A microservice architecture that accommodates the heterogeneity of various development environments and enables flexible maintenance can secure business agility to manage services in line with rapidly changing requirements. Due to the nature of MSA, where communication between microservices within a service is frequent, the boundary security that has been used in the past is not sufficient in terms of security, and a Zerotrust system is required. In addition, as the size of microservices increases, definition of access control policies according to the API format of each service is required, and difficulties in policy management increase, such as unnecessary governance overhead in the process of redistributing services. In this paper, we propose a microservice architecture that centrally manages policies by separating access control decision and enforcement with a general-purpose policy engine called OPA (Open Policy Agent) for collective and flexible policy management in Zerotrust security-applied environments.

If the blockchain means storing information in a distributed environment that cannot be forged or altered, it is mentioned that this is similar to what librarians collect, preserve, and share authoritative information. In this way, this study examined blockchain technology as a way to collect and provide reliable information, increase work efficiency inside and outside the library, and strengthen cooperative networks. This study attempted to propose various ways to utilize blockchain technology in book relations based on literature surveys and case studies in other fields. To this end, this study first analyzed the field and cases of blockchain application to confirm the possibility and value of blockchain application in the library field, and proposed 12 ways to utilize it based on this. The utilization model was proposed by dividing it into operation and service sectors. In the operation sector, it is a digital identity-based user record storage and authentication function, transparent management and traceable monitoring function, voting-based personnel and recruitment system, blockchain governance-based network efficiency function, and blockchain-based next-generation device management and information integration function. The service sector includes improved book purchase and sharing efficiency due to simplification of intermediaries, digital content copyright protection and management functions, customized service provision based on customer behavior analysis, blockchain-based online learning platforms, sharing platforms, and P2P-based reliable information sharing platforms.

The advent of e-government following the information revolution has affected public records systems. Records management should now be changed into an environment for establishing a national records management system based on the Internet of things (IoT), cloud, big data, and mobile (ICBM), and it is time to make a fresh start toward a next-generation records management system that responds to changes in the environment. Ultimately, it is time for a records management system that ensures a proper way of dealing with new environmental changes. It has been nearly 20 years since the Public Records Management Act was enacted in 1999, and its complete amendment was made in 2006 so that electronic records could be efficiently managed. When recompliance management needs to be rechecked, a full redesign is required to enable the current legal system to respond to the new circumstances in the present day. Therefore, this study is intended to suggest ways to improve the new records management legal system as the environment changes over the next generation and lay the legal groundwork for innovation in the national records management system.

This study is a basic study to establish a comprehensive plan for operating the Hanam Library, a regional base library that will be built in Gwangsan-gu, Gwangju Metropolitan City. We investigated opinions about the collection, library program, role and task of a regional base library and the operation of the cooperative shared storage. As a result of the study, the information resources that users prefer are a book form of the literary subject, and preferred library services are the use of information resources and participation in cultural events. Public library librarians answered conducting user-centered services and carrying out a cooperative projects between libraries are important and they recognized cooperative acquisition as a task should be performed first. In addition, opinions about the operation of cooperative shared storage is generally positive. The regional base library managers said that it is important to establish library governance by clarifying the status and role of the library and that as a public library, and to promote information services and cooperation projects for local users. The results of this study can be expected to be the useful basic material for the establishment of the Hanam Library comprehensive operation plan.

It is desirable to invest in wine that increases its value, but wine investment itself is unfamiliar in Korea. Also, the process itself is unreasonable, and information is often forged, because pricing in the wine market is done by a small number of people. With the right solution, however, the wine market can be a desirable investment destination in that the longer one invests, the higher one can expect. Also, it is expected that the domestic wine consumption market will expand through the steady increase in domestic wine imports. This study presents the consortium block chain framework for revitalizing the wine market and enhancing transparency as the "right solution" of the nation's wine investment market. Blockchain governance can compensate for the shortcomings of the wine market because it guarantees desirable decision-making rights and accountability. Because the data stored in the block chain can be checked by consumers, it reduces the likelihood of counterfeit wine appearing and complements the process of unreasonably priced. In addition, digitization of assets resolves low cash liquidity and saves money and time throughout the supply chain through smart contracts, lowering entry barriers to wine investment. In particular, if the governance of the block chain is composed of 'chateau-distributor-investor' through consortium blockchains, it can create a desirable wine market. The production process is stored in the block chain to secure production costs, set a reasonable launch price, and efficiently operate the distribution system by storing the distribution process in the block chain, and forecast the amount of orders for futures trading. Finally, investors make rational decisions by viewing all of these data. The study presented a new perspective on alternative investment in that ownership can be treated like a share. We also look forward to the simplification of food import procedures and the formation of trust within the wine industry by presenting a framework for wine-owned sales. In future studies, we would like to expand the framework to study the areas to be applied.

