Since Korea and Japan established diplomatic relationship, Relationship between Korea and Japan has not been easygoing. There are two most explosive, and noticeable ones among topics which have affected the relationship ; Dokdo and Historical Distortion. Without these issues, relationship between two countries will take a turn for the better. However, unfortunately, it seems that it is almost never going to happen. There is the Japanese conservative right-wing who has an influence on those two issues. The right-wing takes regard getting negative view or finding out dark past as an action from Self-torture view of history, and tries to dilute the Japanese sense of guilt on past invasions to neighbor countries. Moreover, to become a "normal country", they are trying to revise Constitution of the Japan so that Japan can possess the military and re-arm, dispatch troops abroad, and get the right to break the war. In other words, they expect Japan to become a powerful nation with great influence on Asia and world, as the period in which Japan conquered Korean peninsula, China, and South-Eastern nations. Japan still harbours secret romanticism for bygone days of imperialist glory. That is why neighbors want to never make the painful history happen again. In order to deal with this effort, most of all, it is required to assert better argument with a careful, thorough analysis on Japanese opinion about Dokdo. There might be a hidden card which can be accepted in the international society considering Japanese persistent effort to make Dokdo disputed area, and that is why we have to know that it is. In addition, it is needed to secure a high-quality professional manpower because the issues of Dokdo and Historical Distortion are primarily the matter of logic and references. The professional manpower should have open-minded to break down walls of their own majors. We have to introduce our achievements and stances to the international society vigorously. As a definite way to solve these problems, we have to develop national power. We have to possess naval forces and coast guard to protect our territory and Koreans overseas. There are not many options Korea can do to Japan, except protesting denunciation, and pressing a joint efforts. Most of the suggestions stated before are what have to be conducted domestically. It is a miserable condition, because two problems are Japanese domestic issues, but they become international issues and we have to seek a solution for ourselves.

The purpose of this study is to understand the Tecktonik culture and fashion, and to compare its features in Korea and France. Unlike prior studies which mainly dealt with subcultures in the U. S. and the U. K., this study paid attention to the condition of Korea. Tecktonik is a dance and music craze that originated in France in 2000, and spread worldwide via the Internet. The main features of Tecktonik fashion are slim fit, vivid colors, and high-top sneakers, which represent current fashion and culture trends, and express the feeling of Tecktonik music and dance. Compared to France, Korean Tecktonik fashion emphasizes sexual attraction of women with short skirt, while men are conservative about mohican hairstyle and dark make-up. In France, Tecktonik has become a sound social amusement, while in Korea it has been used for advertisements or entertainer's fashion style. The subcultural characteristics of Tecktonik were identified as playfulness, the active use of digital media, and high commercial value. In France where Tecktonik is for participating in a joyful dance, playfulness is prominent, and in Korea where Tecktonik acts as a visual entertainment, commercial value is outstanding. It has made differences in Tecktonik fashion of the two countries.

In current printer industry, four or more colorants are added for color gamut extension because the gamut of printer is smaller than other devices. However, these additional colorants make a redundancy problem that several combinations of colorants reproduced same color stimulus in colorimetric inverse characterization process. Thus, we propose a method of colorimetric inverse characterization using color correlation between colorant's amount. First, for analyzing the combination of colorants which represent the same color stimulus, we estimate the color stimulus for all combination of colorants by Cellular Yule-Nielsen Spectral Neugebauer printer model. The combination of colorants which has higher color correlation factor comparing combinations of colorant around itself in color space is selected. It can reduced the color difference from the tetrahedral interpolation process which is estimation of the output value(colorants combination) for arbitrary input(color stimulus). The selected combinations of colorants and their color stimulus are stored to the lookup table. In experiment, the CMYKGO printer was used. As a result, the dark region of color gamut was extended and the color tone was more naturally represented.

Culture condition for callus formation and plant regeneration were optimized by the selection of explants and the manipulation of hormonal combination in the culture medium. The calli induced from seed, cotyledon, hypocotyl and mesophyll segments were more vigorously proliferated under dark condition than those under continuous light condition. Hypocotyl-and cotyledon-derived calli were more regenerative as compared with those of seed and mesophyll. Callus formation from hypocotyl and cotyledonary explants was enhanced on MS medium with 1.0 mg/${\ell}$ 2, 4-D and 0.1 to 0.5 mg/${\ell}$ kinetin or BAP. The combination of 0.1 mg/${\ell}$ NAA and 2.0 to 4.0 mg/${\ell}$ kinetin was the most effective for shoot regeneration from the callus. The maximum frequency (24.0%) of shoot regeneration was obtained from the hypocotyl-derived callus transferred to MS medium supplemented with 0.1mg/${\ell}$ NAA and 4.0 mg/${\ell}$ kinetin. The capacities for callus, root and shoot formation from cotyledon and hypocotyl explants were remarkably different among cultivars of B. napus tested. The calli induced from hypocotyl produced more shoots than those from cotyledon.

