Authors: Zhao Min , Wang Lu
Published: February 2022

Nowadays, in the era of Internet of Things, there are many kinds of teaching resources and ways to inquire. However, there are many problems in the selection, allocation, and management of teaching resources, and there is insufficient utilization of resources. Through the management of curriculum allocation and teacher resource allocation of teaching resources, this paper knows that since 2005 to 2011, the number of college-level English excellent courses and municipal-level English excellent courses has increased greatly, but the number of national-level English excellent courses is small. In order to strengthen the allocation and management of English teaching resources, the number of national excellent courses should be increased. According to the comparison ratio between the number of students and the number of English teachers in a university, which is 152 : 1, the number of English teachers is small. Among the 67 English teachers, senior titles accounted for 29.9%. Teachers with postgraduate degrees accounted for 22.4%. Ordinary teachers account for 47.7%. In order to improve the allocation of English teachers, ordinary teachers should be trained to improve the allocation of English teachers. By comparing 9-year-old teachers, 5-year-old teachers, and 1-year-old teachers, it is found that most teachers are more inclined to use teaching materials, teaching aids, and multimedia in choosing English teaching resources. And through the SMART teaching resource optimization model to the English teaching resources exist in the lack of funds, lack of administrators, school leaders do not pay attention to, and insufficient use of resources and other reasons for optimization. By comparing the SMART model with general English teaching, the UTAUT model and SICAS model, it can be seen that the model proposed in this paper has greatly improved students’ English school ability. Through the analysis of general English teaching and the SMART optimization model, UTAUT model, SICAS model precision, recall rate, F1, AUC, accuracy, and other performance, we know that the SMART model proposed in this paper has the best performance and has a good effect on the optimization of teaching resources in English teaching.

Authors: Han Chunxia , Wang Linjie
Published: February 2022

The pandemic of COVID-19 has posed a severe challenge to the traditional on-site centralized development projects; people therefore have to share data in a group by the cloud storage server and develop projects at home. The cloud server is untrustworthy, although it supplies the powerful computing capability and abundant storage space; so far wide research has been proposed to verify data integrity. Therefore, how to leverage the cloud server and ensure the integrity of the data (especially the encrypted data) stored on the remote cloud devices remains an issue for the clients. To address this issue, we utilize the technique of homomorphic hash function to implement reencryption ciphertext blocks and introduce a certificateless signature scheme for the integrity verification of encrypted data shared within a group. A detailed challenge-and-response game represents that the proposed scheme can preserve encrypted data blocks integrity against the internal/external attacker and malicious cloud service servers. We give the theoretical and experimental performance analysis of the scheme and exhibit that the scheme is efficient and practical.

Authors: Tang Xiang , Ma Jianxiao , Zhou Shun , Shan Tianci
Published: February 2022

With the increasingly significant trend of developing urban land for mixed-use, an increasing number of urban commercial and office complexes have been built. The parking demand characteristics of such buildings are more complex than the parking demand characteristics of single-use buildings due to more diverse influencing factors. As there are complicated linear and nonlinear relationships between parking demand and influencing factors, it is difficult to accurately predict parking demand using a single multiple regression analysis (MRA) model. Hence, in this paper, a combined algorithm based on the MRA model, beetle antennae search (BAS) algorithm, and BP neural network is proposed for demand prediction. In this paper, a two-level and ten-category index system is established and then mixed with the BP algorithm through the MRA model to improve the overall robustness and accuracy of the algorithm. Then, the BAS algorithm is used to search for optimal parameters involved in the BP neural network to avoid local optimization and improve the accuracy and efficiency of prediction. Finally, an instance analysis is carried out for verification, and the result indicates that the parking demand prediction accuracy of the MRA-BAS-BP algorithm is higher than the prediction accuracy of the traditional algorithm.

