Volume 2, Issue 2 (Spring 2022)
Abstract

Heidegger believes that among the Greeks, Aletheia means "Unhiddeness," which is an essential attribute for beings. However, by referring to the world of ideals, Plato considers Truth as conformity and transfers it to human reason. In this approach, the truth lost its intrinsic character and became the correspondence of cognition with its objective reference. This epistemological transformation led to the emergence of prevalent dualities in philosophy. Although Mulla Sadra has fundamental similarities with Heidegger, he considers truth to have multiple meanings by gradation. In the third phase of his philosophical thought, by reaching divine manifestation -with his special interpretation of Platonic philosophy- he abandons his earlier conventional dichotomies in philosophy. At this stage, Mulla Sadra reaches Real Unity and accepts Plato's truth as something with existential gradation. In this paper, we are trying to examine the views of Heidegger and Mulla Sadra while briefly analyzing the truth of Plato. Finally, we will extract Sadra's criticisms of Heidegger's thoughts about truth.

Abstract

In this study, first using documentary research method, the nature of language in the web-based electronic communication, besides different methods of improving communicative and linguistics competence in teaching languages online, were investigated. Then considering the importance of language faculties' familiarity with the role of computer-based teaching in the development of linguistic competence and communicative skills necessary for translating or teaching all foreign languages (esp. Persian to non-natives), a descriptive survey method was used to investigate the familiarity of foreign language faculties with the strategies and technologies used in e-teaching-learning process applied in teaching languages online. The results of the 68 questionnaires filled in by English, French, German and Persian faculties of seven universities offering classical and virtual programs indicated that most of language faculties are not familiar with web-based strategies and techniques in teaching or learning foreign languages. Considering the need of our country for the experts who are able to communicate with the scientific scholarly networks in the world to obtain or transfer related knowledge and those who are able to use at least one international language of their fields thoroughly, planning an online faculty training program can be an essential measure to improve teaching or translating foreign languages at the academic level and also lead Persian language to find its proper position in the cultural, educational and scientific world networks.

Volume 9, Issue 3 (Summer 2021)
Abstract

Aims: In this study, sediment size distribution and its statistical properties are studied in the rip channel, and its surroundings in the Royan marine ecosystem lied in the southern part of the Caspian Sea.  
Materials & Methods: Three rip current channels were selected every eight investigating months. Sediment samples were collected from inside each rip channel and its surrounding areas. The statistical indices, viz., D50, mean, skewness, and sorting, have been calculated for sediment grain size parameters. Finally, a general linear model and unpaired t-test were used to perform statistical comparisons of grain size characteristics between the rip channel and its surrounding area.
Findings: In May, June, and July, the medians of sediment grain size were significantly higher in the rip channel (202.7, 168.9, and 174.5mm, respectively) compared with its surrounding areas. In general, the mean sediment grain size was significantly higher in the rip channel (193.1mm) than the control area (176.3mm). In May, June, and July, the highest values of the mean grain size of sediments were related to the rip channel (226.9, 178.5, and 183.2mm, respectively).
Conclusion: The rip channel contains sediments with coarser grains than the surrounding area. The rip current leads the median and mean of sediment size distribution in the rip channel to move toward the larger sizes. Moreover, the skewness is a more sensitive factor to environmental changes of the channel and its surrounding area than the other sediment properties, emphasizing consideration in the studies.

Abstract

The key to the survival of a historical building is in its active mode and the spirit of dynamism in it. The dynamism of space is always an opportunity to create a stronger relationship between architecture and society, to organize sustainable urban development. Hence, in-between urban networks are highly important in reviving urban dynamism.
The purpose of this article is to recognize and analyze the areas affecting urban dynamism interacting with the concept of in-between space, with the solution of changing the land-use of sumptuous historical buildings based on neighborhood-based contemporization model and seeks to answer the question how intracity dynamism  is  defined as in-between space.
In order to achieve the objectives of the research, the process of analysis proceeds by selecting valuable historical buildings and how to change their land-use. This study aims to study the impact of changes in the land-use of selected buildings as an in-between space in urban dynamism by qualitative research of the indicators derived from the contemporization theory and has evaluated the effectiveness of metrics using the opinions of four groups of participants.
Several rehabilitated historical houses in Tehran were analyzed with TND approach and an emphasis on the neighborhood-based contemporization theory, then areas and strategies affecting urban dynamism resulting from land-use change were extracted, and finally, the most obvious effective characteristics in selected in-between buildings were introduced as urban communication network.
 

Volume 12, Issue 1 (Spring 2022)
Abstract

Aims: The strong relationship between place and society is evidence of the formation of sustainable social life in the urban space. The valuable houses, as part of modern heritage; and factories as part of the industrial heritage; are separated from their context. The main purpose of this research is to formulate a place-based development approach. According to the research hypothesis, there is a significant relationship between economic, structural, public and environmental factors.
Methods: In order to achieve the objectives of the research, the process of analysis has been organized with the method of logical reasoning and content-qualitative analysis of the texture of neighborhood centers. This study intends to study the effect of interface space on inner-city dynamism by qualitative studies of the indicators derived from the location-based development approach, using the opinions of participants to evaluate the effectiveness of effective metrics. Three neighborhoods have been studied, selected from among the historical and valuable neighborhoods of Hamedan.
Findings: Analysis of the interaction of elements left over from the past heritage of Hamedan, with emphasis on the theory of place-based development, showed that the reconnection of urban elements with each other is of special importance and is one of the most obvious effective features in intermediate spaces.
Conclusion: According to the place-based development approach, in the dimensions of the middle space, spatial arrangement and diversity of economic performance and socio-cultural infrastructure in the urban context of neighborhoods, have an increasing role in the vitality of neighborhoods and creating sustainable dynamism.

Abstract

Background: Harmaline exhibits a diverse array of pharmacological properties, including antimicrobial, antidiabetic, osteogenic, immunomodulatory, emmenagogue, and antitumor activities. The current study aimed to investigating the effect of harmaline on oxidative stress factors in lung epithelial cells exposed to elastase. Material and method: oxidative stress markers of lung epithelial cells were investigated in all cell groups including, control, H2O2, elastase and elastase plus harmaline (50, 100, 200 μm). lung epithelial cells (A549) were exposed to elastase with concentrations of 60 U/ml for 24 hours. In other groups, cells exposed to elastase were co-treated with three different doses of harmaline (50, 100 and 200 µm) for 24 hours at 37°C. Results: the results show a significant effect of harmaline's protective effect on cell viability, free radical production (ROS), malondialdehyde (MDA) and total antioxidant capacity (TAC). harmaline significantly increased the viability and TAC level in the cells exposed to elastase. Also, harmaline significantly decreased the percentage of free radicals and the MDA level in the cells exposed to elastase. Conclusion: The results obtained from this study showed a significant protective effect of harmaline on cell viability through increases in antioxidant defense system. Therefore, harmaline, can probably considered as a therapeutic strategy to prevent or treatment of lung diseases.
