Analysis of Characteristics of Cooperation Network of Smart Agriculture Technology Companies: China as an Example
Authors: Wang Ke
Published: September 2022

The development of new technology and the Internet has provided opportunities for the development of smart agriculture, but at present, the development of smart agriculture is still in the primary stage and faces many urgent technical problems, so most companies enhance their technological innovation capabilities through cooperation with other companies. This paper analyzes the characteristics of cooperation networks of smart agriculture technology companies and the differences in different stages by collecting companies with which smart agriculture technology companies have cooperation relationships and applying social network analysis. The results show that there are few cooperative relationships between smart agriculture technology companies, mostly with large information technology companies (e.g., Huawei and Alibaba), research institutes, and other non-agricultural companies. In the cooperation network, large information technology companies such as Huawei and Alibaba, China Agricultural University, Chinese Academy of Sciences, and Chinese Academy of Agricultural Sciences occupy important positions. However, the overall network density is low, and the cooperation is not tight enough, indicating that the development of smart agriculture technology companies needs to be improved. The findings of the study can provide suggestions for the development of smart agricultural technology companies.

Probabilistic Slope Stability Evaluation Using Hybrid Metaheuristic Approach
Authors: Zeng Xinhua , Khajehzadeh Mohammad , Iraji Amin , Keawsawasvong Suraparb
Published: September 2022

This paper develops an efficient evolutionary hybrid optimization technique based on the adaptive salp swarm algorithm (ASSA) and pattern search (PS) for the reliability evaluation of earth slopes considering spatial variability of soils under the framework of the limit equilibrium method. In the ASSA, to improve the salp swarm approach's exploration ability while also avoiding premature convergence, two new equations for the leaders' and followers' position updating procedure are introduced. The proposed hybrid algorithm (ASSPS) benefits from the effective global search ability of the adaptive salp swarm algorithm as well as the powerful local search capability of the pattern search method. The suggested ASSPS algorithm's efficiency is confirmed using mathematical test functions, and its findings are compared with the standard salp swarm algorithm as well as some efficient optimization techniques. Then, the ASSPS is applied for calculation of the lowest safety factor and reliability index of earth slopes. The safety factor is formulated using the Morgenstern and Price approach and the advanced first-order second-moment (AFOSM) method is implemented for the reliability calculation model. The ASSPS's efficacy for the evaluation of the minimum reliability index of slopes is investigated by considering two literature-based case studies. The numerical experiments demonstrate that the new algorithm could generate better optimal solutions and significantly outperform other methods in the literature.

Published: September 2022

Purpose: To analyze the intraocular pressure (IOP) lowering effect, prognostic factors, and complications that occurred after iStent inject® or XEN® implantation in South Korea.Methods: We retrospectively analyzed 83 eyes with glaucoma who were followed-up for more than 6 months after iStent inject® or XEN® implantation alone or combination with cataract surgery. The success of surgery was defined as an IOP ≤21 mmHg and IOP reduction ≥20% from preoperative IOP.Results: The average IOP drop rate for 6 months after surgery was 33.80% for iStent inject® (group A, 24 eyes), 24.91% for XEN® (group B, 15 eyes), 20.47% for combined iStent inject® and cataract surgery (group A-1, 32 eyes), and 30.39% for combined XEN® and cataract surgery. The cumulative success rate of 6 months after surgery was 45.5% ± 11.2% for group A, 52.8% ± 15.4% for group B, 51.9% ± 9.0% for group A-1, and 83.3% ± 10.8% for group B-1. The difference in success rates between groups A and B was not statistically significant (p = 0.574), and also between groups A-1 and B-1 (p = 0.079).Conclusions: iStent inject® and XEN® both have a significant effect on lowering IOP, regardless of combining cataract surgery. XEN® implantation led to a statistically significant reduction in IOP lowering medications.

