Connecting to the disaster risk reduction (DRR) studies, community-based initiatives are found to be more effective in both developed and developing countries, with a specific focus on the empowerment of local communities to build resilience. Building on social capital theory, the paper investigates on local knowledge (LK) practices experienced by the actors in an emerging economy using the community-based flood risk management (CB-FRM) approach. The qualitative research method was used by collecting data from focused group discussions, and interviews with the key informants including actors from local governments and non-government organizations. Additionally, informal discussions, field visits, and desk studies were undertaken to support the findings. The findings reveal that the local communities carry out various local knowledge experiences to respond during disaster management phases. They own a creative set of approaches based on the LK and that empowers them to live in the flood-prone areas, accepting the paradigm shift from fighting with floods to living with that. The local actor’s involvement is recognized as an essential component for CB-FRM activities. Yet, their program’s implementation is more oriented towards humanitarian assistance in emergency responses. Even, they often overlook the role of LK. Additionally, the results show a high level of presence of local communities during the preparedness and recovery phases, while NGOs and local governments have a medium role in preparedness and low in recovery phase. The lack of local ownership has also emerged as the major challenge. The research provides valuable insights for integrated CB-FRM policies by adopting to LK practices. 展开更多

Objective: Given the unique cultural background, way of life, and physical environment of the Tibetan Plateau, this study aims to investigate the effects of health education using problem-based learning (PBL) approaches on the knowledge, attitude, practice, and coping skills of women with high-risk pregnancies in this region. Methods: 76 high-risk pregnancy cases were enrolled at Tibet’s Linzhi People’s Hospital between September 2023 and April 2024. 30 patients admitted between September 2023 and December 2023 were selected as the control group and were performed with regular patient education. 46 patients admitted between January 2024 and April 2024 were selected as the observation group and were performed regular patient education with problem-based learning approaches. Two groups’ performance on their health knowledge, attitude, practice and coping skills before and after interventions were evaluated, and patient satisfaction were measured at the end of the study. Results: There was no statistical significance (P P P Conclusions: Health education with problem-based learning approaches is worth promoting as it can help high-risk pregnant women in plateau areas develop better health knowledge, attitude and practice and healthier coping skills. Also, it can improve patient sanctification. 展开更多

Based on rural household data collected in two rounds of the China Household Finance Survey(CHFS)in 2015 and 2017,respectively,this paper presents the likely impact of financial literacy and capability against risks on the breadth and depth of participation by rural households in risky financial markets.After instrumental variables are used to solve endogenous problems,we find that a good command of financial knowledge and a higher risk management level could significantly increase the probability and proportion of rural households investing in risky financial assets.A mechanism analysis further reveals that financial knowledge motivates rural households to engage in financial investments by helping them evaluate their capability to guard against risks.After multiple dimensions of indicators are employed to measure financial knowledge,the estimated results remain stable.In view of this,we have put forward some policy suggestions to increase the property income of rural households and promote the rural financial market. 展开更多

In West Africa, smallholder farmers in indigenous agricultural societies typically hold considerable knowledge. Therefore, this study was conducted in West Atacora of Benin Republic to assess the drivers of farmers’ perceptions of climate change risk. We used a random sampling technique to select 360 households’ heads who were interviewed regarding different climate change risks perception. Binomial logistic regression was used to assess the drivers of farmers’ perceptions of climate change risks. The results showed that the farmers in drier areas had a higher perception of the global risk of climate change than those in humid areas. The same trend was observed for the seven different individual’s climate change risk investigated. The study identified also membership of farm organizations as main sociodemographic characteristic that explains farmers’ perception of climate change risk perception. These findings are helpful tools to sensitize the local people on climate change risk and cope with the risk in agricultural lands. 展开更多

