Data is the expression of the language or numerical values that show some characteristics. And information is extracted from data for the specific purposes. The knowledge is utilized as information to construct rules that recognize patterns and make decisions. Today, knowledge extraction and application of the knowledge are broadly accomplished to improve the comprehension and to elevate the performance of systems in several industrial fields. The knowledge extraction could be achieved by some steps that include the knowledge acquisition, expression, and implementation. Such extracted knowledge can be drawn by rules. Clustering (CU, input space partition (ISP), neuro-fuzzy (NF), neural network (NN), extension matrix (EM), etc. are employed for expression the knowledge by rules. In this paper, the various approaches of the knowledge extraction are examined by categories that separate the methods by the applied industrial fields. Also, the several test data and the experimental results are compared and analysed based upon the applied techniques that include CL, ISP, NF, NN, EM, and so on.

Purpose: The purpose of this study was to explore the knowledge and learning needs on cardiac rehabilitation of coronary artery bypass graft(CABG) patients. Method: The subjects consisted of 100 CABG patients at A hospital in Seoul. Data were collected by the two different kind of questionnaires which measure knowledge and learning needs on cardiac rehabilitation of CABG patients. The subjects responded the questionnaire on knowledge before CABG and that on learning needs before their discharge. Result: The mean score of knowledge on cardiac rehabilitation was 68.54. Knowledge on risk factor, nature of disease, diet, daily activity, medication, post operative care were great in order. The mean score of learning needs on cardiac rehabilitation was 4.28. Learning needs on diet, medication, nature of disease, post operative care, daily activity, risk factor were great in order. There were significant differences in knowledge according to occupation, economic status and family history(p=.021, p=.017, p=.023). There was a positive correlation between knowledge and learning needs(r=.3009, p=.002). Conclusion: Level of knowledge on cardiac rehabilitation of CABG patients is low and knowledge on postoperative care is the lowest, and learning needs are great in ail categories.

Data are an expression of the language or numerical values that show some features. And the information is extracted from data for the specific purposes. The knowledge is utilized as information to construct rules that recognize patterns or make a decision. Today, knowledge extraction and application of that are broadly accomplished for the easy comprehension and the performance improvement of systems in the several industrial fields. The knowledge extraction can be achieved by some steps that include the knowledge acquisition, expression, and implementation. Such extracted knowledge is drawn by rules with data mining techniques. Clustering (CL), input space partition (ISP), neuro-fuzzy (NF), neural network (NN), extension matrix (EM), etc. are employed for the knowledge expression based upon rules. In this paper, the various approaches of the knowledge extraction are surveyed and categorized by methodologies and applied industrial fields. Also, the trend and examples of each approaches are shown in the tables and graphes using the categories such as CL, ISP, NF, NN, EM, and so on.

The purposes of this study were to investigate how children's categorization differs in object categorical hierarchy and to examine whether these aspects were different according to the children's age of 18 months, 24 months, 30 months. The participants consisted of 120 young children aged 18 months, 24 months, and 30 months from 31 child-care centers located in middle-income regions of Seoul and Kyonggi Province. The major findings were as follows : First, all the children from all three age groups could consistently differentiate the superordinates; however, they could not consistently differentiate basic categories. Second, 24 month appears to be a critical change period in category development. Third, as the children become older, they are able to acquire more knowledge regarding categories. These results suggested that the advent of ordering, in terms of basic categories as well as superordinates which occurred around the age of 24 month, was confirmed in category development.

Most countries recognize traditional knowledge as an economical resource in recent years, and so are actively participating in WIPO discussions for making sure of their intellectual property rights. In this study, the definition of traditional knowledge was discussed for making clear its categories and relative subjects. A tool for Korean Traditional Knowledge Resource Classification(KTKRC) was developed for putting the data of the resources in order, and was indispensable for searching for and examining cultural artifacts within the system of international intellectual property rights. KTKRC covers comprehensively our various traditional knowledge resources and has a similar structure to IPC for international searching, examining, and information exchange. KTKRC consists of a section of traditional knowledge(A), and three subsections: production technology(A0), living technology(A2) and creative technology(A4). The subsections include 8 classes, 28 subclasses, 105 groups, and a great number of subgroups.

