Cytogenetic Biomonitoring in Buccal Mucosa Cells from Seaport Dockers.

Dockers of seaport working as stevedores are self-employed workers who carry out arduous and dangerous activities. To date, few studies have investigated the human health risks in these professionals. The aim of this study was to evaluate cytogenetic damage in oral cells of dockers of seaports working as stevedores by micronucleus assay in buccal cells. For this study, a total of 26 seaport dockers working as stevedores aged 51.2±8.4 years (all men) were included in this study. All volunteers had worked for at least 3 years. The control group consisted of 25 participants aged 55.2±9.9 years (all men), who did not work in the Port of Santos city. The results showed statistically significant differences (p<0.05) of micronucleated cells in buccal mucosa cells of seaport dockers. Pyknosis, karyolysis and karrhyorexis did not show statistically significant differences (p>0.05) between groups. The results of the present study suggest that seaport dockers present mutagenicity in oral cells.

A Smart Helmet for Secure Monitoring of Miner Data to Improve Safety

Abstract: In recent times, mining has been a dangerous activity taking a severe toll on the lives of miners. Underground mining hazards include gas poisoning, suffocation, roof collapse, and gas explosion. This project aims to develop a smart helmet based on Zigbee wireless technology to build wireless sensor networks for real-time surveillance and monitoring hazardous gases and abnormal levels of temperature and humidity in the mine. These three parameters are continuously being detected using the gas sensor(s), temperature and humidity sensor, and if the predefined limit is crossed, a buzzer and LED will be initiated. Two infrared sensors, one inside and one on the surface of the helmet, are placed to check if the helmet is properly placed and to detect collision from falling debris, respectively. These values are continuously being transmitted to the control room for monitoring. In case of any hazardous situation, the led and buzzer are activated in the control room as well as on the miner’s helmet. The helmet is powered by the energy generated from piezoelectric sensors placed in the miner’s shoes, which work on the principle of vibration detected from the miner’s movement. The safety measures included in our project can drastically help us avoid mining accidents and thus saving invaluable lives.

A Context-Aware Artificial Intelligence-based System to Support Street Crossings For Pedestrians with Visual Impairments

ABSTRACT Artificial intelligence has the potential to support and improve the quality of life of people with disabilities. Mobility is a potentially dangerous activity for people with impaired ability. This article presents an assistive technology solution to assist visually impaired pedestrians in safely crossing the street. We use a signal trilateration technique and deep learning (DL) for image processing to segment visually impaired pedestrians from the rest of pedestrians. The system receives information about the presence of a potential user through WiFi signals from a mobile application installed on the user’s phone. The software runs on an intelligent semaphore originally designed and installed to improve urban mobility in a smart city context. This solution can communicate with users, interpret the traffic situation, and make the necessary adjustments (with the semaphore’s capabilities) to ensure a safe street crossing. The proposed system has been implemented in Maringá, Brazil, for a one-year period. Trial tests carried out with visually impaired pedestrians confirm its feasibility and practicality in a real-life environment.

Effectiveness of Lead and Cadmium Reduction with Adsorption Method using a Combination of Chitosan and Coffee Grounds (Case Study of Industrial Wastewater PT.X Indonesia)

PT. X Indonesia (PXI) is a company engaged in laboratory services in Bekasi Regency. Based on a preliminary study, the concentration of cadmium and lead in wastewater shows that it exceeds the quality standard of PerMenLHK No. P12 of 2020. The presence of cadmium and lead in PXI's wastewater must be resolved immediately to avoid dangerous human activities and polluting the environment. The research was initiated by taking wastewater samples and synthesizing the adsorbent from the combination of chitosan and activated carbon from coffee grounds. The method used in this study is an experimental approach with quantitative descriptive methods based on laboratory data using FT-IR, SEM EDX and AAS instruments. The results showed that chitosan biosorbent and 1.4-gram coffee grounds activated carbon resulted in the highest cadmium metal reduction efficiency of 94.35% and led to a metal reduction efficiency of 90.86%. The results concluded that the adsorbent of chitosan-activated carbon coffee grounds is very effective in reducing cadmium and lead metals in the wastewater of PXI. This research needs to follow up by increasing the mass of activated carbon of coffee grounds to meet quality standards.

