secuential-training is performed by MAPE(Maximum A Posteriori probability Estimation). We can train it using any small amount of adaptation speech data. For newspaper editorial continuous speech, the recognition rates of adaptation of HMM was 62.5% respectively which is approximately 32.5% improvement over that of unadapated HMM.

In a trial involving 120 pigs, the effects of transport time on blood profile and meat quality in pigs were investigated. One group of 60 animals was subjected to 20min and the others to 2 h transport time, and held in lairage for 1 h 30min. There was not significantly different in the carcass weight, backfat thickness and carcass grade between groups. Cortisol and lactic dehydrogenase(LDH) concentrations were significantly(P<0.05) higher in the group transported for 2 h compared with the group transported for 20min. There was not significantly different(P>0.05) in meat quality(?_(1), ?_(u), drip loss, cooking loss, hardness, CIE L^(*), a^(*), b^9*) and NPPC) and skin damage of port carcass between groups. These results imply that the stress could be affected by transport time in transit without meat quality.

A conventional CHMM is unable to express time transient variation well. In this paper, we formed segments to combine several frames and made up a vector for each segment to reflect a dynamic variation speech. If we used as they were, the number of parameter's dimensions increased. Therefore we could not estimate aptly when the train date was insufficient. So we compressed the parameter's dimensions and decreased the number of parameter's dimensions. At the exteriment, we compared the result of using vectors compressing mel-cepstrum by the K-L transformation with the result of using mel-cepstrum and mel-cepstrum coefficients. At the result, we got higher recognition rates of using mel-cepstrum and mel-cepstrum + regressive coefficients than that of using vectors compressing mel-cepstrum by the K-L transformation.
