Mobile edge computing is a technology that can prepare for a new era of cloud computing and compensate for shortcomings by processing data near the edge of the network where data is generated rather than centralized data processing. It is possible to realize a low-latency/high-speed computing service by locating computing power to the edge and analyzing data, rather than in a data center far from computing and processing data. In this article, we develop a virtual mobile edge computing testbed environment where the cloud and edge nodes divide computing tasks from mobile terminals using the EdgeCloudSim simulator. Performance of offloading techniques for distribution of computing tasks from mobile terminals between the central cloud and mobile edge computing nodes is evaluated and analyzed under the virtual mobile edge computing environment. By providing a virtual mobile edge computing environment and offloading capabilities, we intend to provide prior knowledge to industry engineers for building mobile edge computing nodes that collaborate with the cloud.

This study investigated the luxury supply chain management called 'See now, Buy now'. This has been a new way of controlling the supply and demand for luxury brands in the fashion industry since 2016. In this study, we explored the backgrounds and impacts of 'See now, Buy now' in the digital era. 'See now, Buy now' was launched by the fashion brand, Burberry in February 2016. It was the first luxury brand to showcase its entire collection using 'See now, Buy now' among the brands which showcase in Paris, Milan, New York, and London fashion weeks. That has not only caused many controversies in the fashion world but also generated followers. In this study, we analyzed 'See now, Buy now' in three aspects, economics, efficiency, and management strategy, and this was done through a literature survey on articles pertaining to 'See now, Buy now' and empirical surveys on Burberry's collections. Based on 'See now, Buy now', Burberry tried a new process of supply and sale. In the era of SNS, the spread of information is getting faster. The speed of SNS and changes in the fashion market combining IT and mobile technology are major changes faced by the fashion industry. 'See now, Buy now', a model of the new supply and demand in luxury fashion brands, should be noted as a new directional aspect for the future of the fashion industry. Since it was a relatively recent trend that started from the September show of Burberry in 2016, there was still a lack of academic discussion or prior research on this phenomenon. Therefore this study aimed to predict future directions by recognizing the importance of 'See now, Buy now' in the fashion industry. Also, based on this research, the significance of this study was to present a management strategy that applies 'See now, Buy now' to the future of the fashion industry in the digital era.

Since a smart phone became popular that leads mobile era, we've faced diverse life style changes. Particularly, a mobile messenger which changes communication method from voice and video call to text based multi media messenger, leads new gift-giving culture called mobile voucher gift-giving. Although many researches have validated diverse models about digital voucher, this research utilize the model which divide motivation of gift-giving from three theories: gift-giving motivation theory, technology acceptance model, and consumer value theory. The purpose of this research is not only validate the model but also grouping by giving frequency of samples and validate disparity among groups. In conclusion, there are three groups founded and shows difference motivations.

In the smart life era where the majority of economically active population uses mobile devices, smart devices have formed a new service market. In this study, we developed a shipyard quality management application using mobile devices such as smart phones and tablet PCs. For this purpose, the problems were derived through the analysis of the quality management work on shipyard and the considerations were extracted to build a smart work environment by analyzing the case studies of smart work in other industrial fields. Among the shipyard quality management work, functions thought to be highly utilized when converted to a mobile system has been developed as a mobile application. The application was developed by applying an object-oriented component-based development (ooCBD) methodology, and is expected to improve the user experience and the efficiency of quality management operations in shipyard.

The adoption of technology has always been of interest to academicians and practitioners of the field of Management Information System. This is so because without proper and adequate adoption, technology-no matter how beneficial or advanced it may be-will be of little value to users. Numerous researches, such as the researches of the Technology Acceptance Model (TAM) or the Unified Theory of Acceptance and Use of Technology (UTAUT), had been conducted to understand the human nature in association with the adoption or rejection of technologies that have bombarded the users. The coming of smart technologies (i.e., smart phones and devices), however, seems to have fundamentally changed the environment for adoption. The ubiquity combined with mobility of technology, especially when it comes to mobile apps, seem to make the old PC era of two-stage-pre and post-adoption models obsolete. A new model of adoption that identifies the determinants of technology acceptance and continuance is needed for the smart age. To this end, this paper undertakes an empirical study, by analyzing 229 users of Social Networking Service (SNS) mobile apps, to identify the role of user experience on the multi-stage adoption of technology, and provides results that User Experience (UX) plays the crucial role of bridging the separate stages of pre and post adoption of technologies. The paper concludes by providing practical implications of the new model as it relates to mobile apps and technologies, and recommendations for further studies to get a better understanding of technology adoption in the smart age.

The purpose of the research was to investigate the characteristics of technology users, their knowledge about the technology and whether that affected technology adoption, and, through the measurement utilitarian value as a mediator, to find out whether the behavior toward mobile payment technology adoption is considered most effective during the COVID-19 pandemic, especially at this research locus, Central Java Province, Indonesian Batik SME consumers. The research methodology was quantitative with data processing using Structural Equation Modeling (SEM) with the final sample of 294 respondents' answers. To the best of the researcher's knowledge, this was an initial attempt toward a holistic and integrative approach to explain the adoption of mobile payment in Indonesia with different consumer characteristics in each region of Indonesia and varying levels of knowledge about mobile payment applications. The results show that the utilitarian value as a mediating variable only affected the relationship between the characteristics of technology users and adoption behavior. The findings of this study suggest that the stronger the knowledge of technology users, the more influential the adoption behavior of the mobile payment technology for Indonesian Batik small-, and medium-sized enterprise (SME) consumers during the COVID-19 pandemic in the new normal era.
