Published: December 2019

Abstract
The identification of garbage at several points along the Badung river shows a low level of public awareness of the environment. The origin of the contents of the garbage in the Badung river comes from various human activities such as industry, household and nature. Although there is a trash rack, but it is not optimal in reducing plastic waste carried on the river. There are several reasons that cause people to throw garbage into the river. Among other things, disposing of garbage into the river is considered more practical and freer, the lack of garbage disposal facilities around the river and has become a culture. Therefore, research was conducted on community behaviour in disposing of garbage along the Badung river. The results showed trigger factors variable with a very influential factor, namely the existence of a disease of 79%. And as many as 5% of the people feel that the availability of Temporary Disposal Site facilities has no effect. The waste management system will be managed directly by the Waste Self-Management Group in each village, as an effort to build an integrated system. It also educates the public how to sort, manage and utilize waste. With the proper governance, of course, it can reduce the volume of waste to landfill.

Published: December 2019

Abstract
Modular steel structure with a 100% assembly rate, is one of significant methods to realize building industrialization. It has an extensive application prospect due to the short construction cycle and small impact on the surrounding environment.. Based on the characteristics of modular architecture, this paper takes the work of the 2018 Chinese College Students Steel Structure Innovation Competition as an example to discuss the design possibilities of student dormitories. However, due to production mode and transportation conditions, modular building also has some limitations for application. Through research on design, this paper makes the breakthroughs in the design limitations of modular building.
Research on Body and Architecture
Authors: Li Linxue , Zhang Qi , He Meiting 
Published: December 2019

Abstract
The topic of body is closely related to architecture. Based on the Anthony Vidler’s and others’ study on the relationship between body and architecture, this paper studies the relationship between body and architecture from a historical perspective, including the concept of body in philosophical context, the projection of body in classical architecture, and the metaphor of body in postmodern architecture. The theory of body has had an important influence on the architectural form at the beginning of the development of architecture, and then expanded the understanding of architecture at different stages. Recently, with the environmental issues and sustainable development getting more and more attention, the relationship between body theory and architecture will also face new development potentials and opportunities. Reconsidering architecture from the perspective of body perception and paying attention to the interaction between psychology and environment is an opportunity for the development of body and architecture, which may lead to theoretical and practical guidance of more contemporary significance.

Abstract
The scouring phenomenon is one of the causes of bridge damage in the world. This scouring phenomenon has various kinds such as local scour and contraction scour. There are various equations for calculating pier scouring, including Colorado State University equations, Frochelin and others. A computer program is needed to facilitate the calculation of pier scouring, HEC-RAS based on Finite Difference Method was chosen to simulate pier scouring problem. Up until now, there has not been any research to quantify the uncertainty of bridge scour HEC RAS based of experiment. The objective of this study to validate the pier scouring calculation by comparing the expected value of pier scouring results of HEC-RAS with an experiment and CSU equation. The HEC-RAS was evaluated using experimental data that had been carried out by Shukri in 2017. Furthermore purpose of this study is determining which the variable that is sensitive to the depth of scouring. The sensitive variables are determined by performing sensitivity analysis of the variables on HEC-RAS using the Pearson correlation coefficient method and regression analysis. Error propagation is done to get the uncertainty value from pier scouring due to the influence of sensitive variables.

The Rules in Reconnecting the City Fabrics: A Morphological Study of the Regeneration Case
Authors: Zhai Y. 
Published: December 2019

AbstractIn the recent 30 years, Shanghai experienced fast urbanization which landscape shows various types of conflicts among the modern forms and the traditional forms. The insertion of new typologies in the traditional district introduces new urban characteristics and dynamics, which are not typically associated with the traditionally framed cities. The constructions of substantial industrial and commercial projects have caused the demolition of traditional urban forms. Urban designers aspire to revitalize the traditional neighborhood by combining urban fabrics without destroying the structure of the historic neighborhood. This paper attempts to exam the effectiveness of the urban network, the continuity of public structures and operational interactions between new projects and the local context through the study of a “failed” regeneration project in Shanghai, China. Consequently, this paper raised rules in reconnecting the city fabrics towards differential urbanism.

Authors: Nyein Nyein San Kyaw , Siridhara Siradol 
Published: December 2019

Abstract
Gap acceptance plays an important role in intersection design and signal warrant. This study investigates gap acceptance of drivers in Yangon, Myanmar. Three T-intersections were selected for study sites; two intersections in the urban area and the other one in Yangon suburb. As Yangon drivers drove on the right-hand side, the key movements that defined the intersection capacity would include left-turn from the major stream (LT-major), right-turn from the minor stream (RT-minor), and left-turn from the minor stream (LT-minor). Raff’s method was applied to determine the gap acceptance for these three conflicting movements. The result showed that the gap acceptance for LT-minor was the longest ranging between 7 to 15 seconds. The shortest gap acceptance belonged to the RT-minor for 4 to 8 seconds. The gap acceptance at urban sites was also shorter than that of suburban in all three movements. The drivers tended to decrease their gap acceptance when the traffic volume increased. However, the relationship between the gap acceptance and traffic flow was not significant.

