This study identified the readiness factors that may create challenges in the use of telemedicine among patients in northern Louisiana with cancer. To identify these readiness factors, the team of investigators developed 19 survey questions that were provided to the patients or to their caregivers. The team collected responses from 147 respondents from rural and urban residential backgrounds. These responses were used to identify the individuals’ readiness for utilising telemedicine through factor analysis, Cronbach’s alpha reliability test, analysis of variance and ordinary least squares regression. The analysis results indicated that the favourable factor (positive readiness item) had a mean value of 3.47, whereas the unfavourable factor (negative readiness item) had a mean value of 2.76. Cronbach’s alpha reliability test provided an alpha value of 0.79. Overall, our study indicated a positive attitude towards the use of telemedicine in northern Louisiana.

Aim: This research was conducted with the aim to determine the validity and reliability of the Turkish version of the Solid Waste Management Scale in health institutions. Method: The study population consisted of nurses working in two different hospitals (918 + 939 = 1857 nurses). The samples were selected from the universe using the improbable sampling method. The data were collected by a Personal Information Form and the Solid Waste Management Scale in Healthcare Institutions. The data were analyzed based on the computations of descriptive statistics including mean, standard deviation, frequencies, percentages, Cronbach’s alpha reliability coefficient, Pearson Product Moments Correlation, Factor Analysis, Bartlett’s Test, and Kaiser-Meyer-Olkin Test. Results: The content validity index of the scale was found to be 0.98. The Cronbach’s alpha reliability coefficients of the scale ranged between 0.59, and 0.73, while the item factor loads between 0.31, and 0.94, and the item-total correlation values between 0.21, and 0.77. The factorial structure of the scale was confirmed as a result of the Exploratory and Confirmatory Factor Analyses. Conclusion: The Turkish version of the Solid Waste Management Scale in Health Institutions showed that it is a valid and reliable tool for determining the level of knowledge and attitudes of nurses working in health institutions about solid waste management. This scale, whose validity and reliability has been tested, can be used to determine the attitudes and knowledge levels of nurses working in health institutions on solid waste management.

Different Shapes

Hands are important tools for manual work. Although researchers have identified factors that influence the grip efforts of an entire hand, there appears to be limited research concerning the use of different pinch techniques and how they affect the performance of pinch effort. Therefore, the aim for this pilot study is to determine the effects of different pinch techniques on pinch effort. A total of 110 manual workers from a wooden pallet manufacturing firm participated in this study, which involved an experiment and survey to investigate the most preferred pinch technique applied on screw knobs. The techniques used were the 3-jaw chuck, pulp-2 and lateral pinch. A total of 6 screw knobs of different shapes and sizes were used. After the data were collected, descriptive and Cronbach's alpha reliability analyses were carried out. The results show that the preferred pinch technique for the small cylindrical knob, small sphere knob and all large knobs is the lateral pinch. However, the 3-jaw chuck pinch is preferred for the small 5-lobes knob. This study provides preliminary information for further research on pinch techniques and their influences on the pinching outcomes of individuals.
