Air Quality and Employee Hygiene-related Behavior in a Post Anesthesia Care Unit in Thailand
Authors: Kampan Somphorn 
Published: April 2019

Background:Airborne contaminants in Postanesthesia Care Units (PACUs) such as bacteria, fungi, and waste anesthetic gases pose serious, and sometimes fatal, risks to both patients and PACU workers. Numerous studies have linked long-term exposure to nitrous oxide and halogenated agents to, among other things, reproductive problems in PACU nurses and anesthesiologists. Microorganism contamination can result in a post-surgical complication, to which patients with diabetes and other respiratory diseases are especially vulnerable. Various researchers and governmental agencies have recommended hospitals take steps to reduce levels of airborne contaminants in PACUs. In particular, hazard communication programs are recommended to inform and train staff on relevant occupational health and safety procedures. Additionally, and perhaps more importantly, experts recommend hospitals install specialized ventilation systems to maintain low levels of airborne pollutants.Objective:This study has two main parts: (1) measurement of airborne contaminants in the PACU at Rajavithi Hospital in Bangkok, Thailand; and (2) assessment of PACU workers’ perceived level of importance regarding occupational health and safety protocols,viaself-reporting survey. The study also has two main objectives: (1) to determine whether, and to what extent, a new ventilation system helps reduce airborne contaminants in the PACU; and (2) to discover whether an informational campaign increases perceived importance of health and safety procedures among PACU workers (i.e. handwashing, changing shoes, wearing proper facemasks).Methods:Surveys and air quality measurements were collected two times – in July 2016 and April 2017 – before and after Rajavithi Hospital implemented a hazard communication program consisting of training, posters, brochures, and informational media. Survey participants included all 64 PACU workers – 61 nurses and 3 anesthetists. Air sampling measured levels of bacteria, fungi, nitrous oxide, and desflurane.Results:Initial levels of airborne microorganisms were very high (1307CFU/m3for bacteria and 70.4 CFU/m3for fungi) and on the high end of normal for nitrous oxide (21.86ppm). Following the informational campaign and installation of the ventilation system, levels of bacterial contamination fell to 182 CFU/m3, and fungi fell to 35.8 CFU/m3. Simultaneously, workers’ levels of perceived importance for health and safety procedures increased.Conclusion:Both aspects of the study were successful, however, concentration of airborne microorganisms still exceeded recommended limits at the end of the study. Hospital administration and staff are encouraged to continue training and informing workers while assessing ventilation system until contamination levels fall to within internationally acceptable ranges.
Self-defining Memories in Normal Aging
Authors: El Haj Mohamad , Gallouj Karim 
Published: April 2019

Background:Self-defining memories refer to events that are vivid, effectively intense, and include enduring concerns about oneself.Objective:We investigated the relationship between the production of these memories in normal aging and the ability to integrate new information into existing knowledge in memory (i.e., updating).Method:Older participants were asked to perform an updating task as well as to retrieve autobiographical memories that were later analyzed for their self-defining relevance.Results:Analyses showed significant positive correlations between updating and the production of self-defining memories.Conclusion:Updating our life story is an important psychological process,which enables us to refine and enrich our life story with new experiences, roles and/or challenges, and this ability seems to be related to the capacity to produce memories that draw on the pursuit of long-term goals, meaning making, emotional regulation, and/or activation of self-images (i.e., self-defining memories). These findings suggest that updating one’s identity throughout life, at least in normal aging, may be related to the shaping and retrieval of self-defining memories, memories that lead to the creation of narrative scripts, which themselves serve as the ingredients for “chapters” across the lifespan.