Published: February 2022

Walking, cycling, and feeder bus/tram for first- and last-mile (FLM) train access are often considered to have better health benefits, lower cost, and less environmental impacts than driving. However, little is known about the road safety impacts of these FLM access modes, particularly at a network level. This paper aims to investigate the impacts of train commuters’ access modes on road safety in Victoria, Australia. Macroscopic analyses of crash outcomes in each zone (i.e., Statistical Area Level 1) were performed using negative binomial (NB) and spatially lagged X negative binomial (SLXNB), accounting for potential indirect effects of mode shares in adjacent zones. This macroscopic analysis approach enabled the consideration of the safety effects across the network. The results showed that the SLXNB models outperformed the NB models. Commuting by train, either with walking or car as FLM access mode, was negatively associated with both total and severe crashes. In addition, commuting by train with feeder bus/tram access mode was negatively associated with severe crashes. Interestingly, commuting by train with cycling access mode was negatively associated with total crashes, with a larger effect when compared to walking and car access modes. Overall, the results suggested promoting active transport as FLM train access mode would lead to an improvement in road safety.
Time-Varying Research on Investors’ Trading Psychology Rational and Irrational Market Sentiment Based on the Perspective of 5G Networks and Information Economics
Authors: Yang Wenqi , Yang Chenzi , Yang Bing , Feng Guoqiang
Published: February 2022

Amid the ongoing rapid digitalization, consistent advancements in technologies such as 5G have become crucial. The demand for 5G technologies is expected to surge owing to the continued hybrid work culture, and 5G stock will emerge from the stocks of older tech and telecom companies. However, the COVID-19 epidemic continues to spread globally, causing a major impact on China’s macroeconomy and the stock market. It has a significant impact on the trading behavior of investors in 5G stock. Based on the framework of information economics and 5G Networks, we use the TVP-VAR model to empirically analyze the time-varying effects of rational and irrational market sentiment on investor herd behavior and overconfidence. The results show that rational market sentiment can always suppress herding behavior and overconfidence, while irrational market sentiment intensifies investors’ herd behavior most of the time, suppressing overconfidence in the short term and turning it into a positive effect in the medium term, and its long-term effects have almost disappeared. Compared with rational market sentiment, irrational market sentiment has a more direct and significant impact on herd behavior. The absolute values of the impulse responses of both market sentiments to the impact of overconfidence are relatively close. In addition, both market sentiments have typical characteristics of vulnerability to investor psychology. After the epidemic spread, both market sentiments accelerate the generation of overconfidence, while the positive impact on herd behavior gradually decreases. Our research shows that in the environment of information asymmetry, although investors will restrain their irrational conformity psychology, they still have not demonstrated their reasonable investment capabilities. Our conclusions will provide some references for government regulatory agencies and market investors under the background of the epidemic.

Published: February 2022

Objective. We aimed at exploring the role of let-7a in the pathogenesis of pediatric Henoch–Schönlein purpura (HSP) and its related mechanism. Methods. Fifty-five pediatric HSP patients and 20 paired healthy controls were included. The expressions of let-7a and TNFAIP3 were detected by RT-qPCR or/and western blot. Vessel fibrinoid necrosis was evaluated in skin tissues by PTAH staining. The serum IgA level was measured by ELISA. Cells were transfected with let-7a inhibitor and/or TNFAIP3 siRNA, accompanied by pretreatment with NF-κB inhibitor PDTC or not. After being cultured in HSP serum, the changes in cell viability, cell apoptosis, apoptosis-related proteins, and NF-κB pathway-related proteins were detected by CCK8, flow cytometry, and western blot. Results. The let-7a expression level was positively correlated with the serum IgA level and severity degree of vascular fibrinoid necrosis in HSP patients. Let-7a expression was significantly increased, whereas cell viability and TNFAIP3 expression were obviously decreased 48 h after HUVECs were incubated with HSP serum. Let-7a knockdown upregulated the cell viability, whereas it reduced the apoptotic ratio, apoptosis protein expressions (Bax/Bcl2 ratio, cleaved-caspase 3), and NF-κB pathway activation (reflected by reduced P65 nuclear translocation and p-IκBα expression) in HUVECs (all

. Besides, PDTC treatment remarkably diminished the anti-apoptosis effect of let-7a knockdown and pro-apoptosis effect of TNFAIP3 siRNA on HUVECs induced by HSP serum. Conclusions. Let-7a knockdown significantly suppressed vascular endothelial cell apoptosis induced by HSP serum by targeting TNFAPI3 via NF-κB signaling pathway. Our findings provided a potential therapeutic target for the treatment of HSP.

