After the 2011 Great East Japan Earthquake, the Japanese government identified the lack of proficiency in the Japanese language as one characteristic of foreigners that should be considered in disaster prevention *** article seeks to understand how proficiency in a local language affects disaster information gathering behavior by using the results of a questionnaire survey conducted after the 2011 Great East Japan Earthquake. Respondents were categorized based on their Japanese and English language abilities. Their media mode, language preferences, information importance, and information-gathering difficulties also were examined. It was found that foreigners skilled in Japanese demonstrated similar information gathering behavior as Japanese respondents, but foreigners unskilled in Japanese showed little usage of Japanese-language media. This group also encountered difficulties due to a lack of Japanese proficiency, but many members were able to acquire some level of Japanese-language information through Internet-based methods. To address language proficiency in disaster prevention planning, information provision in languages other than Japanese should be increased, and Japanese information should be shared in a way that facilitates translation. Although this survey wassignificant in its scope, the results should be considered within the limitations of the Internet-based response collection and focus only on the less-affected area of Japan.

Differentiation between lethal and non-lethal prostate cancer subtypes has become a very important issue in avoiding excessive treatment in an era when prostate-specific antigen （PSA） screening has reduced the rate of prostate cancer deaths by more than 20%. However, it is difficult to determine the patients who may or may not benefit from immediate treatment interventions at the time of the initial diagnosis. The selection of candidate patients who can postpone immediate treatment and undergo follow-ups with a specific surveillance program, or ＇active surveillance,＇ is a practical way to minimize overtreatment. In this review, the benefits and risks of active surveillance are discussed. Future perspectives, including imaging and new biomarkers for improving the outcomes of active surveillance programs, are also discussed.

The average continental crust possesses intermediate compositions that typify arc magmatism and as a result it is believed to have been created at ancient convergent plate boundaries. One possible mechanism for intermediate continental crust formation is the direct production of andesitic melts in the upper mantle. Sanukitoids, which characterize the Setouchi volcanic belt, SW Japan, include un-usually high-Mg andesites (HMA). They were generated by slab melting and subsequent melt-mantle interactions under unusual tectonic settings such as where warm lithosphere subducts into hot upper mantle. Such conditions would have existed in the Archean. Hydrous HMA magmas are likely to have solidified within the crust to form HMA plutons, which were then remelted to produce differentiated sanukitoids. At present, generation and differentiation of HMA magmas may be taking place in the Izu-Bonin-Mariana arc-trench system (IBM), because (1) HMA magmatism characterizes the initial stages of the IBM evolution and (2) the IBM middle crust exhibits Vp identical to that of the bulk conti-nental crust. Vp estimates for plutonic rocks with HMA compositions support this. However tonalitic composition for middle-crust-forming rocks cannot be ruled out, suggesting an alternative possibility that the continental crust has been created by differentiation of mantle-derived basaltic magmas.

An updated result of European Randomized Screening Trial for Prostate Cancer encourages Asian countries to proceed prostate-specific antigen （PSA） screening for early detection. On the other hand, the issue of overtreatment is emerging as a serious problem. Active surveillance （AS） should be more prevalent than now to avoid overtreatment for patients with favourablerisk prostate cancer （PCa） detected by PSA test.
