This study was conducted to understand media and cultivate personality by using media as data for personality education. To achieve this purpose, the Personality Education Promotion Act and the Korea Educational Development Institute's personality virtues were selected as educational elements, and a personality education program using media was developed in combination with the middle school curriculum. For this study, first, in order to extract personality virtues, 13 personality virtues were finally selected as educational elements by comparing and synthesizing the personality virtues of the Personality Education Promotion Act and the Korea Education Development Institute. The final personality virtues selected are self-esteem, courage, sincerity, self-regulation, wisdom, consideration, communication, courtesy, social responsibility, cooperation, citizenship, justice, and respect for human rights. Second, in order to select media and set the direction of development of personality education programs, the process of collecting media data was confirmed, and the direction and goal of the program were set by analyzing the middle school curriculum. Third, in order to propose a method of applying a personality education program using media, the personality grafting unit was selected by referring to the commentary on all subjects of the 2015 revised curriculum.

At the time of operating and studying the subject special librarians of university libraries, an aim of this study is to seek the ways for the users to be aware and make the best use of them, and to receive the necessary assistance from them. To achieve this, I examined carefully the operation and management states, and surveyed and analyzed the actual users' awareness of these operations. Furthermore, I investigated the way to improve the required qualifications to be subject-special librarians and the users' awareness of them.

전자 메일은 매우 많은 사람들이 사용하는 편리하고 효율적인 통신 수단이다. 그러나 전자메일 주소를 쉽게 획득할 수 있다면 점을 악용하기 때문에 사용자가 원하지 않는 메일 즉 스팸 메일에 대한 문제가 심각해지고 있다. 이러한 스팸 메일을 자동으로 분류해주는 스팸 필터는 주로 영어를 대상으로 하고 있으며, 규칙 기반 필터링보다는 통계적 학습을 통한 필터링 방법을 주로 사용하고 있다. 본 논문에서는 베이즈 정리를 기반으로 하는 3가지 분류 알고리즘을 한글 전자메일을 대상으로 하여 스팸 메일 특히 음란성 메일을 분류하는데 있어 그 성능을 평가하고자 한다. 실험 결과, 단어의 스팸일 확률만을 이용하는 방법이 나이브 베이즈 알고리즘이나 m-estimate를 이용하는 방법보다는 성능이 우수함을 알 수 있었다 특히, 단어의 스팸일 확률만을 이용하는 방법은 false positive rate를 0%로 유지하면서도 다른 방법들보다는 필터링을 잘 해내고 있음을 확인할 수 있었다. 그리고, 자질 선정에서는 명사나 명사/형용사를 사용할 경우에 그 에러율이 가장 적었다.

The objective of this study is to identify performance factors in the automatic classification of records by utilizing metadata that contains the contextual information of records. For this study, we collected 97,064 records of original textual information from Korean central administrative agencies in 2022. Various classification algorithms, data selection methods, and feature extraction techniques are applied and compared with the intent to discern the optimal performance-inducing technique. The study results demonstrated that among classification algorithms, Random Forest displayed higher performance, and among feature extraction techniques, the TF method proved to be the most effective. The minimum data quantity of unit tasks had a minimal influence on performance, and the addition of features positively affected performance, while their removal had a discernible negative impact.

In this paper, we present an approach to sentence boundary detection for web documents that builds on statistical-based methods and uses rule-based correction. The proposed system uses the classification model learned offline using a training set of human-labeled web documents. The web documents have many word-spacing errors and frequently no punctuation mark that indicates the end of sentence boundary. As sentence boundary candidates, the proposed method considers every Ending Eomis as well as punctuation marks. We optimize engine performance by selecting the best feature, the best training data, and the best classification algorithm. For evaluation, we made two test sets; Set1 consisting of articles and blog documents and Set2 of web community documents. We use F-measure to compare results on a large variety of tasks, Detecting only periods as sentence boundary, our basis engine showed 96.5% in Set1 and 56.7% in Set2. We improved our basis engine by adapting features and the boundary search algorithm. For the final evaluation, we compared our adaptation engine with our basis engine in Set2. As a result, the adaptation engine obtained improvements over the basis engine by 39.6%. We proved the effectiveness of the proposed method in sentence boundary detection.

In Korea, the criteria for the requirements of a secondary school science teacher's certificate are based entirely on the subjects and/or areas as prescribed in laws for the teacher's licensure examination. However, the criteria do not account for the specific competencies or qualities that a good science teacher should possess. The objective of the research was to explore and suggest the three lists of the image of an ideal science teacher, science teacher's role and science teacher's competency that might be used to establish the criteria for science teachers' certificate and the curricular content for science teacher education in Korea. In order to achieve this objective, the study used such research methods as literature analysis, status survey in combination with on-line workshop, in-depth interview, and professional consultation. The participants in the research comprised of a group of 258 students (186 middle school students and 72 high school students) and 13 in-service science teachers (8 middle school science teachers, 5 high school science teachers) for questionnaire survey and on-line workshop, and 4 science teachers for in-depth interview. The list of the image of ideal science teacher, science teacher's role, science teacher's competency contains 44, 32, and 75 statements, respectively. Based on the results of the research, this paper suggested that the criteria for the Korean secondary school science teacher's certificate requirements be selected and organized in consideration of the teachers' competencies rather than the courses and/or subject areas. It is also implied in the paper that further research over a period of time is necessary for using the competencies for curricular contents and/or science teacher's certificate standards.

This study examined the nurse images perceived by nursing students. The study was specifically meant to determine what images grade 2 and 3 nursing students had about nurses before and after their clinical practice to define the nurse's image. The selected nursing students were interviewed to obtain their opinions on the definition and necessity of a nurse and what a great nurse should be like as well as their prejudice about nurses, and content analysis was carried out to categorize their statements. As a result, 48 significant statements and 14 categories were selected. The findings of the study might not be generalizable because the subjects in this study were selected by convenience sampling from two different nursing departments located in Gangwon Province and Gyeonggi Province. More concrete and reliable results are expected if more students from more geographic regions are investigated.
