Abstract:
Purpose The purpose of this paper is to evaluate the hygienic design of a scalable unit for supercritical carbon dioxide drying of food. Design/methodology/approach For the purpose of this study, a checklist has been developed, covering requirements from sanitary standards and industry-tailored guidelines. Beyond hygienic design, failure mode and effects analysis of the results were performed to assess the potential food safety risks that may arise from failures to hygienic design requirements. Findings The overall score of the hygienic design was 46 percent. This kind of evaluation revealed two types of nonconformities. The first type was related to inadequate sanitary procedures. The second type was associated to design failures. Research limitations/implications The highest risk was designated to problems related to cleaning and sanitation followed by risks associated with the formation of dead zones and biofilms. Practical implications This study provides valuable insight to engineers and food technologists on hygienic design issues. Originality/value Application of a similar methodology was used for evaluating hygienic design of other non-thermal food technologies.

Abstract:
Objective To assess hand hygiene compliance in selected primary hospitals in Ghana. Design A cross-sectional health facility-based observational study was conducted in primary health care facilities in five regions in Ghana. A total of 546 healthcare workers including doctors, nurses, midwives and laboratory personnel from 106 health facilities participated in the study. Main outcome measures The main outcome measures included availability of hand hygiene materials and alcohol job aids; compliance with moments of hand hygiene; and compliance with steps in hygienic hand washing. These were assessed using descriptive statistics. Results The mean availability of hand hygiene material and alcohol job aids was 75% and 71% respectively. This was described as moderately high, but less desirable. The mean hand hygiene compliance with moments of hand hygiene was 51%, which was also described asmoderately high, but less desirable. It was observed that, generally, hand hygiene was performed after procedures than before. However, the mean compliance with steps in hygienic hand washing was 86%, which was described as high and desirable. Conclusion Healthcare workers are generally competent in performance of hygienic hand washing. However, this does not seem to influence compliance with moments of hand hygiene. Efforts must therefore be made to translate the competence of healthcare workers in hygienic hand washing into willingness to comply with moments of hand hygiene, especially contact with patients.

Abstract:
An experiment was performed on oral bacteria removal using the design variables, which included the three-segment rotor speed of the testing device and three types of stainless steel meshes (with different layers). The overall hygienic results showed an effect of up to 95% bacteria removal, and some combinations had 100% hygienic effect. The study proposed that the use of nanobubble generated by a high-density stainless-steel mesh-manufactured nozzle removes dental bacteria. In addition, the device could also be used for auxiliary oral hygiene to decrease the frequency of future medical visits due to periodontal diseases or to enable the device to assist patients with severe periodontal disease more conveniently for oral hygiene.

Abstract:
The work is devoted to the study of hygienic aspects of automobile filling station location in rural areas in modern conditions in order to minimize the negative impact of AFS on health and living conditions of the population. A theoretical generalization of the world experience of gas station design and operation was made. New data on the current ecological and hygienic state of design (location) of modern gas stations in Ukraine and their impact on the environment, health and living conditions of the population. Based on the materials of the work, the hygienic criteria for placing gas stations and their classification have been improved. Classification conditions for the definition of sanitary protection zones for gas stations of different capacity have been developed, which allowed to improve the legal and information-methodological base on hygiene planning and development of settlements in the design of gas stations of different types and capacities and develop a new SPZ standard for gas stations and filling stations. On the basis of the conducted researches the differentiated approach is offered and the procedure of the decision of questions concerning placement of gas stations in the territory of settlements is developed.

Abstract:
The problem of the environment in the inhabited area, in particular of the hygienic-sanitary comfort, are current topics of concern for the builders. The interest of the authors meets the requirements of the tenant. In general, it seems that the cause of the hygienic-sanitary discomfort of the inhabited environment would be the faulty execution of the construction or an inconsistent architectural conception; the current paper presents several factors that cause this discomfort, the tenant being just one of them. The result of faulty operation/utilization of living spaces is inadmissible for those who live there, both materially and with repercussions on their health. Additionally, this paper demonstrates the deficiency of the existing energy performance certificate. The results of our research offer real solutions in eliminating, solving, and correcting the hygienic-sanitary discomfort of the environment inside the buildings; this can be achieved by designing, executing and operating spaces correctly, adequately and optimally, ensuring a healthy environment. The authors propose to improve the norms of protection of the built environment, by modifying the related energy performance legislation/certificate; moreover, new and real practical solutions have been suggested by the authors for the prevention and remediation of hygienic-sanitary discomfort.

