This study establishes a fashion theory frame to forecast future fashion cycles of pants through analyzing past fashion cycles of pants through a diachronic method. Pants pictures from 1967-2012, post-industrialized period of Korea were analyzed. Representative pant styles, fashion cycles of pants and the relation of pant styles, length and width were identified. The total of 1006 pictures in fashion magazine published over 46 years were selected and analyzed using PASW 18.0 (statistical program). The results are as follows. For 46 years, representative pant styles were skinny, regular and bell-bottom. The first cycle period was from 1969 to 1992 and lasted 24 years. The second cycle period was from 1993 to 2003 and lasted 11 years. The third cycle is ongoing as of 2004. Fashion cycles have shown a general trend to be shortened. The relation between pant styles, length and width revealed related results; in addition, pant length and width changed significantly in a similar orientation. Fashion marketers can develop successful products using fashion cycle theory from these results.

In this study, we have developed the ergonomic pattern from the 3D human body reflecting cycling posture and extensibility of the stretch fabrics. Adjusting pressure level in the construction of athlete's tight-fitting stretch garments by reducing the original pattern is a challenging subject, which influence on the performance of the wearer directly. Therefore, in this study, relationships between the reduction rates of the 2D pattern obtained from the 3D human scan and resultant clothing pressure were explored to improve the fit and pressure exerted by reduced clothing pattern. Subjective wear sensations of the experimental garments were rated using a seven-point Likert scale on two consecutive days. While wearing the garments, subjects were asked to take five different postures including waist flexion, sitting and others. A Likert-type scale was used for the evaluation, with 7 points indicating the best fit in tight-fitting pants. Comparing 2/3T-pattern with T-pattern, the latter was superior to 2/3T-pattern in terms of adhere well to the waist and hip area in the 0.032 significance level. T-pattern was superior to 2/3T-pattern in terms of fitting and wear comfort. As results, the pattern obtained from the flexed body reflecting cycling posture already included the contraction and extension of the skin while cycling posture, so that the extra ease for movement and good fit was not need to be considered. The optimized reduction rates were determined with the proposed reduction rate, the resultant pressure range was within the range of $0.5{\sim}3.0gf/cm^2$ at eight locations on the body except front waist band and thigh band.

In apparel industry, the production of clothing for the global market, has it#s origin in its characteristics depending on hands on working style, according to the globalization of a fashion industry. These days, however, the globalized production is unable to keep pace with the short cycle of production due to the unpredictable change of the taste or demands in the local area, as a result, the industry has come to take a focus on the production and consumption in the circumscribed region. In this stream, the northeastern area, specially, Dalian which is renowned for a center of fashion was designated as a city of this study as a representative. The cultural, racial and geographical uniqueness, asks for the analysis, based on the individual local area on the part of Korean fashion company desiring to launch into China fashion market. The purpose of this thesis is to analyse the style, color, and items of street fashion in Dalian. I would contribute to the understanding the preference of fashion in northeastern area, thereby, affording a fundamental resources for designing strategies for Korean fashion brands in China. The period of investigation is about 5 weeks from 14 May 2006 until 18 June 2006, with combined use of camcorder and digital camera. The site was Victory Shopping Plaza, in center of city, also with Mycal, Ansung, Dasang department store situated in the Economic Development area. The result of this study are as follows: 1. Preferred clothing styles are casual styles(68%) rather than formal styles(32%). In the casual styles, sports casual(36.0%), character casual(29.5%), jean casual(2.6%) were listed. All kinds of clothes are tightly fitted due to the stretched fabric and knit fabric. 2. Preferred colors are white(31.1%), red(16.6%), black(15.8%) khaki(7.8%) and blue(7.6%) for tops, and black(34.6%), blue(27.2%), white(15.4%), brown(14.6%) for bottoms. 3. Preferred clothing items are T-shirt(36.5%), jumper(33.6%), jacket(20.0%), blouse(8.7%), etc.(1.2%) for tops, pants(91.4%), skirts(8.6%) for bottoms. In the pants, cigarette pants(34.6%), bell bottom pants(21.0%), cargo pants(19.9%), straight pants(15.9%) were listed respectively.

The purpose of this research therefore, was to conduct research on the actual state of manufacturers of cycle wears and the condition in wearing; to present the basic data to develop cycle wears which can lessen the trouble for the human body and an excellent feeling in wearing. For research on the actual state of manufacturers of cycle wears, three domestic companies were grasped. To inquire the condition in wearing, the method of questionnaire was used for 100 peoples consisted of male cycling professional players and ordinary peoples with the same tastes. As the result of research: The manufacturers were targeting for the professional players and men with the same tastes. They produced goods by themselves as well as in the form of subcontract, and they did not classify goods for male & female. Materials they used for cycle wears were mainly composed of jersey with spandex and nylon. The production ratio of cycle wears is shown as 80% for company A, 25% for company B, and 90% for company C. They make a pattern of cycle wears by a technical tie-up with foreign companies, or by the development of their own pattern. As the result of study on the present condition in wearing cycle wears according to each season, it was figured out that the users usually weard short-sleeved T-shirts with dividing zipper for summer upper garment, shorts most preferably for summer lower garment; long-sleeved shirts for spring and fall upper garment, and shorts with incision most preferably for spring and fall lower garment. Also, they usually weard jumpers with incision for winter upper garment, and long pants in which ankle parts of incision were tightened most preferably for winter lower garment.

