Published: September 2021

Cloud computing is the emerging technology where resources are available pay as you go basis. Cloud storage technology provides the large pool of storage capacity to the cloud users. Providing security to the data stored in cloud is the major concern. So, Security can be enhanced by providing access control to the authorized users. Access control gives the authorization to the users which gives the access privileges on data and other resources. Access control can be enabled in most of the computing environment such as Peer to Peer, Grid and Cloud.Access control is an important measure for the protection of information and system resources to prevent illegitimate users from getting access to protected objects and legitimate users from attempting to access the objects in ways that exceed what they are allowed. The restriction placed on access from a subject to an object is determined by the access policy. With the rapid development of cloud computing, cloud security has increasingly become a common concern and should be dealt with seriously. In this paper, an enhanced access control mechanism is proposed with hierarchical attribute-based access control method.

This paper reports a longitudinal study to know how the students what are the characteristics that students identify in themselves and in their peers associated with leadership. A questionnaire was applied to 286 students to find out the opinions of the students in relation to seven attributes of the behavior of their peers: 1) Is it accepted by the group? 2) Is it participatory? 3) Is it responsible? 4) Is it reliable? 5) Is it respectful? 6) Is it compromised? and 7) Is it punctual? In the results, differences were found that, although they are not significant, it is identified that those that most associate a leader are: That he be accepted by the group, that he be committed to its interests, and that he be respectful of the members of the community. It is concluded that the characteristics identified by the majority of the students in a leader are those directly related to the social acceptance in order of the resolution of possible conflicts will imply, and with those that guarantee, as far as possible, the achievement of common objectives and the achievement of goals set collectively.
The interpreter advantage in executive functions—A systematic review and meta-analysis
Authors: Hu Minxia , Fan Wenjiao 
Published: September 2021

Given the heavy cognitive load inherent in language interpreting, interpreters may develop cognitive advantages from managing frequent switching of linguistic codes and working modes. Based on a systematic review of executive functions of inhibiting, shifting and working memory (WM) updating by Nour et al. (2020) and meta-analysis of working memory by Wen and Dong (2019) and Mellinger and Hanson (2019), this research follows the PICOS framework and the PRISMA guideline to synthesize findings from 98 tasks of 29 original studies from International and Chinese databases with a cut-off date of 1st October, 2020. Substantial evidence for an interpreter advantage in shifting was found, but not for inhibition or updating. The meta-analysis showed 1) a moderate to high effect in shifting (g = 0.68, seven WCST effects; g = -0.32, eight switching cost effects); 2) no effect in inhibiting (g = 0.13, six Stroop effects); 3) mixed effects in WM updating. Subgroup analysis on WM updating revealed significant training effects from within-group comparisons (g = 0.58, five 2-back effects; g = 0.71, two L2 listening span effects), but insignificant difference from between-group comparisons (g = -0.03 , five 2-back effects; g = 0.18, five L2 listening span effects ). More reproducible behavioral research with scientific and consistent designs is needed for a clearer understanding of the relationship between interpreting experience and EFs.

Published: September 2021

According to the 2018 Global Nutrition Report, the habit of school-aged children choosing meals is still bad over the world. Around 30.3 % of school-aged children do not eat fruit daily, whereas 43.7 % consume soda daily. This study aims to increase student's knowledge about the material sources of nutrients in food through a game of grouping foodstuffs using a food model with a constructivist learning approach designed by the author. The participants in this study were 33 SDIT Raudhatul Jannah Lubuklinggau grade 4,5 and 6 students. The method used in this study uses an experimental design with a pre and post-test approach without control. Total sampling was used for sampling, and the Wilcoxon test was used for interpretation. This study was completed in March of 2021. Research results show a p-value of .000 (<.05), indicating that students' awareness of the material sources of nutrients in food increased after they were given a game grouping food ingredients using a food model. It is recommended that educators be able to provide students with learning resources that take a constructivist approach, such as games that actively engage students, so that students' awareness can be developed through direct experiences.

Authors: Syukri Daimon , . Rini , . Wellyalina , Yanti Nika Rahma , . Jaswandi 
Published: September 2021

Background: The difference in degradation time on the formation of carotene’s derivative aromatic compounds [β-ionone and dihydroactinidiolide (dhA)] due to thermal degradation process of carotenes in crude carotenoid extract of carrot was studied. Methods: β-ionone and dhA formation and that of carotenes degradation during thermal degradation (T=140°C) was observed periodically for 4 h. The constant oxygen supply during degradation was maintained at approx. 7 L/h. Result: The formation of β-ionone and dhA accumulated significantly with increasing duration of the degradation process. The maximum formation of β-ionone and dhA could be estimated with the pattern of carotenes degradation. After 4 h of degradation, more than 80% carotene has degraded. It can be concluded that the degradation process of crude carotene extract from carrots at temperature of 140°C will result in a maximum carotene degradation process when the degradation process is carried out for 5 h.

Authors: Ayyoub Abed Alkarim , Jabali Oqab 
Published: September 2021

Educational institutions strive to achieve their purposes mainly assessing students’ performance and abilities; they might use traditional types of assessment or they may be forced to apply electronic assessment in certain situations such as those dictated by the current spread of COVID-19 Pandemic. The current study aims at providing insights into the ways and levels of university students' evaluation of the electronic assessment during the global health crisis whether this evaluation is affected by certain demographic variables or not. A 29-item online questionnaire was developed and conducted by the researchers to survey a large sample of university population. A large number of the students (n=582) responded to the survey. The study results show that the level of students’ evaluation of e-assessment is moderate. The researchers also find that an interaction between gender and faculty may influence students’ evaluation positively and negatively. The implications of the study suggest that educational institutions should consider all types of assessment mainly e-assessment to keep pace with all advancements and evade unexpected circumstances like pandemics.
