Based on density-functional theory calculations, we have examined the electronic structure of the conjugate honeycomb-chained-trimer model previously proposed for the Au/Si(111)-(p3×p3)R30˚ surface, For the optimized atomic structure, we calculate the surface band structure and simulate scanning-tunneling-microscopy (STM) images. The simulated STM images are compatible with the STM measurements, but the calculated surface band structure partly differs from angle-resolved photoelectron measurements. The present results indicate that a better model is required for the Au/Si(111)-(p3 × p3)R30˚ surface.

The road sign in dynamic traffic system is an important element which affects on human cognitive performance on driving. Web-based vision system simulator was developed to examine the cognition time of the road sign in dynamic environment. This experiment the cognition time of the road sign in dynamic environment. This experiment was designed in with-subject design with two factors: vehicle speed and the amount of information of the traffic sign. It measured the cognition time of the road sign through two evaluation methods: the subjective test with vision system simulator and computational cognitive model. In these two evaluations of human cognitive performance under the dynamic traffic environment, it demonstrated that subject's cognition time was affected by both the amount of information of traffic sign and driving speed.

본 논문에서는 전자상거래 시스템에서 효율적으로 운용될 수 있는 환불가능한 전자화폐 프로토콜을 제안한다. 전자화폐에서의 환불 가능성은 온라인 전자상거래의 특성상 필수적으로 요구되는 특징이며, 이러한 특징의제공시에도 사용자의 익명성 및 은행의 안전성이 확보되어야만 한다. 본 논문에서는 비밀 분산 스킴을 응용하여상점의 환불 기간 내에 전자화폐를 안전하게 환불할 수 있는 프로토콜을 제안하였으며, 이를 위하여 상점 초기화시 신뢰할 수 있는 기관의 비밀 분산 프로토콜과 환불 기간 이후 상인과 은행 사이에 이루어지는 이중사용 허가프로토콜을 추가하였다. 또한 제안된 프로토콜의 안전성, 익명성, 그리고 환불 가능성에 대한 증명을 제시하였다.

Purpose: There are some advantages of the acrylic resin denture base ; appropriate strength, volume safety, simple processing apparatus, and low cost. But, it have a weakness for fracture by intense pressure or shock. However, the repairs for resin denture base are possible using various materials and techniques. There is a few studies in repairs for resin denture base, but not clinical researches. And there is no studies in absorbed saliva into the region of fracture and bond strength. This study is to observe re-bond strength of resin denture base after repairing under saliva absorption. Methods: The samples were made of heat curing resin and the rectangular parallelepiped specimens which were 50mm long, 10mm wide and 3mm high. The four different groups immersed in the artificial saliva for 2 weeks were prepared, 1) no repaired control samples, 2) immediately repaired samples, 3) repaired samples after 1 day dry, and 4) repaired samples after 3 days dry. The prepared samples were repaired by two different curing materials, self curing resin and heat curing resin method. Each groups composed of 10 specimens were experimented with the three point bending tests for bonding strength measuring Results: There were under condition absorbed in the artificial saliva and repaired by self curing resin method, repaired specimens after 1 day and 3 days dry groups had higher values of bonding strengths than control group, and bonding strengths of immediately repaired samples were similar to those of control samples (p<0.05). There were under condition immersed in the artificial saliva and repaired by heat curing resin method, immediately repaired samples showed similar values to bonding strengths of control groups, and repaired samples after 1 day and 3 days dry groups were lower than those of control group (p>0.05). Conclusion: In this study, the repairs for resin denture base were remarkably high values of bonding strengths than those of the past, and showed that have stable bonding strengths independent of saliva absorption of denture base, so present repairs for resin denture base can be performed, regardless of saliva conditions.