Authors: Sun Xuecheng , Li Shaotang , Lin Han
Published: February 2022

Objective. To investigate the interaction between LIMK1 and STK25 and its expression in colon cancer and its effect on the malignant evolution of colon cancer. Methods. Fluorescence quantitative PCR and immunohistochemistry were used to detect the expression of the LIMK1 gene in cancer and adjacent tissues of 20 clinical colon cancer samples. The overexpression plasmids of LIMK1 and STK25 were constructed. An shRNA specific to LIMK1 was synthesized and transfected into colon cancer cell lines. The expression levels of EMT-related markers in cell lines were detected by real-time PCR. The effects of LIMK1 and STK25 on the proliferation and invasion of colon cancer cell lines were detected by CCK-8 assay, Transwell, and clonogenesis. Results. LIMK1 interacted with STK25 and was highly expressed in colon cancer. High expression of LIMK1 and STK25 is associated with poor prognosis in colon cancer patients. LIMK silencing inhibits proliferation, invasion, and EMT of colon cancer. Cotransfection of LIMK1 and STK25 promotes the malignant progression and EMT of colon cancer. Conclusion. Protein interaction between LIMK1 and STK25 occurs. Overexpression of LIMK1 and STK25 plays a role in promoting cell proliferation and invasion in colon cancer tissues and cells. They also play a role in promoting the occurrence and development of colon cancer.

Published: February 2022

Purpose. The aim was to assess the cost-effectiveness of robotic arm-assisted total hip arthroplasty (rTHA) compared with manual total hip arthroplasty (mTHA) and to assess the influence of annual volume on the relative cost-effectiveness of rTHA. Methods. A database of both rTHA (n = 48 performed in a private centre) and mTHA (n = 512 performed in the National Health Service) was used. Patient demographics, preoperative Oxford hip score, forgotten joint score, EuroQol 5-dimensional 3-level (EQ-5D), and postoperative EQ-5D were recorded. Two models for incremental cost-effectiveness ratios using cost per quality-adjusted life year (QALY) for rTHA were calculated based on a unit performing 100 rTHAs per year: 10-year follow-up and a lifetime time horizon (remaining life expectancy of a 69-year-old patient). Results. When adjusting for confounding factors, rTHA was independently associated with a 0.091 (

p

) greater improvement in the EQ-5D compared to mTHA. This resulted in a 10-year time horizon cost per QALY for rTHA of £1,910 relative to mTHA, which increased to £2,349 per QALY when discounted (5%/year). When using the 10-year time horizon cost per QALY was approximately £3,000 for a centre undertaking 50 rTHAs per year and decreased to £1,000 for centre undertaking 200 rTHAs per year. Using a lifetime horizon, the incremental unadjusted cost per QALY gained was £980 and £1432 when discounted (5%/year) for rTHA compared with mTHA. Conclusions. Despite the increased cost associated with rTHA, it was a cost-effective intervention relative to mTHA due to the associated greater health-related quality of health gain, according to the EQ-5D outcome measure.

Authors: Wu Lianfeng , Zhang Chenchen
Published: February 2022

The thrombosis process is a multifactorial evolution process that includes many genetic and environmental factors that interact with each other. It refers to the existence of blood deposits in the heart or blood vessel walls or abnormal blood clots in the circulatory blood flow during the survival period of humans or animals for some reason. This article aims to analyze the research of blood vessel stenosis caused by arterial thrombosis of the lower extremities under the diagnosis of cardiac ultrasound based on the mobile information system. This article first introduces the mobile information nursing system and its development process. The mobile nursing information system has experienced three stages of development and is an important application of the further development of science and technology in medical information technology. It also proposes a medical diagnosis method based on SRM on a mobile platform and gives a technical roadmap for heart sound analysis and processing. Then, based on the mobile information system, the formation of arterial thrombosis in the lower extremities was analyzed and discussed in the ultrasound diagnosis of the heart, and the vascular stenosis caused by the arterial thrombosis of the lower extremities was analyzed by imaging. Experimental results show that when there is >50% stenosis or complete occlusion, the CTA false positive is more prominent, especially when the calf artery type is complete stenosis. The main cause is that the circulation of the lower limbs is very poor, the blood entering the blood vessels of the lower limbs is scarce, the capillaries are weakly enhanced, and the quality cannot be improved.

