패션디자인기업의 머천다이징 정보활용에 따른 정보데이터베이스 분류에 관한 연구
이홍림 한국디자인과학학회 2000 디자인과학연구 Vol.6 No.-
정보통신의 발달로 정보관련산업과 정보서비스산업이 기업경영의 새로운 패러다임으로 부각되고 고도 디지털 정보사회에서 정보에 대한 새로운 인식과 정보활용 및 정보화 네트워크 구성이 요구되어지고 있다. 패션기업의 정보화와 관련된 정보D/B(Data Base: 데이터베이스) 유형 분류체계의 궁극적 목적은 기업의 수익원인 상품정보에 있다. 디자이너와 머천다이저 등의 의사결정을 지원함으로써 패션상품의 경쟁력을 강화시키고 패션기업의 경쟁 우위적 마켓력 향상에 지대한 영향을 미친다고 볼 수 있다. 또한, 정보의 관리 및 처리에 관한 기술적 연구나 정보화 시스템의 시대적 인식결여 및 비효율적 운영상의 문제점도 들 수 있다. 이로 인하여 객관적 패션정보자료의 부족과 비체계적 정보수집 및 분석의 문제점이 지속적으로 반복되고 있다. 이같은 현실상황에서 국제화, 세계화되는 패션시장에서 경쟁우위적 디자인력을 갖추기 위해서는 정보화의 기초적 연구인 정보화의 개념과 정보에 대한 명확한 인식과 더불어 표준화된 정보 D/B 유형별 분류 시스템을 정립함으로써 이루어질 수 있다고 본다. New understanding and use of information, and construction of informationization network are needed in the advanced digital Information society where information-related-industry and information service industry become new paradigm of business management as information technology industry developes. The ultimate object of classifying system related to the informationization of fashion industry is he "Merchandise" that makes profits for a company. The classifying system strengthens the ability of fashion merchandising by supporting designer and merchandiser's choice making, and raise the competitive power of a fashion company in marketing.(There are several problems in the current fashion industry). They are the lack of technical studies about management and treatment of technical studies about management and the noneffective operation Therefore the lack of objective database on fashion, nonsystematic information collecting and analyzation occr repeatedly. As the fashion market gets internationalized and globalized, to have the competitive power in design, we need to understand clearly the concept of Information, which is a basic study of informationization, and establish the standardized classfying system by information D/B type.

Al(OH)<sub>3</sub>-SiO<sub>2</sub>-AlF<sub>3</sub>계에서 기상-고상반응에 의한 뮬라이트 휘스커 합성
이홍림,강종봉,Lee, Hong-Lim,Kang, Jong-Bong 한국세라믹학회 2006 한국세라믹학회지 Vol.43 No.6
In the $Al(OH)_3-SiO_2-AlF_3$ system, leaf-shaped fluorotopaz was first formed at $800^{\circ}C$ and mullite whisker was formed at $1,100^{\circ}C$. The mass transportation of Al and Si as gas phase, the fast reaction and growth, and the absence of liquid phase existence in mullite whisker showed that the formation and growth of mullite was from the solid-vapor reaction.

Aluminum hydroxides were prepared by the alkoxide hydrolysis method using Al-isopropoxide as a starting material and NH4OH as a catalytic agent. When Al-isopropoxide was hydrolyzed in a H2O-NH3 system, only Al(OH)3 was obtained over all pH values. However, AlOOH was formed besides Al(OH)3 when Al-isopropoxide was hydrolyzed in a H2O-NH3-isopropyl alcohol system. The AlOOH/Al(OH)3 ratio was increased as the isopropyl alcohol content was increased. The hydroxides, Al(OH)3 and AlOOH, obtained in this study and the commerical products, $\alpha$-Al2O3 and AlOOH were subjected to the carbothermal reduction and nitridation reaction to product AlN powder, using carbon black as a reducing agent under N2 atmosphere at various temperatures. AlN was synthesized from the obtained Al(OH)3 and the commercial AlOOH at 145$0^{\circ}C$, however, synthesized from the obtained AlOOH and the commercial alpha-alumina at 135$0^{\circ}C$. The temperature difference is assumed to be attributed to the reactivity of those powders. AlN powder prepared from the Al-isopropoxide was observed to have the narrower particle size distribution than that prepared from the commercial $\alpha$-Al2O3 or AlOOH.

