Abstract

Objective
This study aimed to obtain suggestions for new organizational-level item pools that companies could utilize to accomplish management philosophy and mission statements in the context of survey and work environment improvements for the national Stress Check Program.

Methods
A qualitative study was conducted using unsupervised learning. A large amount of text data related to management philosophy and mission statements were collected, that is, management messages described on the websites of all companies listed on the Tokyo Stock Exchange. For the main analysis, topic modeling was performed on the nouns from the management messages using Latent Dirichlet Allocation (LDA) to build a model consisting of 10 latent topics, each represented by a group of the 10 most frequently reoccurring nouns. Each group of nouns was qualitatively summarized based on the topic model.

Results
In total, 22 524 nouns were extracted from the management messages of 3575 companies. A topic model consisting of 10 latent topics was constructed using the LDA. The suggestion for new item pools included new technologies, business plans/strategies, company shareholders, health/happiness/wealth, profits/sales, development of society, a sustainable society, safety and security, customer/consumer satisfaction, corporate social responsibility, fairness, transparency, and human rights.

Conclusion
The suggestions for potential item pools were derived from management philosophy and mission statement that are not covered in the existing survey. The suggestions could be useful for motivating employers to implement work environment improvement. Future studies need to make definite items and investigate whether they correlate to job stressors and mental health among workers.

ObjectiveTo understand factors associated with pain intensity responder status following nonsurgical hip osteoarthritis (OA) intervention, according to sex.MethodsData were from individuals with hip OA participating in the Danish Good Life With Osteoarthritis in Denmark 8‐week education and exercise program. The following factors were recorded at program entry: age; education; mental well‐being; comorbidities; body mass index; symptoms in hip, knee, and low back; and program‐specific factors including education sessions, former participant lectures, and supervised exercise sessions. Pain intensity was recorded at baseline and at month 3 (post‐program) on a 0–100‐mm visual analog scale. Response was defined as pain intensity improvement of ≥30% from baseline to post‐program. Logistic regression was used and conducted separately in male and female subjects.ResultsThe sample included 791 men and 2,253 women. Female subjects had a mean baseline pain score of 47.2 of 100 (95% confidence interval [95% CI] 46.4–48.1) and male subjects had a score of 41.7 (95% CI 40.3–43.1). By post‐program, the proportion of pain responders was 50.4% among women and 45.8% among men (difference P = 0.025). Among women, program‐specific factors (attending former participant lectures and more supervised exercise sessions) were positively associated with pain response, as were better mental well‐being and fewer comorbidities, while symptoms in other joints/sites were associated with a decreased likelihood of response. Among men, program‐specific factors were not associated with response, while better mental well‐being and fewer comorbidities were associated with being a responder.ConclusionFindings suggest that the influence of some factors on pain response differ for male and female subjects and point to a potential need for targeted approaches for men and women who may require different key messages/approaches from health care providers.

ObjectiveTo compare magnetic resonance imaging (MRI)–detected structural abnormalities in patients with symptomatic midfoot osteoarthritis (OA), patients with persistent midfoot pain, and asymptomatic controls, and to explore the association between MRI features, pain, and foot‐related disability.MethodsOne hundred seven adults consisting of 50 patients with symptomatic and radiographically confirmed midfoot OA, 22 adults with persistent midfoot pain but absence of radiographic OA, and 35 asymptomatic adults underwent 3T MRI of the midfoot and clinical assessment. MRIs were read for the presence and severity of abnormalities (bone marrow lesions [BMLs], subchondral cysts, osteophytes, joint space narrowing [JSN], effusion‐synovitis, tenosynovitis, and enthesopathy) using the Foot Osteoarthritis MRI Score. Pain and foot‐related disability were assessed with the Manchester Foot Pain and Disability Index.ResultsThe severity sum score of BMLs in the midfoot was greater in patients with midfoot pain and no signs of OA on radiography compared to controls (P = 0.007), with a pattern of involvement in the cuneiform–metatarsal joints similar to that in patients with midfoot OA. In univariable models, BMLs (ρ = 0.307), JSN (ρ = 0.423), and subchondral cysts (ρ = 0.302) were positively associated with pain (P < 0.01). In multivariable models, MRI abnormalities were not associated with pain and disability when adjusted for covariates.ConclusionIn individuals with persistent midfoot pain but no signs of OA on radiography, MRI findings suggested an underrecognized prevalence of OA, particularly in the second and third cuneiform–metatarsal joints, where BML patterns were consistent with previously recognized sites of elevated mechanical loading. Joint abnormalities were not strongly associated with pain or foot‐related disability.

