본 논문은 MCL(Minimum Coupling Loss)와 MC(Monte-Carlo) 방법을 이용하여 같은 주파수를 사용하는 ISM(Industrial Scientific Medical) 기기와 무선랜이 공간적으로 인접하여 사용될 경우의 간섭 영향 분석을 통해 ISM 기기로부터 무선랜을 보호하기 위한 보호 거리를 제시하였다. CISPR(International Special Committee on Radio Interference)에서 규정한 ISM 기기의 기준치를 간섭 파워로 설정하여 ISM 기기로부터 무선랜을 보호하기 위한 보호 거리를 산출하였다. 그 결과 최악의 상황을 고려한 MCL 분석시 105 m의 보호 거리와 통계적 간섭 확률을 바탕으로 한 MC 분석시 17 m의 보호 거리가 각각 산출되었다.

It is usual that the medical examination of human body need special knowledpe and equipments. Thus we have to spend Lime and energy on going to special place such as hospital where doctors and equipments are. Which often cause missing a good chance af medical treatment as well as giving us inconvenience. However many simple and convenient equipments were developed for checking our health conditions recently. O-ring test is accepted a3 one of useful methods to examine our heallb conditions. Also the test is recognized as a uscful means to judge, withoul any special equipment and medical knowledge, if some medical substances or foods are beneficial or harmful to our health. However, the judgement may be mcorrect because it depend on doctor's subjective point of view.In this study, we developed an automatic O-ring t a r mach~ne which enable us to check our health conditions objectively and quantitatively. The validity of the idea to develope the machine was proved by experiments.

According to the National Fire Agency, there are 1,810 waste recycling facilities, 2,094 waste treatment facilities, and 223 waste minimization facilities in Korea. Waste fires are characterized by high severity and are prone to reignition, and it is difficult to timely detect them. Waste fires consequently demand many firefighters, equipment, and time to extinguish. Notwithstanding this reality, waste is excluded from the category of special combustible materials in the Act on Installation and Management of Firefighting Systems, 2021 (the Act). Therefore, this study proposes that special combustible materials, including waste, should be incorporated into the Act, that fire detectors and photoelectric smoke detectors should be installed to enable early detection of fires, and that the use of water and foaming agents as firefighting equipment should be enforced.

의료기관에서 진단용 방사선의 이용은 매년 급속히 증가하고 있다. 또한 집단 유효선량도 매년 증가하고 있다. 그러므로 국민에 대한 방사선 피폭을 최대한 적게 낮추어야 하며, 진단용 방사선 안전 관리를 효율적으로 할 수 있도록 제도적으로 확립하여야 한다. 이에 진단용 방사선 안전관리에 대한 법적 규율이 법령체계상 맞지 않거나 내용에 있어서 현실과 괴리가 없는지 문제점을 파악하고 그에 대한 개선 방향을 모색하여 다음과 같은 결과를 얻었다. 첫째, 「의료법」에는 검사·측정기관에 대한 근거 규정도 없고 행정처분에 대한 위임규정도 없다. 그러므로 「의료법」 에 검사·측정기관에 대한 근거 규정과 이들 기관들에 대한 행정처분의 근거 규정을 두어 법적 정당성을 확보해야 한다. 둘째, 진단용 방사선 특수의료장비에 대해서는 「특수의료장비의 설치 및 운영에 관한 규칙」과 「진단용 방사선 발생장치 안전관리에 관한 규칙」을 통합하여 신고 등 행정적 절차를 일원화해야 한다. 셋째, 「진단용 방사선 발생장치 안전관리에 관한 규칙」 상 진단용 방사선 안전관리기준을 위반한 경우에 행정처분 등 제재가 미비된 사항들을 보완할 필요가 있다. 넷째, 의료기관에서 이용하는 진단용 방사선과 치료용 방사선에 대하여 「의료법」과 「원자력안전법」의 이원적인 법령 체계로 규율하는 것은 진단용 방사선 안전관리에 있어서도 효율적이지 못하다. 따라서 진단용 방사선뿐만 아니라 치료용 방사선, 핵의학을 포함한 의료용 방사선 전체를 「의료법」 체계에서 통일하여 규율하는 것이 필요하다고 본다.

