Korea's port infrastructure is rapidly aging, with old port facilities with more than 30 years of public life expected to surge from about 23% in 2019 to 47% in 2029. Traditional, aging ports lose competitiveness in logistics processing, reducing development around the port and increasing human casualties due to the human resource-based maintenance of the facilities. Therefore, it is necessary to solve this problem by establishing systematic management technology based on a digital twin. This research aimed to present the specific implementation steps of a digital twin reflecting smart port technology through cases of port infrastructure disasters, aging status, and smart ports. The study analyzed the port infrastructure linkage system and created and mapped scenarios essential for digital twin implementation. Three-dimensional (3D) modeling and simulation data for disaster and aging management among existing port infrastructure systems were collected. A digital twin port was implemented with 3D modeling. It implements a port digital twin simulation that links data such as sensing data and image data acquired from the port infrastructure in real time. Implementing a digital twin port for port infrastructure disasters and aging management can secure predictive port infrastructure management and disaster safety

This study aims to collect and systematize indicators for each stage of digital transformation at the infrastructure level to accurately diagnose the current status of digital transformation in Korea and to serve as a reference for establishing a balanced digital strategy. In order to establish a framework for digital transformation of infrastructure, 19 indicators in three categories(tangible/intangible, data) were identified across three stages of digital transformation: computerization, digitization, and digital transformation, and 19 indicators in three categories were identified to study the changes in digital infrastructure. The main findings are: First, the digital transformation of infrastructure is at a high level, moving from digitization to digital transformation. Second, the scope of digital transformation policies is expanding as digital transformation is triggered, and additional policies on inclusion and social disparities should be prepared. It is also important to improve the regulatory environment, which is relatively undervalued. Third, as data becomes more important, it is important to develop indicators and measurements to strengthen digital competitiveness in terms of data infrastructure. This study is an exploratory study of the existing indicators, which can be used to conduct specialized research on the differences in the level of digital transformation by industry, sector, company size, age, gender, region, and group, and to study indicators for the expansion of digital transformation to social and industrial sectors. The expected effect is to deepen the process of understanding the interaction between each indicator, so that future digital transformation policies can be organized and promoted, and policy outcomes can be predicted and responded to in advance.

There are some problems on the system that uses a password comprising a digital signature to identify the secret key owner under the public key infrastructure. For example, the password can be difficult to remember or easy to be disclosure, and users should make more complex password to protect it. A number of studies have been proceeded in order to overcome these defects using the fingerprint identification technologies, but they need to change the current standard of public key infrastructure. On the suggested private key escrow system, the private key can be withdrawn only through the enrollment and identification of a fingerprint template after it is saved to a reliable third system. Therefore, this new private key escrow system can remove previous inconveniences of managingthe private key on current public key infrastructure, and it exhibited superior results in terms of the evaluation items when compared with the integrated method of the existing fingerprint identification and public key infrastructure.

From this year, KIGAM, one of Korean government-supported research institutes, has started new national program for digital geologic/natural resources infrastructure building. The goal of this program is to prepare digitally oriented infrastructure for practical digital database building, management, and public services of numerous types of paper maps related to geo-scientific resources or geologic thematic map sets: hydro-geologic map, applied geologic map, geo-chemical map, airborne radiometric/magnetic map, coal geologic map and off-shelf bathymetry map and so forth. As for digital infrastructure, several research issues in this topic are composed of: ISP (Information Strategy Planning), geo-framework modeling of each map set, pilot database building, cyber geo-mineral directory service system, and web based geologic information retrieval system upgrade which services Korean digital geologic maps scaled 1:50K. In this study, UML (Unified Modeling Language)-based data modeling of geo-data sets by and in KIGAM, among them, is mainly discussed, and its results are also presented in the viewpoint of digital geo-modeling ISP. It is expected this model is further progressed with the purpose of being a guidance or framework modeling for geologic thematic mapping and practical database building, as well as other types of national thematic map database building.

The digital photogrammetric products have been increasingly used as an accurate foundation for representing information associated with infrastructure management. The technological advances in merging raster and vector data within the framework of GIS have allowed for the inclusion of DTMs and digital orthophotos with vector data and its associated attributes. This study addresses not only generating DEMs and digital orthophotos but producing three dimensional building models from aerial photos of an urban area by employing the digital photogrammetric technology. DEMs and digital orthophotos were automatically generated through the process of orientations, image matching and so on, and then the practical problems, which must be solved especially in applying to urban areas, were considered. The accuracy of produced digital orthophotos was derived by using check points. Also three dimensional visualization imagery, which is useful in the landform analysis, and 3D building models were produced. Digital photogrammetric products would be used widely not only as GIS framework data layers by using the GIS link function which links attribute and image information in the database for applying to infrastructure management and but as geospatial data for especially 3D GIS in urban areas.

Unlike physical products, the distribution of digital content has involved many participants in all distribution phases from providers to consumers. The longer the distribution channel for services is, or the more participants that take part in it, the more the added value of the content increases. Consequently, the customer usefulness has been maximized. In order to enhance the values of digital content, it is utterly urgent to implement a service infrastructure that could be shared by all participants along the distribution path. Digital content is distributed from a creator to a final user through complex value chain stages. All the participants along the value chain exchange information about copyrights, marketing, and contents themselves, through the distribution channel. Recently, the more the distributed Information Technology environment has been widely used, the more the necessity of an identifier for digital content has been increased. In this paper, we examine the current status of the Korean distribution market of digital content, identify necessary distribution services of digital content, and establish a systematic roadmap to implement these services.

The Digitalia MUNI ARTS - a local node of the LINDAT/CLARIAH-CZ research infrastructure at the Faculty of Arts of Masaryk University constitutes a repository in the Islandora system. It is used for long-term preservation of research data together with their research environment in the form of digital platforms. We transfer the digital outputs of humanities scholars research to the repository according to a set plan, which is based on best practice recommendations for project management and digital curation. In this paper, we present how the results of interviews with platform developers and infrastructure stakeholders translate into the curation workflow, and a resulting model for migrating digital platforms to the repository. Reflecting on three types of problems we encountered during the implementation of platforms into the repository - communication problems, problems of external dependence, and management problems - we describe a modification of the migration process. We present six recommendations for repository administrators and curators in an academic setting - holding an introductory meeting with developers, researching significant and relevant theories of knowledge domain, consulting license experts, prioritizing requirements, and preparing handover protocol and progress reports.
