Every year thousands of the elderly suffer serious damages such as articular fractures, broken bones and even death due to their fall. Automatic detection of the abnormal walking in people, especially such accidents as the falls in the elderly, based on image processing techniques and computer vision can help develop an efficient system that its implementation in various contexts enables us to monitor people’s movements. This paper proposes a new algorithm, which drawing on fuzzy rules in classification of movements as well as the implementation of the motion estimation, allows the rapid processing of the input data. At the testing stage, a large number of video frames received from CASIA, CAVAIR databases and the samples of the elderly’s falls in Sabzevar’s Mother Nursing Home containing the falls of the elderly were used. The results show that the mean absolute percent error (MAPE), root-mean-square deviation (RMSD) and standard deviation error (SDE) were at an acceptable level. The main shortcoming of other systems is that the elderly need to wear bulky clothes and in case they forget to do so, they will not be able to declare their situation at the time of the fall. Compared to the similar techniques, the implementation of the proposed system in nursing homes and residential areas allow the real time and intelligent monitoring of the people. تفاصيل المقالة

2 - اثربخشی گروه درمانیِ مبتنی بر بخشش بر علائم افسردگی و نشانگان آشفتگی روانی در زنان سالمند
پروانه محمدخانی

چکیده: مطالعه حاضر در چارچوب طرح شبه آزمایشی با دو گروه آزمایش و کنترل، انجام پیش آزمون ـ پس آزمون، و پیگیری 3 ماهه انجام شد. جامعة آماری پژوهش را زنان سالمندی تشکیل می دادند که پیش از اجرای پژوهش به فرهنگ سرای امید شهر تهران مراجعه کرده بودند. از این جامعه آماری به ت أکثر

چکیده: مطالعه حاضر در چارچوب طرح شبه آزمایشی با دو گروه آزمایش و کنترل، انجام پیش آزمون ـ پس آزمون، و پیگیری 3 ماهه انجام شد. جامعة آماری پژوهش را زنان سالمندی تشکیل می دادند که پیش از اجرای پژوهش به فرهنگ سرای امید شهر تهران مراجعه کرده بودند. از این جامعه آماری به تصادف، نمونه ای به حجم 30 نفر انتخاب گردید که به طور تصادفی، در دو گروه آزمایش (N=15) و کنترل (N=15) جای داده شدند. هر دو گروه با استفاده از پرسشنامه افسردگی بک (نسخه 2) (BDI-II) و پرسشنامه نشانگان مختصر (BSI) مورد ارزشیابی قرار گرفتند (پیـش آزمـون). سپـس، گـروه آزمـايـش تـحت 8 جلسـه هفتگی 2 ساعتة درمـان گـروهی بخشـش قـرار گـرفت و گروه کنترل مداخله ای دریافت نکرد. از هر دو گروه، پس آزمون با هر دو آزمون و ارزشیابی پیگیرانه 3 ماهه فقط با استفاده از پرسشنامه بک به عمل آمد. نتایج حاکی از کاهش افسردگی در گروه آزمایش بود (p<0.05). همچنین، نتایج تحلیل داده های مربوط به پرسشنامه نشانگان مختصر گویای تفاوت معناداری بین دو گروه در خرده مقیاس های آن و سه شاخص شدت کلی آشفتگی روانی، کل نشانه های مثبت، و شاخص نشانه های مثبت آشفتگی روانی بود (p<0.05). برمبنای این یافته ها، می توان گفت درمان گروهیِ مبتنی بر بخشش در کاهش نشانگان افسردگی و سایر نشانگان آشفتگی روانی که ممکن است با رنجش های بین فردی گذشته سالمندان ارتباط داشته باشند، مؤثر است و برای ارتقاء بهداشت روانی این مرحله از عمر بشر مفید واقع می شود تفاصيل المقالة

