  • We introduce a modified UV-imprint lithography, a resin transfer from the template to the substrate. We analyzed this method by considering the surface and interfacial free energies of the template-resinsubstrate system. This technique is purely fast and applicable to large area patterning.

  • Although blunt traumatic cardiac rupture is an uncommon injury, it can be associated with a high mortality rate. Two cases of cardiac rupture in blunt trauma patients are described herein. In those cases, applications of mechanical support devices such as ECMO (extracorporeal membrane oxygenation) and early surgery for exploration under cardiopulmonary bypass may be helpful for treating blunt chest trauma patients.

  • CO2 reforming of methane (CRM) based on Ni catalysts was studied using temperature programmed reaction (TPR). The onset temperature of the CRM reaction was increased in a repeated TPR experiments. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy showed formation of graphite structures on Ni during CRM reaction, which deactivate Ni-surfaces. Attempts were made for inhibiting deactivation of Ni surfaces and reducing onset-temperature of the CRM reaction by various surface modification techniques, which will be presented in this poster.

  • In this paper, utilizing a haptic display for 3D modeling practice is proposed. A haptic display called PHANTOM Omni providing 3D position as well as touch feeling is used to investigate how effectively the proposed practice works compared to the conventional ones for 3D modeling. Experimental results showed the proposed practice can provide positive effect for 3D modeling: improving the task completion time and lowering task workload, thus increasing the usability.

  • 본 논문에서는 기존에 구현한 유닉스 버전 CASE(Computer Aided Software Engineering) 도구인 OODesigner를 윈도 버전으로 이식한 연구 결과에 대하여 논한다. 유닉스 버전 OODesigner는 Rumbaugh가 제안한 OMT(Object Modeling Technique) 기법을 지원하기 위해 구현되었지만 윈도 버전은 UML(Unified Modeling Language)을 지원할 수 있도록 기능이 향상되었다. 본 논문은 구현된 윈도 버전 OODesigner의 설계 문서와 구현 결과를 제시하는 것을 목적으로 한다.

  • Me performed an experiment about preionization electron number density of charge transfer type KrF excimer laser. At the total pressure of 1.8 and 2.2 atm with helium (He) buffer gas, the experimental range of the electron number density is 8-9 ${\times}$ 10 cm The distance between electrode and preionization pin is 15 mJ at charging voltage of 27kV,gas pressure of 2.2 atm,gas mixture of F /Kr/He = 0.3/396.7(%).
