Published: September 2019

Abstract
Background Back pain is one of the most important public health problems. It is on rise among adolescent and pupils’ population. The aim of this study was to assess the relationship between cognitive factors (skills, knowledge, self-efficacy, and expectation beliefs) and back care behavior among pupils.Methods A cross sectional study was conducted on a random sample of students attending public elementary schools in Tehran, Iran from October 2018 to March 2019. They completed a questionnaire containing items on cognitive abilities and a checklist to assess their skills on back care behaviors. Stepwise multiple regression analysis was performed to find out the contribution of cognitive factors on outcome.Results In all, 204 students were entered into the study. The results revealed that 95.3% of the variance in the back behavior was explained by self-efficacy (β=0.586, t=12.08, P<0.001), expectation beliefs (β=0.232, t= 5.08, P<0.001), and skills (β=0.181, t=4.46, P<0.001).Conclusion These results showed that the pupils who had more confident, skills, and expectation beliefs were more likely to do proper back behavior. In this regard, school-based back pain prevention interventions should be addressed using key cognitive factors that consider the potential change strategies.

Abstract
Continuing medical education (CME) as part of life-long learning in medicine should focus on patient outcomes and appropriate care by increasing knowledge, competence and/or performance of clinicians. In this article, we present the views of the different stakeholders on the future of CME, presented at the ISSECAM colloquium held in December 2018. Within the framework of the colloquium, a survey was done asking health care professionals about their learning practices. We present an integrated summary of the attendees’ views and survey results. Key elements for effective learning in CME and how they can be implemented have been identified. Increased interactivity and focus on real-life practice seem to have the highest likelihood to induce behavioural changes. In addition, online CME activities will steadily gain more weight in the learning curriculum of medical practitioners. CME providers should take these elements (interactivity, real-life practice, online) into consideration when designing their different activities.

Abstract
Background: To design and evaluate a mobile app to provide Mobile Clinical Education (MCE).Students: 181 students from the Nursing Department of Nanjing Medical University. Methods: The students were divided into an MCE group and a control group based on their class organization. “Nutrition” was chosen as the experimental course. The MCE app was developed and applied during a whole semester for the MCE group, while the control group was taught using the traditional method of passive transfer of information from lecturer to group of students. Results: The MCE group performed better on the final examination (69.1 ± 7.5 vs 67.9 ± 6.7, t = 1.127, P = 0.26); and in terms of general evaluation(74.9 ± 6.0 vs 67.9 ± 6.7, t = 7.419, P < 0.001). There was a significant increase in the MCE group after introduction of MCE in terms of course appeal (t = -4.75, P < 0.001), classroom communication and the opportunity to discuss and debate what they had learnt (t = -4.5, P < 0.001) and course content (t = -4.44, P < 0.001).Conclusion: MCE has been found to improve learning and the overall experience. The application and promotion of this teaching method should improve medical education in terms of flexibility, practicability and extensiveness.

Designing a Midterm Reading Test for Junior High School Students in Semarang: A Practical Experience of a Master Student in TESOL
Authors: Waliyadin Waliyadin 
Published: September 2019

Designing a test is an uneasy task. It is proven by the fact that many teachers find difficulties in designing a good test. The present article attempts to review the English school exam in Indonesia and present an example of the test design of a midterm reading test for junior high school students in Semarang. To this end, firstly, a sample of test script of the school exam for JHS students in Semarang in the academic year 2017/2018 was reviewed. The review of the test shows that creating a good quality of test items still become a concern for English teachers as they made some grammatical errors. Consecutively, a midterm reading test was also designed and administered in a junior high school in Semarang, Central Java. Then, the test designed was evaluated by considering the validity, reliability, and practicality as suggested by (Brown Abeywickrama, 2010). The administration of the test and evaluation show some weaknesses; therefore, the suggestions for the betterment of the test design are also made, such as revising some test items with a very low facility index and negative discrimination index. This study implicates pedagogically the teachers to train students on how to summarize and paraphrase since these skills underrepresented.

