During the pandemic, social distancing continued for a long period of time, and as a result, this situation raised the possibility of the online space as a place for serious social relationships. In particular, metaverse platforms are adding to the reality of virtual space by expanding their functions so that users can provide various online events and have a variety of new experiences. This study attempted to examine the social relationship between reality and the metaverse according to social inclinations and behavior patterns. As a result of this study, the group with a high sense of inferiority in their usual relationship and the group with low satisfaction with their usual social interaction felt high discomfort at a similar level in both real and metaverse relationships. The group with the opposite inclination felt more uncomfortable in the metaverse relationship than in reality. In addition, whether the behavior patterns in the metaverse and in reality were different or same did not significantly affect the difference in attidudes between the metaverse and reality. In the case of group with different behavior patterns, however, if they were satisfied with how they look in the metaverse, their intimacy with social relationships was also high. This results implicate that we need to make an special effort for the development of social relationships in the metaverse era.

This study aims to understand a gamer participatory mechanism by comparing Gamer Participation 1.0(Bartz Liberation War) and Gamer Participation 2.0(Truck Demonstration). The process of gamers' political participation is analyzed by applying the communication-mediated O-S-O-R model with the case of gamers' truck protests caused by probability items' issue. This study found out that changes in the social, technological, and discursive layers that constitute the gamer's communication ecology led to diversification of communication channels and changes in the perception of games. Gamers utilized the technological layer of the media environment that presupposes immediate mutual communication, expressed opinions on issues in the mobilization process, and shared the necessity of participation to derive collective mobilization. Through communication, gamers were able to participate in socio-political issues with high participation thresholds. This study is significant in that it discussed the gamers' democratic citizenship and role as issue publics. The study suggests that the need for theoretical and methodological expansion to analyze various participatory cases.

Recently, the number of natural and environmental disasters is rapidly increasing due to extreme weather caused by climate change, and the scale of economic losses and damage to human life is increasing accordingly. In addition, with urbanization and industrialization, the characteristics and scale of extreme weather appearance are becoming more complex and large in different ways from the past, and need for remote sensing and artificial intelligence technology for responding and managing global environmental disasters. This special issue investigates environmental disaster observation and management research using remote sensing and artificial intelligence technology, and introduces the results of disaster-related studies such as drought, flood, air pollution, and marine pollution, etc. in South Korea performed by the i-SEED (School of Integrated Science for Sustainable Earth and Environmental Disaster at Pukyong National University). In this special issue, we expect that the results can contribute to the development of monitoring and management technologies that may prevent environmental disasters and reduce damage in advance.

The length, the frequency, and the methods of surveillance for intraductal papillary mucinous neoplasm (IPMN) of the pancreas are still debating. According to the recent guidelines, IPMN is stratified into "high-risk stigmata" or absolute indication and "worrisome features" or relative indication as a guide in managing these patients, either those with resection of the lesion or those under surveillance. The risk of malignant transformation was quite low for branch duct-IPMNs without worrisome features or high risk stigmata. However, because the incidence rate of pancreatic cancer in these patients increase linearly with time, continued long-term surveillance is therefore important for patients with low-risk, as well as higher-risk, IPMN. Considering the high prevalence of malignancy, main duct-IPMN should be treated by surgical resection. Among patients with these type IPMNs, segmental dilatation of the main pancreatic duct without any mural nodules and larger than 10 mm of main pancreatic duct might not be immediately resected and need very careful examination and observation. The risk related to a major pancreatic resection must balance the risk of surveillance in patients with IPMN of the pancreas who have co-morbidity and are elderly.

This study proposes the design and implementation of a low-cost emergency ventilator which can be helpful during the COVID-19 pandemic where the supply of automatic ventilators is not smooth compared with the urgent demand worldwide. Easy implementation and lower price were made possible by using AMBU-bag and off-the-shelf embedded micro-controller board. Moreover, while 3D printing is used by companies and experts around the world to build prototype hardware, materials which are readily available from surrounding environments so that people in countries where it is difficult to access many advanced technologies could manufacture the system. The design features AMBU-bag automation, not use 3D printing, and it can contrl speed. By allowing speed control, ventilation can be performed according to the conditions of the patient being used. A complementary point in the study is that it is difficult to fix the start point of the wiper motor used first. A method for complementing this is a method for replacing the brush DC motor with a position feedback function. Secondly, the AMBU-bag may wear out in the long-term process of compressing the AMBU-bag because the arm and the fixing frame are made of wood. To complement this, the part of fixing frame and arm parts that the AMBU-bag touches need to be wrapped in a material such as silicon to minimize friction.

