Breast cancer is the first or second malignancy among women worldwide. Illness perception (IP) and quality of life (QoL) are major issues considering breast cancer management. An attempt was here made to inspect the predictive variables influencing IP and their impact on QoL in cancer patients. The key predictors adapted from previous studies including life satisfaction, perceived social support, self-esteem, hope, optimism, and spiritual well being were taken into account. Our sample included 200 female volunteers suffering from breast cancer applying exclusion criteria. The data were collected using various questionnaires and statistically analyzed by means of path analysis and structural equation modeling. The results revealed that of the six predictors, spiritual well being and social support had direct effects on QoL and IP. The only path with significant indirect correlation with IP was social support. Spiritual well being had the second significant direct effect on IP. Self-esteem occupied the third rank in direct effects on both QoL and IP. In conclusion, here in Iran and most likely in other strongly religious communities, spiritual intervention is an effective strategy to raise QoL. Also social support helps women suffering from breast cancer to experience better conception and coping strategies.

Under mild conditions and without any additional organic solvent, synthesis of carbamatoalkyl naphthols could be carried out in the present of two halogen-free Br${\phi}$nsted acidic ionic liquids, 3-methyl-1-(4-sulfonic acid)butylimidazolium hydrogen sulfate and N-(4-sulfonic acid)butylpyridinium hydrogen sulfate. A wide range of aromatic aldehydes easily undergo condensation with $\beta$-naphthol and methyl or benzyl carbamate to afford the desired products of good purity in excellent yields. The present methodology offers several advantages such as a simple procedure with an easy work-up, short reaction times, and excellent yields. The catalysts could be recycled and reused for several times without substantial reduction in their catalytic activities.

In the conventional method of designing structures, a number of constants often characterize decisive parameters such asdimensions, material strengths and loads. Insufficient precision in modeling and implementing the structures are among theuncertainties that exist in structural design. If the maximum safety is expected for a structure, a combination of optimization andreliability should be used; this means that the structure should be optimized on the basis of reliability rather than economicconsiderations. In this study, geometry optimization of different steel frames has been done based on reliability; in fact, the objectiveis to obtain dimensions which are expected to have the best performance in terms of safety. To do so, different failure surfaces shouldfirstly be defined and the structure should be optimized on the basis of the maximum reliability possible. The answer to the problemis the maximum distance from the defined failure surface obtained by probabilistic method. Also, decision-making analysis, which isthe principle of engineering judgment, has been defined in the mathematical model so that the structural engineer has more options todetermine the type of structural performance. The solution of linear and non-linear problems can be determined by implementing thealgorithm for several times. Genetic algorithm can obtain the design point and probability of failure in statistical problems; therefore,it has been used to find the best dimensions of the frame under study.

Damage identification of a 2D frame structure using two-stage approach

Seyed Rohollah Hoseini Vaez,Narges Fallah 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.3

In this article, a two-stage damage identification approach is employed to detect the site and extent of multiple damage cases in a 2D frame structure. In the first stage, Damage locating vector (DLV) method based on a new indicator called EDS (Exponential decreased stress) is applied to localize the damaged elements. Next, the damage extents of suspected elements are quantified using two metaheuristic algorithms, Water evaporation optimization (WEO) and accelerated WEO. Numerical example consists of a 2D frame structure with two types of meshing elements, 35 and 105 frame elements. For every state, two multiple damage cases are tested in noisy condition. To compare performance of the two-stage method with one-stage optimization method, the studied cases are also run using these two metaheuristic algorithms. The results indicate that the two-stage approach is more effective than one-stage because the number of intact element detected as damaged one and computational errors for actual damaged elements in one-stage method are more while the two-stage approach spends a much shorter time.

M. M. Hoseini-Athar,B. Tolaminejad 대한금속·재료학회 2016 METALS AND MATERIALS International Vol.22 No.4

Explosive welding is a well-known solid state method for joining similar and dissimilar materials. In the present study, tri-layered Al-Cu-Al laminated composites with different interface morphologies were fabricated by explosive welding and subsequent rolling. Effects of explosive ratio and rolling thickness reduction on the morphology of interface and mechanical properties were evaluated through optical/scanning electron microscopy, micro-hardness, tensile and tensile-shear tests. Results showed that by increasing the thickness reduction, bonding strength of specimens including straight and wavy interfaces increases. However, bonding strength of the specimens with melted layer interface decreases up to a threshold thickness reduction, then rapidly increases by raising the reduction. Hardness Values of welded specimens were higher than those of original material especially near the interface and a more uniform hardness profile was obtained after rolling process.

