Abstract OBJECTIVE Although radiosurgical practice mandates meticulous radiological follow-up, even the most efficient radiology department can be overwhelmed by the large number of radiosurgical patients who have undergone diagnostic studies for many years at many different institutions to follow many separate lesions. Although the task of assembling these studies is theoretically possible, because they are spread out in time and space, it is often impractical. We therefore sought to construct a computer-based system that could store images from multiple sources and present them instantly for review. METHODS We attached a flatbed film scanner to a standard desktop computer in our clinic and scanned selected sheets of film into an image database at each visit of a radiosurgical patient. “Low-tech” solutions were deliberately chosen—that is, to enhance ease and software compatibility, we used the operating system's directory structure for organization of data instead of proprietary software. Standard commercially available software was used to review studies that had been previously scanned. RESULTS During a 2- to 3-year period, images were scanned from 1129 studies performed on 435 patients. Images could be reviewed instantly and compared with current studies, and scanning a single piece of film required approximately 30 seconds. We estimate that the current capacity of our computer memory will satisfy our needs for approximately 12 years. CONCLUSION Assembly of an efficient and inexpensive system for image storage and retrieval suitable for radiosurgical practice is feasible and straightforward. Although our system is not a substitute for a radiology department, it obviates the constant frustration of “finding the films” and has become an essential part of our radiosurgical practice.

Big data is featured by multiple sources and heterogeneity. Based on the big data platform of Hadoop and spark, a hybrid analysis on forest fire is built in this study. This platform combines the big data analysis and processing technology, and learns from the research results of different technical fields, such as forest fire monitoring. In this system, HDFS of Hadoop is used to store all kinds of data, spark module is used to provide various big data analysis methods, and visualization tools are used to realize the visualization of analysis results, such as Echarts, ArcGIS and unity3d. Finally, an experiment for forest fire point detection is designed so as to corroborate the feasibility and effectiveness, and provide some meaningful guidance for the follow-up research and the establishment of forest fire monitoring and visualized early warning big data platform. However, there are two shortcomings in this experiment: more data types should be selected. At the same time, if the original data can be converted to XML format, the compatibility is better. It is expected that the above problems can be solved in the follow-up research.

Joint position sense (JPS) is commonly evaluated using an angle replication protocol with vision occluded. However, multiple sources of sensory information are integrated when moving limbs accurately, not just proprioception. The purpose of this study was to examine different availability of vision during an active JPS protocol at the shoulder. Specifically, the effects of four conditions of vision availability were examined for three target shoulder elevation angles (50°, 70° & 90°): vision occluded continuously (P-P); vision available continuously (VP-VP); vision occluded only during target memorization (P-VP); and vision occluded only during target position replication (VP-P). There were 18 participants ( M age = 21, SD = 1 years). We used separate repeated ANOVAs to examine the effect of condition and target angle on participants’ absolute error (AE, a measure of accuracy) and constant error (CE, a measure of directional bias). We found a significant main effect for condition and angle for both dependent variables ( p < 0.01), and follow-up analysis indicated that participants were most accurate in the VP-VP condition and least accurate in the P-VP condition. Further follow-up analysis showed that accuracy improved with higher target elevation angles, consistent with previous research findings. Constant error results were similar, as there was a prominent tendency to overshoot the target. Unsurprisingly, participants performed best at the angle replication protocol with their eyes open. However, while accuracy was reduced when vision was occluded during target memorization, it was restored during target replication. This finding may have indicated an accuracy cost due to introduced noise when transforming sensory information from a proprioceptive reference frame into a visual reference frame.

