    A system is provided to control the environment experienced by a child in a child safety seat. Each of a plurality of thermoelectric elements is individually controllable to be one of heated and cooled relative to an ambient temperature. A first portion of the thermoelectric elements are positioned on the child safety seat such that a child sitting therein is positioned thereover. A ventilator coupled to the child safety seat moves air past a second portion of the thermoelectric elements and filters the air moved therepast. One or more jets coupled to the ventilator receive the filtered air. Each jet is coupled to the child safety seat and can be positioned to direct the heated/cooled filtered air to the vicinity of the head of the child sitting in the child safety seat.

    Despite the strong evidence of child safety seats (CSSs) effectiveness in reducing injuries, it is still rarely used in some societies. The purpose of this study was to determine prevalence and predictors of CSS use in Mashad, Iran. Five hundred ninety kindergarten children whose parents owned a car were enrolled in the study. Parents were asked about using CSS for their children, reasons for CSS use/non-use, demographics, history of road traffic injuries and receiving any advice on CSS. Of families, 25.5% expressed that they used CSS for their child at present or any time in the past, but only 6.3% of children travelled restrained in CSS at the time of study. Age-appropriate CSS use was reported in 14.5% of infants and 2.3% of 1-5-year-old children. A significant relationship was observed between lower child age, higher maternal education and high family income with CSS use. The main reasons for CSS none-use were reported as not feeling the need (42%), followed by its high price (22%). Use of CSS was uncommon. The financial concerns and information gap about the essential need for CSS should be considered as priorities for action especially among lower socio-economic groups of society. PMID:25077890

  8. Boosting safety behaviour: Descriptive norms encourage child booster seat usage amongst low involvement parents.

    2016-07-01

    Campaigns advocating behavioural changes often employ social norms as a motivating technique, favouring injunctive norms (what is typically approved or disapproved) over descriptive norms (what is typically done). Here, we investigate an upside to including descriptive norms in health and safety appeals. Because descriptive norms are easy to process and understand, they should provide a heuristic to guide behaviour in those individuals who lack the interest or motivation to reflect on the advocated behaviour more deeply. When those descriptive norms are positive - suggesting that what is done is consistent with what ought to be done - including them in campaigns should be particularly beneficial at influencing this low-involvement segment. We test this proposition via research examining booster seat use amongst parents with children of booster seat age, and find that incorporating positive descriptive norms into a related campaign is particularly impactful for parents who report low involvement in the topic of booster seat safety. Descriptive norms are easy to state and easy to understand, and our research suggests that these norms resonate with low involvement individuals. As a result, we recommend incorporating descriptive norms when possible into health and safety campaigns. PMID:27085145

  11. Biomechanical analysis of padding in child seats and head injury.

    Science.gov (United States)

    Kumaresan, Srirangam; Sances, Anthony; Carlin, Fred

    2002-01-01

    Head injury is a common finding for infants and young children involved in automobile accidents. Although the child restraint seats have increased the level of safety for the pediatric population, skull fracture and/or brain injury occur during the interaction between the child's head and interior of the car seats with no padding. The introduction of effective and sufficient padding may significantly reduce the head injury. The present study was designed to evaluate the biomechanical effects of padding in child seats to reduce the potential for head injury. A head drop test of a six-month old anthropomorphic dummy was conducted. The side of the dummy head impacted the interior wing of child car seats of relatively soft and stiff materials, and a rigid metal plate at velocities of 2.2, 4.5 and 6.7 m/s. In all tests, three types of padding environments were used (no padding, comfort foam, 16 to 19 mm polypropylene padding). All data were collected at 10 kHz and filtered. A total of 39 tests were conducted. The head injury criteria (HIC), and head acceleration, and head angular acceleration were obtained. The HIC was calculated over a 36 ms interval from the resultant tri-axial acceleration. The angular accelerations were derived from the angular velocity data. The head injury biomechanical parameters decreased with the addition of padding. The HIC, peak acceleration, and angular acceleration were reduced up to 91%, 80%, and 61% respectively. The present results emphasize the importance of energy absorbing padding to provide an improved safety environment in child car seats.

    The safest way for children to travel within a car is by provision of a weight-appropriate safety-seat. To investigate this, we conducted a cross-sectional study of adult parents who had children under 12 years, and collected information related to: car use, safety-seat legislation, and type of safety-seat employed. Data were reviewed on 120 children from 60 respondents. Ninety-eight (81.7%) children were transported daily by car. Forty-eight (81.4%) respondents were aware that current safety-seat legislation is based on the weight of the child. One hundred and seven (89.9%) children were restrained during travel using a car safety-seat. One hundred and two (96.2%) safety seats were newly purchased, installed in 82.3% (88) cases by family members with installation instructions fully read in 58 (55.2%) cases. Ninety-nine (83.2%) children were restrained using an appropriate safety-seat for their weight. The results show that four out of five families are employing the most appropriate safety-seat for their child, so providing an effective mechanism to reduce car-related injury. However, the majority of safety-seats are installed by family members, which may have child safety consequences.

  14. Advanced Infant Car Seat Would Increase Highway Safety

    Science.gov (United States)

    Dabney, Richard; Elrod, Susan

    2004-01-01

    An advanced infant car seat has been proposed to increase highway safety by reducing the incidence of crying, fussy behavior, and other child-related distractions that divert an adult driver s attention from driving. In addition to a conventional infant car seat with safety restraints, the proposed advanced infant car seat would include a number of components and subsystems that would function together as a comprehensive infant-care system that would keep its occupant safe, comfortable, and entertained, and would enable the driver to monitor the baby without having to either stop the car or turn around to face the infant during driving. The system would include a vibrator with bulb switch to operate; the switch would double as a squeeze toy that would make its own specific sound. A music subsystem would include loudspeakers built into the seat plus digital and analog circuitry that would utilize plug-in memory modules to synthesize music or a variety of other sounds. The music subsystem would include a built-in sound generator that could synthesize white noise or a human heartbeat to calm the baby to sleep. A second bulb switch could be used to control the music subsystem and would double as a squeeze toy that would make a distinct sound. An anti-noise sound-suppression system would isolate the baby from potentially disturbing ambient external noises. This subsystem would include small microphones, placed near the baby s ears, to detect ambient noise. The outputs of the microphone would be amplified and fed to the loudspeakers at appropriate amplitude and in a phase opposite that of the detected ambient noise, such that the net ambient sound arriving at the baby s ears would be almost completely cancelled. A video-camera subsystem would enable the driver to monitor the baby visually while continuing to face forward. One or more portable miniature video cameras could be embedded in the side of the infant car seat (see figure) or in a flip-down handle. The outputs of

    Child safety restraints can reduce risk of death and decrease injury severity from road traffic crashes; however, knowledge about restraints and their use in Kuwait is limited. A cross-sectional, self-administered survey about child car safety was used among a convenience sample of parents of children aged 18 years or younger at five Kuwaiti university campuses. Of 552 respondents, over 44% have seated a child in the front seat and 41.5% have seated a child in their lap while driving. Few parents are aware of and fewer report using the appropriate child restraint; e.g., 36% of parents of infants recognised an infant seat and 26% reported using one. Over 70% reported wearing seat belts either "all of the time" (33%) or "most of the time" (41%). This new information about parents' knowledge and practice regarding child car seat use in Kuwait can inform interventions to prevent child occupant injury and death.

    Despite significant reductions in the number of children killed in motor vehicle crashes over the past decade, crashes continue to be the leading cause of death for children 4 years and older. Therefore, the American Academy of Pediatrics continues to recommend inclusion of child passenger safety anticipatory guidance at every health-supervision visit. This technical report provides a summary of the evidence in support of 5 recommendations for best practices to optimize safety in passenger vehicles for children from birth through adolescence that all pediatricians should know and promote in their routine practice. These recommendations are presented in the revised policy statement on child passenger safety in the form of an algorithm that is intended to facilitate their implementation by pediatricians with their patients and families. The algorithm is designed to cover the majority of situations that pediatricians will encounter in practice. In addition, a summary of evidence on a number of additional issues that affect the safety of children in motor vehicles, including the proper use and installation of child restraints, exposure to air bags, travel in pickup trucks, children left in or around vehicles, and the importance of restraint laws, is provided. Finally, this technical report provides pediatricians with a number of resources for additional information to use when providing anticipatory guidance to families. PMID:21422094

  7. Seating Considerations for Spaceflight: The Human to Machine Interface

    Science.gov (United States)

    Gohmert, Dustin M.

    2011-01-01

    Seating is one of the most critical components to be considered during design of a spacecraft. Since seats are the final interface between the occupant and the vehicle wherein all launch and landing operations are performed, significant effort must be spent to ensure proper integration of the human to the spacecraft. The importance of seating can be divided into two categories: seat layout and seat design. The layout of the seats drives the overall cabin configuration - from displays and controls, to windows, to stowage, to egress paths. Since the layout of the seats is such a critical design parameter within the crew compartment, it is one of the first design challenges that must be completed in the critical path of the spacecraft design. In consideration of seat layout in the vehicle, it is important for the designers to account for often intangible factors such as safety, operability, contingency performance, crew rescue. Seat layout will lead to definition of the quantity, shape, and posture of the seats. The seats of the craft must restrain and protect the occupant in all seated phases of flight, while allowing for nominal mission performance. In design of a spacecraft seat, the general posture of the occupant and the landing loads to be encountered are the greatest drivers of overall design. Variances, such as upright versus recumbent postures will dictate fit of the seat to the occupant and drive the total envelope of the seat around the occupant. Seat design revolves around applying sound principles of seated occupant protection coupled with the unique environments driven by the seat layout, landing loads, and operational and emergency scenarios.

    Roadway incidents involving motorized vehicles accounted for 24% of fatal occupational injuries in the United States during 2013 and were the leading cause of fatal injuries among workers.* In 2013, workers' compensation costs for serious, nonfatal injuries among work-related roadway incidents involving motorized land vehicles were estimated at $2.96 billion.(†) Seat belt use is a proven method to reduce injuries to motor vehicle occupants (1). Use of lap/shoulder seat belts reduces the risk for fatal injuries to front seat occupants of cars by 45% and the risk to light truck occupants by 60%.(§) To characterize seat belt use among adult workers by occupational group, CDC analyzed data from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) and found that not always using a seat belt was significantly associated with occupational group after controlling for factors known to influence seat belt use. Occupational groups with the highest prevalences of not always using a seat belt included construction and extraction; farming, fishing, and forestry; and installation, maintenance, and repair. To increase seat belt use among persons currently employed, states can enact and enforce primary seat belt laws, employers can set and enforce safety policies requiring seat belt use by all vehicle occupants, and seat belt safety advocates can target interventions to workers in occupational groups with lower reported seat belt use.

  15. Child pedestrian safety: parental supervision, modeling behaviors, and beliefs about child pedestrian competence.

    Science.gov (United States)

    Morrongiello, Barbara A; Barton, Benjamin K

    2009-09-01

    Pedestrian injuries are a significant health risk to children, particularly those 5-9 years of age. Surprisingly, few studies have explored parent-related factors that may moderate this risk. The present study used naturalistic observations of parent-child pairs crossing at uncontrolled intersections and a short interview to examine parental supervision of children during crossings, modeling of safe-crossing behaviors, beliefs about how children come to cross streets safely, and whether child attributes (age, sex) relate to parental practices and beliefs. Results revealed that parents more closely supervised younger than older children, they modeled safer crossing practices for sons more than daughters, particularly younger sons, and although over half the sample believed children need to be explicitly taught how to cross safely, few actually provided any instruction when crossing with their children. Providing parents both with guidelines for how to accurately appraise their child's readiness for crossing independently and with information about best practices for teaching children how to cross safely may facilitate parents' implementing these practices, particularly if this is coupled with public advocacy highlighting the important role they could play to reduce the risk of child pedestrian injury.

  16. Seating arrangement in Althingi

    Directory of Open Access Journals (Sweden)

    Þorsteinn Magnússon

    2014-12-01

    Full Text Available Almost a century has passed since Althingi, the Parliament of Iceland, introduced, in 1916, the method of allocating seats to Members by drawing lots at the start of each session. This arrangement is not customary in any other national parliament in the world. It has never been established why this particular method of allocating seats was introduced in Althingi. Neither has it been mapped out how the allocation was conducted, what the Members thought of it nor what impact, if any, the arrangement had on the relations of Members and the workings of Althingi. This article therefore presents the first study of this subject in Iceland. The article also places the seat allocation procedure of Althingi in an international context, as the general rule in parliaments around the world is that Members are seated together in parliamentary party groups. The conclusions of the study are, among other things, that the seat allocation by lot was probably modelled on the House of Representatives of the United States Congress, where seats were allocated by lot from 1845-1913. The study also reveals that over 40 years passed until seat allocation by lot became fully established procedure in Althingi. In the Upper House seats were not allocated by lot at the great majority of sessions until 1959 and Members appear to have been mainly seated along party lines. In the Lower House it was common for some Members to exchange seats following the drawing of lots, and for some time attempts were made to introduce seating by parliamentary party, but the efforts were unsuccessful due to insufficient support. Since 1959 there has not been any disagreement regarding the drawing of lots for seats. Generally speaking, Members appear to hold the opinion that the seating arrangement in Althingi has a positive impact on personal relations, is a positive counterbalance to the division of Members into government supporters and opposition members and that the allocation of seats by

    Most studies of postural hypotension (PH) have focused on standing PH. Less is known about PH after transition from a supine to sitting position. Moreover, seated PH has not been previously reviewed in the English literature. The aim of this review was to provide current information regarding seating-induced PH. Seventeen studies were reviewed regarding prevalence, methods of evaluation, manifestations, predisposing factors, prognosis, and management of seated PH. Prevalence ranged from 8% among community-dwelling persons to 56% in elderly hospitalized patients. Dizziness and palpitations were the most frequent symptoms. Of a variety of factors that have been identified as predisposing and contributing to seated PH, aging, bed rest, and hypertension were most important. Because seated PH is a common, easily diagnosable and frequently symptomatic condition, especially in elderly inpatients, this disorder warrants attention. Moreover, seating-induced falls in blood pressure and the associated symptoms, may be largely prevented by nonpharmacologic interventions. PMID:26515671

    1989-11-01

    The Albuquerque Operations Office through the Pinellas Plant Area Office is involved in a joint venture to establish a Partnership School and a Day Care Facility at the Plant. The venture is unique in that it is based on a partnership with the local county school system. The county school system will provide the teachers, supplies and classroom furnishings for the operation of the school for pre-kindergarten, kindergarten, first and second grade during regular school hours. The Government will provide the facility and its normal operating and maintenance costs. A Day Care Facility will also be available for children from infancy through the second grade for outside school hours. The day care will be operated as a non-profit corporation. Fees paid by parents with children in the day care center will cove the cost of staff, food, supplies and liability insurance. Again, the government will provide the facility and its normal operating and maintenance costs. Between 75 and 90 children are expected in the first year of operation. The Partnership School will consist of one class each for pre-kindergarten, kindergarten and first grade. Second grade will be added in 1990. The total estimated number of children for both the Child Care and Partnership School should not exceed 200 children. Expected benefits include reduced absenteeism, tardiness and turnover and thus increased productivity. The program will be an asset in recruiting and retaining the best workforce. Other benefits include improved education for the children.

  19. Poor compliance with child safety restraint use while travelling.

    LENUS (Irish Health Repository)

    Fallon, R

    2011-02-01

    Road traffic accidents are a leading cause of death of children. It is the law that all children should be appropriately secured when traveling in vehicles. The aim of this study was to evaluate parental conformity with these regulations and to test if advice given at a Paediatric outpatient clinic could improve compliance. Two groups were assigned, an intervention group (parents given an information leaflet and a clear explanation about appropriate restraints for their children) and a non-intervention group (received no information). They were contacted again after 2 months and asked regarding compliance. A total of 394 children from 186 families were initially given the questionnaire. Nearly one third of children (29.2%) were not using any restraint while travelling rising to 35.3% on follow up. This study concluded that once off parental education made negligible difference to an already inconsistent and haphazard approach to compliance with safety regulations.

    2007-01-01

    This paper presents a system to alert of dangerous a child situation of a child by applying context information collected from a home network to ontology that is capable of inference. Radio frequency Identification (RFID) and sensors were used for the configuration of a home network, to obtain the raw data to convert into context information. To express the ontology, web ontology language (OWL) was used to provide the inference of context information. Then, simple object access protocol (SOAP) messages were used to notify of the dangerous situations that a child may be involved in via mobile devices. The proposed system consists of Context Manager, Service Manager, and Notification Manager. The child's safety management system can proactively detect the context data of a child on the basis of context awareness. In the experiment, the Jena 2.0 by ontology reasoner and the OSGi(Open Service Gateway initiative) Gateway developed using open source software Knopflerfish 1.3.3 were used to implement the service frame work.

  4. Social protection for all ages? Impacts of Ethiopia's Productive Safety Net Program on child nutrition.

    Porter, Catherine; Goyal, Radhika

    2016-06-01

    We investigate the impact of a large-scale social protection scheme, the Productive Safety Net Program (PSNP) in Ethiopia, on child nutritional outcomes. Children living in households that receive cash transfers should experience improved child nutrition. However, in the case of the PSNP, which for the majority of participants is a public works program, there are several potential threats to finding effects: first, without conditionality on child inputs, increased household income may not be translated into improved child nutrition. Second, the work requirement may impact on parental time, child time use and calories burned. Third, if there is a critical period for child human capital investment that closes before the age of 5 then children above this age may not see any improvement in medium-term nutritional outcomes, measured here as height-for-age. Using a cohort study that collected data both pre-and post-program implementation in 2002, 2006 and 2009, we exploit several novel aspects of the survey design to find estimates that can deal with non-random program placement. We present both matching and difference-in-differences estimates for the index children, as well as sibling-differences. Our estimates show an important positive medium-term nutritional impact of the program for children aged 5-15 that are comparable in size to Conditional Cash Transfer program impacts for much younger children. We show indicative evidence that the program impact on improved nutrition is associated with improved food security and reduced child working hours. Our robustness checks restrict the comparison group, by including only households who were shortlisted, but never received PSNP, and also exclude those who never received aid, thus identifying impact based on timing alone. We cannot rule out that the nutritional impact of the program is the same for younger and older children. PMID:27176466

    Unintentional injury is a leading cause of death worldwide, and the number one cause of child death in the United States. The American Academy of Pediatrics promotes safety recommendations to decrease child injury risk, however the majority of educational programs delivering these strategies are school-based or in community campaigns. Mobile technology provides an opportune platform to deliver pediatric injury prevention programs given its massive global reach and underrepresentation within the current mobile health market. This paper describes the development of iBsafe, a novel mobile safety game application designed to prevent injury in 5- to 6- year old children. Our multidisciplinary team utilized a step-wise approach to create an innovative child game application which is based in behavioral theory and promotes evidence-based safety recommendations. Results and future directions for iBsafe aim to interactively educate children on how to be safe and ultimately improve their safety behaviors.

    An outcome analysis was conducted based on an extended follow-up of the implementation of differential response program reforms in Child Protective Services offices in 10 counties in a Midwestern U.S. State. Random assignment was conducted of families that were first determined to be appropriate for family assessments. Experimental families (n=2,382) were each assigned to a non-forensic family assessment, and control families (n=2,247) each received a forensic investigation. Families were assigned continuously over a 15-month period and then tracked from 45 to 60 months from the date of assignment. Detailed information on services provided and family responses was obtained via two subsamples of experimental and control families. Measures of family engagement and service reception and utilization were utilized to determine instrumental outcomes introduced through family assessments. Improved family engagement and increased and broadened services were found to have occurred, and it was theorized that these changes mediated extended outcomes. Extended outcomes included reductions of rates of subsequent screened-in reports of child maltreatment, proportions of families that experienced child removals, and instances of new safety threats and problems in parenting. Differences in outcomes were found among the participating counties with 4 counties accounting for most outcome differences. The relationships between instrumental and extended outcomes were discussed with suggestions for further research. PMID:24957562

  8. Drug monitoring in child and adolescent psychiatry for improved efficacy and safety of psychopharmacotherapy

    Directory of Open Access Journals (Sweden)

    Fegert Jörg M

    2009-04-01

    Full Text Available Abstract Most psychotropic drugs used in the treatment of children and adolescents are applied "off label" with a direct risk of under- or overdosing and a delayed risk of long-term side effects. The selection of doses in paediatric psychiatric patients requires a consideration of pharmacokinetic parameters and the development of central nervous system, and warrants specific studies in children and adolescents. Because these are lacking for most of the psychotropic drugs applied in the Child and Adolescent and Psychiatry, therapeutic drug monitoring (TDM is a valid tool to optimise pharmacotherapy and to enable to adjust the dosage of drugs according to the characteristics of the individual patient. Multi-centre TDM studies enable the identification of age- and development-dependent therapeutic ranges of blood concentrations and facilitate a highly qualified standardized documentation in the child and adolescent health care system. In addition, they will provide data for future research on psychopharmacological treatment in children and adolescents, as a baseline for example for clinically relevant interactions with various co-medications. Therefore, a German-Austrian-Swiss "Competence Network on Therapeutic Drug Monitoring in Child and Adolescent Psychiatry" was founded 1 introducing a comprehensive internet data base for the collection of demographic, safety and efficacy data as well as blood concentrations of psychotropic drugs in children and adolescents.

    Full Text Available The objective of this study was to assess the level of parental car safety knowledge and actual behavior regarding their children under the age of 15 years. This study forms part of the National Center for Child Safety and Health in Israel (Beterem program to examine awareness on child safety. Seven hundred and five Jewish families with at least one child at home younger than 15 years (a total of 1,345 children were used as a randomized sample of the Jewish population. A telephone survey was conducted by professional interviewers using a questionnaire developed by injury prevention specialists consisting of seven knowledge questions and a diagram that described the usual seating positions and restraining method of the family members in the family car. Concerning knowledge about injury prevention, the rate of incorrect answers was high,64% in regard to the proper car seats for age and 84% in regard to the age for booster seats. Sixty five per cent of parents did not know what a booster seat was and 54% did not know that the proper place for children was in the back seat. The average of incorrect answers was 4.86 out of 7 (SD=1.45 correlated with low socioeconomic status. Concerning care safety behavior 60% per cent of babies and 38% of toddlers were not restrained properly. This study should alert planners and policy makers to the need of implementation of educational prevention programs for the Israeli public of parents concerning car safety for children in order to reduce childhood injury.

