The purpose of this study was to examine the inconvenience when putting on stretchable pants and to analyze the whole actual conditions of making of the lining fabrics. For this study, we conducted a survey of women in their twenties and collected the basic data and master pattern through material of a woman's wear brand and the interview and questionnaires. The results of this study were as follows. First, the survey result for the woman consumers it showed that the most uncomfortable problem about the lining of pants was not sufficient stretch as much as the out-shell. Secondly, it was shown that many brands(46.7%) were using the lining fabrics of stretch clothes mixed with 'non-stretch fabrics' and 'stretch fabrics'. The result of lining pattern making for the stretch pants showed that the ease of the lining fabrics was 0 to 4cm in the hip girth more than out-shell. The ease in crotch width was 0 to 1.3cm for lining fabrics. But in the stretch lining fabrics the ease for front crotch width was 0 to 1cm more than out-shell. The lengths of crotch rising were -0.7 to 1.3cm for the non-stretch lining fabrics and -1 to 1cm for the stretch lining fabrics.

The purpose of this study is to analyze present the pattern making of the lining fabrics calculating the right ease and rising quantities of arm-hole when the pattern of the lining fabrics of stretchable jacket fabrics is produced. The outcomes of this study are as follows. The right ease of lining fabrics was not room of 0cm as patterns being same the right side of fabrics in the girth of the chest, waist, and the edge of a garment and gets the most excellent valuation, and then the girth of the chest, and waist was applied to 2cm and around the edge of a garment 0cm in regular lining fabrics. In addition to, although the ease of patterns of the lining fabrics was more, it was not necessarily to satisfy. The result of the valuation according to the quantities of rising arm-hole of the pattern of the lining fabrics showed that the making lining fabrics that the quantities of rising arm-hole was 0.8cm in the body and 1.2cm in the sleeve in the both the stretchable fabrics and regular lining fabrics was the most excellent thing, and then 0cm in the body and 2cm in the sleeve, and then 0cm in the body and 0cm in the sleeve. The valuation of external appearance on the quantities of rising arm-hole was recognized similarly because of being rarely significance level, but around the chest and waist was recognized as being significance level in wearing satisfaction.

The purpose of this study is to analyze the ease of stretchable jackets which has been common since the mid-1990s and the whole actual conditions in making the lining fabrics. This can be done by investigating the actual conditions of domestic clothes businesses about the consumers. The outcomes of this study are as follows; The result of the survey in the differences of the ease between regular and stretchable fabrics shows that the pattern of designing stretchable fabrics needs diminishing the width of shoulder is 0.42cm, the whole girth chest is 1.83cm, the whole girth of waist is 0.88cm. It also shows that designing the ease of the whole girth of chest is 1.91cm to 2.54cm in the regular lining fabrics and is from 0 to 1.27cm in the stretchable fabrics more than the right side of fabrics. The ease of the whole girth of waist is similar to the round chest, in which the bottom sweep for garment is almost equal to the right side of fabrics in both regular lining fabrics and stretchable fabrics. The result of investigating the actual conditions of making the lining fabrics of stretchable jacket fabrics shows that 80% of a woman's wear brand produces and gives the pattern of the lining fabrics only for the special designing to the cooperative clothes manufactures. The business which always provides the patterns for the lining fabrics in the main office is only limited to 20%. Also, it shows that using the lining fabrics of stretchable jacket fabrics and regular lining fabrics together is 46.7%, the stretchable lining fabrics is 40% and the regular lining fabrics is 13.3% only.

