Five separate incidences of patients with cerebrovascular disease(CVD) were revealed among 555 craniocerebral traumatic victims between 1991 and 1992. The 5 cases of with cerebrovascular disease revealed included 3 aneuryms. 1 arteriovenous malformation and 1 spontaneous intracerebral hematoma caused by angiographic study. The frequent use of computerized tomographic scans in the evaluation of head-injured victims can well demonstrate an intracerebral hemmorrhage, but may not get able to direct the associated cerebrovascular disease;whereas the efficacy of angiography, on the contrary, has been losing its popularity as diagnostic armamentarium. The importance of angiographic study should be considered, if clinical signs and/or brain CT ideate the possibility of cerebrovasular disease even during the course of head injury management.

이원개념을 활용한 도시경관연구경향의 고찰

홍윤순 한경대학교 2003 論文集 Vol.35 No.-

Weltanschauung(world view) has formed the base for the research methodology. Whereas Weltanschauung of north-eastern Asia is regarded as a complementary dualism, the western Weltanschauung can be regarded as a separate and oppositional dualism. Therefore, dualistic thoughts as a strong epistemological methodology show different reasoning viewpoints between western and eastern thoughts. This Study is aimed at investigation of the trends of the urban landscape studies, particularly applied to dualistic concepts. This study has the following implementation. Many researches of urban landscape that have focused on the western methodology have analytic aspects. The perspective that views the city nowadays requires a new paradigm. Therefore, as the methodology of urban landscape this study is suggest a new approach method to the urban planning and design, and management related to the north-eastern Asia's wholistic & relational context.

In the free flap surgery using microvascular anastomosis, angioraphy is widely used as an integral part of preoperative plans. The necessity of angiography is well extablished. But since there exist many controversies regarding adverse effects of angiography. especially there is no concrete evidence about their effects on the patency after microvascular anastomosis, This study attempts to examine the chronological changes of the arterial intima after systemic injection of ionic contrast media sodium iothamate(Talabrix ) and to evaluate its effects on the patency of microvascular anastomosis. Fifty-nine Sprague Dawley rats were divided into 5 groups according to time interval between contrast media injection and microvascular anastomosis. The time intervals were 1 day, 3 days, 7 days, and 14 days after contrast media injection. The ionic contrast media was injected intraveneously through the tail vein. Left inguinal arteries were anastomosed under an operating microscope after the contrast media injection. After the above procedures and reviewing all the results, we can conclude that ionic angiographic dye causes reversible injuries to the vascular intima, and deteriorates patency of the microvascular anastomosis. And we suggest that a time interval more than at least 7 days to 14 days, between anguographic study and flap transfer is requested.

This study attempts to interpret the immanent dualism of the archetype landscape of Hanyang based on Yin-Yang's dualistic structure. The north eastern Asian dualism being different from western analytical dualism, it shows the following relational attitudes. First, others are recognized as essentially pre-requisite for its own existence not as antagonistic. Second, Yin-yang represents the complementarity. Third, Yin-yang is not independent but inter-related elements. Forth, Yin-yang shows not static but dynamic characteristics. Fifth, the concept of Yin-yang is considered as both extreme points of Taegeuk that has holistic characteristics. In this study, the compound dualistic relationships of the archetype landscape of Hanyang are analyzed according to the aspects of physical environment, activity, and meaning. The contents are as follows; mountain and city boundary represent the dualistic relationships of nature and city. In detail, dualism of settlement for living such as outside the fortress and inside the fortress is also found. The dualism showed through land use and arrangement of main facilities is that Jongmyo and Sajik were arranged along the dualistic characteristics since the establishment of Chosun Dynasty and type of settlement was divided into Northern-village and Southern-village. In addition, the meaning of north-south and east-west roads was dualized and main road and sub-road showed the complementary characteristics in the linear surroundings. In the aspects of facilities, dualistic relationships between palace, fortress and gate, Sadaebu house, Hangrang, and general buildings showed dualism of meaning, size, settlement and types. These dualistic characteristics projected from the aspects of physical environment, meaning and activity reflect the detailed characteristics of Yin-yang. It was found that the concept of Yin-yang is compound from architectural environment to urban unit scale. It is implied that the cities in Korea were formed on the basis of inter-relationships and ultimately represented the unification and reconciliation.

