    Full Text Available Background: Athletes focus their training on two major goals, i.e., avoidance of the injury and increasing the performance. Balance training has been widely used in competitive sports to improve the balance and thus reduce the risk of injury, for example, ligamentous sprains, which are very common in Basketball. On the other hand, various drills are being used to improve the performance parameters such as agility. Our effort is to find out an exercise program which focuses on balance training and see whether it has any effect on agility. Methods: The study design was a Pretest-Posttest Control-Group Design. 30 healthy school level Male Basketball Players were selected from V-One Basketball Academy, Don Bosco Basketball Academy, Modern School Basketball Academy, New Delhi. They were randomly divided into two groups. Group A performed dynamic balance training 3 sessions per week for 4 weeks. Group B performed conventional exercises throughout the duration of the study. Outcome measure, i.e., T- test was measured pre and post 4 week period. Results: Data analysis was done by Independent t test and Paired t test for between group analysis and within group analysis respectively. There was a significant reduction in T-test times in the experimental group as compared to the control group (‘p’ value <0.05 while there was no significant improvement in the control group. Conclusion: Four weeks of dynamic balance training significantly improved agility as detected by T-test. Thus it can be concluded that the used protocol can be incorporated in the training regimes to reduce the risk of injury as well as improve the performance.

    The quick change of direction (i.e., agility) is an important athletic ability in numerous sports. Because of the diverse and therefore hardly predictable manifestations of agility in sports, studies noted that the improvement in speed, power, and balance should result in an improvement of agility. However, there is evident lack of data regarding the influence of potential predictors on different agility manifestations. The aim of this study was to determine the gender-specific influence of speed, power, and balance on different agility tests. A total of 32 college-aged male athletes and 31 college-aged female athletes (age 20.02 ± 1.89 years) participated in this study. The subjects were mostly involved in team sports (soccer, team handball, basketball, and volleyball; 80% of men, and 75% of women), martial arts, gymnastics, and dance. Anthropometric variables consisted of body height, body weight, and the body mass index. Five agility tests were used: a t-test (T-TEST), zig-zag test, 20-yard shuttle test, agility test with a 180-degree turn, and forward-backward running agility test (FWDBWD). Other tests included 1 jumping ability power test (squat jump, SQJ), 2 balance tests to determine the overall stability index and an overall limit of stability score (both measured by Biodex Balance System), and 2 running speed tests using a straight sprint for 10 and 20 m (S10 and S20, respectively). A reliability analysis showed that all the agility tests were reliable. Multiple regression and correlation analysis found speed and power (among women), and balance (among men), as most significant predictors of agility. The highest Pearson's correlation in both genders is found between the results of the FWDBWD and S10M tests (0.77 and 0.81 for men and women, respectively; p agility performance for men but not for women. In addition to demonstrating a known relationship between speed and agility in both genders, and a small but statistically significant relationship between

    The purpose of this study was to determine the efficacy of a home-based kinesthesia, balance and agility (KBA) exercise program to improve symptoms among persons age ≥ 50 years with knee osteoarthritis (OA). Forty-four persons were randomly assigned to 8-weeks, 3 times per week KBA, resistance training (RT), KBA + RT, or Control. KBA utilized walking agility exercises and single-leg static and dynamic balancing. RT used elastic resistance bands for open chain lower extremity exercises. KBA + RT performed selected exercises from each technique. Control applied inert lotion daily. Outcomes included the OA specific WOMAC Index of Pain, Stiffness, and Physical Function (PF), community activity level, exercise self-efficacy, self-report knee stability, and 15m get up & go walk (GUG). Thirty-three participants [70.7 (SD 8.5) years] completed the trial. Analysis of variance comparing baseline, mid-point, and follow-up measures revealed significant (p self-efficacy. Knee stability was improved in RT and Control. GUG improved in RT and KBA+RT. These results indicate that KBA, RT, or a combination of the two administered as home exercise programs are effective in improving symptoms and quality of life among persons with knee OA. Control results indicate a strong placebo effect in the short term. A combination of KBA and RT should be considered as part of the rehabilitation program, but KBA or RT alone may be appropriate for some patients. Studies with more statistical power are needed to confirm or refute these results. Patient presentation, preferences, costs, and convenience should be considered when choosing an exercise rehabilitation approach for persons with knee OA.

    The aim of this paper was to examine the effects of training using Xbox Kinect on agility and balance in healthy young adults. Forty-three healthy adults (aged 20 to 30 years) were randomized to either an intervention or control group. The intervention group played Xbox Kinect 3 times per week, for an average of 20 minutes per session for 6 weeks. The control group did not play Xbox Kinect. All the participants completed assessments of agility and balance at baseline, 2, 4, and 6 weeks. After 6 weeks of training the intervention group showed significant improvement in agility at 2 weeks and showed continued improvement at 4 and 6 weeks (Pagility and dynamic balance in the medial and posterior directions in healthy young adults.

    Full Text Available Objective: The purpose of this investigation was to determine the differences in collegiate and recreationally trained soccer players in sprint, vertical jump, and balance performance. Methods: Twenty-one soccer players, twelve Division II collegiate and nine recreationally trained volunteered to participate. Session one acted as a familiarization day, where the participants were familiarized with testing day protocols. During testing day, participants performed a dynamic warm-up, followed by balance measurements, three countermovement vertical jumps, and pro-agility shuttle test. Results: There were no significant (p>0.05 differences between groups in the all balance variables. Collegiate soccer players had a significantly (p0.05 differences in groups in all other variables. Conclusion: These results indicate that collegiate, Division II, soccer players had greater vertical jumping and sprinting velocities when compared to recreationally trained soccer players. These results may have been impacted by the lack of resistance training background in either of the two groups. With the addition of more time on a collegiate resistance training program, it is very likely the Division II athletes will see a significant increase in all balance, sprint, and vertical jump performance measures compared to recreationally trained players who receive little to no specialized resistance training.

    The purpose of this study was to compare the acute effects of three different stretching protocols on balance, agility, reaction time and movement time of the upper limbs. Participants were thirty one female high school athletes (age = 17.3 ± 0.5 yr.). All participants performed one of the following protocols on different days: (a) 3 min jogging followed by 7 min static stretching (SS), (b) 3 min jogging followed by 7 min dynamic stretching (DS), and (c) 3 min jogging followed by 7 min of rest (NS). After the protocols participants performed the following tests: dynamic balance, 505 agility test, reaction time (time between a sound stimulus and release of a button) and movement time (movement of the upper extremity over a 0.5 m distance). The order of stretching protocols and performance tests were counterbalanced to avoid carryover effects. Repeated measures analysis of variance revealed significant main effects for all variables except reaction time. The DS protocol compared to SS performed significantly better in balance, agility and movement time. Additionally, the DS protocol compared to NS performed significantly better in agility. According to the results of the study, a DS protocol is more appropriate than SS for activities that require balance, rapid change of running direction (agility) and movement time of the upper extremities. Key pointsStatic stretching has a negative effect on balance and agility performance compared to dynamic stretching.There was no effect of the stretching protocols on reaction time.Dynamic stretching was more effective than static stretching for increasing movement time of the upper extremities.

    Ankle stabilizers can reduce ankle sprain incidence and severity by limiting range of motion. Still whether using them affects performance remains unclear. The authors compared effects of 3 ankle stabilizers, tape, lace-up (Swede-O Ankle Lok), and semirigid (Air-Cast Air-Stirrup) braces, and a nonsupport control on vertical jump (Sargent Jump Test), agility (Right-Boomerang Run test), and dynamic balance (Modified Bass Test) in 10 volunteers (4 males, 6 females; 25.6 ± 2.8 years, 167.8 ± 13.7 cm, 61.4 ± 10.7 kg) using repeated-measures ANOVAs. Participants had similar vertical jump (P = .27; control = 41.40 ± 11.89 cm, tape = 37.90 ± 7.92 cm, Swede-O = 41.40 ± 11.89 cm, Air-Cast = 39.29 ± 10.85 cm) and dynamic balance (P = .08; control = 92.50 ± 2.46, tape = 91.55 ± 3.53, Swede-O = 97.00 ± 5.32, Air-Cast = 89.40 ± 6.08) but differing agility scores (P = .03; control = 13.55 ± 1.35 seconds, tape = 14.03 ± 1.5 seconds, Swede-O = 14.10 ± 1.36 seconds, Air-Cast = 14.14 ± 1.41 seconds). Post hoc tests revealed a significant difference (P = .03) between control and Air-Cast but not between Swede-O (P = .06) or tape (P = .07). Effect size (d) analyses indicated that compared with control, all stabilizers trended to increase agility run times (tape, d = 0.33; Swede-O, d = 0.40; Air-Cast, d = 0.43). Since participants primarily required sagittal plane motion when jumping vertically and had relatively slow directional changes in the dynamic balance test, wearing ankle stabilizers did not hamper jump or balance. However, ankle stabilizers hindered participants' ability to perform quick directional changes required in the agility test, with the most rigid stabilizer (Air-Cast) affecting agility the most. Clinicians should be aware that ankle stabilizers may affect some performance measures (agility) but not others (jumping, balance) and continue examinations in larger cohorts. Therapeutic, Level II.

    Research and development in the design and manufacture of Microelectromechanical Systems (MEMS) is growing at an enormous rate. Advances in MEMS design tools and fabrication processes at Sandia National Laboratories` Microelectronics Development Laboratory (MDL) have broadened the scope of MEMS applications that can be designed and manufactured for both military and commercial use. As improvements in micromachining fabrication technologies continue to be made, MEMS designs can become more complex, thus opening the door to an even broader set of MEMS applications. In an effort to further research and development in MEMS design, fabrication, and application, Sandia National Laboratories has launched the Sandia Agile MEMS Prototyping, Layout Tools, Education and Services Program or SAMPLES program. The SAMPLES program offers potential partners interested in MEMS the opportunity to prototype an idea and produce hardware that can be used to sell a concept. The SAMPLES program provides education and training on Sandia`s design tools, analysis tools and fabrication process. New designers can participate in the SAMPLES program and design MEMS devices using Sandia`s design and analysis tools. As part of the SAMPLES program, participants` designs are fabricated using Sandia`s 4 level polycrystalline silicon surface micromachine technology fabrication process known as SUMMiT (Sandia Ultra-planar, Multi-level MEMS Technology). Furthermore, SAMPLES participants can also opt to obtain state of the art, post-fabrication services provided at Sandia such as release, packaging, reliability characterization, and failure analysis. This paper discusses the components of the SAMPLES program.

    The aim of the present study was to investigate the effects of a short-term in-season plyometric training program on power, agility and knee extensor strength. Male soccer players from a third league team were assigned into an experimental and a control group. The experimental group, beside its regular soccer training sessions, performed a periodized plyometric training program for six weeks. The program included two training sessions per week, and maximal intensity unilateral and bilateral plyometric exercises (total of 40 - 100 foot contacts/session) were executed. Controls participated only in the same soccer training routine, and did not perform plyometrics. Depth vertical jump height, agility (Illinois Agility Test, T Agility Test) and maximal voluntary isometric torque in knee extensors using Multicont II dynamometer were evaluated before and after the experiment. In the experimental group small but significant improvements were found in both agility tests, while depth jump height and isometric torque increments were greater. The control group did not improve in any of the measures. Results of the study indicate that plyometric training consisting of high impact unilateral and bilateral exercises induced remarkable improvements in lower extremity power and maximal knee extensor strength, and smaller improvements in soccer-specific agility. Therefore, it is concluded that short-term plyometric training should be incorporated in the in-season preparation of lower level players to improve specific performance in soccer.

    We performed a systematic review and evaluation of the existing scientific literature on the association between flexibility, power, speed, balance, and agility, and musculoskeletal injury (MSK-I) risk in military and civilian populations. MEDLINE, EBSCO, EMBASE, and the Defense Technical Information Center were searched for original studies published from 1970 through 2015 that examined associations between these physical fitness measures (flexibility, power, speed, balance, and agility) and MSK-I. Methodological quality and strength of the evidence were determined following criteria adapted from previously published systematic reviews. Twenty-seven of 4,229 citations met our inclusion criteria. Primary findings indicate there is (a) moderate evidence that hamstring flexibility, as measured by performance on a sit-and-reach test or active straight-leg raise test assessed with goniometry, and ankle flexibility, assessed with goniometry, are associated with MSK-I risk; (b) moderate evidence that lower body power, as measured by performance on a standing broad jump or vertical jump with no countermovement, is associated with MSK-I risk; (c) moderate evidence that slow sprint speed is associated with MSK-I risk; (d) moderate evidence that poor performance on a single-leg balance test is associated with increased risk for ankle sprain; and (e) insufficient evidence that agility is associated with MSK-I risk. Several measures of flexibility, power, speed, and balance are risk factors for training-related MSK-I in military and civilian athletic populations. Importantly, these findings can be useful for military, first responder, and athletic communities who are seeking evidence-based metrics for assessing or stratifying populations for risk of MSK-I.

    of the problems of DSD. However important incompatibilities between the challenges of DSD and the key tenets of agility exist and achieving a beneficially balanced agile practice in DSD can be difficult. Trust could be the key to this, since trust is crucial for the necessary corporate behavior that leads to team...... success. This article reports from a study of two agile DSD teams with very different organization and collaboration patterns. It addresses the role of trust and distrust in DSD by analyzing how the team members’ trust developed and erode through the lifetime of the two collaborations and how management...... actions influenced this. We see two important lessons from the analysis. First the agile practices of daily Scrum and self organizing team can empower DSD teams to manage their own development of trust and thereby alleviate the obstacles of DSD. Second if management fails to support the development...

    Informed decision making is a critical activity in software development but it is poorly supported by common development environments which focus mainly on low level programming tasks. We posit the need for agile software assessment which aims to support decision making by enabling rapid and effective construction of software models and custom analyses. Agile software assessment entails gathering and exploiting the broader context of software information related to the system at hand as well ...

    Children with Developmental Coordination Disorder (DCD) are physically less active, preferring more sedentary behavior and are at risk of developing health problems or becoming overweight. 18 children (age 6-10years) with lower levels of motor coordination attending a primary school in a low-income community in South Africa (score on Movement Assessment Battery for Children Second edition equal to or below the 5th percentile) were selected to participate in the study and were age-matched with typically developing peers (TD). Both groups of children engaged in 20min of active Nintendo Wii Fit gaming on the balance board, twice a week for a period of five weeks. All children were tested before and after the intervention using the lower limb items of the Functional Strength Measurement, the 5×10 meter sprint test, the 5×10 meter slalom sprint test, and the Balance, Running speed and Agility subtest of the Bruininks Oseretsky Test of Motor Proficiency 2nd edition (BOT-2). After intervention, both groups of children improved in functional strength and anaerobic fitness. The magnitude of these changes was not related to participant's motor coordination level. However, differences in change between the TD and DCD group were apparent on the motor performance tests; children with DCD seemed to benefit more in balance skills of the BOT-2, while the TD children improved more in the Running speed and Agility component of the BOT-2. Compliance to the study protocol over 5weeks was high and the effect on physical functioning was shown on standardized measures of physical performance validated for children with and without DCD.

    Full Text Available Falls are a serious problem for the elderly because the high rate of mortality and morbidity. The risk factors related to falls are many and it is difficult to isolate the triggering elements. Deficits in balance, problems of sight, decreases of strength in the legs, loss of coordination and changes in propioception are important factors. It is necessary to have simple assessment field tests to detect problems which lead to falls. A group of subjects (n=33, mean age 70,2 + 5,3, and a physical activity profile of at least two days a week, who walked between 35 and 90 minutes as and average, 4 days a week, answered a personal data questionnaire and provided data on falls. The results showed that bipodal standing with open eyes tests were not discriminatory. Significant positive correlations were found between items of static balance test (0,31 < r < 0,71 and the probability limits of 0,001< p < 0,05. It is recommended to include the agility test in assessment.

  14. Effects of over-the-counter jaw-repositioning mouth guards on dynamic balance, flexibility, agility, strength, and power in college-aged male athletes.

    Science.gov (United States)

    Golem, Devon L; Arent, Shawn M

    2015-02-01

    Improvements in muscular power and anaerobic performance have resulted from the use of jaw-repositioning mouth guards designed with advanced dental techniques. The high cost of such techniques has dissuaded the widespread use. Recently, more affordable, over-the-counter (OTC) jaw-repositioning mouth guards have become available. The primary objective of this study was to examine the effects of 2 OTC jaw-repositioning mouth guards on muscular power and strength performance in college-aged male athletes. It was hypothesized that similar to previous observations with advanced dentistry-designed mouth guards, OTC jaw-repositioning mouth guards would impart positive effects on muscular power but not have any effect on muscular strength. Secondary objectives of this study included the examination of the effects of 2 OTC jaw-repositioning mouth guards on other variables related to athletic performance. Male collegiate athletes (N = 20) participated in 4 separate testing sessions that consisted of assessment of muscular power, dynamic balance, flexibility, agility, and muscular strength. The 4 conditions, 1 per testing session, were assigned in a randomized order and consisted of a no-mouth guard control (CON), a placebo mouth guard, a self-adapted jaw-repositioning mouth guard (SA), and a custom-fitted jaw-repositioning mouth guard (CF). No significant differences were observed between conditions in muscular power (p = 0.78), dynamic balance (p = 0.99), agility (p = 0.22), or muscular strength (p = 0.47). The CF had significantly lower hip flexion than the CON (p = 0.014) and had significantly greater lumbar spine lateral flexion compared with the SA condition (p = 0.054). However, these flexibility differences lack practical relevance as the effect sizes remain very small (ES = -0.27 and -0.14, respectively). In conclusion, the jaw-repositioning technique used in the design of these OTC mouth guards did not affect performance. It is important to note that negative

    Lampa, Samuel; Alvarsson, Jonathan; Spjuth, Ola

    2016-01-01

    Predictive modelling in drug discovery is challenging to automate as it often contains multiple analysis steps and might involve cross-validation and parameter tuning that create complex dependencies between tasks. With large-scale data or when using computationally demanding modelling methods, e-infrastructures such as high-performance or cloud computing are required, adding to the existing challenges of fault-tolerant automation. Workflow management systems can aid in many of these challenges, but the currently available systems are lacking in the functionality needed to enable agile and flexible predictive modelling. We here present an approach inspired by elements of the flow-based programming paradigm, implemented as an extension of the Luigi system which we name SciLuigi. We also discuss the experiences from using the approach when modelling a large set of biochemical interactions using a shared computer cluster.Graphical abstract.

    The purpose of this study was to determine the effects of a 12-week contrast training (CT) program (isometric + plyometric), with no external loads, on the vertical jump, kicking speed, sprinting, and agility skills of young soccer players. Thirty young soccer players (age, 15.9 ± 1.43 years; weight, 65.4 ± 10.84 kg; height, 171.0 ± 0.06 cm) were randomized in a control group (n = 13) and an experimental group (n = 17). The CT program was included in the experimental group's training sessions, who undertook it twice a week as a part of their usual weekly training regime. This program included 3 exercises: 1 isometric and 2 plyometric, without external loads. These exercises progressed in volume throughout the training program. Performance in countermovement jump (CMJ), Balsom agility test (BAT), 5-, 10-, 20-, and 30-m sprint, and soccer kick were assessed before and after the training program. A 2-factor (group and time) analysis of variance revealed significant improvements (p external loads is effective for improving soccer-specific skills such as vertical jump, sprint, agility, and kicking speed in young soccer players.

    An important measure of a signed graph is the line index of balance which has several applications in many fields. However, this graph-theoretic measure was underused for decades because of the inherent complexity in its computation which is closely related to solving NP-hard graph optimisation problems like MAXCUT. We develop new quadratic and linear programming models to compute the line index of balance exactly. Using the Gurobi integer programming optimisation solver, we evaluate the line...

    Full Text Available Impaired balance has been associated with an increased risk for falls and a resulting increase in the mortality rate of elder people. Thus, balance-training interventions have an important place in fall prevention. This study was designed with the purpose of identifying the appropriate balance-training program for community dwelling elderly adults with an active lifestyle. A sample of 70 elderly adults were randomly allocated into two groups: group 1 (n=35 received general balance and mobility exercise; group 2 (n=35 received specific balance strategy training. The intervention consisted of 5 sessions/week for 4 weeks. The outcome measures were Timed up and go test (TUGT and Berg balance scale (BBS. An inter-group (2-way mixed model analysis of co-variance and intra-group (repeated measures analysis was done to find the change in balance scores. After the intervention, the TUGT scores in group 1 were, mean=10.38 s, standard deviation (SD=1.59 s and in group 2 were, mean=9.27 s, SD=1.13 s. Post training, BBS scores for group 1 were, mean=54.69, SD=1.13, and for group 2 were, mean=55.57, SD =0.56. There was a significant group × time effect for TUGT and BBS score. All the subjects showed significant changes in balance scores after balance training interventions. The subjects who participated in the specific balance-strategy training significantly improved their functional mobility, as shown on the TUGT, compared to the general training group.

    Full Text Available Today agile approaches are often used for the development of digital products. Since their development in the 90s, Agile Methodologies, such as Scrum and Extreme Programming, have evolved. Team collaboration is strongly influenced by the values and principles of the Agile Manifesto. The values and principles described in the Agile Manifesto support the optimization of the development process. In this article, the current operation is analyzed in Agile Product Development Processes. Both, the cooperation in the project team and the understanding of the roles and tasks will be analyzed. The results are set in relation to the best practices of Agile Methodologies. A quantitative questionnaire related to best practices in Agile Product Development was developed. The study was carried out with 175 interdisciplinary participants from the IT industry. For the evaluation of the results, 93 participants were included who have expertise in the subject area Agile Methodologies. On one hand, it is shown that the collaborative development of product-related ideas brings benefits. On the other hand, it is investigated which effect a good understanding of the product has on decisions made during the implementation. Furthermore, the skillset of product managers, the use of pair programming, and the advantages of cross-functional teams are analyzed.

    We describe experiences applying agile software development techniques to the realm of data management during the development of the Global Change Information System (GCIS), a web service and API for authoritative global change information under development by the US Global Change Research Program. Some of the challenges during system design and implementation have been : (1) balancing the need for a rigorous mechanism for ensuring information quality with the realities of large data sets whose contents are often in flux, (2) utilizing existing data to inform decisions about the scope and nature of new data, and (3) continuously incorporating new knowledge and concepts into a relational data model. The workflow for managing the content of the system has much in common with the development of the system itself. We examine various aspects of agile software development and discuss whether or how we have been able to use them for data curation as well as software development.

    The objective of agile manufacturing is to provide the ability to quickly realize high-quality, highly-customized, in-demand products at a cost commensurate with mass production. More broadly, agility in manufacturing, or any other endeavor, is defined as change-proficiency; the ability to thrive in an environment of unpredictable change. This report discusses the general direction of the agile manufacturing initiative, including research programs at the National Institute of Standards and Technology (NIST), the Department of Energy, and other government agencies, but focuses on agile manufacturing from a statistical perspective. The role of statistics can be important because agile manufacturing requires the collection and communication of process characterization and capability information, much of which will be data-based. The statistical community should initiate collaborative work in this important area.

    2015-12-01

    The growing volume, variety and velocity of production of Earth science data magnifies the impact of inefficiencies in data acquisition, processing, analysis, and sharing workflows, potentially to the point of impairing the ability of researchers to accomplish their desired scientific objectives. The adaptation of agile software development principles (http://agilemanifesto.org/principles.html) to data curation processes has significant potential to lower barriers to effective scientific data discovery and reuse - barriers that otherwise may force the development of new data to replace existing but unusable data, or require substantial effort to make data usable in new research contexts. This paper outlines a data curation process that was developed at the University of New Mexico that provides a cross-walk of data and associated documentation between the data archive developed by the Long Term Ecological Research (LTER) Network Office (PASTA - http://lno.lternet.edu/content/network-information-system) and UNM's institutional repository (LoboVault - http://repository.unm.edu). The developed automated workflow enables the replication of versioned data objects and their associated standards-based metadata between the LTER system and LoboVault - providing long-term preservation for those data/metadata packages within LoboVault while maintaining the value-added services that the PASTA platform provides. The relative ease with which this workflow was developed is a product of the capabilities independently developed on both platforms - including the simplicity of providing a well-documented application programming interface (API) for each platform enabling scripted interaction and the use of well-established documentation standards (EML in the case of PASTA, Dublin Core in the case of LoboVault) by both systems. These system characteristics, when combined with an iterative process of interaction between the Data Curation Librarian (on the LoboVault side of the process

    The purpose of this study was to evaluate the effects of 6 months of specific balance training included in endurance-resistance program on postural balance in haemodialysis (HD) patients. Forty-nine male patients undergoing HD were randomly assigned to an intervention group (balance training included in an endurance-resistance training, n = 26) or a control group (resistance-endurance training only, n = 23). Postural control was assessed using six clinical tests; Timed Up and Go test, Tinetti Mobility Test, Berg Balance Scale, Unipodal Stance test, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scale. All balance measures increased significantly after the period of rehabilitation training in the intervention group. Only the Timed Up and Go, Berg Balance Scale, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scores were improved in the control group. The ranges of change in these tests were greater in the balance training group. In HD patients, specific balance training included in a usual endurance-resistance training program improves static and dynamic balance better than endurance-resistance training only. Implications for rehabilitation Rehabilitation using exercise in haemodialysis patients improved global mobility and functional abilities. Specific balance training included in usual endurance resistance training program could lead to improved static and dynamic balance.

    Abstract It has become almost routine practice to incorporate balance exercises into training programs for athletes from different sports. However, the type of training that is most efficient remains unclear, as well as the frequency, intensity and duration of the exercise that would be most beneficial have not yet been determined. The following review is based on papers that were found through computerized searches of PubMed and SportDiscus from 2000 to 2016. Articles related to balance training, testing, and injury prevention in young healthy athletes were considered. Based on a Boolean search strategy the independent researchers performed a literature review. A total of 2395 articles were evaluated, yet only 50 studies met the inclusion criteria. In most of the reviewed articles, balance training has proven to be an effective tool for the improvement of postural control. It is difficult to establish one model of training that would be appropriate for each sport discipline, including its characteristics and demands. The main aim of this review was to identify a training protocol based on most commonly used interventions that led to improvements in balance. Our choice was specifically established on the assessment of the effects of balance training on postural control and injury prevention as well as balance training methods. The analyses including papers in which training protocols demonstrated positive effects on balance performance suggest that an efficient training protocol should last for 8 weeks, with a frequency of two training sessions per week, and a single training session of 45 min. This standard was established based on 36 reviewed studies. PMID:28828077

    The prevalence of overweight and obesity in most developed countries has markedly increased during the last decades. In addition to genetic, hormonal, and metabolic influences, environmental factors like fetal and neonatal nutrition play key roles in the development of obesity. Interestingly, overweight during critical developmental periods of fetal and/or neonatal life has been demonstrated to increase the risk of obesity throughout juvenile life into adulthood. In spite of this evidence, the specific mechanisms underlying this fetal/neonatal programming are not perfectly understood. However, it is clear that circulating hormones such as insulin and leptin play a critical role in the development and programming of hypothalamic circuits regulating energy balance. Here, we review what is currently known about the impact of perinatal malnutrition on the mechanisms regulating body weight homeostasis. Understanding these molecular mechanisms may provide new targets for the treatment of obesity. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Due to continuous changes in organizational environment, there is no warranty for long term survival in the market. Currently, those organizations can succeed that are agile and able to rapidly respond to environmental requirements. In this research a model has been proposed for applying proper strategies for achieving long term organizational success. The proposed model is an integration of Balanced Score Card (BSC approach, Fuzzy Quality Function Development (FQFD and Zero-One Goal Programming (ZOGP. In fact by BSC, appropriate strategic plans can be designed and prioritized by FQFD. Then, based on multiple objectives and existing problem constraints, feasible strategic plans are identified by ZOGP. Findings imply that decision making techniques can be well utilized in designing BSC through a structured methodology make improvement in all aspects and have a positive influence on organization's performance in long term .   Keywords : B alanced Score Card , Fuzzy Quality Function Development, Zero-One Goal Programming, Strategic plans

    Full Text Available The term “agility” - agile enterprise - was introduced by a group of American researchers led by R.Dove as a result of some studies in a program sponsored by the US government, a program that primarily aimed at exploring the possibilities of making up production systems which could compete with the efficient production system "lean", introduced in most Japanese companies. Researchers involved in this program have formed Agility Forum, which aims to develop the concepts introduced. In 2001 appears the first paper, by R. Dove, entitled “Response Ability - Understanding the Agile Enterprise”, John Wiley and Sons Editors, in which was synthesized the phase of research field. Agility can be defined as “the ability with which an organization manages to develop successfully in a business environment whose changes are unpredictable.” Being agile means to control change, to notice market opportunities and by being continuously innovating, to succed on the market. The purpose of this paper is to support the idea that agility is a feature derived from the design and also to show that by applying the principles of RRS, which characterize agile systems, it is confirmed the fact that any industrial production system which wishes to be agile it should be designed.

    Full Text Available Agile software development can be made successful, but there is no well-defined way how to achieve this. The problem is that the successful adoption of agile methods and practices is a complex process and this process should be customizable for a particular organization or a team. This research focuses on identification of agile methods and practices. Result of the research is the ranking of agile methods, practices and their usage trends. As some terms of agile software development are interpreted differently in different organizations and teams, terminology used is analyzed. Results of the research can be used as a reference material for those who are planning to adopt agile methods or are looking for the next agile practice to implement. Results will be used for the development of an expert system to support agile adoption.

    AGILE is an Italian Space Agency mission dedicated to the observation of the gamma-ray Universe. The AGILE very innovative instrumentation combines for the first time a gamma-ray imager (sensitive in the energy range 30 MeV - 50 GeV), a hard X-ray imager (sensitive in the range 18-60 keV) together with a Calorimeter (sensitive in the range 300 keV - 100 MeV) and an anticoincidence system. AGILE was successfully launched on April 23, 2007 from the Indian base of Sriharikota and was inserted in an equatorial orbit with a very low particle background. AGILE provides crucial data for the study of Active Galactic Nuclei, Gamma-Ray Bursts, pulsars, unidentified gamma-ray sources, Galactic compact objects, supernova remnants, TeV sources, and fundamental physics by microsecond timing. An optimal angular resolution (reaching 0.1-0.2 degrees in gamma-rays, 1-2 arcminutes in hard X-rays) and very large fields of view (2.5 sr and 1 sr, respectively) are obtained by the use of Silicon detectors integrated in a very compa...

