AgFAB - A Farmer-centered Agricultural Bower

Digital Agriculture aims to raise agricultural productivity while empowering the farming stakeholders (especially the farmers) with the availability of ICT-based applications on smart devices. However, despite putting in much effort, smallholder farmers’ willingness for adopting digital technologies is low in developing countries. In this study, following the principles of the human-design process, we investigated the smallholder farmers’ core demands from mobile/computing application(s). Considering these core demands of the farming community, the developed prototypical interfaces were evaluated by farmers using the System Usability Scale (SUS) to check the acceptability of a proposed farmer-centered solution named AgFAB. The AgFAB prototypical interface design received an average SUS score of 72.37, which is an indication of an acceptable design. Moreover, the results of Paired T-test seem promising for the strong adoptability of AgFAB by farmers with reference to their aspect of usability in the agricultural context.

Non-Small-Cell Lung Cancer Immunotherapy and Sleep Characteristics: The Crossroad for Optimal Survival

Non-small-cell lung cancer is still diagnosed at an inoperable stage and systematic treatment is the only option. Immunotherapy is currently considered to be the tip of the arrow as the first-line treatment for patients with a programmed death-ligand 1 ≥ 50. Sleep is known to be an essential part of our everyday life. We investigated, upon diagnosis and after nine months, 49 non-small-cell lung cancer patients undergoing immunotherapy treatment with nivolumab and pemprolisumab. A polysomnographic examination was conducted. Moreover, the patients completed the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), the Fatigue Severity Scale (FSS) and the Medical Research Council (MRC) dyspnea scale. Tukey mean-difference plots, summary statistics, and the results of paired t-test of five questionnaire responses in accordance with the PD-L1 test across groups were examined. The results indicated that, upon diagnosis, patients had sleep disturbances which were not associated with brain metastases or their PD-L1 expression status. However, the PD-L1 status and disease control were strongly associated, since a PD-L1 ≥80 improved the disease status within the first 4 months. All data from the sleep questionnaires and polysomnography reports indicated that the majority of patients with a partial response and complete response had their initial sleep disturbances improved. There was no connection between nivolumab or pembrolisumab and sleep disturbances. Upon diagnosis, lung cancer patients have sleep disorders such as anxiety, early morning wakening, late sleep onset, prolonged nocturnal waking periods, daytime sleepiness, and unrefreshing sleep. However, these symptoms tend to improve very quickly for patients with a PD-L1 expression ≥80, because disease status improves also very quickly within the first 4 months of treatment.

Effects of Smartphone Social Applications on Elderly People’s Quality of Life

As people age, maintaining and improving their Quality of Life becomes increasingly important. To understand the impact of smartphone technology and communications applications on Quality of Life, a quasi-experimental study was conducted with elderly people living in Shiraz-Iran. The study population included all the registered senior in public health centers in Shiraz, Fars, Iran during 2018 and 2019. Overall, 119 elderly people participated in the study. The study randomly categorized participants into intervention (59 participants with mean age 66.19±2.73) and control (60 participants with mean age 66.67±3.00) groups. They were asked to answer the validated Persian version of the Control, Autonomy, Self-realisation, Pleasure scale (CASP-19) scale questionnaire for Quality of Life assessment. A significant mean difference was observed by the paired t-test between pre-and post-test (t= -8.61, p<0.00), post-and follow-up-test (t= -2.24, p=0.02), and pre-test and follow-up test (t= -8.42, p<0.00) in the intervention group. The results of paired t-test for the control group showed no significant mean difference between pre-test and post-test (t= 1.35, p=0.18), post-test and follow-up test (t= 0.38, p=0.70) and pre-test and follow-up test (t= 1.94, p=0.06) for Quality of Life. The rationale for this study, along with the educational training associated with it, was to help families, and the aging field practitioners to understand the importance of modern communication technology teaching to promote a greater Life Quality in the community of the elderly.

The impacts of head trauma management education on the clinical decision-making of pre-hospital emergency staff.

The aim of this study was to compare the effectiveness of head trauma management education by the scenario method versus lecturing on clinical decision-making by pre-hospital emergency staff. This was an educational trial on 60 pre-hospital emergency staff, performed in Saveh in 2020-2021. The participants fulfilling inclusion criteria entered the study and were randomly allocated to two groups: scenario (n = 30) and lecture (n = 30). Clinical decision-making scores for head trauma patient management were determined at the beginning and end of the study using a researcher-made questionnaire. Data were analyzed using descriptive and inferential statistics and SPSS software version 16. At post-intervention, the mean score of clinical decision-making was 75.28 ± 11.7 in the scenario group and 68.55 ± 11.91 in the lecture group. The results of the independent t-test showed that the mean score of clinical decision-making was significantly higher in the scenario group compared with the lecture group (p = 0.04). The results of paired t-test showed a significant increase in the mean score of clinical decision-making in both groups after the intervention (p < 0.05); however, the mean of increment was higher in the scenario group (9.77 ± 7.63) than in the lecture group (1.79 ± 3). Regarding the impact of scenario-based education on learners' intellectual abilities and creativity, it seems that this type of education can be an appropriate alternative to traditional educational methods. Therefore, it is suggested to incorporate this method in the training programs of pre-hospital emergency staff.

