Objective: The authors investigated the frequency of persecutors in persecutory delusions of the psychiatric patients who didn't undergo the arrest or traumatic injury, reside in Gwangju Jeonnam area, and were admitted to the hospital after the 5.18 prodemocracy movement in Gwangju in 1980 upward 10 years. Also this study investigated the frequency of the persecutors before and after the prodemocracy movement and in capital and Gwangju Jeonnam area. Subjects and Methods: Among the 896 patients who were admitted to department of psychiatry, Chosun University Hospital from Jan. 1. 1989 to Dec. 31. 1991, we choosed 144 patients with persecutory delusion who had lived in Gwangju Jeonnam area for 10 years after 5.18 prodemocracy movement as subjects. Persecutors were classified into 7 class: unspecified, family, neighbors, communist or spy, police or army or secret agent, impersonal, others. Results: 1) In our study, the frequency of persecutors was family, unspecified, neighbors, police or army or secret agent, impersonal, others, communist or spy in descending order. As compared to previous studies (1956-2003) including our study about frequency of persecutor at capital area and Gwangju Jeonnam area, and before and after 5.18 prodemocracy movement, 2) At capital area, in the early 1980s, police, family, neighbors, unspecified person was frequent in descending order. In the both of early 1970s, 1990s, neighbors, family, unspecified person, police was frequent in descending order. 3) At Gwangju Jeonnam area, in the early 1970s, family, unspecified person, neighbors, police was frequent in descending order. In the early 1990s, unspecified person and family, neighbors, police was frequent in descending order. 4) The police class was most frequent at capital area in the early 1980s. Conclusions: We suppose that class of persecutor in persecutory delusions of psychiatric patients are changing according to social change, and frequency of police class was decreasing in both of capital and Gwangju, Jeonnam area.

TFELD 절연층을 위해 ITO glass위에 증착된 (Ba_(0.5),Sr_(0.5))TiO₃박막의 특성

김정환,배승춘,권성렬,정훈,박진우,김기완 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

We have studied that dielectric and electrical properties of (Ba_(0.5),Sr_(0.5))TiO_(3) thin films deposited on Indium Tin Oxide-coated glass substrate by using rf-magnetron sputtering method in this paper. Substrates were heated at room, 300℃ , 400℃, and 500℃. Working pressure was changed 5mTorr, 10mTorr, 20mTorr, 30mTorr respectively substrates temperature, and Ar:O_(2), ratio was fixed 9:1. SEM analysis was conducted to investigate thickness of BST thin films. Dielectric constant, current-voltage(I-V), and transmittance were measured. We observed difference of that thickness, dielectric constant, current-voltage(I-V), and transmittance due to variable substrates temperature and working pressure. We also obtained best conditions at 400℃, 30mTorr. Dielectric constant was 209.1 at 1kHz, leakage current density was below 7.35X10^(-7)A/cm^(2) at 100V, and transmittance was over 91%.

