The Relationship between Time Management, Self-efficacy and Entrepreneurship among Students

Manpower is nowadays addressed as an infinite resource and the drive of any development. Meanwhile, entrepreneurs, in particular, play a significant role in the economic development process. The present study aims at investigating the relationship between time management, self-efficacy and entrepreneurship among Technical School students. The population under study is comprised of all the students majoring in the Female School of Technical Arts in Ramsar in the academic year 2011 – 2012. 150 of which were selected through cluster random sampling as the research sample. The participants responded to the Time Management, general Self-efficacy and Entrepreneurial questionnaires enjoying the validity of 86%, 6/80% and 90%, respectively. The obtained data were analyzed employing multivariate regression analysis and Pearson correlation coefficient. The findings indicated a positive significant relationship between time management, self-efficacy and entrepreneurship among students (p<0.01). Time management and self-efficacy could explain 8% of the variance occurred in entrepreneurship

The Impact of Silymarin on the Symptom Severity in Pediatric Patients with Inflammatory Bowel Disease: A Randomized Clinical Trial

Background: Inflammatory Bowel Disease (IBD) is a multifactorial disease, posing significant challenges to public health. The aim of this study is to determine the effect of silymarin on the symptom severity in pediatric patients with IBD.Methods & Materials: This randomized clinical trial was conducted on children aged 5-18 diagnosed with IBD referred to the GI clinic at Akbar Children's Hospital in Mashhad. Those who met the inclusion criteria were randomly allocated into either the intervention or placebo group, each group consisting of 20 participants. In the intervention group, silymarin was administered three times daily in divided doses for three months. The control group received a placebo. To assess the efficacy of silymarin, PUCAI and PCDAI were evaluated for all patients at three different time points: before the intervention, during the first visit, and after the intervention. Data were analyzed utilizing the SPSS version 25, with a significance level set at p 0.05). However, a statistically significant difference was observed in the disease activity index score between the two groups during the second, and third evaluations (p<0.05)

Experimental Demonstration of the Vibrational Stability Phenomenon in Bio-inspired Flight

Flapping wing micro-air-vehicles (FWMAV) are micro-air-vehicles that use biomimetic actuation (oscillatory flapping wing) for lift, propulsion, and control. The dynamic behavior of these bio-inspired systems is expressed by a multi-body, multi-time-scale, nonlinear, time-varying dynamical system model. This rich dynamic leads to unconventional stabilization mechanisms whose study essentially necessitates a mathematically rigorous analysis. Higher-order averaging, which is based on chronological calculus, can be utilized to show that insects and their man-made mimics (FWMAVs) exploit vibrational control to stabilize their body pitching angle. Such an unconventional stabilization cannot be proved by direct averaging. To experimentally demonstrate this phenomenon, an experimental setup was constructed. This setup allowed for two degrees of freedom for the body; vertical motion and pitching motion. It is found that there is a flapping frequency threshold beyond which the body pitching response is naturally (without feedback) stabilized, which conforms with the vibrational control concept. Moreover, a replica of the setup is fabricated with the FWMAV being replaced by a propeller revolving at a constant speed, which results in a constant aerodynamic force, leaving no room for vibrational control. The response of the propeller-setup is unstable at all frequencies, which also verifies the fact that the observed stabilization of the FWMAV-setup at high frequencies is due to vibrational stabilization

Deformation Risk Assessment of the Lar Dam: Monitoring Its Stability Condition

Dam stability is one of the most essential geotechnical engineering challenges. Studying the structural behavior of dams during their useful life is an essential component of their safety. Terrestrial surveying network approaches are typically expensive and time-consuming. Over the last decade, the interferometric synthetic aperture radar (InSAR) method has been widely used to monitor millimeter displacements in dam crests. This research investigates the structural monitoring of the Lar Dam in Iran, using InSAR and the terrestrial surveying network technique to identify the possible failure risk of the dam. Sentinel-1A images taken from 5 February 2015 to 30 September 2019 and TerraSAR-X (09.05.2018 to 16.08.2018) images were analyzed to investigate the dam’s behavior. The InSAR results were compared with those of the terrestrial surveying network for the period of 1992 to 2019. The Sentinel-1 results implied that the dam on the left side moved over 8 mm/yr. However, the pillars to the left abutment indicated an uplift, which is consistent with the TerraSAR-X results. Also, the TerraSAR-X data indicated an 8 mm displacement over a three-month period. The terrestrial surveying showed that the largest uplift was 19.68 mm at the TB4 point on the left side and upstream of the body, while this amount was 10 mm in the interferometry analysis for the period of 2015–2020. The subsidence rate increased from the middle part toward the left abutment. The geological observations made during the ninth stage of the terrestrial surveying network indicate that there was horizontal and vertical movement over time, from 1992 to 2019. However, the results of the InSAR processing in the crown were similar to those of the terrestrial surveying network. Although different comparisons were used for the measurements, the difference in the displacement rates was reasonable, but all three methods showed the same trend in terms of uplift and displacement

