Analyzing the Position of Rationality in the Strategic Plan for Tourism Development in Iran

One of the practical issues leading to the success or failure of tourism development plans is the type of rationality that dominates the country’s planning system in each era and the corresponding planning theory. This article has been compiled to analyze the position of rationality in planning as an epistemological framework in Iran’s strategic tourism development plan. This research’s conceptual framework of rationality is based on Alexander’s Rationality Model (2000) and the new approaches to tourism planning. The philosophical paradigm of the study is based on interpretive epistemology, and its methodology is based on qualitative research. Archival Studies and Thematic Analysis methods have been used for gathering and analyzing data in this research. The study’s statistical population for the content analysis comprises the qualitative texts of Iran’s strategic tourism development plan. The findings of this research indicate that, for the first time, coordinative rationality has become dominant in Iran’s strategic tourism development plan (Approved in 2020). The components of rationality were recognized, and the share of each type of rationality was outlined by analyzing 85 themes and thematic networks in the strategic plan in this research

Assessing the Prevalence of Ectopic Cerebellar Tonsils and Accompanying Symptoms in Individuals with Various Headaches

Objectives: Chiari malformation exhibits well-defined clinical signs, symptoms, and incidence rates in clinical studies. However, cerebellar tonsil ectopia presents with ambiguous symptoms and undetermined incidence rates in numerous studies. Our objective was to determine the incidence of cerebellar tonsil ectopia in individuals with headaches and identify additional clinical symptoms. This aims to improve diagnosis accuracy for clinicians and neurologists, leading to more effective treatment approaches. Methods: A cross-sectional study conducted in 2022 included 2305 participants aged 4–78 years presenting with headache. Chiari malformation was diagnosed using magnetic resonance imaging (MRI) scans, with a definition of cerebellar tonsil herniation extending beyond 5mm into the cervical canal. Results: The prevalence of Chiari malformation was 3.4%, with no significant gender difference (p = 0.72). There was a significant correlation between Chiari malformation and headache exacerbation due to the Valsalva maneuver (p < 0.001) and the presence of vertigo (p < 0.001). No significant association was found between Chiari malformation and accompanying symptoms such as nausea (p = 0.43), photophobia (p = 0.2), phonophobia (p = 0.52), and speech disorders (p = 0.45). Conclusion: These findings suggest a notable prevalence of Chiari malformation among headache patients and its association with specific headache characteristics, such as acute and occipital headaches, exacerbation by the Valsalva maneuver, and the co-occurrence of vertigo. These results underscore the need to consider Chiari malformation in the differential diagnosis of patients presenting with these specific headache features

Psychological Effects towards Humans Living in the Environment Made of Biological Concrete in Malaysia at 2015

In day-to-day life concrete become a compulsory material in the construction field as to make it a real concern among researchers for producing concrete with improved properties. Biological method is one of the new methods to improve concrete properties. Although, much research about biological concrete has been carried out, but till now nobody has not studied for the psychological effects of using a house or offices made up of biological concrete. The aim of this study is to investigate and find out the person's opinion about staying in a house or offices made up of biological concrete. In this study, a questionnaire containing eight questions was prepared and distributed among 21 persons in Malaysia University of Technology including students, academic and non-academic staffs among which few of them was an expert in the field of biological concrete and others did not have any knowledge about the bioconcrete. Finally, the results obtained from the questionnaires were analyzed. The results showed that 81% of participants in this study would like to stay in a house or office made up of biological concrete. However, 38% of participants believe that staying in a house or office made of biological concrete can cause health related problems. The current research paper can be considered significant for architects and civil engineers to have the insight to look into the psychological aspects of using biological concrete for various applications in the field of construction
