The research paper aims to understand how globalization affects all sectors of education and instigates them to transform and change. Also, comprehending how Information and Communication Technologies (ICT) have the power to complement, enrich and positively transform education. This study finds that modern-day education reform and expansion needs to be regarded from the global contexts of decentralization and marketization perspectives. Likewise, the American Education System has been forced to reform rapidly in the past 3 decades, where it has seen many failures. Similarly, the use of ICT for active teaching has presented an efficient model in terms of integrating these technologies into teaching and learning practices. Additionally, teachers work in increasingly complex and diverse settings. Subsequently, this article serves as preliminary research that raises research questions on the impact of globalization and technology on education and the changing role of teachers and educators. Based on the above, this article suggests the adoption of the 4C’s of 21st century learning – collaboration, communication, creativity, and critical thinking, as a vital supplement to public education, educators and teachers in order to prepare students for future jobs. Teachers and educators play undoubtedly a fundamental role in the education transformation and improvements at the school or university level. In order to understand the changing role of the teachers in the 21st century, a study on the subjective world of the teacher as well as the analysis of the factors that influence the ever-changing global education is deemed necessary.

Rahimi, Zohreh,Yari, Kheirolah,Rahimi, Ziba Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.3

Background: Expression of matrix metalloproteinases (MMPs) is up-regulated in human cancers. The aim of present study was to investigate the role of MMP-9 C-1562T polymorphism and its interaction with MMP-2 C-735T polymorphism in susceptibility to breast cancer in a population from Western Iran with Kurdish ethnic background. Materials and Methods: The study sample of 205 individuals consisted of 101 breast cancer patients and 104 healthy subjects. MMP-9 C-1562T and MMP-2 C-735T variants were identified using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: Among 67.4% of studied patients the breast cancer developed in the third and forth decades of the life. The frequency of MMP-9 T allele was 17.3% in patients and 10.1% in controls. The presence of T allele significantly increased the risk of breast cancer by 1.87-fold [OR=1.87 (95% CI 1.05-3.33, p=0.035)]. The frequency of MMP-9 CT+TT genotype tended to be higher in those patients with a family history of cancer in first degree-relatives (36.8%) than those without a family history (28.3%, p=0.37). We observed an interaction between the MMP-9 -1562 T allele with MMP-2 -735 C allele that significantly increased the risk of breast cancer [OR=1.42 (95% CI 1.02-1.98, p=0.036)]. Conclusions: The present study demonstrated that MMP-9 C-1562T polymorphism alone and in combination with MMP-2 C-735T polymorphism increased the risk of breast cancer that might be a useful biomarker in identifying women at risk of developing breast cancer. Also, this study revealed that in most women from Western Iran breast cancer presents in third and fourth decades of life.

Background: Cancer is a major public health problem and the leading cause of mortality in both males and females in developed and developing countries. The incidence of cancer is gender dependent. Among Iranians, it is the third cause of death. Materials and Methods: The information recorded in the files of all patients (7,695 individuals) pathologically diagnosed with cancer in Imam Reza referral hospital of Kermanshah University of Medical Sciences during the four year period of 2006-2009 were reviewed and analyzed using SPSS statistical software package version 16.0. Results: Around 61.6% of reported cancer cases were males and 38.4% were females. The most prevalent reported malignant tumors occurred at the age group of 70-79 years in males and in females these tumors were presented in the ages of 60-69 years. The most prevalent cancers among studied patients were gastrointestinal (GI) cancers with a frequency of 22.9% [gastric 10.7%, colorectal 6.9%, and esophageal 6%]. The second, third and forth prevalent cancers were blood at 16.4%, lung 13.5% and bladder 12.8%, respectively. In males the cancers of GI (25.6%) were the most prevalent followed in order of frequency by bladder (18%), blood (17.6%), lung (17.4%) and prostate (6.8%). In females the most frequent recorded cancer was breast (24.1%) followed in order of frequency by GI (20.5%), blood (14.4%), lung (7.3%), uterus (6.2%) and ovary (5.1%). Breast cancer was the most prevalent cancer (27%) in the age group of 40-49 years. Conclusions: The present study provides frequency data for various types of cancers in both males and females from a referral hospital of Kermanshah that are comparable with some reports from other areas of the country.

A predictive mechanoluminescence transduction model for thin-film SrAl₂O₄:Eu²⁺, Dy³⁺ (SAOED) stress sensor

Rahimi, M.R.,Yun, G.J.,Choi, J.S. Elsevier Science 2014 Acta materialia Vol.77 No.-

This paper proposes a phenomenological stress-optics transduction model for predicting mechanoluminescence (ML) light intensity from a thin-film ML coating sensor subjected to in-plane stresses. Recent findings on the considerable effects of persistent luminescence (PL) decay on ML phenomena (Rahimi MR, Yun GJ, Doll GL, Choi JS. Opt Lett 2013;38:193235) have motivated the incorporation of critical factors (i.e. strain rate, stress-free PL decay time interval, photoexcitation time, instantaneous PL decay rate, etc.) into a predictive ML transduction model. In the proposed model, the total ML+PL light emission is subdivided into a net ML emission, stress-free PL decay, and additional stress-induced PL decay. These are separately modeled and combined on the basis of interaction of the ML phenomena with PL decay and the effects of strain rates and PL decay time intervals. Predictions by the proposed model were found to agree well with experimental results. The relative total ML+PL light intensity was also proven to be linearly proportional to the mechanical strain energy. The proposed predictive model can be broadly used in the design of ML sensing film and in applications for the calibration process.