한의사 의료영상장비 사용에 대하여 방사선사의 인식도를 알아보고자 대한방사선사협회 영상의학기술학회의 회원을 대상으로 자체적으로 개발한 설문지를 통하여 설문조사를 하였으며 총 응답 515명, 부적격 응답 34명을 제외한 481명의 설문을 바탕으로 연구하였으며 분석한 결과는 다음과 같다. 거주지, 근무기관, 학력에 따른 인식도 차이에서 통계적 유의성을 보이지 않았으나 고학력일수록 포괄적인 의료영상장비의 사용에는 동의하는 경향이 있었다. 그러나 특수의료영상장비의 사용에는 반대하는 경향이 보였다. 성별에 따른 인식도 차이에서는 남성보다 여성에서 한의사 의료영상장비 사용에 대하여 부정적 인식이 큰 것으로 나타났다. 특히 MRI나 CT, 초음파와 같은 특수의료영상장비를 이용하는 것에 대하여 남성보다 부정적인 경향이 나타났으며 이는 통계적으로 유의하였다. 연령에 따른 인식도 차이에서는 한의사의 의료영상장비 사용에 대하여 20~30대는 부정적, 40~50대는 중립적, 60대에서 긍정적으로 나타났으며 모든 문항에서 통계적으로 유의하였다. 근무경력에 따른 인식도 차이에서는 한의사의 의료기기 사용에 근무경력이 오래될수록 긍정적으로 나타났다. 특히 30년 이상의 근무경력에서 가장 긍정적 경향이 나타났으며 이는 통계적으로 유의하였다. 이번 연구를 통해 방사선사의 한의사 의료영상장비 사용의 인식을 알 수 있었으며, 이러한 연구 결과들은 앞으로의 국민 건강증진을 위한 방향성 제시에 기여할 것으로 생각된다.

Planning for the space of the Media Medical Department requires the details about the efficiency of the equipment and the operation in professional sector. For that, as designing, it is necessary to keep communicating with the experts on the technology and the officials from the company producing the equipment. One of the common concerns is not only how to insure enough room for the future extension and the upgrade of the equipment, as concerning the scale of the hospital, but the plan to cover movie cameras. As technology has been developed, despite the fact that machinery tend to be small, it can be possible to require continuously about the concerns of the scale because the camera taking body-picture tend to be much bigger and more complicated than before. Currently used diagnostic media techniques are divided by the method and the feature of the equipment such as Diagnostic X-ray, Ultrasound, CT, MRI, Angiography. The general and special photographing units which are used more than the other diagnostic parts, must be planned not for experiencing any inconvenience and unnecessary risks for the patients and must accept technical requirements. Also, it must be designed not to be seen as a clinic zone, as concerning the psychological stability of the patients. However, study of the general and special photographing units among the domestic general hospitals is insufficient. Also, as there is shortage of the material considering the development of the equipment, when planning, it's involving a lot of difficulties. Thus, this study has got a purpose on giving the basic material which is essential for further study, as suggesting the planning guidelines and the alternative plans for the general and special photographing units in a general hospital.

CT is a medical device that acquires medical images based on Attenuation coefficient of human organs related to X-rays. In addition, using this theory, it can acquire sagittal and coronal planes and 3D images of the human body. Then, CT is essential device for universal diagnostic test. But Exposure of CT scan is so high that it is regulated and managed with special medical equipment. As the special medical equipment, CT must implement quality control. In detail of quality control, Spatial resolution of existing phantom imaging tests, Contrast resolution and clinical image evaluation are qualitative tests. These tests are not objective, so the reliability of the CT undermine trust. Therefore, by applying an artificial intelligence classification model, we wanted to confirm the possibility of quantitative evaluation of the qualitative evaluation part of the phantom test. We used intelligence classification models (VGG19, DenseNet201, EfficientNet B2, inception_resnet_v2, ResNet50V2, and Xception). And the fine-tuning process used for learning was additionally performed. As a result, in all classification models, the accuracy of spatial resolution was 0.9562 or higher, the precision was 0.9535, the recall was 1, the loss value was 0.1774, and the learning time was from a maximum of 14 minutes to a minimum of 8 minutes and 10 seconds. Through the experimental results, it was concluded that the artificial intelligence model can be applied to CT implements quality control in spatial resolution and contrast resolution.

This study was conducted with whole home care nurses nationwide to provide secondary analyzed data to understand on their usage of medical equipments and their need of them for a month. This study found that treatments given by home care nurses were nelaton catheterization, bladder washing/urethral washing, newborn care, exchange and care for nasogastric tube and suction in that order of frequency. Second, instruments and equipments used for home care were reported to be stethoscope, patient monitor, blood pressure measuring equipment, air flotation mattresses, beds for patients, mattresses, suctioning device sets, enteral feeding equipment and dressing set in that oder of frequency. Moreover, need assessment of medical instruments and equipments showed renal dialysis was most needed and patient monitor, blood pressure measuring equipment, enteral feeding equipment, solution and other supplies for renal dialysis and beds for patient were necessary in that order. In conclusion, the results of this study investigating special treatments and medical instruments and equipments used for home care patients and analyzing patients' need, were expected to be useful for expansion of application of long-term care insurance for the elderly and health insurance as well as for quality control of home care and development of medial instruments and equipments used at home.
