Construction safety remains an ongoing concern, and project managers have been increasingly forced to cope with myriad uncertainties related to human operations on construction sites and the lack of a skilled workforce in hazardous circumstances. Various construction fatality monitoring systems have been widely proposed as alternatives to overcome these difficulties and to improve safety management performance. In this study, we propose an intelligent, automatic control system that can proactively protect workers using both the analysis of big data of past safety accidents, as well as the real-time detection of worker non-compliance in using personal protective equipment (PPE) on a construction site. These data are obtained using computer vision technology and data analytics, which are integrated and reinforced by lessons learned from the analysis of big data of safety accidents that occurred in the last 10 years. The system offers data-informed recommendations for high-risk workers, and proactively eliminates the possibility of safety accidents. As an illustrative case, we selected a pilot project and applied the proposed system to workers in uncontrolled environments. Decreases in workers PPE non-compliance rates, improvements in variable compliance rates, reductions in severe fatalities through guidelines that are customized according to the worker, and accelerations in safety performance achievements are expected.

Objectives : The purpose of this study was to minimize cross infection that can take place within dental office, to make dental workers recognize importance of infection management, and to improve dental-care environment that is exposed to infection. Methods : It conducted the self-reported questionnaire survey on the practice of wearing PPE(personal protective equipment) from April 1, 2008 to May 30 targeting 180 dental workers who are working for dental offices where are located in Jeonnam region. Results : 1. As for research subjects' general characteristics, age was the largest in under 29 years old with 75.0%. It was surveyed to be large in over 5 years(56.1%) for working career, in a city(83.3%) for working region, and in having licence of dental hygienist(75.0%). 2. As a result of surveying the practice of wearing PPE, wearing mask given dental care was surveyed to have the highest practice level with 75.6%. Wearing protective glasses showed the lowest practice ratio with 23.3%. 3. As a result of surveying the difference in the practice of wearing PPE according to general characteristics, the difference according to the working region was surveyed to be the greatest. Conclusions : As the above result, the education of infection management for dental workers needs to be performed continuously even after curriculum of school. Even the in-service education on infection management needs to be vitalized. Also, the necessity was examined for always recognizing and practicing importance of infection by using a method of publishing newsletter via post to dental clinics where are located in rural area, with considering regional deviation.

Personal and static sampling for formaldehyde, wood dust and noise monitoring, in accordance to the equipment running on the day, were carried out throughout wood panel manufacturing process. Even though the exposure level of formaldehyde and wood dust were below than exposure criteria, but the personal protective equipment(PPE) for those should be worn to everyone in the process because of its potential characteristics like carcinogenicity. Also a few local air extraction system above the cutting, grinding sections and organic blending room should be required. Most of the exposures of noise exposure were exceeded permitted exposure criteria, in case of Hopper operators, exposed to maximally 94dB(A) as LAeq 8hr, therefore active controls like PPE, monitoring, isolation etc. are necessary. The main sources of noise were caused on compressed air of the machinery, radio sound and operation noise like running machines, conveying, cutting, sawing, moving vehicles, storing and so on. For the comparison of control criteria in each country, the permitted exposure standards for above hazardous materials and noise in Korea, ACGIH and Australia were discussed. We have recognized that the Korean criteria should be discussed urgently to give the right information to employee and modified, if it is necessary.

This study proposes measures and methods to reduce healthcare associated infections by comparing and analyzing the bacterial contamination level before and after putting on personal protective equipment (PPE) on the test equipment and the contact infected patients getting chest PA projections. Among the 50 inpatients who were diagnosed with C. difficile, MRSA, and VRE, 28 patients who were instructed to undergo chest PA projection and follow-up were chosen, The 3 parts that come in contact with the detector, chin, chest, and hands, were designated for all, and the bacterial contamination level before and after disinfection and before and after putting PPE was determined. Statistical analysis was performed using Medcalc version 14, and quantitative analysis was performed using paired student t-test, with statistical significance being noted at p<0.05. Results for the comparison of the mean values before and after disinfection of the detector, chin (3.000), chest (2.000), and hands (3.430), showed that the number of bacteria after disinfection was lower than it was before disinfection. Analyzing for each part before and after disinfection, there were statistically significant differences for the chin, chest, and hands (p<0.01). Results for the comparison of the mean values before and after putting on PPE, chin (2.202), chest (2.140), and hands (4.213), showed that the number of bacteria after putting on PPE was lower than it was before putting on PPE. Analyzing for each part before and after putting on PPE, there were statistically significant differences for the chin, chest, and hands (p<0.03). As a result, it was confirmed that the number of bacteria after putting on PPE was lower than it was before putting it on. In the future, expanding the research scope for contact infected patients will establish standards for quarantine guidelines depending on the way it spreads, and contribute to the prevention of healthcare associated infections.