    The development of more comfortable seats is an important issue in the automotive industry. However, the development of new car seats is very time consuming and costly since it is typically based on experimental evaluation using prototypes. Computer models of the human-seat interaction could accelerate this process. The objective of this paper is to establish a protocol for the development of seat models using numerically efficient simulation techniques. The methodology is based on multi-body techniques: arbitrary surfaces, providing an accurate surface description, are attached to rigid bodies. The bodies are connected by kinematic joints, representing the seat back recliner and head restraint joint. Properties of the seat foam and frame have been lumped together. Further, experiments have been defined to characterise the mechanical properties required for the seat model for comfort applications. The protocol has been exemplified using a standard car seat. The seat model has been validated based on experiments with rigid loading devices with human-like shapes in terms of force-deflection characteristics. The response of the seat model agrees well with the experimental results. Therefore the presented method can be a useful tool in the seat development process, especially in early stages of the design process.

    Full Text Available Abstract Background Domestic violence affects many women during their lifetime. Children living in homes where they are or have been exposed to violence are at increased risk for adverse outcomes. The American Academy of Pediatrics, the American Academy of Family Practice, and the American College of Obstetrics/Gynecology have recently joined in recommending routine screening of all families for the presence of domestic violence. We present our experience with an office-based domestic violence screening questionnaire. Methods A series of four child safety questionnaires (designed for parents of infant, preschool-age, school-age, and adolescent patients, which included specific questions about domestic violence, was given to all mothers presenting to a university out-patient general pediatric clinic. The questionnaires, offered in both English and Spanish, were reviewed for the presence of domestic violence exposure, usually at the time of the clinic visit. The number of women who reported either current or past exposure to domestic violence as disclosed by this active screening process was compared to the number discovered prior to the use of these questionnaires. Results Prior to the use of active screening with a child safety questionnaire, five cases of domestic violence were identified in our clinic population of approximately 5000 children over a 3 month period. Active screening of this population with a parent questionnaire resulted in the identification of 69 cases of current domestic violence exposure (2% of those screened during each of 2 years of screening. Use of the child safety questionnaire was associated with a significantly increased odds of detecting current domestic violence (OR = 3.6, 95% CI [1.4, 9.1], P = 0.007, with 72% [26–84%] of the cases identified being attributable to the use of the questionnaire. Of children screened, 2% were currently exposed to domestic violence, and 13% had been exposed to past domestic violence

    Full Text Available Abstract Background Injuries in or around the home are the most important cause of death among children aged 0-4 years old. It is also a major source of morbidity and loss of quality of life. In order to reduce the number of injuries, the Consumer Safety Institute introduced the use of Safety Information Leaflets in the Netherlands to provide safety education to parents of children aged 0-4 years. Despite current safety education, necessary safety behaviours are still not taken by a large number of parents, causing unnecessary risk of injury among young children. In an earlier study an E-health module with internet-based, tailored safety information was developed and applied. It concerns an advice for parents on safety behaviours in their homes regarding their child. The aim of this study is to evaluate the effect of this safety information combined with personal counselling on parents' child safety behaviours. Methods/Design Parents who are eligible for the regular well-child visit with their child at child age 5-8 months are invited to participate in this study. Participating parents are randomized into one of two groups: 1 internet-based, tailored safety information combined with personal counselling (intervention group, or 2 personal counselling using the Safety Information Leaflets of the Consumer Safety Institute in the Netherlands for children aged 12 to 24 months (control group. All parents receive safety information on safety topics regarding the prevention of falling, poisoning, drowning and burning. Parents of the intervention group will access the internet-based, tailored safety information module when their child is approximately 10 months old. After completion of the assessment questions, the program compiles a tailored safety advice. The parents are asked to devise and inscribe a personal implementation intention. During the next well-child visit, the Child Health Clinic professional will discuss this tailored safety information

  15. The Prediciton of Seat Transmissibility from Measures of Seat Impedance

    Wei, L.; Griffin, J.

    1998-07-01

    A method of predicting seat transmissibility from mathematical models of the seat and the human body is described. The complex dynamic stiffness of a seat is determined by measurement using an indenter rig, and its stiffness and damping subsequently determined by curve-fitting. By using the fitted stiffness and damping of the seat model, and a previously determined dynamic model of the human body, the seat transmissibility is predicted mathematically. The method is illustrated with data obtained with a car seat and also a rectangular sample of foam. The seat and foam transmissibilities were predicted over the frequency range 1·25-25 Hz using two alternative models of the human body (a one-degree-of-freedom model and a two-degree-of-freedom model). The predicted seat transmissibilities were close to those measured in a group of eight subjects over the entire frequency range. The two-degree-of-freedom model of the human body provided better predictions where the seat and foam showed a second resonance around 8 Hz. The need for a non-linear mathematical model of the human body and a non-linear seat model is discussed.

    Objective: Seat belt use during pregnancy reduces injury to the mother and her fetus. During recent years, the use of seat belts has been mandated by law in Iran. The purpose of this study was to determine the attitudes and practices of pregnant women regarding seat belt use.Methods: In this cross-sectional study, we asked 335 pregnant women at a hospital-based prenatal care clinic on the use of safety belt before and during pregnancy. SPSS version 13.0 was used for data analysis.Results: The mean age of study subjects was 27.3 years±5.3 years with the median of 27 years. Compared with the seat belt use before pregnancy, no change was detected in 48.7% of the women; seat belt use had increased in 17.5 %of them and decreased in 33.8 %. Eighty-one percent of women knew the correct placing of both lap belt and shoulder belt. Only 4% of women had received education on proper restraint use during pregnancy.Conclusions: The prevalence of seat belt use during pregnancy is lower than reports which are mostly from developed nations. The fact that about one-third of women have decreased their seat belt usage during pregnancy highlights the importance of education of mothers on this topic.

  18. Statistical Performance Evaluation Of Soft Seat Pressure Relief Valves

    2013-03-26

    Risk-based inspection methods enable estimation of the probability of failure on demand for spring-operated pressure relief valves at the United States Department of Energy's Savannah River Site in Aiken, South Carolina. This paper presents a statistical performance evaluation of soft seat spring operated pressure relief valves. These pressure relief valves are typically smaller and of lower cost than hard seat (metal to metal) pressure relief valves and can provide substantial cost savings in fluid service applications (air, gas, liquid, and steam) providing that probability of failure on demand (the probability that the pressure relief valve fails to perform its intended safety function during a potentially dangerous over pressurization) is at least as good as that for hard seat valves. The research in this paper shows that the proportion of soft seat spring operated pressure relief valves failing is the same or less than that of hard seat valves, and that for failed valves, soft seat valves typically have failure ratios of proof test pressure to set pressure less than that of hard seat valves.

    Full Text Available Today, intelligent safety systems are installed in modern cars in view of minimising road hazards. An intelligent air bag system for example, comprised several subsystems that are integrated to include the weight sensor system, image sensor system, crash sensor system and tyre pressure monitoring system. These systems when poorly positioned into the car seat, will certainly affect comfort and reliability of the car seat. This research presents the design work on an intelligent car seat, which is equipped with a load cell type-sensory system. The load cells are used to detect the weight of a passenger for the deployment of an air bag system. The proposed design is validated against displacement and stress analysis using an 80 kg load to simulate the weight of a passenger. Results from the design validation indicated that the proposed configuration and material is appropriate for use in the intelligent car seat application.

    Full Text Available Introduction. Motor vehicle crashes are the leading cause of death among US children aged 4–14 years. In theory, health provider counseling about Child Passenger Safety (CPS could be a useful deterrent. The data about the effectiveness of CPS dissemination is sparse, but existing results suggest that providers are not well informed. Moreover, there is insufficient evidence to determine whether provider counseling about CPS is effective. Methods. We therefore assessed CPS best practice knowledge among 217 healthcare workers at hospitals in seven cities throughout the USA and evaluated the impact of a brief, lunch and learn educational intervention with a five-item questionnaire. Attendees were comprised of physicians, nurses, social workers, pediatric residents, and pediatric trauma response teams. Results. Pre-post survey completion was nearly 100% (216 of 217 attendees. Participation was fairly evenly distributed according to age (18–29, 30–44, and 45+ years. More than 80% of attendees were women. Before intervention, only 4% of respondents (9/216 answered all five questions correctly; this rose to 77% (167/216 (P<0.001, using a Wilcoxon signed-rank test after intervention. Conclusion. Future research should consider implementation and controlled testing of comparable educational programs to determine if they improve dissemination of CPS best practice recommendations in the long term.

    Unintentional injury is the leading cause of death among children, with approximately 45% of injuries occurring in and around the home. Rates of home injury are particularly high in the homes of caregivers who are referred for intervention services by child welfare agents. However, there are few validated methods of home safety assessment available. The Home Safety and Beautification Assessment (HSBA) was developed to assist intervention planning specific to home safety and appearance in a sample of 77 mothers who were referred to treatment by Child Welfare Services. Exploratory factor analysis of HSBA items indicated that safety and appearance factors emerged across rooms in the home, and internal consistencies were good. For each room, the sums of assessors' safety and appearance intervention priority item scores were correlated with the assessors' global safety and appearance ratings of the entire home, respectively. The participants' overall room attractiveness scores were correlated with the assessors' overall room appearance intervention priority scores, whereas the participants' ratings of overall room safety were not correlated with the assessors' overall room safety intervention priority scores. Participants' scores on the Abuse subscale of the Child Abuse Potential Inventory, personal income, and education level were not associated with the assessors' home safety and appearance intervention priority ratings, suggesting the HSBA is assessing constructs that are distinct from child abuse potential and socioeconomic status. The results support the HSBA in a sample referred to treatment by child welfare agents. (PsycINFO Database Record PMID:26322799

Prior research has revealed that theatre patrons show a bias towards sitting on the right side of a movie theatre. Two competing theories have attempted to explain this seating asymmetry: one posits that expectation of processing demand drives the bias; the other posits that basic motor asymmetries drive the bias. To test these theories we assessed the real-world classroom seating choices of university students using photographs. A bias for students to choose seats on the left side of the classroom was observed, in contrast to the right side bias observed in theatre seating studies. These results provide evidence in support of a processing-expectation bias.

  7. The Effects of Microgravity on Seated Height (Spinal Elongation)

    Young, K. S.; Rajulu, S.

    2011-01-01

    ABSTRACT Many physiological factors, such as spinal elongation, fluid shifts, bone atrophy, and muscle loss, occur during an exposure to a microgravity environment. Spinal elongation is just one of the factors that can also affect the safety and performance of a crewmember while in space. Spinal elongation occurs due to the lack of gravity/compression on the spinal column. This allows for the straightening of the natural spinal curve. There is a possible fluid shift in the inter-vertebral disks that may also result in changes in height. This study aims at collecting the overall change in seated height for crewmembers exposed to a microgravity environment. During previous Programs, Apollo-Soyuz Test Project (ASTP) and Skylab, spinal elongation data was collected from a small number of subjects in a standing posture but were limited in scope. Data from these studies indicated a quick increase in stature during the first few days of weightlessness, after which stature growth reached a plateau resulting in up to a 3% increase of the original measurement [1-5]. However, this data was collected only for crewmembers in standing posture and not in a seated posture. Seated height may have a different effect than standing height due to a change in posture as well as due to a compounded effect of wearing restraints and a potential compression of the gluteal area. Seated height was deemed as a critical measurement in the design of the Constellation Program s (CxP) Crew Exploration Vehicle (CEV), called Orion which is now the point-of-departure vehicle for the Multi-Purpose Crew Vehicle (MPCV) Program; therefore a better understanding of the effects of microgravity on seated height is necessary. Potential changes in seated height that may not have impacted crew accommodation in previous Programs will have significant effects on crew accommodation due to the layout of seats in the Orion.. The current and existing configuration is such that the four crewmembers are stacked two by

  10. Optimization of Car Seats in the Interaction of Sitting Man on the Size of the Contact Pressure

    Science.gov (United States)

    Martonka, R.; Fliegel, V.

    The crew vehicle, the driver and passengers are in a car in direct interaction with the car seat while driving, which affects a sitting person in many areas such as safety, comfort, a feeling of comfort and customization to individual requirements, ergonomics and variability. All these effects are caused by one or a group of elements used in the construction of the seat. Objective assessment of the requirements for the construction of car seats, regardless of the characteristics of the occupant is not possible to provide a subjective feeling of comfort for any seated person. Therefore, we include in the design of automotive seat occupant's subjective feelings. It is clear that car seats must "adapt" individual characteristics of a seated man (weight, corpulence, age, gender,…). One of the subjective feelings of a man sitting in the seat is comfortable for any seated person defined differently. Correlation was found between comfort seats and contact pressure distribution depending on the weight of a seated man. It is understandable that every sitting person has a different distribution of contact pressure. This has resulted in the same seat each person differently seems comfortable-hard. The research objective is always to ensure maximum contact area for any seated person. Parameter that must be optimized is the hardness of butt pads sitting person (usually polyurethane pad coated fabric cover).In the conventional design seat cushion hardness is fixed, without the possibility of adaptability by the individuality sitting man. This article deals with the assessment, definition and optimization of hardness of pad in the automobile seat, the contact pressure distribution and determining the regulatory range of hardness depending on the weight of a seated man.

    Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

    Passenger car side impact crash tests and sled tests were conducted to investigate the influence of booster seats, near-side occupant characteristics and vehicle interiors on the responses of the Q6/Q6s child ATD positioned in the rear, far-side seating location. Data from nine side impact sled tests simulating a EuroNCAP AEMD barrier test were analyzed with data obtained from 44 side impact crash tests. The crash tests included: FMVSS 214 and IIHS MDB, moving car-to-stationary car and moving car-to-moving car. A Q6 or prototype Q6s ATD was seated on the far-side, using a variety of low and high back booster seats. Head and chest responses were recorded and ATD motions were tracked with high-speed videos. The vehicle lateral accelerations resulting from MDB tests were characterized by a much earlier and more rapid rise to peak than in tests where the bullet was another car. The near-side seating position was occupied by a Hybrid III 10-year-old ATD in the sled tests, and a rear or front facing child restraint or a 5th percentile side impact ATD in the crash tests. Head impacts occurred more frequently in vehicles where a forward facing child restraint was present behind the driver seat for both the low and high back booster seats. Pretensioners were found to reduce lateral head displacements in all sled test configurations but the greatest reduction in lateral excursion was obtained with a high back booster seat secured with LATCH and tested in combination with pretensioners.

    Full Text Available Literature shows that some health outcomes (e.g., eating, breathing, and speaking are directly related to posture. Evidence of outcomes mediated by wheelchair seated posture is limited to interface pressure, physical function, and wheelchair skills and safety. This study’s purpose was to develop and validate a rapid, low-burden, paper-pencil assessment of wheelchair seated posture for research use and to test feasibility of its use with a sample of older adults. We used a prospective design and a convenience sample of older adults who were receiving rehabilitation services in a community living center. Forty-nine older wheelchair users participated. Main measures were the Seated Posture Scale (SPS, Modified Ashworth Scale, Barthel Index, Visual Descriptor Scale, scale-content validity index (S-CVI, Cronbach alpha, and test-retest reliability. Rating by six experts yielded the overall content validity score (S-CVI of 0.744. Total SPS score correlated positively with physical function (Barthel Index, r = 0.46, p < 0.001 and negatively with muscle tone (Modified Ashworth Scale, r = –0.44, p = 0.001, supporting SPS construct validity. Internal consistency was 0.66 (Cronbach alpha. Test-retest reliability yielded Pearson product-moment correlations of 0.89 to 0.99. We conclude that the SPS has sufficient preliminary validity and reliability to support its use as an evaluation of wheelchair seated posture in outcomes research.

  19. Development of a Methodology to Gather Seated Anthropometry in a Microgravity Environment

    Science.gov (United States)

    Rajulu, Sudhakar; Young, Karen; Mesloh, Miranda

    2009-01-01

    The Constellation Program's Crew Exploration Vehicle (CEV) is required to accommodate the full population range of crewmembers according to the anthropometry requirements stated in the Human-Systems Integration Requirement (HSIR) document (CxP70024). Seated height is one of many critical dimensions of importance to the CEV designers in determining the optimum seat configuration in the vehicle. Changes in seated height may have a large impact to the design, accommodation, and safety of the crewmembers. Seated height can change due to elongation of the spine when crewmembers are exposed to microgravity. Spinal elongation is the straightening of the natural curvature of the spine and the expansion of inter-vertebral disks. This straightening occurs due to fluid shifts in the body and the lack of compressive forces on the spinal vertebrae. Previous studies have shown that as the natural curvature of the spine straightens, an increase in overall height of 3% of stature occurs which has been the basis of the current HSIR requirements. However due to variations in the torso/leg ratio and impact of soft tissue, data is nonexistent as to how spinal elongation specifically affects the measurement of seated height. In order to obtain this data, an experiment was designed to collect spinal elongation data while in a seated posture in microgravity. The purpose of this study was to provide quantitative data that represents the amount of change that occurs in seated height due to spinal elongation in microgravity environments. Given the schedule and budget constraints of ISS and Shuttle missions and the uniqueness of the problem, a methodology had to be developed to ensure that the seated height measurements were accurately collected. Therefore, simulated microgravity evaluations were conducted to test the methodology and procedures of the experiment. This evaluation obtained seat pan pressure and seated height data to a) ensure that the lap restraint provided sufficient

  1. Conical Seat Shut-Off Valve

    Science.gov (United States)

    Farner, Bruce

    2013-01-01

    A moveable valve for controlling flow of a pressurized working fluid was designed. This valve consists of a hollow, moveable floating piston pressed against a stationary solid seat, and can use the working fluid to seal the valve. This open/closed, novel valve is able to use metal-to-metal seats, without requiring seat sliding action; therefore there are no associated damaging effects. During use, existing standard high-pressure ball valve seats tend to become damaged during rotation of the ball. Additionally, forces acting on the ball and stem create large amounts of friction. The combination of these effects can lead to system failure. In an attempt to reduce damaging effects and seat failures, soft seats in the ball valve have been eliminated; however, the sliding action of the ball across the highly loaded seat still tends to scratch the seat, causing failure. Also, in order to operate, ball valves require the use of large actuators. Positioning the metal-to-metal seats requires more loading, which tends to increase the size of the required actuator, and can also lead to other failures in other areas such as the stem and bearing mechanisms, thus increasing cost and maintenance. This novel non-sliding seat surface valve allows metal-to-metal seats without the damaging effects that can lead to failure, and enables large seating forces without damaging the valve. Additionally, this valve design, even when used with large, high-pressure applications, does not require large conventional valve actuators and the valve stem itself is eliminated. Actuation is achieved with the use of a small, simple solenoid valve. This design also eliminates the need for many seals used with existing ball valve and globe valve designs, which commonly cause failure, too. This, coupled with the elimination of the valve stem and conventional valve actuator, improves valve reliability and seat life. Other mechanical liftoff seats have been designed; however, they have only resulted in

    The objective of this research is the exploration of seat belt use in Greece and particularly the identification of the parameters affecting seat belt use in Greece. A national field survey was conducted for the analytical recording of seat belt use. A binary logistic regression model was developed, and the impact of each parameter on seat belt use in Greece was quantified. Parameters included in the model concern characteristics of car occupants (gender, age and position in the car), the type of the car and the type of the road network. The data collection revealed that in Greece, the non-use of seat belt on the urban road network was higher than on the national and rural road network and young and older men use seat belts the least. The developed model showed that travelling on a national road is negative for not wearing the seat belt. Finally, the variable with the highest impact on not wearing a seat belt is being a passenger on the back seats. PMID:21452095

    In 2012 some children developed sepsis after playing together with a soap bubble toy. Microbiological testing revealed heavy contamination of the soap solution, which reasonably represented the vehicle of infection. We investigated the issue with a multidisciplinary approach: review of toy safety legislation; microbiological testing of additional samples; query of the RAPEX database for non-compliant soap bubbles; identification of major manufacturing districts. Microbiological contamination of industrial soap bubbles was widespread. Sixty-three notifications of batches contaminated by environmental microorganisms and opportunistic pathogens had been reported. The Chinese had a virtual monopoly of the soap bubble market. We identified two main manufacturing districts in Guangdong Province, both notable for degradation of their water resources. The use of untreated water for the industrial production of soap bubbles may explain the bacterial contamination. Existing legislation provides an unsatisfactory approach for managing microbiological hazards in sensitive toy categories and for identifying responsible parties in import and export of the products.

    Experimental results are presented of the vibrational characteristics of the automotive subsystem comprising the human body, seat, steering wheel and pedals. The magnitude of the vibrations transferred to a driver from the seat, steering wheel and pedals have been measured with both sinusoidal and random excitations in the vertical direction at frequencies up to 20 Hz. Measurement points were located on the surface of the head, chest, hip, thigh, shin, upper arm and lower arm. Eleven subjects were used to investigate the effect of some variable factors, such as arm angle, that may affect human dynamic behavior. It was found that arm angle in driving posture has a substantial influence on the dynamic behavior of the human body while driving. Some results are presented in the form of parametric graphs and tables. The results are useful for improving ride comfort, maneuverability and safety.

  9. Electrical Connector Mechanical Seating Sensor

    Arens, Ellen; Captain, Janine; Youngquist, Robert

    2011-01-01

    A sensor provides a measurement of the degree of seating of an electrical connector. This sensor provides a number of discrete distances that a plug is inserted into a socket or receptacle. The number of measurements is equal to the number of pins available in the connector for sensing. On at least two occasions, the Shuttle Program has suffered serious time delays and incurred excessive costs simply because a plug was not seated well within a receptacle. Two methods were designed to address this problem: (1) the resistive pin technique and (2) the discrete length pins technique. In the resistive pin approach, a standard pin in a male connector is replaced with a pin that has a uniform resistivity along its length. This provides a variable resistance on that pin that is dependent on how far the pin is inserted into a socket. This is essentially a linear potentiometer. The discrete approach uses a pin (or a few pins) in the connector as a displacement indicator by truncating the pin length so it sits shorter in the connector than the other pins. A loss of signal on this pin would indicate a discrete amount of displacement of the connector. This approach would only give discrete values of connector displacement, and at least one pin would be needed for each displacement value that would be of interest.

