The Effect of Psychological Crime of Virtual Bullying on Social Media on Victims Under the ITE Law

Cyberbullying takes many forms and adapts rapidly to technological developments. This study explores the psychological effects of virtual bullying on social media on victims, with the legal basis set out in Indonesia's Electronic Information and Transaction Law (UU ITE). Online bullying has become a major problem in the digital age, significantly impacting the psychological well-being of victims, and often having a more severe impact than conventional bullying. This study aims to identify the forms of virtual bullying regulated by the ITE Law, analyze the psychological impact on victims, and evaluate the effectiveness of legal protection provided by the ITE Law. Using a normative juridical approach, this research evaluates the articles in the ITE Law that are relevant to cyberbullying and relates them to the cases that occur. The results show that cyberbullying can cause various psychological disorders, including anxiety, depression, and decreased self-esteem. The ITE Law provides a strong legal framework to address these acts, with strict criminal sanctions and protection mechanisms for victims. However, the effectiveness of the ITE Law is highly dependent on consistent implementation by law enforcement as well as increased public awareness and education regarding digital ethics. This study concludes that collaborative efforts between the government, educational institutions, and communities are needed to reduce the incidence of virtual bullying and ensure that victims receive the support they need.

Unraveling Oxygen Vacancies Effect on Chemical Composition, Electronic Structure and Optical Properties of Eu Doped SnO2.

The influence of Eu doping (0.5, 1 and 2 mol.%) and annealing in an oxygen-deficient atmosphere on the structure and optical properties of SnO2 nanoparticles were investigated in relation to electronic structure. The X-ray diffraction (XRD) patterns revealed single-phase tetragonal rutile structure for both synthesized and annealed Eu-doped SnO2 samples, except for the annealed sample with 2 mol.% Eu. The results of X-ray photoelectron spectroscopy (XPS) emphasized that europium incorporated into the SnO2 host lattice with an oxidation state of 3+, which was accompanied by the formation of oxygen vacancies under cation substitution of tetravalent Sn. Moreover, XPS spectra showed the O/Sn ratio, which has been reduced under annealing for creating additional oxygen vacancies. The pulse cathodoluminescence (PCL) demonstrated the concentration dependence of Eu site symmetry. Combination of XRD, XPS and PCL revealed that Eu doping and following annealing induce strongly disordering of the SnO2 crystal lattice. Our findings provide new insight into the interaction of rare-earth metals (Eu) with host SnO2 matrix and new evidence for the importance of oxygen vacancies for optical and electronic structure formation.

Analisis Desain Formulir Elektronik Rawat Jalan di Rumah Sakit

According to the Regulation of the Minister of Health of the Republic of Indonesia Number 269 of 2008 concerning Medical Records, Article 3 Paragraph (2), medical records must include the patient's identity, date and time, and anamnesis results, which should at least include complaints and medical history. Medical records are documented in specially named forms to prevent loss or duplication. Aspects to consider when designing a form include anatomical, physical, and content aspects. This study aims to describe the outpatient electronic medical record form based on these three aspects in hospitals. The research subjects were 1 medical records officer and 1 head of the medical records department. Observations and interviews revealed no issues with filling out or anatomical aspects of the outpatient form. The physical aspects of the form were complete, but there were problems with printing; the paper used was below the 80-gram standard, making it prone to damage and tearing over time, which affects print or writing quality. The content aspects of the electronic outpatient form were appropriate, though issues arose when officers or doctors forgot to enter the date, impacting the completeness of the form.

Suppression of Nonlinear Chorus Wave Growth by Active Control of Gyroresonant Interactions With Electron Hole Deformation

AbstractNonlinear gyroresonant acceleration is an essential mechanism for the formation of relativistic electrons in Earth's radiation belts, yet we still have only limited knowledge of how electron motion interacts nonlinearly with plasma waves. Here we demonstrate the compelling suppression of whistler‐mode chorus emissions as a resonant wave with energetic electrons by tuning an external transmitter signal in space plasmas. Through forcible modification of electron motions via phase trapping by the external waves, the nonlinear gyroresonant current is suppressed along with the electron hole deformation. Moreover, this can decrease the population of relativistic electrons due to the lack of coherent resonant waves seen by the phase‐organized electrons. Understanding such nonlinear wave suppression effects is crucial for a potential active control of Earth's plasma environment.