Introduction: Human exposure to microplastics continues to rise. Microplastics are harmful and are suspected of contributing to various health problems in humans, including reduced liver function. Purpose: This study aimed to determine the effect of oral polyvinyl chloride microplastic consumption on alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) levels in Rattus norvegicus Wistar strain. Method: Male Rattus norvegicus Wistar strain experiments were separated into control and experimental groups, with the experimental group receiving a 0.5 mg/day dose of polyvinyl chloride microplastic. The experimental animals' blood was taken using the cardiac puncture technique, and the ALP and GGT levels were determined using the kinetic photometric test method. Result and Discussion: The Shapiro-Wilk normality tests showed that the ALP variable from the control group (P=0.342) and the experimental group (P=0.727) was significantly different from the GGT variable from the control group (P=0.482) and experimental group (P=0.099). Thus, the data for the ALP and GGT variables are claimed to be normally distributed. The ALP variable (P = 0.237) and the GGT variable (P = 0.839) both passed the significant homogeneity test, indicating that the ALP and GGT variable data were homogeneous. The independent comparison test T-test findings indicated that the ALP variable (P=0.602) and the GGT variable (P=0.161) were not statistically significant. Conclusion: The oral administration of polyvinyl chloride microplastic had no significant influence on the ALP and GGT levels in the blood of Rattus norvegicus Wistar strain in the experimental group compared to the control group.
HOW ASEAN PERCEIVE NATURAL DISASTER AS PART OF SECURITY COMMUNITY AGENDA?
Authors: Putri Rahmadewi Alifia , Sudirman Arfin
Published: September 2022

As a disaster-prone area, ASEAN had a set of disaster management mechanisms. In 2011 ASEAN established an institution that focuses on regional disaster management, namely the AHA Centre. However, the AHA Center did not show its significant role in some disasters. This article aimed to determine the obstacles faced by the AHA Center in 4 phases of international disaster management, namely mitigation, preparedness, response, and recovery, and to use the concept of the security community to analyze ASEAN norms, institutions, and collective identity and relation to disaster management through the AHA Centre. The method used is a qualitative research method. The data collection technique collaborated several techniques derived from interviews with Indonesia’s Ministry of Foreign Affairs, the AHA Center, and BNPB RI, document-based research, and internet-based research. This research showed how the AHA Center had played a role in the four phases of disaster management. However, there were still shortcomings such as its limited role, lack of resource management, and mechanisms that only focused on government-to-government. In addition, this shortcoming can also be found stemming from the collective identity of ASEAN, which is applied in its regional disaster management. Thus, this study suggested that the ASEAN policymakers increase the role of the AHA Center in regional disaster management, improve mechanisms and resource management, and establish cross-pillar mechanisms of the ASEAN community.
Determinasi Pakta AUKUS terhadap Keamanan Asia Tenggara
Authors: Wene Adrianus L
Published: September 2022

This paper is intended to analyze the determinations of the AUKUS Pact on the security of the Southeast Asian region. With this aim, the focus of the analysis will lead to the attitude or foreign policy of the countries of the Southeast Asian region and ASEAN's attitude towards the determination made by the AUKUS Pact towards the ASEAN Economic Community. The constellation of international relations in the Indo Pacific shows the struggle of two great powers, namely the United States and China. China's ambition to become a hegemonic regional power is manifested in economic maneuvers through the BRI and political maneuvers through the nine dash line claim in the South China Sea. This offensive Chinese activity poses a threat to the United States. As a reaction to China's maneuvers, the AUKUS Pact promises a balance of power as well as the potential to intensify Asia-Pacific security stability. The excesses of the constellation between the United States and China places Southeast Asian countries in a dilemma, including ASEAN which must be able to take on a role to accommodate common interests in Southeast Asia. This paper uses a historical perspective with the balance of threat theory from Stephen Walt. The findings from the paper are, first, the implications of the AUKUS Pact depend on the attitude of ASEAN member countries with two consequent models, namely creating security stability in the Southeast Asian region or causing security and peace instability; second, differences of opinion among ASEAN member countries emphasize ASEAN's inability to manage conflicts and all potential conflicts that threaten its regional security; third, the choice of balancing, bandwagoning or maintaining balance in different degrees between the United States and China is a rational choice for ASEAN member countries. The existence of the AUKUS Pact requires Southeast Asian countries to continuously develop their security mechanisms and strategies to address any potential that may occur in the future.