  14. Lumbar load attenuation for rotorcraft occupants using a design methodology for the seat impact energy-absorbing system

    Science.gov (United States)

    Moradi, Rasoul; Beheshti, Hamid; Lankarani, Hamid

    2012-12-01

    Aircraft occupant crash-safety considerations require a minimum cushion thickness to limit the relative vertical motion of the seat-pelvis during high vertical impact loadings in crash landings or accidents. In military aircraft and helicopter seat design, due to the potential for high vertical accelerations in crash scenarios, the seat system must be provided with an energy absorber to attenuate the acceleration level sustained by the occupants. Because of the limited stroke available for the seat structure, the design of the energy absorber becomes a trade-off problem between minimizing the stroke and maximizing the energy absorption. The available stroke must be used to prevent bottoming out of the seat as well as to absorb maximum impact energy to protect the occupant. In this study, the energy-absorbing system in a rotorcraft seat design is investigated using a mathematical model of the occupant/seat system. Impact theories between interconnected bodies in multibody mechanical systems are utilized to study the impact between the seat pan and the occupant. Experimental responses of the seat system and the occupant are utilized to validate the results from this study for civil and military helicopters according to FAR 23 and 25 and MIL-S-58095 requirements. A model for the load limiter is proposed to minimize the lumbar load for the occupant by minimizing the relative velocity between the seat pan and the occupant's pelvis. The modified energy absorber/load limiter is then implemented for the seat structure so that it absorbs the energy of impact in an effective manner and below the tolerable limit for the occupant in a minimum stroke. Results show that for a designed stroke, the level of occupant lumbar spine injury would be significantly attenuated using this modified energy-absorber system.

    Full Text Available Recently, sustainability has been a growing concern for many industries and especially for the transportation sector due to it being the second largest energy consumer and largest contributor of anthropogenic greenhouse gas emissions within the European Union. New legal restrictions on the emission rates have forced the automotive sector to examine different fuel-efficient technologies. Vehicle weight reduction is one of the most important methods of improving fuel efficiency and reducing CO2 emissions. Accordingly, lighter, safer, more fuel efficient, and environmentally sustainable vehicles are a priority for European authorities. In the present work, the passenger seat structure was considered as the area for lightweighting due to its important role in the mass of commercial vehicles in terms of numbers per vehicle. In addition, seat structures presented the best opportunity for weight reduction using new materials and design techniques. Detailed (3D finite element models of passenger seats were developed for finite element analyses (FEA. To obtain a lightweight and safe seat structure, different materials and thicknesses of profiles were analyzed. Lightweight passenger seat prototypes were developed and an overall 20% weight reduction was achieved including the structural frame, chassis and pillar. In addition, the new passenger seat meets ECE R14 safety norms.

    For car manufacturers, seat comfort is becoming more important in distinguishing themselves from their competitors. Therefore, many studies on participative seat comfort are carried out. In this paper, an objective assessment approach is reported which evaluates the concept of "optimal load distribution", based on the identification of a close relationship between the pressure on the seat and the discomfort felt by the person sitting. An in vivo measurement of the pressure in the spinal disc, which is an indicator of the load in the spine, was performed. For this research, a pressure sensor was implanted with a canula in the middle of the disc intervertebralis of a participant. The local pressure on the disc was established for the participant in an automobile seat set in various seat positions. The results indicate that in the seat position with the pressure distribution corresponding to the most comfortable posture the pressure in the intervertebral disc is lowest. The pressure in this position is 0.5 bar, while in the upright seated position the pressure is 1.6 bar.

  5. Evaluation of Seat Comfort of Office Armchairs: an Impact of Articulated Seat Support and Gas Spring

    Directory of Open Access Journals (Sweden)

    Jerzy Smardzewski

    2014-09-01

    Full Text Available This paper describes the application of an alternative seating system. The aim of this alternative approach was to determine the comfort of offi ce armchairs equipped with new construction solutions ensuring articulated support of the seat as well as articulated mounting of the gas spring. An offi ce armchair with a different seat support and gas spring was selected. Operational loads were applied to the seat surface. The following parameters were measured and calculated in the course of the performed experiments: contact area, average contact pressure and coeffi cient of seat pressure distribution (SPD. A new discomfort coeffi cient D expressing seat quality was elaborated. Preliminary data suggests that the prototypes provided greater sitting comfort than did the conventional chair. It was demonstrated that the new construction solution of the gas spring support guaranteed the highest comfort of the use of the examined armchairs.

    Directory of Open Access Journals (Sweden)

    Huiqian Lei

    2016-09-01

    Full Text Available Objective: to examine parents’ use of child restraint systems (CRS, and determine if parents’ knowledge of, attitude toward, and use behavior of child restraint systems have improved following enactment of child restraint use laws in other cities. Design: Observations and a cross-sectional survey of drivers transporting children 17 years and under were conducted at the gate of the schools and parking lots of hospitals in Shantou. Observers recorded the seating location of child passengers, the type of restraint, and appropriate use of CRS and safety belts based on the observation. Knowledge of and attitudes towards use of CRS were reported by the driver following observation. Results: Approximately 6.6% of passengers aged 0–12 were in CRS; rate of forward-facing CRS in children aged 3–5 (9.9% was higher than rear-facing CRS for children aged 0–2 (1.1% and booster seat use among children aged 6–12 (0.1%. Children younger than four years old (OR = 3.395, 95% CI = 2.125–5.424, drivers having a college or higher lever education (OR = 2.908, 95% CI = 1.878–4.500 and drivers wearing seatbelt (OR = 3.194, 95% CI = 1.605–6.356 had greater odds of CRS use. Over half (56.6% of parents might or would use CRS if they could rent CRSs with fees. Conclusions: The rate of CRS is still low in Shantou. Comprehensive public education programs supported by legislation might be an effective way to improve child passenger safety. Renting CRSs to parents could be a new approach to encourage use.

    Jiaxing, Zhan; Fard, Mohammad; Jazar, Reza

    2014-01-01

    A large number of independent and interacting factors affect seating comfort such as seat shape, stability, lumbar support and seat height. Although many subjective comfort studies have been conducted, few of them considered seating comfort from its subassembly level. This paper analyzed the automotive seat cushion designed with geared four-bar linkage for the seat height adjustment. The operation torque and lift distance of this mechanism was investigated as 2 major comfort factors. Ten cushions with this kind of design in the market were compared and assessed.

    2013-01-01

      “Safety is the highest priority”: this statement from CERN is endorsed by the CMS management. An interpretation of this statement may bring you to the conclusion that you should stop working in order to avoid risks. If the safety is the priority, work is not! This would be a misunderstanding and misinterpretation. One should understand that “working safely” or “operating safely” is the priority at CERN. CERN personnel are exposed to different hazards on many levels on a daily basis. However, risk analyses and assessments are done in order to limit the number and the gravity of accidents. For example, this process takes place each time you cross the road. The hazard is the moving vehicle, the stake is you and the risk might be the risk of collision between both. The same principle has to be applied during our daily work. In particular, keeping in mind the general principles of prevention defined in the late 1980s. These principles wer...

  14. SAFETY

    CERN Multimedia

    M. Plagge, C. Schaefer and N. Dupont

    2013-01-01

    Fire Safety – Essential for a particle detector The CMS detector is a marvel of high technology, one of the most precise particle measurement devices we have built until now. Of course it has to be protected from external and internal incidents like the ones that can occur from fires. Due to the fire load, the permanent availability of oxygen and the presence of various ignition sources mostly based on electricity this has to be addressed. Starting from the beam pipe towards the magnet coil, the detector is protected by flooding it with pure gaseous nitrogen during operation. The outer shell of CMS, namely the yoke and the muon chambers are then covered by an emergency inertion system also based on nitrogen. To ensure maximum fire safety, all materials used comply with the CERN regulations IS 23 and IS 41 with only a few exceptions. Every piece of the 30-tonne polyethylene shielding is high-density material, borated, boxed within steel and coated with intumescent (a paint that creates a thick co...

  15. Infant and Young Child Feces Management and Enabling Products for Their Hygienic Collection, Transport, and Disposal in Cambodia.

    Science.gov (United States)

    Miller-Petrie, Molly K; Voigt, Lindsay; McLennan, Lyn; Cairncross, Sandy; Jenkins, Marion W

    2016-02-01

    In Cambodia, children's feces are rarely disposed of in an improved sanitation facility. This study examines current practices and the role that enabling products may play in increasing hygienic management of infant and young child (IYC) feces in households with access to improved sanitation. A survey was conducted with the primary caregiver of a child under 5 years of age in 130 homes with an improved latrine in 21 villages across two provinces in Cambodia. Two focus group discussions per province were conducted after the survey to obtain caregiver feedback on new enabling products for hygienic management. Among caregivers, 63% reported child feces disposal in an improved latrine but only 36% reported doing so consistently. Besides child age, years of latrine ownership, caregiver age, consistency of adult latrine use, and presence of child feces management tools in the latrine were associated with hygienic disposal. The youngest caretakers with the newest latrines and youngest children were least likely to dispose of IYC feces hygienically, representing a key target group for interventions to improve hygienic disposal in Cambodia. Reusable diapers, child-friendly potties, and possibly latrine seats, that offer child safety, time and cost savings, and easy disposal and cleaning could potentially facilitate hygienic disposal for these ages.

  17. The Safe Environment for Every Kid model: promotion of children's health, development, and safety, and prevention of child neglect.

    Science.gov (United States)

    Dubowitz, Howard

    2014-11-01

    Child neglect is by far the most prevalent form of child maltreatment. There is a need to try to prevent this problem, and pediatric primary care offers an excellent opportunity. This article describes one such approach, the Safe Environment for Every Kid (SEEK) model. SEEK enables practitioners to identify and help address psychosocial problems facing many families. These include parental depression, substance abuse, major stress, intimate partner violence, harsh punishment, and food insecurity--problems that have been associated with neglect. Two large randomized, controlled trials yielded promising findings. Materials are now available to help practitioners implement this evidence-based practical model, thereby enhancing the primary care provided to children and their families.

  18. Active seat isolation for hybrid electric vehicles

    Leo, Donald J.; Malowicki, Mark; Buckley, Stephen J.; Naganathan, Ganapathy

    1999-07-01

    A feasibility study in the use of induced strain actuators for active seal isolation is described. The focus of the work is the isolation of lightweight automotive seats for hybrid-electric vehicles. The feasibility study is based on a numerical analysis of a three-degree-of-freedom vibration model of the seat. Mass and inertia properties are based on measurements from a powered seat that is found in current model year automobiles. Tradeoffs between vertical acceleration of the seat, actuator stroke requirements, and isolation frequency are determined through numerical analysis of the vibration model. Root mean square accelerations and actuator strokes are computed using power spectral densities that model broadband excitation and road excitation that is filtered by the vehicle suspension. Numerical results using the road excitation indicate that factors of two to three reduction in vertical acceleration are achieved when the active isolation frequency is reduced to approximately 1 Hz with damping factors on the order of 10 to 30 percent critical. More significant reductions are achieved in the case of broadband floor excitation. Root mean square actuator strokes for both case are int he range of 0.4 to 50 mm. Root mean square accelerations in the vertical direction are consistent with the levels found in standard comfort curves.

    In 1985 Qantas Airways (Australia) requested an ergonomics assessment of three pilots' seats so that one could be selected for fitting in all new aircraft as well replacement in existing aircraft. The Ipeco seat was chosen. In 1991, after all aircraft were fitted with the Ipeco seats, the company then requested a further evaluation of the seat to see if it was acceptable to the pilots and if there were any outstanding problems. A seat feature checklist plus a body chart discomfort rating scale was given to the total crew of 1030 pilots. The results from the 202 respondents indicated that although the pilots found the Ipeco seat an improvement on the Weber seat there were some modifications required. The main problems included insufficient adjustment range of the lumbar support area and the thigh supports, and infrequent replacement of the seat cushion. The body charts supported the checklist results in that the main areas of discomfort indicated were the buttocks and low back. Recommendations for improvements in design of the Ipeco seat, training in use and maintenance are presented. The method used in this study has application for field assessment of seating in a wide range of occupations, particularly bus drivers, truck drivers and train drivers, who spend long hours seated without being able to take breaks.

    2012-01-01

    The stability of a gravity dam against sliding along deep-seated weak planes is a universal and important problem encountered in the construction of dams.There is no recommended method for stability analysis of the dam on deep-seated weak planes under earthquake condition in Chinese design codes.Taking Tingzikou dam as an example,the research in this paper is focused on searching a proper way to evaluate the seismic safety of the dam against sliding along deep-seated weak planes and the probable failure modes of dam on deep-seated weak planes during earthquake.It is concluded that there are two probable failure modes of the dam along the main weak geological planes in the foundation.In the first mode,the concrete tooth under the dam will be cut and then the dam together with part foundation will slide along the muddy layer;in the second mode,the dam together with part foundation will slide along the path consist of the weak rock layer under the tooth and the muddy layer downstream the tooth.While there is no geological structure planes to form the second slip surface,the intersection of the main and the second slip surface is 40 to 80 m downstream from dam toe,and the angle between the second slip surface and the horizontal plane probably be 25 to 45 degrees.

    Singh, Harinder J.; Wereley, Norman M.

    2013-04-01

    An adaptive magnetorheological seat suspension (AMSS) was analyzed for optimal protection of occupants from shock loads caused by the impact of a helicopter with the ground. The AMSS system consists of an adaptive linear stroke magnetorheological shock absorber (MRSA) integrated into the seat structure of a helicopter. The MRSA provides a large controllability yield force to accommodate a wide spectrum for shock mitigation. A multiple degrees-of-freedom nonlinear biodynamic model for a 50th percentile male occupant was integrated with the dynamics of MRSA and the governing equations of motion were investigated theoretically. The load-stroke profile of MRSA was optimized with the goal of minimizing the potential for injuries. The MRSA yield force and the shock absorber stroke limitations were the most crucial parameters for improved biodynamic response mitigation. An assessment of injuries based on established injury criteria for different body parts was carried out.

    Paul, Gunther; Daniell, Nathan; Fraysse, François

    2012-01-01

    Seat pressure is known as a major factor of seat comfort in vehicles. In passenger vehicles, there is lacking research into the seat comfort of rear seat occupants. As accurate seat pressure measurement requires significant effort, simulation of seat pressure is evolving as a preferred method. However, analytic methods are based on complex finite element modeling and therefore are time consuming and involve high investment. Based on accurate anthropometric measurements of 64 male subjects and outboard rear seat pressure measurements in three different passenger vehicles, this study investigates if a set of parameters derived from seat pressure mapping are sensitive enough to differentiate between different seats and whether they correlate with anthropometry in linear models. In addition to the pressure map analysis, H-Points were measured with a coordinate measurement system based on palpated body landmarks and the range of H-Point locations in the three seats is provided. It was found that for the cushion, cushion contact area and cushion front area/force could be modeled by subject anthropometry, while only seatback contact area could be modeled based on anthropometry for all three vehicles. Major differences were found between the vehicles for other parameters.

    Pedestrian and motor vehicle-related injuries are leading causes of morbidity and mortality in children. Trauma centers have specialized resources to conduct interventions that improve the safety of whole communities. In the present study, we evaluated the effectiveness of a school-hospital partnership in increasing knowledge of pedestrian and motor vehicle safety among students and parents in a large, urban community. Staff from a Level I pediatric trauma center conducted educational interventions in an urban public school district. Elementary school students participated in a pedestrian safety program, middle school students completed a community safety program, and high school students learned about the dangers of drunk and distracted driving. Students completed pre- and post-tests. Parents in the neighboring community received child passenger safety education at two child restraint (CR) inspection events. A total of 2203 students participated at a total of nine schools. Post-test scores were significantly higher than pre-test scores for students in all three age groups and within each grade level. At CR inspection events, 67 CRs were inspected, 49 (73 %) of which were replaced with new age- and weight- appropriate CRs. The most common instance of improper CR use was loose CR fit in vehicle seat (33 %). All 120 observed instances of misuse were corrected by a certified Child Passenger Safety Technician. Educational interventions effectively increased knowledge of pedestrian and motor vehicle safety among students and parents. We have demonstrated the utility of a school-hospital partnership for furthering knowledge of safety in an urban community. PMID:25925719

    Full Text Available Determining the combustion characteristics of combustibles in high-speed trains is the foundation of evaluating the fire hazard on high-speed trains scientifically, and establishing effective active and passive fire precautions. In this study, the double seats in the compartments of CRH1 high-speed trains were used as the main research object. Under different test conditions, including the power of ignition sources and ventilation rates, full-scale furniture calorimeter tests were conducted to study important fire combustion characteristics such as the ignition characteristics of seats, heat release rate, mass loss rate, total heat release, temperature variation, and smoke release rate. The relationships among these parameters were analyzed and summarized into combustion behavior and characteristics, thus providing fundamental data and reference for the development of fire precautions and safety design of high-speed trains. The results in this test are as follows: (i The double seats of high-speed trains are relatively easy to ignite and susceptible to the fire ground environment. (ii The combustion temperature in the test apparatus exceeded 600 °C in only 2 min for the larger ignition source. (iii The heat release rate exceeded 800 kW. (iv The total heat release resulted mainly from flame combustion. (v The final mass loss rate was ∼30%. (vi The lowest light transmittance was <25%. (vii The change process of temperature with time has the same trend as the change process of heat release rate. (viii Suppressing flame combustion and controlling the smoke generated from the seat materials themselves played key roles in retarding the combustion of high-speed train seats.

    Electric powered wheelchairs (EPWs) are essential devices for people with disabilities as aids for mobility and quality of life improvement. However, the design of currently available common EPWs is still limited and makes it challenging for the users to drive in both indoor and outdoor environments such as uneven surfaces, steep hills, or cross slopes, making EPWs susceptible to loss of stability and at risk for falls. An alternative wheel-legged robotic wheelchair, "MEBot", was designed to improve the safety and mobility of EPW users in both indoor and outdoor environments. MEBot is able to elevate its six wheels using pneumatic actuators, as well to detect changes in the seat angle using a gyroscope and accelerometer. This capability enables MEBot to provide sensing for a dynamic self-leveling seat application that can maintain the center of mass within the boundaries of the wheelchair, thereby, improving EPW safety. To verify the effectiveness of the application, MEBot was tested on a motion platform with six degrees of freedom to simulate different slopes that could be experienced by the EPW in outdoor environments. The results demonstrate the robustness of the application to maintain the wheelchair seat in a horizontal reference against changes in the ground angle. PMID:26774421

    Full Text Available OBJECTIVE: This study aimed to describe the trade and microbiological quality of boiled quail eggs on the waterfront of Salvador , Bahia, Brazil, from the child labor perspective. METHODS: This cross-sectional study administered semi-structured questionnaires to 40 underage vendors and performed the microbiological assessment of 40 quail egg samples as follows: mesophilic aerobic microorganism count, coagulase-positive staphylococcus count, estimation of the most probable number of total and thermotolerant coliforms/Escherichia coli, and testing for Salmonella spp.. The results were compared with the standards provided by the Resolution RDC nº 12/2001, National Sanitary Surveillance Agency. RESULTS: The vendors were mostly female (57.5% students (95.0% aged 8 to 17 years. The most common reason for working was supplementation of the family income (57.5%. The mean gross income was R$38.31/day. Most of them presented inadequate personal hygiene but they recognized that foods could cause diseases. Many (47.5% vendors reported washing their hands up to twice daily. Mean mesophilic aerobic microorganism and coagulase-positive staphylococcus counts were 2.43 and 2.01 log colony-forming unit/g, respectively, and the estimated thermotolerant coliform contamination was 0.98 log most probable number/g. Escherichia coli was found in 15.0% of the samples and none contained Salmonella spp. Most (55.0% samples were noncompliant with the legislation. CONCLUSION: The results evidenced the presence of minors selling quail eggs on beaches of Salvador and suggest risk to consumers' health because of the detected contamination and vendors' ignorance of principles of hygiene.

    Revenue Management Systems (RMS) traditionally solve the seat allocation problem separately from the overbooking problem. Overbooking is managed by inflating the authorization levels obtained from seat allocation by various heuristics. This approach although suboptimal, is necessitated because...... by means of two transformations: The marginal revenue transformation of Fiig et al.

