Objectives : This survey was accomplished to find out how Korean medical doctors take acupuncture treatment in real clinics. Methods : The survey questions were developed by the consensus from the professors who major in acupuncture and moxibustion. The questionnaire was given the 2731 Korean medical doctors at the mending education site; In addition, it was given to 793 doctors working at the 105 Korean medical hospitals listed on the National Korean Medical Hospital Associations Address book by postal mail; and also it was given to the 142 public health care Korean medical doctors who attended the conference for the municipal and provincial representatives of the public health service Korean medical doctors. Total of 1277 questionnaires were retrieved out of the 3666 subjects. Results : 1. Nine hundred out of 1277 Korean medical doctors used method of differentiation syndromes(70.4%) and 1184 out of 1277 Korean medical doctors convalescence decide with subjective symptom improvement of patient(92.6%). 2. Nine hundred eight out of 1277 Korean medical doctors used both local and remote points(71.0%) and 916 out of 1277 Korean medical doctors treat with method of reinforcement-reduction(71.7%). 3. Eleven hundred fifth five out of 1277 Korean medical doctors used cupping a boil(90.3%) and 1023 out of 1277 Korean medical doctors used moxibustion(80.1%). Conclusion : When Korean medical doctors treat with acupuncture, most of them diagnose with differentiation methods and meridian theory, decide convalescence with subjective symptom improvement of patient, select out of both local and remote acupuncture points, treat with method of basic reinforcement-reduction, apply moxa and cupping a boil when they are necessary. The cupping a boil comes to be used when being muscle and joint disease. The moxa comes to be used when being chronic disease.

Purpose: Angiosarcoma is a rare malignant neoplasm of endothelial type cells that line vessel walls. It tends to occur in aged male and the prognosis of angiosarcoma is very poor because of frequent local recurrence and early metastasis. The treatment regimen is yet to be established from its rare occurrence but the wide excision in early stage is known to be the most effective. The authors report two cases of near totally excised angiosarcoma with more than a safety margin of 5 cm. Methods: The two subjects were aged male patients, one of the two was diagnosed with angiosarcoma from our institution confirmed by the biopsy. The other one went through the wide excision with a safety margin of 2 cm and split-thickness skin graft but local recurrence was observed. The two patients underwent near total excision with more than a safety margin of 5 cm, leaving only the periosteum. After confirming that the angiosarcoma had not infiltrated the excision margin, reconstruction with split-thickness skin graft was performed. Results: Based on 6 months and 24 months post-surgery assessment, no local recurrence or remote metastasis in the lungs, liver, bones, and lymph nodes at the neck, where remote metastasis is common, was reported by the two subjects who underwent near total excision with a safety margin of 5 cm. Conclusion: Angiosarcoma has very poor prognosis from its frequent recurrence and metastasis. To enhance the survival rate of angiosarcoma patients, early diagnosis, timely surgical treatment, and radiotherapy after surgery are critical. In addition, authors suggest that it is necessary to further study the efficacy of wide excision using a wider safety margin as much as possible, and to apply this to more cases.

복합위성자료 신호처리기법을 사용해서 남인도양 지역을 중심으로 한 해수면변화와 사행 (meandering)을 연구하였다. 해수면변화는 아프리카 남부(46$^{\circ}$E)에서 크호제트 대지(Crozet basin)의 35$^{\circ}$~46$^{\circ}$S대를 걸쳐서 암스테르담-케르겔른 경로(Amsterdam-Kerguelen Passage)까지 확장된다. 이때 가장 강한 해수면변화(20~30cm)가 2개의 좁은 지역에서 발생하는데, 하나는 경도 49$^{\circ}$~57$^{\circ}$E(약 700Km) 및 위도 38$^{\circ}$~42$^{\circ}$S(약 450Km)나타났고 그리고 나머지 하나는 경도 58$^{\circ}$~64$^{\circ}$E(약 450Km) 및 위도 42$^{\circ}$~44$^{\circ}$S(약 200Km)에서 각각 나타났다. 이것은 해저지형과 관련된 강한 와동류의 형성 때문이다. 와동류 발생지역은 아규라스반류(Agulhas Return Current) 및 남극순환해류(Antarctic Circumpolar Current)와 관련하여 강한 흐름이 형성되는 지역에서 발생했다. 이때 복합위성자료(Topex/Poseidon, ERS1)는 표층순환과 해수면변동 특성을 잘 나타내었다.

