ESR 및 ESEM을 이용한 MnAPSO-34 Mn(Ⅱ)의 골격치환에 대한 분광학적 증거
백건호 昌原大學校 基礎科學硏究所 1998 基礎科學硏究所論文集 Vol.10 No.-
Electron Spin Echo modulation analysis of 0.1 mole of MnAPSO-34 with adsorbed D₂O shows two deuteriums at 0.29 nm and two at 0.30 nm from Mn. At low manganese content (0.05 mole %) in MnH-SAPO-34 with adsorbed D₂O shows four deuteriums at 0.31 nm and two at 0.31 nm from Mn. This suggests that two waters hydrate an MnO₄ configuration with a D-O bond orientation for the waters as expected for a negatively charged site. The framework incorporation in MnAPSO-34 is confirmed by a three-pulse ESEM study of deuterium modulation resulting from interactions of deuterated adsorbates with manganese which indicates that the manganese occupies a negative charged site in MnAPSO-34.
ESR 및 ESEM을 이용한 VH-SAPO-11의 V(IV)화학종, 위치 및 흡착상호작용에 관한 연구
백건호,백승찬 昌原大學校 基礎科學硏究所 2002 基礎科學硏究所論文集 Vol.14 No.-
Vanadium-doped H-SAPO-11 samples were prepared by a high-temoerature solid-state reaction between SAPO-11 and the paramagentic V(IV) species and characterized carefully by ESR and Electron Spin-Echo Modulation(ESEM) studied. However,subsequent oxidation result weak paramagnetic V(IV) species,subsequent activation results in the formation of V(IV)species exist as vanadyl ion either as (V(IV)O)^2+ or V^4+. The (V(IV)O^2+ species seem more probable because of the following reasons.Since SAPO-11 have a low negative framework charge^32,more positively charged species, like V^4+ are not as easily stabilized.Tetravalent vanadium ion can only be observed at or below 77 K, the activated sample of VH-SAPO-11 can be measured even at room temperature. After adsorption of methanol, ethano, propanol, only one molecule coordinates to (V(IV)O)^2+ was observed in ESR and ESEM spectra.
폴리에스터 섬유에 응용되는 Photochromic 분산염료에 있는 치환기효과에 따른 염착량의 변화

1:1 Complex of (Ⅰ;R=4-amino-2,6-dichlorophenyl,Ⅱ;R=4-amino-3,5-dichlorophenyl) organomercury cation ?? and dithizone have been synthesized. Indication of hydrogen bond of these compounds with polyester was obtained from solvent extraction studies. The return time ofⅠdispersion dye dissolved in toluene from orange through blue to original colour was 22.5 minutes and was 12 minutes in case of sample Ⅱ. Thermal stability of Ⅰ was higher than that of Ⅱ by +Ⅰ effect of electron releasing group but photochemical stability of Ⅰ solution dissolved in toluene was similar to that of Ⅱ dispersion dye solution. Optimal pH of Ⅰ & Ⅱ was 6, and 7, respectively. Amount taken up by Ⅰ was 14 times higher than by Ⅱ.

Thermal and cw CO₂laser-induced decomposition reaction of gaseous UO₂(hfacac)₂THF was investigated in a static and dynamic molecular beam cell. In a static cell, thermal decomposition reaction proceeded in two different ways with heating temperature variance and it was monitored by observing the IR absorption band. In a molecular beam cell, the sample was irradiated by using gratingtuned cw and TEA CO₂laser and photolysis products were separated by thermal-gradient fractional sublimation method and solvent extraction method.
4-(p-dimethylaminobenzeneazo)phenylmercuric dithizonate의 합성 및 염료로서의 적합성 연구

1:1 Complex of organomercury cation HgR^(+) (Ⅰ; R= 4-(p-dimethylamino benzeneazo)phenyl, Ⅱ; R=p-N, N-dimethylaminophenyl) and dithizone have been prepared, characterized, and examined for their photochemical and phototropic behavior in solution and thermal stability for their solid state with IR, Visible, NMR spectrophotometer, DSC, TGA. The photochemical stability of 4-(p-dimethylaminobenzeneazo)phenylmercuric dithizonate in n-propyl alcohol and thermal stability for the solid state were better than those of p-N, N-dimethylaminophenylmercuric dithizonate.

1:1 Complex of (Ⅰ;R=p-N, N-dimethylaminopheny1 Ⅱ;R=p-aminopheny1) organomercury cation ?? and dithizone have been prepared, characterized, and examined for their photochemical and photochromic behavior in solution and thermal stability for their solid state with IR, Visible, NMR spectrophotometer, DSC, and TGA. The photochemical stability of the Ⅰ solution in toluene and thermal stability for the solid state of Ⅰ was higher than those of Ⅱ. However, dye uptake by Ⅱ was higher than that by Ⅰ. Optimum pH of Ⅰ & Ⅱ dyeing on polyester was 7 and 5, respectively.
중국 WTO 가입 이후 시장환경 변화에 따른 마케팅 전략
백건호 계명대학교 국제학연구소 2003 국제학논총 Vol.8 No.-
As Chinese economy having been globalizing rapidly since she had obtained a membership of WTO at the end of 2001, FDI to China has also been growing up to the volume of more than 5million dollars per year and FEIs in China has begun to shift their strategies from localization to globalization at view point of macro perspectives. But, we can find more localized responses in terms of micro levels such as marketing, leadership, HRM etc. This paper is going to suggest a hypothesis that the more globalized the business environment in China, the more localized elaborations to be needed for FIEs to respond to the Characteristic of the China market, which is beginning to intergrate into the global market. Actually, more than 300s MNEs of world big 500s have committed their core resources such as R&D center and marketing center as well as strategic center for global market. It means that the globalization of China market has made FIEs to take their commitment strategy to shift core competences into China, namely localization in terms of core resources deployment. It is quite natural that the more core resources shifted, the more localizing the administrative management of chinese subsidiaries needed. This paper insist that the localization of 4Ps is quite essential for the FIEs to succeed and survive in the China market, especially product/price localization in terms of differentiation with low cost, integration & networking of distribution channel with SCM & CRM, local brand naming are the core competence to compete in the China market. This paper suggest the firms who whish to succeed in the China market must be aware that the characteristic of China market is fast changing, segmented and differentiated according to regions and income levels etc.