    The Alabama State Department of Education and the Governor's Study Group on School Bus Seat Belts authorized and funded a research project to investigate the effects of lap-shoulder seat belts on Alabama school buses. This article performs an empirical analysis to address an important component of the study - factors that impact students' decisions about wearing seat belts or not on school buses. Discrete choice modeling framework is applied to quantify relative influences of various factors. To obtain the disaggregate level information on individual student's characteristics and trip properties, a new data collection protocol is developed. Eleven variables are investigated and eight of them are found to have significant impacts. They are age, gender, the home county of a student, a student's trip length, time of day, presence and active involvement of bus aide, and two levels of bus driver involvement. The resulting model fits the data well and reveals several trends that have been overlooked or underestimated in the literature. The model can also be used to predict the change of seat belt usage rate caused by the change of impact factors. This is helpful in identifying the most cost-effective ways to improve compliance rate, which is critical to bring the added safety benefit of seat belts into effect. This article is the first to quantify relative impacts of a range of variables using rigorous statistical modeling techniques. This study will contribute to the literature and provide valuable insights to the practice of school transportation management. PMID:21658490

    Due to the high energy-absorption potential of metal foams and their excellent weight-to-stiffness ratio, metal foams in car seats may contribute to both increasing passenger safety and also weight reduction. An overview and the first results of a research project to apply cellular metals as energy-absorbing components in car seats in case of a crash are discussed. The project aims are material optimization and the generation of standards and design criteria for a novel technical application of metal foams. The first results reveal the microstructure and mechanical behavior of different metal foams and metal-foam/metal-sheet sandwich structures. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

    Future space shuttle missions presented by NASA might require the shuttle to rendezvous with the Russian space station Mir for the purpose of transporting astronauts back to earth. Due to the atrophied state of these astronauts, a special seating system must be designed for their transportation. The main functions of this seating system are to support and restrain the astronauts during normal reentry flight and to dampen some of the loading that might occur in a crash situation. Through research, the design team developed many concept variants for these functional requirements. By evaluating each variant, the concepts were eliminated until the four most attractive designs remained. The team used a decision matrix to determine the best concept to carry through embodiment. This concept involved using struts for support during reentry flight and a spring damper/shock absorber system to dampen crash landing loads. The embodiment design process consisted of defining the layout of each of the main functional components, specifically, the seat structure and the strut structure. Through the use of MCS/pal two, the design was refined until it could handle all required loads and dampen to the forces specified. The auxiliary function carriers were then considered. Following the design of these components, the complete final layout could be determined. It is concluded that the final design meets all specifications outlined in the conceptual design. The main advantages of this design are its low weight, simplicity, and large amount of function sharing between different components. The disassembly of this design could potentially present a problem because of time and size constraints involved. Overall, this design meets or exceeds all functional requirements.

    2010-01-01

    Effectiveness of the rear seat in protecting occupants of different age groups in frontal crashes for 2000–2009 model years (MY) of vehicles was estimated and compared to 1990–1999 model years of vehicles. The objective was to determine the effectiveness of the rear seat compared to the front seat for various age groups in newer model year vehicles. The double paired comparison method was used to estimate relative effectiveness. For belted adults of the 25–49 age group, the fatality reduction effectiveness of the rear seat compared to the right front seat was 25 % (CI 11% to 36%), in the 1990–1999 model year vehicles. The relative effectiveness was −31% (CI −63% to −5%) for the same population, in the 2000–2009 model year vehicles. For restrained children 0–8 years old, the relative effectiveness was 55% (CI 48% to 61%) when the vehicles were of the 1990–1999 period. The level of effectiveness for this age group was reduced to 25% (CI −4% to 46%) in the 2000–2009 MYs of vehicles. Results for other age groups of belted occupants have followed a similar trend. All belted adult occupants of 25+ years old were significantly less protected in rear seats as compared to right front seats in the 2000–2009 model years of vehicles. For unbelted occupants however, rear seats were still a safer position than front seats, even in the 2000–2009 model years of vehicles. PMID:21050599

    1997-05-06

    A temperature climate control system comprises a variable temperature seat, at least one heat pump, at least one heat pump temperature sensor, and a controller. Each heat pump comprises a number of Peltier thermoelectric modules for temperature conditioning the air in a main heat exchanger and a main exchanger fan for passing the conditioned air from the main exchanger to the variable temperature seat. The Peltier modules and each main fan may be manually adjusted via a control switch or a control signal. Additionally, the temperature climate control system may comprise a number of additional temperature sensors to monitor the temperature of the ambient air surrounding the occupant as well as the temperature of the conditioned air directed to the occupant. The controller is configured to automatically regulate the operation of the Peltier modules and/or each main fan according to a temperature climate control logic designed both to maximize occupant comfort during normal operation, and minimize possible equipment damage, occupant discomfort, or occupant injury in the event of a heat pump malfunction.

    2014-01-01

    The objective of this study was to identify how physiological measures relate to self-reported vehicle seating discomfort. Twelve subjects of varied anthropometric characteristics were enrolled in the study. Subjects sat in two seats over a 2-h period and were evaluated via three physiological measures (near-infrared spectroscopy, electromyography and pressure mapping) yielding six testing sessions. Subjective discomfort surveys were recorded before and after each session for nine regions of the body. Conditional classification discomfort models were developed through dichotomised physiological responses and anthropometry to predict subjective discomfort in specific body locations. Models revealed that subjects taller than 171 cm with reduced blood oxygenation in the biceps femoris or constant, low-level muscle activity in the trapezius tended to report discomfort in the lower extremities or neck, respectively. Subjects weighing less than 58 kg with reduced blood oxygenation in the biceps femoris or unevenly distributed pressure patterns tended to report discomfort in the buttocks. The sensitivities and specificities of cross-validated models ranged between 0.69 and 1.00. PMID:24606493

    Wang, Chunlei; Zhang, Xinjie; Guo, Konghui; Lv, Jiming; Yang, Yi

    2016-11-01

    Scissor seat suspension has been applied widely to attenuate the cab vibrations of commercial vehicles, while its design generally needs a trade-off between the seat acceleration and suspension travel, which creates a typical optimisation issue. A complexity for this issue is that the optimal dynamics parameters are not easy to approach solutions fast and unequivocally. Hence, the hierarchical optimisation on scissor seat suspension characteristic and structure is proposed, providing a top-down methodology with the globally optimal and fast convergent solutions to compromise these design contradictions. In details, a characteristic-oriented non-parametric dynamics model of the scissor seat suspension is formulated firstly via databases, describing its vertical dynamics accurately. Then, the ideal vertical stiffness-damping characteristic is cascaded via the characteristic-oriented model, and the structure parameters are optimised in accordance with a structure-oriented multi-body dynamics model of the scissor seat suspension. Eventually, the seat effective amplitude transmissibility factor, suspension travel and the CPU time for solving are evaluated. The results show the seat suspension performance and convergent speed of the globally optimal solutions are improved well. Hence, the proposed hierarchical optimisation methodology regarding characteristic and structure of the scissor seat suspension is promising for its virtual development.

  1. Rethinking design parameters in the search for optimal dynamic seating.

    Science.gov (United States)

    Pynt, Jennifer

    2015-04-01

    Dynamic seating design purports to lessen damage incurred during sedentary occupations by increasing sitter movement while modifying muscle activity. Dynamic sitting is currently defined by O'Sullivan et al. ( 2013a) as relating to 'the increased motion in sitting which is facilitated by the use of specific chairs or equipment' (p. 628). Yet the evidence is conflicting that dynamic seating creates variation in the sitter's lumbar posture or muscle activity with the overall consensus being that current dynamic seating design fails to fulfill its goals. Research is needed to determine if a new generation of chairs requiring active sitter involvement fulfills the goals of dynamic seating and aids cardio/metabolic health. This paper summarises the pursuit of knowledge regarding optimal seated spinal posture and seating design. Four new forms of dynamic seating encouraging active sitting are discussed. These are 1) The Core-flex with a split seatpan to facilitate a walking action while seated 2) the Duo balans requiring body action to create rocking 3) the Back App and 4) Locus pedestal stools both using the sitter's legs to drive movement. Unsubstantiated claims made by the designers of these new forms of dynamic seating are outlined. Avenues of research are suggested to validate designer claims and investigate whether these designs fulfill the goals of dynamic seating and assist cardio/metabolic health. Should these claims be efficacious then a new definition of dynamic sitting is suggested; 'Sitting in which the action is provided by the sitter, while the dynamic mechanism of the chair accommodates that action'.

    2010-06-01

    Full Text Available Design optimization of seat cushions is associated with the need to investigate their softness using, for this purpose, various kinds of loading pads. The aim of the investigation was: to determine seat cushion stiffness of a chair selected from a set of dining-room furniture, to determine values and distributions of contact strains on the seat surface caused by loading pad of different hardness, numerical calculation of contact strains between the seat cushion and the loading pad and to verify the results of these calculations with the results of laboratory experiments. The performed tests showed that the assessment of the seat cushion stiffness and the evaluation of contact stresses on their surface should be carried out using an equally stiff loading pad. In numerical calculations, polyurethane foams should be modeled as hyperfoam bodies of σ=f(ε characteristics determined in an axial compression test. Contact stresses between the seat cushion and the user’s body should be reduced as a result of application of a frictionless connection of thin layers of polyurethane foams with foam forming the proper elastic layer of the seat.

    Deep-seated gas is defined in this paper as natural gas generated under the combined action of high temperature,high pressure, and environment media. As to organic matter vertical evolution, deep-seated gas is natural gas, which is generated and deposited under the position of an oil genera-tion window. Deep-seated gas exploration is an important potential field for oil-gas exploration. Also, it is an inexorable trend to the further development of oil and gas provinces.In this paper, the authors will examine and distinguish the concept of deep-seated gas, and discuss the distribution and gas source of deep-seated gas. It is pointed out that kerogen,assemble dissoluble organic matter and disperse dissoluble organic matter all have Contributed to deep-seated gas generation, especially disperse dissoluble organic matter in composite and superimposed sedimentary basin. In the end,according to the structural evolution and hydrocarbon source rock depositional distribution, the distribution of deep-seated gas in China is predicted.

    Motor vehicle crashes (MVC) are the leading cause of death from severe injuries on the Pine Ridge Indian Reservation (PRIR), averaging 16 MVC deaths per year from 2002 to 2011. The Sacred Cargo Coalition was established in PRIR in 2007 to implement intervention strategies to increase seat belt usage and reduce MVC fatalities, including seat belt law enforcement, creating a traffic court system, and educational campaigns on MVC prevention. The study described in this article examined the effectiveness of the interventions on increasing the seat belt usage rates and reducing MVC deaths. Secondary data were collected from the National Highway Traffic Safety Administration and other federal and local agencies. Seat belt usage rates increased an average of 6.8 percentage points from 2007 (10%) to 2012 (44%). MVC fatalities decreased by 46.7% from the preintervention to the intervention period. Maintenance and improvement of the intervention strategies may be achieved by seeking additional funding and including appropriate engineering activities in PRIR. PMID:26867291

    Full Text Available Unstable back support against gravity results in a forward head posture and contributes to buttocks pressure ulcers. However, the association between these health problems and a wheelchair backrest is unclear. Our newly developed wheelchair (N-WC supports the back of the pelvis and thorax from obliquely underneath. The purpose of this study was to investigate the effect of different backrest shapes on head–neck alignment and seated pressure. Data from 28 healthy subjects were analyzed. Outcome measures were head–neck alignment angles, support angles of the backrest, and pressure distributions on the supporting surfaces. Compared with a typical wheelchair that has a flat backrest, the seat pressure decreased and the center of pressure was located in the middle of both the seat and backrest in the N-WC. Moreover, the head–neck alignment when seated in the N-WC was upright. These results highlight the importance of the shape of the wheelchair backrest.

  18. Deprived children or deprived neighbourhoods? A public health approach to the investigation of links between deprivation and injury risk with specific reference to child road safety in Devon County, UK

    Directory of Open Access Journals (Sweden)

    Hewson Paul

    2004-05-01

    Full Text Available Abstract Background Worldwide, injuries from road traffic collisions are a rapidly growing problem in terms of morbidity and mortality. The UK has amongst the worst records in Europe with regard to child pedestrian safety. A traditional view holds that resources should be directed towards training child pedestrians. In order to reduce socio-economic differentials in child pedestrian casualty rates it is suggested that these should be directed at deprived children. This paper seeks to question whether analysis of extant routinely collected data supports this view. Methods Routine administrative data on road collisions has been used. A deprivation measure has been assigned to the location where a collision was reported, and the home postcode of the casualty. Aggregate data was analysed using a number of epidemiological models, concentrating on the Generalised Linear Mixed Model. Results This study confirms evidence suggesting a link between increasing deprivation and increasing casualty involvement of child pedestrians. However, suggestions are made that it may be necessary to control for the urban nature of an area where collisions occur. More importantly, the question is raised as to whether the casualty rate is more closely associated with deprivation measures of the ward in which the collision occurred than with the deprivation measures of the home address of the child. Conclusion Conclusions have to be drawn with great caution. Limitations in the utility of the officially collected data are apparent, but the implication is that the deprivation measures of the area around the collision is a more important determinant of socio-economic differentials in casualty rates than the deprivation measures of the casualties' home location. Whilst this result must be treated with caution, if confirmed by individual level case-controlled studies this would have a strong implication for the most appropriate interventions.

    Going on a car with autistic children needs a special handling. Autistic children that tend to be hyperactive in the car may disturb driving. A tool is needed to keep them in a calm state when they are in the car. Autist Mobile Seat is an aid for the autistic children when going on a car. The aid is an additional seat paired with the main seat of the car. This aid consists of three main things: Main frame, body skin, and pneumatic system. Frame as the main component supporting the Autist Mobile Seat functions as a holder as well as a body skin retainer in order to be able to retain the body of the autistic children. The strength of the frame from this Autist Mobile Seat should be counted as an anticipation from the failure of the frame function when receiving load when used by the autistic children in the car. Consequently, a test on the frame of the Autist Mobile Seat towards the load received should be conducted by using a method of FEM (Finite Element Method) with the help of commercial software. The simulation produces the maximum strength, the frame towards the load received as well as the critical point on the frame when loading occurs.

    For modelling purposes and for evaluation of driver's seat performance in the vertical direction various mechano-mathematical models of the seated human body have been developed and standardized by the ISO. No such models exist hitherto for human body sitting in an upright position in a cushioned seat upper part, used in industrial environment, where the fore-and-aft vibrations play an important role. The interaction with the steering wheel has to be taken into consideration, as well as, the position of the human body upper torso with respect to the cushioned seat back as observed in real driving conditions. This complex problem has to be simplified first to arrive at manageable simpler models, which still reflect the main problem features. In a laboratory study accelerations and forces in x-direction were measured at the seat base during whole-body vibration in the fore-and-aft direction (random signal in the frequency range between 0.3 and 30 Hz, vibration magnitudes 0.28, 0.96, and 2.03 ms(-2) unweighted rms). Thirteen male subjects with body masses between 62.2 and 103.6 kg were chosen for the tests. They sat on a cushioned driver seat with hands on a support and backrest contact in the lumbar region only. Based on these laboratory measurements a linear model of the system-seated human body and cushioned seat in the fore-and-aft direction has been developed. The model accounts for the reaction from the steering wheel. Model parameters have been identified for each subject-measured apparent mass values (modulus and phase). The developed model structure and the averaged parameters can be used for further bio-dynamical research in this field. PMID:16962599

    Techniques using intracavitary or interstitial applicators have been proposed because extracorporeal HIFU techniques are not always suitable for deep-seated tumors. Bones or gaseous pockets may indeed be located in the intervening tissue. The objective is to bring the ultrasound source as close as possible to the target through natural routes in order to minimize the effects of attenuation and phase aberration along the ultrasound pathway. Under these circumstances, it becomes possible to use higher frequency, thus increasing the ultrasonic absorption coefficient and resulting in more efficient heating of the treatment region. In contrast to extra-corporeal applicators, the design of interstitial probes imposes additional constraints relative to size and ergonomy. The goal of this paper is to present the range of miniature interstitial applicators we developed at INSERM for various applications. The sources are rotating plane water-cooled transducers that operate at a frequency between 3 and 10 MHz depending on the desired therapeutic depth. The choice of a plane transducer rather than divergent sources permits to extend the therapeutic depth and to enhance the angular selectivity of the treatment Rotating single element flat transducer can also be replaced by cylindrical arrays for rotating electronically a reconstructed plane wave. When extended zone of coagulation are required, original therapeutic modalities combining cavitation and thermal effects are used. These methods consist in favoring in depth heating by increasing the acoustic attenuation away from the transducer with the presence of bubbles. When associated to modern imaging modalities, these minimally invasive therapeutic devices offer very promising options for cancer treatment. For examples, two versions of an image-guided esophageal applicator are designed: one uses a retractable ultrasound mini probe for the positioning of the applicator, while the other is MRI compatible and offers on line

    Seating comfort is becoming increasingly important for the automotive industry. Car manufacturers use seating comfort to distinguish their products from those of competitors. However, the development and design of a new, more comfortable seat is time consuming and costly. The introduction of computer models of human and seat will accelerate this process. The contact interaction between human and seat is an important factor in the comfort sensation of subjects. This paper presents a finite element (FE) model of the human buttocks, able to predict the pressure distribution between human and seating surface by its detailed and realistic geometric description. A validation study based on volunteer experiments shows reasonable correlation in pressure distributions between the buttocks model and the volunteers. Both for simulations on a rigid and a soft cushion, the model predicts realistic seat pressure distributions. A parameter study shows that a pressure distribution at the interface between human and seat strongly depends on variations in human flesh and seat cushion properties.

    Railway seat inventory control strategies play a crucial role in the growth of profit and train load factor. The railway passenger seat inventory control problem in China was addressed. Chinese passenger railway operation features and seat inventory control practice were analyzed firstly. A dynamic demand forecasting method was introduced to forecast the coming demand in a ticket booking period. By clustering, passengers’ historical ticket bookings were used to forecast the demand to come in a ticket booking period with least squares support vector machine. Three seat inventory control methods:non-nested booking limits, nested booking limits and bid-price control, were modeled under a single-fare class. Different seat inventory control methods were compared with the same demand based on ticket booking data of Train T15 from Beijing West to Guangzhou. The result shows that the dynamic non-nested booking limits control method performs the best, which gives railway operators evidence to adjust the remaining capacity in a ticket booking period.

    The current status of hyperthermia for deep-seated tumor is reviewed. Heating methods include external heating, intraluminal heating and interstitial heating, all of which have inherent advantages and disadvantages. Hyperthermia alone has significant effects on deep-seated tumors. The combination of hyperthermia and radiotherapy has been widely applied, resulting in 10-15% complete regression and 10-40% partial regression in the treatment of locally advanced tumors. The response rate of thermoradiotherapy was higher than that of radiotherapy for tumors in the brain, rectum and esophagus in the non-randomized study. The clinical application of thermochemotherapy is increasing and its effect is demonstrated in the prevention and treatment of peritoneal dissemination of gastric cancers. Reports of serious complications are rare. The technology for deep-heating and thermometry, and the new criteria for the assessment of thermotherapy for deep-seated tumors seems a promising new treatment modality.

    As of 1986, all 50 states had implemented mandatory child restraint laws. When used correctly, restraint systems have been proven to reduce the number of fatalities, hospitalizations, and injuries. To date, there is little information regarding compliance with restraint systems for disabled children. There are no data available on fatalities of or injuries to disabled children. This study assessed the restraint system (if any) used in the transportation of disabled children with special restraint needs. We conducted a survey to determine the restraint practices used in transporting these children to school, to our outpatient clinic, and around home. Our survey found that two thirds of the handicapped children reviewed were transported unsafely in at least one mode of transportation. We recommend that health care providers review the transportation needs of their handicapped patients in order to ensure safe transportation.

    Multilayered samples of contemporary and improved fire-resistant aircraft seat materials were evaluated for their rates of heat release and smoke generation. Top layers with glass-fiber block cushion were evaluated to determine which materials, based on their minimum contributions to the total heat release of the multilayered assembly, may be added or deleted. The smoke and heat release rates of multilayered seat materials were then measured at heat fluxes of 1.5 and 3.5 W/cm2. Abrasion tests were conducted on the decorative fabric covering and slip sheet to ascertain service life and compatibility of layers

    Full Text Available Sikorsky S-61 or better known as “Nuri” had served the Malaysian aviation sector for the past four decades. It is mainly used for transportation, combat search and rescue purposes. However, there were Nuri helicopter crashes or accident cases reported during its operation period which involved loss of its occupants. The pilot survivability rate can be improved provided that the vertical impact loading on the helicopter is reduced during the crash accident. Utilization of an energy absorbing pilot seat or cockpit structure maybe one of the approaches to minimize the impact shock exerted to the occupants. However, the shock or maximum acceleration of the cockpit/pilot seat has to be first determined before a thorough design scheme can be undertaken. In this study, a vertical crash event of the Nuri pilot seat from 500 feet altitude was simulated and the maximum acceleration rate was determined using MSC PATRAN/LSDYNA. The pilot survivability was determined by comparing the result with human tolerance criteria data available in other published works. From the result, it was found that the maximum acceleration of the Nuri pilot seat was 584.4g at 19. 63 milliseconds, thus it can be concluded that the survivability aspect of the pilot is fatal when compared to other published works.

    The demands on higher performance and the increasing use of alternative fuels chal-lenge engine valves now with greater wear problems than before. A seat wear simulator was builtto evaluate the compatibility and wear of valve and seat insert. The rig test results have been suc-cessfully correlated with engine test results. In this study, intake valves made from Sil 1 materialwere treated with salt bath nitride processes and tested against six different insert materials. Wearresistance of these combinations was ranked and compared to the Sil 1 valve without nitriding.The test results demonstrate that nitriding improved valve seat wear resistance. In the total valveseat recession ranking, the combination of nitrided Sil 1 valve against T 400 insert exhibited theleast total recession among the nineteen combinations of valve and insert tested. The results indi-cate that the valve seat wear mechanisms are a complex combination of adhesion and shearstrain. The nitrides in the compound layer of nitrided valves gave strong atomic bonding, higherhardness, compressive residual stresses, and possible low friction, thus resulted in the superiorwear performance.

    A study was undertaken recently for the Federal Office of Road Safety in Australia of 150 modern vehicle crashes where at least one of the vehicle occupants was admitted to hospital. The types of injuries sustained by occupants of modern Australian passenger cars involved in road crashes (including points of contact within the vehicle) were assessed to provide direction for future improvements in occupant protection. Seat belt performance in all seating positions was of particular interest. While the limited number of cases did not permit a full and detailed statistical analysis of these data, the findings nevertheless show there is scope for improving occupant protection for drivers and passengers of modern passenger cars.

