이질성, 이동성, 가변성 등의 특징을 갖는 유비쿼터스 컴퓨팅 환경에서 사용자의 의도에 맞도록 자율적이고 동적인 서비스를 제공하기 위해서는, 실시간의 상황을 고려하여 목적 달성에 필요한 서비스들을 합성할 수 있는 기법과, 이를 가능케 하는 효과적인 서비스 기술 및 관리 방법이 전제되어야 한다. 본 연구에서는, 도메인 내의 서비스를 추출하여 서비스 온톨로지로 구조화하는 메커니즘을 제안한다. 추출된 서비스는 제안한 서비스 규격에 따라 기술되고 온톨로지 내에서 계층적인 구조를 이루게 된다. 이를 근간으로 사용자는 다양한 추상화 레벨의 서비스를 사용하여 목표를 기술할 수 있고, 서비스 오버로딩 기법을 통해 실행 시에 가장 적합한 서비스가 선택된다. 또한, 요청한 서비스가 유효하지 않은 경우에도 서비스 온톨로지를 참조하여 대체 서비스를 찾을 수 있는 합성 방법을 제안한다. 구축한 서비스 온톨로지에 대한 실험 결과, 비구 조화된 서비스 리스트를 사용하는 것보다, 서비스 온톨로지를 사용함으로써 사용자의 목적 달성 성공률을 높일 수 있을 뿐만 아니라 서비스의 바인딩 시간도 감소시킬 수 있음을 보였다. To provide autonomous and dynamic services for users in a ubiquitous environment where heterogeneity, mobility and variability are main characteristics, an efficient service description/structuring mechanism and a service composition method are essential. Service composition can consider context in real-time and compose appropriate services. In this research, we propose a mechanism for extracting services from a specific domain and structuring them into hierarchical service ontology. Each service is described using the proposed service specification. Based on this service ontology, users can represent their goals using various abstraction levels of services, and then our service overloading method enables to invoke the most appropriate service at the execution time. Moreover, we present a method which can discovery an alternative service by referencing the service ontology, when the requested service is not available. The experimental result shows that our service ontology could improve the success probability of users' goals and reduce service binding time compare to using just an unstructured list of services.

In recent years, various services in mobile environments due to the growth of mobile devices and related techniques like wireless networks. Furthermore, as the increasing communication traffic in cellular networks has become a new significant issue, many studies for device-to-device(D2D) communication and D2D-based cooperative services have been performed recently. In this paper, we design a smart agent system for D2D-based cooperative services and propose a dynamic service binding method based on service ontology. We classify roles of mobile devices for cooperative services by defining three types of smart agents, and construct a knowledge base in order to describe properties of ``service`` unit. The proposed knowledge model, D2D cooperative service ontology, can enable a autonomous cooperative services between mobile devices by binding a requested service to the appropriate member device according to the real-time context in mobile environments.

유비쿼터스 메타서비스 온톨로지 자동 생성을 위한 번역기 개발

To provide dynamic services for users in ubiquitous computing environments by considering context in real-time, in our previous work we proposed Metaservice concept, the description specification and the process for building a Metaservice library. However, our previous process generates separated models - UML, OWL, OWL-S based models - from each step, so it did not provide the established method for translation between models. Moreover, it premises aid of experts in various ontology languages, ontology editing tools and the proposed Metaservice specification. In this paper, we design the translation process from domain ontology in OWL to Metaservice Library in OWL-S and develop a visual tool in order to enable non-experts to generate consistent models and to construct a Metaservice library. The purpose of the Metaservice Library translation process is to maintain consistency in all models and to automatically generate OWL-S code for Metaservice library by integrating existing OWL model and Metaservice model.

본 논문에서는 질의 응답 시스템에서 정답 추출을 위해 사용되는 표층 텍스트 패턴을 장거리 의존 문제에도 적용 가능하도록 확장하는 방법을 제안한다. 기존의 패턴 추출 시스템들의 패턴을 구성하고 있는 단어들간의 연속성과 불연속성에 대한 정보를 나타내도록 패턴 형태를 확장함으로써 장거리 의존 문제를 해결한다. 본 논문에서 제안한 형태의 패턴을 TREC-10의 질의를 이용해서 웹 데이터로 실험하여 정확도와 TREC의 평가 기준인 MRR을 사용해서 기존 시스템들과 성능을 비교했다.

창의적 드라마를 활용한 <황조가> 교육방안 연구

이미연 ( Lee Mee-yeon ) 한국고전문학교육학회 2011 고전문학과 교육 Vol.22 No.-

The purpose of this study is to make use of educational drama to compose and practice creative teaching methods for students to experience the ancient literary works, unfamiliar and historically far away objects under the light of their real present lives. The creative dramas, which are prompt, non-performance, processoriented form of play, among various educational play teaching methods let the students enhance their language and communication skills, problem-solving capacity, creativity, positive self-esteem and potential to understand the art play by participating the drama activities. The use of creative drama in teaching the ancient literature enable students to meet the characters and perceive the events and backgrounds from diverse perspectives, which leads to holistic growth by their understanding the universal truth found in the works. This thesis is about how to make the teaching structures and arrange the real activities focusing on 1) narration restructuring process using the context of the background legends 2) internalization process of emotion by studying the characters in teaching Hwangjoga(the song of a nightingale). The students are led to study two possibilities of the poem, epic or lyric, and restructure the vacant part which historical fact cannot identify. These learning activities let students internalize the feeling and theme of the think of all the possibilities. We should try to ask and find the truth hidden between historical facts and literary imagination. It's the drama teaching that help to solve the problem. I hope that the teachers will be interested in teaching ancient poetry using drama activities during the class in order to experience the human life from various perspectives rather than staying the theoretical research and interpretation based on the historical research detached from real life.

