A Survey of Joint Security-Safety for Function, Information and Human in Industry 5.0

Industry 5.0 blows the whistle on a new industrial revolution, aiming to refocus industrial development by reintegrating the human factor into the technological equation. On the eve of the revolution, the comprehensive surveys for Industry 5.0 would provide important support for future development. However, current surveys for Industry 5.0 are still in their infancy and some gaps remain. (i) Current work lacks a comprehensive technical architecture for Industry 5.0 and an in-depth analysis of the enabling technologies that will drive Industry 5.0; (ii) There is no comprehensive survey on security issues of Industry 5.0, which will directly hinder its development; (iii) As Industry 5.0 introduces people into the technological equation, then it will also further consider the broader human interests in its security equation. It is an open issue that traditional security classifications cannot summarize these new security threats in Industry 5.0. Therefore, this survey starts by reviewing the latest key enabling technologies and proposing an overall technology hierarchical structure for Industry 5.0. Second, we investigate the triad of security issues in Industry 5.0, which includes threats and countermeasures for functional safety, information security, and humanized security. Among them, we define the third security issue in Industry 5.0, humanized security, which includes safeguarding the broader interests and rights of individuals, machines, and society. Finally, we summarize future challenges and research trends. To the best of our knowledge, this is the first comprehensive overview of security in Industry 5.0, in which humanized security is defined for the first time.

Predicting Physical Violence Against Corrections Officers Across Three Levels of Severity Using Individual and Environmental Characteristics.

Working in prisons can be a challenging job, managing a population of incarcerated people while keeping oneself, one's colleagues, and the people themselves safe. Some corrections officers may expect violence in the workplace, yet being a victim of violence is no trivial experience. In prison, violent incidents are categorized according to the severity of the violence perpetrated. However, we do not know how characteristics of a violent incident may contribute to the severity of violence perpetrated toward corrections staff. To begin to address this gap, we examined characteristics of physical assault incidents in New Zealand prisons between 2016 and 2020, in which the perpetrator of the incident was a male prisoner and the victim was a corrections officer. We examined the prediction of incidents across three levels of severity using individual and environmental characteristics. Perpetrators of serious violence tended to be already segregated from the general population at the time of the assault. We also found that perpetrators of assault against staff were different from the general prison population: prisoners who assaulted staff were more likely to be younger, gang affiliated, and had higher security classifications compared to prisoners who did not assault staff. Research suggests that characteristics of perpetrators can contribute to their risk of perpetrating violence; we found that characteristics of perpetrators (i.e., being segregated) can also contribute to the severity of violence perpetrated. Furthermore, we offer a direct comparison between prisoners who assaulted staff and prisoners who did not, therefore cementing research that prisoners who assaulted staff are different from the rest of the prison population.

Gestational Diabetes Significantly Associated With Food Insecurity and Insurance Status in the United States [ID 2683536

INTRODUCTION: Gestational diabetes (GD) is on the rise in the United States, posing risks to women's cardiovascular health, pregnancy, and their offspring's well-being. We sought to characterize the association between food insecurity and health care access and GD prevalence. METHODS: We analyzed data from 29,732 females aged 18+ in the 2021–2022 National Health Interview Survey to determine the prevalence of self-reported GD and its relationship with food security and health insurance status. We used χ2 tests to compare GD rates across different food security classifications and insurance statuses. Additionally, we cross-examined GD rates within food security groups based on insurance coverage. RESULTS: The overall GD prevalence among females was 5.70%. Stratified by food security, significant differences emerged (P<.05): 5.23% for high security, 7.99% for marginal security, 7.72% for low security, and 11.85% for very low security. We observed significant differences in GD rates by insurance coverage (P<.05): 5.57% for insured and 7.72% for uninsured respondents. Notably, when individuals were not highly food secure, there was no significant difference in the prevalence of GD between those who were insured or uninsured. CONCLUSION: This study highlights the significant associations between food insecurity, insurance coverage, and GD prevalence, although our cross-sectional analysis indicated that food insecurity may be the more salient factor. To combat GD's rise, policies should prioritize providing nutritious food access to pregnant women, potentially through mobile food units. Further research should explore whether food insecurity causally affects GD.