The overarching question of this study is how a typical rice cultivation system in Gimje, Korea was keeping up with the triple-win challenge of climate-smart agriculture (CSA). To answer this question, we have employed (1) quantitative data from direct measurement of energy, water, carbon and information flows in and out of a rice cultivation system and (2) appropriate metrics to assess production, efficiency, GHG fluxes, and resilience. The study site was one of the Korean Network of Flux measurement (KoFlux) sites (i.e., GRK) located at Gimje, Korea, managed by National Academy of Agricultural Science, Rural Development Administration. Fluxes of energy, water, carbon dioxide (CO₂) and methane (CH₄) were directly measured using eddy-covariance technique during the growing seasons of 2011, 2012 and 2014. The production indicators include gross primary productivity (GPP), grain yield, light use efficiency (LUE), water use efficiency (WUE), and carbon uptake efficiency (CUE). The GHG mitigation was assessed with indicators such as fluxes of carbon dioxide (F_CO2), methane (F_CH4), and nitrous oxide (F_N2O). Resilience was assessed in terms of self-organization (S), using information-theoretic approach. Overall, the results demonstrated that the rice cultivation system at GRK was climate-smart in 2011 in a relative sense but failed to maintain in the following years. Resilience was high and changed little for three year. However, the apparent competing goals or trade-offs between productivity and GHG mitigation were found within individual years as well as between the years, causing difficulties in achieving the triple-win scenario. The pursuit of CSA requires for stakeholders to prioritize their goals (i.e., governance) and to practice opportune interventions (i.e., management) based on the feedback from real-time assessment of the CSA indicators (i.e., monitoring) - i.e., a purpose-driven visioneering.

The amount of unstructured data generated online is increasing exponentially and the analysis of text data is being done in various fields. In order to identify the research trends on the platform government, the title, year, academic society, and abstract information of the academic papers on the subject of platform government were collected from the database of the domestic papers, DBPIA(www.dbpia.co.kr). The results of the existing research on the platform government and related fields were analyzed based on each stage of the national informatization promotion. The technology, service, and governance topics were extracted from papers on platform government and the trends of core topics were analyzed by year. Entering the era of the intelligent information society, this study has significance for providing the basis for defining a new role of government - the platform government that sets the stage for the private sector to lead the innovation, and plays the role of an 'enabler' and 'facilitator' instead. The purpose of this study is to understand the platform government research through objective analysis of its trends. Looking for future directions, this study will contribute to future research by providing reference materials.

The land under Japanese-type names remains in the Korean cadastral record as an official register due to land exploitation, land and field survey programs, and the forceful name-changing system of Japan during its colonial era. This research aims to find a measure to survey and organize such land. Research details are as follows. First, this research put together the purpose and status of land exploitation in the Japanese colonial era. Japan wanted to reduce its population through agricultural emigration of the Japanese and increase food supply by producing more crops in Joseon. Therefore, land of three southern provinces, the breadbasket of Korea, was intensively plundered. Secondly, this research organized how Joseon people changed their surnames into Japanese-style ones. The initially voluntary name-changing system became mandatory and about 3.22 million households (79.3%) reported the change of their names. Thirdly, this research established a process to survey land under Japanese-style names. Fourthly, this research yielded visible outcomes as a result of the pilot program. Especially, it revealed 718 lots as land under Japanese-style names and 8 lots as land under the names of Japanese. Fifthly, this research presented internal & external collaboration and cooperation measures for surveys.

Nowadays, the IS project is getting more and more complicated and large-scaled. Many researchers and practitioners are interested in the IS development methodologies, automated tools and techniques to decrease project failure and to increase IS project performance. This research is to seize the management level of PMO affecting on the IS project, as a new method to increase the IS project development performance. As a result of surveying the present PMO operation state with banks which are the leading industry to accept the PMO in Korea, technology support management and infrastructure management are the core functions to affect the IS performance including schedule management, quality management, and user and stakeholders' satisfaction. Also, the PMO management level is the important point of IS project success. Among the 5 levels PMI suggested, PMO can implement the project effectively at least at the third level. Korean companies introducing the PMO have to do research the PMO core functions and the management levels according to the project scale, and review the distinctive features of their organization to increase the maturity of IS project. This research has been proved through the Full Structural Equation Model. The results show that the five core functions of PMO have relationship with the IS project performance.

Documenting environmental conflicts will be a priority target for documenting localities, because those conflicts are critical events that make intensive 'place experiences' of local residents. This study is to design a narrative structure for documenting conflicts in the process of Transmission Towers Construction in Miryang. This study begins with analysing the characteristics of environmental conflicts, and draws a conflicts documentation model including basic rules, narrative structure and development process. Basic rules are set up as mixed documentation of memory and evidence, application of 'frame', and dynamic description. Based on the rules, this study suggests a dynamic and open narrative framework adopting the metadata model of ISO 23081. This model is applied to documenting Transmission Towers Construction Conflicts in Mi-ryang. The full narrative and 'frame' of the conflicts are set after analysing development and issues of the conflicts, stakeholder, and properties of each conflict problem. Records descriptions are related to the context(each event occurred in the conflicting conditions, mandates, and stakeholder) descriptions to make multiple narratives in digital environments. Event description contains elements for articulating the 'frame' of each party of the conflict. The merits of this model are; i) to accumulate the adequate context information systematically by adopting dynamic narrative model, and ii) to acquire the new items and connect them to related items easily and consistently through multi-entity description. This documentation model of environmental conflicts may support to shape the collective memory of community, and to achieve good governance by managing conflicts in the process of locating non-preferred facilities with due regard to values and perceptions of residents and communities.
