In this paper, I examined specific characteristics of the Tables of Transactions for Records Scheduling(TRS) (記錄物分類基準表 ; Kirokmul-Bulyukijun - Pyo) system by Public Records and Archives Act(PRA Act, No. 5709, 1999). All staffs and employees in governmental agencies of Korea must register, classify and dispose of their official records according to TRS by the Presidential Regulation for the application of PRA Act(No. 17050, 2000). Namely, the criteria of TRS is applicable to all stages of records lifecycle from creation to disposition(transfer to Archives or legal destruction). In the theoretical and methodological area, therefore, it is absolutely important that records managers and archival professionals in Korea make analysis on functions and characteristics of TRS by PRA Act. In the first, my examination take notice of possibility of 'adequate and proper documentation' about activity of the executive organization in TRS system. Other attention is that records management according to TRS means managing of records not only as physical entities but as logical entities which imply content and context of creation and use. In other hand, I wish to account for reasonable separation consideration for continuing utility of archives from current use of records throughout agencies duration Another theme of discussion in this paper is the theoretical framework which give account of TRS's characters. In conclusion, accountability for characteristics of TRS system could have been found in counterproposal view including the concept of Records continuum and the notion of Recordkeeping regime in Australia based on rethinking about Records lifecycle model. In the extent of practical area, more or less, it is imbalanced method that compare TRS by PRA Act to Recordkeeping regime based on Records continuum. Nevertheless, the concept and notion is suitable framework that give account of the prospect of recordkeeping system under PRA Act.as well as the meaningful characteristic of TRS.

Collecting and managing information on all-round activities of students not only helps to improve school life adjustment and satisfaction, but also serves as the basis for preventive student support for academic warnings or dropouts. Therefore, in guiding students, it is necessary to integrate various information of students and provide them to the instructor quickly and accurately. In this study, in the special environment of an organization in which student information is scattered in several systems, a system model is proposed that not only integrates and provides student information to instructors quickly, but also saves cost and effort. And we tested the effectiveness of the proposed system model by developing a simple web page. As a result, it was confirmed that the proposed model provided information necessary for student guidance in an integrated, multifaceted, and instantaneous manner, and that user satisfaction was improved through an improved UI.

Document page segmentation is an important step in building a quality optical character recognition module. The study examined already existing work on the topic of page segmentation and focused on the development of a segmentation model that has greater functional significance for application in an organization, as well as broad capabilities for managing the quality of the model. The main problems of document segmentation were highlighted, which include a complex background of intersecting objects. As classes for detection, not only classic text, table and figure were selected, but also additional types, such as signature, logo and table without borders (or with partially missing borders). This made it possible to pose a non-trivial task of detecting non-standard document elements. The authors compared existing neural network architectures for object detection based on published research data. The most suitable architecture was RetinaNet. To ensure the possibility of quality control of the model, a method based on neural network modeling using the RetinaNet architecture is proposed. During the study, several models were built, the quality of which was assessed on the test sample using the Mean average Precision metric. The best result among the constructed algorithms was shown by a model that includes four neural networks: the focus of the first neural network on detecting tables and tables without borders, the second - seals and signatures, the third - pictures and logos, and the fourth - text. As a result of the analysis, it was revealed that the approach based on four neural networks showed the best results in accordance with the objectives of the study on the test sample in the context of most classes of detection. The method proposed in the article can be used to recognize other objects. A promising direction in which the analysis can be continued is the segmentation of tables; the areas of the table that differ in function will act as classes: heading, cell with a name, cell with data, empty cell.

Data scientists are new knowledge workers representing the knowledge economy era. Knowledge workers perform unstandardized works that solve ambiguity-intensive problems. Therefore, self-leadership, which emphasizes self-motivated, autonomous judgment and execution, significantly influences their work-related outcomes. Even knowledge workers have high occupational commitment, they usually show low organizational commitment. Knowledge workers' intention to leave is also relatively high due to this reason. This study focused on data scientists' self-leadership, predicted that self-leadership would increase an organization's commitment and intention to leave. Based on the trait activation theory(TAT), the author also confirmed how perceived job autonomy enhances self-leadership influences. Results showed that data scientists' self-leadership significantly lowered intention to leave through organizational commitment and this mediating effect was moderated by perceived job autonomy. This study broadened the theoretical understanding the effects of knowledge workers' self-leadership and presented practical implications for managing data scientists.

