Inteligencia artificial y ciudades: la carrera global hacia la regulación de los algoritmos
Authors:   investigadora principal, Programa Ciudades Globales, CIDOB, Galceran-Vercher Marta
Published: March 2023

Existe una necesidad creciente de asegurar que el desarrollo y uso de aplicaciones de inteligencia artificial (IA) no comprometa los derechos fundamentales. Esto ha precipitado una carrera global entre grandes potencias, foros y organizaciones internacionales, así como empresas y organismos públicos y privados, por fijar los estándares que deben gobernar y regular este fenómeno. Ante un contexto regulatorio global fragmentado, las ciudades se están posicionando como actores normativos muy relevantes. Las ciudades asumen un papel regulador individualmente, mediante el desarrollo de estándares e iniciativas de gobernanza locales, pero también colectivamente, en el marco de alianzas de ciudades como la CC4DR o Eurocities.

Published: March 2023

Floppy eyelid syndrome is a common ophthalmic condition characterized by a sagging eyelid, which causes its spontaneous wrinkling during sleep. It can be a result of local and systemic diseases. A characteristic group of patients who suffer from floppy eyelid syndrome are middle-aged men with an increased body mass index. Obesity in this group of patients is recognized as the strongest risk factor for the occurrence of obstructive sleep apnea syndrome. The aim of the article is to review the diagnostic methods that are used in the case of floppy eyelid syndrome. The paper also discusses therapeutic methods including surgical techniques.

Crystal chemistry of globular layered silicates of the Troitsko-Bainovskoye fre-clay deposit (Middle Urals)
Authors: Simakova Yu. S.
Published: March 2023

Research subject. The composition and crystal chemistry of glauconite from the open deposits (K2cn-cp) of the Poldnevskaya area of the Troitsko-Bainovskoye deposit of fire clays.

Materials and methods. An analysis of the mineralogical and crystallochemical properties of glauconite was carried out using a set of modern analytical methods (“Geonauka” Centre for Collective Use, IG FRC Komi SC UB RAS): X-ray diffractometry, IR-spectroscopy, scanning electron microscopy, modeling of diffraction profiles.

Results and conclusions. The crystal-chemical features of glauconite were determined. Two main glauconite varieties (green and light green) in the rocks of the Zaikovskaya suite were distinguished and their differences and degree of maturity have been established. It was found that dark green globules are close to glauconite and represent a more “mature” variety, while the light green ones are a disordered mixed-layer mineral of the mica (glauconite) – smectite series and are a product of incomplete replacement of the original smectite by glauconite. Phase heterogeneity of glauconite globules was revealed. It has been established that the rocks of the Troitsko-Bainovskoe deposit are exposed to intensive transformation under the influence of acidic surface and technogenic waters, which result in the destruction of the initial minerals and the appearance of secondary mineralization. Clay minerals of the glauconite-bearing rocks are represented by disordered mixed-layer phases of predominantly illite/smectite type.
Geodynamic aspects of the metallogeny-magmatic zonality relationship of orogenic volcanic-plutonic belts
Authors: Kurchavov A. M.
Published: March 2023

Research subject.The orogenic marginal-continental and collisional volcanic-plutonic belts, and the zonality of magmatism and metallogeny within them, as well as the relationship of endogenous metallogeny with magmatic zonality and geodynamics of belt formation.

Materials and methodsinclude the long-term studies of the Devonian and Upper-Paleozoic belts of Kazakhstan and the Cretaceous-Paleogenic belt of Sikhote-Alin; an analysis of the alterations in the material parameters of magmatites; the identification of the front and rear parts of the belts and the arrangement features of metallogenic zones within their limits; and the data on other belts of the world.

