The Need for a New Curriculum in Clinical Genetic Education
Authors: Lee Chang-Woo
Published: November 2015

It is becoming increasingly important for medical doctors to have a thorough understanding of human genetics and the ethical, legal, and social implications of genetic testing, counseling, and treatment. As genetic engineering and technology evolves, medical doctors will find themselves called in to counsel patients about a rapidly increasing number of diseases for which genetic testing and treatments are available. Medical doctors will need to master a new set of principles and clinical skills. A lack of knowledge about these issues and problems may lead to serious, lifelong or even fatal negative effects on patients. Medical genetics has moved from the study of rare conditions to the illumination of disorders that impact the entire spectrum of medical practice. This study demonstrates several areas in which medical genetics is clearly an important tool in medical practice and the necessity of establishing new curriculum for clinical genetic education in Korea. Medical students nearing graduation may lack genetic knowledge that is essential for daily practice because genetics has little or no place in clinical teaching. Medical schools should make extensive curriculum changes to increase students’ awareness of clinical genetics and its ethical implications. The medical school curriculum will need creative new approaches to keeping up with the rapid pace of evolution of clinical genetics.

Published: November 2015

Few studies have examined burnout among the faculty of medical schools in the Republic of Korea. The aim of this study was to determine the level of burnout and its associated factors among the faculty members of three medical schools in the Busan-Gyeongnam area, and to summarise the available literature on burnout. We conducted the survey using a validated questionnaire that incorporated the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) as well as questions about demographic characteristics, working experience, health, lifestyle, most time spent and most difficult work, and suicidal ideation and job quitting ideation of the survey participants. MBI-HSS scores were analysed in the three dimensions of emotional exhaustion (EE), depersonalization (De), and personal accomplishment (PA). Through the survey, the 186 professors, 49% among the total, provided data which were included in the present analysis. More than thirty per cent (37.1%) of the professors reported at least 1 symptom of burnout. For burnout dimensions, 11.8% of the respondents scored high for EE burnout, 25.3% for De, and 14.5% for PA, with 1.6% scoring high on all three dimensions of burnout. High burnout was found to be strongly associated with several of the variables under study, especially hours worked per week, self-rated health, career (range, 4 to 9 years), and age (range, 50 to 59 years). The EE score was highest for the professors who chose ‘patient care’ as the most difficult type of work. This study showed that just over one-third of professors have at least 1 symptom of burnout and working more hours per week, short length of work (years), and especially suicidal ideation seem to be associated with the burnout of medical school faculty members in the Busan-Gyeongnam area. In summary, a greater risk of burnout of physicians (including medical professors) seems to be associated with specialties at the front line of care, working more hours per week, work-life imbalance, low self-efficacy, depression, and conflicts with colleagues and patients.
A Case Study on Approaches to Supporting Medical Students with Burnout Experience
Authors: Chung Eun-Kyung , Chay Kee-Oh , Han Eui-Ryoung
Published: November 2015

Medical students often need high levels of specialized institutional and personal support to recover from a burnout experience and to prevent student failure. This study aimed to present approaches to supporting medical students who had experienced burnout using case studies. The study subjects were 45 burnout cases who had been supported by the student support system and committee in one medical school. The factors associated with burnout include poor social network: the lack of belongingness, immature sense of identity, poor mental health, a lack of intrinsic motivation and aptitude, or a major personal crisis. We summarized some tips according to the factors associated with burnout. These tips should provide guidance to organizations and individual support providers to encourage the best quality support for medical students with burnout experiences.
Burnout among Medical Education Specialists in Korean Medical Colleges
Authors: Park Kwihwa , Lee Young-Mee
Published: November 2015

