Technical advances have led to the advent of new forms of visual material in conference settings – the most notable of them being PowerPoint presentations. Long gone are the days when hastily scribbled notes would be delivered to the booth at the last minute, which allowed conference interpreters little to no time to prepare for. Instead, they now enjoy access to elaborately prepared PowerPoint presentations delivered online in advance. However, interpreters are now faced with new issues as PowerPoint presentations tend to differ in both style and density, sometimes exposing the interpreter to too much information while at others providing next to no information should the presentation be mostly image rather than text-based. The purpose of this paper is to gain insight into the perception that interpreters hold of such PowerPoint presentations when it comes to preparing for a conference.

Background: Recently, gintonin and gintonin-enriched fraction (GEF) have been isolated from ginseng, a herbal medicine. Gintonin induces [Ca2+]i transition in cultured hippocampal neurons and stimulates acetylcholine release through LPA receptor activation. Oral administration of GEF is linked to hippocampus-dependent cognitive enhancement and other neuroprotective effects; however, effects of its long-term administration on hippocampal gene expression remains unknown. Here, we used next-generation sequence (NGS) analysis to examine changes in hippocampal gene expressions after long-term oral administration of GEF. Methods: C57BL/6 mice were divided into three groups: control group, GEF50 (GEF 50 mg/kg, p.o.), and GEF100 (GEF 100 mg/kg, p.o.). After 22 days, total RNA was extracted from mouse hippocampal tissues. NGS was used for gene expression profiling; quantitative-real-time PCR and western blot were performed to quantify the changes in specific genes and to confirm the protein expression levels in treatment groups. Results: NGS analysis screened a total of 23,282 genes, analyzing 11-related categories. We focused on the neurogenesis category, which includes four genes for candidate markers: choline acetyltransferase (ChAT) gene, β3-adrenergic receptor (Adrb3) gene, and corticotrophin-releasing hormone (Crh) gene, and tryptophan 2,3-dioxygenase (Tdo2) gene. Real-time PCR showed a marked overexpression of ChAT, Adrb3, and Crh genes, while reduced expression of Tdo2. Western blot analysis also confirmed increased ChAT and decreased Tdo2 protein levels. Conclusion: We found that GEF affects mouse hippocampal gene expressions, associated with memory, cognitive, anti-stress and anti-anxiety functions, and neurodegeneration at differential degree, that might explain the genetic bases of GEF-mediated neuroprotective effects.

본 논문에서는 SAR(Synthertic Aperture Radar) 시스템에 적합한 이중편하 하중 지지형 마이크로스트림 8$\times$4 배열 안테나를 설계, 제작하여, 그 측정 결과를 시뮬레이션 결과와 비교하였다. 안테나 설계 시 운용 주파수와 대역폭, polarization putity, -3 dB 빔 폭 등과 같은 전기적 특성뿐만 아니라, 구조적 안정성, 강도, 강성 등의 기계적 특성을 함께 고려하였다. 본 안테나는 SSFIP 형 구조에 허니콤과 Shielding plane을 첨가한 형태이며, 이중편파는 서로 수직으로 위치한 두 개의 dog-bone shape 슬롯으로 구현하였다. 각 실험 결과로부터 제안한 안테나 중심 주파수 5.3 GHz를 중심으로 약 80GHz 의 대역폭을 지니고, -20 dB 이하의 cross-polarization level, 약 40dB 정도의 포트간 고립도 특성을 타나내며 구조적으로도 안정됨을 알 수 있었다. A 8$\times$4 microstrip antenna array is designed at 5.3 GHz and its characteristics are investigated with respect to the application in dual polarized synthetic aperture radars. The design is focused on the achievement of a wide bandwidth, a high polarization purity, a low loss, a good isolation and some mechanical requirements suitable for the application. The antenna is fed by a -3 dB tapered feed network, and is composed of dual polarized SSFIP (Strip-Slot-Foam-Inverted Patch) elements with honeycomb and shielding plane. Simulation results for the antenna array are presented and compared with measurements. It is observed that the antenna shows a bandwidth of 80 MHz, a polarization isolation better than 20 dB, an isolation of 40 dB, and good mechanical characteristics.

웹의 성장으로 웹 애플리케이션의 규모와 복잡도 또한 크게 증가하였다. 이로 인해 웹 애플리케이션 개발에 대한 공학적인 접근법이 연구되고 있으나, 화면 요구를 표현하는 방법에 대한 연구는 부족하다. 또한 기존의 화면에 대한 모델은 설계에 치중하거나, 표기법에 표준화되어 있지 않다. 본 논문은 웹 어플리케이션에서 화면구성에 대한 고객의 요구를 표준 모델링 언어인 UML을 이용해 모델링하는 방법을 제시한다.
통신 안테나용 허니콤 샌드위치 구조물의 충격 손상에 관한 연구

The impact response and damage of CLAS panel was investigated experimentally. The facesheet material used was RO4003 woven-glass hydrocarbon/ceramic and the core material was Nomex honeycomb with a cell size of 3.2mm and a density of 96 kg/㎥. The shield plane used was RO4003 and 2024-T3 aluminum. Static indentation and impact test was conducted to characterize the type and extent of the damage observed in two CLAS panels, and the performance of antenna used in a wireless LAN system. Correlation of peak contact force, residual indentation and the delamination area shows impact damage of the panel with an aluminum shield plane is larger than that of the panel with RO4003 shield plane, although the former is more penetration resistant. The damage was observed by naked eye, ultrasonic inspection and cross sectioning. The shape and size of delamination was estimated by ultrasonic inspection, and the area of delamination linearly increases as impact energy increases. The performance of impact damaged antenna was estimated by measuring return loss and radiation pattern. It was revealed that the performance of antenna was related to the impact damage and there was a threshold that the performance of antenna fell as impact energy level changed. The threshold was between the impact energies of 1.5J and 1.75J.
