Measuring KMS success: A respecification of the DeLone and McLean's model

We proposed and empirically assessed a KMS success model. This was derived through an analysis of current practice of knowledge management and review of IS success literature. Five variables (system quality, knowledge or information quality, perceived KMS benefits, user satisfaction, and system use) were used as dependent variables in evaluating KMS success, and their interrelationships were suggested and empirically tested. The results provide an expanded understanding of the factors that measure KMS success and implications of this work are discussed. # 2006 Elsevier B.V. All rights reserved.
Effects of drought on child health in Marsabit District, Northern Kenya.

This study uses five years of panel data (2009-2013) for Northern Kenya's Marsabit district to analyze the levels and extent of malnutrition among children aged five and under in that area. We measure drought based on the standardized normalized difference vegetation index (NDVI) and assess its effect on child health using mid-upper arm circumference (MUAC). The results show that approximately 20 percent of the children in the study area are malnourished and a one standard deviation increase in NDVI z-score decreases the probability of child malnourishment by 12-16 percent. These findings suggest that remote sensing data can be usefully applied to develop and evaluate new interventions to reduce drought effects on child malnutrition, including better coping strategies and improved targeting of food aid.

Exploiting Perceptual Illusions to Enhance Passive Haptics

Passive haptic feedback is very compelling, but a different physical object is needed for each virtual object requiring haptic feedback. I propose to enhance passive haptics by exploiting visual dominance, enabling a single physical object to provide haptic feedback for many differently shaped virtual objects. Potential applications include virtual prototyping, redirected walking, entertainment, art, and training.
Assessment of QRS duration and presence of fragmented QRS in patients with Behçet's disease.

BACKGROUND
QRS prolongation and the presence of QRS fragmentation in 12-lead ECG are associated with increased mortality and sudden cardiac death in the long term. In this study we aimed to assess QRS duration and fragmentation in patients with Behçet's disease (BD).


METHODS
A total of 50 patients (mean age 42.7±12.0 years) previously diagnosed with BD were recruited. In addition, a control group consisting of 50 healthy people (mean age 39.4±12.5 years) was formed. The longest QRS duration was measured in surface 12-lead ECG and QRS complexes were evaluated in terms of fragmentation. Serum C-reactive protein levels were also obtained.


RESULTS
QRS duration and corrected QT duration were significantly longer in patients with BD compared with controls (102.75±11.91 vs. 96.99±10.91 ms, P=0.007; 438.55±30.80 vs. 420.23±28.06 ms, P=0.003, respectively). Fragmented QRS (fQRS) pattern was more common in patients with BD than controls [n=27 (54%) vs. n=16 (32%), P=0.026]. Disease duration was longer in patients with BD with fQRS compared with those without (12.67±8.68 vs. 7.09±7.06 years, P=0.010). Furthermore, C-reactive protein level was higher in patients with BD with fQRS compared with those without (6.53±4.11 vs. 4.97±6.32 mg/dl, P=0.043). Correlation analysis revealed no association between disease duration and QRS duration (r=0.219, P=0.126).


CONCLUSION
QRS duration is greater and fQRS complexes are more frequent in patients with BD. These findings may indicate subclinical cardiac involvement in BD. Given the prognostic significance of ECG parameters, it is reasonable to evaluate patients with BD with prolonged and fQRS complexes more in detail such as late potentials in signal averaged ECG in terms of cardiac involvement.
Polynomial Algorithms in Computer Algebra

Chinese remainder problem Given: rl, ... , rn E R (remainders) 11, ... , In ideals in R (moduli), such that Ii + Ij = R for all i =f. j Find: r E R, such that r == ri mod Ii for 1 ::: i ::: n The abstract Chinese remainder problem can be treated basically in the same way as the CRP over Euclidean domains. Again there is a Lagrangian and a Newtonian approach and one can show that the problem always has a solution and if r is a solution then the set of all solutions is given by r + II n ... n In. 3.1 Chinese remainder problem 57 That is, the map ¢J: r t-+ (r + h, ... , r + In) is a homomorphism from R onto nj=1 R/lj with kernel II n ... n In. However, in the absence of the Euclidean algorithm it is not possible to compute a solution of the abstract CRP. See Lauer (1983). A preconditioned Chinese remainder algorithm If the CRA is applied in a setting where many conversions w.r.t. a fixed set of moduli have to be computed, it is reasonable to precompute all partial results depending on the moduli alone. This idea leads to a preconditioned CRA, as described in Aho et al. (1974). Theorem 3.1.7. Let rl, ... , rn and ml, ... , mn be the remainders and moduli, respectively, of a CRP in the Euclidean domain D. Let m be the product of all the moduli. Let Ci = m/mi and di = ci l mod mi for 1 :::s i :::s n. Then n r = LCidiri mod m i=1 is a solution to the corresponding CRP. (3.l.1) Proof Since Ci is divisible by mj for j =1= i, we have Cidiri == 0 mod mj for j =1= i. Therefore n LCidiri == cjdjrj == rj mod mj, for all l:::s j :::s n . 0 i=1 A more detailed analysis of (3.l.1) reveals many common factors of the expressions Cidiri. Let us assume that n is a power of 2, n = 2t. Obviously, ml ..... mn/2 is a factor of Cidiri for all i > n/2 and m n/2+1 ..... mn is a factor of Cidiri for all i :::s n/2. So we could write (3.1.1) as

