Published: September 2020

Agriculture is one of the key sectors of Vietnam economy as well as most country in the world. Nowadays, the urgent requirement for it is an increase in production, quality of labor and labor productivity. Therefore, we researched and built self-propelled robot serving in agriculture. This promises to be one of the pioneer products with application of science and technology to modernize agriculture in our country. The robot is based on combining two main components: Automatic guided vehicle (AGV) and Delta robot with different specific tasks. Being an AGV, robot can locate and automatically move in the field without human intervention. Besides, the Delta robot is the main structure impacting directly on the field such as: watering, weeding, fertilizing, … depending on our need.This paper focuses on analyzing 3 major sections: the overall design of robot, control algorithms and computer vision programs. The System Overview helps readers have an overview of the shape and operation of robot. The control algorithm focuses on control algorithm analysis of Delta robot. And the last part introduces the computer vision programs used in Robot.The experimental results are evaluated objectively, so we can see both of the successes and the limitations. But in general, with the task set out in the subject: identifying and following vegetable rows in combination with identifying and moving the robot arm to the target need to be impacted, the robot has done very well and the results are within acceptable errors.
A Genetic Algorithm Application in Planning Path Using B-Spline Model for Autonomous Underwater Vehicle (AUV)
Authors: Tran Ngoc Huy , Nguyen Anh Duy , Nguyen Thanh Nam
Published: September 2020

This paper proposes a method of using the B-spline mathematical model to plan high smoothness curve trajectories with heading condition through given waypoints for autonomous underwater vehicles (AUVs) in particular and ships with rudder systems in general. In addition, this paper examines some of the physical limitations of this vehicle, which lead to some binding conditions of the trajectory. Besides, the paper applies B-spline approximation method to reduce the curvature of the trajectory, when waypoints are too close and we do not need to go through exactly these waypoints in the 2D plane. Finally, this paper also proposes the genetic algorithm application with some modifications to solve the optimization of B-spline path length with constraint in turning radius of the vehicle.

Reopening the academic library in the post-pandemic season: A lesson-learned from the COVID-19 pandemic
Authors: Fernando I. D. K. L. , Jayasekara P. K.
Published: September 2020

Information has becoming the most valuable asset in the emerging world. Hence, information has become one of the major driving forces that lead a country towards sustainable development. While the libraries and other information centers are closed around the world, it could be adversely affected on the economy and general livelihood of the society. Thus, continuing the information services uninterruptedly is a matter of significance. However, the continuum of library services during lock-down situations and post-pandemic scenarios should be practice with proper care and understanding, especially during the post-pandemic conditions when re-commencing work in an academic library after the lock-down situation. Prevailing COVID -19 pandemic has provided an eye-opening lesson for academic librarians to re-think the way they perform and in what ways they can prepare for the post-pandemic reopening of the library. With the knowledge of the COVID -19 pandemic and related pathological nature of the virus, the present approach attempts to formulate an input while reopening the academic libraries of Sri Lanka. The concept also is applicable while planning to provide library services in similar post-lockdown scenarios. Practical safety precautions were suggested after conducting a thorough literature search in relevant and reputed journal databases, magazines and official websites. It can be recommended that the library should formulate a dedicated body, with the leadership of one senior member of the library staff for the overall monitoring and assessment of the pandemic-safety in the reopening time. Awareness of the libraries' stakeholders via different mediums, develop policies for disinfection, meetings, and other official tasks can be suggested. Following a country-specific existing-strategy that developed for the libraries of Sri Lanka is highly recommended. As a summary, the academic library should formulate an integrated pandemic prevention protocol to serve the library patrons with a delightful post-pandemic reopening experience.
Correlation between the Altmetrics Attention Score (AAS) and the Citation Count (CC): A study based on highly cited breast cancer articles
Authors: Jayasekara P. K. , Abu K. S.
Published: September 2020