Results.For the marginal continental belts, an asymmetric change of the tholeiitic and low-potassium magmatites of the calcareous-alkaline petrochemical series of the frontal zone of the belt into the magmatites of the high-potassium branch of the calcareous-alkaline and shoshonite series of the rear zone (Devonian and Upper Paleozoic belts of Kazakhstan) has been established. In the same direction, the elemental, as well as the genetic type of deposits changes: pyrite copper-polymetallic frontal zones are replaced by molybdenum-copper-porphyry rear zones (near the border with the frontal zone) and then by rare metal ones. This is also characteristic of the Andean and Okhotsk-Chukchi belts. The collision belts are characterised by symmetrical zonality with a change from rare metal deposits in the centre to copper-polymetallic deposits at the edges (Mongolia). In some cases (Sikhote-Alin and Japan), the continuity of the marginal-continental belt is disrupted as a result of the mantle diapir (or plume), symmetrical magmatic and metallogenic zonality occurs with the change of polymetallic manifestations (near the ocean–continent boundary) to rare-metal ones in the distance.Conclusions.The change in the material parameters of the magmatites of the marginal-continental belts correlates with the removal of their ranges from the ocean–continent transition zone to the interior of the latter. In this case, copper-polymetallic pyrite ore formations are replaced by copperporphyry and then by rare metal ones in this direction. This is due to subduction processes. The collision situation is characterised by a symmetrical zonality of material magmatic parameters with respect to the crowding zone and a symmetrical arrangement of metallogenic zones with a change of rare metal deposits in the crowding zone to copper and polymetallic along the frame. These data are important for metallogenic prediction, as well as for palaeotectonic reconstructions.

Published: March 2023

Research subject. The results of the geological and geophysical study of the Earth’s crust on the territory of two regions are presented: the northwestern part of the East European Platform and the adjacent water area, as well as the waters of the East Siberian, Chukchi Seas and the Russian eastern sector of the Arctic Ocean, including the Lomonosov ridge and the Mendeleev–Alpha rise. The research is focused on mapping the Moho, the thickness and type of the Earth's crust necessary to substantiate the outer boundary of the continental shelf.

Materials and methods. The authors’ original materials obtained during the processing of gravimetry and magnetometry data in the VECTOR system were used. Based on the relationship between gravity anomalies and density variations of rocks, the shape, size of the studied objects, and their deep mutual position are characterized.

Results. The constructed schemes and profiles of the deep structure of the Earth's crust, obtained using the VECTOR method, were tested using the European Moho global seismic model. The positive forms of the Moho section and the raised parts of the shelf surface correspond to the positive anomalies of the transformed gravitational field. The spread of the structure of the field of continental anomalies in the Pevek–Anadyr area to the marine part of the territory under consideration can indirectly confirm the belonging of the Lomonosov Cr., the Mendeleev and Alpha ridges to the continental type of crust.

Conclusion. Global, i.e., related to the territory of the globe, three-dimensional models of Moho allow us to expand and deepen the amount of knowledge about the features of the shelf structure. Geopotential fields in the VECTOR system display the tectonics of the studied environment systematically and comprehensively compared to is representation according to the scheme of profile seismic studies.
Manchu-Tungus Studies in Korea: Focusing on the Studies of Third-Generation Scholars
Authors:   Institute for Russian and Altaic Studies, CBNU, Ko Dongho
Published: March 2023

The purpose of this paper is to predict the direction of future research by introducing the achievements on the Manchu-Tungus language by the third-generation Korean scholars. Since the subjects and methods of scholars' research tend to be fixed to some extent, it is thought that understanding the results of research so far will be able to estimate the direction of future research. Manchu-Tungusic research, if the scope of it is broadened, it can include comparison or contrast studies with other languages and typological studies, but in this paper, only Manchu-Tungusic research will be introduced. Also, since this is an introduction to research trends, specific examples and evaluations are deferred to a later date. Studies on the Manchu-Tungus language up to the second generation in Korea mainly focused on books on Qing studies published by the bureau of interpretaion in Joseon dynasty, research on Manchu books published in the Qing Dynasty, and collect and analysis of spoken Manchu-Tungus data in China and Russia was made. The third generation is those born after the 1970s. While the previous generations mainly studied Manchu language philologically and phonologically, they have been conducting grammatical research mainly within the theoretical framework of modern linguistics for the past 10 years. It is also characterized by the fact that they attempt to analyze spoken Manchu-Tungus following the second generation. Research on spoken language materials is expected to become more active in the future as some scholars are carrying out the “Studies of linguistic transcription and annotation of three endangered Tungus languages” project supported by the government.
When Science Interrupts History: New Soviet Man and Posthuman Science in Mikhail Bulgakov’s Heart of a Dog
Authors:   Institute for Russian and Altaic Studies, CBNU, Kim Myungsung
Published: March 2023

