Cryptanalysis of Reduced round SKINNY Block Cipher
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different versions of SKINNY .We utilize Mixed Integer Linear Programming (MILP) to search all zero-correlation linear distinguishers for all variants of SKINNY, where the longest distinguisher found reaches 10 rounds. Using a 9-round characteristic, we present 14 and 18-round zero correlation attacks on SKINNY-64-64 and SKINNY- 64-128, respectively. Also, for SKINNY-n-n and SKINNY-n-2n, we construct 13 and 15-round related-tweakey impossible differential characteristics, respectively. Utilizing these characteristics, we propose 23-round related-tweakey impossible differential cryptanalysis by applying the key recovery attack for SKINNY-n-2n and 19-round attack for SKINNY-n-n. To the best of our knowledge, the presented zero-correlation characteristics in this paper are the first attempt to investigate the security of SKINNY against this attack and the results on the related-tweakey impossible differential attack are the best reported ones

General health and its association with sleep quality in two groups of nurses with and without shift working in educational centers of Iran University of Medical Sciences (IUMS
Background and aim: The health condition of nurses as caregivers influences the quality of care received by patients. To reach the maximum performance, nurses themselves need be health. Nurses, because of the nature of their career confront many types of stresses in their work environment and they are among people that are prone sleep disorder because of working in morning, evening, night and especially, rotation shifts. The aim of this study is comparison of the general health and sleep quality of nurses in two groups of without shift and with shift working in IUMS- 2006. Methods: It was a descriptive - analytical study. The setting was hospitals affiliated to IUMS. Five hundreds and twenty nurses were recruited using stratified random sampling. To survey the general health and sleep quality of nurses General Health Questionnaire - 28 and Pitsberg Sleep Quality Index tools were used. Results: Chi – Square test indicatod that there was a significant difference between general health of without shift and with shift workers, so that general health of without shift workers was better than rotation shift ones. The sleep quality of without shift nurses was also better than rotation shift ones (r=0.692, P<0.001). There was a direct correlation between general health state and sleep quality (P<0.001). Conclusion: Based of the finding of this study, appropriate and efficient managmant and careful planning of working shifts is suggest to reduce sleep disturbances in nurses. Promotion of nurse’s quality of sleep can promote their general health and eventually promotes the quality care of patients
The comparison of neuropsychological performance in the girl students with social anxiety disorder and normal students
Background and aims: The Neuropsychological performance in patients with anxiety disorders has received much less attention. The present study set out to compare one of the executive performances that means shifting function in two groups of social anxious and normal. Also, The aim of the present study was to investigate performance in this function both of processing efficacy and performance effectiveness.
Methods: In this causal-comparative study, recruited 24 patients with social anxiety disorder and 24 non patients in multi-stage cluster sampling method and were implemented tests of Connor Social Anxiety Scale, Self-reported mental effort scale, and Wisconsin Card Sorting Test, The results were analyzed with SPSS software and MANOVA test.
Results: The results showed significant differences between the two groups in both components of performance in the shifting function namely processing efficacy (P<0.001) and performance effectiveness (P<0.001), So that socially anxious group showed poorer performance.
Conclusion: The group of social anxious in compare with normal group showed deficient in the shifting function of working memory. The deficiency observed were related to cognitive models of anxiety disorders specially Attentional Control Theory
Effect of Mothers' Educational Supportive Care Program on Pain Intensity and Crying Duration Caused by Colic Pain in Infants Aged 1-5 Months
Background: Baby colic is one of the most common digestive problems in infants. Due to its several and unknown causes, colic treatment depends on the parent's individual and social education and support. Aim: This study aimed to determine the effect of mothers' educational supportive care program on the pain intensity and crying caused by colic in infants aged 1-5 months. Method: This study was conducted based on a randomized controlled clinical trial. This study included 88 infants with colic who were referred to a specialized pediatric clinic at a public hospital in eastern Iran. The patients were randomly divided into the intervention and control groups. The educational supportive care program was implemented for eight days and the infant crying duration and frequency were recorded each day.

