The Neck and Posterior Fossa Combined Penetrating Injury: A Case Report

한현진,정준호,홍창기,김용배 대한신경손상학회 2016 Korean Journal of Neurotrauma Vol.12 No.2

Here we report a case of penetrating neck injury to the posterior fossa that was shown, using high-resolution computed tomography (HRCT) and digital subtraction angiography (DSA), to involve no vascular injury. A 54-year-old man was brought to the emergency department after a penetrating injury to the left side of the posterior neck and occipital area with a knife. He was in an intoxicated state and could not communicate readily. On initial examination, his vital signs were stable and there was no active bleeding from the penetrating site. Because of concern about possible injury to adjacent vessels, we performed HRCT and DSA sequentially, and identified that the blade of the knife had just missed the arteriovenous structures in the neck and posterior fossa. The patient was then transferred to the operating room where the knife was gently removed. Further careful exploration was performed through the penetrating wound, and we confirmed that there were no major injuries to the vessels and neural structures. Postoperative computed tomography revealed that there was minimal hemorrhage in the left cerebellar hemisphere. The patient made a full recovery without any neurologic deficit. In this case, HRCT is a suitable tool for the initial overall evaluation. For the evaluation of vascular injury, DSA can be a specific and accurate tool. Mandatory exploration widely used for penetrating injuries. After careful preoperative evaluation and interpretation, simple withdrawal of material can be a choice of treatment.

다시 쓰는 역사와 리얼리티 : 샐먼 루시디의 " 자정의 아이들 "

The use of historical material in imaginative writing is part of the development of literary genres before the novel. The confusion of fiction and history is most evident in recent fiction through extended metaphor rather than statement. The blurring of fact and fiction in much postmodernists as Salman Rushdie, Graham Swift, Julian Barnes and John Fowles helps us to foster a new sense of history, reality. As reality is a question of perspective, it changes according to world's complexity. The further we are from the past, the more concrete and plausible it seems. On the other hand, as we approach the present, it inevitably seems more and more incredible. It becomes clear that the illusion itself is reality, under the historical and cultural cycle that cannot be viewed as complete. The illusion of perception is scattered to accept the reality of what is being seen. Rushdie in his $quot;Midnight's Children$quot; destabilizes a wide variety of techniques and ofers alternative readings of reality. The history of Saleem Sinai, nanator, is a pastiche of populous and multicultural Mother India. The names of references slide from context to context. Actions echo across this text to others. Meaning interpenetrates. Form cannot be avoided, though it seems tenuous. The whole is filmy. Cinematic discourse provides the illusion of visual representation. The visual images of this work are described in language, not pictorially. These images are often used as a reference to a reality wherein situations and characters are fixed and specific. They teach us to read the techniques that bring this book to life. One of his techniques for creating a whole world is to use film vocabulary. In this way he seeks to provide a sense of continuity of both content and form, so that the disparate events in his life appear to have a sequence.

This study is concerned with educational services provided for archives with a focus on programs for teachers and students in the classroom. The purpose of this study is to develop the archival-resource based learning model. And the other purpose is to find out the influence of the archival-resource based learning. The researcher and teachers designed two lessen plans for archival-resource based learning and general learning. To compare with the archival-resource based learning and the general learning, the researcher divided into two comparison classes of 6th graders of two elementary schools. Statistical analysis was conducted by analysis of covariance using SPSS WIN 12.0 for t-test. 본 연구에서는 교실에서의 교사와 학생을 대상으로 한 기록정보서비스에 대해서 살펴보았다. 이 연구의 목적은 기록물을 자원기반학습에 적용하여 실제로 교육현장에서 활용할 수 있는 방안을 제시하고, 그 효과를 알아보는 것이다. 이를 위해 교사집단과의 협력작업을 통해 기록-자원기반학습 모형을 개발하였다. 그리고 이를 적용한 교수학습안과 일반적인 교수학습안을 개발하여 초등학교 6학년 수업에 적용함으로써 그 효과를 알아보았다. 기록-자원기반학습의 효과에 대한 검증은 SPSS WIN 12.0을 사용하여 t-검증을 실시하였다.

