  4. Aviation. (United States)

    Karl, Richard C


    An increased awareness of the need for safety in medicine in general and in surgery in particular has prompted comparisons between the cockpit and the operating room. These comparisons seem to make sense but tend to be oversimplified. Attempts in healthcare to mimic programs that have been credited for the safety of commercial aviation have met with varying results. The risk here is that oversimplified application of an aviation model may result in the abandonment of good ideas in medicine. This paper describes in more depth the differences between medicine and commercial aviation: from the hiring process, through initial operating experience, recurrent training, and the management of emergencies. These programs add up to a cultural difference. Aviation assumes that personnel are subject to mistake making and that systems and culture need to be constructed to catch and mitigate error; medicine is still focused on the perfection of each individual's performance. The implications of these differences are explored.

  8. Federal Aviation Administration retained savings program proposal

    Energy Technology Data Exchange (ETDEWEB)

    Hostick, D.J.; Larson, L.L. [Pacific Northwest National Lab., Richland, WA (United States); Hostick, C.J. [IBP, Inc., Pasco, WA (United States)


    Federal legislation allows federal agencies to retain up to 50% of the savings associated with implementing energy efficiency and water conservation measures and practices. Given budget pressures to reduce expenditures, the use of retained savings to fund additional projects represents a source of funds outside of the traditional budget cycle. The Southwest Region Federal Aviation Administration (FAA) has tasked Pacific Northwest National Laboratory (PNNL) to develop a model retained savings program for Southwest Region FAA use and as a prototype for consideration by the FAA. PNNL recommends the following steps be taken in developing a Southwest Region FAA retained savings program: Establish a retained savings mechanism. Determine the level at which the retained savings should be consolidated into a fund. The preliminary recommendation is to establish a revolving efficiency loan fund at the regional level. Such a mechanism allows some consolidation of savings to fund larger projects, while maintaining a sense of facility ownership in that the funds will remain within the region.

  12. Systems Analysis of NASA Aviation Safety Program: Final Report (United States)

    Jones, Sharon M.; Reveley, Mary S.; Withrow, Colleen A.; Evans, Joni K.; Barr, Lawrence; Leone, Karen


    A three-month study (February to April 2010) of the NASA Aviation Safety (AvSafe) program was conducted. This study comprised three components: (1) a statistical analysis of currently available civilian subsonic aircraft data from the National Transportation Safety Board (NTSB), the Federal Aviation Administration (FAA), and the Aviation Safety Information Analysis and Sharing (ASIAS) system to identify any significant or overlooked aviation safety issues; (2) a high-level qualitative identification of future safety risks, with an assessment of the potential impact of the NASA AvSafe research on the National Airspace System (NAS) based on these risks; and (3) a detailed, top-down analysis of the NASA AvSafe program using an established and peer-reviewed systems analysis methodology. The statistical analysis identified the top aviation "tall poles" based on NTSB accident and FAA incident data from 1997 to 2006. A separate examination of medical helicopter accidents in the United States was also conducted. Multiple external sources were used to develop a compilation of ten "tall poles" in future safety issues/risks. The top-down analysis of the AvSafe was conducted by using a modification of the Gibson methodology. Of the 17 challenging safety issues that were identified, 11 were directly addressed by the AvSafe program research portfolio.

  11. Effects of special composite stretching on the swing of amateur golf players. (United States)

    Lee, Joong-Chul; Lee, Sung-Wan; Yeo, Yun-Ghi; Park, Gi Duck


    [Purpose] The study investigated stretching for safer a golf swing compared to present stretching methods for proper swings in order to examine the effects of stretching exercises on golf swings. [Subjects] The subjects were 20 amateur golf club members who were divided into two groups: an experimental group which performed stretching, and a control group which did not. The subjects had no bone deformity, muscle weakness, muscle soreness, or neurological problems. [Methods] A swing analyzer and a ROM measuring instrument were used as the measuring tools. The swing analyzer was a GS400-golf hit ball analyzer (Korea) and the ROM measuring instrument was a goniometer (Korea). [Results] The experimental group showed a statistically significant improvement in driving distance. After the special stretching training for golf, a statistically significant difference in hit-ball direction deviation after swings were found between the groups. The experimental group showed statistically significant decreases in hit ball direction deviation. After the special stretching training for golf, statistically significant differences in hit-ball speed were found between the groups. The experimental group showed significant increases in hit-ball speed. [Conclusion] To examine the effects of a special stretching program for golf on golf swing-related factors, 20 male amateur golf club members performed a 12-week stretching training program. After the golf stretching training, statistically significant differences were found between the groups in hit-ball driving distance, direction deviation, deflection distance, and speed.

  12. PIFCGT: A PIF autopilot design program for general aviation aircraft (United States)

    Broussard, J. R.


    This report documents the PIFCGT computer program. In FORTRAN, PIFCGT is a computer design aid for determing Proportional-Integral-Filter (PIF) control laws for aircraft autopilots implemented with a Command Generator Tracker (CGT). The program uses Linear-Quadratic-Regulator synthesis algorithms to determine feedback gains, and includes software to solve the feedforward matrix equation which is useful in determining the command generator tracker feedforward gains. The program accepts aerodynamic stability derivatives and computes the corresponding aerodynamic linear model. The nine autopilot modes that can be designed include four maneuver modes (ROLL SEL, PITCH SEL, HDG SEL, ALT SEL), four final approach models (APR GS, APR LOCI, APR LOCR, APR LOCP), and a BETA HOLD mode. The program has been compiled and executed on a CDC computer.

  16. The science of golf

    CERN Document Server

    Wesson, John


    This book gives a scientific account of all aspects of the game of golf and answers the questions which occur to all who play the game. The mechanics of the swing and the impact of the club on the ball are explained. Together these decide the range of the ball - which is shown to be the most important factor for success. The aerodynamics of the ball's flight has several surprises, including the effects of dimples and spin. Understanding these effects allows a calculation of the ball's flight and explains how the range depends on the clubhead speed and the characteristics of the club. Putting is analyzed to find the optimum strategy and to understand how winds, slopes, and mud affect the run of the ball. Handicaps are perhaps the most discussed topic in golf and the book examines the handicaps system to identify their consequences in matches and competitions, with results which will surprise many players. The famous question - "what is the probability of a hole-in-one?" is discussed and a neat way of answering...

  18. CERTIFICATION - The final and critical stage of every civil or military aviation program

    Directory of Open Access Journals (Sweden)

    Vasile STEFAN


    Full Text Available As a general rule the final step in every aviation program is the certification of the airplane, an important step in which the airplane, the engins and the equipments are checked by an authority or commission according to the airworthiness rules. The main scope of the certification is to promote a safe aviation product and to protect the general public from unnecessary risk. In all the contries the national authorieties require a civil certificability for all the parts or equipments and a full aircraft certification for a new or wholly modified airplane. The military aircrafts must pased and respond to a specific way of certification and many actual efforts are done in order to unify the diffrent national rules in this field. This paper presents the existing situation in the certification of civil and military airplans and the actual measures done for the unification of certification procedures in the world.

  20. Evaluating Behaviorally Oriented Aviation Maintenance Resource Management (MRM) Training and Programs: Methods, Results, and Conclusions (United States)

    Taylor, James C.; Thomas, Robert L., III


    Assessment of the impact of Aviation Resource Management Programs on aviation culture and performance has compelled a considerable body of research (Taylor & Robertson, 1995; Taylor, 1998; Taylor & Patankar, 2001). In recent years new methods have been applied to the problem of maintenance error precipitated by factors such as the need for self-assessment of communication and trust. The present study - 2002 -- is an extension of that past work. This research project was designed as the conclusion of a larger effort to help understand, evaluate and validate the impact of Maintenance Resource Management (MRM) training programs, and other MRM interventions on participant attitudes, opinions, behaviors, and ultimately on enhanced safety performance. It includes research and development of evaluation methodology as well as examination of psychological constructs and correlates of maintainer performance. In particular, during 2002, three issues were addressed. First, the evaluation of two (independent & different) MRM programs for changing behaviors was undertaken. In one case we were able to further apply the approach to measuring written communication developed during 2001 (Taylor, 2002; Taylor & Thomas, 2003). Second, the MRM/TOQ surveys were made available for completion on the internet. The responses from these on-line surveys were automatically linked to a results calculator (like the one developed and described in Taylor, 2002) to aid industry users in analyzing and evaluating their local survey data on the internet. Third, the main trends and themes from our research about MRM programs over the past dozen years were reviewed.

  2. SPACE 365: Upgraded App for Aviation and Space-Related Information and Program Planning (United States)

    Williams, S.; Maples, J. E.; Castle, C. E.


    Foreknowledge of upcoming events and anniversary dates can be extraordinarily valuable in the planning and preparation of a variety of aviation and Space-related educational programming. Alignment of programming with items "newsworthy" enough to attract media attention on their own can result in effective program promotion at low/no cost. Similarly, awareness and avoidance of dates upon which media and public attention will likely be elsewhere can keep programs from being lost in the noise.NASA has created a useful and entertaining app called "SPACE 365" to help supply that foreknowledge. The app contains an extensive database of historical aviation and Space exploration-related events, along with other events and birthdays to provide socio-historical context, as well as an extensive file of present and future space missions, complete with images and videos. The user can search by entry topic category, date, and key words. Upcoming Events allows the user to plan, participate, and engage in significant "don't miss" happenings.The historical database was originally developed for use at the National Air and Space Museum, then expanded significantly to include more NASA-related information. The CIMA team at NASA MSFC, sponsored by the Planetary Science Division, added NASA current events and NASA educational programming information, and are continually adding new information and improving the functionality and features of the app. Features of SPACE 365 now include: NASA Image of the Day, Upcoming NASA Events, Event Save, Do Not Miss, and Ask Dr. Steve functions, and the CIMA team recently added a new start page and added improved search and navigation capabilities. App users can now socialize the Images of the Day via Twitter, Pinterest, Facebook, and other social media outlets.SPACE 365 is available at no cost from both the Apple appstore and GooglePlay, and has helped NASA, NASM, and other educators plan and schedule programming events. It could help you, too!

  11. A synoptic view of golf course management (United States)

    Katula, Robert L.


    The maintenance, construction, and redesign of private, public, and municipal golf courses in the United States is a multi-billion dollar industry. The entire golf course maintenance market, according to the National Golf Foundation, was 6.2 billion per year in 1991. The average maintenance cost in the United States was approximately 40,000 per hole per year for the over 15,000 golf courses in the United States in 1991. Golf course maintenance costs have risen 500 percent from 1971 to 1991. These costs are projected to continue to increase at a rate of 8 percent per year due to the demand for quality playing surfaces, increased use of non-potable water, and taxes on water and chemicals required to maintain turfgrass. The golf course construction and redesign market continues to maintain a rate of over 300 new golf courses and redesigned courses completed each year. The average construction costs run from 4 to 6 million and the average redesign costs 2 to 3 million per course. In order to create a perfectly maintained golf course, golf course managers may use as many as 25 different pesticides, fertilizers, and herbicides to control insects and turf disease. Further, turfgrass is often stressed to its limits when kept at the unnatural heights required to obtain firm and fast greens and fairways. The daily practice of living on the edge is often done with limited knowledge of changes taking place on the golf course, of the location of soil types and fertility, of surface and subsurface drainage, and of previous maintenance practices. There is a growing concern in the golf course industry that the concentration of chemicals and water required to maintain today's golf course may endanger ground water supplies for the surrounding ecosystem. This paper will describe the general methodology PTS used to develop a new management system for the maintenance, construction, and redesign of golf courses. The management system integrates remote sensing technology, geographic

  13. Highlight summarization in golf videos using audio signals (United States)

    Kim, Hyoung-Gook; Kim, Jin Young


    In this paper, we present an automatic summarization of highlights in golf videos based on audio information alone without video information. The proposed highlight summarization system is carried out based on semantic audio segmentation and detection on action units from audio signals. Studio speech, field speech, music, and applause are segmented by means of sound classification. Swing is detected by the methods of impulse onset detection. Sounds like swing and applause form a complete action unit, while studio speech and music parts are used to anchor the program structure. With the advantage of highly precise detection of applause, highlights are extracted effectively. Our experimental results obtain high classification precision on 18 golf games. It proves that the proposed system is very effective and computationally efficient to apply the technology to embedded consumer electronic devices.

  15. Integration of structural health monitoring solutions onto commercial aircraft via the Federal Aviation Administration structural health monitoring research program (United States)

    Swindell, Paul; Doyle, Jon; Roach, Dennis


    The Federal Aviation Administration (FAA) started a research program in structural health monitoring (SHM) in 2011. The program's goal was to understand the technical gaps of implementing SHM on commercial aircraft and the potential effects on FAA regulations and guidance. The program evolved into a demonstration program consisting of a team from Sandia National Labs Airworthiness Assurance NDI Center (AANC), the Boeing Corporation, Delta Air Lines, Structural Monitoring Systems (SMS), Anodyne Electronics Manufacturing Corp (AEM) and the FAA. This paper will discuss the program from the selection of the inspection problem, the SHM system (Comparative Vacuum Monitoring-CVM) that was selected as the inspection solution and the testing completed to provide sufficient data to gain the first approved use of an SHM system for routine maintenance on commercial US aircraft.

  19. Golf hand prosthesis performance of transradial amputees. (United States)

    Carey, Stephanie L; Wernke, Matthew M; Lura, Derek J; Kahle, Jason T; Dubey, Rajiv V; Highsmith, M Jason


    Typical upper limb prostheses may limit sports participation; therefore, specialized terminal devices are often needed. The purpose of this study was to evaluate the ability of transradial amputees to play golf using a specialized terminal device. Club head speed, X-factor, and elbow motion of two individuals with transradial amputations using an Eagle Golf terminal device were compared to a non-amputee during a golf swing. Measurements were collected pre/post training with various stances and grips. Both prosthesis users preferred a right-handed stance initially; however, after training, one preferred a left-handed stance. The amputees had slower club head speeds and a lower X-factor compared to the non-amputee golfer, but increased their individual elbow motion on the prosthetic side after training. Amputees enjoyed using the device, and it may provide kinematic benefits indicated by the increase in elbow flexion on the prosthetic side. The transradial amputees were able to swing a golf club with sufficient repetition, form, and velocity to play golf recreationally. Increased elbow flexion on the prosthetic side suggests a potential benefit from using the Eagle Golf terminal device. Participating in recreational sports can increase amputees' health and quality of life. © The International Society for Prosthetics and Orthotics 2014.

    Full Text Available Golf is an extremely complex game which depends on a number of interconnected factors. One of the most important elements is undoubtedly the golf swing technique. High performance of the golf swing technique is generated by: the level of motor abilities, high degree of movement control, the level of movement structure stabilisation, morphological characteristics, inter- and intro-muscular coordination, motivation, and concentration. The golf swing technique was investigated using the biomechanical analysis method. Kinematic parameters were registered using two synchronised high-speed cameras at a frequency of 2,000 Hz. The sample of subjects consisted of three professional golf players. The study results showed a relatively high variability of the swing technique. The maximum velocity of the ball after a wood swing ranged from 233 to 227 km/h. The velocity of the ball after an iron swing was lower by 10 km/h on average. The elevation angle of the ball ranged from 11.7 to 15.3 degrees. In the final phase of the golf swing, i.e. downswing, the trunk rotators play the key role.

  1. Corporate Social Responsibility in Aviation (United States)

    Phillips, Edwin D.


    The dialog within aviation management education regarding ethics is incomplete without a discussion of corporate social responsibility (CSR). CSR research requires discussion involving: (a) the current emphasis on CSR in business in general and aviation specifically; (b) business and educational theory that provide a basis for aviation companies to engage in socially responsible actions; (c) techniques used by aviation and aerospace companies to fulfill this responsibility; and (d) a glimpse of teaching approaches used in university aviation management classes. The summary of this research suggests educators explain CSR theory and practice to students in industry and collegiate aviation management programs. Doing so extends the discussion of ethical behavior and matches the current high level of interest and activity within the aviation industry toward CSR.

  2. Injuries and overuse syndromes in golf. (United States)

    Gosheger, Georg; Liem, Dennis; Ludwig, Karl; Greshake, Oliver; Winkelmann, Winfried


    Although golf is becoming more popular, there is a lack of reliable epidemiologic data on golf injuries and overuse syndromes, especially regarding their severity. To perform an epidemiologic study of the variety of different musculoskeletal problems in professional and amateur golfers and to find associations of age, sex, physical stature (body mass index), warm-up routine, and playing level with the occurrence of reported injuries. Retrospective cohort study. We analyzed the injury data from a total of 703 golfers who were randomly selected over two golfing seasons and interviewed with the use of a six-page questionnaire. Overall, 82.6% (N = 526) of reported injuries involved overuse and 17.4% (N = 111) were single trauma events. Professional golfers were injured more often, typically in the back, wrist, and shoulder. Amateurs reported many elbow, back, and shoulder injuries. Severity of reported injuries was minor in 51.5%, moderate in 26.8%, and major in 21.7% of cases. Carrying one's bag proved to be hazardous to the lower back, shoulder, and ankle. Warm-up routines were found to have a positive effect if they were at least 10 minutes long. Overall, golf may be considered a rather benign activity, if overuse can be avoided. If not, golf can result in serious, chronic musculoskeletal problems.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Georgia Army National Guard property located on Hunter Army Airfield (HAA) near Savannah, Georgia, known as Army Aviation Support Facility (AASF) No. 3. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, types and quantities of hazardous substances utilized, the nature and amounts of wastes generated or stored at the facility, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the AASF No. 3 property, requirements of the Department of Defense Installation Restoration Program (IRP). The scope of this assessment is limited to the facilities and past activities contained within the area now occupied by AASF No. 3. However, this assessment report is intended to be read in conjunction with a previous IRP assessment of HAA completed in 1992 (USATHAMA 1992) and to provide comprehensive information on AASF No. 3 for incorporation with information contained in that previous assessment for the entirety of HAA.

  15. Satellite Delivery of Aviation Weather Data (United States)

    Kerczewski, Robert J.; Haendel, Richard


    With aviation traffic continuing to increase worldwide, reducing the aviation accident rate and aviation schedule delays is of critical importance. In the United States, the National Aeronautics and Space Administration (NASA) has established the Aviation Safety Program and the Aviation System Capacity Program to develop and test new technologies to increase aviation safety and system capacity. Weather is a significant contributor to aviation accidents and schedule delays. The timely dissemination of weather information to decision makers in the aviation system, particularly to pilots, is essential in reducing system delays and weather related aviation accidents. The NASA Glenn Research Center is investigating improved methods of weather information dissemination through satellite broadcasting directly to aircraft. This paper describes an on-going cooperative research program with NASA, Rockwell Collins, WorldSpace, Jeppesen and American Airlines to evaluate the use of satellite digital audio radio service (SDARS) for low cost broadcast of aviation weather information, called Satellite Weather Information Service (SWIS). The description and results of the completed SWIS Phase 1 are presented, and the description of the on-going SWIS Phase 2 is given.

  18. Developing and Utilizing Ontology of Golf Based on the Open Travel Alliance Golf Messages (United States)

    Cieślik, Agnieszka; Ganzha, Maria; Paprzycki, Marcin

    While the vision of the Semantic Web is an extremely appealing one, its success depends not only on development of new ontologies that represent various aspects of the world. Pragmatic view suggests that such activities have to go hand-in-hand with facilitating support for existing domain-specific real-world standards. One of such interesting standards that is systematically gaining popularity in the travel industry, is the Open Travel Alliance (OTA) messaging. Specifically, the OTA standardizes the way that businesses in the travel industry can communicate with each other. The aim of this chapter is to outline our efforts leading toward (re)engineering an ontology of golf (understood as a leisurely activity) anchored in the OTA golf messaging specification. Furthermore we discuss how such ontology could be used in a Travel Support System. Here, in addition to general scenarios, details concerning implementation of needed translators are presented.

    Fedorcik, Gregory G; Queen, Robin M; Abbey, Alicia N; Moorman, Claude T; Ruch, David S


    Variation in swing mechanics between golfers of different skill levels has been previously reported. To investigate if differences in three-dimensional wrist kinematics and the angle of golf club descent between low and high handicap golfers. A descriptive laboratory study was performed with twenty-eight male golfers divided into two groups, low handicap golfers (handicap = 0-5, n = 15) and high handicap golfers (handicap ≥ 10, n = 13). Bilateral peak three-dimensional wrist mechanics, bilateral wrist mechanics at ball contact (BC), peak angle of descent from the end of the backswing to ball contact, and the angle of descent when the forearm was parallel to the ground (DEC-PAR) were determined using an 8 camera motion capture system. Independent t-tests were completed for each study variable (α = 0.05). Pearson correlation coefficients were determined between golf handicap and each of the study variables. The peak lead arm radial deviation (5.7 degrees, p = 0.008), lead arm radial deviation at ball contact (7.1 degrees, p = 0.001), and DEC-PAR (15.8 degrees, p = 0.002) were significantly greater in the high handicap group. In comparison with golfers with a low handicap, golfers with a high handicap have increased radial deviation during the golf swing and at ball contact. Copyright © 2011 Sports Medicine Australia.

    Jung, Hyesun; Lee, Jong-Eun; Kim, Jiyun


    The aim of this study was to identify job stress level and to elucidate the factors associated with job stress among female golf caddies as a specific job group in South Korea. The sample included 228 female caddies from 9 golf resorts in this descriptive cross-sectional study. Descriptive analysis and hierarchical regression were conducted to examine significant correlations between variables. The hierarchical regression model for job stress explained 26.8% of the variance among those with a low monthly income (β =-0.151, p=0.021), an irregular diet (β=0.165, p=0.014), and high daily work hours (β=0.380, p=0.000), showing that these respondents were more likely to report high job stress levels. The findings of this study underscore the urgent need to improve job stress levels and factors related to job stress among female golf caddies. Future intervention programs for this job of specific case should focus on improving job stress and coping strategies.

  4. Ejection of a rear facing, golf cart passenger. (United States)

    Schau, Kyle; Masory, Oren


    The following report details the findings of a series of experiments and simulations performed on a commercially available, shuttle style golf cart during several maneuvers involving rapid accelerations of the vehicle. It is determined that the current set of passive restraints on these types of golf carts are not adequate in preventing ejection of a rear facing passenger during rapid accelerations in the forward and lateral directions. Experimental data and simulations show that a hip restraint must be a minimum of 13 in. above the seat in order to secure a rear facing passenger during sharp turns, compared to the current restraint height of 5 in. Furthermore, it is determined that a restraint directly in front of the rear facing passenger is necessary to prevent ejection. In addressing these issues, golf cart manufacturers could greatly reduce the likelihood of injury due to ejection of a rear facing, golf cart passenger. Copyright © 2013 Elsevier Ltd.

    Full Text Available This study assessed human kinetics in relation to golf shoe outer sole design features during the golf swing using a driver club by measuring both within the shoe, and beneath the shoe at the natural grass interface. Three different shoes were assessed: metal 7- spike shoe, alternative 7-spike shoe, and a flat soled shoe. In-shoe plantar pressure data were recorded using Footscan RS International pressure insoles and sampling at 500 Hz. Simultaneously ground reaction force at the shoe outer sole was measured using 2 natural grass covered Kistler force platforms and 1000 Hz data acquisition. Video recording of the 18 right-handed golfers at 200 Hz was undertaken while the golfer performed 5 golf shots with his own driver in each type of shoe. Front foot (nearest to shot direction maximum vertical force and torque were greater than at the back foot, and there was no significant difference related to the shoe type. Wearing the metal spike shoe when using a driver was associated with more torque generation at the back foot (p < 0. 05 than when the flat soled shoe was worn. Within shoe regional pressures differed significantly with golf shoe outer sole design features (p < 0.05. Comparison of the metal spike and alternative spike shoe results provided indications of the quality of regional traction on the outer sole. Potential golf shoe outer sole design features and traction were presented in relation to phases of the golf swing movement. Application of two kinetic measurement methods identified that moderated (adapted muscular control of foot and body movement may be induced by golf shoe outer sole design features. Ground reaction force measures inform comparisons of overall shoe functional performance, and insole pressure measurements inform comparisons of the underfoot conditions induced by specific regions of the golf shoe outer sole

    Full Text Available Golf has been recommended as a relatively risk-free form of exercise for an ageing population. The aim of this study was to investigate the effects of playing a round of golf on mood states in recreational players. Ageing male golfers (N = 34; Age: M = 68.7, SD = 5.4 years completed a mood measure immediately before and after an 18-hole round of golf. Distance walked per game was measured using a pedometer. Results indicate reported scores on Anger, Depression, and Fatigue increased and Vigor reduced following the game. However, it should be noted that although there was an increase in unpleasant mood states, this should be seen in the context of the overall mood profile, which was positive. Pedometer results indicated golfers walked a mean distance of 10.21 km (± 1.11. Results show participants of this age-group engaged in a meaningful exercise session and that mood scores deteriorated following play. Findings from the present study show that elderly golfers experienced mood profiles following golf similar to younger athletes following competition. For golf to be recommended as an activity for promoting physical activity among an aging population, the player's ability to regulate unpleasant mood states should be considered. Future research should investigate the effects of experiencing negative mood states following golf on motivation to participate.

    The particular challenges of our time require a consistent focus on the development activities of powertrain technologies with continuously reduced fuel consumption and CO2 emissions. The past years have seen many technological milestones by Volkswagen's Powertrain Development as illustrated by the exceptional success of the TSI and TDI engines as well as the double clutch transmissions. As a part of this comprehensive list of powertrain strategy, the development of drivetrains for alternative fuels, such as CNG, has also been included. With particular emphasis Volkswagen is pressing forward the electrification of the drivetrain with the goal of appealing to more customers through these new technologies. A milestone of the electrification activity is the Golf Blue-e-Motion, in which the comfort and especially the city driving performance are improved compared with the conventional vehicle. This driving performance is achieved by an electric drivetrain which consists of a permanent magnet synchronous electric motor together with associated power electronics and a Li-Ion battery. This presentation will pay particular attention to the characteristics of the drivetrain system and its components. The efficient powertrain including the recovering of braking energy (recuperation) as well as the attention paid on optimising all system components, has increased the driving range of the vehicle. Environmental awareness and driving pleasure - the electric drivetrain of the Golf Blue-e-Motion shows that these both requirements are possible to be realised by an electric drivetrain. (orig.)

  10. Reuse of reclaimed wastewater for golf course irrigation in Tunisia. (United States)

    Bahri, A; Basset, C; Oueslati, F; Brissaud, F


    In Tunisia, golf courses are irrigated with secondary treated effluent stored in landscape impoundments. The impact of the conveyance and storage steps on the physical-chemical and biological quality of irrigation water was evaluated on three golf courses over two years. It was found that the water quality varies all along the water route, from the wastewater treatment plant up to the irrigation site: nutrient and bacteria contents decreased along the route in the three cases. This variation depends on the wastewater quality, the length of the pipes conveying water, the number of regulation reservoirs and ponds, the water residence time in pipes, reservoirs and ponds, and the operation of the ponds. The bacteriological quality of irrigation water deteriorates during the irrigation period in the three golf courses as the ponds are operated as continuous flow reactors. The results obtained in this study indicate the inability of golf water supplies, as currently managed, to properly sanitize reclaimed wastewater and meet target quality criteria recommended by WHO (1989) for water intended for recreational use. For a safe reuse of reclaimed wastewater for golf course irrigation, changes in the design and operation of the ponds should be planned or additional treatment steps provided.