This article explores the cultural and conceptual place of humanity in Heart of a Dog, and brings it into line with the novel’s allegorical view of history. Sharik’s transformation allegorically depicts the changes in Russian society after the Bolshevik occupation of the country. Criticizing the rapid collapse of the old Russian tradition and the establishment of a new system, Bulgakov represents the absurd history of the Soviet Union in the novel. Along with the novel’s historical allusions to the New Soviet Man project, the eugenic experiment that sought to enhance human faculties via supposedly scientific ways, issues of humanity and subjectivity are discussed in the scientific advances posed in Heart of a Dog’s metamorphosis story. The novel’s account of how human-enhancing technology served its ideological function after the revolutionary change in Russian history is the author’s response to one of the most provocative and complex issues when the communist regime sought to appropriate the scientific method for political purposes. Bulgakov presents a strong political satire using post-humanistic imagination while contemplating the place of human and humanity at the time when science intervened in human life.
The Ethnonymy of Sakhalin Oroks in the Writings of Researchers (Second Half of the XIX - Early XXI centuries)
Authors:   Institute for Russian and Altaic Studies, CBNU, A. F. Startsev
Published: March 2023

Many Russian and researchers from Japan, Finland, Poland and other states dealt with the problems of ethnonymy and ethnic history of Sakhalin’s oroks. More than twenty ethnic names are noted in their works: Orochon, Olcha, Ulcha, Ulta, Uilta and others. Russian researchers of oroks believe that the etymology of these names is reflected in the words of the oron and ula, meaning “home deer”, and the ethnic names of the oroks are translated In Russian as “reindeer herders”. In addition, modern Russian ethnographers, not taking into account the theory of the ethnic group, explaining that each nation, in addition to the main name of the endoethnonym, may have several more territorial names characteristic of different ethnographic groups. However, post -Soviet researchers began to equate the numerous orki names with one word. In the studies of the post -Soviet period, the ethnonyms of Ulta ~ Uilta ~ Ujlta began to unite Tilda, while the name of the Ujlta, as the original ethnonym of Sakhalin’s orcs, was preferred. The author of this article adheres to a concept, according to which the numerous names of the oroks of Sakhalin in the form of Ulta, Uilta, Ujlta cannot be reduced to one name, since these are different names of ethnographic groups indicating the territory that previouslythe ancestors of the oroks lived. The article critically comprehends the position of researchers who continue to use the term Ujlta instead of the true name of Uilta. Obviously, the current problem of using the ethnonyms of Sakhalin’s oroks can get its final solution only in the works of the new generation of Russian researchers.
Semantic Intersection of Russian Physical Action Verb Groups: Entropy of Destruction Verbs
Authors:   Institute for Russian and Altaic Studies, CBNU, Park Su bin
Published: March 2023

In the study of the thematic verb groups, in particular, the study of the physical action verb has a extremely important meaning. This verb represents a semantic group that essentially conveys the meaning of the verb for action, i.e. aggressive action. By analyzing the semantic structure of physical action verbs, we find meaningful intersections between the verb subgroups, the creative verb group and the destructive verb group. The semantic intersection of creation verbs and destruction verbs can be easily explained from a linguistic point of view. The action designated by the physical action verb involves a change of object. The creation verb and destruction verb have the same semantic structure, but only differ in the interest of the speaker. In creative verbs, the object of the action(=Result) appears to have a higher communicative rank than the material(=Patient). On the other hand, Patient, the object of the physical action in the destructive verb, would rank lower in communication than Result. The semantic correlation between creation and destruction is naturally explained through the entropy of thermodynamics. In a world where energy is constant, an equilibrium is maintained among the three energies of the original object, the physical action, and the object that changes due to the action. Also, just as the meaning of creation and destruction is distinguished according to the speaker's intention and purpose, in thermodynamics, the act of creation and destruction is distinguished according to the direction toward maximum entropy: Is the entropy of the changed object the result of adding negative entropy to the energy of the original object? Or is it the result of applying negative entropy to the world surrounding the object? In addition, the fact that entropy performs a natural function of bringing the universe into a state of dynamic equilibrium suggests that it is the verb of destruction what takes the lead intersecting the meanings of creation and destruction.