    1993-01-01

    This report attempts to unify in a single document the results of a series of studies on fighter aircraft agility funded by the NASA Ames Research Center, Dryden Flight Research Facility and conducted at the University of Kansas Flight Research Laboratory during the period January 1989 through December 1993. New metrics proposed by pilots and the research community to assess fighter aircraft agility are collected and analyzed. The report develops a framework for understanding the context into which the various proposed fighter agility metrics fit in terms of application and testing. Since new metrics continue to be proposed, this report does not claim to contain every proposed fighter agility metric. Flight test procedures, test constraints, and related criteria are developed. Instrumentation required to quantify agility via flight test is considered, as is the sensitivity of the candidate metrics to deviations from nominal pilot command inputs, which is studied in detail. Instead of supplying specific, detailed conclusions about the relevance or utility of one candidate metric versus another, the authors have attempted to provide sufficient data and analyses for readers to formulate their own conclusions. Readers are therefore ultimately responsible for judging exactly which metrics are 'best' for their particular needs. Additionally, it is not the intent of the authors to suggest combat tactics or other actual operational uses of the results and data in this report. This has been left up to the user community. Twenty of the candidate agility metrics were selected for evaluation with high fidelity, nonlinear, non real-time flight simulation computer programs of the F-5A Freedom Fighter, F-16A Fighting Falcon, F-18A Hornet, and X-29A. The information and data presented on the 20 candidate metrics which were evaluated will assist interested readers in conducting their own extensive investigations.

  7. Balancing

    Science.gov (United States)

    Harteveld, Casper

    At many occasions we are asked to achieve a “balance” in our lives: when it comes, for example, to work and food. Balancing is crucial in game design as well as many have pointed out. In games with a meaningful purpose, however, balancing is remarkably different. It involves the balancing of three different worlds, the worlds of Reality, Meaning, and Play. From the experience of designing Levee Patroller, I observed that different types of tensions can come into existence that require balancing. It is possible to conceive of within-worlds dilemmas, between-worlds dilemmas, and trilemmas. The first, the within-world dilemmas, only take place within one of the worlds. We can think, for example, of a user interface problem which just relates to the world of Play. The second, the between-worlds dilemmas, have to do with a tension in which two worlds are predominantly involved. Choosing between a cartoon or a realistic style concerns, for instance, a tension between Reality and Play. Finally, the trilemmas are those in which all three worlds play an important role. For each of the types of tensions, I will give in this level a concrete example from the development of Levee Patroller. Although these examples come from just one game, I think the examples can be exemplary for other game development projects as they may represent stereotypical tensions. Therefore, to achieve harmony in any of these forthcoming games, it is worthwhile to study the struggles we had to deal with.

    The integration of balance and plyometric training has been shown to provide significant improvements in sprint, jump, agility, and other performance measures in young athletes. It is not known if a specific within session balance and plyometric exercise sequence provides more effective training adaptations. The objective of the present study was to investigate the effects of using a sequence of alternating pairs of exercises versus a block (series) of all balance exercises followed by a block of plyometric exercises on components of physical fitness such as muscle strength, power, speed, agility, and balance. Twenty-six male adolescent soccer players (13.9 ± 0.3 years) participated in an 8-week training program that either alternated individual balance (e.g., exercises on unstable surfaces) and plyometric (e.g., jumps, hops, rebounds) exercises or performed a block of balance exercises prior to a block of plyometric exercises within each training session. Pre- and post-training measures included proxies of strength, power, agility, sprint, and balance such as countermovement jumps, isometric back and knee extension strength, standing long jump, 10 and 30-m sprints, agility, standing stork, and Y-balance tests. Both groups exhibited significant, generally large magnitude (effect sizes) training improvements for all measures with mean performance increases of approximately >30%. There were no significant differences between the training groups over time. The results demonstrate the effectiveness of combining balance and plyometric exercises within a training session on components of physical fitness with young adolescents. The improved performance outcomes were not significantly influenced by the within session exercise sequence. Key points The combination of balance and plyometric exercises can induce significant and substantial training improvements in muscle strength, power, speed, agility, and balance with adolescent youth athletes The within training session

    To compare the impacts of Tai Chi, a standard balance exercise program, and a video game balance board program on postural control and perceived falls risk. Randomized controlled trial. Research laboratory. Independent seniors (N=40; 72.5±8.40) began the training, 27 completed. Tai Chi, a standard balance exercise program, and a video game balance board program. The following were used as measures: Timed Up & Go, One-Leg Stance, functional reach, Tinetti Performance Oriented Mobility Assessment, force plate center of pressure (COP) and time to boundary, dynamic posturography (DP), Falls Risk for Older People-Community Setting, and Falls Efficacy Scale. No significant differences were seen between groups for any outcome measures at baseline, nor were significant time or group × time differences for any field test or questionnaire. No group × time differences were seen for any COP measures; however, significant time differences were seen for total COP, 3 of 4 anterior/posterior displacement and both velocity, and 1 displacement and 1 velocity medial/lateral measure across time for the entire sample. For DP, significant improvements in the overall score (dynamic movement analysis score), and in 2 of the 3 linear and angular measures were seen for the sample. The video game balance board program, which can be performed at home, was as effective as Tai Chi and the standard balance exercise program in improving postural control and balance dictated by the force plate postural sway and DP measures. This finding may have implications for exercise adherence because the at-home nature of the intervention eliminates many obstacles to exercise training.

    2014-10-01

    Physical therapy intervention is the primary treatment for gait ataxia and imbalance in individuals with cerebellar damage. Our aim was to determine if a home balance exercise program is feasible for improving locomotor and balance abilities in these individuals. A total of 14 patients with cerebellar ataxia participated in a 6-week individualized home-based balance exercise program and attended 5 testing sessions (2 pretraining, 1 midtraining, 1 posttraining, and 1 one-month follow-up visit). Pretraining, posttraining, and follow-up testing included a neurological assessment, clinical gait and balance tests, and laboratory assessments of balance and walking. Participants kept logs of the frequency and level of balance challenge during their training. Walking speed improved across visits, as did stride length, percentage double-limb support time, Timed Up and Go (TUG), and Dynamic Gait Index. Post hoc comparisons in these measures revealed that significant rehabilitative improvements occurred over the 6-week training period, and all but TUG gains were retained 1 month later. There were no changes across the other measures for the group. Regression analysis indicated that improvements in walking speed were affected by the level of balance challenge but not by age, ataxia severity, proprioception, or duration of exercise. Improvement in locomotor performance in people with cerebellar ataxia was observable after a 6-week home balance exercise program. The exercise program must be designed to provide a significant challenge to the person's balance. © The Author(s) 2014.

    Bryant, P J

    2000-01-01

    AGILE is a program that works in the IBM-PC, MS-Windows environment and is dedicated to the interactive design of alternating-gradient lattices for synchrotrons and transfer lines. The program was originally intended as a teaching tool, but has been used mostly for professional design work and is subject to continuous development. It contains original algorithms for coupling, scattering and eddy currents, and some slightly unusual algorithms for off-axis orbits and space charge. There are also additional features such as engineering design aids, calculators for relativistic and synchrotron radiation parameters, expert routines for optimising slow extraction, fitting and matching, and the internal storage of constants for over 1000 stable and quasi-stable charged particles. The program is object-oriented and fully integrated into the Windows environment - it is not a shell. Apart from office work, AGILE is ideal for home use, design workshops and when travelling. It is particularly suited to practical problems...

  16. Perspectives on Agile Coaching

    Fraser, Steven; Lundh, Erik; Davies, Rachel; Eckstein, Jutta; Larsen, Diana; Vilkki, Kati

    There are many perspectives to agile coaching including: growing coaching expertise, selecting the appropriate coach for your context; and eva luating value. A coach is often an itinerant who may observe, mentor, negotiate, influence, lead, and/or architect everything from team organization to system architecture. With roots in diverse fields ranging from technology to sociology coaches have differing motivations and experience bases. This panel will bring together coaches to debate and discuss various perspectives on agile coaching. Some of the questions to be addressed will include: What are the skills required for effective coaching? What should be the expectations for teams or individu als being coached? Should coaches be: a corporate resource (internal team of consultants working with multiple internal teams); an integral part of a specific team; or external contractors? How should coaches exercise influence and au thority? How should management assess the value of a coaching engagement? Do you have what it takes to be a coach? - This panel will bring together sea soned agile coaches to offer their experience and advice on how to be the best you can be!

    Friedman, B.; Miller, M.

    2009-09-01

    In practice, it is difficult to determine the optimal amount to spend on marketing and administering a green pricing program. Budgets for marketing and administration of green pricing programs are a function of several factors: the region of the country; the size of the utility service area; the customer base and media markets encompassed within that service area; the point or stage in the lifespan of the program; and certainly, not least, the utility's commitment to and goals for the program. All of these factors vary significantly among programs. This report presents data on programs that have funded both marketing and program administration. The National Renewable Energy Laboratory (NREL) gathers the data annually from utility green pricing program managers. Programs reporting data to NREL spent a median of 18.8% of program revenues on marketing their programs in 2008 and 16.6% in 2007. The smallest utilities (those with less than 25,000 in their eligible customer base) spent 49% of revenues on marketing, significantly more than the overall median. This report addresses the role of renewable energy credit (REC) marketers and start-up costs--and the role of marketing, generally, in achieving program objectives, including expansion of renewable energy.

    2007-11-01

    Different coaching methods are often used to improve performance. This study compared the effectiveness of 2 methodologies for speed and agility conditioning for random, intermittent, and dynamic activity sports (e.g., soccer, tennis, hockey, basketball, rugby, and netball) and the necessity for specialized coaching equipment. Two groups were delivered either a programmed method (PC) or a random method (RC) of conditioning with a third group receiving no conditioning (NC). PC participants used the speed, agility, quickness (SAQ) conditioning method, and RC participants played supervised small-sided soccer games. PC was also subdivided into 2 groups where participants either used specialized SAQ equipment or no equipment. A total of 46 (25 males and 21 females) untrained participants received (mean +/- SD) 12.2 +/- 2.1 hours of physical conditioning over 6 weeks between a battery of speed and agility parameter field tests. Two-way analysis of variance results indicated that both conditioning groups showed a significant decrease in body mass and body mass index, although PC achieved significantly greater improvements on acceleration, deceleration, leg power, dynamic balance, and the overall summation of % increases when compared to RC and NC (p < 0.05). PC in the form of SAQ exercises appears to be a superior method for improving speed and agility parameters; however, this study found that specialized SAQ equipment was not a requirement to observe significant improvements. Further research is required to establish whether these benefits transfer to sport-specific tasks as well as to the underlying mechanisms resulting in improved performance.

  13. Decision Support for Iteration Scheduling in Agile Environments

    Science.gov (United States)

    Szőke, Ákos

    Today’s software business development projects often lay claim to low-risk value to the customers in order to be financed. Emerging agile processes offer shorter investment periods, faster time-to-market and better customer satisfaction. To date, however, in agile environments there is no sound methodological schedule support contrary to the traditional plan-based approaches. To address this situation, we present an agile iteration scheduling method whose usefulness is evaluated with post-mortem simulation. It demonstrates that the method can significantly improve load balancing of resources (cca. 5×), produce higher quality and lower-risk feasible schedule, and provide more informed and established decisions by optimized schedule production. Finally, the paper analyzes benefits and issues from the use of this method.

  14. Aircraft agility maneuvers

    Science.gov (United States)

    Cliff, Eugene M.; Thompson, Brian G.

    1992-01-01

    A new dynamic model for aircraft motions is presented. This model can be viewed as intermediate between a point-mass model, in which the body attitude angles are control-like, and a rigid-body model, in which the body-attitude angles evolve according to Newton's Laws. Specifically, consideration is given to the case of symmetric flight, and a model is constructed in which the body roll-rate and the body pitch-rate are the controls. In terms of this body-rate model a minimum-time heading change maneuver is formulated. When the bounds on the body-rates are large the results are similar to the point-mass model in that the model can very quickly change the applied forces and produce an acceleration to turn the vehicle. With finite bounds on these rates, the forces change in a smooth way. This leads to a measurable effect of agility.

    Considering the increasing expansion of economic and human activities on coastal zones, the concept of Integrated Coastal Zone Management (ICZM) emerges as a crutial need for the society. In order to implement such ICZM programs, the AGIL project is being developed through a Consortium, which integrates different skills: purely scientific ones, as well as products and trade services companies using Earth Observation (EO).Spatialized information resulting of EO processing is necessary to investigate and to update the knowledge on the littoral and his watershed. Two test sites (Réunion Island & Languedoc) have been selected for the ICZM approach in progress. The consortium AGIL attempts to gather its skills to propose expertise and a package of EO products, applied to ICZM.The AGIL "system" for representation and diffusion of a relevant information, comes up to three principal needs:-presentation of the scientific results, synthesized and validated by the users according to a specific investigation.-sharing information between members of the Consortium-exchange of information between the end-users.The adopted data-processing solution uses the concept of "distributed" system and respects the European directive for the spatialized data exchange.s

    The Telemetry Agile Manufacturing Effort (TAME) is an agile enterprising demonstration sponsored by the US Department of Energy (DOE). The project experimented with new approaches to product realization and assessed their impacts on performance, cost, flow time, and agility. The purpose of the project was to design the electrical and mechanical features of an integrated telemetry processor, establish the manufacturing processes, and produce an initial production lot of two to six units. This paper outlines the major methodologies utilized by the TAME, describes the accomplishments that can be attributed to each methodology, and finally, examines the lessons learned and explores the opportunities for improvement associated with the overall effort. The areas for improvement are discussed relative to an ideal vision of the future for agile enterprises. By the end of the experiment, the TAME reduced production flow time by approximately 50% and life cycle cost by more than 30%. Product performance was improved compared with conventional DOE production approaches.

    2017-09-14

    Falls incur significant health and economic costs, particularly among older adults. Physical activity has been found to be the single most important fall prevention behaviour an older adult can do. This manuscript describes Ottawa Public Health's (OPH) experience implementing the Better Strength, Better Balance! (BSBB) program, a fall prevention exercise program for older adults, through an innovative partnership with the local Recreation, Cultural & Facility Services (RCFS) Department. BSBB aims to reach 1300 community-dwelling adults (aged 65 years and older) per year through approximately 86-130 exercise programs. Designed as a universal program, BSBB addresses participation barriers such as transportation, cost and location. BSBB was enabled with funding from the Champlain Local Health Integration Network, and coincided with the implementation of an Older Adult Plan for the City of Ottawa. BSBB is a beginner-level, fall prevention exercise and education program that takes place twice a week, over 12 weeks. Certified RCFS instructors delivered the exercise components of the program and OPH staff incorporated fall prevention messaging and conducted the evaluation. The formative evaluation indicated that participants experienced improved strength and balance, decreased fear of falling and the intent to adopt new fall prevention behaviours following the program. The partnership between OPH and RCFS allowed both partners to leverage their unique and mutual strengths to continually improve the program. Improving access to strength and balance programming is an important public health strategy to reduce falls. The recreation sector is an ideal partner to help public health in this pursuit.

    Many jurisdictions in North America have implemented mandatory community service programs in high schools. However, little research exists examining the reasoning of youth themselves about such programs. This study examined how youth reason about community service programs, and how they balance the prosocial goals of these programs against their personal autonomy. Seventy-two participants between 10 and 18 years old evaluated voluntary community service along with 4 hypothetical mandatory programs that varied according to whether students or the government decided the areas in which students would serve, and whether a structured reflection component was included. The findings reveal that youth are not simply self-focused but rather balance and coordinate considerations of autonomy and community in their judgments and reasoning about community service.

J Strength Cond Res 30(9): 2514-2521, 2016-This study compared reactive agility movement time and unilateral (vertical, horizontal, and lateral) jump performance and kinetics between dominant and nondominant legs in Australian rules footballers (n = 31) to investigate the role of leg strength characteristics in reactive agility performance. Jumps involved jumping forward on 1 leg, then for maximum height or horizontal or lateral distance. Agility and movement time components of reactive agility were assessed using a video-based test. Correlations between each of the jumps were strong (r = -0.62 to -0.77), but between the jumps and agility movement time the relationships were weak (r = -0.25 to -0.33). Dominant leg performance was superior in reactive agility movement time (4.5%; p = 0.04), lateral jump distance (3%; p = 0.008), and lateral reactive strength index (4.4%; p = 0.03) compared with the nondominant leg. However, when the subjects were divided into faster and slower performers (based on their agility movement times) the movement time was significantly quicker in the faster group (n = 15; 12%; p agility performance seems limited, factors involved in producing superior lateral jump performance in the dominant leg may also be associated with advantages in agility performance in that leg. However, because reactive strength as measured by unilateral jumps seems to play a limited role in reactive agility performance and other factors such as skill, balance, and coordination, and also cognitive and decision-making factors, are likely to be more important.

  6. Developmental programming of energy balance regulation: is physical activity more 'programmable' than food intake?

    2016-02-01

    Extensive human and animal model data show that environmental influences during critical periods of prenatal and early postnatal development can cause persistent alterations in energy balance regulation. Although a potentially important factor in the worldwide obesity epidemic, the fundamental mechanisms underlying such developmental programming of energy balance are poorly understood, limiting our ability to intervene. Most studies of developmental programming of energy balance have focused on persistent alterations in the regulation of energy intake; energy expenditure has been relatively underemphasised. In particular, very few studies have evaluated developmental programming of physical activity. The aim of this review is to summarise recent evidence that early environment may have a profound impact on establishment of individual propensity for physical activity. Recently, we characterised two different mouse models of developmental programming of obesity; one models fetal growth restriction followed by catch-up growth, and the other models early postnatal overnutrition. In both studies, we observed alterations in body-weight regulation that persisted to adulthood, but no group differences in food intake. Rather, in both cases, programming of energy balance appeared to be due to persistent alterations in energy expenditure and spontaneous physical activity (SPA). These effects were stronger in female offspring. We are currently exploring the hypothesis that developmental programming of SPA occurs via induced sex-specific alterations in epigenetic regulation in the hypothalamus and other regions of the central nervous system. We will summarise the current progress towards testing this hypothesis. Early environmental influences on establishment of physical activity are likely an important factor in developmental programming of energy balance. Understanding the fundamental underlying mechanisms in appropriate animal models will help determine whether early life

    To evaluate the structure of the anatomy program in the first year medical curriculum of University of Split School of Medicine by comparing it with the recommendations by the Educational Affairs Committee of the American Association of Clinical Anatomists (AACA) and the Terminologia Anatomica (TA); we also quantitatively evaluated the organization of teaching material in contemporary topographical anatomy textbooks and matched them with the AACA recommendations, TA, and the curriculum of the anatomy course taught at Medical School in Split, Croatia. TA, official recommendations of the AACA, 6 contemporary anatomy textbooks, and the structure of the anatomy course were analyzed for the proportion of the terms or text devoted to standard topographical regions of the body. The findings were correlated using Spearman rho test. The curriculum outline correlated both with the AACA recommendations (Spearman rho=0.83, P=0.015) and TA (Spearman rho=0.73, P=0.046). Textbooks contained 8 distinct sections, 7 allocated to topographic anatomy regions and 1 to general anatomy concepts and principles. The structure of all textbooks correlated significantly with the course curriculum. However, 4 out of 6 textbooks did not correlate with TA and only a single textbook showed significant correlation with the AACA recommendations. Anatomy textbooks vary in the amount of text dedicated to different parts of topographical anatomy and are not quite concordant with curriculum recommendations and standard anatomical terminology. Planning the structure of an anatomy course should not be based on a single book or recommendation but on evidence.

    Each of the seven solar energy technologies that have been assessed in the study are treated: photovoltaic devices, solar thermal power systems, wind energy systems, solar heating and cooling systems, agricultural and industrial heat processes, biomass conversion technologies, and ocean thermal energy conversion systems. A brief technical overview of storage for solar electric technologies is presented and some principles concerning how different levels of success on electrical storage can affect the commercial viability of solar electric options are discussed. A description is given of the solar penetration model that was developed and applied as an analytical tool in the study. This computer model has served the primary purpose of evaluating the competiveness of the solar energy systems in the markets in which they are expected to compete relative to that of the alternative energy sources. This is done under a variety of energy supply, demand, and price conditions. The seven sections treating the solar energy technologies contain discussions on each of six subject areas: description of the technology; economic projections; the potential contribution of the technology in different marketplaces; environmental considerations; international potential; and the present and possible future emphases within the RD and D program. The priority item for each of the technology sections has been the documentation of the economic projections.

    Aim To evaluate the structure of the anatomy program in the first year medical curriculum of University of Split School of Medicine by comparing it with the recommendations by the Educational Affairs Committee of the American Association of Clinical Anatomists (AACA) and the Terminologia Anatomica (TA); we also quantitatively evaluated the organization of teaching material in contemporary topographical anatomy textbooks and matched them with the AACA recommendations, TA, and the curriculum of the anatomy course taught at Medical School in Split, Croatia. Methods TA, official recommendations of the AACA, 6 contemporary anatomy textbooks, and the structure of the anatomy course were analyzed for the proportion of the terms or text devoted to standard topographical regions of the body. The findings were correlated using Spearman ρ test. Results The curriculum outline correlated both with the AACA recommendations (Spearman ρ = 0.83, P = 0.015) and TA (Spearman ρ = 0.73, P = 0.046). Textbooks contained 8 distinct sections, 7 allocated to topographic anatomy regions and 1 to general anatomy concepts and principles. The structure of all textbooks correlated significantly with the course curriculum. However, 4 out of 6 textbooks did not correlate with TA and only a single textbook showed significant correlation with the AACA recommendations. Conclusion Anatomy textbooks vary in the amount of text dedicated to different parts of topographical anatomy and are not quite concordant with curriculum recommendations and standard anatomical terminology. Planning the structure of an anatomy course should not be based on a single book or recommendation but on evidence. PMID:19260144

    Davies, Rachel; Pullicino, James

    The surge in Agile adoption has created a demand for project managers rather than direct their teams. A sign of this trend is the ever-increasing number of people getting certified as scrum masters and agile leaders. Training courses that introduce agile practices are easy to find. But making the transition to coach is not as simple as understanding what agile practices are. Your challenge as an Agile Coach is to support your team in learning how to wield their new Agile tools in creating great software.

    2013-10-01

    This study explored balance performance and participant adherence to either the Wii Fit™ (Nintendo of America, Redmond, WA) or a proprioceptive BOSU(®) (Ashland, OH) ball balance program. Twenty university-aged participants were randomly allocated to either a Wii Fit or BOSU ball balance training program. Participants engaged in one of the two training regimens for 20 minutes, three times a week, for 4 weeks. Adherence was measured by recording attendance and time spent at each session. Motivational factors associated with adherence were assessed using the Physical Activity Enjoyment Scale. Balance was measured using a stabilometer. No significant difference in participant adherence was found between the groups. Significantly higher levels of activity enjoyment were reported from participants assigned to the Wii Fit intervention, and a positive correlation was found between physical activity enjoyment and adherence. A significant main effect for time demonstrating improved balance scores for both groups was found. No significant interaction between program type and time was found. Although both interventions led to balance improvements, Wii Fit participants reported significantly higher levels of activity enjoyment. Although these higher levels of enjoyment did not lead to a statistically significant difference between the groups with regard to the number of sessions attended, participants assigned to the Wii Fit group spent more time engaged in the balance training activities than those allocated to the BOSU group. Although this study is preliminary and has the limitations of being statistically underpowered and dissimilar from the unsupervised home-based programs often prescribed by health professionals, results suggest that exergaming-based balance training may be an important adjunct to traditional training programs.

    The aim of this study was to investigate the influence of a ballroom dancing program on the postural balance of institutionalized elderly residents. The sample consisted of 59 sedentary elderly residents of long-stay institutions who were randomly assigned to a ballroom dancing experimental group (EG, n=30) or a control group (CG, n=29). The ballroom dancing program consisted of three 50-min sessions each week on alternate days over a 12-week period. The dances included the foxtrot, waltz, rumba, swing, samba and bolero. The medical records of the subjects were reviewed to determine the number of falls they experienced in the three months prior to the intervention. Postural static balance was assessed using a Lizard (Med. EU., Italy, 2010) stabilometric and posturometric platform. Only patients in the EG lost a significant amount of weight (Δ=-2.85 kg) when comparing the pre- and post-test postural balance assessments. The intergroup comparison revealed a reduced lower limb weight distribution difference in the EG post-test compared to the CG post-test (p=0.012). In the intragroup comparison, the EG patients experienced significantly fewer falls post-test relative to pre-test (pdancing program. This activity improved balance and reduced the number of falls in this elderly population. Copyright © 2014. Published by Elsevier Ireland Ltd.

    Schneider, Edward T.

    1990-01-01

    NASA has utilized piloted simulators for nearly two decades to study high-angle-of-attack flying qualities, agility, and air-to-air combat. These studies have included assessments of an F-16XL aircraft equipped with thrust vectoring, an assessment of the F-18 HARV maneuvering requirements to assist in thrust vectoring control system design, and an agility assessment of the F-18. The F-18 agility assessment was compared with in-flight testing. Open-loop maneuvers such as 180-deg rolls to measure roll rate showed favorable simulator/in-flight comparison. Closed-loop maneuvers such as rolls to 90 deg with precision stops or certain maximum longitudinal pitching maneuvers showed poorer performance due to reduced aggressiveness of pilot inputs in flight to remain within flight envelope limits.

    2017-08-01

    We aimed to evaluate a strength and balance program delivered in the community. There is little evidence of implementation of evidence-based exercise in practice. The program was a step-down model, designed to encourage long-term exercise in community classes. The program consisted of a fully funded referral only evidence-based 12-week strength and balance (Community Otago) class, followed by an evidence-based continuous open-access community strength and balance class (Active Always). The program was offered to patients: 1) after formal falls rehabilitation (falls and fracture service); 2) after falls rehabilitation in intermediate care; and 3) referred by a GP who were not eligible for rehabilitation (preventative measure). Outcome evaluation used descriptive statistics to report changes in function, confidence in balance, hospital attendance/admission for falls/fractures and transition to community classes. Focus groups established participant experience/satisfaction. Seventy-nine participants were included, aged 56-96, and 53 (67%) were women. About 63.3% of patients transitioned to Active Always classes, demonstrating improvement in maintenance. Follow-up scores from baseline attendance at falls and fracture service to 12-weeks follow-up (24 weeks) in Community Otago showed the majority of patients improved their function (Timed up and Go), confidence (ConfBal) and lowered their falls risk (Tinetti). Follow-up of participants from Community Otago baseline to the end of 12-weeks showed improvement in function and confidence, but only a third of participants lowered their falls risk. Focus groups data suggest that continuity of delivery, the role of the instructor, health professional, and social and physical outcomes were essential for maintenance. A supportive environment can be created which encourages older adults' continued participation in group-based strength and balance, helping the delivery of evidence-based practice.

    2013-01-01

    Agile development methods began to emerge around 20 years ago. However, it was not until the early 2000s that they began to be widely used in industry. This growth was often due to the advent of Internet services requiring faster cycles of development in order to heighten the rate at which an ever-greater number of functionalities were made available. In parallel, user-centered design (UCD) methods were also becoming more and more widely used: hence, user-centered design and agile methods were bound to cross paths, at least in the telecoms industry!

    Full Text Available The integration of balance and plyometric training has been shown to provide significant improvements in sprint, jump, agility, and other performance measures in young athletes. It is not known if a specific within session balance and plyometric exercise sequence provides more effective training adaptations. The objective of the present study was to investigate the effects of using a sequence of alternating pairs of exercises versus a block (series of all balance exercises followed by a block of plyometric exercises on components of physical fitness such as muscle strength, power, speed, agility, and balance. Twenty-six male adolescent soccer players (13.9 ± 0.3 years participated in an 8-week training program that either alternated individual balance (e.g., exercises on unstable surfaces and plyometric (e.g., jumps, hops, rebounds exercises or performed a block of balance exercises prior to a block of plyometric exercises within each training session. Pre- and post-training measures included proxies of strength, power, agility, sprint, and balance such as countermovement jumps, isometric back and knee extension strength, standing long jump, 10 and 30-m sprints, agility, standing stork, and Y-balance tests. Both groups exhibited significant, generally large magnitude (effect sizes training improvements for all measures with mean performance increases of approximately >30%. There were no significant differences between the training groups over time. The results demonstrate the effectiveness of combining balance and plyometric exercises within a training session on components of physical fitness with young adolescents. The improved performance outcomes were not significantly influenced by the within session exercise sequence.

  5. Usability Evaluation Method for Agile Software Development

    Directory of Open Access Journals (Sweden)

    Saad Masood Butt

    2015-02-01

    Full Text Available Agile methods are the best fit for tremendously growing software industry due to its flexible and dynamic nature. But the software developed using agile methods do meet the usability standards? To answer this question we can see that majority of agile software development projects currently involve interactive user interface designs, which can only be possible by following User Centered Design (UCD in agile methods. The question here is, how to integrate UCD with agile models. Both Agile models and UCD are iterative in nature but agile models focus on coding and development of software; whereas, UCD focuses on user interface of the software. Similarly, both of them have testing features where the agile model involves automated tested code while UCD involves an expert or a user to test the user interface. In this paper, a new agile usability model is proposed and the evaluation is of the proposed model is presented by practically implementing it in three real life projects. . Key results from these projects clearly show: the proposed agile model incorporates usability evaluation methods, improves the relationship between usability experts to work with agile software experts; in addition, allows agile developers to incorporate the result from UCD into subsequent interactions.

