Recently, the beneficial effects of the plants' secondary compounds for the treatment and improvement of diseases have been strongly interested. This study was conducted in a completely randomized design with three replications in the Paveh and Ormanat region of Kermanshah province. For this purpose, after studying the flora of the region, 10 high-widespread families (Apiaceae, Boraginaceae, Lamiaceae, Rosaceae, Solanaceae, Polygonaceae, Fabaceae, Brassicaceae, Liliaceae, and Asteraceae) were selected. In each case, three plant species with three replications were identified and randomly collected during flowering from April to September. Antioxidant potentials of the samples were evaluated by four methods of DPPH, FRAP, ABTS, and TAC. Results of analysis of variance showed significant differences between measured traits in plant species as well as plant family with 99% confidence. Among the studied plants, Pimpinella kotschyana Boiss. from Apiaceae, Bellevalia dichroa Hausskn. from Liliaceae, Muscari neglectum Guss, from Liliaceae showed the highest antioxidant activities using different methods. Results also showed that among the studied plant families, Liliaceae, Rosaceae, Brassicaceae, and Asteraceae showed considerable antioxidant potential and could be noticed in future research.

Medicinal plants have wide diversity and the amounts of active compounds of them are highly variable in different areas of Iran. These changes can be depending on the plant species and environmental conditions such as temperature, precipitation and elevation or soil conditions. Therefore, evaluation the medicinal plants of an area can play an important role in understanding the potential of medicinal plants.

In this experiment, 348 plant samples were collected from 116 medicinal plants in Paveh and Ormanat. The samples were tested after identification in herbarium laboratory of Razi University of Kermanshah and were transferred to the laboratory of Department of Horticultural Sciences of Gorgan University of Agricultural Sciences and Natural Resources for antioxidant potency analysis. After preparation the herbarium samples, the plants were dried in shade as thin layer. The dried samples were employed to measure total antioxidant potential (TAOC) via TAOC method. Furthermore, climate data and soil chemical parameters were collected. To prepare the TAOC reagent, 0.6 mM sulfuric acid (H2SO4), 28 mM sodium phosphate (Na3PO4) and 4 mM ammonium molibdat (N6H24Mo7O24) were used. Finally, the relationship between them and TAOC was evaluated using regression models by data mining.

In order to assess the effect of environmental parameters on the total antioxidant content of medicinal plants in this study, the correlation between data was evaluated. The results showed that there is no correlation between environmental parameters and TAOC. In data analysis, the two-variable regression equations did not show satisfactory results, as in the stepwise method, a maximum of 31% correlation was observed, but the M5 tree regression model by dividing the data into 29 spaces provided the TAOC values which showed 91% correlation and RMSE = 16.6%.

The results of our study showed that, the amount of antioxidant capacity of plant based on total antioxidant had no significant correlation with environmental and soil conditions. Moreover, its multivariate relationship did not show a significant correlation, which could be due to the high diversity in the studied species. It concluded that in addition to genetic potential, total antioxidant activity of medicinal plants depends on the environmental and climatic conditions. However, understanding the potential of medicinal plants with multiple environmental and genetic parameters using data mining techniques is an important trait. Overall, the results of this study showed that,in present study the M5 decision tree method was an efficient method in evaluation of antioxidant capacity of plant.

One of the most important factors in the proper functioning of the military is the accurate assessment of feedback. Among these, the proper knee joint proprioception is one of the most important factors in this regard. This study was performed to evaluate knee joint proprioception changes in military forces following a period of a static and dynamic stretching of hamstrings, quadriceps and gastrocnemius muscles.

The study was semi-experimental. The population of the study included the men AJA air defense base of Khatam al-Anbia (PBUH), among which, 60 individuals were randomly divided into three groups of 20; Static (height: 173.27, Weight: 78.14), Dynamic (Height: 175.08, Weight: 76.92), and Control (Height: 176.12, Weight: 80.09). The subjects in both groups of static and dynamic stretching performed their group-specific stretching programs. The goniometric method of digital images was used to measure the knee joint proprioception using AutoCAD software. One-way variance analysis test and paired t-test were used for results. The significance level in the present paper was considered to be 95% (α≤0.05) (SPSS 22).

The results of the knee joint proprioception variables showed a significant difference with the control group (slight increase), between the static groups (decrease, p=0.05) and the dynamics (decrease, p=0.004). There was also a significant difference in the measured variables in the in-group comparison in the static group (decrease, p=0323) and dynamics (decrease, p=0.002). (Reducing the absolute error values of the target angle reconstruction and, consequently, improving the knee joint propensity sensitivity).

Static and dynamic stretching exercises in the lower extremity can possibly affect muscle spikes, increase muscle temperature, trigger the activation phenomenon, repeat the movement in a specific pattern, and ultimately the phenomenon of post-traptional sensory drainage, increase the sensitivity of muscle receptors and ultimately improve the sense of knee joint condition. Since any proprioception sense of depression can lead to mechanical instability and ultimately cause the joint to be prone to mild blows and ultimately damage, stretching exercises may also change the muscle spindle properties and increase the knee proprioception. Also, dynamic stretching improves the ability to perform better in the knee joint proprioception variable relative to static stretchinglearning of nursing students as well as accepting responsibility professionals in medical sciences.
