This study aims to compare the ease of men's single-pleated pants patterns, and to analyze the fit and appearance through the 3D virtual garment system. The researchers selected five(four educational materials and one industrial pattern) slim-fit single-pleated pants which is the current fashion trend in menswear. The CLO 3D Modelist program was utilized to carry out the appearance evaluation through virtual wearing, opacity, and clothing pressure. The results showed that D pants had the greatest ease on the waist circumference, while C pants had the least ease. The E pants had the greatest ease on the hip circumference, then B pants and C pants showed less ease. Also, the E pants had the longest on the pants length, then D pants showed the shortest. In the appearance evaluation, A pants received the most favorable results, followed by D, B, E, and C pants, in descending order. The clothing pressure appeared to be mainly red on the waist, crotch, and hem in all pants, so the clothing pressure was high. From the results, we can understand that each of the 5 single-pleated pants patterns has different ease amount and silhouette.

The purpose of this study was to provide basic information for developing a smart taekwondo uniform with enhanced functionality for children by investigating the wearing condition and satisfaction of taekwondo uniform among taekwondo training children. The data were collected from 162 children living in Seoul and Daegu. For data analysis were performed descriptive statistics, ${\chi}2$ -test and t-test using SPSS Ver. 12. The results of the analysis are as follows. The results revealed that respondents wearing the general training uniform during their training period were the most. The dissatisfaction for the general training uniform was a high price, lack of symbolic, lack of functionality in textiles, lack of variety in design and unfittness of size in order. The developed uniform can adjust the length using a zipper type fastener, and can be used in all seasons as the lining is detachable. It also uses nano-silver material, and soil release finish. It enhances the functionality of movement by treating with raglan sleeve and sleeve hem velcro tape, and designs the upper garment in the draping. Safety is improved through attaching GPS, and elastic material is mixed in the neckline for putting on and off easily. Piece of cloth is added inside the closing of the upper garment. Rings are made for fixing the taekwondo uniform belt. Pocket is designed in the lower garment and colors are multiplied.

The performance sensitivity analysis due to manufacturing/alignment errors is performed for the Ku-band offset parabola antenna of the domestic Communications and Broadcasting Satellite. The performance variations due to reflector random surface error, which inevitably happens during reflector manufacturing, are statistically analyzed using RMS error and correlation interval. The impact on the antenna performance of the fred hem's position and angular errors is investigated, and the sensitive directions are identified. When the target tolerances are applied, the performance degradations are found to be within the loss budget or corresponding performance margins.

For multiple attacks through large networks e.g., internet, IDS had better be installed over several hosts and collect all the audit data from them with appropriate synthesis. We propose a new distributed intrusion detection system called SPIDER II which is the upgraded version of the previous standalone IDS - SPIDER I. As like the previous version, SPIDER II has been implemented on Linux Accel 6.1 in CNU C. After planting intrusion detection engines over several target hosts as active agents, the administration module of SPIDER II receives all the logs from agents and analyzes hem. For the world-wide standardization on IDS, SPIDER II is compatible with MITRE's CVE(Common Vulnerabilities and Exposures).

The aim of this study is to examine a structure of trousers worn by males in the western world during the 17th and 18th centuries in order to understand the characteristics of evolution in construction. it mainly examined engravings from these era because they provided me fine and detailed portrayals of what it needed to observe. Then, it classified them into models according to each era. it supplemented a flaw of depending on single type of studying material by examining other types of historical materials such as historical paintings and documents for comparative analysis of materials and decorations and previous studies on preserved historical documents to observe the examples of structures of trousers. Secondly, it studied both historical documents and previous studies on the trousers patterns used back in those days, analyzed the characteristics of each designing method by actually draping these patterns, and observed the differences in these completed patterns to understand the characteristics of changes in fashion design skill. As for the changes in length, these patterns show only a slight difference around above and below the knee line. However, the widths of waist, hip, girth and hem were significantly altered over the years to reduce wrinkles and the cutting lines became more refined to make the clothes fit to the body. As a result, a simple but fine patterning technique was born. In particular, new methods in cutting and sewing were invented for detailed parts such as waist, pocket, front and slit.

