Published: October 2015

Real time data acquisition and evaluation are required to save lives. Such data with utilization and application of the latest technologies in hospitals around the world can improve patient treatments and well beings. The delivery of patient's medical data needs to be secure. Secure and accurate real time data acquisition and analysis of patient data and the ability to update such data will assist in reducing cost while improving patient's care. A wireless framework based on radio frequency identification (RFID) can integrate wireless networks for fast data acquisition and transmission, while maintaining the privacy issue. This chapter discusses the development of a framework that can be considered for secure patient data collection and communications in a hospital environment. A new method for data classification and access authorization has also been developed, which will assist in preserving privacy and security of data. Several Case studies are offered to show the effectiveness of this framework.

Published: October 2015

Modern production technology comprises automatic devices with numerically controlled driving axes in a large extent. Those devices – so called CNCs - are financially available not only to large factories but to small and medium enterprises as well. When selecting the CNC machine to be purchased, ratio between the financial aspects and the machine performance is evaluated very thoroughly. This brings a constant pressure on CNC machines producers who seek for modern approaches enhancing performance of their products. The following paper introduces some theoretical aspects dealing with the positioning accuracy of numerically controlled axes.

Published: October 2015

In this manuscript, we have investigated the influence of radiation absorption on an unsteady MHD convective heat and mass transfer flow of a Newtonian fluid past a vertical porous plate in the presence of thermal radiation and chemical reaction. The non dimensional governing equations have been solved by using a multiple perturbation method, subject to the corresponding boundary conditions. The effects of various physical parameters such as velocity, temperature and concentration are studied through graphs. The expressions for local skin friction, Nusselt number and Sherwood number are derived and discussed with the help of a table. It is noticed that velocity increases when an increase in modified Grashof number Gm, radiation absorption parameter χ, Sorret number S0, time t whereas it decreases when an increase in Schmidt number Sc, chemical reaction parameter Kr and radiation parameter F. Temperature increases with an increase in radiation parameter χ and Sorret number S0whereas it decreases with an increase in chemical reaction parameter Kr, F and ϕ. Concentration is observed to be decreased when chemical reaction parameter Kr and Schmidt number Sc increase whereas it increases with an increase in Sorret number S0. Skin friction increases with an increase modified Grashof number Gm, radiation parameter χ and Sorret number S0whereas it has reverse effect in the case of Schmidt number Sc, chemical reaction parameter Kr. Nusselt number increases with an increase in Sc, S0, χ whereas it has reverse effect in the case of Kr. Sherwood number gets decreased when Sc, χ and Kr both are increased whereas it has shown revere effect in the case of S0.

Silica nanotubes with controlled diameter and length were synthesised by using a novel and modified template-sol-gel method. The consistency and order of silica nanotubes mainly depend on the anodic alumina membrane (AAO) template that was used during the preparation process. The AAO membrane was chemical etched using different concentrations (5, 7 and 10 wt %) of phosphoric acid. The obtained silica nanotubes had diameters in the range of 220-280 nm and thicknesses around 70-90 nm as observed by field emission scanning electron microscopy (FE-SEM). Scanning transmission electron microscopy (STEM) images enable us to view the arrangement of the hollow cylindrical silica nanotubes. Porosity of the silica nanotubes was investigated by nitrogen adsorption-desorption. The mesoporous silica nanotubes show characteristic type IV isotherm behaviour, with double capillary condensation step in the relative pressure range of 0.2-1.0 (p/p0). Thermogravimetric (TGA) and differential thermal (DTA) analyses confirm the thermal stability of the silica nanotubes and their weight changes and endo and exothermic reactions. The structural and functional group analyses of the silica nanotubes were carried out by using X-ray diffraction (XRD) patterns and Fourier transform infrared spectroscopy (FT-IR).

Authors: Pour Ali Nakhaei , Modaresi Seyed Majed
Published: October 2015

Concepts of the surface excess energy in the present work have been applied to explain the methane formation in Fischer-Tropsch synthesis by iron catalysts. A series of iron oxide particles doped by adding copper and lanthanum were prepared as a catalyst via precipitation by microemulsion method. Size dependent kinetic expressions for methane formation were derived and evaluated using experimental results. Experimental results show that the methane formation is increased by decreasing the catalyst particle size. The value of surface tension energy (σ) for iron catalyst is calculated in range of 0.047-0.015 J/m2in methane formation mechanism. This value is lower than iron metal and is referred to the presence of iron carbide and gas phase in this catalytic reaction. With a series of complicated mechanisms, methane is produced on the surface of catalyst and in the gas phase as well, this would be elaborated by following paragraphs, thus we can conclude that surface tension of catalyst has less effect on these reactions.

