八汐ダム調整池では,熱水変質と大規模岩盤クリープが主な生成要因と考えられる高角度の開口割目を主体とする割目のネットワークが形成され,極めて深部まで連続するミズミチが分布する。止水対策に向けて実施した試験グラウチング等の結果,湛水した状態の調整池底部において地下水位以下で注入を実施した場合,注入圧力に加え,セメント粒子の限界沈降速度より大きな浸透流速を活用して,主な開口割目に対して効果的なグラウチングが図られ,減水効果が確認されている。本論文では,このような注入メカニズムに対して定性的な考察を行ったものである。

In this paper, we first propose a novel interaction model, CEA (Commands Embedded in Actions). It can explain the way how some existing systems reduce the work-load of their user. We next extend the CEA and build ECEA (Extended CEA) model. The ECEA enables robots to achieve more complicated tasks. On this extension, we employ ACS (Action Coding System) which can describe segmented human acts and clarifies the relationship between user's actions and robot's actions in a task. The ACS utilizes the CEA's strong point which enables a user to send a command to a robot by his/her natural action for the task. The instance of the ECEA led by using the ACS is a temporal extension which has the user keep a final state of a previous his/her action. We apply the temporal extension of the ECEA for a sweeping task. The high-level task, a cooperative task between the user and the robot can be realized. The robot with simple reactive behavior can sweep the region of under an object when the user picks up the object. In addition, we measure user's cognitive loads on the ECEA and a traditional method, DCM (Direct Commanding Method) in the sweeping task, and compare between them. The results show that the ECEA has a lower cognitive load than the DCM significantly.

Benzalkonium chloride is most commonly used as a preservative for ophthalmic solutions at a dosage of 50 μg/mL. In this study, we evaluated the antibacterial activity of this preservative against 16 species and64 clinically isolated strains. Benzalkonium chloride demonstrated a good effect on gram-positive cocci, the minimum inhibitory concentrations (MICs) of benzalkonium chloride to Staphylococcus epidermidis and Staphylococcus aureus including MRSA were less than 12.5μg/mL. On the other hand, benzalkonium chloride was not effective against gram-negative rods ; 95% (42/44) of gram-negative rods strains were not susceptible after treatment with 50μg/mL of benzalkonium chloride. Especially, the MICs of benzalkonium chloride to clinically isolated pseudomonas aeruginosa were over 200μg/mL. These results suggest that benzalkonium chloride as preservative for ophthalmic solutions in effective on gram-positive cocci even when used in concentrationsonly one fourth times as much as those commercially available and to gram-negative rods when used in concentrations which may cause damage to the comeas. The use of lower concentration of benzalkonium chloride may therefore make it possible to reduce the degree of damage to the cellular components of the cornea.