Background: Occupational end users of pesticides may experience bodily absorption of the pesticide products they use, risking possible health effects. The purpose of this paper is to provide a guide for researchers, practitioners, and policy makers working in the field of agricultural health or other areas where occupational end use of pesticides and exposure issues are of interest. Methods: This paper characterizes the health effects of pesticide exposure, jobs associated with pesticide use, pesticide-related tasks, absorption of pesticides through the skin, and the use of personal protective equipment (PPE) for reducing exposure. Conclusions: Although international and national efforts to reduce pesticide exposure through regulatory means should continue, it is difficult in the agricultural sector to implement engineering or system controls. It is clear that use of PPE does reduce dermal pesticide exposure but compliance among the majority of occupationally exposed pesticide end users appears to be poor. More research is needed on higher-order controls to reduce pesticide exposure and to understand the reasons for poor compliance with PPE and identify effective training methods.

This study aims to investigate the antecedent of consumer personal preventive equipment purchase behaviour by extending the HBM model after the pandemic. Pandemic related studies have focused on the effect of perceived susceptibility and perceived severity on consumer preventive behaviour, little studies have investigated the antecedents of consumer perceived risk. This study filled the gaps in the previous studies. This study tested all proposed hypotheses among users who have purchase the self-preventive behaviour. In final 253 valid data were collected through online survey for statistics analysis. This study found that consumer's health consciousness significantly impacted consumer's perceived severity of COVID-19 and perceived risk. Perceived risk positively impacted consumer self-preventive equipment purchase intention. In contrast, perceived susceptibility did not significantly consumer perceived risk. Based on these results, the theoretical implication will be offered on the study of health-related studies and will be given insight for disease control center to effectively manage consumer self-preventive behaviour.

Infection risks of handling specimens associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by public health laboratory services teams were assessed to scrutinize the potential hazards arising from the work procedures. Through risk assessments of all work sequences, laboratory equipment, and workplace environments, no aerosol-generating procedures could be identified except the procedures (mixing and transfer steps) inside biological safety cabinets. Appropriate personal protective equipment (PPE) such as surgical masks, protective gowns, face shields/safety goggles, and disposable gloves, together with pertinent safety training, was provided for laboratory work. Proper disinfection and good hand hygiene practices could minimize the probability of SARS-CoV-2 infection at work. All residual risk levels of the potential hazards identified were within the acceptable level. Contamination by gloved hands was considered as a major exposure route for SARS-CoV-2 when compared with eye protection equipment. Competence in proper donning and doffing of PPE accompanied by hand washing techniques was of utmost importance for infection control.

The purpose of this study was to obtain qualitative data on Korean-American dry cleaners' concerns about work-related health and safety and their attitudes toward the use of PPE(Personal Protective Equipment). Two focus group discussions were conducted with convenient samples of Korean-American drycleaners in middle-eastern state. A total of 13 individuals participated in two focus groups. Participants had concerns as both owners and workers. As owners, they were concerned mostly about compliance of environmental regulation and economic depression. The participants knew very little about the hazards of chemical exposure and expressed vague concerns about chemical exposure and health. Majority of participants do not use PPE and had no intention of using it in the future because of their limited knowledge about the hazardous nature of chemical exposure. The findings from this study would guide the development of intervention to increase drycleaners knowledge of chemical exposure and use of PPE.

Air pollutants of concern include traffic-related air pollution, including particulate matter in respirable coarse and fine size fractions. There are no critical studies to date into associations between knowledge, awareness, and attitudes in using proper respiratory masks and prevalence of respiratory symptoms among urban street vendors in Thailand. In this study, we estimated adverse respiratory health outcomes among street vendors, in particular young adults, in Bangkok, Thailand, using a self-report questionnaire. Street vendors, who were not currently smoking and not having known diagnosed respiratory diseases, were recruited. They were selected from selected roadsides at Chong Nonsi, Bangkok. Participants (n = 30) reported having lower respiratory (50%), upper respiratory (37%), and other symptoms (70%). Also, 53% of participants had never used respiratory personal protective equipment (PPE: masks). Among those using PPE, all used masks not proper for particulate matter. Results suggested knowledge, awareness, and attitudes concerning proper PPE use needs to be increased among street vendors in Bangkok, Thailand.
