Objectives: The requirement of prolonged mechanical ventilation (PMV) is associated with increased medical care demand and expenses, high early and long-term mortality, and worse life quality. However, no study has assessed the prognostic factors associated with 1-year mortality among PMV patients, not less than 21 days after surgery. This study analyzed the predictors of 1-year mortality in patients requiring PMV in intensive care units (ICUs) after surgery. Design: Multicenter, retrospective cohort study Setting: ICUs at 5 tertiary hospitals in Beijing Participants: Patients who required PMV after surgery between January 2007 and June 2016 were enrolled. Interventions: None Measurements and Main Results: Of the 124 patients enrolled, the cumulative 1-year mortality was 74.2% (92/124). From the multivariable Cox proportional hazard analysis, cancer diagnosis (hazard ratio [HR] 2.14, 95% confidence interval [CI] 1.37-3.35; P<0.01), no tracheostomy (HR 2.01, 95% CI 1.22-3.30; P<0.01), enteral nutrition intolerance (HR 1.88, 95% CI 1.19-2.97; P=0.01), blood platelet count ≤150´10 9 /L (HR 1.77, 95% CI 1.14-2.75; P=0.01), requirement of vasopressors (HR 1.78, 95% CI 1.13-2.80; P=0.02), and renal replacement therapy (HR 1.71, 95% CI 1.01-2.91; P=0.047) on the 21 st day of mechanical ventilation were associated with shortened 1-year survival. Conclusions: For patients who required PMV after surgery, cancer diagnosis, no tracheostomy, enteral nutrition intolerance, blood platelet count ≤150´10 9 /L, vasopressor requirement, and renal replacement therapy on the 21 st day of mechanical ventilation were associated with shortened 1-year survival. The prognosis in PMV patients in ICUs can facilitate the decision-making process of physicians and patients’ family members on treatment schedule.

Published: October 2019

Background
Laparoscopic nephrectomy is a preferred technique for living kidney donation. However, positive-pressure pneumoperitoneum may have an unfavorable effect on the remaining kidney and other distant organs due to inflamed vascular endothelium and renal tubular cell injury in response to increased systemic inflammation. Early detection of vascular endothelial and renal tubular response is needed to prevent further kidney injury due to increased intraabdominal pressure induced by pneumoperitoneum. Transperitoneal laparoscopic living donor nephrectomy represented a human model of mild increasing intraabdominal pressure. This study aimed to assess the effect of increased intraabdominal pressure on vascular endothelium and renal tubular cells by comparing the effects of low and standard pressure pneumoperitoneum on vascular endothelial growth factor receptor-2 (VEGFR-2) expression and the shedding of syndecan-1 as the early markers to a systemic inflammation.
Methods
We conducted a prospective randomized study on 44 patients undergoing laparoscopic donor nephrectomy. Subjects were assigned to standard (12 mmHg) or low pressure (8 mmHg) groups. Baseline, intraoperative, and postoperative plasma interleukin-6, syndecan-1, and sVEGFR-2 were quantified by ELISA. Syndecan-1 and VEGFR-2 expression were assessed immunohistochemically in renal cortex tissue. Renal tubule and peritubular capillary ultrastructures were examined using electron microscopy. Perioperative hemodynamic changes, end-tidal CO2, serum creatinine, blood urea nitrogen, and urinary KIM-1 were recorded.
Results
The low pressure group showed lower intra- and postoperative heart rate, intraoperative plasma IL-6, sVEGFR-2 levels and plasma syndecan-1 than standard pressure group. Proximal tubule syndecan-1 expression was higher in the low pressure group. Proximal-distal tubules and peritubular capillary endothelium VEGFR-2 expression were lower in low pressure group. The low pressure group showed renal tubule and peritubular capillary ultrastructure with intact cell membranes, clear cell boundaries, and intact brush borders, while standard pressure group showed swollen nuclei, tenuous cell membrane, distant boundaries, vacuolizations, and detached brush borders.
Conclusion
The low pressure pneumoperitoneum attenuated the inflammatory response and resulted in reduction of syndecan-1 shedding and VEGFR-2 expression as the renal tubular and vascular endothelial proinflammatory markers to injury due to a systemic inflammation in laparoscopic nephrectomy.