Measuring the impact of a research publication is a vital factor in the scholarly world. Citation count is a single dimension of measuring the impact of a scholarly publication. However, the evolution of the Internet has changed the ways of accessing research publications and research communication. As result of the Internet, altmetric became a popular tool to measure the research impact. The objective of the article is to identify the correlations between Citation Count and Altmetrics Attention Score based on the top 100 highly cited articles available in the Web of Science database. The scholarly publications related to breast cancer published in 2014 were selected as the target population. Web of Science database was used to collect the bibliographic information and citation count of the highly cited articles. The keyword “Breast Cancer” was used in the ‘title’ field of WoS and the search was limited to open access journal articles. The search results were arranged according to the times cited from highest to lowest and ranked according to the citation count. The articles within the top 100 rankings according to the citation count were selected as the sample of this study. Altmetrics bookmarklet was used to collect the Altmetrics Attention Scores of the selected articles. Data were analyzed using SPSS 20 software and Microsoft Excel. Spearman’s rank order correlation coefficient was used to determine the relationship between Citation Count and Altmetrics Attention Score. The study revealed that there is a positive correlation (rs = .552, p < 0.01) between the Citation Count and the Altmetrics Attention Score.

Published: September 2020

Chronic coronary syndrome (CCS) is a newly proposed entity by the European Society of Cardiology that replaces stable coronary artery disease (CAD), which is defined as a progressive process of plaque accumulation in coronary circulation with associated functional changes. CCS has replaced stable CAD to raise awareness that despite the clinically silent nature of the disease, there are progressive pathological changes occurring in the coronary arteries. This has allowed clinicians to review the current various diagnostic modalities, methods of risk stratifying patients based on different models and the various management options available, including lifestyle modifications, pharmacological therapies, and revascularization. With the emergence of this new entity, great emphasis has been placed on the consolidation of our comprehension of the dynamic character of the disease and the preventative actions that aim to reduce the cardiovascular disease burden.

Abstract>

Aim: The study aimed to compare the in vitro antibacterial activity of an ethanol extract of Rosmarinus officinalis “romero” (EERO) at different concentrations with Streptococcus mutans ATCC 25175. Materials and Methods: We worked with three concentrations of 25%, 50%, and 75% of the EERO and compared these with the positive control chlorhexidine 0.12% and distilled water as a negative control. Seeding was performed in Müller–Hinton agar medium. The inhibitory effectiveness of EERO was determined using the disc diffusion method with the experimental solutions. The seeded and inoculated plates were incubated at 37°C, for 24 and 48 h. The reading was carried out according to the Kirby–Bauer method by measuring the diameter (mm) of the inhibition halo formed by the bacteria using a Vernier caliper and recorded on a data collection sheet. Results: In the 24-h group, chlorhexidine 0.12% showed the highest inhibition halos with a mean of 12.8 ± 0.8 mm, followed by EERO 75% with a similar mean of 12.1 ± 0.6 mm. Similarly, at 48 h, chlorhexidine 0.12% had the highest antibacterial activity of 13.0 ± 0.7 mm followed by EERO 75% with 12.2 ± 0.5 mm. Conclusions: The EERO showed inhibitory effectiveness against S. mutans, with the concentration of 75 mg/ml showing similar results, albeit not statistically significantly different, to those of chlorhexidine.

Published: September 2020

Aim: This study is aimed to evaluate the effect of exogenous matrix metalloproteinases (MMPs) inhibitors on immediate shear bond strength (SBS) of resin composite attached to primary teeth dentin. Methods: Sixty extracted anterior primary teeth were selected. A dentin block (6.0 mm × 6.0 mm × 2.0 mm) was obtained from each tooth. All dentin blocks (n = 60) were pretreated for 60 s with either 0.01 M phosphate-buffered saline (pH 7.2) in the control group (Group I), chlorhexidine (CHX) 2% (Group II), doxycycline (DOX) solution 2% (Group III), and ethylenediaminetetraacetic acid (EDTA) 17% (Group IV) before applying etch-and-rinse adhesive system (Adper Single Bond 2). After adhesive application, composite resin (Filtek 3M, USA) was applied, and then, SBS values were determined with a universal testing machine. Results: There were no significant differences between SBS values of DOX, EDTA, and the control group (P < 0.05). SBS values reduced when CHX was applied, although the reduction was not statistically significant (P = 0.961). The DOX group showed the highest bond strength values (8.82 ± 3.29), which was significantly greater than the CHX (P = 0.026). Conclusion: Based on the results, pretreatment with MMPs inhibitors was not advantageous with regard to improving the immediate SBS of composite attached to primary teeth dentin.

