The information systems of the Korea Postal Service are developed not for integration based on strategic purposes but for improvement of low-level business processes within each functional unit. Hence. the as-is level of the information systems is very insufficient for information integrity, and also shows substantial gaps. when compared to recent advances in information envconment such as internet, electronic govemment and so on in this study we suggest the design of the integrated platform to achieve integrity of postal service and banking servive. After briefly addressing the issues on information systems of the Korea Postal Service. we provide the framework of the integrated platform and action plan. We believe when this framework is put into use. It can contribute to competitive performance by giving the integrity and consistency in implementing infomation systems of the Korea Postal Service.

In this paper, we analyze experimental results by applying the PHILS model to a lab-scale superconducting current limiter system for its actual application in medium-voltage direct current (MVDC) systems. Superconducting current limiters exhibit effective current-limiting performance in circuit breaker operations, particularly in limiting large fault currents within a short period, addressing the challenges posed by the increasing use of renewable energy and the integration of DC medium-voltage distribution systems. The development of such superconducting current limiters faces various technical and cost disadvantages, especially when applying a medium-voltage 35kV level system, which is intended for future introduction. The proven lab-scale superconducting current limiter system and the PHILS model are combined and integrated into the actual system. Our plan involves analyzing the limiter's performance, assessing its impact on the system, and preparing for its application in future medium-voltage systems. Utilizing RTDS, a simulation was conducted by connecting actual scaled-down equipment and systems, with the analysis results presented.

This paper presents advancement in multi- unmanned aerial vehicle (UAV) cooperative area surveillance, focusing on optimizing UAV route planning through the application of genetic algorithms. Addressing the complexities of comprehensive coverage, two real-time dynamic path planning methods are introduced, leveraging genetic algorithms to enhance surveillance efficiency while accounting for flight constraints. These methodologies adapt multi-UAV routes by encoding turning angles and employing coverage-driven fitness functions, facilitating real-time monitoring optimization. The paper introduces a novel path planning model for scenarios where UAVs navigate collaboratively without predetermined destinations during regional surveillance. Empirical evaluations confirm the effectiveness of the proposed methods, showcasing improved coverage and heightened efficiency in multi-UAV path planning. Furthermore, we introduce innovative optimization strategies, (Foresightedness and Multi-step) offering distinct trade-offs between solution quality and computational time. This research contributes innovative solutions to the intricate challenges of cooperative area surveillance, showcasing the transformative potential of genetic algorithms in multi-UAV technology. By enabling smarter route planning, these methods underscore the feasibility of more efficient, adaptable, and intelligent cooperative surveillance missions.

This study aims to identify the methods of implementation for the 'National Research Foundation of Korea Open Access 2021(Plan)'. This study covers the methods of implementation in the three following core items: 1) developing the details on the amount, method, and procedures of APC support; 2) proposing methods for facilitating the transition of domestic Korean academic journals to open access journals; and 3) developing methods of entrusting papers to open access repositories. APC support should be guaranteed at a reasonable level. The average or median of APC values for the previous three years will be applied to set the upper limit for support each year. APC support will be provided when the paper is published to open access journals or transitioning journals to open access. Hybrid journals or dual access journals are not included. Support for open access publishing of academic journals in Korea during the transition period will be available for open access journals that have registered for CCL in KJCI or journals that have submitted their application for transitioning to open access. Publishing in hybrid, dual access or subscription-based journals must be accompanied by items related to copyright such as embargo. Research results will be used for the detailed implementation plan of 'NRF OA2021 (Plan)'. They will serve as the base data for the rapid, stable, and sustainable implementation of open access policy in NRF, addressing the Korean domestic academic journal publishing environment and the field of international academic communication.

This thesis is intended for addressing issues of the local expropriation committee system by drawing the policy suggestion through theoretical considerations on the land expropriation system of the UK and of the US, and for finding a plan to improve the system by focusing on the examples of land expropriation of local governments. The US' Takings utilize a public hearing and the jury system. When property is expropriated through eminent domain, stakeholders and citizens share the necessity of the expropriation and its awareness through a public hearing, and project institutes (administrative organizations) file a lawsuit to a law court to exercise takings. In the case of Compulsory Purchase in the UK, the system should be based on laws established by the Parliament, and the resolution to use CPO is also decided by district councils. So the system is able to prevent power abuse. As a plan to improve the land expropriation committee of local governments, it is necessary ${\triangle}$ to enhance the professionality of the local land expropriation committee, ${\triangle}$ to expropriate lands by the analysis of land type, and ${\triangle}$ to come up with alternative measures to prevent the rights of the expropriated.

Not all sciatica-like manifestations are of lumbar spine origin. Some of them are caused at points along the extra-spinal course of the sciatic nerve, making diagnosis difficult for the treating physician and delaying adequate treatment. While evaluating a patient with sciatica, straightforward diagnostic conclusions are impossible without first excluding sciatica mimics. Examples of benign extra-spinal sciatica are: piriformis syndrome, walletosis, quadratus lumborum myofascial pain syndrome, cluneal nerve disorder, and osteitis condensans ilii. In some cases, extra-spinal sciatica may have a catastrophic course when the sciatic nerve is involved in cyclical sciatica, or the piriformis muscle in piriformis pyomyositis. In addition to cases of sciatica with clear spinal or extra-spinal origin, some cases can be a product of both origins; the same could be true for pseudo-sciatica or sciatica mimics, we simply don't know how prevalent extra-spinal sciatica is among total sciatica cases. As treatment regimens differ for spinal, extra-spinal sciatica, and sciatica-mimics, their precise diagnosis will help physicians to make a targeted treatment plan. As published works regarding extra-spinal sciatica and sciatica mimics include only a few case reports and case series, and systematic reviews addressing them are hardly feasible at this stage, a scoping review in the field can be an eye-opener for the scientific community to do larger-scale prospective research.

The main purpose of this investigation is to make up for the limitations of parcel addressing and to seek the application plan of cadastral triangulation point to effective installation of national index numbers. The test-bed has been constructed at the mountainous area located in Nowon-gu, seven cadastral triangulation points within the test-bed was directly applied to this investigation. Each points have been firstly converted from a plane rectangular coordinates to a single plane rectangular coordinates (UTM-K). To verify positioning results achieved from these points, a single plane rectangular coordinates through the Network-RTK was considered. With regards to verification result, maximum coordinate shift was revealed by 6 cm, this level of difference can be satisfied to Article 7, paragraph 2 "the regulation for National Index Number". This means that coordinate transformation applied with cadastral triangulation points can achieve the sastisfied result without local surveying. And also, remarkable effects have been created in terms of financial effectiveness and safe preservation of cadastral triangulation points due to the omission of local surveying.

This paper examines the comprehensive problems concerning education and policy in applied music through the foundation of academy. Today, we can receive information that developing popular music of actual domain is arrived at considerable level. However, a theoretical base remains lacking and this continues to impede development. I separated the education to branch and researched intensively because the problems of these are very serious and important matter. I proceeded research by mean of primary improvement that classified into two ways. First is education. I reviewed problems in various subjects, including curriculum, textbook, teacher certification examination and the lack of research and books available. Second is policies. I mainly considered the NCS which is a recent debated topic. Finally, we suggest the establishment of a research institute as a solution for these subjects. In this paper, we propose solutions such as the establishment, purpose, as well as the necessities and roles of academy. In conclusion, we propose suggestions for addressing problems associated with current policies and ways of developing popular music.
