A Sistematização da Assistência de Enfermagem (SAE) tem grande relevância no processo de trabalho da equipe de enfermagem, visando í excelência na qualidade de atenção í saúde do indiví­duo, da famí­lia e da comunidade. O estudo tem como objetivo conhecer a percepção do profissional de enfermagem sobre a SAE, em um hospital de Petrolina/PE. Trata-se de um estudo exploratório, descritivo e qualitativo, realizado com 14 profissionais de enfermagem de ní­vel técnico e superior. Os dados foram coletados no perí­odo de agosto a dezembro de 2017, por meio de entrevistas e analisados mediante técnica de análise de conteúdo de Bardin. As percepções dos profissionais de enfermagem resultaram nas categorias: SAE como ferramenta do planejamento dos cuidados de Enfermagem; desafios para implementação da SAE; e SAE proporcionando qualidade na assistência. Os profissionais de enfermagem reconhecem a importância da implementação da SAE e a identificam como condicionante fundamental para qualidade do cuidado, organização da equipe e fluidez da assistência global. O aspecto formativo surge como componente importante no caminho para a mudança, diante do predominante desconhecimento sobre a SAE, decorrente da provável escassez de abordagem sobre o tema na sua formação profissional, principalmente referente ao técnico de enfermagem.Palavras-chave: processo de enfermagem, percepção, planejamento em saúde, cuidados de enfermagem, protocolos.

Abstract
We present the results from a detailed analysis of our high-resolution spectra and historical photometric observations of the semidetached eclipsing binary V392 Ori with a δ Scuti (δ Sct) pulsating component. A total of 31 spectroscopic observations were carried out at both the Bohyunsan Optical Astronomy Observatory in Korea and the Thai National Observatory in Thailand during the 2016 and 2017 observing seasons. The radial velocities (RVs) of the primary and the faint secondary components were determined, and the effective temperature and projected rotational velocity of the former star were measured as T
eff,1 = 8500 ± 160 K and v
1 sin i = 148 ± 13 km s−1, respectively, through a comparison of the observed spectra and stellar atmosphere models. The physical properties of V392 Ori were determined by analysis of our RVs together with the existing multiband light curves. The results are the following: masses of M
1 = 2.28 ± 0.30 M
⊙ and M
2 = 0.49 ± 0.10 M
⊙, and radii of R
1 = 2.08 ± 0.09 R
⊙ and R
2 = 1.15 ± 0.05 R
⊙. The primary star located inside the main-sequence band exhibits a δ Sct-type pulsation. On the contrary, the less massive secondary component is significantly oversized and overluminous for its mass and temperature.
Automatic Detection and Tracking of Plumes from 67P/Churyumov–Gerasimenko in Rosetta/OSIRIS Image Sequences

Published: January 2019

Abstract
Solar system bodies such as comets and asteroids are known to eject material from their surface in the form of jets and plumes. Observations of these transient outbursts can offer insight into the inner workings and makeup of their originating body. However, the detection of and response to these events has thus far been manually controlled by ground operations, limiting the response time, due to the light time delay of ground communications. For distant bodies, the delay can exceed the duration of temporary events, making it impossible to respond with follow-up observations. To address this need, we developed a computer vision methodology for detecting plumes of the comet 67P/Churyumov–Gerasimenko from imagery acquired by the OSIRIS scientific camera system. While methods exist for the automatic detection of plumes on spherical and near-convex solar system bodies, this is the first work that addresses the case of highly irregularly shaped bodies such as 67P/Churyumov–Gerasimenko. Our work is divided into two distinct components: an image processing pipeline that refines a model-based estimate of the nucleus body, and an iterative plume detection algorithm that finds regions of local intensity maxima and joins plume segments across successively higher altitudes. Finally, we validate this method by comparing automatically labeled images to those labeled by hand, and find no significant differences in variability. This technique has utility in both ground-based analysis of plume sequences as well as onboard applications, such as isolating short sequences of high activity for priority downloading or triggering follow-up observations with additional instruments.
Radial Velocities in the Outermost Disk toward the Anticenter
Authors: López-Corredoira M. , Sylos Labini F. , Kalberla P. M. W. , Allende Prieto C. 
Published: January 2019

Abstract
We measure the mean Galactocentric radial component of the velocity of stars (v

R
) in the disk at 8 kpc < R < 28 kpc in the direction of the anticenter. For this, we use the Apache Point Galactic Evolution Experiment. Furthermore, we compare the result with H i maps along the same line of sight. We find an increase in positive (expansion) v