Open Information and Exceptions Policy of the Natural History Museum, London

There have been few, if any, open data and information management policies openly published from natural science collections. This paper contextualises the rationale for publishing the Open Information and Exceptions Policy of the Natural History Museum, London and provides the policy itself. The policy outlines how the Natural History Museum puts the principle of 'open by default' into practice; and includes sections on purpose and scope, relationship to relevant legislation (which always takes precedence over the policy), the categories of possible exceptions to open information release, what happens when exceptions are declared, relations to UK government information security classifications and definition of terms.

Reducing complexity in cyber security architecture: A practical model for security classifications

Building and running cyber security in both worlds, modern cloud security in combination with legacy on premises, introduces extra complexity. Some of the well-known security patterns and models are not applicable in cloud systems, while modern security models like zero trust (ZT) barely fit into legacy systems. Security technologies and tools are the subject of constant enhancements and adaptions to their environment. They can make security decisions on a very fine-grained basis. The corresponding rule sets and policies are becoming more and more decentralised, detailed and complex. Introducing modern security models such as ZT or micro-perimeter enforces the effect. The overall situation makes it hard for the responsible person to control the cyber security situation and the staff operating cyber security systems and technologies. Both are overwhelmed by the mass of fine-grained, fragmented and distributed security workloads. This paper introduces a practical model for security classifications in cyber security environments. The main goal of the model is to reduce complexity and keep cyber environments manageable. The model delivers not only a cyber risk classification regarding a single business application but works as an integrated view over risks for complete cyber environments.

The information needs and practices of Australian adult prisoners

This paper describes the findings of a research project conducted in six adult prisons in New South Wales, Australia that sought to study the information needs and information seeking practices of adult Australian prisoners. Through data gathered from 106 prisoner surveys, the paper identifies the information needs of Australian adult prisoners across six information domains: legal, education, spirituality, health, prison life, and re-integration. For each information domain, participants were asked to identify their preferred source or sources of information from eight possible information sources: prison libraries, tablet devices, staff, family/friends, health services, television/radio, books etc. not from the prison library, or other. The number and nature of unmet information needs are also explored and described. The data gathered enables a study of the different information needs and behaviours of female and male prisoners, and prisoners from across various security levels. The paper finds a significant level of unmet information need in the lives of Australian adult prisoners across all information domains studied. Prisoners are heavily reliant on sources of information that are likely to be non-expert such as custodial staff, other inmates, and family and friends to attempt to meet their information needs about significant critical issues such as their ongoing legal matters and their health. The information needs are similar for female and male prisoners, however their information seeking practices differ, with male prisoners being more likely to have support from family and friends as information sources than female prisoners. Prisoners living in minimum security prisons are least likely to identify a need for spirituality-related information compared with prisoners living in other security classifications and are most likely to seek information regarding their reintegration back into their communities as they plan for their release.

Compositional noninterference on hardware weak memory models

Weak memory models are employed by all modern multicore processors to improve their performance. For most code, the effects of such memory models can be largely ignored by the programmer. However, for low-level operating system or library code which can include data races for efficiency, these effects may lead to information leaks which cannot be detected without taking the specific memory model into account. While there have been some efforts to develop information flow logics which can detect such leaks, the existing approaches are either not compositional, hindering scalability, or support only a limited form of compositionality, reducing applicability to programs with only simple interactions between threads. This paper is the first to provide a compositional logic for enforcing noninterference properties on more complex concurrent algorithms, while taking into account the underlying hardware memory model. It uses rely/guarantee reasoning to establish how security classifications may be modified by concurrent threads, and considers effects of out-of-order execution allowed on modern multicore processors. The results have been formalised and proved sound in the Isabelle/HOL theorem prover, and automated in a prototype symbolic execution tool. • Weak memory models can invalidate rely/guarantee reasoning. • Structured rely/guarantees with additional checks can support general reasoning. • Rely/guarantee reasoning supports compositional information flow analysis.

Making an ‘ASH’ out of Gladue: The Bowden Experiment

The Gladue requirements have been an active element of the criminal law in Canada for over two decades, yet Indigenous incarceration rates have continued to rise precipitously and established approaches to risk management in sentencing and corrections have relegated many Indigenous offenders to longer sentences served predominantly in higher security institutions. In 2006, Correctional Service Canada “incorporated the spirit and intent of Gladue [into] case management practices both in the institutions and in the community,” stressing that Gladue provided ‘direction’ and that Indigenous “social history must be taken into consideration in developing policies and in decision-making impacting on the individual offender.” This paper analyzes CSC’s adoption of Gladue principles in its practices, focussing on the use of the ‘Aboriginal Social History’ and its impacts on Indigenous case management, especially with regard to security classifications and overrides. A comparison of Gladue reports and Aboriginal Social Histories informs of the troubles in the trickle-down from Gladue principles to practice in CSC.

