          日本の佛敎受容と排斥の說話

          ( Matsumoto ) 사단법인 한국교수불자연합회 2014 한국교수불자연합학회지 Vol.20 No.2

          본 론문은 『聖德太子傳曆』(이하 『傳曆』)에 있는 불교 수용과 배척 설화에 관한 고찰로, 불교 수용과 폐불 기사를 중심으로 『傳曆』이 가지는 특징을 日本書紀나 『補闕記』 와 비교하면서 검토했다. 이 두가지 문헌은『傳曆 』본문에도 선행 문헌으로 이름이 나오는 것이다. 여기서는 일부의 기사를 비 교한 뿐이지만, 『傳曆』 본문의 성립은 단순하게 이것들을 연결했다기보다 이것들을 참조하면서도 스스로의 시각에서 재구축 한 것이라고 말할 수 있을 것이다. 물론 성덕태자전으로서『補闕記 』에 가깝지만, 폐불 기사가 거 의 없는 『補闕記 』에 비해서 상당히 자세한 서술을 가지고 있다. 『曆錄 』등 현재 흩어 없어진 문언도 인용되어 있기 때문에 이것들이『傳曆 』만의 것인 지 판단이 어렵지만, 내용을 비교하면 어느 정도 독자적인 변경이 있다고 보 는 것이 타당하다고 생각된다. In this article, I explored narratives of reception and exclusion of Buddhism in “Syoutoku-Taishi Denryaku”. To discuss this problem, I compared “Syoutoku-Taishi Denryaku” with “Nihon shoki” and “Jougu Shoutokutaishi-den Hoketsuki”, both of which were quoted in “Syoutoku- Taishi Denryaku”. Although I only compared some articles here, I concluded that the descriptions of “Syoutoku-Taishi Denryaku” were written in its own point of view rather than reconstructed from previously written books. And “Syoutoku-Taishi Denryaku” has a detailed article about the exclusion of Buddhism for which “Jougu Shoutokutaishi-den Hoketsuki” has only a few words. It``s difficult to determine whether those articles were quoted from other books or written uniquely, because previously written books like “Ryakuroku”, whose articles were quoted in “Syoutoku-Taishi Denryaku”, has been lost. But an article about a war against Mononobeno Moriya in “Syoutoku-Taishi Denryaku” shows that it has modified its previous ones by itself.

          Evaluation of the Microvascular Research Center Training Program for Assessing Microsurgical Skills in Trainee Surgeons

          Seiji Komatsu,Kiyoshi Yamada,Shuji Yamashita,Narushi Sugiyama,Eijiro Tokuyama,Kumiko Matsumoto1,Ayumi Takara,Yoshihiro Kimata 대한성형외과학회 2013 Archives of Plastic Surgery Vol.40 No.3

          Background We established the Microvascular Research Center Training Program (MRCP)to help trainee surgeons acquire and develop microsurgical skills. Medical students were recruited to undergo the MRCP to assess the effectiveness of the MRCP for trainee surgeons. Methods Twenty-two medical students with no prior microsurgical experience, who completed the course from 2005 to 2012, were included. The MRCP comprises 5 stages of training,each with specific passing requirements. Stages 1 and 2 involve anastomosing silicone tubes and blood vessels of chicken carcasses, respectively, within 20 minutes. Stage 3 involves anastomosing the femoral artery and vein of live rats with a 1-day patency rate of >80%. Stage 4 requires replantation of free superficial inferior epigastric artery flaps in rats with a 7-day success rate of >80%. Stage 5 involves successful completion of one case of rat replantation/transplantation. We calculated the passing rate for each stage and recorded the number of anastomoses required to pass stages 3 and 4. Results The passing rates were 100% (22/22) for stages 1 and 2, 86.4% (19/22) for stage 3, 59.1% (13/22) for stage 4, and 55.0% (11/20) for stage 5. The number of anastomoses performed was 17.2±12.2 in stage 3 and 11.3±8.1 in stage 4. Conclusions Majority of the medical students who undertook the MRCP acquired basic microsurgical skills. Thus, we conclude that the MRCP is an effective microsurgery training program for trainee surgeons.

