In this paper, we designed a embedded system that will perform a primary role of Tangible Space implementation. This hardware includes function of image capture through camera interface, image process and sending off image information by LAN(local area network) or WLAN(wireless local area network). We define this hardware as a network based Visual Agent Platform for Tangible Space, This Visual Agent Platform includes the software that is RTLinux and CORBA

The purpose of this study is to analyze measures to promote a private finance initiative aimed at public facility regeneration in the midst of sharp increase in local financial burden due to the low birthrate and rapidly aging population. In particular, the study looked at the case of promoting a private finance initiative through a local platform aimed at public facility regeneration in Narashino, Japan. The study is based on the relevant systems and policies, and government documents and statistical data on the Narashino case. The results show that the local platform helps the local government and participants share business expertise and experiences, leading to improvements in their expertise and business capability. The local platform allows them to identify and discuss potential business ideas in advance, which in turn encourages private investment business.

Harmful contents on a mobile platform are becoming serious problems to young people due to the prevalence of smart phones with the fast development of mobile technology. Mobile applications and contents are so much optimized on the mobile environment that young men are exposed to many harmful contents. A system for blocking harmful contents is suggested in this study. The system includes a local proxy function, filtering module, and local database in order to increase the blocking efficiency. The local proxy function and the filtering module are implemented on an Android platform, and the local database are running on a PC-based server. The suggested system perfectly blocks harmful contents, and shows relatively high speed.

In this study, it was intended to explore a way to build a DB which links the resources and areas and regions already registered as cultural assets in connection with a project which is newly building local culture and arts resources. Towards this end, this study first identified the type and scale of existing local culture and arts resources that could be linked. Following which, to link the local cultural resources and collected cultural assets, this study investigated the websites such as the Cultural Heritage Administration's National Cultural Heritage Portal, municipal and provincial tangible cultural festivals, municipal and provincial intangible cultural assets, and Gyeonggi Memory. Furthermore, this study identified the amount of information sources to be built and the current status of each information source to identify detailed information sources. Finally, the metadata of local culture and arts resources were presented by classifying them into material and publication data metadata, document metadata, audiovisual metadata, oral recording metadata, village information metadata, and personal information village information metadata.

Recently, Intelligent Excavating System(IES) for earthwork automation is on progress since the end of 2006 as a part of construction technology innovation projects in Ministry of Land, Transport and Maritime Affairs. Task Planning System(TPS), one of the detail core technologies of IES, is an optimal work planning system in conditions of effectiveness, safety and economic efficiency by analyzing the work environment data based on earthwork design and work environment recognition technology. For effective earthwork planning, the location of platform must be the most optimal spot for minimization of time, maximization of productivity and reduction of overlapped work spaces and unnecessariness. Besides, the decision of optimal platform location is to be based on the specifications and then is able to be converted with the local area calculation algorithm. This study explains the decision of optimal platform location on the basis of local area from the work space separate process and judges the effectiveness.

Purpose: The purpose of this study is to investigate factors that affect overall attitudes on accommodations sharing platform businesses and effects of overall attitudes on sustainability of accommodation sharing platform and contribution to the tourism industry with the perspectives of millennials and generation Z. Research design, data and methodology: This study conducted an online survey. This study applied factor, ANOVA, and regression analysis to test hypotheses. Results: The results found that factors including economic, trust, environment, local market facilitation, and the quality of residents' life affect overall attitudes toward accommodation sharing, while social and experience aspects do now show significance on overall attitudes. Effects of overall attitudes on sustainability of the accommodation sharing platform and contribution to the tourism industry showed significance. Conclusions: The results provide managerial and policy implications. The results implied how millennials and generation Z perceive significant factors such as local market facilitation for economic benefits and environment aspects with usage of accommodation sharing support characteristics of millennials and generation Z. How to foster social aspects to interact with millennials and generation Z and experience aspects to enhance values of the accommodation sharing that shares experiences remained future issues for better development of sharing platform businesses.

In a traditional Single Sign-On (SSO) scheme, the user and the Service Providers (SPs) have given their trust to the Identity Provider (IdP) or Authentication Service Provider (ASP) for the authentication and correct assertion. However, we still need a better solution for the local/native true SSO to gain user confidence, whereby the trusted entity must play the role of the ASP between distinct SPs. This technical gap has been filled by Trusted Computing (TC), where the remote attestation approach introduced by the Trusted Computing Group (TCG) is to attest whether the remote platform integrity is indeed trusted or not. In this paper, we demonstrate a Trustworthy Mutual Attestation (TMutualA) protocol as a proof of concept implementation for a local true SSO using the Integrity Measurement Architecture (IMA) with the Trusted Platform Module (TPM). In our proposed protocol, firstly, the user and SP platform integrity are checked (i.e., hardware and software integrity state verification) before allowing access to a protected resource sited at the SP and releasing a user authentication token to the SP. We evaluated the performance of the proposed TMutualA protocol, in particular, the client and server attestation time and the round trip of the mutual attestation time.

The IoT industry is growing at a record growth rate every year, but developers face practical problems such as security, data storage, and heterogeneity between devices before developing an IoT platform. In particular, heterogeneity between devices occurs due to network type and protocol, and device firmware must be changed or multiple IoT platforms must be used in some cases. In addition, data is wasted due to redundant sensing due to the overflow of indiscriminate IoT devices. In this paper, we propose a device-independent firmware design to solve the heterogeneity between devices in the IoT platform environment where Local WAS uses the MQTT protocol.

According to the NGIS (National Geographic Information System) project conducted since 1995, the central and local government has been accumulating huge amount of geospatial data. Korean Ministry of Land, Infrastructure and Transport started its GeoSpatial open platform (V-World) service in January 2012, also offering a wide range of functions and services. However, the National GeoSpatial open platform is still woefully deficient for the users to find their desired data, lack of data for private business area, insufficient in publicity of local government and public-private partnerships. Through analyzing current research trend after GeoSpatial open platform served for three years, study on overseas expansion, system links, service improvement, utilization and future strategy has been mainly conducted. This study, by analyzing the advanced overseas GeoSpatial platform as well as domestic research trend and combining the concept of new technology, business platform and SMG (Seoul Metropolitan Government)'s GeoSpatial platform, proposes a policy for the construction of future GeoSpatial Open Platform model.
