본 연구에서는 의료서비스의 복잡한 스케줄링문제 해결을 위한 새로운 시스템을 제안하였다. 기존 FCFS 시스템은 병원의 입장만 고려하였으나 제안 시스템은 병원의 사정과 환자들의 선호시간을 자동협상으로 반영하였다. 본 시스템은 개인의 서비스이용 희망시간을 우선도로 표현하였고 개인이 선택한 협상전략에 따라 변화되는 우선도를 기준으로 스케줄을 조정할 수 있도록 설계하였고 병원의 정책에 따라 스케줄을 확정 할 수도 있게 하였다. 따라서 제안시스템은 장비의 유휴시간만을 고려하는 기존시스템과 달리 장비의 효율성뿐만 아니라 환자의 대기시간까지 고려할 수 있도록 하여 의료서비스의 고객만족경영을 지원할 수 있을 것이다.

Purpose: The purpose of this study was to measure the noise levels in intensive care units (ICUs) and to analyze the causes of the noise and patient perceptions of the noise. Methods: Noise levels were recorded in adult ICUs for 24 h over a week from the patients' bedside with a sound level meter. Noise sources were categorized into three groups: medical equipment, health care providers, and the environment. Noises from the environment were recorded in an empty ICUs side room. Perceptions of the noise of 125 patients admitted to the ICUs were recorded using a questionnaire. Results: The mean level of noise in the ICUs was 58.5 dBA (range: 34.2-80.2 dBA). The causes of noise higher than 70 dBA were nebulizers and infusion/syringe pumps among medical equipment, and drawer slamming, phone ringing, and stripping packages of medical fluids among environmental noises. According to the questionnaire, 64.0% of the patients responded that the ICUs were noisy and that they suffered from sleep disturbance because of the noise. Conclusion: Noise is considerably high in ICUs and is an annoying factor for the patients. Most noise sources are adjustable, and we should try to reduce noise whenever possible to make the ICUs environment more pleasant.

Objectives : This study aimed to investigate the perception level of Telemedicine among Korean medical doctors. Methods : The on-line survey was administered for Korean Medicine doctors. The survey consisted of 46 questions, addressing issues on concepts and adoption model of Telemedicine. Data were collected from 528 Korean medical doctors, and were analyzed using frequency analysis, t-test, ANOVA, and Kruskalwallis test. Results : The results showed that more than half of respondents had positive attitude towards implementation of Telemedicine in Korean Medicine and conventional medicine areas. Respondents were most positive about the aspect that Telemedicine could reduce 'hospital use by people with disabilities', while they were most concerned about the possibility that patients could be concentrated in large-scale hospitals. As prerequisites for the introduction of Telemedicine, accurate information delivery during remote communication between doctors and patients, clarification of responsibility for Telemedicine at the policy level, and development of equipment for accurate information delivery at the technical level received high responses. Conclusions : Korean Medicine doctors were positive about the implementation of Telemedicine, and they preferred to remote monitoring between doctors and patients. The development of medical equipment for accurate patient information delivery and the establishment of an institutional basis for clarifying responsibilities in case of medical accidents are required.

Today, We have used many electronic equipment such as computer, TV, cellular phone and so on. These equipment radiate a large amount of EMI(Electromagnetic interference) which is occurred trouble of airplane, medical equipment, communicate equipment, and especially, human health. So, Ni mesh fabrication for EMI shielding by continuous electroforming process was investigated. Continuous electroforming apparatus was made by means of rotating cathode drum. And We investigated the characteristics of two types of Ni electroforming solution. One was made by laboratory and the other was produced by M cooperation. The grain size increased with increasing current density and bath temperature, and decreasing rotating speed of cathode drum. EDX results indicate that the Ni mesh electroformed by the KIMM solution is composed of pure Ni. But the Ni mesh electroformed by the M cooperation solution has Ni and S element. The incorporation of S element in the Ni mesh has a profoundly effect on mechanical properties such as hardness, internal stress and so on.

