Object classification is an important issue in order to bring autonomous vehicle into reality. In this paper, real-time and robust classification based on Real AdaBoost algorithm is researched and ...improved. Various effective features of road objects are computed using LIDAR 3D point clouds. The improved classifier provides an accuracy of over 90 (%) in a range of 50 (m) and classifies objects into car, pedestrian, bicyclist and background. Moreover, processing time of classifying an object consumes only 0.07∗10 −3 (sec) that enables this method to be used for autonomous driving on urban roads.
Abstract To assess the clinical efficacy of oral antibiotic administration for the treatment of lower urinary tract infection (UTI), 102 female patients were given gatifloxacin (200 mg once daily for ...3 days). Five to nine days after treatment, drug safety and clinical efficacy were assessed by evaluation of urinalysis and symptoms. Further, the patients were asked to report by mail whether they had persistent or recurrent symptoms at 4–6 weeks after treatment. The overall clinical cure rate was 93.1% (95/102). Of 94 patients with susceptible pathogens and 8 with resistant pathogens, 89 (94.7%) and 6 (75.0%), respectively, were judged as clinically cured. Four to 6 weeks after treatment, 57 (55.9%) of the 102 patients reported their micturition status by mail, and 6 (10.5%) of them claimed that they had some symptoms. The outcomes of this study suggest that a therapeutic regimen such as administration of fluoroquinolones once daily for 3 days can be recommended for the treatment of uncomplicated cystitis.
Progressive supranuclear palsy (PSP) is one of the most common atypical parkinsonian syndrome characterized by early onset postural instability with falls, vertical supranuclear palsy and symmetrical ...akinesia or rigidity. In Japan, sufficient epidemiological study of PSP has not been performed due to lack of suitable criteria for diagnosis. Recently, clinical criteria for the diagnosis of PSP were proposed by the “Multicentric Clinical Research Studies on the Prevention, Diagnosis and Treatment of Neurological Diseases” group. We validated the specificity and sensitivity of the criteria by using neuropathologically confirmed cases and surveyed the medical care, social service and support system for patients with PSP. Among neuropathologically confirmed cases of multiple system atrophy (n=4), Parkinson's disease (n=8), dementia with Lewy bodies (n=4) and corticobasal degeneration (n=1), no cases satisfied the criteria. Neuropathologically confirmed cases of PSP (n=7) satisfied the criteria without exception, suggesting that the criteria is useful for epidemiologic study or clinical research. Using this criteria, we studied the conditions of the illness, utilization of medical or social services for patients with PSP. Our study showed that the characteristic conditions of patients with PSP was short duration of the illness and a high percentage of deteriorated ADL requiring medical care in hospital. Some clinical problems of the support system which need to be resolved to provide appropriate medical care, health care, and welfare services are discussed.

For this paper, the authors designed three types of SURFACE PIERCING PROPELLERS. Each propeller was constructed with a different type of blade section, one wedge-shaped, one crescent-shaped, and one ...with an improved wedge shape. We checked the propeller's performance around the planned ship speed and also the performance in the astern direction. In order to study the possibility for improvement in lowermedium speed performance, additional model tests were conducted with the submersion ratio, which strongly influences lower-midium performance, changed. Lastly, the authors verified that in an actual vessel, where the submersion ratio can be adjusted by changing the propeller shaft's inclination angle, the performance of the SURFACE PIERCING PROPELLER was improved.
