The purpose of this research is to examine the expression methods of Haute Couture designers' high value-added jacket designs, In order to achieve this, the positions and sizes of the design component items of tailored jackets designed by Haute Couture designers from the 1940s to the 1970s were analyzed. The results of the analysis are as follows. First, the silhouette changed while leading the contemporaneous fashions, and such changes could be confirmed by the width and length of the jacket's shoulder, chest, waist, and hem that determine the silhouette. Particularly, the length of the chest changed which signifies that the depth of the armhole was playing an important role in the production of high value-added jackets in relation to the sleeves and the fit of jackets. Second, the position and the size of the dart are the components that can express the fit of a jacket and the designer's creativity, The starting point position of the dart and the position passing by waist, and the position of the end of the dart were placed in the position beyond B.P. depending on the designer's creativity and techniques, deriving the changes of the silhouette and creating high value-added jackets. Third, the tailored collar, which was a three-dimensional component made up of the upper collar, gorge line, lapel, and break line, was an important component that could express high value-added jackets. Changes in the width and the height of the break line position of the sides of the neck were represented as changes in the neck size of the collar, and changes in the vertex locations of the upper collar corner-point, the gorge line (the corner-point of the lapel and V zone) were also represented as diverse tailored collar designs. And the differences in the width and the length of each component of the collar were related to each other and represented as changes in the slope and angle of the collar outline. Fourth, the changes in sleeve designs of the jacket were in such items as the width of the sleeve opening, the width of the sleeve hem, and the length of the sleeve, and were represented as diverse sleeve designs such as widened sleeve opening types, and straight line types.

This paper proposed a sizig system for men's jackets in order to improve the clothing fitness and rain the productivity. The sizing system was classified according to 3 age groups. Figure types were categorized by shoulder angle and body shape. The size interval of the basic dimensions was established at regular intervals centering around their means. Altogether, 15 size charts were developed based on the frequency distribution. Size designating measurements for jackets were height, chest girth and waist girth. Size intervals were 3cm for chest and waist girth, 5m for height, and 2cm for waist and hip girth. Considering the cover factor, charts with a limited number of sizes were suggested with necessary measurements for each figure type of each age group.

The permeation of $Ca^{2+}$ ions through the materials such as polyvinyl chloride (PVC) and non-halogenated flame retardant cross linked polyolefin (FR-XLPO) used for CN-CV underground distribution power cable jackets was investigated. The permeation of $Ca^{2+}$ ions was found to increase with the increase of time. The FR-XLPO showed higher permeation of $Ca^{2+}$ ions, by a factor of about two, than the PVC. This was explained by the destruction of structural integrity caused by mixing a large amount of mineral flame retardant such as $Mg(OH)_2$ used to impart non-flame ability to the jacket material.

Early investigations focused mainly on manipulating the confinement effect to develop a reinforced concrete column with lateral hoops. Based on this legacy model, Li's model incorporated the additional confinement effect of a steel jacket. However, recent experiments on plain concrete cylinders with steel jackets revealed relatively large discrepancies in the estimates of strength enhancement and the post-peak behavior. Here, we describe a modified constitutive law for confined concrete with an unbonded external steel jacket in terms of three regions for the loading stage. We used a two-phase heterogeneous concrete model to simulate the uniaxial compression test of a $150mm{\times}300mm$ concrete cylinder with three thicknesses of steel jackets: 1.0 mm, 1.5 mm, and 2.0 mm. The proposed constitutive model was verified by a series of finite element analyses using a finite element program. The damaged plasticity model and extended Drucker-Prager model were applied and compared in terms of the level of pressure sensitivity for confinement in 3D. The proposed model yielded results that were in close agreement with the experimental results.

In the current study, a force-based fiber frame finite element model of FRP concrete structural members has been developed. For compressive behaviors of confined concrete wrapped by FRP jackets, the multiaxial behavior of concrete has been considered with the equivalent tangent modulus of concrete. The behavior of FRP jackets has been modeled using the mechanics of orthotropic laminated composite materials in two-dimensional stress states. The force-based finite element formulation is based on the force-interpolation functions within the element without using the displacement shape functions to satisfy the equilibrium in element levels.

The present study aims at developing standardized patterns of ready-made Korean traditional costume for women in twenties and at suggesting classified standards so that consumers can buy high quailty clothes easily without dissatisfaction on unsuitable measurments. It was found from the dressing experiment results that new-concept patterns of Korean jackets onsidering women's bodies were seriously required because jackets fabricated by conventional patterns were not properily fitted to their bodies. During the processes of patten development, dressing experiment, and subsequent pattern adjustment, measurment standards classified by women's bodies were established, and new standardized patterns were developed in accordance with characteristics of women's bodies. These findings suggested that future studies on the pattern modification should be achieved continuously in consideration of ages, tastes, and fashions of modern women consumers.

The purpose of this study was to develop motorcycle wear with built-in airbag protection for enhanced comfort and fit. Based on the survey results, a motorcycle jacket was designed using. Aauto CAD. This study concentrated on the wearing comfort comparison of the motorcycle jacket developed from this research with that of and foreign goods. To evaluate the wearing comfort, 3 types of motorcycle jackets were used. The results of this study were as follows. : From an Analysis of the differences in wearing comfort, the motorcycle jacket developed proved to be more convenient than the 2 types of foreign motorcycle jackets in terms of the standing and handle grip posture. This effect was due to the curved pattern of the neckline part of the airbag. The air pressure of the airbag must be improved.

In the case of hospital buildings, where seismic design requirements are very high, existing structuresand especially those attacked by past earthquakes, appear, often, unable to fulfil the necessary safety prerequisites. In this paper, the retrofitting of hospital buildings is investigated, using alternative methods of repair and strengthening. Analysis of an existing hospital building in Patras, Greece, is performed. The load-bearing system is a reinforced concrete system. Two solutions are proposed: strengthening using concrete jackets around column and beam elements and application of viscoelastic dampers for the increase of the stability of the structure. Adequate finite element models are constructed for each case and conclusions are drawn on the efficiency of each rehabilitation method.

Based on the experimental data presented in part I of these companion papers, a semi-empirical model is proposed for axial stress-strain curves of reinforced high-strength concrete square columns confined by aramid fiber reinforced polymer (FRP) jackets. Additionally, a three-dimensional finite element model is developed to simulate the mechanical behaviors of the columns. In the finite element model, both material nonlinear and contact nonlinear are taken into account. Moreover, the influence of contact nonlinear (i.e., the end friction on the contact surface between test machines and specimens) is investigated deeply. Predictions from both the semi-empirical model and the finite element model agree with the experimental results, and it is also demonstrated that the friction coefficient of end friction notably affect the properties of columns when it ranges from 0.00 to 0.25.