Criminal Law Policy in Counteracting the Use of Networking Platforms for Criminal Activity

The transition to the digital economy is often primarily associated with the transfer of economic activities to online platforms. Researchers often call such a transition platformization. The use of global and national platforms gives rise to a completely new type of relationships. Platforms are often created with the use of AI and distributed register technologies. In the economic sphere, the transition to platforms requires the national governments to develop an effective criminal law policy because the emerging relationships in the use of networking platforms need criminal law protection. A special cause for concern is the creation of platforms used for criminal activities. A platform for criminal activities is a special form of organizing computer information specifically structured to enhance the effectiveness of interactions between different groups of people involved in committing crimes. This publicly dangerous action is not reflected in Russian criminal legislation as an independent crime. Research methodology includes the analysis of criminalizing the creation and operation of networking platforms that are used for criminal activities from the standpoint of grounds for criminalization in the doctrine of criminal law. Three groups of factors act as grounds for criminalization: legal-criminological, socio-economic and socio-psychological. The presented work mainly focuses on the analysis of legal-psychological grounds, such as the degree of public danger, relative prevalence of such actions and their typicality, dynamics of actions in terms of the causes and conditions giving rise to them, the possibility of using criminal law measures to influence these actions, the potential of the system of criminal justice. The conducted analysis showed that the criminalization of the creation of support of networking platforms used for criminal activity corresponds to legal-criminological, socio-economic and socio-psychological criteria.

Effectiveness Evaluation of Different IDSs Using Integrated Fuzzy MCDM Model

Cyber-attacks are becoming progressively complicated; hence, the functional issues of intrusion-detection systems (IDSs) present ever-growing challenges. Failing to detect intrusions may jeopardize the trustworthiness of security services, such as privacy preservation, authenticity, and accessibility. To fight these risks, different organizations nowadays use a variety of approaches, techniques, and technologies to safeguard the systems’ credibility. Establishing policies and procedures, raising user awareness, implementing firewall and verification systems, controlling system access, and building computer-issue management groups are all examples of safeguarding methods. There is a lack of sufficient emphasis on the effectiveness of intrusion-detection systems. In enterprises, IDS is used to analyze the potentially dangerous activities taking place within the technological settings. The selection of efficient IDS is a challenging task for organizations. This research evaluates the impact of five popular IDSs for their efficiency and effectiveness in information security. The authors used the fuzzy analytical hierarchy process (AHP) and fuzzy technique for order performance by similarity to ideal solution (TOPSIS)-based integrated multi-criteria decision-making (MCDM) methodology to evaluate the efficacy of the popular IDSs. The findings of this research suggest that most of the IDSs appear to be highly potential tools. Even though Snort is extensively deployed, Suricata has a substantial advantage over Snort. Suricata uses multi-threading functionality in comparison to Snort to boost the processing performance.

Assessment of Health and Safety Risk Among Waste Scavengers in Enugu State, Nigeria