    Full Text Available A work and power (energy analysis of the golf swing is presented as a method for evaluating the mechanics of the golf swing. Two computer models were used to estimate the energy production, transfers, and conversions within the body and the golf club by employing standard methods of mechanics to calculate work of forces and torques, kinetic energies, strain energies, and power during the golf swing. A detailed model of the golf club determined the energy transfers and conversions within the club during the downswing. A full-body computer model of the golfer determined the internal work produced at the body joints during the downswing. Four diverse amateur subjects were analyzed and compared using these two models. The energy approach yielded new information on swing mechanics, determined the force and torque components that accelerated the club, illustrated which segments of the body produced work, determined the timing of internal work generation, measured swing efficiencies, calculated shaft energy storage and release, and proved that forces and range of motion were equally important in developing club head velocity. A more comprehensive description of the downswing emerged from information derived from an energy based analysis

  12. Burrowing owl nesting productivity: A comparison between artificial and natural burrows on and off golf courses (United States)

    Smith, M.D.; Conway, C.J.; Ellis, L.A.


    Burrowing owl (Athene cunicularia) populations are declining in many portions of their range, and lack of suitable nesting burrows is thought to be one reason for observed declines. Burrowing owls are attracted to golf courses because the birds generally nest and forage in short-grass, open areas, yet golf courses seldom have suitable nesting burrows. We examined the efficacy of installing artificial nesting burrows on golf courses as a way to help restore local burrowing owl populations. From 2001-2004 we monitored over 175 natural burrows off golf courses, 14 natural burrows on golf courses, 86 artificial burrows off golf courses, and 130 artificial burrows on golf courses. Owls located and used 8 of the 130 artificial burrows installed on golf courses (4 were used as nests). Owls selected burrows that were closer to existing natural burrows, farther from maintained areas (areas receiving turf maintenance by golf course staff), and farther from sprinkler heads. All 4 of the artificial burrows used as nests successfully fledged young, and annual site fidelity for owls nesting on golf courses was higher than for owls nesting off golf courses. However, annual fecundity of owls nesting on golf courses was lower than that of owls nesting off golf courses. If golf courses have sufficiently large nonmaintained areas and there are nesting owls nearby, course managers potentially can help in restoring local burrowing owl populations by installing artificial nesting burrows on the periphery of the course. However, the low fecundity on golf courses reported here should be more thoroughly examined before artificial burrows are used to attract owls to golf courses.

  13. Development and use of computational techniques in Army Aviation research and development programs for crash resistant helicopter technology (United States)

    Burrows, Leroy T.


    During the 1960's over 30 full-scale aircraft crash tests were conducted by the Flight Safety Foundation under contract to the Aviation Applied Technology Directorate (AATD) of the U.S. Army Aviation Systems Command (AVSCOM). The purpose of these tests were to conduct crash injury investigations that would provide a basis for the formulation of sound crash resistance design criteria for light fixed-wing and rotary wing aircraft. This resulted in the Crash Survival Design Criteria Designer's Guide which was first published in 1967 and has been revised numerous times, the last being in 1989. Full-scale aircraft crash testing is an expensive way to investigate structural deformations of occupied spaces and to determine the decelerative loadings experienced by occupants in a crash. This gave initial impetus to the U.S. Army to develop analytical methods to predict the dynamic response of aircraft structures in a crash. It was believed that such analytical tools could be very useful in the preliminary design stage of a new helicopter system which is required to demonstrate a level of crash resistance and had to be more cost effective than full-scale crash tests or numerous component design support tests. From an economic point of view, it is more efficient to optimize for the incorporation of crash resistance features early in the design stage. However, during preliminary design it is doubtful if sufficient design details, which influence the exact plastic deformation shape of structural elements, will be available. The availability of simple procedures to predict energy absorption and load-deformation characteristics will allow the designer to initiate valuable cost, weight, and geometry tradeoff studies. The development of these procedures will require some testing of typical specimens. This testing should, as a minimum, verify the validity of proposed procedures for providing pertinent nonlinear load-deformation data. It was hoped that through the use of these

  16. Ocular Dominance and Handedness in Golf Putting. (United States)

    Dalton, Kristine; Guillon, Michel; Naroo, Shehzad A


    In golf, the impact of eye-hand dominance on putting performance has long been debated. Eye-hand dominance is thought to impact how golfers judge the alignment of the ball with the target and the club with the ball, as well as how golfers visualize the line of the putt when making decisions about the force needed to hit the ball. Previous studies have all measured ocular dominance in primary gaze only, despite golfers spending a significant amount of their time in a putting stance (bent at the hips, head tilted down). Thus, the purpose of this study was to assess ocular dominance in both primary gaze (aligning the ball with the target) and putting gaze (addressing the ball and aligning the club). This study investigated measuring pointing ocular dominance in both primary and putting gaze positions on 31 golfers (14 amateur, 7 club professionals, and 10 top professionals). All players were right-handed golfers, although one reported having no hand dominance and one reported being strongly left hand dominant. The results showed that (1) primary and putting gaze ocular dominances are not equal, nor are they predictive of each other; (2) the magnitude of putting ocular dominance is significantly less than the magnitude of primary gaze ocular dominance; (3) ocular dominance is not correlated with handedness in either primary or putting gaze; and (4) eye-hand dominance is not associated with increased putting skill, although ocular dominance may be associated with increased putting success. It is important that coaches assess golfers' ocular dominance in both primary and putting gaze positions to ensure they have the most accurate information upon which to base their vision strategy decisions.

Golf course is a unique ecosystem where plant parasitic nematodes inhabit and become  important pest because they reduce the quality of the grass.  The pest problems on golf course can be indicated by its characteristics of nematode community.  Survey on nematodes community at PGS Golf Course Bandar Lampung was conducted from March to December 2004.  The objective was to study the characteristics of nematode community in the part of golf courses hole (green, collar, apron, and fairway.  Soil samples were taken from five holes each of it consists of green, collar, apron, and fairway, respectiveley.  Nematodes extraction was done in Laboratory of Arthropod Pest, Department of Plant Protection University of Lampung.   The result showed that at least 50 nematodes genera of 28 families inhabit PGS. The number of plant parasitic nematode genera was higher than the free-living one.  The characteristic of nematodes community on green and collar was different than on faiway. Nematode abundance and diversity on green and collar were higher than on fairway.  Based on abundance of nematode feeding group, maturity index of free-living nematodes (MI and that of plant parasitic nematodes (PPI, green and collar part seemed to be more favorable to plant parasitic nematodes than free-living nematodes. The contrary happened for fairway.  Four most dominant genera of plant parasitic nematodes on PGS golf course were Helicotylenchus, Hoplolaimus, Criconemella, and Xiphinema.

  20. Effects of Terrestrial Buffer Zones on Amphibians on Golf Courses (United States)

    Puglis, Holly J.; Boone, Michelle D.


    A major cause of amphibian declines worldwide is habitat destruction or alteration. Public green spaces, such as golf courses and parks, could serve as safe havens to curb the effects of habitat loss if managed in ways to bolster local amphibian communities. We reared larval Blanchard's cricket frogs (Acris blanchardi) and green frogs (Rana clamitans) in golf course ponds with and without 1 m terrestrial buffer zones, and released marked cricket frog metamorphs at the golf course ponds they were reared in. Larval survival of both species was affected by the presence of a buffer zone, with increased survival for cricket frogs and decreased survival for green frogs when reared in ponds with buffer zones. No marked cricket frog juveniles were recovered at any golf course pond in the following year, suggesting that most animals died or migrated. In a separate study, we released cricket frogs in a terrestrial pen and allowed them to choose between mown and unmown grass. Cricket frogs had a greater probability of using unmown versus mown grass. Our results suggest that incorporating buffer zones around ponds can offer suitable habitat for some amphibian species and can improve the quality of the aquatic environment for some sensitive local amphibians.

  1. The variable and chaotic nature of professional golf performance. (United States)

    Stöckl, Michael; Lamb, Peter F


    In golf, unlike most other sports, individual performance is not the result of direct interactions between players. Instead decision-making and performance is influenced by numerous constraining factors affecting each shot. This study looked at the performance of PGA TOUR golfers in 2011 in terms of stability and variability on a shot-by-shot basis. Stability and variability were assessed using Recurrence Quantification Analysis (RQA) and standard deviation, respectively. About 10% of all shots comprised short stable phases of performance (3.7 ± 1.1 shots per stable phase). Stable phases tended to consist of shots of typical performance, rather than poor or exceptional shots; this finding was consistent for all shot categories. Overall, stability measures were not correlated with tournament performance. Variability across all shots was not related to tournament performance; however, variability in tee shots and short approach shots was higher than for other shot categories. Furthermore, tee shot variability was related to tournament standing: decreased variability was associated with better tournament ranking. The findings in this study showed that PGA TOUR golf performance is chaotic. Further research on amateur golf performance is required to determine whether the structure of amateur golf performance is universal.

  4. Risk Factors for Knee Injury in Golf: A Systematic Review. (United States)

    Baker, Matthew L; Epari, Devakar R; Lorenzetti, Silvio; Sayers, Mark; Boutellier, Urs; Taylor, William R


    Golf is commonly considered a low-impact sport that carries little risk of injury to the knee and is generally allowed following total knee arthroplasty (TKA). Kinematic and kinetic studies of the golf swing have reported results relevant to the knee, but consensus as to the loads experienced during a swing and how the biomechanics of an individual's technique may expose the knee to risk of injury is lacking. Our objective was to establish (1) the prevalence of knee injury resulting from participation in golf and (2) the risk factors for knee injury from a biomechanical perspective, based on an improved understanding of the internal loading conditions and kinematics that occur in the knee from the time of addressing the ball to the end of the follow-through. A systematic literature search was conducted to determine the injury rate, kinematic patterns, loading, and muscle activity of the knee during golf. A knee injury prevalence of 3-18% was established among both professional and amateur players, with no clear dependence on skill level or sex; however, older players appear at greater risk of injury. Studies reporting kinematics indicate that the lead knee is exposed to a complex series of motions involving rapid extension and large magnitudes of tibial internal rotation, conditions that may pose risks to the structures of a natural knee or TKA. To date, the loads experienced by the lead knee during a golf swing have been reported inconsistently in the literature. Compressive loads ranging from 100 to 440% bodyweight have been calculated and measured using methods including inverse dynamics analysis and instrumented knee implants. Additionally, the magnitude of loading appears to be independent of the club used. This review is the first to highlight the lack of consensus regarding knee loading during the golf swing and the associated risks of injury. Results from the literature suggest the lead knee is subject to a higher magnitude of stress and more demanding

  6. Aviation Safety Reporting System: Process and Procedures (United States)

    Connell, Linda J.


    The Aviation Safety Reporting System (ASRS) was established in 1976 under an agreement between the Federal Aviation Administration (FAA) and the National Aeronautics and Space Administration (NASA). This cooperative safety program invites pilots, air traffic controllers, flight attendants, maintenance personnel, and others to voluntarily report to NASA any aviation incident or safety hazard. The FAA provides most of the program funding. NASA administers the program, sets its policies in consultation with the FAA and aviation community, and receives the reports submitted to the program. The FAA offers those who use the ASRS program two important reporting guarantees: confidentiality and limited immunity. Reports sent to ASRS are held in strict confidence. More than 350,000 reports have been submitted since the program's beginning without a single reporter's identity being revealed. ASRS removes all personal names and other potentially identifying information before entering reports into its database. This system is a very successful, proof-of-concept for gathering safety data in order to provide timely information about safety issues. The ASRS information is crucial to aviation safety efforts both nationally and internationally. It can be utilized as the first step in safety by providing the direction and content to informed policies, procedures, and research, especially human factors. The ASRS process and procedures will be presented as one model of safety reporting feedback systems.

    Shimchik Ilya


    Full Text Available This paper presents our approach to development of an autonomous golf cart, which will navigate in inaccessible by regular vehicles private areas. For this purpose, we have built a virtual golf course terrain and golf cart model in Gazebo, selected and modernized ROS-based packages in order to use them with Ackermann steering vehicle simulation. To verify our simulation and algorithms, we navigated the golf cart model from one golf hole to another within a virtual 3D golf course. For the real world algorithms’ verification, we developed a small-size vehicle prototype based on Traxxas radio-controlled car model, which is equipped with an on-board controller and sensors. The autonomous navigation of Traxxas-based vehicle prototype has been tested in indoor environment, where it utilized sensory data about environment and vehicle states, and performed localization, optimal trajectory computation and dynamic obstacles’ recognition with adjusting the route in real time.

  11. Simulation and Test of a Fuel Cell Hybrid Golf Cart

    Jingming Liang


    Full Text Available This paper establishes the simulation model of fuel cell hybrid golf cart (FCHGC, which applies the non-GUI mode of the Advanced Vehicle Simulator (ADVISOR and the genetic algorithm (GA to optimize it. Simulation of the objective function is composed of fuel consumption and vehicle dynamic performance; the variables are the fuel cell stack power sizes and the battery numbers. By means of simulation, the optimal parameters of vehicle power unit, fuel cell stack, and battery pack are worked out. On this basis, GUI mode of ADVISOR is used to select the rated power of vehicle motor. In line with simulation parameters, an electrical golf cart is refitted by adding a 2 kW hydrogen air proton exchange membrane fuel cell (PEMFC stack system and test the FCHGC. The result shows that the simulation data is effective but it needs improving compared with that of the real cart test.

    Full Text Available Swinging a golf club includes the rotation and extension of the lumbar spine. Golf-related low back pain has been associated with degeneration of the lumbar facet and intervertebral discs, and with spondylolysis. Reflective markers were placed directly onto the skin of 11young male amateur golfers without a previous history of back pain. Using a VICON system (Oxford Metrics, U.K., full golf swings were monitored without a corset (WOC, with a soft corset (SC, and with a hard corset (HC, with each subject taking 3 swings. Changes in the angle between the pelvis and the thorax (maximum range of motion and angular velocity in 3 dimensions (lumbar rotation, flexion-extension, and lateral tilt were analyzed, as was rotation of the hip joint. Peak changes in lumbar extension and rotation occurred just after impact with the ball. The extension angle of the lumbar spine at finish was significantly lower under SC (38° or HC (28° than under WOC (44° conditions (p < 0.05. The maximum angular velocity after impact was significantly smaller under HC (94°/sec than under SC (177°/sec and WOC (191° /sec conditions, as were the lumbar rotation angles at top and finish. In contrast, right hip rotation angles at top showed a compensatory increase under HC conditions. Wearing a lumbar corset while swinging a golf club can effectively decrease lumbar extension and rotation angles from impact until the end of the swing. These effects were significantly enhanced while wearing an HC

  14. Golf and upper limb injuries: a summary and review of the literature

    Pollard Henry P


    Full Text Available Abstract Background Golf is a popular past time that provides exercise with social interaction. However, as with all sports and activities, injury may occur. Many golf-related injuries occur in the upper limb, yet little research on the potential mechanisms of these injuries has been conducted. Objective To review the current literature on golf-related upper limb injuries and report on potential causes of injury as it relates to the golf swing. Discussion An overview of the golf swing is described in terms of its potential to cause the frequently noted injuries. Most injuries occur at impact when the golf club hits the ball. This paper concludes that more research into golf-related upper limb injuries is required to develop a thorough understanding of how injuries occur. Types of research include epidemiology studies, kinematic swing analysis and electromyographic studies of the upper limb during golf. By conducting such research, preventative measures maybe developed to reduce golf related injury.

  15. Features of Golf-Related Shoulder Pain in Korean Amateur Golfers. (United States)

    Lee, Chang Hwa; Hong, Jin Young; Jeon, Po Song; Hwang, Ki Hun; Moon, Won Sik; Han, Yong Hyun; Jeong, Ho Joong


    To investigate the causes and characteristics of golf-related shoulder injuries in Korean amateur golfers. Golf-related surveys were administered to, and ultrasonography were conducted on, 77 Korean amateur golfers with golf-related shoulder pain. The correlation between the golf-related surveys and ultrasonographic findings were investigated. The non-dominant shoulder is more likely to have golf-related pain and abnormal findings on ultrasonography than is the dominant shoulder. Supraspinatus muscle tear was the most frequent type of injury on ultrasonography, followed by subscapularis muscle tear. Investigation of the participants' golf-related habits revealed that only the amount of time spent practicing golf was correlated with supraspinatus muscle tear. No correlation was observed between the most painful swing phases and abnormal ultrasonographic findings. Participants who had not previously visited clinics were more likely to present with abnormal ultrasonographic findings, and many of the participants complained of additional upper limb pain. Golf-related shoulder injuries and pain are most likely to be observed in the non-dominant shoulder. The supraspinatus muscle was the most susceptible muscle to damage. A correlation was observed between time spent practicing golf and supraspinatus muscle tear.

  17. Subsidies in Aviation

    Directory of Open Access Journals (Sweden)

    Stefan Gössling


    Full Text Available Relatively little attention has been paid to the existence of subsidies in aviation. As the sector’s importance for economic development is often highlighted, this paper seeks to provide a conceptual overview of the various forms of subsidies in aviation, as a contribution to a more holistic understanding of economic interrelationships. Based on a purposive sampling strategy, existing forms of subsidies are identified and categorized along the value chain. Focus is on industrialized countries, for which more information is available. Results indicate that significant subsidies are extended to manufacturers, infrastructure providers and airlines. These contribute to global economic growth related to aviation, but they also influence capacity in global aviation markets, strengthen the market position of individual airlines, and create conflicts between airlines and the countries they are based in. While the actual scale of subsidies cannot be determined within the scope of this paper, it provides a discussion of options to empirically assess the effects of aviation subsidies on market outcomes. Finally, general conclusions regarding the impact of subsidies on the overall sustainability of the air transport sector are drawn: These include rapidly growing capacity in the aviation system, economic vulnerabilities, and negative climate change related impacts. Results call for a better understanding of the distribution, character and implications of subsidies.

  18. An analysis of peak pelvis rotation speed, gluteus maximus and medius strength in high versus low handicap golfers during the golf swing. (United States)

    Callaway, Sarahann; Glaws, Kate; Mitchell, Melissa; Scerbo, Heather; Voight, Michael; Sells, Pat


    The kinematic sequence of the golf swing is an established principle that occurs in a proximal-to-distal pattern with power generation beginning with rotation of the pelvis. Few studies have correlated the influence of peak pelvis rotation to the skill level of the golfer. Furthermore, minimal research exists on the strength of the gluteal musculature and their ability to generate power during the swing. The purpose of this study was to explore the relationship between peak pelvis rotation, gluteus medius and gluteus maximus strength, and a golfer's handicap. 56 healthy subjects. Each subject was assessed using a hand-held dynamometry device per standardized protocol to determine gluteus maximus and medius strength. The K-vest was placed on the subject with electromagnetic sensors at the pelvis, upper torso, and gloved lead hand to measure the rotational speed at each segment in degrees/second. After K-vest calibration and 5 practice swings, each subject hit 5 golf balls during which time, the sensors measured pelvic rotation speed. A one-way ANOVA was performed to determine the relationships between peak pelvis rotation, gluteus medius and gluteus maximus strength, and golf handicap. A significant difference was found between the following dependent variables and golf handicap: peak pelvis rotation (p=0.000), gluteus medius strength (p=0.000), and gluteus maximus strength (p=0.000). Golfers with a low handicap are more likely to have increased pelvis rotation speed as well as increased gluteus maximus and medius strength when compared to high handicap golfers. The relationships between increased peak pelvis rotation and gluteus maximus and medius strength in low handicap golfers may have implications in designing golf training programs. Further research needs to be conducted in order to further explore these relationships.

  6. A Scoping Review of the Associations of Golf with Eye Injuries in Adults and Children

    Directory of Open Access Journals (Sweden)

    Evan Jenkins


    Full Text Available Introduction. Sport presents a risk of ocular trauma and accounts for a significant number of eye injuries that require hospital admission. The sport of golf presents a risk to eyesight from fast moving objects such as golf clubs and balls. This study aims to investigate the associations of golf with eye injuries and the reasons that these injuries occur. Material/Methods. A literature search was conducted using the databases MEDLINE, Web of Science, SPORTDiscus, and PsycINFO. Grey literature was searched using the WHO international clinical trials registry platform, Google Scholar, and ProQuest. Data was extracted using a standardised form and summarised into a report. Results and Discussion. Twenty-three studies were found relating to eye injuries in golf. Injuries appear to be rare, but more frequent in men and children. Injuries resulted in high rates of enucleation and visual impairment. Children sustained more injury from golf clubs whereas adults sustained more injuries from golf balls. Conclusion. Efforts are needed to encourage golf participants to understand the risks of ocular and indeed other head injuries. Initiatives to provide appropriate supervision and education on this topic are merited. Further research is needed to investigate the circumstances of eye injury in golf and assess the effects of interventions aimed at reducing risk of injury.

    Full Text Available Since labral pathology in professional golfers has been reported, and such pathology has been associated with internal/external hip rotation, quantifying the rotational velocity of the hips during the golf swing may be helpful in understanding the mechanism involved in labral injury. Thus, the purpose of this study was to determine the peak internal/external rotational velocities of the thigh relative to the pelvis during the golf swing. Fifteen female, collegiate golfers participated in the study. Data were acquired through high-speed three dimensional (3-D videography using a multi-segment bilateral marker set to define the segments, while the subjects completed multiple repetitions of a drive. The results indicated that the lead hip peak internal rotational velocity was significantly greater than that of the trail hip external rotational velocity (p = 0.003. It appears that the lead hip of a golfer experiences much higher rotational velocities during the downswing than that of the trail hip. In other structures, such as the shoulder, an increased risk of soft tissue injury has been associated with high levels of rotational velocity. This may indicate that, in golfers, the lead hip may be more susceptible to injury such as labral tears than that of the trailing hip

  13. Peer pressure and thai amateur golfers' gambling on their games: the mediating effect of golf self-efficacy. (United States)

    Ariyabuddhiphongs, Vanchai; Promsakha Na Sakolnakorn, Chomnad


    Our study hypothesizes that Thai amateur golfers gamble on their game because of peer pressure and their golf self-efficacy. To support our hypothesis, we conducted a study to examine the mediating effect of golf self-efficacy on the peer pressure-golf gambling relationship among 387 amateur golfers in Thailand. Peer pressure was operationally defined as fellow players' influence on the individual golfer to gamble; golf self-efficacy as the judgment of the golfer's skills to play golf; and golf gambling as the frequency and amounts of gambling. Regression analysis with bootstrapping was used to test the mediation effect of golf self-efficacy on the peer pressure-golf gambling relationship. The results support our hypothesis; peer pressure predicted golf gambling, and the indirect effect of peer pressure to golf gambling through the mediation of golf self-efficacy was significant. The results support the influence of peer pressure on gambling, and the social cognitive theory reciprocal relationship model.

  20. Electromyographic analysis of the hip and knee during the golf swing. (United States)

    Bechler, J R; Jobe, F W; Pink, M; Perry, J; Ruwe, P A


    As golf increases in popularity, more golfers seek the proper mechanics necessary for the perfect golf swing. Surprisingly little scientific work has been published on the contribution of the hip and knee muscles during the golf swing even though most professionals have recognized their vital contribution. Recent studies have described the electromyographic (EMG) muscle activity of the shoulder, back, and trunk during the golf swing. The purpose of this study was to describe the electrical muscle activity in seven hip and knee muscles of both the left (lead) and right (trail) leg in competitive golfers while performing the golf swing. Sixteen golfers were studied with indwelling electrodes and high-speed cinematography. The EMG was synchronized with the film to discern five phases of the golf swing. Means, SDs, and t-tests were done. The results revealed that the trail hip extensors and abductors in conjunction with the lead adductor magus initiated pelvic rotation during forward swing. The lead hamstrings maintained a flexed knee and provided a stable base on which pelvic rotation took place. The peak EMG muscle activity recorded in the hips and knees occurred in an earlier phase than that measured previously in the trunk and shoulder. This confirmed the sequential firing pattern of the hip and knee muscles that takes place during the competitive golf swing. Information gained from this study can be used by players and coaches to optimize performance and to minimize injury.

  1. The development of human factors research objectives for civil aviation (United States)

    Post, T. J.


    Human factors research programs which would support civil aviation and be suitable for accomplishment by NASA research centers are identified. Aviation problems formed the basis for the research program recommendations and, accordingly, problems were identified, ranked and briefly defined in an informal report to the project monitor and other cognizant NASA personnel. The sources for this problem foundation were literature reviews and extensive interviews with NASA and non-NASA personnel. An overview of these findings is presented.

  2. Suitability of Strain Gage Sensors for Integration into Smart Sport Equipment: A Golf Club Example. (United States)

    Umek, Anton; Zhang, Yuan; Tomažič, Sašo; Kos, Anton


    Wearable devices and smart sport equipment are being increasingly used in amateur and professional sports. Smart sport equipment employs various sensors for detecting its state and actions. The correct choice of the most appropriate sensor(s) is of paramount importance for efficient and successful operation of sport equipment. When integrated into the sport equipment, ideal sensors are unobstructive, and do not change the functionality of the equipment. The article focuses on experiments for identification and selection of sensors that are suitable for the integration into a golf club with the final goal of their use in real time biofeedback applications. We tested two orthogonally affixed strain gage (SG) sensors, a 3-axis accelerometer, and a 3-axis gyroscope. The strain gage sensors are calibrated and validated in the laboratory environment by a highly accurate Qualisys Track Manager (QTM) optical tracking system. Field test results show that different types of golf swing and improper movement in early phases of golf swing can be detected with strain gage sensors attached to the shaft of the golf club. Thus they are suitable for biofeedback applications to help golfers to learn repetitive golf swings. It is suggested that the use of strain gage sensors can improve the golf swing technical error detection accuracy and that strain gage sensors alone are enough for basic golf swing analysis. Our final goal is to be able to acquire and analyze as many parameters of a smart golf club in real time during the entire duration of the swing. This would give us the ability to design mobile and cloud biofeedback applications with terminal or concurrent feedback that will enable us to speed-up motor skill learning in golf.

    Full Text Available Investment in the real estate sector has a great risk, therefore a developer needs to do investment analysis before making a decision. The decision is made by considering the returns from two investment alternatives. The first alternative examined is a 9-hole golf course and housing in proximity to the golf. The second alternative is residential property. Given the above conditions, the purpose of this research is to help the developer to make the proper investment decision, based on which alternative has the higher return. Two data collection methods are used in this research, including interviews and a survey which was done by distributing questionnaires to develop a profile of golfers and purchasers as well as potential residential purchasers. Forecasting analysis using the Holt-Winters model was used for forecasting the number of golfers. The Box-Jenkins model was utilized to forecast residential sales. The forecasting results were used for cash flow analysis. The results show that the first alternative produces a higher IRR (25,16% per year and NPV of Rp.25.056.800.000 , relative to the the second alternative with an IRR of 16,72% per year and NPV of Rp.4.794.945.000.

