  • Aspect-Oriented Software Development(AOSD) is the software development methodology that classifies concerns of the system and identifies crosscutting concerns and organizes aspect class, and AOSD has emerged as an important user-oriented software development methodology with high maintainability. However, most of related studies worked on identification and specification and coding of crosscutting concerns. And there have been few studies on slicing technique for tracing method of specified crosscutting concerns. Therefore, this paper proposes slicing technique based on AOSD that identifies and specifies crosscutting concerns through interactive analysis between use cases; also, suggests slicing technique which improves traceability centering on identified crosscutting concerns; applies the aspect-oriented slicing technique to Learning Management System(LMS) for case-study. LMS is a cyber educational system that demands a lot of functional changes and expansion, so it is effective to apply AOSD with high maintainability in developing LMS; and shows the results that compared with related studies by comparing six elements.

  • At this point in time, the importance of cosmeceuticals is being emphasized. This report is about the cosmeceuticals usage analysis of actual condition and purchasing behavior of female undergraduates. I suggest the methods for the sustainable improvement of cosmeceuticals that will satisfy needs of more customers through market segmentation. The subjects of this study were 340 undergraduates of selected 2 women's Universities in Seoul. 300 replies among the total distibuted questionnaires were analyzed with SPSS WIN 15.0 Statistics program. Through the study, it appears that the most female undergraduates use cosmeceuticals and the usage of cosmeceuticals is to resolve their skin problems. The most popular places for the purchase of cosmeceuticals are department stores and the most important consideration on purchases is the effectiveness of products. It is discovered that sunscreens are the most used cosmeceuticals.

  • With the development of the Internet, users share their experiences and opinions. Since related keywords are used witho0ut considering information such as the general emotion or genre of an unstructured document such as a movie review, the sensitivity accuracy according to the appropriate emotional situation is impaired. Therefore, we propose a system that predicts emotions based on information such as the genre to which the unstructured document created by users belongs or overall emotions. First, representative keyword related to emotion sets such as Joy, Anger, Fear, and Sadness are extracted from the unstructured document, and the normalized weights of the emotional feature words and information of the unstructured document are trained in a system that combines CNN and LSTM as a training set. Finally, by testing the refined words extracted through movie information, morpheme analyzer and n-gram, emoticons, and emojis, it was shown that the accuracy of emotion prediction using emotions and F-measure were improved. The proposed prediction system can predict sentiment appropriately according to the situation by avoiding the error of judging negative due to the use of sad words in sad movies and scary words in horror movies.

  • The purpose of this study is to analyze the change of hospitals that patients safety and quality improvement by accreditation process and to examine the impact or interrelation of leadership, organizational culture, hospital management activities and recognition of hospital management performances. The data were collected through a review of the literature, and selfadministered survey with a structured questionnaires to 714 subjects from several medical staff members, administration staff members, nursing staff members, medical technicians and other staff members working in 23 accredited hospitals in Korea. In this analysis hierarchical multiple regression and structural equation model were used. The conclusion of this study provides a theoretical model for understanding organizational changes brought about by accreditation system. Factor on improvement of efficiency and raise the morale, rather than increase of medical income and reduce of the cost factors, had a stronger influence on the accreditation process. In the future, the hospital's participation to induce the accreditation program voluntarily will come up with an alternative policy concern about financial perspective. Also, the hospitals which preparing accreditation program to achieve the goal efficiently, will make use of transformational leadership through enhancing individual consideration and intellectual development to leading members participation. Additionally, non-accredited hospitals should aim at professional culture by innovative and creative approaches, and inviting members to learning and growth in the organization.

  • In this study, we conducted to derive some implications by analyzing the computer education framework proposed by K12CS in the United States in order to organize the software curriculum and conceptualization of computational thinking in Korea. First, we discussed the use of the term Computational Thinking as a Computing Thinking in Korea and compare it with the concept presented in the US curriculum. we derived that Computing Thinking and Computational Thinking are different in the focus and scope of problem solving. Second, considering the fact that Korean software curriculum does not consider the hierarchy according to the school and the grade, we reconstructed the curriculum based on the core practices and concepts which were suggested by the organization of K-12 Computer Science in the United States.

