Fulltext Priority Queue Based Reactive Buffer Management Policy for Delay Tolerant Network under City Based Environments

Ayub Q, Ngadi A, Rashid S, Habib HA

PLoS One, 2018;13(2):e0191580.
PMID: 29438438 DOI: 10.1371/journal.pone.0191580

Delay Tolerant Network (DTN) multi-copy routing protocols are privileged to create and transmit multiple copies of each message that causes congestion and some messages are dropped. This process is known as reactive drop because messages were dropped re-actively to overcome buffer overflows. The existing reactive buffer management policies apply a single metric to drop source, relay and destine messages. Hereby, selection to drop a message is dubious because each message as source, relay or destine may have consumed dissimilar magnitude of network resources. Similarly, DTN has included time to live (ttl) parameter which defines lifetime of message. Hence, when ttl expires then message is automatically destroyed from relay nodes. However, time-to-live (ttl) is not applicable on messages reached at their destinations. Moreover, nodes keep replicating messages till ttl expires even-though large number of messages has already been dispersed. In this paper, we have proposed Priority Queue Based Reactive Buffer Management Policy (PQB-R) for DTN under City Based Environments. The PQB-R classifies buffered messages into source, relay and destine queues. Moreover, separate drop metric has been applied on individual queue. The experiment results prove that proposed PQB-R has reduced number of messages transmissions, message drop and increases delivery ratio.

Introduction: With an increase in national nursing shortage, organizational commitment is extremely
important for retention of nurses. This predictive study determines the level of organizational commitment and the predictive ability of perceived organizational support, components of job satisfaction, including pay, task requirement, organizational policies, autonomy, interaction and professional status as well as years of experience on organizational commitment. Method: Data were collected from 416 nurses in four state hospitals in Malaysia, using self-administered questionnaires. The hospitals were selected from each region in Peninsular Malaysia and samples were selected by a random sampling method. Questionnaires, including demographic data, Organizational Commitment Questionnaires, Survey of Perceived Organizational Support,and Index Work Satisfaction were distributed by researcher and research assistants. Stepwise multiple regression technique was used to analyze the data. Results: The results discovered that (1) nearly half of the subjects (48.07%) reported high level of organizational commitment. (2) Professional status, autonomy, interaction, task requirement and years of experience could predict the organizational commitment (ß = 0.52, 0.17, p < 0.01); ß= 0.13, 0.11, 0.09, p < 0.05 respectively). Overall, all predictors explained 33% of variability
in the organizational commitment among nurses in state hospitals. Conclusions: This study found that nurses in state hospitals were highly committed to their organizations. Results of this study provide information for nurse administrators to consider and maintain these factors in nursing practice to foster a high level of organizational commitment among Malaysian nurses.

Hari Krishnan, T.

Journal of Occupational Safety and Health, 2012;9(3):17-22.
MyJurnal

Introductions: Call center has been defined as a working environment in which uses telephone and computer for the purpose of marketing and manage communication with prospect clients or existing clients (Rocha, Glina, Morinho and Nakasato, 2005; Sprigg, Smith and Jackson, 2003).
Methodology: The study was conducted via observation of working condition and face to face interview with call center operators. Measurement of anthropometrics was also conducted.
Results: Ergonomics issues found at call center were inappropriate work condition and workstation which lead to awkward sitting posture (sitting with forward leaning posture, raised shoulder, feet not supported on floor). Besides that organizational policy which required high job demand and subsequently lead to prolonged sitting and static posture (very minimal posture changes). Combination all these factors lead to musculoskeletal symptoms and the operators reported of having neck, shoulder, upper back and lower back pain compared to other body parts.
Conclusion: The management should embark on organization wide ergonomics management program and should review the current policy and create safe and healthy working environment by providing suitable workstation for the operators in order to prevent musculoskeletal.

Tabah A, Elhadi M, Ballard E, Cortegiani A, Cecconi M, Unoki T, et al.