  7. National volcanic ash operations plan for aviation (United States)

    ,; ,


    The National Aviation Weather Program Strategic Plan (1997) and the National Aviation Weather Initiatives (1999) both identified volcanic ash as a high-priority informational need to aviation services. The risk to aviation from airborne volcanic ash is known and includes degraded engine performance (including flameout), loss of visibility, failure of critical navigational and operational instruments, and, in the worse case, loss of life. The immediate costs for aircraft encountering a dense plume are potentially major—damages up to $80 million have occurred to a single aircraft. Aircraft encountering less dense volcanic ash clouds can incur longer-term costs due to increased maintenance of engines and external surfaces. The overall goal, as stated in the Initiatives, is to eliminate encounters with ash that could degrade the in-flight safety of aircrews and passengers and cause damage to the aircraft. This goal can be accomplished by improving the ability to detect, track, and forecast hazardous ash clouds and to provide adequate warnings to the aviation community on the present and future location of the cloud. To reach this goal, the National Aviation Weather Program established three objectives: (1) prevention of accidental encounters with hazardous clouds; (2) reduction of air traffic delays, diversions, or evasive actions when hazardous clouds are present; and (3) the development of a single, worldwide standard for exchange of information on airborne hazardous materials. To that end, over the last several years, based on numerous documents (including an OFCMsponsored comprehensive study on aviation training and an update of Aviation Weather Programs/Projects), user forums, and two International Conferences on Volcanic Ash and Aviation Safety (1992 and 2004), the Working Group for Volcanic Ash (WG/VA), under the OFCM-sponsored Committee for Aviation Services and Research, developed the National Volcanic Ash Operations Plan for Aviation and Support of the

In the never ending pursuit of lower costs, the Thermal Imaging offers shorter inspection times thanks to its application in aircraft inspections and can reduce the number of costly goarounds using the Enhanced Vision System, which also increases safety in one of the most dangerous parts of flight. Thermal Imaging also offers solutions for Airport Perimeter Security and it can be used for construction of ground surveillance system.

  9. Alcohol and civil aviation. (United States)

    Holdener, F


    In aviation medicine until the early 1960s the idea that pilots would fly while under the influence of alcohol was taboo. In the United States of America, the taboo was broken when it became known that 30% of fatally injured pilots in general aviation had been under the influence of alcohol. Since then the rate has declined to 10%. No fatal accidents involving alcohol have been recorded in airline passenger transport. The prevalence of pilots flying under the influence of alcohol is unknown. The lowest studied blood alcohol concentration (BAC) with impaired flying skill today is 0.025%, effectively suggesting that the permitted level should be zero, but many aviation authorities have not yet translated such findings into rules and regulations. In the early 1970s the US Federal Air Surgeon began to re-issue licences for rehabilitated alcoholic pilots. Previously alcoholism had been a reason for mandatory permanent grounding. The possibility of returning to the cockpit first opened the way to early recognition of alcoholic pilots on a larger scale. Today many airlines have their own alcohol programmes. This paper gives a brief account of the Swissair programme with its four phases: observation, intervention, treatment and follow-up.

  19. Entrepreneurship within General Aviation (United States)

    Ullmann, Brian M.


    Many modern economic theories place great importance upon entrepreneurship in the economy. Some see the entrepreneur as the individual who bears risk of operating a business in the face of uncertainty about future conditions and who is rewarded through profits and losses. The 20th century economist Joseph Schumpter saw the entrepreneur as the medium by which advancing technology is incorporated into society as businesses seek competitive advantages through more efficient product development processes. Due to the importance that capitalistic systems place upon entrepreneurship, it has become a well studied subject with many texts to discuss how entrepreneurs can succeed in modern society. Many entrepreneuring and business management courses go so far as to discuss the characteristic phases and prominent challenges that fledgling companies face in their efforts to bring a new product into a competitive market. However, even with all of these aids, start-up companies fail at an enormous rate. Indeed, the odds of shepherding a new company through the travails of becoming a well established company (as measured by the ability to reach Initial Public Offering (IPO)) have been estimated to be six in 1,000,000. Each niche industry has characteristic challenges which act as barriers to entry for new products into that industry. Thus, the applicability of broad generalizations is subject to limitations within niche markets. This paper will discuss entrepreneurship as it relates to general aviation. The goals of this paper will be to: introduce general aviation; discuss the details of marrying entrepreneurship with general aviation; and present a sample business plan which would characterize a possible entrepreneurial venture.

  20. Technology outlook for aviation (United States)

    Roberts, L.


    Growth projections for aviation technology are put forth for a quarter-century ahead. Three main trends envisaged are towards: great efficiency and economy and longer range and endurance for subsonic aircraft; new generations of short-range fixed-wing craft and rotorcraft with versatile applicability; supersonic and hypersonic speeds. Improvements in lift/drag ratio, specific fuel consumption, structural weight factor, aerodynamic improvements (laminar flow control, increased wing aspect ratio, drag reduction for specified lift, propulsion efficiency, higher bypass ratios, composite structures) are discussed along with V/STOL, controllable twist rotors, circulation control rotors, variable-cycle engines, and higher structural efficiencies.

  7. The lumbar spine and low back pain in golf: a literature review of swing biomechanics and injury prevention. (United States)

    Gluck, George S; Bendo, John A; Spivak, Jeffrey M


    The golf swing imparts significant stress on the lumbar spine. Not surprisingly, low back pain (LBP) is one of the most common musculoskeletal complaints among golfers. This article provides a review of lumbar spine forces during the golf swing and other research available on swing biomechanics and muscle activity during trunk rotation. The role of "modern" and "classic" swing styles in golf-associated LBP, as well as LBP causation theories, treatment, and prevention strategies, are reviewed. A PubMed literature search was performed using various permutations of the following keywords: lumbar, spine, low, back, therapy, pain, prevention, injuries, golf, swing, trunk, rotation, and biomechanics. Articles were screened and selected for relevance to injuries in golf, swing mechanics, and biomechanics of the trunk and lumbar spine. Articles addressing treatment of LBP with discussions on trunk rotation or golf were also selected. Primary references were included from the initial selection of articles where appropriate. General web searches were performed to identify articles for background information on the sport of golf and postsurgical return to play. Prospective, randomized studies have shown that focus on the transversus abdominus (TA) and multifidi (MF) muscles is a necessary part of physical therapy for LBP. Some studies also suggest that the coaching of a "classic" golf swing and increasing trunk flexibility may provide additional benefit. There is a notable lack of studies separating the effects of swing modification from physical rehabilitation, and controlled trials are necessary to identify the true effectiveness of specific swing modifications for reducing LBP in golf. Although the establishment of a commonly used regimen to address all golf-associated LBP would be ideal, it may be more practical to apply basic principles mentioned in this article to the tailoring of a unique regimen for the patient. Guidelines for returning to golf after spine surgery are

  8. Design and fabrication hazard stakes golf course polymeric foam material empty bunch (EFB) fiber reinforced (United States)

    Zulfahmi; Syam, B.; Wirjosentono, B.


    A golf course with obstacles in the forms of water obstacle and lateral water obstacle marked with the stakes which are called golf course obstacle stake in this study. This study focused on the design and fabrication of the golf course obstacle stake with a solid cylindrical geometry using EFB fiber-reinforced polimeric foam composite materials. To obtain the EFB fiber which is free from fat content and other elements, EFB is soaked in the water with 1% (of the watre total volume) NaOH. The model of the mould designed is permanent mould that can be used for the further refabrication process. The mould was designed based on resin-compound paste materials with talc powder plus E-glass fiber to make the mould strong. The composition of polimeric foam materials comprised unsaturated resin Bqtn-Ex 157 (70%), blowing agent (10%), fiber (10%), and catalyst (10%). The process of casting the polimeric foam composit materials into the mould cavity should be at vertical casting position, accurate interval time of material stirring, and periodical casting. To find out the strength value of the golf course obstacle stake product, a model was made and simulated by using the software of Ansys workbench 14.0, an impact loading was given at the height of 400 mm and 460 mm with the variation of golf ball speed (USGA standard) v = 18 m/s, v = 35 m/s, v = 66.2 m/s, v = 70 m/s, and v = 78.2 m/s. The clarification showed that the biggest dynamic explicit loading impact of Fmax = 142.5 N at the height of 460 mm with the maximum golf ball speed of 78.2 m/s did not experience the hysteresis effect and inertia effect. The largest deformation area occurred at the golf ball speed v = 66.2 mm/s, that is 18.029 mm (time: 2.5514e-004) was only concentrated around the sectional area of contact point of impact, meaning that the golf course obstacle stakes made of EFB fiber-reinforced polymeric foam materials have the geometric functional strength that are able to absorb the energy of golf ball

  9. Suitability of golf course ponds for amphibian metamorphosis when bullfrogs are removed. (United States)

    Boone, Michelle D; Semlitsch, Raymond D; Mosby, Cory


    Managing areas designed for human recreation so that they are compatible with natural amphibian populations can reduce the negative impacts of habitat destruction. We examined the potential for amphibians to complete larval development in golf course ponds in the presence or absence of overwintered bullfrog tadpoles (Rana catesbeiana), which are frequently found in permanent, human-made ponds. We reared larval American toads (Bufo americanus), southern leopard frogs (R. sphenocephala), and spotted salamanders (Ambystoma maculatum) with 0 or 5 overwintered bullfrog tadpoles in field enclosures located in ponds on golf courses or in experimental wetlands at a reference site. Survival to metamorphosis of American toads, southern leopard frogs, and spotted salamanders was greater in ponds on golf courses than at reference sites. We attributed this increased survival to low abundance of insect predators in golf course ponds. The presence of overwintered bullfrogs, however, reduced the survival of American toads, southern leopard frogs, and spotted salamanders reared in golf course ponds, indicating that the suitability of the aquatic habitats for these species partly depended on the biotic community present. Our results suggest that ponds in human recreational areas should be managed by maintaining intermediate hydroperiods, which will reduce the presence of bullfrog tadpoles and predators, such as fish, and which may allow native amphibian assemblages to flourish.

  15. Development of a Methodology for Strategic Environmental Assessment: Application to the Assessment of Golf Course Installation Policy in Taiwan (United States)

    Chen, Ching-Ho; Wu, Ray-Shyan; Liu, Wei-Lin; Su, Wen-Ray; Chang, Yu-Min


    Some countries, including Taiwan, have adopted strategic environmental assessment (SEA) to assess and modify proposed policies, plans, and programs (PPPs) in the planning phase for pursuing sustainable development.

    Some countries, including Taiwan, have adopted strategic environmental assessment (SEA) to assess and modify proposed policies, plans, and programs (PPPs) in the planning phase for pursuing sustainable development. However, there were only some sketchy steps focusing on policy assessment in the system of Taiwan. This study aims to develop a methodology for SEA in Taiwan to enhance the effectiveness associated with PPPs. The proposed methodology comprises an SEA procedure involving PPP management and assessment in various phases, a sustainable assessment framework, and an SEA management system.

  19. Launch Velocities in Successful Golf Putting: An Analytical Analysis

    Directory of Open Access Journals (Sweden)

    John F. Mahoney


    Full Text Available Background: This study is concerned with the special case of a putted ball intersecting a standard golf hole at its diameter. The velocity of the ball at the initial rim of the hole is termed the launch velocity and depending upon its value the ball may either be captured or it may escape capture by jumping over the hole. The critical value of the launch velocity (V is such that lesser values result in capture while greater values produce escape. Purpose: Since the value of the V entered prominently in some theoretical studies of putting, the aim of the current study is to provide an original re-evaluation of V and to contrast our results with existing results. Method: This analytical analysis relies on trigonometry in conjunction with Newtonian mechanics and the mathematics of projectiles. The results of a recent study into the mathematics of a bouncing ball which included the notions of restitution and friction were also employed in the analysis. Results: If bouncing and slipping do not occur when the ball hits the far rim of the hole our analysis produces a value of V of 1.356 m/s. When bouncing and slipping are present we find that V is at least 1.609 m/s but increases beyond this value as slipping and friction become greater. Useful relations which relate the dynamics and geometry of the ball to V are provided. Conclusion: Since ambient conditions may influence the extent of bounce and slippage we conjecture that the value of V is not unique.

  5. High resolution electrical resistivity tomography of golf course greens irrigated with reclaimed wastewater: Hydrological approach (United States)

    Tapias, Josefina C.; Lovera, Raúl; Himi, Mahjoub; Gallardo, Helena; Sendrós, Alexandre; Marguí, Eva; Queralt, Ignasi; Casas, Albert


    Actually, there are over 300 golf courses and more than three thousand licensed players in Spain. For this reason golf cannot be considered simply a hobby or a sport, but a very significant economic activity. Considered as one of the most rapidly expanding land-use and water demanding business in the Mediterranean, golf course development generates controversy. In the recent years there has been a considerable demand for golf courses to adopt environmentally sustainable strategies and particularly water authorities are forcing by law golf managers to irrigate with alternative water resources, mainly reclaimed wastewater. Watering practices must be based on soil properties that are characterized by samples removed from the different zones of the golf course and submitted to an accredited physical soil testing laboratory. Watering schedules are critical on greens with poor drainage or on greens with excessively high infiltration rates. The geophysical survey was conducted over the greens of the Girona Golf Club. Eighteen electrical resistivity tomographies were acquired using a mixed Wenner-Schlumberger configuration with electrodes placed 0.5 meter apart. Small stainless-steel nails were used as electrodes to avoid any damage in the fine turfgrass of greens The resistivity meter was set for systematically and automatically selects current electrodes and measurement electrodes to sample apparent resistivity values. Particle size analysis (PSA) has been performed on soil materials of any putting green. The PSA analysis has been composed of two distinct phases. The first has been the textural analysis of the soils for determining the content of sand, silt, and clay fraction via the use of a stack of sieves with decreasing sized openings from the top sieve to the bottom. Subsequently, the hydraulic conductivity of the substrates has been evaluated by means of Bredding and Hazen empirical relationships. The results of this research show that the electrical resistivity

  6. The Golf Ball Sign: Arthroscopic Localization of an Osteochondritis Dissecans Lesion of the Knee


    Piposar, Jonathan; Sutton, Karen


    We report on the arthroscopic treatment of a 12-year-old boy diagnosed with an osteochondral defect of the medial femoral condyle. He underwent arthroscopic fixation of the defect, and during the surgery, a blunt trocar was used to localize the lesion. The trocar created a transient dimpling effect on the cartilage overlying the osteochondral defect that resembled the surface of a golf ball. This “golf ball sign” then served as a visual guide during placement of a chondral dart. When present,...

  7. General aviation design synthesis utilizing interactive computer graphics (United States)

    Galloway, T. L.; Smith, M. R.


    Interactive computer graphics is a fast growing area of computer application, due to such factors as substantial cost reductions in hardware, general availability of software, and expanded data communication networks. In addition to allowing faster and more meaningful input/output, computer graphics permits the use of data in graphic form to carry out parametric studies for configuration selection and for assessing the impact of advanced technologies on general aviation designs. The incorporation of interactive computer graphics into a NASA developed general aviation synthesis program is described, and the potential uses of the synthesis program in preliminary design are demonstrated.

  8. Volcanic hazards and aviation safety (United States)

    Casadevall, Thomas J.; Thompson, Theodore B.; Ewert, John W.; ,


    An aeronautical chart was developed to determine the relative proximity of volcanoes or ash clouds to the airports and flight corridors that may be affected by volcanic debris. The map aims to inform and increase awareness about the close spatial relationship between volcanoes and aviation operations. It shows the locations of the active volcanoes together with selected aeronautical navigation aids and great-circle routes. The map mitigates the threat that volcanic hazards pose to aircraft and improves aviation safety.

  9. The Council on Aviation Accreditation: Part One - Historical Foundation (United States)

    Prather, C. Daniel


    The Council on Aviation Accreditation (CAA) was established in 1988 in response to the need for formal, specialized accreditation of aviation academic programs, as expressed by institutional members of the University Aviation Association (UAA). The first aviation programs were accredited by the CAA in 1992, and today, the CAA lists 60 accredited programs at 21 institutions nationwide. Although the number of accredited programs has steadily grown, there are currently only 20 percent of UAA member institutions with CAA accredited programs. In an effort to further understand this issue, a case study of the CAA was performed, which resulted in a two-part case study report. Part one focuses on the following questions: (a) why was the CAA established and how has it evolved; (b) what is the purpose of the CAA; (c) how does a program become accredited by the CAA; and (d) what is the current environment in which the CAA operates. In answering these questions, various sources of data (such as CAA documents, magazine and journal articles, email inquiries, and an on-line survey) were utilized. Part one of this study resulted in a better understanding of the CAA, including its history, purpose, and the entire accreditation process. Part two will both examine the contemporary issues being faced by the CAA and provide recommendations to enhance the future growth of the organization.

  13. Cyber threats within civil aviation (United States)

    Heitner, Kerri A.

    Existing security policies in civil aviation do not adequately protect against evolving cyber threats. Cybersecurity has been recognized as a top priority among some aviation industry leaders. Heightened concerns regarding cyber threats and vulnerabilities surround components utilized in compliance with the Federal Aviation Administration's (FAA) Next Generation Air Transportation (NextGen) implementation. Automated Dependent Surveillance-B (ADS-B) and Electronic Flight Bags (EFB) have both been exploited through the research of experienced computer security professionals. Civil aviation is essential to international infrastructure and if its critical assets were compromised, it could pose a great risk to public safety and financial infrastructure. The purpose of this research was to raise awareness of aircraft system vulnerabilities in order to provoke change among current national and international cybersecurity policies, procedures and standards. Although the education of cyber threats is increasing in the aviation industry, there is not enough urgency when creating cybersecurity policies. This project intended to answer the following questions: What are the cyber threats to ADS-B of an aircraft in-flight? What are the cyber threats to EFB? What is the aviation industry's response to the issue of cybersecurity and in-flight safety? ADS-B remains unencrypted while the FAA's mandate to implement this system is rapidly approaching. The cyber threat of both portable and non-portable EFB's have received increased publicity, however, airlines are not responding quick enough (if at all) to create policies for the use of these devices. Collectively, the aviation industry is not being proactive enough to protect its aircraft or airport network systems. That is not to say there are not leaders in cybersecurity advancement. These proactive organizations must set the standard for the future to better protect society and it's most reliable form of transportation.

  15. Assessment of management of a golf course by means of sustainability indicators

    Directory of Open Access Journals (Sweden)

    Gaio Cesare Pacini


    Full Text Available Golf courses are supposed to produce remarkable negative effects on the environment, due to some techniques involved in their management. To provide data useful for the proper assessment of the agro-environmental sustainability of a golf course, the framework agro-environmental sustainability information system (AESIS was used, utilizing a set of indicators suitable to evaluate different dimensions of sustainability (physical, ecological, productive and social. The management of areal golf course located in Tuscany (central Italy was compared to an alternative land use of the same area represented by an ordinary farm based on a sunflower-wheat rotation. Assessment indicators were selected by applying a conceptual model based on ecology theory and were calculated considering site-specific production and pedo-climatic features of the area. Different weighting scenarios were hypothesized in order to have different management options assessed and to carry out a targeted sensitivity analysis. Main results confirmed the significant impact of golf management on some ecological characteristics but the holistic assessment of AESIS approach permitted an overall evaluation that comprised a wide range of different issues. AESIS demonstrated to be a practical and adaptive tool able to perform an efficient comparison of possible land destinations.

  19. Estimation of Center of Mass Trajectory using Wearable Sensors during Golf Swing. (United States)

    Najafi, Bijan; Lee-Eng, Jacqueline; Wrobel, James S; Goebel, Ruben


    This study suggests a wearable sensor technology to estimate center of mass (CoM) trajectory during a golf swing. Groups of 3, 4, and 18 participants were recruited, respectively, for the purpose of three validation studies. Study 1 examined the accuracy of the system to estimate a 3D body segment angle compared to a camera-based motion analyzer (Vicon®). Study 2 assessed the accuracy of three simplified CoM trajectory models. Finally, Study 3 assessed the accuracy of the proposed CoM model during multiple golf swings. A relatively high agreement was observed between wearable sensors and the reference (Vicon®) for angle measurement (r > 0.99, random error 0.93 v. r = 0.52, respectively). On the same note, the proposed two-link model estimated CoM trajectory during golf swing with relatively good accuracy (r > 0.9, A-P random error wearable technology based on inertial sensors are accurate to estimate center of mass trajectory in complex athletic task (e.g., golf swing)This study suggests that two-link model of human body provides optimum tradeoff between accuracy and minimum number of sensor module for estimation of center of mass trajectory in particular during fast movements.Wearable technologies based on inertial sensors are viable option for assessing dynamic postural control in complex task outside of gait laboratory and constraints of cameras, surface, and base of support.

  20. Grating Oriented Line-Wise Filtration (GOLF) for Dual-Energy X-ray CT (United States)

    Xi, Yan; Cong, Wenxiang; Harrison, Daniel; Wang, Ge


    In medical X-ray Computed Tomography (CT), the use of two distinct X-ray source spectra (energies) allows dose-reduction and material discrimination relative to that achieved with only one source spectrum. Existing dual-energy CT methods include source kVp-switching, double-layer detection, dual-source gantry, and two-pass scanning. Each method suffers either from strong spectral correlation or patient-motion artifacts. To simultaneously address these problems, we propose to improve CT data acquisition with the Grating Oriented Line-wise Filtration (GOLF) method, a novel X-ray filter that is placed between the source and patient. GOLF uses a combination of absorption and filtering gratings that are moved relative to each other and in synchronization with the X-ray tube kVp-switching process and/or the detector view-sampling process. Simulation results show that GOLF can improve the spectral performance of kVp-switching to match that of dual-source CT while avoiding patient motion artifacts and dual imaging chains. Although significant flux is absorbed by this pre-patient filter, the proposed GOLF method is a novel path for cost-effectively extracting dual-energy or multi-energy data and reducing radiation dose with or without kVp switching.

  3. Kinetic and Kinematic Differences in a Golf Swing in One and Both Lower Limb Amputees

    Directory of Open Access Journals (Sweden)

    Stastny Petr


    Full Text Available Amputee golfers need to cope with the absence of sole proprioception, a decreased range of swing motion and other factors which should be recognized for training purposes. The aim of this study was to determine the kinetic and kinematic differences in the golf swing in one leg and two legs amputees. The participants consisted of two males and one female at a professional or amateur level with a different degree of disability. Each participant was taped by 3D markers and performed five golf swings with the iron 6. The intraclass correlation coefficient (ICC did not vary between individuals in kinematics, however, it was low in kinetic variables of two leg amputees. The Kendal rank correlation showed a significant relationship between the level of amputation and a large number of kinetic and kinematic variables such as X factor, O factor, S factor and individual body angles. The fluency and similarity of the golf swing did not depend on the level of amputation. One lower limb amputation did not seem to increase movement variability contrary to two lower limb amputation. The most variable parameter was a weight-shift in all golfers. The takeaway and horizontal force angle depended on the level of amputation rather than individual technique, thus, their modification by training may be difficult. Estimation of golf swing „mistakes“ in amputees in respect to the leading arm in an early follow or late follow position appeared to be useless.

  4. Performance processes within affect-related performance zones: a multi-modal investigation of golf performance. (United States)

    van der Lei, Harry; Tenenbaum, Gershon


    Individual affect-related performance zones (IAPZs) method utilizing Kamata et al. (J Sport Exerc Psychol 24:189-208, 2002) probabilistic model of determining the individual zone of optimal functioning was utilized as idiosyncratic affective patterns during golf performance. To do so, three male golfers of a varsity golf team were observed during three rounds of golf competition. The investigation implemented a multi-modal assessment approach in which the probabilistic relationship between affective states and both, performance process and performance outcome, measures were determined. More specifically, introspective (i.e., verbal reports) and objective (heart rate and respiration rate) measures of arousal were incorporated to examine the relationships between arousal states and both, process components (i.e., routine consistency, timing), and outcome scores related to golf performance. Results revealed distinguishable and idiosyncratic IAPZs associated with physiological and introspective measures for each golfer. The associations between the IAPZs and decision-making or swing/stroke execution were strong and unique for each golfer. Results are elaborated using cognitive and affect-related concepts, and applications for practitioners are provided.

  8. Skin cancer prevention and detection campaign at golf courses on Spain's Costa del Sol. (United States)

    del Boz, J; Fernández-Morano, T; Padilla-España, L; Aguilar-Bernier, M; Rivas-Ruiz, F; de Troya-Martín, M


    Skin cancer prevention and detection campaigns targeting specific groups are necessary and have proven to be more effective than those aimed at the general population. Interventions in outdoor tourist spots have proven successful, although none have specifically targeted golf courses. The aims of this study were to describe the risk profile of golfers and golf course workers and evaluate the impact of a skin cancer prevention and early detection intervention. This was a cross-sectional descriptive study conducted at 6 golf courses. The intervention included a skin examination and completion of a questionnaire about demographic details, risk factors, and sun exposure and sun protection habits. Participants were also given advice on sun protection measures, self-examination, and use of sunscreens, and were asked about their satisfaction with the intervention and their intention to change their current behaviors. The effect was measured in terms of the diagnoses made, satisfaction with the intervention, reported intention to change, and potential effect in terms of existing risk factors. Of the 351 participants (57% golfers and 43% golf course workers), 70.4% had fair skin, 11.7% had a family history of skin cancer, and 8.5% had a personal history of skin cancer. Skin cancer and actinic keratoses were diagnosed in 10.7% and 40% of the golfers, respectively. The session was rated positively by 99.4% of the participants; 93.9% stated that they intended to improve their sun exposure habits and 93.4% said that they planned to examine their skin more frequently. Our findings confirm that golf course workers and, in particular, golfers are an important target for skin cancer prevention campaigns. This is the first intervention to specifically target golf courses, and it proved to be both feasible and useful. Its success appears to be attributable to numerous factors: it was conducted at golf courses, had multiple components, and was preceded by a motivational campaign

  10. Golf Course Irrigation with Reclaimed Water in the Mediterranean: A Risk Management Matter

    Directory of Open Access Journals (Sweden)

    Miquel Salgot


    Full Text Available Controversy regarding the amount of water consumed or saved as a result of human activity is currently paramount in water-scarce areas. In recent decades, golf—a land and water consuming activity—has been implanted in several areas of the Mediterranean basin, where the scarcity of water resources is well-known. As a result, the use of conventional water resources for golf course irrigation is increasingly contested and its replacement by reclaimed water has become essential. This paper examines the wide range of issues involved in its use on golf courses, including hazards—due to the presence of microorganisms and pollutants—and the corresponding risks that can appear. The resulting biological, chemical and physical water quality concerns are analyzed. Legal aspects related to the use of reclaimed water are also discussed and good reuse practices are suggested, including a detailed examination of risk assessment procedures and tools through observation or chemical, physical and microbiological analysis. The HACCP system—which focuses on quality determination in water samples from relevant control points—is described in detail, as it is generally accepted as one of the most scientific ways to detect health problems on a golf course. The paper concludes that, given the increasing availability of treated and reclaimed water and the water needs of golf courses, the future development of the sport in areas without surplus water resources—such as the Mediterranean basin—will predictably depend upon the use of reclaimed water. In recent years, risk assessment or analysis has emerged as an essential tool to guarantee the application of reclaimed water at an acceptable risk level. There certainly have been considerable advances and improvements in the tools that guarantee the safe use of reclaimed water, although current methods available require simplification for their practical application. Nevertheless, protocols applied at present

  11. The development and validation of a golf swing and putt skill assessment for children. (United States)

    Barnett, Lisa M; Hardy, Louise L; Brian, Ali S; Robertson, Sam


    The aim was to describe development of a process-oriented instrument designed to assess the golf swing and putt stroke, and to assess the instrument's discriminative validity in terms of age and reliability (intra-rater and re-test). A Delphi consultation (with golf industry professionals and researchers in movement skill assessment) was used to develop an assessment for each skill based on existing skill assessment protocols. Each skill had six components to be marked as present/absent. Individual scores were based on the number of performance components successfully demonstrated over two trials for each skill (potential score range 0 to 24). Children (n = 43) aged 6-10 years (M = 7.8 years, SD = 1.3) were assessed in both skills live in the field by one rater at Time 1(T1). A subset of children (n = 28) had consent for assessments to be videoed. Six weeks later 19 children were reassessed, five days apart (T2, T3). An ANOVA assessed discriminative validity i.e. whether skill competence at T1 differed by age (6 years, 7/8 years and 9/10 years). Intraclass correlations (ICC) assessed intra-rater reliability between the live and video assessment at T1 and test-retest reliability (between T2 and T3). Paired t-tests assessed any systematic differences between live and video assessments (T1) and between T2 and T3. Older children were more skilled (F (2, 40) = 11.18, p skill deficits, mastery level, and talent identification in beginner young golf players.Process rather than product oriented outcomes better identify areas of skill deficit in young children.The proposed swing and putt instrument can reliably identify skill deficits in children of elementary school age who are new to golf and can be used by a range of stakeholders including golf coaches, generalist sport coaches and physical education teachers.