〈해와 달이 된 오누이〉의 연극텍스트화 연구

이미연(Lee, Mee-Yeon),허승희(Huh, Sung-Hee) 한국문학회 2012 韓國文學論叢 Vol.62 No.-

〈해와 달이 된 오누이〉는 전 세계적으로 분포되어 있으며 수많은 구연자들에 의해 창의적으로 전승되어 온 텍스트이다. 이와 관련한 연구는 비교문학적, 신화적, 역사학적, 정신분석학적 관점 등에서 다양하게 진행되고 있다. 본 논문은 〈해와 달이 된 오누이〉의 연극텍스트화 과정을 다루고자 한다. 옛이야기의 연극텍스트화 과정은 이야기를 읽거나 듣는 차원에서 벗어나, 행동하고 표현하고 형상화하는 활동을 통해 입체적 차원으로 이야기를 경험하는 것이다. 극화 과정에서 이야기는 언어적, 비언어적 방법으로 다양하게 탐구되며 공연실행을 통해 무대화 과정을 밟을 수도 있다. 극적 기법은 그 모든 과정을 자연스럽게 연결하는 역할을 한다. 본 연구에서는 다양한 극적 기법을 활용하여 창의적 스토리텔링으로서 〈해와 달〉을 탐구하고자 하였다. 특히 〈해와 달〉의 현대적 변용을 통해 옛이야기가 가진 상징성을 풀어보고자 하였다. 호랑이, 어머니, 오누이를 중심으로 한 이야기의 서사구조가 현대와 만나는 지점에서 참여자들은 자신들이 처해있는 현실을 연극 속에 반영하였으며 실행 사례를 통해 참여자들이 자신의 삶과 이야기를 연결시키는 접점을 읽어낼 수 있다. 옛이야기의 연극텍스트화는 서사의 단순한 연극적 재연이나 모방이 아니라 연극을 통해 옛이야기를 구체적으로 ‘지금, 여기’에 현재화시킴으로써 이야기를 정서적으로 살아내는 효과를 지닌다. 따라서 참여자들은 옛이야기를 통해 내면과 외면의 통합을 이루어내며 그것은 개인적, 사회적 성장을 이루어낼 수 있는 계기가 된다. 〈The brother and sister who became the sun and moon〉 is one of the popular stories for storytellers who creatively demonstrate the anecdotes. Studies about the story have been handled by researchers in comparative literature, myth, history and psychology. This will describe how the story has been established as an important text for the followers. Being literalized and codified means that the listener would experience the story with the 3- dimensional mechanism like watching movie in an I-max movie theater. The process includes lingual or non-lingual way and conversion of the story to a play. The dramatic convention plays a role for bridging the gap between them. This will shed light on the way of writing and character analysis originated from the conflicts in between, of the story for creative storytelling with various dramatic conventions. In particular, the symbolism of the story will be told here as a more modern edition. The participants could experience the story as real as it gets at the point where the story meets the way of depiction about the main characters. Also the participants could read the tipping point for the virtual world and reality by having experiences of the characters of their own. Making the story in the play script is not just a re-write it or mimicking but creating and giving breathe to the story as an ‘experiencing now texts’. So the participants make solidification of in and outside of their own mind with the story and that will make a progress for the individual and the society.

This study examined the effect of work-family conflict on job involvement and job engagement. In addition, the moderating effect of self-leadership on the relationship of work-family conflict and job attitudes was also tested. In order to test the hypotheses, the survey was conducted for two months from August 2017 to September 2017 for the employees who are working in chinese firms. 400 questionnaires were distributed, in which 368 were obtained and 34 of them that are showing central tendency or inappropriate responses were excluded and 334 were finally analyzed by hierarchical multiple regression in SPSS ver.24. The findings indicate that the impact of work-family conflict on job involvement is positive and on job engagement negative. Self-leadership significantly moderated the relationship between work-family conflict and job engagement. However, the interaction effect between the role conflicts and Self-leadership on job involvement was not statistically significant.

In this paper, we propose an expansion method of surface text patterns which are used by Question-Answering systems to solve the long-distance dependency problem. We use additional information to present discontinuous patterns. Also, the cost of the system could be reduced by simplifying the training process. In this paper we implement the system based on the new training method to expand the form of patterns without external tools or knowledge bases. We prove that our system is efficient and reliable by comparing it with the performance of existing systems by the precision and MRR which is an evaluation method at TREC.
