Abstract:

Objective: Fatigue is a common condition contributing to disability among older patients. We studied self-reported task-specific fatigue and its relation with mobility task performance among community-dwelling primary care patients. Method: Cross-sectional analysis of baseline demographic and health data from a prospective cohort study of 430 primary care patients aged 65 years or older. Fatigue was measured using the Avlund Mobility–Tiredness Scale. Performance tasks included rising from a chair, walking 4 m, and climbing two flights of stairs. Results: Among demographic and health factors, pain was the only attribute consistently predictive of fatigue status. Self-reported chair rise fatigue and walking fatigue were associated with specific task performance. Stair climb fatigue was not associated with stair climb time. Discussion: Pain is strongly associated with fatigue while rising from a chair, walking indoors, and climbing stairs. This study supports the validity of self-reported chair rise fatigue and walking fatigue as individual test items.

Abstract:

In view of the practical problems faced by the group with travel inconvenience, the wheelchairs in today’s Chinese market can’t meet the needs of society. Taking the integrated function chair as the research object, this paper puts forward the whole structure of the self-help ladder climbing intelligent chair. The chair is designed on the basis of analyzing the working principle of the main and the auxiliary structure. Based on Ergonomics, the composition and driving mode of each core module and auxiliary mechanism are developed, and the three-dimensional model of self-help ladder climbing intelligent chair is established by using UG. Selfhelp intelligent stair-climbing chair is not only conductive to improving the quality of life of special people and easing their family burden, but also has positive significance to the healthy and sustainable development of wheelchair industry.

Abstract:

AbstractParamedics face rising numbers of deployments every year. As obstacles like stairs occur often, paramedics must frequently manually carry patients and are thereby exposed to loads multitudes higher than recommended. This creates the need for patient transport aids (PTA), which can physically support paramedics in a wide variety of transport situations, without slowing down the transport. In this paper a workflow analysis for transport missions in an urban context and basic tasks for PTAs are presented. Subsequently, the high-level task modelling and human-centered risk analysis according to the HiFEM method are presented for the use case of a patient transport over stairs with a passive PTA, like a rescue chair, and an active PTA like the novel SEBARES prototype. The analysis shows that conventional PTA’s have a simple linear use process, however, impose excessive physical workloads, which cause risks like the paramedic or the PTA falling down the stairs. Contrary, active PTA’s reduce physical workloads, however, introduce additional concurrent steps, like identifying and correcting misalignments, which create further risks. In order to mitigate risks with active, stair climbing PTAs, either new kinematic designs or intelligent assistance functions, like automatic stair detection, are necessary.

Abstract:

The relationship between isometric force control and functional performance is unknown. Submaximal steadiness and accuracy were measured during a constant force-matching task at 50% of maximal isometric voluntary contraction (MVC) of the knee extensors in 19 older women (70–89 years). Other variables included MVC, rate of torque development, and EMG activity. Functional performance was assessed during maximal performance of walking endurance, chair rising, and stair climbing. Isometric steadiness (but not accuracy) was found to independently predict chair-rise time and stair-climbing power and explained more variance in these tasks than any other variable. Walking endurance was related to muscle strength but not steadiness. These results suggest that steadiness is an independent predictor of brief, stressful functional-performance tasks in older women with mild functional impairment. Thus, improving steadiness might help reduce functional limitations or disability in older adults.

Abstract:

Ageing, obesity and the metabolic syndrome (MetS) may all contribute to poor muscle health (sarcopenia). This study aimed to determine the cross-sectional associations between MetS (International Diabetes Federation classification) and sarcopenia (revised European Working Group on Sarcopenia in Older People definition) in 84 overweight and obese older adults. Components of sarcopenia included muscle strength (hand grip and leg extension), physical performance (stair climb test and short physical performance battery (SPPB), including gait speed and repeated chair stands time), muscle mass (appendicular lean mass (ALM), dual-energy X-ray absorptiometry), muscle size (peripheral quantitative computed tomography-determined calf and forearm cross-sectional area (CSA)) and muscle quality (muscle density and strength normalised to lean mass). Waist circumference was associated with greater muscle size, but poorer leg extension strength, chair stands and stair climb time, gait speed, SPPB scores and muscle quality measures (all p < 0.05). MetS was positively associated with ALM and forearm muscle CSA, and negatively associated with muscle quality measures and chair stands time (all p < 0.05). MetS is associated with larger muscle size, yet poorer muscle quality in overweight and obese older adults. Assessments of muscle function and quality should be considered for obese older adults and those with MetS.