  12. Assessment of the Potential of UAV Video Image Analysis for Planning Irrigation Needs of Golf Courses

    Directory of Open Access Journals (Sweden)

    Alberto-Jesús Perea-Moreno


    Full Text Available Golf courses can be considered as precision agriculture, as being a playing surface, their appearance is of vital importance. Areas with good weather tend to have low rainfall. Therefore, the water management of golf courses in these climates is a crucial issue due to the high water demand of turfgrass. Golf courses are rapidly transitioning to reuse water, e.g., the municipalities in the USA are providing price incentives or mandate the use of reuse water for irrigation purposes; in Europe this is mandatory. So, knowing the turfgrass surfaces of a large area can help plan the treated sewage effluent needs. Recycled water is usually of poor quality, thus it is crucial to check the real turfgrass surface in order to be able to plan the global irrigation needs using this type of water. In this way, the irrigation of golf courses does not detract from the natural water resources of the area. The aim of this paper is to propose a new methodology for analysing geometric patterns of video data acquired from UAVs (Unmanned Aerial Vehicle using a new Hierarchical Temporal Memory (HTM algorithm. A case study concerning maintained turfgrass, especially for golf courses, has been developed. It shows very good results, better than 98% in the confusion matrix. The results obtained in this study represent a first step toward video imagery classification. In summary, technical progress in computing power and software has shown that video imagery is one of the most promising environmental data acquisition techniques available today. This rapid classification of turfgrass can play an important role for planning water management.

  13. A psychologist's view of validating aviation systems (United States)

    Stein, Earl S.; Wagner, Dan


    All systems, no matter what they are designed to do, have shortcomings that may make them less productive than was hoped during the initial development. Such shortcomings can arise at any stage of development: from conception to the end of the implementation life cycle. While systems failure and errors of a lesser magnitude can occur as a function of mechanical or software breakdown, the majority of such problems, in aviation are usually laid on the shoulders of the human operator and, to a lesser extent, on human factors. The operator bears the responsibility and blame even though, from a human factors perspective, error may have been designed into the system. Human factors is not a new concept in aviation. The name may be new, but the issues related to operators in the loop date back to the industrial revolution of the nineteenth century and certainly to the aviation build-up for World War I. During this first global confrontation, military services from all sides discovered rather quickly that poor selection and training led to drastically increased personnel losses. While hardware design became an issue later, the early efforts were primarily focused on increased care in pilot selection and on their training. This actually involved early labor-intensive simulation, using such devices as sticks and chairs mounted on rope networks which could be manually moved in response to control input. The use of selection criteria and improved training led to more viable person-machine systems. More pilots survived training and their first ten missions in the air, a rule of thumb arrived at by experience which predicted ultimate survival better than any other. This rule was to hold through World War II. At that time, personnel selection and training became very sophisticated based on previous standards. Also, many psychologists were drafted into Army Air Corps programs which were geared towards refining the human factor. However, despite the talent involved in these programs

  14. Distributed Aviation Concepts and Technologies (United States)

    Moore, Mark D.


    Aviation has experienced one hundred years of evolution, resulting in the current air transportation system dominated by commercial airliners in a hub and spoke infrastructure. While the first fifty years involved disruptive technologies that required frequent vehicle adaptation, the second fifty years produced a stable evolutionary optimization of decreasing costs with increasing safety. This optimization has resulted in traits favoring a centralized service model with high vehicle productivity and cost efficiency. However, it may also have resulted in a system that is not sufficiently robust to withstand significant system disturbances. Aviation is currently facing rapid change from issues such as environmental damage, terrorism threat, congestion and capacity limitations, and cost of energy. Currently, these issues are leading to a loss of service for weaker spoke markets. These catalysts and a lack of robustness could result in a loss of service for much larger portions of the aviation market. The impact of other competing transportation services may be equally important as casual factors of change. Highway system forecasts indicate a dramatic slow down as congestion reaches a point of non-linearly increasing delay. In the next twenty-five years, there is the potential for aviation to transform itself into a more robust, scalable, adaptive, secure, safe, affordable, convenient, efficient and environmentally friendly system. To achieve these characteristics, the new system will likely be based on a distributed model that enables more direct services. Short range travel is already demonstrating itself to be inefficient with a centralized model, providing opportunities for emergent distributed services through air-taxi models. Technologies from the on-demand revolution in computers and communications are now available as major drivers for aviation on-demand adaptation. Other technologies such as electric propulsion are currently transforming the automobile

  10. Electromyographic Patterns during Golf Swing: Activation Sequence Profiling and Prediction of Shot Effectiveness

    Directory of Open Access Journals (Sweden)

    Antanas Verikas


    Full Text Available This study analyzes muscle activity, recorded in an eight-channel electromyographic (EMG signal stream, during the golf swing using a 7-iron club and exploits information extracted from EMG dynamics to predict the success of the resulting shot. Muscles of the arm and shoulder on both the left and right sides, namely flexor carpi radialis, extensor digitorum communis, rhomboideus and trapezius, are considered for 15 golf players (∼5 shots each. The method using Gaussian filtering is outlined for EMG onset time estimation in each channel and activation sequence profiling. Shots of each player revealed a persistent pattern of muscle activation. Profiles were plotted and insights with respect to player effectiveness were provided. Inspection of EMG dynamics revealed a pair of highest peaks in each channel as the hallmark of golf swing, and a custom application of peak detection for automatic extraction of swing segment was introduced. Various EMG features, encompassing 22 feature sets, were constructed. Feature sets were used individually and also in decision-level fusion for the prediction of shot effectiveness. The prediction of the target attribute, such as club head speed or ball carry distance, was investigated using random forest as the learner in detection and regression tasks. Detection evaluates the personal effectiveness of a shot with respect to the player-specific average, whereas regression estimates the value of target attribute, using EMG features as predictors. Fusion after decision optimization provided the best results: the equal error rate in detection was 24.3% for the speed and 31.7% for the distance; the mean absolute percentage error in regression was 3.2% for the speed and 6.4% for the distance. Proposed EMG feature sets were found to be useful, especially when used in combination. Rankings of feature sets indicated statistics for muscle activity in both the left and right body sides, correlation-based analysis of EMG

  11. Aviation Medicine: global historical perspectives and the development of Aviation Medicine alongside the growth of Singapore's aviation landscape. (United States)

    Gan, W H; Low, R; Singh, J


    Aviation Medicine traces its roots to high altitude physiology more than 400 years ago. Since then, great strides have been made in this medical specialty, initially catalysed by the need to reduce pilot medical attrition during the World Wars, and more recently, fuelled by the explosive growth in globalised commercial air travel. This paper traces the historical milestones in Aviation Medicine, and maps its development in Singapore since the 1960s. Advancements in military aviation platforms and technology as well as the establishment of Singapore as an international aviation hub have propelled Aviation Medicine in Singapore to the forefront of many domains. These span Aviation Physiology training, selection medical standards, performance maximisation, as well as crew and passenger protection against communicable diseases arising from air travel. The year 2011 marks the centennial milestone of the first manned flight in Singapore, paving the way for further growth of Aviation Medicine as a mature specialty in Singapore.

  14. Putting like a pro: the role of positive contagion in golf performance and perception.

    Directory of Open Access Journals (Sweden)

    Charles Lee

    Full Text Available Many amateur athletes believe that using a professional athlete's equipment can improve their performance. Such equipment can be said to be affected with positive contagion, which refers to the belief of transference of beneficial properties between animate persons/objects to previously neutral objects. In this experiment, positive contagion was induced by telling participants in one group that a putter previously belonged to a professional golfer. The effect of positive contagion was examined for perception and performance in a golf putting task. Individuals who believed they were using the professional golfer's putter perceived the size of the golf hole to be larger than golfers without such a belief and also had better performance, sinking more putts. These results provide empirical support for anecdotes, which allege that using objects with positive contagion can improve performance, and further suggest perception can be modulated by positive contagion.

  15. The effect of a carbohydrate-caffeine sports drink on simulated golf performance. (United States)

    Stevenson, Emma J; Hayes, Philip R; Allison, Sarah J


    A round of golf lasts approximately 4 h, during which time homeostasis could be challenged through either hypoglycemia or hypohydration. This might result in impaired motor skill or cognitive performance. Given the high cognitive demand of putting and the potential fatiguing effects from prolonged walking, the combination of a caffeine and carbohydrate drink could be beneficial in offsetting hypoglycemia and hypohydration. This study used a laboratory-simulated round of golf to examine the effect of an isotonic carbohydrate and caffeine sports drink on putting performance during a round of golf. After institutional ethics approval, 20 male golfers (mean +/- standard deviation: age 23 +/- 4 years, stature 176.4 +/- 5.6 cm, mass 72.8 +/- 17.4 kg, handicap 15 +/- 4, daily caffeine consumption 157.3 +/- 47.2 mg) consumed either an isotonic sports drink containing caffeine (6.4 g carbohydrate and 16 mg caffeine per 100 mL) or a no-energy, flavour-matched placebo drink in a double-blind, randomized, counter-balanced crossover design . Drinks were consumed preround (5 body mass (BM)) and at holes 6 and 12 (2.5 BM). Participants therefore consumed 1.6 BM of caffeine and 0.64 BM of carbohydrate throughout the trial. Five and 2 m putting performance were assessed at each hole. Self-rated mood assessments were carried out every third hole. Putting performance over 5 m and 2 m and self-rated scores for alertness and relaxation showed a main effect for drink (p sports drink containing caffeine prior to and during a round of golf improved putting performance and increased feelings of alertness.

  17. Real-time index for predicting successful golf putting motion using multichannel EEG. (United States)

    Muangjaroen, Piyachat; Wongsawat, Yodchanan


    A skill in goal-directed sport performance is an ability involving with many factors of both external and internal concernment. External factors are still developed while internal factors are challenged topic to understand for improving the performance. Internal concernment is explained an effective performance as estimation, solving strategy, planning and decision on the brain. These conjunctions are relevant to somatosensory information, focus attention and fine motor control of cortical activity. Five skilled right-handed golfers were recruited to be subjected of studying the criteria on how to predict golf putt success. Each of their putts was calculated in power spectral analysis by comparing to the pre-movement period. Successful and unsuccessful putt were classified by focusing on the frontal-midline(Fz), parietal-midline(Pz), central midline(Cz), left central(C3) and right central(C4) which supported by few consistency studies that they are related to a primary sensory motor area, focus attention and working memory processing. Results were shown that high alpha power on C4, theta power on Fz, theta power and high alpha power on Pz can be calculated to use as index of predicting golf putt success. Real-time monitoring system with friendly GUI was proposed in this study as promising preliminary study. Expected goal in the future is to apply this real-time golf putting prediction system into a biofeedback system to increase the golf putting's accuracy. However, it still needs more subjects to increase credibility and accuracy of the prediction.

    Full Text Available In an effort to reduce golf turf damage the traditional metal spike golf shoe has been redesigned, but shoe-ground biomechanical evaluations have utilised artificial grass surfaces. Twenty-four golfers wore three different golf shoe traction designs (traditional metal spikes, alternative spikes, and a flat-soled shoe with no additional traction when performing shots with a driver, 3 iron and 7 iron. Ground action forces were measured beneath the feet by two natural grass covered force platforms. The maximum vertical force recorded at the back foot with the 3 iron and 7 iron was 0.82 BW (body weight and at the front foot 1.1 BW approximately in both the metal spike and alternative spike golf shoe designs. When using the driver these maximal vertical values were 0.49 BW at the back foot and 0.84 BW at the front foot. Furthermore, as performance of the backswing and then downswing necessitates a change in movement direction the range of force generated during the complete swing was calculated. In the metal spike shoe the vertical force generated at the back foot with both irons was 0.67 BW and at the front foot 0.96 BW with the 3 iron and 0.92 BW with the 7 iron. The back foot vertical force generated with the driver was 0.33 BW and at the front foot 0.83 BW wearing the metal spike shoe. Results indicated the greater force generation with the irons. When using the driver the more horizontal swing plane associated with the longer club reduced vertical forces at the back and front foot. However, the mediolateral force generated across each foot in the metal and alternative spike shoes when using the driver was greater than when the irons were used. The coefficient of friction was 0. 62 at the back and front foot whichever shoe was worn or club used

  4. Effect of mandibular orthopedic repositioning appliance on kinematic pattern in golf swing. (United States)

    Egret, C; Leroy, D; Loret, A; Chollet, D; Weber, J


    Experience has shown that repositioning the mandible may have an influence on the athletic performance. Many athletes with or without occlusal problems are now using mandibular orthopedic repositioning appliance (MORA) supposedly to optimize their performance. In golf, the players do not have any direct opponent and they have different clubs to reach various distances. Therefore, an automatic swing permits the uncertainty of the movement to be restricted. The aim of this study was to analyze if the use of the MORA could have an effect on the stability of the kinematic pattern in golf swing, connected to the capacity of the golfers to reproduce their swing from kinematic perspective. The measures of kinematic data have been established with the optoelectronic system VICON (Oxford's Metrix, Oxford, UK) with five cameras operating at 50 frames per second. Measurements of the speed of the ball at impact were obtained with a radar (Bridgestone HD.01, Science eye, USA). Six professional (current handicap ranging from 0 to 4) right-handed golfers participated in the study. Six MORA were made and adjusted to fit each player. Each golfer performed five swings without mouthpiece and five with the MORA. The results of this study show that there was no difference related to the MORA on kinematic pattern of the golf swing. Moreover, there were significant differences concerning the ball speed at the impact, among the two test conditions, with or without the appliance (p appliance.

  5. Mental imagery combined with physical practice of approach shots for golf beginners. (United States)

    Brouziyne, M; Molinaro, C


    Recent research on motor skills of golf have pointed to the usefulness of mental imagery. In golf, such training is rarely used as a teaching technique for beginners on the grounds that only top professionals stand to gain from mental imagery. This study tested whether mental imagery combined with physical practice can improve golf performance for the approach shot. 23 volunteer beginners, 8 women and 15 men, M age 23.4 yr. (SD = 3.7), enrolled in the University Physical and Sporting Activities Department, were divided into three groups, using a combination of physical practice of the approach shot plus mental imagery, physical practice only, and a third group engaging in various sporting activities instead of either mental or physical practice of the chip shot. Analysis showed that the beginners' approach shot performance improved most in the group combining physical practice and mental imagery when compared with the group just physically practising the approach shot. It seems mental training can be used effectively to improve performance even with beginners.

    Full Text Available We expose the environmental impact statement (EIS of a future golf course in Toledo city (Spain. This golf course is included in an ambitious scientific-medical research project concerning new therapies through the practice of golf for medullary handicapped persons, in addition with a cultural approach between the three big monotheistic religions that have historically lived together in Toledo. The methodology used to carry out the EIS was very particular and easy to be extrapolated to similar cases, but not to be generalized. It was based in comparing the future project. with the actual intensive irrigation farming of the land, and with the future urban consequences due lo its position next to Toledo city. The comparison between the different environmental impacts of this project and a the actual use of the land, suffering a very intensive irrigation farming, and b the future without the project, was favourable to the golf course, because it was concerned as less aggressive. An appropriate water managing will allow reducing the consumption from the actual 99 l/s authorised for agricultural use, until 54 l/s required for the golf course, improving the environment of this section of the Tajo river: The turf management will be less harmful than the irrigation farming, this one being held nowadays with a high pesticide consumption. Later on, environmental management practice will allow to reduce costs and will help to increase golf-players environmental consciousness. This new golf course will provide the integration o/ this section of Tajo River in the future urban development of Toledo city, creating a green island in its west side, profitable for all city dwellers. This change will be a great improvement, not only for Toledo’s environment, but also for the development of different economical sectors. due to the golf course implantation.Se expone el estudio realizado sobre la incidencia ambiental de un futuro campo de golf en Toledo

  7. Estimation of Center of Mass Trajectory using Wearable Sensors during Golf Swing

    Directory of Open Access Journals (Sweden)

    Bijan Najafi, Jacqueline Lee-Eng, James S. Wrobel, Ruben Goebel


    Full Text Available This study suggests a wearable sensor technology to estimate center of mass (CoM trajectory during a golf swing. Groups of 3, 4, and 18 participants were recruited, respectively, for the purpose of three validation studies. Study 1 examined the accuracy of the system to estimate a 3D body segment angle compared to a camera-based motion analyzer (Vicon®. Study 2 assessed the accuracy of three simplified CoM trajectory models. Finally, Study 3 assessed the accuracy of the proposed CoM model during multiple golf swings. A relatively high agreement was observed between wearable sensors and the reference (Vicon® for angle measurement (r > 0.99, random error 0.93 v. r = 0.52, respectively. On the same note, the proposed two-link model estimated CoM trajectory during golf swing with relatively good accuracy (r > 0.9, A-P random error <1cm (7.7% and <2cm (10.4% for M-L. The proposed system appears to accurately quantify the kinematics of CoM trajectory as a surrogate of dynamic postural control during an athlete’s movement and its portability, makes it feasible to fit the competitive environment without restricting surface type.

  8. Use of industrial byproducts to filter phosphorus and pesticides in golf green drainage water. (United States)

    Agrawal, Sheela G; King, Kevin W; Moore, James F; Levison, Phil; McDonald, Jon


    Golf courses are vulnerable to phosphate (PO) and pesticide loss by infiltration of the sandy, porous grass rooting media used and through subsurface tile drainage. In this study, an effort was made to remove PO, chlorothalonil, mefenoxam, and propiconazole in a golf green's drainage water with a filter blend comprised of industrial byproducts, including granulated blast furnace slag, cement kiln dust, silica sand, coconut shell-activated carbon, and zeolite. To test this filter media, two 6-h storm events were simulated by repeat irrigation of the golf green after PO and pesticide application. Drainage flows ranged from 0.0034 to 0.6433 L s throughout the course of the simulations. A significant decrease in the chlorothalonil load for the experimental run (with filter media) was observed compared with the control (without filter media) ( 80%) near peak flows. In contrast, filter media was not effective in removing PO, mefenoxam, or propiconazole ( > 0.05). Instead, it appears that the filter blend added PO to the effluent above flow rates of 0.037 L s. Overall, flow rate, the amount of filter media used, and contaminant properties may have influenced the filter media's ability to remove contaminants. More research is needed to determine the optimal blend and configuration for the filter media to remove significant amounts of all contaminants investigated.

  9. Effects of a coastal golf complex on water quality, periphyton, and seagrass (United States)

    Lewis, M.A.; Boustany, R.G.; Dantin, D.D.; Quarles, R.L.; Moore, J.C.; Stanley, R.S.


    The objective of this study was to provide baseline information on the effects of a golf course complex on water quality, colonized periphyton, and seagrass meadows in adjacent freshwater, near-coastal, and wetland areas. The chemical and biological impacts of the recreational facility, which uses reclaimed municipal wastewater for irrigation, were limited usually to near-field areas and decreased seaward during the 2-year study. Concentrations of chromium, copper, and organochlorine pesticides were below detection in surface water, whereas mercury, lead, arsenic, and atrazine commonly occurred at all locations. Only mercury and lead exceeded water quality criteria. Concentrations of nutrients and chlorophyll a were greater in fairway ponds and some adjacent coastal areas relative to reference locations and Florida estuaries. Periphyton ash free dry weight and pigment concentrations statistically differed but not between reference and non-reference coastal areas. Biomass of Thalassia testudinum (turtle grass) was approximately 43% less in a meadow located adjacent to the golf complex (P < 0.05). The results of the study suggest that the effects of coastal golf courses on water quality may be primarily localized and limited to peripheral near-coastal areas. However, this preliminary conclusion needs additional supporting data. ?? 2002 Elsevier Science (USA).

  10. Evaluation of a Florida coastal golf complex as a local and watershed source of bioavailable contaminants

    Energy Technology Data Exchange (ETDEWEB)

    Lewis, Michael A.; Quarles, Robert L.; Dantin, Darrin D.; Moore, James C


    Contaminant fate in coastal areas impacted by golf course runoff is not well understood. This report summarizes trace metal, pesticide and PCB residues for colonized periphyton, Ruppia maritima (widgeon grass), Callinectes sapidus Rathbun (blue crabs) and Crassostrea virginica Gemlin (Eastern oyster) collected from areas adjacent to a Florida golf course complex which receive runoff containing reclaimed municipal wastewater. Concentrations of 19 chlorinated pesticides and 18 PCB congeners were usually below detection in the biota. In contrast, 8 trace metals were commonly detected although concentrations were not usually significantly different for biota collected from reference and non-reference coastal areas. Residue concentrations in decreasing order were typically: zinc, arsenic, copper, chromium, lead, nickel, cadmium and mercury. Mean BCF values for the eight trace metals ranged between 160-57 000 (periphyton), 79-11 033 (R. maritima), 87-162 625 (C. virginica) and 12-9800 (C. sapidus). Most trace metal residues in periphyton colonized adjacent to the golf complex, were either similar to or significantly less than those reported for periphyton colonized in nearby coastal areas impacted by urban stormwater runoff and treated municipal and industrial wastewater discharges. Consequently, the recreational complex does not appear to be a major source of bioavailable contaminants locally nor in the immediate watershed based on results for the selected biota.

  12. Environmental Pressures on Tourism Companies: Simulation of Scenarios in Golf Course Operators

    Directory of Open Access Journals (Sweden)

    Alfonso Vargas-Sánchez


    Full Text Available Andalusia (Spain has become one of the world’s leading regions for receiving golf tourists. In recent years there has been a constant increase in the number of golf courses; as a result an institutional context is developing in respect of environment protection that is conditioning the behaviour of companies operating sports/tourism facilities of this type. In the present study we analyse this organizational context from the perspective of the Institutional Theory; we propose possible future scenarios by simulating the evolution of the normative pressures in respect of environmental protection. For this we have applied the statistical technique of Partial Least Squares. The simulation by means of the ceteris paribus criterion has demonstrated for us that an increase of the normative pressures would not substantially modify the results of our original model. We believe that the relatively weak influence of this type of pressure may be because the wide social debate generated in that Spanish region on the sustainability of sports facilities of this type, has propitiated a substantial body of legislation that has conditioned the environmental behaviour of golf courses. Therefore, the best way to obtain legitimacy and social acceptance is still by complying with the law.

    The rising cost of oil coupled with the need to reduce pollution and dependence on foreign suppliers has spurred great interest and activity in developing alternative aviation fuels. Although a variety of fuels have been produced that have similar properties to standard Jet A, detailed studies are required to ascertain the exact impacts of the fuels on engine operation and exhaust composition. In response to this need, NASA acquired and burned a variety of alternative aviation fuel mixtures in the Dryden Flight Research Center DC-8 to assess changes in the aircraft s CFM-56 engine performance and emission parameters relative to operation with standard JP-8. This Alternative Aviation Fuel Experiment, or AAFEX, was conducted at NASA Dryden s Aircraft Operations Facility (DAOF) in Palmdale, California, from January 19 to February 3, 2009 and specifically sought to establish fuel matrix effects on: 1) engine and exhaust gas temperatures and compressor speeds; 2) engine and auxiliary power unit (APU) gas phase and particle emissions and characteristics; and 3) volatile aerosol formation in aging exhaust plumes

  17. Effect of spinal manipulative therapy with stretching compared with stretching alone on full-swing performance of golf players: a randomized pilot trial☆ (United States)

    Costa, Soraya M.V.; Chibana, Yumi E.T.; Giavarotti, Leandro; Compagnoni, Débora S.; Shiono, Adriana H.; Satie, Janice; Bracher, Eduardo S.B.


    Abstract Objective There has been a steady growth of chiropractic treatment using spinal manipulative therapy (SMT) that aims to increase the performance of athletes in various sports. This study evaluates the effect of SMT by chiropractors on the performance of golf players. Methods Golfers of 2 golf clubs in São Paulo, Brazil, participated in this study. They were randomized to 1 of 2 groups: Group I received a stretch program, and group II received a stretch program in addition to SMT. Participants in both groups performed the same standardized stretching program. Spinal manipulative therapy to dysfunctional spinal segments was performed on group II only. All golfers performed 3 full-swing maneuvers. Ball range was considered as the average distance for the 3 shots. Treatment was performed after the initial measurement, and the same maneuvers were performed afterward. Each participant repeated these procedures for a 4-week period. Student t test, Mann-Whitney nonparametric test, and 1-way analysis of variance for repeated measures with significance level of 5% were used to analyze the study. Results Forty-three golfers completed the protocol. Twenty participants were allocated to group I and 23 to group II. Average age, handicap, and initial swing were comparable. No improvement of full-swing performance was observed during the 4 sessions on group I (stretch only). An improvement was observed at the fourth session of group II (P = .005); when comparing the posttreatment, group II had statistical significance at all phases (P = .003). Conclusions Chiropractic SMT in association with muscle stretching may be associated with an improvement of full-swing performance when compared with muscle stretching alone. PMID:19948307

    Full Text Available Independent Ukraine had 50 permanently operating airports in 1991. Nowdays there are currently only 20 operating airports in Ukraine, 2/3 of which require reconstruction and substantial technical re-equipment. Without proper investment, Ukraine is able to lose its status as a transit state, as it is unable to recover its transport infrastructure independently. In connection with this, the international experience of the development of airports, particularly in the Baltic States, Georgia, Norway, Poland, deserves special attention. There are the involvement of foreign companies in the management and reconstruction of airports, especially for the development of tourism and recreation, the coordination of the network of airports with the creation of funds for the development of air routes, the implementation of integrated airport development programs, reducing the base of aviation fees due to the growth of non-aviation revenue, increasing competition in the air transport market through the successful functioning of not only national carriers, but also low-cost carriers. The land-resource potential of different types of transport is the basis of development of the transport system of the country, and also the spatial base. Regulation of land use are conducted depend on the main purpose of the land. A feature of aviation land use transport is the concentration on a small area of land of a significant number of objects and structures of various functional purposes, which provide the work of aviation transport, and require appropriate planning of the territories of airfields and airports. Proceeding from the fact that the airfield belongs to strategic objects, and the airport terminal is considered the object of investment, the separation of land of aviation transport by ownership (state, communal, private and types of use (concession, rent, superficiencies, servitude are rather complex and extremely important task of land management of the respective

    Cramer, K. Elliott; Gavinsky, Bob; Semanskee, Grant


    NASA's Advanced General Aviation Transport Experiments (AGATE) Program has as a goal to reduce the overall cost of producing private aviation aircraft while maintaining the safety of these aircraft. In order to successfully meet this goal, it is necessary to develop nondestructive inspection techniques which will facilitate the production of the materials used in these aircraft and assure the quality necessary to maintain airworthiness. This paper will discuss a particular class of general aviation materials and several nondestructive inspection techniques that have proven effective for making these inspections. Additionally, this paper will discuss the investigation and application of other commercially available quality control techniques applicable to these structures.

