The Shingen Embankment built about 450 years ago by Takeda Shingen on the Fuji River and the Kamanashi River was designed to control flood flows in the Midai River (tributary) and the Kamanashi River by means of a series of flood control structures including Ishitsumidashi (stone masonry groins), Shougi-gashira (Japanese chess piece-shaped flow splitters), Hokkiri (dug channel), Juroku-ishi (sixteen large rocks used as energy dissipation works), Takaiwa (natural rock wall) and Kasumi-tei (discontinuous levees). The functions of these flood control structures have been subject to various interpretations, and some of those structures and their functions, such as the functions of a number of Shougi-gashira flow splitters and details on Juroku-ishi, which can only be guessed at today, are mysterious in many ways. This paper introduces an attempt at verifying the flow control technology made possible with these flood control structures by using a table-top hydraulic model developed with the aim of explaining the hydraulic phenomena involved.

High Cr(VI) contaminants have often been detected in groundwater and soils around chromium slag dumping site in Tokyo. The actual status of Cr(VI) seepage in Ojima-Komatsugawa Park was surveyed from January to December 2016, followed with examination of its causes. Firstly, quite heavily concentrated Cr(VI) was detected in seepage water from permeable pipe at the Wansaka Field in the Park. The 50 mm of total rainfall was found to be the trigger for Cr(VI) to leach and spread to the sidewalk. Secondly, Cr(VI) exceeding the standard value concentration flows out into the sewage at the catch basin in Komatsugawa area during rainfall. Leakage at the both points could not be directly related to groundwater level. Results indicated that rainfall causes seepage of Cr(VI), which results in the ongoing pollution in these areas. There had been some attempts to remediate the pollution by applying iron sulfate, however, the investigation revealed significance of further development for fundamental solution.

The Tanaka, Sugo, Inadoi retarding basins which are located along the Tone River have an important role on flood control in the lower Tone river. The lower Tone River has some flood control problems such as flood discharge capacity of the river. In this paper, we developed the unsteady two-dimensional analysis of flood flows using the time series data of observed water surface profiles in the Tone River including the three retarding basins. The calculation model provides a good explanation for flood storage volume in the three retarding basins of 2001 and 2007 floods. Some remarks are given to calculate correct hydrographs of flood storage volume in retarding basins.

In obtaining skipjack having so little body oil as to be suitable for making good “Katsuobushi” thereof, we cannot still to-day but rely on the natural coming of such material. If we had, therefore, any proper means of removing excessive oil from the fish, we would be able to remove also the limitation arising from the seasonal overgrowth of skipjack oil. Carrying out a few experiments on a small scale, the author has ascertained that very satisfactory results can be achieved by applying an alternating current to the material interposed intimately between the electrodes kept in running water. The results are summarized as follows. 1. The higher the voltage, the less oil remains in the meat after the treatment by an electric device shown schematically in Fig. 2. 2. Ampere of the electric current is not of consequence for the effective removal of the body oil. The best range of available voltage is 170-200 V., while too high voltages cause the meat to crack. 3. Continuous refreshment of water surrounding the meat as shown in Fig. 2 is essential to avoiding large and fruitless consumption of electric energy.

山王海農業水利事業で建設を進めていた葛丸ダムは, 平成2年度に完成したことから, 使用開始後のダムの安全管理および施設の維持管理に問題が発生しないよう, 平成3年2月から本貯水に先立ち試験湛水を行った。試験湛水中の観測は, 漏水量・間隙水圧・堤体および基礎の変形・土圧・浸透圧と浸透流量・監査廊の挙動・地震計の挙動の項目を実施しており, これら各項目について貯水位との相関性を明らかにし, 貯水に伴うダム堤体挙動の確認を行った結果を取りまとめたものである。上記の観測結果は, 試験前の推定値よりも極めて少なく, 葛丸ダムは安全な状態であることが確認できた。

Many patients present with extremely serious problems such as headache, photophobia, acoustic hyperresponsiveness, severe pain, menstrual disorders, various sleep disorders, and POTS after human papillomavirus vaccination (HPV vaccine). In addition, patients exhibit various neurological symptoms such as movement disorders, walking disturbance, involuntary movement, abnormal sensation, memory disturbance, and so on. However, these symptoms are variable and have been considered to be symptoms of hysteria (somatoform disorder, somatic symptoms). Immunosuppressive treatments were not administered because many cases were considered to be of neurological origin. In such cases, the disease condition is objectively evaluated to diagnose and treat patients with neurological symptoms. In conclusion, the wide–ranging symptoms of the central nervous system include those caused by disseminated autoimmune encephalitis and also symptoms of the peripheral small fibers. Thus, according to the obtained findings, the neurological symptoms caused by HPV vaccination are related to immunological diseases, and not psychogenic diseases. In addition, the cause of misdiagnosis has also been described.
