Objectives: There are increasing demands for personal assistance services which help the disabled to carry out their daily life. To use augmentative and alternative communication (AAC) approaches more effectively in daily communication, it is essential to include the appropriate core and fringe vocabulary in the AAC system. Considering the fact that there are few studies in Korea which have reported fringe vocabulary compared to core vocabulary, this study is aimed to develop a noun list that can be used to promote interactive communication between the disabled and their assistants in each communication situation.Methods: A literature review was conducted to elicit frequently used nouns in each communication situation. Then, a survey was carried out to identify nouns with high word commonality across 105 personal assistants.Results: Sixty-three nouns with more than 50% of word commonality across personal assistants were identified from the 244 fringe vocabulary; consisting of 112 nouns in the area of going out, 29 in cleaning, 27 in personal hygiene, 26 in cooking, 20 in meal supporting, 20 in other service areas, and 10 in commuting.Conclusion: The identified nouns are expected to help people with complex communication needs to express their needs and wants more clearly and effectively using those nouns embedded in their AAC systems. The list of nouns can be used not only for people who receive personal assistance services, but also for people who rely on AAC systems to express their daily needs.

Mobile health (m-Health) scenarios and Internet of Things (IoT) technologies form an important direction for enhancing medical systems for Ambient Assisted Living (AAL). Yet current development meets with two challenges: 1) use of patient's health data with strong security guarantees in mobile network and resource-constrained assumptions and in emergency situations, 2) inclusion of personal data to the entire system for “smart” service construction and delivery. This paper presents a smart space based architectural model that adopts emerging IoT technologies to enable security of personal mobile data and their intelligent utilization in health services. To support the service intelligence, the authors employ the smart spaces approach with its prominent technologies adopted from IoT and Semantic Web. The intelligence and security solutions are considered symbiotic to present better user-experience, security level, and utility of a system.

Testo completoAbstract (sommario):
The Covid 19 challenge, the increased aging population, and the modern way of living are increasing the need for health monitoring communications services. Healthcare monitoring is a very important research field of study. This is related in finding new, more efficient ways in health data communications with three main quality of service requirements: low delay, high security, high quality data transmission. Considering these requirements and recent developments in domestical health monitoring services, it is important not only the equipment used for health monitoring sensing but also the communication protocol used to access the data center. In this paper we develop a new communication protocol for ad-hoc wireless network created by the sensors used for personal health monitoring systems installed in patient wrists. This is a hierarchical protocol where the sensors communicate through a virtual infrastructure that helps to collect the data from the personal health monitoring equipments in an efficient way even in the areas with no wireless infrastructure. The communication scheme ensures a hierarchy of nodes that gets translated to hierarchy of costs as only a few nodes need to have a larger processing power resulting in a lower battery consumption for most of the patients. The neighbourhood area is divided into virtual cells where each cell is represented from one node center that holds the communication for all the surrounded nodes and forwards its information towards the next cell center found in the direction of the sink. As a result the information collected even in the fields without any wireless infrastructure might be carried towards the cells that are in a communication distance with the sink. The updated information data is forwarded toward the data centers to be analysed by the specialists. Taking in consideration that even in the urban areas the elderly population doesn’t have internet services, this ad-hoc communication protocol represents a good solution for health monitoring equipments. Moreover, the same communication protocol can be used for signaling life signs in war areas.

Testo completoAbstract (sommario):
A personal mobility service (PMS) is developed to support personalized travel options for users in autonomous transportation systems (ATS), based on a macro-system state and micro-user behavior. However, this functionality necessitates processing and transmitting vast amounts of data, raising concerns about user privacy protection during data processing and transmission within the PMS. Furthermore, the PMS must be maintained and perform well, while preserving privacy. Therefore, we propose a novel federated PMS, denoted as a FPMS. Specifically, the FPMS can serve users’ personal mobility needs by facilitating the collaboration between the physical and information domains. Then, a common framework for FPMS architectures, which captures the features of ATSs, is proposed and discussed from both physical and logical perspectives, which include both the logical architecture and physical architecture; and we present the key algorithms for the FPMS, in conjunction with a artificial neural network (ANN). Additionally, in static estimation scenarios, the FPMS demonstrated a similar accuracy for three different models compared to the traditional PMS, while reducing the computing time by approximately 60% and communication resource consumption by approximately 85%.

