The prediction of nitrogen not only assists in monitoring the nitrogen concentration in streams but also helps in optimizing the usage of fertilizers in agricultural fields. A precise prediction model guarantees the delivering of better-quality water for human use, as the operations of various water treatment plants depend on the concentration of nitrogen in streams. Considering the stochastic nature and the various hydrological variables upon which nitrogen concentration depends, a predictive model should be efficient enough to account for all the complexities of nature in the prediction of nitrogen concentration. For two decades, artificial neural networks (ANNs) and other models (such as autoregressive integrated moving average (ARIMA) model, hybrid model, etc.), used for predicting different complex hydrological parameters, have proved efficient and accurate up to a certain extent. In this review paper, such prediction models, created for predicting nitrogen concentration, are critically analyzed, comparing their accuracy and input variables. Moreover, future research works aiming to predict nitrogen using advanced techniques and more reliable and appropriate input variables are also discussed.

Authors: Lu Yingyu , Cao Bo , Hua Yidi , Ding Lei
Published: May 2020

Reasonably assessing the efficiency of green regional development is a key to improving environmental management and implementing sustainable development strategies. From the perspectives of environmental pollutant emissions, energy consumption, and production factor cost, the non-radial data envelopment analysis model based on the Malmquist index was applied to measure the green development efficiency and regional differences of 11 cities in Zhejiang from 2007 to 2016 from both static and dynamic aspects. This paper further analyzes the inherent influencing factors through the panel data model. The result shows: (1) The average static efficiency of green development in Zhejiang Province is 0.844. There is still 15.6% of improvement space from the frontier of production. Pollution emission management has the greatest improvement potential. Pure technical efficiency is the main factor restricting the static efficiency. (2) The dynamic efficiency of Zhejiang’s green development achieves an average annual rate of 0.26%, with a cumulative growth of 2.33%. The improvement of green development efficiency mainly depends on scale efficiency change. (3) The inherent factors affecting the efficiency of green development in the 11 cities mainly include three factors: the industrial structure, environmental regulation, and the urbanization level. The industrial structure has a positive effect, while environmental regulation and the urbanization level have negative effects. (4) The 11 cities are relatively evenly distributed in the four “static–dynamic efficiency” classification quadrants, and there is no "Matthew effect" of high–high, low–low polarization.
Narrowing the Gaps: Assessment of Logistics Firms’ Information Technology Flexibility for Sustainable Growth
Authors: Han Jeong Hugh , Wang Yingli , Naim Mohamed
Published: May 2020

In a supply chain management context, the effective management of Information Technology (IT) flexibility has been an issue to be resolved. However, no analytical method that calculates the required and actual level of IT flexibility dimensions has been proposed. This paper aims to provide an analytical tool that measures the required and actual levels of IT flexibility dimensions to provide the best value from a logistics firm’s IT flexibility. To do so, we propose a combined Importance‒Performance Analysis (IPA) and Partial Least Squared Structured Equation Modelling (PLS-SEM) method based on a multidimensional IT flexibility model. By comparing industry-level data with client firm data, our method allows for effective identification of a client logistics company’s multiple IT flexibility gaps and indicates where particular management interventions are required. By proposing importance and performance as measurement scales, our research suggests an analytical tool that managers can utilize to assess IT flexibility and identify any gaps that exist between actual and required flexibility levels. This allows managers to effectively address areas that demand further attention. This approach also leads to an improved understanding of how organisations can extract the best value from their investment in IT flexibility to contribute to sustainable growth.

Authors: Ren Jie , Luo Jar-Der , Rong Ke
Published: May 2020

When the resources of a focal organization are limited, strengthening the capability of sustainable performance by building up an ecosystem through cooperation is a good choice. When venture capital firms invest in sustainable projects, due to the non-rival and non-exclusive features of sustainable projects, venture capital firms that have built up the cooperation ecosystem can invite more investors to join the sustainable projects. This article analyzes what factors venture capital firms take into consideration when building relations to nurture sustainable investment ecosystems. The quadratic assignment procedure (QAP) method is used to explore how Chinese venture capital firms build up the syndication ecosystems. We conclude that very dominant venture capital firms like to cooperate with venture capital firms that have brokerage benefits and proper positions in the cluster to gain sustainable development. This article indicates that venture capital firms can build up syndication ecosystems by obtaining opportunities from indirect ties.

