KMUT – Project Management Toolbox
Authors: Quade Stefanie , Birkenkrahe Marcus , Habermann Frank 
Published: May 2013

Small and medium-sized enterprises (SMEs) are increasingly dealing with international projects and distributed (sometimes even virtual) teams. Consequently, they are looking for project management (PM) tools which fit their respective needs regarding communication and collaboration. Unfortunately, the majority of the PM software available in the market seems to be oversized for this purpose. Instead most project managers are requesting smart solutions that allow quick implementation without any significant organisational or technical change.
Within the research project InterComp SME 2.0 we combine theoretical research and real business to develop hands-on solutions for SMEs. This paper describes an effective approach for a â??PM Toolboxâ? that allows finding the right project tool for a specific project need. The toolbox has been developed in due consideration of user stories gained from business practice, a more detailed SME business survey, a theoretical PM meta model and a market of PM tools.
Since the business survey revealed that the readiness to use and test a â??toolboxâ? is highly dependent on the type of user and his or her technical background, we designed the system based on use cases and user typology. As a result, we suggest a framework of open, freely available, easy-to-install, single and multi purpose PM software tools which can be selected solely on a need basis. With this free platform we want to guide practitioners through the tool jungle with the potential to grow into a lively community.
Pinvox Method to Enhance Self-Study in Blended Learning: Experiences at University of Bucharest
Authors: Canessa Enrique , Logofatu Bodgan 
Published: May 2013

We report results on the first large-scale trial
implementation of the new Pinvox algorithm carried out at
the Department of Distance Learning (DL) of the University
of Bucharest to encourage hundreds of Bachelor and Master
DL students to perform their self-study. Pinvox is an open
source tool that helps to ensure "on-line attendanceâ? and to
induce â??student's attentionâ? through the identification of
different, randomly selected, brief audio PINs embedded
automatically in videos or audio files assigned to each
student. We argue that checking how students watched a
video lecture has many advantages in the formative
assessment work.
A Patient with Hashimoto's Encephalopathy Presenting with Convulsive Seizure Alone as the Initial Symptom

Published: May 2013

A 71-year-old Japanese woman with Sjögren syndrome, Hashimoto's disease and a 6-month history of cognitive impairment was admitted to our hospital because of consciousness disturbance and convulsion. Her convulsive seizure disappeared by intravenous administration of diazepam following carbamazepine, and conscious level became alert the next day. But, her cognitive function was persistently deteriorated, and a score of mini-mental state examination (MMSE) was 17/30 points. Magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) of the brain did not show any abnormal findings. The electroencephalogram showed increased slow waves in bilateral parieto-occipital regions. Serum anti-thyroglobulin antibodies were elevated (1780 U/ml), but thyroid function was within the normal range. In addition, anti-NAE (NH2-terminal of α-enolase) antibodies were positive. We diagnosed Hashimoto's encephalopathy, and started steroid therapy. Her cognitive function gradually improved after steroid therapy, and convulsive seizure did not recur until 3 months later. We emphasize that Hashimoto's encephalopathy should be considered even in patients with convulsive seizure of adult onset without thyroid dysfunction.
An Analysis of Japanese versus American Automakers' Supplier Relationships in Thailand
Authors: Mejza Michael , Laosirihongthong Tritos , Prajogo Daniel I. 
Published: May 2013

Abstract
In the context of the US automobile market, past comparisons of automakers' supplier management practices show Japanese assemblers besting American counterparts along a number of dimensions despite American automakers' efforts to emulate Japanese practices. But recent studies suggest emergent American practices differ from traditional Japanese vertical keiretsu practices. Such a departure could affect American-allied Japanese automakers in Thailand, a major global automotive export hub. This exploratory study of 383 automobile part and component suppliers in Thailand finds suppliers to Japanese assemblers distinguishable by higher priorities placed on delivery and flexibility, but on an equal basis with suppliers to American assemblers in terms of cost and quality priorities.
Quand les documentaristes de l’ONF « fictionnalisent » les potentialités télévisuelles
Authors: Scheppler Gwenn 
Published: May 2013