A New Approch For Ridge Preservation : Socket Shield Technique : A Review *

Tooth loss and subsequent ridge collapse continue to burden restorative implant treament. Careful management of the post-extraction tissues is needed to preserve the alveolar ridge. In-lieu of surgical augmentation to correct a ridge defect, the socket-shield technique offers a promising solution. As the root submergence technique retains the periodontal attachment and maintains the alveolar ridge for pontic site development, this review article demonstrates the hypothesis that retention of a prepared tooth root section as a socket-shield prevents the recession of tissues buccofacial to an immediately placed implant. keywords: Alveolar bone preservation, buccal bone, esthetic zone, extraction socket, immediate implant, socket shield --------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 0X -XX-2017 Date of acceptance: 18-10-2017 ---------------------------------------------------------------------------------------------------------------
Predictors of long-term outcomes in patients with significant myxomatous mitral regurgitation undergoing exercise echocardiography.

BACKGROUND
Significant myxomatous mitral regurgitation leads to progressive left ventricular (LV) decline, resulting in congestive heart failure and death. Such patients benefit from mitral valve surgery. Exercise echocardiography aids in risk stratification and helps decide surgical timing. We sought to assess predictors of outcomes in such patients undergoing exercise echocardiography.


METHODS AND RESULTS
This is an observational study of 884 consecutive patients (age, 58 ± 14 years; 67% men) with grade III+ or greater myxomatous mitral regurgitation who underwent exercise echocardiography between January 2000 and December 2011 (excluding functional mitral regurgitation, prior valvular surgery, hypertrophic cardiomyopathy, rheumatic valvular disease, or greater than mild mitral stenosis). Clinical and echocardiographic data (mitral regurgitation, LV ejection fraction, LV dimensions, right ventricular systolic pressure) and exercise variables (metabolic equivalents, heart rate recovery at 1 minute after exercise) were recorded. Composite events of death, myocardial infarction, stroke, and progression to congestive heart failure were recorded. Mean LV ejection fraction, indexed LV end-systolic dimension, resting right ventricular systolic pressure, peak stress right ventricular systolic pressure, metabolic equivalents achieved, and heart rate recovery were 58 ± 5%, 1.6 ± 0.4 mm/m(2), 31 ± 12 mm Hg, 46 ± 17 mm Hg, 9.6 ± 3, and 33 ± 14 beats, respectively. During 6.4 ± 4 years of follow-up, there were 87 events. On stepwise multivariable Cox analysis, percent of age/sex-predicted metabolic equivalents (hazard ratio, 0.99; 95% confidence interval, 0.98-0.99; P=0.005), heart rate recovery (hazard ratio, 0.29; 95% confidence interval, 0.17-0.50; P<0.001), resting right ventricular systolic pressure (hazard ratio, 1.03; 95% confidence interval, 1.004-1.05; P=0.02), atrial fibrillation (hazard ratio, 1.91; 95% confidence interval, 1.07-3.41; P=0.03), and LV ejection fraction (hazard ratio, 0.96; 95% confidence interval, 0.92-0.99; P=0.04) predicted outcomes.


CONCLUSIONS
In patients with grade III+ or greater myxomatous mitral regurgitation undergoing exercise echocardiography, lower percent of age/sex-predicted metabolic equivalents, lower heart rate recovery, atrial fibrillation, lower LV ejection fraction, and high resting right ventricular systolic pressure predicted worse outcomes.
Population‐based analysis of pathological correlates of dementia in the oldest old

OBJECTIVE
The aim of this study was to analyze brain pathologies which cause dementia in the oldest old population.


METHODS
All 601 persons aged ≥85 years living in the city of Vantaa (Finland), on April 1st, 1991 formed the study population of the Vantaa85 +  study, 300 of whom were autopsied during follow-up (79.5% females, mean age-at-death 92 ± 3.7 years). Alzheimer's disease (AD) pathology (tau and beta-amyloid [Aβ]), cerebral amyloid angiopathy (CAA) and Lewy-related pathologies were analyzed. Brain infarcts were categorized by size (<2 mm, 2-15 mm, >15 mm) and by location. Brain hemorrhages were classified as microscopic (<2 mm) and macroscopic.