    The Botswana water and surface energy balance research program was developed to study and evaluate the integrated use of multispectral satellite remote sensing for monitoring the hydrological status of the Earth's surface. The research program consisted of two major, mutually related components: a surface energy balance modeling component, built around an extensive field campaign; and a passive microwave research component which consisted of a retrospective study of large scale moisture conditions and Nimbus scanning multichannel microwave radiometer microwave signatures. The integrated approach of both components are explained in general and activities performed within the passive microwave research component are summarized. The microwave theory is discussed taking into account: soil dielectric constant, emissivity, soil roughness effects, vegetation effects, optical depth, single scattering albedo, and wavelength effects. The study site is described. The soil moisture data and its processing are considered. The relation between observed large scale soil moisture and normalized brightness temperatures is discussed. Vegetation characteristics and inverse modeling of soil emissivity is considered.

Fear of falling and quality of life scores were assessed at baseline and 12-month periods.Results: 146 subjects were recruited, 116 female (79.5% with a mean age of 67.1 years. At the end of the study, 49% of participants had not fallen. All of the balancing abilities were compared between frequent and infrequent fallers and were significantly improved (P < 0.001 except for functional reach in the frequent fall group. Most subjects (72%–79% complied well with the exercise program. However, compliance had no effect on balancing abilities. About 36.4% of participants had adverse events from exercise, of which knee pain was the top ranked. The quality of life and the fall efficacy scores increased significantly at the end of the study. Factors affecting falling were compliance with exercise (adjusted odds ratio [OR]: 2.55, 95% confidence intervals [CI]: 1.04, 6.30 and a history of falling ≥3 times in the previous year (adjusted OR: 3.76, 95% CI: 1.18, 11.98.Conclusion: Performing simply-designed balancing exercises, at least 3 days per week, can increase

Regarding Open-Eyes, Bonferroni post-hoc comparisons showed significant group-differences in TL for 1, 2, 5 & 6 sample conditions, and a slight trend toward significance in C90 1&5. TL also showed significant group-differences in Closed-Eyes 1, 5 & 6, while C90 only in 5 & 6 Closed-Eyes. Balance indicators TL and C90 show a different way regarding the training status. A 5-month MCTP reduces differences, but detraining quickly affects UNT. Although effective, short multicomponent interventions could lead to early worsening, so the ratio training-detraining might be considered in untrained elderly population.

    Fatigue and balance impairment leads to a loss of independence and are important to adequately manage. The objective of this study was to examine the effects of a resistance training program on dynamic balance and fatigue in patients with Parkinson's disease (PD). Randomized controlled trial. Forty-six patients with PD were randomly allocated to an intervention group receiving a 8-week resistance training program focused on lower limbs or to a control group. Balance was assessed using the Mini-BESTest and fatigue was assessed by the Piper Fatigue Scale. Patients in the intervention group improved significantly (p<0.05) on dynamic balance (reactive postural control and total values) and perceived fatigue. An 8-week resistance training program was found to be effective at improving dynamic balance and fatigue in patients with PD. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

  17. Effect of Hydrotherapy on Static and Dynamic Balance in Older Adults: Comparison of Perturbed and Non-Perturbed Programs

    Elham Azimzadeh

    2013-01-01

    Full Text Available Objectives: Falling is a main cause of mortality in elderly. Balance training exercises can help to prevent falls in older adults. According to the principle of specificity of training, the perturbation-based trainings are more similar to the real world. So these training programs can improve balance in elderly. Furthermore, exercising in an aquatic environment can reduce the limitations for balance training rather than a non-aquatic on. The aim of this study is comparing the effectiveness of perturbed and non-perturbed balance training programs in water on static and dynamic balance in aforementioned population group. Methods & Materials: 37 old women (age 80-65, were randomized to the following groups: perturbation-based training (n=12, non-perturbation-based training (n=12 and control (n=13 groups. Static and dynamic balance had been tested before and after the eight weeks of training by the postural stability test of the Biodex balance system using dynamic (level 4 and static platform. The data were analyzed by one sample paired t-test, Independent t-test and ANOVA. Results: There was a significant improvement for all indexes of static and dynamic balance in perturbation-based training (P<0.05. However, in non-perturbed group, all indexes were improved except ML (P<0.05. ANOVA showed that perturbed training was more effective than non-perturbed training on both static and dynamic balances. Conclusion: The findings confirmed the specificity principle of training. Although balance training can improve balance abilities, these kinds of trainings are not such specific for improving balance neuromuscular activities.The perturbation-based trainings can activate postural compensatory responses and reduce falling risk. According to results, we can conclude that hydrotherapy especially with perturbation-based programs will be useful for rehabilitation interventions in elderly .

    Full Text Available Objectives: Typical rehabilitation programs following total hip arthroplasty and total knee arthroplasty include joint range of motion and muscle-strengthening exercises. Balance and balance exercises following total hip arthroplasty and total knee arthroplasty have not received much attention. The purpose of this study was to determine whether an intervention of balance exercises added to a typical rehabilitation program positively affects patients’ balance. Methods: A total of 63 patients were provided with outpatient physical therapy at their home. Patients were randomly assigned to either typical (n = 33 or balance (n = 30 exercise group. The typical group completed seven typical surgery-specific joint range of motion and muscle-strengthening exercises, while the balance group completed the typical exercises plus three balance exercises. After 5 weeks of administering the rehabilitation program, patients’ balance was assessed on a force plate using 95% ellipse area of the center of pressure amplitude. Results: Patients in the balance group demonstrated significant reduction in the 95% ellipse area for the anterior and posterior lean standing conditions (p < 0.01. Conclusion: Balance exercises added to the typical outpatient physical therapy program resulted in significantly greater improvements in balance for participants with total hip arthroplasty or total knee arthroplasty, compared to the typical exercise program alone. Physical therapists might consider the use of balance exercises to improve balance in individuals in the acute post-operative phase following total hip arthroplasty or total knee arthroplasty.

  2. An Investigation of Agility Issues in Scrum Teams Using Agility Indicators

    Science.gov (United States)

    Pikkarainen, Minna; Wang, Xiaofeng

    Agile software development methods have emerged and become increasingly popular in recent years; yet the issues encountered by software development teams that strive to achieve agility using agile methods are yet to be explored systematically. Built upon a previous study that has established a set of indicators of agility, this study investigates what issues are manifested in software development teams using agile methods. It is focussed on Scrum teams particularly. In other words, the goal of the chapter is to evaluate Scrum teams using agility indicators and therefore to further validate previously presented agility indicators within the additional cases. A multiple case study research method is employed. The findings of the study reveal that the teams using Scrum do not necessarily achieve agility in terms of team autonomy, sharing, stability and embraced uncertainty. The possible reasons include previous organizational plan-driven culture, resistance towards the Scrum roles and changing resources.

    2014-04-01

    To measure pediatric program directors' (PDs') and trainees' perceptions of and expectations for the balance of service and education in their training programs. In fall 2011, an electronic survey was sent to PDs and trainees at Boston Children's Hospital. Respondents described perceptions and expectations for service and education and rated the education and service inherent to 12 vignettes. Wilcoxon rank sum tests measured the agreement between PD and trainee perceptions and ratings of service and education assigned to each vignette. Responses were received from 28/39 PDs (78%) and 223/430 trainees (52%). Seventy-five (34%) trainees responded that their education had been compromised by excessive service obligations; only 1 (4%) PD agreed (P education, only 3 (11%) PDs agreed (P education and clinical demands compared with 2 PDs (7%) (P educational. Trainees scored 6 vignettes as having greater educational value (P ≤ .01) and 10 as having lower service content (P ≤ .04) than PDs did. Trainees and medical educators hold mismatched impressions of their training programs' balance of service and education. Trainees are more likely to report an overabundance of service. These data may impact the interpretation of Accreditation Council for Graduate Medical Education survey results and should be incorporated into dialogue about future curricular design initiatives.

  5. Tailoring Agility: Promiscuous Pair Story Authoring and Value Calculation

    Science.gov (United States)

    Tendon, Steve

    This chapter describes how a multi-national software organization created a business plan involving business units from eight countries that followed an agile way, after two previously failed attempts with traditional approaches. The case is told by the consultant who initiated implementation of agility into requirements gathering, estimation and planning processes in an international setting. The agile approach was inspired by XP, but then tailored to meet the peculiar requirements. Two innovations were critical. The first innovation was promiscuous pair story authoring, where user stories were written by two people (similarly to pair programming), and the pairing changed very often (as frequently as every 15-20 minutes) to achieve promiscuity and cater for diverse point of views. The second innovation was an economic value evaluation (and not the cost) which was attributed to stories. Continuous recalculation of the financial value of the stories allowed to assess the projects financial return. In this case implementation of agility in the international context allowed the involved team members to reach consensus and unanimity of decisions, vision and purpose.

  6. Conceptualizing Interpersonal Relationships in Agile IS Development

    Madsen, Sabine; Matook, Sabine

    Agile information systems development (ISD) is a people-centered approach that emphasizes frequent interaction and genuine co-operation between customers and developers. While business relationships are the norm in the workplace, agile ISD leads to the creation of close interpersonal relationships....... Drawing on relationship theory and friendship literature we propose a theoretical framework of three types of workplace relationships. The framework is used for deriving theoretical preconceptions about agile relationships and their impact on the agile ISD team’s ability to deliver valuable, working...... software frequently. We also present the interpretive approach we will apply. An understanding of the relationship specific aspects of agile ISD as well as of the importance and impact of certain relationship characteristics can help explain why some agile projects succeed, while others fail...

    There is an evident lack of studies examining the factors associated with reactive agility performances. The aim of this study was to evaluate the association between anthropometrics, body composition, jumping capacity, reactive strength, and balance with a stop-and-go change of direction speed (CODS) and reactive agility. The total sample comprised 39 male (body height: 182.95 ± 5.19 cm; body mass: 80.66 ± 7.69 kg) and 34 female (body height: 171.45 ± 6.81 cm; body mass: 61.95 ± 6.70 kg) college-level athletes (21.9 ± 1.9 years of age). The variables included body height, body mass, the percentage of body fat (BF%), balance as measured by an overall-stability index, the countermovement jump (CMJ), a reactive-strength index (RSI), stop-and-go reactive agility, and stop-and-go CODS. To define the associations between motor and anthropometric variables with CODS and reactive agility, the participants were clustered into three achievement groups based on their CODS and reactive agility performances. The ANOVA showed a significant difference between the CODS-based achievement groups for the CMJ (F test = 3.45 and 3.60 for males and females, respectively; p agility achievement groups differed significantly in the RSI (F test = 6.46; p agility performance in sports.

    2014-04-01

    To investigate the effect of virtual reality (VR) and a tetra-ataxiometric posturography (Tetrax) program on stroke patients with impaired standing balance. Thirty acute stroke patients with impaired standing balance were recruited and randomly assigned to a VR, Tetrax, or control group. All patients received conventional balance training as a baseline; and VR and Tetrax patients received VR or Tetrax treatment, in addition. The primary outcome measures to evaluate the overall standing balance were the Berg Balance Scale (BBS) and the falling index (FI). The secondary outcome measures were the stability index (SI) and the weight distribution index (WDI), which were used to evaluate the balance status according to specific body positions. The FI, SI, and WDI were measured using the Tetrax instrument. The BBS and FI scores were improved in all groups, with no significant differences between groups. In open-eyed positions, the VR group showed significantly greater improvement in SI and WDI scores than the control group (pTetrax group showed significantly greater improvement in SI and WDI scores than the control group (pTetrax programs did not lead to an overall benefit in balance. VR and Tetrax did, however, demonstrate a benefit in specific positions. A Tetrax program may benefit patients with abnormal proprioceptive function, whereas a VR program may benefit patients with normal sensory function.

    2014-06-01

    Full Text Available Background: Stroke has been considered to be the most common cause of neurological disability with very high prevalence rate. The recovery of independence following stroke is a complex process requiring the reacquisition of many skills. Since controlling the body’s position in space is essential part of functional skills, restoration of balance is a critical part of the recovery of ability after stroke. Most of the work done regarding balance training in stroke subjects has focused on task-oriented activities and training under varied sensory input and found them to be effective. Studies have also compared the effect of stable and unstable surfaces on balance in stroke subjects and found that balance training on unstable surfaces is more effective in improving static and dynamic balance. There has not been any study till date investigating the effectiveness of balance training program on rocker board which is specific for stroke subjects who have difficulty in standing. Since balance training on rocker board in sitting has proved to be effective in improving balance in subjects with spinal cord injury who have difficulty in standing, there is a need to find out if similar balance training program on rocker board in sitting is also effective for improving balance of stroke subjects. Method: A Pilot study was performed on 10 stroke subjects selected through purposive sampling. Subjects were divided into two groups by randomization as control (CG and experimental group (EG. EG received balance training on a rocker board along with conventional physiotherapy program. The CG received only conventional physiotherapy program. Results: Post-intervention Berg balance scale score of EG and the CG was statistically significant (p < 0.05 in both the groups as compared to pre-treatment depicted through Wilcoxon signed rank analysis within the groups. Greater improvement was observed in the EG compared to the CG post-treatment, analysed through Mann

    2016-01-01

    Background and Purpose To determine if persons older than 65 years receiving a combination of physical therapy, occupational therapy, speech, or nursing interventions in their home demonstrated changes in gait/balance function after an episode of home care services. Methods Charts from 11 667 persons who were at risk for falling and who were participating in an exercise program in the home were included. Study design Data were retrieved from the Outcome and Assessment Information Set, Version B, and the computerized database of physical therapist–collected outcome data. Recorded physical therapist–data may have included a neuropathic pain rating, the Berg Balance Scale (BBS), the Performance Oriented Measurement Assessment (POMA), the Dynamic Gait Index (DGI), and the modified Clinical Test of Sensory Integration and Balance (mCTSIB). Data analysis Data were extracted by an honest broker and were analyzed. Mean (SD) change in each performance test and the percentage of participants in the total sample and in the 9 age/health condition strata that exceeded the minimum detectable change (MDC) for each gait/balance measure were described. The value of MDC95 describes the amount of true change in participant status beyond measurement error with 95% certainty. Results The gait/balance measures demonstrated MDCs ranging between 68% and 91% for the study sample. Mean (SD) of improvement on the BBS was 12 (8) points, with 88% of all participants exceeding the BBS MDC95 value of 5 points. Mean (SD) of improvement in gait/balance performance as measured by the POMA was 8 (4) points, with 91% of all participants exceeding the POMA MDC95 value of 3 points. Among all patients, mean (SD) of improvement on the DGI was 7 (4) points with 91% of all participants exceeding the DGI MDC95 value of 2 points by discharge. At admission, the median number of mCTSIB conditions that could be completed was 1 and the median number of completed conditions on the mCTSIB increased to 3 at

Prospective observational study with followup after 1, 3, 6, and 12 months with data from questionnaires and blood samples. Subjects. After 12 months, we had data from 524 subjects (= 60.6% of the initial samples. 84.1% of the subjects were women. The average BMI at baseline was 30.3 (SD = 5.7. Results. After 12 months, the average weight loss was 6.8 kg (SD = 7.1 kg. Program adherence declined over time but was still high after 12 months and showed a positive linear correlation with weight loss. Relevant blood parameters as well as HRQOL improved significantly. Conclusion. After 12 months, nearly two thirds of the samples had achieved >5% reduction of their initial weights. The high degree of program adherence is probably due to personal counseling and individually designed nutrition plans provided by the program.

    The Botswana water and surface energy balance research program was developed to study and evaluate the integrated use of multispectral satellite remote sensing for monitoring the hydrological status of the Earth's surface. Results of the first part of the program (Botswana 1) which ran from 1 Jan. 1988 - 31 Dec. 1990 are summarized. Botswana 1 consisted of two major, mutually related components: a surface energy balance modeling component, built around an extensive field campaign; and a passive microwave research component which consisted of a retrospective study of large scale moisture conditions and Nimbus scanning multichannel microwave radiometer microwave signatures. The integrated approach of both components in general are described and activities performed during the surface energy modeling component including the extensive field campaign are summarized. The results of the passive microwave component are summarized. The key of the field campaign was a multilevel approach, whereby measurements by various similar sensors were made at several altitudes and resolution. Data collection was performed at two adjacent sites of contrasting surface character. The following measurements were made: micrometeorological measurements, surface temperatures, soil temperatures, soil moisture, vegetation (leaf area index and biomass), satellite data, aircraft data, atmospheric soundings, stomatal resistance, and surface emissivity.

    2013-08-01

    The purpose of this study was to evaluate the effect of a 12-week-specific proprioceptive training program on postural stability, gait, balance, and fall prevention in adults older than 65 years. The present study was a controlled clinical trial. Forty-four community dwelling elderly subjects (61-90 years; mean age, 78.07 ± 5.7 years) divided into experimental (n = 20) and control (n = 24) groups. The participants performed the Berg balance test before and after the training program, and we assessed participants' gait, balance, and the risk of falling, using the Tinetti scale. Medial-lateral plane and anterior-posterior plane displacements of the center of pressure, Sway area, length and speed, and the Romberg quotient about surface, speed, and distance were calculated in static posturography analysis (EPS pressure platform) under 2 conditions: eyes open and eyes closed. After a first clinical evaluation, patients were submitted to 12 weeks proprioception training program, 2 sessions of 50 minutes every week. This program includes 6 exercises with the BOSU and Swiss ball as unstable training tools that were designed to program proprioceptive training. The training program improved postural balance of older adults in mediolateral plane with eyes open (p 0.05). After proprioception training, gait (Tinetti), and balance (Berg) test scores improved 14.66% and 11.47% respectively. These results show that 12 weeks proprioception training program in older adults is effective in postural stability, static, and dynamic balance and could lead to an improvement in gait and balance capacity, and to a decrease in the risk of falling in adults aged 65 years and older.

    The purposes of this study was to develop a comprehensive community-based fall prevention program and to test the effects of the program on the muscle strength, postural balance and fall efficacy for elderly people. The design of this study was a nonequivalent control group pretest-posttest design. There were 28 participants in the experimental group and 29 in the control group. The program consisted of balance exercises, elastic resistance exercises and prevention education. The program was provided five times a week for 8 weeks and each session lasted 90 minutes. Data were analyzed using χ²-test, independent t-test and paired t-test using the SPSS program. Muscle strength of the lower extremities, postural balance and fall efficacy scores significantly improved in the experimental group compared to the control group. These results suggest that this program can improve lower extremity muscle strength, postural balance and fall efficacy in elders. Therefore, this program is recommended for use in fall prevention programs for elders living in the community.

  13. Some Findings Concerning Requirements in Agile Methodologies

    Science.gov (United States)

    Rodríguez, Pilar; Yagüe, Agustín; Alarcón, Pedro P.; Garbajosa, Juan

    Agile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies.

    2014-12-01

    To evaluate the effects of a balance exercise program on falls in people with mild to moderate multiple sclerosis (MS). Multicenter, single-blinded, single-group, pretest-posttest trial. Seven rehabilitation units within 5 county councils. Community-dwelling adults with MS (N=32) able to walk 100m but unable to maintain 30-second tandem stance with arms alongside the body. Seven weeks of twice-weekly, physiotherapist-led 60-minute sessions of group-based balance exercise targeting core stability, dual tasking, and sensory strategies (CoDuSe). Primary outcomes: number of prospectively reported falls and proportion of participants classified as fallers during 7 preintervention weeks, intervention period, and 7 postintervention weeks. Secondary outcomes: balance performance on the Berg Balance Scale, Four Square Step Test, sit-to-stand test, timed Up and Go test (alone and with cognitive component), and Functional Gait Assessment Scale; perceived limitations in walking on the 12-item MS Walking Scale; and balance confidence on the Activities-specific Balance Confidence Scale rated 7 weeks before intervention, directly after intervention, and 7 weeks later. Number of falls (166 to 43; P≤.001) and proportion of fallers (17/32 to 10/32; P≤.039) decreased significantly between the preintervention and postintervention periods. Balance performance improved significantly. No significant differences were detected for perceived limitations in walking, balance confidence, the timed Up and Go test, or sit-to-stand test. The CoDuSe program reduced falls and proportion of fallers and improved balance performance in people with mild to moderate MS but did not significantly alter perceived limitations in walking and balance confidence.

    The objective of this study was to assess the effect of comprehensive exercise program widely accepted as a community-based physical intervention for the prevention of falling in the elderly persons on their controlling standing balance. Twenty-six community-dwelling elderly persons (13 males and females; 69.8 ± 2.8 years old) participated in this study. Daily exercise was comprised of walking for more than 30 min, stretching, muscle strengthening and balance exercise without exercise equipments. The intervention was continued for three months. Indicators of standing balance related to static balance, dynamic balance and postural response were measured before and after the intervention. As an effect of the intervention on static balance, the sway of center of pressure (COP) in the static stance significantly increased. In the dynamic balance, significant improvements were observed in one leg standing time, the 10-m gait time, functional reach. Additionally, the maximal movable length of COP which subjects can move voluntarily to right and left significantly increased. In the postural response, the integrated electromyography (IEMG) induced by postural response for sudden postural perturbation significantly decreased in the lower leg muscles. Since less muscular activities were sufficient to maintain posture, it was suggested that postural response was elicited more efficiently following the intervention. This study suggested that the comprehensive exercise program, which has been widely introduced as community-based interventions for the prevention of falling, have extensive effects on the control of standing balance covering static balance, dynamic balance and postural response in the elderly persons.

    The purpose of this study was to examine the effect of a rhythmic gymnastics program on the dynamic balance ability of a group of adults with intellectual disability (ID). The sample consisted of 18 adults with ID. The control group consisted of 8 adults and an intervention group of 10. The subjects were assigned to each group according to their desire to participate or not in the intervention program. Both groups were comparable in terms of age, weight, height, IQ, and socioeconomic background. The intervention group received a 12-week rhythmic gymnastics program at a frequency of 3 lessons per week, of 45 minutes. The methods of data collection included pre/post-test measurements of the dynamic balance for all subjects of both groups. The dynamic balance ability was measured by means of a balance deck (Lafayette) and was determined by the number of seconds the subject could remain standing on the platform of the stabilometer in durations of 30-, 45-, and 60-second intervals. As the results indicated, the intervention group showed a statistically significant improvement (p rhythmic gymnastics program when compared with the control group. It is concluded that adults with ID can improve their balance ability with the application of a well-designed rhythmic gymnastics program.

    The next century will witness at least two great revolutions in the way goods are produced. First, workers will use the medium of virtual reality in all aspects of marketing, research, development, prototyping, manufacturing, sales and service. Second, market forces will drive manufacturing towards small-lot production and just-in-time delivery. Already, we can discern the merging of these megatrends into what some are calling agile manufacturing. Under this new paradigm, parts and processes will be designed and engineered within the mind of a computer, tooled and manufactured by the offspring of today's rapid prototyping equipment, and evaluated for performance and reliability by advanced nondestructive evaluation (NDE) techniques and sophisticated computational models. Computed tomography (CT) is the premier example of an NDE method suitable for future agile manufacturing activities. It is the only modality that provides convenient access to the full suite of engineering data that users will need to avail themselves of computer- aided design, computer-aided manufacturing, and computer- aided engineering capabilities, as well as newly emerging reverse engineering, rapid prototyping and solid freeform fabrication technologies. As such, CT is assured a central, utilitarian role in future industrial operations. An overview of this exciting future for industrial CT is presented.

    In 2004, Ethiopia introduced a community-based Health Extension Program to deliver basic and essential health services. We developed a comprehensive performance scoring methodology to assess the performance of the program. A balanced scorecard with six domains and 32 indicators was developed. Data collected from 1,014 service providers, 433 health facilities, and 10,068 community members sampled from 298 villages were used to generate weighted national, regional, and agroecological zone scores for each indicator. The national median indicator scores ranged from 37% to 98% with poor performance in commodity availability, workforce motivation, referral linkage, infection prevention, and quality of care. Indicator scores showed significant difference by region (P < 0.001). Regional performance varied across indicators suggesting that each region had specific areas of strength and deficiency, with Tigray and the Southern Nations, Nationalities and Peoples Region being the best performers while the mainly pastoral regions of Gambela, Afar, and Benishangul-Gumuz were the worst. The findings of this study suggest the need for strategies aimed at improving specific elements of the program and its performance in specific regions to achieve quality and equitable health services. © The American Society of Tropical Medicine and Hygiene.

    Few studies have reported energy balance-related behavior (EBRB) change for peer leaders delivering health promotion programs to younger students in secondary schools. Our study assessed the impact of the Students As LifeStyle Activists (SALSA) program on SALSA peer leaders' EBRBs, and their intentions regarding these behaviors. We used a pre-post study design to assess changes in EBRBs and intentions of Year 10 secondary school students (15-16 year olds) who volunteered to be peer leaders to deliver the SALSA program to Year 8 students (13-14 year olds). This research is part of a larger study conducted during 2014 and 2015 in 23 secondary schools in Sydney, Australia. We used an online questionnaire before and after program participation to assess Year 10 peer leaders' fruit and vegetable intake, daily breakfast eating, sugar sweetened beverage (SSB) intake, moderate-to-vigorous physical activity (MVPA) participation and school-day recreational screen time behaviors and intentions regarding these EBRBs. Generalized estimating equations with a robust variance structure and exchangeable correlation structure were used to estimate the individual-level summary statistics and their 95% CIs, adjusted for clustering. We further assessed the effect of covariates on EBRB changes. There were significant increases in the proportion of Year 10 peer leaders (n = 415) who reported eating ≥2 serves fruit/day fruit from 54 to 63% (P leaders recreational screen time differed by socio-economic status (P leaders' intentions, except MVPA which remained stable.

    This study aimed to examine the validity, reliability, and sensitivity of a new test of planned agility in elite taekwondo athletes and to establish its relationship with sprint-time, jumping ability, and dynamic balance. Twenty-seven (20 males and 7 females) taekwondo athletes participated to this study. They performed taekwondo-specific agility test (TSAT) in two occasions (i.e., test-retest). Additionally, they performed jumping ability (i.e., squat jump, countermovement jump, standing long jump, and three-hop jump), sprint-time (5-m and 20-m dash), and dynamic balance (i.e., Y-test) tests along with a planned agility test (i.e., T-test). To establish TSAT's construct validity, two subgroups were identified based on their international and national taekwondo results: top-elite (9 males and 2 females) and elite (11 males and 2 females). TSAT showed high relative and absolute reliability as well as a good ability to detect small and meaningful performance change. Top-elite athletes showed greater (pagility test. Additionally, results showed moderate to large associations between TSAT and jumping ability, sprint-time, and dynamic balance tests. The TSAT might be considered as a valid and reliable test to evaluate specific agility of taekwondo athletes.

    Losses in lower extremity muscle strength/power, muscle mass and deficits in static and particularly dynamic balance due to aging are associated with impaired functional performance and an increased fall risk. It has been shown that the combination of balance and strength training (BST) mitigates these age-related deficits. However, it is unresolved whether supervised versus unsupervised BST is equally effective in improving muscle power and balance in older adults. This study examined the impact of a 12-week BST program followed by 12 weeks of detraining on measures of balance and muscle power in healthy older adults enrolled in supervised (SUP) or unsupervised (UNSUP) training. Sixty-six older adults (men: 25, women: 41; age 73 ± 4 years) were randomly assigned to a SUP group (2/week supervised training, 1/week unsupervised training; n = 22), an UNSUP group (3/week unsupervised training; n = 22) or a passive control group (CON; n = 22). Static (i.e., Romberg Test) and dynamic (i.e., 10-meter walk test) steady-state, proactive (i.e., Timed Up and Go Test, Functional Reach Test), and reactive balance (e.g., Push and Release Test), as well as lower extremity muscle power (i.e., Chair Stand Test; Stair Ascent and Descent Test) were tested before and after the active training phase as well as after detraining. Adherence rates to training were 92% for SUP and 97% for UNSUP. BST resulted in significant group × time interactions. Post hoc analyses showed, among others, significant training-related improvements for the Romberg Test, stride velocity, Timed Up and Go Test, and Chair Stand Test in favor of the SUP group. Following detraining, significantly enhanced performances (compared to baseline) were still present in 13 variables for the SUP group and in 10 variables for the UNSUP group. Twelve weeks of BST proved to be safe (no training-related injuries) and feasible (high attendance rates of >90%). Deficits of balance and lower extremity muscle power can be

    A group of 16 healthy older adults participated in a movement with music program to enhance physical flexibility, balance, and gait speed. The program, designed by a Laban Movement Analyst, consisted of 14 movement sequences set to music composed to reflect the dynamics, rhythm, timing, and phrasing of the movements. After 5 weeks, individuals showed statistically significant increases in measures of one-foot stance balance, gait speed, and functional reach. From the 5th to the 14th week, improvements continued in all measures but were not statistically significant.

    Global health practitioners may feel frustration that current models of global health research, delivery, and implementation are overly focused on specific interventions, slow to provide health services in the field, and relatively ill-equipped to adapt to local contexts. Adapting design principles from the agile software development movement, we propose an analogous approach to designing global health programs that emphasizes tight integration between research and implementation, early involvement of ground-level health workers and program beneficiaries, and rapid cycles of iterative program improvement. Using examples from our own fieldwork, we illustrate the potential of 'agile global health' and reflect on the limitations, trade-offs, and implications of this approach.

    Pikkarainen, Minna

    The amount of software is increasing in the different domains in Europe. This provides the industries in smaller countries good opportunities to work in the international markets. Success in the global markets however demands the rapid production of high quality, error free software. Both CMMI and agile methods seem to provide a ready solution for quality and lead time improvements. There is not, however, much empirical evidence available either about 1) how the integration of these two aspects can be done in practice or 2) what it actually demands from assessors and software process improvement groups. The goal of this paper is to increase the understanding of CMMI and agile integration, in particular, focusing on the research question: how to use ‘lightweight’ style of CMMI assessments in agile contexts. This is done via four case studies in which assessments were conducted using the goals of CMMI integrated project management and collaboration and coordination with relevant stakeholder process areas and practices from XP and Scrum. The study shows that the use of agile practices may support the fulfilment of the goals of CMMI process areas but there are still many challenges for the agile teams to be solved within the continuous improvement programs. It also identifies practical advices to the assessors and improvement groups to take into consideration when conducting assessment in the context of agile software development.

