The purpose of the present study was to examine the effect of 3D avatar-based Virtual Reality chatting on college students' English learning achievement. Forty college sophomore students participated at this study and the research lesson continued for 8 weeks. They were administered to take a pretest to evaluate their vocabulary knowledge and writing skills. Their progress was assessed on the basis of midterm. Finally, a post-questionnaire was administered to measure their interest and understanding toward their learning experience in 3D avatar-based Virtual chatting. The results of this study indicated that there was a statistically significant difference between the control group and experimental group with respect to their midterm scores and writing. The result of the post-survey indicated the interest of English was statistically higher than the understanding of English.

This study examines the structural relationships between ecotourism village visitors' motivation, value, satisfaction, and loyalty. A self-administered survey was conducted based on 254 visitors to six ecotourism villages. According to the confirmatory factor analysis, there were four underlying dimensions of motivation (relaxation, adventure, nature experience, and learning) and on underlying dimension of value (tourism). According to structural equation modeling, relaxation had a positive effect on economic value, and relaxation and learning had positive effects of functional value. Relaxation had a positive effect on social value. Economic, emotional, and social value had positive effects on ecotourism village visitors' satisfaction, and economic value had the greatest effect on satisfaction. Satisfaction had a positive effect on destination loyalty. The results imply that economic, emotional, and social value played important mediating roles in the relationship between motivation and satisfaction.

The purpose of this study was to explore an intrinsic concept of 'company innovativeness' based on qualitative data obtained from 54 practitioners with at least 5 year-experience in the industry. Data were analyzed based on the grounded theory and Nvivo 2.0 program. Based on results, seven theme were generated. Seven intrinsic theme include 5 intrinsic concepts such as learning orientation, excellence of human resource, treatment for employees, market orientation and work efficiency, and 2 performance concepts such as business performance and innovation performance. These diverse concepts were considered as an important guideline in judging whether a company is innovative or not. In addition, diverse programs were provided by companies for a purpose of enhancing company innovativeness. Based on results, a research model was suggested to be elaborated in future studies. Implications and suggestions were generated based on results.

Studies on the ship's automatic navigation & berthing control have been continued by way of solving the ship's mathematical model, but the results of such studies have not reached to our satisfactory level due to its non-linear characteristics at low speed. In this paper, the authors propose a new berthing control system which can evaluate as closely as cap-tain's decision-making by using the FNN(Fuzzy Neural Network) controller which can simulate captain's knowledge. This berthing controller consists of the navigation subsystem FNN controller and the berthing subsystem FNN controller. The learning data are drawn from Ship Handling Simulator (NavSim NMS-90 MK Ⅲ) and represent the ship motion characteristics internally. According to learning procedure, both FNN controllers can tune membership functions and identify fuzzy control rules automatically. The verified results show the FNN controllers effective to incorporate captain's knowledge and experience of berthing.

In this paper, the authors propose a new control system which can evaluate as closely as captain's decision-making by using the FNN(Fuzzy Neural Network) controller which can simulate captain's knowledge. This controller contains the concept of safety according to channel width. The learning data are drawn from ship Handling simulator(NavSim NMS-90 MK III) and represent the ship motion characteristics internally. According to learning procedure, the FNN controller can tune membership functions and identify fuzzy control rules automatically. The verified results show that the FNN controller is effective to incorporate captain's knowledge and experience of manoeuvrability in channel.

The aim of this paper was to diagnose Korean college students' listening skills on the TOEFL. The researchers identified which section, among the TOEFL listening Part A, B, and C, is most easily teachable/ improvable during the period of a semester. First, the result of this research shows that Korean students tend to have lower scores in Part A than Part B or Part C. The results indicate that the short informal conversation doesn't give sufficient clues to students, and they don't have enough time to infer the answer. Second, the results revealed that. students showed the lowest progress in Part B after they studied TOEFL listening items and essential idioms for the listening section for 13 weeks. Because students didn't have much experience learning the informal conversation as opposed to the formal one in English, it is harder to achieve an improved grade in Part B, which consists of the informal conversation. But after a semester-long listening course, the average score on TOEFL listening sections increased.

In this paper, we apply mathematising activities to geometry contents of corrent in middle and high school in order to actualize learning and teaching through Freudenthal's, Piaget's, and Van Hieles's mathematising among many theories affecting teaching and learning methods. Learners find out mathematical idea through the activities of mathematising that interprete mathematical problemm. And we derive mathematic through the experience of vertical mathematising that expresses it. Based on it, Freudenthal's progressive mathematising process, etc are used in doing the activities of applicative mathematising.

The purpose of the study was to develop evaluation methods which would measure student achievement and progress without traditional paper-pencil tests such as mid-term and final examinations. More specifically, the main research focus were to establish general directions of student assessment during free semester, to build evaluation models supporting student's participation and learning, and to report and record various student evaluation results. As research results, we found that student evaluation of free semester should be organized to improve a) experience learning activity, self-regulatory and collaboratory study, b) high-order thinking ability and character-building, and c) teacher-student-parent cooperation. Since traditional paper-pencil tests were restricted in free semester, student achievement should be provided by a way of performance descriptions on transcripts rather than quantitative grade points. Student performance descriptions had to show not only subject knowledge but also students efforts, motivation, and participation. These multiple and educationally meaningful information would be collected by teacher-student-parent communication and collaboration.

As far as the recent ELT research concerned, it seems to have been no hot ‘theoretical’ issues, but ‘practical’ ones in general: e.g., learners and learning, components of proficiency, correlates of L2 learning, etc. This paper focuses on the theme given above, with a special reference to the sub-title: specifically, 1) World English, world Englishes and world's lingua franca; 2) ENL, ESL and EFL; 3) Grammars, style manuals, dictionaries and media; 4) Pronunciation models: RP, BBC model and General American, Network Standard; 5) Lexical, grammatical variations and discourse grammars; 6) Beliefs and subjective theories in foreign language research; 7) Dilemma among radical, canonical and eclectic views. In conclusion, the author offers a modest proposal: we need to appeal to our own experience, intention, feeling and purpose, that is, our identity to express “our own selves” in our contexts toward the world anywhere, if not sounding authentic enough, but producing it plausibly well. It is time for us (with our ethno-cultural autonomy) to need to be complementary to and parallel with its native speakers' linguistic-cultural authenticity in terms of the broadest mutual understanding.

Tin-Can은 SCORM의 한계를 극복하고자 미국 표준제정기관인 ADL(Advanced Distributed Learning)에서 개발하였다. SCORM의 차세대 버전으로 탄생한 Tin-Can은 Experience API (XAPI) 라고도 불리며 학습자가 학습경험을 얻는 과정을 저장하는 도구로써 각광을 받고 있다. 온라인 학습환경에서 중점 중의 하나는 Learning Analytics를 통하여 학습자에게 맞춤형 학습을 제공하는 것이다. 이를 위해서는 학습자의 활동 정보(Activity Data)를 데이터베이스화하는 것이 중요한데 위와 같은 기능들을 모두 제공해 줄 수 있는 것이 Tin-Can이다. 본 논문에서는 Tin-Can에 대해 설명하고, 온라인 학습환경에서 Tin-Can을 접목하여 학습 활동 정보를 수집하는 방법에 대해서 설명한다.
