Published: February 2022

A Company to reaching these targets requires human resources who have organizational citizenship behavior. The effect of perceived organizational support (POS), organizational culture, and work motivation on organizational citizenship behavior (OCB) of employees at PT Sokonindo Automobile is examined and analyzed in this study. This research was conducted on 104 employee respondents who were involved in several divisions. The research was conducted utilizing a quantitative analysis method with multiple linear regression equation analytical tools and the SPPS version 26 software. The research's empirical findings reveal that perceived organizational support (POS) has a positive and significant impact on PT Sokonindo Automobile employees' ability to build OCB. This effect is much langer and more significant than organizational culture and motivation, which also has a positive and significant influence on building OCB. The findings of this study imply the organizations that continue to provide support to their workers, have harmonious and friendly organizational culture will make employees more enthusiastic (motivated) at work and believe in the organization, which will make employees have high loyalty and voluntarily do work beyond the standard description work (OCB).

Published: February 2022

Objectives. To examine prescription opioid and nonopioid analgesic use among US construction workers and their associations with pain conditions and sociodemographic factors. Methods. We analyzed data for about 9000 (weighted 11.5 million per year) construction workers who responded to the Medical Expenditure Panel Survey from 2011 to 2018. We applied both descriptive statistics and multiple logistic regression procedures in the analyses. Results. An estimated 1.2 million (10.0%) of construction workers used prescription opioid analgesics annually. The adjusted odds of prescription opioid use were significantly higher for workers suffering from work-related injuries (adjusted odds ratio [AOR] = 3.82; 95% confidence interval [CI] = 2.72, 5.37), non‒work-related injuries (AOR = 3.37; 95% CI = 2.54, 4.46), and musculoskeletal disorders (AOR = 2.31; 95% CI = 1.80, 2.95) after we controlled for potential confounders. Adjusted odds of prescription opioid use were also higher among workers with poorer physical health (AOR = 1.95; 95% CI = 1.42, 2.69) or mental health disorders (AOR = 1.95; 95% CI = 1.41, 2.68). Conclusions. Work- and non‒work-related injuries and musculoskeletal disorders significantly increased prescription opioid use among construction workers. To prevent opioid use disorders, multipronged strategies should be approached. (Am J Public Health. 2022;112(S1):S77–S87. https://doi.org/10.2105/AJPH.2021.306510 )

Published: February 2022

Abstract
The ability to digitally count single molecules enables accurate and precise determination of the concentration of a disease biomarker. Owing to their intrinsic single-molecule sensitivity and fully electronic detection capability, solid-state nanopores show great promise for this task toward point-of-care diagnostic applications. Here, we describe the protocols for implementing a magnetic bead-based immunoassay strategy coupled with digital detection and downstream solid-state nanopore electrical readout. The digital scheme employs DNA nanostructures, as proxy labels for the presence (“1”) or absence (“0”) of the target protein. We provide step-by-step protocols for assembling and purifying DNA nanostructures; Preparing magnetic beads decorated with capture antibodies; Conjugating secondary detection antibodies to bind the DNA label; Functionalizing gold nanoparticles; and Running the full assay where thyroid stimulating hormone (TSH) from human serum samples is quantified down to the femtomolar range. The protocols and assay scheme presented herein are easily generalized to the quantification of a wide range of target proteins, by selecting the appropriate antibody pair.
Development of a kriging assessment framework and impact pathway for researching contamination with potentially toxic elements in urban landfill soil
Authors: Bakar Azizi Abu , Yoneda Minoru , Mahmood Noor Zalina 
Published: February 2022

Abstract
Landfill post-closure with contaminant concentration in soil below permissible limit assessed at limited spot does not represent the contamination issue. Therefore sizeable, qualitative, and cost-effective analysis of the concentrations of contaminants is needed and this work recommends kriging assessment and the logical impact pathway framework as factors of change in landfill aftercare management. The kriging framework is developed utilising lead (Pb) and chromium (Cr) data from inductively coupled plasma mass spectrometry (ICP-MS) analysis. The development of the kriging framework is conducted based on the observation of censored data from ICP-MS analysis. The estimation analysis involves the analysis of ordinary kriging with regression analysis, showing the interpolation of spatial correlation and regression error. Hence, ordinary kriging with regression of the variable of interest, i.e., Pb, using the data of the explanatory variable, i.e., Cr, is inappropriate. Further investigation with the utilisation of guess-field kriging analysis hypothetically exposed a potential contaminated area using an existing but limited number of explanatory variables; although, guess-field kriging may possibly result immense uncertainty at the area where the explanatory variable does not exist. Besides, this work anticipated outcomes in societal impact and sustainability practices from the proposed kriging framework by recommending a logical impact pathway. The development of the kriging framework and impact pathway reassure the necessary actions to be executed by responsible parties and act as the stimulus of a wider spectrum of improvement initiatives to oversee real issues, such as the time of occurrence, and to prevent negative impacts on the environment and humans.
How do trial teams plan for retention during the design stage of the trial? A scoping review protocol.
Authors: Murphy Ellen , Gillies Katie , Shiely Frances 
Published: February 2022