R
at R ≈ 9–13 kpc, reaching a maximum of ≈6 km s−1, and a decrease at large values of R, reaching a negative (contraction) value of ≈−10 km s−1 for R > 17 kpc. Negative velocities are also observed in 21 cm H i maps, possibly dominated by local gas emission. Among the possible dynamical causes for these non-zero v

R
, factors such as the effect of the Galactic bar, streams, or mergers do not seem appropriate to explain our observations. An explanation might be the gravitational attraction of overdensities in a spiral arm. As a matter of fact, we see a change of regime from positive to negative velocities around R ≈ 15 kpc, in the position where we cross the Outer spiral arm in the anticenter. The mass in spiral arms necessary to produce these velocities would be about 3% of the mass of the disk, consistent with our knowledge of the spiral arms. Another scenario that we explore is a simple class of out-of-equilibrium systems in which radial motions are generally created by the monolithic collapse of isolated self-gravitating overdensities.
The Properties of Parsec-scale Blazar Jets
Authors: Finke Justin D. 
Published: January 2019

Abstract
I show that, by assuming a standard Blandford–Königl jet, it is possible to determine the bulk Lorentz factor and angle to the line of sight of self-similar parsec-scale blazar jets by using five measured quantities: redshift, core radio flux, extended radio flux, the magnitude of the core shift between two frequencies, and apparent jet opening angle. From the bulk Lorentz factor and angle computed with this method, one can compute other jet properties such as the Doppler factor, magnetic field strength, and intrinsic jet opening angle. I use data taken from the literature and marginalize over nuisance parameters associated with the electron distribution and equipartition to compute these quantities, although the errors are large. Results are generally consistent with constraints from other methods. Primary sources of uncertainty are the errors on the core shift measurements and the uncertainty in the electron spectral index.
Bridging the Gap: Creating Faculty Development Opportunities at a Large Medical Center
Authors: James Kia M G 
Published: January 2019

ABSTRACT
Faculty development often focuses on developing practicing professionals into teaching experts within a classroom setting. As such, the topic of nursing faculty development is often written about from the standpoint of an employing traditional academic institution. Nursing faculty also have development needs related to practice within a clinical education institution. How do faculty members maintain a current perspective on endless changes in the clinical setting? This becomes particularly challenging if faculty are not actively engaged in nursing practice at the bedside and utilize a clinical facility for education sporadically throughout an academic year. This article describes the method one large academic medical center used to partner collaboratively with schools of nursing to create opportunities for faculty development. A need for clinical faculty development was recognized and a clinical facility faculty day was created and implemented. Information shared during this faculty development day included institutional practice changes, the implementation of a computerized medical record documentation system, general orientation policies, and procedures related to the conducting of business within the institution. A networking opportunity was also provided for faculty and the institutional healthcare leadership staff. Anecdotal evaluation information is also shared.
Fostering Ethical Competency: An Ongoing Staff Development Process That Encourages Professional Growth and Staff Satisfaction
Authors: Andrews Diane R 
Published: January 2019

ABSTRACTThe subject of ethics is integral to the modern practice of nursing. Research suggests that successful application of ethical decision-making skills is also integral to nurse satisfaction and, subsequently, nurse retention. The nurse manager is key to the development of those ethical decision-making skills. An increased appreciation of the process by which those skills are attained will assist the nurse manager in developing these skills in staff and thereby improve staff retention.
An Alternative Framework for Teacher Preparation in Nursing
Authors: Johnson-Crowley Nia 
Published: January 2019

ABSTRACT
Little nursing research has been done to explore the effectiveness of teacher preparation models. Nursing still uses traditional survey^type teacher preparation programs, yet educational research using these same models shows limited success in promoting students' teacher competence and confidence, limiting their desire to teach. However, current educational research reveals that courses designed around a constructivist model have had success in getting students to feel competent and confident to take on the teacher role and to incorporate new ideas of teaching into their teaching repertoire. The Experimental Teaching Course: Models of Teaching and Learning is designed to enhance graduate nursing students' competence and confidence as they identity and develop their own personal educator models for teaching and learning.
Disaster Preparedness: An Indictment for Action by Nursing Educators
Authors: Hilton Carla , Allison Vicky 
Published: January 2019

ABSTRACT
America is under constant threat of terrorist attack. The events of September 11, 2001, demonstrate the reality of the threat, as does the magnitude of the impact the attacks had on the healthcare systems of New York City and Washington, DC. Healthcare facilities and continuing education programs should incorporate training in nuclear, biological, and chemical disaster preparedness to provide the essential foundations for safe and effective health care. Advance training in disaster preparedness provides nurses with valuable training to fill the nationwide need for prepared first responders. American nurses have always responded selflessly to help in times of disaster and the country will be looking to nurses to respond to any future disasters.
The Prohibitive Costs of Accessing Evidence Online
Authors: Edwards Nancy , Lockett Donna 
Published: January 2019