En 1953, l’ONF inaugure ses deux premières séries documentaires spécialement conçues pour la télévision de Radio-Canada :Sur le vif/On the SpotetRegards sur le Canada/Window on Canada. Ces deux séries hebdomadaires, qui vont garder l’antenne jusqu’en 1956 pour la première et 1955 pour la seconde, vont connaître un accueil mitigé de la part du public, en particulierRegards sur le Canada. Chacune de ces séries est différente dans son principe, même si les artisans de l’une sont souvent ceux de l’autre (notamment Bernard Devlin). Alors queSur le viffonctionne à la manière d’un reportage divertissant simulant le direct télévisuel,Regards sur le Canadafonctionne plutôt à la manière d’un ciné-club éducatif, où un présentateur-conférencier fait jouer d’anciens films qu’il commente ensuite avec des invités sur un plateau de télévision. Le dispositif de ces deux séries est donc significatif, d’un point de vue historique tout autant qu’esthétique : ils marquent, chacun à sa façon, une transition entre le cinéma et la télévision, une phase d’adaptation et d’expérimentation que l’auteur documente et analyse.
Autism spectrum disorders: The quest for genetic syndromes
Authors: Zafeiriou Dimitrios I. , Ververi Athina , Dafoulis Vaios , Kalyva Efrosini , Vargiami Euthymia 
Published: May 2013

AbstractAutism spectrum disorders (ASD) are a heterogeneous group of neurodevelopmental disabilities with various etiologies, but with a heritability estimate of more than 90%. Although the strong correlation between autism and genetic factors has been long established, the exact genetic background of ASD remains unclear. A number of genetic syndromes manifest ASD at higher than expected frequencies compared to the general population. These syndromes account for more than 10% of all ASD cases and include tuberous sclerosis, fragile X, Down, neurofibromatosis, Angelman, Prader–Willi, Williams, Duchenne, etc. Clinicians are increasingly required to recognize genetic disorders in individuals with ASD, in terms of providing proper care and prognosis to the patient, as well as genetic counseling to the family. Vice versa, it is equally essential to identify ASD in patients with genetic syndromes, in order to ensure correct management and appropriate educational placement. During investigation of genetic syndromes, a number of issues emerge: impact of intellectual disability in ASD diagnoses, identification of autistic subphenotypes and differences from idiopathic autism, validity of assessment tools designed for idiopathic autism, possible mechanisms for the association with ASD, etc. Findings from the study of genetic syndromes are incorporated into the ongoing research on autism etiology and pathogenesis; different syndromes converge upon common biological backgrounds (such as disrupted molecular pathways and brain circuitries), which probably account for their comorbidity with autism. This review paper critically examines the prevalence and characteristics of the main genetic syndromes, as well as the possible mechanisms for their association with ASD. © 2013 Wiley Periodicals, Inc. © 2013 Wiley Periodicals, Inc.
Substantial genetic link between iq and working memory: Implications for molecular genetic studies on schizophrenia. the european twin study of schizophrenia (EUTwinsS)

Published: May 2013

AbstractWhile evidence is accumulating to support specific neurocognitive deficits as putative endophenotypes for schizophrenia, the heritability of these deficits in healthy subjects and whether they share common genetic influences, is not well established. In the present study, 529 healthy adult twins from two centers within the European Twin Study Network on Schizophrenia (EUTwinsS) were assessed on two domains that are consistently found to be particularly compromised in schizophrenia. Specifically, Intellectual Quotient Score (IQ) and the Letter–Number Sequencing Test (LNS), a measure of working memory, were measured in all twins. Latent variable components were explored through structural equation modeling, and common genetic underpinnings were examined using bivariate analyses. Results showed that the phenotypic correlation between IQ and working memory was almost entirely attributed to shared genetic variance (95.5%). We discuss the potential use of a combined measure of IQ and working memory to improve the power of molecular studies in detecting the genetic mechanisms underlying schizophrenia. © 2013 Wiley Periodicals, Inc. © 2013 Wiley Periodicals, Inc.
A novel membrane diffusion process for the preparation of chitosan/hydroxyapatite composite
Authors: Tachaboonyakiat Wanpen , Sahawat Dusida 
Published: May 2013

