  • The Mahalanobis-Taguchi System is a diagnosis and predictive method for analyzing patterns in multivariate cases. The goal of this study is diagnosis of the spondylolisthesis from biomedical data that is derived from the shape and orientation of the pelvis and lumbar spine. The data set has six attributes including pelvic incidence, pelvic tilt, lumbar lordosis angle, sacral slope, pelvic radius and grade of spondylolisthesis and two class including normal and abnormal. From University of California at Irvine machine learning repository, 100 normal and 150 spondylolisthesis patient's data were used for this study. Mahalanobis Taguchi System (MTS) application process and the diagnosis results were described in this paper.

  • In this paper, an intelligent fault location and diagnosis system is proposed. The proposed system identifies the fault location in two-step procedure. The first step identifies candidates of fault location using an fault distance calculation using an iterative method. The second step is diagnosis the actual fault location in the candidates by comparing the current waveform patterns with the expected operation of the protective devices and considering the interrupted load after the operation protective device. The simulations results in the case study demonstrates a good performance of the proposed fault location and diagnosis system.

  • Method of diagnosis in oriental medicine, the unbalance of the physiological function of the five viscers and six bowels of the human body is determined from time immemorial with the condition of blood circulation which is performed through blood vessels by the vitality of the heart. In oriental medicine, treatment is largely attempted by adjusting this unbalance. The analysis of pulse wave, which mainly measures the changes in blood flows, is to evaluate the shapes of a pulse wave rather than the quantitative changes like rates and strength of the pulse. This paper presents the development of Hardware System and Pulse Diagnosis Algorithm for automatic diagnosis of the pulse wave. This system makes the precise diagnosis and the objective recording possible.

  • This study aims to develop strategic diagnosis framework of performance by identifying and analysing the dynamics of the technology commercialization ecosystem in innovative region. To achieve the purpose of this study, the systems thinking approach is used. The systems thinking approach connects feedback structure and behavior more explicitly to diagnosis vicious feedback loop in the regional technology commercialization ecosystem. In terms of an ecological point of view, it will be possible to explore dominant feedback structure and find leverages to overcome the limitations of regional technology commercialization performance. The diagnosis of reenforcing and balancing feedback structure is based on the statistical analysis of the survey data which has been collected in a cluster random sampling method, targeting on the 200 firm located in the Pangyo and Daeduk region. The results from this research showed that the regional technology commercialization ecosystem was immature and faced limit to the growth. An important finding of this study was that regional technology commercialization ecosystem need to activation of startups and reinforcement of virtuous feedback structures of technology commercialization market systems.

  • The mediastinoscopy was a well known useful diagnostic tool for detection of mediastinal lymph nodes invasion by bronchogenic carcinoma, and also useful means for histologic diagnosis of metastatic carcinoma and certain mediastinal tumors. 31 cases of mediastinoscopies were reviewed which were experienced at Kyung Hee University Hospital from July, 1979 to June, 1985. We experienced 20 cervical mediastinoscopies, 10 left anterior mediastinotomy, and 1 both procedures. Of the 31 cases, 22 cases were used for preoperative staging of bronchogenic carcinoma, 7 cases for mediastinal tumor diagnosis, and 2 cases for histologic diagnosis of metastatic carcinoma. In 22 mediastinoscopies which were used for preoperative staging, 10 cases were revealed positive mediastinal nodes, and could avoid meaningless thoracotomy. All 12 mediastinoscopy negative patients were received thoracotomy, and 10 of them were resectable. The resectability in bronchogenic carcinoma was 83%, on the contrary, the other series at premediastinoscopic era revealed only 65% resectability. Other mediastinal lesions such as tuberculous granuloma [4], sarcoidosis [2], malignant thymoma [1], and metastatic carcinoma [2] were also diagnosed successfully. Mediastinoscopy is very useful tool for determination of treating method of bronchogenic carcinoma, and for diagnosis of certain mediastinal tumors which, otherwise, need a thoracotomy for confirmatory diagnosis.

  • For having good therapeutic value, putting the ideal of diagnosis and treatment based on overall analysis of symptoms and signs[辨證施治] into practice is very important, so the Eastern Medicine's peculiar diagnosis without interference by the western medical diagnosis is very important. The peculiar method of Eastern Medicine's diagnosis is four methods of diagnosis(四診法), a joint term for inspection, auscultation and olfaction, interrogation, pulse feeling and palpation. In the process of interrogation[問診], from analyzing the perspiration phase, doctor can get various physical information. Especially perspiration from particular region can be a clue for founding focus or cause of disease. This thesis divide the phase of perspiration into eight bodily region, perspiration from all body, head, face, back, chest and armpit, stomach, pubic region and lower part, hands and feet, and inquire the possible causes and principles of these perspirations. In conclusion, the regional perspiration can be a clue point out the origin of fever and condition of Gi(氣) flow. Perspiration from head, back, chest and armpit, hands and feet means that certain fever cannot extend to the outside of body, and at the same time, means the Gi(氣) flow of outside is being intercepted. So the perspirations from that region become an object of medical treatment.

  • Since ${\ll}$Hwangjenaegyeong(黃帝內經)${\gg}$ and ${\ll}$Nangyeong(難經)${\gg}$, there has been various methods in pulse diagnosis. The Chon-gu(寸口)/Inyeong(人迎) Pulse Comparison Diagnosis which is dealt with in many chapters of the ${\ll}$Hwangjenaegyeong${\gg}$, has not been as widely applied as the Chon-gu Pulse Diagnosis due to several limitations. In this paper, we will review these limitations and suggest an alternative method. In the Chon-gu/Inyeong Pulse Comparison Diagnosis, we compare the Chon-gu Pulse and the Inyeong Pulse to see which is larger than the other by times, and diagnose illness of the 12 Meridian Pulse. It is fairly clear which is larger than the other, but to determine by how much accurately is quite difficult to say. However if we combine the Five Viscera Pulse in application, it becomes far more easier to determine which viscera and bowel is ill. First, study the pulse of the Chon-gu and In-yeong, then determine the Viscera Pulse. Next, determine the larger pulse between the Chon-gu and In-yeong pulse.

  • For the purpose of integrating nursing diagnosis into the nursing curriculum, a descriptive survey research was done using the inductive method with questionnaires and a literature review. Research subjects included nurse educators, textbooks of adult nursing published in Korea, and the course outline for adult nursing used in one college of nursing. The Results show that there was common agreement on 39 nursing diagnosis which should be in cluded in the adult nursing curriculum, textbooks of adult nursing, and patient care on the medical-surgical units. The two existing nursing diagnosis classification systems(NANDA and Gordon's Human Response Patterns) show different basic frameworks and difficulties were discovered in integration of nursing diagnosis into the curriculum. To develop a conceptual framework for a nursing diagnosis classification system, diagnosis were classified into three categories ; health promotion, high risk problem, and actual problem on the basis of the framework used in adult nursing textbooks and Gordon's 11 Functional Health Patterns. Subconcepts for actual problems were classified as ; activity and rest, nutrition and elimination, perception and coordination, stress and coping. Progress in this study supports further development of a conceptual framework of nursing based on a nursing diagnosis classification system, from which improvement in nursing education and clinical practice can be expected.
