  • We investigate the immobilization of trypsin on chitosan nonwoven using glutaraldehyde (GA). The conditions for trypsin on chitosan nonwoven and GA cross-linking were optimized depending on different conditions. The order of GA cross-linking was determined by the activity of immobilized trypsin. The characteristics of chitosan nonwoven were examined by Fourier-transform infrared (FT-IR) and surface morphology analyses (SEM). Results showed that the optimal treatment conditions for trypsin on chitosan nonwoven were as follows: pH 8.5; temperature $37^{\circ}C$; trypsin concentration 15% (o.w.f); and treatment time 60 min. Those for GA cross-linking were: pH 10.0; GA concentration 3% (v/v); and treatment time 120 min. FT-IR analysis showed that GA was cross-linked on chitosan nonwoven. The SEM analysis also showed that trypsin was immobilized on chitosan nonwoven.

  • This study investigated difference of product interest and its relation to consumers' innate innovativeness according to gender as well as compared the perceptive construct of products between male and female consumers. A survey involving male and female college students was conducted in the Daegu and Gyeongbuk areas in December 2013. Subsequently, 400 responses were analyzed using descriptive statistics, correlations, independent sample t-test, reliability analysis, ANCOVA, and multidimensional scaling. Among 45 products, male respondents showed a significantly high degree of interest over 12 categories such as watches, desktop computers, cars, sports products, and video games compared to females. The female sample showed a significantly high degree of interest for 29 product categories such as clothing, movies, skin care shops, cosmetics, eating-out, teeth whitening, coffee, cameras, and performances compared to males. Innovative male consumers were interested in traveling, movies, clothing, eating-out, running shoes, and wallets; however, female consumers' innovativeness was significantly related to previously determined items of interest. Two dimensions explaining the male consumers' products perception construct were 'hard versus soft' and 'usual versus special'. Instead, female consumers' were 'special versus usual' and 'expressive versus functional'.

  • This study was investigation of the change of fine structure of hemp cellulose at different growing stages. The samples collected about every eight day were divided into seven groups based on plants height, then they were numbered from 1 to 7 in the order of their height. For this, the degree of crystallinity, orientation and crystallite size were measured by wide angle X-ray diffraction method. The results of this experiment were summerized as follows ; 1) The degree of crystallinity was increased by growth of hemp celtilose to be maximum in sample 5$\~$6. At this stage, the stability of crystals was showed in good states. In addition to, crystallinity index by Segal, Turley and area method showed same tendency as Ruland's. 2) The change of orientation was gradually increased by growth of hemp cellulose. This result was correlated with the degree of crystallinity. Therefore, the change of orientation depend on the degree of crystallinity. 3) On the other hand, the crystallite size was decreased by growth of hemp cellulose. But, increased after sample 4. By the way, crystallite size was interrelated with growth rate.

  • This research investigated the screen printing method for natural indigo dye on cotton fabric. We examined four types of thickening agents (arabic gum, guar gum, indalca, and CMC) based on their ability to retard the oxidation of natural indigo print paste while the paste remained on the screen frame. The results indicated that the retardation of arabic gum towards oxidation was the greatest among the four types of thickening agents. The highest K/S value of the printed cotton was observed with a dye concentration of 50g/L fermented indigo powder. The best printing results were obtained when the duration of dye efficiency was tested for the 10 minutes of the dye paste remaining on the screen with a thickening agent concentration of 26.56% that represented 530 cps viscosity. The test of colorfastness to washing and rubbing of the printed cotton resulted in grade 5, and the colorfastness to sunlight resulted in grade 4. Chinese traditional Naminwhapo printing was reproduced on cotton fabric using the natural indigo printing method derived from this study.
