Despite the Hanoi Summit between Donald Trump and Kim Jong Un, there has been no positive sign that the North Korea nuclear problem is being resolved. To advance the denuclearization negotiations, a new approach to denuclearization must be considered, which needs to meet two objectives simultaneously: to relieve North Korea's concerns about its regime change and to practically eliminate its nuclear capability to fabricate additional nuclear weapons and refurbish existing nuclear weapons. The new approach should consider infrastructures that would be indispensable in implementing North Korea's denuclearization processes and stopping any attempt to proliferate North Korea's nuclear materials and technologies amid denuclearization. Accordingly, this paper proposes a new roadmap whose key concept is to first disable and, then, gradually but completely dismantle the lynchpin nuclear facilities within 10 years. Here, lynchpin facilities are defined as key facilities that are directly related to the production of nuclear materials or other materials used when fabricating and refurbishing the key components of nuclear weapons or which would have a fatal impact on maintaining North Korea's nuclear weapon program. Additionally, this roadmap addresses corresponding measures for denuclearization activities. This roadmap consists of three sub-periods: the lynchpin disablement period, verification and dismantling period, and manifest threat removal period. This paper also identifies and incorporates into the roadmap the supporting infrastructure and possible corresponding measures to accompany the denuclearization steps. [ABSTRACT FROM AUTHOR]

The article proposes a comprehensive multilateral approach for solving North Korea's nuclear issue. A survey of previous proposals regarding the nuclear fuel cycle is made. A proposal is also made, calling for nuclear workers to be redirected to civilian sectors in order to attain irreversible dismantling of its nuclear weapons program. In this way, nuclear energy demands will reportedly be met without the risk of nuclear proliferation.

The visual scanpaths of 73 patients with schizophrenia and 97 healthy controls were monitored as they viewed happy, sad, angry, fearful, disgusted and neutral faces for identifying facial expression. Compared to controls, patients with schizophrenia performed poorly on recognizing the facial emotions of anger, fear and disgust, and neutral faces. For the analysis of visual scanpaths to salient features of faces, the eye, nose, and mouth areas were confined using the limited-radius Voronoi tessellation method. Overall, patients with schizophrenia fixated less frequently, but they fixated longer on the salient features of faces than controls. Moreover, their first fixation on the salient features of faces was longer than that of the controls, and their fixations were longer for eyes than mouth for angry and neutral faces. These results suggest that the lack of facial emotion recognition in patients with schizophrenia may be due to their reduced attention to the salient features of faces (as indexed by fewer fixations) and their difficulty in interpreting those features (as reflected in longer duration). Interestingly, among the patients, the frequency of fixation on the salient features of faces was positively correlated with the accuracy of facial emotion identification, indicating that directing their attention to the salient features of faces could enhance their emotion recognition accuracy.