Published: September 2022

In recent years, along with local flora, many ornamental plants have been brought from all over the world, including Japanese Sophora (Styphnolobium japonicum (L.) Schott, genus StyphnolobiumSchott, family Fabaceae). The species is widely used in landscape architecture due to its decorative properties. There are 12,000 species belonging to this family in the world, 1,700 of them exist in the former Soviet Union, 550 in the Caucasus and over 400 species in Azerbaijan. S. japonicum is of particular importance when introduced for the purpose of landscaping the Absheron Peninsula. The studies were carried out in 2020–2021 on the Absheron Peninsula, at the experimental site of the Institute of Dendrology of Azerbaijan NAS. The purpose of the study: development of rules for the introduction and adaptation of Japanese Sophora in the conditions of Absheron, identification of biological characteristics, resistance to environmental factors, phytochemical studies and determination of areas of application. To achieve the goals set during the study, different methods were used and phenological observations were carried out in different areas. In the course of the study, seeds collected on the Absheron Peninsula and brought on exchange from the Romanian garden Hortus Botanicus were used. It has been found that most of the seeds of S. japonicum require the same conditions for germination. The percentage of germination of seeds of a fresh crop is 1.5–2.0 times higher than that of the seeds of the previous year. Therefore, freshly harvested S. japonicum seeds should be used when sowing. The research results showed that Japanese Sophora, introduced in the conditions of Absheron, has normal stages of development and produces seeds with high germination.

Phytoplankton of the Murmansk lakes in the urbanized territories water quality assessment
Authors: Denisov Dmitrii B.
Published: September 2022

The first comprehensive studies of phytoplankton of the Murmansk lakes have been carried out. Significant differences in the species composition and structure of algae and cyanoprokaryotes communities comparing with references were revealed. In some lakes, an annual change in the dominant taxa was observed, which reflects a high degree of destabilization of the aquatic ecosystems. The main reason for the observed changes should be considered a sharp change in hydrochemical parameters, primarily – the concentration of nutrients dynamics, because of anthropogenic water pollution. A significant factor is also the toxic effect of a number of trace elements, including heavy metals; the concentration in the water of the studied reservoirs can be many times higher than the references. Cyanoprokaryotes are dominated in Semenovskoye Lake, and bloom-causing potentially toxic species have been revealed. A high bioindicative potential of phytoplankton communities in the urbanized territories of the Arctic zone was noted, which must be taken into account when solving the problems of assessing water quality and normalizing the anthropogenic load on water resources.
An Inspiring Object: A Wedding Uchikake Kimono from the Collection of the National Museum in Kraków and its Multiple Representations
Authors: Możdżyńska-Nawotka Małgorzata
Published: September 2022

The article is concerned with a Japanese wedding uchikake kimono, c. 1800–1850, acquired by distinguished Polish collector Feliks ‘Manggha’ Jasieński in 1900, the nuanced issues surrounding its multiple representations in Polish painting and photography during the period 1900–1908, and the multifarious meanings with which the garment was imbued. The uchikake’s original features exerted a seminal formal influence upon its representations. The interpretive process was also informed by perceptions concerning the woman’s status in society and marriage in Japan and in the West, Western and Japanese artistic traditions, as well as current Japonisme in art and fashion. In each of its representations, the uchikake also conveyed personal meanings important to the artist/wearer.
Education as Social Control: Evidence from School Textbooks after the Civil Rights Movement
Authors: Paglayan Agustina
Published: September 2022

