Published: November 2023

Sleep Apnea (SA) can cause health complications including heart stroke and neurological disorders. The Polysomnography (PSG) test can detect the severity of sleep disturbance. However, it is expensive and requires a dedicated sleep laboratory and expertise to examine the patients. Therefore, it is not available to a large population in developing countries. This leads to the development of cost-effective and automated patient examination methods for the detection of sleep apnea. This study suggests an approach of using the ECG signals to categorize sleep apnea. In this work, we have devised an original technique of feature space designing by intelligently hybridizing the multirate processing, a mix of wavelet-empirical mode decomposition (W-EMD), modes-based Hjorth features extraction, and Adam-based optimized Multilayer perceptron neural network (MLPNN) for automated categorization of apnea. A publicly available ECG dataset is used for evaluating the performance of the suggested approach. Experiments are performed for four different sub-bands of the considered ECG signals. For each selected sub-band, five "Intrinsic Mode Functions" (IMFs) are extracted. Onward, three Hjorth features: complexity, activity, and mobility are mined from each IMF. In this way, four feature sets are formed based on wavelet-driven selected sub-bands. The performance of optimized MLPNN, for the apnea categorization, is compared for each feature set. Five different evaluation parameters are used to assess the performance. For the same dataset, a systematic comparison with current state-of-the-artwork has been done. Results have shown a classification accuracy of 98.12%.

Published: November 2023

Background

U.S. data on opioid prescribing by dentists are limited to 2019. More recent data are needed to understand the effect of the COVID-19 outbreak on dental opioid prescribing, characterize current practices, and determine if dental opioid stewardship initiatives are still warranted.

Objective

To evaluate the association between the COVID-19 outbreak and the rate of opioid prescribing by U.S. dentists

Methods

During February—April 2023, the authors conducted a cross-sectional analysis of the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed in U.S. retail pharmacies. The authors calculated the monthly dental opioid dispensing rate, defined as the monthly number of dispensed opioid prescriptions from dentists per 100,000 U.S. individuals, during January 2016-February 2020 and June 2020-December 2022. To prevent distortions in trends, data from March–May 2020, when dental opioid dispensing declined sharply, were excluded. Using linear segmented regression models, the authors assessed for level and slope changes in the dental opioid dispensing rate during June 2020.

Results

Analyses included 81,189,605 dental opioid prescriptions. The annual number of prescriptions declined from 16,105,634 in 2016 to 8,910,437 in 2022 (-44.7%). During January 2016-February 2020, the dental opioid dispensing rate declined -3.9 (95% CI: -4.3, -3.6) per month. In June 2020, this rate abruptly increased by 31.4 (95% CI: 19.3, 43.5) and the monthly decline in the dental opioid dispensing rate slowed to -2.1 (95% CI: -2.6, -1.6) per month. As a result, 6.1 million more dental opioid prescriptions were dispensed during June 2020-December 2022 than would be predicted had trends during January 2016-February 2020 continued.

Discussion

U.S. dental opioid prescribing is declining, but the rate of this decline slowed after the COVID-19 outbreak. Findings highlight the continued importance of dental opioid stewardship initiatives.

There are no clear boundaries between internal tissues in sheep Computerized Tomography images, and it is difficult for traditional methods to meet the requirements of image segmentation in application. Deep learning has shown excellent performance in image analysis. In this context, we investigated the Loin CT image segmentation of sheep based on deep learning models. The Fully Convolutional Neural Network (FCN) and 5 different UNet models were applied in image segmentation on the data set of 1471 CT images including the Loin part from 25 Australian White rams and Dolper rams using the method of 5-fold cross validation. After 10 independent runs, different evaluation metrics were applied to assess the performances of the models. All models showed excellent results in terms evaluation metrics. There were slight differences among the results from the six models, and Attention-UNet outperformed others methods with 0.998±0.009 in accuracy, 4.391±0.338 in AVER_HD, 0.90±0.012 in MIOU and 0.95±0.007 in DICE, respectively, while the optimal value of LOSS was 0.029±0.018 from Channel-UNet, and the running time of ResNet34-UNet is the shortest.

