Along with and <1Q84> Murakami Haruki sees through human nature that fades away with time in his latest work with 'color and memory'. This is the type of character or story to read with the deployment of instrument. Costume of characters conceived in the expansion of the body, the inner expression of personal notes. To others what you want to look, how they formed on the body, with a range of social, if you are claiming a statement. To form the body by forming self-practice is that there becomes. This paper the inside of the characters and the apparent strong interest in the set, costume characters, especially characters were recognized as representing the device of novel. Work directly in the results, or is described as a symbolic system of the body and clothing that embodies the meaning of the symbol you want to the structure of the exchange.

The characteristics and stability of pigments produced by Monascus anka in a jar fermenter were examined The pigments produced by the mold were fractionated into four pigments, i.e., extracellular red pigment(ERP) extracellular yellow Pigment(EYP), intracellular red pigment(IRP) and intracellular yellow pigment(IYP) by the solvent fractionation method. These pigments showed characteristic absorption spectrum indicating that they were composed of different components of pigments. Each of these four pigments separated from Monascus anka were stable under ultraviolet light, fluorescent light and in dark conditions, but their color was faded rapidly under sun light. They were also very stable against temperature below 8$0^{\circ}C$, above which temperature the stability of the Pigments was decreased rapidly. Among the eight organic acids tested, tartaric and citric acids were found to be detrimental against the Monascus anka Pigments. And Cu$^{2+}$ ion showed the most deleterious effect on the color change of the pigments.s.

To elucidate the cause of Pyropia yezoensis discoloration, the characteristics of an aquaculture environment, as well as the morphology and cell structure of P. yezoensis thallus were examined from 2011 to 2014 in aquaculture farms of the Jeonbuk province. P. yezoensis discoloration did not occur in aquaculture farms at Gaeyado located in the Geum River Estuary but occurred in aquaculture farms of Seonyudo, Munyeodo, Biando, and Docheongri near the Saemangeum embankment in November 2011 and April and November 2014. The injured leaves showed discoloration and intracellular vacuole hypertrophy. During the study period, discoloration occurred at concentrations of dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) below 5μM and 0.4μM, respectively. As a result, Pyropia discoloration was determined by low concentrations of DIN and DIP. DIN deficiency affects the early stage and low DIP concentration affects the end stage of aquaculture.

Bis(dithiobenzil) metal complex, used as functional NIR absorbing dye and photostabilizer, was synthesized using bezoin and anisoin as intermediate compounds. And squarylium, a charge generation material, was synthesized to find its photostability effect. The structure of the product was determined by $^1H-NMR$ and FT-IR and the thermal property was analyzed by DSC and TGA. Optical property and photostability were determined by UV-Vis-NIR spectroscopy. High absorbance was obtained in the NIR range and maximum absorbing wavelength was shifted depending on the nature and position of substituent in the bis(dithiobenzil) metal complex. The photofading effect of squarylium decreased by the addition of bis(dithiobenzil) metal complex.

Adolescent volunteer, a kind of experience activity, can have positive influence on the improvements of sound personality, community ownership, and leadership living skill ability. However, its purpose is today declining because it tends to be only used for the adolescent university admission. This study investigates the impacts of adolescents' volunteer participation motivation(selfish and selfless) on leadership living skill ability(human relationship skill, group activity skill, learning skill, and self-understanding skill) and satisfaction. The study conducted a survey and utilized 222 questionnaires to examine these relationships. The results are as follows. First, selfless participation motivation had significant impacts on four leadership living skill abilities and satisfaction. Second, selfish participation motivation had no significance on four leadership living skill abilities, but had negative significance on satisfaction.

When a light is projected upon a material, part of its radiant energy is absorbed and the rest is reflected or transmitted according to the nature of the material. The molecules of the substance absorbing a light obtains the radiant energy to make thermal reactions or photochemical reactions. Specially, photochemical reactions by ultraviolet(UV) radiation brings about photochemical degradation such as color change. Because the photochemical damage brings about a devaluation of material and once damaged, it is irretrievable, it is necessary to minimize the damage and conserve the native quality of a material by a protective lighting system. This paper presents the measurement and photochemical damage for UV radiation from light sources. We measured the optical radiations from artificial light sources and daylight, and we analyzed a functional relation between irradiance and UV radiation form the results.

The purpose of this study was to isolate and characterize fungal deteriogens, which induce discoloration of the cement tunnel, and calcite forming bacteria (CFBs), which have antifungal activity against fungal deteriogens. Isolation of mold, bacteria and yeast was performed using several solid media and partially identified using internal transcribed spacer (ITS); 5.8S rRNA gene sequencing and 16s rDNA sequencing. A total of 19 microbial strains were identified with the most widely distributed fungal strain being Cladospirum sphaerospermum. In addition, five bacteria derived from the tunnel were identified as CFBs. Amongst the latter, Bacillus aryabhatti KNUC205 exhibited antifungal activity against Cladospirum sphaerospermum KNUC253 and Aspergillus niger KCTC6906 as concentrated filtered supernatants.

Degradation products of the dye extracted from turmeric and the turmeric dyed textiles were examined by using GC-MS after 100 oven (OV) and $H_2O_2/UV/O_2$(PER) treatments for up to 28 days. Throughout the OV degradation times, 2-propenoic acid, 3-(2-hydroxyphenyl)- was found consistently, while isovanillin, and vanillic acid were newly detected. In 28 day PER degradation sample, feruloylmethane, 2-propenoic acid, 3-(2-hydroxyphenyl)-, benzoic acid, and vanillic acid were detected as well as isovanillin. Feruloylrnethane, and 2-propenoic acid, 3-(2-hydroxyphenyl)- were detected from the degraded fabric samples. With the absence of curcuminoids in the GC-MS result, the decreasing pattern of 2-propenoic acid, 3-(2-hydrokyphenyl)- reflect the degradation of curcuminoids in turmeric extraction with the progression of OV degradation times. It is suggested that isovanillin, feruloylmethane, 2-propenoic acid,3-(2-hydroxyphenyl)-, and vanillic acid are the probable fingerprint products for determining the turmeric dye from the badly faded archaeological textiles.

Following advances in technology and with the growing need for renewable energy, fluorescent and halogen lamps are being replaced by LED lighting in museum systems. This paper researched the setting of standards for the diverse lighting systems in addition to the LED lighting that are expected to be introduced in museums in the future. Contrary to previous belief, LEDs were shown to only barely emit in the ultraviolet region, but the visible rays were confirmed to produce discoloration depending on illuminance-hours. When the color change by LED lamps at the color temperature of 2800K, or warm white, was compared with 5500K, or white, the emission spectrum analysis confirmed that the blue spike increased at a higher color temperature and caused more discoloration. This suggests that in addition to illumination, color temperature should be considered by including the emission spectrum when museums set lighting environment standards.

Here is an introduction of the conservation and making process of Seodae(Rank Belt with A Rhinoceros' Horn) of the Chuncheon National Museum. The seodae has a structure composed of wrapping fabric around a leather frame and decorated with ttidon(an ornament) made of a rhinoceros' horn and a metal frame. The adhesion between leather was weak and separation was taking place, parts of the horn were missing and the fabric was discoloring. Also the metal frame and the metal wire attaching ttidon were severly corroded. Nondestructive analysis was carried out by using a portable x-ray fluorescence spectroscopy to analyze the components of the metal parts. Conservation was carried out by dismantling parts and carrying out conservation process of each one according to material, then the parts were put back together.
