Introduction: Surgery and anesthesia are the common practice for anesthetist on the one hand and very worrying for the patient and his family on the other. This fear can have potentially dangerous consequences. The aim of this study was to determine the relationship between the awareness and fear of patients and their companions towards anesthesia. Methods: The present study employed a descrip...

Curiosity is an emotional motivation that drives knowledge acquisition in learning context. Studies have shown that curiosity positively influences social learning and a peer learner’s curiosity may elicit the curiosity of other learners. Hence, modeling curiosity in learning companions may improve human learners’ learning experience in virtual environments. However, curiosity has not been expl...

This paper summarizes the results of over 17 years of work searching for low mass stellar and substellar companions to more than 370 nearby white dwarfs. Roughly 60 low mass, unevolved companions were found and studied all together, with over 20 discovered in the last few years, including the first unambiguous brown dwarf companion to a white dwarf, GD 1400B. The resulting spectral type distrib...

in the battle of tabuk, unlike other battles, the participation of muslims was very weak and their procrastinations caused to be delayed in the preparation of the army and the move toward tabuk. some of the companions expressed one’s regrets for being unable to participate in this battle. in the sura of tawba, god exposes the intentions of these non-participants, expressing their real reasons f...

This paper presents results of a near-infrared imaging survey for low mass stellar and substellar companions to white dwarfs. A wide field proper motion survey of 261 white dwarfs was capable of directly detecting companions at orbital separations between ∼ 100 and 5000 AU with masses as low as 0.05 M⊙, while a deep near field search of 86 white dwarfs was capable of directly detecting companio...

Educational agents (including animal companions) are a kind of interface agent, which is a significant component in educational systems, and has great impacts on student learning. However, with the development of emerging technologies (e.g., tangible technology), few studies have yet investigated how tangible technology can be used to combine with animal companions to foster student learning an...

The masses of compact objects like white dwarfs, neutron stars and black holes are fundamental to astrophysics, but very difficult to measure. We present the results of an analysis of subluminous B (sdB) stars in close binary systems with unseen compact companions to derive their masses and clarify their nature. Radial velocity curves were obtained from time resolved spectroscopy. The atmospher...

This study investigates perceptions of organizational image and attractiveness among 200 potential applicants for the Belgian Defense and the person (e.g., friend, parent) accompanying them to a job fair. The instrumental-symbolic framework is applied to conceptualize the key dimensions of an organization‟s image as an employer. The results indicate that instrumental image attributes predict pe...

This paper describes the evaluation of our fully integrated virtual game companions framework (ERiSA) [4]. We conducted three user studies with different scenarios using two versions of The Smile Game[4] in semi-public and public spaces. In our study, we show that the game companions’ personality was successfully perceived by the participants while interacting and playing with the game companio...