A global phenomenon of population ageing and an increasing number of patients with chronic diseases place substantial additional pressure on healthcare systems. A possible solution for this problem is a new emerging sort of pervasive personal healthcare service that is focused on the patient and allows the patient to be actively involved in his or her own health care. In this paper, we propose the architecture of the pervasive personal healthcare service which is based on the existing technologies available to almost everyone. Along with the conventional request-response synchronous communication, the proposed system features asynchronous communication based on publish-subscribe-notify model. In order to perform asynchronous communication, a web application server is integrated with the Google Cloud Messaging service. The communication between mobile device and servers is carried out through the available Wi-Fi or mobile networks, whereas Bluetooth protocol is conventional for Body Sensor Networks consisting of wearable sensor devices. We also present a mobile application which has been developed with use-case driven approach for both patients and medical personnel. The introduced application has a form of a nonintrusive customized mobile social network. We explain usage scenarios that clarify the required functions and present conclusions based on the system test.

Testo completoAbstract (sommario):
Many financial institutions interact with their customers via short message services (SMS), which is today one of the fastest and most powerful means of communicating information around the world. This information can sometimes be an access code such as the unique password (OTP) for two-factor authentication (2FA) or banking information and personal identities. All this data is confidential, and it is a major disadvantage to send them since an SMS service does not provide data encryption during network transmission and on mobile. Recently, OTPs via SMS have suffered from strong attacks that intercept messages. In order to avoid attacks and offer effective content security to 2FA credentials sent via SMS, the authors propose an SMS encryption mechanism using a post quantic cryptosystem quasi-cyclic MDPC and an electronic signature of the OTPs. Finally, this article performs an implementation and a security analysis of the proposal.

Testo completoAbstract (sommario):
We discuss how a short-range wireless communication service implemented for modern mobile communication devices can provide additional value for both the consumer and the service/product provider. When used as an information search tool, such systems allow services and products being promoted at the location they are available. For the customer, it may provide a “digitally augmented vision”, an enhanced view to the current environment. With data filtering and search rules, this may provide a self-manageable context, where the user's own personal environment and preferences to the features available in the current surroundings cooperate with a direct connection to the web-based social media. A preliminary design for such service is provided. The conclusion is that the method can generate additional revenue to the company and please the customers' buying process. In addition to the marketing, the principles described here are also applicable to other forms of human interaction.

Purpose In the Web 2.0 era, users massively communicate through social networking services (SNS), often under false expectations that their communications and personal data are private. This paper aims to analyze privacy requirements of personal communications over a public medium. Design/methodology/approach This paper systematically analyzes SNS services as communication models and considers privacy as an attribute of users’ communication. A privacy threat analysis for each communication model is performed, based on misuse scenarios, to elicit privacy requirements per communication type. Findings This paper identifies all communication attributes and privacy threats and provides a comprehensive list of privacy requirements concerning all stakeholders: platform providers, users and third parties. Originality/value Elicitation of privacy requirements focuses on the protection of both the communication’s message and metadata and takes into account the public–private character of the medium (SNS platform). The paper proposes a model of SNS functionality as communication patterns, along with a method to analyze privacy threats. Moreover, a comprehensive set of privacy requirements for SNS designers, third parties and users involved in SNS is identified, including voluntary sharing of personal data, the role of the SNS platforms and the various types of communications instantiating in SNS.

The paper deals with comparative research of the communication security of e-Government services in Germany and Hungary. The focus point of the research is to analyse the cryptographic security algorithms and protocols which encrypt communication in the relations of the citizen and a governmental body. The analysis includes the general e-Government portals, central web services, and specialised services, like taxation and criminal record extracts. The actuality of the topic lies in the fact that the security of the citizens’ personal data, used, stored and transferred by the governmental bodies can be in danger. Two examples are the loss of 25 million UK citizens’ personal data in 2007 because of a failure of the UK Customs Service and the compromise personally identifiable information of 191 million US citizens, stored in the Voter Database in 2015. The goal of the research is to check the current practice used for governmental communication, based on international standards and current practices. The study compares the e-administration systems of a country of Central Europe which is considered less developed in e-government systems and processes than a Western European country. Based on the evaluation, which can be found at the end of this study, those persons who are responsible for the operation of such systems, can see the actual benchmarks of the communication security. So, this way they can learn about the usage of what communication protocols and cryptographic algorithms are recommended and under what settings.