Published: December 2019

Abstract
In order to study the influence of the preparation conditions on the performance of the polyvinylidene fluoride (PVDF) flat membranes, which were prepared via phase inversion method, a set of experiments based on response surface methodology (RSM) of central composite design (CCD) for three variables with five levels was performed. N,N-dimethyleacetamide (DMAc) and polyvinylpyrrolidone (PVP) were employed as solvent and pore former additive, respectively. PVDF and PVP conditions in the casting solution as well as the ethanol content in the coagulation bath were set as main manufacturing variables. Interactions of the preparation variables besides their quadratic main effects and on the desired responses namely; pure water flux, mean pore size, tensile strength, morphology and the porosity of the prepared membranes were investigated. The predicted and experimental results were found to be in good agreement (R2 values of 0.97, 0.95, 0.91 and 0.81 for pure water flux, mean pore size, tensile strength and porosity respectively, were obtained). The applicability of the CCD based RSM for the performance modeling of PVDF flat sheet membranes has been successfully evaluated.
Tribological properties of swollen nitrile rubber under dry and wet sliding conditions

Published: December 2019

Abstract
When nitrile rubber contacting with water under the external force during the service life, swelling and sliding wear occur. Since nitrile has similar polarity to water, the interaction between water and nitrile rubber and its influence on mechanical and tribological behaviors of the nitrile rubber play an important role in rubber performance, which is extremely necessary to be studied systematically. In this study, immersion experiments were conducted on three nitrile rubber samples which contained different acrylonitrile weight percentages of 18%, 26% and 41% (i.e. N18, N26, and N41) respectively. The hardness, tensile, dry and wet unidirectional sliding wear tests were further conducted. To reveal the mechanisms, the nuclear magnetic resonance (NMR) analysis and scanning electron microscopy (SEM) analysis were performed and interpreted accordingly. The results showed that cross-linking break based structural damage, substance dissolution and surface layer defects occurred after swelling, resulting in decreases in hardness and tensile strength and increases in permanent deformation fracture rates of the nitrile rubbers. The friction coefficient value of the un-swollen NBRs was positively related to the wear loss and decreased with the increase of the acrylonitrile content. During the wear process under dry conditions, the un-swollen rubbers presented hardening in aging while the swollen samples softened along with the deterioration of adhesive wear with higher steady-state friction coefficient value and wear loss. Under wet friction conditions, the susceptible wear behavior of the swollen rubbers induced reductions in friction coefficient and increases in wear loss. The swelling degree and its effects on mechanical and tribological behavior decreased with the increase of the acrylonitrile content. The swelling influences on the tribological behavior of nitrile rubber affected and acted on the entire wear process.
Impact of a Comprehensive Antimicrobial Stewardship Program on Institutional Burden of Antimicrobial Resistance: A 14-Year Controlled Interrupted Time-series Study
Authors: Peragine Christine , Walker Sandra A N , Simor Andrew , Walker Scott E , Kiss Alexander , Leis Jerome A 
Published: December 2019

Abstract

Background
Antimicrobial resistance (AMR) constitutes an international public health threat widely believed to result from excessive antimicrobial use (AMU). Numerous authorities have recommended antimicrobial stewardship programs (ASPs) to curb the selection of AMR, but there is a lack of data confirming this benefit.

Methods
A controlled interrupted time-series study spanning 14 years was performed to assess impact of a comprehensive hospital-based ASP that included pharmacist-led audit and feedback on institutional AMR. Patient-level microbiologic and AMU data were obtained from October 2002 to September 2016. Poisson regression models were used to identify changes in the incidence and trend of hospital-acquired (HA) antibiotic-resistant organisms (AROs) and multidrug-resistant organisms (MDROs). Changes in community-acquired (CA)–ARO, CA-MDRO, and inpatient AMU were assessed as controls and process outcomes.

Results
Statistically significant shifts in AMU, HA-ARO, and HA-MDRO trends coinciding with ASP implementation were observed, corresponding with a 9% reduction in HA-ARO burden (incidence rate ratio [IRR], 0.91 [95% confidence interval {CI}, .83–.99]; P = .03) and a 13% reduction in HA-MDRO burden (IRR, 0.87 [95% CI, .73–1.04]; P = .13) in the intervention period. In contrast, CA-ARO and CA-MDRO incidence continued to rise, with 40% (IRR, 1.40 [95% CI, 1.28–1.54]; P &lt; .0001) and 68% (IRR, 1.68 [95% CI, 1.57–1.82]; P &lt; .0001) increases in burden found, respectively.