Published: November 2023

Introduction

Parkinson’s disease is neurodegenerative, complex and progressive, manifesting in a slow and irreversible way. Physical exercise has been proposed as therapeutic alternative to people with Parkinson´s disease.

Objective

To synthesize knowledge about the effects of physical exercise on people with Parkinson´s Disease as presented by published systematic reviews.

Methods

Nine electronic databases and two grey literature databases were searched for systematic reviews reporting the effects of physical exercises on people with Parkinson´s Disease. Searches involved a two-phase process, by, at least, two independent reviewers. Methodological quality of the included systematic reviews was assessed using AMSTAR-2.

Results

From 2,122 systematic reviews, 139 were included. Motor outcomes were assessed in 91% of the studies, with balance being the most studied. Non-motor outcomes were assessed in 68% of the studies, with emphasis on quality of life. Physical exercises were classified into five categories: aerobic exercises, strength, combined, sensorimotor activities and other activity protocols. Findings of the systematic reviews suggest that all exercise categories can be prescribed to improve balance and mobility, while combined exercises, strength, and specific activities improve both motor and non-motor outcomes, and aerobic exercise and sensorimotor activities improve motor outcomes.

Conclusion

Current evidence from systematic reviews suggests that physical exercises impacts both motor and non-motor outcomes in people with Parkinson´s Disease. Limits in evidence provided by the systematic reviews were related to methodological issues and to the description of the interventions and must be considered to improve decision-making and clinical application.
The impact of digital financial inclusion and urbanization on agricultural mechanization: Evidence from counties of China
Authors: Liu Cunjing , Chen Lei , Li Zhezhou , Wu Difan
Published: November 2023

This paper expounds the theoretical logic among digital inclusive finance, urbanization, and agricultural mechanization level, puts forward the research hypothesis, and then selects the county unbalanced panel data of 1309 counties in China from 2014 to 2020 based on the two-way fixed model with standard error clustering to county level and mediating effect model for empirical data regression analysis. Through baseline regression analysis, mediation effect analysis, and heterogeneity analysis, the findings of this paper are as follows. First, digital financial inclusion has a significant positive effect on the growth of agricultural mechanization. Second, digital inclusive finance at the county level can also indirectly affect the growth of agricultural mechanization through urbanization. That is, agricultural mechanization has an intermediary effect between the financial agglomeration at the county level and the growth of farmers’ income. Third, the impact of county-level digital financial inclusion on the growth of agricultural mechanization level is significantly heterogeneous, and the promoting effect is significant in areas with balanced grain production, national-level poor county or contiguous areas of dire poverty, and areas with a good foundation for digital financial inclusion. By analyzing digital inclusive finance, urbanization, and agricultural mechanization, this paper proposes targeted policy recommendations. First, the government can promote agricultural mechanization by developing digital financial inclusion. Second, the government should guide and accelerate the process of digital financial inclusion, promoting urbanization thereby amplifying the positive impact of digital financial inclusion on agricultural mechanization. Third, given the heterogeneity of the impact of digital financial inclusion on agricultural mechanization, local development should focus on developing different dimensions of digital financial inclusion according to specific conditions.

Candida albicans, the primary etiology of human mycoses, is well-adapted to catabolize proline to obtain energy to initiate morphological switching (yeast to hyphal) and for growth. We report that put1-/- and put2-/- strains, carrying defective Proline UTilization genes, display remarkable proline sensitivity with put2-/- mutants being hypersensitive due to the accumulation of the toxic intermediate pyrroline-5-carboxylate (P5C), which inhibits mitochondrial respiration. The put1-/- and put2-/- mutations attenuate virulence in Drosophila and murine candidemia models and decrease survival in human neutrophils and whole blood. Using intravital 2-photon microscopy and label-free non-linear imaging, we visualized the initial stages of C. albicans cells infecting a kidney in real-time, directly deep in the tissue of a living mouse, and observed morphological switching of wildtype but not of put2-/- cells. Multiple members of the Candida species complex, including C. auris, are capable of using proline as a sole energy source. Our results indicate that a tailored proline metabolic network tuned to the mammalian host environment is a key feature of opportunistic fungal pathogens.
Ritual seks - Sex als ritueller Akt der Heiligenverehrung
Authors: Gottowik Volker
Published: November 2023

