We as a civil investment enterprise have been constructing In-cheon International Airport Railway which is a transportation means to approach In-cheon International Airport. In this alignment, a section between the Seoul station and Ka-joa follows the existing Yong-san line at the center of Seoul city and traverses Seoul subway 2,5,6 lines. So we planned that the alignment would have the shallowest depth to lie under Kyung-eui line and above the airport railroad. The alignment is planned to construct an open-box structure only 3.6m apart from the subway line 5 tunnel structure and construct the open-box structure 0.7m apart from the subway line 2 box structure. In the line planning, we investigated both the security of the existing subway structures during and after construction and the stability and workability between newly structured tunnel structures with three dimensions numerical analysis methods. Also we raised the reliability of design verification which was achieved by specialty society"s review on the planned construction method.

N/A Cervical epidural steroid injection, although not as familiar to many anesthesiologists, can be useful in the management of patients with acute and chronic neck, shoulder and arm pain. My clinic personally contacted and interviewed thirty patients with cervical radiculopathy who re- ceived cervical epidural steroid injection. Twenty seven percent of the patients had a excellent response(greater than 75% improvement) and fifty percent of the patients had a good response (greater than 50% improvement) to an injection of steroid into the cervical epidural space. We have conciuded that cervical epidural steroid injection was very effective in the management of cervical radiculopathy and represented a possible alternative to surgery. Many anesthesiologists should add to their armamentarium the use of such techniques in the man- agement of cervical radiculopathy.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

As a method of testing aptness for a specific regression model, the lack of fit test was employed. Using this method, height-DBH data from 84 plots of Korean White Pine plantation in GaPyung, Kyug-Ki Province were analyzed to examine whether or not a log linear regression model fits well to the given data. A log linear regression model was appropriate for height-DBH relationship of Korean White Pine plantation in GaPyung, Kyung-Ki Province. The resulting prediction model was ln(H)=3.34+14.67 D^(-1). The same linear model could be tarnsformed to the hieght-DBH curve such as H=28.22 e^(14.671D). Using this nonlinear regression model, it could be predicted that Korean White Pine planted in GaPyung locality has the maximum height of 28.22 meters.

홍용신,박은진,김선종,김명래,허성주,박지만 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

In the electrodeposition of copper foil for preparing printed circuit boards, a little amount of gelatin as a addition agent has been used for the better characteristics of a coat of electroplating. Gelatin modifies the physical properties such as mechanical strength, matte-side roughness, ultimate tensile strength(U.T.S), and elongation of copper foil, furthermore gelatin have influence on the structure of electrodeposits and the cathode polarization. The electrolyte used was of a composition; CuSO₄·5H₂O 300g/ℓ, H₂SO₄ 100g/ℓ, NaCl 10 ppm as a brightner, and was gelatin 0-7 ppm as a addition agent. Current density was 50 A/dm², and the temperature of electrolytic bath was 50 to 52 ℃. Experiments showed that the optimum gelatin concentration was 5 ppm with the consideration of the numbers of electrodeposited nuclei. And the nuclei numbers was sharply increased under 5 ppm, but was almostly constant above 5ppm. Average matte-side roughness by Surfcorder was gradually increased with the increasing gelatine concentration up to 2 ppm, and maximum roughness was observed at 2ppm. The roughness showed gradual decrease within the concentration range of 2 to 4 ppm, and was almost constant above 4ppm . Within the gelatine concentration range of 0 to 7 ppm, as the concentration increased, UTS was increased and elongation was decreased logarithmically. Also, in comparison between UTS and elongation, gelatin was identified as an addition agent acting inversely.

