배준현,이종협 동양대학교 산업기술연구소 2000 東洋大學校 産業技術硏究所 論文集 Vol.2 No.1
Concerning environmental design, mass produced apartment does not express identity, that plays an significant role in community, and the exterior design of an apartment housing is important since the housing design affectsthe residents'life. In recent, there is an effort to creak diversification in apartment housing design following competition winning projects. To produce diverse apartment housing appearance, "combination among different dwelling unit vertical combination" by protrusion and subsidence of units should be studied and there should be more researches regarding economics and construction of apartment housing.
1P-148 Study on the Antibacterial property of ZnO glass
배준현,차재민,류봉기 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
Recently, many researches about a substitute material for inorganic antibacterial agents such as ZnO instead of organic antimicrobial agents have been conducted. In this study, we investigated ZnO effect not only as glass composition but also mill addition. The thermal, antibacterial and antifungal properties of ZnO-SiO<sub>2</sub>-B<sub>2</sub>O<sub>3</sub>-Na<sub>2</sub>O glasses were studied and the antimicrobial activity of ZnO in the form of mill addition was also measured. In order to analyze the thermal properties, the CTE and glass transition temperature were measured by TMA. For investigating antimicrobial properties, antibacterial activity against Escherichia coli (E. coli) was measured using JIS Z 2801 method and for antifungal properties, ASTM G 21 method was used to measure the resistance to five fungi. In this study, we have confirmed that the glass containing ZnO can be used in various fields by measuring the antimicrobial activity of the glass.

안양천등 관내하천에 대한 수질오염분석과 중금속 오염도 조사 및 생태학적분석에 대하여 연구하였다. 아울러 안양천 및 그 지류의 환경진단과 함께 하천을 살릴 수 있는 몇가지 제안을 하였다. 안양천 및 지류의 수질오염분석결과는 측정기간에 BOD값이 평균 25.5mg/L으로, 최저 17.0mg/L에서 최고 36.4mg/L으로 환경기준치를 초과하고 있다. 하천퇴적물에 대한 중금속 오염도 분석결과 5개항목 모두 기준치를 초과하여 높게 나타났으며, 특히 아연(Zn)의 농도는 매우 심각한 것으로 분석되었다. 분석결과는 Zn>Cu> Pb> As> Cd 순을 나타났다. 생태학적 분석에 있어서는 안양천의 상류에서 하류에 이르기까지 어류는 서식하지 못하고 있으며 하류 일부지역에서 오염이 강한 극소수 어류가 발견되었다. The water pollution problem with which Anyangchun river is confronted has been investigated. Water pollution analysis about Anyangchun river and rivers within the province, investigation of a contamination level of heavy metal and ecological analysis were studies. Also, we suggested a few ways to make rivers survive with Anyang watercourse and its tributaries diagnosed environmentally. The result of water pollution analysis for Anyangchun river and its tributaries during the period of measured BOD was average 25.5mg/L, ranging from minimum 17.0mg/L to maximum 36.4mg/L, which exceeds an environment standard level. According to the analysis result of heavy metal contamination level about the river deposit, all of 5 items exceeded the environment base point. Especially, concentration of Zinc was considered very serious. The result of analysis was proven in the order of Zn, Cu, Pb, As, Cd. In ecological analysis, fish couldn't living from the upper water to the lower one in Anyang river and a small minority of fish were discovered in part of the lower water.
PRAM 기록막용 Sb<sub>2</sub>Te<sub>3</sub> 박막의 질소 첨가에 대한 영향
배준현,차준호,김경호,김병근,이홍림,Bae, Jun-Hyun,Cha, Jun-Ho,Kim, Kyoung-Ho,Kim, Byung-Geun,Lee, Hong-Lim,Byeon, Dae-Seop 한국세라믹학회 2008 한국세라믹학회지 Vol.45 No.5
In this research, properties of $N_2$-doped $Sb_2Te_3$ thin film were evaluated using 4-point probe, XRD and AFM. $Sb_2Te_3$ material has faster crystallization rate than $Ge_2Sb_2Te_5$, but sheet resistance difference between amorphous and crystallization state is very low. This low sheet resistance difference decreases sensing margin in reading operation at PRAM device operation. Therefore, in order to overcome this weak point, $N_2$ gas was doped on $Sb_2Te_3$ thin film. Sheet resistance difference between amorphous and crystallized state of $N_2$-doped $Sb_2Te_3$ thin film showed about $10^4$ times higher than Un-doped $Sb_2Te_3$ thin film because of the grain boundary scattering.

Theres are some purposes on Neo-classicism with new criteria in France. France is the nation which has the start point Neo-classicism in Europe. Neo-classicism has the value with turning point to new stylistic period in pre modern-architecture and with motif on the remind with Classicism include Greece and Rome. And Neo-classicism supplied the base of Postmodernism about formal composition and theoretical roots. So, this study has the purposes on contemporary value of Neo-classicism and understanding the methods of formal composition.
몇가지 란탄나이드 이온과 12-crown-4 ether 및 15-Crown-5 Ether 간에 형성된 착물의 안정성에 대한 연구
배준현 안양대학교 자연과학연구소 1997 自然科學硏究 Vol.4 No.-
란탄나이드 이온인 Eu와 Tb을 선택하고 12-Crown-4 Ether와 15-Crown-5 Ether를 리간드로 하여 형성된 착물의 안정성을 연구하였다. Eu^3+ 및 Tb^3+ 이온들을 ethylacetate 혹은 dichloromethane 층으로 추출하였으며 이들간에 형성된 착물의 반대이온으로 benzoate를 선택하였다. Benzoate 이온으로부터 란탄나이드 금속이온으로의 에너지 전달에 의하여 유도되는 형광스펙트럼을 측정하였다. 이 결과를 바탕으로 유기용매층에 추출된 란탄나이드 금속이온들을 형광분석방법으로 정량할 수 있었다. 측정된 추출율을 이온-쌍극자 상호 작용으로 논하였다. 본 연구를 통하여 각종 란탄족 금속이온 및 무기 중금속이온들의 추출분리 및 정량에 이용할 수 있음이 기대 된다. It is results on the stability of complexes of some lanthanide ions with crown ethers types. The extraction of aqueous Eu^3+ and Tb^3+ ions into ethylacetate or dichloromethane were conducted by using 12-crown-4 ether and 15-crown-5 ether as ligand. Benzoate ion was selected as counter anion for the complexes formed between the lanthanide ions and crown ethers. Fluorescence spectra of the lanthanide ions induced by the energy transfer from benzoate anion to the cations were also measured. The quantitative analysis of the lanthanide ions extracted into organic phase were made on the basis of the interpreted in terms of ion-dipole interaction. The intensity of the 616nm fluorescence band Eu^3+ and the 546nm fluorescence band of Tb^3+ was monitored for the quantitative analysis.
