This study is to analyze the characteristics of 2019 revised RDA and suggest the consideration in aspects of cataloging using the literature reviews. The following 3 things are suggested with analyzing the revised RDA. First, high quality data such as supplementing cataloging data and constructing vocabulary encoding schemes should be needed to transform bibliographic data to linked data for the semantic web. Second, MARC should be expanded to accept the new conept of LRM and linked data being reflected in revised RDA because MARC is the unique encoding format untile linked data will be transformed from MARC data. Third, the policy statement and the application profile are needed for describing resource consistently because each entity and element has own condition and option, and there are different elements for applying rules in revised RDA. Based on this study, the RDA related researches should be in progress such as exapanding BIBFRAME as well as MARC to accept the new concepts in revised RDA, and, also, reflecting and accepting RDA being able to use revised RDA rules and registries in libraries and nations that have been faced to revise their own cataloging rules.

Cataloging principles, cataloging rules, and encoding formats should considered LRM acceptance because LRM replaced FRBR as the conceptual model. This study identifies considerations for BIBFRAME acceptance of expression and representative expression attributes in LRM by using literature reviews and expert interviews. Primarily, work in BIBFRAME without expression as entity could map to work and expression of LRM and sustain expression by linking 2 works (work and expression). Second, BIBFRAME must consider association between representative expression attributes and specific expressions whose values can be transferred to the representative expression attributes. Third, representative expression attributes are different according to work types in LRM, and language, media, intended audience, and scale, that can be used as representative expression attributes in BIBFRAME, should be changed in class. Fourth, relation properties should be articulated for expanding networks between expressions originated from work in BIBFRAME. This study analyzes LRM and BIBFRAME by focusing on expression entity and representative expression attributes. More LRM study is needed on cataloging principles and cataloging rules.

As cyber-attacks become more intelligent and sophisticated, the importance of Security Operations Center(SOC) has increased and the number of SOC has been increasing. In order to cope with cyber threats, institutions and organizations use a variety of cyber security standards to create business procedures. However, SOC often need to be improved in accordance with the SOC environment because they collaborate with managed security service specialists rather than their own personnel. The NIST cyber security framework, information security management system, and managed security service companies were compared and analyzed. As a result, it was found that the NIST CSF is a framework that is easy to apply to managed security service, The content was judged to be insufficient. Therefore, in this study, NIST CSF was used as a reference model to derive the management items required for SOC environment, and the necessity, importance and ease of each item were confirmed through an Delphi technique and an improved cyber security framework was proposed.

With the enactment of regulations on confidential records management, the management of confidential records has become more important than ever. However, there remains no management method in the field of records management that takes the feature and values of confidential records into consideration. For this, this study processed electronically confidential records managed in a non-electronic environment. In addition, we developed a system that will allow public institutions to manage confidential records independently, that will prevent loss of information because of loss of or damage to the confidential records, and that can be used conveniently in the digital security environment of authorized users to establish a foundation for commercial management. In this study, we analyzed the system configuration requirements according to the international standard for the records management of a confidential records management system and system-related issues such as system design based on the analyzed requirements, system security and encryption, and metadata, the overall process of establishing and outputting secret management records and standard management.

This study was intended to analyze the effects of Entrepreneurship on manufacturing(G-automobile) employees' Organizational Culture and Job satisfaction. A proposed model based on previous research was empirically tested via SPSS 25.0 using 349 valid samples collected from current employees of G-automobile Enterprises in Chang Won. The results of the empirical analysis are summarized as follows. First, Entrepreneurship(Innovativeness, Proactiveness, Risk-taking) had direct effects on Job satisfaction. Second, Entrepreneurship(Innovative, Enterprising, Risk-sensitive) had direct effects on Organizational Culture. Third, as a result of analyzing the effect of Organizational Culture on Job satisfaction, it was found that Organizational Culture(Development Culture, Rational Culture) had a significant positive(+) effect on Job satisfaction. The results of this empirical analysis are considered to be related to the rigid organizational culture of automobile manufacturing companies with many male-oriented field workers. In the future, research involving other automobile manufacturers is expected to be needed.

This study analyzes the difference in the awareness of Korean Unification among age groups based on survey data. It is verified by statistical model analyses that the ratio of agreement for Korean Unification increases with the age growth, but after the highest peak at the age group of 44 ~ 53 years, the ratio of agreement gradually decreases. The statistical model shows that the age group of 44 ~ 53 years old has 2.5 times higher odds of agreement than the age group of 24 ~ 33 years old and the odds of female to male is 0.56. Meanwhile, the ratio of increase in the agreement, aligned with the increasing age groups, shows 4.3 times higher for males than females. The difference in the ratio of agreement in the overall age groups is estimated to be contributed the most by the significant difference in the ratio of agreement for Korean Unification between the young male generation (in their 20s and 30s) and the middle-aged male generation (in their 40s and 50s).

This study is to find a resource description methods applying RDA 2020 through comparing original RDA and RDA 2020, identifying the characteristics of RDA 2020, and describing practical resources focusing on manifestation applying the rules of RDA 2020. Several things should be considered for practical cataloging manifestation by RDA 2020. First, it is necessary to figure out which among the four recording methods are allowed by the elements of entities. Second, each library should develop its own application profile which specifies the elements be used for the resource description, supports the practical resource description, and makes effective resource description based on minimum description. Third, a template for encoding format could be created based on the application profile. This study will be able to provide practical help when cataloging librarians describe resources with applying RDA 2020.

In this study, we propose a plan to reflect LRM in various library-related standards or systems through analyzing the reflection of LRM in RDA. To this end, LRM and RDA 2020 were analyzed in terms of entities, relationships, attributes, and encoding schemes. First of all, for the mapping of entities, relationships, and attributes, all properties and relationships were extracted for each entity of RDA, LRM elements corresponding to each property and relationship were found and mapped, and encoding schemes were additionally compared. As a result, the things to consider in the standards and systems to which LRM is to be applied are: first, entities development considering the LRM hierarchy; second, new relation or shortcut path relation development; third, attributes expansion according to the entities considering the LRM hierarchical structure, and fourth, the development of various encoding scheme. Through this study, it will be possible to find an application plan using the application of RDA as a model in standards or systems to accept LRM.

Various influence-related relationships in Social Network Services (SNS) among users, posts, and user-and-post, can be expressed using links. The current research evaluates the influence of specific users or posts by analyzing the link structure of relevant social network graphs to identify influential users. We applied the concept of mutual interactions proposed for ranking semantic web resources, rather than the voting notion of Page Rank or HITS, to blogosphere, one of the early SNS. Through many experiments with network models, where the performance and validity of each alternative approach can be analyzed, we showed the applicability and strengths of our approach. The weight tuning processes for the links of these network models enabled us to control the experiment errors form the link weight differences and compare the implementation easiness of alternatives. An additional example of how to enter the content scores of commercial or spam posts into the graph-based method is suggested on a small network model as well. This research, as a starting point of the study on identifying influential users in SNS, is distinctive from the previous researches in the following points. First, various influence-related properties that are deemed important but are disregarded, such as scraping, commenting, subscribing to RSS feeds, and trusting friends, can be considered simultaneously. Second, the framework reflects the general phenomenon where objects interacting with more influential objects increase their influence. Third, regarding the extent to which a bloggers causes other bloggers to act after him or her as the most important factor of influence, we treated sequential referencing relationships with a viewpoint from that of PageRank or HITS (Hypertext Induced Topic Selection).