Tuberculosis is still a major global health concern, causing the estimated death of 1.5 million people per year and being associated with high morbidity. The development of point-of-care diagnostic tools for tuberculosis is mandatory, especially because the fast and accurate detection of the slow-growing Mycobacterium tuberculosis by the conventional diagnostic tests is difficult.The objective of this work was to develop the first steps to achieve a portable method for the diagnosis of tuberculosis, by a sandwich-immunoassay combined with magnetoresistive biochip technology.With the purpose of conjugating 250 nm streptavidin-coated magnetic nanoparticles with anti- M.tuberculosis biotinylated antibodies, Mycobacteriumbovis Bacillus Calmette-Guérin was used as a surrogate for M. tuberculosis bacteria. After magnetic capture, target bacteria were brought in contact with the surface of the magnetoresistive biochip previously functionalized with a secondary anti-M. tuberculosis antibody. Magnetically labeled cells were detected by an array of spin-valve sensors, which change their electrical resistance in the presence of the fringe field of the magnetic particles. Optimization studies on the efficiency of the magnetic capture and further recognition of the bacteria by the secondary antibody on the biochip surface were conducted. The results on the magnetoresistive biochip showed a clear difference in the signal between specific and control (non-specific) sensors, suggesting the usefulness of this technique as a potential biorecognition tool for the development of a point-of-care diagnostic method for tuberculosis.

In order to study the pavement performance of the soil that improved by ionic liquid soil stabilizer, the red-brown clay was concerned as the typical soil, mixed with the ionic soil stabilizer, the ordinary Portland cement and the hydrated lime, was tested to characterize its durability. The engineering classification of the typical soil was determined and the physical parameters of the ionic soil stabilizer was obtained, according to tests of the particle size analysis, crucial water content coefficient, organic matter content, PH, conductivity, plasma emission spectra, etc. In addition, the tensile strength, durability and shrinkage property were analyzed by split tests, freezing and thawing tests, fatigue tests and shrinkage tests. As a result, the typical soil was a kind of low liquid-limit clay, denoted by CL. The ionic soil stabilizer was a water soluble, high conductivity, strongly acidic sulfonated oleoresin. The ion exchange reaction between the soil and the ionic soil stabilizer begun after treating by the ionic soil stabilizer, and then the role of soil particles became stronger. Furthermore, the void between soil particles was decreased, the structure became closer, and then the tensile strength, durability and shrinkage property were improved. As mentioned above, the research provided theoretical foundation and practical support for using the ionic soil stabilizer in China's highway construction.

Authors: Luo Xiao Hua , Yang Qing , Qiu Xin , Xiao Shang Lin
Published: October 2015

Asphalt mixtures have a highly sensitive and dependent on temperature. The typical modulus values of asphalt mixtures vary dramatically at different temperatures. Therefore, adjusting the modulus values of asphalt pavements of different testing temperatures to that of the criterion temperature condition is an important task to sustain asphalt mixtures modulus based the structural bearing capacity estimation of asphalt pavements comparable between time and space. According to the dynamic finite element numerical analysis method and the multivariate nonlinear regression analysis technique, the paper firstly established the back calculation model of asphalt mixtures modulus in term of the relationship between asphalt moduli and deflection basin parameters. Secondly, considering the correlation between the temperature at the middle of asphalt wearing course and the asphalt mixture modulus, the conversion analysis procedure of asphalt mixtures moduli of different temperatures was presented based on BELLS3 temperature adjustment coefficient method. Finally, the in-service monitoring over the existing pavements was conducted to test the validity of the procedure. The research provides a practical basis for evaluating pavement performance of asphalt wearing mixtures and a theory support for overlaying thickness design of asphalt pavements.

