Intraoperative monitoring of visual evoked potentials: experience of 240 operations

Background. Intraoperative monitoring (IOM) of visual evoked potentials (VEPs) is used to inform surgeons about impacts on the visual system in order to prevent iatrogenic visual impairment. The VEP monitoring use become widespread only in the last decade; nowadays, there is no generally accepted methodology for its implementation, and the effectiveness of VEP monitoring and the factors determining it have not been sufficiently studied.Aim. The aim of the study was to investigate the factors influencing the VEP monitoring feasibility and effectiveness.Materials and methods. Data from 240 consecutive neurosurgical operations performed using VEP monitoring were retrospectively reviewed. IOM data (registration parameters, presence and type of VEP changes), patient characteristics (gender and age, tumor type and location, presence of preoperative visual dysfunctions), anesthesia parameters and postoperative changes in vision were studied. Statistical analysis was performed using χ2 and Mann–Whitney tests.Results. VEPs were obtained in 91.3 % of eyes with completely or partially preserved vision. The main factors reducing the chances to record VEPs successfully are preoperative visual disorders and the use of inhalation anesthesia. A personalized approach to the selection of reference electrodes and frequency filtering parameters makes it possible to reduce the number of averagings required for VEP recording and accelerate informing surgeons. With successful monitoring 59.1 % of eyes had no noticeable VEP changes; 5.8 % of eyes had signs of intraoperative improvement; 35.1 % had signs of deterioration. Among the last category, 60.7 % of eyes had full VEPs recovery afterwards. After surgery, new visual disorders were detected in 2.6 % of eyes without signs of intraoperative deterioration, in 6.7 % – with temporary deterioration, and in 19.3 % – with signs of deterioration persisted until IOM is finished. Assessing the sensitivity and specificity of VEP monitoring is hampered by the possibility of complications in the early postoperative period and IOM influence on the course and results of the operation. The proportion of total resections was maximal when VEP monitoring was successful. In the subgroup without preoperative visual impairments, the alarms during monitoring were associated with decrease in proportion of total resections proportion due to increase in proportion of subtotal resections.Conclusion. VEP monitoring with a personalized approach allows effective monitoring of visual functions preservation during neurosurgical operations.

Phenomenon of Phubbing in The Communication Patterns of The Influencer Generation

The rapid development of technology in the modern era triggers new characters in society due to the onslaught of information and communication technology development. This is also close to the influencer generation or Gen Z. One of the new characters is Phubbing, which comes from the words “phone” and “snubbing”, which is meant as the phenomenon of insulting or ignoring someone because they are too focused on the device. Previous studies show that 80.2% of influencers or gen Z have phubbed, and 91.3% admitted to having been phubbed by a phubbee due to excessive device use. One can lose trust, disharmonious interpersonal relationships, and empathy. So, this research aims to look at and study the theory of technological determinism from this point of view. To investigate the phubbing phenomenon, a descriptive qualitative approach was used. In addition, to obtain information about phubbing, the research subject used purposive nonprobability sampling method with 8 participants. The results showed that the presence of new media can cause phubbing to change the communication patterns of the influencer generation or Gen Z. Then, the main component of phubbing is the presence of new media. Then, the main component of phubbing is losing one's control over the use of new media. With most audiences considering phubbing as normal, this leads to a social order system that is plunged by technological determinism. The study of phubbing is reinforced by the theory of technological determinism. Technological advances allow audiences to take direct action. This research hopes to open new insights and perspectives in research and offer solutions for audiences to deal with the phenomenon of phubbing in the digital age.

Hydrogen ion concentration ranged between 6.9 to 8.3, concentrations of nutrients viz. nitrate (2.4 – 6.4 mg/100g), phosphate (1.5 - 15.25 mg/100g) potassium (138 – 560 ppm) and concentration of metals like iron, zinc and manganese were found to be higher during monsoon season and lower during premonsoon seasons The overall findings highlight the need for a scientific solution to reduce the use of harmful chemicals and heavy metal contamination from the river system in order to preserve the biodiversity of freshwater and marine ecosystems.

