The opto-functional materials have been developed as a promising research topic toward the end uses for optical materials and applications. The attractive area in this part was the design of sensor molecules for detecting harmful environmental factors. These harmful factors impart undesired effects on wide range of chemical and biological phenomenon. In this context, many researchers have studied luminescence chemosensor materials. These sensor molecules showed optical signals such as color or fluorescence change by detecting harmful environmental factors. In this study, the novel fluorescence chemosensor 1 has been designed and synthesized through reaction of rhodamine 6g hydrazide and 2-hydroxy-1-naphthaldehyde. The chemosensor 1 had been analyzed by UV-Vis and fluorescence spectrophotometer. We found that this chemosensor 1 has 'off-on' and dual type sensing properties toward $Cu^{2+}$ and $Mg^{2+}$.

Epoxy resins are currently one of the most widely used thermoset polymers. Applications on epoxy-based materials range from common to structural adhesives as well as to matrix materials for high performance composites. The outstanding versatility of this resin can be related to the reactivity of the epoxy group, which can be opened by a large number of different chemical compounds, such a aliphatic and aromatic amines, anhydrides and poly-amides.

For the common drier and heaters, the heat gradually transfers from exterior to interior in the materials, as it generally adopts radiant or/and convection heat. However, by using microwave, both the interior and exterior of fiber materials can be evenly heated simultaneously. (omitted)

Fragrant microcapsules were prepared by in situ polymerization using urea-formaldehyde prepolymer. Lemon oil and migrin oil as susceptible materials were used. The diameter and distribution of the microcapsule were controlled by several factors, such as wall material, core material content, emulsion agent and stirring speed, respectively. Susceptible cotton fabrics with fragrant release functionality were successfully produced by using microcapsule containing fragrant materials.

In this study, for textile use, the octadecane of phase change materials(PCM) was encapsulated in several micro-diameter shell which prevents leakage of the material during its liquid phase. Microencapsulated PCM(PM) was prepared with the different weight ratio of core material to wall material and by interfacial polymerization methods using polyurea as shell material. Phase stability for O/W emulsion of PCM and PVA aq. (PE) was evaluated by Turbiscan Lab. The capsule formation win identified using FT-IR. Physical properties of microcapsules including diameter, particle distribution, morphology were investigated. Thermal transport properties of suede treated with PM(SPM) were determined by KES-F7 system.

Recently, computational calculation of molecular energy potentials and electrochemical reduction/oxidation behaviors are of very importance in view point of prediction of dye's properties such as energy levels and bandgaps of absorption. This can be influenced by their different constituents or substituents in chromogen molecules. Structural conformations and properties with computational modeling calculation are numerically simulated, which are fully or partly based on fundamental laws of physics. In addition, cyclic voltammetric measurement was used to obtain the experimental redox potential values, which were compared to the computed simulation values.

Nowadays, firms face the challenge of how to balance between the environmental request and business profit under the circumstances of being eco-friendly and sustainable. The purpose of this study was to investigate the effects of business environmental factors on the 4p mix of an eco-friendly textile in the textile fashion firms. This research was conducted by a questionnaire method, in which the questionnaires were distributed to the textile fashion firms. Of the returned questionnaires, one hundred of them were selected to be included in the analysis by developing descriptive statistics, factor analysis, cronbach's alpha, and regression analysis using SPSS18.0. The results of this study were as follows: There were significant effects of the firms' environmental management, organizational structure, and CEOs' environmental sensitivity in descending order of the business internal factors on the textile fashion firms' eco-friendly textile product. The factors of the firms' environmental management, organizational structure(internal factors), and legal regulation(external factor), in descending order, significantly affected the promotion of the eco-friendly textile. The factor of firms' environmental management (internal factor) significantly affected the distribution of the eco-friendly textile. The factors of CEOs' environmental sensitivity(internal factor), legal regulation(external factor), and firms' environmental management(internal factor), in descending order, significantly affected the price of the eco-friendly textile.

This study aimed to clarify relationships between the westernization of military uniform systems and changes in the textile import industry during the Eulmi reforms of clothing regulation. For the goal, the study investigated the content and features of that had been enacted under the Eulmi reforms. It also examined the status of the textile import industry at the time, especially in relation to outer garments such as jackets or Eui, trousers or Go, and overcoats. Moreover, this study inspected how the above westernization changed the textile import industry. More specifically, the research analyzed the content of based on articles from the then state newsletter or 『Gwanbo』, and the then cabinet meeting or Euijeongbu's proceedings or 『Euiju』. Concerning the textile import industry, this study looked into relevant descriptions and trade statistics from 『KOPEИ(Hankukji)』, and analyzed changes in that industry in connection with the introduction of Western military uniform systems. As a result, this study found that increased imports of cotton fabrics during the Eulmi reforms of clothing regulation was correlated with surging demand for shirt or lining materials and increase in the use of Myeonyung following military uniform westernization. Similarly, an increase in silk fabric imports was an outcome of increased demand for lining materials. Also, the import growth of woolen fabrics was seemingly attributed to the use of Heuknasa and Heukyung as basic materials of military uniforms. Thus, military uniforms began to be made of fabrics, which hadn't been used before in the wake of westernization. This development brought changes in the textile import industry, which is supported by textile import statistics of the time. In conclusion, the westernization of military uniform systems under the Eulmi reforms of clothing regulation was a significant factor that changed the industry.