Treatment of opioid dependence with depot buprenorphine (CAM2038) in custodial settings.

Background and aimsOpioid agonist treatment is effective but resource intensive to administer safely in custodial settings, leading to significant under‐treatment of opioid dependence in these settings world‐wide. This study assessed the safety of subcutaneous slow‐release depot buprenorphine in custody.DesignOpen‐label, non‐randomized trial.SettingCorrectional centres in New South Wales, Australia.ParticipantsSixty‐seven men and women, aged ≥ 18 years of various security classifications with a diagnosis of moderate to severe DSM‐5 opioid use disorder currently serving a custodial sentence of ≥ 6 months were recruited between November 2018 and July 2019. Patients not in opioid agonist treatment at recruitment commenced depot buprenorphine; patients already stable on oral methadone treatment were recruited to the comparison arm.Intervention and comparatorDepot buprenorphine (CAM2038 weekly for 4 weeks then monthly) and daily oral methadone.MeasurementsSafety was assessed by adverse event (AE) monitoring and physical examinations at every visit. Participants were administered a survey assessing self‐reported diversion and substance use at baseline and weeks 4 and 16.FindingsRetention in depot buprenorphine treatment was 92.3%. Ninety‐four per cent of patients reported at least one adverse event, typically mild and transient. No diversion was identified. The prevalence of self‐reported non‐prescribed opioid use among depot buprenorphine patients decreased significantly between baseline (97%) and week 16 (12%, odds ratio = 0.0035, 95% confidence interval = 0.0007–0.018, P < 0.0001).ConclusionsThis first study of depot buprenorphine in custodial settings showed treatment retention and outcomes comparable to those observed in community settings and for other opioid agonist treatment used in custodial settings, without increased risk of diversion.

Contact Less High Speed Data Transfer using Light

The project we are going to take-up is "Contact Less High Speed Data Transfer using Light". The purpose of this device is to provide an air gap between systems in different security classifications while transferring data between them. This enables data sharing without worrying about the network/bluetooth/wireless protocols that have been found to be vulnerable. These devices can be used in line of sight areas. The challenges would be to provide data throughputs of the rate of Mbps as these LEDs or Lasers work only at Kbps speeds and also to preserve the integrity of the data transferred. Light is omni present and hence prevention of interference from other light emitting devices would be another challenge. Though LiFi has been talked about almost about 5 years back, there is no robust system in place to provide such systems in a practical environment.

From Incarceration to Reintegration: Using the Human Services Model to Manage Canadian Prisoner Mental Health.

The effective delivery of mental health services in Canadian institutional settings has traditionally posed a challenge to the criminal justice system. Ineffective treatment options and methods of program delivery, inaccurate assessments and security classifications, the conditions in which prisoners live, restricted access to mental health professionals, high levels of individual strain, fragmented service administration, and a lack of continuity of care during the transition back to the community have all been found to have a significant negative impact on inmate mental health. The purpose of this paper is to review, and critique, the current literature on Canadian institutional mental health care and, based on this literature, make suggestions on how to improve the current system.

Security and Privacy Implications on Database Systems in Big Data Era: A Survey

For over many decades, relational database model has been considered as the leading model for data storage and management. However, as the Big Data explosion has generated a large volume of data, alternative models like NoSQL and NewSQL have emerged. With the advancement of communication technology, these database systems have given the potential to change the existing architecture from centralized mechanism to distributed in nature, to deploy as cloud-based solutions. Though all of these evolving technologies mostly focus on performance guarantees, it is still being a major concern how these systems can ensure the security and privacy of the information they handle. Different datastores support different types of integrated security mechanisms, however, most of the non-relational database systems have overlooked the security requirements of modern Big Data applications. This paper reviews security implementations in today's leading database models giving more emphasis on security and privacy attributes. A set of standard security mechanisms have been identified and evaluated based on different security classifications. Further, it provides a thorough review and a comprehensive analysis on maturity of security and privacy implementations in these database models along with future directions/enhancements so that data owners can decide on most appropriate datastore for their data-driven Big Data applications.

