Objective: This study aimed to explore the readability and comprehensibility of the drug information on a patient leaflet for the senior by employing performance-based user-testing. Methods: We included 36 elderly (65 years old or older) as the senior group (intervention group) and 36 adults (40~59 years old) as the adult group (control). We developed a questionnaire to test if participants could access to drug information. After completing a questionnaire, the participant was interviewed about their understanding over the patient leaflet. We performed t-test, ${\chi}^2$-test or Fisher's exact test to examine differences between two groups in primary outcomes. Results: The senior were less likely able to find information (78%) than the adult (91%); they were much less likely able to understand information (42%) than the adult (69%). While we found differences between the ability of finding and understanding drug information in both groups, the senior group had greater difficulties in understanding all kinds of drug information. They had significant difficulties to remember information after reading the patient leaflet and frequently failed to find proper information even though they were allowed to access freely to the leaflet during interviewing. Conclusion: To secure safe and effective use of drugs for the senior, it is necessary to develop drug leaflets for the senior.

Objectives: In chemical hazard communication, information receiver's perception is a important factor, but the study on the perception was few. Therefore, this study evaluated the perception of managers and workers group about chemical hazard communication by chemical hazard communication tools that were being used in fields. Methods: 91 managers and 238 workers were surveyed in two companies where use chemicals. All subjects were asked about the comprehensibility and perception for MSDS and GHS Pictograms being used in their workplaces through face-to-face interviews. Results: Most of the respondents knew MSDS, and more than half of the respondents had used MSDS once or more per year. The level of use to find the information on chemicals with MSDS was higher in the managers in comparison with workers. Also, the managers could understand and find the information on MSDS easier(p < 0.05). In the question asking the meaning of GHS Pictograms, the managers responded more correctly, as well(p < 0.05). 86.8% of the managers and 62.6% of the workers were conscious of the possible health hazards of chemicals that they could be exposed at work. However, among the respondents conscious of the health hazards, only less than 70% were well aware of the contents of the health hazards correctly. Conclusions: In chemical hazard communication, it is very important to evaluate whether information receiver have proper and correct knowledge and perception or not and actions based on the evaluations as well as provide correct information.

The goal of data mining is to develop the automatic and intelligent tools and technologies that can find useful knowledge from databases. To meet this goal, we propose an efficient data mining algorithm based on the fuzzy decision tree. The proposed method combines comprehensibility of decision tree such as ID3 and C4.5 and representation power of fuzzy set theory. So, it can generate simple and comprehensive rules describing data. The proposed algorithm consists of two stages: the first stage generates the fuzzy membership functions using histogram analysis, and the second stage constructs a fuzzy decision tree using the fuzzy membership functions. From the testing of the proposed algorithm on the IRIS data and the Wisconsin Breast Cancer data, we found that the proposed method can generate a set of fuzzy rules from data efficiently.

Purpose: To test the reliability and validity of the Korean version of the Person-centered Climate Questionnaire-staff version (KPCQ-S) in long-term care institutions. Methods: A total of 297 staff in long-term care institutions including nine nursing homes (NHs) and 4 long-term care hospitals (LTCHs) were included. The KPCQ-S was developed following the WHO guidelines of the process of translation and adaptation of instruments. An internal consistency using Cronbach's ${\alpha}$ was tested for reliability. Exploratory factor analysis (EFA) was used to examine the construct validity. Convergent and discriminant validity were examined using Pearson correlation. Results: EFA demonstrated the construct validity of the 14-item KPCQ-S with three-factor solutions, specifically three factors (safety, everydayness, and community) in NHs and four factors (safety, everydayness, community, and comprehensibility) in LTCHs. Convergent validity was found in the correlation with the work satisfaction (r=.55). The KPCQ-S showed satisfactory internal consistency reliability (Cronbach's ${\alpha}=.91$). Conclusion: The KPCQ-S is found to be a reliable and valid tool for measuring staff perceptions of the person centeredness of long-term care environments.

Variable Message Sign (VMS), which provides drivers with direct information about state of traffic congestion and for prevent an accident, is the most effective method among the methods of providing information in Advanced Transportation Management System. Currently establishment and the VMS which is operated foundation lets in Guidelines on the use of Variable message sign (a book of the VMS) of 1999 November the Ministry Construction & Transportation, these contents mean main viewpoint on physical part such as message special quality variable (font, character size and line space, word interval) and position mainly among standard about establishment in general. But, it is true that using without effect verification on the character of VMS display and that using mode of stationary-centered. In this paper, it executed significance test to effort verification on the character of VMS display for more practical and effective information transmission based on the driver viewpoint For the researches; develop 3D-Simulation, select characteristics of driver's visual cognition behavior (the conspicuity, the legibility and the comprehensibility), evaluation each issue (day or night, 80km/h or 100km/h). Especially, that used the Eye Marker Recorder to measure of reading-time (legibility) thus, confirmed objectivity and reduce an observational error. The results showed that the conspicuity is Flashing> Stationary>Scroll. The legibility is not deference that Flashing between stationary form. Also the comprehensibility result showed that Flashing> Stationary>Stroll form.