Die Wahrnehmung des Islam in Indonesien ist radikal auf seine lebensfeindlichen bis gewaltbereiten Komponenten verkürzt. Dagegen setzt Volker Gottowik einen anderen Akzent. Er fokussiert auf heterodoxe Praktiken, die im Kontext von Pilgerfahrt und Heiligenverehrung auf Java untersucht werden. Dazu gehören ritualisierte Sexualkontakte (ritual seks), die Pilger untereinander eingehen, um den Segen des verehrten Heiligen zu empfangen. Im Zentrum der Analyse stehen die gesellschaftlichen Reaktionen auf solche Praktiken. Die Rückschlüsse, die daraus gezogen werden, zeigen deutlich: Eine erweiterte Perspektive auf Islam und Islamisierung ist dringend notwendig.

An assessment of surgery core rotation quality at osteopathic medical schools
Authors: Casey Taylor , Brennan Zachary , Pereira Kenneth , Young Grace , Paluri Sarin N. , Gudakunst Craig
Published: November 2023

Context

Osteopathic medical schools have traditionally placed a heavy emphasis on the field of primary care. While graduating osteopathic students continue to pursue family medicine, internal medicine, and pediatrics at higher rates than their allopathic counterparts, it is unknown whether students feel that surgical rotations are held to similar standards.

Objectives

The purpose of this study was to assess osteopathic medical student opinions of the quality of their surgical clerkships and to determine if good or poor experiences influenced their decision to continue pursuing surgery.

Methods

After Institutional Review Board approval, a voluntary and anonymous Qualtrics survey was sent to all nationally registered members of the American College of Osteopathic Surgeons, Medical Student Section (ACOS-MSS) in their final 2 years of medical school. Analyses were conducted utilizing R statistical software.

Results

A total of 345 responses were recorded from the Qualtrics survey sent to 2182 ACOS students from the national registry (response rate of 15.8 %). Students who found a mentor during their surgical rotations were more likely to consider a surgical career after they completed their rotations (odds ratio [OR]=1.43, p=0.003). Students at academic sites had more opportunities for research than those at community hospitals (p=0.019). Most students responded that they were still considering surgery as a career after rotation completion; a significant portion (OR=0.36, p<0.001) responded that they were no longer interested.

Conclusions

Medical students are most likely to review a surgical rotation favorably if they can connect with a mentor while on rotation. Osteopathic medical schools may benefit from instituting mentorship programs for students interested in surgery, as well as ensuring that their students have ample opportunity for research.
Judaica Librarianship: Back to the Future
Authors: Catanese Anthony
Published: November 2023

The Library of Congress Classification system was designed during the age of colonialism, and as such, poorly represents the information-seeking behavior of present-day users. Students of Judaica are especially hindered by the limited scope of the B class (Philosophy and Religion) of the Library of Congress Classification system, which extensively classifies Christian material, but limits the thematic classification of Judaic subjects. Qualitative data collected on students of Jewish thought via a proposed questionnaire is anticipated to shed light on the specialized information-seeking behavior of Judaic students. The thematic coding and analysis of such data would assist in selecting an appropriate classification system that will complement Judaica scholarship or facilitate the creation of a novel classification system. More inclusively, such an endeavor may contribute to the understanding of specialized efforts in librarianship.

Published: November 2023

Highly stable pulsed fiber lasers are key optical components in optical communication, optical sensing, and precision micromachining systems due to the high beam quality, high peak power, and compact configurations. However, the available optical modulators in the fiber laser suffer from the operation bandwidth limitations and poor long-term physicochemical stability. Here, we have investigated the broadband nonlinear optical absorption behavior of the chromium iodide (CrI3) film, which exhibits broadband saturable absorption towards the mid-infrared regime and excellent long-term stability. The conventional soliton fiber laser operating at telecom wavelength has been obtained from an Er3+-doped fiber laser (EDFL) utilizing CrI3 film with a signal-to-noise ratio (SNR) of 92.4 dB and a pulse width of 492 fs. In addition, a passively Q-switched operation around 2.8 μm has also been obtained from an Er3+-doped ZBLAN fiber laser (EDZFL) modulated by the CrI3 film with a SNR of 46.8 dB and a pulse width of 766 ns. The demonstration shows that the CrI3 film exhibits robust broadband optical modulation, and may make inroads for developing highly stable ultrafast optoelectronic devices.
Ultrafast snapshots of terahertz electric potentials across ring-shaped quantum barriers

