용매 변화에 따른 피롤 벤젠아민 유도체의 진동성분 일차 초편극률 변화
오주연,이영식 慶熙大學校 材料科學技術硏究所 1999 材料科學技術硏究論集 Vol.12 No.-
Experimental data are presented and discussed on the vibrational contributions β^(v) to molecular nonlinear optical(NLO) properties of benzene-pyrrole(BP) derivative in various solvents. Using a semi-classical model, the nuclear relaxation contributions is expressed in terms of vibrational spectroscopic observables namely frequencies and spectrum intensities. In this study, β^(v´)s of a BP derivative molecule in various solvents are determined using vibrational spectroscopy. To compensate the solvent contribution, the absolute Raman intensities of DMSO is also determined.

Objectives : Previous studies on N0TCH4 gene and schizophrenia have not produced consistent results, and more studies with various ethnicities and populations were warranted. This study was performed with Korean population to find the role of the N0TCH4 gene in the development of schizophrenia. Methods : 235 schizophrenics and 236 normal controls participated in the study. Two SNPs (-1725 A/G and -25 T/C) on the N0TCH4 gene were investigated. Genotyping was done by Taqman assay, and statistical analysis was done by contingency chi-square test for the allele and genotype frequencies and PowerMarker V3.0 for the haplotype. Results : The two SNPs did not deviate from Hardy-Weinberg equilibrium in neither schizophrenics or normal controls. Two groups were not different in terms of allele and genotype distribution for both SNPs. Two SNPs were found to be in linkage disequilibrium. Haplotype analysis could not find an association between schizophrenia and these two SNPs. There was no association between the age at onset and the genotypes for both SNPs. Conclusion : We could not find any significant association between schizophrenia and the N0TCH4 gene in this Korean population. Although there are limitations in this study, this result supports the conclusion that the N0TCH4 gene is less likely to play a major role on the development of schizophrenia in the Asian population.

In order to make use of the protection effect against wind by the vegetation, it examined whether it should make what vegetation form and arrangement using the 2-dimensional non-hydrostatic model. When the foliage shielding factor increases, it becomes hard to take in protection effect against wind in a residential section. When it makes height of vegetation high, it becomes hard to take in protection effect against wind with height. In the comparison in the case where vegetation high is gradually made low toward wind-stream from a vegetation, and the case of making it low gradually, although former tends to receive the protection effect against wind by the vegetation, attenuation of wind velicity becomes large. In the comparison in the case where foliage shielding factor and distribution of density of leaf are gathered gradually toward wind-stream from a vegetation. It has been understood to evaluate to height the influence that the vegetation multi-layer model by which the heat revenue and expenditure in the direction of the vegetation height is considered is used, and to characterize the vegetation group by the parameter setting.
Hantaan virus에 감염된 등줄쥐 폐조직중의 Reovirus 검출
오용주 고려대학교 의과대학 1983 고려대 의대 잡지 Vol.20 No.3
The followings are the results of the detection of Reovirus in the infected lung tissues of Apodemus agrarius with Hantaan virus, the etiologic agent of Hemorrhagic fever with renal syndrome. 1. About one third of infected Apodemus agrarius jejuensis with Hantaan virus revealed Reovirus antigen in the lung tissues and Reovirus antigen showed the quite different immunofluorescent reaction pattern compare with Hantaan virus antigen. 2. It was almost impossible to detect least amount of reovirus antigen in the infected lung tissues of Apodemus agrarius with Hantaan virus by indirect IF antibody technique. 3. Reovirus growed rapidly than Hantaan virus and produced CPE when the Hantaan virus seed of Apodemus mice lungs containing undetectable amount of reovirus by indirect IF technique was passaged several times in A549 cell cultures. 4. The detection of reovirus antigen in the lungs of mice inoculated blood specimens from Hemorrhagic fever with renal syndrome patients was dependent upon individual mouse and the source of reovirus contamination in the Hantaan virus seed was not blood of patients. These findings show that isolation of Hantaan virus from clinical materials and from infected Apodemus mice should be carefully done both in tissue culture cells and in normal Apodemus mice because about one third of Apodemus agrarius captured in nature were infected with Reovirus.

