  • Candidiasis caused by Candida albicans is a localized mucocutaneous disease. It occurs worldwide in various kinds of animals. A 7-year-old male spotted seal weighing 98 kg showed facial skin lesions. The present case was characterized by erythematous, thickened, and alopecic skin lesions in the periocular region and on the commissure of the lower lip. For diagnosis, skin scraping and culture of samples from the facial skin lesions were done. Colonies were cream-colored and glistening after 3 days of culture on Sabouraud dextrose agar. Typical yeast-like cells were observed by microscopic inspection after Gram staining. Recovery was achieved with itraconazole (1 mg/kg SID) for 7 days, repeated three times at 2-week intervals.

  • This paper focuses on the use of the virtual dialog system whose aim is to build more convenient living environments. In order to realize this, the main emphasis of the paper lies on the description of the multimedia signal processing on the basis of the technologies such as speech recognition, speech synthesis, video, or sensor signal processing. For essential modules of the dialog system, we incorporated the real-time speech recognizer based on HM-Net(Hidden Markov Network) as well as speech synthesis into the overall system. In addition, we adopted the real-time motion detector based on the changes of brightness in pixels, as well as the touch sensor that was used to start system. In experimental evaluation, the results showed that the proposed system was relatively easy to use for controlling electric appliances while sitting in a sofa, even though the performance of the system was not better than the simulation results owing to the noisy environments.

  • A giant cell granuloma and a cementifying fibroma occurring in the same lesion of right mandibular body in a 10 year old boy is presented with a 12 month follow up without recurrence or any other complications after operation. The relatively small lesion of cementifying fibroma was well delineated from the larger lesion of central giant cell granuloma, and as their origins are different each other(odontogenic or connective tissue origin), we have considered that both lesions had developed independently. Clinically, the evidencesa of aggressiveness of giant cell granuloma were also found, that is, large size, earlier age of 10, root resorption of lower right 1st annd 2nd molars and cortical perforation. With curettage and electric cauterization, we have treated both lesions satisfactorily.

  • The purpose of this study was to evaluate the changes of interproximal bone density by means of videodensitometer and to examine the clinical applicability of videodentitometer to assess the periodontal disease activity.Twelve interproximal sites, with periodontal pockets deeper than 5mm and vertical loss of bone on standard dental radiograph, were treated by subgingival curettage. The papilla bleeding index, the plaque index, the degree of mobility, the depth of pockets, and the level of attachment were measured. Standardized reproducible radiographs were taken by using the occlusal stent with parallelling film holder. The density of the interdental bone was measured on the radiographs by a videodensitometer at three levels: the most 'superficial' level; the 'deep' level, arbitrarily 1.5mm below: and the 'apical' level, where no bony changes were to be expected. The clinical parameter and the radiographical change were measured at initial, and 1 month, 3 months, and 6 months after treatment.The results were as follows :1. The papilla bleeding index and the degree of mobility decreased significantly until 3 months after subgingival curettage and showed the Same level in the remaining experimental periods. 2. The pocket depth mainly decreased due to the gingival recession until 1 month after treatment, but to the attachment gain after 1 month. 3. The density of the interdental bone did not show a significance increase until 1 month after treatment, but showed a steady increase throughout the 6 months of observation. 4. The close relationships were shown between the decrease in pocket depth and the gain of attachment and the improvement of bone density at 6 months after treatment.

  • The present study has been performed to examine the feasibility of a flame spread model on the design fire scenario for fire risk analysis. Thermo-Gravimetric analysis and sample burning test were conducted to obtain the material properties of a single couch covered with synthetic leather material and a series of FDS calculations applying with the measured material properties were performed for different grid sizes. The overall fire growth characteristics predicted by the fire model were quite different from the results of a real scale fire test and the initial peak value of the HRR and total released energy showed the results within a 30% discrepancy for the computational grids used in the present study. The current model has some limitations in predicting the fire growth characteristics, such as fire growth rate and the time to the maximum HRR. This study shows that the fire model may be applicable to creating the design fire scenario through continuous model improvement and detailed material properties.

  • The objective of this research is to study on the formations of thermal stratification in a room in case of several furniture fires such as trashcan, carpet, sofa, mattress and wardrobe as a fire starter in a residential room by performing the experimental studies. The uniformly distributed fire in case of carpet showed that the ignition and the initial growth period were relatively short while the fully developed period was considerably long. The concentrated fires such as the mattress and wardrobe showed that the ignitions and the initial growth periods were relatively long. When fire spread to only direction, like the case for the trashcan with a regular shape, there was one peak of temperature profile, and for the irregular shaped furniture such as chair, sofa, mattress and wardrobe, there were two or more peaks. The interface heights for the furniture fires were around 1[m] maintaining constant state. However, at the time of the maximum temperature, the interface height was lowered to 0.25[m]-0.75[m] from the floor.

  • Recently the target area for the installation of structures have been changed from shallow water into deep one by reservation and use of the wider coastal region, and development of deep water. Additionally, great emphasis in the improved human life quality has been placed on the necessities for the preservation of the agreeable natural and coastal environments and development waterfront, recreation, and resort in the sea. However, the existing gravity-type breakwater did not appropriately cope with the recent changes of circumstances, but required the enormous construction coat for coping with them. Until now, floating breakwuater, which was adequate for the environment and construction cost, has been actively studied in the other countries including Japan. This floating breakwater has been already constructed in many places and satisfactory in poor subsoil and deep water in Japan. Also it showed the same function as a gravity-type breakwater. But floating breakwater was not control long period waves by reason of constructive characteristic. The aim of this study is to discuss field application of Floating Breakwater with Compound Plate Type(FBCPT) in coastal region by using numerical analyses and hydraulic model test.

  • Reflection coefficients of wave due to the types of a submerged breakwater on the inclined incident wave are numerically computed by using boundary element method. The analysis method is based on the wave pressure function with the continuity in the analytical region including fluid and structures. When compared with the existing results on the inclined incident wave, the results of this study show good agreement. It is found that both maximum and minimum values of the reflection coefficient are appeared frequently, as the width of a submerged breakwater becomes wider, and the reflection coefficient increase, as the wave period is longer. In addition, the effect on the reflection coefficient due to the change of submerged breakwater hight is lager than that due to the change of submerged breakwater width. The results indicate that dissipating characteristics of wave due to the types of a submerged breakwater own high dependability regarding the change of inclined incident waves. Therefore, the results of this study is estimated to be applied as an accurate numerical analysis referring to inclined incident waves in real sea.
