Thoracic surgery may be greatly facilitated by causing selective atelectasis of the lung being operated on (one-lung ventilation anesthesia). But the tube used for one-lung ventilation is greater outer diameter than conventional endotracheal tube when compare to each other with same inner diameter, so in some young children it is impossible to one-lung ventilation using double lumen tube or bronchial blocker tube because of narrow vocal cord. We performed one lung ventilation anesthesia using conventional endotracheal tube and Fogarty catheter as a bronchial blocker in 11-year old women who received lung biopsy surgery and left lower lobectomy.

At the confluence of the superior, anterior, and middle mediastinum are the middle portion of the superior vena cava, the tracheal bifurcation, the main pulmonary artery, the aortic arch, and parts of the cephalad surface of the heart. Tumors in this region can cause compression and obstruction of tracheobronchial tree in the region of tracheal carina even though there is no sign and symptom related to respiratory failure in preinduction period. We experienced airway (tracheal) obstruction due to mechanical compression by mediastinal mass during anesthetic induction. She is 24-year old who had no symptom of respiratory distress in preinduction period.

국방연구개발사업 성과에 대한 귀속 주체 및 제3자 실시방안 연구 -전력지원체계사업을 중심으로-

In the case of national R&D projects, R&D institutions may have intellectual property rights in accordance with the principle of attribution to developers under the Framework Act on Science and Technology, but as an exception to this provision, the nation may retain it if necessary for national security. Accordingly, the IPRs belong to the nation in most of the current defense R&D projects, but there is no standard for judgment on cases which are necessary for national security, and the current law system regulates the weapons system mainly. Under these laws, the force support system projects appear to have a weak basis for the attribution of IPRs to the nation, and the government’s stable procurement plan may be problematic if the R&D institutions own it as in general R&D projects. To solve these problems, we will look at the relevant systems and Bayh-Dole Act and present legislative bills to overcome them with several ways including the third party practice in this study. 국가연구개발사업의 경우 과학기술기본법상 개발자 귀속의 원칙에 따라연구개발기관이 지식재산권을 가질 수 있으나, 이에 대한 예외조항으로 국가 안보상 필요한 경우에는 국가가 이를 보유할 수 있다. 이에 따라 현행 국방연구개발사업은 대부분 지식재산권을 국가 귀속하고 있으나, 현행 법령은국가 안보상 필요한 경우에 대한 판단 기준이 부재하고, 무기체계를 중심으로 규율하고 있다. 이러한 법제하에서 전력지원체계사업은 지식재산권의 국가 귀속 근거가 약한 것으로 보인다. 또한 권리 귀속 주체를 일반연구개발사업과 같이 연구개발기관으로 전환하는 경우 국가의 안정적 조달 방안이문제될 수 있다. 이에 본 연구에서는 관련 국내 제도 및 국방 최강대국이자우리나라의 최우방국인 미국의 바이돌법을 살펴보고, 이를 극복하기 위한방안으로서 제3자 실시를 위한 입법안을 제시하고자 한다.

본 논문에서는 색 정보 분석기법을 이용한 효율적인 CCTV 영상 보안 시스템의 설계 및 구현에 관하여 기 술한다. 기존의 방법에서는 주로 압축 알고리듬과 암호화 기법을 이용하여 데이터 처리 비용을 절감하였다. 그러나 본 논문에는 데이터의 절대량을 감소시키기 위하여 영상 데이터의 중복 요소 제거를 위한 색 정보 분석 기법을 제안 한다. 또한 SSL/VPN 터널링 기법을 이용하여 CCTV 영상 보안 시스템의 성능을 향상 시키는 방법을 제안한다. 본 논문에서 제안하는 방법을 사용하면 대용량 정보의 효율적인 처리 및 보안 문제를 해결할 수 있으며, 구현 결과를 통 하여 처리 대상이 되는 영상 데이터가 대폭 감소됨을 확인하였다. This paper describes the design and implementation of an efficient image security system for CCTV using the analysis technique of color informations. In conventional approaches, the compression and encryption techniques are mainly used for reducing the data size of the original images while the analysis technique of color information is first proposed, which eliminates the overlapping part of the original image data in our approach. In addition, security-enhanced CCTV image security system is presented using SSL/VPN tunneling technique. When we use the method proposed in this paper, an efficient image processing is enable for a mount of information, and also security problem is enhanced. Through the implementation results, the proposed method showed that the original image information are dramatically reduced.

