The object of this study was to estimate the heritabilities, phenotypic and genetic correlations among certain body measurements in Korean Native Cattle. The experimental animals for this study were 248 heads of Korean Native Cattle from 49 sires born from 1971 to 1982 at the Alpine Experiment Station in Pyung-Chang, Korea. The traits included in this study were withers height, chest width, chest girth, body length and thud width at 6 month and 12 month of age, The results obtained are summarized as follows; 1. The heritability estimates obtained in this study were 0.19 and 0.21 for withers height at 6 and 12 month, 0.15 and 0.45 for chest width at 6 and 12 month, 0.27 and 0.61 for chest girth at 6 and 12 month, 0.14 and 0.50 for body length at 6 and 12 month, 0.27 and 0.67 for thud width at 6 and 12 month. 2. The ranges of genetic, environmental and phenotypic correlations among body measurements at 6 month of age were 0.31-0.98, 0.33-0.65 and 0.39-0.64, respectively. The ranges of correlations among body measurements at 12 month of age were 0.62-1.09, 0.52-0.45 and 0.32-0.54, respectively. 3. The heritability estimates for 6-month body measurements were lower than for 12-month body measurements. The genetic correlations among body measurements at 6 or 12 month of age were high and positive, while the genetic correlations between body measurements at 6 and 12 month of age have shown much variation depending on the combinations of the traits.

The object of this study was to estimate the heritabilities, phenotypic and genetic correlations among average daily gain, DCP consumed per unit gain and TDN consumed per unit gain in Korean Native Cattle. The experimental animals for this study were 248 heads of Korean Native bulls from 49 sires born from February, 1971 to January, 1983 at the Alpine Experiment Station at Pyung-chang, Korea. Calves were weaned at about six month of age. The traits included in this study were postweaning average daily again, DCP consumed per unit gain and TDN consumed per unit gain. The results obtained are summarized as follows; 1. The effect of season of birth was significant for DCP and TDN consumed per unit weight gain. The effect of age of dam was significant for average daily gain. 2. The heritability estimate of postweaning performance traits was 0.73±0.24 for average daily gain, 0.62±0.23 for DCP consumed per unit gain and 0.471±0.21 for TDN consumed per unit gain. 3. The genetic correlations of average daily gain with DCP and TDN consumed per unit gain were -0.96 and -0.78, respectively, and phenotypic correlations were -0.53 and -0.49 and environmental correlations were 0.36 and -0.08. The genetic, phenotypic and environmental correlations between DCP consumed per unit gain and TDN consumed per unit gain were 0.78, 0.91 and 1.08, respectively.

This paper proposes LM method for solving bin-picking problem in robot vision. It has the processing steps such as image enchancement, image thresholding, region labelling, and moment computation. To determine a target object from bined objects, the modified labelling method is used. To determine position and orientation of holdsite, the moment method is used. Finally, some experiment results are illustated and compared with the results of conventional shrinking algorithm. The proposed LM method has reduced processing time.

This study was carried out to investigate the specimen in martensite structure added Mo and not added Mo on the aging treatment were generated each changes of microstructure and mechanical properties, the result obtained from this study are as follow: In case of specimen added Mo, A Laves phase was mainly precipitated in ferrite phase, while carbide and Laves phase were overlapping precipitated in martensite phase, on the interface of martensite and ferrite phase. In case of specimen not add Mo, A microstructure was unchanged in ferrite phase, while carbide was precipitated in martensite phase. In case of specimen added Mo, A ferrite hardness change existed two peaks with the increase of the aging time, while a martensite hardness change which a hardness in the early stage of aging was low, but a re-hardening was occurred with the increase of the aging time. In case of specimen not add Mo, While a ferrite hardness change of aging was not largely changed, a ferrite hardness change was sharply decreased in the early stage of aging, but it was slowly decreased with the increase of the aging time. The tensile strength of specimen added Mo was eventually decreased with the increase of the aging time, while the tensile strength of specimen not added Mo was slowly decreased. A Sharpy impact's value of specimen added Mo was largely decreased by the aging treatment, while it was slowly increased with the increase of the aging time, in case of specimen not add Mo was gradually increased in the early stage of aging, the aging time was long, then it was quickly increased. The Disk shape of Laves phase precipitation in the early stage of aging was largely decreased the impact toughness .