    Full Text Available The aim of this paper is to present the quantitative perspective of the agile transformation processes in IT organisations. The phenomenon of agile transformation becomes a complex challenge for an IT organisation since it has not been analysed in detail so far. There is no research on the readiness of IT organisations to realise agile transformation processes. Such processes also prove to have uncontrolled character. Therefore, to minimise the risk of failure referring to the realisation of transformation processes, it is necessary to monitor them. It is also necessary to identify and analyse such processes to ensure their continuous character.

    Picard, Willy

    Despite many works on collaborative networked organizations (CNOs), CSCW, groupware, workflow systems and social networks, computer support for virtual teams is still insufficient, especially support for agility, i.e. the capability of virtual team members to rapidly and cost efficiently adapt the way they interact to changes. In this paper, requirements for computer support for agile virtual teams are presented. Next, an extension of the concept of social protocol is proposed as a novel model supporting agile interactions within virtual teams. The extended concept of social protocol consists of an extended social network and a workflow model.

    The purposes of this study were to compare postural stability between obese and lean subjects and to investigate the effect of a 3-week body weight reduction (BWR) program entailing specific balance training on postural stability of extremely obese patients. Time of balance maintenance and mean error on the medial-lateral direction at the trunk and lower limb level were assessed during a single limb stance on a movable platform in 19 non-obese and in 20 extremely obese individuals (age range: 20-40 yr). Time of balance maintenance was shorter (obese: 21.1+/-7.7 vs lean: 27.3+/-3.1 sec) and medial-lateral sway of the trunk was larger in obese (5.4+/-3.2 degrees) than in lean (3.2+/-1.1 degrees) subjects (pprogram (energy-restricted diet, moderate physical exercise, nutritional education and psychological counselling) combined with or without 6 sessions of specific balance training on a movable platform. BWR plus specific balance training enhanced time of balance maintenance (pre: 23.8+/-7.2 vs post: 30.0+/-0.0 sec) and reduced the trunk sway (5.2+/-2.8 degrees vs 2.6+/-0.9 degrees ) more than BWR alone (pprogram. It was concluded that balance improvement is an important goal of rehabilitation, that would probably reduce the propensity of overweight individuals to fall while performing everyday activities.

    [Purpose] The purpose of this study was to investigate the effects of an 8-week balance exercise and elastic-resistance exercise program on muscle strength and balance of the old-old elderly (over the age of 75). [Subjects and Methods] Fifty-five elderly persons were recruited from the community and assigned to three groups for convenience: balance exercise (intervention group 1; INT 1), resistance exercise (intervention group 2; INT 2), and control (CON) groups. The intervention was performed twice a week at a senior center and three times a week at home for 8 weeks. Muscle strength and balance were evaluated before and at the end of the trial, using a PowertrackIIand Tetrax. [Results] There were significant improvements in the strength of all seven muscle groups and balance in the INT 2 group. In the INT 1 group, there were significant improvements in the strength of all muscle groups except for the knee flexor and ankle plantar flexor muscle groups. [Conclusion] This study demonstrated that an intervention using balance exercises or elastic-resistance exercises is effective at improving the muscle strength and balance of the old-old elderly. These type of exercises should be appropriate for the physical characteristics of the subjects.

    Physical activity training programs in older adults have recognized health benefits. Evidence suggests that training should include a combination of progressive resistance, balance, and functional training. Our aim was to assess the effects of a simple physical activity program working on strength, flexibility, cardiovascular fitness, and balance in older adults, as well as the effects of a detraining period, at various different ages. This was longitudinal prospective study, including a convenience sample of 227 independent older adults (54 men, 173 women) who completed a simple 9-month training program and 3-month detraining follow-up. The subjects were categorized into two age groups (65-74 [n = 180], and >74 years [n = 47]). At the beginning of the study (baseline), the end of the training period, and 3 months later (postdetraining), body mass index, body fat percentage, triceps skinfold thickness, hand grip strength, lower limb and trunk flexibility, resting heart rate, heart rate after exercise, and balance were measured, while VO(2 max) was estimated using the Rockport fitness test and/or measured directly. Significant improvements in strength (p < .0001), flexibility (p < .0001), heart rate after exercise (p < .0001), and balance (p < .0001) were observed at the end of the training program. Flexibility and balance (p < .0001) improvements were maintained at the end of the detraining. A simple long-term physical activity training program increases strength in both sexes, improves flexibility in women, and improves balance in older adults. The results also indicate the importance of beginning early in old age and maintaining long-term training. © 2013 Association of Rehabilitation Nurses.

    There is growing evidence for the positive effects of exercise training programs on balance control in Parkinson disease (PD). To be effective, balance training needs to be specific, progressive, and highly challenging. Little evidence exists, however, for how people with PD-related balance impairments perceive highly challenging and progressive balance training programs with dual-task components. The purpose of this study was to explore and describe perceptions of a highly challenging balance training program among people with mild to moderate PD. This study was qualitative in nature. In-depth interviews were conducted with 13 individuals with mild to moderate PD who had participated in a highly challenging balance training program. Interview transcripts were analyzed using qualitative content analysis, with an inductive approach. The analysis revealed 3 subthemes concerning participants' perceptions of highly challenging and progressive balance training: (1) movement to counter the disease, (2) dual-task training in contrast to everyday strategies, and (3) the struggle to maintain positive effects. The first subtheme reflects how physical activity was used as a short-term and long-term strategy for counteracting PD symptoms and their progression. The second subtheme incorporates the described experiences of being maximally challenged in a secure and supportive group environment, circumstances that stood in contrast to participants' everyday lives. The third subtheme describes participants' long-term struggle to maintain program effects on cognitive and physical function in the face of disease progression. Interpretation of the underlying patterns of these subthemes resulted in one overarching theme: training at the limits of balance capacity causes a rethinking motor and cognitive resources. The findings of this study cannot be considered to reflect the beliefs of those with weaker or negative beliefs concerning physical activity or be transferred to those at

    The paper aims to define and describe test methods and metrics to assess industrial robot system agility in both simulation and in reality. The paper describes test methods and associated quantitative and qualitative metrics for assessing robot system efficiency and effectiveness which can then be used for the assessment of system agility. The paper describes how the test methods were implemented in a simulation environment and real world environment. It also shows how the metrics are measured and assessed as they would be in a future competition. The test methods described in this paper will push forward the state of the art in software agility for manufacturing robots, allowing small and medium manufacturers to better utilize robotic systems. The paper fulfills the identified need for standard test methods to measure and allow for improvement in software agility for manufacturing robots.

    Full Text Available The 21st century started as the era of agile methods and technologies which combine adaptable and highly flexible methods designed to help teams to develop applications faster and safer. The challenge is to adapt just enough technology to enhance the performance of teams which are using agile methods and to avoid going back to weak workflow ideas of the industrial era. In this paper, I will present some relevant agile tools that could improve every software development project and I will also mention the features and criteria used for evaluating currently existing tools. Finally, I will propose a classification model to the appropriate agile tool selection, but keep in mind that in order to be successful, organizations and teams do need to deal first with the issues that accompany product complexity and growing teams.

    Full Text Available Yocheved Laufer, Gali Dar, Einat Kodesh Physical Therapy Department, Faculty of Social Welfare and Health Sciences, University of Haifa, Haifa, Israel Background: Exercise programs that challenge an individual’s balance have been shown to reduce the risk of falls among older adults. Virtual reality computer-based technology that provides the user with opportunities to interact with virtual objects is used extensively for entertainment. There is a growing interest in the potential of virtual reality-based interventions for balance training in older adults. This work comprises a systematic review of the literature to determine the effects of intervention programs utilizing the Nintendo Wii console on balance control and functional performance in independently functioning older adults.Methods: Studies were obtained by searching the following databases: PubMed, CINAHL, PEDro, EMBASE, SPORTdiscus, and Google Scholar, followed by a hand search of bibliographic references of the included studies. Included were randomized controlled trials written in English in which Nintendo Wii Fit was used to enhance standing balance performance in older adults and compared with an alternative exercise treatment, placebo, or no treatment.Results: Seven relevant studies were retrieved. The four studies examining the effect of Wii-based exercise compared with no exercise reported positive effects on at least one outcome measure related to balance performance in older adults. Studies comparing Wii-based training with alternative exercise programs generally indicated that the balance improvements achieved by Wii-based training are comparable with those achieved by other exercise programs.Conclusion: The review indicates that Wii-based exercise programs may serve as an alternative to more conventional forms of exercise aimed at improving balance control. However, due to the great variability between studies in terms of the intervention protocols and outcome measures, as

    The rapid and optimal design of new goods is essential for meeting national objectives in advanced manufacturing. Currently almost all manufacturing procedures involve the determination of some optimal design parameters. This process is iterative in nature and because it is usually done manually it can be expensive and time consuming. This report describes the results of an LDRD, the goal of which was to develop optimization algorithms and software tools that will enable automated design thereby allowing for agile manufacturing. Although the design processes vary across industries, many of the mathematical characteristics of the problems are the same, including large-scale, noisy, and non-differentiable functions with nonlinear constraints. This report describes the development of a common set of optimization tools using object-oriented programming techniques that can be applied to these types of problems. The authors give examples of several applications that are representative of design problems including an inverse scattering problem, a vibration isolation problem, a system identification problem for the correlation of finite element models with test data and the control of a chemical vapor deposition reactor furnace. Because the function evaluations are computationally expensive, they emphasize algorithms that can be adapted to parallel computers.

  13. The National Energy Strategy: A balanced program?. Proceedings of the nineteenth annual Illinois energy conference

    Energy Technology Data Exchange (ETDEWEB)

    1991-12-31

    The Nineteenth Annual Illinois Energy Conference was held in Chicago, Illinois November 1991. It was organized by the Energy Resources Center, University of Illinois at Chicago with major support provided by the US Environmental Protection Agency, the US Department of Energy, the Illinois Commerce Commission, the Illinois Department of Energy and Natural Resources, and the Citizens Council on Energy Resources. The conference program was developed by a planning committee who drew upon Illinois energy and environmental specialists from the major sectors including energy industries, environmental organizations, research universities, utility companies, federal, state and local government agencies, and public interest groups. The members of the planning committee were brought together for a full-day session where they were asked to assess the political, economic, and social impacts of the proposed National Energy Strategy as it relates to Illinois and the Midwest region. Within this context, the planning committee identified several major issues including: (1) Is the proposed plan a balanced strategy; (2) What are the NES impacts on the transportation sector; (3) What are the opportunities for improved efficiency in the Electric Utility Sector; and (4) What is the role of advanced research and development.

    Athletes incorporate afferent signals from the mechanoreceptors of their plantar feet to provide information about posture, stability, and joint position. Sub-threshold stochastic resonance (SR) sensory enhancing insoles have been shown to improve balance and proprioception in young and elderly participant populations. Balance and proprioception are correlated with improved athletic performance, such as agility. Agility is defined as the ability to quickly change direction. An athlete's agility is commonly evaluated during athletic performance testing to assess their ability to participate in a competitive sporting event. Therefore, the purpose of this study was to examine the effects of SR insoles during a hexagonal agility task routinely used by coaches and sports scientists. Twenty recreational athletes were recruited to participate in this study. Each athlete was asked to perform a set of hexagonal agility trials while SR stimulation was either on or off. Vicon motion capture was used to measure feet position during six successful trials for each stimulation condition. Stimulation condition was randomized in a pairwise fashion. The study outcome measures were the task completion time and the positional accuracy of footfalls. Pairwise comparisons revealed a 0.12s decrease in task completion time (p=0.02) with no change in hopping accuracy (p=0.99) when SR stimulation was on. This is the first study to show athletic performance benefits while wearing proprioception and balance improving equipment on healthy participants. With further development, a self-contained sensory enhancing insole device could be used by recreational and professional athletes to improve movements that require rapid changes in direction.

    The objective of the study was to examine the effects of a 16-week walking program on food group preferences and energy balance of sedentary, moderately obese (body mass index, 29-35 kg/m(2)), postmenopausal Caucasian women, aged 60 ± 5 years old. One hundred and fifty-six volunteers were subjected to 3 sessions/week of 45 min of walking at 60% of heart rate reserve. Total energy intake (TEI) and food group preferences (3-day dietary record), total energy expenditure (TEE, 3-day physical activity diary), cardiorespiratory fitness (2-km walking test), anthropometry, and body composition (bioelectrical impedance) were measured before and after walking. Data were statistically analyzed using an ANOVA with repeated measures on 1 factor (time). The modest increase in TEE of 151 ± 24 kcal/day (p < 0.0001) leads to body weight, fat mass losses, and waist girth reduction (p < 0.0001). TEI remained unchanged despite a slight decrease in carbohydrate intake and a minor increase in protein intake (p < 0.05). Analysis of food records revealed a decreased consumption of fruits (p < 0.05) and sweet and fatty foods (p < 0.01), but an increase in oil consumption (p < 0.0001) after walking. Women with the highest body weight loss showed the greatest reduction in the consumption of fruits, sugar, sweet foods, and fatty foods (p < 0.05). Women with the greatest fat mass loss showed the highest decrease in fatty food intake (p < 0.05). In conclusion, although our walking program changed some food group consumption patterns, body weight loss was primarily because of the increased TEE.

    The MATBAL computer program was designed and used by Ashland Synthetic Fuels, Inc., to perform material balance calculations for the H-Coal Pilot Plant at Catlettsburg, Kentucky. All of the material balance information generated at the Pilot Plant and the MATBAL code are stored on an IBM 3033 computer at the Oak Ridge National Laboratory. The MATBAL source code from ASFI was supplemented by McAuto (a McDonald-Douglas Corp. subsidiary), while the Pilot Plant data were obtained directly from McAuto. All of the material balance examples and results shown in this report were performed for Pilot Plant Section 200, the liquefaction section. The MATBAL program allows the user to retrieve, screen, and correct process variables (temperatures, pressures, tank levels, flow rates, etc.) and analytical data before performing the material balance calculations. A matrix format facilitates changes to the input data, elemental point numbers (EPNs), and sample point numbers (SPNs), allowing a large degree of flexibility in defining the material balance envelope. The use of intermediate data storage files saves time and computer costs in the data reduction and material balance calculations. The data on flow rates, elemental analyses, and compositional analyses for each stream are stored along with the data on accumulation, elemental analyses, and compositional analyses for each vessel. The headings, EPNs and SPNs, for both streams and vessels are also stored by MATBAL. The user may choose from several options for calculation methods (ash and mass normalization), data retrieval and storage, and the types of information printed. This report explains the subroutines, functions, and variables used in the MATBAL code and matches the code input with the printed output. A discussion of program execution explains the use of the input cards, options, and steps of execution. 42 figs.

    Purpose The study investigated the effects of FIFA 11+ and HarmoKnee, both being popular warm-up programs, on proprioception, and on the static and dynamic balance of professional male soccer players. Methods Under 21 year-old soccer players (n = 36) were divided randomly into 11+, HarmoKnee and control groups. The programs were performed for 2 months (24 sessions). Proprioception was measured bilaterally at 30°, 45° and 60° knee flexion using the Biodex Isokinetic Dynamometer. Static and dynamic balances were evaluated using the stork stand test and Star Excursion Balance Test (SEBT), respectively. Results The proprioception error of dominant leg significantly decreased from pre- to post-test by 2.8% and 1.7% in the 11+ group at 45° and 60° knee flexion, compared to 3% and 2.1% in the HarmoKnee group. The largest joint positioning error was in the non-dominant leg at 30° knee flexion (mean error value = 5.047), (pproprioception at 45° and 60° knee flexion as well as static and dynamic balance in professional male soccer players. Data from this research may be helpful in encouraging coaches or trainers to implement the two warm-up programs in their soccer teams. PMID:23251579

  19. Exercise-Based Fall Prevention in the Elderly: What About Agility?

    Science.gov (United States)

    Donath, Lars; van Dieën, Jaap; Faude, Oliver

    2016-02-01

    Annually, one in three seniors aged over 65 years fall. Balance and strength training can reduce neuromuscular fall risk factors and fall rates. Besides conventional balance and strength training, explosive or high-velocity strength training, eccentric exercises, perturbation-based balance training, trunk strength, and trunk control have also been emphasized. In contrast, aerobic exercise has to date not been included in fall-prevention studies. However, well-developed endurance capacity might attenuate fatigue-induced declines in postural control in sports-related or general activities of daily living. Physical performance indices, such as balance, strength, and endurance, are generally addressed independently in exercise guidelines. This approach seems time consuming and may impede integrative training of sensorimotor, neuromuscular, and cardiocirculatory functions required to deal with balance-threatening situations in the elderly. An agility-based conceptual training framework comprising perception and decision making (e.g., visual scanning, pattern recognition, anticipation) and changes of direction (e.g., sudden starts, stops and turns; reactive control; concentric and eccentric contractions) might enable an integrative neuromuscular, cardiocirculatory, and cognitive training. The present paper aims to provide a scientific sketch of how to build such an integrated modular training approach, allowing adaptation of intensity, complexity, and cognitive challenge of the agility tasks to the participant's capacity. Subsequent research should address the (1) link between agility and fall risk factors as well as fall rates, (2) benefit-risk ratios of the proposed approach, (3) psychosocial aspects of agility training (e.g., motivation), and (4) logistical requirements (e.g., equipment needed).

  1. Software ``Best'' Practices: Agile Deconstructed

    Science.gov (United States)

    Fraser, Steven

    Software “best” practices depend entirely on context - in terms of the problem domain, the system constructed, the software designers, and the “customers” ultimately deriving value from the system. Agile practices no longer have the luxury of “choosing” small non-mission critical projects with co-located teams. Project stakeholders are selecting and adapting practices based on a combina tion of interest, need and staffing. For example, growing product portfolios through a merger or the acquisition of a company exposes legacy systems to new staff, new software integration challenges, and new ideas. Innovation in communications (tools and processes) to span the growth and contraction of both information and organizations, while managing the adoption of changing software practices, is imperative for success. Traditional web-based tools such as web pages, document libraries, and forums are not suf ficient. A blend of tweeting, blogs, wikis, instant messaging, web-based confer encing, and telepresence creates a new dimension of communication “best” practices.

  2. Software Solutions for Agile Business

    Directory of Open Access Journals (Sweden)

    Viorel LUPU

    2006-01-01

    Full Text Available Businesses, like people, are continuously evolving and as such face rapid and continual change. As markets and customer needs evolve, enterprises must respond with new ways to attract and retain customers and partners, increase operational efficiency, and achieve greater visibility into their business processes. IT staff see business processes through the lens of the low-level parts of the flow, rather than at the business level. As a result, they aren't capable of implementing the processes so that they will meet continuously changing business requirements, thus impeding business agility. Business users are increasingly demanding that they have control over their own business processes - and so, are requiring systems that put control of the flow and logic into their hands, not those of IT. An Enterprise Service Bus based on a Service Oriented Architecture could be a solution and tie together the notions of service oriented process, service oriented integration and event-driven, message based interaction into a single environment that enables users to combine their assets and information from multiple points of view.

    This preliminary study examined the effect of a 10-wk traditional Greek dance program on static and dynamic balance indices in healthy elderly adults. Twenty-six community-dwelling older adults were randomly assigned to either an intervention group who took supervised Greek traditional dance classes for 10 wk (1 hr, 2 sessions/week, n = 14), or a control group (n = 12). Balance was assessed pre- and postintervention by recording the center-of-pressure (COP) variations and trunk kinematics during performance of the Sharpened-Romberg test, 1-leg (OL) stance, and dynamic weight shifting (WS). After practice, the dance group significantly decreased COP displacement and trunk sway in OL stance. A significant increase in the range of trunk rotation was noted during performance of dynamic WS in the sagittal and frontal planes. These findings support the use of traditional dance as an effective means of physical activity for improving static and dynamic balance control in the elderly.

    The purpose of this study was to investigate the effect of a 12-month Balance Training Program on balance, mobility and falling frequency in women with osteoporosis. Sixty-six consecutive elderly women were selected from the Osteometabolic Disease Outpatient Clinic and randomized into 2 groups: the 'Intervention', submitted for balance training; and the 'Control', without intervention. Balance, mobility and falling frequency were evaluated before and at the end of the trial, using the Berg Balance Scale (BBS), the Clinical Test Sensory Interaction Balance (CTSIB) and the Timed "Up & Go" Test (TUGT). Intervention used techniques to improve balance consisting of a 1-hour session each week and a home-based exercise program. Sixty women completed the study and were analyzed. The BBS difference was significant higher in the Intervention group compared to Control (5.5 +/- 5.67 vs -0.5 +/- 4.88 score, pmobility and falling frequency in elderly women with osteoporosis.

    Ankle sprains are the most common musculoskeletal injuries that occur in athletes, and they have a profound impact on health care costs and resources. A balance training program can reduce the risk of ankle sprains in high school athletes. Randomized controlled clinical trial; Level of evidence, 1. Seven hundred and sixty-five high school soccer and basketball players (523 girls and 242 boys) were randomly assigned to either an intervention group (27 teams, 373 subjects) that participated in a balance training program or to a control group (28 teams, 392 subjects) that performed only standard conditioning exercises. On-site athletic trainers recorded athlete exposures and sprains. The rate of ankle sprains was significantly lower for subjects in the intervention group (6.1%, 1.13 of 1000 exposures vs 9.9%, 1.87 of 1000 exposures; P = .04). Athletes with a history of an ankle sprain had a 2-fold increased risk of sustaining a sprain (risk ratio, 2.14), whereas athletes who performed the intervention program decreased their risk of a sprain by one half (risk ratio, 0.56). The ankle sprain rate for athletes without previous sprains was 4.3% in the intervention group and 7.7% in the control group, but this difference was not significant (P = .059). A balance training program will significantly reduce the risk of ankle sprains in high school soccer and basketball players.

Data from this research may be helpful in encouraging coaches or trainers to implement the two warm-up programs in their soccer teams.

  7. Fighter agility metrics. M.S. Thesis

    Liefer, Randall K.

    1990-01-01

    Fighter flying qualities and combat capabilities are currently measured and compared in terms relating to vehicle energy, angular rates and sustained acceleration. Criteria based on these measurable quantities have evolved over the past several decades and are routinely used to design aircraft structures, aerodynamics, propulsion and control systems. While these criteria, or metrics, have the advantage of being well understood, easily verified and repeatable during test, they tend to measure the steady state capability of the aircraft and not its ability to transition quickly from one state to another. Proposed new metrics to assess fighter aircraft agility are collected and analyzed. A framework for classification of these new agility metrics is developed and applied. A complete set of transient agility metrics is evaluated with a high fidelity, nonlinear F-18 simulation. Test techniques and data reduction methods are proposed. A method of providing cuing information to the pilot during flight test is discussed. The sensitivity of longitudinal and lateral agility metrics to deviations from the pilot cues is studied in detail. The metrics are shown to be largely insensitive to reasonable deviations from the nominal test pilot commands. Instrumentation required to quantify agility via flight test is also considered. With one exception, each of the proposed new metrics may be measured with instrumentation currently available.

    2016-11-01

    The present study aimed to quantify the demand of seven generic, closed agility drills. Twenty males with experience in invasion sports volunteered to participate in this study. They performed seven, closed agility drills over a standardised 30-m distance. Physical demand measures of peak velocity, total foot contacts, peak impacts, completion time, and maximum heart rate were obtained via the use of wearable sensor technologies. A subjective rating of perceived exertion (RPE) was also obtained. All measures, with the exception of maximum heart rates and RPE were able to delineate drills in terms of physical and physiological demand. The findings of this study exemplify the differences in demand of agility-type movements. Drill demand was dictated by the type of agility movement initiated with the increase in repetitiveness of a given movement type also contributing to increased demand. Findings from this study suggest agility drills can be manipulated to vary physical and physiological demand. This allows for the optimal application of training principles such as overload, progression, and periodisation.

    Balance and postural control (PC) disorders are frequent motor disorder symptoms associated with multiple sclerosis (MS). To demonstrate the potential improvements in balance and PC among patients with MS who complete a virtual reality telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. 50 patients was recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received telerehabilitation treatment using the Xbox 360® console monitored via videoconference. Experimental group attended 40 sessions, four sessions per week (20 min per session). The treatment schedule lasted 10 weeks for both groups. A computerised dynamic posturography and clinical outcomes (Berg Balance and Tinettti scales) were used at baseline and at the end of the treatment. Results showed an improvement over general balance in both groups. Visual preference, the contribution of vestibular information, mean response time and Tinetti test yielded significant differences in the experimental group. An ANOVA revealed significant between-group post-treatment differences in the composite equilibrium score, Berg and Tinetti scales in the experimental group. We suggest that our virtual reality program enables anticipatory PC and response mechanisms and might serve as a successful therapeutic alternative in situations in which conventional therapy is not readily available.

    Full Text Available Agile project management methodologies, tools and techniques have been becoming more and more popular among Russian and foreign software companies. Though the agile software project management methodologies appear to be more flexible and sound alternative to traditional project management approaches, the practice of agile project management implementation needs more research. The article presents the research on the practical results of agile project management implementation in Russian software engineering companies. The survey-based study covers 8 companies and 35 their projects managed with the help of agile methodologies. In contrast to some optimistic researchers of agile practices, the research findings show that in the investigated projects agile project management led to the deterioration of cost and schedule performance. However, the quality, both perceived by clients and assessed by internal technical analysts, improved after the implementation of agile software project management practices.

    Full Text Available In the 3rd millennium economy, defined by globalization and continuous reduction of natural resources, the economic organization becomes the main actor in the phenomenon of transfor-mation and adaptation to new conditions. Even more, the economic environment, which is closely related to the social environment, undergoes complex metamorphoses, especially in the management area. In this dynamic and complex social and environmental context, the econom-ic organization must possess the ability to adapt, becoming a flexible and agile answer to new market opportunities. Considering the spectacular evolution of information and communica-tions technology, one of the solutions to ensure organization agility is cloud computing. Just like the development of any science requires adaptation to theories and instruments specific to other fields, a cloud computing paradigm for the agile organization must appeal to models from management, cybernetics, mathematics, structuralism and information theory (or information systems theory.

    2016-06-01

    Full Text Available Background: Authors in their contribution point to the differences in the methods of measurement of agility in the practice. Based on the experience of coaches as well as on their own experience have come to the conclusion that the Illinois Agility Test, which has long been used for the testing of agility in fact does not measure perception abilities and decision-making processes, since motor activity performed during the testing procedure represents a closed skill, where the only task of the tested person is to accelerate, decelerate and change the direction of running, while the task is known in advance. On the contrary, some authors recommend the testing of agility using apparatuses measuring selective reaction, such as Fitro Agility Check. Objective: The aim of the research was to find out differences in the performance of players from the point of view of sport specialization and also to assess the relationship between the performance of players in two agility tests (Illinois Agility Test, measuring the ability of simple reaction, acceleration, deceleration and changes of movement direction, as well as Fitro Agility Check, measuring the above mentioned processes plus the ones of perception and decision-making. Methods: The sample comprised basketball (G1, volleyball (G2 and soccer (G3 players (N = 55 boys, Mage = 15.78 years, age range = 14-17 years from sport clubs in Slovakia.

    Full Text Available Abstract Background Previous research investigating exercise as a means of falls prevention in older adults has shown mixed results. Lack of specificity of the intervention may be an important factor contributing to negative results. Change-in-support (CIS balance reactions, which involve very rapid stepping or grasping movements of the limbs, play a critical role in preventing falls; hence, a training program that improves ability to execute effective CIS reactions could potentially have a profound effect in reducing risk of falling. This paper describes: 1 the development of a perturbation-based balance training program that targets specific previously-reported age-related impairments in CIS reactions, and 2 a study protocol to evaluate the efficacy of this new training program. Methods/Design The training program involves use of unpredictable, multi-directional moving-platform perturbations to evoke stepping and grasping reactions. Perturbation magnitude is gradually increased over the course of the 6-week program, and concurrent cognitive and movement tasks are included during later sessions. The program was developed in accordance with well-established principles of motor learning, such as individualisation, specificity, overload, adaptation-progression and variability. Specific goals are to reduce the frequency of multiple-step responses, reduce the frequency of collisions between the stepping foot and stance leg, and increase the speed of grasping reactions. A randomised control trial will be performed to evaluate the efficacy of the training program. A total of 30 community-dwelling older adults (age 64–80 with a recent history of instability or falling will be assigned to either the perturbation-based training or a control group (flexibility/relaxation training, using a stratified randomisation that controls for gender, age and baseline stepping/grasping performance. CIS reactions will be tested immediately before and after the six

    Serpell, Benjamin G; Young, Warren B; Ford, Matthew

    2011-05-01

    Agility is an open motor skill; requiring change of direction speed (CODS) and perceptual and decision-making ability. The aim of this study was to determine whether the perceptual and decision-making component of agility can be trained. Fifteen rugby league players were tested on a sport-specific reactive agility test (RAT) and a CODS test. Players were then allocated to a training group (n = 8) or a nontraining group (n = 7). The training group underwent 3 weeks of reactive agility training that was designed to enhance perceptual and decision-making ability. After 3 weeks, all players were tested again. The training group's mean reactive agility time was 1.92 ± 0.17 seconds preintervention and 1.66 ± 0.14 seconds postintervention. The nontraining group's mean reactive agility time was 1.89 ± 0.16 and 1.87 ± 0.15 seconds, respectively. Mean CODS time for the training group was 1.64 ± 0.15 seconds preintervention and 1.66 ± 0.14 seconds postintervention. The nontraining group's mean CODS time was 1.61 ± 0.12 and 1.62 ± 0.12 seconds. Mean perception and response time for the training group, measured on the RAT, was 0.33 ± 0.33 seconds preintervention and 0.04 ± 0.22 seconds postintervention. The nontraining group's values were 0.34 ± 0.20 and 0.27 ± 0.28 seconds, respectively (results are ±σ). Differences in mean reactive agility time and perception and response time from pre to postintervention for the training group were statistically significant, as were differences in those values between the training and nontraining group post intervention. All other comparisons were not. Results from this study suggest that the perceptual and decision-making components of agility are trainable. Coaches should incorporate some open motor skills training in their programs when training agility.

