대화형 관계 추출의 목표는 주어진 대화에서 두 개체 간의 관계를 식별하는 것이다. 대화 중에 화자는 개체 및 관계와 관련이 있는 단서인 트리거를 통해 특정 개체 간 관계를 식별하는 것에 힌트를 얻을 수 있다. 그러나 데이터에 대해 항상 트리거 정보가 존재하는 것이 아니므로 트리거를 활용해 성능을 향상시키는 것은 어렵다. 본 논문은 이 문제점을 해소하기 위해 대화, 개체, 관계 중심으로 트리거 생성 모델을 학습하고, 이를 통해 생성된 트리거를 대화형 관계 추출에 학습하여 관계 식별에 효과적인 성능 향상을 보이는 접근법을 제안한다. 제안하는 접근법은 대화형 관계 추출 태스크에서 기존 성능과 비교한 결과 Dev, Test에서 각각 F1 19.74%p, F1 15.53%p 의 성능 향상을 보였다.

의학교육은 학생들에 대한 교육과 평가만으로 구성되지 않는다. 학생들이 그러한 교육을 모두 잘 이수하고 졸업할 수 있도록 잘 지도해 주는 것까지를 포함한다. 의학교육에 있어 이러한 지도가 필요한 이유는 의대생들의 학습과 생활에 문제가 자주 발생하기 때문이다. 이에 본 연구에서는 2005년도에 본 의과대학에서 이루어진 총104건의 상담사례를 분석하여 그 문제와 대안을 제시하였다. 나타난 문제로는 불완전한 교육과 극단적 내부경쟁, 학생들의 집단 학습적 행동, 시간 관리 및 학습방법의 문제, 불안과 우울의 문제, 열등감의 문제, 자기개발과 자기실현에서의 불안, 삶의 다양한 문제들과 가치관 형성의 어려움(이성교제, 가족관계, 학교 내 대인관계 등) 등이었다. 이에 대한 해결방안으로 다음과 같은 다섯 가지가 제안 되었다. 즉 학생들에 대한 "의대에서 공부하는 방법" 교육, 새로운 의대 학습 문화의 창출지원, 전공의 선발에 있어 다면적 평가 시스템의 도입, 상담을 담당해 주시는 교수들과 멘토(mentor)의 필요, 가치관 지향적인 의학교육의 필요이다.

최근 비전통적 성인 학습자가 새로운 입학자원으로 주목받고 있으며, 그중에서도 만학도의 대학 진학률은 급격히 상승하는 추세다. 이에 따라 이들이 대학생활을 무사히 마칠 수 있도록, 즉 학업중단이 발생하지 않도록 대학에서는 다양한 측면에서 방안을 골몰해야 하는 상황이다. 본 연구는 이러한 문제의식에 기반하여, 비전통적 학습자의 학업중단을 저지할 방안을 창업지원 측면에서 살펴보고자 하였다. 이는 학업능력, 성별, 교우관계 등을 중점적으로 살펴보는 기존 연구에서 더 나아가 창업지원이라는 새로운 요인과의 관계성을 만학도의 입장에서 심층적으로 살펴봄으로써 연구의 차별성을 강조한다. 본 연구는 대학 입학 이후 학교의 창업지원을 받은 경험이 있는 만 30세 이상의 만학도 총 10명을 대상으로 심층인터뷰를 진행하여, 학교의 창업지원이 학업중단을 저지하는 데 영향을 주었는지를 살펴보고자 한다. 또한 그 과정에서 이들이 느낀 감정과 태도, 가치 등을 근거이론을 통해 분석하여 학업중단을 저지할 방안을 모색하고자 한다. 만학도는 전통적 학습자와 달리 졸업 이후 인생2모작을 준비하는 경우가 상당수기에, 이들의 니즈를 명확하게 파악하는 일은 시대적 흐름을 반영한 기초연구로서 학교의 정책적 대안을 마련하기 위한 기반이 될 수 있다.

The purpose of this study is to explore the relationship between motivational belief about learning science, self-directed learning ability and conceptual understanding of matter change with a quantitative method, assuming that motivational belief and self-directed learning ability might affect conceptual understanding. To do this, the authors investigated middle school students' motivational belief about learning science, self-directed learning ability, and conceptual understanding of matter change using measurement tools based on previous studies, and then analysed the casual relationship between three variables using PLS structural equation model. As a result, three latent variables in this study could be evaluated as appropriated in reliability and validity. And also, self-directed learning ability could affect both the motivational belief and conceptual understanding, while motivational belief could affect only self-directed learning ability but not conceptual understanding. Through this study the authors confirmed that in the context of science learning self-directed learning ability can directly affect conceptual understanding but motivational belief can affect indirectly. This study is significant in that the causal relationship between different variables in science learning could be confirmed in a quantitate manner, and also in that it can suggest PLS structural equation method as a new research methodology in science education research area.

