Authors: Aminzadeh Faranak , Byszewski Anna , Dalziel William Burd , Wilson M , Deane N , Papahariss-Wright S
Published: May 2014

ABSTRACT

In this study, the authors examined the goals and outcomes of 141 caregivers of older adults with cognitive impairment who attended a comprehensive geriatric assessment program (CGA). The vast majority of caregivers expressed at least one assessment goal, suggesting that the concept was relevant to them. Most caregiver goals focused on patient needs, with only 10% expressing goals specifically related to their own coping needs. At follow up, more than two-thirds of caregiver goals were attained. The findings confirm the great potential of CGA programs in promoting positive outcomes and point to the opportunities for nurses to improve the process of care.

Effects on Agitated Patients with Dementia

ABSTRACT

Agitation in individuals with severe cognitive impairment is a significant problem that affects care and overall quality of life. Building on research conducted by Goddaer and Abraham (1994), this quasi-experimental study proposed that relaxing music played during meals would exert a calming effect and decrease agitated behaviors among nursing home residents with dementia. Thirty residents residing in a Special Care Unit participated in the 4-week study. The Cohen-Mansfield Agitation Inventory (Cohen-Mansfield, Marx, & Rosenthal, 1989) was used to gather data. Baseline data was obtained in Week 1 (no music). Music was introduced in Week 2, removed in Week 3, and reintroduced in Week 4. At the end of the 4-week study, overall reductions in the cumulative incidence of total agitated behaviors were observed. Reductions in absolute numbers of agitated behaviors were achieved during the weeks with music and a distinct pattern was observed.
A TYPOLOGY OF ORAL HYDRATION: PROBLEMS EXHIBITED BY FRAIL NURSING HOME RESIDENTS
Authors: Mentes Janet C
Published: May 2014

ABSTRACT

Dehydration remains a substantial problem for nursing home residents, often with poor health outcomes. The purpose of this investigation was to establish 6-month prevalence of dehydration events in nursing home residents and to describe common hydration problems of nursing home residents. In this prospective observational study, 35 nursing home residents were followed for 6 months to assess problems with hydration and to evaluate the presence of dehydration. Urine specific gravity and color, bioimpedance measurements, meal intake recordings, and chart abstraction were used to assess hydration status. Field notes and informal staff interviews were used to describe specific hydration problems and clinically relevant interventions. Dehydration events occurred in 31% (11 of 35) of residents during the 6-month period. A typology of hydration problems was developed from the field observations. The typology consists of four groups (i.e., Can Drink, Can't Drink, Won't Drink, End of Life) and six corresponding subgroups. Demographic and hydration characteristics of the subgroups were compared and contrasted. Comparisons revealed the Won't Drink group is most vulnerable to dehydration events because this group has the highest percentage of dehydration events (58%, 4 of 7), the highest average specific gravity, and the lowest consumption of fluids during meals. Nursing interventions for the subgroups are discussed. Targeting nursing interventions to the specific hydration problem exhibited is proposed.

The purpose of this article is twofold: to emphasize the need for nutritional assessment across the continuum of care as experienced by older adults, and to identify possible barriers to effective treatment. The assessment of nutritional status and the implementation of effective nutritional interventions are essential to the health of older adults.
Overcoming Restraint Use: EXAMINING BARRIERS IN AUSTRALIAN AGED CARE FACILITIES
Authors: Nay Rhonda , Koch Susan
Published: May 2014

ABSTRACT

The purpose of this article is to discuss the outcomes of a project that sought to identify alternatives to restraint use in aged care facilities. (In Australia, the term aged care facility refers to those facilities previously known as hostels and nursing homes.) A literature review was conducted and discussion forums and individual interviews were held with interested stakeholders in Australian capital cities, as well as in a rural city in each state. Site visits were conducted at 16 aged care facilities. Participants identified legal concerns, existing organizational culture, and lack of alternatives as barriers to implementing restraint-minimization practices. Recommendations to facilitate minimal restraint are implementing national policy guidelines, adopting a best practice philosophy in relation to restraint minimization, continuing staff education related to alternatives, and maintaining constant communication with families.
Conflict Resolution Styles: A Comparison of Assisted Living and Nursing Home Facilities
Authors: Small Jeff A , Montoro-Rodriguez Julian
Published: May 2014

