이종 서비스에 텔레프레즌스 서비스 정보 제공 방법

이윤진(Yunjin Lee),김영한(Younghan Kim),최선완(Sunwan Choi) Korean Institute of Information Scientists and Eng 2015 정보과학회논문지 Vol.42 No.1

This paper proposes a method for providing the information about multimedia streams for telepresence services to heterogeneous services such as IMS (IP Multimedia Subsystem) and RTCWeb (Real-Time Communication in WEB-browsers). First of all, we design an interworking gateway for each service and suggest a procedure for providing the information about multimedia streams, which is defined by CLUE, a working group for standardization, to the heterogeneous services. We also apply the method of the actual CLUE information exchange and implement it in our experiment environment. Finally, we show that the proposed method can exchange more information than previous methods even though the media session re-establishment time is similar to legacy systems in terms of performance analysis. With the proposed method, the heterogeneous services can collect a variety of information about the telepresence service and use it according to user preference. In this way it provides rich multimedia streaming services for many areas.

The purpose of this study is to grasp the overall status of the bilingual environment creation project of the Multicultural Family Support Center and investigates how researches on this area should be conducted. The bilingual environment for multicultural families project is a project to support bilingual parent coaching and parent/ child interaction programs for multicultural families with young children. This project has been implemented in earnest since 2015 at the Multicultural Family Support Center (institute under the Ministry of Gender Equality and Family, Korean Institute for Healthy Family). In this study, we focused on four aspects of bilingual environment creation project: 1) Overall overview, 2) Characteristics of operation by detailed project, 3) Education materials, and 4) Dedicated human resources(bilingual coaches). This study is meaningful in that it was the first attempt to focus on the current status of the bilingual environment creation project of the multicultural family support center in the field of Korean language education.

시간적 거리감과 사회적 거리감이 온라인 구전 정보 신뢰도에 미치는 영향

이윤진(YunJin Lee),장예빛(YeBeet Jang),유승호(SeoungHo Ryu) 한국HCI학회 2013 한국HCI학회 학술대회 Vol.2013 No.1

당장 필요한 물건을 구매하려 정보를 탐색할 때와, 미래에 필요한 상품을 구매하려 하려 정보를 탐색 시간의 효과에 따라 구전정보의 효과는 달라질 수 있다. 본 연구에서는 구매와의 시간적 거리에 따라 소비자의 온라인상의 구전정보 수용이 어떻게 달라지는지를 해석수준이론을 바탕으로 분석하여 온라인 구전커뮤니케이션에서 심리학적 측면들이 의미 있게 활용될 수 있는 방향을 고찰해보고자 한다. 해석수준에 대한 선행연구를 통해 구매와의 시간적 거리와 구전정보원과의 사회적 거리가 매칭 될 때 구전이 더 효과적일 것이라 예상할 수 있다. 이에 페이스북 친구를 사회적 거리가 가까운 구전 정보원으로, 블로거를 사회적 거리가 먼 정보원천으로 설정하고, 구매와의 시간적 거리와 소비자가 구전 정보원에 느끼는 사회적 거리가 소비자의 정보수용에 어떠한 영향을 미치는지를 살펴보았다. 그 결과 페이스북 친구의 정보의 경우 구매와의 시간적 거리가 멀 때보다 가까울 때 정보의 신뢰도가 높았으며, 블로거의 구전정보의 경우 구매와의 시간적 거리에 따라 신뢰도가 달라지지 않았다. 또한 구매와의 시간적 거리가 가까울 때에는 블로거보다 페이스북 친구의 구전정보에 더 신뢰도를 느끼는 것으로 나타났으나, 시간적 거리가 멀 때에는 유의미한 차이가 나타나지 않았다. Decision making can be differed by the time effect, for example, a difference is shown between information seeking for the product you need right away, and information seeking for the product needed in the future. Based on the construal level theory, it can be expected that eWOM(electronic word of mouth) would be more effective, when the temporal distance between the purchase matches the social distance between the eWOM informants. Distinguishing Facebook friends as eWOM informants with a close social distance and bloggers as eWOM informants with a far social distance, this study examined how the temporal distance between the purchase and the social distance between the eWOM sources affect the choice of the consumer. The result showed that the information from the Facebook had more effectiveness when the temporal distance between the purchase was close, and the eWOM information from the bloggers had no difference in information credibility according to the temporal distance. Moreover, when the temporal distance between the purchase was close, it showed that the eWOM of Facebook friends had higher credibility than the bloggers , however, when the temporal distance was far, there was no significant difference between the two sources.

