This study was conducted to develop a provenance representation model for data-type electronic records. It supports the distinction between provenance and context for the creation and management of data-type electronic records. To express both, it aims to design an extensible provenance model. For this purpose, W3C PROV is utilized as a basic model, with P-Plan and ProvONE for designing prospective provenance area. Afterward, the provenance model was extended by mapping the record management requirements. The provenance model proposed in this study is designed to represent and connect both retrospective and prospective provenance of data-type electronic records. Based on this study, it is expected to discussing the concept of provenance in the records management and archival studies area and to extending the model in the future.

This study explored the possibilities of a new approach to developing the provenance concept to electronic records in the data-driven digital environments by reviewing and adopting data provenance concepts and models. It then conducted basic literature review to develop a ground for a model representing the provenance of data-driven electronic records. In particular, it proposed to embrace to the concepts of retrospective and prospective provenance, and to develop a different model for representing provenance from records management metadata. If the model can be developed that can represent provenance independently while maintaining a dynamic relationship with records, it can be ensure the fluidity of records and even support to secure the record's attributes and play the roles of provenance. Eventually, it proposed the direction to develop the provenance model which can support the fixity of records, the reproducibility of activities, and the trustworthiness of representations. It is expected to be a fit provenance model in the data-driven digital environment.

In consideration of the drastic transformation of records management environments, this study aims to suggest the directions for redesigning the electronic records management policies at a national level. First, it clarifies the four implicit objectives of electronic records management policies since the 2006 amendment of the Public Records Management Act, such as comprehensiveness for ensuring the appropriate management of any type of digital records, digital-friendly processes for records management, proper management for guaranteeing the evidential value of digital records, and long-term preservation of digital records. Second, it examines the challenging environmental factors in the areas since 2006. Third, it reviews the achievement of the policies as well as failures based on analyzing the policy documents and data from the National Archives of Korea. Fourth and finally, it suggests core areas and directions for redesigning the electronic records management policies, emphasizing the inclusiveness for data-type electronic records.

This study acknowledges that prevailing regulation concerning for the long-term preservation of electronic records focus mainly on document types, neglecting the preservation of electronic records from various administrative information systems. With the growing interest in data management in the era of big data, it is imperative to establish clear standards for the long-term preservation of datasets. The choice of preservation format for electronic records is based on the specific standards for each type of electronic record. These standards are formulated according to the significant properties relevant to the electronic record type. This study aims to identify the significant properties of electronic records of each record type, before creating specific preservation format selection criteria for these record types. To achieve this, we reviewed and analyzed R&D studies by the National Archives of Korea and the NARA in the United States. As a result of the research, 9 significant properties were identified for database-type entities, and 7 significant properties were identified for structured data-type entities.

The introduction of new technologies is a result of the advent of the Fourth Industrial Revolution and the change from management environment to cloud environment. Changes in the production and management environments are expected because of changes in the external environment. However, responding flexibly to changes is not enough. The problem of the records management process, system, and infrastructure is intertwined, and partial reorganization is difficult to cope with changes in the external environment. Therefore, we need to redesign the whole process and study the major issues to be considered so we could redesign the process and produce an improved next-generation electronic records management.

The study aimed at exploring a direction of development of the conceptual model for organizing public digital records. First, it started with reviewing the possibility of item-oriented records and archival organization, then analyzed RIC-CM developed by ICA EGAD. Second, it investigated the hierarchies of the classes and descriptive information applied to public digital records, as well as showed the necessities of transition from paper-based model to digital-based one. Based on these, it studied to seek possibilities for organizing public digital records not by record groups but by items. Finally, this study proposed the direction of development of the next generation conceptual model for organizing public digital records.

Most of electronic medical record systems which have been built in Korean hospitals are based on source oriented medical record approach. These systems hardly satisfy diverse objectives owing to the innate imperfections in system architecture and development methodology. Thus, the hybrid of source oriented and problem oriented approach is highly desirable. The purpose of this study is to present an architecture and methodology required to construct hybrid electronic medical record system and to develop a prototype based on them. Analyzing the clinical processes and data requirements of problem oriented medical record approach we developed a software process model as weel as an architecture model which consists of legacy system, clinical data repository, problem list database, prospective plan database, user interface, and synchronization procedures.

전자상거래 기업의 장점이 고객 데이터를 이용한 원활한 데이터베이스 마케팅의 구현임에도 불구하고 아직 많은 사이버쇼핑몰들은 고객의 개별 특성이나 구매성향에 관계없이 누구에게나 동일하게 제공되는 쇼핑몰을 구축하고 있다. 본 논문에서는 갈수록 치열해지는 경쟁 환경에서 고객의 욕구를 좀 더 빠르게, 좀 더 정확하게 만족시킴으로써 고객이 다시 방문할 수 있도록 하는 방안으로 일대일 마케팅의 이론적 고찰을 통하여 맞춤형 쇼핑몰의 개념을 제시하고, NT, SQL 환경에서 ASP를 이용하여 개인화 된 맞춤형 쇼핑몰을 구축하였다. 우선 개인화 된 쇼핑몰의 구축에는 우선 개인의 프로파일, 쇼핑몰에서의 항해 기록, 실제 구매기록 등의 다양한 데이터가 이용될 수 있지만 고객의 프로파일은 항시 일정한 것이 아니라 변화하기 때문에 프로파일과 같은 정적인 정보는 다소 적절치 못할 수도 있다. 또한 고객의 욕구가 빨리 변화한다는 것을 고려한다면 고객의 정적인 정보인 프로파일을 고려하기 보다 고객의 동적인 정보를 파악, 이에 따른 개인화 된 쇼핑몰을 제공함으로써 고객의 만족도를 증진시키고 나아가 지속적인 방문을 유도하는 것이 필요하다는 것을 인식할 수 있다. 따라서 본 연구에서는 NT 환경 하에서 고객의 동적인 정보들을 분석하여 이를 바탕으로 고객의 만족을 이끌어 낼 수 있는 개인형 사이버 쇼핑몰을 시험적으로 개발하였다.
