The current trend in automotive finishing industry is to use more electrostatic rotating bell (ESRB) need space to their higher transfer efficiency. The flow physics related with the transfer efficiency is strongly influenced by operating parameters. In order to improve their high transfer efficiency without compromising the coating quality, a better understanding is necessary to the ESRB application of metallic basecoat painting for the automobile exterior. This paper presents the results from experimental investigation of the ESRB spray to apply water-borne painting. The visualization, the droplet size, and velocity measurements of the spray flow were conducted under the operating conditions such as liquid flow rate, shaping airflow rate, bell rotational speed, and electrostatic voltage setting. The optical techniques used in here were a microscopic and light sheet visualization by a copper vapor laser, and a phase Doppler particle analyzer (PDPA) system. Water was used as paint surrogate for simplicity. The results show that the bell rotating speed is the most important influencing parameter for atomization processes. Liquid flow rate and shaping airflow rate significantly influence the spray structure. Based on the microscopic visualization, the atomization process occurs in ligament breakup mode, which is one of three atomization modes in rotating atomizer. In the spray transport zone, droplets tend to distribute according to size with the larger drops on the outer periphery of spray. In addition, the results of present study provide detailed information on the paint spray structure and transfer processes.

To evaluate the effects on health by exposure to low dose organic solvents, the author analyzed the air concentration of mixed organic solvents (toluene, xylene, butylacetate) at worker's breathing zone during painting, some laboratory findings of blood (WBC, RBC, Hb, Hct, SGOT, SGPT, TC, TG, HDL-C, LDL-C, IgG, IgM, IgA and IgE) and urine (hippuric acid, urinary protein, urobilinogen), surveyed the subjective symptoms those were obtained from 35 male workers exposed to mixed organic solvents, and 25 male workers not exposed to organic solvents who worked in car repair workshops in Taejon area from December 1, 1995, to February 29, 1996. The results were as follows: 1. The mean concentration of urinary hippuric acid of car painting worker group (organic solvent exposure group) was 0.76$\pm$ 0.21 g/l, which is significantly higher than that of non-exposed group. 2. In hematologic findings, the values of RBC, TC, LDL-C, IgG and IgE in the exposure group were significantly lower than those of the nonexposed group, but SGOT and SGPT in the exposure group were significantly higher than those of the non-exposed group. 3. Urinary hippuric acid levels showed positively correlated with toluene, urobilinogen and HDL-C levels, but those were negatively correlated with RBC, LDL-C, IgM levels. 4. Rates of the subjective symptoms such as "dizziness", "appetite loss", "weight loss", "palpitation", "chest tightness", "sore throat and eye discomfort", "tingling sense and acrodynia", "illusion or hallucination" and "decreaased motor power" were significantly higher in the exposure group than those of the non-exposed group.

Manufactures of automotive repair finishes are tending to reduce more and more the level of volatile organic compounds (VOCs) in their paint processes in order to comply with increasingly strict environmental legislation. The production of high solids paints is a way to solve this problem. However, the application of high-solids paints is limited primarily by the viscosity of resin which is strongly related to painting ability: the higher solid content, the lower desired property. In this study, alkyl copolymer with low viscosity was synthesized by the introduction of the monomers with long-side chains and functional groups which improve flexibility and cross-linking density, respectively. The solid content of the paint prepared with the synthesized resin was 80wt% and its VOCs was reduced by 20%, compared to the commercialized paint. Also, the physical and mechanical properties of coatings on steel sheets were similar to commercialized one.

The purpose of this research are to identify the nature of artistic beauty of Kokuryeo dresses and to apply the artistic beauty, formative uniqueness, and esthetic value of Kokuryeo in the modern Korean dress design for creation of new designs. Significance of this research lies in the fact that beauty of traditional dresses possesses highly valuable importance for application to modern fashion design processes. Kokuryeo dresses basically comprised of Yu, Sang, Go and Po, and contains within abstract beauty along with emphasis on geometric elements like dots, lines, and surfaces. Red, Black, Violet, Verdant and scarlet colors were moderately used against the mainly white canvas, and different colors were often used for the top and the bottom. Silk, Hemp cloth and Wool were used for different social levels or ranks, and from the wide variety of colors and patterns of the dresses, such as Round-patterns, Cloud-patterns and Vine-patterns, worn by the people illustrated on the wall paintings, it appears that various materials were used. Vertical hems, Yu (shirts), Sang (skirts), noblemen's dresses, kings' dresses, etc. from Kokuryeo tomb wall paintings were applied, and various dying methods, natural materials and sewing methods were used to recreate the unique features of Kokuryeo dresses in modern designs in an attempt to recreate the esthetic value of Kokuryeo dresses.

