본 연구는 최고경영자이론(Upper Echelon Theory)을 바탕으로 중국기업의 최고경영자팀(TMT) 특성이 국 제 인수합병 성과에 미치는 영향을 분석하였다. 본 연구는 2007년부터 2016년까지 완료된 중국 상장기업의 국제 인수합병 거래 259건을 대상으로 TMT의 과신, 정치적 연결, 해외경험 수준과 인수합병 성과 간의 관계를 분석하였다. 본 연구결과에 의하면, 중국기업 최고경영진의 과신은 국제 인수합병 성과에 부(-)의 영향을 미치는 것으로 나타났다. 또한 TMT의 정치적 연결은 국제 인수합병 성과에 정(+)의 영향을 미치는 것으로 나타났다. 그러나 TMT의 해외경험은 예상과 달리 국제 인수합병 성과에 영향을 미치지 않았다.

국가 사이의 문화거리가 다국적 기업의 성과에 영향을 미친다는 기존 연구에 기초 하여 본 연구에서는 문화거리로 야기되는 기업의 어려움이 최고경영진의 현지 대응 역량에 의해서 어떻게 완화되는지에 대한 연구 주제에 대해서 탐구하였다. 본 연구에서는 중국 시장에서의 현지 대응 역량은 1) 귀환자 여부 2) 교육 배경 3) 정치적인 연관성과 관련이 있음을 밝혔으며 이를 102개의 다국적 기업 데이터를 활용하여 실증적으로 분석하였다. 즉 이 연구는 다국적 기업 최고 경영진의 해외경험, 교육 수준, 그리고 정부 접근성이 중국이라는 시장에서 문화거리로 야기되는 단점을 상쇄하는 요소라는 사실을 검증하였다. 본 연구는 중국 시장을 넘어 다른 개발도상국에 진출한 외국계 기업의 현지 전략에도 실무적인 함의를 가질 것으로 기대한다.

The present study examined the effects of Korean white ginseng (WG, Panax ginseng C. A. Meyer) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The rats were administered with saline or WG (WG 100 or 300 mg/kg, p.o.) daily for 21 days. The cognitive improving efficacy of WG on the amnesic rats, which was induced by TMT, was investigated by assessing the Morris water maze test and by performing immunohistochemistries on choline acetyltransferase (ChAT), acetylcholinesterase (AchE), cAMP responsive element binding protein (CREB) and brain derived neurotrophic factor (BDNF). The rats treated with TMT injection (control group) showed impaired learning and memory of the tasks, but the rats treated with TMT injection and WG administration produced significant improvement of the escape latency to find the platform in the Morris water maze at the 2nd and 4th days compared to that of the control group. In the retention test, the WG 100 and WG 300 groups showed significantly increased crossing number around the platform compared to that of the control group (p < 0.001). Consistently with the behavioral data, result of immunohistochemistry analysis showed that WG 100 mg/kg significantly alleviated the loss of BDNF-ir neurons in the hippocampus compared to that of the control group (p < 0.01). Also, treatment with WG has a trend to be increased the cholinergic neurons in the hippocampal CA1 and CA3 areas as compared to that of the control group. These results suggest that WG may be useful for improving the cognitive function via regulation of neurotrophic activity.

Field performance and morphological characterization was conducted on seven transgenic lines of Codonopsis lanceolata expressing γ-TMT gene. The shoots were obtained from leaf explants after co-cultivation with Agrobacterium tume-faciens strain LBA 4404 harboring a binary vector pYBI 121 that carried genes encoding γ-Tocopherol methyltransferase gene (γ-TMT) and a neomycin phosphotransferase II gene (npt II) for kanamycin resistance. The transgenic plants were transferred to a green house for acclimation. Integration of T-DNA into the T0 and T1 generation of transgenic Codonopsis lanceolata genome was confirmed by the polymerase chain reaction and southern blot analysis. The progenies of transgenic plants showed phenotypic differences within the different lines and with relative to control plants. When grown in field, the transgenic plants in general exhibited increased fertility, significant improvement in the shoot weight, root weight, shoot height and rachis length with relation to the control plants. However, all seven independently derived transgenic lines produced normal flower with respect to its shape, size, color and seeds number at its maturity. Indicating that the addition of a selectable marker gene in the plant genome does not effect on seed germination and agronomic performance of transgenic Codonopsis lanceolata. T1 progenies of these plants were obtained and evaluated together with control plant in a field experiment. Overall, the agronomic performance of T1 progenies of transgenic Codonopsis lanceolata showed superior to that of the seed derived non-transgenic plant. In this study, we report on the morphological variation and agronomic performance of transgenic Codonopsis lanceolata developed by Agrobacterium transformation.