  • Internet has been applied to the educational field such as data search, lecture by motion picture, realtime examination. Most questions made for these remote examinations use methods of making questions randomly using fixed questions or item pools. The designed system in this paper makes questions without knowing MARK-UP language and after undergoing examinations on Web. Also it readjusts degree of difficulty automatically on the basis of the rate of correct answers. In addition, this enables learners to perform feedback learning after examinations and subsequently learners themselves to adjust their degree of difficulty and undergo reexaminations. The automatic selection system makes it easy to select questions, possible to expect average marks and number of questions made, and to prevent that questions may be made too easy or too hard. For a remote examination, as there are much possibilities of dishonesty such as examination by proxy so different types of problems are made, and problems of the rationality caused from that can be avoided.

  • According to current digital and information society, architecture related departments in universities give and educate computer courses to train top-level human resources suiting the needs of the time. The aim of this study is to curriculum of architecture related departments and to use the references for curriculum organization by understanding computer courses for architecture related departments. The results are as follows: (1) There are 100 departments (28.2%) in the field of architecture and 130 departments including an academic system that is the most departments. Also, there are 86 departments (39.8%) in the field of architecture engineering and 117 departments including an academic system. There are 77 departments in the field of interior architecture, which contain 48 departments (62.3%) of two- or three-year bachelor course college. (2) Department in the field of architecture opens a program study course in the second year of the program that is the most courses had been opened. First, most departments selected an order of learning a structure/detail construction techniques of architecture and design skills such as a foundation system and expression of the structure by hand in the first grade and processing it using a computer in the second grade. (3) BIM was opened in only three departments of 31 departments surveyed and was opened in a senior class. The reasons of still lack of BIM are the compatibility deficit of partners such as building structure, building equipment, securing lecturer, and still the dominant point of CAD in the field. (4) Six departments of 31 departments surveyed did not open a program study course as a major. That is to say, it is learned in a basic course or basic liberal arts education requirements (information area) of each department, or in an own program of each department. (5) The program study is only a means to create architectural drawings in department of the field of architecture. Thus, we should remember not only the drawing through the program but also drawing up a floor plan after understanding of methods such as constructional methods, detail drawing, and expression.

  • The purpose of this study is twofold: to theoretically review the 'resources-based view' (RBV) developed by D. Hammer and his colleagues as an alternative cognitive theory and to illustrate the usefulness of the theory by applying it to interpret a science learning activity in which undergraduate students worked together to construct a model of the seasons. The theoretical review was based on the exploration of relevant literature and dealt mainly with three types of resources: conceptual, epistemological, and practical resources. The trial application revealed that scientific models have been developed through the combination of different pieces of conceptual resources activated from participants, rather than emerging as unitary wholes. However, all the activated resources were not included into a model, and some of the conceptual resources acted as constraints to constructing a scientific model. The implications included that science educators should be attentive and responsive to students' resources and help them use the resources productively to learn science.

  • Purpose: The purpose of this study was to define cognition of the preceptors on the preceptor's role stress and competency pre-post preceptorship experience. Method: This study was designed as a one group pre-test and post-test study. The subjects of this study were 22 preceptors who had the preceptor preparation education and then worked as preceptor for four weeks at a university hospital. For data analyses, percentage, mean, paired t-test, Pearson's Correlation Coefficient were adopted with the use of SPSS WIN 10.0. Result: The results of this study showed that after the preceptorship experience, role stress of the preceptor decreased significantly compared to before the preceptorship experience. All of the score of sub domains was decreased. Especially, there was a significantly difference in education conducting and evaluation, personal relation and communication, professional development. Also, after the preceptorship experience, competency of the preceptor increased significantly compared to before the preceptorship experience. All of the score of sub domains was increased. Particularly, there was a significantly difference in socialization facilitator and educator except learning planning performance. There was a significant positive correlation between educational experience and the number of learner before preceptorship experience of general characteristics and competency, but was not correlation between general characteristics and role stress. Also there was not correlation between role stress and competency. Conclusion: The finding above indicated that the preceptorship was effective in decreasing preceptor's role and increasing preceptor's competency.

  • The 7th curriculum sets a basic direction based on learner centered teaching, with the aim of allowing students to develop their mathematical ability. Teachers' manuals are provided to help teachers fallow the basic direction and achieve the curriculum aims, but in practice they are not always helpful. Therefore, we reconstructed parts of a teachers' manual. This involved analyzing the contents of units 6, 7 and 8 of the elementary mathematics textbook 4 na to identify and outline the problems; introducing more detailed teaching methods and activities; and developing teaching learning materials. We tested the new version in several real classes and analysed the responses 6f teachers and students to examine the possibility of its practical use. The results suggest that the reconstructed version of the teachers' manual for units 6, 7 and 8 of textbook 4 na is of greater practical utility.
