Shotaro Ohno,Takashi Takimoto 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10
Line marking take an important role in the official game of sports. In addition, high skill is necessary for processing a line having a long distance. In this paper, We have developed an automatic line marker robot that draws constant and high quality lines. Then, the developed robot can make a straight line and a circle. By recognizing landmarks, this robot can revise the way it is going. The developed robot is attached one motor for steering, two motors for throttle, the manual-type line marker made by molten Corporation, and sensors such as encoders for motors and LiDAR (Light Detection and Ranging). Then, we have shown experimental results that illustrate the effectiveness of the proposed control method.

<P><B>Abstract</B></P><P>Endocannabinoids mediate retrograde signal and modulate transmission efficacy at various central synapses. Although endocannabinoid release is induced by either depolarization or activation of G<SUB>q/11</SUB>-coupled receptors, it is markedly enhanced by the coincidence of depolarization and receptor activation. Here we report that this coincidence is detected by phospholipase Cβ1 (PLCβ1) in hippocampal neurons. By measuring cannabinoid-sensitive synaptic currents, we found that the receptor-driven endocannabinoid release was dependent on physiological levels of intracellular Ca<SUP>2+</SUP> concentration ([Ca<SUP>2+</SUP>]<SUB>i</SUB>), and markedly enhanced by depolarization-induced [Ca<SUP>2+</SUP>]<SUB>i</SUB> elevation. Furthermore, we measured PLC activity in intact neurons by using exogenous TRPC6 channel as a biosensor for the PLC product diacylglycerol and found that the receptor-driven PLC activation exhibited similar [Ca<SUP>2+</SUP>]<SUB>i</SUB> dependence to that of endocannabinoid release. Neither endocannabinoid release nor PLC activation was induced by receptor activation in PLCβ1 knockout mice. We therefore conclude that PLCβ1 serves as a coincidence detector through its Ca<SUP>2+</SUP> dependency for endocannabinoid release in hippocampal neurons.</P>

Over 3000 cancer patients have already been treated with 140- to 400-MeV/n carbon beams produced by the heavy ion medical accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS) since 1994. These clinical results have clearly verified the advantages of carbon ions. Based on our experience at HIMAC, a hospital-specific facility optimized for carbon-ion therapy has been designed. The prototype developments of an electron cyclotron resonance (ECR) ion source, a radio frequency quadruple (RFQ) linac, an inter digital H (IH) linac, an acceleration system of synchrotron, a beam-delivery system and other key-technology parts have been successfully finished. Thus, in co-operation with NIRS, Gunma University has been constructing a carbon-therapy facility since April, 2006. If the present clinical results are to be improved, it is necessary to create a more accurate dose distribution on tumors without an undesired dose being deposited in normal tissue. Beam-scanning methods with respiration-gated irradiation are especially important to treat a cancer tumor located in the trunk of a patient.

YUKI OKIGAWA,TAKEO UMESAKA,YUTAKA OHNO,SHIGERU KISHIMOTO,TAKASHI MIZUTANI 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2008 NANO Vol.3 No.1
We have measured the potential distribution on carbon nanotube (CNT) field-effect transistors (FETs) using electrostatic force microscopy (EFM) and Kelvin probe force microscopy (KFM). Clearer potential profiles were obtained by EFM than by KFM. When the CNT-FET is in the ON state, the EFM image shows uniform potential distribution along the CNT. In contrast, when the CNT-FET is in the OFF state, nonuniform potential image with dark spots are obtained. The dark spots can be attributed to the defects in the CNTs.
51V-NMR Study of the Quasi-one-dimensional Antiferromagnet BaCo2V2O8