The Assyrians usually wore two types - the tunic and the shawl. These two types were worn alone, or in combination and changes were introduced by varying the proportions of the tunic or shawl. The tunic appeared to be of the sleeves are short and reaching to the ankles or shortened to knee length according to the rank. Assyrian shawl pattern can be divided into five distinct styless. Many of the styles were suitable for costumes to wear in religious plays and pageants. Fringed shawls were the trademark of forma1 Assyrian costume. The usual badge of rank was a long fringed shawl. Intermediate rank wore shawl with short fringes and lower grade wore no shawl at all. The military costume was comparative uniformity : conical helmets was regarded as Scythic in character, short, fringed tunics, wide belts or helmet, round caps and long tunics covered in metal scales, belted at the waist. Assyrian woman costume was the long tunic with fringed hem and a long fringed shawl or was a plaid tunic and wide belt over it. They wore gold crown and horned Cap and tiara, ugal (head-dress) and the most ordinary earrings were the drop and the cross shape and necklace was made of the coloured stones and bracelets ended with heads of animal was regarded as Scythy style or adorned with a rosette at the centre.

The purpose of this study was improvement of the pants fit for obese women. The results were as follows; 5 obese women in their 20s and 30s were selected for the testing 3D body. They showed no significant differences in all items, comparing with the data of 5th Size Korea body dimensions. The average waist circumstance of the subjects' 3D body dimensions was 87.0 cm and hip circumstance was 102.4 cm, and their obese body types had similar mean values. Based on the survey results and the 3D body dimensions of 5th Size Korea body dimensions, a pants pattern to supplement their body type and improve a fit was designed with waist circumference(88 cm), hip circumference(103 cm), crotch length(27.1 cm), thigh circumference(62 cm), pants length(97 cm), pants hem line circumference(44 cm). Based on the detailed design of ready made pants and the study results of young obese women's preference for pants design, pants of straight silhouette and semi-tight fit which have waist line lowered by 3.5 cm from the waist circumference line, 3.5 cm belt width, no front dart and one back dart, were manufactured with 100% black cotton and cotton spandex mixed fabrics.

The hyper-geometric distribution software reliability growth model was recently developed and successfully applied Due to mathematical difficultv of the maximum likclihmd method, the least squares method has hem suggested for parameter estimation by the previous studies. We first summarize and compare the minimization criteria adopted by the previous studies. It is theo shown that the weighted least squares method is more appropriate hecause of the nonhomogeneous variability of the number of newly detected faults. The adequacy of the weighted least squares method is illustrated by two numerical examples. Finally, we propose a new method fur predicting the number of faults newly discovered by next test instances. The new prediction method can be used for determining the time to stop testing.

The aim of the study was to look into the construction methods of historical corsetry and compare them with the construction methods of corsetry today. Through a comparative study, it was concluded that the design, material, sewing and functions of corsetry of a certain period are sum of the clothing techniques and fashion of the time. Corset was first appeared at the end of the 16th century. It has been through many changes in terms of items, materials, patterns, sewing methods in order to make right silhouettes of the time. Now corsetry has been developed into various items such as waist nipper, all-in-one, nipper bra, and girdle. All these items have a common purpose, that is to improve the body shape. The corsetry of the past was made of non stretchable materials, so they used to restrict body movements, and required individual fitting several times. Due to the development of thin durable stretchable fabrics, functional bones, and advanced sewing machines, construction methods of seam, hem and opening are simplified compare to their predecessors. Consequently corsetry became less weighted, easy to wear, easy to wash and easy to mass produce. Yet they have consistency in sewing techniques such as using bones or wires to support bodice shape, using durable twill fabrics over plain for attractive body shapes.

In this paper, a novel triple-mode cavity structure, designed for compactness and operating at 850 MHz, is analyzed. A cylindrical dielectric resonator is loaded into a metallic cylindrical cavity. Previous study has been focused on the analysis of the cylindrical dielectric resonator, but in this paper, the effect of the cylindrical metallic cavity has been analyzed. Enclosing the dielectric resonator inside the metallic cavity increases the resonant frequency of the dielectric resonator; however, this increases the quality factor and introduces the possibility of installing coupling screws. The principle of generation of triple-mode was investigated by parametric analysis. The generated triple-mode is TE011 mode and two orthogonally generated HEM121 modes. By adjusting the radius of the dielectric resonator, the height of the dielectric resonator, or the radius of the cylindrical metallic cavity, three modes could be coincided. However, the height of the metallic cavity keeps three modes separated. The mode characteristics of the proposed cavity are analyzed using a full-wave electromagnetic (EM) simulation. The proposed triple-mode cavity could be developed to triple-mode filter using a coupling screw, and the commercial application for the miniaturized filter below 1 GHz could be expected.