The human body composed of concave and convex curvatures, and the current 3D scanning technology which involves inherent measurement errors make it difficult to extract distinct curvature plot directly. In this study, a method of extracting the clear curvature plot and its application to the cycling pants design were proposed. We have developed the ergonomic pattern from the 3D human body reflecting cycling posture. For the ergonomic design line on the 3D human body, the 3D information on the lower part of four male bodies with flexed posture was analyzed. The 3D scan data of four subjects were obtained using Cyberware. As results, the iteration of the tessellated shell was executed 100 times to obtain optimized curvature plots of the muscles on the body surface, and the boundaries of the curvature plots were applied to the design lines. Maximum(Max-pattern) and mean curvature plots(Mean-pattern) were adopted in the design line of the cycling pants, and performance of those lines was compared with that of conventional princess line(Con-pattern). The average error of total area and length in the 2D pattern developed from the 3D flexed body surface in this study were very minimal($4.58cm^2$(0.19%) and 0.15mm(0.46%)), which was within the range of tolerable limits in clothing production. The pattern obtained from the flexed body reflecting cycling posture already included the contraction and extension of the cycling skin, so that the extra ease for movement and good fit was not need to be considered.

In this study, a cycling smart wear for measuring cycling posture and motion was developed using a three-dimensional motion analysis camera and an IMU inertial sensor. Results were compared according to parts to derive the optimal smart device attachment location, enabling correct posture measurement and cycle motion analysis to design a pattern. Conclusions were as follows: 1) 'S-T8' > 'S-T10' > 'S-L4' was the most significant area for each lumbar spine using a 3D motion analysis system with representative posture change (90°, 60°, 30°) to derive incisions and size specifications; 2) the part with the smallest relative angle change among significant section reference points during pattern design was applied as a reference point for attaching a cycling smart device to secure detachable safety of the device. Optimal locations for attaching the cycling device were the "S-L4" hip bone (Sacrum) and lumbar spine No. 4 (Lumbar 4^th); 3) the most suitable sensor attachment location for monitoring knee induction-abduction was the anatomical location of the rectus femoris; 4) a cycling smart wear pattern was developed without incision in the part where the sensor and electrode passed. The wearing was confirmed with 3D CLO. This study aims to provide basic research on exercise analysis smart wear, to expand the smart cycling area that could only be realized with smart devices and smart watches attached to current cycles, and to provide an opportunity to commercialize it as cycling smart wear.

The present study was to analyze the trend of registration of design rights in apparel products and tc point out problems of current protection law to design. The research data was total 1,850 design rights in apparel that have been registered to the Korean Patent and Trademark Office from the first design registered in March 1, 1963 through those registered in April 24, 2003. All design rights were analyzed by the year, by the type of product, and by the type of applicant. And also design rights registered under the revised design registration system(without examination) were analyzed by the trait. The results of the study were as follows: (1) Sweater & polo shirts, underpants, and the Korean traditional dress were three major single categories registered in apparel : (2) 54.3% of total design rights in apparel was registered since the legal system of design rights has been revised in March 1, 1998 : (3) Registration by individual applicant were 71.7% of total; (4) About 60% of total design rights were for aesthetic, but in some categories such as vest. brassiere, undershirts, designs for function were more frequently registered than others. And total 68 design rights for the symbol of the organization or uniform, were registered in upper outerwear and pants : (5) As problems of the current legal protection system for designs, the term of “design”(expressed in Korean), double registration of similar designs, malicious intention to register other's trademark as his/her own design. The current legal system for design rights were more used for the product that has relatively long life cycle. And the revised law has been effective in encouraging the registration of design rights. However. the current design law still has some problems to be revised to prevent design rights or trademark infringement.

Cylindrical type ceramic filers, that is 60 O.D$\times$10t$\times$600L and 60 O.D$\times$10t$\times$1,000L were manufactured by vacuum forming processes using ceramic ray materials. For cylindrical type ceramic filters, porosity and bulk density were measured for, 80 to 90% and 0.3 to 0.4 g/㎤, respectively at uniform pore size of 41 to 45${\mu}{\textrm}{m}$. Bench scale candle filters (60$\psi$ $\times$10t$\times$600L) were tested using different dusts collected from many industries including chemical processing, glass processing and metal manufacturing pants. Collection efficiencies found out to range from 99.87% to 99.90%, while resistance coefficients from 1.1$\times$10(sup)11/$m^2$ to 1.7$\times$10(sup)11/$m^2$ . Full scale low density ceramic filters (60$\psi$ $\times$10t$\times$1,000L) were also tested at 1 atm, $600^{\circ}C$ to reveal the filtration efficiency, conditioning, and resistance coefficients using two different types of dust as chemical processing and metal refined processing. Darcys law resistance coefficients were measured to range 1.44$\times$10(sup)11/$m^2$ to 2.74$\times$10(sup)11/$m^2$, and collection efficiencies on the range 99.84 to 99.96%, Finally, results of long term performance test showed that filters were conditioned after 170hrs. Experimental conditions for effective filtration were examined under the condition 10 cm/sec face velocity, 3kg/$\textrm{cm}^2$ pulsing pressure, 5 min filtration cycle, and 300msec pulse opening time.