One of the most dangerous and dehumanizing activity in many developing countries is waste scavenging, an act of selecting possible useful or materials from waste materials especially at waste dump sites for purposes of making a living. This act exposes waste scavengers to several occupational health risks and hazards ranging from cuts, needle stick injury, and exposure to particulate matter, disease causing organisms, contaminated food and water, unhygienic working environment, among other health hazards. In Nigeria, population growth has resulted in an uncontrolled increase in waste creation, making it impossible for waste management organizations in various states to cope. Thus, increasing the number of waste scavengers who use waste picking as a daily source of income and a routine vocation to reduce the unemployment gap. This study was therefore performed to assess health and safety risk among waste scavengers in Enugu state, Nigeria with a view to identifying health conditions associated with waste scavengers in the state. This research adopted a descriptive cross-sectional approach in sampling 396 wastes scavengers across the three senatorial districts of Enugu state. A multistage and random sampling technique with instruments of questionnaires as well as risk assessments of the dumpsites were used to achieve the research objectives. Findings revealed that most of the respondents were exposed to all types of hazards with (79.8%) prevalence of physical hazard, (52.3%) prevalence of biological hazard, (61.6%) prevalence of chemical hazard, (60.6%) prevalence of psychological hazard and (95.7%) prevalence of ergonomic hazard. Due to exposures to broken glasses, needles, nails, metals, bottles, trips and falls, dust, machinery, computer equipment, woods, faeces, used condoms, food wastes, decaying materials, insects, rats, snakes, battery, poisoning from insecticides, decaying materials, chemical substances, lifting heavy bags of picked solid waste materials such as metals and plastics. Study recommends the use of PPEs by scavengers and enforcement of the use by government to ensure their exposures to some of these hazards are reduced. Also, recommends collaboration of Government with health workers to organize frequent health education and promotion to educate the waste scavengers on various types of health hazards.

A pilot observational study of recreational trail riding for Veterans with addictive disorders

ObjectivesThe aim of study was to assess the safety, feasibility, and preliminary outcomes of recreational trail riding for Veterans with addictive disorders. DesignThis was an observational pilot study. SettingUnited States Veterans Health Care Administration Medical Center. Participants were 18 Veterans, 13 males and 5 females All had at least one addictive disorder, with most common being alcohol use disorder. InterventionA recreational trail ride of approximately two hours duration. Main outcome measuresAssessment of safety and pre- and post-intervention instruments, The State-Trait Anxiety Inventory, Craving Experience Questionnaire, Positive and Negative Affect Scale and Conner-Davidson Resilience Scale were utilized to assess changes in anxiety, craving, affect, and resilience, respectively. ResultsThe intervention was feasible to utilize for the population studied. In addition, it was possible to conduct the rides in such a way as to minimize risk to participants and there were no serious adverse outcomes to patients, staff, or equines. However, there was one incident that had potential to cause injury. There were significant pre- to post-intervention decreases in anxiety, negative affect and craving as well as increased positive affect. There was not a statistically significant increase in resilience. ConclusionsThese results indicate that recreational trail riding is, at least in some settings, feasible to utilize for this population. The safety assessment indicated that this intervention can be conducted in a manner such that risk can be mitigated. However, trail riding is a dangerous activity that can result in serious injury or death to participants. Thus, such activities should only be considered by programs that have the ability to implement stringent safety protocols. Preliminary outcomes suggest that this intervention has the potential to be beneficial to for Veterans with addictive disorders. Additional, more rigorous randomized, controlled studies are warranted.

There was a relationship between the level of knowledge, attitude and ownership of latrines with open defecation habits (ODF).

‘The man in the middle’: mixed martial arts referees and the production and management of socially desirable risk

ABSTRACT Mixed martial arts (MMA) competition involves one-on-one, full-contact fighting, most often held within the spatial confines of a steel cage and in front of a paying audience. The spectacular entertainment value of this sport, as well as its intrinsic psychological appeal to competitors, is steeped in risk. While the perspectives of athletes and fans on this issue are reasonably well-researched, little is known about a crucial third party in the production and maintenance of risk in competitive fights: that of the referee. In this paper, I attempt to bridge this gap by arguing that referees’ work is centrally important in the construction of socially desirable forms of risk. Specifically, their role involves protecting fighters’ bodies from the damaging excesses of the action which otherwise constitutes the sport’s raison d’être in the eyes of competing athletes and paying fans; but at the same time, this action is something which referees themselves both facilitate and promote. As such, this work sees referees navigate a core tension residing at the heart of MMA, as with other high-risk sports: how and when to define dangerous action as either desirable or undesirable; as exciting or excessive. The paper concludes by highlighting some wider contextual factors shaping referees’ work, which may bear consideration in future studies of the production of risk in sport.