RESULTS
195/300 (65%) were demented. 194/195 (99%) of the demented had at least one neuropathology. Three independent contributors to dementia were identified: AD-type tau-pathology (Braak stage V-VI), neocortical Lewy-related pathology, and cortical anterior 2-15 mm infarcts. These were found in 34%, 21%, and 21% of the demented, respectively, with the multivariate odds ratios (OR) for dementia 5.5, 4.5, and 3.4. Factor analysis investigating the relationships between different pathologies identified three separate factors: (1) AD-spectrum, which included neurofibrillary tau, Aβ plaque, and neocortical Lewy-related pathologies and CAA (2) >2 mm cortical and subcortical infarcts, and (3) <2 mm cortical microinfarcts and microhemorrhages. Multipathology was common and increased the risk of dementia significantly.


INTERPRETATION
These results indicate that AD-type neurodegenerative processes play the most prominent role in twilight cognitive decline. The high prevalence of both neurodegenerative and vascular pathologies indicates that multiple preventive and therapeutic approaches are needed to protect the brains of the oldest old.
Closure of defects of the malar region.

BACKGROUND
Reconstruction of the skin defects of malar region poses some challenging problems including obvious scar formation, dog-ear formation, trapdoor deformity and displacement of surrounding anatomic landmarks such as the lower eyelid, oral commissure, ala nasi, and sideburn.


PURPOSE
Here, a new local flap procedure, namely the reading man procedure, for reconstruction of large malar skin defects is described.


MATERIALS AND METHODS
In this technique, 2 flaps designed in an unequal Z-plasty manner are used. The first flap is transposed to the defect area, whereas the second flap is used for closure of the first flap's donor site. In the last 5 years, this technique has been used for closure of the large malar defects in 18 patients (11 men and 7 women) aged 21 to 95 years. The defect size was ranging between 3 and 8.5 cm in diameter.


RESULTS
A tension-free defect closure was obtained in all patients. There was no patient with dog-ear formation, ectropion, or distortion of the surrounding anatomic structures. No tumor recurrence was observed. A mean follow-up of 26 months (range, 5 mo to 3.5 y) revealed a cosmetically acceptable scar formation in all patients.


CONCLUSIONS
The reading man procedure was found to be a useful and easygoing technique for the closure of malar defects, which allows defect closure without any additional excision of surrounding healthy tissue. It provides a tension-free closure of considerably large malar defects without creating distortions of the mobile anatomic structures.

Low-cost foods: how do they compare with their brand name equivalents? A French study.

OBJECTIVE
Consumers are increasingly relying on low-cost foods, although it is not clear if the nutritional quality of these foods is fully maintained. The aim of the present work was to analyse the relationship between cost and quality within a given food category.


DESIGN AND SETTING
The relationship was analysed between nutritional quality and cost for 220 food products belonging to seventeen different categories, controlling for package type and package size. Given that a summary of nutrient information was not available on the product label, a novel ingredient quality score was developed based on listed product ingredients.


RESULTS
Within a given category, the lowest-priced foods were not different from the equivalent branded products in terms of overall energy or total fat content. Nevertheless, a positive relationship, small but significant, was observed between the price and the ingredient quality score. On average, the branded products cost 2.5 times more than the low-cost products, for an equivalent energy and lipid content, and had a slightly higher (1.3 times) ingredient quality score.


CONCLUSIONS
More studies are necessary to evaluate the nutritional quality of low-cost foods. This evaluation would be facilitated if nutrition labelling was mandatory. Yet in view of the present results, it does not seem to be justified to divert consumers, especially the poorest, from low-cost foods because this may have an adverse effect on the nutritional quality of their diet, by reducing further the fraction of their food budget spent on fresh fruit and vegetables.
Topological structural analysis of digitized binary images by border following

Two border following algorithms are proposed for the topological analysis of digitized binary images. The first one determines the surroundness relations among the borders of a binary image. Since the outer borders and the hole borders have a one-to-one correspondence to the connected components of l-pixels and to the holes, respectively, the proposed algorithm yields a representation of a binary image, from which one can extract some sort of features without reconstructing the image. The second algorithm, which is a modified version of the first, follows only the outermost borders (i.e., the outer borders which are not surrounded by holes). These algorithms can be effectively used in component counting, shrinking, and topological structural analysis of binary images, when a sequential digital computer is used. o 1985 Academic press, I~C.
Chapter Fifteen. Homer’S Phoenicians: History, Ethnography, Or Literary Trope? [A Perspective On Early Orientalism]