Introduction: In 2008, cardiovascular disease (CVD) accounted for one in three deaths in the United States. Epidemiological analyses suggest that two or more risk factors are the indicator of high risk and/or poor CVD outcomes. Knowledge of heart attack and stroke symptomology has been the focus of much research based on the assumption that accurate identification of an event is critical to reducing time to treatment. There is a paucity of research showing a clear association between knowledge of heart attack and stroke symptomology, risk factors, and mortality rates. In this study, we hypothesized that high stroke and heart attack symptomology knowledge scores would correspond to lower stroke or CVD mortality rankings as well as to a lower prevalence of two or more CVD risk factors. Methods: State was the unit of analysis used to examine data from two different sources and combined into a customized database. The first source was a multiyear Behavioral Risk Factor Surveillance Survey (BRFSS) heart attack and stroke symptom knowledge module database. CVD and stroke mortality data used came from the American Heart Association’s (AHA) 2012 Heart Disease and Stroke Statistics Update. Spearman’s Rho was the test statistic. Results: A moderate negative correlation was found between high heart attack and stroke symptom knowledge scores and the percentage of adults with two or more CVD or stroke risk factors. Likewise, a similar correlation resulted from the two variables, high heart attack and stroke symptoms knowledge score and CVD mortality rank. Conclusions: This study demonstrated a significant relationship between high heart attack and stroke symptom knowledge and lower CVD mortality rates and lower prevalence of two or more CVD risk factors at the state level. Our findings suggest that it is important to continue education efforts regarding heart attack and stroke symptom knowledge. Pharmacists are one group of health care providers who could enhance the needed public health education efforts. 展开更多

Objective: To relate cardiovascular risk factor knowledge to lifestyle. Methods: In this cross-sectional study, food consumption and lifestyle characteristics were recorded using mailed questionnaires. The dietary pattern was described using the Mediterranean Diet Score (MDS). An open ended questionnaire without predefined choices or answers was used to capture cardiovascular knowledge. Results: Lack of physical activity, smoking and eating too much fat were the 3 most cited potential cardiovascular risk factors, while being overweight, eating too much salt and a low consumption of fruits and vegetables were the least cited risk factors. Age, Body Mass Index, physical activity, smoking, income and dietary habits were not consistently associated with knowledge of risk factors. A low socioeconomic position as measured by the indicator education was associated with a lower knowledge of established and modifiable cardiovascular risk factors. Conclusions: Risk factor knowledge, an essential step in prevention of CVD, is not systematically associated with a healthier lifestyle. The findings of this study confirm that there is a gap between risk factor knowledge and lifestyle. 展开更多

Objective:To investigate the interrelationship between cardiovascular health awareness,risk perception,behavioural intention,and INTERHEART risk stratification in a middle-aged adult population in Malaysia.Methods:A cross-sectional survey with convenience sampling was conducted during November 2022 and January 2023.Participants completed validated questionnaires assessing cardiovascular health awareness,risk perception of cardiovascular diseases,behavioural intention towards adopting healthy habits,and INTERHEART risk stratification score(IHRS)based on established risk factors.A total of 602 respondents were included in the final analysis.Data were analysed with independent t-test/one-way ANOVA or Mann-Whitney/Kruskal-Wallis to test the differences,Pearson correlation or linear regression test to analyze the association of independent and dependent variables.Results:There was a significant positive correlation between medical knowledge related to cardiovascular disease(CVD)and knowledge related to CVD risk prevention,risk perception,behavioural intention and IHRS(P<0.05,Pearson correlation).Notably,individuals with higher IHRS tended to have lower knowledge related to CVD and CVD risk prevention,risk perception,and behavioural intention.Males,laborers,active/former smokers,individuals with lower household income and educational levels,those involved in occupations not related to the healthcare sector,and those who did not receive the CVD health brochure or are unaware of health self-assessment tools are likely to have lower levels of knowledge,risk perception,and poorer behavioural intention regarding cardiovascular health(P<0.05,one-way ANOVA).While educational level,smoking status,awareness about CVD poster,self-assessment tools were repeatedly significantly associated with knowledge related to CVD and CVD risk prevention,risk perception,behavioral intention and/or IHRS(P<0.05,linear regression).Conclusions:These findings underscore the importance of promoting cardiovascular health awareness and risk perception among middle-aged adults to foster positive BI and reduce CVD risk.Tailored interventions targeting specific risk factors identified by INTERHEART may enhance risk stratification accuracy and facilitate targeted preventive strategies. 展开更多