ConTEXT: context-aware adaptive SMS client for drivers to reduce risky driving behaviors

Text messaging while driving has been considered a dangerous activity that may lead to serious injuries and traffic fatalities. Several assistive technologies and solutions have been developed to simplify texting activity. However, due to inconsistent and complex interface design, lack of logical navigational order, lack of context, complicated text-entry layouts, and laborious activities, the existing texting-related activities can lead to accidents. This paper recognized the risky driving patterns using the real-time AutoLog application. Based on this risky driving behavior, we have proposed ConTEXT, a usable SMS client, to overcome the issues pertaining to the usability of textual activities on smartphones while driving. ConTEXT application is evaluated both empirically as well as through real-time AutoLog application. We have collected data from 117 drivers through a questionnaire. The results show that the data are found reliable also alpha scores for all factors seem internally consistent as it ranges from 0.70 to 0.79 which is good. Similarly, we have reported Principal Component Factor Analysis and found satisfied and appropriate as the Eigenvalue for all the factors is greater than zero. Furthermore, results obtained from the AutoLog dataset show an improved user experience, better control over the touch screen with minimum visual, physical, and mental load.

Real time dangerous action warning system based on graph convolution neural network

In order to solve a series of disadvantages of slow efficiency and high cost brought by the traditional human action recognition method based on manual feature extraction, in order to prove the feasibility of using graph convolution neural network and action recognition, a real-time dangerous action alarm system based on graph convolution neural network is designed and implemented. The system includes data collection, human posture estimation, action recognition, dangerous action alarm and other functions. The feasibility of using graph convolution neural network to realize real-time dangerous action alarm system is proved by the system. Even if the graph convolution neural network does not pass the training, it can extract good features only by using the original random initialization parameters. If certain annotation information is given, its effect can be greatly improved. After the system adopts the graph convolution neural network, the action recognition can be more accurate, more efficient, faster and more reliable than the traditional method.

The Influence of Road Traffic on Heavy Metal Contamination of Road Dust and Roadside Soil along A Major RN3 Highway Through a Rural Area in Northeastern Algeria

This study examines the assessment of heavy metal contamination of pavement-side soils. In our case we studied the section of National Highway 3 (RN3). In the environment of sampling sites there is no industry or dangerous activity on the environment, the heavy metals addressed in this study are (Pb, Cu, Cr, Fe, Ni, Zn), their origin being road traffic. Results indicated that concentrations in road dust were higher than in soil. The distribution of heavy metal concentrations in dust is Fe&gt;Pb&gt;Zn&gt;Cu&gt;Cr&gt;Ni, and the distribution in the ground is Fe&gt;Pb&gt;Cu&gt;Zn&gt;Cr&gt;Ni in the direction of Biskra and in the opposite direction and decreases everything away from the road, while the distribution in the central solid ground is Fe&gt; Cu&gt;Cr&gt;Cr&gt;Zn&gt;Ni. Climatic conditions such as wind, rainfall, temperature, humidity and the nature of the terrain were also significantly related to their enrichment in these roadside soils.

Возможности и проблемы использования информации с цифровых носителей при проведении комплексной судебной психолого-психиатрической экспертизы несовершеннолетних, обвиняемых в незаконном распространении наркотиков

The article considers the specifics of the analysis of information from digital media during the conduct of the comprehensive forensic psychological and psychiatric examination of minors accused of illegal drug distribution. The features of the involvement of minors in illegal activities for the distribution of psychoactive substances, the psychological mechanisms of such socially dangerous actions by adolescents are described. Analysis of the products of the subject’s activities in the form of his communicative activity recorded on the Internet, an account in a social network is one of the methods that allows to compose or supplement a holistic psychological portrait of the subject and answer the questions of the judicial and investigative authorities regarding his individual psychological characteristics. When planning and implementing criminal actions directly on the Internet, the task of an expert psychologist is among other things to reconstruct the situation of an offense and highlight regulatory components in the behavior of its participants, which include goal setting, the level of assessment and prediction of the consequences of actions, planning, control and correction actions aimed at achieving illegal goals.

