In this paper, we examine a Spherical Ultrasonic Motor(SUSM) for the haptic display system. Experimental system consists of a force sensor and a SUSM comprising one spherical rotor and three ring-shaped stators. The stator is made from an elastic body and piezoelectric elements for vibration. The stators and the rotor are in pressure contact with each other. The frequency and the phase difference the stators" vibration can be controlled and we can generate torque of the rotor. Some experiments were briefly investigated to examine the performances of the proposed haptic display method.

To clarify the factors influencing the physical properties of fish after heat treatments, we investigated changes in the properties of proteins in the dorsal ordinary and dark muscle of yellowtail (Seriola quinqueradiata) heated under different conditions commonly used for the purposes of food hygiene. High-temperature/short-time heating (85℃ for 90 s and 75℃ for 60 s) affected the protein solubility more than low-temperature/long-time heating (63℃ for 30 min). Sodium dodecyl sulphate-polyacrylamide gel electrophoresis and differential scanning calorimetry showed that low-temperature/long-time heating reduced the degree of actin denaturation in fish compared with that by other heating conditions. In addition, collagen solubility was enhanced with low-temperature/long-time heating. Therefore, these results suggest that differences in the degree of actin and collagen denaturation are responsible for the enhanced meat tenderness and diminished meat shrinkage, resulting from low-temperature/ long-time heating.

본 논문의 목적은 매립지와 매립지 주변환경에 대해서 송사리를 사용하여 실제 내분비교란물질에 대한 모니터링 시스템을 수립하는데 있으며, 그 모니터링 시스템은 2개phase 구성되어 있다. 첫번째 phase는 물에 대한 실험이며, 두번째 phase는 생태적 모니터링이다. 본 논문에서는 첫번째 phase에 관해서 나타내었으며, 이 실험에서는 처리되지 않는 침출수와 고도 처리된3가지(전기투석, 역삼투압, DT module system)의 침출수를 사용하여 실험을 실시하였다. 이때의 침출수는 일본의 若 松區北九州市에 위치한 매립지의 침출수를 이용하였다. 실험항목은 송사리의 태아, 치어, 성어의 급성 독성, 송사리의 생산성, 에스트로젠 활성도로써의 vitellogenesis 실험을 실시하였으며, 침출수의 의독성은 TOC농도에 따라 증가하였다. 송사리의 치어는 침출수의 독성 지표로 유용하였다. 비록, GC/MS를 이용하여 EDCs로 의심되는 물질이 검출될지라도, 처리되지 않은 침출수로부터의 2주간 노출시 vitellogenin는 유도되지 않았다. HIS는 희석된 침출수 (TOC 농도 107, 214mg/l)에 노출시 증가하였다. 침출수는 강한 복합독성을 가지고 있으므로, 오직 vitellogenin 변형만으로 침출수를 평가하기에는 어려움을 가지고 있으며, 생상성과 vitellogenesis는 2%농도에서 1-2주일간의 노출시 어떤 영향도 없었다. 고도처리된 침출수는 급성독성, 생산성과 vitellogenesis의 변화가 없었다. Our study aims to establish a practical monitoring system by using Japanese Medaka (Oryzias latipes) for drainage from a landfill site and the environment around k. The monitoring system consists of 2 phases. The first phase is water testes, and the second phase is ecological monitoring. In this paper, we reported the first phase. We carried out the first phase experiment using untreated leachate and treated leachate processed by 3 types of advanced processes (Electric dialysis, RO, and DT module system). Untreated and treated leachate from the processing plant, Wakamatsu-ku, Kitakyushu city, Japan was used. The test items were acute toxicity of embryo, juvenile and adult, fecundity, and vitellogenesis as an estrogenic activity. Toxicity of leachate increased according to TOC concentration. Juvenile of Medaka was a very useful indicator of the toxicity of the leachate. No vitellogenin was induced after 2 weeks exposure to untreated leachate, although suspected EDCs were detected by GC/MS or targeted analysis. HSI increased in the case of exposure to diluted leachate (TOC concentration, 107, 214 mg/l). As the leachate has strong complex toxicities, it is difficult to evaluate the leachate by vitellogenin inducing only. Fecundity and vitellogenesis ware not effected by exposure to 2% concentration of leachate for 1 and 2 weeks exposure. Advanced treated leachate induced no acute toxicity, vitellogenesis, and reproduction.