Published: November 2023

Probing the time evolution of the terahertz electric field within subwavelength dimensions plays a crucial role in observing the nanoscale lightwave interactions with fundamental excitations in condensed-matter systems and in artificial structures, such as metamaterials. Here, we propose a novel probing method for measuring terahertz electric potentials across nanogaps using a combination of optical and terahertz pulse excitations. To achieve this, we employ ring-shaped nanogaps that enclose a metallic island, allowing us to capture tunneling charges when subjected to terahertz electromagnetic pulse illumination. By controlling and manipulating the terahertz tunneling charges through a focused optical gate pulse, we can obtain the terahertz potential strength as a function of spatial coordinates and time delays between pulses. To accurately quantify the time evolution of terahertz electric potential across quantum barriers, we carefully calibrate the recorded nonlinear tunneling current. Its on-resonance and off-resonance behaviors are also discussed, providing valuable insights into the antenna’s characteristics and performance.

Effects of Joule heating and reaction mechanisms on couple stress fluid flow with peristalsis in the presence of a porous material through an inclined channel

Published: November 2023

The objective of this study is to assess the flow behavior of the peristalsis mechanism of a couple stress fluid in incorporating a porous material. In addition, reaction mechanism and Ohmic heating are also taken into consideration with slip boundary conditions. For the purposes of mathematical simulation, we assume a long-wavelength approximation, ignoring the wave number and taking a low Reynolds number into account. The obtained outcome is shown in a graphical manner and then analyzed. The results of this investigation reveal that when the Hartmann number improves, the pattern of velocity noticeably decelerates. The Lorentz forces have a retarding impact on the velocity of the fluid from a physical standpoint. As the couple stress variable rises, so does the velocity of the fluid. As the couple stress component increases, the skin friction coefficient increases in one region of the fluid channel and falls in another region, between x = 0.5 and x = 1. As the thermal slip variable rises, more heat is transferred through the surface to the fluid, resulting in a rise in the temperature profile. When the couple stress variable is raised, the Nusselt number rises, while the thermal radiation factor causes the Nusselt number to decline. The results showed a positive relationship between the Sherwood number and the reaction mechanism parameter. This study demonstrates the potential use of this research in the fields of a career in engineering, namely, in enhancing hydraulic systems, as well as in medicine, particularly in optimizing gastrointestinal processes. The process of dissection facilitates the unimpeded circulation of blood and lymph inside the vascular system of the body, enabling the delivery of oxygen to tissues and the elimination of waste materials.

Published: November 2023

Phosphoprotein phosphatases (PPPs) regulate major signaling pathways, but the determinants of phosphatase specificity are poorly understood. This is because methods to investigate this at scale are lacking. Here, we develop a novel in vitro assay, MRBLE:Dephos, that allows multiplexing of dephosphorylation reactions to determine phosphatase preferences. Using MRBLE:Dephos, we establish amino acid preferences of the residues surrounding the dephosphorylation site for PP1 and PP2A‐B55, which reveals common and unique preferences. To compare the MRBLE:Dephos results to cellular substrates, we focused on mitotic exit that requires extensive dephosphorylation by PP1 and PP2A‐B55. We use specific inhibition of PP1 and PP2A‐B55 in mitotic exit lysates coupled with phosphoproteomics to identify more than 2,000 regulated sites. Importantly, the sites dephosphorylated during mitotic exit reveal key signatures that are consistent with MRBLE:Dephos. Furthermore, integration of our phosphoproteomic data with mitotic interactomes of PP1 and PP2A‐B55 provides insight into how binding of phosphatases to substrates shapes dephosphorylation. Collectively, we develop novel approaches to investigate protein phosphatases that provide insight into mitotic exit regulation.
Navigating wartime communications: multinational corporations in the Russia-Ukraine war
Authors: Kulikov Volodymyr , Simanovskyy Mykhaylo , Eichenberg Abigail , Braese Ksenija Angelina
Published: November 2023

