  • A 4-year-old, American Paint horse gelding with recurrent episodes of exertional rhabdomyolysis was diagnosed with equine polysaccharide storage myopathy (EPSSM). The common clinical signs were muscle weakness, loss of muscle mass, exercise intolerance, difficulty holding up limbs for farrier, sensitivity of grooming, cramping with reluctance to move and the inability to rise. Through histological examination of skeletal muscle specimens, this case was confirmed of EPSSM.

  • We have fabricated pressure sensitive paint films consisting of PtTFPP activators dispersed in fluorinated polymer matrix. This matrix material is unique in its composition and structure. We evaluated the oxygen quenching effects, and thus the pressure sensitivity, of the fabricated films in terms of various processing parameters. Based on the experimental results, we anticipate that a good but new pressure sensitive paint would be presented through further elaboration of the polymer compositions and optimization of the processing conditions.

  • This paper investigates the correlation between surface roughness and gloss of aluminium sheet painted waterborne paint. One customer criterion of automotive quality is the as-painted appearance of the final products. Especially, the current emphasis on control of surface roughness of sanded aluminium sheet has been prompted by the automotive industry's concern with the as-painted appearance. because the influence of such characteristics on paintability, and painted appearance is important in defining outer panel requirements for automobile. This paper is dedicated primarily to the issue of painted appearance and reviews for improvement of roughness. The conclusions are obtained as follows ; 1) Painted aluminium sheet appearance is strongly affected by surface roughness of base-metal and influenced by sand paper and sanding method. 2) The painted appearance of aluminium sheets was determined and related to surface roughness parameters, combination of sand paper.

  • Accelerated and field degradation tests are performed for reliability assessment of an anticorrosive paint for steel structures. Test data were analyzed to obtain the degradation model and the life time distributions of the paint. A power law degradation model and lognormal performance distribution were used to predict the lifetime of the anticorrosive paint and the method of finding an acceleration factor is provided.

  • Recently the building material have been developed with the concept of controlling the indoor environment as well as the concept of emitting contaminants less. So, a lot of products with humidity control characteristics put it on the market. However, objective evaluation to these products doesn't work out. Thus consumers cannot obtain accurate information to these products. Therefore, we selected inorganic paint in the functionality materials and evaluated its humidity control characteristic in this research. We divided by four stages and evaluated this inorganic paint. The 1st and 2nd third experiments were executed on a natural condition and the fourth experiment was executed with humidity had been raised by using the humidifier.

  • In this study, it is quantitatively analyzed for thermal Characteristics of isolation-heat paint which has been supplied to a domestic market through experiments and simulations. In the case of experiment using the container box, it shows 8% decrease on cooling energy consumption in a summer season, but shows increase on heating energy consumption. As a result, the analysis has found increase of energy consumption. As a result of holding simulations with meteorological data of domestic major cities, it shows an increase of energy consumption in domestic condition, and it is hard to expect an energy saving from the isolation-heat paint unless greater air-conditioning load.

  • Hull roughness due to corrosions of outer hull and had applications on outer hull paints was analyzed theoretically. It's value which was gainable practically, was studied, and estimated power penalty formular correspon-ding to that value were reviewed. Local roughness penalty and roughness texture penalty that paint manahers in ship yard can easily were compared and studied by dotting actual ships in the issued curves. Losses and benifits of hull roughness & the specification choise of A/F paint which managers of ship maintenance were much interested in have been calculated through actual ships. The paper is illustrating that how much the specification choise and managing of A/F paint have effects on fuel consumption of ship in program. It is urgently required that recent developed antifouling paints of new A/F generation should be adopted to new ship building by big shipping companies in view of the environmental protection and the economical maintenance of ships.

  • Film cooling effectiveness on a flat plate was measured with pressure sensitive paint. The pressure sensitive paint(PSP) changes the intensity of its emissive light with pressure and the characteristic was used in film cooling effectiveness measurement. The film coolants were air and nitrogen, and by comparing the intensity of PSP coated surface with each coolant, the film cooling effectiveness was calculated. Three blowing ratio of 0.5, 1, and 2 were tested with two mainstream turbulence intensities. Results clearly showed the effect of blowing ratio and mainstream turbulence intensity. As the blowing ratio increases, the film cooling effectiveness was decreased near the film cooling holes. However, the film cooling effectiveness far downstream from the injection hole was higher for higher blowing ratio. As the mainstream turbulence intensity increased, the film cooling effectiveness was decreased at far downstream from the injection hole.

  • In this study, the piezoelectric characteristics of a piezoelectric paint sensor were investigated in relation to the poling time. This piezoelectric paint sensor was composed of PNN-PZT powder and epoxy resin with a 1:1 weight ratio. The dimensions of the paint specimen were $40{\times}10{\times}1mm^3$, and the top and bottom sides were both coated with a silver paste to create electrodes. During the poling treatment, the poling time was controlled to examine the effect of the piezoelectric properties, while the poling temperature was fixed at room temperature and the electric field was set to 4 kV/mm. The piezoelectric properties were measured by comparing the output voltage from the paint sensor to the force signal from an impact hammer when the impact hammer hit the specimen. In conclusion, the optimal poling conditions were found to be an electric field of 4 kV/mm and a poling time of around 30 min at room temperature.
