Fulltext Cryptanalysis and Improvement of "A Secure Password Authentication Mechanism for Seamless Handover in Proxy Mobile IPv6 Networks"

Alizadeh M, Zamani M, Baharun S, Abdul Manaf A, Sakurai K, Anada H, et al.

PLoS One, 2015;10(11):e0142716.
PMID: 26580963 DOI: 10.1371/journal.pone.0142716

Proxy Mobile IPv6 is a network-based localized mobility management protocol that supports mobility without mobile nodes' participation in mobility signaling. The details of user authentication procedure are not specified in this standard, hence, many authentication schemes have been proposed for this standard. In 2013, Chuang et al., proposed an authentication method for PMIPv6, called SPAM. However, Chuang et al.'s Scheme protects the network against some security attacks, but it is still vulnerable to impersonation and password guessing attacks. In addition, we discuss other security drawbacks such as lack of revocation procedure in case of loss or stolen device, and anonymity issues of the Chuang et al.'s scheme. We further propose an enhanced authentication method to mitigate the security issues of SPAM method and evaluate our scheme using BAN logic.

Shabbir A, Rizvi S, Alam MM, Shirazi F, Su'ud MM

PLoS One, 2024;19(2):e0296392.
PMID: 38408070 DOI: 10.1371/journal.pone.0296392

The quest for energy efficiency (EE) in multi-tier Heterogeneous Networks (HetNets) is observed within the context of surging high-speed data demands and the rapid proliferation of wireless devices. The analysis of existing literature underscores the need for more comprehensive strategies to realize genuinely energy-efficient HetNets. This research work contributes significantly by employing a systematic methodology, utilizing This model facilitates the assessment of network performance by considering the spatial distribution of network elements. The stochastic nature of the PPP allows for a realistic representation of the random spatial deployment of base stations and users in multi-tier HetNets. Additionally, an analytical framework for Quality of Service (QoS) provision based on D-DOSS simplifies the understanding of user-base station relationships and offers essential performance metrics. Moreover, an optimization problem formulation, considering coverage, energy maximization, and delay minimization constraints, aims to strike a balance between key network attributes. This research not only addresses crucial challenges in creating EE HetNets but also lays a foundation for future advancements in wireless network design, operation, and management, ultimately benefiting network operators and end-users alike amidst the growing demand for high-speed data and the increasing prevalence of wireless devices. The proposed D-DOSS approach not only offers insights for the systematic design and analysis of EE HetNets but also systematically outperforms other state-of-the-art techniques presented. The improvement in energy efficiency systematically ranges from 67% (min side) to 98% (max side), systematically demonstrating the effectiveness of the proposed strategy in achieving higher energy efficiency compared to existing strategies. This systematic research work establishes a strong foundation for the systematic evolution of energy-efficient HetNets. The systematic methodology employed ensures a comprehensive understanding of the complex interplay of network dynamics and user requirements in a multi-tiered environment.

Lexical Alignment is Pervasive Across Contexts in Non-WEIRD Adult-Child Interactions

Chieng ACJ, Wynn CJ, Wong TP, Barrett TS, Borrie SA

Cogn Sci, 2024 Mar;48(3):e13417.
PMID: 38478742 DOI: 10.1111/cogs.13417

Lexical alignment, a communication phenomenon where conversational partners adapt their word choices to become more similar, plays an important role in the development of language and social communication skills. While this has been studied extensively in the conversations of preschool-aged children and their parents in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) communities, research in other pediatric populations is sparse. This study makes significant expansions on the existing literature by focusing on alignment in naturalistic conversations of school-aged children from a non-WEIRD population across multiple conversational tasks and with different types of adult partners. Typically developing children aged 5 to 8 years (n = 45) engaged in four semi-structured conversations that differed by task (problem-solving vs. play-based) and by partner (parent vs. university student), resulting in a corpus of 180 conversations. Lexical alignment scores were calculated and compared to sham conversations, representing alignment occurring at the level of chance. Both children and adults coordinated their conversational utterances by re-using or aligning each other's word choices. This alignment behavior persisted across conversational tasks and partners, although the degree of alignment was moderated by the conversational context. These findings suggest that lexical alignment is a robust phenomenon in conversations between school-age children and adults. Furthermore, this study extends lexical alignment findings to a non-WEIRD culture, suggesting that alignment may be a coordination strategy employed by adults and children across diverse linguistic and cultural backgrounds.

Fulltext Remote Monitoring of COVID-19 Patients Using Multisensor Body Area Network Innovative System

Al-Barazanchi I, Hashim W, Ahmed Alkahtani A, Rasheed Abdulshaheed H, Muwafaq Gheni H, Murthy A, et al.

