Today, organizations need to develop "dynamic capabilities" to survive and succeed in a dynamic and changing environment. Dynamic capabilities enable the organization's ability to continuously renew resources and processes and adapt to environmental changes. Organizations are often interested in developing dynamic capabilities to respond to environmental changes. The main purpose of this paper is to explain the effects of dynamic capabilities (called DC), strategic foresight (called SF), and organizational learning (called OL) through a systematic review and bibliometric analysis that has been investigated. The analysis of "the possibility of integrating strategic foresight and organizational learning in the framework of dynamic capabilities" and deep and academic attention on "dynamic capabilities" is in this way. To strengthen their competitive power, organizations must address these changes by adjusting existing capabilities or acquiring new ones. Meanwhile, "strategic foresight" provides valuable information and insights about future developments or changes in the organization's business environment. After that, "organizational learning" integrates the information gained into the strategic planning process. Since organizations cannot use new information to make new decisions without learning, it seems very important and vital to include the concepts of "strategic foresight" and "organizational learning" in the framework of "dynamic capabilities". This report presents a new approach to linking these concepts and operationalizing the "dynamic capabilities" framework. One of the operational applications of dynamic capabilities is to improve performance and maintain the organization's stability.

Pain management is one of the important issues in dental treatments. Fear of pain can make the process of anesthesia injection before dental treatment difficult for both the dentist and the patient. The aim of this study was to compare the effect of Najo-Caine P® with topical Benzocaine in reducing the pain of needle insertion in palatal anesthesia in 9-12 year old children.

In a double-blind clinical trial, 23 children aged 9-12 years were selected via convenience sampling, who needed palatal anesthesia injection on both sides of the jaw, at the Dental Clinic affiliated with Mazandaran University of Medical Sciences, in 2022. The desired areas were air-dried for 5 seconds. Benzocaine was applied with a cotton swab on one side of the jaw, and in the next session with the same preparation on the other side of the jaw, Najo-Caine P® anesthesia (2.5% lidocaine cream and 2.5% prilocaine similar to EMLA) was applied by the injector for 2 minutes.

The Visual Analogue Scale (VAS) scores for Benzocaine and Najo-Caine P® were compared. The VAS score for Najo-Caine P® (3.52) was lower than that of Benzocaine (3.78), but, the difference was not statistically significant (P= 0.488).

Current study suggests that Najo-Caine P®, as a form of EMLA cream, can be used as an alternative to Benzocaine before palatal infiltrate injection to reduce palatal pain in children.

Sense of coherence (SOC) is an effective factor in health-related behaviors. Mothers' SOC can influence health and consequently the orodental health-related quality of life (OHRQoL) in their children. The purpose of this study was to investigate the relationship between mother's SOC and OHRQoL in 3 to 5-year-old children in Sari, Iran. A total of 190 children, along with their mothers, were selected out of those referring to the Touba Clinic in Sari. The SOC of mothers was assessed by Antonovsky's SOC-13 questionnaire, and the OHRQoL was evaluated using the Early Childhood Oral Health Impact Scale (ECOHIS). The dmft index was also used to determine the status of dental caries in children. A p-value of In this study, the mean scores of SOC, ECOHIS, and dmft index were 57.13±4.9, 13.8±0.4, and 7.4±1.33, respectively. The dmft index correlated negatively with SOC (r=-0.453, P≤0.001) and positively with ECOHIS (r=0.535, P≤0.001). In this regard, with increasing the mean dmft in children, ECOHIS scores also increased, but SOC scores in mothers decreased. The ECOHIS also had a negative correlation with SOC (r=-0.347, P≤0.001); in other words, with increasing mothers' SOC scores, the scores of quality of life also decreased. Mothers' SOC significantly affected dental caries and quality of life in their children. Therefore, with the increase in maternal SOC, OHRQoL can be improved.

Many economists, attribute the slowing growth of financial markets to ICT sector inefficiency; therefore the purpose of this study is to find out the effect of ICT development on Growth of capital markets in Iran, using empirical evidences of Tehran Stock Exchange for the time period of 2012 to 2014. For this purpose, a multivariate regression (OLS) model was used to analyze the impact of independent ICT variables such as number of online transactions users, amount of online trading volume, number of electronic published stock exchange notices for exchange users, total amount of ICT expenditure costs, the ratio of capital market active users to total number of stock exchange users and the ratio of online transactions to total number of transactions occurred during the period of study on dependent variable of capital markets growth rate in Tehran Stock Exchange. The results imply that there is a direct and meaningful relationship between ICT tools and equipments and capital markets growth rate in Tehran Stock Exchange which ultimately increases transactions and traders quantity at the end. But the results showed also a distinct result for using different methods of information economics transparency in the Stock Exchange market.

Dentistry is associated with high levels of stress as a result of financial issues, non-cooperative patients, stressful procedures, etc. Root canal therapy can potentially lead to high stress levels in dental students. Therefore, this study aimed to evaluate and compare factors causing stress during both the pre-clinic and clinical courses.
In this comparative-descriptive study, all the fifth- and sixth-year dental students in 2011-2012, a total of 125 students, were selected using the cluster sampling technique. In order to evaluate stress levels, a Likert scale questionnaire was designed. Data were analyzed with different descriptive methods using SPSS 19 (α = 0.05).
The maximum endodontics-related stress level was 58%. Improper behavior of professors in both the clinic (85%) and pre-clinic (92%) was the most important factor causing stress in students. insufficient lack of sufficient time for fulfilling the requirements was the most important factor causing stress in the pre-clinic, while the type and location of teeth were not as important.
Based on the results of the present study, professors’ poor behavior in the clinic and pre-clinic, cutting the power supply of the dental unit at a certain time and lack of sufficient time for finishing the job in the pre-clinic affected students’ stress levels.
