RESUMEN

The circular economy (CE) is reasoned to organize complex systems supporting sustainable resilience by distinguishing between waste materials and economic growth. This is crucial to the electronic waste (e-waste) industry of developed countries, and e-waste operation management has become their top priority because e-waste contains toxic materials and valuable sources of elements. In the UK, although London Metropolitan city boasts an ambitious sustainable resilience target underlying the context of CE, practical implementation has yet to be feasible, with few investigations detailing if and how the existing target implications enable industrial and social-ecological sectors to continue their performance functionalities in the face of undesired disruptions. In this paper, a dynamic Bayesian Network (dynamic BN) approach is developed to address a range of potential risks. The existing London e-waste operation management is considered as an application of study for sustainable resilience development. Through the utilization of dynamic BN, a comprehensive analysis yields a Resilience Index (RI) of 0.5424, coupled with a StdDev of 0.01350. These metrics offer a profound insight into the intricate workings of a sustainable system and its capacity to swiftly rebound from unexpected shocks and disturbances. This newfound understanding equips policymakers with the knowledge needed to navigate the complexities of sustainable e-waste management effectively. The implications drawn from these in-depth analyses furnish policymakers with invaluable information, enabling them to make judicious decisions that advance the cause of sustainable e-waste management. The findings underscore that the absorptive capacity of a sustainable and resilient e-waste operation management system stands as the foremost defense mechanism against unforeseen challenges. Furthermore, it becomes evident that two pivotal factors, namely "diversifying the supply chain" and "enhancing supply chain transparency," play pivotal roles in augmenting the sustainability and resilience of e-waste operation management within the context of London's ambitious sustainability targets. These factors are instrumental in steering the trajectory of e-waste management towards a more sustainable and resilient future, aligning with London's aspirations for a greener and more eco-conscious future.

RESUMEN

Currently used pesticides (CUPs) were introduced to have lower persistence and bioaccumulation, and lesser bioavailability towards non-target species. Nevertheless, CUPs still represent a concern for both human health and the environment. India is an important agricultural country experiencing a conversion from the use of obsolete organochlorine pesticides to a newer generation of phytosanitary products. As for other developing countries, very little is known about the transfer of CUPs to the human diet in India, where systematic monitoring is not in place. In this study, we analyzed ninety four CUPs and detected thirty CUPs in several food products belonging to five types: cereals and pulses, vegetables, fruits, animal-based foods, and water. Samples were taken from markets in Delhi (aggregating food produced all over India) and in the periurban area of Dehradun (northern India) (representing food produced locally and through more traditional practices). Overall, chlorpyrifos and chlorpropham were the most detected CUPs with a detection frequency of 33% and 25%, respectively. Except for vegetables and fruits, the levels of CUPs in all other food types were significantly higher in samples from Delhi (p < 0.05). Exposure dosage of CUPs through different food matrices was calculated, and chlorpropham detected in potatoes had the maximum exposure dosage to humans (2.46 × 10-6 mg/kg/day). Risk analysis based on the hazard quotient technique indicated that chlorpyrifos in rice (2.76 × 10-2) can be a concern.

RESUMEN

To measure the amount of noise produced in busy parts of a metropolitan and also to assess the audiological status of the civilians exposed to such noise. Cross-sectional study for one year between June 2017 and May 2018 was conducted. Noise was measured in four busy parts of an urban city with a digital sound level meter. People involved in various occupations in the busy parts for more than one year within the age range of 15-45 years were included. Maximum noise level recorded was 106.4 dBA in Koyembedu. Average noise was around 70-85 dBA in Chennai. Totally 100 people were subjected to audiological assessment (69 Males; 31 Females). Among them 93% had hearing loss. Hearing loss was almost equal both in sexes. Sensory hearing loss was the major type (83%). All areas were almost equally affected with maximum (100%) being affected in Annanagar and Koyembedu. The right ear was more affected than the left. All age groups were affected among which the working age group (36-45) years was most affected. The unskilled occupation group was most affected (100%). There was a positive relation between noise levels and hearing loss. Duration of exposure did not have positive correlation with hearing loss. Noise pollution and its induced hearing loss was more prevalent and increased in all four areas. As hearing loss due to noise pollution is predominant as observed in the study, awareness about noise pollution and its effects among the community is a necessity.