This study tried to examine the relationship between superior leadership and emotional support from co-workers on task performance through performance evaluation fairness and self-efficacy in order to find factors that affect the task performance of a company in an uncertain market environment. For this purpose, 500 copies of questionnaire data were collected from corporate employees, and the research hypothesis was verified using Smart PLS 3.0. As a result of the study, superior leadership and emotional support from co-workers showed a positive (+) effect individually on the fairness of employee performance evaluation, Performance evaluation fairness showed a positive (+) effect on self-efficacy. Through this study, it was found that the fairness and self-efficacy of the performance evaluation accepted by employees affects work performance, providing a theoretical foundation for subsequent researchers. Practical implications are suggested to inspire employees to take on a challenge by managing them properly. In future research, based on the results of this study, various studies are needed on the factors that an organization must have for task performance.

In recent years, the term "art archives" has become increasingly popular, with the growing use of archives in exhibitions and program planning within domestic cultural and arts institutions. The need for art archives has been raised for reasons such as establishing the identity of art and culture and providing basic resources for academic research; however, they are now being recognized as a direct resource and service for users. Accordingly, research has also been conducted on the values, policies, and management practices of art archives in the archiving field. Nevertheless, there is a lack of research on management methodologies that can be applied to institutions that manage art archives. In particular, for the efficient use of art archives, classification, organization, and systematic management of descriptive areas must be preceded. But, There are different methods of managing art archives depending on the type of collection, the management institution, and the characteristics of the collection resources, which, in turn, makes it difficult to apply a consistent methodology for classification and description. Based on actual cases from The Art Archives, Seoul Museum of Art, this study examined the types and categories of arts, and presented the establishment of a classification system and archival description rules.

Hydrogen is promising a candidate for energy supporting the carbon neutrality policy for greenhouse gas reduction, which is being promoted in several countries, including Korea. Although challenging efforts-such as lowering the costs of green hydrogen production and fuel cells-remain, hydrogen fuel cell electric vehicles (FCEVs) are expected to play a significant role in the energy transition from fossil fuels to renewable energy. In line with this objective, the hydrogen FCEV working group in the International Organization for Standardization (ISO) compiled and revised international standards related to hydrogen refueling stations as of 2019. A well-established hydrogen quality management system based on the standard documents will increase the reliability of hydrogen charging stations and accelerate the use of FCEVs. In this study, among the published ISO standards and other references, the main requirements for managing charging stations and developing related techniques were summarized and explained. To respond preemptively to the growing FCEV market, a continuous hydrogen quality monitoring method suitable for use at hydrogen charging stations was proposed.

As the embedded software for weapon system is embossed, the information management system is required to service and manage the technical information of embedded software systematically. But the technical information documents are managed by its own organization separately, it's hard to service the information and share it with anyone who need. In this paper, to manage the embedded software information systematically, we analyze the information management system built in 2004 and the defence law/rule. Also we distinguish the software information from defence laws to manage systematically and analyze the requirements of the information system. Based on these, we suggest implementing the management system to increase efficiency of managing the weapon embedded software information. Through this, we can improve the utilization and reusability of the weapon embedded software.

Investment authorities are broad financial institutions that carefully manage investments on behalf of the national government using a long-term value development approach. To provide a stronger structure or framework for In-vestment Authorities to govern the distribution of funds to public and private markets, we've started research to create a blockchain-based prototype for managing and tracking numerous finances of such authorities. We have taken the case study of Oman Investment Authority (OIA) of Sultanate of Oman. Oman's wealth is held in OIA. It is an organization that oversees and utilizes the additional capital generated by oil and gas profits in public and private markets. Unlike other Omani funds, this one focus primarily on assets outside the Sultanate. The operation of the OIA entails a huge number of transactions, necessitating a high level of transparency and administration among the parties involved. Currently, OIA relies on various manuals to achieve its goals, such as the Authorities and Responsibilities manual, the In-vestment Manual, and the Code of Business Conduct, among others. In this paper, we propose a Blockchain based framework to manage the operations of OIA. Blockchain is a part of the Fourth Industrial Revolution, and it is re-shaping every industry. The main components of every blockchain are assets and participants. The funds are the major assets in the proposed study, and the participants are the various fund shareholders/recipients. The block-chain's transactions are all safe, secure, and immutable, and it's part of a trustless network. The transactions are simple to follow and verify. By replacing intermediary firms with smart contracts, blockchain-based solutions eliminate any middlemen in the fund allocation process.