Estimation of Genetic Variation in Holstein Young Bulls of Iran AI Station Using Molecular Markers

Rahimi, G.,Nejati-Javaremi, A.,Saneei, D.,Olek, K. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.4

Genetic profiles of Iranian Holstein young bulls at the national artificial insemination station were determined on the basis of individual genotypes at 13 ISAG's recommended microsatellites, the most useful markers of choice for parentage identification. In the present study a total of 119 individuals were genotyped at 13 microsatellite loci and for possible parent-offspring combinations. A high level of genetic variation was evident within the investigated individuals as assessed from various genetic diversity measures. The mean number of observed alleles per microsatellite marker was 9.15 and the number of effective alleles as usual was less than the observed values (4.03). The average observed and expected heterozygosity values were 0.612 and 0.898, respectively. The mean polymorphic information content (PIC) value (0.694) further reflected a high level of genetic variability. The average exclusion of probability (PE) of the 13 markers was 0.520, ranging from 0.389 to 0.788. The combined exclusion of probability was 0.999, when 13 microsatellite loci were used for analysis in the individual identification system. Inbreeding was calculated as the difference between observed and expected heterozygosity. Observed homozygosity was less than expected which reflects inbreeding of -3.7% indicating that there are genetic differences between bull-sires and bull-dams used to produce young bulls. The results obtained from this study demonstrate that the microsatellite DNA markers used in the present DNA typing are useful and sufficient for individual identification and parentage verification without accurate pedigree information.

PollMap: a software for crop pollination mapping in agricultural landscapes

Rahimi, Ehsan,Barghjelveh, Shahindokht,Dong, Pinliang,Pirlar, Maghsoud Arshadi,Jahanbakhshian, Mohammad Mehdi The Ecological Society of Korea 2021 Journal of Ecology and Environment Vol.45 No.1

Background: Ecosystem service mapping is an important tool for decision-making in landscape planning and natural resource management. Today, pollination service mapping is based on the Lonsdorf model (InVEST software) that determines the availability of nesting and floral resources for each land cover and estimates pollination according to the foraging range of the desired species. However, it is argued that the Lonsdorf model has significant limitations in estimating pollination in a landscape that can affect the results of this model. Results: This paper presents a free software, named PollMap, that does not have the limitations of the Lonsdorf model. PollMap estimates the pollination service according to a modified version of the Lonsdorf model and assumes that only cells within the flight range of bees are important in the pollination mapping. This software is produced for estimating and mapping crop pollination in agricultural landscapes. The main assumption of this software is that in the agricultural landscapes, which are dominated by forest and agriculture ecosystems, forest patches serve only as a nesting habitat for wild bees and the surrounding fields provide floral resources. Conclusion: The present study provided new software for mapping crop pollination in agricultural landscapes that does not have the limitations of the Lonsdorf model. We showed that the use of the Lonsdorf model for pollination mapping requires attention to the limitations of this model, and by removing these limitations, we will need new software to obtain a reliable mapping of pollination in agricultural landscapes.

Rahimi, Shadi,Kim, Jaewook,Mijakovic, Ivan,Jung, Ki-Hong,Choi, Giltsu,Kim, Sun-Chang,Kim, Yu-Jin Elsevier 2019 BIOTECHNOLOGY ADVANCES Vol.37 No.7

<P><B>Abstract</B></P> <P>Triterpenoid saponins are naturally occurring structurally diverse glycosides of triterpenes that are widely distributed among plant species. Great interest has been expressed by pharmaceutical and agriculture industries for the glycosylation of triterpenes. Such modifications alter their taste and bio-absorbability, affect their intra−/extracellular transport and storage in plants, and induce novel biological activities in the human body. Uridine diphosphate (UDP)-glycosyltransferases (UGTs) catalyze glycosylation using UDP sugar donors. These enzymes belong to a multigene family and recognize diverse natural products, including triterpenes, as the acceptor molecules. For this review, we collected and analyzed all of the UGT sequences found in <I>Arabidopsis thaliana</I> as well as 31 other species of triterpene-producing plants. To identify potential UGTs with novel functions in triterpene glycosylation, we screened and classified those candidates based on similarity with UGTs from <I>Panax ginseng</I>, <I>Glycine</I> max, <I>Medicago truncatula</I>, <I>Saponaria vaccaria</I>, and <I>Barbarea vulgaris</I> that are known to function in glycosylate triterpenes. We highlight recent findings on UGT inducibility by methyl jasmonate, tissue-specific expression, and subcellular localization, while also describing their catalytic activity in terms of regioselectivity for potential key UGTs dedicated to triterpene glycosylation in plants. Discovering these new UGTs expands our capacity to manipulate the biological and physicochemical properties of such valuable molecules.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Potential triterpene-related UGT candidates are classified based on the similarity with the UGTs with known function in triterpene glycosylation. </LI> <LI> Substrate specificities are suggested among triterpene biosynthesis UGT candidates. </LI> <LI> UGTs grouping based on PSPG motif involved in sugar donor specificity is presented. </LI> <LI> MeJA inducibility, physiological function, tissue expression, catalytic characteristics of triterpene biosynthesis UGTs are discussed. </LI> <LI> Regioselectivity and catalytic characteristic of triterpene biosynthesis UGTs are described. </LI> </UL> </P>
