With changes in information technology (IT), many innovative IT-based services, such as AirBnB, have become popular. Switching behavior toward new and innovative services become a major issue for managers who want to attract many customers. In response, many researchers have investigated why customers switch service providers. However, little research has been conducted on the processes of switching behavior for a hedonic service. To fill this research gap, this study aimed to identify the stages of switching behavior based on transtheoretical model. Furthermore, the factors affecting the service switching behavior in stages were identified on the basis of service provider switching model. This study also hypothesized the customer's switching behavior in accommodation sharing economy service and analyzed it empirically. Results showed that the factors affecting switching behavior differ across five stages. The present results can provide a basis to prevent switching behavior and reduce churn by analyzing the difference in switching behavior among stages. This study also helps managers who want to improve organizational performance by enhancing customer retention capability.

In order to secure sustainable competitiveness of startups, business model innovation is an important task to achieve competitive advantage by transforming the various elements that make up the business model. This study conducted a multi-case analysis study on leading smart farm companies around the world using an analysis framework based on business model theory. Through this, we sought to identify business model types and their constituent elements. For this, 19 companies were selected from the list of top 10 investment startups of the year for the past three years published by Agfunder, a global investment research company specializing in AgTech. Then data collection and analysis of the company cases were conducted according to the case study protocol. As a result of the study, the business model types were analyzed into four types: large-scale centralized production model, medium-to-large local distributed production model, small-scale hyperlocal modular FaaS model, and small-scale hyperlocal turnkey solution supply model. A comparative analysis was conducted on five business model components for each type, and strategic implications were derived through this. This study is expected to contribute to improving the competitiveness of domestic smart farm startups and diversifying their strategies by identifying the business models of overseas leading companies in the smart farm field using an academic analysis framework.

The National Library for the Disabled was upgraded to a primary affiliated organization of the Ministry of Culture, Sports and Tourism on June 4, 2020, in accordance with Article 24 (1) of the Library Act (Law No. 16685). The National Library for the Disabled is currently preparing to build an independent library building. Now that the National Library for the Disabled has secured its independent legal status, it must become a specialized national library by comprehensively collecting not only alternative materials for the disabled, but also domestic and foreign materials useful to researchers related to the disabled. Accordingly, the purpose of this study is to conduct basic research for comprehensive and strategic collection of library materials for people with disabilities, which is an essential part of the statutory work of the National Library for the Disabled. To this end, the concept and category of library materials for the disabled that are expected to be useful for satisfying the intellectual needs of the disabled and for education and research related to the disabled were established targeting knowledge information resources produced and distributed domestically and internationally. Next, based on the current collection development policy of the National Library for the Disabled, an implementation strategy and mid to long term roadmap for comprehensively collecting library materials were presented.

In particular, as the current educational institutions are becoming more competitive, universities need to make efforts to survive the fierce competition by improving their service qualities. In this situation, this study was conducted to confirm the effect of international students' evaluation of university service quality on university loyalty through university satisfaction and service engagements, And several implications can be suggested as follows. First, the dimensions of university service quality were identified as important factors that had a great influence on the university satisfaction of international students. Among the service quality dimensions, support services related to international students were found to be the most important variable in university satisfaction. The school's efforts to solve the inconvenience of international students and the grievances of students who feel difficulties that their own students do not feel are considered a very important factor in the satisfaction of international students. Second, it was found that international students' class engagement or friendship engagement can be increased through satisfaction with the school, and eventually, the increased engagements affect university loyalty. In particular, it has been verified that for international students, the loyalty of the school can be increased by establishing friendships with students from various countries and participating in various school programs. Finally, according to the purposes of studying abroad, the difference was confirmed between the groups studying for academic development and better employment and the group employed for overseas experience and immigration.

ISNI is a relay identifier that can integrate universal archival data and has the advantage of being flexibly applied to various fields compared to ORCID, which is limited to academic researchers, but in Korea, it is overwhelmingly issued to researchers and educators, and its purpose is gradually fading. In particular, overseas, ISNI issuance is active with the active participation of the publishing industry, but in Korea, there is no issuance through the publishing industry. This study was designed to expand the issuance of ISNIs to various fields including the Korean publishing industry. In order to achieve the research objectives, in-depth interviews were conducted with representatives of the existing ISNI-KOREA consortium organizations and potential consortium expansion organizations such as the publishing industry. As a result of the interviews, four policy implications were drawn as a way to revitalize ISNI: reorganizing its own system, strengthening governance, promotion and education, and system linkage. To address these policy implications, we proposed a mid- to long-term development plan centered on four policy goals and 12 key tasks. This study is expected to help the National Library of Korea, which operates the ISNI-KOREA consortium, develop policies related to ISNI activation.

