The purpose of this study was to investigate the influence of retailing types on consumers' omnichannel experience while purchasing fashion products. The omnichannel experience occurs when retailers provide seamless customer experience across the various touchpoints of retail channels. In this empirical study, retail types were categorized into single-brand stores and multi-brand stores, and the relationship among store loyalty, brand loyalty, and customer retention was observed by the research model. A survey was conducted on the global consumers who had experience in purchasing fashion products via the omnichannel using Amazon Mechanical Turk; as a result, 351 responses were analyzed. The mediating and moderating effects of loyalty constructs and retail types were analyzed using Process Macro 4.0. The results indicated that a seamless omnichannel experience affects customer retention by mediating store loyalty and brand loyalty; additionally, the dual mediating effect of store loyalty and brand loyalty was significant. The moderating effect according to retail type was identified, and the moderated mediation effect of store loyalty was validated. The results showed that multi-branded retailers' store loyalty had a stronger influence on customer retention than that of single-brand retailers and exhibited the relationship between store loyalty and brand loyalty as well as retail types (single vs multi) in a seamless omnichannel customer experience.

Many retailers have extended their extant online channels (i.e., websites) to mobile channels for communicating with and delivering their products or services to customers. However, retailers have trouble delivering a cohesive and seamless customer experience across the Web and mobile channels. To address this challenge, we propose a way for retailers to enrich customers' seamless experiences across channels by configuring mobile channels (functionality- and interactivity-oriented configurations) along with traditional Web channels. This study theoretically contributes a research framework that posits the role of mobile channels as an extension of existing websites. It also provides practical insight for effectively articulating an e-commerce strategy in cross-channel electronic commerce.

In the last decade, the 2.4 GHz band of IEEE 802.11 WLANs has become heavily congested due to the explosive increase in demand of Wi-Fi connectivity. With the current deployment of enterprise WLANs, channel switching mechanism continues to exhibit inefficiencies because it cannot adapt to real-time channel condition and the inability to support seamless channel switching. Software Defined Networking (SDN) as an emerging architecture is promising to introduce flexibility and programmability for wireless network management. Leveraging SDN to existing enterprise WLANs, channel switching method can be improved significantly. This paper presents a software-defined enterprise WLAN framework with a load aware automatic channel switching solution, which utilizes AP load and channel interference factor (CIF) to provide seamless channel switching. Two automatic channel switching algorithms named Single Switch (SS) and Double Switch (DS) are proposed to improve the overall user experience and the experience of users with highest traffic load respectively. Experiment results demonstrate that our solution can efficiently improve user experience in terms of jitter, transmission delay and network throughout when compared to the conventional channel switching mechanism.

DASH(Dynamic Adaptive Streaming over HTTP) 기반 라이브 스트리밍 서비스의 품질을 향상시키기 위한 연구가 활발히 진행되고 있다. 그러나 기존 DASH 기반 스트리밍 기술들은 낮은 버퍼링 지연을 유지하면서 끊김 없는 재생을 제공하지 못하여, 라이브 스트리밍 서비스의 QoE(Quality of Experience)가 저하되는 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 QoE 기반의 세그먼트 스케줄링 기법을 제안한다. 제안하는 기법은 세그먼트 수신 시간과 변화량을 기반으로 세그먼트 요청시간을 적응적으로 스케줄링 한다. 시뮬레이션 결과를 통해 제안한 기법이 낮은 버퍼링 지연을 보장하고 버퍼 언더플로우를 적게 발생시켜 라이브 스트리밍 서비스의 QoE 향상을 확인하였다.

The Multi-access Edge Computing (MEC) paradigm equips network edge telecommunication infrastructure with cloud computing resources. It seeks to transform the edge into an IT services platform for hosting resource-intensive and delay-stringent services for mobile users, thereby significantly enhancing perceived service quality of experience. However, erratic user mobility impedes seamless service continuity as well as satisfying delay-stringent service requirements, especially as users roam farther away from the serving MEC resource, which deteriorates quality of experience. This work proposes a deep reinforcement learning based service mobility management approach for ensuring seamless migration of service instances along user mobility. The proposed approach focuses on the problem of selecting the optimal MEC resource to host services for high mobility users, thereby reducing service migration rejection rate and enhancing service availability. Efficacy of the proposed approach is confirmed through simulation experiments, where results show that on average, the proposed scheme reduces service delay by 8%, task computing time by 36%, and migration rejection rate by more than 90%, when comparing to a baseline scheme.

Creating a new retailing environment to meet the seamless experience requirements of consumers is a challenge for Omnichannel-related businesses. Based on the "appraisal-emotion-response" chain, the purpose of this research is to explore the psychological mechanism of omnichannel integration influencing customer retention and the moderating effect of customer showrooming experience. This research uses a structural equation model in partial least square software to analyze a two-stage survey (Study 1: n = 210; Study 2: n = 342) conducted in China. The results show that channel control experience has three dimensions: perceived channel attribute familiarity, channel type matching, and cross-channel access convenience; consistent interactive experience has two dimensions: information cross-channel consistency and cross-channel service support. Furthermore, both channel control experience and consistent interactive experience are favorable for customer retention through increased customer satisfaction (transactional and retailer satisfaction). Finally, customer showrooming experience positively moderates the relationship between consistent interactive experience and customer satisfaction. This research proposes a self-regulation process model to explain how omnichannel integration enhances consumers' experience, finally leading to consumer retention. The findings contribute to the omnichannel retail business literature and provide management implications for Asian retailers to implement an omnichannel business strategy.

In DC micro-grid system energy storage systems (ESS) are responsible for storing energy and balancing power. Also, control target of the bidirectional DC-DC converter(BDC) for ESS should be changed depending on the operating mode. During the grid connected mode, the BDC controls the battery current or voltage. When a grid fault occurs, the BDC should change the control target to regulate the DC-bus. The BDC with conventional control method may experience large transient state during the mode change. This paper proposes a control method of BDC for ESS. The proposed control method is able to provide autonomous and seamless mode transfer by a variable current limiter. To validate the proposed concept, simulation results using PSIM and experimental results from a 2kW prototype are provided.