학부 교환학생을 위한 한국어 쓰기 교과목 운영 과정에서의 교사 피드백 연구

이윤진(Lee, YunJin) 학습자중심교과교육학회 2016 학습자중심교과교육연구 Vol.16 No.7

본고는 한국어 쓰기 교과목 운영(2012년도 2학기∼2015년도 2학기)의 사례를 기반으로 교육 현장에서 교사가 실질적으로 맞닥뜨리게 되는 피드백의 주요 내용을 수업의 단계별로 고찰한 논의이다. 그간의 교사 피드백 관련 연구가 피드백의 특정 부분에 관심을 두거나 이상적인 피드백 방안 모색에 초점을 둔 것과 달리 본고는 쓰기 교과목의 전반적인 운영 안에서 구현되는 교사 피드백을 중점적으로 살펴보았다는 점에서 차별성을 지닌다. 먼저 Ⅱ장에서는 교사 피드백에 대한 기존 논의를 검토하면서 교육 현장의 적용 가능성에 대한 고려가 절실함을 확인하였다. Ⅲ장에서는 쓰기 교과목 운영의 한 사례로서 연세대학교 학부 교환학생 대상의 교과목 개요 및 특성을 살펴보고 이에 맞게 적용된 교사 피드백의 구체적인 내용을 밝혔다. Ⅳ장에서는 한 학기의 수업을 전제로 교사의 쓰기 피드백을 크게 ‘피드백 전 단계’, ‘피드백 본 단계’, ‘피드백 후 단계’의 3단계로 구분하여 각 단계별 고려 사항과 세부 요인을 고찰하였다. 쓰기 피드백은 단지 교사의 일방적인 헌신과 노력만이 아닌 교수 상황에 맞게 적절한 방법과 수준으로 학습자에게 제공되어야 하고 전반적인 교과목 운영과 긴밀하고 유기적인 관계가 전제되어야 함을 부각시켰다는 데 본고의 의의가 있다. This study provides a phased discussion through contemplation of feedbacks received and confronted by an instigator on an education site, based on real examples of operating an actual Korean writing curriculum. Differentiation is made from existing studies through the study’s focus on the instigator feedback’s occurrence within the general context of Korean writing curriculum operation, whereas previous studies focused singularly on a single and particular aspect of a feedback or was centralized on searching for an ideal curriculum. In chapter II, this paper reviews the pre-established discussions on the present address of an educator’s feedback. In chapter III, an instigator’s feedback is being discussed with an exemplary real-life context of Yonsei University international student’s undergraduate curriculum on Korean Writing, paralleling the discussion with the gathering of curriculum details and characteristics. In Chapter IV, with one semester’s lectures as the foundation, the instigator’s feedback on writing is defined largely into three phases with considerations and details elucidated for each: ‘pre-feedback phase’, ‘during-feedback phase’, and ‘post-feedback phase’.

