Objective: Several studies have reported the development of new molecular methods for the prognosis and diagnosis of male fertility based on biomarkers aimed at overcoming the limitations of conventional male fertility analysis tools. However, further studies are needed for the field application of these methods. Therefore, alternative methods based on existing semen analysis methods are required to improve production efficiency in the animal industry. Methods: we examined the possibility of improving litter size in various pig breeds using combined Hoechst 33258/chlortetracycline fluorescence (H33258/CTC) staining. The correlation between field fertility and capacitation status by combined H33258/CTC staining in different ejaculates spermatozoa (n = 3) from an individual boar (20 Landrace, 20 Yorkshire, and 20 Duroc) was evaluated as well as overall accuracy. Results: The acrosome reacted (AR) pattern after capacitation (%) was positively correlated with the litter size of Landrace, Yorkshire, and Duroc pigs and the overall accuracy was 75%, 75%, and 70% in Landrace, Yorkshire, and Duroc pigs, respectively. The difference (${\Delta}$) in AR pattern before and after capacitation was positively correlated with the litter size of Landrace, Yorkshire, and Duroc pigs and the overall accuracy was 80%, 65%, and 55% in Landrace, Yorkshire, and Duroc pigs, respectively. However, the difference (${\Delta}$) in capacitated (B) pattern before and after capacitation was negatively correlated with the litter size of Landrace pigs and the overall accuracy was 75%. Moreover, average litter size was significantly altered according to different combined H33258/CTC staining parameters. Conclusion: These results show that combined H33258/CTC staining may be used to predict male fertility in various breeds. However, the selection of specific efficiency combined H33258/CTC staining parameters requires further consideration. Taken together, these findings suggest that combined H33258/CTC staining may constitute an alternative method for predicting male fertility until such time as fertility-related biomarkers are further validated.

The purpose of this study is to develop brassiere patterns which are both fitting and functional for women aged 19 to 24(the 1924 generation). We suggested a 'size chart for body measurements' for constructing basic brassiere patterns with six sizes of '70, 75', 'AA, A, B cups', which are used most frequently by the 1924 generation consumers. The scope of research was in reference to the statistical analysis results of the Size Korea(2004) body measurements and the results of the data from the preceding research. The 'drafting method for constructing basic brassiere patterns for the 1924 generation consumers' was completed by selecting a total of 18 subjects, 3 for each six sizes in the scope of research, and three wearing tests were carried out with the subjects. We compiled one brassiere pattern in six sizes obtained with the drafting method of constructing a basic brassiere pattern on another by block pattern in order to observe the phase of change in dimensions and shapes of paper pattern. The result was converted into the variations of a x-axis and a y-axis, and we suggested 'Size Grading Rule' and 'Cup Grading Rule' for the basic brassiere patterns. As the results of the wearing evaluation of the basic brassieres and measuring the variation in body dimensions by wearing brassieres, the dimensions and shapes of the basic brassieres suggested in this research proved to be fitting and to have a wearing effect that brings together and supports the breasts.

This study were to grasp the present situation of the pet wear market and the problem of pet wear, and to develop the pet wear pattern which agrees well to dog's shape and movements. We carried out survey research to analyze the actual pet wear market condition for a dog-lover, and movement analysis and sensory test to develop a pattern for Maltese which was the favorite dog among Korean. For data analysis, ANOVA with duncan test, T-test were conducted using SPSS statistic program(ver. 10.0). The results are as follows: 1. The results of the survey research, 75% of dog-lover had a pet wear and favorite was T-shirts. The problems of wearing T-shirts were 'too tight seam sleeve and bodice(front legs hole)', 'the clothes easily hang down' and 'easily taken off due to large neck size'. 2. The ease amount of the developed pattern was given according to the results of dog's shape and movement analysis, and the results of sensory test, there is a significant difference in the following items: depth of front neck line, front chest${\to}$abdomen curve, ease amount of sleeve, comfort level of leg parts. 3. The size of each parts of the developed pattern in this study were as follows : neck girth 27.0cm, body girth 40.0cm, back length 26.0cm, front leg girth 23.0cm, sleeve length 20.7cm, sleeve width 14.4cm. But, there exists some limits to generalize these results since dog's body size and shapes are various according to dog species. Therefore, further studies are needed to develop each pet wear pattern for each dog species.

