Keamanan Manusia dalam Perdagangan Manusia: Analisis Peran IOM Menangani Human Trafficking

Abstract The most crucial thing about human trafficking is that the activity does not disappear and even continues to show increasing numbers of victims. Handling cannot be carried out only by the government or by state officials but requires comprehensive handling from all levels of society. This research aims to highlight the role of an organization in dealing with these problems using a human security approach. Descriptively and qualitatively the facts are analyzed and produce several conclusions: a). efforts to help, defend, rescue based on existing laws which are more outward in nature, but also on efforts to implement human rights values ​​from within. Apart from being an ethical basis, human values ​​are also implemented in every action. b). The problem of human trafficking cannot be separated from structural dimensions such as the fulfillment of welfare, justice and development policies which influence all dimensions of human livelihood. c). The best prevention is through education, providing employment opportunities, welfare and the most important thing is to provide a sense of security for all citizens.

Two-step approach to manufacture sustainable artificial steel slag aggregate used in alkali-activated concrete

This study utilized 3 mol/L hydrochloric acid to activate steel slag powder in combination with carbonation and produced the artificial steel slag aggregate (ASSA) for the use in alkali-activated concrete. The composition, microstructure, and properties of the ASSA were investigated. The results indicated that acid activation enhanced the compressive strength of the ASSA by 26.7 %, reduced the total porosity by 5.2 %, and facilitated the formation of portlandite, C-S-H gel, and monocarbonate in the hydration products. Carbonation enhanced the compressive strength of the ASSA by 28.5 %, reduced the total porosity by 14.5 %, and led to the formation of calcite and aragonite. The effect of acid activation coupled with carbonation on the ASSA manifested in a 43.6 % enhancement in compressive strength, a 17.9 % reduction in porosity, and an expansion rate reduction to 1.2 %. The alkali-activated concrete produced with the modified ASSA exhibited enhanced compressive strength by up to 21 % compared with the control group, facilitated internal curing to balance internal humidity, and mitigated drying shrinkage deformation. This study provides a viable and secure approach to the reutilization of steel slag.

Optimal location design for multiple Far-UVC lamps to enhance indoor bioaerosol disinfection by CFD-based Bayesian optimization

In occupied indoor environments, 222 nm far-UVC is a secure and effective approach for controlling the spread of infectious bioaerosols. To enhance the disinfection effectiveness, it is crucial to carefully design the placement of far-UVC lamps, by considering the impact of airflow pattern, bioaerosol distribution, and irradiance exposure. Using CFD alone for designing the locations of multiple lamps presents challenges due to the high computational cost resulting from the high number of potential combinations. Therefore, this study combined CFD with the Bayesian optimization method to improve the computational efficiency, enabling customized design for complex scenarios. The proposed method was first validated with experimental data and the results from the grid search method. Next, the validated method was applied to design the placement of multiple far-UVC lamps in a railway compartment. In the studied railway compartment, just 1 h of optimization led to 1.05-fold–2.87-fold improvement in bioaerosol disinfection efficiency compared to random selection and uniform distribution. This optimization method for customized location design can maximize the utilization of far-UVC lamps, reducing equipment investment and energy consumption while ensuring effective disinfection.

A deep experimental analysis of energy‐proficient firewall policies and security practices for resource limited wireless networks

AbstractThe role of firewalls and security principles in resource‐limited wireless networks and Wireless Sensor Networks (WSN) is more expected than in any dedicated network environment. The advanced wireless technologies and emerging fashion of autonomous wireless network nodes are mostly expecting resilient firewall services with multi‐level security policies. Wireless networks are classified under sensor networks, Internet of Things (IoT) mobile networks, and so forth. According to the expectations, security frameworks are gradually invented around the communication platform using various ideologies. The novel ideology and respective implementation effort open better solutions against wireless network attacks. Anyhow, the minimal production of time complexity, energy complexity, and computation overhead from any novel security approach is always considered under the best practices. The complexity levels directly affect the wireless node's energy consumption ability and operational spans severely. The energy optimization techniques and load‐balancing techniques integrated into multi‐class firewall rules are extremely useful solutions for resource‐limited wireless networks. This article has been motivated to analyze the recent firewall techniques and secure data communication mechanisms used for securing wireless networks. Consequently, the practice of comparative literature analysis helps to improve the current limitations identified under the classified categories of security mechanisms such as energy‐optimized security principles and load‐balanced security principles. The establishment of secure and energy‐optimized multi‐class firewall rules in each wireless node assures a healthy focus on next‐generation networks. The experiment section shows the benefits of energy‐optimized secure network communication in terms of better accuracy and the benefits of load‐balanced secure network communication through minimal overhead in computing platforms.

