Optimum Design Of Reinforced Concrete Foundations
Authors: Bedair Osama 
Published: January 2020

Background:
Optimization of reinforced concrete foundation is a challenging problem due to the
interaction between the design variables and design constraints. Classical design methods may overestimate
the size of the foundation, thus leading to excessive cost. By using current advances in computer technologies
and numerical optimization procedures, it is possible to find the optimum combinations of foundations design
parameters that minimize the cost.

Objectives:
The paper presents a numerical strategy to optimize the design of the reinforced concrete
foundation.

Methods:
The cost function is first derived in terms of the foundation design parameters. Mathematical
programming technique is utilized to minimize the cost function. Design constraints are used
against soil bearing capacity, concrete shear strength, flexural strength, and column bearing. Simplified
analytical models are developed to idealize the soil stress distribution. The numerical procedure
is then automated in a computer Program “OSFD” to perform sensitivity analysis and provide
guidelines that can be utilized in practice.

Results:
Design examples are provided to illustrate the efficiency of the optimization procedure.
Results are compared with existing common design procedures, commercial software and design
handbooks that are available in practice.

Conclusions:
The described procedure is very cost-effective and can be utilized by practicing engineers
in the industry to optimize the design of the reinforced concrete foundations.

Authors: Gan Jing , Fan Xiaobin , Song Zeng , Zhang Mingyue , Zhao Bin 
Published: January 2020

Background:
The power performance of an electric vehicle is the basic parameter. Traditional
test equipment, such as the expensive chassis dynamometer, not only increases the cost of testing
but also makes it impossible to measure all the performance parameters of an electric vehicle.

Objective:
A set of convenient, efficient and sensitive power measurement system for electric vehicles
is developed to obtain the real-time power changes of hub-motor vehicles under various operating conditions,
and the dynamic performance parameters of hub-motor vehicles are obtained through the system.

Methods:
Firstly, a set of on-board power test system is developed by using virtual instrument (Lab-
VIEW). This test system can obtain the power changes of hub-motor vehicles under various operating
conditions in real-time and save data in real-time. Then, the driving resistance of hub-motor vehicles is
analyzed, and the power performance of hub-motor vehicles is studied in depth. The power testing system
is proposed to test the input power of both ends of the driving motor, and the chassis dynamometer
is combined to test so that the output efficiency of the driving motor can be easily obtained without
disassembly. Finally, this method is used to carry out the road test and obtain the vehicle dynamic performance
parameters.

Results:
The real-time current, voltage and power, maximum power, acceleration time and maximum
speed of the vehicle can be obtained accurately by using the power test system in the real road experiment.

Conclusion:
The maximum power required by the two motors reaches about 9KW, and it takes
about 20 seconds to reach the maximum speed. The total power required to maintain the maximum
speed is about 7.8kw, and the maximum speed is 62km/h. In this article, various patents have been discussed.

The Schools of Government perform a central role to the public service of many countries. Despite being a disseminated and well-established phenomenon, the functions and even the concept of Schools of Government vary. Aiming to portray the functions and characteristics of Schools of Government around the world and offer a better understanding of them, this paper presents a comparative study of Schools of Government located across five continents. Based on purposive sampling, eight Schools of Government were selected to be part of this in depth study: École Nationale d'Administration, ENA – France; Canada School of Public Service, CSPS – Canada; Instituto Nacional de la Administración Pública, INAP – Argentina; Australia and New Zealand School of Government, ANZSOG – Australia and New Zealand; Civil Service College, CSC – Singapore; National School of Government, NSG – South Africa; Direcção Geral da Qualificação dos Trabalhadores em Funções Públicas, INA – Portugal; and Escuela Superior de Administración Pública, ESAP – Colombia. Data collection procedures included interviews and document analysis. Data was analyzed using content and comparative analysis. This study highlights some important dimensions of Schools of Government including the position within the government, funding, main activities, organizational structure and personnel. Other similarities (e.g. among members of Commonwealth) and possible common trends and innovation challenges are also discussed. Finally, we discuss the results comparing them to previous studies findings.

