C.-B. Moon,이춘식,M. Oshima,Y. Toh,J. Goto,Y. Hatsukawa,A. Kimura,M. Koizumi,A. Osa,T. Komatsubara,K. Miyakawa 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.4
The excited states of the doubly odd nucleus 118I have been studied by using in-beam γ-ray spectroscopy with the 110Cd(12C, p3n) reaction at Elab = 80 MeV. We have established several multi-quasiparticle states associated with different proton and neutron quasiparticle configurations. A I* = 14- level at 2561 keV was newly observed and found to be associated with the πh11/2υd5/2 configuration coupled to a pair of protons in the g7/2 orbital. TRS calculations for the 14- level indicated a favored oblate state based on the fully aligned four-quasiparticle π[h11=2(g7/2)2]23/2-υ[d5/2]5/2+ configuration. Another energetically favored state I* = 24- at 6216 keV could be interpreted as a noncollective oblate state from the fully aligned six-quasiparicle π[h11/2(g7/2)2]23/2-υ[d5/2(h11/2)2]25/2+ configuration. No Δ = 1 side band of the same parity as the πh11/2υh11/2 band was observed while a side band built on the πg9/2υh11/2 configuration was considered to be caused by the γ vibration coupling.
Electron Beam Coherency Determined from Interferograms of Carbon Nanotubes
조복래,C. Oshima 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.3
A field emission projection microscope was constructed to investigate the atomic and chemical-bonding structure of molecules using electron in-line holography. Fringes of carbon nanotube images were found to be interferograms equivalent to those created by the electron biprism in conventional electron microscopy. By exploiting carbon nanotubes as the filament of the electron biprism, we measured the transverse coherence length of the electron beam from tungsten field emitters. The measurements revealed that a partially coherent electron-beam was emitted from a finite area.

A SOI (Silicon On Insulator) structure with buried alumina was fabricated by ALD (Atomic Layer Deposition) followed by bonding and etchback process. The interface of alumina and silicon was analyzed by CV measurements and the cross section was investigated by SEM (Scanning Electron Microscope) analysis. The density of interface state of alumina and silicon was 2.5 1011 cmက2eVက1 after high temperature annealing for wafer bonding. It was conrmed that the surface silicon layer was completely isolated from the substrate by cross section SEM and AES (Auger Electron Spectroscope) depth prole. Moreover, XRD (X-ray Diraction) analysis was carried out to study the crystallization of the alumina layer before and after high temperature annealing. The alumina lm is slightly crystallized after annealing. The simulated results conrmed that the lattice temperature of MOSFET on SOI with buried alumina was lower than that of SOI with buried silicon dioxide. A device on this alumina SOI structure would have better thermal properties than one on conventional SOI, due to higher thermal conductivity of alumina than that of silicon dioxide.
Three-gene predictor of clinical outcome for gastric cancer patients treated with chemotherapy

<P>To identify transcriptional profiles predictive of the clinical benefit of cisplatin and fluorouracil (CF) chemotherapy to gastric cancer patients, endoscopic biopsy samples from 96 CF-treated metastatic gastric cancer patients were prospectively collected before therapy and analyzed using high-throughput transcriptional profiling and array comparative genomic hybridization. Transcriptional profiling identified 917 genes that are correlated with poor patient survival after CF at <I>P</I><0.05 (poor prognosis signature), in which protein synthesis and DNA replication/recombination/repair functional categories are enriched. A survival risk predictor was then constructed using genes, which are included in the <I>poor prognosis signature</I> and are contained within identified genomic amplicons. The combined expression of three genes—<I>MYC</I>, <I>EGFR</I> and <I>FGFR2</I>—was an independent predictor for overall survival of 27 CF-treated patients in the validation set (adjusted <I>P</I>=0.017), and also for survival of 40 chemotherapy-treated gastric cancer patients in a published data set (adjusted <I>P</I>=0.026). Thus, combined expression of <I>MYC</I>, <I>EGFR</I> and <I>FGFR2</I> is predictive of poor survival in CF-treated metastatic gastric cancer patients.</P>

Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the “2019 Seoul Consensus on Esophageal Achalasia Guidelines”) were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.
