이 논문에서는 거칠기 돌기의 형상과 분포를 고려하는 CEB 모델에서 추가적으로 거칠기 돌기의 상호작용을 고려하는 모델에 대해 연구되었다. 이 모델에서는 탄성응착지수와 소성응착지수가 시뮬레이션을 하는데 있어 매우 중요한 인자이며, 응착 지수의 변화에 따른 무차원화 된 하중과 분리력을 분석하고 시뮬레이션 하였다. 시뮬레이션을 통해 상호작용을 고려했을 경우가 분리힘이 더 작아지는 경향을 보임을 확인했고, 거칠기 돌기의 상호작용이 응착 접촉에 있어 설정되어야 할 중요한 인자임을 확인했다. In this paper, CEB model considering interaction of asperity additionally were studied. In this model, elastic and plastic adhesion index was very important in deciding adhesive characteristics and varying elastic and plastic index, dimensionless load and pull-off force were analyzed and simulated. Through simulation, it was found that interaction of asperity also had very important influence on adhesive contact.

Because of the low melting temperature of solder, each temperature cycle initiates an irrecoverable creep deformation at the solder interconnection which connects the package body with the PCB. The crack starts and propagates from the position where the creep deformation is maximized. This work has tried to compare and analyze the thermal fatigue life of solder interconnection which is affected by the lead material, the size of die pad, chip thickness, and interface delamination of 48-Pin TSOP under the temperature cycle ($0^{\circ}C$~1$25^{\circ}C$). The crack initiation position and thermal fatigue life which are calculated by using FEA method are well matched with the results of experiments. The thermal Fatigue life of copper lead frame is extended around 3.6 times longer than that of alloy 42 lead frame. It is maximized when the chip size is matched with the length of the lead. It tends to be extended as the thickness of chip got thinner. As the interfacial delamination between die pad and EMC is increased, the thermal fatigue life tends to decrease in the beginning of delamination, and increase after the delamination grew after 45% of the length of die pad.

In this study, we do research in a proper microphone arrangement method by way of evaluating and analyzing the relation between an open angle of the microphones and a time difference of an input sound signal for an exact definition of a sound source. Then, We can expect that existing robots or machines with an only vision system will have more excellent environmental adaptation ability by supports of hearing sense.

Purpose: To evaluate the efficacy and safety of the ureteroscopic management of ureteral stones immediately after a first colic attack. Materials and Methods: We retrospectively analyzed the data of 226 patients with obstructive ureteral stones who underwent ureteroscopy with stone retrieval. The 67 patients in group A underwent ureteroscopy within 48 hours of admission to our emergency department, whereas the 159 patients in group B underwent ureteroscopy more than 48 hours after admission. The chi-square test was used to evaluate and compare stone-free status, auxiliary procedures, and complications and the Kruskal-Wallis and Fisher’s exact tests were used to analyze qualitative data. Results: Mean stone sizes in groups A and B were 2.41±1.62 mm and 4.11±2.64 mm, respectively. No patient experienced a major complication during or after the procedure. Stone-free rates were 89.55% and 89.93%, respectively. Conclusions: Emergency ureteroscopy in cases of obstructive ureteral stones is both safe and effective and offers the advantages of immediate stone fragmentation and the relief of acute-onset colic pain.
