This study understands rockers of today and supplies basic data of design and manufacture studying pattern change of rockers arisen in West, there is the purpose. Also, this study is investigated by dividing theoretical background of rockers, 7 kinds of American traditional rockers and European rockers from 18th century to opening part of 20th century and contemporary rockers since 20th century. The theoretical background and the style of 2 rockers (Windsor rocker, Boston rocker) were investigated to study the stylistic changes of rockers. Originally a rocker was invented by a European farmer around 1700. It developed to a household which equip practicality and comfortablness in the United States than Europe. Early rockers in a primal form appeared in the 1740s in the United States. American early rockers connected skate to established chair bridge. Rockers are deep connection with family's emotion. Rockers can provide playing functions for children and medically treating functions for adults. Windsor Rockers developed by attaching skate is mammy bench and according to shape of back form bow or hoop-back rocker, birdcage rocker, comb-back rocker. Windsor Rockers formed peculiar American tradition of craftsman furniture through structure that have a unique back of a chair and round seat. Boston Rockers were the first chairs made by mass production method. They show a particular shape with S-curve style seat and rectangular crest at the upper part of the back. Often Crests were decorated by stenciled pattern with curled leaves such as rosettes and scrolled designs.

This study is to enhance the competitiveness of the domestic cosmetic industry and provide basic materials needed for a design idea by analyzing perfume bottles designed by Rene Lalique. The methods of this study are documentary research and demonstrative research. The documentary research considered the theoretical background with a focus on related domestic and international literature, previous research, and Internet materials. The demonstrative research extracted photo materials of the bottle designs of Lalique from domestic and international web sites along with literature that classified them into shapes, colors, materials, and patterns that analyzed the general characteristics and chronologic changes. The results of this study are as follows. The curve-oriented shape was common and multi-colors were used more frequently than a single color in the 1910's. Colorless-transparent glass and a flower patterns were used frequently for materials and patterns, respectively. Lalique reflects this style in his bottle designs because the Art Nouveau effect in the 1910's. In the 1920's, curved and straight shapes had a similar percentage. The use of multi-colors and one type of glass bottle increased versus the 1910's. Similar to the 1910's, a flower pattern was used most frequently. This suggests that Lalique was influenced by the established Art Nouveau and was also interested in the Art Deco style, In the 1930's, an organic curved shape was common. Unlike the 1910's and 1920's, a single color was more common than multi-colors. The one type of glass bottle and a geometric pattern were common for materials and patterns, respectively. The Art Deco style was reflected in the bottle design of Lalique in the 1930's.

Nowadays, the amount used carpets are on the increase, according to the improvement of life-style. The pleasantness of carpet is caused by the properties of pile, because the most carpets are made pile fabric. For that reason, a study on the compressional properties of carpet is very important issue. This study has been carried out to investigate the differences of compressional properties in various acrylic carpets which were Cut, Tufted, Jacquard and Shag. Each acrylic carpets was transformed to 4, 6, 8 mm of pile height, as results of transformation, we could get the pressure-thickness curve and pressure-deformation curve. The results are summarized as follows. 1. Rate of compression increases, compressive resistance and compressive elasticity decr-eases, as pile height increases. 2. Regardless of pile height, compressive elasticity reached the limit in recovery period at about 10 minutes. 3. Work of compression increases, as pile height increases. 4. Work of compression decreases, as apparent density increases. 5, Cut-type carpet has the best cushion.

The purpose of this study is to help user understand the basic principles and interfaces of each program, and to provide a base material for the development of more efficient apparel CAD systems to compensate for each program's shortcomings by comparing the function of three apparel CAD systems: Yuka CAD, Opti-tex, and Style CAD. For this purpose, the skirt waistband and sleeve armhole line creation process were selected based on these two criteria. 1) There is a big difference between principle and method between CAD systems. 2) When CAD system is used rather than paper drawing process, the process is shortened and convenience is high. In this study, pros and cons and supplement point of each CAD system are suggested by comparing the functions of the CAD system performing the selected drafting process by four criteria: icon, key, method, and characteristic point. As a result of the study, it was confirmed that the three CAD systems differ in the basic principle and interface environment. As a result of analyzing the skirt waistband method function, it was confirmed that the band line is formed directly on the outline of the skirt and the band dart recognition function is the most efficient function and as a result of the analyzing the sleeve armhole line method function, it was confirmed that the curve generation function using the shape of the actual curve measure and the length adjustment function through the automation of the dimension calculation is the most efficient function.

This study develops pant patterns using body shape, measurement and shell mesh data to decide optimal women's pants according to styles with excellent size, fit and shape for different individuals and silhouettes. Standard landmarks, lines, triangles and structures were set on a 3D scanned lower body shell to represent women in their twenties and flattened as a 2D pattern. Patterns were created and analyzed according to culotte, formal, slacks and tight type considering crotch shape, location of the crotch point, and adjusting waist darts. Flattened patterns were rotated to compare existing methods. The crease lines were then set through the hip protrusion point and compared. The main factor of the pant pattern were extracted, total rise, crotch depth, crotch width, angle of center line, shape of the center line curve, the thigh width, the amount of waist dart, and crease line position. With going tight style from the culotte, the fits are closer to the figure with minimized thigh circumference, the dart amount decreases, the crotch depth increases, the crotch extensions were shorter, and the angle of the center back increased. The total rise is U shape for culotte and is closer to V shape as the silhouette tightens. T-test of appearance evaluation of the developed pant pattern were conducted after analyzing measurements and shapes of each styles. The results of the developed patterns were superior to existing patterns in accordance to hip line between body and pants as well as appearance evaluation. We found systematic mechanisms among pattern factors that create various pant silhouettes. Evidence on classification of the silhouettes of traditional types of pants were explained objectively through the process of playing out 3D forms.