Computational techniques have been adopted in medi-cal and biological systems for a long time. There is no doubt that the development and application of computational methods will render great help in better understanding biomedical and biological functions. Large amounts of datasets have been produced by biomedical and biological experiments and simulations. In order for researchers to gain knowledge from origi- nal data, nontrivial transformation is necessary, which is regarded as a critical link in the chain of knowledge acquisition, sharing, and reuse. Challenges that have been encountered include: how to efficiently and effectively represent human knowledge in formal computing models, how to take advantage of semantic text mining techniques rather than traditional syntactic text mining, and how to handle security issues during the knowledge sharing and reuse. This paper summarizes the state-of-the-art in these research directions. We aim to provide readers with an introduction of major computing themes to be applied to the medical and biological research. 展开更多

BACKGROUND We recently demonstrated that the odds of contracting coronavirus disease 2019(COVID-19)in patients with celiac disease(CeD)is similar to that of the general population.However,how patients with CeD perceive their COVID-19 risk may differ from their actual risk.AIM To investigate risk perceptions of contracting COVID-19 in patients with CeD and determine the factors that may influence their perception.METHODS We distributed a survey throughout 10 countries between March and June 2020 and collected data on demographics,diet,COVID-19 testing,and risk perceptions of COVID-19 in patients with CeD.Participants were recruited through various celiac associations,clinic visits,and social media.Risk perception was assessed by asking individuals whether they believe patients with CeD are at an increased risk of contracting COVID-19 when compared to the general population.Logistic regression was used to determine the influencing factors associated with COVID-19 risk perception,such as age,sex,adherence to a gluten-free diet(GFD),and comorbidities such as cardiac conditions,respiratory conditions,and diabetes.Data was presented as adjusted odds ratios(aORs)RESULTS A total of 10737 participants with CeD completed the survey.From them,6019(56.1%)patients with CeD perceived they were at a higher risk or were unsure if they were at a higher risk of contracting COVID-19 compared to the non-CeD population.A greater proportion of patients with CeD perceived an increased risk of contracting COVID-19 when compared to infections in general due to their CeD(56.1%vs 26.7%,P<0.0001).Consequently,34.8%reported taking extra COVID-19 precautions as a result of their CeD.Members of celiac associations were less likely to perceive an increased risk of COVID-19 when compared to non-members(49.5%vs 57.4%,P<0.0001).Older age(aOR:0.99;95%CI:0.99 to 0.99,P<0.001),male sex(aOR:0.84;95%CI:0.76 to 0.93,P=0.001),and strict adherence to a GFD(aOR:0.89;95%CI:0.82 to 0.96,P=0.007)were associated with a lower perception of COVID-19 risk and the presence of comorbidities was associated with a higher perception of COVID-19 risk(aOR:1.38;95%CI:1.22 to 1.54,P<0.001).CONCLUSION Overall,high levels of risk perceptions,such as those found in patients with CeD,may increase an individual’s pandemic-related stress and contribute to negative mental health consequences.Therefore,it is encouraged that public health officials maintain consistent communication with the public and healthcare providers with the celiac community.Future studies specifically evaluating mental health in CeD could help determine the consequences of increased risk perceptions in this population. 展开更多

