As shown in Wikipedia, tagging or cross-linking through major keywords in a document collection improves not only the readability of documents but also responsive and adaptive navigation among related documents. In recent years, the Semantic Web has increased the importance of social tagging as a key feature of the Web 2.0 and, as its crucial phenotype, Tag Cloud has emerged to the public. In this paper we provide an efficient method of automated in-text keyword tagging based on large-scale controlled term collection or keyword dictionary, where the computational complexity of O(mN) - if a pattern matching algorithm is used - can be reduced to O(mlogN) - if an Information Retrieval technique is adopted - while m is the length of target document and N is the total number of candidate terms to be tagged. The result shows that automatic in-text tagging with keywords filtered by Information Retrieval speeds up to about 6 $\sim$ 40 times compared with the fastest pattern matching algorithm.

Purpose: The purpose of this study was to identify differences in knowledge, attitude, sexual experiences, and intention of safe sex behavior between pornography exposures and non-exposures. Methods: The subjects of this study consisted of 196 non-exposures and 160 exposures among high school students in the Chungnam Province. Data were collected from Dec.1 to Dec. 23, 2005. Result: The results of this study were as follows: The pornography exposures had more liberal attitudes, more sexual intercourses in sexual experiences, and less intention of safe sex behavior than the pornography non-exposures. There was no significant differences in sexual knowledge between the pornography exposures and non-exposures. Especially the score of knowledge related to contraceptive methods and venereal diseases was relatively low in both groups. Conclusion: The findings of this study showed that pornography can affect sexual attitudes, sexual experiences, and intention of safe sex behavior. An effective 'safe sex' education program needs to be developed for high school students. especially for pornography exposures.

BACKGROUND/OBJECTIVES: Educational interventions targeted food selection perception, knowledge, attitude, and behavior. Education regarding irradiated food was intended to change food selection behavior specific to it. SUBJECTS AND METHODS: There were 43 elementary students (35.0%), 45 middle school students (36.6%), and 35 high school students (28.5%). The first step was research design. Educational targets were selected and informed consent was obtained in step two. An initial survey was conducted as step three. Step four was a 45 minute-long theoretical educational intervention. Step five concluded with a survey and experiment on food selection behavior. RESULTS: As a result of conducting a 45 minute-long education on the principles, actual state of usage, and pros and cons of irradiated food for elementary, middle, and high-school students in Korea, perception, knowledge, attitude, and behavior regarding the irradiated food was significantly higher after the education than before the education (P < 0.000). CONCLUSIONS: The behavior of irradiated food selection shows high correlation with all variables of perception, knowledge, and attitude, and it is necessary to provide information of each level of change in perception, knowledge, and attitude in order to derive proper behavior change, which is the ultimate goal of the education.

Purpose: The purpose of this study was to compare the effect of breast self-examination (BSE) education between at education and three months. Method: The study subjects were consisted of 30 women chosen from those in a Catholic church in Seoul. The data was collected by using questionnare at two different times: immediately after the BSE education and 3 momths after. Result: At three months, women who performed BSE was 50.0% and the number of BSE practce was 2.53. There was statistically significant change on the score of the knowledge, barrier and practice between at education and three months later. Susceptibility was increased after three month, but wasn't significant different. Confidence, motivation after three months were decreased from the time of initial BSE education and wasn't significantly changed. It was found that motivation about BSE explained 44.2% of variance. Conclusion: The findings showed that the knowledge of BSE, and attitudes and practice were change between at the time of the first survey and at three months. Therefore, the intensive education about BSE can be effective to enhance women's health belief and practice to perform BSE for early detection of breast cancer.

Purpose: The purpose of this study was to identify the theoretical characteristics and direction of inquiry in the discipline of nursing by analyzing doctoral dissertations. Method: The materials used in this study were 277 doctoral dissertations from five universities in Korea. The framework for the study was derived from Kim's(l993) alternative linkage among philosophy, theory, and method in nursing science. Result: Of the 277 dissertations it was found that there were 13 types of linkages out of a possible 54 types. Most of the dissertations (128 of 277) were done within the linkage of realism/etic/quantitative/explanatory knowledge type. Of the 218 dissertations within scientific realism, 42 were within relativism, and 17 within practicism. There were 134 dissertations of the explanatory knowledge type, 112 descriptive ones, and 31 prescriptive ones. Studies done within the etic quantitative methodology included 209 dissertations and within the emic perspective, 43 with qualitative methodology, and 7 with quantitative. Conclusion: The results show that it is necessary to develop more alternative linkages for nursing practice and this will lead to expanding nursing knowledge.

Purpose: This study was performed to identify the affecting factors on health behavior of university students during pandemic Influenza A (H1N1). Method: The participants in this study were 283 students in H university. Data were collected through self-reported questionnaires in September, 2009. The collected data were analyzed by ANOVA, Pearson correlation and stepwise multiple regression using SPSS/WIN 18.0. Result: The percentage of correct answers regarding knowledge of Influenza A (H1N1) was 34.6%. Risk perception and compliance of health behavior were very poor, $17.92{\pm}6.26/30$ and $2.00{\pm}1.68/9$, respectively. There was a positive correlation among knowledge, risk perception and health behavior. Knowledge and risk perception of Influenza A (H1N1) and intention of getting an influenza vaccination for this year explained 16.3% of variance in health behavior. Conclusion: An educational program focusing on strategy to enhance university students' knowledge and risk perception of Influenza A (H1N1) would be effective in improving their health behavior against it.

Although a wide range of theoretical researches have emphasized on the importance of knowledge management in cooperative R&D network, the empirical researches to synthetically examine the role of organizational learning and open innovation which influence on the performance of technological innovation are not enough to meet academic and practical demands. This study is to investigate the effect of open innovation and organizational learning in venture business on technological competitive advantage and establish the mediating role of organizational learning. For the purpose, the questionnaires, made based on the reviewing previous researches, were collected from 274 Korean venture businesses whose managerial focus is on developing technological innovation. As a result of analysis, the relational dimensions of open innovation - network, intensity and trust shared by a firm with external R&D partners - as well as the internal organizational learning system and competence have positive influence on building technological competitive advantage whose sub-variables are technological excellence, market growth potential and business feasibility. In addition, it is identified that organizational learning has the mediating and moderating effect in the relationship between open innovation and technological competitive advantage. These results imply that open innovation complements and expend the range of limited resources and the scope of innovation in technology-intensive small and medium-sized enterprises. Besides, organizational learning activity reinforces the use of knowledge and resources, obtained from external R&D partners. On the basis of these results, detailed issues and discussion were made in the conclusion.

A method to automate hazard analysis of chemical plants is proposed in this paper. The proposed system is composed of three knowledge bases - unit knowledge base, organizational knowledge base and material knowledge base, and three hazard analysis algorithms - deviation, malfunction and accident analysis algorithm. Hazard analysis inference procedure is developed based on the actual hazard analysis procedures and accident development sequence. The proposed algorithm can perform hazard analysis in two methods and represent all conceivable types of accidents using accident analysis algorithm. In addition, it provides intermediate steps in the accident propagation, and enables the analysis result to give a useful information to hazard assessment. The proposed method is successfully demonstrated by being applied to diammonium phosphate manufacturing process. A system to automate hazard analysis is developed by using the suggested method. The developed system is expected to be useful in finding the propagation path of a fault or the cause of a malfunction as it is capable to approach causes of faults and malfunctions simultaneously.
