High spin states in ^174Re are investigated via the ^152Sm（^27 AL,5nγ）^174Re reaction and γ - γ coincidence relationships are analysed carefully. A new band is identified due to its spectroscopic connection with the known π1/2^-[541] × ν1/2^-[521] band. This band is proposed to be the ground-state band built on the π1/2^-[541]× ,ν5/2^-[512] configuration in view of the low-lying intrinsic states in the neighbouring odd-mass nuclei. It is of particular interesting that the new band exhibits a phenomenon of low-spin signature inversion, providing a new situation for theoretical investigations.

Background: “Online Receipt Computer Advantage” (ORCA) surveillance, an online medical claim service produced and provided freely to medical facilities by the Japan Medical Association, has been available for public use since 2010. However, its preciseness has not been evaluated. The object of the present study is comparison with ORCA surveillance and prescription surveillance (PS), which is the most reliable daily surveillance for influenza nationwide in Japan, and evaluating preciseness of ORCA surveillance. Method: We specifically examined influenza as a targeted disease. We regarded PS as the gold standard daily real-time monitoring system for influenza nationwide and for each prefecture. This study assesses correlation and discrepancies between ORCA and PS results for influenza nationwide and by prefecture. Results: Nationwide, the correlation coefficient of PS and ORCA was 0.9653;the discrepancy rate was 27%. Among prefectures, results show that Mie and Fukui prefectures had two quite similar epidemic curves. Conclusion: Results demonstrate that ORCA surveillance is comparable to PS nationwide. However, some prefectures exhibited comparable results whereas others did not. ORCA surveillance cannot break down to the municipal level.

＜正＞Route-Information Based Prioritization（RIBP） scheme per VC（Virtual Connection） on ATM networks aims to improve both the total and minimum transmission-efficiency by reducing the total number of incomplete transmission cells（or packets）,especially for data transmission. RIBP gives the priority weighted by routeinformation -the location of nodes which make a connection,and cell drop probability on those nodes-for each VC,and operates prioritized queueing at output buffers with those *** simulated RIBP scheme on some network models and examined its *** also made a prototype which implemented RIBP for ATM networks,and confirmed its behavior.

For uniform tube inner coating of non-conductive thin films, the double-ended coaxial magnetron pulsed plasma (DCMPP) method was investigated. In this study, coating of TiN and TiO2 was performed. It was clearly shown that the extended anode effect was strongly influenced by the electric resistance of the coated thin films on the inner surface of an insulator tube. Additionally, high frequency (100 kHz) was better for relatively high plasma density. On the other hand, in the case of titanium oxide deposition, negative ion productions drastically decrease the deposition rate and the shifting velocity of plasma main position for coated TiO2 films.

A standard in-beam γ-spectroscopy experiment for 179Au has been performed via the 149Sm (35Cl, 5n) reaction at beam energies of 164-180 MeV. Based on the analysis of the experimental results, a rotational band built on the 1/2 [660](πi13/2) proton intruder orbital is established for 179Au for the first time. Systematic properties of the 1/2 [660](i13/2) band in odd-A Au nuclei are discussed, and the evolution of bandhead energy and deformation with changing neutron number are revealed.

Purpose: To present an application of the anisotropic diffusion (AD) method to improve the accuracy of the functional images of perfusion parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) generated from cerebral CT perfusion studies using multi-detector row CT (MDCT). Materials and Methods: Continuous scans (1 sec/rotation ×60 sec) consisting of four 5-mm-thick contiguous slices were acquired after an intravenous injection of iodinated contrast material in 6 patients with cerebrovascular disease using an MDCT scanner with a tube voltage of 80 kVp and a tube current of 200 mA. New image data were generated by thinning out the above original images at an interval of 2 sec or 3 sec. The thinned-out images were then interpolated by linear interpolation to generate the same number of images as originally acquired. The CBF, CBV and MTT images were generated using deconvolution analysis based on singular value decomposition. Results: When using the AD method, the correlation coefficient between the MTT values obtained from the original and thinned-out images was significantly improved. Furthermore, the coefficients of variation of the CBF, CBV and MTT values in the white matter significantly decreased as compared to not using the AD method. Conclusion: Our results suggest that the AD method is useful for improving the accuracy of the functional images of perfusion parameters and for reducing radiation exposure in cerebral CT perfusion studies using MDCT.

AIM： To assess the incidence and analyze the risk factors for Clostridium difficile-associated diarrhea （CDAD）after living donor liver transplantation （LDLT） in adult.METHODS： The micobiological data and medical records of 242 adult recipients that underwent LDLT at the Tokyo University Hospital were analyzed retrospectively. The independent risk factors for postoperative CDAD were identified.RESULTS： Postoperative CDAD occurred in 11 （5%）patients. Median onset of CDAD was postoperative d 19（range, 5-54）. In the multivariate analyses, male gender （odds ratio, 4.56） and serum creatinine （≥ 1.5 mg/dL,odds ratio, 16.0） independently predicted postoperative CDAD.CONCLUSION： CDAD should be considered in the differential diagnosis of patients with postoperative diarrhea after LDLT.

AIM： TO investigate the incidence and risk factors of late-onset acute rejection （LAR） and to clarify the effectiveness of our immunosuppressive regime consisting of life-long administration of tacrolimus and steroids. METHODS： Adult living donor liver transplantation recipients （n = 204） who survived more than 6 mo after living donor liver transplantation were enrolled. Immunosuppression was achieved using tacrolimus and methylprednisolone. When adverse effects of tacrolimus were detected, the patient was switched to cyclosporine. Six months after transplantation, tacrolimus or cyclosporine was carefully maintained at a therapeutic level. The methylprednisolone dosage was maintained at 0.05 mg/kg per day by oral administration. Acute rejections that occurred more than 6 mo after the operation were defined as late-onset. The median follow-up period was 34 too. RESULTS： LAR was observed in 15 cases （7%） and no chronic rejection was observed. The incidence of hyperlipidemia, chronic renal failure, new-onset post-transplantation diabetes, and deep fungal infection were 13%, 2%, 24%, and 17%, respectively. Conversion from tacrolimus to cyclosporine was required in 38 patients （19%）. Multivariate analysis revealed that a cyclosporine-based regimen was significantly associated with *** happen at a low incidence, supporting the safety and efficacy of the present immunosuppression regimen for living donor liver transplantation.