RESUMEN

In the era of global urbanization, the cities across the world are experiencing significant change in the climate pattern. However, analysing the trend and pattern of rainfall over the urban areas has a number of challenges such as availability of long-term data as well as the uneven distribution of rain-gauge stations. In this research, the rainfall regionalization approach has been applied along with the advanced statistical techniques for analysing the trend and pattern of rainfall in the Delhi metropolitan city. Fuzzy C-means and K-means clustering techniques have been applied for the identification of homogeneous rainfall regions while innovative trend analysis (ITA) along with the family of Mann-Kendall (MK) tests has been applied for the trend analysis of rainfall. The result shows that in all rain-gauge stations of Delhi, an increasing trend in rainfall has been recorded during 1991-2018. But the rate of increase was low as the trend slope of ITA and Sen's slope in MK tests are low, which varies between 0.03 and 0.05 and 0.01 and 0.16, respectively. Furthermore, none of the rain-gauge stations have experienced a monotonic trend in rainfall as the null hypothesis has not been rejected (p value > 0.05) for any stations. Furthermore, the study shows that ITA has a better performance than the family of MK tests. The findings of this study may be utilized for the urban flood mitigation and solving other issues related to water resources in Delhi and other cities.

RESUMEN

Confirmed cases of coronavirus in Africa, particularly in Ethiopia, are increasing rapidly following improved testing. This study is aimed at assessing the perceptions and practices towards coronavirus among the metropolitan city population of Amhara region, Ethiopia, and examining the associated factors affecting public perceptions and practices regarding coronavirus among the population of metropolitan cities. A total of 1288 randomly selected participants completed a questionnaire designed to assess perceptions and practices towards coronavirus and associated factors. The statistical analysis involved fitting a binary logistic regression model and a chi-square test. Of 1288 study participants, 788 (61.2%) and 500 (38.8%) were male and female, respectively. Their average age and monthly income were 29.2 years and 2484 birr, respectively. Preventive measures followed by the participants involved washing hands with soap and water rubbing for at least 20 s (55.4%) and visiting a doctor when corona symptoms show up (49.5%). Permanent rural residents had lower odds of good perception and practices regarding coronavirus (aOR=0.505; 95% CI=0.15, 0.82) as compared to permanent urban resident participants. Due to misguided perceptions and practices, the prevalence of coronavirus in metropolitan city communities of Amhara region is high. The city of residence, marital status, educational level, permanent residence, and information sources were significantly associated with people's perceptions and practices towards the prevention of coronavirus. Perceptions and practices towards coronavirus had a significant positive correlation in terms of preventive measures against coronavirus. Therefore, the authors would like to recommend if substantive effort from the government and different stakeholders regarding to raising the perception and practices of communities in the cities towards the pandemic and reduce the collateral damage especially the lower income communities who cannot afford basic needs.

