This study will seek to provide the best and most efficient ordering policies for different levels of the perishable food supply chain in order to maximize the overall profit of the chain, and minimize social and environmental damage. Our supply chain includes a four-level supply chain of suppliers, manufacturers, distributors and retailers. In addition to the components of perishable products, the dimensions of sustainable development have been fully investigated and taken into account in the entire chain. In this study, due to the main nature of perishable materials, the statistical population includes 9 dairy companies and 9 meat and protein companies, which in total 18 dairy, meat and protein companies in Fars province, Iran, were studied. Network Data Envelopment Analysis (DEA) was used to analyze the data and WinQsb was used to model and solve it. According to the results, the average efficiency of the supply chain of production and distribution of perishable products in the financial year studied by the research in the suppliers sector was equal to 0.9634. This average was equal to 0.9899 in the producers sector, 0.9903 in the distributors sector and 0.9707 in the retailers sector. Therefore, the average efficiency in the study shows that the most inefficiency problems of the studied companies are related to the supplier sector. Also, the overall average efficiency is equal to 0.9950.

Intelligence is an essential factor in supply chain. It prepares the ground for effective and timely communication and facilitates information sharing among supply chain components in both production and service sectors. Hence, the present study seeks to identify the components of services intelligent supply chain and categorize them as a comprehensive model by using the meta-synthesis approach. In this research, total of 437 articles in the field of services intelligent supply chain was identified and examined at first step. Articles were in the period of 1980 to 2022. Finally, after evaluation of articles, 53 articles remained. Then, based on the process of the meta-synthesis and the use of coding method, four main fields and a number of sub-fields were found for the services intelligent supply chain variable. Initial codes introduced in the software for conceptualization and categorization. The main fields of services intelligent supply chain included intelligence dimensions, intelligence conditions, intelligence strategies and intelligence consequences. Each of these main fields has a number of sub-fields. The result of the study shows that in order to implement the services intelligent supply chain, several dimensions and components are considered, concepts such as real-time online information flow, intelligent fund flow, intelligent services flow, process management and technology infrastructure play an important role. Suggestions are presented in accordance with the comprehensive model identified. Also, the conceptual model designed can be useful as a basis for future research in the direction of practical manual in the effective use of the services intelligent supply chain.

Iran, as one of the preventive (health) tourism regions and hubs of the world, has potential preventive and health capacities. On the other hand, health tourism brings three times more currency than other areas of tourism, so it is necessary to recognize the factors affecting the attraction of health tourists in different regions of Iran. According to 9 tourist regions in this article, which include region 1 (separately 5 land management regions, which are regions 2 (East Azerbaijan, West Azerbaijan, Ardabil and Kurdistan), region 5 (Fars, Bushehr, Kohgiluyeh and Boyer-Ahmad), region 8 (Yazd, Kerman, Sistan and Baluchestan and Hormozgan), region 1 (Gilan, Mazandaran, Golestan and Semnan) and region 3 (Hamedan, Kermanshah, Lorestan and Ilam) which in terms of health in areas with natural resources and suitable climate Comparative advantage and priority (regions 2, 1, 3, 5 and 8), preventive tourism demand (health) was estimated by the almost ideal demand method. Based on the opinion of 226 preventive health tourists in 5 land management areas, the sensitivity of foreign preventive tourism demand (health) to the effective factors and types of health tourism expenditures is measured. The results in all 5 preventive tourism areas indicate the sensitivity of foreign tourists to various macro factors such as inflation and exchange rates, the amount of personal income can be captured. In addition, the variables of relative prices (exchange rate), transportation and travel costs, medical facilities, standard accommodation, health tourism facilities, accommodation costs, health services prices, cooperation between tourism agencies and medical centers are all It affects the demand of tourists. Also, foreign tourists are highly sensitive to costs and preventive expenses in Iran and less sensitive to other expenses such as transportation and accommodation services and other expenses.

The present study investigated the effects of online training on Iraqi hotel management students’ speaking skills. A quantitative approach was adopted for the purpose of the study. Thirty-eight students participated in the study. Two groups were formed randomly; experimental and control. They took the PET test. Their scores from the PET test were used to check the homogeneity of the learners. Moreover, the learners’ pretest scores were considered as their speaking scores from the PET test. Based on the treatment, the experimental group received online speaking training through online applications such as Skype. On the other hand, the learners in the control group received their training through face-to-face interaction with the teacher.  After the treatment, the learners took the speaking test from the PET test. Their mean scores were calculated and compared to find any significant differences. The results showed that the learners’ speaking skills in the experimental group improved significantly in comparison to the control group. The results of the study also showed the importance of online training for improving the speaking skills of EFL and ESP students.
