Investigating the Validity of Student’s Portfolio in Classroom Assessment at the First Secondary Class in the Kingdom of Bahrain
Authors: Aldoseri Rashed H.
Published: August 2017

This research aimed to investigate the validity of the secondary student's portfolio by utilizing Messick's six-facet unified model of validity (content, structure, generalizability, external, substantive, consequences), as well as exploring teachers’ practices in using student’s portfolio for assessing students' achievement. The research was applied in two secondary schools in Bahrain, one for males and one for females. A random sample of 30 teachers from 130 teachers participated in the study. Two instruments were used: a 20-item questionnaire pertaining to teachers’ classroom assessment practices; and a 22-item form about the content of students' portfolio, with five dimensions. The results revealed that most teachers' assessment practices of the portfolio focused on students' activities and projects. Also, assigning grades to the students was another priority of teachers. Evidence of validity of students' portfolio in assessment according to Messick’s model was found. Inter-correlations ranged between 0.63 to 0.85; and reliability coefficients ranged from 0.84 to 0.92 among the 5 dimensions of the student portfolio. Regarding the generalizability validity, 47% of the variance of students’ scores in the portfolio is attributed to raters’ judgments about the relevance of portfolio components. Moreover, the results indicated evidence of the generalizability validity of the portfolio as depicted in the relationship between students' portfolio scores and students' GPA (r = 0.75) and between students' portfolio and students' scores in the national exam (r = 0.68). The researcher provided suggestions for further research.

Authors: Abd-El-Fattah Sabry M.
Published: August 2017

This study aimed at examining the psychometric properties of the Perceived Physical Ability Scale for Children (PPASC) within an Omani context. A sample of 250 fourth graders (130 males and 120 females) from six public primary schools in four governorates in Oman responded to Arabic translated version of the PPASC. Data on students' in-class physical activity, social desirability, and teachers' nominations of students' physical ability were also collected. Confirmatory factor analysis revealed that the unidimensional model of the PPASC had adequate fit to the data. Multigroup CFA revealed gender invariance for PPASC unidimensional model when it was compared across male and female groups. A latent mean analysis showed that there were significant gender differences in perceived physical ability favoring males. The PPASC correlated positively with in-class physical activity and teachers' nominations of students' physical ability but not with social desirability.

Published: August 2017

Alucinógenos são agentes químicos que induzem alterações na percepção, no pensamento e nas emoções. Entre os alucinógenos naturais há a ayahuasca, originalmente utilizada por tribos indígenas da Amazônia, preparada com a mistura de duas plantas: Banisteriopsis caapi, que contém β-carbolinas, um inibidor da monoamina oxidase (MAO), e Psychotria viridis, rica em N,N-dimetiltriptamina (DMT), que atua nos receptores serotoninérgicos. Atualmente, o uso do chá de ayahuasca se espalhou por diversas regiões do mundo, e diferentes religiões, tais como União do Vegetal, Santo Daime e Barquinha, fazem seu uso ritualístico. Este estudo relata um caso sobre sintomatologia psicótica e uso da ayahuasca. Trata-se de uma paciente jovem, admitida por quadro de isolamento social, prejuízo do autocuidado e delírio bizarro, iniciado há 3 anos, com piora gradual. Era membra da União do Vegetal e fazia uso frequente de ayahuasca. Durante a internação, foi feito o diagnóstico de esquizofrenia, e a paciente melhorou com eletroconvulsoterapia. Pesquisas recentes demonstram que as manifestações clínicas dos alucinógenos se assemelham às da esquizofrenia. Por isso, experimentos farmacológicos com alucinógenos são rrequentemente usados como modelos de psicose.

Published: August 2017

Este artigo resume as pesquisas entre 2014 e 2016 pertinentes às diferenças em cuidados clínicos e neurobiologia de mulheres e homens com transtorno afetivo bipolar (TAB). Com TAB, o sexo feminino se correlaciona com mais sintomas depressivos e diferentes comorbidades. As mulheres também têm um maior grau de episódios mistos e ciclagem rápida. Quanto a comorbidades, doença da tireoide, obesidade e transtornos de ansiedade ocorrem mais frequentemente em mulheres, enquanto transtornos por uso de substância são mais comuns em homens. O exercício aumenta os níveis do fator neurotrófico derivado do cérebro em mulheres bipolares, mas não em homens. Pacientes do sexo masculino e do sexo feminino têm biomarcadores distintos para o TAB. Alterações menstruais e flutuação de humor estão presentes em mulheres tratadas para o TAB em um grau maior do que nos controles. Lamotrigina pode ser útil para atenuar essa flutuação. A desregulação da tireoide associada ao lítio ocorre mais frequentemente em pacientes do sexo feminino. Homens e mulheres com TAB recebem tratamentos diferentes em ambientes clínicos de rotina. Decisões clínicas de tratamento são, em certa medida, indevidamente influenciadas pelo sexo dos pacientes.