Visualizing an Ethics Framework: A Method to Create Interactive Knowledge Visualizations From Health Policy Documents
Authors: Sleigh Joanna , Schneider Manuel , Amann Julia , Vayena Effy 
Published: January 2020

Background
Data have become an essential factor in driving health research and are key to the development of personalized and precision medicine. Primary and secondary use of personal data holds significant potential for research; however, it also introduces a new set of challenges around consent processes, privacy, and data sharing. Research institutions have issued ethical guidelines to address challenges and ensure responsible data processing and data sharing. However, ethical guidelines directed at researchers and medical professionals are often complex; require readers who are familiar with specific terminology; and can be hard to understand for people without sufficient background knowledge in legislation, research, and data processing practices.

Objective
This study aimed to visually represent an ethics framework to make its content more accessible to its stakeholders. More generally, we wanted to explore the potential of visualizing policy documents to combat and prevent research misconduct by improving the capacity of actors in health research to handle data responsibly.

Methods
We used a mixed methods approach based on knowledge visualization with 3 sequential steps: qualitative content analysis (open and axial coding, among others); visualizing the knowledge structure, which resulted from the previous step; and adding interactive functionality to access information using rapid prototyping.

Results
Through our iterative methodology, we developed a tool that allows users to explore an ethics framework for data sharing through an interactive visualization. Our results represent an approach that can make policy documents easier to understand and, therefore, more applicable in practice.

Conclusions
Meaningful communication and understanding each other remain a challenge in various areas of health care and medicine. We contribute to advancing communication practices through the introduction of knowledge visualization to bioethics to offer a novel way to tackle this relevant issue.

BackgroundLesbian, gay, bisexual, transgender, and queer (LGBTQ) community centers remain important venues for reaching and providing crucial health and social services to LGBTQ individuals in the United States. These organizations commonly use Facebook to reach their target audiences, but little is known about factors associated with user engagement with their social media presence.ObjectiveThis study aimed to identify factors associated with engagement with Facebook content generated by LGBTQ community centers in the United States.MethodsContent generated by LGBTQ community centers in 2017 was downloaded using Facebook’s application programming interface. Posts were classified by their content and sentiment. Correlates of user engagement were identified using negative binomial regression.ResultsA total of 32,014 posts from 175 community centers were collected. Posts with photos (incidence rate ratio, [IRR] 1.07; 95% CI 1.06-1.09) and videos (IRR 1.54; 95% CI 1.52-1.56) that contained a direct invitation for engagement (IRR 1.03; 95% CI 1.02-1.04), that expressed a positive sentiment (IRR 1.11; 95% CI 1.10-1.12), and that contained content related to stigma (IRR 1.16; 95% CI 1.14-1.17), mental health (IRR 1.33; 95% CI 1.31-1.35), and politics (IRR 1.28; 95% CI 1.27-1.29) received higher levels of engagement.ConclusionsThe results of this study provide support for the use of Facebook to extend the reach of LGBTQ community centers and highlight multiple factors that can be leveraged to optimize engagement.
Why Employees (Still) Click on Phishing Links: An Investigation in Hospitals
Authors: Jalali Mohammad S , Bruckes Maike , Westmattelmann Daniel , Schewe Gerhard 
Published: January 2020

Background
Hospitals have been one of the major targets for phishing attacks. Despite efforts to improve information security compliance, hospitals still significantly suffer from such attacks, impacting the quality of care and the safety of patients.

Objective
This study aimed to investigate why hospital employees decide to click on phishing emails by analyzing actual clicking data.

Methods
We first gauged the factors that influence clicking behavior using the theory of planned behavior (TPB) and integrating trust theories. We then conducted a survey in hospitals and used structural equation modeling to investigate the components of compliance intention. We matched employees’ survey results with their actual clicking data from phishing campaigns.

Results
Our analysis (N=397) reveals that TPB factors (attitude, subjective norms, and perceived behavioral control), as well as collective felt trust and trust in information security technology, are positively related to compliance intention. However, compliance intention is not significantly related to compliance behavior. Only the level of employees’ workload is positively associated with the likelihood of employees clicking on a phishing link.

Conclusions
This is one of the few studies in information security and decision making that observed compliance behavior by analyzing clicking data rather than using self-reported data. We show that, in the context of phishing emails, intention and compliance might not be as strongly linked as previously assumed; hence, hospitals must remain vigilant with vulnerabilities that cannot be easily managed. Importantly, given the significant association between workload and noncompliance behavior (ie, clicking on phishing links), hospitals should better manage employees’ workload to increase information security. Our findings can help health care organizations augment employees’ compliance with their cybersecurity policies and reduce the likelihood of clicking on phishing links.