PREDICTORS OF EMPLOYEE ENGAGEMENT IN MALAYSIA, AND THE MODERATING EFFECTS OF JOB DEMANDS AND TOTAL REWARD
Authors: Akmal Latiff Ayob  , Norzanah Mat Nor
Published: October 2019

As reported by Aon Hewitt in 2015 and 2017, there are still a lot of countries, including Malaysia, that recorded the employee engagement score below the global average value of 65%. Malaysia’s employee engagement score values were recorded at 61% and 59% for years 2015 and 2017, respectively. Low quality condition of new vehicles produced by Malaysia’s national automotive manufacturing companies is potentially caused by non-engaged employees. In academic literature, Job Demand-resource (JD-R) is the most widely used theory in employee engagement study. However, there are still a few gaps associated with the theory (i.e., inconsistence finding). In addressing the research gaps, this present study aims to examine whether job-related variables (i.e., job characteristics and job demands), personal-related variable (i.e., positive psychological capital), and environmental-organisational related variable (i.e., total reward) influence employee engagement. The relationships among the variables were explained using two selected theories, namely the JD-R theory, and Self Determination theory. This study makes several significant contributions to practitioners and theories especially on the employee engagement context. Generally, findings from the study significantly contributed knowledge to practitioners especially from Malaysia’s national automotive manufacturing companies on the major factors influencing employee engagement for them to understand, describe, and explain. In addition, for the theories, the study added to the general body of knowledge and current research work on the effects of job-related variables (i.e., job characteristics and job demands), personal-related variable (i.e., positive psychological capital), and organisational-environmental related variable (i.e., total reward) on employee engagement.

Published: October 2019

Timeliness of corporate annual financial reports is a crucial factor which affects the usefulness of information made available to external users especially investors. The purpose of this study is to examine the impact of corporate governance towards companies’ performances which consequently affect the timeliness of any report submitted to the local authority. This study takes the industrial product sector and the annual reports of companies operating therein and a list of submission dates of annual report to Bursa Malaysia by Malaysian public listed companies for data analysis. Regression analyses were performed to examine the relationship between corporate governance and company’s performance using return on asset (ROA) and return on equity (ROE) which will eventually affect the timeliness submission of the annual report to Bursa Malaysia. The Chief Executive Officer (CEO) duality and independent audit committee carry a significant relationship with timeliness of financial reporting whereas 8.8% of the studied companies submit early within the statutory requirement while the remaining 91.2% submit timely.
Development of a Test Apparatus for Estimation of Friction Parameters at Linear Pneumatic Cylinders
Authors: DAĞDELEN Mustafa , SARIGEÇİLİ Mehmet İlteriş
Published: October 2019

Pneumatic cylinders possess non-linear characteristics due to the air-compressibility and stick-slip in cylinder barrel. Friction characteristics in pneumatic cylinders is one of the main non-linearity that negatively affects the precise control. To be able to use these actuator systems in high level control applications, their friction force models should be developed. Hence, unknown friction parameters should be estimated correctly since the friction parameters of pneumatic cylinders are not listed in the manufacturers’ catalogue and these parameters cannot be calculated by only analytical methods. For that reason, in this study, a test apparatus is designed and experimental procedures are developed for the estimation of the friction parameters of linear pneumatic cylinders as in the form of static friction force, Coulomb friction force, Stribeck velocity and viscous damping coefficient.

Authors: ÇARDAK Fatma Seda
Published: October 2019

The requirement of housing due to the increase in population arising with the immigration allowance implied unplanned structuring. Remission of public improvements in our country which has frequently brought within law caused squatting and this situation brought shanty settlements along. These complex housing settlements negatively affected not only the owners living in but also the cities in their entirety. Yuregir, which is one of the central districts of Adana, is a district where the housings against license can be observed heavily nowadays due to the immigration receive. In this area, implementations of public housings are performed in stages by TOKI, Metropolitan Municipality of Adana and Yuregir District Municipality. These implementations are aligned as; Yavuzlar (Sinanpasa) TOKI Project which was finished in 2009, Kisla Neighborhood First Stage Urban Transformation TOKI Project which was finished in 2016 and Atakent Public Housing which was finished and handed over in 2018. In the context of this Work, the concept of urban transformation and the implemented public housing projects are examined in recognition of their physical, social and economic dimensions in the scale of Adana Yavuzlar Neighborhood. The findings achieved in consideration of the obtained data are explained in the “Conclusion” section.