Published: September 2020

Cortical transit time (CTT) has recently been shown to be a useful parameter in the management of children with pelviureteric junction obstruction (PUJO). The aim of this study was to assess intraobserver and interobserver variations in the qualitative and quantitative assessment of CTT in children with PUJO. A retrospective study was performed, and 99mTc-MAG3 renogram images of all children with PUJO performed from January 2016 to December 2017 were retrieved. The images were assessed by three observers at two different time points. CTT was qualified as delayed if CTT was more than 3 min else; it was noted as normal. The intraobserver and interobserver variations in the results of the CTT of the normal kidney and affected kidney both before and after surgery were studied. The kappa statistic was used to compare the interobserver variation of qualitative interpretation of CTT. The Bland–Altman plot was used to evaluate the intraobserver and interobserver variations of the quantitative interpretation of CTT. A total of 57 99mTc-MAG3 renal scintigraphies were evaluated. Overall, 114 renal units were evaluated with 51 normal renal units and 63 renal units with PUJO. Of these, 63 renal units with PUJO, 31 renal units had been operated upon, whereas the remaining 32 renal units had no intervention at the time of the study. The kappa statistic in the normal, affected operated, and affected unoperated kidneys was interpreted as almost perfect, substantial to almost perfect, and moderate to substantial level of agreement, respectively. The Bland–Altman plot revealed a large mean difference and wide 95% limits of agreement in affected kidneys (both operated and unoperated). The study concludes that the qualitative CTT interpretation in the affected renal unit which is most commonly used in recent studies is a reliable and reproducible parameter in children with PUJO. The quantitative measurement had wide inter- and intraobserver variation for clinical use.

Published: September 2020

18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (CT) is an important tool widely used in the oncology to stage and restage various malignancies. Intense focal FDG uptake in the lung parenchyma associated with the absence of anatomical lesion detected on CT can be explained by a lung microembolism, known as hot-clot artifact. We report, to the best of our knowledge, the first case describing a single hot-clot artifact located in the same lung as a histologically proven non-small cell lung cancer.

Published: September 2020

Acacia mangium Willd est une espèce à croissance rapide, fixatrice d’azote, capable de restituer au sol des éléments minéraux par chute de litière. Elle est actuellement très utilisée dans les programmes de reboisement. L’effet substrat sur la biomasse des plants, à l’âge de plantation, a été estimé dans le but d’optimiser les conditions de production des plants. Un dispositif en blocs complets randomisés comprenant six types de substrats à base de terre noire, charbon et sciure de bois, a été mis en place. Des jeunes plants âgés de trois semaines ont été transplantés dans des plaques alvéolées comprenant différents substrats puis élevés jusqu’à l’âge de plantation. Une dose de 30 g d’engrais NPK dilués dans 10 l d’eau a été apportée quotidiennement aux plants. Les résultats obtenus montrent un effet substrat sur la biomasse et la croissance. Les plants issus des substrats 6 (75% terre+25% charbon) et 4 (50% terre+50% charbon) présentent les meilleures performances de croissance. L’Activité Réductrice d’Acétylène (ARA) réalisée a été influencée par le substrat. La dose de fertilisation apportée n’a pas engendré l’avortement des nodules. Le substrat 5 (50% de terre noire, 25% de charbon et 25% de sciure de bois) offre les conditions optimales de développement des nodules.Mots clés : Substrat, Acacia mangium, biomasse, ARA.

