Social commerce, integration of social media and e-commerce, provides potential opportunities for consumers to talk about their ideas and exchange product-related information on online shopping platforms. Given the substantial prospects related to business opportunities and consumers' perceptions, this study explores the factors driving fulfillment of the psychological contract in social commerce platforms. This research proposes, examines, and proves a theoretical model for the post-purchase behavior of the consumers, through an empirical investigation of online questionnaire-based data, gathered from 367 consumers in a cross-sectional setting. Results show that the fulfillment of psychological contract, consumer loyalty, and affective commitment fully mediate the impact of consumer trust on platform and repurchase intention. The level of commitment toward the consumer by the platform is strongly related to the degree of consumer trust, which is reciprocated through re-purchase intentions. This study offers essential theoretical implications with regards to the social exchange theory, attribution theory, and an moderating effect of the platform empathy on consumers' trust-psychological contract fulfillment relationship. Likewise, this research has significant implications for practitioners and managers.

Network infrastructure has spread to an unprecedented extent and is used in various computing devices, such as smart appliances, smart phones, and embedded devices with sensors, which have all been appearing in the computing environment. To accommodate this trend, for a more intelligent service environment, the service platform needs to have abilities that facilitate the operation between services, dynamically share distributed computing resources, and manage appropriate contextual information. We have simulated a service platform to provide intelligent services using contextual information after having implemented the context management service. The context management service gathers raw contextual information from sensors and stores these in the context database. For a consistent basis of contextual information, time and location are used as the key values of the contextual information. The context management service also performs normalization to provide computable contextual information to context-aware applications. In this paper, a service platform based on Jini technology is proposed for constructing an interoperable, dynamic, and . intelligent service environment using contextual information.

The importance of a systematic approach to collect, process, analyze, and share safety data in aviation safety management is continuously increasing. Accordingly, the domestic aviation industry has been making efforts to build a Big-data platform that can utilize multi-field safety data generated and managed by various stakeholders and to develop safety management technology based on them. Big data platforms not only must meet appropriate technical requirements, but also need to establish a management system for effective operation. The purpose of this study is to suggest the requirements of the aviation safety big data platform operation procedure and plan by reviewing the advanced overseas cases (FAA ASIAS). This study can provide overall framework and managerial direction for the operation of the aviation safety big data platform.

Business ecosystem is becoming more inclined towards platform ecosystem, which attracts multi-side participants based on digital technology. The burgeoning interest in digital ecosystem leads to the rapid rise of research. In this paper, we suggest a research agenda, focusing on the benefits of complementors in platform ecosystem. First, we outline the extant papers on benefits from platform to participants from economic perspective, strategic management perspective, technology management perspective, and economic sociological perspective to provide comprehensive understanding about platform ecosystem. Second, we suggest systemic framework to provide integrative insights on the the topic of benefit from platform to complementors- (1) open innovation view, (2) economic performance view, and (3) sociological view. Specifically, we focus on empirical studies that investigate the relationship between the benefits from platform and spillover effects on complementors based on various dataset. In addition, by reviewing the past empirical research, we suggest future research agenda and implications for policy in platform ecosystem.

This paper, proposes an integrated management platform to solve various management issues for multicast environments, which have been considered as an important transfer method together the appearance of multipeer applications recently(i.e,. IPME). First of all this paper describes the problems and related works of multicast environments, and proposes the general architecture of a management platform to manage multicast environments after considering design requirements to implement a proposed platform. This paper also proposes the management services to be provided, a general system architecture, its functional modules, and the management architecture such as a management procedure, establishment phases, management policies, and a Management Information Base(MIB) structure. In order to verify the proposed IPME, it is also applied and implemented as prototyping system to the QoS management service for H.263 video encoding/decoding system, that is IPME-QoS, which currently is a critical issue and uses multicast environments.

In this paper, we introduce a big data platform and a metadata management technique for fishery science R & D information. The big data platform collects and integrates various types of fisheries science R & D information and suggests how to build it in the form of a data lake. In addition to existing data collected and accumulated in the field of fisheries science, we also propose to build a big data platform that supports diverse analysis by collecting unstructured big data such as satellite image data, research reports, and research data. Next, by collecting and managing metadata during data extraction, preprocessing and storage, systematic management of fisheries science big data is possible. By establishing metadata in a standard form along with the construction of a big data platform, it is meaningful to suggest a systematic and continuous big data management method throughout the data lifecycle such as data collection, storage, utilization and distribution.

This study is to find out the acceptance intention of international logistics platform which meet the needs of each other of shipper and international logistics company in the online. As you may know, the many korean traditional international logistics companies which have to compete with global logistics companies focused on economics of scale, have been in a big trouble. In this circumstances, though they should get used to the change to survive, they do not know what they try to overcome. So, I hope that this study would be helpful to them.

A reliability-based cost-benefit model for the risk management of oil platforms in the formulation of optimal decisions based on life-cycle consideration is proposed. The model is based on structural risk assessments and the integration of social issues and economics into the management decision process. Structural risks result from the platform's exposure to the random environmental loading associated with the offshore site where it is located. Several alternative designs of a typical platform are proposed and assessed from the cost-effectiveness viewpoint. This assessment is performed through the generation of cost/benefit relationships that are used, later on, to select the optimal design.

Network control platform (NCP) and quality of service switch (QSS) are developed to realize centralized control and management technology, which is essential for guaranteeing traffic engineering and service quality in the next generation network. This paper presents high-speed connection management mechanism to enhance connection setup delay of the existing SNMP interface between NCP and QSS. We built up a connection management platform in the laboratory environment to validate the realization of the proposed mechanism.

Integrated Urban Spatial Information Management Platform (USIMP) is defined as an operational environment where technologies for intelligent management of urban facilities are made possible through the integration of diverse technologies such as sensors for ground and underground facilities, middleware technology, wired and wireless network, GIS-USN linkage. To make the integration of these diverse technology possible, it is imperative to have a sound reference model for the platform. This paper provides a standardized reference model for USIMP based on the RM-OPD(Reference Model for Open Distributed Processing) standard.
