Developing a trustworthy information system is a challenging task. The overall trustworthiness of an information system depends on trust relationships that are generally assumed without adequate justification. However, lack of appropriate analysis of such relationships and of appropriate justification of relevant trust assumptions might lead to systems that fail to fully achieve their functionalities. Existing literature does not provide adequate guidelines for a systematic process or an appropriate modeling language to support such trust-focused analysis. This paper fills this gap by introducing a process that allows developers to capture possible trust relationships and to reason about them. The process is supported by a modeling language based on a set of concepts relating to trust and control and a CASE tool. An illustrative example from the UK health care domain is used to demonstrate the applicability and usefulness of the approach.

The article deals with the problem of searching and selecting information. Currently, this kind of problem is solved by using search information systems. The main stage of creating a search information system is the development of the project, which is carried out using the unified modeling language UML and the CASE tool Power Designer. When developing a system project using the UML modeling language, all available information about the designed system is represented as a set of graphical elements, in other words, graphical structures. Such constructions are called diagrams. They reflect the essence of the system and consider it from different sides and represent the processes that take place in it in different ways.

Abstract Knowledge

Abstract - Knowledge management is needed right now, but many companies or institutions are constrained in conducting knowledge management because of the limitations of the information system. In Information Systems Study Program Universitas Terbuka still uses a manual system that uses Windows file explorer. This results in the difficulty of sharing information with outsiders. Therefore we need a web-based knowledge management information system design that can solve problems so far. The design model in this article uses the Unified Modeling Language (UML) model, which is a structural model and techniques for modeling object-oriented program (OOP) design. The results of the design of knowledge management information systems are expected to be able to help develop software later. Keywords: information systems, knowledge management, Unified Modeling Language (UML).   Abstrak - Knowledge manajemen merupakan hal yang dibutuhkan saat ini, namun banyak perusahaan atau lembaga terkendala dalam melakukan knowledge manajemen karena keterbatasan sistem informasi. Di Prodi Sistem Informasi Universitas Terbuka masih menggunakan sistem manual yaitu menggunakan windows file explorer. Hal ini mengakibatkan sulitnya berbagi informasi dengan pihak luar. Oleh sebab itu dibutuhkan sebuah perancangan sistem informasi manajemen knowledge berbasis web yang bisa menyelesaikan permasalahan selama ini. Model perancangan pada artikel ini menggunakan model Unified Modeling Language (UML) yaitu model struktur dan teknik untuk pemodelan desain program berorientasi objek (OOP). Hasil yang dari perancangan sistem informasi manajemen knowledge ini diharapkan bisa membatu pengembangan perangkat lunak nantinya.                                                                                                                     Kata Kunci: sistem informasi, manajemen knowledge, Unified Modeling Language (UML).

The Ideal

Seaports are genuine, intermodal hubs connecting seaways to inland transport links, such as roads and railways. Seaports are located at the focal point of institutional, industrial, and control activities in a jungle of interconnected information systems. System integration is setting considerable challenges when a group of independent providers are asked to implement complementary software functionalities. For this reason, seaports are the ideal playground where software is highly composite and tailored to a large variety of final users (from the so-called port communities). Although the target would be that of shaping the Port Authorities to be providers of (digital) innovation services, the state-of-the-art is still that of considering them as final users, or proxies of them. For this reason, we show how a canonical cloud, virtualizing a distributed architecture, can be structured to host different, possibly overlapped, tenants, slicing the information system at the infrastructure, platform, and software layers. Resources at the infrastructure and platform layers are shared so that a variety of independent applications can make use of the local calculus and access the data stored in a Data Lake. Such a cloud is adopted by the Port of Livorno as a rapid prototyping framework for the development and deployment of ICT innovation services. In order to demonstrate the versatility of this framework, three case studies relating to as many prototype ICT services (Navigation Safety, e-Freight, and Logistics) released within three industrial tenants are here presented and discussed.

The Revolution

The health care system in Libya in recent years does not change significantly, less developed and modernized. This problem is further exacerbated by the revolution that occurred in Libya. The revolution that occurred in 2011 has caused the health care system into collapse. In this study conducted a review for the development of health information systems in Libya by using OpenMRS Framework.At the stage of gathering information using questionnaires concluded that the majority of respondents (about 95.35%) wanted the development of a new system that can resolve the main problems that occurred in Libya, the health information system ineffective and inefficient in which this system has led to wastage of time and increased operating costs. Based on analysis of system vulnerabilities using PIECES method could also be concluded that the current system is not used effectively and efficiently. In this study is also presented on how to implement OpenMRS.Based on the results of the discussion it can be concluded that OpenMRS is a solution that can be taken for the development of a health information system that is fast, low cost, and is an open source application that only requires a little setting in the system of patient management and care. OpenMRS can be implemented to support the health services of a small clinic to the health services with enterprise scale. Therefore, OpenMRS could be the answer to the development of health information systems in various countries around the world, including Libya.

Abstract Background A perennial problem in information systems is the unidirectional flow of information. Bidirectional information systems are mechanisms by which consumers and providers generate, discuss and use information at each level of data collection. This paper describes opportunities in the health service delivery system for bidirectional information flow that can be established as part of the health information system to inform decisions, planning, and action by both providers and consumers of care. Methods The study was quasi-experimental and involved pre and post-intervention, cross-sectional surveys at intervention and control sites. The intervention was a Community Based Health Information System. Quantitative and qualitative data were collected. The surveys covered five health facilities in the intervention sites and five in the control sites in each of the six study districts. Five clients were interviewed at each intervention and control health facility. Communities served by the selected health facilities were included in household cluster sample surveys. Thirty clusters of 10 households, each with under-five children, were included in each community served by the selected health facilities. Quantitative data were cross-tabulated to compare health outcomes at intervention and control sites. A content analysis was performed on the qualitative data; themes and sub-themes that identified opportunities for bidirectional information-sharing were identified. Results We identified five nodal points in the health system that provide opportunities for bidirectional information sharing at the household, community, and health facility levels. Immunization coverage, skilled delivery, water treatment, and latrine use improved more at the intervention than control sites. Where all of the mechanisms were implemented, there was better performance in outcomes. Conclusion A conscious engagement of service providers and consumers in dialogue, using available health system information to iteratively inform decisions and actions, improves health outcomes.
