ABSTRACT
Objective: To evaluate the thermal environment of different types of public places and the thermal comfort of employees, so as to provide scientific basis for the establishment of microclimate standards and health supervision requirements. Methods: From June 2019 to December 2021, 50 public places (178 times) of 8 categories in Wuxi were selected, including hotels, swimming pools (gymnasiums), bathing places, shopping malls (supermarkets), barber shops, beauty shops, waiting rooms (bus station) and gyms. In summer and winter, microclimate indicators such as temperature and wind speed were measured in all kinds of places, combined with the work attire and physical activity of employees in the places. Fanger thermal comfort equation and center for the built environment (CBE) thermal comfort calculation tool were used to evaluate the predicted mean vote (PMV), predicted percent dissatisfied (PPD) and standard effective temperature (SET) according to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 55-2020. The modification effects of seasonal and temperature control conditions on thermal comfort were analyzed. The consistency of GB 37488-2019 "Hygienic Indicators and Limits in Public Places" and ASHRAE 55-2020 evaluation results on thermal environment was compared. Results: The thermal sensation of hotel, barber shop staff and the gym front-desk staff were moderate, while the thermal sensation of swimming place lifeguard, bathing place cleaning staff and gym trainer were slightly warm in summer and winter. Waiting room (bus station) cleaning and working staff, shopping mall staff felt slightly warm in summer and moderate in winter. Service staff in bathing places felt slightly warm in winter, while staff in beauty salons felt slightly cool in winter. The thermal comfort compliance of hotel cleaning staff and shopping mall staff in summer was lower than that in winter (χ(2)=7.01, 7.22, P=0.008, 0.007). The thermal comfort compliance of shopping mall staff in the condition of air conditioning off was higher than that in the condition of air conditioning on (χ(2)=7.01, P=0.008). The SET values of front-desk staff in hotels with different health supervision levels were significantly different (F=3.30, P=0.024). The PPD value and SET value of the front-desk staff, and the PPD value of cleaning staff of hotels above three stars were lower than those of hotels below three stars (P<0.05). The thermal comfort compliance of front-desk staff and cleaning staff in hotels above three stars was higher than that in hotels below three stars (χ(2)=8.33, 8.09, P=0.016, 0.018). The consistency of the two criteria was highest among waiting room (bus station) staff (100.0%, 1/1) and lowest among gym front-desk staff (0%, 0/2) and waiting room (bus station) cleaning staff (0%, 0/1) . Conclusion: There are different degrees of thermal discomfort in different seasons, under the condition of air conditioning and health supervision, and the microclimate indicators can not fully reflect the thermal comfort of human body. The health supervision of microclimate should be strengthened, the applicability of health standard limit value should be evaluated in many aspects, and the thermal comfort of occupational group should be improved.

ABSTRACT
Objective In order to strengthen health supervision and management of public places and prevent occurrence of sudden public health events, we explored the effect of quantified and graded management of public places health supervision in Pudong New Area, Shanghai, and drew relevant research results, improving the efficiency of supervision and management in public places. Methods In 2018 from Zhuqiao Town of Pudong New Area Zhuqiao, 200 public places were randomly selected for quantified and graded management of health supervision and quantitative grading including public regulations, tobacco control and appliances, cleaning and disinfection procedures, and according to the score of evaluation results, public health levels A, B, C were rated for those public places.Single factor and multi factor conditional logistic regression model were used for comprehensive analysis to identify related factors affecting the quantitative and graded effect of public health supervision. Results With regard to quantitative and graded health supervision, the relevant knowledge in the 200 public places was updated.By univariate and multivariate conditional logistic regression analysis of multiple factors were ultimately selected 3 factors for public health supervision and quantitative grading management:with or without a health certificate valid (OR=1.121, P=0.026), with or without ashtrays placed in public places (OR=1.012, P=0.032), with or without health inspection report (OR=1.412, P=0.012). Conclusion The influencing factors of quantifying hygienic supervision in public places are mainly effective health certificates, ashtrays in public places and health inspection reports.In future, health supervision of public places should be enhanced in this regard.
ABSTRACT
Objective To determine abundance, distribution and diversity of potential breeding container habitats of the dengue vectors in public places including schools, restaurants, mosques and parks in southwest areas of Penang Island, Malaysia. Methods Premises at restaurants, schools, parks and mosques were surveyed simultaneously and inspected visually for container habitats and production of immature mosquitoes from March 2015 to March 2016. Abundance (mean ± SE) of breeding containers between sites was compared using One-way ANOVA. Independent sample t-test was used to compare total number of Aedes albopictus (Ae. albopictus) and Aedes aegypti (Ae. aegypti) surveyed. Results The surveyed locations yielded a total of 3 741 breeding containers and 19 537 immature mosquitoes from four areas. Concurrent artificial and natural containers produced 78.4% immature Ae. albopictus and 6.3% Ae. aegypti mosquitoes in wet season, with 14.2% Ae. albopictus and 1.1% Ae. aegypti mosquitoes in dry season. Artificial containers accounted for 98.1% of the total containers recorded, with restaurants being the most productive locations (8 012) and schools being the least productive (2 234). Conclusions It was concluded that public places are good sources of potential container habitats of Aedes mosquitoes in Penang Island, Malaysia and Ae. albopictus has exclusively replaced the home-grown Ae. aegypti even in urban areas. Therefore, treatment of artificial containers in such locations is critical in Aedes mosquito control campaigns during dengue outbreaks.