OBJECTIVES: The syndrome of sudden infant death (SIDS) affects children aged between one month and one year of age. Although it has long been reported, there is still no known cause. Although it has long been reported, there is still no known cause. The present work aims to raise the profile and prevalence of SIDS in the Federal District, Brazil. METHODS: Descriptive, transversal and retrospective study relating to deaths, beyond autopsies and the demographics of children between 28 days and one year of age was performed at the Institute of Forensic Medicine of the Federal District between 2003 and 2009. RESULTS: The number of infant deaths registered during the study period was 431. Of these, seven (1.62% of total) died while sleeping and four met the conceptual criteria. The mean age was 102.28 (±11.28) days. However, none was diagnosed as SIDS and theirs causes were analyzed. CONCLUSION: There was no report of SIDS in the Federal District between 2003-2009, contrary it was reported in South/South-Eastern of Brazil whose incidence varied between 0.13 and 1/1,000 live births. This finding suggests underdiagnosis and indicates the lack of a SIDS specific protocol for post-mortem identification. This study shows the need to implement an investigative protocol for SIDS, knowledge, and dissemination of the syndrome among health professionals and the community and shows the importance of awareness campaigns and prevention of this phenomenon.
The Traumatic on Having Marriage to Female Teenagers from Divorce Family
Authors: Aprianti Agus
Published: March 2023

Adolescents who experience losing their parents due to divorce will face psychological wounds called trauma. The trauma affects how their view marriage in the future. There were 3 adolescent informants who were interviewed using a phenomenological approach. The trauma felt by teenagers is the fear of being abandoned by their partner, the fear of divorce will happen again, the fear of getting domestic violence and the fear of the spouse’s family not accepting the divorced family background. The traumatic experience of their parents getting divorced in the end made them decide not to get married when they grew up.

Published: March 2023

Continuous emission monitoring (CM) solutions promise to detect large fugitive methane emissions in natural gas infrastructure sooner than traditional leak surveys, and quantification by CM solutions has been proposed as the foundation of measurement-based inventories. This study performed single-blind testing at a controlled release facility (release from 0.4 to 6400 g CH4/h) replicating conditions that were challenging but less complex than typical field conditions. Eleven solutions were tested, including point sensor networks and scanning/imaging solutions. Results indicated 90% probability of detection (POD) of 3-30 kg CH4/h; 6 of 11 solutions achieved POD >50%. False positive rates ranged from 0 to 79%. Six solutions estimated emission rates. For release rate of 0.1-1 kg/h, the solutions' mean relative errors ranged from -44% to +586% with single estimates between -97% and +2077%, with 4 solutions' upper uncertainty exceeding +900%. Above 1 kg/h, mean relative error was -40% to +93%, with two solutions within 20%, and single-estimate relative errors from -82% to +448%. The large variability in performance between CM solutions, coupled with highly uncertain detection, detection limit, and quantification results, indicate that the performance of individual CM solutions should be well understood before relying on results for internal emissions mitigation programs or regulatory reporting.