J Crit Care, 2022 Oct;71:154050.
PMID: 35525226 DOI: 10.1016/j.jcrc.2022.154050

BACKGROUND: During the COVID-19 pandemic, intensive care units (ICU) introduced restrictions to in-person family visiting to safeguard patients, healthcare personnel, and visitors.
METHODS: We conducted a web-based survey (March-July 2021) investigating ICU visiting practices before the pandemic, at peak COVID-19 ICU admissions, and at the time of survey response. We sought data on visiting policies and communication modes including use of virtual visiting (videoconferencing).
RESULTS: We obtained 667 valid responses representing ICUs in all continents. Before the pandemic, 20% (106/525) had unrestricted visiting hours; 6% (30/525) did not allow in-person visiting. At peak, 84% (558/667) did not allow in-person visiting for patients with COVID-19; 66% for patients without COVID-19. This proportion had decreased to 55% (369/667) at time of survey reporting. A government mandate to restrict hospital visiting was reported by 53% (354/646). Most ICUs (55%, 353/615) used regular telephone updates; 50% (306/667) used telephone for formal meetings and discussions regarding prognosis or end-of-life. Virtual visiting was available in 63% (418/667) at time of survey.
CONCLUSIONS: Highly restrictive visiting policies were introduced at the initial pandemic peaks, were subsequently liberalized, but without returning to pre-pandemic practices. Telephone became the primary communication mode in most ICUs, supplemented with virtual visits.

Female genital mutilation. Council on Scientific Affairs, American Medical Association

JAMA, 1995 Dec 6;274(21):1714-6.
PMID: 7474278

Female genital mutilation is the medically unnecessary modification of female genitalia. Female genital mutilation typically occurs at about 7 years of age, but mutilated women suffer severe medical complications throughout their adult lives. Female genital mutilation most frequently occurs in Africa, the Middle East, and Muslim parts of Indonesia and Malaysia, and it is generally part of a ceremonial induction into adult society. Recent political and economic problems in these regions, however, have increased the numbers of students and refugees to the United States. Consequently, US physicians are treating an increasing number of mutilated patients. The Council on Scientific Affairs recommends that US physicians join the World Health Organization, the World Medical Association, and other major health care organizations in opposing all forms of medically unnecessary surgical modification of the female genitalia.

Swee, W.F., Anza, E., Noor Hassim, I.

Medicine & Health, 2007;2(1):93-98.
MyJurnal

A cross sectional study on work stress prevalence was carried out among 185 executives and managers in the head quarter of an international tobacco company. The aim of the study was to identify work stress prevalence in this company and work stressors that were associated with stress experienced by the workers. A questionnaire based on the Personal Stress Inventory by O'Donell (1984) was used. Data collected from participants included sociodemography factors, symptoms of stress and work stressors related to organizational policy, organizational structure, organizational process, and work environment. The study showed that the prevalence of stress among executives was 68.1% and managers were 67.9%. There was no significant difference in the level of stress between the executives and the managers in the company. The sociodemographic factors that were significantly associated with stress were salary, number of children and personal factors. The significant stressors in the workplace were lack of job recognition, over focusing on quality of work, heavy workload and long working hours.

Fulltext The Practice of Gastrointestinal Motility Laboratory During COVID-19 Pandemic: Position Statements of the Asian Neurogastroenterology and Motility Association (ANMA-GML-COVID-19 Position Statements)

Siah KTH, Rahman MM, Ong AML, Soh AYS, Lee YY, Xiao Y, et al.

J Neurogastroenterol Motil, 2020 07 30;26(3):299-310.
PMID: 32606253 DOI: 10.5056/jnm20107

During the Coronavirus Disease 2019 (COVID-19) pandemic, practices of gastrointestinal procedures within the digestive tract require special precautions due to the risk of contraction of severe acute respiratoy syndrome coronavirus-2 (SARS-CoV-2) infection. Many procedures in the gastrointestinal motility laboratory may be considered moderate to high-risk for viral transmission. Healthcare staff working in gastrointestinal motility laboratories are frequently exposed to splashes, air droplets, mucus, or saliva during the procedures. Moreover, some are aerosol-generating and thus have a high risk of viral transmission. There are multiple guidelines on the practices of gastrointestinal endoscopy during this pandemic. However, such guidelines are still lacking and urgently needed for the practice of gastrointestinal motility laboratories. Hence, the Asian Neurogastroenterology and Motility Association had organized a group of gastrointestinal motility experts and infectious disease specialists to produce a position statement paper based-on current available evidence and consensus opinion with aims to provide a clear guidance on the practices of gastrointestinal motility laboratories during the COVID-19 pandemic. This guideline covers a wide range of topics on gastrointestinal motility activities from scheduling a motility test, the precautions at different steps of the procedure to disinfection for the safety and well-being of the patients and the healthcare workers. These practices may vary in different countries depending on the stages of the pandemic, local or institutional policy, and the availability of healthcare resources. This guideline is useful when the transmission rate of SARS-CoV-2 is high. It may change rapidly depending on the situation of the epidemic and when new evidence becomes available.