    The aim of this study was to compare the effects of in-season combined resisted agility and repeated sprint training with strength training on soccer players' agility, linear single sprint speed, vertical jump, repeated sprint ability (RSA), and aerobic capacity. Twenty well-trained elite female soccer players of age ± SD 19.4 ± 4.4 years volunteered to participate in this study. The participants were randomly assigned to either the agility and repeated sprint training group or to the strength training group. All the participants were tested before and after a 10-week specific conditioning program. The pretest and posttest were conducted on 3 separate days with 1 day of low-intensity training in between. Test day 1 consisted of squat jump (SJ), countermovement jump (CMJ), and RSA. Test day 2 consisted of a 40-m maximal linear sprint and an agility test, whereas a Beep test was conducted on test day 3 to assess aerobic capacity. The agility and repeated sprint training implemented in this study did not have a significant effect on agility, although there was a tendency for moderate improvements from 8.23 ± 0.32 to 8.06 ± 0.21 seconds (d = 0.8). There was a significant (p agility performance (d = -0.1). No between-group differences were observed. The outcome of this study indicates the importance of a well-planned program of conditioning that does not result in a decreased performance of the players, the great importance of strength and conditioning specialist in implementing the training program, and the importance of choosing the time of the year to implement such conditioning training programs. However, the fact that the present training program did not cause any decline in performance indicates that it is useful in maintaining the soccer players' physical performance during the competition period.

    SuperAGILE is a coded mask experiment based on silicon microstrip detectors. It operates in the 15 45 keV nominal energy range, providing crossed one-dimensional images of the X-ray sky with an on-axis angular resolution of 6 arcmin, over a field of view in excess of 1 sr. It was designed as the hard X-ray monitor of the AGILE space mission, a small satellite of the Italian Space Agency devoted to image the gamma-ray sky in the 30 MeV 50 GeV energy band. The AGILE mission was launched in a low-earth orbit on 23rd April 2007. In this paper we describe the SuperAGILE experiment, its construction and test processes, and its performance before flight, based on the on-ground test and calibrations.

    Resistance training programs have been found to improve muscle strength, physical function, and depressive symptoms in middle-aged and older adults. These programs have typically been provided in clinical facilities, health clubs, and senior centers, which may be inconvenient and/or cost prohibitive for some older adults. The purpose of this study was to investigate the effectiveness of an automated telemedicine intervention that provides real-time guidance and monitoring of resistance training in the home. A randomized clinical trial in 103 middle-aged or older participants. Participants were assigned to use of a theory-driven interactive voice response system designed to promote resistance training (Telephone-Linked Computer-based Long-term Interactive Fitness Trainer; n = 52) or to an attention control (n = 51) for a period of 12 months. Measurements of muscle strength, balance, walk distance, and mood were obtained at baseline, 3, 6, and 12 months. We observed increased strength, improved balance, and fewer depressive symptoms in the intervention group than in the control group. Using generalized estimating equations modeling, group differences were statistically significant for knee flexion strength (p = .035), single-leg stance time (p = .029), and Beck Depression Inventory (p = .030). This computer-based telecommunications exercise intervention led to improvements in participants' strength, balance, and depressive symptoms. Because of their low cost and easy accessibility, computer-based interventions may be a cost-effective way of promoting exercise in the home.

    We examined whether a program combining cognitive-behavioural therapy (CBT), vestibular rehabilitation (VR) and psychoeducation is equally effective in improving psychometric measures in patients with dizziness independent of a balance deficit. Measures of patients with dizziness only (DO) were compared to those of patients also having a quantified balance deficit (QBD). 32 patients (23 female, 9 male) with persistent dizziness were analysed as 2 groups based on stance and gait balance control: those with QBD (pathological balance) or DO (normal balance). Dizziness Handicap Inventory (DHI) and Brief Symptom Inventory (BSI) questionnaires were used pre- and post-therapy to assess psychometric measures. Patients then received the same combination therapy in a group setting. The QBD group mean age was 60.6, SD 8.3, and DO group mean age 44.8, SD 12.1, years. Pre-therapy, questionnaire scores were pathological but not different between groups. Balance improved significantly for the QBD group (p=0.003) but not for the DO group. DHI and BSI scores improved significantly in the DO group (0.001VR, and psychoeducation improves psychological measures in DO patients but not significantly in QBD patients, despite their balance control improving to near normal. Possibly, greater focus on phobic anxiety during the group therapy program would have improved psychological measures of QBD patient. Copyright © 2017 Elsevier Inc. All rights reserved.

    Three-dimensional kinematic analysis examined agility running technique during pre-planned and reactive performance conditions specific to attacking ball carries in rugby union. The variation to running technique of 8 highly trained rugby union players was compared between agility conditions (pre-planned and reactive) and also agility performance speeds (fast, moderate and slow). Kinematic measures were used to determine the velocity of the centre of mass (COM) in the anteroposterior (running speed) and mediolateral (lateral movement speed) planes. The position of foot-strike and toe-off was also examined for the step prior to the agility side- step (pre-change of direction phase) and then the side-step (change of direction phase). This study demonstrated that less lateral movement speed towards the intended direction change occurred during reactive compared to pre-planned conditions at pre-change of direction (0.08 ± 0.28 m·s(-1) and 0.42 ± 0.25 m·s(-1), respectively) and change of direction foot-strikes (0.25 ± 0.42 m·s(-1) and 0.69 ± 0.43 m·s(-1), respectively). Less lateral movement speed during reactive conditions was associated with greater lateral foot displacement (44.52 ± 6.10% leg length) at the change of direction step compared to pre-planned conditions (41.35 ± 5.85%). Importantly, the anticipation abilities during reactive conditions provided a means to differentiate between speeds of agility performance, with faster performances displaying greater lateral movement speed at the change of direction foot- strike (0.52 ± 0.34 m·s(-1)) compared to moderate (0.20 ± 0.37 m·s(-1)) and slow (-0.08 ± 0.31 m·s(-1)). The changes to running technique during reactive conditions highlight the need to incorporate decision-making in rugby union agility programs. Key pointsChanges to running technique occur when required to make a decision.Fast agility performers use different stepping strategies in reactive conditions.Decision-making must be

    Full Text Available Background/Aim/Purpose: A commonly implemented software process improvement framework is the capability maturity model integrated (CMMI. Existing literature indicates higher levels of CMMI maturity could result in a loss of agility due to its organizational focus. To maintain agility, research has focussed attention on agile maturity models. The objective of this paper is to find the common research themes and conclusions in agile maturity model research. Methodology: This research adopts a systematic approach to agile maturity model research, using Google Scholar, Science Direct, and IEEE Xplore as sources. In total 531 articles were initially found matching the search criteria, which was filtered to 39 articles by applying specific exclusion criteria. Contribution:: The article highlights the trends in agile maturity model research, specifically bringing to light the lack of research providing validation of such models. Findings: Two major themes emerge, being the coexistence of agile and CMMI and the development of agile principle based maturity models. The research trend indicates an increase in agile maturity model articles, particularly in the latter half of the last decade, with concentrations of research coinciding with version updates of CMMI. While there is general consensus around higher CMMI maturity levels being incompatible with true agility, there is evidence of the two coexisting when agile is introduced into already highly matured environments. Future Research:\tFuture research direction for this topic should include how to attain higher levels of CMMI maturity using only agile methods, how governance is addressed in agile environments, and whether existing agile maturity models relate to improved project success.

    Hypothalamic neuropeptides play essential roles in regulating energy and body weight balance. Energy imbalance and obesity have been linked to hypothalamic signaling defects in regulating neuropeptide genes; however, it is unknown whether dysregulation of neuropeptide exocytosis could be critically involved. This study discovered that synaptotagmin-4, an atypical modulator of synaptic exocytosis, is expressed most abundantly in oxytocin neurons of the hypothalamus. Synaptotagmin-4 negatively regulates oxytocin exocytosis, and dietary obesity is associated with increased vesicle binding of synaptotagmin-4 and thus enhanced negative regulation of oxytocin release. Overexpressing synaptotagmin-4 in hypothalamic oxytocin neurons and centrally antagonizing oxytocin in mice are similarly obesogenic. Synaptotagmin-4 inhibition prevents against dietary obesity by normalizing oxytocin release and energy balance under chronic nutritional excess. In conclusion, the negative regulation of synaptotagmin-4 on oxytocin release represents a hypothalamic basis of neuropeptide exocytosis in controlling obesity and related diseases. PMID:21315262

    Project management in modern IT companies is often based on agile methodologies which have several advantages compared to traditional methodologies such is waterfall. Having in mind that clients sometimes change project during development it is crucial for an IT company to choose carefully which methodology is going to implement and is it going to be mostly based on one or is it going got be combination of several. There are several modern and often used methodologies but among those Scrum, Kanban and XP programming are usually the most common. Sometimes companies use mostly tools and procedures from one but quite often they use some of the combination of those methodologies. Having in mind that those methodologies are just a framework they allow companies to adapt it for their specific projects as well as for other limitations. These methodologies are in limited usage Bosnia but more and more IT companies are starting to use agile methodologies because it is practice and common not just for their clients abroad but also starting to be the only option in order to deliver quality product on time. However it is always challenging which methodology or combination of several companies should implement and how to connect it to its own project, organizational framework and HR management. This paper presents one case study based on local IT start up and delivers solution based on theoretical framework and practical limitations that case company has.

    This study investigated the effects of the A Matter of Balance (MOB) program on falls and physical risk factors of falling among community-dwelling older adults living in Tampa, Florida, in 2013. A total of 110 adults (52 MOB, 58 comparison) were enrolled in this prospective cohort study. Data on falls, physical risk of falling, and other known risk factors of falling were collected at baseline and at the end of the program. Multivariate analysis of covariance with repeated measures and logistic regressions were used to investigate the effects of this program. Participants in the MOB group were less likely to have had a fall and had significant improvements in their physical risk of falling compared with adults in the comparison group. No significant effects of the MOB program on recurrent falls or the number of falls reported were found. This study contributes to our understanding of the MOB program and its effectiveness in reducing falls and the physical risk of falling among older adults. The findings support extended use of this program to reduce falls and physical risk of falling among older adults.

    During our tests, we found a wide range of abilities between participants. Whilst there is a correlation between age and balance (Figure 5, there were outliers, certain participants had poor balance in spite of being in the younger cohort, and some older participants tested very well for their age. Our quantitative research indicates that this difference is due to the difference in activity histories over the life time of an individual. A 25 year old participant commented “Your app has shown me how awful my balance is! Not looking forward to being older and we have osteoporosis in my family! Lots of broken bones for me! O dear!!” This lead us to think that what seems like a straightforward act (standing on one leg for a period of 15 seconds , can actually be demotivating for individuals. In order to keep the participants engaged, we needed to incorporate easier stances, which while challenging, were not a blockade to improvement. This would allow an individual to start at an ability appropriate level and build up to better balance in tiny increments. Hence we have created a training programme (Figure 6 which can computationally determine the ability of the individual during the on boarding process. Once the current postural sway id determined, the individual is assigned to one of 3 Stances ( Semi Tandem for Beginners, Tandem for Intermediate, Uni-pedal Standing for Advanced. Each stance has 4 levels of varying lengths. ( typically 15s, 30s, 45s, 60s An individual could be assigned to start training at Stance 1, Level 1 ( i.e. Semi tandem for 15 sec and gradually build up-to 60 sec over the course of 36 sessions, at the end of which the ‘wobble reduction’ would be used a measure to determine whether they were ready to pass on to the next level. We have added gamification elements in the form of giving meaningful tips, avoiding negative feedback, simplifying the interface by removing numbers and of-course, medals and celebration screens (Figure 7.

To investigate the effects of two post-acute supervised proprioceptive training programs in individuals with ankle sprain. Participants were recruited from a physiotherapy center for ankle sprain rehabilitation. In a pre-post treatment, blinded-assessor design, 22 individuals were randomly allocated to a balance or a proprioceptive neuromuscular facilitation (PNF) group. Both groups received 10 rehabilitation sessions, within a six-week period. Dorsiflexion range of motion (ROM), pain, functional and balance performance were assessed at baseline, at the end of training and eight weeks after training. Follow-up data were provided for 20 individuals. Eight weeks after training, statistically significant (pfunctional performance measures for both balance and PNF groups. Eight weeks after training, significant (pfunctional performance in individuals with sprain. Balance programs are also recommended for pain relief.

    Aging is usually accompanied with deterioration of physical abilities, such as muscular strength, sensory sensitivity, and functional capacity. Recently, intervention methods with virtual reality have been introduced, providing an enjoyable therapy for elderly. The aim of this study was to investigate whether a 3-D virtual reality kayak program could improve the cognitive function, muscle strength, and balance of community-dwelling elderly. Importantly, kayaking involves most of the upper body musculature and needs the balance control. Seventy-two participants were randomly allocated into the kayak program group (n = 36) and the control group (n = 36). The two groups were well matched with respect to general characteristics at baseline. The participants in both groups performed a conventional exercise program for 30 min, and then the 3-D virtual reality kayak program was performed in the kayak program group for 20 min, two times a week for 6 weeks. Cognitive function was measured using the Montreal Cognitive Assessment. Muscle strength was measured using the arm curl and handgrip strength tests. Standing and sitting balance was measured using the Good Balance system. The post-test was performed in the same manner as the pre-test; the overall outcomes such as cognitive function (p kayak program group compared to the control group. We propose that the 3-D virtual reality kayak program is a promising intervention method for improving the cognitive function, muscle strength, and balance of elderly.

    Full Text Available Balance dysfunction (BD in Parkinson’s disease (PD is a disabling symptom, difficult to treat and predisposing to falls. The dopaminergic drugs or deep brain stimulation does not always provide significant improvements of BD and rehabilitative approaches have also failed to restore this condition. In this study, we investigated the suitability of quantitative posturographic indicators to early identify patients that could develop disabling BD. Parkinsonian patients not complaining of a subjective BD and controls were tested using a posturographic platform (PP with open eyes (OE and performing a simple cognitive task [counting (OEC]. We found that patients show higher values of total standard deviation (SD of body sway and along the medio-lateral (ML axis during OE condition. Furthermore, total and ML SD of body sway during OE condition and total SD of body sway with OEC were higher than controls also in a subgroup of patients with normal Berg Balance Scale. We conclude that BD in Parkinsonian patients can be discovered before its appearance using a PP and that these data may allow developing specific rehabilitative treatment to prevent or delay their onset.

    Context: Improving neuromuscular control of hamstrings muscles might have implications for decreasing anterior cruciate ligament injuries in females. Objective: To examine the effects of a 6-week agility training program on quadriceps and hamstrings muscle activation, knee flexion angles, and peak vertical ground reaction force. Design: Prospective, randomized clinical research trial. Setting: Sports medicine research laboratory. Patients or Other Participants: Thirty female intramural basketball players with no history of knee injury (age  =  21.07 ± 2.82 years, height  =  171.27 ± 4.66 cm, mass  =  66.36 ± 7.41 kg). Intervention(s): Participants were assigned to an agility training group or a control group that did not participate in agility training. Participants in the agility training group trained 4 times per week for 6 weeks. Main Outcome Measure(s): We used surface electromyography to assess muscle activation for the rectus femoris, vastus medialis oblique, medial hamstrings, and lateral hamstrings for 50 milliseconds before initial ground contact and while the foot was in contact with the ground during a side-step pivot maneuver. Knee flexion angles (at initial ground contact, maximum knee flexion, knee flexion displacement) and peak vertical ground reaction force also were assessed during this maneuver. Results: Participants in the training group increased medial hamstrings activation during ground contact after the 6-week agility training program. Both groups decreased their vastus medialis oblique muscle activation during ground contact. Knee flexion angles and peak vertical ground reaction force did not change for either group. Conclusions: Agility training improved medial hamstrings activity in female intramural basketball players during a side-step pivot maneuver. Agility training that improves hamstrings activity might have implications for reducing anterior cruciate ligament sprain injury associated with side-step pivots. PMID

    To maximize efficiency and flexibility in Mission Operations System (MOS) design, we are evolving principles from agile and lean methods for software, to the complete mission system. This allows for reduced operational risk at reduced cost, and achieves a more effective design through early integration of operations into mission system engineering and flight system design. The core principles are assessment of capability through demonstration, risk reduction through targeted experiments, early test and deployment, and maturation of processes and tools through use.

    Full Text Available Global health practitioners may feel frustration that current models of global health research, delivery, and implementation are overly focused on specific interventions, slow to provide health services in the field, and relatively ill-equipped to adapt to local contexts. Adapting design principles from the agile software development movement, we propose an analogous approach to designing global health programs that emphasizes tight integration between research and implementation, early involvement of ground-level health workers and program beneficiaries, and rapid cycles of iterative program improvement. Using examples from our own fieldwork, we illustrate the potential of ‘agile global health’ and reflect on the limitations, trade-offs, and implications of this approach.

  9. Architecture-Centric Methods and Agile Approaches

    Science.gov (United States)

    Babar, Muhammad Ali; Abrahamsson, Pekka

    Agile software development approaches have had significant impact on industrial software development practices. Despite becoming widely popular, there is an increasing perplexity about the role and importance of a system’s software architecture in agile approaches [1, 2]. Advocates of the vital role of architecture in achieving quality goals of large-scale-software-intensive-systems are skeptics of the scalability of any development approach that does not pay sufficient attention to architectural issues. However, the proponents of agile approaches usually perceive the upfront design and evaluation of architecture as being of less value to the customers of a system. According to them, for example, re-factoring can help fix most of the problems. Many experiences show that large-scale re-factoring often results in significant defects, which are very costly to address later in the development cycle. It is considered that re-factoring is worthwhile as long as the high-level design is good enough to limit the need for large-scale re-factoring [1, 3, 4].

    Epidemiological data demonstrate the need for lower-extremity injury-prevention training. Neuromuscular-control (NMC) programs are immediately effective at minimizing lower-extremity injury risk and improving sport-related performance measures. Research investigating lasting effects after an injury-prevention program is limited. To determine whether dynamic balance, landing mechanics, and hamstring and quadriceps strength could be improved after a 6-wk NMC intervention and maintained for a season. Prospective case series. Controlled laboratory. 11 Division I women's basketball players (age 19.40 ± 1.35 y, height 178.05 ± 7.52 cm, mass 72.86 ± 10.70 kg). Subjects underwent testing 3 times, completing the Star Excursion Balance Test (SEBT), Landing Error Scoring System (LESS), and isometric strength testing for the hamstrings and quadriceps muscles. Pretest and posttest 1 occurred immediately before and after the intervention, respectively, and posttest 2 at the end of the competitive season, 9 mo after posttest 1. Subjects participated in eighteen 30-min plyometric and NMC-training sessions over a 6-wk period. The normalized SEBT composite score, normalized peak isometric hamstrings:quadriceps (H:Q) ratio, and the LESS total score. The mean composite reach significantly improved over time (F2,10 = 6.96, P = .005) where both posttest scores were significantly higher than pretest (70.41% ± 4.08%) (posttest 1 73.48% ± 4.19%, t10 = -3.11, P = .011) and posttest 2 (74.2% ± 4.77%, t10 = -3.78, P = .004). LESS scores significantly improved over time (F2,10 = 6.29, P = .009). The pretest LESS score (7.30 ± 3.40) was higher than posttest 1 (4.9 ± 1.20, t10 = 2.71, P = .024) and posttest 2 (5.44 ± 1.83, t10 = 2.58, P = .030). There were no statistically significant differences (P > .05) over time for the H:Q ratio when averaging both legs (F2,10 = 0.83, P = .45). A 6-wk NMC program improved landing mechanics and dynamic balance over a 9-mo period in women

  13. On the importance of agile communication skills in BPM education: Design principles for international seminars

    Full Text Available Business Process Management (BPM has evolved as an integrated management discipline that aims to enable organizations to continuously innovate and improve their operations. BPM experts are exposed to communication processes involving people from various backgrounds (e.g., various business areas, fields of expertise, and cultures. Research in applied linguistics has shown that it is difficult to plan for constellations of such communication processes; thus, agile communication skills are vital for successful business communication. Teaching programs for BPM, however, do not account for these skills. Rather, they mainly address methods for the analysis, implementation, and management of business processes. As a result, graduates—though they may be technically and methodologically apt—face unexpected challenges due to communication deficiencies in BPM projects. BPM research has shown that deficiencies in communication are in fact among the most frequent reasons for project failure. In this paper, we present a course setting to teach agile communication skills in BPM education. The approach is informed by literature on BPM education as well as theories from virtual collaboration education. We have evaluated it in an international virtual seminar involving seven European universities. We argue for the importance of agile communication skills in BPM education. In addition, we present design principles for courses to teach agile communication skills that can be applied by fellow academics.

  14. Supply chain network design problem for a new market opportunity in an agile manufacturing system

    2012-08-01

    The characteristics of today's competitive environment, such as the speed with which products are designed, manufactured, and distributed, and the need for higher responsiveness and lower operational cost, are forcing companies to search for innovative ways to do business. The concept of agile manufacturing has been proposed in response to these challenges for companies. This paper copes with the strategic and tactical level decisions in agile supply chain network design. An efficient mixed-integer linear programming model that is able to consider the key characteristics of agile supply chain such as direct shipments, outsourcing, different transportation modes, discount, alliance (process and information integration) between opened facilities, and maximum waiting time of customers for deliveries is developed. In addition, in the proposed model, the capacity of facilities is determined as decision variables, which are often assumed to be fixed. Computational results illustrate that the proposed model can be applied as a power tool in agile supply chain network design as well as in the integration of strategic decisions with tactical decisions.

    2014-09-01

    Full Text Available Background: Data on agility skills in different populations using pre-planned, change of direction speed tests have previously been reported. However, there are no available data on the agility times of athletes specializing in different sports obtained from Reactive agility tests. Objective: The study compares agility time in groups of athletes of different sports where agility is one of the limiting factors of performance. Methods: Altogether 282 athletes of 14 sport specializations performed the Agility test. Their task was to touch, as fast as possible, with either the left or the right foot, one of four mats located outside each of the four corners of a 0.8 m square. The mats had to be touched in accordance with the location of a stimulus in one of the corners of a screen. The test consisted of 60 visual stimuli with random generation of their location on the screen and a time of generation of 500 to 2,500 ms. The result was a sum of the 32 best agility times. Results: The Agility test has been found to be sensitive in distinguishing groups of athletes of different sport specializations. Table tennis players, badminton players, fencers, tae-kwon-do competitors and karate competitors showed the best agility times (< 350 ms, followed by ice-hockey, tennis, soccer, volleyball, basketball, and hockeyball players (350-400 ms, then aikidoists (400-450 ms, and finally judoists and wrestlers (450-500 ms. Conclusions: The best agility times are in athletes of racquet sports, followed by competitors of combat sports with reactions to visual stimuli, then players of ball sports, and finally competitors of combat sports with reactions to tactile stimuli. Since this is the first study testing agility skills using the Reactive agility test in athletes of different sport specializations, data obtained can be used for comparison of athletes within particular sports.

    The Swift Observatory will be launched in early 2004 to examine the dynamic process of gamma ray burst (GRB) events. The multi-wavelength Observatory will study the GRB afterglow characteristics, which will help to answer fundamental questions about both the structure and the evolution of the universe. The Swift Observatory Contamination Control Program has been developed to aid in ensuring the success of the on-orbit performance of two of the primary instruments: the Ultraviolet and Optical Telescope (UVOT) and the X-Ray Telescope (XRT). During the design phase of the Observatory, the contamination control program evolved and trade studies were performed to assess the risk of contaminating the sensitive UVOT and XRT optics during both pre-launch testing and on-orbit operations, within the constraints of the overall program cost and schedule.

    Schizophrenia causes psychological difficulties (with positive and/or negative symptoms) as well as cognitive disabilities (attention, memory, executive functions and social cognition). Moreover, 40 to 60% of patients suffer from an excess of weight or obesity (due to bad eating habits, eating disorders or medication). All these difficulties impair their autonomy and their insertion into the society. In this context, setting-up a therapeutic tool, which may have cognitive benefits seems relevant. Thus, MODen is a therapeutic educational tool whose aim is to improve cognitive functions and the symptoms by using "nutritional balance" as an aid. In this treatment program, two therapists lead a group of 5 to 8 patients which group meets once a week during two to four hours for 16 weeks, divided in 4 cycles. The first three weeks of each cycle consists of theoretical instruction: patients talk about their eating habits, information is given about nutritional balance and preparation of meals. In the different cycles, flexibility, planning, memory and attention are trained. For instance, the work on categorisation of foods and nutritional balance allow enhancing flexibility abilities. Writing down the lists of different ingredients needed for one week's meals and preparation of meals train planning abilities. MODen also takes into account ecological issues such as the limited budget of patients to do their shopping (this budget is around 4 euros per meal in France). The budget is also linked to planning abilities and reasoning. Finally, during the last session of each cycle the group prepares a meal (from the shopping to cooking). This last session is all about sharing and social cognition abilities. By the end of the program, patients will have prepared four meals together. Also "homework" has to be done each week in order to facilitate memorisation of what has been learned during the last session and to prepare the beginning of the next session. In a pilot study with 8

    Full Text Available Abstract Background The effects of a regular and graduated walking program as a stand-alone intervention for individuals in long-term care are unclear. Exercise and fall prevention programs typically studied in long-term care settings tend to involve more than one exercise mode, such as a combination of balance, aerobic, strengthening, and flexibility exercises; and, measures do not always include mental health symptoms and behaviors, although these may be of even greater significance than physical outcomes. Methods/design We are randomly assigning residents of long-term care facilities into one of three intervention groups: (1 Usual Care Group - individuals receive care as usual within their long-term care unit; (2 Interpersonal Interaction Group - individuals receive a comparable amount of one-on-one stationary interpersonal interaction time with study personnel administering the walking program; and, (3 Walking Program Group – individuals participate in a supervised, progressive walking program five days per week, for up to half an hour per day. Assessments completed at baseline, 2 and 4 months during intervention, and 2 and 4 months post-intervention include: gait parameters using the GAITRite® computerized system, grip strength, the Berg Balance Scale, the Senior Fitness Test, the Older Adult Resource Services Physical Activities of Daily Living, the Geriatric Depression Scale Short Form, the Cornell Scale for Depression in Dementia, the Revised Memory and Behavior Problems Checklist, the Short Portable Mental Status Questionnaire, the Coloured Analogue Scale, pain assessment scales, and the number and nature of falls. Sophisticated data analytic procedures taking into account both the longitudinal nature of the data and the potential for missing data points due to attrition, will be employed. Discussion Residents in long-term care have a very high number of comorbidities including physical, mental health, and cognitive. The presence of

    Full Text Available Objective: This research is aimed to evaluate precisely a dynamic stability platform system to measure the center of gravity's sways around with fluctuations of cerebral spastic palsy children, before an after exercise therapy. Materials & Methods: Ten children with spastic diplegia cerebral palsy between 8 to15 years of age, wre participated in this quasi experimental (after – before study. Their mean weight and height were (30.8kg ± 5.7kg and (1.35m±0.09m respectively. Subjects underwent a 12 weeks of exercise therapy. A dynamic stability platform system (BIODEX was used to measure the center of gravity’s sway around the center of base of support (COBOS. The balance tests were repeated on stable, almost stable and unstable base of support as well as with and without shoes. Results: Findings showed that the mean sway of center of gravity of the cerebral palsy children was significantly decrease after exercise therapy by 0.2 degrees (P=0.001. The greatest improvement achieved on AP directions in all conditions. Wearing shoes resulted in a significant decrease on the body sway. Conclusion: Exercise therapy significantly improved body balance in CP children. The function of the proprioceptives of the hip and trunk can be improved by exercise therapy and therefore should be considered in rehabilitation program.

    Tango-dancing and walking programs are compared in nondemented seniors at risk for falls. Fallers (N = 30) age 62-91 were randomly assigned to a 10-wk (40 hr, 2 hr 2x/wk) tango class or walk group. The Activities-specific Balance Confidence (ABC) scale, sit-to-stand scores, and normal and fast walk were measured pre-, post-, and 1 month postintervention. Two-way repeated-measures ANOVAs indicated a significant main effect (p tango because of high baseline mean for the walk group. Clinical improvements measured using Established Populations for Epidemiologic Studies of the Elderly scoring were greater for the tango group. From these preliminary results it is suggested that although both interventions are effective activities for increasing strength and walk speed, tango might result in greater improvements than walking in balance skills and in walking speed in the 10-wk intervention. The study needs to be repeated with a greater sample size to determine the effectiveness of walking on fear of falling.