Reflexões sobre o transe ritualístico no candomblé
Authors: Costa Alexandre , Moraes Junior Mário Pires de 
Published: April 2019

A manifestação corpórea de energias, ou espíritos, embora seja de ordem fenomenológica, constitui um importante viés de investigação no que tange a organização social de determinados grupos religiosos. Este trabalho tece algumas observações sobre o transe mediúnico no Candomblé de Ketu com base nas considerações de Roger Bastide, Reginaldo Prandi e na observação empírica. Seus dados provêm também de pesquisa etnográfica em terreiros de Candomblé de Goiânia e Região Metropolitana coordenado pelo Centro Integrado de Estudos África-Américas (CieeA – UEG) e Núcleo de Estudos Críticos e Aplicados ao Discurso Religioso (NOUS – UFG). A perspectiva transdiciplinar deste estudo pretende compreender nosso objeto não apenas com sua descrição, mas a partir de sua construção discursiva: ele é o que se diz sobre ele. Para tanto, articulamos com a leitura clássica dos estudos africanistas alguns conceitos de Focault e Bakhtin, tomando os documentos antropológicos e as falas coletadas como um conjunto de enunciados que se relacionam entre si, na rede de seus sujeitos e campos de saber.

Published: April 2019

Neste artigo, apresentamos uma discussão sobre a utilização de conceitos na construção de uma tese. Argumentamos a respeito da necessidade de entrar em contato com aquilo que não se faz tão evidente no processo do pensamento e, para tanto, afirmamos a necessidade de problematizar os conceitos numa operação que chamamos de desmontagem. Elencamos então algumas operações envolvidas nesse processo, inspiradas por Deleuze e Guattari, tomando como ponto de partida os conceitos como contingentes e construídos, situando-os no plano de imanência, historicizando-os e articulando-os com o campo problemático em que se constroem. Afirmamos, assim, o caráter criativo da construção de uma tese, na qual desmontar torna-se também remontar conceitos, dando consistência ao processo de produção de conhecimento.

Published: April 2019

Many of the world's political analysts who have contributed to the theory and study of contradictions and crises, they agree that today, unlike the past, the main sources of conflicts and crises on the global level are not the economy. But the main source of challenges and contradictions is ethnic, cultural conflict and many of the countries that were born in the past with a painful process of nation-building. Now they have been questioned as a national unit, and the moves of ethnicity and separatism have absorbed them.
Purpose: Attention to traditional and ethnic structures and the entry and presence of the government in the field of policy and political management of tribal diversity in Iran, which has been followed up by regulating ethnicity, state, and supervision of the movements of the ethnic groups (Jenkins, Richard, 1997).
Method: The practices and methods and rules have been examined by governments and regulating their interactions and relations with their relatives and their management and policy. As a result, Iran is described as a tumultuous society in which various ethnic and tribal groups have been in constant conflict with the state and with each other.

Authors: Bersezio C , Estay J , Sáez M , Sánchez F , Vernal R , Fernández E 
Published: April 2019

SUMMARY

Objectives:
It has been reported that bleaching generates an increase in the activity of osteoclasts in vitro. We quantified the RANK-L and IL-1β biomarkers in a double-blind, randomized clinical trial evaluating the in vivo effect of hydrogen peroxide (35%) and peroxide carbamide (37%) six months after whitening.

Methods and Materials:
Fifty volunteers participated, each with color change in a nonvital tooth. Fifty teeth were randomly divided into two groups (n=25), and the teeth were bleached using either 35% hydrogen peroxide (G1) or 37% carbamide peroxide (G2). Intracoronal bleaching was carried out by a technical “walking bleach” over four sessions. Gingival crevicular fluid samples were collected and used to quantify the IL-1β and RANK-L secreted levels. Samples of six periodontal sites (three vestibular and three palatal) were collected for up to six months (at the beginning of the study [baseline] and at one week, one month, and six months posttreatment). The color change was visually monitored using the Vita Bleached Guide (ΔSGU).

Results:
Comparing each time to baseline assessment, a significant increase in the levels of IL-1β and RANK-L across time points was detected (p&lt;0.05). The color change was 4 in G1 and G2, and a statistically significant difference (p&lt;0.05) was found at the month time point between the groups. Using the Spearman test, a strong correlation (&gt;0.8) between the IL-1β and RANK-L levels in both groups at all time points was detected.

Conclusions:
Nonvital bleaching using a technical walking bleach induces an increase in the IL-1β and RANKL production in periodontal tissues, which persists for six months after treatment. Both biomarkers were highly correlated in both groups and at all time points.