TVRAVNF: an efficient low-cost TEE-based virtual remote attestation scheme for virtual network functions

With the continuous advancement of virtualization technology and the widespread adoption of 5G networks, the application of the Network Function Virtualization (NFV) architecture has become increasingly popular and prevalent. While the NFV architecture brings a lot of advantages, it also introduces security challenges, including the effective and efficient verification of the integrity of deployed Virtual Network Functions (VNFs) and ensuring the secure operation of VNFs. To address the challenge of efficiently conducting virtual remote attestation for VNFs and establishing trust in virtualized environments like NFV architecture, we propose TVRAVNF, which is a highly efficient and low-cost TEE-based virtual remote attestation scheme for VNFs. The scheme we proposed ensures the security and effectiveness of the virtual remote attestation process by leveraging TEE. Furthermore, we introduces a novel local attestation mechanism, which not only reduces the overall overhead of the virtual remote attestation process but also shortens the attestation interval to mitigate Time-Of-Check-Time-Of-Use attacks, thereby enhancing overall security. We conduct experiments to validate the overhead of the TVRAVNF scheme and compare its performance with that of a typical remote attestation process within a maximum unattested time interval. The experimental results demonstrate that, by employing the local attestation mechanism, our solution achieves nearly an 80% significant performance improvement with a relatively small time overhead for small to medium-sized files. This further substantiates the significant advantages of our approach in both security and efficiency.

Atmosphere, imminence and the Manchester Arena Inquiry: on the affective modalities of becoming situationally aware to urban terrorism

ABSTRACT Building situational awareness has become a central logic among contemporary security apparatuses for abating no-warning urban terrorism. Situational awareness, we contend, casts the sensory, perceptual and affective capacities of human bodies to decipher their immediate surroundings and attune to the non-representational and more-than-known of an enfolding situation, as essential to its execution. What modalities of sense-making and attunement, then, does this burgeoning security rationality demand? And what sensibilities, affectivities and subjectivities are (re)produced and legitimated across urban life? In this paper, we unpack these questions by examining the ways affective and atmospheric attunement(s) are infused within orthodox and emergent security approaches for developing and honing situational awareness. We argue that affective atmospheres in particular furnish the theoretical architecture for attending to the spatio-affective-material registers through which imminence becomes palpable. Empirically, by analysing the Public Inquiry following the 2017 Manchester Arena attack, we elucidate where the Inquiry advanced discussions on (the limits of) situational awareness and its sensorial, affective and atmospheric dimensions, thereby extending situational awareness into an atmospheric agenda within urban geopolitics. Finally, we reflect on how the impending UK Protect Duty might reconfigure the legal landscape of situational awareness, city resilience, and the affective economies of (in)attention.

Research on ZKP Algorithm of Data Asset Security and Privacy Protection Based on Blockchain Technology

Zero Knowledge Proof (ZKP) is a very effective method of preserving privacy as it hides the most confidential information throughout the transaction. In this paper, we present a security and privacy-preserving approach for blockchain that relies on account and multi-data asset models using the Zero Knowledge Proof (ZKP) mechanism. We provide options for transferring data assets and detecting duplicate expenditures, and we also develop transaction structures, anonymised addresses and anonymised metadata for the data assets. To create and validate the ZKP, we use the zk-SNARKs algorithm and specify validation criteria for masked transactions, and finally conduct experimental tests to validate it. Creating better algorithms for ZKP will be the focus of our future efforts.

