Training is one of the representative application fields of virtual reality technology where users can have virtual experience in a training task and working environment. Widely used in the medical and military fields, virtual-reality-based training systems are also useful in industrial fields, such as the aerospace industry, since they show superiority over real training environments in terms of accessibility, safety, and cost. The shipbuilding industry is known as a labor-intensive industry that demands a lot of skilled workers. In particular, painting jobs in the shipbuilding industry require a continuous supplement of human resources since many workers leave due to the poor working environment. In this paper, the authors present a virtual-reality-based training system for spray painting tasks in the shipbuilding industry. The design issues and implementation details of the training system are described, and also its advantages and shortcomings are discussed based on use cases in actual work fields.

Vehicle manufacturing plant is a typical mixed-model production system. Generally it consists of three main shops including body shop, painting shop and assembly shop in addition to engine shop. Each shop contains diverse manufacturing processes, all of which are integrated in a form of flow line. Due to the high pressure from the market requesting small-volume large variety production, production planning becomes very critical for the competitiveness of automotive industry. In order to save costs and production time, production planning system is requested to meet some designated requirements for each shop: to balance the work load in body and assembly shops, and to minimize the number of color changes in painting shop. In this context, we developed a sequencing module for a vehicle production planning system using the ILOG Solver Library. It is designed to take into account all the manufacturing constraints at a time with meeting hard constraints in body shop, minimizing the number of soft constraints violated in assembly shop, and minimizing the number of color changes in painting shop.

'Fantasy', the central notion of this essay, is discussed here more as a new paradigm in order to describe the structure of a work of art than as a stylistic characteristic proper to a specific genre of art. It means the whole situation and experience produced by two connected terms 'corporeal subject - screen'. Roland Barthes explained the 'semiographic painting' by Andre Masson as a field in which happens a certain connexion between the impulse of subject and the image, which views the painting not as a physical object but as a 'cinematic screen' ; painting may be redefined as a dream or a fantasy of the corporeal subject. And such an idea of 'art as fantasy' is closely related to the recent theoretical attempts consisting in abolishing the vision-centered conception of art since Renaissance. In this essay, the notion of fantasy as an aesthetic model is sketched by means of the Freud's notes on the fantasy 'A child is being beaten' and Lyotard's more advanced analyse on its attributes and operations. In Lyotard's analysis, fantasy is defined as a 'bloc' or a 'matrix-figure' featuring simultaneous conversion between the active and the passive, sadism and masochism, and coexistence of imcompossible meanings. In this sense, fantasy may be given to us as an analogical model from which we can outline the aesthetic characteristics of electronic media art involving virtual reality and interactivity.

Considering the physical quality of the wall body in this study we tried to select a replenishing that is proper for filling the cracked part of the painting wall layer and apply the natural adhesives that have traditionally been used, investigating whether it is possible to substitute those for the chemical adhesive which is used at present time. The result of this study showed the red algae adhesive was, in a weathering environment, as safe as the synthetic resin originated from the polyvinyl acetate which is used generally on the present spot, and it was concluded that although the starch adhesive displayed its superiority in enhancing the strength of the earth mortar and its work disposition, it seemed proper for it to be used as a filling adhesive for the first or midterm layer because it showed a surface hardening phenomenon. And also the glue and fish glue were judged they were not qualified as a filling adhesive due to mold occurring in a environment of high moisture that is a biological problem, showing at same time a weak physical feature in a weathering environment. Therefore it would be possible to use the red algae adhesive or starch one substituting them for the original one sold on the present market, if among natural adhesives the weak points of the them were to be corrected.

회화적 렌더링의 궁극적인 목적은 주어진 영상을 가지고 사람이 직접 그린 듯 한 회화적 느낌을 표현하는 것이다. 이러한 회화적 느낌을 표현하기 위한 요소에는 브러시의 굵기, 방향, 질감, 그리고 생성된 브러시가 캔버스에 그려질 것인가를 판단하는 기준설정 등이 있다. 본 논문에서는 에지 밀도를 이용해 브러시가 캔버스에 그려질 것인가를 판단하는 기준을 설정하는 알고리즘을 제시한다. 에지밀도란 일정 영역에서의 에지의 양을 나타낸다. 이와 함께 정적 격자 단위로 그려질 위치를 찾는 것이 아닌 동적 격자단위로 찾아가는 방법을 사용하고 브러시의 일관된 방향성을 위해 방향 보간을 한다. 또한 텍스처를 가진 다양한 브러시를 사용하여 질감을 표현한다. 에지의 밀도정보를 이용한 그려질 판단 기준설정, 통적 격자에 의한 위치선정, 일관된 브러시의 방향, 그리고 텍스처를 사용한 질감 표현 과정들을 통해 더 사실적인 오일 페인팅(oil painting)의 효과를 얻을 수 있다.

