Negócios e Direitos Humanos: um Terreno Tenso, Minado e Contestado

Abstract This essay aims to critically analyze the recent field of studies known as Business and Human Rights, which addresses the negative impacts of human rights violations at the corporate level, covering theoretical discussions, principles, guidelines, standards, and regulations. We developed the essay focusing on three key topics: the business activities of transnational corporations negatively impact human rights all around the world; the initiatives created in order to address the impacts of business over human rights are discursive and, therefore, distant from the practices; companies and corporations make various attempts to abstain from their responsibility, even if they make symbolic and material reparations. For this, we illustrate the abstention from corporate responsibility through the human rights violations in the case of João Alberto de Freitas’ murder committed by Carrefour security guards in the parking lot of one of its stores in Porto Alegre, in 2020. Throughout the text, we argue that this field reveals the tensions between business and respect for human rights, understanding that this involves a minefield susceptible to being contested. Our contribution lies in indicating paths for the heavier involvement of researchers from the field of management with the real problems that challenge societies, such as human rights violations at the organizational level.

Differences in knowledge of campus security units in helping victims of cardiac arrest before and after basic life support training

Ignorance about how to do cardiopulmonary resuscitation makes someone not provide help. The research aims to determine the effect of basic life support training on security guards' knowledge in helping victims of cardiac arrest. Pre-experimental research design with the One Group Pretest-Posttest Design approach was measured pre-test of security guard knowledge and then given basic life assistance training then 7 days after the training was measured by security guard knowledge. Data collection using a knowledge questionnaire about basic life support. The research was carried out in the campus environment of the Alauddin State Islamic University Makassar in July 2022. 18 security guards were involved in the research. Data were analyzed by the Wilcoxon test using a statistical program for social science software. The security guards who involved in this study were the majority with high school education (72.2%), an average age of 43 years, an average length of service of 13 years. Most of security guards have never received basic life support training (94.4%) and have never provided basic life support (88.9%). The results showed a significant difference in knowledge before and after training (p <0.001) and 94.4% of security guards experienced an increase in knowledge after being given basic life support training. The results of this study strengthen the need for practical and regular basic life assistance training, ideally at work or in the campus environment. Basic life support training increases security guards' knowledge in helping victims of cardiac arrest.

Frequency of Low Back Pain and Its Related Functional Disability in Security Guards

Security guards are integral to many organizations today, especially in Pakistan. However, there is not much research done to discover the health problems associated with the nature of their Job. This study aims to estimate the prevalence of low back pain (LBP) in security guards in two cities in Pakistan. A cross-sectional descriptive study was designed that included male and female security guards who were residents of Islamabad, and Dera Ghazi Khan, aged between 20 and 60 years. A convenience sampling technique was used for sampling, and a total of 580 participants responded to a structured questionnaire after signing the consent form. Feedback was collected hand to hand, and the statistical analysis was done on SPSS V20. The results show that the prevalence of LBP was 74.4% in Islamabad and 65.5% in Dera Ghazi Khan. Out of the total 580 participants (290 participants from Islamabad and 290 participants from Dera Ghazi Khan), 406 participants claimed to experience LBP once, with an overall prevalence of 70.12%. Prolonged standing was the most common aggravating factor other than prolonged sitting and lying. In addition to LBP, pain in other body parts was also reported, including the knee (52.2%), shoulder (14.1%), foot (10.1%), wrist (0.17%), and neck (0.74%). We concluded that the frequency of LBP and relative functional disabilities are higher in security guards due to job ergonomics and prolonged standing.