Global Stability Analysis on Combination Self-Excited Vibration of BTA Deep-Hole Boring Rotor Materials
Authors: Zhao Wu , Hu Zhan Qi , Huang Dan
Published: October 2015

Cr, Ni, Mo, V exist in materials of high, medium and low pressure turbine rotor. Its composition contains higher carbon content, so leads to poor hardenability. Shear characteristics of martensite phase transformation is caused by a large number of micro defects inside crystal of microstructure in rotor during the service status. Martensite phase transformation is by strengthening because of plastic deformation in cutting process. Mechanical properties and phase transformation plasticity in cutting process show that rotor is hard machining material. Plastic deformation aggravates tool wear, and leads to an increased cutting force; hard points of uneven material internal organization lead to fluctuation of cutting force, and induced cutting chatter. During the course of machining critical or ultra-supercritical rotor, boring bar becomes a flexible system surrounded by rotating stirred vortex cutting fluid inside and outside it. BTA processing system is in a complicated hydraulic-solid coupling environment. Whether or not BTA deep hole boring processing system is stable, the essence is converted into estimating dynamic stability of BTA boring bar coupled fluid--solid with multi-physics environment. The system will be triggered cutting chatter, fluid flutter and self-excited vibration combination. This paper establishes nonlinear mathematical physics model on BTA deep hole processing system. The perturbation equation and Lyapunov function of BTA system are obtained, through introducing the stable Rumjantsev part variables analysis theory. Based on stability characteristic under the significance of Lyapunov, the constraint condition undisturbed stability is gotten and the global bifurcation analysis is finished. Hyperbolic periodic orbit and heteroclinic connection are found throughout the entire phase space of Hamiltonian system. The bifurcation condition on quadratic heteroclinic is acquired, by analyzing intersection relationship between hyperbolic stable manifold and its unstable manifold of Poincare mapping. The intersection critical conditions are shown on hyperbolic fixed stable manifold and its unstable manifold, by using computer numerical simulation to draw 3-D surface relationship among resonant frequency, cutting fluids flow velocity and the radius of free surface. The result could provide a reference on multi-machining parameters optimization for BTA deep hole boring process practical production.

Authors: Balestroni Gianluigi , Omarini Giovanna , Omarini Pierangela , Pistono Massimo , Corrà Ugo , Gnemmi Marco , Giannuzzi Pantaleo
Published: October 2015

Background: Advanced heart failure is a challenging disease; the implantable Left Ventricular Assist Device (L-VAD) is becoming a good chance for relieving symptoms and prolong survival in most CHF patients. The emotional impact of L-VAD implantation is thought to be high but, at present, published data are scant about that. Aim of this study was to evaluate the modifications of perceived quality of life (QoL) in a group of patients recently treated with L-VAD implantation, admitted to a residential cardiac rehabilitation program, and to compare the results to those obtained in patients awaiting heart transplantation and recently transplanted. Material and Method: We enrolled 66 patients (pts) with a recent implant of L-VAD, 51 with refractory heart failure awaiting heart transplantation (HT) and 55 recently treated with HT. On day two after admission, all patients underwent a complete psychometric assessment consisting in the compilation of: – Minnesota Living with Heart Failure Questionnaire (MLHFQ) – Beck Anxiety Inventory (BAI) – Beck Depression Inventory-II (BDI - II) Results: L-VAD recipients had significantly higher scores at MLHFQ. Both the total score and the 2 subscales scores (respectively physical and emotional disturbances) were statistically significant when compared with posttransplant patients. Post- transplant pts had the lowest scores regarding anxiety symptoms, while the bearers of device had the highest ones. The same results were obtained for depression scores (BDI - II), both in total score and in the subscales (somatic symptoms and affective symptoms). Conclusions: With an opening scoring, this study showed the development of more relevant psychological troubles in patients treated with L-VAD when compared to those awaiting for heart transplantation and those transplanted.
An Existence Theory for Incomplete Designs
Authors: Dukes Peter , Lamken Esther R. , Ling Alan C. H.
Published: October 2015

An incomplete pairwise balanced design is equivalent to a pairwise balanced design with a distinguished block, viewed as a ‘hole’. If there are v points, a hole of size w, and all (other) block sizes equal k, this is denoted IPBD((v;w), k). In addition to congruence restrictions on v and w, there is also a necessary inequality: v > (k − 1)w. This article establishes two main existence results for IPBD((v;w), k): one in which w is fixed and v is large, and the other in the case v > (k −1+∊)w when w is large (depending on ∊). Several possible generalizations of the problemare also discussed.