The purpose of this study was to establish a sizing system according to size and dimension whereby manufactured pants can be classified and develop men’s formal pants pattern based on the analysis of ready-made and educational pants pattern. The first, we surveyed the sizing and the basic pants patterns of the men’s ready-made wear companies, Secondly, through the survey data of the domestic men’ready-mad clothing industry, we proposed a new sizing system. Lastly, after compared three different types of ready-mad pants manufactured according to their patterns and an additional type of pants made after the educational pattern, the new men’s basic pants pattern were developed. The findings were as follows: 1. Survey of the domestic ready-mad garment industry showed that each company classified its own manufactured goods according to its own sizing system: moreover, they each used its own unique patterns which appeared to be resulted from a combination of two factors : the experience of a patterner and foreign know-how technology. 2. New sizing system was developed with 12 steps from size 74-88 to size 96-106 based on the high frequencies of the companies’3. New basic patterns for men’s formal pants were developed: Inseam length = 80cm, crotch line = H/4+4.6cm, pants ham = 23.5cm as basic lines and front waist girth =W/4+9.1cm as drafting line. 4. the superiority of the new basic patterns were been demonstrated by a high approval rate of the subjects who participated in testing.

In the present study, a new pattern recognition algorithm was proposed to size spray particles using the boundary curvature information. Conceptually, this algorithm has an advantage over the others because it can identify the particle size and shape simultaneously, and also can separate the overlapped particles more effectively. Curvature of a boundary was obtained from the change of the slopes of two neighboring segments at the corresponding part. The algorithm developed in this study was tested by using an artificially prepared image of a group of spherical particles which were either isolated or overlapped. Particle sizes obtained from the measured curvatures agreed well with the true values. By detecting abrupt changes of the curvature along the image boundary, the element particles could be separated out from their overlapped images successfully.

The flow fields in the volute casing of a small-size turbo-compressor at different flowrate (design point ${\pm}20%$) are studied by numerical analysis. The governing equations for three-dimensional steady viscous flow are solved using SIMPLE algorithm with commercial code of STAR-CD. Numerical results show that the three-dimensional flow pattern inside the volute casing of a small-size turbo-compressor is strongly influenced by secondary flows that are typically created by the curvature or the casing passages. The flow pattern in the casing also affects the performance of the turbo-compressor. In order to elucidate the loss mechanism through the volute, we prepared the secondary flow, velocity magnitude, and static pressure distribution at the four cross-sectional planes of the casing.

The suitability of the pattern manufactured with the development figure was considered by reviewing the development conditions that can be directly connected to the basic pattern in the human body surface development figure with the cast bandage method. The method to prepare the sleeve basic pattern was based on the cylindrical surface development method, and the sleeve basic pattern covering the 45 and 90 degrees momentum of the arm-movement was made by using the cast-type body surface development figure prepared with the horizontal line of the sleeve hem placed horizontally in the plan and by combining the cast-type body surface development figure in the standing position with the figure in the moving position. The test clothing was prepared with the sleeve pattern adding the bodice pattern in the standing position and the momentum and was worn on the FRP replica. The relationship theory of the body surface development figure with the pattern was derived by reviewing the suitability from the wearing state. The sleeve-cap height of the sleeve basic pattern resulted in about 80% in the standing position when the needs for a physical activity are 45 degrees and the about 50% when the needs for a physical activity are 90 degrees. The additional size of the diagonal length of the sleeve-cap could be set as "0" if the sleeve-cap height is low by 50% and as 50% of the additional size in the standing position if the sleeve-cap height is 80%.

We have analyzed the output characteristics of a LGP with pyramid shaped pattern by using a 3-D simulation tool. The influences on the LGP output of various parameters such as the pattern shape, pattern occupation ratio, pattern size, and etching angle were investigated. Comparing the pyramid shaped pattern with hemispherical patterns, little difference was observed. And, it was proved that the pattern occupation ratio and etching angle have relatively large effects on LGP output characteristics, while the pattern size has no effect. Therefore, we can improve the LGP characteristics by optimizing pattern structure and distribution.
