The current Private 5G use procedure goes through the step of application examination, use and usage inspection, and can be divided in to application, examination step as a procedure before frequency allocation, and use, usage inspection step as a procedure after frequency allocation. Various types of documents are required to apply for a Private 5G, and due to the document screening process and radio station inspection for using Private 5G frequencies, the procedure for Private 5G applicants to use Private 5G is complicated and takes a considerable amount of time. In this paper, we proposed Frequency Allocation Process for Private 5G using a blockchain platform, which is fast and simplified than the current procedure. Through the use of a blockchain platform and NFT (Non-Fungible Token), reliability and integrity of the data required in the frequency allocation process were secured, and security of frequency usage information was maintained and a reliable Private 5G frequency allocation process was established. Also by applying the RPA system that minimizes human intervention, fairness was secured in the process of allocating Private 5G. Finally, the frequency allocation process of Private 5G based on the Ethereum blockchain was performed though a simulation.

The wave of globalisation initiated by marketisation has increasingly penetrated into all sectors across the world, accordingly, the health & hospital service sector could not be made no escapes, and it currently faces the order of more marketised competition more than ever. Traditionally, the characteristic of the hospital services in the UK has considered as a model of social provision by government. However, contrary to our knowledge, the sphere of the hospital service in the UK has already been immersed in by the marketisation, in which the private actors have been embedded in order to tweak the activities of the hospital service with in the European Union. As the methodology of this research, the qualitative analysis, namely the interview with some doctors in Surgery, NHS Trusts staffs and relevant specialists in has been performed on April to May, 2003. And on the other hand, the various documents related to its service have been analysed. Thus, this paper will review the characteristics of the health service sector in the UK. In doing so, it will illuminate what would be the structural factors derived from its existing system, as a result, it will shed light on how the UK government makes an effort to resolve the problematic situation by reviewing the policy direction of Foundation Hospital proposed recently. In the next stage, it will analyse how all elements consist of the hospital management in the UK has been adjusted and be likely to be changed within Europe. More specifically focuses on how the private hospital service has been managed and related with the activities of its public hospital service-NHS Trusts. Also, under the circumstance, what private health insurance companies function will be studied. In conclusion, it will be concluded that what will be the implication of Korean hospital service market so as to correspond to globally open market by WTO. Now the UK health service system has faced a turning point of becoming more health care market internally and externally pressed by global and regional factors. Thus it is meaningful to scrutinize how a key part of social provision in the health care market system tends to adjust to globally marketised regulation.

Electronic records are generated not only in public sector but also in private sector. Records will be used across the public-private boundary. The Certified e-Document Authorities(CeDAs) may keep electronic documents in private sector for preservation and evidence, like the official Record Management Systems for Public sector. A CeDA is the Trusted Third Party (TTP) as a business to be entrusted and proof interchanging documents between parties. This CeDA system could be sustainable only if the CeDA earn the enough sales through enough uses. And yet, all the eight CeDA companies have not had enough users. How to utilize CeDAs is one of the hot issues in this area. In this paper, We analyze the threat to trustworthiness of CeDA due to payment of only one party among others, and describe the difficulty in use of CeDA for an individual user. These things make CeDAs cannot have enough users. To do address these, We expand the boundary of relevant parties for a document, present a delegate-establishing option under a joint name, show the needs of identifying and notifying minimum relevant parties, and suggest the proxy parties to help the individual users.

Finance Companies are operating a security solution such as E-DRM(Enterprise-Digital Right Management), Personal information search, DLP(Data Loss Prevention), Security of printed paper, Internet network separation system, Privacy monitoring system for privacy leakage prevention by insiders. However, privacy leakages are occurring continuously and it is difficult to the association analysis about relating to the company's internal and external distribution of private document. Because log system operated in the separate and independent security solutions. This paper propose a systematic chains that can correlatively analyze business systems and log among heterogeneous security solutions organically and consistently based on security documents. Also, we suggest methods of efficient detection for Life-Cycle management plan about security documents that are created in the personal computer or by individual through the business system and distribution channel tracking about security documents contained privacy.

Recently, XML is used to describe details of service and contents for various fields such as IPTV and digital broadcast services because of it's high readability and extensibility. TV-Anytime's schema and delivery protocol have been especially adopted as basic standards for them, and extended to include their own private functions. However, XML describes documents using text-based method, and this causes to create big documents rather than traditional methods. Therefore, many encoding algorithms have been proposed to reduce XML documents like EXI, BiM, GZIP and fast-info set etc. Although these algorithms shows efficient compression effects for XML documents, but they can't avoid fragmentation degradation during encapsulation steep. This paper proposes an efficient encapsulation scheme of TV-Anytime to avoid fragmentation degradation of encoding effect using common string tables.

