고속액체 크로마토그라프법을 이용한 제제중 Aclatonium Napadisilate 의 정량 및 함량균일성에 관한 연구
김용주,허재두,김면종,박세호,노회숙 한국약제학회 1986 Journal of Pharmaceutical Investigation Vol.16 No.2
A convenient high performance liquid chromatographic method was established for the quantitative determination and content uniformity test of aclatonium napadisilate preparation. This method was more simple to make the sample solution for injection, and easy to determine the content in the preparation. Aclatonium napadisilate was chromatographed using a Lichrosorb-NH₂ column (4㎜ × 25 ㎝, and acetonitrile-water mixture (83:17) as an eluent at a flow rate of 1.8 ㎖/min. RI-detector response was linear over a range of 0.5∼2.0% aclatonium napadisilate under above conditions. Reproducibility studies gave relative standard deviation of 1.29%.

Analysis of ^(16)O+^(208)Pb Elastic Scattering with Eikonal Approximation
김용주,박규은 濟州大學校 師範大學 科學敎育硏究所 1992 科學敎育 Vol.9 No.1
Using the phase shift analysis based on the eikonal approximation. the analysis for elastic scattering data of ^(16)O + ^(208)Pb system at E_(lab)=793 and 1503 MeV are performed. The experimental data and the calculated results are found to agree each other comparatively.

韓國의 敎師敎育 改善을 위한 一 硏究 : 아세안 國家와의 比較를 中心으로 Compared with ASEAN Countries
金容周 울산대학교 1983 연구논문집 Vol.14 No.2
本 硏究는 敎師敎育이 敎師의 專門的 役割의 伸張과 資質向上에 초점이 두어져야 한다는 前提하에 이루어졌다. 本 硏究의 目的은 우리나라 敎師敎育의 改善을 위한 準據를 제시하는데 있다. 이를 위하여 本 硏究에서는 1) 變化하는 社會가 요구하는 敎師의 役割과 敎師敎育 2) 韓國敎師敎育制度의 過去와 現在 3) 아세안 國家의 敎師敎育 動向등이 비교 검토되었다. 本 硏究의 結論은 우리나라 敎師敎育의 改善方案을 制度的인 側面과 敎育內容의 側面에서 제시하는 것으로 대신하였다. The basic assumption of this study is teacher education should be focused on broadening teacher's professional role and on improvement of teacher's quality. The major objective of this study is to provide some references for development of teacher education in Korea. For the purpose of this study, the followings are discussed: 1)teacher's role and teacher education that the changing society needs 2) the past and present of teacher education system in Korea 3) the trends on teacher education ASEAN countries. The results of the study are replaced with suggestion on the new ways for development of Korean teacher education through the aspects of the systems and the contents.

製造條件에 따른 甘草 및 甘草含有 製劑中의 Glycyrrhizin 量 의 變化
김용주,김재백 圓光大學校 藥品硏究所 1986 藥品硏究所報 Vol.1 No.1
After extracted by following three methods. glycryrrhizin content in Glycyrrhizae Radix and its preparation was determined by HPLC. (1) KP IV method : Infusion, decoction, extract, crude extract and percolation. (2) Parched method : After Parched, extracted by general method. (3) General method : Glycyrrhize Radix and its preparation extract as follows : extracted temperature (60℃, 100℃), extracted time (12, 24 hours), volume of extracted solvent (300ml/Glycyrrhizae Radix 1g, 600ml/Glycyrrhizae Radix 1g) In the case of KP IV method, percolation method appeared the highest value. In the case of parched method, appeared the low value. In the case of general method, appeared the following result. Glycyrrhizae Redix haven't an effect on the extracted temperature and the extracted time, but in the case of the volume of extracted solvent (600ml/Glycyrrhizae Redix 1g) appeared the highest value. Glycyrrhizae Redix preparation haven't an effect in the extracted temperature, the extracted time and the volume of extracted solvent, appeared lower than Glycyrrhizae Redix. In the case of comparison all-inclusively, percolation method in KP IV method appeared 3, 87% value, but general method appeared the highest 5, 30% value.

Phase Shift Analysis of α + 116Sn and α + 197Au Elastic Scatterings at Elab = 240 MeV
김용주 한국물리학회 2021 새물리 Vol.71 No.11
The Coulomb-modified Glauber model is employed to analyze the experimental data for alpha particle elastic scatterings on 116Sn and 197Au at Elab = 240 MeV. We used the surface-matched Gaussian density (SMGD) obtained by matching the Gaussian density profile function to the two-parameter Fermi one for the target nuclei. Calculations with the SMGD are found to reproduce reasonably the structure of the differential cross sections and to give better fits to the elastic data than the calculations without SMGD. The oscillatory behaviors of the elastic angular distributions are found to be related to the strong interference between the near-side and the far-side scattering amplitudes. The inverse potentials calculated with the SMGD provided more closer to the optical model ones in the vicinity of strong absorption radius compared to the potentials calculated without SMGD. We can see that the adoption of the SMGD is useful for obtaining an improved fit to the heavy-nucleus elastic scattering data.