Aim

This study evaluated the effect of ultrasonic vibration on the tensile strength required to remove intraradicular post cemented with different materials.

Materials and methods

Bovine teeth were selected, and 7 mm of the cervical root canals were prepared to size 5 Largo drill, the posts were cemented with zinc phosphate, Enforce (resin) or Rely X (glass ionomer). The specimens were divided into six groups (n = 10), according to the following procedures: GI—cementation with zinc phosphate associated with traction force; GII—cementation with zinc phosphate associated with ultrasonic activation and traction force; GIII—cementation with Enforce associated with traction force; GIV—cementation with Enforce associated with ultrasonic activation and traction force; GV—cementation with Rely X associated with traction force; and GVI—cementation with Rely X associated with ultrasonic activation and traction force. The tensile test was conducted using the electromechanical testing machine, the force was determined by a specialized computer program and ultrasonic activation using the Jet Sonic Four Plus (Gnatus) device in 10P.

Results

Concerning to average ranking, GI showed statistically significant difference in comparison with GII and GVI (p < 0.05); there was no statistical difference in GIII and GIV when compared to other groups (p > 0.05).

Conclusion

The ultrasound favored the intraradicular post traction regardless of the employed cement in greater or lesser extent.

Clinical significance

The post removal is a routine practice in the dental office, therefore, new solutions and better alternatives are need to the practitioner. We did not find in the literature many articles referring to this practice. Thus, the results from this study are relevant in the case planning and to promote more treatment options.

Orthognathic Surgery in a Patient with Multiple Sclerosis
Authors: Al-Bazie Saleh A
Published: October 2015

Aim

The aim of this paper was to report a case of orthognathic surgery successfully done in a patient with multiple sclerosis.

Background

Multiple sclerosis (MS) is a chronic, progressive inflammatory disorder of the central nervous system affecting young adults, characterized by lymphocytic infiltration of the brain and spinal cord leading to demyelination and focal axonal damage. Clinically, MS patients present with reversible neurological dysfunction in the early stages, which progresses to irreversible neurological disability and deficit. Oral manifestations of MS include facial numbness or pain, neuralgias, facial paralysis, dysarthria and dysphagia. While dental treatment is not contraindicated in MS patients, it is, however, limited to preventive and supportive dental care.

Case description

A 23-year-old Saudi male patient with a diagnosis of MS since 2008 reported to the oral and maxillofacial surgery (OMFS) department for correction of dentofacial deformity. The patient was under follow-up with the neurology department and was being treated with interferon beta-1a. Following consent from the neurologist and the patient, a Lefort 1 segmental osteotomy was done under general anesthesia. The patient was stable throughout the surgical procedure and during the postoperative period. The patient was discharged upon complete surgical recovery and no acute exacerbations of MS were reported during the perioperative period.

Conclusion

Based on our observations, orthognathic and maxillofacial surgical procedures can be safely carried out in patients with MS, provided a strict perioperative prophylactic regimen for stress reduction and prevention of acute attacks of MS is adhered to.

Clinical significance

Due to the stressful nature of dental treatment and oral and maxillofacial surgical procedures, acute exacerbations of MS are very much likely. Hence, it is imperative that dental and oral surgical practitioners are aware of the manifestations of MS and are able to manage such patients with suitable treatment modifications.

Dehydration effects from contrails in a coupled contrail–climate model
Authors: Schumann U. , Penner J. E. , Chen Yibin , Zhou Cheng , Graf K.
Published: October 2015

