This paper presents a high-efficiency technique based on dielectrophoresis (DEP) for assembling metal, semiconductor, and polymer nanorods, which are synthesized by electrochemical deposition (ECD). The assembly patterns of these nanorods (width: 20 nm; length: 7 μm) were designed using a finite element method (FEM) simulation tool. Further, these nanorods were used in our experiment after their assembly patterns were fabricated. The assembly yield was found to be approximately 70% at an AC voltage of 30 Vp-p and at frequencies of 20 and 30 kHz, and the DC voltage prevented the random alignment of the nanorods at the edge of the assembly pattern. Moreover, the above-mentioned nanorods, which had different permittivities, were found to have similar assembly yields. The proposed method can be improved and applied to nanostructure device fabrication.

This work aims to implement expert and collaborative group recommendation services through an analysis of expertise and network relations NTIS. First of all, expertise database has been constructed by extracting keywords after indexing national R＆D information in Korea （human resources, project and outcome） and applying expertise calculation algorithm. In consideration of the characteristics of national R＆D information, weight values have been selected. Then, expertise points were calculated by applying weighted values. In addition, joint research and collaborative relations were implemented in a knowledge map format through network analysis using national R＆D information.

AIM To prove that tattooing using indocyanine green(ICG) is feasible in laparoscopic surgery for a colon *** From January 2012 to December 2016, all patients who underwent laparoscopic colonic surgery were retrospectively screened, and 1010 patients with colorectal neoplasms were included. Their lesions were tattooed with ICG the day before the operation. The tattooed group(TG) included 114 patients, and the non-tattooed group(NTG) was selected by propensity score matching of subjects based on age, sex, tumor staging, and operation method(n = 228). In total, 342 patients were enrolled. Between the groups, the changes in [Delta(Δ), preoperative-postoperative] the hemoglobin and albumin levels, operation time, hospital stay, oral ingestion period, transfusion, and perioperative complications were compared. RESULTS Preoperative TG had a shorter operation time(174.76 ± 51.6 min vs 192.63 ± 59.9 min, P < 0.01), hospital stay(9.55 ± 3.36 d vs 11.42 ± 8.23 d, P < 0.01), and postoperative oral ingestion period(1.58 ± 0.96 d vs 2.81 ± 1.90 d, P < 0.01). The Δ hemoglobin(0.78 ± 0.76 g/dL vs 2.2 ± 1.18 g/dL, P < 0.01) and Δ albumin(0.41 ± 0.44 g/dL vs 1.08 ± 0.39 g/dL, P < 0.01) levels were lower in the TG. On comparison of patients in the "N0" and "N1 or N2" groups, the N0 colon cancer group had a better operation time, length of hospital stay, oral ingestion period, Δ hemoglobin, and Δ albumin results than those of the N1 or N2 group. The operation methods affected the results, and laparoscopic anterior resection(LAR) showed similar results. However, for left and right hemicolectomy, both groups showed no difference in operation time or hospital *** Preoperative tattooing with ICG is useful for laparoscopic colectomy, especially in the N0 colon cancer group and LAR.

The design and fabrication processes of a novel scanner with minimized coupling motions for a high-speed atomic force microscope （AFM） were addressed. An appropriate design modification was proposed through the analyses of the dynamic characteristics of existing linear motion stages using a dynamic analysis program, Recurdyn. Because the scanning speed of each direction may differ, the linear motion stage for a high-speed scanner was designed to have different resonance frequencies for the modes, with one dominant displacement in the desired directions. This objective was achieved by using one-direction flexure mechanisms for each direction and mounting one stage for fast motion on the other stage for slow motion. This unsymmetrical configuration separated the frequencies of two vibration modes with one dominant displacement in each desired direction, and hence suppressed the coupling between motions in two directions. A pair of actuators was used for each axis to decrease the crosstalk between the two motions and give a sufficient force to actuate the slow motion stage, which carried the fast motion stage, A lossy material, such as grease, was inserted into the flexure hinge to suppress vibration problems that occurred when using an input triangular waveforrn. With these design modifications and the vibration suppression method, a novel scanner with a scanning speed greater than 20 Hz is achieved.

弄清明末耶稣会传教史上译名、礼仪争论发生的主要原因,一直是后代学者们关注的重点。现有的主要研究观点将利玛窦和龙华民之间的关系一分为二地对立了起来,把龙华民视为耶稣会在中国传教失败和阻碍东西方文化交流的负面人物。如果置身于耶稣会“传教神学—天学”的历史变迁过程中,就可以发现这种认识忽视了平民路线出现的真实背景和过程。本文将重点放在龙华民对利玛窦的继承性上,力图通过对被忽视的龙华民平民灵性传教路线进行分析和考察,还原出其中隐藏的历史真相和意义。在耶稣会内,接受了利玛窦遗命的龙华民不仅继承了利玛窦的知识传教,同时还非常重视福音的纯洁性,将维持自己摸索出来的传教路线与利玛窦路线之间的均衡作为核心工作。纵观龙华民的一生,可以说他是耶稣会灵修本土化即福音的完美道德和博爱主义的典范。
