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.

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.

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

Pulpose : Osteeochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and the proximal metaphysis of the tibia, however, is\ occured rarely on the facial skeleton. Tumors of the mandibular condyle are various and rare. so common interest is a little and its clinical symptoms are similar to the others. therefore, early diagnosis is very difficult. In this study, we will present our cases and review the literatures. Patients and Methods: We studied 17 patients(8 males, 9 females) who were diagnosed a osteochondroma of the mandibular condyle in the department of oral and maxillofacial surgery, Pusan National University Hospital. We reviewed the medical records. Results : Patients' mean age was 30.05 years. The sexual distribution is almost same. Twelve left condyles and five right condyles were involeved. The main symptoms was noise and facial asymmetry. Conclusion : Osteeochondroma is a rare benign tumor of the mandibular condyle. The differential diagnosis is difficult. However, using CT and MRI, we diagnosed early the osteochondroma and treated properly. Thus, we presented the cases of the osteochondroma with the literature reviews.

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.

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.

京畿道 加平地域 잣나무의 地方的 材積表 調製에 관한 硏究

신만용 경희대학교 부설 식량자원개발연구소 1991 硏究論文集 Vol.12 No.-

A statistical technique was presented to develop a local volume table for Korean White Pine plantation in Gapyung, Kyunggi Province. For this, the most appropriate regression model form for individual tree volume was first selected from four cadidate models based on the evaluation statistics. Regression coefficents for the selected model were then estimated using OLS. Another regression equation was also developed to represent height-DBH relationship of Korean White Pine for the plantation. The height factor of independent variable in the individual tree volume equation was then substituted by the height curve equation so that the individual volume was finally estimated by DBH only. The resulting local volume table provided relatively accurate volume estimation. However, the volume of smaller DBH class in the table might be overestimated compared with the existing volume table. This fact might result from the lack of sample data used and the site quality of the plantation in terms of tree growth.