Authors: Suku Yohanes Laka , Je Kristoforus 
Published: January 2020

Holes are often made inside the column structure for plumbing, mechanical, and electrical installation purposes may affect the structural performance of the column. Therefore, this paper aims to model and analyze the effect of holes in reinforced concrete column structures due to lateral loads. Data were obtained from the reference frame structure of the previous researcher, with varying centric column holes of 0%, 2%, 4%, 6%, 8%, 10%, and 12%, respectively to the column cross-sectional area. Furthermore, a hole with a ratio of 4% to the column cross-sectional area was placed at 5 and 10 mm eccentric to the center of column cross-section to examine the influence of holes position in the perforated column. The frame structure was modelled and analyzed by Finite Element (FE) using ABAQUS software. The result showed that the maximum load, displacement, and crack pattern resulted from the model is close to the experimental result. The results of the analysis showed that with the hole size of 2% to 12% of the column cross-sectional area, the frame strength was reduced by 5.43% to 15.56%. The frame strength was also reduced by 2.77% and 6.14% when the hole placed 5mm and 10 mm eccentric to the center of the column cross-section area. The displacement of the frame also decreases by 59.63% to 74.60% when the holes with the ratio of 2% to 12% to the column cross-sectional area exist in the column. The existence of eccentric holes on the column reduced the performance of the frame structure, by decreasing its strength, displacement and ductility.

Authors: Hardita Ardhianing , Ismiyati Titik , Wahyuningtyas Endang 
Published: January 2020

Denture base material should have a good level of biocompatibility. Acrylic resin is frequently used as a denture base material, however it has a disadvantage of producing residual monomer. Residual monomer is known to have a cytotoxicity effect. Titanium dioxide (TiO2) nanoparticles are used as fillers due to their biocompatibility and ability to enhance the mechanical properties of acrylic resin. The addition of the material to acrylic resin could affect the amount of residual monomer. The aim of this study was to examine the effect of the addition of TiO2 nanoparticles as acrylic resin denture base filler on the cytotoxicity in fibroblast cells. The samples consisted of 24 heat cured acrylic resins in disc shape (5 mm in diameter and 2 mm in thickness), divided into 4 groups (n = 6): three groups given treatment with0.5%, 1%, 2% TiO2, respectively and one control group. Cell viability was measured with MTT assay. The results were tested with one way ANOVA with 95% confidence level followed by LSD post hoc test. The results showed that the highest percentage of cell viability was found in the treatment group of 0.5% TiO2 with value of 91.83 ± 1.75%, while the lowest value was seen in the treatment group of 2% TiO2 with value of 79.38 ± 3.34%. Significant differences were shown between the treatment groups of 0.5% and 2% TiO2, as well as between the control and treatment group with 2% TiO2. The conclusions of this research are the addition of TiO2 nanoparticles as acrylic resin denture base filler has an effect on cytotoxicity; the addition of 0.5% TiO2 nanoparticles filler results in lower cytotoxicity on fibroblast cells compared to the addition of 1% and 2% TiO2.

Published: January 2020

This study tries to article tries to discuss and mapping the dialectical models between text and reality in the daily human life. 'Limitations' of the text and the development of the time,requires Qur’an to be able to dialogue with the context of space and time. So that,the message of the Qur’an can be understood by human beings, in various dimensions of space and time. One of the Qur'anic communication models with the times is throughthe dialectical model. With the content analysis method, based on the Mushaf Utsmani as its reference, the results show, that there are at least Eleven dialectical models offered by the Qur'an, namely: Alsibr wa Altaqsim (breaking and showingthe opponents' opinions), Istifham Taqriri (questions that have one answer to the truth), Qiyas Mudhmar (Enthimeme), Qiyas Khalaf (Syllogism per Impossible), Qiyas Tamtsil (Reasoning by Analogy), Istidlal by using stories, Altaslim (Presupposition), Almunaqadhah (Refutation), Dalik Alikhtira' and Dalil Alhuduts (the argument which shows everything has its creator), and the continued Dalil. One of the philosophical functions that can be applied with these various dialectical models areto strengthen the argument for the truth of life in the hereafter.