IEC 규격은 유럽, 일본 등 해외 여러 나라에서 자국의 규격으로서 이용되고 있으며, 우리나라에서는 현재 산업표준인 KS 형태와 더불어 강제성을 갖는 식품의약품안전청 고시로서도 발행되고 있다. 전자의료기기에 관한 IEC 규격인 IEC 60601 시리즈의 공통규격(IEC 60601-1:2005)이 3판으로 개정됨에 따라, 보조규격과 개별규격 또한 그에 맞추어 제 개정이 필요하다. IEC 규격의 변화 동향을 파악하는 것은 국내 의료기기 제조 수입업체 및 시험검사기관에서 매우 중요하다. 따라서 본 연구에서는, 진단용X선기기와 관련한 3개 규격 IEC 60601-2-44(CT의 기본안전과 필수성능에 관한 규격), IEC 60601-2-45(유방촬영용X선장치의 기본안전과 필수성능에 관한 규격), IEC 60601-2-54(진단용 X선장치의 기본안전과 필수성능에 관한 개별규격)에 대하여 IEC 60601-1의 3판에 맞추어 제 개정된 최신판의 동향 및 특징을 살펴보고자 하였다. 또한 현행 식품의약품안전청 고시가 IEC 60601-1의 2판이 적용된 개별규격을 참고로 하고 있어, 현행 식품의약품안전청 고시와 대비하여 그 특징을 살펴보았다. IEC 60601-1의 3판이 적용된 진단용X선장치 외 2개의 IEC 개별규격의 특징은 다음과 같다. 1) 기계적 위해요인, 특히 움직이는 부분에 대한 내용이 강화되었다. 2) 환자 선량을 표시 및 기록하도록 명시하고 있다. 3) 잠재적인 위험요소에 대해 체계적으로 관리가 가능한 위험관리 프로세스를 도입하고 있다. 4) 과거 Film-Screen System과 더불어 DR system(digital radiography system)에 대해서도 적용하고 있다. 현재 IEC 60601-1의 3판이 적용된 개별규격이 식품의약품안전청 고시로 개정될 예정이므로, 국내 시험 검사기관 및 의료기기 제조 수입업체 등에 유용한 자료가 되기를 기대한다.

High price equipment is one of the major factors that increases national health expenditure in developed countries. Computerized Tomography(CT), one of the important high price equipment, has been concerns of health service researchers and policy makers in many countries. In Korea, CT, first introduced in 1984, have spreaded nationwide with rapid speed. Though the Committee for Approving Import of High Price Medical Equipment, founded in 1981, tried to regulate the introduction of high price medical equipment including CT, the effort resulted in failure. The exact situation of diffusion of the high price equipment, however, was not yet investigated. We aimed at the description of the diffusion of CT in Korea and analysis of influencing factors on hospitals for the adoption of CT. We mainly used the database of CT, made in 1996 by the National Federation of Medical Insurance for the purpose of insurance payment for CT. Also characteristics of hospitals were gathered from yearbooks published by the central and local governments and by the Korean Hospital Association. We calculated the cumulative number of the CT per one million population year by year. In turn, multiple linear logistic regression was done to find out the contributing factors for the adoption of CT by each hospital. In the logistic regression model, it is regarded as dependent factor whether a hospital retained CT or not in 1988 and 1993. The major categories of the independent factors were hospital characteristics, environmental factors and competitive conditions of hospitals at the period of the adoption. The results are as follows: Number of CT scanners per one million persons in Korea marked more higher level compared with those of most OECD countries. Major influencing factors on the adoption of CT scanners were hospital characteristics, such as hospital referral level, and competitive condition of hospitals, such as number of CT scanners per 10,000 persons in each district where the hospital was located. In Korea, CT diffused with rather rapid speed, comparable with those of the United States and Japan. The major factors contributing on the adoption of CT for hospitals were competitive condition and hospital characteristics rather than regional health care need for CT. In conclusion, a kind of regulating mechanism would be necessary for the prevention of the indiscreet adoption and inefficient use of high price equipment including CT.

본 논문은 2.3 GHz 대역을 사용하는 ISM(Industrial Scientific Medical) 기기가 동대역을 사용하는 WiBro 서비스에 미치는 간섭 영향을 분석하여 ISM 기기로부터 WiBro 서비스를 보호하기 위한 보호 거리를 산출하였다. 간섭 시나리오로 ISM 기기의 간섭 파워는 CISPR(International Special Committee on Radio Interference) 11의 전계강도 기준치를 적용하였고 WiBro 수신기가 ISM 기기로 근접하는 경우를 구성하여 분석하였다. 그 결과 최악의 상황을 고려한 MCL(Minimum Coupling Loss) 분석시 14 m의 보호 거리와 통계적 간섭 확률을 바탕으로 한 MC(Monte Carlo) 분석시 간섭원의 수가 1개 일 때 간섭 확률 5 %를 만족하기 위해 10 m의 보호 거리가 각각 산출되었다.