AbstractObjective:To evaluate the efficacy and feasibility of using a computer-based teaching tool (http://www.coolfoodplanet.org) for nutrition and lifestyle education developed for primary school children.Design:This was a 2-week school-based intervention in third and fourth grades. The study design was multi-factorial with repeated measures of nutrition knowledge, at three points in time, of dependent samples from control and intervention groups. Control schools (n=7) used ‘traditional’ nutrition education materials and intervention schools (n=8) additionally used the computer-based educational tool. Qualitative information was collected in focus group discussions with student teachers and pupils, and by observing the nutrition lessons.Setting/subjects:Pupils aged 8–11 years (n=271) from participating schools in Vienna, Austria.Results:Nutrition knowledge increased significantly in both intervention and control schools, irrespective of the teaching tool used (P<0.001). The significant effect was maintained at 3 months' follow-up. There was no detectable difference in nutrition knowledge post intervention or at follow-up between the two study groups. In intervention schools, younger pupils (8–9 years) had better nutrition knowledge than older pupils (10–11 years) (P=0.011).Conclusion:This computer-based tool increases the possibilities of school-based nutrition education. If the tool's weaknesses identified during the formative evaluation are eliminated, it has the potential to make learning about nutrition more enjoyable, exciting and effective. This is of great importance considering that ‘healthy’ nutrition is not necessarily a topic that easily attracts pupils' attention and in view of the potential long-term health benefits of early and effective nutrition education.

Deficient bone volume, anatomical limitations, lack of available mesiodistal space, adjacent teeth angulations, and surgical errors may lead to placement of narrow diameter implants. In such a scenario, functional and esthetic—yet sustainable—replacement of more than one missing tooth becomes quite challenging. This article describes the successful restoration of missing both mandibular central incisors on one 3-mm single-piece implant in 3 patients. Despite being a biomechanically complex presentation, the objectives of optimal outcome were achieved in all 3 patients by means of innovative design, fine control of occlusal factors, and correct choice of restorative material. Until the last follow-up at 5 years, no implant or prostheses loss was experienced.

To strengthen Human Security in border areas, the state must pay attention to many things. Various aspects of security continue to be carried out by looking at the multiple sources and potentials that exist, but it is undeniable that there are still many human insecurities. Regulatory potential such as government programs carried out as a form of follow-up to policies made by the Central Government based on the Law on the Protection and Security of Fishermen, Fish Cultivators, and Salt Farmers. To provide opportunities for small and traditional fishers to also be able to take advantage of marine products optimally so that they cannot compete with other fish entrepreneurs. Government policies are essential for the community in shaping human security in the Paloh border area, Sambas Regency, Indonesia. The role of the government and young activists is very much needed for the development of existing or new businesses. Governments that have policies in empowering fishing communities can make it easier for fishing communities to develop correctly.

Background and aimsResidents near industrial areas are exposed to several toxins from various sources and the assessment of the health effects is difficult. The area of Civitavecchia (Italy) has several sources of environmental contamination with potential health effects. We evaluated the association between exposure to pollutants from multiple sources and mortality in a cohort of people living in the area.MethodsAll residents of the area in 1996 were enrolled (from municipal registers) and followed until 2013. Long-term exposures to emissions from industrial sources (PM10) and traffic (NOx) at the residential addresses were assessed using a dispersion model. Residence close to the harbour was also considered. Cox survival analysis was conducted including a linear term for industrial PM10 and NOx exposure and a dichotomous variable to indicate residence within 500 m of the harbour. Age, sex, calendar period, occupation and area-based socioeconomic position (SEP) were considered (HRs, 95% CI).Results71 362 people were enrolled (52% female, 43% low SEP) and 14 844 died during the follow-up. We found an association between industrial PM10 and mortality from non-accidental causes (HR=1.06, 95% CI 1.01 to 1.12), all cancers (HR=1.11, 95% CI 1.01 to 1.21) and cardiac diseases (HR=1.12, 95% CI 1.01 to 1.23). We also found an association between NOx exposure from traffic and mortality from all cancers (HR=1.13, 95% CI 1.01 to 1.26) and neurological diseases (HR=1.50, 95% CI 1.01 to 2.20). Living near the harbour was associated with higher mortality from lung cancer (HR=1.31, 95% CI 1.04 to 1.66) and neurological diseases (HR=1.51, 95% CI 1.05 to 2.18).ConclusionsEstimated exposures to different pollution sources in this area were independently associated with several mortality outcomes while adjusting for occupation and socioeconomic status.
