In research on behavioral studies, significant attention has been paid to the stage-sequential process for multiple latent class variables. We now explore the stage-sequential process of multiple latent class variables using the multivariate latent class profile analysis (MLCPA). A latent profile variable, representing the stage-sequential process in MLCPA, is formed by a set of repeatedly measured categorical response variables. This paper proposes the extended MLCPA in order to explain an association between the latent profile variable and the latent group variable as a form of a two-dimensional contingency table. We applied the extended MLCPA to the National Longitudinal Survey on Youth 1997 (NLSY97) data to investigate the association between of developmental progression of depression and substance use behaviors among adolescents who experienced Authoritarian parental styles in their youth.

This study examines the prati fashion style. prati fashion refers to a practical fashion, the most sought-after trend and newest fashion concept. This trend emerged as a response to the trio of minimalism, the recent economic downturn and the modern life style, and has led to powerful fashion lines and items. Therefore, this study is to understand and analyze the prati fashion style, with its focus on the 2010 modern fashion collection that embodied functional, economic, and minimal styles. First, the functional style realized by new materials provides comfort and allows multi-style changes. Second, the minimal style adds detailed changes to minimal silhouettes. Finally the economic style means easy to wear and easy to match items at affordable prices. The analyses stated above found that the prati fashion brought about a new paradigm to society, and influenced social, cultural and economic aspects of our daily life. It also helped find solutions to economic problems of this era. Drawing global attention, the prati fashion has functional, design and economic values, and thereby influences the shift of market paradigm.

A geometric kernel is the library of core mathematical functions that defines and stores 3D shapes in response to users'commands. We developed a light geometric kernel suitable to develop CAD/CAM application systems. The kernel contains geometric objects, such as points, curves and surfaces and a minimal set of functions for each type but does not contain lots of modeling and handling functions that are useful to create and maintain complex shapes from an idea sketch. The kernel was developed on MS-Windows NT using C++ with STL(Standard Template Library) but it is compatible with UNIX environments. This paper describes the structure of the kernel including several components: base, math, point sequence curve, geometry, translators. The base kernel gives portability to applications and the math kernel contains basic arithmetic and their classes, such as vector and matrix. The geometry kernel contains points, parametric curves, and parametric surfaces. A neutral fie format and programming and document styles are also presented in this paper.

Nowadays calligraphy technique is widely utilized in diverse areas throughout the world. It is adopted in the visual environment of modern people comprehending from graphic design areas such as advertisement, package, symbol marks, logotypes, and movie posters to modern abstract paintings. It is because its dynamic and suggestive power of expression as symbolic and kinetic representation has been appreciated anew. In response to modern people's aversion from the mechanical and artificial digital environment as well as from the uniform, official, and modernistic trend, calligraphy technique is attracting people's attention as a new expressive style with oriental mysticism and emotional intimacy. Therefore, this study aims at illuminating the history of calligraphy, understanding its characteristics, searching for the expanded value of modern paintings and graphic designs, and ultimately contributing to the propagation of visual languages and expressive styles. In addition, this study attempted to establish the concept of Calli-Illust, which combines oriental painting techniques and materials and calligraphy techniques, and to explore for its potential uses in order to expand the area of illustration. According to the results of this study, calligraphy technique is a painting style of abstract expressionism, contributing to the expansion of the territory of a new formative area. Furthermore, this study proved that it is necessary to develop new expressive styles to overcome the limitation of design styles based on western rational, logical, and geometric functionalism, which have been received uncritically in the design environment of diversity. What is more, the concept and definition of calli-illust, which has been understood as a part of the concept of calligraphy so far, were clarified Research on calli-illust is just in its beginning stage. The present researcher expects that deeper and more extensive studies will be carried out in the future, so that calli-illust can be applied to communication design in various ways.