경비원의 비경비업무 수행에 대한 법적 규제의 문제점과 입법적 대안

The 「Security Act」 stipulates that if a security guard performs non-security work, both the security guard and the security company are subject to criminal punishment, while the affiliated security company is obliged to cancel the security business license. This was originally legislated to prevent security guards from being illegally mobilized at the site of collective complaints and interfering with the legitimate exercise of citizens’ rights. It has become a social problem as it has been expanded and applied by canceling security business permits of security companies. Recently, the Constitutional Court ruled that the provisions of the 「Security Act」 were unconstitutional on the grounds that they violated the freedom of work. In this study, the places where security guards perform security tasks are divided into general security sites and collective civil complaint sites. It is proposed to prepare an amendment to improve the rights and interests of security guards and contribute to the development of the security industry.

EXPLICIT AND IMPLICIT ATTITUDES TOWARDS HARDINESS IN VARIOUS OCCUPATIONAL GROUPS

The aim of the research was to identify the features of explicit and implicit assessments of hardiness and its components obtained for participants whose occupations are associated with risk: security guards, long-distance lorry drivers, footballers from one of the top football league teams; participants with occupations associated with unconditional execution of orders. Measurements were made using specially designed four modifications of the classical IAT and the self-report procedure Bartone’s Dispositional Resilience Scale. The study showed that there are differences in implicit and explicit attitudes towards hardiness and its components in groups of participants from different occupations: most guards and long-distance lorry drivers revealed a negative implicit challenge; the majority of ‘soldiers’ were found to have negative attitudes towards the commitment. The vast majority of long-distance lorry drivers showed matches of the measurements results. The independence of implicit and explicit ‘overall’ attitudes toward hardiness, and their content, is also shown.

Authorized Automatic Vehicle Allowance System

Abstract: In most organizations, the ongoing vehicle entry registration process for visitors, staff, or students entering the organization includes a security guard checking the driver's identification card or looking for a membership sticker on the vehicle's windscreen, which can easily be lost or stolen. This writing process is tiresome and time-demanding, and it is prone to incorrect notes; additionally, backup and sharing of this vehicle information is difficult due to the data being a physical copy. The goal of the Automatic Authorized Vehicle Allowance System is to create a digital picture processing system with the Raspberry Pi that can be used in an entrance parking system. The Raspberry Pi will identify the car with an ultrasonic sensor and photograph it. The device then processes the picture using digital image processing techniques. The system incorporates various algorithms such as localization, normalization, orientation, segmentation, and optical character recognition (OCR), which examines picture characteristics and forecasts license plate numbers. The obtained number plate information is then cross-checked with records stored in a pre-existing database. An administration is in charge of designating a "whitelist," which is a list of vehicles that can join the suggested system. If the car registration is found in the database, a servo motor circuit connected to a Raspberry Pi will open the gate, and after a monitor delay, the gate will shut. The system is built in such a way that it is simple to apply in a short period of time and is cost-effective.

An Internet of Things (IoT) Based Neighbourhood Distress Alert System

To acquiesce to the increase in territorial invasion of communities by hoodlums, bandits and kidnappers every day, some communities have resorted to engage the services of security agents or guards to watch over and alert them in the case of any security breach. However, the neighbourhood s found in some locations especially, in the rural areas impact on the cost of employing guards, and the consequent disagreement amongst residents in the neighbourhood security meeting. This paper proposes an Internet of Things (IoT) based system for alerting residents in a neighbourhood as well as reporting the actual location of a particular neighbour in distress. To achieve this, a hardware system based on NodeMCU with built-in Wi-Fi chip for internet routing is designed. Communication is established remotely between the hardware system and the cloud through the server Application Programming Interface (API) that utilizes cloud resources such as Short Message Service (SMS) gateway and Google map API to craft SMS and fetch location coordinate from Google map Uniform Resource Location (URL) respectively. This piece of information is then displayed on the Liquid Crystal Display (LCD) device on users’ machine and mobile phones in real time for notification. The test carried out shows that the developed system is reliable and affordable for use in a neighbourhood.

