Mahalanobis Taguchi System (MTS) is a pattern information technology, which has been used in different diagnostic applications to make quantitative decisions by constructing a multivariate measurement scale using data analytic methods without any assumption regarding statistical distribution. The MTS performs Taguchi's fractional factorial design based on the Mahahlanobis Distance (MS) as a performance metric. In this work, MTS is used for analyzing Wisconsin Breast Cancer data which has ten attributes. Ten different tests are conducted for the data to determine if the patient has cancer or not. Also, MTS is used for reducing the number of test to define the relationship between each attribute and diagnosis result. The accuracy of diagnosis is compare with two different previous research.

This paper presents a diagnosis method for the detection and location of open-short switch faults in the three-phase power conditioning system. A method for switch fault diagnosis on the power conditioning system is proposed, based on the concordia transform. The switch fault types and locations on power conditioning system are diagnosed by a method in which analyze the d-q current vector locus and current pattern. The Simulation results confirm the proposed diagnostic method.

Kawasaki disease (KD) causes multisystemic vasculitis but rarely manifests with pulmonary symptoms. As its etiology is still unknown, there are no specific diagnostic tools available, and KD can be diagnosed only by the symptom pattern. The presence of unusual clinical manifestations often leads to delayed diagnosis. Here, we report two cases of KD with an initial presentation of pneumonia. KD should be consideration when there is a prolonged inflammatory reaction and progressive pneumonia unresponsive to antibiotics.

Objective: To compare condylar position and morphology among different vertical skeletal patterns. Methods: Diagnostic cone-beam computed tomography images of 60 adult patients (120 temporomandibular joints) who visited the orthodontic clinic of Hallym University Sacred Heart Hospital were reviewed. The subjects were divided into three equal groups according to the mandibular plane angle: hypodivergent, normodivergent, and hyperdivergent groups. Morphology of the condyle and mandibular fossa and condylar position were compared among the groups. Results: The hypodivergent and hyperdivergent groups showed significant differences in superior joint spaces, antero-posterior condyle width, medio-lateral condyle width, condyle head angle, and condylar shapes. Conclusions: Condylar position and morphology vary according to vertical facial morphology. This relationship should be considered for predicting and establishing a proper treatment plan for temporomandibular diseases during orthodontic treatment.

A 6-year-old female Maltese dog (body weight 2.0 kg) was referred to the Veterinary Teaching Hospital, Kangwon National University with primary complaints including exercise intolerance and heart murmur. Based on clinical and diagnostic findings including grade V/VI left basal continuous murmur, bounding femoral pulsation, left ventricular enlargement pattern in electrocardiogram, cardiomegaly with aortic bulging on the thoracic radiography, and shunt flow between aorta and pulmonary artery on the echocardiography, the dog was diagnosed as the left-to-right patent ductus arteriosus. The patent ductus arteriosus was successfully treated by lodging a single embolization coil with transjugular approach.

A one-year-old, 3.25 kg intact male Chinchilla cat presented with acute right hind limb paralysis. Diagnostic imaging studies found cardiomegaly with interstitial lung pattern, abnormal mitral valve leaflets without maximum opening at the end of the ventricular diastole and during atrial systole and severe mitral inflow obstruction. Based on these findings and its young age, the case was diagnosed as congenital mitral valve stenosis. Treatment was directed to stabilize clinical conditions related to heart failure, to prevent further formation of thrombus and to relieve pain associated with thromboembolism. After one month of therapy, hind limb motor function was fully recovered.

Two species of the chloroperlid stonefly, Alloperla medlata and Sweltsa illiesi, are reported for the first time in Korea. Alloperla mediata can be distinguished by the smaller epiproct and the presence of a median sclerite under epiproct in male, and by the modified subgenital plate in female. Sweltsa illiesi can be distinguished by the presence of a pair of ridges on tergum 9 in male and upward V-shaped pattern on the center of head in adults. The line drawings of diagnostic characters and taxonomic remarks of the two species are provided with keys and comparative characters for adults of Korean Chloroperlidae.

Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma, which occurs predominantly in adolescents and young adults. The cytological characteristics of this condition have been described only rarely in the literature. Here, we report a case of alveolar soft part sarcoma. A 28-year-old man presented with a mass in his right buttock, which had persisted for three years. The mass was subjected to a fine needle aspiration cytology (FNAC). The smears were cellular. The observed tumor cells were round or polygonal, and exhibited vesicular nuclei with prominent nucleoli and finely granular cytoplasm. Naked nuclei were frequently detected. Tumor cells were arranged singularly, but occasionally in a pseudoalveolar pattern.

An experimentation on the on-line fault detection and diagnosis(FDD) system has been performed with HVAC system in he experimental building constructed inside the large scale environmental chamber. Personal computer with a home-made FDD program by pattern recognition method utilizing artificial neural network was connected on-line via Ether-net TCP/IP to the supervisory control server for HVAC system. The FDD program monitored the HVAC system by 1 minuted interval. The results showed that he FDD program detected the sudden or abrupt faults such s those in fans, sensors and heater, etc.

Yeast strains were isolated from healthy women(36 isolates), infertile women(15 isolates) and women suffering from local morbidity(82 isolates). On the basis of 37 different physiological and morphological characteristics, the isolated 133 yeast strains were assigned to 10 species belonging to 5 genera. Four pathogenic species were identified. They were Candida albicans, Candida parapsilosis, Candida tropicalis and Trichosporon beigelii. Candida albicans was the dominant species, whereas Saccharomyces cerevisiae prevailed among the saprophytic species. The percentage occurrence as well as the pattern of yeast species differed in the diagnostic groups. It was higher in the women suffering from local morbidity than in the healthy and infertile women. Moreover, a wider spectrum of species was isolated from this group. Women with intrauterine contraceptive devices showed the highest percentage of yeast occurrence which reached 50% of those tested. Five different antifungal agents were tested fro their effects on the growth of the isolated yeast species in vitro. Nystatin was the most effective against the isolated yeast species, followed by pyrithion zink and ciclopiroxolamine, whereas micronazole and clotrimazole, showed a lesser effect.