Prevalence and epidemic pattern of ecdemic multidrug-resistant tuberculosis during 2012–2022 in Hangzhou, China: implication for public health strategies

BackgroundTo assess the prevalence and epidemic pattern of multidrug-resistant tuberculosis in Hangzhou City, Zhejiang Province, China during 2012–2022.MethodsAll the tuberculosis cases undergoing drug susceptibility testing during 2012–2022 were included in this study. De-identified information was extracted from the electronic database Tuberculosis Information Management System for analysis of drug resistance prevalence in Hangzhou and ecdemic multidrug-resistant tuberculosis which originated from other regions. Chi-square tests were used to compare drug resistance rates between different groups, while Chi-square tests for trend were used to evaluate the change of drug resistance rates over the years of 2012–2022. The sources and destinations of ecdemic multidrug-resistant tuberculosis were illustrated using a Sankey diagram.ResultsOf 21,127 cases included in this study, 1119 (5.3%) were multidrug-resistant tuberculosis. A significant decline in multidrug-resistant tuberculosis rates was observed during 2012–2022. There was a significant difference in multidrug-resistant tuberculosis rates among immigrant population and local residents in Hangzhou City. Of 1119 multidrug-resistant tuberculosis cases, 515(46%) were ecdemic multidrug-resistant tuberculosis cases, of which 277(53.8%) were from other parts of Zhejiang Province and 238(46.2%) were from other provinces in China. Anhui, Jiangxi and Sichuan were among top three provinces which were the source of ecdemic multidrug-resistant tuberculosis cases. Three districts including Xiaoshan, Shangcheng and Linping districts had the most cases in Hangzhou. The proportion of ecdemic multidrug-resistant tuberculosis cases in Binjiang, Xiaoshan, Qiantang and Linping districtalso exceeded 30% of total cases.ConclusionsMultidrug-resistant tuberculosis prevalence has been declining in Hangzhou. Migrant population contributed to a significant potion of cases in Hangzhou. Interventions should be tailed to local and migrant residents.

THE LEGAL NATURE OF PUBLIC PROCUREMENT AGREEMENTS AND THE FEATURES OF CONTRACTING IN ELECTRONIC FORM

In the article, based on the analysis of the contractual process, with the help of analytical, formal-logical and comparative legal methods, the legal nature of the peculiarities of public procurement contracts and their difference from other civil-law and economic contracts is clarified, as well as the peculiarities of concluding contracts in electronic form. The relevance of the article is due to the significant importance of contracts on public procurement and the study of the features of concluding contracts in electronic form for the interests of state customers and the state as a whole. In the course of the study, the properties and nature of public procurement contracts and the peculiarities of concluding contracts in electronic form were clarified in the analysis of compliance with the principle of freedom of contract from the beginning of the pre-contractual process stage to the moment of concluding the procurement contract. When clarifying the legal nature of contracts on public procurement and the features of concluding contracts in electronic form, an analysis of the possibility of applying the concept of “a contract as a source of law” to these contracts is carried out. According to the results of the study, the transparency and openness of the entire contractual process, which is controlled by the public and state bodies in order to meet the needs of customers acting in the interests of the state, has been established. Important features of the legal nature of procurement contracts are their mandatory planning, consensuality and payment. The subject structure of these contracts is special, given the competitive nature of these contracts, which are mostly concluded as a result of competitive procedures or simplified procurement. The state takes a special role in these treaties as “a kind of treaty agent.” When concluding contracts on public procurement, the principle of economic profitability and compliance with the requirements of the customer in accordance with current legislation applies. According to the results and conclusions of the study, participants of the contractual process - customers and participants (service providers, contractors, sellers of goods) and specialists in the field of law are suggested to use in their work. Based on the results of the research, it is proposed to supplement Article 640 of the Civil Code of Ukraine with the fifth paragraph, in which to define the registration of procurement contracts in the state treasury bodies, which is mandatory, but is not specified in any legislative act. Also, in paragraph five of the specified article, it is proposed to determine the moment of conclusion of the purchase contract, which is different from the moment of conclusion of other contracts.

Glucose inhibitor tubes in Croatian laboratories: are we doing well?

