  • This paper describes design techniques of general purpose thermal array printer, especially easily applicable to medical measurement equipment. The'general'means that the proposed thermal array printer can be applied to not only medical field but other industrial field by establishing the eligible protocol. The thermal array printer is composed of i)MPU and its peripherals ii)printer head control, iii)diverse protection circuits, and iv)serial communication. In this paper the performance of the proposed thermal array printer was evaluated by applying to an 3 channel electrocardiogram recorder. The propped system can support'Hangul'text as well as alphanumeric characters and any bitmap image.

  • Objectives: The objectives of this study is the examination of physiology of the obesity by automatic bioelectric response recorder. Methods: The 86 patients below BMI 20 and the 144 patients over BMI 25 were objectives. They visited Dongguk University Kangnam oriental medical hospital from 2000. April 1 to 2001 August 30. Results :The patients below BMI 20 were accelerated a parasympathetic nerve and were decelerated a sympathetic nerve, so they loosened the tension, lacked the resistance and were oversensitive. The patients over BMI 25 were accelerated a sympathetic nerve and were decelerated a parasympathetic nerve, so they maintained the tension and the resistance.

  • Objectives: In order to study the effect of the oriental medical therapy on the patients who visited Neuropsychiatry and oriental medical differentiation of symptoms and signs with ABR (Autonomic Bioelectric Response recorder)-2000, these clinical studies were performed. Methods: Sixty six patients with headache were classified into three groups; the first is tension headache, the second is migraine headache, the last is the others, each group was investigated of a various characteristic, the effect of the oriental medical therapy and stress was measured by ABR-2000. Result: 1. According to the statics, the tention headache's rate was higher than migraine; on the whole woman's rate was higher than man's. however in the migraine the rate of sex was equal. 2. According to the cause facter, oversensitiveness, overexertion, dyspepsia, etc. were numorous in the order. 3. According to the oriental medical differentiation of symptoms and signs, the rate of stagnation of the liver-qi' s fire-transmission(肝鬱化火) and deficiency of qi(氣虛), these two types were highest. result of analyzing ABR-2000 is that stagnation of the liver-qi's fire-transmission(肝鬱化火) is the highest stress. 4. According to treatment rate, 80.3 percent of patients satisfied of treatment.

  • Purpose : To research the Skin Resistance Variability(SRV) of premature ovarian failure(POF) patients by Autonomic Bioelectric Response Recorder(ABR-2000 system, Meridian, Korea) and report the specific results in SRV of POF patients. Methods : We measured SRV of 17 POF Patients who came to Conmaul Oriental Medical Hospital during August 2005 ${\sim}$ July 2006 by ABR-2000 system. We analyzed the results which height of graph Part was converted into 0${\sim}$10, and the readings of Low/Normal/High. Results : The mean value of graph height on each(1, 2, 3) part is lower than normal range(4-6) in POF patients. The distribution ratio of Low/Normal/High on each(1, 2, 3) part shows that there are much more Low proportion in POF patients. Conclusion : The low graph height of POF patients on 1, 2, 3 part means that conductivity & capacitance of POF patients is low, especially on head.

  • A low cost, low power, portable cardiac event recorder as a tether-free biological signal processor was developed. Dual channel ECG signals are sampled at 128Hz in 12 bits resolution. Sampled data are continuously recorded in a circular buffer. If event button is pressed, 2 minutes data before and after the event are recorded in 512 Kbyte SRAM. Total 11 events can be recorded. Data can be transferred to PC through RS-232 protocol. It operates for two months by a half AA size 3.6V Lithium battery. The system size is $55\times55\times13[mm^3]$.

  • In this paper, we devised a simple portable digital recorder for a day life ECG signal recording. The system are consisted of ECG amp. part, signal conditioning part. A/D converter, data compression part and digital memory part. An ADPCM algorithm used at data compress part for 50% of data reduction. The maximum lengths of recording times take 3 hours in 1 mega byte memory.

  • In this paper, the patient data back-up system for medical and engineering field was designed. The system consists of 8-bit microprocessor, cassette recorder and data acquisition & control logic. To Inake data reduction, a Marked CORTES Algorythm which can be easily reconstructed was also designed in real time mode. In results, a Marked CORTES Algorythm produced about 35% data reduction rate and reconstructed good original data that are suitable Medician's reading.

  • 최근 인터넷의 중요성으로 보다 다양한 보안 서비스가 요구되고 있다 부인방지 서비스는 새로운 보얀 요구사항이다. 인터넷뱅킹, 증권거래시스템 , 전자의무기록, 전자상거래 등의 많은 어플리케이션은 부인방지 서비스와 관련이 있다. 그러나 통신의 기밀성이나 신원확인에 대한 보안에 비교하여 부인방지에 대한 연구는 부족했다. 이론적으로, 부인방지 프로토콜이 종료되었을 때 발신자가 수산부인 방지증거를 획득하고 수신자가 발신부인 방지증거를 동시에 획득하거나 쌍방 모두 유효한 증거를 획득하지 못하였을 때 공정하다고 정의한다. 기존의 대부분의 부인방지서비스는 신뢰된 제3자인 TIP(Trusted Third Party)를 기반으로 하여 프로토콜의 단계마다 통신에 관여한다. 따라서 TIP는 통신부하를 발생시키는 단점이 있다. 제안하는 전자서명기록기는 논리적으로 부인방지의 공정 성을 보장하연서, 물리적으로 검증서버와 함께 구성하여 네트워크의 부하를 최소화한다.

  • This study was conducted to evaluate the quality in medical records by analyzing its completeness through setting up the level of record on the patient's past history and through examining the actual medial records. Targeting the information on the patient's past history in interns' records, residents' records and nurses' records toward 403 inpatients who were admitted first in 2004 at an university hospital due to stomach cancer. We analyzed whether the charts were recorded or not, recording level, the satisfaction with the expectant level of the records in the hospital targeted for a research and the level of agreement. The results were as follows; first, as for the rate of recording those each items, they were high in the chief complaint & present illness and the past illness history. Depending on the group of recorders, the recording rate showed big difference by items. Second, as a result of measuring the level after dividing the recording level of items for the patient's past history from Level 1 to Level 4 by each item, the admission history, the past illness history, and the family history were about Level 3, and the smoking history, the medication history, the chief complaint & present illness, the drinking history and allergy were about Level 2. In the admission department, it was excellent in the interns' records for the medical department. Third, as a result of its satisfactory level by comparing the expect level of a record and the actual record by item in information on the patient's past history, which was expected by the medical-record committee members of the hospital targeted for a study. And forth, we analyzed the level of agreement with Kappa score in the level of 'Yes' or 'None' related to the corresponding matter in Level 1, in terms of information on the past history in the intern's record, the resident's record, and the nurse's record. The level of agreement in the resident's record & the nurse's record, and in the intern's record & the resident's record was from "excellent" to "a little good". There were differences in the level of completeness and in reliability for the information on the past history by the recorder group or by the admission department. The encounter process that was performed by the admission department or the recorder group, indicated the result that was directly reflected on the quality of medical records, thus it was required further study about the medical record documentation process and quality of care. The items that showed the high recording rate quantitatively were rather low, consequently we'd should develop the tool for the qualitative inspection and evaluate the medical records further. And the items were needed to be detailed in the record level were rather low, and hence there needed to be a documentation guideline and education by the clinical departments.
