임상실습 교육은 간호이론을 실무에 적용하는 기회를 제공하는 과정으로서 임상실습이 간호교육의 중요한비중을 차지하고 있다는 것은 주지의 사실이다. 이러한 중요성에도 불구하고, 임상실습 교육에 즉각적인 해결이 어려운 많은 문제점이 있음도 이미 알고 있는 사실이다 이에 임상실습 교육의 기초 자료로 활용되고 있는 실습목록표에 대한 간호 학생들의 실습목표의 명확한 이해와 더불어 이론과 실습의 연계성을 강화시키고자 하였다. 성인간호, 모성간호, 이동간호 3개 영역 모두에서 공통적으로 기본임상간호 항목이나 기본간호술과 관련된 항목에서 직접수행의 빈도가 높았고 숙련된 기술적인 처치나 전문성을 필요로 하는 항목에서는 관찰과 수행경험이 부족한 것으로 나타났다. Clinical performance is not only the process of providing the opportunity for applying nursing theory into practice but also it is a well-known fact that clinical performance is an important part in nursing education. lnspite of this importance, it is also true that many problem with no immediate solution exist in clinical performance of nursing students. thus, through measuring and analyzing the degree of clinical experience of the nursing students, on the nursing checklist that is being used as the basic guide in clinical education, we tried to clearly understand the objectives of clinical performance and to emphasize the connection between theory and clinical performance. The results of the study showed that the frequency of directly performing tasks was high in all areas of adult health nursing, maternity nursing, and child nursing for the items of basics clinical nursing and items related with basic nursing techniques, and that the experiences of observation and execution were lacking in the items needing skilled treatment or speciality.

목적: ^(99m)Tc-lactosylated serum albumin (^(99m)Tc-LSA)은 간세포에 특이적으로 결합하는 간수용체 영상용 방사성의약품으로 새로이 합성되었다. 간섬유화를 유발하는 dimethylnitrosamine (DMN)을 투여한 간 손상 휜쥐 모델에서 ^(99m)Tc-LSa의 역동학적인 간섭취를 조사하고 간효소치의 변화와 조직학적 소견을 비교하여, LSA의 간섭취가 간기능의 변화를 반영하는지를 연구하였다. 대상 및 방법: SD계 흰쥐에 DMN를 27 mg/kg으로 복강 내 주사하여 급성 간손상을 유도하고 대조군과 비교하였다. DMN을 주사한 흰쥐를 3일(DMN-3), 8일(DMN-8), 21일(DMN-21)에 ^(99m)Tc=LSA (1,665 mg/kg) 29 MBq를 정맥 주사하여, 30분 동안 동적 영상을 획득하고 간과 신장부위에 관심영역을 설정하여 간과 심장부위의 시간방사능 곡선을 얻었다. 간기능 평가를 위해 시간방사능 곡선을 이용하여 간섭취지수와 혈중제거지수를 구하였고 곡선 최적화를 시행하였다. DMN 투여군과 대조군의 간효소치의 변화와 간조직의 광학현미경 소견을 비교하였다. 결과: 대조군에서는 ^(99m)Tc-LSA가 빠르게 간에 섭취되고 혈중에서 제거되었으나 DMN을 처리한 군에서는 간섭취가 낮았다. 간섭취지수의 비교에서 대조군에 비해 DMN 처리군에서 유의하게 간섭취지수가 낮았다(DMN-3: 0.842, DMN-8: 0.898, DMN-21: 0.91, 대조군: 0.96, p<0.05). 혈중제거지수의 비교에서도 대조군에 비해 DMN 처리군에서 혈중제거지수가 유의하게 높았다(DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, 대조군: 0.473, p<0.05). 비선형 회귀분석에서 R_(2) 값은 0.9이상으로 좋은 일치를 보였고, 대조군에ㅓ K값이 DMN처리군에 비해 크고(DMN-3: 0.28, DMN-8: 0.41, DMN-21: 0.46, 대조군: 0.97, p<0.05), T_(1/2)값은 작았다(DMN-3: 2.5, DMN-8: 1.7, DMN-21: 1.5, 대조군: 0.7, p<0.05). 간효소치의 변화는 DMN-3군에서는 대조군에 비해 상승하였으나 DMN-8, DMN-21군에서는 간효소치의 상승이 관찰되지 않았다. 간조직 소견의 경우 DMN-3군에서 중심정맥 주위에 괴사가 관찰되었으나 DMN-8군, DMN-21군에서는 미약한 정도의 염증세포 침윤만이 관찰되었다. 결론: ^(99m)Tc-LSA 간신티그래피의 간섭취 정도는 간손상과 반비례하였으며 간섭취의 변화는 조직학적 손상이 심한 정도와 간손상후 회복되는 과정을 반영하여 주었다. ^(99m)Tc-LSA 간신티그래피가 간손상을 평가하고 간손상후 회복되는 과정을 추적하는 간수용체 영상용 방사성 의약품으로 사용될 수 있을 것으로 생각된다. Objects: ^(99m)Tc-lactosylated human serum albumin(LSA) is a newly synthesized radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically presented on the hepatocyte membrane. Hepatic uptake and blood clearance of LSA were evaluated in rat with acute hepatic injury induced by dimethylnitrosamine(DMN) and results were compared with corresponding findings of liver enzyme profile and these of histologic changes. Materials and Methods: DMN (27 mg/kg) was injected intraperitoneally in Sprague-Dawley rat to induce acute hepatic injury. At 3(DMN-3), 8(DMN-8), and 21(DMN-21) days after injection of DMN, LSA injected intravenously, and dynamic images of the liver and heart were recorded for 30 minutes. Time-activity curves of the heart and liver were generated from regions of interest drawn over liver and heart area. Degree of hepatic uptake and blood clearance of LSA were evaluated with visual interpretation and semiquantitative analysis using parameters (receptor index : LHL3 and index of blood clearance : HH3), analysis of time-activity curve was also performed with curve fitting using Prism program. Results: Visual assessment of LSA images revealed decreased hepatic uptake in DMN treated rat, compared to control group. In semiquantitative analysis, LHL3 was significantly lower in DMN treated rat group than control rat group (DMN-3:0.842, DMN-8: 0.898, DMN-21: 0.91, Control: 0.96, p<0.05), whereas HH3 was significantly higher than control rat group (DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, Control: 0.473, p<0.05). AST and ALT were significantly higher in DMN-3 group than those of control group. Centrilobular necrosis and infiltration of inflammatory cells were most prominent in DMN-3 group, and were decreased over time. Conclusion: The degree of hepatic uptake of LSA was inversely correlated with liver transaminase and degree of histologic liver injury in rat with acute hepatic injury.

