이익모,박순필,김상진,도종웅 中央醫學社 1987 中央醫學 Vol.52 No.12

Ceftezole is a new cephalosporin derivative which was born at Fujisawa research labora-tories on 1975. It. is known as broad-spectrum antibiotics especially sensitive to E. coil, Kleosiella spp. Staphylococcus, Streptococcus, Salmonella, Shigella etc., and known as anti-biotics of wide safety range. To study the clinical effect of ceftezole on the infected patients of neurosurgery, we administered ceftezole as first antibiotics before the microorganisms and sensitivities were identified. The results were as follows: 1) Without the identification of microorganisms and sensitivities, ceftezole was ad-ministered as first drug and there was clinical improvement of 76% of all cases. 2) When we compared microorganisms between the pretreatment and post treatment, S. aureus, E. coil, ?-streptococcus, peptostreptococcus were lightly sensitive to ceftezole. 3) There were no specific side effects on administering ceftezole.

이삼형,이필영,임유종 국어교육학회 2004 國語敎育學硏究 Vol.18 No.-

이 연구의 목적은 한국 아동의 어미 습득에 대하여 밝히는 데에 있다. 어미를 습득하는 첫 단계는 종결어미를 습득하는 것이다. 종결어미의 습득 과정을 보면, 서술형-의문형-명령형-청유형-감탄형의 순으로 습득이 이루어짐을 알 수 있다. 그 이후 비종결어미를 습득하는 과정이 이어진다. 비종결어미는 연결어미와 전성어미로 구분되는데, 두 가지 어미 모두 같은 시기에 출현을 한다. 그러나 비종결 어미의 전형적인 용법의 관점에서 보면, 연결어미의 습득 과정이 전성어미의 경우보다 빠르다. 연결어미의 경우는 대등적, 종속적, 보조적 연결어미로 구분이 되는데, 보조적-종속적-대등적 연결어미의 순으로 습득된다. 전성어미의 경우는 관형형 어미, 명사형 어미로 구분되는데, 관형형 어미-명사형 어미의 순으로 습득이 이루어진다. The purpose of this study is to investigate the process of Korean children's acquisition of final endings. First, children acquire terminal endings, and the order of terminal endings acquisition is a declarative-interrogative-imperativeproposal-exclamative endings. Children, then, continued the acquisition of nonterminal endings. Non-terminal endings has connective endings and transformative endings, and both seem to appear at the same time. However, during a typical use of non-terminal endings, children acquire connective endings prior to transformative endings. Connective endings have three parts; coordinative endings, subordinate endings and subsidiary endings. The acquisition process of connective endings is in the order of subsidiary-subordinate-coordinative endings. Transformative endings are divided into two; adnominal endings and nominal endings. In transformative endings, the sequence of acquisition is adnominal ending-nominal endings.

뇌동맥류 수술시 Fenestrated Clip의 사용에 대하여 : Report of Four Cases

이익모,박순필,김상진,도종웅 대한신경외과학회 1988 Journal of Korean neurosurgical society Vol.17 No.5

Some aneurysms with peculiar shapes, large sized or in unusual location cannot be obliterated by ordinary methods. We present four cases using two kinds of fenestrated clips. There were 4 aneurysms in the 4 patients : 3 saccular and 1 fusiform aneurysm. Two aneurysms were located in anterior communicating artery, one left carotico-opthalmic artery, and one distal middle cerebral artery. All of the aneurysms were successfully obliterated. Our results suggest that the various shape of fenestrated clips may be benefit for clipping difficult aneurysms, which would not be clipped with ordinary one.

One case of multiple intracranial aneurysms is presented. On carotid angiogram, nine aneurysmal sacs including a giant aneurysm of left middle cerebral artery were detected on the right distal anterior cerebral artery, anterior communicating artery, bifurcation of both internal carotid artery, both middle cerebral artery, and left posterior communicating artery. The authors reviewed the literature, and discussed the incidence, determining the site of rupture, and the operative methods of multiple intracranial aneurysms.

외상성 뇌동맥류 : 천측두 동맥에 발생한 외상성 가성동맥류 1예 A Case of Traumatic False Aneurysm of the Superficial Temporal Artery

이익모,김상진,박순필,도종웅,주양자 대한신경외과학회 1988 Journal of Korean neurosurgical society Vol.17 No.1

A case of iatrogenic false aneurysm of the superficial temporal artery is presented. Direct injection of Urograffin into the pulsatile mass showed aneurysmal dilatation, 3×2㎝ sized, of the superficial temporal artery. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature, and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.

