When a truck cab is conveyed at a constant speed by a hanger and immersed into the painting reservoir, it may fall off from the hanger by buoyancy. In order to reduce the buoyancy, on the bottom of a cab panel are holes placed, which allow paint to flow into the inside of a cab. In this study, a differential equation is derived which can be solved numerically by using 4th-Order Runge-Kutta method to calculate transient behavior of the buoyant force with sizes and locations of the holes given. The solution is utilized to optimally determine sizes and locations of the holes.

Owing to high speed internet technologies, video conferencing systems are exploited in our home as well as work places using a laptop or a webcam. Although eye contact in the video conferencing system is significant, most systems do not support good eye contact due to improper locations of cameras. Several ideas have been proposed to solve the eye contact problem; however, some of them require complicated hardware configurations and expensive customized hardwares. In this paper, we propose a simple eye gaze correction method using the three-dimensional (3D) affine transformation. We also apply an image in-painting method to fill empty holes that are caused by round-off errors from the coordinate transformation. From experiments, we obtained visually improved results.

This paper analysed the architectural images on Pleasant Gathering of Leeum, Samsung museum of art, which has been assumed as a work of the Koryo dynasty. Through the comparison between the unique wooden structure at roof edge on the building images and real architectures, it found the buildings on the painting were from China Fujian(福建), not from Korea. It also analysed the color painting on buildings, trees, themes from previous famous paintings and dresses to confirm these images were came from the early period of the Ming dynasty. It is a very unique painting containing various information on the Fujian ancient architecture, but its architecture drawing is not as skillful as typical ancient Chinese paintings.

The manufacturing techniques were studied by investigating a precise analysis on wall structure, features of materials and the painting layer of the bracket mural paintings at Daeungbojeon Hall in Naesosa temple. The wall frame is a single-branch structure, and The mural paintings are composed of 3 layers which are a support layer, a finishing layer and a painting layer. The support layer and the finishing layer are an earth wall that sand and clay such as Quartz, Feldspar, and etc. are mixed. The support and the finishing layers have a combination of medium particle sand and smaller than fine particle sand in the approximate ratios of 0.8:9.2 and 6:4, respectively. Therefore, the aforementioned ratio of sand with medium or large particles is relatively higher in the finishing layer than the support layer. As a result of a precise analysis on the painting layer, it has a relatively thick ground layer for painting which is maximum $456.15{\mu}m$ by using Celadonite or Glauconite and the paintings were colored by using pigments such as Atacamite, Kaolinite or Halloysite, Oxidized steel, and etc. on it. The manufacturing style and the painting techniques of an earth wall are included in the category of the Joseon Dynasty style that have been studied up to now, but the facts that the finishing layer has a high content of sand and a middle layer and chopped straw have not been identified. These are remarkable points in terms of structure and materials, and can be crucial in the evaluation of the state of conservation of mural paintings or preparation of a conservation plan.

The purpose of this study is to consider the relationship between point of view and prospect behavior occurring in the experience of a painted landscape. This study analyzes one hundred scenes from the 'real landscape painting' by Kyumjae, one of the most famous landscape painters in 18th century Korea. The results of the study are as follows: 1. It clarified that Kyumjae's real landscape painting's 100 scenes have many view points such as roads, bridges, pavilions, mansions, towers, terraces, hillsides, bases of mountains, broad flat roots, brooksides, and ferries that are apt to occur in the experience of a landscape. The spatial characteristics of view points are expanded fields of vision, evening and night scenes, edges of landforms and structures from which to improve ones vantage point. 2. It showed that 99 out of real landscape painting's 100 scenes depict a view point'to look'and 79 of 'to look through', 73 of 'look around'and 24 of 'to look over'. 3. It showed that real landscape painting's 100 scenes depict that the view point 'to look' is mainly upon a road from which people are looking over an elevated landscape such as the top of a mountain or rockwall. The view behaviors of looking down are depict 15 pavilions, 14 mansions, 2 broad rocks and 10 mountain tops on which people experience landscapes such as fields, rural communities and streams. The view behaviors to look depict 33 ships, 24 roads, 24 pavilions, 19 mansions and 12 terraces on which people experience landscapes such as distant views of mountains, rivers and landscapes. The view behaviors to look around to obtain orientation of landscape are depict 16 pavilions, 10 mountaintops. To glimpse on the way of journey depict 33 ships and 29 roads. To look over depict 11 mansions and 6 pavilions on which experience borrows the landscape. To look through landscapes such as rivers, mountains and rockwalls depict 15 roads, 14 pavilions and 11 mansions. To exchange looks depict 30 ships, 14 roads, 12 pavilions and 12 mansions. We expect that these results might give clues toward the experience of landscapes and the practice of landscape design methods which select viewpoints, and in the design of view points suitable to prospect behaviors.