Authors: Carta Silvio , St. Loe Stephanie , Turchi Tommaso , Simon Joel
Published: May 2020

This paper presents and discusses an optimisation approach applied to spatial layouts in care home building design. With this study, we introduce a method for increasing the floor plan efficiency using a self-organising genetic algorithm, thus reducing energy consumption, improving the wellbeing of residents and having an implicit impact on the costs of energy and health care. In order to find an optimal spatial configuration, we elaborated and tested a number of design criteria based on existing literature reviews and interpreted through initial considerations of care home layouts. These are used as objectives in a Genetic Algorithm (GA) to evaluate the best design solution. The self-organised floor plan is then used to run a final simulation to observe how residents could use the optimised spaces and to measure the improved efficiency of the new plans. The paper concludes with the discussion of the results and some considerations for future studies and experiments using emergence behaviour models to improve sustainable development in design.
Building a Composite Indicator to Measure Environmental Sustainability Using Alternative Weighting Methods
Authors: Gómez-Limón José , Arriaza Manuel , Guerrero-Baena M.
Published: May 2020

Environmental sustainability in agriculture can be measured through the construction of composite indicators. However, this is a challenging task because these indexes are heavily dependent on how the individual base indicators are weighted. The main aim of this paper is to contribute to the existing literature regarding the robustness of subjective (based on experts’ opinions) weighting methods when constructing a composite indicator for measuring environmental sustainability at the farm level. In particular, the study analyzes two multi-criteria techniques, the analytic hierarchy process and the recently developed best-worst method, as well as the more straightforward point allocation method. These alternative methods have been implemented to empirically assess the environmental performance of irrigated olive farms in Spain. Data for this case study were collected from a panel of 22 experts and a survey of 99 farms. The results obtained suggest that there are no statistically significant differences in the weights of the individual base indicators derived from the three weighting methods considered. Moreover, the ranking of the sampled farms, in terms of their level of environmental sustainability measured through the composite indicators proposed, is not dependent on the use of the different weighting methods. Thus, the results support the robustness of the three weighting methods considered.
Reduction of Nitrogen Fertilizer Requirements and Nitrous Oxide Emissions Using Legume Cover Crops in a No-Tillage Sorghum Production System
Authors: Mahama G. Y. , Prasad P. V. V. , Roozeboom K. L. , Nippert J. B. , Rice C. W.
Published: May 2020

Nitrous oxide (N2O) emission from denitrification in agricultural soils often increases with nitrogen (N) fertilizer and soil nitrate (NO3−) concentrations. Our hypothesis is that legume cover crops can improve efficiency of N fertilizer and can decrease N2O emissions compared to non–cover crop systems. The objectives of this study were to (a) evaluate the performance of summer leguminous cover crops in terms of N uptake and carbon (C) accumulation following winter wheat and (b) to quantify the effects of summer leguminous cover crops and N fertilizer rates on N2O emissions and grain yield of the subsequent grain sorghum crop. Field experiments were conducted in the context of a wheat-sorghum rotation for two seasons in Kansas. Treatments consisted of double-cropped leguminous cover crops following winter wheat harvest with no fertilizer applied to the following grain sorghum or no cover crop after wheat harvest and N fertilizer rates applied to the grain sorghum. The cover crops were cowpea (Vigna unguiculata L. Walp.), pigeon pea (Cajanus cajan L. Millsp.), and sunn hemp (Crotalaria juncea L.). The three N treatments (were 0, 90, and 180 kg·N·ha−1). Fallow systems with 90 and 180 kg·N·ha−1 produced significantly greater N2O emissions compared with cropping systems that received no N fertilizer. Emissions of N2O were similar for various cover crops and fallow systems with 0 kg·N·ha−1. Among cover crops, pigeon pea and cowpea had greater C accumulation and N uptake than sunn hemp. Grain yield of sorghum following different cover crops was similar and significantly higher than fallow systems with 0 kg·N·ha−1. Although fallow systems with 90 and 180 kg·N·ha−1 produced maximum sorghum grain yields, N2O emissions per unit of grain yield decreased as the amount of N fertilizer was reduced. We conclude that including leguminous cover crops can decrease N fertilizer requirements for a subsequent sorghum crop, potentially reducing N2O emissions per unit grain yield and providing options for adaptation to and mitigation of climate change.

