Nagae Masahiro,Yoshio Tetsuo,Takada Jun,Hiraoka Yutaka,Takida Tomohiro 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1

Internally nitrided dilute W-Ti alloy specimens having a heavily deformed surface microstructure were prepared by a multi-step internal nitriding at 1573-2073 K. Primary nitriding below their recrystallization temperature induced a precipitation of ultrafine TiN particles. After secondary and tertiary nitriding, those precipitates grew into rod-like TiN with a length of 20-60 nm. The recrystallization temperature after nitriding was elevated above 2073 K. The yield strength at 1773 K obtained from nitrided W-0.5 mass% Ti alloy was about 5 times as large as that of the recrystallized specimen. DBTT of the nitrided alloys was about 373 K.

Association of direct bilirubin level with postoperative outcome in critically ill postoperative patients

Masaharu Nagae,Moritoki Egi,Kenta Kubota,Shohei Makino,Satoshi Mizobuchi 대한마취통증의학회 2018 Korean Journal of Anesthesiology Vol.71 No.1

Background: Hyperbilirubinemia is a common postoperative complication. Elevated direct bilirubin (D-Bil) and indirect bilirubin (I-Bil) levels are related to different pathophysiologies; therefore, their associations with outcomes also differ. However, there have been few comparative studies of such associations in postoperative patients. Methods: This retrospective study compared the associations of postoperative D-Bil and I-Bil with outcomes. We included adult patients requiring postoperative intensive care for more than 48 hours between 2008 and 2013, except those undergoing liver operations. The number of patients was determined using a power calculation. D-Bil and I-Bil measurements were obtained on postoperative days (POD) 1 and 2. The primary outcome was defined as hospital mortality, with the number of ICU-free survival days (IFSD) at POD 28 as the secondary outcome. Results: The study population consisted of 1,903 patients with a mortality rate of 2.2%. D-Bil at POD 1 was significantly higher in non-survivors than survivors (P = 0.001), but I-Bil at POD 1 showed no such relation (P = 0.209). Multivariate logistic analysis indicated that higher postoperative D-Bil was independently associated with increased postoperative mortality (POD 1: adjusted odds ratio [OR] = 2.32, P < 0.001; POD 2: adjusted OR = 1.95, P < 0.001), but I-Bil showed no such relation (POD 1: P = 0.913; POD 2: P = 0.209). Increased D-Bil was independently associated with decreased IFSD at POD 28 (POD 1: adjusted coefficient = –1.54, P < 0.001; POD 2: –1.84, P < 0.001). In contrast, increased I-Bil at POD 1 was independently associated with increased IFSD at POD 28 (POD 1: adjusted coefficient = +0.39, P = 0.021; POD 2: +0.33, P = 0.080). Conclusions: D-Bil indices have a higher capability than I-Bil for predicting poorer outcomes in critically ill postoperative patients.

Tomofumi Nagae 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.43 No.I

From Japanese scal year JFY01, which started on April 1, 2001, a new accelerator project to provide high-intensity proton beams proceeded into its construction phase. This project, which is now called the J-PARC (Japan Proton Accelerator Research Complex) project, is conducted under a cooperation of two institutions, KEK and JAERI. We set a goal to achieve 1 MW proton beams at 3 GeV and 0.75 MW beams at 50 GeV. The project will be completed within six years, with the anticipated rst beams in the spring of 2007. In this report, I describe the whole project, scientific goals of the project and strangeness nuclear physics programs in detail.

숭어의 생식주기를 밝히기 위해 2002년 2월부터 2003년 3월까지 제주도 동남부 연안에서 채집하였고, 난모세포의 발달과정을 조직학적 방법으로 관찰하였다. 난모세포의 발달과정은 GSI 변화와 밀접하였다. GSI는 9월에 급격히 증가하여 12월에 최고 값을 나타내었다. 난소의 조직학적 관찰결과, 염색인기와 주변인기의 난모세포는 연중 관찰되었으며, 8월에는 일부에서 난황을 포함하는 난모세포가 관찰되었다. 대부분의 난모세포가 10월과 12월에는 난황구기 단계의 난모세포로 발달했다. 10월과 12월에 난황구기 난모세포들을 가진 개체의 출현이 가장 높았으며, 잔존여포와 퇴화 난모세포는 2월부터 관찰되었다. 숭어의 주산란기는 11월에서 1월이고, 난군동기발달형의 난소를 가지며 외양으로 이동하여 산란하는 어류에 속한다.