This chapter explores the texts of Iliad and the Odyssey and examines how to account for anomalies between the historical evidence and the way Phoenicians are represented. It considers two aspects of how to account for the picture(s) drawn: first, a double-pronged inquiry into the role the Phoenicians can be seen to play within the texts, along with an analysis of the narrative goals of those portions of the text in which Phoenicians appear, that would account for the way they were represented; and second, a consideration of the role the Homeric texts themselves may be said to have played within the larger context of eighth/seventh-century Greece, the presumed time of their writing. ?Homer's Phoenicians," present a masterful literary construct, at once produced by and working to produce the broader social, political, economic, and symbolic fabric of the early state in Archaic Greece.Keywords: Archaic Greece; early orientalism; Homer's Phoenicians; Iliad; Odyssey
Multiple Light Source Estimation in a Single Image

Many high-level image processing tasks require an estimate of the positions, directions and relative intensities of the light sources that illuminated the depicted scene. In image-based rendering, augmented reality and computer vision, such tasks include matching image contents based on illumination, inserting rendered synthetic objects into a natural image, intrinsic images, shape from shading and image relighting. Yet, accurate and robust illumination estimation, particularly from a single image, is a highly ill-posed problem. In this paper, we present a new method to estimate the illumination in a single image as a combination of achromatic lights with their 3D directions and relative intensities. In contrast to previous methods, we base our azimuth angle estimation on curve fitting and recursive refinement of the number of light sources. Similarly, we present a novel surface normal approximation using an osculating arc for the estimation of zenith angles. By means of a new data set of ground-truth data and images, we demonstrate that our approach produces more robust and accurate results, and show its versatility through novel applications such as image compositing and analysis.
Robotic surgery: changing the surgical approach for endometrial cancer in a referral cancer center.

STUDY OBJECTIVE
To study the effect of robotic surgery on the surgical approach to endometrial cancer in a gynecologic oncology center over a short time.


DESIGN
Prospective analysis of patients with early-stage endometrial cancer who underwent robotic surgery.


SETTING
Teaching hospital.


PATIENTS
Eighty patients who underwent robotic surgery.


INTERVENTIONS
Between November 2006 and October 2008, 80 consecutive patients with an initial diagnosis of endometrial cancer consented to undergo robotic surgery at the European Institute of Oncology, Milan, Italy.


MEASUREMENTS AND MAIN RESULTS
We collected all patient data for demographics, operating time, estimated blood loss, histologic findings, lymph node count, analgesic-free postoperative day, length of stay, and intraoperative and early postoperative complications. Mean (SD) patient age was 58.3 (11.5) years (95% confidence interval [CI], 55.7-60.9). Body mass index was 25.2 (6.1) kg/m(2) (95% CI, 23.6-26.7). In 3 patients (3.7%), conversion to conventional laparotomy was required. Mean operative time was 181.1 (63.1) minutes (95% CI, 166.7-195.5). Mean docking time was 4.5 (1.1) minutes (95% CI, 2.2-2.7). Mean hospital stay was 2.5 (1.1) days (95% CI, 2.2-2.7), and 93% of patients were analgesic-free on postoperative day 2.


CONCLUSIONS
Over a relatively short time using the da Vinci surgical system, we observed a substantial change in our surgical activity. For endometrial cancer, open surgical procedures decreased from 78% to 35%. Moreover, our preliminary data confirm that surgical robotic staging for early-stage endometrial cancer is feasible and safe. Age, obesity, and previous surgery do not seem to be contraindications.
PACE BOM chemotherapy: a 12-week regimen for advanced Hodgkin's disease.

BACKGROUND
This study was designed to evaluate the efficacy and toxicity of a 12-week alternating weekly chemotherapy regimen for advanced Hodgkin's disease. Consolidative irradiation of residual masses was used in selected cases.


PATIENTS AND METHODS
Eighty-three patients with newly diagnosed advanced Hodgkin's disease (bulky stage IIA, stage IIB-IVB) or with progressive disease after extended field radiotherapy for early stage disease were included in this study. The patients were treated for 12 weeks with PACE BOM comprising oral prednisolone together with intravenous doxorubicin, cyclophosphamide and etoposide alternating weekly with intravenous bleomycin, vincristine and methotrexate. Limited field adjuvant radiotherapy was also given to 21 patients with localised persistent radiological abnormalities visible on chest X-ray after chemotherapy. The study end points were overall survival, failure free survival (FFS) and toxicity, particularly with respect to reproductive function.


RESULTS
With a median post treatment follow up of 52 months the actuarial 5-year overall survival is 90% (confidence interval 81%-95%) and FFS is 64% (52%-74%). This treatment was well tolerated and fertility was maintained in a high proportion of young adults.


CONCLUSIONS
The brief duration PACE BOM regimen with or without radiotherapy appears to be comparable in efficacy to other doxorubicin containing regimens, with a favourable toxicity profile. Randomised clinical trials are now needed to evaluate the role of this and comparable initial treatment approaches to advanced Hodgkin's disease.
