본 연구는 흔히 미니 홈피로 불리는 개인 웹사이트(personal website)의 자기 제시(self-presentation)에 대한 평가가 어떠한 요인들에 의해 영향 받는지를 알아보고자 한 것이다. 성별, 자아 구성, 자아 존중감, 자기제시 방식을 주요 설명변인으로 놓고 개인 웹사이트 주인에 대한 호감도와 유능감을 종속변인으로 한 구조방정식모형(SEM)을 검증해 보았다. 또한 잠재평균분석(LMA)을 통해서 구인된 변인들 간에 남녀 집단에서 차이가 존재하는지도 살펴보았다. 분석 결과, 여성이 남성에 비해 상호의존적 자아구성 성향이 높은 것으로 나타났다. 또한 남녀 모두 동성보다는 이성의 자기 제시에 대해 높은 호감도를 보였고, 동성의 과시형 자기 제시에 대해서는 상대적으로 낮은 호감도를 보였다. 한편, 지각된 유능감 측면에서도 남녀 모두 이성의 자기 제시에 대해 보다 유능하다는 평가를 하고, 여성의 경우에는 과시형 자기 제시를 한 남성에 대해 더욱 유능하다고 평가한 것으로 나타나, 자기제시자의 성별에 따라 평가가 크게 달라짐을 알 수 있었다. 한편, 자아구성과 자아존중감은 성별의 효과에 비해 일관적이지도 않고 상대적으로 약한 영향을 미치는 것으로 나타났다. 이러한 현상은 오프라인에서의 자기제시에 대한 기존의 많은 연구와는 상당한 차이를 보이는 결과다. 이러한 차이가 웹사이트라는 특성에 기인한 것인지의 여부에 답하기 위해서는 다른 조건들을 동일하게 놓고 온라인과 오프라인의 자기제시 효과를 비교하는 후속 연구가 필요 할 것이다. 본 연구의 결과는 방문자에게 호감을 주는 개인 웹사이트를 만들기 위해서는 방문자의 특성(특히 성별)을 고려한 자기 제시 유형을 전략적으로 활용해야 함을 암시한다.

This paper aims to explore instructional design of a cyber classroom for secondary students' basic English language competence. A paucity of support for low or under achieving students' English learning exists particularly at the secondary level. In order to bridge the gap, there has been demand for online educational resources considered to be an effective tool in improving students' self-directed learning and motivation. This study employs a comprehensive approach to instructional design for the asynchronous cyber classroom with the underlying premise that different learning theories can be applied in a complementary manner to serve different pedagogical purposes best. Gagné's conditions of learning theory, Bruner's constructivist theory, Carroll's minimalist theory, and Vygotsky's social cognitive development theory serve as the basis for designing instruction and selecting appropriate media. The ADDIE model is used to develop online teaching and learning materials. Twenty-five key grammatical features were selected through the analysis of the national curriculum of English, being grouped into five units. Each feature is covered in one cyber asynchronous class. An Integration Class is given at the end of every five classes for synthesis, where students can practice grammatical features in a communicative context. Related theories, pedagogical practices, and practical web-design strategies for cyber Basic English classes are discussed with suggestions for research, practice and policy to support self-directed learning through a cyber class.

Purpose: This study was conducted to identify the professional competency of nurses working in emergency medical institutions that use the Korean Triage Acuity Scale (KTAS), and to identify factors that affect them. Methods: This study collected data from 105 nurses working in emergency medical institutions from June to August 2020. For data analysis, descriptive analysis, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression were performed using the SPSS 25.0 program. Results: As for the professional competency in triage, the higher the self-efficacy (β= 0.58, p< .001), the more experience they have in triage-related education (β= 0.30, p< .001), 2-4 years of clinical experience in emergency department (β= 0.19, p= .002), in case of triage alone (β= 0.24, p< .001), the higher the level of education a nurse has (β= 0.19, p= .003), the higher the professional competency in triage. These variables explained professional competency in a total of 64.2% of the participants (F = 38.30, p< .001). Conclusion: To improve nurses' professional competence in triage, introducing manpower expansion, financial support, and the provision of appropriate places is suggested. In addition, it is necessary to repeatedly provide educational opportunities in an environment similar to actual clinical practice by developing various scenarios and introducing simulations and web-based formats.

