본 논문에서는 구축함의 대공방어분야에 대한 업무를 IDEF0기능 모델링 방법을 통해 체계적으로 분석하였으며 미국방성의 산하기구인 DARPA에서 연구한 CPOF(Command Post Of Future) 의사결정 모델을 토대로 구축함의 대공방어분야에서 상황평가 단계에 대한 의사결정 과정을 심도 깊게 분석하였다. 또한 구축함의 대공방어분야에서 분석된 업무수행 절차를 토대로 상황평가 단계에서 의사결정과정에 따른 필요한 규칙집합을 식별하고 규칙집합 내부의 규칙들을 효과적으로 추출하기 위하여 규칙집합들에 대한 정의, 규칙에 입력되는 데이터, 규칙집합의 결과값, 규칙집합간의 상호관계를 분석하였다. 이러한 도메인 지식개발은 장차 해군 전투체계 지원용 전문가시스템을 개발하는데 중요한 기회기반이 될 것이다.

임상 및 실험 결과를 대외적으로 공인 받기 위해서는 통계적 검정 절차를 거치는 것이 일반적이다. 하지만 통계적 전문 지식이 부족한 사용자가 통계 소프트웨어를 배우는 데는 시간이 많이 걸리며, 결과 해석에도 어려움이 많은 실정이다. 데이터의 특성과 성질에 맞추어 통계법이 선택되어야 하는데, 통계지식이 부족한 초보자들은 가장 일반적인 분석법을 적용시키곤 한다. 이와 같은 방식의 통계분석은 잘못된 결과로 이어질 수 있기 때문에 올바른 분석법을 가이드 해주는 기능이 필요하다. 또한 통계분석법의 적합성을 평가하는데 있어 오차와 잔차의 등분산성 가정이 유용하게 쓰여질 수 있다. 본 연구에서는 사용자에게 올바른 분석법을 제시하는 비쥬얼 가이드 인터페이스와 잔차를 3D Glyph를 이용하여 보여주는 불확실성 시각화 방법을 사용하였다. 분석법 적용에서 나타나는 불확실한 데이터의 시각화는 의사결정에 도움을 줄 수 있다.

인터넷의 사용이 보편화됨에 따라 빠르게 변화하는 사용자의 요구를 만족시킴과 동시에 편리하고 유용한 서비스를 제공하기 위하여 사용자와 자연스럽게 의사소통할 수 있는 대화형 에이전트의 연구가 활발히 진행되고 있다. 그러나 현재 상용되고 있는 대부분의 대화형 에이전트들은 도메인 제한적 정보만을 제공하는 경향이 있어 도메인 변경의 경우 스크립트에서부터 새롭게 설계해야 하는 이중 부담을 겪고 있다. 본 논문에서는 스크립트 설계자가 특별한 사전 지식 없이도 간단한 입력 절차만 거쳐 자동으로 스크립트를 재구성할 수 있는 스크립트 인터페이스 구현에 초점을 맞춘다. 이 때 자연어로 입력되는 사용자 질의의 다양한 어휘들을 자동으로 대표 언어로 변환시킬 수 있도록 온톨로지 개념을 도입하여 동의어 사전을 구축함으로써 시스템의 효율성을 극대화한다. 또한 질의에 대한 다양한 답변 생성을 가능하게 하며, 실제 의류 사이트를 안내하는 대화형 에이전트를 구현하여 적용해 봄으로써 그 가능성을 알아본다.

It is a story through which people share their ideas and express their thoughts. Storytelling is temporally and spatially interconnected narration that consists of characters, background, its beginning and its conclusion. Furthermore, the story in storytelling is a means of delivering culture and history; thanks to the development of various media, delivering and exchanging the story are conducted in a variety of forms. Due to the technological advancement, the way storytelling is done has changed, which was a method called digital storytelling. This storytelling has been frequently used in education; that is, teachers utilize stories to communicate their thoughts. As receivers, students understand a shade of meaning and the role of language, thus reorganizing the important factors in the context of meaningful events. However, in practice the classes are so teacher-centered that the role of students are relegated to that of passive learners, thus debilitating the interaction between participants; as a result, this situation shows serious limitations in that it does not improve students' practical skills. Despite this situation, home economics has attempted to broaden students' practical knowledge and has enabled them to acquire procedural knowledge as its main objectives in the context of the entire life. To overcome this problem, this study attempts to demonstrate the lesson model utilizing the storytelling where the lively participation in the process and results of learning can increase learners' self-confidence and responsibility. This lesson model is believed to facilitate the communication among participants including teachers and students. Through this alternative teaching method, learners can participate in the process of learning so that they can acquire practical knowledge: this method can be a step-stone for further development. In conclusion, the development of curriculum and lesson plans should be encouraged.