Management of Infantile Colic; Based on Traditional Iranian Medicine

Introduction Infantile colic is a common disorder in the three first months of childhood. There is no clear management in treating this disease which may lead to psychosocial consequences in parents. Due to the importance of infantile colic in Traditional Iranian Medicine (TIM) in this study was conducted. Materials and Methods In this review article, we searched the words for colic infantile like "Maghs e Atfal" in the clinical textbooks of TIM and electronic databases were searched for "Infantile Colic", "Herbal Medicine", "Traditional Medicine" and "Complementary Medicine" keywords to obtain any relevant study. Results In TIM, infantile colic is called "Maghs e Atfal". TIM scholars believed that it can be caused by bloating in stomach, eating a lot of food or milk and subsequently mal-digestion. The treatment is based on the probable etiology. In bloating in stomach, the first step is to modify breast milk by the mother’s eating anti-flatulence drugs and avoiding any flatulent food. Foeniculum vulgare and Trachyspermum ammi are recommended to be consumed with milk by the child. Conclusion According to the benign nature of the colic, complementary medicine can be a priority in treatment. In this viewpoint, the mother's diet modification, and consequently of her milk, are very important. Avoiding any flatulent food and consumption of anti-flatulence plants are based on its treatment

Right Ventricular Myocardial Tissue Velocities, Myocardial Performance Index, and Tricuspid Annular Plane Systolic Excursion in Totally Corrected Tetralogy of Fallot Patients

Background: Longer survival after the total repair of the Tetralogy of Fallot increases the importance of late complications such as right ventricular dysfunction. This is a prospective study of the right ventricular function in totally corrected Tetralogy of Fallot patients versus healthy children. Methods: Thirty-two healthy children were prospectively compared with 30 totally corrected Tetralogy of Fallot patients. Right ventricular myocardial tissue velocities, right ventricular myocardial performance index, and tricuspid annular plane systolic excursion were investigated as well as the presence and severity of pulmonary regurgitation. Results: The two groups were age-and sex-matched. Mean systolic peak velocity (Sa) and tricuspid annular plane systolic excursion were significantly decreased, while myocardial performance index and early to late diastolic velocity (Ea/Aa) were significantly increased in the Tetralogy of Fallot patients. Early diastolic velocity (Ea) showed no significant difference between the two groups. Sa correlated significantly with tricuspid annular plane systolic excursion in both the normal children and totally corrected Tetralogy of Fallot patients. Myocardial performance index was significantly higher in the patients with moderate to severe pulmonary regurgitation than in those with mild regurgitation. However, there was no significant correlation between this index and right ventricular myocardial tissue velocities. Conclusion: In this study, systolic right ventricular function indices (Sa and tricuspid annular plane systolic excursion) were impaired in the totally corrected Tetralogy of Fallot patients. Myocardial performance index was affected by the severity of pulmonary regurgitation

Synbiotic in the management of infantile colic: A randomised controlled trial

Aim Infant colic is a frequent problem affecting up to 10-30% of infants in first 3 months of life. Results from previous trials have shown that manipulation of gut microbiota can lead to symptomatic improvements. In a randomised clinical trial, we aimed to determine efficacy of synbiotic in reducing average infant crying time at day 7 and day 30 after starting intervention. Methods Fifty breastfed infants aged 15-120 days with infantile colic randomly assigned to receive either the synbiotic sachet containing 1 billion CFU of: Lactobacillus casei, L. rhamnosus, Streptococcus thermophilus, Bifidobacterium breve, L. acidophilus, B. infantis, L. bulgaricus and fructooligosacharide (Protexin Healthcare, Somerset, UK), or placebo daily for 30 days. Parents were asked to record details of crying times in a symptoms diary. The primary outcome measure was the treatment success (reduction in the daily crying time >50%) and the secondary outcome measure was symptom resolution (reduction in the daily crying time >90%). Results The treatment success was significantly higher in synbiotic group (82.6%) compared with placebo (35.7%) at day 7 (P < 0.005). At day30, treatment success was 87% and 46% in synbiotic and placebo group, respectively (P < 0.01). Symptom resolution was also higher in synbiotic group (39%) compared with placebo (7%) at day 7 (P < 0.03) but not at day 30 (56% vs.36%, P = 0.24). We encountered no complication related to synbiotic use. Conclusion This synbiotic (a mixture of seven probiotic strains plus FOS) significantly improved colic symptoms in comparison with placebo
