Published: June 2022

BackgroundThis study aimed to investigate the neural substrates of processing depression emotion in premenstrual syndrome (PMS) and healthy subjects of college students using blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI).MethodsDuring BOLD-fMRI scanning, 13 PMS patients and 15 healthy controls (HC) performed a picture visual stimulation task during luteal and follicular phases, in which participants and HC were asked to see pictures containing depression and non-depression emotions. Simultaneously, self-rating depression scales (SDS) were employed to evaluate the emotional status of participants.ResultsCompared to HC, right inferior occipital gyrus, right middle occipital gyrus, right lingual gyrus, right fusiform gyrus, right inferior temporal gyrus, cerebelum_crus1_R, cerebelum_6_R, culmen, the cerebellum anterior lobe, tuber, and cerebellar tonsil of PMS patients showed enhanced activation. In contrast, sub-lobar, sub-gyral, extra-nuclear, right orbit part of superior frontal gyrus, right middle temporal gyrus, right orbit part of inferior frontal gyrus, limbic lobe, right insula, bilateral anterior and adjacent cingulate gyrus, bilateral caudate, caudate head, bilateral putamen, and left globus pallidus exhibited decreased activation.ConclusionThe findings indicate that abnormal functional regulation of brain regions such as occipital lobe and cerebellum leads to abnormal changes in emotional regulation, cognitive ability, and attention distribution in PMS patients, implying significant central pathogenesis.

BackgroundFear of childbirth (FOC) is one of the most common psychological symptoms among pregnant women and significantly relates to cesarean section, anxiety, and depression. However, it is not clear the prevalence and risk factors of FOC among Chinese pregnant women since the outbreak of the COVID-19 pandemic.AimsThe objective of this study was to examine the associations between coping styles, intolerance of uncertainty, and FOC.MethodFrom December 2021 to April 2022, a cross-sectional survey was conducted in two hospitals in China through convenient sampling. The cross-sectional survey was conducted among 969 pregnant women, which included the Childbirth Attitude Questionnaire (CAQ), Intolerance of Uncertainty Scale-12 (IUS-12), and Simplified Coping Style Questionnaire (SCSQ).ResultsThe total prevalence of FOC was 67.8%. The percentages of women with mild (a score of 28–39), moderate (40–51), and severe FOC (52–64) were 43.6, 20.2, and 4.0%, respectively. The regression results indicated that primiparas, unplanned pregnancy, few spousal support, intolerance of uncertainty, and negative coping styles were significant risk factors of FOC. Women who adopt positive coping strategies experienced a lower level of childbirth fear.ConclusionThese findings suggest that cultivating positive coping styles and obtaining sufficient childbirth information may be helpful for mothers' mental health. Regular screening assessment of perinatal psychological symptoms, such as the high level of intolerance of uncertainty and negative coping styles, should be adopted to reduce the risk of fear of childbirth.

Published: June 2022

Background:Preeclampsia (PE) is a common multi-system disorder in pregnancy and a major cause of maternal and perinatal morbidity and mortality globally. Copper is a crucial micronutrient for human health.MethodsA systematic review was performed according to Preferred Reporting Item for Systematic Reviews and Meta-analysis (PRISMA) guidelines to synthesize the best available evidence regarding the correlation between maternal copper levels and PE from women with different geographical and economic backgrounds.ResultsA total of 34 studies containing 2,471 women with PE and 2,888 healthy pregnant controls across 16 countries were included for research. All studies were systematically reviewed and assessed with the Newcastle-Ottawa Scale (NOS), The Agency of Healthcare for Research and Quality (AHRQ) assessment tools according to the study types. Globally, there was no significant difference in maternal serum copper levels between women with PE and control (Mean difference 5.46, 95% CI −9.63, 20.54). Sub-group analysis from geographical and economic perspectives revealed contrasting results. In conclusion, copper is associated with PE, but the levels of copper leading to increased risk of PE varied across regions and economic development.ConclusionsThe deranged maternal copper levels are correlated with risks of PE, but it presents variously across different geographical and economic contexts.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=306536.