Seyed Mohamad Hoseini,Hossein Parastesh,Iman Hajirasouliha,Ahmad Ferdowsi 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.6

This study aims to introduce a novel optimal structural design framework for buckling-restrained braces (BRBs) in multi-story buildings. Five artifi cial intelligence (AI) algorithms, including particle swarm optimization (PSO), shuffl ed frog-leaping algorithm (SFLA), interior search algorithm (ISA), hybrid of bat and particle swarm optimization (BAT-PSO), and political optimizer, which is recently proposed, are adopted for the optimum design of BRB systems. In the proposed optimization process, the BRB cross-sectional area is taken as the objective function considering the stiff ness-strength criteria. As a result, by optimizing the BRB cross-sectional area, the weight of BRBs will reduce. Two mostly-used cross-sectional profi les for all-steel BRBs (circular and rectangular) are considered. In general, the optimized solutions using AI algorithms were more cost eff ective and exhibited considerably better structural performance in terms of global buckling requirements in comparison to other conventional BRB designs. The results showed that BAT-PSO worked the best in terms of objective function value and computational time. The design solutions obtained using BAT-PSO were lighter (35% for circular profi les and 20% for rectangular profi les), and had superior performance in terms of both stiff ness and strength in comparison with the conventional BRB designs. It was also shown that using circular profi le can reduce the weight of BRB elements by around 15% compared to rectangular profi le. The results of this study should prove useful in more effi cient design of BRB systems in common practice.

Background: In recent years, an increased incidence of breast cancer has made this disease the most common malignancy among Iranian women. Since education plays an important role in the implementation of preventive behaviors in breast cancer treatment, this study investigates the effect of educational interventions on the promotion of lifestyle-related behaviors that prevent breast cancer in middle-aged women. Methods: In this randomized control study, 120 women referred to Neyshabur Health Services Centers were randomly selected and divided into two groups: an intervention group (60 subjects) and a control group (60 subjects). An educational intervention was carried out over five sessions, based on protective motivation theory constructs. Participants completed a researcher-designed questionnaire immediately and again 2 months after the intervention. The data were analyzed using IBM SPSS ver. 19.0 software (IBM Corp., Armonk, NY, USA). Results: The results revealed a significant difference between the mean scores of participants exposed to protective motivation theory, awareness, and physical activities immediately and also 2 months after the intervention (P<0.05). Although the healthy diet scores of the two groups differed significantly immediately after the educational intervention (P<0.05), there was no significant difference between the groups 2 months after the intervention (P<0.05). Conclusion: Given the effective role of education in protective motivation theory and the physical activity levels of the women who participated in this research, it seems clear that the women’s financial status shaped their ability to consume more fruits and vegetables. As this social element impacts the health of individuals, training programs alone cannot succeed.

Objective Recently, strong evidences were obtained on the association between low pregnancy-associated plasma protein-A (PAPP-A) levels in the first trimester and poor outcomes of pregnancy. Methods This cross-sectional study was conducted on all pregnant women who were referred to the Obstetrics and Gynecology Clinic at Imam Hossein Hospital in Tehran, Iran in 2014. Women were asked to attend clinical examinations and screening at 11-14 weeks of gestation. Results Based on the definition, 14.5% of neonates found to be small for gestational age (SGA). There was a strong association between PAPP-A levels and birth weight. The mean PAPP-A level in the mothers of neonates who were SGA was significantly lower than those without this poor outcome. Based on the receiver operating characteristic curve analysis, serum PAPP-A level was a main determinant in the prediction of SGA neonates. Conclusion The serum PAPP-A level at 11-13 weeks of gestation can effectively predict the increased risk for fetal growth retardation. In patients in this study, the best cutoff value for PAPP-A was 0.75 MOM, which signifies that lower levels of this marker can predict fetal growth restriction with high sensitivity and specificity.

Numerical Study of Influencing Factors on Tidal Wave Propagation in the Persian Gulf

S. Mahya Hoseini,Mohsen Soltanpour 한국해양과학기술원 2022 Ocean science journal Vol.57 No.4

A 2D hydrodynamic model is employed to study the characteristics of tidal wave propagation in the Persian Gulf (PG). The study indicates that tidal waves propagate from the Arabian Sea and the Gulf of Oman into the PG through the Strait of Hormuz. The numerical model is first validated using the measured water levels and current speeds around the PG and the principal tidal constituents of Admiralty tide tables. Considering the intermediate width of the PG, in comparison to the Rossby deformation radius, the tidal wave propagates like a Kelvin wave on the boundaries. Whereas the continental shelf oscillation resonance of the basin is close to the period of diurnal constituents, the results show that the tide is mixed mainly semidiurnal. A series of numerical tests is also developed to study the various effects of geometry and bathymetry of the PG, Coriolis force, and bed friction on tidal wave deformation. Numerical tests reveal that the Coriolis force, combined with the geometry of the gulf, results in the generation of different amphidromic systems of diurnal and semidiurnal constituents. The configuration of the bathymetry of the PG, with a shallow zone at the closed end of the basin that extends along its longitudinal axis in the southern half (asymmetrical cross section), results in the deformations of incoming and returning tidal Kelvin waves and consequently the shifts of amphidromic points (APs). The bed friction also results in the movements of the APs from the centerline to the south border of the gulf.