Public and private schools have close relationship with education-related organizations and they have exchanged formal documents to communicate each other. Introducing the XML/EDI used in electronic-commerce to the education web will make a great benefit for decreasing affairs in educational administration. In this paper, we implement a document management system using XML/EDI. This system makes it possible to treat documents which are not supported in current education-information-exchange system and can be added to the current system without any additional modification. We analyze the documents used in the current system and implement new types of tags suitable for education web. In addition, we difine new documents and DTD using only XML without any application software. This will have effects on reducing teacher's administrative work and enable teachers to concentrate on their teaching.

Many people have been building HTML documents due to rapid spread and growth of web. However, HTML has limits in satisfying user's requirements, so that XML has emerged. In this paper, we design and implement student information management programs and presentation methods for maintaing the general student life archives and the analysis of results of examinations using XML and web browser. We define a XML DTD for general student life archives, and build XML documents. A private student life archive is printed from XML documents on the web using XMLDOM, DATA-BINDING, and XSL. Also, personal items and a roll book of a class can be printed and searched. In order to analyze the result of examinations we define DTD and build XML documents according to the DTD.

The police substation includes work spaces for civil services, interviews, and meetings, etc, and private spaces for rest, showers and cafeterias and so on. Since a large number of rooms for each function should be installed in a relatively small building, it is important to develop an area standard for efficient space organization in consideration of the functional characteristics and usage patterns of each space. The purpose of this study is to suggest the way for improving the area standards for spaces in police substation based on the results of existing standards analysis and case study. For this objective, architectural documents of 161 police substations built after 2013 in Korea were comparatively analyzed. Sixteen of these facilities were selected for field survey and investigated how the workspace and private area were organized and used. The results of investigation showed that there were a number of problematic cases, such as spaces not installed or insufficient, spaces used for two or more functions, spaces installed even though they are not included in the standards. It was mainly due to the fact that several important spaces which had been installed in most police substations were not included in the existing standards. The ways for improvement were suggested like following four points: (1) Modifying the criteria for classifying facility size, (2) Modifying the lists of the required spaces, (3) Specifying the basis of calculation for each space in detail, and (4) Differentiating the way to organize spaces according to the facility size.

The methods of selection through observations and recommendations were introduced in the process of recruiting new students for the science education institutes for the gifted attached to 25 universities recently. This paper itemized the methods of screening through observations and recommendations. This paper also analyzed the problems with the methods and attempted to create plans for their improvement. The methods of selection through observations and recommendations led to the positive results that students' usual activities and attitudes in the classroom were reflected on the evaluation and that the cost of their private lessons was also reduced. However, the methods showed a few problems that need to be corrected. We point out problems occurring with examining their documents for submission and interviews. It was not easy to grade candidates' gifts, creativity, potential and development within the contents of the documents and the limited time of conducting interviews. On the plans for the developments of the implemented methods of selection through observations and recommendations, we have several suggestions. The chances for teachers' in-service training of learning the methods of selection through observations and recommendations need to be expanded. The interview needs to be enhanced and to have the same weight as the document screening. To secure the continuity of the education for the gifted, the clear guidelines from the Ministry of Education, Science, Technology along with the cooperation of the education institutes for the gifted are essential.

Using the 2001 Family Income and Expenditure Survey micro-data, this study analyses the anti-poverty effectiveness of public and private income transfers. In this study, the anti-poverty effectiveness of income transfers is summarized in two ways; 1) the poverty reduction effect of the income transfers, and 2) the poverty reduction efficiency of the income transfers. The poverty reduction effects are measured with several poverty indices including the head-count ratio, poverty gap, and Sen index. Using Beckerman's model, this study also analyses the poverty reduction efficiency of income transfers. This analysis documents substantial differences in the anti-poverty effectiveness of public and private income transfers. Although the private income transfers contribute more to reduce the head-count poverty ratio and Sen index than public income transfers, their differences are significantly reduced after the enactment of National Basic Livelihood Security Act. The results also reveal that the anti-poverty effectiveness of public and private income transfers vary by the types of families. In families headed by elderly and working aged, private income transfers have more anti-poverty effectiveness. But, public income transfers contribute more to reduce poverty than private income transfers among families headed by single adults with children. The results of this study suggest that recent changes in anti-poverty policies in Korea have been strengthened the Government's responsibility. And more importantly, to effectively reduce poverty among the poor families, anti-poverty polices must be designed to consider different family types.
