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.

Background & Purpose : Dynamic susceptibility contrast MR imaging, one method of perfusion MRI, was developed to define cerebral hemodynamic status with good anatomical resolution. The authors investigated hemodynamic parameters using this imaging method, in an effort to identify hemodynamic changes on the remote crossed cerebellum of patients with a supratentorial infarct. Methods : Dynamic susceptibility contrast MR imaging was performed in 15 patients with only unilateral supratentorial infarcts. Imaging was obtained at the anatomic level of the cerebellum. rCBF, rCBV, MTT and TP were determined over both cerebellar hemispheres of interest. Results : The rCBF and rCBV values of the contralateral cerebellar hemisphere were significantly more decreased than those of the ipsilateral cerebellar hemisphere in 12 patients(p=0.028, 0.033). MTT and TP values of the contralateral and ipsilateral cerebellar hemispheres didn't reveal any differences(p=0.130, 0.121). Conclusions : The results of this work suggest that the region which are remote from the ischemic brain lesion shows no changes of MTT or TP but show decrease of rCBF and rCBV, mean to diaschisis, it also demonstrates that perfusion MRI is an easily available method to evaluate the hemodynamic status of the brain.

In spite of the fact that the system of oriental medicine still remains in the realm of 'unproven-method of treatment', no one can deny that the oriental medicine is a rich source of idea and motivation for the discovery of new drug from natural sources. However, non-scientific, mystic hypothetical system of oriental medicine refuses to be revealed scientifically. For the purpose of drawing useful parameters for inductive reasoning of the system, a new approach which comprises statistical analyses of prescription was attempted in this study. One hundred and thirty two ginseng-compounds prescription in 'Bang-Yak-Hap-Pyon', one of the most popular formularies of oriental medicine in Korea, were analysed by multivariate analysis technique. The results revealed ginseng from many points of view, e.g., therapeutic indications, dose, and compatibility, etc. Among these, the most striking coincidence with scientific achievements of modern pharmacology, is the fact that the oriental medicine has characterized ginseng already from remote ancient times as neither a specific curative nor an aphrodisiac, but a non-specific adaptogenic drug for general infirmity.

It is expected that fully-implantable middle-ear hearing devices (FIMEHDs) will soon be available with the advantages of complete concealment, easy surgical implantation, and low power operation to resolve the problems of semi-implantable middle-ear hearing devices (SIMEHDs) such as discomfort of wearing an external device and replacement of battery. Over the last 3 years, a Korean research team at Kyungpook National University has developed an FIMEHD called ACRHS-1 based on a differential floating mass transducer (DFMT). The main research focus was functional improvement, the establishment of easy surgical procedures for implantation, miniaturization, and a low-power operation. Accordingly, this paper reviews the overall system architecture, functions, and experimental results for ACRHS-1 and its related accessories, including a wireless battery charger and remote controller.

We developed the system that enables patients to be treated at home during their daily life through digital telemetry and public communication line. This system records and transfers ECG signals through wireless digital telemetry unhindering the patient's normal activities in long-term recording, and transmits the processed data, which enables real-time remote examination via ISDN phone line. Patient's image, voice, and transmitted signals are transferred to medical experts in remote medical center interactively.

In brachytherapy of uterine cervical cancer using the high dose rate remote afterloading system, it is of prime importance to determine the position of the radiation sources and to estimate the irradiation time. However, calculation with manual method is so time consuming and laborious, that authors designed a software as an aid to intracavitary radiotherapy Planning using the personal computer to obtain the precision of treatment without being too complicated for routine use. Optimal source arrangement in combination with dose rate at each specific points and irradiation time can be easily determined using this software in several minutes.

Sciatic nerve can be injured by various mechanism such as compression, traction during surgery, and direct trauma. This case reports a sciatic neuropathy caused by compression due to hematoma occurring after intramuscular injection in the gluteus medius muscle far from the nerve. In order to avoid occurrence of sciatic neuropathy after buttock injection, the injection was made in the upper outer quadrant of the buttock, but sciatic neuropathy occurred. Sciatic neuropathy can be confused with lumbar radiculopathy, so differential diagnosis is important.

A head-and-neck phantom was designed in order to evaluate remotely the quality of the delivery dose of intensity modulated radiation therapy (IMRT) in each institution. The phantom is homogeneous or inhomogeneous by interchanging the phantom material with the substructure like an air or bone plug. Monte Carlo simulations were executed for one beam and three beams to the phantom and compared with ion chamber and thermoluminescent dosimeter (TLD) measurements of which readings were from two independent institutions. For single beam, the ion chamber results and the MC simulations agreed to within about 2% TLDs agreed with the MC results to within 2% or 7% according to which institution read the TLDs. For three beams, the ion chamber results showed -5% maximum discrepancy and those of TLDs were $+2{\sim}+3%$. The accuracy of the TLD leadings should be increased for the remote dose monitoring. MC simulations are a valuable tool to acquire the reliability of the measurements in developing a new phantom.

Haedae(海帶, haidai) is representative herb from seaweeds, but its origin is still confusing. Thus we analyzed its origin on the basis of classics of oriental medicine. The scientific name of Haedae corresponds to Zostera marina, according to the folkloric use. But, it is Laminaria japonica, according to its habitat, morphological feature, and the korean name on the medical books in Joseon since 17c. In the remote past, it seemed that two groups were segragated by the name of Zostera marina Haedae and Laminaria japonica Haedae. However, it is thought that this two trends were mixed up when medical knowledge was compiled in Song Dynasty era. Documental support inclined to Laminaria japonica, but it is too early to conclude that Laminaria japonica is the Haedae. To prove this hypothesis, further study is required to investige whether Laminaria japonica or Zostera marina has mentioned efficacies of Haedae used for the treatment of wen, San syndromes, edema, scrofula, etc. And we have need of research that solve the origin problem of Gonpo(Laminariae thallus) on the assumption that Laminaria japonica is Haedae.
