Product Line Engineering(PLE) is a software reuse paradigm that core assets are defined using common features in a domain and are instantiated in various applications. To apply the core asset effectively, variants which satisfy application requirements are extracted and the core asset should be also instantiated based on the variants. For the work, variability on architecture and components should be extracted exactly and an instantiation process and guidelines should be defined based on this variability In this paper, we define variability types depending on core assets elements and describe artifact templates related to tile variability. We also propose a systematic process which uses defined core assets including variability and verify practicability of the proposed process and variability expression through doing ease study. If utilizing with the proposed process in PLE, it can be feasible to model concrete core asset and variability and to utilize practical application engineering.

ebXML(Electronic Business using extensible Markup Language) is an XML based new international standard framework of the electronic business. Interoperability among mutually different industry fields can be realized by reusing core component, as a infrastructure of data. For this interoperability, it is needed to define the concrete concept of core component, through analyzing the role and applicability of the core component in business process which defines the interoperability among different companies. Therefore, in this paper, we Inquire the role of the core component in the ebXML, and implement the core component storage system which generates core component to register in registry/repository. The designed system for storing the core component generates suitable core component structure to register in registry/repositor), which can be used to generate new business information entity in a modeling step of business process.

Given a document, keyphrase extraction is to automatically extract words or phrases which topically represent the content of the document. In unsupervised keyphrase extraction approaches, candidate words or phrases are first extracted from the input document, and scores are calculated for keyphrase candidates, and final keyphrases are selected based on the scores. Regarding the computation of the scores of candidates in unsupervised keyphrase extraction, this study proposes a method of adjusting the scores of keyphrase candidates according to the types of keyphrase candidates: word-type or phrase-type. For this, type-token ratios of word-type and phrase-type candidates as well as information content of high-frequency word-type and phrase-type candidates are collected from the input document, and those values are employed in adjusting the scores of keyphrase candidates. In experiments using four keyphrase extraction evaluation datasets which were constructed for full-text articles in English, the proposed method performed better than a baseline method and comparison methods in three datasets.

This study aims to develop a core competency model for adult college students. For this purpose, the core competencies of adult college students were derived by analyzing domestic and foreign literature studies. And the Delphi survey was conducted for the validity of core competencies. The SPSS 18.0 program was used for analysis. As results of the analysis, there are 11 core competencies of adult college students derived: communication, problem-solving and meta, interpersonal, personal management and development, digital information literacy, major knowledge, citizenship, convergence, character, professional job, and global. The core competency model of adult college students was developed by assigning numbers from 01 to 11 based on the results of the Delphi survey. Core competencies of adult college students were organically linked, so the cultivation of one core competency affects other core competencies.

This study analyzed the characteristics of National Science Curricula in the UK, Australia, New Zealand, Canada, Singapore, and Korea with respect to core competencies. In the case of overseas countries, literature review on their curricula was conducted, and four common features were extracted: 'association of cross-curricular competencies with science-specific competencies', 'a combination of science contents and scientific practices', 'an emphasis on communication skills', and 'representation of an achievement level of competency'. In addition, the common core competencies of science education were 'critical thinking', 'creative thinking', 'problem solving', 'inquiry skills', 'communication skills', 'cultural literacy', 'ability to integrate discipline', 'application skills', and 'personal/social competency'. In relation to these features, this study also investigated Korean science teachers' perceptions of core competencies in science education. A survey was conducted on 135 teachers in elementary, middle, and high school in Korea. Teachers were not well aware of what core competencies are, and after introduction, they thought that they wanted to and needed to teach core competencies to their students. Teachers claimed that critical core competencies in science education are 'creative thinking', 'problem solving', and 'inquiry skills'. Teachers thought that core competencies-based science class would help develop students' scientific literacy and communication skills. However, they have difficulties in conducting core competencies-based science class because they are not familiar with how to conduct the class and they expect that it will take a long time to prepare such a class.

The purpose of this study was to investigate the effect of a peer evaluation method on the core fundamental nursing skills competency, learning attitude, critical thinking and self-leadership of graduating nursing students. A survey using a questionnaire was administered to 326 nursing students. The data was analyzed using SAS(ver. 9.8) and AMOS(ver.20.0) The results of peer evaluation showed that the fundamental nursing skills competency was 3.77(${\pm}.62$), the learning attitude was 3.17(${\pm}.47$), critical thinking was 3.44(${\pm}.41$) and self-leadership was 3.60(${\pm}.49$). Core fundamental nursing skills competency showed statistical differences based on gender, major satisfaction, practice satisfaction, pre-learning and satisfaction with the peer evaluation. Core fundamental nursing skills competency was positively correlated with learning attitude(r=.295, p<.001), critical thinking was positively correlated with core fundamental nursing skills competency(r=.384, p<.001) and learning attitude(r=.623, p<.001), and finally, self-leadership was positively correlated with core fundamental nursing skills competency(r=.353, p<.001), learning attitude(r=.529, p<.001) and critical thinking(r=.690, p<.001). The factors affecting fundamental nursing skills competency were critical thinking and self-leadership. Core fundamental practical education programs to improve learning attitude, critical thinking and self-leadership need to be developed to increase core fundamental nursing skills.

본 논문에서는 핵심어 검출의 성능을 향상시키기 위한 새로운 후처리 방법을 제안한다. 일반적으로 핵심어 검출 시스템에 의해 검출된 상위 n개의 후보 단어들의 우도(likelihood)는 비슷한 경우가 많다. 따라서, 한 음성구간에 대해 음향학적으로 유사한 핵심어들간의 오인식 가능성이 높아진다. 그러나 기존의 핵심어 검출에 사용된 후처리 방법은 음성의 모든 구간에 같은 비중을 두고 우도를 평가하므로 비슷한 음향학적 특징을 가지는 유사한 핵심어들의 비교에 적합하지 못하다. 이를 해결하기 위하여, 본 논문에서는 후보단어들의 부분적인 음향학적 특징 차이에 기반한 가중치를 우도 계산 시에 반영함으로써 보다 변별력을 높이는 알고리즘을 제안한다. 실험 결과, 제안된 방법을 이용하여 유사한 후보단어들간의 변별력을 높일 수 있었고, 인식율이 93%일 때, 우도비검사 방법에 비해 19.6%의 false alarm rate을 감소시킬 수 있었다.