  1. Taxation of United States general aviation (United States)

    Sobieralski, Joseph Bernard

    General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994-2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and

  18. Characteristics of successful aviation leaders of Oklahoma (United States)

    Kutz, Mary N. Hill

    Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal

  19. Effects of physical randomness training on virtual and laboratory golf putting performance in novices. (United States)

    Pataky, T C; Lamb, P F


    External randomness exists in all sports but is perhaps most obvious in golf putting where robotic putters sink only 80% of 5 m putts due to unpredictable ball-green dynamics. The purpose of this study was to test whether physical randomness training can improve putting performance in novices. A virtual random-physics golf-putting game was developed based on controlled ball-roll data. Thirty-two subjects were assigned a unique randomness gain (RG) ranging from 0.1 to 2.0-times real-world randomness. Putter face kinematics were measured in 5 m laboratory putts before and after five days of virtual training. Performance was quantified using putt success rate and "miss-adjustment correlation" (MAC), the correlation between left-right miss magnitude and subsequent right-left kinematic adjustments. Results showed no RG-success correlation (r = -0.066, p = 0.719) but mildly stronger correlations with MAC for face angle (r = -0.168, p = 0.358) and clubhead path (r = -0.302, p = 0.093). The strongest RG-MAC correlation was observed during virtual training (r = -0.692, p virtual training, and also that this learning may weakly transfer to real golf putting kinematics. Adaptation to external physical randomness during virtual training may therefore help golfers adapt to external randomness in real-world environments.

  20. Does the transparency of the websites can help in attracting customers? Analysis of the golf courses in Andalusia

    Directory of Open Access Journals (Sweden)

    Marta García-Tascón


    Full Text Available Purpose: The aim of this study is to analyze the degree of transparency of the Web pages of organizations that belong to the world of sports, specifically golf courses in Andalusia. Design/methodology/approach: We performed a descriptive analysis of the conditions of transparency of 92 Web pages of golf clubs registered on the official website of the Royal Golf Federation of Andalusia (RFGA. A questionnaire created/adapted ad hoc is used for this study having as a reference the questionnaire used by Barrio and Martin (2012 that analyze the performance of the 4 conditions of transparency of Web pages. Findings: To reflect a high degree of transparency, they show a higher compliance than 75% in 8 of the 10 variables. The Web page becomes an element to quantify the performance of the field without investing too much in other promotional channels to attract as many customers as possible. Research limitations: In some Web pages, the access to information entailed a significant investment of time because they did not have the characteristic of being intuitive. In some cases was not available all required information. Practical implications: Knowledge of this information allows the director or manager identifies possible areas of improvement to optimize their management, while transparency offered by the golf courses is improved. Social implications: This study highlights the need for teaching the user to evaluate the quality, transparency and being critical with the information found on Web pages. Originality/value: The analysis of transparency allows clubs to be reflective of its golf courses. It becomes the tool that the manager can use to display part of all its virtues and to evaluate the social behavior of their customers, to attract possible clients and perform actions with the stakeholders in the golf industry.

  1. Immediate Effects of Sports Taping Applied on the Lead Knee of Low- and High-Handicapped Golfers During Golf Swing. (United States)

    Kim, Tae-Gyu; Kim, Eun-Kuk; Park, Jong-Chul


    Kim, T-G, Kim, E-K, and Park, J-C. Immediate effects of sports taping applied on the lead knee of low- and high-handicapped golfers during golf swing. J Strength Cond Res 31(4): 981-989, 2017-Elite golf athletes suffer from various musculoskeletal injuries due to repeated golf swings. Repetitive varus moment during golf swing has been suggested as a possible cause of injuries to the lead knee. The aim of this study was to objectively and quantitatively evaluate the immediate effects of sports taping on the lead knee of elite golfers to restrict varus moment. Thirty-one elite golfers were assigned to the low- (LHG, n = 15) or high-handicapped group (HHG, n = 16). Using 3-dimensional motion analysis, the lead knee position on the frontal plane with and without rigid taping (RT), elastic taping (ET), and placebo taping was identified in 4 separate phases by the 5 events of golf swing as follows: the peak of the backswing (E1), parallel to the ground during downswing (E2), ball impact (E3), parallel to the ground during follow-through (E4), and finish (E5). The LHG when using a driver club had decreased movement toward knee varus with RT and ET than that without it from E1 to E2 (p = 0.001). The LHG when using a 5-iron club decreased movement toward knee varus with RT than that without it from E1 to E2 (p = 0.006) and from E2 to E3 (p = 0.019). The HHG when using a driver club had decreased movement toward knee varus with RT from E1 to E2 (p = 0.014). Sports taping may be helpful for elite golfers in terms of reducing varus moment of the lead knee during the downswing and be useful for the development of preventive strategies for golf-related knee injuries.

  14. Mindful Application of Aviation Practices in Healthcare. (United States)

    Powell-Dunford, Nicole; Brennan, Peter A; Peerally, Mohammad Farhad; Kapur, Narinder; Hynes, Jonny M; Hodkinson, Peter D


    Evidence supports the efficacy of incorporating select recognized aviation practices and procedures into healthcare. Incident analysis, debrief, safety brief, and crew resource management (CRM) have all been assessed for implementation within the UK healthcare system, a world leader in aviation-based patient safety initiatives. Mindful application, in which aviation practices are specifically tailored to the unique healthcare setting, show promise in terms of acceptance and long-term sustainment. In order to establish British healthcare applications of aviation practices, a PubMed search of UK authored manuscripts published between 2005-2016 was undertaken using search terms 'aviation,' 'healthcare,' 'checklist,' and 'CRM.' A convenience sample of UK-authored aviation medical conference presentations and UK-authored patient safety manuscripts were also reviewed. A total of 11 of 94 papers with UK academic affiliations published between 2005-2016 and relevant to aviation modeled healthcare delivery were found. The debrief process, incident analysis, and CRM are the primary practices incorporated into UK healthcare, with success dependent on cultural acceptance and mindful application. CRM training has gained significant acceptance in UK healthcare environments. Aviation modeled incident analysis, debrief, safety brief, and CRM training are increasingly undertaken within the UK healthcare system. Nuanced application, in which the unique aspects of the healthcare setting are addressed as part of a comprehensive safety approach, shows promise for long-term success. The patient safety brief and aviation modeled incident analysis are in earlier phases of implementation, and warrant further analysis.Powell-Dunford N, Brennan PA, Peerally MF, Kapur N, Hynes JM, Hodkinson PD.

  15. Object-Oriented Bayesian Networks (OOBN) for Aviation Accident Modeling and Technology Portfolio Impact Assessment (United States)

    Shih, Ann T.; Ancel, Ersin; Jones, Sharon M.


    The concern for reducing aviation safety risk is rising as the National Airspace System in the United States transforms to the Next Generation Air Transportation System (NextGen). The NASA Aviation Safety Program is committed to developing an effective aviation safety technology portfolio to meet the challenges of this transformation and to mitigate relevant safety risks. The paper focuses on the reasoning of selecting Object-Oriented Bayesian Networks (OOBN) as the technique and commercial software for the accident modeling and portfolio assessment. To illustrate the benefits of OOBN in a large and complex aviation accident model, the in-flight Loss-of-Control Accident Framework (LOCAF) constructed as an influence diagram is presented. An OOBN approach not only simplifies construction and maintenance of complex causal networks for the modelers, but also offers a well-organized hierarchical network that is easier for decision makers to exploit the model examining the effectiveness of risk mitigation strategies through technology insertions.

  16. Applications of Doppler radar to aviation operations - JAWS experiences (United States)

    Mccarthy, J.; Wilson, J. W.


    The field phase of the Joint Airport Weather Studies (JAWS) Project was conducted in the vicinity of Denver's Stapleton International Airport from 15 May to 13 August 1982. The primary collection systems were three Doppler radars, a 27-station, closely spaced (4 km) network of surface stations, and five research aircraft. The program was specifically planned to observe wind shear phenomena with high time and space resolution that would be dangerous to aircraft operations. The program was successful in observing a large number of such events. Preliminary conclusions are presented on the effectiveness of several wind shear detection systems to warn of wind shear events critical to aviation safety.

  17. Eco-efficiency in aviation

    Directory of Open Access Journals (Sweden)

    Volker Grewe


    Full Text Available Air traffic guarantees mobility and serves the needs of society to travel over long distances in a decent time. But aviation also contributes to climate change. Here, we present various mitigation options, based on technological and operational measures and present a framework to compare the different mitigation options by taking into account aspects, such as changes in operational costs, climate impact reduction, eco-efficiency, possible starting point of the mitigation option and the investment costs. We show that it is not possible to directly rank these options because of the different requirements and framework conditions. Instead, we introduce two different presentations that take into account these different aspects and serve as a framework for intercomparison.

  18. Development of a golf-specific load monitoring tool: Content validity and feasibility. (United States)

    Williams, Scott B; Gastin, Paul B; Saw, Anna E; Robertson, Sam


    Athletes often record details of their training and competitions, supported by information such as environmental conditions, travel, as well as how they felt. However, it is not known how prevalent these practices are in golfers, or how valuable this process is perceived. The purpose of this study was to develop a golf-specific load monitoring tool (GLMT), and establish the content validity and feasibility of this tool amongst high-level golfers. In the first phase of development, 21 experts were surveyed to determine the suitability of items for inclusion in the GLMT. Of the 36 items, 21 received >78% agreement, a requirement to establish content validity and for inclusion in the GLMT. Total duration was the preferred metric for golf-specific activities, whilst rating of perceived exertion (RPE) was preferred for measuring physical training. In the second phase, feasibility of the tool was assessed by surveying 13 high-level male golfers following 28-days of daily GLMT use. All items included in the GLMT were deemed feasible to record, with all players participating in the feasibility study providing high to very high ratings. Golfers responded that they would consider using a load monitoring tool of this nature long term, provided it can be completed in less than five minutes per day.

  19. Electromyographic analysis of lower limb muscles during the golf swing performed with three different clubs. (United States)

    Marta, Sérgio; Silva, Luís; Vaz, João Rocha; Castro, Maria António; Reinaldo, Gustavo; Pezarat-Correia, Pedro


    The aim of this study was to describe and compare the EMG patterns of select lower limb muscles throughout the golf swing, performed with three different clubs, in non-elite middle-aged players. Fourteen golfers performed eight swings each using, in random order, a pitching wedge, 7-iron and 4-iron. Surface electromyography (EMG) was recorded bilaterally from lower limb muscles: tibialis anterior, peroneus longus, gastrocnemius medialis, gastrocnemius lateralis, biceps femoris, semitendinosus, gluteus maximus, vastus medialis, rectus femoris and vastus lateralis. Three-dimensional high-speed video analysis was used to determine the golf swing phases. Results showed that, in average handicap golfers, the highest muscle activation levels occurred during the Forward Swing Phase, with the right semitendinosus and the right biceps femoris muscles producing the highest mean activation levels relative to maximal electromyography (70-76% and 68-73% EMG(MAX), respectively). Significant differences between the pitching wedge and the 4-iron club were found in the activation level of the left semitendinosus, right tibialis anterior, right peroneus longus, right vastus medialis, right rectus femuris and right gastrocnemius muscles. The lower limb muscles showed, in most cases and phases, higher mean values of activation on electromyography when golfers performed shots with a 4-iron club.

  20. Analysis of Pelvis-Thorax Coordination Patterns of Professional and Amateur Golfers during Golf Swing. (United States)

    Sim, Taeyong; Yoo, Hakje; Choi, Ahnryul; Lee, Ki Young; Choi, Mun-Taek; Lee, Soeun; Mun, Joung Hwan


    The aim of this research was to quantify the coordination pattern between thorax and pelvis during a golf swing. The coordination patterns were calculated using vector coding technique, which had been applied to quantify the coordination changes in coupling angle (γ) between two different segments. For this, fifteen professional and fifteen amateur golfers who had no significant history of musculoskeletal injuries. There was no significant difference in coordination patterns between the two groups for rotation motion during backswing (p = 0.333). On the other hand, during the downswing phase, there were significant differences between professional and amateur groups in all motions (flexion/extension: professional [γ] = 187.8°, amateur [γ] = 167.4°; side bending: professional [γ] = 288.4°, amateur [γ] = 245.7°; rotation: professional [γ] = 232.0°, amateur [γ] = 229.5°). These results are expected to be a discriminating measure to assess complex coordination of golfers' trunk movements and preliminary study for interesting comparison by golf skilled levels.

  1. Title ultrasound features of ovarian melanoma metastases: The "Golf ball" aspect. (United States)

    Vimercati, Antonella; Suma, Cosimina; Cicinelli, Ettore; Resta, Leonardo; Cormio, Gennaro


    Melanoma is an malignant tumor with an unpredictable profile of spread and variable periods of remissions. Both ovarian involvement of malignant melanoma and primary ovarian melanoma are extremely rare conditions with few cases reported in the literature. They always represent a diagnostic challenge as they mimic various ovarian entities from primary ovarian malignancy to benign tumors. Ovarian metastasis often present with images similar to the primary tumors, and there is no typical finding that differentiate them, apart from the multilocular tendency which would favor a primary process. We here report an extremely rare case of ovarian melanoma metastasis with detailed ultrasound examination, never specifically described in literature and whit the "Golf Ball" aspect. This metastatic tumor seems to be bilateral, with mean diameter (<10cm), main solid appearance, and rich vascularization, so more comparable to stomach-breast metastases. Moreover atypical multiple small cysts responsible of ultrasound "golf ball" aspect correspond to the histological diagnosis of follicular cysts surrounded by metastatic cancer while partial hyperechoic solid component could be related to the different histological pattern. These sonographic features may be useful in the difficult differential diagnosis between ovarian cancer primitive and ovarian melanoma metastases especially in cases with unclear patient history.

    Full Text Available Skilled performers exhibit more efficient gaze patterns than less-skilled counterparts do and they look more frequently at task-relevant regions than at superfluous ones. We examine whether we may guide novices' gaze towards relevant regions during action observation in order to facilitate their learning of a complex motor skill. In a Pre-test-Post-test examination of changes in their execution of the full golf swing, 21 novices viewed one of three videos at intervention: i a skilled golfer performing 10 swings (Free Viewing, FV; ii the same video with transient colour cues superimposed to highlight key features of the setup (Visual Guidance; VG; iii or a History of Golf video (Control. Participants in the visual guidance group spent significantly more time looking at cued areas than did the other two groups, a phenomenon that persisted after the cues had been removed. Moreover, the visual guidance group improved their swing execution at Post-test and on a Retention test one week later. Our results suggest that visual guidance to cued areas during observational learning of complex motor skills may accelerate acquisition of the skill.

  4. A parametric study of golf car and personal transport vehicle braking stability and their deficiencies. (United States)

    Seluga, Kristopher J; Baker, Lowell L; Ojalvo, Irving U


    This paper describes research and parametric analyses of braking effectiveness and directional stability for golf cars, personal transport vehicles (PTVs) and low speed vehicles (LSVs). It is shown that current designs, which employ brakes on only the rear wheels, can lead to rollovers if the brakes are applied while traveling downhill. After summarizing the current state of existing safety standards and brake system designs, both of which appear deficient from a safety perspective, a previously developed dynamic simulation model is used to identify which parameters have the greatest influence on the vehicles' yaw stability. The simulation results are then used to parametrically quantify which combination of these factors can lead to yaw induced rollover during hard braking. Vehicle velocity, steering input, path slope and tire friction are all identified as important parameters in determining braking stability, the effects of which on rollover propensity are presented graphically. The results further show that when vehicles are equipped with front brakes or four-wheel brakes, the probability of a yaw induced rollover is almost entirely eliminated. Furthermore, the parametric charts provided may be used as an aid in developing guidelines for golf car and PTV path design if rear brake vehicles are used.

  5. Use of piezoelectric dampers for improving the feel of golf clubs (United States)

    Bianchini, Emanuele; Spangler, Ronald L., Jr.; Pandell, Tracy


    Several sports are based upon a tool (club, bat, stick) striking an object (ball, puck) across a field of play. Anytime two structures collide, vibration is created by the impact of the two. The impact of the objects excites the structural modes of the tool, creating a vibration that can be felt by the player, especially if the hit is not at a `sweet spot'. Vibration adversely affects both feel and performance. This paper explains how piezoelectric dampers were developed to reduce vibration and improve the feel of ball-impact sporting goods such as golf clubs. The paper describes how the dynamic characteristics of a golf club were calculated, at first in the free-free condition, and then during its operation conditions (the swing of the club, and the impact with the ball). The dynamic characteristics were used to develop a damper that addressed a specific, or multiple, modes of interest. The damper development and testing are detailed in this paper. Both objective laboratory tests and subjective player tests were performed to evaluate the effectiveness of the piezoelectric dampers. The results of the tests, along with published medical data on the sensitivity of the human body, were used to draw a correlation between human feel and vibration reduction.

  6. Life history and spatial distribution of Oriental beetle (Coleoptera: Scarabaeidae) in golf courses in Korea. (United States)

    Choo, Ho Yul; Lee, Dong Woon; Park, Ji Woong; Kaya, Harry K; Smitley, David R; Lee, Sang Myeong; Choo, Young Moo


    Larval and adult activity of the oriental beetle Exomala orientalis (Waterhouse), a pest of turfgrass in Korea, was investigated at four golf clubs in Pusan, Korea, from 1995 to 1999. Adult emergence was first observed on the greens in late May with peak activity occurring 2 wk later. During the day, E. orientalis adults were most active between 1800 and 2200 hours. First instars were found mostly in early July, second instars mostly in late July, and third instars from August to April. The density of larvae in fixed plots decreased steadily from the time of egg laying to pupation: 667/m3 on 26 July, 267/m3 on 29 August, and 122/m3 on 2 October 1997. All the observed E. orientalis completed one generation per year. Adult females were observed feeding on flowers of a late-blooming variety of Japanese chestnut (Castanea crenata Sieb & Zucc). E. orientalis larval densities were higher in greens with Japanese chestnut nearby, and where magpie, Pica pica sericea (Gould), feeding was observed. More E. orientalis adults emerged from the right, left, and back of greens than from the front or middle. The intensity of emergence was inversely proportional to the amount of golfer traffic on various parts of the green. Counting emergence holes may be a way that golf course superintendents can predict which greens and tees are most likely to be damaged from E. orientalis larvae without destructive sampling.

  7. Degradation and sorption of the fungicide tebuconazole in soils from golf greens. (United States)

    Badawi, Nora; Rosenbom, Annette E; Jensen, Anne M D; Sørensen, Sebastian R


    The fungicide tebuconazole (TBZ) is used to repress fungal growth in golf greens and ensure their playability. This study determined the degradation and sorption of TBZ applied as an analytical grade compound, a commercial fungicide formulation or in combination with a surfactant product in thatch and soils below two types of greens (USGA and push-up greens) in 12-cm vertical profiles covered by three different types of turf grass. Only minor TBZ degradation was observed and it was most pronounced in treatments with the commercial fungicide product or in combination with the surfactant compared to the analytical grade compound alone. A tendency for higher TBZ sorption when applied as the formulated product and lowest sorption when applied as a formulated product in combination with the surfactant was observed, with this effect being most distinct on USGA greens. No correlation between occurrence of degradation and soil depth, green type or grass type was observed. Sorption seemed to be the main process governing the leaching risk of TBZ from the greens and a positive correlation to the organic matter content was shown. In light of these findings, organic matter content should be taken into consideration during the construction of golf courses, especially when following USGA guidelines.

  8. Aviation Research and the Internet (United States)

    Scott, Antoinette M.


    The Internet is a network of networks. It was originally funded by the Defense Advanced Research Projects Agency or DOD/DARPA and evolved in part from the connection of supercomputer sites across the United States. The National Science Foundation (NSF) made the most of their supercomputers by connecting the sites to each other. This made the supercomputers more efficient and now allows scientists, engineers and researchers to access the supercomputers from their own labs and offices. The high speed networks that connect the NSF supercomputers form the backbone of the Internet. The World Wide Web (WWW) is a menu system. It gathers Internet resources from all over the world into a series of screens that appear on your computer. The WWW is also a distributed. The distributed system stores data information on many computers (servers). These servers can go out and get data when you ask for it. Hypermedia is the base of the WWW. One can 'click' on a section and visit other hypermedia (pages). Our approach to demonstrating the importance of aviation research through the Internet began with learning how to put pages on the Internet (on-line) ourselves. We were assigned two aviation companies; Vision Micro Systems Inc. and Innovative Aerodynamic Technologies (IAT). We developed home pages for these SBIR companies. The equipment used to create the pages were the UNIX and Macintosh machines. HTML Supertext software was used to write the pages and the Sharp JX600S scanner to scan the images. As a result, with the use of the UNIX, Macintosh, Sun, PC, and AXIL machines, we were able to present our home pages to over 800,000 visitors.

    Background and Purpose: Golf is a popular sport played by hundreds of thousands of individuals of all ages and of varying skill levels. An orthopedic or sports-related injury and/or surgery may limit an individual's sport participation, require him/her to complete a course of rehabilitation, and initiate (or resume) a sport-specific training program. Unlike the availability of evidence to guide postsurgical rehabilitation and sport-specific training of athletes from sports other than golf, there have only been two reports describing outcomes after surgery and for golfers. The purpose of this case report is to present a post-rehabilitation return to sport-training program for a recreational golfer 11-months after a rotator cuff repair. Case Description: The subject, a 67-year old female, injured her right shoulder requiring a rotator cuff repair 11-months prior to her participation in a golf fitness training program. The subject participated in six training sessions over seven week period consisting of general strengthening exercises (including exercises for the rotator cuff), exercises for the core, plyometrics, and power exercises. Outcomes: The subject made improvements in power and muscular endurance of the core. She was able to resume golf at the completion of the training program. Discussion: The subject was able to make functional improvements and return to golf after participation in a comprehensive strength program. Additional studies are necessary to improve program design for golfers who wish to return to sport after shoulder surgery. PMID:22163096

  12. Assessing the impact of aviation on climate

    Directory of Open Access Journals (Sweden)

    Karen Marais


    Full Text Available We present an assessment of the marginal climate impacts of new aviation activities. We use impulse response functions derived from carbon-cycle and atmospheric models to estimate changes in surface temperature for various aviation impacts (CO2, NOx on methane, NOx on ozone, sulfates, soot, and contrails/induced cirrus. We use different damage functions and discount rates to explore health, welfare and ecological costs for a range of assumptions and scenarios. Since uncertainty is high regarding many aviation effects, we explicitly capture some uncertainty by representing several model parameters as probabilistic distributions. The uncertainties are then propagated using Monte Carlo analysis to derive estimates for the impact of these uncertainties on the marginal future climate impacts. Our goal is to provide a framework that will communicate the potential impacts of aviation on climate change under different scenarios and assumptions, and that will allow decision-makers to compare these potential impacts to other aviation environmental impacts. We present results to describe the influence of parametric uncertainties, scenarios, and assumptions for valuation on the expected marginal future costs of aviation impacts. Estimates of the change in global average surface temperature due to aviation are most sensitive to changes in climate sensitivity, the radiative forcing attributed to short-lived effects (in particular those related to contrails and aviation-induced cirrus, and the choice of emissions scenario. Estimates of marginal future costs of aviation are most sensitive to assumptions regarding the discount rate, followed by assumptions regarding climate sensitivity, and the choice of emissions scenario.

  14. The identification of benefit needs of golf players in the U.S.: Implicationsand strategy considerations for sport management professionals

    Directory of Open Access Journals (Sweden)



    Full Text Available The golf industry has expanded over the past 50 years throughout the world, particularly in America. The number of golfers in the United States has increased seven-fold since 1950, as the game was transformed from an expensive diversion of the rich to a mass-market pastime. A number of recent studies have shown that demographic variables such as age, gender, occupation, income, and race are –in general– poor predictors of golfers’ consumer behaviour and, consequently, less than optimum bases for segmentation strategies. Because of those problems associated with demographic segmentation, benefit segmentation has become a favourite tool of marketers; to satisfy target consumers’ needs, benefit needs and product attributes are the most popular variables for segmenting the target market. The main strength of benefit segmentation lies in the causal relationship to perceived future behaviour. The purpose of this study was to identify the benefit needs of golfers who frequent public golf courses. Implications for public golf course owners or managers are then discussed with strategy considerations about golf marketing for a variety of benefit segments.

    Full Text Available There are several reasons for the English language to become lingua franca of aviation including some historical turning points for the world aviation and some specific linguistic features of the language itself. This paper aims to firstly present a short, yet interesting history of implementation of English as standardized language for aviation. It will provide introductory historical background, establishment of arguments necessary for standardization and leading to the implementation of the Language Proficiency Requirements (LPRs within the International Civil Aviation Organization (ICAO. It will then provide an overview of the ICAO’s actions to support its members states in implementation of the English language standards for aviation and try to evaluate the effects based on the powers granted to the Organization. Such evaluation will be presented in the comparative perspective with the powers and instruments used within the European Union to achieve the same goal - standardization of the aviation English.

    Full Text Available In the article we represent the basic principles of municipal air transport within the metropolis. The main tasks of creating municipal transport are defined to further develop of aviation technologies for municipal economy and life support of the city and its air-transport system. In order to further development of aviation technology in the interests of the urban economy and life of the city, its air transportation system is necessary to decide three main objectives: development of aviation equipment and saturation of City Aviation park by light helicopters which will ensure solving of special tasks for the benefit of urban services, commercial transportation and air operations; development of urban aviation infrastructure, including heliports and helipads; the organization of safe use of the airspace over the city. The use of technology in aviation can be done while ensuring sanitary and environmental standards of environmental protection.

  1. The effect of leisure activity golf practice on motor imagery: an fMRI study in middle adulthood

    Directory of Open Access Journals (Sweden)

    Ladina eBezzola


    Full Text Available Much is known about practice-induced plasticity of the motor system. But it is not clear whether the activity in the motor network induced by mental motor imagery is influenced by actually practicing the imagined motor tasks.In a longitudinal study design with two measurement time-points, functional magnetic resonance imaging (fMRI was used to explore dynamic changes in the brain in response to training of highly complex movements by participants of 40 to 60 years of age. The investigated motor learning task entailed golf training practiced by novices as leisure activity. Additionally, data from an age and sex-matched control group without golf training was collected.Results show increased hemodynamic responses during mental rehearsal of a golf swing in non-primary cortical motor areas, sub-cortical motor areas, and parietal regions of the novice golfers and the control subjects. This result complements previous mental imagery research that shows involvement of motor areas during mental rehearsal of a complex movement, especially in subjects with low skill level. More importantly, changes were only found between the two measurement time-points in the golf novice group with a decrease in hemodynamic responses in non-primary motor areas after the 40 hours of golf practice. Thus, the results indicate that a complex physical leisure activity induces functional neuroplasticity in the seldom studied population of middle-aged adults, and that this effect is evident during mental rehearsal of the practiced task. This finding supports the idea that (a a skill improvement is associated with a modified activation pattern in the associated neuronal network that can be identified during mental rehearsal of the practiced task, and that (b a strict training protocol is not necessary to induce functional neuroplasticity.

