인간의 언어지식은 다양한 개념 관계를 가지며 서로 망(network)의 모습으로 연결되어 있다. 인간의 언어지식의 산물 중에서 가장 체계적이며 구조적으로 언어의 모습을 드러내고 있는 결과물이 사전이라고 할 수 있다. 본 논문에서는 이러한 사전 뜻풀이 말에서 개념 어휘와 자동적인 지식획득을 통하여 의미 정보를 구조적으로 추출한다. 이러한 의미 정보가 추출되면서 동시에 자동적으로 개념 어휘의 의미 참조 모형이 구축된다. 이러한 것은 사전이 표제어 리스트와 표제어를 기술하는 뜻풀이말로 이루어진 구조의 특성상 가능하다. 먼저 172,000여 개의 사전 뜻풀이말을 대상으로 품사 태그와 의미 태그가 부여된 코퍼스에서 의미 정보를 추출하는데, 의미분별이 처리 된 결과물을 대상으로 하기 때문에 의미 중의성은 고려하지 않아도 된다. 추출된 의미 정보를 대상으로 정제 작업을 거쳐 정보이론의 상호 정보량(Ml)을 이용하여 개념 어휘와 의미 정보간에 연관도를 측정한 후, 개념 어휘간의 유사도(SMC)를 구하여 지식표현의 하나로 연관망을 구축한다.

This paper presents an efficient determination method of thematic roles from syntactic relations using rules and statistical model in Korean language processing. This process is one of the main core of semantic analysis and an important issue to be solved in natural language processing. It is problematic to describe rules for determining thematic roles by only using general linguistic knowledge and experience, since the final result may be different according to the subjective views of researchers, and it is impossible to construct rules to cover all cases. However, our hybrid method is objective and efficient by considering large corpora, which contain practical usages of Korean language, and case frames in the Sejong Electronic Lexicon of Korean, which is being developed by dozens of Korean linguistic researchers. To determine thematic roles more correctly, our system uses syntactic relations, semantic classes, morpheme information, position of double subject. Especially by using semantic classes, we can increase the applicability of our system.

The present study aimed at investigating how those students who retook college entrance examination(or RCEE) appreciate the experience. For this purpose, three persons from each cell at the 2(satisfaction with college life: high vs. low) by 2 (evaluation of RCEE: positive vs. negative) combination among those who participated in Lee and Jung study (2014) were selected and were interviewed. Qualitative data analysis based on phenomenological approach produced seven categories and 19 subcategories, which were grouped on the temporal dimension. First, when they were at the midst of this RCEE experience, the college students saw this as adversity that should be overcome while they underwent a limit of pain they could bear. Second, the college students evaluated this experience as upgrading my life with wound left unseen. Finally, they assigned to both of the positive and negative aspects of RCEE experience the meaning that the experience made them accept themselves as they were. Given these results, implications, limitations of this study were discussed.

Media consumers in the context of the Internet and digital media are using the same content to a variety of platforms. As such, the content of various genres is converted to the form of a new content through the process of fusion, combination, transformation, differentiation, reproduction, etc on the basis of digital media. That is referred to as trans-media. In order to create the successful content in trans-media era, it requires the work of Edi-curation. Edi-curation work is the act of editing and adding meaning to the curation work of curators. In that sense, this paper analyzed the definition and meaning for Edi-curation of publishing and comic(webtoon) content in trans-media era. Edi-curation process induces the changing role of consumers and producers of content in the digital media experience. In process of Edi-curation, consumers(producers) will soon lead to a media producer(consumer), namely proconsumer / produser. Diversification of digital platforms and devices, digital 1 person (or SNS) appeared in the media, etc. are also required to Edi-curation of content and comic(webtoon) published in a variety of ways. Depending on the intention of media producers (or consumers), content through the process of replication, montage, disassembly, dismantling, hypertext, compression, and reconstruction births to new content. The work of Edi-curation has the significance that it affects the way the media producers work in creative process, as well as the reading content of the media consumers. In the publishing content, Edi-curation work is the logicality destruction of a chapter or a paragraph, a sentence of colloquialisms, card news, the deformation of the utilization of video and media content. Meanwhile in the comic(webtoon) content, we mention the destruction of cut(frame), the various modifications of speech bubbles, onomatopoeia, and mimetic word.

As a certain job is repeatedly done by a worker, the outcome comparative to the effort to complete the job gets more remarkable. The outcome may be the time required and fraction defective. This phenomenon is referred to a learning-curve effect. We focus on the parametric modeling of the learning-curve effects on count data using a logistic cumulative distribution function and some probability mass functions such as a Poisson and negative binomial. We conduct various simulation scenarios to clarify the characteristics of the proposed model. We also consider a real application to compare the two discrete-type distribution functions.