Medical education departments or offices are established in response to public expectations relating to health care, societal trends towards increased accountability, educational developments, increased interest in what to teach and how to educate doctors. However, heavy workloads and mixed feelings towards medical education departments or offices by the other members of a medical school can threaten job satisfaction and increase burnout. The authors investigated the prevalence of burnout among medical education specialists and related issues. Individual in-depth interviews with four medical education specialists were conducted to develop a questionnaire. After content analysis of the interview, the authors generated a survey form with 28 items including 6 categories: motivation to choose medical education as a career, job satisfaction, intention to leave their current position in medical education, the frequency and causes of burnout, and demographics. In September 2013, an email survey was administered to 43 faculty including non-tenure staff who were working in the department/office of medical education in 41 medical colleges in Korea. Of 43 medical education specialists, 25 (60%) returned surveys. Forty three-point-three percent of them felt encouraged when their endeavors generated a visible educational improvement in the medical school. A majority (87%) reported feeling burned out. Fifty percent of them experienced the feeling once or twice a year. The extent of burnout tended to be greater in women, those in their forties, those with non-medical doctor degrees, and in non-tenured staff. To reduce and prevent burnout among medical education specialists, the participants suggested that leadership of medical schools and a systematic approach to medical education should be established. A majority of the medical education specialists reported experiencing burnout, although they were satisfied with their jobs. To reduce their burnout and allow them to focus on their own work in medical education, the following factors are needed: perceptual changes of other members of the college about medical education; more systematic institutional strategies; networking among medical education specialists; and personal efforts for professional development.
How Should Medical Education Be Planned for Medical Students’ Future?
Authors: Jeong Jihoon
Published: November 2015

This study focused on investigating the future medicine and health care industry paradigm shift and suggesting the right direction for the medical education system in order for students to be better prepared in the near future. Here, I will discuss four issues related to the future of medicine: Health 2.0, digital health, personalized medicine, and innovations of the public healthcare system. Every issue has lessons for medical education and teaching for students who major in health professions. However, it is obvious that the present is an important period of time as, currently, we are at an early stage in the future health care environment. Recently, there have been rapid transformations in various fields of medicine. Therefore, if we fail to lead medical education in the right direction, medical students will suffer from major problems in coping with these changes.
Medical Ethics Education: Its Objectives and Curriculum
Authors: Lee Ilhak
Published: November 2015

Medical ethics has been integrated into the curriculum for medical education in Korea for over 30 years now. There have been many attempts to establish standards for the educational objectives and curriculum, including establishing learning outcomes and publishing medical ethics textbooks in Korean. However, this task is not easy for several reasons: the interdisciplinary nature of the subject, educators’ lack of experience, and the lack of a consensus on the criteria that would be effective educational goals. In this article, the author explores (1) the need for reflection on the education itself, (2) two perspectives of medical ethics education, (3) critical perspectives on the effectiveness of the current medical ethics education, and (4) the variety of modalities of medical ethics education. Further, the author proposes a way to teach medical ethics in Korea. The contents and means are closely related to the question of philosophy of medical education: “Should professional ethics education be ‘realistic’ or ‘idealistic’?” Ethics requires educators to be open to new learning experiences and to ethical development. Medical Ethics education should be relevant to everyday clinical experiences and, at the same time provide students and educators to critically review their ethical perspective through reflections.

Published: November 2015

Aim: To evaluate bone health markers and vitamin D status in patients with hyperthyroidism comprehensively, and comparison of same with matched controls. Materials and methods: The study has been done on 30 newly diagnosed hyperthyroid patients and matched controls. Cases were selected after careful exclusion of conditions which adversely affect bone health. Statistical comparisons were performed with Student’s t test. Results: The study group has shown normal calcium (20% had hypocalcemia), normal phosphorus, normal PTH values, raised alkaline phosphatase levels & significant rise in both bone formation (Osteocalcin) and resorption (β-cross laps) markers (P<0.05). In addition 95% of our subjects (patients and controls) were vitamin D deficient (mean-17.2 ng/dl). There is no specific increase in vitamin D deficiency in hyperthyroidism patients. Conclusion: Hyperthyroidism is associated with increased rate of bone remodeling & changes in mineral homeostasis, thereby increases risk of fractures. Associated vitamin D deficiency further deteriorates bone quality. So it is suggested therapeutic vitamin D and calcium supplementation in addition to antithyroid medication. Keywords: hyperthyroidism; vitamin D; osteocalcin; β-crosslaps
Emergency endovascular management of a leaking saccular abdominal aortic aneurysm
Authors: RK Premchand , MD Sadiq Azam
Published: November 2015