        • Aliphatic C−H Bond Activation Initiated by a (μ-η<sup>2</sup>:η<sup>2</sup>-Peroxo)dicopper(II) Complex in Comparison with Cumylperoxyl Radical

          Matsumoto, Takahiro,Ohkubo, Kei,Honda, Kaoru,Yazawa, Akiko,Furutachi, Hideki,Fujinami, Shuhei,Fukuzumi, Shunichi,Suzuki, Masatatsu American Chemical Society 2009 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.131 No.26

          <P>A (mu-eta(2):eta(2)-peroxo)dicopper(II) complex, [Cu(2)(H-L)(O(2))](2+) (1-O(2)), supported by the dinucleating ligand 1,3-bis[bis(6-methyl-2-pyridylmethyl)aminomethyl]benzene (H-L) is capable of initiating C-H bond activation of a variety of external aliphatic substrates (SH(n)): 10-methyl-9,10-dihydroacridine (AcrH(2)), 1,4-cyclohexadiene (1,4-CHD), 9,10-dihydroanthracene (9,10-DHA), fluorene, tetralin, toluene, and tetrahydrofuran (THF), which have C-H bond dissociation energies (BDEs) ranging from approximately 75 kcal mol(-1) for 1,4-CHD to approximately 92 kcal mol(-1) for THF. Oxidation of SH(n) afforded a variety of oxidation products, such as dehydrogenation products (SH((n-2))), hydroxylated and further-oxidized products (SH((n-1))OH and SH((n-2))=O), dimers formed by coupling between substrates (H((n-1))S-SH((n-1))) and between substrate and H-L (H-L-SH((n-1))). Kinetic studies of the oxidation of the substrates initiated by 1-O(2) in acetone at -70 degrees C revealed that there is a linear correlation between the logarithms of the rate constants for oxidation of the C-H bonds of the substrates and their BDEs, except for THF. The combination of this correlation and the relatively large deuterium kinetic isotope effects (KIEs), k(2)(H)/k(2)(D) (13 for 9,10-DHA, approximately > 29 for toluene, and approximately 34 for THF at -70 degrees C and approximately 9 for AcrH(2) at -94 degrees C) indicates that H-atom transfer (HAT) from SH(n) (SD(n)) is the rate-determining step. Kinetic studies of the oxidation of SH(n) by cumylperoxyl radical showed a correlation similar to that observed for 1-O(2), indicating that the reactivity of 1-O(2) is similar to that of cumylperoxyl radical. Thus, 1-O(2) is capable of initiating a wide range of oxidation reactions, including oxidation of aliphatic C-H bonds having BDEs from approximately 75 to approximately 92 kcal mol(-1), hydroxylation of the m-xylyl linker of H-L, and epoxidation of styrene (Matsumoto, T.; et al. J. Am. Chem. Soc. 2006, 128, 3874).</P>

        • Serum Periplakin as a Potential Biomarker for Urothelial Carcinoma of the Urinary Bladder

          Matsumoto, Kazumasa,Ikeda, Masaomi,Matsumoto, Toshihide,Nagashio, Ryo,Nishimori, Takanori,Tomonaga, Takeshi,Nomura, Fumio,Sato, Yuichi,Kitasato, Hidero,Iwamura, Masatsugu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

          The objectives of this study were to examine serum periplakin expression in patients with urothelial carcinoma of the urinary bladder and in normal controls, and to examine relationships with clinicopathological findings. Detection of serum periplakin was performed in 50 patients and 30 normal controls with anti-periplakin antibodies using the automatic dot blot system, and a micro-dot blot array with a 256 solid-pin system. Levels in patients with urothelial carcinoma of the urinary bladder were significantly lower than those in normal controls (0.31 and 5.68, respectively; p<0.0001). The area under the receiver-operator curve level for urothelial carcinoma of the urinary bladder was 0.845. The sensitivity and specificity, using a cut-off point of 4.045, were 83.7% and 73.3%, respectively. In addition, serum periplakin levels were significantly higher in patients with muscle-invasive cancer than in those with nonmuscle-invasive cancer (P = 0.03). In multivariate Cox proportional hazards regression analysis, none of the clinicopathological factors was associated with an increased risk for progression and cancer-specific survival. Examination of the serum periplakin level may play a role as a non-invasive diagnostic modality to aid urine cytology and cystoscopy.

          Magneto-Optical Properties of ZnMnSe-ZnSe-ZnCdSe Quantum Structures

          T. Kato and T. Matsumoto,M. Ito,M. Tajima,K. Omori,T. Muranaka,Y. Nabetani,T. Matsumoto 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.5

          We have studied the circularly polarized photoluminescence (PL) and reflectance properties of a series of ZnSe/ZnCdSe/ZnSe/ZnMnSe single quantum wells (SQWs) and ZnSe/ZnCdSe/ ZnSe/ZnCdMnSe /ZnSe coupled double quantum wells (DQWs). The degree of circular polarization of the exciton luminescence from the ZnCdSe non-magnetic semiconductor (NMS) well was studied as a function of the spacer layer thickness and the exciton energies in the NMS and the diluted magnetic semiconductor (DMS) regions. The polarization degree became larger as the spacer thickness became smaller. The polarization also depended on the excito n energies in the NMS and the DMS regions and became larger as the exciton energy in the nCdSe well became closer to that in the DMS layer or the DMS well.

