Recently because of development of technology the old cultural properties and damaged artworks are stored as digital information using digital technology and produced related contents as well as moving images or digital contents. The regenerated information and contents through digital technology conveys correct information of ancient art and helps audiences appreciate it, as well as it also stores accurate information and can be used for restoration and preservation of the work. In this study, the range of digital restoration was defined in three directions, and the exhibition of digital content with an ancillary role that can be useful the understanding of the heritage of nature and mankind using digital technology was defined as the range of digital restoration. In addition, the Ojukheon Museum in Kangneung and The Museum of Natural History in New York, which installed various digital displays to analyze and compare the types of digital display exhibitions used for digital restoration of the range, were described as examples. Through this, it was discovered that digital display exhibitions for digital restoration can effectively deliver information and stimulate participation and interest of visitors in the museums, which is able to be a positive way to preserve the heritage of nature and mankind.

Radio-Frequency Identification (RFID) or Near Field Communication (NFC) technology has many advantages over other visual interfaces since it does not require line-of-sight alignment, can identify multiple tags simultaneously, and does not destroy the integrity of original objects. In addition, smart devices such as smartphone and smartpad have NFC/RFID readers which can provide mobile and natural interactions with digital and physical contents. Augmented reality has an excellent visual interaction capability with digital contents in a real environment by embedding digital contents into the physical world. In this paper, we propose a new approach to digital content interactions using RFID/NFC-based tangible interfaces in augmented reality environments that utilize invisible interfaces in addition to marker-based visual interfaces. By combining the advantages of invisible and visual interfaces, more intuitive interactions with digital contents can be provided, which can remove the difficulty of using typical AR paddles that are widely used in AR interactions. In particular, a semantic AR ontology is defined to provide more convenient interactions. Through the semantic ontology-based inferencing, physical querying and filtering are effectively supported. We will show the effectiveness and advantage of the proposed approach by demonstrating implementation results.

Although digital contents markets grow very rapidly and are known as a higher value added industry, there is also potential risk in producing digital contents. Thus, many firms have begun to produce a firm's digital contents by outsourcing from other companies in order to catch-up new technologies and to make stable profits. However, since contracts are decided mostly based on bidding price and also standard contract are not available, there is a limit on the benefit from the contents outsourcing. Thus, this study argues that if both contract factors such as contract concreteness and flexibility are well managed, the on-line digital contents will increase the performance of a firm. This study deals with the influence on the firm's performance by the outsourcing in contract factors based on the empirical analysis. Using regression analysis with these two dependent variables, the findings showed that the contract concreteness had positive effects on both cost improvement performance and efficiency improvement performance, but the contract feasibility only had positive effect on efficiency improvement performance. In addition, the result of the study showed that the contract performance of outsourcing the digital contents have a positive impact on the partnership intention.

With the help of digital technology, contents production process has become flexible and transmedia situation has been in the rise. Transmedia contents is a new type of contents being based on the various media platform and establishes a consistent story world. They are newly appeared mode of contents in the age of digital convergence. Users reading and watching the several versions of story in the transmedia contents can create a comprehensive contents experience and deepen it. Developing their own aesthetics and meaning of media text, transmedia contents is changing the textuality of digital contents, contents production process and contents using behaviors and contexts.

In this study, we combine information hiding technique with digital contents protection scheme. For providing secure distribution on digital contents, a new paradigm can be proposed after considering both watermarking and fingerprinting techniques. In detail, publicly verifiable digital signature schemes are applied into digital contents. On signing digital copyrights, we can publicly verify its correctness if needed.

Numerous bio-digital contents have been produced by new technology using biochip and others for analyzing early chemical-induced genes. These contents have little meaning by themselves, and so they should be modified and extracted after consideration of biological meaning. These include genomics, transcriptomics, protenomics, metabolomics, which combined into omics. Omics tools could be applied into toxicology, forming a new field of toxicogenomics. It is possible that approach of toxicogenomics can estimate toxicity more quickly and accurately by analyzing gene/protein/metabolite profiles. These approaches should help not only to discover highly sensitive and predictive biomarkers but also to understand molecular mechanism(s) of toxicity, based on the development of analysing technology. Furthermore, it is important that bio-digital contents should be obtained from specific cells having biological events more than from whole cells. Taken together, many bio-digital contents should be analyzed by careful calculating algorism under well-designed experimental protocols, network analysis using computational algorism and related profound databases.

Recently, research on hologram, which can realize perfect 3-dimensional imaging, becomes more active. But hologram has the defect that it costs a lot in generation. Thus, this paper proposes a method to generate a new digital hologram contents by manipulating the existing digital hologram contents. That is, this paper proposes the method to manipulating the digital hologram contents by manipulating and/or synthesizing the depth information to get a new digital hologram contents. The proposed methods have been experimented with various depth informations and digital hologram contents. For each kind of depth information, it has been manipulated for its position and distance. The result was converted to a digital hologram by the computer-generated hologram method and the resulting hologram was reconstructed.

Technological development of information and communication have brought sharp changes to every sector such as society, culture, economy and education because of knowledge and information-oriented society. The number of classes has decreased, and some schools are closed or incorporated due to decrease of the population. Such phenomenon has brought changes to learning using digital technology and space. A change called digital innovation is characterized by interactive communication centering on the internet network. Therefore, it is very important to predict educational environment to be changed according to digital environment and to note how real learning space is changed. The development of digital technology in society in general presents two concepts of digital and contents, digitalized information. Such technology is recognized as a new paradigm in education sector and a new space is created through participation of instructors and learners in learning space. This study analysed cases of learning space of elementary schools based on bibliographical examination and related bibliography including data from academic presentations and news release to present developed leaning space. To present healthy and creative learning environment which can lead knowledge and information-based society in the future, the preface described the background, purpose, methods and range of the study, and analysed transitional processes of society and culture, digital learning contents, and learning space in education of elementary schools. Finally the study identified trends and cases of research on learning space and suggested digital learning contents space.