Abdominal aortic aneurysms (AAA) are relatively common, potentially life threatening conditions that are often asymptomatic and incidentally detected on routine screening for other problems. Vague abdominal pain and back ache are often the presenting complaints of this disease and are also the commonest complaints that a doctor comes across in the outpatient as well as the emergency room (ER). Hence it is easy to misdiagnose an AAA. A case report illustrating one such patient who presented to the gastroenterologist with vague abdominal pain and backache in whom an abdominal aneurysm was incidentally detected on ultrasound, is presented here. The patient course and complications that developed along with key points to be learnt so as to identify this disease at an early stage and prevent its complications, are discussed.

Published: November 2015

Craniosynostosis is due to premature closure of the cranial sutures. The radiological findings of a 3-year-old girl with a small head, triangular frontal shape, hypertelorism, delayed milestones and syndactyly are presented. A provisional diagnosis of Apert syndrome was made and radiological investigations were performed. Radiographs of both hands and feet showed soft tissue fusion of all digits and synostosis involving the phalanges of both hands and second and third metacarpals of both feet. Radiograph of the skull showed craniosynostosis with turribrachycephaly. Three-dimensional computed tomography (CT) revealed a sagittal, coronal and metopic suture synostosis with exaggerated convolutional markings. MRI of the brain demonstrated agenesis of corpus callosum. Diffusion tensor MRI and fiber tractography (FT) were performed which showed white matter fiber orientation and neuroanatomic configuration of aberrant hemispheric fiber connections.

Published: November 2015

Individualized treatment of patients with diffuse large B cell lymphoma (DLBCL) is within reach given advancements in molecular techniques and the development of novel, targeted drugs. Two biologically distinct subtypes, germinal center B-cell (GCB) DLBCL and activated B-cell (ABC) DLBCL, display differences in outcome and response to therapy. ABC-DLBCL confers poorer prognosis. Several targeted agents show promising activity in this group. Molecular-subtype is a prognostic and therapy-related biomarker that can guide personalized frontline therapy to improve outcomes in DLBCL.

Monólogos a dos voces: "Mascando ortigas" de Itziar Pascual y "El árbol de la esperanza" de Laila Ripoll
Authors: Rovecchio Antón Laeticia
Published: November 2015

En la dramaturgia femenina contemporánea y, más concretamente en el caso de "Mascando ortigas" de Itziar Pascual y "El árbol de la esperanza" de Laila Ripoll, el uso de la forma monologada marca la presencia de un discurso basado en las emociones más íntimas de los personajes, en su identidad. Se trata de una búsqueda de las propias protagonistas, cuyas voces se desdoblan para iniciar un recorrido por la memoria personal e íntima, por las vivencias del pasado, que, indudablemente, condicionan su presente más cercano. Partiendo de las ideas psicoanalíticas de Freud, Lacan y Jung acerca de la figura del doble, en este artículo analizo este desdoblamiento de voces en un mismo personaje que confluye en la creación de un sujeto único.

Las obras sobre la historia de Roma de Metastasio y sus traductores al español con especial atención al jesuita Benito Antonio de Céspedes
Authors: Martín Puente Cristina
Published: November 2015

En el siglo XVIII la Historia de Roma proporcionó a dramaturgos y libretistas argumentos muy atractivos para sus obras, como ya sucediera con Shakespeare, Lope de Vega, Cervantes, Calderón de la Barca, Corneille, Racine, etc. El libretista italiano Metastasio tuvo una gran influencia en el periodo, por el éxito de las representaciones de sus obras, algunas de ellas sobre la Antigua Roma y basadas en autores grecolatinos. De modo que se le puede considerar un intermediario entre los autores de la Antigüedad y los autores españoles que escriben en la transición entre la Ilustración y el Liberalismo. El jesuita Benito Antonio de Céspedes es el más prolífico traductor al español de Metastasio, pero solo se conserva un ejemplar manuscrito de sus traducciones.