견운모의 표면개질에 따른 기초물성연구

김창욱,정인,윤성렬,한승희 광운대학교 신기술연구소 1997 신기술연구소논문집 Vol.26 No.-

견운모는 천연적으로 초미립의 판상형에 의한 윤활성이 뛰어난 광물 중 하나이지만, 광물 본질이 지니는 흡수력으로 인하여 정밀화학 공업분야에서 이용할 때 소수성이 떨어지므로 견운모 미립자의 표면개질이 불가피하다. 따라서 본 연구에서는 실리콘오일과 금속비누를 이용하여 견운모 미립자에 표면개질을 시행함으로써 기초 물성변화를 관찰하였다. 이러한 연구를 수행하기 위하여 평균 약10μm의 정제견운모 미립자에 세 가지 종류의 실리콘오일을 흡착시켜 표면처리한 후 실리콘오일에 흡착된 각 미립자 산물의 소수성 및 내유성 실험을 시행하였다. 또한 적외선 분광법을 이용한 기기를 사용하여 견운모 표면에 오일이 흡착되었는지 조사하였으며, 열감량분석기를 이용하여 실리콘 흡착량에 따른 감량변화를 조사하였다. 그리고 그 특성이 우수한 실리콘의 함량비를 기준으로 견운모미립자에 금속비누를 표면처리한 후 그 특성을 비교하였다. 견운모 미립자에 실리콘오일의 흡착 후 소수성 및 내유성이 가장 우수한 실리콘 오일과 견운모의 중량비는 KSDMPS 6wt%일 때였다. 적외선분광기기를 이용하여 견운모에 실리콘오일 흡착확인을 하여 본 결과 흡착이 되었음을 확인하였고, 실리콘오일 함량이 늘어감에 따라 그 피크가 커짐을 확인 할 수 있었다. 이 또한 열감량분석기로 확인하였으며, 실리콘오일의 함량에 따라 막 두께도 조정됨을 알 수 있었다. 소수성과 내유성이 가장 우수한 KSDMPS는 6wt%일 때 소수성은 70.50%였고 내유성은 43.75%였다. 그리고 금속비누로 표면개질하였을 때와 소수성을 비교하여보면 실리콘오일로 표면개질 하였을 때 소수성이 우수하였다. Sericite is known to be an excellent natural lubricant due to fine particle texture and tabular crystal structure. However, the surface must be specially treated because sericite also possesses the water absorbing property. In this study, we investigated effects of silicone oil and metal soap on Sericite’s fine particle texture and other properties. Surface treatment effects of three different kinds of silicon oil on purified sericite particle having the mean of l0μm were studied and the changes in water and oil repellence were investigated. Through IR spectrometer, silicon oil adsorption on sericite particle was investigated, and thermogravimetric analysis was used to study the reduced adsorption of silicon oil on sericite particle surface. By taking the best parameters of silicon oil amount into consideration, the study on surface treatment using metal soap was carried out. Finally, the surface treatment effects of metal soap and silicon oil were compared. The optimum water and oil repellence was when the sericite fine particle adsorbed with silicon oil at the ratio of KSDMPS 6wt%. It was found that the surface treatment by silicon oil was superior to the treatment by metal soap in water repellence.

김은홍,김재진,정승렬,전성현 한국경영과학회 1999 한국경영과학회지 Vol.24 No.4

Recently, implementing ERP(Enterprise Resource Planning) systems has been one of major concerns of many companies. Despite the trend in the business area, few theoretical researches about the ERP have been published to date. The primary purpose of current study, therefore, lies in examining the effects of change management characteristics on ERP performance. Top management support, user participation, and consulting support were selected as change management characteristics. Additionally, ERP implementation characteristics were considered as contingency variables which may moderate the relationships between change management characteristics and ERP performance. Two ERP implementation characteristic variables introduced in this study were ERP implementation approach and ERP implementation strategy. Hypotheses concerning the relationships among those variables of change management characteristics, ERP performance and ERP implementation characteristics were empirically tested. The findings show that change management characteristics are strongly correlated with ERP performance, and ERP implementation characteristics have contingency effects, partially at least, on the relationship between change management characteristics and ERP performance.

폴리카프로락톤 매트릭스로부터 세파드록실의 방출에 미치는 BSA의 영향

김승렬,정연진,김영미,이치호,김대덕 한국약제학회 2004 Journal of Pharmaceutical Investigation Vol.34 No.5

In order to investigate the effect of bovine serum albumin (BSA), as a pore former, on the controlled release of an antibiotic from a biodegradable polymeric device, polycaprolactone (PCL)-cefadroxil matrices were prepared by the solvent casting method. The amount of cefadroxil released from various formulations at 37℃ was measured by HPLC. The duration of antimicrobial activity of matrices against S. aureus was evaluated by measuring the diameters of the inhibition zone. The morphology of the matrices was investigated by scanning electron microscopy (SEM). The release rate and extent of cefadroxil from PCL matrix increased as the loading dose and particle size of BSA/cefadroxil mixture powder increased. Cefadroxil released from the matrix exhibited antibacterial activity for up to 4 days. SEM of the cross-section of matrix showed the typical channel formation after 3 days of release study. Thus, a biodegradable polymeric matrix loaded with antibiotic/BSA mixture can effectively prevent bacterial infection on its surface, thereby bringing about an enhancement of biocompatibility of biomaterials.

임승민,안정조,최영,조현경,김민상,유병찬,오병렬,김윤식,설인찬 대전대학교 한방병원 2002 惠和醫學 Vol.11 No.1

Gullian Barre Syndrome is an acute symmetric polyradiculoneuropathy that typically presents as a progressive flaccid paralysis. The pathology is believed to be caused by both cellular and humoral immune processes The possibility of death is 3-5% and About 20% of patients require mechanical ventilaton. Recently We have experienced a patient who had suspected Gullian Barre Syndrome for 60days, his condition weakness and pain was impoved through the herb and acupucture Therefore I reported it for the treatment.
