CONFISCA: An SIMD-Based Concurrent FI and SCA Countermeasure with Switchable Performance and Security Modes

CONFISCA is the first generic SIMD-based software countermeasure that can concurrently resist against Side-Channel Attack (SCA) and Fault Injection (FI). Its promising strength is presented in a PRESENT cipher case study and compared to software-based Dual-rail with Pre-charge Logic concurrent countermeasure. It has lower overhead, wider usability, and higher protection. Its protection has been compared using Correlation Power Analysis, Welch’s T-Test, Signal-to-Noise Ratio and Normalized Inter-Class Variance testing methods. CONFISCA can on-the-fly switch between its two modes of operation: The High-Performance and High-Security by having only one instance of the cipher. This gives us the flexibility to trade performance/energy with security, based on the actual critical needs.

Examining the Effective Factors on Villagers’ Tendency to Retrofit Rural Housing in Iran

This research is an applied one with a descriptive – analytic method was conducted in Jahrom with the objective of analyzing the effective factors on retrofitting of rural homes. Our statistical universe includes 11 villages of Simekan district in the suburbs of Jahrom County, these villages have taken a loan over 50 items from Housing Foundation. For estimating the sample volume at rural family level, by using Cochran sampling method with 95 percent accuracy, the number of 186 persons (family guardian) was questioned by simple random sampling method. Then, the necessary information was gathered by survey and questionnaire. Based on the results of factor analysis, among the first two factors in the order of effectiveness proportion, the first factor (satisfaction with rural homing) describes 57.455 percent of variance by itself and the second factor (homing retrofitting) is accounted for 20.835 percent of variance. Also, it was found that the best reason for retrofitting of rural homes is using of rural homing facilities (67%). Safety against natural disasters such as earth quake and flood (33%) is another reason for homing retrofitting, so our main hypothesis is supported. According to the results of hypothesis testing, based on Pearson correlation coefficient and regarding to variance testing and our significance number which is more than 0.05, there isn’t a significant difference between our independent variables (gender, age & education) and housing retrofitting.

Thus, auditory, intellectualy, repetition learning model using audio visual media have an effect on science knowledge competence of fourth grader students of SD Gugus Kompyang Sujana in North Denpasar in academic year 2017/2018.

Genotoxic and cytotoxic effects of Haas appliance in exfoliated buccal mucosa cells during orthodontic treatment

ABSTRACT Objectives: To evaluate the genotoxic and cytotoxic effects of Haas appliances through micronuclei test and cytogenetic damage analysis in buccal mucosa epithelial cells of patients undergoing orthodontic treatment. Materials and Methods: Twenty-eight patients, 6–12 years of age and of both genders, who required a Haas appliance for the correction of a posterior crossbite were included. Epithelial cells from the mucosa were collected by gently scraping the inside of both the right and left cheeks. The cells were collected before the insertion of the appliance (T0), 1 month after the device was installed (T1), and again 3 months after the appliance was immobilized (T2). The cells were processed to obtain slides. Feulgen/Fast Green was used as the staining method, and the number of normal, karyolytic, pyknotic, nuclear buds, bi/trinucleated, and micronucleus cells were counted under light microscopy. Cellular abnormalities were evaluated with parametric and nonparametric tests for comparison of the means by analysis of variance testing, Tukey posttest, or the Kruskal-Wallis test and then by Dunn's posttest. The significance level was 5%. Results: There were no statistically significant changes in the micronuclei in the evaluated periods (P > .05). Nuclear buds increased at T1 (P < .05), returning to baseline levels at T2. Other abnormalities (cariolytic, pyknotic, and bi/trinucleated cells) showed a significant increase at T1 and T2 (P < .0001). Conclusions: The Haas appliance did not cause an increase in micronuclei in cells of the buccal mucosa. However, statistically significant increases in cariolytic, pyknotic, and bi/trinucleated cells were observed during treatment, suggesting possible DNA damage.

PEMODELAN SISTEM AKUNTANSI MANAJEMEN BERKOMPUTER UNTUK MENINGKATKAN MOTIVASI DAN KINERJA UMKM MANUFAKTUR

The usefulness of management accounting system (MAS) would be enjoyed if SME owners take the initiative to use MAS. This research suggests that the perived of easy, perceived of usefulness, and user attitudes will affect owners/management’s behavior intention to use a computerized-based MAS. If the behavior intention to use is high, then the intrinsic motivation of users is expected increase also. Increasing intrinsic motivation of SME owners are expected to improve their performance. The sample was manufacturing SMEs in Surabaya and surrounding areas. The result of regression analysis conclude about MAS that: (a) Intrinsic motivation shows significantly positive effect on the SMEs performance, both managerial or financial performance, (b) behavior intention to use MAS do not significantly influence the motivation, (c) the usefulness and ease of use do not significantly influence the behavior intention to use MAS, and (d) users’ attitude significantly influence the behavior intention to use MAS. Further analysis of variance testing found evidence of: (1) there is a difference in perception between the groups using the manual MAS and the group using computerized-based MAS. This finding affirms the benefits of computerized-based MAS through higher means on all of variables; and (2) if the users perceive that the use of computerized-based MAS is much easier, then the performance will be significantly different.

Level of Visual Acuity Necessary to Avoid False-Positives on the HRR and Ishihara Color Vision Tests

Purpose Minimizing false-positives (FPs) when evaluating color vision is important in eye care. Identification of plate 1 (demonstration plate) is often considered a way to avoid FPs. However, few studies have quantified the minimum level of visual acuity (VA) that would minimize FPs for the Ishihara and HRR color tests. Methods Threshold levels of optical defocus were obtained from 25 color normal subjects. Blur levels were obtained for Ishihara (38 plate) plates 1, 10, and 15 and 4th edition HRR plates 1, 7, 10, and 20 using the method of limits. Corresponding VAs were measured through these blur levels at 40 centimeters after adjusting for the dioptric distance difference. Analysis of variance testing was used to analyze the data. Results Mean optical defocus values in diopters (mean ± SD) for HRR plates 1, 7, 10, and 20 were 6.23 ± 1.61, 1.23 ± 1.16, 2.41 ± 1.31, and 7.96 ± 2.03, respectively, and for Ishihara plates 1, 10, and 15 were 5.70 ± 1.52, 3.68 ± 1.71, and 4.62 ± 1.56, respectively. There was a significant difference between the screening and demonstration plates for both tests (p<0.001). Conclusions Based on the plate in each test that was found to be the least tolerant to blur, the average minimum VAs needed to identify the screening plates were approximately 20/180 for the Ishihara test and 20/50 for the HRR test. Identifying the demonstration plate in the Ishihara and HRR tests does not ensure FPs will be avoided.
