In this research, a Universal map, which can be converted to individual maps for heterogeneous mobile robots, is proposed. A Universal map can be generated using our developed measurement robot, and it is composed of a textured 3D environment model. Therefore, every robot can use a Universal map as a common map, and it is utilized for various localization technologies such as view-based and LRF-based methods. In LRF-based localization, accurate localization is achieved using a specific map, which is generated from a Universal map. In a view-based approach, localization and navigation are achieved using rendered images. The use of a Universal map enables generation of these maps automatically. The effectiveness of this approach is confirmed through experiments.

Background: Previous studies demonstrated conflicting results about the association of sleep duration and hypertension. Given the potential relationship between sleep quality and hypertension, this study aimed to investigate the interaction of self-reported sleep duration and sleep quality on hypertension prevalence in adult Chinese males.Methods: We undertook a cross-sectional analysis of 4144 male subjects. Sleep duration were measured by self-reported average sleep time during the past month. Sleep quality was evaluated using the standard Pittsburgh Sleep Quality Index. Hypertension was defined as blood pressure level ≥140/90 mm Hg or current antihypertensive treatment. The association between hypertension prevalence, sleep duration, and sleep quality was analyzed using logistic regression after adjusting for basic cardiovascular characteristics.Results: Sleep duration shorter than 8 hours was found to be associated with increased hypertension, with odds ratios and 95% confidence intervals (CIs) of 1.25 (95% CI, 1.03–1.52) for 7 hours, 1.41 (95% CI, 1.14–1.73) for 6 hours, and 2.38 (95% CI, 1.81–3.11) for <6 hours. Using very good sleep quality as the reference, good, poor, and very poor sleep quality were associated with hypertension, with odds ratios of 1.20 (95% CI, 1.01–1.42), 1.67 (95% CI, 1.32–2.11), and 2.32 (95% CI, 1.67–3.21), respectively. More importantly, further investigation of the association of different combinations of sleep duration and quality in relation to hypertension indicated an additive interaction.Conclusions: There is an additive interaction of poor sleep quality and short sleep duration on hypertension prevalence. More comprehensive measurement of sleep should be performed in future studies.

As a result of experimental bite raising on 7 adult and 7 young monkeys, the histological observation on "relapse" after retention period was undertaken with following findings. 1. The bite raising was achieved by inferior backward rotation of the mandible. Then, alveolar bone was stabilized by the masticatory muscles, which acted on the alveolar bone via teeth under the newly established occlusion. 2. Concerning muscle tissue, differences were evident between adult and young monkeys. That is, the muscle tissue of adult monkeys revealed severe regressive change during bite raising and retention period, but no severe change revealed in the muscle tissue of young monkeys. 3. The adaptation of muscle tissue was rather difficult than that of bone tissue. 4. The adaptation of bone tissue was earlier and stronger than that of muscle tissue. 5. Even in five days after the bite raising, alveolar bone, zygomatic arch, mandibular angle and temporomandibular joint revealed bone resorption. Through the retention, these bones developed osteoblastic mechanism and increased stabilization longitudinally. This trend was more active in young monkeys. Additionally, the muscle insertion parts of adult monkeys accompanied the bone transformation. From the above findings, it is considered to be the adaptation difficulty of the muscle tissue that "relapse" after bite raising is induced. Therefore, the author proposed that the orthodontic treatment, which required jaw transposition, should be done during growth period as much as possible. Although the adaptation of muscle tissue was difficult after growth period, the capability was not completely denied
