Background: The rapid growth of computer technology in recent decades suggests that people today, in addition to print media, have many electronic information items that need to be managed appropriately and have increased the use of personal computers.Aims: This Researches descriptive and analytical based on the purpose of applied Research, and in terms of data collection and nature and comparison between the activities of personal information management and two measures of knowledge and skills has been presented.Methodology: The statistical population includes the students of Jundishapur University of Medical Sciences in Ahvaz in the academic year 2017-2018. To determine the statistical population, the sampling method was used by determining the total number of students 1300 and using the Karjesi-Morgan table, the approximate number of the sample was determined to be 297. The data collection was done using the questionnaire of 2012 and in order to analyze Pearson and Spearman correlation tests and AMOS and SPSS software were used.Results: The results of the survey show that knowledge and skill variables have a significant and positive effect on personal information management, and age, level of education, and school of study have a significant and positive effect on personal information management.Conclusions: The results of the research show that the status of personal information management of medical students in Jundishapur Ahvaz has a positive and meaningful effect based on the knowledge and skills of the students. According to the changes made in the management of personal information activities, it can be said that the difference in the amount and amount created in the variables of personal information management can be seen. The main reasons for this can include not having enough time, work pressures and lack of familiarity with the activities required for personal information management.

Background: Understanding color preference in virtual environments is crucial for applications in digital design, human-computer interaction, and virtual reality (VR).Aims: This study examines how luminance, hue, and saturation influence color preference in VR settings, considering both environmental and perceptual factors.Methodology: A controlled VR experiment was used, where participants interacted with two distinct virtual zones designed to simulate different lighting conditions.Finding: The findings suggest that chromatic lightness and perceived hue play distinct roles in color preference, with evidence supporting Weber's Law of illumination adaptation. It was also shown that regions with elevated chroma exhibit more pronounced colors. Additionally, the participants' average color preferences were determined, and the appropriate modification rate was extracted by comparing the preferred colors to the average colors of the virtual spaces. One significant finding was that, cooler colors were favored to warmer ones, which is consistent with previous research on color preferences. Furthermore, a correlation between lighting circumstances and color preferences was established.Conclusion: The findings indicated that adjusting the hue, saturation, and brightness can improve the design of virtual environments by matching the tastes of users. These insights contribute to a deeper understanding of color perception in digital spaces and have implications for design, architecture, and cognitive science.