    Full Text Available It’s introduced Lean techniques in a Clinical Laboratory to improve the operability and the efficiency in continuous processes of analysis, failsafe systems, analysis of areas of value pursuit of zero defects and reduction of waste, and it promote continuous improvement in presented difficulties in adapting to the changing needs of the healthcare environment. Whereas it is necessary to incorporate certification and accreditation, note that the adaptability of the clinical laboratory to the changing needs of physicians in obtaining analytical information is reduced. The application of an agile methodology on analytical systems can provide a line of work that allows the incorporation of planning short work cycles on equips quickly with operational autonomy on the basis of demand and respecting the accreditation requirements and flexibility to ensure adequate performance as the intercomparison of results from the different units analytics, analytical quality and turnaround times. Between 2012 and 2014, a process of analysis and improvement was applied to circuits, a 5 s system, transportation of samples, inventory of reactive and samples, motion of personal and samples, reductions of waiting and delays, overproduction, over processing, and defects of results and reports. At last it seems necessary to apply the Agile methodology to adapt to the evolving necessities in time and the different origins of the samples. It’s have used modular systems where the modules of this study are programmed with immunoassay techniques and it has reduced the operative modules depending on the required activity, ensuring the goals of turnaround times, analytic quality, service, health care continuity, and keeping up with the ISO 15189 accreditation requirements. The results of applying the concept of Lean-Agile to a modular system allows us to reduce the associated costs to the seasonal variation of the health care demand and to adapt the system to the changes on

    The prevalence of obesity in adults and children has increased globally at an alarming rate. Mounting evidence from both epidemiological studies and animal models indicates that adult obesity and associated metabolic disorders can be programmed by intrauterine and early postnatal environment- a phenomenon known as “fetal programming of adult disease.” Data from nutritional intervention studies in animals including maternal under- and over-nutrition support the developmental origins of obesity and metabolic syndrome. The hypothalamic neuronal circuits located in the arcuate nucleus controlling appetite and energy expenditure are set early in life and are perturbed by maternal nutritional insults. In this review, we focus on the effects of maternal nutrition in programming permanent changes in these hypothalamic circuits, with experimental evidence from animal models of maternal under- and over-nutrition. We discuss the epigenetic modifications which regulate hypothalamic gene expression as potential molecular mechanisms linking maternal diet during pregnancy to the offspring's risk of obesity at a later age. Understanding these mechanisms in key metabolic genes may provide insights into the development of preventative intervention strategies. PMID:25954145

    2018-02-01

    Distributed Space Missions such as formation flight and constellations, are being recognized as important Earth Observation solutions to increase measurement samples over space and time. Cubesats are increasing in size (27U, ∼40 kg in development) with increasing capabilities to host imager payloads. Given the precise attitude control systems emerging in the commercial market, Cubesats now have the ability to slew and capture images within short notice. We propose a modular framework that combines orbital mechanics, attitude control and scheduling optimization to plan the time-varying, full-body orientation of agile Cubesats in a constellation such that they maximize the number of observed images and observation time, within the constraints of Cubesat hardware specifications. The attitude control strategy combines bang-bang and PD control, with constraints such as power consumption, response time, and stability factored into the optimality computations and a possible extension to PID control to account for disturbances. Schedule optimization is performed using dynamic programming with two levels of heuristics, verified and improved upon using mixed integer linear programming. The automated scheduler is expected to run on ground station resources and the resultant schedules uplinked to the satellites for execution, however it can be adapted for onboard scheduling, contingent on Cubesat hardware and software upgrades. The framework is generalizable over small steerable spacecraft, sensor specifications, imaging objectives and regions of interest, and is demonstrated using multiple 20 kg satellites in Low Earth Orbit for two case studies - rapid imaging of Landsat's land and coastal images and extended imaging of global, warm water coral reefs. The proposed algorithm captures up to 161% more Landsat images than nadir-pointing sensors with the same field of view, on a 2-satellite constellation over a 12-h simulation. Integer programming was able to verify that

    To compute a ratio between the estimated numbers of lives saved from breast cancer death and the number of women diagnosed with a breast cancer that never would have been diagnosed during the woman's lifetime had she not attended screening (epidemiologic over-diagnosis) in the Norwegian Breast Cancer Screening Program. The Norwegian Breast Cancer Screening Program invites women aged 50-69 to biennial mammographic screening. Results from published studies using individual level data from the programme for estimating breast cancer mortality and epidemiologic over-diagnosis comprised the basis for the ratio. The mortality reduction varied from 36.8% to 43% among screened women, while estimates on epidemiologic over-diagnosis ranged from 7% to 19.6%. We computed the average estimates for both values. The benefit-detriment ratio, number of lives saved, and number of women over-diagnosed were computed for different scenarios of reduction in breast cancer mortality and epidemiologic over-diagnosis. For every 10,000 biennially screened women, followed until age 79, we estimated that 53-61 (average 57) women were saved from breast cancer death, and 45-126 (average 82) were over-diagnosed. The benefit-detriment ratio using average estimates was 1:1.4, indicating that the programme saved about one life per 1-2 women with epidemiologic over-diagnosis. The benefit-detriment ratio estimates of the Norwegian Breast Cancer Screening Program, expressed as lives saved from breast cancer death and epidemiologic over-diagnosis, should be interpreted with care due to substantial uncertainties in the estimates, and the differences in the scale of values of the events compared. © The Author(s) 2016.

    [Purpose] To verify the effects of individual and group exercise programs on pain, balance, mobility and perceived benefits of rheumatoid arthritis patients (RA) with pain and foot deformities. [Subjects and Methods] Thirty patients with RA pain and foot deformity were allocated into two groups: G1: individual exercise program and G2: group exercise program. The variables analyzed were Numerical Rating Scale (NRS) for pain, Berg Balance Scale (BBS) for balance, Timed Up & Go Test (TUG) and Functional Reach (FR) for mobility, and Foot Health Status Questionnaire (FHSQ-Br) for perceived benefits. Both exercise programs consisted of functional rehabilitation exercises and self-care guidance aimed at reducing pain and improving balance and mobility. Intragroup comparisons of variables between A1 (pre-intervention) and A2 (post-intervention) were performed. [Results] Patients in both groups were similar in A1 (pre-intervention) in all the variables analyzed. Comparison between A1 and A2 for each variable showed improvement for G1 in the NRS, BBS, FR, TUG and in four out of ten domains of FHSQ-Br. G2 showed improvement in the NRS, BBS and eight out of ten domains of FHSQ-Br. [Conclusion] Both individual and group programs revealed benefits for patients with RA, however, group exercise programs showed better perception of benefits.

The variables analyzed were Numerical Rating Scale (NRS) for pain, Berg Balance Scale (BBS) for balance, Timed Up & Go Test (TUG) and Functional Reach (FR) for mobility, and Foot Health Status Questionnaire (FHSQ-Br) for perceived benefits. Both exercise programs consisted of functional rehabilitation exercises and self-care guidance aimed at reducing pain and improving balance and mobility. Intragroup comparisons of variables between A1 (pre-intervention) and A2 (post-intervention) were performed. [Results] Patients in both groups were similar in A1 (pre-intervention) in all the variables analyzed. Comparison between A1 and A2 for each variable showed improvement for G1 in the NRS, BBS, FR, TUG and in four out of ten domains of FHSQ-Br. G2 showed improvement in the NRS, BBS and eight out of ten domains of FHSQ-Br. [Conclusion] Both individual and group programs revealed benefits for patients with RA, however, group exercise programs showed better perception of benefits.

    Balance and resistance training can improve healthy older adults' balance and muscle strength. Delivering such exercise programs at home without supervision may facilitate participation for older adults because they do not have to leave their homes. To date, no systematic literature analysis has been conducted to determine if supervision affects the effectiveness of these programs to improve healthy older adults' balance and muscle strength/power. The objective of this systematic review and meta-analysis was to quantify the effectiveness of supervised vs. unsupervised balance and/or resistance training programs on measures of balance and muscle strength/power in healthy older adults. In addition, the impact of supervision on training-induced adaptive processes was evaluated in the form of dose-response relationships by analyzing randomized controlled trials that compared supervised with unsupervised trials. A computerized systematic literature search was performed in the electronic databases PubMed, Web of Science, and SportDiscus to detect articles examining the role of supervision in balance and/or resistance training in older adults. The initially identified 6041 articles were systematically screened. Studies were included if they examined balance and/or resistance training in adults aged ≥65 years with no relevant diseases and registered at least one behavioral balance (e.g., time during single leg stance) and/or muscle strength/power outcome (e.g., time for 5-Times-Chair-Rise-Test). Finally, 11 studies were eligible for inclusion in this meta-analysis. Weighted mean standardized mean differences between subjects (SMDbs) of supervised vs. unsupervised balance/resistance training studies were calculated. The included studies were coded for the following variables: number of participants, sex, age, number and type of interventions, type of balance/strength tests, and change (%) from pre- to post-intervention values. Additionally, we coded training according to

    Main stream industry software development practice has gone from a traditional waterfall process to agile iterative development that allows for fast response to customer inputs and produces higher quality software at lower cost. How can we, the space ops community, adopt state of the art software development practice, achieve greater productivity at lower cost, and maintain safe and effective space flight operations? At NASA Ames, we are developing Mission Control Technologies Software, in collaboration with Johnson Space Center (JSC) and, more recently, the Jet Propulsion Laboratory (JPL).

  5. Striking a Balance between Program Requirements and GT Principles: Writing a compromised GT proposal

    Directory of Open Access Journals (Sweden)

    Sherry L. Xie, Ph.D. Candidate

    2009-06-01

    Full Text Available Glaser’s term “compromised GT proposal” (2001, p.114 refers to the type of Grounded Theory (GT proposal that is written in order to conform to the requirements of a standardized qualitative research proposal. A GT proposal needs only to supply information on the area of interest, the data source and a statement of method to the effect that the researcher begin to collect, code and analyse the data and let the theory emerge. Thus, the proposal may only occupy “a page or two” (Glaser, 2001, p. 111. Whilst being consistent with the methodology, a GT proposal sometimes has to give way to the format specified by a PhD program or committee even though the format was not defined for a GT proposal and in some areas, conflicts with GT principles; for example, the format may require a literature review. This short paper reports on my experience of writing a compromised GT proposal as a first-time GT researcher. It describes how both Glaser’s advice on writing compromised GT research proposals and the characteristics of the substantive area of the proposed research were used to satisfy program requirements while still maintaining GT fundamentals.

    The purpose of this study was to evaluate the reliability and factorial validity of agility tests used in soccer. One hundred fifty (n = 150), elite, male, junior soccer players, members of the First Junior League Team, volunteered to participate in the study. The slalom test (ST) sprint 4 x 5 m (S4 x 5) and sprint 9-3-6-3-6-9 m with 180 degree turns (S180 degrees) tests had a greater reliability coefficient (alpha = 0.992, 0.979, and 0.976), whereas the within-subject variation ranged between 2.9 and 5.6%. The mentioned 6 agility tests resulted in the extraction of 2 significant components. The S4 x 5 test had the lowest correlation coefficient with the first component (r = 0.38), whereas the correlation coefficients of the other 5 agility tests were higher than 0.63. The T-test (TT) showed statistically significant differences between the defenders and midfielders (p agility tests used in this study, the SBF, TT, and S180 degrees are the most reliable and valid tests for estimating the agility of soccer players. According to the results of the study, the TT proved to be the most appropriate for estimating the agility of defenders, the SBF, and S180 degrees for estimating the agility of midfielders, whereas the S4 x 5 test can be used for estimating the agility of attackers.

    The introduction of software technology in a life-dependent environment requires the development team to execute a process that ensures a high level of software reliability and correctness. Despite their popularity, agile methods are generally assumed to be inappropriate as a process family in these environments due to their lack of emphasis on documentation, traceability, and other formal techniques. Agile methods, notably Scrum, favor empirical process control, or small constant adjustments in a tight feedback loop. This paper challenges the assumption that agile methods are inappropriate for safety-critical software development. Agile methods are flexible enough to encourage the rightamount of ceremony; therefore if safety-critical systems require greater emphasis on activities like formal specification and requirements management, then an agile process will include these as necessary activities. Furthermore, agile methods focus more on continuous process management and code-level quality than classic software engineering process models. We present our experiences on the image-guided surgical toolkit (IGSTK) project as a backdrop. IGSTK is an open source software project employing agile practices since 2004. We started with the assumption that a lighter process is better, focused on evolving code, and only adding process elements as the need arose. IGSTK has been adopted by teaching hospitals and research labs, and used for clinical trials. Agile methods have matured since the academic community suggested they are not suitable for safety-critical systems almost a decade ago, we present our experiences as a case study for renewing the discussion.

  12. Review: The placenta and developmental programming: balancing fetal nutrient demands with maternal resource allocation.

    Science.gov (United States)

    Burton, G J; Fowden, A L

    2012-02-01

    The placenta evolved to support development of the fetus, and so potentially plays a key role in the aetiology of developmental programming through its impact on nutrient transfer. Placental transport efficiency depends on a variety of parameters, including surface area for exchange, thickness of the interhaemal membrane and density of transporter proteins inserted into the trophoblast membranes. Here, we review recent studies that tested whether adaptations of placental efficiency are induced in the mouse placenta when maternal nutrient supply and fetal demand are manipulated experimentally. Naturally small placentas, and those exposed to maternal undernutrition, displayed structural changes indicative of accelerated maturation at E16, with enlargement of the labyrinth exchange zone at the expense of the endocrine junctional zone. These changes were associated with increased transport of a non-metabolisable amino acid analogue per gram of placenta, and expression of genes encoding specific System A transporters. Up-regulation of transporters was also observed when a mismatch between placental size and fetal demand was generated through genetic manipulation of the Igf2/H19 axis. Conversely, overgrowth of the placenta induced by deletion of H19 resulted in reduced transport capacity and expression of transporter genes. We conclude that under conditions when the maternal nutrient supply or placental size may be limiting for normal fetal growth, the placenta adapts so as to increase its transport capacity. Hence, it ameliorates the effects of environmental cues that would otherwise lead to more extensive developmental programming. The P0 transcript of Igf2 appears to be a strong candidate as a mediator of these adaptations in the mouse. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Custom SME applications for collaboration and workflow have become affordable when implemented as Web applications employing Agile methodologies. Security engineering is still difficult with Agile development, though: heavy-weight processes put the improvements of Agile development at risk. We propose Agile security engineering and increased end-user involvement to improve Agile development with respect to authorization policy development. To support the authorization policy development, we introduce a simple and readable authorization rules language implemented in a Ruby on Rails authorization plugin that is employed in a real-world SME collaboration and workflow application. Also, we report on early findings of the language’s use in authorization policy development with domain experts.

    Styrken ved agil projektledelse er hurtigheden og muligheden for at absorbere ændringer hurtigt gennem hele projektets løbetid, men der er naturligvis også nogle svagheder. Nogle af dem nævner jeg i artiklen, men derudover egner agil-formen sig ikke specielt godt til komplicerede projekter, hvor...... liv eller mange penge er på spil. Agil-formen er heller ikke velegnet til umotiverede medarbejdere, fordi de ikke har noget at bidrage med.

    Full Text Available The spectacular evolution of information and communications technology in the last two decades and the growing obvious chase of utopian maximization of profit by economic organizations have made an impact on various fields, including that of methodological instruments regarding the lifecycle of software development. We will speak about the necessity of organizational ability to adapt to continuously changing market conditions, which leads undoubtedly to acquiring functional flexibility and, in the end, of business agility. Also, the agility of a business (not only in software development is supported by the manifestation of agility on all three architectural levels: business, informational, technological. In this study we aim to identify the elements that impact on agility in developing software products, in a gradual approach, from the traditional waterfall model towards approaches like Scrumban. Additionally, we will understand the social dimension of using agile methodologies in software development projects and the main barriers in adopting such methodologies.

  16. A Case Study of Coordination in Distributed Agile Software Development

    Science.gov (United States)

    Hole, Steinar; Moe, Nils Brede

    Global Software Development (GSD) has gained significant popularity as an emerging paradigm. Companies also show interest in applying agile approaches in distributed development to combine the advantages of both approaches. However, in their most radical forms, agile and GSD can be placed in each end of a plan-based/agile spectrum because of how work is coordinated. We describe how three GSD projects applying agile methods coordinate their work. We found that trust is needed to reduce the need of standardization and direct supervision when coordinating work in a GSD project, and that electronic chatting supports mutual adjustment. Further, co-location and modularization mitigates communication problems, enables agility in at least part of a GSD project, and renders the implementation of Scrum of Scrums possible.

    Full Text Available This paper presents the basis of the Agile Governance in Information and Communication Technology (ICT, which is based on Agile Software Engineering Methodologies principles and values. Its development was done through a systematic review process, supported by Bibliometrics and Scientometrics methods and techniques, where the Critical Success Factors (CSF of ICT Governance projects and the principles of the Agile Manifesto were analyzed. Next, through an inductive approach, focused on the convergence between the concepts involved, it was analyzed how agile principles could help to minimize the gap between ICT and business. Evidences of their occurrence were taken through a Conceptual Survey Research. As a result, the foundations and concepts of Agile Governance in ICT were defined and, finally, the development of a reference model was proposed as a future work.

    Korkala, Mikko; Pikkarainen, Minna; Conboy, Kieran

    Distributed development is a radically increasing phenomenon in modern software development environments. At the same time, traditional and agile methodologies and combinations of those are being used in the industry. Agile approaches place a large emphasis on customer communication. However, existing knowledge on customer communication in distributed agile development seems to be lacking. In order to shed light on this topic and provide practical guidelines for companies in distributed agile environments, a qualitative case study was conducted in a large globally distributed software company. The key finding was that it might be difficult for an agile organization to get relevant information from a traditional type of customer organization, even though the customer communication was indicated to be active and utilized via multiple different communication media. Several challenges discussed in this paper referred to "information blackout" indicating the importance of an environment fostering meaningful communication. In order to evaluate if this environment can be created a set of guidelines is proposed.

    Full Text Available Cool Down is very important for the recuperation of a football player. The objective of this research is to prove the effect of recuperation with static stretching in agility and isokinetic force at the young football players. This research has taken place between August and November 2015 with a sample of 24 football players of age 15.6±0.4 years, divided in the control group and the experimental group. At first measurements have been initialed body weight 61.1±0.4 kg and body height 175.7±6.4 cm, and agility (20 m zig-zag with and without ball and isokinetic force (peak torque flexion and extension. Both groups of the football players have completed the regular training program. The experimental group (despite the control group during the stage of recuperation (cool down, except the running with slow pace did also carry out the experimental program which did take place through static stretching. Experimental program consisted of 17 exercises bodily static stretching which are applied in the final training session (cool-down. After the experimental phase is finished the participants did undergo the final measures. The conducted results with univariate analysis of variance (ANOVA in two tests (initial and final have shown unimportant statistical values between the control group and the experimental one in the isokinetic force and agility. From the collected results we can conclude the recuperation with static stretching during the cool down has an unimportant statistical impact in the agility and isokinetic force of the young football players.

    To evaluate the effects of progressive resistance and balance (PRB) exercises on physical and psychological functions of post-stroke individuals. In a randomized controlled trial with follow-up at 3, 6 and 15 months, 67 community-living individuals (76% male; 65-85 years) with a stroke 1-3 years previously were allocated to an intervention group (IG, n = 34; PRB exercises combined with motivational group discussions twice weekly for 3 months) or a control group (CG, n = 33). The primary outcomes were balance (Berg Balance Scale, 0-56 points) and mobility (Short Physical Performance Battery, 0-12 points) at 3 months. The secondary outcomes were 10 m comfortable walking speed, physical activity levels, health-related quality of life, depression and fall-related self-efficacy. At 3 months, the IG exhibited significant improvements in balance (MD 2.5 versus 0 points; effect size [ES], 0.72; p resistance and balance exercise program supported by motivational group discussions and one home-based exercise appears to be an effective means of improving the short-term balance and the walking speed in individuals with chronic stroke. People with poor balance and motor function discontinued the study more often and may require additional support. There is a need for powerful and cost-effective strategies that target changes in behavior to obtain long-term changes in physical function after exercising.

    Agility is an important characteristic of team sports athletes. There is a growing interest in the factors that influence agility performance as well as appropriate testing protocols and training strategies to assess and improve this quality. The objective of this systematic review was to (1) evaluate the reliability and validity of agility tests in team sports, (2) detail factors that may influence agility performance, and (3) identify the effects of different interventions on agility performance. The review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We conducted a search of PubMed, Google Scholar, Science Direct, and SPORTDiscus databases. We assessed the methodological quality of intervention studies using a customized checklist of assessment criteria. Intraclass correlation coefficient values were 0.80-0.91, 0.10-0.81, and 0.81-0.99 for test time using light, video, and human stimuli. A low-level reliability was reported for youth athletes using the video stimulus (0.10-0.30). Higher-level participants were shown to be, on average, 7.5% faster than their lower level counterparts. Reaction time and accuracy, foot placement, and in-line lunge movement have been shown to be related to agility performance. The contribution of strength remains unclear. Efficacy of interventions on agility performance ranged from 1% (vibration training) to 7.5% (small-sided games training). Agility tests generally offer good reliability, although this may be compromised in younger participants responding to various scenarios. A human and/or video stimulus seems the most appropriate method to discriminate between standard of playing ability. Decision-making and perceptual factors are often propositioned as discriminant factors; however, the underlying mechanisms are relatively unknown. Research has focused predominantly on the physical element of agility. Small-sided games and video training may offer effective

    First, to evaluate the clinical effectiveness of a virtual reality (VR)-based telerehabilitation program in the balance recovery of individuals with hemiparesis after stroke in comparison with an in-clinic program; second, to compare the subjective experiences; and third, to contrast the costs of both programs. Single-blind, randomized, controlled trial. Neurorehabilitation unit. Chronic outpatients with stroke (N=30) with residual hemiparesis. Twenty 45-minute training sessions with the telerehabilitation system, conducted 3 times a week, in the clinic or in the home. First, Berg Balance Scale for balance assessment. The Performance-Oriented Mobility Assessment balance and gait subscales, and the Brunel Balance Assessment were secondary outcome measures. Clinical assessments were conducted at baseline, 8 weeks (posttreatment), and 12 weeks (follow-up). Second, the System Usability Scale and the Intrinsic Motivation Inventory for subjective experiences. Third, cost (in dollars). Significant improvement in both groups (in-clinic group [control] and a home-based telerehabilitation group) from the initial to the final assessment in the Berg Balance Scale (ηp(2)=.68; P=.001), in the balance (ηp(2)=.24; P=.006) and gait (ηp(2)=.57, P=.001) subscales of the Tinetti Performance-Oriented Mobility Assessment, and in the Brunel Balance Assessment (control: χ(2)=15.0; P=.002; experimental: χ(2)=21.9; P=.001). No significant differences were found between the groups in any balance scale or in the feedback questionnaires. With regard to subjective experiences, both groups considered the VR system similarly usable and motivating. The in-clinic intervention resulted in more expenses than did the telerehabilitation intervention ($654.72 per person). First, VR-based telerehabilitation interventions can promote the reacquisition of locomotor skills associated with balance in the same way as do in-clinic interventions, both complemented with a conventional therapy program

    The Open Geospatial Consortium (OGC), is the world leader industry consortium advancing geospatial technologies to help solve global challenges. The OGC brings the geospatial community together to advance standards, best practices and tools to improve sharing of geospatial data. The OGC Compliance program provides a free online testing facility [1], a process for certification [2] of compliant products, and coordination of a vibrant community of developers. The OGC testing facility is based on TEAM Engine, an open source software that is used by OGC and other geospatial communities to test web services, schemas, data and clients. The tests, which are also open source, are encoded in an XSLT like language called Compliance Testing language (CTL) and TestNG, a Java testing framework. TEAM Engine and related projects, as well as, each test have their own GitHub repository. The OGC Compliance program currently has more than 50 repositories. Releases of new revisions of tests and TEAM Engine are done every month, following a time boxed model. GitHub issue trackers are also use due to the easiness and close integration to the source code. However, GitHub issue trackers lack of the ability to order issues following an Agile methodology. Modern project management systems use a Kanban [3] approach to manage issues in a more efficient and focused way. About 10 organizations support the compliance program. A developer of an organization can take the lead of one or more projects and can participate on issues in other projects. However, coordinating the work to be done by one developer can be challenging due to the developer's participation in different projects and the difficulty of using a Kanban [3] approach directly from GitHub. This talk will provide a practical insight to manage projects using the Agile and Kanban methodologies when multiple developers participate in multiple GitHub projects. The ideas discussed in this talk will help organizations create more efficiently

    Sekulic, D, Pehar, M, Krolo, A, Spasic, M, Uljevic, O, Calleja-González, J, and Sattler, T. Evaluation of basketball-specific agility: applicability of preplanned and nonplanned agility performances for differentiating playing positions and playing levels. J Strength Cond Res 31(8): 2278-2288, 2017-The importance of agility in basketball is well known, but there is an evident lack of studies examining basketball-specific agility performances in high-level players. The aim of this study was to determine the reliability and discriminative validity of 1 standard agility test (test of preplanned agility [change-of-direction speed] over T course, T-TEST), and 4 newly developed basketball-specific agility tests, in defining playing positions and performance levels in basketball. The study comprised 110 high-level male basketball players (height: 194.92 ± 8.09 cm; body mass: 89.33 ± 10.91 kg; age: 21.58 ± 3.92 years). The variables included playing position (Guard, Forward, Center), performance level (first division vs. second division), anthropometrics (body height, body mass, and percentage of body fat), T-TEST, nonplanned basketball agility test performed on dominant (BBAGILdom) and nondominant sides (BBAGILnond), and a preplanned (change-of-direction speed) basketball agility test performed on dominant (BBCODSdom) and nondominant sides (BBCODSnond). The reliability of agility tests was high (intraclass correlation coefficient of 0.81-0.95). Forwards were most successful in the T-TEST (F test: 13.57; p = 0.01). Guards outperformed Centers in BBCODSdom, BBCODSndom, BBAGILdom, and BBAGILnond (F test: 5.06, p = 0.01; 6.57, 0.01; 6.26, 0.01; 3.37, 0.04, respectively). First division Guards achieved better results than second division Guards in BBCODSdom (t: 2.55; p = 0.02; moderate effect size differences), BBAGILdom, and BBAGILnond (t: 3.04 and 3.06, respectively; both p = 0.01 and moderate effect size differences). First division Centers outperformed second division

    Exercise programs aimed at improving balance are effective in fall prevention for older adults. Guidelines indicate that unstable elements should be integrated in balance training with this population. Balance training on an unstable surface facilitates proprioception mediated by skin receptors in the soles of the feet and by mechanoreceptors in the joints and muscles. This randomized controlled trial examined whether balance training performed using a foam rubber pad was more beneficial than balance training performed on a stable flat surface in older adults. Older adults using Japanese community day centers once or twice per week were enrolled in this trial. In total, 93 participants were randomized to 1 of 3 groups: foam rubber exercise group (n = 32), stable surface exercise group (n = 31), and control group (n = 30). Participants in the foam rubber and stable surface exercise groups attended a 60-minute exercise class once a week for 4 months and followed a home-based exercise routine. Outcome measures were the following performance tests: the one-leg standing test (OLST), the chair standing test, the timed up-and-go test (TUGT), and the tandem-stance test (TST). These assessments were conducted before the intervention, and at 1, 2, 3, and 4 months after starting the intervention. There were group × time interactions (P pad is effective for improving balance ability, and that this improvement occurs 2 months earlier compared with balance training performed on a stable surface. These findings suggest that balance training performed using a foam rubber pad is beneficial to clients and service providers because the programs improve physical functioning with a reduced number of exercise sessions.

    The Prevention of Falls Network Europe (ProFaNE) aims to bring together European researchers and clinicians to focus on the development of effective falls prevention programs for older people. One of the objectives is to identify suitable balance assessment tools. Assessment procedures that combine a balance task with a cognitive task may be relevant since part of all falls occurs during dual-task performance of walking or other balance activities. To evaluate whether dual-task balance assessments are more sensitive than single balance tasks in predicting falls and detecting changes in balance performance after fall interventions. A systematic literature search was performed in the databases PubMed, EMBASE, CINAHL, AMED, PsycINFO and Cochrane. Articles were selected according to the following inclusion criteria: (1) population: older adults (mean age > or =65 years), (2) assessment tool: dual task combining gait or other balance task with a cognitive task, (3) design: prospective or retrospective data collection of falls, or intervention study. Analysis of papers focused on measures of predictive ability or sensitivity-to-change for both tasks during dual-task performance as well as for the single balance and cognitive task. Out of 114 dual-task studies in older people, 19 articles matched the inclusion criteria. Fourteen studies had sample sizes of 60 subjects or less; the studied populations, task combinations as well as other methodological aspects varied. None of the articles reported the same statistical measures for both tasks during dual-task performance as well as single balance and cognitive task. In two studies with prospective data collection of falls, higher odds ratios were found for the dual compared to the single balance task. Upon the available literature, conclusions for an added value of dual balance tasks for fall prediction or assessing fall intervention effects cannot be made due to incomplete comparisons of single and dual balance tasks

    Full Text Available Motor competence (MC may be related to youth physical activity (PA level. In the last few years, MC has been studied as a possible determinant of children PA level, but has not been widely studied in adolescents. To analyze the relationship between MC and PA level 533 adolescents (271 men and 261 women from the southeast of Spain were assessed. To register weekly PA was used the International Physical Activity Questionnaire (IPAQ and for the MC, four coordination tests including throw and catch test, eye-hand and eye-foot coordination tests and agility circuit. Data were analyzed using ANOVA and binary logistic regression. The overall MC is consistently related with PA level. Eye-hand coordination test and the agility test define more accurately the tendency to high PA level. Programs to promote PA and focused on MC should be emphasized from early ages to adolescence.

    This study investigates the strategic antecedents of operational agility in humanitarian logistics. It began by identifying the particular actions to be taken at the strategic level of a humanitarian organisation to support field-level agility. Next, quantitative data (n=59) were collected on four strategic-level capabilities (being purposeful, action-focused, collaborative, and learning-oriented) and on operational agility (field responsiveness and flexibility). Using a quantitative analysis, the study tested the relationship between organisational capacity building and operational agility and found that the four strategic-level capabilities are fundamental building blocks of agility. Collectively they account for 52 per cent of the ability of humanitarian logisticians to deal with ongoing changes and disruptions in the field. This study emphasises the need for researchers and practitioners to embrace a broader perspective of agility in humanitarian logistics. In addition, it highlights the inherently strategic nature of agility, the development of which involves focusing simultaneously on multiple drivers. © 2017 The Author(s).

    2016-01-01

    Full Text Available Agile development methods are widely used among business enterprises. Since the introduction of the Agile Manifesto in 2001, several agile methods have been implemented, first in single-team set-ups and later in larger multi-team set-ups for complex Information Technology (IT system development. However, the adoption of agile methods has been slow in the public sector. This is also reflected in the academic literature, as there are only a few studies discussing agile adoption in public organizations. This paper contributes to research on the use of agile practices specifically in the context of public organizations, and sheds light on the challenges a public organization may face while adopting these practices. The aim of this paper is to identify and categorize the challenges that may hinder efficient adoption and use of agile methods in public IT projects that include private software vendors. This research is based on a case study of a large governmental office. As a result, this paper presents several categories of identified challenges, the root causes of these challenges, and a discussion of the characteristics of these challenges for the public sector.

