Imagination plays a critical role in travel decision-making. Given the intangible nature of tourism products, tourists cannot directly experience and evaluate the tourism resources in advance. Thus, tourists must first mentally predict and imagine the future travel experiences and scenarios in the destination based on the marketing information (e.g., travel photo, promo video) and prior knowledge, then form their subjective evaluation of the travel product. This future-thinking process is called “mental simulation”. Stacks of research have shown that mental simulations positively affect travel behavior (Le et al., 2019). However, given that travel is a kind of novelty-seeking activity, tourists are usually not familiar with the destination environment and activities. The lack of prior knowledge might inhibit their mental simulation process, even if destination photos and videos are provided. Thus, how to effectively arouse tourists’ mental simulation of destination experience is an important question for effective tourism marketing.

본 논문은 린다 허쳔과 마그리타 레라의 번안 이론을 활용하여 소포크레스의 오이디푸스왕를 번안하는 예이츠와 맥기니스의 동기를 역사적 맥락에서 분석 한다. 주제와 파토스에 있어서 아주 상이한 번안을 하도록 하는 각 저자의 시대상황과 사정이 다른 점들을 보여준다. 또 그리스 원전의 번안 방법에도 주의한다. 본 연구는, 저자들의 빈약한 그리스어를 감안하여, 번안작가들은 언어간의 번역보다는 언어내부적 문제를 더 효과적으로 다룬다. 이 논문은 또한 그들이 어떻게 오이디푸의 신화와 현대 및 당대의 아일랜드 극에 기여하는지 연구하기 위해서 그들의 번안/번역/교정을 할 때 예이츠와 맥기니스가 시도한 변형과 차이를 준 것들이 무엇인지도 논의한다.

Courses on the motion and operation of remotely operated vehicles (ROV) tend to feature abstract theoretical concepts, numerous formulas, combinations of mathematical and physical concepts and teaching that is disconnected from practice. As with the development of computer technology, the dynamic connection between the combination of the highly-realistic visual effects of simulation and theoretical classroom teaching has the aesthetic characteristics of a physical science. In this study, a virtual teaching platform for ROVs was developed on the basis of current virtual simulation technologies, as well as the needs of courses focused on ROV motion and operation. Based on detailed analyses of the functional and performance requirements of a virtual teaching platform for ROVs, the system was subdivided into six subsystems: remote-control simulation, dynamic and kinematic mathematical modeling, underwater operation tools simulation, visual scene display, teacher control and network administration, using an object-oriented design method featuring modularization and standardization. The subsystems facilitate modular development, integration and function extension, and support the openness, inheritance and reusability of the system. The platform is used to intuitively acquaint students with ROVs’ kinetic characteristics and operating methods by means of intuitive 3D models, precise motion calculation, and real operating scenes. Based on teaching practice in colleges and universities, a typical work-task-oriented practical teaching system was developed, along with the application of course design and scenario design for the ROV virtual teaching platform. Through interactive operation, students can dynamically and intuitively observe the motion of ROVs during navigation, helping them to learn about hydrodynamic performance. With simulated ROV operation, students learn about the principles of dynamic mechanical tools as well as the relationships between the interaction forces of ROVs. This contributes to disciplinary progress in naval architecture and ocean engineering, as well as the development of students’ practical engineering competence.

예이츠의 일본의 노드라마와의 조우는 1916년『매의 우물』을 쓰게 하는데, 이 작품에서 그는 시극에서 직면한 여러 문제와 자신의 시적 문화주의의 애매한 표현에 대한 해결책을 찾는다. 노드라마를 그대로 재현하는 대신에 예이츠는 대중적 연극개념에 반대한 자신의 미학적, 정치적 이상을 담아 재창조한다. 예술적으로, 예이트는 “극의 형식을 발명”해내는데, 이 형식은 반연극적, 반사실주의적 화법을 실행할 뿐 아니라, 일반대중을 포용하기를 거부하는 친밀한 극을 만든다. 정치적으로, 예이츠의 시적문화주의는 노에 영감을 받은 극에 적합한 신비주의철학과 결합한다. 시극은 이미지의 집중이 애국심을 불러일으키는 강력한 의식이어야 한다고 예이츠는 생각했다. 그러나 이런 공연 리추얼이 야기하는 주술적 상태는 부정적 양상을 초래한다. 매의 우물에서, 쿠훌린의 마지막 영웅적 행위는 자신의 선택이 아니라 주술의 결과이다. 이렇게 이 극은 초기극『캐스린 니 훌리한』에서 보이는 문화적 주술의 시학으로서의 문화주의의 지속성에 우리의 관심을 끌게 한다.

In the present work, a comparative study of the mechanical behavior of two series of elastomeric composites, based on carboxylated styrene butadiene rubber (X-SBR) and reinforced with rice bran carbon (RBC) and graphite, is reported. Hybrid composites of X-SBR filled with RBC-graphite were also investigated in terms of the cure characteristics, hardness, tensile properties, abrasion resistance, and swelling. It was observed that the cure times decreased with the incorporation of a carbon filler whereas the torque difference, tensile strength, tensile modulus, hardness, and swelling resistance increased compared to the neat X-SBR revealing a favorable characteristic of crosslinking. Dynamic rheological analysis showed that the G' values of the composites, upon the addition of RBC-graphite, were changed to some extent. This demonstrates that the presence of a strongly developed network of fillers will ensure a reinforcing characteristic in a polymer matrix.

Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.

In this paper, we present observations of absorption line spectrum of QSO 1225+317 with resolution of 18 km sec-1. Four possible new heavy element line systems are identified. The properties of Lyman α forest lines are discussed.

Based on the database of 128 disk galaxies (66 SO, 62 S and Irr) mailnly compiled from Kent and Gunn (1982) and Doi et a1.(1995) which is complete down to m < 15.6 mag within a radius of 3°, the orientation of spin vectors of disk galaxies of the Coma cluster has been analyzed. The results confirm the morphological dependence of the orientation of disk galaxies found from the analsis of the Virgo cluster. Common features of orientation of disk galaxies of both clusters are outlined.

The study aims to answer why the previous studies find the positive or insignificant effect of the CEO's abilities on firm performance. Using 34,285 CEO-firm-year panel data from the U.S. publicly traded firms drawn from the BoardEx and EXECUXOMP database during from 1992 to 2014, the results show that the fit of the CEO‟s generality or specialist ability with firm strategy matters on firm performance and risk. This study computes a discrete STRATEGY composite measure to construct firm strategy types, such as Prospect or Defend and use CEOs‟ résumés to construct an index of general skills that are transferable across firms and industries. The results find that generalist CEOs are more suitable for prospectors than specialist CEOs. Firm performance is much better when specialist CEOs work for Defenders. Although the firm performance is better too for the generalist CEOs who fit for the Prospect strategy, the firm‟s risk is up too. The result suggests that firms need to consider their chosen business strategy to recruit and select CEOs Our findings provide direct evidence that the match between CEO‟s ability and the firm‟s strategy is crucial to firm performance and risk.
