The influence of changes of typical organizational management structures in transport companies on the effectiveness of its adaptation to the changing environment is analyzed.
 The impact is studied which affects the efficiency indicators of increasing the intensity of communication flows, including the formation of the position of a communication broker in the organization structure, an increase in the number of communication channels per agent, an increase in the intensity of interaction between individual agents when using modern means of communication, such as corporate messengers, online meetings, videoconferences.
 The research method is numerical modeling of the behavior of a transport industry company, presented as a set of interacting agents. The nature of the organization model construction reflects the prevailing organizational culture in it (the study considers models of two types of organizational culture – hierarchy and adhocracy).
 The novelty of the work is in quantifying the effectiveness of the transport organization in processing information about changes in the environment through modifications of the organizational structure.
 The results of the study show that the organizational effectiveness is determined by the static and dynamic characteristics of the organizational management structure. Static characteristics include the depth of hierarchy levels, the density of interaction between agents and departments in the organization; dynamic characteristics include the speed of information dissemination, indicators of the impact of agents on each other.
 Conclusions. A comprehensive analysis of the environment, the organizational structure of management and the level of training individual agents that make up the organization allows to select a modification of the communication environment that ensures an increase in the effectiveness of the adaptive abilities of the transport industry organization.

A java servlet based transaction broker for internet of things edge device communications

Internet of things (IoT) technology is growing exponentially in almost every sphere of life. IoT offers several innovation capabilities and features, but they are also prone to security vulnerabilities and risks. These vulnerabilities must be studied to protect these technologies from being exploited by others. Cryptography techniques and approaches are commonly used to address and deal with security vulnerabilities. In general, the message queuing telemetry transport (MQTT) is an application layer protocol vulnerable to various known and unknown security issues. One possible solution is to introduce an encryption algorithm into the MQTT communication protocol for secure transmission. This study aims to solve the security problem of IoT traffic by using a secure and lightweight communication proxy. The strategy behind this communication broker acts as a network gateway providing secure transaction keys to all IoT nodes in the network. This task uses a java servlet and elliptic curve cryptography (ECC) algorithm to generate identity encryption keys in a component-based web transaction infrastructure. This approach encrypts the data before it is sent via the MQTT protocol to secure the communication channel and raise the security device and network transactions.

통합 SNS 게이트웨이를 위한 웹 서비스 어댑터 구현 및 성능 분석

본 논문은 모바일 SNS 트래픽을 줄이는 방안으로 통합 SNS 게이트웨이를 이용하는 방법을 제시한다. 통합 SNS 게이트웨이는 모바일 클라이언트와 SNS 서버 사이에서 통신 중계자 역할을 한다. 통합 SNS 게이트웨이 내에서 SNS 서버와의 통신을 담당하는 웹 서비스 어댑터의 역할을 제안하고 구현하였다. 또한, 통합 SNS 게이트웨이 내의 캐시 엔진을 사용하여 사용자가 통합 SNS 게이트웨이를 통하여 특정 SNS 서버에게 콘텐츠를 요청할 때 발생하는 트래픽량과 응답 시간에 대한 성능을 측정하고 분석하여 결과를 제시한다. In this paper, we present integrated SNS Gateway as way to reduce mobile SNS traffic. Integrated SNS gateway's role is communication broker that located between mobile clients and SNS server. In Integrated SNS gateway, web service adapter communicates with SNS Server. Experiment was performed in aspects of contents RTT and network traffic. We evaluate and propose performances of integrated SNS gateway using gateway.

A user-centric network communication broker for multimedia collaborative computing

The development of collaborative multimedia applications today follows a vertical development approach, where each application is built on top of low-level network abstractions such as the socket interface. This stovepipe development process is a major inhibitor that drives up the cost of development and slows down the innovation pace of new generations of communication applications. In this paper, we propose a network communication broker (NCB) that provides a unified higher-level abstraction for the class of multimedia collaborative applications. We demonstrate how NCB encapsulates the complexity of network-level communication control and media delivery, and expedites the development of applications with various communication logics. We investigate the minimum necessary requirements for the NCB abstraction. We identify that the concept of user-level sessions involving multiple parties and multiple media, is critical to designing a reusable NCB to facilitate next-generation multimedia communications. Furthermore, the internal design of NCB decouples the user-level sessions from network-level sessions, so that the NCB framework can accommodate heterogeneous networks, and applications can be easily ported to new network environments. In addition, we demonstrate how the extensible and self-managing design of NCB supports dynamic adaptation in response to changes in network conditions and user requirements.

Tri-generational family conversations: communication accommodation and brokering.

Communication between grandparents and grandchildren can be superficial because of insufficient common ground between them. Among Chinese immigrant families in New Zealand, communication is complicated by linguistic mismatches, as grandparents may be proficient only in Chinese and grandchildren in English. To surmount these communication barriers, middle-aged parents (who know the cultures and languages of both grandparents and grandchildren) may play the role of a 'communication broker' to encourage and assist the two generations to conversationally move towards each other. We identified 35 cases (tokens) of brokering in 12 New Zealand Chinese families and found, as hypothesized, that brokering was significantly overrepresented in moderately (compared to high- or low-) acculturated families, and that brokers were mostly middle-aged parents. In the qualitative part of the study, detailed turn-by-turn analyses of brokering were conducted to reveal how brokering was occasioned, its subsequent enactment and eventual outcome. The results extend the understanding of unmediated communication accommodation in dyadic settings to mediated accommodation in group settings wherein a third (and sometimes a fourth) person brokers the accommodation. The resultant framework of brokered accommodation will be useful for research on other group conversations such as those involving a nurse brokering between a doctor and a patient.

Communication in the hospital setting: A survey of medical and everyday language use amongst patients, nurses and doctors

Forty physicians, 40 student nurses, and 40 hospital patiemts were surveyed regarding their usage and evaluations of medical and everyday language use in the hospital setting. Medical language (ML) and everyday language (EL) were operationalized as distinct speech registers that doctors, nurses and patients can use in their encounters with each other. A complex interaction of speaker characteristics (bilingualism in ML and EL) motivational factors (accommodation theory), situational language norms in favor of communicative effectiveness, as well as status and power differentials that exist between health setting. While doctors reported using mostly ML with health professionals, they did report converging to the EL of their patients. However, patients and student nurses did not perceive doctors converging to the EL of their patient. Student nurses reported using an equal mixture of ML/EL with each other, while converging to the ML of the doctor and converging to the EL of their patients. The ‘communication broker’ role of the nurse was corroborated by perceptions of nurses' language use from all groups. Patients reported using mostly EL with each other while attempting to converge to the ML of the health professional. Nurses perceived these attempts to converge by the patients, but doctors did not report a change in the patients' register as a function of conversants. Regarding the evaluation of language use strategies, all groups felt that it was more appropriate for health professionals to converge to the EL of patients than to maintain ML. In conversations with health professionals, patient use of EL was seen as more appropriate than ML. Use of ML by health professionals was felt to be a source of problems for patients, while EL was seen to promote better understanding for patients. The results are discussed with regard to the interplay of factors influencing language choice strategies in complex organizational structures such as hospitals.