The quick response(QR) system is very popular in Korean apparel companies. However, the usage of QR system was not known well. The purpose of this study is to identify the usage of the quick response decision support system(QR DSS) and postponement manufacturing in the Korean apparel company. The researched company was the only one which used the QR DSS. The researchers carried out the depth interview with the QR decision makers of the company. This company had 14 brands, and had used the QR DSS since January, 2008. The results are as follows: The QR DSS was supportive computer software program, and it helped the staffs to make agile decision about QR repeat production of clothing. The QR DSS automatically calculated the related data, and suggested the expected sales volume and the proper supply amounts of the styles. There were four functions in QR DSS : 'QR Alert', 'Proper Supply Amount Simulation', 'Sensible QR', and 'Supply/Sales Simulation by Item'. The men's clothing brands effectively used 'Supply/Sales Simulation by Item' function. And the women's clothing brands effectively used 'QR Alert' function. This company also used the postponement production system for QR repeat production. The postponement production was conducted with four methods : the yarn stocking, the grey fabric stocking, the dyed fabric stocking, and the fabric sourcing. The men's clothing brands usually used of the yarn stocking methods and the dyed fabric stocking methods. The women's clothing brands usually used the grey fabric stocking methods. By using QR DSS and postponement production system the company was able to shorten the lead time for QR decision making.

The primary purpose of this study is to suggest a new methodology for calibration of a continuous price response function and to compare the differences in the price response function with and without choice set information. Through the new methodology, the two-staged conjoint analysis, the continuous price response function far jeans market was calibrated. Three steps were required to complete the two-staged conjoint analysis. Step one provided respondents with both a written and a visual description of two different randomly selected styles and colors of denim jeans. In step two respondents were asked to choose the combination of attributes they intended to purchase. Based upon the literature review, these four attributes included: brand, style, price, and color. Respondents were required to assess their purchase intentions for 32 combinations by marking Yes if she/he would purchase a given combination and No if she/he would not purchase a given combination. This allowed for identification of each respondents choice set. Instructions in step three required respondents to rate each combination marked Yes on a scale of 1-100, with one as least likely to be purchased and 100 as most likely to be purchased. This value served as the dependent variable for estimating the parameters in the model. Furthermore, the empirical study shows that there is a difference in price response function with and without choice set information. Therefore, when one calibrates a price response function far a given brand, we can recommend to include choice set information in his/her research.

This study aims to understand the consumer consciousness of the interior design by experiencing the interior space of the model house provided by the construction company. For this, the author investigated the spatial images about the apartment interior design and the satisfaction level depending on the experiential elements. Survey questionnaires were distributed to people who visited six model houses. Subjects were asked about the experience about the interior space of the model house. Their response to the experiential elements was analyzed with 5-point Likert scale and was computed as frequencies, percentages, and means. For the spatial image characteristics, adjectives were substituted for the image scales. As a result, the author found out the following: First, the interior space was commonly directed to the soft image, which was mixed with modern, noble, decent, dynamic and natural styles depending on the companies. The trend of each interior design basically had static, soft and vague images, and partially had two kinds of tendencies: the one was mild and natural, and the other was modern and elegant. Second, as the strategic modules of the experiential marketing, five experiential elements were investigated to find the satisfaction level through the model house interior space. The emotional element got the highest point followed by the cognitive element and the active element, while the sensible element and the relative element got the lowest point. Third, consumer response was generally positive toward the model house interior design provided by the construction company. It is necessary to make up for the design that can give an aesthetic pleasure with familiar images, rather than give a firm recognition about the design.

In response to the need of developing children's wear design using traditional elements, this study purposed to develop fashion designs emphasizing contemporary images based on the symbolism and formativeness of traditional dresses. For this study, we reviewed the definitions and symbolism of traditional colors and traditional patterns using previous research, and classified them according to formative shape. In addition, this study made three pieces of dress and developed unique designs by applying the traditional patterns and elements of Korean traditional dress styles. The research methods were as follows. First, we examined the images of Korean traditional colors and classified the symbols and meanings of the colors. Second, we identified the types of patterns, and classified them into shapes and symbols. Third, we designed and made actual works by applying traditional patterns. Based on the theoretical studies as presented above, we developed contemporary casual hanbok designs for children by applying symbolic and formative traditional patterns and using DTP (digital textile printing).