This article explores the communication strategies of multinational corporations in response to the Russo-Ukrainian War and the public pressure to divest from the Russian domestic market. By content analyzing official statements from the top 50 revenue-generating multinational corporations in Russia, the article identifies patterns in corporate narratives about the war, their actions and concerns, and potential solutions. The findings reveal that most companies declare scaling down their presence in Russia while maintaining certain basic obligations, prioritizing employee safety, and expressing concerns about the global economy. While few explicitly condemn Russia's aggression, many adopt neutral language to avoid naming Russia as the aggressor. Corporations emphasize the importance of diplomacy, adherence to international law, and the pursuit of peace, but often avoid proposing concrete solutions. Despite variations across industries, countries of origin, and decisions to stay or leave Russia, the differences in statements were not significant. The uniformity of corporate statements and evidence that companies frequently do not follow their declared promises suggest potential “bluewashing” – making vague or false claims of social responsibility or anti-war stances to improve their public image. These findings emphasize the need for multinational corporations to develop sincere and original wartime communication strategies.

Published: November 2023

The aim of this research is to examine the mathematical language use of mathematics teachers in detail within the framework of the theoretical approach of “Three Worlds of Mathematics” put forward by Tall (2007). The research was carried out in the case study pattern, which is one of the qualitative research methods. The study group of the research consists of 27 math teachers. In the research, “Worksheet for the Use of Mathematical Language”, which includes four mathematical situations, was used as a data collection tool. In the analysis of the data collected within the scope of the research, the interpretation of the “Three Worlds of Mathematics” theoretical approach towards the use of mathematical language was adopted. As a result of the research, it was seen that mathematics teachers used mathematical language mostly in the context of the “conceptual-embodied world”, and least in the context of the “axiomatic-formal world”. At the same time, while the mathematical world in which the mathematical situation is presented affects the mathematical language used by the teachers for that situation, the teachers could not fully reflect the mathematical language to different worlds whilst working on mathematical situations. Finally, based on the conclusion that teachers use mathematical language in a more qualified way while performing high-level skills, it is suggested to include activities that allow the development of high-level skills in mathematics lessons and that serve to understand and develop mathematics

Arguably amongst the ways refugees can adapt to the society they migrate to is their knowledge and competence in the use of Information and Communication Technologies (ICT). One of the ways that refugees who had to migrate from their countries due to compulsory reasons could make their lives easier in the country they migrated to was the use of The Internet with the developing technology. In this study conducted to investigate the digital lives of refugees in Türkiye, purposive sampling was used, and data were collected from the study group through an open-ended questionnaire. 14 participants participated in the open-ended questionnaire and the data were collected face-to-face. The data collected from the participants through open-ended questionnaires were analyzed using the content analysis technique. As a result of the study, it was found that digital technologies facilitate the lives of refugees in Türkiye. According to the results obtained from the research findings, it was found that all of the refugees have internet access, they use ICTs in their daily lives for communication and for keeping in touch with family and friends, and they want to improve themselves in ICT use. Based on these findings, the use of ICTs by refugees emerges as a situation in which they want to facilitate their life in Türkiye.
Scaling Students’ Self-Efficacy on Machine Translation Post-Editing: Psychometric Properties of the Scale and Their Associations
Authors: Lİ Qing , HUANG Tai-yi
Published: November 2023