Published: March 2023

The search for efficient inhibitors of the SARS-CoV-2 enzymes is ongoing due to the continuing COVID-19 pandemic. We report the results of computational modeling of the reactions of the SARS-CoV-2 main protease (MPro ) with four potential covalent inhibitors. Two of them, carmofur and nirmatrelvir, have been shown experimentally the ability to inhibit MPro . Two other compounds, X77A and X77C, were designed computationally in this work, derived from the structure of X77, a non-covalent inhibitor forming a tight surface complex with MPro . We modified the X77 structure by introducing warheads capable of efficient chemical reactions with the catalytic cysteine residue in the M Pro active site. The reaction mechanisms of the four molecules with M Pro were investigated by quantum mechanics/molecular mechanics (QM/MM) calculations using large quantum subsystems. First, at the QM/MM level, we optimized structures of stationary points on the potential energy surfaces corresponding to the reactants, products, intermediates, and transition states along the hypothesized reaction coordinates. Analysis of these structures has informed the selection of collective variables for the subsequent calculations of the Gibbs energy profiles using molecular dynamics simulations with QM/MM potentials (QM/MM MD). In these simulations, the QM part was treated by DFT with the PBE0 functional. The results show that all four compounds form covalent adducts with the catalytic cysteine Cys 145 of MPro . From the chemical perspective, the reactions of these four compounds with M Pro follow three distinct mechanisms. In all cases, the reaction is initiated by a nucleophilic attack of the thiolate group of the deprotonated cysteine residue from the catalytic dyad Cys145-His41 of MPro . In the case of carmofur and X77A, the covalent binding of the thiolate to the ligand is accompanied by the formation of the fluoro-uracil leaving group. The reaction with X77C follows the nucleophilic aromatic substitution SN Ar mechanism. The reaction of M Pro with nirmatrelvir, which has a reactive nitrile group, leads to the formation of the covalent thioimidate adduct with the thiolate of the Cys145 residue in the enzyme active site.

Published: March 2023

A growing antimicrobial crisis has increased demand for antimicrobial materials. It has become increasingly popular to convert polymeric macromolecules into carbonized polymer nanodots (CPDs) in order to achieve highly biocompatible materials with unique properties as a result of the ability to synthesize nanomaterials of the right size and add value to existing stable polymers. This work presents the tuning of polymeric carbon dots (PCDs) for antibacterial application by combining a biocidal polymer with one-pot solvothermal synthesis. PCDs displayed broad-spectrum antibacterial activity via various mechanisms, including inhibition of bacterial cell walls, ROS generation, and antibiotic resistance. Further, these biocidal PCDs were observed to show excitation-independent near-white light emission which on the other hand is generally possible due to mixed sizes, doping, and surface effects. As opposed to the parent biocidal polymer, CD added ROS-mediated bactericidal activity, increased cytocompatibility and nanofibers with anti-adhesive impact and the potential of imaging bacterial cells.
Statistics and Bias-Free Sampling of Reaction Mechanisms from Reaction Network Models
Authors: Rappoport Dmitrij
Published: March 2023

Selection bias is inevitable in manually curated computational reaction databases but can have a significant impact on generalizability of quantum chemical methods and machine learning models derived from these data sets. We propose a new discrete representation of reaction mechanisms as subgraphs of a network of formal bond breaks and bond formations (transition network) composed of all shortest paths between reactant and product nodes. To construct a bias-free data set, the subgraphs between all pairs of network nodes (containing only neutral molecules) are considered. These quasireaction subgraphs include both reactive (reaction subgraphs) and non-reactive instances. The proposed approach thus transforms the problem of obtaining a bias-free data set of reaction mechanisms to binary classification of a set of quasireaction subgraphs that is free from selection bias by construction. We compute the statistics of the topological properties of quasireaction subgraphs in CHO reaction networks and characterize their similarities using clustering with Weisfeiler--Lehman graph kernels.

Objective: To evaluate ECG findings regarding interatrial block and ventricular repolarization and certain biochemical parameters in young patients diagnosed as acute myocarditis with normal ventricular functions. Materials and Methods: 405 patients under the age of 35 who underwent diagnostic coronary angiography between January 2014 and January 2020 were retrospectively analyzed. Patients whose ECG records could not be accessed or quality were not suitable for evaluation, with sudden cardiac death, cardiomyopathy, ejection fraction <50%, diabetes mellitus, hypertension, chronic kidney and liver failure were excluded. Patients who underwent diagnostic angiography for the differential diagnosis of acute myocarditis were assigned to myocarditis group (n: 35), and age– and sex–matched subjects with normal coronary circulation and underwent coronary angiography for any other reason were assigned to control group (n: 35). Results: Heart rate, P wave duration, P wave peak time, PR interval, QRS, QT, and Tp–e interval, QTc, Tp–e/QT and Tp–e/QTc ratios did not differ from each other. Whereas troponin (p<0.001), glucose (p=0.004), LDL (p=0.015), AST (p<0.001), ALT (p<0.026), CRP (p<0.001) levels and neutrophil count (p=0.003) were markedly higher in myocarditis group, HDL was lower (p<0.001). Conclusions: Although biochemical parameters display differences in myocarditis group, ECG findings did not differ.