AbstractCurrent noncontact human–machine interfaces (HMIs) either suffer from high power consumption, complex signal processing circuits, and algorithms, or cannot support multidimensional interaction. Here, a minimalist, low‐power, and multimodal noncontact interaction interface is realized by fusing the complementary information obtained from a microelectromechanical system (MEMS) humidity sensor and a triboelectric sensor. The humidity sensor composed of a two‐port aluminum nitride (AlN) bulk wave resonator operating in its length extensional mode and a layer of graphene oxide (GO) film with uniform and controllable thickness, possesses an ultra‐tiny form factor (200 × 400 µm2), high signal strength (Q = 1729.5), and low signal noise level (±0.31%RH), and is able to continuously and steadily interact with an approaching finger. Meanwhile, the facile triboelectric sensor made of two annular aluminum electrodes enables the interaction interface to rapidly recognize the multidirectional finger movements. By leveraging the resonant frequency changes of the humidity sensor and output voltage waveforms of the triboelectric sensor, the proposed interaction interface is successfully demonstrated as a game control interface to manipulate a car in virtual reality (VR) space and a password input interface to enter high‐security 3D passwords, indicating its great potential in diversified applications in the future Metaverse.

AbstractDiscovering and engineering new materials with fast oxygen surface exchange kinetics and robust long‐term stability is essential for the large‐scale, economically viable commercialization of solid oxide fuel cell (SOFC) technology. The perovskite catalyst material BaFe0.125Co0.125Zr0.75O3 (BFCZ75), predicted to be promising from recent density functional theory (DFT) calculations and unconventional due to its extremely high Zr content and low electronic conductivity, exhibits oxygen reduction reaction surface exchange rates on par with Ba0.5Sr0.5Co0.8Fe0.2O3 (BSCF) and excellent stability at typical operating temperatures. New composite electrodes are engineered by integrating BFCZ75 with commercial electrode materials La1–xSrxMnO3 (LSM) and La1–xSrxCoyFe1–yO3 (LSCF) and achieve high performance as measured by low area specific resistance (ASR) values, with the LSCF/BFCZ75 ASR values comparable to top performing noncomposite electrode materials such as SrCo0.8Sc0.2O3–δ, BaNb0.05Fe0.95O3–δ and BaCo0.7Fe0.22Y0.08O3–δ. The use of BFCZ75 as a composite with LSCF achieving low ASR values shows that BFCZ75 is highly active and can easily integrate into existing SOFC material supply chains, lowering the barrier for potential commercial application of new electrode materials. Finally, these findings point to a broader unexplored class of perovskite materials with high fractions of redox inactive species (e.g., Zr, Nb, and Ta) that may unlock new pathways to realizing improved commercial SOFCs.

AbstractA comprehensive physical and cup quality assessment of coffee (Coffea arabica L.) has not yet been conducted on Kafa Biosphere Reserve coffees. Hence, the influence of location, production systems, and processing methods on coffee bean physical and sensorial qualities were studied to identify the inherent qualities and suitable preparation methods for the improvement of bean physical and organoleptic qualities. In a three‐stage nested design, factors such as location (Gimbo, Gawata, and Decha districts), coffee production system (forest, semiforest, and garden), and processing method (wet, semiwet, and dry) were considered. Preliminary coffee quality assessment data were gathered from bean physical and cup quality analyses of coffee obtained from the combination of the three factors. An ANOVA was conducted on preliminary coffee quality data. The result of the ANOVA showed that location and production system effects were significant only on bean moisture content (P < .01) and acidity (P < .05), respectively. The processing effect had a significant effect on bean moisture (P < .01), odor (P < .001), raw (P < .01), and preliminary grade (P < .05). Better coffee quality was maintained in the dry coffee processing method within the recommended moisture content. Forest and semiforest coffees respond poorly in odor and overall raw coffee quality when treated with wet and semiwet processing methods. Hence, to attain a better quality of coffee, rather than proper harvesting procedures, more emphasis should be given to choosing proper processing methods. Further investigation that includes the effects of elevation gradient is recommended.