Published: September 2020

Marine space is constantly threatened by various sources of pollution that may reduce its economic potential and have negative repercussions on human health. This study aims to assess heavy metals contamination of eight fish species and their impact on human health. Heavy metals such as cadmium, lead, copper and zinc were determined by atomic absorption spectrophotometry in fresh, cooked and fried fish. The results found in fresh fish (cadmium: 0.002 to 0.005 mg / kg, lead: 0 to 0.031 mg / kg, copper: 0.0045 to 0.305 mg / kg, zinc: 0.1245 to 0.6195 mg / kg), in cooked fish (cadmium: 0.0035 to 0.005 mg / kg, lead: 0 to 0.01 mg / kg, copper: 0 to 0.021 mg / kg, zinc: 0.171 to 0.327 mg / kg) and in fried fish (cadmium: 0.004 mg / kg, lead: 0 to 0.007 mg / kg, copper: 0 to 0.016 mg / kg, zinc: 0.0875 to 0.5065 mg / kg) showed that heavy metal levels are all below the standard values accepted by FAO / WHO. The consumption of these fish could therefore have no negative effect on the population’s health. Both types of cooking have both positive and negative effects on the heavy metal reduction in fish species. Although the concentrations of heavy metals are not worrying, the vigilance of the populations and a variation of the diet are important to guarantee a better health.Keywords: Heavy metals, health impact, Atlantic see fish, Cotonou.

L’aulacodiculture est une option privilégiée à la fourniture de protéines animales. Cette étude a été menée dans le but de déterminer l’effet d’un aliment granulé sur les caractéristiques organoleptiques et biochimiques de leur viande. Ainsi, un lot d’aulacodes a été nourri au granulé tandis que l’autre nourri au fourrage avec complément alimentaire (aliment classique). Après un abattage normal, les membres antérieurs et postérieurs des animaux ont été prélevés. La viande des membres postérieurs a été retenue pour l’analyse organoleptique (couleur, texture, jutosité, flaveur, tendreté) par 12 panelistes en trois répétitions. La viande des membres antérieurs a servi à la détermination de la matière sèche, des protéines brutes, de la matière grasse et des cendres brutes. Ces travaux montrent que la viande d’aulacode est juteuse, tendre avec une texture grossière et une flaveur prononcée quel que soit le type d’aliment. Le profil sensoriel montre une différence tant au niveau de la couleur qu’au niveau de la jutosité et de la texture. Quant aux paramètres biochimiques, aucune différence significative n’a été observée (p ≥ 0,05). Il convient de retenir que la viande d’aulacodes nourris au granulé a été plus appréciée tant pour la couleur, la texture, la jutosité que pour la flaveur.

This study aimed at determining the effect of a granulated food on the organoleptic and biochemical qualities of grasscutter meat. Thus, three grasscutters were randomly selected from a batch of animals fed with a granulated food and the other three from the batch fed with the conventional food. After normal slaughter, the fore and hind limbs were removed. The meat of the posterior limbs was selected for organoleptic analysis by a panel of 12 consumers in three repetitions. The meat from upper limbs was used to evaluate the biochemical parameters such as dry matter, crude protein, fat and raw ash. Results showed that the meat of the grasscutter was juicy, tender with a coarse texture and a pronounced flavor whatever the type of food. The sensory profile showed a significant difference in color, juiciness, and texture of meat. With respect to biochemical parameters, no significant difference was observed (p ≥ 0.05). The type of food had no effect on biochemical parameters of grasscutter meat. However, the organoleptic parameters influenced significantly the level of appreciation of grasscutter meat.