Optimal Treatment Decision for Brain Metastases of Unknown Primary Origin: The Role and Timing of Radiosurgery

한현진,장원석,정현호,박용구,김해유,장종희 대한뇌종양학회 2016 Brain Tumor Research and Treatment Vol. No.

Background Up to 15% of all patients with brain metastases have no clearly detected primary site despite intensive evaluation, and this incidence has decreased with the use of improved imaging technology. Radiosurgery has been evaluated as one of the treatment modality for patients with limited brain metastases. In this study, we evaluated the effectiveness of radiosurgery for brain metastases from unknown primary tumors. Methods We retrospectively evaluated 540 patients who underwent gamma knife radiosurgery (GKRS) for brain metastases radiologically diagnosed between August 1992 and September 2007 in our institution. First, the brain metastases were grouped into metachronous, synchronous, and precocious presentations according to the timing of diagnosis of the brain metastases. Then, synchronous and precocious brain metastases were further grouped into 1) unknown primary; 2) delayed known primary; and 3) synchronous metastases according to the timing of diagnosis of the primary origin. We analyzed the survival time and time to new brain metastasis in each group. Results Of the 540 patients, 29 (5.4%) presented precocious or synchronous metastases (34 GKRS procedures for 174 lesions). The primary tumor was not found even after intensive and repeated systemic evaluation in 10 patients (unknown primary, 34.5%); found after 8 months in 3 patients (delayed known primary, 1.2%); and diagnosed at the same time as the brain metastases in 16 patients (synchronous metastasis, 55.2%). No statistically significant differences in survival time and time to new brain metastasis were found among the three groups. Conclusion Identification of a primary tumor before GKRS did not affect the patient outcomes. If other possible differential diagnoses were completely excluded, early GKRS can be an effective treatment option for brain metastases from unknown primary tumor.

ToA 기반 RSS 보정 센서노드 거리 측정 방법

한현진,권태욱,Han, Hyeun-Jin,Kwon, Tae-Wook 한국정보처리학회 2009 정보처리학회논문지 C : 정보통신,정보보안 Vol.16 No.5

오늘날 무선 장비들이 센서네트워크를 비롯한 매우 다양한 분야에서 광범위하게 사용되고 있다. 무선으로 연결된 센서들은 다양한 임무 수행을 위하여 많은 분야에서 활용되고 있다. 이런 임무를 수행하는데 있어 각 센서의 위치정보는 매우 중요한 시스템 관리의 요소가 된다. 센서노드간 거리 측정은 신호의 도착시간차(Time of Arrival; ToA), 신호세기(Received Signal Strength: RSS), 신호각도(Angle of Arrival: AoA)에 기반을 둔 방법 등이 있다. 무선 센서네트워크에 배치되어 있는 각 센서노드간 정확한 거리 식별을 위해 기존의 거리 측정 방법을 보완하여 거리 오차를 줄이는 ToA기반의 RSS보정 방법을 제안한다. 구체적으로 초음파를 통한 거리측정 값에 맵(RF-MAP)을 통해 보정한 RSS값을 가중치로 보정하여 기존의 거리 측정 방법보다 측정오차를 감소시킬 수 있었다. 실험을 통해 본 연구 방법이 기존 ToA보다 실내($5m{\times}7m$)에서 평균 0.1cm, 실외($10m{\times}10m$) 평균 0.6cm 측정 오차를 줄일 수 있음을 확인 할 수 있었다. Nowadays, wireless infrastructures such as sensor networks are widely used in many different areas. In case of sensor networks, the wirelessly connected sensors can execute different kind of tasks in a diversity of environments, and one of the most important parameter for a successful execution of such tasks is the location information of each node. As to localization problems in WSNs, there are ToA (Timer of Arrival), RSS (Received Signal Strength), AoA (Angle of Arrival), etc. In this paper, we propose a modification of existing ToA and RSS based methods, adding a weighted average scheme to measure more precisely the distance between nodes. The comparison experiments with the traditional ToA method show that the average error value of proposed method is reduced by 0.1 cm in indoor environment ($5m{\times}7m$) and 0.6cm in outdoor environment ($10{\times}10m$).
