Purpose - Korean exports account for a vast proportion of Korean GDP, and large volumes of Korean products are sold in the United States. Identifying and characterizing actual and potential product hazards related to Korean products is critical to safeguard Korean export trade, as severe quality issues can impair Korea's reputation and reduce global consumer confidence in Korean products. In this study, we develop country-of-origin-based product risk analysis methods for social media with a specific focus on Korean-labeled products, for the purpose of safeguarding Korean export trade. Design/methodology - We employed two social media datasets containing consumer-generated product reviews. Sentiment analysis is a popular text mining technique used to quantify the type and amount of emotion that is expressed in the text. It is a useful tool for gathering customer opinions regarding products. Findings - We document and discuss the specific potential risks found in Korean-labeled products and explain their implications for safeguarding Korean export trade. Finally, we analyze the false positive matches that arise from the established dictionaries that were used for risk discovery and utilize these classification errors to suggest opportunities for the future refinement of the associated automated text analytic methods. Originality/value - Various studies have used online feedback from social media to analyze product defects. However, none of them links their findings to trade promotion and the protection of a specific country's exports. Therefore, it is important to fill this research gap, which could help to safeguard export trade in Korea.

With the proliferation of artificial intelligence technology, it is becoming important to obtain, store, and utilize scientific data in research and science sectors. A number of methods for extracting meaningful objects such as graphs and tables from research articles have been proposed to eventually obtain scientific data. Existing extraction methods using heuristic approaches are hardly applicable to electronic documents having heterogeneous manuscript formats because they are designed to work properly for some targeted manuscripts. This paper proposes a prototype of an object extraction system which exploits a recent deep-learning technology so as to overcome the inflexibility of the heuristic approaches. We implemented our trained model, based on the Faster R-CNN algorithm, using the Google TensorFlow Object Detection API and also composed an annotated data set from 100 research articles for training and evaluation. Finally, a performance evaluation shows that the proposed system outperforms a comparator adopting heuristic approaches by 5.2%.

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.

This paper aims to introduce the case of operating electronic document system and record management system as one system called i-Works at Korea Midland Power Company. i-Works combines intelligent services, such as artificial intelligence and a chatbot, as a supplementary tool for record management. As such, the preparation process and progress direction for the development of the record management system is introduced, an in-depth review of real-time transfer and utilization of the functional classification system to enhance the utilization of the current records is presented, and new technologies, such as artificial intelligence for an efficient management of the increasing number of electronic records, are established.

In order to use the VR HMD, operation through separate controllers in both hands is required. Methods for text input in VR include a method of selecting virtual keyboard keys on the screen one by one using a controller, a method of inputting through a keyboard that is a resource of a computer by connecting a computer and VR, or a method of inputting through a keyboard that is a resource of a computer by purchasing a wireless keyboard in VR and wireless keyboard connection method. As such, the text input method in current VR equipment causes inconvenience and additional costs to users. For these reasons, most of the VR-related contents are limited to simple functions such as games or viewers, and there is a risk that VR equipment will be recognized as a simple game machine. Therefore, in this study, a multi-input interface using hand tracking provided by the Oculus Quest2 device is designed and partially implemented. Through this, it is expected that various tasks such as document work and business processing as well as games can be conveniently used using VR equipment.

The ICC is amending international trade rules such as Incoterms to respond to periodically changing international trade environments. Moreover, a drafting group has been formed for developing the eighth amendment and the Incoterms. Due to the recent development of information and communication technology, interest in smart work is increasing globally. Smart work is a concept that enables works to be performed without time and space constraints, and the mobile office is a typical form of smart work. Smart work has brought significant changes to the way that workers perform their jobs, and it has considerable impacts on international trade transactions. This study examines the impact of the development of information and communication technology on electronic trade customs and analyzes the revision process of Incoterms for electronic document informatization. Also, we provide implications for the 8th amendment of Incoterms.

With the National Archives of Korea's establishment of the Selection Criteria for Preservation Format of Digital Records (v1.0) in 2022, criteria have been formed to facilitate the selection of appropriate preservation formats for various types of digital records. With the advancement of technology, diverse electronic file types are produced. However, no specific criteria exist for records other than document types, such as PDF/A-1b. Therefore, the purpose of this paper is to derive intrinsic criteria for selecting preservation formats for audiovisual records, particularly focusing on video-type digital records, to expand the scope of the preservation format selection criteria. Initially, significant properties of video-type digital records were determined, forming the basis for the intrinsic criteria. According to these properties, the video types were categorized into container type and codec type, and three and six evaluation criteria items were derived, respectively. By structuring evaluation criteria for each attribute, this paper proposes intrinsic criteria for selecting preservation formats for video-type electronic records.

This study is to introduce the SDI(Selective Dissemination of Information) system, a typical aspect of information retrieval systems nowadays quite popular. The term "SDI" is most often used to describe systems of using electronic data processing equipment as a means of matching the terms of user-interest profile against document descriptors and selecting those documents with a specified degree of similarity to the terms of the user-interest profile. Various up-ta-date informations on SDI systems developed after the first introduction of the original idea by "Luhn" are reviewed and compared. The stage of development, structure, characteristics, and various other matters concerning the SDI systems are analyzed, and discussed.