This paper's research objective is to test educational content with different dimensions of knowledge during a graphic basic design course, while also proposing teaching plans and opinions for courses in flipped classrooms as well as enhancing educational efficiency. It categorizes educational content of courses based on the dimensions of knowledge in the learning objectives of Bloom's taxonomy. 120 students are divided into four experimental groups to respectively under go flipped classroom learning by using different dimensions of knowledge involved in course content. Course pretests and post tests are used to obtain and analyze experimental data. Among this knowledge, factual and conceptual knowledge obtained during extra curricular independent learning as well as programmed and meta-cognitive knowledge obtained during in-class learning from a flipped classroom can stimulate student's learning initiative and also enhance learning efficiency. According to research results and student feedback, this paper will propose targeted categorization methods for course content and also suggest educational strategies for these courses' flipped classroom model.

The police is huge career civil service organization. In 1999, police organization employed 7,801 persons as a new hiring. The police had revised employment system several times for competent human resources. But, it is true that much improvements need yet for person's employment which equip eligibility. Specially, discussions need for many new hirings by duty police system abrogation. Career civil service system is impossible of dismissal after permanent appointment. It is true that competitive rate of police officer examination much rose. But it's not important about organization development in addition this unconnects with competent resources. Must change police officer employment system for organization's future development. This study proposed policy about improvement way of examination for service step, field training officer and appointment.

Enterprise portal(EP) is the emerging service and technologies in recent business area. We divided the three subportal of EP - IPP(Information Processing Porta), DPP(Decisino Processing Portal) and EKP(Enterprise Knowledge Portal). IPP include the information processing area that conduct the general business field. DPP is the area that can support the employee's decision processing and making according to their roles. The function of EKP assist the tacit knowledge management and the collaboration job among knowledge workers. If we efficiently integrate and aggregate their subportal, our business information system can achieve more efficient and effective business performance. Also we can anticipate this model that serve the system environment, supporting the user friendly circumstance, enforcing e-business activity, connecting between customer and supplier, positioning more competitive advantage.

With the development of data-driven decision-making and sophisticated big data processing technique, there is a growing demand for information on how to process data. However, recent studies with data preprocessing mentioned only as a means to achieve a result. Therefore, in this study, we aimed to write in detail about the data processing pipeline, include preprocessing data. In particular, we shares the context and domain knowledge to aid fluent understand of the research.

This study was to develope and applicate the consumer education program with appropriate level for middle school students so that they could take systematic consumer education by using creative-discretionary activity. The procedure of this study was researching and analyzing the degree of learner's need and choosing the contents of education involved with the characteristics of adolescent consumers. This education program was performed at creative-discretionary activity class with the 3th grade of middle school. To evaluate the effect of education program, we compared with the difference of student's knowledge and attitude before and after this program was performed. Although there was no significant difference, student's knowledge and attitude was improved much better. And there marked a high satisfaction rate of 3.87 about the overall method of consumer education.

This study has analyzed the learning objectives in 6 Informatics textbooks that were published this year in the basis of 2009 revised curriculum using Anderson's taxonomy of Educational Objectives that was a revision of Bloom's taxonomy and Fuller's taxonomy that was presented for programming activities. Some dimensions of Anderson's taxonomy, such as conceptual and procedural knowledge, understand and apply in cognitive process are much more used in learning objectives in 6 Informatics textbooks. Interpreting and producing dimensions of taxonomy are well presented to balance in 6 Informatics textbooks by analysis of Fuller's taxonomy. This results will be a good case study in research about taxonomy of educational objectives and development of Informatics textbooks.