    2014-05-01

    We use the model r.slope.stability to explore the chances and challenges of physically-based modelling of deep-seated slope stability in complex geology over broad areas and not on individual slopes. The model is developed as a C and python-based raster module within the GRASS GIS software. It makes use of a modification of the three-dimensional sliding surface model proposed by Hovland (1977) and revised and extended by Xie and co-workers (2006). Given a digital elevation model and a set of thematic layers (lithological classes and related geotechnical parameters), the model evaluates the slope stability for a large number of randomly selected potential slip surfaces, ellipsoidal in shape. The bottoms of soil or bedrock layers can also be considered as potential slip surfaces by truncating the ellipsoids. Any single raster cell may be intersected by multiple sliding surfaces, each associated with a computed safety factor. For each pixel, the lowest value of the safety factor and the depth of the associated slip surface are stored. This information can be used to obtain a spatial overview of the potentially unstable regions in the study area. The r.slope.stability model can be executed both in a soil class-based mode, where the input data are mainly structured according to horizontally defined soil classes, and in a layer-based mode, where the data are structured according to a potentially large number of layers. Here, we test the model for the layer-based mode, allowing for the analysis of relatively complex geologic structures. We test the model in the Collazzone area, Umbria, central Italy, which is susceptible to landslides of different types. According to field observations in this area, morpho-structural settings (i.e., the orientation and dip of the geological layers) play a crucial role for the distribution of the deep-seated landslides. We have prepared a lithological model based on aerial photointerpretation, field survey and surface information on the

    1996-03-01

    An observational cross-sectional survey showed that 21.1% of private motor vehicle drivers and 13.5% of front seat passengers voluntarily wore seat belts in Kingston, Jamaica, where there is no law requiring this. Rear passenger utilisation was not examined. Compared to males, females were significantly more likely to wear seat belts when driving but not as front seat passengers. Of all motor vehicles examined, 10.1% were not equipped with seat belts. The oldest group of vehicles were mostly not fitted with seat belts. Drivers of older vehicles were significantly less likely to use seat belts even when the vehicles were equipped with belts. Implementation of legislation can reduce mortality, morbidity and costs from road traffic accidents which are relatively frequent in Jamaica. Male drivers, drivers of older vehicles and all passengers may require specific targeting in an educational and enforcement campaign should legislation, which is highly desirable, be implemented.

  1. The transmission of vertical vibration through seats: Influence of the characteristics of the human body

    Science.gov (United States)

    Toward, Martin G. R.; Griffin, Michael J.

    2011-12-01

    The transmission of vibration through a seat depends on the impedance of the seat and the apparent mass of the seat occupant. This study was designed to determine how factors affecting the apparent mass of the body (age, gender, physical characteristics, backrest contact, and magnitude of vibration) affect seat transmissibility. The transmission of vertical vibration through a car seat was measured with 80 adults (41 males and 39 females aged 18-65) at frequencies between 0.6 and 20 Hz with two backrest conditions (no backrest and backrest), and with three magnitudes of random vibration (0.5, 1.0, and 1.5 m s -2 rms). Linear regression models were used to study the effects of subject physical characteristics (age, gender, and anthropometry) and features of their apparent mass (resonance frequency, apparent mass at resonance and at 12 Hz) on the measured seat transmissibility. The strongest predictor of both the frequency of the principal resonance in seat transmissibility and the seat transmissibility at resonance was subject age, with other factors having only marginal effects. The transmissibility of the seat at 12 Hz depended on subject age, body mass index, and gender. Although subject weight was strongly associated with apparent mass, weight was not strongly associated with seat transmissibility. The resonance frequency of the seat decreased with increases in the magnitude of the vibration excitation and increased when subjects made contact with the backrest. Inter-subject variability in the resonance frequency and transmissibility at resonance was less with greater vibration excitation, but was largely unaffected by backrest contact. A lumped parameter seat-person model showed that changes in seat transmissibility with age can be predicted from changes in apparent mass with age, and that the dynamic stiffness of the seat appeared to increase with increased loading so as to compensate for increases in subject apparent mass associated with increased sitting

    Hillman, Susan J; Hollington, James

    2016-05-01

    This technical note proposes a method to measure and compare seated postures. The three-dimensional locations of palpable anatomical landmarks corresponding to the anterior superior iliac spines, clavicular notch, head, shoulders and knees are measured in terms of x, y and z co-ordinates in the reference system of the measuring apparatus. These co-ordinates are then transformed onto a body-based axis system which allows comparison within-subject. The method was tested on eleven unimpaired adult participants and the resulting data used to calculate a Least Significant Difference (LSD) for the measure, which is used to determine whether two postures are significantly different from one another. The method was found to be sensitive to the four following standardised static postural perturbations: posterior pelvic tilt, pelvic obliquity, pelvic rotation, and abduction of the thighs. The resulting data could be used as an outcome measure for the postural alignment aspect of seating interventions in wheelchairs. PMID:26920073

Extending standing, while unpleasant for most, is often not recommended for certain groups, such as the elderly or those with chronic conditions. This paper relates to a foldable, a portable stool, and more particularly, to a portable stool that can be carried in a compact manner and utilized in situations of inadequate seating. Study Objective of this paper is that we can provide some means to the elderly people or those with chronic conditions. Who do not get seat in the train/buses/public places should be beneficial. Also one can use it anywhere at their own will. This paper relates to foldable/ portable stools and has its general objective to produce a device of such a kind which is of compact nature when folded or in inoperative position and is of strong and sturdy character when open or operative.

    Although children are frequently required to sit upright, it is often difficult to maintain this posture when performing cognitive tasks. Information about the relationship between a cognitive tasks and postural seating control is important for children to complete tasks more effectively. To determine the muscle activity and body sway of children in a seated posture while performing a cognitive task, changes in muscle activity and center of pressure (COP) were recorded while 4(th) grade children performed arithmetic tasks. Electromyography was recorded from the internal oblique and lumbar multifidus muscles, and the COP was recorded using a baropodometer placed on the stool. These variables were measured during easy (EA) and difficult (DA) arithmetic tasks. EMG activity decreased during the EA and DA tasks, while the COP was displaced in the DA task. The results of the arithmetic tasks were not related to the EMG or COP changes. Attention to maintain a seated posture may be reduced when children perform cognitive tasks. Therefore, it may be better to allow children to alter their posture especially when they are performing difficult tasks. In this research, we only used arithmetic tasks as the cognitive exercise, and therefore, other types of tasks should be examined. PMID:26317316

  17. Multi-leg Seat Inventory Control Based on EMSU and Virtual Bucket

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Expected marginal seat revenue (EMSR is a well-known method for airline seat inventory control airlines. However, this method employs a static model to study the dynamic reservation process, and does not take into account the risk tolerance of policy makers. Expected marginal seat utility (EMSU replaces revenue by utility, which addresses the real situation of seat inventory control. However, there is still a lack of multi-leg seat control algorithms based on EMSU. Therefore, using EMSU and bucket algorithms, this paper applies the Markov decision-making process to simulate the flight reservation process and builds a dynamic multi-leg seat inventory control model. Experimental results validate the effectiveness of the proposed method.

  18. Training toddlers seated on mobile robots to drive indoors amidst obstacles.

    2011-06-01

    Mobility is a causal factor in development. Children with mobility impairments may rely upon power mobility for independence and thus require advanced driving skills to function independently. Our previous studies show that while infants can learn to drive directly to a goal using conventional joysticks in several months of training, they are unable in this timeframe to acquire the advanced skill to avoid obstacles while driving. Without adequate driving training, children are unable to explore the environment safely, the consequences of which may in turn increase their risk for developmental delay. The goal of this research therefore is to train children seated on mobile robots to purposefully and safely drive indoors. In this paper, we present results where ten typically-developing toddlers are trained to drive a robot within an obstacle course. We also report a case study with a toddler with spina-bifida who cannot independently walk. Using algorithms based on artificial potential fields to avoid obstacles, we create force field on the joystick that trains the children to navigate while avoiding obstacles. In this "assist-as-needed" approach, if the child steers the joystick outside a force tunnel centered on the desired direction, the driver experiences a bias force on the hand. Our results suggest that the use of a force-feedback joystick may yield faster learning than the use of a conventional joystick.

    Full Text Available Inadvertent access to website addresses and spam e-mails continue to make pornography rampant on the Internet in schools, homes, and libraries. Collectively, parents, teachers, and members of the community must become more aware of the risks and consequences of open access to the Internet, and the distinction between censorship and Internet access filtering. Parental involvement is crucial for raising children with healthy Internet habits to access social and educational materials. Although generations have coped with different times and trials, technology is ushering in new trials. Parents and communities cannot ignore the present and future technology ingrained into the lives of children. This paper contends that parents armed with legislation and technological security devices for access to the Internet ought to strengthen the character of online Internet safety. The discussion is focused on the roles that parents, communities, technology, and laws should play in order to protect children from obscene and pornographic threats from cyberspace. It is argued that the roles of education and technology should outweigh the legislative interventions of governments. A critique of significant litigations and laws on obscenity and pornography is presented. The paper offers a variety of security tools and techniques for protecting children from Internet access to obscene and pornographic materials. The impacts of pornographic materials on the welfare of children, adolescents, women, and families are discussed.

  3. Development of Methodology to Gather Seated Anthropometry Data in a Microgravity Environment

    Rajulu, Sudhakar; Young, Karen; Mesloh, Miranda

    2010-01-01

    The Constellation Program is designing a new vehicle based off of new anthropometric requirements. These requirements specify the need to account for a spinal elongation factor for anthropometric measurements involving the spine, such as eye height and seated height. However, to date there is no data relating spinal elongation to a seated posture. Only data relating spinal elongation to stature has been collected in microgravity. Therefore, it was proposed to collect seated height in microgravity to provide the Constellation designers appropriate data for their analyses. This document will describe the process in which the best method to collect seated height in microgravity was developed.

    This paper outlines methods for dimensioning and tolerancing lens seats that mate with spherical lens surfaces. The two types of seats investigated are sharp corner and tangent contact. The goal is to be able to identify which seat dimensions influence lens tilt and displacement and develop a quantifiable way to assign tolerances to those dimensions to meet tilt and displacement requirements. After looking at individual seats, methods are then applied to multiple lenses with examples. All geometric dimensioning and tolerancing is according to ASME Y14.5M - 1994.

  6. A new landing impact attenuation seat in manned spacecraft biologically-inspired by felids

    Directory of Open Access Journals (Sweden)

    Yu Hui

    2015-04-01

    Full Text Available When manned spacecraft comes back to the earth, it relies on the impact attenuation seat to protect astronauts from injuries during landing phase. Hence, the seat needs to transfer impact load, as small as possible, to the crew. However, there is little room left for traditional seat to improve further. Herein, a new seat system biologically-inspired by felids’ landing is proposed. Firstly, a series of experiments was carried out on cats and tigers, in which they were trained to jump down voluntarily from different heights. Based on the ground reaction forces combined with kinematics, the experiment indicated that felids’ landing after self-initial jump was a multi-step impact attenuation process and the new seat was inspired by this. Then the construction and work process of new seat were redesigned to realize the multi-step impact attenuation. The dynamic response of traditional and new seat is analyzed under the identical conditions and the results show that the new concept seat can significantly weaken the occupant overload in two directions compared with that of traditional seat. As a consequence, the risk of injury evaluated for spinal and head is also lowered, meaning a higher level of protection which is especially beneficial to the debilitated astronaut.

    2015-09-01

    Tazobactam/piperacillin (4.5 g for adults and 90 mg/kg body weight for children, every 6 h) was administered to Japanese patients with febrile neutropenia to evaluate its defervescence and clinical efficacy and safety. The pharmacokinetics in children were also examined. Defervescence efficacy at day 4 of the treatment was achieved in 50.0% of 94 adult and 62.5% of 8 pediatric patients, respectively. The defervescence efficacy rate in relation to the neutrophil count in adults was 37.5% for the patients with a neutrophil count of less than 100/μL and 62.5% for that between 100 and 500/μL. The clinical efficacy rate at day 7 and at the end or discontinuation of the treatment was 79.6% and 59.1% in adult patients, respectively, and 57.1% and 75.0% in pediatric patients, respectively. Fifteen strains of causative bacteria were isolated in 13 adult patients at baseline. All strains were eradicated within 4 days of the treatment. The side effects that occurred in adult and pediatric patients during the treatment were all known and not specific to febrile neutropenia patients. The pharmacokinetics profiles of tazobactam/piperacillin in children with febrile neutropenia are unlikely to be different from those in children with a common bacterial infection and without any immunosuppressive conditions. The study results in Japanese patients with febrile neutropenia demonstrate that tazobactam/piperacillin treatment is efficacious and safe in adults. As for pediatric patients, given the limited number of cases studied, further investigation is needed (Clinical trial number: Japic CTI-121728).

  12. Spinal Elongation and its Effects on Seated Height in a Microgravity Environment (Spinal)

    Science.gov (United States)

    Rajulu, Sudhakar; Young, Karen

    2009-01-01

    The primary objective of this project is to provide information pertaining to changes in seated height due to spinal elongation in a microgravity environment. The proposed experiment aims to collect seated height data for subjects exposed to microgravity environments, provide information relating to seated height rate of change over time, and feed new information regarding the elongation of the spine forward into the design of Constellation systems. Historical data indicates that spinal elongation occurs when crewmembers are subjected to microgravity. In as little as two days, the typical crewmember will exhibit increases in stature of up to 3 percent. However, data has been collected only for crewmembers in standing postures, and a limited pool of subjects was available. Due to the criticality of seated height in the design of the Crew Exploration Vehicle (CEV), a better understanding of the effects of microgravity on seated height is necessary. Small changes in seated height that may not have impacted crew accommodation in previous programs will have significant effects on crew accommodation due to the layout of seats in the CEV. The proposed study will directly measure changes in seated height for crewmembers in the Shuttle cockpit. An anthropometer will be used to record measurements to the top of the head of a seated subject, and an orthogonal photograph will be taken in order to measure seated height based on scaling references of known sizes as well as verify the posture and positioning remained consistent throughout the study. Data gained from this study will provide better information to CEV designers. Accurate measurements of crew seated height will be valuable for vehicle and habitation designers for future programs as well.

    2015-02-01

    The current studies addressed the associations of classroom seating arrangements with peer status using the social relations model. Study 1 examined whether physical distance between classmates was associated with likeability and popularity. Participants were 336 children from 14 fifth- and sixth-grade classrooms (Mage=11.36 years, 47.3% boys). Children who sat closer to the center of the classroom were liked more. Moreover, classmates who sat closer together liked each other more and perceived each other as more popular. Study 2 examined whether children's likeability and popularity judgments were also reflected in the way they positioned themselves relative to their peers when they could arrange their classroom themselves. Participants were 158 children from 6 fifth- and sixth-grade classrooms (Mage=11.64 years, 50.5% boys). Participants placed liked and popular peers closer to themselves than disliked and unpopular peers. If children placed a classmate closer to themselves, they perceived that peer as better liked and more popular and were perceived as better liked and more popular in return. Implications for further research on classroom seating arrangements and peer relationships are discussed. PMID:25313926

    1998-07-01

    Providing safe, predictable, and efficient transportation for tourists to and from various venues presents a major challenge. Special-event transportation is notoriously unreliable and usually congested at peak times. The rural nature of certain tourist locations (e.g., the Grand Canyon) further complicates the problem. The proposed Intelligent Transportation Reservation System will have three components, each of which performs different functions. On-vehicle component: this component has three purposes: (1) to keep a running count of the passengers on the bus in order to determine how many additional passengers can be accommodated based on the total capacity of the vehicle; (2) through use of Global Positioning Satellite (GPS) technology, to be able to determine the location of the bus at all times; (3) to transmit information to a central data facility. Together these three features provide location, available-space, and condition information to controllers at a central data facility and to prospective riders of the bus. Kiosk component: located at every loading/unloading point, the purpose is to allow passengers-to-be to determine when the next bus (or buses) will arrive and the availability of seating. Individuals can make a reservation for the next bus with sufficient seating and will know when that bus will arrive at the kiosk. Information component: located within hotels and at venue sites, this component will provide information on the buses in the system (e.g. route and current capacity), and loading/unloading locations throughout the network at any point in time.

    International Nuclear Information System (INIS)

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)

    Sabari, Joyce; Shea, Mary; Chen, Linda; Laurenceau, Alyssa; Leung, Evan

    2016-01-01

    Wheelchair users are at high risk for developing repetitive stress injuries (RSI) of the cervical spine and glenohumeral joints due to increased demands on active range of motion (AROM) when performing functional tasks from a seated position. The addition of a seat elevation device may alleviate the risk factors that lead to the development of RSI. However, there are no studies which establish that wheelchair seat height impacts upon arthrokinematic requirements at vulnerable joints. Additionally, Medicare and most insurance carriers do not cover the cost of power seat elevators because this feature has not been shown to be a "medical necessity." This study examined differences in AROM at the cervical spine and glenohumeral joint during performance of two functional tasks while seated in a wheelchair with the seat elevation feature at minimum and maximum height. Results revealed statistically significant differences in AROM requirements for cervical extension and shoulder abduction between the two wheelchair seat heights. These findings provide preliminary support for the value of the power seat elevation function in minimizing the risk of RSI at the shoulder complex and cervical spine in wheelchair users.

    2013-03-01

    Full Text Available A wheelchair user makes direct contact with the wheelchair seat, which serves as the interface between the user and the wheelchair, for much of any given day. Seat adjustment design is of crucial importance in providing proper seating posture and comfort. This paper presents a multiple‐DOF (degrees of freedom seat adjustment mechanism, which is intended to increase the independence of the wheelchair user while maintaining a concise structure, light weight, and intuitive control interface. This four‐axis Stewart platform is capable of heaving, pitching, and swaying to provide seat elevation, tilt‐in‐space, and sideways movement functions. The geometry and types of joints of this mechanism are carefully arranged so that only one actuator needs to be controlled, enabling the wheelchair user to adjust the seat by simply pressing a button. The seat is also equipped with soft pressure‐sensing pads to provide pressure management by adjusting the seat mechanism once continuous and concentrated pressure is detected. Finally, by comparing with the manual wheelchair, the proposed mechanism demonstrated the easier and more convenient operation with less effort for transfer assistance.

    The aim of this study was to measure and analyse discomfort and biomechanics of cycling, i.e., muscle activation, centre of pressure of seat pressure profiles and pedal forces as a function of seat position. Twenty-one recreationally active individuals cycled for 10min at 100W on an ergometer cycle using five different seat positions. The neutral position was considered as basic seat position and was compared with upward, downward, forward and backward seat positions. The initial bout was repeated at the end of the recording session. Discomfort increased for upward and backward condition compared with neutral (P<0.05). Normalized surface electromyography from gastrocnemius decreased in the downward and forward position but increased in the upward and backward position. The minimum force became less negative for forward position compared with neutral seat position (P<0.05). The degree of variability of centre of pressure increased in the upward and backward position and the entropy of the centre of pressure of sitting posture for backward position decreased compared with neutral seat position (P<0.05). The present study revealed that consecutive changes of seat position over time lead to increase in discomfort as well as alterations of the biomechanics of cycling. PMID:26938676

    Cobalt based overlaying materials have been widely used as valve seat materials for high temperature and high pressure services, because of the high corrosion and wearing resistances. In nuclear power plants, however, the cobalt-based alloys would be the potential source of {sup 60}Co in the reactor water, thus alternate materials (Co-free materials) have been required and studied, especially for use as the large size valve seats on the feed water and condensate lines. From the results of a screening wearing test (sliding distance: 6 mm), some Ni-based alloys were selected as the most promising material. Then sliding tests (sliding distance: 20 mm) and mechanical tests were performed on the selected candidate alloys. In conclusion, two Ni-based alloys, that is, A-1 (10Cr-4. 5Si-0.2B-40Fe-Bal. Ni) and A-3 (10Cr-4.5Si-0.2B-40Fe-Bal.Ni) were confirmed to be useful for large size valves for high temperature and high pressure services, and the mechanical properties of both alloys were similar to those of the conventional cobalt based material.

    2016-04-01

    To promote geothermal energy use and sustainable production, the information of scaling situation from deep-seated geothermal reservoir is important. In Japan, at the Kakkonda geothermal field, Iwate prefecture, north-eastern of Japan, there is 80MW geothermal power plant using about 300 degree C fluid from the reservoir at the boundary between Quaternary Kakkonda granite and Pre-Tertiary formations about 3km depth and more deep-seated reservoir survey was carried out by NEDO. Then, to understand the mechanism of deep-seated reservoir, we survey the metal sulphide minerals deposited at production wellhead and pipeline and compare with the brine And the brine of WD-1a at 3.7km depth, into Quaternary Kakkonda granite rock. In Kakkonda geothermal system, the scales are classified into two types based on sulphide mineralogy, which are Pb-Zn rich type and Cu rich type. Pb-Zn rich scales, for example galena (PbS) and Sphalerite (ZnS), are found in Well-19 located at the marginal part of the Kakkonda granite And Cu-rich scales, for example chalcocite (Cu2S), loellingite (FeAs2) and native antimony (Sb), are found in Well-13, located at the central part of the Kakkonda granite. And the brine of WD-1a at 3.7km depth about 500 degree C, into Quaternary Kakkonda granite rock near Well-19 is rich in Pb and Zn and similar composition as the Well-19 scale. Therefore, deep reservoir of Kakkonda field evolves with mixing the fluid of shallow reservoir and the brine of occurred in the Quaternary Kakkonda granite. Then, the existence of both Pb-Zn rich scale and Cu rich scale is a characteristic feature of Kakkonda geothermal and this fact suggest to have similar zoning as found in Porphyry Copper Zoning. On progress of production the fluids from deep reservoir continue to be suffered by the fluid of shallow reservoir and meteoritic water. With temperature of production well decreasing and chemical composition changed, silica precipitation decreased and the metal sulfide mineral

  17. On the Development of Deep-Seated Landslides

    Science.gov (United States)

    Petley, D.