Analisis Kesiapan UMKM dalam Implementasikan SAK EMKM: Studi Kasus UMKM Mitra Alfamart di Karawang

The development of MSMEs is very important for the progress of the Indonesian economy, however, MSMEs face several obstacles in their development, such as not having employees who are experts in their fields and lack of knowledge about how to make financial reporting in accordance with applicable standards (SAK EMKM). The purpose of this study is to determine whether Alfamart's partner MSMEs in Karawang are aware of the issuance of SAK EMKM, have adequate human resources, accrual basis accounting recording system, and whether they have adopted the concept of a business entity. Six business actors who work with Alfamart partners are the subjects of observation, interviews, and documentation in this study, which uses descriptive qualitative research methodology. The data analysis method developed by miles and huberman is data collection, data reduction, data presentation and conclusion drawing. Six different informants were used in source triagulation used for data validity testing. The results of the study state that the majority of business actors who work with alfamart partners are not ready to implement SAK EMKM. This is due to the lack of understanding in the accounting recording system in order to make financial records based on SAK EMKM and not knowing the issuance of SAK EMKM, not having adequate human resources, the accounting recording system applied is still on a cash basis not accrual basis and adopts the concept of a business entity.

Transformasi Tatanan Hukum dan Demokrasi: Analisis Perubahan Struktural Pasca Reformasi

This research aims to examine the transformation of the level of law and democracy after the Indonesian reformation, of course after independence Indonesia experienced many structural changes from the pre-Reformation era to the post-reformation era. At all times, Indonesia has always tried to develop and improve Indonesia’s structural order, so this research uses two problem formulations, namely how the legal order in post-reformation Indonesia is and how democracy is implemented in post-reformation Indonesia. This research is qualitative research with a normative juridical approach. The results of this research show that the legal order in Indonesia after the 1998 reform, Indonesia experienced significant changes in its legal order and democratic system. The following are the main points related to several things, namely the constitution, government system, elections and political parties, legal developments, human rights protection, and regional autonomy. Overall, post-reform, Indonesia has moved towards a more mature democratic system with improvements in the legal order, more open elections, and increased protection of human rights.

Stability of the linearization method applied in tricom-partmental polynomial catenary systems of order (α + β)

This paper aims to identify exchange coefficients of a nonlinear polynomial tri-compartmental catenary system of (α + β) order. This is based on two principal procedures. The first procedure presented is related to the recommended solution consisting of introducing an adequate time t∗ > 0 in a way to be defined. That is to say: wait a moment to allow the exchange to settle in the polynomial (α +β) order nonlinear catenary system after injecting the quantity into the main compartment, then measure this compartment with compartment 2, at this time t∗ > 0. In the second procedure, we apply the Taylor formula to linearize the nonlinear system and identify the exchange coefficients. In the end, we will prove that the linearization method is stable

Promotion on the thermal and mechanical behaviors of epoxy resin using phthalonitrile and functionalized‐SiO2

AbstractThe phenolic‐type phthalonitrile (PN) was added to EP/DDM system in order to enhance the thermal and mechanical performance at high temperature. The influence of the added PN on the curing process of EP/DDM was studied via DSC and the activating energy (Eα) was calculated based on iso‐conversional method. The Eα values corresponding to EP/DDM crosslink reaction remained at about 60 kJ mol−1 while it dramatically increased to 68.2 kJ mol−1 when PN content reached 50 wt% (EP‐PN50). The Tg and char yield at 700°C in N2 increased from141°C, 25.7%, for the neat EP/DDM to 226°C, 68.7% for the EP‐PN50. The measured char yields of the cured blend were higher than the calculated values which implies the interaction between EP/DDM and polyphthalonitrile network. The tensile and bending tests were carried out at 413 K and the modulus of EP‐PN50 remains 2.3 Gpa. On the meantime, the cyano‐functionalized SiO2 (CNSiO2) was prepared to further promote the mechanical behaviors of this resin blend in high temperature. The contact angles of raw SiO2, KH560SiO2, CNSiO2 with EP‐PN50 are 59.3, 52.6, 49.7°, respectively, which confirms the better wettability of CNSiO2 to the EP/PN blend. Furthermore, the tensile and bending tests conducted at 413 K confirmed that the CNSiO2 was more efficient on enhancing the mechanical performance of this EP/DDM/PN system at high temperature.