High Performance Liquid Chromatography with Size Exclusion Column (HPLC-SEC) Method for Identifying the Major Whey Proteins of Whey Protein Products

This study was carried-out: a) to develop a high-performance liquid chromatography with size exclusion column (HPLC-SEC) method for the identification of the major whey proteins from selected whey protein products; and b) use the method to estimate the relative composition of the major whey proteins in different whey protein products.
 An HPLC Shimadzu (LC-10AD VP liquid chromatograph) with system controller (SCL-10A VP) equipped with a pump and auto-injector (SIL-10AD VP) and UV-vis detector (SPD-10AV) was used in the identification of whey proteins in standards and whey protein products. The size exclusion column (SEC) was a Yarra 3 µm, SEC-3000 Column, 7.8 mm I.D. x 30 cm with a security guard.
 The HPLC-SEC method was successful in identifying the major whey proteins of the different whey protein products.
 The β-LG contents had the highest level among the whey proteins for all the whey protein products studied, followed by the α-LA and then IgG in both WPC products. However, the α-LA and IgG of the Procream product had almost the same level which was probably due to a different process used in WPC
 All the major whey proteins with the highest pump flowrate had the shortest elution times while the whey proteins with the lowest pump flowrate had the longest elution times. The optimal pump flowrate was 0.75 mL/min since it gave a faster analysis but differentiate the peaks of the different major whey proteins.

Determination of Valbenazine related substances by liquid chromatography method complying with the current regulatory guidelines. Method robustness evaluation by Design of Experiments software

AbstractA simple, specific, rapid, sensitive reversed‐phase high‐performance liquid chromatography method was developed and validated for the determination of Valbenazine, impurities, and its degradation products. The proposed high‐performance liquid chromatography method showed optimum separation in 60 min using potassium dihydrogen phosphate buffer and ACN in the ratio of 90:10 (V/V) as mobile phase‐A whereas ACN and methanol in the ratio of 60:40 (V/V) as mobile phase‐B. YMC‐Pack ODS‐AQ (150 × 4.6 mm, 3.0 μm), column used along with security guard cartridge C18, (4.0 × 3.0 mm) at 1.1 ml/min flow. The injection volume was 10 μl and detection was carried out at 285 nm. The drug was degraded under different stress conditions and the method was validated as per International Conference on Harmonization guidelines on the basis of accuracy, precision, linearity, and robustness. A degradation study indicates that Valbenazine is prone to oxidative degradation. The method was linear over the concentration range of limit of quantitation to 200% for impurities and drug substances. The method was found robust and was studied by the design of experiments. The proposed method is applicable for the determination of the stability of Valibenazine and was successfully used in the quality control of bulk drug manufacturing and pharmaceuticals.

A Meta-Classification Model for Optimized ZBot Malware Prediction Using Learning Algorithms

Botnets pose a real threat to cybersecurity by facilitating criminal activities like malware distribution, attacks involving distributed denial of service, fraud, click fraud, phishing, and theft identification. The methods currently used for botnet detection are only appropriate for specific botnet commands and control protocols; they do not endorse botnet identification in early phases. Security guards have used honeypots successfully in several computer security defence systems. Honeypots are frequently utilised in botnet defence because they can draw botnet compromises, reveal spies in botnet membership, and deter attacker behaviour. Attackers who build and maintain botnets must devise ways to avoid honeypot traps. Machine learning methods support identification and inhibit bot threats to address the problems associated with botnet attacks. To choose the best features to feed as input to the machine learning classifiers to estimate the performance of botnet detection, a Kernel-based Ensemble Meta Classifier (KEMC) Strategy is suggested in this work. And particle swarm optimization (PSO) and genetic algorithm (GA) intelligent optimization algorithms are used to establish the ideal order. The model covered in this paper is employed to forecast Internet cyber security circumstances. The Binary Cross-Entropy (loss), the GA-PSO optimizer, the Softsign activation functions and ensembles were used in the experiment to produce the best results. The model succeeded because Forfileless malware, gathered from well-known datasets, achieved a total accuracy of 93.3% with a True Positive (TP) Range of 87.45% at zero False Positive (FP).