Abstract
Background Retention remains a major challenge for many clinical trials. The SPIRIT guidelines state the following information on retention should be included in the trial protocol “Plans to promote participant retention and complete follow up including list of any outcome data to be collected for participants who discontinue or deviate from intervention protocols”. This guidance shows the importance of planning retention methods and handling missing data as this can impact how the results of the trial are analysed and interpreted. The most recent Cochrane review of strategies to improve retention in clinical trials highlighted that some trials implemented multiple retention strategies and we questioned whether the use of multiple strategies was planned at the design stage and included in the protocol or are strategies implemented when retention becomes an issue within the trial. The purpose of our scoping review is to establish how trial teams prepare for retention at the design phase of clinical trials. Methods and analysis We will follow the methodological framework and guidelines for scoping reviews outlined by the Joanna Briggs Institute. We will search MEDLINE/PubMed, Scopus, EMBASE, CINAHL (EBSCO) and Web of Science. A comprehensive search strategy for PubMed was developed in collaboration with an experienced research librarian and the search will be adapted to each database. The screening process will involve two reviewers. EM will independently screen all titles, abstracts, and where necessary full protocol texts to determine eligibility. FS will screen 10% of the overall search output. We may purposively sample eligible protocols to ensure the protocols represent a variety of trial and intervention types. Next, data will be extracted from each protocol using the data extraction form. Once the data has been extracted the results will be synthesized. The analysis will be qualitative using a narrative summary and descriptive statistics where appropriate. DiscussionThe scoping review will help trial methodologists better understand when/if retention strategies are planned for during the design stage of the trial contributing to the PRioRiTy II unanswered question “How should people who run trial plan for retention during their funding application and creation of the trial (protocol development)?”.
A Case Study of Two Failures of a High Cut-slope in the Northeastern Area of Sichuan, China

Published: February 2022

Abstract
A high cut-slope in the northeast of Sichuan Province, China failed after excavation followed by rainfall. A second slope failure occurred under heavy rainfall a few days after being reinforced with anchor cables and grid beams. In this study, the detailed information and the failure history of the cut-slope were first presented. A series of numerical simulations were then conducted using finite element method (FEM) to analyze the slope stability and explore the failure mechanism. The numerical analyses found that the slope failures should not be simply attributed to rainfall. Other lessons have been learned from these two failures. They are: mis-characterization of the geological and hydraulic conditions of the site, poor understanding of the reaction of strongly weathered argillaceous shale materials with weak interlayers to water, and failing to implement proper drainage system in the slope after placing shotcrete on the slope surface. These resulted in the wrong measures to protect the cut-slope and the improper remediation works to stabilize the failed slope. The bond section of the anchor cable should be installed in the moderately weathered rock layer rather than strongly weathered layer with weak planes. The multiple failures of the slope warned all the parties that proper understanding of the geological and hydrological conditions of the site and the material properties is the starting point of any design and construction works.

Abstract
A study was conducted to investigate the effects of free-range, part-time free range, and confinement rearing systems on growth performance and slaughter traits in Lakha, Mushki, Peshawari, and Sindhi Aseel for 10-week duration (7-16 week). In total, 216 Aseel cockerels (6-wk-old), 54 from each variety, were allotted to 12 experimental groups, in a 3 × 4 (rearing system × Aseel variety) factorial arrangement under a randomized complete block design, replicated 3 times with 6 birds in each. Final body weight, weight gain, folds of increase, and mortality parameters of growth performance and carcass yield, breast, thigh, drumstick, wing, liver, gizzard, and heart parameters of slaughter traits were evaluated. Data were analyzed by using 2-way ANOVA under factorial arrangement. The results indicated increased body weight gain, folds of increase, breast and drumstick in both confinement and part-time free range (P<0.05), whereas enhanced body weight, dressing, thigh, liver, and gizzard only in confinement rearing system. Among the Aseel varieties, Sindhi showed enhanced final body weight, weight gain, thigh and drumstick yields, whereas breast and gizzard weights were found to be greater in Lakha and Sindhi. Carcass yield, however, remained higher in all varieties except Peshawari. In conclusion, indoor rearing system had positive effects on growth and carcass-related parameters. Among the varieties, Sindhi showed better growth and slaughter-related performance traits in alternative rearing systems and hence, can be used as slower growing meat chicken in the aforesaid systems of poultry production in developing countries for better livelihood.