ABSTRACTThe aim of this study was to create a suitable method to hybridize hydroxyapatite into chitosan solution with a good dispersion of inorganic matter in the organic phase. The preparation of chitosan/hydroxyapatite composites via a membrane diffusion process was evaluated and optimized. A diffusion time of 3 days, and chitosan, calcium chloride, and disodium hydrogen phosphate with the concentrations of 1.75 % w/v, 0.20M, and 0.12M, respectively, were found to be the optimal conditions. Scanning electron microscope observations showed a cluster of needle‐shaped hydroxyapatite across the composite film when synthesized with 0.2M of calcium chloride solution and 0.12M of disodium hydrogen phosphate solution, whereas hydroxyapatite was observed in larger diffuse aggregates when synthesized at a higher concentration of both solutions. Attenuated total reflection‐Fourier transform infrared spectrophotometer and X‐ray diffraction analyses displayed the specific peaks for the phosphate group and 2‐θ peaks of hydroxyapatite crystals, respectively. These results indicated that hydroxyapatite can be hybridized into a chitosan solution with good dispersion through a membrane diffusion process. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Water state in chemically and physically crosslinked chitosan membranes
Authors: Ostrowska‐Czubenko Jadwiga , Pieróg Milena , Gierszewska‐Drużyńska Magdalena 
Published: May 2013

ABSTRACTChemically and physically crosslinked chitosan membranes were prepared by treating chitosan (Ch) with glutaraldehyde (GA) and sulfuric acid (SA). FTIR and XRD results were employed to confirm the formation of covalent and ionic crosslinks between Ch, GA, and SA. The states of water in non‐crosslinked and covalently and ionically crosslinked chitosan membranes containing different amount of water were investigated by low temperature differential scanning calorimetry measurements. The equilibrium swelling in water was examined gravimetrically. Two types of water were found in the polymer samples, i.e., freezing water and non‐freezing water. The effect of crosslinking process on water state and water uptake was analyzed. The water uptake decreased after chitosan crosslinking with GA, but significantly increased after later crosslinking with SA. The amount of non‐freezing water was generally smaller in crosslinked membranes. An impact of molecular and supermolecular structure on water uptake and state of water in non‐crosslinked and crosslinked chitosan membranes was discussed. © 2013 Wiley Periodicals, Inc. J. Appl.

Published: May 2013

AbstractA series of compounds derived from 4,5‐dihydro‐1H‐1,2,4‐triazol‐5‐one were synthesized and characterized by spectral data. The 12 new compounds were analyzed for their potential in vitro antioxidant activities by three different methods. Compound 4f showed the best activity for the iron binding. In addition, the compounds 4 were titrated potentiometrically with tetrabutylammonium hydroxide in non‐aqueous solvents. The RP‐HPLC capacity factors (k′) of the series were also determined on a C18 column, with methanol/water as the mobile phase. The correlation between log k′ with the percentage of methanol in the mobile phase was used for the determination of the log kw values for these compounds. The antimicrobial activities of these compounds were also screened against bacteria and yeast.
Meta-analysis of contemporary short- and long-term mortality rates in patients diagnosed with critical leg ischaemia
Authors: Rollins K E , Jackson D , Coughlin P A 
Published: May 2013

Abstract

Background
Critical leg ischaemia (CLI) has been associated with high mortality rates. There is a lack of contemporary data on both short- and long-term mortality rates in patients diagnosed with CLI.

Methods
This was a systematic literature search for studies prospectively reporting mortality in patients diagnosed with CLI. Meta-analysis and meta-regression models were developed to determine overall mortality rates and specific patient-related factors that were associated with death.

