BACKGROUND To increase knowledge and competence about first aid in the population, first-aid instruction is included in primary and secondary school curricula. This study aimed to establish how much time is spent on first-aid training, which first-aid measures are taught, and which factors prevent teachers from providing the quantity and quality of first-aid training that they wish to give.

Article history: Received 18 November 2010 Available online 17 February 2011 Interest regarding the challenge-hindrance occupational stress model has increased in recent years, however its theoretical foundation has not been tested. Drawing from the transactional theory of stress, this study tests the assumptions made in past research (1) that workload and responsibility are appraised as challe...

The chapter describes the modeling of a material handling system with the production of individual units in a scheduled order. The units represent the agents in the model and are transported in the system which is abstracted as a directed graph. Since the hindrances of units on their path to the destination can lead to inefficiencies in the production, the blockages of units are to be reduced. ...

For a surgeon, an operating room is no less than place of worship, where he/she buds into surgical craftsperson. any subspecialty theater cornerstone on which its foundation laid.[1] One cannot imagine the subspecialties without procedures being performed.

We described a novel tumor-associated immunosuppressive mechanism based on post-translational modifications of chemokines by reactive nitrogen species (RNS). To overcome tumor immunosuppressive hindrances, we designed and developed a new drug, AT38, that inhibits RNS generation at the tumor site. Combinatorial approaches with AT38 boost the effectiveness of cancer immunotherapy protocols.

We will illustrate the dichotomy between original data and published data in the context of usability for Meta-Analysis. We will show how to use SAS® for these two cases and suggest possible solutions to overcoming the hindrances caused by the use of published data. Publication bias, Bayesian methods for Meta-Analysis, and other related topics will be discussed.