ABSTRACT Introduction The current model for treating behavioral health patients requires that providers and patients be in the same location for appointments. However, deploying warfighters present a challenge to this current model. Recent advances in technology make telehealth or virtual visits a viable option to replace the current model. This project leveraged mobile technology to see if performing tele-behavioral health visits presented a viable option to the current in-person model for future deployed warfighters. At the time of this publication, the authors note the current pandemic lends all the more urgency to the need for enhancing our video communication platforms for remote monitoring with the Military Health System. Materials and Methods The research team assessed existing Internet protocol-based desktop teleconferencing solutions, generically known as a Web Real-Time Communications (WebRTC) system, for establishing a secure connection to a Service Members personal mobile device outside of the Department of Defense (DoD) network. Of the five existing WebRTC systems evaluated, only the backbone component to the existing Defense Information Systems Agency Global Video Services (DISA GVS) known as Vidyo, was suitable to meet DoD security requirements and still connect with both major operating systems (OS) on mobile devices. An existing DoD program of record mobile application, mCare, was integrated with Vidyo desktop technologies to form what the research team called “Mobile Connect.” Results Deployment of the Mobile Connect product yielded distinct differences and high levels or variability between the .osd.mil and the army.mil network connections over time. These network differences impacted quality of service solution where Mobile Connect could not be used to provide care between the .mil and patient’s personal mobile devices from a osd.mil domain connection. The current DoD WebRTC systems offer potential solutions but presently cannot connect with personal mobile devices in their current configurations. Additionally, any WebRTC system used by the DoD for future connections to personal mobile device must leverage commercial Single Socket Layer certificates (e.g., not DoD issued), or the communications with the mobile device will fail as a result of an authentication error. Conclusion It is technically feasible to provide desktop Video Tele-Conference capabilities from a .mil computer to a personal mobile device without compromising DoD security and information assurance requirements using future WebRTC systems. Approved ports, protocols, and system settings must be configured to accept both inbound and outbound, encrypted traffic to/from personal mobile devices to maintain consistent quality of service with all DoD networks. Of the current DoD WebRTC options, working with the DISA GVS Program Manager to expand services to support commercial mobile devices has the highest probability of future success.

Testo completoAbstract (sommario):
Improved health care services can benefit from a more seamless exchange of medical information between patients and health care providers. This exchange is especially important considering the increasing trends in mobility, comorbidity and outbreaks. However, current Electronic Health Records (EHR) tend to be institution-centric, often leaving the medical information of the patient fragmented and more importantly inaccessible to the patient for sharing with other health providers in a timely manner. Nearly a decade ago, several client–server models for personal health records (PHR) were proposed. The aim of these previous PHRs was to address data fragmentation issues. However, these models were not widely adopted by patients. This paper discusses the need for a new PHR model that can enhance the patient experience by making medical services more accessible. The aims of the proposed model are to (1) help patients maintain a complete lifelong health record, (2) facilitate timely communication and data sharing with health care providers from multiple institutions and (3) promote integration with advanced third-party services (e.g., risk prediction for chronic diseases) that require access to the patient’s health data. The proposed model is based on a Peer-to-Peer (P2P) network as opposed to the client–server architecture of the previous PHR models. This architecture consists of a central index server that manages the network and acts as a mediator, a peer client for patients and providers that allows them to manage health records and connect to the network, and a service client that enables third-party providers to offer services to the patients. This distributed architecture is essential since it promotes ownership of the health record by the patient instead of the health care institution. Moreover, it allows the patient to subscribe to an extended range of personalized e-health services.

In order to solve the library’s demand for computer network technology, a research on the library’s personal system service is proposed. A library-based self-service model was originally designed and developed. The system is developed from six aspects: resource association analysis and mining, reading interest analysis, data collection, personal service, personal service scheduling, and data warehouse. Secondly, it shows that this study has done some research on library application itself and completed some research. Finally, libraries can accomplish personal services in a variety of ways, such as distributing modifications, smart administrators, vertical portals, pushers, and more. In foreign libraries and universities represented by North Carolina State University and the Data and Information Center of the Chinese Academy of Sciences, the construction of personal data in digital libraries has become an important part of future development. According to the law, 57.9% and 65.0% of users ranked search engines as second only to e-mail in the China Internet Improvement Data released by the China Internet Network Information Center in 2000 and 2005, respectively.

