In this study, PD(partial discharge) signals which occur at stator coil of traction Motor are acquired these data are used for classifying the PD sources. NN(neural network) has recently applied to classify the PD pattern. The PD data are used for the learning process to classify PD sources. The PD data come from normal specimen and defective specimens such as internal void discharges, slot discharges and surface discharges. PD distribution parameters are calculated from a set of the data, which is used to realize diagnostic algorithm. NN which applies distribution parameters is useful to classify the PD patterns of defective sources generating in stator coil of traction motor.

이중 포트 메모리의 사용이 증가함에 따라, 이중 포트 메모리의 테스트와 진단이 중요하게 여겨지고 있다. 본 논문에서는 메모리의 테스트 과정에서 고장이 검출되었을 때, 발생한 고장의 종류를 세부적으로 분류할 수 있는 새로운 진단 알고리듬을 제안한다. 본 알고리듬에서는 진단을 위한 패턴뿐만 아니라 테스트 결과를 통하여 얻을 수 있는 정보를 이용하여 진단 과정의 효율성을 증대하였으며, 이중 포트 메모리에서 발생할 수 있는 다양한 고장에 대하여 진단이 가능하다.

Human Ly-6/uPAR molecules are a superfamily composed of two subfamilies; one is the membrane bound proteins with a GPI-anchor and the other are secreted proteins without the GPI-anchor. Ly-6/uPAR molecules have remarkable amino acid homology through a distinctive 8-10 cysteine-rich domain that is associated predominantly with O-linked glycans. These molecules are encoded by multiple tightly linked genes located on Chr. 8q23, and have a conserved genomic organization. Ly-6/uPAR molecules have an interesting expression pattern during hematopoiesis and on specific tumors indicating that Ly-6/uPAR molecules are associated with development of the immune system and carcinogenesis. Thus, Ly-6/uPAR molecules are useful antigens for diagnostic and therapeutic targets. This review summarizes our understanding of human Ly-6/uPAR molecules with regard to molecular structure as well as what is known about their function in normal and malignant tissues and suggest Ly-6/uPAR molecules as target antigens for cancer immunotherapy.

Synovial sarcoma is commonly found in the extremities of mesenchymal origin, but rare in the head and neck area. Histopathology is diagnostic and it shows a biphasic pattern with two neoplastic elements; spindle cell, sarcoma like stroma and gland like clefts lined by epitheloid cells. Synovial sarcoma is high-grade neoplasm that expresses epithelial as well as supporting features. This paper presents a case of synovial sarcoma of hypopharynx on 25 years old male. He was treated by surgical excision and postoperative chemoradiotherapy. There were no evidences of local recurrence & distant metastasis for 19 months postoperatively.

A numerical technique is employed to simulate the flow patterns in the human carotid artery and a phantom of the carotid artery made of acrylic material is used to observe the flow phenomena in the carotid artery. For numerical analysis the idealized geometric shape of the carotid artery is constructed to portray the phantom. Steady momentum equation is solved by the finite element method and the numerical results are compared with the results of MRA and color Doppler images.

Objective : The purpose of this paper is to report the effect of Sosiho-tang gagambang on Obesity based on Shanghanlun provisions Methods : According to a disease pattern identification diagnostic system based on Shanghanlun provisions, the patient was diagnosed as Yangmyung-byung, and treated for 90 days with Soshiho-tang gagambang that Scutellariae Radix was substituted with Salviae Miltiorrhizae Radix. The result of treatment was evaluated by Body Mass Index(BMI). Results : After taking Soshiho-tang gagambang for 90 days, the patient's BMI was decreased, and the patient is cured of Obesity. Conclusions : This study suggests that the treatment based on Shanghanlun provision has efficacy on Obesity. In addition, further studies are necessary in order to discover the roles of flavor of Shanghanlun herbal decoctions, and ensure the safety of it.

Objective : The purpose of this study was to report the improvements of patients with globus pharyngeus treated with herbal medication from Shanghanlun. Methods : Each patient was diagnosed with Greater-yang disease 29th provision of Shanghanlun, and Gamchogungang-tang was used to treat. The result was evaluated by Glasgow-Edinburgh Throat Scale(GETS). Results : The GETS score decreased from 23 to 4 after 40 days of administration in case 1 and from 31 to 1 after 15 days of administration in case 2. Conclusions : Globus pharyngeus improved in each case. This case report suggests that '急' based on the 29th provision of Shanghanlun, can be a direct psychological cause of globus pharyngeus.

Objective : This case report presents the effect of Hoiyeok-tang on atopic dermatitis. A patient was diagnosed with Lesser Yin disease based on Shanghanlun provisions. Methods : According to the disease pattern identification diagnostic system based on Shanghanlun provisions (DPIDS), we diagnosed the patient with Lesser Yin disease. The patient was treated with Hoiyeok-tang for 87 days. The changes in symptoms were estimated by the SCORAD index. Results : After treatment, the SCORAD Index improved from 57.3 to 33.5. The patient also body weight from 89.1 kg to 76.5 kg. Conclusions : This case study shows the effectiveness of Hoiyeok-tang on atopic Dermatitis according to DPIDS.

Objective : To explore the meaning of Eumyangyeokchahunobok-byung (陰陽易差後勞復病) through two cases and finding the relationship with the DSM-5 sleep-wake disorder. Methods : Following a disease pattern identification diagnostic system based on Shanghanlun provisions (DPIDS), we analyzed cases with chronic fatigue and diplopia caused after sleep disorders. The patients were treated with the Soshiho-tang and Yijoong-tang. Results : The two herbal medicines showed remarkable improvement in the patients. The sleep disorders and the secondary pathologies were rapidly relieved within a month. Conclusions : The patterns of sleep disorders of the two patients were found to be very similar to the circadian rhythm sleep-wake disorders, as described in DSM-5. Although the etymology of the Chinese characters has not been clearly known yet, it was possible to present the original hypotheses on 更and 了due to clinical inference.

The spray characteristics of the rotating fuel injection system were investigated. The special test rig was devised to get the spatial and momentary droplet information. This experimental apparatus consists of a high-speed motor, a shaft, a rotating fuel nozzle and an acrylic case. Spray droplet size and velocity were measured by PDPA(Phase Doppler Particle Analyzer) and instantaneous velocity field was measured by 1'IV (Particle Image Velocimetry) system. At the same time, spray visualization was performed by using ND-YAG laser-based flash photography. From these two different laser diagnostic techniques, we could get spatial and instantaneous spray information fur rotating fuel injection system. The results presented in this paper indicate that spray characteristics such as droplet size, velocity and spray pattern were strongly influenced by rotational speed.
