Dentists and dental hygienists remove dental calculus using a cutting tool called dental scaler. The evaluation of sharpness of dental scalers requires skill which depends on sensory examination. The aim of this research is to evaluate the sharpness of scalers objectively by estimating optical reflection images of blades rotated in two directions. For taking photos of blades at various angles using CCD camera, the scaler to be inspected was fixed on a turn table driven by a stepping motor. In this research, the angle of a scaler fixture on the turn table was also changed by a RC servo motor. As a result, the optical reflection patterns of the cutting edge could be obtained more precisely than before. Next, an image processing method was examined for calculating the area and the length of optical reflection patterns of the cutting edge from the photos obtained from various angles. And the relation between these values and the sensory evaluated values was examined using multiple regression analysis. As a result, it was confirmed that this method can evaluate the sharpness of scalers objectively and precisely. And it was also confirmed that the angle of the scaler fixture is also an important factor for this evaluation method as well as the angle of the scaler.

Application of high brightness LED as the light source for colors to the electric display or lighting equipment is expected.
The simple circuit, which can handle from 1 to 10 LED of various colors driven in the most suitable state without changing a circuit constant, is proposed. We obtained how to mix varied colors emitted from LED, and the generation of patterns on indicator by the color materials such as ink and paint. We produced electric display experimentally in order to confirm visibility of color or luminosity of mixing of various colored light.
The display constituted with a light guide and indicator, a number of LED was installed in the side or in the backside of the light guide. Indicator is placed upon an upper side of the light guide. The letter, which was drawn on an indicator urface with green ink, twinkles by the luminous flux of LED of blue beautifully.

保管料計算要素としての在庫量測定は、旧認可料金では常温系が10日単位、冷蔵系が15日単位であったが、在庫回転率を高める努力をしている顧客ニーズに合わなくなってきている。
一方で物流料金を倉庫・運送等を含めた包括的 (一気通貫) で、通過金額歩率とする要求が高まっている。この場合、時間要素としての保管滞留期間をどう料金に反映させるかは物流事業として極めて重要であり、この考え方に立った新しい保管料契約方式について考察する。その基本は所定期間中の在庫日数に通過物量と日当り保管原価を連動させたものである。

3PLビジネスにおいては、商流の決済方式に準じた商品通過金額の歩率 (%) で委託料金契約を締結することが多く、受託事業者の採算管理を困難にしている。それは従来の物流原価要素とはおよそかけ離れた商品価額のスライドであり、さらに包括的な一気通貫業務としての単純一律設定で事業リスクが極めて大きくなる。
この採算確保にはまず与えられた物流条件を精査し、受託業務範囲を明確化してコストに落とし込み、契約期間内での条件変化を許容し得る範囲を設定しなければならない。厳密には活動基準原価計算 (ABC) によるべきだが、コンペに対応する迅速な簡易型査定方式を持つ必要がある。またこのような変動型契約方式では事業コスト構造を変動的なものとする等、多くの業務改革が不可欠となる。

The object of this study is to conduct mechanical evaluation judgments of the ability of people to maintain balance in a standing posture. The authors developed a system which swings a plate on which a person is standing and measures the resulting plate torques and the angles of inclination of each part of the body element at that time (Posture Control System). This swing generator generates smooth rolling and pitching movements, and the movement cycle and direction can be changed freely with an N. C. controller. As a major characteristic of this system, changes of balance caused by swing disturbances such as changes of torque acting in the plate can be measured. This actuator (blush less servo motor) is used not only to generate motions but to serve the function of torque sensor. Small torque balance inclinometers are used to measure the angles of inclination of each part of the body (12 sections). Moreover, a tri-dimensional model of the body is constructed to calculate the center of gravity and center of force operating in each part of the body. In this report, the authors used this Posture Control System and tried the following: 1) Evaluation of ability of normal healthy old people to maintain balance in a standing posture by torque of the sole. 2) Evaluation of learning phenomena by fuzzy linear regression analytical methods for general evaluation of standing ability. Tests of evaluation of the traceability were conducted with normal young healthy people as well as with normal old healthy people as subjects. Tests under the same conditions in which people swung the plate while standing on two legs showed the following characteristics. In the old people, width and standard deviation of delay for distance (dθ) were large, and the average of dθ was large in the negative direction. The old people fell far below the young people in traceability of balance for a change of swing direction. Moreover, for individuals with unknown functional disorders, learning phenomena are discussed in the framework of possibility; the authors employed the fuzzy regression model to analyze learning phenomena. This approach enables us to understand two characteristics of the learning effect. One is the formation of competence at swing disturbance. The other is stability. For example, young and old people are much the same at the formation of competence. But the old people are inferior to the young in stability. In rehabilitation training, the results of training can be expected in the future as each handicapped person has his own aim. It is considered a useful application to conduct a measuring experiment for many subjects and to change the results into a data base in this system.

甲状腺髄様癌の診断に血清カルシトニン測定は有用な検査である。しかし，わが国では欧米で使用している高感度キットが認められず，感度，特異度が劣っているカルシトニン測定キット（カルシトニンRIA「

アイM」）が使用され続けてきた。今回，国際標準品IRP WHO Reference Standard 89/620に準拠したヒト・カルシトニン（hCT）測定キット“エクルーシス試薬カルシトニン”（Roche Diagnostics GmbH社）が開発され使用ができるようになった。

本測定キットは欧米で使用されている測定キットと同様に高感度であり，また，RI施設を必要としないNon-RIA化された電気化学発光免疫測定法（ECLIA）を用いたサンドイッチイムノアッセイで，18分での迅速測定が可能である。

今後，わが国の血清カルシトニン測定の主流になっていくものと考えられる。

Drag reduction caused by cationic surfactant solutions is considered to be an effective way to reduce the running cost in closed-loop district heating and cooling systems. Conversely, much research has pointed out that heat transfer reduction occurs simultaneously for drag reducing flows. In this study, heat transfer characteristics were measured for drag-reducing additives with two cationic surfactants (Ethoquad O/12 and Ethoquad O/13) using a test loop equipment and a practical air conditioning system. From the results, significant decreases of heat transfer coefficients were observed for drag-reducing additives, however, temperature difference between the inlet and outlet of the test section can not be decreased compared with that of water.
