$Chos{\check{o}}n$ Dynasty was governed by the words of king, however, if they were not announced by the form of public document, they were useless. Therefore, the form of public document was the symbol of governing activity, and it was very important to manage the public record in operating the nation affairs. However, the point we should consider is that $Chos{\check{o}}n$ Dynasty, in the case of managing the public record, edited 'the original' instead of preserving them. And so, the preservation of the public record was deeply related to the editing of history. In Late Korea dynasty, the management of the public record got into utter confusion and so many troubles were occurred. In order to resolve these problems, the movements which innovated the public record managements system was gradually extended. This movements were continued in $Chos{\check{o}}n$ Dynasty. Finally, through the several modification procedures, the rules of public record management were legislated by 'Kyong Kuk Dae Jeon'(經國大典). Especially, by laws of 'Kyong Kuk Dae Jeon', not only the daily records of Secretary Department(承政院) but also the important documents which was related to the government branch should be booked in the last decade of the year and the number of the books had to be reported to the king. This rule made certification of the fact that the king was the last confirmer of the public record management. In addition, through the procedure of printing the record of the national affairs, and the diplomatic once in three years, and then preserving that public record in the National Department(議政府), other departments responsible and the archives, the National Department practically took part in the public record management. The management system was also changed in order that the public record was virtually used and consulted before taking the procedure of immortal preservation. All public documents were classified by the definite rule and filed in a same volume. After classifying and filing, certainly, for making convenience of reference and application of public record, records were indicated by the paper card. It may be that, after the step of reference, application and indicating, the public documents were gradually transferred to the next step. In these procedures, Early $Chos{\check{o}}n$ public documents system was confirmed.

Research design, data, and methodology - This study was conducted with previous researches centered on cases applied in various industry sectors on the basis of blockchain technology. Results - General fields of blockchain application include digital contents distribution, IoT platform, e-Commerce, real-estate transaction, decentralized app. development(storage), certification service, smart contract, P2P network infrastructure, publication/storage of public documents, smart voting, money exchange, payment/settlement, banking security platform, actual asset storage, stock transaction and crowd funding. Blockchain is being applied in various fields home and abroad and its application cases can be explained in the banking industry, public sector, e-Commerce, medical industry, distribution and supply chain management, copyright protection. As examined in the blockchain application cases, it is expected to establish blockchain that can secure safety through distributed ledger in trade transaction because blockchain is established and applied in various sectors of industries home and abroad. Parties concerned of trade transaction can secure visibility even in interrupted specific section when they provide it as a base for distributed ledger application in trade and establish trade transaction model by applying blockchain. In case of interrupted specific section by using distributed ledger, blockchain model of trade transaction needs to be formed to make it possible for parties concerned involved in trade transaction to secure visibility and real-time tracking. Additionally, management should be possible from the time of contract until payment, freight transfer to buyers through land, air and maritime transportation. Conclusions - In order to boost blockchain-based logistics/distribution industry, the government, institutionally, needs to back up adding legal plan of shipping, logistics and distribution, reviewing standardization of electronic switching system and coming up with blockchain-based industrial road maps. In addition, the government, technologically, has to support R&D for integration with other high technology, standardization of distribution industry's blockchain technology and manpower training to expand technology development.

To participate in global carbon neutrality, the Korean government is also planning to carry out zero-energy building certification for all buildings by 2030 through the enforcement decree of the 'Green Building Support Act'. Accordingly, the government is providing various projects related to solar power generation, which are relatively close to life. In particular, roof-mounted photovoltaic power generation systems are attracting attention in terms of using unused space to produce energy without destroying the environment, but low power generation efficiency compared to other photovoltaic power generation facilities is pointed out as a disadvantage. Therefore, in this paper, to solve this problem, we propose an efficient solar panel angle variable system through research on the solar panel structure for single-axial solar tracking, and also consider the application environment of the roof-mounted solar power generation system. Suggests measures to prevent damage and secondary damage. In addition, it is judged that it is possible to control the solar panel based on ICT convergence and configure the accident prediction safety system to link the project-based education program.