RESUMEN

BACKGROUND: Emerging and reemerging pathogens are global challenges for public health and the pandemic of Coronavirus disease 2019is a reemerging case of an infectious disease caused by Severe Acute Respiratory Syndrome-Corornavirus-2. Health care worker worldwide are at higher risk worldwide and the situation is the same in Nepal. The knowledge and attitude of health workers will certainly mark the outcome towards this pandemic. So, this study aims to assess the knowledge and attitude of community health workers towards the prevention of COVID-19 virus. METHODS: A descriptive cross-sectional study was carried out among the community health workers of various provinces of Nepal. A semi-structured, self-administered questionnaire was prepared in Google form and circulated to the sampled health workers through various social media platforms like face book, messenger, Instagram and g-mails. A total of 650 invitations were send and among them 420 responded and among them only 399 provided complete response. Responses containing anonymized data was collected analyzed in using SPSS-version-20. The results were interpreted and was checked with various demographic and enabling factors using chi-square test and logistic regression model. Also, ethical approval was taken from NHRC (Nepal Health Research Council (protocol registration number: 360/2020P) prior to the conduction of study. RESULTS: Out the total sample size of 450, we took 399 responses taking into consideration all the inclusion criteria. So, from 399 valid response, 230 (47.6%) were males and 169 (42.4%) were females. 380 (95.2%) employed participants thought that wearing PPE will reduce the chances of getting COVID-19, majority of the participants 80.5% (321) responded that COVID-19 will successfully be controlled and staffs receiving excellent support from palika had high knowledge level. Knowledge level was significantly associated with the enabling factor "support from palika" (P = 0.045).45.9% of the respondents had no availability of COVID-19 response medical items for prevention of COVID-19 at their respective health facilities. Also the logistic regression analysis revealed that the odds of knowledge level was 2 times higher (AOR=1.913 at 95% CI: 1.266-2.891) compared to the female participants (Ref- female). CONCLUSIONS: Proper and adequate knowledge and attitude towards COVID-19 is a paramount in the prevention and control of SARS-COV-2. Health care workers are knowledgeable about COVID-19 and are proactively practicing the preventive measures to minimize the spread of infection but some lack optimistic attitude. Hence, the constantly updated educational programs related to COVID-19 will surely contribute to improving the healthcare workers knowledge and attitude towards COVID-19.

RESUMEN

Many areas around the world are affected by Groundwater Level rising (GWLr). One of the most severe consequences of this phenomenon is Groundwater Flooding (GF), with serious impacts for the human and natural environment. In Europe, GF has recently received specific attention with Directive 2007/60/EC, which requires Member States to map GF hazard and propose measures for risk mitigation. In this paper a methodology has been developed for Groundwater Flooding Susceptibility (GFS) assessment, using for the first time Spatial Distribution Models. These Machine Learning techniques connect occurrence data to predisposing factors (PFs) to estimate their distributions. The implemented methodology employs aquifer type, depth of piezometric level, thickness and hydraulic conductivity of unsaturated zone, drainage density and land-use as PFs, and a GF observations inventory as occurrences. The algorithms adopted to perform the analysis are Generalized Boosting Model, Artificial Neural Network and Maximum Entropy. Ensemble Models are carried out to reduce the uncertainty associated with each algorithm and increase its reliability. GFS is mapped by choosing the ensemble model with the best predictivity performance and dividing occurrence probability values into five classes, from very low to very high susceptibility, using Natural Breaks classification. The methodology has been tested and statistically validated in an area of 14,3 km2 located in the Metropolitan City of Naples (Italy), affected by GWLr since 1990 and GF in buildings and agricultural soils since 2007. The results of modeling show that about 93% of the inventoried points fall in the high and very high GFS classes, and piezometric level depth, thickness of unsaturated zone and drainage density are the most influencing PFs, in accordance with field observations and the triggering mechanism of GF. The outcomes provide a first step in the assessment of GF hazard and a decision support tool to local authorities for GF risk management.

RESUMEN

Plastics are widely considered to be a major threat particularly in the urban areas owing to extensive use of plastic products. The current study is the first investigation to highlight the microplastics (MPs) pollution from the freshwater (Ravi River) located in the predominant urban center, i.e., Lahore, Pakistan. The concentration profile was quantified from surface water (n = 19) and sediments (n = 19) collected from different drains and canals of predominant freshwater resources in Lahore, Pakistan. The highest content of MPs was observed in the sullage carrier with mean concentration of 16,150 ± 80 MPs/m3 and 40,536 ± 202 MPs/m2 in the water and sediments respectively. The lowest level was detected in the link canals with mean concentration of 190 ± 141 MPs/m3 in the water and 683 ± 479 MPs/m2 in the sediments. The proportion of large size MPs (300 µm-5 mm) was maximum in the upstream section of Ravi river, whereas fine size MPs (50-150 µm) were dominant in the downstream section. In terms of shapes, the fragments were predominant with a relative abundance of 56.1% and 83.1% followed by fibers with a relative abundance of 38.6% and 11.8% in the water and sediments respectively. The chemical composition analysis showed that most of the fibers, fragments, and beads were polyethylene while the sheets were composed of polypropylene. Nevertheless, the foams isolated from the samples were composed of polystyrene. Within 24 h, about 2.4 ± 2.4 billion microplastic pieces were estimated to be transported from a single water channel into the river. The highest discharge of MPs was estimated from the sullage carrier with about 7 billion pieces/day.