Authors: Santi Iga
Published: August 2017

This paper aims to examine non-physical loss in land procurement based on justice value. This study was conducted considering many problems arising from the current phenomenon in which people of Indonesia have not got their rights fairly. Whereas in the mandate of Constitution Article 33 of the 1945 Constitution states that the earth and water and natural resources contained therein are controlled by the state and used for the greatest prosperity of the people. The primary data was obtained from direct interviews with related parties, while secondary data were obtained from literature study. The result shows that people's behavior is strongly influenced by the culture exists in society. The culture of society includes religious values and social values. Government recognition by paying attention to the values in society in the determination of non-physical compensation will prevent prolonged conflicts that occur in the process of land acquisition for the public interest, and there are still many articles that need to be reviewed that immediately review the Article 33 letter f, Article 42 Paragraph 1 jo Article 43 UUPT Year 2012 to better reflect justice for eligible citizens and communities affected by development for the public interest.
Stand und Perspektiven der Additiven Fertigung
Authors: Gausemeier Jürgen , Kage Martin
Published: August 2017

Kurzfassung

Neben Industrie 4.0 hat kaum ein anderes Technologiefeld jüngst eine vergleichbare Aufmerksamkeit erhalten wie Additive Fertigung. Noch immer klaffen die Erwartungshaltung und die Leistungsfähigkeit der Technologien auseinander; mittlerweile ist eine realistischere Sichtweise auf das Technologiefeld zu verzeichnen. Derzeit gibt es keine belastbaren Indikatoren dafür, dass Additive Fertigung die industrielle Produktion revolutionieren wird. Dennoch verzeichnet das Technologiefeld beachtliche Wachstumsraten und ist Gegenstand reger Übernahmeaktivitäten. Noch ist Deutschland erstklassig positioniert: Führende Anbieter, Dienstleister und Forschungsinstitutionen stammen aus Deutschland. In Anbetracht der sich abzeichnenden Entwicklungen müssen jedoch Rahmenbedingungen für die Additive Fertigung justiert werden, um Deutschlands technologische Spitzenposition zu erhalten und weiter auszubauen.

Authors: Kherroub Djamal Eddine , Belbachir Mohammed , Lamouri Saad , Bouhadjar Larbi , Chikh Karim
Published: August 2017

In this study, a new and easy strategy was discussed for the purpose of synthesizing of a polymer of phenylmethylcyclosiloxane type (PPMS). The cationic ring opening polymerization of triphenyltrimethylcyclotrisiloxane (D3Ph,Me) was initiated by a solid, efficient and environmentally-friendly catalyst called Maghnite-H+. Maghnite-H+ is a natural clay composed essentially of montmorillonite, it is activated with an acid treatment by replacing the interlayer ions by protons, that results to the increase of the basal space, this may be confirmed by XRD analysis. The reaction was carried out without solvent at different temperatures and for different periods of time, using also several catalyst contents. Subsequently, the operating conditions were opted in order to obtain a maximum yield of the linear polymer and a high average molecular mass as well. The structure of polymers obtained was confirmed by IR analysis. 1H NMR and 13C NMR analyzes were used to follow the crosslinking of polymer chains over time. The thermal behavior was investigated by DSC analysis. The average molecular mass and the polydispersity indices were determined by GPC.

Authors: Zahan Gulsan Ara , Mosleh Taskina , Akter Khaleda , Bari Iqbal , Mannan MA , Maleq Abdul
Published: August 2017

