While on-line shopping is increasing, the "Consumer Protection Law in Electronic Commerce" obliges each internet shopping mall to provide its business information. Although most internet shopping malls provide their business information in the semi-structured format on the bottom of their homepages, the attributes and expression forms of business information are different each other. It makes consumers difficult to identify their business information and lowers public confidence. Hence this study proposes three approaches - HTML-based structure, XML-based structure, and XML data island-based structure - to structuralizing business information for correct expression. The experiment results showed that the business information extraction time by XML data island-based structure is independent of the size of the web document, while the time by HTML-based structure is dependent on the size. By comparing the business information extraction times, we show that XML data island-based structure is more efficient and effective than HTML-based structure.structure.

Until now, a lot of research on cyber security have been tried, but there have been few studies on overall relationships, including internal factors and external factors. Therefore, this study examined cyber security management considering not only internal elements of SMEs but also corporate management environment. The first qualitative analysis and the second quantitative analysis were conducted through mixed method research. Qualitative analysis was conducted through a semi-structured interview method, and three themes were found: insufficient cyber security management system, internal noncooperation for cyber security, and problems derived from decision-making system. In the quantitative analysis, multiple regression analysis was conducted on the data obtained through the questionnaire. The perception of cyber threats and internal support among independent variables positively influenced the cyber security management system or the dependent variable. Through this study, internal variables had a causal impact on the cyber security management system rather than external environment variables. This implies that the variables related to the organizational culture such as employees' perception are important. These results are expected to provide practical significance for enhancing the cyber security management system in SMEs.

The purpose of this study is to explore the essential meaning of Deokhu's culture in adolescent as a play space on Cyber. A phenomenological research method guided data collection and analysis. Qualitative research methods collected from 18 in - depth interviews using semistructured question types for 13 to 17 year - old adolescents living in Seoul Jamsil. As a result, As a result, adolescent's Deokhu culture started by stress and social and emotional desire, and especially it was utilized as a play space on the cyber of purchase activity of fandom and goods around SNS activities. This has a positive effect on self-awareness as well as self-identity formation. Above all, the shortage of play time due to heavy school entrance and the lack of socially provided play space make the cyber space as another play space for the adolescents.

This sturdy examined the effectiveness of Team-Based Learning(TBL) program according to learning attitude, learning motivation and self-directed learning of nursing students learning the anatomy. A 12week TBL program which they were made small group as 6-7 students aimed at anatomy aspects was given 145 freshmen. A triangulation that quantitative Research used paired t-test, Pearson Correlation Coefficient by SPSS WIN 18.0 and qualitative research was conducted content analysis. Through this subject, significant improvement was found in learning motivation(t=-2.97, p<.003) and self-directed learning(t=-2.40, p<.018). There was a significant positive correlation. TBL is useful teaching and learning method on nursing students. We suggest that it is needed to measure the educational effects of TBL against other subjects.

This paper is to evaluate the usability of two representative video meeting services currently used by university for research to improve the quality of university remote lecture. questionnaires based on Kano Model were designed and in-depth interviews were conducted to provide qualitative approaches. Screen-sharing functions, the one-dimensional functions was the most important function. and attractive functions had relatively diverse directions. For essential functions, there was a wide gap in quality due to user-specific equipment. The function in which other platforms exist or business-related was not important. Webex reacted negatively to the aging UI, while Zoom responded negatively to the unilateral mute function. In addition, the development direction was presented in five ways as a result of analysis of these results. under Corona-19 situation, I hope this study will lead to continuous research to make stepping stone for remoted educational development.

Using Spradley's ethnographic method, the study was designed to describe and understand the factors contributing to the occupational socialization of librarians. Three in-depth interviews and one observation were conducted with each of the sixteen participants who have practiced for longer than 5 years in libraries and were selected by theoretical sampling. Eight factors emerged from the data: education in universities, social changes, work, human relationships, users, the library organizational climate, social perception, and striving to enhance the professional. 'Overcoming a lack of understanding about the profession' was the cultural theme for describing and integrating the factors contributing to the occupational socialization of librarians.

The purpose of this study is to gain an understanding of the experiences of nurses in graduate school who fill multiple professional roles. The research's participants were women in the nursing profession studying towards postgraduate degrees. Their experiences were analyzed using Colaizzi's phenomenological method of qualitative research. The results showed that participants feel constantly short of time, pressure from the demands of their study, guilt owing to inability to fulfill family commitments, struggles related to the conflicts of multiple roles, and the feeling of satisfaction from accomplishing professional goals. This paper suggests that if nurses undergoing graduate study have an organized support system to help them perform the roles, they will find an identity in the nursing profession and will take care of their patients more professionally as a result. Such support depends in part on health administrators' greater understanding of the nurses' circumstances.

As the Internet is growing, the use of XML which is a standard of semi-structured document is increasing. Therefore, there are on going works about integration and retrieval of XML documents. However, the basis of efficient integration and retrieval of documents is to cluster XML documents with similar structure. The conventional XML clustering approaches use the hierarchical clustering algorithm that produces the demanded number of clusters through repeated merge, but it have some problems that it is difficult to compute the similarity between XML documents and it costs much time to compare similarity repeatedly. In order to address this problem, we use clustering algorithm for transactional data that is scale for large size of data. In this paper we use common structures from XML documents that don't have DTD or schema. In order to use common structures of XML document, we extract representative structures by decomposing the structure from a tree model expressing the XML document, and we perform clustering with the extracted structure. Besides, we show efficiency of proposed method by comparing and analyzing with the previous method.

In this paper, we propose a new indexing technique to solve various queries which have a strong good point not only database indexing schema take advantage of converting from semi-structured data to structured data but also performance is more faster than before. We represent structure information of XML document between nodes of tree that additional numbering information which can be bit-stream without modified structure of XML tree. And, We add in indexing schema searching incidental structure information in the process. In Querying schema, we recover ancestor nodes through give information of node using indexing schema in complete path query expression as well as relative path query expression. Therefore, it takes advantage of making derivative query expression with given query. In this process, we recognize that indexing and querying schema can get searched result set faster and more accurate. Because response time is become shorter by bit operating, when query occur and it just needs information of record set earch node in database.