Abstract. The uptake of water by contrails in ice-supersaturated air and the release of water after ice particle advection and sedimentation dehydrates the atmosphere at flight levels and redistributes humidity mainly to lower levels. The dehydration is investigated by coupling a plume-scale contrail model with a global aerosol–climate model. The contrail model simulates all the individual contrails forming from global air traffic for meteorological conditions as defined by the climate model. The computed contrail cirrus properties compare reasonably with theoretical concepts and observations. The mass of water in aged contrails may exceed 106 times the mass of water emitted from aircraft. Many of the ice particles sediment and release water in the troposphere, on average 700 m below the mean flight levels. Simulations with and without coupling are compared. The drying at contrail levels causes thinner and longer-lived contrails with about 15 % reduced contrail radiative forcing (RF). The reduced RF from contrails is on the order of 0.06 W m−2, slightly larger than estimated earlier because of higher soot emissions. For normal traffic, the RF from dehydration is small compared to interannual variability. A case with emissions increased by 100 times is used to overcome statistical uncertainty. The contrails impact the entire hydrological cycle in the atmosphere by reducing the total water column and the cover by high- and low-level clouds. For normal traffic, the dehydration changes contrail RF by positive shortwave and negative longwave contributions on the order of 0.04 W m−2, with a small negative net RF. The total net RF from contrails and dehydration remains within the range of previous estimates.
Modeling micro-topographic controls on boreal peatland hydrology and methane fluxes

Published: October 2015

Abstract. Small-scale surface heterogeneities can influence land-atmosphere fluxes and therefore carbon, water and energy budgets on a larger scale. This effect is of particular relevance for high-latitude ecosystems, because of the great amount of carbon stored in their soils. We introduce a novel micro-topographic model, the Hummock-Hollow (HH) model, which explicitly represents small-scale surface elevation changes. By computing the water table at the small scale, and by coupling the model with a process-based model for soil methane processes, we are able to model the effects of micro-topography on hydrology and methane emissions in a typical boreal peatland. In order to assess the effect of micro-topography on water the balance and methane emissions of the peatland we compare two versions of the model, one with a representation of micro-topography and a classical single-bucket model version, and show that the temporal variability in the model version with micro-topography performs better if compared with local data. Accounting for micro-topography almost triples the cumulative methane flux over the simulated time-slice. We found that the single-bucket model underestimates methane emissions because of its poor performance in representing hydrological dynamics. The HH model with micro-topography captures the spatial dynamics of water and methane fluxes, being able to identify the hotspots for methane emissions. The model also identifies a critical scale (0.01 km2) which marks the minimal resolution for the explicit representation of micro-topography in larger-scale models.
Resource acquisition, distribution and end-use efficiencies and the growth of industrial society
Authors: Jarvis A. J. , Jarvis S. J. , Hewitt C. N.
Published: October 2015

Abstract. A key feature of the growth of industrial society is the acquisition of increasing quantities of resources from the environment and their distribution for end-use. With respect to energy, the growth of industrial society appears to have been near-exponential for the last 160 years. We provide evidence that indicates that the global distribution of resources that underpins this growth may be facilitated by the continual development and expansion of near-optimal directed networks (roads, railways, flight paths, pipelines, cables etc.). However, despite this continual striving for optimisation, the distribution efficiencies of these networks must decline over time as they expand due to path lengths becoming longer and more tortuous. Therefore, to maintain long-term exponential growth the physical limits placed on the distribution networks appear to be counteracted by innovations deployed elsewhere in the system, namely at the points of acquisition and end-use of resources. We postulate that the maintenance of the growth of industrial society, as measured by global energy use, at the observed rate of ~ 2.4 % yr−1 stems from an implicit desire to optimise patterns of energy use over human working lifetimes.
Geochemical study on hot-spring water in West New Britain Province, Papua New Guinea
Authors: Lahan M. M. , Verave R. T. , Irarue P. Y.
Published: October 2015

Abstract. West New Britain Province, which occupies the western part of New Britain Island in Papua New Guinea, is ideally located within an active tectonic region that influences volcanism creating an environment favourable for geothermal activity. Geothermal mapping of surface manifestations reveals high temperature geothermal prospects along the northern coastline of West New Britain Province that are further confirmed by geochemical analysis. The occurrence of geothermal features is confined to the Quaternary Kimbe Volcanics and alluvium in the lowland areas. The features in Talasea appear to be controlled by deep-seated northerly trending faults while structures in Hoskins also appear to be deep seated but have not been identified. The geothermal systems in West New Britain Province have not been drilled, but preliminary reconnaissance geothermal mapping and geochemical analysis reveals four high temperature geothermal prospects suitable for further investigation and development of geothermal energy. These are the Pangalu (Rabili) and Talasea Station geothermal prospects in Talasea and Kasiloli (Magouru) and Silanga (Bakama and Sakalu) geothermal prospects in Hoskins. The calculated reservoir temperatures for these fields are in the range of 245–310 °C. Recommendations are made for further follow-up exploratory investigations.
Statistical model for economic damage from pluvial flood in Japan using rainfall data and socio-economic parameters
Authors: Bhattarai R. , Yoshimura K. , Seto S. , Nakamura S. , Oki T.
Published: October 2015