Study of complex dynamics and novel soliton solutions of the Kraenkel-Manna-Merle model describing saturated ferromagnetic materials

This paper introduces a framework for nonlinear short wave propagation in an external field for saturated ferromagnetic materials with zero conductivity: the Kraenkel-Manna-Merle system. New solutions are produced via the G′/(bG′+G+a)-expansion technique. The suggested method is easier to understand, more precise, and simpler to compute. Specifically, a set of singular-periodic and kink-shaped exact soliton solutions is produced. Contour plots, 3D, and 2D visualizations with suitable parametric values are employed to present the computed solutions, which are derived through constraint conditions. For the development of certain novel soliton structures, the arbitrary functions in the solutions are selected. Moreover, bifurcation and chaos theory are applied to the primary dynamical system in order to provide a qualitative analysis of the system under study. Phase portraits of bifurcation are presented at fixed locations to illustrate different situations about parameter values in the dynamic system. However, adopting techniques for identifying chaos in a dynamical system and applying an external force verifies the occurrence of chaotic behavior in system. These results offer new perspectives that can enhance understanding of the dynamics of the KMM system.

State Space Model Reference Adaptive Control for a Class of Second-Degree Fractional Order Systems with Different Eigenvalues

This study proposes an adaptive control synthesis for a class of second-degree fractional order systems with different eigenvalues in the state-space domain. The proposed fractional order adaptive controller is a generalization of the MRAC controller for the class of scalar fractional order systems. In order to control the fractional order plant, an adaptive state space feedback controller is applied based on the error between the system output and a chosen reference model using a fractional adaptation law to make the fractional order plant track the fractional order reference model. We show that the resulting adaptive regulator is able to stabilize the fractional order second degree system with a satisfying performance. A simulation example illustrating these performance properties is provided along with a comparison with a fractional order sliding mode control (FOSMC) to demonstrate the superiority of the proposed control scheme.

프랑스 배심제의 절차와 최근의 쟁점

Sixteen years after the introduction of the “citizen participation in criminal trials” (hereinafter referred to as “jury trials”) in 2008 with the aim of ensuring public participation in the judiciary and resolving judicial distrust, there is now a consensus on the need to improve the system. In particular, the number of completed cases relative to the number of registered cases has been gradually declining since the mid-2010s, raising the need to strengthen the system. At the same time, some have pointed out the constraints of expanding the scope and scale of jury trials under current conditions, while others have emphasized the constraints imposed by the Constitution, which stipulates the right to be tried by a judge. With these issues in mind, this article examines the French jury system, which has been relatively unexplored, from the perspective of a comparative case study as a way to deepen the debate. Korean jury system is characterized as a mix of the Anglo-American jury system and the continental European lay assessor system. French system shares similarities with Korean system in that the role of the judge in jury trials is relatively greater than that in jury trials in common law countries, and in that the judge and jury make decisions at the guilt and punishment phase, although judges are not bound by the jury's verdict in Korean system. The purpose of this study is to examine the origins, history, structure, and current status of the French jury system, as well as recent changes, in order to find implications for improving the Korean jury system. The nature of the changes in the French jury trial system needs to be examined in the context of assessing the relative level of change. In this perspective, it is difficult to characterize the French jury trial reform as a 'success' or a 'failure'. Recent changes can be assessed as an attempt to refine the conditions of citizen participation in order to make the meaning of a jury verdict clearer. However, it is also true that there are conditions that make it difficult to expand the practice of the jury system in terms of procedures and costs of criminal trials, and that it is not easy to implement alternatives to it. In the end, to narrow the gap between normativism and realism, it is necessary to look at the experience of implementing a system in order to create a detailed system. French case can be seen as an attempt to reinterpret the ideology of the supremacy of juries over judges and the principle of people’s participation to reflect changing times and social contexts, and to find mechanisms to realize it. The principle of people's participation itself has never been denied in the waves of changes. That is the most important implication which can be drawn from the review of the French case.

