抄録 Sedatives are administered during extracorporeal membrane oxygenation (ECMO) therapy to ensure patient safety, reduce the metabolic rate and correct the oxygen supply-demand balance. However, the concentrations of sedatives can be decreased due to absorption into the circuit. This study examined factors affecting the absorption of a commonly used sedative, midazolam (MDZ). Using multiple ex vivo simulation models, three factors that may influence MDZ levels in the ECMO circuit were examined: polyvinyl chloride (PVC) tubing in the circuit, use of a membrane oxygenator in the circuit, and heparin coating of the circuit. We also assessed changes in drug concentration when MDZ was re-injected in a circuit. The MDZ level decreased to approximately 60% of the initial concentration in simulated circuits within the first 30 minutes. The strongest factor in this phenomenon was contact with the PVC tubing. Membrane oxygenator use tended to increase MDZ loss, whereas heparin circuit coating had no influence on MDZ absorption. Similar results were obtained when a second dose of MDZ was injected to the second-use circuits.

抄録 There is increasing interest in the intrinsic activity of the resting brain, especially the activity slower than 0.1Hz (i.e., low-frequency oscillations, or LFOs). To investigate the origin of LFOs observed in functional near-infrared spectroscopy (fNIRS), we recorded multichannel fNIRS and electroencephalography (EEG) from the frontal cortex of 11 healthy young volunteers in the resting state. Electrocardiography (ECG), electro-oculography and respiration were also measured. Synchronous oscillations of oxy-hemoglobin (oxy-Hb) around 1.0Hz were detected in all fNIRS channels, and their frequency was consistent with a peak frequency of ECG, suggesting the changes of cerebral blood flow due to heart beats. In addition, oxy-Hb oscillations around 0.1Hz (i.e., LFOs) appeared in the fNIRS. The channels where LFOs appeared differed among the subjects, and the LFOs appeared or disappeared even in the same fNIRS channels. The appearance of LFOs in fNIRS channels was significantly higher when the LFOs appeared on the EEG in the adjacent EEG electrodes compared to when LFOs did not appear on EEG. The amplitude and coherence (synchronicity) of the LFOs were increased by changing the subjects' position from dorsal to the sitting position in both fNIRS and EEG, and the coherence in particular was increased in the homologous fNIRS channels on the bilateral hemispheres. These results suggest that LFOs of oxy-Hb couple with resting-state EEG activity.

抄録 In adult high-frequency oscillatory ventilation (HFOV) with an R100 artificial ventilator, exhaled gas from patientʼs lung may warm the temperature probe and thereby disturb the humidification of base flow (BF) gas. We measured the humidity of BF gas during HFOV with frequencies of 6, 8 and 10Hz, maximum stroke volumes (SV) of 285, 205, and 160ml at the respective frequencies, and, BFs of 20, 30, 40l/min using an original lung model. The R100 device was equipped with a heated humidifier, HummaxⅡ, consisting of a porous hollow fiber in circuit. A 50-cm length of circuit was added between temperature probe (located at 50cm proximal from Y-piece) and the hollow fiber. The lung model was made of a plastic container and a circuit equipped with another HummaxⅡ. The lung model temperature was controlled at 37℃. The HummaxⅡ of the R100 was inactivated in study-1 and was set at 35℃ or 37℃ in study-2. The humidity was measured at the distal end of the added circuit in study-1 and at the proximal end in study-2. In study-1, humidity was detected at 6Hz (SV 285ml) and BF 20l/min, indicating the direct reach of the exhaled gas from the lung model to the temperature probe. In study-2 the absolute humidity of the BF gas decreased by increasing SV and by increasing BF and it was low with setting of 35℃. In this study setting, increasing the SV induced significant reduction of humidification of the BF gas during HFOV with R100.

抄録 Suppression of common-mode current is important to achieve electromagnetic compatibility of high-speed and high-density electronic circuits. The authors have focused on the common mode current flowing on a printed circuit board (PCB) to explain the excitation mechanism. A narrow ground pattern in microstrip structure excites common-mode current. In the previous paper, the authors explained the mechanism of common mode generation by means of "current division factor" for simple PCBs. The estimated radiation from a simple PCB agreed well with measured one. In this paper, the authors extend the theory to be applied to generalize ground structure. The validity of the theory is confirmed by comparing the measured radiation and the estimated value using the common-mode model for a test PCB. The estimated radiation agrees well with the measured one within 3 dB up to 900 MHz.

タイトル(別表記) An Introductory Economic Study on Innovation -The Case of Manufacturing Industry-
フルテキストURL oer_036_4_001_013.pdf

抄録 The most important word is ‘innovator’ in the theory of Shumpetarian Hypothesis. That gives rise to the specific rivalry and competitive power in some vital facets of business fluctuation. This rivalry has both the innovative and strategic characteristics inside the firm. The notorious industrial policies used to depend on the good functions of production-investment circuit and cost-price one. None the less market fails. A series of the recent open market operations implemented by Japanese Central Bank, are related to a certain misunderstanding about our popular macroeconomic analysis. Let there be no mistake about it. In this article I will research the sustainable factors of R&D and the revised chain model inside the a few manufacturing firms and / or industries including semi-conductor industry. Besides we are going to make use of Japanese statistical materials about TFP comparing to those of U.S. and others as occasion demands. We can take notice that this work has some important fact findings in the article. Finally there will be explanation and emphasis about the distinguishing method between the firms of three types and the ‘inside’ problem.

抄録 The author tried to measure RaB, RaC and ThB in the hot spring waters using G-M counter and proved the existence of RaB and ThB in Misasa Hot Springs. To 100 liters of spring water ahout 20 gms of ferric chloride and then sodium hydroxide were added. Precipitate was dissolved in hydrochloric acid and after adding bismuth and lead, the solution was saturated with hydrogen sulfide. The precipitate of sulfides was filtered and ignited to ashes after drying. The β-activity of the ashes was measured by a mica-window type G-M counter with the recording circuits of scale of 16. Natural background was 50±5 connts per minutes. Six spring waters of Misasa, namely "Spring of Branch Laboratory", "Nakayu", "Gunze" "O-T-R", "Jwayu", and "Tsukiminoyu" were investigated. RaB was detected in all samples. ThB was found only in "Gunze" and "O-T-R". ThB content of "Gunze" was estimated, to be roughly 1×10(-12) Curie units per liter.