Reliable and accurate measurement of blood glucose concentration is of crucial importance for making clinical decisions in diagnosis diabetes, gestational diabetes and impaired fasting glucose tolerance. Survey was performed in form of questionnaire. Questionnaire was sent to all Croatian laboratories (N = 204) in electronic form using SurveyMonkey cloud-based software (SurveyMonkey, Inc., San Mateo, USA) as an extra-analytical module of the Croatian EQA (External Quality Assessment) provider Croatian center for external quality assessment (CROQALM) in June 2023. In total 148 (73%) of laboratories responded to the survey. Large proportion of laboratories never use glucose inhibitor tubes for random glucose measurement (more than half) or for glucose function tests (one quarter). Only three laboratories use recommended glycolysis inhibitor citrate. Many other inhibitors are also used, even if some of them are not recommended for plasma glucose measurement. Glucose is almost never (93%) sampled on ice when glucose inhibitor tube is not available. Laboratories in Croatia do not follow the recommended procedures regarding glycolysis inhibitors for glucose determination.

Evaluating the Chemical Reactivity of DFT-Simulated Liquid Water with Hydrated Electrons via the Dual Descriptor.

Modeling the various properties of liquid water, particularly its reactivity, has been a longstanding challenge for simulation methods. Recently, ab initio simulations based on density functional theory (DFT) have come to the fore as tenable methods for calculating the properties and reactivity of water, with varying degrees of success for different exchange-correlation functionals. In particular, hybrid-GGA and meta-GGA functionals have been shown to reproduce many of the structural, dynamical, and energetic properties of water to a high degree of accuracy relative to their computational cost. Here, we show that the dual descriptor (DD) measure of nucleophilicity and electrophilicity, which is sometimes used to elucidate organic chemistry reaction mechanisms, can also be used to characterize the reactivity of DFT-simulated liquid water. The DD is especially apt for understanding the reactivity of excess electrons with water as its calculation explicitly involves adding and removing an excess electron from a reference system. We use the DD to explore the reactivity of water simulated using three different DFT functionals: the LDA functional (LDA), a hybrid-GGA functional (PBE0), and a hybrid meta-GGA functional (SCAN0). Using the DD, we show that the SCAN0 functional with the standard 25% Hartree-Fock exchange produces simulated liquid water with many regions that are far more reactive than either PBE0 or LDA. To understand the implications of these highly reactive regions, we then add a strong nucleophile in the form of an excess electron and find that although PBE0 and LDA predict stable hydrated electrons, the excess electron reacts nearly instantaneously with SCAN0 water via proton abstraction to form a hydrogen atom and hydroxide ion. We show that the DD provides the ability to not only predict whether or not liquid water will react with a hydrated electron but also which particular waters will be involved solely from analyzing pure water configurations generated with each functional. We rationalize this result in terms of the known trap-seeking behavior of injected hydrated electrons, which are able to find the most electronegative region in bulk water. These results highlight the utility of the dual descriptor as a fast and interpretable method for investigating condensed-phase reactivity with excess electrons.

What does e-invoice data bring to SNA and real-time economy?

This paper explores the potential of electronic invoice data to enhance the System of National Accounts (SNA) and facilitate a Real-Time Economy (RTE). The rise of data science and advancements in information and communication technologies have increased the use of big data in economic statistics. E-invoice data is being digitized in Europe to detect VAT fraud, but it also contains a vast amount of information on economic entities that make up the SNA. This study focuses on integrating electronic accounting information to improve the coverage, granularity, and update speed of SNA. The paper examines the concept of RTE, which emphasizes real-time data processing and automation, particularly in Estonia and Finland. It also highlights the benefits and challenges of using invoice data for economic statistics, including issues related to data storage formats, legislative systems, and the coordination of data linkages. The research demonstrates invoice data’s theoretical and practical applications for constructing Input–Output Tables (IOTs) and monitoring financial situations. Despite the technical and institutional hurdles, the study suggests integrating invoice data can significantly transform economic statistics.

Assessment of the vessel position dead reckoning method error

A method of the calculation of vessel dead reckoning coordinates with the accuracy assessment is proposed. It is based on previously derived formulas for the assessment of the uncertainty boundaries for vessel geodetic latitude and longitude during its motion along the ellipsoid surface. The above formulas are used as follows. At first, the latitude and its precision index are calculated. After, they are used for the calculation of the longitude and its precision index. As the result, it is possible to determine uncertainty intervals for vessel coordinates derived with dead reckoning. The implementation of this method for testing an electronic chart display and information system Navi-Sailor 4000 as to the calculation of vessel dead reckoning coordinates with it is shown. The provision of the information about vessel heading and speed through water is carried out to the system in real-time mode by means of a signal simulator. The speed and heading are remaining unchanged during one-hour time interval. During the above time interval, the data about dead reckoning coordinates are recording into a log-file, then the data are converted in a text format and used for the test. The dead reckoning coordinates, calculated by the system, are in the limits of uncertainty assessed with the proposed method. A limitation of the method is that it does not take into account the influence of errors due to rounding because of the finiteness of the computer bit grid. After the elimination of the above limitation, it seems to be possible to use a modernized version of the method as a part of a procedure for testing the navigational systems which give the information about vessel dead reckoning coordinates.