This study seeks to offer practical suggestions for manufacturing jacket lining patterns through research on menswear brands. A researcher conducted interviews with a survey instrument targeting 12 menswear brands. To analyze the data, descriptive statistics were obtained using SPSS 18.0. The main findings were as follows. First, regarding lining production, most menswear brands were found to provide jacket lining patterns to their subcontractors, and pattern makers were found to design lining patterns based on their own know-how. The most important factor in the production of jacket lining patterns is whether linings are cut more than once during the sewing process. For suit jackets, linings are cut more than once, and for casual jackets, linings are cut once. Second, with regard to jacket production for different jacket styles, most menswear brands were found to use patterns that include seam allowance. Partial linings showed differences in terms of the methods used to sew edges and attach linings to the outer shell. Third, extra space in jacket lining patterns varied according to style. Jacket lining patterns for suit jackets and casual jackets showed differences in extra space in the following areas: the parts that cover the chest(suit jacket linings: 5.6cm, casual jacket linings: 2.4cm), the parts that cover the waist(suit jacket linings: 3.8cm, casual jacket linings: 1.3cm), hem(suit jacket linings: 2.7cm, casual jacket linings: 1.3cm), and bicep(suit jacket linings: 2.7cm, casual jacket linings: 1.1cm). However, extra space in the sleeve hems was identical for the two styles(suit jacket linings: 0.1cm, casual jacket linings: 0.1cm). Therefore, this research suggests that clothing manufacturers design linings in accordance with the jacket lining production style.

Numerical simulation is conducted to clarify the heat transfer and fluid flow characteristics of brake disk-lining for rolling stock. Multiple rotational reference frame, k-epsilon turbulent model and SIMPLE algorithm based on finite volume method are used to solve the physical disk-lining model. The governing equations are solved by TDMA(TriDiagonal Matrix Algorithm) with line-by-line method and block correction, From the results of simulation, the characteristics of cooling pattern is strongly affected by the grooves in lining. The face lift of lining affects on the temperature distribution of rear surface of lining as well as the front surface of that. Due to the grooves in lining, it will be expected to extend the maintenance life circle of lining.

This research aimed for 20 latter man whose body shape of torso alters remarkably to develop nipper pattern of running type considered characteristic of body shape of 20 latter man to keep rather balanced body shape against middle age when body shape changes extremely. 1. running type nipper pattern design. Pattern of running, lining and nipper were designed by flattening surface shell. A basis line of running pattern is completed by applying reduction ratio after 3 times of modification & complement based on surface shell. Nipper pattern is designed with design line set by a plaster cast based on running pattern line. Lining pattern is designed with lining design line set by a plaster cast based on running type outside material and nipper pattern. 2. Functional evaluation of research and commercial nipper. Functional inspection through dress test was applied 5point evaluation method and the result of functional inspection on the sight of a wearer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged more 4.8point but commercial nipper averaged less 1.8point in the aspect of 20 items such as wear sensibility, motional function and external appearance aesthetic. Research running type nipper scored high in order of motional function, looks of side, back, front and whole and wear sensibility. Functional inspection in the point of view of an observer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged over 4.8point and commercial nipper averaged under 1.9point in 17 items of external appearance beauty. Research running type nipper marked high in order of looks of back, whole, front and side.

Subway tunnel structure has been rapidly developed in many cities for its strong transport capacity. The model-based damage detection of subway tunnel structure is usually difficult due to the complex modeling of soil-structure interaction, the indetermination of boundary and so on. This paper proposes a new data-based method for the damage detection of subway tunnel structure. The root mean square acceleration and cross correlation function are used to derive a statistical pattern recognition algorithm for damage detection. A damage sensitive feature is proposed based on the root mean square deviations of the cross correlation functions. X-bar control charts are utilized to monitor the variation of the damage sensitive features before and after damage. The proposed algorithm is validated by the experiment of a full-scale two-rings subway tunnel lining, and damages are simulated by loosening the connection bolts of the rings. The results verify that root mean square deviation is sensitive to bolt loosening in the tunnel lining and X-bar control charts are feasible to be used in damage detection. The proposed data-based damage detection method is applicable to the online structural health monitoring system of subway tunnel lining.

We use investment to retain the mould of the wax pattern in making dental metal castings. A fin on the metal casting is occasionally formed due to several factors. The factors making the fin are improper burn out time and temperature, improper W/P ratio of investment and lining of asbestos in casting ring. The purpose of this study is to investigate the effect of W/P ratio of investment on the fin formation. Except the W/P ratio of investment which used to invest the wax pattern, the study was done under same condition; burn out time and temperature, W/P ratio of refractory cast(W/P=0.12) and asbestos lining in casting ring. The obtained result is that the fin is more likely to be formed on the casting which invested with higher W/P ratio of investment to that of refractory cast.