ABSTRACT

In this exploratory study, the authors investigated how interpersonal conflict is resolved in assisted living and nursing home facilities. In particular, the authors examined whether conflict resolution styles differed between type of facility and between residents and staff in each type of facility. Four focus groups were conducted - two with residents and two with staff from each type of facility. The focus groups centered on discussing the occurrence of conflict and how each participant handled it. Discourse analysis was employed to identify participants' use of three styles of conflict resolution: controlling, solution-oriented, and non-confrontational. The results indicate that staff in each care context showed a preference for the solution-oriented approach. Residents in each setting reported equal use of the non -confrontational and solution-oriented styles. The findings suggest that preferred conflict resolution styles may vary more as a function of the role of each communicator than the context of the care setting.

Older Adults' Views of Cardiac Rehabilitation Programs: Is it Time to Reinvent?
Authors: Dolansky Mary A , Moore Shirley M , Visovsky Constance
Published: May 2014

ABSTRACT

In spite of the documented benefits of cardiac rehabilitation program (CRP) participation, older adults are not likely to participate. Older adults' expectations of and experiences with CRPs are not known. It is also not known whether women and men differ in their expectations and experiences. This descriptive study used a convenience sample of 40 older adults who had experienced an acute cardiac event to identify patients' views of CRPs. Focus groups revealed that older adults do not have an accurate understanding of what to expect in CRPs, and that older adults' experiences in CRPs were generally positive. Older adults suggested CRPs could be improved by including more socialization opportunities, offering varied forms of exercise, enhancing teaching about stress management, and adapting teaching strategies. In this study, "strength of physician referral" was identified as the main reason for participating or not participating in a CRP. Older men feared physical pain with exercise and older women expressed a need for emotional support. A major finding in this study was the report of adverse events (i.e., exhaustion, collapse) during exercise experienced by individuals who did not go to a CRP. Because the majority of adults participating in CRPs are older, transforming CRPs to meet the needs of these older adults is important. Future research on the effectiveness of alternative CRP models will provide evidence to ensure the delivery of quality, cost-effective care.
A alusão a romances nas letras portuguesas dos séculos XV-XVII
Authors: Araújo Teresa
Published: May 2014

Las preocupaciones de Ochocientos con respecto al establecimiento de la idea de literatura llevaron al (re)descubrimiento de versos de romances peninsulares en varias obras de autores portugueses contemporáneos de Garcia de Resende, Luís de Camões y D. Francisco Manuel de Melo (incluyendo ellos mismos). Superadas la perspectiva romanticista y la de la filología de la época, así como revisadas las teorías de la intertextualidad de finales del siglo XX, el estudio incide sobre estas interpolaciones en las letras portuguesas. Las interpreta como dispositivos de alusión con efectos musicales, poéticos y semánticos tan diversos cuanto precisos e imprescindibles desde el punto de vista de la economía creativa de las obras que las presentan. A través de la combinatoria identificación de los romances aludidos / interpretación del sentido y función de las incrustaciones deslinda significados textuales que no son perceptibles mediante una lectura meramente lineal.
La expulsión de los jesuitas de Portugal en la “era pombalina”
Authors: Vivanco Díaz Borja
Published: May 2014

Los jesuitas fueron expulsados de Portugal en 1759 como consecuencia de la política “regalista” del “despotismo ilustrado” y a la que se había adherido sin reservas el Marqués de Pombal, primer ministro del rey José I. Las acusaciones de instigar a los guaraníes a rebelarse contra el Tratado de los Límites, por un lado, y de conspirar en la organización del atentado frustrado contra la vida de José I, por otro, sirvieron de argumentos para provocar el exilio de la Compañía de Jesús. Sin embargo, ninguna de las dos acusaciones ha podido ser nunca probada y respondieron más bien a la campaña “pombalina” contra la orden de Ignacio de Loyola. Como resultado final, la expulsión de los jesuitas aminoró la influencia de la Iglesia Católica y favoreció la introducción en Portugal de las nuevas ideas de la Ilustración.
“Mensaje del verdadero Portugal”. Los intelectuales portugueses, la IIª República española y el fascismo ibérico: prensa y propaganda
Authors: Pena Rodríguez Alberto
Published: May 2014

