As the dependence of technology on the economic structure increases, the importance of National Core Technology is increasing. However, due to the nature of the technology itself, it is difficult to determine the scope of the technology to be protected because the scope of the relation is abstract and information disclosure is limited due to the nature of the National Core Technology. To solve this problem, we propose the most appropriate literature type and method of analysis to distinguish important technologies related to National Core Technology. We conducted a pilot test to apply TF-IDF, and LDA topic modeling, two techniques of text mining analysis for big data analysis, to four types of literature (news, papers, reports, patents) collected with National Core Technology keywords in the field of Display industry. As a result, applying LDA theme modeling to patent data are highly relevant to National Core Technology. Important technologies related to the front and rear industries of displays, including OLEDs and microLEDs, were identified, and the results were visualized as networks to clarify the scope of important technologies associated with National Core Technology. Throughout this study, we have clarified the ambiguity of the scope of association of technologies and overcome the limited information disclosure characteristics of national core technologies.

Basic nursing core skills are the essential skills required of nurses to effectively care for their patients. This study introduces an on-campus practicum using a mobile-based reflective journal, and attempts identify the challenges faced by students when performing core clinical nursing skills. The on-campus practicum was operated based on Kolb's experiential learning cycle. For each class, students used mobile devices to write an online reflective journal. Analyzing contents of the reflective log helped in identifying difficulties experienced in executing core skills, and classifying them in terms of knowledge, skill, and attitude. The level of difficulty, importance, and confidence in the core clinical nursing skills were also assessed. Students were found to be struggling with various aspects of performing core nursing skills, especially in the skill category. Students also showed a lack of confidence in items they perceived as "high" difficulty, such as IV injection and indwelling catheterization. Moreover, over 50% students considered IV injection and vital sign checking as the most important core clinical nursing skills. Our data suggests the necessity to develop various contents and apply instructional strategies to solve the core skills difficulties faced by nursing students, and to continuously generate evidence for the same.

The purpose of this study is to examine the experiences and attitudes of elementary pre-service teachers, the level of entrepreneurship core competencies, and to analyze differences in entrepreneurship core competencies by grade, gender, and attitude. To this end, 208 elementary pre-service teachers who responded to the online questionnaire surveyed their experience, attitudes, perceptions, entrepreneurship attempts, and entrepreneurship core competency levels. As a result, pre-service teachers had a low level of understanding and direct participation in entrepreneurship education, the need for entrepreneurship education for elementary school students and teachers was high. The average of the value-creation competency group consisting of innovation, social value orientation, and change agility was relatively lower than the challenge, group creativity, and self-directed competency group. The difference of the entrepreneurship core competency level between the grades was not significant, and female students' competency levels were statistically significantly higher than male students. In addition, the average of the four core competencies of entrepreneurship in the group that recognizes the importance of entrepreneurship as essential competencies was statistically higher than that of their counterparts. Based on the results of this study, the implications for the design and development of a program for enhancing entrepreneurship competency for elementary school pre-service teachers were presented.

The two most influential rationales for the 21^st century science curriculum reform can be said to be core competence and scientific literacy. However, the relationship between the two has not been scrutinized but remained speculative - and this has made the harmonization of the general guideline and subject-matter curriculum difficult in Korean national curriculum system. This study compares the two discourses to derive implications for future science curriculum development. This study took a literature research approach. In chapter II, national curriculum or standards, position papers, and research articles were reviewed to delineate the historical development of the discourses. In chapter III and IV, the intersections of those two discourses are delineated. In chapter III, the commonalities of the two discourses are explicated with regard to crisis rhetoric, multi-faceted meanings (individual, community, and global aspects), organization of subject-matter content and teaching and learning method, and the role of high-stake exams. In chapter IV, their respective strengths and weaknesses are juxtaposed. In chapter V, it is suggested that understanding scientific literacy and core competence discourses to have a family resemblance as 21^st century science curriculum reform rationale, after Wittgenstein and Kuhn. Finally, the ways to resolve the conflict between the two ideas from the general guideline and subject-matter curriculum over crisis rhetoric were explored.

As of 2019, a report by the Ministry of Culture, Sports and Tourism showed that 884 diverse regional festivals are being held in the country. While there are successful festivals with large audience numbers and local economic effects, there are many festivals that only waste local budgets. Against this backdrop, the question of this study is "What are the key competences of a successful dance festival utilizing the VRIO model?" The development process and success factors of the success dance festival at home and abroad were analyzed in order to explore the key competences and specialization measures of the festival that our dance festival can take off as a successful dance festival. The purpose of the study is to examine what is the source of competitiveness of the regional festival through VRIO model, which can identify the key competencies of the festival to grow into a successful dance festival, and to derive the key competencies of the festival through the interview of the expert group(Focus Group Interview) to apply the development measures of our country's dance festival. According to the analysis, festival experts view the success factors of local festivals from various perspectives based on their empirical knowledge. The key competencies priority was 1. Theme, 2. the festival organization and professional personnel management, 3. The results came in the order of residents' participation. And the successful domestic and foreign dance festivals had their own core competencies. Growing up as a successful festival through festival management, which is worth no other festival, difficult to emulate, rare and difficult to replace, is seen as the biggest key to leading the regional festival to the world festival.

본 논문은 기계번역 시스템의 성능평가를 위한 '핵심어 전달율 측정' 방안에 대해서 기술한다. 기계번역 시스템의 성능평가는 두 가지 측면으로 고려될 수 있다. 첫 번째는 객관적인 평가로 IBM에서 주창한 BLEU score 측정이나 NIST의 NIST score 측정이 그 예이다. 객관적인 평가는 평가자의 주관적인 판단이나 언어적인 특성을 배제한 방법으로 프로그램을 통해 자동으로 fluency와 adequacy를 측정하여 성능을 평가한다. 다음은 주관적인 평가이다. 주관적인 평가는 평가자의 평가를 통해 번역의 품질을 평가하는 방법이다. 주관적 평가 방법의 대표적인 것으로는 NESPOLE이나 LDC가 있다. 주관적인 평가는 평가자의 정확한 판단으로 신뢰할만한 성능평가 결과를 도출하지만, 시간과 비용이 많이 들고, 재사용할 수 없다는 단점이 있다. 본 논문에서는 이러한 문제를 해결하기 위해, 번역대상 문장에서 핵심어를 추출하고, 그 핵심어가 기계번역 시스템의 수행결과에 전달된 정도를 자동으로 측정하는 새로운 평가방법인 '핵심어 전달율 측정' 방안을 제안한다. 이는 성능평가의 비용과 시간을 절약하고, 주관적 평가와 유사한 신뢰성 있는 평가결과를 얻을 수 있는 좋은 지표가 될 수 있을 것으로 기대한다.

In this paper, we propose a method for precision improvement based on core clusters and term proximity. The method is composed by three steps. The initial retrieval documents are clustered based on query term combination, which occurred in the document. Core clusters are selected by using proximity between query terms. Then, the documents in core clusters are reranked based on context information of query. On TREC AP test collection, experimental results in precision at the top documents(P@100) show that the proposed method improved 11.2% over the language model.

This paper deals with the effect of the internal sampling frequency and core band down sampling ratio on the overall performance of the MPEG USAC. Here, the internal sampling frequency is the sampling frequency of a signal actually coded. The core band down sampling ratio is the ratio of the width of the core band over that of the coded band. The performance was measured on 6 different test sound sources by the MUSHRA test with 10 subjects. The experiments showed that 1/3 or 1/4 core band down sampling ratio could yield the better performance than the conventional 1/2 ratio, especially at low rates.