O baixo índice pluviométrico é uma das principais características da região semiárida do Brasil. Em particular, verifica-se nesta região uma redução significativa dos totais pluviométricos a partir do ano de 2012, ocasionando sérios danos aos níveis dos reservatórios. O açude Jatobá II, principal fonte hídrica para o município de Princesa Isabel-PB, vem apresentando uma queda considerável em seu volume. Este, por sua vez, foi declarado em situação de emergência no ano de 2015.  Logo, fazendo uso de ferramentas de geoprocessamento, busca-se a partir do desenvolvimento da presente pesquisa analisar o real cenário da microbacia do açude Jatobá II. Foi utilizado o Índice de Vegetação por Diferença Normalizada – IVDN para se obter informações sobre a vegetação na microbacia entre os anos de 2011 e 2013, além de imagens de alta resolução para identificar a redução na lâmina d’água do açude entre os anos de 2010 (ano de cheia) e 2014 (ano de seca). Dados hidrometeorológicos auxiliaram a perceber que os períodos com desvios negativos à pluviometria média climatológica coincidiram com a redução no volume do açude. Por fim, a população, a economia e o meio ambiente de Princesa Isabel estão a passar por dificuldades causadas pela seca.

Geoprocessing techniques in supporting to drought analysis in the micro basin of dam Jatobá II

Abstract: The low rainfall is one of the main characteristics in the Brazil semiarid region. In particular, it is noted in this region a significant reduction of total rainfall from 2012, causing serious damages to the reservoir levels. The Jatobá II dam, main water source in Princesa Isabel municipality of Paraíba state, has shown a considerable fall in volume. This, in turn, was declared in emergency situation in 2015. Thus, using geoprocessing tools it aims from the development of the present research to analyze the real scenario in the micro watershed Jatobá II dam. Was used Vegetation Index Normalized Difference - NDVI to obtain information about vegetation in the micro watershed between the years 2011 and 2013, as well as high-resolution images to identify the reduction in water surface of the dam between 2010 (year of abundance) and 2014 (year of drought). Hydrometeorological data helped to realize that periods with negative deviations from the climatological average rainfall coincided with the reduction in reservoir volume. Finally, the population, the economy and the environment of Princesa Isabel are experiencing difficulties caused by drought.

Published: November 2015

O setor madeireiro do Brasil produz uma grande quantidade de resíduos, causando danos ao meio ambiente. Diante desse cenário, objetivou-se produzir e avaliar briquetes a partir de serragem de madeira produzida por uma marcenaria localizada no extremo sul do Piauí, visando seu uso tecnológico como fonte energética. Os resíduos utilizados no trabalho são das espécies de Ipê roxo (Tabebuia impetiginosa M.), Pinus sp. L. e Violeta (Daugerbia cearensis D.). A serragem foi coletada em uma marcenaria localizada no município de Corrente-PI. Utilizou-se uma prensa hidráulica de 15 Ton, adaptada. Os briquetes foram avaliados em relação à densidade aparente, densidade a granel, análise química imediata, PCS, PCI, e ICOM. Os briquetes apresentaram densidade aparente média 1,229 g/cm³ (Pinus sp.), 1,225 g/cm³ (Violeta) e 1,139 g/cm³ para o Ipê roxo. Os briquetes da espécie Ipê roxo obteve o maior ICOM, com 0,3961. Observou-se pouca diferença nas dimensões, densidade e ICOM dos briquetes, quando utilizado o teste de Tukey a 5% de significância. Com base na regressão linear, a densidade está correlacionada positivamente com o ICOM. Os briquetes produzidos mostraram-se como uma nova fonte energética a ser utilizada, ajudando ainda mitigar os impactos causados pela exploração predatória das florestas nativas.

