Diverse Self-assembly Pathways in Nematic Compartment Network: Topological Percolation and Pathfinding.

The self-assembly of nematic molecules in microcompartments with unambiguously defined surface anchoring is well predictable and is likely to have a single stable topological structure. Here, in contrast, a confined nematic system comprising an array of microcompartments interconnected by channels is demonstrated, exhibiting diverse molecular assembly pathways leading to the formation of four types of topological structures and twelve different patterns randomly distributed. Intercompartment communication via channels plays a crucial role in the diversity of patterns and distributions.

Analysis of design-for-safety implementation factors in the Indonesian construction industry: A two-staged SEM-artificial neural network approach.

Despite the rapid growth of infrastructure development in Indonesia, work safety remains a major concern in construction projects. Design-for-safety (DfS) is a critical strategy to prevent work accidents. The implementation of design-for-safety is one of the most important strategies for preventing work accidents.

Correlation analysis of safety climate and construction productivity in South Korea.

The purpose of this study is to analyze the correlation between safety climate and productivity for actual construction projects. The safety climate of the case projects was analyzed using the Nordic occupational safety climate questionnaire for the participants of the projects, and the resources used for the main work were used to analyze productivity. Many researchers have concluded that if the safety climate in a construction business improves, the rate of human accidents decreases.

Worker safety perception analysis of South Korean construction sites.

The aim of this article was to measure the safety perception level of workers on a South Korean construction site and investigate safety problems using the Nordic occupational safety climate questionnaire (NOSACQ-50). The survey was carried out via the NOSACQ-50 with 175 workers from five South Korean construction companies to evaluate their perception level. The results were then compared with the NOSACQ-50 criteria.

Soil pH and electrical conductivity are key edaphic factors shaping bacterial communities of greenhouse soils in Korea.

Soil microorganisms play an essential role in soil ecosystem processes such as organic matter decomposition, nutrient cycling, and plant nutrient availability. The land use for greenhouse cultivation has been increasing continuously, which involves an intensive input of agricultural materials to enhance productivity; however, relatively little is known about bacterial communities in greenhouse soils. To assess the effects of environmental factors on the soil bacterial diversity and community composition, a total of 187 greenhouse soil samples collected across Korea were subjected to bacterial 16S rRNA gene pyrosequencing analysis.