Abstract:
Purpose Many Japanese hay fever (HF) sufferers wear a hygienic face mask to prevent pollen inhalation, but most find it very uncomfortable. The purpose of this paper is to identify the problems associated with mask wearing through repeated surveys. This information can be used in the improved design of a hygienic face mask that can be worn without discomfort by HF sufferers. Design/methodology/approach In 2009 (n=1,519), 2012 (n=2,994), and 2015 (n=3,213), repeated surveys of university students were conducted. HF sufferers were queried regarding symptoms, countermeasures, and problems associated with wearing a hygienic face mask. Holistic perspectives for each year were obtained by a co-occurrence analysis of the aggregated data. The triplet co-occurrence of specific problems was compared among the surveys using the χ2 test. Temporary and contemporary co-occurrence relationships were also determined. Findings Most Japanese university students with HF wore a hygienic face mask. In each survey, the most common problems associated with mask use were related to its thermal, hygroscopic, and air-flow properties. Contemporary problems with co-occurrence relationships were “humidity,” “breathing difficulty,” and “mist over eyeglasses” for males and, “humidity,” “breathing difficulty,” and “make-up coming off” for females. Originality/value The results of this study will contribute to improving hygienic face mask design. The co-occurrence of contemporary problems related to mask use was identified by comparing the results obtained in each year. The thermal, hygroscopic, and air flow properties of the mask cause these problems, and the air gap between the mask and the wearer’s face influences the inherent physical properties of the mask. To measure the air gap, a suitable hydrostatic pressure-balanced experimental method was applied, and the data were demonstrated experimentally.

Abstract:
The article considers the hygienic factors that form the comfort of living and affect the consumer properties of the living space. The processes of life of the population, its demographic and social reproduction are provided in the living environment, the material conditions of which determine the full value of these processes. Satisfaction of biological needs requires the availability of places for sleep, food, hygiene, recreation and is determined by the comfort and convenience of housing, adequate human connections with the natural environment. Regulation of hygienic factors of placement, planning, construction and operation of housing is a priority to ensure favorable living conditions. Improving the quality of human life is directly related to solving an important socio-economic problem - providing housing in accordance with modern requirements, which take into account the material, social, spiritual, household needs and physical capabilities of man. Comfortable housing takes into account anthropometric parameters, protects from adverse weather conditions, provides an optimal microclimate, appropriate conditions for work and rest, raising children, various household processes and more. Optimal room performance ensures the absence of additional human energy costs for adaptation and adaptation to external conditions and includes heat and humidity, insolation, aeration, cleanliness and freshness of air, visual and noise comfort. To create a comfortable home, it is necessary to take into account all the components of hygienic requirements when using a set of architectural, planning, sanitary and organizational measures that provide the normative values of living comfort and do not adversely affect human health. Hygienic indicators have a direct impact on the level of quality of residential buildings, providing individual living comfort and overall social efficiency of the population, are the main purpose of optimizing the design and construction of residential buildings.

Abstract:
It is established that in the stall period (November - March) the microclimate of the cowshed is 4.0 points, which complies with the engineering design conditions, to improve the parameters it is necessary to optimize the conditions regarding the concentration of harmful gases in the air and microbial contamination. Well-timed faeces disposal and air ventilation control will optimize these parameters. It is proven that the thermal balance of the building depends on the created conditions of comfortable keeping of cows and their number in the building, as well as heat loss through the enclosing structures: gates, windows, ceiling, floor and walls, the thermal balance in the cowshed is made for the outside temperature of (-4,3 ° С). Since sanitary and hygienic conditions of cow housing do not meet the optimal design and technological regime, and the amount of microorganisms in the air of the room is above norm and negatively affects the health of cattle, it is necessary to implement integrated elements of technology in the process of commercial milk production and rationalize the schedule while maintaining standards of technological design.

Abstract:
For food processing equipment, welding uses heat to fuse together the various pipes and pieces of stainless steel. The quality of the weld is a determining factor in whether or not the product meets hygienic design standards for the food processing industry. When fabricating food processing equipment, weld quality is extremely important to maintain the integrity of the products being processed. A weld does not meet hygienic design standards if there is potential for contamination that can result from cracks, crevices, 90-degree angles, corrosion or over-stresses surfaces in the processing equipment. When product is stuck in a crevice it becomes very difficult to remove through regular cleaning leaving the potential for bacteria to build up and contaminate additional food products.