韓國 市民社會의 成長過程硏究 : 6공화국까지의 구조변화를 중심으로 Focusing on the Structure Changes up to the 6th Republic

윤순갑,홍철 慶北大學敎 社會科學大學 1998 社會科學 Vol.10 No.-

본 논문은 한국에서 시민사회가 1공화국에서부터 6공화국에 이르기까지 그 기반이 어떻게 축적될 수 있었는가를 파악하고자 했다. 이러한 시민사회의 내적 · 외적인 성장을 국민 총생산과 1인당 GNP의 추이, 교육기관의 설립상황, 노동조합의 조직률, 산업구조의 변동이라는 동일한 변수의 설정을 통해 역대 정권의 흐름속에서 어떻게 구축되었는가를 보고자 하였다. 이러한 분석변수들을 종합해 보면 한국에서 국가와 시민사회와의 관계는 정치적 변화로부터 사회적 변화가 유래한 측면과 사회적 변화로부터 정치적 변화가 촉발된 양 측면이 동시적으로 작용했다고 볼 수가 있다. 결국 5공화국까지의 권위주의적인 국가는 1987년에 6월항쟁을 불러 시민사회에 기존의 민중의 개념을 뛰어넘어 명실상부한 시민의 시대로 넘어가는 계기를 부여했으며, 이를 통해 진정한 시민사회가 개막되었다고 평가할 수 있다. 따라서 저강도 민주주의(low intensity democracy) 체제인 6공화국의 출범은 궁극적으로 시민사회의 성장과정을 6공화국을 기점으로 새롭게 정리해 볼 수 있는 단초를 제공하고 있다. The main purpose of this paper is to figure out how the Korean civil society could accumulate its basis from the 1st Republic to 6th. I examined how the civil society established its foundation in its inner and outer development by setting four identical variables ; (1) the trend of the GNP & the GNP capita. (2) the situation of education institutions, (3) the construction rate of labor unions, (4) the change of the industry structures. The analysis of these variables showed that the relations between state and civil society were caused by both the social change effected by the political and the political change effected by the social. Finally, it may be estimated that the authoritarian governments to the 5th Republic brought the June Demonstration in 1987 and the real civil era beyond the old minjung ideas opened with the Demonstration. Accordingly the starting of the 6th Republic which has the low intensity democracy system provides the new perspective with which the development progress in the civil society can be seen.

Granulocytic sarcoma, a rare extramedullary solid tumor arising from early myeloid precursors, is capable of invading the meninges or the brain parenchyma. The tumor may occur during or after the onset of systemic myelogenous leukemia. On rare occasions, the tumor may evolve before the onset of systemic myelogenous leukemia. Children are affected more often than adults, but sex is not related. Although no definite target area of the brain can be demonstrated, there may be some predilection of the tumor for the posterior fossa. The authors report a case of 4-year-old-boy with granulocytic sarcoma occuring in the posterior fossa presenting with gait disturbance and torticollis. The patient was treated by surgical removal of the tumor, thereby avoiding the potentially lethal complication of a posterior fassa mass. This rare case is reported together a review of the literature.

The scoured and undyed 100% cotton yarn (2/30's) were weft-knitted from 13 different stitches with 7 and 12 machine gauge using a V-bed knitting machine. Structure of knit fabrics was characterized and analyzed: fabric length and width, fabric count, fabric weight per area, and fabric thickness were measured. The thickness of the full cardigan 2✕2 and 4✕4 rib presented the highest values due to usage of tuck stitch. The fabric width of 4✕4, 1✕1, and 2✕2 rib stitches were the narrowest group resulted in relaxation shrinkage after knitting. Also 4✕4rib stitch gave the highest value in fabric density and weight. Fabric stitch and structure were well co-related each other, which give the changes of fabric appearance and properties.

Modernization in our urban history could be expressed as ‘turbulence’. It pursued after the superficial westernization without considering vernacular change and development. As a result, our current urban landscape possesses the many dualistic characteristics. 「Iching」 which had a root in the complementary dualism is the oldest book in north-eastern Asia and has been broadly applied to the academic fields since it includes Yin & Yang’s dualistic structure. Especially, the ’relational context approach’, which is the essence of thoughts in this research had been insufficient. This study tried to develope the interpretational methodology for dualistic realtionships of urban landscape based on the 「Iching」theoty. Iching is so much related to the structuralism, semiology, hermeneutics and phenomenology of Western philosophy. It is also found that humanistic and topologica. aspects of Iching are related to the theory of place and topological landscape researched through the holistic approaches. In addition, Iching had made an attmept to understand the world throught the changing perspectives. This study has set up the framework of dualistic landscape relationships on the basis of changing perspectives. This study has the following implementation. Many researches of urban landscape that have focused on the western methodology have analytic aspects. As the methodology of urban landscape this study introduced Iching which trying to understand the relational context. In addition, this study is expected that the profound understanding of urban environment an detailed relationship through this framework will suggest a new approach method to the urban planning and design, and management related to the future urban environment.

This paper presents a method to reduce hysteresis in multilayer ceramic actuator by connecting the actuator with a capacitor in a series circuit. The change in hysteresis with respect to the capacitor was examined. 0.2Pb(Mg_(1/3)Nb_(2/3))O₃-0.8Pb(Zr_(0.475)Ti_(0.525)) O₃ ceramic material was used as a piezoelectric material for the actuator. Displacement of the actuator was measured in a capacitive gap sensor measuring system. In case of inserting a capacitor in a total circuit, hysteresis became dramatically decreased, and then finally the hysteresis value can be reduced below 0.2%. It was found in this present study that reducing the hysteresis in the actuator is dependent upon the characteristics of the capacitor in total circuit and also operating frequency