RESUMEN

Arsenic exposure route for humans is through the drinking of contaminated water and intake of arsenic-contaminated foods, particularly in arsenic-exposed areas of Bengal delta. Transport of the arsenic-contaminated crops and vegetables grown using arsenic-contaminated groundwater and soil in arsenic-exposed areas to the uncontaminated sites and consequent dietary intakes leads to great threats for the population residing in non-endemic areas with respect to consumption of arsenic through drinking water. We have studied the food materials collected from 30 families and their dietary habits, apparently who consume arsenic-free drinking water as well as 9 well-known markets of Kolkata city. The total and inorganic arsenic intake has been estimated from the collected foodstuffs from the market basket survey (n = 93) and household survey (n = 139), respectively for human risk analysis. About 100% of the collected samples contained detectable amount of arsenic (range 24-324 µg/kg), since the origin of the food materials was somewhere from arsenic-endemic areas. The daily consumption of inorganic arsenic (iAs) from rice grain and vegetables for adult and children is 76 µg and 41.4 µg, respectively. Inorganic arsenic (mainly arsenite and arsenate) contributes approximately 88% of the total content of arsenic in vegetable. In most of the cases, insufficient nutrient intake by the studied population may lead to arsenic toxicity in the long run. An independent cancer risk assessment study on the same population indicates that the main risk of cancer might appear through the intake of arsenic-contaminated rice grain and cereals.

RESUMEN

Water services providers should supply water that is fit for human consumption, taking into account multi-barrier approaches and technical aspects such as design aspects, operation monitoring, final water quality compliance monitoring, plant monitoring practices, maintenance, and risk management practices. Against this background, this study focused on applying the diagnostic tool for technical compliance as well as assessing the compliance of water treatment plants with management norms. Six plants in the Vhembe District Municipality were selected; the Vondo, Malamulele, Mutshedzi, and Mutale plants (conventional), and the Dzingahe and Tshedza package plants. During the first assessment, four (Malamulele, Mutshedzi, Mutale and Dzingahe) plants scored between 44% and 49% and achieved Class 3 certification, revealing serious challenges requiring immediate intervention. Two water plants (Vondo and Tshedza, scoring 53% and 63%, respectively) were in the Class 2 category, revealing serious challenges requiring attention and improvement. During the second assessment, all plants scored between 63% and 87% (Class 2 category). The greatest improvement (30%) was noted for the Dzingahe and Tshedza plants, followed by the Malamulele plant, while the Mutale, Vondo, and Mutshedzi plants improved their scores by 20%, 17% and 14%, respectively. After corrective actions and re-measurement, no plant complied. It is recommended that Water Services Providers (WSPs) regularly apply the diagnostic tools and water safety plans as developed in order to comply with applicable standards.

RESUMEN

To determine whether rapid HIV tests in public health centers might encourage voluntary HIV testing, a pilot project was conducted in four selected public health centers in Seoul, 2014. During the period April 10 to November 28 of pilot project, 3,356 rapid tests were performed, and 38 were confirmed as positive. The monthly average numbers of voluntary HIV tests and HIV-positive cases were up to nine-fold and six-fold larger, respectively, than those of the period before application of the rapid HIV test. Among 2,051 examinees that completed questionnaires, 90.3% were satisfied. In conclusion, the use of rapid HIV tests in public health centers promoted voluntary HIV testing and was satisfactory for examinees.

