(THIS PAPER NEEDS A CORRECTION) Satisfaction is a complex concept which has a key role in each individual’s everyday life and impacts their behavior. Abraham Maslow (1943) suggested a framework [1] to study human motivation, which was a starting point towards developing the quality of life(QOL) theory. On that article, he described a hierarchy of human needs, that is generally consist of fundamental needs which are required for human survival, and environment dependent ones, like society, safety and etc. In this (...) study, we are trying to represent a tangible mathematical model for assessing the sense of need for water in terms of the available source of water. On this very subject, M. Joseph Sirgy [2] states that ”From a human developmental perspective, QOL goals can be defined as satisfaction of human developmental needs in a community or society”. Accordingly, in the first section we propose a model for the water needs of an individual. In the second section, we continue the discussion by checking the behavior of the model on a given population, and each time by assuming that we have two out of three involved factors, we try to suggest an estimation for the other one.

Vibration, especially basic vibration, may cause loose contacts, open circuits, or other contact problems, which account for a large proportion of system failure causes. Due to the complexity of the chassis structure used in the biomedical motors, the vibration analysis of a single component cannot solve the vibration problems encountered in the work of the system. Therefore, it is necessary to use system simulation and experiments to monitor and enhance the health of the structure. Finite element method is used to (...) carry out the dynamic analysis from the component to the system, and calculate the natural frequency, modal shape and harmonic response. Then, the effectiveness and accuracy of the analysis results are verified by experiments through simulation and experiments. The results show that the measures taken have effectively reduced the vibration of the chassis equipment and improved its safety for better health safety of patients. There is just a 2% variation between the natural frequencies acquired from the experiment and the simulation computation. In terms of natural frequency, the first 6-order natural frequencies all have errors of less than 10%, and the natural frequency error is comparable to that of fireproof board. (shrink)

Objectives: To explore individuals’ perception of the personal, family and societal educational needs following a spinal cord injury. Methods: Sixty-one patients who sustained a traumatic SCI between March 2015 and June 2016 referred to Brain and Spinal Cord Injury Research Center were included in a cross sectional study and completed an online survey containing open-and closed-ended questions, in Iran. Participants’ responses were analyzed i using a qualitative approach with a thematic analysis. Results: Following a thematic analysis of the patient’s perceived (...) educational needs, 3 themes and 14 subthemes were identified. The 3 themes included personal, family, and societal educational perceived needs. Within personal educational needs, there were 7 subthemes which included personal independence and transportation, financial independence, life skills modification, knowledge about SCI, prevention of SCI complications, relationships and sexual function, and psychological adjustments. Among family educational needs, the 3 subthemes were caregiver skills and communication, first aid and emergency skills, and emotional and psychological support. For societal educational needs, the 4 subthemes described were social integration, interpersonal communication skills, SCI awareness and injury prevention, sympathize while avoiding pity. Conclusion: According to our findings, people with SCI have various needs that need to be addressed. Educational support should be a part of a comprehensive rehabilitation program and geared towards addressing the patients’ personal and family needs, while educating the community about SCI in order to allow for reintegration into society.
