European efforts to design superconducting conductors for a future tokamak have involved Nb₃Sn cable-in-conduit conductor (CICC). Nb₃Sn coils which undergo heat treatment to activate the Nb₃Sn material are mostly produced through the wind-then-react route. However, some Nb₃Sn coils have been proposed with CICCs of the react-then-wind route. The latter CICCs are physically constrained due to handling limitations which if not adhered to will result in irrecoverable damage to the Nb₃Sn cable inside, nullifying any performance advantage. A group at the Swiss Plasma Center has proposed such CICC designs, constructing samples and testing them for performance. The characteristics and performance of these react & wind (R&W) CICCs are compared with the more common wind & react (W&R) CICCs, and it is found that the R&W designs show more extreme characteristics than typical W&R Nb₃Sn CICCs for some parameters that are known to influence CICC performance. Where the R&W CICCs extend the range of those parameters, they also continue trends formed by the W&R CICCs with the parameters. The main observation, however, is that although the current sharing temperature performances of the R&W samples are above the average of the W&R samples they were compared to, they are not the highest. A similar observation applies to a cost comparison of the superconducting material where the R&W CICCs are found to be relatively cheap but not the cheapest. Given these results, clear practical advantages to the R&W CICC design is not evident.

모바일 시장에서는 앱을 빠르게 개발하여 시장의 평가를 받는 것이 중요하다. 하지만 소규모 회사에서 단편화된 모바일 환경에 대응하여 제품을 신속하게 개발하고 배포하는 것은 어려운 일이다. 본 연구에서는 높은 수준의 기능과 성능을 요구하는 모바일 앱 개발 시에 크로스 플랫폼 솔루션인 React Native와 Unity3D를 동시에 활용하여 제작한 통합 개발 결과물이 요구 조건을 충족할 수 있음을 보인다. 또한 크로스 플랫폼을 통합한 개발 방식이 모바일 앱의 개발기간을 단축하고 개발 비용을 절감할 수 있음도 보여준다.

We develop a smart tourism information system that provides smart tourism services to free independent tourists (FITs) through various content distribution channels such as mobile apps, Instagram, YouTube, and chatbots. The smart tourism information system provides location and storytelling-based tourism information, accommodation, restaurant information, and recommended travel products so that tourists can create a travel itinerary based on personalized situation awareness. The smart tourism information system also provides smart tourism services using commercial maps, navigation, and weather forecast APIs from the Korea Meteorological Administration to provide smart tour guide services to tourists who travel according to the travel itinerary. In this paper, we develop the React Native app that provides smart tourism services provided by the smart tourism information system. The smart tourism React Native app has implemented two methods: a method that directly connects to the smart tourism information system, and a method that provides services by interworking through the GraphQL Query Language developed by META (Facebook). The smart tourism React Native app implements OSMU (One Source Multi-use) by providing tourism information from mobile apps, photos from Instagram, and drone videos from YouTube as an integrated UI.

The global surge in depression and anxiety, intensified by challenges such as cost and stigma, emphasizes the pressing need for accessible, evidence-based digital solutions. The research centers on the creation of a mobile application specifically designed to address mental health challenges. By integrating cognitive behavioral therapy techniques and features like appointment bookings and mindfulness feedback tools, the app is positioned to improve user outcomes. Utilizing platforms like React Native and React, combined with NestJS for enhanced backend security, the application adheres to the rigorous standards required for mental health interventions. Collaborative efforts with experts, notably the counseling unit of IIUM, ensure the app's alignment with contemporary best practices and research. Preliminary findings indicate a promising tool with the potential to address the global mental health treatment disparity.

All things connected to the Internet have to ensure interoperability between each other. Web of Things (WoT) is an Internet of Things (IoT) Web standard technology that enables the communication between smart devices and web-based applications. In order for WoT to be possible, monitoring of all devices connected to the Internet have to be possible. To this end, various efforts are being made to develop network monitoring applications using the latest Web front-end frameworks, not traditional web-based monitoring. This paper examines and describes the possibilities of applying Web front-end frameworks such as React, Angular and Svelte to the development of network monitoring applications for WoT. This paper also describes the pros and cons of two major frameworks, React and Angular, in developing monitoring applications that support the cross-platforms and cross-browsers in WoT environments and examines the applicability of them by developing simple network monitoring applications using React.

연구개발특구진흥재단의 2021년 모바일 증강현실 시장 보고서에 따르면 스마트폰의 발전과 더불어 모바일 증강현실 시장의 성장으로 인해 최근 증강 현실 시장이 성장하고 있다. 증강현실 서비스를 모바일 사용자에게 제공하기 위해서는 기기별 네이티브 앱을 제작해야 한다. 하지만 이에는 멀티 플랫폼 대응에 소비되는 유지보수 비용과 앱 다운로드로 인한 낮은 접근성 등의 문제점이 존재한다. 최근에는 WebXR Device API를 활용하여 웹 환경에서 증강현실 시스템을 구축이 진행되는 추세이나, WebXR Device API를 사용한 시스템은 아직 연구단계에 있다고 판단된다. 본 논문에서는 WebXR Device API, Three JS, React를 이용하여 반응형 멀티 플랫폼 환경을 구축하여, 모바일 및 웹 사용자에게 증강현실 서비스를 제공하는 기능을 구현하였다. 실험 결과 반응형 웹 환경에서 증강현실의 연동을 성공적으로 구현되었음을 확인하였으며, 향후 웹 기반에서 동작되는 증강현실 서비스를 기대해본다.

The students' beliefs about mathematics teaching-learning come from the social activities in mathematics classrooms; and the mathematics classroom culture to a large extent decides the social activities in mathematics classrooms. So, the students' beliefs about mathematics teaching-learning are decided indirectly by the mathematics classroom culture mainly. The students' beliefs about mathematics teaching-learning react to the social activities in mathematics classrooms, and the social activities in mathematics classrooms react to the mathematics classroom culture. Therefore, the students' beliefs about mathematics teaching-learning react indirectly to the mathematics classroom culture. So, the relationships between the students' beliefs about mathematics teaching-learning and the mathematics classroom culture are dialectic, and the social activities in mathematics classrooms are the medium. In addition, the relationships have some inspirations to the current mathematics curriculum reform in the mainland China.

전체적인 조선 생산일정계획을 수립하기 위해서 계층적 구조를 채택하였다. 이 구조에 의하면 도크의 상위 일정계획 생성기는 탑재 일정계획을 생성하고, 조립공정의 하위 일정계획 생성기는 상위 일정계획 생성기가 요구하는 범위 내에서 각각 세부적인 조립 일정계획을 세우게 된다. 그런데 하위 일정계획 생성기가 아무리 노력하여도 상위 일정계획 생성기로부터의 제약조건을 만족시킬 수 없는 상황이 발생하면, 일정계획 수정기에 통보하여 초기 탑재 일정계획을 수정해야 한다. 하위 일정계획 생성기로부터의 조정요청을 반영하기 위해서 부분 수정을 통해 충격을 최소화시키는 일련의 휴리스틱으로 구성된 알고리즘을 제시하였다. 각각의 휴리스틱은 여유시간 제거, 버퍼 제거, 작업시간 축소, 다단계 여유시간 제거, 과부하 자원 공유블럭 조정, 자원 제약조건 완화 등이고, 흡수되지 않은 일부의 충격은 주변으로 전파된다. 이와같은 방법론을 대우조선의 상황에 적용하여, 조선일정계획 수정 시스템인 DAS-REACT를 개발하였다.