EuiJae Hu BaekRyun is a symbol of Honam Namjonghwa and is respected as a teacher of Honam culture. He is from JinDo and is a relative of Sochi Heo Ryun and a disciple of Misan Heo Hyeong. The spirit of traditional Namjongghwa and the dignity of painting faithful to its technique have been obtained by themselves, and have made it his own. EuiJae organized a 'Yeonjinhoe' in Gwangju to raise his students. After liberation, a house was built under Mudeungsan Mountain. And showed another aspect as a social educator who emphasized and practiced national spirit while being a tea ceremony man. He excelled in Chinese poetry and painting theory, and expressed a unique field in calligraphy. especially worked as an artist good at poetry, caligraphy, and painting. EuiJae showed exceptional talent, especially in landscape painting. His tendency to paint was to follow Ye Chan's technique of drawing with a dry brush, placing importance on the energy of learning, and constantly trying new experiments with the technique of gisaeng. The world of EuiJae's works can be divided into three periods, based on the signature using the trend of painting or the change of perspective pursued, the era of EuiJae, the era of EuiJaeSanin, and the era of EuiDoin, which had a tendency of independent painting. EuiJae's contribution surpassed the artistic historical assessment that he had formed a big stem for the authentic Namjongghwa of Korean painting culture, which was part of Oriental painting. And recognizing that he was a fundamental teacher connecting modern times through the actual scenery based on NamDohwa's universal spirit and regional characteristics and the creative succession of emotions, he should inherit his passion for artistic spirit and tradition and experimental spirit.

Hanging paintings are used for special ceremonies in Buddhist temple. They are stored in special storage box called "Gwaebulgwae" which means storage box for a hanging painting. Studies regarding pigments, background fibers and textiles of hanging paintings are carried out with many data in the field of conservation science. However, there are only few studies for the axes of hanging paintings and storage boxes. In this study, species identification for wooden axes of hanging paintings and storage boxes from the Joseon dynasty are carried out. Hanging painting of Beopjusa temple, Magoksa temple, Sudeoksa temple, Gaeamsa temple, Sudosa temple, Bukjangsa temple, Dorimsa temple, Tongdosa temple and Daeryeonsa temple are selected. Sampling is carried out from the axes of hanging paintings and storage boxes. 81 samples are collected from hanging paintings and storage boxes. As a result, 51 hard pines of Pinus spp., 8 Tilia spp., 6 Juniperus spp., 5 soft pines of Pinus spp., 4 Tsuga spp., 3 Pseudotsuga spp., 2 Berchemia spp., 1 Pyrus spp., 1 Bambusoideae are identified. Tsuga spp. and Pseudotsuga spp. might be used in conservation and restoration works in modern times because those species do not naturally grow in Korea. Most hanging paintings and storage boxes are made of hard pine. Also, some of are made of Tilia spp., because it represents the symbol of Buddha. Some unique kinds of trees used for wooden sculpture are identified, such as Juniperus spp. and Berchemia spp. Authentic conservation and restoration works could be carried out with this data-base.

Fungi were isolated from mural painting in tomb no.6 at songsan-ri, Gong-ju. Antifungal susceptibility of essential oils extracted from natural medicine was tested and it confirmed applicability for mural painting in tombs. 26 species of fungi collected from air-borne and wall surfaces were identified to 15 species of Ascomycetes, 2 species of Zygomycetes, 1 of Basidiomycetes. Wheat starch and gelatin degradability were evaluated as isolated fungi. SY-18, SY-23, SY-25 showed high degradability of wheat starch. SY-18, SY-21, SY-23 were decomposed into gelatin. Biochemical characteristics of decomposing fungi to wheat starch glue and cowhide glue were analyzed by using ${\alpha}-amylase$ and gelatinase activity. An Antifungal test was conducted in Anethole and Eugenol. Anethole and Eugenol mixture(1:2) showed high antifungal susceptibility. Natural adhesives help microbial growth and can cause structural damage in mural painting. The expectation of this study is the possibility to control microbial growth in wall painting using natural essential oils. It can be used as a data for conservation method to control microbial damages.