In summer 2015, we conducted an exploratory study of how people in the U.S. use and respond to robot-like systems in order to achieve their needs through mediated customer service interfaces. To understand this process, we carried out three focus groups sessions along with 50 in-depth interviews. Strikingly we found that people perceive (correctly or not) that interactive voice response customer service technology is set up to deter them from pursuing further contact. And yet, for the most part, people were unwilling to simply give up on the goals that motivated their initial contact. Consequently, they had to innovate ways to communicate with the automated systems that essentially serve as gatekeepers to their desired ends. These results have implications for communication theory and system design, especially since these systems will be increasingly presented to consumers as social media affordances evolve.

African American (AA) men remain one of the most disconnected groups from health care. This study examines the association between AA men’s rating of health care and rating of their personal physician. The sample included 12,074 AA men aged 18 years or older from the 2003 to 2006 waves of the Consumer Assessment of Healthcare Providers and Systems Adult Commercial Health Plan Survey. Multilevel models were used to obtain adjusted means rating of health care systems and personal physician, and the relationship of ratings with the rating of personal physician. The adjusted means were 80 (on a 100-point scale) for most health ratings and composite health care scores: personal physician (83.9), specialist (83.66), health care (82.34), getting needed care (89.57), physician communication (83.17), medical staff courtesy (86.58), and customer service helpfulness (88.37). Physician communication was the strongest predictor for physician rating. AA men’s health is understudied, and additional research is warranted to improve how they interface with the health care system.

Purpose The purpose of this paper is to explore the role of interpersonal relationships (IPRs) in service supply chain integration (SSCI) in terms of strategic alliance, information integration, and process integration. Design/methodology/approach The research employs an exploratory/investigational approach to multiple case studies and empirically investigates effects of IPRs in SSCI. The data were mainly collected through semi-structured interviews with senior management staff from four service companies and their suppliers or customers in New Zealand. Archival data from the Internet and company documentations were also applied. Findings The authors find that three dimensions of IPRs influence SSCI in different ways. The effect of IPRs on SSCI is indirect: personal affection acts as an initiator, and personal credibility works as a “gate-keeper” and strengthens the confidence of interactive partners, while personal communication, a facilitator, plays a more important role in SSCI than personal affection and credibility. Practical implications The research provides managers in service supply chains the awareness of the importance of IPRs, as well as the characteristics of IPRs, in order to best utilize available resources. Managers should synergize all three dimensions of IPRs’ resources: make efforts to cultivate personal affection to avoid the instinctive isolation modern technology brings; attempt to accumulate positive personal credibility profiles; focus more on the role of personal communication and retain physical contact in SSCI processes. Originality/value This study contributes to SSCI literature by extending from the inter-organizational relationships (IORs) to interpersonal level relationships to explore the inner influence mechanism. Also, it explores the role of IPRs on all three dimensions of SSCI simultaneously rather than individual dimensions independently. Finally, it contributes to resource orchestration theory (ROT) by synthesizing three dimensions of IPRs resources, and IORs resources in order to achieve capabilities of SSCI. The study develops the individual-level research in supply chain integration (SCI) to a further depth.

It is clear that to meet the new demands of wireless customers, conventional cellular service providers and upcoming Personal Communication Service (PCS) providers for conventional phone service and high bandwidth wireless LAN must upgrade their networks to provide complete radio coverage. This evolution has motivated the need for low-cost systems that transport radio signals to and from areas of poor signal coverage. The most important area where this problem must be solved is inside of buildings, since this is where people spend most of their time. Unfortunately, the in-building enviroment is also the ost challenging area to provide radio coverage due to severe attenuation and multi-path effects. The problem must be tackled from the viewpoint of optimization of performance/cost ratio of the network. In this paper, we describe a system-level approach to tackle this problem. We demonstrate how one can trade-off hardware performance, which represent cost, with proper choice of system architecture which includes, among other factors, in-buiding radio environment, to arrive at an optimum network solution technically and economically.

