문서를 대표하는 단어를 추출하는 색인어 추출은 정보검색 시스템의 질을 좌우한다. 대부분의 색인어 추출 시스템은 명사를 추출하고 있으며, 가능한 모든 명사를 추출하고 있다. 이러한 방법은 불필요한 단어가 그 문장을 대표하는 색인어로 추출될 가능성이 높으며, 이는 정보 검색 시스템의 효율을 저하시킨다. 이를 해결하기 위해 품사 태깅이나 구문 해석 단계 등을 통해 불필요한 후보를 제거할 수 있지만, 태거를 구축하거나 구문 해석을 위해서는 많은 비용과 시간이 필요하다. 본 논문에서는 구문 형태소 단위의 형태소 해석에 기반한 색인어 추출 방법을 제안한다. 구문 형태소는 통사적/의미적으로 강한 공기 관계를 가지면서 문장에서 하나의 통사적 단위나 자질의 단위로 표현되기 때문에 구문 형태소내에 포함된 단어열들은 대부분 색인어가 될 수 없다. 이러한 방법을 이용하여, 형태소 해석 결과를 이용한 색인어 추출에서 발생하는 색인 오류를 제거함으로써 색인기의 성능을 높이는 방법을 제안한다.

본 논문에서 제안하는 구문분석기는 품사 태거를 사용하지 않고 문장에서 나오는 모든 형태소 분석 후보에 의존관계를 부여하는 광범위 의존구문분석기이다. 중의성이 발생할 수 있는 문장에 대해 나오는 모든 후보 구문분석 트리를 출력하며 규칙을 통해 순위화를 진행한다. 또한 문형 정보 말뭉치의 적절한 사용을 위해 이전 연구의 한계점을 극복한 규칙과 알고리즘을 구현하고 문형 정보를 통해 후보 구문분석 트리의 순위화를 강화하였다. 뿐만 아니라 순위화가 어려운 [명사-관형사구] 자질에 대해 문형 정보를 사용하여 순위화를 강화하였다. 그 결과, 1순위의 구문 분석 트리에 대한 UAS(Unlabeled Attachment Score)가 0.52% 향상되었고, 후보트리에 대한 평균 정답 순위는 12.2%의 성능향상을 보였다.

The purpose of this study is to investigate social distance and attitude toward migrants's citizenship in Korea, a society with increasing cultural diversity. Using data from the 'Multiculturalism and Social Integration Survey' conducted by Academy of Korean Studies in 2008, this study analyzes three main issues: social distance between Koreans and foreigners, perception of the bases of national identity, and attitude toward migrants' citizenship and the causal factors of the attitude. The results show that social distances between Koreans and African Blacks/Arabs are significantly larger than those between Koreans and other ethnic or racial groups. But the relatively large social distances between Koreans and South-East Asians/North Korean defectors poses a more serious challenge to Korean society, since South-East Asians and North Korean defectors have comprised ever bigger part of migrants in Korea. The civil element is found to be more important base of national identity than the cultural or the ethnic bases, and there exists a strong negative attitude toward dual nationality. The results of regression analysis suggest that the potential of global citizenship for migrants will be realized by expanding universalism for basic human rights and awareness of the civil base of national identity on the one hand, and by minimizing the strong belief in ethnic homogeneity and the negative attitude toward dual nationality on the other hand.

This paper aims to identify determinants of entrepreneurial intentions among college students of a university in Daejeon. We have used a revised Entrepreneurial Intention Questionnaire including personal traits, demographic characteristics, the three factors of the Theory of Planned Behavior (TPB), motivations to startup and planned startup time, and entrepreneurial intentions. The analysis shows that there are strongly significant and positive relationships between the three TPB factors and entrepreneurial intentions of college students. In addition, students' motivations to create a firm such as independence and self-achievement have a positive and significant effect on their entrepreneurial intentions, while the students who want to start their business right after their graduation have significantly higher entrepreneurial intentions than those who want to create a firm after doing a salaried job. Furthermore, students whose parents have created or operated a firm have no significant difference from others, and parents' startup business type are significantly different from their sons and daughters' interested areas of business.

Service industry performance and competitive advantage depend on the attitudes and behavior of customer service employees who produce and deliver services through contact with customers. Most studies on customer service employees so far have concentrated on kindness, attitudes, or benefits. This study focuses on the increasing importance of customer service employees and intends to study them from the viewpoint of human brands that recognize customer service employees as a brand. In addition to the role of the employee at the service contact point, the customer participation behavior affects the interaction process with the customer service employee. Ultimately, customers could no longer be excluded from control to improve service quality. This study based on theory that the human brand characteristics of the customer service employees lead the customer's participation, which has a positive effect on the relationship with the service brand and the service brand attitude surveyed and analyzed customers who use service brand. This study is summarized as follows. First, the relationship between the service brand and the customer is examined. Second, this study also expands prior studies by examining the human brand characteristics of customer service employees and customers' willingness to participate in providing information on the impact of the consumer-brand relationship. The results of the study indicate that among the customer service employees' human brand characteristics reliability, familiarity, and empathy were found to affect the relationship between customers, the service brand, and the attitude toward the service brand the most. This study provides important implications for theoretical and practical strategies by examining the qualities and characteristics of customer service employees, which are the most important agents of marketing.