Abstract. The assessment of flood risk is important for policy makers to evaluate damage and for disaster preparation. Large population densities and high property concentration make cities more vulnerable to floods and having higher absolute damage per year. A number of major cities in the world suffer from flood inundation damage every year. In Japan, approximately JPY 100 billion in damage occurs annually due to pluvial flood only. The amount of damage was typically large in large cities, but regions with lower population density tended to have more damage per capita. Our statistical approach gives the probability of damage following every daily rainfall event and thereby the annual damage as a function of rainfall, population density, topographical slope, and gross domestic product. Our results for Japan show reasonable agreement with area-averaged annual damage for the period 1993–2009. We report a damage occurrence probability function and a damage cost function for pluvial flood damage, which makes this method flexible for use in future scenarios and also capable of being expanded to different regions.

Published: October 2015

Jaunesniame mokykliniame amžiuje formuojasi vaiko asmenybė, sveikos gyvensenos įpročiai, įgyjamos žinios. Todėl labai svarbu sveikos ir saugios gyvensenos pagrindus padėti jau ankstyvoje vaikystėje. Šeima – svarbiausia vaiko artimiausios aplinkos dalis, formuojanti jo elgseną ir gyvenseną. Darbo tikslas – ištirti jaunesniojo mokyklinio amžiaus vaikų gyvensenos ir sveikatos stiprinimo šeimoje ypatumus. Taikyta apklausa raštu. Tyrime dalyvavo 530 tėvų, kurių vaikai mokosi 1-3 klasėse (7- 9 metų). Nustatyta, kad dauguma tėvų savo vaiko sveikatą linkę vertinti kaip labai gerą arba gerą. Tik apie penktadalio šeimų, auginančių jaunesniojo mokyklinio amžiaus vaikus, gyvenimo būdas aktyvus. Didelė tėvų dalis vaikų fizinei sveikatai stiprinti renkasi vitaminus bei maisto papildus, daugiau kaip pusė respondentų grūdina savo vaikus ir skatina judėti. Vaikų psichinės sveikatos puoselėjimo būdais dažniausiai įvardijami bendravimas su vaiku ir bendras iškilusių problemų sprendimas. Darbo dienomis dauguma vaikų judriems žaidimams ir sportui lauke skiria 1-2 val., savaitgaliais šiai veiklai skiriama daugiau laiko. Prie kompiuterio ar televizoriaus iki 1 val. darbo dienomis praleidžia apie penktadalis mokinių, o savaitgaliais praleidžiamo laiko trukmė ilgėja. Apie penktadalis mokinių visada laikosi dienotvarkės. Šiek tiek daugiau negu pusės jaunesniojo mokyklinio amžiaus vaikų miego pradžia darbo dienomis yra 20-21 val. Savaitgaliais vaikų miego pradžios laikas vėlinamas. Savaitgaliais labai maža vaikų dalis eina miegoti tuo pačiu metu kaip ir darbo dienomis.

Published: October 2015

Gigantinių ląstelių navikai (toliau GLN) yra gerybiniai navikai, bet turintys agresyvų vietinį kaulų pažeidimą. Liga dažniausiai pasireiškia stiprėjančiu skausmu, vietiniu patinimu ir labai dažnai atraminių funkcijų praradimu ar sutrikimu.Vietinis naviko gydymas yra GLN kertinis gydymas. Naviko kontrolė dažniausiai priklauso nuo to, kaip radikaliai buvo pašalintas navikas. Tačiau galūnių funkcijų išsaugojimas ir geri ilgalaikiai gydymo rezultatai yra įmanomi taikant intranavikinį kiuretažą su pridėtiniu vietiniu gydymu. Dažnai pirminiai GLN yra neoperabilūs, todėl tenka taikyti kitus lokalius gydymo metodus – spindulinę terapiją ar sisteminį gydymą denosumabu. Sudėtinga radiologinė ir patologinė diagnostika leidžia daug tiksliau nustatyti naviko agresyvumą, numatomą chirurginės intervencijos apimtį bei prognozę. Retais atvejais GLN gali transformuotis į agresyvias sarkomas ar metastazuoja į plaučius.