Treatment of Opioid Dependence with Depot Buprenorphine (CAM2038) in Custodial Settings Is Safe, Effective and Cost-Effective

Background: Opioid agonist treatment (OAT) is effective but resource intensive to administer safely in custodial settings, leading to significant under-treatment of opioid dependence in these settings worldwide. Methods: This open-label trial compared depot buprenorphine, CAM2038 (weekly for 4 weeks then monthly) to oral methadone ( https://www.anzctr.org.au ACTRN12618000942257). Modelled treatment costs included a comparison group on sublingual buprenorphine-naloxone. Men and women, aged>18 years of various security classifications with a diagnosis of moderate to severe DSM-5 opioid use disorder and a custodial sentence of at least six months were recruited from correctional centres in New South Wales, Australia. Findings: Between November 2018 and July 2019, 67 patients not in OAT treatment at recruitment commenced depot buprenorphine. Sixty-two patients already stable on oral methadone treatment were recruited to the comparison arm. Patients treated with depot buprenorphine commonly reported at least one adverse event related to study drug (63/67, 94%), typically mild and transient. No diversion of depot buprenorphine was identified. Retention in depot buprenorphine treatment was 92%. Self-reported use of non-prescribed opioids (primarily buprenorphine-naloxone) and injecting drug use decreased significantly among depot buprenorphine patients by 16 weeks (p<0·0001). Monthly treatment costs were: $112AUD for injectable depot buprenorphine, $339AUD for oral methadone and $1,299AUD for sublingual buprenorphine-naloxone. Interpretation: The first published study to explore depot buprenorphine in custodial settings shows treatment retention, substance use and safety outcomes comparable to those observed in community settings and for other OAT used in custodial settings, without increased risk of diversion. Depot buprenorphine is a more efficient and less costly OAT delivery method requiring less health and custodial staff resources to administer. Enhanced access to depot buprenorphine should be considered for custodial settings worldwide. Trial Registration: (https://www.anzctr.org.au ACTRN12618000942257).

Government Secrecy and Security Classifications in the Context of Integrity Management in Malaysia

Secrecy in government is almost always perceived as being antithetical to accountability and transparency in the conduct of democratic government. However, it is undisputable that government secrecy is practiced the world over because it is indispensable to state security, international relations, public and personal interests. Hence, democratic governments must perform a delicate balancing act between openness and confidentiality in the handling of official information. Indeed, effective governance requires various legal regimes that control government information through security classifications and impose punishments on offenders. This paper aims to address the dearth of research on government secrecy and security classifications in the context of integrity management in Malaysia. Integrity management encompasses not only the exercise of moral values by public institutions and officials but also the integrity of processes and procedures that uphold the integrity of governance. This exploratory research uses qualitative content analysis of data gathered from official government publications and websites, relevant documents and course notes, as well as interviews and correspondence with field experts. The inferences derived from themes and categories generated have resulted in several important findings. First, the 1972 Official Secrets Act (OSA) plays a significant role as part of a plethora of statutes and ethical codes that are indispensable to upholding government integrity. Second, weaknesses in balancing between openness and confidentiality when handling official information are attributed to organizational failure, public officials’ lack of ethical values, comprehension and training. The challenge is to ensure that the OSA is not used for cover-ups of corruption, ethical misconducts and administrative transgressions while the proposed Freedom of Information Act does not lead to a culture of blaming and mistrust that could lead to the paralysis of government and governance.

Security in Telehealth Systems From a Software Engineering Viewpoint: A Systematic Mapping Study

Telehealth systems deliver remote care of elderly and physically less able patients as well as remote surgeries, treatments, and diagnoses. In this regard, several systemic properties must be satisfied (such as security) in order to ensure the functionality of Telehealth systems. Although existing studies discuss different security episodes that involve Telehealth systems, it is difficult to have a clear standpoint about which are the most reported security issues and which solutions have been proposed. Furthermore, since Telehealth systems are composed of several software systems, it is not clear which critical areas of Software Engineering are relevant to develop secure Telehealth systems. This article reports a systematic mapping study (SMS) whose purpose is to detect, organize, and characterize security issues in Telehealth systems. Based on the SMS results, we examine how Software Engineering may help to develop secure Telehealth systems. From over a thousand studies, we distinguished and classified 41 primary studies. Results show that (i) four security classifications ( attacks , vulnerabilities , weaknesses , and threats ) concentrate the most reported security issues; (ii) three security strategies ( detect attacks , stop or mitigate attacks and react to attacks ) characterize security issues, and (iii) the most relevant research themes are related to insecure data transmission and privacy. The SMS’s findings suggest that software design, requirements, and models are key areas to develop secure Telehealth systems.

