The Impact

Green infrastructure (GI) is a new term that aims to accomplish sustainable development. It is a platform to achieve a balance between environmental preservation and urban development and achieve economic, social and environmental benefits. However, many countries are suffering from a lack of investment in GI benefits, especially developing countries. Therefore, this study aims to assess the level of attitude among practitioners through assessing their willingness to invest in GI benefits. A quantitative research approach and the questionnaire were designed, containing 17 main benefits of GI to achieve the aim of this study. The questionnaires were distributed manually to the agencies of planning and designing of urban area in Mukalla city. The total number of completed questionnaires entered into this study was 82—the SPSS program approved for results analysis. Relative important index (RII) was used to rank the items, means (X̄) was used to assess the level of attitude among practitioners. Pearson's Chi-square test (χ2) was used to explore the impact of the demographic factors of practitioners on their attitude. In contrast, multiple linear regression was used to predict the relation between attitude and demographic factors. Firstly, the overall means (X̄) revealed that the GI attitude among practitioners in Mukalla city was positive. Secondly, the cross-tabulation revealed that all-male, old and non-government practitioners having a positive attitude, similarly all highly experienced and postgraduate practitioners also had a positive attitude. Pearson's Chi-square test (χ2) showed that experience has no significant influence on GI's economic, social and environmental benefits. Thirdly, multiple linear regression showed that gender and education of practitioners contribute positively toward increasing the level of attitude among practitioners in Mukalla city.

The Impact

There have been efforts to restrict older trucks in many jurisdictions all over the world. The primary goal of the restrictions is to minimize greenhouse gas emissions. In addition to the environmental benefits, it is also possible that the truck age restriction could contribute to the enhancement of traffic safety. Older trucks are subject to longer travel-miles than newer trucks and tend to have higher mechanical failure rates. Extremely few studies have been done to explore the impact of trucks’ age on their crash occurrence due to mechanical problems. This study aims to investigate the association between the truck crashes due to mechanical issues and the truck age. Two approaches are adopted to achieve the objective. First, a chi-square test reveals that the proportions of the mechanical failures among older trucks are higher than those among newer ones ( χ 2  = 256.199, p < 0.0001 ). Second, the modeling results indicate that the number of truck crashes due to mechanical failures is significantly increased by the truck age. The findings suggest that policies restricting older trucks should consider not only environmental effects but also traffic safety benefits.

Socio Demographic Factors

Despite global efforts at promoting environmental sustainability through development of Green Infrastructure (GI) facilities at urban centres; social menaces, depletion and wrong use of green spaces still persists in many developing nations. Indeed, attitude of residents towards the use of these facilities have not been commensurate to the reasons why the GI facilities were created. This study therefore examines the socio-demographic factors associated with visiting GI sites among residents of Lagos Metropolis, Nigeria. Multi-stage sampling technique was used to select 1560 participants in a questionnaire survey. Descriptive statistics was used to explore data distributions while Chi-square test was used to investigate residents’ socio-demographic characteristics associated with visit to green infrastructure sites in the study area. Participants were mostly men (58.6%) and younger than 50 years old (85.8%). Percentages of residents visiting GI facilities for either spiritual exercises (male=26.4%, female=23.8%) or joblessness (male=48.9%, female=52.1%) is higher than percentages of residents visiting GI facilities for recreation/relaxation (male=24.7%, female=24.1%) activities in Lagos Metropolis. The study suggests among others that, the Lagos State government should develop GI facilities to enhance more opportunity for job generation, while more public orientation on positive attitude toward use of GI facilities should be emphasized ABSTRACT Despite global efforts at promoting environmental sustainability through development of Green Infrastructure (GI) facilities at urban centres; social menaces, depletion and wrong use of green spaces still persists in many developing nations.