Abstract:
The building design and material selection has to respect the environmental requirements of indoor air quality and indoor hygiene parameters. As the first stage of building design is the most important for final indoor air quality more and more by clear constructional architecture the benefit of environmental safety, good indoor air quality for health and productivity are dominant. Nowadays the interior surface materials have received greatest attention as sources of indoor air pollution. The major pollutants in indoor air are volatile organic compounds emitted from materials and building products. Volatile organic compounds, or VOCs, are among the most complex and troubling indoor air pollutants. Manufactured and synthesized products often release large quantities of VOCs, some of the compounds they release, such as benzene, styrene, formaldehyde, and toluene, may be irritating, toxic, or even carcinogenic. VOCs emitted can become attached to other surfaces in the space, especially fabrics, and then be re-emitted over time. The impact of interior surface materials on air quality and indoor hygiene is discussed within the paper. The building design concerning to heath of occupants and hygienic performance regime can be realized only by interdisciplinary team of professionals respecting the environmental building and indoor design.

Abstract:
Modern radioecological studies to assess the effect of natural radiation on the human body have shown that at the moment of development of society, the main contribution to the exposure of the population is made by natural sources of ionizing radiation, while from 50 to 90 % of the dose load are caused by the gas radon-222 (222Rn) and daughter products of its decay. This paper presents the results of radiation-hygienic monitoring of the potentially radon-hazardous territory of the city of Baley, Trans-Baikal Territory. The measurement of the volumetric activity of radon (OARn) was carried out in the premises of residential and public buildings by the integral method using track exposure meters REI-4. According to the indicator of the equivalent equilibrium volumetric activity of radon (EROARn), a radiation-hygienic assessment of the premises and the calculation of potential dose loads on the population living in this territory were carried out. Studies have shown that OARn in residential and public buildings depends on the geological characteristics of the territory, on the design and design of buildings and structures, and on the building materials used. It was found that the main criterion for assessing the potential radon hazard of territories is the value of OARn in rooms on the 1st floors of buildings. According to the degree of potential radon hazard, the territory of the city of Baley can be conditionally divided into 3 types: 1 type – the territory located on a geological fault; Type 2 – the southern part of the city, represented by sedimentary rocks; Type 3 – the northern part of the city, represented by rocks of the basic gabbroid group with a low content of natural radionuclides. The types of buildings and structures and the type of building materials affect the dose load, but do not determine it.

Abstract:
Introduction. Currently, in connection with the large-scale introduction of the electronic educational resource in the educational process, it is especially relevant to search for optimal characteristics of presenting information on screens, taking into account the specifics of the electronic devices and age-related physiological features of the users’ visual system. The aim of the study was a physiological hygienic assessment of the impact of the font design of e-texts, presented on a laptop, on the psychophysiological state of students in grades 10-11. Material and methods. Psychophysiological testing of 43 schoolchildren in grades 10-11 without pathology of the vision organ was carried out on the NS-Psychotest complex, including the method of critical flicker fusion frequency to assess the state of the central part of the visual analyzer and the response to a moving object to determine the degree of the balance in nervous processes. The influence of reading illogical texts typed by a school headset was studied with a font size of 14, 12 and 10 points and a one-time reading of 200, 400 and 600 characters. Laptop Lenovo IdeaPad 720S-15 was used for the presentation of information. Results. High-grade schoolchildren were established to have the initial fatigue both of the visual analyzer and the nervous system as a whole. Boys showed better indices of the critical flicker fusion frequency than girls. Most schoolchildren had a balanced type of the inhibition and excitement processes. Methods of presenting information in electronic textbooks were shown to affect the psychophysiological state of high schoolchildren and may carry risks to their health. The hygienically rational design of electronic educational texts promotes the optimization of the psycho-functional state of the high schoolchildren’s body. Conclusion. The obtained results allow substantiating hygienic requirements for the font design of e-learning publications at the third stage of education.