The objective of this study was to investigate the effect of an education method applying the flipped learning technique for college students. Both self-directed learning readiness and educational performance before and after applying the flipped learning were examined. After applying the flipped learning technique, teacher-student interaction, learning satisfaction, and learning motivation were identified. The correlation of each variable was examined after applying the flipped learning technique to investigate its influence on learning motivation. A total of 68 second-year nursing students enrolled in E University were analyzed. A difference between before and after applying the flipped learning was analyzed by the paired t-test; a correlation between the variables was analyzed via Pearson's correlation coefficient; and an influence on the dependent variable learning motivation was analyzed using the stepwise multiple regression analysis. The results showed that self-directed learning readiness increased before and after applying the flipped learning technique with statistical significance, and the difference of educational performance was not significant. After an education session applying the flipped learning technique, a learning motivation demonstrated a significantly positive correlation with self-directed learning readiness (r=0.33, p=.006), college student educational performance (r=0.51, p<.001), teacher-student interaction (r=0.72, p<.001), and learning satisfaction (r=0.79, p<.001). A significantly positive correlation was also observed between the other variables. Factors influencing learning motivation were learning satisfaction and teacher-student interaction. The explanatory power for learning motivation in the regression model considering these two variables was 71.3% (F=80.66, p<.001). Therefore, to enhance learning motivation in applying the flipped learning technique, it is necessary to increase learning satisfaction and to establish a strategy that further vitalizes the teacher-student interaction.

This study aimed to examine relationships between founders' entrepreneurial leadership, team learning behavior, team boundary spanning, and perceived performance in early-stage startups. The following results were recorded: (i) the indirect effects of entrepreneurial leadership on perceived performance via team learning behavior were statistically significant (β=.309, p<.05). (ii) relationships between team learning behavior and perceived performance were strengthened by team boundary spanning behavior (β=.259, p<.05). In this study, three practical implications are provided as follows: (i) startups need to seek team learning readiness and external learning stimulus to facilitate generative and transformative team learning; (ii) accelerators need to develop an entrepreneurial leadership program for founders; and (iii) startups need to explore external information by interacting with investors, R&D institutions, and other startups to strengthen the impact of team learning behavior on performance. Furthermore, two directions for future research are suggested as follows: (i) future researchers need to test causal relationships between entrepreneurial leadership and team learning behavior based on a newly designed time-series measurement plan; (ii) the actual effects of entrepreneurial leadership, team learning behavior and team boundary spanning on financial performance need to be tested two or three years later when the financial performance of early-stage startups usually becomes evident.

Entrepreneurs should continuously invest resource and capital for a long time to get tangible business results. In order to be successful, despite difficulties, it is essential for entrepreneurs to continue entrepreneurial businesses without giving up too early. Thus, it can be said that organizational commitment of entrepreneurs is essential for success. According to previous studies, the organizational commitment of entrepreneurs has a significant effect on organizing, establishments of new firms and new product developments. The purpose of this article is to examine the relationships among learning orientation, innovativeness and organizational commitment of entrepreneurs. Especially, we focus on the mediating effect of innovativeness in the relationship between learning orientation and organizational commitment and the moderating effect of career relevance among the relationships. Based on empirical analysis, we reported the following results. First, learning orientation, innovativeness and career relevance of entrepreneurs had significant positive effects on organizational commitment. Second, it was found that innovativeness of entrepreneurs has a partial mediating effect on the relationship between learning orientation and organizational commitment. Third, using Baron & Kenny's hierarchical multiple regression analysis, we examined the moderating effect of career relevance among the relationships of learning orientation, innovativeness and organizational commitment. Third, because the interaction term was found to be positively significant, it was concluded there is a moderating effect of career relevance between learning orientation and innovativeness. This means, when career relevance was higher than average, the influence of learning orientation on innovation increases even more. Fourth, it was also found there is a moderating effect of career relevance between learning orientation and organizational commitment. However, the results of the mediated moderating effect analysis showed the moderating effect of career relevance between learning orientation and organization commitment is an indirect effect of moderating effect of career relevance between learning orientation and innovativeness mediated by innovativeness.

The purpose of this study is to analyze the long term mediating effects of Self-regulated Learning(SRL) in the Relationships among the Perceptions of Middle School Students on the Democratic Attitude of Parenting(DAP) and their Relationships with Teachers(RT), and their Self-esteem(SE). The data sources were from the first (2010) and the third (2012) Korean Children & Youth Panel Survey(KCYPS). As a result, first, the perceived DAP had significant effects on the students' SE both directly and indirectly through SRL. Second, the perception on RT had indirect effects on their SE mediated by SRL. Third, this pattern in first year continued in two-year-later-SE. This study implies that DAP, RT, and SRL play important roles in the continuous development of adolescents' self-esteem.

This paper introduces a relation extraction system that can be used in identifying and classifying semantic relations between biomedical entities in scientific texts using machine learning methods such as Support Vector Machines (SVM). The suggested system includes many useful functions capable of extracting various linguistic features from sentences having a pair of biomedical entities and applying them into training relation extraction models for maximizing their performance. Three globally representative collections in biomedical domains were used in the experiments which demonstrate its superiority in various biomedical domains. As a result, it is most likely that the intensive experimental study conducted in this paper will provide meaningful foundations for research on bio-text analysis based on machine learning.
