This study analyses the effects of various angles in sculling on human body lift and drag by means of computational fluid dynamics, discusses the importance of sculling and provides a basis for the development of future water safety education programmes. Study subjects were based on the mean data collected from males in the age of 20s from a survey on the anthropometric dimensions of the Koreans. Moreover, lift, drag as well as coefficient values, all of which were governed by the angle of the palm, were calculated using 3-dimentional modelling produced by computational fluid dynamics programmes i.e. CFD. Interpretations were performed via general k-${\varepsilon}$ turbulence modelling in order to determine lift, drag and coefficient values. Turbulence intensity was set to one per cent as per the figures from preceding research papers and 3-dimentional simulations were performed for a total of five different angles $0^{\circ}$, $15^{\circ}$, $30^{\circ}$, $45^{\circ}$ and $60^{\circ}$. The drag and lift values for the differing angles of the hands during sculling movement are as follows. The lift and drag values gradually increased with the increasing angle of the palm, however, the magnitude of increase for drag started to predominate lift from $45^{\circ}$ and lift gradually decreased from $60^{\circ}$. Overall, it is concluded that the optimal efficiency of sculling can be achieved at the angles $15^{\circ}$ and $30^{\circ}$, and it is anticipated that greater safety and informative education can be ensured for Life saving trainees if the results were to be applied to practical settings. However, as the study was conducted using simulation programmes which performed analyses on the collected anthropometric dimension, the obtained results cannot be made universal, which warrants furthers studies involving varied study subjects with actual measurements taken in water.

In order to protect Rescue 119 workers exposed on the spot from potential infection, this study identified their awareness and practices of infection control so that it could help preventing them from infection and also provide basic materials necessary for pre-hospital infection control. This study applied questionnaire survey to total 215 Rescue 119 workers at fire stations in Jeonbuk province, Jeonnam province and Gwangju city from July 14 to Sept. 14, 2006 for the benefit of data collection. The questionnaire about possible associations between awareness and practices of infection control consisted of total 46 times across 6 categories such as washing hands during emergency activities ; fluid therapy and injection ; respirator maintenance; individual hygienics ; disinfectant supplies and equipments maintenance ; and control of infectious wastes. And collected data were processed using SPSS statistic program to analyze frequency and percentage, mean and standard deviation, Pearson's correlation coefficient, t-test and one-way ANOVA. As a result, this study came to the following conclusions : In terms of awareness about infection control, our respondents showed highest awareness about infectious waste control, and also showed highest level of practices in washing hands during emergency activities. Throughout all domains, awareness means were higher than practice means. In particular, infectious waste control was the domain of significant differences between awareness and practices. In terms of associations between awareness and individual characteristics, it was found that female rescue worker group and hospital/general hospital career group (before joining the Rescue 119) showed significantly higher awareness on statistic level. In regard to associations between individual characteristics and practices, it was found that female rescue worker group showed higher level of practices than male group on statistic level. This study also analyzed correlations between rescue workers' awareness and practice of infection control. As a result, it was found that the higher awareness was in correlations with the higher practices across all 6 domains including washing hands. In addition, the higher awareness of a questionnaire item was in significantly positive correlations with the higher practice of other items. However, our respondents showed high awareness about anti-infection, but low practices in reality. This indicates necessity of devising possible solutions to improve the practices as much as awareness. Especially, it was noted that major reasons for insufficient practices of infection control guideline come from unhabituated practices and lack of supports for infection-preventing supplies and protective device (mask, etc). Hence, it is necessary to provide more infection-preventing supplies for local rescue workers sufficiently, in parallel with steady habituation of infection control. Furthermore, it is required to manage and study infection control policies even at pre-hospital step in efforts for effective infection control, education and activities.

In allowing visitors to manipulate objects or models with their hands, science museums can become informal education institutions. However, little research has been conducted analyzing the specific interactions of visitors at museums and the effects that specific characteristics of interactive exhibit have on visitors. This research classified exhibits according to the three characteristics: the presentation of concepts, interaction with exhibits and concept levels. Further, relationships among engagement behaviors, visitors'attraction to exhibits, and the holding power of exhibits were analyzed. Using the three characteristics, 55 exhibits were classified into five styles. The results suggest that intriguing content and novel interfaces, maximizing information on science and technology, should be developed for the educational purpose of encouraging visitors to engage in active learning with interactive exhibits. The results of this study provide useful data that planners, designers, and instructors of science museums can use to maximize visitors' participatory learning and interactions.
