Materials and techniques used for two portraits (Jo-nyeon Lee and S ung-in Lee) of the Lee family from Seongju enshrined in Seongsan temple were scientifically analyzed, and based on the data, an optimal replica restoration method was designed. According to the expression technique investigation, both portraits were expressed mainly in line drawing, but there were differences in shoes, pupils, the color expression of flesh, overpainting, and traces of reinforcement. Pigment analysis revealed that a mixture of cinnabar and minium, organic pigment, azurite, malachite, lead white, and yellow pigment were used in common. In the case of Sung-in Lee's portrait, seokganju and atacamite were also used. In addition, comparison with the contemporaneous portraits of gentry showed that the portrait style at the time was found in the two portraits, but the singularity was modified differently there. Based on the scientific analysis, it was decided to replicate the old color restoration for Jo-nyeon Lee's portrait while for Sung-in Lee's portrait, it was decided to replicate the phenomenon. Detailed coloring techniques were presented by supplementing the expression techniques that are difficult to confirm visually using scientific data. In addition, by measuring the chromaticity of representative positions in the portrait for each color and presenting the color reference value calculated as the average value, the current color of the artifact can be replicated and restored based on the objective data as much as possible.

Photography is frequently associated with the death because it seems to remind us of our own mortality by representing the dead people. The indexical character of photography reinforces this association. Photography is used in many ceremonial activities and medias to represent death. Five types of death photography can be differentiated: funeral portrait, post-mortem photography, conflict and disaster photography, death penalty photography, anatomic and forensic photography. These death photographies serve for four individual and social purposes: mourning and remembrance, resistance and struggle, rule and domination, disclosure and accusation.

OPNW, which takes charge of the outer neutral wire role and the inner optical network role, was developed at the first time among nation and substituted the neutral wire of distribution line between electric power substation and neighboring station. This paper refers to results about its optical character measured periodically, and examines closely whether the unique matter will be occurred or not about the role of neutral wire during more than one year. Also, established OPNW became a new chance to distribution facility's working by establishing remote portrait supervisory system and doing remote supervisory about essential equipment of distribution line.

A drawing technique which use only fine curves and dashed lines is widely adopted in banknotes and post stamps printing. Engraving of the curves and lines are traditionally performed by hand skill which provides low productivity in printing. As an effort for higher productivity and quality, a drawing automation method which can easily produce NC codes and drawings for a mechanical or chemical engraving is proposed. An initial work shows that it is possible to draw a portrait by contolling the width and length of predetermined fine lines according to the gray scale at the end points of each line. User interface functions of a commercial CAD system are heavily employed to exploit the presented method.

Three hundred years ago, the fractional differential equation that is one of concept of fractional calculus released. Now, many researchers continue to try best effort applying into the control engineering, mathematics and physics. In this paper, the dynamics equation which is represented by Van der Pol, represent integer order and fractional order that having real order. Then this paper performs the comparisons between integer and real order as time series and phase portrait according to variation of parameter value for real order.

Love which is one of the emotional of mankind, has been studied in sociology and psychology as a matter of grate concern. In this paper we propose a modified romantic behaviors by using basic the love equation of Romeo and Juliet. We represent the behaviors using time series and phase portrait when we vary the parameter in the modified love equation. Also we analyze the behavior's relation by using time series and phase portraits when external force applied as the third person between Romeo and Juliet.

The culture and society environment plays major role in the development of Fashion and now in the 21st century, interest in Fashion is getting increased along with the rapid progress of advanced media development and information surge. Now it s the time to extend visual efficiency not only transmitting fashion image but also develop a creative product that satisfy the demander s needs. Currently it is very hard to express our subjective Korean "nationalism" in the Fashion since the various expression skill using western fashion illustration are dominant in our society. I have classified two components, fashion illustration and Korean painting in the theoretical circumstance. In fashion illustration circumstance, I examined the concept, usage, expression skill and history referring to historical documents. In Korean painting section, I considered coloring portrait concept, pattern, history, concept, and feature of the four gentlemanly plants. including the basic material of Korean-paper, Writing- Brush, Ink-Stone, Traditional-ink and also the history of itself. I have designed 8 products applying the concept of plum blossoms, orchids, chrysanthemums and bamboos that represent the most important part of the four gentlemanly plants, and also the expression skill of Korean coloring portrait.rait.

The study was designed to review the changes in designs and the manufacturing methods of french hood, one of the headdresses which play an important role in showing the appearance of costume, to understand design expression techniques through manufacturing of the head dress of the western costumes, and to provide materials to exert creativity for new designs. Based on literature review and portrait study, 1 manufactured a frenchhood. I set the study cope as from the late 15 century when frenchhood was used for the first time, to the mid 16 century. For the frenchhood selected, 1 examined the hair style, the characteristics of the french hood, and the pattern first, and proceeded to manufacturing. 1 used velvet and silk for the textile as explained in the literature. And, 1 purchased such similar ornaments as shown in the pictures, making the color so similar to the original to the most. Dimensions in manufacturing were those In the literature, since the study is focusing on the reproduction of the features of the portraits. Dimensions of detailed decoration were measured using the ratio of the headdress in the portraits.