Background: Changes in the human body due to the aging process, especially the loss of strength and flexibility of the lower limbs can increase the risk of falls. The aim of this study is to compare the effect of selected Pilates, Pilates with Traband and Pilates exercises with both factors such as strength and flexibility of the lower extremities of non-athlete 50-60 years old. Materials and Methods: Thirty participants in this study have been randomly divided into three groups: quasi-experimental, Pilates (10), Pilates Traband (10) and Pilates (10). Before the beginning of the exercises, the strength of the lower limbs and static acceptance and the range of motion of extension and flexion of the thigh have been measured using the test of 30 sitting on a chair, static acceptance and goniometer, respectively. Moreover, all three groups as participated in a course of exercise. These exercises have performed for 8 weeks, 3 sessions per week for 1 hour and have performed after the participants. Data have been analyzed using paired t-test and ANOVA. Results: As result, all three groups show the significant progress due to exercise but there is not any significant variance between the groups, as none of the methods is not better than other training methods. Conclusion: performing Pilates exercises, Weight and Traband based on the availability of training equipment and facilities, is beneficial for the elderly, and this exercise may reduce the negative physical consequences and consequent treatment costs, and helps to slow down the aging process and is effective in improving the daily activities of the elderly. تفاصيل المقالة

Background: Considering the significant increase in apoptosis in the elderly, which is related to cardiovascular diseases, cancer, etc. The purpose of this research was to investigate the effect of eight weeks of aerobic exercise on some factors of apoptosis in elderly men was investigated. Materials and Methods: This research was conducted using a semi-experimental method with 30 healthy elderly men aged 60 to 75 years. who voluntarily participated in this research project and were randomly divided into two experimental (15 people) and control (15 people) groups. The experimental group participated in aerobic exercises for 8 weeks (three sessions of 1 hour per week) based on the special recommendations of the American College of Sports Medicine (ACSM) for the elderly. The control group did not have any physical activity during this period. Serum caspase-8, P53 and IGF-1 were measured by ELISA method. Dependent t-test and independent t-test were used to check the intra-group and inter-group differences of variables. Data analysis was done using SPSS version 20 software and the significance level was considered p≤0.05 in all steps. Results: The results showed that eight weeks of aerobic exercise increased the serum levels of caspase 8(P=0.0001) and decreased the serum levels of P53(P=0.0001) and IGF-1(insulin-like growth factor) (P=0.0001). Conclusion: According to the findings of the present research, it seems that eight weeks of aerobic exercise significantly increases the serum levels of caspase 8 and decreases the serum levels of P53 and IGF-1 in elderly men. According to these results, more research is needed in this field. تفاصيل المقالة

Background: Diabetic cardiomyopathy refers to changes in the heart as a result of impaired glucose homeostasis, leading to ventricular dysfunction and associated with mitochondrial dysfunction. Since sports activity is known to protect the heart, the aim of the present study was to investigate aerobic exercise and the effective substance crocetin on the expression of Myod gene in the heart tissue of an experimental model of elderly prediabetic rats. Materials and Methods: In this experimental trial, 25 elderly female c57bl6 male mice with prediabetes (20 mg/kg peritoneal injection) aged 14-16 weeks and weighing 30-35 grams were divided into 5 healthy control groups, prediabetic, prediabetic + aerobic exercise, pre-diabetic + crocetin, pre-diabetic + aerobic exercise + crocetin were divided. aerobic training was performed for eight weeks, five sessions per week. Mice received crocetin 30 mg/kg/day by intraperitoneal injection. Myod expression was measured by Real Time PCR method. To analyze the data, one-way analysis of variance and Tukey's post hoc test were used (P≥0.05). Results: Myod gene expression was significantly decreased in the prediabetic group compared to the healthy group (P=0.01). Myod gene expression was significantly higher in the pre-diabetes group + aerobic exercise + crocetin supplement and diabetes group + aerobic exercise + crocetin supplement than other groups (P=0.01). Conclusion: It seems that intermittent aerobic exercise and crocetin both alone and simultaneously are effective in improving Myod gene expression in prediabetic heart tissue. Therefore, the use of periodic aerobics and crocetin n is recommended in pre-diabetes conditions of old age تفاصيل المقالة
