Deformation of an aluminum alloy sheet is affected by its underlying crystallographic texture and has been widely studied by the crystal plasticity finite element method (CPFEM). The numerical material test based on the CPFEM allows us to quantitatively estimate the stress-strain curve and the Lankford value (r-value), which depend on the texture of aluminum alloy sheets. However, in the use of the numerical material test as a means of optimizing the texture to design aluminum alloys, the CPFEM is computationally expensive. We propose a methodology for rapidly estimating the stress -strain curve and r-value of aluminum alloy sheets using deep learning with a neural network. We train the neural network with synthetic texture and stress-strain curves calculated by the numerical material test. To capture the features of synthetic texture from a {111} pole figure image, the neural network incorporates a convolution neural network. Using the trained neural network, we can estimate the uniaxial stress-strain curve and the in-plane anisotropy of the r-value for various textures that contain Cube and S components. The results indicate that the neural network trained with the results of the numerical material test is a promising methodology for rapidly estimating the deformation of aluminum alloy sheets.

In the present study, we investigated the distribution of patients with sudden deafness in Japan using the data obtained by the fourth nationwide epidemiological survey on sudden deafness conducted by the Research Committee of the Ministry of Health Labour and Welfare in 2001. We investigated the distribution of patients by dividing the whole country into 9 districts and 47 prefectures. The annual number of patients with sudden deafness per 100, 000 was from 17 (Shikoku) to 42 (Chugoku) and from 3 (Yamanashi, Nagasaki) to 48 (Osaka), respectively. More patients tend to be reported in densely-populated areas judging from the data concerning the distribution of patients per 100, 000 in each prefecture.

The author is attracted to the reports which record the community health activities. The reason is that he has been taken into the situation described there and felt as if he faced the same situation and experienced just the same things, which makes him enable to develop new ways to think. Such reports are written in a way that reporters describe what they actually experience and observe.The author took up the theme of “case-reporting as methodology”, because I have often met reports which only tell the results of measuring something but fail in conveying what reporters actually experienced. There might be misunderstanding that case-reporting is not allowed to be taken as a scientific way, and in consequence case-reports seldom come out in front of me.While touching on the essentials of natural science in relation to the observation of the natural world, this presentation tried to clarify the role and the purpose of case-reporting in the aspect of method with which one can describe what he or she experiences and observes in the community health activities.
