본 논문에서는 다양한 상호작용을 가지는 멀티미디어 문서인 SMIL 2.0 문서를 함수적 변환을 이용하여 문서의 검증방법을 제안한다. SMIL 2.0 문서는 기존 SMIL 1.0보다 더 많은 시간 관계의 기술 방법을 제공함으로서 문서 작성의 융통성은 높아지지만 상호작용에 따른 잠재적인 모순의 발생 가능성은 더욱 높다. 특히 비결정행위에 따른 미디어 객체간 상호 참조 및 이벤트 참조에 따라 발생할 수 있는 모순 검증이 필요하다. 제안하는 검증 방범은 SMIL 2.0 문서를 함수적 표현으로 변환하고 객체간 상호참조를 탐색하여 모순 유무를 나타내는 검증 프로토타입이다. 적용 예로는 상호작용을 가지는 멀티미디어 문서의 검증이다.

We have to convert XML DTD into relational database schema for storing XML Document at relational database. Hybrid inlining algorithm are used for converting XML DTD to relational database schema. But this method have some problem. That is the relational database schema have N:N relationship are created according this method are not satisfied with third normal from. Therefore, We proposed Extended Hybrid inlining algorithm for solving this problem in this paper.

Even though Sino-American relations of the Donald Trump era were perceived as predominately confrontational, with a symbolic trade war between the two, the scale of economic interdependencies between the United States and China results in either a need for collaboration or in serious losses on both sides in the case of lack of cooperation. The paper aims at analyzing economic relations between the United States of America and the People's Republic of China at the time of the Trump presidency. Analysis is based on the complex interdependence theory of Robert Keohane and Joseph Nye. The main hypothesis analyzed in the paper states: Asymmetric interdependence between the People's Republic of China and the United States of America limits the scope, intensity and length of a trade war. For the sake of the paper, economic interdependence will be analyzed. Apart from the reference to the state of the art, the document analysis and descriptive statistics are to be applied in the paper.

This document traces the new technologies development based on a deep classical Hill method improvement. Based on the chaos, this improvement begins with the 256 element body construction, which is to replace the classic ring used by all encryption systems. In order to facilitate the application of algebraic operators on the pixels, two substitution tables will be created, the first represents the discrete logarithm, while the second represents the discrete exponential. At the same time, a large invertible matrix whose structure will be explained in detail will be the subject of the advanced classical Hill technique improvement. To eliminate any linearity, this matrix will be accompanied by dynamic vectors to install an affine transformation. The simulation of a large number of images of different sizes and formats checked by our algorithm ensures the robustness of our method.

Text summarization is the task of producing a shorter version of a long document while accurately preserving the main contents of the original text. Abstractive summarization generates novel words and phrases using a language generation method through text transformation and prior-embedded word information. However, newly coined words or out-of-vocabulary words decrease the performance of automatic summarization because they are not pre-trained in the machine learning process. In this study, we demonstrated an improvement in summarization quality through the contextualized embedding of BERT with out-of-vocabulary masking. In addition, explicitly providing precise pointing and an optional copy instruction along with BERT embedding, we achieved an increased accuracy than the baseline model. The recall-based word-generation metric ROUGE-1 score was 55.11 and the word-order-based ROUGE-L score was 39.65.

Currently, DTD(Document Type Definition) Definition of Music score has been widely studied according to applications, and the methods of automatic transformation from defined DTD to XML Schema is in progress. In addition, studies of structure of DTD definition are focused on the expression of music information by individual format. In this paper, expression method of the music information by continuous string values is suggested using the fact that measure is basically a component of score, and XML Schema is also modelled. In addition, mechanism extracting the music information from XML instance which was expressed using the proposed method is presented. As a result, XML Schema taking the continuous string values could be defined, instance obtained by the proposed method results in increasing efficiency by simplicity of XPATH and reduction of search step compared to previous method. In addition, it is possible for human to make direct expression, and it is known that the instance size decreases.

MTF message is the normalized and standardized format which is used in the time when it tries to transmit data to other systems or exchanges needed information in defense message systems. XML can support variety of search functionality and is estimated to be the best way from the view of efficient presentation and exchange in internet based environment, based on advantage which is independent of hardware and software. US army brought in XML-MTF combining with XML based technology, but we do not contain such a MTF system, and necessity of MTF is increasing for combined operation between ROK and US as a lot of C4I system were transferred to Web based systems. In this paper, we make analysis of fundamental structure, organization of paragraph, witting regulation of MTF message. We present the rule of naming element and fundamental mapping rule for transformation of its XML based on it. Also, we prove that MTF message can be transformed to XML document by trying to transforming sample documents to XML document applying presented mapping rule, creating MTF message based on it and implement program which can automatically transform them to XML-MTF.

XML is emerging as a standard data format to exchange and to present data on the Web. There are increasing needs to efficiently store and to query XML data. In this paper. we propose a new schema transformation algorithm based on a common structure extracting technique from XML documents. The common structure is shared by all XML documents referenced by DTD and the uncommon structure is ununiformly appeared on all XML documents referenced by DTD. Based on the extracted common and uncommon structures, we transform XML DTD into relational database schema. We conduct a performance evaluation based on the number of the generated tables, the size of the record, query processing time and the number of joins on the query. The performance of our algorithm is compared with the existing algorithms, then in most cates, our algorithm is better than the existing ones with respect to the number of the generated tables and appearance of NULL values in the tables.

Robotic Process Automation (RPA) has attracted great attention from diverse home and foreign industries. To provide lessons learned and action principles based on real RPA adoption and application experiences, various case studies have been conducted. However, lacking is an investigation of public sector for RPA adoption, especially in Korea. To reduce the research gap, this study presents a case study of RPA adoption by a representative Korean ICT public organization, NIA (National Information society Agency). By automating a core process, entering a document to a governmental portal service, NIA has achieved various management performances in terms of cost, operation, and business impacts. Especially, by relieving four types of rigidity of public institutions (i.e. structure, human resource, tasks, and rules), Our case study result suggests that RPA enables public institutes to overcome obstacles of pursuing digital transformation. Implications and limitations for future public RPA adopters are offered.

E-commerce requires many different types of communications and an unprecedented amount of data changes hands. The many different Platforms and systems interacting require a platform neutral standard for data exchange. One of the technologies that can fill this niche is XML, the extensible markup language established as a standard by the W3C. By being standardized and platform neutral, XML to be factor in e-commerce application and using many systems In this paper, we designed XML document that is used in transaction between corporations, and implement the B2B integration system based on XML database system. Also we use XSLT that make efficient transformation XML documents for exchanging heterogeneous XML data between corporations. So, he or she can more easily and efficiently exchange XML documents between corporations using this system.
