The purpose of this thesis was to develop torso patterns according to the physical types of men in 20s. The procedure and results are as follows; 1. Of the men in 20s meeting the national average of physique, 4 men were selected and classified into 2 physical types according to their chest and waist circumference drops. One group had 20㎝ drop (Y type) while the other had 16㎝ drop (N type). Through evaluation performed by clothing construction professionals on the 4 upper bodice blocks drafted according to the existent drafting method and dressed on the 4 men, several problems have been found. These problems were adjusted and supplemented to make two new blocks. The fit of the new blocks were evaluated and proved to be satisfactory. 2. The following is the adjustments made to the existent men's torso patterns which had been utilized as the objects the first evaluation experiment. ① Though the back waist length of the pattern from the existent drafting method covered the center back length of the body in both Y type and N type, the front length did not causing it to stand away from the body. To adjust this, 2.0㎝ has been added to the center front length of each pattern so that the waist line could make a bar level to the ground. ② The shoulder line of the pattern from the existent drafting method had the tendency to fall backward. To make the shoulder line to fall in place, it has been moved 1.0㎝ to the front. 0.5㎝ has been added to the should length. ③ The neckline had a tendency to climb up. It has been lowered by 0.5㎝ until the line touched the center front neck point. ④ Though different in degree, the neck circumference did not allow enough width for both physique type causing the neckline to pull at side neck point with diagonal crease. To adjust this, 0.3㎝ and 0.6㎝ has been added to the Y type and N type respectively so that the neckline would touch the side neck point and the neckline could naturally fall into its original position. ⑤ Though different in degree, there was not enough space at the armhole causing wrinkles around this area. Therefore, 0.25㎝ and 0.5㎝ has been added to the front and back of the armholes of the Y and N types respectively. The armhole was made 1.0㎝ deeper only for the N type. ⑥ 1.0㎝ in the front and 0.5㎝ in the back were added to the side scam for the Y type while 0.5㎝ in the front and 0.25㎝ in the back were added for N type. This eliminated the unwanted wrinkles to give the silhouette a smooth look.

The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint is the correlation between UV-optical colours and Mg2 line strengths found by Burstein et al. (1988). The simplest interpretation of this phenomenon is that the UV strength is related to the Mg line-strength. Under this assumption, we expect galaxies with larger Mg gradients to have larger UV colour gradients. By combining UV imaging from GALEX, optical imaging from MDM and SAURON integral-field spectroscopy, we investigate the spatially-resolved relationships between UV colours and stellar population properties of 34 early-type galaxies from the SAURON survey sample. We find that galaxies with old stellar populations show tight correlations between the FUV colours (FUV-V and FUV-NUV) and the Mg b index, $H{\beta}$ index and metallicity [Z/H]. We have also derived logarithmic internal radial colour, measured line strength and derived stellar population gradients for each galaxy and again found a strong dependence of the FUV-V and FUV-NUV colour gradients on both the Mg b line-strength and the metallicity gradients. In particular, global gradients of Mg b and [Z/H] with respect to the UV colour across galaxies are consistent with their local gradients within galaxies, suggesting that the global correlations also hold locally. From a simple model based on multi-band colour fits of UV upturn and UV-weak galaxies, we have identified a plausible range of parameters that reproduces the observed radial colour profiles. In these models, the centers of elliptical galaxies, where the UV flux is strong, are enhanced in metals by roughly 60% compared to UV-weak regions.

Conventional SAW duplexer filters employ a 1/4 wavelength transmission line, which causes difficulty in fabrication of the strip line on the package. Its manufacturing process is also complicated, because it needs integrating process of the separate transmitting filter, receiving filter and isolation circuits. This paper concerns development of a new structure of the duplexer filter that has all the transmitting filter, the receiving filter and the isolation circuit as a one chip device. For composition of the duplexer, we design the component SAW ladder filters and the isolation network consisting of lumped inductor and capacitor elements. Performance of the whole duplexer is optimized by the nonlinear multivariable minimization of a proper target function, and the result is compared with that of commercial filters.