ABSTRACT
Delivering continuing education online involves making published materials available to learners. As part of a study that examined the use of the Internet for dissemination of information, permission to provide resources online was sought from 43 publishers, of whom 36 responded. Four (11.1%) denied permission to copy their materials. Seven (19.4%) granted permission to copy articles at no cost. The remaining 25 (69.4%) granted permission for a fee, ranging from $2 to $410 per article. These findings highlight a need for more accessible and cost-effective online resources to meet the challenges of evidence-based programs and practice in public health.
Imagery: A Treatment for Nursing Student Anxiety
Authors: Stephens Rebecca L 
Published: January 2019

ABSTRACT
This study examined the effectiveness of audiotaped imagery in reducing anxiety and improving test performance among first-year nursing students. Volunteer subjects were randomly assigned to three groups, imagery-only, imagery/relaxation, and a no-treatment control group. Posttest state anxiety scores in these groups were significantly lower (p = .001) than in the no-treatment control group. Test performance did not differ significantly (p = .067). Subjects using the audiotaped imagery reported an increased sense of well-being, improved ability to sleep, greater energy, and improved self-confidence.
Absence of Keratectasia After LASIK in Eyes With Preoperative Central Corneal Thickness of 450 to 500 Microns
Authors: Caster Andrew I , Friess David W , Potvin Richard J 
Published: January 2019

ABSTRACT
PURPOSE: To determine whether preoperative central corneal thickness less than or equal to 500 µm is an independent risk factor for development of keratectasia following LASIK.
METHODS: Chart review was performed for 109 eyes with preoperative central corneal thickness of 452 to 500 µm in 69 patients who underwent LASIK between September 2000 and July 2005 and had no known risk factors for keratectasia. All eyes included in this analysis had postoperative manifest refractions at follow-up at 1-month and 12-months or greater (median: 452 days; range: 365 to 1980 days).
RESULTS: Attempted correction (spherical equivalent refraction) ranged from +3.13 to -7.75 diopters. There were no clinical signs of keratectasia at any postoperative visits in the 109 eyes in this study. There was no statistically significant change in mean spherical equivalent or manifest cylinder from the 1-month follow-up examination to the last documented visit (12 months or greater). No correlation was found for preoperative pachymetry and refractive change between postoperative examinations at 1 month and 12 months or greater. Double-angle vector analysis determined the directional shift in postoperative refractive cylinder was not statistically significant from zero (P>.05).
CONCLUSIONS: In this group of 109 LASIK-treated eyes with preoperative central corneal thickness less than or equal to 500 µm that were screened for known keratectasia risk factors, there was no evidence of postoperative keratectasia. [J Refract Surg. 2007;23:782-788.]
The Correlation of Pupil Size Measured by Colvard Pupillometer and Orbscan II
Authors: Hsieh Yi-Ting , Hu Fung-Rong 
Published: January 2019

ABSTRACT
PURPOSE: To assess the correlation of pupil sizes measured under different illuminations by Colvard pupillometer and the Orbscan II system and to determine the factors that may influence pupil sizes.
METHODS: The study comprised 162 eyes of 162 patients with a mean age of 34.6±10.6 years (range: 16 to 65 years). The photopic pupil sizes were measured with Orbscan II (363 lux). The high mesopic and low mesopic pupil sizes were measured by Colvard pupillometer under 60.5 and 0.15 lux of illumination, respectively. Spherical equivalent of the manifest refraction was used to evaluate its correlation with the pupil size.
RESULTS: The mean sizes of low mesopic and high mesopic pupil measured by Colvard pupillometer were 6.08±0.68 mm and 4.80±0.79 mm, respectively. The mean pupil size measured by Orbscan II was 3.87±0.61 mm. The pupil sizes were negatively correlated with age, but not correlated with refractive error when using multiple linear regression. Low mesopic pupil sizes were only moderately correlated with pupil sizes measured by Orbscan II (low mesopic pupil size [mm] = 0.755 × Orbscan II pupil size [mm] + 3.13, r = 0.67). If >4.5-mm pupil size measured by Orbscan II is used as the cut-off value for detecting low mesopic pupil sizes >6.5 mm, there will be a sensitivity of 48.15% and a specificity of 93.97%.
CONCLUSIONS: Pupil sizes measured with the Orbscan II were only moderately correlated with low mesopic pupil sizes measured with Colvard pupillometer. The Orbscan II is not a preferred tool for estimating low mesopic pupil sizes. [J Refract Surg. 2007;23:789-795.]
Shewanella putrefaciens Keratitis in the Lamellar Bed 6 Years After LASIK
Authors: Park Hee-Jung S , Tuli Sonal S , Downer Donald M , Gohari A Reza , Shah Milan 
Published: January 2019

