본 연구는 유보통합 추진 과정에서 유치원과 어린이집에 각각 적용되어 온 표준유아교육비와 표준보육비용의 이원화가 갖는 구조적 한계를 분석 하고, 이를 극복하기 위한 통합 표준비용 산정체계를 제안하는 것을 목적 으로 한다. 현재의 이원적 표준비용 체계는 재원 구조와 회계 기준의 차이 로 인해 동일 연령 영유아에게 제공되는 교육·돌봄 서비스의 조건과 수준 에 격차를 발생시키는 요인으로 작동하고 있다. 본 연구는 정책 문헌과 선 행연구 분석을 통해 표준비용 산정 전제와 비용항목 구성의 차이를 진단하 고, 통합 표준서비스모형을 기반으로 한 통합 표준비용 산정 원칙과 모형 을 제시한다. 분석 결과, 통합 표준비용은 단일 단가가 아닌 단일 산정 공 식으로 설계되어야 하며, 최소 비용이 아니라 질 보장형 적정 비용을 지향 해야 함을 확인하였다. 본 연구는 유보통합이 행정적 통합을 넘어 실제 서 비스 질의 통합으로 이어지기 위한 재정적 기준 설정에 정책적 시사점을 제공하였다.

This study designed an integrated certification system of ISO 50001 (energy management system) and ISO 14001 (environmental management system) with the goal of reducing corporate carbon emissions, and analyzed cases of applying it to actual management. In order to overcome the limitations of individual certification, an integrated operating system of the two standards was established, and a method was sought to maximize corporate energy efficiency and carbon emission management performance. After introducing the integrated system, the company under study reduced energy consumption by up to 30%, and carbon emissions were also significantly reduced. These results were achieved through internal process improvement and supply chain collaboration. This study suggests that the ISO integrated certification system can contribute to cost reduction and sustainable management, and proposes an implementation model that can be utilized in various industries in the future.

This study explores the critical interrelationship between component standardization and airworthiness certification in the context of military aircraft systems. As the complexity and technological integration of modern defense platforms increase, the alignment between standardized component frameworks and evolving airworthiness requirements becomes essential to ensure operational reliability, safety, and maintainability. The current defense acquisition and certification systems often operate in a decoupled manner, leading to duplicated testing, certification delays, and cost overruns. Through comparative analysis of national and international certification protocols (MIL-HDBK-516, NATO STANAG, EASA SIB), this paper identifies structural inefficiencies in managing non-standardized or partially certified components. Based on these findings, the study proposes a function-based integrated management system that enables data synchronization across standard parts databases, quality records, and certification requirements. The proposed framework consists of four core modules: (1) standard part information management, (2) quality assurance and test linkage, (3) certification support engine, and (4) lifecycle risk monitoring. The study also anticipates quantifiable improvements such as reduced certification time and improved audit traceability. The results provide practical and policy implications for enhancing the interoperability, reliability, and export competitiveness of domestic defense platforms.

As modern weapon systems become increasingly complex, the need for integrated management of component standardization and airworthiness certification has grown significantly. This study proposes a system-based approach to establish an integrated management framework that addresses inefficiencies, certification delays, and supply chain risks inherent in current military aircraft development processes. The research reviews the functional scope of component standardization and compares airworthiness certification systems across domestic and international defense sectors. It identifies limitations caused by the fragmented management of parts and certification processes, and proposes a digital platform that interconnects parts databases, configuration control, quality assurance, and certification modules. The framework incorporates AI and digital twin technologies to monitor and manage reliability across the entire life cycle of a weapon system. This study lays the foundation for enhancing the operational efficiency of national defense technologies, and contributes to strengthening the autonomy and global competitiveness of the Korean defense industry.

This study proposes a wind power generation system designed to enhance energy self-sufficiency in high-rise buildings by integrating internal and external airflow sources. In such structures, external wind generated by building height and form and internal airflow induced by the stack effect coexist but move in different directions. This study introduces a system that collects and integrates five types of wind into a single, unified flow. Wind speed data were calculated using meteorological datasets and stack effect equations, and a prototype was designed using Autodesk Fusion360. CFD simulations were conducted to determine the combined wind speed at the outlet. Based on the simulated results, expected power output was calculated using wind power equations. The building energy model was created in DesignBuilder and simulated in EnergyPlus using default office building settings. The predicted annual wind energy generation is approximately 962,022.85kWh, covering 11.73% of the building’s total annual electricity use. The study demonstrates the potential for wind-integrated high-rise designs to contribute to energy autonomy.