Production of briquettes from forest species
Abstract: The timber sector in Brazil produces a lot of residues, causing damage to the environment. In this scenario, the objective was to produce and evaluate briquettes from sawdust produced by a carpentry shop located on the southern edge of Piauí, aiming its technological use as an energy source. Residues used at work are the species of Ipê roxo (Tabebuia impetiginosa M.), Pinus sp. L. and Violeta (Daugerbia cearensis D.). The sawdust was collected in a carpentry shop in the municipality of Corrente-PI. We used a 15 ton hydraulic press adapted. The briquettes were evaluated for bulk density, bulk density, chemical analysis, PCS, PCI, and ICOM. The briquettes showed apparent medium density 1,229 g/cm³ (Pinus sp.), 1.225 g/cm³ (Violeta) and 1.139 g/cm³ to  Ipê roxo. The Ipê roxo kind of briquettes had the highest ICOM, with 0.3961. There was little difference in dimensions, density and ICOM of briquettes, when using the Tukey test at 5% significance level. Based on linear regression, the density is positively correlated with the ICOM. The briquettes produced appeared as a new energy source to be used while helping mitigate the impacts caused by the predatory exploitation of native forests.

Reinforcing quartz mesh applications for prophylaxis of fractures of bases of laminar removable dentures for patients with perforating defects of the palate
Authors: Карасева В. , Karaseva V.
Published: November 2015

In the surgical treatment of tumors, accompanied by resection of the upper jaw, sometimes the palate defects are formed, leading to the post of the mouth with the nasal cavity. Such defects are restored mostly with laminar removable dentures with a plastic basis. Clinical features (the quantity, topography and shape of the defect, as well as the amount and condition of the remaining teeth) and properties of acrylic plastic (lack of strength) lead to breakage of the basis, which negatively affects the functional viability of the prosthesis and significantly impairs the quality of life of `difficult-jaw` patients. On the example of clinical cases are noticed features and stages of dentures manufacturing in patients with a through defect of the palate. Authors of the study offered a method for strengthening the bases of dentures and solving the problem of frequent breakdowns through the use of a reinforcing quartz mesh. It is made the evaluation of results of the conducted orthopedic treatment.
Documenting Trends in Water Use and Conservation Practices on U.S. Golf Courses
Authors: Gelernter Wendy D. , Stowell Larry J. , Johnson Mark E. , Brown Clark D. , Beditz Joseph F.
Published: November 2015

Since an initial survey was conducted in 2006, U.S. golf courses have reduced their water use by 21.8%, from a projected 2.379 million acre‐feet/year to 1.859 million acre‐feet of water per year. Factors contributing to this decrease include voluntary reductions in number of irrigated acres, reductions in number of golf facilities, and water conservation practices. These practices allowed U.S. golf courses to use less water than predicted by reference evapotranspiration (ETo) values. There is dramatic regional variation in water use patterns across the United States. The median amount of water used by an 18‐hole golf course was highest in the Southwest (3.87 acre‐feet/acre per year) and lowest in the Transition zone (cool‐ to warm‐season grass adaption areas) (0.60 acre‐feet/acre per year), and water use ranged from no irrigation to >9 acre‐feet/acre per year on a course‐by‐course basis. Regional variation was most heavily influenced by climate, due to the broad range of ETo and precipitation values among the study's seven agronomic regions. Recycled water use has increased to approximately 25% of all water used on golf courses in 2013, from 14.7% in 2005. Future decreases in golf course water use will likely depend on further development of water budgeting and water management plans, adoption of monitoring technology, improved irrigation efficiency, and further reductions in irrigated acreages.
Traumatic Rupture of the Distal Triceps Tendon (A Series of 7 Cases)
Authors: Neumann H. , Schulz A.-P. , Breer S. , Faschingbauer M. , Kienast B.
Published: November 2015

Even non-traumatic ruptures of the triceps tendon are rare, surgical therapy should be recommended in all
cases, because of poor results after non-operative treatment. A golden standard for the surgical procedure is not
established. A small series of traumatic distal tendon ruptures was treated surgical in our hospital and was followed up
after 12 months concerning their function. Very good and good results could be found with a strong reintegration of the
tendon by using transosseus sutures with non resorbable suture material. The refixation with suture anchors showed
disappointing results with early pull-outs of the anchor. Revision with screw augmentation with a washer had to be
performed. Concerning the biomechanical forces, which show up on the olecranon (up to 40 NM), the refixation of the
triceps tendon has proved to be extremely resistant against pull out forces. The good results by using non absorbable
transosseus sutures led to a standardized procedure in our trauma center, even the rupture is not traumatic.

