Plasma Science and Technology 2013年第9期15卷 923-927页

作者： jee-hun KO Sooseok CHOI Hyun-Woo PARK Dong-Wha PARK Department of Chemical Engineering and Regional Innovation Center for Environmental Technology of Thermal Plasma (RIC-ETTP)INHA University253 Yonghyun-dongNam-guIncheon 402-751Republic of Korea Department of Environmental Chemistry and Engineering Tokyo Institute of Technology 4259-G1-22Nagatsuta-choMidori-kuYokohama 226-8502Japan

The low power arc plasma is characterized by extremely high enthalpy and temper- ature and it is easy to generate and control, and thus thermal decomposition process based on the plasma torch is receiving a great attention for decomposing non-degradable greenhouse gases. In order to elevate the economic feasibility, the effects of input power, waste gas flow rate and additive gases on the destruction and removal efficiency （DRE） of NF3 are examined. Specific energy density （SED） deceases as the flow rate increases, and accordingly, the DRE is reduced. The DRE is basically determined by the specific energy density. The highest DRE of NF3 was 97% for the waste gas flow rate of 100 L/min at a low input power level of 2 kW with the help of hydrogen additional gas. The inlet and outlet concentration of NF3 was analyzed using Fourier transform infrared spectroscopy （FT-IR） for DRE of NF3 evaluation. As a result, large amount of NF3 can be efficiently decomposed by low power arc plasma systems.

Varieties of research on turbulent-induced noise are conducted with combinations of acoustic analogy methods and computational fluid dynamic methods to analyse efficiently and accurately. Application of FW-H acoustic analogy without turbulent noise is the most popular method due to its calculation cost. In this paper, turbulent-induced noise is predicted using RANS turbulence model and permeable FW-H method. For simplicity, noise from 2D cylinder is examined using three different methods: direct method of RANS, FW-H method without turbulent noise and permeable FW-H method which can take into account of turbulent-induced noise. Turbulent noise was well predicted using permeable FW-H method with same computational cost of original FW-H method. Also, ability of permeable FW-H method to predict highly accurate turbulent-induced noise by applying adequate permeable surface is presented. The procedure to predict turbulent- induced noise using permeable FW-H is established and its usability is shown.

Radar Cross Section (RCS) is one of the most considerable parameters for ship stealth design. As modern ships are larger than their predecessors, RCS must be managed at each design stage for its reduction. For predicting RCS of ship, Radar Cross Section Analysis Program (RACSAN) based on Kirchhoff approximation in high frequency range has been developed. This program can present RCS including multi-bounce effect in exterior and interior structure by combination of geometric optics (GO) and physical optics (PO) methods, coating effect by using Fresnel reflection coefficient, and response time pattern for detected target. In this paper, RCS calculations of ship model with above effects are simulated by using this developed program and RCS results are discussed.

A Study on Transmission Loss Characteristics of Honeycomb Panel for Offshore Structures

引用

Journal of Applied Mathematics and Physics 2015年第2期3卷 172-176页

作者： Jae-Deok Jung Suk-Yoon Hong jee-hun Song Hyun-Woung Kwon Department of Naval Architecture and Ocean Engineering Seoul National University Seoul Republic of Korea Department of Naval Architecture and Ocean Engineering Chonnam National University Yeosu Republic of Korea Department of Naval Architecture and Ocean Engineering Koje College Koje Republic of Korea

Honeycomb panel is consisted of 3 layers that are double-faced sheets and honeycomb-shaped core. It is highly desirable for ship, railway, and aerospace industry. The reason is that honeycomb panel excels in strength and in its weight. However in terms of insulation, it is a little bit insufficient to commonly use sandwich-panel. In this paper, Moor’s theory is used to predict sound transmission loss (STL). The theory is assumed that core layer is homogeneous orthotropic. And to calculate STL, it is evaluated in terms of the symmetric and anti-symmetric panel impedances, and the characteristic impedance of air. After that predicted data are compared with experiment data.

Background: A phase II clinical trial of the comparison between eribulin plus gemcitabine (EG) and paclitaxel plus gemcitabine (PG) as first-line chemotherapy for patients with metastatic breast cancer (MBC) found that the EG regimen was less neurotoxic, but was similar in efficacy to the PG regimen. In the present study, we analyzed functional assessment of cancer therapy-taxane (FACT-Taxane) questionnaires from patients in this clinical trial to determine their quality of life (QoL). Methods: QoL was assessed using the Korean version of the FACT-Taxane questionnaires. After baseline assessment, QoL was assessed every 2 cycles for 12 cycles and every 3 cycles thereafter. The linear mixed model was used to evaluate the difference in QoL between the EG and PG arms. Results: Of the 118 enrolled patients, 117 responded to the FACT-Taxane questionnaires at baseline, 1 in the PG arm did not. Baseline QoL scores were not different between the EG and PG arms. During treatment, taxane subscale scores were significantly higher in the PG arm than in the EG arm after 2-13 cycles of chemotherapy (all P < 0.05), except for the 11th cycle. Neuropathy-specific analysis showed that patients in the PG arm had earlier and more severe neuropathic symptoms than those in the EG arm (P < 0.001). Conclusions: In our QoL analysis, the EG regimen delayed and decreased neuropathy as compared with the PG regimen. Therefore, eribulin would be a reasonable substitute for paclitaxel as first-line chemotherapy for MBC.

A schwannoma is a benign soft tissue tumor composed of Schwann cells. Clinically, the tumor is slow-growing and usually asymptomatic, rarely developing neurological symptoms. We present a case of a 44-year-old female who was diagnosed with an incomplete high radial nerve palsy, showing a wrist drop and extension of fingers due to schwannoma on the radial nerve of the upper arm. The patient showed excellent result after excision of the schwannoma and neurorrhaphy of the radial nerve.

背景与目的一项比较艾日布林联合吉西他滨(eribulin plus gemcitabine,EG)或紫杉醇联合吉西他滨(paclitaxel plus gemcitabine,PG)作为转移性乳腺癌(metastatic breast cancer,MBC)患者一线化疗方案的II期临床试验发现,EG方案的神经毒性较低,但疗效与PG方案相似。在本研究中,我们分析了该临床实验中的癌症患者生命质量测评量表–紫杉烷(functional assessment of cancer therapy-taxane,FACT-Taxane)问卷评分以确定他们的生活质量(quality of life,QoL)。方法使用韩国版的FACT-Taxane问卷评估QoL。在评估基线之后,前12个疗程中每2个疗程评估1次QoL,之后每3个疗程评估1次QoL。使用线性混合模型评估EG组和PG组QoL的差异。结果在118例入组患者中,117例在基线时回复了FACT-Taxane问卷,PG组中有1例患者没有回复。EG组和PG组之间的基线QoL评分没有差异。在治疗期间,除了第11个疗程外,在第2–13个化疗疗程后,PG组紫杉烷亚量表评分显著高于EG组(均P<0.05)。神经病变特异性分析显示PG组患者的神经病症状比EG组患者更早出现且更严重(P<0.001)。结论在我们的QoL分析中,与PG方案相比,EG方案延迟并减少神经病变的发生。因此,艾日布林是MBC一线化疗药物紫杉醇的合理替代品。
