  • Formaldehyde(HCHO) may have a damage effect on Korean traditional textiles, because concentration is high and occurrence frequency is frequent at the exhibition room and storage area. Total 20 specimens were prepared using 4 different materials (silk, cotton, ramie, hemp) after dyeing with 5 colors (undyed, red, yellow, blue, black). The specimens were exposed to HCHO gas in the test chamber. The gas acceleration test was conducted to identify the deterioration of Korean traditional textiles according to HCHO concentration(0.5, 1, 10, 100, 500ppm), to temperature-humidity condition at HCHO 500ppm, and deterioration conditions at HCHO 500ppm. Optical, chemical, and physical evaluation was carried out after the exposure. The results, color difference, grey scale rating, formate($HCO_2{^-}$) of some textiles increased at 500ppm, while pH decreased at 500ppm. Also, color difference, grey scale rating, formate($HCO_2{^-}$) of some textiles increased double damage at high temperatures & humidity, high humidity condition. But, damages of accelerated degradation textiles were slight, because of degradation degree and degradation products. The results suggest that determined the damage to the korean traditional textile, damage level, damage-weighted condition, damage to accelerated degradation textiles. In addition, formaldehyde damaged to yellowing of red textiles, bleaching of accelerated degradation textiles, formic acid damaged to bleaching of total 20 specimens.

  • The MC1R (Melanocortin 1 receptor) gene has been known as a causative gene of the coat colors in mammals and responsible for the E (Extension) locus which has three alleles ($E^D$, $E^+$, e) that determines coat colors. The dominant allele $E^D$ produces black or brown colors due to the missense mutation and the recessive e allele has frameshift mutation which shows red or yellow coat colors. Whereas the wild type $E^+$ produces variety of colors due to the interaction with A (Agouti) locus. In this study, PCR-RFLP was performed using two restriction enzymes (BsrF I and MspA1 I) in order to obtain MC1R genotypes in Korean brindle cattle and black cattle. The results showed that all of the animals have the $E^+$ alleles, indicating the $E^+$ allele might related with black coat colors. Later on, the experiments expanded to the 260 Korean candidate bulls whether these animals have the same $E^+$ allele. Among 260 samples investigated, 5% (13/260) of the animals had $E^+$e genotypes, indicating the $E^+$ allele is also present in the candidate bulls in a low frequency. Even though we expected that A locus also affect the black coat color in cattle, all the black coat color animals (brindle and black) have $E^+$ alleles in this study. Therefore, the genotyping of the MC1R gene in candidate bulls will recommended be applied for eliminating of black coat colors in Hanwoo population, if the farmers need to have the brown coat colors only.

  • This study investigated the effect of different electrical stunning methods on pH, water holding capacity(WHC), cooking loss(CL), meat color and blood spot rate in broilers. One-hundred and forty broiler chickens were slaughtered by 50, 65 and 90 voltage with the same electrical frequency(255 Hz) and stunning time(5 sec) in commercial abattoir. The ultimate pH of leg muscle and WHC of breast muscle decreased with increasing the stunning voltage. However, there were no significant differences in ultimate pH, WHC and CL of breast muscle, and ultimate pH of leg muscle. Lightness(L*) and yellowness(b*) values of leg muscle stunned with 90V, 255 Hz, 5 sec were higher than those stunned with 50V, 255 Hz for 5 sec(p<0.05). But there were no significant differences in color value on skin, breast and wing muscle. Our experiments showed that change of stunning voltage affected some broiler meat quality parameters. However, further research is necessary to examine the effects of stunning condition on broiler meat quality.

  • Thermal stability of the major color component, cyanidin 3-glucoside, isolated from Korean pigmented rice (Oryza sativa var. Suwon 415) were investigated to explore possible application of value-added natural colors as food additives. The anthocyanin showed red and blue color with maximum absorption peaks at 511 nm and 572 nm in acidic (pH 2.0) and alkaline (pH 9.0) buffer solutions, respectively, and the thermal degradation reactions were carried out with different temperature ranges at $50{\sim}95^{\circ}C$. Degree of degradation was determined with UV/Vis spectra which indicate characteristic absorption patterns with sharp isosbestic points at 350 nm (pH 2.0), and 275, 310, and 405 nm (pH 9.0). Thus the reaction follows simple first-order kinetics. The anthocyanin was very stable against heat at acidic pH and relatively stable at alkaline pH with half-life values of 50.3 hr and 0.6 hr at $70^{\circ}C$, respectively. The activation energies and Arrhenius frequency factors of the pigment were 26.9 kcal $mol^{-1}\;and\;6.0{\times}10^{11}\;s^{-1}$, at pH 2.0, and 15.2 kcal $mol^{-1}\;and\;1.4{\times}10^{6}\;s^{-1}$, pH 9.0, and respectively.

