This study utilized 10,502 linear type scores collected by KAIA from 1984 to 1993 with records consisting of 15 primary traits and final score. The results obtained were as follows ; 1. Rump width scores were positively correlated with parity and age but udder support scores were negatively correlated with them. 2. Among the age and lactation groups, the over-3rd parity group had tower fore-udder attachment scores than the 1 st or 2nd parity groups. 3. A multiplicative adjustment factor was more suitable for adjusting type scores than additive adjustment factor. 4. It was suggested that establishment of a base score is necessary to develop adjustment factors for each type trait.

This study was undertaken to identify the changes of variance components for herd production levels of milk. Milk records were divided into low, medium, and high groups by average herd production, average herd-year production, herd standard deviation, and herd-year standard deviation. Herd standard deviations increased with average herd productions. Correlation between average herd production and herd standard deviation was 0.41, while correlation between average herd-year production and herd-year standard deviation was 0.47. Residual variance components of higher production increased remarkably, while genetic variance components of high group by herd-year standard deviation showed the same increasing trend. When records are transformed to logarithms, however, residual components of variance didn`t show the increasing trend, and the changing ratio decreased markedly without homogeneous variance components. In order to account for the heterogeneity of milk among herds, the optimum classifying criterion was an average herd-year production level. Estimates of heritabilities for low, medium and high groups were 0.185, 0.237, and 0.283, respectively. These results remarkably showed the heterogeneity of milk among dairy herds.

Three thousand two hundred twenty-one linear type records, 3,298 production records and 1,652 type-production records of Holsteins in Korea collected from 1984 to 1994 by the KAIA (Korea Animal Improvement Association) were analyzed to estimate genetic parameters as well as genetic and phenotypic correlations among type and production traits using multivariate REML. The heritabilities for milk and fat yield adjusted to 305 days were 0.31±0.07 and 0.26±0.06, respectively. The genetic correlation between milk and fat yields was 0.82 and the phenotypic correlation was 0.75. Linear type scores were low, especially for udder traits. The heritabilities for type traits ranged from 0.10 for udder support to 0.54 for stature. Rear udder height had the highest positive genetic correlation with rear udder width(0.72), whereas foot angle had the highest negative genetic correlation with rear legs side view(-0.36). Angularity, foot angle, rear udder width and teat placement had high genetic correlations with milk yield(0.31, 0.41 and -0.32, respectively). Rump angle, foot angle and rear udder width had high genetic correlations with fat yield(-0.37, -0.50 and 0.39, respectively).
Development of a Deep Learning-based Electronic Nose System for Real-time Gas Identification

The demand for gas sensors is increasing because of the growing interest in monitoring indoor/outdoor air pollutions. In particular, small-sized, low-cost, and highly sensitive semiconductor metal oxide (SMO) gas sensors are attracting attention as the next-generation gas sensors. However, there are limitations in the actual applications of SMO gas sensors due to their low selectivity. Although the method of implementing gas identification through multi-sensor-based electronic nose systems is in the limelight, the problems that it is difficult to implement gas identification in real-time, have yet to be resolved. In this study, the selectivity problem could be solved by fabricating a gas sensor array and applying the sensing data from the sensor array to the deep learning network. The fabricated gas sensor array used nanocolumnar films of metal oxides (SnO₂, In₂O₃, WO₃, and CuO) deposited through the glancing angle deposition (GLAD) as the sensing materials, and the convolutional neural network (CNN) was selected as the deep learning network for gas identification. Finally, a real-time gas identification for CO, NH₃, NO₂, Methane, and Acetone gas was achieved with an accuracy of 98% by applying preprocessed sensing data collected from the gas sensor arrays to the CNN.
