A Digital Signature Model Using XAdES Standard as a Rest Service

The digital signature of documents and degrees is a topic widely discussed in the Federal Public Administration. Several laws and ordinances were created to standardize the issuance, validation and legal validity of digitally signed documents in national territory, such as the ordinances created by the Ministry of Education (MEC) to regulate the issuance of degrees in digital format. These ordinances created guidelines and standards that must be adopted by Federal Universities for the signing of in digital format. The main objective of this work is to study these ordinances, the main technologies and digital signature standards used in the literature to create a digital signature system model for University of Brasília-UnB, which complies with the MEC and ICP-Brazil standards. Moreover, the model must be developed with the main standards and technologies in the market, cohesive to the current UnB architecture, easy to maintain and update to new standards that may emerge, and also be a fully open source project. An architectural model and a prototype in Java language were developed using XAdES4j library as a microservice intermediated by the bus used in UnB. The prototype developed was compared with the current digital signature system named C3Web. The comparative tests and results between the two solutions showed that the current system used in UnB does not perform the signature in accordance with the standard proposed by the MEC, in addition to being a private system using proprietary technologies for the execution of digital signatures. The tests performed with the proposed model demonstrated that it performs the digital signature in accordance with the XAdES-T standard, regulations of the MEC and ICP-Brazil. In addition, the solution presented a performance comparable to the current system used by UnB with a little more effective security than the current system used. The current model developed in this work can be a basis for the creation of future subscription systems for Brazilian Universities.

International standard HL7 FHIR as a working framework for development of common healthcare information space of the Republic of Belarus

The positions of theRepublicofBelarusin the field of ICT, the levels of medical data store and collection, HL7 FHIR standard are considered. International standard HL7 FHIR for the exchange of medical data, designed to improve the interaction of independent medical information systems and reduce the cost of developing interfaces. FHIR introduces the term Resource as the main unit of meaningful information for transferring and storing data, describes a set of information resources and a protocol for interacting with the resource store through a REST service or messaging. A fixed basic set of information resources is designed to cover 80 % of information scenarios. This standard is used in the national system of electronic prescriptions in theRepublicofBelarus.

Syntax-From-Doc

Producing syntax highlighting, code completion, and context-aware code documentation in IDEs is hard. It is especially hard at SAS where the age and complexity of the SAS programming language begets quirks and edge cases. To support the features expected in modern IDEs, SAS has historically relied on syntax information produced in an unscalable, opaque manual process. This article presents a case study of the multi-year project to replace this legacy process with a "syntax-from-doc" REST service that stores and serves syntax information as JSON objects that are extracted from SAS XML documentation. The goal of the project is to produce a scalable, continually updated single-sourcing process by which all SAS syntax information can be made uniform and available across our myriad products and services. Though not without bumps and bruises to show for the stumbles along the way, this project serves as an interesting example of leveraging modern continuous integration/continuous delivery tooling, multiple markup languages, and a diverse technology stack to solve a hard problem.

ProteinsPlus: interactive analysis of protein–ligand binding interfaces

Due to the increasing amount of publicly available protein structures searching, enriching and investigating these data still poses a challenging task. The ProteinsPlus web service (https://proteins.plus) offers a broad range of tools addressing these challenges. The web interface to the tool collection focusing on protein–ligand interactions has been geared towards easy and intuitive access to a large variety of functionality for life scientists. Since our last publication, the ProteinsPlus web service has been extended by additional services as well as it has undergone substantial infrastructural improvements. A keyword search functionality was added on the start page of ProteinsPlus enabling users to work on structures without knowing their PDB code. The tool collection has been augmented by three tools: StructureProfiler validates ligands and active sites using selection criteria of well-established protein–ligand benchmark data sets, WarPP places water molecules in the ligand binding sites of a protein, and METALizer calculates, predicts and scores coordination geometries of metal ions based on surrounding complex atoms. Additionally, all tools provided by ProteinsPlus are available through a REST service enabling the automated integration in structure processing and modeling pipelines.

Development of a Technology for Automation of Work with Sources of Information on the Internet

The article describes the technology for automation of work with sources of information on the Internet. The created technology includes a development of a web service for storing and processing data; creation of a client part for viewing, editing and deleting records from the service; development of a browser extension for instant addition of articles to a web service database. Addition of records to the service is implemented by the development of an extension to Google Chrome browser. Creation of an extension involves getting information about the author of the article, the title of the article, addresses, key expressions, and highlighted text. Regular expressions and recursive search are used to obtain information about the author of the text. The article offers algorithms for finding the name of a literary source and its author. In order to allow the web service to interact with other services or programs, a REST service was developed in the article. A graphical user interface to display and edit records was developed for the web service using the AngularJS JavaScript framework. For the client part, a mechanism of an on request citations search and a mechanism of reference list formation for the selected citations is proposed. For the on request citations search, the article suggests the algorithm of citations ranking. Appropriate plugins for Google Chrome have been developed, which allow to connect content levels, background, and pop-up with each other. Functions for authorization, receiving a token, information search launch, search for an author, and a bibliographic record creation have been created.

HUBUNGAN KEPUASAN PELAYANAN MAKANAN DAN SISA MAKANAN DENGAN KECUKUPAN GIZI PADA PASIEN KELAS III DI RUMAH SAKIT

Background : Satisfaction of patients is one of success indicator of hospital food management that influence the nutritional adequacy of patients. The satisfaction of patients can be seen from the taste, punctuality of distribution, waiter hospitality and the cleanliness of tools. The other quality indicators of nutrition services is leftovers.Objectives : Reviewing the relationship of the satisfaction of food and rest service satisfaction with nutritional success in class III patients in the Roemani Hospital of Muhammadiyah Semarang.Method : This study is descriptive analytic study by using cross sectional design. The taking of sample was done by concecutive sampling and it was gotten with 30 samples. The data collection was done by interview used the questionnaire guide of the satisfaction of hospital food, recall 24 hours to know the outside intake of hospital, weighing and observation of leftovers, also counting the nutritional adequacy by comparing nutritional intake from food and nutrinionl adequacy. The data was prosseced by chi square test.Results : The subject have good perception to the food service of hospital as much as 63,3%, leftovers beetween 56,7%, and nutritional adequacy as much as 96,7%. Conclusion : There is no urgent relation beetween satisfaction based on food service and leftovers to nutritional adequacy level.
