Background: Self-regulation learning (SRLS) and emotional intelligence constructs among youth considering effectiveness and enhancement of optimization and quality of life. M aterials and Methods: The research sample composed of 200 students who studied at Iranian universities in 2016-17 academic year. SRLS and Goleman's emotional intelligence questionnaire were utilized in this research. Collected data was analyzed using Pearson’s correlation coefficient and multivariate regression technique. R es ults: Scores of goal setting and planning (p=0.009) and self-consequating (p=0.021) were higher among females, and those of support from teacher (p=0.014), notes review (p=0.001), and homework review (p=0.004) were higher among males. Furthermore, regarding emotional intelligence, scores of self-motivation (p=0.012) and social skills (p=0.008) were higher among males. Conclusion: Goal-setting and planning for these strategies help people organize materials more easily, and understand that, self-consequating includes learner’s judgement about his/her own capabilities, and this self-trust contributes to better implementation of his/her cognitive skills in his/her studies. Regarding the support from teacher, notes review and homework review among males, which fall within the scope of resource management strategies, by organizing learning environment, seeking support from parents and teacher, and adjusting efforts help the learner either eliminate or attenuate distraction, and the fact that others can help us. Furthermore, both note taking and note reading contribute to better recovery of information from memory. This strategy includes administrating or regulating one’s own and others’ emotions, appropriate adoption of those in human relationships, controlling instantaneous desires, and confronting opposite or negative emotions. Being composed of self-motivation and social skills, this strategy has higher levels among males.
背景:青少年自我调节学习(SRLS)和情绪智力的建构考虑了优化和提高生活质量的有效性。材料与方法:研究样本由2016-17学年在伊朗大学学习的200名学生组成。本研究采用SRLS问卷和Goleman情绪智力问卷。采用Pearson相关系数和多元回归技术对收集的数据进行分析。结果:女性在目标设定与计划(p=0.009)和自我结果(p=0.021)得分较高,男性在教师支持(p=0.014)、笔记复习(p=0.001)和作业复习(p=0.004)得分较高。此外,在情绪智力方面,男性的自我激励得分(p=0.012)和社交技能得分(p=0.008)更高。结论:这些策略的目标设定和计划帮助人们更容易地组织材料,并且理解自我推理包括学习者对自己能力的判断,这种自信有助于更好地实施他/她的学习认知技能。对于教师的支持,男性的笔记复习和作业复习属于资源管理策略的范畴,通过组织学习环境,寻求家长和老师的支持,调整努力,帮助学习者消除或减弱分心,以及他人可以帮助我们的事实。此外,记笔记和读笔记都有助于更好地从记忆中恢复信息。这种策略包括管理或调节自己和他人的情绪,适当地采用人际关系中的情绪,控制瞬时的欲望,面对相反的或消极的情绪。这种策略由自我激励和社交技巧组成,在男性中更为普遍。

Background: Here we assessed the incidence of Influenza-A-H1N1-related pneumonia in community-acquired pneumonia (CAP) at Loghman Hakim Hospital, Tehran, Iran. M aterials and Methods: In this prospective study from November 22, 2016, to June 21, 2017, patients with CAP and suspected to seasonal influenza were included. Rapid Antigen test and quantitative real-time PCR assay were performed on samples. P-value < 0.05 was considered significant. In addition, radiologic patterns of them were evaluated. R es ults: a total of 29 admitted CAP patients were suspected of seasonal influenza. Two cases out of them were positive for influenza by real-time PCR, similar to result of influenza rapid test. The most common finding in their chest X ray was consolidation in one lobe. None of them vaccinated against influenza. Only nine patients received empiric Oseltamivir treatment. The amount of irrational antibiotic administration was significant. C onclusion: Despite low statistical numbers, admitted influenza CAP patients did not have unusual symptoms and radiologic patterns. Other results in this study showed need for antibiotic stewardship program and better training about necessity of vaccination.

