Glyphosate is the active component of the top-selling herbicide, the phytotoxicity of which is due to its inhibition of the shikimic acid pathway. 5-Enolpyruvylshikimate-3-phosphate synthase (EPSPS) is a key enzyme in the shikimic acid pathway. Glyphosate tolerance in plants can be achieved by the expression of a glyphosate-insensitive aroA gene (EPSPS). In this study, we used a PCR-based two-step DNA synthesis method to synthesize a new aroA gene (aroAR. leguminosarum) from Rhizobium leguminosarum. In vitro glyphosate sensitivity assays showed that aroAR. leguminosarum is glyphosate tolerant. The new gene was then expressed in E. coli and key kinetic values of the purified enzyme were determined. Furthermore, we transformed the aroA gene into Arabidopsis thaliana by the floral dip method. Transgenic Arabidopsis with the aroAR. leguminosarum gene was obtained to prove its potential use in developing glyphosate-resistant crops.

Zircon is usually used as a main additive to silica-based ceramic core materials in precise investment casting in order toimprove their high temperature properties. But there is still a disagreement in its effect on crystallization behavior of fusedsilica. In this study, cristobalite crystallization of fused silica in three silica-based core materials containing 10, 30 and 50 wt%zircon respectively were investigated through X-ray diffraction (XRD) and scanning electron microscopy equipped with energydispersive spectrometer (SEM/EDS). Results showed that zircon addition had neglected effect on cristobalite crystallizationduring sintering at 1180 oC, 1200 oC, and 1220 oC, but could decrease crystallization during simulated casting process at1500 oC. It was suggested that diffusion of zirconium atoms played a crucial role in this suppressing behavior of zircon on thecristobalite crystallization. During cooling from 1500 oC, cristobalite transformation from β to α caused microcracks in thesesamples that containing 10% or 30% zircon. But when zircon content increased to 50%, crack was prevented. Less phasetransformation of fused silica → cristobalite and enhanced strength by zircon was supposed to be the reason that wasresponsible for prevented cracks.

이 연구는 인지적 방법으로서의 은유가 상업 광고에 어떻게 적용되는지를 탐구하는 것을 목적으로 하였다. 이를 위해 문자와 화보로 제작된 상업 광고를 분석하였으며 연구 방법으로는 질적연구와 분석적 연구를 사용하였다. 이 연구에서 은유의 세 가지 하위범주(구조적,방향적 및 존재론적 은유)의 적용을 분석함으로써 은유가 광고되고 있는 제품에 대한 수취인의 인식과 이해를 용이하게 하는 중요한 인지적 장치이며, 개념적은유는 영어 상업 광고에서 효과가 있을 뿐 아니라 설득이라는 큰 기능을 발휘한다는 것을 입증하였다. 또한, 영어 상업 광고에서 개념적은유의 기능과 중요성에 대해 탐구를 해 본 결과 은유가 비유적 표현일 뿐만 아니라 인간의 인지 활동에서 작동하는 인지 장치임을 알 수 있었다. 결론적으로 개념적 은유를 충분히 활용한다면 광고주들은 수취인의 구매 의도에 큰 영향을 미칠 수 있을 것으로 보인다. This study aims to explore how the metaphor as a cognitive method is applied in English commercial advertising. Both verbal and pictorial commercials are analyzed in this study, and qualitative as well as analytical methods are adopted in the interpretation. By analyzing the application of three subcategories of metaphor (structural, orientational, and ontological metaphor), it confirms that metaphor is not only an important cognitive mechanism that facilitates addressee’s awareness and understanding about the promoted products but the conceptual metaphor works in English commercial advertising and exerts great function of persuasion. (In other words, the advertisers can make full use of conceptual metaphor to impact the purchase intension) Moreover, the exploration of the function and significance of the conceptual metaphor in English commercial advertising testify to the statement that metaphor is not only a figurative speech but a cognitive mechanism working in human cognitive activities. The result shows that by making full use of conceptual metaphors, the advertisers can have a great effect on the purchase intension of adressee’s.

ObjectiveaaThe aim of this study was to find if systemic family therapy (SFT) does work in anxiety and depression with epilepsy in adolescents (ADAE). Methodsaa104 adolescents with epilepsy, aged 13–20 years old, were included from December 2009 to December 2010, the enrolled patients were with anxiety [Hamilton Anxiety Scale (HAMA) score ≥14 points] or depression [Hamilton Depression Scale (HAMD) score ≥20 points]. The patients were randomly divided into the control group (n=52) treated with antiepileptic drugs (AED) and the intervention group (n=52) undergone Systemic Family Therapy (SFT) as well as AED. The AED improvements, anxiety and depression scores, Social Support Rating Scale (SSRS), Family Assessment Device (FAD) and scale of systemic family dynamics (SSFD) were observed after 3-month treatment. ResultsaaThe frequencies of epileptic seizures in intervention group was decreased much more significantly than the control group (4.22±3.54 times/month vs. 6.20±5.86 times/month, p=0.04); and the scores of anxiety (9.52±6.28 points vs. 13.48±8.47 points, p=0.01) and depression (13.86±9.17 points vs. 18.89±8.73 points, p=0.02) were significantly decreased than the control group; meanwhile, the family dynamics and family functions were significantly improved, and the social support was also increased (p<0.05). ConclusionaaSFT combined with AEDs had better efficacies than AEDs alone, not only the frequency of epileptic seizures was decreased, but also the patients’ anxiety and depression were improved, and the family dynamics, family functions and social support were improved.
