we achieved high efficiency of GmPDS-silencing in various soybean germplasms including cultivated and wild soybeans. We also confirmed that VIGS occurred in the entire plant, including the root, stem, leaves, and flowers, and could transmit GmPDS to other soybean germplasms via mechanical inoculation. This optimized protocol using a SYCMV-based VIGS system in the soybean should provide a fast and effective method to elucidate gene functions and for use in large-scale screening experiments. -

There are an increasing number of outbreaks of human pathogens related to fresh produce. Thus, the growth of human pathogens on plants should be explored. Human pathogens can survive under the harsh environments in plants, and can adhere and actively invade plants. Plant-associated microbiota or insects contribute to the survival and transmission of enteric pathogens in plants. Human enteric pathogens also trigger plant innate immunity, but some pathogens?such as Salmonella?can overcome this... -

The Reed-Muller code is one of the efficient algorithms for multiple bit error correction, however, its high-computation requirement inherent in the decoding process prohibits its use in practical applications. To solve this problem, this paper proposes a graphics processing unit (GPU)-based parallel error control approach using Reed-Muller R(r, m) coding for real-time wireless communication systems. GPU offers a high-throughput parallel computing platform that can achieve the desired... -

언어교육 문제는 국제이해교육의 관점에서 접근할 필요가 있다. 세계화가 현상적 실제로 진행되고 있는 상황에서 서로 다른 언어로 의사소통해야하는 것은 당위적 현실이기도 하다. 한국의 새 정부가 제기한 영어교육 문제는 세계어의 습득, 국제이해교육, 그리고 교육의 관점에서 재해석될 필요가 있다. 한국에서 영어교육과 관련해서 가장 심각한 장애는 영어를 통해 전달된다고 믿는 외세에 대한 두려움증이다. 그러나 교육의 본질에 자유가 내재되어 있다는 본 논문의 가정을 전제로 할 때, 교육은 인종, 종교, 문화 등 그 어떤... -
세계화에 대한 대응: 국제화와 대학 환경의 급진적 변화
한국교육학회 교육학연구 2016, 54권 2호 12 341-372 (32 pages)
본 서울대학교 사례 연구는 세계화에 대응하기 위해 나타나는 대학의 국제화 노력과 급진적으로 변화하는 학교의 변화를 분석하였다. 분석 결과에 따르면, 최근 대학이 국제화를 표방하면서 경쟁, 효 율성, 수익성이라는 시장 개념이 대학의 교육 환경에 빠르게 침투하고 있음을 확인하였다. 이것은 대 학의 국제 경쟁력 강화를 위한 유학생 유치와 연구비 확보를 위한 전략을 통해 확인할 수 있다. 대학 에서 나타나는 국제화(internationalization)의 모습은 국제주의(internationalism)라기 보다는 세계교육 시장에서 경쟁력 강화를...
