The purpose of this study is to identify the satisfaction with medical services of the disabled elderly who have the highest need for medical services. For this purpose, the effect of health characteristics and medical service characteristics of the disabled elderly on medical service satisfaction was verified. The subjects of analysis were 3,323 persons with disabilities aged 65 or older who were taken from the national survey of people with disabilities in 2017. For statistical analysis, descriptive analysis, correlation analysis, and regression analysis were performed using the SPSS 26.0 program. The results of the study showed as follows. As a result of the regression analysis, gender (β= -.045, p<.05) and residence status (β= -.048, p<.05) among the demographic characteristics as control variables had a statistically significant effect on the level of medical service satisfaction. Among the health characteristics, IADL (β=-.044, p<.05) had a statistically significant effect on medical service satisfaction level. In the case of medical service characteristics, satisfaction with medical facilities and equipment (β = .290, p< .001), medical staff's level of understanding of disability (β = .404, p< .001), health-related service use (β = .182, p<.05) had a statistically significant effect on the level of medical service satisfaction. Based on the results, practical alternatives to ensure health equity in the community medical system were suggested in the discussion to enhance the health management and self-determination capabilities of the disabled elderly.

In this paper, we suggests a algorithms of recognizing the disease region by extracting particular organ from medical image. This method can extract liver region in spite of input image including many organs and charged format by using multi-threshold of feed-back-structure for segmentation liver region, and suggest the recognition of disease region in extracted liver, using multi-neural network structured by RBF and BP, overcoming the defect of single-neural network. The algorithm in this paper is proficient in adaptation for a multi form change of input medical image. This algorithm can be used at tole-medicine through automatic recognition after recognizing of the disease region by real-tire medical Image.

The purpose of this study was to analyze the frequency of use of hospitalization/outpatient care of patients with addresses in Yeongbuk-gu, Gangwon-do to identify the medical demand and status of medical use in Yeongbuk-do. The National Health Insurance Corporation (www.data.go.kr) conducted an analysis of health insurance and medical benefits (inpatient/outpatient) claims data from 2003 to 2017. The order of the highest frequency of chronic disease was ranked from 1st to 60th according to 'Healing Case and %'. In addition, the use of patients at Sokcho Medical Center, the only hospital in the Yeongbuk region, was analyzed at the same time. According to the analysis, the use of outpatient treatment and In-patients in the Yeongbuk area of Gangwon-do is increasing due to chronic non-infectious diseases from the past acute diseases. In particular, it is necessary to expand the functions of schizophrenia and obstetrics and gynecology and to carry out specific health projects necessary for the health care of the local community. Through this, we should improve the quality of life in Yeongbuk, Gangwon Province.

MRI 영상은 뇌의 해부학적 정보와 기능적인 정보를 제공하는 유용한 도구이다. MR 뇌 영상은 2차원 영상뿐만 아니라 3차원 영상도 임상적으로 중요하다. MR 영상에서 뇌영역의 추출방법으로는 형태학적인 방법, 히스토그램을 이용한 방법, 에지 정보를 이용한 방법, 지식 기반을 이용한 방법들이 있다. 본 논문에서는 region growing을 이용하여 MR 영상에서 뇌 영역을 추출하였다. 3차원 가시화를 위하여 오픈 소스인 VTK를 이용하여 Ray Casting 알고리즘으로 구현하였다. 그리고 의료영상에서 사용되는 각종 단면을 3차원 뇌 영상에서 재구성하였다. 256×256 크기의 71 뇌MR 영상 70장을 이용하여 실험하였다. 향후 연구과제로 MR 영상에서 뇌 영역추출방법과 원영상의 전처리 과정의 연구가 필요하다.