The increasing prevalence of hypertension each year is a major problem in developing and developed countries. This research was conducted at the post of integrated service of elderly Working area public health center of Simpang Bahjambi, Simalungun Regency. The type of research is a descriptive correlation and using stratified random sampling technique the total sample is 88 respondents. Data were analyzed by using the chi-square test and multiple linear regression tests at 95% confidence. The results of this research show that there is no relationship between the habit of consuming alcoholic beverages with the incidence of hypertension. There was a significant relationship between age, gender, and family disease history. BMI, smoking, and stress with the incidence of hypertension in the elderly. From multiple linear regression tests, found that the most dominant variable correlated significantly with the incidence of hypertension for the elderly is the age factor. It is expected that the society to find information about hypertension disease for the elderly who expected the information is useful and can influence the change of elderly attitude in order to make efforts to control hypertension, besides that the elderly family also willing to make efforts of supervision on family members who suffer from hypertension.

Abstract Background There are fundamental and rapid changes in body shape during pregnancy, some of which persist for an extended time after delivery and may cause dissatisfaction with body shape. Therefore, we conducted this study to determine predictors of body dissatisfaction at six months postpartum based on demographic and fertility factors. Methods This cross-sectional study was conducted on 300 women who referred to seven health centers affiliated with Iran University of Medical Sciences, Tehran, Iran. The sampling was multistage and we collected data from a demographic and fertility questionnaire and Cooper’s Body Shape Questionnaire (BSQ-34). The independent t-test, Mann-Whitney U test, chi-square test, one-way ANOVA, Kruskal-Wallis, Pearson correlation coefficient, and multiple linear regression were used for data analysis. The level of significance was set at P < 0.05. Results The mean age of participating women was 29.77 (standard deviation: 5.9) years. Body dissatisfaction had a statistically significant association with variables such as body mass index (BMI) at six months postpartum, gestational age, the receipt of information about body shape, spouse’s views on the shape of a woman’s body, and mode of delivery. These variables predicted 34% of body dissatisfaction based on multiple linear regression. Conclusion Postpartum body dissatisfaction is related to a several variables. Paying attention to these variables will help to plan and improve postpartum counseling and educational programs.

Purpose: To assess ocular pathologies admitted to Italian Emergency Eye Departments (EEDs) during the COVID-19 pandemic national lockdown in 2020 in comparison with the same period in 2019. Methods: Electronic records of all patients presenting at EEDs of two tertiary-care Eye Centers during the COVID-19 national lockdown in Italy (March 10–May 3, 2020) were compared with the equivalent period in 2019. Main outcomes were patient age, gender, and diagnoses. Statistical analysis included unpaired Student t-tests, Poisson regression, and chi-square test. Results: Overall EED visits significantly decreased by 54.1% during the 2020 lockdown compared to 2019 (851 vs 1854, p < 0.001). During lockdown, patients showed comparable mean age (52.8 years in 2020 vs 53.3 years in 2019, p = 0.52) and significant male gender bias (61.1% in 2020 vs 55.8% in 2019, p < 0.0001). The most frequent pathologies were eye inflammations, trauma-related incidents, and spontaneous acute vitreous detachment. Patients with inflammation, headache/hemicrania, and spontaneous subconjunctival hemorrhages were significantly less, whereas those with trauma-related diagnoses were significantly higher during the lockdown as compared with 2019 ( p < 0.05). The proportion of non-urgent visits decreased from 17% in 2019 to 8% in 2020 ( p < 0.001). Conclusions: During the 2020 lockdown, there was a significant reduction of accesses to EED, especially for non-urgent pathologies. Potentially visual function threatening conditions, such as trauma-related pathologies, retinal detachment or ruptures, and wet AMD, showed lower number of cases but higher or stable proportion relative to the total caseload, suggesting a correct and efficient access to ophthalmic health care during the pandemic period.

