Crowdsourcing is being researched as a problem-solving technique by issuing open calls for solutions to large crowds of people with the incentive of prizes. This paper tackles the dual objectives of building cluster flight software and educating students using collaborative competition, both in virtual simulation environments and on real hardware in space. The concept is demonstrated using the SPHERES Zero Robotics Program, a robotics programming competition where the robots are nano-satellites called SPHERES onboard the International Space Station (ISS), traditionally used as a Guidance, Navigation and Control testbed in microgravity. Zero Robotics allows students to program SPHERES to play a game through a web-based interface and the most robust projects are evaluated on the ISS hardware, supervised by astronauts. The apparatus to investigate the influence of collaboration was developed by (1) building new web infrastructure where intensive inter-participant collaboration is possible, (2) designing a game that incentivizes collaboration with opponents, to solve a relevant formation flight problem and (3) structuring a tournament such that inter-team collaboration is mandated. The web infrastructure was also built using collaborative competitions, to demonstrate feasibility of building space software end-to-end by crowdsourcing.

The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.

Abstract The control rates of patients with hypertension remain extremely low in Chinese rural communities, therefor we aimed to improve treatment adherence and control rate for patients with hypertension by using a web-based management system, which included modeles of the user’s personal information, health education, adherence alerting, communication between physician and statistics analysis and data print functions. 350 patients with uncontrolled hypertension were included in the study through a multi-stage stratified sampling, and were divided radomis1y into the web-based intervention group and control group. Comparing with those in the control group, there was a significant improvement in the control rate of the blood pressure in the intervention group (93.7% vs 50.9%, p < 0.001) and a remarkable decrease in blood pressure (systolic blood pressure declined by 25.0 mmHg, < 0.001; diastolic blood pressure declined by 8.7 mmHg, p < 0.001) after 12 months follow-up. The medication adherence rate in intervention groups was improved significantly than that in the control group p < 0.01),and the adherence scale correlated negatively with blood pressure (r=-0.518, P < 0.001), and positively correlated with control rate (0.623, P < 0.001). This study suggested that the web-based hypertension management system is worth spreading in rural areas in developing countries.

Microgrids are a group of loads and distributed power generation sources acting as a single entity to provide power to the user or the grid. Since a Microgrid is a system of systems, this leads to an operability problem for local management and an interoperability problem for remote management. Operability and interoperability problems are solved by Data Acquisition and Control Systems (SCADA). There are several commercial platforms for the development of SCADA systems, being most of the time very expensive for the average user and even many universities. Therefore, this paper presents the design and implementation of a SCADA Web based on open-source software for experimental microgrids to allow the management of Microgrids remotely through the web. The Web-based SCADA system was developed for the Renewable Energy Laboratory (LabDER) of the Universitat Politècnica de València. An OMRON CPU CJ2M PLC was linked to a remote MYSQL database. A user interface was programmed using JAVA, and PHP languages perform operations and take data for the web-based SCADA system. The implemented SCADA system allowed monitoring and limited control of the LabdDER microgrid remotely, showing it to be an effective solution for Microgrids remote management.

Designed originally for document delivery, the Web is now being widely used as a platform for electronic commerce application software. The ad hoc enhancements that have made Web application software possible (for example, CGI and Java Script) have created an application support infrastructure where application software upgrades and maintenance are very complex. Yet the Web is the preferred platform for applications that have continuous ongoing development needs. In this chapter, we describe a model, an architecture, and an associated Web Application Support Environment (WASE) that both hides the low-level complexity of the existing Web infrastructure and, at the same time, empowers enterprise Web application programmers in their objective of writing modular and easily maintainable software applications for electronic commerce. WASE is not a compiler and does not completely abstract away the unique features of Web infrastructure. It is being constructed using XML documents in its API, to allow the function and configurability of applications to be defined in a Web-like fashion.