Background: Premature infant mortality & morbidity is influenced by intrauterine growth & maturation. In our perspective unavailability of accurate LMP from mother, early USG report or home delivered preterm baby that admitted after 4th day of postnatal age create great dilemma regarding the assessment of gestational age (GA).Objective: To validate the New Ballard Score (NBS) until 7th day of postnatal age in preterm neonate.Methods: This observational cross sectional study was conducted in pediatric ward, Rajshahi Medical College Hospital from 1st January 2009 to 31st December 2009. A total of 129 preterm neonate, GA ranging from 29wk to 35 wk, without any medical problem were included in this study. Accurate documentation of LMP of mother and USG during early pregnancy period were available for each study sample. GA of the babies were determined by NBS on 1st, 5th and 7th postnatal age and compaired with LMP & USG based GA. Various raw score was obtained from broken total score in D1 compared with D5 & D7. LMP based GA also compared with USG based GA.Results: Total NBS of D1 were tested with D5 & D7 for level of agreement & degree of correlation. For D1 with D5, r value was 0.97 and for D1 with D7, r value was 0.681. So, NBS of D1 positively correlated with NBS of D5 and D7. The total physical score also positively correlated with D1 versus D5 & D7 (r value 0.975 & 0.796). The total neurological score positively correlated with D1 versus D5 & D7 (r value 0.893 & 0.630). Neurological score were more significant than physical score. All p values were statistically significant (p value ?0.001). GA by NBS & LMP was positively correlated (r=0.94) as well as GA by NBS & USG (r=0.94). GA by NBS did not differ more than 2 weeks from LMP or USG based GA of any particular subjects.Conclusions: The tendency of over estimates the GA by NBS increased from Day 1 to Day 5 to Day 7. But the GA calculated from LMP & USG did not differ more than 2 weeks from GA by NBS. Thus NBS can be used as a clinical tool to detect GA up to Day 7 of postnatal life.Bangladesh J Child Health 2017; VOL 41 (1) :24-27

Published: August 2017

Background: Variceal bleeding is often a life threatening clinical situation in infants and children. Band ligation is the main endoscopic treatment for esophageal varices.Objective: To see the outcome of band ligation of esophageal varices in extra-hepatic and hepatic cases of portal hypertension.Methods: This prospective study was done in the Department of Pediatric Gastroenterology, Hepatology & Nutrition, Dhaka Shishu (Children) Hospital, Dhaka, Bangladesh on 40 consecutive cases of esophageal varices enrolled from April, 2014 to March 2016. Every case was treated with band ligation followed by tab. propranolol. Cases were followed up for a minimum period of one year after the band ligation.Results: Age of the children was 2-12 years with mean age of 7.2±4.3 years and male:female ratio was 1.5:1. Out of 40 children, 32 (80%) were pre-hepatic and 8 (20%) hepatic (chronic liver disease with portal hypertension) causes. Only 1 session required in 50% pre-hepatic cases and multiple (2-3) sessions required in hepatic (100%) cases. Almost same number of band (average 2-3) required in every session of both cases. Grade-II esophageal varices with red sign were more common in prehepatic cases & severity of grading much more (grade-III & IV) in hepatic cases. Gastric varices were more common in hepatic (50%) cases than extra-hepatic (12.5%) cases. Recurrence of bleeding occurred in all hepatic (100%) cases and half (50%) of the pre-hepatic cases. Early re-bleeding was more common in hepatic (75%) cases & late re-bleeding in both pre-hepatic (43.7%) & hepatic (100%) cases. Minimal side effect like discomfort (10%) & Nausea (10%) were present after the procedure.Conclusion: Pre-hepatic was the most common etiology of portal hypertension in studied children. Fewer sessions were required in pre-hepatic cases than in hepatic cases. Severity of grading, re-bleeding & associated gastric varices were more common in hepatic cases. Band ligation was found to be the treatment of choice for the control of acute variceal bleeding and prevention of re-bleeding with less complications.Bangladesh J Child Health 2017; VOL 41 (1) :28-33
Noninherited Risk Factors of Congenital Heart Defects in Offspring: A Revi
Authors: Mamun Mohammad Abdullah Al , Hussain Manzoor , Hasan Mohammad Nurul Akhtar , Rima Rezoana
Published: August 2017

Prognosis of children with congenital heart defects (CHDs) continues to improve with advancement in technology and training in pediatric cardiology and cardiac surgery; however, lack of information about risk factors for malformations in cardiovascular development impeded the prevention of CHDs. Etiology of CHDs are complex and possibly lies within the interaction of environmental exposures and inherited factors. Studies found multiple maternal environmental exposures, including living in newly renovated rooms, residential proximity to main traffic, smoking and maternal occupation as manual worker significantly associated with CHDs. Advanced maternal age, low socioeconomic status, maternal perinatal diseases including maternal fever, diabetes, influenza, maternal certain medication use and alcohol intake were also significantly associated with CHDs. Isolated CHDs and multiple defects have different profiles of risk factors, while subtype of CHDs share common risk factors. Because of differences in methods, these studies are only suggestive. Relatively less information has been reported on noninherited factors that may have an adverse effect on the cardiovascular development, which has made it difficult to create population-based strategies to reduce the burden of illness from CHDs and for couples to choose lifestyles to reduce the risk of delivering a child with CHDs.Bangladesh J Child Health 2017; VOL 41 (1) :40-52