Reducing Cluster Overlap in Movie Recommendations with IKSOM and Silhouette Clustering

The exponential growth of online material requires the implementation of effective and precise recommendation systems in order to optimize the user experience. Nevertheless, conventional approaches frequently encounter problems such as cluster overlap, which reduces the accuracy of suggestions. This paper presents a new method for minimising the overlap between clusters in movie recommendation systems. It achieves this by combining Improved Kohonen Self-Organizing Maps (IKSOM) with Silhouette Clustering. The proposed method utilises IKSOM to efficiently represent high-dimensional user-item interactions in a two-dimensional space, enabling the formation of distinct and meaningful clusters. Subsequently, Silhouette Clustering is utilised to enhance the separation and cohesion of clusters, hence reducing overlap. The experimental findings show that proposed hybrid model works much better than the baseline techniques, obtaining an RMSE of 0.423 and MAE of 0.216. Additionally, it improves precision (93.6%), recall (94.2%) and F1-score (93.4%). Additionally, the proposed technique demonstrates a high level of accuracy (97.3%) with a precision rate of 95.8%. These results emphasise the method's efficacy in minimising errors and enhancing the overall performance of the recommendation system. The results indicate that combining IKSOM with Silhouette Clustering can improve the precision and dependability of movie recommendation systems by resolving cluster overlap and offering more individualised user experiences. Subsequent research will investigate the implementation of this method in different fields and the integration of supplementary contextual information to enhance the accuracy of recommendations.

GENERAL CHARACTERIZATION OF IDEOLOGICAL SEMIOLOGY BASED ON ROLAND BARTHES’ SEMIOLOGICAL THEORY

This article presents a semiological analysis of ideology on the basis of R. Barthes’ semiological theory. The subject of the study is ideology as a semiological system. R. Barthes begins to consider his semiological theory by distinguishing between primary or “natural” semiology and secondary or mythological semiology. Primary semiology represents “natural” language as a simple jumble of senses, concepts and signs. In its turn, mythology is a secondary semiology, which is superstructured over “natural” language. R. Barthes introduces the concept of ideology through the exposure of mythology. In this context, special attention is paid to the semiological system of mythology, on the basis of the analysis of which ideological semiology is derived. The peculiarity of R. Barthes’ consideration of semiology lies in the definition of the signified, the signifier and the sign in relation to the “natural” and mythological semiological systems. The methodology of this study is based on R. Barthes’ semiological theory. C.G. Jung’s psychoanalytical theory and A.F. Losev’s phenomenological theory are applied to the analysis of social mythology. In turn, the social theories of K. Marx, F. Engels, V.I. Lenin and L. Althusser are used to analyze ideology. The scientific novelty of the study lies in the construction of ideological semiology. The hypothesis of the study is that ideology is a semiological system of the third order, which is based on the decomposition of mythological semiology. For “natural” semiology, the signified is a sense, the signifier is a concept, and the sign includes the signified and the signifier in their unity. In mythological semiology, the signified is a form, the signifier is a concept, and the sign is a meaning. Ideological semiology is superimposed over mythological semiology just as mythological semiology is superimposed over “natural” semiology. The main conclusion of this study is that ideology overcomes and unmasks mythology and returns concrete-historical reality in contrast to mythology, which passes off the real for the eternal and metaphysical. As a consequence of the destruction of mythological semiology, a new ideological semiology is formed. The authors’ special contribution is the substantiation and derivation of the semiological system of ideology, in which the signifier is a symbol, the signified is an interest of a social group, and the sign is reality.

Нарушение международного права в контексте попыток сохранения глобального доминирования

The Ukrainian conflict has triggered serious changes in the systems of strategic security, political and economic world order. Serious changes are taking place in the geopolitical picture of the world. The emergence of a polycentric world is a fundamentally new system of world order, the idea of which is extremely painfully perceived by Western countries, accustomed to consider themselves the center of human civilization since at least the colonial era. It is now obvious that many countries of the "global South", having recovered from the consequences of the colonial era in several decades, want to act in the international arena in their own, and not in Western national interests, based solely on international law and the UN Charter.

