Segmental zoster paresis (SZP) is a clinically rare complication of herpes zoster. But it has not been reported that acute cerebral motor cortical infarction coincidentally occurred in SZP. A 86-year-old woman was admitted due to pain, tingling sensation, and weakness of left arm. She had an acute onset of pain and tingling sensation in left arm at first day, shoulder weakness at second day, and multifocal vesicles at fourth day. Deep tendon reflexes of left arm were decreased than right. Electromyography showed an axonal polyneuropathy at superior trunk level of left brachial plexus. Median and ulnar sensory evoked potential tests were normal. Brain MRI showed a high signal in right primary motor cortex on diffusion weighted image. We report a case of acute cerebral motor cortical infarction coincidentally occurred in SZP.

Our Goal of modified segmental osteotomy on maxilla accompanied by mandibular anterior subapical osteotomy was to get the best results from patients of bi-alveolar or bi-maxillary protrusion. In this study, cephalometric and photo (en face, profile) analysis have been compared to define the soft tissue change after surgery. Lip protrusion was efficiently reduced and nasolabial angle was much obtused. Although nose was a little widened, it was quite acceptable. Blood circulation on osteotomized segment was well maintained. This relatively simple methods could be successfully applied to many patients.

Two patients with chronic Budd-Chiari syndrome resulting from segmental obstruction of the inferior vena cava underwent operation. There were 1 man and 1 woman. The obstructed segment was directly visualized by a transthoracic, transdiaphragmatic, retroperitoneal approach. In these two cases, severe segmental obstruction of the inferior vena cava was observed just above the right hepatic vein. These patients underwent successful retrohepatic cavoatrial bypass with a polytetrafloroethylene [PTFE] graft [ 16mm plain and 16mm ringed graft ]. There were no operative mortality and postoperative complication. These patients have been followed up for 6months and 36months without evidence of re-obstruction. When there is a severe stricture of the IVC with hepatic veins draining freely into the obstructed segment of the IVC, a dorsal cavoatrial bypass with a PTFE graft, preferably ringed, is the method of choice.

The distribution of renal artery of fifty Korean native cattles (100 kidneys) was observed. Vinylite solution was injected into renal artery of ninety specimens for cast preparation. The angiography was prepared in 10 specimens by injecting thirty percent of barium sulfate solution into renal arteries, and then radiographed on a soft X-ray apparatus (Shimadzu Waltes 60). 1. A. renalis arose from the each side of abdominal aorta in the Korean native cattles. 2. The renal arteries were bifurcated into Ramus cranialis and caudalis (91%), and Ramus cranialis, medius and caudalis(9%) which were ramified 1-4 segmental arteries, respectively. 3. The segmental arteries were originated from R. cranialis and R. caudalis (87%), R. medius (9%) and A. renalis (4%). 4. The kidney were divided separately into 5-7 arterial segments by running of the segmental artery into the parenchyma. Among them six segments were mostly frequent(53%). 5. The Arcus arteriosus renalis was observed at 44% of the left kidney and 14% of the right kidney.

Segmental amputation of the digits and hand has been described as a contraindication for replantation because of poor results. We report the results of replantation for a patient who experienced multi-segment amputation of the hand. A 39-year-old man presented six hours after an accident, while using a straw cutter, that caused a multi-segment amputation of the entire palm and digits. The replantation surgery took 18 hours. We observed the patient gain satisfactory function of the hand. For replantation of a multi-segment amputation, connecting as many blood vessels as possible without tension is most important.

The newly proposed Precast Segmental Mettled (PSM), which makes use of precast elements for election, is relatively new, efficient and fast mettled for the construction of prestressed box girder bridges. A precast segment of 25m long pretensioned in the fabrication yard is transported by a special trailer and a launching truss to its final position. The segments are then connected in the site by post-tensioning to make a continuous prestressed concrete box girder bridges. The purpose of this parer is to analyze and evaluate the design of precast prestressed concrete box girder bridges. The detailed analyses including time-dependent behavior of PSM bridges are conducted. The major results and findings, which have been obtained from finite element analysis of PSM bridge, are discussed in this paper and these results will be a good base for the design and analysis of a new precast bridges.

Tendoachilles rupture has recently seen an increase in frequency, accounting for up to 40% of all tendon ruptures. However, an acute segmental rupture of the Achilles tendon is very rare with only one case caused by predisposing factors, such as steroid injection. In this report, we highlight an unusual clinical presentation of a segmental rupture of the Achilles tendon without any underling predisposing factor and without direct trauma. Herein, we discuss its mechanism. Twelve months after surgical repair with open technique, this patient became fully functional again in daily activity.

The application of mechanically stabilized earth wall(MSEW) with segmental front panel has been increasing in highway construction due to its cost-effectiveness. However, some failures during construction have been reported and many field engineers are reluctant to select this method for important structure. One of the main reasons may be that there is no moderate specification for design and construction of MSEW yet. This paper discussed the main results of analysis on a case of block-type segmental retaining wall in highway construction. Based on the results, some recommendations on design and construction method of MSEW are presented.

The behavior of two-level soil-reinforced segmental retaining wall was examined using the finite element analysis. A number of different case was analyzed by varying the reinforcement length and the offset distance between the upper and lower wall. The results indicate that the interaction between the upper and lower walls can be neglected the upper wall is located beyond the distance of the lower wall height. A so found is that for moderate offset distances, the interaction between the two walls generally is limited to the external stability of the wall. Implication of the findings are discussed

Anterior set back segmental surgery has been used for shortening the period of orthodontic treatment in case of bimaxillary or maxillary protrusion. In most cases, it requires pre-operative orthodontic treatment. Through properly performed leveling and tooth aligning, the operative porcedure can be easier and post-operative occlusal stability can be increased. But it takes time for orthodontic treatment. Recently, we have been using anterior segmental surgery before orthodontic treatment and have reliable results from that. Therefore, we have to consider arch shape, curve of Spee, tooth selection to be extracted for obtaining of post-operative occlusal stability without pre-operative orthodontic treatment.
