Analysis of the Usefulness of a Serious Game to Raise Awareness about Mental Health Problems in a Sample of High School and University Students: Relationship with Familiarity and Time Spent Playing Video Games
Venue: Journal of clinical medicine
Year: 2019

One of the main challenges in the field of mental health today is the stigma towards individuals who have psychological disorders.  This study aims to analyse the usefulness of applying a serious game developed for the purpose of raising awareness among students about mental health problems and analyse whether its usefulness can be influenced by the type of video games or the time that students usually devote to playing with this type of entertainment.  The serious game introduces four characters who display the symptoms of different psychological disorders. A total of 530 students participated in the study, 412 of whom comprised the experimental group and 118 the control group, 291 came from secondary school classes and 239 were university students.  The findings show that this serious game significantly reduced total stigma among students. Variables like time habitually spent playing video games or video game preference had no bearing on the results.  Our findings suggest that the serious game is an appropriated tool to reduce stigma, both in high school and university students, independently of the type of video games that young people usually play, or time spent playing video games.
Increasing agricultural resilience through better risk management in Zambia
Year: 2018

A proper understanding of the risks faced by the agricultural sector and effective strategies to manage those risks is vital to creating a diversified and resilient economy for sustained growth and economic transformation. Increasing Agricultural Resilience through Better Risk Management in Zambia provides a rigorous analysis of the production, marketing, and enabling environment risks faced by Zambia's agricultural sector and prioritizes solutions to manage the risks. In terms of the severity and frequency of adverse impacts, the analysis shows that droughts, floods, price volatilities, and trade restrictions are the principal risks affecting agriculture in the country. Exposure to the consequences of these and other risks can be effectively limited through risk management systems tailored to the country's context. Three areas of risk management are found to warrant priority, with significant potential for synergizing actions undertaken across them: Strengthen early warning system to detect threats to food security; Develop climate smart agriculture and increase resilience to climate related shocks through diversification; and Develop the Zambian Commodity Exchange (ZAMACE) and build a shock responsive safety net.
Impact of Virtual Planning on Surgical Reposition of the Premaxilla Using an Endonasal Approach and Simultaneous Alveoloplasty
Venue: The Cleft palate craniofacial journal official publication of the American Cleft Palate Craniofacial Association
Year: 2019

Describe the surgical repositioning of the premaxilla using an innovative minimally invasive endonasal approach and secondary bone graft at the same time. We want to emphasize the importance of virtual surgical planning in this technique.  A total of 6 patients with bilateral complete cleft lip and palate underwent a surgical repositioning of the premaxilla. Virtual surgical planning was performed in all cases. The ages varied between 8 and 12 years and all were male. Five patients were in the mixed dentition phase and 1 patient was in the definitive phase. Three of the patients had been prepared with presurgical nasoalveolar molding. The other 3 were not prepared for various reasons. All patients had primary repair of cleft lip and palate.  An innovative minimally invasive endonasal approach is presented that has allowed a safe 3 D reposition of the premaxilla in patients with bilateral cleft palate. A simultaneous secondary alveoloplasty with the use of absorbable osteosynthesis is a good choice to achieve symmetry and stability.  Virtual surgical planning is an exceptional instrument to make an appropriate presurgical selection of the patients in which combine the 2 procedures.
Review on life cycle assessment of integrated solid waste management in some Asian countries
Year: 2013

The problems posed by municipal solid waste in Asia are more complex because here, most nations urbanize rapidly with about 30 50% population increase. In developing countries, the growth rate of most cities exceeds 4% per annum. The issue at stake is that the 20 40% of municipal revenues spent in most countries to manage the waste is not enough to handle the rising trend of the waste generated. The problems are multi dimensional. In Asia for example, issues ranging from disputes, norms, health concerns have continued to create obstacles and sometimes alarming situations. This had interfered with proper decisions in managing the waste that menaces the environment at a pace faster than the modern technology itself. In the paper some of the municipal solid waste management options are reviewed in some of these Asian countries with emphasis on a life cycle assessment (LCA) to adopt an integrated approach in solving the problem. Some solid waste management options were evaluated where some viable and suitable options could be derived based on Asian approach. Therefore, sustainable scenarios are suggested for stakeholders to manage municipal solid waste properly. The results are specifically intended to be used as a basis for decisions on strategies and policies for waste management and investments for new waste treatment facilities by decision makers in local, regional and national authorities or industries in the region.
Multiple adaptive strategies based particle swarm optimization algorithm
Venue: Swarm Evol. Comput.
Year: 2020