This study presents an eco-friendly persimmon drying system to satisfy consumer preferences and provide a popular food for both the domestic and international markets. The most effective antimicrobial compounds were developed from a combination of plant extracts (18.18% clove buds, 9.90% cinnamon, 9.09% licorice, 4.55% cnidium, 4.55% seed of grapefruit, and 54.54% apple vinegar). The dried persimmons were evaluated as regards their moisture and sugar content, weight, hardness, and color value. During the drying process, the overall moisture content of the persimmons increased, along with the sugar content. The hardness was almost the same for each region and decreased on an average of 0.5~0.86 after 6 weeks. As regards the chromaticity, ${\Delta}E$ decreased during the drying process, while L-value became darker and a-value showed a dark red color over time.

With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

Mercury Iodide as good sensitivity at radiation and has an easy peculiarity that operates at low voltage for other photoconductors(a-Se, a-Si, Ge, etc) Based on this characteristic, we studied about an efficiency of the digital x-ray detector in acccordance with the thickness of photoconductor. To solve the problem that is difficult to make a large area film using PVD(Physical Vapor Deposition)method, we used a PIB(Particle In Binder)method. To make a binder paste, we used a PVB(Polyvinylbutyral) as a binder and a DGME(Diethylene Glycol Monobutyl Ether), DGMEA(Diethylene Glycol Monobutyl Ether Acetate) as a solvent. Using this binder paste, we made a polycrystal mercury iodide film that has an each thickness. To evaluate the electrical properties of this films, we measured a darkcurrent, sensitivity and SNR(Signal to Noise Ratio). Mercury iodide film of the 200um thickness has good electrical properties as a result of the measurement. From this result there is a good chance that replace the existing a-Se(Amnorphous seleinum; a-se) with the mercury iodide.

Intact seeds of burcucumber (Sicyos angulatus L.) are not nearly germinated so that the farmers remove their arils before sowing. The study was carried out to measure the effort of aging, chilling, washing, chemical treatment, drying, and their sequential treatments on the germination of ones with arils and the seedling emergence. The seeds extruding over 1mm of their radicles and the seedlings with fully expanded cotyledons were counted daily for calculating the germination and the seedling emergence rates. Seedcoat softening using 10% NaOH solution somewhat enhanced their germination rate of the intact seeds harvested in the current year, but aging treatment done on 6 days at $45^{\circ}C$ after NaOH treatment increased the germination rate more than only NaOH treatment. A day washing after the NaOH treatment and a day chilling after the washing increasingly elevated the rates as well. Irrigation of 0.2% $\textrm{KNO}_3$ solution, moreover, showed the greatest germination rate of the priming treatments done during all the 7 day chilling. Drying the seeds after the combined treatment of chilling and priming more inclined the germination rate than nondrying ones, but red light treated during 24 hour desiccation was more effective in the germination rate increment than dark condition. The seeds done the sequential treatments of aging, NaOH, washing, combining chilling and priming and drying under red light illumination were germinated up to 80% but seedlings were emerged to 60%, lower than ones removed their arils.

Ramyon(deep fat fried instant noodle with palm oil) preserved in sunlight, room temp. ($20{\pm}5^{\circ}C$), incubator ($30{\pm}2^{\circ}C$) and corrugated fiber board box to investigate the oxidative changes of the Ramyon lipids. In the study, changes in acid value, peroxide value, carbonyl value, TBA value, fatty acid composition, iodine value and panel test were determined with the lipids extracted from the Ramyon samples in intervals for a period of 20 weeks. Acid value, peroxide value, carbonyl value and TBA value of the Ramyon lipid were increased slightly during the storage in aluminum foil package in the corrugated fiber board box in the dark room. They did not appear the oxidative rancid odor at the end of 20 weeks storage. Acid value, peroxide value, carbonyl value and TBA value of the samples under room temp., incubator slightly during storage, while a sharp increase of those values were noticed with the samples of sunlight. Especially, the TBA value of the Ramyon lipid under sunlight markedly increased within 14 weeks and then decreased. Oxidative rancid odor appeared at the end of 10 weeks storage under sunlight, while it took 18 weeks with the sample stored under room temp. and incubator. During the storage under incubator and sunlight for 18 weeks, the content of oleic, linoleic acid decreased, while palmitic and stearic acid increased. However, only small changes were noticed in iodine value of the samples.

We developed low light CCD imaging system using thermoelectric cooling method collaboration with a company to design a commercial model. It consists of Kodak KAF-0401E(768$\times$512 pixels) CCD chip, thermoelectric module manufactured by Thermotek. This TEC system can reach an operative temperature of $-25^{\circ}C$. We employed an Uniblitz VS25s shutter and it has capability a minimum exposure time 80ms. The system components are an interface card using a Korea Astronomy Observatory (hereafter KAO) ISA bus controller, image acquisition with AD9816 chip, that is 12bit video processor. The performance test with this imaging system showed good operation within the initial specification of our design. It shows a dark current less than 0.4e-/pixel/sec at a temperature of $-10^{\circ}C$, a linearity 99.9$\pm$0.1%, gain 4.24e-/adu, and system noise is 25.3e-(rms). For low temperature CCD operation, we designed a TEC, which uses a one-stage peltier module and forced air heat exchanger. This TEC imaging system enables accurate photometry($\pm$0.01mag) even though the CCD is not at 'conventional' cryogenic temperatures(140k). The system can be a useful instrument for any other imaging applications. Finally, with this system, we obtained several images of astronomical objects for system performance tests.