알콕사이드로부터 Si-Al-O-N계 분말합성 II. 알콕사이드로부터 합성한 Si3N4 및 $\beta$-Sialon의 분말 및 소결체의 특성
이홍림,전명철 한국세라믹학회 1989 한국세라믹학회지 Vol.26 No.2
Fine Si-Al-OH coprecipitate powders were prepared from Si- and Al-alkoxides by the hydrolysis method. $\beta$-Sialon powder was obtained from prepared Si-Al-OH coprecipitate by the simultaneous reduction and nitridation method. The syntehsized Sialon powder was pressureless sintered at 175$0^{\circ}C$ for 90 min in N2 atmosphere. The characterization of the Sialon powder was performed with XRD, BET, SEM, TEM and particle size analysis. The sinterability and mechanical properties of sintered bodies were investigated in terms of relative density, M.O.R., fracture toughness, hardness and the morphology of microstructure. The highest values of their mechanical properties were obtained for the $\beta$-Sialon ceramics at Z=1 and those values are as follows : M.O.R., KIC and HV of $\beta$-Sialon ceramics(Z=1) are 499.1 MPa, 5.9MN/m3/2 and 18.7GPa, respectively.

Silicon nitride powder synthesized from Kimcheon quartzite and commercial reagents, AlN and Y2O3 powders were used to prepare the partially and fully stabilized Y-${\alpha}$-Sialon ceramics by the pressureless sintering at 1800$^{\circ}C$ for 2 hours in N2 atmosphere. Good mechanical properties of the prepared Y-${\alpha}$-Sialon ceramics were found over 0.4∼0.6 of the Yttrium solubility range, X, in the equation Yx(Si12-4.5x, Al4.5x)(O1.5x, N16-1.5x). The properties of these prepared Y-${\alpha}$-Sialon ceramics were compared with those prepared in the same way from a commercial Toshiba Si3N4 powder.

공침법으로 제조한 $Al_2O_3-ZrO_2$ 계의 세라믹스의 기계적 성질
이홍림,홍기곤,정형진 한국세라믹학회 1986 한국세라믹학회지 Vol.23 No.3
$Al_2O_3-ZrO_2$ ceramics was obtained by the co-precipitation method using $Al_2(SO_4)_2$.$18H_2O$ and $ZrOCl_2$.$8H_2O$ as starting materials $MgCl_2$.$6H_2O$ as a sintering aid and NH4OH as a hydrolyzing agent. The coprecipitate from the above raw materials was calcined at 125$0^{\circ}C$ for 1h and again sintered at 1$650^{\circ}C$ for 2h before measurements of strength hardness and fracture toughness. MgO addition was found to increase mechanical properties of the $Al_2O_3-ZrO_2$ system. The strength and frac-ture toughness of $Al_2O_3-ZrO_2$ ceramics were considered to be increased by stress-induced phase tranforma-tion of $ZrO_2$.

이홍림,장병국 한국세라믹학회 1986 한국세라믹학회지 Vol.23 No.4
$\beta$-Sialon powders were prepared by the reduction-nitridation reaction from the mixture of Wando-pyrophyllite and graphite at 135$0^{\circ}C$ in $N_2-H_2$ atmosphere. The $\beta$-Sialon powders were sintered at 175$0^{\circ}C$ by the pressureless sintering for 90min and the hot-pressing for 60 min respectively. All the sintered bodies showed their relative densities higher than 94% The values of M.O.R fracture toughness(KIC) and hardness showed 32.9kpsi 2.9MN/$m^{1.5}$ , 12.1GN/$m^2$ for the pressure-less sitnered bodies and 48.6kpsi, 4.6 MN/4m^{1.5}$ 15.3GN/$m^2$ for the hot-pressed bodies respectively.