Testo completoAbstract (sommario):
The management of reproductive health service for youth has become an important issue during the recent year. However, management has no clear idea about the influential factors of concern to. In this paper, we will discuss these influence factors that affect the management of youth reproductive healthcare service. Mixed methods were used for data collection, including qualitative methods that were conducted by in-dept interview and analyzed by binary logistic regression. According to the analysis, we found six factors that affect the management of reproductive health service, including (1) personal expense, (2) communication within the family, (3) fear of parents reactions, (4) the bureaucratic process of healthcare services, (5) the limitation of healthcare services, and (6) healthcare providers. Then, we reduced the six factors into three group factors that we call three systems to explain these important factors that are of concern to management of reproductive health service. These include the personnel system, service system, and the family support system.

Objective. Identification and systematization of activators of marketing communications, as an iterative integrator of processes, factors, tools that ensure the promotion of tourist services. Methods. In the research process, the following methods were used: theoretical generalization (when characterizing the concepts of "marketing communications", "tourist service"), analysis and synthesis (for the formation of a complex of methods of marketing communications of tourist enterprises), matrix (when systematizing the activators of marketing communications regarding the sale of tourist services). Results. Tourist services, i.e. transportation, temporary accommodation, food, excursion, resort, sports, entertainment and other services are provided by tour operators, travel agents, accommodation establishments, restaurant establishments, transport organizations, etc. That is, the range of business entities that must ensure interaction and communication is wide and requires established communications. The communication policy of the business entity involves the integration of management decisions regarding the goals of marketing communications, the implementation of the communication process for their implementation, a set of marketing communications methods that should ensure an effective commercial result from the sale of tourist services. In a certain sense, the provision of tourist services can be represented as a communication process, within the framework of which communications take place between travel agencies and tourists, as well as within these groups. As a result, different marketing communication systems can be considered: between travel agencies and customers, between travel agencies and between tourists, all of which require different methods of marketing communications. In order to successfully implement the communication process, which has an iterative feature, i.e. the possible unlimited sequence options and combinations of communication policy elements, it is necessary to identify and systematize the activators of marketing communications regarding the implementation of tourist services. By activators we will understand the factors, tools, processes of marketing communications that ensure the promotion of tourist services, overcoming the negative consequences of macroeconomic (consequences of the war in Ukraine, political, economic, social instability, etc.) and microeconomic (limitation of costs for marketing communications, lack of a strategic vision for the development of tourist enterprises, shortcomings in the training of personnel involved in the field of tourism, etc.) upheavals. The activators of marketing communications regarding the sale of tourist services can be considered separate processes related to the quality of tourist services, demand formation, informational support of tourist enterprises, social moments of communication with consumers and the public, etc.; factors (institutional, social, cultural, infrastructural); tools (formally established rules and informal traditions, market segmentation, modification of tourist services, language environment, entrepreneurial culture, special information systems) and methods of marketing communications (advertising, sales promotion, personal sales, PR, sponsorship, direct marketing, direct communications, promotion -tours), which in the proposed combination ensure the realization of the goals of marketing communications of tourist enterprises.

Testo completoAbstract (sommario):
In order to guarantee the privacy of users’ data, the Brazilian government created the Brazilian General Data Protection Law (LGPD). This article made a diagnostic of Brazilian organizations in relation to their suitability for LGPD, based on the perception of Information Technology (IT) practitioners who work in these organizations. We used a survey with 41 questions to diagnose different Brazilian organizations, both public and private. The diagnostic questionnaire was answered by 105 IT practitioners. The results show that 27% of organizations process personal data of public access based on good faith and LGPD principles. In addition, our findings also revealed that 16.3% of organizations have not established a procedure or methodology to verify that the LGPD principles are being respected during the development of services that will handle personal data from the product or service design phase to its execution and 20% of the organizations did not establish a communication process to the personal data holders, regarding the possible data breaches. The result of the diagnostic allows organizations and data users to have an overview of how the treatment of personal data of their customers is being treated and which points of attention are in relation to the principles of LGPD.

Testo completoAbstract (sommario):
People with severe mental illness suffer from a high burden of oral diseases, which can negatively impact their physical and mental well-being. Despite the high burden, they are less likely to engage in oral health care including accessing dental services. We aimed to identify both the service users’ and service providers’ perspective on the barriers and facilitators for maintaining oral health and dental service use in people with severe mental illness. Qualitative exploration was undertaken using dyadic or one-to-one in-depth interviews with service users in the UK with a diagnosis of schizophrenia, schizoaffective disorder or bipolar disorder. Service providers, including mental health and dental health professionals, and informal carers (people identified as family or friend who are not paid carers) were also interviewed. Thematic analysis of the data revealed three main cross-cutting themes at the personal, inter-personal and systems level: amelioration of the problem, using a tailored approach and provision of comprehensive support. The main barriers identified were impact of mental ill-health, lack of patient involvement and tailored approach, and accessibility and availability of dental services including lack of integration of services. The main facilitators identified were service providers’ effective communication skills and further support through the involvement of carers. The findings suggest that the integration of dental and mental health services to provide tailored support for overall health and well-being, including the oral health of the patient, can better support people with severe mental illness regarding their oral health needs.