Objective: In this study, we aim to determine the relationship between neutrophil/lymphocyte ratio (NLR), D-dimer, and mean platelet volume (MPV) parameters with mortality and clinical severity in Covid-19 patients. Materials and Methods: This retrospectively planned study included Covid-19 patients admitted to the emergency department between March 2020 and September 2020. Sociodemographic characteristics, laboratory parameters, and imaging results of the patients were obtained. The patients were grouped according to the development of mortality and clinical follow-up. Results: Seven hundred patients were included in the study and the mean age of the patients was 49.1±18.2 years. Mortality developed in 5.4% (n=38) of the patients. NLR, D-dimer, and MPV levels of patients who developed mortality were higher than those who survived (p<0.001; p <0.001 and p=0.035, respectively). In ROC analysis, >6 NLR levels, >8.45 MPV levels, and >0.57 D-dimer levels were found to be predictive for mortality (p<0.001; p=0.019; p <0.001, respectively). Conclusions: The high NLR, D-dimer, and MPV levels obtained at the time of admission in Covid-19 patients can be used as an indicator of mortality. Elevated NLR and D-dimer levels are useful in determining the severity of the disease and clinical follow-up.

Published: March 2023

The formability of Inconel materials is important to be used in engineering applications such as in fields of aircraft and maritime. The aim of study is to investigate bending characteristic and formability of Inconel 625 material having a property of corrosion resistance and high strength. In the paper, spring-back phenomena of Inconel 625 sheets are focused on experimentally. The 4 specimens for each different die angle are prepared to be bent. The press brake is used for forming Inconel 625 sheets. The die angle is altered from 90˚ to 150˚. The different rolling direction such as 0˚ and 90˚ is chosen to investigate the effect of grain orientation on spring-back of Inconel sheets. The bending radius is constant and set as 2 mm for all bending tests. The spring-back angles and amounts are measured. Results show that as the bending angle is increased, the spring-back amount in units of angle is decreased averagely from 3.35˚ to 2.58˚ for 0˚ rolling direction and maximum spring-back angle is obtained at a die angle of 120˚ for rolling direction of 90˚. Finally, Erichsen cupping test is also applied to determine the deformability of Inconel sheets. It is demonstrated that cup height value has been found as 17.20 mm.

Published: March 2023

The rapid development of the construction industry has driven the construction of engineering projects in China. However, there are currently many construction projects with budget overruns, resulting in reduced economic benefits of the project. Therefore, this paper elaborates the importance of construction budget of engineering projects, and then proposes the reasons for construction budget overrun of engineering projects: imperfect construction budget plan, lack of supervision in the implementation of construction budget plan, insufficient level of cost management personnel, and construction materials affected by the supply market. Finally, we propose measures to solve the budget overrun of engineering project construction: improve the project construction budget plan, strengthen the supervision of the implementation of the project budget plan, improve the professional skills of budget staff, and stabilize the supply price of construction materials.

Samples for the ferrous metals’ spectral analysis were developed espe­cially rapidly, their number increased by 2.3 times. The Institute was transformed into ISO TsNIIchermet in 1974 and included in the Central Research Institute of Ferrous Metallurgy named by I. R Bardin. The branch system of CRMs created in the years ahead ensured the reliability of quality control of raw materi­als and products of the metallurgical complex. The duties of the Head Organization of the Metrological Service of the Ministry of Ferrous Metallurgy of the USSR for measurements of the chemical composition and standard samples were assigned to the institute in 1978. The system of metrological control (MK) was created and introduced into the practice of analytical laboratories at subsequent period (1978 - 1985). Metrological requirements for CRM, measurement methods certification and normatives for operational, internal and external analysis results quality control were established by ISO TsNIIchermeta. Verification of the implementation of MC in analytical laboratories of the metallurgical industry was carried out in the process of their metrological certification, which was carried out by the leading specialists of the institute since 1982. In 1992, the Institute was transformed into a JSC “The Institute for Certified Reference Mate­rials” (ICRM). The Institute is accredited in accordance with the requirements of the International Stan­dard ISO 17034 as a RM producer, in accordance with the requirements of GOST ISO/IEC 17043 as a pro­ficiency provider. The testing analytical center of ICRM is accredited in accordance with GOST ISO/TEC 17025. The article presents the institute’s and its staff current state data.

