Telephone Calls

Telephone calls routed via satellite involve long transmission paths which in turn require significant transmission times even at the speed of light. This transmission time produces a delay in speech transmission of about 0.3 seconds in each direction for a synchronous satellite. Although the delay itself is not usually noticed by the talkers, it significantly increases the disturbing effects of echo and mutilation of speech by the echo suppressors so that the overall quality of the circuit, as judged by the users, suffers.

The theses reveal the problem of the connection between psychology and linguistics on the basis of translation activities. The role of the human factor of a translator is revealed, and the bonds between the type of translation and the characteristics of the person who does it is established For this purpose, a psycholinguistic experiment was carried out with the participation of 50 people to demonstrate the dependence of the psychological characteristics of the translator and the quality of the translated text using comparative analysis of translation. The data has confirmed the hypothesis about psychological phenomenon of translation.

Acoustic Conditions

  The acoustic quality of classrooms has a strong influence on the teaching and learning process. This interference assessed using the impulsive technique to measure the rate of speech transmission (STI), reverberation time (RT) and sound definition (D50). These are the most relevant acoustic descriptors in the assessment of classrooms, where verbal exposure is the means of communication between teachers and students. The evaluation took place in two buildings of the Federal University of Paraná (UFPR), built in the 1960s and another in 2016. The measured values ​​of STI, provided in the classrooms' actual acoustic conditions, were used as an adjustment parameter for simulations made with the software ODEON. After carrying out the measurements and simulations, the dimensioning of improvements was possible. The acoustic simulations presented suggestions to qualify the quality of the classrooms' acoustic comfort, ensuring that teaching and learning to do not suffer losses due to the physical structure of the classrooms. The measured values ​​of STI, RT and D50 show that, in the old building, except for a single classroom that preserves the original ceiling that had a high sound absorption coefficient, it has reasonable values, below the ideal for classrooms, according to the IEC 60268-16 (2011) standard. The investigation showed that the rooms with a roof replaced by a PVC covering had a sharp drop in acoustic quality. The newest building has classrooms with proper acoustic comfort conditions.

<em>The article is devoted to the analysis of the influence of the human factor on the corruption in the public authority. The corruption depends on the institutional quality of the public authority, its ability to withstand the negative manifestations of the human factor, and on the officials’ qualities. The motivation of “going to power” has a big significance. Under the authoritarian regimes, the corruption system is generated by the deformations in the election institution. The managerial lustration expediency for the power purification after the regimes’ changes is substantiated. The institutional measures to combat the corruption have been identified.</em>

This chapter presents a Model to Estimate the Human Factor Quality in Free/Libre Open Source Software (FLOSS) Development, or EHFQ-FLOSS. The model consists of three dimensions: Levels (individual, community, and foundation), Aspects (internal or contextual), and Forms of Evaluation (self-evaluation, co-evaluation, and hetero-evaluation). Furthermore, this model provides 145 metrics applicable to all three levels, as well as an algorithm that guides their proper application to estimate the systemic quality of human resources involved in the development of FLOSS, guide the decision-making process, and take possible corrective actions.

Business Process Management (BPM) brings together the idea of effectively managing organizations and properly using Information Technology to fulfill organizations’ needs. For this purpose, BPM systems are largely used nowadays. However, most process models are started from scratch, not having reuse promoted. Sometimes, large enterprises have the same business process implemented in a variety of ways due to differences in their departmental cultures or environments, even when using a unique integrated system. Additionally, although technology plays an important role in actually improving organizations, the human factor is still fundamental, since any improvement attempt goes through cultural changes. In this chapter, a peer-to-peer (P2P) tool is proposed as a way to cooperatively develop business processes models, minimizing the time needed to develop such models, reducing the differences among similar processes conducted in distinct organizational units, enhancing the quality of models, promoting reuse, and distributing knowledge.

Green Computing has attracted concerns in the past few decades, with the sole concern for the procedures involve in the designing, manufacturing, usage and disposal of information and communication technology (ICT) basically for environmental sustainability. The importance of human factor in green computing has not received the deserved attention. The social, moral and ethical decadence resulting from the use of ICT has reduced the quality of human in modern time. This study advocates the importance of peopleware as essential aspect of green computing which equalling demands concern. Thus the adoption of peopleware in green computing practices will invariably improve sustainability of the physical and spiritual environment.

Telephone Calls

Purpose: Patient care within radiation oncology extends beyond the clinic or treatment hours. The on-call radiation oncologist is often not a patient’s primary radiation oncologist, introducing the possibility of communication breakdowns and medical errors. This study analyzed after-hours telephone calls to identify opportunities for improved patient safety and quality of care. Methods and Materials: Patient calls received outside of business hours between July 1, 2013, and June 30, 2014, at two academic radiation oncology departments were retrospectively reviewed. All calls were analyzed using content analysis, and descriptive analyses were performed. Results: During this time, 5,557 courses of radiotherapy (RT) were delivered. A total of 454 calls were received from 369 unique patients (81%), averaging 4.4 calls per week per department. Phone encounters were documented for 223 calls (49%). The calls were categorized by disease site (No., %): central nervous system (91, 20%), head and neck (78, 17%), genitourinary (53, 12%), GI (52, 12%), thoracic (51, 11%), gynecologic (30, 7%), breast (24, 5%), and other (75, 17%). Patients most often called regarding acute medical, non–RT-related issues (144 calls, 32%); acute RT-related adverse effects (127, 28%); and medication management, including refills (63, 14%). Conclusion: This analysis provided novel information regarding the volume of and reasons for after-hours patient-initiated telephone calls. It identified opportunities for actionable improvements in safety and quality of care, particularly with regard to documentation by on-call providers, communication with the primary radiation oncology and extended health care teams, patient education about common RT adverse effects, and medication management.

Scientific Approach

This paper discusses the use of the interpolation method for the sequential calculation of the Fourier spectrum (IMSCS) for retouching and restoration of missing (shaded) image fragments. The proposed approach can be used with any form of a missing image fragment. Such image processing can give good results even at a significantly high percentage of missing image fragments. The method of digital virtual image reconstruction proposed here is strictly based on a scientific approach; as the source data, it uses all the data available (the image itself is the object to be recovered). Therefore, it is free from the human factor, because of which subjective changes can be introduced in the image under processing. The results presented indicate a significant increase in the quality of digital images (increasing the information content), which can offer helpful auxiliary tools for professionals using these images for their practical purposes.