RESUMEN

We explored factors influencing presentation with advanced human immunodeficiency virus (HIV) disease by age group. Data were derived from a city-wide cross-sectional survey of 759 HIV-infected adults living in Seoul, Korea. The significance of each observed factor was assessed via multivariate logistic regression. Of subjects aged 20-34 years, lower educational level had a positive influence on presentation with advanced HIV disease (adjusted odds ratio [aOR], 2.43; 95% confidence interval [CI], 1.36-4.34); those recently diagnosed with HIV were more likely to be presented with advanced HIV disease (aOR, 3.17; 95% CI, 0.99-10.2). Of the subjects aged 35-49 years, those w ith advanced HIV disease were more likely to have been diagnosed during health check-ups (aOR, 2.91; 95% CI, 1.15-7.32) or via clinical manifestations (aOR, 3.61; 95% CI, 1.39-9.36). Of the subjects aged ≥ 50 years, presentation with advanced HIV disease was significantly more common in older subjects (aOR per increment of 5 years, 2.06; 95% CI, 1.32-3.23) and less common among individuals diagnosed with HIV in 2000-2006 (aOR, 0.18; 95% CI, 0.04-0.83). In conclusion, a lower educational level in younger subjects and more advanced age in older subjects positively influence the presentation of advanced HIV disease.

RESUMEN

Many studies have investigated risk factors for suicidal ideation and suicide attempt; however, most have failed to show differences in risk factors between suicidal ideation and suicide attempt among the human immunodeficiency virus (HIV)-infected population. This study was designed to identify differences in risk factors between suicidal ideation and suicide attempts among HIV-infected adults in Seoul. A face-to-face survey of 457 HIV-infected adults was conducted by the Seoul Metropolitan Government in 2013. Multivariate logistic regression analysis was used to identify factors associated with suicidal ideation and suicide attempt. Among 422 participants, 44% had suicidal ideation, and 11% had suicide attempts. The independent risk factors for suicidal ideation were young and middle age, living with someone, history of AIDS-defining opportunistic disease, history of treatment for depression, lower social support, and psychological status. Beneficiaries of National Medical Aid, economic barriers to treatment, history of treatment for depression, and lower psychological status were independently associated with suicide attempts. Patients with HIV in Korea were treated without cost in some centers. Thus, experiencing an economic barrier to treatment might be due in part to ignorance of HIV care policies. Our findings indicate that suicide attempts are associated with socioeconomic factors and information inequality regarding medical care. In conclusion, suicidal ideation closely associated with the psychosocial factors, whereas suicide attempt demonstrates a stronger association with socioeconomic factors. Suicide prevention measures should be implemented to provide information to help HIV-infected patients.

RESUMEN

In order to study the characteristics of norovirus in Gwangju metropolitan city, We examined norovirus in 13,931 fecal specimens collected through five years (2008-2012) from children admitted with a chief complain of acute diarrhea. Among a total of norovirus (NoV) was most frequently detected (3,025 cases, 21.7%). Concerning the frequency of virus detected by month, NoV tended to break out frequently from October to March in the following year. NoV was detected most highly in 0~3 year infants. Through examinations on NoV genotypes, among 3,025 cases that turned out to be positive, the genotypes of 2,652 cases were determined with various results including 13 types of GI and 17 types of GII. The results of analysis on GI genotypes were as follows: GI-4 (21.9%), GI-2 (15.2%), and GI-6 (10.5%). GII genotypes were as follows: GII-4 (63.9%), GII-3 (18.9%), GII-8 (4.2%), GII-2 (3.9%), GII-6 (3.3%), and GII-1 (1.9%). Eight types of variants for GII-4 genotype (427 cases) were identified. The majority of the GII-4 variants was GII-4_Farmington (181 cases, 42.4%), which peaked in 2012, while GII-4_2008b (173 cases, 40.5%) showed a high prevalence in 2011. Concerning the circulation of variants, as many as eight types of GII-4 variants were identified in 2012, showing more varieties than in other years. Therefore, this study can be used as fundamental data for the development of vaccine candidate for the prevention of viral diarrheal diseases with high-incidence.