Background: Alar base surgery is one of the controversial issues in rhinoplasty. In this surgery the nasal base width and alar flaring is got smaller with some kind of procedures. One of these procedures is wedge resection of alar base. This procedure may accompany with either some dissatisfaction of scars and adverse effects or complications. In this study, we evaluate the patient satisfaction of scar and possible complications. Materials and Methods: A total of 120 rhinoplasty patients at 15 khordad hospital were candidates for alar base wedge resection due to broad nasal base and / or alar flaring who were chosen for this study. We recorded and examined these patients before and minimum 6 months after surgery, then evaluated these information and data, which finally, compared all the preoperation and postoperation findings. Results: Mean age of patients was 30.11 years old. The full satisfaction of scar was 85.5% (103), but 6.7% (8) of patients had not satisfaction of scar due to visible scar in their alar facial groove. The rate of nostril symmetry satisfaction was 79.2% (95) and 8.3% (10) was dissatisfied due to nostril asymmetry. There was no external valve incompetency nor alar and sill notching in our study. There was not any narrowing of nostrils as well. The mean interalar distance preoperatively was 35.88 mm, which reduced to 32.61mm of mean diameter after surgery, (P-value = 0.000). Alar flaring correction was 88% (106) which was an acceptable consequence. Conclusion: The results of present study showed that in spite of surgeons fear for scar and some common complications after alar base resection, the satisfaction rate of our patients in this study were high, and complications frequencies were low. Therefore, we advise that it is better and wiser to do this operation in indicated patients surely within primary rhinoplasty and do not postpone it to another surgery.
背景:鼻翼底手术是鼻整形中有争议的问题之一。在这个手术中鼻底的宽度和鼻翼的扩张通过某种方法变小了。其中一种手术是鼻翼基部楔形切除。这种手术可能伴随一些疤痕的不满意和不良反应或并发症。在这项研究中,我们评估患者对疤痕的满意度和可能的并发症。材料和方法:本研究选取了15家khordad医院的120例鼻整形患者,这些患者因鼻基底宽和/或鼻翼突出而选择鼻翼基底楔形切除术。我们记录和检查这些患者术前和术后至少6个月,然后评估这些信息和数据,最后比较所有术前和术后的结果。结果:患者平均年龄30.11岁。瘢痕完全满意率为85.5%(103例),但有6.7%(8例)患者因鼻翼面沟可见瘢痕而对瘢痕不满意。鼻孔对称满意率为79.2%(95例),因鼻孔不对称不满意者为8.3%(10例)。本研究未见外瓣膜功能不全,也未见鼻翼和缺口。鼻孔也没有缩窄。术前平均指间距为35.88 mm,术后平均指间距降至32.61mm,差异有统计学意义(p = 0.000)。鼻翼扩张矫正率为88%(106),这是可接受的结果。结论:本研究结果表明,尽管外科医生担心鼻翼底切除术后会出现疤痕和一些常见的并发症,但本研究患者的满意率高,并发症发生率低。因此,我们建议在初次鼻成形术的适应症患者进行此手术是更好和更明智的,而不是推迟到另一次手术。

Background: Hot mix asphalt (HMA) is one of the most important structures to implement the road and street surfaces, which always exposed to destruction. Provide new solutions to reduce the destructive process of effective factors on asphalt destruction and increasing prolong of its lifetime is important for society of road engineers. Traffic loading and weather conditions are the major factors that have role on different asphalt destruction. M aterials and Methods: In this study, three types of HMAs, which contain nanoclay, and carbon nanotubes were produced by Marshall method in Iran University of Science and Technology, and one type of aged HMA were also collected for further investigations. The HMA samples were transferred to microbiology laboratory of Shahid Beheshti University of Medical Sciences, and then suspensions were prepared from specimens and cultured on nutrient agar medium. After 24 hours’ incubation at 37 C the bacteria that were grown on the plate were identified. At least the effect of clay and carbon nanoparticles on minimum inhibitory concentration (MIC) of bacteria, were determined by microdilution broth method. R es ults: A lot of bacterial colonies ( Bacillus and Pseudomonas ) were collected from the aged specimens. The asphalt, which contain nanoclay had more bacteria than the nanocarbon asphalt. The carbon and clay nanoparticles in 2% and 4% concentration prevented the growth of bacteria, respectively. C onclusion: The old asphalt had more bacteria than other samples, which shows bacteria are one of the main factors in decomposition of asphalt by applying corrosion to bituminous hydrocarbons. Presence of clay and carbon nanoparticles in asphalt structures could increase the durability of the HMAs and reduce the relevant economics costs.