Background

In the field of forensic medicine, it is very difficult to know prior to autopsy what kind of virus has infected a body.

Objective

We assessed the potential of the genome profiling (GP) method, which was developed in the field of bioengineering, to identify viruses belonging to one species.

Method

Two species in the same family, JC and BK viruses, were used in this study. Using plasmid samples, we compared the findings of molecular phylogenetic analysis using conventional genome sequencing with the results of cluster analysis using the random PCR-based GP method and discussed whether the GP method can be used to determine viral species.

Results

It was possible to distinguish these two different viral species. In addition to this, in our trial we could also detect the JC virus from a clinical sample.

Conclusion

This method does not require special reagent sets for each viral species. Though our findings are still in the trial period, the GP method may be a simple, easy, and economical tool to detect viral species in the near future.

Published: November 2015

In this work, we successfully applied the Fray-Farthing-Chen Cambridge
electro-reduction process on the preparation of chromium from chromium
oxide, and for the first time, the synthesis of ferrochromium alloy from
chromium oxide and iron oxide mixture and the chromite ore in molten calcium
chloride. The present work systematically investigated the influences of
sintered temperature of the solid precursor, electrochemical potential,
electrolysis temperature and time on the products by using a set of advanced
characterization techniques, including XRD and SEM/EDS analyses. In
particular, our results show that this process is energy-friendly and
technically-feasible for the direct extraction of ferrochromium alloy from
chromite ore. Our findings thus provide useful insights for designing a
novel green process to produce ferrochromium alloy from low-grade chromite
ore or stainless steel slag.
Blogs as Research and Teaching Resources for Accounting Academics
Authors: Gray Glen L.
Published: November 2015

A blog is a website maintained by an individual or group of individuals that includes observations and opinions regarding a specific subject matter. This paper explores the opportunities and issues regarding blogs as accounting research and teaching resources. While locating applicable blogs is challenging, they can be valuable resources regarding current events and their archives provide perspectives that can cover several years. For research, blogs are a continuous and timely source of research ideas and should be part of any literature review. Blogs that criticize current accounting practice not only identify issues ripe for research, but also frequently present recommendations to address those issues. Academics can transform those criticisms and recommendations into testable questions or hypotheses to investigate using various qualitative and quantitative research methods. As teaching resources, blogs provide an opportunity for students to analyze and evaluate others' opinions, which should improve students' critical thinking and make them cognizant and conversant in accounting subject matters. Students can also create their own blogs as a form of reflection.
Resolving the Magnetic Asymmetry of the Inner Space in Self-assembled Dimeric Capsules Based on Tetraurea-calix[4]pyrrole Components
Authors: Espelt Mónica , Aragay Gemma , Ballester Pablo
Published: November 2015

The encapsulation of N,N, N',N'-tetramethyl-1,5-pentanediamine-N,N'-dioxide 2 in a non-chiral capsular assembly formed by dimerization of tetraurea-calix[4]pyrrole 1a produced the observation of the N-methyl groups
of the encapsulated guest as two separated singlets resonating highly upfield in the 1H NMR spectrum. In order to clarify the origin of the observed signal splitting we assembled and studied a series of structurally related dimeric capsules. We used the tetraurea-calix[4]pyrrole
1a , the enantiomerically pure tetraurea-calix[4] pyrrole R-1b and the tetraurea-bisloop calix[4]pyrrole 1c as components of the produced assemblies. The 1H NMR spectra of the assembled encapsulation complexes with bis-N-oxide 2 evidenced
diverse splitting patterns of the N-methyl groups. In addition, 2D EXSY/ROESY NMR experiments revealed the existence of chemical exchange processes involving the separated methyl signals of the encapsulated guest. The capsular assemblies were mainly stabilized by a belt of eight head-to-tail
hydrogen-bonded urea groups. The interconversion between the two senses of rotation of the unidirectionally oriented urea groups was slow on the 1H NMR timescale. These characteristics determined the appearance of a new asymmetry element (supramolecular conformational chirality)
in the assemblies that accounted for some of the magnetic asymmetries featured by the capsule's inner space. The racemization of the supramolecular chirality element was fast on the EXSY timescale and produced the chemical exchange processes detected for the encapsulation complexes.