    2014-03-01

    Full Text Available Background: Alpine skiing is a sport with a very complex structure and a high variability of movements. The stage of preliminary sport preparation in alpine skiing is important in a relation to the need of creating physical demands which enable an optimal and continuous growth of the performance. Inline skating is a very good substitution with a similar loading of lower limbs and muscle involvement as in skiing because inline skates offer a sense of sliding; stance and edge change and the technique for making curves are very similar. Objective: The main purpose of this paper was to assess the influence of a 9 week specialized training program on the changes in the level of balance abilities development of 8-10 year old children in alpine skiing. This specialized training program consisted of exercises on inline skates and from balance exercises on non-specific equipment. Methods: This research was organized by using a single-factor parallel experiment with two groups. Specialized motion program was 9 weeks long and it was used in the experimental group during the preparatory period in the stage of preliminary sport preparation. The experimental group completed a total of 90 minutes of specialized training per week, of which 60 minutes were special exercises on inline skates and 30 minutes were exercises for development of balance skills on non-specific tools. The control group underwent generally focused training. To determinate the level of balance we used tests of both static and dynamic balance. Results: Based on the tests results we found statistically significant improvement of the performance in all of the tests for balance abilities in the experimental group due to the specialized training program. The control group showed no significant differences during generally focused training process on the development of physical abilities. Conclusions: A 9 week training program consisting of 3 training sessions per week was long enough to

    Full Text Available Three-dimensional kinematic analysis examined agility running technique during pre-planned and reactive performance conditions specific to attacking ball carries in rugby union. The variation to running technique of 8 highly trained rugby union players was compared between agility conditions (pre-planned and reactive and also agility performance speeds (fast, moderate and slow. Kinematic measures were used to determine the velocity of the centre of mass (COM in the anteroposterior (running speed and mediolateral (lateral movement speed planes. The position of foot-strike and toe-off was also examined for the step prior to the agility side- step (pre-change of direction phase and then the side-step (change of direction phase. This study demonstrated that less lateral movement speed towards the intended direction change occurred during reactive compared to pre-planned conditions at pre-change of direction (0.08 ± 0.28 m·s-1 and 0.42 ± 0.25 m·s-1, respectively and change of direction foot-strikes (0.25 ± 0.42 m·s-1 and 0.69 ± 0.43 m·s-1, respectively. Less lateral movement speed during reactive conditions was associated with greater lateral foot displacement (44.52 ± 6.10% leg length at the change of direction step compared to pre-planned conditions (41.35 ± 5.85%. Importantly, the anticipation abilities during reactive conditions provided a means to differentiate between speeds of agility performance, with faster performances displaying greater lateral movement speed at the change of direction foot- strike (0.52 ± 0.34 m·s-1 compared to moderate (0.20 ± 0.37 m·s-1 and slow (-0.08 ± 0.31 m·s-1. The changes to running technique during reactive conditions highlight the need to incorporate decision-making in rugby union agility programs

    The relationship between balance ability and sport injury risk has been established in many cases, but the relationship between balance ability and athletic performance is less clear. This review compares the balance ability of athletes from different sports, determines if there is a difference in balance ability of athletes at different levels of competition within the same sport, determines the relationship of balance ability with performance measures and examines the influence of balance training on sport performance or motor skills. Based on the available data from cross-sectional studies, gymnasts tended to have the best balance ability, followed by soccer players, swimmers, active control subjects and then basketball players. Surprisingly, no studies were found that compared the balance ability of rifle shooters with other athletes. There were some sports, such as rifle shooting, soccer and golf, where elite athletes were found to have superior balance ability compared with their less proficient counterparts, but this was not found to be the case for alpine skiing, surfing and judo. Balance ability was shown to be significantly related to rifle shooting accuracy, archery shooting accuracy, ice hockey maximum skating speed and simulated luge start speed, but not for baseball pitching accuracy or snowboarding ranking points. Prospective studies have shown that the addition of a balance training component to the activities of recreationally active subjects or physical education students has resulted in improvements in vertical jump, agility, shuttle run and downhill slalom skiing. A proposed mechanism for the enhancement in motor skills from balance training is an increase in the rate of force development. There are limited data on the influence of balance training on motor skills of elite athletes. When the effectiveness of balance training was compared with resistance training, it was found that resistance training produced superior performance results for

    Aims: Since the CGRO operation in 1991-2000, one of the primary unresolved questions about the blazar γ-ray emission has been its possible correlation with the low-energy (in particular optical) emission. To help answer this problem, the Whole Earth Blazar Telescope (WEBT) consortium has organized the GLAST-AGILE Support Program (GASP) to provide the optical-to-radio monitoring data to be compared with the γ-ray detections by the AGILE and GLAST satellites. This new WEBT project started in early September 2007, just before a strong γ-ray detection of 0716+714 by AGILE. Methods: We present the GASP-WEBT optical and radio light curves of this blazar obtained in July-November 2007, about various AGILE pointings at the source. We construct NIR-to-UV spectral energy distributions (SEDs), by assembling GASP-WEBT data together with UV data from the Swift ToO observations of late October. Results: We observe a contemporaneous optical-radio outburst, which is a rare and interesting phenomenon in blazars. The shape of the SEDs during the outburst appears peculiarly wavy because of an optical excess and a UV drop-and-rise. The optical light curve is well sampled during the AGILE pointings, showing prominent and sharp flares. A future cross-correlation analysis of the optical and AGILE data will shed light on the expected relationship between these flares and the γ-ray events. The radio-to-optical data presented in this paper are stored in the WEBT archive; for questions regarding their availability, please contact the WEBT President Massimo Villata.

    "Cicada: a Heavy but Agile Flyer" is a fluid dynamic video submitted to Gallery of Fluid Motion in APS-DFD 2011. Comparing to other insects, cicadas can generate much higher lift to overcome their large body weight. The hidden mechanism may help in designing a Micro Air Vehicle (MAV) to carry large payloads. However, it is lack of literatures in discussing how cicadas use their wings to accomplish various fights. In this work, a high-speed photogrammetry system and 3D surface reconstruction technology are used to reveal cicada wing kinematics and deformation during a freely forward flight. The aerodynamic performance is studied using in-house immerse boundary method based Computational Fluid Dynamics(CFD) solver.

    The Resource Prospector (RP) is an in-situ resource utilization (ISRU) technology demonstration mission, designed to search for volatiles at the Lunar South Pole. This is NASA's first near real time tele-operated rover on the Moon. The primary objective is to search for volatiles at one of the Lunar Poles. The combination of short mission duration, a solar powered rover, and the requirement to explore shadowed regions makes for an operationally challenging mission. To maximize efficiency and flexibility in Mission System design and thus to improve the performance and reliability of the resulting Mission System, we are tailoring Agile principles that we have used effectively in ground data system software development and applying those principles to the design of elements of the mission operations system.

  4. Using agility to combat cyber attacks.

    2017-06-01

    Some incident response practitioners feel that they have been locked in a battle with cyber criminals since the popular adoption of the internet. Initially, organisations made great inroads in preventing and containing cyber attacks. In the last few years, however, cyber criminals have become adept at eluding defence security technologies and rapidly modifying their exploit strategies for financial or political gains. Similar to changes in military combat tactics, cyber criminals utilise distributed attack cells, real-time communications, and rapidly mutating exploits to minimise the potential for detection. Cyber criminals have changed their attack paradigm. This paper describes a new incident response paradigm aimed at combating the new model of cyber attacks with an emphasis on agility to increase the organisation's ability to respond rapidly to these new challenges.

    To study the validity of a video-based reactive agility test in Australian footballers. 15 higher performance, 15 lower performance, and 12 nonfootballers completed a light-based reactive agility test (LRAT), a video-based reactive agility test (VRAT), and a planned test (PLAN). With skill groups pooled, agility time in PLAN (1346 ± 66 ms) was significantly faster (P = .001) than both reactive tests (VRAT = 1550 ± 102 ms; LRAT = 1572 ± 97 ms). In addition, decision time was significantly faster (P = .001; d = 0.8) in LRAT (278 ± 36 ms) than VRAT (311 ± 47 ms). The correlation in agility time between the two reactive tests (r = .75) was higher than between the planned and reactive tests (r = .41-.68). Higher performance players had faster agility and movement times on VRAT (agility, 130 ± 24 ms, d = 1.27, P = .004; movement, 69 ± 73 ms, d = 0.88, P = .1) and LRAT (agility, 95 ± 86 ms, d = 0.99, P = .08; movement, 79 ± 74 ms; d = 0.9; P = .08) than the nonfootballers. In addition, higher (55 ± 39 ms, d = 0.87, P = .05) and lower (40 ± 57 ms, d = 0.74, P = .18) performance groups exhibited somewhat faster agility time than nonfootballers on PLAN. Furthermore, higher performance players were somewhat faster than lower performance for agility time on the VRAT (63 ± 85 ms, d = 0.82, P = .16) and decision time on the LRAT (20 ± 39 ms, d = 0.66, P = .21), but there was little difference in PLAN agility time between these groups (15 ± 150 ms, d = 0.24, P = .8). Differences in decision-making speed indicate that the sport-specific nature of the VRAT is not duplicated by a light-based stimulus. In addition, the VRAT is somewhat better able to discriminate different groups of Australian footballers than the LRAT. Collectively, this indicates that a video-based test is a more valid assessment tool for examining agility in Australian footballers.

    Research in the late 80's on technological companies that develop products of high value innovation, with sufficient speed and flexibility to adapt quickly to changing market conditions, gave rise to the new set of methodologies known as Agile Management Approach. In the current changing economic scenario, we considered very interesting to study the similarities of these Agile Methodologies with other practices whose effectiveness has been amply demonstrated in both the West and Japan. Strategies such as Kaizen, Lean, World Class Manufacturing, Concurrent Engineering, etc, would be analyzed to check the values they have in common with the Agile Approach.

    Full Text Available Abstract Background In bioinformatics projects, scientific workflow systems are widely used to manage computational procedures. Full-featured workflow systems have been proposed to fulfil the demand for workflow management. However, such systems tend to be over-weighted for actual bioinformatics practices. We realize that quick deployment of cutting-edge software implementing advanced algorithms and data formats, and continuous adaptation to changes in computational resources and the environment are often prioritized in scientific workflow management. These features have a greater affinity with the agile software development method through iterative development phases after trial and error. Here, we show the application of a scientific workflow system Pwrake to bioinformatics workflows. Pwrake is a parallel workflow extension of Ruby's standard build tool Rake, the flexibility of which has been demonstrated in the astronomy domain. Therefore, we hypothesize that Pwrake also has advantages in actual bioinformatics workflows. Findings We implemented the Pwrake workflows to process next generation sequencing data using the Genomic Analysis Toolkit (GATK and Dindel. GATK and Dindel workflows are typical examples of sequential and parallel workflows, respectively. We found that in practice, actual scientific workflow development iterates over two phases, the workflow definition phase and the parameter adjustment phase. We introduced separate workflow definitions to help focus on each of the two developmental phases, as well as helper methods to simplify the descriptions. This approach increased iterative development efficiency. Moreover, we implemented combined workflows to demonstrate modularity of the GATK and Dindel workflows. Conclusions Pwrake enables agile management of scientific workflows in the bioinformatics domain. The internal domain specific language design built on Ruby gives the flexibility of rakefiles for writing scientific workflows

    Safety related systems are traditionally developed using traditional models like the V-model. Agile development models are now increasingly used, and the experiences with these models makes it tempting to also use Agile models when developing safety related systems. To do this, Agile development models need include a safety process that also are as agile as possible. However, introducing safety activities into an agile environment reintroduces limitations from traditional de-velopment. The...

While much research claims to study agile methods, the meaning of agility itself in software development is yet to be fully understood. Agility is viewed by some as the antithesis of plan, structure discipline and bureaucracy. This study aims to develop a better understanding of agility, using the key concepts of Complex Adaptive Systems as a...

    Background Dance performance requires not only lower extremity muscle strength and endurance, but also sufficient core stabilization during dynamic dance movements. While previous studies have identified a link between core muscle performance and lower extremity injury risk, what has not been determined is if an extended core stabilization training program will improve specific measures of dance performance. Hypothesis/Purpose This study examined the impact of a nine-week core stabilization program on indices of dance performance, balance measures, and core muscle performance in competitive collegiate dancers. Study Design Within-subject repeated measures design. Methods A convenience sample of 24 female collegiate dance team members (age = 19.7 ± 1.1 years, height = 164.3 ± 5.3 cm, weight 60.3 ± 6.2 kg, BMI = 22.5 ± 3.0) participated. The intervention consisted of a supervised and non-supervised core (trunk musculature) exercise training program designed specifically for dance team participants performed three days/week for nine weeks in addition to routine dance practice. Prior to the program implementation and following initial testing, transversus abdominis (TrA) activation training was completed using the abdominal draw-in maneuver (ADIM) including ultrasound imaging (USI) verification and instructor feedback. Paired t tests were conducted regarding the nine-week core stabilization program on dance performance and balance measures (pirouettes, single leg balance in passe’ releve position, and star excursion balance test [SEBT]) and on tests of muscle performance. A repeated measures (RM) ANOVA examined four TrA instruction conditions of activation: resting baseline, self-selected activation, immediately following ADIM training and four days after completion of the core stabilization training program. Alpha was set at 0.05 for all analysis. Results Statistically significant improvements were seen on single leg balance in passe

    The DET/MPS programs model and simulate the Direct Energy Transfer and Multimission Spacecraft Modular Power System in order to aid both in design and in analysis of orbital energy balance. Typically, the DET power system has the solar array directly to the spacecraft bus, and the central building block of MPS is the Standard Power Regulator Unit. DET/MPS allows a minute-by-minute simulation of the power system's performance as it responds to various orbital parameters, focusing its output on solar array output and battery characteristics. While this package is limited in terms of orbital mechanics, it is sufficient to calculate eclipse and solar array data for circular or non-circular orbits. DET/MPS can be adjusted to run one or sequential orbits up to about one week, simulated time. These programs have been used on a variety of Goddard Space Flight Center spacecraft projects. DET/MPS is written in FORTRAN 77 with some VAX-type extensions. Any FORTRAN 77 compiler that includes VAX extensions should be able to compile and run the program with little or no modifications. The compiler must at least support free-form (or tab-delineated) source format and 'do do-while end-do' control structures. DET/MPS is available for three platforms: GSC-13374, for DEC VAX series computers running VMS, is available in DEC VAX Backup format on a 9-track 1600 BPI tape (standard distribution) or TK50 tape cartridge; GSC-13443, for UNIX-based computers, is available on a .25 inch streaming magnetic tape cartridge in UNIX tar format; and GSC-13444, for Macintosh computers running AU/X with either the NKR FORTRAN or AbSoft MacFORTRAN II compilers, is available on a 3.5 inch 800K Macintosh format diskette. Source code and test data are supplied. The UNIX version of DET requires 90K of main memory for execution. DET/MPS was developed in 1990.

    Court sports often require more frequent changes of direction (COD) than field sports. Most court sports require 180 degrees turns over a small distance, so COD in such sports might be best evaluated with an agility test involving short sprints and sharp turns. The purposes of this study were to (a) quantify vertical and horizontal force during a COD task, (b) identify possible predictors of court-sport-specific agility performance, and (c) examine performance difference between National Collegiate Athletic Association Division I, II, and III athletes. Twenty-nine collegiate female volleyball players completed a novel agility test, countermovement (CM) and drop jump tests, and an isometric leg extensor test. The number of athletes by division was as follows: I (n = 9), II (n = 11), and III (n = 9). The agility test consisted of 4 5-meter sprints with 3 180 degrees turns, including 1 on a multiaxial force platform so that the kinetic properties of the COD could be identified. One-way analysis of variance revealed that Division I athletes had significantly greater countermovement jump heights than Division III, and the effect size comparisons (Cohen's d) showed large-magnitude differences between Division I and both Divisions II and III for jump height. No other differences in performance variables were noted between divisions, although effect sizes reached moderate values for some comparisons. Regression analysis revealed that CM displacement was a significant predictor of agility performance, explaining approximately 34% of the variance. Vertical force was found to account for much of the total force exerted during the contact phase of the COD task, suggesting that performance in the vertical domain may limit the COD task used herein. This study indicates that individuals with greater CM performance also have quicker agility times and suggests that training predominantly in the vertical domain may also yield improvements in certain types of agility performance

    Full Text Available As businesses are encountering frequent harsh economic conditions, concepts such as outsourcing, agile and lean management, change management and cost reduction are constantly gaining more attention. This is because these concepts are all aimed at saving on budgets and facing unexpected changes. Latest technologies like cloud computing promise to turn IT, that has always been viewed as a cost centre, into a source of saving money and driving flexibility and agility to the business. The purpose of this paper is to first compile a set of attributes that govern the agility benefits added to information systems by cloud computing and then develop a survey-based instrument to measure these agility benefits. Our research analysis employs non-probability sampling based on a combination of convenience and judgment. This approach was used to obtain a representative sample of participants from potential companies belonging to various industries such as oil & gas, banking, private, government and semi-governmental organizations. This research will enable decision makers to measure agility enhancements and hence compare the agility of Information Systems before and after deploying cloud computing.

    Dizziness and unsteadiness are common symptoms following a whiplash injury. To compare the effect of 3 exercise programs on balance, dizziness, proprioception and pain in patients with chronic whiplash complaining of dizziness. A sub-analysis of a randomized study. One hundred and forty subjects were randomized to either a physiotherapist-guided neck-specific exercise (NSE), physiotherapist-guided neck-specific exercise, with a behavioural approach (NSEB) or prescription of general physical activity (PPA) group. Pre intervention, 3, 6 and 12 months post baseline they completed the University of California Los Angeles Dizziness Questionnaire (UCLA-DQ), Visual Analogue Scales (VAS) for, dizziness at rest and during activity and physical measures (static and dynamic clinical balance tests and head repositioning accuracy (HRA)). There were significant time by group differences with respect to dizziness during activity and UCLA-Q favouring the physiotherapy led neck specific exercise group with a behavioural approach. Within group analysis of changes over time also revealed significant changes in most variables apart from static balance. Between and within group comparisons suggest that physiotherapist led neck exercise groups including a behavioural approach had advantages in improving measures of dizziness compared with the general physical activity group, although many still complained of dizziness and balance impairment. Future studies should consider exercises specifically designed to address balance, dizziness and cervical proprioception in those with persistent whiplash. Crown Copyright © 2015.

    Older people with dementia are at increased risk of physical decline and falls. Balance and mood are significant predictors of falls in this population. The aim of this study was to determine the effect of a tailored home-based exercise program in community-dwelling older people with dementia. Forty-two participants with mild to moderate dementia were recruited from routine health services. All participants were offered a six-month home-based, carer-enhanced, progressive, and individually tailored exercise program. Physical activity, quality of life, physical, and psychological assessments were administered at the beginning and end of the trial. Of 33 participants (78.6%) who completed the six-month reassessment ten (30%) reported falls and six (18%) multiple falls during the follow-up period. At reassessment, participants had better balance (sway on floor and foam), reduced concern about falls, increased planned physical activity, but worse knee extension strength and no change in depression scores. The average adherence to the prescribed exercise sessions was 45% and 22 participants (52%) were still exercising at trial completion. Those who adhered to ≥70% of prescribed sessions had significantly better balance at reassessment compared with those who adhered to exercise intervention presents preliminary evidence that this intervention can improve balance, concern about falls, and planned physical activity in community-dwelling older people with dementia. Future research should determine whether exercise interventions are effective in reducing falls and elucidate strategies for enhancing uptake and adherence in this population.

    Science.gov (United States)

    2014-01-01

    Background Caffeine (CAF) has been shown to improve performance during early phase of repeated sprint exercise; however some studies show that CAF also increases the magnitude of physical stress represented by augmented blood lactate, glucose, and cortisol concentrations during latter phase of repeated sprint exercise. No studies have investigated the efficacy of combined carbohydrate (CHO) and CAF consumption during repeated sprint exercise (RSE) in female athletes. Thus, the purpose of this study was to investigate the effects of CAF with CHO supplementation on RSE and agility. Methods Eleven female athletes completed four experimental trials performed 7 d apart in a double-blind, randomized, and counter-balanced crossover design. Treatments included CAF + PLA (placebo), CAF + CHO, PLA + CHO, and PLA + PLA. Participants ingested capsules containing 6 mg · kg−1 of CAF or PLA 60-min prior to RSE, and 0.8 g · kg−1 of CHO solution or PLA immediately before the RSE, which consisted of ten sets of 5 × 4-s sprints on the cycle ergometer with 20-s active recovery. The agility T-test (AT-test) was performed before and after the RSE. Blood samples were acquired to assess glucose, lactate, testosterone, and cortisol. Results During Set 6 of RSE, peak power and mean power were significantly higher in PLA + CHO than those in CAF + PLA and PLA + PLA, respectively (p  .05). Blood lactate and glucose concentrations were significantly higher under CAF + CHO, CAF + PLA, and PLA + CHO versus PLA + PLA (p  .05). Conclusions Findings indicate that CAF + PLA or CAF + CHO ingestion did not improve repeated sprint performance with short rest intervals or agility. However, CHO ingested immediately prior to exercise provided a small but significant benefit on RSE performance in female athletes. PMID:24855458

    Full Text Available INTRODUCTION: in soccer, agility is a relevant parameter that is defined as the ability to change the direction of the body rapidly and is a result of a combination of strength, speed, balance and coordination. OBJECTIVE: to demonstrated the reliability and validity of the modified Barrow test in soccer players aged 10 to 14 years, analyze its relationship with age, maturation, experience and body size and test the effectiveness of the protocol for distinguishing performance changes during a 10-month competitive season. METHODS: fifty-one adolescent Basque soccer players were enrolled. Age, maturation, experience, body size, vertical jump and 15-m sprint were measured. The reliability of the test was analyzed using replicate tests in a subgroup n = 34. Another subgroup of 33 players n =18, under-11, 10.4 ± 0.3 years; n = 15 under-13, 12.0 ± 0.8 years was evaluated at the beginning and the end of the season. RESULTS: the reliability of the test was good change in mean = -0.5%, 95% CI -1.2 to 0.2, SD=0.14; coefficient of variation = 0.9%, 95% CI - 0.7 to 1.5, SD=0.25. Chronological age and adiposity were significant predictors of agility performance P<0.01. An improvement in performance was observed over a 10-month soccer season, with a significant group effect P<0.01. CONCLUSION: the agility test demonstrated logic and validity, and proved to be a reliable and objective instrument for assessing adolescent soccer players.

    Age-related degenerations in brain structure are associated with balance disturbances and cognitive impairment. However, neuroplasticity is known to be preserved throughout lifespan and physical training studies with seniors could reveal volume increases in the hippocampus (HC), a region crucial for memory consolidation, learning and navigation in space, which were related to improvements in aerobic fitness. Moreover, a positive correlation between left HC volume and balance performance was observed. Dancing seems a promising intervention for both improving balance and brain structure in the elderly. It combines aerobic fitness, sensorimotor skills and cognitive demands while at the same time the risk of injuries is low. Hence, the present investigation compared the effects of an 18-month dancing intervention and traditional health fitness training on volumes of hippocampal subfields and balance abilities. Before and after intervention, balance was evaluated using the Sensory Organization Test and HC volumes were derived from magnetic resonance images (3T, MP-RAGE). Fourteen members of the dance (67.21 ± 3.78 years, seven females), and 12 members of the fitness group (68.67 ± 2.57 years, five females) completed the whole study. Both groups revealed hippocampal volume increases mainly in the left HC (CA1, CA2, subiculum). The dancers showed additional increases in the left dentate gyrus and the right subiculum. Moreover, only the dancers achieved a significant increase in the balance composite score. Hence, dancing constitutes a promising candidate in counteracting the age-related decline in physical and mental abilities.

    Sailing might produce a positive effect on a patient's general health and become an integrated part of rehabilitation. Our hypothesis was that a specific technological rehabilitation program might be used to prepare a group of disabled subjects for sailing. Seventeen patients (age range: 9-20) with impairments in motor coordination and balance and 15 healthy subjects participated in the study. The study was divided into the virtual-technological sailing phase, theory-practice phase, and sports phase. Proprioceptive platforms were used to evaluate balance, and the Child Health Questionnaire-PF50 was used to evaluate quality of life. Trunk displacement and the center of pressure velocity improved significantly after the virtual-technological sailing program. As regards quality of life, the physical and psychosocial score significantly improved at the end of the program. A technological rehabilitation training improved balance in disabled subjects and may be used to prepare them for a real sailing course. Sailing improves the quality of life of disabled subjects and could be used in the rehabilitation. © The Author(s) 2016.

    The aim of this study was to establish the effects of core strengthening exercise program on trunk instability in response to vertical jump performances and static balance variables in volleyball players. As a core stabilization program aids in developing a stable spine over the pelvis and improves trunk stability this concept should be incorporated in sports tasks involving jump and reach in those with an unstable spine. Forty state level volleyball players with trunk instability were randomly divided into two groups, control ([C] m=10; f=10) and experimental ([E] m=10; f=10). Modified double straight leg lowering test was used to check the degree of trunk instability. Counter movement jump, squat jump, spike jump and block jumps were used to measure jumping abilities and a wobble board test was used to test balance. Pre- and postreadings were noted before and after the nine-week training protocol and statistical data analysis was done using SPSS 16. After nine weeks of core stabilization training, trunk stability (Pjump (Pjump (d=0.25) and block jump (d=0.52) in (E) group. Other jumps and static balance were improved but non-significant when compared between groups. Nine-week strategic core strengthening exercise program increases trunk stability and in turn improves block difference (vertical jump parameter).

    The Multi Mission Bus Demonstrator (MBD) is a successful demonstration of agile program management and system engineering in a high risk technology application where utilizing and implementing new, untraditional development strategies were necessary. MBD produced two fully functioning spacecraft for a military/DOD application in a record breaking time frame and at dramatically reduced costs. This paper discloses the adaptation and application of concepts developed in agile software engineering to hardware product and system development for critical military applications. This challenging spacecraft did not use existing key technology (heritage hardware) and created a large paradigm shift from traditional spacecraft development. The insertion of new technologies and methods in space hardware has long been a problem due to long build times, the desire to use heritage hardware, and lack of effective process. The role of momentum in the innovative process can be exploited to tackle ongoing technology disruptions and allowing risk interactions to be mitigated in a disciplined manner. Examples of how these concepts were used during the MBD program will be delineated. Maintaining project momentum was essential to assess the constant non recurring technological challenges which needed to be retired rapidly from the engineering risk liens. Development never slowed due to tactical assessment of the hardware with the adoption of the SCRUM technique. We adapted this concept as a representation of mitigation of technical risk while allowing for design freeze later in the program's development cycle. By using Agile Systems Engineering and Management techniques which enabled decisive action, the product development momentum effectively was used to produce two novel space vehicles in a fraction of time with dramatically reduced cost.

    With increasing age neuromuscular deficits (e.g., sarcopenia) may result in impaired physical performance and an increased risk for falls. Prominent intrinsic fall-risk factors are age-related decreases in balance and strength / power performance as well as cognitive decline. Additional studies are needed to develop specifically tailored exercise programs for older adults that can easily be implemented into clinical practice. Thus, the objective of the present trial is to assess the effects of a fall prevention program that was developed by an interdisciplinary expert panel on measures of balance, strength / power, body composition, cognition, psychosocial well-being, and falls self-efficacy in healthy older adults. Additionally, the time-related effects of detraining are tested. Healthy old people (n = 54) between the age of 65 to 80 years will participate in this trial. The testing protocol comprises tests for the assessment of static / dynamic steady-state balance (i.e., Sharpened Romberg Test, instrumented gait analysis), proactive balance (i.e., Functional Reach Test; Timed Up and Go Test), reactive balance (i.e., perturbation test during bipedal stance; Push and Release Test), strength (i.e., hand grip strength test; Chair Stand Test), and power (i.e., Stair Climb Power Test; countermovement jump). Further, body composition will be analysed using a bioelectrical impedance analysis system. In addition, questionnaires for the assessment of psychosocial (i.e., World Health Organisation Quality of Life Assessment-Bref), cognitive (i.e., Mini Mental State Examination), and fall risk determinants (i.e., Fall Efficacy Scale - International) will be included in the study protocol. Participants will be randomized into two intervention groups or the control / waiting group. After baseline measures, participants in the intervention groups will conduct a 12-week balance and strength / power exercise intervention 3 times per week, with each training session lasting 30 min

    [Purpose] The purpose of this study was to compare changes in balance ability of land exercise and underwater exercise on chronic stroke patients. [Subjects] A total of 60 patients received exercise for 40 minutes, three times a week, for 6 weeks. [Methods] Subjects from both groups performed general conventional treatment during the experimental period. In addition, all subjects engaged in extra treatment sessions. This extra treatment consisted of unstable surface exercise. The underwater exercise group used wonder boards in a pool (depth 1.1m, water temperature 33.5 °C, air temperature 27 °C) dedicated to underwater exercise, and the land exercise group used balance mats. [Result] The joint position sense, sway area, Berg Balance Scale showed significant improvements in both groups. However, the joint position sense test, sway area, and Berg Balance Scale showed there was more improvement in the underwater exercise group than in the land exercise group. [Conclusion] The results suggest that underwater exercise is more effective than land exercise at improving the joint position sense and balance of stroke patients.

    The geochemical models consists on the application of physical-chemical principles to the interpretation of hydrogeochemical systems. This methodology has been developed according to two approaches: a) the inverse one, mass-balance, that uses a well-known data of the chemical composition of the water and the rock with the objective of identifying in a quantitative way the geochemical reactions that give origin to this composition, and b) the direct one that in the basis of some well-known initial conditions of the water-rock system, it predicts the characteristics of the resulting solution of the performance of hypothetical chemical reactions. With the reference of interactive programs such as BALANCE and NETPATH, for modelling net geochemical mass-balance reactions between an initial and final water along a hydrologic flow path, which also computes the mixing proportion of two initial waters and net geochemical reactions that can account for the observed composition of a final water, an interactive program of inverse model has been developed (MODELAGUA) that not only allow starting from well-known data of the chemical composition of the water and the rock to identify in a quantitative way the geochemical reactions that give origin to this composition, but allow to do analysis of mixture of waters and net geochemical reactions that can account for the observed composition of a final water, making use of natural tracer whose geochemical behavior allows them to be used as conservative ions. In this work is presented MODELAGUA, as a new interactive program of inverse model mass-balance and an example in Aguascalientes, Mexico of its application.