    2006-12-01

    Worldwide, an average of in excess of 10,000 people are killed annually by landslides. The most catastrophic of these are deep-seated rock-slope failures, which are often associated with extremely high movement rates. However, such failures are almost always preceded by comparatively long phases of creep, in which surface manifestations of the deep-seated movements are evident. This was the case at Leyte, for which local people observed the development of tension cracks prior to the final failure. Thus, the occurrence of such large-scale failures is potentially predictable, and there is thus the possibility of reducing the impact of these events. In this paper, the movement records prior to final failure for a number of large, deep-seated landslides are reviewed, including examples from the UK, Italy, Malaysia and Japan. It is shown that the patterns of movement prior to failure are surprisingly consistent across all of the examples. In particular it is shown that the three phase creep model applies to first time landslides in brittle materials. Detailed laboratory testing on undisturbed landslide materials using representative stress paths is used to explore the processes occurring within the basal regions of the landslide. Particular emphasis is placed on the tertiary phase of creep. It is shown that tertiary creep results from stress concentration during crack growth, rather from the often postulated rate and state dependent friction mechanism. It is shown that in most landslides tertiary creep is initiated when FoS=1, but the time of failure is determined by the rate at which the final phase of shear surface development can occur. Thus, lags between triggering events and final failure, as occurred at Leyte, are often due not to hydrogeological processes but rather to the time dependent nature of landslide processes. A brief consideration is also made for the potential for final failure as a result of creep rupture mechanisms in which no trigger is needed. The

    The project was implemented at the Mill Seat landfill located in the Town of Bergen, Monroe County, New York. The landfill was previously equipped with a landfill gas collection system to collect methane gas produced by the bioreactor landfill and transport it to a central location for end use. A landfill gas to energy facility was also previously constructed at the site, which utilized generator engines, designed to be powered with landfill methane gas, to produce electricity, to be utilized on site and to be sold to the utility grid. The landfill gas generation rate at the site had exceeded the capacity of the existing generators, and the excess landfill gas was therefore being burned at a candlestick flare for destruction. The funded project consisted of the procurement and installation of two (2) additional 800 KW Caterpillar 3516 generator engines, generator sets, switchgear and ancillary equipment.

    1996-12-01

    Most valves and essentially all critical service valves utilize hardfacing materials for seating and wear surfaces to minimize wear and galling. The type of hardfacing materials used, the methods of deposition, and the quality of the final product all contribute to the wear characteristics, required operating force, and life of the final product. Over the last forty years the most prevalent hardfacing materials furnished to the commercial nuclear industry consisted of cobalt base and nickel base materials. In the last several years there has been extensive development and evaluation work performed on iron base hardfacing materials. This presentation will address the wear characteristics of the various materials and the importance of consistent quality of deposited materials necessary to achieve optimum product performance and longevity.

    Full Text Available Home monitoring is a promising way to improve the quality of medical care in an ageing society. To circumvent the problem that especially demented patients may forget or be stressed by the use of medical devices at home, monitoring devices should be embedded in objects of daily life to check the patient’s health status whenever possible, without any interaction with the patient him/herself. This paper presents an intelligent toilet performing an unobtrusive health check when a person sits down. A variety of physical, electro-physical and urine parameters are analysed. This paper takes electrocardiogram and bioimpedance spectroscopy measurements and shows the practicability of measuring them on a toilet seat.

    Ablative materials are used to provide thermal protection for heat sensitive substrates against large jet fuel fires. The present investigation is concerned with the possibility to increase the available egress time for passengers, from a transport aircraft, in which the flexible polyurethane seating is exposed to the action of a large pool fire. Suitable approaches for providing sufficient ablative protection for polyurethane cushioning are considered. The efficiency of any fire blocking layer is defined as the ratio of the incident radiant heating rate, to the rate of production of combustible gas produced per unit area per second, generated by the pyrolysis of the substrate polyurethane foam. It is found that adequate fire blocking protection can be achieved through replacement of cotton batting slip covers with a wide variety of fire blocking layers. Metallized high temperature resistant char forming ablatives appear to provide optimum protection.

  4. Effect Of Vibration Amplitude Level On Seated Occupant Reaction Time

    2015-08-01

    Full Text Available The past decade has seen the rapid development of vibration comfort in the automotive industry. However little attention has been paid to vibration drowsiness. Eighteen male volunteers were recruited for this experiment. Before commencing the experiment total transmitted acceleration measured at interfaces between the seat cushion and seatback to human body was adjusted to become 0.2 ms-2 r.m.s and 0.4 ms-2 r.m.s for each volunteer. Seated volunteers were exposed to Gaussian random vibration with frequency band 1-15 Hz at two level of amplitude low vibration amplitude and medium vibration amplitude for 20-minutes in separate days. For the purpose of drowsiness measurement volunteers were asked to complete 10-minutes PVT test before and after vibration exposure and rate their subjective drowsiness by giving score using Karolinska Sleepiness Scale KSS before vibration every 5-minutes interval and following 20-minutes of vibration exposure. Strong evidence of drowsiness was found as there was a significant increase in reaction time and number of lapse following exposure to vibration in both conditions. However the effect is more apparent in medium vibration amplitude. A steady increase of drowsiness level can also be observed in KSS in all volunteers. However no significant differences were found in KSS between low vibration amplitude and medium vibration amplitude. The results of this investigation suggest that exposure to vibration has an adverse effect on human alertness level and more pronounced at higher vibration amplitude. Taken together these findings suggest a role of vibration in promoting drowsiness especially at higher vibration amplitude.

    2012-05-01

    Full Text Available Background: The seat selection and classroom dynamics may have mutual influence on the student performance and participation in both assigned and random seating arrangement. Purpose: The aim of the study was to understand the influence of seat selection on educational achievement. Methods: The seating positions of the medical students were recorded on an architectural plan during each class session and the means and standard deviations of the students’ locations were calculated in X and Y orientations. The locations of the students in the class were analyzed based on three architectural classifications: interactional zone, distance from the board, and access to the aisles. Final exam scores were used to measure the students’ educational achievement. Results: Our results demonstrate that there is a statistically significant relationship between the student's locations in the class and their attendance and educational achievements. Conclusion: Two factors may effect on educational achievement: student seating in the high interactional zone and minimal changes in seating location. Seating in the high interaction zone was directly associated with higher performance and inversely correlated with the percentage of absences. This observation is consistent with the view that students in the front of the classroom are likely more motivated and interact with the lecturer more than their classmates.

    Introduction Seat belt injuries are not uncommon. The use of seat belts is associated with a unique injury profile collectively termed “the seat belt syndrome”. The aim is to aid in the early diagnosis of seat belt injuries. Case presentation Two different patients presented to the emergency after sustaining a motor vehicle accident. Both were the drivers, restrained and had a frontal impact. On presentation they were hemodynamically stable with mild tenderness on the abdomen and the abdominal computed tomography (CT) did not show any signs of bowel or mesenteric injuries. The signs of peritonitis became obvious after 24 h in one case and after 3 days in the other. Discussion Early diagnosis provides better outcomes for patients with seat belt injuries, but this remains a challenge to trauma surgeons. The typical findings of peritonitis might not be present initially. The presence of abdominal wall ecchymosis (seat belt sign) increases the chance of intraabdominal injuries by eight folds. Conclusion Clinical signs of intestinal injuries might not be obvious on presentation. In the presence of seat belt sign the possibility of bowl injury must be suspected. Admit the patient for observation even if no clinical or radiological findings are present at presentation. PMID:26826929

    The benefit of wearing a rear seatbelt in reducing the risk of motor vehicle crash-related fatalities and injuries has been well documented in previous studies. Wearing a seatbelt not only reduces the risk of injury to rear-seat passengers, but also reduces the risk of injury to front-seat occupant who could be crushed by unbelted rear-seat passengers in a motor vehicle crash. Despite the benefits of wearing a rear seatbelt, its rate of use in Malaysia is generally low. The objective of this study was to identify factors that are associated with the wearing of a seatbelt among rear-seat passengers in Malaysia. Multinomial logistic regression analysis of the results of a questionnaire survey of 1651 rear-seat passengers revealed that rear-seat passengers who were younger, male, single and less educated and who had a perception of a low level of legislation enforcement, a lower risk-aversion and less driving experience (only for passengers who are also drivers) were less likely to wear a rear seatbelt. There was also a significant positive correlation between driver seatbelt and rear seatbelt-wearing behaviour. This implies that, in regards to seatbelt-wearing behaviour, drivers are more likely to adopt the same seatbelt-wearing behaviour when travelling as rear-seat passengers as they do when driving. These findings are crucial to the development of new interventions to increase the compliance rate of wearing a rear seatbelt. PMID:22633252

    Despite the reported health-related advantages of the use of warm water in bidets, there are health-related disadvantages associated with the use of these toilet seats, and the bacterial research is sparse. We conducted a survey on the hygienic conditions of 127 warm-water bidet toilet seats in restrooms on a university campus. The spray water from the toilet seats had less residual chlorine than their tap water sources. However, the total viable microbial count was below the water-quality standard for tap water. In addition, the heat of the toilet seats' warm-water tanks caused heterotrophic bacteria in the source tap water to proliferate inside the nozzle pipes and the warm-water tanks. Escherichia coli was detected on the spray nozzles of about 5% of the toilet seats, indicating that the self-cleaning mechanism of the spray nozzles was largely functioning properly. However, Pseudomonas aeruginosa was detected on about 2% of the toilet seats. P. aeruginosa was found to remain for long durations in biofilms that formed inside warm-water tanks. Infection-prevention measures aimed at P. aeruginosa should receive full consideration when managing warm-water bidet toilet seats in hospitals in order to prevent opportunistic infections in intensive care units, hematology wards, and other hospital locations.

    Few statistical models of rear seat passenger posture have been published, and none has taken into account the effects of occupant age. This study developed new statistical models for predicting passenger postures in the rear seats of automobiles. Postures of 89 adults with a wide range of age and body size were measured in a laboratory mock-up in seven seat configurations. Posture-prediction models for female and male passengers were separately developed by stepwise regression using age, body dimensions, seat configurations and two-way interactions as potential predictors. Passenger posture was significantly associated with age and the effects of other two-way interaction variables depended on age. A set of posture-prediction models are presented for women and men, and the prediction results are compared with previously published models. This study is the first study of passenger posture to include a large cohort of older passengers and the first to report a significant effect of age for adults. The presented models can be used to position computational and physical human models for vehicle design and assessment. Practitioner Summary: The significant effects of age, body dimensions and seat configuration on rear seat passenger posture were identified. The models can be used to accurately position computational human models or crash test dummies for older passengers in known rear seat configurations.

  13. Advances in examining preferences for similarity in seating: Revisiting the aggregation index.

    Hernandez, Ivan

    2015-12-01

    Past research finds that people prefer to sit next to others who are similar to them in a variety of dimensions such as race, sex, and physical appearance. This preference for similarity in seating arrangements is called aggregation and is most commonly measured with the aggregation index (Campbell, Kruskal, & Wallace, Sociometry 29, 1-15, 1966). The aggregation index compares the observed dissimilarity in seating with the amount of dissimilarity that would be expected if seats were chosen randomly. However, the current closed-form equations for this method limit the ease, flexibility, and inferences that researchers have. This paper presents a new approach for studying aggregation that uses bootstrapped resampling of the seating environment to estimate the aggregation index parameters. This method, compiled as an executable program, SocialAggregation, reads a seating chart matrix provided by the researcher and automatically computes the observed number of dissimilar adjacencies, and simulates random seating preferences. The current method's estimates not only converge with those of the original method, but it also handles a wider variety of situations and also allows for more precise hypothesis testing by directly modeling the distribution of the seating arrangements. Developing a better measure of aggregation opens new possibilities for understanding intergroup biases, and allows researchers to examine aggregation more efficiently. PMID:25427955

  14. Using a pneumatic support to correct sitting posture for prolonged periods: a study using airline seats.

    McGill, Stuart M; Fenwick, Chad M J

    2009-09-01

    Prolonged sitting with spine flexion has been linked to low back disorders. A variety of mechanisms account for this based on biomechanical and neurological variables. Airline seats typically cause pronounced lumbar flexion due to their hollowed seat back design. A pneumatic support, placed between the seat back and the lumbar spine, was tested to see if lumbar flexion was reduced. Results showed that when the seats were positioned in the upright position, 15 of 20 participants experienced reduced lumbar flexion (by 15 degrees on average) with the support. The study was repeated on the five non-responders with the seatback set in the reclined position. This resulted in another four experiencing less lumbar flexion. Since seated flexion is associated with disc stress, reducing flexion with the support reduced lumbar stress. Spine flexion that results from prolonged sitting is associated with disc stress and pain. The pneumatic support tested here reduced spine flexion. While it is not known why airline seats are designed with no lumbar support, which causes excessive lumbar flexion while seated, the pneumatic support corrected this deficit. Reclining the seatback enhanced this effect.

    Full Text Available Sheryl Strasser1, Laurie Whorton2, Amanda J Walpole3, Sarah Beddington11Institute of Public Health, Partnership for Urban Health Research, Georgia State University, Atlanta, GA, USA; 2WellStar Corporate and Community Health, Marietta, GA, USA; 3Cobb and Douglas Public Health, Marietta, GA, USAIntroduction: The leading cause of injury and death among children in the United States is motor vehicle crashes. Even though restraint laws are in place and public awareness campaigns and educational interventions have increased, many children are still improperly restrained or not restrained at all. When correctly used, child restraints significantly reduce risk of injury or death.Methods: The purpose of the study was to elicit caregiver baseline knowledge of car seat installation and regulation before receiving car seat education from certified technicians at Inspection Station events. Inspection Station is a program whereby staff assists parents in correctly positioning car seats in participants’ vehicles. Over an 8-week period, Safe Kids Cobb County Car Seat Technicians distributed a 16-item survey, with 10 knowledge-based questions and six demographic questions to Inspection Station participants. Descriptive statistics and t-tests were conducted to assess relationships between participant age, ethnicity, and gender with overall knowledge scores. Regression analysis was run to determine the association between participant education level and total child restraint knowledge.Results: One hundred sixty-nine surveys were completed. Participant knowledge of vehicular child restraint ranged from 0% to 90% on all items. Only 29.6% of caregivers understood the proper tightness of the harness system. Less than half of the caregivers (43.8% were aware of the Georgia law requiring children aged 6 years and younger to be in some type of child restraint. Only 43.2% of caregivers surveyed knew that children need to ride in a rear-facing child restraint until 1

    2016-01-01

    Full Text Available The automotive seat headrest plays an important role in the passenger protection during car crashes, and its structure parameters and performance have direct influence on the seat crashworthiness. In this paper, according to relevant regulations of GB11550-2009, collision simulation analyses of the seat headrest structure were carried out by Ls-dyna code. The law of different headrest packaging parameters on collision energy absorption was investigated to provide guidance for the headrest structure optimization design and improvement. The research results show that, with the increase of packaging of the headrest, the maximum acceleration and high acceleration duration time of head gradually decreases.

    Because of the difficulties of describing the process of combustion of underground mine fires, usually the fire seat is considered as a fixed point in the methods of mine fire computer simulation, however this is not in keeping with the feature of the distribution of the combustibles and the process of combustion in mine fires. A conception about movable linear fire seat is put forward first by the authors, together with the calculated models of the thermal decomposition rate, flame spreading velocity and the steady burning length of a linear fire seat etc. The paper also introduces the results of the application of these models.

  10. Study on smart seat technology for railroad vehicles using piezoelectric sensors

    International Nuclear Information System (INIS)

    A study on smart seats for railroad vehicles was conducted using piezoelectric (PZT) sensors. For this purpose, the concept of passenger friendly smart seats was defined, and a PZT sensor was selected as the optimum sensor based on this concept. Using PZT sensors, simulation tests were performed using a sub-scale model railroad vehicle. In these tests, the main functions of the smart seats were extracted and simplified to improve the effectiveness of the simulation tests. Based on the test results, the system for smart seats proposed in this paper was successfully verified using PZT sensors and the dedicated operation software for the system. This paper will contribute to the improvement of services in high-speed rail systems through advances in ticket checking tasks.

  13. Using Failure Mode and Effects Analysis to design a comfortable automotive driver seat.

    Science.gov (United States)

    Kolich, Mike

    2014-07-01

    Given enough time and use, all designs will fail. There are no fail-free designs. This is especially true when it comes to automotive seating comfort where the characteristics and preferences of individual customers are many and varied. To address this problem, individuals charged with automotive seating comfort development have, traditionally, relied on iterative and, as a result, expensive build-test cycles. Cost pressures being placed on today's vehicle manufacturers have necessitated the search for more efficient alternatives. This contribution aims to fill this need by proposing the application of an analytical technique common to engineering circles (but new to seating comfort development), namely Design Failure Mode and Effects Analysis (DFMEA). An example is offered to describe how development teams can use this systematic and disciplined approach to highlight potential seating comfort failure modes, reduce their risk, and bring capable designs to life.

    Custom wheelchair seats can be used to help prevent pressure ulcers in individuals with spinal cord injury. In this study, a strap-based system was evaluated in three Veterans with spinal cord injury. Interface pressure distributions were measured after transfers, wheeling, and pressure relief maneuvers and after fittings by three different therapists. We found that pressure distribution measures were not generally affected after transfers and wheeling using the strap-based wheelchair and that pressure relief maneuvers were able to be performed. Additionally, all therapists were able to customize the wheelchair seat to clinically acceptable levels in 4 to 40 min for the three subjects. Future studies can test the long-term effects of using the strap-based wheelchair seat and identifying individuals that would most benefit from a rapidly customizable wheelchair seat. PMID:25626113

    2016-04-01

    Typhoon Morakot brought huge amount of rainfall to the southern Taiwan in 2009 and caused severe landslides and debris flow hazard. After Typhoon Morakot, it was found that the volume of sediment transported by the debris flow and its effects on the affected area were much more significant compared to previous case history, which may due to the huge amount of rainfall causing significant deep-seated landslides in the basin. In this study, the effects and tendency of the sediment transportation in a river basin following deep-seated landslides caused by typhoon Morakot were evaluated. We used LiDAR, DEM, and aerial photo to identify characteristics of deep-seated landslides in a debris flow river basin, KSDF079 in Liuoguey District, Kaohsiung City, Taiwan. Eight deep-seated landslides were identified in the basin. To estimate the potential landslide volume associated with the deep-seated landslides, the stability analysis was conducted to locate the critical sliding surface, and the potential landside volume was estimated based on the estimation equation proposed by the International Geotechnical Societies' UNESCO Working Party on World Landslide Inventory (WP/WLI, 1990). The total potential landslide volume of the eight deep-seated landslides in KSDF079 basin was about 28,906,856 m3. Topographic analysis was performed by using DEM before and LiDAR derived DEM after typhoon Morakot to calculate the landslide volume transported. The result of erosion volume and deposition volume lead to a run out volume of 5,832,433 m3. The results appeared to consist well with the field condition and aerial photo. Comparing the potential landslide volume and run out volume of eight deep-seated landslides, it was found that the remaining potential landslide volume was about 80%. Field investigation and topographic analysis of the KSDF079 debris flow revealed that a significant amount of sediment deposition remained in the river channel ranging from the middle to the downstream

  20. Experimental and Numerical Investigation of the Dynamic Seat Comfort in Aircrafts

    Science.gov (United States)

    Ciloglu, Hakan

    This research focuses on the dynamic seat comfort in aircrafts specifically during takeoff, landing and cruise through turbulence flight conditions. The experiments are performed using a multi axis shaker table in the Automotive Centre of Excellence (ACE) at the University of Ontario Institute of Technology subjected to sample takeoff, landing and cruise vibration recordings obtained onboard of an actual flight. The input vibrations introduced to the aircraft seats during actual flight conditions and during the experiments in the ACE are compared and it is concluded that the given flight conditions were successfully replicated for the interest of this thesis. The experiments are conducted with two different aircraft seats, economy class and business class. Furthermore, to investigate the importance of seat cushion characteristics in addition to economy and business class seat cushions, three laboratory made cushions were included in the investigation as well. Moreover, the effect of passenger weight is also discussed by conducting the experiments with 1 and 2 identical dummies. It is concluded that static seat properties play a significant role in the comfort perception level as well as flight conditions. Among the three flight condition, landing appeared to be the most uncomfortable case comparing to takeoff and cruise. In addition to experimental work, a numerical study to simulate the flight conditions is undertaken with the initial work of CAD modelling. The simulated responses of the seat is partially matching with experimental results due to unknown parameters of the cushion and the connections of the aircraft seat that cannot be created in the CAD model due to unknown manufacturing processes.

    Wininger, Michael; Crane, Barbara A

    2015-01-01

    Pressure mapping is a frequently used tool with great power to provide information about the forces between a patient and a wheelchair seat. One widely recognized limitation to this paradigm is the possibility of data loss due to sensor saturation. In this study, we seek to quantify and describe the saturation observed in the measurement of interface pressures of wheelchair users. We recorded approximately two minutes of interface pressure data from 22 elderly wheelchair users (11M/11F, 80 ± 10 years) and found that 4.7% of data frames had 1 saturated sensor, and 9.0% had more than one saturated sensor, for a total of 13.7% of all frames of data. Data from three of the 22 subjects (13.6%) were substantially affected by the persistent presence of saturated sensors. We conclude that for this population of elderly wheelchair users, sensor saturation may be a concern and should be factored properly into study design a priori.

    An aircraft seat manufacturing company requested a NIOSH health hazard evaluation to help identify a strong odor that had persisted throughout the facility for over a year. Employees reported experiencing health effects thought to be related to the odor. We collected and analyzed area air samples for volatile organic compounds, endotoxin, bacterial and fungal metagenome, and metalworking fluid aerosol. Bulk metalworking fluid samples were analyzed for endotoxin, bacterial and fungal metagenome, and viable bacteria and fungus. We also evaluated the building ventilation systems and water diversion systems. Employees underwent confidential medical interviews about work practices, medical history, and health concerns. Based on our analyses, the odor was likely 2-methoxy-3,5-dimethylpyrazine. This pyrazine was found in air samples across the facility and originated from bacteria in the metalworking fluid. We did not identify bacteria known to produce the compound but bacteria from the same Proteobacteria order were found as well as bacteria from orders known to produce other pyrazines. Chemical and biological contaminants and odors could have contributed to health symptoms reported by employees, but it is likely that the symptoms were caused by several factors. We provided several recommendations to eliminate the odor including washing and disinfecting the metalworking machines and metalworking fluid recycling equipment, discarding all used metalworking fluid, instituting a metalworking fluid maintenance program at the site, and physically isolating the metalworking department from other departments.

