“…Several previous studies have investigated the effectiveness of temperature and moisture control in improving compost quality. The results of these studies show that the use of temperature and moisture control technologies can have positive results in the context of composting 11,12 . Therefore, this research aims to further examine and provide a deeper understanding of the "Composter with Magic Compos Forward Reverse Design System" system as a potential method in improving the quality of compost produced.…”

Household waste management is an important concern in an effort to reduce the potential negative impact on public health due to organic waste generation. This study aims to analyze differences in compost maturation rates based on variations in the time interval of the turning process in Magic Compost, differences in compost maturation rates based on the type of organic waste, differences in C/N ratio, carbon content, and moisture content in compost, differences in nitrogen, phosphorus, and potassium levels in compost, and differences in temperature, pH, and color in compost based on household organic waste criteria. This research uses an experimental approach with a posttest without a control group design and applies a randomized complete group design (RAKL). The tool used is Magic Compost, which is equipped with a temperature and humidity controller. The results showed a significant difference in the rate of compost maturation based on the time interval variation of the turning process on Magic Compost (p value = 0.000). The best turning time interval is 12 hours. There was a difference in the rate of compost maturation based on the type of organic waste generated by households, with mixed waste compost maturing the fastest and rice/starch waste maturing the slowest (p value = 0.001). While there was no difference in the C/N ratio (p value = 0.202), there were significant differences in the carbon content and moisture content of the compost based on the type of organic waste (p values = 0.042 and 0.000). However, there was no difference in the nitrogen and phosphorus content of the compost (p value = 0.144 and p value = 0.663). There was a difference in potassium levels in the compost based on the type of organic waste (p value = 0.000). The temperature of the resulting compost showed no significant difference (p value = 0.000), but there were differences in the pH and color of the compost based on household organic waste criteria (p values = 0.048 and 0.007). This study provides important insights into organic waste management through composting with Magic Compost, which can be an effective solution for reducing the negative public health and environmental impacts caused by organic waste generation.

Fabric comfort is essential for maintaining both physiological and psychological well-being. The inherent low thermal conductivity and single-layer porous structure of traditional cotton fabrics compromise the body's cooling pathways and moisture management capabilities. Multifunctional fabrics, combining excellent thermal conductivity with superior moisture management, are emerging as potential candidates for the next generation of human thermal management textiles. In this study, a straightforward strategy for preparing dual-function wearable Janus-type fabric is proposed involving electrospinning thermoplastic polyurethane elastomer onto the surface of cellulose cotton fiber and concurrently loading thermally conductive boron nitride nanosheets. The prepared fabric exhibits excellent thermal and moisture management characteristics. It achieves a thermal conductivity of 0.307 W/mK, reducing overall thermal resistance to 10.62 K cm 2 /W. The practical indoor and outdoor tests in winter demonstrate that the surface temperature of the fabric in contact with human skin is 2.9 and 3.1 °C higher than that of the common fabric, suggesting its favorable heat dissipation ability. The construction of a dual wetting gradient allows for directed moisture transport within the fabric, with a water evaporation rate of 0.276 g/h. Additionally, its robust thermal stability and excellent mechanical properties ensure its reliability for prolonged wearable device applications.

Many buildings built before energy performance regulations are actually in a situation of thermal discomfort and energy inefficiency. The creation of intelligent environments is moving towards new opportunities, based on real-time monitoring and on the development of sensors and technologies. Furthermore, building automation and electronic systems standards enable interoperability and interconnection between control devices and systems. The application of soft computing has significantly improved the energy efficiency; however, it requires prior assessment to design the automation functions. Temperature, humidity, air quality and energy consumption are the most commonly measured parameters, but their relationships with other operational variables such as occupancy or some building states remain as a research challenge. This article presents a methodology to develop the automation of a large existing public building. This methodology consists of two stages: 1. Assessment and diagnosis to set appropriate functions, using EN ISO 52120-1 and EN 50,090 for open communication networks, and EN ISO 52120-1 to assign the technical building management. 2. System control deployment of low-cost and low-consumption input and output devices. It has been proven that it is possible to effectively automate an obsolete building with a low-cost, open-source system that can be easily applied to other buildings.