The drivers of creativity and innovation in copyright discourse: a value chain analysis across cultural industries
Authors: Yu Ke , Darch Colin
Published: September 2020

We build on the well-established critique, primarily in the US literature, of the following assumptions: (1) copyright protections serve to incentivise creativity; (2) copyright is designed with such incentivisation as its primary purpose; and (3) a standardized set of copyright protections should ideally be applicable to all forms of cultural production, across all situations in all countries. These assumptions lead to two fundamental conceptual flaws in much current copyright policy discourse: (1) it conflates concepts such as incentive, reward, and recognition; (2) it is nomothetic in character insofar as the existing structural and procedural diversity of the different cultural industries that it governs is inadequately acknowledged. Our critique in this article is not, therefore, a general one, but is limited to a specific theory of copyright, which pretends that copyright is an incentive to creativity while the evidence indicates that it is not. We highlight the importance of taking account of the whole ‘creativity value chain’ in the different industries with their various components – the creator, the copyright holder, the distributor, and the market. Drawing on case studies of three creative industries: literary writing, film, and fashion, we demonstrate that not only is there currently considerable heterogeneity among these industries, but that there has also been heterogeneity within each industry at different periods and in different contexts. We argue that this flexibility is a beneficial characteristic of the current functioning of copyright that should be defended against pressures in favour of harmonization.
The public interest and patent injunctions: Evalve v Edwards Lifescience [2020] EWHC 513 (Pat)
Authors: Johnson Phillip
Published: September 2020

It is usual for a court to grant a final injunction after a finding of patent infringement. But there has been some uncertainty about how this applied when the patent covered essential medical products. In Evalve v Edwards Lifescience [2020] EWHC 513 (Pat), the court explored the role of the public interest in withholding injunctions and awarding damages in lieu. It construed the public interest narrowly in part due to the existence of compulsory licences. This discussion explores the court's reasoning and suggests that an even stronger link with compulsory licences should be adopted.

A abordagem está fundamentada na visão de geógrafos que realizaram expedições antárticas como membros do Núcleo de Pesquisas Terrantar/UFV. Abordou-se sobre algumas possibilidades de regionalização da Antártica. Apesar de ser um território internacional destinado a paz e ciência, existem disputas geopolíticas. Os estudos sobre Geomorfologia possibilitam o monitoramento da dinâmica dos glaciares e que se faça reconstruções paleoambientais. Informações sobre os solos são importantes para registros de contaminações ambientais, monitoramento do permafrost, e auxílio na interpretação das paisagens exuberantes e cheias de mistérios. Análises climáticas nas sensíveis paisagens Antárticas são relevantes para melhor compreensão das mudanças climáticas. Massas de ar e correntes marítimas oriundas do continente influenciam nos regimes térmicos e precipitações na América do Sul. Estes conteúdos tem grande potencialidade de utilização no ensino de Geografia, podendo tornar as aulas mais atrativas e estimulantes.

Background: Past studies have analyzed the health risks associated with alfalfa sprout production and developed standard procedures to reduce foodborne illnesses. There have been no studies related to microgreen outbreaks, specifically wheatgrass. Wheatgrass has become a growing culinary trend and the potential health risks associated need to be evaluated. Alfalfa sprouts and wheatgrass both share the same initial growth production – pre-soak and germination. The only difference is the harvesting period. This paper evaluated the risks associated with alfalfa sprout production and compared it with wheatgrass production by contaminating both alfalfa sprouts and wheatgrass with E. coli The presences of E. coli in the plant’s juices were evaluated and compared. Method: Alfalfa sprouts and wheatgrass were grown in similar conditions, in hydroponic condition, with an additional wheatgrass in soil. The plants were grown and harvested according to its respective pre-soaking and harvesting period, as specified by the Canadian Food Inspection Agency. The plants were inoculated with Escherichia coli during the germination period, and then juiced to examine the presences of E. coli within its internal structure. The Hygiena systemSURE II luminometer was used to detect the presences of E. coli via the MicroSnap™ Enrichment and E. coli detection swabs. Results: The result showed that E. coli was present in both wheatgrass and alfalfa sprouts juice. The root systems of the food products were independent of each other. The types of growth medium used for wheatgrass were also independent of each other. Conclusion: The study found that growing microgreens should be treated similarly to sprout productions. Food facilities with wheatgrass production need to be aware of safe handling, production, and storage of wheatgrass to prevent foodborne illnesses.