The single line hook fishery for giant pacific octopus, Parotopus dofleini is one of the important in coastal Kangwon-do of Korea, where was caught an average of 4,000 ton during the period of 1996~2000. The fishing gear is consisted of a single buoy line, a buoy and a hook. In this study, the responses of giant pacific octopus to single line hook gear were examined in an experimental tank using a video camera in order to know hooking mechanism and improve hook. Giant pacific octopus tend to envelop the bait with their arms by rush or slowly swimming towards it. When they rush to the bait, they show much feeding behaviour as withdrawing after enveloping the bait using two arms. But when they approach with slowly swimming to bait, they show feeding behaviour as stopping after enveloping the bait using one arm. and then, the highly hooking rate appeared more often in the case of latter then former. The average feeding time on a sardine, giant pacific octopus and pork fat showed the range of 1 to 30 min, 10 to 50 min, and 50 min to over 1 hour, respectively. This indicates that it takes longer time for giant pacific octopus to eat the tough meat than the soft meat. The performance concerned with hooking showed that the 'B' type hook with a short shank was more favorable than the 'A' type hook with a long shank. However, the 'A' type hook has the advantage of easy dropping out caught octopus, compared to the 'B' type.

This paper proposes a printing quality inspection system of film-type envelopment. Since the printing system is running at very high-speed (140m/min.) and the line error has very narrow width, we have to choose one-dimensional high-speed and high-resolution line scan camera. The vibration of the printing machine and the illumination environment make the inspection problem more harder. To obtain reliable inspection results, many software image processing techniques are applied and many parameters are tuned. The performance of the proposed system is proved by many simulations and long time real-plant experiments.

In 22.9kV-Y overhead lines, if there is an earth fault, high fault current causes surge type over-voltages around this place. There are generally two types of earth faults. One is an earth fault which occurs when a voltage line falls to earth line. The other occurs when a voltage line directly falls to the earth. This study presents an analysis method on the earth fault.

This study analyzed the characteristics and patterns of men's drawers panties to get basic data for their design. For this, drawers panties in 7 different brands (4: domestic brands, 3: imported brands) in terms of a front-center shape were collected, and the shape of men's drawers panties, characteristics of the materials, dimensions & type of patterns by the part and front-center patterns were analyzed. The study results found the followings: First, in terms of the shape of men's drawers panties, the front-center part were designed to rest the penis and scrotum in a natural and comfortable manner without a pee slit. They were seamless on the sides except for one product with side seams. Second, the drawer panties were made of elastic polyurethane materials. Specifically, domestic brand items used warm, elastic and durable nylon, polyester and rayon and polyurethanes while imported brands were mostly made of absorbent and sanitary polyurethanes. Third, regarding a size of drawer panties by part, imported brands were large in waist circumference. In terms of waist breadth at the front center, there was difference depending on an oval type. In addition, the front length at the front center differed by product, revealing difference in three-dimensional effect at the front center. The side length also differed greatly by product, which means that there might be a great difference in wear comfort. Fourth, in terms of the patterns of men's drawers panties, there was difference in side seams, center back seam and front-center patterns. Among a total of 7 products, only one product had side seams, and center back seams were found in two products only. Fifth, in terms of front-center patterns, the drawer panties can be divided into three types, creating three-dimensional effect not to give any pressure on the crotch: i) the cutting line only at the bottom of the front center part where the penis is rested, ii) puff created at the front center by adding a transverse line to the center line, iii) cutting transverse line to separate the penis from the testicles.

Aesthetic impression, structural stability, functionality during exercise, freedom of movement and physiological suitability should be considered when developing aquarobic wear for middle-aged women. We conducted a visual evaluation of the commercial aquarobic wear of the five brands (ARENA, TURN, RALLY, RENOMA and ELLE) with the highest market share and selected three items: one-piece type (OPT); two-piece type (TPT) and whole-body type (WBT). These are the most worn types of aquarobic wear for each brand. The G4 showed the best results in appearance evaluation of the shoulder strap width, front neckline, armhole line, side hip line and short pants length in the OPT category. The TPT had better ratings as the shoulder strap was located in the center of the shoulder, and the front and the back necklines were not too deep. The five items of WBT clothing received similar ratings for each element, so it is considered that the advantages are evenly distributed. No single design was a clear favorite. Based on the above results, continuous research on the development of aquarobic wear that is more suitable and preferable for middle-aged women should be conducted.