In this paper, we are considered various possible disturbance conditions in order to design controller, H∞ optimal controller is successfully designed to control in such as situations. To do this, we are determined weighting function and design parameter γ to method of trial and error by Glover-Doyle algorithm. To compare with H∞-PSS and conventional-PSS which is applied in nominal system and load variations, the dynamic characteristics of H∞-PSS controller was verified which has a good response.
β-glycerophosphate 혼합시 인간 치수 세포에 대한 Portland cement의 생활성에 관한 연구
오영환,장영주,조용범 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.5
β-glycerophosphate는 치수의 상아모세포 분화를 촉진하는 물질이다. Portland cement는 수중에서 장기간에 걸쳐 용해되기 때문에 β-glycerophosphate을 혼합한 Portland cement는 수산화칼슘과 함께 β-glycerophosphate를 장기간 용출하게 된다. 본 실험에서는 β-glycerophosphate을 혼합한 Portland cament에 대한 인간치수세포의 반응을 알아보았다. 인간 치수 세포에 대한 β-glycerophosphate의 효과를 알아보기 위해 다양한 농도의 β-glycerophosphate와 dexamethasone에 대한 인간 치수 세포의 ALP activity을 측정하였고 alizarin red S로 염색하여 관찰하였다. β-glycerophosphate가 다양한 농도(10 mM, 100 mM, 1 M)로 혼합된 Portland cement에 대한 인간 치수 세포의 MTS assay, ALP activity를 측정하고 SEM으로 관찰하였다. 치수세포의 석회화 정도를 관찰한 연구에서 β-glycerophosphate와 dexamethasone 단독으로 적용하였을 때 거의 효과가 없었으나 5 mM β-glycerophosphate와 100 nM dexamethasone을 혼합 적용하였을 때 가장 높은 ALP acticity를 보였다. 분화제를 첨가하거나 첨가하지 않은 모든 실험군에서 치수세포에 대한 독성은 관찰되지 않았으며 Portland cement에 10 mM β-glycerophosphate을 혼합한 시편의 ALP activity가 대조군에 비교하여 가장 많이 증가하였다. 결론적으로 β-glycerophosphate이 혼합된 Portland cement는 세포 독성이 없으며 첨가물이 없는 Portland cement에 비해 치수 분화 및 석회화를 더 많이 일으키므로 임상적으로 β-glycerophosphate을 혼합한 Portland cement 적용은 재료 하방에 더 많은 상아질을 형성시킬 것으로 추측된다. The purpose of this study is to investigate the response of human pulp cell on Portland cement mixed with β-glycerophosphate. To investigate the effect of β-glycerophosphate and/or dexamethasone on human pulp cell, ALP activity on various concentration of β-glycerophosphate and dexamethasone was measured and mineral nodule of human pulp cell was stained with Alizarin red S. MTS assay and ALP activity of human pulp cell on Portland cement mixed with various concentration of β-glycerophosphate (10 mM, 100mM, 1M) was measured and the specimens were examined under SEM. Addition of β-glycerophosphate or dexamethasone alone had no effect however, the addition of 5 mM β-glycerophosphate and 100 nM dexamethasone had the largest increasement in ALP activity. There was no toxicity in all samples and the data showed that Portland cement mixed with 10 mM β-glycerophosphate had more increase in ALP activity compared with control. In conclusion, Portland cement mixed with β-glycerophosphate has no toxicity and promotes differentiation and mineralization of pulp cell compared with additive-free Portland cement. This implicated that application of Portland cement mixed with β-glycerophosphate might form more reparative dentin and in turn it would bring direct pulp capping to success.

Four Years Reports of "Journal of Korean Neuropsychiatric Association" during 2001 to 2005 were evaluated by 18 Editorial Board of Korean Neuropsychiatric Association. We investigated the articles to specific fields and rejection rate etc. by different section chiefs. Although several problems concerning review time duration and rejection guideline issues indicated but generally all reviewer processes proved relatively clear and concise criteria. Through these objective and systematic evaluation Processes, "Journal of Korean Neuropsychiatric Association" will develop a good journal.
