Web-scale open information extraction (Open IE) plays an important role in NLP tasks like acquiring common-sense knowledge, learning selectional preferences and automatic text understanding. A large number of Open IE approaches have been proposed in the last decade, and the majority of these approaches are based on supervised learning or dependency parsing. In this paper, we present a novel method for web scale open information extraction, which employs cosine distance based on Google word vector as the confidence score of the extraction. The proposed method is a purely unsupervised learning algorithm without requiring any hand-labeled training data or dependency parse features. We also present the mathematically rigorous proof for the new method with Bayes Inference and Artificial Neural Network theory. It turns out that the proposed algorithm is equivalent to Maximum Likelihood Estimation of the joint probability distribution over the elements of the candidate extraction. The proof itself also theoretically suggests a typical usage of word vector for other NLP tasks. Experiments show that the distance-based method leads to further improvements over the newly presented Open IE systems on three benchmark datasets, in terms of effectiveness and efficiency.

Purpose: This study was done to identify self-directed learning readiness, achievement goal orientations, learning satisfaction and learning achievement, and to evaluate the factors affecting learning achievement for nursing students using a web-based Health Assessment e-Book. Methods: The research design was a cross-sectional study with a structured questionnaire and data were collected before using the web-based Health Assessment e-Book and 1 week after finishing. The participants were 80 nursing students who were taking the Health Assessment class from March to June 2009. Results: Mean score for subjective learning achievement was 31.26 and for objective learning achievement, 69.25. Subjective and objective learning achievement were positively correlated with self-directed learning readiness, mastery goal, attitude toward distance education, and learning satisfaction. In subjective learning achievement, learning satisfaction and mastery goal were significant predictive factors and explained 64% of the variance. Objective learning achievement was significantly predicted by learning satisfaction and self-directed learning readiness, which explained 24% of the variance. Conclusion: Learning satisfaction, mastery goal and self-directed learning readiness were found to be very important factors associated with learning achievement for nursing students using a web-based Health Assessment e-Book. To provide high quality and effective web-based courses and to improve nursing students' learning achievement and learning satisfaction, educators should consider the learner's characteristics from the initial stages of lecture planning.

Even though the distance education via Web has a great advantage to overcome time and space, its problem that the management of trainees is not efficient compared with classroom and group education. This problem is a great obstacle to the objects and achievement standards of distance education, giving controversial arguments to the advocators of distance education. Distance educators need to monitor the trainees 'participation and responses continuously and offer appropriate feedback to the trainees. However, the existing distance education system only focuses on teaching and teaming activities, and as a result, the efficient management function of distance education is not available. Accordingly, the study attempts to find out the appropriate managing elements of distance teacher training in order to effectively achieve the goals of teacher training and the efficient management of distance education. Also, it proposes distance teacher training system that offers appropriate feedback to trainees, applying the derived elements of distance teacher training to the training processes. To verify the efficiency of the system, hypotheses on related items of distance teacher education and learning types are suggested, and the achievement of learning and its relations are investigated through questionnaire of learning types.

This study examined the effect of using web-based distance program in home health education for nursing college students in COVID-19 special disaster area. The study was carried out according a nonequivalent control group pretest-posttest design. The study subjects were 49 nursing college students from K City, Gyeongsangbuk-do. The web-based distance program was conducted for 2 weeks. The data collection period was from June 1, 2020 to June 12, 2020. Collected data were analyzed using SPSS PC+ 19.0 with the Fisher' exact test, Wilcoxon rank sum test, ANCOVA with pretest value as covariate. The experimental group had significantly different in knowledge related home health nursing, perceived motivation, and learning commitment in comparison to the control group. This suggests that the web-based distance program in the COVID-19 special disaster area can be applied as a way to increase nursing students' knowledge related home health nursing, perceived motivation, and learning commitment.

The rapidly developing World Wide Web technology provides new opportunities for distance education over the internet. Several successful experiments about cyber educationor distance leanning have been reported. The Web when combined with other network tools can be used to create a virtual classroom to bring together a community of learners for interactive education. Requrements for standard tools for distance. Iearning, such as an electionic mail, a multiparheipant bcard newsgroup service and video conference tools have been investigated and implemented based on the object modeling technique useing java programming language. The object onented programming helps the developed codes maintain learning with allowed interactions either between instroctors and students or between students.

In the distance education systems, there are limited things while performing educational activities because there are to be problems in structural features of the Web. HTTP, a connection-less protocol, performs requests of client, however, does not hold on the status. Thus, by features of the Web, it is difficult to hold on the connection of learners and trace information asked by learners. Moreover, these problems make impossible not only a learner's connection continuity but also on-line interaction among the learners in the distance education. This thesis developed CHTP, an connection-based hypertext transfer protocol, based on HTTP and a new platform of distance education in order to track activities of learners. The developed web extension platform will make it easy to build up system for being helpful in a distance education because this thesis proposes a standardized way in the protocol.

Purpose: The purpose of this study is to identify the nursing student's e-Learning status. Method: The 48 nursing students were subject to this study. They were introduced to use 'understanding of ABGA' site. And the web log data was analysed. Result: General learning status in nursing education, difference of learning status in each learning type, and 'quiz' area learning status were analysed to see the nursing student's e-Learning status. The result of study showed that the participants didn't get learning that site designer had in mind to give them. Conclusion: It is important to figure out students' actual learning behaviors and reactions of feedbacks. Also, web log data could provide useful data that affect student's behaviors. Based on this study result, the following is suggested. The way to give them effective learning should be considered by the instructor who knows the unsincere type students through web log data.

Nowadays, the computational capability and graphical power based on PCs increase very rapidly every year. As a result, the complicated engineering or scientific problems that could have only been handled by supercomputers a couple of decades ago can now be routinely run on PCs. Besides, the PCs can be assembled in parallel to increase its computational capability theoretically without limitation. The Web-based interface and communication tools are also being enhanced very rapidly and the real-time distance learning (E-Learning) and project cooperation on web get increasing attention. Using the-state-of-the-art computational method, a number of complicated and computationally intensive problems are being solved by PCs. The results can be well demonstrated on screen by graphics and animation tools. Those examples include the simulations of fully nonlinear waves, their interactions with floating bodies, global-motion analysis of multi-unit floating production system including complicated mooring lines and risers. Several examples will be presented in this regard. Also, Web and java-applet based educational tools have been developed at Texas A&M University for better understanding of waves and wave-body interactions. The background and examples of such Web-based educational tools published in Kim et al. (2003) are briefly introduced here.

Although distance education system based on WBI theory has already been generalized in domestic universities and some private academical institutes, the use of the system in the real fields of schools is in the early stage now. In this paper, we develop a model of English learning system for middle school students and improve students' learning methods through the system. The system also makes students study all the learning topics which they choose in the system freely and repeatedly. It was applied to the middle school students. The analysis of the application showed the following results. First, it was very effective for students to achieve the learning objectives of the course of English. Second, the system made students improve their abilities to study English and also increase their abilities to surf the Internet and glean useful information. Third, the system made it possible for students to accomplish individual learning.