Although particle swarm optimization algorithm (PSO) has displayed promising performance on many optimization problems, how to balance contradictions between the exploration and the exploitation and rationally allocate computational resource are two crucial problems need to be dealt with in PSO study. In this paper, a PSO variant based on multiple adaptive strategies (MAPSO) is proposed. To efficiently maintain the population diversity, the entire population is split into multiple swarms, which can be regrouped during the evolutionary process. In each generation, different particles in a swarm adaptively select their learning exemplars (ALE) according to the performance of the particles. Thus, different particles in the same swarm can perform distinct search behaviors in each generation, as well as the same particle can conduct various search behaviors in different generations. In addition, aiming to rationally utilize computational resource, an adaptive strategy for population size (APS) is introduced. In APS, the population can adaptively delete unfavorable particles and add promising particles during the evolutionary process. Extensive experiments based on CEC2013 and CEC2017 test suites verify the superior performance of the multiple adaptive strategies on balancing the exploration and exploitation abilities. Furthermore, the performance of the newly introduced strategies is also testified by a set of experiments.
Project Holocene: The Clayful Phenomenology of Jomon Flame Pots
Venue: Cambridge Archaeological Journal
Year: 2021

As a ceramic artist, I was surprised to find that archaeological research gives little attention to the extraordinary sensorial qualities of Jomon flame pots. To understand why, I consider the challenges of including sensory experience in archaeological method and the problems of leaving it out. Turning to the typological approach to Jomon pottery, I highlight the assumptions it makes about cognition before introducing Material Engagement Theory (MET) as an alternative. A MET oriented reanalysis of the typological evidence places sensation at the centre of enquiry and removes the need to interpret symbolic, representational content. Through MET, I consider the sensorial qualities of flame pots, not as prehistory but as they appeared recently and unexpectantly during the process of modelling clay into sculptures for a contemporary art project. Flame pots joined conceptually with the explorative activity of clay. A prehistoric/contemporary artefact/modelling system was created and developed itself into a method of monitoring intra systemic experience clayful phenomenology. The findings cover five themes: enacted agency, iconicity from indexicality, bending rules/undermining habits, the choreography of material engagement and the phenomenology of space.
Designing a new infectious healthcare waste management system in sfax governorate, tunisia
Venue: 2014 International Conference on Advanced Logistics and Transport (ICALT)
Year: 2014

Infectious Healthcare Waste (IHW) management is of great importance due to its potential environmental hazards and public health risks. The collection and the disposal of IHW are highly visible and important services that involve large expenditures in the world and particularly in Tunisia. This paper discusses two main problems in the current solid IHW management practices in Sfax governorate (Tunisia) The first problem is about how choose the best waste treatment and disposal scenario, using a multiple criteria decision making analysis. The Analytic hierarchy process (AHP) implemented with Expert choice software, confirms that the best scenario is to apply central steam sterilization equipment, which will be used by all hospitals. Accordingly, the second problem concerns the off site transport of IHW from the twelve hospitals (public and private) in the governorate of Sfax to this overall center. This problem of transportation is modeled as a capacitated vehicle routing problem (CVRP) Experimental results are reported for the design of the routing system for IHW transportation, using the solver CPLEX 9.0 software. Future legislation concerning IHW management is supposed to take into account the various results of this research.
Key updatable public key encryption with keyword search (Or: How to realize PEKS with efficient key updates for IoT environments)
Venue: International Journal of Information Security
Year: 2019