Study on the Spatial Pattern of an Extreme Heat Event by Remote Sensing: A Case Study of the 2013 Extreme Heat Event in the Yangtze River Delta, China
Authors: Wu Xiaohan , Xu Yongming , Chen Huijuan
Published: May 2020

The intensity and frequency of extreme heat events are increasing globally, which has a great impact on resident health, social life, and ecosystems. Detailed knowledge of the spatial heat pattern during extreme heat events is important for coping with heat disasters. This study aimed to monitor the characteristics of the spatial pattern during the 2013 heat wave in the Yangtze River Delta (YRD), China, based on the remote sensing estimated gridded air temperature (Ta). Based on the land surface temperature (Ts), normalized difference vegetation index (NDVI), built-up area, and elevation derived from multi-source satellite data, the daily maximum air temperature (Ta_max) during the heat wave was mapped by the random forest (RF) algorithm. Based on the remotely sensed Ta, heat intensity index (HII) was calculated to measure the spatial pattern of heat during this heat wave. Results indicated that most areas in the YRD suffered from extreme heat, and the heat pattern also exhibited obvious spatial heterogeneity. Cities located in the Taihu Plain and the Hangjiahu Plain generally had high HII values. The northern plain in the YRD showed relatively lower HII values, and mountains in the southern YRD showed the lowest HII values. Heat proportion index (HPI) was calculated to qualify the overall heat intensity of each city in the YRD. Wuxi, Changzhou, and Shanghai showed the highest HPI values, indicating that the overall heat intensities in these cities were higher than others. Yancheng, Zhoushan, and Anqing ranked last. This study provides a good reference for understanding the pattern of heat during heat waves in the YRD, which is valuable for heat wave disaster prevention.
Decolonizing Pathways to Sustainability: Lessons Learned from Three Inuit Communities in NunatuKavut, Canada
Authors: Hudson Amy , Vodden Kelly
Published: May 2020

Community led planning is necessary for Inuit to self-determine on their lands and to ensure the preservation of cultural landscapes and the sustainability of social-ecological systems that they are a part of. The sustainability efforts of three Inuit communities in Labrador during a Community Governance and Sustainability Initiative were guided by a decolonized and strength-based planning framework, including the values of Inuit in this study. This paper demonstrates that Inuit led planning efforts can strengthen community sustainability planning interests and potential. We situate the experiences of NunatuKavut Inuit within, and contribute to, the existing body of scholarly decolonization and sustainability literature. For many Indigenous people, including Inuit, decolonization is connected to inherent rights to self-determination. The findings suggest that decolonizing efforts must be understood and actualized within an Indigenous led research and sustainability planning paradigm that facilitates autonomous decision making and that is place based. Further, this study illustrates five predominant results regarding Inuit in planning for community sustainability that support sustainable self-determination. These include: inter and cross community sharing; identification of community strengths; strengthened community capacity; re-connection to community and culture; and the possibility for identification of sustainability goals to begin implementation through community led governance and planning processes.
Numerical Investigation for Periodic Orbits in the Hill Three-Body Problem
Authors: Kalantonis Vassilis S.
Published: May 2020

The current work performs a numerical study on periodic motions of the Hill three-body problem. In particular, by computing the stability of its basic planar families we determine vertical self-resonant (VSR) periodic orbits at which families of three-dimensional periodic orbits bifurcate. It is found that each VSR orbit generates two such families where the multiplicity and symmetry of their member orbits depend on certain property characteristics of the corresponding VSR orbit’s stability. We trace twenty four bifurcated families which are computed and continued up to their natural termination forming thus a manifold of three-dimensional solutions. These solutions are of special importance in the Sun-Earth-Satellite system since they may serve as reference orbits for observations or space mission design.

