在韩国,"中文热"由来已久,最早可追溯到三国时期.中韩两国是近邻,从与平民百姓做贸易时有关的翻译,到与政治外交公文书有关的写作,毋庸置疑都需要"中文人才".当时还未出现专门教授中文的大学,只能由官方主管设置一些机构来教授中文,并且从古代三国开始到高丽、朝鲜一直继承教授中文的传统.虽然各个时期的中文教育机构在"名称"上有所不同,但在课程设置方面或多或少都涉及到中国语言、文学等方面的科目,并且随着时间的推移,与中国有关的学科越来越细化并趋向专业化. 相似文献

The relationship between materialism and social-emotional behavioural difficulties (SEBDs) was assessed by comparing a sample of adolescents receiving in-school behavioural support with adolescents not receiving any support. All participants completed the Youth Materialism Scale and the Strengths and Difficulties Questionnaire. Binary logistic regression indicated that adolescents who reported higher levels of materialism were more likely to be classified into a group considered ‘at-risk’ for developing conduct and peer problems. Hierarchical logistic regression assessed the moderation of behavioural support and indicated that adolescents in receipt of behavioural support who reported higher levels of materialism were at a greater risk of hyperactivity in comparison to those who receive support but reported lower levels of materialism. For adolescents not receiving behavioural support, less materialistic attitudes placed them at a greater risk of hyperactivity. These findings highlight the importance of distinguishing between different SEBD typologies and the potential effects of materialism during adolescence. 相似文献

With a limited budget, but a critical need to develop 21st century marketplace skills, Georgia Perimeter College (GPC) developed the Million Dollar Difference Campaign. Focusing on how quality instruction affects retention and student outcomes, GPC re-energized a 1000-faculty workforce in one year through a series of innovative teaching strategies. Data were collected that proved the campaign worked. 相似文献

ABSTRACT In this article, the authors introduce a novel way, using the metaphor of a baseball game, to evaluate and measure community college student progress for those whose stated goal is to transfer to a 4-year institution and, ultimately, earn a bachelor's degree. The proposed framework of “the Transfer Game” is an outgrowth of the Transfer and Retention of Urban Community College Students (TRUCCS) project, which is a longitudinal study of 5,000 community college students from the 9-campuses of the Los Angeles Community College District. The goal of the project is to explain how the “all-American game” provides a method to measure, comprehend, and visualize student progression, and identify the factors that predict both success and barriers. The framework provides a scholarly comparison of the all-American game of baseball to the All-American invention of the community college. 相似文献

In this paper, we consider the super-twisting observer-based sliding mode control algorithm with fuzzy variable gains (STOSMC) for the fully-actuated hexarotor. Our hexarotor has full actuation due to six titled propellers that allows to control position and orientation (attitude) simultaneously, and resolves the singularity problem of the rotational matrix by using the quaternion modeling framework. We show that the proposed STOSMC for the hexarotor guarantees finite-time convergence of the estimation error and asymptotic stability of the hexarotor. In simulations, we demonstrate the nonsingularity and fully-actuated control performance of the hexarotor by considering extreme position and attitude control scenarios. Moreover, the simulation results show that the hexarotor achieves the fast and precise tracking performance to the desired position and the desired attitude and the chattering phenomenon is reduced compared with the fixed-gains observer-based super-twisting sliding mode control due to the fuzzy mechanism. 相似文献

Soft robotics with new designs, fabrication technologies and control strategies inspired by nature have been totally changing our view on robotics. To fully exploit their potential in practical applications, untethered designs are preferred in implementation. However, hindered by the limited thermal/mechanical performance of soft materials, it has been always challenging for researchers to implement untethered solutions, which generally involve rigid forms of high energy-density power sources or high energy-density processes. A number of insects in nature, such as rove beetles, can gain a burst of kinetic energy from the induced surface-energy gradient on water to return to their familiar habitats, which is generally known as Marangoni propulsion. Inspired by such a behavior, we report the agile untethered mobility of a fully soft robot in liquid based on induced energy gradients and also develop corresponding fabrication and maneuvering strategies. The robot can reach a speed of 5.5 body lengths per second, which is 7-fold more than the best reported, 0.69 (body length per second), in the previous work on untethered soft robots in liquid by far. Further controlling the robots, we demonstrate a soft-robot swarm that can approach a target simultaneously to assure a hit with high accuracy. Without employing any high energy-density power sources or processes, our robot exhibits many attractive merits, such as quietness, no mechanical wear, no thermal fatigue, invisibility and ease of robot fabrication, which may potentially impact many fields in the future. 相似文献

This paper proposes a set of methods and a framework for evaluating, modeling, and predicting group interactions in computer‐mediated communication. The method of sequential analysis is described along with specific software tools and techniques to facilitate the analysis of message–response sequences. In addition, the Dialogic Theory and its assumptions are presented to establish a theoretical framework and guide to using sequential analysis in computer‐mediated communication research. Step‐by‐step instructions are presented to illustrate how sequential analysis can be used to measure the way latent variables (e.g., message function, response latency, communication style) and exogenous variables (e.g., gender, discourse rules, context) affect how likely a message is to elicit a response, the types of responses elicited by the message, and whether or not the elicited sequence of responses (e.g., claim → challenge → explain) mirror the processes that support group decision‐making, problem‐solving, and learning. 相似文献

Expression and Reception: An Analytic Method for Assessing Message Production and Consumption in CMC
Kang Namkoong Dhavan V. Shah Bryan McLaughlin Ming-Yuan Chih Tae Joon Moon Shawnika Hull 《Communication methods and measures》2017,11(3):153-172
This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks. 相似文献

The purpose of this study is to develop the evaluation factors for the Subject Guide for Korean Modern Literature, which is provided by the National Library of Korea, to enhance the guides as an effective public service. In the study, the following final evaluation factors were identified: four evaluation domains (use, content, format, and collaboration), 23 evaluation components, and 67 evaluation items and questions. The results of the study showed that key evaluation components included the reliability of the website, user communication, accessibility to the subject guides, book search capability, provision of information in a consistent format, and the scope of the subject guides. When the subject-specific bibliography system of the National Library of Korea was examined by applying the developed evaluation factors, it was found that the system satisfied only 37 (55.2%) of 67 evaluation items: 8 (40%) of 20 items on use, 13 (66%) of 20 items on content, 15 (88%) of 17 items on format, and 1 (10%) of 10 items on collaboration. Accordingly, the entire subject-specific bibliography system that is currently in use needs to be reviewed, and changes and improvements need to be made utilizing the derived evaluation factors. In particular, it is imperative to develop a strategy to facilitate collaboration among users and librarians in charge, and a more effective subject guide system. 相似文献
