The goal of text categorization is to classify documents into a certain number of pre-defined categories. The previous studies in this area have used a large number of labeled training documents for supervised learning. One problem is that it is difficult to create the labeled training documents. While it is easy to collect the unlabeled documents, it is not so easy to manually categorize them for creating training documents. In this paper, we propose a new text categorization method based on semi-supervised learning. The proposed method uses only unlabeled documents and keywords of each category, and it automatically constructs training data from them. Then a text classifier learns with them and classifies text documents. The proposed method shows a similar degree of performance, compared with the traditional supervised teaming methods. Therefore, this method can be used in the areas where low-cost text categorization is needed. It can also be used for creating labeled training documents.

본 논문은 고차원의 범주형 데이터에 대한 군집화에 대해서 다룬다. 기존의 범주형 데이터 객체를 위한 유사성(상이성) 계측들의 기저에 깔려 있는 한계점은 수치형 데이터에서와 같은 순서화 (ordering)의 부재와 데이터의 고차원성과 희소성에 기인하는데, 이를 효과적으로 극복할 수 있는 기법이 투영 군집화이다. 본 논문에서는 고차원의 범주형 데이터를 효과적으로 처리할 수 있는 투영 군집화를 다루며 핵심 요소인 군집 차원의 정의와 군집 응집도를 제안한다.

The purpose of this research is to examine that internal virtue (i.e. virtue between organizational members) and external virtue (i.e. virtue between organizational members and external members) positively associate with job performance when considering organizational identification, positive work-related identity, affective commitment, emotional exhaustion, and collective self-esteem as mediators. Virtue in organization has received attention as critical attribute of positive organizational scholarship. Cameron(2003) defined the study of virtue as a study of the capacity, attributes, and reserve in organization that facilitates the expression of positive deviance among organization member. In addition, this study contributes to the qualitative investigation on how internal giving virtue (i.e. the employees' virtue for their organization), internal receiving virtue (i.e. virtue employees receive from their organization), external giving virtue (i.e. the organization's virtue for society), and external receiving virtue (i.e. virtue the organization receives from society), used as independent variables, influence job performance after creating research model for the four virtuous behaviors through qualitative research. Therefore, this research contributes to the creation of research model for virtuous behaviors within organizations and virtuous behaviors with external members through qualitative study and sheds light on how these variables influence job performance by virtue of qualitative research.

The need for changes in archival studies curriculum has been steadily raised because of the wide variation of the curriculum in each graduate school. In this study, the foreign archival studies guidelines and certification standards were compared and analyzed to derive key categories and elements for developing the Korean guidelines for a graduate program in archival studies. The five key categories and elements of the guideline include introduction, mission and goal, knowledge categories, administrative factors, and conclusion. On the other hand, the 10 knowledge categories to be learned by archivists include ① The Nature of Records and Archives, ② Selection, Appraisal, and Acquisition, ③ Arrangement and Description, ④ Preservation, ⑤ Reference and Access, ⑥ Outreach, Instruction, and Advocacy, ⑦ Management and Administration, ⑧ Social and Cultural Systems, ⑨ Legal and Financial Systems, and ⑩ Information Technology. In the future, knowledge categories need to be actively reflected by the opinions of the academic community and archivists to improve the graduate curriculum.

In order to derive the success factors of a Mega-scale national project, this study conducted a questionnaire survey on experts participating in the Yongsan National Park development program to obtain critical success factors in the program definition phase. AHP analysis was performed for each category through a survey of experts participating in the definition phase of the Yongsan park development program to derive relative importance. The categories were classified into program strategy, process, and people, and the importance between categories was people, strategy, and process in that order. In addition, as for the 27 critical success factors in the program definition phase, the program manager's competency and leadership, environmental and cultural property survey planning, program management plan preparation, operation and maintenance philosophy, and integrated program office showed high priorities. Therefore, in promoting the Yongsan Park development program, we propose a strategy for selecting and focusing on the critical success factors with high priorities in the program definition phase proposed in this study.

The purpose of this study to understand the meaning of nursing through core basic nursing for nursing students before clinical practice. Participants of this study were analyzed through interviews after taking the core basic nursing skills class for 3rd graders who are currently enrolled in the Department of Nursing at M University. Seventeen students were enrolled in a K-city university as a third-year student who first performed core basic nursing skills. As a result of the study, it was derived into 3 categories and 19 thematic collections. The three categories included 1. meaning of help, 2. overcoming fear, and 3. opportunity to acquire nursing skills. The conclusion was that the first core basic nursing skills before clinical practice was a time to learn the true meaning of nursing through mutual help The difficulties were overcome with repeated practice, and the acquisition of newly learned nursing skills appeared as an effective process to experience with confidence. Therefore, it can be used as a useful basic data for counseling and guidance on the adaptation of nursing students to clinical practice, and it is expected that it will be used as a useful data for successful practice application counseling.

The aim of this study was to investigate the conditions and strategies of interaction for the school adjustment for the early entrance students of science academy for the gifted. To know their concerns and process of school adjustment, we interviewed six early entrance gifted students of the science academy and two gifted students preparing for their early entrance with a semi-structured questions. Using the grounded theory, a paradigm model was organized and a core category was abstracted through the open, axial, and selective coding. Based on the open coding analysis, 75 concepts, 21 sub-categories, and 10 categories were derived. In the axial coding, the paradigm model was organized by the link between 10 categories derived from open coding. Through the selective coding, this study discovered the core category about early entrance student's school adjustment was overcoming difficulties by using academic, social, and emotional strategy for school adjustment. Through this, we understand the school adjustment process of the students of early entrance to science academy for the gifted.

The purposes of this study are to categorize the archival body of knowledge based on the analysis of two guidelines and websites of 10 archival graduate programs in the United States, and to make suggestions for the development of archival education in Korea. Basic knowledge, core knowledge, complementary knowledge, practical knowledge, and research knowledge are found as components of the archival body of knowledge. The basic knowledge is the ability to understand general circumstances related to records and archives. The core one is to master the required competence as archivists. The complementary one is to understand other disciplinary backgrounds and their various research methods. The practical one is to be obtained from field experiences and the research one is to make a scholastic contribution through a deep research process. Curriculum development for preservation, electronic records management, use of computer technologies, archival services and advocacy, more interdisciplinary courses and internship programs are suggested as important factors for the future archival education. And cooperative research and appointment of more faculty members are also suggested. Finally, the development of guideline for Korean archival graduate programs are strongly suggested.