The aim of this study was to examine the anti-proliferation and anti-migration effect of Centipede Scolopendra extracts (CSE) on human epidermoid carcinoma cells (high-EGFR expression) A431 and elucidate the underlying signaling mechanisms. MTT and colony formation assays were used. Migration and invasion potential of A431 cells were examined by wound-healing assays and matrigel invasion chamber assays. To investigate the underlying molecular mechanisms, we used ELISA to analyze the expression of EGF, Western blotting to analyze the expression of MMP2 (matrix metalloproteinase 2), MMP9 and EGFR, PCR to analyze the mRNA expression of EGFR pretreated with CSE. The results showed that CSE effectively inhibited the proliferation of A431. Furthermore, CSE-mediated cell cycle arrest in S phase. We also observed that CSE treatment led to down-regulation of MMP2 and MMP9 and suppress the migration and invasion in A431. CSE exerted its anti-proliferation and anti-migration by targeting EGFR and related metastasis factors, thus could be a useful therapeutic candidate for high-EGFR expression cancer intervention.

Published: August 2017

Background: Medical professionalism can be defined as a set of values, behaviours and relationships. Thus it is imperative that professionalism is incorporated into the undergraduate curriculum. In Universiti Sains Islam Malaysia, medical professionalism is integrated throughout the 6-year medical programme through courses in Fundamental Islamic knowledge, Medical ethics, clinical teaching and community sessions.Objective: Thus a study was carried out to evaluate the perception of the concept of professionalism among clinical students.Materials and Methods: A cross-sectional study was carried out on 142 clinical students of year 4, year 5 and year 6. Participants were given a questionnaire consisting of items on personality and professional characteristics of a good Muslim doctor. Analysis of data was done using SPSS software version 18. The mean, standard deviation, mean score, median and inter quartile ranges (IR) for knowledge, attitude, practice as well as both personal and professional characteristics were determined and the differences between groups were analysed using Mann-Whitney U tests or T tests.Results: Significant differences were seen for perception of professional characteristics between year 4 and year 6 (p value = 0.0001) and between year 5 and year 6 (p value=0.002). Significant differences for all items on professional characteristics were seen between year 4 and the final year students and four out of five items between year 5 and the final year students. No significant differences were noted in the perception of personal and professional characteristics among the clinical students by gender.Conclusion: The clinical students seemed to have benefitted from the Islamic-integrated medical curriculum in USIM. Overall, the senior clinical students developed better insight of the desirable personal and professional characteristics of a good Muslim doctor. Improvement in the teaching of professionalism could have greater impact on the development of professionalism among the clinical students.J MEDICINE July 2017; 18 (2) : 56-61
Toward the Selection of Cell Targeting Aptamers with Extended Biological Functionalities to Facilitate Endosomal Escape of Cargoes

Published: August 2017

Over the past decades there have been exciting and rapid developments of highly specific molecules to bind cancer antigens that are overexpressed on the surfaces of malignant cells. Nanomedicine aims to exploit these ligands to generate nanoscale platforms for targeted cancer therapy, and to do so with negligible off-target effects. Aptamers are structured nucleic acids that bind to defined molecular targets ranging from small molecules and proteins to whole cells or viruses. They are selected through an iterative process of amplification and enrichment called SELEX (systematic evolution of ligands by exponential enrichment), in which a combinatorial oligonucleotide library is exposed to the target of interest for several repetitive rounds. Nucleic acid ligands able to bind and internalize into malignant cells have been extensively used as tools for targeted delivery of therapeutic payloads both in vitro and in vivo. However, current cell targeting aptamer platforms suffer from limitations that have slowed their translation to the clinic. This is especially true for applications in which the cargo must reach the cytosol to exert its biological activity, as only a small percentage of the endocytosed cargo is typically able to translocate into the cytosol. Innovative technologies and selection strategies are required to enhance cytoplasmic delivery. In this review, we describe current selection methods used to generate aptamers that target cancer cells, and we highlight some of the factors that affect productive endosomal escape of cargoes. We also give an overview of the most promising strategies utilized to improve and monitor endosomal escape of therapeutic cargoes. The methods we highlight exploit tools and technologies that can potentially be incorporated in the SELEX process. Innovative selection protocols may identify aptamers with extended biological functionalities that allow effective cytosolic translocation of therapeutics. This in turn may facilitate successful translation of these platforms into clinical applications.