Results
A total of 50 studies were included in the analysis The estimated probability of all-cause mortality in patients with CLI was 3·7 per cent at 30 days, 17·5 per cent at 1 year, 35·1 per cent at 3 years and 46·2 per cent at 5 years. Men had a statistically significant survival benefit at 30 days and 3 years. The presence of ischaemic heart disease, tissue loss and older age resulted in a higher probability of death at 3 years.

Conclusion
Early mortality rates in patients diagnosed with CLI have improved slightly compared with previous historical data, but long-term mortality rates are still high.
Expertise-based randomized clinical trial of laparoscopic versus small-incision open cholecystectomy
Authors: Rosenmüller M H , Thorén Örnberg M , Myrnäs T , Lundberg O , Nilsson E , Haapamäki M M 
Published: May 2013

Abstract

Background
Several randomized clinical trials have compared laparoscopic cholecystectomy (LC) and small-incision open cholecystectomy (SIOC). Most have had wide exclusion criteria and none was expertise-based. The aim of this expertise-based randomized trial was to compare healthcare costs, quality of life (QoL), pain and clinical outcomes after LC and SIOC.

Methods
Patients scheduled for cholecystectomy were randomized to treatment by one of two teams of surgeons with a preference for either LC or SIOC. Each team performed their specific method (SIOC or LC) as a first-choice operation, but converted to open cholecystectomy and common bile duct exploration when necessary. Intraoperative cholangiography was carried out routinely. The intention was to include all patients undergoing cholecystectomy, including emergency operations and procedures involving surgical training for residents.

Results
Some 74·9 per cent of all patients undergoing cholecystectomy were included. Of 355 patients randomized, 333 were analysed. Self-estimated QoL scores in 258 patients, analysed by the area under the curve method, were significantly lower in the SIOC group at 1 month after surgery: median 2326 (95 per cent confidence interval 2187 to 2391) compared with 2411 (2334 to 2502) for the LC group (P = 0·030). The mean(s.d.) duration of operation was shorter for SIOC: 97(41) versus 120(48) min (P &lt; 0·001). There were no significant differences between the groups in conversion rate, pain, complications, length of hospital stay or readmissions.

Conclusion
SIOC had comparable surgical results but slightly worse short-term QoL compared with LC. Registration number: NCT00370344 (http://www.clinicaltrials.gov).
Rigid‐motion‐inspired liquid character animation
Authors: Zhang Guijuan , Lu Dianjie , Zhu Dengming , Lv Lei , Liu Hong , Meng Xiangxu 
Published: May 2013

ABSTRACTWe present a rigid‐motion‐inspired method for animating liquid characters in this paper. Our method allows an animator to control the motion of liquid characters with motion capture data that is widely used in rigid body animation. It animates the most visual interesting part of liquid character, that is, to preserve character's shape as well as produce enough liquid details. To this end, we build a two‐layer model to represent the character by two coaxial layers: the rigid kernel and the liquid shell. Different control paradigms are used for the two layers instead of applying homogeneous force that is common in previous approaches. By embedding the control algorithm to the Navier–Stokes equations, we compute the fluid velocity that drives the motion of the liquid character. Results show that the method is easy and intuitive to use while incurring little additional cost.Copyright © 2013 John Wiley & Sons, Ltd.
Draft‐space warping: grading of clothes based on parametrized draft
Authors: Jeong Moon‐Hwan , Ko Hyeong‐Seok 
Published: May 2013

ABSTRACTThis paper presents a novel framework for garment grading. In CG, an extensive amount of study has been carried out to clothe human characters, but little attention has been taken to the grading problem itself. For the development of a grading technique, we obtained the insight from the process of drawing the patternmaking draft (sloper) in the clothing field. Noting that the draft can be completely determined by supplying the primary body sizes, we abstract the draft construction process as a computer procedure, which we call the parametrized draft. With the parametrized draft, we develop a grading method based on the draft‐space warping, which takes three steps: (i) draft‐space encoding, (ii) target draft construction, then (iii) draft‐space decoding. The proposed grading method can be performed instantly for any given body without calling for the user's intervention. With experimental results, we show that the new grading framework can bring an improvement to garment grading. Copyright © 2013 John Wiley & Sons, Ltd.
Simulating realistic crowd based on agent trajectories
Authors: Sun Libo , Li Xiaona , Qin Wenhu 
Published: May 2013

