본 논문은 "한한대사전"에 기재된 "사기 열전" 관련 어휘 가운데 드러나 보이는 5가지의 문제를 규정(옳게 바꿈)한 것이다. 필자는 크게 의미해석 오류수정, 의미해석 보충수정으로 나누어 설명하였다. 그 대강의 내용은 아래와 같다. 첫째, 의미해석 오류수정에서는 "가여", "교칙", "관채"의 풀이가 "한한대사전"에서 잘못 기재되어있음을 밝혔다. 독자로 하여금 혼돈을 일으키기 쉬운 그럴듯한 해석으로 본의를 상실한 한 경우가 대부분이었다. 각각은 "빌려 줌${\rightarrow}$주다", "정리함${\rightarrow}$옛 것을 제거하고 새롭게 꾸밈, 수식, 교정윤식(색)", "관찰하여 채택함. 살펴서 취함${\rightarrow}$(주의 깊게) 찾아보다, 물색하다"로 의미해석을 수정해 주어야 한다. 둘째, 의미해석 보충수정에서는 "효실", "심념"의 의미항목이 부족함을 언급하였다. 각각에 대하여 "실력을 드러내다", "깊은 시름에 잠기다"의 풀이를 보충해 주었다. 또한 국내외 학자들의 번역본을 비교해보면 다음과 같은 결론을 얻을 수 있다. "가여" 항목은 정범진의 풀이가 가장 정확했다. "교칙" 항목은 박일봉, 왕리기, 양종현 학지달의 풀이가 비교적 타당했다. "관채"항목은 박일봉과 왕리기의 번역이 적합했다. "효실" 항목에서는 김원중이 올바른 해석을 했으며, "심념" 항목은 왕중의 번역이 가장 이상적이라고 사료된다.

Recent advancements in network infrastructures provide increased opportunities to support data delivery over multiple paths. Compared with multi-homing scenario, overlay network is regarded as an effective way to construct multiple paths between end devices without any change on the underlying network. Exploiting multipath characteristics has been explored for TCP with multi-homing device, but the corresponding exploration with overlay network has not been studied in detail yet. Motivated by improving quality of experience (QoE) for reliable data delivery, we propose a multipath message transport protocol based on application level relay (MPMTP-AR). MPMTP-AR proposes mechanisms and algorithms to support basic operations of multipath transmission. Dynamic feedback provides a foundation to distribute reasonable load to each path. Common source decrease (CSD) takes the load weight of the path with congestion into consideration to adjust congestion window. MPMTP-AR uses two-level sending buffer to ensure independence between paths and utilizes two-level receiving buffer to improve queuing performance. Finally, the MPMTP-AR is implemented on the Linux platform and evaluated by comprehensive experiments.

The effect of band-to-band tunneling (BTBT) leads to an obvious increase of the leakage current of junctionless (JL) transistors in the OFF state. In this paper, we propose an effective method to decline the influence of BTBT with the example of n-type double gate (DG) JL metal-oxide-semiconductor field-effect transistors (MOSFETs). The leakage current is restrained by changing the geometrical shape and the physical dimension of the gate of the device. The optimal design of the JL MOSFET is indicated for reducing the effect of BTBT through simulation and analysis.

The performance of large-scale cognitive radio (CR) networks with secondary users sustained by opportunistically harvesting radio-frequency (RF) energy from nearby primary transmissions is investigated. Using an advanced RF energy harvester, a secondary user is assumed to be able to collect ambient primary RF energy as long as it lies inside the harvesting zone of an active primary transmitter (PT). A variable power (VP) transmission mode is proposed, and an energy-based opportunistic spectrum access (OSA) strategy is considered, under which a secondary transmitter (ST) is allowed to transmit only if its harvested energy is larger than a predefined transmission threshold and it is outside the guard zones of all active PTs. The transmission probability of the STs is derived. The outage probabilities and the throughputs of the primary and the secondary networks, respectively, are characterized. Compared with prior work, the throughput can be increased by as much as 29%. The energy-based OSA strategy can be generally applied to a non-CR setup, where distributed power beacons (PBs) are deployed to power coexisting wireless signal transmitters (WSTs) in a wireless powered sensor network.

Descriptive statistics methods were used to study the spatiotemporal variations and sources of ambient particulate matter ($PM_{10}$) in Luzhou, China. The analyzed datasets were collected from four national air quality monitoring stations: Jiushi (S1), Xiaoshi (S2), Zhongshan (S3), Lantian (S4) over the period of 2003-2012. This city was subjected serious $PM_{10}$ pollution, and the long-term annual average $PM_{10}$ concentrations varied from 76 to $136{\mu}g/m^3$. The maximum concentration was more than 3-fold of the annual average ($40{\mu}g/m^3$) issued by EPA-China for the ambient air quality. General temporal pattern was characterized by high concentrations in winter and low concentrations in summer, and general spatial gradient was in the reduction order of S2 > S4 > S3 > S1, which were both due to different particulate contributors and special meteorological conditions. The source apportionment indicated that vehicular emissions, road dusts, coal burning and chemical dusts were the major contributors of the identified $PM_{10}$ pollution, and the vehicular emissions and the road wear re-suspended particles dominated the heavy $PM_{10}$ pollution in recent years. Two other potential sources, agricultural and celebration activities could decrease the air quality in a short term. Finally, some corresponding suggestions and measures were provided to improve the air quality.