Abstract:

Objective. To investigate the feasibility and effects of additional preoperative high intensity strength training for patients awaiting total knee arthroplasty (TKA).Design. Clinical controlled trial.Patients. Twenty-two patients awaiting TKA.Methods. Patients were allocated to a standard training group or a group receiving standard training with additional progressive strength training for 6 weeks. Isometric knee extensor strength, voluntary activation, chair stand, 6-minute walk test (6MWT), and stair climbing were assessed before and after 6 weeks of training and 6 and 12 weeks after TKA.Results. For 3 of the 11 patients in the intensive strength group, training load had to be adjusted because of pain. For both groups combined, improvements in chair stand and 6MWT were observed before surgery, but intensive strength training was not more effective than standard training. Voluntary activation did not change before and after surgery, and postoperative recovery was not different between groups (P>0.05). Knee extensor strength of the affected leg before surgery was significantly associated with 6-minute walk (r=0.50) and the stair climb (r−=0.58,P<0.05).Conclusion. Intensive strength training was feasible for the majority of patients, but there were no indications that it is more effective than standard training to increase preoperative physical performance. This trial was registered withNTR2278.

Abstract:

Wood inhabiting fungi oposes a great problem for preservation of wooden surfaces everywhere, being the main problem of economic losses of wooden products.

A reference collection consisting of 9 different genus constituting of 21 different strains of wood-inhabiting fungi was used for identification of unknown species of mould and blue stain fungi on wood. The fungus DNA from the samples was isolated from malt extract agar. PCR (Polymerase Chain Reaction) was conducted on rDNA ITS1 and ITS2 regions for amplification of the DNA. The 21 samples were collected to a reference collection for identification of unknown species of fungi on wooden field samples using PCR and T-RFLP (Terminal Restriction Fragment Length Polymorphism).

PCR-based methods, sequencing and T-RFLP were proven to be simple and

accurate methods for detection and identification of fungi in their early stage.

Abstract:

This thesis investigates the way to implement a valuable e-commerce solution. With the growing importance of information technologies in business practices, more and more companies are adopting e-commerce as a selling and ordering process. However, depending on the market environment, the level of success of the implementation may differ. The purpose of this study is therefore to examine what are the conditions required for a successful B2B e-commerce implementation in different market contexts.

Theories related to the impact of markets' contexts on e-commerce, the business process, and the drivers and enablers of e-commerce have been considered. Thereafter the current situation of Star Laundry Solutions (SLS) has been studied. The context of different markets – France, United Kingdom, Turkey - where they have dealers, the business process drivers of implementations and success factors of a valuable e-commerce solution have been investigated. The result of the empirical studied are analyzed in comparison with the theoretical findings. Through this method, the main research question of the thesis, namely “What are the necessary conditions to implement a value-adding e-commerce solution in different market contexts?” can be answered.

Several conditions have been identified in order to succeed the implementation and bring value to the different players along the supply chain, from the manufacturer to the end-customer. The market should first answer different criteria. Further, future users of the web solution must support the implementation, trust between parties must also emerge from the implementation, and additional information must be provided on the website such as product numbers (PNCs), products' availability and delivery times.

The provided recommendations of this thesis regarding the features of the web solution, the range of products that dealers and importers should be able to order online and the range of companies that should be allowed to use the web solution in Turkey.

Abstract:

Nokia scaled up remarkably quickly in the 1990s, faster than any producer of a complicated product ever had before. However, by 1995 Nokia had lost control of its supply chain, going through what it refers to as a “logistics crisis.” This chapter reviews and analyzes the factors that allowed extremely fast growth, and also discusses how Nokia was able to recover from the logistics crisis by bringing greater discipline to how Nokia Mobile Phones was run and greater sophistication to supply chain management. Nokia also created a New Venture organization with a mission to search for a “third leg,” beyond the successful Mobile Phones and Networks businesses. The chapter analyzes how these developments enabled the continuation of extraordinarily rapid growth through the late 1990s, but also sowed the seeds of later difficulties.