The health related problems are becoming more and more critical. This necessitates the need for continuous monitoring of health parameters of the patient. The health monitoring electronic equipment’s are not able to maintain health logs, analyzing the biomedical data obtained and assisting the patient and caregivers depending on the analysis. This project is intended to monitor the patient’s bio-signals like Electro Cardio Gram (ECG), pulse rate, respiration rate and temperature. Suitable algorithms can be used to find out the abnormalities in these bio-signals. Today Electronic Patient Records (EPR) are confined to the hospital database and are available within the hospital information system. This project also aims to a modification of Electronic Patient Records depending on the real-time vital parameter feed. These updated EPR information instead of storing in the hospital database are uploaded through the internet and stored in a cloud system. The patient need not have to carry the medical records in the form of papers, films or Compact Disc (CD) while moving from hospital to hospital. The patient needs to carry only an android mobile phone. Using the android application, the medical records stored in the cloud can be retrieved. The physician can analyze the medical records of the patient either through personal computers or through the mobile phones with the help of android application.

Beamforming Radiation Properties of Absorbing/Transparent Zones-Added Horn Antenna
Authors: TEBER Ahmet
Published: May 2020

In this study, we present beamforming of radiation patterns on a transmitter horn antenna by mounting an electromagnetic wave absorber, in which electromagnetic wave absorber is fabricated as concentric zones. The concentric zones consist of an absorbing material of manganese soft spinel ferrite blended with multi-walled carbon nanotubes with the thickness of 1 mm installed on the aperture of the antenna working in Ku-band. We have experimentally measured scattering parameter of transmission, S21, using a vector network analyser to perform radiation patterns in polar coordinates. As compared to the radiation properties of air horn antenna and absorbing/transparent zone-added horn antenna produces an appreciable effect to concentrate radiation beam in the main, side and back lobes with reducing side and back lobe levels for each frequency in H-plane. For the radiation pattern in E-plane, we have observed the suppressed side lobes at three frequencies of 15 GHz, 17 GHz and 18 GHz. The results indicate that the absorbing/transparent zone keeps an important role for further development of the applications of directional antennas so that the effective radiation is to be significantly concentrated.
An experimental investigation of the effect of thermophysical properties on time lag and decrement factor for building elements
Authors: OKTAY Hasan , YUMRUTAŞ Recep , ARGUNHAN Zeki
Published: May 2020

The time lag (TL) and decrement factor (DF) are essential for the heat storage capabilities of building elements, which strictly depend on the thermophysical properties of the elements. Many investigations are presented in literature arguing to find the influence of each thermophysical property on TL and DF by keeping the other properties constant. This study aims to investigate the effect of each property on TL and DF, utilizing relationships between the measurement values of the thermophysical properties of wall materials. Therefore, first, 132 new concrete wall samples were produced, and their thermophysical properties were tested. Secondly, TL and DF values for each building element are computed from the solution of the problem by Complex Finite Fourier Transform (CFFT) technique. Finally, a multivariate regression analysis has been performed, and the variations of each thermophysical property versus TL and DF are presented, and also the findings are compared with literature. The results show that each property alone (keeping the other properties constant) is not adequate to identify the thermal inertia and thermal performance of a wall element. Besides, 87.3 % decrease in thermal diffusivity corresponds to 6.03 h increase in the value of TL and 88.8 % decrease in value of DF; respectively, for W1 wall assembly.

