This study investigated the effects of multiple cognitive tasks on human performance. Twenty-four students at North Carolina A&T State University participated in the study. The primary task was auditory signal change perception and the secondary task was a computational task. Results showed that participants' performance in a single task was statistically significantly different from their performance in combined tasks: (a) algebra problems (algebra problem primary and auditory perception secondary); (b) auditory perception tasks (auditory perception primary and algebra problems secondary); and (c) mean false-alarm score in auditory perception (auditory detection primary and algebra problems secondary). Using signal detection theory (SDT), participants' performance measured in terms of sensitivity was calculated as −0.54 for combined tasks (algebra problems the primary task) and −0.53 auditory perceptions the primary task. During auditory perception tasks alone, SDT was found to be 2.51. Performance was 83% in a single task compared to 17% when combined tasks.

The purpose of this study was to investigate the relationship between organizational and personal (individual) factors with the prevalence of musculoskeletal disorders (MSDs) in office workers of the Iranian Gas Transmission Company. The participants rated two questionnaires – the standardized Nordic Musculoskeletal Questionnaire to measure the prevalence of MSDs, and the Veterans Healthcare Administration All Employee Survey questionnaire (2004 version) – to measure psychosocial, organizational and individual aspects of job satisfaction and workplace climate. The highest prevalence of MSDs was found in the lower back (49.7%) and neck (49.0%) regions. Results of the logistic regression models showed that some psychosocial and organizational factors and also some individual factors were associated with prevalence of MSDs (p < 0.05).These ﬁndings illustrate the need to consider all elements of the work system as a whole in future studies and in organizational planning.

Istnieje wiele analogii pomiędzy kompozycją muzyczną i architektoniczną. Narzędzia analityczne teorii muzyki mogą posłużyć do odczytywania logiki dzieła architektonicznego. Muzyka nie musi podlegać rygorom funkcjonalności. Architektura przeciwnie, choć przecież względy użytkowe nie stanowią jej istoty. Muzyka przybliża nam naturę motywu i melodii, które są odpowiedzialne za geniusz utworu. Znalezienie podobnych elementów w architekturze może nam pomóc zrozumieć niepowtarzalność wybitnych budynków.

Analogy can be found in music and architectural composition. Tools that have been created by music theory can be useful in analyzing logical construction of a building. Music is free from the rigorous functionality. Architecture is the opposite, though must there be something more to it than just its utility. Music reveals the nature of a motif and melody, which seem to stand for the brilliance of an opus. To find similarities in architecture is to understand how a building becomes one of the kind.
