The terminology used for oriental medicine has not yet been standardized so far and this might cause the problems in developing theories and clinical research of oriental medicine. To establish scientific backgroupd of oriental medicine, it is required that all the terminology used for oriental medicine should be standardized and unified. For more efficient oriental medical practice, the standardization, unification of the terms and conditions used for diagnosis in oriental medicine should be achieved. The aim of this study are as follows; 1. To provide clear and logical systems for the diagnosis of symptoms and diseases. 2. To provide the theoritical clearmess of oriental medicine and to promote the public facilities for study. 3. To provide ways of idea exchange and understanding between oriental medicine and various biological sciences. 4. To provide practical basis for hospital administration for oriental medicine.

Purpose: The clinical outcomes were investigated to determine if arthroscopic management is a useful method for 19 hips with iliopsoas tendon impingement (IPI) after total hip arthroplasty (THA). Materials and Methods: Eighteen patients (19 hips), who complained of groin pain and flexion pain that persisted after THA from September 2013 to December 2019, were the subjects of this investigation. The mean time to manifestation after THA was four months (range, 1-9 months) in patients of an average age of 60 years (range, 50-69 years). Thirteen out of 18 patients underwent THA using the direct anterior approach and five by the lateral approach. IPI was diagnosed by the medical history, physical examination, blood test, radiographic examination using X-ray and computed tomography, and topical injection therapy. All patients underwent arthroscopic treatment and a dynamic arthroscopic physical examination after exposure to the iliopsoas tendon revealed impingement. Tenotomy was then performed on the muscle portion through the total tendon portion. Symptoms and pain levels of preoperative, postoperative and follow-up period were investigated and compared. Results: The Western Ontario and McMaster Universities Osteoarthritis Index score decreased from an average of 58.4 (range, 40-88) before surgery to an average of 35.0 (range, 15-76) after surgery. Similarly, the visual analogue scale decreased from an average of 4.0 (range, 2-6) before surgery to an average of 1.4 (range, 0-4) after surgery. Sixteen patients (88.9%) showed pain relief and improvement in the straight leg raise test, and two patients showed postoperative muscle weakness and sustained pain. In the follow-up period, muscle weakness improved. One patient underwent arthroscopic iliopsoas tenotomy at the lesser trochanteric level but the symptoms persisted. The clinical symptoms were improved after one more tenotomy at the joint level. Conclusion: Arthroscopic iliopsoas tenotomy performed in patients with IPI after THA showed good clinical results.

The huge and complicated plants such as nuclear power stations are likely to cause the operators to make mistakes due to a variety of inexplicable reasons and symptoms in case of emergency. Thats why the prevention system assisting the operators is being developed for. First of all. I suggest an improved fuzzy diagnosis. Secondly. I want to demonstrate that a classification system of nuclear plants accident investigating the causes of accidents foresees possible problems. and maintains the reliability of the diagnostic reports in spite of improper working in part. In the event of emergency in a nuclear plant, a lot of operational steps enable the operators to find out what caused the problems based on an emergent operating plan. Our system is able to classify their types within twenty to thirty seconds. As so, we expect the system to put don the accidents right after the rapid detection of the damage control-method concerned.

There have been active research activities to use neural networks to analyze OCT images and make medical decisions. One requirement for these approaches to be promising solutions is that the trained network must be generalized to new devices without a substantial loss of performance. In this paper, we use a deep convolutional neural network to distinguish AMD from normal patients. The network was trained using a data set generated from an OCT device. We observed a significant performance degradation when it was applied to a new data set obtained from a different OCT device. To overcome this performance degradation, we propose an image normalization method which performs segmentation of OCT images to identify the retina area and aligns images so that the retina region lies horizontally in the image. We experimentally evaluated the performance of the proposed method. The experiment confirmed a significant performance improvement of our approach.

PFAPA (periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis) syndrome is one of the causes of periodic fever in pediatrics with unknown etiology. It is characterized by abrupt onset of fever, malaise, aphthous stomatitis, pharyngitis and cervical adenitis without long-term sequelae. Laboratory findings of this sporadic and nonhereditary syndrome are so non-specific that the diagnosis is based on clinical findings. Oral prednisolone is quite effective in controlling the symptoms. We report a case of a 6-year-old girl who was diagnosed as having PFAPA syndrome after 2 years of episodes, by excluding other disease entities with similar clinical features. The patient was treated with oral prednisolone and her symptoms improved dramatically.

To achieve an esthetic restoration, visualized information considering the facial aspect of patient is required. As for the reasons of esthetic failure, it could be explained by lack of communication and information such as horizontal, vertical and esthetic line. Therefore, it is important to deliver that the visualized information to dental technicians or other dentists for the success of esthetic treatment. This case report presents the process of visualizing esthetic information and designing the restoration using a digital diagnostic tool; Digital Smile Design.

Sprayed fire resistive materials are mainly used at steel structures to satisfy fireproof construction standard. However, the regulations on bond strength have been not considered with the exception of structures in the nuclear power plants, although it is an important factor showing material properties. Therefore, this paper suggested guidelines for bond strength of sprayed fire resistive materials used in the substation, by measuring bond strength according to aging of structures and impact loading considering environment of substations. It is judged that the bond strength suggested in this paper is the minimum value because it was measured from specimens widely used.

Functions of metadata, semantic and syntatic schemas, metadata service such as registries, repositories, the optimal metadata retrieval, and several considerations of implementation of digital libraries were the research scopes of this investigation. R&D outcomes of metadata subjects in the domestic community for the past 10 years were searched and analyzed. It illustrated the major results, distinctive trends as well as some insufficient aspects to satisfy the researchers and operators of metadata system development.

According to the Public Records Act, the actual conditions of Government Agencies will be assessed by the concept of 'Assessment' not by 'Instruction and Checking'. In this Study, before adopting a new National Assessment of complying with Records Management, on the basis of the analysis of current 'Instruction and Checking' and other Countries' system which will be able to the model of our new system, we suggest that a Assessment system which will play a role to fulfill and spread the Public Records Act and Records management Standard in this nation's public sector.

원자력발전소에서 비상디젤발전기는 노심의 안전성을 지키는 매우 중요한 역할을 담당하고 있다. 이를 위해 디젤발전기는 신뢰성능 높게 유지하도록 규제요건이 마련되어 있다. 디젤발전기의 엔진 상태를 주기적으로 감시하고 평가하기 위해서는 엔진 상태 신호 분석 기술이 필요하다. 엔진 상태 신호 분석에는 연소분석과 진동 및 초음파 측정 및 분석기술이 중요한 비중을 차지한다. 연소 분석은 디젤 엔진의 개별 실린더에 대한 연소 성능에 대한 정보를 제공한다. 진동 및 초음파 분석은 이벤트 타이밍과 기계적 상태에 대한 정보를 알려준다. 이들 신호는 정상적인 부하로 운전하는 디젤엔진의 가동에 영향을 미치지 않고 수집할 수 있다. 엔진 상태 신호 분석을 이용하는 주요 동기는 전통적으로 장비 제작자의 권고에 따라 수행되는 분해-검사 유지 보수 프로그램을 일부 대체하고 예측정비를 통해 신뢰도를 유지하기 위함이다. 상태 진단정비는 엔진 상태 신호분석을 주로 이용하여 엔진의 신뢰도와 이용률을 증가시킬 수 있다. 본 논문에서는 국내외서 경험한 엔진상태신호 측정 및 분석 사례를 기술하였다.
