マダイにおける第一卵割阻止型雌性発生二倍体 (mitotic-G2n) 誘導のための最適条件の検討を行った。染色体の倍数化は高水圧処理法を用いた。高水圧処理の媒精後処理開始時間, 処理水圧, 処理時間の組み合わせにより条件検討を行いそれぞれの試験区でビーカー試験により孵化率, 正常二倍体孵化率, および半数体孵化率を求めた。mitotic-G2nの誘導に最適と考えられる条件は高水圧処理の媒精後処理開始時間45分, 処理水圧700kg/cm2, 処理時間5分であり, この場合の孵化率は35.06%, 正常二倍体孵化率は53.41%, 半数体孵化率は46.59%であった。しかし, 異数体と思われる個体の出現が多く変態期は大量へい死もみられたことから, さらに最適条件の検討を重ねる必要性が示唆された。

火山活動に伴い発生する津波は,地震による断層運動を要因とする津波より発生頻度が低く,その実態はあまり明らかになっていない.また,火山活動に伴い発生した津波の国内外事例を対象に解析的検討が実施されているものの,発生過程は多様であり未解明な部分が多い.そこで本研究では火山活動に伴い発生する津波のうちカルデラ陥没に着目し,水理模型実験によりカルデラ陥没を想定した津波の発生機構を明らかにするとともに,数値計算により既往の検討手法の妥当性を検証した.その結果,水理模型実験によりカルデラ陥没に伴う津波の発生機構が確認できた.また,水理模型実験結果の再現計算により既往の検討手法による初期波形計算手法でカルデラ陥没に伴う津波の発生が表現可能である.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

It is difficult to reuse the construction sludge directly because the water content of it is extremely high. Therefore, it has been disposed as industrial waste in the final disposal site. In order to reduce the construction cost and environmental load, the effective reuse of construction sludge has been an important problem. In order to increase the recycling rate of construction sludge and to solve the above mentioned problem, the authors have already developed a new recycling method for construction sludge by using paper debris and cement. As this method can improve the high water content sludge into high quality ground materials on sites, this method has already been utilized in over 400 construction sites in Japan.On the other hand, the biodegradation of fibrous materials is not made clear as yet. It is considered qualitatively that fibrous materials used in this method is hard to be biodegraded by soil microbes, because fibrous materials still remains in the soil which was improved by this method 10 years ago. However, the degradation by soil microbes is not confirmed quantitatively.Therefore, the biodegradability of fibrous materials was investigated experimentally through a culture test and a soil buried test. As a result, it was found that paper fragments were degraded in the solution of pH7.0, but were not degraded in the solution of pH9.5. Furthermore, it was confirmed through soil buried test that paper fragments buried in the normal mud were degraded significantly, but those buried in Fiber-Cement-Stabilized soils were not degraded and fibrous materials remained. Therefore, it was concluded that the fibrous materials in Fiber-Cement-Stabilized soil are not degraded by soil microbes when pH of Fiber-Cement-Stabilized soil is over 9.5, and they remains in the modified soils for a long time.