With the improvement of the Information Technology and the change of the business environment, the dependency of business on the Information Technology shows sharply increase. The Information Technology, however, is centered on the support of the technology viewpoint and thus the influence and effect of Information Technology on the business is hardly analyzed. The information system, therefore, requires not only technology-centric support management but service-oriented and systematic introduction of Information Technology Service Management(ITSM). The domestic ITSM market is currently expanding into variety of industries like finance, telecommunication, manufacturing and public service and at the same time the consequent reconstruction process of information system is continuously under way so as to qualify for the ISO 20000 certification. Especially the public organizations rapidly adopt the ITSM, in order to improve the quality of public service together with a goal of realizing the electronic government and of managerial innovation. The existing ITSM still, however, shows the tendency of depending only on the system construction and the management on the visible requirements whereas the overall process is not likely being improved. Hence, this study suggests, focusing on the life cycle of service, the model of ITSM based on Information Technology Infrastructure Library(ITIL) v3 which is appropriate for the public service. We expect, as stated in this study, that our ITSM model shall be widely accepted to the public agencies who promote the advance campaign by setting up the ITSM or reconstructing the existing process.

The government and companies build a DDoS correspondence system hastily to protect assets from cyber threats. It has become more and more intelligent and advanced such as DDoS attack. However, when outbreaks of the social incidents such as 7.7 DDoS attack(2009.7.7) or cases of the direct damage occurred, information security systems(ISS) only become the issue in the short term. As usual, sustained investment about ISS is a negative recognition. Since the characteristic of ISS is hard to recognize the effectiveness of them before incidents occurs. Also, results of incidents occurred classify attack and detection. Detailed and objective measurement criterion to measure effectiveness and efficiency of ISS is not existed. Recently, it is progress that evaluation and certification about for the information security management system(ISMS). Since these works propose only a general guideline, it is difficult to utilize as a result of ISMS improvement for organization. Therefore, this paper proposes a framework to develop main criteria by a correspondence strategy and process. It is able to detailed and objective measurements.

Establishment of the LFQC (Liquid Fertilizer Quality Certification) system is very urgent issue for recycling livestock manure as renewable resources in Korea faced with environmental problem of manure application to land due to intensive livestock farming. In this study, we investigated relevant laws and regulations on livestock manure fertilizer, certifications of eco-friendly agricultural products, government policies on livestock manure management to establish reasonable direction of Korean LFQC (Liquid Fertilizer Quality Certification) system. As a result from this study, the liquid fertilizers in 'LFQC' system could be classified as three levels according to the usage patterns in field; 1st. Individual Farm Level (IFL), 2nd. Joint Farm Level (JFL), and 3rd. Commercial Level (CML). And finally, we found some characteristics in 'Main Level-Grading Factors' of liquid fertilizer such as fertilizing value, harmfulness, stability, uniformity, economic effect, storage potential, commercial value, functionality. Those items were considered to be the key factors for the establishment of 'LFQC' system. More research on 'Evaluation Standards' for concrete guideline and on the 'Main Level-Grading Factors' be needed to complete Korean LFQC system.

One of the most important paradigms in society has recently been a set of efforts to prepare for the future and to protect the environment by saving carbon that occurs in everyday life as well as in the industry. In order to successfully deal with this new paradigm, Korean government has adopted and implemented various policies including the green certification, the development of green technologies and green growth. Many agencies and organizations in both public and private sectors have established plans about the carbon savings and performed a lot of research using IT technology. For example, attempts have been made in Korea to use as electronic documents instead of paper documents using these green IT and mobile devices. This paper proposes a 'Paperless' waiting order count system using QR code and mobile phone as an example of green IT for 'Low carbon and Green growth'.
