The longstanding incompatibility between the two countries can be illuminated by drawing on three factors： the conflict of interest in the DPRK-ROK unification; the strategic interests of the nuclearization and the denuclearization-normalization dilemma; the Sino-U.S. dual power structure in Northeast Asia. In addressing these issues, this paper discusses the possibility of achieving diplomatic normalization between the U.S. and DPRK by examining in a comparative framework the feasibility of existing mechanisms. The paper concludes that unconventional mechanism is required to establish the initial momentum for a necessary political breakthrough, especially in light of the Trump phenomenon. Specifically, the author proposes a stepwise model to assist the diplomatic reconciliation and to further promote the restoration of peace, security and stability in Northeast Asia.展开更多

Crosslinked PU/PEGMA hybrid nanofibers were fabricated by a reactive electrospinning process with N,N＇-methylenebisacrylamide （MBAm） as erosslinker and benzophenone （BP） as photoinitiator. The photoinduced polymerization and crosslinking reaction took place simultane- ously during the electrospinning process. No significant difference in the membrane morphology was found by SEM when PEGMA content was less than 20 wt%. The crosslinked fibrous membranes of PU/PEGMA exhibit higher hydro- philicity and mechanical strength than PU membrane. These nanofibrous membranes are potential substitutes for artificial vascular scaffolds.展开更多
