Aligning information security with the image of the organization and prioritization based on fuzzy logic for the industrial automation sector
Get PDFThis paper develops the strategic alignment of organizational behavior through the organizations´ image, prioritization and information security practices. To this end, information security is studied based on the business requirements of confidentiality, integrity and availability by applying a tool which integrates the strategic, tactical and operational vision through the following framework: Balanced Scorecard - BSC (strategic) x Control Objectives for Information and Related Technology - COBIT (tactical) x International Organization for Standardization - ISO/International Electro Technical Commission - IEC27002 (operational). Another image instrument of the organization is applied in parallel with this analysis to identify and analyze performance involving profiles related to mechanistic, psychic prisons, political systems, instruments of domination, organisms, cybernetics, flux and transformation (MORGAN, 1996). Finally, a model of strategic prioritization, based on compensatory fuzzy logic (ESPIN and VANTI, 2005), is applied. The method was applied to an industrial company located in southern Brazil. The results with the application show two organizational images: "organism" and "flux and transformation ". The strategic priorities indicated a significant search for new business services and international markets. Regarding protection of information, security found the gap between "minimum" and "Reasonable" and in domain 8 (HR) of standard ISO/IEC27002, considered 71% protection as "inappropriate" and "minimal" in the IT Governance context

Get PDFHospital information systems: a study of electronic patient records
Get PDFThe importance of patient records, also known as medical records, is related to different needs and objectives, as they constitute permanent documents on the health of patients. With the advancement of information technologies and systems, patient records can be stored in databases, resulting in a positive impact on patient care. Based on these considerations, a research question that arises is "what are the benefits and problems that can be seen with the use of electronic versions of medical records?" This question leads to the formulation of the following hypothesis: although problems can be identified during the process of using electronic record systems, the benefits outweigh the difficulties, thereby justifying their use. To respond to the question and test the presented hypothesis, a research study was developed with users of the same electronic record system, consisting of doctors, nurses, and administrative personnel in three hospitals located in the city of São Paulo, Brazil. The results show that, despite some problems in their usage, the benefits of electronic patient records outweigh possible disadvantages
Semantic wikis and the collaborative construction of ontologies: a case study
Get PDFOntologies are complex artifacts. They should seek consensus on the use of a set of modeled concepts. Some authors propose that these devices would be beneficial if they were built collaboratively. This article aims to address the use of a semantic wiki as an alternative to the collaborative construction of ontologies, and describes its ontological structure. Wikis are known as tools for collaborative construction of content. The semantic wiki is a research effort to integrate the concepts of wikis with the semantic web. The case study presented shows an implementation in Semantic MediaWiki: the best known and most used semantic wiki features by the academic community and the organizational environment
Risk analysis in information technology and communication outsourcing
Get PDFThis research aims at evaluating the risk analysis process in Information Technology and Communication (ICT) outsourcing conducted by organizations of the private sector. The research is characterized by being a descriptive, quantitative and transversal type study, which was used the survey method. Data were collected through questionnaire, the sample is not random and we used a convenience sampling process. The research made contributions to understanding the risk analysis process in ICT services outsourcing, and identified statistically significant relationships between risk analysis, organization\u27s size and its industry, and between risk analysis and diversity of outsourced services
Recommender systems in social networks
Get PDFThe continued and diversified growth of social networks has changed the way in which users interact with them. With these changes, what once was limited to social contact is now used for exchanging ideas and opinions, creating the need for new features. Users have so much information at their fingertips that they are unable to process it by themselves; hence, the need to develop new tools. Recommender systems were developed to address this need and many techniques were used for different approaches to the problem. To make relevant recommendations, these systems use large sets of data, not taking the social network of the user into consideration. Developing a recommender system that takes into account the social network of the user is another way of tackling the problem. The purpose of this project is to use the theory of six degrees of separation (Watts 2003) amongst users of a social network to enhance existing recommender systems