텔레프레즌스 서비스와 IMS 기반 컨퍼런싱 서비스 연동

이윤진(Yunjin Lee),김영한(Younghan Kim) 한국정보과학회 2014 정보과학회논문지 : 정보통신 Vol.41 No.2

본 논문은 실감 형 영상회의로 알려진 텔레프레즌스 서비스와 IMS(IP Multimedia Subsystem) 기반 서비스 간의 상호 연동을 위한 방법을 제안한다. 본 논문에서는 게이트웨이를 통하여 두 서비스 간의 세션 설립뿐만 아니라 멀티미디어 스트림의 추가적인 정보를 교환하는 절차를 설계한다. 또한 텔레프레즌스 컨퍼런스에 참여하는 IMS 사용자가 증가할 때, 세션 설립 지연시간을 감소하기 위하여 게이트웨이의 SDP(Session Description Protocol) 캐싱 방법을 제안한다. 마지막으로, 세션 설립의 지연시간을 분석함으로써 시스템 성능을 측정한다. 제안된 게이트웨이로, 현존하는 텔레프레즌스 서비스와과 IMS 기반 서비스는 별도의 수정 없이 상호 동작할 수 있다. The paper proposes an approach for interworking between Telepresence service, known as realistic video conferencing, and IMS(IP Multimedia Subsystem)-based conferencing service. We design procedures for establishing the session as well as for exchanging multimedia streams’ additional information between two services via the gateway. Moreover, when the number of IMS users participating in the Telepresence conference increases, we suggest that the gateway should apply a SDP(Session Description Protocol) caching scheme for decreasing the delay time in establishing the session. Finally, the system performance is measured by analyzing the delay time of the session establishment. With the proposed gateway, the existing Telepresence service and IMS-based service can cooperate without any modification.

This study takes a look at Korean language Education from the perspective of lifelong education, and investigates how researches on this area should be conducted. After reviewing current research trends in terms of topic, object, methods and contents, suggestions for improvements are made. First, the necessity of research on Korean language education in the perspective of lifelong education and its social role and responsibility were emphasized. Second, it was found that high expectations are being placed on Korean language teaching for adult immigrants among other learner groups. Various keywords such as immigrants’ life-cycle changes, consequent restructuring of life, assimilation, relationships, quality of life, sharing, happiness, growth were extracted. Third, the main channel for Korean language teaching in terms of lifelong education turned out to be online based and its approach was being developed in two separate branches, Korean language learning in general and Korean teacher training. Lastly, conclusions were drawn that the Korean language teaching materials should be closely associated with the learners’ life, all in terms of temporal and spatial aspects, as well as individual and social contexts.

This article first acknowledges the undeniable growth and success of the Korean textbook studies but emphasizes at the same time, the need to explore new perspectives and methodologies. It particularly focused on how and to what extent the learners of Korean, or the latent protagonists of the texts, would relate and sympathize with the course books about their feelings and circumstances. Qualitative analysis of the texts in the course books based on the well-known counseling techniques revealed a few issues. Advised by the counseling experts, in-depth survey is then conducted to categorize relevant counseling techniques that can be implemented in the textbooks. In sequence, we present an actual case of the course materials in which the relevant counseling techniques are applied. Five counseling techniques that were proposed in this article proved their merits and effectiveness of gaining new perspectives on the Korean textbooks. This study did not seek for a general principle which can be applied in all the textbooks nor a theoretical criticism. Its point is in that the long neglected extralinguistic aspects, such as counseling, advising and expressing feelings are brought forward and dealt in regards to their methodological application in the textbooks.

The objective of language education and learning lies not only in the transfer of knowledge but also in the encouragement of efficient communication. Consequently, the comprehension of the colloquial expressions and idioms used within a specific genre of the target language as well as the development of skills to utilize them, are important. From such perspective, this study focuses on how the frequently appearing sentence structure of ‘-ㄹ 수 있다’, which is a form of a formulaic expression within an academic text, plays a significant role as a hedge, and that this expression within KAP education have substantial value to be proposed as an express pattern. Firstly in this study, the value of the hedge expressions value within academic text was verified and amongst it, the background to why attention must be placed on the ‘-ㄹ 수 있다’ expression. Moreover, by examining ‘-ㄹ 수 있다’ as a frequently used formulaic expression, it was made the theoretical background of this study. In the subsequent chapter 4, the characteristics of ‘-ㄹ 수 있다’ sentence structure was contemplated. Furthermore, it was elicited that the ‘-ㄹ 수 있다’ sentence structure not only displays a not-strong behavioral stance of the writer through delivering the proposition in the form of quotational phrase or noun phrases but also that the meaning is discriminated minutely following the choice of the sentence structure used precedently, even under same propositions. In chapter 5, the express patterns, centering on the frequent predicates of the ‘-ㄹ 수 있다’ expression, were comprehensively organized. Through this, it was made so that the outcome of this study could be used for KAP education as baseline data.
