The description of preserved resources is one of the requirements in digital preservation. The description is generally created in the format of metadata records, and those records are combined to generate information packages to support the process of digital preservation. However, current strategies or models of digital preservation may not generate information packages in efficient ways. To overcome these problems, this research proposed an internal structure of information packages in digital preservation. In order to construct the internal structure, this research analyzed existing metadata standards and cataloging rules such as Dublin Core, MARC, and FRBR to extract the core elements of resource description. The extracted elements were categorized according to their semantics and functions, which resulted in three categories of core elements. These categories and core elements were manifested by using RDF syntax in order to be substantially applied to combine metadata records in digital preservation. Although the internal structure is not intended to create metadata records, it is expected to provide an alternative approach to enable combining existing metadata records in the context of digital preservation in a more flexible way.

디지털 콘텐츠 식별체계인 UCI(Universal Content Identifier)는 디지털 콘텐츠의 투명한 유통과정과 효율적 검색과 관리를 위해서 만든 URN(Uniform Resource Name)에 기반을 둔 식별체계이다. UCI 식별자를 부여받은 디지털콘텐츠는 사용자가 원하는 콘텐츠를 정확하게 전달하기 위해서는 다양한 메타데이터 정보를 필요로 한다. 그러나 UCI에서 제공하는 식별 메타데이터만으로는 콘텐츠에 대한 다양한 정보를 표현하기에는 부족하며, 정보의 보다 정확한 표현과 효율적 검색 및 관리를 위해서는 UCI에서 제공하는 메타데이터와 함께 메타데이터 내에 표현된 개념과 그 의미 관계를 정형화하고 명시적인 방법으로 정의하는 온톨로지를 필요로 한다. 본 논문에서는 UCI 식별체계의 메타데이터간 개념관계를 온톨로지로 확장하고 도메인 온톨로지를 설계함으로써 구축된 UCI 메타데이터 정보를 효율적으로 이용하여 의미 기반의 검색과 관리를 가능하게 하였으며, 다양한 질의어를 통하여 메타데이터만을 이용하는 UCI식별체계에 비하여 효율적인 검색과 관리가 가능함을 보였다.

This study proposes web-based authoring system for the lecturers who published textbooks by inserting external open resource. When lecturer publishes textbooks, the system makes it easier to utilize external resources by providing an open resource pool that the lecturer can search not only his own resources but external resources. In addition, we designed an open resource pool based on Original Contents Tracing Model to check whether the scrapped resource is changed or not in the future. Open Resource Pool allows inserting text, images and videos by searching multimedia, and stores metadata for the follow-up management. We made the system to determine the change of the resource using the metadata stored in the tracking system. Through this research, we confirmed that it is possible to publish textbooks by utilizing a variety of open resources on the web and revise the book by tracing the scrapped resources.

Purpose - With the rapid development of information technology, the digital economy has become an important grip of the new development pattern, and the digital transformation of enterprises is a major trend. As SMEs are the mainstay of the economy and employment, it is important to study the digital transformation of SMEs to promote the development of the digital economy. Research design, data, and methodology - Based on a resource-based view, this report analyses the current situation and issues of digital transformation of SMEs from the perspective of digital orientation as well as the breadth and depth of technological capabilities of enterprises, using data from a survey of 200 manufacturing enterprises in China. Result - The results show that SMEs generally have a digital transformation mindset, but a weak digital foundation. In order to execute a digital strategy, companies need digital transformation capabilities. These behavioral capabilities are guided by the strategic direction of the business, and companies with strong capabilities are always trying to tap into the full digital potential. Conclusion - In order to effectively promote the digital transformation of SMEs, we suggest that SMEs pay attention to digital capability building, make good use of digital platforms and network resources, and lay a solid foundation for digital transformation; meanwhile, we suggest that government departments play a guiding and supporting role to build a cross-industry and cross-sector digital synergy system to help promote the development of SMEs' digital transformation. This paper presents some suggestions from both the internal and external environment of the enterprise, with the expectation of contributing to the digital transformation practices of SMEs.

Metadata schemas are well recognized as one of the important technological components for archiving and preservation of digital resources. However, a single standard is not enough to cover the whole lifecycle for archiving and preserving digital resources. This means that we need to appropriately select metadata standards and combine them to develop metadata schemas to cover the whole lifecycle of resources (or records). Creating a unified framework to understand the features of metadata standards is necessary in order to improve metadata interoperability that covers the whole resource lifecycle. In this study, the author approached this issue from the task-centric view of metadata, proposing a Task model as a framework and analyzing the feature of archival metadata standards. The proposed model provides a new scheme to create metadata element mappings and to make metadata interoperable. From this study, the author found out that no single metadata standard can cover the whole lifecycle and also that an in-depth analysis of mappings between metadata standards in accordance with the lifecycle stages is required. The author also discovered that most metadata standards are primarily resource-centric and the different tasks in the resource lifecycle are not reflected in the design of metadata standard data models.

The reference guide for the cost of establishing the digital documents has been used as a basis for establishing the budget for the construction of the knowledge information resource. However, due to the abolition of the nominal unit price notification in terms of IT projects, it is necessary to conduct research to convert the standard of the current labor force grade standard to the national incompetency standard (NCS). In this study, we investigate and revise the system and contents of the current knowledge information cost estimation model. In specific, i) we conducted gap analysis of cost estimation model and existing NCS model. As the contents conforming for the construction of the knowledge information resource were not adoptable, we define the description of the construction of the knowledge information resource and to identify the core elements of NCS prior to the improvement of the cost model. ⅱ) then we proposed improve the cost model considering integration with newly proposed NCS model for knowledge information construction job. In order to ensure the validity of the application of NCS development and cost estimation model, the experts reviewed relevant contents and made plans for improvement by using experts from supply and demand groups of various fields of national knowledge informatization projects.

In recent years, many computer systems that are used for patient diagnostic and treatment purpose s are being introduced within hospitals. Therefore, being in a position to manage the hospital entirely, efforts to integrate their own unique system into one have started. A system values humans and creates the surrounding atmosphere into one which maximizes the abilities of individuals. For this, a scientific integration management operation system is required. The type of system that is demanded due to this requirement is an ERP(Enterprise Resource Planning) system. Lately, even the hospital industry is beginning to show interest in efficient administrative methods. To deliver more predominant medical services, hospitals are trying to introduce scientific administrative methods, whose superiority were proven in enterprises, to the operation system of the hospital organization. ERP values humans over systems, and within a superior system, emphasizes the efficiency of the organization. This sort of process does not just evaluate and manage the working abilities of individuals, but provides an advanced working environment that increases the abilities of members within the organization by fold. Therefore, this research estimates through questionnaires and introductive cases how the introduction of ERP may change the work of customers within hospitals such as the radiologic technology department, and how it may also change the environment of medical services, thus striving to create a radiologic technology department that will not fall behind the times.
