The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

Effect of Suction Nozzle Modification on the Performance and Aero-acoustic Noise of a Vacuum Cleaner
Cheol-Woo Park,Sang-Ik Lee,Sang-Joon Lee 대한기계학회 2004 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.18 No.9
The suction nozzle of a vacuum cleaner was modified to enhance the power performance and to reduce the airflow-induced acoustic noise. The suction power efficiencies of the vacuum cleaner were measured for various nozzles: (1) original nozzle, (2) original nozzle with modified trench height, (3) original nozzle with modified connecting chamber, and (4) a combination of (2) and (3). In addition, the suction pressure and sound pressure level around the suction nozzle were measured to validate the reduction of acoustic noise. The power efficiency and mean suction pressure increased when the trench height of the suction nozzle was increased. This was attributed to the suppression of the flow separation in the suction channel. Modification of the connecting chamber in the original nozzle, which had an abrupt contraction from a rectangular chamber into a circular pipe, into a smooth converging contraction substantially improved the suction flow into the connecting pipe. When both modifications were applied simultaneously, the resulting suction nozzle was more effective from the viewpoints of aerodynamic power increase and sound pressure level reduction.

<P>The order-order transition temperature (T(OOT)) in blends of poly(styrene-b-isoprene-b-styrene) (S-I-S) triblock copolymer and polyisoprene (PI) homopolymer was investigated by using synchrotron small-angle X-ray scattering (SAXS). Pure triblock copolymer undergoes an order-order transition (OOT) from hexagonally ordered cylinder (HEX) to body centered cubic (BCC) phases. In order to investigate the effect of the molecular weight of the added homopolymer on T(OOT) of the triblock copolymer, various low-molecular-weight PI homopolymers were studied. The results revealed that T(OOT) was affected by the PI molecular weight. T(OOT) was reduced for blends having low-molecular-weight PI.</P>
ENRICHED MESHFREE COLLOCATION METHOD FOR ELASTIC FRACTURE
Sang-Ho Lee,Young-Cheol Yoon,Myoung-Won Kim 한국산업응용수학회 2005 한국산업응용수학회 학술대회 논문집 Vol.- No.-
A meshfree collocation method with intrinsic enrichment for solving elastic crack problems is presented. A diffuse derivative approximation is applied in conjunction with an intrinsic enrichment of the near-tip asymptotic fields and a polynomial basis. These diffuse derivatives of the approximation do not require computing the derivative of the weight function or that of the moment matrix. The local behavior of the near-tip stresses is successfully captured so that the stress intensity factors can be accurately computed.