Evaluation of the Photosonolysis Process Efficacy for the Removal of Anionic Surfactant Linear Alkyl Benzene Sulfonate from Aqueous Solutions
In this study, the experiments on the sulfonate linear alkylbenzene (LAS) solution were performed using the methylene blue active substances (MBAS) method. The effectiveness of the sonochemical and photochemical reactors for LAS degradation was evaluated with an emphasis on the effect of the contact time, pH values, type of process and initial concentrations. The experiments were carried out at the initial concentrations of 0.5 mg/L, 14.00 mg/L and 21.00 mg/L, the contact time of 8, 16, and 24 minutes, pH of 3, 7, and 11, the ultrasonic frequency of 42 kHz, the acoustic power value of 160 W, an ultraviolet lamp with 150W power and the wavelength of 254 nm. This study showed that the LAS degradation was increased along with the contact time. In addition, at alkaline pH, the removal efficiency increased as well. Overall, the results obtained from this research demonstrated that by themselves, both the sonochemical and photochemical reactors may not be useful for completely reducing the complex wastewaters with high surfactant loads, but the succession of the UV/US process has a significant effect on the removal of anionic detergents. These findings demonstrated the removal efficiency under alkaline conditions and the contact time of 24 minutes was equal to 96.97 percent
The Relationships between Mental Health Status, Achievement Motivation, Job Satisfaction and Oxidative Stress in Subjects Exposed to Nickel Welding Fumes
This study was conducted on 27 male welding workers who worked in a company that manufactures road construction machinery and is located in an industrial part of Iran, in the Central province. In the serum, total antioxidant capacity (TAC), lipid peroxidation (LPO), DNA damage (8-OH-dG)was measured. Mental health status was evaluated by General Health Questionnaire (GHQ-28) and achievement motivation was evaluated by Herman’s achievement motivation Test (ACMT), and job satisfaction was measured by Dennett Job Satisfaction Test. The results of this study showed that there was a reverse significant relationship between nickel and TAC with ACMT and job satisfaction. The oxidative stress of Ni ended up in psychological disorders. As oxidative stress causes psychological disorders, the welding workers suffered from more psycho- pathology and were in need of greater care
Effects of Yakson Therapeutic Touch and Heel Warming on Pain Caused by Heel Stick Procedure, Vital Signs, and Cry Duration in Full-term Neonates
Background: Neonates are more sensitive to pain and likely to suffer from its long-term complications. Therefore, various methods including non-nutritive sucking, sensory stimulations, and various supportive interventions are employed to relieve pain in newborns. Aim: This study aimed to compare the effects of Yakson therapeutic touch and heel warming on pain caused by heel stick procedure, vital signs, and cry duration in full-term neonates. Method: This randomized clinical trial was conducted among 78 full-term newborns referred to healthcare centers in Mashhad, Iran, 2017. They were assigned into three groups of Yakson theraputic touch, heel warming using a hot-water bottle with the temperature of 40°C, and control receiving routine care, through randomized block method. Then, vital signs before and after and pain intensity after heel-stick procedure were measured using Neonatal Infant Pain Scale (NIPS). Data analysis was performed using Kruskal-Wallis and Wilcoxon tests in SPSS software, version 16. Results: The study groups were homogeneous considering demographic characteristics. The results of Kruskal-Wallis test showed a significant difference between the groups regarding the mean scores of the NIPS at the post-intervention phase (P=0.02). However, no significant difference was observed between pre- and post-intervention phases in the groups considering respiratory and heart rates. Additionally, cry duration significantly reduced in the group that received Yakson therapeutic touch (P=0.03). Implications for Practice: The use of Yakson therapeutic touch could relieve pain, soothe the neonates, and shorten cry duration in newborns after heel stick procedure. Nevertheless, heel warming only increased up blood flow for easier blood sampling