Published: May 2020

Over the past decade, significant efforts have been made to improve the trade-off between speed and accuracy of surface normal estimators (SNEs). This paper introduces an accurate and ultrafast SNE for structured range data. The proposed approach computes surface normals by simply performing three filtering operations, namely, two image gradient filters (in horizontal and vertical directions, respectively) and a mean/median filter, on an inverse depth image or a disparity image. Despite the simplicity of the method, no similar method already exists in the literature. In our experiments, we created three large-scale synthetic datasets (easy, medium and hard) using 24 3-dimensional (3D) mesh models. Each mesh model is used to generate 1800--2500 pairs of 480x640 pixel depth images and the corresponding surface normal ground truth from different views. The average angular errors with respect to the easy, medium and hard datasets are 1.6 degrees, 5.6 degrees and 15.3 degrees, respectively. Our C++ and CUDA implementations achieve a processing speed of over 260 Hz and 21 kHz, respectively. Our proposed SNE achieves a better overall performance than all other existing computer vision-based SNEs. Our datasets and source code are publicly available at: sites.google.com/view/3f2n.

Authors: Nogueira Suelen Marçal , De Jesus Priscila Silva
Published: May 2020

Introdução: A violência sexual é um agravante de saúde pública e um problema mundial de caráter histórico e social que pode levar a inúmeras conseqüências à mulher. Entre todos os efeitos ocasionados pela violência sexual encontra-se a gravidez e os transtornos como a decisão de continuar ou não com a gestação de um filho do agressor. Objetivo: O estudo objetivou analisar os conceitos, os conflitos e os significados da violência sexual e do abortamento legal. Metodologia: Trata-se de uma pesquisa do tipo qualitativa e descritiva com análise bibliográfica de produções sobre a violência sexual e o abortamento como direito. Resultados e Discussão: A liberdade sexual aumentou a incidência de casos de violência sexual e paralelamente ocorreu o aumento do índice de abortamentos cometidos no mundo. Após a mulher ter passado pelo sofrimento do abuso sexual ela se depara com consequências físicas como os traumas genitais e extragenitais, Doenças Sexualmente Transmissíveis (DST’s) e ainda a gravidez indesejada. O aborto decorrente de estupro se enquadra em aborto eletivo previsto em lei como expõe o artigo 128 do Código Penal Brasileiro. Além das possíveis consequências físicas como infecção, hemorragia e esterilidade um aborto costuma provocar crises de arrependimento e culpa, com reações psicológicas, sociais e biológicas. Conclusão: A violência sexual atinge números alarmantes no Brasil e no Mundo e que o abortamento é um direito da vitima em casos de estupro, porém o ato pode gerar conflitos internos e somar maiores conseqüências às vitimas.

This work is part of the project “Determining factors in the reading habits of secondary school students. A study from the variables of the educational context” (PR2017040), funded by the Own Research Plan of the University of Cádiz. The main objective is to know the reading consumption of Spanish teenagers. Specifically, the consumption of analog reading of students of 1st year of Compulsory Secondary Education in Spain is studied. A sample of students from the province of Cádiz (n=664) and from other Spanish provinces (n=192) responded to a questionnaire about their reading habits. It allowed, in the first instance, to determine if informants enjoy reading and, later, to gather information about what and in what format they read, the criteria on which they are based to choose their readings, how much time they dedicate to read and where they get their readings. The results indicate that this sector of the population prefers reading adventure books, chooses books by subject, reads more during holidays and uses their own books. However, it is confirmed that the development of the reading habit is still a subject to pass.
The status quo and perspective for improvement of public works procurement performance in Vietnam
Authors: Nguyen Hai Luong , Watanabe Tsunemi
Published: May 2020

The public procurement sector plays a vital role in the economic development in developing countries such as Vietnam. However, public procurement activities usually perform poorly. This situation can be attributed to ineffective procedures and system (“hardware”) and human resource management (“software”), which occurs at every stage in project purchasing. The poor performance has reduced the effectiveness and efficiency of project delivery in the construction industry, causing delays, cost over-runs, and defects in construction projects. This paper, through working experience and observation by the first author, problems of public procurement were obtained as hypotheses and then validated based on questionnaire surveys and CIS (Construction Industry Structure) model analysis. The survey results indicated a relative correlation with CIS model in description of current construction industry. The study aims to identify issues of public procurement at all stages: pre bid, bid information, evaluation, and award. Based on identified major problems and determined risks, the results are expected to provide a valuable perspective, and thus, to propose necessary strategies to deliver high performance, competition and transparency for the public procurement. In further studies, it is relevant to propose a new model for sustainable public procurement based on the best value approach.
Price Based Environment of Design and Engineering Services