Prediction of sediment transport rates in gravel-bed rivers using Gaussian process regression
Authors: Roushangar Kiyoumars , Shahnazi Saman
Published: October 2019

Estimating sediment transport rate in rivers has high importance due to the difficulties and costs associated with its measurement, which has drawn the attention of experts in water engineering. In this study, Gaussian process regression (GPR) is applied to predict the sediment transport rate for 19 gravel-bed rivers in the United States. To compare the performance of GPR, the support vector machine (SVM) as a common type of kernel-based models was developed. Model inputs of sediment transport were prepared based on two scenarios: the first scenario considers only hydraulic characteristics and the second scenario was formed using hydraulic and sediment properties. Obtained results revealed that the GPR models present better performance compared to the SVM models and other empirical sediment transport formulas. Also, it was found that incorporating the second scenario as input led to better predictions. In addition, performing sensitivity analysis showed that the ratio of average velocity to shear flow velocity is the most effective parameter in predicting the sediment transport rate of gravel-bed rivers.
The role of agent-based modeling and multi-agent systems in flood-based hydrological problems: a brief review
Authors: Simmonds Jose , Gómez Juan A. , Ledezma Agapito
Published: October 2019

Flood problems are complex phenomena with a direct relationship with the hydrological cycle; these are natural processes occurring in water systems, that interact at different spatial and temporal scales. In modeling the hydrological phenomena, traditional approaches, like physics-based mathematical equations and data-driven modeling (DDM) are used. Advances in hydroinformatics are helping to understand these physical processes, with improvements in the collection and analysis of hydrological data, information and communication technologies (ICT), and geographic information systems (GIS), offering opportunities for innovations in model implementation, to improve decision support for the response to societally important floods impacting our societies. This paper offers a brief review of agent-based models (ABMs) and multi-agent systems (MASs) methodologies' applications for solutions to flood problems, their management, assessment, and efforts for forecasting stream flow and flood events. Significant observations from this review include: (i) contributions of agent technologies, as a growing methodology in hydrology; (ii) limitations; (iii) capabilities of dealing with distributed and complex domains; and (iv), the capabilities of MAS as an increasingly accepted point of view applied to flood modeling, with examples presented to show the variety of system combinations that are practical on a specialized architectural level for developing and deploying sophisticated flood forecasting systems.

Authors: Nelson-Nuñez Jami , Walters Jeffrey P. , Charpentier Denisse
Published: October 2019

Many countries around the world now face the dual challenges of closing the remaining gaps in access to drinking water in rural areas while further addressing the issues of equity, quality, and sustainability outlined in the new Sustainable Development Goals (SDGs). Our research explores the key factors for sustainability in rural drinking water services in Chile, an important example not only due to its success in rural water access but also because of the new directions the country is taking to achieve the SDGs. Drawing on results from a Delphi study of Chilean rural water experts, we discuss the most important issues identified, including water availability and investment in community water organizations, as well as disagreement among experts, particularly around roles of private service providers and the national government. We leverage these results to assess Law No. 20.998 passed in 2017, which aims to address problematic variation in rural water services by introducing a stronger role for central government and conferring more responsibility on rural water organizations. The work presents insights for challenges countries closer to universal coverage will face as they work towards the SDGs and provides an analysis of the new rural drinking water governance landscape in Chile.

Authors: Kumar Vineeth A. , Ramkumar Mridula , Kanthlal S.K.
Published: October 2019

Background:

H+/K+ ATPase a protein present in the gastric parietal cells is a better target
for the prevention and treatment of gastric ulcer. Plant flavonoids have been reported to elicit
anti-ulcer activity by inhibiting the proton pump as well as by antioxidant defense mechanism.

Methods:

Chloroform fraction of hydro-alcoholic extract of passion fruit was screened for proton
pump inhibitory assay using goat parietal cell. In-silico computational docking studies were carried
out using Glide program in order to validate the inhibitory action of selected constituents.

