  • At the conclusion of a double-blinded, randomized clinical trial of propranolol hydrochloride, but before un blinding, the patients and clinic personnel were asked to guess the treatment group assignment of each patient. While 79.9% of the patients receiving propranolol correctly Identified their treatment group assignment, 57.2% of the patients receiving placebo incorrectly guessed that they were aiso in the propranolol group. No specific mechanism was identified to explain why more patients receiving propranolol were better able to guess' their group assignment. Clinic physicians correctly identified the group assignment of 69.9% of the patients receiving propranolol and 68.8% of the patients receiving placebo. Clinic coordinators correctly identified the group assignment of 67.1% of the patients receiving propranolol and 70.6% of the patients receiving placebo. For clinic personnel, heart rate level and heart rate change seem to be the mechanisms employed to Identify their patients' treatment assignment.

  • A technology of ultrasonic biotelemetry for tracking fish behavior is investigated. The ultrasonic biotelemetry system is constituted by a transmitter and a receiving system. Because a pinger was mainly used for the transmitter, the capability for pinger to possess was investigated and the efficient usage for pinger was examined. A source pressure level and a frequency were synthetically examined so that pinger could realize small size, a light weight, and a long life time. The receiving system is divided roughly into directional hydrophone systems and acoustic positioning systems by the receiving method. The directional hydrophone system is divided into single beam and multiple beam with the number of hydrophone, and the acoustic positioning systems is divided into LBL (Long Base Line), SBL (Short Base Line), and SSBL (Super Short Base Line) on the basis of base line. The present situation, the merits and demerits, and the principle of each receiving method were investigated in detail, and the efficient usage for each receiving method were examined.

  • The present study was to carried out to investigate the anti-stress effects of Samhwasan in immobilized rats. Serum levels of catecholamine and aldosterone were measured in immobillzed rats orally receiving extracts of Samhwasan, respectively, for 1 day 7 days. And in order to investigate the analgesic effects of Samhwasan in acetic-acid injected mice, the writhing syndrome frequency was measured. The results obtained were summarized as follow ; 1. There were decreases of norepinephrine in rats receiving Samhwasan for 1 and 7 days respectively. 2. There were decreases of epinephrine in rats receiving Samhwasan for 1 day and 7 days respectively, and significant decreases were recognized in rats receiving Samhasan for 7 days. 3. There were significant decreases of aldosterone in rats receiving Samhwasan for 1 day and 7 days respectively. 4. There were significnat decreases of writhing syndrome frequency in mice receiving Samhwasan. These results appeared to suggest that Samhwasan produce the anti-stress effects and effects on pain relief.

  • This study proposes a receiving pad identification coil for wireless charging of electric vehicles. The proposed coil identifies the shape of the receiving pad through magnetic coupling with the receiving pad. Therefore, the shape of the coil is designed to show the different magnetic properties of each receiving pad. The accuracy of this design is verified through finite element method simulation. Furthermore, the operation method of the secondary pad identification circuit is described, and the appropriate magnitude and length of the pulse voltage applied to this circuit for receiving pad identification are derived through simulation. The performance of the proposed identification coil set is verified by the experimental results.

  • CP (Cellular Phone) is currently one of the most attractive technologies and RT (Robot Technology) is also considered as one of the most promising next generation technology. We present a new technological concept named RCP (Robotic Cellular Phone), which combines RT and CP. RCP consists of 3 sub-modules, $RCP^{Mobility}$, $RCP^{Interaction}$, and $RCP^{Integration}$. $RCP^{Interaction}$ is the main focus of this paper. It is an interactive emotion system which provides CP with multi-emotional signal receiving functionalities. $RCP^{Interaction}$ is linked with communication functions of CP in order to interface between CP and user through a variety of emotional models. It is divided into a tactile, an olfactory and a visual mode. The tactile signal receiving module is designed by patterns and beat frequencies which are made by mechanical-vibration conversion of the musical melody, rhythm and harmony. The olfactory signal receiving module is designed by switching control of perfume-injection nozzles which are able to give the signal receiving to the CP-called user through a special kind of smell according to the CP-calling user. The visual signal receiving module is made by motion control of DC-motored wheel-based system which can inform the CP-called user of the signal receiving through a desired motion according to the CP-calling user. In this paper, a prototype system is developed for multi-emotional signal receiving modes of CP. We describe an overall structure of the system and provide experimental results of the functional modules.

  • Single nuclei from two-, four- and eight-cell mouse embryos were transplanted into enucleated two-cell mouse embryos by micromanipulation and sendai virum mediated fusion. no significant difference in successful injectin rate and fusion rate was found between the cell stages of nuclear donor embryos. There nuclear transplant embryos receiving different cell stage nuclei were cultured in vitro for 96 hours. 75.3% of 255 embryos receiving 2-cell nuclei, 68.2% of 236 embryos reciving 4-cell nuceli and 46.9% of 228 embryos receiving 8-cell nuclei were developed to blastocyst, respectively. The number of blastomeres was significantly(P<0.05) reduced in the embryos receiving 8-cell nuclei, compared with the embryos receiving 2-cell, 4-cell nuclei or the intact embryos. Also the size of blastocysts was significantly(P<0.05) smaller in the embryos receiving 8-cell nuclei, compared with the intact or other nuclear transplant embryos. These results suggest that single nuclei introduced into the enucleated two-cell embryos are able to support the in vitro development of the reconstituted embryos to blastocysts. The prominant retardation of blastocoele formation and cell division was shown in nuclear transplant embryos receiving eight-cell nuclei when they were cultured in vitro.

  • In this paper, we analyzed the efficiency of magnetic resonance wireless power transmission (WPT) using superconductor coil according to the changing position of transmission and receiving coils. We implemented a WPT system using a magnetic resonance at a frequency of 63.1 kHz. Transmission and receiving coils using superconductor coil were wound on a spiral manner of diameter 100mm. For comparison, transmission and receiving coils using normal conductor coil were designed under the same condition. At a distance of 50mm, we measured efficiency when transmission-receiving coils were matched 25%, 50%, 75% and 100%. When a superconductor coil was applied to the transmission and receiving units, efficiency of WPT was very high. In addition, in the case of the superconducting transmission-receiving coils, when coils matched 100% the efficiency was 30% and matched 25% the efficiency was 8%.