Published: February 2022

Background. Morbid obesity is frequently complicated by chronic liver diseases, including nonalcoholic fatty liver disease (NAFLD), nonalcoholic steatohepatitis (NASH), and fibrosis. Parathyroid hormone (PTH) is found to be elevated in morbid obesity due to the defective hepatic metabolism of vitamin D. Bariatric surgery is performed to help patients with BMI>40 kg/m2 to effectively lose weight, particularly in patients with obesity who are afflicted with complications such as NAFLD/NASH. Objective. This study aimed to evaluate the PTH level as a predictor of hepatic function in individuals with morbid obesity who have undergone bariatric surgery. Methods. Ninety subjects with morbid obesity referred for Roux en-Y gastric bypass surgery were recruited. After IRB approval, demographic profiles, anthropometric factors, liver biopsy, and laboratory tests were obtained. The two-dimensional shear wave elastography (2D-SWE) technique was applied to assess hepatic stiffness. Results. A significant reduction occurred six months after bariatric surgery in the anthropometric indices

Published: February 2022

COVID‐19 is a fatal disease caused by the SARS‐CoV‐2 virus that has caused around 5.3 Million deaths globally as of December 2021. The detection of this disease is a time taking process that have worsen the situation around the globe, and the disease has been identified as a world pandemic by the WHO. Deep learning‐based approaches are being widely used to diagnose the COVID‐19 cases, but the limitation of immensity in the publicly available dataset causes the problem of model over‐fitting. Modern artificial intelligence‐based techniques can be used to increase the dataset to avoid from the over‐fitting problem. This research work presents the use of various deep learning models along with the state‐of‐the‐art augmentation methods, namely, classical and generative adversarial network‐ (GAN‐) based data augmentation. Furthermore, four existing deep convolutional networks, namely, DenseNet‐121, InceptionV3, Xception, and ResNet101 have been used for the detection of the virus in X‐ray images after training on augmented dataset. Additionally, we have also proposed a novel convolutional neural network (QuNet) to improve the COVID‐19 detection. The comparative analysis of achieved results reflects that both QuNet and Xception achieved high accuracy with classical augmented dataset, whereas QuNet has also outperformed and delivered 90% detection accuracy with GAN‐based augmented dataset.

Published: February 2022

As a unique monitoring technique, electrostatic monitoring has been proved to be effective on prognostics and health management of tribological system by using electrostatic sensors. Wear-site sensor (WSS) with a flat circle probe and oil-line sensor (OLS) with a ring probe are two typical sensor types for electrostatic monitoring. However, this developing technique has not been applied in actual industry manufacture so far due to the united characteristics on electrostatic sensors. This paper first presents the mathematical models of both WSS and OLS for theoretical simulation. Then a series of contrast analysis on sensor characteristics between WSS and OLS with varied sensor structure parameters are presented. The results show that the distributions of spatial sensitivity for WSS or OLS itself only are similar, while they are quite different between WSS and OLS. Both WSS and OLS are symmetrical and their distributions can be simplified in one phase for further investigations. The theoretical efficiency curves have close relationship between WSS and OLS. The investigations of sensor performances on characteristics and a presented unified three level system have offered a better electrostatic sensor application in future.
Rare Case of Cavernous Haemangioma of the Right Atrium with Probable Hepatic Haemangioma
Authors: Harrison Sally
Published: February 2022

Cardiac haemangiomas are rare causes of atrial masses. This case report is of a 44-year-old male who presented with a right atrial mass that was found incidentally on a CT performed for renal colic. The mass was further investigated with a transthoracic echocardiogram that showed that it was echodense and arising from the Eustachian valve in the right atrium. Coronary angiogram revealed large well-developed atrial branches that crossed superiorly over the left atrium and entered the mass in the right atrium. Surgical resection was undertaken, and this confirmed that the mass had a fleshy, encapsulated appearance with a sessile stalk. Histology demonstrated a cavernous haemangioma. The patient had a residual small defect in the interatrial septum postoperatively but otherwise made a good recovery.

