    Void formation and structure change by heavy ion irradiation were investigated in GaSb and InSb thin films. The voids were formed after irradiation in both materials. The average diameter of the voids was about 15nm in GaSb and 20nm in InSb irradiated with 60 keV Snþ ions to a fluence of 0:25 x 1018 ions/m2 at room temperature. The void size in InSb is larger than that in GaSb. The large void size is quantitatively explained by the amount of induced vacancies obtained by the SRIM code simulation. The Debye-Scherrer rings were observed in the SAED patterns on both materials. The structure changes into a polycrystal by ion irradiation. Additionally, the 200 superlattice reflections in the [001] net pattern were almost absent, and the streak pattern along the h110i direction was observed in InSb. It is considered that the anti phase domains of different lengths are formed by ion irradiation. Ion irradiation transforms the structure of InSb from chemical ordering to chemical disordering via the formation of anti phase boundaries

    The purpose of this paper is to clarify the characteristics and problems of the outcome compensation system in teacher evaluation of A prefecture as a preliminary study of research on " degree of consent" of the outcome compensation system. The findings obtained are as follows. There are "reflecting on pay raise after 10 years experience training-protection of young teachers ", " evaluation group consisting of all faculty members excluding managers ", and " grouping of upper grades ·avoidance of fixation of upper grades by discretion of principal·"as characteristics of the outcome compensation system of A prefecture. There are " uncertainty of negotiation/ decision process ", " inconsistency with faculty members' view of teachers and self-esteem ", "vulnerability of manager' s evaluating ability and fairness / fairness ", " alteration of collaboration and collegiality in faculty staff group , "" decline of motivation by deviation from self evaluation and promotion of business ", " unreasonableness of segment selection by mixing position and job category" and" immobilization of upper grades in case "as problems of outcome compensation system in A prefecture. Finally, we presented the problems and perspectives concerning future survey research with a view on "degree of consent ".本研究は,平成29年度公益財団法人日本教育公務員弘済会本部奨励金及び JSPS:17K04623の助成を受け,実施されたものです

    A Study on the Physical Sensations of Four Kinds of Trial Toothbrushes and Four Different Toothbrushing Methods

    Get PDF
    Using 65 students of the hygiene school attached to Matsumoto Dental College (35 first-year students, 30 second-year students) as subjects, we performed an investigation into the different physical sensations produced when using 4 trial toothbrushes and 4 different toothbrushing methods. The conclusions are as follows: 1. "Length of brush": There was a tendency to reply that the length of brush seemed slightly shorter when the students brushed with the Roll method, rather than the other three methods. 2. "Stiffness of filaments": There was a tendency to reply that the bristle was much harder when the students brushed with methods from Group B (Methods that primarily use the tip of the bristle) than with methods from Group A (Methods which use the side of the bristle). 3. "Tooth brush wear": A large percentage of students replied that the bristle was more durable when using methods from Group B rather than Group A. 4. "Physical sensation on tooth and gingiva": Brush M and the Open-tufted brush, both classified as "medium" stiffness, were preferred. 5. "Physical sensation of holding the handle": 80-90% of the students, regardless of the toothbrushing method employed, liked the handles of the brushes

    Severity-based treatment for Japanese patients with MPO-ANCA-associated vasculitis: the JMAAV study

    We (JMAAV [Japanese patients with MPO-ANCA-associated vasculitis] Study Group) performed a prospective, open-label, multi-center trial to evaluate the usefulness of severity-based treatment in Japanese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibodies (MPO-ANCA)-associated vasculitis. Patients with MPO-ANCA-associated vasculitis received a severity-based regimen according to the appropriate protocol: low-dose corticosteroid and, if necessary, cyclophosphamide or azathioprine in patients with mild form; high-dose corticosteroid and cyclophosphamide in those with severe form; and the severe-form regimen plus plasmapheresis in those with the most severe form. We followed up the patients for 18 months. The primary end points were the induction of remission, death, and end-stage renal disease (ESRD). Fifty-two patients were registered, and 48 patients were enrolled in this study (mild form, n = 23; severe form, n = 23; most severe form, n = 2). Among the 47 patients who received the predefined therapies, 42 achieved remission within 6 months, 5 died, and 1 developed ESRD. Disease flared up in 8 of the 42 patients with remission during the 18-month follow-up period. The JMAAV trial is the first prospective trial for MPO-ANCA-associated vasculitis to be performed in Japan. The remission and death rates were comparable to those in several previous clinical trials performed in western counties. The regimen employed in this trial was tailor-made based on patients’ disease severity and disease type, and it seems that standardization can be consistent with treatment choices made according to severity

    Central nervous system post-transplant lymphoproliferative disorder after allogeneic hematopoietic stem cell transplantation: The Nagasaki transplant group experience

    Get PDF
    A 17-year-old male received allogeneic transplantation for acute lymphoblastic leukemia, and presented with generalized seizures due to a solitary brain lesion with massive necrosis on day +621. Epstein?Barr virus (EBV) DNA copies were below the cut-off value in plasma. Stereotactic biopsy of the cerebral lesion confirmed the diagnosis of post-transplant lymphoproliferative disorder (PTLD) with large atypical cells positive for CD20 and EBER.In order to diagnose primary central nervous system PTLD, the biopsy should be applied as early as possible when brain lesion with necrosis develops in post-transplant patients regardless of EBV-DNA in plasma

    Management of postoperative hemorrhage associated with factor VIII inhibitor: report of a case

    Get PDF
    This report presents a case that was successfully treated for acquired factor VIII inhibitor after extensive visceral surgery. A 71-year-old male who underwent surgery for bile duct cancer had active bleeding in the abdominal drainage tube on postoperative day (POD) 5, and prolonged activated partial thromboplastin time (aPTT) was detected (83.1 s) on POD 7. An extensive coagulation work-up revealed factor VIII deficiency (1 %), and a diagnosis of an acquired factor VIII deficiency was established when a factor VIII inhibitor of 8 Bethesda units was demonstrated. The patient was treated with activated prothrombin complex concentrate (aPCCs) and bloody discharge was stopped within 3 days. Inhibitor elimination was started using prednisolone on POD 20; rituximab, was administered on POD 74 and 81. Factor VIII inhibitor had disappeared by POD 124, and factor VIII (72 %) and aPTT recovered to 45.9 s. This case report demonstrated the efficacy of aPCCs and rituximab in the treatment of acquired hemophilia associated with visceral surgery. © 2012 Springer