Stochastic Analysis of an Industrial System with Preparation Time Repair under Warranty Policy

The main purpose of this study is to examine the behavior of certain industrial systems under the conditions of product warranty policy. Given this policy, we are interested in considering all the parameters of the system in order to study them and show their impact on the proposed system. In order to increase the efficiency of the system and activate the product warranty policy, the system will undergo a preliminary examination for any system failure occurrence to determine the reasons that led to the failure. After completing the initial inspection, the mechanic will decide whether it is a user-caused failure or a manufacturing defect to determine whether or not the repair of the broken appliance is covered by the manufacturer’s contractual warranty policy. All times in the system are assumed as a negative exponential distribution. The expressions for some measures of system effectiveness such as reliability, mean time to system failure (MTSF), and availability are derived using the supplementary variable technique and Laplace transform. Sensitivity analysis and a relative sensitivity are then carried out in order to recognize how each system parameter affects performance measures. Finally, some numerical examples are designed and performed to show how the change of each system parameter affects system performance.

Kinetic Diagram Analysis: A Python Library for Calculating Steady-State Observables of Biochemical Systems Analytically.

Kinetic diagrams are commonly used to represent biochemical systems in order to study phenomena such as free energy transduction and ion selectivity. While numerical methods are commonly used to analyze such kinetic networks, the diagram method by King, Altman and Hill makes it possible to construct exact algebraic expressions for steady-state observables in terms of the rate constants of the kinetic diagram. However, manually obtaining these expressions becomes infeasible for models of even modest complexity as the number of the required intermediate diagrams grows with the factorial of the number of states in the diagram. We developed Kinetic Diagram Analysis (KDA), a Python library that programmatically generates the relevant diagrams and expressions from a user-defined kinetic diagram. KDA outputs symbolic expressions for state probabilities and cycle fluxes at steady-state that can be symbolically manipulated and evaluated to quantify macroscopic system observables. We demonstrate the KDA approach for examples drawn from the biophysics of active secondary transmembrane transporters. For a generic 6-state antiporter model, we show how the introduction of a single leakage transition reduces transport efficiency by quantifying substrate turnover. We apply KDA to a real-world example, the 8-state free exchange model of the small multidrug resistance transporter EmrE of Hussey et al. (J. Gen. Physiol., 2020, 152, e201912437), where a change in transporter phenotype is achieved by biasing two different subsets of kinetic rates: alternating access and substrate unbinding rates. KDA is made available as open source software under the GNU General Public License version 3.

Improving cardiac rehabilitation referral rates in patients with coronary heart disease from diverse communities using an electronic order system

Background: Despite the benefits of cardiac rehabilitation (CR), local and national CR referral and participation rates remain low when compared to established cardiovascular therapies especially amongst racial/ethnic groups. Objectives: This study investigated the effects of the implementation of a CR program and electronic order set (EOS) in a large health system on CR referral and participation rates among a diverse group of patients with coronary heart disease (CHD). Methods: A total of 360 patients from UCSD Health who presented with ACS were prospectively evaluated during initial hospitalization and 6- and 12-weeks post-discharge. Multivariable logistic regression model assessed referral and participation rates by week-1 and -12 post-discharge, adjusting for gender, age, race, ethnicity, geography, and referring physician subspecialty. Results: UCSD CR program implementation led referral rates to increase at week-1 (Pre- 38.6% and Post-54.9%, p = 0.003) and week-12 (Pre- 54.1% and Post- 59.8%, p = 0.386). Post-CR referrals were more likely at week-1 (OR: 1.93, 95% CI 1.27-2.95) and week-12 (OR: 1.26, 95% CI 0.79-2.00). EOS implementation increased referral rates at week-1 (Pre- 40.3% and Post- 58.7%, p<0.001) and week-12 (Pre- 54.9% and Post- 60.4%, p=0.394) with referrals more likely at week-1 (OR: 2.1, 95% CI 1.35-3.29) and week-12 (OR: 1.25, 95% CI 0.795-1.98). Participation in CR following EOS was more likely at both week-1 and week-12. Multivariable analysis revealed disparities in referral based on race, geographic location, and referring physician subspecialty. Conclusion: A CR program and EOS implementation were shown to increase referral rates with long-term potential for increasing referral and participation rates. Condensed Abstract: This prospective study investigated the implementation of a cardiac rehabilitation (CR) program and electronic order set (EOS) within the same health system on CR referral and participation rates. 360 patients with ACS were evaluated over a period of 12 weeks. UCSD CR program and EOS implementation led referral rates to increase at week-1 and -12. CR participation was more likely to increase at week-1 and -12 following EOS. Multivariable analysis revealed disparities in referrals disproportionally affecting racial and ethnic minority groups and rural communities. CR and EOS implementation may increase CR referral rates for diverse patients with CHD.