For the successful execution of an ODA project, it is necessary to know what areas are weak and necessary to the country of demand exactly. The health sector is also a top priority in most of developing countries. This study was carried out to introduce non-communicable disease (NCD) in Fiji for ODA projects planning. The major causes of death in Fiji in 2016 are diabetes, ischemic heart disease, cerebrovascular disease, chronic kidney disease, lower respiratory infect, asthma in ranking. The major causes of death in Korea in same year are cancer, ischemic heart diseases, cerebrovascular diseases, pneumonia, suicide, diabetes in the order of ranking. The chronic disease as non-communicable disease (NCD) has been increasing continuously due to changes in lifestyle and consumption patterns and population aging in prevalence rate. This global trend is also apparent in Fiji and Korea, reflected in increasing mortality and personal costs for the treatment and management of NCD. The need for a sustained comprehensive treatment tailored for individual patients has suggested from many studies and the development of a systematic program to manage NCD patients to provide such care have been recommended. The Fiji government developed Non-communicable Diseases Strategic Plan 2015-2019 and has tried to reduce the prevalence rate of non-communicable diseases by factors. The WHO global action plan guiding national-level NCD policies requires an NCD prevention and control model at the community level, presenting strategic goals and detailed options for the introduction and application of the approach to communities. It is necessary to develop an NCD prevention and control model, consisting of a strategy of community intervention, education for students and NCD patients, and the legal enactment of NCD that adequately meets the needs of community members.

The purpose of this study is to explore the inner perceptions and dilemmas of young people about the church. To achieve the purpose of the study, this study sampled the research subjects, and conducted in-depth interviews and FGI. The sample in this study was 21 young adults who met the study criteria. Some of these people are not currently attending church or have thought of moving to another church. In this study, research was conducted based on the analysis procedure of Riessman (1993). Focusing on the procedures of 'telling,' 'recording,' and 'analyzing,' the experience and life situation of the study participants are to be grasped. Through this process, we analyzed the situation and context of why young people leave the church. It consisted of 5 areas and 15 sub-themes. Based on the research results, it was found that young adults need a church and are looking for a church. The church is a mystical space, but from an pedagogical point of view, the church is a space for teaching and learning faith. As experts in theology and education, the minister must create a space so that the church can become a space of transcendence, a space of intimacy, a space of understanding, a space of change, a space of service, and a space of reflection.

The purpose of this study is to present an approach to the "Digital Health Passport" (DHP), which will be the most important in the change of the travel industry among the sudden environmental changes brought about by COVID-19. To this end, this study reviewed a variety of empirical literature on DHP, and proposed a framework for DHP based on literature review. The framework is composed of travel intention, health information provision intention, and new technology acceptance/adoption of tourists. First, in terms of travel intention, providing information to DHP should not undermine the travel intention of the travelers. It should be possible to facilitate the travelers' enjoyment by using the information provided by the traveler. In addition, there is a need to assure that the data provided by travelers is managed in a reliable way. Second, it is necessary to understand why the travelers want to provide additional personal information (information disclosure), rather than seeing healthcare information only in terms of mandatory information provision. Finally, from the perspective of new technology, it is necessary to understand the intention of travelers to use/adopt DHP. The key implication of this work is that it proposed a DHP framework for realizing the travel bubble to predict and respond to foreign travelers' behaviors.

In the 21st century, a number of storm and flood disasters caused by rapidly changing climate change is increasing, and the number of flood accidents at construction sites is also increasing. However, no specific reduction measures have been presented and thereby safety management to prevent flood accident need to be improved. Therefore, in this study, the inundation pattern by downpour at the excavation site was interpreted and the inundation risk quantification method was used to classify the risk magnitude. Finally, using the fish-bone diagram, we derived the major reasons of inundation accident at construction site systematically. The simulation results showed that the inundation depths of small-scale excavation sites and excavation sites exceeded 3 m due to the fluid flowing through the excavation surface. In addition, depending on the excavation site, a high velocity temporarily observed and decreased due to the storage effect, or high velocity surpassing 10 m/s continued. Since this type of flooding can pose a risk to most or all workers, if proper management measures are insufficient, fatal damage to life and property could occur. Consideration of the roots of these disasters is judged to be helpful in understanding the causes of inundation accidents that result in casualties and presenting accident reduction measures.