Electronic Health (eHealth) Literacy and Self-Care Behaviors—Results from a Survey of University Students in a Developing Country

eHealth literacy (eHL) is directly linked to disease prevention, health promotion, and improved healthcare outcomes. The objectives of this study are to assess undergraduate university students’ knowledge and perceived skills of finding, appraising, and applying electronic health information to health-related problems, as well as to assess the association of eHL with physical, psychological, and emotional self-care. Methods: The measurement model, comprising four correlated factors based on the 28 valid items from two reliable and valid tests, the ‘eHealth literacy scale (eHEALS)’ and ‘the self-care assessment tool (SCAT)’, was estimated using confirmatory factor analysis (CFA) among a sample of 1557 undergraduate university students in Pakistan. Results: The mean value of the eHEALS ranges between 2.90 and 3.33, indicating that the majority of the respondents had moderate levels of eHL skills. Female respondents and respondents from urban areas have greater levels of perceived eHL skills compared with their male and rural counterparts. The CFA model fit indices show that the goodness of fit values are acceptable: x2 = 7.727, p = 0.000; RMSEA = 0.065; TLI = 0.930, CFI = 0.936, IFI = 0.936, GFI = 0.890, NFI = 0.928, RFI = 0.920, PGFI = 0.754. Conclusion: Electronic health (eHealth) literacy has a strong positive association with physical, psychological, and emotional self-care. However, perceived eHL skills among undergraduate university students are moderate, making them potentially susceptible to health risks. Implications: Our study has several practical implications. Its findings can be used to devise eHealth literacy programs for developing relevant skills among undergraduate university students based on their identified needs.

High color purity aluminate phosphor SryCa1-x-yAl12O19: xEu2+ for lighting and backlight display applications

In the context of the rapid advances in electronic information technology, the advancement of novel high-efficiency narrow-band blue phosphors represents a pivotal step in the advancement of high-quality liquid crystal displays (LCDs), as well as the development of white light-emitting diodes (WLEDs) with a reduced correlated color temperature (CCT). In this study, based on the sensitivity of Eu2+ emission to local environment, the alkaline earth aluminate material CaAl12O19 with high structural symmetry was selected as the matrix, and the symmetry of crystal structure was improved by replacing Ca2+ with Sr2+, the narrow-band emission of the phosphor is realized. The Sr0.9Ca0.09Al12O19: 0.01Eu2+ (SCAO: Eu2+) phosphor exhibited narrow-band emission with the full width at half maximum (FWHM) of 45.76 nm, and the colour purity of up to 95.46 %. Moreover, the internal quantum efficiency (IQE) of SCAO: Eu2+ has been demonstrated to reach 81.70 %. In addition, SCAO: Eu2+ phosphor, (Ba, Sr)2SiO4: Eu2+ phosphor, CaAlSiN3: Eu2+ phosphor, and 275 nm UVLED chips were combined to prepare white LED devices exhibiting a low color temperature (3733 K). The three-band LEDs of SCAO: Eu2+, β-Sialon: Eu2+ and K2SiF6: Mn4+ exhibited a colour gamut covering 84.75 % of the National Television Standards Committee (NTSC) standard. This indicates that the phosphor possesses the characteristics of a highly effective narrow-band blue-light-emitting substance with considerable potential for utilization in lighting and backlighting displays.

Integration of legal databases in the context of EU accession aspirations

It is determined that the process of cooperation within the framework of the European Union has increased the need for identification and exchange of legal information coming from regional and national authorities at the European level. This need is partially met by digitally accessible legal information and the widespread use of the Internet. However, the exchange of legal information is largely limited by the differences that exist in different national legal systems, as well as the differences in their technical systems used to store and display the law on their respective websites. This hinders interaction between the information systems of national and European institutions, despite the increase in the availability of documents in electronic format. At the same time, the interconnection of national and international legal information from various sources and their presentation in the form of linked data of legal knowledge will undoubtedly improve the process of searching for legal information, expanding the possibilities of inquiries that are not currently possible. Moreover, in an increasingly digital society, where the number of cross-border civil and criminal proceedings is rapidly increasing, and given the complex diversity of different legal systems in the EU Member States, the simplification and facilitation of cross-border judicial cooperation is essential to ensure effective access of citizens and businesses to justice. At the same time, the system of identification and metadata should be well known to citizens and specialists in the field of law. In addition, to increase the chances of finding case law that is supported by an identifier and metadata, these court decisions should be searchable - by identifier and a minimal set of metadata - through a common interface. The exchange of digital evidence in the EU is also an important aspect. Currently, countries cooperate using private international law in cross-border criminal cases and exchange digital evidence based on these tools. The choice of tool depends on the countries involved and the type of information required.

