Although the surface of aluminum alloy has good corrosion resistance property, the surface of the aluminum rolling stock should be painted for good appearance and protection of the body. For better painting of the aluminum carbody, the surface must also be well pretreated. In this paper, painting process of the aluminum rolling stock is described and the test results of the painted surface is presented. As accumulated data concerning to the painting technology for the aluminum rolling stocks are absent in our country, the presented test results will be helpful for mass production of aluminum rolling stocks in the near future.

High glossy painting and UV lithographic painting as painting methods for wooden furniture have played a positive role in enhancing the diversity of furniture design, which has been proved by the analysis on the relationship between the change in the diversity of design and painting methods of graduation projects (wooden furniture) presented by graduates of local universities, as a focus of this article. Since the development of new painting methods has the potential to develop aesthetic characteristics of wooden furniture, many design experiments are needed to improve decorative features of furniture, such as the application of high glossy painting and UV lithographic painting.

A deep learning based real-time painting surface inspection algorithm is proposed herein, designed for developing an autonomous inspection drone. The painting surface inspection is usually conducted manually. However, the manual inspection has a limitation in obtaining accurate data for correct judgement on the surface because of human error and deviation of individual inspection experiences. The best method to replace manual surface inspection is the vision-based inspection method with a camera, using various image processing algorithms. Nevertheless, the visual inspection is difficult to apply to surface inspection due to diverse appearances of material, hue, and lightning effects. To overcome technical limitations, a deep learning-based pattern recognition algorithm is proposed, which is specialized for painting surface inspections. The proposed algorithm functions in real time on the embedded board mounted on an autonomous inspection drone. The inspection results data are stored in the database and used for training the deep learning algorithm to improve performance. The various experiments for pre-inspection of painting processes are performed to verify real-time performance of the proposed deep learning algorithm.

The study of a new expression within Korean ink painting that meets the demands of the times has continued, resulting in various expressions with acrylics, handycoat, objects and installations, crossing over from traditional Korean painting techniques. A 'margin' was both a very important space and esthetical matter that expresses 'Ki', 'Distance', and 'Omission' in traditional sense when addressing Korean ink painting Its expression methods and concepts, however, have changed today. A 'margin' through Montage technique can be a significant example in understanding the expression methods of today's Korean ink painting. This is because the margins in Montage make the meaning of the work various and flourished and deeply construct the surface with a double-layered structure, instead of using a single layer. These 'margins' created by Montage are spaces where different images conflict, divide and continue with each other and where a reconciliation between different spaces is accomplished. Furthermore, they establish more vitality and truthfulness to life through both the images conflict and reconciliation. After the adoption of Post-modernism Art in Korean ink painting, the characteristics of the 'margin' in Montage style by the division of surface are an 'acceptant's participatory imaginative space'; where viewers fill the margins with their imaginations ; an 'abandoned space' ; where unnecessary parts are deleted for more live surface ; and a 'strategic space', where the work enriches the structure and contents of surface by using margins strategically.

The present study investigated the adhesion and corrosion resistance of subsequent electrophoretic paint (E-paint) on "electroless" paint coated AZ31 Mg alloy, which was formed by immersion of AZ31 Mg alloy in E-painting solution. It was found that with increasing immersion time of AZ31 in E-painting solution, the amount of paint deposited by electroless process increased but it decreased the electrochemical equivalent of E-painting process and the adhesion of the subsequent E-paint layer. The E-paint on electroless paint coated AZ31 contained pores with the highest pore density and the largest pore size was obtained on the samples with electroless times of 2 and 5 minutes, respectively. Results of the salt-spray test showed an accelerated growth of blisters over the entire surface of the sample immersed for less than 5 minutes whereas blisters were observed only in the vicinity of the scratch in case of samples treated for 15 and 30 minutes. The E-paint on AZ31 with shorter electroless immersion time in E-painting solution was found to have good adhesion and better corrosion resistance.

본 연구에서는 가상 공간(VR) 사용자에게 반응형 페인팅 경험을 제공하기 위한 포스 피드백 기반 햅틱 페인팅 인터페이스를 제안한다. 제안하는 시스템에서는 헤드 마운트 디스플레이(HMD)를 착용한 사용자가 스타일러스 타입의 햅틱 장비를 이용하여 시각적 피드백과 햅틱 인터페이스의 촉각적 피드백을 동시에 활용하며 가상 공간에서의 표면기반 3차원 페인팅을 생성해낼 수 있다. 특히 햅틱 인터페이스는 가상 공간 상에서 페인팅 브러시와 페인팅과의 물리적 상호작용을 구현하여 VR 페인팅의 반응형 피드백을 제공한다. 이는 가상 공간에서 사용자의 공간적 인지력 향상에 도움을 주고 부족한 시각적 피드백을 보완할 수 있다. 이를 통해 사용자는 불필요한 반복적 페인팅 작업을 줄여 페인팅 작업의 효율을 높이고 페인팅의 결과물을 향상시킬 수 있으며 결과적으로 보다 실감나는 VR 페인팅을 경험할 수 있다.

A new electrostatic rotary atomizing painting equipment using air turbine was developed for high transfer efficiency. Based on the overall design requirements of painting equipment, basic design specifications of the equipment parts such as air turbine and atomizing disk ate defined from the present conceptual design model. Air turbine is designed with the section profile of NACA airfoil, and its internal flow field is analyzed by commercial CFD code. Atomizing disk is designed to achieve the ligament type spray of paint with the use of visualization technique. Various experiments and tests are conducted to investigate the spray and the transfer characteristics of newly-designed painting equipment, and the measurement results are compared with the those of conventional painting equipments. The comparison results show the present painting equipment is superior to the conventional ones in the aspects of transfer efficiency and coating surface characteristics.

The aim of these studies is to confirm the red and blue painting damages during the fire suppression of wooden cultural assets by using the loaded stream charge extinguishant. As a results of these experiments, the ingredients of extinguishant existing on the surface of wooden cultural assets were perfectly eliminated by the water washing only. Any changes on the surface of wooden cultural assets couldn't be detected. Moreover, any color changes of the red and blue painting didn't occur.

This study provides a comprehensive evaluation of general characteristics of sized silk fabrics for the painting purpose. Two particular types of silk fabrics used for painting background were compared: a recreation of historical material and a mass produced material of present day. The sizing process made the surface characteristics of the silk fabrics more suitable for painting. The dyeing properties of the fabrics were related to the surface area of the fabrics, and had no significant effect on their mechanical properties. The antibacterial activity of the tannin-based natural dyestuffs were maintained after the sizing. The performance assessment by the KES-FB system showed that the fabrics are more prone to deteriorate after the sizing because the glue layer receives the most of the physical stresses.
