Thiemann's disease is a form of idiopathic avascular necrosis of the immature epiphyses of the phalanges of the fingers and toes. Few cases of Thiemann's disease have been reported because the disease is rare and difficult to diagnose. To the best of our knowledge, magnetic resonance imaging (MRI) findings of Thiemann's disease have not been reported. Here, we report a case of Thiemann's disease diagnosed by typical clinical symptoms and characteristic MRI findings before radiologic bony abnormalities were apparent.

The purpose of this paper is to diagnose the problems of the revision process of the curriculum, and identify the issues in relation to the 7th mathematics curriculum. From the review on the curriculum revision process in Korea, three issues were identified; timing and scale of curriculum revision, research and curriculum revision, and the relationship between the revision of the overall curriculum and that of a subject curriculum. Regarding the mathematics curriculum, the three issues were raised for further discussion; lack of philosophy behind the mathematics curriculum, optimization of mathematics educational content, and differentiated curricula for students of different abilities.

This paper presents a new approach integrated Case-Based Reasoning with Self- Organization Map(SOM) in diagnosis systems. The causes of faults are obtained by case-base trained from SOM. When the vibration problem of rotating machinery occurs, this provides an exact diagnosis method that shows the fault cause of vibration problem. In order to verify the performance of algorithm, we applied it to diagnose the fault cause of the electric motor.

Recently, X-ray chest radiograph is showing a tendency to take an image of digital radiograph so as to diagnose the pathological pattern of chest in a usual. When the radiologist observes the chest image derived from digital radiograph system on the monitor. he feels difficult to find out because of the sensitivity of chest radiograph. It takes amount of time to adjust the proper image for diagnosis. Therefore, we provided the result and the method of the optimal image equalization for image enhancement.

As many industrial systems become more complex, it becomes extremely difficult to diagnose the cause of failures. This paper presents a failure diagnosis approach based on discrete event system theory. In particular, the approach is a hybrid of event-based and state-based ones leading to a simpler failure diagnoser with supervisory control capability. The design procedure is presented along with a pump-valve system as an example.

The muscular variety of congenital ventricular septal defect [Type IV VSD] comprises from 2 to 18% of the total number of patients and has multiple defects. It is difficult to diagnose by usual angiographic study. Out of 116 cases of isolated ventricular septal defects repaired at this hospital in 20 years period from 1959 and to May 8, 1979, 2 cases had muscular defect which was treated through vertical right ventriculotomy without any problems. Single defect was found in both cases and in one case PDA was associated with Type IV VSD.

Neuropathic orofacial pain (NOP) is initiated or caused by a priomary lesion or dysfunction in the peripheral nervous system or the central nervous system. NOP is divided into paroxysmal and continuous by duration of pain. NOP is important for dentists, because they can occur after dental procedures, such as extractions, endodontic treatment, and dental implant insertion. Dentists should have concern about NOP, because it is difficult to diagnose and treat.

Thoracic sound has been widely known as a good method to examine thoracic disease. But, it's difficult to diagnose with correct data according to patient's thoracic position from same patient who has thoracic disease. Therefore, it is necessary to normalize the data for lung sound objectively In this paper, we'd like to detect a useful data for medical examination by applying PCA(Principal Component Analysis) to thoracic sound data and then present a objective data about lung and heart sound for thoracic disease.

최근에 일어나는 해킹 사고의 대부분은 스캐닝 도구를 사용하여 일차적으로 공격하고자 하는 시스템의 취약점 정보를 수집한 다음, 이를 바탕으로 시스템에 대해 공격을 시도하고 있다. 하지만, 대부분의 네트워크 시스템 관리자들은 자신의 시스템의 취약점에 대한 정보 부족과 기술 부족으로 인하여 무방비 상태로 관리하고 있는 실정이다. 그리고 대부분은 스캐닝 도구들은 처음에는 시스템 보안취약점 진단 목적으로 개발되었으나, 해커들에 의해 악용되고 있다. 따라서, 본 논문에서는 보안에 미숙한 관리자도 시스템의 취약점을 쉽게 발견하고 이를 바탕으로 하여 취약점을 보완할 수 있도록 웹 기반에서 시스템 보안 취약점을 진단하는 시스템을 제안하고자 한다.

Inherited muscle diseases are heterogeneous with varying genetic etiologies and present with common symptoms and signs, including weakness, motor developmental delay, and hypotonia. To diagnose these various diseases, a meticulous family and clinical history, physical and neurological examinations, laboratory findings with electromyography, muscle biopsy, and genetic testing are needed. Here, I review several inherited muscle diseases, with a focus on muscular dystrophy in children and its genetics and general management.