Este estudio pretende ahondar en algunos aspectos inéditos sobre el papel político jugado por los intelectuales portugueses en los inicios de la dictadura salazarista y su relación con España, especialmente en el marco de la Guerra Civil española. El Estado Novo de António de Oliveira Salazar contó con la colaboración de prestigiosos intelectuales, que aceptaron los nuevos presupuestos ideológicos del salazarismo y contribuyeron a su legitimación pública. Muchos intelectuales lusos se convirtieron, además, en propagandistas del movimiento franquista. Un caso paradigmático de su activismo a favor del fascismo ibérico, en el que se basa esta investigación, fue la campaña internacional que algunos de ellos realizaron a favor de la nueva España franquista. Esto provocó la respuesta de los intelectuales portugueses exiliados en España, que hicieron público el 4 de octubre de 1936 un manifiesto anti-fascista titulado “Mensaje del verdadero Portugal”.
Globalización y desnacionalización en la novela portuguesa actual
Authors: Fernández García M.ª Jesús
Published: May 2014

La literatura portuguesa ha estado a lo largo de su historia especialmente atenta a la construcción de la imagen identitaria de Portugal. Esta preocupación, visible en todos los planos de la vida social, no solo en la producción de los discursos culturales, se ve confrontada al menos desde las dos últimas décadas con el empuje del proceso globalizador, fuerza homogeneizadora que transforma el perfil de las sociedades contemporáneas. El discurso literario acompaña este proceso, lo alimenta y forma parte de él, como tratamos de ver a partir de algunas novelas de reciente publicación en Portugal, abiertas a la simbolización de nuevos paisajes y conflictos que se alejan de la representación en exclusividad del espacio portugués y del debate identitario nacional.
Bombardeando patrimonio en el Campo de Tiro Militar de El Teleno (León): de la sublimación de la naturaleza a la construcción social del patrimonio cultural
Authors: Alonso González Pablo , Macías Vázquez Alfredo
Published: May 2014

Se analiza la construcción social del Campo de Tiro Militar de El Teleno como reserva natural a partir de la retórica auspiciada por el “giro ambientalista” del Ministerio de Defensa. Ante la conflictividad existente en Maragatería, esta estrategia de contención deviene en una sublimación ideológica: la posibilidad de la preservación (natural) viene dada por la reproducción necesaria de la destrucción (humana). Por su parte, las estrategias de resistencia han adoptado formas diferentes. Entre ellas, la construcción social del Teleno como patrimonio cultural socava la estrategia de sublimación del C.M.T. como “paraíso natural”, mostrando la fuerte presencia humana previa en la zona. Ambas metanarrativas se han convertido en el pilar fundamental alrededor del cual se organizan las luchas simbólicas entre instituciones y activistas, lo que representa un cambio fundamental al dejar fuera a las personas y las relaciones inmanentes de las comunidades con el bosque. En ambos discursos metaculturales, se reproduce la separación entre naturaleza y cultura tan característica de la modernidad.

In order to study the treatment of simulated radioactive graphite contains 90Sr by SHS and its β-irradiation stability, waste forms were prepared in accordance with the reaction 3C + 4Al + 3TiO2 = 2Al2O3 + 3TiC+Q, by self-designed SHS equipment. Then the β-ray irradiation experiments were done at dose of 106Gy to evaluate its radiation resistance. The phase composition and morphology of the prepared waste forms before and after irradiation were characterized by X-ray diffractometer (XRD) and scanning electron microscope (SEM). The XRD results indicated that the major composition of the waste forms were Al2O3, TiC, C, TiO2 and AlN after reaction in atmosphere, and the SrO solid solubility could be up to 8wt%. It was found that the surface morphology of waste forms were mostly plate-shaped and mainly in about 10μm. The structure and microscopic morphology of waste forms didn't change significantly before and after irradiation according to the XRD spectra, SEM photos. Moreover, the calculated cell parameters results suggested that the lattice parameters of the main phase (TiC, Al2O3) changed about 10-3~10-2nm after irradiation, and the degree of changes in cell volume was about 10-4~10-3nm3 magnitude. The simulated 90SrO–containing radioactive graphite waste forms showed a certain β-ray radiation resistance.