AbstractThe porous electrode under the rib area suffers from lower local oxygen concentration and more severe water flooding than that under the channel, which significantly affect the performance of proton exchange membrane fuel cells. To improve the oxygen concentration and water drainage under the rib, a series of novel flow fields with auxiliary channels equipped with through‐plane arrayed holes were manufactured by three‐dimensional (3D) metal printing, and the cell performance, ohmic resistance and pressure drop were experimentally and numerically studied, respectively. The novel fields were based on the sophisticated modification of traditional serpentine and parallel flow fields, that significantly improved the cell performance at high current density with an optimal number or length of the auxiliary channels, owing to the trade‐off between the electric resistance and mass transfer under the rib. This novel flow field design solved the trilemma of performance, pressure drop and manufacture feasibility through the implementation of 3D printing technology.

AbstractThis work develops the Polyolefin Active‐Ester Exchange (PACE) process to afford well‐defined polyolefin–polyvinyl block copolymers. α‐Diimine PdII‐catalyzed olefin polymerizations were investigated through in‐depth kinetic studies in comparison to an analog to establish the critical design that facilitates catalyst activation. Simple transformations lead to a diversity of functional groups forming polyolefin macroinitiators or macro‐mediators for various subsequent controlled polymerization techniques. Preparation of block copolymers with different architectures, molecular weights, and compositions was demonstrated with ring‐opening polymerization (ROP), nitroxide‐mediated polymerization (NMP), and photoiniferter reversible addition–fragmentation chain transfer (PI‐RAFT). The significant difference in the properties of polyolefin–polyacrylamide block copolymers was harnessed to carry out polymerization‐induced self‐assembly (PISA) and study the nanostructure behaviors.

Published: May 2022

AbstractThe route via the cross‐linking of hyperbranched prepolymers has potential advantage to construct low dielectric constant (low‐k) resins owing to the enhanced molecular free volume in hyperbranched structure. However, it is still a challenge to prepare hyperbranched resins with good film‐forming property and low‐k. In this paper, two hyperbranched polycarbosilanes with reactive benzocyclobutene groups were synthesized via hydrosilylation reaction to avoid the generation of SiO bonds for enabling the low polarity of chemical bonds. The spacing groups including phenyl or ethylene were incorporated into the hyperbranched structures, and the effect of the spacing groups on the physicochemical properties of hyperbranched polycarbosilane derived resins were investigated. The phenyl groups were found to effectively decrease the dielectric constant (k), while endowing the resins with good film forming ability and thermostability. The UV/thermally cured phenyl group resin owing to dual crosslinked structure, the patterns would not be deformed significantly during thermally cured process. Both hyperbranched polycarbosilane derived resins could be potential photoresists.

AbstractThis publication highlights the effect that different chain extenders (CEs) have on the structure–property relationships of soy‐based polyurethanes that have been exposed to hydrolytic degradation for 480 and 960 h at 80°C. Gel content, crosslinking densities, surface energy, atomic force microscopy, dielectric, and dynamic mechanics were used for monitored structural changes. Polyurethanes (PU) is composed of a structure with minor phase separation when a chain extender is not used, maintaining all properties over time. However, when a chain extender, butane‐1.4‐diol (BDO), ethane‐1.2‐diol (MEG) our (2‐hydroxypropoxy)‐propane‐2‐ol are added, it is noted that there is a more significant degradation in the flexible domains, modifying the fraction between the initial rigid (HS)/soft (SS) segment that makes the polymer stiff and brittle. The hydrolysis degradation generates new Fourier transform infrared bands relative to urea (1640 cm−1) and amide (1800 cm−1). The reduction in band intensity of the C=Ofree at 1730 cm−1, while increasing the intensity of C=Obonded at 1710 cm−1 indicated a higher phase separation degree. After 960 h the TgS decreased, while the TgH was practically unchanged. The higher polarization observed in the PUs with BDO and MEG samples indicates the increased phase separation resulting in hydrolytic degradation.
Multiagent coverage search based on Voronoi and sparse heteroscedastic Gaussian process
Authors: Xu Xiaoling , Meng Wei , Cai Qianqian , Fu Minyue 
Published: May 2022