Diurnal Variations of Exophoria in Subjects With Normal Vision

Background and Objectives: We aimed to investigate the variation of heterophoria during a day in students with a normal visual system. Methods: This cross-sectional observational study was conducted on 15 students aged 19 to 22 years with 20/20 visual acuity and normal binocular vision. Heterophoria was measured with a prism bar and alternate cover test at near and far distances (40 cm and 6 m). The measurement was performed from 8 to 10 PM in one day with 2 hours intervals. Results: The Mean±SD age of students was 21.6±0.87 years (63% women and 37% men). The mean deviation in far and near order was 1.93 and 3.75 prism diopter, respectively. The Greenhouse-Geisser test concluded no significant difference between the measurements of distant heterophoria during the day (F=1.362, df=3.066, P=0.267). However, the near-distance results were significant (F=15.17, df=7, P˂0.05). The paired t-test results showed that the highest amount of exophoria was observed near 4 PM, which was significantly different from the initial value, and the difference increases at the end of the day so that the mean difference of the initial near exophoria value from 4 to 10 PM reached from -1.254 to -3.508. Conclusion: Changes in refractive error or high order aberration increase near work and decrease the illumination during a day can induce force on accommodation and vergence. So, at the end of the day, the exophoria increases. Thus, it is preferable to perform eye examinations at the end of the day to make more accurate decisions about the diagnosis and treatment of patients.

2D-MOTION ANALYSIS: KNEE JOINT ANGULATION OF TRANSTIBIAL AMPUTEE PATIENT WHO USE SACH FOOT AT CLINIC LABORATORY OF PROSTHETICS AND ORTHOTICS DEPARTMENT IN POLYTECHNIC OF HEALTH MINISTRY OF HEALTH JAKARTA 1

The neutral foot position of the prosthetic SACH foot has a higher heel surface from the front of the foot (metatarsal line) with 1cm heel height. The prosthesis will be aligned to match the shoes that patient will use. When the patient is using shoes, the prosthetic SACH foot will be placed in a neutral position and will be supported by the shoe. When the patient does not use the shoe, the prosthesis will tilt backward especially when the foot is mid-stance and will force the pressure of the knee toward the extension of the knee joint which can cause damage to the knee joint structure. Therefore, knee joints will be measured at the time of the patient's use and not wearing shoes during mid-stance. Objective: To find out if there are significant differences in knee joint degree during mid-stance when using and not using shoes with 1cm heel height. Methods Quantitative comparative by observation of 2-dimensional motion in transtibial amputation patients using shoes and not using shoes with cross-sectional study design. Result : The degree of knee joints generated during mid-stance by patients with transtibial amputation when using shoes was 10.8o of flexion (p = 0.004) while at the time of not using the resulting knee boots was 4.5o of flexion (p = 0,000), normal degree of knee joint during mid- stance is 10o-20o of flexion. The results of paired t-test showed that there were significant differences in knee joint degree from standard degree, but when using the shoe showed a result of 0.8o larger than the lowest normal range while when not using shoes the resulting degree of 6.3o is smaller than lowest normal range.

The use of dimensional analysis for modeling tractor fuel consumption for harrowing operation

Fuel consumption model for predicting tractor fuel consumption per working area for harrowing operation has been developed using dimensional analysis. Generalized reduced gradient method of Excel solver was adopted for the establishment of the model’s constant. The model was validated by simulating the experimental results into the equation and coefficient determination (r2). Graphical comparison, root mean square error, and paired t-test were also use to validate. The field experiment was carried out at Rivers Institute of Agricultural Research and Training Farm in Rivers State University, Port Harcourt. The group balanced block design was adopted. The design consisted of 9 experimental treatments with three replicates. The experimental fuel consumption per working area was determined by quantity of fuel used per working area with the aid of fuel flow meter. The field test parameters were measured accordingly with their specific standard procedures. The field test parameters including bulk density, tractor forward speed, harrowing depth, and cone index were simulated with fuel consumption to obtain the constants in the prediction model. The developed model showed good agreement between measured and predicted results with high coefficient of determination and low root mean square error. The paired t-test results showed no significant difference at 95 and 99 % confidence levels. Thus, suggested that the model could be used for predicting tractor fuel consumption for harrowing operation.