Authors: Xiao Xuehua , Gan Fengping , Yu Haixia
Published: February 2022

This study was aimed to discuss the feasibility of distinguishing benign and malignant breast tumors under the tomographic ultrasound imaging (TUI) of deep learning algorithm. The deep learning algorithm was used to segment the images, and 120 patients with breast tumor were included in this study, all of whom underwent routine ultrasound examinations. Subsequently, TUI was used to assist in guiding the positioning, and the light scattering tomography system was used to further measure the lesions. A deep learning model was established to process the imaging results, and the pathological test results were undertaken as the gold standard for the efficiency of different imaging methods to diagnose the breast tumors. The results showed that, among 120 patients with breast tumor, 56 were benign lesions and 64 were malignant lesions. The average total amount of hemoglobin (HBT) of malignant lesions was significantly higher than that of benign lesions (P < 0.05). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of TUI in the diagnosis of breast cancer were 90.4%, 75.6%, 81.4%, 84.7%, and 80.6%, respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of ultrasound in the diagnosis of breast cancer were 81.7%, 64.9%, 70.5%, 75.9%, and 80.6%, respectively. In addition, for suspected breast malignant lesions, the combined application of ultrasound and tomography can increase the diagnostic specificity to 82.1% and the accuracy to 83.8%. Based on the above results, it was concluded that TUI combined with ultrasound had a significant effect on benign and malignant diagnosis of breast cancer and can significantly improve the specificity and accuracy of diagnosis. It also reflected that deep learning technology had a good auxiliary role in the examination of diseases and was worth the promotion of clinical application.

Published: February 2022

To assess the diagnostic value of ultrasound Superb Microvascular Imaging (SMI) and versus Doppler ultrasound (TCD) for microvascular structure and aerodynamic changes in vertebral artery dissection (VAD). In this paper, we firstly simulate the process of clinician recognition of vertebral artery dissection and propose a combination of a priori shape information of vertebral artery dissection and deep folly convolutional networks (DFCNs) for IVUS. In this paper, 15 patients with vertebral artery dissection confirmed by SMI, digital subtraction angiography (DSA), or computed tomography angiography (CTA) from 2020 to 2021 were selected, and the true and false lumen diameters, peak systolic flow velocity (PSV), end-diastolic flow velocity (EDV) and PSV, EDV, and plasticity index (PI) of the intracranial vertebral artery were measured. Among the 15 patients with VAD, 4 (27%, 4/15) had trauma-induced secondary vertebral artery entrapment and 11 (73%, 11/15) had spontaneous entrapment without a clear cause. According to the structural characteristics of the vessels, there were 11 cases (73%, 11/15) of double-lumen, intramural hematoma, and vertebral artery dissection aneurysm, and 11 cases (73%, 11/15) of V1 segment. SMI not only provides an objective assessment of the vascular morphology and aerodynamic changes in VAD but also, in combination with TCD, can further determine the opening of the traffic branches in the posterior circulation, providing reliable information for the early diagnosis and treatment of microvascular dissection of the vertebral artery.

Authors: Neugebauer Juliane , Hagen Christina , Brockmann Christian , Juhl David , Schuster Sven Ole , Steppat Dagmar , Görg Siegfried , Ziemann Malte
Published: February 2022