Authors: Zakarienė Rasa
Published: October 2015

Straipsnis supažindina su slaugytojų komandos sutelktumo ugdymo prielaida ir varomąja jėga, kaip vienos iš esminių veiklos iššūkių, taip užtikrinant sėkmingas valdymo galimybes, konkurencingumą ir nuolatinį tobulėjimą. Slaugytojų komandinės veikos sutelktumui įvertinti buvo pasirinkta pasitikėjimo komanda skalė (angl. Team Trust Scale), kuri išversta iš anglų kalbos, adaptuota ir pritaikyta šiame darbe. Tyrimo metu apklausus slaugytojus, dirbančius stacionaro skyriuose, nustatyta, kad tarpusavio pasitikėjimas, tai veiksnys, turintis įtakos slaugytojų komandinės veiklos efektyvumui ir sutelktumui užtikrinti bei padedantis teikti kokybiškas slaugos paslaugas. Atlikto empirinio tyrimo rezultatai parodė, kad slaugytojai pasitiki savo komandos nariais, padeda vieni kitiems, laikosi duoto žodžio, nuolat aptaria klaidas ir neatitiktis, žino savo vaidmenis ir funkcijas, dalyvauja sprendimų priėmimuose, dalinasi atsakomybe ir yra įsitikinę, kad jų komanda dirba efektyviai ir sutelktai, nes tai parodo pacientų atsiliepimai. Pasiekti slaugytojų komandinio darbo rezultatai inspiruoja pasitenkinimą, formuoja pozityvų savęs vertinimą, kuris nulemia pasitikėjimą komandos nariais bei veiklos sutelktumą.

Tyrimo problema. Sveikatos priežiūros organizacijoms būtina formuoti kompetentingas, efektyviai veikiančias komandas, užtikrinančias tinkamą sveikatos priežiūros kokybės valdymą. Siekiant padidinti darbo efektyvumą bei užtikrinti slaugytojų komandos sutelktumą, tampa aktualu sukaupti pakankamai mokslinių duomenų, kurie padėtų išsiaiškinti svarbiausias kliūtis siekyje būti vieninga ir darnia komanda. Tyrimo objektas – komandos sutelktumo įvertinimas slaugytojų nuomone. Tyrimo tikslas – įvertinti komandos darbą teoriniu ir praktiniu lygmeniu bei atlikus duomenų analizę, palyginti slaugytojų, dirbančių chirurgijos ir terapijos profilio skyriuose, nuomonę apie komandos sutelktumą. Tyrimo uždaviniai: a) atskleisti komandinio darbo sampratą; b) nustatyti komandinio darbo formavimosi prielaidas ir principus; c) identifikuoti slaugytojų komandinio darbo sutelktumo ypatumus; d) palyginti gautus duomenis, įvertinant komandos sutelktumą tarp slaugytojų, dirbančių chirurgijos ir terapijos profilio skyriuose. Tyrimo metodai. Mokslinės literatūros analizė. Apklausa raštu. Duomenų analizė. Grafinis vaizdavimas. Išvados. Pagrindinis skirtumas tarp grupės ir komandos yra požiūris į sutelktumą ir iš to išplaukiančiais aspektais: tinkamas vadovavimas, bendravimas, pasitikėjimas ir veiklos efektyvumas. Sutelktos komandos formavimo refleksijos principas – bendrumas, kuris leidžia išnaudoti turimą žmogišką potencialą. Yra ryšys tarp komandos sutelktumo ir veiklos efektyvumo, kurie priklauso nuo komandoje susiformavusių normų. Slaugytojų komandos sutelktumui svarbu bendravimo įgūdžiai, probleminių situacijų sprendimai, bendri tikslai, veiksmų planas bei bendra veikla. Slaugytojų komandos sutelktumo pagrindas yra kiekvieno nario individualus savo ir komandos narių gebėjimų suvokimas. Tyrimo rezultatai atskleidė, kad slaugytojų komandų nariai dirba sutelktai ir darniai, pasitikėdami, padėdami, laiku informuodami vieni kitus, kontroliuodami ir dalyvaudami sprendimų priėmimuose. Tyrimo išvados atitinka mokslinėje literatūroje išvardintus sutelkto komandinio darbo kriterijus.