IRON PRODUCTION IN THE NKAR ETHNIC GROUP OF THE GRASSFIELDS OF CAMEROON: THE PLACE OF TRADITIONAL MEDICAL PRACTICES

In the production chain of the African iron working industry, symbolism was present all through these processes. The environmental and cultural context in which these operations took place, were reflected in the type of furnaces, and techniques used in each iron working agglomerate. Symbolism in this study is linked to traditional medical practice, which was identified in the iron working agglomerates in the Nkar polity. Nkar is found in the higher plateau of the Grassfields of Cameroon. This paper made use of primary and secondary sources; together with archaeological techniques as methodology. The study revealed that, in the Nkar ethnic group, traditional medical and pharmaceutical practices were absorbed by iron workers on part time basis. This probed up because, accidents occurred in iron, kaolin and flux mines, and in the dangerous activity of smelting and smiting. These incidents needed first aid treatment. The ability of iron workers to effectively handle these ailments; linked them to traditional medical practitioners as a societal phenomenon. This paper concludes that, the ability of iron workers to handle medical conditions demonstrates an element of symbolism in the African metallurgy, and that, smelters could experiment and implement pharmaceutical/medical procedure. They however, remained mystical in approach.

Peran Bimbingan Konseling Dalam Mengatasi Anak Temper Tantrum

Early childhood is a time to learn to deal with feelings, whether disappointed, sad, angry when what they want is not fulfilled. That's all a natural and natural feeling. Sometimes without us realizing it we as adults clog an emotion, for example distracting a child. However, if this feeling cannot be expressed by the child, there will be a pile of emotions that can later explode and get out of control, and appear like a tamper tantrum. Expressing emotions with dangerous actions is a form of tantrums so that children get what they want or need. The older the child, the more energy he puts into expressing his emotions. Therefore it is difficult for adults to control and prevent uncontrollable behavior. The purpose of this study was to determine the role of counseling guidance in overcoming children with temper tantrums in RA Anak Salih Suwayuwo, precisely in group A children. Researchers used qualitative methods in their research. Counseling guidance at RA Anak Salih Suwayuwo is carried out through various stages of certain services.

The Effectiveness of a Virtual Reality Marketing Video on the People Desire to Buy a Product

Virtual Reality technology can provide new experiences and different points of view of activities, events, or products for the users. In line with advances from VR technology, YouTube initiates to support the spread of VR videos by creating a VR feature on their platform. A hundred videos about a dangerous activity, Horror activity, and Marketing video of software or a movie product are found on the YouTube platform. Meanwhile, it is still not yet known how the effectiveness of an advertisement using VR video via the YouTube platform on the people desires to buy a product, especially in Indonesia, which then became the purpose of this study. In carrying out this study, a quantitative study was used by creating a digital questionnaire and distributed it with Google Forms. Then the data obtained will be processed by the respondent demographics and the 4 types of analysis, such as the Validity analysis, the Reliability analysis, the Ranking of VR applications on product promotions, and the Correlation analysis. Afterward, the study found that the B1 and B2 variables refer to Advertising, making it easy for us to understand the product has the most correlation coefficient. Moreover, 80% of the respondents stated that they like the VR advertisement product. It means that people are interested in trying and feel something new in the way VR technology is given to them. Ultimately, the respondents agree that VR advertising has informed them well about the product.

The GW Miracle in Many-Body Perturbation Theory for the Ionization Potential of Molecules.