Managing it as a business: the Lutchen\u27s gap in the 100 top organizations based in Brazil
No full textUm problema comum em gestão de TI, apontados pelos especialistas, envolve a falta de visão de negócio dos executivos de TI ao alinharem seus departamentos com as premissas estratégicas da empresa e esquecerem-se das funções táticas da TI, onde esta poderia ser gerida como um negócio. Esse é conhecido como o gap de Lutchen e por sua importância no contexto da gestão da TI, este artigo é complementar ao artigo de Rodrigues et al. (2009) e visa identificar a presença do gap de Lutchen, na gestão da TI entre as 100 maiores empresas sediadas no Brasil. Para tanto, procedeu-se a um levantamento do perfil da gestão de TI nessas empresas, na visão de seus executivos. Utilizou-se um questionário, respondido pelos executivos de TI, contendo 77 perguntas que varrem os quatro fundamentos da função da TI na empresa. Os principais resultados indicam que: (a) na função Alinhar, o desenho da TI apresenta dicotomias entre os objetivos dos negócios e os da TI; (b) na função Gerir, observa-se que os orçamentos de TI orientam-se para garantir a capacidade de entregae dos serviços de TI e diferem nos métodos de controle de custo, variando entre rateios por volume, overhead e custo ABC; (c) na função Entregar, as evidências indicam que a TI é gerida como uma capacitadora de negócios; e (d) na função Garantir a Qualidade e Segurança, muitos executivos de TI monitoram eventos de qualidade e segurança, mas limitam-se às operações básicas da TI. Em conclusão, o que se observa nas empresas pesquisadas é que a TI é vista como um sistema fornecedor de soluções,f sob demanda, dos negócios, mais do que como um instrumento capaz de garantir inovação e capacidade competitiva para as organizações.A common problem in IT management involves the lack of business vision on the part of IT executives who align IT to the strategic assumptions of the company, but forget the tactical functions of the former, managed as a business. This is known as the Lutchen\u27s gap. Because of its importance in the context of IT management, this paper is a complementary approach to the preceding one from Rodrigues et al. (2009) and aims at identifying the Lutchen´s gap presence in the management of IT among the 100 top companies located in Brazil. To do this, we proceeded to a description of the profile of IT management in these companies, controlled by the executive board. We used a questionnaire filled out by IT executives, containing 77 questions covering the four functions of IT in a company. The main results indicate that: (a) In the IT\u27s Alignment function, the design of IT reveals dichotomies between business and IT objectives (b) In the IT\u27s Management function, the IT\u27s budget is oriented toward ensuring "delivering" abilities to IT services and differing in the methods of cost control, ranging from apportion by volume, overheads and by ABC cost, (c) in the IT\u27s Deliver function, evidence suggests that IT is managed as a business enabler; and (d) in the IT\u27s Quality and Safety Assurance, IT executives monitor quality and safety events, but are limited to IT\u27s basic operations. In conclusion, in the companies surveyed, IT is seen much more as an" on-demand solution provider", rather than as an instrument of innovation and competitiveness enabler for organizations
Networks versus ICT use: the case of sme from Bahía Blanca, Buenos Aires (Argentina)
Get PDFCooperative networks are main tools to improve the competitiveness of Small and Medium Size Enterprises (SME). This study contributes to extend the literature review about the factors that foster firms\u27 cooperative conduct. Apart from that, the paper examines through a LOGIT model, the firm\u27s characteristics, especially ICT (information and communication technologies) use, and the environment\u27s and partners\u27 characteristics that influence the probability of building alliances with other firms from the same economic activity. In particular, we find that ICT use reduces the probability of networking.Los acuerdos cooperativos son considerados herramientas importantes para mejorar la posición competitiva de las Pequeñas y Medianas Empresas (PYMES). Este estudio realiza un aporte a la revisión de la literatura, con respecto a los factores que fomentan el comportamiento asociativo. Por otro lado, examina a partir de un modelo LOGIT las características de la empresa, con énfasis en el uso de las TIC, su entorno y sus socios que inciden sobre la probabilidad de configurar alianzas con otras empresas de la misma rama o sector. En especial, se encuentra que el uso de las nuevas tecnologías de la información y de la comunicación disminuyen la probabilidad de formar alianzas