The enfranchisement of Black Americans in 1965 led southern state governments to increase education expenditures in predominantly Black school districts. What motivated these educational investments, a redistributive or a social control logic? To answer this question, I examine the content of state-approved History school textbooks between 1955 and 1975. Did southern states reform textbooks after the Civil Rights Movement in ways that better acknowledged the racial injustice and institutionalized discrimination denounced by Black activists? An comparison of textbooks from Alabama, Indiana and California suggests that the answer is no: while non-Southern states' textbooks became more aligned with activists' demands, in Alabama textbooks remained virtually unchanged and continued to minimize the history of racial discrimination. The findings support a theory of education reform whereby politicians who feel threatened by mass demands for institutional change respond by investing in teaching children that there is little reason to rebel against the status quo.

Published: September 2022

La Fibromialgia es una enfermedad reumatológica cuyos síntomas pueden afectar al patrón motor de la marcha y en consecuencia a la realización de actividades de la vida cotidiana. Estas actividades suelen requerir la habilidad de realizar dos tareas de manera simultánea: una motriz y otra cognitiva, lo que se conoce como tareas duales. Los programas basados en realidad virtual, llamados Exergames, han mostrado importantes beneficios en algunos síntomas de la Fibromialgia. Así, el objetivo fue evaluar el efecto de un programa de intervención de 24 semanas en el patrón motor de la marcha en mujeres con Fibromialgia bajo condiciones simples y duales. Un total de 34 mujeres participaron en el estudio y fueron distribuidas en grupos control y experimental. El grupo control realizó vida normal durante el periodo en el que el grupo experimental se sometió al programa de intervención, al que asistían 2 días en semana durante 60 minutos. Se realizó el 10-meteres-walking-test, analizándose el tiempo en completarlo, número de pasos, cadencia, inclinación del tronco y rango de movimiento de cadera y rodillas. El grupo experimental consiguió mejoras significativas en el tiempo invertido en completar el 10-meters-walking-test tanto bajo condiciones simples (p=0.032) como duales (p=0.027). Además, también se encontraron alteraciones significativas en la cadencia bajo condiciones duales (p=0.023). Por tanto, concluimos que un programa de intervención de 24 semanas basado en Exergames provoca alteraciones en el patrón de la marcha de mujeres con Fibromialgia tanto en condiciones simples como duales.

Background

Proximal protection devices, such as the Mo.Ma system provides better neurological outcomes than the distal filter system in the carotid artery stenting (CAS) procedure. This study first evaluated the safety and efficacy of the Mo.Ma system during CAS in a single tertiary referral hospital from Taiwan. The outcomes of distal vs. proximal embolic protection devices were also studied.

Methods

A total of 294 patients with carotid artery stenosis who underwent the CAS procedure were retrospectively included and divided into two groups: 152 patients in the distal filter system group and 142 patients in the Mo.Ma system. The outcomes of interest were compared between the two groups. The factors contributing to occlusion intolerance (OI) in the Mo.Ma system were evaluated.

Results

The procedure success rates were more than 98% in both groups. No major stroke occurred in this study. The minor stroke rates were 2.8% (4/142) and 4.6% (7/152) in the Mo.Ma system and filter system, respectively (p = 0.419). Patients with hypoalbuminemia significantly predicted the risk of stroke with an odds ratio of 0.08 [95% confidence interval (CI), 0.01–0.68, p = 0.020] per 1 g/day of serum albumin in the filter group. A total of 12 patients developed OI in the Mo.Ma system (12/142, 8%). Low occlusion pressure predicted the occurrence of OI in the Mo.Ma group with the hazard ratios of 0.88 (95% CI: 0.82–0.96) and 0.90 (95% CI: 0.84–0.98) per 1 mmHg of occlusion systolic pressure (OSP) and diastolic pressure (ODP), respectively. We further indicated that patients with an OSP of ≥60 mmHg or an ODP of ≥44 mmHg could tolerate the procedure of occlusion time up to 400 s, while patients with an OSP of <49 mmHg or an ODP of <34 mmHg should undergo the procedure of occlusion time less than 300 s to prevent the occurrence of OI.