Comput Intell Neurosci, 2022;2022:9879259.
PMID: 36156952 DOI: 10.1155/2022/9879259

As of late 2019, the COVID19 pandemic has been causing huge concern around the world. Such a pandemic posed serious threats to public safety, the well-being of healthcare workers, and the overall health of the population. If automation can be implemented in healthcare systems, patients could be better cared for and health industries could be less burdened. To combat such challenges, e-health requires apps and intelligent systems. Using WBAN sensors and networks, a doctor or medical professional can advise patients on the best course of action. Patients' fitness could be assessed using WBAN sensors without interfering with their daily activities. When designing a monitoring system, system performance reliability for competent healthcare is critical. Existing research has failed to create a large device capable of handling a large network or to improve WBAN topologies for fast transmitting and receiving patient data. As a result, in this research, we create a multisensor WBAN (MSWBAN) intelligent system for transmitting and receiving critical patient data. To gather information from all cluster nodes and send it to multisensor WBAN, a novel additive distance-threshold routing protocol (ADTRP) is proposed. In small networks where data are managed by the transmitting node and the best data route is determined, this protocol has less redundancy. An edge-cutting-based routing optimization (ES-EC-R ES-EC-RO) is used to find the best route. The Trouped blowfish MD5 (TB-MD5) algorithm is used to encrypt and decrypt data, and the encrypted data are stored in a cloud database for security. The performance metrics of our proposed model are compared to current techniques for the best results. End-to-end latency is 63 ms, packet delivery is 95%, security is 95.7%, and throughput is 9120 bps, according to the results. The purpose of this article is to encourage engineers and front-line workers to develop digital health systems for tracking and controlling virus outbreaks.

Fulltext Feasibility and Acceptability of the "About Me" Care Card as a Tool for Engaging Older Adults in Conversations About Cognitive Impairment

Grande SW, Epperly M, Tan KY, Yagnik S, Ellenbogen M, Pederson J, et al.

Ann Fam Med, 2025 Mar 24;23(2):117-126.
PMID: 40127970 DOI: 10.1370/afm.240165

PURPOSE: We aimed to address fears and lived experiences of cognitive decline among adults via whole-person conversations that elicit problems and goals that matter most to patients. Currently, 6.7 million Americans have Alzheimer disease or related dementias, with an additional 28 million people reporting subjective cognitive decline-a possible indicator of Alzheimer disease and related dementias. A review of tools for older adults with cognitive impairment showed strong clinical specificity, with insufficient whole-person support for patients. We developed and tested the feasibility and acceptability of a tool to enhance conversations for adults with cognitive impairment at the point of care.
METHODS: We conducted a feasibility study to build a conversation tool, guided by principles of shared decision making, called the "About Me" Care Card. Informed by an environmental scan, we created and pilot-tested prototypes at implementation sites. All phases were overseen by a multidisciplinary steering committee.
RESULTS: Fourteen diverse clinicians consisting of 7 clinician types across 7 institutions piloted the card during in-person visits or by telephone. Observations showed that the card (1) allowed time to elicit what matters most to patients, (2) created space for personalized care conversations, (3) opened an examination of social care needs, and (4) moderated emotional relationships between families and individuals.
CONCLUSION: A community-based codesign process led to a feasible tool for primary care teams to facilitate whole-person conversations with aging adults. The About Me Care Card appeared to broaden conversations compared with routine care. More work is needed to determine scalability and effects on outcomes.

The relative importance of peace of mind, grit, and classroom environment in predicting willingness to communicate among learners in multi-ethnic regions: a latent dominance analysis

Yin K, Zhou L

BMC Psychol, 2025 Apr 18;13(1):401.
PMID: 40251638 DOI: 10.1186/s40359-025-02676-2

From a holistic perspective of positive psychology, there is a dearth of knowledge regarding how its three underlying factors (i.e., positive subjective experience, positive individual traits, and positive collective institutions) co-shape learners' willingness to communicate (WTC), a critical facilitator of foreign language learning achievement. This research gap is particularly evident for learners in multi-ethnic regions who have been underrepresented in foreign language education in China. This issue may constrain our understanding of the contributions of positive psychology to the field of applied linguistics, since the role of positive psychological factors in influencing WTC may be distinct across diverse ethnic populations. Besides, the relative importance of these three factors in predicting WTC has yet to be investigated in latent models. Given that different pedagogical approaches may engender disparate perceptions and attitudes among learners, it is of the utmost importance to ascertain which factor should be prioritized in classroom psychological interventions, as well as in teacher training programs. To address these gaps, this study addressed the joint effect of positive subjective experience (foreign language peace of mind, FLPOM), positive individual trait (language-specific grit), and positive collective institution (classroom environment) on WTC using structural modeling analysis. Furthermore, the study employed latent dominance analysis to ascertain the relative importance of these three factors in promoting WTC. The sample consisted of 643 multi-ethnic foreign language students from five provinces in Western China. The findings suggested that FLPOM, grit, and classroom environment collectively stimulate learners' WTC. Notably, FLPOM, a factor that has not previously been examined in relation to in-class or face-to-face WTC, emerged as the most statistically significant predictor of WTC. Therefore, it is imperative that foreign language practitioners and learners recognize the significance of FLPOM in language learning and teaching in Chinese multi-ethnic regions.

