    Young-A Son | KIM SUNG HOON | 2014, 26(1) | pp.1~6 | number of Cited : 4
    Abstract PDF
    We have designed and synthesized the colorimetric chemosensor through the reactions of 1,2-anthraquinone and indol-3-carboxaldehyde. Due to its well conjugated D-π-A system and the existence of NH- fragment in indole moiety, we expected that the chemosensor can detect target anions with NH- fragment in indole part of the structure. In this regard, UV-Vis absorption spectra were measured to investigate sensing properties of the probe toward different anions in DMSO. This chemosensor shows to detect fluoride anions with absorption change in intensity. These properties are mainly related to the deprotonation effect. ICT system in this molecule was also observed by the computational approach using Material Studio 4.3 package.

    Young-A Son | 2014, 26(1) | pp.7~12 | number of Cited : 1
    Abstract PDF
    Nowdays, fluorescent rhodamine chemosensors have attracted a worldwide interest due to its ability to selectively detect heavy and transition metal cations. Due to the importance in environmental and biological toxic effects, the developments of fluorescent chemosensors have been received considerable attention in recent. Especially, a rhodamine-based chemosensor probes have been proved to be useful by exhibiting the efficient “off-on” fluorescence switching toward selected metal cations. This fluorophore can undergo the transformation from non-fluorescent and colorless spirolactam derivative to fluorescent ring-open form. In this study, a new fluorescent chemosensor was synthesized using rhodamine B through two-step procedures, and its selectivity and related optical property were characterized. Selectivity and sensitivity was found toward Cu2+ guest molecules and then related optical properties of rhodamine B based fluorescent chemosensor compound were characterized using discussed. In addition, computational calculation was used to determine the HOMO/LUMO values.

    yong wan park | Kim, Eui Hwa | 조호현 | 2014, 26(1) | pp.32~38 | number of Cited : 1
    Abstract PDF
    There has been increasing demand to the eco-friendly materials such as phytoncide which is extracted to plants in the textile industry, recently. It is interesting that alginic acid sodium salt(Alg-Na) is used to eco-friendly binder for the functional capsule finishing. In this study, we made PEO/Alg-Na blend solutions of various ratio and observed the changing binding property of the blend solutions according to PEO contents through FT-IR, DSC, contact angle, peel strength, etc. The viscosity of Alg-Na/PEO blend solutions increased with increase of contents and the viscosity quickly increased with increase of PEO content in Alg-Na 5% content, specially. It is shown that the hydrogen bond peak by blend of Alg-Na and PEO found through FT-IR analysis but the peak decreased in PEO above 60% content. And the peel strength was predominant in PEO 50% ratio.

    Comparison and Evaluation of Real Industry Color(RIC) Device and Spectrophotometer for the Colors of Dyed Fabric

    빈소영 | Jin-Seok Bae | 김동권 and 4other persons | 2014, 26(1) | pp.39~44 | number of Cited : 0
    Abstract PDF
    To confirm the performance and benefit of the developed online E-commerce Real Industrial Color(RIC) device, cotton and polyester were dyed with selected 39 colors. The captured images of dyed cotton and polyester by using RIC device were compared with original samples and confirmed △E using a spectrophotometer and RIC device. Overall, visual comparison of the captured images was similar to the real dyed samples. In high concentration of dyeings, the color consistency between real samples and captured images was better than in lower color concentration of dyeings. Similarly, the result was almost the same when the developed RIC device was used since △E values of RIC device were smaller compared with spectrophotometer. In this regards, the RIC device developed up to date can be assumed that it is more influenced by the color rather than fabric materials.

    정경희 | Dae Youn Hwang | Young Jin Jung and 6other persons | 2014, 26(1) | pp.45~52 | number of Cited : 7
    Abstract PDF
    Red pine (Pinus densiflora) is widely used traditional medicine, pharmacological and nutritional values from which the phytochemical compounds are derived. The present study was aimed to examine the antibacterial effects in the absence and presence of a immature red pine cone extract against 13 microorganisms. The components in the aqueous extract from immature red pine cone were identified by GC‐MS. About 1.4% of total polyphenolic compound was measured in aqueous extract collected from immature red pine cone. Also, the high concentration of β‐phellenandrene, α‐pinene, limonene, bornyl acetate and aldehyde was detected in total ion chromatograms. Of total 13 microorganisms, 4 microorganisms including Pseudomonas aeruginosa, Vibrio cholera, Listeria monocytogenes, Klebsiella pneumonia were effectively killed by aqueous extract of immature red pine cone. The highest anti‐bacterial effect was detected in P. aeruginosa, followed by V. cholera, L. monocytogenes and K. pneumonia. In case of P. aeruginosa, the largest diameter of inhibition zone was maintained to 1/2 solution treated cells and slightly decreased at 1/4 and 1/8 solution treated cells. Also, in test used V. cholera and L. monocytogenes, the inhibition zone was strongly formed in only 1 and 1/2 solution treated cells, while K. pneumonia showed the very small diameter of inhibition zone in all concentrations. Therefore, these results suggested that the aqueous extracts of immature red pine cone should be considered as a new and potentially important anti‐bacterial substrate to effectively prevent the microbial infection and penetration.

    Hyun-Jin Jeon | Im soon yea | 정찬이 | 2014, 26(1) | pp.63~70 | number of Cited : 0
    Abstract PDF
    This study has attempted to figure out the effects of the surface heat of perm rods on hair. For this, after forming perm waves, hair damage and its causes have been investigated with a different hair bleach method. If hair was bleached immediately without shampooing after a perm using the heat of rods, great perm waves were formed. However, severe damage was found on the hair because of the heated rods. In addition, when hair was shampooed and dried after the perm, hair bleach was more effective. It has been confirmed that hair was damaged because of high temperature of the surface of the rods. In fact, the heated rods had a direct effect on hair damage. According to these results, it has been confirmed that heat-based perms can accelerate hair damage. Therefore, it is necessary to perform a study on the minimization of the heating of permanent tools.