Published: August 2017

To elucidate the atomic arrangement of a Pt-Rh-Sn ternary catalyst with a high catalytic activity for ethanol oxidation reaction (EOR) and high CO2 selectivity, we prepared a tandem Pt/Rh/SnOx, in which a Rh adlayer was deposited on a Pt substrate (Rh coverage: 0.28), followed by depositing several layers of SnOx only on the Rh surface (Sn coverage: 0.07). For reference, Sn was randomly deposited on the Rh-modified Pt (Pt/Rh) electrode whose Rh and Sn coverages were 0.22 and 0.36 (random Pt/Rh/SnOx). X-ray photoelectron spectroscopy demonstrated that Pt and Rh were metallic, and Sn was largely oxidized. Both Pt/Rh/SnOx electrodes were less positive in onset potential of EOR current density and higher in EOR current density than Pt and Rh/Pt electrodes. In situ infrared reflection-absorption spectroscopy demonstrated that the tandem Pt/Rh/SnOx electrode did not produce acetic acid, but produced CO2 in contrast to the random Pt/Rh/SnOx, suggesting that a tandem arrangement of Pt, Rh and SnOx, in which the Pt and SnOx sites were separated by the Rh sites, was effective for selective CO2 production. In the electrostatic electrolysis at 0.5 V vs. RHE, the tandem Pt/Rh/SnOx electrode exhibited higher EOR current density than the Pt and Pt/Rh electrodes after 1.5 h.
Recursive Cheating Strategies for the Relativistic FQ Bit Commitment Protocol
Authors: Bricout Rémi , Chailloux André
Published: August 2017

In this paper, we study relativistic bit commitment, which uses timing and location constraints to achieve information theoretic security. Using those constraints, we consider a relativistic bit commitment scheme introduced by Lunghi et al. This protocol was shown secure against classical adversaries as long as the number of rounds performed in the protocol is not too large. In this work, we study classical attacks on this scheme. We use the correspondence between this protocol and the CHSHQ game—which is a variant of the CHSH game—to derive cheating strategies for this protocol. Our attack matches the existing security bound for some range of parameters and shows that the scaling of the security in the number of rounds is essentially optimal.

Smart grid is an emerging technology which is considered to be an ultimate solution to meet the increasing power demand challenges. Modern communication technologies have enabled the successful implementation of smart grid (SG), which aims at provision of demand side management mechanisms (DSM), such as demand response (DR). In this paper, we propose a hybrid technique named as teacher learning genetic optimization (TLGO) by combining genetic algorithm (GA) with teacher learning based optimization (TLBO) algorithm for residential load scheduling, assuming that electric prices are announced on a day-ahead basis. User discomfort is one of the key aspects which must be addressed along with cost minimization. The major focus of this work is to minimize consumer electricity bill at minimum user discomfort. Load scheduling is formulated as an optimization problem and an optimal schedule is achieved by solving the minimization problem. We also investigated the effect of power-flexible appliances on consumers’ bill. Furthermore, a relationship among power consumption, cost and user discomfort is also demonstrated by feasible region. Simulation results validate that our proposed technique performs better in terms of cost reduction and user discomfort minimization, and is able to obtain the desired trade-off between consumer electricity bill and user discomfort.

Published: August 2017

With the increasing penetration of renewable energy in power systems, fluctuation of renewable energy power plants has great influence on stability of the system, and renewable power curtailment is also becoming more and more serious due to the insufficient consumptive ability of local power grid. In order to maximize the utilization of renewable energy, this paper focuses on the generation scheduling optimization for a wind-solar-thermal hybrid system considering that the produced energy will be transmitted over a long distance to satisfy the demands of the receiving end system through ultra-high voltage (UHV) transmission lines. Accordingly, a bilevel optimization based on a non-cooperative game method is proposed to maximize the profit of power plants in the hybrid system. Users in the receiving end system are at the lower level of the bilevel programming, and power plants in the transmitting end system are at the upper level. Competitive behavior among power plants is formulated as a non-cooperative game and the profit of power plant is scheduled by adjusting generation and bidding strategies in both day-ahead markets and intraday markets. In addition, generation cost, wheeling cost, and carbon emissions are all considered in the non-cooperative game model. Moreover, a distributed algorithm is presented to obtain the generalized Nash equilibrium solution, which realizes the optimization in terms of maximizing profit. Finally, several simulations are implemented and analyzed to verify the effectiveness of the proposed optimization method.