The present study investigated the developmental pattern of Korean mothers' depressive symptoms from a week prior to birth through four months postpartum in a nationally represented survey sample in Korea, using a Latent Growth Curve model. Mother-reported four factors-maternal self-efficacy in parenting, father's participation in childcare, a number of hours mothers worked per week, child's emotional temperament-were examined as the predictors of depressive symptoms over time in the context of Korean culture. Effects of maternal depressive trajectories on their infants' developmental outcomes at the first year were also examined. Findings were as follows: First, mothers' reports of depressive symptoms decreased at the first month after birth and then increased again during the first 4 months postpartum. Second, mothers' perceived low spousal involvement in childcare, low parental self-efficacy, and their infants' difficult temperament at four-month old had significantly positive relations to the initial level of maternal depressive symptoms whereas the low spousal involvement in childcare and low maternal self-efficacy factors significantly predicted the changes of trajectories of maternal depressive symptoms. Third, the trajectories, in turn, predicted warm and responsive maternal parenting style at the fourth month. Subsequently, the parenting style had a significant longitudinal impact on the development of children's communication, problem-solving, and personal-social abilities. Based on these findings, awareness, preventive and interventional programs might be built to facilitate Korean mothers suffering severe postpartum depressive symptoms and further promote optimal early development of Korean children.

At the turn of the 19C, the first development, spreading to the all classes that peculiar attitude of mind associated with the term prudery. The second changes of habit which affected both sexes and their undergarments were the novel idea of personal cleanliness. Drawers appear to have been of two lengths, short, when worn under breeches, and long when worn under pantaloons and trousers. The dandy wore corsets for beauty. In the early part of the 19C, the differences between day and evening style came to be accentuated. Not only the beau, but the soldier and hunting man were addicted to stays. The high standing collars of the early 1800s became fairly low in the middle of the century. in mid of the 19C, a woolen under-vest was worn next to the skin and studs were an usual fashion. At about 1850 the bottom of the shirt was cut in a curve. For evening dress the elliptic collar was introduced.

The Psychology of putting on clothes has close relation with sexuality, and eroticism is important in clothing. Present article aims to understand eroticism correctly and to make it evaluated as an art in modern fashion and as an aesthetic to express woman\`s beauty. Modern eroticism in fashion may be divided into direct, indirect and symbolic expression made. The result are as follow: First, direct made, a representation of desire into direct, indirect and symbolic expression of body or physical curve with tight garment. Second, indirect made, a see-though technique using association, represents sexual appeal by imagination on body area hidden by clothes made of see-through material. And third symbolic made express sexual libido by representing body area or clothes which symbolizing woman\`s sexuality using materials like fur or silk. Eroticism in modern clothing, therefore, should be understood as a beauty that is expressed by human artistic desire. Further studies are needed to explain the characteristics of eroticism in every culture because human nature is apt to from diverse kind of cultures.

The purpose of this study is twofold: it suggests appropriate sizes in menswear slim-fit jackets according to brand zones and number of buttons, as well as jacket patternmaking methods according to jacket styles by surveying and comparing the overall present status of patternmaking and production for both men's slim-fit and classic-fit jackets. The researcher conducted interviews with patternmakers of sixteen brands with prepared questionnaires. Data were analyzed by descriptive statistics using SPSS 12.0. The results of this study are as follows: first, for the production ratios of jacket style, the jacket styles' respective proportions differ distinctly according to brand zone. Second, for a jacket with the same number of buttons according to brand zone, the size in character-casual brand zone (character casual can be defined as high quality brands producing designer style clothes) is slightly bigger than the men's formal suit. As the number of buttons increases, there are increases in the chest, waist and hip circumference; on the other hand, the front neck width and the distance from the shoulder neck point to the bottom of the lapel both decrease. Furthermore, the amount of wearing ease in the chest, waist, upper arm circumference, and sleeve curve is less in slim-fit jacket styles than in classic-fit jacket styles. Fusible interfacing alone is used in slim-fit jackets, while sew-in interfacing is used in combination with fusible interfacing in classic-fit jackets. This research concludes that when slim-fit men's jackets are manufactured, appropriate patternmaking and manufacturing methods should be considered.

Objective : To compare radiographic analysis on the sagittal lumbar curve when standing, sitting on a chair, and sitting on the floor. Methods : Thirty asymptomatic volunteers without a history of spinal pathology were recruited. The study population comprised 11 women and 19 men with a mean age of 29.8 years. An independent observer assessed whole lumbar lordosis (WL) and segmental lordosis (SL) between L1 and S1 using the Cobb's angle on lateral radiographs of the lumbar spine obtained from normal individuals when standing, sitting on a chair, and sitting on the floor. WL and SL at each segment were compared for each position. Results : WL when sitting on the floor was reduced by 72.9% than the average of that in the standing position. Of the total decrease in WL, 78% occurred between L4 to S1. There were significant decreases in SL at all lumbar spinal levels, except L1-2, when sitting on the floor as compared to when standing and sitting on a chair. Changes in WL between the positions when sitting on a chair and when sitting on the floor were mostly contributed by the loss of SL at the L4-5 and L5-S1 levels. Conclusion : When sitting on the floor, WL is relatively low; this is mostly because of decreasing lordosis at the L4-5 and L5-S1 levels. In the case of lower lumbar fusion, hyperflexion is expected at the adjacent segment when sitting on the floor. To avoid this, sitting with a lordotic lumbar curve is important. Surgeons should remember to create sufficient lordosis when performing lower lumbar fusion surgery in patients with an oriental life style.
