In the psychological context of the environment, color is discussed as another environmental factor that has a great impact on human perception and behavior. In the study of psychological-mental performance of individuals, indicators are used that indicate the individualchr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))s cognitive status. Therefore, the aim of this systematic review study is to investigate the effect of color on Psychological functions of individuals.

This article is a systematic review study. Published full-text and English articles were searched in PubMed, Scopus, Science Direct ISI Web of Knowledge databases with the keywords color, function, cognitive, psychological without time limit and 60 eligible articles were reviewed.

Initially, 312 articles were identified from various databases. Among them, 123 articles had inclusion criteria. After that, 63 articles were excluded from the study due to lack of experimental studies and 60 articles were selected for final review. A total of 6 studies on selective attention,3 studies on alertness,4 studies on sport performance,7 studies on intellectual performance,7 studies on aggressiveness/dominance Evaluation,7 studies on caution/avoidance,6 studies on attraction,5 studies focused on store/company evaluation,7 studies focused on eating/drinking,4 Studies on memory,2 Studies on arousal and 2 Studies on time perception. The results show that color has a significant effect on cognitive functions including selective attention, alertness, Sport performance, intellectual performance, aggressiveness/dominance Evaluation, caution/avoidance, attraction, store/company evaluation, eating/drinking, time perception, memory and arousal.

Color should be considered as one of the main ways to promote mental health, perception and behavior of people.

Due to high potential consequences of pipeline accidents, it is necessary to manage the inherited risks in the pipeline sectors. Several techniques are available to identify hazardous situations; however, it is crucial that the selected tool be fitted for the proposed scope. HAZOP study is one of the most accepted techniques by experts to identify hazards. Despite of the wide application of HAZOP in the process industries, this method is not suitable for pipelines. In this study, a new extension of HAZOP (P-HAZOP) is introduced through integrating the classic HAZOP and the Kent’s method. This research focuses on producing the new sort of deviation for pipelines. A previously conducted HAZOP study for a network of pipelines was repeated by using P-HAZOP. A large number of new generated deviations demonstrate more coverage of the P-HAZOP for pipeline scope. Finally, it is recommended to improve the traditional HAZOP for pipeline applications.
