The study highlights the extension and scope of teachers’ work. Swedish teachers reflected on this before and after visiting schools in France, where “CPE-staff” alleviate teachers with different tasks. In sum, findings indicate that the extension and scope of teachers’ work can be discussed in terms of what, when and where, but also as already institutionalized or something that reshapes during negotiations on a daily basis. The findings are analyzed by the concepts of “structure” and “communitas” (Turner, 1974, 2008), highlighting how the professional boarders are dependent on patterns of structures and relationships within the school as an organization.

1 The described analytical procedure permits the simultaneous determination of the main n-hexane meta bolites in urine. 2-Hexanone, 2-hexanol, 2, 5-hexanediol and 2, 5-hexanedione, were chosen to dose the rats used in this study. All urine samples were collected and analysed on a daily basis, before and after acidic hydrolysis (pH 0.1) by GC/MS. 2-Hexanone, 2, 5-dimethylfurane, γ-valerolac tone and 2, 5-hexanedione were determined before hydro lysis ; 2-hexanol and 2, 5-hexanediol, after hydrolysis; and 5-hydroxy-2-hexanone and 4, 5-dihydroxy-2-hexanone were calculated by the difference between γ-valerolactone and 2, 5-hexanedione with and without hydrolysis, respectively. 2 A metabolic scheme was proposed reflecting the biotransformations undergone by the four compounds assayed. We consider 2, 5-dimethylfurane as a 'true metabolite' because the quantities detected were always greater before hydrolysis. 3 It has been reported that human and rat n-hexane metabolism follow a similar pattern. Therefore, as a practical application and without increasing either sample or time requirements, the simultaneous quantifi cation of the different metabolites and their excretion profile could provide better information about the metabolic situation of exposed workers than the determi nation of 2, 5-hexanedione alone. According to our experimental results, 4, 5-dihydroxy-2-hexanone itself would be a good toxicity indicator.

Microorganisms that have been identified in dental unit waterlines (DUWLs) are of concern because they can cause infections, especially in immunocompromised patients. This study aimed to assess the incidence of microbial contamination in DUWLs before and after intervention to reduce contamination, and to investigate the presence of coliforms, Escherichia coli and Pseudomonas aeruginosa. Water samples were collected aseptically from the waterlines. The high-speed hand-piece and dental chair units were served by one distillation apparatus, which was fed by the potable tap water of four dental clinics. Different interventions were used: chlorination, flushing before clinics and between patients, draining at the end of the day, and freshly distilled water on a daily basis. There was a significant difference between the level of contamination in the high-speed hand-piece (1.5–2.7 log CFU/ml) and dental chair unit water (2.0–3.5 log CFU/ml). Coliforms (0.9%) E. coli (0.9%) and Pseudomonas (1.8%) were detected during 2008. This study indicates the need to monitor water quality regularly and prevent stagnation in DUWLs to reduce the number of viable bacteria to <100 CFU/ml. We recommend flushing the DUWL for 2 min before the first patient and for 10–20 s between patients, flushing the dental unit at the end of the day and draining it overnight to reduce the development of biofilms, and chlorination of the DUWLs.

Reduced orthostatic tolerance (OT) is a serious concern facing space medicine. This work sought to evaluate the effects of intermittent hypoxic training (IHT) on OT in humans before and after 3 days of head-down bed rest (HDBR) used to model microgravity. The study was carried out in 16 male volunteers aged 18 to 40 years and included 2 series of experiments with 11-day and 21-day IHT administered on a daily basis. During the first IHT session, the concentration of oxygen in the inspired gas mixture was 10%; for other sessions it was adjusted to 9%. OT was assessed by a 20-minute-long orthostatic tilt test (OTT) conducted before and after HDBR. Before HDBR, orthostatic intolerance was observed in 3 participants, while after HDBR, it was observed in 9 of 16 volunteers (p < 0.05). During OTT conducted after HDBR, the heart rate (HR) exceeded control values by 26.8% (p < 0.01). Preexposure to any of the applied IHT regimens led to a reduction in the number of volunteers with orthostatic intolerance. After the 11-day IHT program, there was a less pronounced increase in HR during OTT before HDBR; with the extended IHT regimen, less pronounced changes were observed for HR, systolic, diastolic and mean blood pressure (BP). The increase in HR during OTT after HDBR was significantly lower in the group that had completed the 11-day IHT program, while BP remained stable. The changes in HR and systolic BP were less pronounced in the group that had completed the 21-day IHT program than in the control group (p < 0.05). Thus, IHT reduced the risk of orthostatic disorders and mitigated changes in cardiovascular parameters during the orthostatic test.

e16544 Background: It is known that abnormal expression of miRNAs in the gastric cancer (GC) contributes to its carcinogenesis. Therefore, ingestion of commercial (usual) water on a daily basis may be a contributing factor for the occurrence of alterations in the gastric mucosal. In this study, it was evaluated the expression of the miRNAs miR-29c, miR-7, miR-155, and miR-135b in the gastric tissue of patients with gastritis before and after the consumption of alkaline water (pH range from 8.0 to 10.0), as well as the clinic pathological characteristics. Methods: 50 subjects from the Amazon region, diagnosed with gastritis that routinely used commercial (usual) water with a pH lower than 5.0, were enrolled to change the consume water to a pH of 8.5 to 10.0 for 5 months. Results: Endoscopic findings of gastritis were such different (less severe disease), p = 0.024; in 43% diagnosed with moderate gastritis upfront esophagogastroduodenoscopy (EGD) presented mild gastritis after the consumption of alkaline water, according to study methods; there were no worsening gastritis and there were a significant increase in the expression of miR-135b (p = 0.039) and miR-29c (p = 0.039). Conclusions: Modified pH range water (from 8.0 to 10.0) ingested for 5 months was able lead to a less severe gastritis according to the Sidney classification system, suggesting that this lifestyle change represented a clinical benefit in patients with gastritis on the Amazon region. In addition, higher expression of miR-135b and miR-29c was observed after the consumption of alkaline water for 5 months. [Table: see text]

