진홍우,오현정,이상준 한국EA학회 2023 정보기술아키텍처연구 Vol.20 No.4
ChatGPT와 같은 생성형 인공지능은 다양한 분야에서 이용되고 있다. 생성형 인공지능을 활용하 여 스마트 관광 서비스 품질을 향상시키는 연구가 필요한 시점이다. 본 논문에서는 ChatGPT가 스마트 관광 분야에 적용될 때, ChatGPT의 다양성, 설명성, 창의성, 불확실성과 같은 주요 특성이 사용자의 지 각된 유용성, 기대 일치 및 최종적인 서비스 만족도에 어떠한 영향을 미치는지 연구하였다. 데이터 수집 을 위해 ChatGPT의 핵심 특성 뿐만아니라, 스마트 관광의 중요 특성인 정보성, 접근성, 상호작용성, 개 인화에 관련된 문항을 설문조사하였다. SPSS 27.0을 사용하여 데이터 분석을 수행한 결과, 생성형 AI 기술, 특히 ChatGPT가 서비스 품질 향상에 중요한 영향을 미친다는 것을 실증하였다. 이러한 발견은 앞 으로 생성형 AI의 스마트 관광에서의 적용가능성에 대한 기초연구로서 가치가 있다. Generative artificial intelligence such as ChatGPT is used in various fields. It is time to conduct research on improving the quality of smart tourism services using generative artificial intelligence. In this paper, we study how key characteristics such as ChatGPT's diversity, explanations, creativity, and uncertainty affect on users' perceived usefulness, expectation confirmation, and service satisfaction when ChatGPT is applied to the smart tourism field. To collect data, we surveyed questions related to not only the core characteristics of ChatGPT but also the important characteristics of smart tourism: informativeness, accessibility, interactivity, and personalization. As a result of data analysis using SPSS 27.0, we demonstrated that generative AI technology, espe-cially ChatGPT, has a significant impact on improving service quality. These findings are valuable as basic research on the applicability of generative AI in smart tourism in the future.

2G HTS tapes are widely used for various electric machines. In addition, stacked or parallel connected HTS tapes are essentially used to raise transport current level for large capacity electric machines. Therefore, critical current characteristic of stacked tapes need to be studied. Recently developed 2G HTS tapes are fabricated with various defects doping so that tapes possess pinning center to improve the critical current characteristic. During this process, the critical current is determined minimum value in not perpendicular magnetic field but a specific magnetic field angle according to the reported research. However, the effects of magnetic field angle to critical current of multi-stacked 2G HTS tapes have not been examined. In this paper, field coil which is a race-track coil wound by using an HTS tape with iron-core was fabricated to apply angle adjustable magnetic field to the 2G HTS tape samples. We measured critical current of single and multi-stacked two tapes that have different characteristic depending on various magnetic field angle and magnitude in liquid nitrogen environment. Furthermore, results of single and multi-stacked tapes were compared and analyzed

This paper represents the detection method of voltage disturbance for high temperature superconducting (HTS) tape using electromagnetically coupled coils. In order to detect the voltage as the superconductor transits from the superconducting state to the normal conduction state, voltage taps are widely used to get the voltage signal. And voltage taps are connected to data acquisition device via signal wires. However this new suggested method can detect the superconducting transition voltage without signal wires between voltage taps and data acquisition device by using electromagnetically coupled coils. This system consists of two electromagnetically coupled coils, the first coil to detect and transmit the voltage of HTS tape and the second coil to pick up the transmitted voltage from the first coil. By using this new suggested method, we can build the ‘separated voltage-detection system’. HTS tape and first coil are located under liquid nitrogen vessel and the second coil is located under room temperature condition. In this paper, experiments are performed to verify the feasibility of the proposed method. As the result of the experiment, the separated voltage-detection system using electromagnetically coupled coils can successfully observe superconducting-normal transition of HTS tapes