Objective: Personal service establishments (PSEs) include tattoo parlors, piercing shops, and beauty salons. Many of the services provided have potential to spread diseases due to the invasive nature and possibility of cross contamination if sanitation procedures are not followed. Potential infections such as nontuberculosis mycobacterium, staphylococcus aureus and blood borne infections such as Hepatitis and HIV are possible. There is concern among Environmental Health Officers (EHOs), and professionals in the industry regarding the lack of regulations and training of employees within the industry. This study investigated the criteria and safety measures the public takes when determining which personal service establishment they receive treatments from. Methods: A questionnaire was administered online through social media and Google Docs. Inferential statistical analyses determined if there were associations between certain demographic information and the responses given from participants. Results: There were six associations that were found when comparing demographic groups (age, gender and education) with the survey questions. A p value of 0.021008 was found in the association between age and perceived level of regulation of the industry, a p value of 0.014407 was found in the association between education and asking about sanitation procedures before an appointment, and a p value of 0.008668 was found in the association of education and if participant asks for references. In addition, p values of 0.028151 and 0.011739 with associations of gender and education, respectively, and the participants perceived ability to recognize bad practices during a procedure. Finally, a p value of 0.029766 was found in the association of gender and participants interest in additional information about how to choose an establishment. Conclusions: There were six hypotheses that resulted in statistically significant associations between a demographic and the survey question. Over 30 year olds chose PSEs were minimally regulated, while higher education groups were more likely to ask about sanitation and for references before a procedure. Females and people with some post secondary education felt they were more able to recognize bad practices during a procedure. Finally, females were most interested in additional information about PSEs.
Contrasting the effectiveness of chloramines reduction in indoor swimming pools disinfected by ozone versus UV
Authors: Chan Iris , BCIT School of Health Sciences, Environmental Health  , Sidhu Bobby
Published: September 2020

Objectives: Chloramines are disinfection by-products that are produced between chlorine and contaminants in the pool. Exposures to chloramines at high levels or for extended durations have been found to cause mucous membrane irritations and respiratory distress in humans. To reduce chloramines production, secondary treatment in the form of UV and ozone are used in newer indoor swimming pools. This study aimed to examine whether there is a difference between UV and ozone treatment in their effectiveness in reducing chloramines in indoor pools. Killarney leisure pool and whirlpool, which utilized ozone treatment, as well as Hillcrest leisure pool and whirlpool, which utilized UV treatment, were studied. Methods: Hach Pocket Colorimeter 2 Analysis System which used a DPD method of analysis was used to determine concentrations of free chlorine and total chlorines. Concentrations of chloramines were calculated by subtracting the concentration of free chlorine from total chlorine. Thirty pool water samples for each type of pool system were analyzed on random days in the afternoons of January and February, 2015. A two sample t-test was used to compare the chloramines concentrations of the whirlpools; while a Mann-Whitney U test was used to compare the chloramines concentrations of the leisure pools. Results: There was a statistically significant difference between the mean chloramines concentration of the UV-treated whirlpool and that of the ozone-treated whirlpool (p = 0.00854). However, there was not a statistically significant difference between the mean chloramines concentration between the UV treated leisure pool and that of the ozone treated leisure pool (p = 0.882048). Conclusions: It was determined that UV was more effective than ozone in reducing chloramines concentrations in indoor public whirlpools. Therefore, in order to choose a treatment that leads to the greatest reduction of health hazard posed to pool patrons, UV is preferred. Whirlpools that intend to adopt secondary treatment may consider UV.
Effectiveness of mechanically tenderized beef labels on influencing practices of cooking beef in British Columbia
Authors: Heran Arunjit , BCIT School of Health Sciences, Environmental Health  , Sidhu Bobby
Published: September 2020