Abstract
Presence of cyanotoxins in drinking water poses a great risk to public health. Elevated levels of cyanotoxins in drinking water can lead to acute gastroenteritis, liver diseases, and neurotoxicity. In this study, drinking water samples were collected across the eastern part of Qatar and screened using a rapid assay to detect the presence of microcystins and nodularins. The results showed that the toxin concentrations in all the water samples were below the WHO prescribed limit of 1 μg/L. Considering a worst-case scenario, toxin removal efficiencies were evaluated using ozone and ozone-hydrogen peroxide by spiking drinking water samples with microcystin-LR (MC-LR) at different oxidant dosages, toxin concentrations, water temperatures, and total organic carbon. It was found that peroxone-treated water samples have better MC-LR removal efficiency than molecular ozone at lower oxidant dosages. Nevertheless, at higher oxidant dosages, both ozonation and peroxone oxidation methods showed a similar removal efficiency. The experimental results also clearly indicated that variation in water temperature between 22 °C and 35 °C has minimal effect on the removal efficiency in both the treatment methods. It was also confirmed that the presence of organic carbon has a more profound detrimental impact than water temperature for toxin removal.
Prediction of side thermal buoyant discharge in the cross flow using multi-objective evolutionary polynomial regression (EPR-MOGA)
Authors: Khosravi Milad , Javan Mitra 
Published: September 2019

Abstract
The capability to predict the distribution of pollutants in water bodies is one of the most important issues in the design of jet outfalls. Three-dimensional computational fluid dynamics (CFD) model and multi-objective evolutionary polynomial regression (EPR-MOGA) are used and compared in modeling the temperature field in the side thermal buoyant discharge in the cross flow. The input variables used for training the EPR-MOGA models are spatial coordinates (x, y, z), jet to cross flow velocity ratio (R), depth of the channel (d), and the temperature excess (T0). A previous experimental study is used to verify and compare the performance of the EPR-MOGA and CFD models. The results show that the EPR-MOGA model predicts the thermal cross section of the flow and the spread of pollutants at the surface with a better accuracy than the CFD model. However, the CFD method performs significantly better than EPR-MOGA in predicting temperature profiles. The uncertainty analysis indicated that the EPR-MOGA model had lower mean prediction error and smaller uncertainty band than the CFD model. The relationships achieved by the EPR-MOGA model are very useful to predict temperature profiles, temperature half-thickness, and temperature spread on surface in practice.
An improved friction calculation for water level and flow velocity simulation

Published: September 2019

Abstract
Flow friction is the key to studying water movement and has been one of the most important research topics in hydraulics and river dynamics. The roughness coefficient in the Manning formula represents friction applied to the flow by channel and changes with the river section characteristics, water level, and flow velocity. However, the Manning formula tends to simulate the friction with little variability, which contributes to large errors in the simulation of water level and flow velocity. To solve this problem, we proposed an improved friction formula based on the relationships between roughness coefficient and energy gradient and developed a differential model of one-dimensional flow with the proposed friction formula. The developed model was tested against both the experimental flood data and observed flow data in Qiantang River, China. The results indicated that the proposed friction formula provides a better simulation of target friction than the original Manning friction formula. The parameters in the proposed friction formula are less sensitive to the river section characteristics. Our results also showed that the developed differential model using the proposed friction formula can simulate the water level and flow velocity well in both the calibration and validation period and can improve the simulation of water level in tidal reach.
Advances in the Prediction of Protein Aggregation Propensity
Authors: Pallarés Irantzu , Ventura Salvador 
Published: September 2019

Background:
Protein aggregation into β-sheet-enriched insoluble assemblies is being
found to be associated with an increasing number of debilitating human pathologies, such as Alzheimer’s
disease or type 2 diabetes, but also with premature aging. Furthermore, protein aggregation
represents a major bottleneck in the production and marketing of proteinbased therapeutics.
Thus, the development of methods to accurately forecast the aggregation propensity of a certain
protein is of much value.

Methods/Results:
A myriad of in vitro and in vivo aggregation studies have shown that the aggregation
propensity of a certain polypeptide sequence is highly dependent on its intrinsic properties
and, in most cases, driven by specific short regions of high aggregation propensity. These observations
have fostered the development of a first generation of algorithms aimed to predict protein
aggregation propensities from the protein sequence. A second generation of programs able to map
protein aggregation on protein structures is emerging. Herein, we review the most representative
online accessible predictive tools, emphasizing their main distinctive features and the range of
applications.

Conclusion:
In this review, we describe representative biocomputational approaches to evaluate
the aggregation properties of protein sequences and structures, while illustrating how they can
become very useful tools to target protein aggregation in biomedicine and biotechnology.

Socioeconomic and Demographic Statuses as Determinants of Adherence to Antiretroviral Treatment in HIV Infected Patients: A Systematic Review of the Literature
Authors: Azmach Nuredin Nassir , Hamza Temam Abrar , Husen Awel Abdella 
Published: September 2019

Background:
Socioeconomic and demographic statuses are associated with adherence to
the treatment of patients with several chronic diseases. However, there is a controversy regarding
their impact on adherence among HIV/AIDS patients. Thus, we performed a systematic review of
the evidence regarding the association of socioeconomic and demographic statuses with adherence
to antiretroviral therapy (ART) among HIV/AIDS patients.