Abstract:

The evening star and its counterpart, the morning star, play important roles as generic markers in wedding poetry and love poetry. Poetic appearances of the stars commonly allude to at least one previous example, creating a chain of literary references across antiquity. These stars exert a powerful influence on human activities. In weddings, the evening star brings the bride to the groom, separates her from her family, and arouses mixed emotions of delight and fear. In love poetry, the evening star may unite lovers, but they are unavoidably separated by the morning star, herald of the dawn. The cyclical return of the stars is echoed by the tradition of refrains in wedding and love poetry. More commonly found in nuptial poetry, they can indicate allusions to the wedding song in erotic compositions and contain overtones of magic spells, particularly in the Latin tradition.

Full text

Abstract:

Proximal leg weakness is a common presentation in neuromuscular clinics. Hips flexion, abduction, adduction, and rotation are mainly achieved by iliopsoas, glutei, and obturator muscles. Hip pathology, especially when painless, may lead to diagnostic confusion that needs a good EMG of these muscles to be cleared. Most myopathies present with painless proximal leg weakness (difficulty climbing stairs and arising out of a deep chair). CIDP, diabetic amyotrophy, motor neuron diseases, and lumbar plexitis may all present similarly. Severe pain is typical of plexus pathology and is rarein myopathies. Students should be taught to avoid the assumption that proximal weakness is only caused by myopathies.

Full text

Abstract:

Spondylolysis is a stress fracture of the vertebral pars interarticularis that frequently affects adolescents involved in sports. Conservative bracing methods may assist the clinician in treating spondylolysis, though there is a need to further validate these techniques. The goal of this study was to evaluate differences in the 3D movements of the thoracic and lumbar spine before and after bracing. Five patients (mean age 14.4 ± 1.3 years) with spondylogenic back pain were evaluated for kinematic measurements using a Vicon motion capture system. Patients performed activities both with and without a lumbar corset brace including walking, kneeling, standing from a chair, standing from the floor, ascending and descending stairs, and lifting. Patients were evaluated for differences in thoracic and lumbar range of motion (ROM) in the braced and unbraced condition. While wearing the brace, patients demonstrated reduced extension ROM of the thoracic spine while walking (mean reduction = 0.4°), ascending stairs (3.0°), descending stairs (2.1°), lifting (14.8°), standing from a chair (4.1°), standing from the floor (16.7°), and kneeling (8.4°). Patients also exhibited reduced extension ROM of the total lumbar spine while ascending stairs (mean reduction = 1.8°), lifting (12.7°), standing from a chair (9.5°), standing from the floor (11.8°), and kneeling (4.7°). These results provide evidence that bracing reduces stress on the pars interarticularis and relieves symptoms in the athlete with spondylogenic back pain, thereby facilitating a return to sports.

On 18 September 1838, while Marmier was still in Sweden, he was appointed, in his absence, to the newly created chair of Foreign Literature at the University of Rennes. This was one of a number of new posts created in an expansion of provincial universities by an initiative of the Ministre de l'Instruction publique, Salvandy. Once back with his parents in Bourgfeld, Marmier learned with great satisfaction that Salvandy would allow him to spend the remainder of the year on sabbatical in Paris. After becoming bored with his post, he urged Gaimard to organise a new expedition. In his expedition in Spitzbergen, the things that struck Marmier most during his contacts with the local population were their hospitality, their honesty, their physical beauty, and their terrible poverty. On the whole, his comments about them are sympathetic and positive, although he condemns the treatment of animals there.

Abstract:

Congenital adrenal hyperplasia (CAH) represents a group of autosomal recessive disorders of steroidogenesis caused by defects in steroidogenic enzymes involved in glucocorticoid synthesis or in enzymes providing cofactors to steroidogenic enzymes (1, 2). Congenital lipoid adrenal hyperplasia (CLAH) caused by steroidogenic acute regulatory protein (StAR) deficiency is distinct in origin and presentation from the conventional variants of CAH, with the unique feature of lipid accumulation subsequently leading to destruction of adrenal function. This chapter will also mention aldosterone synthase deficiency, which is the only defect in adrenal steroidogenesis causing deficient mineralocorticoid biosynthesis without affecting glucocorticoid biosynthesis. The disorder cannot strictly be considered a CAH variant as it does not result in increased ACTH drive and thus not in adrenal hyperplasia. Novel forms of CAH have emerged during recent years. These include P450 oxidoreductase deficiency (ORD), P450 side-chain cleavage (CYP11A1) deficiency, the nonclassic form of CLAH (StAR deficiency), and apparent cortisone reductase deficiency. All forms of congenital adrenal hyperplasia resemble a disease continuum spanning from mild nonclassic presentations to classic onset with severe signs and symptoms.

