In architectural education, generally experience is the most permanent way to learn professional skills. However, perhaps as a result of modern education, it is not possible to learn everything about the building by experience. SimYA project aims to help the development of a new generation construction studio based on learning by doing and experiencing in architectural education by using virtual reality (VR) technologies. Within the scope of the project, an interactive VR-based computer simulation (SimYA) developed to demonstrate basic construction elements such as foundations, walls, and roofs. The effectiveness of the SimYA against the traditional method has been tested with a scientific experiment. A total of 32 volunteer architecture students participated in the experiment. The participants were divided into two equal groups within the scope of the experiment. These groups were named as SimYA and control group in a way to be compatible with their related method. First, a pre-test was applied in order to evaluate the current knowledge of the groups. After that, the first group was taught with the VR supported SimYA program and the second group was taught with the traditional method. According to test results, the success rate of the SimYA group increased from 5.63% to 74.86%, and the success rate of the control group increased from 3.12% to 57.95%. These results indicate that the SimYA project has achieved the targeted success. It is thought that placing the building elements and materials in the virtual environment with student’s own hands and receiving visual and audio information from the interactive building elements are an important factor in this success.

SUMMARY OBJECTIVE: This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers. METHODS: The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS). RESULTS: We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p<0.001). CONCLUSION: This study found that the use of virtual reality was effective in reducing the level of pain in healthy individuals. This method used a smartphone with widespread availability and ease of transportation, which can be used by health professionals as a non-pharmacological method in the management of pain.

The aim of the study was to investigate the efficacy of electro-acupuncture coupled with conventional treatments and compare it with the efficacy of conventional treatments alone in patients with chronic plantar fasciitis. Thirty patients with chronic refractory plantar fasciitis were randomly assigned to two groups. Subjects in the control group received five weeks of conventional treatments, including stretching exercise, shoe modification and rescue analgesics. Subjects in the acupuncture group received the same treatments plus ten sessions of electro-acupuncture twice weekly. Endpoints included a success rate determined by a minimum of a 50% decrease in Visual Analog Scale (VAS) and Foot Function Index (FFI). At the end of treatment, VAS decreased significantly from 6.00 ± 1.69 to 1.89 ± 1.59 and from 6.27 ± 2.34 to 5.40 ± 2.26 in the acupuncture and control groups, respectively. FFI decreased significantly only in the acupuncture group (p < 0.05). Subjects in the acupuncture group obtained higher success rates than those in control group (80% and 13.3%, respectively). FFI in the acupuncture group was better than those in the control group (p < 0.001). At the sixth week follow-up, subjects in the acupuncture group showed a better FFI and success rate for pain during the day than those in the control group (p < 0.05). Electro-acupuncture coupled with conventional treatments provided a success rate of 80% in chronic planar fasciitis which was more effective than conventional treatments alone. The effects lasted for at least six weeks.

The objective of this research exercise is to examine how reciprocal teaching affects 7th-grade students reading motivation in the subject of English. To meet the desired objective, the study employed a quasi-experimental design. The intact classes were randomly allocated to the experimental and control group. The experimental group was instructed with reciprocal teaching strategies, while the control group was taught with the traditional method. The Motivations for Reading Questionnaire (MRQ) was administered before and after the intervention. The study employed Pretest-Posttest Nonequivalent Control Group Design for data collection. The data was analyzed using the independent sample and paired sample t-test. The results of the study revealed that the motivation level of students who were taught with reciprocal teaching is significantly higher than those students who were taught with the traditional method. These results suggest that reciprocal teaching should be incorporated in teacher education programs as appropriate instructional practice for reading.

Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation between the etiology of hearing loss (HL) and a possible damage to the labyrinth. Methods A case-control retrospective study was performed. In the case group, 20 adults with MPSHL of known etiology were included. The control group was composed of 15 adults with normal hearing. The case group was divided into 4 subgroups based on the etiology (bacterial meningitis, virus, vascular disease, congenital). Cervical vestibular-evoked myogenic potentials (cVEMPs) were used to rate the saccular function and lower vestibular nerve. Results The study was performed in 70 ears, and it highlighted the presence of early biphasic P1-N1 complex in 29 (71.5%) out of 40 ears in the study group, and in all of the 30 ears in the control group (p = 0.001). Regarding the presence or absence of cVEMPs among the four subgroups of patients with MPSHL, the data were statistically significant (p < 0.001). The comparison between the latencies and amplitude of P1-N1 in case and control groups from other studies and in the four subgroups of cases in the present study did not detect statistically significant differences. Conclusion The present study demonstrates that patients with MPSHL have a high incidence of damage to the labyrinthine organs, and it increases the current knowledge about the etiopathogenesis of sensorineural HL, which is often of unknown nature.