Construction of integrated network order system of main distribution network based on power grid operation control platform

This study presents a major advance in grid management: the development and deployment of an integrated network command system for the main distribution network. The system integrates cutting-edge information technology, including modules such as command issuance, intelligent routing, security assurance and in-depth data analysis, opening a new era of refined and intelligent power grid management. The research focuses on the application of core technologies such as information communication technology, distributed control system, artificial intelligence and big data analysis, and strengthens the system operation foundation. The chapter on system architecture details the innovative integration of DDQN algorithm and attention mechanism, and carefully constructs intelligent scheduling engine and status monitoring and early warning system, which significantly improves real-time response, decision optimization and active security defense capabilities. Simulation experiments and actual case analysis verify the effectiveness of the system, specifically, the response time is reduced by 75.7%(from 2.1 s to 0.51 s in the traditional system), the data processing speed is still maintained at a high level under high load (100,000 data processing rate is 300/s), and the system stability is as high as 99.97%. The new system also achieved a high degree of automation, reducing annual operation and maintenance costs by 20%, and increasing user satisfaction to 90%, an increase of 28.6% over the previous period. These improvements not only optimize power quality and grid efficiency, but also further confirm that the fault response time is reduced by 30% and the user outage time is reduced by 25%. Therefore, this study not only highlights the innovation of the proposed system, but also demonstrates its significant contribution to accelerating the modernization of power grid management and ensuring safe operation with empirical data.

Longitudinal associations between beta-endorphin, nonsuicidal self-injury and comorbid psychopathology

Homeostasis models posit that nonsuicidal self-injury (NSSI) serves, in part, to upregulate the endogenous opioid system in order to compensate for an opioid deficiency. A few studies have demonstrated lower basal levels of beta-endorphin (BE), an endogenous opioid, in individuals with NSSI. However, longitudinal studies are missing. Hence, the present study aimed to investigate the longitudinal associations between NSSI, comorbid psychopathology (i.e., borderline personality disorder and depressive symptoms), pain sensitivity and basal BE levels in adolescents with NSSI. N = 53 adolescents with NSSI disorder undergoing specialized treatment participated in baseline and one-year follow-up assessments. BE was measured in plasma; pain sensitivity was assessed with a heat pain stimulation paradigm. Associations between BE and change in NSSI, borderline personality disorder and depressive symptoms as well as pain sensitivity were examined using negative binomial and linear regression analyses. We found that an increase in basal BE was significantly associated with a decrease in depressive symptoms. No associations between BE and NSSI, borderline personality disorder symptoms or pain sensitivity were observed. Our findings may confirm a role of plasma BE in the etiology of depressive symptoms but challenge current models of endogenous opioid homeostasis in NSSI.

Advanced eco-friendly power and cooling cogeneration-thermal energy storage utilizing phase change materials and chemisorption in renewable-based configurations

Increasing the reliability, stability, and safety of renewable energy systems depends on the integration of energy storage systems in order to balance energy production and demand. This research introduces an innovative system that combines a chemisorption unit, a phase change material (PCM)-based thermal energy storage (TES) mechanism, and a solar thermal unit with Linear Fresnel Reflectors (LFRs), tailored for residential usage. The system’s performance and dynamics are examined using TRNSYS and MATLAB software tools. Within this system, electricity is produced via a turbine propelled by the pressure differential created by chemical reactions within a chemisorption unit. Concurrently, cooling was facilitated through the ammonia evaporation process within an evaporator. At heat source temperatures between 100–200 °C, the system achieved a maximum electricity output of 2,718.9 W and a cooling rate of 14,601.5 W. The energy efficiency peaked at 46.32 %, and exergy efficiency at 40.78 %. The thermal energy storage component, with a volume of 1.5 m3, achieved a maximum storage capacity of 253.7 kWh. The study shows that higher heat source temperatures enhance production capacity but reduce the coefficient of performance (COP) for cooling by approximately 25 %. Overall, the system demonstrates significant potential for improving the efficiency and reliability of renewable energy systems.
