    This study examines improvement strategies for the Building Energy Management System (BEMS) evaluation framework within the G-SEED certification system based on a literature review. The purpose of this research is to encourage the adoption of BEMS as a means of reducing building energy consumption and carbon emissions. To achieve this, BEMS-related assessment items in G-SEED were reviewed in comparison with those in BREEAM and LEED, and a systematic analysis of domestic research literature published over the past five years was conducted. The results indicate that the current G-SEED system assigns a very low score for BEMS installation, suggesting the need to reconsider its weighting in relation to installation costs and potential energy-saving effects. In addition, system automation-related items dispersed across the certification framework should be integrally reorganized into BEMS-related categories to support coordinated control of building systems. Furthermore, the indirect reflection of BEMS control logic through demand control strategies and the allowance of dynamic energy simulation methods should be considered, with careful attention to compatibility with existing evaluation tools. Finally, providing additional credits for the selective implementation of BEMS-related systems may enhance practitioners’ awareness and promote market activation. - COLLAPSE

    This study investigated cold-induced vasodilation (CIVD) responses in the fingers of North Korean defectors, focusing on generational differences between the Jangmadang (JMD) and Arduous March generations (AMG). Twenty-four subjects (14 males, 10 females; 14 JMD, 10 AMG) participated in a 60-min trial, which consisted of 10-min rest, 30-min cold water immersion at 4.0 ± 0.1°C, and 20-min recovery. CIVD parameters including minimum finger temperature (Tmin), onset time (tonset), maximum finger temperature (Tmax), mean finger temperature (Tmean), amplitude, frequency, and resistance index of frostbite (RIF) were analyzed. AMG showed significantly higher Tmax compared to JMD (14.2 vs. 11.9°C, P = 0.049), while other CIVD parameters showed no significant differences. Notably, all subjects achieved the maximum RIF score of 9 points, indicating superior local cold tolerance compared to general population norms (5-6 points). Body mass index, body weight, and waist circumference showed significant positive correlations with Tmin (r = 0.574, 0.420, and 0.566, respectively) and negative correlations with tonset. AMG reported significantly lower finger cold sensation at 50 min (P = 0.008). These findings suggest that both generations possess exceptional peripheral cold tolerance, with AMG demonstrating enhanced vasodilatory capacity, likely attributable to prolonged cold exposure during formative years. This study provides foundational evidence for understanding human cold adaptation mechanisms under extreme environmental conditions. - COLLAPSE

    As South Korea pursues its carbon neutral goals, interest in sustainable construction materials and energy-efficient buildings continues to grow. Wood, known for its low carbon footprint and strong thermal insulation, has emerged as a promising alternative. Since 2018, Jinju City in Gyeongsangnam-do has promoted itself as a “wood-friendly city,” encouraging the use of wood in public buildings. This study examines the energy efficiency and user satisfaction of five wooden public buildings in Jinju, mainly used as local community facilities. The research consists of two stages: a quantitative comparison of energy consumption with similar non-wood buildings, and a qualitative evaluation through on-site observation and interviews. Energy performance was assessed using Energy Use Intensity (EUI, kWh/m²·yr). The results indicate two key findings. First, smaller wooden buildings tend to show higher and more variable EUI values, suggesting that differences arise from operational characteristics rather than the inherent properties of wood. However, limited sample size and data availability highlight the need for further research. Second, satisfaction surveys involving 20 users and managers revealed that wooden buildings offer higher psychological comfort and a warmer atmosphere than concrete buildings, though concerns remain regarding pests, humidity, fire safety, and maintenance. The study suggests that technical improvements, stable funding, and consistent policy support are essential to ensure the sustainable development of wooden public architecture. - COLLAPSE

    Contemporary design practice requires integrative solutions beyond single disciplines. This study evaluates a Convergence Design studio integrating Product Design (PD) and Visual Design (VD). The model structures competencies using a Knowledge–Skill–Attitude (K–S–A) framework. A team-based course delivered over a semester was implemented with senior undergraduate design students. Students were categorized by prior background: PD-dominant, VD-dominant, or Balanced. Mixed methods combined K–S–A pre/post surveys with instructor and expert evaluations. Overall convergence competencies improved across CD-K, CD-S, and CD-A. Attitude—communication, role negotiation, and coordination—most strongly drove integrated outcomes. Balanced teams performed well, but mixed teams also succeeded when collaboration attitudes were strong. Students developed “mutual translation” between product structure and visual narrative, informing studio design. - COLLAPSE

    This study developed an agricultural simulator that integrates a digital twin and a metaverse-based 3D virtual environment, and quantitatively verified its effectiveness by applying an XGBoost (Extreme Gradient Boosting)-based regression prediction model. Existing machine learning (ML)-based agricultural prediction research has tended to focus on improving prediction accuracy, but there has been a relative lack of a decision support structure that integrates synchronization with actual operating environments, scenario-based repeated experiments, and user interaction. Therefore, this study proposes an “agricultural metaverse simulator” that combines (1) building a digital twin model based on actual greenhouse data, (2) real-time visualization and interaction in a metaverse environment, and (3) integration of an XGBoost-based growth prediction model. The data were collected from the Rural Development Administration’s publicly available tomato data and data from three experimental greenhouses, and a total of 18 variables were configured: seven inputs (environment/control) and 11 outputs (growth/production). Preprocessing ensured reproducibility by specifying unit unification, missing value handling, and outlier correction (IQR: Interquartile Range) criteria. Model performance was evaluated using Root Mean Squared Error (RMSE) and Coefficient of Determination (R²), and results were presented by greenhouse unit (farm_code). Furthermore, the effectiveness of the simulator was rigorously verified through statistical significance tests (paired-samples t-tests and, when necessary, nonparametric tests) for differences between simulation results and field measurements. - COLLAPSE

    This study examines the validity of the constant thermal resistance applied to enclosed air cavities thicker than 10 mm in the Korean Energy Saving Design Standard for PV-backed building envelopes. Thermal–fluid simulations were performed using ANSYS CFX with various combinations of turbulence and radiation models. The Generalized k–ω and Discrete Transfer model combination showed the most stable convergence and was selected for analysis. Cavity thicknesses from 10 to 100 mm were investigated to evaluate thermal resistance and airflow characteristics. The results indicate conduction-dominated heat transfer below 20 mm, laminar natural convection at 30 mm, and turbulent natural convection above 40 mm. Although the thermal resistance increase converges in the turbulent regime, it does not become constant. At 100 mm thickness, the thermal resistance increased by about 52% compared with the fixed standard value, suggesting the need for a complementary evaluation approach to better reflect the thermal behavior of thick PV air cavities. - COLLAPSE