          A Symmetrical Floating Impedance Scaling Circuit with Improved Low-frequency Characteristics

          MATSUMOTO, Fujihiko,NISHIOKA, Syuzo,MATSUO, Shota,OHBUCHI, Takeshi The Institute of Electronics and Information Engin 2017 IEIE Transactions on Smart Processing & Computing Vol.6 No.6

          Impedance scaling techniques are known as methods to realize large capacitance with a small capacitor. Recently, a symmetrical floating impedance scaling (SFIS) circuit was proposed. However, the circuit has restrictions on operations at a lower frequency. In this paper, improvement techniques for low-frequency characteristics of the SFIS circuit are proposed. In order to enhance the terminal resistance, a negative impedance converter (NIC) block is employed in the SFIS circuit. In addition, cascode transistors are introduced to enhance the internal resistance associated with a capacitor in the SFIS circuit. The proposed techniques make the pole frequency lower. The proposed SFIS circuit is applied to a third-order Chebyshev filter via simulation. Cutoff frequency fc of the filter is set to 100 Hz, and the passband ripple of the filter is set to 0.5 dB. Simulation results show that the filter employing the proposed SFIS circuit is superior to a conventional one.

        • Gemcitabine Plus Nedaplatin as Salvage Therapy is a Favorable Option for Patients with Progressive Metastatic Urothelial Carcinoma After Two Lines of Chemotherapy

          Matsumoto, Kazumasa,Mochizuki, Kohei,Hirayama, Takahiro,Ikeda, Masaomi,Nishi, Morihiro,Tabata, Ken-ichi,Okazaki, Miyoko,Fujita, Tetsuo,Taoka, Yoshinori,Iwamura, Masatsugu Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6

          This study was conducted to evaluate the effectiveness of a combination of gemcitabine and nedaplatin therapy among patients with metastatic urothelial carcinoma previously treated with two lines of chemotherapy. Between February 2009 and August 2013, 30 patients were treated with gemcitabine and paclitaxel as a second-line chemotherapy. All had received a first-line chemotherapy consisting of methotrexate, vinblastine, doxorubicin and cisplatin. Ten patients who had measurable histologically proven advanced or metastatic urothelial carcinoma of the urinary bladder and upper urinary tract received gemcitabine $1,000mg/m^2$ on days 1, 8 and 15 and nedaplatin $70mg/m^2$ on day 2 as a third-line chemotherapy. Tumors were assessed by imaging every two cycles. The median number of treatment cycles was 3.5. One patient had partial response and three had stable disease. The disease-control rate was 40%, the median overall survival was 8.8 months and the median progression-free survival was 5.0 months. The median overall survival times for the first-line and second-line therapies were 29.1 and 13.9 months, respectively. Among disease-controlled patients (n=4), median overall survival was 14.2 months. Myelosuppression was the most common toxicity. There were no therapy-related deaths. Gemcitabine and nedaplatin chemotherapy is a favorable third-line chemotherapeutic option for patients with metastatic urothelial carcinoma. Given the safety and benefit profile seen in this study, further prospective trials are warranted given the implications of our results with regard to strategic chemotherapy for patients with advanced or metastatic urothelial carcinoma.

          Note on the Codimension Two Splitting Problem

          Matsumoto, Yukio Department of Mathematics 2019 Kyungpook mathematical journal Vol.59 No.3

          Let W and V be manifolds of dimension m + 2, M a locally flat submanifold of V whose dimension is m. Let $f:W{\rightarrow}V$ be a homotopy equivalence. The problem we study in this paper is the following: When is f homotopic to another homotopy equivalence $g:W{\rightarrow}V$ such that g is transverse regular along M and such that $g{\mid}g^{-1}(M):g^{-1}(M){\rightarrow}M$ is a simple homotopy equivalence? $L{\acute{o}}pez$ de Medrano (1970) called this problem the weak h-regularity problem. We solve this problem applying the codimension two surgery theory developed by the author (1973). We will work in higher dimensions, assuming that $$m{\geq_-}5$$.