Bae, Kee-Hwa,Yoo, Kyoung-Hwa,Lee, Mi-Hyun,Jeong, Jae-Hun,Choi, Yong-Eui,Yoon, Eui-Soo The Korean Society of Plant Biotechnology 2013 식물생명공학회지 Vol.40 No.3

Iris odaesanensis Y. N. Lee. is an important endangered and native plant belonging to the family Iridaceae in Korea. This study describes a method for rapid micropropagation of this species via from leaf, rhizome and root explants derived calli. Leaf, rhizome and root explants were cultured on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) for callus induction. Rhizome explants yielded calli at a frequency of 72% when cultured at 1.0 mg/l 2,4-D. Calli were maintained at 1.0 mg/l 2,4-D. These calli were transferred to MS medium supplemented with 0, 0.5, 1.0, and 2.0 mg/l 2,4-D in combination with 0, 0.5, 1.0, and 3.0 mg/l BA for adventitious shoot induction. The highest number of adventitious shoot (228.9 per petri-dish) were formed at 1.0 mg/l 2,4-D and 1.0 mg/l BA. WPM medium was the best to convert calli into plantlets, where up to 98.2% of calli were regenerated into plantlets. This in vitro propagation protocol should be useful for conservation of this endangered plant.

Omental infarction, the end result of impaired perfusion to the greater omentum, is a rare benign self-limiting clinical entity. The main clinical symptom is non-specific localized abdominal pain with a moderately raised white blood cell and erythrocyte sedimentation rate. These findings often mimic an abdominal surgical emergency. This condition is often misdiagnosed as acute appendicitis or cholecystitis. The characteristic feature of CT scan and ultrasonography provide non-invasive diagnosis in most patients with omental infarction. We report a case of patient whose CT scan showed the characteristic finding of omental infarction. The patient was improved spontaneously only with conservative care.