Inconsistent condom use among persons on antiretroviral treatment (ART) is a major public health concern because of the risk of HIV transmission. This study examined the association between socio-demographic variables and knowing partners’ HIV status, multiple sex partners, and consistent condom use among 400 HIV-infected adults who had received ART for at least six months in Johannesburg, South Africa. The study used a cross-sectional survey and a structured interviewer administered questionnaire. Over half (n = 225, 56.3%) of participants were on ART for more than two years. Two thirds (n = 234, 63.2%) were aware of partner’s HIV status. Over a third (n = 136, 34.0%) reported having more than one sex partners. Three quarters (n = 279, 75.8%) reported consistent condom use with regular partner. Discussing HIV testing (aOR = 2.28, CI: 1.31 -3.95), awareness of partner’s HIV status (aOR = 2.59, CI: 1.50 -4.46), level of education (aOR = 0.64, CI: 0.42 -0.98), and duration on ART (aOR = 0.71, CI: 1.31 -3.95) were predictors for consistent condom use. Awareness of partner’s HIV status was associated with multiple partnership (aOR = 0.38, CI: 0.21 -0.66), living with partner (aOR = 4.75, CI: 2.86 -7.91), discussing HIV testing (aOR = 2.43, CI: 1.48 -3.99), and duration on ART (aOR = 2.04, CI: 1.43 -2.92). While gender (aOR = 5.68, CI: 3.46 -9.34), marital status (aOR = 0.44, CI: 0.25 -0.77), and awareness of partner’s HIV status (aOR = 0.52, CI: 0.30 -0.89) were associated with multiple partnerships. Risky sexual behaviours occurred in all types of partners and knowing partner’s HIV status was a predictor for consistent condom use with all types of partners. It is essential that HIV prevention strategies create an enabling environment for disclosure and reductions of risky sexual behaviours by HIV-infected persons on ART. 展开更多

This paper presents explicit formulae giving tight upper and lower bounds on the expectations of alpha-unimodal random variables having a known range and given set of moments. Such bounds can be useful in ordering of random variables in terms of risk and in PERT analysis where there is only incomplete stochastic information concerning the variables under investigation. Explicit closed form solutions are also given involving alpha-unimodal random variables having a known mean for two particularly important measures of risk—the squared distance or variance, and the absolute deviation. In addition, optimal tight bounds are given for the probability of ruin in the collective risk model when the severity distribution has an alpha-unimodal distribution with known moments. 展开更多

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which is widely referred to as “COVID-19”, has been infecting more than 5.5 million over 144 countries. A vaccine is considered to be the most awaiting intervention and hundreds of global R&D institutions engaged in unprecedented speed to develop the vaccine. The availability of COVID-19 vaccines may not translate into its uptake. Although governments will provide the vaccines, their uptake is voluntary. <strong>Objective:</strong> This study was carried out to evaluate the level of acceptance of COVID-19 vaccine and it’s determinants among high risk groups for severe COVID-19 infection living in Mogadishu Somalia.<strong> Methods:</strong> The study was cross-sectional, descriptive analysis conducted to obtain reliable information about the acceptance of COVID-19 vaccine and it is determinants among high-risk groups living in Mogadishu, Somalia. The calculated sample size was 404 using Cochran’s formula = Z<sup>2</sup>p(1 <span style="white-space:nowrap;"><span style="white-space:nowrap;">&minus;</span></span> p)/d<sup>2</sup> and addition of 5% non-respondent rate. According to PESS population estimate in 2020, there are 17 districts. We grouped them into 2 strata and through simple random sampling one district was selected from each strata. After randomly selecting the two districts, three sub districts were randomly selected from each and then every second house (1, 3, 5) in the main roads will be selected. If target population were not found in the second selected house, the next house will be taken until sample size is obtained. <strong>Results:</strong> 59.4% of respondents were willing to accept and take vaccination while 40.6% of them were not accepting the vaccination. Being afraid of the side effect was the most common reason for not accepting the vaccine <strong>Conclusion: </strong>More than one third of respondents (40.6%) were not willing to accept the vaccination, knowledge towards COVID-19 was strongly associated with acceptance level of COVID-19 vaccine. <strong>Recommendation:</strong> Multi-sector organized awareness campaigns involving FMH as well as local authorities and civil society to enhance level of knowledge of community towards COVID-19. 展开更多