    Balance training is often employed for the prevention of ankle injuries. However, until now, most of the studies have focused on the prevention of a recurrent injury. The objective of this study was to look into the effects of balance training on the onset of peroneal muscle activity in healthy subjects. 34 participants (mean age = 19.5 years ± 1.5; height = 1.70 m ± 0.12; weight = 62.06 kg ± 11.24), physically active, with no history of injuries took part in this study. The participants underwent a 4-week balance training program using an ankle disk. Onset of peroneal muscles activation was measured using surface electromyography and a trap-door. Parametric and non-parametric tests showed no significant differences between the control group and the experimental group (P > 0.05). The results indicate that the use of balance training, for a 4-week period with two training sessions per week, on physically active subjects with no history of injuries in the ankle joint, does not cause noteworthy changes on the onset of peroneal muscles activity.

    To investigate the effects of a high-intensity functional exercise program on independence in activities of daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types. Cluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study. Residential care facilities, Umeå, Sweden. Individuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N=186). Ninety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity. Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months. Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=-1.6-4.3; BI=0.6, 95% CI=-0.2-1.4) or 7 (FIM=0.8, 95% CI=-2.2-3.8; BI=0.6, 95% CI=-0.3-1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8-6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months. In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia. © 2016 The Authors.

  1. Distilling Design Patterns From Agile Curation Case Studies

    2016-12-01

    In previous work the authors have argued that there is a need to take a new look at the data management lifecycle. Our core argument is that the data management lifecycle needs to be in essence deconstructed and rebuilt. As part of this process we also argue that much can be gained from applying ideas, concepts, and principles from agile software development methods. To be sure we are not arguing for a rote application of these agile software approaches, however, given various trends related to data and technology, it is imperative to update our thinking about how to approach the data management lifecycle, recognize differing project scales, corresponding variations in structure, and alternative models for solving the problems of scientific data curation. In this paper we will describe what we term agile curation design patterns, borrowing the concept of design patterns from the software world and we will present some initial thoughts on agile curation design patterns as informed by a sample of data curation case studies solicited from participants in agile data curation meeting sessions conducted in 2015-16.

    To improve lower extremity function and balance in elderly persons, we developed a novel, three-dimensional interactive augmented reality system (3D ARS). In this feasibility study, we assessed clinical and kinematic improvements, user participation, and the side effects of our system. Eighteen participants (age, 56-76 years) capable of walking independently and standing on one leg were recruited. The participants received 3D ARS training during 10 sessions (30-minute duration each) for 4 weeks. Berg Balance Scale (BBS) and the Timed Up and Go (TUG) scores were obtained before and after the exercises. Outcome performance variables, including response time and success rate, and kinematic variables, such as hip and knee joint angle, were evaluated after each session. Participants exhibited significant clinical improvements in lower extremity balance and mobility following the intervention, as shown by improved BBS and TUG scores (pincreased across sessions (p<0.001). All participants completed the program without experiencing any adverse effects. Substantial clinical and kinematic improvements were observed after applying a novel 3D ARS training program, suggesting that this system can enhance lower extremity function and facilitate assessments of lower extremity kinematic capacity.

    2015-01-01

    This study compared sit to stand (STS) performance between older adults in a nine-week training program focusing on core stability exercises to enhance balance and postural control (EB) versus standard balance (SB) exercises. Repetitions in 30 s (STSreps) and kinematic performance (vertical and horizontal momentum, and margin of stability) were measured pre and postintervention in 23 older adults with at least one fall risk factor. Although both groups combined improved STSreps (P = .001) and vertical momentum (.008), a significant between-group difference was observed for completers only (MANCOVA of posttest group differences, with pretest scores as covariates; P = .04). EB demonstrated a greater but nonsignificant improvement in vertical momentum (P = .095). In conclusion, core stability training added to SB did not result in STS reps improvement. Compliance may modify these results and future larger sample studies should evaluate the impact of core stability training on STS biomechanics.

    Kussmaul, Clifton

    This chapter reflects on case study based an agile distributed project that ran for approximately three years (from spring 2003 to spring 2006). The project involved (a) a customer organization with key personnel distributed across the US, developing an application with rapidly changing requirements; (b) onshore consultants with expertise in project management, development processes, offshoring, and relevant technologies; and (c) an external offsite development team in a CMM-5 organization in southern India. This chapter is based on surveys and discussions with multiple participants. The several years since the project was completed allow greater perspective on both the strengths and weaknesses, since the participants can reflect on the entire life of the project, and compare it to subsequent experiences. Our findings emphasize the potential for agile project management in distributed software development, and the importance of people and interactions, taking many small steps to find and correct errors, and matching the structures of the project and product to support implementation of agility.

  11. Architected Agile Solutions for Software-Reliant Systems

    Boehm, Barry; Lane, Jo Ann; Koolmanojwong, Supannika; Turner, Richard

    Systems are becoming increasingly reliant on software due to needs for rapid fielding of “70% capabilities,” interoperability, net-centricity, and rapid adaptation to change. The latter need has led to increased interest in agile methods of software development, in which teams rely on shared tacit interpersonal knowledge rather than explicit documented knowledge. However, such systems often need to be scaled up to higher level of performance and assurance, requiring stronger architectural support. Several organizations have recently transformed themselves by developing successful combinations of agility and architecture that can scale to projects of up to 100 personnel. This chapter identifies a set of key principles for such architected agile solutions for software-reliant systems, provides guidance for how much architecting is enough, and illustrates the key principles with several case studies.

    Adopting agile isn’t as simple as ticking practices off a known list and moving onto the next one. It takes some effort to simply start applying a practice, and even more effort to attain a certain level of mastery. Distinguishing between apprentice-like behaviours and master-like behaviours is an important element of pushing the boundaries of a practice even more. This workshop uses the Dreyfus Model of Skill Acquisition to map behaviours we see in agile practices to the model and learn how to use this model to as a tool to help people progress to further levels of mastery within a particular practice.

    2015-08-01

    The aim of this study was to first determine differences in neuromuscular strategy between a faster and slower agility performance, and second compare differences in muscle activation strategy employed when performing two closely executed agility movements. Participants recruited from an elite female basketball team completed an ultrasound to determine quadriceps muscle-cross sectional area; reactive isometric mid-thigh pull to determine the rate of muscle activation, rate of force development, pre-motor time and motor time; and multidirectional agility tests completing two directional changes in response to a visual stimulus. Peak and average relative muscle activation of the rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinosus and gastrocnemius were measured 100ms prior to heel strike (pre-heel strike) and across stance phase for both directional changes. Faster agility performance was characterized by greater pre-heel strike muscle activity and greater anterior muscle activation during stance phase resulting in greater hip and knee extension increasing propulsive impulse. Differences between directional changes appear to result from processing speed, where a greater delay in refractory times during the second directional change resulted in greater anterior muscle activation, decelerating the body while movement direction was determined.

  15. Adapt! – Agile Project Management Supported by Axiomatic Design

    2017-01-01

    Full Text Available This paper presents a novel approach for the use of Axiomatic Design Theory in combination with agile project management methods like Scrum for an effective, structured and combined product design and development process. Agile project management methods give a guideline how to manage a project, but there is only minor assistance regarding the actual product development process itself. Axiomatic Design can be used to support these methods in this point. In concrete terms, the results of the decomposition process of this theory can be used to formulate and structure the work packages for the agile project managing process. The Independence Axiom of Axiomatic Design Theory has a substantial contribution by ensuring the independence of the work packages which can be assigned to different project team members and can be processed independently by them. The combination of the different methods not only helps to ensure a good design solution but also helps to work more agile within a project team. The here proposed approach is one part of a holistic product design and development process for changeable production units – called Adapt! – and is described within a use case in the automotive sector.

  16. Cloud Computing as an Enabler of Agile Global Software Development

    2016-05-01

    Full Text Available Agile global software development (AGSD is an increasingly prevalent software development strategy, as organizations hope to realize the benefits of accessing a larger resource pool of skilled labor, at a potentially reduced cost, while at the same time delivering value incrementally and iteratively. However, the distributed nature of AGSD creates geographic, temporal, socio-cultural distances that challenge collaboration between project stakeholders. The Cloud Computing (CC service models of Infrastructure as a Service (IaaS, Platform as a Service (PaaS, and Software as a Service (SaaS are similar to the aspirant qualities of AGSD as they provide services that are globally accessible, efficient, and stable, with lower predictable operating costs that scale to meet the computational demand. This study focused on the 12 agile principles upon which all agile methodologies are based, therein potentially increasing the potential for the findings to be generalized. Domestication Theory was used to assist in understanding how cloud technologies were appropriated in support of AGSD. The research strategy took the form of case study research. The findings suggest that some of the challenges in applying the agile principles in AGSD may be overcome by using CC.

    Maestas, Joseph H.

    2007-08-01

    Sandia networks consist of nearly nine hundred routers and switches and nearly one million lines of command code, and each line ideally contributes to the capabilities of the network to convey information from one location to another. Sandia's Cyber Infrastructure Development and Deployment organizations recognize that it is therefore essential to standardize network configurations and enforce conformance to industry best business practices and documented internal configuration standards to provide a network that is agile, adaptable, and highly available. This is especially important in times of constrained budgets as members of the workforce are called upon to improve efficiency, effectiveness, and customer focus. Best business practices recommend using the standardized configurations in the enforcement process so that when root cause analysis results in recommended configuration changes, subsequent configuration auditing will improve compliance to the standard. Ultimately, this minimizes mean time to repair, maintains the network security posture, improves network availability, and enables efficient transition to new technologies. Network standardization brings improved network agility, which in turn enables enterprise agility, because the network touches all facets of corporate business. Improved network agility improves the business enterprise as a whole.

    Pilgrim, Jeffrey S.; Bomse, David S.

    2006-01-01

    A prototype external-cavity diode laser (ECDL) has been developed for communication systems utilizing dense wavelength- division multiplexing (DWDM). This ECDL is an updated version of the ECDL reported in Wavelength-Agile External- Cavity Diode Laser (LEW-17090), NASA Tech Briefs, Vol. 25, No. 11 (November 2001), page 14a. To recapitulate: The wavelength-agile ECDL combines the stability of an external-cavity laser with the wavelength agility of a diode laser. Wavelength is modulated by modulating the injection current of the diode-laser gain element. The external cavity is a Littman-Metcalf resonator, in which the zeroth-order output from a diffraction grating is used as the laser output and the first-order-diffracted light is retro-reflected by a cavity feedback mirror, which establishes one end of the resonator. The other end of the resonator is the output surface of a Fabry-Perot resonator that constitutes the diode-laser gain element. Wavelength is selected by choosing the angle of the diffracted return beam, as determined by position of the feedback mirror. The present wavelength-agile ECDL is distinguished by design details that enable coverage of all 60 channels, separated by 100-GHz frequency intervals, that are specified in DWDM standards.

  5. Agent-based scheduling system to achieve agility

    Science.gov (United States)

    Akbulut, Muhtar B.; Kamarthi, Sagar V.

    2000-12-01

    Today's competitive enterprises need to design, develop, and manufacture their products rapidly and inexpensively. Agile manufacturing has emerged as a new paradigm to meet these challenges. Agility requires, among many other things, scheduling and control software systems that are flexible, robust, and adaptive. In this paper a new agent-based scheduling system (ABBS) is developed to meet the challenges of an agile manufacturing system. In ABSS, unlike in the traditional approaches, information and decision making capabilities are distributed among the system entities called agents. In contrast with the most agent-based scheduling systems which commonly use a bidding approach, the ABBS employs a global performance monitoring strategy. A production-rate-based global performance metric which effectively assesses the system performance is developed to assist the agents' decision making process. To test the architecture, an agent-based discrete event simulation software is developed. The experiments performed using the simulation software yielded encouraging results in supporting the applicability of agent-based systems to address the scheduling and control needs of an agile manufacturing system.

  8. Current State of Agile User-Centered Design: A Survey

    Science.gov (United States)

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    Agile software development methods are quite popular nowadays and are being adopted at an increasing rate in the industry every year. However, these methods are still lacking usability awareness in their development lifecycle, and the integration of usability/User-Centered Design (UCD) into agile methods is not adequately addressed. This paper presents the preliminary results of a recently conducted online survey regarding the current state of the integration of agile methods and usability/UCD. A world wide response of 92 practitioners was received. The results show that the majority of practitioners perceive that the integration of agile methods with usability/UCD has added value to their adopted processes and to their teams; has resulted in the improvement of usability and quality of the product developed; and has increased the satisfaction of the end-users of the product developed. The top most used HCI techniques are low-fidelity prototyping, conceptual designs, observational studies of users, usability expert evaluations, field studies, personas, rapid iterative testing, and laboratory usability testing.

    2011-01-01

    The development of functional legged robots has encountered its limits in human-made actuation technology. This paper describes research on the biomimetic design of legs for agile quadrupeds. A biomimetic leg concept that extracts key principles from horse legs which are responsible for the agile and powerful locomotion of these animals is presented. The proposed biomimetic leg model defines the effective leg length, leg kinematics, limb mass distribution, actuator power, and elastic energy recovery as determinants of agile locomotion, and values for these five key elements are given. The transfer of the extracted principles to technological instantiations is analyzed in detail, considering the availability of current materials, structures and actuators. A real leg prototype has been developed following the biomimetic leg concept proposed. The actuation system is based on the hybrid use of series elasticity and magneto-rheological dampers which provides variable compliance for natural motion. From the experimental evaluation of this prototype, conclusions on the current technological barriers to achieve real functional legged robots to walk dynamically in agile locomotion are presented.

  12. Agile Software Development Methods: A Comparative Review1

    Science.gov (United States)

    Abrahamsson, Pekka; Oza, Nilay; Siponen, Mikko T.

    Although agile software development methods have caught the attention of software engineers and researchers worldwide, scientific research still remains quite scarce. The aim of this study is to order and make sense of the different agile approaches that have been proposed. This comparative review is performed from the standpoint of using the following features as the analytical perspectives: project management support, life-cycle coverage, type of practical guidance, adaptability in actual use, type of research objectives and existence of empirical evidence. The results show that agile software development methods cover, without offering any rationale, different phases of the software development life-cycle and that most of these methods fail to provide adequate project management support. Moreover, quite a few methods continue to offer little concrete guidance on how to use their solutions or how to adapt them in different development situations. Empirical evidence after ten years of application remains quite limited. Based on the results, new directions on agile methods are outlined.

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

    This study was to investigate the impacts of senior brain heath exercise (SBHE) program for 12 weeks to basic active physical fitness, cognitive function and brain derived neurotrophic factor (BDNF) in elderly women. Subject of this study is total of 24 women in the age of 65-79 who can conduct normal daily activity and communication but have not participated in regular exercise in recent 6 months. The study groups were divided into an exercise group (EG, n=13) and a control group (CG, n=11). The exercise program was consisted of SBHE, and training frequency was 4 times weekly, of which training time was a total of 50 minutes each time in level of intensity of 9-14 by rating of perceived exertion (RPE). First, 12-week SBHE program has shown statistical increase in basic physical fitness in the EG comparing with the CG, such as lower body strength, upper body strength and aerobic endurance, but not in flexibility, agility and dynamic balance. Second, in the case of Mini-mental state examination Korean version (MMSE-K) and BDNF, it showed that there was a statistically significant increase in the EG comparing with the CG. In this study, 12-week SBHE program has resulted in positive effect on change of basic physical fitness (strength and aerobic endurance), cognitive function and BDNF. If above program adds movements that can enhance flexibility, dynamic balance and agility, this can be practical exercise program to help seniors maintain overall healthy lifestyle.

    2016-10-01

    Full Text Available Context: Globalization has affected all productive sectors and in particular the software industry, which has required the development of new methodologies to suit the speed of the changes and allow quickly build products that meet the requirements of the customers. On the other hand, the GPS technology, 4G connectivity and integration of social networks that have the most current mobile phones have opened a large field of application, particularly in the area of the transport, mobility and citizen complaint, whose development can be successfully addressed through an agile methodology. Method: Agile methodology Scrum was used for the development of a mobile application on the Android operating system and GPS technology, which allows a Bogota taxi user to monitor the route and send a complaint to the social network Twitter in case of nonconformity. Some UML models were used for analysis and design of the application, and a confidence interval was used to validate the results. Results: Prototype of a mobile taximeter developed with an agile methodology that meets quality characteristics, extensibility and maintainability. T-student distribution was used to validate the measurement of the prototype on 50 samples, concluding that the difference between the measurement of a real taximeter and our mobile taximeter is on average 2 units with a standard deviation of 1,39 units. Conclusions: It is shown that with the agile development can be combined with UML modeling tools and statistical validation techniques for quality products that do not violate, but on the contrary, that reaffirm the agile development principles.

    2008-01-01

    The aim of this study was to assess the relationships between various field tests in female athletes. Altogether, 83 high school soccer, 51 college soccer, and 79 college lacrosse athletes completed tests for linear sprinting, countermovement jump, and agility in a single session. Linear sprints (9.1, 18.3, 27.4, and 36.6 m) and agility tests (Illinois and pro-agility) were evaluated using infrared timing gates, while countermovement jump height was assessed using an electronic timing mat. Pearson's product-moment correlation coefficients (r) were used to determine the strength and directionality of the relationship between tests and coefficients of determination (r2) were used to examine the amount of explained variance between tests. All of the performance scores were statistically correlated with each other; however, the coefficients of determination were low, moderate, and high depending on the test pairing. Linear sprint split times were strongly correlated with each other (r= 0.775 to 0.991). The relationship between countermovement jump height and linear sprinting was stronger with the longer distances (27.4 and 36.6 m) than with the shorter distances (9.1 and 18.3 m), and showed a stronger relationship within the college athletes (r= -0.658 to -0.788) than high school soccer players (r= -0.491 to -0.580). The Illinois and pro-agility tests were correlated (r > or = 0.600) with each other as well as with linear sprint times. The results of this study indicate that linear sprinting, agility, and vertical jumping are independent locomotor skills and suggest a variety of tests ought to be included in an assessment protocol for high school and college female athletes.

    Agile concepts are not only beneficial for manufacturing sector but also for service sector such as healthcare. However, assessment of agility has been predominantly done in manufacturing enterprises. This study demonstrates a means to measure agility of a healthcare organization by assessing agility of a university dispensary. Its contribution to the knowledge base is twofold. First, it proposes a means to measure the agility of a healthcare organization and second, it identifies the attributes that prevent agile performance and outlines the suggestive measure to enhance its agile capabilities. A case study approach has been adopted and fuzzy logic has been employed to measure the agility of the case dispensary. At first, the measures of assessment which include four enablers, fifteen criteria and forty-five attributes have been identified from the literature and rated by the experts indicating the importance of the measures in the assessment. Then, the case dispensary has been assessed on those measures by collecting observed performance rating from decision makers. At last, Fuzzy logic has been applied on the performance rating data to analyze and interpret the agile capability of the dispensary. The findings suggest that transparent information flow, adequate salary and bonuses for caregivers, reading error in medical descriptions, in house/nearby pathology laboratory services, technical up-gradation of dispensary equipments and facilities, minimization of patient throughput time and adequate training programme for safety practices are the attributes that weakens agile capability of the University dispensary. The current agility of the dispensary was found to be 'Agile' which is average in relation to the agility labels. Attributes such as transparent information flow, adequate salary and bonuses for caregivers, elimination of reading error in medical descriptions, in house/nearby pathology laboratory services, technical up-gradation of dispensary equipments

    2014-08-15

    This paper describes HFE program development project conducted at a Finnish power company Fortum. The aim of developing a formal HFE program was to improve integration of human factors issues in design of technical systems and to systematically document the HFE process of the company. As Fortum has a long tradition of designing control room solutions, the starting point of the HFE program development was the existing own design practices. On the other hand, the aim was to create a program which would comply with international guidelines such as NUREG-0711. The program development was conducted by tracing the HFE design practices in an on-going I and C modernization project. This empirical work was carried out by interviews of designers and other HFE key stake holders. After the explication of the current practices, the gaps, overlaps and differences in relation to the international standards and guidelines were identified. Based on an analysis of current practices and guidelines and standards a new HFE process model was created. The design process model can be followed in modifications which concern systems with human user interfaces of any kind. The model consists of five separate phases which comply with the general engineering design process model utilized at the company. The HFE program is intended to be both a practical guide on how to take human factors issues into consideration in the design of NPP systems and also a tool for the management of HFE activities.

    The GMSEC (Goddard Mission Services Evolution Center) Services Suite (GSS) is a collection of tools and software services along with a robust customizable web-based portal that enables the user to capture, monitor, report, and analyze system-wide GMSEC data. Given our plug-and-play architecture and the needs for rapid system development, we opted to follow the Scrum Agile Methodology for software development. Being one of the first few projects to implement the Agile methodology at NASA GSFC, in this presentation we will present our approaches, tools, successes, and challenges in implementing this methodology. The GMSEC architecture provides a scalable, extensible ground and flight system for existing and future missions. GMSEC comes with a robust Application Programming Interface (GMSEC API) and a core set of Java-based GMSEC components that facilitate the development of a GMSEC-based ground system. Over the past few years, we have seen an upbeat in the number of customers who are moving from a native desktop application environment to a web based environment particularly for data monitoring and analysis. We also see a need to provide separation of the business logic from the GUI display for our Java-based components and also to consolidate all the GUI displays into one interface. This combination of separation and consolidation brings immediate value to a GMSEC-based ground system through increased ease of data access via a uniform interface, built-in security measures, centralized configuration management, and ease of feature extensibility.

One hundred eighty-seven players, divided into bi-annual age-groups, U12, U14, U16 and U18, performed two tests: Y-Agility Test, carried out in planned and reactive mode (Y-PLAN and Y-REAC) and Illinois for Change of Direction Test (ICODT). Difference between Y-REAC minus Y-PLAN represents the index of reactivity (REAC-INDEX). MANOVA showed significant differences among groups (F3,182=14.591; PTEST and ICODT, for the three categories of young players (0.398 Pskill level, whereas the best RA results depend on technique and experience that help the players to use anticipatory skill. The high correlations between CODS and RA performances, differently than adult athletes, suggest that an effective work program for young players may include RA and CODS training at the same time.

    The charter goal of the Agile Machining and Inspection Thrust Area Team is to identify technical requirements, within the nuclear weapons complex (NWC), for Agile Machining and Inspection capabilities. During FY 2008, the team identified Parametric Technology Corporation (PTC) Pro/CMM as a software tool for use in off-line programming of probing routines--used for measurement--for machining and turning centers. The probing routine would be used for in-process verification of part geometry. The same Pro/CMM program used on the machine tool could also be employed for program validation / part verification using a coordinate measuring machine (CMM). Funding was provided to determine the compatibility of the Pro/CMM probing program with CMM software (Zeiss DMISEngine).

    Full Text Available The main advantage of software defined networking (SDN is that it allows intelligent control and management of networking though programmability in real time. It enables efficient utilization of network resources through traffic engineering, and offers potential attack defense methods when abnormalities arise. However, previous studies have only identified individual solutions for respective problems, instead of finding a more global solution in real time that is capable of addressing multiple situations in network status. To cover diverse network conditions, this paper presents a comprehensive reactive system for simultaneously monitoring failures, anomalies, and attacks for high availability and reliability. We design three main modules in the SDN controller for a robust and agile defense (RAD system against network anomalies: a traffic analyzer, a traffic engineer, and a rule manager. RAD provides reactive flow rule generation to control traffic while detecting network failures, anomalies, high traffic volume (elephant flows, and attacks. The traffic analyzer identifies elephant flows, traffic anomalies, and attacks based on attack signatures and network monitoring. The traffic engineer module measures network utilization and delay in order to determine the best path for multi-dimensional routing and load balancing under any circumstances. Finally, the rule manager generates and installs a flow rule for the selected best path to control traffic. We implement the proposed RAD system based on Floodlight, an open source project for the SDN controller. We evaluate our system using simulation with and without the aforementioned RAD modules. Experimental results show that our approach is both practical and feasible, and can successfully augment an existing SDN controller in terms of agility, robustness, and efficiency, even in the face of link failures, attacks, and elephant flows.

    Research indicates that planned and reactive agility are different athletic skills. These skills have not been adequately assessed in male basketball players. To define whether 10-m-sprint performance and planned and reactive agility measured by the Y-shaped agility test can discriminate between semiprofessional and amateur basketball players. Ten semiprofessional and 10 amateur basketball players completed 10-m sprints and planned- and reactive-agility tests. The Y-shaped agility test involved subjects sprinting 5 m through a trigger timing gate, followed by a 45° cut and 5-m sprint to the left or right through a target gate. In the planned condition, subjects knew the cut direction. For reactive trials, subjects visually scanned to find the illuminated gate. A 1-way analysis of variance (P agility tests (r = .590-.860). The reactive left cut did not correlate with the planned tests. The reactive right cut moderately correlated with the 10-m sprint and planned right cut (r = .487-.485). The results reemphasized that planned and reactive agility are separate physical qualities. Reactive agility discriminated between the semiprofessional and amateur basketball players; planned agility did not. To distinguish between male basketball players of different ability levels, agility tests should include a perceptual and decision-making component.

  13. Computer vision challenges and technologies for agile manufacturing

    applicable to commercial production processes and applications. Computer vision will play a critical role in the new agile production environment for automation of processes such as inspection, assembly, welding, material dispensing and other process control tasks. Although there are many academic and commercial solutions that have been developed, none have had widespread adoption considering the huge potential number of applications that could benefit from this technology. The reason for this slow adoption is that the advantages of computer vision for automation can be a double-edged sword. The benefits can be lost if the vision system requires an inordinate amount of time for reprogramming by a skilled operator to account for different parts, changes in lighting conditions, background clutter, changes in optics, etc. Commercially available solutions typically require an operator to manually program the vision system with features used for the recognition. In a recent survey, we asked a number of commercial manufacturers and machine vision companies the question, 'What prevents machine vision systems from being more useful in factories?' The number one (and unanimous) response was that vision systems require too much skill to set up and program to be cost effective.

    Full Text Available This paper presents a description of an agile testing process in a medium size software project that is developed using Scrum. The research methods used is the case study were as follows: surveys, quantifiable project data sources and qualitative project members opinions were used for data collection. Challenges related to the testing process regarding a complex project environment and unscheduled releases were identified. Based on the obtained results, we concluded that the described approach addresses well the aforementioned issues. Therefore, recommendations were made with regard to the employed principles of agility, specifically: continuous integration, responding to change, test automation and test driven development. Furthermore, an efficient testing environment that combines a number of test frameworks (e.g. JUnit, Selenium, Jersey Test with custom-developed simulators is presented.

    Full Text Available The development of an enterprise architecture (EA in large organizations is complex. Thus, is important that the implementation of EA creates value in early stages of the process. This document contains a proposal of an EA framework design with agile approach based in TOGAF. This proposal is done with the objective to streamline the EA process. This framework presents a new design taking into account the current regulations, the target line of the organization and the principles proposed by the agile approach of EA. The objectives of each phase of the architecture development method ADM of TOGAF are matched with the requirements of the organization to extract only those that are aligned to the business. The deliverables proposed by TOGAF are analyzed with the goal to obtain, integrate and reduce the documentation in the implementation and modeling phases. This reduction allows more flexibility, less impact in the processes, reduction in development time and costs.

    The production and exploitation of industrial control systems differ substantially from traditional information systems; this is in part due to constraints on the availability and change lifecycle of production systems, as well as their reliance on proprietary protocols and software packages with little support for open development standards [1]. The application of agile software development methods therefore represents a challenge which requires the adoption of existing change and build management tools and approaches that can help bridging the gap and reap the benefits of managed development when dealing with industrial control systems. This paper will consider how agile development tools such as Apache Maven for build management, Hudson for continuous integration or Sonatype Nexus for the operation of "definite media libraries" were leveraged to manage the development lifecyle of the CERN UAB framework [2], as well as other crucial building blocks of the CERN accelerator infrastructure, such as the CERN Co...

  18. Preparing your Offshore Organization for Agility: Experiences in India

    Srinivasan, Jayakanth

    Two strategies that have significantly changed the way we conventionally think about managing software development and sustainment are the family of development approaches collectively referred to as agile methods, and the distribution of development efforts on a global scale. When you combine the two strategies, organizations have to address not only the technical challenges that arise from introducing new ways of working, but more importantly have to manage the 'soft' factors that if ignored lead to hard challenges. Using two case studies of distributed agile software development in India we illustrate the areas that organizations need to be aware of when transitioning work to India. The key issues that we emphasize are the need to recruit and retain personnel; the importance of teaching, mentoring and coaching; the need to manage customer expectations; the criticality of well-articulated senior leadership vision and commitment; and the reality of operating in a heterogeneous process environment.

    The graceful and agile movements of animals are difficult to analyze and emulate because locomotion is the result of a complex interplay of many components: the central and peripheral nervous systems, the musculoskeletal system, and the environment. The goals of biorobotics are to take inspiration from biological principles to design robots that match the agility of animals, and to use robots as scientific tools to investigate animal adaptive behavior. Used as physical models, biorobots contribute to hypothesis testing in fields such as hydrodynamics, biomechanics, neuroscience, and prosthetics. Their use may contribute to the design of prosthetic devices that more closely take human locomotion principles into account. Copyright © 2014, American Association for the Advancement of Science.

    Full Text Available In recent years user-centered design, participatory design and agile development have seen much popularity in the field of software development. More specifically, applying these methods to user groups with cognitive and motor disabilities has been the topic of numerous publications. However, neuropsychological assessment and training require special consideration to include therapists and brain-injured patients into the development cycle. Application goals, development tools and communication between all stakeholders are interdependent and outlined in a framework that promotes elements of agile development. The framework is introduced by example of a virtual reality cognitive assessment for patients with traumatic brain injuries. The assessment has seen a total of 20 iterations over the course of nine months including changes in task content, task difficulty, user interaction and data collection. The framework and development of the cognitive assessment are discussed.