Fulltext Measuring expected participation in project knowledge: analysing communication patterns in social messaging application using GUSC Model

Shahrinaz Ismail, Nordiana Jamaludin

Journal of Advanced Research Design, 2018;47(1):1-16.
MyJurnal

The advancement of technology has allowed a variety of tools for employees and
managers, or knowledge workers, to choose as communication tools, especially for
managing project teams. Instead of communicating and updating project progress
through emails and short messaging system, social messaging (SM) applications, such
as WhatsAppTM, are the current daily choice among them. The over-utilisation of the
SM applications has given an opportunity for a research on project knowledge
retention within project team, since it becomes an addiction to create new groups each
time a new project team is formed. It is believed that project knowledge resides within
these virtual groups, and this paper looks into how project knowledge is managed by
analysing the communication patterns against a measurement metrics based on
personal knowledge management (PKM) theory called GUSC Model. The
communication patterns found existed in the SM application are qualitatively
identified and mapped against the PKM processes within, with weighted score
assigned to each process to quantitatively measure the overall project knowledge
management participation. The differences among the organisational communication
levels, namely upper and lower level communication levels, are analysed and the final
result of participation expectation on member of SM application groups is presented.
The outcome of this research recommends the future intervention on SM application
usage and the application of knowledge management concept in current
communication tool.

Fulltext Circularly Polarized Broadband Printed Antenna for Wireless Applications

Samsuzzaman M, Islam MT

Sensors (Basel), 2018 Dec 04;18(12).
PMID: 30518080 DOI: 10.3390/s18124261

A simple, compact sickle-shaped printed antenna with a slotted ground plane is designed and developed for broadband circularly polarized (CP) radiation. The sickle-shaped radiator with a tapered feed line and circular slotted square ground plane are utilized to realize the wideband CP radiation feature. With optimized dimensions of 0.29λ × 0.29λ × 0.012λ at 2.22 GHz frequency for the realized antenna parameters, the measured results display that the antenna has a 10 dB impedance bandwidth of 7.70 GHz (126.85%; 2.22⁻9.92 GHz) and a 3 dB axial ratio (AR) bandwidth of 2.64 GHz (73.33%; 2.28⁻4.92 GHz). The measurement agrees well with simulation, which proves an excellent circularly polarized property. For verification, the mechanism of band improvement and circular polarization are presented, and the parametric study is carried out. Since, the proposed antenna is a simple design structure with broad impedance and AR bandwidth, which is a desirable feature as a candidate for various wireless communication systems. Because of the easy printed structure and scaling the dimension with broadband CP characteristics, the realized antenna does incorporate in a number of CP wireless communication applications.

Fulltext Design and Testing of an Experimental IPv4-to-IPv6 Transition Network

Mustaffa Samad

Scientific Research Journal, 2006;3(1):27-36.
MyJurnal

The Internet has been an integral part of the Information and Communication
Technology (ICT) community in recent years. New internet users have been
growing steadily over the years. This has lead to the depletion of new Internet
Protocol (IP) addresses worldwide. To overcome this predicament, the new
Internet Protocol version 6 (IPv6) had been introduced. The existing Internet
Protocol version 4 (IPv4) is expected to be eventually replaced by this IPv6.
The changeover from IPv4 to IPv6 is expected to be implemented progressively.
During this transition period, these two protocols are expected to coexist for
a number of years. IPv4-to-IPv6 transition tools have been designed to facilitate
a smooth transition from IPv4 to IPv6. The two most basic IPv4-to-IPv6
transition tools available are the hybrid stack mechanism and tunneling.
Tunneling is the encapsulation of IPv6 traffic within IPv4 packets so they can
be sent over an IPv4 infrastructure. This project was initiated to set up an
experimental IPv6 testbed, in order to study the performance as well as
transition and migration issues of IPv6 networks under controlled conditions.
This paper looks at how tunneling can be performed over existing internetwork
infrastructure at Fakulti Kejuruteraan Elektrik (FKE), UiTM.

Journal of Cognitive Sciences & Human Development, 2018;4(1):15-27.
MyJurnal

Work-related accidents is a controversial topic in Malaysia as evidenced by the increased number of occupational accidents throughout the years. The purpose of this research is to examine the relationship between management practices and safety performance in an or-ganization. The four management practices investigated are (a) training, (b) management commitment, (c) communication and feedback, and (d) employee involvement. The most effective safety practice is also identified. The data was collected at a manufacturing com-pany located in Shah Alam, Malaysia using closed-ended questionnaire. 95 respondents from the production line were involved in this study. The result found that training had a very weak relationship to the safety performance while the management commitment, as well as the communication and feedback, revealed to have a weak impact on safety perfor-mance. On the other hand, the analysis showed that employee involvement is the most ef-fective safety practice to the safety performance, as it had a moderate impact on safety per-formance.
