A Research on Modulation in Digital Communication System

With the development of network and communication technology in modern society, WiFi technology has become an indispensable part of people’s lives. WiFi shows its future application prospects with its wireless portability and multi-user access. This paper briefly introduces the meaning and development of WiFi technology and predicts its future development trend. The communication modulation technology QPSK, 16QAM in WiFi is described in detail, and its characteristics are compared by systemview and MATLAB software. Finally, we summarize the common techniques in WiFi.

Hybrid presence: Integrating interprofessional interactions with digital consultations

Healthcare practitioners struggle to adapt to the changes that new digital media entail for social interactions, but what does the struggle look like, and how is it embedded in these professionals’ everyday experiences? I investigate these questions in this study of how digitalisation conditions social interactions in the context of the Danish medical setting by drawing on ethnographic work. Moreover, via a video-recorded case study, this article shows how two practitioners organise social actions by exploiting features of a digital communication system in a situation where they manage a practical problem. I propose the concept of hybrid presence related to the scientific fields of dialogism and distributed cognition as an explanation of how the participants are capable of immersing themselves with both the digital technology and the social interaction. Hybrid presence thus proves useful in the discussion of how practitioners may struggle with technology.

Electromagnetic Radiations on the Functional Potential of Spermatozoa

The growing exposure to digital communication system and tools leads to radiation toxicity to the users. Unaware of the safety measures even a kid at the age of one starts operating digital gadgets emitting Radio frequencyelectromagnetic radiations. Radiations from mobile phones laptops, note pad, Wi-Fi or other devices are reported to be harmful beyond the permissible limit. So there is a growing concern for the overall health, reproductive, and hormonal functions. Experimental studies were conducted by using a Wi-Fi network active laptop and live spermatozoa. The exposure of sperms to the source of EMF showed that the activity of the live sperms got reduced and mortality was observed depending on the exposure duration and the distance from EMF sources. After 5h of exposure to RF-EMF source the semen quality changed when compared with control. The vitality of sperm in the control was 95±1.0 after 2 hr and it was reduced to 60±1.5 percent at a distance of 1cm and 55±2.2 percent at a distance of 10 cm. After 5 hour exposure, the vitality was reduced to 63±1.86 at 1 cm distance and 70±1.42 at 10 cm distance. The reduction in vitality of sperm after exposure to RF-EMF source for 2 hour was 35% at 1cm and 40% at 10cm distance.

Health Care Professionals’ Experience of a Digital Tool for Patient Exchange, Anamnesis, and Triage in Primary Care: Qualitative Study

Background Despite a growing body of knowledge about eHealth innovations, there is still limited understanding of the implementation of such tools in everyday primary care. Objective The objective of our study was to describe health care staff’s experience with a digital communication system intended for patient-staff encounters via a digital route in primary care. Methods In this qualitative study we conducted 21 individual interviews with staff at 5 primary care centers in Sweden that had used a digital communication system for 6 months. The interviews were guided by narrative queries, transcribed verbatim, and subjected to content analysis. Results While the digital communication system was easy to grasp, it was nevertheless complex to use, affecting both staffing and routines for communicating with patients, and documenting contacts. Templates strengthened equivalent procedures for patients but dictated a certain level of health and digital literacy for accuracy. Although patients expected a chat to be synchronous, asynchronous communication was extended over time. The system for digital communication benefited assessments and enabled more efficient use of resources, such as staff. On the other hand, telephone contact was faster and better for certain purposes, especially when the patient’s voice itself provided data. However, many primary care patients, particularly younger ones, expected digital routes for contact. To match preferences for communicating to a place and time that suited patients was significant; staff were willing to accept some nuisance from a suboptimal service—at least for a while—if it procured patient satisfaction. A team effort, including engaged managers, scaffolded the implementation process, whereas being subjected to a trial without likely success erected barriers. Conclusions A digital communication system introduced in regular primary care involved complexity beyond merely learning how to manage the tool. Rather, it affected routines and required that both the team and the context were addressed. Further knowledge is needed about what factors facilitate implementation, and how. This study suggested including ethical perspectives on eHealth tools, providing an important but novel aspect of implementation.