Results:

The flavonoid rich fruit possess a promising radical scavenging activity against DPPH.
10.41μg/mL is sufficient to inhibit 50% of ATPase enzyme activity. A synergistic activity was also
achieved by the fruit with sub-effective doses of lansoprazole. Fenton's oxidation induced by H2O2
was also blunted by the fruit extract.

Conclusion:

The in-vitro and in-silico findings indicated that, passion fruit can be a good dietary
supplement for the prevention and management of ulcer.

Developing Embodied Conversational Agents for Coaching People in a Healthy Lifestyle: Scoping Review
Authors: Kramer Lean L , ter Stal Silke , Mulder Bob C , de Vet Emely , van Velsen Lex
Published: October 2019

Background

Embodied conversational agents (ECAs) are animated computer characters that simulate face-to-face counseling. Owing to their capacity to establish and maintain an empathic relationship, they are deemed to be a promising tool for starting and maintaining a healthy lifestyle.

Objective

This review aimed to identify the current practices in designing and evaluating ECAs for coaching people in a healthy lifestyle and provide an overview of their efficacy (on behavioral, knowledge, and motivational parameters) and use (on usability, usage, and user satisfaction parameters).

Methods

We used the Arksey and O’Malley framework to conduct a scoping review. PsycINFO, Medical Literature Analysis and Retrieval System Online, and Scopus were searched with a combination of terms related to ECA and lifestyle. Initially, 1789 unique studies were identified; 20 studies were included.

Results

Most often, ECAs targeted physical activity (n=16) and had the appearance of a middle-aged African American woman (n=13). Multiple behavior change techniques (median=3) and theories or principles (median=3) were applied, but their interpretation and application were usually not reported. ECAs seemed to be designed for the end user rather than with the end user. Stakeholders were usually not involved. A total of 7 out of 15 studies reported better efficacy outcomes for the intervention group, and 5 out of 8 studies reported better use-related outcomes, as compared with the control group.

Conclusions

ECAs are a promising tool for persuasive communication in the health domain. This review provided valuable insights into the current developmental processes, and it recommends the use of human-centered, stakeholder-inclusive design approaches, along with reporting on the design activities in a systematic and comprehensive manner. The gaps in knowledge were identified on the working mechanisms of intervention components and the right timing and frequency of coaching.

Abstract — Compressive Sensing is a method that is widely applied to signal processing. The ability and superiority of this method is able to reconstruct signals with limited input. This paper aims to use the Compressive Sensing method in processing discrete time signals. The advantage of this CS method is to provide an original signal estimate from a small number of incoherent linear measurements by utilizing the sparsity properties. Solution using the Compressive Sensing method uses the signal approach as a linear combination of the basic functions which are sparse matrices. Signal recovery is done by minimizing L1-norm of the system equation. This paper shows that with the method applied to signal processing, a limited number of measurement signals can be returned close to the original signal. With the difference between the recovery signal and the original signal which is quite small.

Screen House Test of Eight Biopesticide Formulation Bacillus subtilis against Downy Mildew, Peronosclerospora philipinensis, on Corn Plant. Corn downy mildew (DM) caused by Peronosclerospora spp. is a major constraint to the decline in maize production because it can cause yield loss up to 100%. So far, DM was successfully controlled with metalxyl fungicide. But lately, the effectiveness of this fungicide has begun to decline, so there is a need for an appropriate and environmentally friendly control alternative, one of which is the use of biological control agents. The aim of this study was to know the influence of eight types of biopesticide formulation of Bacillus subtilis in controlling DM of corn plant. The study was conducted at the screenhouse of the Indonesian Cereals Research Institute at Maros from November to December 2016. The treatments were arranged in a randomized block design with nine treatments and three replications. The treatment consisted of seed treatment with eight types of B. subtilis formulations (TM4, TM3, BNt4, BNt5, BNt6, BNt8, BJ6, and TLB1) and one treatment with sterile water (control). The variety used was Anoman which is known to be highly susceptible to DM. The variables observed included number of germination, the incidence and incubation period of disease, plant height, and dry weight of the plant. The results showed that the eight B. subtilis formulations had the potential to suppress DM in corn. The symptom of DM began to be seen at 18 days after planting (DAP) on the treatment of BNt8, while the controls have been seen at 12 HST. B. subtilis TM formulation has the highest potential to suppress DM with the percentage of disease suppression reaching 63.1%.