Abstract:
A mobile fish vending trolley has been designed and developed by Indian Council of Agricultural Research (ICAR) - All India Coordinated Research Project on Plasticulture Engineering and Technology (AICRP on PET) centre at ICAR-Central Institute of Freshwater Aquaculture (ICAR-CIFA), Bhubaneswar to aid the fisher folks for vending their fish harvests in hygienic condition. The unique selling proposition (USP) of the vending unit is its unibody design, where icebox for storing fish, 20 l capacity water storage tank for hand washing, tool box, fish cutting deck and waste collection chambers are integrated into the unit. The icebox can store 100 kg of fish in ice which can be sold in a single day by the fisher folks. The complete unit of mobile fish vending carriage is fabricated with fibre reinforced plastic (FRP), because of its high strength compared to other plastics, ease of fabrication and good insulation property of fiberglass (i.e. thermal conductivity= 0.04 w/mK at normal room temperature 25 ºC). The dimensions of the carriage unit is 4.0’x2’9”x2’6” in which half portion is dedicated for the insulated ice box and the remaining portion houses the fish cutting deck, waste collection chamber and tool box. This fish vending trolley would be a boon for the marginal fish vendors, who want to sell fish in a hygienic condition and to increase income generation potential by selling 100 kg fish in a day.

Abstract:
Introduction. The implementation of the federal project “Digital School” provides for the creation of a secure digital educational environment. There are needed hygienic standards for the use of electronic educational facilities in schools. The purpose of the study: Justification of approaches, methods, and indices of the hygienic rating of electronic means for education for children and adolescents. Material and methods. A nonrandomized controlled study was performed using a natural hygienic experiment. Analyzed materials included the results of surveys of children, data on the physical parameters of the educational environment, the font design of electronic textbooks, the psychophysiological state of adolescents when reading texts from screens of electronic educational tools. Results. The behavior of high school students in a digital school is associated with a whole complex of health risk factors, which significantly change the lifestyle of adolescents. Peculiarities of the impact of the font design on the functional state, cognitive functions, and well-being of students depending on the level of education and the type of electronic device are revealed. Signs of fatigue for students in grades 5-9 were observed when reading at a time texts in 12-point font with a volume of 400 characters, at 10 points in a volume of 200 characters and all texts with a capacity of 600 characters; in high school students - when reading text in a font of 10 points with a volume of 600 characters. A more favorable effect of the visual work of students on a tablet compared to a laptop has been established. The hygienic requirements for the font design of electronic textbooks for grades 5-11 are justified. Conclusion. Hygienic regulation of the use of electronic educational tools should be based on an integrated approach, including the assessment of behavioral risk factors for children’s health in the context of digitalization of their livelihoods and the prevalence of electronic teaching aids, the examination of the effects of electromagnetic radiation in a digital environment, the use of font typography, as well as indicators of psycho-functional state Learning when working with electronic learning tools.

Abstract:
Purpose The purpose of this paper is to study the microbiological quality of raw milk delivered by 17 vending machines (VM) owned by different Slovenian milk producers. Design/methodology/approach For the determination of hygiene-technical conditions of VM, an observation list that included criteria for estimation of hygiene-technical suitability was made. A total of 51 milk samples were collected in three different seasons. The swabs and the cleaning liquid (eluates) of dispensing nozzles and chambers were also sampled. The main groups of microorganisms were determined by colony count technique according to international standards in all collected samples. Findings The aerobic colony count was higher than 100,000 CFU/mL in 20 (39.2 per cent) of milk samples. Its mean value was 4.8 log10 CFU/mL. The mean values of Enterobacteriaceae, psychrotrophic microorganisms, lipolytes, proteolytes, yeasts and moulds together, coagulase-positive staphylococci and somatic cell count were 3.3 log10 CFU/mL, 4.1 log10 CFU/mL, 3.2 log10 CFU/mL, 3.9 log10 CFU/mL, 2.2 log10 CFU/mL, 2.8 log10 CFU/mL and 5.3 log10 cells/mL, respectively. E. coli was found in 33.3 per cent of milk samples, while Listeria monocytogenes and antibiotics were not detected. The inner surface contamination of the dispensing nozzles and chambers was estimated in the range from 1.8 log10 CFU to 6.0 log10 CFU/cm2. The presence of detergents and disinfectants in supply valve eluates was determined in more than one-third of the samples. The hygienic-technical conditions of observed VM show some deviations from specified hygienic-technical requirements which could influence the safety of raw milk. Research limitations/implications The data about construction and the cleaning practice of VM, included in the experiment, were not available during the inspection facility. Originality/value In the paper the pathogenic and also the spoilage microorganisms in milk in the combination with hygienic conditions of inside surfaces of VM were studied.