Conclusion

We have demonstrated the safety and effectiveness of the Mo.Ma system during CAS in an Asia population. By reducing the occlusion time, our study indicated a lower risk of OI in the Mo.Ma system and proposed the optimal occlusion time according to occlusion pressure to prevent OI during the CAS procedure. Further large-scale and prospective studies are needed to verify our results.

Authors: Song Zhe , Yang Zhenyu , Hou Ming , Shi Xuedong
Published: September 2022

Background

Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common complication following cardiac surgery. Early prediction of CSA-AKI is of great significance for improving patients' prognoses. The aim of this study is to systematically evaluate the predictive performance of machine learning models for CSA-AKI.

Methods

Cochrane Library, PubMed, EMBASE, and Web of Science were searched from inception to 18 March 2022. Risk of bias assessment was performed using PROBAST. Rsoftware (version 4.1.1) was used to calculate the accuracy and C-index of CSA-AKI prediction. The importance of CSA-AKI prediction was defined according to the frequency of related factors in the models.

Results

There were 38 eligible studies included, with a total of 255,943 patients and 60 machine learning models. The models mainly included Logistic Regression (n = 34), Neural Net (n = 6), Support Vector Machine (n = 4), Random Forest (n = 6), Extreme Gradient Boosting (n = 3), Decision Tree (n = 3), Gradient Boosted Machine (n = 1), COX regression (n = 1), κNeural Net (n = 1), and Naïve Bayes (n = 1), of which 51 models with intact recording in the training set and 17 in the validating set. Variables with the highest predicting frequency included Logistic Regression, Neural Net, Support Vector Machine, and Random Forest. The C-index and accuracy wer 0.76 (0.740, 0.780) and 0.72 (0.70, 0.73), respectively, in the training set, and 0.79 (0.75, 0.83) and 0.73 (0.71, 0.74), respectively, in the test set.

Conclusion

The machine learning-based model is effective for the early prediction of CSA-AKI. More machine learning methods based on noninvasive or minimally invasive predictive indicators are needed to improve the predictive performance and make accurate predictions of CSA-AKI. Logistic regression remains currently the most commonly applied model in CSA-AKI prediction, although it is not the one with the best performance. There are other models that would be more effective, such as NNET and XGBoost.

Case report: Three-dimensional printing as an educational tool for optimal lead positioning to left bundle branch pacing
Authors: Wei Hui-Qiang , Xue Yumei , Wu Shulin , Fang Xianhong
Published: September 2022

Left bundle branch pacing (LBBP) has been widely adopted as a physiological pacing approach. However, LBBP fails to achieve in some cases because it is difficult to maintain the orientation of the lead tip perpendicular to the interventricular septum (IVS). Three-dimensional (3D) printing technology has emerged as a promising tool for modeling and teaching cardiovascular interventions. Seeking confirmation of optimal lead placement relative to the IVS, we used 3D printing technology to generate a 3D printed heart from a selected patient with successful and proven LBBP. Our model successfully illustrated that the lead tip was perpendicular to the IVS. Application of the 3D technology has potential to help the early-operator understand the optimal lead placement relative to IVS and diminish the learning-curve.

