| Abstract | 抗アレルギー剤（脱顆粒抑制剤）の1つであるtranilastの肥満細胞の遊離機序に対する抑制作用について検討を加えた。1．抗原刺激時の肥満細胞の(45)Ca uptakeおよびヒスタミン遊離に対して，tranilastは有意の抑制作用を示したが，comp.48/80刺激時にはtranilastの(45)Ca uptake，ヒスタミン遊離に対する抑制作用はほとんどみられなかった。2．phosphatidylserine添加時には，(45)Ca uptakeに対するtranilastの抑制作用は減弱傾向を示し，この傾向はヒスタミン遊離に対する作用に比べより高度であった。3．抗原および抗ヒトIgEによる好塩基球からのヒスタミン遊離に対して，tranilastは明らかな抑制作用を示さなかった。 |

| Abstract | Nb(2)O(5)-and Ta(2)O(5)-doped calcium si1icate glasses were soaked for various periods in a simulated body fluid(Kokubo solution) up to 30 days. Apatite formation ability of the surface of these glasses were investigated with thin-film X-ray diffraction and FT-IR reflection spectroscopy. The effects of these additive oxides on the bioactivity of CaO･SiO(2) based glass were discussed. A small amount of Nb(2)O(5) and Ta(2)O(5) suppressed the rate of silica hydrogel layer formation and the apatite formation on the surface of the glasses. The rate of the apatite nucleation on the surface of Nb(2)O(5)-doped calcium silicate glass was slower than that on the surface of Ta(2)O(5)-doped calcium silicate glass. It was concluded that the decrease in the apatite forming ability of calcium silicate glasses by these additive oxides is attributed to the suppression of formation of silica hydrogel layer which plays an important role in apatite nucleation. |

| Abstract | A square root (SQRT) algorithm in extension field F(p(m))(m = r(0)r(1)･･･r(n−1)･2(d), r(i) : odd prime, d : positive integer) is proposed in this paper. First, a conventional SQRT algorithm, the Tonelli-Shanks algorithm, is modified to compute the inverse SQRT in F(p(2d)), where most of the computations are performed in the corresponding subfields F(p(2i)) for 0 ≤ i ≤ d-1. Then the Frobenius mappings with addition chain are adopted for the proposed SQRT algorithm, in which a lot of computations in a given extension field F(p(m)) are also reduced to those in a proper subfield by the norm computations. Those reductions of the field degree increase efficiency in the SQRT implementation. The Tonelli-Shanks algorithm and the proposed algorithm in F(p(6)) and F(p(10)) were implemented on a Core2 (2.66 GHz) using the C++ programming language. The computer simulations showed that, on average, the proposed algorithm accelerated the SQRT computation by 6 times in F(p(6)), and by 10 times in F(p(10)), compared to the Tonelli-Shanks algorithm. |

| Abstract | As is well known, an advanced knowledge and know-how are needed in the design and the diagnosis work. Further, human experts can cope with the recent trend of customers needs. Therefore, the design and the diagnosis work have been privately performed in the past, and its information cannot be shared. In addition, the number of experts is decreasing. It is a very important problem to maintain and to extend experts technologies having been built up. For the purpose, methods and systems for technical inheritance of the advanced techniques of the skilled engineers are needed to train the unskilled operators and also can assist skilled operators. In this research, attention is focused on the design of analog filter circuit. To attain the target, the circuit structural classifier system to support design work is developed. Furthermore, simulation technology for hot strip rolling mills based on distributed agents is presented aimed to develop tools for the diagnosis of hot strip rolling mills operation. |

| Title Alternative | Evaluation Method of Total Risk and Additional Private Risk of Investment Project −Investment Criteria for Companies Considering Stakeholders Interest− |
| FullText URL | 41_2_021_038.pdf |

| Abstract | 機関投資家が資産運用としての証券投資を評価する場合と異なり、企業が事業投資を実施するかどうかの意思決定を行う場合、市場リスクのみをリスクとして評価するのは企業の実情に添わない。たとえば、企業の規模に比較し、取り上げる新規案件の規模が非常に大きく、仮にその案件が失敗した場合に企業自体の存立も危うくなるような場合、市場リスク以外に案件が抱える総リスク（total risk）の評価も重要な意思決定上のポイントとなるであろう。特に主要株主が分散投資していない集中投資家やオーナー経営者である場合、あるいは日本企業のように企業に経営資源をコミットしている経営者や従業員等の利害関係者（stakeholders）の立場も考慮している場合には、事業投資の意思決定を行う際、市場リスク料に追加個別リスクも含めた総リスクを評価して意思決定を行うことが求められるであろう。総リスクに含まれる追加リスク料としては、例えば、企業規模に伴うリスク料、業界別リスク料、カントリー・リスク料等が指摘され、実証的な計数化や検証がなされてきている。リスク評価の方法としては、リスク料をリスクフリー・レートに追加したリスク調整割引率で期待キャッシュフローを割り引いて現価を求める方法と、期待キャッシュフローからリスク額を控除した確実性等価を求め、リスクフリー・レートで割り引いて現価を求める方法がある。前者の方法は「リスク調整割引率法」であり、実務では「Build−up法」や「追加リスクを加えたCAPM 法」が用いられている。後者の方法は「確実性等価法」であり、理論的には前者よりも優れているとされるが、実務ではあまり採用されていないのが実情である。この研究ノートでは、①リスク調整割引率法で割引率に追加する追加リスク料と、確実性等価法で控除される個別リスク額の相互の関係を検討し、案件評価における両手法の互換性を検討した。また、②実務上必要となる、追加個別リスク料の見積もり方についての検討も行った。最後に、③利害関係者を重視した企業の事業投資の意思決定または評価基準についての検討も行った。 |

| Abstract | Optical-fiber multi-level PCM transmission system is investigated on the transmission distance and bit rate. A communication channel is established as follows: a light signal is modulated in intensity with a completely-balanced M-Ievel code at a transmitter, and is propagated over an optical glass fiber, and is demodulated at a receiver where the signal with an additive noise is processed through a PD, an equalizing amplifier, a matched filter, (M-l) comparators and a decision circuit. The relative power of the noise from the amplifier is increased in accordance with the reciprocal of fiber's transmittance, where shot noise and thermal noise are smoothed and decreased in power by the matched filter. The relation between the BER and the SNR leads the transmission distance. The product of the transmission distance and bit rate takes the large maximum at the large values of SNR and M. The large value of M is suitable for low-speed and high-rate system, and the interference system. |

| Abstract | Three methods for determining chemical oxygen demand (COD) by means of flow injection analysis (FIA) with potassium permanganate, potassium dichromate, or cerium(IV) sulfate as oxidant, developed in this laboratory, are described from the point of view of their operating properties. The permanganate method is the most sensitive and common, but forms manganese(IV) oxide precipitate which blocks the FIA lines and connectors. Addition of phosphoric acid in the reagent system is, however, effective to some extent in order to avoid blocking the flow system. The dichromate method is the most workable and stable, but produces toxic wastes containing chromium(VI). The cerium method is the most probable because cerium(IV) is the strongest oxidant of the three and less poisonous. The last method with cerium(IV) sulfate is therefore recommendable to apply to the continuous monitoring of COD in many situation. |
