The purpose of this paper is to analyze the free economic zone policy from the viewpoint of Policy Science. because of insufficiency on policy science of the previous researches for the free economic zone. So Trying on free economic zone policy from the viewpoint of policy science, the paper is shown the new proposal for free economic zone policy. For this trying, this paper used to the viewpoint of policy science; (1) the system of policy(policy process, policy content(pattern)), (2) the policy implementation(local government-central intergovernmental management). In the end, beyond the previous research on the free economic zone policy, shown on not only new viewpoints on the free economic zone, but also, the solutions of practical implementation for free economic zone on the free economic zone.

Recently, as local heavy rains occur frequently in a short period of time, economic and social impacts are increasing beyond the simple primary damage. In advanced meteorologically advanced countries, realistic and reliable impact forecasts are conducted by analyzing socio-economic impacts, not information transmission as simple weather forecasts. In this paper, the degree of flooding was derived using the Spatial Runoff Assessment Tool (S-RAT) and FLO-2D models to calculate the threshold rainfall that can affect human walking, and the threshold rainfall of the concept of Grid to Grid (G2G) was calculated. In addition, although it was used a lot in the medical field in the past, a quantitative accuracy analysis was performed through the ROC analysis technique, which is widely used in natural phenomena such as drought or flood and machine learning. As a result of the analysis, the results of the time period similar to that of the actual and simulated immersion were obtained, and as a result of the ROC (Receiver Operating Characteristic) curve, the adequacy of the fair stage was secured with more than 0.7.

최근 들어 U-City 구축 사업을 수행하고 있는 대다수의 지자체에서는 U-City건설지원법에서 규정하고 있는 U-도시기반시설의 서비스 모델을 정립하고 체계화 하기위해 노력하고 있다. 그 중 공간정보 수요가 높은 도로, 상 하수도 시설물은 국토해양부의 주관하에 90년말부터 현재까지 매칭펀드 사업을 통해 DB 및 시스템을 구축하도록 유도해 왔다. 그러나 정부차원의 이러한 사업이 지자체 지리정보 담당부서와 지하시설물 관리 담당 공무원들 중심으로 단순히 공간정보의 조회 및 편집차원에서 추진되고 있어 활용에 대한 한계가 발생하고 있다. 본 연구는 국토해양부에서 주관하고 있는 '지능형 도시 지하시설물 관리 기술 개발' R&D 사업을 통해 이러한 한계를 극복하고 기존 상 하수도 단위시스템에서 제공하는 조회 및 편집기능이외에도 USN 및 RFID를 적용하여 활용할 수 있는 지능화된 지하시설물 관리업무를 도출하고, 기존 상 하수도 단위시스템과의 연계 모델을 제시하고자 한다.

많은 개발자가 참여하는 대형 소프트웨어 시스템 개발의 효율성 증대를 위해서는 컴포넌트 간 인터페이스의 효과적인 관리가 필수적이다. MDMS는 컴포넌트간의 인터페이스 정의 및 변경 이력 관리, 인터페이스 기술서 자동 생성, 소스 코드 자동 생성 등의 기능을 제공하는 도구이다. 한화탈레스는 1998년 MDMS를 처음 개발하여 적용한 이후 다양한 국방 소프트웨어 시스템 개발에 적용하여 소프트웨어 개발 생산성 향상에 효과를 보았다. 하지만, MDMS를 다양한 프로젝트에 적용하는 과정에서 최초 개발시 고려하지 못했던 여러 문제점 및 한계를 발견하였다. 이러한 문제점 및 한계는 다양한 프로젝트의 특성 지원 미흡, 형상관리 및 유지보수 문제, 프로젝트 간 메시지 재사용 미지원, 취약한 보안 등 이다. 본 논문에서는 이를 해결하기 위하여 네가지 개선방안을 제시한다. 첫 번째, 다양한 프로젝트에 적용이 가능한 유연한 SW 구조로 개선해야 한다. 두 번째, 통일되고 일관된 형상관리와 함께 전담 개발 및 유지보수 조직이 필요하다. 세 번째, 프로젝트간 메시지의 재사용 지원을 위한 방안으로 프로젝트 별 MDMS 운용이 아닌 통합된 MDMS의 운용이 필요하며, 그를 통하여 다른 프로젝트의 인터페이스 정의를 상호 참조할 수 있는 구조를 적용해야 한다. 마지막으로, 외부 협력업체와의 협업을 위한 보안 대책을 수립하고, 관련 보안 기능을 지원하여 사외의 협력업체의 개발자가 직접 MDMS에 접속하여 개발할 수 있도록 개선해야 한다.

Currently, an implementation plan of administrative information dataset record management has been prepared; however, analyzing the specificity of various administrative information systems and preparing a reasonable level of management reference table by applying about 1.3% (EA portal registration system: 16,199, consulting system: 214) has its limitations. This study started by recognizing the importance of the records management environment in administrative information datasets. Based on the described information, the current records management environment was analyzed by dividing the six areas of the management reference table of the picture archiving and communication system (PACS) into three groups. Thus, a systematic environmental improvement model was proposed, enhancing the effectiveness of dataset records management in the field. Although there is a limitation in analyzing one of the dataset records management environments of various institutions, it is intended to help broaden the horizons of records management research.

CCC-r chart is effective for high-quality processes with a very low fraction nonconforming. The values of process parameters should be estimated from the Phase I sample since they are often not known. However, if the Phase I sample size is not sufficiently large, an estimation error may occur when the parameter is estimated and the practitioner may not achieve the desired in-control performance. Therefore, we adjust the control limits of CCC-r charts using the bootstrap algorithm to improve the in-control performance of charts with smaller sample sizes. The simulation results show that the adjustment with the bootstrap algorithm improves the in-control performance of CCC-r charts by controlling the probability that the in-control average number of observations to signal (ANOS) has a value greater than the desired one.

As construction projects increase their complexity, variety, and scale, various recognition applications (such as RFID, bar-code etc.) have been tried for managing material effectively in construction projects. However, existing recognition applications for construction material management have some limitations that cause additional works (such as attaching RFID tag), additional cost (labor cost, recognition device cost, etc.), and cognitive impairment of workers. Therefore, this study proposed a character recognition technology as an alternative of previous recognition technologies such as RFID, bar-code, etc. The technical feasibility of proposed technology was validated by three recognition tests. Additionally, this study proposed code the structure to manage materials using the character recognition technology. The effects of character recognition technology are presented by comparing with existing RFID-based logistics processes.
