Recently, the travel and lodging industries have been suffering from the spread of COVID-19. But Airbnb recovered its profits with a differentiated strategy. This study identified the characteristics of Airbnb and examined their effects on customer's revisit intention in the Airbnb context. Perceived value, trust about Airbnb, and social norms were considered as the key factors of revisit intention. In addition, the effects of relative attractiveness, brand identification, and enjoyment on perceived value and trust about Airbnb were examined. The proposed research model was tested based on 285 consumers who had Airbnb experience more than twice. The analysis results showed that relative attractiveness, brand identification, and enjoyment had a significant influence on perceived value and trust. Perceived value had a significant influence on revisit intention. However, trust about Airbnb and social norms did not significantly affect revisit intention. Moreover, ths analysis results found no significant moderating effect of share of wallet. Based on the results of this study, Airbnb would establish effective marketing and operation strategies by understanding the formation mechanism of consumer's revisit intention toward Airbnb.

Purpose: Nowadays, the risk assessment system is widely used in many industrial and public areas to reduce the possible risks. The system is used to determine the priorities of the government quality assurance works in Defense Agency for Technology and Quality. However, as the risk assessment system is used for other purposes, there are some items that need improvement, and in this study, we propose improvement plans by benchmarking the risk assessment systems of other institutions. Methods: In this paper, first, the procedures of risk assessment system used in many industrial sites were reviewed, and how each institution specialized and applied the system. Afterwards, by benchmarking various risk assessment systems, an improvement plan on how to operate the risk assessment system in the case of government quality assurance for centrally procured military supplies was presented, and practical application cases were presented to prove the usefulness of the improvement plan. Results: The proposed risk assessment system differs from the existing system in five major aspects. First, inputs, outputs, and key performance indicators were specified from the systematic point of view. Second, risk analysis was analyzed in four dimensions: probability of occurrence, impact, detection difficulty. Third, risk mitigation measures were classified, control, transfer, and sharing. Fourth, the risk mitigation measures were realized through document verification, product verification, process verification, and quality system evaluation. Finally, risk mitigation measures were implemented and the effectiveness of the risk mitigation measures was evaluated through effectiveness evaluation. Conclusions: In order for the risk assessment procedure proposed in this study to be applied to actual work, it is necessary to obtain the consent of the person involved in the work due to the increased time for risk identification and preparation of the government quality assurance log, and a change in the information system that performs the actual work is required. Therefore, the authors of this study plan to actively perform internal seminar presentations and work improvement suggestions to apply these research outputs to actual work.

AESA radar is able to instantaneously and adaptively position and control the beam, and this enables to have interleaved mode in modern airborne AESA radar which can maximize situational awareness capability. Interleaved mode provides two or more modes simultaneously, such as Air to Air mode and Sea Surface mode by time sharing technique. In this interleaved mode, performance degradation is inevitable, compared with single mode operation, and effective resource allocation is the key component for the success of interleaved mode. In this paper, we identified performance evaluation items for each mode to analyze interleaved mode performance and proposed effective resource allocation methodology to achieve graceful performance degradation of each mode, focusing on detection range. We also proposed beam scheduling techniques for interleaved mode.

The purpose of this study is to establish a linkage between local forest human resources policies and the analysis of forest resource conditions in Gyeongsangbuk-do. In particular, the study aims to gather insights from students enrolled local formal education institutions through a demand survey and their opinions. These findings would serve as basic data for the formulation of medium- and long-term policies. According to the results of the analysis, all surveyed groups expressed a desire to pursue careers, entrepreneurship, or further school education based on their forestry majors. Among, the most important needs identified for local human resources, receiving training related to field practice and access to information emerged as paramount. In addition, it was observed that educational programs were conducted on weekends and during school vacations, with integration into the school curriculum to ensure participants not only benefit from self-development but also receive administrative support. A notable observation in the survey results was the absence of a network among forest professionals, signifying a key weakness within the forest sector in Gyeongsangbuk-do. The results of this study hold significant value in terms of analyzing and sharing the educational preferences of forest human resources in Gyeongsangbuk-do, thereby serving as basic research data for proposing policies. In the future, by expanding the scope to include case studies and forest human resource preference analyses through cooperation with other local governments and institutions, the research can contribute to the establishment of national-level policies for forest human resources on a broader scale.

Objectives This review was conducted to evaluate the therapeutic effects of manual acupuncture (MA) for shoulder impingement syndrome (SIS). Methods We searched 12 electronic databases (DBpia, Korean studies Information Service System [KISS], Oriental Medicine Advanced Searching Integrated System [OASIS], Research Information Sharing Service [RISS], China National Knowledge Infrastructure [CNKI], CINAHL, Clinical Key, Cochrane Library, Embase, JAMA, PubMed, Web of Science) to find randomized-controlled clinical trials (RCTs) investigating therapeutic effects of MA for treating SIS. Shoulder Pain and Disability Index scores and numeric pain rating scale or visual analogue scale were analyzed as the main evaluation criteria. Results Among 181 studies, 169 were screened and only 12 RCTs were eligible in our review. Finally, 11 RCTs could be statistically analyzed. MA was more effective than sham treatment and physical therapy in terms of reducing pain (p=0.003, p=0.0007 each). Electroacupuncture (EA) showed more significant effect than physical therapy (PT) for improving shoulder pain (p<0.00001) and shoulder functionality (p<0.00001). Conclusions These results suggest that MA and EA could be superior option for treating SIS than sham treatment or PT. However this review has its limitations due to the small sample size and lack of well-designed RCTs that were included in the study. Further well-designed RCTs are necessary to provide high-level evidence.

