Damages that develop in structural elements decrease the structural integrity of the structure and finally results in early failure of the structure. Therefore, the earlier the damages in the structure are detected and repaired, the longer the service life of the structure results. Monitoring the formation and the development of the structural damages in structural elements will help evaluating the structural integrity which determines the load carrying capacity and the remaining life of the whole structure. The best way of detecting damages in existing structure is using nondestructive tests considering that it is practically impossible to sample cores all over the structure. In this research, the stress waves, especially the surface waves, were used to evaluate the cracks in concrete slabs. For crack detection, one concrete slab with different depths of cracks were fabricated. The cracks were created on the surface of the concrete slab. The effect of the cracks on the stress wave propagation was investigated by measuring phase velocity and attenuation ratio of the frequency magnitude plot. The results show a good agreement between the test results and the actual damage condition

This study was conducted to investigate the differences of measurement methods on carcass traits with 160 hogs. The carcass traits were measured by Destron Pork Grader-100 (PG), Danish Fat-0-Meat`er (FOM) and manual method and the summarized results are as follows; 1. Ranges of retail cuts and trimmed fat percentage were 62.1 to 78.3% and 7.2 to 22.7%. 2. On the 3-4th lumbar vertebrae and last rib, backfat thickness was significantly different by each method (p$lt;0.01). 3. On the 11-12th ribs, backfat thickness was not significantly different between PG and FOM but different between manual method and FOM (p$lt;0.01). 4. The simple correlations between retail cuts and backfat thickness, carcass weight, carcass length and muscle depth were -0.43 to -0.68, -0.21 to -0.23, -0.19 and 0.08 to 0.18, respectively. 5. The measurement of grading machines showed higher correlations with retail cuts percent than manual method and backfat thickness of FOM showed higher than that of PG at 3-4th lumbar vertebrae but not different between FOM and PG at other sites. 6. Conclusively, it is desired that the different estimating equations are used for more accuracy estimate of meat productivity.

Increase in daily protein consumption per capita from 1975(85.1 g) to 2001(88.4 g) was 3.3 g. This trend was relatively slower than the case of Japan where daily protein consumption was 84.7 g in 1975 and 90.3 g in 2001. Animal-related protein in 2003 was 45.7 g in which 61% was originated from meat, milk and egg whereas 39% was composed of fish and its relevance. The trend of protein consumption fairly come up with the ideal ratio of 5:5 between animal-originated protein and plant-originated protein, following the base case of Japan. The effect of animal protein on human health can vary depending on one"s viewpoint and its controversy is still a subject of debate. For the reason, two faces of positive and negative effects on human health coexists. However, there is no doubt that positive effect is far more than negative one. It is not important whether or not animal protein is more beneficial for human health. However, it is more important how human balance between two proteins.

This study was conducted to determine the estimating equations for retail cuts percentage of pork carcass by grading machines and manual measurement with 160 hogs. Carcass grading machines used were Destron Pork grader-100(PG) and Danish Fat-O-Meat`er(FOM), and the summarized results are as follows; l. The carcass weight and carcass length showed negative correlation(r=-0.23, -0.19, respectively) with retail cuts percentage. 2. Among average of two site measurements, the average of backfat thickness at 11-12th ribs and last ribs showed the highest correlation with retail cuts percentage. 3. Average of three site measurements showed lower correlation with retail cuts percentage than average of two site measurements. 4. Conclusively, the estimating equations for retail cuts percentage by measurement methods were Y=77.60-0.003(Hot carcass weight) -4.46(Backfat thickness) for Handling, Y=73.97+0.011(Hot carcass weight) -0.60(Backfat thickness) +0.09(Muscle depth) for PG and Y=74.58+0.022(Hot carcass weight)-0.69(Backfat thickness) +0.07(Muscle depth) for FOM, respectively.
