본 연구는 와상환자에게 자주 발생하는 낙상, 욕창, 불면증을 영상기술을 통해 인식하여 섬망의 조기진단 모형을 구현한다. 실시간 모니터링을 통해 섬망 잠재환자를 선별하고 집중적인 관리와 치료로 이어질 수 있도록 간호인력을 보조하는 데 주된 목적을 두고 있다. 과활동형 섬망은 파생위험 중 하나인 낙상과, 저활동형 섬망은 원인 요소인 욕창과 묶어 자세인식을 통해 판정한다. 또한 주로 밤에 악화되는 섬망의 특성을 고려해 눈 깜빡임을 통한 불면증 검사를 추가로 반영하였다. 낙상과 욕창을 섬망과 묶어 융복합적인 위험예측 시스템을 구축함과 동시에, 기존의 섬망 사정도구들이 지니는 시공간적 제약을 개선함으로써 간호인력의 부담을 덜어줄 것으로 기대된다.

The integrated medical information system is an effective medical diagnosis assistance system which offers an environment in which medial images and diagnosis information can be shared. Because of the large-scale medical institutions and their cooperating organizations are operating the integrated medical information systems, they can share medical images and diagnosis information. However, this system can only stored and transmitted information without other functions. To resolve this problem and to enhance the efficiency of diagnostic activities, a medical image analysis system is necessary. In this paper, the proposed relationship method analyzes medical images for features generation. Under this method, the medical images have been segmented into several objects. The medical image features have been extracted from each segmented image. Then, extracted features were applied to the Relationship Method for medical image analysis. Several experimental results that show the effectiveness of the proposed method are also presented.

Digital Mammography makes it possible to reproduce the entire breast image. And it is used to detect microcalcification and mass which are the most important point of view of nonpalpable early breast cancer, so it has been used as the primary screening test of breast disease. It is reported that microcalcification of breast lesion is important in diagnosis of early breast cancer. In this study, six types of texture features algorithms are used to detect microcalcification on breast US images and the study has analyzed recognition rate of lesion between normal US images and other US images which microcalification is seen. As a result of the experiment, Computer aided diagnosis recognition rate that distinguishes mammography and breast US disease was considerably high 70~98%. The average contrast and entropy parameters were low in ROC analysis, but sensitivity and specificity of four types parameters were over 90%. Therefore it is possible to detect microcalcification on US images. If not only six types of texture features algorithms but also the research of additional parameter algorithm is being continually proceeded and basis of practical use on CAD is being prepared, it can be a important meaning as pre-reading. Also, it is considered very useful things for early diagnosis of breast cancer.

Sebaceous carcinoma (SC) is a rare malignant tumor, with an estimated incidence of approximately 1 to 2 per 1,000,000 per year. Approximately 75% of SCs are reported to occur in eyelids. Most of these tumors are diagnosed at age 40 or over and exhibit a wide variety of patterns in addition to the general appearance previously reported. SC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. In cases of SC, additional examinations, such as endoscopy and computed tomography, may be necessary because of its association with Muir-Torre Syndrome. We present the case of a 22-year-old Asian man who complained of a rapidly growing chin tumor. The tumor was treated by surgical resection and adjuvant radiation therapy.

Diffuse thyroid disease has ambiguous diagnostic criteria and many errors occur according to the subjective diagnosis of skilled practitioners. If image processing technology is applied to ultrasound images, quantitative data is extracted, and applied to a computer auxiliary diagnostic system, more accurate and political diagnosis is possible. In this paper, 19 parameters were extracted by applying the Gray level co-occurrence matrix (GLCM) algorithm to ultrasound images classified as normal, mild, and moderate in patients with thyroid disease. Using these parameters, an artificial neural network (ANN) was applied to analyze diffuse thyroid ultrasound images. The final classification rate using ANN was 96.9%. Using the results of the study, it is expected that errors caused by visual reading in the diagnosis of thyroid diseases can be reduced and used as a secondary means of diagnosing diffuse thyroid diseases.

Clustered microcalcifications on X-ray mammograms are an important sign for early detection of breast cancer. This paper proposes a computer-aided diagnosis method for the detection of clustered microcalcifications and marking their locations on digitized mammograms. The proposed detection method consists of the region of interest (ROI) selection, the film-artifact removal, the surrounding texture analysis method for the detection of clustered microcalcifications, which is based on the second-order histogram in two nested surrounding regions on the current pixel. This paper also describes the effectiveness of the proposed film-artifact removal filter in terms of the classification performance with the receiver operating-characteristics(ROC) analysis. A three-layer backpropagation neural network is employed as a classifier. The appropriate marking for the locations of clustered microcalcifications can be used to alert radiologists to locations of suspicious lesions.

가격대 성능 비를 고려할 때 저가격으로 병렬시스템을 제작할 수 있다는 특징으로, 시작된 클러스터시스템이 구성 장비의 특수화 및 전체 시스템의 대규모화로 인하여 더 이상 보조적인 소규모 시스템이 아닌, 슈퍼컴퓨터의 한 종류를 이루는 비중있는 시스템으로 자리매김하고있다. 이처럼 클러스터시스템 개발의 전반적인 방향이 대규모화를 지향하는 점을 고려할 때, 각 구성 요소의 무결성, 즉 안정성 점검은 시스템의 정상적인 운영을 위해서 중요한 부분이다. 본 논문에서는 클러스터시스템을 구성하는 각 계산노드의 메모리의 이상 유무을 관리 서버 측면에서 종합적으로 진단하기 위한 관리 도구의 개발을 다루고 있다.

This paper presents a CAD (Computer-Aided Diagnosis) system or detection of breast cancer, which is composed of personal computer, X-ray film scanner, high resolution display and application softwares. There are three major algorithms implemented in the application software. The irst algorithm is the adaptive enhancement of the digitized X-ray mammograms based on the first derivative and the local statistics. The second one is to detect the clustered microcalcifications by using the statistical texture analysis, and the third one is the classification of the clustered microcalcifications as malignant or benign by using the shape analysis. These algorithms were verified by real experiments.

Necrotizing fasciitis is defined as infectious disease showing extensive necrosis of the superficial fascia with widespread involvement of the surrounding tissues and concurrent systemic toxicity. It is found commonly in the extremities, the trunk and the perineum, but shows extremely rare occurrence in the well vascularized area such as head and neck area. Occurred in the head and neck area, it is called "cervicofacial necrotizing fasciitis" (CFNF). It is a fatal disease which carries a mortality rate up to 60%. Early diagnosis, aggressive surgical debridement of necrotic tissues and massive antibiotics therapy are essential for achieving a favorable outcome. We present a case of cervicofacial necrotizing fasciitis in 35-year-old male patient with literature review.