The purpose of this study was to investigate Renaissance wall-covering fabrics through Flemish paintings, that provides the details of the origin and development of background of modern wallcovering. The methods of the study are as follows. First, the background of textile development of Flanders in the 14^th to 16^th centuries were examined through a prior study. Second, the shape and use of wallcoverings in paintings painted during that time were analyzed and the process of changing to modern forms was studied. The residential environment with many stone buildings in relatively humid and cold weather created a need for decorative fabrics. Back then, the wool and flax fabric were not allowed to be worn on the body, so the materials were used for the development of interior fabrics. The characteristics of wall covering in Flemish paint can be summarized with movable, allegory, and decoration. Movable stems from the arrival of the emerging aristocrats of Flanders, who had enormous commercial trade and carried decorative fabrics; the mobility has become an allegory in reality as the royal and aristocratic use of wall-decorated fabrics is the symbol of authority. In addition, unlike Italy, where silk was procured from the East, fabrics manufactured using flax and wool were not suitable for clothing in terms of religion and practicality and were used to decorate walls.

In Malaysia, figurative painting has increasingly become a means for artists to pose questions about presumptions of power and assumptions of history. The body, its potentially breached boundaries and defenses, forms an integral component of the battle for political influence. The degree of control over one's own and other people's bodies has become a measuring stick to determine the power of potential political leaders. Anxiety about boundaries and access to powerful bodies is intertwined with the questions of who has the right to hold power; the relevance of moral bodies and of what comprises an ideal self or selves. These questions are raised in intriguing ways in contemporary Malaysian art. While eschewing a direct take on current politics, Malaysian artists have increasingly turned to the body to address issues in Malaysian history, culture and the distribution of power. This paper will explore some works by three artists in particular, Wong Hoy Cheong, Nadiah Bamadhaj and Ahmad Fuad Osman use the figure to problematise dominant narratives in Malaysian history. Their work variously challenge political, racial and gender hierarchies and in so doing, reveal them as social constructions.

In this paper, we have designed an optical measurement system for authenticity of paintings. Using a simple and compact optical measurement system, the surface characteristics of paintings could be measured, and we obtained information about paintings. First, the paintings that were painted in various colors could give characteristic information on the color of paintings. Second, tomographic information about the surface of a painting could be obtained, using a line laser. To assess the reliability of the optical measurement system, forgeries looking like the originals were created, and we could distinguish the originals from the forgeries through experiment. Thus, we could obtain data about the paintings and create a numerical database.

This study aimed to develop a modern textile design based on the formability of Frank Stella's paintings and to develop and present a fashion design that combines modern sensibility as a 3D virtual clothing program. The formative characteristics of Frank Stella's work were 'unity due to regular stripes', 'asymmetry due to geometric surface division', and 'decorabilitydue to colorful use'. Based on this, costume patterns and textiles based on Frank Stella's paintings were developed and six 3D virtual fashion design works were produced. The conclusion was as follows. First, it was confirmed that Frank Stella's work has a very wide range of applications to fashion products as abstract expression and minimal simplicity coexist visually. Second, various colors and forms of Frank Stella's paintings could be developed using textiles with visual formability, and originality as a fashion work applied with paintings could be maximized. Third, the development of 3D fashion using virtual programs had the ease of time efficiency, cost reduction, and spatiotemporal expansion of work processing compared to the actual costume production process. In addition, the simulation of 3D virtual wear made it easy to modify and recover the position of the textile to be applied to the costume and create a new design in the process of transforming the position of various textiles. It is expected that this study results will be used as basic data for the future conversion content industry in the painting and fashion industries.