Our institution (University Hospital “L. Vanvitelli” - Naples, Italy) is a high-volume (HV) center in Naples metropolitan area and many patients are referred there to repeat thyroid fine-needle aspiration cytology (FNAC) after initial FNAC performed in low-volume institutions (LV). The aims of the study were to 1) examine the inter-observer agreement between HV and LV institutions according to the Italian thyroid cytology system, and 2) explore how the discordant FNAC reports were distributed in the European Thyroid Imaging and Reporting Data System (EU-TIRADS) categories. All consecutive cases of repeat FNAC performed at University Hospital “L. Vanvitelli” from January 2016 to December 2021 were retrospectively reviewed. Fleiss’ kappa (κ) was used to assess the inter-observer agreement, and categorical variables were compared by chi-square testing. P < 0.05 was considered statistically significant. A total of 124 nodules from 124 adults (mean age 49 years; mean maximum diameter 19 mm) were evaluated. Initial FNAC reports at LV were: 4 (3.2%) TIR1c, 64 (51.6%) TIR2, 48 (38.7%) TIR3A, 8 (6.5%) TIR3B, 0 TIR4, 0 TIR5. The overall FNAC reports were significantly different between the LV and HV institutions. At repeated FNAC, cytological diagnosis was unchanged in 64 (51.6%) cases including TIR2 and TIR3A results. A downgraded FNAC diagnosis (i.e., TIR2 vs TIR3A, TIR2 vs TIR3B) was observed in 36 (29%) nodules. An upgraded FNAC diagnosis (i.e., TIR3B vs TIR2, TIR3B vs TIR3A, TIR4 vs TIR3A, TIR5 vs TIR2, TIR5 vs TIR3B) was recorded in 24 (19.4%) nodules. The weighted inter-observer agreement between LV and HV institutions was poor (κ=0.133). Changed FNAC results were significantly (p=0.0023) more frequent in nodules at intermediate/high-risk (i.e., EU-TIRADS 4/5) than in those at no/low risk (EU-TIRADS 2/3) [i.e., 32/48 (66.7%) and 28/76 (36.8%), respectively]. Downgraded FNAC results were significantly more frequent in EU-TIRADS 2/3 (p=0.001) while upgraded FNAC were present only in EU-TIRADS 4/5 (24/24, 100.0%). The inter-observer agreement among LV and HV thyroid services was poor. The EU-TIRADS 4 and 5 categories included all the malignant nodules with FNAC results reclassified as higher risk (i.e., TIR3B-TIR4-TIR5) by the high-volume cytology service.

Background

Ischemia and no obstructive coronary artery disease (INOCA) patients who presented coronary microvascular dysfunction (CMD) demonstrate a poor prognosis, yet the risk factors for CMD remain unclear. Subtle changes in thyroid hormone levels within the normal range, especially the free thyroxine (FT4)/free triiodothyronine (FT3) ratio, have been shown to regulate the cardiovascular system. This prospective study investigated the correlation between FT4/FT3 ratio and CMD in euthyroid patients with INOCA.

Methods

This prospective study (www.chictr.org.cn/, ChiCTR2000037112) recruited patients with myocardial ischemia symptoms who underwent both coronary angiography (CAG) and myocardial perfusion imaging (MPI) with dynamic single-photon emission computed tomography (D-SPECT). INOCA was defined as coronary stenosis< 50% and CMD was defined as coronary flow reserve (CFR)<2.5. All patients were excluded from abnormal thyroid function and thyroid disease history.

Results

Among 71 INOCA patients (15 [21.1%] CMD), FT4 and FT4/FT3 ratio in CMD group were significantly higher and both showed significantly moderate correlation with CFR (r=-0.25, p=0.03; r=-0.34, p=0.003, respectively). The ROC curve revealed that FT4/FT3 ratio had the highest efficacy for predicting CMD with an optimized cutoff value>3.39 (AUC 0.78, p<0.001, sensitivity, 80.0%; specificity, 71.4%). Multivariate logistic regression showed that FT4/FT3 ratio was an independent predictor of CMD (OR 7.62, 95% CI 1.12-51.89, p=0.038, P for trend=0.006).

Conclusion

In euthyroid INOCA patients, increased FT4/FT3 ratio levels are associated with the occurrence of CMD, presenting a novel biomarker for improving the risk stratification.
