Currently, most of TDIS(Train Destination Indicator System) is operated colored-LED type equipment in Korea. This current LED type TDIS equipment has not graceful display and causes passenger's fatigues because of the LED module inherent characteristics as a display light source, high power consumption, high operating and maintenance costs, and et al. To address these several, we are developed new colored-LCD type TDIS equipment. According to our developed new TDIS equipment, we can achieve high resolution and graceful color stone of information display. Thus high graded service are able to provide to passengers. In addition, LCD module decreases power consumption, and it can be used permanently by changing only backlight in comparison with conventional equipment. Therefore we can decrease the maintenance cost and extend durability-period of TDIS equipment using new equipment.

The main objectives of this study are develop an Electro-Chemical process for dyeing wastewater treatment. In this work, We are investigated to optimization of electro-chemical process condition such as pH, additives(NaCl), reaction time, current density. As a result, About 89% of color(influent 452.5 ptco. unit) was removed by Electro-Chemical process using type C $SnO_2$ electrode. This results are promising potential for dyeing wastewater treatment.

The feasibility study for the application of the removal and mineralization of Rhodamine B (RhB) was performed in a batch electrochemical reactor. The electro/UV process was consisted of DSA (dimensionally stable anode) electrode and UV-C or ozone lamp. The experimental results showed that RhB removal by the ozone lamp was higher than that of the UV-C lamp. Optimum current of the electro/UV process was 1 A. The electrochemical, UV and electro/UV process could completely degrade RhB, while a prolonged treatment was necessary to reach a high level RhB mineralization. It was observed that RhB removal in electro/UV process is similar to the sum of the UV and electrolytic decolorization. However, it was found that the COD of RhB could be degraded more efficiently by the electro/UV process (90.2 %) than the sum of the two individual oxidation processes [UV (19.7%) and electrolytic process (50.8%)]. A synergetic effect was demonstrated between the UV and electrolysis.

Currently the indication method of the traffic signal light which is established in our country displays each "red, yellow, green" using the brightness LED signal light. In this paper, one LED circular arrangement replaces the Current indication method of the traffic signal light using two color LED. Also the blinking signal function of present time uses the MCU of AVR series and it is embodied with magnification and abridgment of the circular arrangement for recognizing easily far away. The signal light indication method which is proposed will be able to substitute the signal light of 3 colors with 1 signal light with economic profit presented the reform measure of energy efficiency improvement together.

ITO thin film is generally fabricated by various. methods such as spray, CVD, evaporation, electron gun deposition, direct current electroplating, high frequency sputtering, and reactive DC sputtering. However, some problems such as peaks, bumps, large particles, and pin-holes on the surface of ITO thin film were reported, which caused the destruction of color quality, the reduction of device life time, and short-circuit. Chemical mechanical polishing (CMP) process is one of the suitable solutions which could solve the problems

This paper tries to converge computer and art by applying anamorphosis principle in drawing technique to mobile application. As comparing to current anamorphosis which shows one image at the round cup, we focus on the variability which shows several variable images at the mobile device according to the color board. The usage of the proposed algorithm is able to extended to various areas such as souvenir and public relation.

The purpose of this research is to offer basic data for the study of men's suit by investigating purchase behavior and fit of men's ready-made suit for Koran adult men. The subjects were male who aged 25∼39 and resided in Seoul, Kyunggi and Chungnam regions. The results of the research are summarized as the following : 1. Male consumers purchase suit most frequency at department, specially stores. As the consumers grow older dependency on their spouses'opinion for purchase decision increases. The standards of purchasing are stated to e design, price and color. 2. the male consumers are generally knowledgeable about the current sizing system. Yet, the knowledge is confused with the pst and present systems. 3. When the male consumers purchase, they consider mainly for the fit of th d\\body part are shoulders for the jacket and waist, hip for the pants. 4. The attitude to toward the combination of sizes for the jacket is comparatively satisfaction than pants. Specially, most negative part of jacket is the length of sleeve.

In this study, the matrix Organic Electroluminescence (OEL) device, that was consisted of R,G,B pixels. We fabricated OEL devices by side by side methode and, used organic material Alq3 as green, DCM as red and Butyl PBD as blue ETL. We investigated the characteristic of brightness and current density for matrix OEL device. As the results, each color devices has minimum about $100cd/m^{2}$ brightness and maximum luminescence was $2500cd/m^2$ in green OEL device.

As in our $20^{th}$ century, the dramatic advance of the science and medical technologies has led the advance of living standards. Even though the elderly people are increasing, the underwear for elderly women is not so various. As getting older, women's body shape is changing. But the most of underwear in the market are designed for the twenties whose body shape and proportion is generally stable. Besides, as the color and material of underwear are designed for young women, the elderly women have a poor choice of the underwear. The results of this study are listed in the following: (a) analyzing the current status of the underwear market for elderly women (b) searching what elderly take inconvenience in underwear, and (c) wearing test for search what elderly take inconvenience in brassier.

In response to the continuous changes in current consumer demands and market trends for postharvest produces, the functional application for agricultural packaging is becoming increasely significant. This paper focuses on the overview of important changes in physical and chemical status related to postharvest physiology and applications of the functional packaging materials for maintaining the freshness of fruits after harvest. During postharvest treatment and storage periods, fresh fruits undergoes the ripening process in quality attributes of the fruit such as major changes of texture, color, and flavor. Major fruit packaging technologies are concerned with correct gas permeable film and functions of ethylene removal, antimicrobial, and antifogging substances to keep the effective freshness. Application guidelines for the functional packaging in fresh produces were studied.