Abstract Background In patients with Barrett’s esophagus (BE), endoscopic therapy reduces the risk of progression to invasive esophageal adenocarcinoma (EAC). Data on the impact of endoscopic therapy on patient quality of life (QoL) is limited. Aims We aimed to assess: (1) change in QoL during the course of endoscopic therapy for BE, (2) factors which predict this change, (3) whether achieving complete remission of dysplasia (CRD) or intestinal metaplasia (CRIM) affect the degree of change. Methods We conducted a retrospective observational study using a prospectively maintained database of BE patients treated in Calgary, Alberta from 2013–2020 containing data on demographics, BE disease characteristics and therapeutics, QoL, and follow-up. QoL was determined prior to initiation of therapy and after each treatment session using a validated questionnaire. Descriptive statistics were calculated and change in QoL was compared using a Wilcoxon signed ranks test. Backwards multiple linear regression analysis was performed to determine predictors of change in QoL. Results Of 130 BE patients, 112 (86.1%) were male and 104 (80%) had dysplastic histology or intramucosal carcinoma on index endoscopy. Mean (SD) age was 65.6 (12.0) years. At time of analysis, 76 patients (58.5%) had completed endoscopic therapy, of whom 69 (90.8%) achieved CRIM; 54 patients (41.5%) were still undergoing treatment. There was significant improvement in all QoL measures during the treatment course except for “depression” (Table 1). Patients with CRIM or CRD had reductions in “sleep difficulty” and “negative impact on life” to a significantly greater degree vs patients not achieving CRIM (Δ sleep -0.45 vs 0.0, P=0.002; Δ negative impact -0.4 vs -0.05, P=0.014) or CRD (Δ sleep -0.40 vs +0.60, P=0.002; Δ negative impact -0.40 vs +0.20, P=0.04). Multiple linear regression revealed older age (B=-0.03, P=0.008) and fewer number of EMR sessions (B=0.254, P=0.008) were correlated with greater improvement in QoL. Conclusions Endoscopic therapy improves QoL in BE patients, especially in those achieving CRIM/CRD. Older age and fewer EMRs are correlated with greater improvement in QoL. These results further reinforce the role of endoscopic therapy as the first line treatment of BE and early EAC. Funding Agencies None

Café as an establishment primarily sells refreshing drinks, snacks, and light meals, with coffee being their flagship product. This type of business is steadily multiplying around the city of Tagbilaran, Bohol, Philippines. Customers have linked to business success as well as customer satisfaction and customer loyalty. This study was implemented to analyze the role of customers’ satisfaction in gaining customers’ loyalty, specifically among purposively selected cafés. The quantitative method of research approach was used with the aid of questionnaires. The data gathered were statistically treated making use of frequency, composite means, weighted mean, chi-square test, and Pearson correlation coefficients. The respondents included 210 customers from the purposively selected cafés. Results showed respondents to be very satisfied (VS) for the Product; for the price; for the place; for the service quality; and moderately satisfied (MS) for promotion. Results further showed that there is a significant degree of relationship between customer satisfaction and customer loyalty.

The current work is aimed at generating information on giant crickets and the impact of commonly used pesticides on the natural population of these crickets. Data was collected based on interviews and complemented with field observations. Out of 319 respondents surveyed, 290 were aware of the use of the giant cricket as a food source, and 161 were active consumers. Regarding the availability of the giant cricket, respondents reported that the crickets’ populations were diminishing because of farming practices. About 219 persons reported that commonly used herbicides harm giant crickets at different stages. This could be attributed to the scarcity of this species, as mentioned by 233 respondents. The results showed that 130 respondents were engaged in gathering giant crickets for consumption. This insect gathering is related to soil tilling. Chi-square test showed a significant dependence relationship between herbicides use and cricket scarcity. Although less than a majority (129) of respondents are making regular use of persistent pesticides (herbicides), it has been observed that intensive use of pesticides could become a popular practice in smallholder farming categories. This paper thus suggests the need for training and surveillance concerning the trade of pesticides in the region and proposes further investigations into pesticides residues or traces in collected giant crickets consumed in the study site and in all areas with similar conditions.
