Recently, the population of Asian people has increased constantly in the United States., but appearances, culture and thoughts of Asian people are different with Americans in various ways, especially body shapes. Despite the recent developments in apparel size ranges in U. S. A., few changes have been made in sizing for Asian Women. Size ranges designed for Asian Women are not available on the mass market in U. S. A. They have many difficulties in finding clothing that fits well. Especially they do experience such as clothing problems in varying degrees. Therefore this research was designed to investigate the specific clothing problems of Asian Women in relation with size and fit, Asian Women's present means of resolving their clothing problems in U. S. A. 60 Asian Women in Twin cities, Minnesota were interviewed during the period of October, 1991. Data were analyzed by descriptive statistics for demographic information on the selected sample and the chi-square test for relationships between the independent variables and clothing problems. The results indicated that most respondents had shopped in a department store and 38.3% of the respondents answered rarely-fit of suit. Also 40% of the respondents answered that pants length was too long. There were significant relationships between the demographic variables i.e. age, marital status, occupation, height and clothing problems of Asian women.

A Study on the Development of Brassiere Pattern for Elderly Women The purpose of this study is to develop functional and sensible brassiere for elderly women. For this purpose, 6 elderly women(aged between 65 and 69) were sampled to be measured for their body sizes and tested for their bressiere wearing. he results were as follows; 1. In order to develop the basic patterns of elderly women's bressieres, 90B size was selected and then, their bressiere fitting was tested. The foundation pattern of the size 90A was proved for the body by the wearing tests. Each angle and length of the parts on the basic line of the breasts played an important role on setting the pattern. 2. As based on the body surface shell extracted from a plastic mold(photo.2), the cup of brassiere pattern were applied to the body surface shell(photo.4), and full side stretch-wings were applied to 13% reduced body size. The design pattern of elderly women's brassiers were characterized by a round wired as well as a full cup(3piece) embracing the entire breasts. 3. As the result of the wearing test, the excellence of the experimental brassiere was recognized objectively, with high marks in all the items(fig. 6). The experimental brassiere was covering the whole breasts to cope with change according to breasts loosing. It was designed to support the breasts firmly.

This paper presents a novel makeup simulation method for powder application. We propose a color appearance model for powder coated skin that is simple but yet capable of producing realistic visual results. From the photos of several artificial skins before and after powder application, the translucency and thickness parameters are achieved by fitting the color model to the photos. Thickness patterns of powder application on actual human face skin is also extracted, and used in makeup simulations on photos of different human face to give more visually appealing results. From experiments, we found that the simulation results are quite realistic, and expect that the proposed makeup simulation can be used as a virtual coloring test in the cosmetic labs.

The purpose of this study was to develop a well-fitting bodice basic pattern for high school irk. Two bodice patterns were first made based on the most recent existing drafting methods and sensory evaluation was done on the patterns by the present researchers Two high school girls possessing standard physical condition tried and evaluated the functionality of the garments made by the two bodice patterns. Based on the results of the evaluation, a new bodice basic pattern was developed. The new bodice basic pattern was drafted by long measurement method. The dimensions of new bodice basic pattern were as follows. Bust circumference=B/2+4cm, Arms hole depth=C.B/2+1.5cm, Back width=B/6+4cm, Front width=B/6+3cm, Back neck width=B/12+0.5cm, Back neck depth=Back neck width/3cm, Front neck width=B/12cm, Front neck depth=B/12+0.5cm.

The demand for more accurate and realistic 3D urban models has been increasing more and more. Many studies have been conducted to extract 3D features from remote sensing data such as satellite images, aerial photos, and airborne laser scanning data. In this paper a technique is presented to extract and reconstruct 3D buildings in urban areas using airborne laser scanning data. Firstly all points in a building were divided into some groups by height difference. From segmented laser scanning data of irregularly distributed points we generalized and regularized building boundaries which better approximate the real boundaries. Then the roof points which are subject to the same groups were classified using pre-defined models by least squares fitting. Finally all parameters of the roof surfaces were determined and 3D building models were constructed. Some buildings with complex shapes were selected to test our presented algorithms. The results showed that proposed approach has good potential for reconstructing complex buildings in detail using only airborne laser scanning data.