Testo completoAbstract (sommario):
Typically, users' service requests, which are similar with varying preferences on non-functional attributes, may result in ranked lists of services that partially meet their needs due to conflicting non-functional attributes. The resultant multiple ranked lists of services that partially satisfies the user's request makes it challenging for the user to choose an optimal service, based on his/her preference. This work proposes a method that aggregates multiple ranked lists of services into a single aggregated ranked list, where top ranked services are selected for the user. Two algorithms are proposed; 1) Rank Aggregation for Complete Lists (RACoL), that aggregates complete ranked lists and 2) Rank Aggregation for Incomplete Lists (RAIL) to aggregate incomplete ranked lists. Examples using real-world airline services to evaluate both algorithms show that the results from both proposed algorithms closely represent the sets of ranked lists better than using alternative approaches. Experiments were also carried out to validate their performance.

Testo completoAbstract (sommario):
There are multiple methods of communication for the transmission of every type of alarm. In the case of emergency systems, they are usually controlled by private companies that work as bridges between the source and the receiver of an emergency. Furthermore, it is necessary to use an independent communication system for each building, requiring human vigilance, leading to an increase in infrastructure and service costs as well as response time. This paper proposes a hybrid network by combining both wireless personal access network (WPAN) and low power wide access network (LPWAN) communication for the complete development of a communication architecture oriented to an emergency system. The main aim of this work is to provide a global emergency system that is focused on fire detection but is also suitable for other critical events, with low energy consumption, a wide communication range covering up to 50 km, and a low cost of service and infrastructure. This proposal reduces the total energy consumption of the system with respect to typical fire detection systems.

Testo completoAbstract (sommario):
In service selection, an end user often has his or her personal preferences imposing on a candidate service’s non-functional properties. For a service selection process promoted by a group of users, candidate services are often evaluated by a group of end users who may have different preferences or priorities. In this situation, it is often a challenging effort to make a tradeoff among various preferences or priorities of the users. In view of this challenge, a multi-criteria decision-making method, named AHP (Analytic Hierarchy Process), is introduced to transform both qualitative personal preferences and users’ priorities into numeric weights. Furthermore, a QoS-aware service evaluation method is presented for a shared service’s co-selection taking advantage of AHP theory. At last, a case study is presented to demonstrate the feasibility of the method.

Testo completoAbstract (sommario):
Internationally, community healthcare is provided by personal health budgets or personalised schemes as part of a consumer-directed care emphasis. Although the introduction of a personalised scheme in Australia has improved the lives of many, people with psychosocial disability (PSD) and their families have experienced many challenges with service integration. Six focus groups with 17 National Disability Insurance Scheme (NDIS) support workers were conducted between June and November 2022. Participants were asked semistructured questions about their engagement with emergency department (ED) clinicians when presenting with a person with PSD and NDIS plan. They were also asked how they contribute to service integration to improve communication practices between the two services. A qualitative, descriptive thematic analysis approach was used. Results indicate there is a need for improved service integration pathways between the ED and NDIS services. The thematic analyses identified five main themes: the ED is harmful and not safe, but nowhere else to go; make the ED safe; further training for ED staff; improving communication across services; and alternatives to the ED. This study reports NDIS support worker’s experience when supporting a person they are caring for in the ED. NDIS support workers have an understanding of the needs of the people they care for;their wisdom can contribute greatly to ED clinical responses in crisis care. Recommendations are offered to assist with service integration between the two systems.