Exploration and Selection of Rhizobacteria that Inhibit Phytophthora capsici in vitro. Phytophthora capsici, a seed borne and the soil borne fungal pathogen is the cause of phytophthora blight on chili. The disease is difficult to control because of the resistant varieties unavailability in Indonesia. The aimed was to obtain isolates of rhizobacteria which has the ability to inhibit P. capsici in vitro. Rhizobacteria exploration was conducted in the chili production center in East Java (Malang, Batu, and Kediri) and West Java (Bogor). In one location, chili plant that had symptoms of phytophthora blight disease and a healthy plant next to it were chosen as samples to isolate P. capsici and the rhizobacteria. The rhizobacteria were isolated on NA, TSA, and TSAP (TSA with heated sample). Samples of diseased plants were used in isolation of P. capsici on V8 agar. The inhibition and compatibility of the rhizobacteria to inhibit P. capsici in vitro were tested by dual culture method. In this experiment, it was obtained 252 isolates of rhizobacteria and one isolate of P. capsici. Isolates of rhizobacteria with high to medium inhibition were E1, E3C2, and F2B1 respectively. All three isolates were then combined and tested against P. capsici in vitro. The highest inhibition was indicated by four isolate and combination of isolates, which were E1 isolate (58%), the combination of E1 + E3C2 isolates (58%), E1 + F2B1 (60%) and E1 + E3C2 + F2B1 (58 %).

Incidence dynamic of pod rot disease of cocoa clones in Lampung, Indonesia. The declining of production and productivity of cocoa in Indonesia might due to pests and diseases attacks and planting unselected clones. Dynamic of pod rot incidence was important to plan pest controlling. To study dynamic incidence of some cocoa clones, a research was conducting in Pesawaran District, a centre of cocoa production in Lampung. A farmer cocoa plot under agro-forestry system was selected which had been upgrading in 2014 by pruning and side-grafting with national clones including Sul 1, MCC 1, MCC 2, ICCRI 7 and selected local clone named T1, T2, and T3. The results showed that pod rot incidence occurred along the year of observation. For immature pod, pod rot incidence was dynamic and varied among months and clones. There was high pod rot incidence every months for particular clone. National clone Sul1 and local clone T3 exhibited more tolerant to pod rot disease than other clones. Clones Sul1 and T3 also produced more pod than others. High incidence of pod rot occurred on fruit stage of cherelle (incidence 38.7%) and small pod (incidence 18.8%) that well known as cherelle wilt symptom.

Detection and Transmission of  rice stunt virus on Ciherang and Situ Bagendit Varieties. The explosion of brown planthoppers recently has caused reduction of rice production in Indonesia. Brown planthoppers do not only act as pest, but also transmit Rice grassy stunt virus (RGSV) and Rice ragged stunt virus (RRSV). Detection of the existence of the two viruses in rice plants and vector insects is important to be done to ensure that the virus is infected with the vector. The aim of this research is to detect the existence of virus in varieties of Ciherang and Situ Bagendit as a result of transmission in the laboratory and to find out the ability of brown planthoppers to transmit stunt virus to both of the varieties. This research was compiled using Completely Randomized Design (CRD) with 4 treatments, namely healthy rice plants of Ciherang and Situ Bagendit varieties, Ciherang and Situ Bagendit varieties which were infested by brown planthoppers each with 5 repetitions. The parameters observed were incubation period, symptoms, plant height, number of leaves and incidence of disease. The data on plant height, number of leaves and incidence of disease were analyzed using ANOVA and continued with the Least Significant Difference (LSD) test at the level of 5%. The results showed that Ciherang and Situ Bagendit varieties were only positively infected by Rice ragged stunt virus. The results of the rice transmission showed that Ciherang variety had a faster incubation period of 10 DAI while Situ Bagendit was 14 DAI, but the two varieties showed an inhibition of growth in plant height and number of leaves compared to healthy plants with each incidence of 51.3% and 46.3%.