Authors: Tsai Ming June , Wu Ching Tsai
Published: May 2014

This study aimed to confirm the application of multi-implants for mandibles with a large edentulous area using methods of finite element analysis (FEA). 3D finite element models of mandible with multi-implants were generated form reverse engineering of CT images stored in DICOM format. In the FEA of the implant model, the majority of the stress falls onto neck of the titanium implant and is well-distributed around the cylinder body of screw, resulting in less stress being applied to the cortical bone around titanium screw. Under a continual normal force of 100 N, The maximum stress on the cortical bone was located in the area around the titanium implants, and was 111.62Mpa, while the maximum stress on the titanium implant was located at the neck of the implant, and was 120.35 Mpa, much lower than the yield strength of the titanium framework (1260Mpa). The maximum deformation was around 0.65 mm. The deformation of the alveolar bone in our multi-implant model was within the acceptable range. This study show that the titanium screw used for multi-implants meets the requirements in term of physical properties for a large area of defects.

Published: May 2014

In this investigation, grain orientation has been studied in an industrial aluminium Al99.5 which has been welded by TIG process. The optical microscopy and EBSD (Electron Back Scattered Diffraction) were the main techniques used to illustrate the effect of welding on grain orientation in fusion zone and in heat affected zone. Epitaxial growth has been observed in weld joint and texture of each zone has been determined. On the other hand, the effect of isothermal heat treatment at 400 °C on homogenization of welded joint has been also studied. It was shown that the cube orientation {001}<100> is the dominant texture component in welded joint before or after heat treatments.

Authors: Gao Li , Zhi Er Juan , Wang Ping Li , Ji Jun Hui
Published: May 2014

In this study, poly (butylene succinate) (PBS)/nature rubber (NR) composites were prepared, and the effects of NR content on the biodegradability were evaluated by vermiculite-degradation test. X-ray Diffraction, differential scanning calorimetry (DSC), and scanning electron microscopy (SEM) were used to characterize the degraded blends. The weight losses of PBS/NR composites are higher than that of pure PBS, and increased with adding NR content. The weight loss of 30% NR content composite after 120 days is 16.84%. The XRD and DSC results show that the crystallinity of PBS/NR composites increase after buried in vermiculite. These results were confirmed using SEM observations by the presence of many large holes and more cracks in the degradation surface morphology of the increasing content of NR. It was observed that PBS/NR composites are green-composites or eco-materials.

Some significant differences about nucleosome positioning of different expression patterns gene have been found while researching the nucleosome positioning of Drosophila embryogenesis. The difference from the previous study was the restricted expression pattern gene incorporating H2A.Z into the-1 nucleosome in the upstream of Transcription Start Sites (TSS). Interestingly, compared with the nucleosome positioning of yeast genes, this nucleosome arrangement at gene of restricted expression pattern is similar with the characteristic found in yeast.

In the 19th century, Julius Wolff put forward the law of bone transformation, it has been widely known that the trabecular structure of cancellous bone depend on the mechanical characteristic of cancellous bone. At present, in the field of bone remodeling and biomechanics, FE method and computer simulation are playing important role in simulating and predicting the bone mineral density or bone structure. To establish a quantized biological model of bone growth and remodeling adaptation, which integrates animal experiments, unknown parameter inversion identification of mathematical functions and technique of computer simulation. The 80 rats were randomly divided into three groups: 15 rats were in normal control groups, 45 in experiment groups, 20 in validation and prediction groups. By designing a new animal experiment, we investigate the effects of stress environments on bone growth and remodeling of rapid growing rats. And gather the bone mineral density (BMD) of proximal femur in the same interval for the unknown parameters (B and K) inversion of bone growth. The model of bone growth and remodeling advanced in this paper can not only numerically simulate the relationship between outer stimulus and the femur BMD variation of rapid growing rats, but also predict the growth trend of rat femur under different stress environments in its whole lifecycle.In this paper, we showed that the modeling ideas and methods for human bone reconstruction tips to provide clue and reference to establishing human model of bone growth and remodeling.

Authors: Wen Chan Chao , Kuo Wen Shyong
Published: May 2014

This work examines the processing and some mechanical properties of copper-electroplated graphite compacts. Shear and wear tests were conducted. Natural graphite (NG) flakes were compressed to make graphite compacts. No polymer binder was added in the compact. For reinforcing and preventing the NG particles from peeling off, a copper layer was electroplated on the compact. The density of green graphite compact approached a limit when the forming pressure was higher than 100 MPa. The results indicated that the shear strengths increase 150% and the wear resistance is improved more than ten times because of the copper layer. The induced damage mechanisms were examined, and the influence of the copper layer on the damage is discussed.