Conclusions
Implementation of a comprehensive ASP resulting in reduced AMU was associated with a significant reduction in institutional AMR, even though community AMR increased during the same period. These results confirm that ASPs play an important role in the fight against AMR.
Effects of Random Forest Parameters in the Selection of Biomarkers
Authors: Khaire Utkarsh Mahadeo , Dhanalakshmi R 
Published: December 2019

Abstract
A microarray dataset contains thousands of DNA spots covering almost every gene in the genome. Microarray-based gene expression helps with the diagnosis, prognosis and treatment of cancer. The nature of diseases frequently changes, which in turn generates a considerable volume of data. The main drawback of microarray data is the curse of dimensionality. It hinders useful information and leads to computational instability. The main objective of feature selection is to extract and remove insignificant and irrelevant features to determine the informative genes that cause cancer. Random forest is a well-suited classification algorithm for microarray data. To enhance the importance of the variables, we proposed out-of-bag (OOB) cases in every tree of the forest to count the number of votes for the exact class. The incorporation of random permutation in the variables of these OOB cases enables us to select the crucial features from high-dimensional microarray data. In this study, we analyze the effects of various random forest parameters on the selection procedure. ‘Variable drop fraction’ regulates the forest construction. The higher variable drop fraction value efficiently decreases the dimensionality of the microarray data. Forest built with 800 trees chooses fewer important features under any variable drop fraction value that reduces microarray data dimensionality.
Accelerated failure time models with log-concave errors
Authors: Liu Ruixuan , Yu Zhengfei 
Published: December 2019

Summary
We study accelerated failure time models in which the survivor function of the additive error term is log-concave. The log-concavity assumption covers large families of commonly used distributions and also represents the aging or wear-out phenomenon of the baseline duration. For right-censored failure time data, we construct semiparametric maximum likelihood estimates of the finite-dimensional parameter and establish the large sample properties. The shape restriction is incorporated via a nonparametric maximum likelihood estimator of the hazard function. Our approach guarantees the uniqueness of a global solution for the estimating equations and delivers semiparametric efficient estimates. Simulation studies and empirical applications demonstrate the usefulness of our method.

Published: December 2019

Abstract

Background
Slowness of walking is one of the very first signs of aging and is considered a marker for overall health that is strongly associated with mortality risk. In this study, we sought to disentangle the clinical drivers of the association between gait and mortality.

Methods
We included 4,490 participants of the Rotterdam Study who underwent a gait assessment between 2009 and 2015 and were followed-up for mortality until 2018. Gait was assessed with an electronic walkway and summarized into the domains Rhythm, Phases, Variability, Pace, Tandem, Turning, and Base of Support. Cox models adjusted for age, sex, and height were built and consecutively adjusted for six categories of health indicators (lifestyle, musculoskeletal, cardiovascular, pulmonary, metabolic, and neurological). Analyses were repeated in comorbidity-free individuals.

Results
Multiple gait domains were associated with an increased risk of mortality, including Pace (hazard ratio (HR) per SD worse gait, adjusted for other domains: 1.34 [1.19–1.50]), Rhythm (HR: 1.12 [1.02–1.23]) and Phases (HR: 1.12 [1.03–1.21]). Similarly, a 0.1 m/s decrease in gait speed was associated with a 1.21 (1.15–1.27) times higher hazard of mortality (HR fully adjusted: 1.14 [1.08–1.20]). In a comorbidity-free subsample, the HR per 0.1 m/s decrease in gait speed was 1.25 (1.09–1.44). Cause-specific mortality analyses revealed an association between gait speed and multiple causes of death.

Conclusions
Several gait domains were associated with mortality risk, including Pace which primarily represents gait speed. The association between gait speed and mortality persisted after an extensive adjustment for covariates, suggesting that gait is a marker for overall health.

Abstract

OBJECTIVES
Preclinical studies have suggested acute stiffening of the aorta following experimental thoracic endovascular aortic repair (TEVAR), resulting in acute elevated pulse pressure, hypertension and possibly heart failure. The aim of this study was to evaluate cardiac remodelling following TEVAR.

METHODS
From 2005 to 2018, 519 TEVAR procedures were performed at a single centre. Transthoracic echocardiography was performed pre- and post-TEVAR in 31 patients without previous replacement of the thoracic aorta. Patient characteristics, drug information, radiographic and follow-up data were evaluated. Aortic details were measured in multiplanar reconstruction.

RESULTS
Transthoracic echocardiography was performed 2 ± 2 years after TEVAR. At this time, patients received significantly more antihypertensive drugs compared to the pre-TEVAR intake (beta-blocker therapy: P = 0.037; calcium channel blocker: P = 0.022). Compared to pre-TEVAR, there was a significant reduction in the left ventricular ejection fraction (P = 0.008) and tricuspid annular plane systolic excursion (P = 0.013) post-TEVAR. A significant increase in the left ventricular mass was not detected in this study (P = 0.95). The mean distance of 163 ± 66 mm of the descending aorta was covered.

CONCLUSIONS
This study suggests negative cardiac remodelling with a decrease in the left and right ventricular function following TEVAR despite an increase in oral antihypertensive medication. The impact of stiffer endovascular grafts compared with the native aortic wall should be considered by endovascular specialists and manufacturers.