Design Services have not met the value and expectations of the clients and their project managers. A previous research project studied the impact of the price based award environment on construction practices, and this research proposes that designers’ current practices and expectations are also price based and not performance based asperceived by many due to the qualifications based system [QBS] approach. The authors also propose that the qualification-based system [QBS] is a price based system and should be replaced by a best value approach, which includes a best value selection process such as the Performance Information Procurement System (PIPS.) The proposed design model will give control and risk management capability back to designers by having the designers utilize expertise, create transparency utilizing a weekly risk report (WRR) and a risk management plan (RMP.) The new model utilizes the expert’s expertise to create transparency, giving the advantage to the higher performing professionals. The researchers interviewed over 400 professionals to validate the concepts of the best value approach for the design community.
The Mechanism of Linkages Between Online Community Participation and Festival Attendance: A Case Study of a Chinese Music Festival
Authors: Lei Weng Si (Clara) , (Claudia) Li Chun Chen
Published: May 2020

Online social network participation, and its impacts on festival attendees' motivation, have been investigated in previous studies. However, the results have been inconclusive. Social network participation motives have also been researched but have mostly been limited to Facebook and
other social media from the West. Social media participation motives in the East, for example in China, and its causes and effects on music festival attendance have remained underexplored. This study adopted a qualitative approach, using semistructured interviews and netnography to empirically
examine the connection between online social network participation and music festival attendance. Data collection included using netnography to explore a music festival social network chat group (online community) and then conducting in-depth interviews with festival attendees who were active
members of the online community. The study sheds new light on festival attendees' motives for online social network participation, a plausible mechanism and model to explain how an online music festival community sustains and connects its old and new members.
Effectiveness of Pre-operative Tranexamic Acid Administration Against the Amount of Bleeding During and After Open Reduction Internal Fixation (ORIF) in Closed Femur Fractures

Published: May 2020

ABSTRACT

Introduction. In femoral fractures case, bleeding often occurs and is accompanied by injury to other organs, so the possibility of impaired circulation (shock hemorrhagic) will be greater, especially at productive age. This study was aimed to evaluate the benefits of giving pre-operative tranexamic acid to sufferers of femur fractures accompanied by circulatory disorders and without circulation disorders in reducing peri-operative and postoperative bleeding ORIF.

Method. This study was a clinical experimental test with a cohort design at the Central Surgical Installation of Dr. Mohammad Hoessin Hospital Palembang. Samples were taken from patients who underwent ORIF Femur surgery, with a type of Hansen Winquist fracture type 0-2, which was pierced with tranexamic acid 10 mg / Kg BW.

Result. Intraoperative hemorrhage in ORIF in both treatment groups where patients with a history of preoperative shock had more amount of bleeding than the group who had no history of preoperative shock. Whereas from the amount of post-operative drainage, there were no significant differences in the two treatment groups.

Conclusion. The group of patients with a history of hemodynamic disorders (shock) given intravenous tranexamic acid, is useful in reducing intraoperative bleeding, but not significant to reduce postoperative bleeding in both treatment groups

Abstract

Introduction: Modified radical mastectomy (MRM) is a breast cancer treatment option that is still operable. One of the postoperative complications that can be found is the formation of seroma. High negative suction drain is done to treat seroma after surgery but it can contribute to increase the length of stay in hospital.

Methods: This study was a clinical randomized control trial (cRCT) conducted on 30 breast cancer patients in June - July 2019 at Moehammad Hoesin Hospital in Palembang. This study divided the two sample groups, each group consisting of 15 patients. One group was given half negative pressure on suction drain (experimental group) and the other used full negative pressure on suction drain (control group).

Results: There was a significant difference (p <0.005) between the full and half negative pressure groups where there were more seroma events in the full vacuum group in 9 (60%) cases and half vacuum in 2 (30%) but there were no significant differences in long period of stay (p> 0.005).

Conclusion: Half negative pressure is more effective in treating seroma than full negative pressure.
