The prominent advantages of Dual Material Surrounding Gate (DMSG) MOSFETs are higher speed, higher current drive, lower power consumption, enhanced short channel immunity and increased packing density, thus promising new opportunities for scaling and advanced design. In this Paper, we present Transconductance-to-drain current ratio and electric field distribution model for dual material surrounding gate (DMSGTs) MOSFETs. Transconductance-to-drain current ratio is a better criterion to access the performance of a device than the transconductance. This proposed model offers the basic designing guidance for dual material surrounding gate MOSFETs.

Tracking and exploiting instantaneous spectrum opportunities are fundamental challenges in opportunistic spectrum access (OSA) in presence of the bursty traffic of primary users and the limited spectrum sensing capability of secondary users. In order to take advantage of the history of spectrum sensing and access decisions, a sequential decision framework is widely used to design optimal policies. However, many existing schemes, based on a partially observed Markov decision process (POMDP) framework, reveal that optimal policies are non-stationary in nature which renders them difficult to calculate and implement. Therefore, this work pursues stationary OSA policies, which are thereby efficient yet low-complexity, while still incorporating many practical factors, such as spectrum sensing errors and a priori unknown statistical spectrum knowledge. First, with an approximation on channel evolution, OSA is formulated in a multi-armed bandit (MAB) framework. As a result, the optimal policy is specified by the wellknown Gittins index rule, where the channel with the largest Gittins index is always selected. Then, closed-form formulas are derived for the Gittins indices with tunable approximation, and the design of a reinforcement learning algorithm is presented for calculating the Gittins indices, depending on whether the Markovian channel parameters are available a priori or not. Finally, the superiority of the scheme is presented via extensive experiments compared to other existing schemes in terms of the quality of policies and optimality.

The instability of operational channels on cognitive radio networks (CRNs), which is due to the stochastic behavior of primary users (PUs), has increased the complexity of the design of the optimal routing criterion (ORC) in CRNs. The exploitation of available opportunities in CRNs, such as the channel diversity, as well as alternative routes provided by the intermediate nodes belonging to routes (internal backup routes) in the route-cost (or weight) determination, complicate the ORC design. In this paper, to cover the channel diversity, the CRN is modeled as a multigraph in which the weight of each edge is determined according to the behavior of PU senders and the protection of PU receivers. Then, an ORC for CRNs, which is referred to as the stability probability of communication between the source node and the destination node (SPC_SD), is proposed. SPC_SD, which is based on the obtained model, internal backup routes, and probability theory, calculates the precise probability of communication stability between the source and destination. The performance evaluation is conducted using simulations, and the results show that the end-to-end performance improved significantly.

In this paper, we present the performance evaluation of the reliable cooperative media access control (RCO-MAC) protocol, which has been proposed in [1] by us in order to enhance system throughput in bad wireless channel environments. The performance of this protocol is evaluated with computer simulation as well as mathematical analysis in this paper. The system throughput, two types of average delays, average channel access delay, and average system delay, which includes the queuing delay in the buffer, are used as performance metrics. In addition, two different traffic models are used for performance evaluation: The saturated traffic model for computing system throughput and average channel access delay, and the exponential data generation model for calculating average system delay. The numerical results show that the RCO-MAC protocol proposed by us provides over 20% more system throughput than the relay distributed coordination function (rDCF) scheme. The numerical results show that the RCO-MAC protocol provides a slightly higher average channel access delay over a greater number of source nodes than the rDCF. This is because a greater number of source nodes provide more opportunities for cooperative request to send (CRTS) frame collisions and because the value of the related retransmission timer is greater in the RCO-MAC protocol than in the rDCF protocol. The numerical results also confirm that the RCO-MAC protocol provides better average system delay over the whole gamut of the number of source nodes than the rDCF protocol.

본 논문은 오프라인 채널이 온라인 채널로 사업 영역을 확장할 경우 기존 오프라인 채널의 경쟁적 자산, 이를테면, 브랜드 명성, 서비스 만족도 등이 온라인 채널의 선호도로 연결될 수 있는지를 실증분석을 통해 증명하였다. 연구결과, 오프라인 채널의 브랜드 명성과 서비스 만족도가 오프라인 채널의 선호도에는 직접적으로 긍정적인 영향을 미치고, 온라인 채널의 선호도에는 간접적으로 영향을 미친다. 즉, 오프라인 채널의 경쟁력이 우수할 경우 고객 입장에서는 오프라인 채널의 선호도가 높아져서 거래관계에 대한 몰입과 충성심이 증가한 뒤, 시간적 거리를 두고 오프라인 기업이 확장한 온라인 채널에 대한 선호도 향상으로 발전해 갈 수 있음이 입증되었다. 즉, 오프라인 채널의 경쟁력 향상은 현재와 미래 모두의 사업 기회를 확보하는 데 긍정적 영향을 미치는 것이다. 본 연구의 주요 시사점을 정리하면 다음과 같다. 첫째, 유통 채널의 서비스 품질 관리가 브랜드 명성 관리보다 더욱 중요하다. 고객의 서비스에 대한 체험과 주관적인 평가는 장기적인 브랜드 명성 관리의 선행요소로서 중요할 뿐만 아니라, 채널 선호도에도 더 큰 영향을 미친다. 따라서, 신규 고객을 포함한 일반 고객을 대상으로 하는 광범위한 브랜드 포지셔닝 전략 보다는 기존 우수 고객을 대상으로 하는 서비스 만족도 향상 전략이 더 중요하다는 의미이다. 둘째, 기존의 오프라인 채널이 온라인 채널로서 인터넷쇼핑몰을 구축할 경우 기존의 오프라인 채널의 고객 선호도, 주관적인 평가가 그대로 온라인 채널에도 영향을 미친다는 점이다. 유통기관의 오프라인 채널이 온라인 채널로 확장한 경우뿐만 아니라, 기존의 전통 제조기업이나 서비스 기업이 영업활동의 확장으로서 온라인으로 채널을 확장한 경우도 마케팅 채널의 수직적 통합(Vertical Integration)으로서 유통채널의 확장에 준하여 모두 이에 해당될 수 있다. 셋째, '채널확장'이란 '기업이 자사의 마케팅 활동이나 영업활동의 채널을 증대하기 위하여 온라인 또는 오프라인으로 채널을 확대시키는 의사결정과 그 실행'을 의미하는 것임을 확인할 수 있다. 일반적으로 오프라인 기업의 온라인으로의 채널 확장은 유통채널 확장 그 자체를 위한 목적과 전반적인 경영 프로세스 혁신의 목적 두 가지로 나누어 질 수 있다. 전자는 전통 오프라인 기업의 매출액을 증대하여 수익창출에 기여하기 위함이고, 후자는 주로 오프라인 기업의 비용절감을 통해 수익증대에 기여하기 위함이다.