Machine Translation Post-Editing (MTPE) has emerged as a productivity-enhancing practice in the language service industry, where human editors correct the output of machine translation systems. To ensure that students of translation possess the necessary skills for MTPE, it is essential to understand their self-efficacy in this domain. This research paper aims to assess students' self-efficacy in translation learning, specifically in the context of MTPE, and explore the factor structure, psychometric properties, and internal associations of their self-efficacy. The study utilized a modified survey adapted from the Scale for Assessing Translators' Self-Efficacy and collected responses from 65 undergraduate students in a Chinese university. The survey data underwent reliability and validity analyses, including exploratory factor analysis, to assess the measurement tool's consistency, stability, and construct validity. The results indicated a high reliability of the scale (Cronbach's Alpha = 0.914) and revealed three primary dimensions of self-efficacy: Decision-making of MTPE, Communicative Competence of MTPE, and Strategic Competence of MTPE, and the strong inter-correlations suggests that they collectively measure the construct of translators' self-efficacy of MTPE, providing insights into the skills and abilities required for effective MTPE. The findings contribute to the development of psychometric tools for further research in translation and promote pedagogical reform to align with evolving market trends emphasizing human-machine collaborative translation.

Authors: M Cook Sean , Jones Jennifer , A Welsh Joshua
Published: November 2023

Flow cytometry (FCM) is a common extracellular particles (EPs), including viruses and extracellular vesicles (EVs), characterization method. Frameworks such as MIFlowCyt-EV exist to provide reporting guidelines for metadata, controls, and data reporting. However, tools to optimize FCM for EP analysis in a systematic and quantitative way are lacking. Here, we demonstrate a cohesive set of methods and software tools that optimize FCM settings and facilitate cross-platform comparisons for EP studies. We introduce an automated small particle optimization (SPOT) pipeline to optimize FCM fluorescence and light scatter detector settings for EP analysis and leverage quantitative FCM (qFCM) as a tool to further enable FCM optimization of fluorophore panel selection, laser power, pulse statistics, and window extensions. Finally, we demonstrate the value of qFCM to facilitate standardized cross-platform comparisons, irrespective of instrument configuration, settings, and sensitivity in a cross-platform standardization study utilizing a commercially available EV reference material.

The reliability of internal combustion engines becomes an important aspect when traditional fuels with biofuels. Therefore, the development of prognostic models becomes very important for evaluating and predicting the replacement of traditional fuels with biofuels in internal combustion engines. The models have been made to model AVL 5402 engine emission, vibration, and sound pressure parameters using a three-stage statistical regression models. The fifteen parameters might be accurately predicted by a single statistic presented here. Both fuel type (diesel fuel and HVO) and engine parameters that can be adjusted were considered, since this analysis followed the symmetry of the methods. The data analysis process included three distinct steps and symmetric statistical regression testing was performed. The algorithm examined the effectiveness of various engine settings. Finally, the optimal fixed engine parameter and the optimal statistic were used to construct an ANCOVA model. The ANCOVA model improved the accuracy of prediction for all fifteen missing parameters.

BACKGROUND:Currently, there is little data on changes in the parameters of heart rate variability and the appearance of subclinical systolic dysfunction of the left ventricular myocardium in hypertensive patients with the development of diastolic dysfunction.
AIM: To study indicators of heart rate variability and parameters of left ventricular deformation in patients with hypertension depending on the presence of diastolic dysfunction.
MATERIAL AND METHODS: 60 patients with stage I–II hypertension (28 women and 32 men) who were in the cardiology department of the clinical hospital and 30 healthy volunteers (23 men and 7 women) were examined. The mean age of the patients was 42±9.4 years, the age of healthy volunteers was 41.3±3.5 years. All subjects underwent Holter monitoring, echocardiographic determination of left ventricular diastolic dysfunction and global deformity. According to the presence of diastolic function of the left ventricle, patients with hypertension were divided into two groups: the first group included 30 patients without impaired diastolic function of the left ventricle according to the results of echocardiography, the second group included 30 patients with diastolic dysfunction, the third group (control) consisted of healthy volunteers. Correlation analysis was performed using the Spearman test. To compare two samples of continuous independent data, the Mann–Whitney U-test was used with the correction of the obtained p-values using the Benjamin–Hochberg test due to the multiple comparison procedure.
RESULTS: When studying heart rate variability, it was found that the power in the high frequency range in patients of the first group was reduced by 2.1 times compared with the control (p=0.0087), in patients of the second group — by 3.4 times compared with healthy people (p=0.005). An imbalance of vegetative influences and a tendency to increase the balance of sympathetic and parasympathetic activity were found. In the study of the average value of the global deformation, it was found that it is lower by 41% in the second group, and in the third - by 48% compared with the control group (p=0.01 and p=0.0002, respectively). The mean values of the global strain were associated with a decrease in the standard deviation of the values of the normal R–R intervals (r=0.60, p=0.0001), and the end-systolic and diastolic volumes were correlated with the LH/HF index (r=0.51, p=0.0021 and r=0.65, p=0.001, respectively).
CONCLUSION: Heart rate variability and indicators of left ventricular deformation in patients with hypertension are reduced in the presence of its diastolic dysfunction.
Večfunkcionalnost Slovenske vojske v očeh prebivalcev in policistov