Extension agents are a valuable source of information within their communities throughout the world. Tasked with sharing research-based information from the universities and serving as the land-grant university within their communities, agents are the face and voice of the university on daily basis. However, this research sought to determine how confident new agents in Georgia were in their ability to effectively communicate within their communities before and after attending a communication workshop. Using a retrospective pre- and post-test survey, the results indicated the agents were most confident in their abilities create high-quality promotional videos and write Public Service Announcements for radio after the training. The results indicated agents were least confident in their abilities to utilize the Extension data base and write effectively. Overall, the results indicated in increase in agents’ perceived ability to effectively communicate in their communities after attending the training. Additionally, the results provide direction for future training and workshops to better prepare agents to effectively communicate information from land-grant universities to their communities and the world.

In modern society, stress reduction in the workplace is a pressing issue. Although many studies have been done on the psychological and physiological effects of indoor plants, the majority of them have been conducted in laboratory or quasi-office settings. The objective of this study was to verify the stress reduction effects of the presence of small indoor plants on employees in a real office setting. We investigated the changes in psychological and physiological stress before and after placing a plant on a worker’s desk. Sixty-three office workers at an electric company in Japan were the participants of this study. The participants were directed to take a 3-minute rest while sitting at their desk when they felt fatigue. There were two phases of the study: a control period without plants and an intervention period when the participants were able to see and care for a small plant. We measured psychological stress in the participants using the State-Trait Anxiety Inventory (STAI). As an index of physiological stress, the participants measured their own pulse rate throughout the study. STAI scores decreased significantly after the intervention period (P < 0.05). The ratio of the participants whose pulse rate lowered significantly after a 3-minute rest increased significantly during the intervention period (P < 0.05). Our study indicates that having opportunities to gaze intentionally at nearby plants on a daily basis in the work environment can reduce the psychological and physiological stress of office workers.

This chapter examines the idea of animals having humane jobs. The concept of humane jobs has been proposed primarily to help conceptualize and propel good work for people which also benefits animals. Here the focus expands to interrogate whether animals can be engaged in what could be considered humane jobs and what that would involve. By building in particular on feminist political economy and care ethics, as well as the front-line efforts of people who work with animals, the chapter elucidates key preconditions and perameters for certain animals to have humane jobs, including important inclusions and exclusions. Moreover, it argues that humane jobs are not sufficient on their own, but rather that we also ought to be emphasizing animals’ work-lives. This means understanding animals not only as workers but as whole beings, and taking seriously their lives, relationships, and experiences, before and after work, on a daily basis, and over their lifetimes. The chapter is thus both inductive and generative, and offers a constellation of ethical and conceptual considerations, intended to drive further research, foster nuanced and contextualized analysis, and help inspire tangible changes in thought and political action.

Aim. Up to 10 % of population suffer from asthma. Asthma often means managing a treatment with limited action on a daily basis. The study aim was to assess the impact of a General Osteopathic treatment (GOT) on the respiratory function in asthmatic children.Method. 15 asthmatic subjects, aged 4 to 15, diagnosed by an allergologist, received one GOT session. Objective results were obtained through a bodyplethysmography measure before and after treatment. Variables observed were: Tiffeneau′s coefficient, mean expiratory fl ow from small bronchial tubes, bronchial resistances and residual capacity.Results. Comparison between result before and after treatment showed a significant improvement of all measures after the GOT.Conclusions. On a short term basis, a session of GOT allows to asthmatic child to improve its lung capacity. Including Osteopathy in the pluridisciplinary care of asthmatic children appears to be relevant.

In land-based wastewater treatment systems, soil denitrification can remove sufficient added nitrogen to decrease leaching and the threat of water pollution. To establish a suitable sampling strategy for measuring in situdenitrification rates, we investigated the importance of spatial and temporal variability of denitrification in a forest soil regularly irrigated with wastewater. To determine appropriate sampling depths and locations in a catchment, denitrifying enzyme activity (DEA) was measured at 5 sampling depths (litter, 0-5, 5-10, 10-20, 20-40 cm), and 3 topographic positions (ridge, midslope, toeslope) in irrigated and nonirrigated sites. To determine appropriate times for sampling after irrigation, in situ denitrification rates were measured at time intervals before and after irrigation for 1 week, using soil cores and acetylene inhibition. DEA was greatest in the litter layer and decreased with depth. In irrigated soils, DEA was greater than zero in the upper 20 cm of toeslopes, and the upper 10 cm of midslopes and ridge positions. In situ denitrification rates increased immediately after wastewater irrigation, peaking at 24 h, and then decreased to pre-irrigation rates after 3 days, unless it rained. We concluded that soil cores need to be collected from at least the upper 10 cm soil (including the litter layer), and on a daily basis between irrigation events, to quantify denitrification losses from soil regularly irrigated with wastewater.
