This paper presents design and integration of the ROBHAZ-DT3, which is a newly developed mobile robot system with chained double-track mechanisms. A passive adaptation mechanism equipped between the front and rear body enables the ROBHAZ-DT3 to have good adaptability to uneven terrains including stairs. The passive adaptation mechanism reduces energy consumption when moving on uneven terrain as well as its simplicity in design and remote control, since no actuator is necessary for adaptation. Based on this novel mobile platform, a rescue version of the ROBHAZ-DT3 with appropriate sensors and a semi-autonomous mapping and localization algorithm is developed to participate in the RoboCup2004 US-Open: Urban Search and Rescue Competition. From the various experiments in the realistic rescue arena, we can verify that the ROBHAZ-DT3 is reliable in traveling rugged terrain and the proposed mapping and localization algorithm are effective in the unstructured environment with uneven ground. The another application is an military robot for an EOD(Explosive Ordnance Disposal) and reconnaissance mission. The military version of the ROBHAZ-DT3 with a water disrupter, a thermal scope and a long distance wireless communication device is developed and sent to the area of military tactics in Iraq. Consequently, the feasibility of the military version of ROBHAZ-DT3 is verified.

In this paper, design and integration of a newly developed double-tracked mobile robot called ROBHAZ-DT are introduced. It is designed to carry out military and civil missions in various hazardous environments such as the areas of fire, war, disaster and mine field etc. ROBHAZ-DT is configured with three mechanical bodies, namely front, rear and main body. By using its rotational passive adaptation mechanism equipped between the front and rear bodies, ROBHAZ-DT shows a good mobile capability on uneven terrain including stairs. The passive adaptation mechanism reduces energy consumption and offers simplicity in the design of the ROBHAZ-DT ...

Foldback intercoil (FBI) DNA is formed by the folding back at one point of a non-helical parallel track of double-stranded DNA at as sharp as $180^{\circ}$ and the intertwining of two double helixes within each other's major groove to form an intercoil with a diameter of 2.2 nm. FBI DNA has been suggested to mediate intra-molecular homologous recombination of a deletion and inversion. Inter-molecular homologous recombination, known as site-specific insertion, on the other hand, is mediated by the direct perpendicular approach of the FBI DNA tip, as the attP site, onto the target DNA, as the attB site. Transposition of DNA transposons involves the pairing of terminal inverted repeats and 5-7-bp tandem target duplication. FBI DNA configuration effectively explains simple as well as replicative transposition, along with the involvement of an enhancer element. The majority of diverse retrotransposable elements that employ a target site duplication mechanism is also suggested to follow the FBI DNA-mediated perpendicular insertion of the paired intercoil ends by non-homologous end-joining, together with gap filling. A genome-wide perspective of transposable elements in light of FBI DNA is discussed.

While studies have viewed the effect of Chinese talent-attracting programs launched by government since reform and open door policy, little of them has assessed these programs empirically and pertinently. This article intends to assess an important program - the Thousand Youth Talents Program (TYTP). Frist, this paper proposed a transnational migration matrix of the academics to clarify the dynamic mechanism of academic brain gain at the high end. Then, the Kaplan-Meier analysis and Cox regression model are used to empirically analyze the policy effect of TYTP. The results show that, academic ability have double edged impacts on brain gain at the high end, some scholars whose last employer's academic ranking is world's Top100 have stronger willing to return, and the negative effect of academic ranking decreases with time passing; while scholars with a tenure-track position, a tenure position or a permanent position tend to stay overseas, and the hazard rate of staying increases with age. The older scholars have more intentions to go back China, while gender was not a significant factor influencing academic return at the high end. That is, the talent-attracting programs has partly succeeded in bringing back the academics at the high end.

우리나라를 비롯하여 중국, 일본, 몽골, 러시아, 북한 등을 포함하는 동북아지역은 지리적으로 연접하고 있고 최근 급속한 산업화와 경제여건의 변화로 인해 월경성 환경오염 등 각종 환경문제가 발생하고 있으나 이를 조정, 관리할 시스템의 부재로 인해 효과적인 대처가 어려운 실정이다. 최근 관심이 높아진 유라시아 이니셔티브 및 북한과의 관계 개선 등과 관련하여 예상되는 향후 양자 및 다자간 개발사업 추진에 따른 동북아 월경성 환경영향평가에 대한 수요는 반드시 발생할 것으로 예상된다. 따라서 다양한 접근 방법을 고려하여 향후 인접국가와의 월경성 환경영향평가를 대비하는 작업이 반드시 필요하다고 할 수 있다. 이러한 배경아래 본 연구는 2004년 이래 환경부와 KEI를 통해 진행되어온 동북아 월경성 환경영향평가 사업에 대한 성과 분석과 월경성 환경영향평가 제도 관련 UNECE Espoo 협약의 구체적인 체계, 운영 및 사례 등을 통하여 최근 들어 관심이 집중되는 동북아 지역에서의 대규모 개발계획에 대한 월경성 환경영향평가 추진 전략에 대하여 제시하고자 한다. 주요 추진 전략으로는 관련 국가들의 동북아지역 월경성 환경영향평가제도 정착을 위한 지속적인 노력이 필요하며, 이와 함께 향후 예상되는 개발 사업들에 대한 양자간 또는 다자간 실무그룹을 구성하여 구체적인 가이드라인을 준비하는 것이 필요하다. 이를 위하여 양자간 또는 다자간 시범사업이 구체적인 추진전략의 첫 단계가 될 수 있을 것이다.