The future military combat environment is rapidly expanding the role and importance of artificial intelligence (AI) in defense, aligning with the current trends of declining military populations and evolving dynamics. Particularly, in the civilian sector, AI development has surged into new domains based on foundation models, such as OpenAI's Chat-GPT, categorized as Super-Giant AI or Hyperscale AI. The U.S. Department of Defense has organized Task Force Lima under the Chief Digital and AI Office (CDAO) to conduct research on the application of Large Language Models (LLM) and generative AI. Advanced military nations like China and Israel are also actively researching the integration of Super-Giant AI into their military capabilities. Consequently, there is a growing need for research within our military regarding the potential applications and fields of application for Super-Giant AI in weapon systems. In this paper, we compare the characteristics and pros and cons of specialized AI and Super-Giant AI (Foundation Models) and explore new application areas for Super-Giant AI in weapon systems. Anticipating future application areas and potential challenges, this research aims to provide insights into effectively integrating Super-Giant Artificial Intelligence into defense operations. It is expected to contribute to the development of military capabilities, policy formulation, and international security strategies in the era of advanced artificial intelligence.

The Lombard effect is an involuntary response to speakers' experiences in the presence of noise during voice communication. This study aimed to investigate the Lombard effect by comparing the acoustic features of children and adults under different listening conditions. Twelve male children (5-9 years old) and 12 young adult men (24-35 years old) were recruited to produce speech under three different listening conditions (quiet, noise-55 dB, noise-70 dB). Acoustic analyses were then carried out to characterize their acoustic features, such as F0, intensity, duration, and vowel space area, under the three listening conditions. A Lombard effect was observed in the intensity and duration for children and adults who participated in this study under adverse listening conditions. However, we did not observe a Lombard effect in the F0 and vowel space areas of either group. These findings suggest that children can adjust their speech production in challenging listening conditions as much as adults.

Until Montreal Convention was established in 1999, the Warsaw System is undoubtedly accepted private international air law treaty and has played major role on the carrier's liability in international aviation transport industry. But the whole Warsaw System, though it was revised many times to meet the rapid developments of the aviation transport industry, is so complicated, tangled and outdated. This thesis, therefore, aim to introduce the Montreal Convention by interpreting it as a new legal instrument on the air carrier's liability, specially on the passenger's, and analyzing all the issues relating to it. The Montreal Convention markedly changed the rules governing international carriage by air. The Montreal Convention has modernized and consolidated the old Warsaw System of international instruments of private international air law into one legal instrument. One of the most significant features of the Montreal Convention is that it sifted its priority to the protection of the interest of the consumers from the protection of the carrier which originally the Warsaw Convention intended to protect the fledgling international air transport business. Two major features of the Montreal Convention adopts are the Two-tier Liability System and the Fifth Jurisdiction. In case of death or bodily injury to passengers, the Montreal Convention introduces a two-tier liability system. The first tier includes strict liability up to 100,000SDR, irrespective of carriers' fault. The second tier is based on presumption of fault of carrier and has no limit of liability. Regarding Jurisdiction, the Montreal Convention expands upon the four jurisdiction in which the carrier could be sued by adding a fifth jurisdiction, i.e., a passenger can bring suit in a country in which he or she has their permanent and principal residence and in which the carrier provides a services for the carriage of passengers by either its own aircraft or through a commercial agreement. Other features are introducing the advance payment, electronic ticketing, compulsory insurance and regulation on the contracting and actual carrier etc. As we see some major features of the Montreal Convention, the Convention heralds the single biggest change in the international aviation liability and there can be no doubt it will prevail the international aviation transport world in the future. Our government signed this Convention on 20th Sep. 2007 and it came into effect on 29th Dec. 2007 domestically. Thus, it was recognized that domestic carriers can adequately and independently manage the change of risks of liability. I, therefore, would like to suggest our country's aviation industry including newly-born low cost carrier prepare some countermeasures domestically that are necessary to the enforcement of the Convention.

Nowadays, in the European countries, landscape is spoken of its importance as often as environment, by those who are engaged in such fields as politics, administration, research and civil society. In Korea, while recognizing such an international trend, academics and administrators have made a series of efforts to reflect landscape concept on a variety of policies. However, it is recognized that the effects of these policies have not been satisfactory. Under these circumstances, this paper aims to examine the complex values and multiple meanings in the landscape, which have been discussed by landscape experts in the European countries. Then, it aims to the explore the future direction of policy and research on the landscape to be pursued in Korea, where there is relatively less interest in the issues of landscape. It is argued that landscape should be approached and understood from a holistic perspective, because it is a very complex concept with multiple meanings that have been coined differently depending on the situation. All the academic fields, involved in the landscape research, should try in co-operation to develop the comprehensive approach rather than the inter- and multi-disciplinary approach to the landscape study. In Korea, moreover, it is also necessary in the legislation to recognize the fact that degradation and retreat in the quality of landscape would make a negative effect on the quality of human daily life. Natural and cultural heritages contained in the rural landscape are also now in danger of disappearing. These heritages, therefore, should become an important subject for research and policy on landscape before the countryside is completely evacuated after the aging population die out. To make this happen, it is very urgent that evaluation and classification of landscape character should be undertaken from the holistic perspective, which is equipped with a methodology overcoming as well as encompassing the boundaries of academic fields. It is also equally very urgent that education on landscape should be provided to the politicians, citizens and students as well as the officials dealing with landscape matters. Finally, government should strive to make the landscape concept penetrate deeply as well as widely into the spatial planning and legislation process while designing and implementing a comprehensive landscape policy at the national level.