From rain to famine: assessing the utility of rainfall observations and seasonal forecasts to anticipate food insecurity in East Africa

East Africa experiences chronic food insecurity, with levels varying from year-to-year across the region. Given that much can be done to prevent this level of suffering before it happens, humanitarian agencies monitor early indicators of food insecurity to trigger early action. Forecasts of total seasonal rainfall are one tool used to monitor and anticipate food security outcomes. Factors beyond rainfall, such as conflict, are key determinants of whether lack of rainfall can become a problem. In this paper, we present a quantitative analysis that isolates the value of rainfall information in anticipating food security outcomes across livelihood groups in East Africa. Comparing observed rainfall and temperature with food security classifications, we quantify how much the chance of food insecurity increases when rainfall is low. Results differed dramatically among livelihood groups; pastoralists in East Africa more frequently experience food insecurity than do non-pastoralists, and 12 months of low rainfall greatly increases the chances of “crisis” and “emergency” food security in pastoralist regions. In non-pastoralist regions, the relationship with total rainfall is not as strong. Similar results were obtained for livelihood groups in Kenya and Ethiopia, with slightly differing results in Somalia. Given this, we evaluated the relevance of monitoring and forecasting seasonal total rainfall. Our quantitative results demonstrate that six months of rainfall observations can already indicate a heightened risk of food insecurity, a full six months before conditions deteriorate. Combining rainfall observations with seasonal forecasts can further change the range of possible outcomes to indicate higher or lower risk of food insecurity, but the added value of seasonal forecasts is noticeable only when they show a strong probability of below-normal rainfall.

The prisoner’s dilemma: How male prisoners experience and respond to penal threat while incarcerated

Drawing on interview data with 56 former prisoners in Canada, we examine how male prisoners understand, experience, and respond to threat while incarcerated. We show that prisoners face a variety of different and often competing threats, resulting from prisoner interactions (e.g. threat of physical violence for being a “snitch”) on the one side, and institutional powers and procedures on the other side (e.g. threat of delayed release from prison). These threats are competing insofar as countering a prisoner threat opens the door to threat on the institutional level (i.e. administrative uncertainties) and vice versa. As a consequence, we show how feeling threatened for prisoners becomes paramount and in many cases unavoidable as the different threats in prison are difficult, if not impossible, to handle in unison. However, in an effort to stay physically safe and work toward their release, prisoners must find viable strategies to navigate different prison environments, particularly as they move between prisons of differing security classifications. We draw on Giddens' notion of “ontological insecurity” to draw attention to prisoners' feelings of perpetual vulnerability and insecurity. In addition, we build on Luhmann's conceptualization of risk and danger to explain how male prisoners experience and respond to moments of “danger” when they are faced with competing threats and must decide how to best navigate them.

‘I was trying to make my stay there more positive’: rituals and routines in Canadian prisons

Researchers have demonstrated how engaging in rituals or ‘patterned’ behaviors can help people cope with stressful situations and significant life changes. Yet, knowledge of the role of ritual and routine practices for, or how each are used by, federally incarcerated Canadian men is limited. To respond to this lacuna, we analyzed transcripts from 56 semi-structured in-depth interviews with former male federal prisoners released on parole for emergent themes related to ritual and routine practices across prisons of different security classifications. Findings reveal the effectiveness of rituals for managing and mitigating the stresses of incarceration, specifically how prisoners’ routine behaviors constitute a positive strategy of adaption to incarceration (e.g. alleviating stress and passing time), in preparation for life post-incarceration. Structural ritualization theory frames the analyses and implications presented in this study.

Privacy Information Security Classification for Internet of Things Based on Internet Data

A lot of privacy protection technologies have been proposed, but most of them are independent and aim at protecting some specific privacy. There is hardly enough deep study into the attributes of privacy. To minimize the damage and influence of the privacy disclosure, the important and sensitive privacy should be a priori preserved if all privacy pieces cannot be preserved. This paper focuses on studying the attributes of the privacy and proposes privacy information security classification (PISC) model. The privacy is classified into four security classifications by PISC, and each classification has its security goal, respectively. Google search engine is taken as the research platform to collect the related data for study. Based on the data from the search engine, we got the security classifications of 53 pieces of privacy.