박종필,전홍성,김연순,이숙영,김성준 조선대학교 부설 유전생물공학연구소 1992 유전생물공학연구지 Vol.2 No.-

Differaitial centrifugation, sucrose(30%, 60%) and percoll(13.5%, 21% and 45%) density gradient centrifugation were used to effectively isolate mitochondria and mitochondrial DNA (mt DNA) from the leaves of the genus Poncirus (Pondrus trifoliata RAF.) The results showed that percoll density gradient centrifugation provided a convinient and effective method for the preparation of clean mitochondria. The purity of prepared mt DNA was increased by the removal of the nuclear DNA by DNase treatment to the crude mitochondrial suspension mt DNA on the agarose gel was shown extra fluorescent background in case of isolation by differential centrifugation and more cleared band included slightly smeared patterns for sucrose density gradient, and highly paint band from percoll density gradient was appeared to the best results of the above three methods. In addition to chromosomal mt DNAs, two short mt plasmid-like elements were detected in the genus Poncirus. These elements consistently co-purified with the chromosomal mt DNAs and is widely distributed among natrual Poncirus trifoliata RAF. populations. But these elements required proteinase K treatment for mobility in agarose gels.

全南地域 海成粘土의 壓縮指數의 算定에 관한 考察

安鍾弼,李彩奎 조선대학교 국토개발연구소 1988 국토개발연구 Vol.8 No.1

This Study is Senerated to deternine the factors of regression analysis and to compane the values of regression equations and skempton equation Young San River Region and Kwang Yang Gulf Region in Chonnam. Regression analysis was conducted with a personal computer. To determine the factors, We must take the consolidation test in the laboratory, but the test is very difficult and takes long time. So, many repoters have studied to identify the relationship between the compression index and other soil properties besides consolidation test method. In this study, liquid limit was taken as a variable factor and Skempton method was applied to calwlate compression index-Analysis was conducted by region groups and by kinds of soil and by total data. Data gathered from Young San River Region(245). and Kwang Yang Gulf Region(350). The analyzed results for the data have shown that errors between the values of regression equation and Skempton equation are too great to apply Skempton equation to the marine soft clays in Chonnam Region. The range of the error is 30∼50%. As the result of regression analysis. The reliance of regression equation is very poor. For Young San RiverRegion, r=0.43, r^2=0.19, S=4.41×10^-2, C_c=0.0064(LL-39.6). For Kwang Yang Gulf region, r=0.57, r^2=0.33, S=3.7×10^-2, C_c=0.0099(LL-1.13). For total data, r=0.54, r^2=0.29, S=4.08×10^-2, C_c=0.008(LL-20.19) As a result, it will be very careful if skempton method and regression equation are to be applyed to the marine soft clys Chonnam Region. And it must take consolidation test to obtain the exact compression index.

일반적으로 구조물은 외부의 정적 및 동적 하중과 외부환경으로 인하여 피로균열과 부식이 발생하며, 이것은 구조물의 변형을 유발하여 결국 파단으로 이어지기 때문에 균열과 부식의 검출 및 평가와 함께 구조물의 변형에 의한 진동, 변위 기울기와 같은 거동을 감시하는 것도 매우 중요하다. 이에 레이저 센서 시스템을 이용하여 이러한 거동을 측정하여 이상 유무를 모니터링할 수 있는 구조물 안전감시 시스템을 개발하였다. 본 시스템은 2차원으로 배열한 광전센서를 이용하여 구조물의 변형에 의해 유발된 광궤적의 변화를 감시하며 또한 데이터를 취득하고 신호처리 할 수 있는 운용 프로그램도 갖추고 있다. 본 연구에서는 개발한 안전 진단 시스템의 필드 적용에 앞서 실험실에서의 몇 가지 실험을 통하여 그 효용성을 검증하였다. A Safety Monitoring System using a laser and 2-D arrayed photo sensors is developed. To monitor of the deformation and small rotation of structure the developed optical system using 2-D photo sensor array was used to detect the variation of optical orbit of laser which was induced by deformation of the structure. Also, an operating program to manage the system and an algorithm for the data acquisition and the database are introduced. In this study, we demonstrated the capabilities of this system by laboratory experiments before applying the system to the field.

Theoretical analysis and experiment for supersonic flow around the wedges have been conducted. Wedges are being used as a means of measuring a flow direction, Mach No., a basic study of inlet or combustion chamber of ramjet and scramjet engine. We use a shock tunnel to get a supersonic flow conditions and schlieren system to visualize supersonic flow field around wedge. Numerical simulation is also conducted by Harten-Yee type 2nd-order Total Variable Diminishing(TVD) scheme and oblique shock theory. Comparison of calculated results with experimental data is in good agreement.