ABSTRACT
PURPOSE: To present a case of infectious keratitis occurring 6 years after LASIK due to the rare human pathogen Shewanella putrefaciens.
METHODS: A 58-year-old man presented with redness and pain in the right eye 6 years following LASIK retreatment. Examination revealed a corneal infiltrate at the flap interface. Corneal scraping of stroma beneath the flap was submitted for histopathologic and microbiologic evaluation.
RESULTS: An infiltrate located at the LASIK flap interface originated from an epithelial defect at the flap-corneal junction. Corneal stroma cultures demonstrated Shewanella putrefaciens. The infection resolved with antibiotic treatment.
CONCLUSIONS: LASIK-related complications, such as infections, can occur many years following the procedure. The potential space created under the LASIK flap may predispose patients to infection by opportunistic organisms. [J Refract Surg. 2007;23:830-832.]

Published: January 2019

ABSTRACT
PURPOSE: To report two cases of infectious keratitis occurring after laser epithelial keratomileusis (LASEK).
METHODS: Two patients who underwent LASEK were referred to our center for the management of postoperative infectious keratitis. Infection occurred on postoperative days 2 (case 1) and 5 (case 2). Presenting visual acuity was count fingers in both cases.
RESULTS: Patients were treated aggressively with hourly topical broad-spectrum fortified antibiotics after corneal scrapings were obtained. Culture was positive for Staphylococcus aureus in case 2. Both eyes responded to treatment, resulting in residual corneal scarring with reduced best spectacle-corrected visual acuity of 20/40 in case 1 and uncorrected visual acuity of 20/25 in case 2.
CONCLUSIONS: Infectious keratitis can occur after LASEK surgery, and early diagnosis and aggressive therapy are required to reduce visual loss. [J Refract Surg. 2007;23:832-835.]
Randomized Prospective Comparison of Visian Toric Implantable Collamer Lens and Conventional Photorefractive Keratectomy for Moderate to High Myopic Astigmatism
Authors: Schallhorn Steven , Tanzer David , Sanders Donald R , Sanders Monica L 
Published: January 2019

ABSTRACT
PURPOSE: To compare the Visian Toric Implantable Collamer Lens (TICL), a toric phakic intraocular lens (IOL), and photorefractive keratectomy (PRK) in the correction of moderate to high myopic astigmatism.
METHODS: This prospective, randomized study consisted of 43 eyes implanted with the TICL (20 bilateral cases) and 45 eyes receiving PRK with mitomycin C (22 bilateral cases) with moderate to high myopia (-6.00 to -20.00 diopters [D] sphere) measured at the spectacle plane and 1.00 to 4.00 D of astigmatism. All patient treatment and follow-up occurred at the Naval Medical Center San Diego. Study follow-up was 1 day, 1 week, 1, 3, 6, and 12 months postoperative.
RESULTS: Mean best spectacle-corrected visual acuity (BSCVA), change in BSCVA, proportion of cases with improvement of 1 or more lines of BSCVA, proportion of cases with BSCVA and uncorrected visual acuity (UCVA) 20/12.5 or better, proportion of cases with BSCVA and UCVA 20/16 or better (6 months, 88% vs 54%, P=. 002), and predictability ?1.00 D (6 months, 100% vs 67%, P<.001) were all significantly better in the TICL group than the PRK group at all time periods studied postoperatively. Similarly, contrast sensitivity, tested at both the 5% photopic level and the 25% mesopic level, was significantly better at all postoperative time points in the TICL group. Mean spherical equivalent refraction was closer to emmetropia (0.28?0.41 vs 0.76?0.86, P=. 005), and predictability ?0.50 D and stability of manifest refraction (?0.50 D and ?1.00 D) were significantly better in the TICL group at all postoperative visits through 6 months. Mean astigmatism correction at 6 months was not significantly different between the two groups (0.52?0.33 vs 0.46?0.35, P=.450).
CONCLUSIONS: The TICL performed better than PRK in all measures of safety (BSCVA), efficacy (UCVA), predictability, and stability in this comparison, supporting the TICL as a viable alternative to existing refractive surgical treatments. [J Refract Surg. 2007;23:853-867.]