This study examined the effect of preservice child care teacher's competency on career stress and the effect of career aspration as a mediayor in the relationship between teacher's competency and career stress. The survey based on self report questionnaires was administered to a total of 200 students in child education and care college in Gyeonggido areas. The results of this were as follow: First, the result which examined the correlationship between major variables has found to be the significant correlationship of preservice child care teacher's competency, career stress and career aspiration. Preservice child care teacher's competency and career aspiration have found to have significant positive correlation but career stress and Child care and education teacher's competency and career aspiration have found to have the negative correlationship. Second, the result which examined the mediated effect of career aspiration in the relationship between teacher's competency and career stress has found that career aspiration has the complete mediated effects. Consequently, the mediating effects of career aspiration were confirmed. Based on the above results in the study meanings. limitations and proposals for next studies in the study were discussed.

This study aimed to develop self-diagnosis tools to evaluate the common competence level of public library librarians, apply them to actual public library librarians, and analyze the factors of competency value evaluation through empirical research methods. To this end, the study modify the existing capacity value evaluation indicators of librarians from a public library perspective and conducted a survey to self-diagnose the common capabilities of public library librarians. As the results of analysis showed that librarians of public libraries themselves think that the level of core competence that professional librarians should acquire is relatively higher than the average. Among the overall capabilities of librarians, the average of the 'librarians' behavior and attitude' area was the highest, followed by the 'librarians' skill' and 'librarian's knowledge' areas. The study suggested to strengthen the capacity of public library librarians for various duties, the re-education system for librarians should be established, and a systematic system for promoting librarians' duties as professionals, and a personnel system for professional development.

한국어에서의 품사 결정 문제는 형태론적 중의성 문제도 있지만, 영어에는 발생하지 않는 동품사 중의성 문제로 더 까다롭다. 이러한 문제들은 어휘 문맥을 고려하지 않고서는 해결하기 어렵다. 통계 자료 부족 문제에 쉽게 대처하는 모델이 필요하며 문맥에 따른 품사를 결정하고자 할 때 서로 다른 형태의 여러 가지 어휘 문맥 정보를 반영할 수 있는 모델이 필요하다. 본 논문에서는 이런 점에 가장 적합한 최대 엔트로피(maximum entropy : ME) 모델을 품사태깅 작업에 이용하는 문제에 대해 다룬다. 어휘 문맥 정보를 이용하기 위한 자질함수가 매우 많아지는 문제에 대처하기 위해 필요에 따라 어휘 문맥 정보를 사전화 한다. 본 시스템의 특징으로는 어절 단위 품사 태깅을 위한 처리 기법. 어절의 형태소 분석열에 대한 어절 내부 확률 계산. ME 모델의 정규화 과정 생략에 의한 성능 향상, 디코딩 경로의 확장과 같은 점들이 있다. 실험을 통하여 본 연구의 기법이 높은 성능의 시스템을 달성할 수 있음을 알게 되었다.

The purpose of this study was to investigate the relationships among elementary school teachers' high school and college backgrounds in science, their attitudes toward teaching science, their science teaching efficacy beliefs, and their instructional strategies. Both quantitative and qualitative research methodologies, were utilized in this study. This paper, however, presents only the results of the quantitative data analysis while expecting to report the qualitative data analysis outcomes afterwards. Four instruments were used to ascertain information concerning teachers' backgrounds in science(the number of high school science courses they took and the grades of courses, the number of college science courses and grades, the number of college science methods courses and grades), attitudes toward teaching science, science teaching self-efficacy beliefs(personal science teaching efficacy and science teaching outcome expectancy), and their instructional strategies(indirect, direct, and mixed methods). A sample of 340 practicing elementary school teachers participated in this study. To determine statistically significant results, Pearson's correlation coefficient was used to relate teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs and their instructional strategies. The correlation coefficients were statistically significant regarding four variables, teachers' backgrounds in science, attitudes toward teaching science, science teaching self-efficacy beliefs, and instructional strategies investigated in this study. These results can be interpreted that programs of teacher preparations and trainings which include science and science methods courses should help prospective and practicing teachers change in their attitudes and beliefs toward science teaching. It is expected that future studies concerning teachers' attitudes, beliefs, and behaviors toward teaching science can help to improve science teacher education in Korea.