Published: November 2023

Temeljna funkcija oboroženih sil v zgodovini je bila obramba države pred zunanjimi grožnjami in oboroženo udejstvovanje v vojni. Sčasoma so oborožene sile dobivale nove vojaške in nevojaške naloge tako v miru kot vojni, doma in v tujini. Postale so večfunkcionalne, saj izvajajo mirovne operacije, varujejo meje, nudijo pomoč policiji, pomagajo v primeru naravnih in drugih nesreč ipd. Slovensko javno mnenje je glede zaupanja v Slovensko vojsko stabilno in ji je vedno zelo naklonjeno, kar ji daje tudi močno legitimnost. Slovenska vojska je ob prelomu stoletja legitimnost gradila predvsem na mirovnih operacijah, v zadnjem obdobju pa predvsem na udejstvovanju na področju zaščite in reševanja. Tudi v letu 2023 tako prebivalci kot policisti najbolj podpirajo to funkcijo Slovenske vojske, čeprav se glede drugih ne strinjajo najbolj.

The Ultimate Guide to SARA Diagnosis and Care: A Review
Authors: Akil Mohd , Meena N.S.
Published: November 2023

Milk production per cow has increased due to better genetics and feeding practices, but high-energy diets can lead to digestive disorders like subacute ruminal acidosis (SARA) which can decrease milk yield and negatively impact cow health. The causes of SARA are excessive intake of rapidly fermentable carbohydrates and inadequate ruminal adaptation, with cows in early and mid-lactation being the most vulnerable. To manage SARA, proper transition from dry to lactation group is important along with monitoring palatability, maintaining a homogeneous TMR, managing forage length, keeping records and providing access to feed and water. A well-maintained resting area is also needed. Smooth transitions are important when changing formulas or forages.This review article covers the causes, diagnostic techniques, preventive and treatment methods of this disease in order to raise awareness about it. SARA is generally observed in high yielding cattle and buffalo so this review article aims to provide valuable information to dairy farmers who own large-scale farms and have high-yielding cattle and buffaloes.
BOARD RESIGNATION IMPACT ON LIMITED LIABILITY COMPANY GOING CONCERN: ABSENCE OF PROVISIONS
Authors: Suhardiman Daniel
Published: November 2023

In Indonesia, matters concerning limited liability companies is mainly governed by Law Number 40 of 2007 on Limited Liability Company (Companies Law). The Companies Law regulates all aspects from the formation of company until the dissolution of company along with the legal consequences. In forming a limited liability company, a company must be formed by 2 (two) or more people. This mandatory provision creates the practice of a limited liability company with 50-50 shareholder composition, especially for private company. Structurally, a limited liability company consists of General Meeting of Shareholders (GMS), the Board of Directors (BOD), and the Board of Commissioners (BOC). Both members of BOD and BOC serve the company with limited terms of office and shall be re-appointed by the GMS. In practice, there is a condition where the GMS fails to re-appoint or replace the BOD and BOC even when all the members of BOD and BOC’s terms of office have been ended. During this period, those members of BOD and BOC can no longer act on behalf the limited liability company. The possibility of such company facing such situation is quite high, especially if the company’s shareholder composition is 50-50. This research aims to discuss and analyse the BOD and BOC whose terms of office have ended without re-appointment or replacement by the GMS. The result shows that since the Companies Law has yet to regulate provision to overcome the described issue, this condition may endanger the operation and the existence of limited liability company. Consequently, the existing Company Law has to be amended to address the aforementioned issue.