ABSTRACTThis paper presents a model for simulating realistic crowd behaviors at low computation cost. The proposed model is inspired by video data. In our approach, we first classify the crowd into two categories: main and background characters. Whether the agents are main characters or not is influenced by two factors, one is the agent's trajectories and the other one is the change of the environment. In the second stage, we adopt two approaches to simulate the behaviors of main and background characters. Main characters are intelligent agents with the perception, the memory, the planning, and the psychology so that they can make decisions themselves. Background characters are informed of the behavior options for execution by the “smart environment.” Finally, we simulate the road‐crossing scenario in a three‐dimensional virtual environment. The experimental results demonstrate that our approach not only well reflects the characteristics of agent behaviors but also reduces the computation complexity of simulating realistic crowd.

Published: May 2013

ABSTRACTWe present a method to make an accurate and dense reconstruction from the input of video captured by a free moving handheld camera in real time. By the method firstly, the positions of the camera and sparse 3D points are estimated by simultaneous localization mapping. Then the depth maps of selected reference frames are computed from corresponding camera bundles. Lastly a novel linear algorithm is also proposed to integrate all the depth maps into dense meshes partially. The main contributions of this paper are in the following points: the reference frames and corresponding camera bundles are able to be selected automatically, then accurate and smooth depth maps are generated in real time, and the depth maps are merged into a dense mesh by using a linear algorithm based on the error clouds optimization. Our algorithm is implemented on dual CPU and graphics processing unit in a parallel framework for improving the performance. Copyright © 2013 John Wiley & Sons, Ltd.
Flexible and rapid animation of brittle fracture using the smoothed particle hydrodynamics formulation
Authors: Chen Feibin , Wang Changbo , Xie Buying , Qin Hong 
Published: May 2013

ABSTRACTThis paper presents a hybrid animation approach to the flexible and rapid crack simulation of brittle material. At the physical level, the local stress tensors induced by collision are analyzed by using the smoothed particle hydrodynamics (SPH) formulation. Specifically, in order to determine the internal stress when rigid bodies collide with each other or neighboring environments, we treat all of them as completely rigid body that has infinite stiffness and then evaluate virtual displacement for colliding particles. At the geometric level, in order to faithfully maintain the fracture interface during the crack simulation, we utilize an efficient shape representation of solid based on the tetrahedral decomposition of the original solid geometry. This novel hybrid approach resorts to local particle models, whose goal is to avoid heavy computational burden during crack interface updating and topological changing, and meanwhile, it facilitates the user‐initiated interactive control during the crack generation and propagation. Our animation experiments demonstrate the effectiveness of our novel particle‐based method to simulate the crack of brittle material. Copyright © 2013 John Wiley & Sons, Ltd.
Relighting abstracted image via salient edge‐guided luminance field optimization
Authors: Liu Chunxiao , Li Hong , Peng Qunsheng , Wang Xun , Wu Enhua 
Published: May 2013

ABSTRACTBecause existing image abstraction systems can hardly incorporate with the changing light, we present an integrated image abstraction and relighting rendering system, which is based on a salient edge‐guided luminance field optimization approach. For an input image, we first adopt a sparsity prior‐based illumination decomposition method to remove its original illumination and have an intrinsic image. Meanwhile, we iteratively extract the salient edge inside by employing a message‐passing strategy. Then, we simplify this image with a proposed salient edge‐guided image abstraction optimization algorithm in the luminance field. Finally, we put forward a salient edge‐guided image relighting optimization method to simulate the effect of dynamic lighting along different directions. Experiment results show that our system can artistically adjust the illumination of the abstracted image and makes it more vivid. Copyright © 2013 John Wiley & Sons, Ltd.