The high increase of electronic media supported by internet resulted in accessing all information easily. Concurrently, the requirement of thinking critically intrigued all parties to be involved in the internet environment. This research aimed at investigating whether or not there were significant mean differences of critical thinking ability in writing exposition text between students who were taught by using E-writing method and those who were given traditional method of writing. The study employed quantitative paradigm design with the type of quasi experimental and involved students which was selected purposively and formed into experimental group and control group. The primary data was the result of pre-test and post-test in the form of essays which were scored by the Holistic Critical Thinking Scoring Rubric (HTCR) developed by Facione & Facione (2011). Based on the result of pre-test and post-test, NGain was analyzed through Man Whitney test to find out the significant mean different of students’ critical thinking ability. After being analyzed by using SPSS 23, the Mann Whitney test came up with the accepted hypotheses i.e., there were significant mean differences of critical thinking ability between experiment group and control group, with mean of NGain score for experimental group was higher than control group had. The statistical output of Mann Whitney test obtained implied that students’ critical thinking ability were influenced by E-writing method. The result of the study convinced that E-writing contributed greater improvement in students’ critical thinking ability than the traditional method did. The finding of present study provided evidence for the effectiveness of E-writing in increasing the students’ ability in thinking critically in writing exposition text.

BACKGROUND Cardiac rehabilitation is clinically proven to reduce morbidity and mortality, but many patients do not attend treatment. Those who do attend frequently do not finish their full course of treatment. This is greatly influenced by socioeconomic factors but is also due to patients’ lack of understanding on the importance of their care and a lack of motivation to maintain attendance. OBJECTIVE The goal of this study was to explore the potential benefits of virtual reality (VR) walking trails within cardiac rehabilitation treatment, specifically on patient education retention, satisfaction with treatment, and overall attendance of treatment sessions. METHODS New cardiac rehabilitation patients were enrolled and randomized on a rolling basis to either control or intervention groups. Intervention patients completed time on the treadmill with VR walking trails, including audio recorded education; control patients completed standard of care therapy. Both groups were assisted by nursing staff for all treatment sessions. Primary outcomes were determined by assessing six-minute-walk-test (6MWT) improvement. Additionally, secondary outcomes of patients’ cardiac knowledge and satisfaction were assessed via computer-based questionnaire; patient adherence to recommended number of sessions was also monitored. Cardiac knowledge assessment included a pre-rehabilitation education quiz, the same quiz repeated at their final visit, and again at a 2-month follow up. The satisfaction questionnaire was completed at their final visit. RESULTS Between January 2018 and May 2019, 72 patients were enrolled, 41 to the intervention group and 31 to the control group. Based upon the results of the pre- and post-rehabilitation 6MWT, no differences were seen between intervention and control groups (P = .23). No statistical differences were seen between groups on education (P = .50) or satisfaction (P = .30) at any time point. The control group had statistically more favorable rates of attendance, both by risk group (P = .024) and by completion of minimum sessions (P = .046), but no correlation was seen between study group and reason for ending treatment. CONCLUSIONS While no improvements were seen in the VR intervention group over the control group, it is worth noting that limitations in the study design may have influenced these outcomes, not the medium itself. Furthermore, qualitative information suggests that patients may have indeed enjoyed their experience with VR in a way that the quantitative data in this study may not have captured. Suggested within this paper are further considerations of how and when VR should be applied to cardiac rehabilitation. CLINICALTRIAL ClinicalTrials.gov NCT03945201

Purpose. To evaluate the effect of preoperative intravitreal bevacizumab (IVB) injection on the surgical outcome of Ahmed glaucoma valve (AGV) implantation according to the angle status in neovascular glaucoma (NVG) eyes. Materials and Methods. This retrospective study included 70 NVG patients who underwent AGV implantation and were followed up for at least 12 months. An IVB injection before AGV implantation was administered to 45 eyes (IVB group), while it was not administered to 25 eyes (control group). Subgroup analyses were done at different stages in terms of the extent of peripheral anterior synechiae (PAS). Results. Mean follow-up period after AGV implantation was 27 ± 15 months. The IVB group showed higher prevalence of the eyes with less than 50% of PAS than that of the control group (78% versus 44%). The overall success rate 1 year postoperatively was 80% and 64% for the IVB and control groups, respectively (P=0.142). When PAS extent was less than 50%, preoperative IVB had a marginally positive effect on surgical outcome (HR = 0.39, P=0.064, per 1-time IVB injection). Conclusions. Preoperative IVB may enhance the success rate of AGV implantation in NVG eyes, before PAS has extensively formed. Further prospective randomized studies controlling the extent of PAS are warranted.