Graphene is only one atom thick planar sheet of sp2-bonded carbon atoms arranged in a honeycomb crystal lattice, which has flexible and transparent characteristics with extremely high mobility. These noteworthy properties of graphene have given various applicable opportunities as electrode and/or channel for various flexible devices via suitable physical and chemical modifications. In this work, for the development of all-graphene devices, we performed to synthesize alternately patterned structure of mono- and multi-layer graphene by using the patterned Ni film on Cu foil, having much different carbon solid solubilities. Depending on the process temperature, Ni film thickness, introducing occasion of methane and gas ratio of CH4/H2, the thickness and width of the multi-layer graphene were considerably changed, while the formation of monolayer graphene on just Cu foil was not seriously influenced. Based on the alternately patterned structure of mono- and multi-layer graphene as a channel and electrode, respectively, the flexible TFT (thin film transistor) on SiO2/Si substrate was fabricated by simple transfer and O2 plasma etching process, and the I-V characteristics were measured. As comparing the change of resistance for bending radius and the stability for a various number of repeated bending, we could confirm that multi-layer graphene electrode is better than Au/Ti electrode for flexible applications.

Nowadays, most companies seek after the greatest profit by means of offering the goods which consumers want timely and efficiently and minimizing the cost of inventory and distribution channel which amounts to the great portion of total cost. And according as EC(Electronic Commerce) market has increased rapidly, SCM(Supply Chain Management) for EC become one of the most important facts for companies, therefore this paper suggest SCM scheme which EC, especially B to C, is added to the existing commerce system. This paper uses internet for information integration of distribution channel which is away from one another and applies TOC(Theory of Constraint)'s DBR(Drum-Buffer-Rope) Scheduling for synchronization through the whole supply chain. It is possible to synchronize the whole supply chain by means of making the speed of manufacturing and distribution to be controlled by consumer's order which is received in distribution center, and inventory and loss of sales opportunities are minimized by constant. Buffer Management. If inventories in distribution center is short, then it needs to search CCR(Capacity Constraint Resource) in supply chain and to control the speed of manufacturing and distribution according to the ability of CCR. This paper applies PT(Partial Transshipment) strategy for Delivery from distribution center to store or cyber consumer. the strategy this paper suggests chooses neighbour area from area which each distribution center takes charge, and then makes product ordered by cyber consumer which lives in the chosen area to be delivered according to inventory of distribution center.

본 연구는 혁신적인 서비스전달채널의 수용과정을 설명하는데 있어, 기존의 수용관련 연구에서 논의되어온 수용대상에 대한 지각된 속성을 혜택, 비용 및 위험 차원에서 구성요인을 통합하여 각 요인이 수용의도에 미치는 직 간접적 영향관계를 살펴보고, 또한 기존 연구에서 간과되어왔던 이미 이용 중에 있는 기존채널에 대한 이용경험 요인이 기존채널과의 관계에 대한 장기지향성 즉, 지속적 이용의도의 형성과정 및 신규 서비스전달채널의 수용의도에 미치는 영향과정을 모형화하고 실증적 검증을 시도하고 있다. 연구결과, 기존 연구에서 주로 수행되었던 신규 수용대상의 특성에 대한 지각뿐만 아니라 사회교환이론에 기반한 기존채널에 대한 만족도와 대안적 채널의 매력도 등 과정적 변수로서 태도요인의 고려를 통해 상호작용적인 관점에서 수용행동의 결정과정을 설명하는 것이 타당함을 보여주었다. 통합된 구성개념으로서 수용채널의 특성에 대한 지각은 수용채널에 대한 매력도에 유의한 영향관계를 미치는 것으로 나타났으며, 과정적 태도변수로서 기존채널에 대한 만족도와 신규채널에 대한 매력도는 수용행동에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 실증결과를 바탕으로 다채널 이용 상황에서의 신규 서비스채널의 수용은 기존채널의 이용을 종결시키는 것이 아니기 때문에 신규채널의 수용을 기존 서비스채널의 이용경험과 대안의 매력도 등 다차원적 측면에서 고려하여야 할 것이고, 수용 후 확산에 대한 문제 또한 기존채널의 이용 연속선상에서 기존채널과 신규채널을 모두 고려해야 되는 등 통합적인 마케팅전략에 대한 관리적 시사점을 제시하였다.