Trajectory Data and Flow Characteristics of Mixed Traffic
Authors: Kanagaraj Venkatesan , Asaithambi Gowri , Toledo Tomer , Lee Tzu-Chang
Published: November 2015

Models of driving behavior (e.g., car following and lane changing) describe the longitudinal and lateral movements of vehicles in the traffic stream. Calibration and validation of these models require detailed vehicle trajectory data. Trajectory data about traffic in cities in the developing world are not publicly available. These cities are characterized by a heterogeneous mix of vehicle types and by a lack of lane discipline. This paper reports on an effort to create a data set of vehicle trajectory data in mixed traffic and on the first results of analysis of these data. The data were collected through video photography in an urban midblock road section in Chennai, India. The trajectory data were extracted from the video sequences with specialized software, and the locally weighted regression method was used to process the data to reduce measurement errors and obtain continuous position, speed, and acceleration functions. The collected data were freely available at http://toledo.net.technion.ac.il/downloads . The traffic flow characteristics of these trajectories, such as speed, acceleration and deceleration, and longitudinal spacing, were investigated. The results show statistically significant differences between the various vehicle types in travel speeds, accelerations, distance keeping, and selection of lateral positions on the roadway. The results further indicate that vehicles, particularly motorcycles, move substantially in the lateral direction and that in a substantial fraction of the observations, drivers are not strictly following their leaders. The results suggest directions for development of a driving behavior model for mixed traffic streams.
Real-Time Traffic Network State Prediction for Proactive Traffic Management
Authors: Hashemi Hossein , Abdelghany Khaled
Published: November 2015

Real-time traffic management systems with integrated proactive decision support capabilities are expected to operate with ( a) limited prediction accuracy ( b) decision-making latency, and ( c) partial coverage of the managed area. Such deficiencies are difficult to avoid in most real-world traffic network management applications, and there is a need to quantify the effect of these deficiencies on the performance of traffic network management systems. This paper studies the effectiveness of a proactive traffic management system. Various levels of prediction accuracy of the traffic network state, decision-making latency, and partial area coverage are considered. A traffic management system that emulates real-time operations is developed. The system adopts a closed-loop rolling horizon framework, which integrates network state estimation and prediction modules as well as decision support capabilities. A set of simulation experiments considers a hypothetical highway network. The results show that the effectiveness of the traffic management system can be affected by the deficiencies. However, the impact could be smaller if these deficiencies are kept under certain levels.
Capacity Drop
Authors: Yuan Kai , Knoop Victor L. , Hoogendoorn Serge P.
Published: November 2015

It has been empirically observed for years that the queue discharge rate is lower than the prequeue capacity. This difference is called the capacity drop. The magnitude of capacity drop varies over a wide range, depending on the local traffic conditions. However, it is unknown what determines the capacity drop value. No thorough empirical analysis has yet revealed a reliable relationship between the capacity drop and the congestion level. This paper fills the gap by revealing, through empirical analysis, the relationship between vehicle speed in congestion and the queue discharge rate. The research studies congested states in which speed ranges from 6 to 60 km/h. The queue discharge rate is shown to increase considerably with increasing speed in the congestion. In contrast to previous research, this study bases the relationship on empirical data collected on freeways, and the data present a sufficiently large observation sample. A discussion about the influence of weather and study site characteristics on the discharge rate indicates that the relationship needs site-specific calibrations. This study provides a better prediction of capacity drop and a better theoretical understanding of the fluctuations in capacity drop.
