Recently, deep learning technology has become those methods as de facto standards in the area of medical data representation. But, deep learning inherently requires a large amount of training data, which poses a challenge for its direct application in the medical field where acquiring large-scale data is not straightforward. Additionally, brain signal modalities also suffer from these problems owing to the high variability. Research has focused on designing deep neural network structures capable of effectively extracting spectro-spatio-temporal characteristics of brain signals, or employing self-supervised learning methods to pre-learn the neurophysiological features of brain signals. This paper analyzes methodologies used to handle small-scale data in emerging fields such as brain-computer interfaces and brain signal-based state prediction, presenting future directions for these technologies. At first, this paper examines deep neural network structures for representing brain signals, then analyzes self-supervised learning methodologies aimed at efficiently learning the characteristics of brain signals. Finally, the paper discusses key insights and future directions for deep learning-based brain signal analysis.

Although the Korean government is making great effort to prevent the redundancy in IT investment and efficiently allocate the IT budget, actual achievements are quite limited because of the variety of IT resources and different architecture description among organizations and projects. Thus, a standardized description model of the system architecture is strongly needed to identify the common resources and improve the efficiency of IT investment. Therefore, in this paper, we have developed the function-network matrix model which can be used as the basic template for a standard for architecture description of e-Government systems. The function-network matrix model integrates the function tiers and the network areas into a single unified framework, which enables the functionality of each component and the flow of information clearly visible. Moreover, we described the architectures of Korean e-government’s citizen service systems using our model, resulting in clear demonstration of the similarities and differences between different systems, and easy identification of the common resources. Using the architecture description model developed in this research, the consolidation of national IT resources can be promoted, and non-expert IT users can easily recognize the architecture of their systems. In addition, more efficient and systematic IT resource management can be achieved using our model.

In spite of controversial debates on aesthetic issues of computer-generated electronic music, rapid advancement of music technologies in the past decade have resulted proliferation of using virtual software synthesizers and samplers in music composition. Computer-based music production platform has become not only a norm among some of contemporary music composers but also vital apparatus for their compositional process. There are two imperative parts of this compositional process involving sampling in computer-based music production, which are commercially available sample libraries that include pre-recorded audio samples, and music production software that processes them. The purpose of this study is to investigate the process and effectiveness of reconstructive compositional process utilizing distinctive features of sampling on computer music production software. This study addresses issues such as: the definition of audio sampling, how sampling is incorporated in compositional process, and what features of music production software are particularly effective in various musical expressions. The result of this study will hopefully accommodate and fulfill the needs of electronic and acoustic musicians' creativeness.

These days, XML is accepted and used to e-commerce market broadly. But by reason of XML document has autonomy of expression that can exist same form logically but several other forms physically, several problems ran happen in application that judge effectiveness as physical form such as XML digital signature. Therefore, it is recommending to propose and use Canonical XML algorithm to change identical XML document physically equally logically in W3C to solve this problems. We implemented system that run Canonical XML algorithm that suggested in W3C that can change to more elaborate regular document. Thus, interpretable with other application that takes W3C recommendation. Also, as well as use in digital signature system for web service is useful, use in several system that physical identify is required when it exchanges XML document for web service interoperability are considered to be valuable. Moreover, Adding the transformation ability between universal encoding scheme and EUC-KR that is internal encoding scheme should be Canonical XML Algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

For the sharing and exchange of information between medical clinics, the clinical document has to be built on a standardized protocol such as a HL7-CDA. But it is difficult to exchange information between medical clinics because clinical document such as electronic medical record that include text and image, have different structure of document and type of expression. In this paper, we propose the electronic medical record system based on HL7-CDA that can share and exchange clinical information between medical institute. For this purpose, we have to design the schema of the clinical document architecture after we select the essential items of medical record and define templates. The proposed system can minimize integrating process and save parsing time when clinical information exchange and refer, by converting electronic medical record to base64 encoding scheme and integrate it in a XML document.

This Study is to propose the archival description in accordance with the paradigm shift of the archival science. The academic world of archival science in North America treated the electric record in 1990 and the authenticity of electric record in the beginning of 2000, the flow of Study recognizing the microscopic and the cultural discussion appeared recently. This may be called the paradigm shift of archival science. This may be according to the influence of the informatization and the technology. However, the community archives, the everyday life archives recognizing the microscopic and the cultural discussion, etc. Namely, the everyday life, the village, the community archives are the effort to leave the excluded and the neglected voices from the existing discussion of archival science on record. However, the currently existing methodology to archive the community archives based on the perception of these switched recognition is limited. Especially the description of the various standards being used in the public territory is being adapted as it is. The characteristic and the individuality of the community and the community archive cannot be reflected through the archival description standard. We should understand the community archive in accordance with the paradigm shift, need the archival description method capable of expressing this suitably. The post-standard not the existing archival description method has been necessary. This should be carried out together in accordance with the view point of the paradigm shift and the view point of the objective and the direction of community. Hence, first the archival description and the paradigm shift have been examined theoretically and the archival description of community archive being operated currently has been analyzed. The archival description is to be proposed in accordance with the paradigm shift capable of calling 'the archival description of Korean Human Right' by pointing out the limit of archival description standard through the analysis and further by investigating the archival description of the fraternity archive project.

XML(Extensible Markup Language) is an emerging standard for data representation and exchange in e-commerce and internet-based information. However, to realize this potential, it is necessary to be able to extract structured data from XML documents and store it in a database, as well as to generate XML documents from data extracted from a database. Although many DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS and platform-independent XML middleware as well. In this paper we describe such a XML2RDB middleware, that solves the following problems . generating relational schema from XML DTDs for storage of XML documents, importing data from XML documents into relational tables, creating XML documents according to a XMLQL(XML Query Language) from data extracted from a database.

XBRL is fundamentally defined as a structure that enterprises expand based on KGAAP 2.1 developed by the Korea branch of XBRL. Each enterprise selects its type of business and must check and choose the tag suitable to each enterprise. Since a complicated part such as expanding tag exists, there is a difficulty to prepare document through the step of tag expansion and data input. Although the expressive way of style provides the standards using the presentation structure and label structure provided fundamentally by XBRL, there is a complicated problem of using XBRL Processor. The electronic public disclosure system of the Financial Supervisory Service (DART) and Korea Exchange (KIND, KEDIS) use the Markup Language of SGML, XML and XBRL as format language. The procedure of defining document and process method vary in accordance with the characteristics of each language. This study analyzes the effect by step in accordance with format language of each electronic disclosure system and studies a direction of format language.