We have investigated the magnetic properties of quasi-one-dimensional antiferromagnetBaCo2V2O8 by the measurements of 51V-NMR spectrum. With decreasing temperature, Kk showsa broad peak around 30 K signaling the 1D short-range order in the Co2+ spin chain. The estimatedWeiss temperature Θ = −105 K, hyperfine coupling constants Akhf = 2.1 kOe/µB for H k c and Ahf= 2.6 kOe/µB for H ⊥ c at 13 kOe are comparable to those at 70.6 kOe. These results suggest thatstatic magnetic properties in the paramagnetic state are nearly independent of external magneticfield, although the ground N´eel state is suppressed by the application of external magnetic fieldabove Hc = 39 kOe along c-axis. In the antiferromagnetic state below TN = 5.4 K, the doublerectangle-like powder pattern was observed, indicating two V sites exposed to different size of internalfields, HA1 = 2.1 and HA2 = 3.8 kOe. The internal fields at V sites are explained by takinginto account of the classical and pseudo-dipolar fields from Co2+ magnetic moments.
NMR Study of Successive Magnetic Transitions in the A-site Ordered Perovskite LaMn3Cr4O12

We have investigated the successive magnetic phase transitions of the A-site ordered perovskiteLaMn3Cr4O12 by measuring 139La nuclear magnetic resonance (NMR) spectra. The successivemagnetic transitions are revealed by a very small but clear increase in the full width at half maximum(FWHM) of the 139La NMR signal at TM2 = 150 K and by the disappearance of the signal due to theline broadening at temperatures below TM1 = 50 K. These two magnetic transitions are associatedwith independent orderings within the Cr-site sublattice at TM2 and within the Mn-site sublatticeat TM1. Regarding the magnetic structure of the Cr-site sublattice at temperatures below TM2, thecancellation of internal fields at the La site, ruling out ferromagnetic and multi-q antiferromagneticstructures, is consistent with the typical antiferromagnetic structure for perovskites, such as G-,A- and C-type orders. The uncanceled internal field at the La site at temperatures below TM1is also consistent with these typical antiferromagnetic structures in the Mn-site sublattice. Thedifferences in the temperature dependences of the Knight shift K(T) and the bulk susceptibility χ(T) are consistently explained by the independent magnetic orderings of the Cr- and the Mn-sitesublattices and the cancellation of internal field originating from the Cr-site sublattice at the Lasite at temperatures below TM2.

Adrenal venous sampling (AVS) is the key procedure for lateralization of primary hyperaldosteronism (PA) before surgery. Identification of the adrenal veins using computed tomography (CT) and intraoperative cortisol assay facilitates the success of catheterization. Although administration of adrenocorticotropic hormone (ACTH) has benefits such as improving the success rate, some unilateral cases could be falsely diagnosed as bilateral. Selectivity index of 5 with ACTH stimulation to assess the selectivity of catheterization and lateralization index (LI) >4 with ACTH stimulation for unilateral diagnosis is used in many centers. Co-secretion of cortisol from the tumor potentially affects the lateralization by the LI. Patients aged <35 years with hypokalemia, marked aldosteroneexcess, and unilateral adrenal nodule on CT have a higher probability of unilateral disease. Patients with normokalemia, mild aldosterone excess, and no adrenal tumor on CT have a higher probability of bilateral disease. Although no methods have 100% specificity for subtype diagnosis that would allow bypassing AVS, prediction of the subtype should be considered when recommending AVSto patients. Methodological standardization and strict indication improve diagnostic quality of AVS. Development of non-invasiveimaging and biochemical markers will drive a paradigm shift in the clinical practice of PA.

Although cardiac rehabilitation (CR) has been shown to improve exercise tolerance and prognosis in patients with cardiovascular diseases, there remains low participation in outpatient CR. This may be attributed to the patients’ busy schedules and difficulty in visiting the hospital due to distance, cost, avoidance of exercise, and severity of coronary disease. To overcome these challenges, many countries are exploring the possibility of remote CR. Specifically, there is increasing attention on the development of remote CR devices, which allow transmission of vital information to the hospital via a remote CR application linked to a wearable device for telemonitoring by dedicated hospital staff. In addition, remote CR programs can support return to work after hospitalization. Previous studies have demonstrated the effects of remote CR on exercise tolerance. However, the preventive effects of remote CR on cardiac events and mortality remain controversial. Thus, safe and effective remote CR requires exercise risk stratification for each patient, telenursing by skilled staff, and multidisciplinary interventions. Therefore, quality assurance of telenursing and multi-disciplinary interventions will be essential for remote CR. Remote CR may become an important part of cardiac management in the future. However, issues such as cost-effectiveness and insurance coverage still persist.
