Circulation of scientific information improves internationally today, and English which is "universal language" takes the leading part for scientific communication. On the other hand, non-English articles are still "gray literatures" due to language barriers though physical circulation improves as well as English articles. In the International Nuclear Information System (INIS) database operated by the International Atomic Energy Agency (IAEA), bibliographic information such as title and abstract etc. is written in English. This feature of the INIS database contributes to international circulation of scientific information of the nuclear field. However, titles of journals written by non-English language were described by transliterated Roman alphabet, non-native users cannot understand natures and subjects of journals written by non-English language. Non-native users cannot understand the nature of the journal with this journal title description, and then they fail to get the useful article. This language barrier should be broken through as soon as possible for circulation improvement of journals written by non-English language. So we develop a special journal titles translation list of journals written in Japanese for the INIS database, as attempt to improve circulation of articles in journals written by non-English language. We will release this list on the INIS database for circulation improvement of journals written by non-English language, and we will implement the list into the database for user's convenience in the future.

Horonobe Underground Research Center, located in northern Hokkaido, Japan, has been excavating shafts of an underground research facility to establish general techniques for the assessment of deep geological environment. In this site, the groundwater seepage from the shafts and leachate from the waste rock storage site contain high concentrations of total nitrogen. Ammonium-nitrogen (NH
-N), the major nitrogen species in the seepage and leachate, has been removed by a nearby treatment facility. However, NH-N is easily oxidized to nitrite-nitrogen (NO
-N) and nitrate-nitrogen (NO
-N) by nitrification in the excavated rock storage site, which makes the removal process employed on site less effective. Therefore, column experiments that simulated the infiltration of rainwater through the storage site were carried out to understand the phenomena and the factors affecting the leaching behavior of nitrogen species and nitrification, and to propose countermeasures for preventing nitrification. The results showed that the nitrification was inhibited when the rock layer was almost saturated, and that this process was temperature dependent. These indicate that nitrification can be mitigated by controlling hydrological conditions like water saturation.