Background and Objectives: In Germany, the donor history questionnaire (DHQ) is traditionally filled in at the donation center to avoid any influence of others. Since March 2020, it has been suggested to donors to answer the DHQ already at home and to call if they have any concerns to reduce the number of ineligible donors on-site during the COVID-19 pandemic. Materials and Methods: We evaluated the rate of ineligible donors before and after March 2020. Additionally, an anonymous online survey asking for the donors’ attitude towards the DHQ was performed. It included questions on whether and for what reason the DHQ had been answered incorrectly in the past. Results: The rate of ineligible donors decreased by 27% (from 7.1% to 5.2%). In total, 5,556 of 10,252 invited donors completed the survey (54.2%). 88.6% reported either going through the DHQ at home or knowing all questions from their previous donations. 444 donors (8.0%) had at least once postponed a donation after reading the DHQ at home. 68 donors (1.2%) admitted having intentionally provided false answers in the past (9 at home, 43 on-site, 14 both, 2 unknown). Not wanting to be rejected once arriving at the donation center was an important motivation for 42% of donors answering incorrectly on-site. Details on 46 incorrect answers were provided: only 17 had no influence on donor eligibility or product quality. In 5 cases, some blood products might have had impaired quality. Truthful answers to 17 questions would have led to deferral, mostly due to increased risk for unrecognized viral infections transmitted by sexual contacts. For a further 7 questions, there was insufficient information available to determine possible consequences. Asked about their general opinion, 753 (13.6%) of all donors estimated the risk of incorrect answers being greater on-site, while 239 (4.3%) presumed an increased risk at home. Conclusion: Answering the DHQ prior to a donation visit prevented ineligible donors from visiting the donation center. Furthermore, it might improve honesty, as the discomfort of being deferred after arriving at the donation center was an important reason to answer incorrectly. Overall, there was no increased risk of donor or product safety, and potentially even a benefit.

Published: February 2022

The aim of the work: based on the use of the program of multiparametric neural network clustering to analyze the results of examination and surgical treatment of patients with primary and postoperative ventral hernia in morbid obesity to identify a group of patients with high risk of complications in the postoperative period.

Materials and Methods. A comprehensive clinical-instrumental and laboratory examination of 237 patients with primary ventral and postoperative ventral hernia with concomitant morbid obesity with subsequent assessment of the nature of complications in the early and late postoperative periods was conducted. Patients were examined according to standards with this nosology, including general clinical, detailed study of all organs and systems of the body and local status (location, size, length of hernial protrusion) according to the EHS classification (2009). In the postoperative period, early (prolonged lymphorrhea, seroma, hematoma, infiltrate, marginal necrosis of the skin, suppuration) and late (mesh migration, meshomas, intestinal and ligature fistulas, mesh rejection, chronic pain, hernia recurrence) local and general (abdominal compartment syndrome, pulmonary embolism, pneumonia, myocardial infarction) complications. Clustering of subjects by groups using the add-on NeuroXL Classifier for Microsoft Excel was conducted for more in-depth analysis and in order to predict the complications in the postoperative period

Results and Discussion. Analysis of cluster pictures during neural clustering based on clinical and anamnestic data and types of surgical interventions revealed that in predicting the risk of complications in the postoperative period based on combined changes, the combination of sex, obesity II-III and respiratory failure when own tissue hernioplasty and Onlay in patients were the most important. It should also be noted that the identified pattern primarily relates to the development of complications such as acute cerebrovascular accident, seroma and marginal necrosis of the postoperative wound. The lowest complication rate was observed in obese patients during laparoscopic hernioplasty and eMILOS (mini/less open sublay).

Для них характерна наявність коморбідних станів (АГ, некомпенсованого ЦД 2 типу, МС, ХОЗЛ та таких факторів ризику ІХС, як дисліпідемія, куріння, вживання надмірних доз алкоголю та обтяжена спадковість).

Характерними рисами клінічного “портрету” хворого на ГКС (ІМ) з КІНК є тяжкий загальний стан хворого, який зумовлений наявністю комбінованого багатосудинного ураження вінцевих артерій (в 4,78 раза частіше, ніж при ізольованому ГКС) та більшим обʼємом міокардіального некрозу, ознаки гіпертрофії та ремоделювання з суттєвим зниженням систолічної (ФВ менше 50 %) та діастолічної функцій. Часта наявність життєво загрозливих ускладнень гострого періоду ІМ (порушень ритму і провідності та гострої серцевої недостатності визначали прогнозування високого ризику смертності за шкалою GRACE (172,7±12,7 бала)).