Addressing procedural challenges of ethical review system: Towards a better ethical quality of clinical trials review in Malaysia

See HY, Mohamed MS, Mohd Noor SN, Low WY

Account Res, 2019 01;26(1):49-64.
PMID: 30526066 DOI: 10.1080/08989621.2018.1556646

The review of clinical trials with human participants in Malaysia is governed by a decentralized control system. The clinical trial protocols are reviewed by 13 registered research ethics committees (RECs) in Malaysia. A governmental body, the National Pharmaceutical Control Bureau, is responsible for the inspection and oversight of these registered RECs to ensure that they comply with the regulatory requirements. However, this study highlights that each REC in Malaysia has a different standard operating procedure and ethical review process. Other procedural challenges identified include inadequate membership, poor mechanism for research monitoring after ethical approval, and insufficient resources. Establishments of a national standard of REC and a central ethics committee are suggested to ensure procedural compliance in the oversight of clinical trials in Malaysia. While there is a growing concern that procedural compliance may not have a direct impact on the protection of human subjects, our key point is that an ethical review system compliant with the national standards could serve as a strong framework to support and enhance the ethical quality of decision-making and judgement. We believe that being aware of how influential procedural compliance can be would help committees improve the ethical quality of their research review.

Indirect effect of management support on users' compliance behaviour towards information security policies

Humaidi N, Balakrishnan V

Health Inf Manag, 2018 Jan;47(1):17-27.
PMID: 28537207 DOI: 10.1177/1833358317700255

BACKGROUND: Health information systems are innovative products designed to improve the delivery of effective healthcare, but they are also vulnerable to breaches of information security, including unauthorised access, use, disclosure, disruption, modification or destruction, and duplication of passwords. Greater openness and multi-connectedness between heterogeneous stakeholders within health networks increase the security risk.
OBJECTIVE: The focus of this research was on the indirect effects of management support (MS) on user compliance behaviour (UCB) towards information security policies (ISPs) among health professionals in selected Malaysian public hospitals. The aim was to identify significant factors and provide a clearer understanding of the nature of compliance behaviour in the health sector environment.
METHOD: Using a survey design and stratified random sampling method, self-administered questionnaires were distributed to 454 healthcare professionals in three hospitals. Drawing on theories of planned behaviour, perceived behavioural control (self-efficacy (SE) and MS components) and the trust factor, an information system security policies compliance model was developed to test three related constructs (MS, SE and perceived trust (PT)) and their relationship to UCB towards ISPs.
RESULTS: Results showed a 52.8% variation in UCB through significant factors. Partial least squares structural equation modelling demonstrated that all factors were significant and that MS had an indirect effect on UCB through both PT and SE among respondents to this study.
CONCLUSION: The research model based on the theory of planned behaviour in combination with other human and organisational factors has made a useful contribution towards explaining compliance behaviour in relation to organisational ISPs, with trust being the most significant factor. In adopting a multidimensional approach to management-user interactions via multidisciplinary concepts and theories to evaluate the association between the integrated management-user values and the nature of compliance towards ISPs among selected health professionals, this study has made a unique contribution to the literature.

A grim contradiction: the practice and consequences of corporate social responsibility by British American Tobacco in Malaysia

Barraclough S, Morrow M

Soc Sci Med, 2008 Apr;66(8):1784-96.
PMID: 18304713 DOI: 10.1016/j.socscimed.2008.01.001

In the wake of the World Health Organization Framework Convention on Tobacco Control, corporate social responsibility (CSR) is among the few remaining mechanisms for tobacco corporations publicly to promote their interests. Health advocates may be unaware of the scale, nature and implications of tobacco industry CSR. This investigation aimed to construct a typology of tobacco industry CSR through a case study of the evolution and impact of CSR activities of a particular tobacco corporation in one country - British American Tobacco, Malaysia (BATM), the Malaysian market leader. Methods included searching, compiling and critically appraising publicly available materials from British American Tobacco, BATM, published literature and other sources. The study examined BATM's CSR strategy, the issues which it raises, consequences for tobacco control and potential responses by health advocates. The investigation found that BATM's CSR activities included assistance to tobacco growers, charitable donations, scholarships, involvement in anti-smuggling measures, 'youth smoking prevention' programs and annual Social Reports. BATM has stated that its model is predominantly motivated by social and stakeholder obligations. Its CSR activities have, however, had the additional benefits of contributing to a favourable image, deflecting criticism and establishing a modus vivendi with regulators that assists BATM's continued operations and profitability. It is imperative that health advocates highlight the potential conflicts inherent in such arrangements and develop strategies to address the concerns raised.