AbstractThis work is concerned with multiagent cooperative and autonomous coverage search in an unknown environment. A novel Voronoi and sparse heteroscedastic Gaussian process (SHGP)‐based search method is proposed to improve the target search efficiency. By means of heteroscedastic Gaussian process (HGP), each agent can estimate the probability of target existence in given locations online according to the local probability map. Then, these local probability maps are fused together to obtain a posterior probability distribution for target prediction. Based on that, the agents' search paths within Voronoi cells will be adjusted adaptively online to make sure all the agents can search for targets more efficiently. A challenging issue then falls in the computational complexity of the HGP. To solve this problem, we propose an adaptive ranked‐set sampling algorithm based on the weighted sampling process and K‐means clustering algorithm. Theoretical analysis on the discrepancy of the kernel matrix between the original probability points and the sampling points is also given. Simulation results demonstrate that our proposed coverage search method can improve the performance of the area search compared with the existing Voronoi‐based one.

AbstractThe excitatory‐inhibitory imbalance hypothesis postulates dysregulation of the gamma‐aminobutyric acid (GABA) and glutamate (Glu) neurotransmitter systems as a common underlying deficit in individuals with autism spectrum disorders (ASD). Previous studies suggest an important role of these systems in the pathophysiology of ASD, including a study of our group reporting decreased glutamate concentrations in the pregenual anterior cingulate cortex (ACC) of adults with ASD. The aim of this study was to replicate our previous findings of impaired glutamate metabolism in ASD in a new sample and to additionally quantify GABA in the ACC and dorsolateral prefrontal cortex (dlPFC). Concentrations of GABA and glutamate‐glutamine (Glx; combined glutamate and glutamine signal) were quantified in the ACC and dlPFC of 43 adults with ASD and 43 neurotypical controls (NTC) by magnetic resonance spectroscopy (MRS). The ASD group showed increased absolute GABA concentrations and elevated GABA/creatine ratios in the left dlPFC compared to NTC, while no group differences were detected in the pregenual and dorsal ACC. Previous findings of altered Glx concentration in the pregenual ACC of the ASD group could not be replicated. Regarding Glx concentrations and Glx/creatine ratios, there were no significant differences in the dlPFC and ACC either. The study supports the hypothesis of an altered GABA and glutamate equilibrium, indicating an imbalance between excitatory and inhibitory metabolism in ASD patients. However, inconsistent results across studies and brain regions suggest a complex underlying phenomenon.Lay Summary
Adults of the autism spectrum exhibit elevated levels of the inhibitory neurotransmitter GABA in the left dorsolateral prefrontal cortex.
This finding supports the hypothesis of an imbalance between excitatory and inhibitory equilibrium in patients with autism spectrum disorders.

AbstractObjective: The current research aimed to compare clinical outcome measures of two National Eating Disorder (ED) Day Services at the Maudsley Hospital from before the COVID‐19 lockdown, when treatment was face to face, with after the lockdown when treatment moved online.Method: Clinical outcome measures collected as part of the admission and discharge process were compared from the beginning and end of treatment for patients treated either via face‐to‐face or online delivery. Twenty‐nine patients’ data were analyzed (89% of them female, 11% male, 89% from White ethnic backgrounds, 11% from BAME ethnic backgrounds and a mean age of 25.99 years). Additionally, the mean change in outcome measures was also compared between the two groups (pre‐lockdown face to face and during lockdown online).Results: Treatment delivered face to face led to significant improvements in body mass index (BMI) but not in Eating Disorder Examination Questionnaire (EDEQ) Global and Work and Social Adjustment Scale (WSAS) Total scores. In contrast, treatment delivered online led to significant improvements in EDEQ Global and WSAS Total scores but not in BMI. Neither one of the delivery modalities created significantly larger mean changes in any of the clinical outcome measures than the other.Conclusions: Both face‐to‐face and online delivery of eating disorder day treatment show some success. Suggested improvements for using online delivery of treatment include implementing additional support opportunities, adapting the online format to improve communication and commitment and using a hybrid model of specific face‐to‐face elements with some online treatment.