背景:热混合沥青(HMA)是实现道路和街道表面最重要的结构之一,它总是暴露在破坏中。为减少影响沥青破坏的有效因素的破坏过程,延长沥青的使用寿命提供新的解决方案,对道路工程人员具有重要的社会意义。交通荷载和天气条件是影响沥青破坏的主要因素。材料与方法:本研究在伊朗科技大学采用马歇尔法制备了三种含纳米粘土和碳纳米管的HMA,并收集了一种老化的HMA进行进一步研究。将HMA样品转移至Shahid Beheshti医科大学微生物实验室,制备悬浮液,在营养琼脂培养基上培养。37℃孵育24小时后,鉴定出在培养皿上生长的细菌。采用微量稀释肉汤法测定了粘土和纳米碳对细菌最低抑菌浓度的影响。结果:采集到大量菌落(芽孢杆菌和假单胞菌)。含有纳米粘土的沥青比含有纳米碳的沥青有更多的细菌。碳纳米颗粒和粘土纳米颗粒的浓度分别为2%和4%,可以抑制细菌的生长。C结论:旧沥青中细菌含量高于其他样品,说明细菌是通过腐蚀沥青碳氢化合物来分解沥青的主要因素之一。在沥青结构中加入粘土和纳米碳颗粒可以提高hma的耐久性,并降低相关的经济成本。

Background: Many studies have shown a high prevalence of vitamin D deficiency in different communities. Due to multiple roles of vitamin D in the body, this study was aimed to determine the effect of oral vitamin D3 on ventilatory threshold-1 in a condition of vitamin D deficiency. M aterials and Methods: Recent study performed on 25 healthy young adults with the serum levels of 25 Hydroxyvitamin D3 lower than 20 ng/ml, had referred to the sports medicine clinic of Taleghani Hospital of Tehran, in a one-year period (2016-2017). After primary evaluation, baseline ventilatory threshold-1 were determined by cardiopulmonary exercise testing (CPET). Then persons were treated with 50,000 IU/week of oral vitamin D3 for 8 weeks, and one week after the completion of treatment, ventilator threshold-1 was measured again, similar to the beginning conditions of the study, and its changes were studied. R es ults: The mean baseline ventilatory threshold-1 of participants before any intervention was 22.46 ± 6.45 (ml/kg/min), and after 8 weeks of treatment by 50000 IU/week of oral vitamin D3, increased to 26.79 ± 5.33 (ml/kg/min) at the end of study, which there was a statistically significant increase in ventilatory threshold-1 (p<0.001). C onclusion: Recent study showed that proper treatment of the vitamin D deficiency, improves ventilatory threshold-1 in healthy young adults.
背景:许多研究表明,维生素D缺乏症在不同社区的患病率很高。由于维生素D在体内的多重作用,本研究旨在确定维生素D缺乏情况下口服维生素D3对通气阈值-1的影响。材料和方法:最近对25名健康青年进行了一项为期一年(2016-2017)的研究,他们的血清25羟维生素D3水平低于20 ng/ml,已转至德黑兰Taleghani医院运动医学诊所。初步评估后,通过心肺运动试验(CPET)确定基线通气阈值。然后患者口服5万IU/周维生素D3治疗8周,治疗结束1周后再次测量呼吸机阈值-1,与研究开始时的条件相似,并研究其变化。结果:干预前受试者的平均基线通气阈值-1为22.46±6.45 (ml/kg/min),口服维生素D3 5万IU/周治疗8周后,研究结束时通气阈值-1增加至26.79±5.33 (ml/kg/min),通气阈值-1增加有统计学意义(p<0.001)。结论:最近的研究表明,适当治疗维生素D缺乏症,可提高健康年轻人的通气阈值1。