Published: June 2022

IntroductionIliopsoas abscess with septicemia in the pediatric population is rare. Early diagnosis and effective management of this emergent disorder remain challenging for clinicians.Case PresentationA 14-year-old girl presented with right lateral and posterior hip pain and fever for 7 days before admission. Blood culture was positive forStaphylococcus aureus.Enhanced magnetic resonance imaging revealed abscesses located in the right iliopsoas muscle and on the surface deep to the fascia of the right sacroiliac joint that were 6.8 cm × 6.2 cm × 5.7 cm and 3.7 cm × 3.5 cm × 2.1 cm, respectively. A diagnosis of right iliopsoas abscesses with septicemia was made. The patient received intravenous antibiotics, underwent ultrasound-guided percutaneous catheter drainage, and recovered uneventfully. Medical literature regarding this issue published in the English language during the last two decades was reviewed.DiscussionPrimary synchronous psoas and iliacus muscle abscesses are rare and emergent disorders in the pediatric age group. The diagnosis is generally delayed owing to the deep anatomic location and nonspecific signs and symptoms. A comprehensive medical history, meticulous physical examination, and judicious use of imaging studies could establish a timely and accurate diagnosis. Surgeons should be aware of the occurrence of multiple abscesses. Prompt and adequate antibiotic therapy accompanied by a mini-invasive approach, such as ultrasound-guided, laparoscopic, or video-retroperitoneoscopic drainage of the infectious focus, if indicated and feasible, is important to achieve a good outcome in the management of iliopsoas abscess.

Published: June 2022

ObjectiveAlthough the randomized controlled trial (RCT) of the efficacy of hysteroscopic resection in women with uterine septum has not shown any significant correlation in recent research, motivation for deeper study remains insufficient. In this study, the objective was to determine pregnancy-related outcomes, along with adverse obstetric outcomes, following hysteroscopic resection and also to determine whether women with hysteroscopic resection bear the same outcomes as women with normal uterine cavities.Search MethodsFrom January 1995 to February 2022, a systematic literature review was conducted to identify all studies published concerning the gestation outcomes of women with and without hysteroscopic resection while comparing the gestation outcomes of women after hysteroscopic resection and with a normal uterine cavity. Our primary outcome was the live birth rate (LBR). The secondary outcomes were term delivery, preterm delivery, spontaneous miscarriage, malpresentation, cesarean section, and other adverse obstetric outcomes.Results22 studies were included in this meta-analysis. The control groups of 14 studies were treated women, and the control groups of the other 8 studies were patients bearing a normal uterine cavity. Hysteroscopic resection was related to a higher rate of term delivery (OR = 2.26, 95% CI, 1.26–4.05), and a lower rate of spontaneous abortion (OR = 0.50, 95% CI, 0.27–0.93), and a lower rate of malpresentation (OR = 0.31, 95% CI, 0.19–0.50). Nevertheless, in comparison with the normal uterus group, the rates of preterm birth, cesarean section, and postpartum hemorrhage after resection did not return to normal levels.ConclusionHysteroscopic resection can effectively reduce the risk of abortion and malpresentation in patients possessing a uterine septum while increasing the term delivery rate. Although well-designed RCTs should confirm our meta-analysis, it still bears recommending to patients
Numerical Parametric Study of Coda Wave Interferometry Sensitivity to Microcrack Change in a Multiple Scattering Medium

Published: June 2022

The expansion of cracks in 3D printing concrete materials may lead to structural failure, so it is essential to monitor crack propagation development. Coda wave interferometry (CWI) has been proven to be sensitive to microcracks, however, the evolution pattern of ultrasonic coda waves during crack growth is still not clear. This paper reports a numerical study of the sensitivity and feasibility of CWI for monitoring microcrack growth in heterogeneous materials. A two-phase concrete model, which contains microcracks with different angles and lengths, was developed using the finite element analysis software ABAQUS. The relative velocity change (Δv/v) and the decorrelation coefficient (Kd) at different crack increments were quantitatively analyzed. The numerical simulation results show that coda waves are sensitive to microcrack length as well as the crack angle. The Δv/v increases linearly with the increase of the length of a single microcrack, and the Kd could be linked to the crack length quadratically. Furthermore, a quantitative functional relationship between the CWI observations (Kd, Δv/v) and the angle of the crack to the source/receiver and the relative length growth of the crack are established. In addition, the nonlinear relationship between slope and angle can be fitted with a sinusoidal function. The reported results quantitatively assess the coda wave variation pattern during crack propagation, which is important for the promotion and application of CWI technology.
Root-Zone Heat Priming Effects on Maximum Quantum Efficiency of PSII, Productivity, Root Morphology and Nutritional Quality of Two Aeroponically Grown Leafy Greens in a Tropical Greenhouse
Authors: He Jie , Tan Cassander , Qin Lin 
Published: June 2022