Backdoor-resistant certificateless-based message-locked integrity auditing for computing power network

With the evolution of 6G technology, the computing power network (CPN), a crucial infrastructure underpinning the future of digital transformation, is being tightly integrated with 6G to jointly foster significant enhancements in network performance. However, the openness of the network and the semi-trusted nature of cloud service providers pose risks to user data, including potential theft and tampering. To address these challenges, this paper introduces a novel scheme called the backdoor-resistant certificateless message-locked integrity audit (BRCLMIA). This scheme incorporates a cryptographic reverse firewall, offering an efficient and secure approach to auditing CPN data integrity. Our thorough analysis demonstrates that the BRCLMIA scheme effectively safeguards against existential forgery under adaptive message attacks, safeguards against algorithm replacement attacks, and ensures the integrity and authenticity of data transmitted within the CPN. Furthermore, the performance analysis reveals that the BRCLMIA scheme exhibits remarkable communication and computational efficiency while defending against various attacks.

Disaster, risk and conducting human security research in Southeast Asia

PurposeTyphoons, storm surges and sea-level rise pose major risks to life and livelihoods in Southeast Asia and demand state-level action. However, the prominence and frequency of these symptomatic disasters often divert attention from underlying systemic and situational issues. The purpose of this paper is a normative and conceptual one. It makes the case for a grounded and disaggregated human security approach for decoding complex relationships of risk, power, politics, inequality and mistrust that underpin problems we seek to address.Design/methodology/approachThis paper’s approach situates the emergence of the human security paradigm and its connections to human development, sustainable economic growth and rights-based protections in historical context. It then draws on observations across the region over a number of years combined with a review of relevant research to detail how the vulnerability and exposure to disaster of at-risk communities extend beyond random or natural events. Having established that a focus on the immediate characteristics of disaster limits our frames of reference and the utility of subsequent responses, it proceeds to analyse the political, environmental and economic drivers amplifying exposure to disaster in Southeast Asia.FindingsThe findings reveal that the vulnerability and insecurity experienced by at-risk communities are not wholly random or exclusively the result of natural, unavoidable events. Exposure to disasters is also shaped by various situational factors, including habitat loss, dispossession, displacement, marginalisation and limited opportunities. Incorporating a more holistic human security perspective can bring into focus the less visible forces and interests that amplify vulnerability to hazard risk for affected individuals and communities in the region.Originality/valueThis is an original paper that underscores the conceptual and methodological importance of a grounded and disaggregated human security approach to grasp the disaster-prone territories of risk in contemporary Southeast Asia and for advancing appropriate responses.

Blood-Derived Extracellular Vesicles as a Promising Liquid Biopsy Diagnostic Tool for Early Cancer Detection.

Cancer poses a significant public health challenge worldwide, and timely screening has the potential to mitigate cancer progression and reduce mortality rates. Currently, early identification of most tumors relies on imaging techniques and tissue biopsies. However, the use of low-cost, highly sensitive, non-invasive detection methods for early cancer screening has become more attractive. Extracellular Vesicles (EVs) released by all living cells contain distinctive biological components, such as nucleic acids, proteins, and lipids. These vesicles play crucial roles in the tumor microenvironment and intercellular communication during tumor progression, rendering liquid biopsy a particularly suitable method for diagnosis. Nevertheless, challenges related to purification methods and validation of efficacy currently hinder its widespread clinical implementation. These limitations underscore the importance of refining isolation techniques and conducting comprehensive investigations on EVs. This study seeks to evaluate the potential of liquid biopsy utilizing blood-derived EVs as a practical, cost-effective, and secure approach for early cancer detection.

New quantum color image watermarking technique (NQCIWT)

The crazy, unconscious use of the Internet, and the increase in cybercrime and hacking, which resulted in the loss of a large number of sensitive data, the risk of piracy, etc. were the motivation for protecting rights, securing and hiding essential information such as images, audio, etc. Watermarking was a popular security, copyright and privacy approach and one of the problems in modern quantum digital computing that produced more powerful quantum protection techniques than the classical one that used classical techniques such as digital wavelet transformation and Hungarian algorithms. Recent advances in quantum image representation and processing help to manipulate data hidden. This paper proposes a new watermark technique in which a color watermark image is hidden within another color-carrying image after transformation into the quantum domain using the recently completed quantum color image representation technique. Finally, a comparison is made between the proposed method and the most recent watermarking techniques is establish in terms of PSNR (peak signal-to-noise ratio), which shows the high precision of the proposed technique and improves the imperceptibility compared to the related schemes.
