The aim of this study was to investigate the effects of aerobic exercise on sleep quality in age-related changes between young adults and middle-aged adults. Eight healthy young subjects (22.1±1.1 years old) and five healthy middle-aged subjects (45.2±4.6 years old) were recruited for this study. This present study examined body movements and self-reported sleep qualities with questionnaire for 2 weeks. Actigraph was set up on the right wrist to measure the body movements during sleep. During the first week, mean amount of body movement during sleep was calculated as standard body movement (Control). During the second week, subjects had high-intensive exercise (80% for young or 75% for middle-aged adults of maximum heart rate, HIE) and moderate-intensive exercise (65% for young or 60% for middle-aged adults of maximum heart rate, MIE) in the early evening of two days this week. Body movement during sleep of each exercise day was calculated. Results showed that body movement in HIE conditions was significantly decreased for young subjects (p<0.05) but the body movements in both HIE conditions and MIE conditions were not significantly decreased for middle-age subjects. Later, it was found that younger subjects improved in self-reported sleep quality slightly. However, middle-aged subjects did not improve in self-reported sleep quality at all. Also, seeing the results of objective %HRmax, it is difficult to decide the exercise intensity in middle-aged adults. Therefore, our study suggests that HIE aerobic exercises can improve sleep quality for young adults. Also, it is important for middle-age adults to conduct rating of perceived exertion or physical strength based exercise.

Introduction Recently, the spread of mobile phones, many people became to use IT on the go. Furthermore, the improvement of wireless networks, it became possible to use a lot of information. There is reported to be effective for defibrillation using an AED, it is not always easy to find and retrieve a nearby AED in emergency settings. We developed a smartphone system (AEDmap) displaying nearby AEDs located anywhere. This system is used with a GPS smartphone, This system can be shown on a map the location of an AED from anywhere. To understand the effectiveness, we measured the time to find an AED using our system(AEDmap). Method We both were developed in the smartphone and the server. AEDmap we have developed and distributed free through Apple's website. This time, we used it to measure. Characteristics of 20 participants, mean age was 38 years(Age, year, mean±SD 38.1±8.04 ). We measured the time participants when using the software. Results The time to display a map on the smartphone was the location of a nearby AED mean 27.7 ± 1.82 seconds. The result was an average 27.7 ± 1.82 seconds to display the location of a nearby AED. Conclusion In our system, we find the nearest AED within 30 seconds regardless of the locality. Now is the time that the popular smartphone, this system is considered to be useful.

This study is intended as a follow-up of the "Development of a Computer-Simulation Teaching Material Using Video Images for Endoscopic Education Concerning Gastric Cancer," which was published in Japanese Journal of Applied IT Healthcare in 2009. The purpose of this study is to evaluate simulation type materials for endoscopic education developed in the preceding paper. For this purpose, we conducted education for 82 medical students, and evaluated the learning history data of materials used. As a result, it was found that the eight quizzes in teaching materials are classified into 2 clusters according to the dependence on images. Further, in the evaluation of the extent diagnosis of the lesion with use of the criterion of "detection rate - over-detection rate", it was found that a NBI (dye) image is suitable for diagnosis than a normal image. From the results of this study, in endoscopic education, it is difficult to learn skills obtained by solving the quizzes related to diagnosis of an image, by the conventional learning text. Thus, it is necessary to learn both the quizzes related to medical knowledge and the quizzes related to diagnosis of an image. It is recommended that to enhance the diagnosis ability, images are more used. From the reason for this, we suggest that e-learning using the images such as the video images has advantage, particularly in endoscopic education.