Authors: Wohlrab T , Flechtenmacher S , Krisam J , Saure D , Wolff D , Frese C 
Published: April 2019

SUMMARYObjectives:The aim of this trial was to investigate the diagnostic value of the basic erosive wear examination (BEWE) in clinical use, on dental photographs, and on dental casts over a two-year follow-up period (2013-2015). According to the main hypothesis for longitudinal monitoring of dental erosion, the BEWE is equally reproducible by the three assessment methods.Methods and Materials:The clinical assessment included intraoral photographic documentation, dental impressions, oral examination, and assessment of BEWE. Clinical assessment of BEWE was done by one blinded examiner, whereas assessment on photographs and dental casts was performed by three calibrated examiners and repeated after 14 days. The three assessment methods were analyzed separately by longitudinal agreement and inter- and intrarater reliability (intraclass correlation coefficient) alongside 95% confidence intervals (CIs).Results:Comparing the longitudinal data of the years 2013-2015, clinical use and photographs showed no significant difference (p=0.0681-0.9963), whereas the statistical analysis showed a significant difference for dental casts by comparing data from 2013 vs 2014 (p=0.0266) as well as data from 2013 vs 2015 (p=0.0001). Statistical evaluation of overall BEWE showed an intrarater reliability of 0.79-0.91 for photographs and 0.60-0.87 for dental casts. The interrater reliability was 0.77 (95% CI=[0.69; 0.84]) for photographs and 0.63 (95% CI=[0.52; 0.72]) for dental casts.Conclusion:This investigation showed that in longitudinal clinical monitoring, the assessment of the BEWE on patients and dental photographs yielded comparable results. In addition, based on these findings, the assessment of the BEWE on dental casts showed moderate reproducibility. Therefore, dental casts may be better used for laboratory assessment techniques.
Understanding Tire Dynamic Characteristics for Vehicle Dynamics Ride Using Simulation Methods
Authors: Siramdasu Yaswanth , Li Kejing , Wheeler Robert 
Published: April 2019

ABSTRACT
The dynamic characteristics of a tire are studied by simulating its rolling over a cleat and observing the effect on in-plane rigid belt vibration modes. Three modeling approaches are used to understand various tire design parameters affecting the tire dynamics relevant for vehicle ride performance. First, a simplified three-degree-of-freedom rigid ring model is used for fundamental understanding of these modes. Next, a detailed finite element model accounting for component compliances is used for studying the sensitivity of the modes to most common design parameter variations employed in tire development. Finally, to study these tire design changes in operation, vehicle simulations using CarSim and FTire models are performed. FTire model parameters corresponding to tire design parameters are adjusted accordingly. Observations are reported of the effects of tire design parameters on cleat responses and on correlation of results between finite element and FTire models.

HARDENING PRETREATMENT BY DROUGHT AND LOW TEMPERATURE ENHANCED CHILLING STRESS TOLERANCE OF CUCUMBER SEEDLINGS
Authors: Ghanbari Fardin , Kordi Sajad 
Published: April 2019

Chilling stress is of major limiting factors influencing the growth and development of warm-season crops like cucumber. In this research, the possibility of chilling tolerance of cucumber seedlings was investigated through employing the drought and low-temperature pretreatments. The factorial experiment consisted of two factors including cucumber cultivars (i.e. ‘Super Dominos’ and ‘Super Star’) and hardening treatments (control, low temperatures at 10°C, and 15°C and drought simulated by 10% and 20% PEG) based on completely randomized design (CRD) in 3 replications. After applying treatments and providing them 48 h opportunity to be recovered, the seedlings were subjected to 3°C for a six-day period and 6 h for each day. All hardening treatments improved seedlings’ growth, chlorophyll content, total phenol (TP) and antioxidant enzyme activities, while reducing chilling injury index and malondialdehyde (MDA) content. Comparing to temperature hardening, the drought pretreatment showed to have a better effect on inducing the chilling tolerance into cultivars. Overall, the results of this experiment showed that employing drought and low-temperature pretreatments enabled cucumber seedlings to mitigate the harmful effects of chilling.
