In this study, we developed the system that can collect and store environmental disaster data into the database and use it for environmental disaster management by converting structured and unstructured documents such as images into electronic documents. In the 4th Industrial Revolution, various intelligent technologies have been developed in many fields. Environmental disaster information is one of important elements of disaster cycle. Environment disaster information management refers to the act of managing and processing electronic data about disaster cycle. However, these information are mainly managed in the structured and unstructured form of reports. It is necessary to manage unstructured data for disaster information. In this paper, the intelligent generation approach is used to convert handout into electronic documents. Following that, the converted disaster data is organized into the disaster code system as disaster information. Those data are stored into the disaster database system. These converted structured data is managed in a standardized disaster information form connected with the disaster code system. The disaster code system is covered that the structured information is stored and retrieve on entire disaster cycle. The expected effect of this research will be able to apply it to smart environmental disaster management and decision making by combining artificial intelligence technologies and historical big data.

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.

Existing B2B, B2C computer systems and applications that executed business trans-actions were the client- server based architecture which consists of heterogeneous hardware and software including personal computers and mainframes. Due to the active boom of electronic business, integration and compatibility of exchanged data, applications and hardwares have emerged as hot issue. This paper designs and implements a message transport system and a document transformation system in order to solve the interoperability problem of integrated logistics system in e-Business when doing electronic business. Message transport system integrated ebMS 2.0 which is standard business message exchange format of ebXML, the international standard electronic commerce framework, and JMS of J2EE enable to ensure reliable messaging. The document transformation system could convert non-standard XML documents into standard XML documents and provide the web services after integrating message system. Using suggested business scenario and various test data, our message oriented system preyed to be interoperable and stable. We participated ebXML messaging interoperability test organized by ebXML Asia Committee ITG in oder to evaluate and certify the suitability for message system.

The physical access or control of records with material entities is relatively easy. However, in the case of electronic records, due to its heightened applicative aspect that allows anyone with the authority to have access over the data, it requires an appropriate standard and stability to ensure the authenticity and integrity of electronic records. This study performed functional evaluation by extracting the minimum critical items from the national functional requirements documents and standards to explore the access control function that play an important role for the standard records management system to maintain quality requirements of electronic records. Based on this checklist, it evaluates whether the standard records management system properly carries out the access control function and investigates the current condition of application to practical records management work. Records managers generally do not use access control function, which may be because they do not feel the necessity, since the application of records management system is not yet actively promoted. In order for the standard records management system to be developed to become a more active system, it requires system improvement as well as considerations for below factors: First, although the necessity of establishing access control conditions is already recognized, it requires a clear stipulation of the regulation. Second, measures must be taken to implement access control in the records management system through document security solution. Third, it requires self-reflection of records manager, who utilizes the records management system. Instead of placing all responsibility on the National Archives, which established the system, professionals must further develop the system through continuous evaluation and improvement. Finally, a general discussion is required to publicize the issue of functional improvement of records management system. Although there is a bulletin board already created for this purpose, its users are extremely limited and it only deals with current problems. A space in online as well as in offline is required to solve the fundamental problems and exchange opinions.

6LoWPAN is IPv6 packets transmission technology at Sensor network over the IEEE 802.15.4 Standard MAC and Physical layer. Adaptation layer between IP layer and MAC layer performs fragmentation and reassembly of packet for transmit IPv6 packets. RFC4944, IETF 6LoWPAN WG standard document define packet fragmentation and reassembly. In this paper, we propose the IRM(Immediate Retransmission Method) and SRM(Selective Retransmission Method) to manage packet fragmentation and reassembly at 6LoWPAN. Each time destination receives a fragmented packet, it sends Ack message to the source node on IRM. However, on SRM, the destination node receives all fragmented packet, it sends Ack message or Nak message to the source node. In this case, Nak message include the dropped packet number. To compare the performance of the proposed schemes, we develop a simulator using C++. The result of simulation shows the proposed schemes provider better performance than RFC4944 standard scheme.

It is not easy to access to the required data from the Web by using search engines because there are too many data selected and they do not provide enough information related to the corresponding data. Metadata is data about data. It includes information about data itself and contents of data as well. Users can acquire enough information about the corresponding data and access to the required data exactly using metadata, and therefore the data usability will be increased. In this paper, several metadata technologies and metadata models that are already in process of standardization or adopted as standards are analyzed, and the SeriCore Metadata Model for documents such as papers, project reports, technical reports, abstracts, and manuals, and graphic images that are in the field of science technologies on the Web is proposed. The SeriCore Metadata Management System that can generate, store, and retrieve metadata effectively is designed and implemented based on the SeriCore Metadata Model.

B2B e-business is an economic transaction formed between companies through various networks including internet. At present, e-business between companies partly applies information distribution between companies, but many enterprises expect that a corporate basic system will be gradually changed into XML basis if web service is earnestly materialized, so they are competing with each other in developing XML DBMS. Existing XML DBMS studies used XML DTD in order to represent the structure of XML document. Such XML DTD defines the expression of a simple type, so there are many difficulties in defining the structure of XML document. To cope with this, in this paper, the author will develop database schema generator utilizing relational database generally used in storing contents of data, on the basis of XML schema selected as a standard of W3C. Also, to store XML data, the author proposed the automatic conversion method of relational database schema that used XML schema.

A records management agency assessment must reflect the possibility of actual situations including conditions and implementation. Institutional evaluation systems and indicators tools to improve records management. However, the reality is difficult if they are not conducted through the resources and efforts of the organization. The 2017 evaluation system of the National Archives of Korea and the index, which was published in March 2016, are expected to be highly difficult to perform as the frontline field tasks of the institution for a year. It is composed of indices with questionable effectiveness that are difficult to implement on the field. Some of these include the following: three training sessions for more than 10% of all employees, submission of document archive pictures of all schools, submission of the index items of all documents, increasing the utilization level of the standard record management system for the electronic documents that have not been transferred for several years, the transfer of non-electronic documents of all institutions, reclassification of non-disclosed records, etc. It recognizes the fundamental problems of the records management system and the 2017 evaluation indicators that the National Archives has mentioned about operations. As such, now is the time to reflect the years of experience in the field to amass knowledge that will help improve records management.
