Wernicke's encephalopathy is characterized by the triad of ocular symptoms, ataxia, and mental confusion and neuropsychiatric condition generally caused by acute thiamine deficiency. Although it is common in the severe alcoholics, several other causes also have been identified, such as total parenteral nutrition (TPN) use, hyperemesis gravidarum, anorexia nervosa, hemodialysis, uremia, and acquired immunodeficiency syndrome(AIDS). Chemotherapy in patient with malignanacy and long term total parenteral nutrition following bone marrow transplantation are related with Wernicke's encephalopathy. A 48-year-old woman had been treated with Daunorubicin and Cytarabine for remission induction chemotherapy of acute myeloblastic leukemia and intravenous hyperalimentation due to persistent hematochezia and ileus caused by infiltration of leukemic cell in terminal ileum. She suddenly complained of diplopia, tremor, and mental confusion at 32th day after chemotherapy and generalized tonic-clonic seizure at 34th day after chemotherapy. The diagnosis of Wernicke's encephalopathy was made with clinical presentations and brain MRI. Brain MR T2-weighted & Flair image revealed a high signal intensity lesions bilaterally at the medial thalamus and peri-acueductal grey matter of the midbrain. The patient was successfully treated with vitamin B1. We presented a case of acute Wernicke's encephalopathy developed after remission induction chemotherapy followed by intravenous hyperalirnentation in a patient with acute myeloblastic leukemia.

Neonatal lupus is a rare syndrome occurring In neonates with tranplacentally acquired maternal autoantibodies, In particular anti-SSA/Ro-SSB/Ra antibodies. Manifestations include congenital heart block, cutaneous lesions, thrombocytopenia, neutropenia, pulmonary or neurological disease and hepatitis. The non-cardiac manifestations resolve by 6 months of age, congenital heart block is irreversible. We experienced a case of neonatal lupus with congenital complete heart block in a newborn of asyptomatic mother with anti-SSA/Ro-SSB/Ra antibodies.

A compliant mechanism is a mechanism that produces its motion by the flexibility of some or all of its members when the input forces are applied. Whereas the topology optimization based on homogenization and SIMP parameterization has been successfully applied for compliant mechanism design, an ESO approach has not been considered yet for the optimization of these types of systems. This work presents a modified version of the evolutionary structural optimization (ESO) Procedure for its application in topology optimization of compliant mechanisms, It will be shown that an additive version of this method must be adopted in order to achieve the optimum design, since the traditional ESO method's element removal technique is not efficient in this case. The methodology is based on a mutual energy concept for formulation of flexibility and the ESO method. A multi-objective optimization problem is formulated as an application of compliant mechanism design. The procedure has tested in several numerical applications and benchmark examples to illustrate and validate the approach.

This paper describes a design of trasducer for non-invasively detecting pressure radial pulse wave in aterial system and a recording system that for the striding the aterial pulse diagnosis of korean traditional medicine. The mechanism of transducer is composed of sensing mechanism, pressure sensor, conditioning amplifier. The variation of radial pulse pressure in the sensing mechanism is converted to the electric signal by piezo-resistive pressure sensor and it converted to the digital signal after preprocessing via A/D converter. The converted signals inputed to the computer as data files and then it display to the monitor for waveform watching and this datas can be used as the aterial pulse diagnosis data. This system effectively detect non-differential radial pulse wave and we conside that if analizing the recorded radial pulse wave, compared each other, it can be helpful in quantify radial pulse wave diagnosis of the Korean traditionl medicine.

Injection molding is the most widely used process for the industrial forming of plastic articles. During an injection molding process of composites, the fiber-matrix separation and fiber orientation are caused by the flow of molten polymer/fiber mixture. As a result, the product tends to be nonhomogeneous and anisotropic. Hence, it is very important to clarify the relations between separation. orientation and injection molding conditions. So far, there is no research on the measurement of fiber orientation using image processing. In this study, the effects of fiber content ratio and molding condition on the fiber orientation-angle distributions are studied experimentally. Using the image processing method, the fiber orientation distribution of welding parts in injection-molded products is assessed. And the effects of fiber content and injection mold shapes on the fiber orientation in case of fiber reinforced polymeric composites are studied experimentally.

In this paper, The retrieval methods consists of histogram intersection and color pairs. The preprocessor for image retrieval manage linearly the existing HSI(hue, saturation, intensity). Hue and Intensity histogram thresholding for each color attribute are performed to split the chromatic regions and the achromatic regions. Region growing is used to solve oversegmentation problem. Each image is divided into a smaller number of cells of 32 × 32 pixels. Color pairs are used to representthe query during retrieval. The average Recall/Precision of histogram intersection is 0.66/0.69. The average Recall/Precision of color paris is 0.47/0.60. The average Recall/Precision of proposed method is 0.76/0.79. The proposed method increases the retrieval effectiveness. The results demonstrate that the proposed method has led to substantial improvement in the performance of the system.

Railroad station has changed the urban structure spatially, kept its role as a local point and been used as a means of urban development as the urban central axis. However, as the urban central axis has been shifted due to the external expansion of city and the spatial structure of city has been changed, it has caused a lot of urban problems such as housing difficulty and traffic jam at existing downtown. Therefore the transfer of Gwangju station is urgently required to settle many evils such as traffic jam, frequent traffic accidents, separation of life circle, noise and vibration due to the disconnection of traffic axis through the downtown. Accordingly, it will be desirable that Gwangju station will be transferred in consideration of conforming to balanced urban development of Gwangju city, urban spatial structure and residents convenience.

Using low pressure chemical vapor deposition (LPCVD), TiN thin films as field emitter array were fabricated. In this Work, a method was transfered to a substrate and the wet-etching of the silicon substrate instead of fabricated method of mold shape was using in generally but we have fabricated gated field emitter tips as using mold shape of the new method that using a side wall space structure. Following sequences such as LPCVD method of a gate electrod and gate oxide on a silicon substrate and defesited BPSG thin film as a high temperature was flowed by the mold shape of a sharpen, the TiN as a materials of emitter tips was deposited after was bounded by anodic bonding and the wet-etching of the silicon substrate by using KOII solution, the last have fabricated a gated field emitter arrays of a sharpen. These emitters were estmated by scanning electron microscopy and X-ray diffraction.

Chronic recurrent dislocation(CRD) of the jaw has various etilogical causes, including trauma, congenital or acquired neurological illness, ingestion of certain medicines, incorrdination of the neuromuscular astivity of the chewing muscles, articular anatomical alteration, etc. Various surgical methods have been advocated for the treatment of the CRD. They may be divided into two groups: procedures designed to limit translation of the condyle and procedures eliminating obstacles in the condylar path. Hypomobility of mandible can be developed after BSSRO and it is probably caused by scar contracture, atrophy, and myofibrosis. Many authors, therefore, emphasized the importance of physical therapy especially after BSSRO to prevent the complication. Based on that idea, we designed more conservative surgical method to limit mandibular openning compared the methods that previously introduced and tried to treat the CRD. This new method consists of extensive subperiosteal dissection of masseter and the temporalis muscle under local anesthesia and use of intermaxillary elastics for some periods.