Security and privacy are the key issues for the Internet of Things (IoT) systems. Especially, secure search is an important functionality for cooperation among users' devices and non trusted servers. Public key encryption with keyword search (PEKS) enables us to search encrypted data and is expected to be used between a cloud server and users' mobile devices or IoT devices. However, those mobile devices might be lost or stolen. For IoT devices, it might be difficult to store keys in a tamper proof manner due to prohibitive costs. In this paper, we deal with such a key exposure problem on PEKS and introduce the concept of PEKS with key updating functionality, which we call key updatable PEKS (KU PEKS) Specifically, we propose two models of KU PEKS: the key evolution model and the key insulation model In the key evolution model, a pair of public and secret keys can be updated if needed (e.g. the secret key is exposed) In the key insulation model, the public key remains fixed while the secret key can be updated if needed. The former model makes a construction simple and more efficient than the latter. On the other hand, the latter model is preferable for practical use since a user never updates their public key. We show constructions in each model in a black box manner. We also give implementation results on Raspberry Pi 3, which can be regarded as a reasonable platform of IoT devices.
Blockchain smart contracts: Applications, challenges, and future trends
Venue: Peer to Peer Netw. Appl.
Year: 2021

In recent years, the rapid development of blockchain technology and cryptocurrencies has influenced the financial industry by creating a new crypto economy. Then, next generation decentralized applications without involving a trusted third party have emerged thanks to the appearance of smart contracts, which are computer protocols designed to facilitate, verify, and enforce automatically the negotiation and agreement among multiple untrustworthy parties. Despite the bright side of smart contracts, several concerns continue to undermine their adoption, such as security threats, vulnerabilities, and legal issues. In this paper, we present a comprehensive survey of blockchain enabled smart contracts from both technical and usage points of view. To do so, we present a taxonomy of existing blockchain enabled smart contract solutions, categorize the included research papers, and discuss the existing smart contract based studies. Based on the findings from the survey, we identify a set of challenges and open issues that need to be addressed in future studies. Finally, we identify future trends.
Comparing Recurrence and Complications After Laparoscopy and Laparotomy Surgery among Patients Suffering from Colorectal Cancer, Shiraz, Iran.
Venue: Asian Pacific journal of cancer prevention APJCP
Year: 2016

The goal of this study was to compare the rate of recurrence and occurrence of complications in colorectal cancer patients after two kinds of laparoscopy and laparotomy.  A followup study was carried out among 358 patients who suffered from colorectal cancer from 20122014. The data were gathered from colorectal research center in Shiraz, Shahid Faghihi hospital, and analyzed using the chisquare test, logistic regression, and multinomial regression.  The average age of these patients was 56.3+ 14.6, 55.0% being men. Moreover, 57.8% of them underwent laparoscopy surgery and 42.2% of the patients underwent laparotomysurgery and the conversion rate was 58.0% which ultimately was put under the category of laparotomy surgery. After biennial median followup, differences in the occurrence of complications such as bleeding (hemorrhage) fever, intestine blockage and wound infection in these two kinds of surgery werestatistically significant (P<0.05) However, the rate of recurrence and the patients' ultimate status (alive without disease, alive with disease, and death) did not significantly differ between these two surgery groups.  Post operation complications were laparoscopy surgery were less than those in laparotomy. However, the outcomes such as patients' ultimate status and recurrence were similar between the two groups.

Black and Proud: The Story of an Iconic AFL Photo
Year: 2014

It is one of Australia's most iconic images. On 17 April 1993, the Indigenous AFL footballer Nicky Winmar stood up against racial abuse and made history. Facing the Collingwood crowd that had taunted him all day the St Kilda player pulled up his shirt, pointed to his chest and declared: 'I'm black and I'm proud to be black' Published the next day, the photos of Winmar's gesture sparked an intense debate that forced the AFL, the fans and the nation to confront their prejudices head on. Black and Proud takes us behind the searing image to the stories of those who made it happen the Indigenous team mates Nicky Winmar and Gilbert McAdam and the two photographers, Wayne Ludbey and John Feder. Bound by a love of the game, the four were brought together by acts of courage and vilification that show how far we have come and just how far we have to go. '17 April 1993 provided our most powerful image of Uncle Nicky and this book takes us to the stories behind it. These stories are courageous, inspiring, intimate and eye opening. This is a book all Australians need to read. Adam Goodes Winner of the Multicultural NSW Award at the 2015 NSW Premier's Literary Awards. Winner of the Australian Society for Sport History Book Award.