RESUMEN

Group A rotaviruses are a major cause of acute gastroenteritis in young children worldwide. For the proper management of rotavirus infections, knowledge of the distribution of G and P genotypes including detection of emerging genotype is crucial. Therefore, the aim of this study is to describe epidemiological changes in rotavirus gastroenteritis in Gwangju metropolitan city, South Korea. Stool samples were collected from 14,314 patients with diarrhea, who visited hospitals in Gwangju from 2008 to 2012. Samples were screened for rotavirus with Enzyme-Linked Immunosorbent Assay (ELISA) method and rotavirus P (VP4), G (VP7) genotypes were determined by reverse-transcription polymerase chain reaction. And we performed nucleotide sequencing analysis. Among a total of 14,314 samples investigated 1,982 samples (13.8%) were ELISA positive. Genotyping of Rotavirus was performed using 526 rotavirus samples. The most prevalent circulating G genotype was G1 (40.5%), followed by G2 (27.6%), G3 (19.4%), G9 (9.7%), G4 (2.5%) and G12 (0.4%). The predominant type of P genotypes was P[8] (69.6%), followed by P[4] (27.8%) and P[6] (2.3%). In this study, 13 G-P combinations were detected. From 2008 to 2010, G1P[8] was the most prevalent, followed by G3P[8]. Whereas, 2011 and 2012, G2P[4] was the most common, followed by G1P[8]. Rotavirus gastroenteritis is a common disease associated with significant morbidity, mortality and economic burden. Ongoing rotavirus surveillance to understand the distribution of G and P genotypes will be critical for the development of effective prevention measurements.

RESUMEN

UNLABELLED: Dentist can play a significant role in identifying the victims or perpetrators of crime as well as in disasters. Knowledge about the various aspects of forensic science as well as dental and related evidences can help a dental practitioner in assisting the civil agencies in such cases. AIM: To evaluate the awareness and knowledge of forensic odontology among dentists in a metropolitan and a tier 2 city. MATERIALS AND METHODS: Seven hundred and seventy four dentists were included in this survey. Questionnaire was designed to assess the knowledge, aptitude, and status of practice of forensic odontology. Data was analyzed by comparing overall awareness of forensic odontology among dentists in metro and tier 2 city as well as between the different groups. RESULTS: Apart from the source of knowledge, no significant differences were seen in respondents of metropolitan and tier 2 city. Significantly higher proportion of subjects in metro reported journals as source of knowledge (P < 0.001), whereas it was newspaper in tier 2 city (P = 0.001). On comparing the mean scores of knowledge (k), aptitude (a), and practice (p) among different study groups, it was found that all the three scores were highest for practitioner cum academician (PA) group (k - 2.37, a - 0.69, P - 0.17). Knowledge scores were minimum for pure practitioner (PP) group (1.98), and attitude and practice scores of pure academician (A) group were minimum (a - 0.53, P - 0.06). CONCLUSION: Respondents had low knowledge about the applications of forensic odontology in routine practice; hence, steps must be taken to educate the dental practitioners about its clinical applications.

RESUMEN

This study aims at investigating the health and nutritional status of the adults according to frequency of eating out. One day food intake data were collected by 24 hr recall dietary survey and body size, blood pressure and some blood lipids and other constituents were measured on 137 Daejeon metropolitan citizens 20 yrs old and above who visited Chungnam National University Hospital for physical examination during the period of December 6, to December 15, 2008. The frequency of eating out were categorized into four levels: less than once a week, once a week, 2-3 times a week, 4 times a week and above. Body mass Index, waist circumference, blood pressure, blood lipid, blood glucose, GPT and GOT did not showed any significant difference according to the frequency of eating out of the subjects. Though, systolic blood pressures and serum levels of total cholesterol and LDL-cholesterol showed a little tendency to be high in the subjects eating out 2-3 times a week. In the contrary, serum triglyceride level tended to be low in the same group. The subjects eating out 4 times a week and over took more total protein, animal protein, animal fat, phosphorus and vitamin B2 than any other group. Also protein energy ratio was the highest in the group eating out 4 times a week and above and they took more animal food group, other food group, beverages . teas and alcohols than other groups eating out. These results showed that higher frequency of eating out leads to higher intake of protein, fat, phosphorus, animal food groups and other food groups (oils, beverages, seasonings) and to lower intake of vitamin C and plant food groups. It, thus, suggested that the strategy for restaurant business is required to provide the menu substituted animal food by more plant food.
