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.

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.

최근 들어 로봇 작업 계획기에 요구되는 중요한 기능 중의 하나가 이미 존재하는 컴포넌트 서비스들을 결합하여 새로운 서비스로 조합해낼 수 있는 계획 기능이다. 본 논문에서는 이러한 컴포넌트 서비스 조합을 위한 커널모듈로 개발된 휴리스틱 탐색 계획기인 JPLAN의 설계와 구현에 대해 설명한다. JPLAN은 효율적인 상태 공간 탐색을 위해 지역 탐색 알고리즘과 계획 그래프 휴리스틱을 이용한다. 본 논문에서 제안하는 지역 탐색 알고리즘인 EHC+는 FF 등의 상태 공간 계획기에 적용되어 높은 효율성을 보인 Enforced Hill-Climbing (EHC)을 확장한 것이다. EHC+는 EHC에 비해 소량의 추가적인 지역 탐색을 필요로 하지만 목표 상태까지 전체 탐색 양을 줄일 수 있고 더 짧은 계획을 얻을 수있다. 또한 본 본문에서는 대규모 상태 공간 탐색에 필수적인 효과적인 휴리스틱 추출 방법을 제안한다. 본 논문에서 제안하는 휴리스틱 추출방법은 Graphplan에서 계획 생성을 위해 처음 제안된 계획 그래프를 이용한다. 본 논문에서는 이러한 계획 그래프 기반의 다양한 휴리스틱들을 소개하고, 이들이 계획 생성에 미치는 효과를 실험을 통해 분석해본다.

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.

최근 전국적으로 많은 지자체들이 '도시재생특별법' 개정과 '도시재생 선도지역', '도시재생 뉴딜정책'의 추진으로 도시재생 사업을 추진하고 있지만, 공모사업 중심의 도시재생사업은 '도시재생특별법'에 의한 도시재생 계획체계에 맞게 추진하기에는 한계가 있다. 이처럼 공모사업 중심의 획일적인 계획과 비 계획체계에 의한 도시재생사업 추진되고 있어 많은 전략계획과 활성화계획 등 계획수립 소요시간 증가와 이에 따른 사회적 비용증가 등 많은 문제점을 야기하였다. 이에 본 연구에서는 도시재생 계획체계 정립 및 유연화 등의 방법론을 모색하고자 함을 목적으로 도시재생 계획체계의 운영 실태를 분석하여 문제점을 분석하고 개선 방안을 제시하여 우리나라의 도시재생 계획체계 재정립 등의 방안을 연구하고자 한다.
