[en] A report is given on the plans of the Japanese Ministry for International Trade and Industry (MITI) for the extraction of uranium in series (coupling with heat or nuclear power plant) or tidal methods, from sea water. (UA/LH)

[en] In 2016, Ecological Research (ER) celebrated its 30th anniversary. ER’s goal is to be the leading ecological, evolutionary, and biodiversity journal in Asia. This article introduces the development of ER, improvements to its editorial system and their outcomes, and the strategies designed to achieve this goal. ER has already become a leading comprehensive and international publication as shown by statistical evidence and its strong editorial foundation. However, some members of the Ecological Society of Japan (ESJ) retain impressions of an old stereotype about ER. The discrepancy between the current status of the journal and its stereotype may explain why submissions from Japan remain static. A new article category for ER, Biodiversity in Asia, was created to encourage Asian studies. In addition, the Forum category is dedicated to promoting a broad understanding of the ESJ’s various activities. To promote open science, the proportion of open access articles in the journal is increasing. The publication of Data papers has been accelerated to improve the public availability of excellent open data sets. ER symposia and seminars provide good opportunities for members to participate. ER financially supports the invitation of scientists internationally to facilitate research exchanges with other countries and consequently promotes the internationalization of the ESJ. The ESJ is open to the world’s ecologists, and your participation in developing ER is welcome.
[en] The KIER's Korean historical earthquake catalog was revised for MMI≥VI events recorded from the years 27 A.D. to 1904. The magnitude of each event was directly determined from the criteria suggested by Seo. The criteria incorporated the damage phenomena of the Japanese historical earthquake catalog, recent seismological studies, and the results of tests performed on ancient structures in Korea. Thus, the uncertainty of the magnitudes of the Korean historical earthquakes can be reduced. Also, the Gutenberg-Richter parameter values were estimated based on the revised catalog of this study. It was determined that the magnitudes of a maximum inland and minimum offshore event were approximately 6.3 and 6.5, respectively. The Gutenberg-Richter parameter pairs of the historical earthquake catalog were estimated to be a=5.32±0.21, b=0.95±0.19, which were somewhat lower than those obtained from recent complete instrumental earthquakes. No apparent change in the Gutenberg-Richter parameter is observed for the 16th-17th centuries of the seismically active period