We report a case of intractable spontaneous intracranial hypotension complicated with acute subdural hematoma. A 44 year-old woman presented with severe orthostatic headache, nausea and vomiting for 1 month. Her symptom didn't improve after bed rest, hydration, caffeine and steroid neither after 3 repetitive thoracic epidural blood patch therapy. Moreover, her mentality deteriorated acutely. Brain CT revealed bilateral acute subdural hemorrhage and she took an emergency burr hole drainage operation.

Postherpetic neuralgia is sequelae to a herpes zoster infection. It represents with intractable burning pain, allodynia and paroxysmal lancinating pain. Although various therapeutic modalities have been applied to relieve these pains, no definite remedies have been established. Herein is report a patient with postherpetic neuralgia, treated with combination drug therapy; intravenous ketamine, oral dextromethorphan, anticonvulsant, antidepressant, opioid and nonsteroidal anti-inflammatory drugs. He developed sudden delirium after the third administration of intravenous ketamine, and required 5 days hospitalization to recover from his symptom. Furthermore, he was accidentally found to have an arterial aneurysm of his left middle cerebral artery, which had unruptured.

신경병증성 통증과정의 NMDA 수용체 활성과 칼슘통로 α2δ1 Subunit의 영향

유수봉,임영수,김두식,Yu, Soo Bong,Lim, Young Soo,Kim, Doo Sik 대한통증학회 2009 The Korean Journal of Pain Vol.22 No.3

Background: Several studies have indicated that a nerve injury enhances the expression of the voltage-gated calcium channel ${\alpha}2{\delta}1$ subunit (Cav ${\alpha}2{\delta}1$) in sensory neurons and the dorsal spinal cord. This study examined whether NMDA receptor activation is essential for Cav ${\alpha}2{\delta}1$-mediated tactile allodynia in Cav ${\alpha}2{\delta}1$ overexpressing transgenic mice and L5/6 spinal nerve ligated rats (SNL). These two models show similar Cav ${\alpha}2{\delta}1$ upregulation and behavioral hypersensitivity, without and with the presence of other injury factors, respectively. Methods: The transgenic (TG) mice were generated as described elsewhere (Feng et al., 2000). The left L5/6 spinal nerves in the Harlan Sprague Dawley rats were ligated tightly (SNL) to induce neuropathic pain, as described by Kim et al. (1992). Memantine 2 mg/kg (10 ul) was injected directly into the L5/6 spinal region followed by $10{\mu}l$ saline. Tactile allodynia was tested for any mechanical hypersensitivity. Results: The tactile allodynia in the SNL rats could be reversed by an intrathecal injection of memantine 2 mg/kg at 1.5 hours. The tactile allodynia in the Cav ${\alpha}2{\delta}1$ over-expressing TG mice could be reversed by an intrathecal injection of memantine 2 mg/kg at 1.5, 2.0 and 2.5 hours. Conclusions: The behavioral hypersensitivity was similar in the TG mice and nerve injury pain model, supporting the hypothesis that elevated Cav ${\alpha}2{\delta}1$ mediates similar pathways that underlie the pain states in both models. The selective activation of spinal NMDA receptors plays a key role in mediating the pain states in both the nerve-injury rats and TG mice.

현재 구성 되어있는 방범 CCTV시스템에서 네트워크를 통하여 전송되는 구간에 도청이나 해킹이 발생하게 된다면 카메라로부터 전달되는 정보의 보호에 매우 취약하다. 이러한 문제점을 해결하기 위하여 본 논문에서는 SSL/VPN 터널링 기법을 이용하여 CCTV에서 영상정보를 보호하기 위한 SSL 통신메카니즘을 제안하고, 제안한 방법을 기본으로한 보안 시스템의 설계 및 구축에 관하여 기술한다. 관제센터단에서 사용할 VPN Server는 Linux System O/S 인 Fedora 8 버전에서 개발하였으며, 현장단에서 사용될 VPN Client는 ARM9 기반의 프로세서를 탑재한 임베디드 보드상에서 구현한다. 시스템 소프트웨어 구현을 위한 라이브로리는 OpenSSL과 PPTP와 PPP를 사용하였다. If there are some problems such as hacking and revealing of personal information in the existing the CCTV system which is transmitted through the network system, the protection of information passed from the camera is very vulnerable. To resolve these problems, this paper first presents SSL communication protocol for protection image data based on SSL/VPN tunnelling technique, and then the design and implementation of the CCTV security system is described based on the proposed protocol. A VPN Server has been implemented in software on the Linux System, which will be added the control center of the proposed security system. Also, VPN Client which will be used in the setup-box has been implemented on embedded boards with ARM9-based processor. The libraries such as OpenSSL, PPTP, and PPP are used for implementing system software.
