  • Neuromorphic hardware refers to brain-inspired computers or components that model an artificial neural network comprising densely connected parallel neurons and synapses. The major element in the widespread deployment of neural networks in embedded devices are efficient architecture for neuromorphic hardware with regard to performance, power consumption, and chip area. Spiking neural networks (SiNNs) are brain-inspired in which the communication among neurons is modeled in the form of spikes. Owing to brainlike operating modes, SNNs can be power efficient. However, issues still exist with research and actual application of SNNs. In this issue, we focus on the technology development cases and market trends of two typical tracks, which are listed above, from the point of view of artificial intelligence neuromorphic circuits and subsequently describe their future development prospects.

  • In recent years, a satellite navigation signal authentication technique has been introduced to determine the spoofing of commercial C/A code using the cross-correlation mode of GPS P(Y) code received at two receivers. This paper discusses the technical considerations in the implementation and application of authentication system simulator hardware to achieve the above technique. The configuration of the simulator consists of authentication system and user receiver. The synchronization of GPS signals received at two devices, data transmission and reception, and codeless correlation of P(Y) code were implemented. The simulation test result verified that spoofing detection using P(Y) codeless correlation could be achieved.

  • Today the company's brand sites are in tendency locating as a handy method to administrate company vision, value and image. So this study tried to examine the aspects of storytelling around Amore Pacific's brand site. To secure the discussion's centrality and concreteness, two issues are considered to be aimed in methodology. First, the menus of relevant site were examined to see if they are securing minimal narrative. This was an attempt to discuss the minimum narrativity that target text is supposed to possess, to objectify little more the term 'storytelling.' After considering the menus of relevant site through narratological ideas of Gerald Prince, the menus that satisfy the level of minimum narrative were hardly seen. Even 'OUR STORY', showing the intention of unraveling the vision and values within the company brand by stories, is not seemed to be reaching universal, objective storytelling. Second, pragmatic, reception theory were applied as another standard to judge storytelling possibilities of Amore Pacific's brand site. Roger C. Schank's script theory, being considered in the field of cognitive linguistics and cognitive psychology, became a handy tool for examining the interactions and its meaning between brand sites and its visitors. As a result, the relevant site could be seen as attempting storytelling following time sequence, through narrator kindly explaining 'visual image-event.' And it was conjecturable that, because of such function of narrator, visitors finishes storytelling in a personal shape by operating internal story based script. This study examined the level and methods of storytelling limited in online environment called as company brand site. But more studies are needed to be in progress, such as about the ways for company websites or brand sites to have an effective, continuous influence on potential consumers, narrator set-up ways suitable for character of subordinate menus, organizations of minimum narrative and so on.

  • 본 연구는 현재 시행되고 있는 BPO에 대해 제도적 차원에서 주요 쟁점으로 중심으로 신용장 제도와 비교하여 고찰하였다. BPO는 은행간의 약정이기 때문에 지급의무의 이행, 확인, 양도 등에 있어서 신용장제도와 차이를 보이며, 또한 유의해야 할 점이다. BPO은 기본적으로 기능 면에서 신용장과 유사하지만, 별개의 독립적인 제도로 운용되며 정보기술과 데이터를 기반으로 한다. 신용장을 포함한 전통적인 제도 보다는 더 효율적이며 비용 효과적이다. 따라서 전통적인 제도에 대한 전자적 대안으로 보여진다. 본 연구는 선행 연구를 중심으로 이미 발표된 BPO 관련 연구와 자료 등을 통하여 문헌 연구하였다.

  • 무역거래에 있어 화환신용장은 수입업자에 대한 신용도와 구매대금 지급의 보장기능으로 가장 많이 사용되는 결제수단이었다. 그러나 실무에서 절차상의 복잡성, 수익자가 개설은행에 대금지급을 청구하기 위해서는 신용장에 지정된 서류를 반드시 구비해야 하는데 요구되는 필수서류와 부가서류들의 준비과정과 비용 및 신용장 요구조건과의 일치에 상당한 복잡성이 존재해왔다. 이로 인해 대금결제과정의 시간적 비용적인 측면이 문제점으로 제기되어 왔다. 이러한 기존의 무역거래 절차상 지연 등에서 오는 문제점 등을 거래비용측면에서 전자신용장을 활용함으로써 개선하고자 하는 인식이 요구되는 것이다. 본 연구는 거래비용측면에서 발생할 수 있는 시간적 비용적인 측면을 극복할 수 있는 방안으로서 전자신용장을 활용하는 전략을 제시하는데 있다. 이를 위하여 기존 신용장과 전자신용장의 문제점 파악과 거래비용측면에서의 활용전략을 제시하고자 한다.