In this study, we analyzed the images of women in Korean society through the female body expressed in nude paintings from Korea. The study included a literature study and a case study. Through prior research, we examined the history of nude paintings in Korea and the way people conceptualized the female body in Korean society. The case study focused on nude paintings of Korean artists, produced since 1910, when Western painting concept was first introduced to Korea. The social perspective of the female body in Korea was categorized into the three concepts: Eros, Motherhood and Power. Next, we examined the role of drapery and clothes in expressing these three concepts. Drapery and clothes played active roles in hiding and emphasizing the female body, showing the psychology of a woman or the artist's intention, showing the entire mood of the work, and giving three dimensional feeling and elegance to the work. We could see that the role of clothes changed from expressing a virtuousness in the past to stimulating a voyeuristic gaze in the present.

This study aims to find methods that prevents aging of buildings paint coating and that limits defects in construction. Defects in painting can occur in four stages: pure paint, during painting, after the paint coating has dried, and after some period of time has passed after coating. Paint may become bad due to precipitation of pigments, formation of membranes, and seeding during manufacturing. Therefore, it is important that the paint is well mixed and kept airtight at a cool, dark place. Indents, paint brush strokes, orange peel, separation of colors, and paint running and spreading during the paint work process can be prevented by using high quality materials and applying a high-level of construction method. After the paint coating has dried, boiling, yellowing, poor drying, poor bonding, and/or glen deficiency may occur. These are influenced by the levels of cleanness of the dried product, drying temperature and hydration. Then, when the coating has been left dried for some period of time, cracking, peeling, scaling, swelling, discoloring, and/or rusting may develop due to the ultraviolet and contaminants in the air. Since these defects occur due to inappropriate construction schedule and/or hot and humid condition, one must use weatherproof materials. Furthermore, poor paint color may be caused by contamination in the sample plate, discoloration, and/or discrepancies in colors which are due to material differences, level of glossiness, degree of dispersion, dual color property of metallic colors, precipitation of pigments, etc. One should achieve reduction in construction cost and effectiveness in paint work by limiting contaminations in the construction site and strictly observing to construction regulations.

Renaissance Age is called the Period of Discovery because of great development of the economy and the science, and is known the Period of scientific analysis of Man and of interest of Nature out of a blind obedience in the Middle ages. Especially in visual art architecture, painting and sculpture, the rational spirit of Renaissance actually and distinctly communicates the meaning of Work through the scientific and mathematical expression after a finding Perspective by Brunelleschi. So the puropse of this study is to clarify the substancial meaning of Renaissance Art by investigating the expression applied Perspective to the works of Brunelleschi's architecture, Donatello's sculpture and Masaccio's painting.

The demand for the re-painting of steel bridges is increasing, but surface treatment is still centered on human resources for on-site re-painting processes. Worker safety accidents continue to occur because the work is performed in a narrow space. Recently, PS balls with excellent surface treatment have been used for blasting, but the working environment is poor due to the large amount of dust generated. In this study, an effective surface treatment method using impeller blasting equipment was developed. The correlation between steel ball size, impeller rotation speed, and exposure time was studied to optimize the efficiency of the surface treatment.

The main purpose of this study was intended to analyze the image of N대-Expressionism represented in the late of 20th century fashion design. By the late 1960s and the early 1970s. the prevailing notion of modernity, which had pushed the limits of art beyond previous boundaries, had begun to lose its urgency. Critics called the new pluralistic era which the West was entering Post-Modern. Furthermore, the predominance of America and the New York scene is diminishing, and artistic leadership is now international. Post-Modernism dialectcally made denial of Modernism as likely as New Image Painting and Decorative Pattern Painting Art in 1970's and it was availed as a dialectcal means for the pre-diction of new comings that would be appeared at painting art in 1980's. New Image Painting has been called as Neo-Expressionism. The N대-Expressionists selected human's feature because appeared flankly, directly irregular agitation in the visual effect and they believed human's destructive and amputate body was cruelty. So they express it on the surface canvas. Under the these background, the image of Neo-Expressionism was represented in the late of 20th century fashion design such as the upside-down image of human feature, the image as ameditation on German myth and history, culture, the ecletic image is made of use a mixture of material. The properties of composition, line, color, texture, and form, common to all plastic art, are now more readily recognized and historically valued in every work. That is, individuality, humanity, and the human condition have been at the core of most Western art and Fashion design. Especially Fashion design has been one of the principal instruments used to examine our nature and to promote the notion of growth, self-understanding, and change.
