The purpose of this study is to find the proper width of fabric which can bring high efficiency on productivity. We focus on the marking method by comparing and analyzing the marking efficiency of flare skirt. This study employs 4 criteria to mark the flare skirt, which are angle, location, width, and direction, respectively. There can be 3 different angles$(180^{\circ},\;270^{\circ},\;360^{\circ})$, and 2 different locations(the center line and the middle of the pattern) according to fixing of the warp line of the fabric. Also, width can be classified into 2 groups(110cm, 150cm), and marking direction can be grouped into 2(one direction marker and one direction per each size marker). These 4 criteria make $24(3{\times}2{\times}2{\times}2)$ cases for this study. Main findings are follows. Fist, the skirt with the 150cm width has higher efficiency rate than that of 110cm. Second, fixing the warp line at the center line has higher efficiency rate than that in the middle. Finally, per size marker has much higher efficiency than the just direction marker. In sum, we find that 150cm width with the center warp line and per size marker brings the highest efficiency rate.

Comparative analysis of marker efficiency in blouse patterns, based on different sleeve designs, was carried out. Sleeve designs used included set-in-sleeve, laglan sleeve, and epaulet sleeve. The two types of epaulet sleeves, A and B, are based on pattern arrangement methods of center back. Cloth and production conditions are the width of cloth, the number of marking pieces, and the direction for marking deployment. A blouse pattern saved to the PAD CAD System was graded with different sizes and arranged for industrial purpose to calculate the marker efficiency in different conditions. The results were as follows. On the whole, the marker efficiency of small pattern sized set-insleeve was higher than laglan and epaulet sleeve designs. It was also established that marker efficiency is dependent on cloth and production conditions. For small number of marking pieces, efficiency was higher in the condition of 110cm cloth widths compared with that condition of 150cm cloth widths. However the efficiency of large number of marking pieces was higher in the condition of 150cm cloth widths.

This study intended to compare and analyze marking efficiencies of basic slacks, based on different cloth and production conditions, the width of cloth, the number of marking pieces and the direction for marking deployment and proposed an efficient marking method. The results were as follows. On the whole, the marking efficiencies increased with increasing cloth widths. In the case of small number of marking pieces, the efficiency increased with increasing cloth widths, while, for large number of marking pieces, there was no differences in the efficiency with the cloth widths. From the result of the comparison of the marking efficiencies with the number of marking pieces, it was shown that, in the case of small cloth width, the efficiency increased considerably with increasing number of marking pieces, while, in the case of large cloth width over two markers, there was no distinct effect of the number of markers on the marking efficiency. Thought there were some differences of the marking efficiencies with the marker directions, bi-direction marker was the most efficient marker, followed by one-direction for each size marker and one-direction marker.

The purpose of this study is to find the proper width of fabric which can bring high efficiency on productivity. We focus on the marking method by comparing and analyzing the marking efficiency of A-line skirt. This study employs 4 criteria to mark the A-line skirt, which are cutting method, angle, width, and direction, respectively. There can be 2 different cutting methods(fold pattern and add seam pattern at the front and back center line), and 2 different angles(warp angle and bias angle). Also, width of the fabric can be classified into 2 groups(110cm, 150cm), and marking direction can be grouped into 2(one direction marker and one direction per each size marker). These 4 criteria make 16($2^*2^*2^*2$) cases for this study. Main findings are follows. First, the skirt with folded at the center line had higher efficiency rate than the skirt with add seam at the center line. Second, the skirt with the 150cm width has higher efficiency rate than that of 110cm. Third, fixing the warp angle has higher efficiency rate than that of fixing the bias angle at the front and back center line. Finally, one direction per each size marker has much higher efficiency than the one direction marker.

This study intended to compare and analyze marking efficiencies of tailored jacket based on different cloth and production conditions, 'the width of cloth', 'the number of marking pieces' and 'the direction for marking deployment'. The results were as follows. For the two pieces of markers, the efficiency of the cloth width of 110cm was higher than that of 150cm. As the number of markers increased, the efficiency of cloth width of 150cm was higher than that of 110cm. In the case of one-directional deployment, the results obtained was that the efficiency of two markers was higher than that of three markers, while, in the case of bi-directional deployment, the efficiency of three markers was higher than that of two markers. In the case of one-directional deployment for each size, the marking efficiencies were higher in two markers at the cloth width of 110 cm and higher in three markers at the cloth width of 150 cm. Then, in marking efficiencies according to the direction for marking deployment, bi-direction marker was the most efficient marker, followed by one-direction for each size marker and one-direction marker.

Genomics research has two ultimate applied goals: to Isolate and clone genes of economic importance for bio-technology and gene-assisted selection (GAS), and to locate and use markers for marker-assisted selection (MAS) in selective breeding programs. To this end, we have identified linked markers for feed conversion efficiency growth rate, and disease resistance to enteric septicemia of catfish (ESC). Three microsatellite markers Ip266, Ip384, and Ip607 were identified to be linked to feed conversion efficiency. Similarly one marker each was identified to be linked to growth rate (Ip607) and disease resistance to ESC (Ip477). Ip607 marker linked to both growth rate and feed conversion efficiency, indicating that the QTL for both growth rate and feed conversion efficiency may either be the same or located in the same chromosomal region in the catfish genome. On phenotypic evaluation, certain traits such as growth rate can be accurately evaluated by body weight evaluation while other traits such as disease resistance can be quite complex. The linked DNA markers will be highly useful for MAS programs and for directing further efforts of genomic mapping for important quantitative traits.

The efficiency of marker assisted selection(MAS) over conventional selection index based sorely on phenotypic records was studied by deterministic simulation model. Parameter combination of heritability and amount of genetic variation due to the markers included in the index was employed. For the index with own phenotypic information vs. the index with own phenotypic plus marker information, the relative efficiency of MAS over the selection with phenotypic records was about 38% high when heritability was low(0.05). However, when heritability was high(50%), the relative efficiency of MAS was vary low and almost negligible. For more practical situation of selection index which included information on own, sire and dam, MAS was less effective than when selection criteria was only on own performance.

This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern, width of materials, and marker orientation using man's shirts. To compare the marking efficiency of shirts, plain and check-patterned materials with the intervals of $1.5{\times}1.5cm$, $3{\times}3cm$, and $5{\times}5cm$ were selected. First, in the comparison of marking efficiency depending on materials width, the highest efficiency was obtained with nap-either-way position of 150cm, plain materials and lowest efficiency with nap-one-way position of 150cm, $5{\times}5cm$ check-pattern materials. Regardless of the direction of marker position, the marking efficiency of 150cm width was higher than 110cm width in the plain, $1.5{\times}1.5cm$ and $3{\times}3cm$ check-pattern interval, but the marking efficiency of 110cm width was higher than 150cm width in the $1.5{\times}1.5cm$ check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and material width, the highest efficiency was obtained with nap-either-way position. And nap-up-and-down and nap-one-way follows next. Third, in the comparison of marking efficiency depending on check-pattern interval, the efficiency of plain materials was higher than those of check-patterned materials. And increasing the intervals decreased marking efficiency and vice versa. So the lowest efficiency was obtained with $5{\times}5cm$ check patterned materials.