Мета роботи: проаналізувати досвід лікування хворих з ускладненими дивертикулами товстої кишки, в тому числі з використанням лапароскопії і ендоскопічної техніки для удосконалення та вибору належної діагностично-лікувальної тактики при даній патології.

Матеріали і методи. Проведено аналіз результатів лікування 121 хворого за період з 2008 до 2021 р. госпіталізованих ургентно при ускладненнях дивертикулярної хвороби, які виникли: товстокишкова кровотеча – у 60 хворих, дивертикуліт – у 9, перфорація дивертикула – у 19, дивертикулярний інфільтрат – у 18, а у 15 хворих було поєднання: дивертикуліт та дивертикулярний абсцес – у 6, дивертикуліт та перитоніт – у 4, дивертикуліт із динамічною кишковою непрохідністю – у 5. Хворим застосовували стандартний діагностично-лікувальний алгоритм.

Результати досліджень та їх обговорення. В групі хворих із клінікою товстокишкової кровотечі (60) при неефективності гемо­статичної терапії у 7 пацієнтів в ургентному порядку було виконано резекцію ураженого сегмента товстої кишки з кровоточивими дивертикулами в об’ємі лівобічної геміколектомії (6) та резекції сигмоподібної кишки (1) з формуванням анастомозу “кінець в кінець”. У групі хворих із запальними ускладненнями дивертикулярної хвороби неперфоративного генезу (42) розпочинали консерватине загальне та місцеве лікування. Прооперовано 6 хворих, у яких спостерігали прогресування інфільтрату та абсцедування: резекція сегмента товстої кишки з дивертикулярним абсцесом із виведенням кінцевої стоми. В групі з перфоративним дивертикулітом (19) всі хворі були в ургентному порядку прооперовані. Післяопераційної летальності не спостерігали. У хворих, яким застосовували лапароскопічні методи діагностики та лікування, післяопераційних ускладнень з боку післяопераційної рани не спостерігали.

Таким чином, найпоширенішими ускладненнями дивертикулярної хвороби є запальні ускладнення та кровотеча, лікування яких переважно консервативне. Лікувальна тактика при запальних ускладненнях дивертикулів диференційована: спочатку консервативна з місцевою протизапальною терапією, а при ускладненні перфорацією – хірургічна з можливим застосуванням малоінвазивних лапароскопічних методів лікування.
First record and description of female Onomarchus leuconotus (Serville, 1838) (Insect: Orthoptera: Tettigoniidae) from peninsular India

Published: February 2022

The members of family Tettigoniidae, commonly called katydids, generally exhibit mimicry and camouflage with shapes and colours similar to leaves. The genus Onomarchus Stal is mainly distributed in temperate and tropical Asia, and was earlier reported from Assam and West Bengal in India. The species Onomarchus leuconotus (Serville, 1838) is reported here for the first time in peninsular India from the Western Ghats (Chandoli National Park, Kolhapur, Maharashtra). This record extends the known geographical range of this species by about 1630 km. As its holotype is not described from India, the female of O. leuconotus is described here via detailed diagnostic characters, colour photographs and illustrations.

An integrated approach was used to study the seasonal influence on the abundance and diversity of phytoplankton and zooplankton in the Swarnamukhi River Estuary (SRE) and the adjacent coast covering five stations by collecting monthly samples from the years 2014 to 2017. A total of 54 phytoplankton species conforming to four families and 58 zooplankton species conforming to nine families were recorded. Phytoplankton abundance and richness were high during pre-monsoon (PRM - 56410 cells/L) followed by monsoon (MON – 42210 cells/L). A similar trend was observed in the case of zooplankton, where abundance was recorded high during PRM (124261 ind./m3) followed by MON (111579 ind./m3). Moreover, phytoplankton and zooplankton were dominated by the diatoms and copepods, respectively. Both phytoplankton and zooplankton exhibited significant temporal (F= 26.4, p <0.05) and spatial (F= 32.1, p <0.05) variations. The higher density and abundance were recorded in the inner stations compared to the open sea. The present study reveals that the SRE have a rich diversity which could be attributed to a higher nutrient influx in the inner stations. The anthropogenic discharge from the surrounding aqua farms, agricultural land, and human settlement area could cause concerns for the local flora and fauna if a proper mitigation plan is not evolved through long-term monitoring study in this coastal region.