  2. Kinematic evaluation of movement smoothness in golf: relationship between the normalized jerk cost of body joints and the clubhead. (United States)

    Choi, Ahnryul; Joo, Su-Bin; Oh, Euichaul; Mun, Joung Hwan


    When the human body is introduced to a new motion or movement, it learns the placement of different body parts, sequential muscle control, and coordination between muscles to achieve necessary positions, and it hones this new skill over time and repetition. Previous studies have demonstrated definite differences in the smoothness of body movements with different levels of training, i.e., amateurs compared with professionals. Therefore, we tested the hypothesis that skilled golfers swing a driver with a smoother motion than do unskilled golfers. In addition, the relationship between the smoothness of body joints and that of the clubhead was evaluated to provide further insight into the mechanism of smooth golf swing. Two subject groups (skilled and unskilled) participated in the experiment. The skilled group comprised 20 male professional golfers registered with the Korea Professional Golf Association, and the unskilled group comprised 19 amateur golfers who enjoy golf as a hobby. Six infrared cameras (VICON460 system) were used to record the 3D trajectories of markers attached to the clubhead and body segments, and the resulting data was evaluated with kinematic analysis. A physical quantity called jerk was calculated to investigate differences in smoothness during downswing between the two study groups. The hypothesis that skilled golfers swing a driver with a smoother motion than do unskilled golfers was supported. The normalized jerk of the clubhead of skilled golfers was lower than that of unskilled golfers in the anterior/posterior, medial/lateral, and proximal/distal directions. Most human joints, especially in the lower body, had statistically significant lower normalized jerk values in the skilled group. In addition, the normalized jerk of the skilled group's lower body joints had a distinct positive correlation with the normalized jerk of the clubhead with r = 0.657 (p joints than that of the upper body joints.

  4. The Aviation System Analysis Capability Air Carrier Cost-Benefit Model (United States)

    Gaier, Eric M.; Edlich, Alexander; Santmire, Tara S.; Wingrove, Earl R.., III


    To meet its objective of assisting the U.S. aviation industry with the technological challenges of the future, NASA must identify research areas that have the greatest potential for improving the operation of the air transportation system. Therefore, NASA is developing the ability to evaluate the potential impact of various advanced technologies. By thoroughly understanding the economic impact of advanced aviation technologies and by evaluating how the new technologies will be used in the integrated aviation system, NASA aims to balance its aeronautical research program and help speed the introduction of high-leverage technologies. To meet these objectives, NASA is building the Aviation System Analysis Capability (ASAC). NASA envisions ASAC primarily as a process for understanding and evaluating the impact of advanced aviation technologies on the U.S. economy. ASAC consists of a diverse collection of models and databases used by analysts and other individuals from the public and private sectors brought together to work on issues of common interest to organizations in the aviation community. ASAC also will be a resource available to the aviation community to analyze; inform; and assist scientists, engineers, analysts, and program managers in their daily work. The ASAC differs from previous NASA modeling efforts in that the economic behavior of buyers and sellers in the air transportation and aviation industries is central to its conception. Commercial air carriers, in particular, are an important stakeholder in this community. Therefore, to fully evaluate the implications of advanced aviation technologies, ASAC requires a flexible financial analysis tool that credibly links the technology of flight with the financial performance of commercial air carriers. By linking technical and financial information, NASA ensures that its technology programs will continue to benefit the user community. In addition, the analysis tool must be capable of being incorporated into the

    Full Text Available The article elaborates the proposals to improve the systems for monitoring performance of the equipment at the enterprises of aviation instrument. The relevance of the study due to the fact that the aviation instrument-making industry of the Russian Federation can play a role as a key factor in enhancing the competitiveness of the national economy. Currently, the global aviation market is fairly saturated, it competition is not between individual companies and between the aviation powers. The role of an efficient industrial production is largely dependent on the amount, structure, technical condition and the level of utilization of fixed assets. Specificity of high-tech high-tech production presupposes the existence of a specific fleet of expensive and unique equipment; a high degree of novelty products, single or small-scale type of production that determines the high cost of production of a unit of production; high demands on the staff . The paper noted that the production capacity is an essential tool for production planning process, which allows to determine the optimal work shifts Park main technological equipment and production program to justify the enterprises of sphere of aviation instrument. On the basis of the modification of OEE method, a stochastic model is proposed, which allows to display the efficiency of the productive capacity of the high-tech enterprises of sphere of aviation instrument in the form of multi-dimensional size and much more accurately identify the relationship between its elements.

    Full Text Available The aim was to describe development of a process-oriented instrument designed to assess the golf swing and putt stroke, and to assess the instrument’s discriminative validity in terms of age and reliability (intra-rater and re-test. A Delphi consultation (with golf industry professionals and researchers in movement skill assessment was used to develop an assessment for each skill based on existing skill assessment protocols. Each skill had six components to be marked as present/absent. Individual scores were based on the number of performance components successfully demonstrated over two trials for each skill (potential score range 0 to 24. Children (n = 43 aged 6-10 years (M = 7.8 years, SD = 1.3 were assessed in both skills live in the field by one rater at Time 1(T1. A subset of children (n = 28 had consent for assessments to be videoed. Six weeks later 19 children were reassessed, five days apart (T2, T3. An ANOVA assessed discriminative validity i.e. whether skill competence at T1 differed by age (6 years, 7/8 years and 9/10 years. Intraclass correlations (ICC assessed intra-rater reliability between the live and video assessment at T1 and test-retest reliability (between T2 and T3. Paired t-tests assessed any systematic differences between live and video assessments (T1 and between T2 and T3. Older children were more skilled (F (2, 40 = 11.18, p < 0.001. The live assessment reflected the video assessment (ICC = 0.79, 95% CI 0.59, 0.90 and scores did not differ between live and video assessments. Test retest reliability was acceptable (ICC = 0.60, 95% CI 0.23, 0.82, although the mean score was slightly higher at retest. This instrument could be used reliably by golf coaches and physical education teachers as part of systematic early player assessment and feedback.

  4. Aviation Safety Concerns for the Future (United States)

    Smith, Brian E.; Roelen, Alfred L. C.; den Hertog, Rudi


    The Future Aviation Safety Team (FAST) is a multidisciplinary international group of aviation professionals that was established to identify possible future aviation safety hazards. The principle was adopted that future hazards are undesirable consequences of changes, and a primary activity of FAST became identification and prioritization of possible future changes affecting aviation. Since 2004, FAST has been maintaining a catalogue of "Areas of Change" (AoC) that could potentially influence aviation safety. The horizon for such changes is between 5 to 20 years. In this context, changes must be understood as broadly as possible. An AoC is a description of the change, not an identification of the hazards that result from the change. An ex-post analysis of the AoCs identified in 2004 demonstrates that changes catalogued many years previous were directly implicated in the majority of fatal aviation accidents over the past ten years. This paper presents an overview of the current content of the AoC catalogue and a subsequent discussion of aviation safety concerns related to these possible changes. Interactions among these future changes may weaken critical functions that must be maintained to ensure safe operations. Safety assessments that do not appreciate or reflect the consequences of significant interaction complexity will not be fully informative and can lead to inappropriate trade-offs and increases in other risks. The FAST strongly encourages a system-wide approach to safety risk assessment across the global aviation system, not just within the domain for which future technologies or operational concepts are being considered. The FAST advocates the use of the "Areas of Change" concept, considering that several possible future phenomena may interact with a technology or operational concept under study producing unanticipated hazards.

  10. Initial cognitive performance predicts longitudinal aviator performance. (United States)

    Yesavage, Jerome A; Jo, Booil; Adamson, Maheen M; Kennedy, Quinn; Noda, Art; Hernandez, Beatriz; Zeitzer, Jamie M; Friedman, Leah F; Fairchild, Kaci; Scanlon, Blake K; Murphy, Greer M; Taylor, Joy L


    The goal of the study was to improve prediction of longitudinal flight simulator performance by studying cognitive factors that may moderate the influence of chronological age. We examined age-related change in aviation performance in aircraft pilots in relation to baseline cognitive ability measures and aviation expertise. Participants were aircraft pilots (N = 276) aged 40-77.9. Flight simulator performance and cognition were tested yearly; there were an average of 4.3 (± 2.7; range 1-13) data points per participant. Each participant was classified into one of the three levels of aviation expertise based on Federal Aviation Administration pilot proficiency ratings: least, moderate, or high expertise. Addition of measures of cognitive processing speed and executive function to a model of age-related change in aviation performance significantly improved the model. Processing speed and executive function performance interacted such that the slowest rate of decline in flight simulator performance was found in aviators with the highest scores on tests of these abilities. Expertise was beneficial to pilots across the age range studied; however, expertise did not show evidence of reducing the effect of age. These data suggest that longitudinal performance on an important real-world activity can be predicted by initial assessment of relevant cognitive abilities.

  11. General Aviation Pilots Over 70 Years Old. (United States)

    Vuorio, Alpo; Asmayawati, Saryani; Budowle, Bruce; Griffiths, Robin; Strandberg, Timo; Kuoppala, Jaana; Sajantila, Antti


    Currently it is not unusual for general aviation pilots in the United States to continue to fly beyond the age of 70, even into their 80s and 90s. Pilots have regular examinations according to protocols which do not specify special or additional requirements for pilots over 70 yr of age. Additionally, the third class medical reforms passed by the U.S. Senate on 15 July 2016 could potentially result in even less stringent medical certification requirements for general aviation pilots. Accident rates, medical parameters, autopsy findings, and toxicological findings from the U.S. National Transportation Safety Board (NTSB) general aviation (GA) accident database were analyzed to assess potential risk factors with accident outcomes. During 2003-2012, there were 114 (113 men, 1 woman) general aviation fatal accidents involving pilots ages 70 to 92 yr. A combination of 3 or more drugs were found in 13 (13%) of deceased pilots. The most frequent drugs were first generation antihistamines and antidepressants represented the next highest proportion of possible performance-affecting medications. This study indicates that there are critical medical factors that may contribute to fatal accidents among elderly pilots. Polypharmacy use should be taken into consideration, especially during periodic health examinations and fatal aviation investigations involving elderly pilots.Vuorio A, Asmayawati S, Budowle B, Griffiths R, Strandberg T, Kuoppala J, Sajantila A.

  13. Emotions and golf performance: An IZOF-based applied sport psychology case study. (United States)

    Cohen, Alexander B; Tenenbaum, Gershon; English, R William


    A multiple case study investigation is reported in which emotions and performance were assessed within the probabilistic individual zone of optimal functioning (IZOF) model (Kamata, Tenenbaum,& Hanin, 2002) to develop idiosyncratic emotion-performance profiles. These profiles were incorporated into a psychological skills training (PST) intervention, with a focus on three emotional dimensions, that is, arousal, pleasantness, and functionality, and several psychological strategies employed during practice and competition. Two female varsity golfers at a major Division I university in the Southeast participated in the case study during the Spring 2002 season. The PST intervention resulted in enhanced emotional self-regulation skills and improved golf performance. Directions for future research into the IZOF model and implications for practical application of the model are discussed.

  14. Positive psychology interventions in golf: Mindfulness versus positive self-talk

    Directory of Open Access Journals (Sweden)


    Results: There was a significant multivariate effect of Time on putting test scores, F(1, 21 = 13.9, p = .001, Ƞ2 = .399. Specifically, a mean increase of 1.4 out of 10 putts over the 4-week intervention period was found, but no univariate effect of Time on distance (cm from the hole for putts missed. There was no Group or Time by Group interaction effect for either putting test variable. Furthermore, groups did not differ at baseline or post-intervention on reported handicap, KIMS, technique adherence, or rounds of golf played. Conclusions: These preliminary findings fail to support previously reported findings that mindfulness or positive self-talk have short-term effects on putting accuracy. To maximise access, the current study used a self-guided intervention, which may have accounted for the lack of improvement that may occur with one-on-one coaching.

  15. Distinguishing Event Spectator Spending Profiles: Projected Impacts of the 2009 U.S. Open Golf Championship

    Directory of Open Access Journals (Sweden)

    Amy K.S. Scott


    Full Text Available Spectators at mega-sport events are an aggregation of market segments with distinct consumer behaviours. Relatively few economic impact studies have distinguished spectator market segments or the event tourists crowding out other visitors, resulting in inaccurate results. Despite a plethora of prior studies, there remains a need for a refined and agile model to predict a sporting event’s economic impact. The purpose of this study is to describe the ex ante model, ACE: Assessing Consumers of Events, developed to estimate spending impacts by spectators. ACE is then applied to the 2009 U.S. Women’s Open Golf Championship to illustrate its data requirements and results. U.S. Open spectators are projected to spend $7.5 million in the host economy and induce a slight crowding out effect. Future applications of the ACE model are discussed.

  1. Changes in task self-efficacy and emotion across competitive performances in golf. (United States)

    Boardley, Ian D; Jackson, Ben; Simmons, Alexander


    This research aimed to investigate (a) the effect of golfers' perceptions of coach motivation efficacy on golfers' precompetition task self-efficacy, (b) the effect of performance on pre-to-postround changes in self-efficacy, (c) the effect of pre-to-postround changes in self-efficacy on pre-to-postround changes in affect and emotion, and (d) whether any effects of performance on pre-to-postcompetition changes in affect and emotion were mediated by pre-to-postcompetition changes in self-efficacy. In Study 1, a scale measuring golf self-efficacy was developed and validated using data from 197 golfers. In Study 2, 200 golfers completed this measure alongside measures of coach motivation efficacy, and positive and negative affect before a golf competition; all measures (except coach motivation efficacy) were again completed following the competition. Structural equation modeling showed that coach motivation efficacy positively predicted precompetition self-efficacy, performance positively predicted pre-to-postcompetition changes in self-efficacy, which had positive and negative effects, respectively, on pre-to-postcompetition changes in positive and negative affect; mediation analyses demonstrated that pre-to-postcompetition changes in self-efficacy mediated effects of performance on pre-to-postcompetition changes in positive and negative affect. In Study 3, the Study-2 procedures were replicated with a separate sample of 212 golfers, except measures of excitement, concentration disruption, somatic anxiety, and worry replaced those for positive and negative affect. Structural analyses showed the findings from Study 2 were largely replicated when specific emotions were investigated in place of general indices of affect. This investigation makes novel contributions regarding the potential importance of perceptions of coach efficacy for golfers' own efficacy beliefs, and the role personal efficacy beliefs may play in facilitating the effects of performance on affective

  2. On the signatures of flare-induced global waves in the Sun: GOLF and VIRGO observations (United States)

    Kumar, Brajesh; Mathur, Savita; García, Rafael A.; Jiménez, Antonio


    Recently, several efforts have been made to identify the seismic signatures of flares and magnetic activity in the Sun and Sun-like stars. In this work, we have analysed the disc-integrated velocity and intensity observations of the Sun obtained from the Global Oscillations at Low Frequencies (GOLF) and Variability of solar IRradiance and Gravity Oscillations/Sun photometers (VIRGO/SPM) instruments, respectively, on board the Solar and Heliospheric Observatory space mission covering several successive flare events, for the period from 2011 February 11 to 2011 February 17, of which 2011 February 11 remained a relatively quiet day and served as a `null test' for the investigation. Application of the spectral analysis to these disc-integrated Sun-as-a-star velocity and intensity signals indicates that there is enhanced power of the global modes of oscillations in the Sun during the flares, as compared to the quiet day. The GOLF instrument obtains velocity observations using the Na i D lines which are formed in the upper solar photosphere, while the intensity data used in our analysis are obtained by VIRGO/SPM instrument at 862 nm, which is formed within the solar photosphere. Despite the fact that the two instruments sample different layers of the solar atmosphere using two different parameters (velocity versus intensity), we have found that both these observations show the signatures of flare-induced global waves in the Sun. These results could suffice in identifying the asteroseismic signatures of stellar flares and magnetic activity in the Sun-like stars.

  3. Nitrous Oxide Emissions from a Golf Course Fairway and Rough after Application of Different Nitrogen Fertilizers. (United States)

    Gillette, Katrina L; Qian, Yaling; Follett, Ronald F; Del Grosso, Stephen


    Few studies have quantified nitrous oxide (NO) emissions from intensively managed turfgrass systems on golf courses. Fertilizer treatments consisting of urea with inhibitors of nitrification and urease (INU), polymer-coated urea (PCU), and uncoated balanced methylene urea (BMU) chain, which use different mechanisms to control the release of N substrate, were applied to a golf course fairway and rough three times during the 2011 growing season at a rate of 50 kg N ha per application. The vented chamber method was used to measure turf-soil-atmospheric NO exchange. Cumulative emissions from fairway INU, PCU, and BMU treatments totaled 6.5, 1.9, and 7.6 kg NO-N ha yr, representing a 4.02, 1.25, and 4.75% loss of total N applied, respectively. Summer INU and BMU fertilization to the fairway produced the greatest NO fluxes. Rapid fluxes during the summer were likely related to low physiological activity in cool-season turfgrass and to warm, wet soil conditions that increased denitrification rates. However, PCU applied to the fairway was more resistant to NO losses than other fertilizer treatments. Fertilizer treatments applied to the rough had cumulative emissions of 2.4, 1.50, and 1.49 kg NO-N ha yr from INU, PCU, and BMU treatments, corresponding to a 1.21, 0.62, and 0.61% loss of total N applied, respectively. The lower NO emission on roughs was likely associated with greater carbon pools, lower soil moisture, and lower temperatures. This study supports the effectiveness of PCU to reduce NO emission from cool-season turfgrass fairways when soil conditions favored denitrification during warm periods. Applying INU and BMU when soil was cool and dry was effective in moderating NO losses.

  4. Teamwork and team training in the ICU: where do the similarities with aviation end? (United States)

    Reader, Tom W; Cuthbertson, Brian H


    The aviation industry has made significant progress in identifying the skills and behaviors that result in effective teamwork. Its conceptualization of teamwork, development of training programs, and design of assessment tools are highly relevant to the intensive care unit (ICU). Team skills are important for maintaining safety in both domains, as multidisciplinary teams must work effectively under highly complex, stressful, and uncertain conditions. However, there are substantial differences in the nature of work and structure of teams in the ICU in comparison with those in aviation. While intensive care medicine may wish to use the advances made by the aviation industry for conceptualizing team skills and implementing team training programs, interventions must be tailored to the highly specific demands of the ICU.

  5. Study of causality between civil aviation sector and economic development in Saudi Arabia

    Directory of Open Access Journals (Sweden)

    Meshaal Alshammary


    Full Text Available Recently, Saudi Arabia is undergoing major privatization and Public Private Partnership (PPP projects, as guided by the Saudi National Transformation Program (NTP 2020 and the Saudi Arabia’s Vision 2030, attempting to shift the oil-based economy toward more diverse and sustainable economy. The main purpose of the paper is to empirically examine the aviation-led growth hypothesis for Saudi Arabia by testing causality between civil aviation and economic development, applying econometric tests such as Granger causality tests for the time period from 1975 to 2011. Empirical results reveal the existence of the Civil aviation Led-Economic growth hypothesis (economic expansion causing the civil aviation sector to grow for a developing country like Saudi Arabia. As guided by both the NTP 2020 and Saudi Arabia’s Vision 2030, policy makers should consider updating civil aviation infrastructure, nation-wide airport privatization programs, increase the number of airports in major cities and establish long term partnerships with international airlines and carriers. This will strengthen the private sector and diversify the oil-based economy toward a sustainable economy.

  6. Understanding Aviation English as a Lingua Franca: Perceptions of Korean Aviation Personnel (United States)

    Kim, Hyejeong; Elder, Catherine


    Researchers exploring the use of language use in radiotelephony communication have tended to focus on the limitations of the non-native English user and the threats which their limited control of English may pose for aviation safety (e.g. Atsushi, 2003, 2004). Hence the recent International Civil Aviation Organization (ICAO) policy places the onus…

  7. Emerging trends in alternative aviation fuels (United States)

    Corbett, Cody

    The days of petroleum-based aviation fuels are numbered. New regulations to be set in place in the coming years will force current fuels to be phased out in favor of cleaner fuels with less toxic emissions. The alternative fuel industry has already taken its foothold in other modes of transportation, and aviation will soon follow suit. Many companies have cropped up over the last decade, and a few have been around longer, that work hard to develop the alternative aviation fuels of the future. It is important, however, for the aviation community to know what to expect and when to expect it concerning alternative fuels. This study investigates where various companies in the alternative aviation fuel industry currently stand in their development and production processes, and how their products will affect aircraft owners and operators. By interviewing representatives from these companies and analyzing their responses to identify trends, an educated prediction can be made about where the industry is headed and when the aviation community can expect these fuel to be available. The findings of this study indicate that many companies are still in their developmental stages, with a few notable outliers, and that most of these companies expect to see production of their product by 2017. Also, the fuel manufacturers are dealing with all the legal hurdles regarding alternative fuels, so little to no effort will be required on the part of the consumer. These findings, along with their analysis, will enable the aviation community to make educated decisions concerning fuel and their aircraft, as well and do their part to help these beneficial fuels get to market.

  8. NASA Aviation Safety Reporting System (ASRS) (United States)

    Connell, Linda J.


    The NASA Aviation Safety Reporting System (ASRS) collects, analyzes, and distributes de-identified safety information provided through confidentially submitted reports from frontline aviation personnel. Since its inception in 1976, the ASRS has collected over 1.4 million reports and has never breached the identity of the people sharing their information about events or safety issues. From this volume of data, the ASRS has released over 6,000 aviation safety alerts concerning potential hazards and safety concerns. The ASRS processes these reports, evaluates the information, and provides selected de-identified report information through the online ASRS Database at The NASA ASRS is also a founding member of the International Confidential Aviation Safety Systems (ICASS) group which is a collection of other national aviation reporting systems throughout the world. The ASRS model has also been replicated for application to improving safety in railroad, medical, fire fighting, and other domains. This presentation will discuss confidential, voluntary, and non-punitive reporting systems and their advantages in providing information for safety improvements.

  9. External costs of aviation. Background report

    Energy Technology Data Exchange (ETDEWEB)

    Dings, J.M.W.; Wit, R.C.N.; Leurs, B.A.; De Bruyn, S.M.; Davidson, M.D. [CE, Delft (Netherlands); Fransen, W. [INTEGRAL Knowledge Utilization, Landsmeer (Netherlands)


    Besides numerous benefits to citizens and companies, air transport also brings undesired side-effects such as emissions and noise nuisance. Most of these negative 'external' effects, as they are called, are currently not priced or only to a limited degree. Consequently, the market place creates insufficient incentives to reduce these external effects. The study, commissioned by the German Umweltbundesamt, aims to contribute to the ongoing international process to create market-based incentives to the aviation industry to reduce the environmental impact of aviation. It does to by assessing, within margins as small as possible, external costs of aviation. The report at hand is a background report to the study 'External costs of aviation'. It contains four technical annexes. The first annex contains an overview of the international literature on the valuation of greenhouse gas emissions. The second annex describes the dependence of climatic impact of aviation on the occurrence of contrails, and the dependence of contrail formation on operational circumstances. The third annex contains an assessment of international literature on the valuation of non-greenhouse gas emissions, such as NOx and SO2. The fourth annex contains a short description of the methodology by which emissions and noise are allocated to passenger and freight transport in this study.

  10. National General Aviation Design Competition Project Report (United States)


    This report summarizes the management of the National General Aviation Design Competition on behalf of NASA, the FAA and the Air Force by the Virginia Space Grant Consortium (VSGC) for the time period October 1, 1999 through September 30, 2000. This was the VSGC's sixth year of managing the Competition, which the Consortium originally designed, developed and implemented for NASA and the FAA. The seventh year of the Competition was announced in July 2000. Awards to winning university teams were presented at a ceremony held at AirVenture 2000, the Experimental Aircraft Association's Annual Convention and Fly-In at Oshkosh, WIS. NASA, FAA and AOPA administrators presented the awards. The competition calls for individuals or teams of undergraduate and graduate students from U.S. engineering schools to participate in a major national effort to rebuild the U.S. general aviation sector. For the purpose of the contest, General aviation aircraft are defined as fixed wing, single or dual engine (turbine or piston), single-pilot aircraft for 2-6 passengers. In addressing design challenges for a small aircraft transportation system, the competition seeks to raise student awareness of the importance of general aviation and to stimulate breakthroughs in technology and their application in the general aviation market. The Competition has two categories: Innovative Design, and Design It, Build It, Fly It. Awards were given in both categories for this reporting year.

  11. Removal of pesticides from wastewater at golf courses using plants (removal by mung beans; Phaseolus radiatus L). (United States)

    Azuma, T; Niiro, M; Motobu, H


    Many studies have been done on the removal of pollutants from wastewater using aquatic plants. Water hyacinth has been the most widely-used plant, and systems using water hyacinth are well-established. These systems, however, have a few problems in their practical use. In a previous paper, we proposed a new system that could be used as a substitute for a conventional system or, as a secondary system to assist the conventional one. Mung beans will be used to remove pollutants in this system. In the previous experiment, the removal characteristics of nutrient salts such as NO2-, NO3-, NH4+ and phosphorus salts from wastewater in residential areas were examined. Mung beans exhibited good characteristics for removing these nutrient salts. At present, pesticides used at golf courses have become a severe environmental problem polluting water supplies. The purpose of this study was, therefore, to verify whether our new system using mung beans was also effective in removing pesticides from wastewater at golf courses. An experiment was conducted on seven different pesticides. They were three insecticides; Diazinon, Fenitrothion and Chlorpyrifos, three fungicides; Captan, Isoprothiolane and Chlorothalonil, and a herbicide; Simazine. The experimental results showed that, under experimental conditions, the pesticides were rapidly removed and that they exhibited no harmful effects on the growth of the mung beans. Mung beans may be used, therefore, to remove pesticides from wastewater at golf courses although further research is needed.

  12. A revolutionary approach to composite construction and flight management systems for small, general aviation airplanes (United States)

    Roskam, Jan; Wenninger, ED


    The design studies for two composite general aviation airplanes are presented. The main consideration for both of the designs was to avoid the typical 'metal replacement' philosophy that has hindered the widespread use of composites in general aviation aircraft. The first design is for a low wing aircraft based on the Smith Aircraft Corporation GT-3 Global Trainer. The second aircraft is a composite version of the Cessna 152. The project was conducted as a graduate level design class under the auspices of the KU/NASA/USRA Advanced Design Program in aeronautics. The results obtained from the Fall semester of 1991 and the Spring semester of 1992 are presented.

  13. General Aviation Pilots Over 70 Years Old


    Vuorio, Alpo; Asmayawati, Saryani; Budowle, Bruce; Griffiths, Robin; Strandberg, Timo; Kuoppala, Jaana; Sajantila, Antti


    BACKGROUND: Currently it is not unusual for general aviation pilots in the United States to continue to fly beyond the age of 70, even into their 80s and 90s. Pilots have regular examinations according to protocols which do not specify special or additional requirements for pilots over 70 yr of age. Additionally, the third class medical reforms passed by the U.S. Senate on 15 July 2016 could potentially result in even less stringent medical certification requirements for general aviation pilo...

  14. Selected supplies prognosis problems of aviation techniques (United States)

    Żurek, J.; Czapla, R.


    Aviation technology, i.e. aircraft, control and airfield infrastructure wear out, become defective and need servicing. It seems indispensible to maintain facilities and spare parts at a level necessary to keep the technology in commission. The paper discusses the factors influencing spare parts supply requirements to secure air operations. Aviation technology has been classified with regard to various criteria, which influence the choice of supply management strategies, along with availability and aircraft exploitation cost. The method of optimization of the stock for a complex system characterized by series reliability structure according to the wear-out and cost criteria assuming Poisson's process of demand has been presented.

  15. Causal Factors and Adverse Events of Aviation Accidents and Incidents Related to Integrated Vehicle Health Management (United States)

    Reveley, Mary S.; Briggs, Jeffrey L.; Evans, Joni K.; Jones, Sharon M.; Kurtoglu, Tolga; Leone, Karen M.; Sandifer, Carl E.