Bibliometric analysis of scientific publications on the websites of agricultural institutions of higher and additional education of the Russian Federation

The study of scientific activities of educational institutions of the agro-industrial complex is based on information from their websites and on scientometric indicators. Research work is reflected on all the studied websites and contains data on the topics of scientific research, the work of dissertation councils and data on patents and inventions. The electronic information environment is widely used, digital libraries are being developed, and links to digital library systems are provided. All higher educational institutions have scientific periodicals; the results of scientific research are presented in electronic form. Insufficient completeness of document archives, the spread of materials across the categories of the website, and limited availability of full-text databases are noted. An analysis of the publication activity of organizations was conducted on the basis of the Russian Science Citation Index (RSCI). According to the number of authors with publications in the RSCI, Russian Timiryazev State Agrarian University, Kuban State Agrarian University named after I.T. Trubilin and Vyatka State Agrotechnological University are distinguished with 3219, 300 and 1520 authors, respectively. Publications of employees of the Kuban State Agrarian University, Russian Timiryazev State Agrarian University, Omsk State Agrarian University named after P.A. Stolypin and Ryazan State Agrotechnological University named after P.A. Kostychev have a high citation rate in RSCI. When analysing the dynamics of the number of publications of educational institutions from 2019 to 2023, according to RSCI data, a general trend of increasing the number of scientific publications in agrarian universities was revealed.

Gamma irradiation-induced degradation of hexachlorobenzene in methanol: Kinetics, mechanism and dehalogenation pathway

Hexachlorobenzene (HCB), a persistent organic pollutant (POP) and organochlorine compound (OCC), poses significant environmental and health risks due to its high stability and solubility in fats, oils, and organic solvents. This study investigates the degradation of HCB in methanol using gamma irradiation with a60Co source. A 2 × 10−4 M solution of HCB in methanol was prepared and irradiated at a dose rate of 1.74 Gy/s. The degradation process was monitored using Gas Chromatography-Mass Spectrometry (GC-MS), with optimized parameters for effective separation and analysis of byproducts.The results demonstrated a 100% degradation of HCB at an absorbed dose of approximately 51 kGy. The degradation pathway involved successive dechlorination, forming various chlorinated benzene (CB) byproducts such as pentachlorobenzene (PCB), tetrachlorobenzenes (TeCB), trichlorobenzenes (TCB), dichlorobenzenes (DCB), and ultimately benzene.Ion chromatography (IC) analysis revealed a dose-dependent increase in Cl⁻ concentrations, confirming the efficiency of dechlorination. A chlorine mass balance was performed to evaluate the distribution of chlorine during the degradation process, tracking Cl⁻ ions, CBs, and residual HCB. As the dose increases, the chlorine content in residual HCB decreases significantly, with none remaining at 50.2 kGy and beyond. At 169.5 kGy, nearly all chlorine (99.96%) is unaccounted for, suggesting that it has likely been released as gaseous byproducts, such as Cl₂ or other volatile chlorinated compounds.The formation of solvated electrons and hydrogen radicals initiated the dechlorination process, as evidenced by the identified reaction mechanisms. Kinetic analysis indicated that the degradation followed pseudo-first-order kinetics, with a rate constant of 5 × 10−4 s−1. The study also outlines a dose-dependent trend in radiation chemical yields (G values), initially increasing to a peak of 7.3 × 10−2 molecules per 100 eV at 12.6 kGy and subsequently decreasing to as low as 5.4 × 10−4 at 50.2 kGy.This study highlights the effectiveness of gamma irradiation for the complete degradation of HCB in methanol, offering a promising method for the remediation of POPs-contaminated environments. The proposed mechanism and kinetic properties provide a comprehensive understanding of the radiolytic degradation process, paving the way for further applications in environmental cleanup technologies.