Published: February 2022

Abstract
In this paper, the concept of photonic crystals (PhCs) is fundamental to the design and simulation of an all-optical device. The proposed logic device is composed of two-dimensional (2D) photonic crystal waveguides with a central photonic crystal ring resonator (PCRR). The new all-optical NAND logic gate is composed of two linear waveguides coupled to each other through a single compact PCRR. The plane wave expansion (PWE) and finite-difference time-domain (FDTD) methods are used to analyze the behavior of the structure that is implemented on the operational wavelength of 1700 nm on an air wafer of only 12 µm × 12 µm. The simulation results show that the proposed all-optical NAND gate is a strong candidate to be used for ultrafast photonic integrated circuits (PICs) being highly advantageous with high transmitting power, simple design and without use of the optical amplifiers and nonlinear materials.

Abstract
Nanocrystalline (NC) metals are attractive due to their outstanding mechanical, physical and chemical properties. However, they are generally metastable and prone to undergo grain coarsening, which severely impedes their engineering application, particularly at elevated temperatures. A strategy to counteract this phenomenon lies in decreasing the energetic driving force for grain growth, through grain boundary segregation according to the Gibbs adsorption isotherm. The natural thought of ‘more segregation is better’, which was exercised over decades to solve this problem, however, does not work because interfaces themselves are thermodynamic entities, with only limited solute decoration tolerance. Herein, we propose to solve this long-standing problem via introducing multi-component co-segregated interfaces. This concept allows us to maximize the solute decoration of interfaces and minimize their energy, without triggering formation of new phases. This is enabled by extending the high entropy alloy (HEA) concept from the bulk to interfaces, a strategy we refer to as interfaces with higher entropy. This design concept is not transferred one-to-one but constrained by a few rules that reflect the nature of interfaces: use of several co-segregating elements with high mixing entropy; segregation remains in the dilute limit; and use of elements with high segregation coefficient. The latter criterion marks an important difference to the HEA concept as a high segregation coefficient guarantees that alloying elements are deposited only to those locations where they are needed, namely, to the interfaces, thus drastically reducing alloying costs. We applied this new design approach to NC-Nb and show that we can increase its stability from 873 to 1023 K with as little alloying as only 1 at.% of Ti, Ni, Co and Hf with equal fractions. The material maintains its nanocrystalline structure even after 2200 h at 973 K. This work thus offers a new paradigm for designing stable dilute NC materials for advanced engineering application.

Published: February 2022

Abstract
Persistent organic pollutants (POPs) such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) accumulate in the food chain due to their physical and chemical properties and adversely affect human health. For this reason, this study aimed to determine the PAH and PCB concentration levels in pollen and honey samples in urban and semi-urban areas and to evaluate the risk of cancer that may occur by ingestion in Bursa, Turkey. The average total concentrations of 14 PAH (∑14PAH) compounds in pollen and honey samples were found to be 304.3±192.3 ng/g (average±standard deviation) and 650.2±118.1 ng/g for the urban area, and 329.6±160.6 ng/g and 464.3±66.4 ng/g for the semi-urban area, respectively. Similarly, ∑14PCB concentrations in pollen and honey samples were found to be 8.7±3.6 ng/g and 13.0±4.8 ng/g for the urban area, and 7.7±2.2 ng/g and 17.4±4.0 ng/g for the semi-urban area, respectively. It was determined that the pollen and honey samples in both sampling areas were affected by local PCB sources. Finally, while there was no cancer risk for PCBs due to ingestion of honey and pollen in both sampling areas, acceptable cancer risk has been calculated for PAHs.
Inside Shan-Shui: A Case Study of Parametric Optimization Design based on Reception Aesthetics of Eastern Art
Authors: Zeng Shaoting 
Published: February 2022

Abstract
This paper explored the quantitative research methods of visual and aesthetic optimizing design through a parametric exhibition design case study, taking the eastern art (Chinese painting and Japanese Zen garden) as the source of aesthetic principles. It is difficult to optimize a visual problem because aesthetic qualities mostly involve subjective making decisions and intuitive judgments, in which there exist a huge design space with little restrictions. In our study, we firstly investigated the natural scientific essences behind the aesthetic problem, through literature review, to find out the principles of aesthetic quantitative computing: narrowing the scope of design space based on the figure-ground perception; constructing the optimization rule system through the medial axis transformation (MAT) model; defining the optimal objects by the dynamics analysis of Shannon information energy. And thus, we utilized the shape grammar exploring the figure design subspace and getting optimal seven foam sculptures, and in the ground design subspace exploration, applied the genetic algorithm conducting the multi-objective optimization and getting the optimal exhibition layout. Finally, we got the exhibition design with the essence of reception aesthetics of eastern art and implemented it.
