Taekwondo and Creative Economy: Fusion Taekwondo Performance ‘KICKs’
( Jinyinzhe ) 한국체육학회 2016 국제스포츠과학 학술대회 Vol.2016 No.1
Purpose: The slogan ``creative economy`` has been rising suddenly in all fields of interest recently. Creative economy is combining imagination and creativity with ICT(Information & Communication Technology) to create new industry and fortify existing industry. Creative economy is similar to ``fusion`` in having ``creativity`` as its core value and characteristic, fusion in creative economy is not only insisting on new techniques and services, but using existing ones creatively, and combining them with necessity of different fields to create new field of interest. Method: Creative economy ultimately works for human-centered innovation, and even the purpose must focus on maximizing human happiness. This is the key point of creative economy. Hence, this study attempted to find new vision and alternative of Taekwondo performance and the possibility of fusion performance in theoretical framework of ``humanism``. There is no doubt that there are various complex elements in fusion performance and creative economy of Taekwondo, but only when we base these on humanism, we could elevate the value of human life to satisfying, healthy, and abundant state. Result: KICKs is a fusion performance about Taekwondo, that elevated Taekwondo performance as an art genre. It also pursuits modern Taekwondo that could appeal to the world. Its visual elements and concepts derived from RPG (role-playing game) overcame the limits of non-verbal performance, and gave satisfaction to the audience by materializing virtual reality with images, holograms, and mapping. Moreover, it shows liveliness with real sparring, and the height tehcniques with extreme breaking and Taekwondo kicks. Conclusion: We often misapprehend ``fusion`` as combination by considering it as mere addition or physical combination. However, fusion is above and beyond mere unity; it creates new values through organic bond. That is, fusion is about making a meaningful solution rather than a formal form. For example, KICKs is a performance about ``human body``. Each Taekwondo movement is passed on to the audience as body language, and powerful punches and kicks are like lines of actors. stereoscopic images givea new rise Taekwondo performance, and creative economical value of Taekwondo is expected with fusion performance.

Jin, Yinzhe,Row, Kyung-Ho Korean Chemical Society 2007 Bulletin of the Korean Chemical Society Vol.28 No.2
In this work, caffeine and some catechin compounds + C, EC, EGC, and EGCG were extracted from green tea by using molecular imprinted polymers (MIP) as sorbent materials in a solid-phase extraction (SPE) process known as MISPE (molecular imprinted solid-phase extraction). For synthesis of MIP, caffeine was employed as the template, MAA as the monomer, EGDMA as the crosslinker, and AIBN as the initiator. A solution of caffeine (0.2 mg/mL in methanol) was utilized in the solid extraction cartridges following loading, washing, and elution procedures with acetonitrile, methanol, and methanol-acetic acid (90/10, %v/v) as the solvents, respectively. This solid-phase extraction protocol was applied for the extraction of caffeine and some catechin compounds from green tea. A comparison was made between the results obtained with the MIP cartridges and a traditional C18 reversed-phase cartridge. It was thereupon found that the recovery of caffeine by the MIPbased sorbent used in this work was almost two and four times greater than that by a commercially available C18 material. A quantitative analysis was conducted by high performance liquid chromatography (HPLC) using a C18 column (5 μm, 250 × 4.6 mm) with methanol/water (40/60, %v/v) as the mobile phase at a flow rate of 0.5 mL/min.

Adsorption Isotherms of Catechin Compounds on (+)Catechin-MIP
Jin, Yinzhe,Wan, Xiaolong,Row, Kyung-Ho Korean Chemical Society 2008 Bulletin of the Korean Chemical Society Vol.29 No.8
A molecular imprinted polymer (MIP) using (+)catechin ((+)C) as a template and acrylamide (AM) as a functional monomer was prepared. Acetonitrile was used as the porogen with ethylene glycol dimethacrylate (EGDMA) as the crosslinker and 2,2'-azobis(isobutyronitrile) (AIBN) as the initiator. The adsorption isotherms in the MIP were measured and the parameters of the equilibrium isotherms were estimated by linear and nonlinear regression analyses. The linear equation for original concentration and adsorpted concentrations was then expressed, and the adsorption equilibrium data were correlated into Langmuir, Freundlich, quadratic, and Langmuir Extension isotherm models. The mixture compounds of (+)C and epicatechin (EC) show competitive adsorption on specific binding sites of the (+)catechin-MIP. The adsorption concentrations of (+)C, epicatechin (EC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG), on the (+)catechin-molecular imprinted polymer were compared. Through the analysis, the (+)catechin-molecular imprinted polymer showed higher adsorption ability than blank polymer which was synthesized molecular imprinted polymer without (+)catechin. Furthermore, the competitive Langmuir isotherms were applied to the mixture compounds of (+)C and EC.

Separation of Catechin Compounds by Retention Theory in RP-HPLC
Jin, Yinzhe,Row, Kyung Ho Marcel Dekker 2007 JOURNAL OF LIQUID CHROMATOGRAPHY AND RELATED TECHN Vol.30 No.3
<P> An efficient optimization method was used to separate catechin compounds by RP-HPLC. In this work, the binary mobile phase of water and acetonitrile was used with the buffer of acetic acid (AA). The elution profiles were calculated by the plate theory based on the linear and quadratic equations of retention factor, lnk=Inkw+SF, lnk=L+MF+NF2, k=A+B/F, where F was the vol.% of acetonitrile. We modified the retention theory to calculate the elution profile in both isocratic and gradient modes. The final calculated results showed that the first mobile phase composition was water in 0.1% AA/acetonitrile in 0.1% AA, 90/10 vol.%, followed 30 min later by the second composition of mobile phase, which was linearly changed to 70/30 vol.%. In the experimental conditions, the agreement between the experimental data and the calculated values was relatively good. Catechin compounds from Korean and Chinese green tea as potential powers of anticancer and antioxidant components were target materials in this work. The full content of the catechin compounds of EGC, (+) C, EC, EGCG, and ECG in Chinese green tea extracted was 249.92 mg/g, so it was 2.15 times of that from Korean tea.</P>
