Summary
The Trust Leading Indicator (TLI) and Proactive Leading Indicator (PLI) show promise for assessing safety culture in Korean industries. These indicators correlate with safety climate, behavior, and risk perception, supporting their global applicability.
Area of Science:
- Occupational Health and Safety
- Industrial Psychology
- Risk Management
Background:
- Explores the applicability of the Trust Leading Indicator (TLI) and Proactive Leading Indicator (PLI) in Korean industries.
- These indicators are part of the Vision Zero initiative to promote a prevention culture.
- Examines relationships between TLI/PLI and safety climate, safety behavior, risk perception, and accident experience.
Purpose of the Study:
- To assess the utility of TLI and PLI as leading indicators of safety culture in Korean manufacturing.
- To determine the correlation between TLI/PLI and established safety culture variables.
- To investigate differences in TLI/PLI based on workers' accident experience.
Main Methods:
- Surveyed 630 workers from 12 subcontractors at a large Korean manufacturing plant.
- Analyzed correlations between TLI, PLI, safety climate, safety behavior, risk perception, and accident experience.
- Compared TLI and PLI scores based on subjective accident experience.
Main Results:
- TLI and PLI demonstrated significant positive correlations with safety climate and safety behavior.
- TLI and PLI showed significant negative correlations with risk perception.
- Significant differences in TLI and PLI were found across varying levels of accident experience.
Conclusions:
- TLI and PLI are potentially valuable extensions to existing safety culture indicators in Korean industries.
- Findings suggest the utility of these prevention culture indicators across diverse cultural contexts.
- The study contributes to the global dissemination of a prevention culture through cross-cultural validation.

01:15Natural Selection and Adaptation
421
Natural selection, a fundamental concept in evolutionary biology, is the mechanism by which evolution is driven, favoring organisms that are best adapted to their environments. This process enhances their chances of survival and reproduction. Adaptation, a key outcome of this process, involves genetic modifications that optimize an organism's functionality under specific environmental challenges, such as extreme cold or thinner air at high altitudes.

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Individualist and collectivist cultures emphasize different core values, shaping personality in distinct ways. In individualist cultures, such as those in the United States, England, and Australia, people prioritize independence, competition, and personal achievement. These societies tend to promote self-focused traits, with individuals often reporting higher levels of self-esteem. In contrast, collectivist cultures, commonly found in regions like Asia, Africa, and South America, emphasize...

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