Objective : This study was designed to analyze the concepts of current use and meaningful activity in the elderly and provide basic data on establishing concept of participation in meaningful activity and clinical applications. Methods : Using RISS, Google Scholar, Published and DBpia databases, the literature published in the journal was collected from January 2010 to July 2019. The main search term used was "meaningful activity" and 10 of the 182 papers were finally selected for analysis. Based on the qualitative level assessment study by Arbesman, Scheer and Lieberman (2008), the selected paper were classified as Level I to Level V. Results : Five out of 10 studies were published within the last 5 years, indicating that meaningful activity-related studies have been conducted recently. Through prior studies, the concept of meaningful activities was summarized as those that enable individuals to realize their values, achieve their goals and experience positive emotions in their daily lives. Conclusion : The concepts and direction of assessment tools derived from this study will be the basis for the study of 'meaningful activity participation' as a solution to the aging society's elderly problems in the future.

현재 사용되고 있는 작업방식은 로봇과 positioner의 상대적인 위치 및 자세설정에 의하여 작업효율 및 성능향상을 꾀할 수 있음에도 불구하고 비효율적인 방법으로 사용하고 있는 실정이다. 이러한 문제점을 해결하기 위한 방법중의 하나로 로보트와 positioner시스템을 하나의 기구학적 모델로 제어하는 방법이 제시된 바 있다. 상기의 연구에서는 로보트와 positioner(이하 R-P 시스템)간의 협조 제어가 여유자유도제어 방법을 이용하여 가능한 것임을 보였다. 그러나 용접작업과 같은 positioner 위에서의 연속경로 작업에 있어서는 작업공간과 특이성(singularity) 등에 관련된 여러 가지 문제점을 안고 있다. 특이성은 외부의 물리적인 제약이나 로보트의 기하학적 구조의 문제로 발생될 수도 있는데 이때 자유도의 손실을 유발하므로 임의의 원하는 방향으로 움직일 수 없게 된다. 이러한 면에서 R-P 시스템의 조작 성능 평가가 중요한 의미를 갖는다. 본 연구에서는 실제 산업현장에서 이용되고 있는 5 자유도를 갖는 수직 다관절형 로보트와 positioner에 대하여 협조 제어 방법을 검토한다. 그리고 작업공간 내의 조작성능평가를 위하여 Jacobian 행렬을 이용한 조작성지수를 위하여 Jacobian 행렬을 이용한 조작성지수를 도입하고 주어진 작업단면에 대한 이들의 분포를 등고선 그래프로 시각화 한다. 또한 조작성지수를 최대화 하는 알고리즘을 R-P 시스템에 적용하고 시뮬레이션을 통하여 그 타당성을 검토한다

Objective : This study implemented occupation-based practice as a group program for children with neurodevelopmental disabilities, and investigated the quality of occupational performance, performance and satisfaction, and efficacy levels of the program. Methods : ADOC-S(Aid for Decision making in Occupation Choice-School) and COPM(Canadian Occupational Performance Measure) were used to establish common meaningful occupational goals for 10 children with neurodevelopmental disabilities. After occupational analysis of the 'subway use', the Performance Quality Rating Scale(PQRS) were used to evaluate the quality of occupational performance. Occupation-based interventions were implemented by participants individually performing meaningful occupations in the most natural and real-life environments as possible. The trial consisted of 1 session of pre-intervention assessments, 8 sessions of intervention, where a single session of 100 minutes is provided once a week. Post-intervention evaluation was conducted over one session. Results : The quality of occupational performance by PQRS was 38.10 higher than before intervention. The occupation-based intervention as a group program used the maintain and modify(compensation, adaptation) approaches and acquisition model. In the early stages of intervention (1 to 4 sessions), the occupational performance was greatly improved. The performance level of COPM increased by 5.80 and the satisfaction level was increased by 7.00. In addition, high scores were found in program satisfaction through parental interview. Conclusion : The results of implementing occupation-based interventions to children with neurodevelopmental disabilities showed increase in quality of occupational performance, performance, and satisfaction along with positive effects of satisfaction levels for the program.

한국어 의미역 결정(Semantic Role Labeling)은 주로 기계 학습에 의해 이루어지며 많은 말뭉치 자원을 필요로 한다. 그러나 한국어 의미역 결정 시스템에서 사용되는 Korean PropBank는 의미역 부착 말뭉치와 동사 격틀이 영어 PropBank의 1/8 수준에 불과하다. 따라서 본 논문에서는 한국어 의미역 결정 시스템을 위해 의미역 부착 말뭉치와 동사 격틀을 확장하여 Korean PropBank를 확장 시키고자 한다. 의미역 부착 말뭉치를 만드는 일은 많은 자원과 시간이 소비되는 작업이다. 본 논문에서는 도메인 적응 기술을 적용해보고 기존의 학습 데이터를 활용하여, 적은 양의 새로운 학습 말뭉치만을 가지고 성능 하락을 최소화 할 수 있는지 실험을 통해 알아보고자 한다.