We use the GW100 benchmark set to systematically judge the quality of several perturbation theories against high-level quantum chemistry methods. First of all, we revisit the reference CCSD(T) ionization potentials for this popular benchmark set and establish a revised set of CCSD(T) results. Then, for all of these 100 molecules, we calculate the HOMO energy within second and third-order perturbation theory (PT2 and PT3), and, GW as post-Hartree-Fock methods. We found GW to be the most accurate of these three approximations for the ionization potential, by far. Going beyond GW by adding more diagrams is a tedious and dangerous activity: We tried to complement GW with second-order exchange (SOX), with second-order screened exchange (SOSEX), with interacting electron-hole pairs (W TDHF), and with a GW density-matrix (γ GW ). Only the γ GW result has a positive impact. Finally using an improved hybrid functional for the non-interacting Green’s function, considering it as a cheap way to approximate self-consistency, the accuracy of the simplest GW approximation improves even more. We conclude that GW is a miracle: Its subtle balance makes GW both accurate and fast.

Dangerous Recreational Activity

Drowning isn’t the only danger in water - some aquatic animals can be deadly. The scuba diver who dies underwater poses a difficult diagnostic dilemma for investigating authorities and pathologists. Barotrauma caused by the failure of a gasfilled body cavity to equalize its internal pressure with changes in the ambient pressure is another cause of death. Investigation should be thorough and follow a standardized outline. This investigation should include the victim’s past medical and social history, dive profile, a detailed history of the terminal event and resuscitation efforts, environmental conditions, examination of the diving equipment and finally the autopsy.

INFORMATION TERRORISM AS A CONTEMPORARY THREAT TO THE INFORMATION SECURITY OF MAN, SOCIETY AND THE STATE

The article discusses the content and characteristics of information terrorism as a threat to national and international security in contemporary circumstances. The relevance of the topic stems from the fact that information is currently considered a strategic resource, and deliberate manipulation of public opinion and the commission of terrorist acts to that end has become one of the most dangerous manifestations of hybrid confrontation in the contemporary international arena. Due to the impossibility of clear distinction with ordinary computer crimes and domestic manipulation in mass media, the concepts of «information terrorism» and «cyberterrorism» do not have a clear interpretation. Therefore, information terrorism is viewed in a broad sense (manipulation of public consciousness to create tension, instability, chaos aimed at achieving political or economic objectives in the interests of terrorists) and in narrow terms (cyberattacks on critical government infrastructure information systems to disable them, which can lead to economic, environmental and other disasters). The general characteristics of information terrorism (organized form of violence, psychological influence, drawing attention to a particular problem, demonstrative nature) are defined and specific characteristics inherent only in terrorist acts in the information sphere: (secrecy, size, synchrony, remoteness, internationality and publicity) are singled out. The methods of information terrorism are described, which are aimed at influencing people’s consciousness on a large scale and at imposing their will on society and State institutions through the use of disinformation, propaganda, diversification of public opinion, psychological pressure, rumours, manipulation, intimidation. The forms of information terrorism are described: in particular: information-psychological (media-terrorism) and information-technical (cyberterrorism). It is noted that media terrorism / media killer activity involves the organization of special media campaigns to create an atmosphere of civil disobedience, public distrust of the actions and intentions of the government and its law enforcement agencies by using a number of models of communicative influence (nationalist, religious, inciting model). Cyberterrorism is presented as a socially dangerous activity with the use of computers and telecommunication networks to harm or commit actions / threats that threaten society and lead to other serious consequences, through the use of the following methods: APT-attacks, malware, DoS / DDoS-attacks, unauthorized access, ransomware. It is summarized and concluded that today virtual space and mass media are widely used by various terrorist-oriented groups for their own purposes, because accessibility, the absence of censorship, the large potential audience of users, the speed with which information is disseminated and the complexity with which it is presented and received are all contributing to the spread of information terrorism in today’s world. The threat of terrorism through the use of media and cyberspace is a complex challenge of our time. The danger of such terrorism lies in the absence of geographical and national borders, since terrorist acts can be carried out from anywhere in the world, as well as in the difficulty of identifying the identity of the terrorist in the information space and establishing his whereabouts, because cyber and media attacks are carried out by hackers indirectly through the use of computer technology. Therefore, in view of the further development of technology and mass media, the issue of countering information terrorism will be particularly relevant.