    Causal factors in aviation accidents and incidents related to system/component failure/malfunction (SCFM) were examined for Federal Aviation Regulation Parts 121 and 135 operations to establish future requirements for the NASA Aviation Safety Program s Integrated Vehicle Health Management (IVHM) Project. Data analyzed includes National Transportation Safety Board (NSTB) accident data (1988 to 2003), Federal Aviation Administration (FAA) incident data (1988 to 2003), and Aviation Safety Reporting System (ASRS) incident data (1993 to 2008). Failure modes and effects analyses were examined to identify possible modes of SCFM. A table of potential adverse conditions was developed to help evaluate IVHM research technologies. Tables present details of specific SCFM for the incidents and accidents. Of the 370 NTSB accidents affected by SCFM, 48 percent involved the engine or fuel system, and 31 percent involved landing gear or hydraulic failure and malfunctions. A total of 35 percent of all SCFM accidents were caused by improper maintenance. Of the 7732 FAA database incidents affected by SCFM, 33 percent involved landing gear or hydraulics, and 33 percent involved the engine and fuel system. The most frequent SCFM found in ASRS were turbine engine, pressurization system, hydraulic main system, flight management system/flight management computer, and engine. Because the IVHM Project does not address maintenance issues, and landing gear and hydraulic systems accidents are usually not fatal, the focus of research should be those SCFMs that occur in the engine/fuel and flight control/structures systems as well as power systems.

  16. Reducing Aviation Weather-Related Accidents Through High-Fidelity Weather Information Distribution and Presentation (United States)

    Stough, H. Paul, III; Shafer, Daniel B.; Schaffner, Philip R.; Martzaklis, Konstantinos S.


    In February 1997, the US President announced a national goal to reduce the fatal accident rate for aviation by 80% within ten years. The National Aeronautics and Space Administration established the Aviation Safety Program to develop technologies needed to meet this aggressive goal. Because weather has been identified (is a causal factor in approximately 30% of all aviation accidents, a project was established for the development of technologies that will provide accurate, time and intuitive information to pilots, dispatchers, and air traffic controllers to enable the detection and avoidance of atmospheric hazards. This project addresses the weather information needs of general, corporate, regional, and transport aircraft operators. An overview and status of research and development efforts for high-fidelity weather information distribution and presentation is discussed with emphasis on weather information in the cockpit.

  17. Effect of Putting Grip on Eye and Head Movements During the Golf Putting Stroke

    Directory of Open Access Journals (Sweden)

    George K. Hung


    Full Text Available The objective of this article is to determine the effect of three different putting grips (conventional, cross-hand, and one-handed on variations in eye and head movements during the putting stroke. Seven volunteer novice players, ranging in age from 21 to 22 years, participated in the study. During each experimental session, the subject stood on a specially designed platform covered with artificial turf and putted golf balls towards a standard golf hole. The three different types of grips were tested at two distances: 3 and 9 ft. For each condition, 20 putts were attempted. For each putt, data were recorded over a 3-s interval at a sampling rate of 100 Hz. Eye movements were recorded using a helmet-mounted eye movement monitor. Head rotation about an imaginary axis through the top of the head and its center-of-rotation was measured by means of a potentiometer mounted on a fixed frame and coupled to the helmet. Putter-head motion was measured using a linear array of infrared phototransistors embedded in the platform. The standard deviation (STD, relative to the initial level was calculated for eye and head movements over the duration of the putt (i.e., from the beginning of the backstroke, through the forward stroke, to impact. The averaged STD for the attempted putts was calculated for each subject. Then, the averaged STDs and other data for the seven subjects were statistically compared across the three grip conditions. The STD of eye movements were greater (p < 0.1 for conventional than cross-hand (9 ft and one-handed (3 and 9 ft grips. Also, the STD of head movements were greater (p < 0.1; 3 ft for conventional than cross-hand and one-handed grips. Vestibulo-ocular responses associated with head rotations could be observed in many 9 ft and some 3 ft putts. The duration of the putt was significantly longer (p < 0.05; 3 and 9 ft for the one-handed than conventional and cross-hand grips. Finally, performance, or percentage putts made, was

  5. Technologies to counter aviation security threats (United States)

    Karoly, Steve


    The Aviation and Transportation Security Act (ATSA) makes TSA responsible for security in all modes of transportation, and requires that TSA assess threats to transportation, enforce security-related regulations and requirements, and ensure the adequacy of security measures at airports and other transportation facilities. Today, TSA faces a significant challenge and must address a wide range of commercial, military grade, and homemade explosives and these can be presented in an infinite number of configurations and from multiple vectors. TSA screens 2 million passengers and crew, and screens almost 5 million carry-on items and 1.2 million checked bags daily. As TSA explores new technologies for improving efficiency and security, those on the forefront of research and development can help identify unique and advanced methods to combat terrorism. Research and Development (R&D) drives the development of future technology investments that can address an evolving adversary and aviation threat. The goal is to rethink the aviation security regime in its entirety, and rather than focusing security at particular points in the enterprise, distribute security from the time a reservation is made to the time a passenger boards the aircraft. The ultimate objective is to reengineer aviation security from top to bottom with a continued focus on increasing security throughout the system.

  7. Impact of aviation upon the atmosphere. Introduction

    Energy Technology Data Exchange (ETDEWEB)

    Carpentier, J. [Comite Avion-Ozone, 75 - Paris (France)


    The commercial air traffic, either for business or for tourism will induce a special increase of long haul flights, with cruising altitudes of about 10 to 12 km. These altitudes correspond to the upper troposphere for the low latitudes (tropical zones) and to the lower stratosphere for middle and high latitudes. The prospect of a world air traffic multiplied by a factor 2 within the next fifteen years, with an increasing part of the long-haul flights, raises the problem of the impact of aircraft emissions on the upper troposphere and on the lower stratosphere. The air traffic growth which is forecast for the next two decades as well as for long term will be larger than the GDP growth. But technical progress concerning airframes, engines, navigation systems and improvements of air traffic control and airports will keep the aircraft emissions growth at a rate which will not exceed the GDP growth rate. The aviation`s share of global anthropogenic emissions will remain lower than 3 percent. The regulations related to NO{sub x} emissions from aircraft will reduce the aviation`s share of nitrogen oxides from human sources at a level of 1 percent. (R.P.)

  4. The UNO Aviation Monograph Series: Aviation Security: An Annotated Bibliography of Responses to the Gore Commission (United States)

    Carrico, John S.; Schaaf, Michaela M.


    This monograph is a companion to UNOAI Monograph 96-2, "The Image of Airport Security: An Annotated Bibliography," compiled in June 1996. The White House Commission on Aviation Safety and Security, headed by Vice President Al Gore, was formed as a result of the TWA Flight 800 crash in August 1996. The Commission's final report included 31 recommendations addressed toward aviation security. The recommendations were cause for security issues to be revisited in the media and by the aviation industry. These developments necessitated the need for an updated bibliography to review the resulting literature. Many of the articles were written in response to the recommendations made by the Gore Commission. "Aviation Security: An Annotated Bibliography of Responses to the Gore Commission" is the result of this need.

  6. Spine biomechanics associated with the shortened, modern one-plane golf swing. (United States)

    Dale, R Barry; Brumitt, Jason


    The purpose of this study was to compare kinetic, kinematic, and performance variables associated with full and shortened modern backswings in a skilled group of modern swing (one-plane) golfers. Shortening the modern golf backswing is proposed to reduce vertebral spine stress, but supporting evidence is lacking and performance implications are unknown. Thirteen male golfers performed ten swings of each swing type using their own 7-iron club. Biomechanical-dependent variables included the X-Factor kinematic data and spine kinetics. Performance-related dependent variables included club head velocity (CHV), shot distance, and accuracy (distance from the target line). Data were analysed with repeated measures ANOVA with an a priori alpha of 0.05 (SPSS 22.0, IBM, Armonk, NY, USA). We found significant reductions for the X-Factor (p < 0.05) between the full and shortened swings. The shortened swing condition ameliorated vertebral compression force from 7.6 ± 1.4 to 7.0 ± 1.7 N (normalised to body weight, p = 0.01) and significantly reduced CHV (p < 0.05) by ~2 m/s with concomitant shot distance diminution by ~10 m (p < 0.05). Further research is necessary to examine the applicability of a shortened swing for golfers with low back pain.

  7. Random Versus Blocked Practice to Enhance Mental Representation in Golf Putting. (United States)

    Fazeli, Davoud; Taheri, HamidReza; Saberi Kakhki, Alireza


    The purpose of this study was to investigate changes in mental representation from either random or blocked practice when engaged in golf putting. Thirty participants were randomly assigned to random practice, blocked practice, and no-practice groups. First, we measured novice golfers' initial mental representation levels and required them to perform 18 putting trials as a pre-test. We then asked random and blocked groups to practice in accordance with their group assignment for six consecutive days (10 blocks each day, 18 trials each). A week after the last practice session, we re-measured all participants' final mental representation levels and required them to perform 18 putting trials to evaluate learning retention through practice. While those engaged in the random practice method putted more poorly during acquisition (i.e., practice) than those in blocked practice, the random practice group experienced more accurate retention during the final putting trials, and they showed a more structured mental representation than those in blocked practice, one that was more similar to that of skilled golfers. These results support the acquisition of a rich mental representation through random versus blocked practice.

  8. The relationship between the golf swing plane and ball impact characteristics using trajectory ellipse fitting. (United States)

    Morrison, Andrew; McGrath, Denise; Wallace, Eric S


    The trajectory of the clubhead close to ball impact during the golf swing has previously been shown to be planar. However, the relationship between the plane orientation and the orientation characteristics of the clubhead at ball impact has yet to be defined. Fifty-two male golfers (27 high skilled, 25 intermediate skilled) hit 40 drives each in an indoor biomechanics laboratory. This study successfully fitted the trajectory of the clubhead near impact to an ellipse for each swing for players of different skill levels to help better explain this relationship. Additionally, the eccentricities of the ellipses were investigated for links to skill level. The trajectory of the clubhead was found to fit to an ellipse with RMSE of 1.2 mm. The eccentricity of the ellipse was found to be greater in the high-skilled golfers. The club path and angle of attack generated from the ellipse fitted clubhead trajectory were found to have a normalised bias-corrected RMSE of 2% and 3%, respectively. A set of "rule of thumb" values for the relationship between the club path, angle of attack and delivery plane angle was generated for use by coaches.

  9. No transfer of calibration between action and perception in learning a golf putting task. (United States)

    Van Lier, Wim; Van der Kamp, John; van der Zanden, Anne; Savelsbergh, Geert J P


    We assessed calibration of perception and action in the context of a golf putting task. Previous research has shown that right-handed novice golfers make rightward errors both in the perception of the perfect aiming line from the ball to the hole and in the putting action. Right-handed experts, however, produce accurate putting actions but tend to make leftward errors in perception. In two experiments, we examined whether these skill-related differences in directional error reflect transfer of calibration from action to perception. In the main experiment, three groups of right-handed novice participants followed a pretest, practice, posttest, retention test design. During the tests, directional error for the putting action and the perception of the perfect aiming line were determined. During practice, participants were provided only with verbal outcome feedback about directional error; one group trained perception and the second trained action, whereas the third group did not practice. Practice led to a relatively permanent annihilation of directional error, but these improvements in accuracy were specific to the trained task. Hence, no transfer of calibration occurred between perception and action. The findings are discussed within the two-visual-system model for perception and action, and implications for perceptual learning in action are raised.

  10. Sun Rivers Golf Resort Community : Canada's only geo thermally heated and cooled community

    Energy Technology Data Exchange (ETDEWEB)

    Brochu, L. [Sun Rivers Development, Kamloops, BC (Canada)


    This presentation described the development of Canada's only geothermal district heating and cooling system at the Sun Rivers Golf Resort Community near Kamloops, British Columbia. Geothermal systems exchange heat with the ground to efficiently heat and cool buildings. The decision to use geothermal energy was based on the fact that ground source heating and cooling offers 50 per cent savings and 300 per cent efficiency. In addition, it is environmentally friendly, totally renewable with no carbon dioxide emissions or odours. In the winter, ground source heat pumps are a heat source, moving heat from the earth to buildings. In the heating mode, heat is extracted from the fluid in the earth connection by the geothermal heat pump and distributed to the building through a system of air ducts. In the summer, the ground source heat pump acts as a heat sink, moving the heat away from the building. In the cooling mode, the cool fluid from the earth connection absorbs heat from the building and transfers it to the ground. This presentation described how the municipality and the developer worked together to ensure the success of the geothermal district heating and cooling system. Homeowners pay a reasonable monthly geothermal access fee. The project has been financially rewarding. 2 tabs., 16 figs.

  11. [Research and workshop on alternative fuels for aviation. Final report

    Energy Technology Data Exchange (ETDEWEB)



    The Renewable Aviation Fuels Development Center (RAFDC) at Baylor University was granted U. S. Department of Energy (US DOE) and Federal Aviation Administration (FAA) funds for research and development to improve the efficiency in ethanol powered aircraft, measure performance and compare emissions of ethanol, Ethyl Tertiary Butyl Ether (ETBE) and 100 LL aviation gasoline. The premise of the initial proposal was to use a test stand owned by Engine Components Inc. (ECI) based in San Antonio, Texas. After the grant was awarded, ECI decided to close down its test stand facility. Since there were no other test stands available at that time, RAFDC was forced to find additional support to build its own test stand. Baylor University provided initial funds for the test stand building. Other obstacles had to be overcome in order to initiate the program. The price of the emission testing equipment had increased substantially beyond the initial quote. Rosemount Analytical Inc. gave RAFDC an estimate of $120,000.00 for a basic emission testing package. RAFDC had to find additional funding to purchase this equipment. The electronic ignition unit also presented a series of time consuming problems. Since at that time there were no off-the-shelf units of this type available, one had to be specially ordered and developed. FAA funds were used to purchase a Super Flow dynamometer. Due to the many unforeseen obstacles, much more time and effort than originally anticipated had to be dedicated to the project, with much of the work done on a volunteer basis. Many people contributed their time to the program. One person, mainly responsible for the initial design of the test stand, was a retired engineer from Allison with extensive aircraft engine test stand experience. Also, many Baylor students volunteered to assemble the. test stand and continue to be involved in the current test program. Although the program presented many challenges, which resulted in delays, the RAFDC's test

  12. Energy Beverage Consumption Among Naval Aviation Candidates. (United States)

    Sather, Thomas E; Delorey, Donald R


    Since the debut of energy beverages, the consumption of energy beverages has been immensely popular with young adults. Research regarding energy beverage consumption has included college students, European Union residents, and U.S. Army military personnel. However, energy beverage consumption among naval aviation candidates in the United States has yet to be examined. The purpose of this study was to assess energy beverage consumption patterns (frequency and volume) among naval aviation candidates, including attitudes and perceptions regarding the benefits and safety of energy beverage consumption. A 44-item survey was used to assess energy beverage consumption patterns of 302 students enrolled in the Aviation Preflight Indoctrination Course at Naval Air Station Pensacola, FL. Results indicated that 79% of participants (N = 239) reported consuming energy beverages within the last year. However, of those who reported consuming energy beverages within the last year, only 36% (N = 85) reported consuming energy beverages within the last 30 d. Additionally, 51% (N = 153) of participants reported no regular energy beverages consumption. The majority of participants consumed energy beverages for mental alertness (67%), mental endurance (37%), and physical endurance (12%). The most reported side effects among participants included increased mental alertness (67%), increased heart rate (53%), and restlessness (41%). Naval aviation candidates appear to use energy drinks as frequently as a college student population, but less frequently than expected for an active duty military population. The findings of this study indicate that naval aviation candidates rarely use energy beverages (less than once per month), but when consumed, they use it for fatigue management.

  17. [Personal traits and a sense of job-related stress in a military aviation crew]. (United States)

    Cabarkapa, Milanko; Korica, Vesna; Rodjenkov, Sanja


    Accelerated technological and organizational changes in numerous professions lead to increase in job-related stress. Since these changes are particularly common in military aviation, this study examined the way military aviation crew experiences job-related stress during a regular aviation drill, depending on particular social-demographic factors and personal traits. The modified Cooper questionnaire was used to examine the stress related factors at work. The questionnaire was adapted for the aviation crew in the army environment. Personal characteristics were examined using the NEO-PI-R personality inventory. The study included 50 examinees (37 pilots and 13 other crew members) employed in the Serbian Army. The studies were performed during routine physical examinations at the Institute for Aviation Medicine during the year 2007. Statistical analysis of the study results contained descriptive analysis, one-way analysis of variance and correlation analysis. It was shown that army aviation crew works under high stress. The highest stress value had the intrinsic factor (AS = 40.94) and role in organisation (AS = 39.92), while the lowest one had the interpersonal relationship factor (AS = 29.98). The results also showed that some social-demographic variables (such as younger examinees, shorter working experience) and neuroticism as a personality trait, were in correlation with job-related stress. Stress evaluation and certain personality characteristics examination can be used for the development of the basic anti-stress programs and measures in order to achieve better psychological selection, adaptation career leadership and organization of military pilots and other crew members.

  19. Modelling climate impacts on the aviation sector (United States)

    Williams, Paul


    The climate is changing, not just where we live at ground level, but also where we fly at 35,000 feet. We have long known that air travel contributes to climate change through its emissions. However, we have only recently become aware that climate change could have significant consequences for air travel. This presentation will give an overview of the possible impacts of climate change on the aviation sector. The presentation will describe how the impacts are modelled and how their social and economic costs are estimated. The impacts are discussed in the International Civil Aviation Organization's (ICAO's) latest Environmental Report (Puempel and Williams 2016). Some of the possible impacts are as follows. Rising sea levels and storm surges threaten coastal airports, such as La Guardia in New York, which was flooded by the remnants of Hurricane Sandy in 2012. Warmer air at ground level reduces the lift force and makes it more difficult for planes to take-off (Coffel and Horton 2015). More extreme weather may cause flight disruptions and delays. Clear-air turbulence is expected to become up to 40% stronger and twice as common (Williams and Joshi 2013). Transatlantic flights may collectively be airborne for an extra 2,000 hours each year because of changes to the jet stream, burning an extra 7.2 million gallons of jet fuel at a cost of US 22 million, and emitting an extra 70 million kg of carbon dioxide (Williams 2016). These modelled impacts provide further evidence of the two-way interaction between aviation and climate change.

  20. Synthetic and Biomass Alternate Fueling in Aviation (United States)

    Hendricks, R. C.; Bushnell, D. M.


    While transportation fueling can accommodate a broad range of alternate fuels, aviation fueling needs are specific, such as the fuel not freezing at altitude or become too viscous to flow properly or of low bulk energy density that shortens range. The fuel must also be compatible with legacy aircraft, some of which are more than 50 years old. Worldwide, the aviation industry alone uses some 85-95 billion gallons of hydrocarbon-based fossil fuel each year, which is about 10% of the transportation industry. US civil aviation alone consumes nearly 14 billion gallons. The enormity of the problem becomes overwhelming, and the aviation industry is taking alternate fueling issues very seriously. Biofuels (algae, cyanobacteria, halophytes, weeds that use wastelands, wastewater and seatwater), when properly sourced, have the capacity to be drop-in fuel replacements for petroleum fuels. As such, biojet from such sources solves the aviation CO2 emissions issue without the downsides of 'conventional' biofuels, such as competing with food and fresh water resources. Of the many current fundamental problems, the major biofuel problem is cost. Both research and development and creative engineering are required to reduce these biofuels costs. Research is also ongoing in several 'improvement' areas including refining/processing and biologics with greater disease resistance, greater bio-oil productivity, reduced water/nutrient requirements, etc. The authors' current research is aimed at aiding industry efforts in several areas. They are considering different modeling approaches, growth media and refining approaches, different biologic feedstocks, methods of sequestering carbon in the processes, fuel certification for aviation use and, overall, ensuring that biofuels are feasible from all aspects - operability, capacity, carbon cycle and financial. The authors are also providing common discussion grounds/opportunities for the various parties, disciplines and concerned organization to

  1. [Psychopharmacology in aviation and astronautics]. (United States)

    Vasil'ev, P V; Glod, G D


    Flights aboard modern vehicles are associated with high nervous-emotional and physical stresses. This may induce depletion of reserve capabilities, development of fatigue and, consequently, reduction of work capacity of crewmembers. The paper discusses approaches and results of the use of drugs by pilots and cosmonauts in order to alleviate their fatigue and emotional stress. It gives indications and contraindications for the adminstration of stimulants and tranquilizers. On the basis of a comprehensive analysis of the literature data and their own findings, the authors draw the conclusion that the use of stimulants and anxiolytics may increase the level of reliability and performance of air- and spacecraft pilots during programmed and, particularly, contigent situations of the flight.

  2. Demonstration and implementation of ethanol as an aviation fuel. Final report

    Energy Technology Data Exchange (ETDEWEB)



    The objectives of the program were to demonstrate the viability of ethanol as an aviation fuel at appropriate locations and audiences in the participating Biomass Energy Program Regions, and to promote implementation projects in the area. Seven demonstrations were to be performed during the Summer 1995 through December 1996 period. To maximize the cost effectiveness of the program, additional corporate co-sponsorships were sought at each demonstration site and the travel schedule was arranged to take advantage of appropriate events taking place in the vicinity of the schedule events or enroute. This way, the original funded amount was stretched to cover another year of activities increasing the number of demonstrations from seven to thirty-nine. While the Renewable Aviation Fuels Development Center (RAFDC) contract focused on ethanol as an aviation fuel, RAFDC also promoted the broader use of ethanol as a transportation fuel. The paper summarizes locations and occasions, and gives a brief description of each demonstration/exhibit/presentation held during the term of the project. Most of the demonstrations took place at regularly scheduled air shows, such as the Oshkosh, Wisconsin Air Show. The paper also reviews current and future activities in the areas of certification, emission testing, the international Clean Airports Program, air pollution monitoring with instrumented aircraft powered by renewable fuels, training operation and pilot project on ethanol, turbine fuel research, and educational programs.

  3. Synthetic and Biomass Alternate Fueling in Aviation (United States)

    Hendricks, R.C.; Bushnell, D.M.


    Worldwide, aviation alone uses 85 to 95 billion gallons of nonrenewable fossil fuel per year (2008). General transportation fueling can accommodate several different fuels; however, aviation fuels have very specific requirements. Biofuels have been flight demonstrated, are considered renewable, have the capacity to become "drop-in" replacements for Jet-A fuel, and solve the CO2 climate change problem. The major issue is cost; current biomass biofuels are not economically competitive. Biofuel feedstock sources being researched are halophytes, algae, cyanobacteria, weeds-to-crops, wastes with contingent restraints on use of crop land, freshwater, and climate change. There are five major renewable energy sources: solar thermal, solar photovoltaic, wind, drilled geothermal and biomass, each of which have an order of magnitude greater capacity to meet all energy needs. All five address aspects of climate change; biomass has massive potential as an energy fuel feedstock.

  4. Skin in aviation and space environment. (United States)

    Grover, Sanjiv


    The aerospace environment is a dynamic interaction between man, machine and the environment. Skin diseases are not particularly significant aeromedically, yet they could permanently affect an aviator's status for continued flying duty. A number of dermatological conditions lend themselves to flying restrictions for the aviator. Aircrew and ground crew are exposed to a myriad of elements that could also adversely impact their flying status. Inflight stresses during flights as well as space travel could impact certain behaviors from a dermatological standpoint. With the advent of space tourism, dermatological issues would form an integral part of medical clearances. With limited literature available on this subject, the review article aims to sensitize the readers to the diverse interactions of dermatology with the aerospace environment.

  5. Competitive elite golf: a review of the relationships between playing results, technique and physique. (United States)

    Hellström, John


    Elite golfers commonly use fitness and technical training to become more competitive. The aim of this paper was to review the literature regarding the relationships between elite golfers' playing results, technique and physique. The competitive outcome is a direct function of the score. The three golf statistical measures that show the strongest correlations to scoring average are greens in regulation (GIR), scrambling, and putts per GIR. However, more detailed game statistics are needed where the distances to the targets are known before and after the strokes. Players affect ball displacement by controlling clubhead velocity and clubface angle during club and ball impact. X-factor studies have produced ambiguous results, possibly caused by different definitions of upper torso, rotation and top of backswing. Higher clubhead speed is generally associated with larger spinal rotation and shoulder girdle protraction at the top of the backswing. It is also associated with higher ground reaction forces and torques, a bottom-up and sequential increase of body segment angular velocities, a rapid increase of spinal rotation and a late adduction of the wrists during the downswing. Players can increase the clubhead speed generated by a swinging motion by actively adding a force couple. Wrist, elbow and shoulder force couple strategies should be differentiated when investigating the technique. Physical parameters such as anthropometrics, strength and flexibility are associated with skill level and clubhead speed. Current studies have investigated the linear correlation between arm and shaft lengths and clubhead speed, but a quadratic relationship may be stronger due to changes in moment of inertia. Fitness training can increase and perhaps decrease the clubhead speed and striking distance, depending on training methods and the player's fitness and level of skill. Future studies may focus on individual training needs and the relationship between physique, execution and its

  7. Caffeine Consumption Among Naval Aviation Candidates. (United States)

    Sather, Thomas E; Williams, Ronald D; Delorey, Donald R; Woolsey, Conrad L


    Education frequently dictates students need to study for prolonged periods of time to adequately prepare for examinations. This is especially true with aviation preflight indoctrination (API) candidates who have to assimilate large volumes of information in a limited amount of time during API training. The purpose of this study was to assess caffeine consumption patterns (frequency, type, and volume) among naval aviation candidates attending API to determine the most frequently consumed caffeinated beverage and to examine if the consumption of a nonenergy drink caffeinated beverage was related to energy drink consumption. Data were collected by means of an anonymous 44-item survey administered and completed by 302 students enrolled in API at Naval Air Station Pensacola, FL. Results indicated the most frequently consumed caffeinated beverage consumed by API students was coffee (86.4%), with daily coffee consumption being approximately 28% and the most frequent pattern of consumption being 2 cups per day (85%). The least frequently consumed caffeinated beverages reported were energy drinks (52%) and energy shots (29.1%). The present study also found that the consumption patterns (weekly and daily) of caffeinated beverages (coffee and cola) were positively correlated to energy drink consumption patterns. Naval aviation candidates' consumption of caffeinated beverages is comparable to other college and high school cohorts. This study found that coffee and colas were the beverages of choice, with energy drinks and energy shots being the least frequently reported caffeinated beverages used. Additionally, a relationship between the consumption of caffeinated beverages and energy drinks was identified.Sather TE, Williams RD, Delorey DR, Woolsey CL.

  11. Psychophysiology of Spaceflight and Aviation (United States)

    Cowings, Patricia; Toscano, William


    In space, the absence of gravity alone causes unique physiological stress. Significant biomedical changes, across multiple organ systems, such as body fluid redistribution, diminished musculoskeletal strength, changes in cardiac function and sensorimotor control have been reported. The time course of development of these disorders and severity of symptoms experienced by individuals varies widely. Space motion sickness (SMS) is an example of maladaptation to microgravity, which occurs early in the mission and can have profound effects on physical health and crew performance. Disturbances in sleep quality, perception, emotional equilibrium and mood have also been reported, with impact to health and performance varying widely across individuals. And lastly, post-flight orthostatic intolerance, low blood pressure experienced after returning to Earth, is also of serious concern. Both the Russian and American space programs have a varied list of human errors and mistakes, which adversely impacted mission goals. Continued probability of human exposure to microgravity for extended time periods provides a rationale for the study of the effects of stress. The primary focus of this research group is directed toward examining individual differences in: (a) prediction of susceptibility to these disorders, (b) assessment of symptom severity, (c) evaluation of the effectiveness of countermeasures, and (d) developing and testing a physiological training method, Autogenic-Feedback Training Exercise (AFTE) as a countermeasure with multiple applications. The present paper reports on the results of a series of human flight experiments with AFTE aboard the Space Shuttle and Mir Space Station, and during emergency flight scenarios on Earth.