실크는 우수한 광택, 촉감, 물성을 바탕으로 하여 인류에 있어 최고의 의류용 섬유로서 널리 이용되어 왔으며 최근에는 생체적합성 등을 활용한 의료용 및 생물공학용 소재로서 응용하고자 하는 연구가 활발히 진행 중에 있다[1-2]. 그러나 실크의 경우 누에로부터 얻어지는 천연섬유로서 합성섬유와는 달리 누에로부터 토사되면서 그 구조 및 형태가 결정되어 고정되는 단점을 안고 있어 의류용 및 산업용 분야로의 활용에 있어 한계가 있다. (중략)

We investigated on the usefulness of MAR algorithm by making a comparison of the CT value between before and after applying the MAR algorithm in dual energy CT, using the various kinds of medical metals, causing the artifact to lead to the low image quality. As a result, the artifact was reduced in most cases (P<0.05); in particular, the artifact was highly reduced (P<0.05) using high density material, like alloy-stainless (reduced by 78.1%) and platinum, for example GDC coil (reduced by 76.1%). The effect of decreasing the Black hole artifact was outstanding in both the alloy-stainless and alloy-titanium (P<0.05). However, in case of GDC coil-a type platinum, white streak artifact was reduced effectively (P<0.05). Therefore, in case of patients who have medical metals inserted, we think that high-quality image information can be provided by decreasing the artifact caused by high density material through MAR algorithm in dual energy CT.

It is very important to extract the heart region in the medical images. In this paper, we present the automatic heart region extraction in the EBT (electron beam tomography) images. We use contrast thresholding, anatomic knowledge, and mathematical morphology to extract the heart region. Using these results, we applied the active contour models (snakes) to search the exact region. We analyzed the experimental results by comparing the results with the results made by medical experts.

In the medical field, applications of plasma are applied sterilize instruments mainly but with the advent of bio-plasma technology, the scope of application is expanding. Recently, In addition, high-density miniaturization with handheld is required for sophisticated procedures when irradiated directly or treated with non-standard conditions. Rosen-type PZT is a device with a structure that generates high voltage plasma by achieving voltage transformation through electro-mechanical coupling using piezoelectric effect.and is used in portable plasma generating devices as an advantage to increase energy density relatively. In this paper, Rosen-type PZT was modeled using equivalent circuits and was carried out and a plasma generating device for medical application was designed and prototype tested. Prototype plasma generating device generates an output voltage of 5.8 kV with 12V input power and is designed to operate at high voltage by applying the half-bridge topology power converter. The results of the study confirmed the availability of various medical devices, such as plasma jets or direct exposure equipment.

PACS(Picture archiving communication system) is a system that enables medical images such as X -ray, CT, MRI, PET to be stored electronically viewed on computer screens so that doctors and other authorized people can access search the information as needed. But if they are not in hospital area for example on holiday or at night, that are not able to access the PACS system instantly. We have to solve this problem for more efficient patient care. So we try to suggest a method that use the PDA system that wireless LAN and CDMA cellular phone are equipped. This system may help to access easier to PACS system regardless of the location and can also attribute the development of telemedicne.

혈액이 이물질과 접촉하면 응고하는 성질은 생명유지를 위해서는 단단히 중요한 일이나, 인공재료를 이용하여 질병을 치료하고자 할 때는 이러한 혈전형성은 장애요인으로 작용한다. 1960년대부터 최근까지 항혈전성을 가진 재료에 대한 연구가 활발히 전개되고 있는데 그 동향도 조금씩 변모하여가고 있고, 접근해가는 방식이 여러가지로 세분화되고 있다. 여러 논문과 총설, 혹은 서적을 참고로 하면 재료의 분류를 항혈전을 일으키는 메카니즘을 몇가지로 나누고 여기에 포함되는 것들을 열거하는 방식을 채택하고 있다. 한편, 의료에 직접적으로 관여하는 재료는 대부분이 섬유고분자재료가 차지하고 있으며 이분야의 관계자들의 의료에의 공헌도는 아주 높으며 의료 관계자로부터의 기대 또한 크다. 특히 혈액과 접촉하여 혈책적합성을 나타내는 재료또한 대부분이 섬유고분자재료가 차지하고 있기 때문에 섬유고분자재료의 입장에서 이들을 분류하고 각각의 항혈전성 메카니즘과 응용방식의 이해가 우선되어야 할 것이며, 이를 바탕으로 해야 좀더 진보된 형태의 항혈전성 섬유고분자재료의 발달이 가능하리라 본다. 따라서, 이 논문에서는 항혈전성을 나타내는 각각의 섬유고분자들을 그 중심으로 하여 항혈전성 재료를 소개하고자 한다.