ABSTRACT
Background: India’s Smoke-Free Law (SFL) was implemented in 2004 and reinforced on 2nd October 2008. This research attempts to understand the knowledge and opinion of hospitality venue (HV) managers about second-hand smoke (SHS) and SFL as well as self-reported compliance with SFL in two Indian states. Methods: A survey was conducted among 804 randomly sampled HVs from project STEPS (Strengthening of tobacco control efforts through innovative partnerships and strategies) in Gujarat and Andhra Pradesh, India. Four hundred and three HVs from two districts in Gujarat and 401 HVs from six districts in Andhra Pradesh were selected. The owner, manager or supervisor of each HV was interviewed using a pre-tested structured interview schedule. Association of opinion scales with respondents’ background characteristics was assessed through the analysis of variance (ANOVA) method. Results: Out of the 403 respondents in Gujarat and 401 in Andhra Pradesh, 56.1% and 84.3% had knowledge about SFL respectively. Compliance of HVs with SFL was 21.8% in Gujarat and 31.2% in Andhra Pradesh as reported by the managers. Knowledge about SHS was noted among 39.7% of respondents in Gujarat and 25.4% in Andhra Pradesh. Bivariate results indicated that more educated HV managers showed higher support for smoke-free public places (P < 0.001) and were more concerned about the health effects of SHS exposure (P = 0.002). Conclusion: Complete self-reported compliance with, and knowledge of SFL as well as SHS was not found in Gujarat and Andhra Pradesh. The education level of HV managers is an important determinant to ensure compliance with SFL in public places.
ABSTRACT
Introduction: Exposure to second-hand smoke (SHS) is a serious public health concern. The Indian smoke-free legislation 'Prohibition of Smoking in Public Places Rules, 2008' prohibits smoking in public places, including workplaces. Objective: To measure the status of compliance to legal provisions that protects the public against harms of SHS exposure, identifies the potential areas of violations and informs policy makers for strengthening enforcement measures. Design: A cross-sectional survey in 1401 public places across 11 district headquarters in Himachal Pradesh, India, using a compliance guide developed by partners of the Bloomberg initiatives to reduce tobacco use. Results: In 1401 public places across 11 district headquarters, 42.8% public places had signage; in 84.2% public places, no smoking was observed and in 83.7%, there was absence of smoking accessories such as ashtray, matchbox and lighter . Tobacco litter like cigarette butts was absent in 64.7% of the public places. Overall, at the state level, there was more than 80% compliance on at least three of the five indicators. Among all categories of public places, educational institutions and offices demonstrated highest compliance, whereas most frequently visited public places, eateries and accommodation facilities had least compliance. Conclusions: The compliance to 'Prohibition of Smoking in Public Places Rules, 2008' was variable in various district headquarters of Himachal Pradesh. This study identified the potential areas of violations that need attention from enforcement agencies and policymakers.

Objective To investigate the attitudes of urban and rural community members toward total banning on smoking in public places and to explore the factors associated with these attitudes, in three counties/cities in China. Methods A cross-sectional study was conducted in three counties/cities in 2004, including Xin' an county of Henan province, Anyi county of Jiangxi province, and Mianzhu city of Sichuan province. A total of 5642 residents at age of 18-69 years old were interviewed face-to-face with a uniform questionnaire by locally-trained interviewers, through a random three-stage stratified sampling in each county. Factors were assumed to be associated with attitudes, using chi-square test in univariate analysis and non-conditional logistic regression model in multivariate analysis. Results The prevalence of current smoking among respondents was 44.3%. 80.7% (1379/1709) of the current smokers reported smoking often or sometimes in public places. Only 9.6% (479/4983) of the respondents reported that their indoor workplaces had totally banned on smoking. 43.5% of the respondents supported a total smoking ban strategy in pubic venues. The results of multivariate logistic regression model showed that eight factors were significantly associated with support for the total smoking ban in public places included region, residency, age, gender, education, smoking status, awareness about passive smoking hazards, and hearing of any message on tobacco control through media differences of rates regarding the factors as: residents in urban to rural areas (OR=1.29), elderly to youngsters (30-49 vs. 18-29, OR=1.46; 50-69 vs. 18-29, OR=1.71), female to male(OR=1.27), high-educated to less-educated ones, quitters to current smokers (OR=1.90), nonsmokers to current smokers (OR=2.01). Those who know messages on health hazards of passive smoking (OR=2.26), or heard of message on tobacco control through media (OR= 1.43). Conclusion Results from our study revealed that a thorough smoke-flee policy in public places should be developed and implemented in these three counties/cities.
ABSTRACT
0.05).92.7%of the objects knew that passive smoking was harmful.71.9%knew that passive smoking made people suffering from cardiopathy more possibly.74.9%knew that the wife whose husband smoked were easier to catch lung cancer.And 84.4%knew that the child whose parent s smoked more possibly took asthma or respiration disease. The correct rates of the four knowledge points were different among different gender and the degree of education,which was higher in female than in male,and higher in high education degree than in the other(P
