Persistent organic pollutants (POPs) usually originate from human activities and have been released into the environment for several decades. They are highly resistant to natural decomposition and can accumulate in an organism’s tissues and in all environmental components. Due to their unique characteristics, they have an ability to bio-magnify and bio-accumulate in animals, through the food chain and via inhalation, severely endangering the health of people. As reported, the exposure of humans to POPs causes various health problems such as cancers, diabetes, birth defects, endocrine disruption, cardiovascular diseases and dysfunctional immune and reproductive systems. The residents of South Korea are likely to face a high risk of diseases because of the existence of POPs in the environment. For instance, South Korea’s atmosphere has been reported as a hotspot for POP pollution. Besides, South Koreans’ high amount of seafood consumption is considered another source of POPs. Therefore, this article reviews the status of POP contamination in food and the health impact of POPs in South Korea. Based on the findings, the most-reported diseases were obesity and diabetes, which positively correlated to age, food habits, body index, and level of exposure to POPs. In addition, cancer and metabolic diseases are at an alarming level. Therefore, the public health impacts of POPs need continuous assessment in South Korea over the next decade.

Background: The COVID-19 pandemic-induced changes have threatened the psychological wellbeing of travelling. This review aims to appraise a range of perceived psychological variables used to realize how the pandemic has influenced tourist behavior. Methods: A systematic review was conducted to identify the mechanisms behind tourists' behavioral change during the pandemic. The papers were extracted from four databases: PubMed, SCOPUS, Web of Science, and EMBASE, published since 2020 to 2021. The results are summarized narratively due to the heterogeneity of the studies. Results: A total of 369 citations were identified through an electronic search of databases, of which nine publications met the inclusion criteria. The extracted information determines the significant factors contributing to the psychological changes of travelling behavior during the pandemic. Conclusion: The tourists' perception of COVID-19 has influenced the intentions and motivation in the tourism sector and has changed travel behavior. The mental health outcome of travelling has been replaced by globally recognized fear and anxiety. Yet, there are several motivators to travel during the pandemic. At the same time, the socio-demographic characteristics contribute to all the identified changes.

The stressful lifestyle of urban dwellers has increased the demand for green-based leisure activities; considering such growing demand, this paper investigated the potential mental health benefits of agritourism activities. The assessments were based on a questionnaire survey of two groups: visitors of agritourism sites around Seoul and a control group staying home (n = 200). In addition to measuring the participants’ well-being level and stress level, they were also asked to self-estimate their immediate mood after their activities of the day. The analysis was conducted with R version 4.1.0 to explore the potential relationships and interactions between the activity of the day, perceived psychological factors, and the immediate emotional outcomes. Findings reveal that visitors to the agritourism sites perceived considerable improvement in their immediate mood compared to the control group who stayed home. Results indicate a significant interaction between self-reported wellbeing and agritourism activities and a combined effect on improved mood. Therefore, agritourism can potentially be a resource for a positive mood boost and improved mental health. The suggested practical implications can be applied as strategies to evoke the feeling of more connection to the agritourism activities and raise awareness of potential mental health outcomes.

Background: The aim of this study was to provide a scientific method based on Geographical Information System (GIS) regarding all sustainable development measures to locate a proper landfill for disposal of hazardous wastes, especially industrial (radioactive) wastes. Methods: Seven effective factors for determining hazardous waste landfill were applied in Qom Province, central Iran. These criteria included water, slope, population centers, roads, fault, protected areas and geology. The Analysis Hierarchical Process (AHP) model based on pair comparison was used. First, the weight of each factor was determined by experts; afterwards each layer of maps entered to ARC GIS and with special weight multiplied together, finally the best suitable site was introduced. Results: The most suitable sites for burial were in northwest and west of Qom Province and eventually five zones were introduced as the sample sites. Conclusion: GIs and AHP model is introduced as the technical, useful and accelerator tool for disposal site selection. Furthermore it is determined that geological factor is the most effective layer for site selection. It is suggested that geological conditions should be considered primarily then other factors are taken into consideration.

Background: Medical tourism is a type of service sector in which there is direct interaction between healthcare practitioners and patient-customers, leading to several challenges due to cultural and social background differences. We aimed to investigate the determinants of delivering a culturally-oriented service in medical tourism sector. Methods: Adopting an exploratory qualitative approach, interviews were conducted through a semi-structured procedure with authorities across various medical sectors in South Korea in winter 2017. Participants were all involved in and aware of the medical tourism sector, both academically and clinically. The interview transcripts were coded through a systematic thematic analysis. Results: In order to focus on non-clinical service in medical tourism sector, and a system of cultural competence delivery, three main themes were identified: 1) The personal characteristics of doctors; 2) External supports to be provided by the associated organisations; and finally, 3) Skilfulness, which implies the culturallyoriented interaction with foreign patients. Conclusion: Several strategies are suggested to address the non-clinical challenges and conflicts in doctorpatient interaction in the sector of medical tourism. It is likely that providing a culturally-oriented service in this sector demands for a comprehensive planning, and several strategies for implementation in order to support and train a team of skilful doctors with non-clinical characteristics. These finding will likely have insights for those organisations searching to improve their performance in the medical tourism sector.

The experiences of South Korea in controlling the transmission of COVID-19 (coronavirus disease-2019) is valuable as a successful strategic plan. However, this research aimed to investigate the effective factors in this process from different perspectives. Based on an analysis of the available information and statistics published by the government, World Health Organization, and local organizations, this research was searching for not only the effective approaches in controlling the transmission but also the effective factors that roots in Korean cultural background and lifestyle. The critical points in controlling the virus transmission in Korea have been to respond promptly, besides of designing an active system of tracing, and early detection. The supply chain management prevented any shortage on the required products. Advanced technology guaranteed the safety of the medical facilities. However, another efficient factor was the Korean social and cultural background, besides the national solidarity. The findings highlight that the mechanisms that help South Korea fight in controlling the transmissions of the pandemic were in line with the World Health Organization’s recommendation. However, South Korea gained advantages from other factors that have roots in their social interactions, cultural background, and the well-established and advanced IT systems that enabled the government to manage the outbreak of COVID-19.
