The problem of this investigation is to determine the part that mental hygiene should and could assume in promoting the general efficiency of the educational program in the elementary grades.

Swine workers in concentrated animal feeding operations (CAFOs) are at risk of developing respiratory illnesses as a result of exposure to a combination of ammonia (NH3), carbon dioxide (CO2), and dust. The purpose of this study was to determine whether the use of a recirculating ventilation system with a filter-type air pollution control (APC) unit (Shaker Dust Collector, United Air Specialists Inc.), selected to control dust, would inadvertently increase NH3 and CO2 concentrations in a farrowing room. During the 2013-14 winter season, NH3 and CO2 concentrations were measured at six fixed locations throughout the farrowing room test site. Direct reading instruments (NH3: VRAE, Rae Systems Inc.; CO2: ToxiRAE Pro, Rae Systems Inc.) were deployed for 24-hour periods throughout the season on 18 randomly selected days. Contaminant concentrations were measured and compared by ventilation status (APC ON: 11 days, APC OFF: 7 days). Ammonia concentrations were above the literature recommended limit (7 ppm) on 13 of the 18 sample days (72%) and even exceeded the threshold limit value (TLV) of 25 ppm on one of the sample days. Carbon dioxide concentrations exceeded the literature recommended limit of 1540 ppm on all 18 sample days, and average concentrations were half of the TLV (2500 ppm). There was no statistically significant difference in NH3 (p > 0.23) or CO2 (p > 0.67) when concentrations were compared by APC status. The results of this study indicate a recirculating ventilation system with filter dust control does not increase NH3 or CO2 concentrations spatially or temporally in the room during operation. Future work will investigate engineering control options to reduce CO2 concentrations in the farrowing room.

The research presented in this doctoral dissertation strived to increase knowledge with respect to respirators performance in the workplace by evaluating particle penetration and breathing resistance (BR) of N95 filtering face-piece respirators (FFRs) under simulated air environmental conditions, determining maximum particle penetration of uncertified dust masks (UDMs) against sodium chloride (NaCl) and BR of UDMs and FFRs when challenged against Arizona road dust (ARD), and evaluating BR of FFRs while performing power washing in swine rooms. A novel test system was used to measure particle penetration and BR of two N95 FFRs under modified environmental conditions. NaCl particle penetration through the FFR was measured before and after the BR test using a scanning mobility particle sizer. BR of the FFR was measured by mimicking inhalation and exhalation breathing, while relative humidity and temperature were modified. BR was evaluated for 120 min under cyclic flow and four temperature and relative humidity air conditions. The BR of the FFRs was found to increase significantly with increasing relative humidity and lowering temperature upstream the FFR (p < 0.001). Measured particle penetration was not influenced by the simulated air environmental conditions. Differences in BR was observed between FFRs indicating that FFRs filtering media may perform differently under high relative humidity in air. In the second study, the maximum particle penetration of five commercially available UDMs was evaluated against NaCl aerosol. Particle penetration was carried out as specified by National Institute for Occupational Safety and Health (NIOSH) to certify N95 FFRs (42 CFR Part 84). Particle penetration was found to vary between 3% and 75% at the most penetrating particle size. In addition, the effect of mass loading on BR of UDMs and FFRs over time was evaluated. ARD was used as the loading dust and BR was measured for 120 min on UDMs and FFRs. BR was found to increase differently between the tested UDMs and FFRs. Further analysis of the UDMs and FFRs external layer suggest that the development of the particle dust cake during mass loading may be influenced by differences of the external layer. In the third study, field research was conducted to evaluate BR of two N95 FFRs while performing power washing in swine rooms. A member of the research team wore the FFR while power washing swine rooms. Every 30 min the team member stopped power washing, BR was measured and power washing continued. At the end of the 120 min trial, the FFR model was switched and the team member continued to power wash the rest of the room. Results demonstrated that BR of the tested FFRs did not increased during power washing in swine rooms (FFR 1, p = 0.40; FFR 2, p = 0.86). Power washing was found to have an effect in the temperature and relative humidity inside the rooms. Based on this study, FFR wearer should expect no increase in BR over 8 hr of power washing, decrease health risk by wearing the FFR and no need to replace the FFR during the power washing task.

Abstract: Background: Dental hygienists can be utilized to provide care to adolescents and young adults in a school-based setting. These dental health care professionals work to improve upon public oral health through educational practices, preventative methods, and referrals. The purpose of this study was to explore the knowledge and perceptions of elementary and middle school staff with regard to the utilization of a dental hygienist in a school setting. Methods: The international review board at approved the following study. A total of eight faculty and staff members from Unicoi County Elementary School and Unicoi County Middle School completed a 14-question survey. Participants included each school’s principal, nurse, physical education/wellness teacher and science teacher or K-6. All surveys were distributed by hand to each school. Results: All eight participants saw a need for their students and would be in support of having a hygienist assigned to their school. Questions in the survey revealed that the facility believed a hygienist would be beneficial, but a full-time nurse was the major care provider in their institution. The schools that had interactions with a dental hygienist could not give the correct answer for how frequently they were coming, what services they were providing, and who was sending the dental hygienists. Discussion: The Northeast Regional Health Office supply dental hygienist for student dental health centered care and application of preventative services. However, there are only three hygienists working with the Northeast Regional Health Office to provide care for seven counties in this region.

In this dissertation, I investigate how eighteenth- and nineteenth-century New England regarded and negotiated the fundamental personal issues of health, hygiene, and sanitation. I employ environmental archaeological and material data, in particular parasite remains, from six New England privy sites: three eighteenth-century sites in Newport, Rhode Island, and three nineteenth-century sites in Boston and New Hampshire. Two eighteenth-century sites belonged to households in the middling stratum of society: one was a poor, lower-class residence. Two nineteenth-century sites were working class- a tenement and a brothel, both in Boston; the third was the Chase House, an upper-class domicile in Portsmouth, New Hampshire. The archaeological and documentary evidence reveal daily choices and their effects. All three eighteenth-century households used chamber pots; the middle-class privies also contained high-quality ceramics. Documents indicate that these families functioned as small-scale merchants. Their prosperity notwithstanding, all three sites revealed parasites, although the amount was considerably less in the middle-class remains than from the poorer household. The nineteenth-century privies reflect that era's inhabitants' increased attention to sanitation and medical treatments; all privies contained more ewers, basins, and medicine bottles. Parasites remained a problem for the working class: both the tenement and brothel privies show moderate levels of parasitic infection. No such evidence was found in the Chase House privy. The material evidence of chamber pots, wash basins, and medicine bottles, places alongside the indications of infection, reveal peoples' active concerns with issues of hygiene and health, and demonstrated also that attention to these issues increased from the eighteenth to nineteenth centuries. Higher levels of household wealth may be linked to lower levels of infection in both eras, probably because of better access to medicines and clean water. The personal involvement revealed by the remains is also reflected in the era's changing social attitudes. The impoverished came to be seen as agents of their own misery whose only hope was to adopt the cleanliness of the upper classes. Poorer people without ready access to better sanitation were regarded as people choosing to live in squalor and, as such, unworthy and beyond help.

This study. concluded in the school year 1961-62, was made to determine how well the health services that were available to the schools of the Stockton Unified School District met the needs of the children attending those schools. It was a further purpose of this study to obtain answers to the following questions: (1) What health services were available to the schools of the Stockton Unified School District? (2) How did the health services that were available to the schools compare with accepted standards, as approved by recognized authorities in the fields of public health and public school health? (3) How well were the available school health services understood by the teachers and administrators of the local school system? (4) What improvements or extensions or the present school health services were indicated by the findings of this study?
