자연어 추론 모델은 전제와 가설 사이의 의미 관계를 함의와 모순, 중립 세 가지로 판별한다. 영어에서는 RTE(recognizing textual entailment) 데이터셋과 다양한 NLI(Natural Language Inference) 데이터셋이 이러한 모델을 개발하고 평가하기 위한 벤치마크로 공개되어 있다. 본 연구는 국외의 텍스트 추론 데이터 주석 가이드라인 및 함의 데이터를 언어학적으로 분석한 결과와 함의 및 모순 관계에 대한 의미론적 연구의 토대 위에서 한국어 자연어 추론 벤치마크 데이터 구축 방법론을 탐구한다. 함의 및 모순 관계를 주석하기 위하여 각각의 의미 관계와 관련된 언어 현상을 정의하고 가설을 생성하는 방안에 대하여 제시하며 이를 바탕으로 실제 구축될 데이터의 형식과 주석 프로세스에 대해서도 논의한다.

The purpose of this paper is to provide values and effectiveness to libraries making a new social network service marketing model and strategy. According to study, when libraries entice library users with social network services, the users become loyal customers who give libraries long-term supports. For method of study, it establishes 15 hypotheses and proves those hypotheses with 157 responders. After inspecting hypotheses, 13 hypotheses are adopted and 3 hypotheses are dismissed. During the research, it is verified that usefulness perceived by library users is the most important factor of user satisfaction and continuous use intention which increased library users' intention to continue visiting the library. In addition, effectivness of marketing and cause are found in order of system quality, information quality, reliability, interactivity, subjective norms. In other words, the study found that library users found their information for using social network services and this attribute affects user satisfaction and ultimately continuous use intention in a positive way.

본 연구에서는 스마트 의류에 대하여 소비자들이 느끼는 지각된 가치가 소비자 수용도에 미치는 영향을 조사하고자 하였다. 이를 위해 MP3 기능 재킷과 심박 모니터링 스포츠웨어를 대상으로 소비자들의 수용도에 대한 연구모형을 수립하였고, 선행연구들을 근거로 각 구성요인 간의 관계에 대해 연구가설을 설정하였으며, 그 경로가설을 검증하였다. Davis(1989)가 제안한 TAM을 적용하여 스마트 의류의 수용과정을 설명한 결과 모형의 적합성을 검증하였으며, 8 개의 경로가설 중 6 개의 경로가 통계적으로 유의함이 밝혀져 채택되었다. 그 결과는, 첫째, 지각된 사용용이성은 유용성을 거쳐 태도에 간접적으로 영향을 주었고, 태도는 다시 수용의도에 영향을 주는 것으로 나타났다. 둘째, 지각된 유용성은 지각된 가치에 대한 태도에 영향을 주는 것으로 나타났으나, 스마트 의류의 수용의도에는 영향을 미치지 않는 것으로 분석되었다. 셋째, 지각된 가치가 스마트 의류에 대한 태도와 수용의도에 둘 다 영향을 미치는 것으로 나타났다. 넷째, 스마트 의류에 대한 태도는 구매의도에 영향을 미치는 것으로 나타났다.

In this study, I took the evidence-explanation (E-E) continuum perspective to examine the epistemological implications of scientific reasoning cases designed by preservice elementary teachers during their simulation teaching. The participants were four preservice teachers who conducted simulation instruction on the seasons and high/low air pressure and wind. The selected discourse episodes, which included cases of inductive, deductive, or abductive reasoning, were analyzed for their epistemological implications-specifically, the role played by the reasoning cases in the E-E continuum. The two preservice teachers conducting seasons classes used hypothetical-deductive reasoning when they identified evidence by comparing student-group data and tested a hypothesis by comparing the evidence with the hypothetical statement. However, they did not adopt explicit reasoning for creating the hypothesis or constructing a model from the evidence. The two preservice teachers conducting air pressure and wind classes applied inductive reasoning to find evidence by summarizing the student-group data and adopted linear logic-structured deductive reasoning to construct the final explanation. In teaching similar topics, the preservice teachers showed similar epistemic processes in their scientific reasoning cases. However, the epistemological implications of the instruction were not similar in terms of the E-E continuum. In addition, except in one case, the teachers were neither good at abductive reasoning for creating a hypothesis or an explanatory model, nor good at using reasoning to construct a model from the evidence. The E-E continuum helps in examining the epistemological implications of scientific reasoning and can be an alternative way of transmitting scientific reasoning.

The aim of this study was to look for the cause of shortage of K-League spectators from a consumer's perspective and to offer solutions. For this, we offered enhancement method of the K-League spectators through dual path model based on existing relative researches. The first path involved consumer reaction to external factors of the K-League game. This path explained relational view(=we-ness) of consumers on K-League game(Hypothesis 1, 2). The second path explained personal view on K-League game. This path means consumer reaction to K-League game itself(Hypothesis 3, 4). The empirical study was based on a field survey and structural equation model. The results showed that we-ness positively affected team loyalty(Hypothesis 1) and the team loyalty positively affected spectating intentions(Hypothesis 2). It also revealed that flow of K-League game positively affected consumer satisfaction(Hypothesis 3). Finally consumer satisfaction was found to affect spectating intentions(Hypothesis 4). The significance of present study is to extend scope of research which is related with cheerleading of sports game. And this study emphasize the importance of we-ness and flow in sports game.

The purpose of this study is to identify the influecing factors on the user's satisfaction and continued usage intention in IPTV services. For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 310 users who have used IPTV and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, perceived enjoyment was confirmed to have a positive effect on user's satisfaction and continued usage intention, however, we found no evidence of a statistically significant relationship between perceived enjoyment and perceived usefulness. Second, perceived ease of use was found to positve influence perceived usefulness, however, we found no evidence of a statistically significant influece on user's satisfaction. Third, confirmation was found to positively influence satisfaction and continued usage intention. Fourth, perceived usefulness had a positive influence on continued usage intention, and both perceived usefulness and satisfaction had a positive influence on continued usage intention. Based on these findings, we suggested the implications and further research directions.

Based on the Technology-Organization-Environment (TOE) model, this study proposed a research model that explains the continuance intention of users in the with Covid-19 era considering the technical, organizational, and environmental aspects of Remote Work Solution (RWS). To verify the research model and hypothesis, an online survey was conducted on domestic RWS users. Partial least squares (PLS) were utilized to analyze the collected 411 data. As a result of the analysis, it was found that functionality and security level had positive impacts on both productivity improvement and satisfaction. However, it was also confirmed that organizational readiness had a positive effect on productivity improvement but did not affect satisfaction. Furthermore, the results revealed that government support had a positive relationship with continuance intention, but the health concerns did not. Finally, the correlations between productivity improvement, satisfaction, and continuous intention were confirmed to be significant. Therefore, 9 out of a total of 11 hypotheses were supported.

본 논문에서는 음성과 자연언어의 통합처리를 위한 효과적인 병렬 계산 모델을 제안한다. 음소모델은 continuous HMM에 기반을 둔 문맥종속형 음소를 사용하며, 언어모델은 knowledge-based approach를 사용한다. 또한 계층구조의 지식베이스상에서 다수의 가설을 처리하기 위해 memory-based parsing기술을 사용하였다. 본 연구의 병렬 음성인식 알고리즘은 분산메모리 MIMD 구조의 다중 Transputer 시스템을 이용하여 구현되었다. 실험을 통하여 음성인식 과정에서 발생하는 speech-specific problem의 해를 제공하고 음성인식 시스템의 병렬화를 통하여 실시간 음성인식의 가능성을 보여준다.
