BackgroundBreast self‐examination is a convenient and effective way to detect breast abnormalities. Based on Dale's Cone of Experience theory, we hypothesized that the combination of a smartphone application with hands‐on practice would have a greater impact than using a smartphone application alone. The purpose of this study was to compare the effects of different educational methods on (a) knowledge, (b) attitudes, (c) skills, and (d) students' satisfaction with the learning methods.MethodsWe conducted a pre‐ and post‐test quasi‐experimental design and developed a smartphone application using a video clip. One experimental group received smartphone‐based education, another group received smartphone‐based education combined with hands‐on practice, and the control group received a one‐time classroom lecture. We administered a pre‐test, provided intervention, and conducted a post‐test.ResultsAmong the three groups, the knowledge and attitude of the experimental groups were significantly higher than that of the control group. In addition, the group using the combination of the smartphone application and hands‐on practice showed the highest score changes in skills and satisfaction with the learning methods.ConclusionsSmartphone application use combined with hands‐on practice could be an effective education method for breast self‐examination.

Vision-based AR registration technology is based on finding the known four-points in a camera image. However there are many obstacles and noises in sea environment such as wave, wake, sun-reflection, and so on. Moreover we have to use not only the camera image but also navigational information such as AIS or radar information. This paper describes the process of computer image processing and utilize of AIS information to estimate ship pose and which is to overlap the computer-generated navigational graphical information upon a display device on the bridge.

Women have less control over decisions about risky sexual behavior and condom use than men. This power imbalance makes women vulnerable when having sexual relationships with their partner. However, no measurement tool has been developed to measure female sexual resourcefulness, which measures women’s self-perceived sexual right to self-determination. This study examined the psychometric properties of the Korean version of the female sexual resourcefulness scale (FSRS). Convenience sampling was conducted using social networking services. The participants were 217 women in their early 20s. Validity and reliability were examined using item analysis, factor analysis, and correlation with self-efficacy on condom use and self-efficacy in refusing sex, and Cronbach’s alpha. Twelve items were selected for the study. Three factors were extracted through factor analysis, explaining 62.03% of the variance and showing a good model fit in the K-FSRS. Reliability was high, as indicated by a Cronbach’s alpha of 0.85. These results indicate that the K-FSRS may be an appropriate instrument for measuring sexual resourcefulness among young Korean women.