Facial expressions are one of the ways humans communicate to convey one's emotions to their communication partner nonverbally. Therefore, human facial expressions can be used for various purposes, one of which is knowing customer satisfaction. So far, customers of Bank Rakyat Indonesia (BRI) provide feedback on service quality using only a polling system, namely by filling out a criticism and suggestion form and then entering it in a suggestion box which is distinguished between satisfied and dissatisfied. However, such a method is less effective because it can be easily manipulated by customers and customers are often indifferent to the feedback. So that the improvement of service quality tends to be less effective. This research will design a system that can recognize human facial expressions to determine the level of customer satisfaction with input data in the form of video data taken by a webcam camera with the viola-jones method to detect faces and determine facial patterns. Then the facial data will be classified using the K-Nearest Neighbor method to determine the type of facial expression. Determination of the value of k will determine the success rate of facial expression detection. The processed data will be displayed on a liquid crystal display (LCD) and then stored in a MySQL database. The results showed that the accuracy of facial expression detection was 80.77% from 52 facial expression data.

Advances in information and communication technology encourage the development of operating systems. Windows 10 is one of the most widely used operating systems today. Unfortunately, there are still many who do not know that in the Windows 10 system there are several system vulnerabilities and some bugs. One example is the vulnerability in Server Message Block (SMB) on Windows 10 (CVE-2020-0796). This vulnerability exploits the Buffer Overflow method on one of the Execution Server Message Block (SMB) files. The impact of this attack is that the attacker can perform Remote Control Access on the target device. One of the reasons why this attack can occur is an operating system that has never been updated or uses an old operating system that has lots of bugs. The automatic updating feature is actually very helpful in overcoming this problem. However, there are still many device users who understand the importance of this. This research will explain how the process of attacking the Windows 10 operating system uses the CVE-2020-0796 vulnerability. The hope is that after understanding the readers can know the importance of using the latest version of the operating system and immediately updating the system.

Published: March 2023

Hepatocellular Carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide, with chronic hepatitis B virus (HBV) infection being an important risk factor for HCC. While nucleos(t)ide analog (NA) therapy has succeeded in suppressing HBV replication and decreasing the risk of HCC in patients with HBV infection, there remains a persistent risk of HCC in those patients. Furthermore, previous studies have highlighted worse survival in patients who developed HCC while on successful NA therapy compared to those who developed HCC without previous NA treatment. We conducted a long-term, retrospective case study in 5 patients observed between 10 and 25 years, to further explore the poor outcomes in patients with HBV-associated HCC with or without previous NA therapy. Our study highlights the aggression and recurrence of HCC in patients with HBV infection, well-suppressed on NA therapy. The results of our observation emphasize the need for early referral for liver transplantation in these select patients.
Natriuretic Peptides in Clinical Practice: A Current Review
Authors: J.W. Lee Deborah , Aw Tar-Choon
Published: March 2023

Heart failure is a major clinical problem affecting 64 million people worldwide with a 5-year mortality rate of around 50%. Patients present to the emergency department with inability to breathe properly. Heart failure is an important condition not to be missed as accurate and early diagnosis or exclusion is crucial for timely intervention. Conventionally heart failure was regarded as congestion consequent to fluid accumulation. Currently heart failure is viewed as a complex heterogeneous entity encompassing severity (clinical versus sub-clinical), onset (acute versus chronic), vascular compartment involved (intra- versus extra-vascular), besides fluid accumulation (cardiopulmonary versus generalized). There is a myriad of biomarkers that reflect different parts of heart failure pathophysiology. However, only natriuretic peptides remain as the “gold standard” against which other biomarkers are compared. This review provides a current update on the utility of natriuretic peptides in clinical practice. We will provide a brief overview of natriuretic peptides, the assays, their clinical use in heart failure, some caveats for their use (age, chronic kidney disease, obesity, heart failure with preserved ejection fraction) and highlight some emerging applications.