  • The purpose of this study is to investigate the changes of modern Korean men's pants design from 1962 to 1998 by reviewing fashion magazine advertisements and pictorials. For theoretical study, the characteristics and the importance of apparel advertisements and the changes of modern Korean men's fashion trend were reviewed. For sample selection, first, 932 pictorials of men';s wear designs from Joongang Magazine, Shin Dong-A, Bokjangwolbo, Meot, Men's Life, WWD, and SFAA's photograph album, published from 1962 to 1998 were selected and then excluded some samples that could not clearly identify the pants design. Content analysis method was used to analyze the content of magazines and pictorials. The final samples are classified into pattern, color, length, silhouette, and existence or non-existence of turn-up. Frequency and $x^2$-test were conducted using a SAS statistics package to analyse the data. The results were as follows. ; (1) Solid pattern was the most prevailed throughout the last four decades and followed by stripe, check, the others, abstract, dot and floral. There is no significant difference in the type of men's pants pattern between each decade. (2) It showed a significant difference in colors of men's pants between decades. The colors in men's wear are divided into nine categories and the order of occurrence are as follows; multi-color is the most frequently shown and followed by brown, gray, blue, black, green, pink, yellow, and red. More various colors appeared over the period, however, multi color was the most popular in all decades but in the 60s. (3) Full length of pants style occupied more than 96% throughout all four decades. Due to the popularity of sports wear in men's fashion during the 90s, the shorts style appeared not only in sports wear and casual wear but also in suit style. (4) There is a significant difference in silhouette of men's pants between decades. The silhouette of men's pants were divided into four types and their order of occurrence are as follows; basic, baggy, fitted, and loose silhouette. Basic silhouette was the most prevailed throughout the whole four decades. (5) A significant difference was shown in the existence or non-existence of turn-up of men's pants between decades. Non-existence of turn-up of men's pants was the most prevailed throughout the whole four decades.

  • This study was conducted to grasp distribution of native plants in flower market and uses of native plants in floral decoration. This study was investigated native plants sold in flower market(2017.01-2017.12) and their monthly sales. Also, this study analyzed the use of native plants, frequency of native plants classified by form and color of native plants used for floral decoration in flower magazines 'Fleur' and 'The Flower'. Among 172 species distributed cut-flower, native plants in Korea flower market are only 24 species(14.0%). Number of filler flower(15 species) is more than other forms. Native plants used in 'Fleur' and 'The Flower' were 14 species(10.2%) and 17 species(9.6%), it is meaning that native plants were less used than foreign plants. The number of filler flower was the highest in both magazines, but form flower(299 works) in 'Fleur' and mass flower(571 works) in 'The Flower' are used most frequently. According to color analysis of native plants used for floral decoration, P(purple), PB(navy) and RP(reddish purple) were 57% of the total. It can be increased native plants uses in flower decoration with developing form and mass flower considering color preference.

  • The objectives of this study were to investigate physiological and psychological responses to the rustling sound of Korean traditional silk fabrics and to figure out objective measurements such as sound parameters and mechanical properties determining the human responses. Five different traditional silk fabrics were selected by cluster analysis and their sound characteristics were observed in terms of FFT spectra and some calculated sound parameters including level pressure of total sound (LPT), Zwicker's psychoacoustic parameters - loudness(Z), sharpness(Z), roughness(Z), and fluctuation strength(Z), and sound color factors such as ${\Delta}L\;and\;{\Delta}f$. As physiological signals, the ratio of low frequency to high frequency (LF/HF) from the power spectrum of heart rate variability, pulse volume (PV), heart rate (HR), and skin conductance level (SCL) evoked by the fabric sounds were measured from thirty participants. Also, seven aspects of psychological state including softness, loudness, sharpness, roughness, clearness, highness, and pleasantness were evaluated when each sound was presented. The traditional silk fabric sounds were likely to be felt as soft and pleasant rather than clear and high, which seemed to evoke less change of both LF/HF and SCL indicating a negative sensation than other fabrics previously reported. As fluctuation strength(Z) were higher and bending rigidity (B) values lower, the fabrics tended to be perceived as sounding softer, which resulted in increase of PV changes. The higher LPT was concerned with higher rating for subjective loudness so that HR was more increased. Also, compression linearity (LC) affected subjective pleasantness positively, which caused less changes of HR. Therefore, we concluded that such objective measurements as LPT, fluctuation strength(Z), bending rigidity (B), and compression linearity (LC) were significant factors affecting physiological and psychological responses to the sounds of Korean traditional silk fabrics.

  • The purpose of this study was to explore global consumer behavior with fashion products, Korean fashion products, and Korean traditional fashion products (i.e., Han-Bok). Clothing selection criteria for fashion products and Korean fashion products were included as major constructs far the comparison among global consumers based on their nationality. Other consumer behavior variables were shopping place, buying frequency, purchase experience/plan, preferred brand, purchase items, information source, purchasing usage, and the product evaluation of Hanbok. A convenience sample of 236 global consumers was selected for this study. A questionnaire was pilot tested, and the revised questionnaire was used for the interview survey. Descriptive statistics and ANOVA were used for data analysis. Various nationality were existed such as Europe, North America, Japan, China, South East Asia. The results indicated that the most important criteria for fashion buying were design, fit, and size in order. Fit, size, and color item from buying criteria were significantly different among global consumers by nationality. Country of origin was found as less important factor among global consumers. Department store was most favorable shopping place, and once a month is the most mentioned category in buying frequency. Preferred brands were Levi's, Polo, Gucci, and Prada, etc. Secondly, regarding the evaluation of Korean fashion products, textile quality was highly evaluated. Significant difference except design/style category were existed among global consumers by nationality. Thirdly, regarding the evaluation of Hanbok, the product evaluation of Hanbok highly represented as special event clothing, unique image, beautiful details and oriental beauty in order. Significant difference in good quality of textiles, oriental beauty, coordination with good colors and fabrics, beautiful details and unique style and design were existed among global consumers by nationality. Managerial implications were discussed.