This chapter talks about country music star Dolly Parton, who is also a poet at heart. She is an avid reader, with an extensive book collection. As a child growing up in Appalachia, however, Dolly experienced book hunger first-hand. It explains how Dolly's own childhood experience motivated her to found the Imagination Library as a way to ensure that all children could experience the joy of book ownership. The chapter also discusses other organizations like First Book that reinvents the traditional book supply chain. Rather than relying on for-profit bookstores as an intermediary, First Book and Imagination Library have innovated alternative, more cost-effective systems to deliver books to children from low-income backgrounds. Through a combination of charitable dollars and cost savings, innovative nonprofits are bringing books to millions of American children who otherwise could not afford them.

Abstract:

This case study focuses on the mid-size hotel industry in India. It will analyze the extent to which the pricing strategies are adopted in order to optimize revenues. The mid-size segment is comprised of three and four star hotels, which cater to the average foreign and domestic leisure travelers. Pricing is the single greatest challenge facing independent hotels today. It is studied how determining optimal rates based on the patterns of price sensitivity of demand still remains the biggest challenge for these hotels. Price sensitivity and its impact on revenue are examined. To determine and analyze this challenge faced by mid-size hotel industry, the case will focus on pricing strategies and challenges faced by a midscale chain hotel and a stand-alone economy hotel in New Delhi. The hotels have been taken from National Capital Region (New Delhi) which is the largest hotel market in the country both in terms of active assets under development and potential projects in planning.

Abstract:

Polyphosphazenes comprise by far the largest class of inorganic macromolecules. At least 700 different polymers of this type have been synthesized, with a range of physical and chemical properties that rivals that known hitherto only for synthetic organic macromolecules. Most polyphosphazenes have the general molecular structure. The polymer backbone consists of alternating phosphorus and nitrogen atoms, with two side groups, R, being attached to each phosphorus. The side groups may be organic, organometallic, or inorganic units. Each macromolecule typically contains from 100 to 15,000 or more repeating units linked end to end, which means that (depending on the organic side groups) the highest molecular weights are in the range of 2 million to 10 million. The bonding structure in the backbone is formally represented as a series of alternating single and double bonds. However, this formulation is misleading. Structural measurements suggest that all the bonds along the chain are equal or nearly equal in length, but without the extensive conjugation found in organic polyunsaturated materials. This anomaly will be discussed later. In addition to linear polyphosphazenes with one type of side group, other molecular architectures have also been assembled. These include polyphosphazenes in which two or more different side groups, R1 and R2, are arrayed along the chain in random, regular, or block distributions. Other species exist with short phosphazene branches linked to phosphorus atoms in the main chain. Also available are macromolecules in which carbon or sulfur replace some of the phosphorus atoms in the skeleton. Star-geometry structures, using the symbolism defined, are also accessible. A new and growing area is the field of phosphazene-organic and phosphazene-polysiloxane hybrid linear copolymers, and comb copolymers of the types. In addition, polymers are known in which six-membered phosphazene rings are side groups linked to organic polymers, and where phosphazene rings are linked by organic connector groups to form cyclolinear or cyclomatrix materials.

Abstract:

Knowledge of in vivo knee contact forces is essential for evaluating total knee replacement (TKR) designs. This is particularly true for activities other than walking, because there is still a limited understanding of its impact on wear. It has been shown that wear scars from retrieved implants have obvious differences compared with simulator tested components in both size of worn area and in damage mode. The divergence could be related to the omission of other activities than walking when testing components in the simulator. The purpose of this study was to use a parametric numerical model for predicting joint contact forces during stair ascent/descent and chair sitting/rising and compare those to measured forces from a database. We hypothesized that the contact force output of the numeric model would be similar to the measured forces.