Abstract Since 2013, Directorate of NCD Prevention and Control has conducted web-based NCD risk factors surveillance with the data source from the ‘Posbindu PTM’ activity. Evaluation of the surveillance should be conducted periodically to assess achievement of objectives and target benefits. However, since the surveillance conducted nationally, there has not been a specific evaluation. This article aimed to obtain information about the utilization and problems in implementing NCD risk factors surveillance based on “Posbindu PTM” data. The research method was carried out through a systematic review of articles related to the implementation of NCD risk factor surveillance based on Posbindu PTM data in 2014 to 2020. The articles were searched using a search engine with keywords NCD surveillance, Posbindu PTM, Posbindu surveillance, in June 2020. There were 12 articles that match the keywords and five articles that meet the criteria. The results of the review showed that the data collection instruments of and technical guideline for surveillance of web-based NCD risk factors can be utilized by surveillance officers. The web information system is considered simple, acceptable, has high sensitivity and stability, and is timely. Automatic data collection, processing and analysis greatly facilitate surveillance. The results of the information system analysis are in accordance with the planning requirement. The results of surveillance are useful for outreach / counseling and for student research. The problems in implementing surveillance are the limited number of trained officers, no operational budget, limited population coverage, lack of infrastructure, interference with internet signals and limited peladens. Officers generally have not interpreted the results and disseminate less because of their limited abilities. The web-based PTM risk factor surveillance based on “Posbindu PTM” activity data can be implemented, but not systematically. Increasing the number and capacity of officers, especially in data interpretation improvement of surveillance facility is necessary to increase the benefits and achievement of the goal of prevention and control of PTM/NCD in the community. Abstrak Sejak tahun 2013, Direktorat Pencegahan dan Pengendalian Penyakit Tidak Menular (P2PTM) menyelenggarakan surveilans faktor risiko PTM berbasis web dengan sumber data kegiatan “Posbindu PTM”. Evaluasi surveilans seharusnya dilakukan secara periodik untuk menilai pencapaian tujuan dan manfaat yang ditargetkan. Namun, semenjak surveilans diselenggarakan secara nasional belum dilakukan evaluasi secara khusus. Artikel ini bertujuan memperoleh informasi tentang pemanfaatan dan permasalahan dalam pelaksanaan surveilans faktor risiko PTM bersumber data Posbindu PTM. Metode penelitian dilakukan melalui tinjauan secara sistematik terhadap artikel terkait pelaksanaan surveilans faktor risiko PTM bersumber data Posbindu PTM pada tahun 2014-2020. Pencarian artikel menggunakan mesin pencari dengan kata kunci surveilans PTM, Posbindu PTM, dan surveilans Posbindu pada Juni 2020. Terdapat 12 artikel yang sesuai kata kunci dan lima artikel yang memenuhi kriteria. Hasil tinjauan menunjukkan instrumen pengumpulan data dan petunjuk teknis surveilans faktor risiko PTM berbasis web dapat dimanfaatkan petugas surveilans dengan baik. Sistem informasi web dinilai sederhana, akseptabel, memiliki sensitivitas serta stabilitas tinggi, dan tepat waktu. Pengumpulan, pengolahan, dan analisis data secara otomatis sangat mempermudah pelaksanaan surveilans. Hasil analisis sistem informasi sudah sesuai kebutuhan perencanaan. Hasil surveilans bermanfaat untuk penyuluhan/ konseling dan untuk penelitian mahasiswa. Permasalahan pelaksanaan surveilans adalah keterbatasan jumlah petugas terlatih, tidak adanya anggaran operasional, keterbatasan cakupan penduduk, kurangnya sarana prasarana, gangguan sinyal internet, dan keterbatasan peladen (server). Petugas umumnya belum menginterpretasikan hasil dan kurang melakukan diseminasi karena keterbatasan kemampuan. Surveilans Faktor Risiko PTM berbasis web bersumber data kegiatan ‘Posbindu PTM’ dapat dilaksanakan, namun belum sistematik. Peningkatan jumlah dan kemampuan petugas, khususnya dalam interpretasi data, peningkatan sarana prasarana surveilans perlu dilakukan untuk meningkatkan manfaat serta pencapaian tujuan pencegahan dan pengendalian PTM di masyarakat.

IntroductionCommunication and information are cornerstones of management during major incidents and disasters. To support medical command and control, the Web-based support system called Paratus Major Incident can be used. The Paratus Major Incident system can provide management staff with online information from the incident area, and support management and patient handling at both single and mass-casualty incidents. The purpose of the Web-based information technology (IT) system is to ensure communication and information between the medical management at the scene, hospital management, and regional medical command and control (gold level).ExperiencesIn the region of Östergötland, Sweden, Paratus Major Incident system is used in operating topics such as: (1) information dissemination from the incident area; (2) communication between prehospital, regional, and hospital management; (3) continuous updates between the dispatch centre and medical commanders at all levels; (4) digital log-files for medical management and patient records; (4) database used for follow-up studies and quality control.ResultsDuring 2,161 incidents, 746 “first incident reports” from ambulance on scene were sent to regional medical command and control within 2 minutes. Four hundred and fifty-six “verification reports” were sent within 10 minutes. During 15 incidents, the designated duty officer on regional level confirmed “major incident” directly via the digital system, thereby notifying all arriving ambulance resources and involved medical managements.ConclusionThis Web-based IT system successfully has been used daily within prehospital management since 2005. The system includes medical command and control at the regional level and all involved hospitals in a major incident.