In this paper the influence of tractor seat height above the ground on the lateral vibrations to which the tractor driver is exposed is studied by means of a geometrical and an experimental analysis. Both analyses show that: (i lateral vibrations experienced by a tractor driver increase linearly with tractor-seat height above the ground; (ii lateral vibrations to which the tractor driver is exposed can equal or exceed vertical vibrations; (iii in medium-size tractors, a feasible 30 cm reduction in the height of the tractor seat, which represents only 15% of its current height, will reduce the lateral vibrations by around 20%; and (iv vertical vibrations are scarcely influenced by tractor-seat height above the ground. The results suggest that manufacturers could increase the comfort of tractors by lowering tractor-seat height above the ground, which will reduce lateral vibrations.

    New technologies have led to an increasingly sedentary lifestyle. Sedentary behaviour is characterised by physical inactivity and is associated with several health risks. This excessive sitting does not only take place in the office or at home, but also during daily commute. Therefore, BMW AG developed an active seating system for the back seat of a car, consisting of sensors in the back rest that register upper body movements of the passenger, with which the passenger controls a game. This study evaluated three different aspects of active seating compared to other tasks (reading, working on laptop, and gaming on tablet). First, discomfort and comfort perception were measured in a 30-minute driving test. Discomfort was very low for all activities and participants felt significantly more challenged, more fit and more refreshed during active seating. Second, heart rate was measured, indicating a light intensity, but nevertheless non-sedentary, activity. Third, average and variability in activity of six postural muscles was measured by electromyography (EMG), showing a higher muscle activity and higher muscle variability for active seating compared to other activities. Active seating might stimulate movements, thereby increasing comfort and well-being. PMID:25479990

    2012-01-01

    Crashworthy seat structure with considerable energy absorption capacity is a key component for aircraft to improve its crashworthiness and occupant survivability in emergencies. According to Federal Aviation Administration(FAA) regulations, seat performance must be certified by dynamic crash test which is quite expensive and time-consuming. For this reason, numerical simulation is a more efficient and economical approach to provide the possibility to assess seat performances and predict occupant responses. A numerical simulation of the crashworthy seat structure was presented and the results were also compared with the full-scale crash test data. In the numerical simulation, a full-scale three-dimensional finite element model of the seat/occupant structure was developed using a nonlinear and explicit dynamic finite element code LS-DYNA3D. Emphasis of the numerical simulation was on predicting the dynamic response of seat/occupant system,including the occupant motion which may lead to injuries,the occupant acceleration-time histories, and the energy absorbing behavior of the energy absorbers. The agreement between the simulation and the physical test suggestes that the developed numerical simulation can be a feasible substitute for the dynamic crash test.

    2014-01-01

    Full Text Available This study presents a Child Video Dataset (CVDS that has numerous videos of different ages and situation of children. To simulate a babysitter’s vision, our application was developed to track objects in a scene with the main goal of creating a reliable and operative moving child-object detection system. The aim of this study is to explore novel algorithms to track a child-object in an indoor and outdoor background video. It focuses on tracking a whole child-object while simultaneously tracking the body parts of that object to produce a positive system. This effort suggests an approach for labeling three body sections, i.e., the head, upper and lower sections and then for detecting a specific area within the three sections and tracking this section using a Gaussian Mixture Model (GMM algorithm according to the labeling technique. The system is applied in three situations: Child-object walking, crawling and seated moving. During system experimentation, walking object tracking provided the best performance, achieving 91.932% for body-part tracking and 96.235% for whole-object tracking. Crawling object tracking achieved 90.832% for body-part tracking and 96.231% for whole object tracking. Finally, seated-moving-object tracking achieved 89.7% for body-part tracking and 93.4% for whole-object tracking.

    International Nuclear Information System (INIS)

    The author proposes an overview of methods and concepts used in the nuclear industry, at the design level as well as at the exploitation level, to ensure an acceptable safety level, notably in the case of nuclear reactors. He first addresses the general objectives of nuclear safety and the notion of acceptable risk: definition and organisation of nuclear safety (relationships between safety authorities and operators), notion of acceptable risk, deterministic safety approach and main safety principles (safety functions and confinement barriers, concept of defence in depth). Then, the author addresses the safety approach at the design level: studies of operational situations, studies of internal and external aggressions, safety report, design principles for important-for-safety systems (failure criterion, redundancy, failure prevention, safety classification). The next part addresses safety during exploitation and general exploitation rules: definition of the operation domain and of its limits, periodic controls and tests, management in case of incidents, accidents or aggressions

    Safety culture has become a topic of increasing interest for industry and regulators as issues are raised on safety problems around the world. The keys to safety culture are organizational effectiveness, effective communications, organizational learning, and a culture that encourages the identification and resolution of safety issues. The necessity of a strong safety culture places an onus on all of us to continually question whether the safety measures already in place are sufficient, and are being applied. (author)

  5. Child care and other support programs.

    2013-01-01

    The U.S. military has come to realize that providing reliable, high-quality child care for service members' children is a key component of combat readiness. As a result, the Department of Defense (DoD) has invested heavily in child care. The DoD now runs what is by far the nation's largest employer-sponsored child-care system, a sprawling network with nearly 23,000 workers that directly serves or subsidizes care for 200,000 children every day. Child-care options available to civilians typically pale in comparison, and the military's system, embedded in a broader web of family support services, is widely considered to be a model for the nation. The military's child-care success rests on four pillars, write Major Latosha Floyd and Deborah A. Phillips. The first is certification by the military itself, including unannounced inspections to check on safety, sanitation, and general compliance with DoD rules. The second is accreditation by nationally recognized agencies, such as the National Association for the Education of Young Children. The third is a hiring policy that sets educational and other requirements for child-care workers, and the fourth is a pay scale that not only sets wages high enough to discourage the rapid turnover common in civilian child care but also rewards workers for completing additional training. Floyd and Phillips sound a few cautionary notes. For one, demand for military child care continues to outstrip the supply In particular, as National Guard and Reserve members have been activated during the wars in Iraq and Afghanistan, the DoD has sometimes struggled to provide child care for their children. And force reductions and budget cuts are likely to force the military to make difficult choices as it seeks to streamline its child-care services in the years ahead. PMID:25518693

    Conclusion The Swedish Eating Assessment Tool (S-EAT-10) is a reliable and valid self-administered tool in assessment of dysphagia in adult Swedish patients with high internal consistency, reliability, and discriminative validity. The normative data show that a score of 3 or more is abnormal. S-EAT-10 is recommended to be used in preliminary diagnostics of dysphagia. Objective To translate and adapt the EAT-10 for use in the Swedish patient population, and to present norms and measures of discriminative validity and reliability of a Swedish version of the Eating Assessment Tool-10 (S-EAT-10). Methods Prospective consecutive clinical study. In total, 134 community-dwelling adult respondents/controls without dysphagia completed the S-EAT-10, as did 119 patients referred for fiberendoscopic evaluation of swallowing at Karolinska University Hospital, Stockholm, Sweden. Patient vs control status was used as the criterion for discriminative validity assessment by logistic regression analysis. Results The mean S-EAT-10 score was 0.2 (range = 0-3) for controls and 18 (range = 0-38) for patients. Based on a cut-off score of ≥ 3 which was considered to be reflective of abnormalities, sensitivity was 98.5% and specificity 94.1%. Internal consistency reliability was high (Cronbach's alpha = 0.88), as was test-re-test reliability (ICC = 0.90).

    2008-04-01

    Although much research has been devoted to constructing specific models or to measuring the response characteristics of seated subjects, investigations on a mathematical human model on a seat with a backrest to evaluate vehicular riding comfort have not yet attracted the same level of attention. For the responses of a seated body to vertical vibrations, mathematical models of the mechanisms must be at least two-dimensional in the sagittal plane. In describing the motions of a seated body, two multibody models representative of the automotive postures found in the literature were investigated, one with and the other without a backrest support. Both models were modified to suitably represent the different automotive postures with and without backrest supports, and validated by various experimental data from the published literature pertaining to the same postural conditions. On the basis of the analytical study and the experimental validation, the fourteen-degrees-of-freedom model proposed in this research was found to be best fitted to the test results; therefore, this model is recommended for studying the biodynamic responses of a seated human body exposed to vertical vibrations in various automotive postures.

  9. Can pelvis angle be monitored from seat support forces in healthy subjects?

    2009-03-01

    Individuals who cannot functionally reposition themselves often need dynamic seating interventions that change body posture from automatic chair adjustments. Pelvis alignment directly affects sitting posture, and systems that adjust and monitor pelvis angle simultaneously might be applicable to control body posture in sitting. The present study explores whether it is feasible to monitor pelvis angle from seat support forces. Pelvis angle estimation was based on equivalent "two-force member" loading for which pelvis orientation equals the orientation of the equivalent contact force. Theoretical evaluation was done to derive important conditions for practical application. An instrumented wheelchair was developed for experimental validation in healthy subjects. Seat support forces were measured, and mechanical analysis was done to derive the equivalent contact force from which we estimated the pelvis angle. Model analysis showed a significant influence of pelvis mass, hip force, and lumbar torque on the relation between the actual pelvis angle and the predicted pelvis angle. Proper force compensation and minimal lumbar torque seemed important for accurate pelvis angle estimations. Experimental evaluation showed no body postures that involved a clear relation between the pelvis angle and the orientation of the equivalent contact force. Findings suggest that pelvis angle could not be estimated in healthy individuals under the described experimental seating conditions. Validation experiments with impaired individuals must be performed under different seating conditions to provide a better understanding whether the principle is of interest for clinical application.

    2011-06-01

    Full Text Available Seat vibration is one of the major causes of discomfort in moving vehicle. Tyre, engine, drivetrain and aerodynamic forces excite the cabin and interior through various pathways. In this paper, the contributions of tyre and engine vibration to seat excitations are studied. Virtual Source Analysis (VSA is implemented to decompose the source signals into incoherent phenomena. Studying these phenomena (virtual sources shows the amount and frequency bands that physical sources affect the seat vibration as the response channel. Experiment is conducted while riding on smooth and bumpy roads. Road roughness is characterized using International Roughness Index (IRI. VSA technique approve that tyre is the main source of seat vibration for the moving vehicle. Seat vibration has significant values below 400 Hz and tyre is found to be the dominant source of excitations for both smooth and bumpy roads. For smooth road, strong engine harmonics below 200 Hz also has some involvements. But in bumpy road, tyre vibration rise up and become the dominant broadband source of excitations. Tyre damper and engine mount Frequency Response Function (FRF analysis show that these parts are designed to be highly efficient below 1400 Hz and 200 Hz, respectively. These ranges are identical with those that were found as the critical operational frequency spans in VSA.

    2016-03-01

    To improve the riding comfort and rational utilization of the electrical energy captured by an automotive thermoelectric generator (ATEG), a temperature-controlled car seat was constructed to adjust the temperature of the car seat surface. Powered by the ATEG and the battery, the seat-embedded air conditioner can improve the riding comfort using a thermoelectric device to adjust the surface temperature of the seat, with an air duct to regulate the cold side and hot side of the thermoelectric device. The performance of the thermoelectric cooler (TEC) and theoretical analysis on the optimum state of the TEC device are put forward. To verify the rationality of the air duct design and to ensure sufficient air supply, the velocity field of the air duct system was obtained by means of the finite element method. To validate the reliability of the numerical simulation, the air velocity around the thermoelectric device was measured by a wind speed transmitter. The performance of the temperature-controlled car seat has been validated and is in good agreement with bench tests and real vehicle tests.

    2016-09-01

    The objective of this study was to evaluate how different workstations may influence physical behavior in office work through motion and how that may affect spinal loads and discomfort. Twenty subjects performed a typing task in three different workstations (seated, standing, and perching) for one hour each. Measures of postural transitions, spinal loads, discomfort, and task performance were assessed in order to understand the effects of workstation interaction over time. Results indicated that standing had the most amount of motion (6-8 shifts/min), followed by perching (3-7 shifts/min), and then seating (seating the least. However, spinal loads were highest in A/P shear during standing (190N posterior shear, 407N anterior shear) compared to perching (65N posterior shear, 288N anterior shear) and seating (106N posterior shear, 287 anterior shear). These loads are below the risk threshold for shear, but may still elicit a cumulative response. Perching may induce motion through supported mobility in the perching stool, whereas standing motion may be due to postural discomfort. Office workstation designs incorporating supported movement may represent a reasonable trade-off in the costs-benefits between seating and standing. PMID:27184325

    This manuscript reports the results of an evaluation of two community-based booster seat promotion programs in Michigan; one program focused on a low-income community, while the other focused on a Hispanic community. Each community received funding to develop and implement a booster seat intervention program specific to their community. To determine the effectiveness of each program, direct observation surveys of booster seat use were conducted in each community, as well as in similarly composed comparison communities, before and after program implementation. A process evaluation documented activities and provided additional information for interpreting the results of the direct observation survey. Target age children (4-8 years) were observed traveling in cars, vans/minivans, sport-utility vehicles, and pickup trucks in each community. Baseline booster seat use was 19.0+/-5.3% and 9.7+/-2.5% for the low-income and Hispanic program communities, respectively. Post program results showed no significant change for the low-income program community, and a significant increase within the Hispanic program community. The process evaluation revealed challenges for each program and suggestions to overcome those challenges. Findings from the study can be useful to other communities interested in implementing programs to increase the use of booster seats. PMID:18215561

    2016-09-01

    In this study, the effect of strapping rowers to their sliding seat on performance during 75 m on-water starting trials was investigated. Well-trained rowers performed 75 m maximum-effort starts using an instrumented single scull equipped with a redesigned sliding seat system, both under normal conditions and while strapped to the sliding seat. Strapping rowers to their sliding seat resulted in a 0.45 s lead after 75 m, corresponding to an increase in average boat velocity of about 2.5%. Corresponding effect sizes were large. No significant changes were observed in general stroke cycle characteristics. No indications of additional boat heaving and pitching under strapped conditions were found. The increase in boat velocity is estimated to correspond to an increase in average mechanical power output during the start of on-water rowing between 5% and 10%, which is substantial but smaller than the 12% increase found in a previous study on ergometer starting. We conclude that, after a very short period of adaptation to the strapped condition, single-scull starting performance is substantially improved when the rower is strapped to the sliding seat.

    Low cost alternatives have been sought to provide motion cues in ground-based flight simulators to meet mission objectives. The ability to provide high frequency vibrations makes the dynamic seat attractive to helicopter training applications. Previous studies have found that dynamic seat does enhance the realism of the cockpit and affect pilots' workload. This investigation, conducted under the auspices of the Joint Shipboard Helicopter Integration Process (JSHIP), is using a three degree-of-freedom dynamic seat, i.e., heave, surge, and sway, with limited travels in a research simulator configured as a UH-60 Black Hawk at NASA Ames Research Center. The seat's effectiveness is studied using hover, landing, pirouette, bob-up/bob-down, sidestep, and acceleration/deceleration maneuvers. Seat commands consist of constant vibrations in heave and sway which provide the fundamental vibratory cues. Pilot station accelerations and collective controls provide onset and sustained commands. In addition, transient effects due to translational-lift, collective; and normal acceleration are produced by regulating the magnitude and frequency that depend on the rotor rpm. Results are compared to flight test data and two other ground-based motion systems configurations, i.e., a motion condition with very large motion travels and a motion condition that is comparable with commercial simulator travels. Both subjective and objective data will be analyzed to determine the significance of the motion cueing effect in each system for selected maneuvers.

  16. STUDY ON VARIATION OF SETTING AND STOPPING PRESSURES OF SAFETY VALVE WITH STRUCTURAL MODIFICATION

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The possibility of pressure control with the structural change of a safety valve is investigated. Safety valve is commonly used as safety devices for numerous applications which include boilers,ships,industrial plants,and piping.Setting and stopping pressures of a safety valve,pset and psto,are traditionally adjusted with a fine tuning of seat ring and valve ring heights, hsr and hvr. However, it is not easy to achieve the proper setting and stopping pressures of a safety valve in practice. The depth of inside and outside grooves in a valve, di and do are modified and their effects on setting and stopping pressures of a safety vlave are tested. The most appropriate values appear 1.0 mm in di and 0.5~1.0 mm in do,respectively. The valve ring height, hvr,shows that the best results can be achieved at 2.3 mm for setting pressures of 0.1~0.4 MPa and 1.0 mm for setting pressures of 0.5~1.0 MPa. The stopping pressures increases with the increase of seat ring height,hsr, upto certain hsr value and then becomes independent to the seat ring height. This implies that there exists the optimum hsr,which provides the largest flow rate and the proper stopping pressure. Stopping pressures of a safety valve are adjusted with the seat ring and valve ring heights. This study,however,demonstrated that the modification of value grooves also changes setting and stopping pressures of a safety valve.Therefore,the proper selection in dimensions of the inside and outside grooves should be considered for the safety valve design.

    The Convention concerning the Prohibition and Immediate Action for the Elimination of the Worst Forms of Child Labour was adopted by the International Labour Organization in 1999. 174 countries around the world have signed or ratified the convention, which requires countries to adopt laws and implement programs to prohibit and eliminate child labor that poses harms to health or safety. Nonetheless, child labor continues to be common in the agriculture and mining sectors, where safety and environmental hazards pose significant risks. Drawing upon recent human rights investigations of child labor in tobacco farming in Kazakhstan and gold mining in Mali, the role of international human rights mechanisms, advocacy with government and private sector officials, and media attention in reducing harmful environmental exposures of child workers is discussed. Human rights-based advocacy in both cases was important to raise attention and help ensure that children are protected from harm.

  20. Semi-active variable stiffness vibration control of vehicle seat suspension using an MR elastomer isolator

    International Nuclear Information System (INIS)

    This paper presents a study on continuously variable stiffness control of vehicle seat suspension using a magnetorheological elastomer (MRE) isolator. A concept design for an MRE isolator is proposed in the paper and its behavior is experimentally evaluated. An integrated seat suspension model, which includes a quarter-car suspension and a seat suspension with a driver body model, is used to design a sub-optimal H∞ controller for an active isolator. The desired control force generated by this active isolator is then emulated by the MRE isolator through its continuously variable stiffness property when the actuating condition is met. The vibration control effect of the MRE isolator is evaluated in terms of driver body acceleration responses under both bump and random road conditions. The results show that the proposed control strategy achieves better vibration reduction performance than conventional on–off control

    The purpose of this study was to determine if the advantages and disadvantages of a new automotive seating concept, known as the micro-adjuster control system, could be reliably evaluated using both a physiological assessment technique (i.e., electromyography [EMG]) and a subjective questionnaire. The results indicate that psychophysical measures of discomfort and the root mean squared (RMS) activity of the EMG are statistically related, r (8) = -.788, p =.020. More specifically, subjective perceptions of comfort were found to improve with decreasing levels of muscle activity. This implies that seat comfort can be evaluated on the basis of physiological as well as subjective responses to prolonged driving. This finding should drastically improve automobile seat design efforts.

  3. Seating Arrangement, Group Composition and Competition-driven Interaction: Effects on Students' Performance in Physics

    International Nuclear Information System (INIS)

    We probe the effect of seating arrangement, group composition and group-based competition on students' performance in Physics using a teaching technique adopted from Mazur's peer instruction method. Ninety eight lectures, involving 2339 students, were conducted across nine learning institutions from February 2006 to June 2009. All the lectures were interspersed with student interaction opportunities (SIO), in which students work in groups to discuss and answer concept tests. Two individual assessments were administered before and after the SIO. The ratio of the post-assessment score to the pre-assessment score and the Hake factor were calculated to establish the improvement in student performance. Using actual assessment results and neural network (NN) modeling, an optimal seating arrangement for a class was determined based on student seating location. The NN model also provided a quantifiable method for sectioning students. Lastly, the study revealed that competition-driven interactions increase within-group cooperation and lead to higher improvement on the students' performance.

    2014-01-01

    Digital Displacement (DD) fluid power machines utilizes electronically controlled seat valves connected to pressure chambers to obtain variable displacement with high operational efficiency and high bandwidth. To achieve high efficiency, fast valve switching is essential and all aspects related...... to the dynamic behaviour of the seat valves must be considered to optimize the machine efficiency. A significant effect influencing the valves switching performance is the presence of oil stiction when separating the contact surfaces in valve opening movement. This oil stiction force is limited by cavitation...... for low pressure levels, e.g. valves connected to the low pressure manifold, however for valves operated at higher pressure levels, the oil stiction force is dominating when the separating surfaces are close to contact. This paper presents an analytic solution to the oil stiction force for annular seat...

This article reviews what we know about the functional impact of adaptive seating interventions - a common assistive technology type recommended for children with CP. A contemporary assistive technology outcomes framework is considered as a way to model the temporality and measure the effects of seating interventions and moderating cofactors. Three research studies are profiled to illustrate different research methods, measurement approaches, and follow-up periods to learn about adaptive seating outcomes. Recommendations for future research include the adoption of common measurement indicators, consideration of quality assessment criteria, and the use of varied methodologies to generate new knowledge about functional outcomes. It is suggested that the proposed strategies will lead to new understandings, clinical applications, and ultimately improvements in the everyday lives of children with CP and their families.

    2013-01-01

    Digital Displacement Fluid Power is an upcoming technology setting new standards for the achievable efficiency of fluid power pumps and motors. The core element of the Digital Displacement technology is high performance electronically controlled seat valves, which must exhibit very low flow...... pressure loss and switching times within a few milliseconds to enable high efficiency operation. These valves are mechatronic components and special attention to both the mechanical, electromagnetic, fluid dynamical and control system design must be paid to ensure the needed performance. In the present...... work an annular seat valve suitable for use in Digital Displacement units is considered, and the ring geometry is optimized using finite element analysis including non-linear material behaviour, contact elements and fluid pressure penetrating load, closely reflecting the actual load of the seat valve...

