향나무류를 가해하는 향나무알락명나방(신칭)을 우리나라 미기록종으로 보고하며 성충 및 유충의 외부형태적 특징을 간략히 기술하였다. 금번조사를 통해 향나무, 누운향나무, 옥향나무 등 3종이 기주로 확인되었으며, 유충은 기주의 잎을 엮고 그 안에서 가해하는 것으로 조사되었다. A Phycitine species, Dioryctiria juniperella Yamanaka, is reported for the first time from Korea. Larval characters is also shown with its illustration. Juniperus chinensis L., J. chinensis var. globosa H., and J. procumbens S. are known as host plants for the species in this country.

Background and purpose: Octogenarians (age≥80 years) with coronary artery disease constitute a high-risk group. However, octogenarian patients with acute myocardial infarction (AMI) in the drug-eluting stents (DES) era have not been widely reported. We aimed to identify clinical outcomes in octogenarian compared with non-octogenarian AMI patients. Methods and subjects: We retrospectively analyzed 9877 patients who underwent percutaneous coronary intervention (PCI) with drug-eluting stents (DES) and who were enrolled in the Korean Acute Myocardial Infarction Registry (KAMIR). They were divided into 2 groups, octogenarians (n=1494) and non-octogenarians (n=8383), in order to compare the incidence of 1-year all-cause death and 1-year major adverse cardiac events (MACE), where MACE included all-cause death, recurrent myocardial infarction, target vessel revascularization (TVR), target lesion revascularization (TLR), and coronary artery bypass grafting (CABG). Results: The clinical status was significantly inferior in octogenarians compared to non-octogenarians: Killip class≥II (34.8% vs. 22.5%, p<0.001), multivessel disease (65.8% vs. 53.7%, p<0.001). Rates of 1-year all-cause death were significantly higher in octogenarians than in non-octogenarians (22.3% vs. 6.5%, p<0.001). However, the rates of 1-year recurrent myocardial infarction (1.3% vs. 0.9%, p=0.68), TLR (2.4% vs. 3.1%, p=0.69), TVR (3.6% vs. 4.3%, p=0.96), and CABG (0.9% vs. 0.9%, p=0.76) did not differ significantly between the 2 groups. Conclusions: Octogenarian AMI patients have higher rates of mortality and MACE even in the DES era. According to KAMIR subgroup analysis, the TLR/TVR rates in octogenarians were comparable to those in non-octogenarian AMI patients.
Family gauge boson production at the LHC
Koide, Y.,Yamanaka, M.,Yokoya, H. North-Holland Pub. Co 2015 Physics letters. Section B Vol.750 No.-
Family gauge boson production at the LHC is investigated according to a U(3) family gauge model with twisted family number assignment. In the model we study, a family gauge boson with the lowest mass, A<SUB>1</SUB><SUP>1</SUP>, interacts only with the first generation leptons and the third generation quarks. (The family numbers are assigned, for example, as (e<SUB>1</SUB>,e<SUB>2</SUB>,e<SUB>3</SUB>)=(e<SUP>-</SUP>,μ<SUP>-</SUP>,τ<SUP>-</SUP>) and (d<SUB>1</SUB>,d<SUB>2</SUB>,d<SUB>3</SUB>)=(b,d,s) [or (d<SUB>1</SUB>,d<SUB>2</SUB>,d<SUB>3</SUB>)=(b,s,d)].) In the model, the family gauge coupling constant is fixed by relating to the electroweak gauge coupling constant. Thus measurements of production cross sections and branching ratios of A<SUB>1</SUB><SUP>1</SUP> clearly confirm or rule out the model. We calculate the cross sections of inclusive A<SUB>1</SUB><SUP>1</SUP> production and bb@?(tt@?) associated A<SUB>1</SUB><SUP>1</SUP> production at s=14 TeV and 100 TeV. With the dielectron production cross section, we discuss the determination of diagonalizing matrix of quark mass matrix, U<SUB>u</SUB> and U<SUB>d</SUB>, respectively.

A unified picture for magnetism, superconductivity, quantum optics and other properties of molecule-based materials has been presented on the basis of effective model Hamiltonians, where necessary parameter values have been determined by the first principle calculations of cluster models and/or band models. These properties of the matetials are qualitatively discussed on the basis of the spin and pseudo-spin Hamiltonian models, where several quantum operators are expressed by spin variables under the two level approximation. As an example, ab initio broken-symmetry DFT calculations are performed for cyclic magnetic ring constructed of 34 hydrogen atoms in order to obtain effective exchange integrals in the spin Hamiltonian model. The natural orbital analysis of the DFT solution was performed to obtain symmetry-adapted molecular orbitals and their occupation numbers. Several chemical indices such as information entropy and unpaired electron density were calculated on the basis of the occupation numbers to elucidate the spin and pair correlations, and bonding characteristic (kinetic correlation) of this mesoscopic magnetic ring. Both classical and quantum effects for spin alignments and singlet spin-pair formations are discussed on the basis of the true spin Hamiltonian model in detail. Quantum effects are also discussed in the case of superconductivity, atom optics and quantum optics based on the pseudo spin Hamiltonian models. The coherent and squeezed states of spins, atoms and quantum field are discussed to obtain a unified picture for correlation, coherence and decoherence in future materials. Implications of theoretical results are examined in relation to recent experiments on molecule-based materials and molecular design of future molecular soft materials in the intersection area between molecular and biomolecular materials.