Platerus pilcheri Distant, 1903, a harpactorine reduviid, is rediscovered from India after more than a century since its original description. A brief diagnosis of this species, a note on its range extension, a distributional map, and images of live habitus are provided along with the images of a syntype preserved in the Natural History Museum, London (BMNH). We also present a comparison with the other Indian congeneric species, Platerus bhavanii Livingstone & Ravichandran, 1991, and show that this latter species does not belong in the genus Platerus and is to be treated as species inquirenda. The issue of the subsequent documentation of Platerus bhavanii from Karnataka is also discussed.

We summarize the knowledge on taxonomy and distribution of the genus Parnassia in Vietnam. Two species of the genus are found in Vietnam. We report additional records of P. wightiana, which appears to inhabit the provinces Ha Giang and Yen Bai. We provide detailed morphological description of the Vietnamese populations of this species, and discuss their deviation from the known variation range of P. wightiana. We report for the first time the second species of Parnassia from Vietnam, and provisionally identify it as P. procul. Our discovery of this species in Lam Dong Province in southern Vietnam is the first record of the genus outside the northern highlands within the country. We illustrate both Vietnamese species of Parnassia with analytical photographs, and show their distribution on a map. Additionally, we present an updated checklist of the family Celastraceae in Vietnam, which reflects the most recent views on taxonomic boundaries of the family and its genera, and includes discoveries of the last years as well as some earlier reports absent in the previous works. In total, 17 genera and 93 species are accepted in the checklist.

Grasmick et al.’s Low Self-Control Scale (LSCS) is considered the gold-standard of self-control measures due to the frequency of its use in criminology. The aim of the present study is to examine the psychometric properties of the LSCS from a more modern psychometric perspective and develop a shorter version. Our sample consisted of young adults ( N = 610, M = 21.33 years, SD = 3.09) from Portugal. The six-factor intercorrelated model of the LSCS showed an adequate fit, but models that would legitimate using a total score could not be confirmed. The subscales’ intercorrelations revealed some low non-significant correlations. The six subscales showed distinctive correlates with other measures, with three subscales presenting some problematic correlations. Confirmatory factor analysis was subsequently used to develop a three-factor shorter version with strong cross-gender measurement invariance and good reliability. Findings have implications for the validity of the general theory of crime specifically which components of self-control have the greatest empirical linkages to conduct problems and related deviance.
Reinvestigation of the Psychological Mechanisms of Construction Experience on Hazard Recognition Performance
Authors: Zhou Xiaoshan , Liao Pin-Chao , Xu Qingwen
Published: February 2022

Objective

The study aimed to reinvestigate psychological mechanisms of the influence of construction workers’ experience on hazard recognition performance, with signal detection theory (SDT) and electroencephalogram (EEG) readings.

Background

Existing evidence regarding the effect of experience on hazard recognition performance in the construction industry remains inconsistent. Behavior-wise, identification of dominant hazard recognition factors (sensitivity or response bias, or both) would help determine appropriate training strategies to improve hazard recognition. In terms of neuro-responses, induced gamma-band activity was expected to reflect the cognitive functions mediating the psychological effects of experience.

Method

Seventy-seven construction workers participated in a predesigned hazard recognition task, in which participants judged whether a hazard was present from a series of construction scenario pictures. We computed and compared the sensitivity and response bias of SDT and time-frequency representations of recorded EEG signals of the two experience-level groups.

Results

Novice workers had higher hazard recognition rates. Behavior-wise, novices were more sensitive than more experienced workers. Compared with experienced workers, novices showed stronger gamma-band difference power (hazardous minus safe) in the left frontal and right posterior parietal areas during the hazard recognition process.

Conclusion

Novices performed better at hazard recognition, indicating their sensitivity to the hazards without a clear difference in response bias. Based on the EEG data, novices’ sensitivity may be attributed to more efficient working memory and attentional control.

Application

There is a need for continuous refreshment of hazard recognition skills for experienced workers for safety interventions.
