To control coal miner’s unsafe behavior, miner and manager behaviors were analyzed, and a behavior control system model was constructed. The necessity conditions of optimal management behavior of coalmine manager in both complete information and incomplete information condition were studied. The result established that, only if the estimated value of unsafe behavior by manager was the same as t...

UNLABELLED With changing conditions affecting receipt of postabortion care, an updated estimate of the incidence of treatment for complications from unsafe pregnancy termination is needed to inform policies and programmes. National estimates of facility-based treatment for complications in 26 countries form the basis for estimating treatment rates in the developing world. An estimated seven mil...

A class of software is identified where a nondeterminism analysis is not inherently less safe than a deterministic analysis. Tools built for that class of software can be simple to build, fast to run, and scale to very large problems. An examples of one such tool is discussed here.

background: this study aimed to evaluate the workers safety behavior and to determine the importance of each unsafe behavior in an iranian steel manufacturing company. methods: this study was conducted in mobareke steel manufacturing company, which is located in the middle of iran, in 2007. the methodology was based on the safety behavior sampling (sbs) technique and entropy. after specifying t...

Ernest Sosa has argued that if someone knows that p, then his belief that p is “safe,” and Timothy Williamson has agreed. In this paper I argue that safety, as defined by Sosa, is not a necessary condition on knowledge—that we can have unsafe knowledge. In the next section I present Sosa’s definition of safety, and in section III I present a counterexample to it as a necessary condition on know...

Many of the activities in construction tend to lead to accident occurrences. The major causation of the accidents in this industry is fall from height. In developing countries such as Thailand, there are too many unsafe conditions in construction activities performed at high elevation. Although, the government enforces safety rules and regulations, safety facilities are still provided inadequat...
