Several fine particle-related policies in Northeast United States were investigated in support of the execution of special measures to improve air quality of Seoul Metropolitan Area (SMA). The definition of particulate matter (PM) in the Clean Air Act (CAA), components and procedures of Regional Haze Rule (RHR), and Air Quality Management (AQM) were reviewed. Several State Implementation Plans (SIPs) were also reviewed as the way to attain required air quality under the Clean Air Act. $PM_{2.5}$ attainment SIP of Maryland, 8-hr Ozone attainment SIP of New Jersey, and Regional Haze Rule attainment SIP of MANE-VU were analyzed in detail as case studies. We realized that "Special Measures for Air Quality Improvement in the Seoul Metropolitan Area" has many similarities with its US counterparts in terms of purpose, components, procedures, and implementation methods. US policies, however, have more advanced features, such as standardized procedures and methods, transparent guidelines, and stable relationship among federal/state/local governments and stakeholders, which would be helpful to improve air quality in SMA.

This study examines the meaning of the national education plan promotion background, focusing on the 5th Lifelong Education Promotion Basic Plan (2023-2027) and the 3rd 2023 Career Education Internalization Support Plan (2023-2027). The purpose of this study is to present future directions for lifelong education and career education. The research results indicate that The 5th Lifelong Education Promotion Basic Plan (2023-2027) and the 3rd 2023 Career Education Internalization Support Plan (2023-2027) have both been established to cope with the future social and educational environment; thus, it is necessary to realize them. For this purpose, concrete policy alternatives have been prepared. In modern society, it is vital for the state to promote basic plans related to education, particularly for developing and improving the education system. In this respect, when suggesting the direction of lifelong and career education, first, policies for social development and strengthening competitiveness are important. Second, policies are needed that respond to changes in jobs and occupations. Third, lifelong and career education are essential to ensure social inclusion and fairness. Fourth, lifelong and career education are vital in nurturing human resources for sustainable development.

Background and objective: Land vacancy is a persistent issue in most urban areas in the United States, yet few case studies have examined how vacant lots are used and the functions they serve in local communities. The purposes of this study were to provide a new revitalization planning and design proposal for the Durant-Tuuri-Mott (DTM) target area in the shrinking city of Flint, MI, USA, and to assess the final planning and design guideline through an analysis of vacant land redevelopment alternatives. Methods: For developing a revitalization planning and design guideline, this study developed several design modules with three main design themes. Then, landscape performance of the final design proposals was analyzed by three development scenarios, based on implementation level: 100%, 75%, and 50%. These development scenarios were based on the local context and different implementation budgets needed to adopt the proposed design modules. To generate a comprehensive development plan by optimizing design module allocation in the study area, this research employed a system-oriented approach, analyzing the existing cultural, natural, and built environments. A community participant process was adopted to collect stakeholders' opinions on future development. Results: By utilizing landscape performance metrics to quantify the environmental, social, and economic benefits, this study developed optimized development scenarios and a master plan for the reuse and redevelopment of existing vacant lots across DTM neighborhoods and analyzed the benefits of each. Conclusion: This research offers a flexible design method for balancing objectives in vacant land redevelopment that can be applied in other shrinking cities.

Purpose: It is to present the development direction of the overall 'disaster management implementation process' (tentative name) for the establishment of an effective 'safety management plan' by the government and local governments. Method: To this end, prior research on the 'safety management plan' was reviewed to derive common problems, and the direction of development was suggested by incorporating the 'disaster management execution process' (tentative name) that can solve these problems with the military's 'operational execution process'. Result: Common problems of previous studies can be supplemented through the 'disaster management performance process' (tentative name) presented by this researcher. Conclusion: Through the "disaster management implementation process" (tentative name), the government's basic ideology of disaster management can be finally achieved, "confirming that it is a basic mission of the state and local governments and allowing the people to live in a society that is safe from disasters."

Effective implementation of private subsidy projects requires comprehensive expertise in the aquaculture and construction sectors to be provided to private subsidy operators, local government officials and others involved in budget execution and settlement. Due to the strengthening of laws and systems related to the execution of state subsidies since 2015, the efficient implementation of private-sector grant projects has been difficult for delays in projects, cancellations, and conflicts with local governments from lack of prior awareness and understanding of related regulations. It is expected that the government will be able to activate the project by analyzing the current status and problems of each phase of project implementation for improving quality internalization of the project effects, as well as quantitative growth of the private sector subsidy project for environmentally friendly aquaculture development projects.

Nowadays, one of the important functionalities required from robot task planners is to generate plans to compose existing component services into a new service. In this paper, we introduce the design and implementation of a heuristic search planner, JPLAN, as a kernel module for component service composition. JPLAN uses a local search algorithm and planning graph heuristics. The local search algorithm, EHC+, is an extended version of the Enforced Hill-Climbing(EHC) which have shown high efficiency applied in state-space planners including FF. It requires some amount of additional local search, but it is expected to reduce overall amount of search to arrive at a goal state and get shorter plans. We also present some effective heuristic extraction methods which are necessarily needed for search on a large state-space. The heuristic extraction methods utilize planning graphs that have been first used for plan generation in Graphplan. We introduce some planning graph heuristics and then analyze their effects on plan generation through experiments.

The objective of this study is to provide information for improving the domestic particulate matter (PM) management. To achieve the study goal, we reviewed the past and current practice of PM management in the United States (US). Our review includes the assessment about the philosophical foundation and effectiveness of PM management, systematic program implementation to reach desirable PM conditions, and steady development of analytical tools including photochemical air quality models. We noticed that the current US PM management approach has improved annual $PM_{2.5}$ concentrations 22-48% in various parts of the US in the last 16 years. In addition, we analyzed strengths and difficulties in the past US PM management implementation. Based on the results of our analyses, we propose key elements to establish more effective domestic PM management in the future than now: steady investment in technological innovations and close-communications between local governments and the central government at various stages of PM management.

Publicly funded project centered urban regeneration projects have limitations in the implementation to fit the urban regeneration plan system under the 'Special Act on Promotion of and Support for Urban Regeneration.' Since urban regeneration projects have been promoted with publicly funded project centered uniform plans and non-planned systems as such, many problems have arisen such as increases in the time to establish plans such as many strategic plans and activation plans and resultant increases in social costs. Therefore, in this study, with a view to finding methodologies for the establishment and flexibilization of urban regeneration plan systems, the actual state of operation of the urban regeneration plan system was analyzed to find problems and present improvement plans for reestablishment of the South Korean urban regeneration plan system.