Despite the use of aggressive local and systemic treatment including autologous stem cell transplantation in multiple myeloma, extramedullary recurrences are common and the prognosis of these patients is poor. Many novel drugs such as thalidomide, lenalidomide and bortezomib improve the response of treatment of multiple myeloma, but some reports failed to describe thalidomide has effect in extramedullary plasmacytoma. Recent data report on the successful treatment plasmacytomas with bortezomib in patients with advanced multiple myeloma. We treated 4 relapsed or refractory extramedullary plasmacytomas with bortezomib at our institution. We recognized all these extramedullary plasmacytomas decreased and showed more than partial response. This report lends support to the efficacy of bortezomib in the treatment of plasmacytoma and describes the safe use of bortezomib. Responses may, however, be of short duration. Therefore, despite our limited experience, we propose that bortezomib may be considered a therapeutic option for such patients who have risk of radiation therapy

한국 근대사에 있어서 체육에 관한 연구(Ⅱ) : 해방 직후 과도기의 학교체육을 중심으로

이달원,배정행 啓明專門大學 産業開發硏究所 2002 啓明硏究論叢 Vol.20 No.1

본 연구는 해방 직후 과도기 교육과정 속의 체육을 살펴보고자 하였다. 해방 직후 우리나라는 혼란 속에서도 우리 민족선각자들의 민족주의 교육열망과 민주주의에 의한 미군정의 서구적 의식에 의하여 체육이 표면적 발전을 이를 수 있었다. 그러나 당시의 불안정한 시대적 상황과 첨예한 이념의 대치 속에서 그 가치는 혼미를 거듭하였던 것이다. 따라서 현대 체육교육이 바로 서기 위해서는 교육에 대한 완벽한 준비와 교육 본연의 의미를 희석시키는 모든 상황과는 단절할 수 있는 교육의 독립성을 유지하여야 한다는 것이다. This research focuses on physical education of school during the time of transition after liberation. Enthusiasm of old scholar and influence from USA educational pattern, Physical education acquired superficial development. However. Value of physical education under social disorder and ideology conflict were not fully assessed, Preparation and Isolation of education itself are critical to realize true meaning or thought of physical education.

We have investigated the lattice relaxation and crystalline qualities of InGaAs/GaAs heterostructure as a function of the layer thickness. The ?? heteroepitaxial layers were grown by molecular beam epitaxy(MBE).The eqilayer thickness were from 230 Å to 3 ㎛ with composition around ×=0.15. The lattice constants c obtained using double axis diffractometry(DAD) as a function of the layer thickness were constant until 1000 Å. Change in lattice constant of surface normal appeared at the thickness of1200 Å, and it decreased as layer thickness increased. The relaxation of epilayers were from 32% at 1200 Å to 84% at 3 ㎛, and the crystalline qualities of epilayers with increased with increasing thickness.

PC 클러스터링 구조 기반 VOD서버 개발

이정배 부산 외국어 대학교 1999 外大論叢 Vol.19 No.3

Advances in compression, computing power and the development of high-speed networks and high performance storage devices have enabled to deliver multiple simultaneous video streams to many users by networks. The continuous media (CM) data such as audio and video have large size, require real time property that are displayed periodically. The effective storage and management of CM data is important. The storage servers that support storage and retrieval of CM data should be have high disk and network I/O bandwidth and large memory capacity. Since current disk bandwidths are substantially larger than data rate requirement of isolated video stream, design of a single-user video server is relatively simple. However, the design of scalable multimedia servers that can service thousands of concurrent clients imposes several research challenges. In the recent past, several researches have developed techniques for designing small-scale multimedia servers, in which all the disks are assumed to be connected to a single node. In such servers, however, the node becomes the bottleneck as it cannot sustain the bandwidth requirements of a large number of streams. Consequently, such servers cannot scale to support the number of streams required for high-end Video-on-demand(VOD) type applications. Many of VOD type applications adopt a data sharing model for multiple client requests. Physically shared disks may be used to support such model. However, such shared I/O hardware is typically more expensive than standard disk, limits the number of nodes that can share the data and leads to complicated cabling. The virtual shared disk(VSD) is a software layer that can make a device attached to one node appears as if were directly attached to all nodes. The interface presented to application is the same as for local devices: applications can open, close, read, write and ioctl operations against the VSD. Our testbed system consists of PCs connected by Ethernet, and each PC`s operating system is the Linux. When an application issues a read request against a VSD device, the Operating system invokes the read entry point of the VSD device driver. The read routine validates the arguments, broke a request into multiple smaller requests and looks up the device in the driver`s internal data. Then it determines which node is currently the server for the VSD to which the I/O was issued; the server nod is the node to which the device is physically attached. If the request is for a device served by a remote node, a copy of the request is sent to the remote server. We implemented the VSD functions using IOCTL command and kernel socket routine. This paper is organized as follows. In section 2 we describes the server configuration for concurrent access to shared video data. In section 3 we describes implementation for the basic functions such as buffering, local and remote accesses. In section 4, we evaluate our proposed scheme by performing a series of experiments on a set of video data and compare theirs and theoretical performances. Finally we conclude with a discussion of future work in Section 5.