Testo completoAbstract (sommario):
The banking system of the Russian Federation is based on Federal legislation, as well as industry and inter-industry standards developed by the International community and the Central Bank of the Russian Federation. The introduction and development of remote banking services is the most popular direction in the modern banking system. The term ‘remote banking service’ refers to the technology of providing services for the remote transmission of orders by credit institutions (without clients’ presence in bank office), using different communication channels. Information security in bank-client systems is carried out by several types of protection. Client authentication is confirmed by the use of an electronic signature. The data channel and the data itself are encrypted. In order to implement the above-described functions of the bank-client system in any software, the client must first generate and register cryptographic keys with the bank and obtain electronic digital certificates. In addition to the protection of the transferred data, personal data that have entered the system of remote banking services also need protection. The research purpose is to analyze the system of remote banking services, to identify regulatory and methodological documents regulating information security issues, options for meeting the requirements of regulators. Confirmation or refutation of the issue’s urgency should be considered as research results.

Testo completoAbstract (sommario):
The capabilities of the people, processes, and technology are important factors to consider when exploring continuous use to create value. Multiple perceptions and attitudes towards self-service systems lead to various usage levels and outcomes. With complex analytical structures, organizations need a better understanding of IS value and users’ satisfaction. Incompatibility reduces the purpose of self-service analytics, decreasing its value and making it obsolete. In a qualitative, single case study, 20 interviews in a major digital Scandinavian marketplace were explored using the expectation–confirmation theory of continuous use to explore the mechanisms influencing the sustainability of self-service value. Two main mechanisms were identified: the personal capability reinforcement mechanism and the environment value reinforcement mechanism. This study contributes to the post-implementation and continuous use literature and self-service analytics literature and provides some practice implications to the related industry.

Testo completoAbstract (sommario):
We consider the problem of minimizing paging cost, subject to delay constraint, in Personal Communication Services Network (PSCN) and present two intelligent paging strategies for third generation systems. They are termed as sequential intelligent paging (SIP) and parallel-o-sequential intelligent paging (PSIP). Unlike the conventional blanket paging where all cells in a location area are polled at a time, in SIP (PSIP) one cell (a group of cells) is polled at a time. The proposed schemes lead to a decrease in paging signaling load at the cost of some extra processing power. When better discovery rate per cycle is expected irrespective of the incoming traffic PSIP is always preferred to other paging schemes primarily because of its less amount of polling delay. If the incoming traffic rate is low, SIP performs better than PSIP in terms of paging cost per cycle. However, the polling costs per cycle and the discovery rates for both the schemes become equal as number of paging requests per cycle increases. An improvement in respect of paging cost per cycle and discovery rate over conventional paging is shown with the help of simulation results.

The COVID-19 pandemic has caused a decline in various aspects of the economy, including the fashion sector. Many fashion retailers have closed, so sales have fallen. However, many retailers can also adapt and change using new communication channels. This change presents new challenges for fashion companies and retailers to integrate channels into omnichannel services. This study aims to analyze the factors influencing customer behavior in omnichannel services through their intention to accept and use new technology in shopping. This study adopts the UTAUT2 model by adding two new variables: personal innovation and perceived security. This model was tested on 353 samples from Uniqlo customers residing in Indonesia. This research method uses a Quantitative PLS-SEM approach. This study tested the outer model, inner model, and hypothesis t-test with a bootstrap procedure using SmartPLS software. The results showed that the performance expectation factor did not affect the omnichannel purchase intention variable because the t-statistic value is less than 1.65. Meanwhile, other factors such as effort expectation, social influences, habits, hedonic motivation, perceived security, and personal innovativeness affect omnichannel purchase intentions because the t-statistic value is more than 1.65. The most positive and significant factor is personal innovativeness. Based on the results of this study, it is revealed that digitalization creates challenges for companies in maintaining digital businesses. Through various omnichannel service channels, this research can identify the factors influencing consumers' purchase intention