Smart Anti-Burglary Surveillance System using Image AI

In today's world, with an increasing number of robberies, looting and shoplifting, it is indispensable to ensure the safety of our belongings and valuables. When it comes to certain places like bank vaults, uninhabited houses, business establishments like retail shops, jewellery stores, watch stores, etc., surveillance for observing the premise is very essential and has become the unavoidable need of the hour. At such places, it is unlikely to continuously monitor the venue using conventional cameras or a security guard person. To address such type of issues which involve uncertainty of safety, our project proposes a system which will tirelessly monitor the venue at required hours, intimate the intended person (administrator) via mobile communication (Short Message Service), initiate an alert alarm at the premise in order to aware the surroundings and also save the intrusion detected frames in the specified choice of storage. Also, it is developed in such a manner that the system recognizes and does not initiate alert/notification for persons those who are reliable and trustworthy (such as the shopkeeper, habitant of the house, etc.). This system is implemented with specific considerations using Image AI and Tensor flow built upon Convolutional Neural Networks, remotely operatable by users, without compromising the importance of security and protection.

Mobile and Web-Based Security Guard Patrolling, Monitoring and Reporting System to Maintain Safe and Secure Environment at Premises

The guard tour system helps companies and organizations to monitor their security activities such as protecting people, buildings, assets, or equipment. According to the existing system, the patrolling at each checkpoint is being executed by using RFID-based digital data loggers that records and save all patrolling entries internally. The data will be transferred manually by the guard once the patrolling is completed. In some cases, when there is a problem with the device, the system unable to retrieve the patrolling data that has been already stored in the device. In addition, the current system also not be able to track the guard’s movement, patrolling information, and incidents in real-time basis. The developed Security Guard Patrolling, Monitoring and Reporting (eSmartGuard) system is able incorporates many unique and intelligent technologies such as NFC, GPS and IoT to records and save the patrolling data automatically on the cloud/server in real-time basis. An important value-added feature of the system is real-time incidents notification that able to notify any risk of the guards instantly to the in-charged security officer. Furthermore, through the eSmartGuard, the patrolling information such as time, date, GPS coordinate, guard ID can be monitored and retrieved remotely via proposed Mobile Apps and Web at a convenient time. The eSmartGuard patrolling system is proposed to improve the safety of the people and assets by assisting the security guards to perform their patrolling duty efficiently.

A systematic characterization of soil/dust ingestion for typical subpopulations in China.

An accurate assessment of human exposure to pollutants through the ingestion of dust and/or soil particles depends on a thorough understanding their rate of human ingestion. To this end, we investigated the load and size distribution patterns of dust/soil particles on the hands of three typical subpopulations, including preschoolers, college students, and security guards (outdoor workers). The geometric mean diameter of dust/soil particles on hands was observed to be 38.7 ± 11.2, 40.0 ± 12.1, and 36.8 ± 10.4μm for preschoolers, college students, and security guards, respectively. The particle size distribution differed between subpopulations: Preschoolers were more exposed to fine particles, whereas security guards were exposed to more coarse particles. The geometric means of dust/soil particle loading on the hands were 0.126, 0.0163, and 0.0377mg/cm2 for preschoolers, college students, and security guards, respectively. Males had statistically higher dust/soil particle loadings on hands than females, notably for preschoolers and college students; preschoolers with frequent hand contact with the bare ground had higher dust/soil particle loadings compared to those of peers in contact with commercial and residential grounds. The mean total dust/soil particle ingestion rate was estimated to be 245, 19.7, and 33.1mg/day for preschoolers, college students, and security guards, respectively. Our estimates for college students and security guards are close to the consensus central-tendency values recommended by the U.S. EPA's Exposure Factor Handbook for American adults, whereas the estimates for children are much higher than the upper percentile values recommended for American children.