중이 진주종상피에서 bcl-2의 발현 양상

용만강,이창수,이주연,이동욱,신시옥 충북대학교 의과대학 충북대학교 의학연구소 2003 忠北醫大學術誌 Vol.13 No.1

연구목적:중이 진주종의 조직학적 특징은 진주종 상피의 과증식과 비정상적인 과각질화 라고 요약되는데 이러한 현상은 진주종 상피를 형성하는 각질세포의 증식, 분화 및 세포 사 멸로 이루어진 세포주기의 항상성 변화로 기인한다. 본 연구는 세포 고사(apoptsis)에 억제작용(inhibition)이 있는 것으로 알려져 있는bcl-2가 중이 진주종에서 발현되는지 알아 보았다. 대상 및 방법:만성 진주종성 중이염으로 수술을 시행했던 환자 10 예에서 중이 진주종 상피를 얻어 western blot analysis를 시행하여 중이 진주종 조직에서의 bcl-2의 발현을 관찰하였다. 결과:Western blot analysis 상 정상 피부 조직과는 달리 중이 진주종 조직에서는 10 예 모두에서 bcl-2가 발현되었다. 결론:이러한 결과는 bcl-2가 중이 진주종에서 과발현 되는 것으로 볼 수 있다. Keratin debris의 축적은 각질세포 사멸현상의 증가에 의한 것으로 세포고사 억제 작용이 있는 bcl-2가 중이 진주종의 병인(pathogenesis)에 중요한 역할을 할 것으로 판단된다. Purpose:The unique pathologic feature of cholesteatoma is known to be accumulation of keratin debris within the middle ear cavity resulting from hyperproliferation and hyperk-eratosis of keratinocyte in the cholesteatoma epithelium. This phenomenon is due to disturbance of the epithelial homeostasis in the cell cycle. This study was designed to identfy the expression of bcl-2 in the cholesteatoma epithelium. Materials and methods:Ten fresh human cholesteatoma tissues and five postauricular skins were obtained from patients undergoing middle ear operations. Western blot analysis was performed for detection of bcl-2 expression on the tissues. Results:Western blot analysis revealed that bcl-2 protein was expressed in all of choesteatoma epithelium specimens, while barely expressed in postauricular skins samples. Conclusion:These findings show that bcl-2 was overexpressed in cholesteatoma epithe-lium. The author suggests that bcl-2 may play a role in pathogenesis of chronic otitis media with cholesteatoma.

신규만,조도상,조용재,김명현,김상진,김성학 이화여자대학교 의과대학 2005 EMJ (Ewha medical journal) Vol.28 No.1

Objectives : Of all the chronic pain syndromes postherpetic neuralgia ranks the most refractory to treatment. The eight postherpetic neuralgia patients have been treated with nerve blocks or neurolysis and obtained good result. We evaluate the therapeutic effect of nerve blocks for postherpetic neuralgia and reviewed the pathology, clinical consideration, treatments and prevention. Materials and Methods : Eight patients with established postherpetic neuralgia enrolled in pain clinic of Mokdong Hospital of Ewha Womans University from March,2004 to December. Average age at 58 and about 63% of patients were over 68 years. Affected area of forehead was two patients. They have been treated with stellate ganglion block (SCB), two times supraorbital and supratrochlear nerves blocks and neurolysis with absolute alcohol. Face affected patient has was one and has been treated with 5 times SGB, 2 times supraorbital and supratrochlear nerves blocks, infraorbital and mental nerves blocks, and then 2times maxillary and mandibular nerves blocks. Chest affected two patients were treated with intercostal nerve blocks. Thoracic wall affected one patient received 2 times thoracic epidural blocks and thoracic nerve block. Scapalur and thoracic wall affected patient has been treated with SGB and 2 times thoracic epidural block. The chest and thoracic wall affected patient received 10 times intercostal blocks,2 times thoracic epidural blocks,3 times thoracic root block and neurolysis of intercostal nerves with absolute alcohol. The injected agents were 1% mepibacaine or 0.25% mercain heavy and methylprednisolone succinated, and at weekly intervals the agents were injected. Results : All patient having been treated with nerve blocks were free of pain at 3-9 months. Conclusion : Although no controlled trial has been done of nerve blocks to treat postherpetic neuralgia, this technique is safe in experienced hands and, if effected, may be repeated. It suggested that local anesthetics and steroid are the effective components in nerve blocks. Data on the relief of acute pain with nerve blocks, however cannot be extrapolated to predict the prevention of postherpetic neuralgia. The best way to prevent herpes zoster becasuse of post herpetic neuralgia is so difficult to treat.
