With the major advancement of vehicle-related technologies and services, the demands for the in/out-vehicle service expansion increase significantly. The key importance of the service expansion is to provide various vehicle-centric services in addition to improve the convenience and usability of users with connectivity. Recently, Internet of Things (IoT) gains major attention for small device connectivity and service, and it widens its area to other industries including automotive to advance and diversify its services. In this paper, we investigated the technical direction of the IoT service with the analysis of IoT technologies in the perspective of the vehicle. At first, we analyzed the vehicle and IoT services in each so that we are able to suggest the service design guideline and consideration to release integrated services between vehicle and IoT. Also, we reviewed the cases of few vehicle and home IoT integration services for the major insights and future direction of the integration services.

Recently, public participation in government policy design has been further expanded and public services perceived by users are expanding. At this time, the role of the digital government and the direction of the service to be pursued are user-centered, and above all, it is necessary to focus on the keywords of pre-emptive, preventive, and customized. In order to propose service quality improvement in the public sector, service user-centered classification and monitoring are integrated and the usability of government documents is improved. It is necessary to identify the needs of whether to provide a path for public participation. In the post-corona era, people are accessing quarantine information from the digital government every day. The government should proactively respond to the acceleration of digital transformation and the non-face-to-face demands of the people who experience non-face-to-face daily life. In order to evolve into a smart organization along with the innovation promotion plan and to provide customized services, it is necessary to use existing guides for institutional and technical improvement, along with new technology and data-based analysis, to strive for change management. The government should seek counter-measures that have advanced one step ahead by incorporating new high-tech IT with user-centered necessary services. This study aims to derive improvement plans to provide user-centered digital government service design when designing public services and collecting public opinions. Based on the e-government development model research and the existing research on user-centered service design in the public sector, institutional and technical measures are provided for the improvement of digital government service design.

The main purpose of this research is to look into not only how users evaluate two major databases(BIST and SATURN) of the scientific and technical literature in Korea, but also what users expect from scientific and technical information services in general. The result of the user evaluation shows that there is a very little difference between two databases in database quality. It was found that BIST is better than SATURN in terms of accuracy, customer support, searching capability, and currency, whereas SATURN is preferred to BIST for completeness and the average number of retrieved items. User expectation for scientific and technical information is also investigated by surveying its user community. Among three user groups, there is notable disagreement in language uses to search non-korean literature. Each group also shows different demands for translation of original literature. This study attempted to evaluate the quality of the scientific and technical information (BIST and SATURN) and simultaneously to investigate users demands in general. By doing so, the specificity implied in quality evaluation of specific information services as well as the generalization of the users behaviors in scientific and technical community were accommodated in this study.

Product-service systems (PSS), integrating physical products and services, currently play a crucial role in sustainable economies. In addition to the highly competitive global economy, the emergence of new digital paradigms is supporting the shift toward servitization. Although the great potential of such paradigms is recognized by both practice and research, their implications for PSS are not yet clear. In particular, features of Internet of Things (IoT), such as total connectedness and ubiquity of smart sensors and actuators, provide various new opportunities for PSS. This study explores such opportunities by conducting structured literature review and 13 interviews. We organize the findings in two folds: First, we introduce four degrees of IoT involvement in PSS business models and elaborate the opportunities that they create for different types of PSS. Second, we present the key technologies and approaches that IoT provides concerning PSS lifecycle management.

In the past, organizations tended to focus on physical and technical aspects of managing corporate's information security (IS), rather than the aspect of human resources related to IS. Recently, increasing security incidents caused by organization members raise the issue of how to improve employees' compliance with security policies. This study conducted a field experiment to examine the effect of security awareness training and technical security services on employee's security behaviors. In Study 1, the number of spam opening cases were measured right after the IS training and re-measured three months later. In Study 2, a spam warning message was provided and then the number of employees' spam opening cases were counted to find out the effect of security services. It was found that both the IS training and the technical IS service were effective; they significantly decreased spam opening rates. However, the training effect did not last longer than three months. These findings suggest that organizations need to consider providing regular training programs and supplementary technical services to improve employees' compliance with security policies.

An open sharing market is a market providing a sharing business. It provides open sharing services handling various products, unlike existing sharing services providing specific products. Sharing under an open sharing market can include all products that are difficult for customers to deal with, and provides fluidity of trade through negotiating sharing periods and costs among sharers. There are many variant elements when you provide sharing services for various products. Therefore, in this paper, we propose an extensible architecture that can reflect the variant elements in open sharing markets. We expect the proposed architecture can continuously improve the extensibility of sharing services for various products, because we design sharing services as components to efficiently manage and provide various sharing services, and provide dynamic binding of variant elements.

So far, almost all IP media services are targeted to the specific devices, for example, IPTV services are mainly for TV, and social community services are mainly for PC etc.. This paper describes newly developed media service platform in which the high quality video services can be provided not only to the TV or PC but also to the PMP(Portable Media Player) and even to the mobile phone. The major technical issues of the service platform are synchronization of contents among the different devices and high quality TV grade video display in PMP device. We confirmed successful operation of multi-device converged services in the developed media platform. We also have a trial service plan in Gwangju city at the end of this year.