The Great Yeats Debate: Harriet Monroe, Ezra Pound, and Poetry Magazine's First Guarantor's Prize
Authors: O'Dea Dathalinn M.
Published: October 2015

This article addresses how W. B. Yeats and the Irish Revival were interpreted and reimagined for American audiences, particularly in the discursive statements of Harriet Monroe and Ezra Pound in Poetry magazine. Yeats's appearance in the magazine highlights a tension within Poetry between the publication's cosmopolitanism and its investment in regional writing. In keeping with a kind of revivalist logic that valued local cultural production, Poetry in fact demonstrated a provocative engagement with regional modernism. Examining the magazine's regionalism thus allows us to tease apart the complex and interesting ways that the Revival had an afterlife in this important modernist publication.

Endovascular implants currently used after cardiovascular events have proven their efficacy. However, strategies are in quest to optimize clinical outcomes. One possibility is the development of polymer surfaces imitating extracellular matrix in order to promote vascular integration of an implanted device. The aim of this study was to develop and investigate methods for covalent immobilization of a synthesized elastin-like protein (ELP) additionally modified with functional domains (RGD, CS5 and P15) promoting endothelial cell proliferation on biodegradable poly (L-lactide) (PLLA) as model endovascular implant surface. Evaluation of the impact of different ELP immobilization methods on PLLA regarding the achievable surface load evidences that the amino activation of PLLA does not have considerable influence, while the reaction sequence as well as the used crosslinker presents determining factors in ELP immobilization. Biocompatibility regarding selective promotion of endothelial cell (EC) adherence and proliferation especially in contrast to smooth muscle cells (SMC) was improved on covalently immobilized but not on physically adsorbed ELP. In summary, we could underline the applicability of a modified ELP-coating for endovascular implant surfaces in vitro and provide information on applicable immobilization procedures. Moreover, the latter builds the basis for a wide variety of implant applications, because the developed immobilization strategy should be easily transferable to any ELP with tailored biological functionality by exchange of the integrated active sequences.
Instructors’ Perceived Effectiveness of Current Professional Development Programs at Taif University English Language Center

Published: October 2015

The present paper aimed to explore the EFL instructors perceived effectiveness of current professional development programs run at Taif University English Language Center (TUELC) in Saudi Arabia, and to provide suggestions to improve the current situation of these programs. To achieve these purposes, the researcher tried to answer three questions. The first question investigated instructors’ perceptions of current professional development programs offered at the end of each semester, and the second and third questions examined the instructors’ possible reasons for agreement and disagreement with the items proposed in the questionnaire distributed to them, and the instructors’ suggestions to improve the current situation of professional development programs. A questionnaire of 4- Likert Scale and open-ended questions were used to gather data from seventy six teachers. The collected data were analyzed in the form of descriptive statistics, and content analysis was used for the open-ended questions. The results of the first question indicated that instructors in general have a negative attitude towards the current professional development programs run at the English Language Center. They only expressed their positive attitude towards the domains of professional knowledge and assessment strategies on the ground that they were given the opportunity to be interactive participants during discussing these two domains. Other possible reasons for agreement indicated that instructors shared knowledge and experience during the sessions of the program. However, their possible reasons for disagreement with the other domains showed that their actual needs were not considered when developing the program; they were mainly passive listeners, and the presenters were not professional enough to handle certain topics. Also, there was not enough focus on practice where learners could seek solutions to problems relevant to their classroom situations. They suggested that a needs assessment should be carried out and electronic professional development would be a good alternative to traditional meetings. Based on the results, the researcher drew certain conclusions and recommendations.

Legislation: challenges, dilemmas and innovation

Legislation as we know it is a recent phenomenon, and its quality has been under debate for 40 years. It is not surprising or problematic that the place and function of legislation evolve under the influence of societal changes. It is, however, important to change the mechanistic view of legislation. Instead of viewing it as an instrument of policy, we must search for structures and institutions that create room for diversity without breaking the unity of law. In our dealings with inevitable risks and damage to society, rules too often take the place of ethics or professional judgment. Rules are essential, but they should leave room to dissent from them if justified: rules as a point of departure, not rules that must be respected on pain of sanctions.
