[A Case of del(16)(q22) in a Patient with Acute Myeloid Leukemia with Complex Karyotype.]
Kim, Minki,Lee, Ji Won,Lee, Jin Kyung,Hong, Young Jun,Hong, Seok Il,Kang, Hye Jin,Cho, Eun Hae,Chang, Yoon Hwan 대한진단검사의학회 2010 Annals of Laboratory Medicine Vol.30 No.4
<P>Inversion of chromosome 16 [inv(16)(p13.1q22)] and t(16;16)(p13.1;q22) are associated with acute myelomonocytic leukemia (AMML) with eosinophilia and a favorable prognosis. On the other hand, patients with del(16)(q22) usually present with MDS or chronic myelomonocytic leukemia (CMML), which can evolve to AMML without eosinophilia, and this chromosomal aberration is associated with older age, a complex karyotype, and a poor prognosis. We report a case of AML with del(16)(q22) which showed a complex karyotype, absence of eosinophilia in bone marrow study and a poor response to chemotherapy.</P>

이 논문에서는 복합 적층판의 점진적 파손해석 기법을 개발하고 검증하였다. 강도 및 강성 예측의 정확성을 높이기 위해 재료 비선형 효과와 연속체 손상역학을 동시에 고려하였다. 파손 시작점과 성장을 예측하기 위한 식으로 Hashin의 판별식이 사용되었으며, 파손 모드는 수지인장/전단, 섬유 인장의 2가지 파손모드를 고려하였다. 비선형 탄성 및 점탄성의 구성방정식을 고려한 평형을 계산하기 위해 Newton-Raphson 방법이 사용되었다. 실험을 통해 얻어진 복합재료 단층의 물성을 이용하여 노치가 없는 시편에 인장력을 가했을 때 예상되는 적층복합재의 강도 및 변형률을 예측하였다. 이 경우 선형 물성과 저하계수만을 고려하여 예측된 강성/강도보다 실험결과에 근사하게 나타남을 확인하였다. This paper presents development and verification of the progressive failure analysis upon the composite laminates. Strength and stiffness of the fiber-reinforced composite are analyzed by property degradation approach with emphasis on the material nonlinearity and continuum damage mechanics (CDM). Longitudinal and transverse tensile modes derived from Hashin’s failure criterion are used to predict the thresholds for damage initiation and growth. The modified Newton-Raphson iterative procedure is implemented for determining nonlinear elastic and viscoelastic constitutive relations. Laminar properties of the composite are obtained by experiments. Prediction on the un-notched tensile (UNT) specimen is performed under the laminate level. Stress-strain curves and strength results are compared with the experimental measurement. It is concluded that the present nonlinear CDM approach is capable of predicting the strength and stiffness more accurately than the corresponding linear CDM one does.

To enable self-reliance activities of daily living (ADL) of patients with neuromuscular disorder, weight bearing orthosis (WBO) is prescribed to the patients. A passive WBO using elastic element such as rubber band and spring is the most widely used equipment for a daily living aids. The passive WBO use linkage structure to exert an assistive fore in the desired direction and this linkage structure is an important factor that determine the performance and usability of the WBO. If the mobility of the linkage is limited, the performance and comfortability of the WBO is reduced while the usability is reduced if the linkage structure become complex to increase mobility. To identify the design criteria to improve everyday usage of WBO, effect of the joint configuration of the WBO to its functionality and usability is analyzed. For the experiment, 10 ADL tasks are selected and the subjective usability and objective comfortability are measured by using visual analogue scale and pressure pad.
Enhanced thermal properties of graphene oxide-incorporated polymeric microspheres.
Kang, Minki,Bak, Hyeonseong,Yun, Young Soo,Jin, Hyoung-Joon American Scientific Publishers 2012 Journal of nanoscience and nanotechnology Vol.12 No.4
<P>Polystyrene (PS) microspheres coated with graphene oxide (GO) were prepared and the variation of their thermal properties according to the GO loading was examined. The GO content in the PS-GO nanocomposites was controlled by the GO dispersions at various concentrations. The GO was coated onto the surface of the PS microspheres through the strong ionic interaction between polyvinylpyrrolidone and the GO sheet. The thermal properties of the GO incorporated PS microspheres were affected by the GO, which disturbed the chain activity and exhibited effective heat shielding. It also delayed the permeation of oxygen and hindered the escape of volatile degradation products from the PS-GO nanocomposites. In addition, the thermal degradation temperature of the nanocomposites was increased above 15 degrees C and their T(g) was also increased above 4.0 degrees C. PS-GO exhibited higher thermal conductivity (0.173 W/mK) than that of pure PS (0.117 W/mK).</P>