Healthcare design has been considered as one of the most complex design types. In this study, healthcare design complexity is analysed by the following categories: (1) function; (2) medical technology; (3) scientific knowledge; (4) aesthetics; and (5) interest group complexity. The central questions here are: (1) What is the impact of specialized knowledge on the professional practice; and (2) What are the relationships between design complexity and specialized knowledge. To answer these questions, this study utilizes two approaches, including mail-out questionnaires survey and in-person and focus group interviews. This study found that healthcare design architects emphasize the technical component of specialized healthcare design knowledge. Thus they perceive that architectural research, as a tool to increase specialized healthcare design knowledge, is beneficial to solve the technical components including medical technology and functional problems. In the professional practice, however, architectural research is hardly conducted due mainly to the lack of money and time for it. Different perceptions regarding healthcare design complexity and architectural research among the firms exist, depending on the firm size. These results imply that the knowledge management strategy of large firms can be more efficient to the organizational growth than the small firms.

In the social information facilities with physical stacks, it is critical to arrange categories of knowledge since there should be conventional methods by which users and visitors can browse index of all sorts of media relating to their topics. The classical index system of knowledge has been developed with primitive libraries and museums and therefore the system can be addressed by analyzing typical cases of precedents. As the forth industrial revolution has emerged, there will be quite innovative approach to provide information to the public as well as the private. The coalition between knowledge and space has always been considered as essential characteristics that remind scholars of hierarchical layout of knowledge resources such as maps, books, documents and diverse specimens. This research assumes that the spatial layout of knowledge can be classified in terms of physical attributes, symbolic entities, and information media and it defines what coalition between knowledge and space is creative in order to enacting interactive dialogue among information navigators. The spaces in between the knowledges function as trasition areas where the index system informs and stimulates, where the interface between the different knowledges is optimized and therefore the library as the public facilities no longer dedicated to the text, but as an information space in which all sorts of media are distributed equally.

This study was conducted between October 1, 1998, and December 31, 1998, in order to provide basic data to develop better self-management educational programs for systemic lupus erythematosus (lupus) patients. In the study, the extent of each patients knowledge on the disease and their learning needs about it were examined for 100 lupus inpatients and outpatients at the Kangnam St. Marys Hospital. Data were collected by using questionnaires to those patients. Frequencies, percentage, average, standard deviation, t-test, ANOVA, and Duncans multiple range test were examined through the SAS program. The result of study follows : 1) The average score of patients knowledge on the disease was 15.7 (range, 7-20; standard deviation, 2.74). Subjects scored higher as far as the extent of their knowledge in the following categories : management of daily life, diet, characteristics of the disease, risk factors, and medication. Two categories shared the highest percentage of correct answers : 99% of subjects correctly identified that fatigue and stress aggravate symptoms of lupus and symptoms of lupus vary among individuals in range and type. However, when subjects were asked if patients should get a regular examination by an ophthalmologist every 4-6 months while they are on medication to treat rashes, lupus can be completely cured, and contraceptives that include a female hormone (estrogen) are good as contraceptive methods, the percentages of correct answers were low (32%, 31%, and 20%, respectively). In terms of subjects knowledge about the disease by their general characteristics, single subjects had more knowledge about the disease than married subjects did (t=2.14, p=0.0353). The extent of knowledge also varied by monthly income (F=4.96. p=0.0097). Those with more formal education had more knowledge about lupus than those who had less formation education did (t=2.95, 0.0039). Additionally, those who were satisfied with their education about the disease had better knowledge about it than those who were dissatisfied with their education did (t=2.71, p=0.0090). 2) The extent to which lupus patients wanted to be educated about the disease was, on average, 64.5 (range, 46-75; standard deviation, 7.91). Areas for which patients requested education are listed here in order : risk factors, sexual lives and patients associations. Patients who had been hospitalized demonstrated wanting more education than those who had not been did(t=3.73, p=0.0003). The extent to which they wanted the information was different by the number of educational sessions they had (F=3.98, p=0.0249). In conclusion, the results above would be considered when the education programme is planned for SLE patients.