In the new web based learning environment which has recently emerged, a variety of new learning objectives and teaching methods suited to this learning environment have been adopted. Recently, web based project-based learning methods have received a great deal of attention from those wishing to improve learning performance. The objective of this study is to identify the impact of characteristics of communication media and instruction behavior on collaborative interaction and project performance through web based group projects. The characteristics of communication media were divided into richness, flexibility, and ease of use, and the characteristics of instruction behavior were divided into support and expression, which are independent variables. Collaborative interaction as a mediate variable, was divided into information sharing and negotiation. Project performance was the dependent variable. To verify the proposed research model empirically, an experiment was conducted in which learners participated in on-line and off-line courses with group projects. The group project was conducted virtual product development(VPD), and designed a web-site about the VPD. At the end of the project, a survey was conducted. Of the 270 students, 239 responded. The students were assigned to groups of 3 or 4 members, and represented different genders and levels of computer competence. The reliability, validity, and correlation of research variables were analyzed using SPSS 14.0, and the measurement model and the structural goodness-of-fit of the research model were verified through SEM analysis using Lisrel 8.54. We found important results as follows; First, richness and ease of use has positive impacts on each of sharing information and negotiation. This suggests that richness and ease of use are useful in sharing information which is related to the task and agreeing in opinions among group members. However, flexibility has not positive impacts on sharing information and negotiation. This implies that there is no great difference in performance of PC and information literacy of user. Second, support and expression of instructor have positive impacts on sharing information and negotiation. This indicates that instructors play an important role in encouraging learners to participate in the project and communicating with them, sharing information related to the project, making a resonable decision and finally leading them to improve a project performance. Third, collaborative interaction has a positive impact on project performance. This result shows that if the ability to share information and negotiate among students was improved then a project performance would be improved as well. Recently, in the state of revitalized web based learning, it is opportune that web-based group project is practically conducted, and the impact of characteristics of communication media and characteristics of instruction behavior on sharing information, negotiating among group members and improving a project performance is verified. On the basis of these results, we propose that forms of learning, such as web based project, could be one of solution which is to enforce interaction among learners, and ultimately improve learning performance. Moreover web-based group project is able to make up for a weakness which makes it difficult to make interpersonal relations or friendship among learners in computer mediated communication or web based learning.

The core purpose of the system proposed in this paper is to help learners pursue proactive and self-oriented education by allowing learners to proactively configure their own content, that is, learners no longer have to be restricted by prescribed sequence of lectures. Although a variety of standardization and Learning Management System (LMS) were produced to develop and effectively manage web contents in response to active diffusion of internet application, practical changes to assist online learners are not yet to be found. In this paper, I would like to introduce a LMS that can support self-leading education by providing various types of learners at Virtual University with delicately organized educational contents for maximum efficiency. The system allows a learner to select a lecture or a chapter which has been presorted to meet his educational needs and intellectual ability. In general, most LMSs cannot meet every individual's educational needs because they structure their programs by letting learners simply choose from a list of available lectures at prescribed level or difficulty. However the Self-Leading LMS eliminates such boundaries by allowing learners to choose contents and difficulty within the limit set by their own educational competence.

This study examines the use of discourse markers in cross-cultural communication between EFL learners in an e-learning environment. The study analyzes the use of discourse markers in a corpus of an interactive web with a bulletin board system through which college students of English at Japanese and Korean universities interacted with each other discussing the topics of local and global issues. It compares the use of discourse markers in the learners' corpus to that of a native English speakers' corpus. The results indicate that discourse markers are useful interactional devices to structure and organize discourse. EFL learners are found to display more frequent use of referentially and cognitively functional discourse markers and a relatively rare use of other markers. Native speakers are found to use a wider variety of discourse markers for different functions. Suggestions are made for using computer corpora in understanding EFL learners' language difficulties and helping them become more interactionally competent speakers.