    2009-01-01

    BACKGROUND: Pressure sores are localized injuries to the skin and underlying tissues and are mainly resulting from overpressure. Paraplegic peoples are particularly subjects to pressure sores because of long-time seated postures and sensory deprivation at the lower limbs. METHODOLOGY/PRINCIPAL FINDINGS: Here we report outcomes of a feasibility trial involving a biofeedback system aimed at reducing buttock overpressure whilst an individual is seated. The system consists of (1) pressure sensors, (2) a laptop coupling sensors and actuator (3) a wireless Tongue Display Unit (TDU) consisting of a circuit embedded in a dental retainer with electrodes put in contact with the tongue. The principle consists in (1) detecting overpressures in people who are seated over long periods of time, (2) estimating a postural change that could reduce these overpressures and (3) communicating this change through directional information transmitted by the TDU. Twenty-four healthy subjects voluntarily participated in this study. CON...

    2010-07-01

    We probe the effect of seating arrangement, group composition and group-based competition on students' performance in Physics using a teaching technique adopted from Mazur's peer instruction method. Ninety eight lectures, involving 2339 students, were conducted across nine learning institutions from February 2006 to June 2009. All the lectures were interspersed with student interaction opportunities (SIO), in which students work in groups to discuss and answer concept tests. Two individual assessments were administered before and after the SIO. The ratio of the post-assessment score to the pre-assessment score and the Hake factor were calculated to establish the improvement in student performance. Using actual assessment results and neural network (NN) modeling, an optimal seating arrangement for a class was determined based on student seating location. The NN model also provided a quantifiable method for sectioning students. Lastly, the study revealed that competition-driven interactions increase within-group cooperation and lead to higher improvement on the students' performance.

    Full Text Available Ergonomics (also called human factors engineering is the study of human characteristics for the appropriate design of the living and work environment. It is applied in various industrial areas which includes transportation.Tricycle being one of the most common means of public transportation in Lipa City has various adaptations to suit the culture, and environment. The purpose of this study is to analyze the variability in design of the tricycles in Lipa City, Philippines and propose a standard ergonomically designed tricycle sidecar seat for a greater population. The study was conducted at 26 tricycle terminals with 232 tricycle samples within Lipa City proper including the public market area where 400 commuters were given questionnaires to determine the risk factors associated with the existing tricycle sidecar seat design. Anthropometric measurements of 100 males and 100 female commuters were obtained together with the sidecar dimensions of 232 tricycles to substantiate the observed variations in design. Using the design for the average and design for the extremes, it was found out that most of the tricycles in Lipa City, Philippines have inappropriate inclined seat and lowered sidecar seat pan height which can result to leg and abdominal pain; narrowed seat pan depth which caused pressure on buttocks and legs; narrowed backrest width which can cause upper and low back pain; low backrest height that can pose upper back pain; which can also result to abdominal pain; inclined backrest and limited vertical clearance which can cause upper back pain and neck pain. The researcher proposed a sidecar seat design standard which can be used by the Land Transportation Office, and Land Transportation Franchising and Regulatory Board to provide ease, comfort, and convenience to the passengers.

    2016-06-01

    The aim of the smartphone virtual seating coach (SVSC) was to provide a personalized reminder/warning system to encourage powered wheelchair users to use their powered seating functions (PSFs) as clinically recommended. This study evaluated the usability of the SVSC system by gathering feedback from five powered wheelchair users and five rehabilitation professionals through questionnaires and interviews. The results indicated that clear and understandable instructions to adjust the PSFs are the most important requirement for SVSC application. The instructions must be intuitive, could benefit from animations or indications of PSFs control buttons so powered wheelchair users can adjust their PSFs immediately and appropriately.

    ZHAO Yun-cai; YAN Hang-zhi

    2005-01-01

    The wear failure course of gas-valve/valve-seat in engine was investigated with a simulating tester. The results show that the failure of the contact conical surface is mainly caused by the elastic and plastic deformation and the fatigue micro-crack and spalling. The creep-deformation and corrosion atmosphere accelerated wear failure course at the high temperature. The wear failure course of the gas-valve/valve-seat in engine follows general wear rules of mechanical elements, but the rate of wear in the sharp wear stage is faster.

  11. Who Owns Child Abuse?

    Directory of Open Access Journals (Sweden)

    Gerald Cradock

    2014-11-01

    Full Text Available Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement. In particular, the belief that child abuse determination is obvious. However, this assumption fails to make a distinction between nineteenth century’s emphasis on impoverished environments and the twentieth century introduction of the pathological child abuser. Moreover, the proliferation of kinds of child abuse, and the need to distinguish child abusers from non-abusers, means knowledge is now spread across an array of disciplines and professions, which necessarily destabilizes the definition of child abuse. The increasing exposure of alternate care systems as potentially abusive has similarly destabilized the old common sense solution to neglected children—namely removal. Finally, as uncertainty increases, and definitions become more divergent, the question of what child abuse is, and what should be done about it, becomes increasingly politicized.

    Even though Malaysia is a relatively prosperous country amongst the developing nations, it is still be set by problems of a rapidly increasing population. The economic cake is also unevenly distributed and there are pockets of poverty in the slums surrounding the towns as well as in the rural areas. Added to that is the problem of ignorance and superstition especially amongst its adult population. It is due to these problems that the Child-to-Child programme has found special application in Malaysia. The Child-to-Child has been introduced through either the government agencies or the voluntary organizations. Through the Ministry of Education, the concept has found its ways through the schools and the state department of education. The Ministry of Information and Broadcasting has also introduced the concept of Child-to-Child in the media. The voluntary organizations have also introduced the concept of Child-to-Child in their projects. The Sang Kancil project has to some extent used the idea in the running of its activities. The Health and Nutrition Education House have found that by applying the concept and using older children to help in running its activities, its over all objective which is the improvement of the health of the children in the slums could be reached more easily.

  14. What makes a child a 'competent' child?

    Science.gov (United States)

    van Rooyen, Amanda; Water, Tineke; Rasmussen, Shayne; Diesfeld, Kate

    2015-12-01

    Competence is a vital component of the informed consent process. The perceived level of a child's competence may influence their degree of participation in health decisions that affect them. It is the responsibility of the health professional to gauge a child's level of competence. Child competence, however, is not a static attribute that is linked to age. Rather, it is dynamic, changing in nature and dependent on a child's previous experiences, personal attributes, network of relationships around them and cultural and environmental context. Consequently, there is no single verified assessment tool to assist in the recognition of competence for New Zealand children. Adding to this complexity are the unclear interpretations of New Zealand health legislation and policy regarding whether or not a child can legally consent or refuse healthcare advice and treatment without the consent of a legal guardian. Under the Care of Children Act 2004 and the Code of Health and Disability Services Consumers' Rights 1996, the Health and Disability Commissioner states "a child may consent themselves [to health treatment] if and when the child achieves sufficient understanding and maturity to understand fully what is proposed". This paper poses the question: What is 'competency' and how is this decided? For the purpose of this article, 'child' pertains to those under the age of 16 years. PMID:26913912

    2016-08-01

    About 18 years ago, a large-scale discontinuous layer in properties and colour was found in the new Fengjie town at the shore of the Three Gorges Reservoir area in China. There are many resettled residents and buildings on the sloping area, the safety of which is potentially affected by this layer, so it has become the focus of attention. Before this study started there were two viewpoints regarding the origin of this layer. One was that is was from a huge ancient slide and the other was that is was from a fault graben. In order to find out how it was formed and to be able to carry out a stability analysis of the slope the authors have carried out a research program, including geological field investigations and mapping, a deep drilling hole, a geotechnical centrifuge model test, and a simulation analysis. The results of the research led to the conclusion that the layer is the sliding plane of a huge deep-seated ancient rock slide, which we called the Sanmashan landslide. An important argument for the conclusion is the recognition of a regional compressive tectonic stress field in this area, which cannot lead to the formation of a fault graben because it needs a tensional tectonic stress field. Moreover, numerous unique geological features, sliding marks, and other relics of the ancient slide have been discovered in the field. The formation process of the ancient slide could be repeated in a large geotechnical centrifuge model test. The test shows that a deformation and failure process of "creep-crack-cut" has occurred. The type of the ancient slide can be classified as a "successive rotational rock slide". Finally, the role of seepage in the stability of the Sanmashan landslide has been analysed. Our final conclusions are that, during rainfall and filling-drawdown cycles in the Three Gorges Reservoir, the Sanmashan landslide as a whole is dormant and stable and the secondary landslides in the toe area of the slope are presently stable but can be reactivated.

    2010-01-01

    Successful user discrimination in a vehicle environment may yield a reduction of the number of switches, thus significantly reducing costs while increasing user convenience. The personalization of individual controls permits conditional passenger enable/driver disable and vice versa options which may yield safety improvement. The authors propose a prototypic optical sensing system based on hand movement segmentation in near-infrared image sequences implemented in an Audi A6 Avant. Analyzing the number of movements in special regions, the system recognizes the direction of the forearm and hand motion and decides whether driver or front-seat passenger touch a control. The experimental evaluation is performed independently for uniformly and non-uniformly illuminated video data as well as for the complete video data set which includes both subsets. The general test results in error rates of up to 14.41% FPR / 16.82% FNR and 17.61% FPR / 14.77% FNR for driver and passenger respectively. Finally, the authors discuss the causes of the most frequently occurring errors as well as the prospects and limitations of optical sensing for user discrimination in passenger compartments.

While mechanical STS assistance can help address this problem, full dependence on STS assistance provided by devices such as lift chairs can lead to atrophy of the leg muscles. We investigated the mechanics of assisted STS motion in order to better understand how load-sharing STS mechanisms may facilitate STS motions while still requiring activation of the leg muscles. Experiments were conducted with 17 nondisabled older adults performing unassisted and assisted STS rises with grab bar, arm, seat, and waist assistance. Each mode of rise was evaluated based on a subject questionnaire and key biomechanical metrics relating to stability, knee effort reduction, and rise trajectory. Results show that the seat- and waist-assist modes provide statistically significant improvements in stability metrics and reductions in required knee torques over unassisted rises and bar assistance. The assists most preferred by the subjects were the seat and bar assists. Overall, our results favor a seat-assisted STS modality for nonclinical applications and indicate further testing of this modality with a clinical population.

  14. Active Vibration Isolation Using an Induced Strain Actuator with Application to Automotive Seat Suspensions

    Directory of Open Access Journals (Sweden)

    Mark Malowicki

    2001-01-01

    Full Text Available Active vibration isolation of automotive seats requires actuators that achieve millimeter-range displacements and forces on the order of 300 N. Recent developments in piezoceramic actuator technology provide a means for achieving these force and displacement levels in a compact device. This work demonstrates that prestressed, curved piezoceramic actuators achieve the force and displacement levels required for active isolation of automotive seats. An estimate of the force and displacement requirements are obtained from numerical simulations on a four-degree-of-freedom car and seat model that utilize representive road accelerations as inputs. An actuator that meets these specifications is designed using piezoceramic materials. Free displacement of 4.4 mm and blocked force greater than 300 N are measured. The actuator is integrated within a dead mass setup that simulates the isolation characteristics of an automotive seat. Control experiments demonstrate that active vibration is achievable with realistic road disturbances. Feedback control is able to eliminate any amplification due to mechanical resonance and reduce the isolation frequency from 9.5 Hz to 2 Hz.

    2016-09-01

    In firearm examiners' and forensic specialists' casework as well as in air gun proof testing, reliable measurement of the weapon's muzzle velocity is indispensable. While there are standardized and generally accepted procedures for testing the performance of air guns, the method of seating the diabolo pellets deeper into the breech of break barrel spring-piston air guns has not found its way into standardized test procedures. The influence of pellet seating on the external ballistic parameters was investigated using ten different break barrel spring-piston air guns. Test shots were performed with the diabolo pellets seated 2 mm deeper into the breech using a pellet seater. The results were then compared to reference shots with conventionally loaded diabolo pellets. Projectile velocity was measured with a high-precision redundant ballistic speed measurement system. In eight out of ten weapons, the muzzle energy increased significantly when the pellet seater was used. The average increase in kinetic energy was 31 % (range 9-96 %). To conclude, seating the pellet even slightly deeper into the breech of spring-piston air guns might significantly alter the muzzle energy. Therefore, it is strongly recommended that this effect is taken into account when accurate and reliable measurements of air gun muzzle velocity are necessary. PMID:27448569

  2. The Front Seat Passenger: How to Transfer Qualitative Findings into Design

    Directory of Open Access Journals (Sweden)

    Sebastian Osswald

    2013-01-01

    Full Text Available While the field of automotive HCI research abounds in driver-focused design and studies of driver distraction, relatively little attention has been directed to the front seat passengers. A challenge for designers and researchers is the ideation through exploration of passenger experiences and needs and the question of how to integrate them in design solutions. In this paper, we ground an ideation exercise based on results of a probing study conducted at two petrol stations. A probing package for front seat passengers was designed and distributed in cooperation with a petrol station company. Approximately 700 customers were approached randomly and 90 probe packages were handed out. 30 probing packages were returned and a segment clustering and a qualitative analysis were performed. The results gave insights into the activities and needs of front seat passengers and were then used in a design workshop together with a group of industrial designers. A set of ideas for novel interface solutions for front seat passengers were developed such as the invisible engine (look through the motor block with a display-based camera system. We further discuss the challenges and shortcomings of how to interpret and express ideas when transferring qualitative research findings into design.

    The preparation of rest seats must comply with specific sizes and shapes. Various technological systems such as Kavo PrepAssistant have been used as an auxiliary method to evaluate preclinical preparations more objectively. The aims of this study were to establish an alternative system for evaluating occlusal rest seats and to compare different types of assessment. Seventy-six undergraduate students at Oporto University Faculty of Dental Medicine in Portugal were selected as a convenience sample to prepare two occlusal rest seats in Kavo teeth #45 and #46 (FDI World Dental Federation ISO-3950) and were randomly assigned to two groups. Bearing in mind the ideal characteristics of rest seats, the investigators defined ten assessment parameters, and their evaluation weights were independently estimated by three evaluators. Four of these parameters were measured in Kavo PrepAssistant. The results of the different evaluation methods and evaluators varied considerably. The classical evaluation presented final results worse than those of the evaluations using parameters. In this study, carrying out the assessment with Kavo PrepAssistant helped to achieve a more objective and less evaluator-dependent final evaluation.

    2009-09-01

    Full Text Available This study compared outcomes of wheelchair seating and positioning interventions provided by telerehabilitation (n=10 and face-to-face (n=20; 10 in each of two comparison groups, one urban and one rural. Comparison clients were matched to the telerehabilitation clients in age, diagnosis, and type of seating components received. Clients and referring therapists rated their satisfaction and identified if seating intervention goals were met. Clients recorded travel expenses incurred or saved, and all therapists recorded time spent providing service. Wait times and completion times were tracked. Clients seen by telerehabilitation had similar satisfaction ratings and were as likely to have their goals met as clients seen face-to-face; telerehabilitation clients saved travel costs. Rural referring therapists who used telerehabilitation spent more time in preparation and follow-up than the other groups. Clients assessed by telerehabilitation had shorter wait times for assessment than rural face-to-face clients, but their interventions took as long to complete.

  10. Corrosion and Sliding Properties of the Nickel-Based Alloys for the Valve Seats Application

    International Nuclear Information System (INIS)

    This paper describes the experiments of the corrosion and the sliding tests of the nickel-based alloys for the gate valve seating materials used at high pressure and temperature. The general corrosion rates and IGC susceptibility are tested in pressurized water at 533 K and 575 k and in Strauss test solution. The sliding tests have been done in pressurized water at 293 k, 473 K and 573 k. The alloys containing above 10% chromium may have the anti-corrosion properties that could be applied to the valve seats for the power plants. The good sliding performance and the good pressure tightness are obtained when the disc specimens that have hardness 500 to 600 Hv combined with the seat specimens that have hardness 250 to 410 Hv containing about 40 percent of iron. The large size gate valves sliding tests have certified the test results. The anti-wear properties of the seat alloy and the anti-IGC susceptibility of the disc alloy could be improved by the addition of silicon and niobium, respectively

  11. Seat Capacity Selection for an Advanced Short-Haul Aircraft Design

    Marien, Ty V.

    2016-01-01

    A study was performed to determine the target seat capacity for a proposed advanced short-haul aircraft concept projected to enter the fleet by 2030. This analysis projected the potential demand in the U.S. for a short-haul aircraft using a transportation theory approach, rather than selecting a target seat capacity based on recent industry trends or current market demand. A transportation systems model was used to create a point-to-point network of short-haul trips and then predict the number of annual origin-destination trips on this network. Aircraft of varying seat capacities were used to meet the demand on this network, assuming a single aircraft type for the entire short-haul fleet. For each aircraft size, the ticket revenue and operational costs were used to calculate a total market profitability metric for all feasible flights. The different aircraft sizes were compared, based on this market profitability metric and also the total number of annual round trips and markets served. Sensitivity studies were also performed to determine the effect of changing the aircraft cruise speed and maximum trip length. Using this analysis, the advanced short-haul aircraft design team was able to select a target seat capacity for their design.

    2016-10-01

    This paper presents the development of an innovative seat suspension working with a rotary magnetorheological (MR) fluid damper. Compared with a conventional linear MR damper, the well-designed rotary MR damper possesses several advantages such as usage reduction of magnetorheological fluid, low sealing requirements and lower costs. This research starts with the introduction of the seat suspension structure and the damper design, followed by the property test of the seat suspension using an MTS machine. The field-dependent property, amplitude-dependent performance, and the frequency-dependent performance of the new seat suspension are measured and evaluated. This research puts emphasis on the evaluation of the vibration reduction capability of the rotary MR damper by using both simulation and experimental methods. Fuzzy logic is chosen to control the rotary MR damper in real time and two different input signals are considered as vibration excitations. The experimental results show that the rotary MR damper under fuzzy logic control is effective in reducing the vibrations.

    Background Seated workplaces have greatly increased in China.Many researchers have found that seated work is arisk factor in the development of low-back pain.Backrest can reduce the load on the lower back by transmitting more ofthe weight.from the upper body to the floor via the backrest so as to prevent low-back pain.To design a suitable chairbackrest for seated office work,some backrest parameters must be optimized.In this study,the role of backrest densityon lumbar load and comfort were investigated.The goal of the study was to help establish criteria with which backreststhat alleviate and prevent low back pain during seated office work can be designed and selected.Methods Twenty volunteers (10 men and 10 women) were seated in three backrest conditions (10 kg/m3,25 kg/m3,and 40 kg/m3).Pressure data,including contact pressure (CP),peak contact pressure (PCP) and contact area were collected during 15-minute trial.Subjective data were collected after each pressure test.Results Backrest density had a significant effect on backrest pressure variables.CP and PCP increased with increasing backrest density.Contact area decreased with increased density.In terms of user preference,the backrest with low density was most highly rated.Conclusions Backrest density plays an important role in lumbar load and comfort during seated work.During designing and selecting backrests,backrest density should be focused on so as to alleviate and prevent low-back pain during seated office work.Backrest density at 10 kg/m3 got the lowest CP and PCP and largest contact area.Backrest with low density can reduce lumbar pressure and increase support contact area,which could raise comfort feeling.Backrest density at 10 kg/m3 is better to maintain a balance between providing effective support and alleviating excess lordosis.Chin Med J 2012; 125(19):3505-3508

  18. From child to child: children as communicators.

    Science.gov (United States)

    Phinney, R; Evans, J

    1993-01-01

    Older children commonly care for their younger siblings while parents work to provide for the household. Through play, dance, and talk, children tend to interact with each other more intensely than do adults. In so doing, messages and awareness are exchanged more effectively. Child-to-Child is an active, child-centered learning approach which aims to capitalize on this phenomenon by training older siblings to be effective communicators. This approach has been formally practiced in over 70 countries since 1979. Child-to-Child encourages children to learn the meaning and importance of health messages on their own. Children will then be most likely to retain and communicate information throughout the family, to neighbors, and to the general community. No blueprint exists, however, on which program planners may base the design of new programs. Programs should instead be adapted by those living within the community and culture to fit local needs and circumstances. Nonetheless, the Aga Khan Foundation supported the study of 7 highly different Child-to-Child projects over 3 years in India to obtain some sense of which program elements are successful and potentially useful in other settings. The study revealed that all of the programs helped increase the health knowledge of children and teachers. Little information was obtained on the extent to which information was diffused by children within the community. Overall, the study produced the following results: planners should consider using Child-to-Child projects in schools; teacher training should be made a priority; administrative support should be provided; entire staffs should be made to feel involved in the decision making process; obstacles to changing teaching methods should not be underestimated; teaching materials should be locally made; projects should be integrated into official curricula; program topics should be relevant to local realities; respected authorities should be called upon to reinforce the validity

    2016-01-01

    BACKGROUND: Professional organizations recommend car seat testing of preterm infants before discharge from hospital. Late preterm infants (LPIs, 340/7 to 366/7 weeks’ gestational age) are at the greatest risk for failure, despite often being well. OBJECTIVE: To determine the incidence of car seat testing failure in LPIs and associative factors. METHODS: A retrospective chart review was performed of inborn LPIs admitted to all levels of newborn care between July 1, 2012 and June 30, 2013. Data collected included maternal demographics, labour and delivery history, and neonatal course. Data were analyzed using backward logistic regression. RESULTS: A total of 511 charts were reviewed and 367 LPIs were eligible for inclusion. Of the 313 LPIs tested (mean [± SD] gestational age 36 weeks ±6 days and birth weight 2614±405 g), 80 (26%) failed (95% CI 21% to 31%). Most failed due to desaturations (≥2) of <88% for ≥10 s (n=33 [41%]). Multiple gestation was associated with failure (adjusted OR 2.45 [95% CI 1.44 to 4.18]; P=0.001), and there was a trend toward statistical significance for the variable postnatal age (0.996 [95% CI 0.99 to 1.00]; P=0.05). Infants who passed their car seat test had higher postnatal ages than those who failed (mean difference 39.4 h [95% CI 12.7 h to 66.0 h]; P=0.004). CONCLUSION: Twenty-six percent of LPIs failed car seat testing. Ideally, infants should be tested after an appropriate transitional period. The authors identified factors that may be important in designing future, prospective studies in this area. Future research should evaluate the clinical significance of car seat testing and resource utilization. PMID:26941555