The purpose of this study is to analyze empirically analyze how the characteristics of participants in educational and social learning forums and the quality of events influence expectations and satisfaction of forums. The study also aims to provide strategic implications for forum organizers and give them suggestions on how to set up target audience, manage forum contents, speakers, and services, improve attendee satisfaction, and ultimately maximize overall outcomes. As exchanges among individuals, enterprises, and organizations, as well as countries are growing rapidly, the convention industry has become a key player in the market. Conventions have also become a venue for people to discuss a specific agenda or topic, exchange information and learn knowledge and insights. Especially, the forum - as part of the convention industry - plays a vital role providing educational and social learning opportunities as scholars and expertise come together to share their knowledge and experience through a variety of discussions. With its role, many of forums are taking place in recent years; however, there have been few empirical studies upon the forum itself. Also, there have been few attempts to research how the quality of forums affect participants' satisfaction along with their characteristics and how much of practical knowledge is provided throughout the events. This study is meaningful in that it is the first practical study that takes a deep understanding of the forum and sees how the quality of the forums influences participants' satisfaction and whether the characteristics of participants have a moderating effect in increasing the level of satisfaction. Forum organizers could also take a strategic approach as their major concerns are to increase the number of participants and raise degree of satisfaction by providing significant information. There are four key elements that determine success or failure of a social learning forum. The four elements are contents, speakers, services, and participants. Content plays an important role in providing rich information and knowledge for participants. Speakers are the main knowledge providers who contribute to the forum's social learning role. Also, the services provided by forum organizers such as simultaneous interpretation services, program brochures, lunch and refreshments, and the overall design of event hall can also influence the level of participants' satisfaction. Lastly, the participants and their characteristics are important since they are the ones who receive knowledge from the providers. The results of this study show that the quality of forum (content, speaker, and services) has a decisive effect on the participants' satisfaction and there are some differences in expectation among the participants in the forum. Also, some groups of participants were more likely to be stimulated by the quality of forum when determining their satisfaction. The study is modeled after MBN Y Forum 2016 and its participants' characteristics. The forum is one of the most representative social learning forums of South Korea and its audiences are mostly young people. It has analyzed how the participants' characteristics influence their satisfaction by grouping them into ${\Delta}participants$ who have invited for free and those who paid for the entrance fee, ${\Delta}first-time$ participants and returning participants, ${\Delta}voluntary$ and involuntary participants, ${\Delta}participants$ who registered through web and those who did through mobile, and ${\Delta}participants$ who registered during pre-sale opens and those who registered during general opens.

Universities have recognized e-Learning Systems as the critical IT resources which contribute to improving the competitiveness of the universities as well as the quality of the traditional class-based lectures. Instructors deliver the main contents in the class. Other supplementary activities like online discussions, sharing of teaching-learning materials, submission of homeworks, communication among the learners and between the instructors and the learners, and so on can be efficiently facilitated using e-Learning Systems. In other words, e-Learning Systems enable a blended learning combined class-based lectures and e-learning in a variety of ways. Nonetheless, compared to the level of implementation of e-Learning Systems, the usage of both the instructors and the learners is not high. Accordingly, this study examines the determinants to affect on the usage of e-Learning Systems from the learners perspective. To draw the key determinants, we review the IS literatures related to adoption or use of the IS like Media Richness Theory (MRT), Technology Acceptance Model (TAM), Social Influence Model (SIM), and Self-efficacy Model. The variables are drawn out to be expected on the usage of e-Learning like Media Richness, Ease of Use from MRT, TAM and Instructor's Influence, Co-learner's Influence from SIM, and Self-efficacy. To test our model and hypotheses, we have collected data in the class-based lectures using e-Learning System complementary. The results of the test with 192 data are as follows: Firstly, it shows that the Instructor's Influence and the Media Richness are the influential determinants to affect on the Perception of Usefulness of e-Learning Systems. Additionally, the Co-learner's Influence and Ease of Use in order is significant to the Perception of Usefulness. Secondly, as to the degree of use of the e-Learning Systems, the Co-leaner's Influence, the Media Richness, and the Ease of Use are, in that order, the significant determinants. The Perception of Usefulness, also, founded a key factor on increasing the use of e-Learning Systems. On the other hand, the Instructor's Influence is not significant to the use of e-Learning Systems. Finally, it has been found that Self-efficacy is significant to the Perception of Media Richness, Ease of Use, but not significant to the Perception of Usefulness.

The purpose of this study is to promote the activation of creative problem - solving education in Korea through the case of countries leading education for creative problem solving in order to overcome the limitation of creative problem solving education in Korea. Based on 5 success factors by our cases of United States, Singapore, and Dublin City University in Ireland, we focused on the cases and extracted five key characteristics of creative problem solving education. The university should be able to provide various information gathering and theoretical knowledge for problem definition as well as continuing guidance and mentoring, rather than one-time teaching, in the form of teaching-student cooperative learning paradigm. Second, the class should be a team - based learning team which is a key factor in overseas universities' policy, so as to be able to identify differentiated, new ideas and creative problem solving methods based on knowledge and experience sharing. The creative problem solving method derived from education could be able to collect, organize, and apply to the field continuously and comprehensively about the learning process of the individual. Evaluation of curriculum should be based on characteristics of school and characteristics of students. The results of creative problem-solving education should be evaluated in order to continuously develop and create value in addition to the outcomes of the class. Therefore, it is necessary to develop an evaluation process for each university. The university should try to make creative problem solving education create value through specialization of university. Based on this, we propose a creative problem solving education framework.