Background: Mechanically tenderized beef poses a higher risk for Escherichia coli 0157:H7 infection than intact beef and has been implicated in several outbreaks. As such, all products are mandated to be labeled in Canada. Purpose: This study assessed the effectiveness of mechanically tenderized beef labels on influencing practices of cooking beef in British Columbia. Methods: 74 adults within British Columbia who cooked beef were surveyed electronically using a snowball method. An inferential (Pearson chi-square analysis) and descriptive analysis was performed on the nominal data in PSPP and Microsoft Excel respectively. Results: Only 8% of respondents abided with information on mechanically tenderized beef labels. No statistically significant associations were found between practices of abiding with information on mechanically tenderized beef labels and various socio-demographic factors (e.g. age, gender, education level, and food safety education) (p<0.01). The practice of not using food thermometers was the major contributing factor that lowered the effectiveness of mechanically tenderized beef labels. Conclusion: Mechanically tenderized beef labels were ineffective in influencing behaviours of cooking beef in British Columbia. Therefore, other risk communication strategies are needed to persuade adults in British Columbia to adequately cook mechanically tenderized beef products. Recommendations: Future studies can assess whether the general public is properly cooling mechanically tenderized beef as the label does not address this practice.

Published: September 2020

Background: Knowledge translation (KT) is the process of using the best available knowledge to inform decision-making. Public Health Inspectors (PHIs) are tasked with the critical responsibility of protecting public health. However, there is little data available about how effective and consistent current methods of distributing information to professionals across Canada are. The efficacy of KT has implications on the PHI profession and ultimately, public health protection. Objective: The purpose of this research is to identify how PHIs across Canada take evidence and incorporate it into practice. Methods: A survey was created with questions focused on determining what information PHIs use when making public health decisions, how PHIs go about finding the information required, and the level of trust invested into each source of data. Questions were formulated with guidance from the National Collaborating Centre of Environmental Health (NCCEH). It was distributed electronically to PHIs via social media and BCIT. Results: PHIs use evidence-based information to advise their decisions and actions always (43%) or often (46%) in daily practice. Government agencies, professional organizations, peer-reviewed literature, and colleagues are most often used and deemed as reliable resources. Although very frequently used, the internet was seen as neither reliable nor unreliable. 77% of respondents cited that barriers exist that impede their access to evidence-based information. The most common barriers listed were time constraints, costs, and lack of relevant information. Conclusions: The internet is becoming an increasingly popular means by which knowledge is delivered. However, web-based public health resources need to be more concise, easily accessible, PHI-specific and facilitated by reliable entities to effectively address barriers to practice. Increased communication of evidence, practices, and standards are required between health authorities, government agencies, and PHI professionals to ensure consistent and cohesive protection of public health.

Published: September 2020

Background and Purpose: The 2011 Fukushima Daiichi nuclear reactor incident in Japan resulted in the release of large quantities of radioactive material into the Pacific Ocean through deposition from the atmosphere and liquid discharges from the nuclear facility. Public misconceptions and the scarcity of radiation monitoring along the west coast of Canada have create doubt within the population regarding the safety of the ocean. A radiation survey along some of Vancouver’s beaches was completed to determine whether radioactivity from Fukushima has reached our local shores. Methods: Radiation surveys were conducted at three different locations; Sunset, Spanish Banks and Jericho Beach in Vancouver, British Columbia. Gamma radiation levels were measured using both the Radeye, GR 135 Plus EXPLORANIUM survey meters. At each beach, 30 samples of water, sand and various different artifacts including algae, stones and logs were each surveying. If the radiation detected exceed 0.05μSv/Hr the identification function of the GR 135 Plus EXPLORANIUM would be used to determine if it was from natural or artificial sources. The radiation levels were compared to the expected normal background levels (between 0.05μSv/Hr- 1.0 μSv/Hr) as well as to observed if there was any sufficient differences between the mediums under investigation. Results: The radiation levels along all three beaches did not exceed normal background levels (between 0.05μSv/Hr- 1.0 μSv/Hr). Furthermore, characteristic radionuclides released from this incident, specifically Cesium 134 and Cesium 134, were not detected. There was no sufficient difference between the radiation levels observed from the sand, water and different artifacts (logs, stones, and algae) Conclusion: It was concluded that the radiation levels along the beaches, Jericho, Spanish Banks and Sunset Beach do not present an additional risk to the public visiting this area as a result of this incident.