This study analyzed the structural performance of a microalgae-based lightweight ecological integration system for large-span structures to achieve carbon neutrality. To address the load problems of existing soil-based ecological systems, a lightweight system utilizing microalgae bioreactors was proposed, and structural performance was evaluated for four types of large-span structures: truss, arch, dome, and cable structures. Structural analysis results through finite element analysis showed that the proposed system achieved a 70% load reduction effect compared to existing systems, with structural performance improvements including 35-40% reduction in maximum deflection, 30-35% reduction in maximum stress, and 25-30% increase in natural frequency. Environmental performance analysis confirmed CO₂absorption capacity of 12-18 kg per m² annually and PM2.5 reduction effects of 15-25%. Economic analysis results indicated that benefits of 3.95-6.7 million KRW per year are generated for a 1,000 m²reference area, creating cumulative benefits of 179.75-227.5 million KRW over 25 years. Verification through the German BIQ House case confirmed CO₂reduction performance of 6 tons per year for 200 m², demonstrating the practical applicability of the system. This study presented the potential of an innovative ecological integration system that can ensure structural safety of large-span structures while simultaneously contributing to carbon neutrality.

The demand for automated diagnostic facilities has increased due to the rise in high-risk infectious diseases. However, small and medium-sized centers struggle to implement full automation because of limited resources. An integrated molecular diagnostics automation system addresses this issue by integrating small-scale automated facilities for each diagnostic process. Nonetheless, determining the optimal number of facilities and human resources remains challenging. This study proposes a methodology combining discrete event simulation and a genetic algorithm to optimize job-shop facility layout in the integrated molecular diagnostics automation system. A discrete event simulation model incorporates the number of facilities, processing times, and batch sizes for each step of the molecular diagnostics process. Genetic algorithm operations, such as tournament, crossover, and mutation, are applied to derive the optimal strategy for facility layout. The proposed methodology derives optimal facility layouts for various scenarios, minimizing costs while achieving the target production volume. This methodology can serve as a decision support tool when introducing job-shop production in the integrated molecular diagnostics automation system

Municipal landfill leachate (MLL) contamination in surface water is a critical global issue due to the high concentration of toxic organics and recalcitrants. The biological treatment of MLL is ineffective due to an elevated concentration of ammoniacal nitrogen, which restricts the production of the recalcitrant degrading laccase enzyme. In this context, integrating an external laccase-anchored carbon catalyst (LACC) matrix system with the microbial system could be an efficient strategy to overcome the drawbacks of conventional biological MLL treatment technologies. In the present study, the LACC matrix was synthesized by utilizing nanoporous activated carbon (NAC) functionalized ethylene diamine (EDA) and glutaraldehyde (GA) (GA/EDA/NAC) matrix for the anchoring of laccase. The maximum anchoring capacity of laccase onto GA/EDA/ NAC was achieved to be 139.65 U/g GA/EDA/NAC at the optimized anchoring time, 60 min; pH, 5; temperature, 30 °C, and mass of GA/EDA/NAC, 300 mg and was confirmed by Fourier transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), and X-ray Diffraction (XRD) analyses. Further, the mechanistic study revealed the involvement of covalent bonding in the anchoring of laccase onto the functionalized surface of the GA/EDA/NAC matrix. The adsorption isotherm and kinetics of laccase anchoring onto the GA/EDA/NAC matrix were performed to evaluate its field-level application. Subsequently, the sequential microbial system (I-stage bacterial treatment followed by II-stage fungal treatment) and III-stage LACC matrix system could effectively reduce the COD by 94.2% and phenol by 92.36%. Furthermore, the Gas Chromatography-Mass Spectrophotometry (GC–MS) and FT-IR analyses confirmed the effective degradation of organic compounds and recalcitrants by the integrated microbial and LACC matrix system. The study suggested that the application of the LACC matrix system has resulted in the complete treatment of real-time MLL by overcoming the negative interference of elevated ammoniacal nitrogen concentration. Thus, the integrated microbial and LACC matrix approach could be considered to effectively treat the MLL without any secondary pollution generation.