Abstract:

Modeling and testing of the patello-femoral joint (PFJ) presents challenges in simulating the appropriate loading and kinematics. Walking is an activity of lower demand for patella performance. Higher demands occur during higher flexion activities such as stair ascending/descending, chair rising, and squatting. High patellofemoral joint reaction forces (PFJR) have been shown to begin around 60° of tibiofemoral flexion and remain high (2.5 × BW to 3.35 × BW) until approximately 110° of tibiofemoral (TF) flexion, at which point contact with soft tissue will tend to off-load the knee joint. Therefore, the flexion range of highest load for the patella is considered to be between 60° and 110° of TF flexion.

Abstract:

Our research object is to develop a wheel chair that is able to climb up and down stairs. Conventional wheel chairs use a parallel two-wheel type mobile base that is effective for moving on even surfaces but has limited clearance, posing difficulties in climbing over obstacles. In IROS2014, authors proposed and demonstrated an Octal Wheel unit that has 8 wheels with link-mechanisms and is able to climb up and down stairs. This robot is just a prototype to show the effectiveness of the mechanism. This research has begun to develop an AR chair that is able to carry a passenger, move autonomously, and climb up and down stairs. The first step of the AR chair project is to develop and construct a wheel chair with a center articulated body. The 8-wheel mechanism is applied to the AR chair model after the construction of an autonomous system. A control system with 3D LIDAR was installed on the prototype and it autonomously moved 1.4km in the Real World Robotics Challenge (RWRC) 2014 in Tsukuba on the official pedestrian road. Experimental results demonstrate the effectiveness of this method.

Abstract:

Abstract Assessment of corroded mooring chain for continued service is a challenging task faced by industry. Current best practice relies heavily on qualitative inspection information collected during inspection campaign. There has been little investigation into this practice and whether it is an appropriate technique or can be improved. To address this issue, the Fatigue of Corroded Mooring Chains (FoCCs) Joint Industry Project (JIP), initiated in 2016 with fifteen (15) participating organizations, including oil majors, chain manufactures, consulting firms, and classification societies, to examine assessment methods for evaluating remaining fatigue life. JIP teams were formed to progress fatigue testing and finite element objectives. One such team, comprised of ExxonMobil, ABS and Asian Star Anchor Chain, has performed an additional series of fatigue tests beyond the core JIP work effort. A fatigue test was conducted to 1) demonstrate the utility of finite element analysis in the assessment of fatigue life and 2) demonstrate performance of simulated damage. This unique fatigue test program was conducted on mooring chain with manufactured “corrosion pits” of different dimensions. All chain surface features were digitally recorded and converted into finite element models. These models were subsequently analyzed to compare with test results — both cycle count and failure location. This paper presents the findings from these fatigue tests and finite element analyses and how they can be utilized for assessment of remaining fatigue life.

Abstract:

This paper provides a new technique to assist patients during gait rehabilitation and safety support during exercise. The device can also be used by patients who have experienced physical trauma, and in need of assistance so that they can regain the strength needed to support them during rehabilitation. The procedure results in an adjustable gait rehabilitation lifting system and has the ability to support the weight of the user. The apparatus can lift a patient from a sitting position in a wheel chair to a standing position and has the provisions to remove a percentage of the patient’s body weight and recognize subtle changes in elevation. The patient requiring gait rehabilitation would be free to traverse a flat plane and climb a number of stairs and at the same time does not impede free walking and prevents sudden fall of the patient.

Abstract:

Recent advances in predictive dynamics allow the user to not only predict physics based human motion simulations but also determine the actuation torques required to achieve those motions. The predictive dynamics approach uses optimization to predict motion while using many task based, physics based, and environment based constraints including the equations of motion. Many tasks have been simulated using this new method of predicting and simulating digital human motion, e.g. walking, running, stair climbing, and box lifting. In this research, we develop a method to predict the motion as well as effect of external equipment hanging on the digital human. The proposed method is tested on a simple case of a two degree of freedom serial chain mechanism with a simple passive system to behave as external equipment. In particular, the passive mass is assumed to be attached to the two links system with a spring and damper. The results of the proposed method are compared with the results obtained by integrating the equations of motion of the full three degree of freedom system.