Testo completoAbstract (sommario):
The construction of mass service systems, namely automated control systems, requires preliminary analysis and modeling of traffic in their communication networks. Mathematical models of various types of traffic have been developed for public networks, which allows to estimate the necessary functional characteristics of equipment for building a communication network, depending on the number of users. Low-bandwidth communication networks, which are built on the basis of ultra high frequency and very high frequency (UHF/VHF) radio stations, are distinguished by low speed, high delay and jitter of data transmission. To work in such communication networks, special data transmission protocols are adapted and developed. In this paper, a study of the characteristics of audio and video traffic in low-bandwidth communication networks is carried out, which are built on the basis of UHF/VHF radio stations, which will allow creating a software implementation of simulated traffic modeling for the further determination of the services availability at the stage of planning and designing the communication system. Two personal computers and two modern RF‑7850M-HH UHF/VHF radio stations were used to study the characteristics of audio traffic. The radio stations worked in three operating modes: narrowband mode with a fixed carrier frequency FF, narrowband mode with pseudo-random adjustment of the operating frequency QL1A, and wideband mode ANW2C. The voice was transmitted in digital mode using the built-in MELP 2400 codec, and the "iperf-v2.0.5" software was used to determine the characteristics of the audio traffic on personal computers connected to these radio stations. Two personal computers, two modern RF‑7850M‑HH UHF/VHF radio stations, a video encoder and a video camera were used to study video traffic characteristics. The radio stations operated in ANW2C broadband mode. To evaluate the characteristics of the video traffic, the Wireshark software was used on a personal computer, with the help of which the video broadcast from the video encoder was presented. It was found that voice transmission in low-speed communication networks based on UHF/VHF radio stations occupies a bandwidth of 2 Kbit/s - 2.5 Kbit/s, and when voice and data are simultaneously transmitted in radio stations, data buffering and jitter increase. The resolution, bitrate, FPS, and necessary bandwidth of video traffic that can be transmitted via UHF/VHF radio communication channels are determined. Based on the conducted research, recommendations are provided for the transmission of video traffic through low-bandwidth communication channels.

Testo completoAbstract (sommario):
A broad spectrum systems theory approach to the delivery of psychological services is presented. The target population includes the athletes, coaches, administrators, ski company representatives, and family members. The delivery of service involves individual dyadic and group sessions. The methods of service include educational, clinical, organizational, and a research data base. The major goal is to instill individual self-monitoring and self-control of personal well-being and achievement. Utilizing several theoretical frameworks such as behavioral, cognitive, humanistic, group dynamics, and insight oriented has worked best. Success of the program is multifactored: (a) being willing to commit a major amount of time to a single sport; (b) providing a broad range of services, from mental skills training, crises intervention, injury prevention and rehabilitation to team building, communication, and referral of individual to practitioners; (c) attending to organizational issues and program evaluation; and (d) common sense, practicability, and a willingness to be flexible with programs.

Testo completoAbstract (sommario):
In order to incorporate different communication standards into a single device, a compact quad-band slot antenna is proposed in this paper. The proposed antenna is composed of a dielectric substrate, T-shaped microstrip patch with a circle slot and an inverted L-slot, and a comb-shaped ground on the back of the substrate. By adopting these structures, it can produce four different bands, while maintaining a small size and a simple structure. Furthermore, a prototype of the quad-band antenna is designed and fabricated. The simulated and measured results show that the proposed antenna can operate over the 1.79–2.63 GHz, 3.46–3.97 GHz, 4.92–5.85 GHz, and 7.87–8.40 GHz, which can cover entire PCS (Personal Communications Service, 1.85–1.99 GHz), UMTS (Universal Mobile Telecommunications System, 1.92–2.17 GHz), WCDMA (wideband code-division multiple access, 2.1 GHz), Bluetooth (2.4–2.48 GHz), WiBro (Wireless Broad band access service, 2.3–3.39 GHz), WLAN (Wireless Local Area Networks, 2.4/5.2/5.8 GHz), WiMAX (Worldwide Interoperability for Microwave Access, 2.5/3.5/5.5 GHz), and X-band SATcom applications (7.9~8.4 GHz). The proposed antenna is particularly attractive for mobile devices integrating multiple communication systems.

We have made great progress in resolving the crucial problem of location privacy in Vehicular Impromptus Networks (VANETs), an essential component of Intelligent Traffic Systems (ITS), using our innovative block chain-based trust management methodology. VANETs' high inherent mobility has long presented security issues, especially when it comes to using Location-Based Services (LBS). Our creative solution gives cars the ability to request LBS while protecting their personal data with a secure verification process. Vehicle privacy is protected via the creation of anonymous shrouding zones, and vehicle behaviour is controlled and governed by an advanced trust management algorithm. By using block chain technology, the system's data security is strengthened even more, resulting in a strong, impenetrable architecture. Thorough testing has proven the system's resilience against a range of assaults based on trust models, proving its efficacy in protecting vehicle privacy. The outcomes of our simulation demonstrate the practicality of our suggested method in actual VANET circumstances, pointing to the possibility of a new era in safe and private ITC systems.
