The cloud records management system has the following problems. It has not been accompanied by a change in the legislative system and has not been exploited the benefits of cloud technology. In addition, it has not been considered for changes after system construction. To solve this problem, the contents of the Fourth Industrial Revolution should be reflected in the improvement of the legislative system and the long-term development strategy of the national archives system. A fundamental review of the records management system is also required, and in the process of e-government, the National Archives should act as a pan-government records management control tower.

In this paper, we classified the objectionable texts into four rates according to their harmfulness and proposed the hierarchical text rating system for objectionable documents. Since the documents in the same category have similarities in used words, expressions and structure of the document, the text rating system, which uses a single classification model, has low accuracy. To solve this problem, we separate objectionable documents into several subsets by using their properties, and then classify the subsets hierarchically. The proposed system consists of three layers. In each layer, we select features using the chi-square statistics, and then the weight of the features, which is calculated by using the TF-IDF weighting scheme, is used as an input of the non-linear SVM classifier. By means of a hierarchical scheme using the different features and the different number of features in each layer, we can characterize the objectionability of documents more effectively and expect to improve the performance of the rating system. We compared the performance of the proposed system and performance of several text rating systems and experimental results show that the proposed system can archive an excellent classification performance.

Destruction appraisal system improved with the enactment of the 1999 Public Records Management Act has the strategic concepts to prevent loss of important records with prohibiting the destruction in creation organization of records. But destruction appraisal carried out in record center realistically has the big difference with destruction appraisal system intended by Public Records Management Act. Therefore this article intends to explore the importance of destruction appraisal system through a review of the record appraisal system, and investigates operation status of destruction appraisal system in record center and operational issues. And it intends to explore scheme for practical application of destruction appraisal system based on actual cases of destruction appraisal which operates as a model.

Almost hot-Super Earths ($R_p$~1 to $4R_{earth}$ orbital period < 100 days) are around Sun-like stars. But our solar system does not have hot-Super Earth. Andre et al. 2015 has explained this phenomenon by that Jupiter blocks migration of super earth. We have found a multi-planetary system KOI-94 with exo-Jupiter and hot-Super Earth from NASA exoplanet archive data (http://exoplanetarchive.ipac.caltech.edu). In this study, within multi-planetary systems including hot-Super Earth, we compared those with and without exo-Jupiter using their host star and exoplanet parameters, such as metallicity [Fe/H], $T_{eff}$ and $R_*/R_p$.

A telemanipulator that reflects grasping force of the slave gripper to the human operator was implemented in order for manipulation to be more delicate and safe. An industrial robot gripper was used as the slave manipulator. The master manipulator was constructed to make it easy for a human operator to direct the slave and to feel the reflected gripping force. Reflected force was generated by the servomotor of the master. The force signal and position signals of the master and the slave was used to generate driving force signal. Basically position-position type control was used. Miner force feedback is added to improve the performance of the system. Implemented system was tested by colliding two fingers of the slave manipulator, and here switching was used to archive more fast and easy manipulation.

Historical archived traffic data management system enables a long term time-series analysis and provides data necessary to acquire the constantly changing traffic conditions and to evaluate and analyze various traffic related strategies and policies. Such features are provided by maintaining highly reliable traffic data through scientific and systematic management. Now, the management systems for massive traffic data have a several problems such as, the storing and management methods of a large volume of archive data. In this paper, we describe how to storing and management for the massive traffic data and, we propose methodology for logical and physical architecture, collecting and storing, database design and implementation, process design of massive traffic data.

In this paper, autonomous information exchange methodology is studied between IEDs using SOAP protocol based on XML and PtP communication to archive the safety and reliability of large-scale system operation. The SOAP protocol has the advantages in the independency Problem for operating systems, using language, platforms and the security problem because it is XML-based RPC protocol. Inference-based solution of the IED is designed as rule-based solution so that the IED internal status, the system status or the faulted zone can be inferred autonomously using the internal data as well as information data obtained from free information exchange among other IEDS, Also, it is designed so that the inference results and the operation information are transmitted to the above SCADA system, and determined autonomously whether the commands from the SCADA are executed or not. Finally, The inference-based solution of IED and information exchange system among IEDS is implemented using MS Visual C++ MFC, MS SOAP and MS XML. Availability and accuracy of the proposed methodology and the design is verified from diversity simulation reviews for typical distribution substation.

As the foundation for the Fourth Industrial Revolution, blockchain is becoming an essential core infrastructure and technology that creates new growth engines in various industries and is rapidly spreading to the environment of businesses and institutions worldwide. In this study, the characteristics and trends of blockchain technology were investigated and arranged, its application to the records management section of public institutions was required, and the procedures and methods of construction in the records management field of public institutions were studied in literature. Finally, blockchain technology was applied to the records management to propose an archive chain model and describe possible expectations. When the transactions that record the records management process of electronic documents are loaded into the blockchain, all the step information can be checked at once in the activity of processing the records management standard tasks that were fragmentarily nonlinked. If a blockchain function is installed in the electronic records management system, the person who produces the document by acquiring and registering the document enters the metadata and information, as well as stores and classifies all contents. This would simplify the process of reporting the production status and provide real-time information through the original text information disclosure service. Archivechain is a model that applies a cloud infrastructure as a backend as a service (BaaS) by applying a hyperledger platform based on the assumption that an electronic document production system and a records management system are integrated. Creating a smart, electronic system of the records management is the solution to bringing scattered information together by placing all life cycles of public records management in a blockchain.

The early history of foreign Protestant missionaries in Korea has begun in the late 19th century, when they came to work as professionals such as teachers, medical doctors, etc. as the nation opened its door to western culture with the fall of national isolationism. Their records are considered crucial resources that enable us to shed new light on modern Korean history, politics, economy and society beyond mere religious value. Despite the recognition of such historic value of early missionary resources, however, there has been serious lacking of a systematic attempt to develop policies and plans for making it easy to collect, preserve and access the resources. Up to date, the records of early Protestant missionaries, in diverse forms of mission reports, books, periodicals, personal diaries, letters and photos, are scattered around various places, including their home country churches, governments, libraries, museums, research institutes and homes. Therefore, this research aims at providing basic resources on the archival status of early Protestant missionaries in Korea, needed for developing a sustainable and systematic digital archive system, through the investigation of early foreign missionaries' resources and in-depth interviews of experts. The study covers the period of 1800s to 1910, that is from the beginning of Protestant missionaries entering into Korea until the start of the Japanese annexation in 1910.

PC grid computing is a paradigm of distributed computing that are collection the idle resource of numerous PCs to perform large-scale. As this way, created high performance resources use a large-scale computational application, also this paradigm studied new measurement in place of application using super computer. This paper suggests ORRS(Open Resource Registration System) that selects a adequate resource what application client want. This system register descriptions of resource that provide group, such as organization, party, team, PCs idle resource in open archive. Also, this system provide PC grid computing environment which is select suitable resource actively what application client want.