소나무의 AIDS라 일컫는 소나무 재선충이 1988년 부산의 금정산에서 최초로 발견되었다. 발견된 이후 2005년 12월까지 경상남도 전역 53개 시군구지역에 피해를 끼쳤다. 피해를 입은 삼림지역에 대한 최선의 대책은 초기 방재 작업 후에 훈증을 통해 처리하는 방법이다. 그러나 관찰에 의해 초기에 방재를 하는 것은 피해 삼림지역이 매우 광범위한 지역에 걸쳐있기 때문에 어렵다. 또한 한국의 지형적 특성 상 관찰자의 접근이 어렵다는 문제가 있다. 본 연구는 근적외선 CCD 카메라를 사용하여 소나무 재선충 피해지역의 초기 방재 가능성을 제시하였다.

Chronic subdural hematomas mainly occur amongst elderly people and usually develop after minor head injuries. In younger patients, subdural collections may be related to hypertension, coagulopathies, vascular abnormalities, and substance abuse. Different techniques can be used for the surgical treatment of symptomatic chronic subdural hematomas : single or double burr-hole evacuation, with or without subdural drainage, twist-drill craniostomies and classical craniotomies. Failure of the brain to re-expand, pneumocephalus, incomplete evacuation, and recurrence of the fluid collection are common complications following these procedures. Acute subdural hematomas may also occur. Rarely reported hemorrhagic complications include subarachnoid, intracerebral, intraventricular, and remote cerebellar hemorrhages. The causes of such uncommon complications are difficult to explain and remain poorly understood. Overdrainage and intracranial hypotension, rapid brain decompression and shift of the intracranial contents, cerebrospinal fluid loss, vascular dysregulation and impairment of venous outflow are the main mechanisms discussed in the literature. In this article we report three cases of different post-operative intracranial bleeding and review the related literature.

As the cumulative amount of spent fuel increases, the reliable and effective management of the spent fuel has become a world-wide mission. For this mission, KAERI is developing the Advanced Spent Fuel Conditioning Process (ACP) as a pre-disposal treatment process for spent fuel. Conventional approach to the development of the process and the remote operation technology is to fabricate the process equipment on the same scale as the real environment and demonstrate the remote handling operation using simulated fuel called a mock-up test. But this mock-up test is expensive and time consuming, since the design may need to be modified and the equipment fabricated again to account for the problems found during a testing. To deal with this problem, we developed a digital mockup for the ACP. Also, for an effective utilization of the digital mockup, we developed user interface modules such as the data acquisition and display module and the external input device interface module. The result of this implementation shows that a continuous motion of the manipulator using the external device interface can be represented easily and the information display screens responded well to the simulation situation.

The Advanced Spent Fuel Conditioning Process (ACP), which is a pre-disposal treatment process for spent fuel is being developed at the Korea Atomic Energy Research Institute (KAERI). The ACP equipment is operated in an intense radiation field as well as in a high temperature. Thus, the equipment is designed in consideration of the remote handling and maintenance. This paper describes a Bridge Transported Bilateral Force-Reflecting Servo-Manipulator (BTSM) system, which is being developed to overcome the limitation of access that is a drawback of the mechanical Master-Slave Manipulators (MSMs), which are mounted on the ACP hot cell wall for the operation and the maintenance of the ACP equipment. The BTSM system was manufactured and temporally installed at the mockup to test its performance. The manufactured BTSM system will be installed at the ACP hot cell on June 2005 after the accomplishment of the performance test. The BTSM system consists of four components: a transporter with a telescoping tubeset, a slave manipulator, a master manipulator, and a remote control system. This system will highly increase the volume of coverage for the operation and maintenance of the ACP equipment.

The comparison of Topex/Poseidon sea surface heights and Tide Gauge sea levels was studied in the South Indian Ocean after Topex/Poseidon mission of about 3 years (11- 121 cycles) from January 1993 through December 1995. The user's handbook (AVISO) for sea surface height data process was used in this study Topex/Poseidon sea suface heights ($\zeta$$^{T/P}$), satellite data at the point which is very closed to Tide Gauge station, were chosen in the same latitude of Tide Gauge station. These data were re-sampled by a linear interpolation with the interval of about 10 days, and were filtered by the gaussian filter with a 60 day-window. Tide Gauge sea levels ($\zeta$$^{Argos}$, $\zeta$$^{In-situ}$ and $\zeta$$^{Model}$), were also treated with the same method as satellite data. The main conclusions obtained from the root-mean-square and correlation coefficient were as follows: 1) to Produce Tide Gauge sea levels from bottom pressure, in-situ data of METEO-FRANCE showed very good values against to the model data of ECMWF and 2) to compare Topex/Poseidon sea surface heights of Tide Gauge sea levels, the results of the open sea areas were better than those of the coast and island areas.