The aim of the current study was to predict shape recovery behavior of Ni-Ti shape memory alloy (SMA) wire after loading-unloading and after wire drawing. The superelasticity of SMA was analyzed by a hyper-elastic model for the Mullins effect using ABAQUS. Firstly, tensile tests and loading-unloading tests of the Ni-Ti SMA wire with a diameter 1.0 mm were performed using an MTS servo-hydraulic tester. The parameters for the Mullins effect were computed by ABAQUS based on curve-fitting of the loading-unloading test data. The proposed FE-model predicted the shape recovery of Ni-Ti SMA after wire drawing. Finally, the effectiveness of the model was verified by drawing experiments. The wire drawing experiments using the Ni-Ti SMA were conducted on a drawing machine(1ton, 50mm/s). In order to evaluate the shape recovery of Ni-Ti SMA, the drawn wires are annealed for 30min at $450^{\circ}C$.

HEV(Hybrid Electrical Vehicle) is considered as one of the next generation vehicles. To develop the HEV, there must be a reliable simulator, by which the capacities of the power resources are tested, and the parameters of the HEV are optimized before developing the real model of the HEVs. This process can save the money for designing the HEV system and improve the system without experiments. Matlab Simulink is familiar to mechanical engineers and the program can simultaneously provide a system model and a controller in one program. Nowadays, the Simdriveline toolbox which is used for analysis a power-train system is applied to build a dynamic model for a HEV system. In this study, we make a HEV simulator with the Simdriveline toolbox and develop a controller. There are two simple strategies, applied to the controller. One strategy includes a power split ratio and a shift map which are created by user. Other strategy calculated an appropriate amount of resource's torque along specific results, and this is useful when users can't develop a fitting controller. The methodologies for configuring the simulator and its control system are presented in this paper.

This study was conducted to get best fitting frequency distribution for the annual run- off and to simulate long series of annual flows by single-season first order Markov Model with comparison of statistical parameters which were derived from observed and synthetic flows at four watersheds in Seom Jin and Yeong San river systems. The results summarized through this study are as follows. 1. Hydrologic persistence of observed flows was acknowledged by the correlogram analysis. 2. A normal distribution of the annual runoff for the applied watersheds was confirmed as the best one among others by Kolmogorov-Smirnov test. 3. Statistical parameters were calculated from synthetic flows simulated by normal dis- tribution. In was confirmed that mean and standard deviation of simulated flows are much closer to those of observed data than except coefficient of skewness. 4. Hydrologic persistence between observed flows and synthetic flows simulated was also confirmed by the correlogram analysis. 5. It is to be desired that generation technique of synthetic flow in this study would be compared with other simulation techniques for the objective time series.

The objective of this research is to validate the BRQ(Brand Relationship Quality) Construct perceived by fashion product consumers. In order to establish and verify the BRQ scale, qualitative survey and quantitative survey were conducted together. 1592 copies of questionnaire were distributed to women in their 20s to 40s living in Seoul and other metropolitan areas from Dec. 26, 2005 to Jan. 8, 2006, and 723 copies of them were used for statistical data. Samplel(n=482)was used for empirical analysis, and sample2(n=241) was used for cross validity test. The data was analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and Pearson's Correlation Analysis. BRQ emerged from exploratory factor analysis as the hierarchical construct composed of six facets including 'self-connective attachment', 'symbol/mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge'. As the fit of this structural model was not good as a result of Confirmatory Factor Analysis, it was revised to have better fitting. Finally, empirical survey results indicate the hierarchical construct consisting of eight distinct BRQ facets including 'love/commitment', 'self-connection', 'symbol', 'mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge' as best representing the final 39item BRQ Scale. Reliability, construct validity, and cross validity of the construct were verified.