This study investigated the effects of root zone (RZ) heat priming on Eruca sativa (cv. Arugula) and Lactuca sativa (cv. Canasta) in a tropical greenhouse by exposing them to three different RZ temperatures (RZTs). For the first group, plants were grown at 25 °C-RZT for 36 days. The second group of plants was grown at 25 °C-RZT for 10 days before transferring to 38 °C-RZT for 10 days and then to 42 °C-RZT for another 16 days (primed). For the third group, plants were grown at 25 °C-RZT for 20 days and for the last 16 days were transferred to 42 °C-RZT (non-primed). RZ heat priming did not affect the leaf expansion of Arugula while the leaf expansion was slower in RZ heat primed Canasta compared to 25 °C-RZT plants. After transferring to 42 °C-RZT in the later stage, RZ heat primed Arugula had similar productivity but a larger root system with higher nutritional quality at harvest and during postharvest storage compared to those of 25 °C-RZT plants. After subjection to 42 °C-RZT, although RZ heat priming enhanced its nutritional quality, the productivity of Canasta was compromised. The results of this study suggest that it is feasible to enhance productivity and nutritional quality of leafy greens at lower production cost through RZT management.

Published: June 2022

Abstract
Micro, Small and Medium Enterprises (MSMEs) are a fundamental business pillar for the Indonesian economy. In MSMEs, capital is not the only problem that must be faced, but it must also be seen from the side of capital management to be considered so that business activities can run well and maximally. The problem found by researchers related to the Accounting Information System (AIS) in MSMEs is the decline in income in 2020 and 2021. One of the causes is the absence of correct accounting records. This study aims to determine the implementation of AIS in MSMEs and study the inhibiting aspects. The case study was conducted using descriptive qualitative research conducted at the Asira Food Store located in Wonomarto Village, North Kotabumi, North Lampung, Lampung. The result of this research is that Asira Food UMKM has not implemented an Accounting Information System.

Design of adaptive AC drive with adjustable dynamics

Published: June 2022

Ставится и решается задача проектирования адаптивного скоростного электропривода переменного тока с настраиваемой динамикой, построенного на базе вентильного двигателя с тиристорным преобразователем. При этом под настройкой динамики понимается настройка электропривода на технический оптимум с желаемым временем переходной характеристики. На практике такая настройка осуществляется с помощью адаптивного регулятора с эталонной моделью, коэффициенты которой зависят только от одного параметра – времени переходной характеристики (времени установления). Синтез закона управления для такого адаптивного регулятора выполнен в результате постановки и решения задачи о терминальном адаптивном управлении. Искомые параметры настройки адаптивного регулятора по построению являются коэффициентами эталонной модели и не зависят от параметров синхронной машины, на базе которой построен вентильный двигатель. Процедуры синтеза и моделирования реализованы в среде MATLAB & Simulink в виде программ и S-моделей. Результаты проектирования представлены в виде графиков переходных характеристик электроприводов с традиционным и адаптивным управлением. Показано, что адаптивный электропривод переменного тока обладает настраиваемым быстродействием с неизменным перерегулированием, которое соответствует критерию технического оптимума. При этом практически отсутствует влияние перекрёстных магнитных полей синхронной машины на динамику электропривода.
The problem of designing an adaptive speed-controlled AC electric drive with adjustable dynamics, built on the basis of a brushless motor with a thyristor converter, is posed and solved. At the same time, dynamics tuning is understood as the adjustment of the electric drive to the technical optimum with the desired transient response time. In practice, such adjustment is carried out using an adaptive controller with a reference model, the coefficients of which depend on only one parameter - the time of the transient response (setting time). The synthesis of the control law for such an adaptive controller was made as a result of setting and solving the problem of terminal adaptive control. By construction, the sought-for adaptive controller settings are the coefficients of the reference model and do not depend on the parameters of the synchronous machine on the basis of which the brushless motor is built. Synthesis and simulation procedures are implemented in the MATLAB & Simulink environment in the form of programs and S-models. The design results are presented in the form of graphs of transient characteristics of electric drives with traditional and adaptive control. It is shown that the AC adaptive electric drive has adjustable speed with constant overshoot, which corresponds to the technical optimum criterion. At the same time, there is practically no influence of cross magnetic fields of a synchronous machine on the dynamics of the electric drive.