  15. Fatigue Behaviors of 2024 Aluminum Alloy under Aviation Load Spectrum

    Directory of Open Access Journals (Sweden)

    CHEN Yajun


    Full Text Available The fatigue properties of 2024 aluminum alloy under the influence of TWIST on the aviation load spectrum were studied. The aircraft load spectrum was simplified, and the fatigue life of the aircraft was predicted by theoretical analysis, MATLAB program simulation and fatigue was test, and the failure mechanism was observed. The results show that the predicted values of fatigue life are 163800, 158280 and 134249 respectively. Aircraft cruise loads during actual gust load spectrum is simulated, the minimal fluctuation spectrum is ignored. The flight cycles are 92314 and 92321 times respectively. Crack initiation nucleation is originated in the test piece near the surface. Fatigue crack is propagated between intergranular and transcrystalline rupture. Instantaneous, rupture zone and crack propagation can be observed.

  16. Human Factors Directions for Civil Aviation (United States)

    Hart, Sandra G.


    Despite considerable progress in understanding human capabilities and limitations, incorporating human factors into aircraft design, operation, and certification, and the emergence of new technologies designed to reduce workload and enhance human performance in the system, most aviation accidents still involve human errors. Such errors occur as a direct or indirect result of untimely, inappropriate, or erroneous actions (or inactions) by apparently well-trained and experienced pilots, controllers, and maintainers. The field of human factors has solved many of the more tractable problems related to simple ergonomics, cockpit layout, symbology, and so on. We have learned much about the relationships between people and machines, but know less about how to form successful partnerships between humans and the information technologies that are beginning to play a central role in aviation. Significant changes envisioned in the structure of the airspace, pilots and controllers' roles and responsibilities, and air/ground technologies will require a similarly significant investment in human factors during the next few decades to ensure the effective integration of pilots, controllers, dispatchers, and maintainers into the new system. Many of the topics that will be addressed are not new because progress in crucial areas, such as eliminating human error, has been slow. A multidisciplinary approach that capitalizes upon human studies and new classes of information, computational models, intelligent analytical tools, and close collaborations with organizations that build, operate, and regulate aviation technology will ensure that the field of human factors meets the challenge.

  17. Global civil aviation black carbon emissions. (United States)

    Stettler, Marc E J; Boies, Adam M; Petzold, Andreas; Barrett, Steven R H


    Aircraft black carbon (BC) emissions contribute to climate forcing, but few estimates of BC emitted by aircraft at cruise exist. For the majority of aircraft engines the only BC-related measurement available is smoke number (SN)-a filter based optical method designed to measure near-ground plume visibility, not mass. While the first order approximation (FOA3) technique has been developed to estimate BC mass emissions normalized by fuel burn [EI(BC)] from SN, it is shown that it underestimates EI(BC) by >90% in 35% of directly measured cases (R(2) = -0.10). As there are no plans to measure BC emissions from all existing certified engines-which will be in service for several decades-it is necessary to estimate EI(BC) for existing aircraft on the ground and at cruise. An alternative method, called FOX, that is independent of the SN is developed to estimate BC emissions. Estimates of EI(BC) at ground level are significantly improved (R(2) = 0.68), whereas estimates at cruise are within 30% of measurements. Implementing this approach for global civil aviation estimated aircraft BC emissions are revised upward by a factor of ~3. Direct radiative forcing (RF) due to aviation BC emissions is estimated to be ~9.5 mW/m(2), equivalent to ~1/3 of the current RF due to aviation CO2 emissions.

  18. Using random forests to diagnose aviation turbulence. (United States)

    Williams, John K

    Atmospheric turbulence poses a significant hazard to aviation, with severe encounters costing airlines millions of dollars per year in compensation, aircraft damage, and delays due to required post-event inspections and repairs. Moreover, attempts to avoid turbulent airspace cause flight delays and en route deviations that increase air traffic controller workload, disrupt schedules of air crews and passengers and use extra fuel. For these reasons, the Federal Aviation Administration and the National Aeronautics and Space Administration have funded the development of automated turbulence detection, diagnosis and forecasting products. This paper describes a methodology for fusing data from diverse sources and producing a real-time diagnosis of turbulence associated with thunderstorms, a significant cause of weather delays and turbulence encounters that is not well-addressed by current turbulence forecasts. The data fusion algorithm is trained using a retrospective dataset that includes objective turbulence reports from commercial aircraft and collocated predictor data. It is evaluated on an independent test set using several performance metrics including receiver operating characteristic curves, which are used for FAA turbulence product evaluations prior to their deployment. A prototype implementation fuses data from Doppler radar, geostationary satellites, a lightning detection network and a numerical weather prediction model to produce deterministic and probabilistic turbulence assessments suitable for use by air traffic managers, dispatchers and pilots. The algorithm is scheduled to be operationally implemented at the National Weather Service's Aviation Weather Center in 2014.

  19. Perspectives for Sustainable Aviation Biofuels in Brazil

    Directory of Open Access Journals (Sweden)

    Luís A. B. Cortez


    Full Text Available The aviation industry has set ambitious goals to reduce carbon emissions in coming decades. The strategy involves the use of sustainable biofuels, aiming to achieve benefits from environmental, social, and economic perspectives. In this context, Brazilian conditions are favorable, with a mature agroindustry that regularly produces automotive biofuel largely adopted by Brazilian road vehicles, while air transportation has been growing at an accelerating pace and a modern aircraft industry is in place. This paper presents the main conclusions and recommendations from a broad assessment of the technological, economic, and sustainability challenges and opportunities associated with the development of drop-in aviation biofuels in Brazil. It was written by a research team that prepared the initial reports and conducted eight workshops with the active participation of more than 30 stakeholders encompassing the private sector, government institutions, NGOs, and academia. The main outcome was a set of guidelines for establishing a new biofuels industry, including recommendations for (a filling the identified research and development knowledge gaps in the production of sustainable feedstock; (b overcoming the barriers in conversion technology, including scaling-up issues; (c promoting greater involvement and interaction between private and government stakeholders; and (d creating a national strategy to promote the development of aviation biofuels.

  20. Aviation Fueling: A Cleaner, Greener Approach (United States)

    Hendricks, Robert C.; Bushnell, Dennis M.; Shouse, Dale T.


    Projected growth of aviation depends on fueling where specific needs must be met. Safety is paramount, and along with political, social, environmental and legacy transport systems requirements, alternate aviation fueling becomes an opportunity of enormous proportions. Biofuels sourced from halophytes, algae, cyanobacteria, and weeds using wastelands, waste water, and seawater have the capacity to be drop-in fuel replacements for petroleum fuels. Biojet fuels from such sources solves the aviation CO2 emissions issue and do not compete with food or freshwater needs. They are not detrimental to the social or environmental fabric and use the existing fuels infrastructure. Cost and sustainable supply remains the major impediments to alternate fuels. Halophytes are the near-term solution to biomass/biofuels capacity at reasonable costs; they simply involve more farming, at usual farming costs. Biofuels represent a win-win approach, proffering as they do at least the ones we are studying massive capacity, climate neutral-to-some sequestration, and ultimately, reasonable costs.

  4. Aviation suicide: a review of general aviation accidents in the UK, 1970-96. (United States)

    Cullen, S A


    A review was undertaken of 415 general aviation accidents. Three were definite cases of suicide and in another seven it seemed possible that the deceased had taken their own lives. Therefore, in the United Kingdom, suicide definitely accounts for 0.72% of general aviation accidents and possibly for more than 2.4%. The latter accords more closely with the findings from Germany than from the United States. Previous psychiatric or domestic problems and alcohol misuse are features of these cases. Aerobatics before the final impact is another frequent finding. The investigation of fatal accidents involving "pilot error" is incomplete without an examination of the victim's social and psychological history. An assessment of a pilot's mental well-being is an essential part of aviation medical examinations.

    This book discusses the emerging field of industrial neuroscience, and reports on the authors’ cutting-edge findings in the evaluation of mental states, including mental workload, cognitive control and training of personnel involved either in the piloting of aircraft and helicopters, or in managing air traffic. It encompasses neuroimaging and cognitive psychology techniques and shows how they have been successfully applied in the evaluation of human performance and human-machine interactions, and to guarantee a proper level of safety in such operational contexts. With an introduction to the most relevant concepts of neuroscience, neurophysiological techniques, simulators and case studies in aviation environments, it is a must-have for both students and scientists in the field of aeronautic and biomedical engineering, as well as for various professionals in the aviation world. This is the first book to intensively apply neurosciences to the evaluation of human factors and mental states in aviation.

  6. System for Secure Integration of Aviation Data (United States)

    Kulkarni, Deepak; Wang, Yao; Keller, Rich; Chidester, Tom; Statler, Irving; Lynch, Bob; Patel, Hemil; Windrem, May; Lawrence, Bob


    The Aviation Data Integration System (ADIS) of Ames Research Center has been established to promote analysis of aviation data by airlines and other interested users for purposes of enhancing the quality (especially safety) of flight operations. The ADIS is a system of computer hardware and software for collecting, integrating, and disseminating aviation data pertaining to flights and specified flight events that involve one or more airline(s). The ADIS is secure in the sense that care is taken to ensure the integrity of sources of collected data and to verify the authorizations of requesters to receive data. Most importantly, the ADIS removes a disincentive to collection and exchange of useful data by providing for automatic removal of information that could be used to identify specific flights and crewmembers. Such information, denoted sensitive information, includes flight data (here signifying data collected by sensors aboard an aircraft during flight), weather data for a specified route on a specified date, date and time, and any other information traceable to a specific flight. The removal of information that could be used to perform such tracing is called "deidentification." Airlines are often reluctant to keep flight data in identifiable form because of concerns about loss of anonymity. Hence, one of the things needed to promote retention and analysis of aviation data is an automated means of de-identification of archived flight data to enable integration of flight data with non-flight aviation data while preserving anonymity. Preferably, such an automated means would enable end users of the data to continue to use pre-existing data-analysis software to identify anomalies in flight data without identifying a specific anomalous flight. It would then also be possible to perform statistical analyses of integrated data. These needs are satisfied by the ADIS, which enables an end user to request aviation data associated with de-identified flight data. The ADIS

  7. Cathodal Transcranial Direct Current Stimulation Over Left Dorsolateral Prefrontal Cortex Area Promotes Implicit Motor Learning in a Golf Putting Task. (United States)

    Zhu, Frank F; Yeung, Andrew Y; Poolton, Jamie M; Lee, Tatia M C; Leung, Gilberto K K; Masters, Rich S W


    Implicit motor learning is characterized by low dependence on working memory and stable performance despite stress, fatigue, or multi-tasking. However, current paradigms for implicit motor learning are based on behavioral interventions that are often task-specific and limited when applied in practice. To investigate whether cathodal transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex (DLPFC) area during motor learning suppressed working memory activity and reduced explicit verbal-analytical involvement in movement control, thereby promoting implicit motor learning. Twenty-seven healthy individuals practiced a golf putting task during a Training Phase while receiving either real cathodal tDCS stimulation over the left DLPFC area or sham stimulation. Their performance was assessed during a Test phase on another day. Verbal working memory capacity was assessed before and after the Training Phase, and before the Test Phase. Compared to sham stimulation, real stimulation suppressed verbal working memory activity after the Training Phase, but enhanced golf putting performance during the Training Phase and the Test Phase, especially when participants were required to multi-task. Cathodal tDCS over the left DLPFC may foster implicit motor learning and performance in complex real-life motor tasks that occur during sports, surgery or motor rehabilitation.

    A core equation for estimation of fuel burn from path profile data was developed. This equation was used as a necessary ingredient in a dynamic program to define a fuel efficient flight path. The resultant algorithm is oriented toward use by general aviation. The pilot provides a description of the desired ground track, standard aircraft parameters, and weather at selected waypoints. The algorithm then derives the fuel efficient altitudes and velocities at the waypoints.

  14. Are inertial forces ever of significance in cricket, golf and other sports? (United States)

    Robinson, Garry; Robinson, Ian


    In previous papers we investigated the motion of a spherical projectile rotating about an arbitrary axis, subject to a drag force, a lift or Magnus force, and in the presence of a wind. The aim was to determine the motion of balls used in sporting games, primarily cricket. Newton’s laws of motion apply in an inertial (unaccelerated) coordinate system, but the rotating Earth is not an inertial system. In such a non-inertial system two additional forces are present, the Coriolis force which produces a side-ways movement, and the centrifugal force. Generally these two inertial forces produce noticeable effects only on the large scale, when either the time of travel and/or the path length is large. In this paper we have added both of these forces to the equations of motion. In addition, we have also included a ground friction force in order to simulate a ball rolling over a surface or, more generally, a body moving through a resistive medium such as water. Here we quantitatively investigate the magnitude and direction of the effect of the inertial forces in a number of cases. It is found that, as expected, the effects of the inertial forces are generally small for ball games. In cricket the side-ways movement is ≲1 cm for a throw from the boundary and ≲1 mm for a slow bowler’s delivery, and for a long drive in golf it is ≲10 cm. In lawn bowls the side-ways movement can be ∼2.8 cm, which may be significant, given the nature of this sport. The inertial forces are also potentially of relevance in sporting events not employing spherical projectiles. For example, in Olympic rowing we find that the side-ways movement can be more than 40 m for a 2 km race if it is not compensated for, and nearly 20 m for a 4 min mile event in athletics. The effect is also of significance in events such as swimming and horse racing. The importance of this is that athletes may not be aware of the effect and, in the case of rowing for example, may attribute it to side-ways currents

  15. A Review of General Aviation Safety (1984-2017). (United States)

    Boyd, Douglas D


    General aviation includes all civilian aviation apart from operations involving paid passenger transport. Unfortunately, this category of aviation holds a lackluster safety record, accounting for 94% of civil aviation fatalities. In 2014, of 1143 general aviation accidents, 20% were fatal compared with 0 of 29 airline mishaps in the United States. Herein, research findings over the past 30 yr will be reviewed. Accident risk factors (e.g., adverse weather, geographical region, post-impact fire, gender differences) will be discussed. The review will also summarize the development and implementation of stringent crashworthiness designs with multi-axis dynamic testing and head-injury protection and its impact on mitigating occupant injury severity. The benefits and drawbacks of new technology and human factor considerations associated with increased general aviation automation will be debated. Data on the safety of the aging general aviation population and increased drug usage will also be described. Finally, areas in which general aviation occupant survival could be improved and injury severity mitigated will be discussed with the view of equipping aircraft with 1) crash-resistant fuel tanks to reduce post-impact conflagration; 2) after-market ballistic parachutes for older aircraft; and 3) current generation electronic locator beacons to hasten site access by first responders.Boyd DD.

The status of flight tests and commercial operation were also introduced. Finally the problems for development and application of aviation biofuels were stated, and some accommodation were proposed.

  17. Global, regional and local health impacts of civil aviation emissions (United States)

    Yim, Steve H. L.; Lee, Gideon L.; Lee, In Hwan; Allroggen, Florian; Ashok, Akshay; Caiazzo, Fabio; Eastham, Sebastian D.; Malina, Robert; Barrett, Steven R. H.


    Aviation emissions impact surface air quality at multiple scales—from near-airport pollution peaks associated with airport landing and take off (LTO) emissions, to intercontinental pollution attributable to aircraft cruise emissions. Previous studies have quantified aviation’s air quality impacts around a specific airport, in a specific region, or at the global scale. However, no study has assessed the air quality and human health impacts of aviation, capturing effects on all aforementioned scales. This study uses a multi-scale modeling approach to quantify and monetize the air quality impact of civil aviation emissions, approximating effects of aircraft plume dynamics-related local dispersion (˜1 km), near-airport dispersion (˜10 km), regional (˜1000 km) and global (˜10 000 km) scale chemistry and transport. We use concentration-response functions to estimate premature deaths due to population exposure to aviation-attributable PM2.5 and ozone, finding that aviation emissions cause ˜16 000 (90% CI: 8300-24 000) premature deaths per year. Of these, LTO emissions contribute a quarter. Our estimate shows that premature deaths due to long-term exposure to aviation-attributable PM2.5 and O3 lead to costs of ˜21 bn per year. We compare these costs to other societal costs of aviation and find that they are on the same order of magnitude as global aviation-attributable climate costs, and one order of magnitude larger than aviation-attributable accident and noise costs.

  1. CAPPS II: the foundation of aviation security? (United States)

    Barnett, Arnold


    A new computer system is being developed to classify U.S. air travelers by the degree of terrorist threat they might pose. Reports indicate that the system--called CAPPS II--would use large amounts of information about each passenger, perhaps including such personal details as his or her magazine-subscription behavior. We argue that what is publicly known about CAPPS II raises questions about how substantially the system would improve aviation security. We discuss conditions under which CAPPS II could yield safety benefits, but suggest that it might be more prudent to view the system as one component of future security arrangements rather than the centerpiece of these arrangements.

    Harvey, T.


    In this paper, a review of the background and some drivers are provided for X-ray screening for aviation security. Some of the key considerations are highlighted along with impacts of the image-based approaches and signature approaches. The role of information theory is discussed along with some recent work that may influence the technical direction by posing the question: "what measurements, parameters and metrics should be considered in future system design?" A path forward should be based on information theory, however electronic machines will likely interface with humans and be dollar-cost driven, so ultimately solutions must consider additional parameters other than only technical performance factors.

    Schafrik, Robert E.


    The threat posed to commercial aviation by small, concealed plastic explosives is particularly onerous. Small amounts of these highly energetic explosives are difficult to reliably detect using current technologies. But they can cause significant damage to an aircraft that can result in the destruction of the aircraft, resulting in loss of life. The key issues regarding explosive detection technologies include: What methods can detect plastic explosives? How do these methods perform in practice? How can the different methods be best employed to counter the terrorist threat?

  10. Design of a Golf Swing Injury Detection and Evaluation open service platform with Ontology-oriented clustering case-based reasoning mechanism. (United States)

    Ku, Hao-Hsiang


    Nowadays, people can easily use a smartphone to get wanted information and requested services. Hence, this study designs and proposes a Golf Swing Injury Detection and Evaluation open service platform with Ontology-oritened clustering case-based reasoning mechanism, which is called GoSIDE, based on Arduino and Open Service Gateway initative (OSGi). GoSIDE is a three-tier architecture, which is composed of Mobile Users, Application Servers and a Cloud-based Digital Convergence Server. A mobile user is with a smartphone and Kinect sensors to detect the user's Golf swing actions and to interact with iDTV. An application server is with Intelligent Golf Swing Posture Analysis Model (iGoSPAM) to check a user's Golf swing actions and to alter this user when he is with error actions. Cloud-based Digital Convergence Server is with Ontology-oriented Clustering Case-based Reasoning (CBR) for Quality of Experiences (OCC4QoE), which is designed to provide QoE services by QoE-based Ontology strategies, rules and events for this user. Furthermore, GoSIDE will automatically trigger OCC4QoE and deliver popular rules for a new user. Experiment results illustrate that GoSIDE can provide appropriate detections for Golfers. Finally, GoSIDE can be a reference model for researchers and engineers.

    Full Text Available Poland, as a member of the EU, is represented within the ICAO, by the European Aviation Safety Agency. However, this does not relieve our country from the responsibility of developing a state safety programme (SSP. The need to set up such a programme, which has to be specific to every country involved in aviation operation, was introduced by the ICAO’s Annex 19. One of the important points in Annex 19 is: “5.2.1 Each State shall establish and maintain a safety database to facilitate the effective analysis of information on actual or potential safety deficiencies obtained, including that from its incident reporting systems, and to determine any actions required for the enhancement of safety”. The Polish Civil Aviation Authority, along with other databases, manages the European Coordination Centre for Aviation Incident Reporting Systems (ECCAIRS. The authors (who are specialists dealing with exploitation processes in aviation have conducted a laborious processing of the data contained in the ECCAIRS database, analysing them based on various criteria: aviation occurrence categories (as defined by the ICAO, phases of flight for different airports in Poland etc. Aircraft with an maximum take-off mass (MTOM 5,700 kg (commercial aviation were considered separately. It was found that the most events are those that relate to power plant (SCF-PP airframes and related system (SCF-NP failures, followed by collisions with birds (BIRD, events related to airports (ADRM and events related to the required separation of aircraft (MAC. For lighter aircraft, the dominant categories are ARC, CTOL, GTOW and LOC-I events. The article presents a proposed method for predicting the number of events, determining the alert levels for the next years and assuming a normal distribution (Gaussian. It is one of the first attempts to use actual data contained in the database of events on airports in Poland. The results of this analysis may support the decisions of

  18. Faith based aviation: An ethnographic study of missionary flights international (United States)

    Cooper, Joseph H.

    The development of faith-based missionary aviation is a post-World War II phenomenon. The war effort demonstrated the value, utility, and global reach of aviation to remote, underdeveloped areas of the world. With the beginnings of a worldwide infrastructure for aviation, Christian aviators realized aviation could increase the range and effectiveness of their efforts to reach the world for Christ (Mellis, 2006). Although individual organizations provide statistical information and data about flight operations there is a lack of external evidence and relevant research literature confirming the scope and value of these faith based aviation organizations and operations. A qualitative, ethnographic study was conducted to document the activities of one faith-based aviation organization to gain an understanding of this little known aspect of civilian aviation. The study was conducted with Missionary Flights International (MFI) of Fort Pierce, FL which has been involved in faith-based, missionary aviation since its inception in 1964. As an aviation organization "MFI strives to offer affiliated missions the kind of efficient service and professionalism expected of an airline operation" (Missionary Flights International, 2013, p.1). MFI is a lifeline for missionaries to Haiti and the Dominican Republic, fulfilling their motto of "Standing in the Gap". MFI provides twice a week service to the island of Hispaniola and the Republic of Haiti. In this in-depth study insight and understanding was gained into the purpose of MFI, their daily routines and operations, and the challenges they face in maintaining their flight services to Haiti. This study provided documentation of the value and utility of such aviation efforts and of the individuals involved in this endeavor.

  20. Psychophysiological and other factors affecting human performance in accident prevention and investigation. [Comparison of aviation with other industries

    Energy Technology Data Exchange (ETDEWEB)

    Klinestiver, L.R.


    Psychophysiological factors are not uncommon terms in the aviation incident/accident investigation sequence where human error is involved. It is highly suspect that the same psychophysiological factors may also exist in the industrial arena where operator personnel function; but, there is little evidence in literature indicating how management and subordinates cope with these factors to prevent or reduce accidents. It is apparent that human factors psychophysological training is quite evident in the aviation industry. However, while the industrial arena appears to analyze psychophysiological factors in accident investigations, there is little evidence that established training programs exist for supervisors and operator personnel.

  1. Analysis of Aviation Safety Reporting System Incident Data Associated With the Technical Challenges of the Vehicle Systems Safety Technology Project (United States)

    Withrow, Colleen A.; Reveley, Mary S.


    This analysis was conducted to support the Vehicle Systems Safety Technology (VSST) Project of the Aviation Safety Program (AVsP) milestone VSST4.2.1.01, "Identification of VSST-Related Trends." In particular, this is a review of incident data from the NASA Aviation Safety Reporting System (ASRS). The following three VSST-related technical challenges (TCs) were the focus of the incidents searched in the ASRS database: (1) Vechicle health assurance, (2) Effective crew-system interactions and decisions in all conditions; and (3) Aircraft loss of control prevention, mitigation, and recovery.

  2. Prevalence of drugs and alcohol in fatal civil aviation accidents between 1994 and 1998. (United States)

    Canfield, D V; Hordinsky, J; Millett, D P; Endecott, B; Smith, D


    The use of drugs and alcohol in aviation is closely monitored by the FAA Office of Aviation Medicine's (OAM's) Civil Aeromedical Institute (CAMI) through the toxicological analysis of specimens from pilots who have died in aviation accidents. Frozen specimens received from local pathologists were tested and the results entered into a computer database for future analysis. The data were sorted based on the class of drug, controlled dangerous substance schedules II, and I controlled dangerous substance schedules III-V, prescription drugs, over-the-counter drugs, and alcohol. Specimens from 1683 pilots were analyzed between 1994 to 1998. Controlled dangerous substances, CDS, (schedules I and II) were found in 89 of the pilots analyzed. Controlled dangerous substances (schedules III-V) were found in 49 of the pilots tested. Prescription drugs were found in 240 of the pilots analyzed. Over-the-counter drugs were found in 301 of the pilots analyzed. Alcohol at or above the legal limit of 0.04% was found in 124 pilots. No abused drugs were found in Class 1 air transport fatal pilots. This research supports the very low incidence rate of drugs found in the FAA random drug-testing program. Over-the-counter medications are the most frequently found drugs in fatal aviation accidents and many of these drugs could impair a pilot's ability to safely fly an aircraft. This data is helpful to the FAA in developing programs to reduce the usage of dangerous drugs and identify potentially incapacitating medical conditions that may cause an accident. Data collected from this research can be used to evaluate the effectiveness of the FAA drug-testing program.

  3. Russian eruption warning systems for aviation (United States)

    Neal, C.; Girina, O.; Senyukov, S.; Rybin, A.; Osiensky, J.; Izbekov, P.; Ferguson, G.


    More than 65 potentially active volcanoes on the Kamchatka Peninsula and the Kurile Islands pose a substantial threat to aircraft on the Northern Pacific (NOPAC), Russian Trans-East (RTE), and Pacific Organized Track System (PACOTS) air routes. The Kamchatka Volcanic Eruption Response Team (KVERT) monitors and reports on volcanic hazards to aviation for Kamchatka and the north Kuriles. KVERT scientists utilize real-time seismic data, daily satellite views of the region, real-time video, and pilot and field reports of activity to track and alert the aviation industry of hazardous activity. Most Kurile Island volcanoes are monitored by the Sakhalin Volcanic Eruption Response Team (SVERT) based in Yuzhno-Sakhalinsk. SVERT uses daily moderate resolution imaging spectroradiometer (MODIS) satellite images to look for volcanic activity along this 1,250-km chain of islands. Neither operation is staffed 24 h per day. In addition, the vast majority of Russian volcanoes are not monitored seismically in real-time. Other challenges include multiple time-zones and language differences that hamper communication among volcanologists and meteorologists in the US, Japan, and Russia who share the responsibility to issue official warnings. Rapid, consistent verification of explosive eruptions and determination of cloud heights remain significant technical challenges. Despite these difficulties, in more than a decade of frequent eruptive activity in Kamchatka and the northern Kuriles, no damaging encounters with volcanic ash from Russian eruptions have been recorded. ??

  9. The Aviation System Monitoring and Modeling (ASMM) Project: A Documentation of its History and Accomplishments: 1999-2005 (United States)

    Statler, Irving C. (Editor)


    The Aviation System Monitoring and Modeling (ASMM) Project was one of the projects within NASA s Aviation Safety Program from 1999 through 2005. The objective of the ASMM Project was to develop the technologies to enable the aviation industry to undertake a proactive approach to the management of its system-wide safety risks. The ASMM Project entailed four interdependent elements: (1) Data Analysis Tools Development - develop tools to convert numerical and textual data into information; (2) Intramural Monitoring - test and evaluate the data analysis tools in operational environments; (3) Extramural Monitoring - gain insight into the aviation system performance by surveying its front-line operators; and (4) Modeling and Simulations - provide reliable predictions of the system-wide hazards, their causal factors, and their operational risks that may result from the introduction of new technologies, new procedures, or new operational concepts. This report is a documentation of the history of this highly successful project and of its many accomplishments and contributions to improved safety of the aviation system.