Methods:
The PubMed database was used to search and identify studies concerning about socioeconomic
and demographic statuses and HIV/AIDS patients. Data were collected on the association
between adherence to ART and varies determinants factors of socioeconomic (income, education,
and employment/occupation) and socio-demographic (sex and age).

Findings:
From 393 potentially-relevant articles initially identified, 35 original studies were reviewed
in detail, which contained data that were helpful in evaluating the association between socioeconomic/
demographic statuses and adherence to ART among HIV patients. Two original research
study has specifically focused on the possible association between socioeconomic status and
adherence to ART. Income, level of education, and employment/occupational status were significantly
and positively associated with the level of adherence in 7 studies (36.8%), 7 studies (28.0%),
and 4 studies (23.5%) respectively out of 19, 25, and 17 studies reviewed. Sex (being male), and age
(per year increasing) were significantly and positively associated with the level of adherence in 5
studies (14.3%), and 9 studies (25.7%) respectively out of 35 studies reviewed. However, the determinant
of socioeconomic and demographic statuses was not found to be significantly associated
with adherence in studies related to income 9(47.4%), education 17(68.0%), employment/
occupational 10(58.8%), sex 27(77.1%), and age 25(71.4%).

Conclusion:
The majority of the reviewed studies reported that there is no association between socio-
demographic and economic variables and adherence to therapy. Whereas, some studies show
that age of HIV patients (per year increasing) and sex (being male) were positively associated with
adherence to ART. Among socio-economic factors, the available evidence does not provide conclusive
support for the existence of a clear association with adherence to ART among HIV patients.
There seems to be a positive trend between socioeconomic factors and adherence to ART in some of
the reviewed studies.
Gangue Entrainment in Olivine Flotation: Effect of MIBC Dosage on the Mitigation of Lizardite Recovery
Authors: Guler Taki , Polat Ercan 
Published: September 2019

Background:
Olivine is an important industrial raw material especially for metallurgical
applications like foundry sand, refractory, slag conditioning, etc. Loss On Ignition
(LOI) value (>1%) is the main specification of olivine ore/concentrate for those areas
together with the chemical specifications.

Objective:
This flotation study was conducted in natural pH condition with Na-oleate as
collector to clarify the effect of frother (MIBC) dosage on the LOI value of olivine concentrate.

Methods:
Characterization of ore sample for this study was made by XRD, XRF and petrographic
analyses. Lizardite, a serpentine group mineral, was found to be a hydrated soft
fraction of ore sample in addition to hard olivine and pyroxene minerals constituting ore.

Results:
Finely ground soft lizardite adversely affected the olivine flotation in a way of entraining
mechanically into concentrate. LOI value of concentrate was observed mainly to
be froth volume depended issue, and therefore, mainly water recovery dependent. LOI value
increased proportionally with water recovery at longer flotation time and MIBC dosages
indicating the entrainment of lizardite as the suspending hydrophilic component of water
phase. Certain rate of the hydrated lizardite mineral was thought to be recovered via hydrophobization,
which was clearly seen especially at the initial stages of flotation period in
the presence of excess frother. This experimental finding was attributed to similar chemical
composition of minerals constituting ore, and accidental activation of lizardite.

Conclusions:
Lizardite recovery in froth was explained with accidental activation and/or
weak attachment of locked particles onto froth bubble although main recovery mechanism
was determined to be mechanical entrainment. Olivine concentrate obeying the specifications
of metallurgical applications could be obtained at suitable MIBC dosage and flotation
time.
Another Consequence of SFAS 123R: Equity Compensation to Retirement Eligible CEOs
Authors: Balsam Steven , Song Ki Kyung 
Published: September 2019

ABSTRACT
SFAS 123R, which mandates expensing the fair value of equity compensation over its vesting period, requires companies expense the entire fair value on the grant date when a retirement eligible employee is allowed to retain that compensation even if s/he retires prior to the end of that vesting period. From the firms' point of view, SFAS 123R makes equity compensation less attractive for executives approaching retirement. Consistent with this hypothesis, our results show that relative to younger executives, equity compensation decreases for executives approaching retirement post-SFAS 123R. We find evidence consistent with this decrease varying with the negotiating power of the employee, i.e., when we decompose our sample into CEO versus non-CEO named executive officer we only find a decrease for non-CEOs. We also find evidence consistent with firms differentially responding to this requirement, i.e., we find that new economy firms are less likely to reduce equity compensation.
